Definitions
- the present invention relates to a hairdressing and cosmetic comb used mainly for cutting or dyeing hair, and hair-dressing and cosmetic method.
- combing a comb
- dyeing hair likewise, hair is dyed after performing combing several times.
- General combs have a plate-like shape as shown in FIG. 12 , and have a support 32 with an approximately rectangular shape in a front view, comb teeth 33 formed on one side thereof, and a handle 34 provided continual from the support 32 .
- Those combs are often made of synthetic resins, such as celluloid.
- a beautician cuts long hair, he/she parts the hair of a head into a required number of parts, and arranges hair part by part to make it easier to cut the hair before cutting (hereinafter called “blocking”). Then, the beautician performs combing several times with the comb held in one hand, and holds hair, caught by the comb teeth, between fingers of the other hand. Next, the beautician holds the comb with the other hand, and cuts the hair with scissors. This work requires that the beautician shifts the comb from one hand to another a number of times during cutting. In cutting the whole head hair of a child, for example, even a skilled beautician needs to shift the comb from one hand to another 30 to 40 times.
- a cutting comb has been proposed in, for example, Patent Document 1.
- the comb includes a parent comb and a child comb, so that hair combed with the parent comb is held by the comb teeth of the child comb to ensure shaping to the cutting expected position, allowing the hair to be cut with scissors as it is without changing fingers to hold the hair.
- the structure of the cutting comb requires the process of producing the parent comb and the child comb separately and then fitting them together, thus raising a problem of increasing the manufacturing cost.
- the area of the portion where the comb teeth of the cutting comb are provided is as small as the conventional one. Therefore, the amount of hair which can be caught in single combing is still small, raising a problem that it is not possible to efficiently perform a work of cutting or dyeing a large amount of hair of the whole head.
- a hairdressing and cosmetic comb according to the invention and a hairdressing and cosmetic method using the comb are configured as follows.
- a hairdressing and cosmetic comb including a support; a plurality of comb teeth provided on one side of the support in a row substantially in parallel, the comb teeth each having lengths of 7.0 to 23.0 cm from a base to a tip and each being elastically bent and deformed to have a deformation of 1.0 cm or greater and 6.0 cm or less in a thickness direction of the comb teeth according to a form of a head when the comb teeth are pressed toward the head on which the comb teeth abut via a contact portion.
- the comb teeth may have widths of 1.0 to 12.0 mm in a side-by-side layout direction of the comb teeth, and thicknesses of 1.0 to 5.0 mm.
- a sectional shape of each of the comb teeth in the side-by-side layout direction of the comb teeth may be a rectangle defined by W>H where W mm is the width in the side-by-side layout direction of the comb teeth and H mm is the thickness of the comb teeth. Therefore, the long sides of the rectangles of the comb teeth in cross section abut on the head.
- the widths of the comb teeth in the side-by-side layout direction thereof may be constant at an intermediate portion from the base of each comb tooth to the tip thereof.
- the lengths of the plurality of comb teeth from the bases to the tips may be set in such a way that the length of the comb tooth provided at a center portion of the support is longest, and the lengths of the other comb teeth become shorter toward rightward and leftward end portions of the support from the center portion. Accordingly, the comb teeth provided in the center portion of the support deform more than the other comb teeth. Relatively speaking, the comb teeth which are provided apart from the center portion of the support deform less than the comb teeth which are provided in the center portion of the support.
- an interval of the comb teeth may be less than 0 to 3.0 mm.
- the comb teeth may be made of a synthetic resin, and may have the widths of about 6.0 mm in the side-by-side layout direction thereof, and the thicknesses of about 4.0 mm, and an interval of the comb teeth may be about 1.0 mm.
- At least one contact surface at which the adjoining comb teeth contact each other may be formed in the interval between the comb teeth and between the base and the tip of each comb tooth.
- the comb teeth may be bent in the thickness direction of the comb teeth.
- a hairdressing and cosmetic method includes abutting the comb teeth of the hairdressing and cosmetic comb according to any one of the first to ninth aspects of the invention on a head; sliding the hairdressing and cosmetic comb while pressing a contact portion toward the head to put through hair of the head between the comb teeth to elastically deform the comb teeth according to a form of the head, thereby combing the hair for hair-dressing and cosmetic work.
- hair can be caught in the gaps between almost all comb teeth, including the comb teeth provided at end portions of the support as well as the comb teeth provided in the center portion of the support.
- a practitioner can shorten the time of a hairdressing and cosmetic work.
- the comb can be designed in an easy-to-handle shape.
- the comb teeth since the comb teeth stably receive stress while being pressed to slide toward the head, a practitioner can slide the hairdressing and cosmetic comb smoothly.
- the area of the opposing sides of the adjoining comb teeth where the comb teeth contact the hair can be enlarged. This can allow hair to be firmly caught between the comb teeth.
- the comb teeth it is easy to greatly bend the comb teeth provided in the center section of the support. Accordingly, the comb teeth can be easily pressed against the curved shape of a head.
- a practitioner can easily place the comb teeth of the hairdressing and cosmetic comb against the curved shape of a head and easily slide the comb teeth.
- a practitioner can catch more hair with the comb teeth than can be done conventionally.
- hair can be firmly caught as well as can be combed with the comb teeth. Accordingly, since a practitioner can perform a hairdressing and cosmetic work with a lot of hair caught with the comb teeth, he/she need not perform blocking or shift the comb from one hand to another. In cutting hair, a practitioner does not easily damage his/her own fingers with scissors, and can easily cut hair straight. Further, it is easy to compare the finished image of the whole head with the current state of the work in progress.
- the practitioner can improve the efficiency of the whole hairdressing and cosmetic work by using the hairdressing and cosmetic comb and the hairdressing and cosmetic method using the comb to which the invention is applied. Since the operation of the comb teeth is simple, the practitioner can handle the comb easily, so that even a non-expert practitioner can use this hairdressing and cosmetic comb. Further, because of its comparatively simple structure, the hairdressing and cosmetic comb can be mass-produced at a low cost.

- the support 2 has a bottom surface portion 2 c, the comb teeth 3 are provided on that side which faces the bottom surface portion 2 c, and the support 2 is continual to bases 3 a of the comb teeth 3 .
- the support 2 may have a form such that the right and left side portions 2 d, 2 e extend over in the side-by-side layout direction of the comb teeth 3 .
- projecting end portions 2 f may be formed by reducing the diameter of the support 2 once and then enlarging it toward the bottom surface portion 2 c.
- the thickness of the support 2 is substantially the same thickness H of the comb teeth 3 in FIG. 1 , but should not necessarily be substantially the same thickness.
- the thickness of the support 2 may be thicker or thinner than the thickness H of the comb teeth 3 , and may be partly thicker or thinner than the thickness H of the comb teeth 3 .
- a hand-holding portion 2 g protruded or recessed on the support surface 2 a or 2 b may be provided.
- a thin teeth portion 2 h may be provided at one or both of the right and left side portions 2 d and 2 e.
- the thin teeth of the thin teeth portion 2 h are short and hard, and are not therefore elastically deformed like the comb teeth 3 .
- a practitioner can perform a hairdressing and cosmetic work on the whole head 5 using the comb teeth 3 , and perform a hairdressing and cosmetic work on a detailed portion using the thin teeth portion 2 h.
- a handle 2 i may be provided at one of the right and left side portions 2 d, 2 e. Holding the handle 2 i makes it easier for the practitioner to press the hairdressing and cosmetic comb 1 .
- comb teeth 3 which are different from the comb teeth 3 which catch hair 6 may be provided on the bottom surface portion 2 c side.
- a length s of the comb teeth 3 on the bottom surface portion 2 c side is comparatively short, and an interval L of the comb teeth 3 is comparatively long.
- the width, W, and thickness, H, of the comb teeth 3 on the bottom surface portion 2 c side may be set adequately.
- the support 2 can be molded of a synthetic resin, such as polypropylene or epoxy resin, integrally with the comb teeth 3 to be described later.
- a synthetic resin such as polypropylene or epoxy resin
- the raw material of the support 2 is not limited to a synthetic resin, and other materials, such as wood and metal, may be used as well.
- the comb teeth 3 are provided in a row substantially in parallel to one another with gaps 4 therebetween, as shown in FIG. 1( a ). Although the number of the comb teeth 3 is 15 in FIG. 1( a ), which is not necessarily restrictive and may be set to any adequate number.

- FIG. 3( b ) is a diagram showing another form of the tip side of the comb tooth 3 .
- the left-hand side shows a front view
- the right-hand side shows a right side view.
- the comb tooth 3 has, between a base 3 a and a tip 3 d, an intermediate portion 3 b and a narrow portion 3 c whose diameter gradually decreases from the intermediate portion 3 b, as shown in FIG. 1 and FIG. 3( a ).
- the base 3 a is the boundary portion between the support 2 and the comb teeth 3 hereinafter.
- the length s of the comb teeth indicates the length from the base 3 a to the tip 3 d hereinafter.
- the tip portion 3 x is the portion which includes the narrow portion 3 c and the tip 3 d hereinafter.
- the intermediate portion 3 b is formed linearly in the side-by-side layout direction of the comb teeth 3 in FIG. 1( a ), it is not necessarily limited to the linear shape.
- a part of the intermediate portion 3 b may be curved in the side-by-side layout direction so that an interval L of the gap 4 on the base 3 a side is different from an interval L of the gap 4 on the tip portion 3 x side, as shown in FIG. 5 . Accordingly, when the hair 6 is put through the gaps 4 which have the relatively shorter interval L, the presence of the gaps 4 which has the relatively longer interval L on the base 3 a side makes it easier to feed the hair 6 toward the base 3 a from the tip portion 3 x side of the comb teeth 3 .
- the intermediate portion 3 b may be curved in the thickness direction of the comb teeth 3 , or may be bent at a proper location in addition.
- the curved shapes of a plurality of comb teeth provided on one comb may match with, or may differ from, one another.
- the curved shape of the intermediate portion 3 b may be an arc, an elliptic arc, or a hyperbola.
- the radius of curvature is in the range of 5.0 to 10.0 cm. Within the range, the comb can be compatible with the radiuses of curvature of general human heads covering from children to adults, and are suitable as a hair-dressing and cosmetic comb.
- the lateral cross sectional shape of the intermediate portion 3 b is approximately rectangular.
- the sectional shape of the intermediate portion 3 b may not be limited to the approximately rectangular shape, and may take another shape, such as approximately circular shape, approximately elliptical shape, or polygonal shape.
- the width W and thickness H of the intermediate portion 3 b is constant from the base 3 a to the narrow portion 3 c.
- a portion with a partly larger width W or a portion with a partly narrower width W may be provided, and a portion with a partly larger thickness H or a portion with a partly smaller thickness H may be provided.
- the comb teeth 3 may be shaped to be provided with no intermediate portion 3 b by immediately reducing from the base 3 a toward the tip 3 d the diameter of the comb teeth 3 .
- the narrow portion 3 c reduces its diameter continuously from the intermediate portion 3 b in the form of a quadrangular pyramid with the tip 3 d as the vertex in FIG. 3( a ).
- the lateral cross sectional shape of the narrow portion 3 c is rectangular, it reduces the diameter so as to come closer to a right circle toward the tip 3 d.
- the lateral cross sectional shape of the narrow portion 3 c is not necessarily limited to a right circle. It may take a rectangular shape as in the case of FIG. 3( b ), or may take other shapes, such as a square, ellipses, and polygon.
- the tip 3 d is rounded off while being continual from the narrow portion 3 c and has a predetermined radius of curvature.
- the tip 3 d is located on the central axis in the side-by-side layout direction of the comb teeth 3 in FIG. 1 , it is not necessarily limited to the central axis, and may be located at an eccentric position.
- the tip 3 d may have a thick portion between the tip 3 d on the front side of the sheet in the front view of FIG. 3( b ), and the tip 3 d on the back side of the sheet therein.
- the radius of curvature of the tip 3 d is preferably in a range of 0.25 to 1.50 mm.
- the radius of curvature of the tip 3 d is less than 0.25 mm, the tip 3 d is too sharp, so that when the tip 3 d contact the head of a subject person, the subject person feels discomfort.
- the radius of curvature of the tip 3 d exceeds 1.50 mm, it is difficult to part the hair 6 efficiently.
- a length k of the tip portion 3 x is at least about 4.0 mm or greater. With the length k being less than 4.0 mm, the ratio of the length k of the narrow portion 3 c to the length s of the comb tooth 3 becomes smaller relatively, making it difficult to part the hair 6 .
- the lengths s of the comb teeth 3 can be set up individually. As shown in FIG. 1( a ), the lengths s of the comb teeth 3 may be set so that the length s of the comb tooth 3 _ 1 provided in the center portion of the support 2 becomes the longest. As shown in FIG. 1( a ), the lengths s of the other comb teeth 3 may be set to become shorter from the center portion of the support 2 toward the right and left ends thereof. Then, the lengths s of the comb teeth 3 _ 2 provided at the right and left ends of the support 2 may be set to become the shortest as shown in FIG. 1( a ).
- the positions of the bases 3 a are set to draw a gentle arc as a whole, as shown in FIG. 1( a ).
- the tip 3 d of the comb tooth 3 _ 2 is located slightly lower than the height at which the tips 3 d of the other comb teeth 3 are aligned in FIG. 1( a ). Accordingly, when the hair-dressing and cosmetic comb 1 contacts the head 5 of the subject person, the tip 3 d of the comb tooth 3 _ 2 can be prevented from damaging the head 5 and the cervical part of the subject person.
- the comb teeth 3 that the length s of the comb tooth 3 _ 1 ranges from 6.0 cm to 23.0 cm. It is also preferable that the length s of the comb tooth 3 _ 1 ranges from 10.0 cm to 20.0 cm. Especially the most preferred range of the length s of the comb tooth 3 _ 1 is between 12.0 cm and 17.0 cm. When the length s of the comb tooth 3 _ 1 is less than 6.0 cm, the comb teeth 3 cannot be elastically deformed sufficiently, and when the length s of the comb tooth 3 _ 1 exceeds 23.0 cm, there may be a case where the comb teeth 3 are caused to contact the head 5 of the subject person unnecessarily.
- the widths W of the comb teeth 3 are in a range of 1.0 to 12.0 mm.
- the widths W of the comb teeth 3 are less than 1.0 mm, the comb teeth 3 become too thin to have a sufficient strength as comb teeth and are difficult to manufacture.
- the widths W of the comb teeth 3 exceed 12.0 mm, the lengths to the upper parts of the comb teeth 3 through the gaps 4 of the comb teeth 3 become long, making it difficult to adequately part the hair 6 .
- the thicknesses H of the comb teeth 3 are in a range of 1.0 to 5.0 mm.
- the thicknesses H of the comb teeth 3 are less than 1.0 mm, the comb teeth 3 becomes too thin to have a sufficient strength as comb teeth.
- the thicknesses H of the comb teeth 3 exceed 5.0 mm, the comb teeth 3 become too thick, which may result in a case where large force is needed to deform the comb teeth 3 .
- the interval L can be set adequately, the range of 0 to 3.0 mm is desirable.
- adjacent comb teeth 3 are in contact with each other by a point or a line.
- the comb teeth 3 can be elastically deformed not only in the thickness direction of the comb teeth 3 but also in the side-by-side layout direction. Therefore, the portion where the interval L is 0 is widened from the tip sides of the comb teeth 3 by the hair 6 when the hair-dressing and cosmetic comb 1 is slid.
- the interval L exceeds 3.0 mm, the gap 4 between the adjacent comb teeth 3 becomes wider, making it difficult for the comb teeth 3 to catch the hair 6 .
- the contact surface M of adjacent comb teeth 3 may be formed by continuously providing the portion where the interval L is 0 by a fixed length as shown in FIG. 4 .
- the comb teeth 3 are urged in the direction of holding the hair 6 in the contact surface M due to the elastic force. Accordingly, the hair 6 can be caught firmly.
- the comb teeth 3 When the comb teeth 3 are deformed as shown in FIG. 12 , the comb teeth 3 have a maximum vertical height h from the horizontal plane P at the tip 3 d.
- the maximum vertical height h is set to be the amount of displacement of the tips 3 d from the horizontal plane P when the tips 3 d of the comb teeth 3 are deformed maximum upward or downward within the elastically deformable range of the comb teeth 3 with the hair-dressing and cosmetic comb 1 according to the invention set in the horizontal state.
- the maximum vertical height h is in a range of 0.5 cm to 6.0 cm. It is more preferable that the maximum vertical height h is in a range of 1.0 cm to 4.0 cm. When the maximum vertical height h is less than 0.5 cm, sufficient deformation cannot be obtained, disabling an efficient hairdressing and cosmetic work. When the maximum vertical height h exceeds 6.0 cm, there may be a case where the time for the comb teeth 3 to be restored by elastic deformation becomes long, making the working hours longer.
- the bending modulus of the comb-tooth member is in a range of 1.5 to 15.0 GPa.
- the bending modulus is less than 1.5 GPa, the comb teeth 3 becomes too soft, so that after the deformation, the time to be restored becomes longer.
- the bending modulus exceeds 15.0 GPa, it is necessary to change the shape of the comb, such as making the length s of the comb teeth 3 longer to deform the comb teeth 3 , so that the comb is difficult to handle.
- the raw material of the comb teeth 3 can be molded of synthetic resin integrally with the support 2 .
- synthetic resins polypropylene is an inexpensive raw material and generally, the bending modulus is set to about 1.5 GPa. Therefore, the material is suitable when industrially mass-producing the hair-dressing and cosmetic comb 1 according to the invention.
- the comb teeth 3 is not limited to a synthetic resin, and may be manufactured from wood, such as pine or Japan cedar, or other materials. Generally, the bending modulus of wood is set to about 5.0 to 16.0 GPa. When the comb-tooth material is wood, the massage effect brought about on the head 5 of the subject person, and the flexibility of wood can make the subject person relax more.
- a practitioner holds the hair-dressing and cosmetic comb 1 with all the comb teeth 3 aligned on the substantially the same plane in one hand, and puts the tips 3 d of the comb teeth 3 against the head 5 of the subject person before the position of the hair 6 to be cut or dyed. Then, the practitioner presses the comb teeth 3 toward the head 5 simultaneously to elastically deform almost all the comb teeth 3 . This operation causes the tip portions 3 x of almost all the comb teeth 3 to abut along the curved surface of the head 5 facing the comb teeth 3 as shown in FIG. 8 .
- the practitioner slides the whole hair-dressing and cosmetic comb 1 in the side-by-side layout direction of the comb teeth 3 while pressing the comb teeth 3 toward the head 5 , placing the hair 6 in the gaps 4 of the comb teeth 3 , as shown in FIG. 9 .
- the comb teeth 3 receives stress from the head 5 , and the individual comb teeth 3 are elastically deformed successively.
- an operation to slide the hair-dressing and cosmetic comb 1 along the curved shape of the head 5 may be carried out while placing the tip portions 3 x against the head 5 , as shown in FIG. 10( a ). Accordingly, the comb teeth 3 can be made to certainly contact with the base of the hair 6 to catch a lot of hair 6 .
- the practitioner parts the hair-dressing and cosmetic comb 1 from the head 5 , and lifts it up.
- This operation restores the comb teeth 3 to the state where all the comb teeth 3 are aligned on substantially the same plane by elastic deformation with the hair 6 still caught in the gaps 4 .
- the practitioner can efficiently perform the hairdressing and cosmetic work by cutting or dyeing the hair 6 caught in the comb teeth 3 with the scissors and dyeing instrument held in the other hand of the practitioner.
- the angle of the narrow portion 3 c to the central axis in the side-by-side layout direction of the comb teeth 3 becomes larger. Therefore, the distance between the tips 3 d of the adjacent comb teeth 3 becomes larger compared with the interval L of the comb teeth 3 . Therefore, the practitioner can part a lot of hair 6 . However, since there is a small contact surface between the tip 3 d and the head 5 , the subject person may feel discomfort when the tip 3 d abuts on the head 5 .
- the inventor conducted the following experiment 1 in order to clarify the optimal range of the radius of curvature of the tip 3 d.
- evaluations on the practitioner's workability were the degree of stress the practitioner felt in the work of parting the hair 6 when combing was performed with this hair-dressing and cosmetic comb 1 .
- the degree of stress was expressed in three levels, mark X when stress was felt even once, mark ⁇ when stress was not felt, and mark ⁇ when it felt comfortable.
- the evaluations from a subject person were the degree of discomfort the subject person felt when combed.
- the degree of discomfort was expressed in three levels, mark X when discomfort was felt even once, mark ⁇ when discomfort was not felt, and mark ⁇ when it was comfortable.
- the practitioner was a beautician having 30 years of experience, and the subject person was a woman of an age of twenties.
- the hair-dressing and cosmetic combs 1 used in the experiment were constituted as follows.
- the support 2 and the comb teeth 3 are integrally molded of polypropylene.
- the lateral cross sectional shape of the intermediate portion 3 b of the comb tooth 3 was approximately rectangular, with the width W and thickness H fixed.
- the narrow portion 3 c reduces its diameter in the form of a quadrangular pyramid with the tip 3 d as the vertex, and the lateral cross sectional shape of the narrow portion 3 c is rectangular, and reduces the diameter so as to come closer to a right circle toward the tip 3 d.
- the tip 3 d is rounded off.
- the lengths s of the comb teeth 3 _ 1 are set the longest to be about 15.0 cm.
- the lengths s of the other comb teeth 3 are set shorter horizontally symmetrically toward the right and left ends from the central portion of the support 2 , and the lengths s of the comb teeth 3 _ 2 on both the right and left sides are set to the same length of about 14.0 cm.
- the lengths s of the other comb teeth 3 are adjusted so that the tips 3 d of a plurality of comb teeth 3 are aligned approximately straight, as shown in FIG. 1( a ).
- the lengths s of the comb teeth 3 _ 2 are also adjusted so that their tips 3 d are set slightly lower than the positions of the tips of the other comb teeth 3 .
- the length k of the tip portion 3 x is about 1.8 cm.
- the widths W of the comb teeth 3 are about 6.0 mm, and the thicknesses H of the comb teeth 3 are about 4.0 mm.
- the intervals L of the comb teeth 3 are about 1.0 mm.
- Table 1 shows the results obtained from the experiment 1.
- the preferable range of the radius of curvature of the tip 3 d is 0.25 to 1.50 mm.
- the longer the lengths s of the comb teeth 3 the greater the comb teeth 3 are deformed by the practitioner with lighter force. If the lengths s of the comb teeth 3 are too long, the comb teeth 3 may be caused to unnecessarily contact the head 5 of the subject person.
- the inventor conducted the following experiments 2 in order to clarify the preferable range of the lengths s of the comb teeth 3 .
- the experiment of measuring the load was conducted as follows. First, the surface of a sphere with the radius of curvature of 9 cm was regarded as the head of a general adult, and the model of the sphere surface was created with a 2-cm-thick Japan cedar board, and was placed on a measuring instrument. The sphere model was graduated vertically. Then, the comb teeth 3 _ 1 were abutted on the top of the sphere model while the prepared comb was set in the horizontal state. Then, all of the tip portions 3 x of fifteen comb teeth were pushed vertically downward to abut on the sphere surface, and the load was applied until the positions of the right and left comb teeth 3 _ 2 came 1.5 cm below the comb teeth 3 _ 1 .
- evaluations on the practitioner's workability were the degree of stress the practitioner felt in handling the comb while performing the cutting work with this hair-dressing and cosmetic comb 1 .
- handling the comb the easiness of applying the load when the practitioner applied pressure, whether unnecessary contact with a cut wick was made, whether handling the comb was felt heavy, etc. were comprehensively judged to make evaluations.
- the degree of stress was expressed in four levels, mark X when stress was felt even once, mark ⁇ when stress was not felt, mark ⁇ when it felt comfortable, and mark ⁇ when it felt very comfortable.
- the practitioner was a beautician having 30 years of experience, and the cut wick used was a cut wick for lesson manufactured by Fontaine (FC108N).
- the hair-dressing and cosmetic combs 1 used in the experiment were constituted as follows.

Description
- 1. Field of the Invention
- The present invention relates to a hairdressing and cosmetic comb used mainly for cutting or dyeing hair, and hair-dressing and cosmetic method.
- 2. Description of the Related Art
- When a practitioner, such as a beautician or a barber, cuts hair, conventionally, the practitioner first combs hair using a comb (hereinafter called “combing”). Then, after performing combing several times, the practitioner cuts hair with scissors. When dyeing hair, likewise, hair is dyed after performing combing several times.
- For this reason, combs are demanded of the strengths large enough to endure the resistance at the time of combing hair, and proper shapes and weights easy for practitioners to handle. General combs have a plate-like shape as shown in
FIG. 12 , and have asupport 32 with an approximately rectangular shape in a front view,comb teeth 33 formed on one side thereof, and ahandle 34 provided continual from thesupport 32. Those combs are often made of synthetic resins, such as celluloid. - However, since the comb teeth of such a conventional comb are short and hard, the comb which abuts on a curved head shape comes in contact with the head in the form of a flat plate. Therefore, not all the comb teeth can contact the head at once. In addition, since the comb teeth are short, the quantity of hair which can be caught in the gaps of the comb teeth in single combing is restricted. For this reason, in a work of cutting or dyeing hair of the whole head, a practitioner needs to put the comb against the head many times and comb the hair repeatedly.
- In general, when a beautician cuts long hair, he/she parts the hair of a head into a required number of parts, and arranges hair part by part to make it easier to cut the hair before cutting (hereinafter called “blocking”). Then, the beautician performs combing several times with the comb held in one hand, and holds hair, caught by the comb teeth, between fingers of the other hand. Next, the beautician holds the comb with the other hand, and cuts the hair with scissors. This work requires that the beautician shifts the comb from one hand to another a number of times during cutting. In cutting the whole head hair of a child, for example, even a skilled beautician needs to shift the comb from one hand to another 30 to 40 times.
- When a practitioner cuts hair held with fingers just along the fingers, the cut lines may not be aligned in a straight line so that some adjustment should be done further. At this time, the practitioner may hurt his/her own fingers with scissors. In addition, since there is a small amount of hair which is cut in single cutting, a practitioner who is not familiar with the work has to take a check time many times during cutting to compare the finished image of the whole head with the current cut state in progress.
- In view of those points, in performing a cutting or dyeing work using a comb, a practitioner who is not a skilled one cannot perform efficiently the work.
- As a solution to such a problem, a cutting comb has been proposed in, for example,
Patent Document 1. The comb includes a parent comb and a child comb, so that hair combed with the parent comb is held by the comb teeth of the child comb to ensure shaping to the cutting expected position, allowing the hair to be cut with scissors as it is without changing fingers to hold the hair. -
- Japanese Unexamined Patent Publication No. Hei 10-28613
- However, the structure of the cutting comb requires the process of producing the parent comb and the child comb separately and then fitting them together, thus raising a problem of increasing the manufacturing cost.
- The area of the portion where the comb teeth of the cutting comb are provided is as small as the conventional one. Therefore, the amount of hair which can be caught in single combing is still small, raising a problem that it is not possible to efficiently perform a work of cutting or dyeing a large amount of hair of the whole head.
- Accordingly, it is an object of the invention to provide a hairdressing and cosmetic comb which catches a lot of hair in the gaps of the comb teeth in single combing, does not need blocking or shifting of the comb from one hand to another, allows hair to be aligned straight easily, allows a practitioner to image a finished state of the whole head without hurting fingers of the practitioner with scissors, ensures an efficient hairdressing and cosmetic work of cutting or dyeing, and is manufactured at low cost, and a hairdressing and cosmetic method using the comb.
- To achieve the object, a hairdressing and cosmetic comb according to the invention and a hairdressing and cosmetic method using the comb are configured as follows.
- According to a first aspect of the invention, there is provided a hairdressing and cosmetic comb, including a support; a plurality of comb teeth provided on one side of the support in a row substantially in parallel, the comb teeth each having lengths of 7.0 to 23.0 cm from a base to a tip and each being elastically bent and deformed to have a deformation of 1.0 cm or greater and 6.0 cm or less in a thickness direction of the comb teeth according to a form of a head when the comb teeth are pressed toward the head on which the comb teeth abut via a contact portion.
- According to a second aspect of the invention, in the hairdressing and cosmetic comb according to the first aspect of the invention, the comb teeth may have widths of 1.0 to 12.0 mm in a side-by-side layout direction of the comb teeth, and thicknesses of 1.0 to 5.0 mm.
- According to a third aspect of the invention, in the hairdressing and cosmetic comb according to the first or second aspect of the invention, a sectional shape of each of the comb teeth in the side-by-side layout direction of the comb teeth may be a rectangle defined by W>H where W mm is the width in the side-by-side layout direction of the comb teeth and H mm is the thickness of the comb teeth. Therefore, the long sides of the rectangles of the comb teeth in cross section abut on the head.
- According to a fourth aspect of the invention, in the hairdressing and cosmetic comb according to any one of the first to third aspects of the invention, the widths of the comb teeth in the side-by-side layout direction thereof may be constant at an intermediate portion from the base of each comb tooth to the tip thereof.
- According to a fifth aspect of the invention, in the hairdressing and cosmetic comb according to any one of the first to fourth aspects of the invention, the lengths of the plurality of comb teeth from the bases to the tips may be set in such a way that the length of the comb tooth provided at a center portion of the support is longest, and the lengths of the other comb teeth become shorter toward rightward and leftward end portions of the support from the center portion. Accordingly, the comb teeth provided in the center portion of the support deform more than the other comb teeth. Relatively speaking, the comb teeth which are provided apart from the center portion of the support deform less than the comb teeth which are provided in the center portion of the support.
- According to a sixth aspect of the invention, in the hairdressing and cosmetic comb according to any one of the first to fifth aspects of the invention, an interval of the comb teeth may be less than 0 to 3.0 mm.
- According to a seventh aspect of the invention, in the hairdressing and cosmetic comb according to any one of the first to sixth aspects of the invention, the comb teeth may be made of a synthetic resin, and may have the widths of about 6.0 mm in the side-by-side layout direction thereof, and the thicknesses of about 4.0 mm, and an interval of the comb teeth may be about 1.0 mm.
- According to an eighth aspect of the invention, in the hairdressing and cosmetic comb according to any one of the first to sixth aspects of the invention, at least one contact surface at which the adjoining comb teeth contact each other may be formed in the interval between the comb teeth and between the base and the tip of each comb tooth.
- According to a ninth aspect of the invention, in the hairdressing and cosmetic comb according to any one of the first to eighth aspects of the invention, the comb teeth may be bent in the thickness direction of the comb teeth.
- A hairdressing and cosmetic method according to a tenth aspect of the invention includes abutting the comb teeth of the hairdressing and cosmetic comb according to any one of the first to ninth aspects of the invention on a head; sliding the hairdressing and cosmetic comb while pressing a contact portion toward the head to put through hair of the head between the comb teeth to elastically deform the comb teeth according to a form of the head, thereby combing the hair for hair-dressing and cosmetic work.
- According to the invention, hair can be caught in the gaps between almost all comb teeth, including the comb teeth provided at end portions of the support as well as the comb teeth provided in the center portion of the support.
- According to the invention, a practitioner can shorten the time of a hairdressing and cosmetic work.
- According to the invention, a practitioner need not apply large force to slide the comb. In addition, the comb can be designed in an easy-to-handle shape.
- According to the invention, since the comb teeth stably receive stress while being pressed to slide toward the head, a practitioner can slide the hairdressing and cosmetic comb smoothly. When hair is put between the comb teeth, the area of the opposing sides of the adjoining comb teeth where the comb teeth contact the hair can be enlarged. This can allow hair to be firmly caught between the comb teeth.
- According to the invention, it is possible to improve the fatigue durability of the comb teeth which are repeatedly elastically deformed, and easily manufacture comb teeth.
- According to the invention, it is easy to greatly bend the comb teeth provided in the center section of the support. Accordingly, the comb teeth can be easily pressed against the curved shape of a head.
- According to the invention, a practitioner can easily place the comb teeth of the hairdressing and cosmetic comb against the curved shape of a head and easily slide the comb teeth.
- Because of the foregoing structure of the hairdressing and cosmetic comb and the process of the hairdressing and cosmetic method using the comb, a practitioner can catch more hair with the comb teeth than can be done conventionally. In addition, hair can be firmly caught as well as can be combed with the comb teeth. Accordingly, since a practitioner can perform a hairdressing and cosmetic work with a lot of hair caught with the comb teeth, he/she need not perform blocking or shift the comb from one hand to another. In cutting hair, a practitioner does not easily damage his/her own fingers with scissors, and can easily cut hair straight. Further, it is easy to compare the finished image of the whole head with the current state of the work in progress.
- Therefore, the practitioner can improve the efficiency of the whole hairdressing and cosmetic work by using the hairdressing and cosmetic comb and the hairdressing and cosmetic method using the comb to which the invention is applied. Since the operation of the comb teeth is simple, the practitioner can handle the comb easily, so that even a non-expert practitioner can use this hairdressing and cosmetic comb. Further, because of its comparatively simple structure, the hairdressing and cosmetic comb can be mass-produced at a low cost.

FIG. 1( a) is a front view of a hairdressing andcosmetic comb 1 according to the invention,FIG. 1( b) is a plan view of the hairdressing andcosmetic comb 1 according to the invention,FIG. 1( c) is a bottom view of the hairdressing andcosmetic comb 1 according to the invention, andFIG. 1( d) is a right side view of the hairdressing andcosmetic comb 1 according to the invention. - As shown in
FIG. 1( a), the hairdressing andcosmetic comb 1 according to the invention includes asupport 2 and a plurality ofcomb teeth 3. - The
support 2 has asupport surface 2 a on the front side of the sheet inFIG. 1( a), and asupport surface 2 b on the rear side of the sheet inFIG. 1( a) and facing thesupport surface 2 a. As shown inFIG. 1( d), thesupport 2 has aright side portion 2 d. Thesupport 2 also has aleft side portion 2 e facing theright side portion 2 d. As shown inFIG. 1( c), thesupport 2 has abottom surface portion 2 c, thecomb teeth 3 are provided on that side which faces thebottom surface portion 2 c, and thesupport 2 is continual tobases 3 a of thecomb teeth 3. - As shown in
FIG. 2( a), thesupport 2 may have a form such that the right and leftside portions comb teeth 3. Further, as shown inFIG. 2( b), projectingend portions 2 f may be formed by reducing the diameter of thesupport 2 once and then enlarging it toward thebottom surface portion 2 c. - The thickness of the
support 2 is substantially the same thickness H of thecomb teeth 3 inFIG. 1 , but should not necessarily be substantially the same thickness. The thickness of thesupport 2 may be thicker or thinner than the thickness H of thecomb teeth 3, and may be partly thicker or thinner than the thickness H of thecomb teeth 3. As shown inFIG. 2( c), a hand-holdingportion 2 g protruded or recessed on thesupport surface - As shown in
FIG. 2( d), athin teeth portion 2 h may be provided at one or both of the right and leftside portions thin teeth portion 2 h are short and hard, and are not therefore elastically deformed like thecomb teeth 3. A practitioner can perform a hairdressing and cosmetic work on thewhole head 5 using thecomb teeth 3, and perform a hairdressing and cosmetic work on a detailed portion using thethin teeth portion 2 h. - As shown in
FIG. 2( e), ahandle 2 i may be provided at one of the right and leftside portions handle 2 i makes it easier for the practitioner to press the hairdressing andcosmetic comb 1. - As shown in
FIG. 2( f), combteeth 3 which are different from thecomb teeth 3 which catchhair 6 may be provided on thebottom surface portion 2 c side. As shown inFIG. 2( f), a length s of thecomb teeth 3 on thebottom surface portion 2 c side is comparatively short, and an interval L of thecomb teeth 3 is comparatively long. The width, W, and thickness, H, of thecomb teeth 3 on thebottom surface portion 2 c side may be set adequately. When thetarget hair 6 is disheveled, the practitioner can perform combing generally with thesecomb teeth 3 on thebottom surface portion 2 c side before cutting or dyeing thehair 6 to arrange the flow of thehair 6. - The
support 2 can be molded of a synthetic resin, such as polypropylene or epoxy resin, integrally with thecomb teeth 3 to be described later. However, the raw material of thesupport 2 is not limited to a synthetic resin, and other materials, such as wood and metal, may be used as well. - The
comb teeth 3 are provided in a row substantially in parallel to one another withgaps 4 therebetween, as shown inFIG. 1( a). Although the number of thecomb teeth 3 is 15 inFIG. 1( a), which is not necessarily restrictive and may be set to any adequate number. -
FIG. 3( a) is a diagram showing one form of the tip side of thecomb tooth 3.FIG. 3( b) is a diagram showing another form of the tip side of thecomb tooth 3. In each diagram, the left-hand side shows a front view, and the right-hand side shows a right side view. - The
comb tooth 3 has, between a base 3 a and atip 3 d, anintermediate portion 3 b and anarrow portion 3 c whose diameter gradually decreases from theintermediate portion 3 b, as shown inFIG. 1 andFIG. 3( a). - Note that the
base 3 a is the boundary portion between thesupport 2 and thecomb teeth 3 hereinafter. Unless specifically defined, the length s of the comb teeth indicates the length from thebase 3 a to thetip 3 d hereinafter. Unless specifically defined, thetip portion 3 x is the portion which includes thenarrow portion 3 c and thetip 3 d hereinafter. - Although the
intermediate portion 3 b is formed linearly in the side-by-side layout direction of thecomb teeth 3 inFIG. 1( a), it is not necessarily limited to the linear shape. A part of theintermediate portion 3 b may be curved in the side-by-side layout direction so that an interval L of thegap 4 on thebase 3 a side is different from an interval L of thegap 4 on thetip portion 3 x side, as shown inFIG. 5 . Accordingly, when thehair 6 is put through thegaps 4 which have the relatively shorter interval L, the presence of thegaps 4 which has the relatively longer interval L on thebase 3 a side makes it easier to feed thehair 6 toward thebase 3 a from thetip portion 3 x side of thecomb teeth 3. When theadjacent comb teeth 3 which form thegap 4 having the relatively shorter interval L are elastically deformed in the side-by-side layout direction of thecomb teeth 3 by catchingmuch hair 6, the elastic force urges thosecomb teeth 3 in the direction of holding thehair 6. Accordingly, thecomb teeth 3 can catch thehair 6 firmly. - As shown in
FIG. 7( b), theintermediate portion 3 b may be curved in the thickness direction of thecomb teeth 3, or may be bent at a proper location in addition. The curved shapes of a plurality of comb teeth provided on one comb may match with, or may differ from, one another. The curved shape of theintermediate portion 3 b may be an arc, an elliptic arc, or a hyperbola. In case of the arcuate shape, it is desirable that the radius of curvature is in the range of 5.0 to 10.0 cm. Within the range, the comb can be compatible with the radiuses of curvature of general human heads covering from children to adults, and are suitable as a hair-dressing and cosmetic comb. - As shown in
FIG. 12 , the lateral cross sectional shape of theintermediate portion 3 b is approximately rectangular. However, the sectional shape of theintermediate portion 3 b may not be limited to the approximately rectangular shape, and may take another shape, such as approximately circular shape, approximately elliptical shape, or polygonal shape. InFIG. 1 , the width W and thickness H of theintermediate portion 3 b is constant from thebase 3 a to thenarrow portion 3 c. However, a portion with a partly larger width W or a portion with a partly narrower width W may be provided, and a portion with a partly larger thickness H or a portion with a partly smaller thickness H may be provided. Further, thecomb teeth 3 may be shaped to be provided with nointermediate portion 3 b by immediately reducing from thebase 3 a toward thetip 3 d the diameter of thecomb teeth 3. - The
narrow portion 3 c reduces its diameter continuously from theintermediate portion 3 b in the form of a quadrangular pyramid with thetip 3 d as the vertex inFIG. 3( a). Although the lateral cross sectional shape of thenarrow portion 3 c is rectangular, it reduces the diameter so as to come closer to a right circle toward thetip 3 d. However, the lateral cross sectional shape of thenarrow portion 3 c is not necessarily limited to a right circle. It may take a rectangular shape as in the case ofFIG. 3( b), or may take other shapes, such as a square, ellipses, and polygon. - The
tip 3 d is rounded off while being continual from thenarrow portion 3 c and has a predetermined radius of curvature. Although thetip 3 d is located on the central axis in the side-by-side layout direction of thecomb teeth 3 inFIG. 1 , it is not necessarily limited to the central axis, and may be located at an eccentric position. - As shown in the right-hand side view of
FIG. 3( b), thetip 3 d may have a thick portion between thetip 3 d on the front side of the sheet in the front view ofFIG. 3( b), and thetip 3 d on the back side of the sheet therein. - The radius of curvature of the
tip 3 d is preferably in a range of 0.25 to 1.50 mm. When the radius of curvature of thetip 3 d is less than 0.25 mm, thetip 3 d is too sharp, so that when thetip 3 d contact the head of a subject person, the subject person feels discomfort. When the radius of curvature of thetip 3 d exceeds 1.50 mm, it is difficult to part thehair 6 efficiently. - It is desirable that a length k of the
tip portion 3 x is at least about 4.0 mm or greater. With the length k being less than 4.0 mm, the ratio of the length k of thenarrow portion 3 c to the length s of thecomb tooth 3 becomes smaller relatively, making it difficult to part thehair 6. - The lengths s of the
comb teeth 3 can be set up individually. As shown inFIG. 1( a), the lengths s of thecomb teeth 3 may be set so that the length s of the comb tooth 3_1 provided in the center portion of thesupport 2 becomes the longest. As shown inFIG. 1( a), the lengths s of theother comb teeth 3 may be set to become shorter from the center portion of thesupport 2 toward the right and left ends thereof. Then, the lengths s of the comb teeth 3_2 provided at the right and left ends of thesupport 2 may be set to become the shortest as shown inFIG. 1( a). - When the
comb teeth 3 with different lengths s are provided on thesupport 2 to have therespective tips 3 d aligned approximately horizontally straight, the positions of thebases 3 a are set to draw a gentle arc as a whole, as shown inFIG. 1( a). Thetip 3 d of the comb tooth 3_2 is located slightly lower than the height at which thetips 3 d of theother comb teeth 3 are aligned inFIG. 1( a). Accordingly, when the hair-dressing andcosmetic comb 1 contacts thehead 5 of the subject person, thetip 3 d of the comb tooth 3_2 can be prevented from damaging thehead 5 and the cervical part of the subject person. - It is preferable that the
comb teeth 3 that the length s of the comb tooth 3_1 ranges from 6.0 cm to 23.0 cm. It is also preferable that the length s of the comb tooth 3_1 ranges from 10.0 cm to 20.0 cm. Especially the most preferred range of the length s of the comb tooth 3_1 is between 12.0 cm and 17.0 cm. When the length s of the comb tooth 3_1 is less than 6.0 cm, thecomb teeth 3 cannot be elastically deformed sufficiently, and when the length s of the comb tooth 3_1 exceeds 23.0 cm, there may be a case where thecomb teeth 3 are caused to contact thehead 5 of the subject person unnecessarily. - When the length s of the comb tooth 3_1 is set to 6.0 to 23.0 cm, it is preferable that the widths W of the
comb teeth 3 are in a range of 1.0 to 12.0 mm. When the widths W of thecomb teeth 3 are less than 1.0 mm, thecomb teeth 3 become too thin to have a sufficient strength as comb teeth and are difficult to manufacture. When the widths W of thecomb teeth 3 exceed 12.0 mm, the lengths to the upper parts of thecomb teeth 3 through thegaps 4 of thecomb teeth 3 become long, making it difficult to adequately part thehair 6. - When the length s of the comb tooth 3_1 is set to 6.0 to 23.0 cm, it is preferable that the thicknesses H of the
comb teeth 3 are in a range of 1.0 to 5.0 mm. When the thicknesses H of thecomb teeth 3 are less than 1.0 mm, thecomb teeth 3 becomes too thin to have a sufficient strength as comb teeth. When the thicknesses H of thecomb teeth 3 exceed 5.0 mm, thecomb teeth 3 become too thick, which may result in a case where large force is needed to deform thecomb teeth 3. - Although the interval L can be set adequately, the range of 0 to 3.0 mm is desirable. When the interval L is 0,
adjacent comb teeth 3 are in contact with each other by a point or a line. Thecomb teeth 3 can be elastically deformed not only in the thickness direction of thecomb teeth 3 but also in the side-by-side layout direction. Therefore, the portion where the interval L is 0 is widened from the tip sides of thecomb teeth 3 by thehair 6 when the hair-dressing andcosmetic comb 1 is slid. When the interval L exceeds 3.0 mm, thegap 4 between theadjacent comb teeth 3 becomes wider, making it difficult for thecomb teeth 3 to catch thehair 6. - The contact surface M of
adjacent comb teeth 3 may be formed by continuously providing the portion where the interval L is 0 by a fixed length as shown inFIG. 4 . When thehair 6 is put in the contact surface M, thecomb teeth 3 are urged in the direction of holding thehair 6 in the contact surface M due to the elastic force. Accordingly, thehair 6 can be caught firmly. - When the
comb teeth 3 are deformed as shown inFIG. 12 , thecomb teeth 3 have a maximum vertical height h from the horizontal plane P at thetip 3 d. The maximum vertical height h is set to be the amount of displacement of thetips 3 d from the horizontal plane P when thetips 3 d of thecomb teeth 3 are deformed maximum upward or downward within the elastically deformable range of thecomb teeth 3 with the hair-dressing andcosmetic comb 1 according to the invention set in the horizontal state. - It is preferable that the maximum vertical height h is in a range of 0.5 cm to 6.0 cm. It is more preferable that the maximum vertical height h is in a range of 1.0 cm to 4.0 cm. When the maximum vertical height h is less than 0.5 cm, sufficient deformation cannot be obtained, disabling an efficient hairdressing and cosmetic work. When the maximum vertical height h exceeds 6.0 cm, there may be a case where the time for the
comb teeth 3 to be restored by elastic deformation becomes long, making the working hours longer. - It is preferable that the bending modulus of the comb-tooth member is in a range of 1.5 to 15.0 GPa. When the bending modulus is less than 1.5 GPa, the
comb teeth 3 becomes too soft, so that after the deformation, the time to be restored becomes longer. When the bending modulus exceeds 15.0 GPa, it is necessary to change the shape of the comb, such as making the length s of thecomb teeth 3 longer to deform thecomb teeth 3, so that the comb is difficult to handle. - The raw material of the
comb teeth 3 can be molded of synthetic resin integrally with thesupport 2. Of synthetic resins, polypropylene is an inexpensive raw material and generally, the bending modulus is set to about 1.5 GPa. Therefore, the material is suitable when industrially mass-producing the hair-dressing andcosmetic comb 1 according to the invention. - The
comb teeth 3 is not limited to a synthetic resin, and may be manufactured from wood, such as pine or Japan cedar, or other materials. Generally, the bending modulus of wood is set to about 5.0 to 16.0 GPa. When the comb-tooth material is wood, the massage effect brought about on thehead 5 of the subject person, and the flexibility of wood can make the subject person relax more. - Next, how to use the hair-dressing and
cosmetic comb 1 to which the invention is applied will be described. - First, a practitioner holds the hair-dressing and
cosmetic comb 1 with all thecomb teeth 3 aligned on the substantially the same plane in one hand, and puts thetips 3 d of thecomb teeth 3 against thehead 5 of the subject person before the position of thehair 6 to be cut or dyed. Then, the practitioner presses thecomb teeth 3 toward thehead 5 simultaneously to elastically deform almost all thecomb teeth 3. This operation causes thetip portions 3 x of almost all thecomb teeth 3 to abut along the curved surface of thehead 5 facing thecomb teeth 3 as shown inFIG. 8 . - Next, the practitioner slides the whole hair-dressing and
cosmetic comb 1 in the side-by-side layout direction of thecomb teeth 3 while pressing thecomb teeth 3 toward thehead 5, placing thehair 6 in thegaps 4 of thecomb teeth 3, as shown inFIG. 9 . According to this operation, thecomb teeth 3 receives stress from thehead 5, and theindividual comb teeth 3 are elastically deformed successively. - Here, an operation to slide the hair-dressing and
cosmetic comb 1 along the curved shape of thehead 5 may be carried out while placing thetip portions 3 x against thehead 5, as shown inFIG. 10( a). Accordingly, thecomb teeth 3 can be made to certainly contact with the base of thehair 6 to catch a lot ofhair 6. - As shown in
FIG. 10( b), an operation to slide the hair-dressing andcosmetic comb 1 linearly with theintermediate portion 3 b abutting on thehead 5 as a contact portion. That is, the position at which thecomb teeth 3 receive stress moves to theintermediate portion 3 b from thetip portion 3 x, and further moves to thebase 3 a in theintermediate portion 3 b. Accordingly, compared with the case ofFIG. 10( a), the time needed for single combing can be shortened. - Finally, as shown in
FIG. 11 , the practitioner parts the hair-dressing andcosmetic comb 1 from thehead 5, and lifts it up. This operation restores thecomb teeth 3 to the state where all thecomb teeth 3 are aligned on substantially the same plane by elastic deformation with thehair 6 still caught in thegaps 4. Then, the practitioner can efficiently perform the hairdressing and cosmetic work by cutting or dyeing thehair 6 caught in thecomb teeth 3 with the scissors and dyeing instrument held in the other hand of the practitioner. - When the radius of curvature of the
tip 3 d becomes smaller with the widths W and lengths k of thecomb teeth 3 being fixed, the angle of thenarrow portion 3 c to the central axis in the side-by-side layout direction of thecomb teeth 3 becomes larger. Therefore, the distance between thetips 3 d of theadjacent comb teeth 3 becomes larger compared with the interval L of thecomb teeth 3. Therefore, the practitioner can part a lot ofhair 6. However, since there is a small contact surface between thetip 3 d and thehead 5, the subject person may feel discomfort when thetip 3 d abuts on thehead 5. On the contrary, when the radius of curvature of thetip 3 d becomes larger, the angle of thenarrow portion 3 c to the central axis in the side-by-side layout direction of thecomb teeth 3 becomes smaller. Therefore, the distance between thetips 3 d of theadjacent comb teeth 3 approaches the interval L of thecomb teeth 3. Therefore, the practitioner cannot part a lot ofhair 6 relatively. However, since there is a large contact surface between thetip 3 d and thehead 5, the subject person is unlikely to feel discomfort when thetip 3 d abuts on the subject person. - Accordingly, the inventor conducted the
following experiment 1 in order to clarify the optimal range of the radius of curvature of thetip 3 d. - In the
experiment 1, ten kinds ofcomb teeth 3 which have thetips 3 d with different radiuses of curvature of 0.05 to 2.00 mm were manufactured, and the hair-dressing andcosmetic combs 1 provided with thosecomb teeth 3 were prepared. When cutting was performed using this hair-dressing andcosmetic comb 1, the practitioner who did cutting and the subject person who had hair cut were interviewed to acquire evaluations on the workability of the practitioner and evaluations from the subject person. - Here, evaluations on the practitioner's workability were the degree of stress the practitioner felt in the work of parting the
hair 6 when combing was performed with this hair-dressing andcosmetic comb 1. Specifically, the degree of stress was expressed in three levels, mark X when stress was felt even once, mark Δ when stress was not felt, and mark ◯ when it felt comfortable. The evaluations from a subject person were the degree of discomfort the subject person felt when combed. Specifically, the degree of discomfort was expressed in three levels, mark X when discomfort was felt even once, mark Δ when discomfort was not felt, and mark ◯ when it was comfortable. The practitioner was a beautician having 30 years of experience, and the subject person was a woman of an age of twenties. - The hair-dressing and
cosmetic combs 1 used in the experiment were constituted as follows. - The
support 2 and thecomb teeth 3 are integrally molded of polypropylene. The lateral cross sectional shape of theintermediate portion 3 b of thecomb tooth 3 was approximately rectangular, with the width W and thickness H fixed. Thenarrow portion 3 c reduces its diameter in the form of a quadrangular pyramid with thetip 3 d as the vertex, and the lateral cross sectional shape of thenarrow portion 3 c is rectangular, and reduces the diameter so as to come closer to a right circle toward thetip 3 d. Thetip 3 d is rounded off. The lengths s of the comb teeth 3_1 are set the longest to be about 15.0 cm. The lengths s of theother comb teeth 3 are set shorter horizontally symmetrically toward the right and left ends from the central portion of thesupport 2, and the lengths s of the comb teeth 3_2 on both the right and left sides are set to the same length of about 14.0 cm. The lengths s of theother comb teeth 3 are adjusted so that thetips 3 d of a plurality ofcomb teeth 3 are aligned approximately straight, as shown inFIG. 1( a). The lengths s of the comb teeth 3_2 are also adjusted so that theirtips 3 d are set slightly lower than the positions of the tips of theother comb teeth 3. The length k of thetip portion 3 x is about 1.8 cm. The widths W of thecomb teeth 3 are about 6.0 mm, and the thicknesses H of thecomb teeth 3 are about 4.0 mm. The intervals L of thecomb teeth 3 are about 1.0 mm. - Table 1 shows the results obtained from the
experiment 1. -
TABLE 1 Curvature radius of tip (mm) 0.05 0.15 0.25 0.35 0.50 1.00 1.50 1.65 1.75 2.00 Evaluation on x x Δ ∘ ∘ ∘ Δ x x x workability (in 3 levels) Evaluation x x Δ ∘ ∘ ∘ ∘ ∘ ∘ ∘ from subject (in 3 levels) - It can be confirmed from Table 1 that when the radius of curvature of the
tip 3 d is in a range of 0.25 to 1.50 mm, the evaluations on the practitioner's workability are Δ and ◯. When the radius of curvature of thetip 3 d is 0.25 mm or higher, it can be confirmed that the evaluations from the subject person are Δ and ◯. - It is understood from the above that under the conditions of this experiment, the preferable range of the radius of curvature of the
tip 3 d is 0.25 to 1.50 mm. - When it is necessary to acquire a predetermined maximum vertical height h, given that the conditions other than the lengths s of the
comb teeth 3 are fixed, the longer the lengths s of thecomb teeth 3, the greater thecomb teeth 3 are deformed by the practitioner with lighter force. If the lengths s of thecomb teeth 3 are too long, thecomb teeth 3 may be caused to unnecessarily contact thehead 5 of the subject person. - Accordingly, the inventor conducted the following
experiments 2 in order to clarify the preferable range of the lengths s of thecomb teeth 3. - In the
experiment 2, twenty kinds of hair-dressing andcosmetic combs 1 with different lengths s of the comb teeth 3_1 ranging from 5.0 to 24.0 cm were prepared. Then, the load (g.w.) required to obtain the maximum vertical height h=1.5 (cm) was measured, and evaluations were made on the workability of the practitioner who performed cutting when the cutting work was performed using this hair-dressing andcosmetic comb 1. - The experiment of measuring the load was conducted as follows. First, the surface of a sphere with the radius of curvature of 9 cm was regarded as the head of a general adult, and the model of the sphere surface was created with a 2-cm-thick Japan cedar board, and was placed on a measuring instrument. The sphere model was graduated vertically. Then, the comb teeth 3_1 were abutted on the top of the sphere model while the prepared comb was set in the horizontal state. Then, all of the
tip portions 3 x of fifteen comb teeth were pushed vertically downward to abut on the sphere surface, and the load was applied until the positions of the right and left comb teeth 3_2 came 1.5 cm below the comb teeth 3_1. - Here, evaluations on the practitioner's workability were the degree of stress the practitioner felt in handling the comb while performing the cutting work with this hair-dressing and
cosmetic comb 1. With regard to handling the comb, the easiness of applying the load when the practitioner applied pressure, whether unnecessary contact with a cut wick was made, whether handling the comb was felt heavy, etc. were comprehensively judged to make evaluations. Specifically, the degree of stress was expressed in four levels, mark X when stress was felt even once, mark Δ when stress was not felt, mark ◯ when it felt comfortable, and mark ⊚ when it felt very comfortable. The practitioner was a beautician having 30 years of experience, and the cut wick used was a cut wick for lesson manufactured by Fontaine (FC108N). - The hair-dressing and
cosmetic combs 1 used in the experiment were constituted as follows. - The
support 2 and thecomb teeth 3 are integrally molded of polypropylene. The lateral cross sectional shape of theintermediate portion 3 b of thecomb tooth 3 was approximately rectangular, with the width W and thickness H fixed. Thenarrow portion 3 c reduces its diameter in the form of a quadrangular pyramid with thetip 3 d as the vertex, and the lateral cross sectional shape of thenarrow portion 3 c is rectangular, and reduces the diameter so as to come closer to a right circle toward thetip 3 d. Thetip 3 d is rounded off to have a radius of curvature of about 0.90 mm. The lengths s of the comb teeth 3_1 are set the longest. The lengths s of theother comb teeth 3 are set shorter horizontally symmetrically toward the right and left ends from the central portion of thesupport 2. The lengths s of theother comb teeth 3 are adjusted so that thetips 3 d of a plurality ofcomb teeth 3 are aligned approximately straight, as shown inFIG. 1( a). The lengths s of the comb teeth 3_2 are also adjusted so that theirtips 3 d are set slightly lower than the positions of the tips of theother comb teeth 3. The lengths s of the comb teeth 3_2 are set shorter than the lengths of the comb teeth 3_1 by about 1.0 cm, and are set the same on both the right and left sides. The length k of thetip portion 3 x is about 1.8 cm. The widths W of thecomb teeth 3 are about 6.0 mm, and the thicknesses H of thecomb teeth 3 are about 4.0 mm. The intervals L of thecomb teeth 3 are about 1.0 mm. - Table 2 shows the results obtained from the
experiment 2. -
TABLE 2 Length of comb tooth 5.0 6.0 7.0 8.0 9.0 3_1 (cm) Necessary load (g.w.) 5,000 3,000 2,000 1,300 1,100 Evaluation on work- X X Δ Δ Δ ability (in 3 levels) Length of comb tooth 10.0 11.0 12.0 13.0 14.0 3_1 (cm) Necessary load (g.w.) 850 700 500 350 300 Evaluation on work- ◯ ◯ ⊚ ⊚ ⊚ ability (in 3 levels) Length of comb tooth 15.0 16.0 17.0 18.0 19.0 3_1 (cm) Necessary load (g.w.) 250 180 150 120 110 Evaluation on work- ⊚ ⊚ ⊚ ◯ ◯ ability (in 3 levels) Length of comb tooth 20.0 21.0 22.0 23.0 24.0 3_1 (cm) Necessary load (g.w.) 100 88 75 65 50 Evaluation on work- ◯ Δ Δ Δ X ability (in 3 levels) - It can be confirmed from Table 2 that when the lengths s of the comb teeth 3_1 are in a range of 7.0 to 23.0 cm, a load of about 65 to about 2000 g.w. is needed. It can also be confirmed that the evaluations on the workability of the practitioner are Δ, ◯ and ⊚.
- When the lengths s of the comb teeth 3_1 are in a range of 10.0 to 20.0 cm, it can be confirmed that a load of about 100 g.w. to about 850 g.w. is needed. It can also be confirmed that the evaluations of the practitioner are ◯ and ⊚.
- When the lengths s of the comb teeth 3_1 are in a range of 12.0 to 17.0 cm, it can be confirmed that a load of about 150 g.w. to about 500 g.w. is needed. It can also be confirmed that the evaluations of the practitioner are ⊚.
- It is understood from the above that under the conditions of this experiment, the preferable range of the lengths s of the comb teeth 3_1 is 7.0 to 23.0 mm.
- When the conditions other than the radius of curvature of the member of the
comb teeth 3 are fixed, the smaller the radius of curvature is, the greater the maximum vertical height h of thecomb teeth 3 becomes. Therefore, the practitioner can deform thecomb teeth 3 greatly with lighter force. However, the time for thecomb teeth 3 to revert to the initial state by elastic deformation becomes longer. On the contrary, the greater the radius of curvature is, the smaller the maximum vertical height h of thecomb teeth 3 becomes. Therefore, the practitioner needs larger force to deform thecomb teeth 3. However, the time for thecomb teeth 3 to revert to the initial state by elastic deformation becomes shorter. - In this respect, the inventor conducted the
following experiment 3 to clarify the preferable range of the maximum vertical height h of thecomb teeth 3. - In the
experiment 3, six kinds of hair-dressing andcosmetic combs 1 whosecomb teeth 3 have different maximum vertical heights h of 0.0 to 6.0 cm were prepared. Then, the work time in performing a predetermined cutting work using the hair-dressing andcosmetic comb 1 was checked. The practitioner was a beautician having 30 years of experience, and the cut model used was a cut wick for lesson manufactured by Fontaine (FC108N). The cut style was the square cut to cut thehair 6 of the top portion of the head by about 10 cm. A work time (minutes) of less than one minute was rounded up. - The hair-dressing and
cosmetic combs 1 used in the experiment were constituted as follows. - The lateral cross sectional shape of the
intermediate portion 3 b of thecomb tooth 3 was approximately rectangular, with the width W and thickness H fixed. Thenarrow portion 3 c reduces its diameter in the form of a quadrangular pyramid with thetip 3 d as the vertex, and the lateral cross sectional shape of thenarrow portion 3 c is rectangular, and reduces the diameter so as to come closer to a right circle toward thetip 3 d. Thetip 3 d is rounded off to have a radius of curvature of about 0.90 mm. The lengths s of the comb teeth 3_1 are set the longest to be about 15.0 cm. The lengths s of theother comb teeth 3 are set shorter horizontally symmetrically toward the right and left ends from the central portion of thesupport 2, and the lengths s of the comb teeth 3_2 on both the right and left sides are set to the same length of about 14.0 cm. The lengths s of theother comb teeth 3 are adjusted so that thetips 3 d of a plurality ofcomb teeth 3 are aligned approximately straight, as shown inFIG. 1( a). The lengths s of the comb teeth 3_2 are also adjusted so that theirtips 3 d are set slightly lower than the positions of the tips of theother comb teeth 3. The length k of thetip portion 3 x is about 1.8 cm. The widths W of thecomb teeth 3 are about 6.0 mm, and the thicknesses H of thecomb teeth 3 are about 4.0 mm. The intervals L of thecomb teeth 3 are about 1.0 mm. In the table, thecomb teeth 3 with h of 0.0 to 1.0 are made of wood, and thecomb teeth 3 with h of 2.0 to 6.0 are made of an epoxy resin, so that those comb teeth have different elastic moduli. Accordingly, the maximum vertical height h of the individual types ofcomb teeth 3 was changed. - Table 3 shows the results obtained from this
experiment 3. -
TABLE 3 Vertical height h(cm) 0.0 0.5 1.0 2.0 4.0 6.0 Work time 20 15 10 5 10 15 (min) - It can be confirmed from Table 3 that when the maximum vertical height h of the
comb teeth 3 is in a range of 0.5 to 6.0 cm, the work time is less than about 15 minutes. It can also be confirmed that when the maximum vertical height h of thecomb teeth 3 is in a range of 1.0 to 4.0 cm, the work time is less than about 10 minutes. It can also be confirmed that when the maximum vertical height h of thecomb teeth 3 is about 2.0 cm, the work time is about 5 minutes and the shortest. - It is understood from the above that under conditions of this experiment, the preferable range of the maximum vertical height h of the
comb teeth 3 is 0.5 to 6.0 cm. -
