Description

Description HAIR REMOVING DEVICE

Technical Field

[1] The present invention relates to a hair removing device for plucking various downy hairs and warts from the skin, and more particularly to a hair removing device, in which when a pair of levers is alternately spread out and closed up repeatedly by the operation of a motor in cooperation with each other, both ends of a twisted part of a thread mounted on fingers of the levers are repeatedly twisted and untwisted so as to simply pluck downy hairs inserted into the twisted part. Background Art

[2] In general, many downy hairs on the exposed skin, such as the face, spoil the beauty of the skin. Further, downy hairs are covered with dust, and thus the skin gets easily dirty, thereby being insanitary and providing hatred to an opponent, if severe.

[3] A small wart generated on the skin, which is small and longish extra flesh having a nipple shape, is a kind of skin tag. The wart is generated on a portion of the skin, thus spoiling the beauty of the skin.

[4] Accordingly, women having many downy hairs and warts pluck their downy hairs and warts for the purpose of skin beauty and appearance management.

[5] Conventionally, since there is no specific device for removing downy hairs and warts, downy hairs and warts were manually removed. That is, after both tips of a thread are connected by a knot, the thread is folded and the central portion of the thread is twisted. Both ends of the twisted part are respectively held by thumbs and forefingers of both of user s hands. Thereafter, when the thread slowly moves in the longitudinal direction while alternately repeating the spreading out of the thumb and the forefinger of one user s hand and the closing up of the thumb and the forefinger of the other user s hand, both ends of the twisted part of the thread are repeatedly twisted and untwisted, and thus downy hairs are inserted into the twisted part in the proceeding direction and are removed.

[6] In order to pluck downy hairs using the above conventional hair removing method, both ends of the thread are tightly hung on thumbs and forefingers of both of user s hands, and then the thumbs and the forefingers are repeatedly spread out and closed up. Thus, the user feels a pain in his/her thumbs and forefingers. Further, when the thumbs and the forefingers are continuously used, the user feels tired in his/her thumbs and forefingers and thus cannot remove downy hairs. When this hair removing method is used for a long time, joints of the user s fingers are injured, and thus may be bad for the user s health. [7]

Best Mode for Carrying Out the Invention

[31]

[32] Now, a preferred embodiment of the present invention will be described in detail with reference to the annexed drawings. [33] FIG. 1 is a perspective view of a hair removing device in accordance with an embodiment of the present invention, FIG. 2 is an exploded perspective view illustrating the internal structure of the hair removing device of the present invention, FIG. 3 is a perspective view of the hair removing device of the present invention, in which a power transmission unit is assembled, and FIG. 4 is a side view of the hair removing device of the present invention.

[34] As shown in FIGS. 1 to 4, a hair removing device 1 of the present invention includes a base plate 2, a motor 3 fixed to the base plate 2 and provided with a shaft 3a rotated by power supply, a pair of levers 4, both ends of which are repeatedly spread out and closed up in cooperation with each other, when the shaft 3a of the motor 3 is rotated, a power transmission unit 5 receiving the rotary power from the shaft 3a of the motor 3 and causing the both ends of the pair of the levers 4 to be repeatedly spread out and closed up, a support plate 6, to which the pair of the levers 4 is hinged, and a thread 7 installed on the levers 4 for removing downy hairs inserted into a twisted part 7 a when ends of the levers 4 are spread out and the other ends of the levers 4 are closed up repeatedly. The hair removing device 1 further includes a housing 9 provided with a switch 8 for switching on and off the motor 3. Here, the housing 9 is assembled with the base plate 2 such that the motor 3 is accommodated in the housing 9.

[35] The base plate 2, on which various components of the hair removing device 1 of the present invention are mounted, has a thin plate shape.

[36] The motor 3 causes upper ends of the levers 4 to be repeatedly spread out and closed up by means of the shaft 3a, which is rotated by supplied power. The motor 3 is fixed to one surface of the base plate 2, and the shaft 3a of the motor 3 passes through the base plate 2 and transmits the rotary power to the power transmission unit 5.

[37] The motor 3 is switched on and off using the switch 8 of the housing 9, which will be described later, and it is generally known in electric and electronic products and is apparent to those skilled in the art.

[38] The pair of the levers 4 is an essential part of the hair removing device 1 of the present invention, and corresponds to thumbs and forefingers in the conventional hair removing method. Both ends of the levers 4, which are prepared in a pair, are repeatedly spread out and closed up in cooperation with each other by the power transmitted form the motor 3, thus twisting and untwisting the twisted part 7a of the thread 7 installed thereon.

[39] That is, the pair of the levers 4 includes a pair of the bodies having a small thickness, and fingers 4a are respectively protruded from both ends of the bodies so that the thread 7 used to remove downy hairs H can be hung on the fingers 4a. Surfaces of the bodies of the levers 4, which face each other, are inclined or bent in directions going sway from each other so that the levers 4 can be spread out and closed up in cooperation with each other, and thus a space part 4b is formed between the surfaces of the bodies.

[40] Hinge holes 4c are respectively formed through the approximately central portions of the levers 4 so as to be hinged to the support plate 6, and hinge pins 4d are respectively protruded from surfaces of the levers 4 close to the hinge holes 4c so as to receive the power transmitted from the power transmission unit 5.

[41] The fingers 4a are respectively protruded from both ends of the levers 4 in the longitudinal direction. That is, the total number of the fingers 4a is four. A receiving groove 4e is formed in the outer circumferential surface of the tip of each of the fingers 4a in the transversal direction so that the thread 7 is firmly wound on the outer circumferential surfaces of the fingers 4a.

[42] As shown in FIGS. 1 to 3, the hinge holes 4 of the pair of the levers 4 are engaged with assembly pins 6a of the support plate 6. Thereby, both ends of the levers 4 facing each other moves in opposite directions by means of the operation of the motor 3, thus being repeatedly spread out and closed up.

[43] The power transmission unit 5 converts the rotary power, transmitted from the motor 3, into rotary reciprocating motion so that the levers 4 can reciprocate and rotate on the hinge holes 4c.

[44] The power transmission unit 5 includes a rotary plate 51, a first link 52, a second link 53, and a rail 54.

[45] The rotary plate 51 is fixed to the shaft 3 a of the motor 3 a, and is rotated together with the rotation of the shaft 3 a, thus achieving rectilinear reciprocating motion and rotary reciprocating motion of the first link 52 connected thereto. A hole 51a, into which the shaft 3a is inserted, is formed through the center of the rotary plate 51, and a hinge hole 51b, through which the first link 52 is connected to the rotary plate 51, is formed through a designated position of the rotary plate 51.

[46] A pin 52a, which is inserted into the hinge hole 51b of the rotary plate 51 so as to connect the first link 52 to the rotary plate 51, is protruded from one end of the first link 52, and a through hole 52b is formed through the other end of the first link 52. When the rotary plate 51 is rotated, the first link 52 rectilinearly reciprocates and one end of the first link 52 connected to the rotary plate 51 rotatively reciprocates at a designate angle centering on the through hole 52b formed through the other end of the first link 52.

[47] The second link 53 includes a pair of bodies, ends of which are assembled with each other by a hinge pin 53a, which passes through the through hole 52b of the first link 52 and is inserted into a groove 54a of the rail 54, thus performing rectilinear reciprocating motion and rotary reciprocating motion. Hinge holes 53b are respectively formed through the other ends of the bodies of the second link 53, and are assembled with the hinge pins 4d of the corresponding levers 4 by fit. [48] When the first link 52 performs rectilinear reciprocating motion and rotary reciprocating motion, the hinge pin 53a of the second link 53 accommodated in the groove 54a of the rail 54 performs rectilinear reciprocating motion along the rail 54, and the bodies of the second link 53 perform rotary reciprocating motion and are repeatedly spread out and closed up centering on the hinge pins 4d due to the hinge holes 53b assembled with the hinge pins 4d of the levers 4, thus causing the levers 4 connected to the second link 53 to be rotatively reciprocated centering on the hinge holes 4c. Accordingly, the both ends of the pair of the levers 4 are repeatedly spread out and closed up.

[49] The rail 54 is fixed to the base plate 2, and the groove 54a of the rail 54 accommodates the protruding portion of the hinge pin 53a of the second link 53, thus guiding the rectilinear reciprocating motion of the first link 52 when the rotary plate 51 is rotated.

[50] The support plate 6, on which the levers 4 are mounted, is detachably assembled with the base plate 2, and is provided with assembly pins 6a, which are protruded from both sides of the outer surface of the support plate 6 and inserted into the hinge holes 4c of the levers 4. Thus, the levers 4, rotatably assembled with the support plate 6, are rotated on the assembly pins 6a, and are repeatedly spread out and closed up.

[51] The support plate 6 is assembled with the base plate 2 under the condition that the support plate 6 is spaced from the base plate 2 at a designated interval by internal maintenance members 10. The power transmission unit 5 is installed between the base plate 2 and the support plate 6. The internal maintenance members 10 are respectively fixed to the base plate 2 by bolts B.

[52] The thread 7 is wound on the fingers 4a of the levers 4, and serves to pluck downy hairs H and warts from the user s skin. Both tips of the thread 7 are connected, and the twisted part 7a is formed at the central portion of the thread 7.

[53] Both ends of the thread are inserted into the receiving grooves 4e of the fingers 4a formed on both of the corresponding ends of the levers 4. When both ends of the pair of the levers 4 are repeatedly spread out and closed up alternately by operating the motor 3, both ends of the twisted part 7a are repeatedly twisted and untwisted. Thereby, the twisted part 7a plucks downy hairs H inserted thereinto. The thread 7 has the same function as that of a thread used in the conventional hair removing method.

[54] The hair removing device 1 of the present invention, as shown in FIG. 1, further includes the housing 9 provided with the switch 8 for switching on and off the motor 3. Here, the housing 9 is assembled with the base plate 2 such that the motor 3 is accommodated in the housing 9.

[55] Preferably, the housing 9 has the shape of a pistol so as to be conveniently used, and the switch 8 is located at a position corresponding to a user s forefinger when the housing 9 is held by the user s hand.

[56] In the above-described hair removing device 1 of the present invention, when the motor 3 is switched on by pressing the switch 8 under the condition that a user holds the housing 9 by his/her hand, the rotary plate 51, rotated together with the rotation of the shaft 3a of the motor 3, causes the first link 52 to perform rectilinear reciprocating motion, and the second link 53 provided with the hinge pin 53a, inserted into the through hole 2b of the first link 52, moves upwardly and downwardly due to the rectilinear reciprocating motion of the hinge pin 53a along the groove 54a of the rail 54, as shown in FIGS. 5 and 6. Here, since the hinge holes 53b of the second link 53 are assembled with the hinge pins 4d of the levers 4, when the second link 53 moves upwardly and thus the space between both bodies is widened, a pair of the levers 4, assembled with the second link 53, is rotated together.

[57] Thus, ends of the levers 4 are spread out and the other ends of the levers 4 are closed up. Thereafter, when the motor 3 is continuously rotated, both ends of the levers 4 are repeatedly spread out and closed up alternately, as shown in FIGS. 8 and 9.

[58] Accordingly, both ends of the twisted part 7a of the thread 7 mounted on the fingers 4a of the levers 4 are repeatedly twisted and untwisted. When the user slowly moves the hair removing device 1 of the present invention in the longitudinal direction of the thread 7, downy hairs H inserted into the twisted part 7a are plucked, as shown in FIG. 10.

[59]
