Description

The equipment of footwear is washed in permission in washing machine

Technical field

The present invention relates to for servicing unit technical fields clean and maintenance footwear.Especially, the present invention relates to a kind of equipment that can allow to wash footwear in conventional laundry apparatus.

Background technology

As everyone knows, the footwear of given type can wash.In these types, for example canvas shoes with rubber sole or sport footwear are made by rubber or rubber/fabric conventionally.Also exist the footwear of other types also can wash, the shoes of for example being made by fabric completely or the shoes of being made by rubber completely.Wherein, be commonly referred to as flip-flop sandal, pond footwear etc.

Conventionally, in order to wash footwear, be generally used for or even specific for washing the washing machine of clothes, also applicable to washing footwear.But, may there is many defects and technical problem, because washing machine does not have specialized designs to become washing footwear.Such as, footwear detersive efficiency is poor, produces tearing of abnormal and undesirable wearing and tearing and footwear.

First, even if supposition selects to be suitable for to manufacture the wash temperature of the material of shoes, final result is usually also that shoes can produce uncomfortable permanent deformation, wearing and tearing wrinkle even completely.This wrinkle be due to shoes the inner completely random of drum move freely and produce.Therefore, in normal washing process, shoes clash into each other and clash into drum wall, and in spin cycle process subsequently, shoes remain pressed against on drum wall.Clearly, collision causes the permanent deformation of footwear and large wearing and tearing together with wash temperature.On the other hand, in spin cycle, footwear are subject to strong pressure, and this has increased above-mentioned deformation effect.Irrelevant with the type of footwear, these distortion usually cause the forfeiture of footwear ergonomics feature, shoes cannot be used, because it causes user's pain and uncomfortable disease.

Mainly, with regard to sport footwear (being generally running shoes), well-known, their shape is very important to the achievement of having guaranteed.The people who wears middle-distance race shoes wishes during training session or between match period, running weekly hundreds of km.Obviously, the shoes of distortion may cause the bubble of pain, and even more serious disease is as tendonitis, thereby make it to use for this reason.So unique solution of this problem is to buy new pair of shoes after by washing of drum type washing machine.As selection, shoes must be hand-washed.

Another defect and spin cycle direct correlation.In this stage, shoes remain pressed against on the optional position of drum wall, can not guarantee dry uniformly.In fact, clearly, shoes even each other part are stacked, because water can not be suitably for example, by their different piece (in, the end, upper of a shoe, outer bottom, closing device are as Velcro (Velcro) securing member) outflow, therefore, can not evenly be dried.In fact, well-known, in use, these ends of shoes, are normally impermeable, to prevent that foot from for example intaking in the rainy day.Therefore, when shoes are attached on drum wall, the side of sole is certain to contact drum bottom surface, due to the material of manufacturing sole with and high thickness, sole stops outside water flows to by centrifugal force.In this case, shoes can not evenly be dried, and even after powerful and long rotating circulating, various piece remains wet.

Thereby, it is evident that, it is very inconvenient that above-mentioned defect makes in washing machine, to wash footwear, the most important thing is, and result is really unpredictalbe.

For example in patent or patent application US6067729A, US2003/084585A1 and US5365675A, the known device of attempting to address the aforementioned drawbacks has been described.

US6067729 has described a kind of equipment, and it remains on two shoes on relative position against the drum of washing machine by means of a flexible link, and described flexible link is inserted in shoes, until arrive the interior zone of toe.The diameter of this bar is greater than the diameter of drum, and it presses against toe shoes on the cylindrical wall of drum from inside.But obviously, this bar allows shoes to rotate around its toe in drum rotary course.Thereby, obviously may there is following situations in this equipment: the part of the close heel of upper of a shoe is pressed on equipment, or in drum rotary course, water-filled shoes tend to rotate and pull the part of local upper of a shoe in the position of instep portion around toe, and this situation especially appears in spin cycle, wherein shoes can rotate to the cylindrical wall of sole contact drum always.In the washing stage, the contact point of the toe that these rotations of shoes can also mobile shoes on drum, thus whole shoes-flexible link device is arranged, is geometrically arranged on a non-vertical plane diagonally; Like this, flexible link loses its curvature, last, during pressure drop on toe, and contact lost, and the globality between flexible link-shoe-like devices and the drum of washing machine disappears.

Device in US2003/0084585A1 is provided with the elongated tubular with T shape end, and described T shape end is suitable for being assemblied in two shoes, and two shoes are forced into sole and in opposite location, contact the cylinder side wall of drum.T shape end can not hinder wet upper of a shoe towards the motion of sole; In wash cycle process, the sustained stress of fabric/upper of a shoe and crooked dangerous to the seam of upper of a shoe, hot melt portion or the generation of gummed seam, and shoes do not design for this reason.In addition, vertical position in rotary course, within the underlaid shoes of weight of whole equipment and shoes above, in addition, the effect that the T shape of equipment partly produces is only implemented in the finite part at the end partly within shoes and in footwear, under the effect of higher pressure, cause thus the latter's permanent deformation, this distortion makes footwear dress uncomfortable.

In US5365675A, shoes are shelved on from footpath and upwards insert on the outstanding pin of extensible bar drum, and tie up here by the shoestring system around them outside.Due to shoes only below sole by partial restriction, and major limitation is on the outer surface of upper of a shoe, with and be to be more precisely only fixed on heel region, in the less forward part that is effectively fixed on sole and upper of a shoe, so in washing and rinse cycle,, in drum rotary course, itself is absorbed in inside shoes, at sole, subject to continuous flexing, described flexing may cause the disengaging of on-fixed insole; In addition, due to the cause of shoestring and pin, the upper of a shoe of instep forward part subjects to continuous wearing and tearing, or at least subjects to cyclic stress, and shoes do not design for this reason.

In above-mentioned all three kinds of situations, shoes are taked such position, that is: during drum rotation, especially during effectively washing required revolving process, near the peripheral part (conventionally also impermeable) of sole that is positioned at of impermeable sole and upper of a shoe stops water to flow out from shoes, thereby causes possible sewage to be detained, until washed, dirt also may remain in shoes inside, thereby causes unsatisfactory or bad washing.In fact, in these examples, sole mostly faces the cylinder side wall of drum, and the inner concave of shoes (areas of footwear of holding pin) is in the face of the rotation of drum itself.In US2003/084585A1, this position is constant, in US6067729A and US5365675A, during revolving process, is especially such.Centrifugal force moves radially water, so sole tends to stop water to flow out from shoes are inner.Because the hydropexis causing is thus between upper of a shoe and sole, shoes need long time dry, seam, thermal welding portion and gluing edge cause issuable high pressure and dying down in retention areas.

In addition, in all above-mentioned three kinds of situations, equipment is realized partly in two opposed area that are more or less restricted of the cylinder side wall of drum, due to equipment be by pressure fixing on the cylindrical wall of drum, this may cause drum distortion, and drum does not have to design for these concentrated effects sometimes.

Summary of the invention

So target of the present invention is to provide the equipment that footwear are washed in a kind of permission in washing machine, it has overcome whole above-mentioned defects.

Especially, according to the first group of embodiment that is common to three possible distortion of the present invention (for this reason, referring to for example Fig. 1, Fig. 6 and Fig. 8), be provided with at least one support component 5,205,305, it comprises that fixture 3,203,303 is to join support component in use on the profile of drum.Like this, when drum rotates, said elements can stably be rotated.In use, device 7,17 cooperates together with described support component, at least one shoes are hanging on described support component 5,205,305, so as can washing, rinsing and/or rotation shoes, shoes are remained essentially in to the position (especially referring to Figure 11) corresponding to the associated support of its hanging position simultaneously.

Enter structure detail of the present invention, Fig. 1 and Fig. 2 have specifically shown the first preferred embodiment that the present invention is feasible.According to this structure, three support components 5 are realized with the form of plate, and are substantially V-arrangement, so that three corresponding classical calendering parts 6 of reproduction washing machine drum.Application calendared sheet in drum inside is guaranteed better grasping, and guarantees that thus drum drags above-mentioned support component better.

According to this first preferred embodiment of the present invention, in order to the fixture 3 in use support component 5 being bonded on the profile of drum, comprise framework 3.In CONSTRUCTED SPECIFICATION, this framework consists of three brackets 4, and described bracket has the interior profile being suitable for around corresponding three support components 5, therefore also V-shaped substantially.Especially, bracket is connected on support component 5 firmly, realizes thus the cramped construction of a single-piece.As described in Fig. 1 and 2, three bars 8 interconnect bracket respectively, thereby give on the whole equipment 1 triangle substantially.Each bar 8(for this reason, referring to Fig. 3, Fig. 4 and Fig. 5) by correspondingly hinged two parts 9 and 10, formed, to can relative to each other move, especially collapsible.As what highlight in Fig. 3, by use sleeve or the analog can sliding in the described part 9 and 10 of bar 8, by described part relative to each other on rigidity maintenance straight line.Especially, for describe simple for the purpose of, with reference to a part for outstanding one of them bar 8 of describing only in Fig. 4, end 10 provide one with the rigidly connected thread ring 12 in this end, sleeve can be screwed on described thread ring.Like this, sleeve can from the first state (at this first state sleeve, from the described collar, unscrew, and be free to slide in described part 9, enter as shown in Figure 5) another state (at this state, sleeve is tightened on the collar, closed articulated elements, as shown in Figure 3).Like this, under state as shown in Figure 5, because articulated elements can be freely movable, the framework that can collapse, reduces the overall diameter of whole triangular devices, thereby and allows this equipment easily insert the drum of washing machine and remove from the drum of washing machine.On the contrary, bar is fixed on support component on the wall of drum 2 firmly in expanded position.

The of the present invention second preferential embodiment (referring to Fig. 6 and Fig. 7) provides a star framework 203.In this case, one center joint 213 is coupled a plurality of bars 208 according to star arrangement, wherein, described bar radially extends towards drum wall, like this, the support component 205 that is connected in bracket 204 can be firmly grasped the inner side of the calendering part 6 of drum, as first structure institute accurate description.

As what highlight in Fig. 6, two in three bars 208 is single-piece, and the 3rd bar is extension type.The 3rd bar thereby can comprise a simple releasing device 211, a button for example, described releasing device allows relative to each other to discharge/block two parts 209 and 210.So described part 210 can realize slides the cylindrical shape bearing of described part 209 is inner, like this this part 210 within it portion move backward, or extend towards outside.Enter the structure detail of this releasing device, this releasing device comprises that one is arranged in the resilient key in described part 210.This pin is (for the purpose of describing simply, this pin is not shown) from a position of the cylindrical surface of described part 210, stretch out, and, due to the elastic reaction that for example a spring applies, during sliding, this pin remains adhered in the inner cylindrical surface of this part 209.Described part 209 is provided with corresponding hole in addition, like this, takes out default height, the pin of described part 210 hole of exposing that just contact forms in described part 209 once realize for carrying out under elastic reaction.Thus, with respect to described part 209, block described part 210.Then, only by use, point and compress pin, just can make this pin retraction hole inner, and make in described part 210 retraction parts 209.

As shown in Figures 6 and 7, center joint 213 can be rotatably connected on bar 208.For this reason, Fig. 7 has highlighted being articulated and connected of Gan208Yu center joint 213 better, therefore, when using end, can also be with the mode closure bar of fan.From the angle of volume, this solution is favourable.Like this, can be with simply, mode discharges described support component 205 from the calendared sheet of washing machine fast, with globality from drum, remove whole equipment, or whole equipment is inserted and is connected on drum.

When taking out, need bar 208 solderless wrapped connection head rotations.Preferably, for the consideration to functions of the equipments stability, also can between bar 208 and bracket 204, arrange at least one rigid connector.The above-mentioned connector providing can be preferably rigidity with respect to telescopic rod, and remaining connection can be also rotary-type.

Obviously, with reference to above-mentioned structure, can easily realize the solution with two, three or more bars.In addition, the more bars 8,208 that even surpass single bar can be embodied as the opened/closed system of extension type, radial type or their composite type, but do not depart from protection scope of the present invention.

The 3rd preferred embodiment of the present invention (for this reason, referring to Fig. 8) can be transformed to one or more support component 305 is provided, but have band to be useful on, does not adhere to the framework that is positioned to the support function on drum.In this case, as selection, fixture can consist of the magnet 303 being arranged on support component, and described magnet has directly been realized the adhere to connection of support component to drum.For clarity, Fig. 8 has shown according to the cross section of the support component 305 of this structure, has shown simply magnet 303.In addition, from described figure, it is apparent that, this support component is V-arrangement, is equal to above-mentioned respective support elements 5 and 205 completely.Except magnet, also can use simple screw device etc., it allows simple detachable and is connected on drum.So, in this case, can be the screw that support component is provided for quick coupling.

In addition; in all above-mentioned preferred embodiments; the covering of flexible material can also be provided on support component; this shroud arrangements in use can the surface in the face of the calendering part of drum on; so that the unlikely scuffing in surface of protection drum; and form can abatement apparatus with roll contacting of any gap between part, like this, in drum rotary course, there is not any contact that has noise.

In addition, from foregoing description, it is apparent that, in fact, in the structure of all descriptions, the application of the support component corresponding with the calendering part of drum all has guarantees to firmly grasp better the function being also rotated better thus.But, also it is apparent that, this tendency neither be necessary, also can in the smooth part of drum, provide the connection to equipment.

Continue to describe structure of the present invention, Figure 11 has described at least one shoes has been hanging to reference to the first above to the device 7,17 on the described support component 5,205,305 of the third structure.As what clearly illustrate in the accompanying drawings, shoes hang on drum, that is to say, it is suspended in drum, do not contact with drum.

Enter structure detail, these devices comprise the bearing 17 that at least one forms corresponding to support component in combination, and this bearing is in use in order to releasably to lay the suspension unit 7 of shoes.For clarity, the bearing 17 showing in institute's drawings attached is all relevant with various preferable configuration of the present invention.

As described in below inciting somebody to action better, this suspension unit 7 provides the part that is inserted into shoes inside, and shoes to be washed must be clothed in this part.This part is with the surperficial 19A that contacts or face the insole of shoes.In a preferred embodiment, this part is shoe tree, or is equivalent to copy the shape part of people's pin or shoes profile, and integral body marks by numeral 19.Suspension unit 7 touch or in the face of the above-mentioned surperficial 19A of the insole of shoes, to be actually a part or its shape of shoe tree corresponding with the vola of people's pin.In a preferred embodiment, this surface 19A of suspension unit 7 is towards the rotation of drum.

Obviously, in other embodiment of suspension unit, this surface can be not corresponding with the vola of people's pin.For example, suspension unit 7 can provide the part that is inserted into shoes inside, described part is only formed by toe and heel, described toe is connected to adapt to the bar of the size of shoes by length is adjustable with heel (for example, by screw/nut system, or by being compressed to the elastic rod of minimum dimension from full-size, be similar to for helping shoes to keep the shoe tree of their shape when not using); In this case, the surface in the face of the sole of shoes and the rotation of drum of suspension unit can be a part for the bar between toe and heel.

In a preferred embodiment, suspension unit 7 comprises the engagement pin 18 that is connected in shoe tree 19 and the device 20,21 that allows described shoes to be fixed on shoe tree.These devices 20,21 can comprise the band 20 that is connected in shoe tree, and described band is provided with Velcro type hasp (closure) 21 in end.As selection, described hasp also can be formed by button/buttonhole system, snap-fastener etc.According to all preferable configuration of the present invention, each support component 5,205,305 preferably provides two bearings 17.

The 4th preferable configuration of the present invention (for this reason, referring to Fig. 9 and 10) provides above-mentioned device 401, and it comprises the suspension unit 407 for footwear substantially, and this suspension unit is substantially identical with above-mentioned suspension unit 7.Unique substantive difference (referring to Fig. 9 and 10) is that this suspension unit comprises bayonet joint 418 or an analog, in the suitable bearing 417 on its drum that is arranged to insert direct formation or be arranged in advance washing machine.In this meaning, say, drum is in calendering part or can provide in other regions the simple male part that is designed to receive joint 418.Therefore, drum has been arranged to connect this suspension unit 407 in advance.

As selecting (specifically referring to Fig. 9 and 10), in order to strengthen this connection, drum can comprise support component 405 or directly be formed by the support component being arranged in advance from the outside within calendering part 6.The connection of support component 405 can be by for example plain screw or by realizing from outside by the same drum sheet material encapsulation calendering part that limits its drum.Related to this, as shown in figure 10, triangle is especially convenient, and it is suitable for adapting to the shape of calendering exterior support partly.According to this solution, bearing 417 forms in joint 405, to engage in use suspension unit 407.

For all described structures of suspension unit 7,407, should be noted that shoe tree 19 manufactured by plastic material or light metal alloy, or manufactured by any substantially non-absorbent material, and it is provided with a plurality of through hole 19B.Specifically, an especially favourable embodiment comprises that the manufacture of shoe tree makes its inner hollow (with the cavity of dashed lines labeled, being labeled as 19C in Figure 11) and has enough thickness.Like this, water flows in cavity by hole, and discharges at a high speed.So shoe tree, except guaranteeing that liquid is best and flowing out, also has the additional function of efficient rinsing, thus the hydropexis of avoiding the existence due to shoe tree to cause.

In addition, owing to there being a plurality of minor diameter through holes, the water rate of outflow is obviously greater than the speed of the water being produced by rotation, and this makes clean result better.

From accompanying drawing, easily see, should again point out, the position that shoes are dressed shoe tree 19 is thereon arranged so that " sole " of shoe tree is towards the axis of drum, causes the sole of shoes directed in the same manner.Like this, in the rotary course of rotating circulating, do not have to hinder the water moving radially towards the cylindrical side surface of drum to flow out or flow out near the impermeable periphery of the upper of a shoe it from the impermeable sole of shoes.

In general, term " face " with " is towards " the relevant axis in the surface with suspension unit 7 of drum, the surface that refers to body is mainly positioned in a plane but not through the axis of drum.From geometric view point, in fact can say, the surface of the axis towards drum of this suspension unit is divided into two parts by drum, the rotation that wherein first part comprises drum, and the part of the relevant upper of a shoe that the second part is suitable for comprising shoes (being sole outside);

From aspect, most critical ground, describe structure of the present invention above, below will describe its operation.

Figure 12 and Figure 13 have shown respectively the first and second preferable configuration of the drum inside that is arranged in use washing machine.Obviously, the 3rd structure and the 4th structure have the function of all fours, do not show for the purpose of being only used to simply.First, equipment is inserted into the inside of drum, to be fixed on drum wall or by magnet or the analog described in the 3rd structure and be fixed on drum wall by framework (referring to the first and second structures).As described in two stages of Figure 11, then by shoes through on shoe tree 19, and be fixed on shoe tree 19 by band 20 or by shoestring.Now, by engagement pin 18 is combined in bearing 17, shoes are hanging on corresponding bearing 17.

With regard to the 4th preferred embodiment, bayonet joint 418 is inserted in the bearing that drum (or bucket in) arranges already in advance.According to the requested number of shoes, repeat this operation, until realize example situation as shown in Figures 12 and 13, six shoes of this device support (three above, and three are in the back---referring to the bearing 17 in Fig. 1) wherein.As what clearly give prominence in Fig. 2, in fact this equipment can lay three pairs of shoes of as many as.At this, can wash shoes, these shoes are subject to the restriction of equipment, are prevented from moving with any at drum internal impact, but are fixed on the position that it hangs always.

When washing finishes, by engagement pin 18 effects, the whole suspension unit 7 of the shoes with hanging is removed from drum, or the in the situation that of suspension unit 407, with respect to device 401, remove bayonet joint 418.Finally, the in the situation that of first, second structure, the removing device by the bar 8,208 of the framework that collapses, or the in the situation that of the 3rd structure, the removing device by directly removing element 305.

It should be pointed out that in spin cycle, the centrifugal force that acts on shoes will make shoes keep motionless, and shoes are forced on the shoe tree that its insole is in sole inside.Like this, conventionally between the lower sole of shoes inside and insole, extend the fabric of upper of a shoe of certain centimetre by the outsole high compression by shoes, the compression of insole on shoe tree can effectively keep fabric, and the effect of stress that does not make the thermal welding portion of upper of a shoe on sole or glue joint or suturing part be subject to being produced by centrifugal force, described centrifugal force can produce unidirectional tractive force at gummed region or the zone similarity of fabric, and described tractive force can cause the fabric of upper of a shoe to depart from from sole.

In spin cycle, the water that shoes flood is subject to centrifugal action, and flows out towards shoes are outside in the region of pin entrance, or a part for the upper of a shoe by porous flows out, or the inner surface of its upper of a shoe of stretching or outer surface.Like this, concerning every shoes, turning effort is all uniformly, and is very effective; In fact, the sole of general motion footwear or technology footwear (they are fixed on equipment) is normally impermeable, it is with together with the inner fovea part of cylinder side wall towards drum, in turning effort process, by means of equipment of the present invention, water can flow by the described wall from shoes towards drum, can not hindered by impermeable sole.

In revolving process process, the sole of shoes, by being mainly subject to and sole being produced the effect of the various uniform pressures of same type therebetween in walking, that is to say, is subject to the shoes clearly effect of the stress of design for this reason.

Like this, by means of equipment of the present invention, can not occur in incidental following problem while not using this equipment: the shoes that wash are inner mobile arbitrarily at bucket; The sole below that has produced shoes is placed to the possibility contacting with the cylindrical wall of drum.By means of equipment of the present invention, prevented: water flows towards impermeable sole under the effect of centrifugal force; Depart from shoes and remain on insole or always remain on roughly the inner frame interior volume of the sole that the protrusion space by the hole with towards insole forms, thus the scope that hinders rotary manipulation.Utilize equipment of the present invention, when washing finishes, shoes, by have extremely low residual humidity in fabric, the most important thing is, in shoes, the distribution of humidity will be uniformly, can realize so subsequently uniformly and be dried, and can not cause the distortion of shoes.

Should be noted that in the situation that loading washings and pre-wash water, can in drum inside, realize given height, the rotation replacing will start, and a series of clockwise directions rotate and the rotation of a series of counter clockwise direction.When shoes are during in lower partial rotation, the cause of the mode moving due to them, they are intake in very effective mode.It is inner that water flows into shoes by the shoe tree that is installed with hole by suspension unit 7 19, and during movement, water will flow in the inner cavity 19C limiting of shoe tree 19, and flows out from other holes 19B, thereby produces numerous washing jets at the inwall of shoes simultaneously.During rotation, when shoes rise to the inner higher height of bucket, water flows into the interior zone of the shoes that also there is no arrival simultaneously; Like this, the water flowing out by hole 19B from shoe tree inside will produce the jet of flow velocity increase.

On the one hand, the shoe tree 19 that is installed with hole allows the inflow of water into all interior zones of shoes, thereby improve detersive efficiency under the effect of the more speed of the water flowing out from jet, on the other hand, it keeps the shape of shoes during washing, prevent that it from being pressed or being out of shape, even in the situation that the wash cycle of utilizing hot water is provided.

To impinging upon the current known equipment of describing in referenced patents, it is evident that very much, according to equipment of the present invention, can more stably block the shoes that will wash, thereby avoided collision or the wearing and tearing of shoes and avoided distortion, in addition, also avoid hydropexis the region relevant with sole of shoes inside and near neighboring area.Finally, the present invention allows to realize certain more effective clean result, when each rinse cycle finishes, after revolving process, due to without delay effect, the water electrode of staying in shoes is few, therefore, each clear water loading contributes to effectively to wash when last rotating circulating finishes.

At this, it is evident that very much object of the present invention all realizes.Especially it is evident that very much, such equipment make the washing of shoes avoided their collisions each other and with the collision of drum wall, thereby avoided the damage to drum, to the distortion of shoes and wearing and tearing.In addition, due in spin cycle, shoes can not be placed to the cylinder side wall that makes sole face drum, so being dried of carrying out is very efficient.

Above-mentioned specific embodiment can show the present invention from conceptual viewpoints, so other people, utilize known technology, do not need further research and in the situation that not departing from design of the present invention, just can in various application, change and/or revise this specific embodiment, therefore, such modification and change all should be considered to being equal to of specific embodiment.The device and the material that embody various described functions can have various characteristics, but all do not depart from protection scope of the present invention.It should be understood that used expression and term are only descriptive, not as restricted object.
