Description

A kind of device that is used to protect heel

The present invention relates to a kind ofly at the equipment that is used to protect ground and/or heel, particularly high-heeled shoes, it comprises the flexible hollow body that encloses the card heel.

The footwear that height is followed such as pump or high-heeled shoes are from more and more being liked decades ago, no matter be with footwear or leisure footwear as commerce.When heel is higher than 3cm, be counted as " high following " in principle.By ankle-joint is increased to above the ground, move as same center of gravity based on distribution of weight that changes between the forward foot in a step and the rear foot and formation thus, produce the different body gestures of outstanding chest and buttocks, the danger of the pin of rivering bend of variation, sway from hips and more or less unsafe walking simultaneously and raising.That is to say that the standing surface of heel is more little, injured danger is just big more.Wearing 10 to 14 centimetres high-heeled shoes safety in midway and advancing and need exercise, but on each ground or under for each slope, ground or every kind of surface state, can be dangerous.Even equally under the situation of short root, particularly heel is manufactured to when very thin and therefore has very little standing surface, neither unhurt danger.

The shape of heel can be different, and to the heel in the Pfennig size that is known as spike heel (Stillettos), heel is attenuating on the direction on ground from the wide standing surface under the heel.Conditionally, because standing surface is little, so compressive load per unit area is big, has the danger of sinking to entering the hag face and damaging heel so.In addition, this heel may damage responsive wood ground or timber floor.

GB-PS834,109 illustrate and have described a kind of flexibility " socks ", and it both had been used to protect heel of a shoe, was used to protect ground again.

The objective of the invention is in view of the above; a kind of device that begins the technology of mentioning is proposed; it is that heel provides protection or amplifies cross section for the people who wears footwear with more simple method; thereby the walking on unevenness or sloping floor is become simply, and protect heel or high-heeled shoes not to be subjected to dirt and climatic effect.Simultaneously, can protect responsive ground equally, for example protect timber floor not to be damaged by device of the present invention.In addition, by the device that the present invention proposes, can not have aid and do not have heel to damage jeopardously simple installation and remove again.

For solving this task, the feature of device of the present invention is that basically the end wall of ducted body has the reinforcement or the girth member of sheet, and relative end wall has groove.With simpler method, this device is passed on the heel in front with the end wall of fluting.Reinforcement or girth member that the end wall on the end wall opposite of fluting has sheet are realized the stable standing surface of heel thus and are strengthened ground standing surface simultaneously.The weight of being born by heel no longer acts on ground by the facet of heel, but is distributed on the big plane of the reinforcement of sheet or girth member, reduces on the ground point pressure with this.Especially, because it may become wet or dirty or fracture, under hag face situation, as the soil, sand ground, snowfield and so on, based on not only causing high floor loading injured but also the damage heel by the pin of rivering bend, on little standing surface, the heel footwear sink.By device of the present invention, therefore realize heel is effectively protected.

By being designed to ducted body, realize device with light weight, the confining force that its corresponding requirements is little is reliably to rest on the heel.Also may not need high strength consumption is dismountable this device.The design of the fluting of end wall provides simple possibility, is used for this device is passed heel, and wherein the flexible tongue based on the groove structure can curve inwardly, and can apply the elasticity confining force thus to heel.

Preferably, construct this device, thereby the flexible hollow body is essentially cuboid.Also can consider other shape, wherein have two substantially parallel end walls, it interconnects by the shell that is substantially normal to end face, for example cylindrical or prismatic ducted body.The ducted body that also can consider semicircular in shape is method as an alternative.

Preferably construct this device, promptly the flexible hollow body is by synthetic material, and particularly such as latex, the anti-slip material of neoprene etc. and so on is made.By using anti-slip material, improve the footwear cross-country power that installs device of the present invention additional.For this purpose, can process accordingly with the material on the contact position that the floor contacts, mode is that it is for example extraly by plucking.For pump, perhaps on heel, should have the footwear of very friction value, can make the corresponding smooth or coating of material.

Construct this device in a preferred manner, promptly the reinforcement of sheet or girth member are made by the material such as the durable or dimensionally stable of metal or hard synthetic material.Realize that thus especially, sharp heel does not damage this device and can not clamp-on the flexible material of ducted body as time passes yet.Same weight is dispensed on the end face of ducted body because according to this mode, therefore acts on ground pressure and diminishes.

Sheet reinforcement or girth member can be used as resolution element and are fabricated onto in the ducted body.But preferably construct like this, sheet is strengthened or girth member is cast into end wall, thereby is combined in the hollow body material fully.In manufacture process, strengthen or girth member with the direct combination of form with respect to the corresponding harder sheet of the material of ducted body.

In preferred mode, construct this device system here, thereby the end wall of fluting comprises at least two, preferred four or a plurality of, be configured to flexibility extracting tongue piece by the groove and the material between the groove of end wall center radial outward portion orientation.A plurality of grooves are built in the end wall of fluting, and this device cocoa is abutted against and receives different heel sizes thus, and needn't adjust this device, and wherein flexible tongue applies enough confining forces, with same holding device on the heel of different in width.Therefore omit the independent step that is used for fixing this device and it can fix by simply treading in ducted body with heel.

When the extracting tongue piece of ducted body does not act on the heel one or the same plane, may occur making ducted body to tilt.The reinforcement end face of ducted body no longer is parallel to the standing surface of heel, thereby makes walking become difficult.For stoping this inclination, preferably in ducted body inside, be mounted with the other end wall structure that is basically parallel to fluting, be similarly the supporting wall of fluting, thereby the straight line in crosspoint that connects the groove of end wall and supporting wall passes the reinforcement end wall basically orthogonally.Thereby prevent the inclination of ducted body reliably and improve tack on heel by improving contact area between device and the heel.Especially, under the stiletto heel situation, this structure is very favourable.

Below will further explain according to the embodiment that schematically shows in the accompanying drawings.Wherein, accompanying drawing 1 illustrates the cross-sectional view of the apparatus of the present invention of the line I-I shown in 3 with reference to the accompanying drawings, and accompanying drawing 2 illustrates corresponding to accompanying drawing 1, has the cross-sectional view of heel of embedding and the vertical view that accompanying drawing 3 illustrates apparatus of the present invention.Attached Figure 4 and 5 illustrate has other supporting walls 10 that are placed in ducted body, does not have and have other designs of apparatus of the present invention of the heel of embedding.

Accompanying drawing 1 flag activation is the ducted body of 1 device.It is cube shaped that ducted body is essentially, and has the end wall 2 of bottom and the end wall 3 on top.Shell markers is 4.The end wall 2 of bottom has the reinforcement or the girth member 5 of sheet according to the present invention, strengthen or girth member 5 is cast in the end wall 2.The end wall on top sees to have a plurality of grooves or groove 6 in the vertical view as accompanying drawing 3 particularly, and it constitutes and grasps tongue piece 7.Be the heel 9 that conveniently gets on one's shoes, the end wall 3 on top has opening 8.

With reference to the accompanying drawings in 2 the cross-sectional view as seen, by putting into heel 9, how grasp tongue piece 7, with the cross section of the cross section enlarged openings 9 of corresponding heel 9 in direction bending towards ducted body inside.Elasticity applies confining force on heel 9 towards inner crooked extracting tongue piece 7.

It is wide that cube shaped ducted body preferably has the rib wall long and approximately 2mm of about 25mm, and wherein preferred rubber or latex are chosen as elastomeric material.Hard sheet 5 preferably constitutes the sheet metal with sheet thickness 2mm.

Attached Figure 4 and 5 illustrate the embodiment after the change, wherein for same parts, keep Reference numeral.The supporting wall 10 of same fluting is parallel to end wall 3, and wherein the contact-making surface between heel 9 and the supporting wall 10 improves the contact-making surface that all leans against on the heel, and therefore helps to strengthen confining force.Therefore prevent that heel 9 is in 1 li inclination of ducted body.
