Abstract

The utility model particularly discloses a sole structure for a sports shoe. According to the sole structure, a slant groove is formed in the lower surface, corresponding to the heel, of the sole, and enables the sole to be separated to form a heel separating block; extension springs are arranged between a groove rear side wall and a groove front side wall; the extension springs are perpendicular to the transverse extending direction of the slant groove; two ends of the extension springs are fixedly connected through draw hooks in a fixing wall groove and a positioning part of the groove front side wall and the groove rear side wall respectively. The heel separating block is enforced to move backwards and simultaneously stretches the extension springs; the heel separating block generates deformation or displacement of various extents to slow down the downward turnover rate of the heel, and has the anti-vibration function simultaneously; forward elasticity generated by the stretching of the extension springs assists the heel to lift, so that the heel separating block can better conduct the reset and circulation movement and generates forward elasticity on the sole to provide relatively high energy bounce for the sole, so that the sports shoe is easier and more labor-saving in movement and more comfortable.

Description

A kind of footwear sole construction of sport footwear

Technical field

The utility model relates to footwear technical field, especially relates to a kind of footwear sole construction of sport footwear.

Background technology

According to biomechanics Research, most people first land with spring heel outside, and in the moment of contacting to earth, the impulsive force that spring heel is subject to ground reaches the more than three times of its body weight for humans.Therefore, spring heel and lateral heel are the positions that needs emphasis shock-absorbing.At Chinese patent notification number, CN202489292U discloses a kind of anti-vibration structure: the heel region directly contacting with ground at sole is provided with an oblique groove that cuts, it is oblique that to cut groove separated with other positions of sole by the outside of heel region, form heel explant, the pass that is provided with tough stretch-proof between other positions of heel explant and sole is associated.But the heel explant in this anti-vibration structure stressed mobile backward after not one make it the better active force resetting, and the associated effect of playing in above-mentioned patented technology scheme in pass is wherein only to control heel excessively to overturn, prevent from moving after heel explant excessively, the help that does not provide heel explant to reset, also could not provide higher energy bounce-back for sole.

Utility model content

The technological deficiency existing for overcoming prior art, the utility model provides a kind of footwear sole construction of sport footwear, thereby can mask body situation generation distortion and displacement in various degree in base area show preferably shock-proof effect, have higher energy bounce-back and the ability that distortion is resetted, dress motion is more easily laborsaving more comfortable simultaneously.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:

A kind of footwear sole construction of sport footwear, comprise the sole lower surface directly contacting with ground, described sole lower surface is being provided with an oblique groove with rear heel opposite position place, described oblique groove is by the separated heel explant that forms of described sole, described oblique groove comprise the groove rear wall adjacent with described heel explant and with the opposed groove front side wall of described groove rear wall, between described groove rear wall and described groove front side wall, be provided with extension spring, described extension spring is mutually vertical with the laterally extending direction of described oblique groove.The utility model arranges oblique groove and forms heel explant at heel place, at the volley, be subject to heelstrike after the powerful impulsive force in ground, heel explant is forced to backward directions and moves, and in mobile process, stretches and is arranged on the extension spring in oblique groove simultaneously.And heel explant after move past in journey, according to concrete surface state and concrete stressed size, there is distortion or displacement in various degree, make adaptability and move to slow down the heel speed of upset downwards, play the effect of shock-absorbing simultaneously; Extension spring is also stretched because of stressed, and because stretching produces the elastic force of forward direction, after helping on the one hand, heel explant can reset and do action preferably heeloff time, and speed is excessive and deflection is excessive moving backward also to prevent heel explant; On the other hand sole is produced to elastic force forward, for sole provides higher energy bounce-back, while making to wear the utility model sole, motion is more easily more laborsaving more comfortable.

Preferably, described groove rear wall and the vertical fixation wall groove that is inwardly provided with respectively on described groove front side wall, described extension spring two ends are respectively equipped with drag hook, and described extension spring two ends are fixedly connected in described fixation wall groove by drag hook respectively.Preferably, in described fixation wall groove, be fixedly connected with keeper, described keeper vertical sleeve is located at described drag hook.On the front side wall of oblique groove and rear wall, setting up fixation wall groove and keeper separately, has been mainly the effect of location extension spring, makes extension spring can better bring into play at the volley directed elastic force effect and not be offset.Simultaneously fixation wall groove also can prevent that extension spring from, at the volley because of stressed distortion and displacement on occurring longitudinally, protecting extension spring.

Preferably, angle of inclination between described oblique groove and the length direction of described sole is 45 °～60 °, this angle of inclination meets people's foot biomethanics movement characteristic more, divides more exactly the first setdown area of heel, more can play the effect of heel shock-absorbing.

Preferably, longitudinal degree of depth of described oblique groove be described heel explant integral thickness 50%～65%.Can not there is not heel explant from the prerequisite of sole fracture in the design through this longitudinal degree of depth of evidence, assurance heel explant better stress deforms and displacement, thereby shows preferably shock-proof effect.

Preferably, the width of described oblique groove is 5mm～7mm.

Preferably, the vertical range of described extension spring and described sole lower surface is 3mm～5mm.

In the utility model, the described plane bearing of trend paralleling with described sole lower surface that laterally refers to; Described is longitudinally the plane bearing of trend perpendicular with described sole lower surface, also refer to from sole lower surface to one of ordinary skill in the art the vertical direction between known sole upper surface; The length direction of described sole refers to certainly and the pin axis direction of heel opposite position place extremely and between half sole opposite position place.
