The shoe is a shoe provided with a sole formed by the synthetic resin foam body and is characterized in that the touch-ground side of the sole is provided with at least one plate in a zone from the front part of a non-treading part to a toe part comprising a bending part, rigidity and elasticity of the plate are higher than those of the synthetic resin foam body of the sole.
Description
Technical field
The footwear that the present invention relates to are: have the sole that is formed by the synthetic resin foams, or have lightweight footwear by outer bottom and the sole (being called " sole " below) that constitutes by the middle end that the synthetic resin foams form, it has when walking or when running, the sole of bendability and excellent spring and excellent in stability.
Background technology
The sole of the footwear in past adopts the synthetic resin foams, so that the fatigue when alleviating walking improves the resiliency when running.Such as, the occasion of the footwear that formed by the middle end and outer bottom at sole, outer bottom adopts wearability, natural rubber that skid resistance is good, synthetic rubber etc., and the synthetic resin foams of EVA, polyurethane, polyvinyl chloride etc. are adopted at the middle end.
In addition, in order to alleviate the weight of footwear, musculus cutaneus adopts the base material of lightweight, seeks to reduce the density of the synthetic resin foams that sole adopts, or is reduced to necessary minimal state and the reply of use etc. at the thickness of outer bottom.But, though can alleviate the weight of musculus cutaneus, thus obtained effect is little.In addition, the density of the synthetic resin foams by reducing sole part obtains the effect of weight saving, become greatly but have the distortion that the crooked pressure of the walking etc. of sole thus itself causes, and the tendency that also reduces of the elasticity of flexure.If such formation, because sole produces and to be different from the motion of pin, the distortion of shape, or the bounce-back that do not produce appropriateness of the occasion when walking etc., becoming resembles on sand the difficulty the walking and walks, and this mode is not preferred.Be different from the motion of pin, the distortion of shape if sole produces, then constitute when running or the motion of the normal pin during walking hinders.
In addition, in child, old man's etc. footwear, owing to make a little less than the power of bending of pin,, seek the raising of bendability so necessarily require the thickness in the bend of sole, offering groove, reduce sweep.But, for this reason, because sole produces and to be different from the motion of pin or the distortion of shape, or the bounce-back that do not produce appropriateness of the occasion when walking etc., so be easy to generate the situation that difficulty is walked the walking on sand that resembles.
Also have, will be by another step, by punching press etc. and the sole of moulding, forming in the moulding footwear of one by bonding agent etc. and musculus cutaneus, by between sole and musculus cutaneus, insert keeping the core of the middle end that shape uses or the material (shank) of pad heel etc., thus, can seek some improvement of the problems referred to above, but, have the tendency that the bendability aspect reduces.
On the other hand, when sole being formed by injection moulding, in the bonding all-in-one-piece injection moulding of musculus cutaneus footwear, aspect manufacture method, be not easy to adopt to keep the core of the middle end that shape uses or the material of pad heel etc., and if the reduction of density of carrying out the synthetic resin foaming body of the sole injected handle, improve though then have bendability, but, the tendency that the cementability of sole and musculus cutaneus reduces.In order to improve above-mentioned problem at this injection moulding footwear, must keep the cementability of sole and musculus cutaneus, and meanwhile the density of synthetic resin foaming body reduced, and the interpolation by plastic agent etc., the flexibility of synthetic resin also improves.Have because of the reduction of density and the raising of flexibility, sole not only along its length, but also the tendency that broad ways deforms easily.By such formation, the change of shape of the pin of the occasion when following walking etc., the sole also easy deformation that becomes still, is easy to generate the motion that is different from pin, the distortion of shape, and the bounce-back of the appropriateness of necessity reduces terrifically when walking etc.When particularly running, 3～5 times load action of body weight is in sole, or the influence the during flexural deformation of the sole that causes of this load becomes stronger.
So, in order not hinder the desired bendability of sole, prevent the transverse shakiness of toe portion, guarantee walking running stability, people have proposed following sole, wherein, the end in the stacked on top foam of outer bottom,, the toe leading section tilts upward, it is characterized in that the stromatolith at the end in this foam, from the non-portion the place ahead of stepping on to toe portion, and be provided with the groove of a plurality of length directions, and be provided with respectively between the leading section of groove that will these a plurality of length directions and the groove of the width that connects between the rearward end, form embeded slot, at telescopic state, will with the chimeric groove that is fixed in length direction of the corresponding flexible rubber web of this embeded slot in (with reference to patent documentation 1).
But, because this sole has flexible rubber web at bend, so occasion that can be when walking etc. obtains the bounce-back of appropriateness, in addition, the occasion that can prevent when running etc. causes the distortion of following the toe part that the time produces, even in this case, because of the low-densityization that forms sole and curved slot etc., can't prevent that still the bend of sole from producing the situation of following distortion, this is deformed into the different distortion of change of shape of the pin that produces with the motion of following pin.
In addition, in the injection moulding footwear, be not easy such structure of record in the patent documentation 1 is formed, production efficiency reduces.
