Description

A kind of sole

Technical field

This utility model is related to footwear technical field, more particularly to a kind of sole.

Background technology

With the continuous improvement of living standard, people also increasingly improve for the requirement of the footwear worn.Do not require nothing more than It is fashionable, fashionable appearance, and it is also proposed higher requirement to its comfort level.Study through Foot-biomechanics and find, People can be subject to the strong impact power on ground in ground walking or during running, especially with heel elder generation landing instant, ground The impulsive force in face reaches 3～8 times of personal body weight.As walked for a long time or moving, then heel is inevitable Ground can be subject to produce very big impact and vibrations, thus cause not accommodating pain.As do not paid attention to this situation, and leave it Development, then can cause so-called " plantar fasciitis ", and then lead to even more serious consequence.

Utility model content

For the technological deficiency overcoming prior art to exist, a kind of this utility model sole of offer, strengthen the damping effect of sole Really, have prevents heel excessively the anti-of upset from turning over function simultaneously.

This utility model adopt technical solution be：

A kind of sole, including

EVA supporting layer, by sole forepart corresponding with forefoot position and with the corresponding sole of rear heel and mesopodium position Rear portion is integrally formed, and described sole rear portion bottom surface is recessed upwards relative to sole forepart bottom surface, and described sole rear portion bottom surface is provided with Two the first damping grooves；

TPU supporting layer, adaptation sticks in sole rear portion bottom surface and leaves first and described two first damping groove between Damping space；

Buffer layer, in opening towards the U-shaped structure of sole forepart, sticks in the corresponding with rear heel of TPU supporting layer At position, and inside and outside described buffer layer top surface, it is respectively equipped with two the second damping grooves, described second damping groove divides Not with the first damping groove sequence setting, between two leading sections of described buffer layer, it is connected with rubber tension piece；

Skid resistant course, adaptation sticks in buffer layer bottom surface and sole forepart bottom surface.

Preferably, described sole forepart is provided with a cannelure and two oblique slots, and sole forepart is divided by described cannelure Become inside half sole and outside half sole, relative to cannelure, foreign side tilts to be extended two oblique slots backward respectively, and two described oblique Three adjacent regions before and after being divided into outside half sole to groove.

Preferably, described buffer layer is made up of olefin block copolymers.

The buffer layer leading section being preferably located at the inside edge of TPU supporting layer is set to first end, supports positioned at TPU The buffer layer leading section of the outer ledge of layer is set to the second end, and described first end has the inner face towards biped center, Described the second end has the outer face away from biped center；The two ends that described rubber strains piece are connected to described first end The inner face in portion and the outer face of described the second end.

The beneficial effects of the utility model：Due to being provided with the first damping groove in EVA supporting layer bottom surface, in buffer layer top surface It is provided with the second damping groove with the first damping groove sequence, TPU supporting layer is folded between EVA supporting layer and buffer layer, The damping effect at sole rear portion can be greatly enhanced by the first damping groove, the second damping groove and TPU supporting layer, effectively reduce Dispersion ground impulsive force, it is to avoid the injury that may lead to because impact Dipeptiven is strong；Another due to two leading sections of buffer layer it Between be connected with rubber tension piece, by this rubber strain piece buffer layer transversely deforming during stress of contacting to earth can be avoided excessive, protect The service life of shield buffer layer, prevents heel excessively inside and outside upset during contacting to earth simultaneously, realizes resisting and turn over function.

Specific embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings：

As shown in Figure 1-2, the present embodiment provides a kind of sole, including EVA supporting layer 10, TPU supporting layer 20, buffer layer 30 And skid resistant course 40.

In the present embodiment, described EVA supporting layer 10 by sole forepart corresponding with forefoot position and with rear heel and Mesopodium position corresponding sole rear portion is integrally formed, and described sole rear portion bottom surface is recessed upwards relative to sole forepart bottom surface, and institute State sole rear portion bottom surface and be provided with two the first damping grooves 11, each first damping groove 11 is domed respectively.Described sole forepart It is provided with a cannelure 12 and two oblique slots 13, sole forepart is divided into inside half sole and outside half sole by described cannelure 12, Relative to cannelure 12, foreign side tilts to be extended two oblique slots 13 backward respectively, and two described oblique slots 13 are by outside half sole point For three adjacent in front and back regions, the more smoothly nature that moves is made by this cannelure 12 and oblique slot 13, meets human body work Cheng Xue designs.

In the present embodiment, described TPU supporting layer 20 adaptation sticks in sole rear portion bottom surface and subtracts with described two first Leave the first damping space between shake groove 11, under forced compression state, good delaying can be produced by this first damping space Rush damping effect.

In the present embodiment, described buffer layer 30 is in the U-shaped structure towards sole forepart for the opening, sticks in TPU and supports Layer 20 with rear heel opposite position at, and it is recessed to be respectively equipped with two the second dampings inside and outside described buffer layer 30 top surface Groove 31, described second damping groove 31 is arranged with the first damping groove 11 sequence respectively, and described buffer layer 30 is by olefin block Copolymer is made, it is preferred to use INFUSETM 9000 olefin block copolymers of Dow Chemical, and it is with existing polyolefin Elastomer (POE) is compared, and has much unique characteristics：Elasticity and the improvement of heat-resisting quantity balance, have higher knot Brilliant temperature, during processing can rapid shaping, no matter under room temperature or under high temperature, all there is more preferable elastic return and compressive deformation, Wearability is improved.It has more preferably elastic, higher heat-resisting, improvement compared with ethylene-vinyl acetate copolymer (EVA) Compressive deformation, lightweight, stimulus to the sense organ little.
