CN201839885U - A kind of sole composite structure - Google Patents

Abstract

A composite structure of insole and insole is provided, wherein a polyurethane outsole is provided with a groove to reduce the volume of the polyurethane outsole and further reduce the weight of the polyurethane outsole; the insole and the insole are made of light materials such as ethylene-vinyl acetate copolymer to form a complex and are placed in the groove of the outsole; the total weight of the shoe body is effectively reduced to achieve the design purpose of light weight shoes and provide the most comfortable elastic shock absorption effect for users.

Description

A kind of sole composite construction

Technical field

The utility model particularly provides a kind of sole composite construction relevant for a kind of light weight footwear, not only footwear body gross weight is effectively reduced, and the elasticity shock-absorbing effect of user's the most comfortable more is provided.

Background technology

According to U.S. foot association research statistics, common people are when the normal gait state, and the reaction force that foot bore is about 1.5-2 times of body weight, and the reaction force that bears during running then up to 2-3 doubly.Therefore, both feet are easy to generate fatigue naturally aches, and gets off for a long time and has caused the injury of knee, waist even vertebra virtually.

In order to alleviate the burden of foot when walking or run.The notion of " light weight footwear " becomes the main flow trend of shoemaking industry gradually.

For example, the novel patent of TaiWan, China promptly discloses a kind of light weight footwear for M317186 number, is provided with air cushion in the recess of sole body, makes whole shoes obtain significantly light-weighted improvement.Wherein this air cushion surface is wavy, and hollow is inner irritates when having gas, foot to place on the air cushion, and gas is closed in the air cushion, makes air cushion have elasticity and is evenly distributed in sole.

The utility model content

The applicant is a footwear specialty manufacturer, answers the market needs, develops a kind of sole composite construction that can alleviate foot's burden when walking or running, thereby can generate a kind of novel light weight footwear.

The utility model provides a kind of sole composite construction, and it comprises the end and shoe-pad in the big end of footwear, the footwear.The big end of footwear, be provided with all-in-one-piece groove; The end and shoe-pad constitute complex with light material in the footwear, are positioned in the groove at the big end of footwear.

The utility model will be commonly used the big end and be set as groove, and the volume of timber at the big end of polyurethane is obviously reduced, and directly alleviate the weight at the big end of polyurethane; Described complex is combined into one in the ethylene vinyl acetate copolymer of different blocks with the different hardness transitivity, not only the footwear body weight is effectively reduced, and reaches the purpose of design of " light weight footwear ", and the elasticity shock-absorbing effect of user's the most comfortable more is provided.

The specific embodiment

Below explanation and graphic, be according to the disclosed embodiment of the feature of the utility model, so that the easier quilt of structure technology of the utility model and characteristic range is understood.

Shown in the constitutional diagram of the three-dimensional exploded view of Fig. 1 the utility model and Fig. 2 the utility model.The utility model provides a kind of sole composite construction, and it comprises the end 2 and shoe-pad 3 in the big end 1 of footwear, the footwear.The big end 1 of footwear, made by the polyurethane material of density about 0.6, is set as all-in-one-piece groove 11; With the end 2 in the footwear of the ethylene vinyl acetate copolymer material moulding of density about 0.2 and shoe-pad 3 with one-body molded or paste and combine in the groove 11 that the complex that is constituted promptly is placed in the big end 1 of footwear.This complex is in the ethylene vinyl acetate copolymer moulding of different blocks with the different hardness transitivity; This complex has the different hardness transitivity in different blocks, uses and reduces footwear body gross weight, and the user is provided preferable elasticity shock-absorbing effect.Because ethylene vinyl acetate copolymer has good rerum natura such as flexibility, weatherability, elasticity, chemical proofing and coloring, has been widely used in footwear material at present.Wherein:

The end 2 in the footwear owing to the supporting role that need possess top shoe-pad 3, is to adopt the ethylene vinyl acetate copolymer of the about 65-70 of hardness or the made from mixed materials of ethylene vinyl acetate copolymer and cork;

All frames 31 parts of shoe-pad 3 have provides suitable parcel function to foot, therefore adopts the ethylene vinyl acetate copolymer of the about 50-55 of hardness for fear of distortion;

Directly the insole body 32 that contacts with foot must possess the wear comfort of elasticity for user's the best, is the elasticity ethylene vinyl acetate copolymer that adopts the about 40-45 of hardness;

Insole body 32 is made as shock-absorbing district 33 with respect to the forward foot in a step (forefoot) inner side, by importing vibration absorptive material to reduce the pressure that foot is born, is the shock-absorbing ethylene vinyl acetate copolymer that adopts the about 40-45 of hardness.

Comprehensive the above as can be known, the utility model creates effect significantly they " light weight footwear " with the structure of very simplifying, and has bottom support concurrently and well reach the elasticity shock-absorbing effect.Its practical effect is when unquestionable, and the utility model is never made the city know or see other publication, the real regulation that has met Patent Law.
