Description

shoes with elastic soles

technical field

The utility model relates to a shoe with an elastic sole in footwear in the field of personal and household products, in particular to a shoe with an elastic sole.

Background technique

At present, due to changes in the living environment and lifestyle, people are increasingly comfortable wearing shoes in their lives, especially people are paying more and more attention to leisure sports, and further put forward requirements for shoes with elastic soles to achieve sports and fitness. The comfort of the footwear industry, and the related footwear industry also responds to the needs of the market, and continuously develops shoes with different structures. In recent years, shoes with elastic soles have been continuously developed. The main reason is to use elastic soles to make them elastic. In this way, the problems of the comfort of wearing shoes in people's daily life and the comfort of exercising and fitness can be solved.

Judging from the existing shoes with elastic soles, in many shoes with different elastic structures, the structure has been changed at different levels, and these structures are different according to the mechanism adopted by the designer. The earliest shoe with elastic sole, its structure is mainly that the sole adopts soft foam plastic to form the sole of soft elastic structure to achieve the effect of elastic shock absorption. However, this kind of design mainly adopts the sole method of soft elastic structure, and its main disadvantage is that the elasticity of the sole is limited, which cannot meet the needs of users with high elasticity, especially after a period of use, the soft elastic sole is worn and gradually loses elasticity. , and cause inconvenience to the user, so its practicality is not good.

Subsequently, the shoemaking circle improved a kind of shoes with elastic soles with a completely elastic structure, wherein the more typical ones are the shoes with elastic soles with spring structures sold on the market, as shown in Figure 8, which is the above-mentioned existing A shoe 10 with a spring-structured elastic sole, which includes a shoe outsole 101, an outsole 102, and an upper body 103, and its main improved structure is that a hollow cavity on both sides is provided in the middle of the sole and the heel of the back of the shoe. Parts 107, 108 are located in the cavity parts 107, 108 and are respectively provided with cylindrical springs 104, 105, 106 between the outsole 101 and the outsole 102, and outside the cylindrical springs 104, 105, 106 The surfaces are respectively provided with protective rubber shells 104A, 105A, 106A. Although the effect of this shoe with elastic sole has better elasticity and other enhancement effects than the aforementioned soft sole elastic shoes, it must be able to achieve the effect of elastic sole by setting complex structures such as spring columns. The structure is relatively complicated, the processing procedures are complicated, and the manufacturing and assembly costs are high. In addition, this structural design not only increases the complexity of the structure and costs, but also increases the probability of failure and the difficulty of maintenance. It is not suitable for industrial It is widely used in the world, and there is a need for further research and improvement.

In view of this, related industry has developed a kind of shoe with elastic sole that is provided with elastic plastic block again, and its more typical is the elastic shoe that Edidas produces and sells. Please refer to Fig. 9, which is a structural schematic diagram of a shoe 20 with an elastic sole of soft plastic structure, which includes a shoe outsole 201, an outsole 202, a vamp body 203 and an outsole 207, and its main improved structure is behind the shoe. The root portion is provided with a U-shaped cavity portion 206 that is transparent on both sides. A U-shaped plastic plate 202 is bonded between the cavity portion 206 and the outsole 201 and the outsole 207. An elastic plastic block 203, 204 is respectively bonded between the upper top surface and the lower bottom surface of the shaped plastic plate 202, and the elasticity of the elastic plastic block 203, 204 is used to achieve the effect of an elastic sole. Although this shoe structure with elastic sole has the effect of simple structure than the aforementioned shoes with spring structure type elastic sole, it is found to have the following defects in use:

1. The elasticity of the sole is small: it must rely on the elasticity of the elastic plastic blocks 203, 204 to achieve the effect of the elastic sole. Because this kind of elastic rubber blocks 203, 204 achieve the elastic structure by the elasticity of the soft plastic itself, so for The user's demand for high flexibility is at a loss. This obviously also belongs to a kind of incomplete design, and there is a need for improvement.

2. The structure is relatively complicated and the processing cost is high: because it is bonded with a U-shaped plastic plate 202 between the cavity part 206 and the outsole 201 and the outsole 202, and bonded between the upper top surface and the lower bottom surface There are elastic plastic blocks 203, 204, so the processing procedure is relatively complicated, and the manufacturing and assembly costs are high; in addition, this structure will be unusable and damaged under the pressure and collision of each other for a long time, which also increases the difficulty of bonding and maintenance. There is a need for further improvement.

The aforementioned shoes with elastic soles are all researched and improved for the elastic structure. Although they have different characteristics and can achieve the elastic effect required by the design, they cannot meet the needs of high elasticity, and the general elastic sole design does not No high elastic mechanism is provided, which is obviously a problem caused by the incomplete structural design of existing elastic sole shoes.

In order to solve the problem that shoes with elastic soles need to provide a highly elastic structure, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and generally shoes with elastic soles are not suitable. High elastic structure to meet people's needs, so that the effect of elastic shoes can not be fully and fully brought into play, this is obviously a problem that the relevant industry is eager to solve. This shows that the above-mentioned existing shoes with elastic soles still have many defects, and need to be further improved urgently.

In view of the fact that the above-mentioned existing shoes with elastic soles are not perfect in design, and all have the defect of being unable to provide high elastic structures and effects, the inventor actively researches and innovates based on rich practical experience and professional knowledge. Through continuous research, design, and after repeated trial samples and improvements, the utility model with practical value is finally created.
