Description

Shoes that skeleton, shoes overcoat and mortise-tenon joint structural connection replace bonding and sewing up of shoes

Technical Field

The utility model relates to a shoes field especially relates to a shoes skeleton, shoes overcoat and tenon fourth of the twelve earthly branches structural connection replace bonding and sutural shoes.

Background

Shoes are necessities in life, various shoe making technologies are perfect, but most of the shoes are concentrated in the field of composite shoes formed by bonding, so that most of shoes on the market are composite shoes with permanently fixed soles and vamps, a large amount of glue is used for bonding and fixing in the manufacturing process of the shoes, and especially the using area of the bonding glue of the soles and the vamps can directly reduce the air permeability of the shoes; meanwhile, the permanently fixed composite form brings inconvenience for cleaning and incapability of replacing the shoe upper; due to the fact that the manufacturing process of the composite shoe is complex, a certain standard ordering amount is generally needed to evenly distribute the production cost of the single product, and the production mode easily causes inventory pressure.

Shoes are generally composed of a sole and an upper; the sole can be a general term including an outsole and a midsole, mainly has the functions of forming a protective barrier for preventing the sole from being damaged by a road object and simultaneously has the function of buffering the skeletal muscles of a human body; the vamp can be the collective name of all parts above the sole, can include group face, lining, accessory, design thing, port treasure, shoelace etc. the vamp main function is fixed the foot on the sole, also can form one deck protective barrier to foot and external environment simultaneously, for example keeps warm to keep apart cold air, for example keeps apart branch weeds in the woods and plays the effect of preventing the incised wound foot.

The vamp and the sole can be integrally formed shoes, or composite shoes formed by separately processing the vamp and the sole and combining the vamp and the sole together.

When the vamp and the sole are integrally formed, such as EVA slippers, tup sandals and the like, the mode relates to the design and development of the die, and then the die can be used for simple and rapid mass production. The limitation of this method is that the material of the vamp is fixed in the material that the sole can be processed, the material and the shape of the vamp are changed very little, and the function of the vamp is further limited. The disadvantage is single style, because the design is completely limited by the mould modeling; in addition, since the integrally molded shoe is made of a single foam material satisfying the characteristics of the sole, and cannot have elasticity, stretchability and flexibility as those of a textile fabric, there is a problem that the integrally molded shoe cannot be particularly fitted to the foot shape and cannot follow the foot.

When the sole and the upper are two separate parts that are separately manufactured and then combined, the upper edge of the sole wraps the bottom of the upper, and the upper is permanently attached to the sole, mostly by gluing or stitching. In the bonding production process, all parts of the shoe are compounded by high-pollution chemical products such as chemical agents, adhesives and the like, and meanwhile, the processes of heating in an oven, shaping in a cold box and the like are involved; a large amount of forming equipment and chemical agents are needed to be purchased, the power utilization and fire prevention requirements in a forming workshop are high, the fixed investment, labor cost and the like of the forming workshop similarly hinder the expansion of the production scale, and the production cost and the production period of a shoemaking enterprise are greatly increased.

The current solutions to the above problems are mainly:

1. most of the existing composite shoes with non-permanent fixed uppers and soles adopt a linking structure designed between the uppers and the soles, and generally adopt zippers, buckles and the like.

2. In order to meet the requirements of different consumers, the known shoes with integrally formed soles and vamps can only solve the limitations by adding different modeling styles, such as sandals, sailing sports shoes, hole shoes, medical care shoes, chef shoes and the like;

3. the shoe vamp of the other type of shoes is used as a detachable sock structure, most of the shoes are internally sleeved with the shoe body, and the shoe vamp is used as an inner lining of the shoe to play a role in keeping warm.

The disadvantages of the above methods are:

1. the method adopting the link structure is not firm, once one part is damaged, the whole shoe cannot be used, and the operation is inconvenient, for example, the corner of the zipper is not smooth; generally, structures such as zipper/buckle/T-shaped buckle grooves and the like are fixed, the characteristics of breakage and reduction of firmness of upper surfaces exist, and the grooves with specific shapes can form dirt accumulation and are not easy to clean; inconvenient and easy to jam.

2. The shoe with the integrally formed sole and the vamp has no elasticity like a vamp made of textile fabric due to the limitation of materials, so that the shoe only can be designed to enlarge the circumference of the shoe in order to be suitable for the foot width of more people, and most of wearers are too big and not enough to follow the foot, so that the wearers can habitually walk with toe buckles, and the bone deformation is caused by an incorrect force exerting mode for a long time; secondly, the integrated shoe of the toe cap is formed, because of the limitation of the material, when toes touch the toe cap made of plastic, rubber or rubber plastic materials, foreign matters or extrusion feeling can be generated, and the toe cap is not flexible like the toe cap made of textile fabric.

3. The shoes with the detachable sock structures of the inner covers of the shoe bodies can be combined to replace a part of the vamp to a certain degree, but the sock vamps are soft and lack shaping parts, are not easy to fix in the shoe bodies, are easy to shift and are not easy to put on and take off.
