Description

Multi-layer shoe with double layer freely changing sole layer

Technical field

The present invention relates to a multi-functional shoe in which a double layer freely replaces a midsole.

Background technique

The shoes we wear are generally composed of a back portion and a lower sole portion connected thereto, the instep portion is fitted to the instep of the wearer, and the sole portion prevents the sole from contacting the road surface. The common sole is divided into an integral overall structure. In recent years, a functional sole that absorbs the impact force generated when walking is also present, which protects the wearer's foot by providing an impact absorbing material in the sole to absorb the impact, and can reduce the foot generated during the long walk. fatigue. Impact absorbing materials are generally cushioned materials, elastomers, and air bags.

Each of the above-mentioned various impact absorbing materials has its own functions, wherein the cushion material is comfortable to use and ensures walking safety; the elastic body has good elasticity, which makes walking easy and pleasant; the airbag has better impact buffering effect. In order to ensure the integrity of the shoe body and prevent the impact absorbing material from falling off, the absorbing material is closed in the sole or integrated with the sole. Therefore, a pair of shoes usually only meet one kind of demand and have a single function. If the wearer has other needs for the comfort, function or appearance of the shoes, it is necessary to purchase other shoes that meet the requirements, which will undoubtedly make people pay more. The cost, and many pairs of shoes are also very inconvenient to keep.

The Chinese invention patent (Patent No.: 200910224744.0) discloses a functional shoe with a replaceable midsole. The sole of the functional shoe includes a replaceable midsole to achieve a multi-purpose effect of the shoe. The sole has only a single layer structure and the shock absorption effect. limited.

In view of this, it is necessary to propose a multifunctional shoe having a double-layered sole.

detailed description

Example 1

1 to 5, a multi-functional shoe having a double-layer freely replaceable midsole as a preferred embodiment of the present invention, comprising a instep 20 portion and a sole portion, the instep 20 portion being affixed to the sole portion The top surface of the sole portion includes a sole and a midsole, the material of the sole being a thermoplastic polyurethane material. The bottom of the sole is provided with a front bow portion 11 and a rear bow portion 12, and the arcuate design can enhance the elastic force of the sole itself and improve the shock absorption effect. The front bow portion 11 defines a first inner fitting groove 111 in the direction of the heel, and the rear bow portion 12 defines a second inner fitting groove 121 facing the heel direction. The first inner fitting groove 111 and the second inner fitting groove 121 A first inner insert 13 and a second inner insert 14 are respectively embedded therein, and the upper and lower halves formed by the first inner insert 13 are respectively corresponding to the upper surface of the inner portion of the first inner recess 111 The opening 15 of the first inner insert 13 is bent toward the heel direction, and the upper and lower halves of the second inner insert 14 are respectively formed correspondingly to the second inner recess. The inner upper surface and the lower surface of the 121 are fitted together, and the opening 15 formed by the second inner insert 14 is bent toward the heel direction. The contact surfaces of these inserts with the inset grooves can be glued together to enhance overall stability. The lower half of the lower surface of the first inscribed groove 111 in contact with the ground is the first lower piece 112, and the lower half of the lower surface of the second inner groove 121 is in contact with the ground. 122. A communication hole 19 is defined in each of the first lower piece 112 and the second lower piece 122. The first lower piece 112 and the second lower piece 122 are provided with a non-slip opening at one end toward the heel direction. The anti-slip port is U-shaped or V-shaped, and the corresponding first lower piece 112 and second lower piece 122 are U-shaped or V-shaped. These anti-slips provide an anti-slip effect. The first inner insert 13 is bent to form a first through hole, and the second inner insert 14 is bent to form a second through hole, and the upper half and the lower half are respectively provided with a second through hole. The bottoms of the first through hole and the second through hole each correspond to the communication hole 19. Preferably, the communication hole 19, the first through hole, and the second through hole are provided as elliptical through holes. By providing freely replaceable inserts in the front bow portion 11 and the rear bow portion 12, the inserts are made of a thermoplastic polyurethane material and cooperate with the inlay grooves to form a two-layer structure, so that the cushioning performance of the overall sole is better. Replacing inserts of other different materials can be a versatile shoe for a variety of environments. The interchangeability of these inserts also makes the multifunctional shoe easier to repair.

The upper surface of the first inner groove 111 and the second inner groove 121 are spaced apart from each other by a plurality of vent holes 18, and the vent holes 18 are through holes, one end of which communicates with the inner side of the instep 20 portion, and the other end is first The inner insert 13 and the second inner insert 14 are in communication.
