Abstract

The invention discloses a shoe with a replaceable bottom, which comprises a thin sole (9) integrated with an upper (1), wherein a trapezoidal bulge (8) is integrally formed in the middle of the thin sole (9) from a heel to a toe cap; the trapezoidal bulges (8) are embedded in dovetail grooves formed in the middle of the replaceable sole (10); the replaceable sole is formed by a front part and a rear part or a front part, a middle part and a rear part independently, and can also be in the form of a sole with an integral structure; wherein, the front part and the rear part of the replaceable sole are respectively provided with bolt holes penetrating through the replaceable sole and the trapezoidal bulges of the thin sole in the shoe width direction in a penetrating way, and bolts (2) are arranged in a penetrating way, and one ends of the bolts are fixed by nuts (3). The invention effectively improves the resource utilization rate and avoids the waste caused by the whole being discarded because a certain part of the vamp or the sole is damaged. Meanwhile, the shoe cabinet provides a choice for workers with large working environment change and the like, and can meet the requirements of people on the styles of shoes in daily life.

Description

Shoes with replaceable bottoms

Technical Field

The invention relates to the shoemaking industry.

Background

At present, if the vamp is damaged, the shoes need to be replaced by new shoes in the market. If the sole is damaged, the sole can be manually replaced, which mainly comprises six steps: 1. putting on last 2, heating to remove sole 3, gluing vamp 4, climbing shoes 5, applying glue 6, heating to press shoes. The problem is that the manual replacement of the sole takes a long time and the quality cannot be guaranteed. Meanwhile, the sole is single in form, and the condition of changing styles or freely combining schemes does not exist.

Therefore, a shoe with a replaceable sole is developed, the requirement for replacing the sole is met, and the following problems need to be solved:

1. selection of materials for the connecting portion of the sole and the upper.

2. The design of the fixing structure of the sole and the vamp.

3. How to meet the requirement of smooth assembly and disassembly while ensuring tight connection and seaming of the sole and the upper?

Disclosure of Invention

The invention aims at the problems and provides a shoe with an exchangeable bottom, wherein a sole can be exchanged according to needs.

In order to achieve the above object, the present invention provides a sole-exchangeable shoe, comprising a thin sole integrated with an upper, wherein the thin sole is integrally formed with a trapezoidal protrusion in the middle from a heel to a toe; the trapezoidal bulges are embedded in dovetail grooves formed in the middle of the replaceable sole; the replaceable sole is formed by a front part and a rear part or a front part, a middle part and a rear part independently, and can also be in the form of a sole with an integral structure; the front part and the rear part of the replaceable sole are respectively provided with bolt holes penetrating through the replaceable sole and the trapezoidal bulges of the thin sole in the shoe width direction in a penetrating way, bolts are arranged in the bolt holes in a penetrating way, and one ends of the bolts are fixed by nuts.

In a preferable mode, a shock-absorbing rubber pad is additionally arranged at the bottom of the replaceable sole.

Preferably, the end sides of the bolt and the nut are respectively embedded in the two sides of the replaceable sole in a form of a countersunk hole.

The invention has the beneficial effects that:

1. the resource utilization rate is effectively improved, and the waste caused by the fact that the whole shoe is discarded due to the damage of a certain part of the shoe upper or the shoe sole is avoided.

2. Provides a choice for workers with large working environment change and the like, and brings convenience for work for special occupations. The novel shoe heel is particularly suitable for different living and working environments, such as snowfields, common ground or indoor and the like, and meets different requirements on skid resistance, comfort level, heel height, wear resistance and the like.

3. The shoe can meet the requirements of people on the styles of shoes in daily life, and the pursuit of individuality and newness can be met by combining a plurality of soles with a plurality of vamps in a random manner.

Detailed Description

As shown in fig. 1, 2 and 7, the sole-replaceable shoe of the present invention comprises a thin sole 9 integrated with an upper 1, wherein the thin sole 9 is formed with a trapezoidal protrusion 8 integrally in the middle from heel to toe; the trapezoidal bulges 8 are embedded in dovetail grooves formed in the middle of the replaceable sole 10; the replaceable sole 10 is formed independently of a front portion, a rear portion, a middle portion, and a rear portion, and may be a sole of an integral structure. The front part and the rear part of the replaceable sole 10 are respectively provided with bolt holes penetrating through the replaceable sole 10 and the trapezoidal bulges 8 of the thin sole 9 in the shoe width direction in a penetrating way, bolts 2 are arranged in a penetrating way, and one ends of the bolts 2 are fixed by nuts 3.

Wherein, the shoe is connected by a dovetail groove structure in a mode of sliding from the toe cap and the sole to the inner side. The dovetail groove connecting parts of the middle section of the front part and the middle section of the rear part of the shoe body are connected by bolts, and GB70-76 stainless steel hexagon socket head cap screw bolts are adopted, so that the screw part transversely penetrates through the dovetail groove to achieve the aim of locking the sole. GB/T802.4 hexagonal low-spherical cap-shaped nuts are used at the tail parts of the bolts and are integrally slightly recessed in the shoe body, so that the surface of the shoe body is smooth and is free of protrusions.

Preferably, as shown in fig. 3-6, a shock-absorbing rubber pad 6 is additionally arranged at the bottom of the replaceable sole 10. The lowest layer of the sole is covered with rubber materials which have good wear resistance, skid resistance, elasticity, difficult fracture and better softness, so as to meet the requirements of different road conditions. Moreover, the replaceable shoe sole 10 is composed of a front part and a rear part independently. In the figure, the end sides of the bolt 2 and the nut 3 are respectively embedded in the two sides of the replaceable sole 10 in the form of a countersunk hole.

In addition, the connecting part of the vamp (or the upper) and the sole adopts EVA secondary high-pressure molding with good hardness, elongation, density and elasticity, and is light material PHYLON (MD).

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
