METHOD FOR MANUFACTURING A SHOE

The present invention relates to a method for manufacturing a shoe, more particularly for assembling the upper and the sole of a shoe.

With reference to Figure 1, this illustrates a conventional method of manufacturing a shoe, comprising an upper 110, a forming device 120 with a plurality of holes 140, and a sole 130. The forming device 120 is used to be sewn onto the upper 110 and to enclose the lower part of the upper 110. The upper 110 and the forming device 120 are placed in a mold, and molten rubber is then poured into the mold to form the sole 130. The holes 140 in the forming device 120 are filled with rubber to help join the upper 110 and the sole 130. However, the bonding force between the upper 110 and the sole 130 is not strong enough.

20 Therefore, there is a need to find a solution to improve the assembly strength between the upper 110 and the sole 130.

An object of the present invention is to provide a—pre-ce-de—pe-u-r—help—to—a-s-s-emfeier—the—ejë—ta

25 soles, including:

an upper, comprising a lateral upper and a lower upper;

a device forming an assembly means, comprising a first plane enclosing said upper

lateral, a second plane connected to said first plane and extending outwards, a third plane connected to said second plane and extending downwards, and a fourth plane connected to said third plane and extending inwards, in which said second plane comprises a plurality of holes; and a sole enclosing said device forming assembly means and said lower upper, in which a material forming said sole fills a space between said fourth plane of said device forming assembly means and said lower upper and said holes in said second plane.

One or part of the advantages and features of the present invention will become readily apparent to a person skilled in the art upon reading the description below, in which a preferred embodiment of the present invention is shown and described, simply by way of illustration of one of the most suitable ways of implementing the invention. As will be understood, the invention can have different embodiments, and its many details are capable of modifications in various obvious aspects, always without departing from the invention. Therefore, the drawings and descriptions will be considered illustrative and

5 In one embodiment, with reference to Figure 2, a shoe comprises an upper 200 including a lateral upper 210 and a lower upper 220, a device forming assembly means 230, and a sole 240. The device 10 forming assembly means 230 comprises four planes. The first plane 231 is used to be sewn onto the lower part of the lateral upper 210 to enclose the upper 200. The second plane 232 is connected to the first plane 231 and extends outwards. There are a plurality of holes 235 in the second plane 232. The third plane 233 is connected to the second plane 232 and extends downwards. The first plane 231 and the third plane 233 are parallel to each other and are connected by the second plane 232. The fourth plane 234 is connected to the third plane 233 and extends inward. The fourth plane comprises a plurality of sawtooth objects and is parallel to the second plane 232. There is a space between the lower vamp 220 and the fourth plane 234. The vamp 200 and the medium forming device

A material, such as rubber, is melted and poured into the mold to form the sole 240. The material fills the holes in the second layer and the space 30 between the lower vamp 220 and the fourth

plan 234 to help assemble the sole 240 and the upper 200.

Referring to Figure 3, which is a cross-sectional diagram of the shoe, the fourth plane, 234, is not in the same plane in cross-section as the other planes. It is shown to aid in understanding the structure. The second plane, 232, is not shown because there is a hole in the cross-section. Figure 4 is the lateral view of the shoe.

Those skilled in the art will understand that the embodiment of the present invention as shown in the drawings and described above is given for illustrative purposes only and is not intended to be limiting.

The above description of the preferred embodiment of the present invention is given by way of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form or illustrative embodiments described. Therefore, the above description should be considered illustrative rather than restrictive. Obviously, many modifications and variations will be apparent to a person skilled in the art. The embodiments are chosen and described in order to best represent the invention and its best practical embodiment, and thus enable a person skilled in the art to understand the invention for different embodiments and with the various modifications that are suitable for the particular use or application

which is envisaged. The scope of the invention is defined by the attached claims and their equivalents, in which all terms are understood in their broadest sense unless otherwise indicated. It will be appreciated that variations may be made to the embodiments described by a person skilled in the art without departing from the scope of the present invention as defined by the claims below. Furthermore, no element or component of this description is intended for public consumption, regardless of whether the element or component is explicitly specified in the claims below.
