Definitions

• the present invention relates to a shoe last for making a shoe, and a device and a method of manufacturing a shoe using the same.
• the invention also relates to a shoe made by using the above-described last, device and/or method.
• BACKGROUND OF THE INVENTION The shoe last known includes a carcass having a complete foot shape that can be inserted into the upper portion of the shoe to facilitate the use of the sole to make the shoe. However, if solids are involved, the upper portion of the shoe must be forced. A rubber-thick sole will be permanently deformed, so it is recommended to make shoes from an aesthetic point of view and/or functionally.
• a shoe last of the present invention and a device and method of making the shoe are characterized by: a shoe last comprising a body having a complete foot shape and further comprising at least one deformable The inlay is placed in a recess on the underside of the body of the carcass.
• a shoemaking apparatus comprising at least two deformable panels, the pressure surface of the deformable panel surrounding and compressing the last, enabling the manufacture of a shoe having an upper portion, a sole and an insole.
• a shoemaking method comprising the steps of: a shoe last disposed between pressure surfaces of at least two deformable plates, the shoe last being placed in a sole and an upper portion of the manufactured shoe; A deformable plate, the upper portion and the sole compress the shoe last.
• the present invention also provides a shoe made from the above-described shoe plant, device and/or method. Thanks to the deformable inlay, the shoe last allows the sole to be slightly curved so as to avoid permanent deformation when the last compresses the upper part of the shoe. This deformable inlay has good elasticity and has a special pattern. And / hardness, the curvature of the sole can be properly controlled according to its style, size and/or strength of application.
• FIG. 1 is a bottom view of the shoe last of Figure 1;
• Figure 2 is a side view of the shoe last of Figure 2;
• 4 is a bottom view of the shoe last of the embodiment 2; and
• FIGS. 5 to 8 are schematic views of the steps of the shoe last method according to FIG.
• the last of the first embodiment comprises a body of the prior art, such as wood or metal, having the shape of a complete foot.
• at least one deformable inlay is placed in a recess in the sole of the carcass 1, the inlay 2 having elasticity, such as rubber, silicon, ethylene vinyl acetate copolymer EVA (ethylene Vinyl Acetate) Made of polyurethane or other elastic material, the inlay 2 is placed in the middle of the sole of the carcass 1, and the outer surface has an elliptical contour.
• the inlay 2 has a Shore hardness of between 40 and 100 and its inner surface is an upwardly convex curved surface.
• Figure 4 shows that the outer surface of the inlay 2 of the embodiment 2 of the present invention does not have an elliptical contour but is in the shape of a "bean" in which the convex surface faces the outer edge 3 of the sole of the carcass 1 and the concave surface faces the carcass 1
• the cartridge 1 is placed in the upper portion 5 of the shoe, an elastic sole 6 is glued under the upper portion 5 of the shoe, and the insole 7 is placed on the sole 6, thus The lower edge of the upper portion 5 is sandwiched between the sole 6 and the insole 7.
• the second step is shown in Fig. 6.
• the carcass 1 with the upper part 5, the sole 6 and the insole 7, is placed between at least two deformable discs 8, 9 of a pressing device, surrounded by a pressure surface 10.
• Carcass 1. The pressure surface 10 of either of the deformable discs is in contact with the upper portion 5 and the portion of the sole 6, and may be better from the upper portion 5 and the sole 6 The remaining parts are separated in a longitudinal plane.
• the third step is shown in Fig. 7.
• a liquid such as water is introduced under pressure into the deformable plate of the device. Accordingly, the pressure surface 10 can press the upper portion 5 and the sole 6 to squeeze the body 1, due to The deformable inlay 2, the sole 6 and the insole 7 will be slightly bent towards the underside of the carcass.
