DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. A shoe a1 shown in FIGS. 1 to 3 is a soccer shoe embodying the present invention. In this soccer shoe, a leather upper 1 is formed, an insole 2 is placed in a bottom opening of the upper 1, and a bottom side peripheral edge of the upper 1 is formed along the outer periphery of the bottom of the insole 2. The hanging portion 1a formed on the upper part is hung and fixed, and the sealing sheet 4 is attached to the lower surface of the insole 2, and then the synthetic resin shoe sole 3 is formed on the bottom surface of the upper 1 and the insole 2. Is formed by injection molding.

The upper 1 is made by cutting a leather material such as cow or kangaroo according to the shape of each part of the shoe and sewing the skins of these parts together with the lining etc. Configure. Upper 1 sewn as described above
Is formed into a substantially shoe shape by forming a habit in a state where the peripheral edge portion on the sole side is folded inward.

As described above, the peripheral portion of the upper 1 having the bottom folded into the bottom of the shoe 1 constitutes the hanging portion 1a with a predetermined width. The hanging portion 1a is a portion that serves as an adhesive margin when hanging and adhering to the outer peripheral portion of the bottom surface of the insole 2, and is set to have a width necessary to obtain sufficient adhesive strength. In the shoe a1 of this embodiment, the width of the hanging portion 1a is 2c.
m.

A shoe sole-shaped insole 2 is fitted into the bottom opening of the upper 1 constructed as described above, and along the fastening recess 2a formed along the peripheral edge of the bottom of the insole 2. The suspending portion 1a described above is suspended and adhered.

The insole 2 is formed by cutting hard paper or synthetic leather having a thickness of about 3 mm into a shoe sole mold, and a fastening recess 2a having a predetermined width is formed along the outer periphery of the bottom surface. is there. The fastening recess 2a is a recess formed one step lower than the bottom surface of the insole 2. In the case of this embodiment, the insole 2 cut into a shoe sole mold is placed on a flat plate with the bottom surface facing up. It is formed by pressing the outer peripheral surface of the bottom surface of the bottom 2 from the bottom surface side with a mold formed in conformity with the shape of the fastening recess 2a and compressing. In the case of the insole 2, the thickness of the portion corresponding to the fastening recess 2a is compressed by pressing to approximately ½, and the depth of the fastening recess 2a formed by this is the depth of the upper 1 hanging portion 1a. It is configured to be approximately the same as the leather thickness of. Then, when the hanging portion 1a is applied to the fastening concave portion 2a and adhered to the fastening concave portion 2a, the surface of the hanging portion 1a and the bottom surface of the insole 2 are substantially flush with each other. I am doing it.

The width of the fastening recess 2a is set to be approximately the same as or slightly wider than the hanging portion 1a so that the hanging portion 1a of the upper 1 is applied and adhered. In addition, the fastening recess 2a is formed to have a depth substantially equal to the leather thickness of the hanging portion 1a of the upper 1 and when the hanging portion 1a is applied to the fastening recess 2a and adhered thereto, The surface of 1a and the bottom surface of the insole 2 are arranged to be substantially flush with each other.

The above-mentioned suspending work will be specifically described. At the time of manufacture, the upper 1 having the above-mentioned constitutional habit is formed to correspond to the outer shape of the foot as shown in FIG. Fit upside down with respect to the last c.
The insole 2 configured as described above is placed in close contact with the bottom surface of the last c, and the insole 2 is fitted into the bottom opening of the upper 1.

The hanging portion 1a of the upper 1 fitted to the last c as described above is coated with an adhesive to form the insole 2.
The shoe is adhered while hanging along the fastening recess 2a formed on the outer peripheral portion of the side surface of the shoe sole, and is fastened using a nail (not shown) (FIG. 5). As described above, when the suspending of the suspending portion 1a is completed, the insole 2 on the bottom surface of the upper 1 and the suspending portion 1a are substantially flush with each other.

The insole 2 and the hanging portion 1a remain exposed on the bottom surface of the upper 1 outside the sealing sheet 4 (FIG. 6). The exposed portion of the hanging portion 1a is buffed to finely roughen the surface of the material to which the shoe sole 3 is bonded.

Next, as shown in FIGS. 6 and 7, a sealing sheet 4 is adhered to the bottom portion of the insole 1 exposed and the exposed portion 1a of the upper 1 which has been buffed. Sealing sheet 4
Is made of synthetic fiber cloth having a relatively coarse mesh, and is cut into a shoe sole shape having an outer shape slightly smaller than the bottom surface of the upper 1. The sealing sheet 4 is applied with an adhesive to adhere to the bottom surface of the upper 1 in the above state, that is, the exposed portion of the insole 2 and the hanging portion 1a of the upper 1 (FIG. 6). By bonding the sealing sheet 4, the unevenness of the bottom surface of the upper 1 is adjusted, and the joint edge b between the insole 2 and the hanging portion 1a is covered, and the bonding gap generated at the same portion is sealed.

A mold d for injection molding is brought into close contact with and bonded to the bottom surface of the upper 1 after buffing, and a molten resin is injection molded (FIGS. 8 and 9). As a result, the sole 3 made of synthetic resin is integrally formed on the bottom surface of the upper 1. The shoe sole 3 injection-molded as described above is entirely adhered to the bottom surface of the upper 1 by the adhesiveness of the molten synthetic resin.

The shoe a1 has the upper part 1 and the hanging part 1
Although the fastening recess 2a for suspending a is recessed substantially horizontally along the outer periphery of the bottom of the insole 2, the fastening recess formed on the outer periphery of the insole 2 is the shoe a2 shown in FIGS. Like a3, it may be formed in a slightly inclined shape.

In the shoe a2 shown in FIG. 10, the insole 2
The inner peripheral surface of the bottom surface of the insole 2 is inclined by changing the wall thickness at the outer periphery of the bottom surface of the inner periphery of the inner periphery of the inner bottom 2 to form a retaining recess 2a 'along the inclined surface. 'Is designed to tilt somewhat outward. In the shoe a2 configured by inclining the fastening recess 2a ′ as described above, the upper surface of the shoe sole 3 is curved in a concave shape in cross section, so that the fixing property of the bottom surface of the upper 1 to the upper surface of the shoe sole 3 can be improved. it can.

In the shoe a3 shown in FIG. 11, the thickness of the outer peripheral portion of the insole 2 is changed to a tapered cross section in the same manner as described above to incline the outer peripheral portion of the insole 2 and the inclined surface thereof. The fastening recess 2a '' formed in the above is formed into a concave curved surface. The fastening recess may be formed by bending like the shoe a3.

Further, although the shoes a1 to a3 of the above-mentioned embodiment are constructed by injection molding the shoe bottom 3 made of synthetic resin on the bottom surface of the upper 1, the shoe of the present invention is in a flat state. A shoe sole made of rubber or synthetic resin may be bonded to the bottom surface of the leather with an adhesive (not shown). In this case, since there are no steps or depressions on the bottom surface of the instep, there is no need to attach a packing member to the bottom surface of the instep to adjust the step as in the conventional case. In addition, the adhesion area of the shoe sole to the bottom of the instep is maximized, and the gap in the joint surface is eliminated as much as possible to ensure reliable adhesion. The durability can be improved. The shoes targeted by the present invention are not limited to soccer shoes, and may be golf shoes or other shoes.

[0023]

As described above, according to the present invention, the fastening recess is formed along the outer periphery of the bottom surface of the insole, and the shoe sole side peripheral portion of the upper is hung and fixed in the recess. Therefore, the bottom surface of the instep can be made substantially flush with each other when the fastening of the hanging portion is completed. Therefore, when a synthetic resin shoe sole is injection-molded on the bottom surface of the instep, the shoe sole to be molded can be made to have a substantially constant wall thickness. It is possible to prevent the thickness of the product from becoming thin.

When the shoe sole is attached to the bottom of the instep by adhesion, the sole can be entirely adhered to the bottom of the instep, which prevents the sole from peeling off. The durability can be improved.
