Abstract

(57) [Summary] [Purpose] In an injection-molded shoe in which the shoe sole is injection-molded on the lower surface of the sulcus, it is possible to easily and reliably prevent resin from entering the sac and to firmly adhere to the sole. [Structure] On the lower surface 1a of the scabbard consisting of the skin 2 and the insole 3,
A sealing member 4 having substantially the same shape as the bottom surface 1a of the scabbard is adhered to seal the entire sewn portion 6 between the scabbard 2 and the insole 3, and nylon, urethane or the like is attached to the bottom surface of the scabbard 1. The resin is injected to mold the bottom part 5 integrally. At this time, the resin on both sides is melted by the injection temperature to obtain strong adhesion.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sole structure of an injection molded shoe.

[0002]

[Prior Art]

 In the conventional injection-molded shoes, the hanging type, in which the hem of the sack and the insole are sewn together, is positioned inside the mold and resin such as nylon or urethane is injected to integrally mold the bottom, is a tape-shaped stitch. A stop member was provided at the boundary between the subcutaneous edge and the insole to prevent resin from entering the inside of the sac.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional technique, there is a problem that wrinkles are likely to occur and it takes time and labor if the bias-like one is used, and the area is small and the adhesive force cannot be expected.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to easily and surely prevent resin from invading a sulcus of an injection-molded shoe. It is to make a strong bond with the bottom.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the technical means of the present invention is an injection-molded shoe in which the bottom is integrally molded by injection molding on the lower surface of the sulcus. That is, a sealing member having the same shape and made of resin on both sides was laid.

[0006]

[Action]

 By the above technical means, a sealing member that is almost the same as the lower surface of the crevice is used to widely seal the lower surface of the crevice without causing wrinkles at the seam between the crepe and the insole, and the resin penetrates into the crevice. In addition, the resin is melted by the injection temperature and strong adhesion is obtained.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In the drawing, A is nylon and urethane on the lower surface of a scabbard 1 formed by sewn a desired skin 2 and insole 3 in a mold B. An injection-molded shoe in which a bottom portion 5 is integrally molded by injecting a resin such as resin is shown, and a sealing member 4 is laid between the skirt portion 1 and the bottom portion 5.

The sealing member 4 is made of a desired material such as cloth or resin and has substantially the same shape as the bottom surface of the crevice 1 and is resin-processed on both sides, and is bonded to the entire lower surface 1 a of the crease 1 with a desired adhesive. By wearing and laying it, the whole area of the sewn portion 6 between the scabbard 2 and the insole 3 is widely stopped.

Therefore, as shown in FIG. 1, when the bottom portion 5 is injection-molded on the lower surface 1 a of the crevice 1, the sealing member 4 prevents resin from entering the crease 1, and The resin on both sides of the sealing member 4 is melted to achieve strong adhesion with the bottom portion 5.

In the illustrated example, the bottom portion 5 has a flat shape, but the shape is not limited to this, and may include spike pins such as soccer spikes and golf shoes. Of course, it is also good. Also, the injection molding method is not limited to the illustrated example.

[0011]

[Effect of the device]

 The present invention is an injection-molded shoe in which the bottom part is integrally molded by injection molding on the lower surface of the hem part, and between the hem part and the bottom part, there is a double-sided resin sealing member having substantially the same shape as the lower part of the hem part. Due to the laid shoe sole structure, the above-mentioned sealing member widens the seam between the scabbard and the insole without causing wrinkles, and prevents resin from entering the scabbard when integrally molding the bottom. It can be easily and surely prevented, and the resin on both sides melts due to the injection temperature, resulting in strong adhesion to the bottom, which is very useful.

FIG. 1 is a vertical cross-sectional front view showing a part of a shoe sole in a molded state.

FIG. 2 is a vertical cross-sectional front view in which a part of the sealing member is omitted and the sealing member is shown separately.

FIG. 3 is an exploded perspective view showing a crepe part and a sealing member.
