【Example】

 Hereinafter, a slush molded shoe according to an embodiment of the present invention will be described with reference to the drawings, but the present invention is not limited to this embodiment. In describing this embodiment, a boot for a gentleman manufactured by slush molding will be taken as an example. The overall structure of the slush molded shoe 01 of the embodiment according to the present invention is shown in FIGS. In a skin 10 composed of a shoe sole 11 and a cover 12 composed of a front part 12a and a rear part 12b, by making two notches 13 on the upper left and right sides of the front of the cover 12 A sand shelter portion 14 is provided on the instep portion 12a to stand up and a front opening portion 15 is formed. The skin 10 is a shoe body made of a synthetic resin skin molding material manufactured by a general slush molding method.

In order to manufacture the skin 10, first, a master model shoe last (not shown) having an outer shape equal to the outer shape of the skin 10 including the sand shelter portion 14 of the boot as shown in FIG. A metal layer is formed on the surface of the shoe mold by an electroforming method or a metal vapor deposition method, and the metal layer is peeled from the shoe to form a skin (not shown) such as plastisol of vinyl chloride resin paste in a hollow mold (not shown). After injecting the material, it was heated from the outside in an oven to gelate the sol from the contact part of the inner surface of the mold to grow it to a predetermined thickness, and then the ungelled sol inside was discharged and left. The gelled layer is heated and cooled to form a skin 10 in which the sole 11 and the covering 12 are integrated as shown in FIGS. Then, as described above, the tongue-shaped sand shelter portion 14 and the front opening portion 15 are formed by the notch 13.

On the other hand, the mouth opening reinforcement 30 attached to the skin 10 is connected to the back cloth 20 by sewing to the upper edge 12c along the notch 13 on the rear instep portion 12b side and the mouth opening 02, and is folded back to the front side. An annular shape is formed from the partial reinforcing portion 31 and the tightening shield portion 32 in which the tips of the collar portions 32a integrally projecting from the cut corresponding positions 31a on both sides of the partial reinforcing portion 31 are connected by a rubber band 32b which is used as an elastic body. As shown in FIGS. 1 and 2, the tightening shield portion 32 is formed behind the sand shelter portion 14 and shields the front opening portion 15. A back cloth 20 may be stretched and attached to the back surface of the sand shelter portion 14 so as to be stretched and bonded to the back surface of the front instep portion 12a.

The backing cloth 20 may be made of the same material, but different materials may be used around the mouth opening 22 depending on the purpose of use, and different materials may be used for the backing cloth 20 and the collar portion 32a. Good. Materials that can be used are preferably relatively flexible and heat-retaining, and knitted fabrics such as merits and tricots, woven fabrics and non-woven fabrics are preferable, and it is more preferable to combine foams such as polyurethane foam and bores. In addition to these, vinyl chloride resin leather, synthetic leather, natural leather, etc. can be used near the mouth opening 22. In addition, the shoe boot reinforcing material 30 is not limited to vinyl chloride resin leather, but is made of a general material such as waterproof woven cloth, non-woven cloth, or knitted material, as well as a material different from the main body such as synthetic leather or artificial leather. But it is okay. On the other hand, the bonding method is not limited to thread sewing or use of an adhesive. Further, it is considered that a foam material is put in the forefoot reinforcement 30 to absorb the fit and impact of the ankle and improve the wearing comfort.

Next, the operation of the slush molding shoe of the embodiment of the present invention will be described. In the slush molded shoe 01, the shoe opening 02, that is, the shoe opening reinforcing member 30 attached to the upper edge 12c of the rear instep portion 12b of the skin 10, and the elastic band 32b is used for the tightening shield portion 32 which is a part thereof. Because of its elasticity, not only can shoes be attached and removed very quickly and easily, but it also fits closely to the ankles when walking and is comfortable to walk in and comfortable to wear. Further, in the front opening portion 15, since the tightening shield portion 32 integrated with the rear shell portion reinforcing portion 31 is located inside the front shell portion 12a and contracts, the sand shelter portion 14 shields the notch 13. Since they overlap, they are excellent in waterproofness and water repellency and look good. Note that damage to the tip of the notch 13 is also prevented.

Although the embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and the present invention is included even if there are design changes and the like without departing from the scope of the invention. For example, in the examples, the boots for men manufactured by slush molding were taken as an example, but without being limited to this, for example, boots for women, boots, etc. Can be used in molded shoes.

[0014]

[Effect of device]

 Since the present invention has a structure in which the elastic ring-shaped mouth-reinforcing member of the elastic member is attached to the mouth opening having the sand shelter formed by the two cuts as described above, the shoes can be easily and quickly attached and detached. Also, when used, it fits closely to the ankle and is comfortable to wear, and there is no risk of falling off, so safety is high. In addition, since the mouth opening is contracted by the elastic body, the sand shelter part will be covered with a notch, so not only waterproofness and water repellency but also the aesthetic appearance of the design surface will be improved, and the strength against the tip of the notch Since it becomes large and prevents damage, a high quality of the entire molded shoe can be obtained.
