Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a slush shoe in which a sole is integrally formed on the lower peripheral edge of a skin body.

[Conventional technology]

Slut shoes are made by injecting a shoe material paste mainly made of vinyl chloride paste into a slush mold (shoe mold) made by electroforming, and then gelling the paste by heating the shoe mold. This product is manufactured by a slush molding method in which a thin film-like molded product formed along the mold surface of a shoe mold is taken out and processed into footwear such as boots or short boots. When this slush molding method is used, it is possible to create natural leather-like grains and wrinkles on the surface of the footwear body, so slush shoes are widely used, especially in high-quality boots.

Furthermore, when footwear is manufactured by the slush molding method, the uneven pattern applied to the bottom surfaces of the sole portion and the heel portion, so-called sole design, is integrally molded.

[The problem that the idea aims to solve]

By the way, in conventional slush shoes, the uneven pattern on the bottom of the heel part is integrally molded, so the heel part wears down due to abrasion between the heel part and the ground due to the use of slush shoes, and as the number of times the slush shoes are used increases. The heel part is worn out and damaged,
The filling made of vinyl chloride resin in the heel part is exposed, and the slush shoes have no choice but to be disposed of, making them a so-called disposable product.

Additionally, since the material of slush shoes is usually vinyl chloride resin, they also have the problem of poor slip resistance.

In addition, the worn bottom surface of the heel part of the shoe sole is filed down to form an adhesive surface, and a lift made of the same material as slush shoes, that is, a lift made of vinyl chloride resin, is applied to this adhesive surface using a vinyl chloride adhesive. There is a method of reinforcing the heel part of the sole of the shoe by bonding it, but in the end, if adhesive is used, the material for the lift is limited to the same material, so the lift, which is made of the same material as slush shoes, has excellent anti-slip properties and It is not possible to improve the wear resistance, and such a method cannot be used at a general repair shop. Furthermore, for the reasons mentioned above, the installation and replacement of the lift is very time-consuming and lacks economy and speed. Furthermore, there is the problem that the lift can become detached from the heel after it has been installed or replaced.

The present invention was developed against the background of such conventional technology, and makes it possible to easily attach a lift to the bottom of the heel of slush shoes without using adhesives, and also allows the use of various materials for the lift. The purpose of the present invention is to provide slush shoes with a lift that allow the user to perform the following functions.

[Means to solve the problem]

The present invention provides a slush shoe in which the sole is integrally molded on the lower peripheral edge of the skin body, in which a fitted part with a concave cross section is provided on the bottom surface of the heel part of the sole, and the fitted part is provided with a one-sided part. To provide a slush shoe with a lift in which a lift having a convex fitting part is fitted.

[Effect]

The slush shoe with a lift of the present invention is provided with a fitting part having a concave cross section on the bottom surface of the heel part of the sole of the slush shoe, and a lift part having a convex fitting part formed on one side of the fitting part. The lift can be easily attached to the bottom of the heel part of the shoe sole without using adhesives, and the material used for the lift is not affected by the bonding conditions, so it can be made from a variety of materials depending on the purpose. In other words, materials with excellent anti-slip properties and abrasion resistance can be used, and the structure described above also makes it easier to prevent the lift from wearing out due to wear between the ground and the contact surface of the lift due to the use of slush shoes with a lift. The lift can be replaced at any time, and the lift can be prevented from peeling off from the bottom surface of the heel portion of the shoe sole.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings, but the present invention is not limited to this embodiment.

In describing this embodiment, a relatively short women's boot will be taken as an example.

1 to 3 show an embodiment of the present invention, and the overall structure of the lift-equipped slush shoe A according to the embodiment of the present invention is as shown in FIG. A shoe sole 11 is integrally molded on the shoe sole 10a, and a fitting portion 12 having a concave cross section is provided on the bottom surface of the heel portion 11a of the shoe sole 11, and a fitting portion 12 having a convex shape on one surface is provided in the fitting portion 12. A lift 20 having a numeral 21 formed thereon is fitted therein.

This skin main body 10 is a main body member of a slush shoe A with a lift molded by a slush molding method, and the material of the skin main body 10 in this embodiment is made of a material that is relatively comfortable to wear and has good walking performance. Although flexible polyvinyl chloride is used, it is not necessarily limited to this, and other thermoplastic synthetic resins can also be used.

Although the hue of the skin main body 10 is light gray in this embodiment, it is not necessarily limited to this and may be any hue.

To manufacture the skin body 10, first, a boot (not shown) is actually made, then a metal layer is formed on the surface of the boot (not shown) by electroforming or metal vapor deposition, and this metal layer is peeled off from the boot. A hollow mold (not shown) is provided.

In this embodiment, the bottom surface of the heel portion 11a of the sole 11 that is integrally molded with the skin body 10 is provided with a fitting portion having a concave cross-section into which the fitting portion 21 formed on one surface of the lift 20 is fitted. Although the hollow mold is provided with a convex projection (not shown) to form the fitting part 12, it is not necessarily limited to this. You may.

Next, a molding material for the skin body 10 (not shown), such as plastisol of vinyl chloride resin paste, is injected into this hollow mold (skin mold) not shown, and then heated from the outside in an oven to form the mold. The sol is gelatinized from the contact area on the inner surface and grown to a predetermined thickness.

Next, the ungelled sol inside is discharged, the remaining gelled layer is heated and cooled, and the fitting part 21 formed on one side of the lift 20 is fitted to the bottom surface of the heel part 11a as shown in FIG. A boot-shaped skin body 10 is formed into which a shoe sole 11 having a fitting part 12 is integrated, and then this skin body 1 is molded.
It is manufactured by spreading a lining cloth (not shown) on the back side of 0.

For example, if the sole 11 has a thick heel portion 11a as in this embodiment, vinyl chloride resin paste may be added to that portion separately.

The lift 20 is formed in almost the same shape as the bottom surface of the heel portion 11a of the sole portion 11, and as shown above, one surface of the lift 20 has a fitting portion 12 with a concave cross section provided on the bottom surface of the heel portion 11a. A convex fitting portion 21 to be fitted is formed.

In addition, in this embodiment, the thickness of the lift 20 is 5 mm.
However, it is not necessarily limited to this, and can be appropriately selected depending on the purpose and use.

Furthermore, in this embodiment, aluminum is used as the material for the fitting part 21, but it is not necessarily limited to this; for example, nylon resin can also be used, but when nylon resin is used, aluminum is used. It becomes more costly.

Furthermore, although urethane resin is used as the material for the lift 20 in this embodiment, it is not necessarily limited to this, and various materials can be used depending on the purpose, such as nylon resin or rubber. In addition, the ground plane 20 of the lift 20

It can be of any shape as long as it can be fitted in.

Furthermore, in this embodiment, a suitable groove 21a is formed on the outer periphery of the fitting part 21 so that the lift 20 will not be accidentally removed from the fitting part 12.

Furthermore, although different materials are used for the lift 20 and the fitting portion 21 in this embodiment, the material is not limited to this, and it is also possible to integrally mold them from, for example, nylon resin.

Furthermore, in this embodiment, the number of fitting parts 21 is 3.
However, the number is not necessarily limited to this, and the number can be appropriately selected as long as the lifts 20 can be reliably fitted to the bottom surface of the heel portion 11a.

Furthermore, when the lift 20 is worn out due to friction between the ground and the contact surface 20a of the lift 20 due to the use of the slush shoes A with a lift, it becomes necessary to replace the lift 20. By making the shape shorter than other shapes, the effort required to remove the lift 20 from the bottom of the heel portion 11a with a screwdriver etc. and the need for a new lift 20 are reduced.
It can also reduce the labor required for installation.

In this way, the slush shoes A with a lift according to the present embodiment are provided with a fitting part 12 having a concave cross section on the bottom surface of the heel part 11a of the sole part 11 of the skin body 10, and the fitting part 12 has a concave shape on one side. Convex fitting part 2
1 is formed by fitting the lift 20, the lift 20 can be easily attached to the bottom surface of the heel portion 11a of the sole 11 without using adhesive. Since the material used is not affected by the bonding conditions, a variety of materials can be used depending on the purpose, including materials with excellent anti-slip properties and abrasion resistance.Furthermore, due to the above structure, the use of slush shoes with a lift A can The lift 20 can be easily replaced even when the lift 20 is worn out due to wear between the ground surface 20a of the lift 20 and the lift 20, and also prevents the lift 20 from peeling off from the bottom surface of the heel part 11a of the sole part 11. It is something that can be done.

Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and even if there is a design change within the scope of the invention, it is included in the present invention.

For example, in this embodiment, relatively short women's boots are taken as an example, but it is not necessarily limited to this. For example, long men's boots, women's boots, and short shoes can be manufactured using the slush molding method. It can be used in any shoe manufactured.
