Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a top lift for women's shoes that can withstand long-term use.

[Conventional technology]

The heels of women's shoes are thinner than those of men's shoes, and although high heels in particular are extremely thin, they have been made of leather or synthetic resin that lacks sufficient wear resistance and strength.

[Problem that the invention attempts to solve]

The heels of conventional women's shoes are very thin, so if they are made of leather or synthetic resin, which does not have sufficient abrasion resistance and strength, they will suffer from severe wear and may even break, shortening their useful life. There were short and frequent problems that needed repair.

[Means to solve the problem]

In order to solve the above-mentioned problems of the conventional technology, the present invention was developed as a result of finding that it is possible to use metal materials to provide strength and wear resistance, while also using a soft synthetic resin for comfort. It relates to a top lift for use, and includes two or more substantially uniform circumferential walls of a height that are provided on the base and its periphery with slits facing downward and substantially perpendicular to each other, and a wall that extends vertically upward from approximately the center of the base. The lower end surface of the peripheral wall is slightly covered with the lower surface of the synthetic resin, or the lower end surface of the peripheral wall is slightly covered with the lower surface of the synthetic resin, except for the rod-shaped fitting portion. It is characterized in that the lower surface of the resin and the lower end surface of the peripheral wall are embedded in the same plane.

【Example】

Hereinafter, the present invention will be explained in detail with reference to the drawings.
Figure 1 is a perspective view of an example of a metal stud used in the top lift for women's shoes according to the present invention, seen diagonally from below, and Figure 2 is a women's shoe according to the present invention using the metal stud in Figure 1. The third is a perspective view of one embodiment of the top lift for women's shoes seen diagonally from above, and the third is an explanatory view showing the state in which the top lift for women's shoes shown in FIG. 2 is used for high heels. In the drawings, reference numeral 1 indicates a top lift for women's shoes according to the present invention, and metal studs 2 and synthetic resin 3, which will be explained next.
It is made up of. Reference numeral 2 is a metal stud made of aluminum or special steel that has excellent wear resistance and strength and is used in the top lift for women's shoes according to the present invention. It consists of two or more peripheral walls 2b of substantially uniform height, which are provided with a slit 2d in between, and a rod-shaped fitting part 2c, which is provided upright above the approximate center of the base part 2a. base 2
The shape of a can be arbitrarily selected from polygons such as hexagons, quadrangles, and triangles, circles, ellipses, etc., or intermediate shapes thereof. The rod-shaped fitting portion 2c is attached to the heel main portion 4 of women's shoes as shown in FIG.
In order to prevent the top lift 1 for women's shoes according to the present invention from rotating when fixed to the lower part of the base 2a, it is preferable that serrations are provided parallel to the length direction. It is preferable that the upper end part has a truncated conical shape and is processed so that it can be easily fitted into the insertion hole bored at the bottom of the heel main part 4, and 3 is a metal stud 2.
is a synthetic resin with a predetermined shape, which is soft like urethane resin and has relatively excellent wear resistance, and which is embedded except for the rod-shaped fitting part 2c, and the peripheral wall 2b of the metal stud 2 The lower end surface of the synthetic resin 3 is slightly covered, or the lower surface of the synthetic resin 3 and the lower end surface of the peripheral wall 2b of the metal stud 2 are on the same plane.

[Action and effect]

The top lift 1 for women's shoes according to the present invention has a third
As shown in the figure, the heel can be completed by inserting and fitting the rod-shaped fitting portion 2c of the metal stud 2 into the fitting hole at the bottom of the heel main portion 4 of the women's shoe. As soon as the heel of the women's shoes obtained in this manner is started to be worn, the synthetic resin 3 on the lower end surface of the heel wears out, exposing the lower end surface of the peripheral wall 2b of which the height of the metal studs 2 is almost uniform. Due to the hardness of the metal of this peripheral wall 2b, there is very little wear on the heel. Since the exposed portion of the metal stud 2 is only the linear lower end surface of the peripheral wall 2b, and it engages well with the unevenness of the road surface, it is likely to slip like a stud that is in contact with the road surface on a generally widely used flat surface. Nor. Furthermore, since the synthetic resin 3 of the top lift 1 for women's shoes according to the present invention is firmly integrated as a whole with the slits 2d in both the inner and outer parts of the peripheral wall 2b of the metal stud 2, the inner part may fall off or the outer part may fall off. The material does not chip, and the soft synthetic resin 3 makes it comfortable to wear when it hits the road surface when walking, making it possible to achieve the difficult balance of high abrasion resistance and comfort. It has great practical value.
