Abstract

PROBLEM TO BE SOLVED: To further enhance the effect of shoe size adjustment and associated foot pain reduction.
SOLUTION: A toe adjustment tool (1) installed near a toe of footwear, the adjustment tool has at least two sponge layers (14, 15) wrapped in a front cloth (13). And The front cloth (13) is preferably a hygroscopic exothermic fiber, and the at least two layers of sponges (14, 15) are preferably made of a low resilience material. As the low resilience material, for example, a low resilience polyurethane sponge can be used.

Description

  The present invention relates to a foot toe adjustment tool. Here, “footwear” can be applied to all, unless the front part and the upper part are opened like slippers.

  Especially for women's shoes such as pumps and high heels, emphasis is placed on design, and it tends to be in a pointed form. Such a shoe is not preferable in terms of comfort because the user's toes do not fit the inner tip of the shoe.

  In order to solve this problem, in Patent Document 1 below, “a substantially triangular shape that is formed of a plastic low-resilience material, has a convex curve so as to enter the tip of the shoe, and has a concave curve along the entire outer edge of the foot tip. And a shoe size adjusting stuffing characterized by having a thickness sufficient to fill the tip of the shoe.

Utility model registration No. 3165534

  The above-mentioned prior art stuffing is said to have the effect of adjusting shoe size and reducing foot pain associated therewith. The present invention aims to further enhance these effects.

  The present invention is a toe adjustment tool installed near the toe of footwear, and the adjustment tool has at least two layers of sponges wrapped in a surface cloth, and the sponge layers are not fixed to each other. Can be slightly opened or slightly displaced from each other (claim 1).

  It is preferable that the front cloth is a hygroscopic exothermic fiber.

  It is preferable that the at least two layers of sponge are made of a low resilience material.

  According to the first and third aspects of the present invention, the layers of at least two layers of sponge can be slightly opened or slightly shifted from each other. For this reason, the tip of the toe not only presses the entire sponge during use, but also enters between the layers, reducing the feeling of pressure and tightness.

  According to claim 2, it is possible to reduce the coldness of the feet in winter.

It is a perspective view in the state where the toe adjustment tool of Example 1 was mounted. It is (a) top view, (b) front view, (c) left side view, (d) bottom view, (e) right side view, and (f) back view of the toe adjustment tool of Example 1. It is a top view which shows a use condition. FIG. 4 is an enlarged sectional view taken along line 4-4 of FIG. (A) shows before use, (b) shows in use.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  The toe adjustment tool 1 of Example 1 shown in FIG.1 and FIG.2 is a stuffing which can adjust shoe size, Comprising: It has the crescent-shaped main body 11 of thickness. Since the main body 11 is curved in a crescent shape, it has a recessed portion 12.

  As shown in FIGS. 1 and 3, the toe adjustment tool 1 is disposed such that the toe hits the curved dent portion 12.

  In this toe adjustment tool 1, 14 and 15 wrapped in a front cloth 13 are divided into two layers and enclosed. Lines 16 shown in FIGS. 2A and 2D are folding folds at the time of sewing the front cloth. The sponge needs to have at least two layers, and may have three or more layers.

  The front cloth 13 may be a normal cloth, but if moisture-absorbing heat-generating fibers are used, the coldness of the feet in winter can be reduced. Examples of the moisture-absorbing heat-generating fibers include fibers obtained by modifying acrylic fibers and rayon fibers. Specifically, UNIQLO "Heat Tech (registered trademark)" Toyobo "EX (registered trademark)", Asahi Kasei "Bemberg (registered trademark)", Mitsuno Corporation "Breath Thermo (registered trademark)" ) ", Etc. can be used.

  The sponges 14 and 15 are preferably made of a low resilience material, and the thickness of each sponge layer is 0.5 mm to 1.5 mm. As the low resilience material, for example, a low resilience polyurethane sponge can be used.

  Although the boundary portion between the two layers of sponge is not fixed, each sponge cannot move greatly due to the frictional force of the sponge surface and the tightening from the outside by the surface cloth. However, the two layers of sponge can be slightly opened or slightly offset from each other. By utilizing this property, as shown in FIG. 4 (b), the tip of the toe not only presses the entire two-layer sponge during use, but also can enter between the two layers, which can be seen with conventional padding. The feeling of tightness and tightness is reduced.
