Abstract

(57) [Summary] [Purpose] An insole for footwear should be made inexpensive, as well as stabilizing the soles of the foot that come into contact with the footwear and making the foot less tiring. [Constitution] On the insole, the convex portion of the bow-shaped front non-slip portion 3 is made to correspond to the base of the toes on the sole of the foot which is contacted when the footwear is worn, and the elliptical middle slip is made to correspond to the arch portion. Stop 4
The convex portions of are formed respectively. The middle non-slip part 4 is bulged so that it gradually becomes higher from the periphery toward the center. A shallow recess is formed between the front anti-slip part 3 and the middle anti-slip part 4, and a large number of small protrusions are erected above the bottom surface to form the ventilation part 6. A sloped portion 2 that gradually lowers inward is provided in the peripheral portion of the upper surface of the insole.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of footwear, particularly insoles such as sandals and slippers.

[0002]

[Prior art]

 Conventionally, for example, as shown in FIG. 9 and FIG. 10, a sandal insole has a so-called fiber U formed on one side of a so-called fiber U, which is formed by stiffening gelatinized fibers and superposing them. In many cases, W is attached, and then a sheet material V made of flexible vinyl chloride or the like is further covered, and the peripheral edge of the sheet material V is adhered to the peripheral edge of the back surface of the fiber U. This is attached or sewn onto the bottom body 1 as in the case of the embodiment of the present invention in FIG.

[0003]

[Problems to be solved by the device]

 The conventional insole is flat and is composed of three layers of a sheet material V, a sponge-like rubber W, and a fiber U in order from top to bottom. For this reason, manufacturing is time-consuming and costly. In addition, when wearing sandals using such an insole, the back of the foot feels hard and the sole of the foot is slippery and easily tired, despite the fact that the insole contains the sponge-like rubber W. there were.

The present invention provides an insole that improves the above-mentioned drawbacks of the prior art, can be manufactured at low cost, and makes the sole of the foot stable and comfortable when wearing shoes. To aim.

[0005]

[Means for Solving the Problems]

 The insole according to the present invention is made of elastic polyurethane foam integrally molded into a thick plate.

Further, the insole may be formed with a convex portion and a concave portion so as to correspond to the irregularities of the sole of the foot that come into contact with when the shoe is worn.

[0007]

[Action]

 The insole is easy to manufacture because it comes out only by integrally molding elastic polyurethane foam. Also, when wearing sandals with this insole applied, the base of the toes on the sole of the foot overlaps the front anti-slip part 3 on the top surface of the insole, and the arch part on the non-slip part 4 fits comfortably and comfortably. , The slip between the sole and the upper surface of the insole is prevented. Therefore, when wearing the footwear, the foot is positioned exactly on the insole, is stable, and is comfortable to wear, and the foot is less tired.

[0008]

【Example】

 An embodiment of a footwear insole according to the present invention will be described with reference to the accompanying drawings. The embodiment shown in FIGS. 1 to 8 is applied to the case where the footwear having the insole of the present invention is worn. An example in which a convex portion and a concave portion are formed corresponding to each other is illustrated, and the one integrally fixed to the bottom body 1 of the sandal is shown in FIGS. 1 and 8.

The insole can be easily manufactured by integrally molding a flexible polyurethane foam having elasticity into a thick plate shape. As shown in FIGS. 1 to 6 and 8, an inclined portion 2 that gradually decreases inward is provided in the peripheral portion of the upper surface of the insole, which is slightly bent upward from the arch portion to the toe portion. The convex part of the bow-shaped front anti-slip part 3 corresponds to the root part of the toes on the sole of the foot that comes into contact when wearing footwear, and the elliptical middle anti-slip part 4 corresponds to the arch part. The convex portions of are formed respectively. Also, when wearing footwear, the curved portion 5 (FIG. 2) corresponding to the inside of the foot is thicker than the portion h corresponding to the outside of the foot as shown by H in FIG. The inner arch should be abutted against it to support it.

As shown in FIG. 1, FIG. 3, and FIG. 5, the middle anti-slip portion 4 is bulged so that it becomes higher gradually from the peripheral portion toward the center. As shown in FIGS. 1 to 3, a shallow recess is formed between the front anti-slip part 3 and the middle anti-slip part 4, and a number of small protrusions are provided on the bottom surface of the recess to form the ventilation part. 6 In this way, when footwear is worn, a gap is created between the sole and the foot, and the breathability is improved. The middle non-slip portion 4 may have a circular shape or any other shape other than an elliptical shape, as long as it fits into the recess of the arch of the foot when footwear is worn.

FIG. 8 shows another embodiment of the insole for footwear of the present invention. In this case, as in the above-mentioned embodiment, the ventilation part 6 is not provided between the front anti-slip part 3 and the middle anti-slip part 4, and a large number of fine holes 7 which do not penetrate are formed on the bulging surface of the middle anti-slip part 4. It is a thing. In this way, when shoes are worn, the breathability is improved and the anti-slip effect can be increased. In addition, in order to increase the anti-slip effect of the middle anti-slip part 4, in addition to the fine pores 7, a large number of thin columnar ones are erected in a standing manner, and the entire tip surface thereof is the same as in the case described above. The shape may be such that the center is swollen such as an elliptical shape.

Since the insole is made of soft polyurethane foam, it can be easily overlaid and fixed on the bottom body 1 made of urethane, rubber, or the like. Sandals can be easily manufactured by simply sandwiching the ends and fixing them together.

Around the upper surface of the insole shown in the above two embodiments, there is provided an inclined portion 2 that gradually decreases inward, so that this is applied to sandals, and the sandals were worn. In this case, the force from the area around the sole contacting the insole is applied inward of the plane of the insole as shown by the arrows in FIGS. Since it fits exactly into the parts and recesses and is stable, no unnecessary force is applied to the soles. Further, the front anti-slip part 3 and the middle anti-slip part 4 can prevent the bottom of the foot from slipping.

By the way, in the middle non-slip portion 4, as shown in FIG. 8, a large number of fine holes 7 are provided, or, as described above, a large number of fine columnar ones are erected so as to stand up, and the footwear is worn. In this case, the arch of the foot can be comfortably stimulated to be suitable as a health sandal. In the embodiment, the case where the main insole is applied to sandals is illustrated, but it is needless to say that the present invention can be applied to slippers and the like.

[0015]

[Effect of device]

 According to the first aspect of the present invention, since the elastic polyurethane foam can be formed only by molding, the structure is simple and the insole can be manufactured at low cost.

According to the second aspect of the present invention, the uneven portion of the sole contacting when wearing the footwear fits perfectly with the convex portion and the concave portion formed by the front anti-slip portion and the middle anti-slip portion. As they overlap, the soles of the feet are stable and comfortable to wear, and it is possible to prevent the feet from getting tired.
