Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to improvement of the surface of sandals, particularly sandals.

(Prior Art) In recent years, sandals have come to be used as casual footwear in Japan instead of traditional geta and zori sandals.

There are various types of sandals, from traditional sandals introduced from Europe and the United States to beach sandals for casual wear.These sandals generally have a sandal base on which the feet are placed, and a sandal base that is attached to the top of the sandal base. It is composed of a string part (including a belt-like part or a strap-like part, which is the same in this specification) that has the role of fixing or locking.

By the way, most sandals are mainly used in the summer, so sweat adhering to the sandal base surface can be easily wiped off, and the open nature of sandals makes it easier for dust to adhere to the sandal base surface. Therefore, in most cases, the surface of the sandal table is made of a vinyl material or a rubber material with a smooth surface so that the surface of the sandal table can be easily wiped off.

(Problem that the invention aims to solve) However, as mentioned above, when the surface of the sandal base is made of vinyl or smooth rubber material, it is difficult to prevent the soles of the feet from sweating or getting wet. Sometimes they become very slippery, and especially in the case of flip-flops that are difficult to secure because of the straps, the sandal base may separate from the sole of the foot every time you walk. In addition, the soles of the feet felt sticky and were not pleasant to the touch.

For this reason, some sandals were made by pasting cloth, etc. on the entire surface of the sandal base to avoid the above-mentioned functional and tactile problems. Since the cloth is sewn with a sewing machine, dirt accumulates in that area, and as mentioned above, the surface cannot be easily wiped, and furthermore, if it gets wet with water, the cloth part does not dry easily. and has the problem of being expensive.

The present invention was developed in view of the above-mentioned current situation, and an object of the present invention is to provide sandals that do not have the various problems mentioned above.

(Means for Solving the Problem) The present invention provides a sandal having a sandal base and a string portion for fixing or locking the foot on the upper surface of the sandal base, and the present invention provides a sandal that corresponds to a part of the concave part or the entire concave part of the sole of the foot. The present invention is characterized in that a protruding portion made of a cushion material and a hygroscopic surface material is formed on the surface of the sandal table.

(Function) Accordingly, the sandal constructed as described above has a protruding portion made of a cushion material and a hygroscopic surface material formed on a portion of the surface of the sandal base that corresponds to a part or all of the concave portion of the sole. Therefore, this hygroscopic surface material and cushion material absorb sweat from the soles of the feet, and even if the sandal base is about to separate from the soles, the protruding hygroscopic surface material and the laces retain their locking action. It is locked by. In addition, sweat on the soles of the feet is absorbed by the hygroscopic surface material and cushion material, so the feel on the soles of the feet is extremely good. Furthermore, the majority of the sandal pad that comes into contact with the sole of the foot is made of conventional vinyl or rubber material, so it can be easily wiped, and even if the sandal pad surface gets wet, it will not absorb moisture. Since only a portion of the surface material is used, it can be dried in a relatively short time.

(Example) Hereinafter, an example of the present invention will be described in more detail with reference to the drawings.

FIG. 1 is a perspective view of a flip-flop according to the present invention. In the figure, 1 is a sandal base, and the surface 1a of the sandal base includes a rubber base surface portion 2 on which small irregularities (not shown) are formed.
On the upper surface of the rubber base surface portion 2 is a protruding portion 3 (see FIG. 2) made of a cushion material 3a and cloth 3b which are pressed together via an adhesive. Both the cushion material 3a and the cloth 3b are made of a hygroscopic material, for example, the cushion material 3a is made of foam rubber,
It is made of a hygroscopic material such as foamed vinyl chloride or foamed polychloroprene, and the cloth 3b is made of a hygroscopic and non-slip material such as pile fabric. Then, a cushion material 3a and a cloth 3b are laminated on the base surface portion 2 of the sandal table via an adhesive, and are integrally bonded by heating and pressing them from both sides. After this adhesion, the surface portion of the base of the sandal table and the boundary portion of the outermost layer of cloth 3a laminated thereon are integrally joined to form a smooth surface. Further, in this embodiment, the protruding portion 3 includes a so-called arch portion, which is a concave portion of the sole of the foot, and a base portion of the toes. The extent of this protrusion is approximately the same as the extent of the depression of the concave portion of the sole.

Further, on the upper surface of the sandal stand 1, a so-called 4 is attached above. In the case of the present embodiment, the surface of this hole 4 is also made of the hygroscopic cloth used for the surface of the protruding portion.

Therefore, the present sandals have the following effects. That is, the protruding portion 3 made of a hygroscopic cushion material and a hygroscopic fiber surface material is provided in the so-called arch region and the root of the toe region, where there are relatively many sweat lines. Even if you scratch your feet, the hygroscopic material absorbs sweat from the soles of your feet, so the soles of your feet won't become sticky.Also, even if the sandal base seems to come off the soles of your feet, the hygroscopic protruding parts 3 and the hygroscopic material will keep your feet from becoming sticky. 4
It is locked by the locking action from above and below and by the small irregularities (not shown) on the rubber base surface portion 2. In addition, sweat from the soles of the feet can be removed by the moisture-absorbing cloth 3 on the surface.
Since the moisture is absorbed by the hygroscopic cushion material 3a through the cushion material 3b, the surface cloth 3b is always kept dry and the soles of the feet feel very good. Furthermore, since the protruding part is arranged on the surface of the sandal base so as to fit into the concave part of the sole of the foot, it fits very well to the foot, and since the protruding part 3 receives stimulation, the foot does not get tired.

Furthermore, the majority of the sandal base that comes into contact with the sole of the foot is made of rubber material, so it can be easily wiped, and even if the sandal base surface gets wet, the moisture-absorbing material part will be wiped clean. Since it is only a portion, it can be dried in a relatively short time.

If the cushion material is impregnated with an athlete's foot medicine or fragrance, a medical effect or an odor eliminating effect can be expected. Similarly, fungicides,
A desiccant may be included.

In the above embodiment, the protruding parts are provided only at the "arch" and "base of the toes," but the protruding parts are provided in the recesses between the toes to match the shape of the sole of the foot. It's okay.

(Effects of the invention) Although the invention has a relatively simple configuration as described above, it can prevent the sandal platform from coming off the sole of the foot, thereby preventing unexpected accidents such as sprains, and always It keeps the soles of your feet in good condition and is stimulated by the hygroscopic material, which not only keeps your feet from getting tired, but is also good for your overall health.

Furthermore, by using a different color or pattern for this hygroscopic material than other materials such as rubber for the surface of the sandal base, fashionability can be created.
