Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to cloth shoes, and more particularly to dustproof safety shoes suitable for use in 11IiK clean rooms and the like.

In recent years, there has been a strong need for clean rooms in various industries such as semiconductor product manufacturing, precision industry, pharmaceutical industry, oil refining industry, food industry, printing industry, film manufacturing industry, painting industry, and in the medical field. It has been demanded.

In particular, semiconductor products such as integrated circuits (RC) and large-scale integrated circuits (L8I) are overmanufactured! , extremely strict cleanliness is required, and how to keep the inside of a clean room clean is an important issue for improving product yield.

Conventionally, in order to prevent contaminated particles from entering a clean room from outside, a Hepa filter was used to supply clean air into the room, and an air shower was used to remove dust and bacteria from the clothes of occupants. In addition, dust-free clothing and shoes are also used.

Among these efforts, various efforts have been made to make shoes for indoor use dust-free, and the combination of protective foot covers and vinyl sandals may be considered. However, since sandals tend to generate dust, they are not only undesirable in terms of dust-free properties, but also have drawbacks such as extremely poor workability since they are separate from the foot cover.

Therefore, it may be possible to work without using sandals and with only foot covers, but since foot covers are simply made of thin cloth, they are slippery and there is a high possibility of injury to workers, and they are made of vinyl. Since the user walks on the floor with only the foot covers on, the foot covers themselves are subject to severe fatigue, which in turn causes the problem of dust generation.

Therefore, an object of the present invention is to address the above-mentioned problems and to provide cloth shoes such as dust-proof safety shoes that are not only dust-proof but also have excellent safety, workability, and durability.

To achieve this objective, the cloth shoe according to the invention is characterized in that the sole and the foot cover are integrated into one another.

Hereinafter, the present invention will be further explained according to an embodiment shown in the drawings.

FIG. 1 and FIG. 2 are a perspective view and a front view, respectively, showing a dustproof safety shoe which is an embodiment of the cloth shoe according to the present invention.

In this embodiment, the sole 10 of the dust-proof safety shoes and the bag-shaped foot cover 12 that covers the foot of the worker have a mutually integrated structure. The sole 10 is made of sponge rubber mixed with conductive silica, has a thickness sufficient to suppress fatigue of the worker's feet, and has an anti-slip groove 14 formed on the back surface. There is. On the other hand, the foot cover 12 has conductive fibers 1 made of carbon and synthetic fibers such as polyester.
6 woven vertically. These soles
In order to connect O and the foot cover 12, in this embodiment, the third
As shown in the figure, a conductive adhesive 18 is used.

- Therefore, in this embodiment, a conductive structure is formed from the foot cover 12 through the adhesive 18 to the sole 10, which prevents the foot cover 12 from being charged and attracting dust, which improves the It provides excellent dust resistance and also prevents explosions caused by static electricity.

A zipper 20 for opening and closing is sewn on the front side of the foot cover 12 from the upper end of the foot cover 12 to near the toes with sewing thread 21 to facilitate washing of the inside of the foot cover 12. ing.

41, the zipper 20 is provided close to the toe, making it easy to put on and take off the shoes and wash them.In addition, it is possible to put in and out the sponge insole 22 for shoes inside and out of the foot cover 12. This has the great advantage of being very easy to do.

Also, the upper end portion of the foot cover 12 is an ankle portion.

The VC, which is approximately midway between the instep and the toe (near the upper part of the arch), is provided with narrowed portions 24, 26 and 28, respectively. These aperture parts 24.26
．． Reference numeral 28 is used to hold the foot cover 12 so that it does not slip off the worker's feet during work, and has a structure in which a rubber cord (not shown) is sewn inside.

According to this embodiment, since the sole 10 and the foot cover 12 are integrated, it not only has good dust resistance, but also safety and workability, and is very durable and comfortable to wear. be.

That is, in this embodiment, the feet of the worker wearing the shoes come into contact with the floor through the thick sole 10 (and the insole 22), so they are comfortable to wear (and there is less fatigue on the feet, and the feet are less slippery). Not only is it safe, there is no risk of falling over or getting injured by hitting other objects, but the one-piece structure makes it easy to work with.Furthermore, the foot cover 12 does not come into direct contact with the floor, so the foot cover 12 does not come into direct contact with the floor. It is also possible to prevent dust from being generated from the cover 12 and increase durability.

Furthermore, in this embodiment, the foot cover 12 is woven with conductive fibers 16, and the adhesive 18 and sole 10 are woven into the foot cover 12.
The foot cover 12 also contains conductive material.
It is possible to prevent static electricity from being charged to the foot cover 12, and to prevent dust from adhering to the foot cover 12 due to static electricity. As a result, it is possible to prevent dust attached to the leg covers 12 from being brought into the clean room from the outside, and also to prevent the risk of explosion due to static electricity.

In addition, in this embodiment, the leg cover 12 has a constricted portion 2.
4.26.28, the foot cover 12 is firmly held on the worker's foot, so there is no slippage and the work is very easy.

Moreover, since the fastener 20 is provided from the upper end of the front side of the foot cover 12 of this embodiment to near the toe, it is not only very easy to wash the foot cover 12, but also very easy to put on and take off the insole 22. can be done easily and conveniently.

Note that the sole 10 and the foot cover 12 may be sewn together with thread, preferably conductive thread.

Furthermore, the sole 10 can be made of a material other than the above-mentioned sponge rubber, and the foot cover 12 can also be made of a material other than polyester, such as polyamide synthetic resin. The conductive fibers 16 can also be made of stainless steel, for example, and the sole 10 and the adhesive 18 can also be made of stainless steel.
The conductive material contained in the material may also be other than silica. Although the safety shoes of the present invention may be used exclusively for the left and right sides, from the viewpoint of compatibility, it is preferable that the safety shoes have a sole shape that can be used for both the left and right sides.

As explained above, according to the present invention, cloth shoes with good dustproof properties can be obtained, which improves safety and workability.

Excellent effects can also be obtained regarding durability.
