とから、これらの危険物を踏み付けることによつ
て、けがをすることが多々あり、その危険を防止
するため、底部を補強した踏抜き防止ゴム底履物
が用いられている。b. Conventional technology When working at a construction site, etc., there are dangerous objects such as metal pieces, glass fragments, nails, etc. scattered around, so there is a risk of injury from stepping on these dangerous objects. In order to prevent this danger, rubber-soled footwear with reinforced bottoms to prevent punctures is used.
ｃ 考案が解決しようとする課題
このような工事現場等で作業をする際に使用す

合、ゴム製表底と金属板が剥離する虞れがある。C. Problems that the invention aims to solve Conventionally, rubber-soled footwear that prevents punctures used when working at construction sites, etc., has a metal plate placed on the bottom of the footwear to protect the feet from dangerous substances. ing. However, since the warpability of the sole of the footwear is reduced, if a strong bending force is applied to the sole, there is a risk that the rubber outsole and the metal plate will separate.
そこで、金属板の指側に、波状または鋸歯状の
凹凸部を形成して、指先の屈伸性を向上させた履
物が用いられている（実開昭58−41205号公報）。
しかしながら、かかる履物では、耐踏抜き性を向
上させるため金属板の厚みを十分に、通常約１mm
採ると、屈伸性が低下するとともに重量が大きく
なり、一方、金属板の厚みを薄くすると、くぎ等
が金属板を貫通する虞れが生じ、危険であつた。 Therefore, footwear is used in which wavy or serrated uneven portions are formed on the finger side of a metal plate to improve the flexibility of the fingertips (Japanese Utility Model Publication No. 58-41205).
However, in such footwear, the thickness of the metal plate is usually about 1 mm to improve the resistance to stepping.
If the thickness of the metal plate is reduced, the flexibility and extensibility will decrease and the weight will increase.On the other hand, if the thickness of the metal plate is reduced, there is a risk that nails or the like will penetrate the metal plate, which is dangerous.
本考案は、上記事情に鑑みてなされたもので、
耐踏抜き性能の向上を図り、かつ十分な屈伸性を
有する踏抜き防止ゴム底履物を提供することを目
的とする。 This invention was made in view of the above circumstances,
It is an object of the present invention to provide rubber-soled footwear that improves punch-through resistance and has sufficient flexibility.

を履物の底部に内装したことにある。d Means for Solving the Problems In order to solve the above problems, the present invention forms a thin metal plate in the shape of a foot that does not impair the flexibility of the sole of the footwear, and extends the plate surface of the metal plate corresponding to the toe side in the longitudinal direction. , a corrugated or sawtooth-like bending process is applied to form an uneven surface of the same pitch, and a plurality of metal plates each having an uneven surface of the same pitch are formed so that the tops and bottoms of the uneven surfaces do not face each other. The metal plates are arranged in a staggered manner and filled with synthetic resin or synthetic rubber between the metal plates to form an insole plate, and the insole plate is installed inside the bottom of the footwear.
ｅ 作用

向を変えながら、応力の集中を防止する。e Function: The part of the thin metal plate formed in the shape of a foot that corresponds to the toe side is bent in a wavy or serrated pattern, so even when multiple pieces are used, the sole of the footwear can be warped freely. . Furthermore, even if a sharp object such as a nail is stepped on, the two metal plates change the direction of the sharp object from entering the device, thereby preventing concentration of stress.

る。 1 and 2, reference numeral 1 denotes rubber-soled footwear, which includes an outer cover 2 forming the outer shape of the footwear;
A rubber shoe sole 3 provided on the bottom surface, an insole plate 4 delivered inside the shoe sole 3, a synthetic resin layer 5 arranged on the top surface of this insole plate 4, and a rubber shoe sole 3 provided on the innermost side of the footwear. It is composed of an inner cover 6 provided therein. As shown in FIG. 3, the insole plate 4 includes a plurality of metal plates 7 each having a thickness of approximately 0.25 mm formed in the shape of a foot, and a portion having a thickness of approximately 0.2 to 1.2 mm filled between the metal plates 7.
The filling layer 8 is made of synthetic rubber or synthetic resin. The metal plate 7 is bent in a wavy or serrated manner along the longitudinal direction of the plate surface corresponding to the toe side to form an uneven surface 9 of the same pitch. 7 are arranged at a predetermined distance from each other so that the top 9 1 and bottom 9 2 of the uneven surface 9 having the same pitch are shifted in the longitudinal direction so that they do not face each other. A synthetic resin layer 1 is provided on the upper and lower sides of the wavy or sawtooth portion of the insole plate 4.
0 is formed. Further, a protective member 11 is installed around the tip of the footwear and around the heel.

される危険がない。 According to the footwear having the above structure, the tip of the metal plate 7 made of a thin steel plate is formed in a wavy or serrated shape, so it has excellent flexibility and is lightweight, making it suitable for walking at work sites, etc. There is. Even if a dangerous object such as a nail is stepped on, the nail is oriented along the corrugated uneven surface 9 of the metal plate 7 and does not hit the metal plate 7 at right angles, so there is little risk of it penetrating the metal plate 7. . In addition, the uneven surfaces 9 of the same pitch of each metal plate 7 are staggered so that their tops 9 1 and bottoms 9 2 do not face each other. In this case, the friction at the penetration part of the first metal plate 7 acts, causing the second metal plate 7 to bend the direction of the nail, and there is a risk that the two metal plates 7 will be penetrated at the same time. There is no.
