【発明の属する技術分野】
本発明は耐刃防護板に関する。詳しくは、身体の危険にさらされる業務に就労する警察官、ガードマン等が着衣の下に着用し、刃物、アイスピック等による攻撃に対して防護を行うことができる耐刃防護板に関する。
【0002】
【従来の技術】
従来、警察官等が刃物による攻撃の危険から身体を防護するため、平常衣の下に装着することができる耐刃防護板が開発されている。
例えば、特開昭58−19700号公報で開示された防弾刃下着の提案がある。この発明は防刃板状対として防刃子相互を1層に展開し、相互の防刃子を2種類の形状の連結子によって連結する構成になっており、防刃子が一部では連結子と2層構造であるが、防刃機能は防刃子の1層構造としてしか働かないものである。この防弾刃下着においては、防弾機能はかなり満足するものであるが、刃物に対する防刃機能の面で十分な機能を達成しょうとすると極端に着用性が低下するか、あるいは着用性を下げないために人体へのフィット性に留意した物は分割小片で構成する必要があるので各小片の隙間が細刃に対して無力であった。
【0003】
そこで、防刃機能と着用性の両方を満足するものとして特公平6−50240号に開示された耐刃防護板が開発されている。この耐刃防護板1は、図9(b)の一部拡大図及び同図(c)の断面図に示されるように、樹脂板(例えば厚さ2mm程度のポリカーボネート)で形成され、複数の連結孔2及び複数の通気孔(図示省略)が形成された六角形状の複数の防刃用小片3を、それぞれ周辺を突き合わせて隙間のない状態に敷きつめて表層4とし、同様な形状の樹脂板(例えば厚さ1.5mm程度のガラスフアイバ入り66ナイロン)の小片5((b)図では点線で示す)群から成る裏側層6とを、表層及び裏側層のそれぞれの突き合わせ部が重ならないように重ね、リベット7により表層4及び裏側層6を接続し図9(a)の如く所定の形状に組み立てたものである。
【0004】
【発明が解決しようとする課題】
上記の耐刃防護板は防刃機能と着用性の両方を満足するものであるが、樹脂板に耐防刃性に必要な厚さを持たせるため重量が重くなるという問題がある。
【0005】
本発明は上記従来の問題点に鑑み、防刃機能と着用性の両方を満足し、且つ重量の軽い耐刃防護板を実現することを目的とする。
【0006】

BACKGROUND OF THE INVENTION
The present invention relates to a blade-proof protective plate. More specifically, the present invention relates to a blade-resistant protective plate that can be worn under the clothing of police officers, guardmen, and the like who are engaged in work exposed to physical hazards, and can protect against attacks by blades, ice picks, and the like.
[0002]
[Prior art]
Conventionally, in order to protect the body from the danger of attack by a blade by a police officer or the like, a blade-resistant protective plate that can be worn under a normal garment has been developed.
For example, there is a proposal of a bulletproof blade underwear disclosed in Japanese Patent Laid-Open No. 58-19700. The present invention has a configuration in which the blade protection blades are developed as a pair of blade protection blades in a single layer, and the blade protection blades are connected by two types of connectors, and the blade protection blades are partially connected. Although the blade and the two-layer structure, the blade-proof function works only as a one-layer structure of the blade-proof element. In this bulletproof blade underwear, the bulletproof function is quite satisfactory, but if you try to achieve sufficient function in terms of the blade-proof function for the blade, the wearability will be extremely reduced or will not decrease In addition, since it is necessary to configure the object in consideration of the fit to the human body with divided pieces, the gap between each piece is ineffective against the fine blade.
[0003]
Therefore, a blade-resistant protective plate disclosed in Japanese Patent Publication No. 6-50240 has been developed as satisfying both the blade-proof function and the wearability. As shown in the partially enlarged view of FIG. 9B and the cross-sectional view of FIG. 9C, the blade-resistant protective plate 1 is formed of a resin plate (for example, polycarbonate having a thickness of about 2 mm), and has a plurality of couplings. A plurality of hexagon-shaped blade-proof pieces 3 each having a hole 2 and a plurality of ventilation holes (not shown) are arranged in a state where there is no gap with each other butting the periphery, and a resin plate having a similar shape ( For example, a back side layer 6 consisting of a group of small pieces 5 (shown by dotted lines in FIG. 5 (b)) of glass fiber-filled 66 nylon having a thickness of about 1.5 mm is not overlapped with the respective butted portions of the surface layer and the back side layer. The top layer 4 and the back side layer 6 are connected together by rivets 7 and assembled into a predetermined shape as shown in FIG. 9A.
[0004]
[Problems to be solved by the invention]
The above-mentioned blade-resistant protective plate satisfies both the blade-proof function and the wearability, but there is a problem that the resin plate has a thickness necessary for blade-proof resistance and the weight increases.
[0005]
In view of the above-described conventional problems, an object of the present invention is to realize a blade-resistant protective plate that satisfies both the blade-proof function and the wearability and is light in weight.

【The invention's effect】
According to the blade-resistant protective plate of the present invention, because it is made of a light metal such as duralumin, the weight is lighter than the conventional blade-resistant protective plate, the strength is large, and the resistance to the blade is strong. Anti-slip ribs prevent the blade from slipping and improve safety. In addition, it is possible to prevent metal noise by applying the coating, and it is possible to cope with sweating by providing a large number of small holes for ventilation. Furthermore, the curvature of the metal plate piece and the rivet caulking are loosened, so that the portion is flexible, and the wearability is improved due to good fit to the human body.
