Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a bulletproof shield used by police, the Self-Defense Forces, and the like.

[Conventional technology and its problems]

Since the bulletproof shield described above is to be held in the hand or leaned forward to protect itself from firing, it must be able to reliably block the penetration of bullets.

Therefore, the conventional bulletproof shield is mainly made of duralumin, but it is relatively heavy, inconvenient to carry, and has a problem in usability.

Also, the bulletproof shield is usually formed in a cylindrical shape in order to weaken the impact force of the fired bullet, but if duralumin is used as the material, the bullet hitting the bulletproof shield will bounce back and forth in all directions, There was a risk of injury.

[Purpose of device]

Therefore, an object of the present invention is to solve the above-mentioned inconvenience and to provide a bulletproof shield which is lightweight and easy to handle and excellent in safety.

[Constitution of device]

In order to achieve the above-mentioned object, the present invention provides a shield body having a three-layer structure in which a plurality of high-strength fiber layers are laminated on the surface of a substrate made of titanium, and a synthetic resin layer is further provided on the surface of the shield body in a vertical direction. To form a plurality of divided bodies, connect the divided bodies in a foldable manner, and rotatably attach an arm to one of the divided bodies and engage the arm with the other divided body. A structure with a joint is used.

〔Example〕

An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 to 4, the shield body 1 is a three-layer structure in which a plurality of high-tensile fiber layers 3 are laminated on the surface of a substrate 2 made of titanium, and a synthetic resin layer 4 is further provided on the surface thereof. Made of structure.

In the embodiment, aramid fiber (trade name Kevlar) is used as the high-tensile fiber layer 3, and polyvinyl chloride (PVC) is used as the synthetic resin, but the high-tensile fiber layer 3 and the synthetic resin layer 4 are used. Is not limited to this.

The shield body 1 is divided into upper and lower halves, and an upper divided body 5a and a lower divided body 5b are foldably connected by a hinge 6, and an arm 7 attached to the back surface of the lower divided body 5b is pin 8
And the notch 9 formed on one side of the tip of the arm 7 is engaged with the engaging pin 10 projecting on the rear surface of the upper divided body 5a and screwed with the engaging pin 10. By tightening the nut 11, the shield body 1 can be held in a flattened state.

As shown in FIG. 3, when the handle 12 is attached to the rear surface of the shield body 1 and the upper portion of the extendable support leg 14 is rotatably connected to the bracket 13 attached to the upper rear portion of the shield body 1, You can obtain the usage state you have and the usage state leaning forward.

〔effect〕

As described above, the present invention has a structure in which a high-tensile fiber layer is laminated on the front surface of a substrate made of titanium, and a synthetic resin layer is provided on the front surface, so that it is extremely lightweight and excellent in usability, and the surface layer is Since it is a synthetic resin layer, when a fired bullet hits it, it can bite inside and prevent the bullet from bouncing back. For this reason, it is safe without harming a third party, and since the high-strength fiber layer is provided on the back of the synthetic resin layer, it absorbs the impact force of the bullet that bites inside, and the bullet is almost You can take it with certainty. Even if a bullet penetrates the high-tensile fiber layer, the substrate provided on the back is made of titanium, so that the bullet can be securely prevented from penetrating, which is extremely safe.

Further, since the bullet can be reliably received, it is possible to check the rifle mark from the ejection of the bullet, and to know the type of firearm used, the presence or absence of past use, the owner, and the like.

Furthermore, since the shield body is foldable, it is convenient for carrying and storing, and the shield body can be held in the expanded state by deploying the shield body in a flat plate shape and engaging the arm with the engaging part. Therefore, it is possible to obtain an extremely safe usage state.
