The present invention relates to a bulletproof kit, and more particularly to a bulletproof kit having improved multi-tank protection ability.

Bulletproof bodies are generally used to protect human bodies or vehicles from various ballistics such as bullets. In the conventional bulletproof body, a synthetic fiber layer composed of several layers was used. Recently, a ceramic material having a high hardness is widely used for bulletproof bodies.

1 is a cross-sectional view showing a conventional bulletproof body 10 using a ceramic.

Referring to FIG. 1, a conventional bulletproof body 10 includes a fiber reinforced plastic (FRP) composite material 11 and a ceramic ball 12. In the FRP composite material 11, there are a plurality of ceramic balls 12 having a spherical shape. The ceramic ball 12 has a stronger hardness than the warhead. When the warhead hits the ballistic body 10 of the related art, the warhead collides with the ceramic ball 12 in the FRP composite material 11. Since the ceramic ball 12 is harder than the warhead, the warhead collided with the ceramic ball 12 is crushed. That is, the kinetic energy of the warhead is consumed by the collision of the warhead and the ceramic ball 12. Through such a process, the conventional bulletproof body 10 has a protective effect.

However, the ceramic material has brittle characteristics that when the force is applied beyond the elastic limit, it is destroyed without permanent deformation or only a small part of the permanent deformation occurs. Therefore, the ceramic ball 12 collided with the warhead may be crushed, and thus, when a plurality of warheads hit the ballistic body 10, the protection function could not be maintained.

Recently, warheads made of iron or tungsten with improved hardness have been used. These warheads are of greater hardness than the ceramic balls 12 used in conventional ballistic bodies. As described above, there is a problem in that the ballistic body 10 using the conventional ceramic ball 12 cannot prevent penetration of the warhead with respect to the warhead having improved hardness. A ceramic material having a hardness greater than that of the warhead having improved hardness may be used, but the higher the hardness, the higher the price of the ceramic is, thereby increasing the manufacturing cost of the bulletproof body.

It is a main object of the present invention to provide a bulletproof kit having improved multi-tan protection capability.

Bulletproof kit according to the present invention, the base layer for maintaining the shape; And a plurality of high compression elastic members distributed in the base layer, wherein the high compression elastic members comprise a high compression elastic material and a packing portion surrounding the surface of the high compression elastic material.

In the present invention, the high compression elastic material may be made of high elastic rubber.

In the present invention, the high compression elastic member may have a polyhedral shape.

In the present invention, the high compression elastic member may have a spherical shape.

In the present invention, the high compression elastic member may be uniformly distributed in the base layer.

In the present invention, the base layer may be made of plastic.

In the present invention, the matrix layer may be made of a resin.

Hereinafter, the present invention will be described in detail with reference to embodiments of the present invention shown in the accompanying drawings. But. The present invention may be modified in various other forms, and the scope of the present invention is not limited to the following embodiments. The embodiments of the present invention are provided to enable those skilled in the art to more fully understand the present invention. Accordingly, the shape and size of elements in the drawings may be exaggerated for clarity, and the elements denoted by the same reference numerals in the drawings are the same elements.

2 is a cross-sectional view showing a bulletproof kit 100 according to an embodiment of the present invention.

2, the bulletproof kit 100 includes a base layer 101 and a high compression elastic member 104.

The base layer 101 maintains the shape of the bulletproof kit 100. Therefore, the shape of the bulletproof kit 100 may have a plate shape or some surfaces may be bent or curved depending on the shape of the base layer 101. The base layer 101 may be made of plastic or resin. Resins include thermosetting resins such as epoxy and phenol, or thermoplastics such as polyester, polyurethane, acrylic, ABS, polyethylene, polypropylene, etc. Resin, such as resin, can be used.

The high compression elastic member 104 is distributed in a large number in the base layer (101). It is preferable that the plurality of high compression elastic members 104 are uniformly distributed in the matrix layer 101. The high compression elastic member 104 may have a spherical shape, but the present invention is not limited thereto and may be a polyhedron. The high compression elastic member 104 is composed of a high compression elastic material 103 and the packaging portion (102). The high compression elastic material 103 may be a rubber of high elasticity.

The high compression elastic material 103 is surrounded by the packaging portion (102). The packing unit 102 may be any material that can keep the high compression elastic material 103 in an elastically compressed state in the packing unit. For example, the resilient material 103 may be made of various materials such as synthetic resin, metal, special fiber, etc. which can be easily obtained by those skilled in the art related to the bulletproof kit. The high compression elastic material 103 in the packing part 102 is highly compressed, and when the bullet hits the high compression elastic member 104, the packing part is in contact with the bullet or adjacent to the hit part of the high compression elastic member 104 ( A portion of the 102 is crushed to release the high compression elastic material 103 that has been highly compressed in the packaging 102. Since the direction in which the high-compression elastic material 103 is discharged is opposite to the direction in which the bullet is advanced, the high-compression elastic material 103 exerts a force in the direction opposite to the direction in which the bullet is traveling, thereby reducing the speed of the bullet and causing the bullet to bounce off. Causes the bullet to change direction.

3 to 5 are diagrams schematically showing the action when the bullet holes 110 hit the bulletproof kit 100 of FIG. FIG. 3 is a view showing the bullet holes 110 traveling toward the bulletproof kit 100. FIG. 4 is a view showing the bullet holes 110 colliding with the bulletproof kit 100 at the first time, and FIG. A portion of) is crushed to show that the high compression elastic material 103 is released.

Referring to FIG. 3, the bullet 110 fired from the firearm proceeds toward the bulletproof kit 100. A represents the traveling direction of the bullet 110. Referring to FIG. 4, the bullet holes 110 collide with the bulletproof kit 100. The impact force is transmitted to the high compression elastic member 104 by the collision of the bulletproof kit 100 and the bullet holes 110. As shown in FIG. 5, a part of the packing part 102 is crushed by the impact force. The highly compressed elastic material 103 that is highly compressed in the packing part 102 is released through the crushed packing part 102. The discharge direction B of the high compression elastic material 103 is opposite to the traveling direction A of the bullet box 110. Accordingly, the high-compression elastic material 103 is released to apply a force in the direction (B) opposite to the traveling direction (A) of the bullet (110) to slow down the speed of the bullet (110), or bounce off the bullet (110) or Change the direction of the bullet 110 to increase the protective function.

When the size of the high compression elastic member 104 is smaller than that of the bullet 110, a large number of high compression elastic members 104 are crushed when the bullet 110 collides with the bulletproof kit 100, and the bullet is shot on the bullet 104. By transmitting a force in the direction (A) and the opposite direction (B) of 110 can further enhance the protection function.

In addition, by distributing a large number of high-compression elastic member 104 in the base layer 101, even if one high-compression elastic member 104 is broken, the other high-compression elastic members 104 receive bullets continuously by performing a bulletproof function. Even in the case of multi hits, a multi-protective effect can be secured.

As described above, in the present invention, a part of the packing part 102 is crushed so that the high-compression elastic material 103 in the packing part 102 is released in a direction opposite to the traveling direction A of the tanza 110 (B). As it maintains its function, it can maintain a high protective function even if the hardness of the bullet increases.

The present invention can maintain a high protective function even for a bullet having a high hardness, and can improve a multi-tan protective function.

It is intended that the present invention not be limited by the foregoing embodiments and the accompanying drawings, but rather by the appended claims, and that various changes, substitutions, and alterations can be made hereto without departing from the spirit of the invention as defined in the appended claims. It will be apparent to those skilled in the art that changes may be made.
