BALLISTIC SHIELD

 The present invention relates to a bulletproof shield, and more particularly, to a bulletproof shield which can protect bullets emitted from a firearm provided in an exhibition by using the rotational force of a roller and prevent secondary damage It is about a bulletproof shield.

In general, war refers to the act or condition of two or more conflicting states or groups attempting to enforce their will by using various means, including military power, between the groups.

Modern soldiers are wearing battalions and fighting to defend against enemy attacks. Body armor can be divided into two types of body armor and steel armor.

In the case of textile armor, it is mostly designed to protect the bullet. In the case of steel armor, it is designed to protect the body. Textile armor is a body armor that prevents penetration by blocking the rotation of the bullet, and the body armor has a structure that protects the body by inserting steel plate.

The above-described body armor is manufactured in a jacket shape to protect only the parts where important organs of the body are concentrated, in order to protect only the important organs of the wearer. However, a conventional jacket-shaped body armor was vulnerable to attack by other parts of the body except for the body part, and thus it was impossible to completely defend the enemy attack.

And modern infantry tactical weapons vary depending on the illness, but most of them carry guns (personal firearms), grenades, grenade launchers, cremora, pistols and bayonets. Since most of the infantry combat operations are attacking weapons that attack the attack site, it is somewhat unreasonable to defend against enemy attacks only with the armor worn as a defensive weapon, resulting in many casualties and casualties.

 In addition, modern infantry tactics are urgently needed to spread the tactical military equipment necessary to bring advantage of the ever-changing battle situation.

In consideration of the above situation, a shield for bulletproof is being developed to protect the entire body in a combat situation.

However, since bullets have been created under the premise that bullets should not penetrate through the shield, most bullet-proof shields are quite large in size and weight, and when equipped with shields and combat, there are a number of limitations .

In addition, bullets may bounce without being struck by a shield. Especially in a crowded space, a bullet may bite to a nearby friend without being struck by a shield, which may result in death.

Finally, even if the warhead is rarely recovered or recalled, the recovery rate is very low, which is a waste of valuable resources.
