ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to bulletproof equipment for protecting personnel against a projectile fired from a weapon, such as a hand gun, a machine gun or the like. More particularly, the present invention relates to protective bulletproof air bag equipment that can be used for protecting individuals who are particularly at risk of violence by a criminal or terrorist, such as a leading head of state.
2. Description of the Prior Art
In the prior art, conventional bulletproof equipment, such as a bulletproof shield, a bulletproof podium, or the like, has been used to protect key figures from perilous situations, such as sniper fire and terrorist attack. Individuals at risk face particular vulnerability during public appearances and/or at festivities, and such conventional bulletproof equipment can and has been overcome by criminals and terrorists alike.
As such conventional bulletproof equipment has not been capable of providing broad and comprehensive protective capability, there is particular vulnerability in preparation for continuing second and third attacks in public appearances and/or festivities. Considering that such attacks can be the cause of the collapse of social law and order, there is a need for improvement.
In particular, since such existing bulletproof equipment is limited in its employment, development of new special equipment having more comprehensive protective capability is required.
For example, a conventional assault jacket and a bulletproof bag for use by a bodyguard, requires prompt action by the bodyguard in order to effectively cope with a perilous situation; the requires amount of time required for the bodyguard's reaction can be critical.
In addition, a conventional bulletproof podium and table adapted to be used in festivities would provide only a partial concealing space for a targeted individual.
In another solution, backlighting is used as auxiliary means for preventing terrorist's attacks is only in a restrictive place such as an indoor festivity, so that the backlighting disturbs the visibility of a terrorist. However, this solution hardly gives substantial bulletproof effect in a truly perilous situation.
When it is necessary to temporarily set up a soundproof wall or a barrier for accomplishing another purpose, such a sound proof wall or the barrier, requires a long time to set up and take down, and cannot be reused.
In addition to key figures at risk, soldiers sometimes encounter enemy forces and do not have access to cover trenches for protection. Such soldiers are at increased risk to be killed because they are exposed to fire from enemies. Therefore, there remains a need to develop personal portable protective equipment.
SUMMARY OF THE INVENTION
Accordingly, the present invention has been made in order to fulfill the need in the prior art. Accordingly, the present invention provides a novel and unobvious means for protecting key personnel during various public and semi-public festivities.
At least one aspect of the present invention is to provide a barrier means for temporary use in a construction site.
Another aspect of the present invention is the provision of a personal bulletproof shield for being carried by soldiers on a battlefield.
In order to accomplish the above provisions, the present invention is a bulletproof equipment comprising: a bulletproof air bag for protecting a targeted individual from fire of a weapon at a certain ceremony; an air tank for ejecting compressed gas or air into the air bag to inflate the air bag within a predetermined time period by remote control of a user; a high speed fan for feeding air into the air bag to restore the deflated air bag to its original shape when the air bag is punctured by firing from a weapon; a controller for controlling a solenoid operated valve of the air tank, the high speed fan and a driving motor of the bulletproof air bag; and a power supply for applying electric current to the solenoid operated valve, the high speed fan and the driving motor of the air bag.
The bulletproof air bag may be made of high-strength polyethylene having weight not greater than ⅓ of that of Kevlar, which includes Preglight, Dyneema and Spectra.
The bulletproof air bag comprises an inner layer, an outer layer and an intermediate layer disposed therebetween, and the inner layer, the intermediate layer and the outer layer can be made of a windshield cloth, Preglight yarn and Flex, respectively.
The air bag has a front surface similar to that of a blanket and an inverted U-shape in a sectional profile when inflated. In addition, the air bag is capable of protecting a key figure by providing a barrier including the outer layer, the intermediate layer, the inner layer, an air layer, the inner layer, the intermediate layer and the outer layer in this order, upon experiencing impact of a bullet.
