ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a device for preventing the accidental discharge of a bullet from a firearm. More particularly, the present invention relates to a device for preventing the accidental discharge of a bullet, suitable for use with blank or drill cartridges.
BACKGROUND OF THE INVENTION
The problem of firearm-caused accidents due to the accidental discharge of bullets is a serious one, particularly in the armed forces, and has found no real solution beyond warning and disciplinary efforts, the effects of which are unfortunately rather limited. The basic cause of these accidents is obviously the “cartridge in the chamber,” which devolves the entire responsibility for safety upon the slender shoulders of the safety catch, which cannot always be relied upon under field conditions. Still, while the “cartridge in the chamber” is regarded as a serious breach of discipline under ordinary circumstances such as basic training and routine guard duties, the loaded chamber cannot be avoided in certain security operations, such as patrolling in hostile territory, and the like. This problem is even more compounded when blank cartridges are used during training or field exercises and a real, or “live,” cartridge is accidentally loaded.
There are known devices utilizable with blank cartridges for facilitating the cocking of a firearm; such devices are attached to the barrel of the firearm by means of a screw traversing the barrel for the purpose of arresting the gases produced when a cartridge is fired. Such devices pose a real danger to the user and to the firearm itself, in the event that the firearm's magazine was loaded with a “live” cartridge and a bullet is accidentally fired, hitting the screw.
SUMMARY OF THE INVENTION
It is one of the objects of the present invention to offer a solution to the above problems by providing a device attachable to various types of firearms: single-shot, semi-automatic and automatic, which will prevent the discharge of a bullet from the firearm without causing any damage thereto.
It is a further object of the present invention to provide such a device which is especially suitable for use with blank cartridges.
According to the invention, the above objects are achieved by providing a device for preventing the accidental discharge of a bullet from a firearm, suitable for use with blank cartridges, said device comprising attachment means adapted to engage the muzzle end of a firearm barrel, a substantially tubular body having a cavity and coaxially attachable at one of its ends to said barrel via said attachment means, a bullet-pierceable insert having a portion traversing the axis of said barrel and tubular body; an impact disk slidably disposed in the cavity of said tubular body, energy-absorbing and storing means interposed in said tubular body between said impact disk and an abutting means, acting on said impact disk to maintain contact with said insert inside said body, wherein, upon the discharge of a bullet, said bullet pierces said insert and hits said impact disk, transferring some of its kinetic energy to said energy-absorbing and storing means, and is thereby prevented from being discharged from said firearm.
