ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a device for reducing the danger of harm caused by the accidental discharge of a bullet from a firearm. In particular, the present invention is especially useful for reducing the danger of harm caused by the accidental discharge of an armour-piercing bullet from a firearm.
BACKGROUND OF THE INVENTION
The problem of firearm-caused accidents due to the accidental discharge of bullets is a serious one, and has found no real solution beyond exhortatory 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 safety catch, which cannot always be relied upon under field conditions.
DISCLOSURE OF THE INVENTION
It is therefore an object of the present invention to provide a device attachable to various types of firearms, such as single-shot, semi-automatic and automatic weapons, which will reduce the danger of harm caused by the discharge of a bullet from a firearm.
It is a further object of the present invention to provide such a device which is especially suitable for use with armour-piercing cartridges.
It is a still further object of the present invention to provide a device capable of reducing the danger of harm caused by discharge of an armour-piercing bullet from a firearm, however, allowing the continuation of firing of armour-piercing bullets without interruption.
A still further object of the invention is to provide a device for reducing the danger of harm caused by the accidental discharge of a-bullet-from a firearm, incorporating an indicator for specifying that the device has already fulfilled its function and should be replaced by a new one.
According to the present invention, there is therefore provided a device for reducing the danger of harm caused by the accidental discharge of a bullet from a firearm, 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; an impact disc having upper and lower surfaces, slidably disposed in the cavity of said tubular body; an energy-absorbing and storing means interposed in said tubular body between the upper surface of said impact disc and an abutting means, said absorbing and storing means acting on said impact disc to maintain contact with said abutting means inside said body, and a body made of a material at least as hard as the material of the bullets to be used with the firearm, said body being affixed at the lower surface of said impact disc, for substantially preventing a bullet from piercing through said impact disc; whereby, upon the discharge of a bullet, said bullet impacts said body, transferring some of its kinetic energy to said energy-absorbing means and thereby reducing the danger of harm caused by the accidental discharge of said bullet from said firearm.
