18. The apparatus according to claim 15, wherein after the certain number of rounds has been fired, said element moves to a position that prevents a round from being chambered for firing.

19. The apparatus according to claim 15, wherein said element comprises a shot counter that triggers an action to render said firearm unfit for use upon counting the certain number of rounds.

20. The apparatus according to claim 15, further comprising a processor that controls deployment of said element, said processor being programmable by a user to set the certain number of rounds to a user-selected number.

Description:

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority under 35 USC §119 to U.S. Provisional Patent Application, Ser. No. 60/910,854, filed Apr. 10, 2007, which is incorporated herein by reference.

FIELD OF THE INVENTION

The present invention relates generally to firearms, and particularly to a firearm that is limited in the number of shots that can be fired.

BACKGROUND OF THE INVENTION

Firearms, such as handguns and rifles, are designed for years of reliable service for use by law enforcement personnel and law-abiding citizens.

A disposable, single shot gun has also been proposed. A pistol, known as the WWII FP-45 Liberator Pistol, was originally developed in 1942 for the U.S. Army. It was a single-shot, smooth bore 0.45 caliber pistol. According to the Wikipedia article http://en.wikipedia.org/wiki/FP-45 Liberator, “An interesting fact about the Liberator is that the factories could produce one faster than the weapon could be loaded and fired. The factory turned out a pistol every six or seven seconds whilst loading took about 10 seconds. Another variant of this gun was a two shot version which never made general production. It had two chambers, where one would be fired and then the other slid into position to fire. This version is extremely rare”.

It is important to note that although intended for shooting one round, the WWII FP-45 Liberator Pistol was not rendered incapable of shooting after firing one or more rounds.

SUMMARY OF THE INVENTION

The present invention seeks to provide a limited use firearm, as is described in detail further hereinbelow, and seeks to limit the use of the firearm in manners different from the prior art.

There is thus provided in accordance with an embodiment of the present invention a method for controlling a lifetime of a firearm including limiting a number of rounds a firearm can fire, wherein after a certain number of rounds have been fired, the firearm is rendered incapable of firing more rounds. The certain number of rounds may or may not be predefined. The firearm may be permanently or temporarily rendered incapable of firing more rounds.

After the certain number of rounds has been fired, a portion of a firing mechanism of the firearm may have a mechanical failure and become unfit for use. Alternatively, an element disposed in the firearm may move to a position that prevents a firing mechanism of the firearm from firing a round or prevents a round from being chambered for firing.

In accordance with an embodiment of the present invention the firearm may be provided with a shot counter and the shot counter may trigger an action to render the firearm unfit for use upon counting the certain number of rounds.

A warning may be provided before the certain number of rounds has been fired that the firearm will soon be rendered unfit for firing.

A processor (controller) may be provided that controls deployment of the element that renders the firearm unfit for use (or the shot counter), the processor being programmable by a user to set the certain number of rounds to a user-selected number.

The firearm may be provided with a remote-controllable element that renders the firearm unfit for use after the certain number of rounds.

There is also provided in accordance with an embodiment of the present invention apparatus including a firearm including a firing mechanism and an element which is adapted to prevent the firing mechanism from firing a round after a certain number of rounds has been fired.

DETAILED DESCRIPTION OF EMBODIMENTS

The present invention provides a method for controlling the lifetime of the gun by limiting the number of rounds the firearm can fire. In accordance with an embodiment of the present invention, after a certain number of rounds have been fired, the firearm is rendered incapable of firing more rounds. The certain number of rounds may or may not be predefined. The firearm may be permanently or temporarily rendered incapable of firing more rounds.

In one embodiment, after the certain number of rounds has been fired, a portion of a firing mechanism of the firearm may have a mechanical failure or stoppage and become unfit for use. For example, the sear or breech block may become mechanically fatigued and break, making it impossible to fire the firearm. Alternatively, an element disposed in the firearm may move to a position that prevents a firing mechanism of the firearm from firing a round or prevents a round from being chambered for firing. As another alternative, an element disposed in the firearm may move to a position that prevents a firing mechanism of the firearm from firing after a specific pre-programmed date.

In accordance with an embodiment of the present invention the firearm may be provided with a shot counter and the shot counter may trigger an action to render the firearm unfit for use upon counting the certain number of rounds.

For example, the shot counter can be used to provide the firearm with a limited and/or programmed life expectancy. As another example, the shot counter can limit the use of the firearm to a certain amount of rounds, and then can be released again for additional rounds, such as by an authorized person resetting or releasing the shot counter.

The shot counter can limit the shots according to a certain date. In all these examples, the shot counter can cause limited use of the firearm as described above (e.g., a portion of a firing mechanism of the firearm having a mechanical failure or stoppage, the sear or breech block becoming mechanically fatigued, element disposed in the firearm moving to a position that prevents a firing mechanism of the firearm from firing a round, etc.) by being mechanically or electrically linked to an appropriate portion of the firearm (sear, breech block, firing mechanism, etc.).

A warning may be provided before the certain number of rounds has been fired that the firearm will soon be rendered unfit for firing.

A processor (controller) may be provided that controls deployment of the element that renders the firearm unfit for use (or the shot counter), the processor being programmable by a user to set the certain number of rounds to a user-selected number.

The firearm may be provided with a remote-controllable element that renders the firearm unfit for use after the certain number of rounds.

There is also provided in accordance with an embodiment of the present invention apparatus including a firearm including a firing mechanism and an element which is adapted to prevent the firing mechanism from firing a round after a certain number of rounds has been fired.

Other possible applications of the invention include a person purchasing a firearm for a certain number of rounds and then returning the firearm to the manufacturer for service.

Another possibility includes limiting a shooter to usage of the firearm until a certain age (e.g., 75), whereupon the firearm is rendered unfit for use until the person passes a sight/health examination, or simply blocking the gun after a specific date.

It is appreciated that various features of the invention which are, for clarity, described in the contexts of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the invention which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable subcombination.
