Self-powered extensible projectile launching police baton
First Claim
1. A device comprising:
- a first elongate member having a hand grip portion;
a second elongate member reciprocatively disposed in said first member in a manner to define a telescopic arrangement, said second member having an inboard end disposed in said first member and an outboard end, said second member being adapted to be driven by gas pressure in said first member so as to be displaced within said first member and to extend out of said first member by a predetermined distance;
a third member connected to the outboard end of said second member;
projectile receiving means for receiving a projectile, said projectile receiving means comprising a hollow portion in the outboard end of said second member;
a spring disposed in said first member for biasing said second member toward a fully retracted position wherein the amount of projection of said second member out of said first member is minimized; and
a source of gas under pressure which is responsive to a manually manipulatable member disposed on said hand grip portion, said source being fluidly communicated with said first member for supplying a gas under pressure thereinto and for producing the gas pressure which causes said elongate member to extend out of said first elongate member.

Abstract
A baton-like device is provided with a hollow telescopic ram or bolt member which can be driven to extend out of a barrel or trunk portion of the baton. The driving force is produced by a source of gas under pressure, which in preferred embodiments, takes the form of explosive cartridges and which can be repeatedly and automatically operated in a manner similar to an automatic shot gun. The force with which the ram is driven can be modulated using a pressure by-pass or by selection of the cartridges, or both. In order to reduce the risk of a fatal impact, the tip of the ram is provided with a blunt knob which can further include an inflatable cushion like member which is supplied with air or gas as the ram is displaced out of the barrel. The knob is removable allowing projectiles such as tranquilizer darts to be launched by loading the projectile into the hollow bolt and catapulting them towards a target or targets. Alternatively, the knob can be replaced with a chisel-like cutting tool and used as an emergency cutter in the event of a vehicle accident.

6. A device comprising:
-
a first elongate member having a hand grip portion; a second elongate member reciprocatively disposed in said first member in a manner to define a telescopic arrangement, said second member having an inboard end disposed in said first member and an outboard end, said second member being adapted to be driven by gas pressure in said first member so as to be displaced within said first member and to extend out of said first member by a predetermined distance, said second member being hollow and effective to interchangeably receive a projectile therein or have a third member rigidly connected to the outboard end; a spring disposed in said first member for biasing said second member toward a fully retracted position wherein the amount of projection of said second member out of said first member is minimized; and a source of gas under pressure which is responsive to a manually manipulatable member disposed on said hand grip portion, said source being fluidly communicated with said first member for supplying a gas under pressure thereinto and for producing the gas pressure which causes said elongate member to extend out of said first elongate member;
wherein said source comprises;a magazine operatively associated with said first elongate member, said magazine containing a plurality of gas generating cartridges; and a firing mechanism which is responsive to said second member assuming said fully retracted position to cause said plurality of gas generating cartridges to sequentially detonate and generate gas within said first member.

7. A device comprising:
-
a first elongate member having a hand grip portion; a second elongate member reciprocatively disposed in said first member in a manner to define a telescopic arrangement, said second member having an inboard end disposed in said first member and an outboard end, said second member being adapted to be driven by gas pressure in said first member so as to be displaced within said first member and to extend out of said first member by a predetermined distance, said second member having a hollow projectile receiving portion for receiving a projectile therein formed in said second member or having a third member rigidly connected to the outboard end; a spring disposed in said first member for biasing said second member toward a fully retracted position wherein the amount of projection of said second member out of said first member is minimized; and a source of gas under pressure which is responsive to a manually manipulatable member disposed on said hand grip portion, said source being fluidly communicated with said first member for supplying a gas under pressure thereinto and for producing the gas pressure which causes said elongate member to extend out of said first elongate member; wherein said third member includes an inflatable member, said inflatable member being fluidly communicated with a chamber defined between said first and second members, in a manner which permits air in said chamber to be displaced into said inflatable member when said second member is driven to extend out of said first member in response to the generation of gas in said first member.

8. A device comprising:
-
a first elongate member; a second elongate member reciprocatively disposed in said first member in a manner to define a telescopic arrangement; a source of gas under pressure operatively disposed in said first member which is responsive to a manually manipulatable member disposed on said first member and which selectively releases gas under pressure into said first member in a manner which drives said second member to slide in said first member and to project outward; and a knob disposed at an end of said second member which is effective for delivering a non-fatal disabling impact to a human body; wherein said knob is provided with an inflatable member, said inflatable member being supplied with a gas when said second member is driven to slide in said first member. - View Dependent Claims (9)
