Abstract:
A laser pistol for simulating pistol shots by retrofitting a pistol, comprising:a pistol grip (30); a barrel (9) mounted on the pistol grip (30); a slide (29), which is supported by the pistol grip (30) and is movable along the barrel (9); a trigger (31) with a trigger guard (32), which are attached to the pistol grip (30) and the barrel (9); a striking pin mounted in the slide including means for cocking the striking pin (35) and actuating the pistol; and a compressed-gas magazine (16), which is insertable from below into the pistol grip (30) and on its upper end has a connection valve (14) and on its lower end is provided with a connection bore (18), in which a check valve (17) is seated; a laser module (1) positioned in the barrel (9), which upon actuation of the trigger (31) emits a target-spot laser beam; an electronic control disposed in the pistol and coupled with the laser (1) and the trigger (31); a battery in the pistol grip (30) or barrel (9) which is connected to the electronic control; a compressed-gas cylinder (20) disposed in the slide (29) which is attached to a switchover valve (2) having a valve tappet (4) arranged such that upon actuation of the trigger (31), compressed gas from the compressed-gas cylinder (20), moves a piston (6) rearward via through the switchover valve (2) via the valve tappet (4); a compressed-gas chamber (3) positioned in the slide such that the compressed-gas cylinder (20) communicates fluidically with the compressed-gas chamber (3) via the switchover valve (2), the compressed-gas magazine (16) is adapted in its dimensions to the magazine of a pistol that is to be retrofitted, and being attached to a magazine connection piece (10), the connection valve (14) being connected to the magazine connection piece (10) which has a through bore (34) having an opening pin (13) for the connection valve (14) and a connection (12) with the compressed-gas magazine (16) and a hose coupling (11) to an expansion chamber (7) in the slide (29) above the a barrel block (8); and that the piston (6) is positioned in the expansion chamber (7) and is disposed in a bore extending in the longitudinal axis of the barrel (9) and in juxtaposition with a firing pin piece (5) in the bore which is movable in the bore back and forth, which piston is disposed upstream of the tappet (4) of the valve (2), and between the valve (2) and the firing pin piece (5), and the inner wall of the piston is provided with a slight slip or play for ventilating the expansion chamber (7); the striking pin (35) being positioned to impact the firing pin piece (5); and that a spring rod (21) and a return spring (36) are positioned under the barrel and adapted to the existing pressure conditions, in order to press the piston (6) and the firing pin piece (5) back via the slide (29).
