is a schematic cross-sectional view of the barrel in a detail showing the details of the invention.

The laser gun according to the invention is shown in FIGS. 1a and 1b in a schematic representation with a handle 30 shown that in a manner known per se with a run 9 Trestle 8 carries, which are covered by a carriage 29. A trigger 31 is pivotable in the body of the laser gun stored and is protected by a trigger guard 32.

A pressurized gas magazine 16 according to the invention is defined in claim 2 shown. The latter is in the handle 30 from below inserted and has the dimensions of the original magazine (Not shown). In the barrel 9 of the laser gun according to the invention is a laser module 1 with acceleration switch and Batteries (not shown) inserted. Other arrangements of the However, the laser module is in front of or next to the spring rod 21 conceivable. A rear sight is at the rear end of the slide 29 arranged on the slide 29 in a manner known per se, while on the front end of the sled 29 one by itself known grain is intended for aiming.

The compressed gas magazine 16 has a connection valve at its upper end 14 and a connection hole at its lower end 18 on, in which a check valve 17 is seated. To the Check valve 17 may possibly not shown Hose line can be connected to the pressurized gas magazine 16 with compressed air, nitrogen or under pressure Carbon dioxide continuously supplied. In the latter The case is of course the size of the compressed air magazine 16 no longer dependent.

In the ideal case, the compressed gas magazine 16 closes with the lower one Edge of the handle 30, so that the outer contour of the Original Glock® pistol is retained. A minor one Enlargement of the compressed gas magazine 16 and the extension the handle 30 is also intended by the invention be included.

In Fig. 3, the magazine connector or intermediate piece 10 in shown its structure, which via its connection 12 with the connection valve 14 is connected and at its upper end a hose connection 11 with an expansion chamber 7 in the carriage 29 above the running block 8. In the Bore 34 is an opening pin 13 for the connection valve 14 arranged.

In Fig. 4 the converted barrel 9 is described with trestle 8, which in turn with respect to its dimensions Barrel and trestle of the respective model to be converted previously known sniper pistol is adapted. It appears So that the replacement system according to the invention practical consists only of the three compact parts to be converted, which are shown in Figures 2 to 4, being the fourth Part of the spring rod 21 with return spring 36 to the prevailing Pressure ratios are adjusted to over the Carriage 29 the piston 6 and the striker 15 back to press. To reduce the setback have conventional Sharp guns a barrel lock. The spring force its return spring is approximately 55 N. This return spring is exchanged for a return spring 36 with approx. 25 N, to use the existing compressed gas economically, whereby on the barrel lock is advantageously dispensed with and Counterpart on the carriage is removed. The conversion of Original sharp pistols of any kind can therefore in Principle can be done easily and quickly and is also extremely inexpensive, apart from the fact that the dismantling itself behaves equally.

From the process flow, the compressed gas magazine 16 is in the Handle 30 of the gun inserted, causing itself on the opening pin 13 the magazine connection valve 14 in the magazine connection piece 10 opens. As a result, the compressed gas flows, in particular Compressed air, through the magazine connector 10 in the Running block 8 from where it is through the flow opening X reaches the pressure chamber 3 behind the changeover valve 2. With the striking of the firing pin 35 of the invention Laser gun will hit 5 on the valve lifter 4 driven, which opened the same against the spring pressure (see also Fig. 5). This flows under Pressure gas from the pressure chamber 3 through the open Changeover valve 2 in the expansion chamber located in the cylinder housing 20 7. This makes the piston 6 powerful flung the striker 5 back. During this process becomes constant over the slip or the tolerance between the striker 5 and the piston 6 and through the bore 22 for the striker 5, the expansion chamber 7 is vented and the changeover valve 2 closes by means of pressure Spring 19. In the present case there was a slip or play 15 selected from about 0.1 mm, but larger or smaller Values are conceivable from case to case. The high initial pressure still moves the piston 6 and slide 29 rear. At the end point of the piston stroke is due to the volume increase and venting the pressure again is sufficient reduced. As a result, the carriage 29 presses by means of the spring pressure the return spring 36 the piston 6 and the striker 5 forward. During this process will continue constantly vented via the striker 5 and the piston 6, for rapid volume reduction in the expansion chamber 7 to achieve. This ensures that the carriage 29 forward with realistic speed fast. The speed of this movement is necessary so that the shooter has a realistic overall impression of Setback. During the movement of the slide 29 the firing pin 35 and the trigger mechanism of the gun curious; excited. Depending on the gun model, the hammer (not shown) excited. This is not the case with the Glock® pistol the case. Simultaneously with the striking of the firing pin 35 is with an acceleration switch integrated in the laser module 1 a brief laser pulse is triggered. This Laser pulse can be taken from existing interactive shooting systems be evaluated.
