Definitions

  • the present invention relates to a magazine for insertion into a magazine receptacle of a firearm, which is converted for exercise or training purposes and which has a pneumatic device for simulating a recoil of the firearm when the trigger of the firearm is actuated, as well as the magazine.
  • the magazine has a pneumatic pressure accumulator in which a compressed gas is used to operate the pneumatic device of the Firearm is stored, and a filler opening, which is provided for filling the pneumatic pressure accumulator with pressurized gas from a pressurized gas source, with a check valve.
  • the check valve is designed to close the pressure accumulator gas-tight in its shut-off position if no compressed gas from the pressure gas source is present at the filling opening, in order to prevent the pressure gas stored in the pressure accumulator from escaping.
  • the invention also relates to a firearm that is converted for exercise or training purposes and which has a pneumatic device for simulating a recoil of the firearm when the trigger of the firearm is actuated and a converted magazine with a pneumatic pressure accumulator in which a compressed gas for actuating the pneumatic Device of the firearm is stored.
  • weapon simulators which simulate the firing of weapons. Firearms are used that have been converted for training purposes.
  • the weapon simulators are mainly used in the military environment.
  • U.S. 4,302,190 discloses a recoil simulator for a rifle in which compressed air is passed through openings in the gun barrel to move the gun barrel upward in a simulated recoil motion.
  • a switch on the trigger activates an electromagnetic pneumatic valve to control the flow of air to the openings in the gun barrel.
  • the recoil is not simulated by a slide that can be moved to and fro, but rather solely by a controlled air flow.
  • a modified firearm for a weapon simulator in which a reciprocating shutter is pneumatically triggered by means of compressed air when the trigger is actuated.
  • the known firearm has a pneumatic pressure accumulator included, from which air can escape via electromagnetically operated pneumatic valves when the trigger is actuated and can be used to move the shutter back and forth.
  • Handguns modified for training purposes are known in which the pneumatic pressure accumulator, in which compressed gas is stored for actuating the device for simulating recoil of the weapon in the event of a shot being fired, is part of a modified magazine.
  • the converted magazine is very similar to a real magazine, which contains cartridges to be fired by a real firearm. Just as a real magazine can be inserted into a magazine receptacle in the handle section of a real firearm, the converted magazine can be inserted into a magazine receptacle in the handle section of a converted firearm and detachably fastened therein.
  • the pressure accumulator contains a certain amount of compressed gas so that a certain number of shots can be fired with the converted firearm. With each shot fired, part of the compressed gas stored in the pressure accumulator is released into the device for simulating a recoil. When the maximum possible number of shots has been reached, the pressure accumulator must be recharged, which can be done with a suitably designed charging device.
  • the converted magazine with the pneumatic pressure accumulator has an outlet opening through which the into the
  • Magazine receptacle in the grip portion of the converted firearm inserted magazine or the pneumatic pressure accumulator contained therein is connected to the device for simulating a recoil of the firearm.
  • a check valve is assigned to the outlet opening of the converted magazine, which automatically closes the outlet opening as soon as the magazine is removed from the magazine receptacle and releases the outlet opening as soon as the magazine is completely inserted into the magazine receptacle.
  • the converted magazine has a filling opening through which the pneumatic pressure accumulator can be filled with compressed gas.
  • the filling opening of the converted magazine is assigned a check valve which automatically closes the filling opening as soon as the magazine is no longer connected to a compressed gas connection of a compressed gas source or no more compressed gas is flowing to charge the pressure accumulator, and the filling opening is released as soon as the magazine is connected to a compressed gas connection Pressurized gas source is connected and pressurized gas flows to charge the pressure accumulator.
  • the check valves of the known converted magazines are usually constructed in a conventional manner, that is, they have a valve body, for example in the form of a ball, which is pressed against a valve seat by means of a spring element.
  • Check valves designed in this way are, however, only for relatively low ones Suitable pressures are, for example, about 11 bar when using butane as the compressed gas or about 57 bar when using carbon dioxide as the compressed gas.
  • Suitable pressures are, for example, about 11 bar when using butane as the compressed gas or about 57 bar when using carbon dioxide as the compressed gas.
  • the magazine does not form a flat surface in the area of the filling opening and the check valve. Rather, the filling opening is always clearly visible, so that when the firearm provided with the known magazine is used, dirt and moisture can deposit in the filling opening, which then impairs the filling of the pneumatic pressure accumulator of the magazine with compressed gas, since a gas-tight connection between a Pressurized gas source of a loading device and the pressure accumulator of the magazine can then possibly no longer be produced.
  • the magazine can only be opened safely for maintenance or repair purposes if there is no longer any compressed gas under pressure in the pressure accumulator. Otherwise the accumulator may explode when it is opened.
  • the DE 10 2015 211 619 A1 describes a converted magazine of a hydraulic device for simulating a recoil of a firearm with a check valve designed as a ball, which can be filled with compressed air up to 300 bar.
  • the US 2012/0006445 A1 describes a connection device for a pressure vessel which, on the one hand, has a conventional check valve for pressure-tight closing of the pressure vessel and, on the other hand, has an additional dust prevention valve.
  • the present invention is therefore based on the object of designing and developing the known magazine in such a way that it can be filled with compressed gas at very high pressures in the range of about 250 to 300 bar via the filling opening so that the filling opening is protected against contamination and damage from the outside and that, if possible, it can also be recognized directly and clearly from the outside without additional aids whether the pressure accumulator of the magazine is depressurized or not.
  • a magazine with the features of claim 1 is proposed.
  • a converted magazine of the type mentioned is proposed, the non-return valve of which has a valve piston which can be moved in a valve bore parallel to the direction of flow of the compressed gas through the filling opening, which forms the closure part of the non-return valve and at its distal end a valve piston to the outside of the Magazine-directed outer surface and is designed such that the outer surface of the valve piston in the shut-off position of the check valve is flush with the outside of the magazine.
  • the valve piston forms the closing part of the check valve. It is deliberately designed as a piston with an outer surface facing the outside of the magazine at a distal end of the piston. In the shut-off position of the check valve, this outer surface of the valve piston closes flush with the outside of the magazine around the filling opening, so that a flat outside of the magazine also results in the area of the filling opening. Penetration of dirt and / or moisture into the filling opening is effectively prevented.
  • a gas-tight connection between a pressurized gas source of a loading device for filling the pneumatic pressure accumulator of the magazine with pressurized gas and the pressure accumulator of the magazine can be established with greater safety and reliability.
  • an outlet opening of the loading device can be connected in a gas-tight manner to the filling opening of the magazine or of the pressure accumulator without problems due to contamination or moisture, in order to fill the pressure accumulator with compressed gas.
  • the design of the closure part of the check valve as a valve piston results in a significantly more stable and robust design of the check valve, so that it is also very problem-free Can withstand high pressures in the range from 250 to 300 bar, such as occur, for example, when using compressed or compressed air when filling the pressure accumulator with compressed gas and in the pressure accumulator itself.
  • the outer surface formed on the distal end of the valve piston serve to indicate whether or not compressed gas is still present under pressure in the pneumatic pressure accumulator of the magazine. This applies in particular when only the pressure of the compressed gas applied from the outside on the valve piston is released from the Pressurized gas source and the pressure of the pressurized gas stored in the pressure accumulator on the inside of the valve piston cause the valve piston to move parallel to the direction of flow of the pressurized gas through the filling opening and the check valve has no additional spring elements. In this case, the outer surface of the valve piston is flush with the outer surface of the magazine as long as the pneumatic pressure accumulator is under pressure.
  • valve piston Only when the pressure accumulator is depressurized does the force no longer act on the valve piston, which could push it outwards into the shut-off position, and the valve piston falls into a retracted rest position in which the outer surface of the valve piston is immersed in the filling. This can be easily seen from outside the magazine without additional tools.
  • the valve piston can move into the rest position either due to gravity or supported by an additional spring element as soon as the pressure in the pressure accumulator has fallen below a certain low pressure value. As a result, the safety when handling the magazine, in particular with regard to maintenance and repair, can be significantly improved.
  • a firearm converted for training purposes as part of a weapon simulator is designated in its entirety by the reference symbol 1.
  • the weapon simulator (not shown) is used to train operations that are as realistic as possible using converted firearms, such as the firearm 1.
  • the weapon simulator can have a central control computer include, in which all firearms used in the vicinity of the weapon simulator, for example the firearm 1 and other retrofitted firearms, are registered or registered.
  • the control computer is in a communication connection with the registered firearms, which can be implemented via an electrical line or wirelessly, for example via radio.
  • the control computer is used to coordinate and evaluate training units for the individual registered firearms.
  • a central control computer of the weapon simulator can also be dispensed with if, for example, the converted firearm 1 is used for recreational purposes.
  • the firearm 1 resembles a real firearm in terms of its appearance and weight, as well as its haptics and operability.
  • the firearm 1, however, has been converted so that it does not fire any blank cartridges or real ammunition.
  • the various actions which take place in a real firearm before, during and after a shot is fired and which cause the weapon to recoil must therefore be simulated in the converted firearm 1.
  • the firearm 1 has a device pneumatically operated by means of compressed gas for simulating a recoil when "firing" a simulated shot.

  • the movement of the closure 3 can be triggered, for example, by means of a shooting cylinder / piston arrangement 9.
  • a further sensor (not shown) can be provided to detect the movement of the closure 3.

  • the trigger 2 is actuated, the breech 3 is pushed back and forth by pressurized gas from the pressure accumulator 13 moved here. It is conceivable that only the backward movement of the closure 3 is generated by the pressurized gas, whereas the forward movement is generated in another way, e.g. by a return element (e.g. a compression spring) acting on the closure 3, as soon as there is no more pressurized gas the closure 3 rests.
