Definitions

the invention relates to a trigger device for automatic handguns with a catch lever, which holds the breech which retracts after firing against spring force when the trigger is released on a nose in the rear position.
Handguns of this type have the advantage that each time a shot sequence is interrupted the cartridge chamber of the barrel remains empty, so there is no cartridge in it and therefore there is no risk that the cartridge may self-ignite after the barrel has overheated due to overheating of the barrel.
the catch lever is subject to a very high load because it suddenly has to stop the forward closure with its high kinetic energy.
the catch lever and the other associated parts of the trigger device or the breech guide are made of high-strength materials, in particular hardened steel, which not only increases the weight of the weapon, but also increases the technical outlay in the production of these parts.
the invention is therefore based on the object to remedy this deficiency and to improve the trigger device described at the outset with simple means such that, despite the deformations which may occur, there is no reduction in the overlap of the catch lever and locking lug, that is to say there is full security and a favorable force distribution is achieved is so that the catch elements can even be made of plastic.
the catch lever carries at its front end a catch pawl cooperating with the nose on the closure, which is designed as a double-armed pivot lever, the front lever arm of which is supported against the force of the closure spring on a sprung abutment, between the rear lever arm this pivot lever and the catch lever a spreading compression spring is used.
the catch catch pivots through the spring-loaded abutment in the direction of action of the locking spring and thus in the sense of an increase in the overlap of the nose on the lock, so that the necessary overlap is retained despite any elastic deformation of the locking lever and the risk of unwanted Gunshot is avoided.
the spring-loaded abutment acts as a kind of shock absorber for stopping the lock.
the compression spring used between the pivot lever forming the catch lever and the catch lever serves in operative connection with the resilient support on the abutment as a return spring in order to return the catch lever to its starting position after the firing of the shot, in which it or the like from a slide connected to the trigger. is held.
the drawing shows an embodiment of the parts of a trigger device for an automatic rifle essential to the invention in partial section and simplified representation.
the trigger device has a housing 1 in which a slide 2, which is coupled via a trigger rod 3 to the trigger that can be actuated by the shooter's finger, is mounted so that it can be pushed back and forth. Furthermore, a catch lever 4 is arranged in the housing 1 so as to be pivotable about the axis 5 and carries a catch pawl 6 at its front end.
the catch pawl 6 is designed as a double-armed pivot lever, the front arm 7 of which is supported on a sprung abutment 8.
a spreading compression spring 10 is inserted between the rear lever arm 9 of the catch link 6 and the catch lever 4. With 11 longitudinal guides for the closure 12 are referred to, which is loaded by a strong locking spring 13 and carries on its underside a cooperating with the catch 6 nose 14.
the breech 12 is held against the force of the breech spring 13 by the catch pawl 6, there being no cartridge in the cartridge chamber (not shown).
the catch lever 4 is prevented from pivoting by the web 15 of the slide 2 which engages over it. If the trigger is actuated, that is to say the slide 2 is moved backwards via the trigger rod 3, the rear end of the catch lever 4 is released and can pivot upwards under the pressure of the locking spring acting on the catch pawl 6 via the nose 14, so that the lock 12 flaps forward, take a cartridge from the magazine (also not shown) and insert it into the cartridge chamber, after which the shot is fired in the usual way and the breech 12 is moved back against the force of the breech spring 13.
