The invention relates to a locking device for automatic and semi-automatic Firearms with a cocking handle that can be engaged and disengaged with the breech for cocking connected to the weapon.

The purpose of the invention is to provide a shutter tensioning device of relatively simple construction to create the greatest possible security in the event of failure of the weapon against the known Executions guaranteed.

It is already known in the case of the types of weapon mentioned at the outset, the locking handle in the front Locking position during automatic firing to avoid possible dangers to prevent hand injuries with the known forced movement of the cocking handle. to For this purpose, the locking handle with the cocking slide by means of a tension or compression spring held in the forward position. A disadvantage here turned out to be that no possibility more was given, together with the locking parts by means of the cocking handle in the event of a jam etc. to carry out inevitable axial shaking movements, since in this arrangement the The cocking handle could practically only move the lock back.

Furthermore, devices on so-called self-loaders for manual retraction of the locking chamber are known, in which the handleless chamber has a prismatic cutout on its front part, in which engages the bottom of a cartridge or a similarly shaped tool as a clamping handle and is removable for the purpose of initial loading or, if the weapon malfunctions, it is withdrawn the locking chamber guaranteed.

This approach was also viewed as a temporary solution in practice and could be used in the long term not satisfy. In order to avoid all the disadvantages indicated, the cocking handle is according to the invention arranged on a cocking slide, which sits in front of the closed shutter and the shutter only takes with it in the opening direction, at times, depending on requirements, additionally by pressing down, Rotation or pivoting of the cocking handle in any locking position a locking member in a Lock recess recess engages on the front side of the lock and a forced shaking movement in the axial direction and allows the lock to be taken into the front starting position.

• Due to this particularly simple design, it is now possible to use the fastener tensioning button with a fastener for automatic
and semi-automatic firearms

to couple the lock optionally in any locking position, in particular when the closure during use of the weapon as a result of external influences, for example Dirt penetration between the sliding surfaces of the lock, load jamming or other disturbances, stuck in an intermediate position. By engaging the clutch and forced shaking movement with the lock there is the possibility of taking the lock into the front To make the position normal again and thus ready for use.

In the drawing, several forms of construction of the invention, which are used as exemplary embodiments, are dung object shown, namely shows

F i g. 1 shows a partial cross-section in the longitudinal direction of the firearm with the locking parts and uncoupled Locking handle,

F i g. 2 shows a cross-section in the longitudinal direction of the locking handle of a second embodiment,

F i g. 3 shows a view from below in the direction of arrow A in FIG. 2,

F i g. 4 shows a cross section in the longitudinal direction of the latch tension handle of a third embodiment, F i g. 5 shows a partial cross-section of the locking parts with the locking lever which can be folded in the longitudinal direction as a fourth embodiment,

F i g. 6 shows a section in the transverse direction of the closure parts with a laterally foldable clamping lever as fifth embodiment.

According to FIG. 1, the locking member 2 is firmly connected to the cocking handle 3, the latter being axially held and guided by the inner bore through the bushing 4. A compression spring 5 holds the cocking handle 3 and the locking member 2, which slides simultaneously in the cocking slide 6, firmly in the normal upper disengaged position and is pulled forward and held under the influence of the tension spring 7 in the direction of the arrow up to the stop 8. The front part of the lock 9 has a lock trough recess 10 into which, as required, by finger pressure

actuation on the cocking handle 3 engages the locking member 2 and establishes the coupling connection with the lock 9 . The guide housing 11 serves to guide the lock 9 in the longitudinal direction, the rear bearing 12 and the gun barrel 13 as well as the cover slide 14 representing further functional parts of the locking device.

The functional sequence is as follows: stepping due to contamination of the locking parts by powder residues, external effects of dirt, ζ. Β. ίο by dropping the weapon in the area, or otherwise Effects of foreign bodies Faults caused by jamming or sticking of the locking part guides which cause the weapon to fail, the cocking handle 3 is opened by finger pressure moved downward in the axial direction. At the same time, the locking member 2 is taken along, enters the path of movement of the shutter recess 10 and thus establishes the connection with the shutter 9 ago. Due to the forced vibration ao movement in the axial direction, the entrainment is in the front starting position guaranteed without the usually necessary and with these types of weapons to have to perform time-consuming dismantling.

Figures 2 and 3 illustrate the same embodiment according to FIG. 1, only here the additional possibility is given by pressure and Turning the cocking handle 3 with simultaneous automatic rotation of the locking member 16 in the latter to lock the coupled position.

Appropriately, a nose 17 is attached to the lower part of the locking member 16, which into the corresponding recess 18 of the cocking slide 6 engages and the coupling connection with the lock 9 accomplished. The uncoupling takes place after a short push downwards and at the same time Rotation in the direction of the arrow according to FIG. 3 in the opposite direction with removal of the nose 17 from the recess 18 of the cocking slide 6 and the simultaneous return movement of the locking member 16 from the locking trough recess 10 into the starting position, the cocking slide 6 by means of the Tension spring 7 is automatically returned to the stop 8 with.

According to FIG. 4, the coupling connection takes place by turning the clamping handle 3 accordingly steeply arranged threads 19 with the same purpose, the coupling connection to do this with the shutter 9. Here, however, the locking handle 3 must go to uncoupling be turned back again to when closing in the front position at the stop 8 in the disengaged Position to lie, which also takes place automatically under the influence of the tension spring 7.

Another embodiment is shown in FIG. and that is hereafter as a coupling connection part with the lock 9 in the longitudinal direction of the weapon reversible clamping lever 20 is arranged, which has a locking member 21 in the form of a cam part, which after turning the clamping lever into the dashed position 20 'in the path of the locking recess recess 10 moves and in this way establishes the coupling connection. The latter clamping lever 20 is mounted on a bolt 22 which a clock spring 23 is attached, which with their Legs 24 and 25 lies behind the stops 26 and 27 and the clamping lever 20 is under spring pressure automatically moved back from position 20 'after releasing it into the disengaged rest position.

Finally, according to FIG. 6 shows a further embodiment, similar to that of FIG 5, only here the clamping lever 20 is arranged in the transverse direction of the weapon by means of the bolt 28. A curve part 29 of the tensioning lever 20 lies on the surface 30 in the disengaged position a standing under the action of a compression spring 31 locking member 32, which after pivoting the Tension lever 20 in the position 20 'shown in dashed lines through the cam 33 in the path of the locking recess recess 10 is moved and thus causes the coupling connection. The curve part 33, for example, can be designed so that the The clamping lever 20 can automatically pivot back into its rest position in order to close the coupling connection to solve.
