Definitions

  • the closure is taken from its front position to its rear position by pushing the cocking slide backwards out of its rest position. When it snaps back from its rear position into its front position, the closure takes the cocking slide back to the front in its rest position, with a lock being provided to hold the cocking slide in its rest position.
  • Such a self-loading weapon corresponds to a known shooting submachine gun, in which the cocking slide is provided with a spring-loaded detent.
  • This detent spring engages behind the component of the housing that forms the front end stop of the cocking slide. "Shooting" means that the machine gun breech returns to its forward position after a shot has been fired.
  • This submachine gun has a cocking slide handle that is constantly protruding from the weapon housing and that during of the firing remains motionless, but can be quickly grabbed for loading.
  • a police operation is taken into account, according to which firearms should preferably not be carried through.
  • the aim of the invention is to prevent loading inhibitions in a self-loading weapon of the type mentioned at the outset.
  • the handle is pivotally mounted on the cocking slide and has a pawl which can be brought into positive engagement with a housing design for mounting the cocking slide and can be released from this engagement by pivoting the handle backwards when the cocking slide is pushed back (claim 1). It has been shown that the disturbances mentioned relate to the release of the catch on the cocking slide, which then runs against the mass of the closure and thus causes the interference.
  • the cocking slide is therefore no longer non-positively, but positively attached to the housing, and unlike certain rapid-fire guns, for example, no special handle is required to unlock the handle, for example.
  • the form-fitting fixing of the cocking slide on the housing almost completely eliminates the load inhibitions that are considered disadvantageous from the prior art.
  • this advantage is further developed in that the insertion and release of the positive lock does not require any separate or additional handling. While one grips the handle and pulls it back for loading, one also releases the form-fitting lock. If you let go of the handle in the rearmost position of the cocking slide and the lock, the mass of the laterally protruding handle at the front stop of the cocking slide engages the positive lock in the form of a pawl again.
  • Handle and pawl are preferably parts of an angle lever (claim 2).
  • the latch can be attached to all technically sensible points on the handle.
  • the angle lever carries a handle (or is designed as a handle) at the free end of its one leg, has the pawl at the free end of its other leg, and is mounted on the cocking slide in the region of its other ends that are adjacent to one another ( Claim 3).
  • the leg carrying the pawl thus extends in the longitudinal direction of the weapon or in the direction of movement of the breech and cocking slide.
  • the pawl is designed as a projection that points away from the handle. If the cocking slide strikes at the front end of its movement path, the mass force of the leg pushing forward, which carries or forms the cocking slide, swings the angle lever and thereby forcefully engages the pawl in the housing design.
  • the leg that carries the pawl and extends in the longitudinal direction of the weapon is significantly longer than the leg forming or having the handle. This increases the polar moment of inertia of the bell crank so that it cannot be easily pivoted due to the vibrations that occur in the weapon when it is fired. In addition, because of the long lever formed by the associated leg, only a very small holding force on the latch is sufficient to hold it reliably in engagement.
  • the pivot point of the angle lever and the center of gravity of the leg having the pawl are selected so that vibrations that occur when firing do not impair the locking of the angle lever.
  • the handle arranged on one leg of the angle lever advantageously consists of plastic. It has a low weight in order to contribute as little as possible to the mass forces which could affect the locking of the angle lever.
  • the entire cocking slide is preferably made of plastic (claim 6).
  • the housing design with which the handle or angle lever of the cocking slide engages can in principle be realized with any conveniently located housing part.
  • the closure which is driven forward by the closing spring, pushes the cocking slide against its end stop and thus causes the pawl on the handle to fall into the counter-formation on the housing.
  • a compression spring is attached to the cocking slide, which is supported on the handle so that its pawl snaps into place will (claim 8). Even in the case of vibrations, for example in the case of continuous fire, the handle cannot get out of the counter training.
  • This spring element is advantageously designed as a coil spring which is clamped in a receiving bore in the cocking slide.
  • the mounting hole extends coaxially to the direction of movement of the cocking slide.
  • the submachine gun shown has a housing 1 forming a guide.
  • a cocking slide 4 is slidably guided, which is pushed forward by a closure 2, which is attached further back and is shown only schematically in the drawing.
  • a closing spring 3 which is only symbolized by an arrow, acts on the closure 2.
  • the closing spring 3 pushes the closure 2 forward, that is to the left in the drawing.
  • the closure 2 pushes the cocking slide 4 in front of it until it strikes the facing end edge of a bush 5.
  • the sleeve 5 is welded into the guide.
  • an angle lever 6 is pivotally mounted about an axis 7.
  • the angle lever 6 has a first leg extending transversely to the longitudinal direction of the weapon, which protrudes from the housing 1 in the manner of a handle 10.
  • the handle 10 carries a handle 11 made of plastic.
  • the second leg 9 extends forward in the longitudinal direction of the weapon, is significantly longer than the first leg (handle 10) and ends in a hook-like pawl 9, which extends to the side of the angle lever 6 facing away from the handle 10.
  • the pawl 9 is arranged so that it grips behind the front end face 13 of the sleeve 5 and can hold the angle lever 6 and thus the cocking slide 4 in the front end position.
  • a bore is formed in a front end face of the tension slide 4 near the side wall of the housing 1, into which a compression spring 12 is pressed.
  • This compression spring 12 presses against the handle 10 and pivots it into such a position that the pawl 9 engages behind the end face 13.
  • the handle 11 When loading, the handle 11 is gripped by the shooter and pulled backwards (to the right in the drawing). First, the angle lever 6 is pivoted at least to the extent that the pawl 9 is released from the end face 13. Then the closure 2 is pushed back with the cocking slide 4.
