Definitions

  • the invention relates to a safety mechanism for a catch lever of a
  • Fully automatic rapid firearms usually work in such a way that, when the weapon is tightened, the closure is brought against the spring force of one or more closing springs into a rear catching position and arrested. The clamping is normally done manually. By actuating the trigger this lock is released and the closure is brought by the spring force of the closing spring (s) in the closure career forward. By this closing movement, a cartridge is inserted into this closure career, locked in the chamber at the front end of the closure career and ignited there. After unlocking the shutter this is brought by the gas pressure and the recoil to the rear in its catching position and ejected the empty cartridge case. The feeding mechanism of the cartridge is then realized either by a positive control by the moving shutter or by the gas pressure when igniting the ammunition.
  • Unintentional firing of a weapon when it is released by releasing the catch is often prevented by a lock which mechanically locks the trigger or directly holds the catch in its catching position.
  • Rapid firearms such as submachine guns or machine guns, which are equipped to deliver sustained fire, have a fairly simple trigger mechanism, of which a representative example will now be described with reference to FIGS. 3 and 4

  • This rear, upper part of the trigger acts on the front end of a catch lever (f), which in turn is pivotable about a transverse axis in the Kumargehause or Griffstuck the rear end of the catch lever (f) is as a sear (s) formed when the trigger (a) is pivoted by a spring to its rest position forward, then pivot the front end of the catch lever (f) - also under spring action - down, and its rear end with the sear (s) to the top
  • This position of the sear is the locking position (see Fig. 3)
  • trigger (a) and catch lever (T) can each be cushioned or biased by its own or a common spring and are of this pressed into their rest position (trigger) or their locking position (catch
  • the sear (s) When the trigger (a) is activated, the sear (s) lowers until it clears the lug, the lock is released and the gun starts firing. If the trigger (a) is released, then the sear (s) jumps back up into its locking position, behind the latching lugs and holds the shutter in its fire-ready position (rear position). The sustained fire breaks off.
  • a pure trigger guard is often used, although precludes the unintentional actuation of the trigger, but not a yielding of the Abzugsss Hecks due to acceleration forces, for example, when the loaded, tensioned and deducted machine gun falls from a truck
  • Lock with secured weapon can not be withdrawn over the locked catch (f) or can jam on the catch (f), because the latter can not escape.
  • a backup roller (w) which assumes with its peripheral surface a securing finger (i) of the catch lever (f), Fig. 3. A weapon with such a fuse (w) can not be loaded in the secured state.
  • the further malfunction may occur here that the weapon fires uncontrollably even with interrupted trigger action.
  • High actuating forces of the actuator for the safety device may cause the safety device (i) in the safety catch (f) to jam in such a way that the sear (s) remains out of engagement with the detent lug on the closure.
  • This malfunction may occur when the shutter is back on its way forward immediately after the trigger operation, and a power failure causes the trigger to be released at the same time and the actuator acting on the fuse will return it to its "safe" position.
  • Safety finger (i) dips into the safety recess on the safety device (here: the safety roller (w)). Now, if the actuator, the backup roller (w) in the direction of "safe” blocks the locking finger (i) their travel and the edge of the securing recess is u.U. pressed so firmly against the safety finger (i) that the catch lever (f) despite spring action can not move into its locking position.

  • the catch lever (f) is jammed over the locking finger (i) and the shutter moves freely firing back and forth until the ammunition supply is interrupted (see Fig. 4).
  • a securing element is provided, which cooperates with the securing device (for example, a backup roller) so that it is always - regardless of the position of the closure or the catch lever - can be brought into their secure position.
  • the safety device can act both on the trigger and on the catch lever.
  • an additional spring element is required to ensure the locking function, and the sling and its pivoting suspension must receive the full force of the leading closure.
  • the relatively small catch and its suspension are exposed to high dynamic loads. A possible breakage or failure of the sling, its suspension in the catch lever and / or the spring element in the worst case so on the weapon function that fires regardless of the position of the fuse and the trigger until the entire ammunition is fired ,

  • the securing mechanism specified there acts on the securing means engaging its securing position and fixes the catch lever in a locking position.
  • a spring element acting between the securing device and the catch lever exerts a locking force which determines the catching lever in its locking position.
  • the locking force exceeds a withdrawal force that brings the catching lever out of a locking position, so that the withdrawal force is insufficient to bring the catching lever out of its locking position and to trigger a shot.
  • the locking force is adjusted so that the catch lever under the action of the returning shutter allows deformation of the spring element (against the locking force) and to such an extent that the catch lever can reliably catch the closure.

Abstract

La présente invention concerne un mécanisme de sûreté (20) pour un arrêtoir de culasse (2) d'un dispositif de détente d'une arme à feu, notamment d'une arme à tir rapide, présentant une culasse et un dispositif de sûreté (6, 8, 8a). L'arrêtoir de culasse (2) peut être déplacé entre une position d'arrêt arrêtant la culasse et une position n'arrêtant pas la culasse. Le mécanisme de sûreté (20) s'engage sur le dispositif de sûreté (6, 8, 8a), lorsque ce dernier passe en position de sûreté, immobilisant ainsi l'arrêtoir de culasse (2) en position d'arrêt. Le mécanisme de sûreté (20) présente un élément ressort (23c) agissant entre le dispositif de sûreté (6, 8, 8a) et l'arrêtoir de culasse (2), ledit élément ressort exerçant une force d'arrêt immobilisant l'arrêtoir de culasse (2) en position d'arrêt, laquelle force est ajustée de façon à être supérieure à une force de détente, dégagant l'arrêtoir de culasse (2) de sa position d'arrêt, et à permettre une déviation de l'arrêtoir de culasse (2) sous l'effet du recul de la culasse et sous la déformation de l'élément ressort. L'invention concerne également un dispositif de détente, une carcasse (1) et une arme munie d'un tel mécanisme de sûreté (20).
