Definitions

  • the invention relates to a safety device for rifles with a trigger, which acts via a trigger rod on the rearward offset trigger mechanism and can be blocked by an arbitrarily actuable fuse.
  • the assembly formed by the trigger and the trigger rod which can also be connected to a rigid structural unit, receives a relatively large mass. If the trigger that blocks the trigger is released when the trigger is cocked, i.e. the rifle is ready to fire, an unwanted bounce in the longitudinal direction of the rifle can result in an unwanted firing of the shot because the inertia forces of the assembly formed by the trigger and trigger rod are sufficient to actuate the rest of the trigger device . Such an unwanted shot, caused by a blow to the piston or the barrel muzzle, naturally represents a special risk of an accident.
  • the object of the invention is to remedy this deficiency and to improve the securing device described at the outset in such a way that an undesired firing by shocks in the longitudinal direction of the rifle when the rifle is fired and the rifle is unlocked is avoided.
  • the invention achieves the stated object in that an additional safety device is provided which can be pivoted about an axis transverse to the longitudinal direction of the rifle by means of a flywheel and is held in the central position by spring force and which forms a stop preventing the trigger movement outside its central position.
  • the additional safety device is pivoted in one direction or the other by the swing weight and therefore comes out of its central position, so that it then moves the trigger caused by mass forces, which would lead to the unwanted firing of the shot, prevented. If the shock load is over, the additional safety device returns under the spring action to its central position, in which the trigger has free movement, so that the intended firing of the shot is then unobstructed.
  • the additional safety device consists of an angle lever which carries the swing weight on one arm and the other arm directed against the trigger has two locking lugs or the like which have a space for the passage of a trigger approach. in the middle position of the additional security.
  • the angle lever is pivoted in one direction or the other, and one or the other locking lug comes into effect, whereas the trigger in the middle position of the angle lever has free passage between the two locking lugs and thus the arbitrary trigger movement remains unhindered.
  • the arm directed against the trigger of the angle lever forming the additional safety device is fork-shaped and the trigger between the fork blades directed so that there is a particularly simple and reliable construction.
  • An automatic rifle 1 has a trigger 2, which consists of the trigger rod 3 in one piece and is only displaceably mounted in the longitudinal direction of the rifle.
  • the trigger rod 3 acts on a catch lever 4 which holds the striker 5 in its tensioned position.
  • the spring acting on the striker 5 and the return spring for the trigger 2 are not shown for the sake of clarity. 1 and 2 is in the position corresponding to the cocked striker 5. In this clamping position, the trigger 2 can be blocked by an arbitrarily actuable fuse 6, which can be moved normally to the image plane, lies in front of a nose 7 of the trigger 2 or releases it for unlocking.
  • an additional safety device which consists of an angle lever 10 which can be pivoted about an axis 8 running transversely to the longitudinal direction and is held in the central position by two springs 9.
  • the downward arm 11 of the bell crank 10 carries a swing weight 12, whereas the other arm directed against the trigger 2 is fork-shaped and thereby has two locking lugs 13, which leave a space 14 for the passage of a trigger extension 15.
  • the angle lever 10 pivots through the swing weight 12 against the force of one of the springs 9 in one direction or the other and one or the other locking lug 13 comes into effect because it is behind the trigger attachment 15 and thus prevents a trigger shift in the direction of the arrow.
  • the trigger 2 can be actuated without further ado because its extension 15 finds clearance in the intermediate space 14 between the locking lugs or fork blades 13.
