Abstract

The invention relates to a drop-safety mechanism for a firearm having a pivot-mounted, trigger, said trigger being designed as an arm of a double lever, the other arm of which supports a counterweight that can be displaced between a rest position and a functional position. The counterweight is resiliently pre-tensioned in the rest position and strikes on a part of the firearm in the functional position to block the trigger from unintended firing.

Claims (9)

1. Drop-safety mechanism for a firearm with a pivot-mounted trigger, wherein the trigger is constructed as one arm of a two-armed lever with respect to the pivot, a counterweight movably mounted directly to the other arm of the lever the counterweight being movable between a rest position and a functional position, the counterweight being spring-biased toward the shooting direction of the firearm in the rest position and moves overcoming the bias of the spring to strike against a part of the firearm in the functional position to block movement of the trigger and prevent unintended firing.

2. Drop-safety mechanism according to claim 1 , wherein the counterweight is pivot-mounted on the other arm of the lever, and wherein the counterweight is spring-biased via a compression spring which acts between a shoulder of the counterweight and a shoulder of the other arm.

3. Drop-safety mechanism according to claim 1 , wherein the part of the firearm against which the counterweight strikes in the functional position is a part of a hand-cocking mechanism of the firearm, the hand cocking mechanism being movable between a cocked and an uncocked safety position.

4. Drop-safety mechanism according to claim 2 , wherein the part of the firearm against which the counterweight strikes in the functional position is a part of the hand-cocking mechanism of the firearm, the hand cocking mechanism being movable between a cocked and an uncocked safety position.

5. Drop safety mechanism according to claim 3 , wherein the hand-cocking mechanism comprises an actuator element which acts via a linkage on a catch to move the catch between a cocked and an uncocked safety position and the part which the counterweight strikes is the linkage.

6. Drop safety mechanism according to claim 4 , wherein the hand-cocking mechanism comprises an actuator element which acts via a linkage on a catch to move the catch between a cocked and an uncocked safety position and the part which the counterweight strikes is the linkage.

7. Drop-safety mechanism for a firearm with a pivot-mounted trigger wherein the trigger comprises a first arm of a two-armed lever with respect to the pivot, a second arm of the lever supporting a pivot-mounted counterweight, the counterweight being movable between a rest position and a functional position, the counterweight being pretensioned into the rest position and moves to strike against a part of the firearm in the functional position to block movement of the trigger and prevent unintended firing, and wherein a compression spring acts between a shoulder of the counterweight and a shoulder of the second arm.

8. Drop-safety mechanism according to claim 7 , wherein the part of the firearm against which the counterweight strikes in the functional position is a portion of a hand-cocking mechanism of the firearm, the hand cocking mechanism being movable between a cocked position and an uncocked safety position.

9. Drop safety mechanism according to claim 8 , wherein the hand-cocking mechanism comprises an actuator which acts via a linkage on a catch to move the catch between a cocked and an uncocked safety position and the part which the counterweight strikes is the linkage.
