Abstract

Trigger assemblies for firearms, such as pistols, that include a striker assembly with a spring-loaded firing pin and downwardly-protruding firing pin flag for interaction with the trigger assembly. The trigger assemblies include a trigger, a trigger spring, a trigger bar with a connector protrusion for cooperation with a connector that can be inserted into the trigger housing, and the trigger bar is formed to cooperate with a pawl mount, and a sear is provided to cooperate with the firing pin flag.

First claim

The invention claimed is:

1. A trigger assembly for a firearm, the firearm having a striker assembly with a spring-loaded firing pin and a downwardly-protruding firing pin flag configured to cooperate with the trigger assembly, the trigger assembly comprising:
a trigger;
a trigger spring;
a trigger bar that is bent twice to form a front bent section and a rear bent section; wherein the trigger bar is movably connectable to the trigger at the front bent section, and an end portion of the rear bent section includes a connector protrusion configured to interact with a trigger housing and a connector that can be inserted into the trigger housing, where the connector has a guidance surface for the connector protrusion; and
a pawl mount, the pawl mount having:
a rear end section configured to receive and limit a tilting movement of a sear configured to cooperate with the firing pin flag about a laterally-extending sear axis;
a front section configured to be pivotably mounted in the trigger housing about a laterally-extending mount axis;
a middle section having a bearing section and an activation section, and including a catch arm formed on top of the pawl mount and protruding backward across a length of the bearing section;

wherein the sear defines a sear plane facing the firing pin flag in an installation situation, and a bearing portion for the trigger spring on a side facing away from the firing pin flag; and
the trigger bar includes a bearing protrusion that extends laterally in a direction of a center plane of the firearm from a region of the rear bent section of the trigger bar, the bearing protrusion being disposed in front of the connector protrusion and supporting the trigger spring and/or a trigger spring guide and an activation protrusion configured to interact with the pawl mount.

2. The trigger assembly according to claim 1 , wherein the pawl mount includes a connecting portion having two substantially U-shaped and upwardly bent legs.

3. The trigger assembly according to claim 2 , wherein the rear end section of the pawl mount includes a taper on inner surfaces of the legs.

4. The trigger assembly according to claim 1 , wherein the activation section of the pawl mount is inclined upward by an activation angle relative to the bearing section.

5. The trigger assembly according to claim 4 , wherein the activation angle of the activation section relative to the bearing section is between 1° and 25°.

6. The trigger assembly according to claim 4 , wherein the activation angle of the activation section relative to the bearing section is between 5° and 15°.

7. The trigger assembly according to claim 1 , wherein the bearing portion of the sear includes a collar facing the bearing protrusion in the installation situation.

8. The trigger assembly according to claim 7 , wherein the collar facing the bearing protrusion in the installation situation is circular.

9. The trigger assembly according to claim 1 , wherein the bearing portion of the sear defines a through-opening for the trigger spring guide, and the trigger spring guide is arranged inside the trigger spring.

10. The trigger assembly according to claim 1 , wherein the bearing portion of the sear defines a slot-shaped through-opening.

11. The trigger assembly according to claim 10 , wherein the slot-shaped through-opening is closed at a bottom when viewed in the installation situation.

12. The trigger assembly according to claim 1 , wherein the trigger spring guide defines a fork-shaped recess at an end of the trigger spring guide facing the bearing protrusion.

13. The trigger assembly according to claim 1 , wherein the trigger spring guide includes a T-shape at an end of the trigger spring guide facing the bearing portion of the sear.

14. The trigger assembly according to claim 1 , wherein the rear end section of the pawl mount includes a stop configured to limit a tilting movement of the sear about the sear axis.

15. The trigger assembly according to claim 1 , wherein the sear includes lateral bearing protrusions for mounting the sear in the rear end section of the pawl mount.

16. The trigger assembly according to claim 1 , wherein the sear plane of the sear has a convex contour.

17. The trigger assembly according to claim 16 , wherein, when in a rest position and viewed in a lateral direction, the sear plane follows a constant distance from the mount axis.

18. The trigger assembly according to claim 1 , wherein, when in a rest position and viewed in a lateral direction, the sear plane defines a contour that does not exhibit a constant distance to the mount axis.

19. The trigger assembly according to claim 1 , further comprising a sear rest formed on the sear plane at an end of the sear facing the firing pin flag.

20. The trigger assembly according to claim 1 , wherein the catch arm of the pawl mount defines an inlet guide.

21. A firearm, comprising a trigger assembly according to claim 1 , wherein the firearm includes a striker assembly with a spring-loaded firing pin and a downwardly-protruding firing pin flag configured to cooperate with the trigger assembly.

22. The firearm according to claim 21 , wherein the firearm is a pistol.
