Abstract

A safety selector for a firearm, including a first lever including an integrally formed safety shaft and a first handle located outside the lower receiver for actuation, as well as a bearing portion, a selector portion and a connecting portion. To facilitate disassembly and interchangeability, the first lever is configured for spring-biased coupling to a securing element and has, on the connecting portion, a positioning protrusion projecting toward the opposite side of the weapon. In a longitudinal direction, the positioning protrusion has a shape-complementary bore for receiving a connecting assembly which includes a connecting element, a spring and a spring lock.

First claim

The invention claimed is:

1. A safety selector for a firearm, comprising:
a first lever, a securing element, and a connecting assembly;
wherein:
the first lever includes a first handle and an integrally-formed safety shaft, and is configured for a spring-biased coupling to the securing element; wherein:
the safety shaft is configured to be received in a lower receiver of the firearm and to be rotatable into at least one firing selection position, and includes a first, substantially cylindrical bearing portion joined to the first handle in a direction toward an opposite weapon side, a selector portion formed adjacent to the bearing portion and having at least one primary selector surface, and a connecting portion adjacent to the selector portion;
the first handle is configured to be outside the lower receiver for actuation of the safety selector when the safety shaft is received in the lower receiver;

the securing element includes a substantially cylindrical bearing protrusion for mounting in the lower receiver, the bearing protrusion having in a circumferential direction a primary cam configured to interact with a selector pin disposed in the lower receiver, where the primary cam also defines a mounting groove that is directed toward a weapon midplane;
the connecting assembly includes a connecting element, a spring, and a spring lock; the connecting element being configured at a first end for coupling to the spring lock and configured at its opposite, second end for coupling to the securing element;
wherein:
the first lever has, on the connecting portion of the safety shaft, a positioning protrusion projecting in a direction toward the opposite weapon side, and, in a longitudinal direction, a bore of complementary shape for receiving the connecting assembly; and
the bearing protrusion defines a coupling recess that opens outwardly in a radial direction and in the longitudinal direction and is configured to couple to the second end of the connecting element and the positioning protrusion.

2. The safety selector according to claim 1 , wherein the second end of the connecting element has at least one bolt protrusion projecting normally to the longitudinal direction, the bolt protrusion being configured to couple to the coupling recess of the securing element.

3. The safety selector according to claim 1 , wherein the second end of the connecting element and/or the spring lock has/have a non-circular cross-sectional shape.

4. The safety selector according to claim 1 , wherein the second end of the connecting element and/or the spring lock has/have an elliptical, oval, or polygonal cross-sectional shape.

5. The safety selector according to claim 1 , wherein the second end of the connecting element and/or the spring lock has/have a rectangular cross-sectional shape.

6. The safety selector according to claim 1 , wherein the coupling recess of the securing element includes a catch surface that is complementary in shape to the second end of the connecting element and/or to the positioning protrusion.

7. The safety selector according to claim 6 , wherein the second end of the connecting element includes a flattened portion that is complementary in shape to the catch surface.

8. The safety selector according to claim 1 , wherein the first end of the connecting element and the spring lock are coupled by a threaded connection.

9. The safety selector according to claim 1 , wherein the selector portion of the safety shaft includes an additional, secondary selector surface.

10. The safety selector according to claim 1 , wherein the securing element further comprises a second lever formed on the securing element, the second lever including a second handle configured to be located outside the lower receiver on the opposite weapon side for ambidextrous operation of the safety selector.

11. The safety selector according to claim 9 , further comprising a secondary cam defining a mounting groove directed toward the weapon midplane, wherein the secondary cam is formed on the bearing portion of the first lever in the circumferential direction.

12. The safety selector according to claim 11 , wherein the secondary cam is shorter in the circumferential direction than the primary cam.

13. The safety selector according to claim 12 , wherein the secondary cam extends over a second selector angle of 40° to 80°.

14. The safety selector according to claim 12 , wherein the secondary cam extends over a second selector angle of approximately 55°.

15. The safety selector according to claim 1 , further comprising a closing protrusion is formed on the connecting portion that is configured to cover the mounting groove when the safety selector is in an installed state.

16. The safety selector according to claim 1 , wherein the bore is configured as a stepped bore.

17. The safety selector according to claim 1 , further comprising at least one interacting positioning aid pair formed on the connecting portion and the securing element.
