Abstract

A trigger assembly cooperates with a planar interlock, wherein the plane of the interlock includes a longitudinal axis of the barrel in a break barrel airgun. The trigger assembly includes a primary sear and a secondary sear, wherein the secondary sear is contacted by the interlock during cocking of the airgun. The contact of the interlock and the secondary sear is independent of a position of a safety in the trigger assembly.

Claims

1. A trigger assembly comprising:

(a) a housing having first and second spaced opposing side walls;

(b) a trigger and a safety at least partially located between the opposing side walls;

(c) a primary sear and a secondary sear located between the opposing side walls, wherein the secondary sear rotates about a pivot between a safety position and a release position, the primary sear includes a first contact surface and a spaced apart second contact surface and the secondary sear includes a first guide surface and a second guide surface, the first contact surface contacting the first guide surface and the second contact surface contacting the second guide surface; and

(d) an interlock, the interlock moveable between (i) an interlocked position contacting the secondary sear to at least one of (a) inhibit a firing movement of the secondary sear and (b) urge movement of the secondary sear to the safety position and (ii) a shooting position permitting movement of the secondary sear to the release position.

2. The trigger assembly of claim 1, wherein each of the first and second spaced opposing side walls includes a shoulder and the safety includes a main body and a projecting arm, the main body having spaced sliding surfaces for engaging the corresponding shoulders of the housing.

3. The trigger assembly of claim 1, wherein the safety includes a main body defining an elongate slot having a varying cross section and a spaced biasing slot, the elongate slot and the biasing slot separated by a bridge, the bridge flexing in response to a pin passing from a first end of the elongate slot to a second end of the elongate slot.

4. The trigger assembly of claim 1, further comprising a connecting wall interconnecting the first and second spaced opposing side walls.

5. The trigger assembly of claim 1, wherein the first contact surface and the second contact surface of the primary sear are cylindrical.

6. The trigger assembly of claim 1, wherein the first guide surface and the second guide surface of the secondary sear are curvilinear.

7. The trigger assembly of claim 1, wherein the first contact surface and the second contact surface of the primary sear are cylindrical and fixed with respect to a remaining portion of the primary sear.

8. The trigger assembly of claim 1, wherein the housing is connected to a gun having a barrel and the interlock is parallel to the barrel.

9. The trigger assembly of claim 1, wherein the interlock extends between the opposing sidewalls.
