Abstract

Techniques and componentry are disclosed for an air gun with an adjustable trigger mechanism. The air gun includes a cylinder attached to a barrel and a trigger mechanism. The trigger mechanism includes a sear operatively coupled to a trigger bar and configured to release a piston disposed within the cylinder in response to operating the trigger mechanism. Operatively coupled to the trigger bar is a trigger blade that includes a trigger stage bracket. The trigger stage bracket provides a second pull stage that operates with more resistance than a first pull stage during trigger blade movement. An adjustment screw is disposed within the trigger blade and is in contact with the trigger stage bracket. The adjustment screw positions the trigger stage bracket relative to the trigger blade to adjust a distance at which the trigger blade transitions from the first pull stage to the second pull stage.

First claim

What is claimed is:

1. An air gun comprising:
a barrel attached to a cylinder; and
a trigger mechanism including
a sear operatively coupled to a trigger bar, the sear is configured to release a piston disposed within the cylinder in response to operating the trigger mechanism,
a trigger blade operatively coupled to the trigger bar and including a trigger stage bracket, the trigger stage bracket to provide a first pull stage and a second pull stage, wherein the second pull stage operates with more resistance force than the first pull stage during movement of the trigger blade, and
an adjustment screw disposed within the trigger blade and in contact with the trigger stage bracket, the adjustment screw to position of the trigger stage bracket relative to the trigger blade to adjust a distance at which the trigger blade is to transition from the first pull stage to the second pull stage.

2. The air gun of claim 1 , wherein the trigger stage bracket includes a first stage feature in contact with the trigger bar during the first pull stage, and a second stage feature in contact with the trigger bar during the second pull stage.

3. The air gun of claim 2 , wherein the first stage feature is in contact with the trigger bar and the second stage feature is not in contact with the trigger bar while the trigger blade is operated through the first pull stage.

4. The air gun of claim 2 , wherein the first stage feature and the second stage feature are in contact with the trigger stage bracket at the distance at which the trigger blade is to transition from the first pull stage to the second pull stage.

5. The air gun of claim 2 , wherein the first stage feature and the second stage feature are curvilinear surfaces.

6. The air gun of claim 2 , wherein at least one of the first stage feature and the second stage feature includes a rotating bearing element.

7. The air gun of claim 2 , wherein contact between the trigger bar and the trigger stage bracket is along a surface of at least one of the first stage feature and the second stage feature.

8. The air gun of claim 1 , wherein the trigger blade is configured to limit movement of the trigger stage bracket relative to the trigger blade.

9. The air gun of claim 1 , wherein the trigger mechanism includes only one adjustment screw to adjust the distance at which the trigger blade is to transition from the first pull stage to the second pull stage.
