US12474139 - Gas powered semi-automatic airgun action

The patent describes a gas-powered semi-automatic airgun that utilizes a valve and a hammer mechanism to release pressurized gas for firing. It features a dual sear system and a trigger mechanism designed to facilitate the transition between firing and non-firing positions, enhancing operational efficiency.

Claim 1

1 . An airgun, comprising: a valve for releasing pressurized gas when transitioned from a closed position to an open position; a hammer that causes the valve to release the pressurized gas; a primary sear that facilitates movement of the hammer between a hammer cocked position and a hammer fire position; a secondary sear that facilitates movement of the primary sear between a primary sear cocked position and a primary sear fire position; a trigger movable between a non-firing position and a fired position; and a lift connected to the secondary sear, the lift engaged with the trigger in the non-firing position and disengaged from the trigger in the fired position, the lift facilitating movement of the secondary sear from a secondary sear cocked position to a secondary sear fire position when the trigger is in the fired position, wherein: a trigger spring is positioned to bias the trigger toward the non-firing position, and movement of the trigger from the fired position to the non-firing position causes reengagement between the lift and the trigger. a valve for releasing pressurized gas when transitioned from a closed position to an open position; a hammer that causes the valve to release the pressurized gas; a primary sear that facilitates movement of the hammer between a hammer cocked position and a hammer fire position; a secondary sear that facilitates movement of the primary sear between a primary sear cocked position and a primary sear fire position; a trigger movable between a non-firing position and a fired position; and a lift connected to the secondary sear, the lift engaged with the trigger in the non-firing position and disengaged from the trigger in the fired position, the lift facilitating movement of the secondary sear from a secondary sear cocked position to a secondary sear fire position when the trigger is in the fired position, wherein: a trigger spring is positioned to bias the trigger toward the non-firing position, and a trigger spring is positioned to bias the trigger toward the non-firing position, and movement of the trigger from the fired position to the non-firing position causes reengagement between the lift and the trigger.
