US12398975 - Trigger assembly for air gun

The patent describes a trigger assembly for an air gun that includes an actuator, primary sear, catch, trigger, and secondary sear, designed to facilitate automatic re-cocking after firing. Upon pulling the trigger, the assembly allows the actuator to release and fire the air gun, then re-cocks itself for subsequent use.

Claim 1

1. A trigger assembly comprising: an actuator configured to move along a longitudinal axis, the actuator having a leading surface and a trailing surface; a primary sear configured to rotate about a first pivot, the primary sear including a first protrusion proximate a leading end of the primary sear and a second protrusion proximate a trailing end of the primary sear, the primary sear further comprising a catch engagement surface proximate the trailing end of the primary sear; a catch configured to rotate about a second pivot spaced from the first pivot; a trigger configured to pivot about the second pivot relative to the catch; and a secondary sear configured to rotate about a third pivot, wherein: with the trigger assembly in a cocked configuration, the first top protrusion of the primary sear contacts the leading surface of the actuator to retain the actuator in a cocked position and the secondary sear contacts the primary sear to resist pivoting of the primary sear, in response to rotation of the trigger about the second pivot to a firing position, the trigger contacts the secondary sear, causing the secondary sear to rotate about the third pivot to facilitate movement of the primary sear about the first pivot, the movement of the primary sear about the first pivot causing the first top protrusion of the primary sear to release the actuator, the release of the actuator causes the actuator to move along the barrel axis in a first direction to fire the air gun, after firing of the air gun, the actuator moves in a second direction along the barrel axis to contact the second protrusion of the primary sear, causing the primary sear to pivot about the primary sear to a re-cocking position in which the catch engagement surface of the primary sear engages the catch and the catch retains the primary sear in a position to contact the leading surface of the actuator with the first protrusion of the primary sear, and releasing the trigger with the catch engaged causes, in order, the secondary sear to return to a position that engages the primary sear and causes the catch to disengage from the catch engaging surface, thereby placing the air gun in the cocked configuration. an actuator configured to move along a longitudinal axis, the actuator having a leading surface and a trailing surface; a primary sear configured to rotate about a first pivot, the primary sear including a first protrusion proximate a leading end of the primary sear and a second protrusion proximate a trailing end of the primary sear, the primary sear further comprising a catch engagement surface proximate the trailing end of the primary sear; a catch configured to rotate about a second pivot spaced from the first pivot; a trigger configured to pivot about the second pivot relative to the catch; and a secondary sear configured to rotate about a third pivot, wherein: with the trigger assembly in a cocked configuration, the first top protrusion of the primary sear contacts the leading surface of the actuator to retain the actuator in a cocked position and the secondary sear contacts the primary sear to resist pivoting of the primary sear, in response to rotation of the trigger about the second pivot to a firing position, the trigger contacts the secondary sear, causing the secondary sear to rotate about the third pivot to facilitate movement of the primary sear about the first pivot, the movement of the primary sear about the first pivot causing the first top protrusion of the primary sear to release the actuator, the release of the actuator causes the actuator to move along the barrel axis in a first direction to fire the air gun, after firing of the air gun, the actuator moves in a second direction along the barrel axis to contact the second protrusion of the primary sear, causing the primary sear to pivot about the primary sear to a re-cocking position in which the catch engagement surface of the primary sear engages the catch and the catch retains the primary sear in a position to contact the leading surface of the actuator with the first protrusion of the primary sear, and releasing the trigger with the catch engaged causes, in order, the secondary sear to return to a position that engages the primary sear and causes the catch to disengage from the catch engaging surface, thereby placing the air gun in the cocked configuration. with the trigger assembly in a cocked configuration, the first top protrusion of the primary sear contacts the leading surface of the actuator to retain the actuator in a cocked position and the secondary sear contacts the primary sear to resist pivoting of the primary sear, in response to rotation of the trigger about the second pivot to a firing position, the trigger contacts the secondary sear, causing the secondary sear to rotate about the third pivot to facilitate movement of the primary sear about the first pivot, the movement of the primary sear about the first pivot causing the first top protrusion of the primary sear to release the actuator, the release of the actuator causes the actuator to move along the barrel axis in a first direction to fire the air gun, after firing of the air gun, the actuator moves in a second direction along the barrel axis to contact the second protrusion of the primary sear, causing the primary sear to pivot about the primary sear to a re-cocking position in which the catch engagement surface of the primary sear engages the catch and the catch retains the primary sear in a position to contact the leading surface of the actuator with the first protrusion of the primary sear, and releasing the trigger with the catch engaged causes, in order, the secondary sear to return to a position that engages the primary sear and causes the catch to disengage from the catch engaging surface, thereby placing the air gun in the cocked configuration.
