Trigger assembly for a firearm
A trigger assembly for a firearm has a frame, a trigger element pivotally connected to the frame and having a trigger lever operable for movement between a forward released position and a rearward actuated position, a hammer pivotally connected to the frame and movable between a cocked position and a striking position, a shroud element pivotally connected to the frame and having a shroud lever operable for movement between a forward disabling position and a rearward enabling position, a link pivotally connected to the frame and having a first portion operably interfacing the reciprocating action element and a second portion operably interfacing the shroud element, and the link being operable when the reciprocating action element moves from the rear recoil position to the forward battery position to motivate the shroud element from the rearward enabling position to the forward disabling position.
1 . A trigger assembly for a firearm having a reciprocating action element movable between a rear recoil position and a forward battery position, the trigger assembly comprising:
a frame;
a trigger element pivotally connected to the frame and having a trigger lever operable for movement between a forward released position and a rearward actuated position;
a hammer pivotally connected to the frame and movable between a cocked position and a striking position;
a shroud element shrouding the trigger lever and pivotally connected to the frame having a shroud lever operable for movement between a forward disabling position in which a user's finger cannot move the trigger lever when pulling the shroud lever and a rearward enabling position in which the user's finger also moves the trigger lever when pulling the shroud lever;
a link pivotally connected to the frame and having a first portion operably interfacing the reciprocating action element and a second portion operably interfacing the shroud element; and
the link being operable when the reciprocating action element moves from the rear recoil position to the forward battery position to motivate the shroud element from the rearward enabling position to the forward disabling position.
2 . The trigger assembly of claim 1 wherein the shroud element and trigger element pivot about a common axis.
3 . The trigger assembly of claim 1 including a selector interfacing the link and movable between a first operating condition in which link movement is enabled to motivate the shroud element and a second operating condition in which link movement is disabled from motivating the shroud element.
4 . The trigger assembly of claim 3 wherein the selector interfaces the trigger element and is movable to a third position in which operation of the trigger element is disabled.
5 . The trigger assembly of claim 1 wherein the link is movable between an inactive position enabling the shroud lever to be in the rearward enabling position, and a link active position contacting the shroud lever.
6 . The trigger assembly of claim 5 wherein the link is operable in response to a forward force by the reciprocating action element on the first link portion to transmit a biasing force on the shroud element to bias the shroud lever toward the forward disabling position.
7 . The trigger assembly of claim 1 wherein the shroud lever is forward of the trigger lever when the shroud lever is in the disabling position.
8 . The trigger assembly of claim 1 wherein the hammer interfaces a forward portion of the reciprocating action element, and the link interfaces the reciprocating action element at a bolt assembly surface rearward of the forward portion of the reciprocating action element.
9 . The trigger assembly of claim 1 wherein the reciprocating action element is a reciprocating bolt assembly.
