A safety mechanism for a firearm includes a cam selector, a lever, and a trigger. The cam selector comprises a first end, a second end, a top side, and a bottom side. The cam selector comprises a longitudinal slot positioned on the top side of the cam selector. The lever comprises a proximal end and a distal end. The longitudinal slot is configured to receive the lever. The cam selector further comprises a first recess and a second recess on the bottom side of the cam selector. The trigger comprises a first trigger tail portion. In addition to the standard semi-automatic and safe modes, the present invention provides an additional active reset mode in which the cam selector is configured to allow the first trigger tail portion to engage the second recess and be moved down by a cam portion of the second recess when the cam selector rotates.
A trigger mechanism that can be used in AR-pattern firearms has a hammer, a trigger member, a disconnector, a cam, and a “three position” safety selector having safe, standard semi-automatic, and forced reset semi-automatic positions. In the standard semi-automatic position, rearward movement of the bolt carrier causes rearward pivoting of the hammer and pivoting of the cam from a first position to a second position such that a cam lobe forces the trigger member towards the set position, but prior to reaching the set position the disconnector hook catches the hammer hook, at which time a user must manually release the trigger member to free the hammer from the disconnector to permit the hammer and trigger member to pivot to their set positions so that the user can pull the trigger member to fire the firearm. In the forced reset semi-automatic position, rearward movement of the bolt carrier causes rearward pivoting of the hammer and pivoting of the cam from the first position to the second position such that the cam lobe forces the trigger member to the set position, the safety selector preventing the disconnector hook from catching the hammer hook, at which time the user can pull the trigger member to fire the firearm without manually releasing the trigger member.

In the forced reset semi-automatic position, rearward movement of the bolt carrier causes rearward pivoting of the hammer causing the trigger member to be forced to the set position, the safety selector preventing the disconnector hook from catching the hammer hook, and thereafter when the bolt carrier reaches the substantially in-battery position the user can pull the trigger member to fire the firearm without manually releasing the trigger member. The locking member is pivotable between a first position at which the locking member mechanically blocks the trigger member from moving to the released position and a second position at which the locking member does not mechanically block the trigger member allowing the trigger member to be moved to the released position. The locking member is spring biased toward the first position and moved against the spring bias to the second position by contact from the bolt carrier during forward movement of the bolt carrier as the bolt carrier reaches a substantially in-battery position.

In a forced rest trigger mechanism, provided is an extended trigger member locking device having a locking member that is movable between a first position in which it locks a trigger member against pulling movement and a second position where it does not restrict movement of the trigger member. The locking member is configured to be movably supported by a frame and includes a generally upward extension portion configured to make actuating contact with a surface of a bolt carrier. The locking member has a body portion that is movably supported and an upward extension portion that is separately movable relative to the body portion between an extended position and a deflected position.

Forced reset semiautomatic trigger with sliding blocking bar
Provided is a trigger mechanism for a firearm having a receiver with a fire control mechanism pocket and a bolt carrier that reciprocates to pivotally displace a hammer when cycled. It includes a hammer having a sear notch and mounted in the fire control mechanism pocket to pivot on a transverse axis between set and released positions. A trigger member has a sear and is mounted in the fire control mechanism pocket to pivot on a transverse axis between set and released positions. The trigger member has a first surface positioned to be forcibly contacted by the hammer when the hammer is displaced by cycling of the bolt carrier, the contact causing at least in part the trigger member to be forced to the set position. A locking bar is slideably mounted in a support frame and spring biased toward a first position in which the locking bar mechanically blocks the trigger member from moving to the released position, and is movable against the spring bias to a second position when contacted by the bolt carrier reaching a substantially in-battery position, allowing the trigger member to be moved by an external force to the released position.
A trigger activated arm may use a piston moving within a cylinder to dampen gun bolt speed. In some embodiments, gun bolt motion increases pressure within the cylinder bore to dampen rearward gun bolt speed. The pressure may be high enough to unseat the cylinder creating a vent that cylinder fluid exits. In other embodiments, gun bolt motion decreases pressure within the cylinder bore to dampen forward gun bolt speed.

A trigger activated arm may use engagement of an integrated gun bolt cam with an integrated trigger cam to reposition the trigger as the gun bolt reciprocates. The gun bolt trigger engagement may be used to reset the trigger.
A handheld finger activated semi-automatic arm may include a barrel, a trigger, a moveable gun bolt and a trigger reset mechanism. The trigger reset mechanism may use rigid mechanical contact between the trigger and the gun bolt during an earliest portion of the operating cycle. The trigger may be blocked from depression by the gun bolt up to 99% of the operating cycle.
