Abstract
A firearm with dual-acting safety mechanism includes a hammer, sear operable to hold the hammer in a cocked position, and trigger mechanism including a trigger and trigger bar which collectively operates to rotate the sear to release the hammer. The safety mechanism includes a safety mode selector or actuator cooperating with a secondary safety link. In one arrangement, linearly moving the selector actuates and rotates the safety link which simultaneously both blocks the hammer and displaces the trigger bar such that the sear can no longer be actuated via a trigger pull.
Claims21
A firearm with safety mechanism comprising:
- a longitudinal axis;
- a frame;
- a hammer pivotably disposed in the frame, the hammer moveable between a rearward cocked position and a forward firing position;
- a sear pivotably disposed in the frame and configured to hold the hammer in the rearward cocked position;
- a trigger mechanism comprising a trigger and trigger bar movable therewith, the trigger bar movable to selectively engage the sear for releasing the hammer from the cocked position via a trigger pull to discharge the firearm;
- a manually-operated safety mechanism comprising a movable actuator and a pivotably movable safety link operably interfaced with the actuator, the safety link actuatable via moving the actuator between first and second positions;
- the safety link comprising a first protrusion arranged to selectively engage the hammer when the safety link is actuated, and a second protrusion arranged to selectively engage the trigger bar when the safety link is actuated;
- wherein via moving the actuator, the safety mechanism is changeable between a fire position in which the safety link is disengaged from the hammer and trigger bar which allows the firearm to be discharged in response to a trigger pull, and a safe position in which the safety link is engaged with the hammer and trigger bar to prevent the firearm from being discharged in response to a trigger pull;
- wherein the actuator is axially movable between the first and second positions, and the safety link via operation of the safety actuator is pivotably movable between an upper unactuated position disengaged from the hammer and trigger bar, and a lower actuated position engaged with the hammer and trigger bar;
- wherein the actuator comprises a lateral camming protrusion which slideably engages an arcuately curved camming surface on the safety link to rotate the safety link from the upper position to lower position when the actuator is moved;
- and
- further comprising a locking notch formed at one end of the camming surface of the safety link which selectively engages a complementary configured locking protrusion formed on the camming protrusion of the actuator.
A firearm with dual-acting safety mechanism comprising:
- a longitudinal axis;
- a frame;
- a hammer pivotably movable in the frame, the hammer moveable between a rearward cocked position and a forward firing position;
- a sear pivotably movable in the frame and configured to hold the hammer in the rearward cocked position;
- a trigger mechanism comprising a pivotably movable trigger and a trigger bar movably coupled to the trigger, the trigger bar axially moveable via pulling the trigger to selectively engage and rotate the sear for releasing the hammer from the cocked position to discharge the firearm;
- a manually-operated safety mechanism comprising an axially slideable safety mode selector and a pivotably movable safety link, the safety link moveable between unactuated and actuated positions via sliding the actuator between first and second axial positions;
- the safety link comprising a first nose protrusion on one lateral side of the firearm which is selectively operable when the safety link is in the actuated position to engage and block rotation of the hammer to prevent discharging the firearm;
- the safety link further comprising a second foot protrusion on an opposite lateral side of the firearm which is selectively operable when the safety link is in the actuated position to engage and displace the trigger bar such that the trigger bar is prevented from engaging and rotating the sear to prevent discharging the firearm;
- wherein the nose and foot protrusions are structurally linked together via a cross member such that moving one of the nose or foot protrusion simultaneously moves the other of the nose or foot protrusion;
- wherein the actuator comprises an elongated actuating member for grasping by a user disposed on one lateral side, and a laterally projecting camming protrusion disposed on an opposite lateral side which slideably engages the safety link to change the safety link between the upper and lower positions;
- wherein the camming protrusion engages a corresponding arcuately curved camming surface on the nose protrusion of the safety link which pivotably moves both the nose and foot protrusions in unison.
