Firearm trigger mechanism, firearm and method of controlling a rate of the firearm
View Patent ↗A trigger mechanism for a firearm, the trigger mechanism having: a trigger for actuating a hammer of the trigger mechanism, wherein actuation of the trigger causes the hammer to advance to a firing position; and a release configured for movement between a first position and a second position, the release must be first actuated from the first position to the second position and thereafter from the second position to the first position in order to allow for the hammer to advance to the firing position.
1. A trigger mechanism for a firearm, the trigger mechanism comprising:
a trigger operatively coupled to a hammer of the trigger mechanism, wherein actuation of the trigger advances the hammer to a firing position; and
a release comprising a blocking member movably mounted to a lower receiver of the firearm for movement between a first position and a second position, wherein a portion of the blocking member impedes movement of a bolt carrier assembly when the blocking member is in the first position and wherein the blocking member does not impede movement of the bolt carrier assembly when the blocking member is in the second position, wherein the blocking member is biased into the first position and wherein the blocking member must be first moved from the first position to the second position and thereafter from the second position to the first position in order for the hammer to advance to the firing position after actuation of the trigger.
2. The trigger mechanism as in claim 1 , wherein the blocking member is spring biased into the first position.
3. The trigger mechanism as in claim 1 , wherein the blocking member is pivotally mounted to the lower receiver.
4. The trigger mechanism as in claim 1 , wherein the blocking member is operatively coupled to an actuation member movably mounted to the lower receiver such that movement of the actuation member moves the blocking member between the first position and the second position.
5. The trigger mechanism as in claim 4 , wherein the actuation member is slidably mounted to the lower receiver and is operatively coupled to a release button pivotally mounted to the lower receiver.
6. The trigger mechanism as in claim 1 , wherein the blocking member is moved between the first position and the second position by an actuation member operatively coupled to the blocking member such that movement of the actuation member from a first position to a second position by a release button operatively coupled to the actuation member moves the blocking member between the first position and the second position, wherein the release button is movably mounted to the lower receiver, and wherein the actuation member is impedes movement of the hammer to the firing position when the actuation member is in the second position.
7. The trigger mechanism as in claim 6 , wherein the actuation member allows movement of the hammer to the firing position when the actuation member is in the first position.
8. The trigger mechanism as in claim 6 , wherein the actuation member has a protrusion that impedes movement of the hammer to the firing position when actuation member is in the second position.
9. The trigger mechanism as in claim 8 , wherein the protrusion does not impede movement of the hammer to the firing position when the actuation member is in the first position.
10. A firearm, comprising:
a barrel;
a bolt carrier assembly movably received within the firearm for movement between a first position and a second position;
a trigger mechanism for firing a round from the firearm, the trigger mechanism comprising:
a trigger;
a hammer pivotally mounted to the firearm for movement between a first position and a second position, wherein actuation of the trigger causes the hammer to advance from the first position to the second position, wherein the hammer contacts a firing pin of the firearm;
a release comprising a blocking member movably mounted to a lower receiver of the firearm for movement between a first position and a second position, wherein a portion of the blocking member impedes movement of a bolt carrier assembly when the blocking member is in the first position and wherein the blocking member does not impede movement of the bolt carrier assembly when the blocking member is in the second position, wherein the blocking member is biased into the first position and wherein the blocking member must be first moved from the first position to the second position and thereafter from the second position to the first position in order for the hammer to advance to the second position after a round has been fired from the firearm.
11. The firearm as in claim 10 , wherein the blocking member is spring biased into the first position.
12. The firearm as in claim 10 , wherein the blocking member is pivotally mounted to the lower receiver.
13. The firearm as in claim 10 , further comprising an actuation member movably mounted to the lower receiver and operatively coupled to the blocking member for moving the blocking member between the first position and the second position.
14. The firearm as in claim 13 , wherein the actuation member is slidably mounted to the lower receiver and is actuated by a release button pivotally mounted to the lower receiver.
15. The firearm as in claim 10 , wherein the blocking member is moved between the first position and the second position by an actuation member operatively coupled to the blocking member and wherein the actuation member is movably mounted to the lower receiver for movement between first position and a second position by a release button operatively coupled to the actuation member and wherein the release button is mounted to the lower receiver, wherein the actuation member impedes movement of the hammer to the second position when the actuation member is in the second position.
16. The firearm as in claim 15 , wherein the actuation member allows movement of the hammer to the firing position when the actuation member is in the first position.
17. The firearm as in claim 15 , wherein the actuation member has a protrusion that impedes movement of the hammer to the firing position when actuation member is in the second position, wherein the protrusion does not impede movement of the hammer to the firing position when the actuation member is in the first position.
18. A method of controlling the firing rate of a firearm, comprising:
limiting movement of a bolt carrier assembly of the firearm to a position such that a trigger of the firearm cannot fire another round from the firearm after a first round has been fired from the firearm; and
releasing the bolt carrier assembly from the position to another position, wherein actuation of the trigger causes a hammer to contact a firing pin of the bolt carrier assembly, wherein the releasing of the bolt carrier assembly from the position is achieved by actuation of a release button located on a surface of the firearm proximate to the trigger, wherein the release button is operatively coupled to a blocking member movably mounted to a lower receiver of the firearm for movement between a first position and a second position, wherein a portion of the blocking member impedes movement of the bolt carrier assembly when the blocking member is in the first position and wherein the blocking member does not impede movement of the bolt carrier assembly when the blocking member is in the second position, wherein the blocking member is biased into the first position and wherein blocking member is moved to the second position via actuation of the release button.
