Adjustable trigger assembly and method of adjusting pre-travel distance
View Patent ↗A trigger assembly apparatus for a firearm which allows adjustment of the pre-travel distance a trigger travels before initiating a firing sequence and method of making the pre-travel adjustment using the apparatus disclosed herein. The apparatus generally comprises a trigger and a trigger bow, with the trigger bow having at least one threaded receptacle in a front lateral portion thereof. The pre-travel adjustment can be achieved by rotating a threaded fastener within the threaded receptacle and the method of adjusting the pre-travel can be accomplished without complete disassembly of the firearm.

at least one externally threaded fastener; and
a bow having a first end configured for connection to the trigger and a second end opposite said first end, said bow comprising:
a front lateral cross member at the first end;
a rear lateral cross member at the second end;
a first side cross member extending between the front and rear lateral cross members;
a second side cross member extending between the front and rear lateral cross members; and
at least one threaded receptacle on the front lateral cross member, said receptacle configured to receive the at least one externally threaded fastener.
2. The trigger assembly of claim 1 wherein the front lateral cross member comprises a single, integral piece of material.
3. The trigger assembly of claim 1 where the side cross members are substantially parallel to each other.
4. The trigger assembly of claim 1 wherein the at least one threaded receptacle circumscribes an axis substantially parallel to a barrel axis of an assembled firearm when the trigger assembly is installed on said firearm.
5. The trigger assembly of claim 1 where the first and the second side cross members are each connected to the front and the rear lateral cross members.
6. The trigger assembly of claim 5 wherein the first and the second side cross members are each connected to the front and the rear lateral cross members with rounded corners.
7. The trigger assembly of claim 1 wherein the at least one externally threaded fastener comprises a first externally threaded fastener and a second externally threaded fastener and the at least one threaded receptacle comprises a first threaded receptacle and a second threaded receptacle, and wherein said first threaded receptacle is configured to receive said first externally threaded fastener and said second threaded receptacle is configured to receive said second externally threaded fastener.
8. The trigger assembly of claim 1 wherein the at least one threaded receptacle is defined within the front lateral cross member.
9. A trigger assembly for a trigger comprising:
at least one externally threaded fastener;
a bow having a first end configured for connection to the trigger and a second end opposite said first end, said bow comprising:
a front lateral cross member at the first end;
a rear lateral cross member at the second end;
a side cross member extending between the front and rear lateral cross members; and
at least one threaded receptacle on the front lateral cross member, said receptacle configured to receive the at least one externally threaded fastener.
10. The trigger assembly of claim 9 wherein the front lateral cross member comprises a single, integral piece of material.
11. The trigger assembly of claim 9 wherein the at least one threaded receptacle circumscribes an axis substantially parallel to a barrel axis of an assembled firearm when the trigger assembly is installed on said firearm.
12. The trigger assembly of claim 9 wherein the at least one externally threaded fastener comprises a first externally threaded fastener and a second externally threaded fastener and the at least one threaded receptacle comprises a first threaded receptacle and a second threaded receptacle, and wherein said first threaded receptacle is configured to receive said first externally threaded fastener and said second threaded receptacle is configured to receive said second externally threaded fastener.
13. The trigger assembly of claim 9 wherein the at least one threaded receptacle is defined within the front lateral cross member.
14. A trigger assembly for a trigger comprising:
a fastener;
a bow having a first end configured for connection to the trigger and a second end opposite said first end, said bow comprising:
a front lateral cross member at the first end;
a rear lateral cross member at the second end;
a side cross member extending between the front and rear lateral cross members; and
at least one receptacle on the front lateral cross member, said receptacle configured to receive the fastener.
15. The trigger assembly of claim 14 wherein the front lateral cross member comprises a single, integral piece of material.
16. The trigger assembly of claim 14 wherein the at least one receptacle circumscribes an axis substantially parallel to a barrel axis of an assembled firearm when the trigger assembly is installed on said firearm.
17. The trigger assembly of claim 14 wherein the at least one fastener comprises a first fastener and a second fastener and the at least one receptacle comprises a first receptacle and a second receptacle, and wherein said first receptacle is configured to receive said first fastener and said second receptacle is configured to receive said second fastener.
18. The trigger assembly of claim 14 wherein the at least one receptacle is defined within the front lateral cross member.
19. The trigger assembly of claim 14 further comprising a second side cross member extending between the front and rear lateral cross members.
20. A trigger assembly for a firearm comprising:
a bow with at least one threaded receptacle;
an externally threaded fastener configured to thread within the at least one threaded receptacle; and
wherein the at least one threaded receptacle is positioned to adjust trigger pre-travel when the bow is installed on the firearm.
21. The trigger assembly of claim 20 where the at least one threaded receptacle comprises a first threaded receptacle and a second threaded receptacle and the at least one externally threaded fastener comprises a first externally threaded fastener and a second externally threaded fastener, and wherein said first threaded receptacle is configured to receive said first externally threaded fastener and said second threaded receptacle is configured to receive said second externally threaded fastener.
