Firearm safety
In one general aspect, the subject matter described in this specification can be embodied in a firearm safety device including a trigger, a pin, and a safety deactuation device. The trigger has a channel therein with an opening at an end of the channel. The pin is disposed within the channel such that a portion of the pin extends through the opening. The safety deactuation device is configured to engage with the pin and move the pin within the channel of the trigger as the safety deactuation device is moved relative to the trigger.
1. A firearm safety device comprising:
a trigger comprising a channel therein with an opening at an end of the channel;
a pin disposed within the channel such that a portion of the pin extends through the opening; and
a cover at least partially enclosing the trigger and configured to move relative to the trigger, the cover comprising a cam channel configured to engage with the pin and move the pin within the channel of the trigger as the cover moves relative to the trigger.
2. The device of claim 1 , wherein the pin is sized such that the portion of the pin can extend through the opening to engage with a hole in a firearm frame.
3. The device of claim 1 , further comprising a spring disposed within the channel of the trigger.
4. The device of claim 1 , wherein the pin is “T” shaped.
5. The device of claim 1 , wherein the pin comprises at least one post extending substantially perpendicular to an axis of the pin, the post configured to engage the cam channel in the cover.
6. The device of claim 1 , wherein the trigger is a straight-pull trigger.
7. The device of claim 1 , further comprising a trigger bar coupled to the trigger.
8. The device of claim 1 , wherein an angle between the cam channel and an axis of the channel in the trigger is more than 10 and less than 90 degrees.
9. The device of claim 1 , wherein an angle between the cam channel and an axis of the channel in the trigger is between 35 and 55 degrees.
10. A firearm comprising:
a frame; and
a trigger assembly installed within the frame, the trigger assembly comprising:
a trigger comprising a channel therein with an opening at an end of the channel;
a pin disposed within the channel such that a portion of the pin extends through the opening and into a hole in the frame, when the pin is in a first position; and
a safety deactuation device configured to engage with the pin and move the pin into a second position within the channel of the trigger as the safety deactuation device is moved relative to the trigger, wherein the safety deactuation device comprises a cover at least partially enclosing the trigger and configured to move relative to the trigger.
11. The firearm of claim 10 , wherein, when the pin is in the first position, the pin prevents the trigger from moving.
12. The firearm of claim 10 , wherein, when the pin is in the second position, the trigger is free to move.
13. The firearm of claim 10 , further comprising a spring disposed within the channel of the trigger.
14. The firearm of claim 10 , wherein the cover comprises a cam channel configured to engage with the pin and move the pin within the channel of the trigger as the cover moves relative to the trigger.
15. The firearm of claim 10 , wherein the pin comprises at least one post extending substantially perpendicular to an axis of the pin, the post configured to engage a cam channel in the cover.
16. The firearm of claim 15 , wherein an angle between the cam channel and an axis of the channel in the trigger is between 40 and 50 degrees.
17. A firearm safety device comprising:
a trigger comprising a channel therein with an opening at an end of the channel;
a pin disposed within the channel such that a portion of the pin extends through the opening; and
a safety deactuation device configured to engage with the pin and move the pin within the channel of the trigger as the safety deactuation device is moved relative to the trigger, wherein the safety deactuation device comprises a cover at least partially enclosing the trigger and configured to move relative to the trigger.
18. The device of claim 17 , wherein the cover comprises a cam channel configured to engage with the pin and move the pin within the channel of the trigger as the cover moves relative to the trigger.
