Abstract
Trigger assemblies that preserve the integrity of the trigger sear surface when the trigger assembly enters a “half-cocked”, safety configuration are disclosed. In certain embodiments, a trigger safety engagement surface engages a hammer safety engagement surface in the safety configuration, preventing the hammer from rotating into contact with a firing pin. In some instances, the trigger sear surface is suspended within a safety recess (e.g., a notch) of the hammer and free of contact with the hammer when the trigger assembly is in the safety configuration.
Claims20
A trigger assembly for striking a firing pin of a firearm, the trigger assembly comprising:
- a trigger having a trigger sear surface and a hammer having a hammer sear surface;
- wherein the hammer is rotatable a first angular distance from a stable cocked position to a stable safety position;
- wherein the hammer is rotatable a second angular distance from the stable cocked position to a stable uncocked position in contact with the firing pin;
- wherein in the stable cocked position the trigger sear surface engages the hammer sear surface;
- wherein in the stable safety position the trigger sear surface is free of engagement with the hammer;
- and
- wherein the first angular distance is at least half of the second angular distance.
An assembly for a firearm having a firing pin, the assembly comprising:
- a trigger having a trigger sear surface and a hammer having a hammer sear surface;
- wherein the hammer is rotatable from a cocked position to a partially-cocked position and from the cocked position to a uncocked position in contact with the firing pin;
- wherein in the cocked position the trigger sear surface engages the hammer sear surface and resists the hammer from rotating until the trigger sear surface is moved out of engagement with the hammer sear surface;
- wherein in the partially-cocked position the trigger sear surface is free of engagement with the hammer;
- and
- wherein in the partially-cocked position a trigger release barrier surface of the trigger is arranged to engage a hammer release barrier surface of the hammer to initially prevent further movement of the trigger from releasing the hammer.
A product, comprising:
- a single-stage trigger and hammer assembly having a trigger with a trigger sear surface and a hammer with a hammer sear surface;
- wherein the hammer is rotatable from a static cocked position to a static safety position;
- wherein when the hammer is in the static cocked position the trigger sear surface engages the hammer sear surface;
- and
- wherein when the hammer is in the static safety position the trigger sear surface is free of engagement with the hammer.
