Abstract
A trigger lock is shown which rotates from a fire position in which the trigger can operate and to a no-fire position in which the trigger cannot operate. The lock is located primarily within the frame. A thumb lever or a key can be used to engage the trigger lock to rotate the trigger lock from the fire to the no-fire position and vice versa.
Claims12
A trigger lock affixed in a frame of a weapon for allowing a trigger of the weapon to operate when the lock is in a fire position and preventing operation of the trigger of the weapon when the lock is in a no-fire position, the trigger lock comprising:
- a shaft having a work end on one end and an indicator shaft on an opposite end, a cutout located between the work end and the indicator shaft, the shaft housed in the frame;
- at least one shaft cavity on the shaft end near the work end;
- a spring located on the indicator shaft for biasing the shaft in the frame;
- a bushing having at least one bushing ear on a first end with a bore extending from the first end through the second end, the bushing housed in the frame and the second end exposed to the exterior of the frame, the bushing ear for engagement with the shaft cavity of the shaft;
- and
- a key for insertion through the bore for engaging the work end of the shaft, the key for causing a translation and rotation of the shaft from a fire position to a no-fire position and from a no-fire position to a fire position.
A trigger lock housed in a frame of a weapon, where each end of the trigger lock is exposed to the exterior of the frame, the trigger lock for allowing a trigger to operate when the trigger lock is in a fire position and not allowing the trigger to operate when the trigger is in a no-fire position, the trigger lock comprising:
- a shaft having an indicator shaft on one end and a work end adjacent a shaft cavity on an opposite end, a retainer located near the indicator shaft, a cutout located between the indicator shaft and work end;
- a spring for insertion over the indicator shaft and contained between a shoulder and the retainer;
- a bushing inserted in the frame for retaining the shaft within the frame, the bushing having a bore there through and at least one bushing ear on one end;
- and
- a key for insertion through the bore and for engaging the work end for translation and rotation of the shaft, where rotation of the shaft to a preset position places the cutout into a position such that the trigger will fire and the rotation of the shaft from the fire position will orient the cutout such that the trigger will be in the no-fire position.
