ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates generally to locking mechanisms for use in firearms and more particularly to a lock that blocks the firing pin of a firearm. The invention is particularly suitable for blocking the firing pin of a bolt action firearm. Regardless of the type of firearm in which the present invention is incorporated, it provides an additional means by which firearms can be secured to deter unauthorized use.
SUMMARY OF THE INVENTION
The various embodiments of the locking mechanisms of the present invention provide an integral device that can assist in deterring unauthorized use of a firearm by providing a lock that can be activated to prevent the firing pin from moving.
Specifically, the present invention provides a firearm having a firing pin and a locking mechanism comprising: a lock button, rotatable between an unlocked position, wherein the lock button permits movement of the firing pin, and a locked position, wherein the lock button prevents movement of the firing pin, wherein the lock button comprises a longitudinal axis, a surface, and a first end and a second end, and; i. a locking aperture formed along the longitudinal axis of the button and comprising a female receiving end formed in the first end of the button; ii. a notch formed in the surface of the button between the first and second ends of the button; and iii. a plunger aperture formed in the surface of the button between the first and second ends of the button, and wherein the locking mechanism further comprises a detent plunger and a locking means for insertion into the female receiving end of the locking aperture of the safety button, and wherein the plunger aperture is connected to the locking aperture, and wherein the firing pin has a notch formed therein positioned and configured to interact with the notch of the lock button.
The present invention also provides a bolt action firearm having a bolt assembly comprising a hollow bolt body, a bolt handle, a bolt plug, a firing pin and firing pin spring within the bolt body, and a locking mechanism comprising a lock button having a longitudinal axis, a surface, and a first end and a second end, and comprising; i. a locking aperture formed along the longitudinal axis of the button and comprising a female receiving end formed in the first end of the button; ii. a notch formed in the surface of the button between the first and second ends of the button; and iii. a plunger aperture formed in the surface of the button between the first and second ends of the button and connected to the locking aperture, and wherein the locking mechanism further comprises a detent plunger, and a locking means for insertion into the female receiving end of the locking aperture of the safety button, and wherein the lock button is moveable among a locked and an unlocked position, and wherein the firing pin has a notch formed therein positioned and configured to interact with the notch of the lock button to permit movement of the firing pin when the lock button is in the unlocked position and to prevent movement of the firing pin when the lock button is in the locked position.
In addition, the present invention provides a firearm having a firing pin and a locking mechanism comprising: A. a lock button having a longitudinal axis, a surface, a first end and a second end, and comprising: i. a locking aperture formed along a the longitudinal axis of the button comprising a female receiving end formed in the first end of the button; ii. a notch formed in the surface of the button between the first and second ends of the button; iii. a plunger aperture formed in the surface of the button between the first and second ends of the button, extending substantially transverse to the longitudinal axis of the button toward the central axis of the button and connecting with the substantially longitudinal locking aperture; iv. a plunger channel formed in the surface of the button between the first and second ends thereof, and connected to the plunger aperture; B. a detent plunger; C. a spring positioned to bias the detent plunger towards the lock button and into a position where the detent plunger interacts with the plunger aperture and plunger channel; and D. a key adapted for insertion into the female receiving end of the locking aperture of the button, wherein the key is adapted to interact with the plunger aperture when inserted into the female receiving end; and wherein the firing pin has a notch formed therein and adapted to interact with the notch of the lock button.
