ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates generally to safety mechanisms for use in firearms and more particularly to a lockable safety mechanism able to prevent firing when in the safety mode and to prevent unauthorized use of the firearm when in the locked mode. There is a continued need for a device that is easy to use yet effectively deters unauthorized use of the firearm, and a particular need for a device that operates in a manner that is similar to previous safety mechanisms, yet also provides a locking function.
SUMMARY OF THE INVENTION
The present invention provides safety mechanisms that also provide a locking function, thus satisfying the need for a means of deterring unauthorized use of the firearm.
Specifically, one embodiment of the present invention provides a safety mechanism for use in a firearm comprising:
A. a safety button having a first end and a second end and comprising:
i. a locking aperture formed along a substantially longitudinal axis of the button comprising a female receiving end formed in the first end of the button;
ii. a receiving 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, the plunger aperture being operatively connected to:
iv. a substantially transverse plunger channel, operatively connected to:
v. a first portion of a substantially longitudinal plunger channel, the substantially longitudinal plunger channel comprising the first portion and an operatively connected second portion, each portion being separated by a detent surface;
B. a detent plunger;
C. means to bias the detent plunger towards the safety button and into a position where the detent plunger interacts with one of the plunger aperture, the substantially longitudinal plunger channel and the substantially transverse plunger channel; and
D. locking means adapted for insertion into the female receiving end of the locking aperture of the safety button, wherein the locking means is adapted to interact with the plunger aperture when inserted into the female receiving end.
In another embodiment of the present invention there is provided a safety mechanism for use in a firearm comprising:
A. a safety button having a first end and a second end and comprising:
i. a locking aperture formed along a substantially longitudinal axis of the button comprising a female receiving end formed in the first end of the button;
ii. a receiving 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, the plunger aperture being operatively connected to:
iv. a plunger channel; and
B. a detent plunger;
C. a spring positioned to bias the detent plunger towards the safety button and into a position where the detent plunger interacts with one of the plunger aperture, substantially longitudinal plunger channel and substantially transverse plunger channel; and
D. a key adapted for insertion into the female receiving end of the locking aperture of the safety button, wherein the key is adapted to interact with the plunger aperture when inserted into the female receiving end.
In a further embodiment of the present invention there is provided a safety mechanism for use in a firearm comprising:
a safety button transversely movable between a safe and a fire position and rotatable between the safe position and a safe and locked position;
a detent plunger adapted to lock the safety button in the safe and locked position and to prevent further movement of the safety button; and
a key adapted to be received through a key hole formed in the safety button, the key being adapted to engage the detent plunger for moving said detent plunger out of engagement with said safety button to enable rotation of the safety button from the safe and locked position to the safe position.
Yet another embodiment of the invention provides a safety mechanism for a firearm comprising:
a safety button transversely movable between a safe to restrict operation of the firearm and a fire position and rotatable between the safe position and the safe and locked position, and including first and second ends and a locking aperture formed through the safety button, and
a detent plunger adapted to engage the safety button as the safety button is moved to its safe and locked position to restrict further rotation of the safety button and maintain the safety button in its safe and locked position to prevent rotation of the safety button from the safe and locked position to the safe position.
