Lockable firearm safety device
View Patent ↗A lockable safety device for use with a firearm. The device comprises a clamp or bracket that is engageable with a locking bar. When the clamp and locking bar are engaged with a firearm, access to, and use of, the firearm is restricted. The clamp can comprise a third arm projecting therefrom to prevent complete cycling of the firearm action.
1. A safety device for a firearm having a breech block, comprising:
a clamp including a base having first and second end portions, a first arm mounted to and projecting from the first end portion, a second arm mounted to and projecting from the second end portion;
a clamp closure that is manually separable from the clamp and having first and second ends, the clamp closure first end selectively engageable in a sequential fashion with one of the first or second arms and then with the other of the first or second arms; and
wherein a portion of the base interferes with full cycling of the breech block when the safety device is engaged to the firearm so that the firearm cannot be discharged.
2. The device of claim 1 , wherein the base portion comprises a third arm mounted to and projecting from the base.
3. The device of claim 1 , wherein the base portion comprises a third arm rigidly mounted to the base between the first and second arms, the third arm projecting from the base in a direction generally similar to the first and second arms, wherein the third arm is disposed within a loading port or an ejection port when the clamp is engaged to the firearm.
4. The device of claim 1 , wherein the base defines an aperture therein having an edge and the base portion comprises an arm attached to the base at the edge.
5. The device of claim 1 , wherein the base portion comprises an arm bent from material of the base to form a corresponding aperture in the base.
6. The device of claim 1 , wherein the first and second arms are rigid and the clamp defines a C shape.
7. The device of claim 1 , wherein the clamp is mounted to a surface and the firearm is immobilized adjacent the surface when engaged by the clamp and clamp closure.
8. The device of claim 1 , wherein the base defines a base plane and the base portion defines a stopper plane generally orthogonal to the base plane.
9. The device of claim 1 , wherein the base defines a base plane and the base portion defines a base portion plane generally coextensive with the base plane.
10. The device of claim 1 , wherein the firearm defines a firearm longitudinal axis and the base portion defines a base portion plane that is generally orthogonal to the firearm longitudinal axis.
11. A device for preventing unauthorized use of a firearm, comprising:
a clamp, including:
a base defining a base plane and having first and second end portions,
a first arm rigidly mounted to the base toward the first end portion and projecting orthogonally from the base plane, the first arm defining a longitudinal centerline parallel to the base plane and having a free end,
a second arm rigidly mounted to the base toward the second end portion and projecting orthogonally from the base plane, the second arm defining a longitudinal centerline parallel to the base plane and having a free end,
a base portion disposed on the base to physically prevent full cycling of the breech block when the clamp is engaged to the firearm, and
a locking bar having first and second ends, the locking bar first end selectively engageable in a sequential fashion with either one of the first or second arm projecting ends and then with the other of the first or second arm projecting ends.
12. The device of claim 11 , wherein the base and the base portion are coplanar.
13. The device of claim 11 , wherein the first and second arm projecting ends each define an aperture; the locking bar second end includes an expanded portion and the locking bar first end defines an aperture, and the locking bar first end is inserted sequentially through the first and second arm apertures to engage the clamp and the locking bar expanded portion prevents movement of the locking bar second end through the first arm aperture.
14. The device of claim 11 , wherein the firearm comprises a break open firearm including a barrel assembly having a chamber end; the breech block comprises a breech face and the base portion is positionable intermediate the breech block and chamber end of the barrel base.
15. A portable safety device for selective attachment to a firearm having a breech block and a chamber, comprising:
a clamp, including a base having opposing first and second end portions, a first arm mounted to the base at the first end portion and having an end projecting from the base, the first arm end defining an aperture, a second arm fixed to the base at the second end portion and having an end projecting from the base generally parallel with the first arm, the second arm defining an aperture;
a base portion disposed on the base and positionable within the firearm to physically prevent the breech block from dosing the chamber when the safety device is engaged with the firearm; and
a locking member manually removable from the clamp and comprising a small end defining a locking aperture and a large end sized to prevent passage through the first arm aperture, the locking member selectively engageable with the clamp by a sliding motion of the small end through the first arm aperture and subsequently a sliding motion of the small end through the second arm aperture so that the locking aperture protrudes from the second arm aperture, the clamp and engaged locking member encircling the receiver,
wherein the portable safety device and attached firearm can be readily carried by a user.
16. The safety device of claim 15 wherein the base portion is fixed to the clamp between the first arm end and the second arm end and projects in a direction generally similar to the arms.
17. The safety device of claim 15 wherein the locking member is rigid.
18. The safety device of claim 15 wherein the base portion is generally coplanar with the base.
19. The device of claim 11 , wherein the first arm longitudinal centerline and the second arm longitudinal centerline are offset from each other.
20. The device of claim 15 , wherein the firearm comprises a break open firearm; and the base portion is positionable intermediate the breech block and the chamber.
