Magazine for firearms
A magazine is provided for a firearm. The magazine comprises a locking mechanism. The locking mechanism has a user interface adapted to enable a user to select between a locked condition and an unlocked condition. The locking mechanism has a rotor movable between a first rotational position when the locking mechanism is in the locked condition and a second rotational position when the locking mechanism is in the unlocked condition. The magazine comprises an elongated shaft connected to the rotor. The magazine comprises a block element connected to the elongated shaft. The block element is adapted to move between a first position when the locking mechanism is in the locked condition in which at least one of firearm operation and magazine extraction are prevented, and a second position when the locking mechanism is in the unlocked condition in which firearm operation and magazine extraction are enabled.
1. A magazine for a firearm comprising:
an elongated tubular body defining an ammunition compartment and having an upper end defining an ammunition exit aperture and a lower end opposed to the upper end;
a locking mechanism connected to the lower end of the elongated tubular body and having a locked condition and an unlocked condition;
the locking mechanism having a user interface adapted to enable a user to select between the locked condition and the unlocked condition;
the locking mechanism having a rotor movable between a first rotational position when the locking mechanism is in the locked condition and a second rotational position when the locking mechanism is in the unlocked condition, the second rotational position different than the first rotational position;
an elongated shaft having a lower end connected to the rotor whereby the rotor rotates the elongated shaft, and an upper end opposed to the lower end; and
a block element connected proximate to the upper end of the elongated shaft, the block element adapted to move between a first position when the locking mechanism is in the locked condition in which at least one of firearm operation and magazine extraction are prevented, and a second position when the locking mechanism is in the unlocked condition in which firearm operation and magazine extraction are enabled.
2. The magazine according to claim 1 , wherein the elongated shaft is a straight element.
3. The magazine according to claim 1 , wherein the elongated shaft is a cylindrical element.
4. The magazine according to claim 1 , wherein the elongated shaft has a circular cross section.
5. The magazine according to claim 1 , wherein the upper end of the elongated shaft is proximate the upper end of the elongated tubular body.
6. The magazine according to claim 1 , wherein the upper end of the elongated shaft is closer to the upper end of the elongated tubular body than to the lower end of the elongated tubular body.
7. The magazine according to claim 1 , wherein the elongated tubular body defines a shaft passage receiving the elongated shaft.
8. The magazine according to claim 1 , wherein the elongated tubular body has opposed sidewalls, a front wall, and a rear wall, and wherein the elongated shaft is proximate to one of the opposed sidewalls and to the front wall.
9. The magazine according to claim 1 , wherein the elongated tubular body has opposed sidewalls, a front wall, and a rear wall, and wherein the elongated shaft is proximate to the rear wall.
10. The magazine according to claim 1 , wherein the elongated tubular body has an exterior profile adapted to be closely received in a firearm magazine well, and wherein the block element is within the exterior profile to enable extraction of the magazine when in the second position and protrudes from the exterior profile to prevent extraction of the magazine when in the first position.
11. The magazine according to claim 1 , wherein the block element is an elongated element extending away from the elongated shaft.
12. The magazine according to claim 1 , wherein the block element is a planar element having a major surface flush with an external surface of the elongated tubular body when the block element is in the second position.
13. The magazine according to claim 1 , wherein the block element extends laterally from the elongated shaft.
14. The magazine according to claim 1 , wherein the block element extends radially from the elongated shaft.
15. The magazine according to claim 1 , wherein the block element extends transversely from the elongated shaft.
16. The magazine according to claim 1 , wherein the block element extends perpendicularly from the elongated shaft.
17. The magazine according to claim 1 , wherein the block element defines a block passage receiving the elongated shaft.
18. The magazine according to claim 1 , wherein the firearm includes a trigger element movable between a rest position and a discharge position, and wherein when the block element is in the first position the block element is adapted to contact the trigger element to prevent motion of the trigger element.
19. The magazine according to claim 1 , further comprising a status indicator movable between a first position and a second position based on whether the locking mechanism is in the locked condition or the unlocked condition.
20. The magazine according to claim 19 , wherein the status indicator is adapted to provide a tactile indication of its condition.
