Stored energy stapler

1. A stored energy stapler comprising:

a base portion;

a first lever pivotally coupled to the base portion, the first lever having a front end and a back end;

a second lever pivotally coupled to the base portion about a pivot point, the second lever having a front end and a back end, and a striker element at the front end for driving a staple out of the stapler; and

a torsion spring coupled to both the first lever and the second lever that biases the back ends of the first and second levers apart from one another;

wherein the pivot point is disposed between the striker element and the torsion spring.

2. The stored energy stapler of claim 1 , further comprising a latch mechanism coupled to the second lever to selectively prevent rotation of the second lever about the pivot point.

3. The stored energy stapler of claim 2 , wherein the torsion spring is a first biasing member, and wherein the latch mechanism is rotationally biased by a second biasing member into a secured engagement with the second lever to prevent the striker element from engaging a staple.

4. The stored energy stapler of claim 3 , wherein the torsion spring is a first torsion spring, and wherein the second biasing member is a second torsion spring.

5. The stored energy stapler of claim 4 , wherein the second torsion spring is wrapped about a pin that extends through the second lever, the pin defining a rotational axis about which the latch mechanism rotates.

6. The stored energy stapler of claim 3 , wherein the torsion spring is sized and configured to store energy when the front end of the first lever is pressed toward the base portion, and wherein the torsion spring is configured to release the stored energy when the latch mechanism is rotated out of the secured engagement with the second lever.

7. The stored energy stapler of claim 3 , wherein the latch mechanism includes a cam surface and a notch.

8. The stored energy stapler of claim 7 , wherein the first lever includes a first latch pin disposed on the back end of the first lever that is sized and configured to engage the cam surface and rotate the latch mechanism out of the secured engagement.

9. The stored energy stapler of claim 8 , wherein the second lever includes a second latch pin disposed on the back end of the second lever that is sized and configured to be received in the notch during the secured engagement.

10. The stored energy stapler of claim 9 , wherein the torsion spring is wrapped about the second latch pin, and includes two arms that extend rearwardly toward the back end of the second lever.

11. The stored energy stapler of claim 1 , wherein the torsion spring includes a first arm that engages the second lever, and a second arm that engages a latch pin on the first lever.

12. The stored energy stapler of claim 11 , wherein the first arm and second arm of the torsion spring bias the back ends of the first and second levers apart from one another.

13. The stored energy stapler of claim 1 , wherein the pivot point is a second pivot point, and wherein the first lever is pivotally coupled to the base portion about a first pivot point disposed between the second pivot point and the torsion spring.

14. The stored energy stapler of claim 1 , further comprising a magazine pivotally coupled to the second lever about the pivot point, the magazine sized and configured to hold staples, the magazine including a first component pivotally coupled to the second lever, a second component pivotally coupled to the first component, and a third component slidably coupled to the first component and releasably coupled to the second component.

15. The stored energy stapler of claim 14 , wherein the stapler includes an activation member sized and configured to engage the second component to release the third component from the second component.

16. A stored energy stapler comprising:

a base portion sized and configured to rest on a flat surface;

a top lever pivotally coupled to the base portion about a first pivot point, the top lever including a first latch pin at a back end of the top lever;

a striker lever pivotally coupled to the base portion about a second pivot point, the striker lever having a striker element at a front end of the striker lever and a second latch pin at a back end of the striker lever;

a staple magazine pivotally coupled to the striker lever about the second pivot point, the staple magazine sized and configured to hold a plurality of staples to be driven out of the stapler by the striker element;

a torsion spring coupled to both the back end of the striker lever and the back end of the top lever that biases the back ends of the striker lever and the top lever apart from one another, the torsion spring including a first arm that engages the striker lever and a second arm that engages the first latch pin at the back of the top lever; and

a latch mechanism pivotally coupled to the striker lever for rotation between a secured position and a released position, the latch mechanism including a cam surface sized and configured to be engaged by the first latch pin to move the latch mechanism into the released position, and a notch for holding and retaining the second latch pin when the latch mechanism is in the secured position.

17. The stored energy stapler of claim 16 , wherein the torsion spring is wrapped about the second latch pin.

18. The stored energy stapler of claim 16 , wherein the torsion spring includes two arms that extend rearwardly toward the back end of the striker lever.

19. The stored energy stapler of claim 18 , wherein the two arms include a first arm that engages the striker lever and a second arm that engages the first latch pin.

20. The stored energy stapler of claim 16 , wherein the first pivot point is disposed between the second pivot point and the torsion spring.
