Abstract

A stapler includes a base member, a magazine for receiving a plurality of staples, and a drive member including a driver blade movable relative to the magazine for ejecting staples from the magazine one at a time. The stapler further includes an input member pivotally coupled to the drive member. The input member is configured to receive an input force and transmit the input force to the drive member for driving movement of the drive member relative to the magazine. One of the drive member and the input member pivots about a pivot axis that moves relative to the base member along an arcuate path.

Claims (33)

1. A stapler comprising:

a base member;

a magazine for receiving a plurality of staples;

a drive member including a driver blade movable relative to the magazine for ejecting staples from the magazine one at a time;

an input member pivotally coupled to the drive member, the input member being configured to receive an input force and transmit the input force to the drive member for driving movement of the drive member relative to the magazine; and

means for pivoting one of the drive member and the input member about a pivot axis such that the pivot axis moves relative to the base member along an arcuate path.

2. The stapler of claim 1 , wherein the input member has a fixed pivot on the base member, and said means is provided between the base member and the drive member.

3. The stapler of claim 1 , wherein the drive member has a fixed pivot on the base member, and said means is provided between the base member and the input member.

4. The stapler of claim 1 , wherein said means includes an auxiliary member having a fixed pivot on the base member, movement of the auxiliary member about the fixed pivot defining the arcuate path.

5. The stapler of claim 1 , wherein said means includes an arcuate slot and a pin arranged in the arcuate slot.

6. The stapler of claim 5 , wherein the arcuate slot is formed in the base member.

7. A stapler comprising:

a base member;

a magazine for receiving a plurality of staples;

a drive member including a driver blade movable relative to the magazine for ejecting staples from the magazine one at a time;

an input member pivotally coupled to the drive member, the input member being configured to receive an input force and transmit the input force to the drive member for driving movement of the drive member relative to the magazine; and

an auxiliary member pivotally coupled to the base member and to one of the drive member and the input member, the other of the drive member and the input member being pivotally coupled to the base member.

8. The stapler of claim 7 , wherein the auxiliary member is pivotally coupled to the drive member.

9. The stapler of claim 8 , wherein the auxiliary member has a fixed pivot on the base member, the auxiliary member extending from the fixed pivot generally towards the location where the input member is pivotally coupled to the base member.

10. The stapler of claim 9 , wherein the input member is pivotally coupled to the base member adjacent a rear end of the stapler.

11. The stapler of claim 7 , wherein the auxiliary member is pivotally coupled to the input member.

12. The stapler of claim 11 , wherein the stapler includes a forward end and a rear end, a paper insertion opening of the stapler facing the forward end.

13. The stapler of claim 12 , wherein the auxiliary member has a fixed pivot on the base member, the auxiliary member extending from the fixed pivot generally towards the forward end of the stapler.

14. The stapler of claim 13 , wherein the fixed pivot of the auxiliary member is positioned forward of a fixed pivot of the drive member on the base member.

15. The stapler of claim 13 , wherein the fixed pivot of the auxiliary member is positioned rearward of a fixed pivot of the drive member on the base member.

16. The stapler of claim 13 , wherein the auxiliary member is positioned adjacent the rear end of the stapler.

17. The stapler of claim 12 , wherein the auxiliary member has a fixed pivot on the base member, the auxiliary member extending from the fixed pivot generally towards the rear end of the stapler.

18. The stapler of claim 17 , wherein the auxiliary member is positioned adjacent the rear end of the stapler.

19. A paper tool comprising:

a base member;

a drive member;

an input member pivotally coupled to the drive member; and

means for pivoting the drive member about a pivot axis such that the pivot axis moves relative to the base member along an arcuate path.
