Abstract

A manually operated staple gun includes a frame, a staple magazine, and a user-actuated unit. The user-actuated unit is mounted in the frame to switch between a first condition wherein the magazine is configured to guide staples of a first width along a guide axis into a ready position to be driven into a work piece and a second condition wherein the magazine is configured to guide staples of a second width along the guide axis into the ready position to be driven into a work piece.

First claim

What is claimed is:

1. A manually operated staple gun configured to carry a collation of staples and sequentially drive each of the staples of the collation in response to user actuation of the staple gun, the staple gun capable of utilizing staples having different widths, the widths defined by a pair of spaced legs on each staple, the staple gun comprising:
a frame;
a staple magazine in the frame selectively configurable to receive a first collation of staples having a first width and a second collation of staples having a second width, the second width being greater than the first width;
a user-actuated staple guide having a first pair of longitudinally extending guide surfaces to guide staples of the first width along a guide axis into a ready position to be driven into a work piece, the staple guide being mounted in the frame to move between a guiding position wherein the guide surfaces guide staples of the first width along the guide axis and a stowed position wherein the guide surfaces do not guide staple along the guide axis; and
a second pair of longitudinally extending guide surfaces to guide staples of the second width along the guide axis into the ready position to be driven into a work piece with the staple guide in the stowed position.

2. The staple gun of claim 1 wherein the staple guide is u-shaped with a pair of legs defining the guide surfaces and a bridge joining the legs.

3. The staple gun of claim 2 wherein each of the legs is a leaf-spring that can be deflected by a user from the guiding position to the stowed position.

4. The staple gun of claim 2 wherein the staple guide is pivot mounted to the frame at the bridge and the legs pivot between the guiding and stowed positions.

5. The staple gun of claim 4 wherein the legs and the bridge are defined by a continuous length of cylindrical shaped material.

6. The staple gun of claim 5 wherein the continuous length of material is a metallic wire that has been permanently deformed to define the legs and the bridge.

7. The staple gun of claim 2 further comprising a user-actuated slide mounted to the frame to move between first and second positions, and wherein the staple guide further includes a foot extending from one of the legs and operably engaged with the slide to transmit an actuating force from the slide to the staple guide to actuate the staple guide between the guiding and stowed positions as the slide is moved between the first and second positions.

8. The staple gun of claim 7 wherein the slide is mounted to the frame to translate between the first and second positions and the staple gun further includes a spring-biased detent that engages the slide in the first position to retain the slide in the first position.

9. The staple gun of claim 1 wherein the staple guide is mounted to the frame to pivot between the guiding and stowed positions.

10. The staple gun of claim 9 further comprising a user-actuated slide mounted to the frame to move between first and second positions, the slide operably engaged with the staple guide to transmit an actuating force to pivot the staple guide between the guiding and stowed positions as the slide is moved between the first and second positions.

11. The staple gun of claim 10 wherein the slide is mounted to the frame to translate between the first and second positions.

12. The staple gun of claim 1 further comprising a user-actuated slide mounted to the frame to move between first and second positions, the slide operably engaged with the staple guide to transmit an actuating force to move the staple guide between the guiding and stowed positions as the slide is moved between the first and second positions.

13. The staple gun of claim 12 wherein the slide is mounted to the frame to translate between the first and second positions.

14. The staple gun of claim 1 wherein the second pair of guide surfaces extend parallel to the guide axis and are defined by the frame.

15. The staple gun of claim 1 wherein the first and second pairs of guide surfaces extend parallel to the guide axis.
