Abstract

Various embodiments of the present disclosure provide a battery-powered stapling tool. A stapling tool includes a drive wheel, a slide comprising a first slide segment and a second slide segment, and a drive shaft receivable by the slide, wherein the drive shaft is coupled to and drivable by the drive wheel such that rotation of the drive wheel in a first rotational direction moves the drive shaft from the first slide segment to the second slide segment back to the first slide segment. The stapling tool further includes a lifting element, wherein the lifting element defines the slide and is drivable by the drive shaft, and an ejector coupled to the lifting element and drivable by the drive shaft.

First claim

The invention claimed is:

1. A stapling device comprising:
a drive wheel;
a slide comprising a first slide segment and a second slide segment, wherein the first slide segment and the second slide segment form an oblique angle;
a drive shaft receivable by the slide, wherein the drive shaft is coupled to and drivable by the drive wheel such that rotation of the drive wheel in a first rotational direction moves the drive shaft from the first slide segment to the second slide segment back to the first slide segment;
a lifting element, wherein the lifting element defines the slide and is drivable by the drive shaft; and
an ejector coupled to the lifting element and drivable by the drive shaft, wherein movement of the drive shaft from the first slide segment to the second slide segment moves the ejector and the lifting element along an axis from a home position to an ejection position, and wherein movement of the drive shaft from the second slide segment back to the first slide segment moves the ejector and the lifting element along the axis from the ejection position back to the home position.

2. The stapling device of claim 1 , further comprising a pair of clinchers each movable between respective home positions and respective bending positions and configured to bend a leg of a staple.

3. The stapling device of claim 2 , further comprising a guide element coupled to the ejector and rotatably coupled to the pair of clinchers.

4. The stapling device of claim 2 , wherein the lifting element is operably connected to the clinchers such that movement of the lifting element between the home position and the ejection position moves the clinchers between their respective bending positions and their respective bending positions.

5. The stapling device of claim 1 , further comprising a motor configured to drive the drive wheel in the first rotational direction.

6. The stapling device of claim 1 , wherein the drive shaft further comprises a cam coupled to the drive shaft, wherein movement of the drive shaft from the first slide segment to the second slide segment rotates the cam in a first rotational direction.

7. The stapling device of claim 6 , wherein movement of the drive shaft from the second slide segment back to the first slide segment rotates the cam in a second rotational direction, opposite the first rotational direction.

8. The stapling device of claim 1 , wherein the second slide segment is perpendicular to a movement axis, and the first slide element forms an oblique angle relative to the second slide segment.

9. The stapling device of claim 8 , wherein the ejector moves along to the movement axis when moving between the home position and the ejection position.

10. The stapling device of claim 8 , wherein the orientation of the first slide element and the second slide element relative to the movement axis does not change as the ejector moves between the home position and the ejection position.

11. The stapling device of claim 1 , further comprising a cam coupled to the drive shaft, wherein movement of the drive shaft from the first slide segment to the second slide segment rotates the cam in a first rotational direction, and wherein movement of the drive shaft from the second slide segment back to the first slide segment rotates the cam in a second rotational direction, opposite the first rotational direction.

12. A stapling device comprising:
a drive wheel;
a lifting element defining a slide, the slide comprising a first slide segment and a second slide segment, wherein the first slide segment and the second slide segment form an oblique angle;
a drive shaft receivable by the slide, wherein the drive shaft is coupled to and drivable by the drive wheel such that rotation of the drive wheel in a first rotational direction moves the drive shaft from the first slide segment to the second slide segment back to the first slide segment;
a lifting element, wherein the lifting element defines the slide and is drivable by the drive shaft; and
an ejector coupled to the lifting element and drivable by the drive shaft, wherein movement of the drive shaft from the first slide segment to the second slide segment moves the ejector and the lifting element along an axis from a home position to an ejection position, and wherein movement of the drive shaft from the second slide segment back to the first slide segment moves the ejector and the lifting element along the axis from the ejection position back to the home position.

13. The stapling device of claim 12 , further comprising a pair of clinchers each movable between respective home positions and respective bending positions and configured to bend a leg of a staple.

14. The stapling device of claim 13 , further comprising a guide element coupled to the ejector and rotatably coupled to the pair of clinchers.

15. The stapling device of claim 13 , wherein the lifting element is operably connected to the clinchers such that movement of the lifting element between the home position and the ejection position moves the clinchers between their respective bending positions and their respective bending positions.

16. The stapling device of claim 12 , further comprising a motor configured to drive the drive wheel in the first rotational direction.
