Abstract

Various embodiments of the present disclosure provide a battery-powered stapling tool. In one embodiment, the stapling tool includes a drive wheel, a cam drivable by the drive wheel in a first rotational direction from a first position to a second position and back to the first position to carry out a staple-driving process, a motor operably connected to the drive wheel to drive the drive wheel, a lifting element defining a slide in which the cam is received, and an ejector connected to the lifting element and drivable by the lifting element between an ejector home position and an ejector ejection position. The slide has first and second slide segments that are transverse to one another. The lifting element is movable between a lifting-element home position and a lifting-element ejection position.

First claim

The invention claimed is:

1. A stapling device comprising:
a drive wheel;
a cam drivable by the drive wheel in a first rotational direction from a first position to a second position and back to the first position to carry out a staple-driving process;
a motor operably connected to the drive wheel to drive the drive wheel;
a lifting element defining a slide in which the cam is received, the slide having first and second slide segments that are transverse to one another, wherein the lifting element is movable between a lifting-element home position and a lifting-element ejection position; and
an ejector connected to the lifting element and drivable by the lifting element between an ejector home position and an ejector ejection position, wherein the ejector is in the ejector home position when the lifting element is in the lifting-element home position, wherein the ejector is in the ejector ejection position when the lifting element is in the lifting-element ejection position,
wherein the first and second slide segments are oriented such that:
the cam is positioned in the second slide segment as the cam rotates in the first rotational direction from the first position to the second position and drives the lifting element and the ejector to move from their lifting-element and ejector home positions toward their lifting-element and ejector ejection positions, and
the cam moves from the second slide segment into the first slide segment as the cam rotates in the first rotational direction from the second position back to the first position and drives the lifting element and the ejector to finish moving to their lifting-element and ejector ejection positions and then to move back to their lifting-element and ejector home positions,

wherein the lifting element and the ejector are movable between their respective lifting-element and ejector home and ejection positions along a movement axis, and wherein an orientation of the first and second slide segments relative to the movement axis does not change as the lifting element moves between the lifting-element home and ejection positions.

2. The stapling device of claim 1 , wherein the first position is an upper-dead-center position, wherein the second position is a lower-dead-center position.

3. The stapling device of claim 1 , wherein the cam is positioned solely in the second slide segment as the cam rotates in the first rotational direction from the first position to the second position.

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

5. The stapling device of claim 4 , wherein the lifting element is operably connected to the clinchers such that movement of the lifting element between the lifting-element home and ejection positions causes the clinchers to move between their home and bending positions.

6. The stapling device of claim 5 , wherein the first position is an upper-dead-center position, wherein the second position is a lower-dead-center position.

7. The stapling device of claim 1 , wherein the first slide segment, the second slide segment, and the movement axis are transverse to one another.

8. The stapling device of claim 7 , wherein the second slide segment is substantially perpendicular to the movement axis, and wherein the first and second slide segments form an oblique angle.
