Abstract: A spring energized stapler includes a “high start” design wherein a striker has a rest position above the staple track. A handle is pressed to energize a power spring while the striker remains stationary. At a predetermined position of the handle, the striker is released to eject a staple. A subassembly of a cage and the power spring provides a preload to the power spring in the rest position. The subassembly is separately movable from the handle to allow a handle pressing end to move farther than the striker's distance of travel. The handle includes a movable pivot location to enable enhanced motion of the handle pressing end. Alternatively, an optional lever links the striker to the power spring to provide leverage upon the power spring. A release latch may be mounted in front of the striker to be engaged by the lever or the handle.

Abstract: A stapler device and a method of stapling an article. The stapler has a striker and a spring for driving the striker to apply a staple. During the stapling cycle, the striker and spring are cocked and loaded prior to being release to apply the staple.

Once the stapling cycle is continued, the cocked and loaded striker and spring are released to apply a staple. The device is also selectively capable of a second mode of operation wherein the stapling cycle is not interrupted.
