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.
