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 has a base section and a stapling unit. The stapling unit is pivotally attached to the base section, and the base section is pivotally attached to a baseplate. In an initial position, the base section is fixed relative to the baseplate through a releasable locking mechanism connected to the baseplate and a base section. The base section has pivoting bending arms in an area underneath a support surface for a workpiece to be stapled. When a driver has driven a staple into the workpiece to a position in which the crown of the staple is in contact with the workpiece, the locking mechanism is released, and the base section pivots and is tilted against the baseplate, causing the bending arms to pivot so that the legs of the staple are bent into a position against the workpiece. A cutting pad disposed in an area between the bending arms interacts with the bending arms to cut off excess length of the staple legs.

Abstract: The stapling apparatus of the present invention comprises a base member and a magazine member for accommodating a set of staples, each member having a first end and a second end, and the two members being pivotably connected to each other at the first ends. The stapling apparatus further comprises a striking plate for individually dispensing the staples upon actuation by a striker spring, and a triggering mechanism for triggering the actuation of the striker spring. In particular, the triggering mechanism comprises a triggering lever arranged such that the triggering lever triggers the actuation of the striker spring when the second ends of the two members are moved toward each other.

Abstract: An anti-jamming design for a stapler track provides reduced force to shear a staple from a rack of staples. In stapling, a front staple must be separated from a rack of staples to eject the staple out. Conventional staplers shear the glue that holds the staples together all at once, so the peak force to separate the staple is high. In the present invention the glue that holds staples together in a rack is sheared by a peeling action. Locally progressing sections of glue are peeled as the front staple is sheared from the adjacent second staple. According to one embodiment of the invention progressive shearing is provided by an asymmetric track front end, whereby the front staples are fully supported on one side only so that the staple rack twists as the striker slowly presses down. The striker contacts the supported, higher, side of the staple first and the staple begins to shear from this higher side.

Abstract: A forward acting stapler includes a unique linkage for driving a firing lever. The linkage includes two links that are each connected to the trigger lever by a roller. The roller is movable within a spot in the trigger lever. As the handle is driven, the two links cause the triggering level to pivot. As the trigger lever pivots it lifts a plunger against a spring force. At some point, the trigger portion releases the plunger allowing the plunger to be returned by the spring force by a staple.

Abstract: A desktop stapler includes an automatic opening staple track whereby when the stapler is opened by pivoting the body about the base, the track is de-latched by ribs of the base, and the track slides out from a chamber within the body.

The stapler also features a striker bottom edge that is shaped to follow the curved shape of the anvil so that the striker may enter the anvil recess without impacting the anvil. A staple chamber in the stapler has staple exit ribs that allow only one staple at a time to be ejected from the staple chamber.

Abstract: The present invention provides for the safe and effective installation of staples. The device has a hollow body at its upper end, a cap plate with an opening attached to the upper end of the body, and a driver shaft mounted to slide within the cap plate. A block is secured within the body at the lower end of the body remote from the cap plate. The block has two channels and a striker slides through the channels. An indentation is located in the lower end of the block to hold the arch of a staple. A driver plate slides within the body and is secured to the driver shaft on one side and to both strikers on the opposite side. A driver spring and a pair of striker springs surround the driver shaft and strikers, respectively. The channels guide the strikers while the indentation positions the staple. This causes the strikers to strike the brads of the staple simultaneously, without damaging either the staple or the brads and, most importantly, the wiring or cabling the staple secures.
