Embodiment Construction

[0050] figure 1 An exemplary desktop stapler 100 is shown including a stapler body supporting operating components with an exemplary frame 10 , 40 of a flat clinching anvil assembly fitted to a stapler base 120 . Other anvil frames and components as described or contemplated by the present invention may be assembled to base 120, however Figure 2 to Figure 16 The components of are used in the present context of stapler 100 for simplicity. The stapler body is capable of firing the staple fastener toward the base during an operating cycle of the stapler. During such an operating cycle (not shown), staples fed from a rack advancing on guide rails are ejected abruptly from the stapler body by impact action. The stapler operating cycle may be of the type disclosed, for example, in U.S. Patent No. 6,918,525 (Marks), entitled "(Spring Energized Desktop Stapler)," the contents of which are incorporated by reference. The space between the underside of the stapler and the base is cap...

Abstract

A flat clinch assembly fits upon or within a base of a stapling device. The assembly preferably includes a slot with extended resiliently biased arms or toggles, where a rest position has the arms at or near a level of a working surface. An ejecting staple deflects and energizes the arms to cause the arms to rotate and create a clearance recess whereby points of the staple legs slide inward along the anvil. A restorative bias acting on the arms causes the arms to rebound to a rest position and to bend the legs upward. The legs thereby are normally pressed flat against the back sheet of a paper stack at the working surface. The arms or toggles are lightweight whereby the inertia of a fast moving staple moves the arms or toggles.

Description

[0001] Cross References to Related Applications [0002] This non-provisional patent application claims the benefit of priority to US Provisional Patent Application No. 61 / 755,894, filed January 23, 2013, the contents of which are incorporated by reference. technical field [0003] This invention relates to improvements in bookbinding. More precisely, the invention relates to a mechanism for flat clamping of the legs of a staple. Background technique [0004] In desktop or other office and related types of staplers, the anvil operates beneath a stack of paper to bend the staple legs behind the paper. These clamps bind the paper together. A typical anvil is made of hard steel plate and includes two adjacent curved recesses. During stapling, the staple legs enter the outer portion of the recess and slide within said recess to form a circular or annular clinch. The legs are formed at the same time the staples are ejected from the stapler. This system is simple and generall...
