US Patent:

6739492, May 25, 2004

Filed:

Jun 11, 1999

Appl. No.:

09/590283

Inventors:

David P. Adams - Barrington IL
Valentin Fridmanovich - Forest Hills NY
Kenneth John Bargo - Chicago IL

Assignee:

Acco Brands, Inc. - Lincolnshire IL

International Classification:

B25C 504

US Classification:

227 82, 227 88, 227109

Abstract:

A staple forming mechanism having at least first and second configurations. The staple forming mechanism including a bend surface having a first surface width in the first configuration and a second surface width in the second configuration for forming staples having first and second crown sizes, respectively. The forming mechanism also includes at least two side portions spaced apart by a first former width in the first configuration and by a second former width in the second configuration. The side portions cooperate with the bend surface to form the staples. A stapler includes the forming mechanism and a driver including a driving surface having a first driver width in the first configuration and a second driver width in the second configuration for driving the staples of the first and second crown sizes into a stack of papers. A clinching assembly includes at least one clinching member that is movable along a clinching path to engage a leg of the staple at substantially the same angle regardless of whether the staple is of the first or second crown size.

ACCO Brands, Inc. - Lincolnshire IL

International Classification:

B25C 515

US Classification:

227 5, 227131, 227155

Abstract:

A stapler is provided with a frame and a head assembly pivotally disposed in the frame between a first open position and a second clamped position. The head assembly contains all of the operative elements of the stapler necessary to carry out a stapling operation and is biased toward the open position by a biasing member disposed between the head assembly and the frame. These operative elements include a staple driving mechanism, a motor fixed to the head assembly, a cam member connected to the motor and rotated thereby. The cam member contains at least three surfaces that simultaneously form and drive staples, pivot the head assembly in the frame, and actuate a microswitch controlling power to the motor. The cam member cooperates with a first bar disposed between the frame and a spring assembly to permit the first bar to flex to accommodate varying thicknesses or amounts of paper to be stapled. Fewer operative parts are need because the motor and cam member surfaces all rotate around parallel axes that are perpendicular to the axes about which the head assembly pivots.
