Abstract: A stapler includes a base member, a magazine for receiving a plurality of staples, and a drive member including a driver blade movable relative to the magazine for ejecting staples from the magazine one at a time. The stapler further includes an input member pivotally coupled to the drive member. The input member is configured to receive an input force and transmit the input force to the drive member for driving movement of the drive member relative to the magazine. The stapler further includes means for pivoting one of the drive member and the input member about a pivot axis such that the pivot axis moves relative to the base member along an arcuate path.

Abstract: A punch includes punch pads that are easily and conveniently adjustable by a user. The punch includes a base and a punch head coupled to the base. The punch head includes a punch pin configured to move in a punching direction. An adjustable punch pad is mounted to the punch. The adjustable punch pad includes a receiving surface for receiving the punch pin. An actuator is coupled to at least one of the punch pads to move the punch pad.

Abstract: A paper tool includes a power transmission linkage. The linkage includes a base, a drive link, an input member, and at least three pivots connecting members of the linkage. At least one of the pivots provides for both rotational and translational movement between two members connected by the at least one pivot.

Abstract: A punch head includes a punch pin and a punch housing supporting the punch pin. The punch housing includes a slot for receiving one or more workpieces to be punched. The slot defines a stack height SH. The punch housing further includes first and second walls, at least one of the first and second walls defining a wall thickness T. Each of the first and second walls also includes an aperture for receiving a pivot pin coupling a punch pin actuation member to the punch housing. A ratio of the wall thickness T to the stack height SH is greater than 0.9.

Abstract: A stapler movable between a rest position and a stapling position and having a front end and a rear end. The stapler includes a base, a staple magazine coupled to the base and configured to hold staples, and a driver blade operable to drive staples out of the staple magazine during stapling operations. The stapler further includes an elastic member coupled to the driver blade and operable to move the driver blade during stapling operations. The elastic member utilizes potential energy to move the driver blade during stapling operations. The driver blade is positioned above the staple magazine when the stapler is in the rest position and the magazine is extendable from the front end of the stapler to allow a user to load staples in the magazine. The stapler is configured such that only the potential energy of the elastic member can operate the driver blade during stapling operations.

Abstract: A desktop stapler includes a base configured to rest on a support surface, a cover, and a magazine. The stapler further includes an elastic member, a driver blade, and a support member. The elastic member is positioned at least partially between the cover and magazine and stores energy applied to the cover as the cover is moved relative to the magazine. The driver blade is coupled to an end of the elastic member and is configured to push out staples from the magazine. The support member selectively engages the elastic member and energy is stored in the elastic member as the cover is moved relative to the magazine. The elastic member is engaged with a portion of the support member. Energy stored in the elastic member is released when the elastic member disengages from the portion of the support member, causing the driver blade to push out a staple.

Abstract: A punch for punching a workpiece. The punch includes a base and a workpiece support coupled to the base and arranged to support the workpiece in a substantially upright position. A punch member is coupled to the workpiece support and is movable between a ready position and a punch position. A lever arm is movable through an angle greater than or equal to about 60 degrees to move the punch member between the ready position and the punch position and a linkage interconnecting the lever arm and the punch member.

Abstract: A punch for punching a workpiece. In particular, the invention relates to a punch including a base to stably support the punch and a support member configured to accommodate and locate the workpiece in a punching position. The support member is preferably movably connected to the base and preferably includes at least one punch member configured and operably associated with the support portion to punch the workpiece in the punching position upon an actuation movement of the support member with respect to the base. Another embodiment of the present invention relates to a punch having a paper tray oriented at an angle with respect to the base to support a sufficient portion of a sheet of paper to prevent an unsupported portion from falling over and withdrawing from the support portion. In particular, the paper tray and punch mechanism are oriented to expel paper chips such that the chips are visible to an operator as they are punched.

Abstract: The present invention discloses a hand held stapler which can be used for joining sets of different numbers of paper sheets. The stapler has a stapling arm with a lever which extend past a pivot position by a length greater than the magazine of the stapler by an amount sufficient to provide a substantially increased leverage for driving staples during the stapling operation.

Abstract: A hand-operated punch with adjustable assembly punch units and a slipper to receive punched out discs in which the assembly units are adjustable from the bottom through an opening in the slipper. The punch includes a strengthening flap configuration and the assembly units slide but do not turn during adjustment.
