Abstract:
A hole punch (10) includes a base (12) and a lever system (20) to actuate a punch (18, 98). The lever system includes a first lever (22) having an end pivotally connected to the first end (14) of the base and a second lever (24) having an end pivotally connected to the second end of the base (16). Actuation of a free end (25) of the second lever causes the first lever to move. In one embodiment, a lock (140) is operatively coupled to the lever system and engages the first and second levers to hold the levers in a stowed position. In another embodiment, the hole punch includes a third lever (32) having a first end operatively coupled to the first lever and a second end operatively coupled to the second lever.
Abstract:

Abstract:
The present invention relates to a punch (1) for punching a workpiece. In particular, the invention relates to a punch including a base (6) 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 (3) 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.
