Abstract
A hole punch with a detached base includes a base supporting an anvil with a first magnetic element, and a punch assembly with a plunger extendable from the framework of the punch assembly. The punch assembly supports a second magnetic element positioned for magnetic coupling to the base to align the anvil with the plunger. The magnetic coupling feature eliminates throat depth limitations caused by the framework of mechanically coupled hole punches of the prior art and allows for hole placement at any desired location on any size of sheet.
Claims9
A hole punch with a detached base, comprising:
- a base supporting an anvil and a first magnetic element;
- and
- a punch assembly structurally independent of said base and including means for extending and retracting a plunger having a cutting edge on an impact end thereof, said punch assembly supporting a second magnetic element, said second magnetic element being positioned on said punch assembly for magnetically coupling said base to said punch assembly to align said anvil with said cutting edge.
A hole punch comprising:
- a base having an anvil and a first magnetic element;
- a framework supporting a punch assembly including a plunger having a cutting edge on an impact end thereof, said plunger being slidably affixed to said framework and movable between retracted and extended positions;
- and
- wherein said anvil includes an aperture for receiving the cutting edge of said plunger when in the extended position.
A method for cutting a hole through one or more sheets, the method comprising the steps of:
- positioning a hole punch's detached base adjacent a first side of one or more sheets, the base supporting an anvil;
- positioning a punch assembly adjacent an opposite side of the one or more sheets to magnetically couple the detached base to the punch assembly whereby the anvil is aligned with cutting means of the punch assembly;
- and
- punching a hole through said one or more sheets by forcibly moving an extendable plunger of said punch assembly through said one or more sheets against the base.
