Abstract
A high capacity paper clip which is able to accommodate thin or thick insertions of paper. The paper clip is formed by bending a continuous elongated oval loop of wire over onto itself with a first bent portion of the loop longer than a second bent portion, leaving a tensioning expansion loop at the bend in each arm of the shorter bent portion to allow the paper clip to expand wide for the insertion of bulky stacks of paper.
Claims1
A high capacity paper clip device made from a single closed loop of wire bent into a shape allowing the retention of a wide range of thicknesses of stacks of paper retained therebetween, the device comprising:
- a high capacity paper clip comprising a single oval loop of continuous wire with no single wire ends, the single oval loop of continuous wire having an off-center bend forming two overlapping parallel U-shaped jaws each comprising two parallel wire arms and an interconnecting curved outer end between the two wire arms, one of the U-shaped jaws being longer than the other, the two overlapping U-shaped jaws contacting each other along most of the length of each of the arms with an outer end of one of the U-shaped jaws extending beyond the outer end of the other of the U-shaped jaws, and a portion of one of the U-shaped jaws further comprising a loop in each of the wire arms curved outwardly away from the other of the U-shaped jaws adjacent to the off-center bend to form an expansion portion enabling the two U-shaped jaws to expand over a wide range of separation of the two U-shaped jaws to maintain a wide range of thicknesses of stacks of paper between the two U-shaped jaws while maintaining a substantially parallel relationship between the outer ends of the two U-shaped jaws.
