| Abstract: |
Two arms are pivotally connected at their upper ends. Each arm has at its lower end a rounded gripping surface comprising a tip made of a high-friction material. At the pivot, there is a spring urging the arms apart. When in use, the tool is held so that the tips of the arms touch the paper to be lifted, the arms are pressed together until they are side by side, a portion of the paper is caught and pinched between the arms, and the paper is lifted and separated from the stack.

First Claim:
Show all 4 claims |
What is claimed is:
1. A hand-sized pick-up device providing means for finger and thumb controlled manipulation of a plurality of sheets comprising:
- (a) a first arm having a free end and a fixed end,
- (b) a second arm having a free end and a fixed end,
- (c) hinge means integrally joining together each of said fixed ends at a point defining an apex,
- (d) a high-friction tip of a rubber-like material having a high tack attached to the free end of each arm, each tip having the form of a cap having an outwardly facing semi-spherical face portion whereby when the tips are placed against a stack of flexible paper sheets and the arms are squeezed together, a single sheet of paper is secured between the tips for lifting from the stack, and
- e) a structural cross-member integrally formed with each arm near the apex defining an aperture between the cross-member and the apex and providing structural integrity and a pivoting fulcrum for each arm of the pick-up device adjacent the apex, each arm further including
- a post portion integrally formed with the free end of the arm,
- mounting means on the post portion for engaging the tip,
- a flange extending longitudinally of each arm for providing structural reinforcement of the arm, and
- a gusset integrally formed with the flange and post portion for providing structural reinforcement of the joint between each arm and the post portion.
