Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
134 words
A forcep construction for grasping and holding under virtually uniform pressure articles of different shape and construction, comprising in combination: a one piece forcep member of resilient flat stock material; said member including a pair of arms normally in spaced relation, a hinge portion integrally interconnecting said arms, said hinge portion being of selected radius; each of said arms including an angle cross section progressively changing from slightly less than 180* adjacent said hinge portion to about 90* at the end portion of each arm; said angle cross section arms facing in the same direction for nesting one arm within the other arm whereby the exterior surface of one angle section is pressable into close proximity and engagement with the interior surface of the other arm for firmly holding an article between said surfaces.
