Claims9
A toggle clamp formed in one piece from plastic material suitable for use in forming a live hinge, said clamp comprising:
- a pair of elongated jaws having one pair of ends lying in a bisector plane longitudinally of said clamp and interconnected by a single live hinge for pivotal movement of said jaws toward and away from one another;
- and
- a pair of toggle members having a first pair of adjacent ends interconnected by a common live hinge and their remote ends connected to opposed ends of a respective one of said jaws by separate live hinges, said jaws being movable between a freely pivotable open position and immovable closed position as said toggle members are pivoted to shift said common live hinge from an open position remote from said single live hinge to a closed jaw-locking position between said single live hinge and a straight line through said hinges connecting said toggle members to said jaws.
