Patent ID: 8052761

Claim:
A voluntary opening terminal device, comprising: a base; an elongate movable digit pivotally attached to the base at a proximal end and having a distal end, the movable digit movable between a closed position and an open position; an elongate fixed digit attached to the base at a proximal end and having a distal end, the distal end of the fixed digit abutting the distal end of the movable digit when the device is in a closed position; at least one spring member interconnecting the two digits, the spring member having a first end and a second end; a mechanism associated with one of the two digits and slidable between a plurality of positions spaced along the one digit, and one end of the spring member interconnected to the mechanism such that movement of the mechanism between the plurality of positions changes the force at which the moveable digit closes against the fixed digit, wherein the mechanism automatically locks in a position regardless of where it is positioned, wherein both ends of the spring member are interconnected to the mechanism; and, wherein the mechanism comprises a crossbar that extends through the one digit, the crossbar has a first end and a second end, the first end is interconnected to the first end of the spring member, and the second end is interconnected to the second end of the spring member.
