INCREASED AND VARIABLE FORCE AND MULTI-SPEED CLAMPS

摘要

A method of operating a clamp (100) that includes a first clamping jaw (102), a support element (104) to which the first clamping jaw is attached and a trigger handle (118) pivotably mounted to a clamp body (112). The method includes actuating the trigger handle causing the first clamping jaw to experience incremental motion and varying the incremental motion as a function of a load encountered by the support element by varying an effective lever arm of the trigger handle by moving a fulcrum point into contact or out of contact with the trigger handle based on the load.

1. A clamp comprising:
a first clamping jaw; a support element to which said first clamping jaw is attached; a clamp body having a slot through which said support element passes; a handle grip attached to said clamp body; a trigger handle pivotably mounted to the clamp body; a trigger handle reinforcement attached to said trigger handle; a driving lever that is movable to a first position where said driving lever engages said support element and causes said support element to move relative to said clamp body; and wherein pivoting of said trigger handle causes said trigger handle reinforcement to pivot and engage said driving lever.
