Abstract
This invention relates generally to a manual toggle clamp for use in fixturing. The clamp includes an operating arm that is pivotally supported on a support block and a pair of outboard clamping links which share a common pivot axis and are supported on the support block. A pair of intermediate links interconnect the operating arm and the clamping links such that movement of the operating arm causes the clamping links to rotate. The elements of the clamp are configured such that they form an over-center linkage which prevents the clamping links from being moved out of a clamping position except by movement of the operating arm. The outboard clamping links provide a mounting surface for one or more clamping arms of the type typically used with power clamps.
