Abstract
The present invention relates to a work holding and clamping device, which increases the usable span to almost twice its stored length. This clamping device has an inner and outer assembly which are nested, and each assembly is made of a rectangular tube with a jaw affixed to one end. The inner assembly contains a locking mechanism to allow for length adjustment. When arranged so that the jaws are on the same side of the respective assemblies, the clamp is capable of a span that is almost equal to the length of the inner assembly. When arranged so that the jaws are on opposite sides of the respective assemblies, the clamp is capable of a span that is almost equal to the sum of the length of the inner assembly and outer assembly.
Claims7
A clamping device for restraining a workpiece comprising:
- an inner tube and outer tube having telescopic characteristics, a shared medial axis, and each having a generally square cross section enabling the inner tube to be received by the outer tube at discrete rotations of 0, 90, 180, and 270 degrees relative to the medial axis, and ends of the outer tube being configured to receive distal end of the inner tube;
- a pair of opposing jaws perpendicular to the medial axis including a first jaw secured at proximal end of the inner tube and a second jaw secured at distal end of the outer tube;
- and
- a locking device located at the distal end of the inner tube which includes a locking plate having a leading edge which extends-from and retracts-into an interior of the inner tube through an aperture under the influence of a locking control system.
