ABSTRACT:
An adjustable clamping assembly is disclosed that includes first and second blocks each having a passageway through which support rods are inserted. The blocks may be rotated relative to each other. In one embodiment, each block has a slot extending from one face of each block to the passageway housing the support rod. The second block includes a frusto-conical seat for receiving a frusto-conical bearing member of the first block. A partially threaded stem extends from the first block coaxial with the bearing member and is inserted through an aperture in the second block. The stem is inserted within the tapped portion of a handle for adjusting the tightness of the assembly. As the handle is tightened the slots compress thereby securing the support rods in a fixed position within the passageways. In another embodiment, the first block includes a set screw instead of the slot for securing the support rod in a fixed position. The support rod has a flat portion so that when the set screw is adjusted away from the rod it may rotate about its longitudinal axis. A bushing may be provided in the passageway of the first block to facilitate rotation of the rod. In yet another embodiment, the first block includes a recess for receiving one end of the support rod so the rod is substantially parallel with the stem of the first block. A set screw is provided to secure the rod within the recess.
