Abstract
A clamp device for clamping first and second telescopically mounted tubes comprising a preformed bolt clamp and a saddle element. The preformed bolt clamp is of unitary and substantially rigid material and has a center portion and opposite end portions. The center portion extends completely around the outer surface of the outer tube with the end portions thereof extending outwardly from the outer tube in substantially the same direction. The saddle element generally comprises a center portion positioned between end portions which have openings formed therein to receive the end portions of the bolt clamp. The center portion of the saddle element is provided with an upwardly extending rib which not only strengthens the saddle element but also provides a contact point between the saddle and the helical bolt clamp. Fastening and tightening means comprising nuts are mounted on the end portions of the bolt clamp and are tightened to draw the saddle element into tight, intimate and continuous engagement with the adjacent part of the center portion of the bolt clamp, and to draw the center portion of the bolt clamp into tight, intimate and continuous engagement with the outer surface of the outer tube element. The saddle element has a configuration such that it is spaced from the outer surface of the portion of the outer tube element adjacent the center portion of the bolt clamp so that the saddle element bears against the adjacent part of the center portion of the bolt clamp. When the nuts are completely tightened, the end portions of the saddle element bear against the outer tube at approximately three o'clock and nine o'clock.
