Abstract
A pair of rigid hollow tubular members are telescoped together with one of the members having a series of spaced-apart grooves running parallel to the axis and the other having a series of spaced-apart ribs running parallel to its axis with the ribs slidably engaged in the grooves and means for releasably applying radial force between the two tubular members to force the ribs and the grooves into tight engagement to frictionally lock the tubular members together in a very stable fashion so they support a load without wobbling yet can be released when necessary.
Claims10
A support assembly, comprising:
- a first rigid tubular member having a plurality of elongated spaced-apart grooves parallel to its axis:
- a second rigid tubular member having a plurality of elongated spaced-apart ribs parallel to its axis:
- said first and second tubular members telescoped together with said ribs slidably engaged in said grooves;
- and
- means for releasably applying a radial force to one of said tubular members to bring said ribs into tight frictional contact within associated grooves to frictionally lock said tubular members together.

A support assembly, comprising:
- a) a base, said base comprising a rigid plate member for resting on a support surface and a rigid hollow tubular member extending axially of said plate member, said base tubular member having a plurality of elongated spaced-apart ribs parallel to its axis;
- b) a second rigid hollow tubular member, said second rigid tubular member having a plurality of elongated spaced-apart grooves parallel to its axis;
- c) means for attaching said second tubular member to a carrying device;
- d) said second tubular member telescoped with said base tubular member with said ribs slidably engaged in said grooves;
- and
- e) means for releasably applying a radial force to said base tubular member and said second tubular member for placing said fibs in fight frictional contact with associated grooves to frictionally lock together said base tubular member and said second tubular member.
