Abstract
A support which includes two or more pole sections hingedly interconnected by a hinge permitting the support to be folded for storage purposes. At least one of the pole sections has a pair of portions disposed in telescopic relation for sliding movement providing a fast coarse adjustment to the length of the support. The sliding movement is lockable at various relative positions by a quick release coupling which, upon locking the sliding telescopic movement, converts to a screw thread fine adjustment for changing the length of the support. A releasable lock mechanism is also provided for locking the pole sections when they are in line in an end-to-end position.
