Abstract
In general, the invention consists of a staff holder that includes a supporting base, a vertical post attached to the supporting base and a hand actuated chuck at the top of the post. The chuck includes an inner ring fixed to the post, a plurality of gripping jaws supported in the ring for transverse movement relative to the central vertical axis of the post, an outer ring mounted on the inner ring for rotation about the vertical axis of the post and a camming mechanism for causing the gripping jaws to move transversely relative to the inner ring upon manual rotation of the outer ring. More specifically, the post of the holder is removably connected to the base.

- (1) an inner ring fixed to the upper end of said post, said inner ring having a cylindrical chamber, a top opening to said chamber for enabling said staff to be inserted into said chamber and a plurality of horizontal slots to said chamber at different angular positions about said axis, said chamber having a vertical central longitudinal axis;
- (2) a gripping jaw in each of said horizontal slots, each of said gripping jaws being supported on said inner ring for horizontal movement relative to said inner ring toward and away from said central longitudinal axis;
- (3) an outer ring mounted on said inner ring for rotation about said central longitudinal axis;
