Abstract
An articulable joint with two opposing disk-like joint portions or plates which are joined by and pivot about a central locking bolt. The joint portions also engage each other via ball and ball seat contact points. Spring pressed balls on one joint portion are biased into ball seats formed in the other joint portion such that the joint may be pivoted incrementally to a number of positions. The spring pressed balls are separately housed in individual ball plungers which in turn are threaded into its respective joint portion such that the ball plungers are selectively adjustable to vary the amount of turning or pivoting force that is required to unseat the balls from their respective seats and move them to respective adjacent seats.
