ABSTRACT:
A joint mechanism comprised of two pivotally connected joint members rotatable about a common axis is lockable in one of a series of predetermined positions by engagement of a spring-biased pawl provided within one joint member within notches distributed about the peripheral edge of the other joint member. An operating lever comprised of a forked release element and a handle pivotally connected together cooperates with a control means to control locking and unlocking of the joint mechanism. The control means has radially extending resilient arms formed at the free end with upturned claws which, when projecting through slits formed in one side of the other joint member, prevents engagement of the pawl within said notches, and which, when being depressed into said slits by the release element of the operating lever, permits engagement of the pawl within the notches.
