ABSTRACT:
A locking mechanism for locking a first member in any one of an infinite number of positions relative to a second member includes a resilient members for urging the first and second members toward each other to apply a friction force between the first and second members to prevent relative movement between the first and second members. An actuator member for releasing the friction force between the first and second members has a first position in which the first and second members are prevented from moving relative to each other. The actuator member has a second position in which the first and second members are positionable relative to each other. The locking mechanism includes a handle for moving the actuator member from its first position to its second position to release the friction force between the first and second members. The resilient members is operable to move the actuator member from its second position to its first position.
