Abstract
A releasable lock mechanism is provided in combination with a stationary first member and a second member, the latter being adapted to assume various selected positions of rotary adjustment with respect to the first member. The lock mechanism includes a first lock component carried by one of the members and a complemental pivotally adjustable second lock component carried by the other member. The first lock component has a rounded periphery which is provided with a plurality of annularly spaced pockets; each pocket corresponding to a selected position of rotary adjustment of the second member with respect to the first member. The second lock component assumes an interlocking engagement with a peripheral pocket, when the second member is disposed at a selected position of rotary adjustment with respect to the first member, and retains the second member in the selected position. The second lock component is adapted to be manually shiftable relative to its pivotal axis and away from the peripheral pocket of the first lock component to effect unlocking of the lock components.
