A releasable lock mechanism.

摘要

O A releasable lock mechanism is provided in combination with a stationary first member (11)and a second member (14), the latter being adapted to assume various selected positions of rotary adjustment with respectto the first member (11). The lock mechanism includes a first lock component (15) carried by one of the members and a complemental pivotally adjustable second lock component (17) carried by the other member. The second member (14) is disposed at a selected position of rotary adjustment with respect to the first member (11), and retains the second member (14) in the selected position. The second lock component (17) is adapted to be manually shiftable relative to its pivotal axis and away from the peripheral pocket of the first lock component (15) to effect unlocking of the lock components (15,17). The locking mechanism is particularly suitable for locking the rear end of a truck or similar vehicle to a loading dock during loading and unloading.
