ABSTRACT:
A movement blocking apparatus having an inner locking ring rotatably mounted within a housing is disclosed. The housing contains slits which, in a locked position, align with inclined plane portions of the locking ring. Notches reside axially adjacent to the inclined plane portions of the locking ring. A blocking pin, which blocks movement of a shaft, is inserted in the housing slits, causing the locking ring to rotate away from the locked position due to operation of the blocking pin against the inclined planes. When the blocking pin has been inserted into the slits far enough to engage the locking ring notches, a spring causes the locking ring to return to the locked position and entrap the blocking pin.
