ABSTRACT:
A self-locking device for locking a movable member to a stationary member including a rotatable latch member mounted on the stationary member and having a pair of ears located on opposite sides of its axis of rotation, the movable member having a pair of heels cooperations with the ears of the latch member in such a way that longitudinal movement of the movable member relative to the stationary member and toward the closed position causes one of the heels to engage one of the ears on the latch member thereby rotating the latch member until the other ear engages the other heel to latch the movable member in the closed position, the face on the other ear and the face on the other heel being angularly positioned with respect to the axis of rotation of the latch member such that movement of the other heel toward the open position will not impart any substantial rotary movement to the latch member to cause it to rotate to an unlatched position, thereby preventing movement of the movable member in the opening direction.
