ABSTRACT:
An automatic locking device (402) is disclosed that can be utilized to secure a first member (40) to a second member (10). The device includes a latching member (12) with an integral spring member (18), the latching member being attached to a bolt member (11). The bolt member (11) is inserted into the first member (40) and then is inserted in an opening (15) in the latching member (12). Thereafter, an E-shaped retaining ring (13) is attached to a shank end of the bolt member (11) to secure the bolt member (11) to the latching member (12). The spring member (18) is continuously biased via a projecting portion (410) in the first member (40). When the first and second members are properly engaged with one another, the latch member (12) enters a detent (116) in the second member (10) and retains the first member (40) securely in place. Thereafter, the bolt member (11) can be rotated to release the latching member (12) from the detent (116) facilitating detachment of the first member (40) from the second (10).
