ABSTRACT:
A stud for interengagement with a rigid receptacle to form a fastener assembly. The stud includes an elongated body member with an enlarged head on one end. A gripping surface is on the head to facilitate gripping and rotation of the stud. A spring is also on the head to facilitate axial movement of the stud with respect to the rigid receptacle. One end of the stud has a spiral cam slot terminating in a locking detent thereon. Therefore, when the stud and receptacle are positioned on one of two members respectively and brought into interengagement, the cam slot will be aligned with each cam follower. Thereafter relative rotation between the stud and receptacle will cause the cam follower to enter the cam slot until seated in the locking detent with the assistance of the spring permitting axial movement of the stud with respect to the rigid receptacle thereby locking the two members together. Relative rotation between the stud and receptacle in the opposite direction will move each cam follower from the locking detent and along the cam slot until disengagement occurs whereupon the stud and receptacle can be separated and the two members released with the assistance of the spring permitting axial movement of the stud with respect to the rigid receptacle.
