DEFINITION

Classification: 24/590

Projection or cavity rotates about axis of cavity access opening to interlock:

(under subclass 588) Dissociable mating members, wherein either the projection or an opposed member engaging or guiding portion of the projection or the receiving member is rotated about the central axis of the cavity's access opening (i.e., the portion of the cavity defining the opening through which the projection initially enters) after or during the insertion of the projection into the cavity to complete the interlock between the members.
