DEFINITION

Classification: 24/581

Formations positioned along wall forming mating-member-guiding cavity:

(under subclass 580) Plural formations member having its spaced, distinct structural formations located on a surface which at least partially defines one wall of a cavity utilized by this member to guide an inserted portion of the mating member towards its final interlock position with the formations.

(1) Note. A cavity which is proper for this and the indented subclass may or may not fully encircle the segment of the pathway along which the selectively interlocking member travels during its initial insertion. However, if it only partially encircles this location, then it must clearly limit the movement of the inserted member in at least two directions which are perpendicular to the direction of its travel and in opposite directions to one another at this location.
