DEFINITION

Classification: 24/598.1

Projection passes through cavity then moves toward noninserted portion of its member to complete interlock (e.g., snap hook):

(under subclass 588) Projection member in which the projection first passes completely through the cavity of the mating member and then relatively moves toward a directly cooperating noninserted portion (i.e., a portion which is not inserted into the cavity of the opposed member) of its member which is connected or linked to the projection in a manner allowing the movement therebetween needed to complete the interlocking of the projection and receiving members.

(1) Note. To be proper for this and the indented subclasses the cooperating passed-through and noninserted portions of the projection member must not have any section of the structure-to-be-secured*, a support therefor, or the cavity member located between the nearest segments of their relatively movable cooperating surfaces. Projections of this type are found in subclasses 604+ below.
