DEFINITION

Classification: 24/666

And closed elongated access opening for guiding transverse projection travel after insertion:

(under subclass 662) Receiving member having a component or segment with connected walls which (a) fully encircle the access path of the projection into the cavity, and (b) have a configuration with one dimension of greater length than the corresponding dimension of the projection in its insertion attitude to allow the projection after insertion therethrough to abruptly change its direction of movement and bodily travel a significant distance along the encircling walls in a path which is transverse to the access path.

(1) Note. The distance traveled by the projection during its transverse movement should be at least half of the projection's length in its corresponding dimension to be considered significant.

(2) Note. A section of the fully encircling walls may be formed by a portion of the structure-to-be-secured* connected to two other wall sections of the component or segment.

(3) Note. If no abrupt change in travel direction is necessary by the projection after its insertion through the access opening, then it is not proper for this and the indented subclasses.

(4) Note. A minor expansion gap in the access opening encircling wall which does not allow any of the projection member's structure to pass therethrough is still considered to be "fully encircling" and proper for this and the indented subclasses.
