DEFINITION

Classification: 24/643

Having pivotally connected interlocking component:

(under subclass 629) Receiving member having its relatively movable projection engaging or guiding component connected to its other projection engaging or guiding component in a

manner allowing it to both (a) swing in an arcuate path about a constantly contacted connection point or region located on either the other component or an intermediate linking portion of the member, and (b) maintain the required relative movement between the surfaces of the components or the component and linking portion at the contact point or region.

SEE OR SEARCH THIS CLASS, SUBCLASS:

609+, for a receiving member having a pivotal connection between two components which allows relative movement between two, distinct, inserted components of its projection.

684, for a pivotal, mounting connection allowing bodily movement of the projection or cavity towards its interlocking connection.
