DEFINITION

Classification: 446/124

Interfitting elements:

(under subclass 85) Device wherein a detached part has a distinctly shaped portion for cooperative engagement with another part or with a connector for plural parts.

(1) Note. This definition attempts to avert the determination of whether a particular item is an element or a connector. Area of an engagement or joint in this or its indented subclasses refers either to a connection between major construction elements or to a connection between major element and an intermediate fastener.
