DEFINITION

Classification: 242/608.2

Mechanical joint or fastener:

(under subclass 608) Subject matter wherein the joining means connecting the rim to winding drum (hub) or other rim includes compound interlocking surfaces formed on at least one of the components.

(1) Note. For placement in this and the indented subclasses, the joint should include a retaining surface transverse or oblique to the direction in which the components are introduced for assembly. Thus, a simple tapered or resilient joint relying solely on friction or compression would be classified above.
