DEFINITION

Classification: 187/379

Pivotally attached contact component:

(under subclass 377) Retaining, halting, or retarding means in which the relatively movable engaging part is connected to the load-underlying support surface in a manner allowing it to both (a) swing in an arcuate path partially about a constantly contacted connection point or region which travels with the support surface and (b) maintain movement between the part and connection at their contact point or region.

(1) Note. Patents with an engaging part which revolves completely around the contacted point or region (e.g., a rotating guide wheel with a brake) are not proper for this and the indented subclasses and are found in subclass 377.
