DEFINITION

Classification: 187/371

Slideably mounted contact component:

(under subclass 361) Retaining, halting, or retarding means having its relatively moving engaging part connected to another part of the means, or to the structure attaching it to the load-underlying support surface, by two distinct, rigid or semirigid formations which (1) are each integral with or attached to a different one of the parts or part and attaching structure and (2) have mutually cooperating surfaces both (a) in gliding contact with each other and (b) restricting the relative movement of the engaging part to substantially a single primary direction.
