DEFINITION

Classification: 187/332

Collapsible or rollable type:

(under subclass 325) Subject matter wherein the stationary path blocking means has two distinct edges which are connected to each other by load blocking structure which permits the edges to move either closer together by reducing one of its dimensions (e.g., folds compact, winds around one of the edges) when the path of the load is cleared or spread apart by expanding one of its dimensions when the path of the load is blocked thereby.
