초록

A ratchet-type tensioning mechanism for a rope or cord has a rotatable sheave with faces having radially extending serrations. A releasable ratchet mechanism permits rotation of the sheave in one direction but not the other. A plurality of serrations circumscribes the sheave, which is closely fitted within a curved surface within a housing within which the sheave is rotatably mounted. The curved surface forces the rope into the sheave and maintains it in non-slippiong contact therewith. An opening in the side of the housing can be provided to permit hand...
