Abstract: A failsafe stable cleat with automatic in-line line-locking includes a frame having proximate and a remote sides on substantially opposite sides of the frame and formed with a passageway, extending between the proximate and remote sides, for receiving a line and generally defining a cleat center line along which a line can move along a first line releasing direction from the proximate to the remote sides and a line pulling direction from the remote to the proximate sides; attaching members for attaching the frame to a support surface. A cam on the frame on one side of the passageway has a line engaging portion spaced a predetermined distance from the support surface, the cam being movable between a line releasing position and a line locking position.

Abstract: A failsafe device for raising/lowering articles includes a frame and a fastener for attaching the frame to a ceiling or wall to elevated an article above the floor. A pulley or sheave is mounted on the frame about a substantially horizontal axis when the frame is mounted on the ceiling or wall. A line is entrained over the pulley and has a substantially vertical lifting line portion attachable to the article to the lifted and a substantially vertical pulling line portion arranged to be pulled downwardly by a user to elevate the article and raised upwardly to lower the article. A cam is mounted on the frame on one side of the pulling line portion and has a line engaging surface.
