Abstract
A failsafe cleat with automatic in-line locking cam includes a frame having proximate and a remote sides on substantially opposite sides of the frame and formed with a passageway, extending between said proximate and remote sides, for receiving a line that can move along a first line releasing direction from said proximate to said remote sides and a line pulling direction from said remote to said proximate sides. A locking cam on the frame on one side of said passageway has a line engaging portion, the cam being movable between a line releasing position and a line locking position. The line engaging portion includes a first engaging portion normally spaced a distance Δ from the line to form a clearance gap in the line releasing position and a second engaging portion bridging the gap a distance equal to at least Δ for arresting the line and preventing movement of the line in the line releasing direction. A pusher on the frame on an opposite side of said passageway in relation to said cam means selectively applies a force on the line in the direction of said cam for urging the line across the clearance gap the distance Δ into contact with the first engaging portion only when tension …
