Abstract
An adjustable rope lock including a body of material having converging passageways extending therethrough with the passageways terminating at one edge of the body in a joined, merged passageway and terminating at an opposite edge of the body in spaced relation with the rope being threaded through the passageways with the two ends of the rope extending outwardly from the merged passageway at one edge of the body. The merged passageway from which the free ends of the rope extend is generally elliptical in shape although the specific configuration can vary with the ropes being positioned one above the other with one rope supporting a load and forming a taut rope segment. The other rope is the adjustable rope and forms a pull rope segment which may be pulled freely to take up slack, maintain or increase tension.
Claims14
An adjustable rope lock comprising a body having opposed surfaces, means supporting said body from a supporting structure, said body including a pair of passageways extending between and communicating with- the opposite surfaces, said passageways having one of their ends in spaced relation in one of said opposed surfaces, the other ends of said passageways merging and joining into a single, generally elliptically shaped opening in the other of said surfaces, a flexible rope extending through said passageways with the free ends of the rope exiting from the generally elliptical opening with one of the rope segments being above the other as they exit from the generally elliptical opening with the upper rope segment being taut and the lower rope segment being loose to form a pull rope segment whereby the taut rope segment will bear against and frictionally lock the pull rope segment against linear movement into the generally elliptical opening when the taut rope segment is oriented in an angular position extending outwardly and downwardly from the body with the pull rope segment being movable outwardly in a linear direction when the pull rope segment is located below the taut rope segment.
An adjustable rope lock comprising a body having a pair of angularly disposed passageways therethrough, a rope extending through the passageways, one end of the passageways merging into a single elongate opening at one surface of the body and including spaced ends at another surface of the body and means supporting said body whereby the angle of a taut rope segment of the rope approaches the line of resistance provided by the body to the force exerted on the taut rope segment, to frictionally lock the rope segments when the taut rope segment approaches said line of resistance.
An adjustable rope lock comprising a body having opposed surfaces, means supporting said body from a supporting structure, said body including a pair of passageway extending between and communicating with the opposite surfaces, said passageways having one of their ends in spaced relation in one of said opposed surfaces, the other ends of said passageways merging and joining into a single oval shaped opening in the other of said surfaces, a flexible rope extending through said passageways with the free ends of the rope exiting from the elongate opening as rope segments, one of said rope segments being above the other as they exit from the elongate opening with an upper rope segment being taut and a lower rope segment being loose to form a pull rope segment whereby the taut rope segment will bear against and frictionally lock the pull rope segment against linear movement into the elongate opening when the taut rope segment is oriented in an angular position extending outwardly and downwardly from the body with the pull rope segment being movable outwardly in a linear direction when the pull rope segment is located below the taut rope segment, said passageways converging toward said elongate opening with at least a portion of the passageways being spaced apart by a wedge-shaped component of said body.
