ABSTRACT:
A jamming cleat has a groove to receive and grip a rope. At least a part of the depth of the groove has facing side walls each of which is formed with a plurality of ridges. The edges are inclined upwardly from the base of the groove towards one end of the groove, and the crests of the ridges on each side of the groove lie generally in one common ridge crest plane. The ridge crest planes converge downwardly towards the bottom of the groove and diverge lengthwise of the groove away from the said one end of the groove. In use a rope or cord is laid in the groove and pulled through the groove in a direction away from the said one end of the groove. The ridges draw the rope down towards the bottom of the groove so as to jam the rope in the groove. The extent to which the rope is drawn down into the groove increases progressively away from the said one end but the rope is gripped generally uniformly along the length of the groove because of the divergence of the ridge crest planes.
