<p>A coupling for joining pipe elements in end to end relation is disclosed. Interconnectable pipe coupling segments (52), each positionable straddling a sealing member and end portions of a pair of pipe elements engaged with said sealing member for securing said pipe elements together in end-to-end relationship, wherein each said segment comprises:
a pair of arcuate surfaces (54, 56) adapted to interface with the outer surfaces of said pipe elements;
first and second connection members (72, 74) positioned at opposite ends of said arcuate surfaces for adjustably connecting one coupling segment to another, said connection members being adjustably tightenable for drawing said segments together;
first and second angularly oriented surfaces (66, 68) positioned adjacent to said first and second connection members (72, 74) respectively, said angularly oriented surfaces (66, 68) having opposite slopes, said angularly oriented surfaces (66, 68) on one said segment being positionable in facing relation with angularly oriented surfaces (66, 68) on another said segment and engaging one another when said segments are drawn together and causing said segments to rotate relatively to one another about an axis oriented substantially perpendicular to said pipe elements; and
a concavity (86) positioned between said arcuate surfaces and extending circumferentially around said segment, said concavity (86) being divided into a plurality of sectors (88, 90, 92), at least one of said sectors being oriented angularly with respect to said axis substantially perpendicular to the longitudinal axis of said pipe elements to receive said sealing member.</p> |
