Pipe coupling having compression band
First Claim
1. A pipe coupling positionable straddling facing end portions of a pair of pipe elements for securing said pipe elements together in end to end relationship, said pipe coupling comprising:
- a deformable sealing member having an inner diameter sized to receive said pipe elements and an outer surface;
a plurality of segments supported on said outer surface of said sealing member, said segments being positioned circumferentially around said sealing member in predetermined spaced apart relation to one another, each said segment having a pair of arcuate surfaces positioned on opposite sides of said sealing member, said arcuate surfaces being engageable with said pipe elements to retain them in said end to end relationship;
a compression band extending around an outer perimeter of said segments, said compression band having opposite ends in facing relation, said segments being captured between said compression band and said sealing member; and
a tensioning member mounted on said compression band between said opposite ends, said tensioning member being adjustably tightenable for applying tension to said compression band and forcing said segments substantially radially inwardly against said sealing member, tightening of said tensioning member moving said arcuate surfaces into engagement with said pipe elements.

Abstract
A coupling for joining pipe elements in end to end relationship is disclosed. The coupling includes a sealing member having an inner diameter and an outer surface. A plurality of segments are supported on the sealing member'"'"'s outer surface. Each segment has a pair of arcuate surfaces positioned in space relation on either side of the sealing member. A compression band surrounds the outer perimeter of the segments, the segments being captured between the band and the sealing member. The pipe elements are inserted into the inner diameter between the segments. A tensioning member is mounted on the band. Tightening of the tensioning member causes the compression band to force the segments radially inwardly into engagement with outer surfaces of the pipe elements.

21. A pipe coupling positionable straddling facing end portions of a pair of pipe elements for securing said pipe elements together in end to end relationship, said pipe coupling comprising:
-
a deformable sealing member having an inner diameter sized to receive said pipe elements and an outer surface;
a plurality of segments supported on said outer surface of said sealing member, said segments being positioned circumferentially around said sealing member in predetermined spaced apart relation to one another, each said segment having a pair of arcuate surfaces positioned on opposite sides of said sealing member, said arcuate surfaces being engageable with said pipe elements to retain them in said end to end relationship;
a compression band extending around an outer perimeter of said segments, said segments being captured between said compression band and said sealing member;
a projection mounted on each of said segments and extending outwardly therefrom, said compression band having a plurality of apertures therein for receiving said projections, engagement of said projections with said apertures limiting relative motion between said segments and said compression band and maintaining said segments substantially in said predetermined spaced apart relationship; and
a tensioning member mounted on said compression band, said tensioning member being adjustably tightenable for forcing said segments substantially radially inwardly against said sealing member, tightening of said tensioning member moving said arcuate surfaces into engagement with said pipe elements. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
