Abstract
A hingeable segmented pipe coupling includes dual or plural coupling segments which are hingeable relative to each other in the absence of transverse hinge pins, at least one pair of bolting pads including arcuate surfaces which roll with respect to each other, and each of which includes a fulcrum for engagement with a headed securing member associated with those bolting pads. In preferred embodiments, the bolting faces of the bolting pads are contoured to prevent rotational movement of the coupling segments about the axis of the securing member.
