1. A coupling segment for a hingeable segmented pipe coupling, including;
- an arcuate member having an internal recess for the reception of a sealing gasket; and
,bolting pads at the respective ends of said arcuate member for the reception of securing members, whereby a plurality of said coupling segments can be assembled into a segmented pipe coupling;
further includingat least one said bolting pad including a planar bolting face portion and an opposite face portion extending radially of the longitudinal axis of said coupling segment, and, an arcuate bolting face portion providing an outward continuation of said planar bolting face portion;
said arcuate bolting face portion comprising a curved surface having its longitudinal axis of generation extending parallel to said opposite face of said bolting pad and extending parallel to the longitudinal axis of said coupling segment;
said opposite face of said bolting pad terminating adjacent said arcuate member in a recessed portion extending inwardly at an angle relative to said planar bolting face portion and towards the longitudinal axis of said coupling segment.

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.

32. A hinged segmented pipe coupling provided by:
-
at least two arcuate members each having an internal recess for the reception of a sealing gasket; bolting pads at the respective ends of each said arcuate member; and securing members respectively securing one bolting pad of each said arcuate member to an adjacent bolting pad of an adjacent arcuate member; at least one pair of said bolting pads each including a planar bolting face portion and an opposite face portion extending parallel to the longitudinal axis of said arcuate members, and, an arcuate bolting face portion providing an outward continuation of said planar bolting face portion; the respective said arcuate bolting face portions each comprising a curved surface having its longitudinal axis of generation extending parallel to said opposite face of the associated bolting pad, and extending parallel to the central longitudinal axis of said coupling; each said opposite face of each said bolting pad terminating adjacent said arcuate member in a recessed portion extending inwardly at an angle relative to said planar bolting face portion and towards the longitudinal axis of said coupling.
