A fluid swivel joint coupling has a body member, a first connecting member and a second connecting member. The body member includes an inlet portal, and outlet portal and a diverted fluid passageway connecting them. The first connecting member is pivotably mounted in flow communication with one of the portals for rotation about a first swivel axis, and the second connecting member is pivotably connected in flow communication with the other portal for rotation about a second swivel axis. The second connecting member has a diverted fluid passageway opening onto a third portal, a longitudinal axis extending through the third portal and a portion of the passageway. The first connecting member is operatively connected to a rigid conduit while the second connecting member is operatively connected at the third portal to a flexible conduit. The axes are disposed such that the longitudinal axis is never in the plane which passes through the first swivel axis parallel to the second swivel axis, so that the longitudinal axis may align itself with the direction of any flexible force applied through the flexible conduit. The body member and the second connecting member may have interlocking elements which cooperatively couple, and which uncouple when a tensile force above a predetermined limit is interposed between the flexible conduit and the rigid conduit.
A fluid swivel joint coupling having a body member including an inlet portal, an outlet portal and a diverted fluid passageway therebetween, a first connecting member pivotably connected to and in flow communication with a first of the portals for rotation about a first swivel axis passing through the first portal and the body member, a second connecting member pivotably connected to and in flow communication with the second of the portals for rotation about a second swivel axis passing through the second portal and the body member, means for connecting said first connecting member to a rigid conduit, said second connecting member having a diverted fluid passageway including a longitudinal axis extending through a third portal, means for connecting said second connecting member to a flexible conduit with the third portal in flow communication therewith so that fluid may flow through the swivel joint between the rigid conduit and the flexible conduit, the longitudinal axis of the second connecting member being disposed relative to the first and second swivel axes such that said longitudinal axis is never in that plane which passes through the first swivel axis and is parallel to the second swivel axis.
