Coupling with tongue and groove
First Claim
1. A pipe joint assembly comprising:
- a first pipe element, the first pipe element defining an end and an outer surface;
a second pipe element, the second pipe element defining an end and an outer surface, the end of the first pipe element positioned in an end-facing relationship with the end of the second pipe element;
an annular gasket, the annular gasket defining a coupling void, the end of the first pipe element and the end of the second pipe element disposed within the coupling void, the annular gasket forming a seal with the outer surface of the first pipe element and the outer surface of the second pipe element;
a pair of segments, each segment being approximately semi-circular and defining a first end and a second end, each segment comprising a fastener pad protruding proximate to each of the first end and the second end, each fastener pad defining a fastener hole, the first end comprising a first shoulder and a tongue and the second end comprising a second shoulder and a groove, the first shoulder defining a first bottom surface and the second shoulder defining a second bottom surface, the first bottom surface being non-parallel and non-coplanar with the second bottom surface with the pipe joint assembly in an assembled and untightened condition, the first bottom surface being substantially parallel and non-coplanar with the second bottom surface with the pipe joint assembly in an assembled and tightened condition, each tongue protruding circumferentially from each first end, an inner surface of each tongue configured to contact the annular gasket, each groove defined circumferentially in each second end, each groove sized to accept the tongue of a one of the pair of segments; and
a pair of fasteners, each fastener engaging a one of the fastener holes of the pair of segments, each fastener configured to deflect each segment around the first pipe element and the second pipe element into the assembled and tightened condition.

Abstract
A pipe joint assembly including a first pipe element, a second pipe element, a pair of segments, each segment defining a first end and a second end, each first end comprising a tongue and each second end comprising a groove, each groove defining a groove shoulder surface, the tongue of the one segment defining a tongue outer surface, the tongue outer surface of the tongue of the one segment angled at a non-zero angle relative to the groove shoulder surface in an assembled and untightened position, the tongue outer surface of the tongue positioned parallel and flush to the groove shoulder surface of the groove of the second segment in an assembled and tightened condition; and a pair of fasteners configured to deflect each segment around the first pipe element and the second pipe element in the assembled and tightened condition.

8. A coupling comprising:
-
a segment, the segment being approximately semi-circular and defining a first end and a second end, the segment comprising a first fastener pad protruding proximate to the first end and a second fastener pad protruding proximate to the second end, the first fastener pad defining a first fastener hole and the second fastener pad defining a second fastener hole, the first end comprising a first shoulder and a first tongue, the second end comprising a second shoulder and a first groove, the first shoulder defining a first bottom surface, the second shoulder defining a second bottom surface, the first bottom surface being non-parallel and non-coplanar with the second bottom surface with the coupling in an undeformed condition, the first bottom surface being substantially parallel and non-coplanar with the second bottom surface with the coupling in a deformed condition, the first tongue protruding circumferentially from the first end, the first groove defined circumferentially in the second end, the first groove sized to accept a second tongue of a second segment; and a pair of fasteners, each fastener engaging a different one of the first fastener hole and the second fastener hole of the segment. - View Dependent Claims (9, 10, 11, 12, 13, 14)
