Abstract
A coupling for joining a first pipe segment to a second pipe segment that includes a first coupling segment and second coupling segment that has a first end, a second end, an outer surface, and an inner surface. Fastener openings are disposed on the first end and the second end, and the outer surface is contoured to define an arched shape that is higher towards an axial midpoint and lower towards the first end and the second end. The outer surface contains a band, a first skirt, and a second skirt on each side of the band. A seal groove is defined on the inner surface between two outer edges of the first coupling segment and a seal is disposed within the seal grove.

A coupling for joining a first pipe segment to a second pipe segment, comprising:
- a first coupling segment having a first end, a second end, an outer surface, and an inner surface, fastener openings are disposed on the first end and the second end, the outer surface is contoured to define an arched shape that is higher towards an axial midpoint and lower towards the first end and the second end, the outer surface contains a band and a first skirt and a second skirt on each side of the band, a seal groove is defined on the inner surface between two outer edges of the first coupling segment, a first rib is disposed between the seal groove and one outer edge, the first rib has a first end and a second end, a height of the first rib increases as the first rib progresses from the first end to a predetermined point on the first rib and decreases in height from the predetermined point to the second end, and a second rib is disposed between the seal groove and the opposed outer edge, a first transition portion provides a transition between the outer edge of the seal groove and the first rib and a second transition portion provides a transition between the outer edge of the seal groove and the second rib;
- a second coupling segment having a first end, a second end, an outer surface, and an inner surface, fastener openings are disposed on the first end and the second end, the outer surface is contoured to define an arched shape that is higher towards an axial midpoint and lower towards the first end and the second end, the outer surface contains a band and a first skirt and a second skirt on each side of the band, a seal groove is defined on the inner surface between two outer edges of the second coupling segment, a first rib is disposed between the seal groove and one outer edge, the first rib has a first end and a second end, a height of the first rib increases as the first rib progresses from the first end to a predetermined point on the first rib and decreases in height from the predetermined point to the second end, and a second rib is disposed between the seal groove and the opposed outer edge, a first transition portion provides a transition between the outer edge of the seal groove and the first rib and a second transition portion provides a transition between the outer edge of the seal groove and the second rib;
- and
- a seal.

A method for using a coupling to join a first pipe segment to a second pipe segment, comprising:
- providing a first coupling segment having a first end, a second end, an outer surface, and an inner surface, fastener openings are disposed on the first end and the second end, the outer surface is contoured to define an arched shape that is higher towards an axial midpoint and lower towards the first end and the second end, the outer surface contains a band and a first skirt and a second skirt on each side of the band, a seal groove is defined on the inner surface between two outer edges of the first coupling segment, a first rib with an upper edge is disposed between the seal groove and one outer edge and a second rib with an upper edge is disposed between the seal groove and the opposed outer edge, a first transition portion provides a transition between the one outer edge of the seal groove and the first rib and a second transition portion provides a transition between the opposed outer edge of the seal groove and the second rib;
- a second coupling segment having a first end, a second end, an outer surface, and an inner surface, fastener openings are disposed on the first end and the second end, the outer surface is contoured to define an arched shape that is higher towards an axial midpoint and lower towards the first end and the second end, the outer surface contains a band and a first skirt and a second skirt on each side of the band, a seal groove is defined on the inner surface between two outer edges of the second coupling segment, a first rib with an upper edge is disposed between the seal groove and one outer edge and a second rib with an upper edge is disposed between the seal groove and the opposed outer edge, a first transition portion provides a transition between the one outer edge of the seal groove and the first rib and a second transition portion provides a transition between the opposed outer edge of the seal groove and the second rib, wherein for the first coupling segment and the second coupling segment, the first rib and the second rib increase in height from a first end to a predetermined distance along the first rib and the second rib, and at the predetermined distance the first rib and the second rib decrease in height towards a second end;
- a seal;
- a first pipe segment;
- and
- a second pipe segment;
- placing an end of the second pipe segment between the first coupling segment and the second coupling segment;
