Hooked pipe coupling
A hooked pipe coupling includes a first pipe coupling segment comprising a first arcuate body portion defining a first end and a second end opposite the first end, a first hook extending from the first end, and a first fastener lug extending from the second end, the first arcuate body portion defining a first sloped ledge surface; and a second pipe coupling segment comprising a second arcuate body portion defining a third end and a fourth end opposite the third end, a second hook extending from the third end, and a second fastener lug extending from the fourth end, the second arcuate body portion defining a second sloped ledge surface; wherein the first sloped ledge surface presses against the second sloped ledge surface in a tightened configuration of the hooked pipe coupling to prevent axial movement of the first pipe coupling segment relative to the second pipe coupling segment.
1 . A hooked pipe coupling comprising:
a first pipe coupling segment comprising a first arcuate body portion defining a first end and a second end opposite the first end, a first hook extending from the first end, and a first fastener lug extending from the second end, the first arcuate body portion defining a first sloped ledge surface; and
a second pipe coupling segment comprising a second arcuate body portion defining a third end and a fourth end opposite the third end, a second hook extending from the third end, and a second fastener lug extending from the fourth end, the second arcuate body portion defining a second sloped ledge surface;
wherein the first sloped ledge surface presses against the second sloped ledge surface in a tightened configuration of the hooked pipe coupling, wherein:
the first pipe coupling segment defines a first axial side and a second axial side opposite the first axial side;
the second pipe coupling segment defines a third axial side aligned with the first axial side and a fourth axial side opposite the third axial side and aligned with the second axial side;
the first sloped ledge surface is sloped downward and away from the first fastener lug in a direction extending from the first axial side to the second axial side;
the second sloped ledge surface is sloped upward and away from the second fastener lug in a direction extending from the fourth axial side to the third axial side;
the first hook defines a first shank portion and a first bend portion, the first shank portion extends in a substantially radially outward direction from the first arcuate body portion, and the first bend portion extends from the first shank portion toward the first axial side; and
the second hook defines a second shank portion and a second bend portion, the second shank portion extends in a substantially radially outward direction from the second arcuate body portion, and the second bend portion extends from the second shank portion toward the fourth axial side.
2 . The hooked pipe coupling of claim 1 , wherein each of the first sloped ledge surface and the second sloped ledge surface are substantially planar.
3 . The hooked pipe coupling of claim 2 , wherein, in a relaxed configuration of the hooked pipe coupling, the first sloped ledge surface is spaced apart from the second sloped ledge surface.
4 . The hooked pipe coupling of claim 3 , wherein a fastener extends through each of the first fastener lug and the second fastener lug, and wherein the fastener is tightened to reconfigure the hooked pipe coupling from the relaxed configuration to the tightened configuration.
5 . The hooked pipe coupling of claim 4 , wherein the fastener comprises a threaded bolt and a threaded nut rotatably mounted on the threaded bolt.
6 . The hooked pipe coupling of claim 1 , wherein the first bend portion defines a first engagement surface, and wherein the second bend portion defines a second engagement surface confronting the first engagement surface.
7 . The hooked pipe coupling of claim 6 , wherein:
the first bend portion defines a first projection extending from the first engagement surface;
the second bend portion defines a second projection extending from the second engagement surface; and
the first projection is configured to engage the second projection to further prevent axial movement of the first pipe coupling segment relative to the second pipe coupling segment.
8 . The hooked pipe coupling of claim 6 , wherein the first engagement surface defines a first sloped portion angled rearwardly towards the first shank portion, and wherein the second engagement surface defines a second sloped portion angled forwardly towards the second shank portion.
