Coupling ring, methods and applications
View Patent ↗A coupler for a load-bearing, non-signal-transmitting cable includes a body portion having integral first and second ends and an integral gate having a key entry region, wherein the body portion has a free space at least partially enclosed by an inner surface of the body portion and the gate. A complimentary coupling ring includes an integral perimetal body having a head section, a foot section, and two arm sections therebetween, wherein at least one of the arm sections has a key region, further wherein the key region consists of a solid, integral portion of the at least one arm section. A coupler/coupling ring assembly includes a coupler and a coupling ring that is removeably engageable with the coupler. The coupler/coupling ring assembly is particularly suited for interconnecting lengths of load-bearing, non-signal-transmitting cable, particularly suited for, but not limited to, undersea applications such as attaching a seismic data recording device to the coupler via the coupling ring.
1. A coupling ring, comprising:
an integral perimetal body in a form of a ring, characterized by a non-circular, continuous perimetal boundary having a head section, a foot section, and two non-parallelly opposed arm sections there between, wherein the head section has an interior curvature, C, and the foot section has an opposing interior curvature, c, where c>C, further wherein at least one of the arm sections has a key region disposed therein, further wherein the key region consists of a solid, integral portion of the at least one arm section, further wherein the coupling ring is attachable to a coupler component,
further comprising a non-keyed crossbar integrally connecting the two arm sections,
disposed between the key region and the foot section.
2. A coupling ring, comprising:
an integral perimetal body in the form of a ring, characterized by a non-circular, continuous perimetal boundary having a head section, a foot section, and two non-parallelly opposed arm sections there between, wherein the head section has an interior curvature, C, and the foot section has an opposing interior curvature, c, where c>C, further wherein at least one of the arm sections has a key region disposed therein, further wherein the key region consists of a solid, integral portion of the at least one arm section, wherein the coupling ring is attachable to a coupler component,
further comprising at least one nub that protrudes inwardly from an inner surface of the perimetal body, disposed between the key region and the foot section.
3. The coupling ring of claim 1 or 2 , wherein the key region has a thickness that is less than the thickness of any other portion of the arm.
4. The coupling ring of claim 1 or 2 , wherein the key region has a thickness that is greater than 0.015 in.
5. The coupling ring of claim 1 or 2 , wherein the key region is flat.
6. The coupling ring of claim 1 or 2 , wherein the key region is disposed closer to the foot section than to the head section.
7. The coupling ring of claim 1 or 2 , wherein the key region has two opposing walls in the shape of a V.
8. The coupling ring of claim 1 or 2 , wherein the key region is a pinched region of the arm having an arbitrary shape of reduced dimension.
