Abstract
Abstract An improved coupling ring is disclosed having unitary structure providing spring biased engagement between cooperating members. The coupling ring has a substantially cylindrical profile including, at one end, a rigid portion with inwardly directed helical latching grooves and, at the opposite end, an integral spring portion terminating with an inwardly directed annular flange. The members to be coupled are assembled with the coupling ring engaging a shoulder of one member by the flange and with the grooves receiving lugs fixed on the opposite member so that rotation of the ring will draw the members together and hold them together in a spring loaded condition.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
80 words
A resiliently loaded coupling ring comprising: a unitary, substantially cylindrical body of plastics material having a coupling first end and a spring second end; said coupling end having at least one internal helical groove; and said spring end having a plurality of rings interconnected by circumferentially spaced lands, the lands on each side of each ring being circumferentially offset, and the endmost of said rings having an inner diameter less than the remaining rings to form an annular latching shoulder.
Claim 2
Dependent Claim
80 words
A resiliently loaded coupling ring comprising: a unitary, substantially cylindrical body of plastics material having a coupling first end and a spring second end; said coupling end having at least one internal helical groove; and said spring end having a plurality of rings interconnected by circumferentially spaced lands, the lands on each side of each ring being circumferentially offset, and the endmost of said rings having an inner diameter less than the remaining rings to form an annular latching shoulder.
Claim 3
Dependent Claim
17 words
The coupling ring according to claim 1 further comprising: outwardly directed gripping means on said coupling portion.
Claim 4
Dependent Claim
23 words
The coupling ring according to claim 1 wherein each said helical groove terminates with an aperture through a sidewall of said coupling portion.
Claim 5
Dependent Claim
156 words
A coupling ring for holding a pair of mating members together in a resiliently loaded condition, said ring comprising: a unitary body of plastics material having a substantially cylindrical profile defining a rigid first end and a resilient second end; said first end having at least one internal helical groove and external gripping means, said second end having a plurality of rings interconnected in pairs by circumferentially offset lands, the lands on each side of each said ring likewise being circumferentially offset, and the ring on the free end of said body having an inner diameter less than that of the other rings to form an internal annular latching shoulder, whereby said members are held together in a loaded condition by said shoulder engaging a corresponding shoulder on one mating member and said groove engaging corresponding means on the other member with rotational movement of said ring drawing said members together while stretching said resilient end.
Claim 6
Dependent Claim
156 words
A coupling ring for holding a pair of mating members together in a resiliently loaded condition, said ring comprising: a unitary body of plastics material having a substantially cylindrical profile defining a rigid first end and a resilient second end; said first end having at least one internal helical groove and external gripping means, said second end having a plurality of rings interconnected in pairs by circumferentially offset lands, the lands on each side of each said ring likewise being circumferentially offset, and the ring on the free end of said body having an inner diameter less than that of the other rings to form an internal annular latching shoulder, whereby said members are held together in a loaded condition by said shoulder engaging a corresponding shoulder on one mating member and said groove engaging corresponding means on the other member with rotational movement of said ring drawing said members together while stretching said resilient end.
