Abstract
Abstract Tubular conduits are swivelly coupled to each other by axially overlapping coupling parts that are axially locked by a single piece annular coupling spring retained in position by an outer operating sleeve. The coupling spring has radially outer segments received in a recess of the operating sleeve from which connecting loops extend radially through openings in a supporting cage projecting from the female coupling part. The radially inner portions of the connecting loops engage the male coupling part in axially spaced relation to the outer segments.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
161 words
In combination with a pair of axially overlapping members adapted to be rotatable relative to each other about a common axis, a coupling assembly comprising an annular spring element, spring retaining means projecting from one of said members in surrounding relation to the other of the members holding the spring element in an elastically undeformed condition, a hook formation projecting radially outwardly from the other of said members axially between the spring element and a shoulder formed axially inwardly from said spring retaining means on said one of the members when the members are coupled together, an operating sleeve having an internal recess receiving said spring element in the undeformed condition thereof, means connected to both of said members jointly supporting the operating sleeve in said coupled position, and means limiting axial displacement of the operating sleeve in one direction against the bias of said spring element from a coupling position in which said spring element is received in the recess.
Claim 2
Dependent Claim
161 words
In combination with a pair of axially overlapping members adapted to be rotatable relative to each other about a common axis, a coupling assembly comprising an annular spring element, spring retaining means projecting from one of said members in surrounding relation to the other of the members holding the spring element in an elastically undeformed condition, a hook formation projecting radially outwardly from the other of said members axially between the spring element and a shoulder formed axially inwardly from said spring retaining means on said one of the members when the members are coupled together, an operating sleeve having an internal recess receiving said spring element in the undeformed condition thereof, means connected to both of said members jointly supporting the operating sleeve in said coupled position, and means limiting axial displacement of the operating sleeve in one direction against the bias of said spring element from a coupling position in which said spring element is received in the recess.
Claim 3
Dependent Claim
68 words
The combination of claim 1 wherein said spring retaining means includes an annular supporting cage having circumferentially spaced openings through which the spring element projects radially outwardly into the recess of the operating sleeve and radially inwardly into engagement with the hook formation and fulcrum means on the cage for rendering the spring element operative to transmit force between the other of the members and the operating sleeve.
Claim 4
Dependent Claim
30 words
The combination of claim 2 wherein said limiting means comprises an annular stop formation connected to said one of the members abutting the operating sleeve in the coupling position thereof.
Claim 5
Dependent Claim
55 words
The combination of claim 3 wherein said sleeve supporting means includes a radial projection connected to the other of the members in abutment with the spring retaining means and external slide bearing surfaces formed on the radial projection and the spring retaining means slidably supporting the operating sleeve thereon in coaxial relation to said members.
Claim 6
Dependent Claim
79 words
The combination of claim 4 wherein said spring element includes radially outer segments received within the recess of the operating sleeve, radially inner portions axially spaced from said outer segments in circumferentially staggered relation thereto, and connecting sections extending between the outer segments and the radially inner portions to define a generally conical configuration, said spring element being deformable in axial and radial directions by the operating sleeve and the hook formation during coupling and uncoupling of the members.
Claim 7
Dependent Claim
30 words
The combination of claim 1 wherein said limiting means comprises an annular stop formation connected to said one of the members abutting the operating sleeve in the coupling position thereof.
Claim 8
Dependent Claim
55 words
The combination of claim 1 wherein said sleeve supporting means includes a radial projection connected to the other of the members in abutment with the spring retaining means and external slide bearing surfaces formed on the radial projection and the spring retaining means slidably supporting the operating sleeve thereon in coaxial relation to said members.
Claim 9
Dependent Claim
79 words
The combination of claim 1 wherein said spring element includes radially outer segments received within the recess of the operating sleeve, radially inner portions axially spaced from said outer segments in circumferentially staggered relation thereto, and connecting sections extending between the outer segments and the radially inner portions to define a generally conical configuration, said spring element being deformable in axial and radial directions by the operating sleeve and the hook formation during coupling and uncoupling of the members.
