The present invention relates to a ring member of a ring-type universal joint utilized for transferring rotary motion from a first shaft to a second shaft. The ring member includes a plurality of circumferentially spaced openings for receiving outwardly extending torque transfer elements associated with the first and second shafts. One or more of these openings are separable to facilitate connection of the first and second shafts. In this regard, the separable bores are formed partially within the ring member and partially within a retaining member interconnectable to the ring member. This allows for disposing a torque transfer element within a portion of the bore formed on the ring member and then interconnecting the retainer over that element. In one embodiment, the, retaining members for first and second opposing pairs of bores interconnect to opposite sides of the ring member allowing individual interconnection of the shafts to the ring.

1. A ring apparatus to interconnect first and second shafts for rotation, comprising:a continuous annular member, said member at least partially defining first and second pairs of opposing radial bores, wherein a first axis is defined by said first pair of opposing radial bores and a second axis is defined by said second pair of opposing radial bores are transverse; a first retainer interconnectable to a first side of said annular member, wherein said first retainer and said annular member in combination define one bore of said first pair of opposing radial bores; a second retainer interconnectable to a second side of said annular member, wherein said second retainer and said annular member in combination define one bore of said second pair of opposing radial bores wherein each said retainer forms at least one interface surface with said annular member and wherein for each said interface surface at least one projection formed on one of said retainer and said annular member extends across said interface surface into a mating recess formed within the other of said retainer and annular member. 2. The apparatus of claim 1, wherein a second bore of at least one of said first and second pairs of opposing radial bores is entirely defined by said annular member.3. The apparatus of claim 1, further comprising:third and fourth retainers interconnectable to said first and second sides of said annular member, respectively, wherein said third and fourth retainers in combination with said annular member define a second bore of each of said first and second pairs of opposing radial bores, respectively. 4. The apparatus of claim 1, wherein said first and second axes are perpendicular.5. The apparatus of claim 1, wherein said first and second axes are co-planar.6. The apparatus of claim 1, wherein each said bore is substantially cylindrical for receiving a cylindrical element.7. The apparatus of claim 6, wherein each said cylindrical bore has a reduced diameter around at least a portion of its circumference at a first position along its length.8. The apparatus of claim 7, wherein each said cylindrical bore contains circumferential recess, said recess sized to receive a retaining element.9. The apparatus of claim 7, wherein each said reduced diameter around at least a portion of said cylindrical bore at an outward edge of said bore as measured from the center of said annular member.10. The apparatus of claim 1, wherein each said retainer forms up to half of each said radial bore.11. The apparatus of claim 10, wherein each said retainer forms at least one interface surface with said annular member.12. The apparatus of claim 11, wherein said interface surfaces is at least partially transverse to a plane of rotation of said annular member.13. The apparatus of claims 1, wherein said at least one projection and mating recess are operative to align said retainer and said annular member for interconnection.14. The apparatus of claim 1, further comprising:a mechanical fastener for interconnecting said retainer to said annular member. 15. The apparatus of claim 1, wherein said mechanical fastener is selectively removable allowing said retainer to be selectively disconnected from said annular member.16. A ring apparatus to interconnect first and second shafts for rotation, comprising:a continuous annular member, said member at least partially defining first and second pairs of opposing radial bores, wherein said first and second pairs of opposing radial bores define first and second axes substantially common plane; a plurality of retainers interconnectable to said annular member, wherein each said retainer forms a first portion of one of said bores and said annular member forms a second portion of said bore; a first abutting surface formed on each said retainer; and a second abutting surface formed on said annular member, wherein said first and second abutting surfaces abut upon interconnection of each said retainer to said annular member to advancement of said each retainer in a direction perpendicular to said common plane. 17. The apparatus of claim 16, wherein at least a portion of an interface surface between said retainer and said annular member is transverse to said common plane.18. The apparatus of claim 16, further comprising:at least one projection integrally formed on one of said retainer and said annular member and a mating recess integrally formed within the other of said retainer and said annular member. 19. The apparatus of claim 18, wherein said at least one projection extends across an interface surface between said retainer and said annular member and is received within said recess when said retainer is interconnected to said annular member.20. The apparatus of claim 16, wherein both bores of one of said first and second pairs of opposing radial bores are entirely defined by said annular member.21. The apparatus of claim 16, wherein both bores of one of said first and second pairs of opposing radial bores include an interconnectable retainer.22. The apparatus of claim 16, further comprising:first and second retainers associated with said first and second pairs of opposing radial bores, wherein said first and second retainers are interconnectable to opposite sides of said annular member. 23. The apparatus of claim 16, wherein said means to limit advancement further comprises a first abutting surface associated with said retainer and a second abutting surface associated with said annular ring, wherein said first and second abutting surfaces abut to prevent advancement of said retainer beyond a predetermined position relative to said annular member.24. A ring apparatus to interconnect first and second shafts for rotation, comprising:a continuous annular member, said member at least partially defining first and second pairs of opposing radial bores; and a retainer interconnectable to said annular member, wherein said retainer forms a first portion of one of said bores and said annular member forms a second portion of said bore; at least one projection integrally formed on one of said retainer and said annular member; and a mating recess integrally formed within the other of said retainer and said annular member, wherein said projection and recess engage to prevent advancement of said retainer beyond a predetermined position relative to said second portion of said bore defined by said annular member. 25. The apparatus of claim 24, wherein each said bore is defined in part by a separate retainer interconnectable to said annular member.26. The apparatus of claim 24, wherein said at least one projection extends across an interface surface between said retainer and said annular member and is received within said recess when said retainer is interconnected to said annular member.
