Adjustable sprinkler head positioning assembly

An adjustable fire-suppression sprinkler head positioning assembly comprising:

• a first conduit having a first conduit inlet and a first conduit outlet wherein a center line of the first conduit outlet is offset from and parallel to a center line of the first conduit inlet, said first conduit inlet and said first conduit outlet being oriented to direct fluid flow in the same direction, the first conduit inlet and the first conduit outlet being substantially circular in cross section and the centerlines of said first conduit inlet and of said first conduit outlet being offset in the radial direction by a distance equal to at least the diameter of said first conduit inlet, said first conduit inlet comprising an integral socket provided with female threads and said first conduit outlet comprising male threads, said integral socket provided with female threads adjustably securing said first conduit to a sprinkler drop line which is disposed behind a surface from which a sprinkler head is intended to protrude;
• a second conduit having a second conduit inlet and a second conduit outlet wherein a center line of the second conduit outlet is offset from and parallel to a center line of the second conduit inlet, said second conduit inlet and said second conduit outlet being oriented to direct fluid flow in the same direction, the second conduit inlet and the second conduit outlet being substantially circular in cross section and the centerlines of said second conduit inlet and said second conduit outlet being offset in the radial direction by a distance equal to at least the diameter of said second conduit inlet, said second conduit inlet comprising an integral socket provided with female threads, said male threads of said first conduit outlet being threadably receivable by said female threads of said integral socket of said second conduit inlet with said second conduit in a desired circumferential position relative to said first conduit while maintaining a fluid sealing relationship between said first conduit outlet and said second conduit inlet;
• means for receiving a sprinkler head, said means for receiving being disposed at said second conduit outlet and comprising male threads;
• said first conduit including said socket of said first conduit inlet and said male threads of said first conduit outlet being identical to said second conduit including said socket of said second conduit inlet and said male threads of said second conduit outlet, whereby the same tooling forms both the first conduit and the second conduit;
• whereby said means for receiving a sprinkler head may be variably positioned so as to be provided at a predetermined location along said surface from which a sprinkler head is intended to protrude.

• a second conduit having a second conduit inlet and a second conduit outlet wherein a center line of the second conduit outlet is offset from and parallel to a center line of the second conduit inlet, said second conduit inlet and said second conduit outlet being oriented to direct fluid flow in the same direction, the second conduit inlet and the second conduit outlet being substantially circular in cross section and the centerlines of said second conduit inlet and said second conduit outlet being offset in the radial direction by a distance equal to at least the diameter of said second conduit inlet, said second conduit inlet comprising a socket, said socket being integral with said second conduit, the smooth outer circumferential surface with a smooth outer contour of the first conduit outlet being receivable within said socket, said socket having a set screw for securing said second conduit in a desired circumferential position relative to said first conduit, said socket further comprising sealing means for preventing fluid leakage between said first conduit outlet and said second conduit inlet;
• means for receiving a sprinkler head, said means for receiving being disposed at said second conduit outlet, said means for receiving comprising male threads provided on said second conduit outlet;
• said first conduit including said socket of said first conduit inlet and said smooth outer circumferential surface with a smooth outer contour of said first conduit outlet being identical to said second conduit including said socket of said second conduit inlet and said second conduit outlet prior to receiving said male threads, whereby the same tooling forms both the first conduit and the second conduit;
• whereby said means for receiving a sprinkler head may be variably positioned so as to be provided at a predetermined location along said surface from which a sprinkler head is intended to protrude.
