Abstract

Claims (32)

1. A method of mounting a support assembly within a non-T-bar ceiling support structure, the support assembly configured to secure a flexible fire sprinkler fitting to a T-bar ceiling support structure, the non-T-bar ceiling support structure including parallel, spaced beams, the method including:

positioning an adaptor such that the adaptor rests on each beam of a pair of adjacent beams, the adaptor configured to correspond to the configuration of a portion of a T-bar ceiling support structure, wherein the adaptor includes first and second long sides configured to be secured to each beam of the pair of adjacent beams, and first and second short sides configured to be secured to the support assembly, one end of each long side being joined by the first short side, and an opposed end of each long side being joined by the second short side such that the first and second long sides are parallel to each other and perpendicular to the first and second short sides, each short side having an L cross-sectional shape defined by a short side base portion, and a short side upright portion extending in a direction generally normal to the short side base portion, the one end and opposed end of each long side being supported on the short side base portion;

securing the adaptor to each beam of the pair of adjacent beams by fixing each long side to one of said beams; and

securing the support assembly to the adaptor.

2. The method of claim 1 , wherein the support assembly includes a leg extending transverse to the short sides, opposed ends of the leg include connection members, and a hub assembly supported on the leg includes a hub opening configured to receive the flexible fire sprinkler fitting;

wherein the step of securing the support assembly to the adaptor includes connecting the connection members to the short sides.

3. The method of claim 2 , wherein a free edge of the short side upright portion includes a protrusion that protrudes in a direction away from the short side base portion, and the respective connection members are configured to engage the protrusion when connecting to the short sides.

4. The method of claim 1 , wherein each long side has an L cross-sectional shape defined by a long side base portion, and a long side upright portion extending in a direction generally normal to the long side base portion, and wherein the spacing between the respective long side upright portions corresponds to the width of the support assembly.

5. The method of claim 1 , wherein the beams include hat channel members, each hat channel member including a channel base, sidewalls extending from opposed side edges of the channel base, and a flange extending along an edge of each sidewall in a direction generally parallel to the channel base, and wherein at least one of the first or second long sides is configured to secure to the flange.

6. The method of claim 1 , wherein the step of securing the support assembly to the adaptor includes:

providing vertical spacing between the support assembly and a ceiling panel secured to the ceiling support structure to permit a fire sprinkler head mounted to the fitting to be in a fully recessed or a semi recessed position relative to the ceiling panel.

7. A method of mounting a fire sprinkler support assembly for supporting a flexible fire sprinkler fitting within a ceiling structure comprising parallel, spaced beams, comprising:

providing the support assembly, the support assembly comprising an adaptor, a leg, and a hub assembly,

the adaptor including first and second long sides configured to be secured to each beam of a pair of adjacent beams, and first and second short sides configured to be secured to the support assembly, one end of each long side being joined by the first short side, and an opposed end of each long side being joined by the second short side such that the first and second long sides are parallel to each other and perpendicular to the first and second short sides, each short side having an L cross-sectional shape defined by a short side base portion, and a short side upright portion extending in a direction generally normal to the short side base portion, the one end and opposed end of each long side being supported on the short side base portion, the leg extending transverse to the short sides, opposed ends of the leg being connected to and supported on the short sides via connection members, and the hub assembly being supported on the leg and including a hub opening configured to receive the flexible fire sprinkler fitting;

positioning the adaptor such that the adaptor rests on each said beam of said pair of adjacent beams; and

securing the adaptor to each said beam of said pair of adjacent beams to secure the adapter to the support assembly.

8. The method of claim 7 , further comprising positioning each said connection member to straddle one of said short side upright portions.

9. The method of claim 7 , further comprising clamping each connection member to one of said short side upright portions.

10. The method of claim 7 , wherein at least one of said short side upright portions includes a protrusion, the method further comprising engaging at least one of the connection members with the protrusion.

11. The method of claim 7 , wherein the leg includes a central slot.

12. The method of claim 11 , wherein the leg includes lateral slots disposed between the central slot and lateral sides of the leg.

13. The method of claim 7 , wherein each long side has an L cross-sectional shape defined by a long side base portion, and a long side upright portion extending in a direction generally normal to the long side base portion, the method comprising spacing the respective long side upright portions apart from each other to correspond to a width of one of the connection members.

14. The method of claim 1 , wherein the hub assembly includes a primary support mounted to the leg, and a secondary support that is rotatable relative to the primary support between an open position and a closed position, the method further comprising:

configuring the hub assembly in the closed position so that cut outs formed in the primary support cooperate with cut outs formed in the secondary support to define the hub opening.

15. The method of claim 14 , wherein the hub assembly further includes a locking mechanism configured to selectively connect the primary support to the secondary support, and an adjustment mechanism disposed on the primary support, the method further comprising:

configuring the locking mechanism to secure the position of the portion of the flexible fire sprinkler fitting within the hub opening;

wherein the adjustment mechanism is separate from the locking mechanism.

16. The method of claim 7 , wherein each of the beams includes a hat channel member, and each hat channel member includes a channel base, sidewalls extending from opposed side edges of the channel base, and a flange extending along an edge of each sidewall in a direction generally parallel to the channel base, and wherein the step of securing the adaptor to each said beam of said pair of adjacent beams to secure the adapter to the support assembly further comprises securing at least one of the long sides to the flange.

17. The method of claim 7 , further comprising positioning the support assembly to provide sufficient height for mounting the flexible fire sprinkler fitting at a vertical location relative to the ceiling structure to permit one of semi-recessed or fully recessed position of a sprinkler head connected to the fitting.

18. The method of claim 7 , further comprising:

providing a flexible sprinkler assemblage, the flexible sprinkler assemblage including the flexible fire sprinkler fitting including a first end configured to connect to a flexible fluid supply line, and a second end configured to connect to a fire sprinkler head, and a flexible fluid supply line connected to the first end, and

positioning a portion of the flexible fire sprinkler fitting in the hub opening.
