Abstract

In one example embodiment, a bracket for a sprinkler fitting is provided having a first flange, a second flange connected to the first flange, and a mounting flange connected to at least one of the first and second flanges. The mounting flange may for example be substantially orthogonal to the first and second flanges. One of the first and second flanges has a preferably circular hole formed therethrough, and the other has a polygonal opening formed therethrough and aligned with the circular hole. An adapter having a polygonal end is inserted in the bracket such that the polygonal end aligns with the polygonal opening so as to limit rotation of the adapter with respect to the bracket, the adapter disposing a sprinkler coupled thereto with respect to a finished ceiling surface of a structure.

First claim

What is claimed is:

1. A bracket for a sprinkler fitting, comprising:
a first flange;
a second flange connected to the first flange, the first and second flanges being substantially parallel to each other;
a mounting flange connected to at least one of the first and second flanges; and
a hold-down bracket for retaining an adapter of the sprinkler fitting, the hold-down bracket being removably attached to the first flange,
wherein one of the first and second flanges comprises a first hole formed therethrough, and the other one of the first and second flanges comprises a polygonal opening formed therethrough and aligned with the first hole, the polygonal opening being non-circular, and aligning with a polygonal end of an adapter of the sprinkler fitting inserted in the bracket, such that rotation and vertical movement of the adapter is limited with respect to the bracket upon engagement of the polygonal opening with the adapter and attachment of the hold-down bracket, the adapter disposing a sprinkler coupled thereto with respect to a finished ceiling surface of a structure,
wherein the first flange and the second flange are both configured to receive and contact the sprinkler fitting.

2. A bracket according to claim 1 , wherein the first hole is circular.

3. A bracket according to claim 1 , wherein the first flange has a tab, and the hold-down bracket is removably attached to the tab of the first flange.

4. The bracket according to claim 3 , wherein the hold-down bracket is formed in a bent wishbone shape, and an upper u-shaped portion of the hold-down bracket is aligned with the first hole.

5. A bracket according to claim 1 , wherein the polygonal opening is hexagonal or octagonal.

6. A bracket according to claim 1 , wherein the mounting flange extends generally perpendicular to the first flange, and extends in a direction away from the second flange.

7. A bracket according to claim 1 , wherein the mounting flange extends generally perpendicular to the first flange, and extends in a direction toward the second flange.

8. A bracket according to claim 1 , wherein the mounting flange comprises at least two holes for attaching the mounting flange to an I-joist of the structure.

9. A bracket according to claim 1 , wherein the first flange extends from the mounting flange at a predetermined vertical distance measured from a bottom edge of a mounting flange, and is to align with a lower edge of a rafter/joist.

10. In combination, a bracket and a sprinkler fitting, the bracket comprising:
a first flange;
a second flange connected to the first flange, the first and second flanges being substantially parallel to each other;
a mounting flange connected to at least one of the first and second flanges; and
a hold-down bracket for retaining an adapter of the sprinkler fitting, the hold-down bracket being removably attached to the first flange,
wherein one of the first and second flanges comprises a first hole formed therethrough, and the other one of the first and second flanges comprises a polygonal opening formed therethrough and aligned with the first hole, the polygonal opening being non-circular, and aligning with a polygonal end of the sprinkler fitting inserted in the bracket, such that rotation and vertical movement of the fitting is limited with respect to the bracket upon engagement of the polygonal opening with the sprinkler fitting and attachment of the hold-down bracket, the fitting disposing a sprinkler coupled thereto with respect to a finished ceiling surface of a structure, and
wherein the first flange and the second flange are both configured to receive and contact the sprinkler fitting.

11. The combination of claim 10 , wherein the first and second flanges are spaced apart a predetermined distance to accommodate a portion of the fitting positioned therebetween.

12. The combination of claim 11 , wherein a threaded end of the sprinkler is inserted through the circular hole into the fitting to limit vertical motion of the fitting.

13. The combination of claim 12 , further comprising a locknut threaded onto the threads of the sprinkler before the sprinkler is threaded to the fitting.

14. The combination of claim 11 , wherein the fitting is a CPVC (chlorinated polyvinyl chloride) to NPT (National Piper Tapered Thread) adapter.

15. The combination of claim 14 , wherein the adapter is a 1 inch CPVC to ½ inch NPT adapter or a ¾ inch CPVC to ½ inch NPT adapter.
