Abstract

A sprinkler system includes a fitting and a sprinkler. The fitting includes a hose and at least one adapter coupled with the hose. The at least one adapter includes a first engagement member and a receiver adjacent to the first engagement member. The receiver has a greater inner diameter than the first engagement member. The sprinkler includes a body, at least one flange extending from the body, and a second engagement member extending from the at least one flange.

First claim

What is claimed is:

1. A hose fitting, comprising:
a hose, comprising:
an inlet hose end;
a flange coupled with the inlet hose end;
a threaded member extending away from the flange;
an inlet gasket on the flange;
an outlet hose end; and
a hose portion disposed between the inlet hose end and the outlet hose end, the hose portion comprising at least one of a rubber material, a corrugated material, or a braided metal tubing;
an adapter, comprising:
an internal passageway between a first adapter end coupled with the outlet hose end and a second adapter end, the outlet hose end between the first adapter end and the inlet hose end, the second adapter end having a receiver to receive a sprinkler;
a threaded engagement member between the first adapter end and the second adapter end, the threaded engagement member having a lesser inner diameter than the receiver;
a gasket; and
a gasket chamber formed in the internal passageway between the first adapter end and the threaded engagement member, the gasket chamber having a holding portion to receive the gasket in an unloaded state and an expansion portion to receive a displaced portion of the gasket in a loaded state of the gasket from pressing of the gasket by the sprinkler; and

a second adapter identical to the adapter, wherein the second adapter is attached to the threaded member of the hose.

2. The hose fitting of claim 1 , comprising:
the gasket is an annular member.

3. The hose fitting of claim 1 , comprising:
the threaded engagement member comprises straight thread to enable hand tightening of the sprinkler with the adapter.

4. The hose fitting of claim 1 , comprising:
the adapter is integrally formed with the hose.

5. The hose fitting of claim 1 , comprising:
the adapter comprises a straight fitting, a reducer fitting, or an elbow fitting.

6. A fire protection sprinkler assembly, comprising:
a hose comprising an inlet hose end, a flange coupled with the inlet hose end, a threaded member extending from the flange, an inlet gasket on the flange; and an outlet hose end;
an adapter, comprising:
an internal passageway disposed between a first adapter end coupled with the outlet hose end and a second adapter end, the first adapter end between the outlet hose end and the second adapter end; and
a threaded engagement member between the first adapter end and the second adapter end;

a second adapter identical to the adapter, wherein the second adapter is attached to the threaded member of the hose; and
a sprinkler received in the second adapter end and coupled with the threaded engagement member.

7. The fire protection sprinkler assembly of claim 6 , comprising:
the hose comprises at least one of a rubber material, a corrugated material, or a braided metal tubing.

8. The fire protection sprinkler assembly of claim 6 , comprising:
a gasket in the adapter between the threaded engagement member and the first adapter end.

9. The fire protection sprinkler assembly of claim 6 , comprising:
a gasket chamber formed in the internal passageway between the first adapter end and the threaded engagement member; and
a gasket in the gasket chamber.

10. The fire protection sprinkler assembly of claim 6 , comprising:
the adapter is adjacent to the hose.

11. The fire protection sprinkler assembly of claim 6 , comprising:
the threaded engagement member comprises straight thread.

12. The fire protection sprinkler assembly of claim 6 , comprising:
a gasket chamber formed in the internal passageway between the first adapter end and the threaded engagement member, the gasket chamber having a holding portion to receive a gasket in an unloaded state and an expansion portion to receive a displaced portion of the gasket in a loaded state of the gasket from pressing of the gasket by the sprinkler.

13. A hose assembly, comprising:
a hose comprising at least one of a resilient material, a corrugated material, or a braided metal tubing, the hose comprising an inlet hose end, a shoulder coupled with the inlet hose end, a threaded member extending from the shoulder, an inlet gasket on the shoulder, and an outlet hose end opposite the inlet hose end;
an adapter, comprising:
a first end coupled with the outlet hose end, a second end forming a receiver configured to receive a sprinkler, the first end between the hose and the receiver, a threaded engagement member between the receiver and the first end, and a gasket chamber to receive a gasket between the first end and the threaded engagement member; and

a second adapter identical to the adapter, wherein the second adapter is attached to the threaded member of the hose.

14. The hose assembly of claim 13 , comprising:
the gasket chamber has a holding portion to receive the gasket in an unloaded state and an expansion portion to receive a displaced portion of the gasket in a loaded state of the gasket from pressing of the gasket by a sprinkler.

15. The hose assembly of claim 13 , comprising:
the threaded engagement member comprises straight thread.

16. The hose assembly of claim 13 , comprising:
the adapter is a straight fitting.
