Abstract

Systems and methods described herein are directed to a sprinkler to provide fire protection. The sprinkler system can include a deflector portion, a head portion, a thermal trigger portion, a trigger seat, or a tubular outer structure. The tubular outer structure can define an internal water flow channel. The water flow channel can extend along a longitudinal axis between an inlet and an outlet. The trigger seat can include a tubular exterior. The tubular exterior can be coupled with the tubular outer structure. The trigger seat can include a component. The component can occlude a flow of fluid through the dry pendent sprinkler assembly. The component can maintain the thermal trigger portion in position. At least one portion of the tubular exterior of the trigger seat can protrude into the water flow channel at an angle towards the longitudinal axis.

First claim

The invention claimed is:

1. A sprinkler assembly, comprising:
a structure defining a channel extending between an inlet and an outlet along a longitudinal axis;
a head portion coupled with the structure;
a deflector coupled with the head portion;
a trigger seat coupled with the outlet, the trigger seat comprising:
an exterior extending in a longitudinal direction between a first end and a second end, the exterior having at least three apertures disposed circumferentially about the exterior; and
a surface extending inward from the second end of the exterior towards a center of the channel; and

a thermal trigger positioned between the surface and the deflector.

2. The sprinkler assembly of claim 1 , comprising:
the surface comprises at least one of a hole, an insert, or a groove to maintain the thermal trigger in position.

3. The sprinkler assembly of claim 1 , comprising:
the surface comprises at least one of a hole, an insert, or a groove to maintain the thermal trigger in position, the at least one of the hole, the insert, or the groove protrudes from the surface.

4. The sprinkler assembly of claim 1 , comprising:
the longitudinal axis passes through a hole defined in the surface of the trigger seat, the thermal trigger, and the deflector.

5. The sprinkler assembly of claim 1 , comprising:
the thermal trigger comprises a glass bulb.

6. The sprinkler assembly of claim 1 , comprising:
the trigger seat is coupled with the outlet such that the channel extends into the trigger seat to the surface.

7. The sprinkler assembly of claim 1 , comprising:
the surface defines at least one hole disposed inward from the exterior of the trigger seat and outward from where the thermal trigger couples with the surface.

8. The sprinkler assembly of claim 1 , comprising:
the exterior of the trigger seat is tubular.

9. The sprinkler assembly of claim 1 , comprising:
the sprinkler assembly is a dry pendent sprinkler assembly.

10. The sprinkler assembly of claim 1 , comprising:
the at least three apertures include a same size and shape.

11. The sprinkler assembly of claim 1 , comprising:
the at least three apertures differ in at least one of size or shape.

12. A dry pendent sprinkler assembly, comprising:
an outer structure forming a channel extending along a longitudinal axis to an outlet;
a head portion extending from the outer structure at least partially outward from the longitudinal axis;
a deflector coupled to the head portion at an opposite end of the head portion from the outer structure;
a trigger seat in the outlet to occlude the channel, the trigger seat comprising an exterior extending in a longitudinal direction between a first end and a second end, the exterior having at least three apertures disposed circumferentially about the exterior and a surface extending inward from the second end of the exterior towards a center of the channel; and
a thermal trigger coupled with the surface and positioned between the surface and the deflector.

13. The dry pendent sprinkler assembly of claim 12 , comprising:
the surface comprises a component to maintain the thermal trigger in position, the component comprising at least one of a hole, an insert, or a groove.

14. The dry pendent sprinkler assembly of claim 12 , comprising:
the surface comprises a component protruding from the surface to maintain the thermal trigger in position, the component comprising at least one of a hole, an insert, or a groove.

15. The dry pendent sprinkler assembly of claim 12 , comprising:
the longitudinal axis passes through a hole defined in the surface of the trigger seat, the thermal trigger, and the deflector.

16. The dry pendent sprinkler assembly of claim 12 , comprising:
the thermal trigger comprises a glass bulb.

17. The dry pendent sprinkler assembly of claim 12 , comprising:
the trigger seat is coupled with the outlet such that the channel extends into the trigger seat to the surface.

18. The dry pendent sprinkler assembly of claim 12 , comprising:
the exterior of the trigger seat is tubular.

19. The dry pendent sprinkler assembly of claim 12 , comprising:
the at least three apertures include a same size and shape.

20. The dry pendent sprinkler assembly of claim 12 , comprising:
the at least three apertures differ in at least one of size or shape.
