Abstract

A sprinkler button includes a body and a wall extending from the body. The body includes a ridge and one or more cavities defined by the ridge and extending into the body. The body defines a hollow chamber on an opposite side of the body from the one or more cavities. The wall includes one or more tabs.

First claim

What is claimed is:

1 . A sprinkler button, comprising:
a body comprising a ridge and a surface that asymmetrically defines a plurality of cavities to be on one half of the surface and extending into the body, the body defining a hollow chamber on an opposite side of the body from the plurality of cavities; and a wall extending from the body, the wall includes one or more tabs.

2 . The sprinkler button of claim 1 , comprising:
the surface is spherical.

3 . The sprinkler button of claim 1 , comprising:
the body is made of copper, stainless steel, or phosphor bronze.

4 . The sprinkler button of claim 1 , comprising:
the body and the wall are monolithic.

5 . The sprinkler button of claim 1 , comprising:
the body comprises a spherical shell having a thickness greater than 0.02 inches and less than 0.035 inches.

6 . The sprinkler button of claim 1 , comprising:
a ratio of a height of the wall to a height by which the one or more tabs extend beyond the wall is greater than 1:2 and less than 2:1.

7 . The sprinkler button of claim 1 , comprising:
an angle of the one or more plurality of cavities relative to the wall is greater than 30 degrees and less than 40 degrees.

8 . The sprinkler button of claim 1 , comprising:
the wall includes a plurality of wall portions that define at least one gap between adjacent wall portions of the plurality of wall portions.

9 . The sprinkler button of claim 1 , comprising:
the one or more tabs form an angle by which the one or more tabs extend around an insert that is less than ninety degrees.

10 . A sprinkler, comprising:
a sprinkler body comprising an internal passageway that extends from an inlet to an orifice; a sprinkler button, comprising:
a button body comprising a surface defining a ridge and asymmetrically defining a plurality of cavities to be on one half of the surface and extending into the button body, the button body defining a hollow chamber on an opposite side of the body from the plurality of cavities; and
a wall extending from the button body, the wall comprises one or more tabs;
a thermal trigger that applies a load to the sprinkler button; and
a frame that extends from the sprinkler body around the thermal trigger.

11 . The sprinkler of claim 10 , comprising:
the thermal trigger is triggered responsive to a fire condition to remove the load from the sprinkler button so that pressure from fluid in the internal passageway ejects the sprinkler button.

12 . The sprinkler of claim 10 , comprising:
the surface defines the plurality of cavities adjacent to the ridge.

13 . The sprinkler of claim 10 , comprising:
the button body is made of at least one of copper, stainless steel, phosphor bronze, nickel, titanium, and chromium.

14 . The sprinkler of claim 10 , comprising:
the button body comprises a spherical shell having a thickness greater than 0.02 inches and less than 0.035 inches.

15 . The sprinkler of claim 10 , comprising:
a ratio of a height of the wall to a height by which the one or more tabs extend beyond the wall is greater than 1:2 and less than 2:1.

16 . The sprinkler of claim 10 , comprising:
the wall includes a plurality of wall portions that define at least one gap between adjacent wall portions of the plurality of wall portions; and the one or more tabs form an angle by which the one or more tabs extend around and receive an insert, the angle is less than ninety degrees.

17 . The sprinkler of claim 10 , comprising:
a deflector that receives fluid from the internal passageway responsive to actuation of the thermal trigger and outputs the fluid with a target spray pattern.

18 . A sprinkler button assembly, comprising:
a body comprising a ridge and a surface that asymmetrically defines a plurality of cavities to be on one half of the surface defined by the ridge and extending into the body, the body defining a hollow chamber on an opposite side of the body from the plurality of cavities; a wall extending from the body, the wall includes one or more tabs; and an insert secured by the one or more tabs.

19 . The sprinkler button of claim 1 , comprising:
an angle from the wall to a tangent of the plurality of cavities is greater than or equal to 20 degrees and less than or equal to 50 degrees.
