Abstract

A fire exposure protection sprinkler assembly includes a fluid supply line configured to provide fire exposure protection fluid and a fire exposure protection sprinkler. The fire exposure protection sprinkler includes a body coupled to the fluid supply line and configured to receive the fire exposure protection fluid, a sealing assembly configured to unseal in response to a fire such that fire exposure protection fluid may flow, a housing having a pair of legs arranged opposite the housing of each other and having an aperture, and a deflection assembly having a pair of guide pins coupled to a deflector and the housing and disposed within each of the apertures of the legs, wherein the deflection assembly is configured to extend from the housing, wherein the deflection assembly is configured to receive the flow of the fire exposure protection fluid while extending from the housing.

First claim

What is claimed is:

1. A sprinkler, comprising:
a body defining an opening that extends through the body along an axis;
a sealing assembly that seals the opening;
a housing coupled with the body, the housing comprising a plurality of apertures;
a plurality of guide pins, each guide pin coupled with a respective aperture of the plurality of apertures, each guide pin defines an oblique angle in a same direction relative to the axis; and
a deflector coupled with the plurality of guide pins and angled relative to the axis, the deflector to move from a first position to a second position responsive to the sealing assembly moving out of the opening to allow fluid through the opening to contact the deflector.

2. The sprinkler of claim 1 , comprising:
the oblique angle is between one degree and fifteen degrees.

3. The sprinkler of claim 1 , comprising:
the body includes a hexagonal portion contacting the housing between the housing and the body.

4. The sprinkler of claim 1 , comprising:
a footprint of the housing is within a footprint of the body.

5. The sprinkler of claim 1 , comprising:
the housing comprises a pair of legs, each leg of the pair of legs defining one of the apertures of the plurality of apertures, and a foot extending toward the axis from each leg.

6. The sprinkler of claim 1 , comprising:
the guide pins are not parallel with the axis.

7. The sprinkler of claim 1 , comprising:
the deflector is rigidly fixed with the plurality of guide pins.

8. The sprinkler of claim 1 , comprising:
an enclosure coupled with the body and positioned around at least a portion of the body.

9. The sprinkler of claim 1 , comprising:
a baffle coupled with the housing.

10. The sprinkler of claim 1 , comprising:
a portion of each guide pin of the plurality of guide pins defines a circumference greater than a circumference of the respective aperture.
