Abstract
A sprinkler includes a body including an internal passageway extending from an inlet to an orifice. The body can be made of a composite material, such as a polymeric material. The sprinkler can include a first frame arm extending from the body, a second frame arm extending from the body, and a connector member connecting the first frame arm with the second frame arm.
Claims19
A sprinkler, comprising:
- a body comprising an internal passageway extending from an inlet to an orifice, the internal passageway defining a longitudinal axis;
- a first frame arm extending from the body;
- a second frame arm extending from the body, the first frame arm and the second frame arm each parallel with the longitudinal axis and comprising reinforcing fibers that are aligned within five degrees of parallel with the longitudinal axis;
- and
- a connector member that is monolithic with the first frame arm and the second frame arm, the connector member includes a first end that extends from the first frame arm, a second end that extends from the second frame arm, a sidewall that extends between the first end and the second end, a first guide pin channel that extends into the body towards the inlet, and a second guide pin channel that extends into the body towards the inlet, an arc length of the sidewall around the longitudinal axis is greater than sixty degrees and less than three hundred degrees.
