Abstract

A sprinkler includes a connector, a body, at least one pin, and a deflector. The connector extends between an inlet end and an outlet end. The body includes a pin wall extending from the outlet end of the connector. The pin wall defines at least one pin receiver. The body wall extends from the pin wall. The pin wall and the body wall define a chamber. The at least one pin is fixed with the at least one pin receiver. The deflector is coupled with the at least one pin to move within the chamber along the at least one pin responsive to a trigger condition from an undeployed state to a deployed state.

A sprinkler, comprising: a connector extending between an inlet end and an outlet end; a body comprising: a pin wall integral with and extending from the outlet end of the connector, the pin wall defining at least one pin receiver; and a body wall extending from the pin wall, the pin wall and the body wall define a chamber; at least one pin fixed with the at least one pin receiver; and a deflector comprising an aperture in which the at least one pin is disposed to allow the deflector move within the chamber along the at least one pin responsive to a trigger condition from an undeployed state to a deployed state.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS The present application claims the benefit of and priority to U.S. Provisional Application No. 63/045,306, filed Jun. 29, 2020, the disclosure of which is incorporated herein by reference in its entirety. BACKGROUND Fire protection systems can use sprinklers to output fluids to address fire conditions. The sprinklers can be mounted in various locations in a building, and can be mounted in a concealed configuration. SUMMARY At least one aspect relates to a sprinkler. The sprinkler can include a connector, a body, at least one pin, and a deflector. The connector extends between an inlet end and an outlet end. The body includes a pin wall extending from the outlet end of the connector. The pin wall defines at least one pin receiver. The body wall extends from the pin wall. The pin wall and the body wall define a chamber. The at least one pin is fixed with the at least one pin receiver. The deflector is coupled with the at least one pin to move within the chamber along the at least one pin responsive to a trigger condition from an undeployed state to a deployed state. At least one aspect relates to a sprinkler system. The sprinkler system can include one or more pipes coupled with a fluid supply and a sprinkler. The sprinkler includes a connector, a pin wall, at least one pin, and a deflector. The connector extends between an inlet end and an outlet end. The pin wall extends from the outlet end of the connector and defines at least one pin receiver. The at least one pin is fixed with the at least one pin receiver. The deflector is coupled with the at least one pin to move along the at least one pin responsive to a trigger condition from an undeployed state to a deployed state. At least one aspect relates to a deflector assembly. The deflector assembly can include a plurality of pins that engage with a sprinkler and a deflector. The deflector includes a plurality of deflector arms that extend outward from a longitudinal axis. Each deflector arm of the plurality of deflector arms defines a receiver coupled with a respective pin of the plurality of pins. The plurality of deflector arms move along the plurality of pins and parallel with the longitudinal axis responsive to a trigger condition from an undeployed state to a deployed state. Each pin of the plurality of pins includes a flange to restrict movement of a respective deflector arm of the plurality of deflector arms beyond the deployed state. These and other aspects and implementations are discussed in detail below. The foregoing information and the following detailed description include illustrative examples of various aspects and implementations, and provide an overview or framework for understanding the nature and character of the claimed aspects and implementations. The drawings provide illustration and a further understanding of the various aspects and implementations, and are incorporated in and constitute a part of this specification. BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings are not intended to be drawn to scale. Like reference numbers and designations in the various drawings indicate like elements. For purposes of clarity, not every component can be labeled in every drawing. In the drawings: FIG. 1 is a schematic diagram of an example of a sprinkler system. FIG. 2 is a section view of an example of a sprinkler of a sprinkler system. DETAILED DESCRIPTION Following below are more detailed descriptions of various concepts related to, and implementations of sprinkler systems and methods. Fire sprinklers can be used to address fire conditions by outputting fire suppression agents, such as water or other fire suppression fluids, to address the fire. The fire sprinklers (or the fire suppression agent delivered to the fire sprinklers) can be controlled to selectively output fire suppression agents. The various concepts introduced above and discussed in greater detail below can be implemented in any of numerous ways, including in sprinkler systems that implement concealed sprinklers (e.g., sprinklers installed in a manner that can reduce the physical extension and visibility of the sprinkler beyond the walls of the building) and non-concealed sprinklers. Sprinklers can be installed by connecting the sprinklers with piping that is connected with a fluid supply. For example, in buildings, including residential buildings, sprinklers may be installed so that a body of the sprinkler is positioned in a particular location relative to a wall or ceiling. Locating the sprinkler properly during installation may be limited by factors such as the position of the piping relative to the wall or ceiling and a target location for a deflector of the sprinkler during operation. Systems and methods in accordance with the present disclosure can use a sprinkler that includes a deflector that moves along a plurality of pins in a body of the sprinkler from a first, undeployed position to a second, deployed position. This can
