The Reliable Automatic Sprinkler Co. Inc.

A pendent fire protection sprinkler includes a sprinkler body having an inlet and an outlet that define a fluid passage and a sprinkler axis, a pair of frame arms that form a junction, a plug that seals the fluid passage, and a thermally responsive element provided between the plug and the junction, and configured to maintain the plug in the fluid passage prior to actuation of the sprinkler. A deflector, mounted to the junction, includes an annular, planar central portion extending along a plane that is perpendicular to the sprinkler axis, as well as a first angled portion, a second angled portion, a third angled portion, and a fourth angled portion, each angled portion extending outwardly from the planar central portion. Each of the first to fourth angled portions is bent away from the frame arms in the outlet direction from the plane of the planar central portion.

A fire protection nozzle includes (A) a body having a flow passage for a fluid that flows through the body in an output direction, frame arms having proximal ends connected to an outlet orifice and distal ends, the frame arms defining a frame arm plane, and a junction formed by the distal ends of the frame arms at a distance from the outlet orifice, the junction including a central bore and an outer wall, and (B) a planar member deflector configured to be mounted to the body. The deflector includes a planar member having a plurality of slots on a periphery of the planar member that define a plurality of tines. The plurality of slots include at least first slots, second slots, third slots, and fourth slots.

A method of protecting an occupancy, using a pendent fire protection sprinkler arrangement to be mounted in a ceiling, includes providing a plurality of pendent fire protection sprinklers, each having a sprinkler body having an inlet and an outlet defining a fluid passage and a sprinkler axis, and threads for connection to system piping of the occupancy. A pair of frame arms projects downwardly from the outlet and meet to form a junction. A plug seals a fluid passage, and a thermally responsive element between the plug and the junction retains the plug in the fluid passage. A deflector is mounted to the junction and includes a planar central portion extending outwardly from the sprinkler axis along a plane perpendicular to the sprinkler axis and first, second, third, and fourth angled portions bent away from the frame arms in the outlet direction from the plane of the planar central portion.

A deflector, mounted to the junction, includes an annular, planar central portion extending along a plane that is perpendicular to the sprinkler axis, as well as a first portion, a second portion, a third portion, and a fourth portion, each portion extending outwardly from the planar central portion. Each of the first and second portions has a rounded outermost peripheral edge. Each of the third and fourth portions has first, second, and third rectilinear outermost peripheral edges, a respective second rectilinear outermost peripheral edge being located between respective first and third rectilinear outermost peripheral edges, and the first and third rectilinear outermost peripheral edges being obtusely angled relative to the respective second rectilinear outermost edge.

A sprinkler guard, mountable to a fire protection sprinkler, includes a first plate with projections from the first plate in a first lateral direction orthogonal to a central axis, and a lower surface facing a downward direction opposite to the upward direction, a second plate with projections from the second plate in a second lateral direction opposite to the first, and a lower surface facing the downward direction, first and second legs having an upper end attached to the lower surface of the first plate, a middle portion extending in the downward direction, and a lower end, third and fourth legs having an upper end attached to the lower surface of the second plate, a middle portion extending in the downward direction, and a lower end. A circular ring is attached to the lower ends of the first to fourth legs, and the legs are spaced about the circular ring.

A fire protection nozzle includes a body having inlet and outlet orifices defining a body axis, and a flow passage for a fluid that flows through the body in an output direction, frame arms having proximal ends connected to the outlet orifice and distal ends, the frame arms defining a frame arm plane, a junction formed by the frame arms distal ends at a distance from the outlet orifice, the junction including a central bore and an outer wall, and body deflectors extending from each of the frame arms in the frame arm plane at an angle relative to the body axis. Each of the body deflectors has an inner planar surface facing the junction. The nozzle also includes a planar member deflector to be mounted to the nozzle body. The deflector includes a planar member having a plurality of slots on a periphery that define a plurality of tines.

A sprinkler guard includes at least one plate centered relative to a central axis of the sprinkler guard. A plurality of legs includes first and second legs that are attached to one plate, and third and fourth legs that are attached to another plate. A circular ring is attached to lower ends of the first to fourth legs, a center of the circular ring coinciding with the central axis, and the first to fourth legs being spaced apart about the circumference of the circular ring. First and second arms are attached to the first and second legs, respectively. In addition, a cross bar can be attached to the circular ring and extend across a diameter of the circular ring.
