Abstract
Horizontal window fire protection sprinklers, systems and methods are provided. The sprinklers include a frame and a fluid deflection member including a window confronting surface having a planar portion and a concave portion. The sprinkler defines a maximum operating pressure of at least 100 psi. per sprinkler for adjacent sprinklers without cold soldering.
Claims25
A horizontal sidewall window sprinkler comprising:
- a frame including a body having an inlet, an outlet with an internal passageway extending between the inlet and the outlet along a sprinkler axis, the frame including a pair of frame arms spaced about a first plane bisecting the sprinkler frame, the frame arms being diametrically opposed about the outlet so as to be aligned in a second plane that intersects and is perpendicular to the first plane at the sprinkler axis, the frame arms extending axially from the body and converging toward the sprinkler axis to define a frame boss axially spaced from the outlet;
- and
- a fluid deflector coupled to the frame boss at fixed distance from the outlet and oriented so as to be bisected and symmetrical with respect to the second plane and asymmetrical with respect to the first pane to define a first deflector portion and a second deflector portion different than the first deflector portion, the fluid deflector including:
- a pair of radially extending slots diametrically opposed about the frame boss and bisected by the first plane;
- the first portion of the fluid deflector includes a first peripheral edge having a first arc length extending from one of the pair of diametrically opposed slots to the other, the first peripheral edge being defined by a radius of curvature centered at the sprinkler axis and constant over the first arc length, the first peripheral edge defining a first constant radius over the first arc length;
- the second portion of the fluid deflector includes a second peripheral edge having a second arc length portion extending from one of the pair of diametrically opposed slots, the second peripheral edge having a third arc length portion spaced apart from another with a planar edge extending between the second and third arc length portions, the planar edge being centered about the second plane and parallel to the first plane, the planar edge being located at a distance from the first plane that is less than the first constant radius of curvature of the first peripheral edge.

A window sprinkler system for protection of a window arrangement including a plurality of glass panes extending vertically between an upper window frame and a lower window frame, the plurality of glass panes having a face, the system comprising:
- a firefighting fluid supply pipe;
- and
- a plurality of horizontal window sprinklers coupled to the fluid supply pipe and confronting the glass panes below the upper window frame, each sprinkler including:
- a frame including a body having an inlet, an outlet with an internal passageway extending between the inlet and the outlet along a sprinkler axis;
- and
- a fluid deflector coupled to the frame for distributing firefighting fluid over the face of a glass pane for wetting and cooling the glass pane to address a fire, each of the plurality of sprinklers having a maximum operating pressure of at least 100 psi. independent of window arrangement construction.

A horizontal sidewall window sprinkler comprising:
- a frame including a body having an inlet, an outlet with an internal passageway extending between the inlet and the outlet along a sprinkler axis;
- and
- a fluid deflector located at a fixed distance from the outlet having a face for confronting a window, the fluid deflector consisting of three radially extending slots with each slot having a slot width and a maximum slot length, two of the slots being diametrically opposed about the sprinkler axis and the third slot being centered between the two diametrically opposed slots, the third slot defining a minimum slot width that is greater than any maximum slot length.
