Residential sidewall fire sprinkler

A residential sidewall sprinkler for mounting to one of two substantially parallel vertical wall surfaces extending between a substantially flat ceiling and a floor to define a coverage area for the sprinkler, the sprinkler comprising:

• a body having an inlet and an outlet defining therebetween a passageway defining a K-factor of about 6 and a longitudinal axis, the body having a proximal end for coupling the sprinkler to a fluid supply line, the body having a distal end opposite the proximal end;
• a deflector assembly having a proximal portion and a distal portion, the deflector assembly being coupled to the distal end of the body such that the proximal end of the deflector is adjacent the distal end of the body, the deflector assembly including:
• a face portion distally spaced from the outlet of the body and substantially orthogonal to a first plane and a second plane intersecting along the longitudinal axis, the face portion including a pair of openings, the deflector assembly further including:
• a first canopy and a second canopy disposed about one of the first and second planes to define a channel therebetween in communication with the opening, at least one of the first and second canopies defining a horizontal component to fluid passing between the canopies such that the deflector assembly provides at least one of a consistent horizontal and vertical fluid distribution pattern for at least one of a substantially constant fluid pressure and substantially constant fluid flow rate provided to the inlet over a range of ceiling-to-canopy distance between the ceiling and one of the first and second canopies, the ceiling-to-canopy distance ranging between four to about twelve inches, each of the first and second canopies bounding a respective one of the pair of openings, and each of the first and second canopies extending proximally and distally of the face portion, the second canopy having a distal end including a plurality of tines including at least one tine defined by a distal edge of the second canopy,
• wherein the face portion includes a pair of parallel lateral portions, each of the lateral portions includes a plurality of undulating portions integral with first and second canopies, the plurality of undulations define a concave radius of curvature relative to the distal portion of the deflector assembly, the plurality of undulations further defining a ratio between the height of the face portion and a length of the first and second canopies of about 1.1.

• wherein the face portion includes a pair of parallel lateral portions, each of the lateral portions includes a plurality of undulating portions integral with first and second canopies, the plurality of undulations define a concave radius of curvature relative to the distal portion of the deflector assembly and a convex curvature relative to the distal end of the deflector assembly, the radius of curvature ranging from about 0.1 inches to about 0.5 inches.

A residential sidewall sprinkler system comprising:

• a fluid supply;
• a coverage area defined by a substantially flat ceiling, a floor and at least one pair of parallel vertical walls between the ceiling and the floor;
• a residential sidewall sprinkler having an actuated and a non-actuated state, the sprinkler including:
• a body having an inlet and an outlet defining therebetween a passageway defining a longitudinal axis and a K-factor of about 6, the body having a proximal end and a distal end opposite the proximal end, the proximal end being coupled to the fluid supply line such that the sprinkler is mounted one of the at least one pair of vertical walls;
• a deflector assembly having a proximal portion and a distal portion, the deflector assembly coupled to the distal end of the body such that the proximal end of the deflector is adjacent the distal end of the body to distribute fluid in the actuated state, the deflector assembly including a face portion spaced from and substantially orthogonal to a first plane and a second plane intersecting along the longitudinal axis, the face portion having a pair of openings, a first plurality of undulating portions and a second plurality of undulating portions disposed about the first plane, each of the first and second plurality of undulating portions defining a concave radius of curvature relative to the distal portion of the deflector assembly, the deflector further including an upper canopy contiguous with the first plurality of undulating portions and a lower canopy axially contiguous with the second plurality of undulating portions, the upper and lower canopies extending about the first plane and relative to the face portion, each of the upper and lower canopies extending proximally and distally of the face portion, and each of the upper and low canopies bounding a respective one of the pair of openings.
