Concealed window sprinkler frame arms and body orientation

A sprinkler, comprising:

• a housing;
• a first leg extending from the housing about an axis through the housing, the first leg having a first foot defining a first aperture;
• a second leg extending from the housing about the axis, the second leg having a second foot defining a second aperture;
• a sealing assembly coupled with the housing;
• a first guide pin received in the first aperture, the first guide pin comprising a first head to restrict movement of the first guide pin through the first aperture;
• a second guide pin received in the second aperture, the second guide pin comprising a second head to restrict movement of the second guide pin through the second aperture;
• and a deflector comprising a top surface comprising a front edge, a back wall opposite the front edge extending from the top surface to a straight distal edge at an angle greater than or equal to 90 degrees and less than or equal to 105 degrees, a pair of arms, and a pair of sidewalls, the front edge has a convex curvature around a center of the front edge, the straight distal edge is in a first plane,
• the deflector coupled with the first guide pin and the second guide pin such that an outer edge of the deflector is outward from where the first guide pin and the second guide pin are coupled with the deflector,
• a top edge of each arm of the pair of arms has a straight portion in each of a second plane different than the first plane and a third plane different than the first plane and extends laterally outward from the pair of guide pins and the top surface relative to the axis,
• wherein each arm of the pair of arms forms the gap such that a fourth plane through the gap is between the first corner and the straight distal edge.

A concealed sprinkler, comprising:

• a housing comprising a pair of legs, each leg defining an aperture, each leg extending longitudinally about an axis through the housing;
• a mount extending from the housing in an opposite direction from the pair of legs;
• a sealing assembly coupled with the housing, the sealing assembly to become unsealed responsive to a fire;
• a pair of guide pins, each guide pin of the pair of guide pins received in a respective aperture of a respective foot of each leg of the pair of legs, each guide pin of the pair of guide pins comprising a head sized to not move through the aperture;
• and
• a deflector coupled with the pair of guide pins, the deflector comprising a top surface comprising a front edge, a back wall opposite the front edge extending from the top surface to a straight edge, the straight edge is in a first plane, the back wall angled relative to the top surface at an angle greater than or equal to 90 degrees and less than or equal to 105 degrees, and a pair of arms,
• the front edge has a convex curvature,
• each arm of the pair of arms forms a gap with the top surface, each arm of the pair of arms has a straight portion spaced from the straight edge, each arm of the pair of arms is in each of a second plane and a third plane that are each different from the first plane,
• wherein the second plane and the third plane cross the gap.
