Fire protection sprinkler assembly

A sprinkler assembly comprising:

• a plastic sprinkler frame having a proximal portion, a distal portion, an external surface and an internal surface, the internal surface defining an internal passageway extending from an inlet formed in the proximal portion to an outlet formed in the distal portion to define a longitudinal axis of the sprinkler assembly;
• a support member formed about the distal portion;
• and
• a deflector assembly coupled to the support member, wherein the support member includes a plurality of receiving structures and the deflector assembly includes a plurality of projection members, wherein the support member includes a pair of axially extending stanchions including a first stanchion and a second stanchion, each of the first stanchion and the second stanchion having a proximal portion and a distal portion axially spaced from one another to define an axial length of the stanchion with the proximal portion of the first and second stanchions being formed about the distal portion of the sprinkler frame each stanchion having an internal surface defining an open channel having an axial length extending from the proximal portion to the distal portion of the stanchion, with one of the plurality of the receiving structures being formed and located along the internal surface of the stanchion, and wherein the deflector assembly includes a deflector member having an outer perimeter and a pair of extension members disposed radially from the outer perimeter of the deflector member with each extension member having one of the plurality of projection members, the pair of extension members including a first extension member engaged within the open channel of the first stanchion, the pair of extension members including a second extension member engaged within the open channel of the second stanchion, the plurality of receiving structures being axially located along the channels of the first and second stanchions so that engagement of the plurality of projection members of the extension member with the receiving structures of the stanchions locates the deflector member with respect to the outlet.

A sprinkler assembly comprising:

• a plastic sprinkler frame having a proximal portion, a distal portion, an external surface and an internal surface, the internal surface defining an internal passageway extending from an inlet formed in the proximal portion to an outlet formed in the distal portion to define a longitudinal axis of the sprinkler assembly;
• and
• a support member formed about the distal portion for supporting a deflector assembly, the support member having a pair of projection members;
• the deflector assembly including a deflector member and a receiving structure engaged with the projection members to define a first location of the deflector member relative to the outlet of the sprinkler frame in an unactuated state of the sprinkler assembly and a second location of the deflector member relative to the outlet and distal of the first location in an actuated state of the sprinkler assembly, the deflector assembly including a pair of extension members disposed about the deflector member, each extension member including a plurality of surfaces to define a closed form opening to define the receiving structure including a first surface and a second surface distally spaced from the first surface, each projection member of the support member being spaced from the first surface of the receiving structure to define the first location of the deflector member and each projection member of the support member being disposed within one of the closed formed openings against the first surface of the receiving structure to define the second location of the deflector member.
