Abstract
A concealed sprinkler assembly includes a sprinkler head having a body defining a nozzle, an arm structure extending from the nozzle and a deflector mounted on the arm assembly opposite the nozzle. A mounting or gauge base is secured to the sprinkler head. The base positions the deflector and head with respect to a ceiling. A cover plate is snapped onto the sprinkler head assembly by a pair of metal clips. The clips are fabricated from a material which returns towards an original prebent configuration upon being exposed to a predetermined ambient temperature thereby releasing the cover plate from the assembly.
Claims16
A concealed sprinkler assembly, comprising:
- a sprinkler head assembly including a body defining an orifice an arm extending from said body and a deflector mounted on said arm opposite said orifice;
- a mounting base secured to said sprinkler head body;
- a cover plate;
- and
- clip means on said cover plate for resiliently securing said cover plate to said deflector in a snap-on detent fashion, said clip means releasing said cover plate from said deflector upon exposure to a predetermined ambient temperature, said clip means including a pair of opposed metal clips secured to said cover plate, each of said metal clips including:
- a clip base;
- end tabs integral with said clip base, said end tabs extending upwardly from said clip base;
- and
- an actuator arm resiliently joined to one of said end tabs, said end tabs being configured and dimensioned to capture said deflector with the deflector being positioned between said cover plate and said actuator arms, said actuator arms each moving towards an initial prebent configuration upon exposure to said predetermined ambient temperature.
A concealed sprinkler assembly, comprising:
- a sprinkler head assembly including a body defining an orifice an arm extending from said body and a deflector mounted on said arm opposite said orifice;
- a mounting base secured to said sprinkler head body;
- a cover plate;
- and
- clip means on said cover plate for resiliently securing said cover plate to said deflector in a snap-on detent fashion, said clip means releasing said cover plate from said deflector upon exposure to a predetermined ambient temperature, clip means comprising a pair of individual, opposed metal clips secured to said cover plate, each of said metal clips including:
- a clip base;
- end tabs;
- and
- an actuator arm joined to one of said end tabs, said end tabs being configured and dimensioned to capture said deflector with the deflector being positioned between said cover plate and said actuator arms, and
- wherein said clip base is generally trapezoidal in plan view, said end tabs being joined to the nonparallel sides of said clip base and extending upwardly therefrom.
A cover assembly for a concealed automatic sprinkler assembly, comprising:
- a cover plate;
- and
- clip means on said cover plate for resiliently securing said cover plate to said sprinkler assembly in a snap-on detent fashion and for releasing said cover plate from said sprinkler assembly upon exposure to a predetermined ambient temperature, said clip means including a pair of individual, opposed ternary alloy metal clips secured to said cover plate, said clips returning towards an initial, prebent configuration when the predetermined ambient temperature is reached thereby releasing said cover plate, each of said metal clips including a clip base, end tabs joined to and extending upwardly from said clip base, and a detent tab joined to one of said end tabs, said end tabs being configured and dimensioned to capture at least a portion of said sprinkler assembly with the portion of said sprinkler assembly being positioned between said cover plate and said detent tabs.
A cover assembly for a concealed automatic sprinkler assembly, comprising:
- a cover plate;
- and
- clip means on said cover plate for resiliently securing said cover plate to said sprinkler assembly in a snap-on detent fashion and for releasing said cover plate from said sprinkler assembly upon exposure to a predetermined ambient temperature, said clip means comprising a pair of individual, opposed metal clips secured to said cover plate, each of said metal clips including:
- a clip base;
- end tabs;
- and
- a detent tab joined to one of said end tabs, said end tabs being configured and dimensioned to capture said sprinkler assembly with-the sprinkler assembly being positioned between said cover plate and said detent tabs, and wherein said clip base is generally trapezoidal in plan view, said end tabs being joined to the nonparallel sides of said clip base and extending upwardly therefrom.
