Claims25
A sprinkler assembly comprising:
- a sprinkler head having a base with a passage therethrough, a deflector, a pair of arms extending from said base and supporting said deflector, a heat responsive unit supporting a plug in said passage and being activated by heat to release said plug from said passage, said deflector being fixed to said pair of arms after said heat responsive unit is activated and adapted for deflecting fire suppressant fluid being discharged from said passage;
- and
- a plastic cover, said cover including an end wall, a side wall extending from and around said end wall to form a cavity therebetween, and said cavity receiving said deflector and said arms of said sprinkler head, said side wall including at least one annular rib projecting from said side wall inwardly into said cavity and spaced from said end wall, said end wall, said side wall and said at least one annular rib all being integrally formed from plastic, said deflector captured between said rib and said end wall when said sprinkler head is inserted into said cavity of said cover wherein said rib mounts said cover onto said sprinkler head and retains said cover on said sprinkler head by engagement with said deflector.
A sprinkler assembly comprising:
- a sprinkler head having a base, a deflector, and a pair of arms extending from said base and supporting said deflector;
- and p1 a cover, said cover including an end wall, a side wall extending from and around said end wall to form a cavity therebetween, and said cavity receiving said deflector and said arms of said sprinkler head, said side wall including at least one annular rib projecting from said side wall inwardly into said cavity and spaced from said end wall, said deflector captured between said rib and said end wall when said sprinkler head is inserted into said cavity of said cover wherein said rib mounts said cover onto said sprinkler head and retains said cover on said sprinkler head by engagement with said deflector, wherein said side wall engages said pair of arms of said sprinkler head when said cover is mounted on said sprinkler head.
A sprinkler assembly comprising:
- a sprinkler head having a base, a deflector, and a pair of arms extending from said base and supporting said deflector;
- and
- a cover, said cover including an end wall, a side wall extending from and around said end wall to form a cavity therebetween, and said cavity receiving said deflector and said arms of said sprinkler head, said side wall including at least one annular rib projecting from said side wall inwardly into said cavity and spaced from said end wall, said deflector captured between said rib and said end wall when said sprinkler head is inserted into said cavity of said cover wherein said rib mounts said cover onto said sprinkler head and retains said cover on said sprinkler head by engagement with said deflector, wherein said side wall includes at least one groove formed therein, said groove receiving one of said arms of said sprinkler head.
A sprinkler assembly comprising:
- a sprinkler head having a base, a deflector, and a pair of arms extending from said base and supporting said deflector;
- and
- a cover, said cover including an end wall, a side wall extending from and around said end wall to form a cavity therebetween, and said cavity receiving said deflector and said arms of said sprinkler head, said side wall including at least one annular rib projecting from said side wall inwardly into said cavity and spaced from said end wall, said deflector captured between said rib and said end wall when said sprinkler head is inserted into said cavity of said cover wherein said rib mounts said cover onto said sprinkler head and retains said cover on said sprinkler head by engagement with said deflector, wherein said side wall includes a pair of grooves formed therein, said grooves receiving said arms when said cover is mounted to said sprinkler head.
A sprinkler assembly comprising:
- a sprinkler head having a base, a deflector, a pair of arms extending from said base and supporting said deflector;
- and
- a cover, said cover including an end wall, a side wall extending from and 360 degrees around said end wall to form a cavity therebetween, and said cavity receiving said deflector and said arms of said sprinkler head, said side wall including at least one annular rib projecting from said side wall inwardly into said cavity and spaced from said end wall, said deflector captured between said rib and said end wall when said sprinkler head is inserted into said cavity of said cover wherein said rib mounts said cover onto said sprinkler head and retains said cover on said sprinkler head by engagement with said deflector, wherein said cover includes a projecting tab forming a gripping surface.
A sprinkler assembly comprising:
- a sprinkler head having a base, a deflector, a pair of arms extending from said base and supporting said deflector, a heat responsive unit supporting a plug in said passage and being activated by heat to release said plug from said passage, said deflector being fixed to said pair of arms after said heat responsive unit is activated and adapted for deflecting fire suppressant fluid being discharged from said passage;
- and
- a plastic cover, said cover including an end wall, a side wall extending from and around said end wall to form a cavity therebetween, and said cavity receiving said deflector and said arms of said sprinkler head, said side wall including a snap fit engagement with said deflector when said sprinkler head is inserted into said cavity of said cover wherein said snap fit engagement mounts said cover onto said sprinkler head and retains said cover on said sprinkler head by engagement with said deflector, said end wall and said side wall being integrally formed from plastic.
A sprinkler assembly comprising:
- a sprinkler head having a base, a deflector, and a pair of arms extending from said base and supporting said deflector;
- and
- a cover, said cover including an end wall, a side wall extending from and around said end wall to form a cavity therebetween, and said cavity receiving said deflector and said arms of said sprinkler head, said side wall including a snap fit engagement with said deflector when said sprinkler head is inserted into said cavity of said cover wherein said snap fit engagement mounts said cover onto said sprinkler head and retains said cover on said sprinkler head by engagement with said deflector, wherein said side wall engages said pair of arms of said sprinkler head when said cover is mounted on said sprinkler head.
A sprinkler assembly comprising:
- a sprinkler head having a base, a deflector, and a pair of arms extending from said base and supporting said deflector;
- and
- a cover, said cover including an end wall, a side wall extending from and around said end wall to form a cavity therebetween, and said cavity receiving said deflector and said arms of said sprinkler head, said side wall including a snap fit engagement with said deflector when said sprinkler head is inserted into said cavity of said cover wherein said snap fit engagement mounts said cover onto said sprinkler head and retains said cover on said sprinkler head by engagement with said deflector, wherein said side wall includes at least one groove formed therein, said groove receiving one of said arms of said sprinkler head.
