Appl. No.:

09/703322

Inventors:

Mark Campbell Logan - Doraville GA
Andrew Edward Masters - Berlin MD
Edwin Lewis Hull - Conyers GA

Assignee:

Acuity Brands, Inc. - Atlanta GA

International Classification:

B60Q 304

US Classification:

362362, 362234, 362249, 362370, 362812, 40570

Abstract:

An emergency lighting fixture combining the functions of an illuminated sign such as an exit sign and an emergency lighting unit integrated into one housing onto which one or more emergency lights can be mounted at predetermined locations of the housing, the combined emergency lighting structure providing both exit location information and ambient emergency lighting in a single cooperatively operating device. The present device replaces bulky prior combinations of discrete exit signs and emergency lighting units which have been assembled together essentially as individual devices without integration into a single housing or without substantial integration of operational features, the housing of the present device being only slightly larger than standard exit signage. The present fixture is preferably formed from light weight materials such as polycarbonate/ABS or sheet metal configured to mount in tension internal weight such as weight due to enlarged battery mass and the like as well as externally mounted emergency lights. Manufacture of the present fixture is improved by the ability to mold major portions of the fixture from suitable polymeric materials, thereby allowing formation of substantial portions of the fixture located internally of the housing integrally with the housing to substantially reduce the number of parts necessary to be assembled together in an assembly situation.

International Classification:

G09F 13/04

US Classification:

40570, 439537

Abstract:

Canopy mounting devices that cover junction boxes of various configurations and provide a pleasing, finished appearance to a resulting installation are disclosed. Certain embodiments of a canopy mounting device include a universal mounting plate integrally formed with a connector of the mounting device such that direct mounting to junction boxes of different configurations is possible. The mounting devices accommodate not only appropriate mountings of junction boxes within ceilings or walls but also inappropriate mountings, such as when junction boxes are recessed too deeply within a ceiling or wall or mounted with junction box edges extending outwardly from the ceiling or wall.
