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. Assembly, installation and maintenance of a molded fixture according to the invention is further improved by the ability to snap-fit together all structural elements of the fixture both internally and externally of the housing.
A combination exit sign and emergency lighting unit comprising a housing capable of supporting the weight of the combination, the housing being formed of a plastic material, at least one emergency lighting unit assembly mountable directly to the housing exteriorly thereof for providing a unit emergency lighting function, and means for removably mounting the assembly to the housing.
A combination exit sign and emergency lighting unit comprising a housing, an emergency lighting unit assembly mountable to said housing exteriorly thereof, the emergency lighting unit assembly comprising means for mounting the assembly to the housing, means mountable to the mounting means for swiveling motion relative thereto, means carried by the swiveling means for providing a track, means mountable for movement on the track and for providing a support, reflective means carried by the support, a lamp carried by the assembly and lens means mountable to the support, the mounting means being formed with an aperture into which at least portions of the means mountable to the mounting means for swiveling motion relative thereto are received, the assembly having a low profile and a range of motion allowing light from the lamp to be directed in a multiplicity of directions.
A combination exit sign and emergency lighting unit having at least one emergency lighting unit assembly mountable to an exit sign portion of the combination, the combination comprising a single housing and wherein the emergency lighting unit assembly is mounted to the housing exteriorly of the housing and means for removably mounting the assembly to the housing.
A combination exit sign and emergency lighting unit having at least one emergency lighting unit assembly mountable to an exit sign portion of the combination, the combination comprising a single housing and wherein the emergency lighting unit assembly is mounted to the housing exteriorly of the housing, means for removably mounting the assembly to the housing and means for supporting the weight of the combination substantially in tension.
A combination exit sign and emergency lighting fixture comprising:
The combination exit sign and emergency lighting fixture of claim 27 wherein the housing comprises means for removably mounting the assembly to the combination, means mountable to the mounting means for swiveling motion relative thereto, means carried by the swiveling means for providing a track, means mountable for movement on the track and for providing a support, reflective means carried by the support, a lamp carried by the support and lens means mountable to the support, the assembly having a range of motion allowing light from the lamp to be directed in a multiplicity of directions.
A combination exit sign and emergency lighting unit having circuitry components comprising at least one battery, interior lamping producing exit sign function, and circuitry elements forming at least one circuit with the at least one battery and the interior lamping, the combination comprising:
A combination exit sign and emergency lighting unit fixture having circuitry components comprising at least one battery, interior lamping producing exit sign function, and circuitry elements forming at least one circuit with the at least one battery and the interior lamping, the combination comprising:
A combination exit sign and emergency lighting unit comprising a housing, the housing having at least one battery, at least one lamp, and associated circuitry mounted interiorly thereof, the housing being capable of supporting the weight of the combination and being formed of a plastic material, means for mounting and supporting the battery, lamp and circuitry within the housing, said mounting and support means being formed of a plastic material, at least one emergency lighting unit assembly mountable to an exit sign portion of the combination, the combination comprising a single housing and wherein the emergency lighting unit assembly is mountable to the housing exteriorly of the housing.
A combination exit sign and emergency lighting unit having at least one emergency lighting unit assembly mountable to an exit sign portion of the combination, the combination having at least one battery, at least one lamp and circuitry associated therewith, means for mounting and supporting the battery and at least major portions of the circuitry, the combination comprising a single housing and wherein the emergency lighting unit assembly is mounted to the housing exteriorly of the housing, the housing and the mounting and supporting means being integrally formed, and means for removably mounting the assembly to the housing.
A combination exit sign and emergency lighting fixture, comprising:
