Abstract
A housing frame preferably formable as a single integral unit being capable of use as a primary structural portion of a housing suitable for multiple exit sign configurations, the several exit sign configurations of the invention being either intended for emergency or non-emergency operation and further being intended for use with different light sources and power sources. The frame and associated plates forming the housing of the invention are preferably formed from polymeric material of a thickness less than that of prior 'plastic' housings, the strength and rigidity necessary to proper operation of the housing being provided by a functionally interrelated combination of structural elements which allows a substantial reduction in material used for formation of the housing.
