Abstract
Emergency lighting housing/canopy interfacing structure. The structure employs one or more fasteners which may be positioned into place quickly and simply without the aid of tools in order to retain the housing and canopy securely together. Additional redundance members such as conventional snap-fitting barb members may additionally be employed to assist in installation and for extra safety. The present invention accordingly provides emergency lighting housing/canopy interfaces which allow simple, quick and reliable installation of emergency lighting fixtures, but which add additional structure to support the housing and the considerable load imparted by transformers, batteries and other structure within the housing. A preferred embodiment includes an elongated fastener which may be snapped and rotated into place into mounting posts formed on the canopy. The mounting posts, which protrude into the housing, are thus cammed into place against the housing in order to bias the housing and the canopy securely together.
