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.
Structure d'interface boîtier/monture pour éclairage de sécurité. La structure emploie une ou plusieurs fixations qui se mettent en place rapidement et simplement sans recours à des outils pour assujettir fermement le boîtier et la monture l'un à l'autre. On peut aussi employer des éléments additionnels redondants, tels que des éléments cannelés classiques à encliquetage, pour faciliter l'installation et accroître la fiabilité. La présente invention fournit donc des interfaces boîtier/monture pour éclairage de sécurité qui permettent une installation simple, rapide et fiable d'appareils d'éclairage de sécurité, mais qui ajoutent une structure additionnelle pour supporter le boîtier et la charge considérable qu'imposent les transformateurs, les batteries et autre structure à l'intérieur du boîtier. Une application préférée comprend une fixation allongée qui peut être encliquetée et tournée en place dans des tiges de montage formées sur la monture. Les tiges de montage, qui font saillie dans le boîtier, sont ainsi poussées en place contre le boîtier de manière à rattacher solidement le boîtier et la monture l'un à l'autre.
