Protection of an electric sign such as an emergency exit sign installed in a public place, uses durable base and diffuser, fixed by secure screws and with internal screen to hide fixing to wall

摘要

The electric sign has a base (12) in a durable material, forming an open frame that accepts standard components (14) for emergency signs. The frame has inner flanges (24,28) to allow fixing (60) to walls and outer flanges (40,44) that support the diffuser (50), which is fixed to the frame with secure screws (52). An internal screen (62) hides from view components fixing the sign to the wall.
