ABSTRACT:
A decorative cover for smoke detectors and like devices mounted on a wall or ceiling provides a cover member of a generally opaque material approximately the shape of the device it is covering and somewhat larger than the device to be covered. The cover is provided with a plurality of connector resilient legs fixed to the inside of the cover and extending towards the device to be covered in the pattern to engage selected distributed points of engagement. Cam surfaces on the ends of the resilient legs are position to laterally deflect the respective legs when they contact the distributed points of engagement. Forces imposed by the resilience of the legs while deflected are directed in opposition to one another to maintain frictional engagement at respective points of engagement. But rather than relying strictly on friction, a shoulder beyond the cam surface toward the cover is positioned to move behind structure so that the shoulder will effectively latch to the structure with the resilience of opposed legs holdings the legs in latched position. However, the resilient forces may be easily overcome by manual force in removing the cover. The outer surface of the cover may be provided selectively with color, patterned, or decorated surfaces, including advertisements or pictural scenes.
