ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to cover assemblies for floor mounted electrical receptacles.
A floor mounted electrical receptacle is typically contained in a structure known as a floor box. Electrical power lines are routed upward to the receptacle through an open lower end of the floor box. A cover assembly at the floor surface conceals the floor box from view. The cover assembly has an access door that can be opened to provide access to the receptacle in the floor box.
SUMMARY OF THE INVENTION
The present invention is an apparatus for use with an electrical receptacle and a floor box. In accordance with a principal feature of the invention, the apparatus comprises a ring, a cover, and a gasket. The ring is configured to support the receptacle within an open upper end portion of the floor box. The cover has an access opening for providing access to the receptacle, and has an access door for closing the access opening. The ring, the cover and the gasket are configured for interconnection in installed positions in which a portion of the gasket is deflected into an annular configuration interposed radially between the ring and the cover. When the gasket is thus installed between the ring and the cover, the annular portion of the gasket establishes a seal that surrounds the access opening in the cover.
In accordance with another principal feature of the invention, the cover is circular and has a peripheral edge portion that projects radially outward from the floor box fully around the circumference of the floor box. The cover further has apertures for receiving fasteners that fasten the cover in its installed position. The door is configured to overlie all of those apertures, and thereby to conceal all of the corresponding fasteners from view, when the door is in a closed position.
