FIELD OF THE INVENTION
The invention relates generally to an easy to install wall socket plate that obtains power from wall socket terminals, to power at least a third receptacle embedded in the wall socket plate.
BACKGROUND INFORMATION
The invention relates generally to a wall socket plate that can be installed easily to replace existing wall socket plates with at least a third receptacle. The wall socket plate in accordance with the present invention has metal tabs and conductive material on the back of the plate to supply electric current to at least a third receptacle embedded in the plate. More particularly, the metal tabs conduct electric current from socket terminal screws for powering an additional four receptacles in a wall socket plate.
Various wall socket plates with additional features have been devised and constructed to enhance or add to the standard wall socket plate. Examples of enhanced wall socket plates include U.S. Pat. No. 7,318,653 which covers a multiple function wall cover plate with a front cover and a bottom base, prongs to supply electricity from an existing receptacle, a light between the front cover and the back base and a fragrance refill means. The multiple function wall cover plate uses one prong set to plug into an existing wall socket receptacle to power one or more new receptacles on the multiple function wall cover plate and to power the added features of the multiple function wall cover plate. Unlike the present invention, the '653 patent requires the use of existing receptacles to power the multiple function wall cover plate and requires a bulky system to provide new receptacles in order to maintain the original number of receptacles in the wall socket.
