CROSS REFERENCE TO RELATED APPLICATIONS
This application is related to and claims priority from Provisional Patent Application Ser. No. 60/885,244 filed Jan. 17, 2007, Provisional Patent Application Ser. No. 60/885,245 filed Jan. 17, 2007 and Provisional Patent Application Ser. No. 60/871,163 filed Dec. 21, 2006.


FIELD OF THE INVENTION
The present invention relates, in general, to electrical wall outlets and electrical cords having at least one plug connection for plugging an electrically operated device into and, more particularly, this invention relates to an expandable electrical plug connector for plugging a plurality of such electrically operated devices therein.
BACKGROUND OF THE INVENTION
Prior to the conception and development of the present invention, as is generally well known in the art, electrical wall plugs and extension cords have been in widespread use to provide power to electrical devices.
As is equally well recognized, these electrical wall plugs and extension cords have outlets which are oftentimes spaced relatively close together. Such closely spaced outlets can make it quite difficult at times to plug in more than one device at a time in some wall outlets and/or extension cords because the outlets are normally spaced relatively close together. This is particularly the case with certain types of plugs attached to the device. These plugs come in a large variety of sizes and shapes. Examples of these devices at least include, but are not limited to, kitchen appliances, lamps, audio equipment, television, radio, alarm clocks, electric razors, hair dryers, etc.
Even if one is able to plug more than one plug into an electrical outlet it may be quite difficult to remove the plug due to their close proximity to one another. Although in building a new structure such as a home or commercial building it is possible to provide sufficient outlets to alleviate the above identified problem it is not likely that a building will be rewired just for this problem alone.
SUMMARY OF THE INVENTION
The present invention provides an electrical outlet apparatus equipped to receive power from an electrical receptacle of a wall outlet power source. The electrical outlet apparatus includes a predetermined plurality of outlets capable of extending a predetermined distance apart for distributing a power input from such wall outlet power source to at least one pre-selected object electrically connected to one of such predetermined plurality of outlets. The electrical outlet apparatus includes a first means engageable in and electrically connected to such wall outlet power source for supplying power to such apparatus. A predetermined number of electrical plug receptacles are arranged in a predetermined pattern and are electrically connected to receive electrical power from such first electrical plug receptacle engaged in such wall outlet power source. There is a second means engageable at a predetermined location with each of such predetermined number of electrical plug receptacles for spacing them a predetermined distance apart to facilitate insertion and removal of plugs attached to such pre-selected objects. Such second means is capable of expanding and retracting the predetermined number of such electrical plug receptacles.
