Abstract
Abstract An electrical receptacle cover plate is integrally molded with plug receptacles having prong connector terminals extending rearwardly of a shallow housing portion for plug-in connection, through an opening in panelling or the like used in renovating interior walls, with already-installed electrical receptacles. The plug-in electrical receptacle interconnecting prongs are scored at spaced intervals along their lengths to permit ready adjustment to the length required for inter-receptacle connection, depending upon the distance between the inner wall covered and the outer surface of the new wall. Electrically insulating spacer wafers threaded on the interconnection prong, serve to insulate portions thereof intermediate the existing receptacle and the plug-in receptacle extender.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
124 words
A plug-in electrical receptacle extender comprising, in combination, a flat electrical receptacle cover plate, a comparatively thick body member extending centrally outwardly of one side of said cover plate and integrally formed therewith, a plurality of electrical prong connector terminals secured in said body member and extending perpendicularly outwardly thereof at said one side of said cover plate, end portions of said prong connector terminal extensions being adapted to fit into corresponding prong connector terminal openings in an electrical receptacle to be extended for making electrical connection therewith, and a non-electrically conductive apertured spacer slidingly received over said prongs for electrically insulating said electrical plug terminal extensions between said body member and end portions of said extensions to be fitted into an electrical receptacle.
Claim 2
Dependent Claim
124 words
A plug-in electrical receptacle extender comprising, in combination, a flat electrical receptacle cover plate, a comparatively thick body member extending centrally outwardly of one side of said cover plate and integrally formed therewith, a plurality of electrical prong connector terminals secured in said body member and extending perpendicularly outwardly thereof at said one side of said cover plate, end portions of said prong connector terminal extensions being adapted to fit into corresponding prong connector terminal openings in an electrical receptacle to be extended for making electrical connection therewith, and a non-electrically conductive apertured spacer slidingly received over said prongs for electrically insulating said electrical plug terminal extensions between said body member and end portions of said extensions to be fitted into an electrical receptacle.
Claim 3
Dependent Claim
44 words
A plug-in electrical receptacle extender as defined in claim 1, wherein said prong connector terminal extensions are all scored at spaced intervals along their lengths to provide transverse zones of weakness facilitating breaking off at the selected length for insertion into the electrical receptacle.
Claim 4
Dependent Claim
19 words
A plug-in electrical receptacle extender as defined in claim 1 including a plurality of said non-electrically conductive apertured spacers.
Claim 5
Dependent Claim
43 words
A plug-in electrical extender as defined in claim 3 wherein said prong connector terminal extensions are all scored at spaced intervals along their lengths to provide transverse zones of weakness facilitating breaking off at the selected length for insertion into the electrical receptacle.
