Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 192 words
The combination of an electrical outlet with an extension plate wherein the outlet box has end walls and side walls, and the extension plate is a rigid molded plastic insulator member having a center flange portion sized for telescopic engagement with said outlet box to extend the effective length thereof, said center flange portion being a continuous wall defining an open center area in said plate, and said plate having a continuous peripheral portion for engaging a building surface when said outlet box is positioned in a hole in such surface, and said plate bridges over areas immediately adjacent the entire periphery of said outlet box; and outlet receptacle positioned in said outlet box, said center portion extending into said outlet box to cover and insulate terminal portions on said outlet receptacle from said outlet box; and a strap metal securing strip engaging a side wall of said outlet box and having an elongate section outside the box and protruding longitudinally therebeyond and several positioning fingers extending into and engaging said outlet box wall on the inner surface thereof, and being insulated from any electrical contact means within said center flange portion.
Claim 2
Dependent Claim 192 words
The combination of an electrical outlet with an extension plate wherein the outlet box has end walls and side walls, and the extension plate is a rigid molded plastic insulator member having a center flange portion sized for telescopic engagement with said outlet box to extend the effective length thereof, said center flange portion being a continuous wall defining an open center area in said plate, and said plate having a continuous peripheral portion for engaging a building surface when said outlet box is positioned in a hole in such surface, and said plate bridges over areas immediately adjacent the entire periphery of said outlet box; and outlet receptacle positioned in said outlet box, said center portion extending into said outlet box to cover and insulate terminal portions on said outlet receptacle from said outlet box; and a strap metal securing strip engaging a side wall of said outlet box and having an elongate section outside the box and protruding longitudinally therebeyond and several positioning fingers extending into and engaging said outlet box wall on the inner surface thereof, and being insulated from any electrical contact means within said center flange portion.
Claim 3
Dependent Claim 221 words
The combination of an electrical outlet with an extension plate wherein the outlet box has end walls and side walls, and the extension plate is a rigid molded plastic insulator member having a center flange portion sized for telescopic engagement with said outlet box to extend the effective length thereof, said center flange portion being a continuous wall defining an open center area in said plate, and said plate having a continuous peripheral portion for engaging a building surface when said outlet box is positioned in a hole in such surface, and said plate can bridge over areas immediately adjacent the entire periphery of said outlet box; an outlet receptacle positioned in said outlet box, said center portion extending into said outlet box to cover and insulate terminal portions on said outlet receptacle from said outlet box; and a strap metal securing strip engaging a side wall of said outlet box and having an elongate section outside the box and extending axially beyond the end of the box, said securing strip also having several positioning fingers extending into and engaging said box side wall on the inner surface thereof, said fingers being between said extension plate center section and said box wall, said securing strip being adapted to engage a wall surface spaced axially from the end of said outlet box.
