Abstract
Abstract A safety cover for electrical outlets with a dummy plug which is attached by a strap to a plate which is secured between the outlet and a cover plate. The dummy plug is designed with a socket contact surface that pivots one edge of the plug away from the socket when a force direct toward the socket is applied to the opposite edge.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
102 words
A safety device for insertion into the receptacle openings of an electrical outlet having a socket comprising: a plug head having a protective surface, an oppositely facing socket contact surface, a first edge and a second edge located opposite said first edge; pivot means for pivoting said second edge away from a socket in which the device is inserted when a force directed toward the socket is applied to said first edge; a plurality of prongs extending from said socket contact surface, said prongs being positioned on said socket contact surface to be received in the receptacle openings of an electrical outlet.
Claim 2
Dependent Claim
102 words
A safety device for insertion into the receptacle openings of an electrical outlet having a socket comprising: a plug head having a protective surface, an oppositely facing socket contact surface, a first edge and a second edge located opposite said first edge; pivot means for pivoting said second edge away from a socket in which the device is inserted when a force directed toward the socket is applied to said first edge; a plurality of prongs extending from said socket contact surface, said prongs being positioned on said socket contact surface to be received in the receptacle openings of an electrical outlet.
Claim 3
Dependent Claim
33 words
The safety device of claim 1 wherein said socket contact surface is non-planar and has a lowermost point thereon which defines a pivot point and wherein said pivot means includes said pivot point.
Claim 4
Dependent Claim
22 words
The safety device of claim 2 wherein said pivot point is located on said outlet contact surface between said plurality of prongs.
Claim 5
Dependent Claim
29 words
The safety device of claim 1 wherein said socket contact surface is convexly curved defining a curvature to said socket contact surface and said curvature provides said pivot means.
Claim 6
Dependent Claim
28 words
The safety device of claim 4 wherein the curvature has a lowermost point defining a pivot point and said pivot point is located between said plurality of plugs.
Claim 7
Dependent Claim
30 words
The safety device of claim 5 wherein said plurality of prongs extend from said socket contact surface substantially perpendicularly to a line tangent to the lowermost point of said curvature.
Claim 8
Dependent Claim
143 words
A safety device for use with a standard wall electrical outlet that has an outlet plate with a socket aperture and an attachment aperture extending therethrough comprising: an electrically non-conductive plate having a socket opening and an attachment hole extending therethrough, said attachment hole and said socket opening being sized and arranged to correspond with the attachment aperture and socket aperture in the outlet plate; an electrically non-conductive plug having prongs located thereon which are positioned and sized to be received in the receptacle openings of the electrical outlet; and, a flexible strap attached to said electrically non-conductive plate and said electrically non-conductive plug, said strap being of sufficient length and flexibility to allow said plug to be removably inserted into the receptacle openings of the outlet when said electrically non-conductive plate is interposedly secured between the electrical outlet and the outlet plate.
Claim 9
Dependent Claim
143 words
A safety device for use with a standard wall electrical outlet that has an outlet plate with a socket aperture and an attachment aperture extending therethrough comprising: an electrically non-conductive plate having a socket opening and an attachment hole extending therethrough, said attachment hole and said socket opening being sized and arranged to correspond with the attachment aperture and socket aperture in the outlet plate; an electrically non-conductive plug having prongs located thereon which are positioned and sized to be received in the receptacle openings of the electrical outlet; and, a flexible strap attached to said electrically non-conductive plate and said electrically non-conductive plug, said strap being of sufficient length and flexibility to allow said plug to be removably inserted into the receptacle openings of the outlet when said electrically non-conductive plate is interposedly secured between the electrical outlet and the outlet plate.
Claim 10
Dependent Claim
45 words
The safety device of claim 7 wherein said electrically non-conductive plate is interposedly secured between the electrical outlet and the outlet plate and said strap extends from behind said plate a sufficient length to allow said plug to be removably inserted into the receptacle outlets.
Claim 11
Dependent Claim
95 words
The safety device of claim 7 wherein said plug further comprises: a plug head having a protective surface, an oppositely facing socket contact surface, a first edge and a second edge located opposite said first edge; pivot means for pivoting said second edge away from a socket in which the device is inserted when a force directed toward the socket is applied to said first edge; a plurality of prongs extending from said socket contact surface, said prongs being positioned on said socket contact surface to be received in receptacle openings of an electrical outlet.
Claim 12
Dependent Claim
19 words
The safety device of claim 9 wherein said strap is attached to said first edge of said plug head.
