Abstract
Abstract In the attachment of an appliance's electrical supply cord to an ordinary electrical outlet on a wall, it is common to have a plug encasing the cord such that the cord adjacent to the plug will be parallel to the wall when the plug is inserted into the outlet, permitting furniture or other objects in front of the outlet to be set closer to the wall. In this invention, the protrusion of the plug from the outlet is reduced to the width of the electrical cord itself. The invention will be of great value in allowing the cord to lie substantially flat against a wall even at its juncture with the plug and in allowing furniture or other objects to be set approximately a mere width of the cord away from the electrical outlet surface. A pivoting tab whose end can be swung away from the main body of the plug to facilitate grasping for disengaging the plug from the outlet is provided.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
99 words
A device for the attachment of an electrical appliance cord to an electrical outlet comprising a flat one-piece insulating plug of virtually the same thickness as the electrical cord, in which plug are embedded the flat bases of at least two electrical contact prongs, said prongs extending at right angles to said plug, said bases being affixed within the plug to conductor wires within the electrical cord and on which plug there is a pivoting tab whose end can be swung away from the main body of the plug to facilitate grasping for disengaging the plug from the outlet.
Claim 2
Independent Claim
99 words
A device for the attachment of an electrical appliance cord to an electrical outlet comprising a flat one-piece insulating plug of virtually the same thickness as the electrical cord, in which plug are embedded the flat bases of at least two electrical contact prongs, said prongs extending at right angles to said plug, said bases being affixed within the plug to conductor wires within the electrical cord and on which plug there is a pivoting tab whose end can be swung away from the main body of the plug to facilitate grasping for disengaging the plug from the outlet.
Claim 3
Dependent Claim
25 words
The device as claimed in claim 1 above, in which the tab pivots about a geometrical axis that runs through the center of the plug.
Claim 4
Dependent Claim
33 words
The device as claimed in claim 1 above, in which the tab pivots about a geometrical axis that runs through the center of the plug when the plug is disengaged from the outlet.
Claim 5
Dependent Claim
29 words
The device as claimed in claim 1 above, in which the tab forms an outer border of the end of the plug opposite the cord end of the plug.
Claim 6
Dependent Claim
26 words
The device as claimed in claim 1 above, in which the tab is mechanicaly hinged at its point of attachment to the rest of the plug.
Claim 7
Dependent Claim
25 words
The device as claimed n claim 1 above, in which the tab is flexible, allowing it to bend away from the rest of the plug.
Claim 8
Dependent Claim
17 words
The device as claimed in claim 1 above, in which the cord is affixed to the tab.
Claim 9
Dependent Claim
25 words
The device as claimed in claim 1 above, in which there is a strain relief attached to the cord and the plug at their juncture.
Claim 10
Dependent Claim
22 words
The device as claimed in claim 1 above, in which there is fiber reinforcement within the juncture of the cord and plug.
Claim 11
Dependent Claim
37 words
The device as claimed in claim 1 above, in which the prongs and cord are arranged such that the cord runs vertically along a wall upon insertion into a typical electrical outlet having vertical side-by-side contact slots.
Claim 12
Dependent Claim
40 words
The device as claimed in claim 1 above, in which the prongs and cord are arranged such that the cord runs at a non-vertical angle along a wall upon insertion into a typical electrical outlet having vertical side-by-side contact slots.
Claim 13
Dependent Claim
28 words
The device as claimed in claim 1 above, in which the conductor prongs are formed as part of, but bent ninety degrees to, said bases within the plug.
Claim 14
Dependent Claim
15 words
The device as claimed in claim 1 above, in which there are two conductor prongs.
Claim 15
Dependent Claim
27 words
The device as claimed in claim 1 above, in which the prongs are shaped differently from each other in order to fit a typical polarized electrical outlet.
