Abstract
Abstract A decoupler and method for decoupling a plug of a power cord from the electrical outlet. The device comprises at least one flanged means which is adaptable to be grasped by a user's fingers to exert a pulling force at a distance from the plug to decouple the plug from the outlet and means for retaining the decoupler to the power cord. The method comprises the steps of selectively positioning a flanged means on the wire of a power cord at a distance from the plug of the cord; fixing the flanged means to the power cord, grasping the flanged means with a user's fingers; and applying a pulling force to the flanged means with the user's fingers to decouple the plug from an electrical outlet.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
99 words
In combination with an electrical power cord having a plug operatively connected to one end of a wire for operatively connecting said wire to an electrical outlet, a decoupler for decoupling said plug from said outlet comprising at least one collar which is detached from said plug and fixed in embracing relationship to the wire at a distance from said plug, said collar being adapted to be grasped by a user's fingers to exert a pulling force at a distance from said plug; and a means for affixing said decoupler to the wire at a distance from said plug.
Claim 2
Dependent Claim
99 words
In combination with an electrical power cord having a plug operatively connected to one end of a wire for operatively connecting said wire to an electrical outlet, a decoupler for decoupling said plug from said outlet comprising at least one collar which is detached from said plug and fixed in embracing relationship to the wire at a distance from said plug, said collar being adapted to be grasped by a user's fingers to exert a pulling force at a distance from said plug; and a means for affixing said decoupler to the wire at a distance from said plug.
Claim 3
Dependent Claim
15 words
The combination recited in claim 1 wherein said collar is formed integral with said wire.
Claim 4
Dependent Claim
13 words
The combination recited in claim 1 wherein said collar is a circular collar.
Claim 5
Dependent Claim
56 words
The combination recited in claim 1 further comprising a plurality of unconnected collars detached from said plug and located at varying distances from said plug, each collar being in embracing relationship to said wire and adapted to be grasped by the fingers of a user to exert a pulling force at a distance from said plug.
Claim 6
Dependent Claim
92 words
The combination recited in claim 1 wherein said collar comprises: aligned half portions of a split collar and a thin narrow folded strap interconnecting said half collar portions and having apertures in the center portion thereof for receiving the terminals of a plug and said half collar portions being adapted to be grasped with a user's fingers to exert a pulling force at a distance from said plug; and a circular spring clip tightly embracing said folded strap for retaining the folded strap and adjoining half collar portions to a power cord.
Claim 7
Dependent Claim
83 words
The combination recited in claim 1 wherein said decoupler is selectively positionable on said wire to vary the distance of said decoupler from said plug, said decoupler comprising a tubular portion for slideably engaging the wire of a power cord and adjoining resilient jaw collar portions embracing said wire for tightly gripping said wire when a force is applied with said user's fingers to deflect said collars inwardly to exert a pulling force with the user's fingers at a distance from said plug.
Claim 8
Dependent Claim
19 words
The device recited in claim 1 wherein said means for affixing said decoupler to said wire is an adhesive.
Claim 9
Dependent Claim
20 words
The device recited in claim 1 wherein said means for affixing said decoupler to said wire is a friction means.
Claim 10
Dependent Claim
20 words
The device recited in claim 1 wherein said means for affixing said decoupler to said wire is a gripping means.
Claim 11
Dependent Claim
112 words
In combination with an electrical power cord having a plug operatively connected to one end of a wire for operatively connecting said wire to an electrical outlet, a decoupler for decoupling said plug from said outlet comprising: a resilient body, said body having a tapered portion, an adjoining end shoulder portion, an aperture extending axially through the body, and an inward pointed projection extending circumferentially around said aperture; and a cylindrical collar having a tapered aperture for enaging the conical half portions of the body, to retain said body to said wire and adapted to be grasped by a user's fingers to exert a pulling force at a distance from said plug.
Claim 12
Dependent Claim
112 words
In combination with an electrical power cord having a plug operatively connected to one end of a wire for operatively connecting said wire to an electrical outlet, a decoupler for decoupling said plug from said outlet comprising: a resilient body, said body having a tapered portion, an adjoining end shoulder portion, an aperture extending axially through the body, and an inward pointed projection extending circumferentially around said aperture; and a cylindrical collar having a tapered aperture for enaging the conical half portions of the body, to retain said body to said wire and adapted to be grasped by a user's fingers to exert a pulling force at a distance from said plug.
Claim 13
Independent Claim
74 words
A method for decoupling an electrical plug operatively connected to a wire of a power cord for an outlet comprising the steps of: grasping a collar on said wire which is detached from said plug and fixed in embracing relationship to the wire at a distance from said plug with the fingers of a user; and applying a pulling force to said collar with the user's fingers to decouple the plug from the outlet.
Claim 14
Independent Claim
74 words
A method for decoupling an electrical plug operatively connected to a wire of a power cord for an outlet comprising the steps of: grasping a collar on said wire which is detached from said plug and fixed in embracing relationship to the wire at a distance from said plug with the fingers of a user; and applying a pulling force to said collar with the user's fingers to decouple the plug from the outlet.
Claim 15
Dependent Claim
46 words
The method for decoupling an electrical plug operatively connected to a wire of a power cord from an outlet recited in claim 11 further comprising the initial step of selectively positioning said collar on the wire of the power cord at a distance from the plug.
