Abstract
Abstract A safety device is disclosed for use in retaining an electrical plug or the like within an electrical wall outlet socket so as to prevent withdrawal of the plug by a child. The device includes a base portion for securing the device to the electrical outlet and has oppositely directed bifurcated arm portions adapted to engage and retain electrical plugs within the associated electrical outlet sockets to prevent removal of the plugs by a child.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
126 words
A safety device for use in retaining an electrical plug or the like within an electrical outlet socket, said device comprising a unitary member having a base portion adapted to be secured to an electrical outlet, and a pair of bifurcated arm portions extending away from said base portion in opposite directions therefrom, said bifurcated arm portions each having a generally arcuate side profile and defining a pair of spaced arms adapted to extend over and engage the outwardly extending portion of an electrical plug when plugged into the electrical outlet socket to which the device is secured with the cord of the plug extending between said spaced arms, said spaced arms being of sufficient rigidity to prevent unintentional withdrawal of the plug from the socket.
Claim 2
Dependent Claim
126 words
A safety device for use in retaining an electrical plug or the like within an electrical outlet socket, said device comprising a unitary member having a base portion adapted to be secured to an electrical outlet, and a pair of bifurcated arm portions extending away from said base portion in opposite directions therefrom, said bifurcated arm portions each having a generally arcuate side profile and defining a pair of spaced arms adapted to extend over and engage the outwardly extending portion of an electrical plug when plugged into the electrical outlet socket to which the device is secured with the cord of the plug extending between said spaced arms, said spaced arms being of sufficient rigidity to prevent unintentional withdrawal of the plug from the socket.
Claim 3
Dependent Claim
65 words
A safety device as defined in claim 1 wherein said electrical outlet socket includes a pair of outlet sockets and has a threaded opening therebetween, and wherein said base portion of said device is adapted to engage said outlet socket adjacent said threaded opening, said base portion having means associated therewith facilitating attachment of said base to said outlet by means of said threaded opening.
Claim 4
Dependent Claim
13 words
A safety device as defined in claim 1 which is made electrically nonconductive.
Claim 5
Dependent Claim
36 words
A safety device as defined in claim 1 including cord centering means supported by at least one pair of said bifurcated arm portions and adapted to receive an electrical cord therethrough spaced between said bifurcated arms.
Claim 6
Dependent Claim
22 words
A safety device as defined in claim 1 including stabilizing means releasably interconnecting adjacent ends of selected ones of said spaced arms.
Claim 7
Dependent Claim
74 words
A safety device as defined in claim 1 wherein said base portion is generally planar, and wherein said bifurcated arms extend outwardly from the plane of said base portion and define spaced arms having arcuate side profiles such that said arms are concave relative to an associated plug when said device is secured to an electrical outlet with said arms in engagement with a plug the electrical cord of which extends between said arms.
Claim 8
Dependent Claim
59 words
A safety device as defined in claim 6 wherein said bifurcated arms are made so as to prevent removal by a young child of a plug retained by said bifurcated arms, but which can be manipulated by an adult to allow removal of the associated plug without detaching said device from an associated electrical outlet socket when secured thereto.
Claim 9
Dependent Claim
78 words
A safety device as defined in claim 7 wherein said base portion is generally planar and has an opening therethrough facilitating attachment of said device to an electrical wall outlet by a screw, said bifurcated arms defining pairs of substantially parallel spaced arms having arcuate side profile such that concave portions of said pairs of arms engage associated plugs to retain said plugs within associated electrical sockets, said pairs of arms having tabs formed on free ends thereof.
Claim 10
Dependent Claim
184 words
A safety device for use in retaining an electrical plug or the like within an electrical outlet socket, said device comprising a unitary member having a base portion adapted to be secured to an electrical outlet, and a pair of bifurcated arm portions extending away from said base portion in opposite directions therefrom, said bifurcated arm portions each having a generally arcuate side profile and defining a pair of spaced arms adapted to extend over and engage the outwardly extending portion of an electrical plug when plugged into the electrical outlet socket to which the device is secured with the cord of the plug extending between said spaced arms, said bifurcated arms being made so as to prevent removal by a young child of a plug retained by said bifurcated arms, but which can be manipulated by an adult to allow removal of the associated plug without detaching said plug from an associated electrical outlet socket when secured thereto, each of said spaced arms having a skirt wall secured to a lateral edge thereof so as to prevent finger access to an associated plug.
Claim 11
Dependent Claim
184 words
A safety device for use in retaining an electrical plug or the like within an electrical outlet socket, said device comprising a unitary member having a base portion adapted to be secured to an electrical outlet, and a pair of bifurcated arm portions extending away from said base portion in opposite directions therefrom, said bifurcated arm portions each having a generally arcuate side profile and defining a pair of spaced arms adapted to extend over and engage the outwardly extending portion of an electrical plug when plugged into the electrical outlet socket to which the device is secured with the cord of the plug extending between said spaced arms, said bifurcated arms being made so as to prevent removal by a young child of a plug retained by said bifurcated arms, but which can be manipulated by an adult to allow removal of the associated plug without detaching said plug from an associated electrical outlet socket when secured thereto, each of said spaced arms having a skirt wall secured to a lateral edge thereof so as to prevent finger access to an associated plug.
Claim 12
Dependent Claim
39 words
A safety device as defined in claim 9 including a tensioning member separate from but attachable to said bifurcated arm portions so as to prevent movement of said bifurcated arm portions relative to said base portion by a child.
Claim 13
Dependent Claim
60 words
A safety device as defined in claim 10 wherein said tensioning member has a pair of end tabs formed thereon, and wherein each of said bifurcated arm portions includes a slot therein adapted to receive one of said end tabs on said tensioning member so as to releasably retain said tensioning member in assembled relation with said bifurcated arm portions.
