Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 126 words
An electrical outlet accessory for restricting removal of electrical plugs from electrical receptacles comprising a securing post adapted for securement to a duplex receptacle, and a cover releasably securable to said securing post, said cover including access means therein to allow selective placement of up to two electrical plugs essentially within said cover with the associated electrical cord thereof passing through electrical cord ports in the cover, said cover being selectively engageable with said post at various positions to accomodate electrical plugs of different configuration and selectively disengageable from said post to allow plug removal from an insertion into such receptacle and wherein said securing post includes a projection to the rear face thereof for insertion in one of the ground connectors of such duplex receptacle.
Claim 2
Dependent Claim 126 words
An electrical outlet accessory for restricting removal of electrical plugs from electrical receptacles comprising a securing post adapted for securement to a duplex receptacle, and a cover releasably securable to said securing post, said cover including access means therein to allow selective placement of up to two electrical plugs essentially within said cover with the associated electrical cord thereof passing through electrical cord ports in the cover, said cover being selectively engageable with said post at various positions to accomodate electrical plugs of different configuration and selectively disengageable from said post to allow plug removal from an insertion into such receptacle and wherein said securing post includes a projection to the rear face thereof for insertion in one of the ground connectors of such duplex receptacle.
Claim 3
Dependent Claim 30 words
An electrical outlet accessory as claimed in claim 1, wherein said cover includes a slot extending inwardly from an edge of said cover and connected to apertures in said cover.
Claim 4
Dependent Claim 57 words
An electrical outlet accessory as claimed in claim 1, wherein said securing post has an exterior surface of a shape defining a ratchet-type relationship with opposed arms of said cover biased to lock with the surface of said post and disengageable therefrom by forcing said arms apart to allow removal of said cover from said securing post.
Claim 5
Dependent Claim 40 words
An electrical outlet accessory as claimed in claim 3, wherein said securing post and said cover are made of an injection moldable plastic and said post is securable to the central threaded aperture normally used to secure a cover plate.
Claim 6
Dependent Claim 23 words
An electrical outlet accessory as claimed in claim 2, wherein said cover opposite said slot includes a reinforcing rib interior to said cover.
Claim 7
Dependent Claim 48 words
An electrical outlet accessory as claimed in claim 2, wherein said securing post to either side thereof includes cover engaging flange means which cooperates with stepped regions on either side of said cover to generally fix the cover in a non-pivotal relationship with said post when inserted thereon.
Claim 8
Dependent Claim 31 words
An electrical outlet accessory as claimed in claim 1, wherein said securing post is adapted for securement with the central aperture of a duplex receptacle used to secure a cover plate.
Claim 9
Dependent Claim 144 words
In combination, an electrical outlet accessory and a duplex electrical receptacle, said electrical outlet accessory restricting removal of electrical plugs from said electrical receptacle, said accessory comprising a securing post releasably secured to said duplex receptacle, and a cover having a central aperture therein for receiving said securing post, said cover including access means therein for allowing placement of up to two electrical plugs essentially within said cover one on either side of said central aperture with the associated electrical cord of each plug extending beyond the cover through apertures, said cover being selectively engageable with said post at various positions to accomodate electrical plugs of different configuration and selectively disengageable from said post without tools to allow removal or insertion of a plug from said receptacle and wherein said securing post includes a projection received in a ground connector of said duplex receptacle.
Claim 10
Dependent Claim 144 words
In combination, an electrical outlet accessory and a duplex electrical receptacle, said electrical outlet accessory restricting removal of electrical plugs from said electrical receptacle, said accessory comprising a securing post releasably secured to said duplex receptacle, and a cover having a central aperture therein for receiving said securing post, said cover including access means therein for allowing placement of up to two electrical plugs essentially within said cover one on either side of said central aperture with the associated electrical cord of each plug extending beyond the cover through apertures, said cover being selectively engageable with said post at various positions to accomodate electrical plugs of different configuration and selectively disengageable from said post without tools to allow removal or insertion of a plug from said receptacle and wherein said securing post includes a projection received in a ground connector of said duplex receptacle.
Claim 11
Dependent Claim 30 words
The combination as claimed in claim 8, wherein said cover includes a single slot extending inwardly from an edge of said cover and connected to said apertures in said cover.
Claim 12
Dependent Claim 166 words
An electrical outlet accessory for restricting removal of electrical plugs from electrical receptacles comprising a securing post adapted for securement to a duplex receptacle and a cover releasably securable to said securing post, said cover having a central aperture therein for receiving said securing post and allowing a portion of said securing post to pass therethrough, said cover including opposed arms on either side of said central aperture biased to engage with the surface of said post when said post is received in said central aperture, said arms including projections for cooperating with the surface of said post to lock said cover to said post when said post is engaged by said projections and movable to a disengaged position for removing said cover from said post without requiring tools, said cover being sized to receive therewithin an electrical plug on either side of said central aperture and including access means associated with said central aperture for allowing electrical cords of such electrical plugs to pass therethrough.
Claim 13
Dependent Claim 166 words
An electrical outlet accessory for restricting removal of electrical plugs from electrical receptacles comprising a securing post adapted for securement to a duplex receptacle and a cover releasably securable to said securing post, said cover having a central aperture therein for receiving said securing post and allowing a portion of said securing post to pass therethrough, said cover including opposed arms on either side of said central aperture biased to engage with the surface of said post when said post is received in said central aperture, said arms including projections for cooperating with the surface of said post to lock said cover to said post when said post is engaged by said projections and movable to a disengaged position for removing said cover from said post without requiring tools, said cover being sized to receive therewithin an electrical plug on either side of said central aperture and including access means associated with said central aperture for allowing electrical cords of such electrical plugs to pass therethrough.
Claim 14
Dependent Claim 17 words
An accessory as claimed in claim 10, wherein said access means and said central aperture are interconnected.
