Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
123 words
A charging system adapted for use with a conventional outlet source, said system comprising: (i) a charge current source including a high impedence center tapped transformer, a housing for said transformer, two blades extending from one face of the housing for engagement with the socket outlet source, and fastening means on said face of the housing; and (ii) anchoring means disposed on said outlet and detachable matable with said fastening means, whereby engagement of said fastening means with said anchoring means when the charge current source is plugged into the outlet source provides auxiliary mechanical supporting for the charge current source and any associated modules, said mechanical support occurring simultaneously with the plugging in of the charge current source into the outlet source.
Claim 2
Dependent Claim
123 words
A charging system adapted for use with a conventional outlet source, said system comprising: (i) a charge current source including a high impedence center tapped transformer, a housing for said transformer, two blades extending from one face of the housing for engagement with the socket outlet source, and fastening means on said face of the housing; and (ii) anchoring means disposed on said outlet and detachable matable with said fastening means, whereby engagement of said fastening means with said anchoring means when the charge current source is plugged into the outlet source provides auxiliary mechanical supporting for the charge current source and any associated modules, said mechanical support occurring simultaneously with the plugging in of the charge current source into the outlet source.
Claim 3
Dependent Claim
43 words
The charging system of claim 1 wherein said fastening means on the face of the housing is a female aperture with an inner recessed detent, and the anchoring means on the outlet comprises a pin adapted to enter the aperture and interlock therewith.
Claim 4
Dependent Claim
39 words
The charging system of claim 1, wherein said fastening means on the face of the housing is a first portion of a snap fastener and the anchoring means on the outlet comprises a second portion of a snap fastener.
Claim 5
Dependent Claim
42 words
The charging system of claim 1, wherein said fastening means on the face of the housing is a patch of substantially rigid plastic loops and the anchoring means on the outlet comprises a patch of substantially rigid plastic hooks or vice versa.
Claim 6
Dependent Claim
99 words
A support system for an electrical device including blades adapted to be plugged into the socket of a conventional outlet source, said system comprising: (i) fastening means disposed on the surface of the electrical device adjacent said blades; and (ii) anchoring means disposed on said outlet and detachably matable with said fastening means whereby engagement of said fastening means with said anchoring means when the electrical device is plugged into the outlet source provides auxiliary mechanical support for the electrical device, said mechanical support occurring simultaneously with the plugging in of the charge current source into the outlet source.
Claim 7
Dependent Claim
99 words
A support system for an electrical device including blades adapted to be plugged into the socket of a conventional outlet source, said system comprising: (i) fastening means disposed on the surface of the electrical device adjacent said blades; and (ii) anchoring means disposed on said outlet and detachably matable with said fastening means whereby engagement of said fastening means with said anchoring means when the electrical device is plugged into the outlet source provides auxiliary mechanical support for the electrical device, said mechanical support occurring simultaneously with the plugging in of the charge current source into the outlet source.
Claim 8
Dependent Claim
41 words
The support system of claim 5, wherein said fastening means on the electrical device is a female aperature with an inner recessed detent, and the anchoring means on the outlet comprises a pin adapted to enter the aperture and interlock therewith.
Claim 9
Dependent Claim
37 words
The support system of claim 5, wherein said fastening means on the electrical device is a first portion of a snap fastener, and the anchoring means on the outlet comprises a second portion of a snap fastener.
Claim 10
Dependent Claim
40 words
The support system of claim 5, wherein said fastening means on the electrical device is a patch of substantially rigid plastic loops, and the anchoring means on the outlet comprises a patch of substantially rigid plastic hoods, or vice versa.
Claim 11
Independent Claim
65 words
The system of claims 2 or 6, wherein said outlet includes a conventional cover plate and said anchoring means includes an anchoring pin post having a shank portion extended beyond the face of said cover plate and terminating in an enlarged shoulder portion for engaging the inner recessed detent, and with said shank portion being of sufficient size for maintaining the cover plate in place.
Claim 12
Independent Claim
56 words
The system of claims 3 or 7, wherein said outlet includes a conventional cover plate and said anchoring means includes an anchor screw having a shank which extends beyond the face of the cover plate and terminates in the second portion of a snap fastener, with the shank portion maintaining said cover plate in fixed position.
