Wall-mounted electrical power supply

Claim 2

An electrical supply device, comprising: a housing, a reel rotatably supported in said housing, an extension cord wound on said reel, electrical socket means on one end of said extension cord, whereby the cord may be pulled from the housing to dispose the socket means at selected locations, an electrical receptacle mounted in said housing and having externally accessible socket openings therein, electrical prongs extending from the housing for mounting the housing on a wall outlet, and means for electrically connecting the prong means to said extension cord and to said electrical receptacle so that the extension cord and receptacle are electrically parallel.

Claim 3

An electrical supply device according to claim 1, wherein said electrical connecting means comprises: annular track means carried by the reel, and resilient electrical contact means carried by the housing for slidable engagement with said track means, whereby electrical power is delivered to said track means in any rotational position of the reel.

Claim 4

An electrical supply device according to claim 1, wherein said electrical prong means comprise two sets of prongs insertable into a double wall outlet.

Claim 5

An electrical supply device according to claim 3, wherein: each set of prongs comprises three prongs, said electrical connecting means comprises three separate connector strips extending along an inner surface of said housing so that each connector strip electrically engages one prong of each set of prongs.

Claim 6

An electrical supply device according to claim 4, wherein said electrical connecting means comprises: three concentric annular tracks carried by the reel, and three resilient electrical contacts extending from respective ones of said connector strips for slidable engagement with respective ones of the annular tracks, whereby electrical power is delivered to the tracks in any rotational position of the reel.

Claim 7

An electrical supply device according to claim 5, and further comprising: a cylindrical shaft mounted within said housing and coaxial with the concentric annular tracks, said reel having two side walls defining aligned circular holes fitting about said shaft, whereby the reel is rotatably supported within the housing.

Claim 8

An electrical supply device according to claim 6, and further comprising: a spiral leaf spring within said reel for biasing the reel toward a position wherein the extension cord is fully wound on the reel, said spiral leaf spring having one end thereof connected to the shaft and the other end thereof connected to the reel.

Claim 9

An electrical supply device comprising: a housing having a front wall, a rear wall, and a peripheral wall joining said front and rear walls, electrical prong means extending from said housing rear wall for insertion into electrical sockets in a wall outlet, whereby the housing can be detachably mounted on a building wall, a reel rotatably mounted within said housing for rotation about a central axis parallel to said electrical prong means, an electrical extension cord wound on said reel, said extension cord having electrical socket means located externally of the housing, whereby said cord may be drawn out of the housing to relocate the socket means at locations at selected distances from said housing, an electrical receptacle mounted within said housing adjacent the reel so that socket openings in the receptacle are externally accessible for supplying current to electrical appliances, electrical connector means extending between said electrical prong means and said receptacle to deliver electrical power to the receptacle socket openings, electrical contact means extending from said prong means within said housing, and annular electrical track means carried by said reel for slidable engagement with said contact means, whereby electrical power is delivered to said electrical track means in any position of rotation of the reel, said extension cord having therein electrical connections to said electrical track means for supplying current to electrical appliances plugged into said socket means.

Claim 10

An electrical supply device comprising: a housing having a front wall, a rear wall, and a peripheral wall joining said front and rear walls, electrical prong means extending from said housing rear wall for insertion into electrical sockets in a wall outlet, whereby the housing can be detachably mounted on a building wall, a reel rotatably mounted within said housing for rotation about a central axis parallel to said electrical prong means, an electrical extension cord wound on said reel, said extension cord having electrical socket means located externally of the housing, whereby said cord may be drawn out of the housing to relocate the socket means at locations at selected distances from said housing, an electrical receptacle mounted within said housing adjacent the reel so that socket openings in the receptacle are externally accessible for supplying current to electrical appliances, electrical connector means extending between said electrical prong means and said receptacle to deliver electrical power to the receptacle socket openings, electrical contact means extending from said prong means within said housing, and annular electrical track means carried by said reel for slidable engagement with said contact means, whereby electrical power is delivered to said electrical track means in any position of rotation of the reel, said extension cord having therein electrical connections to said electrical track means for supplying current to electrical appliances plugged into said socket means.
