Abstract

Abstract A lamp having a plurality of tubes connected at joints which permit full rotation adjustment while maintaining electrical continuity from a plug source at one end to a light bulb at the opposite end. Each joint has two cylinders rotatably coaxially joined by a rivet with a conducting sleeve. Each tube has a central contact which is spring-urged against the sleeve to provide a part of the circuit. The tubes and cylinders provide the remainder of the circuit and are insulated from the contacts and sleeves.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 212 words
An adjustable lamp, comprising: a. a plurality of hollow electrically conductive tubes; b. spring-urged contacts within said tubes, said spring-urged contacts being electrically insulated from said tubes; c. at least one adjustable joint, each said adjustable joint including independent inner and outer electrical paths, said tubes being secured to said joints such that said tubes are in electrical communication with each other through said outer electrical paths and such that said spring-urged contacts are in electrical communication with each other through said inner electrical paths, each said adjustable joint comprising: i. a plurality of electrically conductive cylinders, said cylinders being joined rotatably and coaxially by a rivet; ii. each said cylinder having formed therein an opening to receive one of said tubes in electrical communication therewith; iii. a conducting sleeve on said rivet, said conducting sleeve extending between said cylinders and electrically insulated therefrom, said spring-urged contacts of said tubes being in electrical communication with said sleeve; iv. said cylinders being in mutual electrical communication; d. a light bulb, said light bulb being in electrical communication with one of said tubes and one of said springurged contacts; and e. a source of electrical power, said source being connected to one of said tubes and one of said contacts to energize said bulb.
Claim 2
Dependent Claim 212 words
An adjustable lamp, comprising: a. a plurality of hollow electrically conductive tubes; b. spring-urged contacts within said tubes, said spring-urged contacts being electrically insulated from said tubes; c. at least one adjustable joint, each said adjustable joint including independent inner and outer electrical paths, said tubes being secured to said joints such that said tubes are in electrical communication with each other through said outer electrical paths and such that said spring-urged contacts are in electrical communication with each other through said inner electrical paths, each said adjustable joint comprising: i. a plurality of electrically conductive cylinders, said cylinders being joined rotatably and coaxially by a rivet; ii. each said cylinder having formed therein an opening to receive one of said tubes in electrical communication therewith; iii. a conducting sleeve on said rivet, said conducting sleeve extending between said cylinders and electrically insulated therefrom, said spring-urged contacts of said tubes being in electrical communication with said sleeve; iv. said cylinders being in mutual electrical communication; d. a light bulb, said light bulb being in electrical communication with one of said tubes and one of said springurged contacts; and e. a source of electrical power, said source being connected to one of said tubes and one of said contacts to energize said bulb.
Claim 3
Dependent Claim 21 words
An adjustable lamp in accordance with claim 1, wherein: at least one said tube is rotatably secured to said adjustable joint.
Claim 4
Dependent Claim 33 words
An adjustable lamp in accordance with claim 2, wherein: said rotatably secured tube is provided with an annular groove at its secured end for rotatable engagement with pins secured to said adjustable joint.
