Abstract
Abstract A standing lamp structure in which the base and stem are defined by a unitary acrylic rod which is spiraled to form the base, the center of the spiral leading upwardly to form the stem which terminates in a lamp socket. Running through the rod in bores therein is a pair of parallel wires to conduct current to the socket, the bores having a reflective surface to render the wires effectively imperceptible.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
68 words
A lamp structure comprising a rigid rod of thermoplastic, heat-deformable and light-transmissive material encasing and in contact with spaced-apart electrical conductors extending longitudinally therethrough, each of said electrical conductors having a light-reflective outer surface for reflecting light outwardly therefrom to obscure the presence of said electrical conductors encased within and in contact with said rod, said rod being formable to a desired shape upon the application of heat.
Claim 2
Dependent Claim
68 words
A lamp structure comprising a rigid rod of thermoplastic, heat-deformable and light-transmissive material encasing and in contact with spaced-apart electrical conductors extending longitudinally therethrough, each of said electrical conductors having a light-reflective outer surface for reflecting light outwardly therefrom to obscure the presence of said electrical conductors encased within and in contact with said rod, said rod being formable to a desired shape upon the application of heat.
Claim 3
Dependent Claim
15 words
A lamp structure according to claim 1, wherein said electrical conductors are coated with silver.
Claim 4
Dependent Claim
15 words
A lamp structure according to claim 2, wherein said rod is fabricated of acrylic material.
Claim 5
Dependent Claim
71 words
A lamp structure comprising a rigid rod of thermoplastic, heat-deformable and light-transmissive material encasing and in contact with electrical conductors longitudinally therethrough within bores in said rod, the internal surface of each of said bores being abraded to reflect light outwardly therefrom to obscure the presence of said electrical conductors encased within and in contact with said rod, said rod being formable to a desired shape upon the application of heat.
Claim 6
Dependent Claim
71 words
A lamp structure comprising a rigid rod of thermoplastic, heat-deformable and light-transmissive material encasing and in contact with electrical conductors longitudinally therethrough within bores in said rod, the internal surface of each of said bores being abraded to reflect light outwardly therefrom to obscure the presence of said electrical conductors encased within and in contact with said rod, said rod being formable to a desired shape upon the application of heat.
Claim 7
Dependent Claim
15 words
A laMp structure according to claim 4, wherein said rod is fabricated of acrylic material.
