Abstract
Abstract A lamp comprised of modular elements for selected assembly to provide a multiplicity of lamp forms. Said elements comprehend a cylindric element with planar parallel ends, a toroid sector element, and a bulb-carrying element or hood; there being means integral with said elements for stable interfitting relationship but which permit of ease of disengagement.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
174 words
A modular lamp comprised of a plurality of discrete components for assemblage into end to end relationship, each component having an upper end and a lower end and being generally circular in cross-section at such upper and lower ends, each component having a sidewall and a downwardly opening recess at its lower end, all but one remaining of said components having a projection at its upper end of reduced cross-section relative to such component end for reception within the recess at the lower end of the immediately superimposed component, the relative dimensions of the cooperating recess and projection being such as to permit rotation of one component about its axis independently of any other component for selected positioning of one component relative to the other, said remaining one of said components having a recess at its lower end, means defining a hood on the upper end of said remaining one component said hood having a translucent element, and illuminating means provided in said remaining one component and positioned to project light through said element.
Claim 2
Dependent Claim
174 words
A modular lamp comprised of a plurality of discrete components for assemblage into end to end relationship, each component having an upper end and a lower end and being generally circular in cross-section at such upper and lower ends, each component having a sidewall and a downwardly opening recess at its lower end, all but one remaining of said components having a projection at its upper end of reduced cross-section relative to such component end for reception within the recess at the lower end of the immediately superimposed component, the relative dimensions of the cooperating recess and projection being such as to permit rotation of one component about its axis independently of any other component for selected positioning of one component relative to the other, said remaining one of said components having a recess at its lower end, means defining a hood on the upper end of said remaining one component said hood having a translucent element, and illuminating means provided in said remaining one component and positioned to project light through said element.
Claim 3
Dependent Claim
41 words
A modular lamp as defined in claim 1 and further characterized bY each component being of tubular character, said components being of like diameter at their lower ends, and of like diameter at their upper ends adjacent to the respective projections.
Claim 4
Dependent Claim
46 words
A modular lamp as defined in claim 1 and further characterized by means provided internally of the lower end of each component for abutting the end margin of the projection of the adjacent component for limiting the relative reception of the same within the related recess.
Claim 5
Dependent Claim
65 words
A modular lamp as defined in claim 3 and further characterized by each of said projections being disposed radially inwardly of the side wall of the associated component, an endwise directed shoulder extending between each projection and the related side wall, the end margin of the lower end portion of the adjacent component being presented radially outwardly of the received projection and abutting said shoulder.
Claim 6
Dependent Claim
48 words
A modular lamp as defined in claim 3 and further characterized by said abutting means comprising ridges presented internally of, and spacedly from, the lower end portion of each component for extension radially inwardly from the side wall thereof for abutting the end margin of the received projection.
Claim 7
Dependent Claim
31 words
A modular lamp as defined in claim 1 and further characterized by the component immediately adjacent said one remaining component having a curvilinear axis defining an angle of less than 180*.
Claim 8
Dependent Claim
31 words
A modular lamp as defined in claim 1 and further characterized by the component immediately adjacent said one remaining component having its longitudinal axis turned through an angle of approximately 45*.
Claim 9
Dependent Claim
32 words
A modular lamp as defined in claim 1 and further characterized by the two components adjacent said one remaining component each having their longitudinal axes turned through an angle of approximately 45*.
