  • Patent number: 6883942
    Abstract: A floor lamp that economizes floor space and illuminates and enhances the corner of a room, the functional and ornamental design of which is based on symmetry considerations dictated by the three-dimensional geometry of the corner. The footprint of the lamp base has two sides that form a ninety-degree angle for flush insertion in the corner. A post or other structure attached at its lower end to the base supports a luminaire at its furthest end. The base, post or support structure and luminaire are either symmetric with respect to a vertical plane that bisects the ninety-degree angle of the base, or exhibit balanced asymmetry with respect to the said bisecting plane, as understood by persons skilled in the art. Rectangular lamp bases are excluded by failure either to economize floor space or to meet the above symmetry requirements.

  • Patent number: 6280065
    Abstract: A floor lamp having a base with two sides that intersect in a ninety-degree angle for flush insertion in the corner of a room. A post or other vertical structure is attached to the base with a support device that supports a light fixture above the floor in the open space of the corner. In an alternative embodiment, a post or multiple posts or other support structure is fixed to the base and supports a light fixture flush with the walls of the corner of a room. A room can be illuminated with light diffusely reflected from a ceiling, as well as light radiated directly from the lamp.
