ABSTRACT:
A collapsible lamp shade which can be assembled quickly and easily in any desired one of a variety of interchangeable external configurations comprising an interchangeable shade member formed of one of various flexible fabric materials having upper and lower continuous collar portions, upper and lower interchangeable hoop members, each including an outer circumferentially extending sidewall around which one of the shade member collar portions is located, and a substantially horizontal shelf portion which maintains the location of each collar portion. A plurality of support rods extend between the opposed hoop members to stretch the shade member, while, conversely, the stretched shade member maintains the support rods in a fixed position within the hoop members. One of various contour ring members may be located over a sidewall of and against a shelf portion of one or both hoop members to give a desired interchangeable outer configuration to the shade member and an interchangeable inner liner may be provided.
Additionally, a separate spider assembly for supporting the lamp shade may be provided which is itself collapsible, and includes a substantially planar hub member to which a plurality of interchangeable leg members are removeably attached. Moveable bushings are provided on the free ends of the leg members whose positions may be selectively adjusted to properly align and position the lamp shade on a conventional harp and in proper relationship to the lamp itself.
