Abstract
Abstract A lampstand providing a stable and properly-oriented support for a lampshade, particularly one constituted by an oriental lantern formed by a collapsible paper shell having polar openings, each of which is bridged by a strut having a central loop. The stand includes a vertical pole carrying a bulb socket and a harp formed by a triad of arms which encage the bulb and interconnect upper and lower rings. The lower ring is secured to the pole and the upper ring supports an extension rod in axial alignment with the pole. The lantern is mounted on the stand to envelop the bulb, the upper loop being attached to the head of the extension rod, the lower loop engaging the pole at a point just below a resilient collar which embraces the pole and is shiftable to a position subjecting the lantern to tension to maintain the shell thereof in its fully expanded state. Extension rods of different length may be installed on the harp to allow for centering of the bulb for a range of shade sizes.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
196 words
A lampstand in combination with a lampshade in the form of a collapsible oriental lantern having a shell with polar openings, each bridged by a strut having a midpoint loop, said stand comprising: A a vertical pole; B a socket supported at the upper end of the pole for receiving a light bulb; and C a harp constituted by a symmetrical array of at least three wires arranged to encage said bulb and interconnecting a lower ring attached to said pole at a point below said socket and an upper ring in axial alignment with the pole: D a replaceable extension rod whose lower end is received in the upper ring and is supported thereby in axial alignment with the pole to provide a rod head at a selected height, the upper polar loop of said lantern being secured to said rod head, the length of the rod being appropriate to the size of the lantern; and E a resilient collar on said pole which engages the lower polar loop of said lantern and is shiftable to force the lower loop downwardly to tension said shell and thereby maintain the lantern in its fully expanded state.
