Filed: 2001-04-09
Abstract: An improved structure foldable assembly-type lamp shade comprised of a top ring at the uppermost end of the lamp shade, a bottom ring of larger circumference than the top ring, and frame members propped between the top ring and the bottom ring. The bottom ring has fixing mounts consecutively disposed at the frame member locations that provide for the assembly and positioning of the frame members, with the fixing mounts at the support member installation locations having different type connection sections based on the respective type of fixing mount arrangement utilized. When packaged, since the frame members can be first folded down and whorled into a flat state such that the frame members and the top ring are stacked on the bottom ring, the lamp shade of the present invention occupies the smallest physical assembly area to facilitate ease of assembly and, furthermore, the resulting minimized storage area effectively reduces shipping costs.
