Abstract
A lampshade folding structure to achieve minimum packing volume thus to reduce costs of packing material and transportation essentially comprised of a support frame to stretch up a soft shade between an upper and a lower rings; each ring provided with at least two pivoting devices so that when folded, both rings are folded into semi-circular shape and put on the same plane with the support frame removed to facilitate packaging, transportation, carriage and storage.
Claims4
A lampshade folding structure, essentially comprised of a shade made of soft materials, fixed to its top and bottom respectively an upper ring and a lower ring;
- a support frame between said upper and lower rings for stretching up the shade into a conic cape shade;
- a mounting hub provided at the center of the upper ring to connect the shade to a lighting fixture, and multiple links provided in radiation to connect between the hub and the outer circumference of the upper ring (1) to give better structural strength;
- characterized by that:
- said lower ring comprised of two semi-circular rings connected by at least two pivoting devices for the lampshade to reduce its dimension by removing the support frame, folding the lower ring into a semi-circular shape and putting both rings on the same plane, thus to reduce packing and transportation costs.
