Abstract

A rapid assembly and disassembly lamp shade structure comprised of a top ring, a bottom ring, and frame members propped between the top ring and the bottom ring. The bottom ring has aligned with the top ring support rod positions and extending from the center to its circumference slide rods and, furthermore, coupling rings capable of traveling back and forth along the slide rods are ensleeved onto the slide rods. Each coupling ring has projecting upward a hinge tab with a through-hole formed in it, the bottom ends of the paired brace rods of the frame members are punched into a flat shape and, furthermore, the fastening sections have an insertion hole formed in the center, thereby providing for riveted conjoinment of the frame member fastening sections to the coupling ring hinge tabs. Capable of traveling reciprocally along the slide rods, the coupling rings maintain the top ring and the bottom ring in a reinforced open state or are folded down such that the top and bottom rings are brought against each other in a closed state. As such, the invention herein achieves rapid assembly and disassembly and, furthermore, a reduction in material storage area that effectively lowers shipping costs.

Dependent claims

A rapid assembly and disassembly lamp shade structure comprised of a top ring, a bottom ring at the lowest aspect of a lamp shade, and frame members propped between the said top ring and the said bottom ring, wherein the said top ring has support rods extending from the center to the circumference and, furthermore, the said support rods are aligned with the said frame members at the circumferential edge of the said top ring and an inclosing space is formed by upward bending that provides for situating the top ends of the said frame members against the said inclosing spaces;

the said bottom ring has aligned with the said top ring support rod positions and extending from the center to its circumference slide rods and, furthermore, coupling rings are ensleeved onto the said slide rods, with the said coupling rings capable of traveling back and forth along the said slide rods;
each said frame member consists of a pair of brace rods, the separation of which is gradually reduced from a top rod such that the bottom ends merge and become flush, the bottom ends are punched into flat-shaped fastening sections and each said fastening section is aligned with one said coupling ring for conjoinment into a unitary structural entity;
as such, ease of assembly is achieved and, furthermore, the resulting minimized storage area effectively reduces shipping costs.
