Contractile folding lampshade

Abstract

A kind of lampshade which can be contracted and folded comprises of an upper support ring, a lower support ring, a piece of lampshade cloth inbetween, and some detachable bracing pieces with the functions of connection and supports, on the exterior side of the cloth. In the centre of the upper ring there is a fixed seat supported by radical rods. The bracing pieces made from elastic material are put in decorative cloth or lace sheathing, one end of the bracing piece is flexibly articulated to one of the rnigs, the other end is inserted in a detachable way into the locating slot or hole in the other ring. By moving the bracing pieces from the interior side to the exterior side of the lampshade cloth, the present invention makes it possible to have a wide variety of lampshade cloth and shapes, good halation effect, no shadow of the bracing pieces, simple structure, simplified processing and assembling procedures, etc..

Description

Technical field [0001] The invention relates to a lampshade for lighting lamps, in particular to a collapsible and foldable lampshade for table lamps, floor lamps, bedside lamps, chandeliers and other lamps. Background technique [0002] There are two main structural forms of lampshades on the market. One is a traditional conventional lampshade, with upper and lower support rings, and a longitudinal connection between the two support rings, support ribs or rods. The support rings or ribs and rods can be decorated with cloth or paint, and the support ring and ribs or rods are non-removable. The lampshade frame is laid or covered with decorative lampshade cloth according to the design requirements. The center of the upper support ring is provided with a fixed seat supported by a radial rod. The fixed seat or the radial rod of the fixed seat is provided with a lamp holder The connected bracket has a simple structure, strong connection and high strength, but its shortcomings of takin...

AI Technical Summary

Problems solved by technology

For example, the structure shown in Chinese Patent No. ZL00261113.9 "Lampshade", although this structural form solves the shortcomings of large lampshade volume and high transportation costs during transportation, but because the supporting ribs or rods are located on the inner side of the lampshade cloth, it is difficult to assemble and disassemble. It is laborious and inconvenient. The fabric quality of the lampshade is vulnerable to potential damage, and the fabric fibers are prone to fatigue relaxation and elongation, causing the tension of the lampshade fabric to gradually decrease or even partially collapse, the overall shape is damaged, and the service life is short.

Chinese Patent No. ZL01201772.8 "A Detachable Lampshade" also discloses a foldable lampshade with supporting ribs or rods located inside the lampshade. Positioning device for insertion and positioning of support ribs or rods. The appearance shape of this lampshade is determined by the bending and distribution of the support ribs or rods. The processing requirements for the support ribs or rods are relatively high, and the shape change is difficult. If it is impossible to make special-shaped lampshades, the cost It is also improved accordingly, and it is not easy to assemble

Chinese Patent No. ZL99238729 "Foldable Lampshade" discloses a foldable support rib or rod with upper and lower sections, which has a complex structure and high cost; the support rib or rod needs a large space for easy bending, forcing the support rib Or there is a large gap between the rod and the lampshade cloth, the overall feeling and overall strength are poor, and the lampshade cloth loses support, resulting in low durability

In addition, the above-mentioned lampshade products are all low-grade products, and the lampshade cloth is mostly in the form of a layer of elastic cloth attached to the inner side of the decorative cloth. For the problem of heavy shadows, some products are equipped with longitudinal decorative strips at the positions corresponding to the surface of the lampshade cloth and the supporting ribs or rods, but after folding and long-term transportation, the decorative strips will appear to fit, Deformation or even wrinkling, cloth strips falling off, and folding wrinkles on the decorative strips after unpacking and installation cannot be eliminated, making the lampshade a defective or waste product
