Description

A kind of contractile folding lampshade

Technical field

The present invention relates to a kind of lampshade of lighting lamp, be meant a kind of collapsible folding lampshade that is used for light fixtures such as desk lamp, floor lamp, bedside lamp, pendent lamp especially.

Background technology

Existing commercially available lampshade mainly contains two kinds of versions.A kind of is traditional conventional lampshade, has bracing ring up and down, and the vertical connection between two bracing rings, ribs or bar, bracing ring or rib, bar can be with decorations such as cloth or lacquers, bracing ring and rib or bar have been formed non-dismountable gallery, ornamental lampshade cloth is laid or be with to the appearance of frame by designing requirement, central authorities at the upper support circle are provided with the holder that supports by radial bars, the radial bars of holder or holder is provided with the support that is connected with lamp socket, this kind frame shape is simple in structure, be connected firmly, the intensity height, excessive shortcoming is also very obvious but it takes up room, greatly limited transportation, the performance of depot storage capacity, high even far away surpassing of cost of transportation produces, the summation of selling cost, the user is also very inconvenience when collection.In order to make full use of and to enlarge transport capacity and be convenient to collection, reduce totle drilling cost simultaneously, make retail price maintain one more on the reasonable levels, folding lampshade arises at the historic moment.The version of at present common folding lampshade is, ribs or bar all are positioned at the inboard of lampshade cloth, and the employing mode of being movably hinged is connected between one end and last or the lower support circle, and the other end inserts in the trepanning ad hoc on another bracing ring.For dismantling and assemble, ribs or bar expose outside more, are an incomplete product in fact.When lamp was bright, as do not install the decoration cloth additional on lampshade cloth, then the shade of ribs or bar will be shone upon on lampshade cloth by light, has greatly reduced the aesthetics of lampshade, finished product of low grade.As Chinese ZL00261113.9 patent " lampshade " structure of showing of giving, though this version has solved the shortcoming that the lampshade volume is big in the transportation, cost of transportation is high, but because ribs or bar are positioned at the inboard of lampshade cloth, assembling, dismounting i.e. effort are inconvenient again, lampshade cloth matter is vulnerable to potentiality injury, and it is loose and elongated that measuring fiber is prone to fatigability, causes lampshade cloth rate of tension to descend gradually even produces local collapse, moulded being damaged, service life is short.China's ZL01201772.8 patent " a kind of removable lampshade " also discloses the collapsible lampshade that a kind of ribs or bar are positioned at the lampshade inboard, its ribs or bar are trapezoidal shape, and positioner is set in the inboard of upper and lower bracing ring, for ribs or bar insertion and location, this lampshade face shaping is by the bending and the distribution decision of ribs or bar, processing request to ribs or bar is higher, the change of shape difficulty is as making special-shaped lampshade, the also corresponding raising of cost also is difficult for assembling.China's ZL99238729 patent " folding lampshade " discloses a kind of segmentation folding ribs or bar up and down, its complex structure, cost height; Ribs or bar need bigger be convenient to bend allow bit space, force the bigger gap of existence between ribs or bar and the lampshade cloth, associative perception and bulk strength are poor, lampshade cloth loses support and causes durability low.In addition, above-mentioned lampshade product all belongs to low grade products, the lampshade cloth forms of pasting one deck elastic force cloth in the inboard of bunting that adopt more, and lampshade cloth light transmittance height, the brace rod shade is heavy, and the light soften is low; In order to overcome the heavy problem of ribs or bar shade, the product that has installs vertical ornamental strip additional in the appearance of lampshade cloth and ribs or the corresponding position of bar, but after folding and long-time transportation, because of reason ornamental strips such as the temperature difference, extruding applying, distortion can occur even wrinkling, cloth comes off, the folding wrinkle of installing on the ornamental strip of back of unpacking can't be eliminated, and makes lampshade become substandard products or waste product.

Summary of the invention

The purpose of this invention is to provide a kind of simple in structure, processing is easy, assembling easily and the high collapsible folding lampshade of product specification.

Designed a kind of contractile folding lampshade according to above-mentioned purpose, comprise upper support circle, lower support circle, central authorities at the upper support circle are provided with the holder that supports by radial bars, being provided with lampshade cloth between upper and lower bracing ring is connected and the detachable ribs or the bar of supporting role with rising, this ribs or bar are positioned at the outside of lampshade cloth, and ribs or bar are enclosed within bunting cover or the lace cover.After the assembling, an end of ribs or bar is movably articulated on the bracing ring, and the other end is inserted in the positioning and plug-in mounting groove that is provided with on another bracing ring, the hole in dismountable plug-in mounting mode.This ribs or bar adopt elastomeric material such as raw material manufacturings such as spring steel, engineering plastics, and its effective length should be slightly larger than the distance between bracing ring up and down, and therefore assembling back nature is to lampshade axle chip bending and press or be close on the outer surface of lampshade cloth.Simultaneously, ribs or bar are advisable with the strip sheet material, also can adopt semicircle wire rod, are provided with the insertion head that is complementary with positioning and plug-in mounting groove, hole at its free end.

The present invention compared with prior art, ribs or bar are moved on to the outside by the inboard of lampshade cloth, make the selection range of lampshade cloth obtain sufficient expansion, the appearance of lampshade is more rich and varied, be beneficial to designing and developing of special-shaped lampshade, the ectonexine of lampshade cloth can adopt that to separate be gapped version in addition, played the effect of halation, make light softer pleasant, and avoided the generation of ribs or bar shade, and be enclosed within the outer sheathing of ribs or bar in addition and under any condition, can wrinklingly also can not come off, make the lampshade globality strong, attractive in appearance, top grade, the taste that has effectively improved value-added content of product and room internal environment; Whether because matting can cover in the position that is movably hinged of positioning and plug-in mounting groove, hole and brace rod naturally, therefore observing inside and outside the lampshade and all can't telling lampshade is folding lampshade; Because simple in structure, handling ease, assembling process are easy, the assembling yield rate of unpacking height effectively reduces the integrated cost of product; The ribs or the bar that adopt elastomeric material to make make lampshade cloth form graceful curve naturally, avoided existing product infringement because of repeatedly stretching by force and causing in dismounting and assembling process repeatedly to cloth matter with installation ribs or bar, guaranteed natural elastic lasting of cloth matter, improved the service life of lampshade, more the globality of product inside and outside integrative and product provides guarantee.
