Double-shell lampshade.

The innovation relates to a double-shell Lampshade with a screen cover carrier as the inner screen and a screen fabric attached to it as an outer or Basket skin.

There are two basic ways to create lampshades in practice _Λ In the practical implementation of a production method, a wire frame is used in the well-known manner, which is formed from rings and struts that are welded together, then painted and then covered with a lampshade cover.

The second type of lampshade formation uses a plastic frame instead of a wire frame

existing surface planes, circular shell-shaped molded jacket, which grips around a wire ring for stabilization at the upper and lower end and on its outer surface a decorative fabric or the like. stretched. One such a type has become known from the documents of patent application A 21 087 VIIIcAb.

Lampshades made by means of a wire frame are formed, the lack of a complex production adheres, as well as those lampshades that are formed with a molded jacket stiffened by wire rings.

The task of the present innovation exists now in using an umbrella cover carrier according to the documents of the above-mentioned patent application, but still has the character of a wire rope lampshade to get, whereby the cheap production and the effective design of the lampshade are worth striving for The prerequisites for the subject of the innovation are.

The aim of the innovation is now first achieved in an advantageous manner essentially that the inner screen as inherently more rigid, free of metal stiffening rings, essentially hood-shaped, bell-shaped or similarly designed, self-supporting and preferably made of a flat, plate-shaped foil blank Embossed plastic support body with from the scope smante1 level emerging over the entire Circumferential area distributed, supporting body reinforcements representing, Point, line or similarly designed self-supporting elevation deformations is formed.

In its practical implementation, the object of the control has the advantage over lampshades with a wire frame that all the effort associated with the production of such a wire frame is eliminated because the support body can be produced by machine according to the innovation. Compared to a lampshade according to the ^{previous e 7} "-: Ahnten patent application, the new support body has the advantage of its self-supporting capabilities, which means that it does not have any stiffening

rings for stabilization are required.

All the advantages of the innovation are made possible by the self-supporting elevation deformations as support body stiffeners both in terms of stability, as well as in terms of appearance. The lampshade upholstery fabric acts on this elevation deformation When opened, the lampshade that is then created has exactly the same appearance as one with a wire frame Lampshade equipped as a reference support.

This is all the more apparent when the inner screen is essentially multi-pointed Star cross-section with radial in meridian planes running uninterruptedly from the center of the upper screen opening to the edge of the lower screen opening tcin continuous stiffening ribs forming, linear longitudinal elevation deformations is provided.

In this context, however, it is also possible to have the inner screen with

transverse elevation deformations representing stiffnesses Mistake.

In both of the aforementioned embodiments, a self-supporting body is formed, which fully meets all requirements. The elevation deformations act in addition to an extraordinary durability of the lampshade at the same time as an inner screen, what a Makes feeding the umbrella cover fabric dispensable.

As part of the innovation, it is now possible to use the support body, which is made from plate-shaped foil blank Is embossed to produce in a vacuum manufacturing process. So the practice is not to a specific one The shape of the lampshade is tied, but rather are there various shaping possibilities given. The new support body, which is a full replacement for a wire support frame offers, but can optionally also be produced in an injection molding process.

In summary, the innovation has succeeded in creating a completely new type of lampshade

create that can be produced by machine with the least amount of manual labor and thus not only particularly characterized by their cheapness, but also decisive in terms of the visual impression Bring advantages, as a result of which the new lampshade distinguishes itself decisively from previously known ones and not least because of this it has an extraordinarily high utility value.

An embodiment of the innovation is shown in the accompanying drawings; show:

in the connection area between the lampshade and one Lampshade support ring.

In the lampshade shown, 10 denotes a screen cover carrier as the inner screen and 11 denotes a screen cover material as the outer or decorative skin. The support body 10 is designed as an inherently rigid, metal stiffening ring-free, hood-shaped plastic body, the peripheral surface of which is provided with elevations 10a which form a support body stiffener. These surveys. 10a can - as is illustrated in the exemplary embodiment - extend uninterruptedly in the longitudinal direction of the screen from the upper screen opening 12 to the lower screen opening 13. The support body parts 10b in the area between the elevation deformations 10a are drawn inwards towards the center of the screen, so that in the ε x £ tensioned state of the cover fabric 11 the support body functionally and visually has the character of a wire frame known per se.

The upper screen opening 12 is delimited by a deformation 14 which is U-shaped in cross section

Last but not least, it goes without saying that the illustrated and described embodiment is only is to be regarded as a possible embodiment for the practical implementation of the innovation, however should in no way be limited to this alone, rather, within the scope of the innovation, in particular to the Design and the course of the supporting body reinforcements representing elevation deformations 10a possible.
