Description

The invention relates to a set for a lampshade comprising an at least partially translucent cover for the lampshade, the cover being made of a flexible material, and wherein the cover has at least two rod-shaped welts and at least one frame element for the lampshade, the cover with the The frame element is releasably connectable and the frame element has, at least in sections, two recesses arranged at a distance from the edge of the frame element, the recesses being designed to receive the rod-shaped welts.

For various reasons it is desirable that lampshades are supplied with a cover made of a flexible material in the form of a set consisting of assemblable individual parts. This makes it possible, for example, that such sets for lampshades can on the one hand be stored at the dealer in a space-saving manner and on the other hand can be easily delivered to the end user. The assembly should be as simple as possible for the end user.

The GB 563,294 A describes a connection system for a lampshade, wherein flexible cover elements are clamped between curved connecting pieces. The casing elements made of plastic are L-shaped at the edge. These edge elements are pushed into the connecting pieces, which have corresponding recesses for this purpose. To assemble a lampshade, several cover elements and connectors are necessary. The shape of the lampshade results from the curvature of the connecting pieces.

The DE 20 314 027 U1 relates to a lampshade, the shell of which is flat when not assembled and the lampshade only through the construction-related clamping of the shell elements receives its shape. The ends of the casing elements are fixed in support rods with a longitudinal groove with the aid of a metal rod attached to them and held in this position by means of an upper ring and a lower ring.
The DE 20 2013 008 404 U1 shows a lampshade with a cover made of a flexible plastic material, which can be stretched between at least two support structures, wires or ropes being used for stretching.

Disadvantages of the prior art are, on the one hand, the insufficient stability of the holder of the flexible covers or cover elements and, on the other hand, the low variability with regard to the shape of the lampshade.

The object of the present invention is to avoid these disadvantages and to provide a set for a lampshade with which a more stable mounting of the cover or of or cover elements is possible and which enables a high degree of variability with regard to the shape of the lampshade.

This object is achieved by a set for a lampshade with the features of claim 1.

The set according to the invention for a lampshade comprises an at least partially translucent cover for the lampshade with the purpose that light from a lighting means arranged within the cover is attenuated by the cover in order to avoid a dazzling effect. The cover has at least two rod-shaped welts which are used to fix and hold the cover in the assembled state of the lampshade. The welts also have a shaping function.

Furthermore, at least one frame element is provided for the lampshade, the cover being releasably connectable to the frame element in order to provide a to enable easy assembly and non-destructive disassembly. The frame element has, at least in sections, two recesses which are arranged at a distance from the edge of the frame element. The recesses are designed to accommodate the rod-shaped welts. It is also conceivable that several cover elements are provided, each of which has two welts that can be fixed in several frame elements, each with two recesses.

According to the invention it is provided that the frame element has a groove for each of the recesses, which extends from the recess to the outside of the frame element, the shell being connectable to the frame element in such a way that the shape of the lampshade in the assembled state through the angle of the grooves is determined relative to the outside of the frame element. That section of the frame element in which the recesses and the grooves are arranged thus functions as a welt rail, that is to say each of the recesses, together with the associated groove, forms a tensioning mechanism into which a welt is inserted.

The groove is used for the arrangement and alignment of the casing material adjoining the welts. This ensures that the casing is held in a particularly stable manner in the frame element. Since the shape of the lampshade in the assembled state is determined by the angle of the grooves relative to the outside of the frame element, it is possible to produce a differently shaped lampshade with the same shell simply by replacing the frame element with another frame element in which a different one Angle of the grooves is present relative to the outside of the frame element. This makes it possible with simple means to produce a completely different looking lampshade, but which has the same cover. This is particularly advantageous when the case is a case made from a noble material.

In particular, both a hanging, wall or ceiling lamp as well as a floor or table lamp can be produced with a cover. It is only necessary to select an appropriate frame element. In addition to the recesses and the grooves in the frame element, the welts give shape and fixation for the lampshade and allow numerous options in terms of design, function, but also logistics and yield of the lampshade, which can be assembled from the set according to the invention. As mentioned, the piping can represent different shapes of lampshades with one function and ensure maximum diversity for all kinds of people. The welts and the frame elements with the recesses and the grooves that act as welt rails are therefore essential.

Additionally or alternatively, it is possible to retain the frame element and to fix a differently colored, made of a different material and / or a differently shaped cover in the frame element in accordance with the desired lighting situation. This not only gives you a lampshade with a different shape, but generally with a different design. The piping function offers a tensioning mechanism with the piping and the frame element functioning as a piping rail. The piping function, that is, the possibility of fixing the cover made possible by the piping and the frame elements with the recesses and the grooves, thus serves both as a suspension and stabilizer and as a shaping component of the lampshade.

It is preferably provided that the cover has a respective piping at both ends of the cover. The shell can thus be stretched in a single frame element by introducing both welts into the recesses arranged in this frame element. However, several frame elements can also be provided, the cover consisting of individual cover elements, each of which has two welts. In these In some cases, the lampshade is only stretched through the arrangement of all piping in the associated recesses.

Both the recess and the groove can be milled. The recess serves as a guide rail for the welts. The groove serves as a guide rail for the areas of the shell or shell elements adjoining the welts.

Further advantageous embodiments of the invention are defined in the dependent claims.

In one embodiment of the invention, at least one of the recesses, preferably all of them, is designed as a blind hole. This can be particularly advantageous in the case of wall or floor lamps when the frame elements have a large longitudinal extension, but the cover of the lampshade is only to be arranged in a certain area of the frame element. A blind hole automatically sets a limit for the position of the inserted piping. It is not necessary to use a separate delimitation or stop element.

In a preferred embodiment of the invention, the welts have at least partially a circular cross section. In this case, the recesses can be designed as cylindrical bores, also with an at least partially circular cross-section. Edges with a completely circular cross-section can be used particularly easily in various frame elements of the set according to the invention, the grooves of which assume different angles relative to the outside of the frame element. Alternatively, welts with an only partially circular cross section can also be used for the invention. For example, it is conceivable that the welts at least partially have a semicircular cross section. This can be sufficient to ensure the fixing function of the piping rail for the piping.

It is preferably provided that the welts are designed to be rigid, for example in that the welts are made entirely or at least partially from wood. With a cover of the lampshade made of a flexible material, rigid welts can ensure a particularly stable connection between the welts and the frame element, which improves the function of the tensioning mechanism.

In one embodiment of the invention, the welts and / or the frame element are wholly or at least partially made of wood. Wood is an organic material that is particularly popular in living spaces. Various types of wood are used here.

It can be provided that the casing is made entirely or at least partially from an organic material. This also increases the quality of the lampshade. A wide variety of materials are conceivable here, such as, for example, casings or casing elements made from hay, wherein a wide variety of blossoms or flowers, such as rose petals or cornflowers, can be applied to the casing or casing elements for decorative purposes. Other organic materials, such as. B. moss, cork, pineapple leather, stone veneer or flax are possible. In principle, the sheaths or the sheath elements can also be made of other flexible materials, such as, for. B. be made of a textile material. Materials with sufficient inherent rigidity can be used directly for the shell. Materials that have too little inherent rigidity can be laminated onto suitable materials such as wood veneer.

In one embodiment of the invention, the set also has a luminous body that can be attached to the frame element, the luminous element being designed and / or attachable to the frame element in such a way that the luminous element, when attached, forms further recesses and / or further grooves in which the welts can be arranged.

In this case, two-part recesses and two-part grooves are available for the welts, a first part of the recesses and / or the grooves being arranged in the frame element and a second part of the recesses and / or the grooves being formed by the luminous body attached to the frame element. The further recesses and / or the further grooves can extend the recesses and / or the grooves of the frame element upwards or downwards.

It can be provided that the further recesses and / or the further grooves are arranged in the luminous element. Alternatively, it can be provided that the further recesses and / or the further grooves are only formed by the arrangement of the luminous element on the frame element - that is, between the luminous element and the frame element.

The luminous body can comprise a cooling body and a lighting means, wherein the cooling body in the attached state can form the further recesses and / or the further grooves for the welts. The further recesses and / or the further grooves can be formed between the cooling body and the frame element. The illuminant can be arranged on the heat sink.

A wide variety of shapes are conceivable for the cover, in particular rectangular, trapezoidal or semi-ring-shaped covers can be used in the flat state. In particular, those edges of the covers or of the cover elements on which no welts are arranged can be designed freely. The cover can have individual cover elements, each of the cover elements having two welts.

In one embodiment of the invention, the frame elements, which function as a welt rail, have exactly two recesses and exactly two grooves.

The welts can consist of a first part and a second part. The cover or the cover elements can be used between the first part and the second part of the welts. For example, the first and the second part can be clamped together by means of a clamping device. It is also conceivable to glue the first and the second part of the welts onto the cover or the cover elements and thereby assemble the welts.

The invention further relates to a lampshade which is produced or assembled from a set as described above. The lampshade thus has an at least partially translucent shell and / or several at least partially translucent shell elements, the shell or the shell elements being or are made from a flexible material and the shell having at least two rod-shaped welts. In the case of a plurality of cover elements, each cover element has at least two rod-shaped welts. The lampshade further comprises at least one frame element, the cover or the cover elements being or are releasably connectable to the frame element. The frame element is designed at least in sections as a welt rail. Thus, at least in sections, two recesses are provided which are arranged at a distance from the edge of the frame element and are designed to receive the welts. Furthermore, each of the recesses has a groove which extends from the outer recess to the outside of the frame element. The cover or the cover elements can be connected to the frame element in such a way that the shape of the lampshade in the assembled state is determined by the angle of the grooves relative to the outside of the frame element.
