Abstract

An ornamental flat plate type picture having a metallic layer on the surface of which are produced a series of relief type picture elements by means of depressions or protrusions worked into the metallic layer is constructed such that the metal layer has an at least partially transparent or translucent support layer, pref. epoxy resin, attached to the rear surface of the metal layer. The depressions used to construct the picture components are worked through the metal surface layer until they reach this lower translucent support layer.

Description

Ornamental, approximately plate-shaped structure The invention relates on an ornamental, roughly plate-shaped structure, which is a metal layer has, in the surface of which approximately relief-like image elements through at the image points or image-free areas in the metal surface made depressions and ablations of the metal are incorporated.

Ornamental structures of this type in the form of copper plates are known, Image elements, e.g. drawings, are sunk into the surface in the aforementioned manner are. The plane of appearance of these picture elements is thus an e.g.

flat surface. Such copper plates become finished works of art themselves and can be hung on a wall, for example, as a wall decoration or e.g. can be used as decorative tabletops. In making these copper plates The procedure is usually the same as for the production of metal plates, as the information carrier in printing technology for creating Prints called prints can be made. For example, the photo-technical Process for the production of such copper plates is known. Starting material for it is a relatively thick copper plate, the surface of which is a light-sensitive layer wearing.

From the template, e.g. a drawing, whose image elements are shown as positive or negatively transferred onto the latter by hollowing out the copper plate surface are to be, a slide is made by taking photos, depending on the design or created negative. The picture elements of the latter then become photographic Reproduction reproduced on the photosensitive layer of the copper plate surface, on which a corresponding latent image is then generated as a result of the exposure. This is followed by a chemical treatment of the surface of the metal plate. The latter is finally treated with chemical etchants, which ever either the image areas or the non-image areas depending on the desired design into the copper material by chemically dissolving and removing the copper on those Places are etched. Much the same procedure is used to make metallic Treated printing plates, of which impressions are made for the production of images should be.

Essential feature of these processes and those produced afterwards metal plates, the image elements created by deepening the xetal surface bear is that these depressions are not through the total thickness of the Xetallplatte go through it, otherwise the metal plate would disintegrate into individual pieces. A part the thickness in the back area of the metal plates is therefore not corresponding Provided indentations and therefore carries the integral therewith, which make up the picture elements Layer part on the front of the metal plates.

As a result, the metal plates have a relatively large plate cross-section and are therefore heavy and expensive because of the high amount of material used. To the Another is the pictorial impression made by the picture elements on the metal surface convey, relatively one-sided, because the picture elements are based solely on the structure the metal surface when viewed from the front with or without lighting the metal surface act from the front. The pictorial effect known from such ornamental structures is therefore relatively weak and not very effective. By these peculiarities are - despite an existing need - the design options very much narrowed with such known ornamental structures.

The invention is based on the object of an ornamental structure to create that requires little use of metal, therefore very light and is cheap, and especially with regard to the picture elements, a variety of picture effects and opens up creative application possibilities.

In the case of an ornamental structure, the task is the one mentioned at the beginning Kind according to the invention in that the metal layer on its surface opposite back an at least translucent, with the metal layer has firmly connected carrier layer and that the depressions, at least some of these, from the metal surface through the entire thickness of the metal layer up to are sufficiently incorporated into the carrier layer.

It is therefore already as a starting material, before the incorporation of the Image elements, for the later image carrier an approximately plate-shaped, flat or even Bent material with a carrier layer and a metal layer firmly connected to this before that then to incorporate the image elements according to conventional, Methods described at the beginning is processed, but in contrast to the latter the recesses penetrate the entire thickness of the metal layer, i.e. up to are led to the carrier layer. The layer thickness of the metal layer can be extremely small, e.g. kept in the order of 0.01 mm or slightly larger will. The carrier layer has the function of the carrier in the metal layer incorporated image elements. Thus, the use of metal material depends on the Choice of metal and size-deq structure can be extremely expensive, very small. The related material and cost price is correspondingly low.

Furthermore, the ornamental structures according to the invention are of weight extremely light. They can be extraordinary in terms of overall thickness be kept thin.

The total thickness can be in the order of 0.1 mm and of course can also be kept larger by increasing the layer thickness of the carrier layer as required is chosen accordingly with unchanged thickness of the metal layer. Thus can the ornamental structures according to the invention both as flexible films and as rigid plates are designed in itself. The design is also within this framework as a completely or partially convex and / or concavely curved film. Thus is the way for all possible shapes and creative uses of the ornamental Buildings opened up.

Due to the at least translucent design of the carrier layer In addition, a variety of image effects are achieved, which then unfold when before or above all a light source behind the ornamental structure according to the invention is available. Then the light shines in the area of the wells in the metal layer through the carrier layer. The course of the depressions brightly contrasts image elements from large image elements on the roof. This will be whole special, effective image effects achieved. If, on the other hand, this fluoroscopy is omitted, e.g. because, depending on the use of the ornamental structure, this does not exist at all is or the light source is not switched on, then the structure unfolds as well special, creative effects, because then the bottom of the indentations, through the surface of the carrier layer is formed, is colored according to the Property - the material of the carrier layer stands out from that of the metal layer running depressions, which are different according to the color of the metal Convey color impression. consequently, through the invention, there are many creative Possibilities opened up using the ornamental structure, namely in addition to using these structures as wall decorations. The structure can e.g. can be used as a plate or as a curved film, for example in lights, e.g. for round or square linear ceiling lights, whereby the ornamental structure the horizontal and / or inclined wall or at least a part this wall of the lamp bell itself forms or at least part of a translucent Wall of the lamp bell covered with the ornamental structure according to the invention is. Similar usage and design options are available for wall lights, Floor lamps or other types of lamps or lighting fixtures are possible. Even Furniture, e.g. tables, cupboards or the like, can with the inventive ornamental Structures can be occupied, or the latter can be done with an appropriately chosen thickness the carrier layer itself component of the furniture - z, B.

Be a cabinet door, wall unit, table top or the like.

The covering of objects with ornamental structures according to the invention has the particular advantage that the structures are completely finished for themselves can and aurwenorse in the manufacture of the objects that are occupied with these structures should be, no / tertigungssture for inaroeitung these structures is necessary. Household and decorative objects, e.g. made of glass, in particular vases, drinking glasses, Carafes etc. can be used with the structure according to the invention e.g.

be covered in film form. The creative application and uses are therefore almost arbitrary.

The use of book cases or book covers can also be considered and dachshunds. Another particularly appealing field of application is use on doors and / or windows, be it translucent or non-translucent material. In the case of these objects, the occupancy of an area also comes along the ornamental structure according to the invention into consideration. Extremely effective is for example the occupancy of glass doors or glass windows, e.g. in private buildings, public buildings such as schools, universities, concert and theater halls, museums, Churches etc. This also makes it a particularly easy option, for example opened up, church window by selecting appropriate, ornamental structures with to cover special motifs.

In an advantageous embodiment it is provided that the carrier layer consists of a translucent material. It can also be advantageous if the carrier layer is made of an anti-chemical etching of the metal of the metal layer resistant material. Here is the for the production of the invention ornamental structure currently possible etching processes are taken into account and a possible

Etching or through-etching of the carrier layer avoided.

It is advantageous if the carrier layer together with the metal layer is flexible or rigid in itself. The rigidity of the ornamental structure is essentially determined solely by the mechanical quality values of the material of the carrier layer and adjusted by their chosen thickness.

The metal layer, on the other hand, does not contribute to this. Rather, it will always kept as thin as possible, e.g. less than 0.1 mm, with orders of magnitude from 0.01mm to 0.035mm thickness are fully sufficient. So the backing layer is always at least as large as that of the metal layer.

As a rule, the thickness of the carrier layer is at least 5 times the thickness of the metal layer.

The carrier layer can be formed from a film or a fabric be. It is particularly advantageous if the carrier layer is made of plastic material is formed. So-called plastic-paper-foils, for example, come into consideration, Plastic fabric, fiberglass or the like. The metal layer is on top of that Carrier layer laminated, preferably glued or pressed on. Advantageous it can also be when the metal layer is printed onto the carrier layer preferably e.g. as copper imitation paint. The material used for the backing layer is for example epoxy resin or at least one material that contains epoxy resin in Consideration. Epoxy fiberglass can be of advantage here. Of course you can other plastics, which are much cheaper, are also used.

The choice of material for the Metallachicht- is almost arbitrary and depends on the wishes in terms of value, price and achievable design of the buyer. For example, the metal layer can be made of copper, tin or stainless steel exist. It can also be advantageous if the metal layer is on its surface has a metallic coating, in particular tin-plated, chrome-plated, silver-plated or gold-plated or with another metallic combination, e.g. chrome-plated or nickel-plated and a combination thereof.

In a further advantageous embodiment it is provided that on the carrier layer, preferably on the side facing the metal layer At least one additional layer, in particular a colored layer, is arranged on the carrier layer which has a lower light permeability compared to the carrier layer. This ensures that such ornamental structures have an additional color effect can unfold without affecting the starting material and / or the production of the The structure and thus the structure itself are noticeably more expensive. This color effect can at least in the area of up to the color layer and carrier layer through the metal layer through the indentations come to unfold. In another embodiment The color layer can also be on the side facing away from the metal layer, i.e. on the back, the carrier layer may be provided. The color scheme of the additional layer is almost arbitrary. The black version results in the ornamental structure about the same pictorial effect as in the case of known ornamental structures at the beginning illustrated genus. several, different colored additional layers are also possible, e.g. to create mixed colors. In a further advantageous embodiment it is provided that the adhesive layer also forms the additional layer. This is e.g. realized when the adhesive layer, by means of which the metal layer on the Carrier layer is glued on, is applied already colored.

In a further advantageous embodiment, in the depressions, at least some of these, a filling layer, in particular a color layer 'arranged. The filler layer can be translucent.

The invention is shown below with reference to in the drawing Embodiments explained in more detail. Show it: Fig. 1 is a schematic Front view of a flat ornamental structure according to a first embodiment, FIG. 2 shows a section of the ornamental structure along the line II-II in FIG. 1, FIG. 3 shows a section corresponding to FIG. 2 of an ornamental structure according to a second embodiment, FIG. 4 is a schematic, partially sectioned side view a ceiling lamp, both the ornamental structure according to FIGS. 1 and 2 as a constructive Component is used.-In Fig. 1 and 2 is a first embodiment ornamental, approximately plate-shaped structure 1D shown, the substantially rectangular shape and in which a flat surface as a plane of appearance for something like a relief Picture elements 11 is used. The ornamental structure 10 has a metal layer 12 on, in the surface of which the picture elements 11 by at the picture locations or non-image Places in the metal surface made depressions 13 and removal of the metal are incorporated. On its back opposite the surface it has the metal layer 12 is an at least translucent, preferably translucent, with the metal layer 12 firmly, for example by gluing, connected carrier layer 14 on. The recesses 13, at least some of these, are so deep into the metal layer 12 incorporated that it extends from the metal surface through the entire thickness of the metal layer 12 extend up to the carrier layer 14. the Carrier layer 14 consists made of plastic material, e.g. in the form of a film or a fabric. The plastic material consists for example of epoxy silk. It is advantageous if the plastic material the carrier layer 14 resistant to chemical etching of the metal of the metal layer 12 is. Depending on the setting of the thickness of the carrier layer 14, the structure is ornamental 10 either flexible or inherently rigid.

The metal layer 12 is formed from copper, tin or stainless steel and laminated onto the carrier layer 14, preferably glued or pressed on. Also Printing, e.g. as an imitation copper color for copper, is possible.

The cross-sectional thickness of the ornamental structure 10 is in the illustration shown enlarged in relation to the natural size in Fig. 2. As layer thickness a thickness of 0.01 mm is generally sufficient for the metal layer 12. Possible are of course also stronger metal layers 12, for which, however, a thickness of 0.1 mm should not be exceeded, because on the one hand this is not necessary and on the other hand results in high cost and relatively large weight. The thickness of the Carrier layer 14, on the other hand, is significantly larger than that of the metal layer 12. It is at least five times the thickness of the metal layer 12. By the Choice of the thickness of the support layer 14 is the flexibility of the ornamental structure 10 set. The thicknesses for the carrier layer 14 are, for example, dimensions of 0.5 mm and larger are possible.

This specifies whether the ornamental structure 10 foil character and can therefore easily be bent like a foil, or the character has an approximately relisf-like plate.

The second exemplary embodiment shown in FIG. 3 differs from the first in that on the carrier layer 14, in the embodiment shown on the side of the carrier layer 14 facing the metal layer 12, an additional layer 25 is arranged, which is designed as a color layer and one opposite the carrier layer 14 lower Has light transmission. The additional layer 25 Iv is formed, for example, by the adhesive layer itself, by means of which the metal layer 12 is laminated onto the carrier layer 14. The adhesive layer is e.g. in colored black.

In another exemplary embodiment, not shown, the additional layer is on the back side of the carrier layer facing away from the metal layer 12, that is, its back side 14 / provided. Also several additional layers 25 between the metal layer 12 and the carrier layer 14 or on the back of the carrier layer 14 are possible.

In a further exemplary embodiment not specifically shown shows the metallic layer 12 on its surface, that is to say that of the surface facing away from the carrier layer 14 Surface, a metallic coating. E.g. the surface of the metal layer 12- tin-plated, nickel-plated, chrome-plated, silver-plated or gold-plated being an advantage it can also be. if. what is not particularly shown ip to some, in open editions ä, zuminaest'von alesen, a filling layer, e.g. a translucent layer of paint, is arranged.

In the exemplary embodiment shown in FIG. 4, one of the multitude the design and application possibilities of the ornamental structure is a special one exposed. Fig. 4 shows a ceiling lamp 30, which is hanging on a horizontal Ceiling 31 is attached. The ceiling lamp 30 has a light bulb indicated, for example 32 with a socket for it or a support part carrying fluorescent tubes, not shown 33 and a lamp bell 34 detachably attached to the latter. Which are about At right angles to the ceiling 31 extending walls 35 of the Leuchtengiocke 34 exist Made of at least translucent, e.g. matt-screen-like plastic material.

On the side facing away from the ceiling 31 is the lamp bell 34 completed by a plate-shaped ornamental structure 36, which in the special The embodiment corresponds, for example, to that according to FIG. 1 or FIG. 3.

The plate-shaped ornamental structure 36 is on the in to the ceiling 31 facing away from the direction end faces of the walls 35 releasably attached, e.g. glued on. The layer thickness 14 of the carrier layer S of the ornamental structure 36 is selected here so that the ornamental structure 36 is approximately rigid in itself is, so not in the direction facing away from the ceiling 31 due to its own weight is deformed, for example sagging.

The lamp shown in Fig. 4 is also as a wall lamp on a vertical aligned wall mountable. In another embodiment, you can also the walls 35 formed by corresponding ornamental, inherently rigid structures be or at least be covered with such structures, e.g. in the form of a film.

When the light bulbs 32 of the ceiling light in FIG. 4 are switched on the light rays once through the translucent walls 35 to the outside and illuminate the corresponding room.

On the other hand, the light shines in the area of the depressions 13 in the Metal layer 12 through the carrier layer 14, so that the course of the depressions 13 in the case of the ornamental structure 36 is luminous from the other surface areas the metal layer 12 lifts off. This creates special effective picture effects This is also the case with lightbulbs 32 that are not singly switched.

About the area of application explained above with reference to FIG. 4 the ornamental structures according to the invention are also diverse due to the invention design possibilities opened up using such structures. These various options have been explained in detail at the beginning. So far is referred to.
