    Descriptive Report of the Invention Patent for ELEMENTS OF ILLUMINABLE DISPLAY, WELL AS A PROCESS FOR THE PRODUCTION OF SUCH ELEMENT OF DISPLAY.
    [001] The present invention relates to an illuminable display element, especially for a vehicle. Such display elements are used, for example, as baseboards, sills, frames or decorative elements. In addition, the invention relates to a process for producing such a display element.
    STATE OF THE TECHNIQUE [002] In vehicles and especially in motor vehicles, such as automobiles, display elements are usually employed which can serve quite different purposes. To improve the perception of the display elements, especially at night, they are mostly illuminable. Display elements are also often used especially in the field of doors and boot covers, for example, to characterize the height of the baseboard and / or to represent a brand. However, display elements are also present in vehicles in the form of operating elements, such as keys, for example.
    [003] An illuminable display element that features a decorative element with slits in the form of a label is shown in EP 2 295 293. A translucent sheet incorporated in the rear side of the decorative element grabs the slits and is illuminated there by means of lighting.
    [004] An illuminable component with a flat decorative element, which has an opaque region and a translucent region that can be illuminated by means of illumination, is shown in CH 702 730.
    [005] Especially in vehicles it is desirable that the attention of passengers and especially the attention of the driver are directed
    2/29 for certain display elements depending on the situation. In this case, it may be, for example, the keys of the emergency lights, which must be activated in the event of a strong braking of the vehicle, to alert mainly the following vehicles. The display elements for displaying warning notices, for example, to indicate a low level of gasoline or an engine defect, require greater attention on the part of the driver. However, it may also be desirable, for example, that the decorative elements and, especially, the thresholds in the region of the doors, the trunk or the center console are provided with graphic elements and are illuminable, for example, to call the attention to the manufacturer's brand. However, due to the presence, in general, of many display elements already illuminated in the vehicle, it becomes difficult to direct attention exactly to a particular display element.
    Exhibition of the Invention [006] An objective of the present invention, therefore, is to present an illuminable display element with a better visual perception capability. In order to achieve this objective, a display element is proposed, as shown in claim 1. Furthermore, in claim 15 there is presented a process for producing such a display element. Advantageous configurations of the invention are shown in the dependent claims.
    [007] Indications of location and direction, such as top, bottom, vertical, horizontal, up and down, must be understood below as referring to at least one elevation or recess configured in the display element. By definition, the - at least one elevation extends upwards, respectively the - at least one recess extends downwards. In this case, usually, the visible side of the display element is arranged at the top and the rear side is arranged at the bottom. Here it is irrelevant in what position and location the
    3/29 display element is effectively mounted on a vehicle, for example, in relation to the force of gravity.
    [008] Therefore, the present invention provides an illuminable display element, especially for a vehicle, featuring:
    [009] - a flat-shaped cover with a visible side, a rear side and at least one slot;
    [0010] - at least one graphic element that is predicted and / or projected on the visible side of the cover;
    [0011] - as well as a means of illumination that serves to illuminate the crack.
    [0012] In this case, the graphic element is surrounded at least partially by at least one slit in such a way that the graphic element is peripherally illuminable, at least partially, by the light of the lighting medium. The cover has at least one upwardly extending elevation, within which the graphic element is arranged above the - at least one - slot and / or the cover has at least one downwardly extending recess, within which the element graph is arranged below the - at least one crack.
    [0013] Due to the illuminable slit that surrounds, at least partially, the graphic element and, especially, that surrounds it at the edge at least partially or completely, the graphic element can be illuminated at least partially by the light of the lighting medium and, due to this, it is highlighted in the observer's perception compared to other display elements. The graphic element is specially framed by the light of the lighting medium. In the event that the graphic element is arranged, respectively configured, within an elevation, then, due to the slit below the graphic element, a visual effect such that the graphic element in comparison with the surface of the covering
    4/29 involves lifting to be lifted or even floating. In the event that the graphic element is arranged, respectively configured, within a recess, then, due to the slit above the graphic element, the visual effect that the graphic element acts recessed behind the part of the cover surrounding the recess results. Therefore, in both cases the graphic element appears especially as if it were loose from the surrounding cover. The visual effect thus generated leads to a more evident visual appearance of the display element. In this way, the display element draws the viewer's attention to itself, making the display element's perception capacity improved.
    [0014] The display element, which is usually also called a decorative element, is preferably designed as a decorative ruler, operating element, such as, for example, a key, and, especially preferably, as a threshold or a footer of a vehicle. In the case of the vehicle, it is preferably a motor vehicle and, especially preferably, a road motor vehicle. The display element can be provided inside and / or outside the vehicle. However, the illuminable display element can also be designed, for example, as a decorative ruler or an operational element of a household appliance, such as a refrigerator, a steam cooker, a washing machine, an oven , a stove, a dishwasher or a piece of furniture.
    [0015] The feature according to which the roof is projected in a flat shape means that the roof is dimensioned substantially larger over two dimensions, especially four times larger, than over a third dimension, which generally extends perpendicularly the expansion of the surface on the visible side of the roof. The roof is designed, for example, in the form of
    5/29 track, especially as a track. Advantageously, the visible side of the cover has a basically flat region, which extends, at least partially, preferably totally, around the at least one graphic element. If several graphic elements are present, then, in addition, especially advantageously, this region will extend at least partially, preferably totally, also between the graphic elements.
    [0016] Generally, the - at least one - slot is designed as a continuous opening in the cover. Advantageously, this opening is surrounded laterally by the cover material. If there is only one gap, then it is usually projected in an elongated shape, with a longitudinal expansion along a substantially larger first direction, especially several times greater, than along a second direction that is, for example, perpendicular to the first direction. In this case, then, the slot is designed, for example, as a longitudinal hole or as a notch. In this case, that single crack involves the graphic element at least partially or completely. If several slits are present, then they are usually arranged in such a way that they wrap the graphic element together, at least partially.
    [0017] In the case of the graphic element, it can be, for example, a symbol, an ornament, a letter, an inscription or a logo. The graphic element can be formed, respectively molded, by at least a part of the cover. However, it can also be formed by at least one layer applied on the visible side of the cover. The - at least one - layer is applied, for example, through printing, vapor deposition, as, for example, through spraying, or through gluing. However, the graphic element can also be formed by stamping or by laser on or on the visible side of the cover. In addition, it can
    6/29 be formed, at least partially or even totally, through a raised structure configured especially in the roof. The relief structure is then arranged within the elevation, respectively of the recess, although in relation to this it preferably represents an independent autonomous structure, which, especially in a direction perpendicular to the expansion of the surface on the visible side, is dimensioned substantially less than the elevation, respectively recess. The height of the relief structure, understood as the maximum expansion of the relief structure along the vertical direction, respectively along the direction perpendicular to the visible side of the roof, is preferably at most of the same dimension, preferably at most one tenth of the dimension and, most preferably possible, at most one fiftieth of the dimension of the vertical height of the elevation, respectively of the recess, that is, the expansion of the elevation, respectively of the recess, along the vertical direction. Within the relief structure, a material can be provided, whose color and / or surface structure differs from the roof material. This material can be inserted into the embossed structure, for example, in the region on the visible side.
    [0018] According to a form of development of the invention, the illuminable display element has a total thickness, respectively a longitudinal expansion, in the vertical direction of 15 millimeters or less. If the graphic element is formed by an embossed structure, it can have, for example, a vertical height of 2 millimeters or less, although preferably 1.5 millimeters or less; more preferably 1 millimeter or less; still more preferably 0.5 mm or less, and most preferably 0.25 mm or less.
    [0019] According to a form of development of the invention, the means of illumination is arranged in the region on the rear side of the cover
    7/29 tura.
    [0020] In the case of the lighting medium, it may be, in particular, one or more light emitting diodes, which are preferably arranged in the region on the rear side of the roof. It is also possible, for example, a luminescent sheet, especially an electroluminescent or OLED sheet, or an incandescent lamp.
    [0021] Preferably, the cover is designed in one piece in its entirety. Because of this, the display element can be easily produced and has a visually attractive shape. Preferably, the cover is produced from a metal, such as, in particular, aluminum, steel or refined steel. However, it can also be produced from a synthetic material or another material such as wood, for example. The cover is configured, for example, in the form of a band, respectively as a band. In the case of metal or synthetic material, the cover is, for example, a flexible sheet or a self-supporting component. In the case of metal, a self-sustaining component is, for example, a metal plate. If the cover is made of synthetic material, then the cover may be at least partially translucent. According to a form of development of the invention, the cover has a thickness of one millimeter or less. The wood mentioned above is produced, for example, insofar as the wood is arranged in an autoclave and water vapor is introduced into the autoclave, which acts on the wood. After removing the steam-processed wood from the autoclave, the processed wood is molded and then dried.
    [0022] Preferably, the elevation and / or the recess is surrounded largely and especially entirely by at least one crack. If several elevations and / or recesses are present, then these will be surrounded, preferably together, largely and especially totally, by at least one gap, and
    8/29 especially preferably even the individual elevations and / or recesses are surrounded individually, largely and especially totally, by at least one gap. This results in a particularly attractive appearance of the display element, since the graphic element then appears as framed.
    [0023] Advantageously, the elevation has an upper surface, especially a surface as high as possible, respectively the recess has a lower surface, especially a surface as low as possible, within which the graphic element is arranged, and which is projected basically in flat form. However, the upper surface, especially the upper surface, respectively the lower surface, especially the lower surface, can also be designed, for example, in a convex or concave shape or can also have another shape. The elevation, respectively the recess, furthermore preferably presents a basically surrounding lateral surface, which extends from that upper surface, especially the highest possible surface, in the downward direction, respectively from that lower surface, especially surface as low as possible in the upward direction. In this way, the lateral surface connects the upper surface, especially the highest possible, respectively the lower surface, especially the lowest possible, with that region of the covering that involves the elevation, respectively the recess. Preferably, in this embodiment, the - at least one slot is disposed within that side surface. With regard to the upper surface, especially the highest possible, respectively the lower surface, especially the lowest possible, the light radiated by the means of illumination is then radiated laterally through the - at least one - slit, in the direction for fo
    9/29 ra. This results in a particularly attractive and evident visual effect. The elevation, respectively the recess, can be projected in the form of a pyramid trunk or cone trunk. Advantageously, the upper surface, especially the highest possible, respectively the lower surface, especially the lowest possible, is designed as a polygonal surface, such as, for example, a rectangular or square surface or as a circular surface.
    [0024] Regarding the graphic element, if it is a number or a letter or a symbol or an ornament or a logo, then, advantageously, at least one elevation, respectively at least one recess, is provided for each graphic element, that is, for each number, respectively for each letter, respectively for each symbol, respectively for each ornament, respectively for each logo. However, a general registration can also be provided for within a single elevation, respectively recess.
    [0025] The - at least one - slot can be arranged inside and / or outside the elevation, respectively recess. However, according to one embodiment of the invention, the - at least one - slit is disposed within a lateral surface of the elevation and / or within a lateral surface of the recess.
    [0026] According to a form of development of the invention, the at least one - slit is arranged outside the elevation, in a part of the cover that involves the elevation, preferably surrounding it by the edge. According to a form of development of the invention, the at least one - slot is disposed outside the recess, in a part of the cover that surrounds the recess, preferably surrounding it by the edge.
    [0027] According to a form of development of the invention, at least one - slit is arranged in a region lower than he
    10/29 vation in the transition region from a lateral surface of the elevation to a part of the covering that involves the elevation, preferably surrounding it by the edge. According to a form of development of the invention, the - at least one - slit is arranged in an upper region of the recess in the transition region from a lateral surface of the recess to a part of the cover surrounding the recess, preferably surrounding it by the edge.
    [0028] According to a form of development of the invention, the at least one - slit is arranged within a lift that at least partially surrounds the elevation, preferably surrounding it by the edge and / or within a groove or channel that surrounds at least partially the elevation, preferably surrounding it by the edge. According to a form of development of the invention, the at least one - slot is arranged within a lift that at least partially surrounds the recess, preferably surrounding it by the edge and / or within a recess that at least partially surrounds the recess , preferably surrounding it by the edge.
    [0029] According to one form of development of the invention, the - at least one - slit is arranged within a region of the roof, which is inclined in the direction of the elevation in such a way that the elevation is irradiated laterally by the light of the means of lighting. Preferably, the laterally irradiated elevation then has a lateral surface which with the mentioned region of the roof forms an angle of at most 120 Q , preferably at most 90 Q and particularly preferably at most 60 Q. Such a configuration of the display element can be achieved, for example, insofar as, bordering the elevation, a channel or a groove is formed, at least partially around it in the roof, and where - at least one - slit is provided in a region of wall of this channel, respectively groove, disposed distant laterally from the elevation
    11/29 tion. Instead of a channel or groove, a roof can also be formed that extends at least partially around the elevation, and the - at least one - slit is then placed laterally in the region of a wall region of the survey arranged close to the elevation. In this embodiment, the - at least one - slit is preferably arranged, respectively, formed so that the light that passes through the slit in a perpendicular direction, falls directly on a lateral elevation surface. In this way a special visual effect is formed.
    [0030] In a form of development of the invention, the - at least one - elevation and / or the - at least one - recess is designed in such a way that, due to its shape, it forms the graphic element. Advantageously, in this form of execution, the elevation, respectively the recess, presents a basically flat surface, whose profiles correspond to those of the graphic element. However, this elevation surface, respectively of the recess, can also be projected, for example, in a convex or concave shape or it can also have another shape.
    [0031] According to a form of development of the invention, the elevation and / or the recess may have at least one recess illuminable by means of lighting, which recess is configured in such a way that it forms the graphic element at least partially, preferably totally. Advantageously, this recess is illuminable by means of illumination in such a way that the graphic element itself visually constitutes a lighting element, making it substantially improve the identification of the graphic element in the dark.
    [0032] Preferably, the display element, at least in the region of - at least one - slot, has at least one support layer that is arranged on the rear side of the cover. If he
    12/29 display will also have a recess, so this support layer will preferably be arranged in the region of this recess on the rear side of the cover. In this case, the backing layer can especially grip the - at least one - slot, respectively in the recess, if present. Especially if at least one - slot completely surrounds the graphic element, the support layer can serve to support, respectively, retain the part of the cover provided by the graphic element. If the graphic element is formed by means of at least one recess in the roof and, in addition, the graphic element presents regions in the form of islands, such as, for example, occurring in the case of the letters A and B, unlike the letters C and M, then the support layer may also serve to support, respectively retain, the parts of the cover correspondingly formed in the form of islands. Preferably, these island-shaped parts are made of the same material as the remaining cover, although they can also be made of another material. Preferably, the cover, together with the - at least one backing layer, forms a composition of at least two layers.
    [0033] According to a form of development of the invention, at least in the region of - at least one - crack, on the rear side of the cover, there is placed - at least one - leaf that grips, especially at least partially, in the - at least one crack. If the cover has a recess, then, advantageously, this sheet will also be placed in the region of this recess, on the rear side of the cover and, in a particularly advantageous way, it will grip that recess. Preferably, the cover, together with the - at least one - sheet, forms a composition of at least two layers. Through this sheet, the display element can be sealed away from impurities, such as dirt and water. Second
    13/29 a form of development of the invention, at least in the region of at least one - slot, on the rear side of the cover, is installed - at least one - sheet, at least in the region of at least one - slot , on the back side of the sheet, at least one support layer is placed. Preferably, the cover, at least one - sheet and - at least one - backing layer form a composition of at least three layers. Due to the engagement of the sheet and / or the support layer in the - at least one - slot, it is possible to obtain an even more attractive visual configuration of the display element. For this, preferably, the sheet, respectively the support layer, grips the slot and / or the recess until the sheet, respectively the support layer, in the region of - at least one - slot and / or recess, is aligned with the visible side bordering the cover. If an island-shaped region is embedded in the sheet, respectively, then preferably the island-shaped region will be aligned with the visible side bordering the roof. Preferably, the sheet fills the slot at least partially, preferably completely. The sheet is, in particular, a sheet of synthetic material. This can be colorless, respectively white, or colored. Through sheets of colored synthetic material it is possible to produce colored graphic elements. The sheet may be one or more layers. A form of execution with several sheets is possible, which are the same or different. According to one embodiment of the invention, the sheet is, at least by regions, translucent, respectively at least partially transparent to visible light. According to one embodiment of the invention, the sheet has a thickness in the range of 1 millimeter to 0.05 millimeters, preferably 0.1 millimeter to 0.3 millimeters. The sheet is produced, for example, from ABS, polycarbonate or PMMA.
    [0034] To awaken a unitary visual impression, the layer of
    14/29 support and / or the sheet preferably presents at least in the region of the crack and / or in the region of the recess, if present, a surface coating that produces at least approximately the same visual impression as the material of which it is cover is produced. Because of this, in daylight, when the display element is not illuminated, the - at least one - slot, respectively recess, is less recognizable to the viewer, making the display element generate an attractive and more unitary impression for the Watcher. In that case, the sheet can be specially metallized.
    [0035] Preferably, the backing layer and / or the sheet are designed respectively to be translucent at least by regions. Advantageously, in addition, the backing layer and / or the leaf constitute a light conductor which serves to direct the light radiated by the illumination means into the - at least one - crack. In this case, the means of illumination can be arranged especially in such a way that the radiated light can reach the - at least one - slit exclusively by an indirect path, that is, via reflections, from the means of illumination. Correspondingly, advantageously, in the light conductor, reflection elements are provided that are designed and arranged in such a way that the light guided into the - at least one - slot changes its direction at least once. The backing layer and / or the sheet can also be designed especially as a diffuser, to disperse the light radiated by the illumination medium. Then, preferably, below the support layer and / or the leaf is a light conductor, from which the light is decoupled to the diffuser. Preferably, the lighting means is at least partially embedded, preferably basically completely, in the light conductor and specially shaped by the light conductor. This allows for a particularly compact construction of the display element.
    15/29 [0036] According to one form of development, the support layer is translucent, at least by regions, respectively at least partially transparent, for visible light. The backing layer can be produced from synthetic material, preferably from thermoplastic material and / or from hard plastic material. Advantageously, the support layer has a thickness of 1 millimeter or more. Preferably, the - at least one - support layer has a maximum thickness of 10 millimeters. If the - at least one - support layer is produced from thermoplastic synthetic material in an injection molding process, then the - at least one support layer will preferably have a maximum thickness of 10 millimeters, since with such a thickness, it is still possible to quickly cool the support layer after its production.
    [0037] According to a form of development of the invention, a protective layer such as, for example, a leaf is arranged on the visible side of the cover, at least by regions, preferably on the entire surface. Preferably, the protective layer can be removed from the visible side, especially manually. Preferably, the protective layer is transparent.
    [0038] In addition, a process is proposed for the production of an illuminable display element with a graphic element, especially an illuminable display element as presented above, presenting at least the following steps: [0039] - availability a flat roof;
    [0040] - formation of at least one elevation that extends upwards and / or at least one recess that extends downwards in the cover by molding the cover;
    [0041] - as well as formation of at least one crack in the roof.
    [0042] The elevation and / or the recess is projected, respectively
    16/29 arranged in such a way that the graphic element is arranged within the elevation, respectively of the recess. The graphic element and the - at least one - slot are designed and arranged in relation to each other in such a way that the - at least one - slot, in the case of an elevation, is located below the graphic element and, in the case of a recess, be placed above the graphic element and surround it at least partially.
    [0043] The second step mentioned, related to the configuration of an elevation, respectively recess, as well as the third step mentioned, related to the configuration of at least one crack, can be performed arbitrarily in the presented sequence or also in the inverse sequence.
    [0044] The molding of the cover can be obtained, for example, by means of a deep embosser, stamping, for example by means of a die and a punch, or hydromoulding. In addition, the process advantageously presents the stage whereby, especially by applying plasticized material, especially synthetic material, under pressure, such as, for example, through injection molding or extrusion, a layer of support at least by regions on the rear side of the cover, preferably at least in the region of - at least one - slot, even more preferably on the entire rear side of the cover, as well as in the region of at least one - slot.
    [0045] Preferably, by applying plasticized material, especially synthetic material, under pressure, such as, for example, through injection molding or extrusion, a support layer is placed at least by regions on a sheet arranged on the rear side of the cover, preferably at least in the region of - at least one - crack.
    [0046] According to a form of development of the invention, the support layer is placed under pressure on the rear side of the cover in such a way that, due to that pressure, the - at least one - elevation and / or o - at least one - recess is formed in the cover. In this way, the production process becomes particularly easy and economical.
    [0047] According to a form of development, the support layer is placed on the rear side of the cover in such a way that the support layer grips at least partially in the - at least one - slot. In addition, a sheet can be provided between the cover and the backing layer. The sheet and / or the backing layer can be placed on the back side of the cover, for example by means of a glue or an adhesive.
    [0048] According to a form of development of the invention, the illuminable display element, especially the support layer, has fixing means for fixing the display element on a vehicle surface, especially for fixing it on a body surface.

    Description of Preferred Forms of Execution [0070] Figures 1 and 2 show a first form of execution of an illuminable display element according to the invention. Figures 3 to 20 show other forms of execution and variants of illuminable display elements according to the invention. The same or similar elements of the display element are marked by the same reference number in the different forms of execution. In the case of the display elements shown in figures 1 to 20, it may be especially decorative rulers, thresholds or skirting boards, which are installed especially on vehicles.
    20/29 [0071] The display element shown in figures 1 and 2 has a cover 1 that is flat as a whole, with a visible side 10 that can be seen in figure 1, as well as with a rear side 11.
    [0072] The cover 1 has two elevations 12 that extend upwards. These elevations 12 are projected respectively in the form of a pyramid trunk and have, respectively, an upper surface 120 in a flat form, as well as a lateral surface 121 which extends from there, in a surrounding manner, downwards. In that case, the side surface 121 expands slightly downward. Within the upper surface 120 a recess 20 is configured respectively, which forms a graphic element 2 in the form of the letter A, respectively C. Of course, the recess 20 could also have the shape of any other letter, of an inscription, of a number, an ornament, a symbol or any other graphic element.
    [0073] In the present example of execution, one of the graphic elements 2, namely, the one that represents the letter B, presents a region 23 in the shape of an island, that is, a region that is completely surrounded by graphic element 2. In this region 23 in the form of an island, the cover 1 has an additional recess. Within the upper surface 120 other recesses may be present, such as, especially, in the region between the two legs 24 formed by the letter A, such that the recesses cover a large part of the surface content in relation to the upper surface 120.
    [0074] Inside the side surfaces 121 are respectively configured slits 14, which are in the form of grooves. In the case of elevation 12, shown in figure 1 on the left side, with the graphic element 2 in the shape of an A, four slits 14 are present, which together involve at least partially the graphic element 2. On each of the four sides of elevation 12 in
    A slit 14 is arranged in the shape of a cone trunk. It is even possible to provide for a greater number of slits 14, which together involve a graphic element 2, and which are respectively separated from each other by a connecting bar 15, as shown in figure 3. Preferably, these slits 14 are arranged at regular distances from each other. As shown on the right side of figure 1, in the case of the elevation with the graphic element 2 in the form of a C, a single surrounding slot 14 in the lateral surface 121 can be provided, which completely surrounds the graphic element 2, respectively the recess 20 Such a slit 14 is also shown in figure 4.
    [0075] The cover 1 can be produced, for example, of synthetic material, wood or, as in the present example of execution, of a metal like, especially aluminum or steel, especially refined steel. In this case, due to being produced from a metal, the cover is opaque. Except for the parts totally surrounded by a recess 20, respectively by a slot 14, the cover 1 is designed as one piece as a whole.
    [0076] As is evident from figure 2, on the back side 11 of the cover 1 a support layer 4 is placed. This support layer 4 extends all over the back side 11 of the cover 1 and, especially, also through the regions of the slots 14 and recesses 20. The support layer 4 is especially used to support, respectively retain, parts of the cover 1 that are completely surrounded by a slot 14 or a recess 20. In the case of elevation 12 with the graphic element 2 in the in the form of an A, this refers here to the island-shaped region 23, and in the case of elevation 12 with the graphic element 2 in the form of a C this refers to the region arranged entirely within the slot 14 and, therefore, especially the entire upper surface 120. The presence of a backing layer 4 also prevents
    22/29 particles of dirt and / or moisture can get inside the display element.
    [0077] In the present execution example, the support layer 4 is produced from a synthetic material injected into the rear side 11 of the cover 1. This synthetic material is specially designed as translucent.
    [0078] On the rear side of the cover 1, a lighting means 3 is provided, which is arranged in such a way that the radiated light illuminates both the slots 14 and the recesses 20. For this purpose, various lighting means 3 can be provided, such as , for example, one for each elevation 12, or the lighting element can be arranged in such a way that all slots 14 and recesses 20 are illuminable. In this way, the light radiated by the lighting medium 3 can pass out through the slits 14 and the recesses 20. Because of this, the graphic elements 2 can be well recognized especially in the dark and, in addition, due to the slits 14, they respectively they are surrounded at least partially by the radiated light. Since the slots 14 are respectively arranged below the graphic element 2, respectively of the recess 20, then the graphic elements 2 appear to the observer as being raised or even floating in relation to the visible side 10 of that part of the covering 1 that involves the elevations 12 In this way, the display element attracts the attention of the observer.
    [0079] For the production of the illuminable display element, in a first stage, for example, a strip-shaped material provided for the cover 1 can be taken to a correspondingly designed shape and in this it can be injected from behind with a material synthetic under pressure. In this process it is possible to apply especially a force so high that the strip-shaped material is deformed due to pressure and the elevations 12 are formed.
    23/29
    The shapes of the elevations 12 are already given in the form used. The synthetic material then forms the support layer 11. Subsequently, the slits 14 and recesses 20 are formed by means of a laser, for example. However, it would also be possible to first configure the slots 14 and recesses 20 by means of stamping, for example, and then to shape the elevations 12 by means of a die and punch, for example, and then to place the support layer. . In that case, the parts of the cover 1 that are completely surrounded by a recess 20, respectively by a slot 14, would naturally have to be retained in place by suitable means, after the configuration of the slits 14, respectively of the recesses 20 and until the placement of the support layer 4.
    [0080] The form of execution shown in figures 5 and 6 differs from that shown in figures 1 and 2, especially in the fact that the graphic elements 2 are configured not by means of recesses 20, but by means of a layer 22 applied to the upper surfaces 120 of the elevations 12. Preferably, the layer 22 is produced from a different material than that of the cover 1. The layer 22 may have, in particular, a surface structure and / or color different from that of the visible side 10 of the cover 1. The layer 22 can be incorporated or printed within the visual range 10 of the cover 1 by means of a glue or an adhesive, for example. In the present embodiment, unlike the embodiment shown in figures 1 and 2, the display element does not have any support layer.
    [0081] A third embodiment according to the invention of an illuminable display element is shown in figures 7 and 8. In this case, the elevations 12 are respectively configured in such a way that, due to their shapes, they respectively form a graphic element 2. In this case, graphic elements 2 are res
    24/29 respectively formed by the shape of the upper flat surfaces 120 of the elevations 2. Below these upper surfaces 120, respectively below the graphic elements 2, also in this form of execution, slits 14 are provided in the lateral surfaces 121 of the elevations 12, which surround the graphics 2 partially or even completely. The elevation 12, shown on the left side of figure 7, which forms the letter A, presents, in the region of the region 23 in the shape of an island of graphic element 2, an internal surface 122 that extends, in a surrounding manner, from the upper surface 120 to low. Within the inner surface 122, other slits 14 are provided. [0082] As is evident from figure 8, in the present example of execution, on the rear side 11 of the roof 1 a support layer 4 is installed which, in the regions of the elevations 12 , grasp the slits 14 so that the support layer 4 with its upper side is aligned with the visible side 10 bordering the cover 1.
    [0083] Between the rear side 11 of the cover 1 and the support layer 4, a sheet 5 can be provided, as shown in figure 9. The sheet 5, which is substantially thinner than the support layer 4 and the cover 1, precisely grips the slots 14 until it with its upper side is aligned with the visible side 10 of the cover 1.
    [0084] In the case of lighting medium 3, it is preferably a light-emitting diode 5. However, it is also conceivable to use a luminescent sheet, especially an electroluminescent sheet or an OLED, or a lamp incandescent. If a luminescent sheet is used, it can be provided as a sheet 5 between the cover 1 and the support layer 4 or alternatively it can be placed on the back side in the support layer 4.
    [0085] As is the case in the forms of execution shown in figures 1 to 9, the lighting medium 3 can be arranged directly
    25/29 in the elevation regions 12 from the rear side in relation to the cover 1. However, execution forms are also possible in which, as shown in figures 10 and 11, the lighting medium 3 is arranged externally to the elevation regions 12. The light radiated by the lighting medium 3 cannot, then, go directly from the lighting medium 3 to the slots 14, respectively to the recesses 20, if these are present. However, in order for the light to reach the slits 14, respectively the recesses 20, the support layer 4 is then configured as a light conductor, within which the light radiated by the lighting means 3 is correspondingly conducted. For this purpose, reflective elements can be provided in or adjacent to the support layer 4 in such a way that the light conducted by the lighting means 3 for the slots 14, respectively for the recesses 20, changes its direction at least once. In this embodiment, it is particularly possible for the display element to have only a single lighting means 2, which is designed to illuminate the slots 14, respectively the recesses 20, of a series of elevations. Of course, also in this embodiment, a sheet 5 can be arranged between the cover 1 and the support layer 4 (see figure 11). Advantageously, the lighting means 3 is embedded in the support layer 4, respectively molded by it. [0086] The support layer 4 and / or the leaf 5 can be designed as a diffuser for the dispersion of the light that passes through the slits 14, respectively of the recesses 20.
    [0087] As in the case of the display element of the embodiment shown in figure 6, the display element shown in figure 12 does not have on the back side of cover 1 neither a support layer nor a leaf. Unlike the form of execution shown in figure 6, in this case the graphic element is formed by the shape of the elevation 12, that is, the shape of the upper layer 120 corres
    26/29 point precisely to that of the graphic element. A display element designed in this way can be produced in a particularly simple way.
    [0088] In the embodiment shown in figure 12, the slits 14 are arranged in an upper region of the elevation 12 close to the upper surface 120. The embodiment shown in figure 13 differs from that in figure 12 in the fact that the slits 14 they are arranged in a lower region of the elevation 12 in the transition region from the lateral surface 121 to the part of the cover 1 that is projected in a flat shape and that surrounds the elevation 12.
    [0089] In the form of execution shown in figure 14, the slits 14 are even arranged outside the elevation 12. The elevation 12, which, due to its shape, forms the graphic element, is here surrounded by cracks at the edges 14.
    [0090] In the form of execution shown in figure 15, directly bordering the elevation 12 on the roof, a survey 17 is set up that surrounds the elevation 12 and that, together with the lateral surface 121 of the elevation 12 forms a surrounding channel 16. Observing in cross-section, therefore, the roof 1 is configured in a wavy or S shape in the region directly bordering the elevation 12. In a lower region of the elevation 12, within the channel 16, the roof 1 has slits 14 that are arranged in such a way that the light that is radiated by the lighting means 3, when passing perpendicularly through the slits 14, falls on the side surface 121 of the elevation 12. Due to this, a particularly attractive visual effect is obtained.
    [0091] In the embodiment shown in figure 6, a channel 16 that at least partially surrounds the elevation 12 is formed due to the fact that the lateral surface 121 extends even below the plane of the cover part 1 that surrounds the elevation 12. Also
    27/29 here, the slits 14 are arranged in the region of the channel 16 in the cover 1 in such a way that the light that passes in a perpendicular direction through the slits 14 falls on the side surface 121. Due to this, the elevation 12 can be radiated laterally by the light from the lighting medium 3.
    [0092] In the embodiment shown in figure 17, the slits 14 are arranged in the transition region of the lateral surface 121 to the part of the cover 1 that surrounds the elevation 12. Here, a relief structure 21, which is configured on the surface elevation 120 of elevation 12, forms the graphic element.
    [0093] The forms of execution shown in figures 18 to 20 differ from the forms of execution shown in figures 1 to 17 in that the graphic elements are arranged, respectively, not within an elevation, but within a recess. 13 of the cover 1. In the forms of execution of figures 18 to 20, the recess 13 is respectively configured in such a way that, due to its shape, it forms a graphic element. Thus, in all three embodiments, the recess 13 has, respectively, a lower surface 130, whose visible side, respectively upper side, is, respectively, in the form of a graphic element. From the lower surface 130, configured flat, a lateral surface 131, respectively surrounding, extends upwards. In that case, the side surface 131 slightly extends upwards.
    [0094] In the embodiment shown in figure 18, the slits 14 are arranged in a lower region of the lateral surface 131 close to the lower surface 130.
    [0095] In the case of the display element shown in figure 19, the slots 14 are located externally to the recess 13, in the part of the cover 1 that extends bordering the recess 13 along the horizontal direction. In addition, other slots 14 are configured in the region
    28/29 transition from the side surface 131 to the part of the cover 1 that surrounds the recess 13.
    [0096] In the embodiment shown in figure 20, the side surface 131 extends upwards beyond the part of the cover 1 that surrounds the recess 13. As a result, a survey 17 forms around the edges of the recess 13 and within which the slots 14 are arranged.
    [0097] Of course, the present invention is not limited to the present embodiments and a multitude of variations is possible. In particular, it is also possible to combine the different characteristics of the forms of execution set out above. In this sense, of course, also in the case of the display elements shown in figures 18 to 20, in which the graphic element is respectively arranged within a recess, it is also possible to place a support layer and / or a sheet on the rear side respectively. of the roof 1. In all the execution examples, respectively for each elevation, respectively recess, it is possible to predict only a single crack, which surrounds the graphic element at least partially or completely, or it is possible to predict more cracks that surround, together , the graphic element at least partially or completely. Of course, within the recesses 13, reliefs or structures may also be provided in relief, which form the graphic element. A multitude of other variants and combinations are conceivable.
