DESCRIPTION

Display panel, method for indicating the price, as well as display panel arranged in a motor vehicle

The invention relates first of all to an independently operable display panel according to the features of the preamble of claim 1. The invention further relates to an assembly comprising a motor vehicle and a display panel according to the features of the preamble of claim 1. characteristics of the preamble of claim 11. Furthermore, the invention relates to a method for indicating the price of a plurality of motor vehicles according to the characteristics of the preamble of claim 13.

Display panels of the type in question are already known. In relation to the state of the art, reference is made, for example, to document DE 10 2013 106821 A1 or also later to document EP 1729 273 A1. The display panel can be arranged inside a motor vehicle, for example, according to Figure 1 of the mentioned EP document. The panel is most preferably arranged in the hole of a ventilation slot. For this purpose, the display panel can also have an insertion projection, as is also known from DE 20 2010 008288 U1. The insertion projection can otherwise be configured in the same plane as the display panel or can be developed in cross section (slightly) at an angle to it.

In this sense, it is also known to manufacture the support part from aluminum or an aluminum composite material, preferably with a plastic coating facing the information element as an outer layer. The support part can also be configured as a plastic panel part specially made of polycarbonate or acrylic and also carbon. The display panel or support part preferably has a side length of up to 400 cm, for example with a rectangular plan.

Such a display panel is in principle suitable for attachment to an adhesive film, as is known, for example, from EP 0833 747 B1, possibly also in the form of an adhesive bag, such as that known from document EP 0930 597 B1.

From document WO 2010/043759 A1 a display panel is known in which a plastic sheet receiving element is hooked to the support piece as a plate rigid to bending. The receiving element forms bags. An elastic screen in the form of electronic paper is inserted into one of the bags. The wiring is configured between the plate-shaped support piece and the bag. From US 6,307,919 B1, the chemical or press-fit attachment of a screen to the front side of the support part is also known. Document EP 0 689 180 A1 discloses an electronic display as such provided with a front cover.

A display panel for placement in a motor vehicle is known from GB 2483258 A. The exhibition panel has a cavity in which a digital photographic element is arranged.

From DE 195 43 643 A1 a display panel is known on which an information sheet can be mounted, the display panel as a whole being able to be attached to a sun visor of a motor vehicle.

A display panel according to the preamble of claim 1 is known from document GB 2249854 A.

An electronic display for mounting on a shelf in a sales store is also known from document US 2010/0031548 A1. The screen is housed in a box-like receptacle that is covered by a lid piece. The screen is fixed inside the receptacle.

Starting from the stated state of the art, the object of the invention is to advantageously configure a display panel of the indicated type. It is also intended to provide an assembly comprising a motor vehicle and such a display panel, as well as a method for indicating the price of a plurality of motor vehicles by using such a display panel.

This task is solved first of all with the object of claim 1.

The wirelessly controllable display is, in particular, a display similar to a known electronic paper. Here, texts or images are preferably displayed permanently without the need for a compensating voltage. However, the display indication can be changed at a later time. With the arrangement of such a screen, the display panel has a display area that can be modified wirelessly. Where appropriate, other non-electronic indications can also be used, such as in particular information elements in the form of sheets of paper and/or, for example, in the form of a print on the carrier part. In this way, a price indication, for example, can be changed without much effort on the display panel.

Since the support part has a window-like opening and the screen is visible through or in the opening, the screen is integrated into the support part.

Several screens arranged independently of each other within or on the display panel may also be provided. With respect to a control system, these displays can also be controlled in an interrelated manner. However, it is preferable that each of them forms a closed autonomous unit that, for example, can also be replaced independently.

The display panel may also present various information elements which may also be separately fastened at various points in the ways described herein.

A display can preferably be controlled via WLAN, Bluetooth or also infrared. Through this wireless connection, the indication can be modified remotely without it being necessary to access the display panel itself.

This possibility offers advantages, for example, when such a display panel is used in motor vehicles to be sold, since here access to the display panel is inconvenient or complicated in the case of closed motor vehicles.

Thus a constantly updated display can advantageously be achieved on the display panel. This update can be carried out by a responsible person by means of data entry, for example via a computer, or alternatively also by using, for example, a smartphone and a corresponding app. Another technical possibility is that the information element has a code, in particular a barcode, which is detected by a scanner, and a preferably direct connection is then created on the basis of this barcode and thanks to direct assignment. between the aforementioned scanner and the screen (using radio technology), so that this information or this price can be transmitted immediately to the screen, if applicable, through a third memory in which the corresponding information is stored, especially a corresponding price.

The display or a control unit assigned to the display preferably has a unique identification for specific control and programming of the display.

In addition to or even instead of the exemplary price information, additional information about the product may also appear on the screen.

The display may be provided with other functional technical elements such as, for example, a battery and/or a radio module and/or a control unit. The functional elements and the display can be provided in a common housing, the display element thus designed as a whole can be assigned to a front side of the support part.

Furthermore, the functional elements may also be provided, if applicable, in a housing part or in a section of the housing part that is separated from the display.

The screen and the functional elements, if necessary separately, are fixed directly to the support part. There is a separable union. A screen is visible, especially, on the front side of the display panel, that is, on the visible side to which the user looks to obtain the information to be provided. The screen can be integrated into the front side of the display panel only with respect to its surface and can be inserted into the opening from the rear of the display panel.

It is especially preferable to arrange an outer display surface of the screen approximately in the same plane as the front side of the support part.

One or more ventilation holes can also be configured in the support part assigned to an area in which the display is arranged or is to be arranged, in order to thus counteract overheating of the display device, especially if the display panel It is arranged in a motor vehicle, for example, behind a windshield. The screen can be arranged on the rear side of the support part through the opening visible from the front side. The screen is visible through or in the opening.

With regard to the fixation especially of the screen, but also preferably of the functional parts, a push-in or snap-in fixation is achieved.

A holding element for the screen is arranged on a rear side of the support part outside the opening. In this way, the fastening element is hidden from direct recognition by a user viewing the front side of the support part or the display panel as a whole. However, since such a display panel can also be freely positioned within a room, if a user views the support part or the display panel in this regard from the rear side, he can naturally, if necessary, recognize the fastening element.

The screen is supported interchangeably on the support element. The support element itself is fixedly connected to the support part as a whole so that it can only be lifted by destruction. A separable connection is provided between the screen, possibly a rear extension of the screen, and the holding element.

In another preferred embodiment, it is provided that on the display panel, on the front side of the support element, a first layer of film is fixed, preferably as part of a receiving bag for an information element, and that the first layer of sheet has a notch that overlaps the opening. This film layer can serve to fix the holding device for the information element, i.e. especially the bag as a whole, on the carrier part. The film layer can, for example, be glued to the corresponding front side of the support part. Since the aforementioned recess is preferably provided in this film layer superimposed on the opening, the screen (in relation to this film layer) is nevertheless directly exposed with respect to its visible surface. However, it is further preferable to apply to the front side of the support element a second film layer covering the first film layer and preferably also extending beyond it, and to configure the second film layer to cover the screen. Consequently, the screen is, in the state of use, covered and protected by the second layer of film.

A fixed film layer can also be placed on the front side of the support part, possibly also as a single film layer, this fixed film layer being able to cover the screen. Such a fixation can be achieved especially by adhesion.

It can further be provided that the firmly fixed film layer is transformed into an area that is not firmly attached to the support part and that can be distanced from the support part, for example by bending outwards. Thus, in this area between the support part and the otherwise firmly attached film layer, an information element can be accommodated, which, in the state of use, is located between the non-fixed area of the film layer and the film part. medium.

The invention further relates to a method for indicating the price of a plurality of motor vehicles.

Until now, for the indication of the price of motor vehicles, the possibility of providing them with display panels is known, with information elements such as, in particular, printed sheets of paper, being arranged on the display panels. The information elements contain, in particular, information about the motor vehicle, but also information about a sales price and, where applicable, information about a financing offer.

Starting from the known state of the art, the invention sets out the objective of providing an advantageous method.

This task is solved with the object of claim 13, a screen forming part of a display panel located inside a motor vehicle according to one of claims 1 to 10.

By means of the wirelessly controllable screen, which is preferably in the form of an electronic paper, a modification of the screen, for example a change in the price of the vehicle, can be carried out remotely, while maintaining other information about the specially marked vehicle through information elements that cannot be modified by radio. Non-variable information elements are, for example, printed sheets of paper and/or printed areas of a support part of the display panel.

Information elements of this type can also preferably be film elements that are, for example, printed and have an adhesive film for direct adhesion to the carrier part. Self-adhesive bags, for example film bags with an adhesive layer, can also be provided for receiving, for example, sheets of paper for adhesion to the carrier part.

In particular, a valid display indication for a plurality of motor vehicles can be modified in particular via a central input point, preferably via a central computer. Said change can also be made using an external device, such as a smartphone or similar.

Thus, a simple adjustment of the parameters to be displayed during the duration of the marking of the various motor vehicles can be carried out advantageously, making it possible to modify, for example, the purchase price or the financing offers.

A change to the screen display can also be carried out from a control center, so that the corresponding change, for example of a purchase price of a certain model, can be carried out simultaneously on site at several connected points of sale. and without any effort on the part of the employees.

Thus, in the case of a plurality of screens that can be controlled wirelessly and that can be modified by the same control system, it can be provided that at least one of the screens that can be modified by the same control system is arranged outside a Motor vehicle. This additional screen arranged outside the vehicle can be, for example, a wall screen or a screen integrated into a desk pad. This way, for example, an employee who has a desk pad and/or a wall display in view has an overview of current prices or financing conditions. In this regard, several such displays can be provided, for example on a wall display, for example, assigned to different motor vehicles each provided with a display that can be controlled wirelessly. A controllable display on a desktop computer can, for example, provide information on current financing conditions or on the current price of a motor vehicle model.

The display panel with the support piece for both the non-controllable information elements and also for at least one wirelessly controllable display can be configured as an insertable or adjustable element, for example for arrangement behind a windshield or a side window of the motor vehicle, as well as, for example, for snap-fitting to a sun visor. The display panel can also be designed as a tabletop display, floor-standing display or ceiling-hung display, as well as a wall display or in the form of a desk pad.

With respect to the object of claim 11 relating to the assembly comprising a motor vehicle and a display panel arranged in the motor vehicle, the objective is to propose an advantageous arrangement.

This task is solved in the object of claim 11.

From a technical operating point of view, a suitable arrangement of such a display panel can be achieved on the inside of the windshield of a motor vehicle.

Preferably, first remove the parasol from one side and turn it to the side. The display panel can then be positioned on the inside of the windshield so that the sun visor, which has returned to its clamping position, requests an elastically bendable end area of the display panel. Through the sun visor, the elastically bendable end region of the display panel is pressed against the inner surface of the windshield by means of the applied tension. This secures the display panel. The tension, especially the spring tension, preferably results only from the material of the display panel or the plate-like support part and/or from the plate geometry of the support part.

Preferably, the elastically bendable end region is configured as a tongue.

In the uninfluenced state of a angled zone, the end zone can also have a line-like transitional shape, which runs transversely to a longitudinal extension of the display panel. The elastic curvature may be provided in the direction of a reduction.

Preferably, a tongue-like section extends at an obtuse angle with respect to the planar extension of the adjacent support piece. The reduction of the bending area can extend to a parallelism of the bending area with respect to the support part, if necessary even further, whereby an almost negative bending can be achieved in the loaded state.

The reduction of the angled area is given by loading the parasol, which is brought to the holding position and, more preferably, to the position of use, in the angled area.

The invention is explained below in view of the attached drawing which, however, only represents embodiment examples. A part which is only explained with reference to one of the exemplary embodiments and which is not replaced by another part in a later exemplary embodiment due to the special feature highlighted there, is therefore also described in relation to this other embodiment example as a part in any possible case.

A display panel 1 is shown and described, first with reference to Figures 1 and 2, having an approximately rectangular plan with a lateral ratio of 1:1.5 to 1:3 and a longer edge length of 10 to 150 cm. It serves, for example, as a price display panel for a motor vehicle 2.

The display panel 1 has a support piece 3 as a plate rigid to bending. The support part 3 is composed, for example, of an aluminum composite material. Alternatively there may also be a solid part of aluminum, if applicable, a part of carbon or a part of another solid plastic, for example polycarbonate. An information element 5 is arranged on one side of the support piece 3, which in the exemplary embodiments is assigned to a front side 4. It may, for example, be a printed paper.

The support part 3 can be coated with a plastic layer, especially on the front side 4. A polyester coating is preferable in this regard.

The information elements 5 are preferably configured for interchangeable adhesion to the front side 4 of the support part 3.

Thus, an information element 5 in the form of printed paper according to the embodiment of Figures 1 and 2 can be housed in a film bag 6, the film bag 6 being adhered on the front side 4 to the support part 3. The foil bag 6 leaves an insertion slot for the information element 5. However, the insertion slot is more preferably provided, see for example also Figure 3, by a simple lifting of the top sheet, also described further. forward in the form of an adhesive film 7. The information element 5 can also be a printed film which, as a result of adhesion, adheres to the front side 4 of the support part 3. In Figures 1 and 2, these elements self-adhesive information labels are provided with the reference 5'.

Furthermore, an information element 5" can be formed by direct printing of an area of the support part 3, especially its front side 4. Accordingly, such an information element 5" cannot be replaced.

In other embodiments, for example according to the representations in FIGS. 3 and 4, the information elements 5 can be attached, for example, in the form of printed sheets of paper, via an adhesive film 7. An adhesive film 7 as this forms a cover for the information element 5, the cover being fixed to the support piece 3 by adhesion. Since the adhesive film 7 protrudes from the information element 5 on the edge side, it rests directly on the front side 4 of the support part 3 and can be adhered there.

In the embodiments shown in Figures 1 to 4, the display panel 1 has a square or rectangular plan. More preferably an insertion section 8 is formed. With this insertion section 8, the display panel 1 can be kept in place in a motor vehicle 2, for example, by insertion into a ventilation slot (compare figure 12) or, in In any case, by means of an insertion behind the windshield.

The display panel 1 can also be provided for placement in a sun visor of the motor vehicle 2 (compare Figure 11), for example by means of a plug-in connection, such as that known in particular from the cited document DE 10 2013 106 821 A1. at first. Furthermore, the configuration of a display panel 1 for arrangement on the roof of a motor vehicle is also known from the aforementioned patent application. In this case, the display panel 1 has magnetic feet 9 for magnetic adhesion to a metal part, here, for example, to the roof of the motor vehicle (compare Figure 13).

According to the representation in Figure 16, in the area of one end side of the display panel 1 an angled area 25 can be provided that forms a U in cross section. In this case, one of the U-arms 26 is formed by the display panel itself and the other U-arm 27, which is significantly shorter, is configured as an overlapping arm for the sunshade 28. The two U-arms 26 and 27 are joined by a U-shaped web 29. Preferably, this adapts approximately in length to the thickness of the parasol 28.

The display panel 1 is held in the U-shaped space of the sunshade 28 by means of the angled area 25 while partially housing the sunshade 28.

Figure 17 shows an alternative possibility for fastening an exhibition panel 1 by using the sunshade 28. The exhibition panel 1 can be configured according to the representation in Figure 2, corresponding to an insertion section 8 that develops at an angle with respect to support piece 3.

To fix the display panel 1 behind the windshield 30, it is preferable to first separate the sunshade 28 on one side from a holding device not shown and turn it to one side. The display panel 1 is then supported on the inside by the windshield 30 with the information elements oriented correspondingly towards the windshield 30.

As a consequence of the support of the angled area (insertion section 8) of the display panel 1 on the inner side of the windshield 30, a spring effect results with a return of the sunshade 28 to the holding position shown in Figure 17, acting the sunshade 28 in this position especially over the area of the line-like transition formation 30 between the support piece 3 and the angled insert section 8.

Thus, the angled area (insertion section 8) is loaded in such a way that it is reduced with respect to the plate-like support piece 3 (as a consequence of the pivotal movement in the direction of parallelism with respect to the supporting piece. support 3). In this way, the display panel 1 is trapped between the windshield 30 and the sunshade 28.

In addition to the static information elements 5", for example in the form of printed areas of the support part 3, and the interchangeable information elements 5 and 5', the display panel 1 preferably presents another information element 5" in the form of a screen 10 that can be controlled wirelessly.

Preferably, the screen 10 can optionally be arranged on the support piece 3. More preferably, the screen 10 functions as an electronic paper.

The display 10 is also provided with functional elements 11 not shown in more detail, such as, for example, a battery and/or a radio module and/or a control unit. The display 10 and the functional elements 11 can be arranged in a common housing 12.

Other possible solutions provide for housing the screen 10 and the functional elements 11 in separate housings.

The fixation of the screen 10 and/or the functional elements 11 can be achieved by a suitable arrangement of an adhesive surface on the screen 10 or on the functional elements 11, adhesion to the support piece being able to be achieved through the adhesive surface. 3, especially on its front side 4, if applicable also on its rear side 13 (compare the embodiment examples in Figures 1 to 4). The adhesive layer can be, for example, an adhesive strip which, if applicable, is adjustable to be removed from the support part 3 without leaving any residue.

In the case of an arrangement of the display 10 and the functional elements 11 in a common housing 12, this unit is fixed on the front side 4 of the support part 3.

Alternatively, an arrangement of such a unit, possibly also only the screen 10, on the rear side 13 according to the representation in Figure 8 is also possible, in which case a window-like opening 14 through which the screen 10 is visible.

Also alternatively, as schematically represented in Figure 5, the screen 10 can be arranged on the front side 4 and, where appropriate, the functional elements 11 can be arranged on the rear side 13 covering it. An opening 15 in the support piece 3 can serve for the passage of ducts 24 between the functional elements 11 and the screen 10.

In the area in which the screen 10 is or is to be arranged in particular, the support part 3 may have one or more ventilation holes 16, in order to achieve ventilation of the interior space of the motor vehicle, for example , if a display panel 1 configured in this way is arranged behind a windshield, temperatures above 80°C can still be reached with this arrangement.

The fixing of the screen 10, if applicable, together with the functional elements 11, can also be carried out according to the representation in Figure 6 also by means of an adhesive sheet 7, this being able to also serve for fixing information elements 5 on the piece. support 3.

The screen 10 can also be arranged, if appropriate, together with the functional elements 11 in a casing 17 (compare Figure 7). This wrapper 17 is configured for adhesive fixation on the surface of the support part, especially on the front side 4. Preferably, the wrapper 17 is formed as an adhesive film at least facing the surface of the support part.

The envelope 17 can also be configured as general heat protection, in order to ensure correct operation of the screen 10, even in the case of an arrangement of a display panel 1 thus designed or equipped, for example, behind a windshield. of a motor vehicle.

Another solution proposed according to Figures 9 and 10 provides for arranging the screen 10 by insertion or snapping, if applicable, together with the functional elements 11. To do this, the housing 12 or the screen 10 preferably extend along a length that It fundamentally corresponds to the distance between two marginal edges of the support piece 3 that develop parallel to each other. As shown, a comparatively shorter screen 10 can alternatively be provided with extension arms 18 that bridge this distance between the marginal edges that run parallel to each other.

In an exemplary configuration, the extension arms 18, in this case directly the screen 10 or its housing 12, are provided with gripping sections 19 that fit through gaps 20 open at the edges and provided on the side of the edge of the support part 3 and which, in the fixed position, rest at least in sections on the rear side 13 of the support part 3.

As a result of the passage of the extension arms 18 through the gaps 20, a snap fixation is possible. A sliding of the screen 10 thus fixed is counteracted.

Furthermore, where appropriate by using gaps 20 like these, the screen 10 can be fixed to the support piece 3 by means of an elastic band that also extends along the rear side 13.

Furthermore, alternatively, instead of the gaps 20, projections protruding from the respective marginal edge of the support part 3 can also be provided to secure the screen 10 to be fixed against displacement.

Alternatively to the embodiment described above, the screen 10 can also be fixed on a support 32. With respect to a horizontal plane, the support 32 can be configured fundamentally in the shape of a U with a U-shaped web 35 joining the U-arms 33 and 34. The screen 10 is fixed on the outside to the U-shaped web 35.

The U-shaped arms 33 and 34 are configured to interact with marginal edges of the support piece 3 that develop parallel to each other and, for this purpose, have slot-like recesses 36 fundamentally adapted to the material thickness of the support piece. support 3 and directed towards each other. Accordingly, the U-arms 33 and 34 are configured to surround the support piece 3 from behind, locking it.

Furthermore, by means of the support 32 the screen 10 can be separated from the oriented display side of the support part 3. In this case, a gap, if any, results between the U-shaped web 35 and the wide oriented side of the support part 3 can be covered on the underside by a base 37, for example molded. The base 37 can also be used to provide additional support to the support 32 on the surface of the support piece 3.

In addition, anti-slip protection can be provided in this way. Such anti-slip protection can also be achieved, for example, by means of a corresponding surface treatment in the area of the recesses 36.

The marginal edge of the base 37 facing the support part 3 can also be provided, for example, with a self-adhesive layer, alternatively with a double-sided adhesive tape.

Figures 20 and 21 show an alternative embodiment of a support 32. This respectively has a hook-shaped extension 38 assigned to the U-arms 33 and 34 for passage through a dimensionally adapted slot 39 in the support part 3. .

After passing through the slot 39 and moving the support 32 downwards, the extensions 38 surround the support piece 3 from behind, resting on the lower marginal edges of the slots 39.

Here also additional support can be provided on the front side of the support part 3 by means of a base 37.

Preferably, the respective slot 39 is covered in the holding position of the holder 32 by the assigned U-arms 33, 34.

The display 10 can serve, for example, to indicate a price, in addition, for example, a sales price of the motor vehicle 2.

The display indication 10 can be changed wirelessly, for example by using infrared, Bluetooth or WLAN.

This offers the possibility of modifying the display indication from a location remote from the display panel 1, especially from a location outside the motor vehicle, for example via a computer or smartphone of an authorized employee or also through remote activation by a central office.

The modification of the display display of several display panels 1, which can be assigned, for example, to the same vehicle type, and possibly also with the same equipment, can be carried out from a central office 21, so that, for example, a price change for a certain motor vehicle model can also be carried out centrally and simultaneously in several buildings.

The screens 10 can be modified using the same control system.

Furthermore, a screen 10 arranged outside a motor vehicle 2 can also be modified correspondingly by the same control system. Such a screen 10 outside a motor vehicle can, for example, form part of a wall panel 22, a plurality of wirelessly controllable screens 10 may also be provided on the wall panel 22 to display, for example, the prices of different models of existing motor vehicles. Furthermore, the screen 10 may be part of a desktop pad 23.

According to the embodiment examples described above and the state of the art mentioned at the beginning, the wall panel 22 and/or the desk pad 23 can be provided, as display panels 1, with a support piece 3 and other support elements. information 5 to 5m

With respect to Figure 22, the support piece (3) that can house the screen (10) in the opening (14) is shown, so that a visible side (40) of the screen (10) is aligned or approximately aligned. with a visible side (41) of the support piece (3). An alternative embodiment is reproduced in Figures 31 to 33, which is also preferable at the time of application. According to this, the screen fits completely to the rear side of the support part, whereby the front side of the screen is aligned correspondingly with at most one rear side of the support part. An approximate alignment is still assumed when the visible side (40) protrudes from the visible side (41) or when a setback occurs in this sense in the area of up to one half or two thirds of a thickness (d) of the support part (3).

The screen arrangements described below in the direction of alignment can also be provided in any case so that the screen is arranged behind the support part in the manner mentioned.

Here, the term screen 10 preferably refers to the entirety of an actual screen and functional parts such as those described above in relation to the screen. In this sense, the screen 10 may have a reception area 42 in which one or more of the aforementioned functional parts are arranged. The screen 10 and, in this case, preferably the reception area 42 can have on the one hand an opposite or also perimeter overlapping section 43, with which they overlap an outer side 44 of the support piece 3 opposite the visible side 41. A hook or adhesion or otherwise created connection between the support piece 3 and the screen 10 can be achieved in the overlapping section 43.

The adhesion can preferably be provided in a detachable manner, for example, in order to be able to replace a screen 10. For this purpose, for example, a hook connection can be realized, a hook element being configured on one side, for example, in the overlap section. 43, and an eyelet element on the opposite side of the support piece 3.

Furthermore, on the assigned side of the support part 3, i.e. the outer side 44, in any case in the area of the overlap section 43, an adhesive film can be placed, and on the assigned area of the support part 3 such a configuration can be provided in the form of a smooth surface that allows adhesion by means of the adhesive sheet. Correspondingly, the embodiment can also be the reverse, with the adhesive sheet being configured in the overlapping section 43 and the smooth surface being provided by the outer side 44.

As long as a replacement possibility is not provided, a simple adhesion of the screen to the support part can of course be provided.

Figure 23 shows a possibility of interchangeable connection according to the claimed invention between the screen 10 and the support part 3. In this case, a clamping part 45 is attached to the outer side 44 of the adjacent support part 3. to the opening 14. For example, the fastening piece 45 can be glued to the support piece 3. In this sense it is preferable that the screen 10 has one or more molded locking areas 46 with which it engages with the fastening piece 45. Especially, the molded locking areas 46 on the screen 10 may be one, two, three or more rod-like protruding elements preferably distributed around the perimeter of the screen 10.

Two of these elements may also be sufficient, since tilting can already be prevented by a close fit of the clamping part 45 to the assigned area of the screen 10.

Figure 24 shows a sectional plan view of the outer side 44 with the fastening piece 45, the screen 10 having been separated.

Figure 25 shows in a perspective view a more specific possible configuration of the clamping part 45.

With reference to Figure 26, a display panel is shown, an opening 14 being configured in the support piece 3, in which the screen 10 is exposed to the outside.

Furthermore, the support part 3 is covered on its visible side 41 in the region of the opening 14 with a first film layer 47. The film layer 47 can be attached to the support part 3 by adhesion. However, it can also, for example, stick to the support part 3.

This first film layer 47 has its own opening, a recess 48, so that direct access to the screen 10 is nevertheless provided from the visible side of the support part 3 with respect to the first film layer 47. .

Above and below, the term "visible outer side or visible side 41" of the support part 3 refers to the outer side of the support part which in the state of use is oriented towards the user, that is, on which The information element (at least partially superimposed) can also be arranged, where appropriate. In connection with the designation "visible side 41" it is not important whether this side is actually visible during use, but only that it is the side of the support part 3 facing the user in the aforementioned manner.

Referring also to Figure 27 it can be seen that the screen 10 is further covered by a second layer of film 49. Preferably, this second layer of film 49 can be lifted, at least in the area of the screen 10, from the piece of support 3, the same being also provided with respect to the first sheet layer 47.

In this way an information element can be inserted between the second film layer 49 and the first film layer 47, preferably outside the screen 10. The screen 10 is, however, visible through the second film layer 49. which is in any case transparent in the display area 10. However, the display is protected from direct contact and, if applicable, also from dirt by the second film layer 49.

Another feature is that the second film layer 49 can be configured with two layers, at least on the edge side, so that a layer 50 assigned to the support part 3 is configured as an adhesive film layer. Due to the two-layer structure, an overlap results with respect to the first film layer 47, even without the second layer 50 being configured as an adhesive film layer, if the first film layer, assigned to the second layer of film, ends in its surface extension in front of the second film layer 49, as shown in Figure 27. The additional layer 51 of the second film layer 49 is preferably configured continuous and also completely overlaps the layer 50.

With reference to Figure 28, a display panel 1 is shown, which may also have several openings 14. In the exemplary embodiment, two openings 14 are shown, which (with respect to a longitudinal extension of the display panel 1) are arranged one above the other. other.

With reference to figures 29 and 30, another configuration of the display panel 1 is shown, which is characterized in that on the visible side 41 of the support piece 3 a layer of film 52 is placed on at least a part of its firmly attached surface. to the support part 3. The film layer 52 can, for example, be glued or welded to the support part 3 in the aforementioned area. This last option could be suitable if the support part 3 is made of plastic or has a plastic surface.

In the region of the film layer 52 firmly attached to the support part 3, one or more openings 14 are formed, preferably each also provided with a screen 10.

Furthermore, the film layer 52 preferably has an area 53 that is not attached to the support part 3. In the area 53, as can be seen in Figure 30, the film layer 52 is provided flexibly with respect to the side. visible 41 towards a user, so that an information element 5 can be inserted between the sheet layer 52 and the support piece 3. The sheet layer 52 is preferably formed with a rigidity such that it automatically moves back into its position contact when released with the information element 5 inserted or, in any case, remains in the contact position when moved back to said position.

The film layer 52 can be configured as an adhesive film, if applicable also only on the edge side, in any case in the area 53 assigned to the support part 3. However, it can also be configured as an adhesive film, for example, like a polyester sheet, and therefore come into firm contact with the support part 3 only by lightly pressing it with the hand.

In the state of use, the information element 5 is preferably configured smaller on the edge side, so that a marginal area results in which the area 53 of the film layer 52 can rest directly on the outer side of the support piece 3. The sheet layer 52 can also continue into another area 52' which is also firmly attached to the support part 3. Especially, as shown in Figure 30, the area 52' can extend above the area 53 of the foil layer 52. Otherwise, it does not need to be attached to the foil layer 52.

As can be further seen in Figures 29 and 30, the area 53 of the sheet layer 52 is provided so that the free end (in relation to the cross section according to Figure 30) extends in the opposite direction to a lower area of the support piece 3 provided by the angled area 25 in the exemplary embodiment, that is, preferably an insertion area. Thus, during use, gravity alone ensures that the information element 5 cannot fall directly downwards when opening the area 53.

Preferably, although a folding line is also possible, the sheet layer 52 extends directly with its own thickness towards the area 53 without bending, weakening or the like. The transition is given only by the limit of the adhesion or other type of union between the firmly bonded area of the sheet layer 52 and the area 53. With reference to Figure 31, another possible embodiment is represented in accordance with the claimed invention. of a holding part 45', here in a view of the rear side of a supporting part 3. This holding part 45' is arranged on the rear side of the supporting part with a marginal distance r with respect to a marginal edge of the opening 14. Preferably, it is glued to the support piece.

The holding piece 45' can be formed, as in the example of embodiment shown, perimeter in the form of a closed frame. Only one of the arms of the fastening piece 45' can also be made, namely, the arm on which the fastening tab 45 is configured.

In such a case, the screen 10 can be inserted between the retaining tab 54 and the rear side of the support piece 3. Figure 31 shows the screen during the insertion process. Here, the screen 10 preferably fits within the marginal edge of the holding part 45', in particular within the peripheral marginal edge of the holding part 45', directly to a rear side of the supporting part 3.

In this exemplary embodiment and preferably also in all other described exemplary embodiments, the display 10 is configured as a modular overall unit with all necessary functional parts, especially also with an accumulator and a battery for independent power supply.

The fastening tab 54 is preferably configured so that it elastically bends upward, so that no other fastening elements are required. The screen 10 can be easily replaced.

With respect to Figure 32, a cross section is shown through another embodiment of a housing, here referred to as housing 12'. In the shown cross section it can be seen that the housing essentially has a C shape. In the assembled state, the continuous C bracket, which preferably also has a viewing window 55 formed as a through hole, is arranged on the side. front of the support piece. The C-arms 56 and 57 surround the support part 3. Preferably, the combined action is such that a clamping connection results between the housing 12' and the support part 3. The housing 12' can be easily placed from above on the support piece 3 and can be moved vertically to its desired position.

Preferably, on the rear side of the continuous C-arm 58, another frame part 59 is mounted on the inner side facing the support part 3. The screen 10, preferably in the manner of the module already described, is removably housed in said part. The frame part 59 is preferably configured perimeter or, in any case, at least on three or four sides with respect to the module 10, so that the module 10 cannot fall onto the support part 3 even in the assembled state of the casing 12'.

In this case, the support part 3 can be configured in a continuous, uninfluenced manner, i.e. without an opening. With respect to Figure 33, an exploded representation of the housing 12', the frame part 59 and the screen 10 is shown.

In addition to the embodiment of Figures 26 and 27, a configuration is possible in which a second layer 50, which results in relation to the longitudinal marginal edge of the rectangular display panel shown, but also in general, presents as a whole in the overlapping area a window-like recess corresponding to the opening 14 or, in any case, to the visible surface of the screen 10 but configured closed around this gap, so that the adhesive sheet, which preferably forms the second layer of sheet 50, surround it in a closed manner with respect to the opening 14 and also waterproof it correspondingly in the covered state. Therefore, the edges of the film layer 51, formed on the underside by the film layers 50, are configured with different widths when viewed in the width direction of the display panel. On the side on which the opening 14 is configured, a considerably larger width is formed than on the opposite side. However, in the area of the wide frame, a continuous film layer 50 is also provided, so that, when viewed along and from the top of the display panel, a very good appearance results here in the state of use. adhesion between the second layer of film and the support part in the state of use.
