EP3029658B1 - Display board, method for pricing and display board arranged inside an automotive vehicle - Google Patents

Description

The invention initially relates to an independently manageable display board according to the features of the preamble of claim 1. The invention also relates to an arrangement comprising a motor vehicle and a display board according to the features of the preamble of claim 11. The invention also relates to a method for displaying prices for a plurality of Motor vehicles according to the features of the preamble of claim 13.

Display boards of the type in question are known. So the state of the art is about the DE 10 2013 106821 A1 or further on EP 1 729 273 A1 referred. The display panel can within a motor vehicle, for example according to figure 1 the mentioned EP specification. This more preferably in the opening of a ventilation slot. For this purpose, the display board can also have a plug-in projection, as is further illustrated in FIG DE 20 2010 008288 U1 is known. The insertion projection can otherwise be formed at the same level as the display panel or run at a (slightly) angled cross-section thereto.

In this connection it is also known to produce the carrier part from an aluminum or an aluminum composite material, preferably with a plastic coating facing the information element as the outer layer. The carrier part can also be designed as a plastic plate part, in particular made from polycarbonate or acrylic, and also from carbon. The display board or the support part preferably has a side length of up to 400 cm, for example with a rectangular floor plan.

Such a display board is initially favorable for connection with an adhesive film, such as that from the EP 0 833 747 B1 is known, possibly also in the form of an adhesive bag, as from the EP 0 930 597 B1 is known.

From the WO 2010/043759 A1 a display board is known in which a receiving element made of film plastic is attached to the rigid plate-like support part. The receiving element forms pockets. In one of the pockets, an elastic display is inserted as electronic paper. Wirings are formed from the plate-like supporting part to the pocket. Next it is from the US 6,307,919 B1 known to chemically fasten a display on the front side of a carrier part or by means of a press fit. The EP 0 689180 A1 discloses an electronic display as such provided with a front cover.

From the GB 2483258A a display board for mounting in a motor vehicle is known. The display board has a depression in which a digital photo element is arranged.

From the DE 195 43 643 A1 a display board is known in which an information sheet can be held and the display board as a whole can be held on a sun visor of a motor vehicle.

From the GB 2 249 854 A a display board according to the preamble of claim 1 is known.

From the US 2010/0031548 A1 an electronic display unit for attachment to a shelf in a retail store is also known. The display is accommodated in a box-like receptacle which is covered by a lid part. The display is fixed inside the mount.

Proceeding from the prior art presented, the invention is concerned with the task of advantageously designing a display board of the type specified. Also to specify an arrangement comprising a motor vehicle and such a display board, as well as a method for displaying the price of a plurality of motor vehicles using such a display board.

This object is initially achieved with the subject matter of claim 1.

The wirelessly controllable display is in particular a display in the manner of a known e-paper. In this case, texts or images are preferably displayed permanently, without a conservation voltage being required for this. However, what is shown on the display can be changed at a later date. With the arrangement of such a display, the display board has a display area that can be changed wirelessly. Possibly in addition to other, non-electronic displays, such as in particular information elements in the form of sheets of paper and/or, for example, in the form of printing on the carrier part. In this way, a low-effort change, for example a price indication on the display board, can be carried out.

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

Several displays, which are arranged independently of one another in or on the display board, can also be provided. With regard to control, these displays can also be controlled in a coherent manner. However, it is preferred that they each form an independent, self-contained unit that can also be independently exchanged, for example.

The display board can also have several information elements, which can also be held separately several times in the manner described here.

A display can preferably be controlled via WLAN, Bluetooth or infrared. This wireless connection allows the display to be changed remotely without having to access the display board itself.

This offers advantages, for example, when using such a display board in motor vehicles to be sold, since access to the display board is awkward or difficult when the motor vehicle is locked.

In this way, a constantly updated display on the display board can be achieved in an advantageous manner. This can be done by a responsible person by means of input, for example via a computer, alternatively, for example, using a smartphone and a corresponding app. A further technical possibility is that the information element has a code, in particular a barcode, which is detected by a scanner and then, based on this barcode, because of the direct assignment, a connection is preferably created directly between the said scanner and the display - by radio technology so that this information or this price can then be transmitted to the display, if necessary via a third memory in which the associated information, in particular an associated price, is stored.

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

In addition to or instead of exemplary price information, further product information can also be listed on the display.

The display can be provided with additional technical functional elements, such as an accumulator and/or a radio module and/or a control unit. The functional elements and the display can be provided in a common housing, with the display element designed in this way being assigned to a front side of the carrier part overall.

In addition, the functional elements can also be provided in a housing part or housing part section that is separate from the display.

The display and the possibly separate functional elements are attached directly to the carrier part. There is a detachable connection. A display is visible in particular on the front of the display board, ie the visible side which a user looks at to record the information to be conveyed. The display can only be integrated into the front of the display board with regard to its surface and can be used in the breakthrough from the rear of the display board.

In particular, it is preferred that a visible outer surface of the display is arranged approximately at the same level as the front side of the carrier part.

One or more ventilation holes can also be formed in the carrier part, assigned to an area in which the display is arranged or is to be arranged, in order to counteract overheating of the display, especially when the display board is arranged in a motor vehicle, e.g. behind a windshield . The display can be arranged on the back of the carrier part, visible through the opening from the front. The display is visible through or in the opening.

With regard to the definition of the display in particular, but also more preferably the functional parts, a plug-in or slide-in definition is achieved.

A holding element for the display is arranged on a rear side of the carrier part outside of the opening. The mounting element is thus not directly recognizable by a user who is looking at the front of the support part or the display panel as a whole. However, since such a display board can also be set up freely within a room, a user can of course recognize the holding element if he/she looks at the support part or the display board in this sense from the rear.

The display is exchangeably held on the holding element.

The holding element itself is firmly connected to the carrier part as a whole, which can only be removed by destroying it. Between the Display, possibly a rear extension of the display, and the support element is given a detachable connection.

In a further preferred embodiment it is provided that a first film layer is attached to the display board on the front side of the carrier element, preferably as part of a receiving pocket for an information element, and that the first film layer has a recess overlapping the opening. This film layer can be used to attach the holder for the information element, ie in particular the pocket as a whole, to the carrier part. The film layer can, for example, be glued to the relevant front side of the carrier part. Due to the fact that, more preferably, the said recess is provided in this film layer so that it overlaps the opening, the display—in relation to this film layer—is nevertheless directly exposed with regard to its visible surface. However, it is further preferred that a second film layer is applied to the front side of the carrier element, which covers the first film layer and preferably also extends beyond it, and that the second film layer is designed to cover the display. Thus, when in use, the display is nevertheless covered and protected by the second film layer.

A firmly attached foil layer can also be attached to the front side of the carrier part, optionally also as the only foil layer, and the display can be covered by this firmly attached foil layer. Such a fixed attachment can be achieved in particular by gluing.

Furthermore, it can be provided that the firmly attached film layer merges into an area that is not firmly connected to the carrier part and can be distanced from the carrier part by bending out, for example. An information element can thus be accommodated in this area between the carrier part and the otherwise firmly attached film layer, which is then located between the non-permanently attached area of the film layer and the carrier part when in use.

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

In order to mark the price of motor vehicles, it has hitherto been known to provide them with display boards, on which display boards information elements, such as in particular printed sheets of paper, are arranged. The information elements are in particular provided with information on the motor vehicle, but also with information on a sales price and, if applicable, information on a financing offer.

Proceeding from the known state of the art, the invention is concerned with the task of specifying an advantageous method.

This object is achieved with the subject matter of claim 13, wherein a display part of an information board located inside a motor vehicle according to one of claims 1 to 10 is carried out.

Via the wirelessly controllable display, which is preferably in the form of an e-paper, a display change, e.g. a change in the vehicle price, can be carried out remotely, while further information about the marked vehicle is retained, in particular via the information elements that cannot be changed by radio. The information elements that cannot be changed are, for example, printed sheets of paper and/or printed areas of a carrier part of the display board.

Such information elements can also, as is also preferred, be film elements that are printed, for example, and have an adhesive film for direct attachment to the carrier part. Self-adhesive pockets, for example foil pockets with an adhesive layer, can also be provided for holding sheets of paper, for example, for adhesion to the carrier part.

In particular, a display reading that is valid for a plurality of motor vehicles can be changed via a central input point, preferably via a central computer. Such a change can also be made by an external device such as a smartphone or the like.

Advantageously, parameters to be displayed can be advantageously adjusted over the duration of the labeling of the individual motor vehicles, such as the purchase price or financing offers being adjusted.

The display can also be changed from a central location, so that a corresponding change, for example a purchase price of a specific model, can be carried out in a number of connected sales outlets simultaneously and without any effort for the on-site employees.

Thus, in the case of a plurality of wirelessly controllable displays that can be changed by the same control, provision can be made for at least one of the displays that can be changed by the same control to be arranged outside of a motor vehicle. This further display, which is arranged outside of a motor vehicle, can be, for example, a wall display or a display integrated into a desk pad. For example, an employee has an overview of current prices or financing conditions by looking at his desk pad and/or by looking at a wall display. In this respect, several such displays can be provided, for example in a wall display, for example assigned to different motor vehicles, each provided with a wirelessly controllable display. A controllable display in a writing pad can, for example, provide information about current financing conditions or about the current price of a motor vehicle model.

The display board with the carrier part for both non-controllable information elements and for at least one wirelessly controllable display can be used as a plug-in or control element, for example. For arrangement behind a windshield or a Be formed side window of the motor vehicle, further, for example. Also for clamp mounting on a sun visor. The display board can also be designed as a table display, stand display or ceiling hanger, as well as a wall display or in the form of a desk pad.

With regard to the subject matter of claim 11 relating to the arrangement comprising a motor vehicle and a display panel which is arranged in the motor vehicle, the object is to specify an advantageous arrangement.

This object is achieved with the subject matter of claim 11 .

An arrangement of such a display board that is favorable in terms of handling can be achieved on the inside of a motor vehicle windshield.

For this purpose, the sun visor is preferably first detached on one side and swung aside. The display board can then be placed on the inside of the windshield in such a way that an elastically bendable end area of the display board is loaded by the sun visor, which has been brought back into its mounting position. The elastically bendable end portion of the display board is pressed against the inner surface of the windshield by the tension applied by the sun visor. The display board is held like this. The tension, especially spring tension, results preferably solely from the material of the display panel or the plate-like support part and/or the plate geometry of the support part.

The elastically bendable end region is preferably designed like a tongue.

In the unaffected state of a bend, the end region can also have a line-like transition shape running transversely to a longitudinal extension of the display panel. The elastic deflection can be given in the sense of a reduction.

A tongue-like section preferably extends at an obtuse angle to the plane extension of the adjoining carrier part. The reduction in the angling can extend to a parallelism of the angling area to the carrier part, possibly even beyond this, with which a quasi negative angling can be achieved in the loaded state.

The angling is reduced by a load on the angling area of the sun visor brought into the holding position and, more preferably, into the usage position.

Shown and described, first with reference to the Figures 1 and 2 , a display board 1, which has an approximately rectangular plan, with an aspect 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 board for a motor vehicle 2.

The display board 1 has a rigid, plate-like support part 3 . The carrier part 3 consists, for example, of an aluminum composite material. Alternatively, there can also be a solid aluminum part, possibly a carbon part or a part made of some other solid plastic, for example made of polycarbonate.

An information element 5 is arranged on one side of the carrier part 3, assigned to a front side 4 in the exemplary embodiments. It can, for example, be printed paper.

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

The information elements 5 are preferably designed to be attached to the front side 4 of the carrier part 3 so that they can be exchanged.

Thus, an information element 5 in the form of printed paper according to the embodiment in FIGS Figures 1 and 2 be included in a foil pouch 6, which foil pouch 6 is attached to the carrier part 3 on the front side 4. The film pocket 6 leaves an insertion slot for the information element 5. However, the insertion slot is more preferred, see also figure 3 , given by simply lifting the top film, also described below in the form of an adhesive film 7. The information element 5 can also be a printed foil which is arrested according to adhesion on the front side 4 of the carrier part 3. In FIGS. 1 and 2, such self-adhesive information elements are provided with the reference number 5'.

In addition, an information element 5" can be formed by directly printing an area of the carrier part 3, in particular its front side 4. Such an information element 5" is therefore not exchangeable.

In further embodiments, for example according to the illustrations in FIGS Figures 3 and 4 , information elements 5 can be defined, for example in the form of printed sheets of paper, via an adhesive film 7 . Such an adhesive film 7 forms a cover for the information element 5, which cover is attached to the carrier part 3 by adhesion. Due to the fact that the adhesive film 7 protrudes beyond the information element 5 at the edge, it rests directly on the front side 4 of the carrier part 3 and can adhere there.

At the in the Figures 1 to 4 In the illustrated embodiments, the display board 1 has a square to rectangular outline. More preferably, an insertion section 8 is formed. With this plug-in section 8, the display board 1 can be plugged into a motor vehicle 2, for example by plugging it into a ventilation slot (cf. figure 12 ) or at least a plugging behind the windshield.

The display panel 1 can also be provided for arrangement on a sun visor in the motor vehicle 2 (cf. figure 11 ), For example, as a result of a plug-in connection, such as these in particular from the initially cited DE 10 2013 106 821 A1 is known. Furthermore, the design of a display board 1 for arrangement on a motor vehicle roof is also known from the aforementioned patent application. In this case, the display board 1 has magnetic feet 9 for magnetic attachment to a metal part, here for example on the motor vehicle roof (cf. figure 13 ).

According to the illustration in figure 16 For example, an angled portion 25 can be provided in the area of one end side of the display panel 1, which forms a U-shape in cross section. In this case, one leg 26 of the U is formed by the display panel as such and the other leg 27 of the U, which is significantly shorter, is designed as an overlapping leg for the sun visor 28 . The two U-legs 26 and 27 are connected by a U-web 29. The length of this is preferably approximately adapted to the thickness of the sun visor 28 .

The display board 1 is held on the sun visor 28 in the U-space by means of the angled portion 25 while partially accommodating the sun visor 28 .

figure 17 shows an alternative mounting option for a display board 1 using the sun visor 28. The display board 1 can be mounted as shown in figure 2 be designed correspondingly with an insertion section 8 running at an angle in relation to the carrier part 3.

In order to fix the display board 1 behind the windshield 30, the sun visor 28 is first, as further preferred, detached on one side from a holder (not shown) and swung aside. The display panel 1 is then leaned against the windshield 30 on the inside, with the information elements correspondingly facing the windshield 30 .

As a result of the support of the bend (insertion section 8) of the display board 1 on the inside of the windshield 30, there is a spring effect with the sun visor 28 being displaced back into the in figure 17 shown mounting position, in which position the sun visor 28 acts in particular on the area of the linear transitional shaping 30 between the carrier part 3 and the angled plug-in section 8 .

The bend (insertion section 8) is thus stressed in such a way that it is reduced compared to the plate-like carrier part 3 (due to pivot displacement in Direction of parallelism to the carrier part 3). The display board 1 is clamped between the windshield 30 and the sun visor 28 .

In addition to the static information elements 5", for example in the form of printed areas of the carrier part 3 and the exchangeable information elements 5 and 5', the display board 1 preferably has another information element 5‴ in the form of a wirelessly controllable display 10.

The display 10 can preferably be optionally arranged on the carrier part 3 . The display 10 more preferably works in the manner of an e-paper.

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

Other possible solutions envisage accommodating the display 10 and the functional elements 11 in separate housings.

The display 10 and/or the functional elements 11 can be fixed in place by appropriately arranging an adhesive surface on the display 10 or on the functional elements 11 on the back 13, is accessible (see. Examples in the Figures 1 to 4 ). The adhesive layer can, for example, be an adhesive strip, which is optionally adjusted for removal from the carrier part 3 without leaving any residue.

With an arrangement of display 10 and functional elements 11 in a common housing 12, this unit is attached to the front side 4 of the carrier part 3.

Alternatively, such a unit, but possibly only the display 10, can also be arranged on the back 13 as shown in FIG figure 8 possible, where in In this case, a window-like opening 14 is provided in the carrier part 3, through which the display 10 is visible.

Further alternatively, as schematically in figure 5 shown, the display 10 can be arranged on the front side 4 and the functional elements 11 can be arranged on the back side 13, possibly overlapping it. An opening 15 in the carrier part 3 can be used to lead through lines 24 between the functional elements 11 and the display 10 .

In the area in which the display 10 in particular is or is to be arranged, the carrier part 3 can have one or more ventilation holes 16, for example when a display board 1 designed in this way is arranged behind a windshield, in which arrangement temperatures of over 80 ° C can be achieved to achieve ventilation to the interior of the vehicle.

The definition of the display 10, possibly together with the functional elements 11, can also be carried out according to the illustration in figure 6 can also be achieved via an adhesive film 7, as this can also be used to fix information elements 5 on the carrier part 3.

The display 10 can also be arranged in a casing 17 together with the functional elements 11 (cf. figure 7 ). This covering 17 is designed for adhesive attachment to the partial carrier surface, in particular on the front side 4. The covering 17 is preferably formed at least facing the partial carrier surface in the manner of an adhesive film.

The casing 17 can also be designed to protect against heat overall, in order to ensure proper operation of the display 10 even when a display board 1 designed or equipped in this way is arranged, for example behind a windshield of a motor vehicle.

Another proposed solution according to the Figures 9 and 10 provides a slide-in or snap-in arrangement of the display 10, possibly together with the functional elements 11. For this purpose, the housing 12 or the display 10 preferably extends over a length which essentially corresponds to the distance between two peripheral edges of the carrier part 3 running parallel to one another. As shown, a comparatively shorter display 10 can alternatively be provided with cantilevers 18 bridging this distance between the edges running parallel to one another.

In an exemplary embodiment, the brackets 18, possibly directly the display 10 or its housing 12, are provided with gripping sections 19, which grip through open-edged openings 20 provided on the edge of the carrier part 3 and, in the fixed position, at least partially on the back 13 of the Support carrier part 3.

As a result of the penetration of the cantilevers 18 through the openings 20, a snap-in fixing is made possible. A sliding of the display 10 fixed in this way is counteracted.

If necessary, the display 10 can also be attached to the carrier part 3 via an elastic band that also extends over the rear side 13 using such openings 20 .

As a further alternative, instead of the breakouts 20, projections can also be provided which protrude beyond the respective edge of the carrier part 3, in order to secure the display 10 to be fixed against displacement.

As an alternative to the configuration described above, the display 10 can also be attached to a holder 32 . The holder 32 is essentially U-shaped in relation to a floor plan, with a U-web 35 connecting the U-legs 33 and 34. The display 10 is attached to the U-web 35 on the outside.

The U-legs 33 and 34 are designed to interact with mutually parallel peripheral edges of the carrier part 3 and for this purpose have groove-like recesses 36 which are essentially adapted to the material thickness of the carrier part 3 and are directed towards one another. The U-legs 33 and 34 are designed to engage behind the carrier part 3 in a latching manner.

In addition, the display 10 can be spaced from the facing presentation side of the carrier part 3 by the holder 32 . Any gap that may result between the U-web 35 and the broad side of the carrier part 3 facing it can be covered on the underside by a bottom 37 that is molded on, for example. Furthermore, the holder 32 can be further supported on the surface of the carrier part 3 via the base 37 .

In addition, this can be used to prevent slipping. Such an anti-slip device can also be achieved, for example, by appropriate surface treatment in the area of the recesses 36 .

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

The Figures 20 and 21 show an alternative embodiment of a holder 32. This has associated with the U-legs 33 and 34 in each case a hook-shaped extension 38 for reaching through a dimensionally adapted slot 39 in the carrier part 3.

After passing through the slot 39 and a downward displacement of the holder 32, the extensions 38 engage behind the carrier part 3 with support on the lower edges of the slots 39.

Here too, further support on the front side of the carrier part 3 can be provided by a floor 37 .

The respective slot 39 is preferably covered by the associated U-leg 33, 34 when the holder 32 is in the holding position.

The display 10 can be used, for example, to display a price, further, for example, a selling price of the motor vehicle 2.

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

This offers the possibility of changing the display from a location remote from the display board 1, in particular from a location outside the motor vehicle, for example via a computer or a smartphone of an authorized employee or by remote triggering by a central location.

The change in the display of several display boards 1, which can, for example, each be assigned to the same type of vehicle, possibly with the same equipment, can be made from a central location 21, so that, for example, a price change for a specific motor vehicle model can also be made centrally in can be carried out in several houses at the same time.

The displays 10 can be changed by the same control.

Furthermore, a display 10 that is arranged outside of a motor vehicle 2 can also be correspondingly changed by the same control. Such a display 10 outside a motor vehicle can, for example, be part of a wall panel 22, on which wall panel 22 there can also be a plurality of wirelessly controllable displays 10 for displaying, for example, the prices of various existing motor vehicle models. The display 10 can also be part of a desk pad 23 .

Blackboard 22 and/or desk pad 23 can be used as display boards in accordance with the exemplary embodiments described above and the prior art cited at the outset 1 be provided with a carrier part 3 and other information elements 5 to 5 ‴.

In reference to figure 22 shows that the carrier part (3) can accommodate the display (10) in the opening (14) in such a way that a visible side (40) of the display (10) is flush or almost flush with a visible side (41) of the carrier part (3). . An alternative embodiment, which is also preferred at the time of filing, is in Figures 31 to 33 played back. After that, the display as a whole rests against the back of the carrier part and the front side of the display is aligned with a back side of the carrier part. Approximate alignment is still assumed if the visible side (40) protrudes beyond the visible side (41) or is backwards in the range of up to one half or two thirds of a thickness (d) of the carrier part (3).

The arrangements of the display described below in the sense of an alignment can also be provided in any case in such a way that the display is arranged behind the carrier part in the manner discussed.

The term display 10 here preferably refers to the entirety of an actual display and of functional parts, as they are named above for the display. In this respect, the display 10 can have a receiving area 42 in which one or more of the functional parts mentioned are arranged. The display 10 and here preferably the receiving area 42 can have an overlapping section 43 on one side, opposite or also circumferentially, with which they overlap over an outer side 44 of the carrier part 3 opposite the visible side 41 . In the overlapping section 43, a latching or gluing or connection produced in some other way between the carrier part 3 and the display 10 can be achieved.

The attachment can preferably be provided in a detachable manner in order to be able to exchange a display 10, for example. For this purpose, for example, a Velcro connection can be realized by a hook element on one side, such as the overlapping section 43, and on the opposite side of the carrier part 3 an eyelet element.

Furthermore, an adhesive film can be attached to the assigned side of the carrier part 3, i.e. the outer side 44, at least in the area of the overlapping section 43 and in the assigned area of the carrier part 3 such a design in the form of a smooth surface, which enables adhesion by means of the adhesive film . Correspondingly, the design can also be reversed, that is, the adhesive film is formed on the overlapping section 43 and the smooth area is provided by the outside 44 .

If interchangeability is not intended, the display can of course simply be glued to the carrier part.

A possibility of the exchangeable connection according to the claimed invention between the display 10 and the carrier part 3 is in figure 23 shown. In this case, a holding part 45 is attached to the outside 44 of the carrier part 3, adjacent to the opening 14. For example, the mounting part 45 can be glued to the carrier part 3 . In this context, it is preferred that the display 10 has one or more latching formations 46 with which it is latched to the mounting part 45 . In particular, one, two, three or more, preferably distributed over the circumference of the display 10 , projecting, rod-like elements can be used as latching formations 46 on the display 10 .

Two such elements can also be sufficient since tilting can already be prevented by a tight fit of the holding part part 45 on the assigned area of the display 10 .

figure 24 shows a top view, in section, of the outer side 44 with the mounting part 45, the display 10 having been removed.

figure 25 shows a perspective view of a possible more specific embodiment of the mounting part 45.

In reference to figure 26 a display board is shown, in which an opening 14 is formed in the carrier part 3, in which the display 10 is exposed to the outside.

Furthermore, the carrier part 3 is covered with a first film layer 47 on its visible side 41 in the area of the opening 14 . The foil layer 47 can be connected to the carrier part 3 by adhesive bonding. However, it can also be glued to the carrier part 3, for example.

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

Above and below, the term "visible outside or visible side 41" of the carrier part 3 refers to the outside of the carrier part that faces the viewer when in use, on which the information element is also arranged - at least partially overlapping. For the designation "visible side 41" it is not important whether this side is actually visible during use, but only that it is that side of the carrier part 3 which faces the user in the manner mentioned.

With further reference to figure 27 it can be seen that the display 10 is further covered by a second film layer 49 . This second film layer 49 is preferably provided, at least in the area of the display 10, so that it can be lifted off the carrier part 3 and also with respect to the first film layer 47.

An information element can thus be inserted between the second film layer 49 and the first film layer 47, preferably outside of the display 10. The display 10 is nevertheless visible through the second film layer 49, which is in any case transparent in the area of the display 10. However, it is before direct contact and possibly also contamination by the second film layer 49 protected.

In further detail, the second film layer 49 can be formed in two layers, at least at the edge, in such a way that a layer 50 assigned to the carrier part 3 is designed as an adhesive film layer. Due to the two-layer structure, there is an overlap with respect to the first film layer 47 even without the fact that the second layer 50 is in the form of an adhesive film layer, if this, as in figure 27 is shown, associated with the second film layer 49 ends in front of this in surface extension. The further layer 51 of the second film layer 49 is preferably continuous and also completely overlaps layer 50.

In reference to figure 28 it is shown that a display board 1 can also have several openings 14 . In the exemplary embodiment, two openings 14 are shown, which - are arranged one above the other - based on a longitudinal extension of the display board 1 .

Related to the Figures 29 and 30 a further embodiment of the display board 1 is shown, which is distinguished by the fact that on the visible side 41 of the carrier part 3 a film layer 52 is attached to the carrier part 3, at least over part of its surface. The film layer 52 can, for example, be glued or welded to the carrier part 3 in the region mentioned. The latter could be appropriate if the carrier part 3 consists of plastic or has a plastic surface.

One or more openings 14 are formed in the area of the film layer 52 which is firmly connected to the carrier part 3 and which are also preferably provided with a display 10 in each case.

Furthermore, the foil layer 52 preferably has a region 53 which is not attached to the carrier part 3 . The film layer 52 is in the area 53, as shown in FIG figure 30 seen, provided bent away with respect to the visible side 41 to an observer, so that an information element 5 can be inserted between the foil layer 52 and the carrier part 3 . The film layer 52 is preferably formed with such rigidity that it automatically moves back into its contact position when it is released when the information element 5 is inserted or in any case remains in the contact position when it is shifted back there.

In any case, the film layer 52 can be configured as an adhesive film in the area 53 assigned to the carrier part 3, optionally also only at the edge. However, it can also be designed as a non-adhesive film, ie as a polyester film, for example, and accordingly only come into firm contact with the carrier part 3 by painting it by hand.

When in use, the information element 5 is preferably designed to be smaller at the edge, resulting in an edge region in which the region 53 of the film layer 52 can rest directly on the outside of the carrier part 3 . The film layer 52 can also continue into a further area 52 ′, which is also firmly connected to the carrier part 3 . The area 52' can in particular, as in figure 30 shown, extend above the region 53 of the foil layer 52 . Moreover, it does not need to be connected to the foil layer 52 .

How further from the Figures 29 and 30 visible, the area 53 of the film layer 52 is provided so that the free end - based on the cross section according to figure 30 - extends opposite to a given by the bend 25 in the embodiment lower portion of the support part 3, so preferably an insertion area. Thus, during use, gravity alone ensures that the information element 5 cannot fall out immediately when the area 53 is opened.

Although a fold line is also possible, the film layer 52 preferably extends directly into the area 53 with the same thickness without a fold, weakening or the like other attachment between the firmly attached area of the film layer 52 and the area 53 given.

In reference to figure 31 Another possible embodiment according to the claimed invention of a mounting part 45' is shown, here in a view of the rear of a carrier part 3. This mounting part 45' is arranged at a distance r from a peripheral edge of the opening 14 on the rear of the carrier part. It is preferably glued to the carrier part.

As in the exemplary embodiment shown, the holding part 45' can be formed in a closed, circumferential manner in the manner of a frame. It is also possible for only one of the legs of the holding part 45', namely the leg on which the holding tongue 45 is formed, to be realized.

The display 10 can then be inserted between the retaining tongue 54 and the rear side of the carrier part 3 . In 31 it is shown in the course of insertion. The display 10 then preferably lies within the edge of the mounting part 45 ′, in particular within the peripheral edge of the mounting part 45 ′, directly on a rear side of the carrier part 3 .

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

The retaining tongue 54 is preferably designed in such a way that it bends open elastically, further retaining means are then not required. The display 10 is readily interchangeable.

In reference to figure 32 1 is a cross section through another embodiment of a housing, referred to herein as housing 12'. As can be seen in the cross section drawn, the housing essentially has a C-shape. The A continuous C-frame, which however preferably also has a viewing window 55 formed as a through-opening, is arranged on the front side of the carrier part in the assembled state. The C-legs 56 and 57 enclose the carrier part 3. The cooperation is preferably such that a clamping connection between the housing 12' and the carrier part 3 results. The housing 12' can easily be slid onto the carrier part 3 from above and moved to its desired place in terms of height.

A further frame part 59 is preferably attached to the rear of the continuous C-leg 58 on the inside, facing the carrier part 3 . In which the display 10, preferably in the form of the module already described, is removably accommodated. The frame part 59 is preferably formed circumferentially or at least on three or four sides with respect to the module 10, so that the module 10 cannot fall out onto the carrier part 3 even when the housing 12' is in place.

In this case, the support part 3 can be unaffectedly continuous, that is to say without a breakthrough.

Relating to Figure 33 An exploded view of the housing 12', the frame part 59 and the display 10 is shown.

In addition to the embodiment of Figures 26 and 27 a design is possible in which the resulting second layer 50, related to the longitudinal edge of the rectangular display board shown, but in this respect also generally, has a window-like recess in the overlapping area that corresponds to the opening 14 or at least the visible surface of the display 10, round but is designed to be closed around this opening, so that the adhesive film, which preferably forms the second film layer 50, surrounds the opening 14 in a closed manner and also seals it accordingly in the covered state. Thus, the edges of the film layer 51, which are formed on the underside by the film layers 50, are of different widths as seen in the width extension of the display panel. On the side on which the opening 14 is formed, there is a much greater width formed than on the opposite side. There is also a continuous film layer 50 in the area of the wide frame, so that there is very good adhesion between the second film layer and the carrier part when viewed over the length and height of the display panel.
