Description

field of technology

The invention relates to a display board that can be handled independently, with a side length of 10 cm or more, up to, for example, 100 cm, for example a price display board, with a rigid, plate-like support part as a support for an information element, for example a written or printed film element, for example also sheets of paper, and/or a film element provided with an adhesive adhesive layer or designed thereby, wherein further the display board has a wirelessly controllable display with a layer forming visible characters, an opening further being formed in the carrier part through which the display is exposed, above In addition, an accumulator is assigned to the display.

State of the art

Display boards of the type in question are known from the prior art. For example, it will be on the DE 10 2016 109 619 A1 or even on the DE 10 2017 113 278 A1 , in addition, for example, also on the WO 2020/193705 A1 or the EP 3 029 658 A1 referred.

The display board can be arranged, for example, within a motor vehicle, further, for example, assigned to the inside of a windshield of the motor vehicle. The wirelessly controllable display can be designed in the manner of a known e-paper, for example to display price and/or product descriptions. Texts and images are preferably displayed permanently, without the need for a maintenance voltage. However, the display can be changed.

With regard to the prior art described above, the task arises of further improving a display board of the type in question in an advantageous manner.

According to a first inventive idea, a possible solution to the problem is given in a display board, in which it is intended that the display is releasably fastened by means of fastening elements on a visible outside of the carrier part opposite the outside of the carrier part, essentially vertically for possible removal of the display to a surface extent of the carrier part after a fixing interference of the fastening elements can be canceled without tools.

According to the proposed design, the display can be detached from the display board in a manner that is easy to handle, for example to replace the display. For this purpose, the display can advantageously be held on the display board via fastening elements, which fastening elements can preferably be brought into both the fastening grip of the display that provides the holder and also in a fastening grip lifting position without the use of a tool, such as a screwdriver. For this purpose, several fastening elements can preferably be provided for holding the display, for example two, three or four, but possibly more up to, for example, eight, ten or twelve.

A fastening element can, for example, be formed in the form of a locking tongue which can be extended transversely to the removal direction of the display, which in the fastening grip engages over an edge region of the display with a locking lug and to cancel this fastening grip against the Restoring force of a spring is movable. The locking arm of the locking tongue carrying the locking lug can have resilient properties depending on the appropriate choice of material.

It is also preferred that one, several or all of the fastening elements have an insertion bevel on the top, which triggers and ultimately automatically locks the display into a holding position by simply pressing on the display

Such a fastening grip can also be achieved, for example, by a manually operated, pivotable fastening element, which covers the edge area of the display with a section in the pivoted grip position.

In a further advantageous manner, after the fastening interference has been removed, there is the possibility of removing the display essentially perpendicular to a surface extent of the display board, in particular of the plate-like support part. In a further advantageous manner, this also enables the display to be removed or the display board to be equipped with a display even in a usage position of the display board, for example behind a windshield of a motor vehicle.

In a further approach to solving the problem, it is provided that the display board is designed to be placed on a surface that is flat for use, with a stand, and that the accumulator is arranged in or on the display board in the set-up state, assigned to the stand.

Due to the foot-side arrangement of the accumulator, a favorable center of gravity of the display board as a whole can be achieved, which makes the use of the display board supported in an advantageous manner as a display board. The display board can be supported on the facing surface of the subsurface in a point or line manner via the stand, but also optionally via a surface spanned by the stand.

The display board designed in this way is suitable, for example, for setting up on a piece of furniture, such as a table or shelf, but also, for example, for setting up on a floor. If necessary, it may even be possible to set up such a display board on the hood or roof of the vehicle being advertised.

Further features of the invention are explained below, including in the description of the figures, often in their preferred association with the subject matter of claim 1 or with features of further claims. However, they can also be of significance in an assignment to only individual features of claim 1 or the respective further claim or in each case independently.

According to a possible further development, the display can be provided with a substantially rectangular floor plan with an accumulator on the back of the display, which only takes up part of the base area of the display. Accordingly, an optionally step-like or wedge-shaped contour can be set on the back of the display with respect to a cross section, in particular perpendicular to a longitudinal extent of the display, with a depth dimension in the area of the accumulator that is larger than the other area. For example, with regard to the display or the entire display housing, in which, in addition to the area used for the display, further control elements and the like can also be provided, it can be viewed perpendicular to the longitudinal extent of the display Set a depth that can correspond to approximately 0.01 to 0.2 times, for example approximately 0.02 to 0.1 times, the longitudinal extent of the display. In the area of the accumulator, however, a total depth of the display and accumulator, including the surrounding housing or the housing surrounding the accumulator and the display together, can be set, which can correspond to approximately 2 to 5 times the previously described depth of the display or the display housing.

The accumulator can also occupy less than half of this base area, based on the base area of the display or display housing facing away from the visible side of the display. In a further embodiment, the size of the accumulator and/or the (partial) housing surrounding the accumulator is selected such that approximately a quarter to a third of the display base area is taken up.

In a further embodiment, the accumulator can be selected such that, when viewed transversely to the longitudinal extent of the display, the accumulator can extend over the entire base area width.

In a state of use, the display board is usually aligned in such a way that the support part of the display board is essentially vertical or including an acute angle of a few degrees, such as 3 to 10 degrees, up to, for example, 30 or 45 degrees, but in any case preferably less as 90 degrees, to a vertical or oriented to a vertical. In such a usage position of the display board, the above-described accumulator of the display is preferably arranged in an upper area of the display. Furthermore, the accumulator can connect to an upper edge of the display and, starting from this, extend in the longitudinal direction of the display or viewed in a substantially vertical extent over a partial area, for example over a quarter or a third of the base area of the display or the display housing.

The support part of the display board can have a housing wall on the back, correspondingly away from the usual visible side of the display board, which runs surrounding the display. The housing wall preferably forms an enclosure for the area of the display that projects beyond the rear surface of the carrier part or a display device comprising the display and the display housing, as well as the accumulator arranged on the display, as well as, if necessary, other electronic elements for the advantageous use of the display board.

In a preferred embodiment, the housing wall is designed as a plastic part, more preferably in the form of a plastic injection-molded part. The housing wall can be attached to the back of the carrier part on the carrier part, for example by gluing and / or screwing.

The housing wall can have an opening part, in particular for access to the display and/or the battery, which can be opened, for example, to remove the display. The lid-like opening part is preferably made of the same material as the housing wall and can be completely removable from the housing wall to release the opening of the housing wall that is initially closed by the opening part. In a further possible embodiment, however, the opening part can also be captively connected to the housing wall and can be arranged to be pivotable relative to the housing wall, for example about a formed hinge axis, in order to expose the above-described opening in the housing wall.

The opening part and the opening in the housing wall to be closed by the opening part are fundamentally dimensioned so that the display and/or the battery can be removed through the opening in a manner that is convenient in terms of handling and preferably without tools, particularly in a direction perpendicular to the surface extent of the carrier part can be.

Advantageously, the opening part can preferably be opened without tools. For example, the opening part can be provided with locking tongues that can be moved manually into a release position and which, when the opening part is closed, preferably automatically fall back into the closed and locking position. In this regard, for example, a hand-operated toggle-like screw cap can also be provided.

Two or more displays can also be held on the carrier part, for example up to three or four. If a plurality of displays are arranged, they can be chosen to be the same size with regard to their visible display area, but alternatively they can also be available in different sizes. With a possible arrangement of, for example, two displays, one display can be used to display the vehicle-specific data, while the other display can further display, for example, the current price and, if necessary, a current financing offer.

Each display is preferably assigned its own opening in the carrier part. Each opening can be adapted to the visible area of the display in terms of its length and width.

In addition, the carrier part can form an insertion tongue on an edge. In the usual position of use described above, this insertion tongue is preferably formed in the area of a downward-pointing edge of the support part, so that the insertion tongue can be used, for example, to hold the display board in the area of the opening slots provided on the bottom of the windshield in the usual dashboard area of a motor vehicle.

The display can have an antenna, in particular for receiving and/or sending data. When the display is installed in the display board, such an antenna can preferably extend behind a frame section of the support part. Accordingly, in a preferred embodiment, the antenna is in a protected, hidden position when viewed from the usual visible side of the display board. The antenna is usually part of the display or is arranged together with the display in or on the associated display housing and can be removed from the carrier part together with the display or assigned to the carrier part if necessary.

According to a preferred embodiment, the aforementioned frame section can be designed as a plastic part. Further preferred in this regard is a plastic injection-molded part which surrounds the opening for the display in the carrier part in a frame-like manner and is more preferably connected to the carrier part in the area of the opening edge. An adhesive or snap connection is preferred here.

Advantageously, the frame section can also have fastening elements for fixing, for example for locking, the display. Such fasteners can be used in the course of Production of the frame section must be made of the same material and in one piece with the frame section.

An embodiment in which the accumulator can be removed from the display also proves to be advantageous. This offers the possibility of replacing the battery without dismantling the display, as well as the possibility of charging the battery externally, while another charged battery can be assigned to the display in the meantime.

The battery can preferably be removed from the display without tools. For example, the accumulator can also be held in a snap-in manner on the display, for which purpose resilient locking tongues can be provided on the battery or on the display housing, which can interact with snap-in receptacles in the display housing or the battery.

With respect to a cross section through the display board perpendicular to the surface extent of the support part and with reference to the usual position of use of the display board described above, extending essentially in a vertically oriented plane, the support part, in a possible embodiment, forms a substantially wedge-shaped contour with the housing wall. In this case, a depth (thickness) of the display board viewed perpendicular to the surface extent of the support part, for example starting from an upper end region in the state of use, can decrease continuously or stepwise in the direction of, for example, a lower end region, more preferably having the above-described insertion tongue, down to a depth ( Thickness) of the display board, which can possibly only be defined by the material thickness of the carrier part or the insertion tongue. This can This extension, which results in the direction of the depth or thickness of the display board, can be reduced evenly or gradually over the entire extension dimension viewed essentially in the vertical direction in the state of use - if necessary without taking the insertion tongue into account. However, the reduction in the depth or thickness of the display board can also progress starting from an upper end region in such a way that, for example, two thirds or four fifths to five sixths of the relevant total extension length of the support part is reached when an extension in the cross section is reached starting from the upper end region , so that a lower section in the state of use, for example a third or fifth or sixth section, of the support part in the thickness direction can be defined solely by the support part itself. Alternatively, an inverted wedge-shaped cross-sectional design can also arise, with a small depth in the usual state of use upper area of the display board and a greater depth in the lower area.

The above-described cross-sectional contour of the display board proves to be particularly advantageous when arranging the display board in the interior of a motor vehicle, particularly on the inside of a windshield between the windshield and a dashboard area of the vehicle.

The display can have a manually operated switch for switching the display on and off. This can be, for example, a rotary or sliding switch, which can preferably be arranged on the display or the display housing and/or assigned to the accumulator, facing away from the usual visible side of the display board.

The switch described above can also be directly accessible through the housing wall or through the opening part of the housing wall. For this purpose, the housing wall or the opening part of the housing wall can have a corresponding opening through which the switch is detectably exposed.

In a further embodiment, an electrical button that can also preferably be manually operated can be provided on the display or associated with the display, via which the display can be reset if necessary.

Such a button can be arranged on the rear, opposite the visible outside, on the rear outside.

The button can act like a reset button. Such a reset proves to be important at the moment when the display board or the display in the display board is to be paired with the assigned vehicle, i.e. linked electronically.

Usually, image updates of the display are always carried out when the display itself, i.e. actively, asks for updates. In order to save energy, comparatively long cycles of several hours are usually preset. With normal use and arrangement of the display board, for example assigned to a vehicle, only one data update can take place per day. However, if the display is newly linked to a motor vehicle, for example, the image update must take place as quickly as possible in order to complete the pairing.

The display does not request any updates outside of the set cycles. The display also cannot be “woken up” via the software in order to do so Perform image update. For this purpose, the button (reset button) is provided, which "wakes up" the display through the user's voluntary action in order to enable the fastest possible image update.

In a further embodiment, a GPS receiver can be accommodated in the space between the housing part and the carrier part in addition to the one display or the multiple displays. The display board is equipped with such a GPS receiver to record the current position (latitude and longitude) of the display board and thus of the vehicle equipped with the display board, if necessary at regular intervals. The location data can either be transmitted automatically via the antenna to an external GPS location software or can be accessed as needed using such GPS location software or, for example, a smartphone location app, so that using this location data, for example, smartphone-supported guidance of an interested party can be reached to the vehicle in question.

The accumulator for the display, as well as each accumulator for each display or just one accumulator for all displays of the display board, can or can be arranged to be accommodated in the housing of the display board formed by the housing wall. In this regard, a complete receptacle can be provided within the housing.

In an alternative embodiment, the accumulator can also be designed as an attachment part comprising part of the housing wall. The attachment part that forms or receives the accumulator accordingly forms a housing sub-area in the arrangement and use position. This preferably results in an external arrangement with respect to the space enclosed by the housing as a whole Accumulators. Due to the selected arrangement, removal of the accumulator or equipping the display board with the accumulator can preferably be carried out without further opening of the housing.

The attached attachment part preferably complements the remaining housing to form an overall housing, more preferably taking up and continuing the given contour of the remaining housing.

The attachment part can, for example, be held in a snap-in manner on the rest of the housing wall. In this regard, a sliding connection between the attachment part and the rest of the housing wall is preferred. The attachment part can therefore have at least one rail-like projection, which can interact with a rail-like guide groove, for example with a dovetail-shaped cross section. The projection can also be provided on the housing side and the guide groove in the area of the attachment part.

In one possible embodiment, the sliding connection can be aligned transversely to a vertical orientation of the display board in relation to a usual position of use of the display board - in particular when using the display board as a stand-up display board. Accordingly, based on this set-up use position or vertical orientation, a sliding displacement of the attachment part that accommodates the accumulator or that directly forms it can result that can be carried out essentially in a horizontal plane.

Description of the embodiments

It is shown and described, initially with reference to the Figures 1 to 3 , a first embodiment of a display board 1, which is approximately rectangular Floor plan, with an aspect ratio of approximately 1:1 or 1:1.5 up to approximately 1:3 and an edge length of 10 to 100 cm, possibly longer. The display board 1 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. This support part 3 consists, for example, of an aluminum composite material. Alternatively, a solid aluminum part can also be present, possibly a carbon part or a part made of other solid plastic, for example polycarbonate.

An information element 5 can be arranged on one side of the carrier part 3, assigned to a visible outside 4. This can be, for example, printed paper.

Above and below, the “visible outside 4 or visible side” of the carrier part 3 refers to that outside of the carrier part 3 which faces the viewer in the state of use, on which the information element 5 is arranged if necessary - at least partially overlapping . For the designation "visible outside 4 or visible side" it is not important whether this side is actually visible when in use, but only that it is the side of the carrier part 3 that usually faces the user in the manner mentioned is.

The carrier part 3 can be covered with a plastic layer, for example with a polyester coating, in particular on the visible outside 4.

The information element 5 is preferably designed for interchangeable attachment or mounting on the visible outside 4 of the carrier part 3.

With a corresponding surface design of the visible outside 4 of the carrier part 3, the information element can be a printed film, which adheres to the visible outside 4 due to adhesion.

In this context, a frame-like plug-in receptacle is shown for holding an information element 5, for example a printed paper, in the area of the visible outside 4. For this purpose, a display board 1 in the usual position of use is provided on three sides Figure 14 Insert frame 6 that is open at the top is provided. Its frame legs 7, which preferably run parallel to one another, can extend along the side edges 8 of the support part 3, starting from an upward-pointing head-side edge 9. The frame web 10 connecting the frame legs 7 and running perpendicular to them extends in the exemplary embodiment shown at a distance a and aligned parallel to a foot-side edge 11 of the support part 3, which points downward in the position of use. The distance a can be approximately a fifth to a tenth correspond to the total vertical extension length b between the upper edge 9 and the lower edge 11 of the carrier part 3.

More preferably, a tab-like insertion tongue 12 is formed associated with the foot-side edge 11 of the carrier part 3 and connected to it in one piece using the same material. With this insertion tongue 8, the display board 1 can be mounted in a motor vehicle 2, for example by inserting it into a ventilation slot or in any case inserting it behind the windshield 13 (see Figure 14 ).

The display board 1 also has at least one display device D with a display 14. In the in the Figures 1 to 14 The first exemplary embodiment shown are two, essentially and preferably identical Display device D is provided, which are further held in a preferred side-by-side arrangement on the carrier part 3.

Each display 14 can preferably be controlled wirelessly and is further preferably designed in the manner of an e-paper.

For example, in one Figure 1 In the juxtaposition of two separate displays 14 shown, each display 14 can, for example, have a diagonal in the visible area of the display 14 (display area 23) of approximately 10 to 25 cm, further for example approximately 17 to 19 cm.

According to the representations in the Figures 15 and 16 A larger display 14 can also be provided, for example with a diagonal in the visible area of the display surface 23 of approximately 25 to 35 cm, further for example approximately 28 to 32 cm.

The display resolution is preferably more than 100 dpi, more preferably up to 126 dpi.

Essentially adapted to the surface extent of the display 14, there are 3 window-like openings 15 or 15 in the carrier part, in the exemplary embodiment according to FIG Figures 15 and 16 , a window-like opening 15 is formed, each with a substantially rectangular floor plan.

A frame section 16, preferably designed as a plastic part, is preferably fitted into the opening 15. A circumferential opening frame 17 of the frame section 16 extends in the use position on the inside edge of the opening edge of the opening 15, correspondingly reducing the opening 15 around the opening frame 17. The one left through the opening frame 17 The opening area is preferably adapted to the visible display area 23 of the display 14.

The surface of the opening frame 17 facing outwards towards the visible side can be essentially flush with the visible outside 4 of the carrier part 3 in the allocation position.

A contact edge 18 can be formed on the outside of the opening frame 17, by means of which the frame section 16 can be supported on the outside 19 of the carrier part 3, which faces away from the visible outside 4 and forms a rear side, all the way to the edge of the opening 15. In the area of this contact edge 18, the frame section 16 can be secured to the back of the support part 3, for example by gluing.

In the information element 5, according to the number of displays 14 or display devices D provided in the carrier part 3, openings 56 are left which are adapted and positioned to the respective floor plan extent of the display surface 23, through which the displayed display information can be read in the usual position of use of the display board 1.

The carrier part 3 or preferably the frame section 16 can also, as is also preferred, be the carrier of a plurality of fastening elements 20. The fastening elements 20 can, as in the exemplary embodiments shown, be spring-loaded locking tongues with gripping lugs 21 for locking the display or displays 14 or display devices D on the back of the carrier part 3 (see Figures 5 and 6 ). In the locking position, the gripping lugs 21 engage in a fastening grip on an associated edge of the display 14 or the display housing 22.

As can be seen, such a locking tongue can have an insertion inclined surface on the top, by means of which the display can be inserted into the holder and ultimately locked in place by simply pressing on the display.

The described locking of the display 14 enables the display 14 to be removed without tools in a direction essentially perpendicular to the surface extent of the carrier part 3 (see Figure 7 ). To cancel the fastening grip of the fastening elements 20, they are moved back against a resilient restoring force so far that their gripping lugs 21 release the associated edge edges of the display housing 22 (see dash-dotted illustration in Figure 5 ).

This makes both the assembly (including initial assembly) of the display 14 and removal, for example when changing the display, much easier.

The described arrangement and attachment of the display 14 or the display device D can lead to a plane offset of the display plane of the display 14 to the plane of the visible outside 4. The display plane of the display 14 can be set back relative to the plane of the visible outside 4, correspondingly recessed relative to the visible outside 4 by a thickness of the support part 4 and, if applicable, of the frame section 16 on which the display 14 is supported (compare Figure 6 ) be. In this way, increased breakage resistance of the display 14 can be achieved, especially in the case of stacking display boards 1.

On the back side facing away from the display surface 23 of the display 14, there is a device on the display housing 22 that ensures the operation of the display 14 Accumulator 24 provided and held. The accumulator 24 is preferably part of the display device D or can be assigned (electrically) to the display device D for operation.

This accumulator 24 is in a usual state of use, such as this one in Figure 6 or even in Figure 14 is shown, arranged in an upper area 25 of the display 14 or the display housing 22. The accumulator 24, preferably together with an accumulator housing 26 surrounding this accumulator 24, can occupy approximately a quarter to a third of the base area of the display 14 or the display housing 22 facing away from the display surface 23, more preferably essentially starting from an upper edge region 27 of the Displays 14.

In the area of the accumulator 24, i.e. in the upper area 25 of the display 14, there is a depth c of the display device D (including the respective housing) viewed perpendicular to the surface extent of the carrier part 3, which depth c is approximately 3 to 5 times can correspond to approximately 4 times the depth d viewed in the same direction in the lower area 28 defined solely by the display 14 or the display housing 22.

As further, especially in the representations of Figures 8 to 10 indicated, the accumulator 24 and the display 14 can be accommodated in a common housing.

The accumulator 24 can also, as in the Figures 11 and 12 shown, can be arranged to be removable from the display 14. For this purpose, a separate accumulator housing 26 can be used together with the one recorded Accumulator 24 can be snapped onto the display housing 22, for example. Correspondingly shaped locking projections 29, which are arranged, for example, on the battery housing 26, can correspond and cooperate with correspondingly positioned and shaped locking recesses 30, for example on the display housing 22. In the locking arrangement position according to Figure 11 There is electrical contacting of display-side contacts 31.

A preferably manually operated switch 32 is also provided to switch the display 14 on and off. As shown, this can be assigned to the accumulator 24 or the accumulator housing 26 and, as also shown, can optionally be designed as a sliding switch with a sliding movement direction e.

Furthermore, a button 73 in the form of a reset button can be provided on the back of the display D, corresponding to the outside 19. This can be accessible in the usual position of use through an opening 74 provided in the outside of the housing wall 33 in order to reset and/or activate the software to trigger an update or an update by direct manual operation or indirectly by using a tool, for example a pen-like tool To be able to create pairings.

A housing 34 with a housing wall 33 can be provided surrounding the display device D (or the plurality of display devices D) and preferably essentially covering it towards the outside 19. This can be a plastic injection-molded part, which essentially covers the outside 19 of the carrier part 3 like a hood.

The housing 34, which is essentially formed overall by the housing wall 33, is preferably connected to the carrier part 3 by means of screws 35.

The first according to Figure 4 Viewed in a floor plan on the rear outside 19 of the display board 1, the housing wall 33 arranged in a frame-like manner can be viewed with reference to the cross section in Figure 6 enclose an acute angle α of approximately 15 to 30 degrees to a perpendicular to the surface extent of the support part 3, at least in an area that is preferably upper when installed. The housing 34 extends with its housing wall 33 starting from the upper edge 9 of the support part 3 - when installed or in use - as well as the side edges 8 and at a distance from the lower edge 11, which distance can be selected to be smaller than that Distance a between the front frame web 10 of the insert frame 6 and the lower edge 11, so for example can correspond to approximately half the distance a.

Corresponding to the positioning of the accumulator 24 in the upper area 25 of the display 14, there is also a greater depth of the display board 1 overall - i.e. of the carrier part 3 together with the housing 34 - in relation to the housing 34 or the housing wall 33 delimiting the housing 34 upper panel area 36 than in a lower panel area 37, in which only the lower area 28 of the display device D has to be covered. In the lower area when installed or in use, a significantly larger angle can be realized corresponding to the angle α. For example, an angle of 20 to 60 degrees, preferably 30 to 50 degrees, more preferably 40 to 50 degrees and more preferably about 45 degrees.

This results in a preferred embodiment in the cross section according to Figure 6 a substantially wedge-shaped contour of the display board 1, with a wedge tip pointing downwards in the usual position of use. In this case, a step-like reduction in the depth (thickness) of the display board 1 viewed perpendicular to the surface extent of the support part 3 is further preferred, with ceiling sections 38 and 39 running essentially parallel or, at least with respect to the ceiling section 39, slightly rising to the surface extent of the support part 3 of the housing 34, wherein the ceiling section 38 assigned to the upper panel area 36 merges into the ceiling section 39 assigned to the lower panel area 37 via an inclined wall 40 which runs at an angle of approximately 45 degrees in cross-section.

Further assigned to the display device D and in perpendicular overlap therewith, a removal opening 41 is left in the housing wall 33, in particular in the ceiling sections 38 and 39. This allows the accumulator 24 and/or the display 14 or the display device D to be removed or inserted.

The removal opening 41 can be closed by an opening part 42 which is contour-adapted to the ceiling sections 38 and 39 and adapted to the removal opening 41. The removal or attachment of the opening part 42 is preferably carried out without tools. For this purpose, the opening part 42 can have lower gripping tabs 43 in a foot-side area for gripping under a lower edge area of the removal opening 41 (see Figure 6 ). In the upper edge region opposite these lower gripping tabs 43, the opening part 42 can carry locking tongues 44 for cooperation with the edge edge of the associated ceiling section 38.

The opening part 42, like the housing wall 33, can be designed as a plastic injection-molded part, and more preferably both the lower gripping tabs 43 and the locking tongues 44 can be made of the same material and in one piece with the opening part 42.

In addition to the associated accumulator 24, the display 14 or the display device D is further provided with functional elements (not shown in detail), such as a radio module and/or a control unit. Display 14, the accumulator 24 and the further functional element(s) can be arranged together in the display housing 22.

Other possible solutions provide for the display 14 and the functional elements to be housed in separate housings. In any case, the common arrangement within the space 49 formed between the housing 34 and the carrier part 3 is preferred.

As can be seen in particular from the illustration in Figure 6 As can be seen, the above-described manually operable switch 32 can be accessed and actuated through the housing wall 33, in particular through the opening part 42. For this purpose, in the exemplary embodiment shown, a window-like opening 45 is provided in the opening part 42, through which a handling part 46 that can be detected from the outside can enter into a positive connection with the switch 32. In order to remove the opening part 42, in one possible embodiment the handling part 46 can first be removed from the switch 42.

To protect neighboring parts when using the display board 1, for example parts of the dashboard area in a motor vehicle 2, as shown, in particular the rear lower section of the carrier part 3, which is not covered by the housing 34, and the rear surface of the insertion tongue 12 be covered by, for example, an adhesively attached fleece layer 55 (see Figures 4 and 6 ).

In the area of the upper thickened panel area 36, a recessed grip 47 can be formed in the housing wall 33, in particular in the upper ceiling section 38, for easy handling of the display panel 1.

Each display 14 preferably has an antenna 48. This is further preferably positioned in an edge region of the display surface 23 in the display 14 or the display housing 22 and, in the usual installed state, extends behind the frame section 16 designed as a plastic part, corresponding to one section the opening frame 17 of the frame section 16 is covered. The antenna 48 is thus protected from damage, starting from the visible side of the display board 1, by the frame section 16, but is not covered by an area of the support part 3.

At the in the Figure 18 The further embodiment shown differs from the exemplary embodiment described at the beginning (compare in particular the Figures 5 and 6 ) no direct locking of the display 14 or the display device D on the support part 3 or - as preferred - on the frame section 16 through direct interaction of the fastening elements 20 with corresponding edge regions of the display housing 22, but rather an indirect locking using the use and interposition of one or more - here two - clamping elements 58.

The clamping element 58 extends like a bridge in the arrangement and fixing position, the back of the display 14 or the Display device D with a tension web 59 spanning. Clamping legs 60 aligned essentially parallel to one another and perpendicular to the clamping web 59 adjoin the clamping web 59 on both ends.

Locking openings 61 adapted to the fastening elements 20 or their gripping lugs 21 are formed in the clamping legs 60.

Each clamping element 58 can be designed as a plastic injection molded part.

To fix the display 14, it is placed on the back of the frame section 16. If necessary, support tabs 57 formed further on the frame element 16 provide a positioning aid and, in normal use of the display board 1, a support for the display 14. The display 14 is fixed by means of the clamping elements 58, which interact with the fastening elements 20, if necessary via the bridge-like clamping elements 58 whose elastically resilient design can be used to build up a spring and tension force acting on the display 14 and loading it against the frame section 16 - or, in the case of a direct arrangement without a frame section 16, against the support part 3.

In Figure 20 an embodiment of the display board 1 is shown, in which, as can be seen, the lower panel area 37 assigned to the edge 11 in the area of the housing 34 has a greater depth c, viewed perpendicular to the surface extent of the support part 3, than the upper panel area 36 assigned to the edge 9. Result So in the exemplary embodiments described at the beginning - primarily due to the preferred usage arrangement behind a motor vehicle windshield 13 in the dashboard area - the housing design (and arrangement of the accumulator) is rather top-heavy. can be seen in the embodiments of Figures 20 to 23 a more foot-heavy design.

In the foot-side housing area provided with the greater depth, the mentioned removal opening 41 can be provided, which can be closed by an opening part 42 in the embodiment shown in FIG.

Through the removal opening 41, for example, an accumulator can be arranged in the space 49 or removed from the space 49, as can other components such as those mentioned above or below.

Facing the lower edge 11, the housing 34 can form a mounting foot 72, in particular with two foot-like mounting legs 63, which mounting legs 63 with respect to a cross section through the display board 1 or with reference to a side view against the display board 1 as shown in Figure 21 can extend essentially in a V-shape, spread apart from one another.

In the in Figure 21 In the illustrated usage position of this embodiment, the display board 1 can be supported in a line-like manner via the stand legs 63 on a preferably horizontal and flat surface 71. This further preferably results in an alignment of the visible side of the display board 1, in which the surface of the support part 3 facing the visible outside 4 encloses an acute angle β of approximately 15 to 45 degrees, for example approximately 30 degrees, to a vertical in a vertical cross section .

The preferred thickening of the housing 34 in the foot area and the further preferred arrangement of the accumulator(s) for the one or more displays 14 in this area results in a comparatively low center of gravity of the display board 1 as a whole, which leads to a stable orientation of use.

Also according to the representations in the Figures 22 and 23 the housing 34 - in particular assigned to the foot area which is larger in depth - has an insertion area 64 for receiving and arranging an attachment part 68 which preferably contains or forms the accumulator on the outside of the housing. The insertion area 64 can, as shown, end open at the edge towards a side edge 8 . Opposite this open-edge end, there is preferably a delimitation by a housing-side wall 66.

For the guided insertion of the attachment part 68 into the sliding connection, one or more - here two - insertion grooves 65 are formed in the insertion area 64 on the housing wall side. One of these insertion grooves 65 can be formed on the bottom side of the insertion area 64 and a further insertion groove 65 in the area of the surface of an associated mounting leg 63 facing the insertion area 64.

The insertion grooves 65 also run open towards the side edge 8.

The attachment part 68, which is provided with insertion projections 69 corresponding to the insertion grooves 65, can, as is also preferred, be designed to be contour-adapted to the housing area surrounding the insertion area 64, so that in the insertion position, an optical unit results overall through the housing 34 and the attachment part 68.

In the exemplary embodiment shown, two plug-in openings 67 are formed in the wall 66 described above. Only one such plug-in opening can be provided or more than two plug-in openings can be provided.

The plug-in openings 67 can be designed to lock the attachment part 68 in the inserted position by the plug-in openings 67 interacting with projection-like plug-in connections 70 of the attachment part 68. As is further preferred, electrical contact can also be achieved via this plug connection.

As a result of the design described above, the accumulator is directly accessible from the outside in a way that is convenient to handle and can preferably be replaced, for example, without opening the housing 34.

The display 14 or the display device D is designed for wireless control or for wireless acquisition of data. An image of the display 14 is created based on the data received.

The data for generating the image to be displayed is preferably stored and held in a dedicated database of a wirelessly connected computer system 52. This can, as is also preferred, be a cloud-based database.

The display device D of the display 14 can be designed for bidirectional data exchange.

In the preferably cloud-based computer system 52, dynamic image data generation can take place based on data sets. Accordingly The image can be generated and transmitted and shown on the display 14.

The display device D of the display board 1 preferably has a unique Internet and/or mobile phone ID, and in particular a unique physical address.

A common mobile radio standard can be used for wireless communication, such as NB-IoT or CaT-M1.

Furthermore, the display board 1, in particular the display device D of the display 14 or assigned to the display device D, for example in the space 49 resulting between the housing wall 33 and the carrier part 3, a plug-in board can be provided, with one or more slots in which slots For example, a mobile radio module or alternatively or in combination with this a positioning module, for example in the form of a GPS receiver 50, can be plugged in.

The GPS coordinates of the display board 1 can also be saved in the cloud or the computer system 52. This also offers the possibility of retrieving these GPS coordinates and, if necessary, a coordinate progression over a predetermined period of time using a terminal 51, for example a smartphone. This terminal 51 is also preferably in bidirectional contact with the computer system 52.

With regard to the wireless connection between the terminal 51 and the computer system 52, as well as between the computer system 52 and the display board 1, it can be a full-duplex or half-duplex mode.

For example, a travel path of the motor vehicle 2 provided with the display board 1 can also be recorded using the GPS function and stored in the computer system 52.

In particular, in order to save energy for the preferably battery-operated display device D, an image is created or a new image is created of the display 14 at a greater time interval than corresponds to the time interval with regard to the data transmission to the image structure of the display 14. For example, a regular image refresh can take place every quarter of an hour, half an hour or even hourly.

To directly carry out an image structure or new image structure, the display device D of the display 14 can also be controlled separately, for example remotely using the computer system 52 or the terminal 51. For this purpose, as well as for carrying out further functions or for retrieving information, an on the computer system 52 (here cloud) stored application can be used, which can be operated via a common browser on the end device 51.

In order to immediately carry out an image structure, a corresponding command can be directed to the display device D via the computer system 52 via the application using the terminal 51.

The display board 1 can also have an acceleration/motion sensor. By means of this, a possible movement of the display board 1, for example the removal of the display board 1 from the motor vehicle 2, can be detected and reported to the computer system 52 via the radio module.

A movement of the display board 1 and/or the motor vehicle 2 together with the display board 1 detected by the acceleration/motion sensor can also cause data transmission via the radio module directly or indirectly via the computer system 52 to an alarm system to trigger an alarm.

The acceleration/motion sensor can also be used to generate a command to immediately recreate the image of the display 14. For this purpose, according to a possible embodiment, the display board 1 can be shaken or moved back and forth. This movement of the display board 1 is detected via the acceleration/motion sensor, as a result of which a corresponding signal is generated.

In addition, the acceleration/motion sensor can be configured, for example via the computer system 52, for certain areas, for example the sales area G, and/or for certain time periods (for example on weekdays during business hours).

Advantageously, such an acceleration/motion sensor can also detect the resulting acceleration of a fall of the display board 1, in particular the display 14, and store the recorded values in the preferably cloud-based computer system 52. Falls of the display board - and any resulting breakage of the display - can be recorded in this way.

In a further possible embodiment, the application used via the terminal 51 can have a search mode, via which the operator of the terminal 51 can search, for example, on a larger sales area G (compare, for example, by specifying certain search criteria). Figure 24 ) one or several motor vehicles 2 corresponding to these search criteria can be found.

For this purpose, on the one hand, the GPS receiver 50 of the display board 1 can be used, so that the user is guided to the motor vehicle 2 with the terminal 51, in particular a mobile terminal 51 in the form of a smartphone or the like.

The data recorded by the GPS receiver 50 offers an accuracy of approximately 5 to 10 m, particularly in outdoor areas, so that the user can be guided close to the motor vehicle 2 he is looking for using the mobile terminal 51.

Alternatively or in combination with this, in particular to support the GPS guidance, especially in the outdoor area, a lighting element 53 can also be provided on the display board 1, for example in the form of an LED. The lighting element 53 is activated via the computer system 52 as soon as the assigned motor vehicle 2 corresponds to the search profile entered via the app.

The lighting element 53 can light up permanently if activated appropriately or, for example, flash rhythmically.

In a further alternative or combinational embodiment, the display board 1 can be equipped with Bluetooth transmitters 54 based on iBeacon technology for precise localization of the display board and thus of the motor vehicle 2 equipped with it - preferably both indoors and outdoors. For example, this can be assigned to room 49 and in the state of use Covered by the opening part 42, a receiving pocket 62 can be formed on the housing side (cf Figure 19 ).

Such energy-saving iBeacon transmitters 54, for example GPS, low-power GPS, Wi-Fi sniffer, Bluetooth Low Energy (BLE) or Bluetooth Smart Technology and LoRa (Low-Power Wireless) - TDoA (Time Difference of Arrival) - Geolocation technologies can combine, offer a localization accuracy of approximately 3 to 5 cm, so that precise guidance of the user can be achieved with the help of the mobile terminal 51 (for example smartphone).

For example, a plurality of motor vehicles 2, each with a display board 1, can be positioned in a room, which display boards 1 are each provided with such an iBeacon transmitter 54 (see Figure 25 ).

In addition, such iBeacon transmitters can also be installed in the room (stationary).

The transmitters 54 send out signals at predetermined time intervals that can be identified by a receiver that comes within the range of the transmitters, for example a mobile terminal 51 (further, for example, a smartphone with an installed application). The recorded signal strength can also be measured and evaluated.

By means of trilateration, for example, the position of the receiver - here the terminal 51 - within the two-dimensional space can be determined when three iBeacon transmitters 54 are detected (compare Figure 25 ). If four iBeacon transmitters 54 are detected simultaneously, the positioning within a three-dimensional space can even be calculated.

With an application installed on the user's end device 51 or with a corresponding cloud-based application, visitor flows can be recorded in the display board using provided iBeacon transmitters 54 and subsequently evaluated.

In areas where the commonly used radio signal is too weak for communication between the display board 1 and, for example, a mobile terminal 51 or between the display board 1 and the computer system 52 (for example in the area of underground car parks) or, for example, in locations with moderate to no NB -IoT coverage, the signal can be strengthened through, for example, WiFi support.

When using a cloud-based application, no software installation on the terminal device 51 is advantageously necessary. Rather, the user can use the data via a browser application and, if necessary, change it.
