Description

[0001] The invention relates to a display panel, preferably for a motor vehicle price tender system as described in claim 1.

[0002] Display panels are already known in the art, consisting of a rigid, plate-like carrier plate or base plate, a backing on which an information element, in particular a price tag, data sheet, or the like, is placed, and a transparent, printable cover film. The cover film and the backing are bonded together. So-called adhesive films, preferably with an adhesive layer or soft PVC layer, are used as the cover film and backing to protect the inserted information elements. A disadvantage of this design is that, due to climatic influences, especially temperature and UV radiation, parts of the adhesive film (PVC component) melt and adhere almost inseparably to the surface of the substrate (aluminum composite (Alu-Bond), polycarbonate, etc.). Furthermore, the adhesive film becomes very hot, causing solvents to leach out and the printed ink to detach from the substrate.

[0003] For this reason, manufacturers of display panels are striving to offer solutions without adhesive films.

[0004] A self-contained display panel, as described in EP 4270368 A1, comprises a carrier plate with an opening through which a wirelessly controllable display is exposed. A cover sheet is inserted into a frame-like plug-in frame on the front of the carrier plate, the plug-in frame being open at the top. The display is detachably attached to the back of the carrier plate by means of fasteners. The display is removed essentially perpendicular to the surface of the carrier plate by releasing a fastening element without the need for tools.

[0005] In particular, the applicant seeks to protect the mounting and removal of the display. It is explained that the display can be removed essentially perpendicular to a surface extension of the support element, i.e., the base plate, by simply releasing a fastening element without tools. A disadvantage of this approach is that the display must always be secured to prevent it from falling when lifted vertically.

[0006] The object of the invention is to create a display board, preferably for a motor vehicle price tender system, in which, on the one hand, the aforementioned disadvantages are avoided and, on the other hand, a simple exchange of the cover sheet is possible.

[0007] Furthermore, the object of the invention is to enable the safe use of an electronic display.

[0008] The problem is solved by the invention, in particular by claim 1. Advantageous embodiments or process measures are described in the dependent claims.

[0009] The object of the invention is achieved by a display panel, preferably for a motor vehicle price tender system, in which the cover sheet is attached to the base plate in an interchangeable manner via preferably tool-free fastening means, in which the cover sheet has recesses corresponding to fastening points in the base plate and / or the cover sheet is attached to the base plate via an adhesive or adhesive tape.

[0010] A key advantage is that the cover sheet can be easily and quickly replaced thanks to the preferably tool-free fastening system. This allows for flexible adaptation to different content or promotions without the need for special tools or expertise. Because the cover sheet can be easily replaced, the need to replace the entire display board is reduced when only the displayed content needs updating. This saves on material costs and reduces the effort required for information updates. The rigid base plate ensures the necessary stability and durability of the display board, which is particularly important in public spaces where it may be exposed to various weather conditions.

[0011] Unlike conventional display boards that use adhesive films, this adhesive-free display board avoids the problems of melting and sticking due to environmental factors. This ensures a longer lifespan and more reliable use of the display board. The absence of adhesive films also eliminates issues with solvent leakage and flaking paint, resulting in improved temperature resistance and a more stable and aesthetically pleasing display board.

[0012] An advantageous design is one in which the cover sheet is attached to the base plate, preferably with four knurled screws and attached suction cups, for mounting on the inside of a vehicle window or windshield. This allows for easy, tool-free attachment of the cover sheet. Furthermore, the use of suction cups allows the display panel to be attached to a window, enabling customers to read all vehicle information from the outside. The suction cups allow the display panel to be easily attached to the inside of a vehicle window, allowing for flexible placement and ensuring that the information is clearly visible from the outside.

[0013] An advantageous design is one in which the cover sheet is attached using clamping devices, preferably with suction cups attached to them. This allows for easy, tool-free attachment and removal of the suction cups and the cover sheet.

[0014] An advantageous design is one in which the base plate is equipped with a clamping protrusion and the cover sheet is attached using preferably four knurled screws. This allows the display panel to be easily clamped behind the vehicle's dashboard.

[0015] A design with laterally arranged mounting projections on the base plate, to which the mounting elements, particularly suction cups, are attached, is advantageous. This design with mounting projections on the sides of the base plate, to which the mounting elements, particularly suction cups, are attached, offers a particularly stable and flexible mounting of the display panel. The lateral arrangement allows for an even distribution of the holding force across the suction cups, thus ensuring the display panel is securely and reliably fixed. This design also facilitates mounting and dismounting on smooth surfaces without having to directly touch the cover, ensuring a residue-free and gentle application. Therefore, the display panel is ideally suited for temporary and flexible applications, as it can be securely mounted and easily repositioned as needed.

[0016] An advantageous design is one in which the base plate has a clamping element for preferably lateral clamping between the windshield / glass and the body. This creates an additional mounting point.

[0017] However, a mounting method where the cover sheet is attached to the base plate using double-sided adhesive tape is also advantageous. This ensures that the entire surface of the base plate is available for the front, especially for the company logo. This is particularly beneficial for presenting logos or other important information. The invisible attachment ensures a clean and professional appearance for the display board.

[0018] A design with a mounting device on the base plate allows for the parallel insertion and removal of a display along the back of the base plate. This prevents the display from falling out vertically as it is inserted. The display can therefore be used without additional mounting, as it is preferably oriented for insertion from top to bottom. The mounting device for the electronic display and the recess in the base plate enable seamless integration of modern technology, allowing for the display of dynamic content. This enhances the appeal and interactivity of the display board. The replaceable cover sheet and the professional integration of the electronic display ensure a clean and attractive appearance, underscoring the professionalism of the presentation.

[0019] A design where the mounting bracket incorporates a centrally located, spring-loaded battery holder for inserting a suitably shaped display is advantageous. This allows the display to be significantly thicker in this area, enabling the use of appropriate batteries or rechargeable batteries. This reduces the need for external power sources and simplifies handling and installation. The ability to integrate batteries or rechargeable batteries directly into the display allows the display to operate independently. This increases the display's mobility and flexibility, as it can be used in various locations for extended periods without relying on external power sources. The spring mechanism ensures that the display is securely and stably fixed in the mounting bracket.This minimizes the risk of the display slipping or falling out, especially in moving applications such as in the automotive sector. The spring-loaded mounting element allows the display to be inserted and removed without tools. This simplifies handling and reduces the time required for installation and maintenance.

[0020] However, a mounting bracket with knurled screws that secures the display against falling out or accidental removal is also advantageous. This additional feature of the mounting bracket with knurled screws allows for easy, tool-free operation, enabling quick installation and removal of the display. The knurled screws ensure a secure fix, protect against theft and vandalism, and provide stability, even under vibrations or movements such as those that can occur in moving vehicles. These screws facilitate display replacement and maintenance, as they can be removed without special tools, and are compatible with various display types, increasing the flexibility of the display panel. Furthermore, the ergonomically designed knurled screws integrate seamlessly into the overall design and contribute to a professional appearance.In combination with the parallel insertion / extension mechanism, the knurled screws offer double security, maximizing the stability and safety of the display and making the display panel particularly user-friendly and reliable.

[0021] A design where the mounting bracket is glued and / or screwed to the base plate is advantageous. This ensures that the display is held securely in place, as the mounting bracket is firmly connected to the base plate. This secure attachment prevents the display from slipping or falling out and provides additional stability and safety, especially in applications in moving or public environments. The combination of gluing and screwing offers a particularly robust and reliable solution that guarantees the long-term use of the display panel.

[0022] A system is advantageous where the display can be wirelessly connected to a central unit, especially via Wi-Fi or Bluetooth, and the display, particularly the price and vehicle data, can be configured via the central unit. This allows the display data to be changed centrally at any time, enabling quick and efficient information updates. Furthermore, multiple display boards can be connected to a central unit simultaneously, significantly simplifying the management and coordination of the displays and increasing the flexibility and efficiency of the entire system.

[0023] A design where the mounting bracket has recesses / connection points that correspond to the systems located on the display is advantageous. This also makes it possible to connect the display to a central unit via cable, especially a data cable. This arrangement enables stable and reliable data transmission, which is particularly beneficial in environments with limited wireless connectivity. Furthermore, the fixed cabling ensures a constant power supply and data transmission, increasing the operational reliability and lifespan of the display. This solution offers flexibility in the choice of connection type and ensures that the system functions effectively even under challenging network conditions.

[0024] Finally, it is advantageous if the base plate is made of an aluminum composite or polycarbonate, as these materials offer high stability and durability. Aluminum composites are lightweight yet robust, making the display panel resistant to mechanical stress and weathering. Polycarbonate, on the other hand, is particularly impact-resistant and UV-resistant, ensuring that the base plate retains its shape and functionality even under intense sunlight. This choice of materials results in a durable and reliable display panel, ideally suited for use in various environments.

[0025] This type of display board can be used in various contexts, e.g., in vehicle price tenders, in sales rooms, at trade fairs, or in other presentation situations where rapidly changing and updated information is necessary.

[0026] The invention is subsequently described in the form of exemplary embodiments, whereby it is pointed out that the invention is not limited to the illustrated and described exemplary embodiments or solutions.

[0028] It should be noted at the outset that in the different embodiments, identical parts are provided with the same reference numerals or component designations, and the disclosures contained in the entire description can be applied analogously to identical parts with the same reference numerals or component designations. Furthermore, the positional designations chosen in the description, such as top, bottom, side, etc., refer to the described figure and must be applied analogously to any change in position.

[0029] In the Fig. Figures 1 to 11 describe application examples and schematic detail views of a diagram 1 according to the invention.

[0030] This includes in the Fig. 1 and Fig. 2 Two application examples of diagram 1 are shown behind a windshield 2 of a motor vehicle 3, the invention not being limited to these application examples. Fig. 1 The display panel 1 is attached inside 4 of the motor vehicle 3 directly to the windshield 2 or a side window by means of suction cups 5, while in Fig. 2. The display panel 1 is clamped behind the dashboard 6 of the vehicle 3. For this purpose, the display panel 1, in particular a support plate or base plate 7, has a clamping projection 8 that runs at an angle 9 of, for example, between 30° and 60° to the front surface 10 of the base plate 7. The clamping projection 8 can extend only over a portion of the length of the display panel 1, as will be shown later. Furthermore, a cover sheet 11 is arranged or attached to the front surface 10 of the base plate 7, which provides clearly visible information about the item for sale, such as a description and the price. This cover sheet 11 is designed so that it remains clearly visible even with different mounting methods for the display panel 1, for example, behind the windshield 2 or the dashboard 6.

[0031] In Fig. Figure 3 shows the diagram 1 according to the invention, which consists of the rigid base plate 7 and a replaceable cover plate 11. The cover plate 11 is attached to the base plate 7 in a replaceable manner by means of preferably tool-free fastening means 12. For this purpose, the cover plate 11 has recesses 14 which are arranged in the base plate 7 corresponding to the fastening points 13, in particular bores or threaded bores, as can be seen from the cover plate 11 before it is fixed. Fig. 3 is evident.

[0032] Preferably, the cover sheet 11 is attached to the base plate 7 by means of four knurled screws 15 with attached suction cups 5 for mounting on the inside of a vehicle window, in particular by screwing. It is also possible for the knurled screw 15 to be fastened with a knurled nut 15a. For this purpose, see below. Fig. Figure 3 shows a partially attached cover sheet 11 and the other part of the cover sheet 11 is shown lifted off.

[0033] Generally speaking, display panel 1, in particular the base plate 7 and the cover sheet 11, has a size, for example, A2, A4, or A5, etc. The cover sheet 11 is printed with data 16 and / or advertising 16, which may include, for example, the company logo and name, as well as data and sales price for the motor vehicle 3. It is also possible that transparent areas 17 are present on the cover sheet 11, allowing for the insertion of replaceable sheets underneath.

[0034] In Fig. Figure 3 shows a variant of display panel 1, in which the cover sheet 11 is provided with four suction cups 5 for attachment to a pane of glass. The suction cups 5 are positioned in the corner areas to minimize the impact on the usable surface area, particularly the advertising space. However, the number of suction cups 5 can be flexibly adjusted as needed, allowing for more or fewer suction cups 5 to be used for a stable attachment to the pane.

[0035] In Fig. Figure 4 shows another variant of display panel 1, in which it is attached to a disc 2 by a combination of two suction cups 5 and a special clamping element 18. The two suction cups 5 are arranged on one side of the display panel 1, while the clamping element 18 is attached to the opposite side of the base plate 7. The clamping element 18 is shaped as a projecting section 18a that occupies only a portion of the side length of the base plate 7. This allows the clamping element to be clamped to the edge of the disc 2, thus providing additional stability. To facilitate insertion onto the disc, the clamping element 18 is tapered towards the tip, allowing it to be easily and securely fixed to the edge of the disc 2. Once the clamping element 18 is positioned on the disc 2, the suction cups 5 ensure that the display panel 1 is held firmly in place on the disc 2.

[0036] In the Fig. 5 and Fig. Figure 6 shows an embodiment of the display panel 1, in which the cover sheet 11 is preferably removably attached to the base plate 7 with a heat-resistant adhesive or adhesive tape 19. This method of attachment allows the entire surface 20 of the cover sheet 11 to be fully utilized for data 16 and / or advertising messages 7 without being interrupted by visible fastening elements such as suction cups 5. To securely attach the display panel 1 to a disc 2, the base plate 7 is equipped with at least one, but preferably four, fastening projections 20. These fastening projections 20 accommodate the fastening means 12 in the form of suction cups 5, which ensure a stable attachment of the display panel 1 to the disc 2.

[0037] This shows the Fig. 5, that two fastening extensions 20 are located on opposite side surfaces of the base plate 7, while in Fig. 6. Only one fastening extension 20 is arranged on each of the side surfaces of the base plate 7. It should be noted that for larger formats of the display panel 1, such as DIN A2 format, a larger number of fastening extensions 20 may be provided to ensure sufficient stability. For smaller formats, such as DIN A5 format, however, only one to three fastening extensions 20 may be sufficient.

[0038] In another version, as in Fig. As shown in Figure 7, the cover sheet 11 can also be attached without adhesive. For this purpose, the cover sheet 11 is equipped with corresponding retaining extensions 22, which make it possible to securely fix the cover sheet 11 to the base plate 7 by mechanical fastening via the fastening means 12, in particular by means of the suction cups.

[0039] In the Fig. 8 and Fig. Figure 9 shows a variant of the display panel 1, in which the display panel 1 is clamped between the windshield 2 and the dashboard 6 by a clamping projection 8. This clamping device 8 ensures a stable positioning of the display panel in the vehicle 3 without the need for additional fasteners. The cover sheet 11 is attached to the base plate 7 with an environmentally friendly, heat-resistant, and removable adhesive or tape 19, as described previously, so that it can be easily replaced at any time.

[0040] Additionally, the stability of display panel 1 can be increased by using suction cups 5, as shown in Fig. Figure 9 shows that two suction cups 5 are preferably attached to the opposite longitudinal side of the base plate 7 to reinforce the hold of the display panel on the disc 2 and to ensure its position even during vehicle movements.

[0041] In the Fig. 10 and Fig. Figure 11 shows an application example of display panel 1 with an integrated electronic display 23. The display 23 is mounted on the back 24 of the base plate 7 and securely fixed by a special holding device 25.

[0042] To make the display 23 visible from the front of the display panel 1, a recess / opening 26 is provided in the base plate 7. This recess 26 allows the display 23 to be integrated directly into the viewing area of ​​the display panel 1. Additionally, the cover sheet 11 has a corresponding cutout 27 or, alternatively, a transparent area 27 that ensures an unobstructed view of the display 23. This allows the display 23 to be used for digital displays / information 28 with changing content, in addition to the data / advertising 16 on the cover sheet 11, without affecting the functionality or appearance of the display panel 1.

[0043] The holding device 25 of the display panel 1 is in Fig. Figure 11 shows in detail the electronic display 23, which is slidably mounted along the rear side 24 of the base plate 7 as indicated by arrow 29. This mounting device 25 allows the display 23 to be slid in and out parallel along the rear side 24, thus ensuring flexible and secure positioning. This prevents the display from falling out or being dropped, as is known from prior art when the display is lifted.

[0044] To securely attach the mounting device 25 to the base plate 7, it is either glued or screwed in place using adhesive tape 30. In the illustrated embodiment, the mounting device 25 is attached using adhesive tape 30. Furthermore, the mounting device 25 includes a centrally located, spring-loaded battery holder 31, which facilitates the insertion of a suitably shaped display 23. This allows displays 23 with large batteries or battery housings 32 to be used, eliminating the need for frequent charging or replacement. This enables the display 23 to operate for up to a month or more. The battery holder 31 also prevents the display 23 from slipping out. Additionally, the shape of the battery holder 31 can be adapted to the shape of the battery housing 32.

[0045] The display 23 can be additionally secured in the holding device 25 with screws, preferably knurled screws 33, which prevent the display 23 from unintentionally falling out or being removed. For this purpose, the holding device 25 has a bore 34 which corresponds to a threaded bore 35 on the back of the display 23.

[0046] Furthermore, the display 23 is connected to a central unit (not shown) via wireless technology, specifically WLAN or Bluetooth. This central unit allows for quick and easy adjustment of the displayed information 28, such as the price and vehicle data. This wireless connection enables flexible and efficient updates of the information on the display without requiring physical access. To allow the display 23, mounted on the display panel 1, to be connected to cables for charging, data transmission, etc., the mounting bracket 25 is provided with corresponding openings.

[0047] Naturally, the Display 23 can be used in all the variants shown.

[0048] It is noted that various materials can be used for the components of display panel 1. • Base plate 7: The base plate can be made of materials such as Alu-Dibond, PVC, acrylic glass or polycarbonate, aluminum or other plastics and metals to ensure high stability and durability. • Cover sheet 11: The cover sheet can be manufactured as a PVC sheet, PET film or polypropylene or other temperature-resistant transparent films to provide a clear and durable surface for displaying information and advertising. • Adhesive or tape 19: The adhesive 19 can consist of heat-resistant silicone adhesive, acrylic adhesive or a special removable adhesive tape 19 that allows a firm but removable attachment of the cover sheet 11 to the base plate 7.

[0049] As an alternative to the suction cups 5 with knurled screws 15 and knurled nuts 15a, self-adhesive suction cups 5 can also be used.

[0050] It is also possible for the cover sheet 11 to be attached to the base plate 7 by means of clamping devices (not shown), preferably with attached suction cups 5, which are slid laterally over the base plate 7 and the attached cover sheet 11. The suction cups 5 serve specifically to attach the display panel 1 to a pane 2, in particular a windshield 2. The cover sheet 11 is attached by simply pushing on the clamping devices, which are equipped with the suction cups 5 and ensure a stable, secure hold on the pane 2. This design allows for quick and easy attachment of the cover sheet 11, which can be easily removed or repositioned as needed without damaging its surface. It is also possible for the cover sheet 11 to be attached with such clamping devices instead of adhesive tape 19.

[0051] It should also be mentioned that the laterally arranged clamping element 18 can also be used in other embodiments of diagram 1. For this purpose, in Fig. Figure 8 shows the clamping element 18 with dashed lines in a version with a clamping projection 8. It is also possible that the clamping projection 8 has a double bend, as in Fig. 9 shown, can exhibit. For this purpose, the clamping projection 8 was now formed over the entire length of the base plate 7, which tapers towards the point.

[0052] For the sake of clarity, it should be noted that the invention is not limited to the embodiments shown, but may also include further developments. In particular, the embodiments or individual features of the embodiments can also be combined with one another. QUOTES INCLUDED IN THE DESCRIPTION
