Description

[0001] title

[0002] Mounting system for the flexible attachment of electronic display devices for displaying product information and / or price information on a mounting wall

[0003] Technical field

[0004] The present invention relates to an electronic display device, a mounting wall for flexibly attaching the at least one electronic display device, and a mounting system for flexibly attaching electronic display devices for displaying product information and / or price information.

[0005] background

[0006] Product information and prices can be displayed on electronic display units, known as "Electronic Shelf Label" units (ESL units). These ESL units feature a display screen that can show different and changing information. Furthermore, ESL units can have an internal power supply (via battery) or be connected to an external power source.

[0007] ESL units can be arranged in multiples and used to present one or more products and their information. They can also be mounted on a common surface, such as a wall. Such walls are commonly used at trade show booths to present the various ESLs in a clear and organized manner.

[0008] Currently, double-sided adhesive tape is simply applied to the wall. The same is done on the back of the ESL units. Using these double-sided tapes, the ESL units are then attached to the wall surface. Even if the ESL units are initially properly aligned at the start of the trade fair, the problem arises that, as the fair progresses, the units are repeatedly removed and reattached to show and highlight details. This leads to misalignment, negatively impacting the overall appearance of the ESL presentation. Furthermore, due to their weight, the ESL units tend to lift away from the wall at the top, even if their bottoms are flush, resulting in a three-dimensional distortion of the display.

[0009] Summary of the invention

[0010] It is an object of the present invention to provide a fastening system for ESL units with which the ESL units can be fixed robustly and in a desired orientation.

[0011] This task is solved by means of an electronic display device, a mounting wall and a fastening system, and a method for flexibly attaching electronic display devices for displaying product information and / or price information in accordance with the independent claims.

[0012] According to a first aspect of the invention, a mounting wall is described which is designed for the flexible attachment of at least one electronic display device, in particular for displaying product information and / or price information. The mounting wall has at least one receiving opening in which the electronic display device can be at least partially received such that a fastening element secures a fastening section of a base body of the electronic display device to a contact area of ​​the mounting wall for securing the electronic display device in the receiving opening. According to a further aspect of the invention, an electronic display device, in particular for displaying product information and / or price information, is described which is designed for flexible attachment to a mounting wall.The electronic display device comprises a base body and a screen, which is integrated into the base body and visible from a display surface of the base body. The base body has a mounting section located opposite the display surface. The electronic display device (and in particular the base body) is designed such that it can be at least partially inserted into a receiving opening in a mounting wall, and that the mounting section can be fastened to a contact area of ​​the mounting wall in the receiving opening by means of a fastening element.

[0013] According to a further aspect of the invention, a system for the flexible mounting of electronic display devices, in particular for displaying product information and / or price information, is described. The system comprises an electronic display device with a base body and a screen which is received in the base body and is viewable from a display surface of the base body. The base body has a mounting section which is formed opposite the display surface.

[0014] Furthermore, the system comprises a mounting wall which has at least one receiving opening in which the electronic display device (and in particular its base body) can be at least partially received such that a fastening element secures the mounting section to a contact area of ​​the mounting wall for securing the electronic display device in the receiving opening. According to a further aspect of the invention, a method for flexibly attaching at least one of the above-described electronic display devices to a mounting wall described above is presented. According to this method, the electronic display device is received into a receiving opening of a mounting wall such that a fastening element secures the mounting section to a contact area of ​​the mounting wall for securing the electronic display device in the receiving opening.

[0015] The electronic display device, which is in particular an "Electronic Shelf Label" unit (ESL unit), has a base body or frame that completely or partially surrounds the functional units of the display device. The base body can, for example, be designed as a housing and may include, as functional units, the power supply unit (battery), the control unit (microprocessor, CPU), and / or the communication units (transmitter and / or receiver units). The base body also surrounds the display device's screen without covering it, so that the display device can be viewed from the outside. The base body is made in particular of a solid material, such as metal (aluminum) or plastic.

[0016] The electronic display device can, for example, be controlled by an external control unit, so that various image content (price information, product information) can be displayed on the screen.

[0017] The mounting wall can have a round, oval, or polygonal shape, such as a rectangle. It can also have a stand for placement on the floor. This stand can, for example, have casters, allowing the mounting wall to be moved along the floor. Furthermore, the mounting wall can be designed for installation on a load-bearing wall, such as a building wall. For this purpose, the mounting wall can have openings through which a fastener, such as a nail or screw, can be inserted.

[0018] The mounting wall has a sufficient thickness to accommodate one or more receiving openings for the electronic display device. These receiving openings can be arranged in a specific pattern along rows and columns, allowing one or more electronic display devices to be mounted and secured at any given opening. The mounting wall can be made of a natural material such as wood, metal, or a rigid plastic. The receiving openings can be created, for example, by drilling, cutting, or milling.

[0019] The mounting holes in the wall are designed to allow the electronic display device to be at least partially or completely received. This allows the electronic display device to transfer at least some of its weight directly into the mounting wall via the mounting hole, ensuring a secure fit within the mounting hole and the wall itself. The shape of the mounting hole also provides a degree of alignment for the display device. This makes it difficult to remove the electronic display device from the mounting wall, particularly from the mounting hole, as the device is at least partially contained within the hole.

[0020] In particular, the contour of the receiving opening can be adapted to a corresponding contour of a receiving area of ​​the electronic display device in such a way that an interference fit (e.g., a clearance fit, transition fit) is provided, thus creating a press fit between the mounting wall and the receiving area of ​​the electronic display device within the receiving opening. The receiving area of ​​the electronic display device defines the area or its outline that is present in the receiving opening when the display device is attached to the mounting wall. This creates a secure and releasable fastening of the display device in the receiving opening, in addition to providing the fastening element. Due to a predetermined contour / outline of the receiving opening (e.g., oval or polygonal) and a corresponding orFurthermore, by using the corresponding contour of the recording area of ​​the electronic display device, a desired alignment of the electronic display device can be achieved, so that manual alignment of the display device is not necessary.

[0021] The receiving openings can have different contours to accommodate different designs of electronic display devices.

[0022] To reinforce the attachment of the electronic display device to the mounting wall, a fastening element is also provided. This fastening element is specifically designed for the detachable attachment of the electronic display device to the mounting wall. Detachable attachment is understood to mean attachment whereby the connecting parts can be repeatedly and non-destructively separated and reattached. The fastening element is specifically located at a contact area on the mounting wall where a corresponding mounting section of the base body of the electronic display device is placed. The fastening element can, for example, be located at a contact area in the receiving opening or on the mounting section of the electronic display device that rests on the surface or is located in the receiving opening.

[0023] In another exemplary embodiment, the fastening element comprises a first connecting component and a corresponding second connecting component, wherein the first connecting component is arranged on the mounting section of the electronic display device and the second connecting component is arranged on the contact area of ​​the mounting wall, for example on its surface or within the receiving opening. Both connecting components are further configured to generate a detachable connection with each other, for example in the sense of a hook-and-loop fastener system as described in more detail below, or also a button system, zipper system or adhesive system.

[0024] The present invention thus provides a mounting system for electronic display devices, enabling them to be robustly fixed partially within the receiving opening in a desired orientation. Due to the arrangement of the receiving openings at different locations, the mounting wall can accommodate a corresponding electronic display device, allowing for a desired configuration of electronic display devices.

[0025] According to another exemplary embodiment of the mounting wall, the fastening element is arranged at the contact area. Thus, for example, the electronic display device can be free of a fastening element and achieve fixation by bringing the fastening section into contact with the fastening element at the contact area. The electronic display device can, for example, be detached from the fastening element, leaving the fastening element in place at the contact area. Therefore, the electronic display device does not need to be provided with fastening elements, as these are already present in the contact areas of the mounting wall. This simplifies the provision of the electronic display device and also facilitates easier handling.Storage, as it reduces the risk of a fastener becoming stuck in an unwanted position (for example, with a fastener of another electronic display device).

[0026] According to another exemplary embodiment of the mounting wall, the fastening element forms an adhesive tape, in particular a double-sided adhesive tape. Forming the fastening element as an adhesive tape provides a convenient and quickly positionable fastening option.

[0027] According to another exemplary embodiment of the mounting wall, the fastening element is a magnetic element designed such that a magnetic attachment with a corresponding magnetic element of the electronic display device can be established. The magnetic element is attached to the contact area, for example, by means of an adhesive. Furthermore, the magnetic element can be embedded in the material of the mounting wall in the immediate vicinity of the contact area. In an exemplary embodiment of the electronic display device, the corresponding magnetic element of the electronic display device is formed, in particular, on or in the immediate vicinity of the mounting section of the electronic display device.The magnetic element of the electronic display device can, for example, also be formed by the base body of the electronic display device, in which it is made of a magnetically reversible material, for example metal, or in which a corresponding magnetic element is embedded or attached in the base body.

[0028] According to another exemplary embodiment of the mounting wall, the receiving opening is adapted to the contour of the base body in such a way that the base body can be received in the receiving opening in a non-displaceable and, in particular, rotationally fixed manner. Due to a predetermined contour or outline of the receiving opening (for example, oval or polygonal) and a corresponding contour of the receiving area of ​​the electronic display device in the receiving opening, a desired alignment of the electronic display device can also be achieved, so that manual alignment of the display device is not necessary.

[0029] According to another exemplary embodiment of the mounting wall, the receiving opening is designed such that the base body of the electronic display device can be partially received in the receiving opening, and the base body can project out of the receiving opening from the surrounding surface. In other words, the receiving opening is designed such that only a portion of the base body is located within the receiving opening. Another portion of the base body, which, for example, surrounds the screen, projects out of the receiving opening or protrudes from a surface adjacent to the receiving opening. For example, the portion of the base body located outside the receiving opening can have a larger diameter or area than the diameter or cross-sectional area of ​​the receiving opening, so that the projecting portion of the base body rests on a corresponding surface of the mounting wall.The section of the base body that is located in the receiving opening can have a diameter that is correspondingly smaller than or smaller than the receiving opening.

[0030] According to another exemplary embodiment of the mounting wall, the receiving opening is designed such that the electronic display device can be completely received within the receiving opening, with the screen of the base body being able to be arranged flush with a surrounding surface of the mounting wall. In particular, a homogeneous surface can be created along a surface of the mounting wall over the electronic display devices arranged within it. The electronic display devices are particularly well protected by being completely enclosed within the receiving openings. The size of the receiving opening can be dimensioned as follows: On the one hand, the receiving opening can be defined to receive a base body or a functional section of the base body, which includes functional units such as a battery or the battery cover.In this case, the edge of the screen that extends beyond the functional section can lie against the front of the mounting wall.

[0031] Furthermore, the mounting opening can be designed to accommodate the screen and its bezel. In this case, the screen also appears recessed into the mounting wall. The front of the screen can still be positioned slightly raised from the front of the mounting wall. The depth of the display device's placement within the mounting opening can be varied, allowing the screen's front to be flush with the front or surface of the mounting wall. Finally, to prevent unauthorized removal, the front of the screen can even be positioned slightly below the front or surface of the mounting wall.

[0032] According to another exemplary embodiment, the receiving opening is designed as a blind hole in the mounting wall. Accordingly, a predetermined seat or positioning at a specific depth within the receiving opening for the electronic display device can be defined.

[0033] According to another exemplary embodiment, the contact area is formed at the bottom of the blind hole. The mounting section of the electronic display device is arranged such that, when the electronic display device is positioned in the receiving opening, the mounting element between the mounting section and the contact area enables fixation.

[0034] According to another exemplary embodiment, the

[0035] The receiving opening is designed as a through-hole in the mounting wall. This allows a variety of differently designed electronic display devices, particularly those with varying depths, to be installed in a single receiving opening without, for example, an insufficient hole depth in a blind hole causing the electronic display device to protrude.

[0036] According to another exemplary embodiment, the through-hole is closed with a contact element of the mounting wall, wherein the contact element has a contact area with the mounting element of the electronic display device. The contact element can, for example, be a film-like element that is attached to a rear surface of the mounting wall and closes the receiving opening. The rear surface of the mounting wall is the surface that faces the surface along which the screen of the electronic display device is visible. The contact element can, for example, be an adhesive film and thus simultaneously be part of the mounting element. When the mounting section of the electronic display device contacts the contact area on the adhesive film as the contact element, a corresponding fastening can be achieved.

[0037] According to another exemplary embodiment, the contact element is fixed to the mounting wall by means of an adhesive bond. Alternatively, the contact element can also be fixed to the mounting wall by means of a screw connection or a stapler connection.

[0038] According to another exemplary embodiment of the mounting wall, the contact area is formed on a surface of the mounting wall that surrounds the receiving opening and on which the base body of the display device can be placed. Similarly, in another embodiment of the electronic display device, the mounting section of the electronic display device can be placed on a surface of the mounting wall surrounding the receiving opening, and the contact area with the mounting element is formed on the surrounding surface.

[0039] In other words, the contact area is not located within the receiving opening, but rather outside of it on a surface surrounding the receiving opening. The base body of the electronic display device can, for example, be T-shaped or mushroom-shaped, with the screen forming the thicker section and the narrower section located within the receiving opening. The mounting element can thus be located, for example, outside the receiving opening, between the contact area and the mounting section of the base body.

[0040] In a further exemplary embodiment, in addition to the contact area described above outside the receiving opening, a further contact area can be provided inside the receiving opening, so that several contact areas enable attachment to corresponding mounting sections of the electronic display device. Accordingly, several identical or different mounting elements can be provided between the corresponding mounting sections and contact areas.

[0041] According to a further exemplary embodiment, the mounting wall has a plurality of further receiving openings in which the electronic display device, or at least another electronic display device, can be received at least partially such that a corresponding fastening element of the electronic display device to be received secures a fastening section with a further contact area of ​​the mounting wall for securing the corresponding display device in the further receiving opening. According to a further exemplary embodiment of the electronic display device, the fastening element is arranged on the fastening section. Thus, for example, the mounting wall can be free of a fastening element and achieve fixation by bringing the contact area into contact with the fastening element on the fastening section.The electronic display device can, for example, be detached from the contact area together with the mounting element, while the mounting element remains attached to the mounting section. Therefore, the receiving openings or contact areas of the mounting wall do not need to be fitted with mounting elements, as these are integrated into the electronic display device.

[0042] According to another exemplary embodiment of the system, the fastening element comprises a first connecting component and a corresponding second connecting component of a hook-and-loop fastener system, wherein the first connecting component, in particular a loop or felt strip element, is arranged on the fastening section and the second connecting component, in particular a hook strip element, is arranged on the contact area of ​​the fastening wall. Furthermore, the first connecting component can also comprise a hook strip element and the second connecting component a loop or felt strip element. Thus, a hook-and-loop fastener system is provided that can be opened and closed almost any number of times. The hook strip element has correspondingly small, flexible barbs, and the loop or felt strip element has correspondingly small loops.When compressed, the connecting components form a durable yet reversible quick-release fastener. The woven hook-and-loop fasteners can be made of polyamide, polyester, or polyolefin fibers. The second connecting component at the contact point can, for example, be formed on the contact element that closes the receiving opening as a through-hole, or it can be formed on the bottom of a blind hole in the receiving opening.

[0043] Finally, it should be mentioned that the described mounting wall is used for presentation purposes, specifically for displaying electronic display devices; thus, according to a preferred embodiment, it is a presentation wall for electronic display devices. According to a particularly preferred embodiment, it is a trade fair booth presentation wall that is integrated into the structural elements of a trade fair booth, i.e., adapted to the existing fixtures.

[0044] It should be noted that the embodiments described here represent only a limited selection of possible embodiments of the invention. It is possible to combine the features of individual embodiments in a suitable manner, so that a multitude of different embodiments are considered to be obviously disclosed to the person skilled in the art with regard to the embodiments explicitly described here.

[0052] Fig. 7 shows a schematic representation of a mounting section of an electronic display device, according to an exemplary embodiment of the present invention. Description of the exemplary embodiments

[0053] Identical or similar components in different figures are identified by the same reference numbers. The representations in the figures are schematic.

[0054] Fig. 1 shows a schematic representation of a system 150 for the flexible mounting of electronic display devices 120, in particular for displaying product information and / or price information. The system 150 comprises an electronic display device 120, including a base body 121 and a screen 122, which is received in the base body 121 and is visible from a display surface of the base body 121. The base body 121 has a mounting section 123, which is formed opposite the display surface. The system 150 further comprises a mounting wall 100, which has at least one receiving opening 101 in which the electronic display device 120 can be received, at least partially, such that a fastening element 110 secures the mounting section 123 with a contact area 102 of the mounting wall 100 for fastening the electronic display device 120 in the receiving opening 101.

[0055] The mounting wall 100 has a sufficient thickness to accommodate one or more receiving openings 101 for the electronic display device 120. In the exemplary embodiment shown in Fig. 1, the receiving opening 101 of the mounting wall 100 is designed such that the electronic display device 120 can be partially received. This allows the electronic display device 120 to transfer at least some of its weight directly into the mounting wall 100 via the receiving opening 101, ensuring a secure fit of the electronic display device 120 within the receiving opening 101 and the mounting wall 100. The shape of the receiving opening 101 also provides a degree of alignment for the display device 120.Unwanted or even spontaneous detachment of the electronic display device 120 from the mounting wall 100, particularly from the receiving opening 101, is thus made more difficult or even completely prevented. If necessary or desired, the electronic display device 120 can be manually detached from the mounting wall 100.

[0056] To reinforce the attachment of the electronic display device to the mounting wall, the fastening element 110 is also provided. The fastening element 110 is designed for the detachable attachment of the electronic display device 120 to the mounting wall 100. The fastening element 110 is provided on a contact area 102 of the mounting wall 100, against which a corresponding fastening section 123 of the base body 121 of the electronic display device 120 is placed. The fastening element is shown in Fig. 1.

[0057] 110, for example, is provided at a contact area 102 or at a fastening section 123 of the base body 121 in the receiving opening 101.

[0058] In particular, the fastening element 110 has a first connecting component 111 and a corresponding second connecting component 112, wherein the first connecting component

[0059] The first connecting component 111 is located on the mounting section 123 of the electronic display device 120, and the second connecting component 112 is located on the contact area 102 of the mounting wall 100. The first connecting component 111 and the corresponding second connecting component 112 are components of a hook-and-loop fastener system, wherein the first connecting component 111, in particular a loop or felt strip element, is arranged on the mounting section 123, and the second connecting component 112, in particular a hook strip element, is arranged on the contact area 102 of the mounting wall 100. This provides a hook-and-loop fastener system that can be opened and closed almost any number of times. The size of the receiving opening 101 is further dimensioned to receive the base body 121 or base frame, or a functional section of the base body 121, which includes a functional device 124, such as a battery, or the battery cover.In this case, the edge of the screen 122 that extends beyond the functional section can be in contact with the front or surface 103 of the mounting wall 100.

[0060] The receiving opening 101 in the embodiment shown in Fig. 1 is designed as a blind hole in the mounting wall 100. Accordingly, for example, a predetermined seat or a predetermined positioning at a specific depth in the receiving opening 101 for the electronic display device 120 can be defined.

[0061] Fig. 2 shows a schematic top view of a mounting wall 100 with a plurality of receiving openings 101, wherein corresponding electronic display devices 120 are attached to some of the receiving openings 101. The mounting wall 100 can, for example, have a round, oval, or polygonal, for example rectangular, outline.

[0062] The receiving openings 101 can be arranged in a specific pattern along rows and columns so that one or a plurality of electronic display devices 120 can be received and attached to any receiving openings 101.

[0063] In particular, the contour of the receiving opening 101 can be adapted to a corresponding contour of a receiving area of ​​the electronic display device 120 such that an interference fit (for example, a clearance fit, transition fit) is provided, and thus an interference connection exists in the receiving opening 101 between the mounting wall 100 and the receiving area of ​​the electronic display device 120. The receiving area of ​​the electronic display device 120 defines the area or its outline that is present in the receiving opening when the display device 120 is attached to the mounting wall 100.

[0064] The receiving opening 101 is adapted to the contour of the base body 121 such that the base body 121 can be received in the receiving opening 101 in a non-displaceable manner, and in particular, in a rotationally fixed manner. Furthermore, due to a predetermined contour / outline of the receiving opening 101 (for example, oval or polygonal) and a corresponding contour of the receiving area of ​​the electronic display device 120, a desired alignment of the electronic display device 120 can be achieved in the receiving opening 101.

[0065] The shape of the receiving openings 101, in this case round, square, and hexagonal, is adapted to the shape of the electronic display devices 120 to be received, specifically the designated body section of the electronic display devices 120. This allows even the positions of groups of electronic display devices on the mounting wall 100 to be defined, reliably preventing accidental incorrect positioning of the respective electronic display device outside its group. For example, in the first column shown in Figure 2, display devices 120 with a base body 120 can be received with a round, circular contour; in the middle second column, display devices 120 with a base body 121 with a rectangular contour; and in the right third column, display devices 120 with a base body 121 with a hexagonal contour.

[0066] Fig. 3 shows a schematic representation of a system 150 comprising a mounting wall 100 with a receiving opening 101, wherein the receiving opening 101 is provided as a blind hole and the screen 122 protrudes from the receiving opening 101.

[0067] The contact area 102 is formed on a surface of the mounting wall 100, which surrounds the receiving opening 101 and on which the base body 121 of the display device 120 can be placed. Similarly, the mounting section 123 of the electronic display device 120 can be placed on a surface of the mounting wall 100 surrounding the receiving opening 101, and the contact area 102 with the mounting element 110 is formed on the surrounding surface 103.

[0068] The contact area 102 is therefore not located within the receiving opening 101, but outside the receiving opening 101 on a surface 103 that surrounds the receiving opening 101. The base body 121 of the electronic display device 120 is T-shaped or mushroom-shaped, with the screen 122 being formed in the area with the larger diameter and the narrow area being located within the receiving opening 101.

[0069] In addition to the contact area 102 described above outside the receiving opening 101, a further contact area can be provided inside the receiving opening 101, so that several contact areas 102 can be attached to corresponding mounting sections 123 of the electronic display device 120. Accordingly, several identical or different mounting elements 110 can be provided between the corresponding mounting sections 123 and the contact areas 102.

[0070] Fig. 4 shows a schematic representation of a system 150 comprising a mounting wall 100 with a receiving opening 101, wherein the receiving opening 101 is designed as a through-hole and the screen 122 protrudes from the receiving opening 101. Thus, a variety of differently designed electronic display devices 120, with different depths, can be received in a receiving opening 101 without, for example, an insufficient hole depth in a blind hole causing the electronic display device 120 to protrude. The through-hole is closed with a contact element 401 of the mounting wall 100, wherein the contact element 401 has the contact area 102 with the mounting element 110 of the electronic display device 120.The contact element 401 can, for example, be a film-like element attached to a rear surface of the mounting wall 100 and sealing the receiving opening 101. The contact element 401 can, for example, be an adhesive film and thus simultaneously a part of the mounting element 110. When the mounting section 123 of the electronic display device 120 comes into contact with the contact area 102 on the adhesive film, which acts as the contact element 401, a corresponding fastening can be achieved.

[0071] The thickness of the mounting wall 100 is determined by the base body 121 to be mounted on the corresponding electronic display devices.

[0072] 120 adapted so that contact is made between the mounting section 123 and the contact area of ​​the contact element 401. Furthermore, the contact element 401 can have an adapter element that projects from the rear side of the mounting wall 100 into the receiving opening 101 to provide contact between the mounting section 123 and the adapter element of the contact element 401 if the thickness of the mounting wall 100 is greater than the penetration depth of the base body.

[0073] 121 into the receiving opening 101.

[0074] Fig. 5 shows a schematic representation of a system 150 comprising a mounting wall 100 with a receiving opening 101, wherein the receiving opening 101 is provided as a blind hole and the screen 122 is flush with a surface 103 of the mounting wall 100.

[0075] The contact area is formed at the bottom of the blind hole. The mounting section 123 of the electronic display device 120 is arranged such that, when the electronic display device 120 is positioned in the receiving opening 101, the mounting element 110 between the mounting section 123 and the contact area 102 enables fixation.
