Description

[Technical Field]

[0001] The present invention relates to a support device, in particular a rack rail, for supporting electronic equipment, preferably an electronic display unit, which supports a storage area for accommodating electronic equipment. classification It is equipped with a boundary wall. [Background technology]

[0002] Patent document 1 discloses a support device in the form of a rack rail configured to mechanically fix an electronic device realized as an electronic display unit. The rack rail defines the boundaries of a storage area for accommodating the display unit by three side walls arranged in a U-shape, i.e., the storage area is bounded from three sides by classification The display unit can be inserted into or removed from the rack rail through the open side of the U-shape.

[0003] The central first side wall is formed by a plate. The plate serves as a reference or mounting surface that allows the display unit to be mounted on the rack rails using the rear wall of the display unit. The plate has sockets arranged in a grid pattern. These sockets serve to connect the contact pins of the display unit to electrical conductor paths to supply power to the display unit. These conductor paths are arranged on the first side wall, opposite the storage area.

[0004] Viewed in the longitudinal direction of the rack rail, the first side wall is bounded by an upper second side wall and a lower third side wall.

[0005] The lower side wall has a fixing edge extending in the longitudinal direction of the rack rail, which edge can be surrounded by a fixing slit of the display device.

[0006] The upper side wall has hole-like cavities arranged in a grid pattern along the length of the rack rail, and these cavities can be engaged with the removable fixing pins of the display device, thereby fixing the position of the display device along the rack rail.

[0007] The rack rail has proven to be superior in operation because it allows for precise placement of the display device along the rack rail based on a pattern of hole-like cavities, and the second and third side walls, combined with pins that are pulled out and engaged in the upper side walls, make unintentional displacement of the display device from the rack rail, or even unintentional or intentional removal, as much as possible without the application of destructive forces.

[0008] However, the care of the rack rails has proven to be problematic, since dirt can accumulate both in the grooves formed by the lower side walls between the center plate and the fixing edges, and in the outlets in the center plate leading to the wireways, which, on the one hand, can negatively affect the optical appearance of the rack rails, and, on the other hand, can impair the power supply of the display unit and therefore its functional reliability.

[0009] [Patent Document 1] International Patent Publication No. 2017 / 153481 Summary of the Invention [Problem to be solved by the invention]

[0010] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an improved support device and correspondingly adapted electronics for this device, so as to avoid the problems discussed above. [Means for solving the problem]

[0011] This problem is solved by a support device according to claim 1. The subject of the invention is therefore a support device for mechanically fixing electronic devices, preferably embodied as a rack rail, particularly preferably for fixing electronic display units, comprising a first delimiting wall, in particular a reference wall defining a reference or installation surface, on which or adjacent to which the display device can be installed, in particular by means of its rear wall, on the support device, and a second delimiting wall oriented at an angle to the first delimiting wall, in which the first and second delimiting walls delimit, in particular on only two sides, a storage area for accommodating the electronic device. classification The support device is provided with a second boundary wall for supporting the first boundary wall and a wiring support 5 for supporting a wiring path for supplying power to the equipment, characterized in that the wiring support extends into the storage area at a distance from the first boundary wall, starting from the second boundary wall, and in particular parallel to the first boundary wall.

[0012] Furthermore, this problem is solved by a supply device as defined in claim 16. The subject of the present invention is therefore a supply device, in particular for a support device embodied as a rack rail, for supplying power to electronic devices that can be supported by this support device, particularly preferably to an electronic display unit, which supply device is designed to be connectable to a side section or end section of the support device, which side section or end section is designed or arranged to accommodate the supply device, and which comprises a power supply circuit and contacts that establish an electrically conductive connection with the wire tracks arranged on a wire support of the support device and are connected to the power supply circuit, wherein the contacts are realized by a first group of metallic contact belts, each contact belt having a first section, preferably a first end section, and a second section, preferably a second end section, the first section being connected to the power supply circuit and the second section being intended to come into contact with the wire tracks of the wire support, and each contact belt having a curved or bent shape, preferably at least L-shaped, particularly preferably C-shaped or U-shaped.

[0013] Furthermore, this problem is solved by an electronic device according to claim 19. The subject of the invention is therefore an electronic device, in particular an electronic display unit, having a housing with a rear wall, a front wall, in particular having a screen, and side walls extending between the rear and front walls, the side walls having cable support slots extending approximately parallel to the rear wall and designed to accommodate cable supports of a support device, the cable supports comprising wiring paths for supplying power to the electronic device, in particular the display unit.

[0014] Furthermore, this problem is solved by a system according to claim 29. The subject of the invention is therefore a system comprising a support device according to the invention, a supply device according to the invention connected to this device, and at least one electronic device according to the invention supported by the support device.

[0015] The measure according to the invention has the advantage that the installation of the electronic device is significantly simplified. Due to the absence of a fixing edge on the lower side wall, as is the case with known rack rails, which is achieved by the measure according to the invention, the electronic device can be simply pushed into the support device without tilting. This means that the electronic device can be moved along the first delimiting wall, which in this case can also function as a reference wall, in such a way that it can be pushed towards the second delimiting wall, in particular without having to lift the electronic device to be pushed in from the first delimiting wall.

[0016] The same applies to removing electronic devices.

[0017] By eliminating the disadvantageous configuration of the prior art, i.e. by eliminating the fixing edge (below, when the rack rail is mounted horizontally) and therefore also the groove, a further advantage is achieved here: dirt in the form of solid or liquid substances can no longer accumulate, so that both the optical and functional impediments caused thereby are virtually eliminated.

[0018] Indeed, the area is surrounded by two boundary walls, or the boundary classification By transferring the wiring paths of the wiring support to the area within the receiving area, it is also ensured that there is little or no possibility of contamination of the wiring paths there. Significantly, the same is true for the wiring support slit of the electronic device, which is provided to receive the wiring support and where the contacts of the electronic device are located. This means that when the device is inserted into the support device, this wiring support slit is covered, i.e. protected, by the second demarcating wall of the support device.

[0019] This means that the measures according to the invention can significantly reduce the maintenance frequency of the support device, in particular the support device realized as a rack rail, or of the entire system: since the danger points in terms of contamination are eliminated in the configuration according to the invention or are arranged and configured here in such a way that the risk of contamination is minimized as much as possible, cleaning is easier and has to be done less frequently.

[0020] In the most advantageous case, the wiring support is oriented parallel to the first boundary wall. However, other orientations are also possible. For example, the wiring support can be oriented in a direction such that, as viewed from the second boundary wall, the distance from the first boundary wall continuously increases. The wiring support is then oriented in the receiving area in a direction slightly inclined forward relative to the open side of the receiving area. In this case, the orientation of the wiring support slit relative to the rear wall of the electronic device can be adapted accordingly, so that the electronic device can be inserted into the receiving area by sliding along the wiring support toward the first boundary wall.

[0021] Furthermore, the rear side of the first demarcation wall does not necessarily have to extend parallel to the front side of the first demarcation wall. Rather, it can be defined that the front and rear sides of the first demarcation wall overlap and taper in a wedge-like manner toward the second demarcation wall relative to the viewing direction. Therefore, the cross section of the first demarcation wall can also be realized in a roughly wedge-like shape. That is, a distinction can be made between the rear side of the demarcation wall and the front side (e.g., referred to as the reference side) of the demarcation wall, which is inclined relative to the rear side. Even in this case, as already mentioned, the orientation of can be parallel to the front side of the demarcation wall or inclined at a slight angle thereto. In the latter case, the orientation of the wiring support slit can be adapted accordingly, as previously described.

[0022] Similarly, rather than adapting the orientation of the wiring support slit, it is also possible to keep this orientation approximately parallel to the front side of the electronic device, or to extend centrally between the front and rear sides of the electronic device, and adapt the orientation of the rear wall of the electronic device so that the electronic device inserted into the support device fits in an approximately form-fitting shape.

[0023] For example, in a rack rail that extends horizontally, the electronic equipment can be accessed from the rear of the rack rail, which also makes overall handling easier.

[0024] Furthermore, the measures according to the invention have the advantage that the support device is more compact, which in turn increases the field of view of the objects, in particular the products, located below it. Thus, for example, in a support device according to the invention embodied as a rack rail, a customer can easily see the products on the shelves below the rack rail without being obstructed by structural parts that protrude downward from the rack rail.

[0025] Generally, these measures according to the invention allow a freer and easier view of the system, in particular of the support device and the electronic devices fixed to this device, in particular the electronic display unit, and thereby allow a better display of the goods.

[0026] The measures according to the present invention and the resulting omission of the lower fixing edge further enable the use of electronic devices that can have extensions parallel to the first demarcation wall (reference wall) that are only slightly larger, or even significantly larger, than the extension of the first demarcation wall. Therefore, such rack rails can be made thinner than the display unit, which automatically draws attention to the display unit without the rack rail being perceived as a large, optically obstructive component. In other words, the omission of the lower fixing edge allows the use of electronic devices with almost any dimension parallel to the first demarcation wall or reference wall. This allows almost any electronic device to be adapted for use with such a support device. In particular, electronic display units with very specific and very different screen sizes can be inserted, as well as large-screen electronic interaction media, such as touchscreens. To an observer, these devices appear to be suspended within the support device, for example, because their lower sides are above the support device.

[0027] The support device can be realized in various ways in principle. For example, it can be a table stand that can be placed on a counter or fixed thereto. Likewise, the support structure can be configured as a clothes hanger on which clothes can be hung and fixed thereto. However, for reasons of compactness in describing the invention, in the following, only rack rails will be referred to as an advantageous configuration of the support device.

[0028] The orientation of the support device, and therefore the orientation of the device fixed thereto, can also be set arbitrarily.

[0029] The current-carrying connection between these supply devices and the supporting device can be realized, depending on the conditions, in a releasable or non-releasable manner, ie in particular in the form of a material bond, for example by a solder connection.

[0030] It is often advantageous if this current connection can be easily releasable again, which can be achieved in particular by means of a releasable connection such as a connector connection or a screw plug.

[0031] Advantageously, this current-carrying connection is realized as a releasable connection with a spring element, which ensures that the electrical contact remains established with minimal force even if the position of the components to be connected varies within a certain range, which may be caused, for example, by manufacturing tolerances, thermal expansion, deformation due to friction, incorrect assembly of components or mechanical loading of the system components.

[0032] Advantageously, the supply device comprises a first group of metallic contact belts, i.e. conductive metallic contact belts, which are adapted to provide an electrical connection with the support device or with the wiring tracks of the support device.

[0033] These contact belts can be configured to provide non-releasable or releasable contacts, for example contacts in the form of material bonds.

[0034] In the embodiment with connector-connected contacts, these contact belts are realized in such a way that when the supply device is pushed into the support device, the contact belts approach the raceway, and for this purpose the periphery of the raceway is configured in such a way that the contact belts are prevented from slipping away from the raceway. Due to the local deformation in the flexible area, a reliable contact is obtained.

[0035] To achieve a non-releasable contact, in particular a contact in the form of a material bond, the contact belt can be realized so that it comes into contact with the wiring path when pressed into the support device, after which the contact belt can be soldered, for example.

[0036] However, preferably, a spring-based releasable connection is used, i.e., a connection by means of a spring element, in which the contact belt is pressed against the wireway by a spring force when the supply device is pressed into the support device. In contrast to a connector connection, the force ensuring the contact is not generated by deformation at the contact point or only locally, but rather, for example, by deformation, for example by bending, at points other than the contact point or along the contact belt.

[0037] Particularly advantageously, the contact belt itself constitutes the spring element, i.e. the contact belt is realized as a supply spring contact element.

[0038] As previously mentioned, these contact belts have a first section, preferably a first end section, connected to the power supply circuit, and further have a second section, preferably a second end section, configured to provide an electrical connection or contact.

[0039] These contact belts can be configured in various shapes or with various arrangements of the first and second sections.

[0040] Thus, in one simple configuration, the contact belt can be bar-shaped, so that the first and second sections lie in a plane roughly along the surface of the bar.

[0041] It is also possible to arrange these two sections slightly offset but generally parallel to one another, ie in one or more stages or in a Z-shape.

[0042] It is also possible to place the two sections at an angle relative to each other, resulting in an L-shape or a V-shape.

[0043] It is also possible to have two sections generally parallel to each other, but with multiple sections bent between them, resulting in a C-, U- or W-shape.

[0044] In addition to the above-described embodiment, other multi-tiered configurations of the sections are also possible, resulting, for example, in a thunderbolt-shaped contact belt.

[0045] These folded multi-stage embodiments have the advantage that they require less material and at the same time allow for a larger spring deflection, which can also be achieved with a curved shape of the metal contact belt.

[0046] Furthermore, the belt shape of the contact belt allows the contact belt to easily overcome or has a shape that overcomes the level difference between the plane of the electronic circuit to which the contact belt is connected and the plane of the wiring path to be contacted, thereby achieving contact with a predetermined minimum force (i.e., the maximum force within the range of forces that would otherwise occur) that can be set or defined by the shape and elasticity of the material of the contact belt.

[0047] Advantageously, steel belts are used which are corrosion resistant.

[0048] That is to say, despite the mobility of the contact surfaces or contact zones, complex, in particular individual mechanical parts which move relative to one another, are dispensed with.

[0049] Further particularly advantageous embodiments and refinements of the invention emerge from the dependent claims and the following description.

[0050] Finally, countless examples of electronic devices include sensor units or sensors such as motion sensors, temperature sensors, light sensors and cameras; input devices such as buttons, contact sensors and touch screens; output devices such as illuminators, speakers and printing machines, e.g., thermal printers; or electronic display units implemented using, for example, liquid crystal display (LCD) screens, organic light emitting diode (OLED) screens, e-paper displays or electrophoretic displays.

[0051] The supply device supplies the electronic device with the supply voltages required for its operation as well as for communication purposes. This means that in addition to the power supply (supply voltage and current), it also provides data- or signal-technical supplies for the purpose of transmitting information and driving the electronic device. For power supply purposes, the supply device can be powered by a network device, a (rechargeable) battery system, or "power over WiFi." In the case of batteries (also rechargeable batteries) or accumulators, the energy storage device can be advantageously fixed in the immediate vicinity of the supply device using magnets on the support device or adjacent components, allowing for quick and uncomplicated replacement. The support device can also be equipped with a photovoltaic module, which is used to store energy for charging rechargeable batteries.

[0052] The supplying device or its power supply circuitry may further be configured to process or edit data, i.e., to receive data from a server via an access point and convert the data into signals or data that can be read or processed by the electronic device, or simply forward it as raw data to the associated (addressed) device only. Data may also be received from the device and output to the server via the access point. Transmission between these access points and the supplying device may be by wired connection or wirelessly.

[0053] The supply device may be located independently of the support device or may be fixed to the rear of the support device or to one side of the support device and be electrically connected to the wireways of the wire support of the support device.

[0054] In this context, it has proven particularly advantageous for the support device to comprise a lateral compartment configured or arranged to accommodate supply equipment for the purpose of supplying power to electronic equipment that can be supported by the support device.

[0055] Advantageously, the supply device is correspondingly adapted to be accommodated in a lateral compartment of the support device.

[0056] This allows for a very compact system to be achieved, while at the same time the supply equipment is accommodated within the structure of the support device in a manner that is protected against environmental influences, such as moisture and mechanical loads.

[0057] Loose cabling between the supply equipment and the support equipment cannot be seen or manipulated.

[0058] It is advantageous to completely integrate the separate supply device with the rail, in which case, for example, the housing of the supply device also matches the shape of the support device, so that the two together give the impression of being made up of a single casting.

[0059] Furthermore, it has proven advantageous for each contact belt to have, in its second section, an arch shape defined so as to come into direct contact with one of the raceways.

[0060] This arch shape prevents the second section of the contact belt from digging into or catching on the support device when inserting the supply equipment, which could cause damage to the component, e.g., the contact belt, or otherwise deforming the wireway, during careless or hasty insertion. Thus, this arch shape allows for faster and more efficient assembly and maintenance of the system without the aforementioned risks.

[0061] The shape also provides improved contact since the radius of curvature of such an arched shape provides a defined contact surface or contact zone along the metal belt.

[0062] To optimize contact between the raceway and the contact belt, the arched shape of the second section can have a contact area that matches the shape of the raceway. Thus, if the raceway has a circular cross section, the arched surface can have, for example, semicircular notches or grooves that correspond to the raceway, thereby enlarging the contact surface or zone along the curvature of the raceway.

[0063] In another aspect, the supply device comprises a housing portion that is open on at least one side, so that the wiring support can be inserted into the open housing side, and the housing portion is shaped to enclose the second section of the contact belt and the portion of the wiring path that can contact it, i.e., that portion of the wiring support.

[0064] This embodiment provides protection for the embedded contact belts and wiring tracks, in particular protection against contact, moisture, mechanical loads, temperature loads and undesirable views, i.e. visual protection, of the components.

[0065] Furthermore, the housing part ensures a predetermined position of the contact belt relative to the raceway, for which purpose the housing has compartments or surfaces that cooperate with a support device to accordingly place or hold the housing part thereon.

[0066] This housing portion provides stability to the delivery device while also providing structure to hold all of the delivery device components in their desired positions.

[0067] This housing part can also be configured to cover or house part of the wire support, which in the assembled state makes it even more difficult to perform unauthorized manipulation of the system's electronic components. When the housing also comes into contact with the wire support, this measure ensures that the metal contact belt presses against the wire path with a force caused by its own spring action, thus ensuring mechanical stability wherever it presses against the wire support.

[0068] The wire support of the support device can be realized in one piece or in a multi-piece form, in both cases the wireways can be placed in one or more planes, with the contact belts of the supplying device correspondingly configured or arranged to come into contact with the wireways.

[0069] However, it has proven particularly advantageous to configure the wiring carrier of the carrier device as a wiring carrier plate.

[0070] This is a very space-saving, narrow and at the same time stable implementation, which allows sufficient space for the wiring tracks. The wiring tracks can be arranged on one side or on different sides of the board. This board offers the advantage in particular that the wiring tracks can run along the board, for example in one plane, with sufficient spacing from one another.

[0071] The use of this wiring carrier plate provides the electronic device with defined contact points or contact zones at which the wiring carrier or wiring carrier plate comes into contact with the electronic device when the system is used as intended, in particular so that when the device is fully inserted into the wiring carrier slot, the position of the device is precisely defined, and this occurs in a particularly reliable manner so as to ensure electronic contact.

[0072] In another aspect, the wiring support plate has a first dimension measured along the longitudinal extension of the support device and a second dimension measured in the plane of the wiring support plate at a right angle to the first dimension of the wiring support plate, the second dimension of the wiring support plate being equal to 20% to 40% of the corresponding dimension of the first demarcation wall.

[0073] This achieves that the wiring carrier board is realized to be sufficiently stable and rigid, while at the same time ensuring sufficient spacing between the wiring tracks.

[0074] Furthermore, these dimensional ratios allow for easy removal of electronic equipment from the support device and easy insertion or installation of electronic equipment into the support device, since the dimensions of the wiring support plate ensure spatial guidance for the movement of the equipment when it is pushed into or pulled out of the support device.

[0075] These dimensions, using conventional materials and material strengths, provide sufficient stability and robustness to reliably prevent the wiring support plate from failing against the first demarcation wall, thereby also ensuring that the electronic device can be slid or shifted along the support device without being clamped.

[0076] Advantageously, this first dimension extends over the entire length of the support device, so as to allow the equipment to be supplied over its entire length.

[0077] The wiring support can have several wiring tracks for the signal-technical supply and several, in particular two, wiring tracks for the power supply, so that, for example, one pair of wiring tracks serves to supply power, and another, for example ten wiring tracks, implements a data bus for the parallel transmission of information in both directions.

[0078] However, advantageously, the wiring support comprises exactly three pieces of wiring paths which are advantageously arranged on a single lateral surface of the wiring support or which run parallel to one another along the longitudinal extension of the support device, or both.

[0079] This embodiment allows for both the signal-technical supply and the power supply to be carried out using as few components as possible, in particular contact components such as contact belts, and therefore allows for a compact and space-saving implementation.

[0080] These fewer components also make the implementation less vulnerable to malfunctions, which in turn improves operational safety and therefore reduces the overall maintenance burden, which also results in cheaper manufacturing.

[0081] This implementation of a wiring support consisting of exactly three pieces of wiring paths can be realized by using the same reference potential for one of these wiring paths, the signal supply wiring or data supply wiring, and another wiring path, the power supply wiring, where a third wiring path, also called the reference potential wiring, has this reference potential.

[0082] Particularly advantageously, these wiring paths are arranged in such a way that, relative to the direction of insertion of the electronic device, the ground wiring is arranged as the first wiring path, followed by the signal or data supply wiring, and finally the power supply wiring, so that a current circuit between the power supply wiring and the ground wiring is only obtained when the electronic device is fully inserted, which prevents short circuits and damage to the electronic components.

[0083] The raceways of these support devices can have a variety of shapes or cross sections.

[0084] In one embodiment, these wiring paths can be flat or have a rectangular cross section, which has the advantage that a larger cross section of the wiring is ensured at the contact point when the spring-based connection is made. Flat wiring paths can be easily realized as tracks on a carrier plate, as in the case of a printed circuit board, for example.

[0085] However, in one advantageous embodiment, these wiring paths are realized as electrical wires that partially protrude beyond the outer surface of the wiring support.

[0086] Besides these manufacturing advantages, this embodiment offers advantages with regard to electrical contact with electronic equipment.

[0087] This is particularly advantageous when the electronic device, in particular the electronic display unit, is provided with contacts that establish an electrical connection with the wiring paths of the wiring support based on one advantageous embodiment, in which each housing portion forming the wiring support slit has a first housing opening through which the contacts protrude from the housing.

[0088] The wiring support slit allows the electronic device and its contacts to be installed in a clearly defined position relative to the wiring path, so that when the device is fixed to the support device, i.e. when the wiring support is installed in its target position in the wiring support slit, these contacts will automatically and reliably make an electrical connection with the wiring path without further adjustment.

[0089] The wires as raceways have a generally rounded cross section that protrudes beyond the surface of the wire support, rather than a flat cross section that terminates generally flush with the surface of the wire support. This cross section allows a tactile response when one of the contacts on the electronic device makes contact with one of the wires as the electronic device is inserted. In this way, the user can easily determine whether each contact of the device has already reached or passed through the wire support.

[0090] Wires as raceways are also attractive due to their robustness compared to, for example, planar raceways.

[0091] Advantageously, the wires are embedded in the wire support over at least 50% of their cross section. In this embodiment, the wire support surrounds each wire by at least a little more than 180°, ensuring a secure hold within the wire support, i.e., reliably preventing the wires from unintentionally rolling out of the wire support.

[0092] The raceways may be disposed on the wiring support such that they are located on each side of the wiring support opposite the first demarcating or reference wall.

[0093] Advantageously, however, the support device is configured so that a raceway is arranged on each side of the wire support facing towards the first delimiting or reference wall.

[0094] The electronic device is therefore advantageously configured in such a way that the first housing opening is realized on the side of the wire support slit closest to the rear wall.

[0095] These advantageous implementation measures provide the advantage that the wiring paths are only barely visible or are completely invisible, in particular that accidental or intentional contact with conductive objects is virtually eliminated. As a result, the risk of short circuits or transmission disturbances is also reduced or completely eliminated. The arrangement in which the wiring paths extend largely hidden from the view of an observer of the support device (e.g., rack rail) provides in any case extensive protection from dirt, so that the maintenance burden thereon is negligible.

[0096] In another aspect, this electronic device is configured so that when the wiring support is inserted into the wiring support slit as specified, each of the housing openings corresponds to exactly one position in the wiring path.

[0097] This ensures that when the device is combined with a support device, a precisely defined contact zone always results, which precisely contacts the wireway in its final or target position, so that when the electronic device is fully inserted into the support device, a correct electrical connection is necessarily obtained without the need for subsequent adjustment or correction of the relative positions of the two objects.

[0098] In another aspect, the contacts of the electronic device are realized as a second group of metallic contact belts, each contact belt having a first section (this first section is connected to the electronic circuit of the device), advantageously a first end section, and a second section (this second section is designed to contact the wiring path of the wiring support), advantageously a second end section, and the second group of metallic contact belts are realized as spring elements, and advantageously each contact belt is configured in a curved or bent shape, in particular in a stepped shape.

[0099] This allows for a pressure contact, so that the advantages mentioned in the context of the first group of metallic contact belts when they are implemented as spring-connected connections are also valid in this case, so that, for example, angular errors and misalignments of the contact surfaces can also be leveled out.

[0100] Contacts known from the prior art, in which a coil spring presses a pin-shaped contact against an opposing contact in a linear motion, have proven to be disadvantageous not only because of their large number of components but also because they quickly cease to function, especially when soiled.

[0101] By realizing the second group of metallic contact belts as a (roughly one-piece) spring element, the drawbacks of telescopic-based spring contacts are overcome: dirt particles, such as grain or dust, or otherwise sticky liquids, which may reach these known systems and cause malfunctions, do not have any adverse effect on the embodiment according to the invention.

[0102] In one advantageous embodiment, these contact belts are configured in a curved or bent shape, in particular in a stepped shape, which further improves the deflection of the spring, which further reduces the risk of digging in or pinching as a result of dirt or wear.

[0103] Furthermore, the strip-shaped configuration of the contact belt allows or enables it to easily overcome the level difference between the plane of the electronic circuit to which it is connected and the plane of the wiring path to be contacted, thereby achieving contact with a predetermined minimum force (maximum force within the range of forces that would otherwise be generated) that can be set or defined by the shape and elasticity of the material of the contact belt.

[0104] Advantageously, steel belts are used which are corrosion resistant.

[0105] That is to say, despite the mobility of the contact surfaces or contact zones, complex, in particular individual mechanical parts which move relative to one another, are dispensed with.

[0106] In one advantageous embodiment of this electronic device, in particular an electronic display unit, each contact belt of the second group has in its second section a raised shape provided for direct contact with one of the wiring paths, and at least this raised shape of the contact belt protrudes from the housing at the corresponding housing opening into the spatial area bounded by the wiring support slit.

[0107] The raised shape ensures that only a single raceway contacts each contact belt at approximately one point on the raised shape, while adjacent regions of the contact belt extend spaced apart from the raceway, i.e., without contacting the raceway.

[0108] Advantageously, the raised shape is rounded on the side that contacts the raceway in the assembled state.

[0109] This raised shape allows the electronic device to be pushed into the support device without digging in and with almost no friction. During the pushing, the second section of the contact belt first slides along the surface of the wire support until it reaches the wireway. Once there, the second section of the contact belt conforms to the cross-sectional shape of the wireway during further pushing without digging in or rubbing against the wireway.

[0110] This raised shape can be achieved, for example, by bending the contact belt at the point in question so that it has a curvature, for example, a raised shape. However, this raised shape can also be achieved, for example, by attaching additional material to the second section of the contact belt, which is otherwise straight. However, the desired shape can also be created by another deformation method, so that the plunger presses the shape of the handle against the second section, which is made of, for example, tinplate.

[0111] The shaping of the contact belt can be achieved in the same way for both the electronic device and the supply device.

[0112] The wiring support of this support device can be connected in a materially bonded manner to the second delimiting wall of the support device, so that, for example, these components can be welded or glued together.

[0113] The wiring support and the second demarcation wall may both be made from a single material, and as such may be, for example, a cast part.

[0114] Additionally, the wiring support and the second demarcation wall may be screwed or riveted together.

[0115] The wiring support can also be connected to the support device by means of a connector connection, in particular by means of a barbed connector connection.

[0116] However, it has proven particularly advantageous if the second demarcating wall of the support device has a receiving well adapted to receive the wiring support, in particular in a laterally slidable manner, and if the wiring support has a shape corresponding to the shape of the receiving well, in particular a T-shape or an inverted L-shape, etc., and is inserted into the receiving well. This allows for easy assembly of the wiring support with the support structure while at the same time providing good stability. The wiring support can also be easily removed in this way for maintenance or cleaning. The wiring support can also be replaced in a modular manner as a replacement part. In this way, for example, in the event of damage, it is not necessary to replace the entire support device.

[0117] In one alternative aspect, the second demarcating wall of the support device may comprise a support frame extending generally along the longitudinal extent of the wiring support and providing mechanical support thereto.

[0118] This support frame makes it possible to design the wiring support in a less stable manner, which on the one hand makes it possible to resort to cheaper materials and on the other hand makes it possible to achieve a narrower profile of the wiring support or otherwise to easily realize the wiring support in a material-saving manner.

[0119] This mechanical reinforcement also allows for longer variants of the support device. Furthermore, the support frame acts to prevent damage to the wire support during installation or operation. Protecting the wire support also provides improved protection for the wire belt, since the wire support is less likely to be caught or deformed due to the action of bending moments, as the case may be.

[0120] This support frame can be made, for example, from plastic or, advantageously, from metal.

[0121] In one embodiment, the support frame is configured to be received in a receiving well of the second demarcation wall beside the wiring support, the second demarcation wall being correspondingly configured to receive the wiring support and the support frame together, and the second demarcation wall being correspondingly configured to receive the wiring support and the support frame together, for example, the support frame can have a T-shape at a corresponding end that is inserted into the receiving well, and the wiring support can have an L-shape that is fixed in the receiving well on one side of the T-shape of the support frame.

[0122] Advantageously, the wiring support is made from plastic.

[0123] This allows for the implementation of wiring paths without additional insulating layers, in particular those realized as electrical wires. In this case, the wiring support itself is the insulator. Furthermore, it is cheaper to manufacture and lighter in weight. In this case, plastic should also be understood as a synonym for polymer, and therefore also includes natural polymeric substances. Furthermore, the wiring support can be made from fiber-reinforced plastic or hard paper.

[0124] The first demarcation wall or reference wall and the second demarcation wall may also be made from plastic.

[0125] These sections can be manufactured separately and connected together in the manner already described.

[0126] However, it has proven particularly advantageous to construct the first delimiting wall or reference wall and the second delimiting wall, in particular also the support frame, in one piece, in particular from steel.

[0127] In this way, an optimal stiffness of the support device can be achieved, which further results in well-defined contact points even under load, and in particular even with a relatively long longitudinal extension of the support device. In particular, if the support frame is also realized integrally with the first delimiting wall or reference wall and the second delimiting wall, the wiring support is stably supported over its entire length, thereby preventing damage and loss of contact points due to the wiring tracks.

[0128] This can be achieved particularly well if these components are manufactured from steel, in particular from bent, possibly welded, sheet metal, which not only provides sufficient stability but also allows for easy and inexpensive manufacture.

[0129] In most cases, the electronic device must be coupled to a support device to prevent it from being accidentally dropped or removed. This can be achieved, for example, by selecting the dimensions of the support device and the electronic device so that, when combined, they are connected to each other by a pressure clamp. To this end, for example, the wiring support and the first demarcation or reference wall can be dimensioned so that they apply pressure to the inserted electronic device, and this pressure frictionally holds the electronic device in the desired position.

[0130] However, in one advantageous embodiment, the first boundary wall or reference wall of the support device has notches arranged in a grid pattern along its longitudinal extension, in particular openings passing through the first boundary wall or reference wall, which notches or openings are designed to be connected to the fixing means of the electronic device in a pressure-tight and / or form-fitting manner.

[0131] Such a fastening means can be realized in such a way that the electronic device has a fastening housing opening at the rear wall and advantageously has a manually operable fastening mechanism comprising at least two movable fastening hooks or fastening lugs which in an unoperated state protrude through the fastening housing opening and which change their position upon operation of the fastening mechanism.

[0132] In this case, the notches can be significantly wider than the fixing hooks or fixing handles, which allows the electronic device to be placed steplessly within a wide area along the support device.

[0133] Advantageously, these notches are approximately the same width as the fixing hooks or fixing handles. This allows for precise placement of electronic devices along the support device at grid intervals. It also makes it easier to place multiple electronic devices at the same intervals along the support device. This eliminates the need to measure again to ensure that the devices are evenly spaced, making it possible to more quickly install, for example, electronic displays and other electronic devices in a rack.

[0134] Furthermore, the relatively fine grid allows for installation in small steps, i.e., provides a large degree of freedom in design similar to stepless variations, while at the same time allowing for precise installation without remeasurement while adhering to specified minimum spacings.

[0135] In particular, the relatively fine grid configuration extending over substantially the entire length of the support device ensures that equipment secured thereto cannot unintentionally slide along the support device.

[0136] Furthermore, it has proven particularly advantageous to determine the grid configuration or dimensions of these cutouts to match the dimensions or arrangement of the fixing hooks or fixing handles so that appliances of different widths (measured in the direction of the longitudinal extension of the supporting device) can be installed as closely as possible on the supporting device and the available equipment area can be optimally utilized there.

[0137] Advantageously, the fixing mechanism of the electronic device, in particular the electronic display unit, comprises a manually operable button which is connected to the fixing hook or the fixing handle, and particularly advantageously is configured integrally with the fixing hook or the fixing handle, and is freely accessible on the side walls opposite each of the longitudinal structural slits.

[0138] Such a button allows for easy operation and fast removal of the electronic device, thereby providing for fast and easy maintenance or adjustment of this device, where removal is possible in particular without special tools.

[0139] Depending on the implementation, actuation of this button can cause the securing hook or securing handle to fold into the electronic device, slide in the insertion direction, or both. In all cases, actuation of this button and the resulting movement of the securing hook or securing handle causes the electronic device to become removable from the support device.

[0140] The integral structure of the fixing means of this device is a combination of a fixing hook or a fixing handle and a button, and the fixing hook or the fixing handle directly engages with the notch.

[0141] Alternatively, the two-piece or multi-piece construction of the fixing means of the device can be realized in such a way that the rear housing wall is provided with fixing hooks or fixing handles arranged in a grid of cutouts (or at multiples of the grid intervals). In particular, this rear housing wall is constructed integrally with the fixing hooks or fixing handles (in particular in two pieces arranged at grid intervals or multiples of the grid intervals). In this case, said housing openings for fixing are formed by U-shaped gaps that delimit the fixing hooks or fixing handles that are constructed as a housing wall frame.

[0142] In the mechanically relaxed rest position, these fixing hooks or fixing handles penetrate into the recesses of the support device to such an extent that the equipment is held there. Advantageously, two fixing hooks or fixing handles are provided, one located on the left side of the rear housing wall and the other on the right side, with sufficient spacing relative to the center of the rear housing wall.

[0143] The button can have operating protrusions corresponding in number to the number of fixing hooks or fixing handles and located at their positions for the purpose of releasing the electronic device from the support device. These operating protrusions are shaped so that, when the button is operated, the fixing hooks or fixing handles are rotated toward the inside of the housing of the device, so that the device can be removed from the support device. When the button is released, the fixing hooks or fixing handles rotate back to their rest positions due to the elasticity of the housing material, the elasticity of the material of the fixing hooks or fixing handles, and the corresponding springs acting thereon.

[0144] To facilitate coordinated movement of the fixed hook or fixed handle and the operating protrusion, they may have tapered ends so that they can move together against each other along a substantially inclined surface, exerting forces on each other that cause movement of the fixed hook or fixed handle.

[0145] In one advantageous embodiment, the locking mechanism comprises a locking mechanism spring element that holds the button in the first position in the unactuated state.

[0146] In this case, the unoperated state means that the electronic device is installed in the support device according to the present invention, i.e., is not being installed or removed. With respect to the buttons, the unoperated state means that the button is not pressed.

[0147] The spring element of the fixing mechanism not only provides easy operation, but also ensures that a force sufficient to overcome the spring force, in addition to a frictional force component, is applied to the button in order to remove the device from the support device, thereby preventing the device from accidentally falling off the support device, for example, due to a lateral force acting on the housing, i.e., not on the button.

[0148] In one advantageous embodiment, the support device is configured such that, with respect to the side of the first boundary wall facing towards the storage area, an acute angle is formed between the first boundary wall (or reference wall or reference side) and the second boundary wall, in particular an angle in the range of 35° to 85°.

[0149] This acute angle ensures that when the electronic device is deployed into the support device by the securing mechanism, the device can no longer fall out of the support device in a forward or downward direction.

[0150] Advantageously, this second boundary wall has a peripheral area extending along its longitudinal extension, which, facing the receiving area, is advantageously configured in the shape of a handle or hook, particularly advantageously in the shape of a curve.

[0151] This means that the second demarcating wall has a peripheral region that, in intended use, supports forward against the edge of the electronic device that is closest to the second demarcating wall in its inserted state. In this context, "forward" means in the direction from the first demarcating wall toward the electronic device. That is, this peripheral region captures the electronic device at the front edge of the housing and holds it protectively there beneath the second demarcating wall.

[0152] This acute angle allows the device to be deployed in a manner that captures the outermost upper edge and holds the device there under the action of a fixed hook or handle against the first delimiting wall.

[0153] Additionally, the peripheral area surrounding the equipment provides protection against objects stored on the rack or inserted or removed through the leading edge of the rack.

[0154] That is, the angles and dimensions of the second demarcating wall are advantageously selected or adjusted to one another so that the electronic device can reliably contact the peripheral area of ​​the support device with its front wall and thus maintain its position.

[0155] The second demarcation wall does not necessarily extend as linearly as possible or have a constant cross section. In embodiments where the transition of the shape of the second demarcation wall is complex, this angle can be understood as the angle between the plane in which the first demarcation wall extends and the plane between the intersection line of the first and second demarcation walls and the peripheral area of ​​the second demarcation wall.

[0156] Another aspect of the invention relates to the correct orientation of an electronic device when inserted into the support device. To ensure this, it has proven advantageous for the first demarcation wall of the support device, in particular in the area covered by the wiring support, to have a structure of demarcation wall ridges and intervening demarcation wall canyons arranged to cooperate with the structure of the housing ridges and intervening demarcation wall canyons of the housing of the device in order to create a target orientation of the electronic device when correctly inserted into the support device. The electronic device also has a structure of housing ridges and intervening demarcation wall canyons arranged to cooperate with the structure of the demarcation wall ridges and intervening demarcation wall canyons of the first demarcation wall in order to create said target orientation of the electronic device when correctly inserted into the support device.

[0157] For the purposes of the invention, these structures extend linearly and extend, on the one hand, at right angles to the longitudinal extension of the support device or, on the other hand, at right angles to the extension of the wire support slit.

[0158] These matching structures serve to create a desired orientation of the electronic device relative to the support device when the electronic device is properly inserted into the support device, thereby reliably preventing accidental contact of the wire tracks, which could potentially cause malfunctions or even short circuits between the wire tracks.

[0159] The length of these structures defines the position along the insertion movement until the target orientation is created. Since the wiring paths extend along the wiring support, it has proven particularly advantageous for the length of these structures to also be oriented along a direction perpendicular to the longitudinal extension of the wiring support, in the direction of the dimension of the wiring support measured parallel to the plane of the first demarcation wall. This should be defined as the minimum extent to create the target orientation already when the electronic device approaches the wiring support, or only when the electronic device first contacts the wiring support.

[0160] The width of these structures is advantageously approximately equal to the grid spacing of the notches along the longitudinal extension of the support device.

[0161] Finally, it should be noted that in one advantageous embodiment, both the notches and the intervening material frames of the support device have the same width, which is exactly equal to the lattice spacing, resulting in a periodic sequence of voids and material frames along the longitudinal extension of the support device.

[0162] That is, the support device as a whole can be implemented more compactly, resulting in a smaller field of view being covered in front of the product or the bottom of the rack. Such a smaller profile not only makes the system appear more valuable, but also allows for better visibility of items behind the support device.

[0163] These and other aspects of the present invention will become apparent from the drawings discussed below.

[0164] The invention will now be explained in more detail again by way of example with reference to the accompanying drawings, in which the invention is not limited to these examples, in which the same components are provided with the same reference numerals in the different figures.

[0166] Figure 1 shows a support device realized as a rack rail 1 and an equipment that fits onto this rack rail 1, realized for example as an electronic display unit 20, viewed from the side, with the rack rail 1 being viewed in cross section along a section adjacent to the display unit.

[0167] This rack rail 1 has a first demarcation wall 2 (reference wall 2) which is shown vertically in the drawing.

[0168] This first delimiting or reference wall 2 merges at its upper end into a second delimiting wall 3. In this embodiment, the second delimiting wall 3 and the reference wall 2 are manufactured integrally from steel.

[0169] Between the reference wall 2 and the second boundary wall 3, the boundaries on both sides are defined by these walls 2 and 3. classification There is a storage area 4 for storing a display unit 20 .

[0170] On the side of the display unit 20, i.e. measured within the spatial area of ​​the receiving area 4, an acute angle 8 of approximately 53° is formed between the reference wall 2 and the second delimiting wall 3.

[0171] The second demarcation wall 3 has a receiving well 7 into which a wiring support 5, realized as a wiring support plate, is inserted. The side of the wiring support 5 inserted into the receiving well 7 is adapted to the shape of the receiving well 7, i.e. is formed approximately in a T-shape. The wiring support 5 can be removed or pushed into the receiving well 7 in a direction perpendicular to the drawing plane of FIG. 1, so that the wiring support can be inserted or otherwise removed therefrom.

[0172] The wiring support 5 supports three wiring paths 6. Each of these wiring paths 6 is made from a solid copper wire 6 and is realized without an insulating layer. More than 50% of the cross section of these wires 6 and approximately two-thirds of their radial dimension are embedded in the wiring support 5. In this case, the wire 6 closest to the second demarcation wall 3 is the power supply wiring, the central wiring path 6 is the signal supply wiring, and the wiring path 6 farthest from the second demarcation wall 3 is the reference potential wiring. These wires 6 are arranged on the side of the wiring support 5 facing the reference wall 2.

[0173] The wiring support 5 and the reference wall 2 each have a first dimension (longitudinal extension) representing the extent of their length measured away from or towards the plane of the drawing, and in this embodiment both are the same size, e.g., about 1.5 m in length, although other lengths can also be defined for the rack rail 1.

[0174] The wiring support 5 has a second dimension (height) 9 that represents the vertical extent of the wiring support 5 in Figure 1. Correspondingly, the reference wall 2 has a third dimension (height) 10 that represents the vertical extent of the reference wall 2 in Figure 1. In this embodiment, the second dimension 9 of the wiring support 5 is about 40% of the third dimension 10 of the reference wall 2. In this embodiment, the second dimension 9 is, for example, about 3 cm.

[0175] In this embodiment, the wiring support 5 is manufactured from insulating polypropylene using an injection molding method, and the electric wires 6 are already embedded during the manufacturing process of the wiring support 5 .

[0176] In this case, the wiring support 5 is arranged free-standing. In contrast, Figures 7 and 8 show an embodiment with a support frame 11. In Figure 7, the support frame 11 is connected to the second demarcation wall 3 in a materially bonded manner, so that the reference wall 2, the second demarcation wall 3 and the support frame 11 together form one component, i.e., they are configured as a single piece. In Figure 8, the support frame 11 is realized as an independent part and is configured to be received or pressed into the receiving well 7 together with the wiring support 5.

[0177] This second boundary wall 3 has a peripheral area 12 on one side configured in a handle or hook shape, as can be seen in Figures 1, 2, 7 and 8, which prevents the display unit 20 from moving away from the reference wall 2 in a direction perpendicular to the reference wall 2 when the display unit 20 is inserted.

[0178] This reference wall 2 has notches 13 arranged in a grid, which are shown in FIG. 3 and serve to fix a display unit 20, which will be discussed further below.

[0179] In FIG. 1, the display unit 20 is in a position such that it can be pushed onto the rack rail 1 from below in the direction of the second demarcation wall 3 by a linear movement parallel to the reference wall 2 .

[0180] The display unit 20 has a housing 21 with a rear wall 22. In this case, the rear wall 22 is the portion of the housing 21 that is closest to the reference wall 2 when inserted into the rack rail 1, as is clear from FIG. 2 . On the side opposite the rear wall 22 is a front wall 23 that is provided with a screen 24. The front wall 23 has a stepped portion at its upper end that is configured to accommodate the peripheral region 12 of the rack rail 1. The housing 21 between the front wall 23 and the rear wall 22 is formed by side walls 25. The side walls 25 that extend along the front side of the display unit 20 have cable support slits 26, the vertical wall surfaces of which extend approximately parallel to the rear wall 22. The cable support slits 26 are provided to accommodate the cable support 5 and are sized to fit the dimensions of the cable support 5.

[0181] The housing 21 has housing openings on the rear wall at the wire support slits 26, through which contacts 27 protrude from the housing 21 into the wire support slits 26. These contacts 27 are realized by a group of metal contact belts 27.

[0182] These metallic contact belts 27 are shown in detail in Figures 6A and 6B. Figure 6B illustrates the structure or shape of one contact belt 27, which has a first end section 28 soldered to housing or display electronics 29, only partially shown. Additionally, this contact belt 27 has a second end section 30 configured or formed to contact one of the electrical wires 6, as shown in Figure 6A.

[0183] This second end section 30 has a raised shape 31 as a contact zone, which is also part of the metallic contact belt 27, which can be seen in the side view of the display unit in FIGS.

[0184] In this embodiment, as can be seen in Figure 6A or 6B, both end sections 28, 30 are arranged parallel but offset, so that the contact belt 27 forms a step. This step allows the elastic material to have a large spring deflection and to distribute the bending load. At the same time, this step overcomes the gap (level difference) between the plane of the display electronics 29 and the plane of the contacts formed by the electric wires 6.

[0185] 6A, for reasons of clarity, many components of the electronic display unit 20 are not shown in order to be able to see the fixing mechanism 32. This fixing mechanism 32 is realized as one piece and has two fixing hooks 33 and a button 34 connected thereto. This fixing mechanism 32 further contacts a spring element 35 realized as a coil spring.

[0186] As can be seen in Figures 4 and 5, the rear wall 22 has fastening housing openings through which fastening hooks 33 protrude.

[0187] Furthermore, FIG. 6A shows a housing connection piece 36 which connects the two housing halves (the front and rear housing halves of housing 21) together in a plug or clamp connection configuration.

[0188] 6A is biased against the housing 21. That is, the spring part 35 acts between the fixing mechanism 32 and the housing 21. Therefore, the spring part 35 pushes the fixing mechanism 32, and thereby the fixing hook 33 and the button 34, away from the wiring support slit 26 in a downward direction relative to the orientation in FIG.

[0189] Now, starting from the arrangement shown in Figure 1, the electronic display unit 22 is pushed parallel to the reference wall 2 in the direction of the second boundary wall 3, so that when the display unit 22 is finally placed and fixed in position within the rack rail 1 as shown in Figure 2, the end section 30 of the contact belt 27 comes into contact with the electric wire 6.

[0190] It should be noted here that the cable support 5 has at its free end a chamfer facing the first delimiting or reference wall 2, which ensures that the raised shapes 31 of the contact belts 27 are raised without problems above the plane of the electric wires 6 when the display unit 22 is pushed from below into its target position on the rack rail 1. In this case, each contact belt 27 is biased. It should also be noted that when pushed further into the rack rail 1, at least two of the three contacts slide their raised contact zones over two of the electric wires 6 until all three contacts finally reach the electric wires 6 with which they are to be contacted, where they are lifted from the cable support 5, i.e. the bias is strengthened (which contributes to an optimal electrical contact of the electric wires 6).

[0191] It should be noted that when the display unit 22 is pushed into the rack rail 1, the fixing hooks 33 slide along the reference wall 2 until they reach the notches 13 in the reference wall 2 and automatically lock into them. In FIG. 3 it can be seen how the display unit 20 is inserted into and removed from the rack rail 1 in a linear manner, since the fixing hooks 33 are slightly spaced from the lower edge of the notches 13. In the inserted state, they contact the lower edge of the notches 13, i.e., the edge furthest from the second demarcation wall 3. The notches 13 shown in FIG. 3 are approximately the same width as the fixing hooks 33 or slightly wider. This allows for a fine but well-defined grid, so that the electronic display unit 20 can no longer be moved continuously along the rack rail 1 but can be clearly set in place.

[0192] 6A , inside the display unit 1, the spring element 35 acts on the housing 21 on the one hand and on the fixing mechanism 32 on the other hand, so that the fixing hook 33 is pressed against the lower edge of the notch 13 in the rear wall 22, thereby pushing the electronic display unit 20 upward in the direction of the second demarcation wall 3. As can be seen in FIG. 2 , the lower edge or side of the wiring support 5, i.e., the side of the wiring support 5 that is farthest from the second demarcation wall 3, abuts against the deepest point of the wiring support slit 26, resulting in a clearly defined mechanical contact point between the electronic display unit 20 and the rack rail 1. The two further contact points thus defined are located between the peripheral region 12 and the upper edge of the front wall 23, and between the reference wall 2 and the region of the rear wall 22 that extends into the region of the electric wires 6. These predetermined contact points make it possible to unambiguously determine the fixed point of the electronic display unit 20 relative to the rack rail 1 or vice versa when the electronic display unit 20 is connected. That is, when the display unit 20 is inserted into the rack rail 1, the spring action of the spring parts 35 causes the display unit 20 to be automatically and reproducibly accommodated in the rack rail 1 in the same shape or in the optimal shape and to have its orientation adjusted.

[0193] Here, when button 34 is pressed, the connection between fixing hook 33 and reference wall 2 is released, and subsequently electronic display unit 20 can be removed from rack rail 1 by tilting it downwards, and possibly even forwards after being lowered by the dimension of cable support 5. When button 34 is operated, fixing hook 33 moves upwards on the one hand, i.e., towards second demarcation wall 3, and moves into electronic display unit 20, i.e., away from reference wall 2, on the other hand, thereby releasing display unit 20 for removal from rack rail 1.

[0194] 4 shows the electronic display unit 20 as seen from the rear, i.e., looking towards the rear wall 22. In this view, the position of the raised features 31 of the metal contact belt 27 is visible through the housing opening in the rear wall 22, where they make electrical contact, so that the display unit 20 can be operated and tested outside the rack rails 1.

[0195] 4 further shows that the rear wall 22 has raised housing ridges 54 arranged in the aforementioned grid pattern, with housing canyons 55 between them. These structures 54 and 55 are of the same width, are rectilinear, and extend at an angle of exactly 90° to the longitudinal extension of the cable support slits 26, i.e., from the upper side wall 25 to the lower side wall 25. The rack rail 1 also has demarcation wall ridges 56 in the area of ​​its first demarcation wall or reference wall 2 parallel to the cable support 5, with demarcation wall canyons 57 between them. These structures 56 and 57 are of the same width, are rectilinear, and extend at an angle of exactly 90° to the longitudinal extension of the rack rail 1.

[0196] These rack rail 1 structures 56 and 57 are offset by one unit cell respectively with respect to the structures 54 and 56 of the housing 25, so that the housing ridge 54 can penetrate into the demarcation wall canyon 57, while the demarcation wall ridge 57 can penetrate into the housing canyon 55. Advantageously, the location of the housing opening for the fixing hook or fixing handle 33 is always at the location of the housing ridge 54.

[0197] These structures 54 to 57 ensure that the display unit 20 is oriented as precisely as possible perpendicular (90°) to the longitudinal extension of the wiring support 5 as soon as it is pushed into the rack rail 1, in order to prevent contact errors and, in some cases, short circuits between the electrical wires 6 that may occur when the display unit 20 is inserted at an angle.

[0198] FIG. 5 shows a side view of the electronic display unit 20, and unlike FIGS. 1 and 2, the display unit 20 is shown without the rack rails 1, i.e., the fixing hooks 33 are also visible.

[0199] FIG. 9 shows a supply device 40 inserted into a lateral end section of the rack rail 1 and coupled thereto.

[0200] The supply device 40 comprises a housing part 41, most of which is shown in broken away form in this figure to ensure a view of the components therein, and a power supply circuit 42, which also has an antenna 43, which is adapted to exchange and process data wirelessly with an access point by means of the antenna 43, and to communicate in a wired manner with the devices on the rack rails 1 or to control these devices and to supply them with power for their operation.

[0201] This supply device 40 has contacts embodied as a second group of metallic contact belts 44, similar to the contacts of the display device 20. Each of these contact belts 44 has a first end section 45 soldered to the power supply circuit 42 and a second end section 46 with an arch shape 47 as a contact zone.

[0202] The first end section 45 and the second end section 46 are arranged roughly parallel to each other and are connected to each other so that each contact point 44 forms a C- or U-shape, thereby enveloping the side edges of the rack rail 1, specifically enveloping them so as to prevent contact outside the desired contact area.

[0203] These contact belts 44 are elastically configured to press their arch shapes 47 against the electric wires 6 with a bias that provides a predetermined contact force, and each contact belt 44 is assigned to exactly one electric wire 6.

[0204] The housing part 41 is open on one side (the left side in the perspective of FIG. 9 ) so that the supply device 40 can be pushed into the rack rail 1 (from the right side in the perspective of FIG. 9 ), with the contact belt 44 sliding along its arch shape 47 along the electric wires 6 to establish a conductive connection. The power supply circuit 42 is pushed behind the reference wall 2 of the rack rail 1, where it is surrounded and protected by part of the rack rail 1. The housing part 41 has a predetermined contact zone by means of which it makes mechanical contact with the rack rail 1 to ensure precise installation of the supply circuit 42 relative to the rack rail 1.

[0205] FIG. 10 illustrates a supply circuit 42 inserted into the rack rail 1, with some components such as the housing part 41 and the antenna 43 omitted for clarity.

[0206] 11 shows a rechargeable storage battery unit 50 comprising a storage battery (or otherwise rechargeable battery) 51 and a mounting element 52, connected to the supply equipment 40 by a cable (not shown). The mounting element 52 is realized by means of three magnets arranged in a triangle and has contact surfaces for resting flat on the rack side part 53 made of steel of the rack. The rack bottom has been removed from the rack to make the storage battery unit 50 visible.

[0207] The rack rail 1 is attached at a right angle to this rack side portion 53 .

[0208] During maintenance, the entire battery unit 50 can be easily removed and replaced due to the magnetic connection.

[0209] In Figure 14, one section of the rack rail 1 and the display unit 20 are seen from the rear side. In Figure 15, these two components 1 and 20 are shown separated from each other, and here the housing 21 is also shown with its rear wall cut away so that the interior of the display unit 20 can be seen. In Figure 16, the rack rail 1 with the display unit 20 inserted is seen from the rear side, and Figure 17 shows a cross section along the section line BB in Figure 16. It should be noted here that for reasons of clarity, some of the symbols have not been written in these figures.

[0210] Unlike the display unit 20 shown in the previous figures, here a multi-piece construction of the fastening means is used, in which the housing 21 is provided with two fastening hooks or fastening lugs 58 which are realised as constituent parts of the housing 21. These fastening hooks or fastening lugs 58 fit into the notches 13 of the rack rail 1, as can be clearly seen in Figures 14, 16 and 17.

[0211] 15 shows in detail the button 34, which has two operating protrusions 59 arranged to operate the two fixing hooks or fixing handles 58. Furthermore, in Fig. 17 it can be seen how the operating protrusions 59 work in cooperation with the fixing hooks or fixing handles 58, in other words by means of planes 60 oriented inclined with respect to the longitudinal extension, i.e., inclined surfaces formed on the ends of each component, so that the ends of the components can slide against each other when the button 34 is operated (see also Fig. 17). When the button 34 is operated, the two operating protrusions 59 are pressed against the interior of the housing due to the longitudinal movement of the operating protrusions 59, and the connection between the rack rail 1 and the display unit 20 is released.

[0212] Finally, it is pointed out once again that the figures detailed above are merely examples that can be modified in various ways by those skilled in the art without departing from the scope of the invention, and for the sake of completeness, it is also pointed out that the use of the infinitive "a" does not exclude the possibility of a plurality of relevant features.
