- a presentation or exhibition stand is the first port of call for a new customer and is therefore particularly important as a figurehead for the company presenting itself. For this reason, increasing importance is attached to the visual impression and also to the possibilities of different and, in particular, flexible presentations.

It would therefore be desirable to make it easier for designers and decorators to work with live wall elements. Furthermore, it would be desirable to reduce the time it takes to design or redesign a shop window. This is particularly true in light of the fact that shop windows are often redesigned outside of normal opening times, including at night or on weekends.

- the contact needles can be configured to penetrate the coating and establish a connection with the respective conductor tracks.
- the contact needles can pierce through or into the wall element. It is also conceivable that the electrical conductor tracks are integrated, in particular woven into, the cover.
- first electrical conductor tracks of the cover can be connected to the first rear connection contact and second electrical conductor tracks of the cover can be connected to the second rear connection contact.
- the cover can optionally be viewed as part of the wall element.
- the current collector can be set up to establish an electrical connection with the first and the second conductor track when it is placed on the wall element and to supply the tapped voltage to a consumer.
- Advantages of the proposed solution compared to the conventional shop or exhibition stand construction can in particular consist in the fact that complex cabling of the individual electrical loads attached to the presentation element can be dispensed with. Instead, the consumers can be flexibly attached to the presentation element on the fly. Expensive corrections can therefore be omitted.
- the current-carrying wall element can be supplied with current before the consumer is attached and the result can be assessed immediately. There is no need for complex rewiring.
- the current collector can either be attached as such to the wall element and the tapped current can be fed to a consumer, for example wired, or can be integrated into a holder or an electrical consumer.

- the first and the second electrical connection contact can be arranged rotationally symmetrically on the back of the carrier plate. This can facilitate the positioning.

This can enable higher current flows and thus higher outputs of an electrical device 5 connected to the current collector 20.
- Fig. 23 shows a representation of a current collector 20 with an arrangement of three contact needles 21a-21c in connection with a rectifier 22.
- FIG. 24 shows a corresponding illustration of a current collector 20 with an arrangement of four contact needles 21a-21d in connection with a rectifier 22.
- a diode bridge rectifier is shown, but other types of rectifiers can also be used.
- One advantage of this solution is a simple, cost-effective structure which can also be easily scaled for a larger number of contact needles 21a-f.
- An output voltage of defined polarity is provided at the outputs 24a, 24b, which can be supplied to an electrical consumer 5.
- a to C show a top view (C) and a first and a second side view (A, B) of a specific embodiment of a current collector 20 for an electrical consumer.
- 26 shows a perspective illustration of this current collector 20.
- a current collector can also be referred to as a needle connector.
- the contact needles 21a-21d can be arranged on an underside or first housing side and the power connections 24a, 24b can be arranged on an upper side or second (opposite) housing side.
- the rectifier circuit 20 shown in FIG. 24 can be integrated into the current collector 20. A compact, easy-to-handle component can thereby be provided.
- the current collector has four contact needles, which can be arranged, for example, similar to the illustration shown in FIG. However, other arrangements or numbers of contact needles can also be provided.
- the current collector 20 can be designed such that a straight line through the first and second contact needles 21a, 21b with a horizontal or vertical alignment of the current collector intersects a horizontal or vertical axis of the current collector at an acute angle, in particular at an angle of not more than 30 °, in particular at an angle of not more than 15 °, in particular at an angle of not more than 5%.
- FIG. 27 shows a perspective view of a current collector 20 with a magnet holder 30.
- the magnet holder 30 can have one or more magnets 32 to attach the magnet holder 30 and thus the current collector 20 to a wall element 10, as shown for example in FIG , to fix.
- the magnet holder may have a receptacle 33 for the current collector 20, here in the form of a groove 33 provided on the magnet holder, which cooperates with a corresponding tongue and groove 27 of the current collector 20.
- the current collector 20 (in particular in connection with the holder 30) can be set up so that the contact needles 21a-d between a contact position in which the contact needles can contact the conductor tracks of the wall element, and a non-contact position in which the contact needles are spaced from the conductor tracks, are movable when the current collector is placed on the current-carrying wall element.
- the current collector 20 can have a spring element 28, for example as shown in FIGS. 25B and 26.
- the magnet holder 30 can optionally also have an insert 33 for an electrical consumer. In this case, the electrical consumer can be set up to come into contact in an inserted position with the output pins or output contacts 24a, 24b arranged on the top of the current collector 20 for the purpose of power supply.
- the current collector 20 in connection with the holder 30 can be set up to be moved from the non-contact position to the contact position by inserting an electrical load into the insert 33.
- a current-carrying wall element as described in the context of the present disclosure, is provided.
- a current collector as described in the context of the present disclosure, is provided.
- the current collector is attached to the current-leading wall element in such a way that a first of the contact needles is one of the first contacted electrical conductor tracks and at least one other of the contact needles contacted one of the second electrical conductor tracks.
- step S204 the position and rotation of the pantograph (or an electrical consumer that has the pantograph or is connected to the pantograph) can be checked.
- step S205 the position and / or rotation of the pantograph can be corrected. Steps S204 and S205 can optionally be repeated iteratively until a desired position and rotational alignment are reached. This can further improve the flexibility in equipping or in the design of such a presentation system. In particular, it is not necessary to define a position and an angular orientation of the electrical loads in advance, since these can be flexibly adapted.
- the shown strictly vertically or horizontally oriented arrangements of the conductor tracks are to be understood as examples, so that they are also thinner, thicker, oblique or otherwise such as circular or meander-shaped can be arranged on the carrier element 15.
- the current collector can interact with the conductor tracks arranged on the carrier element in such a way that at least one first contact needle can come into electrical contact with one of the first conductor tracks and a second contact needle with one of the second conductor tracks.
- Low-voltage systems that work with 12/24 V and are therefore safe to use can be used for the power supply.
- the conductor tracks 11, 12 usually carry a low current, for example 12 or 24 V, so that the risk of injury when handling the proposed wall element 10 or the current collector 20 or an electrical consumer 5 connected to it can be almost ruled out.
- the conductor tracks 11, 12 can be applied to the carrier plate 15, for example, by spraying, gluing or welding.
- conductive varnishes can also be used for the conductor tracks 11, 12, which are sprayed / printed onto the carrier plate 15 (for example by screen printing).
- the wall elements 10 can not only be executed flat, but can also be bent or curved.
- Modern magnets 6 enable magnetic forces of significantly more than 80 kg, so that even large electrical loads 5 or electrical loads 5 arranged in special presentation elements, such as shelves 11 (see FIG. 1), are simply fixed to the respective wall elements 10 can.
- the wall element 10 can also be designed to be flexible, in particular it can be rolled up or unrolled, so that it can be used, for example, as wallpaper or as a floor covering.
- the wall element 10 can be constructed as a sandwich material, which includes the current-carrying conductor tracks 11, 12 in the structure and e.g. can be used or mounted / applied as wallpaper / carpet (roll goods) or sheet material.
- the sandwich structure can be done as follows:
- the over train 18 (surface material) is as a thin, penetrable, flexible material, behind it the conductor tracks 11, 12 are arranged on an insulating material and behind it is the carrier material 15 made of plastic and / or made of magnetic or magnetizable material, such as steel.
- the current collector 20 and / or the electrical consumer 5 can also be intelligent or programmable. Data can be accessed by modulating a Signals are transmitted to one or both of the conductor tracks 11, 12 by means of so-called power line communication (PLC) or by means of wireless communication or optically.
- PLC power line communication
- various current collectors 20 and / or electrical loads 5 can be controlled in a targeted manner. For example, is a scarf
- a bus system can also be provided in which the electrical conductor tracks 11, 12, the current collectors 20 and / or the electrical loads 5 represent part of the bus system and with which individual loads 5 can be addressed / controlled individually.
- a wall element can also be set up under a wall covering, such as a fiberglass wallpaper and can be used, for example, in the smart home or in a museum application, with electrical consumers such as lighting devices for pictures or others Exhibits or monitors that explain the exhibits, can be supplied with electrical energy.
- a wall covering such as a fiberglass wallpaper
- electrical consumers such as lighting devices for pictures or others Exhibits or monitors that explain the exhibits, can be supplied with electrical energy.
- the proposed system can also be used in an office or a private household, in which case it can then be arranged, for example, under a surface made of textile, foil or wood veneer or other wall surface materials.
