Fig. 1 shows a rail system 10, which comprises two horizontally extending rails 12 and a vertically extending rail 14, and is connected to which an information reproducing device 32. Preferably, for example, a shelf 48 of a supermarket comprises a plurality of horizontal rails 12 and vertical rails 14. Either form the rails 12, 14 when the shelf 48 is a load-bearing structure or the

Rails 12, 14 are connected to the supporting structure of a shelf 48 (see FIG. 2). This can be done for example by gluing, screwing or by clamping. The use of the present

Rail system 10 is not limited by a connection by a rack 48, but may be connected to appropriate structures on different occasions. In an attachment to a shelf 48 Fig. 1 shows a front view of the rail system 10, it means that the shelf 48, which is not shown in Fig. 1 would be partially obscured in Fig. 1 of the rail system.

The horizontal rails 12 are in the plan view of FIG. 1, 12a an opening portion facing the viewer. The opening portion 12a is configured such that the horizontal rail 12 is formed as a holder 16 for display devices 18th Fig. 1 shows a case that

Viewer facing the front of the display device 18 which includes an E-Ink display 19, which is characterized, for example, price information of a product or other.

E Ink displays are 19 display techniques, which attempt, the

simulate appearance of ink and color on paper. E-Ink display 19 reflect light like ordinary paper, so it is passive

(Unlit) ads, which are very low by a

Power consumption distinguished. There is only one power supply necessary when the display of the e-ink display is changed 19th Benefits of E-Ink display 19 are in this case that an image content due to the short distance of the imaging elements to the surface from any angle looks the same, among other things, that the display does not flicker, it is also flexible to manufacture very thin and light, and with the appropriate design and that the E-Ink display 19 both in normal room light and in bright

Sunshine is easy to read, because the imaging elements are reflective.

The display devices 18 are in a clamping but still included in the horizontal rails 12 slidably. Thereby, the possibility is created that the display devices 18 are placeable on preferred variable sites of a shelf 48th This is important as a position of the display device 18 has to be changed on the shelf 48, depending on the type of products.

The display device 18 selectively display the price,

Product name or the price and the product name. It is also possible that promotions can be displayed. To increase the

Attention of customers can choose a multi-colored display of information when needed. A number of the display devices 18 within the holder 16 of the horizontal rails 12 is, in principle, freely selectable and ultimately present only limited by physical space requirements of the display devices 18, that is, the display devices 18 can not be pushed to one another or one above the other. so a maximum number of the display device 18 per horizontal rail 12 is the ratio of a lateral dimension of the opening portion 12a and a lateral extent of the display device 18. In the present case, all display device 18, the same spatial dimensions. However, it is also possible 18 to provide the display devices with different spatial dimensions, in particular different widths.

In FIG. 1 12 a first projection 20a and a second projection 20b formed at a lower edge of the horizontal rail 12 extending along an extending direction of the horizontal rail 12 12a delimit the opening area and behind it spaces on an upper edge of the horizontal rail of the cover horizontal rail 12th In FIG. 2 it is shown that the protrusions 20a, 20b enclose together with the horizontal rail 12 each have a rectangular space portion 22, so that in this rectangular region of space 22 electrical conductors 24a, 24b are accommodated in clamping. Subsequently, the electrical conductor which is disposed between the upper projection 20a and the horizontal rail 12, referred to as a first electrical conductor 24a and the electric conductor, which is disposed between the lower protrusion 20b and the horizontal track 12 as the second electrical conductor 24b , In Fig. 1, the electrical conductors 24a, 24b not visible because they are hidden by the projections 20a, 20b. This provides a visually pleasing appearance is created as running cables in general arousing quality impression for the viewer. At the same time nevertheless ensured that the electrical conductors 24a, 24b with the

Display devices 18 come into contact, so that data and power can be transmitted, which will be explained in detail below.

By means of the at least one vertical rail 14 is provided a connection between one or more horizontal rails 12 which are arranged offset from one another in parallel. An opening portion of the vertical bar 14 is located on a side remote from the viewer side, so that an optically high-quality appearance results. In an inner area of ​​the vertical rail 14 extend further electrical conductor, said verlaufenen in the vertical rail 14 conductors each of the first electrical conductor 24a of a horizontal rail 12 with a further first electrical conductor 24a of a further horizontal rail 12 and each of the second electrical conductor 24a a horizontal rail 12 connects with another second electrical conductor 24b of the horizontal rail further 12th

In Fig. 1 the rail system 10 having two horizontal rails 12 and a vertical rail 14 is shown. However, this does not constitute a restriction. Depending on requirements, the rail system 10 may be expanded by further horizontal and vertical rails 12, 14th is a to the individual horizontal and vertical tracks 12, 14 to be connected together, used in the top view T-shaped connector 26th The T-shaped fitting 26 is in this case by means of

mechanical clamping in the rails 12, 14 inserted. The T-shaped connecting piece 26 includes metallic pins 28, said metallic pins 28, the above-mentioned compound of the first lines 12 and second lines 14 of the horizontal rails 12 forming, by forming with them a common contact surface. Here, the

28 taken metallic pins within the T-shaped connecting piece 26 slidably; are the metallic pins 28 in a disengaged position, these make the connection between the rails 12, 14th In an engaged position of the metallic pins 28, the T-shaped connecting pieces 26 can be used as the end pieces 30, as shown in FIG. 1. The two connecting pieces 26 in Fig. 1 show, respectively, on the horizontal rails 12 side facing the metal pins 28 in a disengaged position and on the horizontal rails 12 side facing away from the metal pins 28 in an engaged position. Fig. 2 shows a side view of the information reproducing device 32 and the rail system 10. In the side view is evident that the horizontal rail 12 forms a C-shaped profile with flat outer sides 34. The first projection 20a and the second projection 20b to limit the opening portion 12a, in which the first projection 20a, a first slot 36a and 20b, a second slit 36b is incorporated in the second projection. The slots 36a, 36b are designed such that in the slots 36a, 36b, a transparent protective film is insertable 40 that the E-Ink display 19 of the display device 18 and the heads 24a, 24b and protects at the same time a point of view of a viewer to the display device 18 not disabled.

Perpendicular to the extension direction of the horizontal rail 12 have the projections 20a, 20b have a length that is substantially in each case a

Diameter of the first electrical conductor 24a and a diameter of the second electrical conductor 24b, respectively. The space portion 22 between the projections 20a, 20b and the horizontal rail 12 is also formed so that the first electrical conductor 24a and the second electrical conductor 24b clampingly between the rail 12 and the respective projection 20a, are housed 20b and thereby from view of the viewer are hidden, so that the C-shaped profile forms a bracket 38th

In the present case 18 includes the display device, the E-Ink display 19, which is received clampingly between the first conductor 24a and the second conductor 24b by its own curvature and is held. Here, the E-Ink display 19 and the electrical conductors 24a, 24b by means of at least one contact point 44 with each other, so that data and power through the electrical conductor 24a can be transferred 24b on the display device and thereby to the E-Ink display 19th

On the side remote from the viewer side of the horizontal rail 12, a first adhesive layer 46a is attached. By means of this first adhesive layer 46a is the horizontal rail on a shelf 48 attached, so that the E-Ink display 19 is arranged in an angle α of 0 degrees to a viewer.

However, the E-Ink display 19 is well below eye level of the viewer, a viewing angle α of greater than 0 degree is preferable. For this purpose, an adapter wedge 50 46a attachable to the first adhesive layer, on which the first adhesive layer, a second adhesive layer is attached 46b 46a opposite side of the adapter wedge 50, which 50 side remote is connected to the rack 48, in turn, with its adapter wedge. Depending on the shape of the adapter 50 thereby a desired wedge angle α can be set for the E-Ink display 19th

Fig. 3 shows a hierarchy tree of a data communication device 52 to the information reproducing device 32 of FIG. 1 and FIG. 2. The data, which may be, for example, the purchase prices of a supermarket for distinction of various products, be by a user in a store on a computer 56 having a server similar system processed and provided. Here, the data communication device 52 is not limited to application in a supermarket, but can be used for numerous applications in which display devices are to display 18 variable content that can be flexibly controlled by a central computer 56th It is also understood that the data must not be processed necessarily via the computer 56 in a store, but that the alternative case is included that the

necessary data from a central station to the individual stores are transferred.

The data are transferred from the computer 56 to a first industry radio module 58, which transmits the data by means of radio signals 60 at a frequency of 868 MHz and a range of 15 meters in different spatial directions. The radio signals 60 are sent to an access point 64 at least, wherein each access point 64 has a second industry radio module 62 with which the radio signals are received 60th Further, the access point 64 includes a first infrared module 70, a power supply 66 for the power supply and a microprocessor unit 68 for processing and intermediate storage of the data that was transmitted by the radio signal 60th The at least one access point 64, the data to at least one

Master module 72 by the data through the first infrared module 70 of the access point 64 to a second infrared module 74 of the master module are sent 72nd The number of master modules 72 and the access point 64 is arbitrary in principle, whereby in general more master modules 72 as

Access points 64 are used, so that parallelization and

Simultaneity of data transmission can be guaranteed, which increases an efficiency of data transfer. In Fig. 3, two access points 64 and three master modules 72 are provided, for example. The access points 64 may here, for example on the ceiling of

Space are fixed and from this position the data to the

Send master modules 72 that are connected to the shelves 48th The data transmission between the access points 64 and the master modules 72 via infrared signals 76 is power efficient than a data transmission via

Industrial radio. Further, the infrared modules 70, 74 are priced lower than corresponding Funkpendants. Generally are often still

Radio signals used because they can overcome made diffraction technical reasons obstacles easier due to the smaller wavelength, arranged between a transmitter and a receiver. but this is avoided in the present. As already indicated, is created by an arrangement of the access points 64 on the ceiling and a connection of the master modules 72 in upper portions of the racks 48, a situation in which any objects interfering with the infrared communication. The data for controlling the display device 18 are thus transferred from the first infrared module 70 of the access point 64 over a short distance to the second infrared module 74 of the master modules 72nd

The Master Module 72 also comprise a further microprocessor unit 78, which processes the data, a battery 80, which provides a low voltage, and an interface 82 that allows a connection to the first electrical conductor 24a and to the second electrical conductor 24b. Via nodes 84 is a branch of the electrical conductors 24a, 24b makes it possible, so that these can be connected to a plurality of rows 86a, 86b, consisting of a plurality of display devices 18. In Fig. 3, respectively a first row 86a and a second row 86b are a plurality of

Display devices 18 via the electrical conductors 24a, 24b with the

Master module 72 is connected. Here, along the rows 86a, 86b

entered wildcard symbols 87th The wildcard symbols 87 are

to be understood that instead of wildcard symbols 87 also further display devices 18 along the rows 24a, 24b may be connected. The batteries 80 of the master modules 72 provide at the same time provides a power supply of the display devices 18th Advantageously, no battery element 80 must be replaced at each individual display device 18, only the battery 80, which is connected to the master module 72 in case of failure of the battery. Characterized both an effort during replacement of the batteries is reduced 80 and at the same time also reduced production costs, since otherwise each display device 18 has to be provided with its own power supply. In addition, a power consumption is the

Display device 18 and the master module 72 is so low that the battery must be replaced in section 80 in only about once a year. This is also undesirable replacement operation, the battery 80 can be replaced for example by a battery, which is chargeable by a solar cell module which is additionally connected to the master module 72nd

The electrical conductors 24a, 24b, thus connecting the display devices 18 of the master modules 72, being transmitted through the electrical conductors 24a, 24b, both control data as well as the energy for the display devices 18th For this purpose the second electrical conductor 24b form of the designed as a ground reference potential. The data and power transmission takes place via the first electrical conductor 24a via a so-called single-wire bus technology in bidirectional half-duplex method.

The single-wire bus describes a serial interface, which works with a data wire, both as a power supply as well as send and

Receiving line is used. The single-wire bus is misleading because also a ground connection is still required, which is herein formed by the second electrical conductor 24b. the single-wire bus with an operating voltage of between 2.8 V and 12 V is preferably operated. The

Power consumption of single-wire bus devices is between 2 and μΑ few mA.

The attribute bidirectional indicates that a data transmission in both directions takes place point to point. The term originally comes from the radio transmission in which signals simultaneously in both directions

could be replaced. Is it possible to receive both data with an interface 82 and send, then this interface is referred to as 82 bidirectional. If data is transferred at the same time in both directions on a same medium, so it is called a full-duplex method. A transmission in only one direction at a time is called the half-duplex method.

The basic components of the display device 18 are shown in Fig. 4. Each of the first electrical conductor 24a and the second electrical conductor 24b have in Fig. 4 originate in a symbol which the

represents battery 80th The icon to the left of the battery icon 80 is to show that the data transmission from this connection point of the electrical conductors 24, 24b goes out. The first electrical conductor 24a branches off from the battery 80, and contacts the display device 18 at a first contact node 90. The second electrical conductor 24b also goes from the battery 80 and contacts the display device 18 via the second contact node 92 and the third contact node 94th The

Display device 18, which is formed as in the form of a flexible label is, by the first, second, third contact node 90, 92, 94 by means of its own spring force clamping and once displaced in the form of a three-point system between the first electrical conductor 24a and the second electrical conductor 24b held horizontally displaceable. Here, the contact node points 90, 92, 94 formed as raised portions 90, 92, 94 of the flexible label.

The power and data are transmitted via the first contact node 90 in an amplifier and filter circuitry 96 of the display device 18th The amplifier and filter circuitry 96 includes appropriate resistors 98, a capacitor 100 and a transistor 102 for processing and use of data and energy. By the user desired product designation information filter circuit system 96 are forwarded to a logic unit 104 through the amplifier and which controls the display screen 19, which is constructed as E-Ink display 19, wherein the power supply of the E-Ink display 19 at the same time through the first electrical conductor 24a is provided. In the present case the logic unit is designed as a display driver 104 104th Each display device 18 has its own fixed address and waiting for a direct response by the master module 72. The E-Ink display 19 requires only during a change its display minimum flows and is otherwise in a standby mode, which virtually no current consumed so that 80, the e-ink display 19 the price of a product still distinguishes itself in case of failure of the battery.

Fig. 5 shows an alternative embodiment of the master module 72. In this case, the master module 72 includes in addition to the second infrared module 74 a

is cable link 108 and a third radio module 1 10. This

allows the data transmission need not take place via the infrared module 74, but that, for example, the master module 72 is connected by means of the cable connection 108 to the access point. Alternatively, the master module 72 may be directly connected by means of the cable connection to the computer 56 and receive the control data for the display device 18 directly. In addition, the power supply may be provided by the cable connection 108 so that the master module 72 no battery 80 requires more. Further alternatively, the data transmission can also be carried out via the third radio module 1 10 so that a direct connection between the computer 56 and the master module 72 can be manufactured, so that it can be dispensed with, the access points 64th

The invention operates as follows:

First, the rail system 10 is aligned to a shelf 48, that the products to be referred to the above or below

Rail system 10 are located. In a next step, a display device 18 is selected for each to be designated product which is formed as a flexible label so that it can be curved by personnel for insertion into the rail. the display device 18 is located in the rail, the staff reduces the pressure on the display device 18 so that the curvature decreases, and the display device 18 has a tendency to form again a flat surface. Here is the

Display device 18 with its upper end in contact with the first electrical conductor 24a and with its lower end to the second

electrical conductor 24b. By the power of the display device 18, the curvature of its own counters, a contact pressure on the first electrical conductor 24a and the second electrical conductor 24b is generated, which can be seen in Fig. 2. By an own spring force of the display device 18, the display device 18 at the same time clamping and horizontally displaceable between the electrical conductors 24a 24b added, wherein the

Display device 18 is so connected to the electrical conductors 24a, 24b, can be that a power and data transfer take place.

The data to be processed by a user by means of a

Graphical user interface rendered on the computer 56 and by means of

Radio signals sent to the access point 64 60th In general, a data transmission via infrared has a lower data rate than a wireless link, but by the radio signals are transmitted to multiple Access Points 64 60 which, in turn, the data to multiple

Master modules send 72 via infrared signals 76, is a parallelization of the data transmission is possible, which is able to increase the data transmission rate. Here, 64 store the access points the received data between the computer 56 and send them constantly to the master modules 72. When all data has been transmitted from the computer 56 correctly on the access points 64, the computer 56 receives a confirmation of

successful transmission of the data and, optionally, an appropriate error code, if the transmission was incorrectly executed.

The Master Module 72 distribute the data to the display devices 18 through the first electrical conductor 24a via single-wire bus technology in bidirectional half-duplex method in which the data are modulated on the first electrical conductor 24a by means of voltage modulation.

Each display device 18 has its own fixed address and waiting for a direct response by the master module 72. A measured

Data protocol ensures correct data transmission and representation through the E-Ink display 19. The second electrical conductor is here as

formed reference potential.

Display devices 18 the data, but only react to

Display devices 18 which are addressed by the respective address specified in the transfer protocol.

In return, the display apparatus 18 is feedback through a defined load on the first electrical conductor 24a back (for example, by generating a 20 mA current flow in the data clock). Here, always sends only one display device, and then only if no other information on the first electrical conductor 24a is present. The master module 72 again detects this current flow and prepares from these current changes again data, which in turn transmitted to the computer 56 and confirm a successful ads on the E-Ink Display 19th
