Abstract

The invention relates to a support for replaceable information sheets (9). Such holders are for example used in department stores to advertise special offers. To permit easy on-the-spot replacement of the information sheet (9), it is proposed that one side of the holder is provided with two groups of wiring patterns (3, 4) in an interlaced comb arrangement, the wiring patterns being mutually electrically insulated and connected to the two poles of a d.c. voltage source (7). By using an information sheet (9) consisting of flat material capable of taking an electrostatic charge, such as paper or cardboard, the information sheet (9) can be retained on the holder by using the electric field building up between the wiring patterns (3, 4). The information sheet (9) can easily be pulled off by hand and replaced with a new one. <IMAGE>

Description

Die Erfindung bezieht sich auf einen Wechselhalter für einen Informationsträger, der aus einem elektrostatisch aufladbarem Flachmaterial besteht und wobei der Informationsträger durch elektrostatische Haftung an einer Seite des Wechselhalters gehalten ist.The invention relates to a change holder for an information carrier, which consists of an electrostatically chargeable flat material and the information carrier is held on one side of the change holder by electrostatic adhesion.

Bei einem bekannten Wechselhalter dieser Art besteht das elektrostatisch aufladbare Flachmaterial aus einer durchsichtigen, flexiblen Folie, deren Randbereiche durch mittels Reibung erzeugte elektrostatische Haftung an dem Wechselhalter gehalten sind. Der unter diese Folie legbare Informationsträger wird somit mittelbar durch elektrostatische Haftung an dem Wechselhalter gehalten ((DE-GM 80 05 553).In a known interchangeable holder of this type, the electrostatically chargeable flat material consists of a transparent, flexible film, the edge regions of which are held on the interchangeable holder by electrostatic adhesion generated by means of friction. The information carrier that can be placed under this film is thus held indirectly by electrostatic adhesion to the change holder ((DE-GM 80 05 553).

Wechselhalter dieser Art oder auch anderer Art werden für verschiedenste Zwecke verwendet. In großer Anzahl werden beispielsweise solche Wechselhalter mit unterschiedlichen Informationen in Kaufhäusern verwendet, um auf Sonderangebote hinzuweisen. Sie können mit Schnüren an der Decke aufgehängt werden. Das Anbringen und Wechseln von Informationsträgern ist mehr oder weniger aufwendig. Im Vergleich zu Wechselhaltern, bei denen die Informationsträger aufgeklebt werden und bei denen vor dem Anbringen eines neuen Informationsträgers die alten Informationsträger entfernt werden müssen, ist das Wechseln der Informationsträger aufwendiger als bei einem Wechselhalter der eingangs genannten Art, bei dem lediglich die Folie abgehoben, der darunter befindliche alte Informationsträger entfernt und der neue eingelegt werden muß. Aber auch bei einem solchen Informationsträger ist das Wechseln noch mit einer Reihe von Handgriffen verbunden. Das Wechseln des Informationsträgers kann dabei durch die abzuhebende Folie behindert werden. Hinzu kommt, daß von der den Informationsträger abdeckenden Folie eine Blendwirkung ausgehen kann. Wünschenswert wäre es, wenn der Informationsträger ohne abdeckende Folie sichtbar wäre, wie es bei aufgeklebten Informationsträgern der Fall ist.Exchange holders of this type or of another type are used for a wide variety of purposes. In large numbers, for example, swap holders with different information are used in department stores to indicate special offers. They can be hung from the ceiling with cords. Attaching and changing Information carriers are more or less complex. Compared to change holders, in which the information carriers are glued on and where the old information carriers have to be removed before attaching a new information carrier, changing the information carriers is more complex than with a change holder of the type mentioned, in which only the film is lifted off old information carriers located underneath must be removed and the new one inserted. But even with such an information carrier, the change is still connected with a series of steps. Changing the information carrier can be hindered by the film to be lifted off. In addition, the film covering the information carrier can have a blinding effect. It would be desirable if the information carrier were visible without a covering film, as is the case with glued-on information carriers.

Der Erfindung liegt die Aufgabe zugrunde, einen Wechselhalter für Informationsträger zu schaffen, der bei leichter Auswechselbarkeit der Informationsträger ohne abdeckende Folie auskommt.The invention has for its object to provide an interchangeable holder for information carriers, which does not require a covering film with easy interchangeability of the information carriers.

Diese Aufgabe wird erfindungsgemäß bei einem Wechselhalter der eingangs genannten Art durch ein über die Seite des Wechselhalters verteiltes Netz von zwei Gruppen ineinandergreifender und gegeneinander elektrisch isolierter Leitungszüge gelöst, die zur Erzeugung eines elektrostatischen Feldes an den beiden Polen einer Gleichspannungsquelle angeschlossen sind.This object is achieved according to the invention in an interchangeable holder of the type mentioned at the beginning by a network of two groups of interdigitated and mutually electrically insulated cable runs distributed over the side of the interchangeable holder, which are connected to the two poles of a DC voltage source in order to generate an electrostatic field.

Bei dem erfindungsgemäßen Wechselhalter entsteht ein elektrisches Feld zwischen den beiden Gruppen ineinandergreifender Leitungszüge, das den elektrostatisch aufladbaren Informationsträger anzieht. Die Haltekraft reicht einerseits aus, den Informationsträger flach anliegend an der Seite zu halten, andererseits erlaubt sie ein Abziehen des Informationsträgers von der Seite. Das Auswechseln der Informationsträger läßt sich deshalb ohne großen Aufwand durchführen. Es ist nicht mehr erforderlich, den eventuell aufgehängten Wechselhalter zu demontieren und für einen Wechsel des Informationsträgers vorzubereiten. Nach Abziehen des alten Informationsträgers steht er für den neuen Informationsträger unmittelbar zur Verfügung.In the interchangeable holder according to the invention, an electric field is created between the two groups of interlocking cable runs, which is electrostatic attracts rechargeable information carriers. The holding force is sufficient, on the one hand, to hold the information carrier lying flat against the side, on the other hand, it allows the information carrier to be pulled off the side. The information carriers can therefore be replaced without great effort. It is no longer necessary to disassemble the possibly mounted change holder and prepare it for a change of the information carrier. After removing the old information carrier, it is immediately available for the new information carrier.

Es ist nicht erforderlich, daß die ineinandergreifenden Leitungszüge sich über die gesamte Seite gleichmäßig verteilen. Die Leitungszüge sollten nach einer Ausgestaltung vor allem in den Randbereichen der Wechselhalterseite vorgesehen sein, weil sich sonst die Ränder eines sehr flexiblen Informationsträgers lösen können.It is not necessary for the interlocking cables to be distributed evenly over the entire side. According to one embodiment, the cable runs should be provided especially in the edge areas of the change holder side, because otherwise the edges of a very flexible information carrier can come loose.

Ein wirksames elektrisches Feld läßt sich mit einem übersichtlichen Bild von Leitungszügen verwirklichen, wenn die Leitungszüge kammartig ineinandergreifen.An effective electric field can be realized with a clear picture of cable runs if the cable runs intermesh like a comb.

Die Leitungszüge lassen sich leicht durch Aufdrucken einer leitfähigen Paste herstellen. Insbesondere ist nach der Erfindung vorgeszehen, daß sich die Leitungszüge in oder auf einem flexiblen, nicht dehnfähigem Material, wie papierartiges Faservlies aus thermisch verschweißten Hochdruckpolyäthylen-Fasern befinden, das auf einem formsteifen Körper des Wechselhalters befestigt ist. Da das Leiterdruckbild sich auf flexiblem, nicht dehnfähigem Material befindet, läßt es sich im Druckverfahren nicht nur leicht herstellen, sondern erlaubt auch dem Benutzer eine verschiedene räumliche Gestaltung. So kann er als formsteifen Körper eine Trommel oder eine Platte, insbesondere ebene Platte verwenden.The cables can be easily made by printing a conductive paste. In particular, it is provided according to the invention that the cable runs are in or on a flexible, non-stretchable material, such as paper-like nonwoven fabric made of thermally welded high-pressure polyethylene fibers, which is fastened to a rigid body of the interchangeable holder. Since the printed conductor image is on flexible, non-stretchable material, it is not only easy to produce in the printing process, but also allows the user a different spatial design. He can use a drum or a plate, in particular a flat plate, as a dimensionally stable body.

Um das elektrostatisch aufladbare Flachmaterial möglichst wirksam und sicher zu halten, sollte in dem Wechselhalter als Gleichspannungsquelle ein Transformator mit Gleichrichtern eingebaut sein, so daß sich eine hohe Spannung aufbauen läßt. Da für das Halten praktisch keine Energie benötigt wird, wirdc nur ein Transformator äußerst geringer Leistung benötigt.In order to keep the electrostatically chargeable flat material as effective and safe as possible, a transformer with rectifiers should be installed in the changeable holder as a direct voltage source, so that a high voltage can be built up. Since practically no energy is required for holding, only a transformer of extremely low power is required.

Im folgenden wird die Erfindung anhand einer Zeichnung näher erläutert, die ein Ausführungsbeispiel darstellt.The invention is explained in more detail below with the aid of a drawing which represents an exemplary embodiment.

Auf einer rechteckigen, formsteifen ebenen Platte 1 ist ein papierartiges Faservlies 2 aus thermisch verschweißten Hochdruckpolyäthylen-Fasern aufgeklebt. Vor dem Aufkleben ist das Faservlies mit zwei Gruppen, kammartig ineinandergreifender Leitungszüge 3,4 aus einer leitfähigen Paste, zum Beispiel Silberleitlack, bedruckt. An einer Ecke sind die beiden Gruppen an den Stellen 5,6 durchkontaktiert. Durch ausreichenden gegenseitigen Abstand sind die einzelnen Leitungszüge 3,4 elektrisch gegeneinander isoliert. Im Bereich der durchkontaktierten Stellen 5,6 ist in einer Box eine Gleichspannungsquelle 7 mit einem elektrischen Transformator und einer Gleichrichterschaltung in der Platte 1 eingebaut. Der Transformator ist über ein Anschlußkabel 8 am Netz anschließbar. Die Gleichspannungsquelle 7 weist an mit den Durchkontaktierungsstellen 5,6 entsprechenden Stellen Ausgangskontakte auf.A paper-like non-woven fabric 2 made of thermally welded high-pressure polyethylene fibers is glued to a rectangular, dimensionally stable, flat plate 1. Before gluing, the nonwoven fabric is printed with two groups, comb-like interlocking lines 3, 4 made of a conductive paste, for example silver conductive lacquer. At one corner, the two groups are plated through at positions 5, 6. The individual cable runs 3, 4 are electrically insulated from one another by sufficient mutual spacing. In the area of the plated-through points 5, 6, a DC voltage source 7 with an electrical transformer and a rectifier circuit is installed in the box 1 in a box. The transformer can be connected to the network via a connecting cable 8. The DC voltage source 7 has output contacts at points corresponding to the plated-through holes 5, 6.

Sobald der Wechselhalter mit seinem Anschlußkabel 8 am Netz angeschlossen ist, baut sich zwischen den beiden Leitungszügen 3,4 ein elektrisches Feld auf. Wird auf die diese Leitungszüge 3,4 tragende Seite des Wechselhalters ein Informationsträger aus elektrostatisch aufladbarem Material, wie Papier oder Karton, aufgelegt, dann lädt sich dieses auf und bleibt an dem Wechselhalter haften. Die Haltekraft reicht aus, um den Informationsträger 9 zu halten, ist aber nicht so groß, als daß der Informationsträger 9 von Hand nicht beschädigungsfrei abgezogen werden kann.As soon as the change holder with its connection cable 8 on the network is connected, an electric field builds up between the two lines 3, 4. If an information carrier made of electrostatically chargeable material, such as paper or cardboard, is placed on the side of the interchangeable holder carrying these cable runs 3, 4, this is charged and remains attached to the interchangeable holder. The holding force is sufficient to hold the information carrier 9, but is not so great that the information carrier 9 cannot be removed by hand without damage.
