Description

Die Erfindung betrifft eine Bildwechseleinrichtung, bei der Plakate oder sonstige Werbemittel von mindestens zwei unterschiedlichen Seiten dem Betrachter visuell zugänglich sind.The invention relates to an image changing device, in which posters or other advertising means of at least two different sides of the viewer are visually accessible.

Vorwiegend zum Zwecke der Werbung werden Bildwechseleinrichtungen eingesetzt, die in der Lage sind, mehrere Bilder (z.B. Plakate oder bedruckte Folien) zu magazinieren und im Wechsel zu zeigen.For the purpose of advertising, image exchanging devices capable of magazineing and interchanging multiple images (e.g., billboards or printed films) are used primarily for advertising.

Die in der Außenwerbung (Outdoor-Bereich) verwendeten Bildwechsler sind vorwiegend auf großformatige Bilder ausgelegt, damit sie auch aus der Entfernung wahrgenommen werden können. Außerdem entfällt dort meist der Zwang zu einer platzsparenden Bauweise. Anders ist es bei sogenannten Indoor-Geräten, also Bildwechslern für den Innenbereich (z.B. Schalterhallen, Ladenlokale oder dergleichen). Sie sind vorwiegend auf ein Bildformat von DIN A1, A2 oder A3 ausgelegt und müssen so beschaffen sein, daß sie auch bei beengten Platzverhältnissen bedient werden können. Dies gilt namentlich für den Bildwechsel und für die Wartung, z.B. die Innenreinigung, die ein Öffnen der Geräte erforderlich machen. Ausschwenkende Türelemente erschweren hierbei das Handling.The image changers used in the outdoor advertising (outdoor area) are mainly designed for large-format images, so that they can be perceived from a distance. In addition, there usually eliminates the need for a space-saving design. The situation is different with so-called indoor devices, that is, indoor image changers (e.g., ticket halls, shops, or the like). They are mainly designed for a picture format of DIN A1, A2 or A3 and must be such that they can be operated even in confined spaces. This applies in particular to the image change and maintenance, e.g. the internal cleaning, which makes it necessary to open the devices. Swiveling door elements make handling more difficult.

Bildwechseleinrichtungen werden heute manchmal so bestückt, daß für den Betrachter die sich bewegenden Plakate, Werbemittel oder dergleichen, lediglich von einer Seite sichtbar und auf der, der sichtbaren Seite gegenüberliegenden Fläche üblicherweise mit einer Verkleidung versehen sind.Picture changing facilities are sometimes equipped today so that the viewer, the moving posters, advertising or the like, visible only from one side and are usually provided on the opposite side of the visible side with a panel.

Zum allgemeinen Stand der Technik zählen sogenannte stationäre Plakatwände, insbesondere zur Aufnahme von Großplakaten, die bedarfsweise mit von mindestens zwei Seiten betrachtbaren Plakaten, Werbemitteln oder dergleichen ausgestattet werden können. Bei einem Großplakat sind in der Regel lediglich die Vorder- und die Rückseite bestückbar, wobei die Attraktivität bei der Betrachtung der Plakate, Werbemittel oder dergleichen, über eine bestimmte Zeit gesehen, eher nachläßt. Aus diesem Grund werden heute vielfach Bildwechseleinrichtungen eingesetzt, die mit mehreren Plakaten, Werbemitteln oder dergleichen bestückt sind und dem Betrachter abwechslungsreiche Motive zeigen. Wie bereits angesprochen, jedoch nur von einer Seite.The general state of the art includes so-called stationary billboards, in particular for receiving large posters, which can be equipped, if necessary, with at least two pages viewable posters, advertising materials or the like. In a large poster are usually only the front and the back equipped, the attractiveness of the consideration the posters, advertising or the like, seen over a certain time, rather diminishes. For this reason, many image changing devices are used today, which are equipped with several posters, advertising materials or the like and show the viewer varied motives. As already mentioned, but only from one side.

Aus der FR-A 1 353 043 ist eine Einrichtung bekannt geworden, bei der die Rollen der Bildwechseleinrichtung von Motoren angetrieben werden, die über elektrische Kupplungen mit den Rollen verbunden sind. Jeder Rolle ist hierbei ein eigener Antrieb zugeordnet. Je nach Wickelrichtung ist immer nur ein Motor im Einsatz, der über die zugeordnete Kupplung auf die entsprechende Rolle einwirkt. Die andere Rolle läuft hierbei frei. Durch diese Maßnahme sollen die sich ändernden unterschiedlichen Wickelradien beim Auf- und Abrollen ausgeglichen werden.From the FR-A 1 353 043 a device has become known in which the rollers of the image changing device are driven by motors which are connected via electrical couplings with the rollers. Each role is assigned its own drive. Depending on the winding direction is always only a motor in use, which acts on the corresponding role on the associated clutch. The other role is free here. By this measure, the changing different winding radii are compensated during rolling up and unrolling.

Die EP-A 0 628 942 betrifft ein Verfahren zum Abrollen von in Form eines Bandes angeordneten Werbeanzeigen und Vorrichtungen zur Durchführung des Verfahrens. Zum Einsatz gelangen zwei vertikal angeordnete Rollen, die zur Aufnahme eines Bandes vorgesehen sind. Bedarfsweise können Umlenkrollen vorgesehen sein. Bei mindestens einer Aufwickelrolle ist die Antriebswelle über mindestens eine in Aufwickelrichtung vorgespannte Federeinrichtung mit einem zugeordneten Zylindermantel verbunden. Bei dieser Bildwechseleinrichtung kann eine Werbeanzeige lediglich von einer Seite angeschaut werden.The EP-A 0 628 942 relates to a method of unwinding banded advertisements and apparatus for performing the method. Used are two vertically arranged rollers, which are provided for receiving a tape. If necessary, pulleys can be provided. In at least one take-up roll, the drive shaft is connected via at least one spring device pretensioned in the take-up direction to an associated cylinder jacket. In this image changing device, an advertisement can only be viewed from one side.

In der FR-A 2 448 203 wird eine mehrere Betrachtungsbereiche aufweisende Bildwechseleinrichtung beschrieben, die zwei Aufwickelrollen und Umlenkrollen beinhaltet. Sämtliche Rollen sind vertikal und stationär vorgesehen. Die Umlenkrollen bewirken, dass der Betrachter im jeweiligen Betrachtungsbereich ein parallel zur Vitrinenscheibe verlaufendes Bild anschauen kann.In the FR-A 2 448 203 For example, a picture changing device having a plurality of viewing areas is described, which includes two take-up rollers and deflection rollers. All rolls are vertical and stationary. The deflection rollers cause the viewer to look at an image parallel to the display window in the respective viewing area.

Vorteilhafte Weiterbildungen der erfindungsgemäßen Bildwechseleinrichtung sind den Unteransprüchen zu entnehmen.Advantageous developments of the image changing device according to the invention can be found in the dependent claims.

Mit den erfindungsgemäßen Bildwechseleinrichtungen ist es nun möglich, daß, in Abhängigkeit der Anzahl der einzusetzenden Umlenkrollen, mindestens zwei sichtbare Bereiche gebildet werden, auf denen bedarfsweise unterschiedliche Plakate, Werbemittel oder dergleichen betrachtet werden können. Durch Einsatz mindestens einer, vorzugsweise als Schraubenfeder ausgebildeten Feder im Bereich einer der Rollen können die sich bei gleicher Drehzahl der Antriebswellen beim Auf- und Abrollen des Wickels auf den Rollen einstellenden unterschiedlichen Umfangsgeschwindigkeiten der Wickel ausgeglichen werden. Gleichzeitig wird, bedingt durch die Vorspannung der Feder, der Bandabschnitt zwischen der einen abrollenden Rolle und der Umlenkrolle bzw. der Umlenkrolle und der anderen aufrollenden Rolle straff gehalten, so daß die auf dem jeweiligen Bandabschnitt selbst vorgesehene Werbeanzeige oder die als separate Werbeanzeige auf dem Bandabschnitt elastisch befestigte Anzeige ungestört betrachtbar ist, wenn der jeweilige Bandabschnitt für einen vorgebbaren Zeitraum zwischen den Rollen/Umlenkrolle(n) angehalten wird.With the image changing devices according to the invention, it is now possible that, depending on the number of pulleys to be used, at least two visible areas are formed on which, if necessary, different posters, advertising material or the like can be viewed. By use At least one, preferably designed as a helical spring in the range of one of the rollers can be compensated at the same speed of the drive shafts when winding and unwinding of the roll on the rollers adjusting different peripheral speeds of the winding. At the same time, due to the bias of the spring, the band portion between the rolling roller and the guide roller or the guide roller and the other roll on tight, so that the provided on the respective tape section self-advertisement or as a separate advertisement on the tape section elastically mounted display is undisturbed viewable when the respective band section for a predetermined period between the rollers / guide roller (s) is stopped.

Der jeweilige elektrische Antriebsmotor der beiden Rollen mit gleicher Drehzahl kann vorzugsweise dadurch erfolgen, daß entweder auf der Antriebswelle einer der Rollen ein Motor, vorzugsweise ein Getriebemotor, angeordnet ist und die beiden Wellen über ein umlaufendes Antriebsglied, insbesondere einen Zahnriemen, miteinander gekoppelt sind. Alternativ besteht auch die Möglichkeit, den oder die elektrischen Antriebsmotor(en) im Bereich zwischen den Rollen vorzusehen und die umlaufenden Antriebsmittel, wie Zahnriemen oder dergleichen, in Richtung der beiden Antriebswellen der Rollen zu führen.The respective electric drive motor of the two rollers at the same speed can preferably take place in that either a motor, preferably a geared motor, is arranged on the drive shaft of one of the rollers and the two shafts are coupled to one another via a revolving drive member, in particular a toothed belt. Alternatively, it is also possible to provide the electric drive motor (s) in the region between the rollers and to guide the revolving drive means, such as toothed belts or the like, in the direction of the two drive shafts of the rollers.

Die erfindungsgemäße Bildwechseleinrichtung ermöglicht nun folgende alternative Ausgestaltungen:The image changing device according to the invention now makes possible the following alternative embodiments:

Bei Einsatz lediglich einer Umlenkrolle und Betrachtung der Plakate oder sonstigen Werbemittel von zwei unterschiedlichen Seiten werden die beiden Rollen mit größerem Abstand zueinander vorsehbar und die Umlenkrolle unter Bildung eines gedachten, insbesondere gleichschenkligen Dreieckes zwischen den Rollen aufgenommen.When using only one pulley and viewing the posters or other advertising material from two different sides, the two roles with each other at a greater distance vorsehbar and the pulley taken to form an imaginary, in particular isosceles triangle between the rollers.

Bei Einsatz mehrerer Umlenkrollen sowie Betrachtung der Plakate oder sonstigen Werbemittel von mehr als zwei Seiten wird vorgeschlagen, die beiden Rollen mit vorgebbarem Abstand zueinander zu positionieren und die Umlenkrollen unter Bildung polygonaler Eckpunkte mit ggf. unterschiedlichen Abständen unter Bildung mehreckiger, insbesondere rechtwinkliger oder quadratischer Flächen, zu den Rollen zu positionieren.When using multiple pulleys and viewing the posters or other advertising material of more than two pages is proposed, the two roles with predeterminable distance to each other to position and the pulleys to form polygonal corners with possibly different distances to form polygonal, in particular rectangular or square surfaces to position the rollers.

Alternativ besteht auch die Möglichkeit, bei Einsatz mehrerer Umlenkrollen sowie Betrachtung der Plakate oder sonstigen Werbemittel von mehr als zwei Seiten die beiden Rollen mit vorgebbarem Abstand zueinander zu positionieren und die Umlenkrollen unter Bildung polygonaler Eckpunkte mit von einem gedachten Zentrum ausgehenden im wesentlichen gleichem radialen Abstand unter Bildung einer gedachten etwa kreisförmigen Grundfläche zu den Rollen zu positionieren. Hierbei wird an eine Litfaßsäule gedacht, die für den Betrachter über einen vorgebbaren Umfangsbereich (mit Ausnahme des Bereiches, wo die beiden Rollen vorgesehen sind) einen größtmöglichen Betrachtungsbereich bietet.Alternatively, it is also possible, when using multiple pulleys and viewing the posters or other advertising material of more than two sides to position the two roles with predetermined distance to each other and the pulleys under formation of polygonal vertices with outgoing from an imaginary center substantially the same radial distance below Formation of an imaginary approximately circular base to position the rollers. In this case, an advertising pillar is thought of which offers the viewer the widest possible viewing area over a predeterminable circumferential area (with the exception of the area where the two rollers are provided).

Einem weiteren Gedanken der Erfindung gemäß, besteht die Vitrine aus Glas oder kratzfestem Kunststoff und kann, je nach räumlicher Anordnung, gegenüber dem Rahmen in horizontaler oder vertikaler Richtung zumindest partiell bewegbar ausgebildet sein. Wie bereits angesprochen, werden Bildwechseleinrichtungen vorteilhafterweise dort eingesetzt, wo ein größerer Publikumsverkehr ist. Dies können Flughäfen, Bahnhöfe, Hotels oder dergleichen sein, wo das Medium Werbung sinnvoll eingesetzt werden kann. Je nach räumlicher Situation und Anzahl der zur Betrachtung eingesetzten Seiten können somit unterschiedlichste Vitrinenbauformen und Positionen der Bildwechseleinrichtung gebildet werden.According to a further aspect of the invention, the display case is made of glass or scratch-resistant plastic and, depending on the spatial arrangement, can be designed to be at least partially movable relative to the frame in the horizontal or vertical direction. As already mentioned, image change devices are advantageously used where there is a large public traffic. These can be airports, railway stations, hotels or the like, where the medium of advertising can be used meaningfully. Depending on the spatial situation and the number of pages used for viewing, it is thus possible to form a wide variety of display cabinet designs and positions of the picture changing device.

Der Erfindungsgegenstand ist anhand von Prinzipskizzen in der Zeichnung dargestellt und wird wie folgt beschrieben. Es zeigen:

Figuren 1 bis 3
Unterschiedlich gestaltete erfindungsgemäße Bildwechseleinrichtungen mit zwei und mehr sichtbaren Bereichen.
The subject invention is illustrated by schematic diagrams in the drawing and will be described as follows. Show it:
FIGS. 1 to 3
Differently designed picture changing devices according to the invention with two and more visible areas.

Die Figuren 1 bis 3 zeigen unterschiedliche Bildwechseleinrichtungen 1, die als gleiche Bauteile zwei Rollen 2,3 sowie mindestens eine Umlenkrolle 4 beinhalten. Die Figuren 1 bis 3 stellen Prinzipskizzen dar, wobei selbige nicht abschließend die Gestaltungsmöglichkeiten des Erfindungsgegenstandes widerspiegeln, vielmehr nur einzelne Ausführungsvarianten sind. Die Rollen 2,3 bilden Auf- bzw. Abwickelbereiche und wirken in diesem Beispiel mit einem einzelnen elektrischen Antriebsmotor 5 zusammen. Der Antriebsmotor 5 ist über Zahnriemen 6 mit der jeweiligen Rolle 2,3 verbunden.The FIGS. 1 to 3 show different image changing devices 1, which include two rollers 2,3 and at least one guide roller 4 as the same components. The FIGS. 1 to 3 represent schematic diagrams, which selbige not reflect the design possibilities of the subject invention, but only individual variants are. The rollers 2, 3 form winding and unwinding areas and cooperate in this example with a single electric drive motor 5. The drive motor 5 is connected via toothed belt 6 with the respective roller 2,3.

Vom Schutzumfang mit umfasst ist auch die Anordnung mehrerer Antriebsmotoren im Bereich der Rollen 2,3.The scope of protection also includes the arrangement of several drive motors in the region of the rollers 2, 3.

Die eine Rolle 2 ist als starre Rolle ausgebildet, während die andere Rolle 3 mit einer vorgespannten Schraubenfeder 7 zusammenwirkt, durch welche eine definierte Vorspannung für das umlaufende Band 8 realisierbar ist. Durch das Halten des Bandes 8 einerseits zwischen der Rolle 2 und der Umlenkrolle 4 und andererseits zwischen der Umlenkrolle 4 und der anderen Rolle 3 unter der federelastischen Vorspannung der Feder 7 können die sich bei gleicher Drehzahl der Rollen beim Auf- und Abrollen des Wickels auf den Rollen 2,3 einstellenden unterschiedlichen Umfangsgeschwindigkeiten der Wickel bei Einsatz des Antriebmotors 5 kompensiert werden. Gleichzeitig wird das Band 8 straff gehalten, so daß die auf den Bandabschnitten 9,10,11,12 vorhandenen Plakate, Werbemittel oder dergleichen ungestört betrachtbar sind, wenn der jeweilige Bandabschnitt 9,10,11,12 für einen vorgebbaren Zeitraum einerseits zwischen den Rollen 2 und der jeweiligen Umlenkrolle 4 und andererseits zwischen der jeweiligen Umlenkrolle 4 und den Rollen 3, respektive den jeweiligen Umlenkrollen 4, angehalten wird.The one roller 2 is formed as a rigid roller, while the other roller 3 cooperates with a prestressed coil spring 7, through which a defined bias for the circulating belt 8 can be realized. By holding the belt 8 on the one hand between the roller 2 and the guide roller 4 and on the other hand between the guide roller 4 and the other roller 3 under the resilient bias of the spring 7 which can be at the same speed of the rollers during winding and unwinding of the roll on the Rolls 2.3 adjusting different peripheral speeds of the winding when using the drive motor 5 can be compensated. At the same time the tape 8 is kept taut, so that the existing on the tape sections 9,10,11,12 posters, advertising or the like are undisturbed viewable if the respective band section 9,10,11,12 for a predetermined period of time, on the one hand between the rollers 2 and the respective guide roller 4 and on the other hand between the respective guide roller 4 and the rollers 3, respectively the respective guide rollers 4, is stopped.

Die Figuren 1 bis 3 zeigen verschiedene geometrische Anordnungen einerseits der Rollen 2,3 und andererseits der Umlenkrolle (n) 4.The FIGS. 1 to 3 show various geometric arrangements on the one hand, the rollers 2,3 and on the other hand, the guide roller (s) 4th

Gemäß Figur 1 ist eine um eine Ecke 19 führbare Bildwechseleinrichtung 1 beispielsweise an Wandbereichen 20,21 der Ecke 19 positioniert. Die sichtbaren Bandabschnitte 9,10 sind 90° versetzt zueinander vorgesehen. Die die Antriebswellen, respektive die Umlenkwelle bildenden Mittelpunkte 13,14,15 ergeben durch Verbindung der Mittelpunkte 13 bis 15 ein gedachtes gleichschenkliges Dreieck 22. Der elektrische Antriebsmotor 5 wirkt in diesem Beispiel über Zahnriemen 6 lediglich auf die Antriebswelle 13 der Rolle 2 ein, während das vorgespannte Federelement 7 in Form einer Schraubenfeder im Bereich der Rolle 3 positioniert ist. Die Vitrine 23 ist in diesem Beispiel ebenfalls rechtwinklig ausgebildet und bedarfsweise mit ausschwenkbaren Türen versehen.According to FIG. 1 For example, an image changing device 1 that can be guided around a corner 19 is positioned on wall regions 20, 21 of the corner 19. The visible Band sections 9,10 are 90 ° offset from each other. By connecting the center points 13 to 15, the center shafts 13, 14, 15 that form the drive shafts and / or the deflecting shaft produce an imaginary isosceles triangle 22. In this example, the electric drive motor 5 only acts on the drive shaft 13 of the roller 2 via toothed belt 6 the prestressed spring element 7 is positioned in the form of a helical spring in the region of the roller 3. The display case 23 is also formed at right angles in this example and if necessary provided with swing doors.

In Figur 2 ist eine im wesentlichen rechtwinklige Vitrine 24 dargestellt, bei welcher drei sichtbare Bildabschnitte 9,10,11 gebildet werden. Das Band 8 läuft hierbei um zwei mit Abstand zueinander vorgesehene (nicht sichtbare) Umlenkrollen 4 herum und wird im Bereich der dazu ebenfalls mit Abstand vorgesehenen (nicht sichtbaren) Rollen 2,3 auf- bzw. abgewickelt. Funktion und Arbeitsweise der in Figur 2 dargestellten Bildwechseleinrichtung 1 entspricht denjenigen der Figur 1.In FIG. 2 a substantially rectangular display case 24 is shown, in which three visible image sections 9,10,11 are formed. The belt 8 runs around two spaced apart (not visible) pulleys 4 around and is in the range of this also provided at a distance (not visible) rollers 2.3 up or unwound. Function and operation of in FIG. 2 displayed image changing device 1 corresponds to those of FIG. 1 ,

Figur 3 zeigt eine weitere Alternative. Nach Art einer Litfaßsäule beinhaltet die Bildwechseleinrichtung 1 Rollen 2,3 sowie drei Umlenkrollen 4, wodurch vier sichtbare Bildabschnitte 9, 10, 11, 12 gebildet werden. Durch Erhöhung der Anzahl der Umlenkrollen 4 können bedarfsweise weitere sichtbare Bereiche gebildet werden. Die Rollen 2,3 sowie die Umlenkrollen 4 sind in diesem Beispiel auf dem gleichen Radius angeordnet, so daß eine gedachte kreisförmige Grundfläche gebildet wird. Die Vitrine selber ist mit dem Bezugszeichen 25 versehen und umschließt die Rollen 2,3 sowie die Umlenkrollen 4, wobei die Rollen 2,3 nicht sichtbar sind. FIG. 3 shows another alternative. In the manner of an advertising column, the image changing device 1 includes rolls 2, 3 and three deflection rolls 4, whereby four visible image sections 9, 10, 11, 12 are formed. By increasing the number of pulleys 4, if necessary, further visible areas can be formed. The rollers 2,3 and the guide rollers 4 are arranged in this example on the same radius, so that an imaginary circular base is formed. The display case itself is provided with the reference numeral 25 and encloses the rollers 2,3 and the guide rollers 4, wherein the rollers 2,3 are not visible.

Alternativ besteht - je nach räumlicher Beschaffenheit - auch die Möglichkeit, die Bildwechseleinrichtung an Wandbereichen zu verankern oder aber selbige an einem mit einem Deckenbereich verbundenen Traggerüst vorzusehen.Alternatively, depending on the spatial condition, it is also possible to anchor the image changing device to wall areas or to provide the same on a support frame connected to a ceiling area.
