Drehvorrichtung Rotating device
Technisches GebietTechnical field
Die vorliegende Erfindung betrifft eine Drehvorrichtung zur Anbringung an Kreuzungspunkten eines Forderschienensystems mit Transporteinheiten. Sie dient dazu, die Transport- einheiten den m einer beliebigen Richtung verlaufenden Forderschienen zuzuführen und dabei gleichzeitig die Zufuhrung von Strom und von Steuerimpulsen an die Transporteinheiten zu gewahrleisten. An den Transporteinheiten angebracht sind beispielsweise Beleuchtungskörper, die durch die Transport- einheiten mit Energie und allenfalls Steuersignalen versorgt werden und so die flexible und je nachdem sogar mobile Ausleuchtung eines Raumes, zum Beispiel eines Fernsehstudios, gewährleisten.The present invention relates to a rotating device for attachment to crossing points of a Ford rail system with transport units. It serves to feed the transport units to the Ford rails running in any direction and at the same time to ensure the supply of electricity and control pulses to the transport units. Attached to the transport units are, for example, lighting fixtures which are supplied with energy and possibly control signals by the transport units and thus ensure flexible and, depending on the case, even mobile illumination of a room, for example a television studio.

Gebrauchliche Beleuchtungsanlagen für Fernsehstudios, Theaterbuhnen oder dergleichen weisen beispielsweise Scheinwerfer auf, die an einem sich an der Decke befindenden Fόr- derschienensystem mit Drehscheiben angebracht und auf denUsual lighting systems for television studios, theater stages or the like have, for example, headlights which are attached to a conveyor rail system with turntables located on the ceiling and on which
Schienen manuell positioniert werden können. In regelmassigen Abstanden sind an der Decke Versorgungskasten angebracht, von denen aus ein einmal positionierter Scheinwerfer mit Strom und Steuerimpulsen versorgt werden kann. Eine solche Anord- nung bedingt aber eine relativ frühzeitige und manuelle Vorbereitung für einen Anlass, an dem die Beleuchtungsanlage zum Einsatz kommen soll, und erschwert das flexible, kurzfristige Anpassen der Beleuchtungssituation. Ein anderes System für eine Beleuchtungsanlage sieht das Anbringen einer Vielzahl von nur hohenverstellbaren Scheinwerfern vor, wobei e nach Bedarf die Scheinwerfer zum Ein- satz gebracht werden können, die sich an der passenden Stelle befinden. Dabei lasst sich lediglich die Hohe der Scheinwerfer beliebig wählen. Dieses System ermöglicht zwar ein flexibles Arbeiten, bedingt aber grosse Investitionen in teure Scheinwerferanlagen und schrankt die Anzahl Positionen, von denen aus ein Scheinwerfer zum Einsatz gebracht werden kann, betrachtlich ein.Rails can be positioned manually. At regular intervals there are supply boxes on the ceiling, from which a spotlight once positioned can be supplied with power and control pulses. However, such an arrangement requires a relatively early and manual preparation for an occasion on which the lighting system is to be used, and makes it difficult to adapt the lighting situation quickly and flexibly. Another system for a lighting system provides for the attachment of a large number of headlights which are only adjustable in height, it being possible for the headlights which are in the appropriate place to be used as required. Only the height of the headlights can be chosen arbitrarily. Although this system enables flexible working, it requires large investments in expensive headlamp systems and limits the number of positions from which a headlamp can be used considerably.
Ein wieder anderes System beruht auf einem Forderschienensystem, das in die Deckenkonstruktion eines Studios m- stalliert werden kann. So ein Forderschienensystem weistYet another system is based on a Ford rail system that can be installed in the ceiling structure of a studio. Such a Ford rail system points
Schienen auf, die zueinander parallel sind und über die ganze Lange des Bereichs verlaufen, m dem Scheinwerfer zum Einsatz kommen sollen. Auf einem Paar solcher Schienen sind jeweils mehrere Schienenabschnitte verschiebbar angebracht, deren Laufrichtung senkrecht zur Laufrichtung der Schienen verlauft. Die Scheinwerfer sind an Transporteinheiten befestigt, die auf den Schienenabschnitten verschoben werden können. Zwei Schienenabschnitte auf benachbarten Schienenpaaren können dann so in Position gebracht werden, dass sie miteinander fluchten und eine Transporteinheit eines Scheinwerfers von einem Schienenabschnitt zum nächsten verschoben werden kann. Auf diese Weise kann ein Scheinwerfer im Prinzip an jede gewünschte Position an der Decke gebracht werden. Eine solche Anlage hat aber den wesentlichen Nachteil, dass die Trans- portwege auf dem Schienensystem lang und umständlich werden, wenn das Beleuchtungssystem eine grossere Anzahl von Scheinwerfern aufweist, die möglicherweise noch verschiedener Machart sind und verschiedene Funktionen erfüllen, da mit Transporteinheiten besetzte Schienenabschnitte einander bei Posi- tionsanderungen behindern. Abriss der ErfindungRails that are parallel to each other and run the entire length of the area where the headlights are to be used. On a pair of such rails, several rail sections are slidably mounted, the running direction of which is perpendicular to the running direction of the rails. The headlights are attached to transport units that can be moved on the rail sections. Two rail sections on adjacent pairs of rails can then be brought into position so that they are aligned with one another and a transport unit of a headlight can be moved from one rail section to the next. In this way, a headlight can in principle be brought to any desired position on the ceiling. However, such a system has the major disadvantage that the transport routes on the rail system become long and cumbersome if the lighting system has a large number of headlights, which may still be of different designs and perform different functions, since rail sections occupied by transport units help each other Hinder position changes. Outline of the invention
Die Aufgabe der vorliegenden Erfindung ist, eine Beleuch- tungsanlage zu ermöglichen, die die Nachteile der vorstehend beschriebenen Anlagen nicht aufweist und bei der die Beleuchtungskörper auch dann flexibel verschoben werden können, wahrend sie im Einsatz sind.The object of the present invention is to enable a lighting system which does not have the disadvantages of the systems described above and in which the lighting elements can also be moved flexibly while they are in use.

Wie das in der Figur 1 dargestellt ist, besteht die Dreh- Vorrichtung aus zwei Bestandteilen, von denen der eine, als Ganzes mit 1 bezeichnete und fest an Kreuzungspunkten des Forderschienensystems zu installierende als Drehlager für den anderen, als Ganzes mit 2 bezeichneten, und im Folgenden Schienentrager genannten ausgebildet ist. Das Drehlager 1 besteht im Wesentlichen aus einem Hohlzy- lmder 11 mit einem Aussendurchmesser Da und einem Innendurchmesser D_ . Dieser ist mit Gewindelochern 12 versehen, an denen Befestigungsmittel angreifen können, um die Drehvor- richtung an einer Decke oder an einem Stangengerüst zu befestigen. Je nach dem Aufbau des Forderschienensystems sind am Zylinder 11 beispielsweise acht Schienenansatze 21, 22, 23, 24, 25, 26, 27, 28 von ortsfesten Forderschienen fixiert, die von der Zylmderoberflache radial nach aussen gefuhrt sind, wobei jeweils zwei benachbarte Ansätze einen Winkel von 45° zueinander aufweisen.As shown in Figure 1, the rotating device consists of two components, one of which, designated as a whole with 1 and to be installed permanently at intersection points of the Ford rail system, as a pivot bearing for the other, designated as a whole with 2, and in The following rail support is formed. The rotary bearing 1 essentially consists of a hollow cylinder 11 with an outer diameter D a and an inner diameter D_. This is provided with threaded holes 12, on which fasteners can engage in order to fasten the rotating device to a ceiling or to a bar frame. Depending on the structure of the Ford rail system, eight cylinder lugs 21, 22, 23, 24, 25, 26, 27, 28, for example, are fixed to the cylinder 11 by stationary Ford rails which are guided radially outward from the cylinder surface, two adjacent approaches at an angle of 45 ° to each other.
Der Schienentrager 2 besteht ebenfalls im Wesentlichen aus einem Hohlzylmder 50, dessen Aussendurchmesser da ein wenig kleiner ist als der Innendurchmesser D_ des zum Drehlager 1 zugehörigen Hohlzylmders 11. Er ist zusätzlich an der Oberseite mit einem Flansch 51 mit einem Aussendurchmesser d versehen, der mindestens gleich Da ist. Im unteren Teil des Schienentragers angebracht ist ein Schienenabschnitt 52, der m einer Diagonale des Zylinders 50 verlauft.The rail support 2 also essentially consists of a hollow cylinder 50, the outer diameter d a of which is slightly smaller than the inner diameter D_ of the hollow cylinder 11 associated with the rotary bearing 1. It is additionally provided on the top with a flange 51 with an outer diameter d of at least is equal to D a . In the lower part of the rail support, a rail section 52 is attached, which runs on a diagonal of the cylinder 50.
Jeder der Schienenansatze 21 bis 28 ebenso wie der Schienenabschnitt 52 sind spiegelsymmetrisch bez glich einer entlang der Schienenrichtung verlaufenden, im gezeichneten Bei- spiel vertikalen Ebene. Jeder Schienenansatz 21 bis 28 bzw. jeder Schienenabschnitt 52 weist eine Decke 31, zwei Seiten- wande 32, 33 und zwei Rollbahnen 34, 35 auf. Auf den Rollbahnen 34, 35 ist eine als Laufkatze ausgebildete Transporteinheit 70 entlang der Laufrichtung der Schiene verschiebbar. An beiden Seltenwanden 32, 33 der Schienen ist je ein Kunst- stoffband 36 angebracht. Jedes der Kunststoffbander ist mit mindestens zwei Rillen versehen, in denen sich e eine Stromschiene 37 bzw. 38 befindet, die auf die Innenseite der Schienen hm offenliegt und als Kontaktbahn dient. Die eman- der gegenüberliegenden Kontaktbahnen 37, 38 der Schienenan- Sätze 21 bis 28 sind über Verbindungen 46, 47 miteinander kontaktiert. Die Verbindungen 46, 47 können beispielsweise als an der Aussenseite der Schienenansätze 21 bis 28 angebrachte Stromleitungskabel ausgebildet sein, die die Kontakt- bahnen 37, 38 durch Öffnungen in den Seitenwänden 32, 33 kontaktieren.Each of the rail attachments 21 to 28 as well as the rail section 52 are mirror-symmetrical with respect to a plane which runs along the rail direction and is vertical in the example shown. Each rail attachment 21 to 28 or each rail section 52 has a ceiling 31, two side walls 32, 33 and two roller tracks 34, 35. A transport unit 70 designed as a trolley can be displaced along the running direction of the rail on the runways 34, 35. A plastic strip 36 is attached to each of the two rare walls 32, 33 of the rails. Each of the plastic strips is provided with at least two grooves, in which there is a busbar 37 or 38, which is exposed on the inside of the rails and serves as a contact track. The mutually opposite contact tracks 37, 38 of the rail Sets 21 to 28 are contacted with one another via connections 46, 47. The connections 46, 47 can be designed, for example, as power line cables attached to the outside of the rail extensions 21 to 28, which contact the contact tracks 37, 38 through openings in the side walls 32, 33.
Im Innern der Hohlzylinders 11 des Drehlagers 1 der Drehvorrichtung ist ebenfalls ein Kunststoffband 41 mit eingeleg- ten Stromschienen 42, 43 angebracht, die direkt mit denIn the interior of the hollow cylinder 11 of the rotary bearing 1 of the rotating device there is also a plastic band 41 with inserted busbars 42, 43, which directly with the
Stromschienen 37, 38 der Schienenansätze 21 bis 28 verbunden sind. Der Schienenträger 2 weist nun Kontaktstifte 44, 45 auf, die mit den Kontaktbahnen 37, 38 des Schienenabschnittes 52 verbunden sind und im betriebsbereiten Zustand beispiels- weise durch eine Feder auf die Stromschienen 42, 43 gedrückt werden, so dass sie diese elektrisch kontaktieren.Busbars 37, 38 of the rail lugs 21 to 28 are connected. The rail support 2 now has contact pins 44, 45 which are connected to the contact tracks 37, 38 of the rail section 52 and are pressed, for example by a spring, onto the busbars 42, 43 so that they make electrical contact with them.
Die in der Figur 4 schematisch dargestellte Laufkatze 70 weist mehrere Achsen mit auf den Rollbahnen 34, 35 abrollen- den Rädern 71 sowie Antriebsmittel auf, mit denen sie sich auf der Schiene fortbewegen kann. Auf der in der Figur 4 dem Betrachter zugewandten Seite der Laufkatze 70 sind Stromabnehmer 72 angebracht, die auf den Kontaktbahnen 37, 38 schleifen. Im in der Figur 2 gezeichneten Ausführungsbeispiel weist die Laufkatze 70 in der Fahrrichtung vorne und hinten je einen Satz Stromabnehmer auf, wobei entsprechend der Anzahl Kontaktbahnen 37, 38 lediglich zwei Stromabnehmer 72 pro Satz vorhanden ist. Die Anzahl der Stromabnehmer erhöht sich aber selbstverständlich mit der Anzahl Kontaktbahnen 37, 38, wenn mehr als zwei von diesen vorhanden sind. Zusätzlich weist die Laufkatze noch Räder 73 auf, die an ihrer Oberseite angebracht sind und die durch Abrollen an der Decke 31 verhindern, dass sich die Laufkatze 70 bei grossen Beschleunigungen aufrichten kann und dabei die Stromabnehmer den Kon- takt zu den Stromschienen 37, 38 verlieren. Im betriebsbereiten Zustand ist der Schienentrager 2, wie das in der Figur 1 dargestellt ist, in das Drehlager 1 der Drehvorrichtung eingebracht. Zwischen dem Flansch 51 und der Oberkante 11a des Zylinders 11 befindet sich ein Wälzlager 61, das ermöglicht, dass der Schienentrager 2 mit geringem Widerstand gegen das Drehlager 1 verdreht werden kann. Zu diesem Zweck weist der Schienentrager 2 einen Stellantrieb auf. Ein über Zuleitungen 62 mit den Stromschienen 37, 38 des Schienenabschnittes 52 verbundener Elektromotor 63 auf ist an der Innenseite des Schienentragers 2 befestigt. Dieser bewirkt bei Bedarf über ein Kunststoffzahnrad 64, das durch eine Öffnung 65 im Zylinder 50 in die Zahnung einer an der Innenwand des Zylinders 11 versenkt angebrachten Kunststoff- Zahnstange 66' eingreift, eine Drehung des Schienentragers. Zusatzlich sind an vorgegebenen, sich im Winkelabstand von 45° zueinander befindlichen Positionen auf der Innenseite des Hohlzylinders kugelförmige Vertiefungen 67 angebracht. Eine Kugel 68 ist auf der Aussenseite des Zylinders 50 angebracht und wird durch eine Feder gegen einen Anschlag beziehungsweise im betriebsbereiten Zustand gegen die Innenseite des Zylinders 11 nach aussen gedruckt. Sie rastet dann in eine dieser Vertiefungen ein, wenn der Schienentrager so ausgerichtet ist, dass sich einer der Schienenansatze 21 bis 28 in der Richtung befindet, die von seinem Schienenabschnitt 52 radial nach aussen fuhrt. Auf diese Weise werden die Positionen, in denen eine Transporteinheit auf den Schienentrager 2 oder von ihm weg gefahren werden kann, als fixe Positionen des Schienentragers 2 definiert.The trolley 70 shown schematically in FIG. 4 has several axes with wheels 71 rolling on the roller tracks 34, 35 as well as drive means with which it can move on the rail. On the side of the trolley 70 facing the viewer in FIG. 4, current collectors 72 are attached, which slide on the contact tracks 37, 38. In the exemplary embodiment shown in FIG. 2, the trolley 70 has one set of pantographs in the direction of travel, front and rear, with only two pantographs 72 per set corresponding to the number of contact tracks 37, 38. The number of current collectors naturally increases with the number of contact tracks 37, 38 if there are more than two of them. In addition, the trolley also has wheels 73, which are attached to its upper side and which, by rolling off the ceiling 31, prevent the trolley 70 from being able to stand up under high accelerations and the pantographs losing contact with the busbars 37, 38 . In the operational state, the rail support 2, as shown in FIG. 1, is inserted into the rotary bearing 1 of the rotating device. There is a roller bearing 61 between the flange 51 and the upper edge 11a of the cylinder 11, which enables the rail support 2 to be rotated with little resistance to the rotary bearing 1. For this purpose, the rail support 2 has an actuator. An electric motor 63 connected via leads 62 to the busbars 37, 38 of the rail section 52 is fastened to the inside of the rail carrier 2. If necessary, this causes the rail support to rotate via a plastic gear 64, which engages through an opening 65 in the cylinder 50 into the teeth of a plastic toothed rack 66 ' which is countersunk on the inner wall of the cylinder 11. In addition, spherical depressions 67 are provided at predetermined positions at an angular distance of 45 ° from one another on the inside of the hollow cylinder. A ball 68 is attached to the outside of the cylinder 50 and is pressed outwards by a spring against a stop or, in the operational state, against the inside of the cylinder 11. It then snaps into one of these recesses when the rail support is aligned such that one of the rail extensions 21 to 28 is in the direction which leads radially outward from its rail section 52. In this way, the positions in which a transport unit can be moved onto the rail support 2 or away from it are defined as fixed positions of the rail support 2.
Im Folgenden wird noch kurz der Aufbau und die Funktionsweise einer mit erfindungsgemassen Drehvorrichtungen versehenen Beleuchtungsanlage geschildert. In der Figur 5 ist eine Ansicht eines Teils einer solchen Beleuchtungsanlage mit ei- nem nur schematisch dargestellten Beleuchtungskörper 80 ge- zeigt. Der Beleuchtungskörper 80 ist beispielsweise ein Scheinwerfer mit einem Satz von Farbfiltern und einer Vorrichtung zum Einschieben eines Filters aus diesem Satz. Wie das für traditionelle Beleuchtungssysteme bekannt ist, ist er mit Mitteln versehen, mit denen seine Höhe verstellt werden kann und mit denen sein Licht m eine beliebige Richtung geworfen werden kann.The structure and the mode of operation of a lighting system provided with rotating devices according to the invention are briefly described below. FIG. 5 shows a view of part of such a lighting system with a lighting element 80 which is only shown schematically. shows. The lighting fixture 80 is, for example, a headlamp with a set of color filters and a device for inserting a filter from this set. As is known for traditional lighting systems, it is provided with means with which its height can be adjusted and with which its light can be thrown in any direction.
Die Scheinwerfer werden zusammen mit der Vorrichtung zum Einschieben der Farbfilter über die Kontaktbahnen via die Laufkatze 70 mit Strom versorgt. Zur Einspeisung von Strom und e nach dem von Steuersignalen in die Kontaktbahnen 37, 38, 42, 43 des Forderschienensystems wird eine der ortsfest installierten Schienen über Kabel kontaktiert, die mit Netz- und allenfalls Steuergeraten verbunden sind. Die Kontaktbahen 42, 43 des Drehlagers 1 sorgen zusammen mit den Verbindungen 46, 47, die die gegenüberliegenden Kontaktbahnen 37, 38 der ortsfesten Schienen miteinander kontaktieren, und mit den Verbindungen zu den Schienenabschnitten 52 der Schienentrager 2 über die Kontaktstifte 44, 45 dafür, dass das ganzeThe headlights, together with the device for inserting the color filters, are supplied with current via the contact tracks via the trolley 70. To feed current and e after the control signals into the contact tracks 37, 38, 42, 43 of the Ford rail system, one of the fixed rails is contacted via cables, which are connected to power supply units and possibly control devices. The contact tracks 42, 43 of the rotary bearing 1 together with the connections 46, 47, which contact the opposite contact tracks 37, 38 of the stationary rails, and with the connections to the rail sections 52 of the rail supports 2 via the contact pins 44, 45 ensure that the whole
Schienennetz standig mit Netz- und Steuergeraten verbunden ist, wobei bei grosseren Beleuchtungsanlagen je nach dem noch eine Unterteilung in Sektoren erfolgen kann, die jeweils eine getrennte Stromversorgung aufweisen. In diesem Fall wird die Laufkatze einer jeden Transporteinheit, so wie das in derRail network is constantly connected to power supply and control devices, with larger lighting systems depending on which can still be divided into sectors, each with a separate power supply. In this case, the trolley of each transport unit, like that in the
Figur 4 dargestellt ist, zwei in der Fahrrichtung hintereinander liegende Satze von Stromabnehmern und eine Relais- schaltung aufweisen, die zwischen den beiden Stromabnehmer- satzen hin- und herschaltet, damit nicht eine Laufkatze zwei Sektoren miteinander kurzschliessen kann.FIG. 4 is shown to have two sets of pantographs one behind the other in the direction of travel and a relay circuit that switches back and forth between the two pantograph sets so that a trolley cannot short-circuit two sectors with one another.
Die Beleuchtungsanlage weist auch eine in der Zeichnung nicht dargestellte zentrale Steuereinheit auf. Mit Hilfe dieser Steuereinheit können die Position und aktuelle Funktion eines jeden Scheinwerfers nach einem vorgegebenen Programm oder durch direkte Bedienung laufend den Erfordernissen ange- passt werden. Die Ansteuerung der Scheinwerfer, der Vorrichtungen zum Einschieben der Farbfilter, der Laufkatzen und der Stellantriebe durch die Steuereinheit erfolgt dann entweder über ein der Stromversorgung aufmoduliertes Steuersignal, über zusatzliche, in der Zeichnung nicht dargestellte und zu den gezeichneten Stromschienen 37, 38 parallele Kontaktbahnen zur Steuersignalubermittlung oder über eine Infrarotfernsteuerung.The lighting system also has a central control unit, not shown in the drawing. With the help of this control unit, the position and current function of each headlight according to a predetermined program or continuously adapted to requirements by direct operation. The control of the headlights, the devices for inserting the color filters, the trolleys and the actuators by the control unit then takes place either via a control signal modulated onto the power supply, via additional contact tracks (not shown in the drawing) and parallel to the drawn busbars 37, 38 for transmitting the control signal or via an infrared remote control.
Die lückenlose Strom- und Steuerimpulsversorgung der Scheinwerfer unabhängig von ihrer Position ermöglicht es, dass diese ihre Position auch wahrend der Benutzung verandern können, was neuartige und spektakuläre Lichteffekte bei Vor- fuhrungen, beispielsweise bei Rockkonzerten ermöglicht. Dadurch, dass die erflndungsgemässe Drehvorrichtung einen Stellantrieb mit einer gerauscharmen Kraftübertragung über ein Kunststoffzahnrad versehen ist, kann aber auch zum Beispiel in Fernsehstudios wahrend einer Sendung ein Beleuch- tungskorper ohne weiteres verschoben werden, was eine gros- sere Flexibilität im Vergleich zu herkömmlichen Beleuchtungsanlagen bewirkt und insbesondere ein Arbeiten mit weniger Scheinwerfern ermöglicht.The seamless supply of current and control pulses to the headlights, regardless of their position, enables them to change their position even during use, which enables novel and spectacular lighting effects during demonstrations, for example at rock concerts. Because the rotary device according to the invention is provided with an actuator with a low-noise power transmission via a plastic gearwheel, a lighting body can also be easily moved during a broadcast, for example in television studios, which results in greater flexibility compared to conventional lighting systems and in particular allows working with fewer headlights.
Abschliessend sei noch erwähnt, dass die vorstehend beschriebene Drehvorrichtung keinesfalls die einzige mögliche Ausfuhrungsform der Erfindung darstellt und noch in mancher Hinsicht geändert werden kann. So ist es zum Beispiel ohne weiteres denkbar, dass die ganze Stromversorgung auf der Ba- sis von Dreiphasenstrom funktioniert, in einem solchen Fall wurde sich die Anzahl der Kontaktbahnen 38, 39 naturlich entsprechend erhohen.Finally, it should be mentioned that the rotary device described above is by no means the only possible embodiment of the invention and can still be changed in some respects. For example, it is easily conceivable that the entire power supply works on the basis of three-phase current. In such a case, the number of contact tracks 38, 39 would of course be increased accordingly.
Es ist auch ohne weiteres möglich, dass ein Schienentra- ger 2 mehr als einen Schienenabschnitt 52 aufweist. Wenn zum 10It is also readily possible for a rail support 2 to have more than one rail section 52. If at 10
Beispiel zwei gekreuzte, in einem Winkel von 90° zueinander stehende Schienenabschnitte an jedem Schienentrager 2 angebracht sind, kann der maximale Winkel, um den der Schienentrager gedreht werden muss, bevor eine Transporteinheit 70 von einer vorgegebenen ortsfesten Schiene auf einen seiner Schienenabschnitte verschoben werden kann, auf 45° reduziert werden. Auf diese Weise kann je nach dem die Geschwindigkeit, mit der die Positionen der Transporteinheiten 70 angepasst werden können, zusatzlich erhöht werden.For example, two crossed rail sections, which are at an angle of 90 ° to one another, are attached to each rail support 2, the maximum angle by which the rail support must be rotated before a transport unit 70 can be moved from a predetermined fixed rail to one of its rail sections, can be reduced to 45 °. In this way, the speed at which the positions of the transport units 70 can be adjusted can additionally be increased.
Auch der Aufbau des Forderschienensystems kann sich selbstverständlich von dem in der Figur 5 schematisch dargestellten Ausfuhrungsbeispiel unterscheiden. Die Drehvorrichtungen können beispielsweise so installiert werden, dass eine Drehvorrichtung direkt an die nächste anschliesst, so dass die Transporteinheiten direkt von einem Schienentrager 2 zum nächsten gelangen könnte, ohne über fest installierte Schienen fahren zu müssen. In diesem Fall wurde das Drehlager 1 natürlich nicht acht Schienenansatze 21 bis 28 aufweisen, sondern beispielsweise nur deren vier, die in den diagonalen Richtungen des Fordersystems verlaufen würden.The structure of the Ford rail system can of course also differ from the exemplary embodiment shown schematically in FIG. The rotating devices can be installed, for example, in such a way that one rotating device connects directly to the next, so that the transport units could go directly from one rail support 2 to the next without having to travel over permanently installed rails. In this case, the pivot bearing 1 would of course not have eight rail extensions 21 to 28, but only four of them, for example, which would run in the diagonal directions of the front system.
Als Transporteinheiten kommen durchaus nicht nur Beleuchtungskörper in Frage. Auf einem mit den erfindungsgemassen Drehvorrichtungen versehenen Förderschienensystem können zum Beispiel durchaus auch Fernsehkameras, Lautsprecherboxen etc. für sich oder in Kombination mit Beleuchtungskörpern flexibel und mobil positioniert werden.Lighting units are not the only possible transport units. On a conveyor rail system provided with the rotating devices according to the invention, for example, television cameras, loudspeaker boxes, etc., can also be flexibly and mobilely positioned by themselves or in combination with lighting fixtures.
Die Drehvorrichtung eignet sich naturlich noch f r andere Anwendungen als für den Unterhaltungsbereich, zum Beispiel zur Verwendung für programmsteuerbare Transportvorrichtungen in einer Lagerhalle. The turning device is of course also suitable for applications other than for the entertainment area, for example for use for program-controlled transport devices in a warehouse.
