Abstract

On the central structure of a merry-go-round, bracket arms are arranged rotatably and drivably in the shape of a star around a central axis. On the free ends of the bracket arms, there hang passenger carriers. By means of an excentric device, the connecting rods of which are articulated on the one hand on the excentric device and on the other hand on the bracket arms, the bracket arms, with the passenger carriers, can be pivoted in alternating high and inclined positions about axes tangential to the central axis. The excentric device has, below the bracket arms, two turntables arranged coaxially above one another and concentrically with the central axis, which are rotatable about the central axis together and independently of the bracket arms, the upper turntable being pivotable into an inclined position relative to the lower turntable. The connecting rods are articulated on a catch ring which is supported coaxially on the upper turntable and is mounted freely rotatably. <IMAGE>

Description

Die Erfindung betrifft ein Rundfahrgeschäft mit einem Zentralbau, an dem sternfömig um eine Zentralachse dreh- sowie antreibbar Auslegerarme angeordnet sind, an deren freien Enden Fahrgastträger hängen, und der eine Exzentereinrichtung mit Zugstangen aufweist, welche an den Auslegerarmen angelenkt sind und diese mit den Fahrgastträgern um zur Zentralachse tangen­tiale Achsen in wechselnde Hoch- und Schräglagen schwenken.The invention relates to a circular ride with a central structure, on which star arms can be rotated and driven in a star-shaped manner about a central axis, on the free ends of which passenger carriers hang, and which has an eccentric device with tie rods which are articulated on the boom arms and these move around with the passenger carriers Swing the tangential axes to the central axis in alternating high and sloping positions.

Rundfahrgeschäfte der eingangs genannten Art mit einer Exzentereinrichtung sind beispielsweise unter den Be­zeichnungen "Polyp", "Krake" oder "Monster" bekannt. Ihre am Umfang des Zentralbaus um zur Zentralachse tangentiale Achsen schwenkbaren Auslegerarme rotieren im Betrieb um die Zentralachse. Dabei schwenken die Auslegerarme unter der Wirkung der Exzentereinrichtung und der zugeordneten Zugstangen um ihre Anlenkachsen in wechselnde Hoch- und Schräglagen.Circular rides of the type mentioned at the outset with an eccentric device are known, for example, by the names "Polyp", "Kraken" or "Monster". Its cantilever arms, which are pivotable on the circumference of the central structure about axes tangential to the central axis, rotate about the central axis during operation. Under the action of the eccentric device and the associated tie rods, the outrigger arms swivel around their articulation axes into alternating high and sloping positions.

Die Exzentereinrichtung des aus dem DE-U-1 956 873 bekannten Rundfahrgeschäfts besteht aus einer konzen­trisch zur Zentralachse im oberen Bereich des Zentral­baus angeordneten Drehscheibe, an deren Umfang - also exzentrisch zur Zentralachse - das eine Ende der jedem Auslegerarm zugeordneten Zugstange drehbar angelenkt ist. Das andere Ende jeder Zugstange ist mit dem zuge­ordneten Auslegerarm um eine ebenfalls zur Zentral­achse tangentiale Achse schwenkbar verbunden. Zum Betrieb der Exzentereinrichtung wird die Drehscheibe und/oder der dreh- und antreibbare Teil des Zentral­baus in Drehung versetzt. Der relative Unterschied der Drehgeschwindigkeit einerseits des Zentralbaus mit den Auslegern, andererseits der Exzentereinrichtung um die Mittelachse bestimmt dabei die Frequenz der Ausleger-­Schwenkbewegungen.The eccentric device of the round-trip business known from DE-U-1 956 873 consists of a turntable arranged concentrically to the central axis in the upper area of the central building, on the circumference of which - that is to say eccentrically to the central axis - the one end of the pull rod assigned to each extension arm is pivoted. The other end of each tie rod is pivotally connected to the associated extension arm about an axis which is also tangential to the central axis. The turntable is used to operate the eccentric device and / or the rotatable and drivable part of the central structure is rotated. The relative difference in the rotational speed on the one hand of the central building with the cantilevers and on the other hand of the eccentric device about the central axis determines the frequency of the cantilever swivel movements.

Um bei diesem bekannten Fahrgeschäft den Fahrgast­wechsel zu bewerkstelligen, müssen die Gelenke der Zugstangen an einigen Auslegern verschoben werden, damit alle Fahrgastträger gleichzeitig abgesenkt sind. Alternativ kann auch vorgesehen sein, zu diesem Zweck die betreffenden Zugstangen zu verlängern. Beides be­dingt einen erheblichen, vor allem dezentralen appara­tiven Aufwand mit der entsprechenden Gefahr von Be­triebsstörungen.In order to effect the passenger change in this known ride, the joints of the pull rods on some brackets have to be moved so that all of the passenger carriers are lowered at the same time. Alternatively, provision can also be made to extend the relevant tie rods for this purpose. Both involve a considerable, especially decentralized, expenditure on equipment, with the corresponding risk of malfunctions.

Der Erfindung liegt die Aufgabe zugrunde, eine zen­trale Exzentereinrichtung anzugeben, die mit einer Betätigungseinrichtung auskommt, hohe Betriebssicher­heit aufweist und auf einfache Weise die Einstellung unterschiedlicher Exzentrizitäten erlaubt.The invention is based on the object of specifying a central eccentric device which manages with an actuating device, has high operational reliability and allows the setting of different eccentricities in a simple manner.

Diese Aufgabe wird bei einem Rundfahrgeschäft der eingangs angegebenen Art dadurch gelöst, daß die Exzentereinrichtung zwei koaxial übereinander und kon­zentrisch zur Zentralachse angeordnete Drehkränze auf­weist, die gemeinsam und unabhängig von den Ausleger­armen um die Zentralachse drehbar sind, und deren oberer Drehkranz in eine schräge Relativlage zum unte­ren Drehkranz schwenkbar ist, und daß die Zugstangen an einem Mitnehmerring angelenkt sind, der koaxial am oberen Drehkranz abgestützt und frei drehbar gelagert ist.This object is achieved in a circular ride of the type mentioned above in that the eccentric device has two rotating rings arranged coaxially one above the other and concentric to the central axis, which can be rotated together and independently of the cantilever arms about the central axis, and the upper rotating ring in an oblique relative position to the lower The slewing ring is pivotable, and that the tie rods are articulated on a driving ring which is supported coaxially on the upper slewing ring and is freely rotatable.

Ein großer Vorteil dieses Rundfahrgeschäfts liegt in den vielseitigen Möglichkeiten zur Erzeugung höhen- und geschwindigkeitsvariabler Taumelbewegungen des Mitnehmerrings und entsprechend unterschiedlichen Schaukelbewegungen der Fahrgastträger. Werden nämlich der obere und der untere Drehkranz beispielsweise mit gegenläufigem Drehsinn gedreht, lassen sich bereits mit relativ langsamen Drehzahlen relativ häufige Schaukelbewegungen der Fahrgastträger erzeugen. Hier­durch ist eine deutliche Steigerung des Fahrerlebnis­ses erzielbar.A great advantage of this tour business is the versatile options for generating variable-height and speed-wobbling movements of the driving ring and correspondingly different rocking movements of the passenger carriers. If, for example, the upper and lower slewing rings are rotated with opposite directions of rotation, relatively frequent rocking movements of the passenger carriers can be generated even at relatively slow speeds. This enables a significant increase in the driving experience.

Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben. So ist vorzugsweise vor­gesehen, daß der obere Drehkranz von einem Ständer, welcher auf dem unteren Drehkranz befestigt ist, um eine zur Zentralachse tangentiale Achse schwenkbar gelagert ist und dabei diametral zum Ständer eine aus einer Zylinder-Kolbenstangenanordnung bestehende Hub­einrichtung zwischen dem unteren und oberen Drehkranz angeordnet ist. Durch Betätigung der Hubeinrichtung, d. h. durch Aus- bzw. Einfahren ihrer Kolbenstange, ist die Amplitude der annähernd sinusförmigen Auf- und Abwärtsbewegungen aller Schwenkarme auf einfache Weise veränderbar; vor allem aber läßt sich konstruktiv die Achslage der Hubeinrichtung unabhängig von der Zug­stangenlagerung wählen, weil die Exzentereinrichtung unterhalb der Zugstangenanlenkung am Mitnehmerring angeordnet ist.Advantageous developments of the invention are specified in the subclaims. Thus, it is preferably provided that the upper slewing ring of a stand, which is fastened to the lower slewing ring, is pivotably mounted about an axis tangential to the central axis and, diametrically to the stator, a lifting device consisting of a cylinder-piston rod arrangement is arranged between the lower and upper slewing ring is. By operating the lifting device, d. H. by extending or retracting their piston rod, the amplitude of the approximately sinusoidal up and down movements of all swivel arms can be changed in a simple manner; Above all, however, the axial position of the lifting device can be chosen independently of the tie rod mounting, because the eccentric device is arranged below the tie rod linkage on the driving ring.

Im folgenden wird ein Ausführungsbeispiel der Erfin­dung anhand einer Zeichnung erläutert. Es zeigen:

  • Fig. 1 einen schematischen Querschnitt eines Rundfahr­geschäfts mit einem hochgeschwenkten Ausleger­arm und einem Auslegerarm in seiner unteren Stellung;
  • Fig. 2 eine schematische Seitenansicht des Zentralbaus des Rundfahrgeschäfts gemäß Fig. 1 im gleichen Betriebszustand, jedoch in vergrößertem Maß­stab; und
  • Fig. 3 eine der Fig. 2 entsprechende Darstellung in einem anderem Betriebszustand (Ein- bzw. Aus­stieg).
An exemplary embodiment of the invention is explained below with reference to a drawing. Show it:
  • Figure 1 is a schematic cross section of a roundabout with a swiveled boom and a boom in its lower position.
  • FIG. 2 shows a schematic side view of the central structure of the circular shop according to FIG. 1 in the same operating state, but on an enlarged scale; and
  • Fig. 3 is a representation corresponding to FIG. 2 in a different operating state (entry or exit).

Fig. 1 zeigt schematisch ein Rundfahrgeschäft, auf dessen Grundgestell 1 ein um die Zentralachse 4 dreh­barer Zentralbau 2 angeordnet ist, von dessen oberem Ende sich Auslegerarme 6 radial auswärts erstrecken. Die Auslegerarme 6 sind bei diesem Ausführungsbeispiel geteilt und bestehen jeweils aus einem starr mit dem Zentralbau 2 verbundenen Tragarm 6a, an dem (radial auswärts) ein Schwenkarm 6b um die - zur Zentralachse 4 tangentiale - Achse 14 schwenkbar angelenkt ist. Die Zugstangen 12 sind einerseits bei 15 an den Schwenkar­men 6b, andererseits an der Exzentereinrichtung 10, und zwar deren Mitnehmerring 28 schwenkbar angelenkt; letzterer wird nachstehend noch näher beschrieben.1 schematically shows a circular ride, on the base frame 1 of which a central structure 2 rotatable about the central axis 4 is arranged, from the upper end of which extension arms 6 extend radially outward. The cantilever arms 6 are divided in this embodiment and each consist of a support arm 6a rigidly connected to the central structure 2, on which (radially outward) a swivel arm 6b is pivotally articulated about the axis 14, which is tangential to the central axis 4. The tie rods 12 are articulated on the one hand at 15 on the swivel arms 6b, on the other hand on the eccentric device 10, namely their driving ring 28; the latter is described in more detail below.

An den freien Enden der Schwenkarme 6b sind Tragwerke in Form von Satellitenkreuzen 5 um ihre Mittelachse 11 drehbar angeordnet. Der elektromotorische Antrieb 13 ist in Form der Nabe des Satellitenkreuzes 5 nur angedeutet. Die Arme 3 des Satellitenkreuzes 5 enden in Tragstücken 7 für die Schwenkachsen 9, um die drehbar die Fahrgastträger 8 mittels Tragarmen 8a und daran wiederum befestigten Naben 8b angehängt sind. Die Schrägstellung der Achsen 9 gegenüber der Haupt­ebene des Satellitenkreuzes 5, aufgrund derer die Schwenkachsen 9 gewissermaßen mit der Oberseite der Arme 3 spitze Winkel einschließen, ist in der Zeich­nung deutlich erkennbar. Der Sicherheit der Fahrgäste beim Betrieb des Rundfahrgeschäftes dienen Rückhalte­bügel 8c in den Fahrgastträgern 8.Structural structures in the form of satellite crosses 5 are arranged rotatably about their central axis 11 at the free ends of the swivel arms 6b. The electromotive drive 13 is only indicated in the form of the hub of the satellite cross 5. The arms 3 of the satellite cross 5 end in support pieces 7 for the pivot axes 9 to the passenger carriers 8 are rotatably attached by means of support arms 8a and hubs 8b which are in turn fastened thereon. The inclination of the axes 9 with respect to the main plane of the satellite cross 5, on the basis of which the pivot axes 9, as it were, enclose acute angles with the top of the arms 3, can be clearly seen in the drawing. Restraint bars 8c in the passenger carriers 8 serve to ensure the safety of the passengers when operating the circular shop.

Der Aufbau und die Wirkungsweise der Exzentereinrich­tung 10 sowie die Anlenkung der Zugstangen 12 einer­seits an der Exzentereinrichtung 10, andererseits an den Schwenkarmen 6b (bei 15) ist den Fig. 2 und 3 zu entnehmen. Dabei zeigt Fig. 2 die Exzentereinrichtung 10 in ihrer (äußersten) Arbeitsstellung, in welcher die Schwenkarme 6b mit den daran hängenden Fahrgast­trägern 8 abwechselnd hoch- und zurückgeschwenkt wer­den, während Fig. 3 die Ruhestellung der Exzenterein­richtung 10 veranschaulicht, in welcher alle Fahrgast­träger 8 diejenige Position einnehmen, in der die Fahrgäste ein- und aussteigen können.The structure and the mode of operation of the eccentric device 10 and the articulation of the tie rods 12 on the one hand on the eccentric device 10 and on the other hand on the swivel arms 6b (at 15) can be seen in FIGS. 2 and 3. 2 shows the eccentric device 10 in its (outermost) working position, in which the swivel arms 6b with the attached passenger carriers 8 are swiveled up and back alternately, while FIG. 3 illustrates the rest position of the eccentric device 10, in which all the passenger carriers 8 are Take a position where passengers can get on and off.

Der Zentralbau 2 weist eine Säule 2a auf, die sich auf einer Kugeldrehverbindung 38 um die Zentralachse 4 drehbar abstützt. Mit dem Zahnkranz 39 der Kugeldreh­verbindung 38 kämmt ein Ritzel 30, welches über ein Vorgelege 31 und einen Riementrieb 32 von einem Elek­tromotor 33 antreibbar ist.The central building 2 has a column 2a, which is supported on a rotary ball joint 38 so as to be rotatable about the central axis 4. A pinion 30 meshes with the ring gear 39 of the ball slewing ring 38, which pinion can be driven by an electric motor 33 via a countershaft 31 and a belt drive 32.

Konzentrisch zur Säule 2a und der Zentralachse 4 ist ein Drehkranz 16 angeordnet und auf einer Kugeldreh­verbindung 40 (unabhängig von der Säule 2a) um die Zentralachse 4 drehbar gelagert. Der feste Teil der Kugeldrehverbindung 40 stützt sich ebenso wie der feste Teil der Kugeldrehverbindung 38 auf der Grund­platte 1 ab. Ein Elektromotor 37 kann über Riemen 36 und ein Vorgelege 35 ein Ritzel 34 antreiben, welches mit der Außenverzahnung 42 der Kugeldrehverbindung 40 kämmt und den Drehkranz 16 um die Zentralachse 4 dreht.A turntable 16 is arranged concentrically to the column 2a and the central axis 4 and is rotatably mounted about the central axis 4 on a rotary ball joint 40 (independently of the column 2a). The fixed part of the ball slewing bearing 40 is supported as well fixed part of the ball slewing ring 38 on the base plate 1. An electric motor 37 can drive a pinion 34 via belts 36 and a countershaft 35, which meshes with the external toothing 42 of the ball slewing ring 40 and rotates the slewing ring 16 about the central axis 4.

Am Drehkranz 16 ist - mit Hilfe hier nicht interessie­render Bauteile - die Kolbenstange 26 eines Hydraulik­zylinders 24 um die zur Zentralachse 4 tangentiale Achse 25 schwenkbar angebracht. Der Zylinder 24 ist um eine zur Achse 25 parallele Achse 27 an einem weiteren Drehkranz 18 schwenkbar gelagert. Außer durch den Hy­draulikzylinder 24 mit der Kolbenstange 26 sind die Drehkränze 14, 18 noch durch einen Ständer 20 verbund­en, der diametral zur Kolbenstange 26 des Hydraulikzy­linders 24 am Drehkranz 16 befestigt ist und am ande­ren Ende einen radialen Ansatz 44 am Drehkranz 18 um die Achse 22 schwenkbar lagert. Die Achse 22 verläuft parallel zu den übereinander angeordneten Achsen 25 und 27, in bezug auf die Drehkränze 16 und 18 aber um 180° versetzt. Somit kann der Drehkranz 18 bei Betäti­gung des Hydraulikzylinders 24 die den Fig. 2 und 3 entnehmbare einseitige Hubbewegung ausführen.The piston rod 26 of a hydraulic cylinder 24 is mounted on the slewing ring 16 with the aid of components not of interest here, about the axis 25 tangential to the central axis 4. The cylinder 24 is pivotally mounted about an axis 27 parallel to the axis 25 on a further slewing ring 18. In addition to the hydraulic cylinder 24 with the piston rod 26, the turntables 14, 18 are also connected by a stand 20 which is attached diametrically to the piston rod 26 of the hydraulic cylinder 24 on the turntable 16 and at the other end a radial shoulder 44 on the turntable 18 about the axis 22 pivotally mounted. The axis 22 runs parallel to the superimposed axes 25 and 27, but offset by 180 ° with respect to the slewing rings 16 and 18. Thus, when the hydraulic cylinder 24 is actuated, the turntable 18 can execute the one-sided lifting movement which can be seen in FIGS. 2 and 3.

Der bereits oben erwähnte Mitnehmerring 28, welcher in seiner Konstruktion den Drehkränzen 16 und 18 ent­spricht, stützt sich über eine Kugeldrehverbindung 46 auf dem Drehkranz 18 - um die Zentralachse 4 frei drehbar - ab. Radial auswärts und am Umfang verteilt sind mit Hilfe von Böcken 48 die dem Zentralbau 2 zu­gewandten Enden der Zugstangen 12 um - wiederum zur Zentralachse 4 tangentiale - Achsen 50 schwenkbar ge­lagert. Die anderen Enden der Zugstangen 12 sind mit den Achsen 15 an den Schwenkarmen 6b angelenkt.The above-mentioned driving ring 28, which corresponds in its construction to the slewing rings 16 and 18, is supported on the slewing ring 18 via a ball slewing ring 46 — freely rotatable about the central axis 4. Radially outwards and distributed around the circumference, the ends of the tie rods 12 facing the central building 2 are pivotally supported by axles 50 — again tangential to the central axis 4 — axes 50. The other ends of the tie rods 12 are articulated with the axes 15 on the swivel arms 6b.

Wenn der Motor 33 über das Vorgelege 31 und das Ritzel 30 die Säule 2a in Rotation versetzt, dann nehmen die daran befestigten Tragarme 6a die Schwenkarme 6b sowie über die Zugstangen 12 auch den Mitnehmerring 28 mit. Diese Rotation des Mitnehmerringes 28 ist unabhängig davon, ob auch die Drehkränze 16 und 18 rotieren oder - sofern sie dies tun - auch deren Drehzahl um die Zentralachse 4 dieselbe oder eine andere ist. Denn die Kugeldrehverbindung 46 läßt eine Relativdrehung zu.If the motor 33 sets the column 2a in rotation via the reduction gear 31 and the pinion 30, the support arms 6a fastened thereon take the swivel arms 6b and also the driving ring 28 via the tie rods 12. This rotation of the driving ring 28 is independent of whether the slewing rings 16 and 18 also rotate or - if they do so - their speed about the central axis 4 is the same or a different one. Because the ball slewing ring 46 allows a relative rotation.

Entsprechend umgekehrt unabhängig kann der Elektromo­tor 37 das Ritzel 34 und damit den Drehkranz 16 an­treiben. Rotiert der Drehkranz 16 um die Zentralachse 4, so nimmt er infolge der Verbindung einerseits durch den Ständer 20, andererseits durch den Hydraulikzylin­der 24 mit der Kolbenstange 26 auch den Drehkranz 18 mit.Accordingly, vice versa, the electric motor 37 can drive the pinion 34 and thus the slewing ring 16. If the slewing ring 16 rotates about the central axis 4, it also takes along the slewing ring 18 as a result of the connection, on the one hand, through the stand 20 and, on the other hand, through the hydraulic cylinder 24 with the piston rod 26.

Nehmen die Drehkränze 16, 18 ihre in Fig. 3 darge­stellte Relativstellung (parallel zueinander) ein, so befinden sich alle Schwenkarme 6b und damit auch alle Satellitenkreuze 5 in ihrer tiefsten (abgesenkten) La­ge, in der die Fahrgastträger 8 von den Fahrgästen be­treten bzw. verlassen werden können. Wird jedoch der Hydraulikzylinder 24 betätigt, was im dargestellten Beispiel zu einem Einfahren der Kolbenstange 26 führt, so schwenkt gemäß Fig. 2 der obere Drehkranz 18 um die Achse 22 in eine Schräglage. Dabei nimmt er den Mit­nehmerring 28 in eine parallele Schräglage mit. Dies führt dazu, daß mit Ausnahme jeweils derjenigen Zug­stange 12, welche sich gerade oberhalb der Schwenk­achse 22 des Drehkranzes 18 befindet, alle anderen Zugstangen 12 nach unten gezogen werden und dement­sprechend ihre Schwenkarme 6b hochschwenken, wie dies in Fig. 1 und 2 links erkennbar ist. Wird dabei die Säule 2a vom Motor 33 über die oben beschriebene An­triebsverbindung in Drehung versetzt, so durchläuft periodisch jede Zugstange 12 die beiden in Fig. 2 dar­gestellten Extremstellungen sowie jede Zwischenstel­lung, was zu dem gewünschten Auf- und Abschwenken der Schwenkarme 6b mit den Satellitenkreuzen 5 führt.If the turntables 16, 18 assume their relative position shown in FIG. 3 (parallel to one another), then all swivel arms 6b and thus also all satellite crosses 5 are in their deepest (lowered) position, in which the passenger carriers 8 are entered by the passengers or can be left. However, if the hydraulic cylinder 24 is actuated, which in the example shown leads to the piston rod 26 being retracted, the upper swivel ring 18 swivels about the axis 22 into an inclined position according to FIG. 2. He takes the driver ring 28 in a parallel inclined position. This leads to the fact that, with the exception of each pull rod 12, which is located just above the pivot axis 22 of the rotating ring 18, all other pull rods 12 are pulled down and accordingly pivot their pivot arms 6b, as can be seen on the left in FIGS. 1 and 2 . Will the Column 2a set in rotation by the motor 33 via the drive connection described above, each pull rod 12 periodically passes through the two extreme positions shown in FIG. 2 and each intermediate position, which leads to the desired pivoting of the swivel arms 6b with the satellite crosses 5.

Derselbe Effekt des Auf- und Abschwenkens der Satelli­tenkreuze 5 läßt sich ohne Drehung der Säule 2a in dem in Fig. 2 dargestellten abgesenkten Zustand der Exzen­tereinrichtung 10 auch erreichen, wenn mit Hilfe des Motors 37 der Drehkranz 16 angetrieben wird. Denn in der oben dargelegten Weise wird die Drehung des Dreh­kranzes 16 auf den Drehkranz 18 übertragen, der somit eine Taumelbewegung um die Zentralachse 4 ausführt. Diese Taumelbewegung muß der Mitnehmerring 28 mit­machen, und dabei durchläuft wiederum jede Zugstange 12 die in Fig. 2 gezeigten Endlagen sowie alle dazwi­schenliegenden Positionen. Im Ergebnis können also die Satellitenkreuze 5 geschaukelt werden, ohne daß sie sich in Umfangsrichtung bewegen. Nur der Vollständig­keit halber sei an dieser Stelle erwähnt, daß natür­lich auch eine Drehung des Zentralbaus und damit der Satellitenkreuze 5 ohne jene Schwenkbewegung erfolgen kann, wenn nämlich der Drehkranz 18 und damit der Mit­nehmerring ihre in Fig. 3 dargestellte Relativlage einnehmen, in der sich die Exzentereinrichtung 10 ge­wissermaßen in der Ruhestellung befindet.The same effect of pivoting the satellite crosses 5 up and down can also be achieved without rotating the column 2a in the lowered state of the eccentric device 10 shown in FIG. 2 if the turntable 16 is driven by means of the motor 37. Because in the manner set out above, the rotation of the slewing ring 16 is transmitted to the slewing ring 18, which thus executes a wobbling movement about the central axis 4. The wobble ring 28 has to take part in this wobbling movement, and in turn each pull rod 12 passes through the end positions shown in FIG. 2 and all positions in between. As a result, the satellite crosses 5 can be rocked without moving in the circumferential direction. For the sake of completeness, it should be mentioned at this point that, of course, the central building and thus the satellite crosses 5 can also be rotated without that pivoting movement, namely when the rotating ring 18 and thus the driving ring assume their relative position, shown in FIG. 3, in which the Eccentric device 10 is located in the rest position.

Selbstverständlich lassen sich die von den Elektromo­toren 33, 37 erzeugten Drehbewegungen einander über­lagern, und zwar namentlich mit gegenläufigem Dreh­sinn. Denn dann läßt sich mit relativ langsamen Dreh­zahlen eine relativ häufige und somit schnelle Schau­kelbewegung der Satellitenkreuze 5 erzeugen. Umgekehrt würden bei gleichsinnigem und gleichschnellem Antrieb beider Drehsysteme die Satellitenkreuze 5 selbst dann nicht auf- und abgeschwenkt werden, wenn der Drehkranz 18 und der Mitnehmerring 28 ihre in Fig. 2 dargestell­te Lage einnehmen, die Exzentereinrichtung 10 sich al­so in der (extremen) Arbeitsstellung befindet. Viel­mehr würden die ganz oder teilweise angehobenen Satel­litenkreuze 5 diese Relativlage ebenso wie das abge­senkte oder nur wenig angehobene Satellitenkreuz 5 un­geachtet der Drehung der Säule 2a um die Zentralachse 4 (und damit einer entsprechenden Drehung der Satelli­tenkreuze 5 um die Zentralachse 4) beibehalten.Of course, the rotary movements generated by the electric motors 33, 37 can be superimposed on one another, specifically with an opposite direction of rotation. Because then a relatively frequent and thus rapid rocking movement of the satellite crosses 5 can be generated with relatively slow speeds. Vice versa with the same direction and the same fast drive of both rotating systems, the satellite crosses 5 would not be swung up and down even if the rotating ring 18 and the driving ring 28 assume their position shown in FIG. 2, the eccentric device 10 is therefore in the (extreme) working position. Rather, the wholly or partially raised satellite crosses 5 would maintain this relative position, as would the lowered or only slightly raised satellite cross 5 regardless of the rotation of the column 2a about the central axis 4 (and thus a corresponding rotation of the satellite crosses 5 about the central axis 4).

Zugleich wird daraus deutlich, daß sich durch entspre­chende Änderungen der Drehsinne und der Drehzahlen so­wie der Ausfahrstellung der Kolbenstange 26 in bezug auf den Hydraulikzylinder 24 sehr unterschiedliche Be­wegungskombinationen erzielen lassen.At the same time, it is clear from this that very different combinations of movements can be achieved with corresponding changes in the direction of rotation and the speeds and the extended position of the piston rod 26 with respect to the hydraulic cylinder 24.

Die vorstehend beschriebene Anordnung hat den weiteren Vorteil, daß infolge der Positionierung der Hubein­richtung (Hydraulikzylinder 24, Kolbenstange 26) ei­nerseits und des Ständers 20 andererseits unterhalb der Achsen 50 der Zugstangen 12 die Lage der Hubein­richtung (d. h. die Achslage des Hydraulikzylinders 24 und der Kolbenstange 26) unabhängig von der Zugstan­genlagerung gewählt werden kann. Vorteilhaft haben die Achsen 22 und 50 gleichen Abstand von der Zentralachse 4, so daß die Hubbewegung des Drehkranzes 18 nur zum Hochschwenken (nicht auch teilweise zum Absenken) der Satellitenkreuze 5 führt.The arrangement described above has the further advantage that, due to the positioning of the lifting device (hydraulic cylinder 24, piston rod 26) on the one hand and the stator 20 on the other hand, the position of the lifting device (ie the axial position of the hydraulic cylinder 24 and the piston rod 26) below the axes 50 of the tie rods 12 ) can be selected independently of the tie rod mounting. The axes 22 and 50 advantageously have the same distance from the central axis 4, so that the lifting movement of the turntable 18 only leads to the pivoting up (not also partially lowering) of the satellite crosses 5.

Ferner werden durch jene Ausbildung der Exzenterein­richtung 10 annähernd sinusförmige Auf- und Abwärtsbe­wegungen der Schwenkarme 6b und damit der Satelliten­ kreuze 5 erzeugt, und für den Fahrbetrieb ist bedeut­sam, daß sich die Achsen 14, um welche die Schwenkarme 6b mit den Satellitenkreuzen 5 und den Fahrgastträgern 8 schwenken, oberhalb des Gesamtschwerpunkts der je­weils hochzuschwenkenden Last befindet, so daß bei drehendem Karussell die auf den Schwerpunkt wirkende Fliehkraft das Hochschwenken unterstützt und die Zug­stangen 12 sowie die mit ihr verbundene Exzenterein­richtung 10 entlastet.Furthermore, that configuration of the eccentric device 10 results in approximately sinusoidal upward and downward movements of the swivel arms 6b and thus of the satellites crosses 5 generated, and for the driving operation it is important that the axes 14, about which the swivel arms 6b with the satellite crosses 5 and the passenger carriers 8 pivot, are above the total center of gravity of the load to be swiveled up, so that when the carousel rotates, the center of gravity acting centrifugal force supports the swiveling up and relieves the tie rods 12 and the eccentric device 10 connected to them.
