Description

Die Erfindung bezieht sich auf ein Karussell mit einem unteren, um eine vertikale Grundachse drehbar gelagerten Drehkranz, an dem in etwa radialer Richtung sich erstreckende, Fahrgastträger aufweisende Ausleger um horizontale Achsen schwenkbar gelagert sind, welche über radiale Zugstangen mit einem oberen Drehkranz gelenkig verbunden sind, der aus einer mit der Grundachse ungefähr übereinstimmenden unteren Stellung in eine angehobene, seitlich versetzte und schräg liegende obere Stellung motorisch bewegbar ist.The invention relates to a carousel with a lower turntable rotatably mounted about a vertical base axis, on which booms which extend in approximately the radial direction and have passenger carriers are pivotally mounted about horizontal axes and are articulated via radial tie rods to an upper turntable. which can be moved by motor from a lower position approximately coinciding with the basic axis into a raised, laterally offset and inclined upper position.

Karussells dieser Art sind durch die DE-A-16 03 173 und DE-A-22 06 339 bekannt. Im ersten Fall wird der Drehkranz, an dem die Zugstangen angelenkt sind, zunächst in einer mit der Hauptachse übereinstimmenden Richtung angehoben und dann mit Hilfe eines Zusatzgetriebes exzentrisch zur Grundachse in horizontaler Richtung verschoben. In einer Variante hierzu wird der obere Drehkranz längs einer schräg ansteigenden Säule höhenverstellbar geführt.Carousels of this type are known from DE-A-16 03 173 and DE-A-22 06 339. In the first case, the slewing ring on which the tie rods are articulated is first raised in a direction coinciding with the main axis and then moved eccentrically to the basic axis in the horizontal direction with the aid of an additional gear. In a variant of this, the upper swivel head is guided in a height-adjustable manner along a sloping column.

Diese Maßnahmen haben den Sinn, die an den Enden der Fahrgast-Ausleger befindlichen Fahrgastträger während der Rotation des Karussells eine Berg- und Tal-Kurvenbewegung ausführen zu lassen. Dabei ist aber eine vom Gebrauchszweck her vorbestimmte Bedingung zu erfüllen, wonach sämtliche Fahrgastträger in der Grundstellung des Karussells gleichzeitig bestiegen werden müssen. Diese Bedingung hat zur Folge, daß der obere Drehkranz in die angehobene Stellung bewegt werden muß, bevor das Karussell zu rotieren beginnt, um dadurch zu verhindern, daß die Fahrgastträger in eine tiefere als zum Einsteigen benötigte Lage beim Durchfahren des Tales der Berg- und Tal-Kurvenbahn gelangen können.The purpose of these measures is to have the passenger carriers located at the ends of the passenger booms perform a mountain and valley curve movement during the rotation of the carousel. In this case, however, a condition predetermined in terms of use must be met, according to which all the passenger carriers must be climbed in the basic position of the carousel at the same time. The result of this condition is that the upper slewing ring must be moved to the raised position before the carousel begins to rotate, thereby preventing the passenger carrier from being in a lower position than that required for boarding when passing through the valley of the mountains and valleys -Curve train can.

Dieser Nachteil wird durch die Konstruktion nach der DE-A-22 06 339 verhindert, bei welcher der obere Drehkranz längs einer gekrümmten Säule mit Hilfe einer Laufkatze geführt wird. Ein durch den Innenraum der Säule geführter Hubmotor verstellt den oberen Drehkranz. Ein gleichzeitiges Beginnen der Rotation des Karussells und der Höhenverstellung des oberen Drehkranzes ist bei diesem Stand der Technik dadurch möglich geworden, daß der Mittelpunkt der Säulenkrümmung ungefähr mit dem Radius der einzelnen Zugstange übereinstimmt und außerdem etwa horizontal von der Grundstellung des oberen Drehkranzes entfernt liegt. Damit wird erreicht, daß der einzelne Fahrgastträger während des Durchfahrens eines Wellentales nicht oder nicht wesentlich tiefer bis zu einer Stellung bewegt wird, in welcher sich der Fahrgastträger beim Stillstand des Karussells befindet.This disadvantage is prevented by the construction according to DE-A-22 06 339, in which the upper slewing ring is guided along a curved column using a trolley. A lifting motor guided through the interior of the column adjusts the upper slewing ring. Simultaneously starting the rotation of the carousel and the height adjustment of the upper turntable has become possible in this prior art in that the center point of the column curvature approximately corresponds to the radius of the individual pull rod and is also approximately horizontal from the basic position of the upper turntable. The result of this is that the individual passenger carrier is not moved, or is not moved substantially lower, to a position in which the passenger carrier is when the carousel is at a standstill while driving through a trough.

Eine solche Anordnung führt jedoch zu getriebe- und lagertechnischen Schwierigkeiten, weil nämlich der obere Laufkranz an einer Laufkatze gelagert sein muß und die erheblichen Zugkräfte der Zugstangen an der Laufkatze von den Führungselementen aufgenommen werden müssen, die längs der gekrümmten Säule bewegbar sein müssen. Auch die Herstellung einer solchen gekrümmten Säule bedingt einen hohen fertigungstechnischen Aufwand.However, such an arrangement leads to difficulties in terms of gearboxes and storage, because the upper running ring must be mounted on a trolley and the considerable tensile forces of the pull rods on the trolley must be absorbed by the guide elements, which must be movable along the curved column. The production of such a curved column also requires a high level of manufacturing complexity.

Der Erfindung liegt damit die Aufgabe zugrunde, ein Karussell zu entwickeln, das einerseits das gleichzeitige Besteigen und Bewegen der Fahrgastträger im Sinne einer Rotation und einer Berg- und Talfahrt ermöglicht und andererseits hinsichtlich der Kinematik und des getriebetechnischen Aufwandes einfacher gestaltet ist.The invention is therefore based on the object of developing a carousel which, on the one hand, enables the simultaneous ascent and movement of the passenger carriers in the sense of a rotation and an ascent and descent, and on the other hand is made simpler in terms of kinematics and the expenditure on transmission technology.

Ausgehend von der DE-A-22 06 339 besteht das Wesen der Erfindung darin, daß der obere Drehkranz von einem sich etwa horizontal und radial von der Grundachse sich erstreckenden Schwenkrahmen getragen und drehbar geführt ist, dessen Schwenklager an einem seitlichen Ausleger einer um die Grundachse drehbar angetriebenen Nabe in der Nähe der Zugstangen-Anlenkung an dem Fahrgast-Ausleger angeordnet ist, und daß sich an der Nabe ein auf den Schwenkrahmen einwirkender Hubmotor abstützt.Starting from DE-A-22 06 339, the essence of the invention is that the upper slewing ring is supported and rotatably supported by a pivot frame which extends approximately horizontally and radially from the basic axis, the pivot bearing of which is mounted on a lateral arm around the basic axis rotatably driven hub is arranged in the vicinity of the drawbar linkage on the passenger boom, and that a lifting motor acting on the swivel frame is supported on the hub.

Der Gegenstand der Erfindung kommt also ohne eine gekrümmte Säule als Führungselement aus und vereinfacht die komplizierten kinematischen Probleme dadurch, daß der obere Drehkranz in einem Schwenkrahmen gelagert ist, dessen Schwenklager die auf den Drehkranz einwirkenden pulsierenden Kräfte ohne weiteres aufzunehmen in der Lage ist. Dadurch werden erhebliche getriebetechnische Vereinfachungen herbeigeführt und komplizierter Bauaufwand vermieden.The object of the invention thus does not require a curved column as a guide element and simplifies the complicated kinematic problems in that the upper swivel head is mounted in a swivel frame, the swivel bearing of which is able to easily absorb the pulsating forces acting on the swivel head. This brings about considerable simplifications in terms of transmission technology and prevents complicated construction work.

Durch die nicht vorveröffentlichte EP-A-0 283 872 ist ein nach Artikel 54(3) EPÜ zu behandelnder Stand der Technik offenbart worden, der einige Merkmale der Erfindung enthält. Danach sind ebenfalls zwei um die gleiche vertikale Achse rotierende Drehkränze übereinander angeordnet, von denen der eine die Ausleger gelenkig trägt und der andere über radiale Zugstangen mit den Auslegern gelenkig verbunden ist. Bei der Erfindung befindet sich jedoch der die Ausleger tragende Drehkranz in einer bodennahen unteren Stellung, was bei der älteren Anmeldung umgekehrt ist. Das wichtige Erfindungsmerkmal, wonach das Schwenklager des den oberen Drehkranz tragenden Schwenkrahmens in der Nähe der Zugstangen-Anlenkung an den Fahrgast-Ausleger liegen soll, wird beim Gegenstand der EP-A- 0 283 872 nicht verwirklicht.EP-A-0 283 872, which has not been published beforehand, has disclosed a prior art to be dealt with under Article 54 (3) EPC which contains some features of the invention. Thereafter, two turntables rotating about the same vertical axis are also arranged one above the other, one of which supports the booms in an articulated manner and the other is articulated to the booms via radial tie rods. In the invention, however, the turntable carrying the boom is in a lower position near the ground, which is the reverse in the earlier application. The important feature of the invention, according to which the pivot bearing of the pivot frame carrying the upper slewing ring should lie in the vicinity of the drawbar linkage to the passenger boom, is not realized in the subject of EP-A-0 283 872.

Im Rahmen der abhängigen Ansprüche sind einige Ausführungsvarianten der Erfindung erfaßt.Within the scope of the dependent claims, some embodiment variants of the invention are covered.

Wenn man die Nabe entgegengesetzt zum oberen Drehkranz der Fahrgast-Ausleger antreibt, erreicht man, daß die Lage der Maxima und Minima der Berg- und Tal-Fahrt sich fortwährend ändert.If you drive the hub in the opposite direction to the upper turntable of the passenger boom, the position of the maxima and minima of the uphill and downhill ride changes continuously.

Mit den Merkmalen der Ansprüche 3 und 4 wird erreicht, daß die Eigenbewegungen der Fahrgast-Ausleger und des Schwenkrahmens gegenseitig ungehindert erfolgen können, und zwar unabhängig davon, welche Schräglage der Schwenkrahmen einnimmt.With the features of claims 3 and 4 it is achieved that the inherent movements of the passenger boom and the swivel frame can occur mutually unimpeded, regardless of the inclined position of the swivel frame.

Die Merkmale des Anspruches 5 haben statische Bedeutung. Während bei dem Stand der Technik die Zugstangen in der Grundstellung des Karussells eine etwa horizontale Lage einnehmen, sind bei der Erfindung die Zugstangen in der Grundstellung des Karussells von der Mitte nach außen leicht abfallend angeordnet, was erhebliche Vorteile in der Kräfteableitung mit sich bringt. Im besonderen wird durch diese Anordnung die Auflagekraft des unteren Drehkranzes am Fundament des Karussells reduziert. Man kann sogar erreichen, daß die auf den unteren Zahnkranz einwirkenden Kräfte eine nach oben gerichtete Resultierende aufweisen.The features of claim 5 have static meaning. While in the prior art the tie rods assume an approximately horizontal position in the basic position of the carousel, in the invention the pull rods are arranged in a slightly sloping manner from the center outwards in the basic position of the carousel, which has considerable advantages in terms of force dissipation. In particular, this arrangement reduces the contact force of the lower slewing ring on the foundation of the carousel. It can even be achieved that the forces acting on the lower ring gear have an upward resultant.

Mit den Merkmalen des Anspruches 7 wird erreicht, daß das erfindungsgemäße Karussell auf einfachste Weise von der Betriebsstellung in eine Transportstellung umgerüstet werden kann, ohne daß schwergewichtige Bauteile entfernt werden müssen.With the features of claim 7 it is achieved that the carousel according to the invention can be easily converted from the operating position into a transport position without having to remove heavy-weight components.

Einzelheiten der Erfindung sind in der Zeichnung schematisch und beispielsweise dargestellt. Es zeigen:

  • Fig. 1: eine Seitenansicht des Karussells in seiner Grundstellung,
  • Fig. 2: eine Seitenansicht des Karussells gemäß Fig. 1 in seiner Betriebsstellung und
  • Fig. 3 und 4: Seitenansicht und Draufsicht des in die Transportstellung verstellten Karussells.
Details of the invention are shown schematically and for example in the drawing. Show it:
  • 1: a side view of the carousel in its basic position,
  • 2: a side view of the carousel according to FIG. 1 in its operating position and
  • 3 and 4: side view and top view of the carousel adjusted in the transport position.

Beim Ausführungsbeispiel der Fig. 1 und 2 weist das Karussell ein ortsfestes Grundgestell (1) auf, an dem ein unterer Drehkranz (2) um die Grundachse (25) drehbar gelagert und motorisch angetrieben ist. Da der motorische Antrieb wie bei herkömmlichen Karussells angeordnet werden kann, ist er nicht im Detail dargestellt.In the embodiment of FIGS. 1 and 2, the carousel has a stationary base frame (1) on which a lower turntable (2) is rotatably mounted about the base axis (25) and is driven by a motor. Since the motorized drive can be arranged like conventional carousels, it is not shown in detail.

An dem unteren Drehkranz (2) befinden sich mehrere horizontale Achsen (4), an denen Fahrgast-Ausleger (3) so schwenkbar angeordnet sind, daß diese Fahrgast-Ausleger (3) in einer etwa vertikalen Ebene auf und nieder schwenkbar sind. Diese Fahrgast-Ausleger (3) tragen als Flugkörper dargestellte, jedoch beliebig gestaltbare Fahrgasträger (5), die an Tragstangen (6) hängen und an einem Drehkreuz (7) gelagert ist. Dieses Drehkreuz (7) ist seinerseits im Lager (8) am Fahrgast-Ausleger (3) um eine etwa vertikale Achse drehbar aufgehängt und von einem motorischen Antrieb (9) angetrieben.On the lower slewing ring (2) there are several horizontal axes (4), on which passenger booms (3) are pivoted so that these passenger booms (3) can be pivoted up and down in an approximately vertical plane. These passenger booms (3) carry passenger carriers (5), which are shown as missiles, but can be designed as desired, which hang on support rods (6) and are mounted on a turnstile (7). This turnstile (7) is in turn suspended in the bearing (8) on the passenger boom (3) so that it can rotate about an approximately vertical axis and is driven by a motor drive (9).

Nähere Einzelheiten einer solchen Anordnung und eines zugehörigen Antriebes sind in einer parallelen Erfindung offenbart.Further details of such an arrangement and an associated drive are disclosed in a parallel invention.

Jeder Fahrgast-Ausleger (3) ist über eine Zugstange (10) mit einem oberen Drehkranz (11) gelenkig verbunden. In der in Fig. 1 gezeigten Stellung ist die auslegerseitige Anlenkachse (12) geringfügig niedriger als die dem oberen Drehkranz (11) zugeordnete Anlenkachse (12′) angeordnet. Eine solche Maßnahme hat besondere Bedeutung in statischer Hinsicht hinsichtlich der Ableitung und Aufnahme von Kräften. So wird beispielsweise der untere Drehkranz (2) hinsichtlich seiner Auflagekraft am Grundgestell (1) wesentlich entlastet. Dieser Drehkranz (2) kann sogar eine nach oben gerichtete Resultierende der auf ihn einwirkenden Kräfte besitzen.Each passenger boom (3) is articulated via a tie rod (10) to an upper slewing ring (11). In the position shown in Fig. 1, the boom-side articulation axis (12) is arranged slightly lower than the articulation axis (12 ') assigned to the upper slewing ring (11). Such a measure is particularly important from a static point of view with regard to the derivation and absorption of forces. For example, the lower slewing ring (2) is significantly relieved in terms of its bearing force on the base frame (1). This slewing ring (2) can even have an upward resultant of the forces acting on it.

Der obere Drehkranz (11), an dem die Zugstangen (10) angelenkt sind, ist auf einem Schwenkrahmen (13) gelagert, der um das Schwenklager (15) an einem Ausleger (14) der Nabe (16) beweglich geführt ist. Diese Nabe (16) ist durch einen ebenfalls nicht dargestellten motorischen Antrieb um die Grundachse (25) verdrehbar, bevorzugt in Gegenlaufrichtung zum unteren Drehkranz (2). Damit wandert der Ort des Schwenklagers (15). Zwischen dem Schenkrahmen (13) und dem an der Nabe (16) befestigten Ausleger (14) befindet sich beim Ausführungsbeispiel eine blasebalgartige Manschette (17), die einen Antrieb (18, 19) umgreift, der zur Höhenverstellung des Schwenkrahmens (13) aus der Grundstellung gemäß Fig. 1 in die Betriebstellung gemäß Fig. 2 bestimmt ist. Dieser motorische Antrieb besteht beim Ausführungsbeispiel aus einer Abstützung (19), die mit der Nabe (16) verbunden ist und aus einem Hubmotor (18), der gelenkig mit der Abstützung (19) und dem Schwenkrahmen (13) verbunden ist.The upper slewing ring (11), on which the tie rods (10) are articulated, is mounted on a swivel frame (13) which is movably guided around the swivel bearing (15) on a bracket (14) of the hub (16). This hub (16) can be rotated about the basic axis (25) by a motor drive, also not shown, preferably in the opposite direction to the lower turntable (2). The location of the pivot bearing (15) thus moves. Between the gift frame (13) and the bracket (14) attached to the hub (16) there is a bellows-type sleeve (17) in the exemplary embodiment, which surrounds a drive (18, 19) which is used to adjust the height of the swivel frame (13) from the basic position shown in FIG 1 is determined in the operating position according to FIG. In the exemplary embodiment, this motor drive consists of a support (19) which is connected to the hub (16) and of a lifting motor (18) which is connected in an articulated manner to the support (19) and the swivel frame (13).

Es ist zwar denkbar, daß der Hubmotor (18) auch im Grundgestell (1) abgestützt sein kann. Dann sind jedoch kardanische oder Kugelgelenk-Führungen erforderlich, die das Anheben des Schwenkrahmens (13) und dessen Rotation aufzunehmen in der Lage sind.It is conceivable that the lifting motor (18) can also be supported in the base frame (1). Then, however, gimbal or ball joint guides are required, which are able to take up the swivel frame (13) and to rotate it.

Sowohl in der Grundstellung gemäß Fig. 1 als auch in der Betriebsstellung gemäß Fig. 2 dürfen die Fahrgast-Ausleger (3) und der Schwenkrahmen (13) bzw. Ausleger (14) sich während ihrer Drehbewegung nicht gegenseitig behindern. Zu diesem Zweck ist bei Ausführungsbeispiel der Fahrgast-Ausleger (3) als eine Art dreischenkeliger Hebel ausgebildet, dessen mittlerer Schenkel (20) die Anlenkachse (12) für die einzelne Zugstange (10) trägt. Dieser mittlere Schenkel (20) ist nasenartig gekrümmt ausgebildet. Er umgreift das Schwenklager (15) des Schwenkrahmens (13) bzw. des Auslegers (14).Both in the basic position according to FIG. 1 and in the operating position according to FIG. 2, the passenger boom (3) and the swivel frame (13) or boom (14) must not interfere with one another during their rotational movement. For this purpose, in the exemplary embodiment, the passenger boom (3) is designed as a type of three-legged lever, the middle leg (20) of which supports the articulation axis (12) for the individual pull rod (10). This middle leg (20) is curved like a nose. It engages around the swivel bearing (15) of the swivel frame (13) or the boom (14).

Eine solche Maßnahme ist deswegen zweckmäßig, um die Anlenkachse (12′) der Zugstange (10) in der Nähe des Schwenklagers (15) zu bringen, weil diese Maßnahme garantiert, daß die in Bewegung befindlichen Fahrgastträger (5) keine tiefere oder wesentlich tiefere Stellung als in der Ruhestellung gemäß Fig. 1 zum Zwecke des Besteigens einnehmen. Dadurch ist zugleich die Möglichkeit gegeben, die Rotation des Karussells gleichzeitig mit der Höhenverstellung des oberen Drehkranzes (11) und damit der Fahrgastträger (5) durchzuführen.Such a measure is therefore useful to bring the articulation axis (12 ') of the tie rod (10) in the vicinity of the pivot bearing (15), because this measure guarantees that the moving passenger carrier (5) is not a lower or significantly lower position as in the rest position shown in FIG. 1 for the purpose of climbing. This also gives the possibility of rotating the carousel at the same time as the Height adjustment of the upper slewing ring (11) and thus the passenger carrier (5).

Wie die Figuren 3 und 4 zeigen, brauchen die Fahrgast-Ausleger (3) sowie die Drehkränze (2, 11) und die Zugstangen (10) genauso wie der Schwenkrahmen (13) und der Ausleger (14) mit der Nabe (16) entfernt zu werden, um das erfindungsgemäße Karussell aus der Betriebsstellung in eine Transportstellung zu verändern.As FIGS. 3 and 4 show, the passenger boom (3) as well as the turntables (2, 11) and the tie rods (10) as well as the swivel frame (13) and the boom (14) with the hub (16) need to be removed to change the carousel according to the invention from the operating position to a transport position.

Sowohl die Fahrgast-Ausleger (3) als auch die Zugstangen (10) sind an ihren Drehkränzen (2, 11) mit Hilfe mehrerer Schrauben (21) befestigt, deren Anzahl und Größe von statischen Überlegungen abhängt. Jeweils eine dieser Schrauben (21) ist jedoch an einer solchen Stelle angeordnet, daß sie in ihrer Stellung verbleibt, während die anderen Schrauben (21) gelöst sind. Damit wird eine Schwenkachse (22) gebildet, welche das Verschwenken der Fahrgast-Ausleger (3) und der Zugstangen (10) in einer aus Fig. 4 erkennbare Stellung ermöglicht. In dieser Stellung sind die Fahrgast-Ausleger (3) zueinander etwa parallel liegend auf einem Transportwagen (24) dargestellt, wobei erkennbar ist, daß diese Fahrgast-Ausleger (3) die Länge des Transportwagens (24) kaum überschreiten und außerdem innerhalb der seitlichen Kontur dieses Transportwagens (24) sich befinden. Damit die Fahrgast-Ausleger (3) und die Zugstangen (10) in dieser Transportstellung gemäß Fig. 3 und 4 nicht Relativbewegungen zueinander ausführen können, sind geeignete Verbindungsmittel (23) vorgesehen.Both the passenger boom (3) and the tie rods (10) are attached to their turntables (2, 11) with the aid of several screws (21), the number and size of which depends on static considerations. However, one of these screws (21) is arranged in such a position that it remains in its position while the other screws (21) are loosened. A pivot axis (22) is thus formed, which enables the pivoting of the passenger boom (3) and the tie rods (10) in a position recognizable from FIG. 4. In this position the passenger booms (3) are shown lying approximately parallel to one another on a transport trolley (24), it being evident that these passenger booms (3) hardly exceed the length of the transport trolley (24) and also within the lateral contour this trolley (24) are. Suitable connecting means (23) are provided so that the passenger boom (3) and the tie rods (10) cannot move relative to one another in this transport position according to FIGS. 3 and 4.

Es ist demnach lediglich erforderlich, die Fahrgastträger (5) zu demontieren und Teile des Drehkreuzes (7) zu entfernen, um das erfindungsgemäße Karussell transportfähig auszurüsten.It is therefore only necessary to dismantle the passenger carrier (5) and remove parts of the turnstile (7) in order to equip the carousel according to the invention so that it can be transported.

Claims (7)

1. Carousel with a lower rotating ring (2) mounted for rotation about a main vertical axis and on which passenger booms (3) extending in an approximately radial direction and having passenger carriers (5) are mounted for pivotal movement about horizontal axes, and are articulated via radial tie rods to an upper rotating ring (11) which is motor movable from a lower position, approximately coincident to the main axis, into a raised, laterally offset and slanted upper position, characterised in that the upper rotating ring (11) is carried and rotatably guided by a pivotal frame (13) extending approximately horizontally and radially from the main axis (25), and whereof the pivotal bearing (15) is arranged on a lateral boom (14) of a hub (16) rotatably driven about the main axis (25) near the coupling (12) of the tie rods to the passenger boom (3), and in that a lifting motor (18) acting on the pivotal frame (13) is supported on the hub (16).
2. Carousel according to Claim 1, characterised in that the hub (16) is driven in opposition to the upper rotating ring (11) of the passenger booms (3).
3. Carousel according to Claim 1 or 2, characterised in that the single passenger boom (3) is constructed as a three-legged lever and the tie rod (10) is coupled to the middle leg thereof (20).
4. Carousel according to Claim 3, characterised in that the middle leg (20) is curved in the manner of a hook and surrounds the peripheral movement path of the pivotal frame (13).
5. Carousel according to Claim 1 or one of the subsequent claims, characterised in that the axle (12) of coupling of the tie rod (10) to the passenger boom (3), in the base position of the carousel, lies marginally lower than the axle (12′) of coupling of the tie rod (10) to the upper rotating ring (11).
6. Carousel according to Claim 1 or one of the subsequent claims, characterised in that the pivotal frame (13) is connected to the hub (16) by means of a bellows-type sleeve (17).
7. Carousel according to Claim 1 or one of the subsequent claims, characterised in that the passenger booms (3) and the tie rods (10) are screwed to the rotating rings (2, 11) by means of a plurality of screwed (21) arranged lateral to their radial vertical plane, such that one of the screws forms a pivotal axle (22) for tilting the passenger booms (3) and tie rods (10) into a mutually approximately parallel conveying position.
