Description

Die Erfindung betrifft eine Teleskoptribüne mit in mehreren Etagen angeordneten Sitzreihen die teleskqpartig ausfahrbar sind, wie z.B. aus Dokument US-A-4854092 bekannt.The invention relates to a telescopic tribune arranged in several floors Rows of seats which can be extended telescopically, such as from document US-A-4854092 known.

Bei bekannten Teleskoptribünen wird das Ausfahren der Sitzreihen über einen Reibradantrieb ermöglicht. Dabei werden die Fahrtbewegungen über gummibeschichtete Walzen durch entsprechenden Bodendruck übertragen. Die Walzen werden von einem Getriebemotor angetrieben. Meist sind mehrere solche Antriebselemente in einem Teleskoptribünenblock installiert. Die Anzahl ist von der Länge und Größe der Tribüne abhängig.In known Teleskoptribünen the extension of the rows of seats over a Friction wheel drive allows. The movements are over rubber-coated rollers transmitted by appropriate ground pressure. The Rollers are driven by a geared motor. Most are several such Drive elements installed in a telescopic grandstand block. The number is from the Length and size of the grandstand dependent.

Es ist ebenfalls bekannt, das Ausfahren der Sitzreihen mit Hilfe eines Raupenantriebs zu ermöglichen. Dabei werden die Fahrtbewegungen über gummibeschichtete Raupenketten, ähnlich wie bei einem Panzer, durch entsprechenden Bodendruck übertragen. Die Raupen werden von einem Getriebemotor angetrieben.It is also known, the extension of the rows of seats using a caterpillar drive to enable. The movements are rubber-coated Caterpillar tracks, similar to a tank, by corresponding ground pressure transfer. The caterpillars are driven by a geared motor.

Bei den bekannten Teleskoptribünen mit Reibrad- oder Raupenantrieb treten folgende Nachteile auf. Infolge von Schlupf kann es beim Ausfahren der Sitzreihen zu einem Verkanten einzelner Elemente der Teleskoptribüne kommen. Außerdem wird durch den Schlupf ein exaktes paralleles Ausfahren der einzelnen Sitzreihen erschwert. Demzufolge ist es fast unmöglich, ohne zusätzliche Positionierhilfen, exakte Endstellungen zu erreichen.

Dabei werden die Ausfahrbewegungen über Zugseile mit entsprechenden Umlenkungen und einer motorbetriebenen Seiltrommel ausgeführt. Infolge von unterschiedlichen Seildehnungen ist es fast unmöglich, ein exaktes Ausfahren der Sitzreihen zu gewährleisten. Demzufolge können auch keine exakten Endstellungen ohne die Verwendung von zusätzlichen Endabschaltungen erreicht werden. Darüber hinaus ist der Seilzugantrieb sehr wartungsintensiv. Ein beliebiges Ansteuern der Sitzreihen ist nur über externe Verriegelungen möglich.In addition, telescopic stands are known in which the extension of the individual Seat rows is achieved by means of a cable drive.

In addition, it is the cable drive very maintenance-intensive. An arbitrary driving the rows of seats is only possible via external interlocks.

Desweiteren können Hydraulik- oder Pneumatikantriebe verwendet werden, um das Ausfahren des einzelnen Sitzreihen zu realisieren. Bei Hydraulikantrieben können doppelt wirkende Schub- und Druckzylinder verwendet werden, um die Aus- und Einfahrbewegung der Sitzreihen zu realisieren. Bei Pneumatikantrieben können einfach wirkende Zylinder verwendet werden, die mit einem Seilrückzugsantrieb gekoppelt sind. Ein Hydraulik- oder Pneumatikantrieb ist jedoch relativ aufwendig und teuer in der Installation. Außerdem ergeben sich bei der Verwendung von mehreren Zylindern in einer Sitzreihe Probleme beim Parallellauf. Eine Endabschaltung kann nur mit Hilfe von mechanischen Endschaltern realisiert werden. Außerdem sind die Hydraulik- und Pneumatikantriebe sehr wartungsintensiv. Eine beliebige Ansteuerung einzelner Sitzreihen ist nur über externe Verriegelungen möglich.Furthermore, hydraulic or pneumatic drives can be used to To realize extension of the single rows of seats. For hydraulic drives can Double-acting push and push cylinders are used to remove the Entry movement of the rows of seats to realize. For pneumatic actuators can single-acting cylinders are used with a rope retracting drive are coupled. However, a hydraulic or pneumatic drive is relatively expensive and expensive in the installation. In addition, when using multiple Cylinders in a row of seats Problems with parallel operation. An end stop can can only be realized with the help of mechanical limit switches. In addition, the Hydraulic and pneumatic drives very maintenance-intensive. Any control Single rows of seats are only possible via external locks.

An der Innerseite der Sitzverkleidung 6 ist, wie am Besten in Figur 2 zu sehen ist, ein Verbindungselement 8 befestigt. In dem Verbindungselement 8 ist eine Mutter 9 drehbar. Die Mutter 9 ist mit einem Innengewinde ausgestattet. Durch die Mutter 9 hindurch erstreckt sich eine Schraube 10. Der Kopf 11 der Schraube 10 ist von der Außenseite der Sitzverkleidung 6 her zugänglich. Die Mutter ist entweder stelbsthemmend oder mit einer Sicherung ausgestattet. Dadurch wird erreicht, dass sich die Mutter im eingebauten Zustand zusammen mit der Schraube dreht und die Schraube axial fixiert.On the inside of the seat cover 6, as best seen in Figure 2, a Attached fastener 8. In the connecting element 8 is a nut. 9 rotatable. The nut 9 is equipped with an internal thread. By the mother 9 extends through a screw 10. The head 11 of the screw 10 is of the Outside of the seat cover 6 ago accessible. The mother is either self-locking or equipped with a safety device. This ensures that the nut rotates when installed with the screw and the Screw fixed axially.

An dem freien Ende der Schraube 10 ist ein Anschlußteil 12 mit einem Innengewinde befestigt. Ein Verdrehen der Schraube 10 bewirkt, dass sich der Abstand zwischen der Sitzverkleidung 6 und dem Anschlußteil 12 verändert. Dadurch können Toleranzen beim Einbau ausgeglichen werden. Darüber hinaus kann die Schraube 10 auch komplett aus dem Anschlußteil 12 herausgedreht werden.At the free end of the screw 10 is a connection part 12 with an internal thread attached. Twisting the screw 10 causes the distance between the seat cover 6 and the connection part 12 changed. Thereby can Tolerances are compensated during installation. In addition, the screw 10 be completely unscrewed from the connector 12.

Das Anschlußteil 10 ist mit Hilfe eines Zapfes 14 an einem Gelenkauge 15 einer Schubstange 16 montiert. Die Schubstange 16 ist in einem Führungsrohr 17 geführt, die zu einem Linearantrieb 18 gehört. Der Linearantrieb 18 ist durch ein weiteres Gelenkauge 19 an einer Mitnehmertraverse 21 befestigt. The connecting part 10 is by means of a pin 14 on a joint eye 15 of a Push rod 16 mounted. The push rod 16 is guided in a guide tube 17, which belongs to a linear drive 18. The linear drive 18 is through another Joint eye 19 attached to a Mitnehmertraverse 21.

In der in Figur 5 dargestellten Draufsicht ist zu sehen, dass die Mitnehmertraverse 21 die Form eines U hat, dessen Schenkel an den Enden 22 und 23 um 90° abgewinkelt sind. Die Enden 22 und 23 der Mitnehmertraverse 21 sind an Stützen 24 und 25 der jeweils nächsten Sitzreihe befestigt.In the plan view shown in Figure 5 can be seen that the Mitnehmertraverse 21st has the shape of a U, whose legs angled at the ends 22 and 23 by 90 ° are.

This means, the push rods 16 are arranged in the interior of the guide tubes 17. The extended position of the rows of seats 1 and 2 is by outlines 29 and 30th indicated. The retraction of the seat row 3 would due to the coupling on the Mitnehmertraversen 21 cause the rows of seats 1 and 2 together with the Seat row 3 are retracted by belonging to the seat row 3 linear drive.

Wie vorab schon erwähnt, dient die Verstellung der Schraube 10 der Aufnahme von Einbautoleranzen. In einem Störungsfall bei eingefahrener Teleskoptribüne wird durch das Herausdrehen der Schraube 10 in Richtung des Pfeils 13 das Anschlußteil 12 von dem Gewinde der Schraube 10 entfernt. Dadurch wird die Sitzreihe von dem zugehörigen Linearantrieb gelöst. Dann kann die Siztreihe manuell bewegt werden. In diesem Fall stützt ein Halteblech 32 den Linearantrieb 18 davor, dass er abkippt. Eine Draufsicht des Halteblechs 32 ist in Figur 4 dargestellt. Das Halteblech 32 ist an einem Querträger 31 befestigt.As already mentioned, the adjustment of the screw 10 is the recording of Installation tolerances. In a fault case with retracted telescopic tribune is by unscrewing the screw 10 in the direction of arrow 13, the connecting part 12 removed from the thread of the screw 10. This will make the row of seats of the associated linear drive solved. Then the Siztreihe can be moved manually. In In this case, a holding plate 32 supports the linear drive 18 in that it tilts. A top view of the retaining plate 32 is shown in FIG. The retaining plate 32 is on attached to a cross member 31.
