Description

Die Erfindung betrifft eine auf Bodenauflageteilen horizontal verschiebbare Teleskoptribüne bei der Sitzreihen an Trägerteilen im vorderen Bereich der Tribünenstufen derart angeordnet sind, daß sich bei in die Gebrauchslage ausgefahrener Tribüne die Sitzhöhe aus dem Abstand zwischen Sitzfläche und der jeweils nächstunteren Tribünenstufe ergibt, wobei die einzelnen Tribünenstufen rückseitig an vertikalen Stützen befestigt sind, und bei der die Tribünenstufen in der Stapellage parallel und bündig mit in einer vertikalen Ebene liegenden Vorderteilen der Sitzteile über einander liegen.The invention relates to a telescopic grandstand horizontally displaceable on floor support parts in the rows of seats on support parts in the front area of the grandstand steps such that when the grandstand is extended into the use position, the seat height results from the distance between the seat surface and the next lower grandstand step, the individual grandstand steps at the rear are attached to vertical supports, and in which the grandstand steps in the stack position are parallel and flush with the front parts of the seat parts lying in a vertical plane one above the other.

Teleskoptribünen zur platzsparenden wahlweisen Tribünenbestückung sind für Hallen und Stadien bekannt.Telescopic stands for space-saving optional seating for stands are known for halls and stadiums.

Bei einer solchen vorbekannten Ausführungsform einer Teleskoptribüne nach der DE-PS 22 59 816 sind Sitzbänke vorgesehen die mit vertikalen Trägern jeweils an der Vorderseite einer Tribünenstufe schwenkbar angelenkt sind. Diese Tribünenstufen werden in der Stapellage derart abgeklappt, daß die Sitzbänke eine vertikale Frontfläche bilden. Dadurch entspricht die kleinste erreichbare Stufensteigung etwa der Breite einer Sitzbank. Soll die Teleskoptribüne aus der Stapellage in die Gebrauchslage überführt werden, so müssen die Sitzbänke jeweils von Hand aufgeklappt werden.In such a known embodiment of a telescopic grandstand according to DE-PS 22 59 816, benches are provided which are pivotably articulated with vertical supports on the front of a grandstand step. These stands are folded down in the stack position so that the seats form a vertical front surface. As a result, the smallest possible step increase corresponds to the width of a bench. If the telescopic grandstand is to be transferred from the stacked position to the use position, the seats must be opened by hand.

Durch die US-PS 2 183 056 ist eine Teleskoptribüne bekannt, bei der mit Fahrwerkteilen Standstützen der einzelnen Tribünenstufen verbunden sind. Die von den Standstützen in der ausgezogenen Gebrauchslage nach rückwärts auskragenden Träger der Tribünenstufen sind an den Standstützen nicht starr befestigt, sondern die Standstützen sind in Führungshülsen verschiebbar. Dabei liegen in der Gebrauchslage der Tribüne die Abstützpunkte der Sitzreihen auf den entsprechenden Standstützen. Da sich die Sitzflächen von den Vorderteilen nach rückwärts erstrecken, muß die Sitzhöhe der Höhe der Einschuböffnung in einer Tribünenstufe entsprechen, wenn einerseits das Zusammenfahren in die Abstellage nicht behindert und andererseits eine im wesentlichen geschlossene Vorderfront erzielt werden soll. Es erscheint daher nicht möglich, bei dieser Ausführung relativ niedere Tribünenstufen mit Sitzelementen von angemessener Höhe zu kombinieren.A telescopic grandstand is known from US Pat. No. 2,183,056, in which stand supports of the individual grandstand steps are connected to chassis parts. The supports of the grandstand steps projecting backwards from the stand supports in the extended position of use are not rigidly attached to the stand supports, but the stand supports can be displaced in guide sleeves. The support points of the rows of seats are on the corresponding stand supports in the use position of the grandstand. Since the seats extend backwards from the front parts, the seat height must correspond to the height of the insertion opening in a grandstand step if, on the one hand, the moving into the storage position is not impeded and, on the other hand, an essentially closed front is to be achieved. It therefore does not seem possible to combine relatively low grandstand steps with seating elements of a reasonable height in this version.

Für verschiedene Anwendungsfälle wird jedoch eine geringe Stufensteigung, d.h. ein geringer Höhenunterschied zweier aufeinanderfolgender Tribünenstufen gewünscht. Dadurch wird unter anderem vermieden, daß zwischen zwei aufeinanderfolgenden Tribünenstufen eine Zwischenstufe eingefügt werden muß, wenn die Stufensteigung 200 mm überschreitet. Außerdem lassen sich bei Verwendung einer geringen Stufensteigung im Vergleich zu einer größeren Stufensteigung bei gleicher Höhe mehr Tribünenstufen und damit mehr Zuschauerplätze unterbringen.For different applications, however, a slight step increase, i.e. a small difference in height between two successive grandstand levels is desired. This prevents, among other things, that an intermediate step must be inserted between two successive grandstand steps if the step incline exceeds 200 mm. In addition, when using a small step incline compared to a larger step incline with the same height, more grandstand steps and thus more spectator seats can be accommodated.

Der Erfindung liegt die Aufgabenstellung zugrunde, eine Teleskoptribüne so auszubilden, daß eine geringe Stufensteigung bei einfacher Handhabung möglich wird. Das allgemeine Prinzip der Erfindung läßt sich auch bei Teleskoptribünen mit normalen Stufensteigungen anwenden und erreicht dort ebenfalls einen Gebrauchsvorteil.The invention is based on the problem of designing a telescopic grandstand in such a way that a small step gradient is possible with simple handling. The general principle of the invention can also be applied to telescopic stands with normal step gradients and also achieves a practical advantage there.

Die Aufgabenstellung der Erfindung wird dadurch gelöst, daß die Trägerteile aus im Bereich der vorderen Kanten der Tribünenstufen an Auflageteilen angeordneten, vertikalen Schenkeln und aus vorderseitig winkelförmig abgebogenen, in Längsrichtung bündige Sitzteile tragenden, horizontalen Schenkeln bestehen, wobei die Sitzteile an den Tribünenstufen derart starr befestigt sind, daß deren Vorderteile in der Stapellage eine vertikale Ebene bilden, wobei nächstuntere und/oder nächstobere vertikale Schenkel gegeneinander versetzt sind, so daß sie in der Stapellage in Längsrichtung der Sitzteile einen Überdeckungsbereich bilden. Bei dieser Ausführungsform ist es möglich, die Teleskoptribüne ausschließlich durch horizontales Verschieben der Bodenauflageteile aus der Gebrauchslage in die Stapellage zu überführen und umgekehrt, wodurch sich eine erleichterte Bedienung ergibt. Bei den Sitzteilen, deren Trägerteile in horizontaler Richtung eine Überdeckung aufweisen, sind die Trägerteile an den entsprechenden Tribünenstufen in Längsrichtung gegeneinander versetzt, wodurch die Sitzteile in der Stapellage übereinander zu liegen kommen. Durch das bündige Übereinanderliegen der Sitzteile in Längsrichtung und durch die Bildung einer vertikalen Ebene aus den Vorderteilen der Sitzteile wird eine nahezu geschlossene Front der Teleskoptribüne in der Stapel- bzw. Abstellage erreicht.The object of the invention is achieved in that the support parts consist of vertical legs arranged in the region of the front edges of the grandstand steps on support parts and of frontally angularly bent, horizontal legs supporting longitudinally flush seat parts, the seat parts being rigidly attached to the grandstand steps are that the front parts form a vertical plane in the stack position, the next lower and / or upper vertical legs being offset from one another, so that they form an overlap area in the stack position in the longitudinal direction of the seat parts. In this embodiment, it is possible to transfer the telescopic grandstand from the position of use into the stacking position and vice versa solely by horizontally displacing the floor support parts, which results in easier operation. In the case of the seat parts, the support parts of which have an overlap in the horizontal direction, the support parts are offset in the longitudinal direction at the corresponding grandstand steps, as a result of which the seat parts come to lie one above the other in the stacked position. Due to the flush overlapping of the seat parts in the longitudinal direction and the formation of a vertical plane from the front parts of the seat parts, an almost closed front of the telescopic stand is achieved in the stacking or storage position.

Eine zweckmäßige Weiterbildung kann vorsehen, daß ein Bereich der Tribünenstufe von Sitzteilen derart ausgespart ist, daß ein treppenartiger Aufgangsbereich entsteht und daß der treppenartige Aufgangsbereich in der Stapellage durch eine vorgehängte Abdeckplatte bündig zu der durch die Sitzteile bestimmten vertikalen Ebene abdeckbar ist. Dadurch entsteht in der Stapellage eine geschlossene Stirnfläche. Die Abdeckplatte läßt sich zweckmäßig in den entsprechenden Halteteilen der Tribünenstufen einhängen.An expedient further development can provide that an area of the grandstand step of seat parts is recessed in such a way that a stair-like entrance area is created and that the stair-like entrance area in the stack position can be covered by a curtain-covered cover plate flush with the vertical plane determined by the seat parts. This creates a closed end face in the stack position. The cover plate can be conveniently hung in the corresponding holding parts of the grandstand steps.

Die Bodenauflageteile können beispielsweise wie in der DE-PS 24 56 697 und in der DE-OS 37 09 753 dargestellten Ausführungsform bodenverfahrbar ausgebildet sein. Diese Ausführung ermöglicht ein einfaches Auseinander- und Zusammenfahren der Teleskoptribüne mit geringem Kraftaufwand.The floor support parts can, for example, be designed such that they can be moved on the floor as shown in DE-PS 24 56 697 and in DE-OS 37 09 753. This design enables the telescopic grandstand to be easily moved apart and moved together with little effort.

In einer weiteren vorteilhaften Ausbildung kann die Stufensteigung zwischen aufeinanderfolgenden Tribünenstufen unterhalb von 250 mm liegen, vorzugsweise kleiner als 200 mm sein. Dadurch wird die Notwendigkeit der Einfügung von Zwischenstufen zwischen zwei Tribünenstufen vermieden.In a further advantageous embodiment, the step gradient between successive grandstand steps can be less than 250 mm, preferably less than 200 mm. This avoids the need to insert intermediate steps between two grandstand steps.

Es kann zweckmäßig sein, an der Vorderseite der Tribünenstufen Auflageteile einzusetzen, welche in der Gebrauchslage auf entsprechenden Stützteilen der jeweils nächstunteren Tribünenstufe aufliegen.It may be expedient to use support parts on the front of the grandstand steps, which in the use position rest on corresponding support parts of the next lower grandstand step.

Ein zusätzlicher Vorteil läßt sich gegebenenfalls dadurch erreichen, daß die Sitzhöhe im Bereich zwischen 350 mm und 550 mm liegt.An additional advantage can be achieved if the seat height is in the range between 350 mm and 550 mm.

Es kann ferner vorteilhaft sein, daß zwischen den paarweise angeordneten vertikalen Stützen, an denen die Tribünenstufen einseitig auskragend befestigt sind, lastaufnehmende Diagonalstreben vorgesehen sind.It can also be advantageous that load-absorbing diagonal struts are provided between the vertical supports arranged in pairs, on which the grandstand steps are fixed on one side with a cantilever.

Bei der in den Figuren 1-4 dargestellten Ausführungsform der Teleskoptribüne mit sechs Tribünenstufen 1-6 sind paarweise bodenverfahrbare Bodenauflageteile 7,8,9,10,11,12 vorgesehen. An den Bodenauflageteilen 7-12 befinden sich vertikale Stützen 13,14,15,16,17,18, an denen auskragende Tragearme 19,20,21,22,23,24 angeordnet sind, welche Oberflächenbelegungen 25,26,27,28,29,30 als Trittflächen der Tribünenstufen 1-6 tragen. Im vorderen Bereich jeder Tribünenstufe sind an den Tragearmen 19-24 Auflageteile 31,32,33,34,35,36 vorgesehen, wobei die Auflageteile 32,33,34,35,36 in der Gebrauchslage auf entsprechenden Stützteilen 37,38,39,40,41 der nächstunteren Tribünenstufe aufliegen.In the embodiment of the telescopic grandstand with six grandstand steps 1-6 shown in FIGS. 1-4, floor-moving parts 7, 8, 9, 10, 11, 12 are provided in pairs. On the floor support parts 7-12 there are vertical supports 13, 14, 15, 16, 17, 18, on which projecting support arms 19, 20, 21, 22, 23, 24 are arranged, which surface assignments 25, 26, 27, 28 Wear 29.30 as steps of grandstand steps 1-6. In the front area of each stage of the grandstand 19-24 support parts 31, 32, 33, 34, 35, 36 are provided on the support arms, the support parts 32, 33, 34, 35, 36 in the position of use on corresponding support parts 37, 38, 39,. 40.41 of the next lower grandstand level.

Im Bereich der vorderen Kanten der Tribünenstufen 1-6 sind an den Auflageteilen 31,32,33,34,35,36 jeweils die vertikalen Schenkel 42,43,44,45,46,47 der Trägerteile der Sitzreihen angeordnet, wobei die horizontalen Schenkel 48,49,50,51,52,53 vorderseitig winkelförmig abgebogene Sitzteile 54,55,56,57,58,59 z.B. aus Kunststoff tragen. Die Vorderteile der Sitzteile 54,55,56,57,58,59 bilden wie in Fig. 2 erkennbar eine vertikale Ebene und ergeben damit in der Stapellage eine geschlossene Vorderfront.In the area of the front edges of the grandstand steps 1-6, the vertical legs 42, 43, 44, 45, 46, 47 of the support parts of the rows of seats are arranged on the support parts 31, 32, 33, 34, 35, 36, the horizontal legs 48,49,50,51,52,53 wear angular bent seat parts 54,55,56,57,58,59 at the front, e.g. made of plastic. As can be seen in FIG. 2, the front parts of the seat parts 54, 55, 56, 57, 58, 59 form a vertical plane and thus result in a closed front in the stacked position.

Figur 3 läßt den Überdeckungsbereich der vertikalen Schenkel 42,43,44,45,46,47 der Trägerteile für die Sitzelemente erkennen. Außerdem ist ein treppenartiger Aufgangsbereich D der Tribüne dargestellt.FIG. 3 shows the area of overlap of the vertical legs 42, 43, 44, 45, 46, 47 of the carrier parts for the seat elements. In addition, a step-like entrance area D of the grandstand is shown.
