If the actuator is then actuated in a suitable manner and thereby brought into its support position, the support plate comes to rest flat on the underside of the base plate.

Description

Die Erfindung betrifft einen Schwingboden nach dem Oberbegriff des Anspruchs 1.The invention relates to a sprung floor according to the preamble of claim 1.

Die JP H01 318 659 A offenbart einen elastischen Boden für Sportstätten mit einem Unterboden, einer Bodenplatte und einem Kolben-Zylinder-System, durch welches die Bodenplatte bei Anlage des Kolben-Zylinder-Systems abgestützt wird. Kommt das Kolben-Zylinder-System nicht an der Bodenplatte zur Anlage, erfolgt eine punktuelle Dämpfung der Bodenplatte mittels Spiralfedern.the JP H01 318 659 A discloses an elastic floor for sports facilities with a subfloor, a floor panel and a piston-cylinder system, by which the floor panel is supported when the piston-cylinder system is in contact. If the piston-cylinder system does not come into contact with the base plate, the base plate is selectively damped by means of spiral springs.

Ein gattungsgemäßer Schwingboden ist beispielsweise aus der EP 0 369 423 bekannt. Solche Schwingböden werden insbesondere, jedoch keineswegs ausschließlich, bei Tanzaufführungen von Ballettensembles benötigt, um die Gelenke der Tänzerinnen und Tänzer zu schonen. Die gattungsgemäßen Schwingböden sind dabei durch eine Flächenelastizität charakterisiert, so dass der Schwingboden bei Belastung in einem großen Bereich nachgeben kann. Insbesondere für die Benutzung als Tanzfläche für Ballettensembles kommen nur derartige flächenelastische Böden in Betracht, da punktelastische Böden, beispielsweise Elastomerböden, bei Belastung lediglich eine kleine Verformungsmulde bilden, die kaum größer als das belastende Objekt, beispielsweise der Fuß eines Tänzers, ist.A generic sprung floor is, for example, from EP 0 369 423 known. Such sprung floors are required in particular, but by no means exclusively, for dance performances by ballet ensembles in order to protect the dancers' joints. The generic sprung floors are characterized by a surface elasticity, so that the sprung floor can give way over a large area under load. In particular for use as a dance floor for ballet ensembles, only such area-elastic floors come into consideration, since point-elastic floors, for example elastomer floors only form a small deformation trough that is hardly larger than the loading object, for example a dancer's foot.

Um die gewünschte flächenelastische Eigenschaft zu erreichen, wird bei den bekannten Schwingböden eine Bodenplatte, beispielsweise aus Sperrholz, verwendet, die auf einem Schwingträger gelagert wird. Der Schwingträger selber kommt dabei auf einem festen Unterboden, beispielsweise einem Betonboden, zur Auflage. Der Schwingträger kann aus sich kreuzend angeordneten Gurtbrettern gebildet werden, die durch Distanzelemente voneinander beabstandet sind.In order to achieve the desired area-elastic property, a floor panel, for example made of plywood, is used in the known sprung floors, which is mounted on a oscillating support. The oscillating support itself comes to rest on a solid subfloor, for example a concrete floor. The oscillating support can be formed from crossing belt boards which are spaced apart from one another by spacer elements.

Die hohe Flächenelastizität der bekannten Schwingböden stellt bei der Verwendung auf Theaterbühnen ein erhebliches Problem dar. Denn die hohe Flächenelastizität der Schwingböden führt dazu, dass die Schwingböden nicht mit schweren Transportgeräten, beispielsweise Hubsteigern oder Gabelstaplern, befahren werden dürfen. Denn die von diesen schweren Geräten herrührenden Punktbelastungen, beispielsweise im Bereich der Räder eines Gabelstaplers, würden zur Zerstörung der Bodenplatte des Schwingbodens führen.The high area elasticity of the known sprung floors poses a significant problem when used on theater stages. Because the high area elasticity of the sprung floors means that the sprung floors must not be driven on with heavy transport equipment, such as cherry pickers or forklifts. Because the point loads originating from this heavy equipment, for example in the area of the wheels of a forklift, would lead to the destruction of the base plate of the sprung floor.

Aus diesem Grund werden die Schwingböden bei der Verwendung auf Theaterbühnen nur bei Bedarf auf der zu betanzenden Fläche der Bühne aufgelegt. Nach Abschluss der Ballettaufführung wird der Schwingboden dann wieder entfernt und muss an anderer Stelle eingelagert werden.For this reason, when used on theater stages, the sprung floors are only placed on the stage area to be danced on if necessary. After the end of the ballet performance, the sprung floor is then removed again and has to be stored elsewhere.

Diese Art der mobilen Verwendung des Schwingbodens zur Verwendung auf Theaterbühnen stellt einen erheblichen Kostenmehrbedarf dar, da neben der normalen Theaterbodenfläche noch ein zusätzlicher mobiler Schwingboden angeschafft werden muss. Außerdem stellt die Logistik zum Auf- und Abbau der mobilen Schwingböden einen erheblichen Organisations- und Arbeitsaufwand dar.This type of mobile use of the sprung floor for use on theater stages represents a considerable additional cost requirement, since an additional mobile sprung floor has to be purchased in addition to the normal theater floor area. In addition, the logistics for assembling and dismantling the mobile sprung floors represent a considerable amount of work and organization.

Ausgehend von diesem Stand der Technik ist es deshalb Aufgabe der vorliegenden Erfindung, einen neuen Schwingboden vorzuschlagen, der auch mit schwerem Arbeitsgerät befahren werden kann und dadurch die oben beschriebenen Nachteile von mobilen Schwingböden vermeidet.Based on this prior art, it is therefore an object of the present invention to propose a new sprung floor that can also be driven on with heavy equipment, thereby avoiding the disadvantages of mobile sprung floors described above.

Diese Aufgabe wird durch einen Schwingboden nach der Lehre des Anspruchs 1 gelöst.This problem is solved by a sprung floor according to the teaching of claim 1.

Vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject matter of the dependent claims.

Der erfindungsgemäße Schwingboden wird durch eine Stützplatte charakterisiert, die unter der Bodenplatte des Schwingbodens angeordnet ist. Der zumindest einen Stützplatte ist dabei zumindest ein Stellorgan zugeordnet, das zwischen einer Ruhestellung und einer Stützstellung verstellbar ist. Befindet sich das Stellorgan in seiner Ruhestellung, so besteht kein Kontakt zwischen der Stützplatte und der Bodenplatte, so dass der Schwingboden seine für die Tanzaufführung notwendigen flächenelastischen Eigenschaften aufweist. Wird dann das Stellorgan geeignet betätigt und dadurch in seine Stützstellung verbracht, so kommt die Stützplatte flächig an der Unterseite der Bodenplatte zur Anlage. Durch diesen Kontakt der Bodenplatte mit der darunter befindlichen Stützplatte wird die Bodenplatte von unten abgestützt und verliert ihre flächenelastischen Eigenschaften. Zugleich wird es aber möglich, dass die Bodenplatte mit der darunter zur Anlage gebrachten Stützplatte aufgrund der Stützeigenschaften der Stützplatte in gewünschter Weise mit schwerem Gerät, beispielsweise einem Hubsteiger oder einem Gabelstapler, befahren werden kann.The sprung floor according to the invention is characterized by a support plate which is arranged under the base plate of the sprung floor. The at least one support plate is associated with at least one actuator that can be adjusted between a rest position and a support position. If the actuator is in its rest position, there is no contact between the support plate and the floor plate, so that the sprung floor has the area-elastic properties necessary for the dance performance. If the actuator is then actuated in a suitable manner and thereby brought into its support position, the support plate comes to rest flat on the underside of the base plate. As a result of this contact of the floor panel with the support panel located underneath, the floor panel is supported from below and loses its area-elastic properties. At the same time, however, it is possible for heavy equipment, for example a cherry picker or a forklift truck, to be driven over the base plate with the support plate placed underneath due to the support properties of the support plate.

Im praktischen Betrieb ist es somit möglich, dass die für die Einrichtung der Bühne notwendigen Kulissen zunächst mit schwerem Gerät auf der Bühne positioniert werden, wobei eine Beschädigung der Bodenplatte aufgrund des Stützeffekts der Stützplatte ausgeschlossen ist. Vor der eigentlichen Tanzaufführung werden dann die am Schwingboden vorhandenen Stellorgane in die Ruhestellung verbracht, und dadurch wird der gewünschte Abstand zwischen Stützplatte und Bodenplatte hergestellt. Aufgrund dieses Abstands erhält dann die Bodenplatte wieder ihre gewünschte flächenelastische Eigenschaft, die für den Schutz der Gelenke der Tänzerinnen und Tänzer erforderlich ist.In practical operation, it is therefore possible for the backdrops required for setting up the stage to be positioned on the stage using heavy equipment, with damage to the base plate being impossible due to the supporting effect of the support plate. Before the actual dance performance, the adjusting elements on the sprung floor are brought into the rest position, and the desired distance between the support plate and the floor plate is thereby produced. Because of this distance, the floor panel regains its desired area-elastic properties, which is necessary to protect the dancers' joints.

Bei der Verwendung des Schwingbodens auf einer großen Theaterbühne ist es vielfach erforderlich, dass auch sehr schwere Kulissenelemente auf der Bühne aufgestellt werden. Aufgrund ihres hohen Gewichts ist die Aufstellung solcher Kulissenelemente auf einem normalen Schwingboden nicht möglich, da das Gewicht vom Schwingboden nicht getragen werden kann und es stattdessen zu Instabilitäten und Kulissenumstürzen kommt. In welchem Bereich einer Bühne die Kulissen dabei zur Aufstellung kommen, kann dabei stark variieren. Um dieses Problem mittels des erfindungsgemäßen Schwingbodens lösen zu können, ist es besonders vorteilhaft, wenn der Schwingboden zumindest zweigeteilte Nutzungsbereiche aufweist, wobei die Stellorgane in den verschiedenen Nutzungsbereichen unabhängig voneinander zwischen Ruhestellung und Stützstellung verstellbar sind. Auf diese Weise ist es möglich, den Schwingboden in unterschiedlichen Bereichen der Bühne wahlweise mit der Stützplatte abzustützen und damit gegenüber dem Gewicht auch von großen Kulissenelementen zu stabilisieren und zugleich in anderen Bereichen die flächenelastischen Eigenschaften des Schwingbodens zu realisieren, um einen betanzbaren Bereich zu bilden. Bei Änderung der Anordnung der Kulissenelemente auf der Bühne können dann jeweils entsprechend andere Bereiche des Schwingbodens durch Aktivierung der Stellorgane in den entsprechenden Bereichen wahlweise stabilisiert werden.When using the sprung floor on a large theater stage, it is often necessary to set up very heavy scenery elements on the stage. Due to their high weight, it is not possible to set up such backdrop elements on a normal sprung floor, since the weight of the sprung floor cannot be borne and instabilities and scenery overturning occur instead. In which area of a stage the backdrops are set up can vary greatly. In order to be able to solve this problem using the sprung floor according to the invention, it is particularly advantageous if the sprung floor has at least two-part usage areas, with the adjusting elements in the different usage areas being adjustable independently of one another between the rest position and the supporting position. In this way it is possible to optionally support the sprung floor in different areas of the stage with the support plate and thus to stabilize it against the weight of large scenery elements and at the same time to realize the area-elastic properties of the sprung floor in other areas in order to form an area where people can dance. When changing the arrangement of the link elements on the stage, other areas of the sprung floor can then be selectively stabilized by activating the actuators in the corresponding areas.

Welche Art von Stellorgan zum Anheben bzw. Absenken der Stützplatte verwendet wird, ist grundsätzlich beliebig. Im Hinblick auf die Betriebssicherheit, insbesondere Feuersicherheit, ist es besonders vorteilhaft, wenn das für die Bildung des Schwingbodens verwendete Stellorgan in der Art eines oder mehrerer pneumatisch betätigbarer Stempel ausgebildet ist. Solche pneumatische Stempel weisen eine hohe Betriebssicherheit auf, da insbesondere keinerlei Feuergefahr entstehen kann.It is fundamentally arbitrary which type of actuator is used to raise or lower the support plate. With regard to operational safety, in particular fire safety, it is particularly advantageous if the actuating element used to form the sprung floor is designed in the manner of one or more pneumatically actuated stamps. Such pneumatic stamps have a high level of operational reliability, since in particular there is no risk of fire.

Die konstruktive Ausbildung der pneumatischen Stempel zum Anheben bzw. Absenken der Stützplatte ist grundsätzlich beliebig. Bevorzugt sollten die pneumatisch betätigbaren Stempel eine Längserstreckung aufweisen und parallel zur unteren Gurtbrettlage des Schwingträgers verlaufend auf dem Unterboden gelagert werden. Auf diese Weise können dann große Stützplattenelemente eingesetzt werden, die auf den Stempeln gelagert sind und zwischen den Gurtbrettern der oberen Gurtbrettlage nach oben gefahren werden können, um an der Unterseite der Bodenplatte zur Anlage zu gelangen.The design of the pneumatic stamp for raising or lowering the support plate is fundamentally arbitrary. The pneumatically actuable stamps should preferably have a longitudinal extension and be mounted on the underbody running parallel to the lower belt board layer of the oscillating support. In this way, large support plate elements can then be used, which are mounted on the rams and can be moved upwards between the belt boards of the upper belt board layer in order to come to rest on the underside of the base plate.

Eine besonders einfache konstruktive Möglichkeit zur Ausbildung der pneumatisch betätigbaren Stempel ergibt sich, wenn diese jeweils in einem im Querschnitt offenen Lagerprofil höhenverstellbar gelagert sind.A particularly simple constructive possibility for the formation of the pneumatically actuated stamp results when these are each mounted in a height-adjustable manner in a bearing profile which is open in cross section.

Um die Verstellung der Stempel in einfacher Weise mit pneumatischen Mitteln realisieren zu können, können geeignete Druckschläuche, beispielsweise Feuerwehrschläuche, verwendet werden. Diese Druckschläuche werden dann zwischen der Unterseite des Stempels und der Innenseite des Lagerprofils angeordnet. Beim Aufblasen der Druckschläuche wird dann der Stempel, der in dem Lagerprofil gehalten ist, angehoben und drückt auf diese Weise die Stützplatte mit ihrer Oberseite an die Unterseite der Bodenplatte.Suitable pressure hoses, for example fire hoses, can be used in order to be able to adjust the plungers in a simple manner using pneumatic means. These pressure hoses are then placed between the bottom of the ram and the inside of the bearing profile. When the pressure hoses are inflated, the plunger, which is held in the bearing profile, is then raised and in this way presses the upper side of the support plate against the underside of the base plate.

Bei Aktivierung der Stellorgane und der Anhebung der Bodenplatte soll vermieden werden, dass die Bodenplatte von der Stützplatte aus ihrer Normalposition nach oben gedrückt wird. Denn ein Anheben der Bodenplatte ist nicht gewünscht, da es ansonsten zu Unebenheiten in der Tanzfläche kommt. Um dies zu erreichen, sollte das Stellorgan zum Anheben der Stützplatte einen oberen Endanschlag aufweisen. Dieser obere Endanschlag kann in einfacher Weise durch die Schenkelenden des offenen Lagerprofils, in dem der Stempel des Stellorgans gelagert ist, realisiert werden.When the actuators are activated and the floor panel is raised, it should be avoided that the floor panel is pushed up from its normal position by the support panel. Because you don't want to lift the floor plate, otherwise there will be bumps in the dance floor. In order to achieve this, the actuator for raising the support plate should have an upper end stop. This upper end stop can be realized in a simple manner by the leg ends of the open bearing profile in which the plunger of the actuator is mounted.

Aus welchem Material die Stempel des Stellorgans hergestellt sind, ist grundsätzlich beliebig. Im Hinblick auf die Verwendung des Stellorgans im Bereich einer Bühne ist es besonders vorteilhaft, wenn diese Stempel aus Holz hergestellt werden.The material from which the stamps of the actuator are made is fundamentally arbitrary. With regard to the use of the actuator in the area of a stage, it is particularly advantageous if these stamps are made of wood.

Im Hinblick auf die Betriebssicherheit einer Theaterbühne ist es von herausragender Bedeutung, dass das Bühnenpersonal ohne Weiteres erkennen kann, ob der Schwingboden mit schwerem Gerät befahren werden darf bzw. ob der Schwingboden zur Aufstellung von schweren Kulissenelementen geeignet ist. Um diese Betriebssicherheit zu gewährleisten, sollte deshalb bevorzugt eine Steuereinrichtung vorgesehen werden, mit der das Stellorgan angesteuert wird. An dieser Steuereinrichtung ist dann eine Signalisierungseinrichtung, beispielsweise eine Warnleuchte oder ein Warnsignal oder Ähnliches, vorzusehen, mit welcher der Betriebszustand des Stützbodens mit der Anordnung in der Stützstellung oder Ruhestellung optisch und/oder akustisch signalisiert werden kann. Erst wenn das Betriebspersonal durch die Signalisierungseinrichtung signalisiert bekommt, dass die Bodenplatte durch Aktivierung der Stellorgane und der dadurch verursachten Anlage der Stützplatte an der Unterseite der Bodenplatte stabilisiert ist, dürfen schwere Arbeitsgeräte, beispielsweise Hubsteiger oder Gabelstapler, auf der Bühnenfläche verwendet werden. Nach Abschluss der Stellarbeiten auf der Bühnenfläche kann dann der betanzbare Bereich der Bühnenfläche in einen Betriebszustand mit flächenelastischen Eigenschaften gebracht werden, wobei dieser Betriebszustand wiederum geeignet an der Signalisierungseinrichtung signalisiert wird. Weist die Bühnenfläche mehrere getrennt voneinander ansteuerbare Flächenbereiche auf, so sollte die Signalisierungseinrichtung für jeden der Flächenbereiche ein separates Signalisierungsorgan, beispielsweise eine Warnlampe, aufweisen.With regard to the operational safety of a theater stage, it is of paramount importance that the stage staff can easily see whether the sprung floor can be driven on with heavy equipment or whether the sprung floor is suitable for the installation of heavy scenery elements. In order to ensure this operational reliability, a control device should preferably be provided with which the actuator is controlled. A signaling device, for example a warning lamp or a warning signal or the like, is then to be provided on this control device, with which the operating state of the support base with the arrangement in the support position or rest position can be signaled optically and/or acoustically. Heavy work equipment, such as cherry pickers or forklifts, may only be used on the stage surface when the operating personnel have been informed by the signaling device that the floor panel has been stabilized by activating the actuators and the resulting contact of the support panel with the underside of the floor panel. After completion of the adjustment work on the stage surface, the area of the stage surface that can be danced on can then be brought into an operating state with area-elastic properties, with this operating state in turn being suitably signaled on the signaling device. If the stage surface has several surface areas that can be controlled separately from one another, the signaling device should have a separate signaling element, for example a warning lamp, for each of the surface areas.

Um ein Befahren des Schwingbodens 06 mit schweren Arbeitsgeräten zu ermöglichen, wird unter der Bodenplatte 07 und jeweils zwischen den Gurtbrettern 09 eine Stützplatte 13 vorgesehen. In Fig. 2 ist die eine Stützplatte 13 nicht dargestellt, um die Erkennbarkeit des Aufbaus des Schwingbodens 06 zu erhöhen. Die Stützplatten 13 ihrerseits sind auf Stellorganen 14 gelagert, mit denen die Stützplatten 13 angehoben und abgesenkt werden können. Die Funktion der Stellorgane 14 bei der Verstellung der Stützplatte 13 soll nachfolgend anhand der Zeichnungen Fig. 3 und Fig. 4 näher erläutert werden.A support plate 13 is provided under the base plate 07 and between the belt boards 09 in order to enable heavy work equipment to be driven over the sprung floor 06 . In 2 one support plate 13 is not shown in order to make the structure of the sprung floor 06 easier to see. The support plates 13 in turn are mounted on actuators 14 with which the support plates 13 can be raised and lowered. The function of the actuators 14 when adjusting the support plate 13 is to be explained below with reference to the drawings 3 and 4 be explained in more detail.

Fig. 3 zeigt den Schwingboden 03 in einem Teilquerschnitt, wobei das in Fig. 3 dargestellte Stellorgan 14 sich in seiner Ruhestellung befindet. In der Ruhestellung des Stellorgans 14 besteht zwischen der Bodenplatte 07 und der Stützplatte 13 ein ausreichend großer Abstand 15, der ein Schwingen der Bodenplatte 07 ermöglicht und dadurch die erwünschten flächenelastischen Eigenschaften des Schwingbodens 06 realisiert. 3 shows the sprung floor 03 in a partial cross section, with the 3 illustrated actuator 14 is in its rest position. When the actuator 14 is in the rest position, there is a sufficiently large distance 15 between the base plate 07 and the support plate 13, which enables the base plate 07 to oscillate and thereby implements the desired area-elastic properties of the oscillating base 06.

Das Stellorgan 14 umfasst einen aus Holz gefertigten Stempel 16, der in einem Lagerprofil 17 höhenverstellbar ist. Zwischen der Unterseite des Stempels 16 und der Innenseite des Lagerprofils 17 befindet sich ein Druckschlauch 18, der mit Druckluft beaufschlagt werden kann.The actuator 14 includes a stamp 16 made of wood, the height of which is adjustable in a bearing profile 17 . There is a pressure hose 18 between the underside of the stamp 16 and the inside of the bearing profile 17, to which compressed air can be applied.

Fig. 4 zeigt den Schwingboden 06 mit dem in die Stützstellung ausgefahrenen Stellorgan 14 im Querschnitt. Durch Druckbeaufschlagung des Druckschlauchs 18 wird der Stempel 16 nach oben ausgefahren und die Stützplatte 13 von unten an der Bodenplatte 07 zur Anlage gebracht. Durch diesen Kontakt der Stützplatte 13 mit der Bodenplatte 07 verliert die Bodenplatte 07 ihre flächenelastischen Eigenschaften und kann anschließend problemlos mit schweren Arbeitsgeräten befahren werden. 4 shows the sprung floor 06 with the actuator 14 extended into the support position in cross section. By applying pressure to the pressure hose 18, the plunger 16 is extended upwards and the support plate 13 is brought to rest against the base plate 07 from below. As a result of this contact of the support plate 13 with the base plate 07, the base plate 07 loses its area-elastic properties and can then be driven on with heavy work equipment without any problems.

Die Schenkelenden 19 des offenen Lagerprofils 17 bilden dabei einen oberen Endanschlag, an dem die Stellbewegung des Stempels 16 nach oben definiert begrenzt wird. Ein übermäßiges Anheben der Stützplatte 13 wird dadurch ausgeschlossen.The leg ends 19 of the open bearing profile 17 form an upper end stop at which the actuating movement of the ram 16 is limited upwards in a defined manner. This prevents the support plate 13 from being lifted excessively.

Fig. 5 zeigt eine zweite Ausführungsform 20 eines erfindungsgemäßen Schwingbodens. Bei diesem Schwingboden 20 wird das Stellorgan 21 aus einem offenen Lagerprofil 22, einem Druckschlauch 23 und einem im Lagerprofil 22 höhenverstellbar gelagerten Stempel 24 gebildet. Der Stempel 24 selbst besteht dabei aus einem Längsprofil 25 aus Blech und einem daran befestigten Brettabschnitt 26. Durch Druckbeaufschlagung des Druckschlauchs 23 kann der Stempel 24 angehoben und dadurch die Stützplatte 27 von unten an der Bodenplatte 28 zur Anlage gebracht werden. Als Endanschläge für die Stellbewegung des Stempels 24 dienen Schraubbolzen 29, die das Längsprofil 25 des Stempels 24 in Ausnehmungen 30 durchgreifen. figure 5 shows a second embodiment 20 of a sprung floor according to the invention. In this sprung floor 20, the actuator 21 is formed from an open bearing profile 22, a pressure hose 23 and a height-adjustably mounted stamp 24 in the bearing profile 22. The ram 24 itself consists of a longitudinal profile 25 made of sheet metal and a board section 26 attached to it. Screw bolts 29 which pass through the longitudinal profile 25 of the stamp 24 in recesses 30 serve as end stops for the actuating movement of the stamp 24 .
