Description
Die Erfindung betrifft eine verfahrbare Vorrichtung zum Heben oder Versenken von Personen oder Gegenständen, insbesondere für Theaterbühnen, umfassend einen mittels Seilzügen heb- und senkbaren Hubtisch.The invention relates to a movable device for lifting or lowering people or objects, in particular for theater stages, comprising a lifting table which can be raised and lowered by means of cable pulls.
Böden von Theaterbühnen weisen versenkbare und verschiebbare Bodenabschnitte auf, die dem Zweck dienen, Öffnungen in dem Bühnenboden freizugeben, um an dieser Stelle Personen, Gegenstände und dgl. verschwinden oder erscheinen zu lassen. Derartige Bodenabschnitte, auch Versenkungsschieber genannt, die im Ruhezustand bodengleich in die Bühne integriert sind, werden einzeln oder in Gruppen koordiniert auf schienenartigen Führungen mittels Rollen oder Kufen verschoben. Nach einem neueren Vorschlag wird der bewegbare Bühnenbodenabschnitt einseitig an der Bühnenkonstruktion gelagert und mit Hilfe eines Betätigungsorgans, das an der Unterseite des bewegbaren Abschnittes angreift, zum Öffnen und Schließen verschwenkt.Theater stage floors have retractable and displaceable floor sections which serve the purpose of opening openings in the stage floor in order to make people, objects and the like disappear or appear at this point. Such floor sections, also called countersink slides, which are integrated into the stage at ground level in the idle state, are moved individually or in groups coordinated on rail-like guides by means of rollers or runners. According to a more recent proposal, the movable stage floor section is supported on one side on the stage construction and is pivoted for opening and closing with the aid of an actuating member which acts on the underside of the movable section.
Für Auftritte von unten oder Abgänge von oben sind versenkbare Plattformen, sogenannte Hubtische, unter der vorgesehenen Bühnenbodenöffnung positioniert, auf denen Personen oder dgl. auf Bühnenniveau angehoben bzw. auf das Niveau des Bühnenkellers abgesenkt werden.For appearances from below or exits from above, retractable platforms, so-called lifting tables, are positioned under the intended stage floor opening, on which people or the like are raised to the stage level or lowered to the level of the stage basement.
Es sind Hubvorrichtungen für Hubtische bekannt, bei deren Konstruktion nach dem Prinzip des Gabelstaplers verfahren wird. Bei diesen Konstruktionen ist es erforderlich, daß zur Überbrückung des Abstandes der maximalen Hubhöhe bis zum Bühnenniveau eine zusätzliche Scherenkonstruktion aufgebaut wird. Das Aus- und Einfahren der Scheren kann von Hand oder mittels motorischem Antrieb erfolgen. Die Plattform des Versenktisches besitzt eine bestimmte Grundfläche, auf die der Fahrrahmen der Vorrichtung zugeschnitten ist.Lifting devices for lifting tables are known, the construction of which is based on the principle of the forklift. In these constructions it is necessary that an additional one to bridge the distance of the maximum lifting height to the stage level Scissor construction is built. The shears can be extended and retracted manually or by means of a motor drive. The platform of the lowering table has a certain area on which the moving frame of the device is tailored.
Für unterschiedlich große Bühnenbodenöffnungen müssen daher mehrere Versenkvorrichtungen mit Plattformen entsprechender Flächenabmessungen bereitgestellt werden.For different sizes of stage floor openings, several recessing devices with platforms of corresponding surface dimensions must therefore be provided.
Die aus diesem Konstruktionsprinzip resultierenden Maßnahmen haben zur Folge, daß derartige Versenkungen mit Tischgrößen von etwa 1 mal 1 Metern und Nutzlasten von etwa 2.000 Newton ungefähr eine Tonne schwer werden. Dieses Gewicht bereitet Schwierigkeiten hinsichtlich der Handhabung der Vorrichtung.The measures resulting from this design principle have the consequence that such countersinks with table sizes of approximately 1 by 1 meter and payloads of approximately 2,000 Newtons become approximately one ton. This weight creates difficulties in handling the device.
Aufgabe der Erfindung ist es, eine Versenkvorrichtung für Theaterbühnen zu schaffen, die vielseitig verwendbar ist, d.h. sowohl fahrbar und hinsichtlich der Hubhöhe des Hubtisches variabel, die aber vor allem mit unterschiedlich großen Hubtischen ausgerüstet werden kann. Die Vorrichtung soll ferner ähnlich einer stationären Versenkung in eine vorhandene Bühnen-Unterkonstruktion einschraubbar sein.The object of the invention is to provide a lowering device for theater stages which is versatile, i.e. Both mobile and variable with regard to the lifting height of the lifting table, which, however, can above all be equipped with lifting tables of different sizes. The device should also be able to be screwed into an existing stage substructure similar to a stationary countersink.
Nach der Erfindung wird diese Aufgabe in der Weise gelöst wie es die Patentansprüche angeben.According to the invention, this object is achieved in the manner specified by the claims.
Der Fahrrahmen der erfindungsgemäßen Vorrichtung ist zweiteilig und läßt das Einhängen von Hubtischen unterschiedlicher Größe zu. Üblich sind beispielsweise Tischgrößen von 1 mal 1 Meter, 2 mal 1 Meter, 3 mal 1 Meter, 4 mal 1 Meter oder ähnl.The driving frame of the device according to the invention is in two parts and allows lifting tables of different sizes to be attached. For example, table sizes of 1 by 1 meter, 2 by 1 meter, 3 by 1 meter, 4 by 1 meter or similar are common.
Der nutzbare, aus zu hebenden bzw. zu versenkenden Personen oder Gegenständen bestehende Teil der Last, die das erfindungsgemäße Transport- und Hebemittel aufnehmen kann, beträgt bei einer Tischgröße von 1 mal 2 Metern beispielsweise 10 Kilo-Newton statisch und 5 Kilo-Newton dynamisch.The usable part of the load consisting of people or objects to be lifted or lowered, which the transport and lifting means according to the invention can hold, is, for a table size of 1 x 2 meters, for example 10 kilo newtons static and 5 kilo newtons dynamic.
Ein besonderer Vorteil der erfindungsgemäßen Vorrichtung besteht darin, daß sie nach dem Baukastensystem konzipiert ist, d.h. sie ist in Gestalt von Einzelteilen geringen Gewichts leicht zu transportieren und einzurichten.A particular advantage of the device according to the invention is that it is designed according to the modular system, i.e. it is easy to transport and set up in the form of small parts.
Die erfindungsgemäße Vorrichtung wird in der Regel auf der Bühnenkeller eines Theaters installiert, wobei die teleskopierbaren Rollenträger der Windengestelle mittels Konsolen in eine vorhandene Unterbühnenkonstruktion eingeschraubt werden. Die Seilkräfte werden dann zum großen Teil direkt in die Unterbühnenkonstruktion eingeleitet.The device according to the invention is generally installed on the stage cellar of a theater, the telescopic roller carriers of the winch frames being screwed into an existing sub-stage structure by means of brackets. The rope forces are then largely introduced directly into the lower stage construction.
Die erfindungsgemäße Vorrichtung kann auch freistehend auf der Theaterbühne innerhalb einer Dekoration genutzt werden.The device according to the invention can also be used free-standing on the theater stage within a decoration.
Ein Ausführungsbeispiel der verfahrbaren Vorrichtung zum Heben oder Versenken wird an Hand der Zeichnungen nachstehend näher erläutert.An embodiment of the movable device for lifting or lowering is explained in more detail below with reference to the drawings.

In den Patentfiguren ist eine auf Rädern bewegbare Tischversenkungsvorrichtung auf dem Boden des Bühnenkellers (13) einer Theaterbühne positioniert. Die beiden Fahrrahmenteile (1, 2) mit den beiden Windengestellen (9) sind mit Hilfe von zwei Gitterträgern (3) zu einer Einheit verschraubt. Die Versenkvorrichtung besitzt in der Regel keinen Fahrantrieb, sondern wird von Hand bewegt.In the patent figures, a table lowering device which can be moved on wheels is positioned on the floor of the stage cellar (13) of a theater stage. The two chassis parts (1, 2) with the two winch frames (9) are screwed into one unit using two lattice girders (3). The lowering device usually has no travel drive, but is moved by hand.
Der Hubtisch (4) ist an Seilen (6) der Winden aufgehängt. Der Windenantrieb (7) befindet sich gemäß Fig.1 auf dem linken Fahrrahmenteil (1). Die Übertragung der Drehbewegung auf die Winde des rechten Fahrrahmenteils (2) erfolgt über eine beidseitig einsteckbare Gelenkwelle (8).The lifting table (4) is suspended on ropes (6) of the winch. The winch drive (7) is located on the left part of the chassis (1) as shown in FIG. The rotary motion is transmitted to the winch of the right-hand frame part (2) via a drive shaft (8) that can be inserted on both sides.
Wie aus Fig.2 ersichtlich, sind die oberen teleskopierbaren (10) Rollenträger (5) der Windengestelle (9) mit Hilfe von Konsolen (11) in die Unterbühnenkonstruktion eingeschraubt. Infolgedessen werden die Seilkräfte weitgehend direkt in die Unterbühnenkonstruktion eingeleitet.As can be seen from FIG. 2, the upper telescopic (10) roller carriers (5) of the winch frames (9) are screwed into the lower stage construction with the help of brackets (11). As a result, the rope forces are largely introduced directly into the lower stage construction.
Die Teleskopteile (10) der Windengestelle (9) werden zweckmäßigerweise mit Hilfe von Lasstangen (sog. Prospektzügen), die über der Theaterbühne angeordnet sind, hochgezogen und dann an den Konsolen (11) festgesetzt.The telescopic parts (10) of the winch frames (9) are expediently pulled up with the help of release rods (so-called brochure trains), which are arranged above the theater stage, and then attached to the brackets (11).
Die Teleskopierbarkeit der Windengestelle ermöglicht somit eine Anpassung an die jeweilige Höhe des Bühnenkellers und eine variable Hubhöhe des Hubtisches.The fact that the winch frames can be telescoped enables adaptation to the respective height of the stage cellar and a variable lifting height of the lifting table.
Der Hubtisch (4) wird mit Hilfe der Winden angehoben und abgesenkt. Beim Absenken taucht der Hubtisch (4) zwischen den beiden Gitterträgern (3) ein.The lifting table (4) is raised and lowered using the winches. When lowering, the lifting table (4) dips between the two lattice girders (3).
Als Zugang zum Hubtisch können (nicht dargestellte) mehrstufige Treppenelemente an den Längsseiten angestellt werden.Multi-level stair elements (not shown) can be placed on the long sides to access the lifting table.
Die Gitterträger (3) dienen auch als Schutzgeländer, mit dem der Raum unterhalb des angehobenen Hubtisches abgesperrt wird.The lattice girders (3) also serve as protective railings with which the space below the raised lifting table is blocked off.
Die zweiteilige Ausführung des Fahrrahmens der Versenkvorrichtung ermöglicht es, Hubtische (4) verschiedener Größe einzuhängen. Der sich dadurch verändernde Abstand der Fahrrahmenteile (1, 2) erfordert bei den Gitterträgern (3) entsprechend angepaßte Abstandsmaße und eine auf den jeweiligen Abstand ausgerichtete Gelenkwelle (8).The two-part design of the traveling frame of the lowering device enables lifting tables (4) of different sizes to be attached. The resulting changing distance between the chassis frame parts (1, 2) requires correspondingly adapted spacing dimensions for the lattice girders (3) and an articulated shaft (8) aligned with the respective spacing.
Der Transport der Versenkvorrichtung, z.B. von einem Standort auf dem Boden des Bühnenkellers auf die Theaterbühne erfolgt in Einzelteilen, die infolge ihres relativ niedrigen Gewichtes leicht zu befördern sind. Der Wiederaufbau der Versenkvorrichtung am neuen Standort ist infolge des Baukastensystems einfach, zumal die Einzelteile leicht handhabbar und einfach zu montieren sind.Transport of the sinking device, e.g. from a location on the floor of the stage cellar to the theater stage takes place in individual parts that are easy to transport due to their relatively low weight. The reconstruction of the sinking device at the new location is easy due to the modular system, especially since the individual parts are easy to handle and easy to assemble.
