Fig. 1 zeigt eine aus Stahl in einen Geh- und/oder Fahrsteg umwandelbare Treppe 1, die aus einer ersten Treppe 2 und einer zweiten Treppe 3, wobei beide Treppe 2, 3 mit mehreren in Begehrichtung in regelmässigen Abständen zwischen zwei seitlich voneinander beabstandeten parallelen Längsträgern 4, 5 und 6, 7 angeordneten, als Treppe 1 jeweils eine horizontale Trittfläche 8 bildenden Trittelementen 9 ausgebildet sind, die gemeinsam aus einer Treppenstellung in einen ebenen Geh- und/oder Fahrsteg und zurück verstellbar sind. Die Längsträger 4 bis 7 weisen ein zur Seite hin C-förmiges Querschnittsprofil auf und sind durch mehrere in Begehrichtung voneinander distanzierte Abstandhalter 10 verbunden, sodass sie eine stabile resp. für hohe Lasten tragfähige Trageinrichtung 11 oder-gestell bilden. Die Trittelemente 9 weisen Gitterroste 12 zur Bildung der Trittflächen 8 auf und sind an den seitlichen Enden mit einem gegenüber der Trittfläche 8 hochstehenden Verbindungselement 13 ausgebildet. Die Trittelemente 9 sind um eine zu den Längsträgern 4 bis 7 rechtwinklige Achse 14 an den Längsträgern 4 bis 7 schwenkbar gelagert, wozu jeweils ein beidseits der Trittelemente 9 befestigter Wellenzapfen 15 vorgesehen ist, der jeweils eine Bohrung in den Längsträgern 4 bis 7 durchsetzt. Die mit den Trittelementen 9 seitlich verbundenen Verbindungselemente 13 weisen an dem vom Trittelement 9 entfernten Ende jeweils einen weiteren Zapfen 16 auf, so dass sich aus dem Abstand zwischen Wellenzapfen 15 und Zapfen 16 ein Hebel bildet, dessen Zapfen 16 mit einer Betätigungsstange 17 verbunden ist, wobei sowohl der ersten Treppe 2 wie auch der zweiten Treppe 3 jeweils eine Betätigungsstange 17 zur gemeinsamen Bewegung der Trittelemente 9 zugeordnet ist. Die auszugsweise dargestellte Treppe 1 weist auf beiden Seiten der Treppen 2, 3 eine die Trittelemente 9 verbindende Betätigungsstange 17 auf, sodass eine höhere Stabilität beim Begehen der Trittelemente 9 erreicht werden kann, wobei jedoch eine einseitige Anordnung von Betätigungsstangen 17 zur Verstellung der Trittelemente 9 bei genügender Steifigkeit der Bauelemente ausreichen würde. Die Verstellvorrichtungen für die Treppe 2 und Treppe 3 sind einerseits an einem Längsträger 4 bis 7 befestigt und andererseits mit einer Betätigungsstange 17 verbunden.
Sind -wie vorgeschlagen- die Treppen 2 und 3 miteinander begehbar verbunden, ist es zweckmässig, die Betätigungsstangen 17 der Treppen 2 und 3 zu kuppeln resp. mit dem Trittelement 9 eines Uebergangselementes zu kuppeln; hierzu ist nachfolgend wie folgt zu berichten.
Die Betätigungsstange 17 bildet mit den Verbindungselementen 13 der Trittelemente 9 eine Vielzahl von Hebelgetrieben auf wenigstens einer Seite der Treppen 2 und 3, sodass sich die Trittelemente 9 gemeinsam in eine einheitliche Lage verstellen lassen. Die Trittelemente 9 lassen sich um 90° verschwenken, so dass die Einrichtung als Treppe oder ebener Steg verwendet werden kann, wobei sie als Treppe einen Anstellwinkel zwischen 0° und 90° aufweisen kann. Die Verstellvorrichtungen der Treppen 2, 3 weisen einen Spindelantrieb zur Verstellung der Trittelemente 9 auf. Der Spindelantrieb ist mit einer Betätigungsstange 17 verbunden, wozu ein Gelenk vorgesehen ist. Der Antrieb einer Gewindespindel erfolgt durch eine Handkurbel. Durch die Verstellung der Trittelemente 9 ändern die Betätigungsstangen 17 die Lage in Richtung der Längsträger 4 bis 7 und den Abstand zu diesen, wogegen die Parallelität der Betätigungsstangen 17 erhalten bleibt.
Fig. 3 zeigt die Einrichtung als Geh- und/oder Fahrsteg, bei dem die durch die Verstellvorrichtung geänderte Lage der Trittelemente 9 eine ebene Geh- und/oder Fahrfläche bildet.
Ein auf beiden Seiten der Einrichtung resp. der Treppe 1 angeordnetes Geländer 18 ist auf die maximale Schutzhöhe angehoben und die Geländerpfosten 19 stehen etwa senkrecht zu den Tritt- resp. Tragflächen der Trittelemente 9 resp. senkrecht zur Geh- und/oder Fahrebene. Damit das Geländer 18 auch in einer Treppenstellung der Einrichtung genutzt werden kann, sind die Geländerpfosten 19 in ansteigender Gehrichtung betrachtet an dem hinteren Ende der Trittelemente 9 befestigt resp. an dem seitlichen hinteren Ende der Trittelemente 9 befestigt. Dies hat den weiteren Vorteil, dass das Geländer 18 zum Transport und zur Lagerung der Einrichtung auf ein geringe Höhe verstellt werden kann. Das Geländer 18 weist auch einen Handlauf 20 und eine von diesem beabstandete Knieleiste 21 auf, die an den Geländerpfosten 19 angelenkt sind. Die Geländerpfosten 19 stehen in jeder Treppenlage als auch bei ebener Lauffläche senkrecht zu den Trittflächen 8. Die Verteilung der Geländerpfosten 19 entlang der Längsträger 4 bis 7 kann regelmässig oder unregelmässig sein. Das Geländer 18 ist am oberen Ende einer Treppe 2, 3 durch einen mit dem letzten Trittelement 9 starr verbundenen Geländerendabschnitt 22 ausgestattet, an dem der Handlauf 20 und die Knieleiste 21 angelenkt sind. Dadurch, dass die Geländerpfosten 19 an dem unteren Ende einen abgewinkelten Abschnitte aufweisen, legen sie sich in zusammengeklapptem Transport- oder Lagerzustand der Einrichtung selbsttätig parallel zu den Längsträgern 4 bis 7 über die rechtwinklig zu den Längsträgern 4 bis 7 stehenden Trittelemente 9. Damit beanspruchen die Treppen 2, 3 weder beim Lagern noch beim Transport ungenutzten Raum. Die Koppelung zweier Treppen 2, 3 in zu einer Einrichtung mit grösserer Reichweite ist wenigstens ein Ende der Treppe 2 resp. des Geh- und/oder Fahrsteges zur begehbaren Verbindung mit einer weiteren Treppe 3, 2 resp. einem weiteren Geh- und/oder Fahrsteg mit einem wenigstens ein verstellbares Trittelement 9 aufweisenden, lösbar befestigten Uebergangselement 25 verbindbar ausgebildet. Hierzu ist das Trittelement 9 des Uebergangselementes 25 durch wenigstens ein Verbindungselement 13 mit der Betätigungsstange 17 verbunden, sodass dieses Trittelement 9 mit den anderen Trittelementen 9 der Treppe 2 oder einer Treppe 2, 3 verstellt werden kann. Alternativ ist es möglich, das Trittelement 9 des Uebergangselementes 25 mit einer Betätigungsstange 17 einer Treppe 2, 3 durch eine zusätzliche Verbindungsstange 26 zu verknüpfen resp. zu verbinden, wodurch die andere Treppe 3, 2 durch ihre eigene Verstellvorrichtung in einen Geh- und/oder Fahrsteg verstellt werden kann. Es ist jedoch möglich beide Treppen 2, 3 durch eine, vorzugsweise durch die Verstellvorrichtung der unteren Treppe 2 zu verstellen, indem eine Verbindungsstange verwendet wird, die die Betätigungsstange 17 beider Treppen 2, 3 verbindet und die mit dem Verbindungselement 13 resp. dem Hebel 24 des Trittelementes 9 des Uebergangselementes 25 verbunden ist. Sofern- wie oben beschrieben- die Verstellung der Trittelemente 9 über eine Gewindespindel erfolgt, ist die Verstellvorrichtung für die Treppe 3 von der Verstellvorrichtung zu lösen, da rückwirkend die Selbsthemmung an der Gewindespindel der Verstellvorrichtung für die Treppe 3 eintritt.
Das in den Figuren 1 bis 3 veranschaulichte Uebergangselement 25 ist mit den Längsträgern 4 bis 7 der Treppen 2, 3 form- und /oder kraftschlüssig verbunden. Hierzu besteht das in der Fig. 3 näher dargestellte Uebergangselement 25 aus einem Rahmen 27, an dem das verstellbare Trittelement 9 schwenkbar befestigt ist. Der Rahmen 27 weist zwei parallele Tragbalken 28, 29 aus stählernen Hohlprofilen auf, die an den Enden durch Querträger 30, 31 verbunden sind. Etwa auf die Längsmitte der Tragbalken 28, 29 verteilt sind jeweils zwei als Einsteckfassung 32, 33, 34, 35 bezeichnete Steckverbindungen auf den Tragbalken 28, 29 befestigt, die der einsteckweisen Aufnahme der Endabschnitte der Längsträger 4 bis 7 für eine begehbare Verbindung zwischen den Treppen 2, 3 resp. Geh- und/oder Fahrstegen dienen. Diese Einsteckfassungen 32 bis 35 weisen etwa einen inneren Querschnitt des äusseren Querschnitts der einzusteckenden Längsträger 4 bis 7 auf. Zwischen den Einsteckfassungen 32, 34 und 33, 35 verbindet ein weiterer Querträger 36 die Tragbalken 28, 29. Zur Bestimmung der Einstecklänge der Längsträger 4 bis 7 sind die Einsteckfassungen 32, 34; 33, 35 mit einem Anschlag 37 ausgebildet. Schräg von einer Deckplatte 38 der Einsteckfassungen 32, 34; 33, 35 an die Tragbalken 28, 29 verlaufende und eine seitliche Führung letzterer bildende Verbindungsstreben 39 sorgen für eine stabile Schweisskonstruktion. An der Deckplatte 38 sind Anhängebügel 40 befestigt um das Uebergangselement 25 mit einem Kran oder dgl. transportieren zu können.
