Description

Die Erfindung betrifft einen Fassadenaufzug für Wände mit zurückspringenden Teilen mit einer an Seilen aufgehängten Tragkonstruktion für eine daran um eine vertikale Achse drehbar gelagerte Gondel, deren Länge grösser ist als ihre Breite.The invention relates to a facade elevator for walls with recessed parts with a suspension structure suspended on cables for a gondola rotatably mounted thereon about a vertical axis, the length of which is greater than its width.

Fassadenaufzüge werden verwendet beim Putzen von Fenstern an Gebäuden, zur Ausführung von Reparaturen und zur Kontrolle von Fassaden. Die Seile, an denen die Gondel hängt, werden im allgemeinen über schwenkbare Ausleger zu einem auf dem Gebäudedach verfahrbaren Wagen geführt, der parallel zur Fassade verfahrbar ist. Die Steuerung des Hub- und Fahrwerkes erfolgt von der Gondel aus. Endschalter begrenzen den Hub des Fassadenaufzuges nach oben und unten. Nach Beendigung der Arbeiten an der Fassade kann die Gondel durch die schwenkbaren Ausleger auf dem Gebäudedach abgesetzt werden.Facade lifts are used for cleaning windows on buildings, for carrying out repairs and for checking facades. The ropes on which the gondola hangs are generally guided via swiveling brackets to a carriage which can be moved on the building roof and which can be moved parallel to the facade. The lift and undercarriage are controlled from the nacelle. Limit switches limit the lift of the facade lift up and down. After the work on the facade has been completed, the gondola can be lowered onto the roof of the building using the swivel arm.

Bei einem bekannten Fassadenaufzug der eingangs beschriebenen Gattung (FR-A 2 244 894) ist die Gondel an das Ende eines zu einer Pantographenführung gehörenden Tragarms angeschlossen. Die Pantographenführung ist ihrerseits an ein Drehlager der Tragkonstruktion angeschlossen. Dadurch können von der Gondel aus auch zurückspringende Fassadenteile, insbesondere Fenster, erreicht werden. Allerdings ist der bekannte Fassadenaufzug konstruktiv aufwendig, und die Steuerung der Gondel bereitet Schwierigkeiten.In a known facade elevator of the type described at the beginning (FR-A 2 244 894), the gondola is connected to the end of a support arm belonging to a pantograph guide. The pantograph guide is in turn connected to a pivot bearing of the supporting structure. In this way, recessed facade parts, in particular windows, can also be reached from the gondola. However, the well-known facade elevator is structurally complex and the control of the gondola is difficult.

Aufgabe der Erfindung ist es, einen Fassadenaufzug der eingangs beschriebenen Gattung konstruktiv und steuerungstechnisch zu verbessern.The object of the invention is to improve the design and control technology of a facade elevator of the type described in the introduction.

Diese Aufgabe wird dadurch gelöst, dass die Gondel mittels eines mittig am Boden und/oder am Dach angeordneten Drehlagers unmittelbar an der Tragkonstruktion gelagert ist.This object is achieved in that the nacelle is mounted directly on the supporting structure by means of a pivot bearing arranged centrally on the floor and / or on the roof.

Mit diesem Fassadenaufzug lassen sich zurückspringende Fassadenteile dadurch erreichen, dass die Gondel so gedreht wird, dass ihre Längsachse sich im wesentlichen orthogonal zur Fassade erstreckt, wobei dann die kürzere Seite der Gondel sich vor dem zurückspringenden Fassadenteil befindet. Die Neigung der Gondel durch einseitige Gewichtsbelastung beim Arbeiten an der Fassade bleibt gering, weil die Gondel um eine mittige Drehachse geschwenkt wird. Verbleibende Neigungswinkel können z. B. dadurch ausgeglichen werden, dass in der Gondel Ausgleichsgewichte mitgeführt und entsprechend angeordnet werden. Als Ausgleichsgewicht kann z. B. ein Wasserbehälter dienen, der beim Fensterputzen ohnehin erforderlich ist.With this facade elevator, recessed facade parts can be achieved by rotating the nacelle so that its longitudinal axis extends essentially orthogonally to the facade, the shorter side of the nacelle then being in front of the recessed facade part. The inclination of the gondola due to one-sided weight loading when working on the facade remains low because the gondola is pivoted about a central axis of rotation. Remaining angles of inclination can e.g. B. be compensated for by carrying counterweights in the nacelle and arranging them accordingly. As a balance weight z. B. serve a water container that is required anyway when cleaning the window.

Die Tragkonstruktion kann ein Rahmen aus vertikalen Stielen und horizontalen Traversen sein, wobei die Seile an die obere Traverse angeschlossen sind, während die Gondel an der oberen und/oder unteren Traverse gelagert ist. Insbesondere kann der Rahmen wenigstens zwei jeweils neben den kurzen Seiten der Gondel angeordnete Stiele aufweisen. Zweckmässiger ist jedoch eine Ausführungsform, bei der der Rahmen neben jeder kurzen Seite der Gondel zwei Stiele aufweist, die im Bereich der Gondelecken angeordnet sind. Damit ergibt sich eine stabile und tragfähige Konstruktion, die sich auch beim Verdrehen der Gondel relativ zur Tragkonstruktion betriebssicher verhält.The supporting structure can be a frame made of vertical supports and horizontal cross members, the cables being connected to the upper cross member, while the nacelle is mounted on the upper and / or lower cross member. In particular, the frame can have at least two stems arranged next to the short sides of the gondola. An embodiment is more expedient, however, in which the frame has two stems next to each short side of the gondola, which are arranged in the region of the gondola corners. This results in a stable and load-bearing construction, which behaves reliably even when the nacelle is rotated relative to the support structure.

Wenn die Gondel nur auf der unteren Traverse gelagert ist, empfiehlt es sich, die Seitenwände der Gondel nur bis in Hüfthöhe bzw. Brusthöhe reichen zu lassen. So hat der Fensterputzer oder dergleichen volle Bewegungsfreiheit im Bereich seines Oberkörpers und kann sich dennoch sicher an bzw. in der Gondel abstützen.If the gondola is only supported on the lower crossbeam, it is recommended that the side walls of the gondola only reach up to the waist or chest height. So the window cleaner or the like has full freedom of movement in the area of his upper body and can still be supported safely on or in the gondola.

Eine andere Ausführungsform der Erfindung ist dadurch gekennzeichnet, dass die Tragkonstruktion eine an den Seilen aufgehängte Traverse ist, an der die Gondel mit einem rahmenartigen Aufbau drehbar aufgehängt ist. Dabei kann der rahmenartige Aufbau der Gondel an den Ekken der Gondel angeordnete vertikale Stiele und eine an deren freien Enden befestigte Dachkonstruktion aufweisen, die an und unter der Traverse gelagert ist. Auch bei dieser Ausführungsform besitzt die Gondel mit Stielen und Dachkonstruktion eine hinreichende Steifigkeit, die ein sicheres Verdrehen der Gondel relativ zur Traverse ermöglicht.Another embodiment of the invention is characterized in that the supporting structure is a crossbar suspended from the cables, on which the gondola is rotatably suspended with a frame-like structure. The frame-like structure of the gondola can have vertical stems arranged on the corners of the gondola and a roof construction attached to the free ends thereof, which is mounted on and under the crossmember. In this embodiment too, the gondola with stems and roof construction has sufficient rigidity, which enables the gondola to be rotated relative to the crossbar.

Wenn die Traverse ebenfalls in einem im wesentlichen rechteckigen Grundriss gelagert ist und im Bereich ihrer Ecken an die Seile, d.h. an insgesamt vier Seilen angeschlossen ist, können die Seile ungleichmässig belastet sein, wenn die um 90° verdrehte Gondel einseitig belastet ist. Um eine gleichmässigere Seilbelastung zu erreichen, kann das Drehlager für die Gondel um eine horizontale Achse schwenkbar an der Traverse gelagert sein. Gegebenenfalls kann die horizontale Schwenkbarkeit des Drehlagers durch Anschläge begrenzt sein.If the traverse is also stored in a substantially rectangular plan and in the area of its corners on the ropes, i.e. connected to a total of four ropes, the ropes can be loaded unevenly if the nacelle rotated by 90 ° is loaded on one side. In order to achieve a more even rope load, the pivot bearing for the nacelle can be pivotally mounted on the crossbar about a horizontal axis. If necessary, the horizontal pivotability of the pivot bearing can be limited by stops.

Bei allen Ausführungsformen sollte wenigstens die das Drehlager aufnehmende Traverse eine der Gondelbreite entsprechende Breite und eine Länge aufweisen, die grösser ist als die Gondellänge, wobei das oder die Drehlager für die Gondel einen im wesentlichen der Traversenbreite entsprechenden Durchmesser aufweist. Insbesondere kann das Drehlager für die Gondel ein Drehkranz sein. Dadurch ist es möglich, die bei gegenüber der Traverse verdrehter Gondel und einseitiger Belastung der Gondel auftretenden Momente ohne Schwierigkeiten in das Lager und von dort in die Traverse zu übertragen.In all embodiments, at least the crossmember receiving the pivot bearing should have a width corresponding to the width of the gondola and a length which is greater than the length of the gondola, the pivot or pivot bearings for the gondola having a diameter substantially corresponding to the crossmember width. In particular, the pivot bearing for the nacelle can be a slewing ring. This makes it possible to transmit the moments occurring when the nacelle is rotated relative to the crossbar and the gondola is loaded on one side without difficulty into the bearing and from there into the crossbar.

Zur Begrenzung des Drehwinkels der Gondel können an der Gondel und der Tragkonstruktion Anschläge angeordnet sein. Im übrigen kann eine Vorrichtung zum Arretieren der Gondel relativ zur Tragkonstruktion vorgesehen sein.In order to limit the angle of rotation of the gondola, stops can be arranged on the gondola and the supporting structure. In addition, a device for locking the nacelle relative to the supporting structure can be provided.

Im folgenden werden in der Zeichnung dargestellte Ausführungsbeispiele der Erfindung erläutert; es zeigen:

  • Fig. 1 teilweise einen Schnitt durch die Fassade eines Gebäudes mit einem davor befindlichen Fassadenaufzug,
  • Fig. 2 einen Schnitt in Richtung 11-11 durch den Gegenstand nach Fig. 1,
  • Fig. 3 eine andere Ausführungsform des Gegenstandes nach Fig. 1,
  • Fig. 4 eine Ansicht in Richtung des Pfeils IV auf den Gegenstand nach Fig. 3.
Exemplary embodiments of the invention illustrated in the drawing are explained below; show it:
  • 1 is a partial section through the facade of a building with a facade elevator in front of it,
  • 2 shows a section in the direction 11-11 through the object according to FIG. 1,
  • 3 shows another embodiment of the object according to FIG. 1,
  • 4 is a view in the direction of arrow IV on the object of FIG. 3rd

In Fig. 1 ist die Fassade 1 eines Gebäudes dargestellt, das ein oder mehrere gegenüber der Fassade 1 zurückspringende Fassadenteile 2 mit Fenstern 3 aufweist.1 shows the facade 1 of a building which has one or more facade parts 2 with windows 3 that spring back against the facade 1.

Vor der Fassade 1 bzw. vor dem Fassadenteil 2 befindet sich ein Fassadenaufzug mit einer Gondel 4, die an Seilen 5 aufgehängt ist und die in einer zur Fassade 1 parallelen Ebene vertikal und horizontal beweglich ist. Die dargestellte Gondel 4 besitzt die übliche oben offene Kastenform mit bis etwa in Hüfthöhe reichenden Seitenwänden 6 und einem auf dem oberen Rand der äusseren Seitenwand 6 befestigten Geländer 7, das bis etwa in Brusthöhe reicht.In front of the facade 1 or in front of the facade part 2 there is a facade elevator with a gondola 4 which is suspended on ropes 5 and which can be moved vertically and horizontally in a plane parallel to the facade 1. The gondola 4 shown has the customary open box shape with side walls 6 reaching approximately at waist height and a railing 7 fastened to the upper edge of the outer side wall 6, which extends to approximately chest height.

Die Gondel 4 weist ferner einen Boden auf, der auf einem als Drehkranz ausgebildeten Lager 9 befestigt ist. Der andere Teil des Drehkranzes ist an einer Traverse 10 befestigt, die etwa die gleiche Breite wie die Gondel 4 besitzt und deren Länge etwas grösser als die Länge der Gondel 4 ist. Der Drehkranz weist einen Durchmesser auf, der nur wenig geringer ist als die Breite der Traverse 10.The nacelle 4 also has a base which is fastened on a bearing 9 designed as a rotating ring. The other part of the slewing ring is fastened to a crossmember 10 which has approximately the same width as the nacelle 4 and whose length is somewhat greater than the length of the nacelle 4. The slewing ring has a diameter that is only slightly less than the width of the cross member 10.

An den vier Ecken der Traverse 10 sind vertikale Stiele 11-14 angeordnet, die an ihren oberen Enden wiederum an einer Traverse 15 befestigt sind. Die obere Traverse 15 weist Anschlusselemente 16 für die an den Ecken der Traverse 15 befestigten Seile 5 auf.At the four corners of the crossmember 10 vertical stems 11-14 are arranged, which in turn are attached to a crossmember 15 at their upper ends. The upper cross member 15 has connection elements 16 for the cables 5 fastened to the corners of the cross member 15.

Für Arbeiten an der Fassade 1 befindet sich die Gondel 4 in der mit durchgezogenen Linien dargestellten Position relativ zu der aus den Traversen 10, 15 und den Stielen 11-14 gebildeten Tragkonstruktion, d.h. die längeren Seitenwände der Gondel 4 sind im wesentlichen parallel zur Fassade 1. Wenn ein gegenüber der Fassade 1 zurückspringendes Fassadenteil 2 oder ein darin angeordnetes Fenster 3 bearbeitet, z. B. geputzt, werden soll, wird die Gondel 4 um eine vertikale Achse 17 des Lagers 9 um etwa 90° verdreht, bis an der unteren Traverse 10 bzw. dem Boden 8 der Gondel 4 angeordnete Anschläge 18 bzw. 19 aufeinandertreffen. Mit einer nichtdargestellten Einrichtung kann die Gondel 4 relativ zur Tragkonstruktion in bestimmten Winkelstellungen arretiert werden. Die Gondel 4 nimmt nunmehr zur Fassade 1 die in den Fig. 1 und 2 mit gestrichelten Linien dargestellte Position ein, d.h. die längeren Seitenwände der Gondel erstrecken sich im wesentlichen orthogonal zur Fassade 1. Wie aus den Figuren ohne weiteres ersichtlich, reicht nunmehr die schmalere Seitenwand 20 der Gondel 4 erheblich dichter an das zurückspringende Fassadenteil 2 heran, so dass das darin angeordnete Fenster 3 ohne weiteres geputzt werden kann. Die durch die einseitige Gewichtsbelastung sich ergebende Neigung der Gondel 4 in dieser Arbeitsposition kann ohne weiteres durch Gewichte, z. B. durch einen auf der anderen Seite angeordneten Wasserbehälter, ausgeglichen werden.For work on the facade 1, the gondola 4 is in the position shown with solid lines relative to the support structure formed from the crossbeams 10, 15 and the stems 11-14, i.e. the longer side walls of the gondola 4 are essentially parallel to the facade 1. If a facade part 2 that springs back relative to the facade 1 or a window 3 arranged therein is processed, eg. B. to be cleaned, the nacelle 4 is rotated about a vertical axis 17 of the bearing 9 by about 90 ° until the lower crossmember 10 and the bottom 8 of the nacelle 4 arranged stops 18 and 19 meet. With a device not shown, the gondola 4 can be locked relative to the supporting structure in certain angular positions. The gondola 4 now takes up the position of the facade 1 in the position shown in FIGS. 1 and 2 with dashed lines, i.e. the longer side walls of the gondola extend essentially orthogonally to the facade 1. As can easily be seen from the figures, the narrower side wall 20 of the gondola 4 now extends considerably closer to the recessed facade part 2, so that the window 3 arranged therein is easily cleaned can be. The inclination of the gondola 4 resulting from the one-sided weight loading in this working position can be easily determined by weights, e.g. B. can be compensated by a water tank arranged on the other side.

Bei dem Ausführungsbeispiel nach den Fig. 3 und 4 bezeichnen gleiche Bezugszeichen gleiche Teile.In the embodiment according to FIGS. 3 and 4, the same reference numerals designate the same parts.

Bei dem in den Fig. 3 und 4 dargestellten Ausführungsbeispiel besitzt die Gondel 4 an ihren Ecken jeweils vertikale Stiele 21-24, die an ihren oberen Enden an eine Dachkonstruktion 25 angeschlossen sind. Die Dachkonstruktion 25 bildet mit den Stielen 21-24 und der Gondel 4 eine rahmenartige Konstruktion, die über das als Drehkranz ausgebildete Lager 9 an die an den Seilen 5 aufgehängte Traverse 15 angeschlossen ist. Selbstverständlich ist bei dieser Ausführungsform der Drehkranz so gestaltet, dass er auch die aus der Gewichtsbelastung resultierenden Zugkräfte aufnehmen kann. Man erkennt, dass die Gondel 4 ebenso wie bei dem in den Fig. 1 und 2 dargestellten Ausführungsbeispiel um die Achse 17 des Lagers 9 relativ zur Traverse 9 verdreht werden kann, bis sie die mit gestrichelten Linien dargestellte Position einnimmt.In the embodiment shown in FIGS. 3 and 4, the gondola 4 has vertical stems 21-24 at its corners, which are connected at their upper ends to a roof structure 25. The roof structure 25 forms with the stems 21-24 and the nacelle 4 a frame-like construction which is connected to the crossbar 15 suspended on the cables 5 via the bearing 9 designed as a rotating ring. Of course, in this embodiment, the slewing ring is designed so that it can also absorb the tensile forces resulting from the weight load. It can be seen that the nacelle 4, just as in the exemplary embodiment shown in FIGS. 1 and 2, can be rotated about the axis 17 of the bearing 9 relative to the crossmember 9 until it assumes the position shown in broken lines.

Da bei aussermittiger Gewichtsbelastung der Gondel 4 die Seile 5, die an die Ecken der Traverse 15 angeschlossen sind, nicht gleichmässig belastet sind, ist der der Traverse 15 zugehörige Teil des Lagers 9 in einem Gelenk 26 mit horizontaler Achse 27 an der Traverse 15 gelagert. Dazu weist die Traverse 15 eine Ausnehmung 28 auf, in der das der Traverse 15 zugehörige Lagerteil beweglich angeordnet ist, und dieses Lagerteil ist an einem Gelenkzapfen 29 aufgehängt, der beidseits in Konsolen 30, 31 gehalten ist. Gegebenenfalls können nichtdargestellte Anschläge vorgesehen sein, die die Schwenkbewegung um die horizontale Achse 27 begrenzen.Since the cables 5, which are connected to the corners of the cross member 15, are not evenly loaded when the gondola 4 is eccentrically loaded, the part of the bearing 9 belonging to the cross member 15 is mounted in a joint 26 with a horizontal axis 27 on the cross member 15. For this purpose, the cross member 15 has a recess 28 in which the bearing part associated with the cross member 15 is movably arranged, and this bearing part is suspended on a pivot pin 29 which is held on both sides in brackets 30, 31. If necessary, stops (not shown) can be provided which limit the pivoting movement about the horizontal axis 27.
