Description

Gegenstand der Erfindung sind eine Aufzugskabine mit einer Kabinenplattform, sowie ein Verfahren zur Installation eines Aufzugs, der eine erfindungsgemässe Aufzugskabine umfasst.The invention relates to an elevator car with a car platform, and a method for installing an elevator, which comprises an elevator car according to the invention.

Eine Kabinenplattform bildet die tragende Grundstruktur einer Aufzugskabine. Ihre Nutzfläche trägt die zu befördernden Passagiere oder Gegenstände und steht in einem bestimmten Verhältnis zur Nutzlast, für die die Aufzugskabine ausgelegt ist. Ausserdem kann eine Kabinenplattform unterschiedliche andere Funktionen übernehmen, wie beispielsweise die Aufnahme von Subsystemen zur Kontrolle der Bewegung der Aufzugskabine, die Aufnahme von Türführungen oder die Aufnahme von Komponenten der Aufzugssteuerung.A cabin platform forms the load-bearing basic structure of an elevator car. Your useful area carries the passengers or objects to be transported and is in a certain ratio to the payload for which the elevator car is designed. In addition, a cabin platform can perform various other functions, such as the inclusion of subsystems to control the movement of the elevator car, the inclusion of door guides or the inclusion of components of the elevator control.

Aus DE 31 34 764 ist eine Plattform für eine Aufzugskabine bekannt, die aus mindestens zwei Plattformsektionen aus Stahlblech gefertigt ist, wobei diese Plattformsektionen durch Schweissen miteinander verbunden sind. Als Vorteile dieser Bauweise sind eine einfache Herstellung und ein gegenüber Kabinenböden aus Walzprofilen reduziertes Gewicht genannt.Out DE 31 34 764 is a platform for an elevator car is known, which is made of at least two platform sections made of sheet steel, these platform sections are connected by welding together. The advantages of this design are simple production and reduced weight compared to cab floors made of rolled sections.

Eine nach der Lehre von DE 31 34 764 hergestellte Kabinenplattform weist einige Nachteile auf. Gelehrt wird ein symmetrischer Aufbau der Kabinenplattform aus jeweils zwei gleichartigen Plattformsektionen. Durch die Gleichartigkeit der Plattformsektionen ist deren Eignung, unterschiedliche Funktionen an unterschiedlichen Stellen der Aufzugskabine zu übernehmen, stark eingeschränkt.One according to the doctrine of DE 31 34 764 manufactured cabin platform has some disadvantages. It teaches a symmetrical design of the cabin platform from two similar platform sections. Due to the similarity of the platform sections their suitability to take on different functions at different locations of the elevator car is severely limited.

Die Plattformsektionen sind ausserdem fix miteinander verbunden, so dass die Kabinenplattform nach dem Herstellungsprozess eine relativ grosse Einheit bildet. Es ist entsprechend schwierig, die Kabinenplattform innerhalb eines Gebäudes zu transportieren, durch Engstellen zu manövrieren und durch Schachtöffnungen in den Aufzugsschacht zu befördern.The platform sections are also permanently connected to each other, so that the cabin platform after the manufacturing process forms a relatively large unit. It is correspondingly difficult to transport the cabin platform within a building, to maneuver through bottlenecks and to convey through manhole openings in the elevator shaft.

Aus FR 1 371 974 ist eine Aufzugskabine mit drei Plattformsektionen bekannt geworden, die miteinander verschweisst sind.Out FR 1 371 974 is an elevator car with three platform sections have become known, which are welded together.

EP 1 364 905 A1 zeigt einen Träger für eine Aufzugskabine, in welchem Umlenkrollen für Tragseile montiert sind, welcher über obere Flansche an einen Kabinenboden anbringbar ist. EP 1 364 905 A1 shows a support for an elevator car, in which deflection rollers are mounted for suspension cables, which can be attached via upper flanges to a cabin floor.

Der vorliegenden Erfindung liegt einerseits die Aufgabe zugrunde, eine Aufzugskabine zu schaffen, deren Kabinenplattform in unterschiedlichen Grössen ebenfalls aus mehreren Plattformsektionen hergestellt ist, die jedoch an unterschiedlichen Stellen der Aufzugskabine unterschiedliche Funktionen übernehmen kann. Andererseits soll auf der Basis der erfindungsgemässen Aufzugskabine ein rationelles Verfahren zur Installation eines Aufzugs definiert werden, bei dem die genannten Transportprobleme nicht auftreten.On the one hand, the object of the present invention is to provide an elevator car whose cabin platform of different sizes is also made of a plurality of platform sections, but which can assume different functions at different locations in the elevator car. On the other hand, on the basis of the elevator car according to the invention, a rational method for installing an elevator should be defined in which the said transport problems do not occur.

Die erstgenannte Aufgabe wird erfindungsgemäss dadurch gelöst, dass die Aufzugskabine eine Kabinenplattform umfasst, bei welcher an einer zentralen Plattformsektion eine frontseitige und eine rückseitige Plattformsektion angeordnet sind.The first object is achieved according to the invention in that the elevator car comprises a car platform, in which a front and a rear platform section are arranged on a central platform section.

Eine erfindungsgemässe Aufzugskabine hat den Vorteil, dass die Kabinenplattform nicht aus fest miteinander verbundenen, gleichartigen Plattformsektionen besteht, sondern, dass diese aus Plattformsektionen aufgebaut ist, die unterschiedliche Gestalt haben, um unterschiedliche, bei einer Aufzugskabine vorkommende Funktionen erfüllen zu können oder deren Realisierung zu vereinfachen.An elevator car according to the invention has the advantage that the cabin platform is not made of firmly connected, similar platform sections, but that it is constructed of platform sections that have different shapes to meet different occurring in an elevator car functions or to simplify their implementation.

Die zweitgenannte Aufgabe wird durch ein erfindungsgemässes Verfahren gelöst, bei dem bei der werksseitigen Auslieferung einer Kabinenplattform jeweils eine zentrale sowie je eine frontseitige und eine rückseitige Plattformsektion voneinander getrennt bereitgestellt werden, und bei dem bei der Montage am Installationsort des Aufzugs die voneinander getrennten Plattformsektionen der Kabinenplattform mittels Verbindungselementen miteinander verbunden werden. Vorteile aus diesem Verfahren ergeben sich insbesondere beim Transport der Kabinenplattform zum Installationsort und bei ihrer Beförderung zur Montageposition, beispielsweise in einen Aufzugsschacht eines Gebäudes.
Beim Transport können die getrennt ausgelieferten Plattformsektionen einfacher verpackt werden, und sie beanspruchen weniger Transportraum. Sie können durch das Transportpersonal ohne besondere Hilfsmittel auf- und abgeladen, innerhalb eines Gebäudes befördert und via Schachtöffnungen in einen Aufzugsschacht gebracht werden, da sie weniger wiegen und weniger sperrig sind, als eine komplette Kabinenplattform.
Bei der Montage am Installationsort des Aufzugs können die Plattformsektionen mit einfachen Hilfsmitteln in Montageposition gebracht und dort ohne grosse Anstrengung miteinander zu einer Kabinenplattform verbunden werden.The second object is achieved by a method according to the invention, in which a central and one front and one rear platform section are provided separately from each other in the factory delivery of a car platform, and in which the separate platform sections of the cabin platform during installation at the installation of the elevator be connected by means of connecting elements. Advantages of this method result in particular when transporting the cabin platform to the installation site and during its transport to the assembly position, for example in a lift shaft of a building.
During transport, the separately delivered platform sections can be packed more easily, and they require less transportation space. They can be loaded and unloaded by the transport personnel without special aids, transported inside a building and brought into a lift shaft via manhole openings, as they weigh less and are less bulky than a complete cabin platform.
When mounting at the installation of the elevator, the platform sections can be brought with simple tools in mounting position and connected there without great effort to each other to a cabin platform.

Im Folgenden wird die Erfindung sowie werden vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung beschrieben:

  • Nach einer bevorzugten Ausbildungsform der Erfindung ist die zentrale Plattformsektionen der Kabinenplattform als unteres Querjoch der Aufzugskabine ausgebildet, wobei in, bzw. an dieses Querjoch mehrere Subsysteme montiert sind, die der Funktion dienen, die Bewegung der Aufzugskabine zu erzeugen, bzw. zu kontrollieren. Vorzugsweise handelt es sich bei diesen Subsystemen um Trag- und Umlenkrollen, über die ein flexibles Tragmittel die Aufzugskabine in Form einer Kabinen-Unterschlingung trägt und antreibt, um Kabinenführungsschuhe, mit denen der untere Teil der Aufzugskabine an Führungsschienen geführt ist, um Fangvorrichtungen, die im Notfall die Aufzugskabine bremsen, und um eine Schutzraumsicherungsvorrichtung zur Gewährleistung eines Schutzraums oberhalb der Aufzugskabine. Das Konzept der aus mehreren Plattformsektionen bestehenden Kabinenplattform ermöglicht es, die zentrale Plattformsektion unabhängig von den anderen Sektionen werksseitig mit den genannten Subsystemen auszurüsten, was wesentlich zu einer Verbesserung der Montagequalität und zu einer Reduktion des Montageaufwands am Installationsort des Aufzugs beiträgt.
In the following the invention as well as advantageous refinements and developments of the invention are described:
  • According to a preferred embodiment of the invention, the central platform sections of the cabin platform is designed as a lower transverse yoke of the elevator car, wherein in or on this transverse yoke several subsystems are mounted, which serve the function of generating the movement of the elevator car, or to control. Preferably, these subsystems are support and deflection rollers, via which a flexible support means carries and drives the elevator car in the form of a cabin underrun, in order to guide car boot shoes, with which the lower part of the elevator car is guided on guide rails, around safety gears Emergency brake the elevator car, and to a protection space protection device to ensure a shelter above the elevator car. The concept of the cabin platform consisting of several platform sections makes it possible to factory-equip the central platform section independently of the other sections with the mentioned subsystems, which substantially contributes to an improvement of the assembly quality and to a reduction of the installation effort at the installation location of the elevator.

Gemäss einer weiteren bevorzugten Ausgestaltung der Erfindung sind die frontseitige Plattformsektion und die rückseitige Plattformsektion unterschiedlich gestaltet, um unterschiedliche Funktionen erfüllen zu können. Eine einer Türfront zugeordnete Plattformsektion kann beispielsweise die Funktion erfüllen, in einer Vertiefung eine Türschwelle aufzunehmen, oder Anschlusselemente zum Befestigen einer Sicherheitsschürze unterhalb der Türschwelle aufzuweisen. Eine rückseitige Plattformsektion kann beispielsweise die Funktionen erfüllen, mittels integrierten Elementen die Verbindung zwischen der Kabinenplattform und der Kabinenrückwand zu ermöglichen oder Anschlusskästen für die elektrischen Installationen der Aufzugskabine aufzunehmen und zu fixieren.According to a further preferred embodiment of the invention, the front-side platform section and the rear-side platform section are designed differently in order to be able to fulfill different functions. For example, a platform associated with a door front may perform the function of receiving a door sill in a recess, or having mounts for attaching a safety bumper beneath the sill. A rear platform section can, for example, fulfill the functions of enabling the connection between the cabin platform and the cabin rear wall by means of integrated elements or of receiving and fixing connection boxes for the electrical installations of the elevator car.

Wesentliche Vorteile bringt eine Ausführungsform der Erfindung, bei der mindestens zwei der Plattformsektionen der Kabinenplattform in parallelen vertikalen Ebenen angeordnete Verbindungsstellen aufweisen, an welchen diese Plattformsektionen mit Verbindungselementen, vorzugsweise mit Schraubverbindungen, miteinander verbunden sind.
Bei dieser Lösung werden die Plattformsektionen beim Anziehen der Verbindungselemente von selbst gegenseitig ausgerichtet. Ausserdem sind bei dieser Anordnung der Verbindungsstellen die Verbindungselemente durch die im Aufzugsbetrieb auftretenden Belastungen vorwiegend auf Zug und weniger auf Schub beansprucht, wodurch zuverlässig verhindert wird, dass die Plattformsektionen sich unter Belastung relativ zueinander verschieben.Substantial advantages is provided by an embodiment of the invention in which at least two of the platform sections of the cabin platform have connecting points arranged in parallel vertical planes, to which these platform sections are connected to one another by connecting elements, preferably with screw connections.
In this solution, the platform sections are self-aligned when tightening the fasteners. In addition, in this arrangement, the joints of the fasteners are stressed by the loads occurring in elevator operation mainly on train and less on thrust, which reliably prevents the platform sections move under load relative to each other.

Nach einer Gewicht und Kosten sparenden Erfindung sind über den beiden Seitenrändern der Kabinenplattform Plattformrandprofile angebracht, die sich über die Oberseiten der aneinander geflanschten Plattformsektionen erstrecken und mit diesen durch Verbindungselemente verbunden sind, wobei die Plattformrandprofile so dimensioniert sind, dass sie einen wesentlichen Beitrag zur Stabilisierung und zur Tragfähigkeit der Kabinenplattform leisten.
Vorteilhafterweise sind ihr Werkstoff und ihr Querschnitt so ausgewählt, dass sie gemeinsam und ohne Mitwirkung anderer Komponenten die Biegebelastung, welche die Kabinennutzlast auf die von der zentralen Plattformsektion 2 auskragenden Plattformsektionen 3, 4 ausübt, aufnehmen können und dabei eine Durchbiegung von weniger als 1 % der Länge der Plattformsektionen erfahren. Erreicht werden diese Eigenschaften der Plattformrandprofile vorzugsweise dadurch, dass diese aus Stahl oder einer Aluminiumlegierung hergestellt sind und einen Querschnitt aufweisen, der bezüglich seiner horizontalen Schwerachse mindestens ein Flächenträgheitsmoment von 50 cm4 und/oder eine Gesamthöhe von mindestens 6 cm hat.
Dank der Stabilisierung der Kabinenplattform durch die als Verbindungselement zwischen der Kabinenplattform und den Kabinenseitenwänden ohnehin erforderlichen Plattformrandprofile wird erreicht, dass die Plattformsektionen mit einfachen Formen, geringstmöglichem Herstellaufwand und minimalem Gewicht ausgeführt werden können.After a weight and cost saving invention, over the two side edges of the cabin platform platform edge profiles are mounted, which extend over the tops of the flanged platform sections and connected thereto by fasteners, the platform edge profiles are dimensioned so that they make a significant contribution to the stabilization and contribute to the load capacity of the cabin platform.
Advantageously, their material and their cross-section are selected so that they together and without the involvement of other components, the bending load which exerts the cabin payload on the projecting from the central platform section 2 platform sections 3, 4, and thereby a deflection of less than 1% of Learn the length of the platform sections. These properties of the platform edge profiles are preferably achieved in that they are made of steel or an aluminum alloy and have a cross-section having at least one area moment of inertia of 50 cm 4 and / or a total height of at least 6 cm with respect to its horizontal axis of gravity.
Thanks to the stabilization of the cabin platform by the required as a connecting element between the cabin platform and the cabin sidewalls platform edge profiles is achieved that the platform sections can be performed with simple shapes, the lowest possible manufacturing costs and minimal weight.

Gemäss einer weiteren vorteilhaften Ausgestaltung der Erfindung bilden die als Stabilisierungselemente dienenden Plattformrandprofile auch Verbindungselemente, mit denen die Seitenwände der Aufzugskabine mit der Kabinenplattform verbunden sind.
Diese Lösung ermöglicht eine stabile Verbindung zwischen den Seitenwänden der Aufzugskabine und der Kabinenplattform, wobei die Kombination der beiden Funktionen der Plattformrandprofile eine wesentliche Vereinfachung der Konstruktion der Kabinenplattform und damit erhebliche Kosteneinsparungen zur Folge haben.According to a further advantageous embodiment of the invention, the platform edge profiles serving as stabilizing elements also form connecting elements with which the side walls of the elevator car are connected to the car platform.
This solution allows a stable connection between the side walls of the elevator car and the cabin platform, wherein the combination of the two functions of the platform edge profiles have a significant simplification of the design of the cabin platform and thus significant cost savings result.

Hervorragende Flexibilität in Bezug auf die Herstellung erfindungsgemässer Kabinenplattformen wird dadurch erreicht, dass die frontseitige und/oder die rückseitige Plattformsektion als einteilige Plattformsektion ausgeführt sein können oder mehrere Teilsektionen umfassen.Excellent flexibility with respect to the production of cabin platforms according to the invention is achieved in that the front and / or the rear platform section can be designed as a one-piece platform section or comprise a plurality of subsections.

Besonders kostengünstige Kabinenplattformen ergeben sich mit einer Ausführungsform, bei der die Teilsektionen der Kabinenplattform als U-förmige Abkantprofile ausgeführt sind, die aus jeweils einem einzigen Blechstück bestehen.Particularly cost cabin platforms arise with an embodiment in which the subsections of the cabin platform are designed as U-shaped Abkantprofile, each consisting of a single piece of sheet metal.

Gemäss einer wirtschaftlich besonders interessanten Ausgestaltung des erfindungsgemässen Verfahrens zur Installation eines Aufzugs werden werksseitig an oder in der als unteres Querjoch ausgebildeten Plattformsektion Subsysteme der Aufzugskabine montiert, die der Erzeugung, bzw. der Kontrolle der Bewegung der Aufzugskabine dienen (Tragmittelrollen, Führungsschuhe, etc.). Dies ist beim erfindungsgemässen Verfahren besonders vorteilhaft zu realisieren, da die separaten Plattformsektionen dadurch nicht übermässig schwer werden. Die werksseitige Vormontage der Subsysteme trägt wesentlich zu einer Verbesserung der Montagequalität und zu einer Reduktion des Montageaufwands am Installationsort des Aufzugs bei.According to an economically particularly interesting embodiment of the inventive method for installing an elevator subsystems of the elevator car are mounted on the factory side or in the formed as a lower transverse yoke platform subsections that serve the generation, or the control of the movement of the elevator car (suspension rollers, guide shoes, etc.) , This can be realized particularly advantageously in the method according to the invention, since the separate platform sections are thereby not excessively heavy. The factory pre-assembly of the subsystems contributes significantly to an improvement of the assembly quality and to a reduction of the assembly work at the installation of the elevator.

Unter dem Begriff eines "werksseitigen" Vorgangs ist irgend ein Herstell- oder Montagevorgang zu verstehen, der vor der Auslieferung und vor der Montage am Installationsort des Aufzugs unter fabrikmässigen Bedingungen, d. h. beispielsweise in einem geeigneten Gebäude und mittels besonders geeigneten Hilfsmitteln und Einrichtungen, erfolgt.The term "factory" operation means any manufacturing or assembly operation that takes place prior to delivery and before assembly at the installation site of the elevator under factory conditions, ie. H. For example, in a suitable building and by means of particularly suitable tools and facilities occurs.

Nach dem erfindungsgemässen Verfahren werden die frontseitige Plattformsektion (3, 23) und die rückseitige Plattformsektion (4, 24) unterschiedlich gestaltet, damit diese unterschiedliche Funktionen erfüllen können.According to the method according to the invention, the front platform section (3, 23) and the rear platform section (4, 24) are designed differently so that they can fulfill different functions.

Eine besonders Kosten sparende Weiterbildung des Verfahrens besteht darin, dass die Kabinenplattform nach einem modularen Abmessungskonzept hergestellt wird, wobei die Längen der frontseitigen und rückseitigen Plattformsektionen wie auch deren Breite aus einer Anzahl von Abmessungen ausgewählt werden, die in dem modularen Abmessungskonzept definiert sind.A particularly cost-saving development of the method is that the cabin platform is produced according to a modular dimensioning concept, wherein the lengths of the front and rear platform sections as well the width of which is selected from a number of dimensions defined in the modular dimensioning concept.

Zusätzliche Kosteneinsparungen bringt eine Weiterbildung des Verfahrens, nach welcher die Längsträger, welche die Längen der jeweiligen Plattformsektionen definieren, und die Querträger, welche die Breite der Plattformsektionen definieren, unabhängig voneinander hergestellt und an Lager gehalten werden und die Vormontage der Plattformsektionen werksseitig erst aufgrund eines konkreten Auftrags mit festgelegten Kabinenabmessungen durch Kombination von vorgefertigten Längs- und Querträgern mit entsprechenden Abmessungen erfolgt.Additional cost savings brings a further development of the method, according to which the longitudinal members defining the lengths of the respective platform sections, and the cross members defining the width of the platform sections, independently manufactured and kept in stock and the pre-assembly of the platform sections factory only due to a concrete Contract with specified cabin dimensions by combination of prefabricated longitudinal and transverse beams with appropriate dimensions.

Gemäss einer besonders vorteilhaften Ausgestaltung des erfindungsgemässen Verfahrens werden vor der Montage am Installationsort des Aufzugs die Plattformsektionen der Kabinenplattform einzeln verpackt und/oder in getrenntem Zustand zum Installationsort transportiert.
Damit wird generell die Handhabung der Kabinenplattform erleichtert, die Verpackung wird vereinfacht und die separaten Plattformsektionen können beim Transport zum Installationsort mit einfacheren oder gar keinen Hilfsmitteln und in kleineren Fahrzeugen befördert werden.According to a particularly advantageous embodiment of the inventive method, the platform sections of the cabin platform are individually packed and / or transported in a separate state to the installation site prior to installation at the installation of the elevator.
This generally facilitates the handling of the cabin platform, simplifies packaging and enables the separate platform sections to be transported with easier or no tools and in smaller vehicles during transport to the installation site.

Fig. 1 zeigt in Form einer perspektivischen Explosiv-Darstellung die Struktur mit allen wesentlichen Bauteilen einer ersten Ausführungsform der Kabinenplattform 1 einer erfindungsgemässen Aufzugskabine.
Fig. 2 zeigt die Kabinenplattform 1 gemäss Fig. 1 in montiertem Zustand, in einer Seitenansicht.
Die Kabinenplattform 1 umfasst mehrere Plattformsektionen 2, 3, 4, die aus Stahlblech und Stahlplatten gefertigt sind, wobei je eine frontseitige und eine rückseitige Plattformsektion 3, 4 an einer zentralen Plattformsektion 2 angeordnet sind. Auf den in einer gemeinsamen Ebene liegenden Oberseiten der Plattformsektionen ist eine Kabinenbodenplatte 9 fixiert, die vorzugsweise als Verbundplatte ausgeführt ist. Als Kabinenbodenplatte eignen sich vorzugsweise Honigwaben-Sandwichplatten aus Aluminium oder Kunststoffen oder Holzfaserplatten mit beidseitigen metallischen Verbundschichten. Fig. 1 shows in the form of a perspective exploded view of the structure with all the essential components of a first embodiment of the cabin platform 1 of an elevator car according to the invention.
Fig. 2 shows the cabin platform 1 according Fig. 1 in assembled condition, in a side view.
The cabin platform 1 comprises a plurality of platform sections 2, 3, 4, which are made of sheet steel and steel plates, wherein each of a front and a rear platform section 3, 4 are arranged on a central platform section 2. On the lying in a common plane tops of the platform sections a cabin floor plate 9 is fixed, which is preferably designed as a composite plate. As a cabin floor plate are preferably honeycomb sandwich panels made of aluminum or plastics or wood fiber boards with double-sided metallic composite layers.

Die zentrale Plattformsektion 2 ist als in die Kabinenplattform integriertes unteres Querjoch der Aufzugskabine ausgebildet. Sie verleiht dieser die erforderliche Stabilität, wobei der Raum eingespart wird, der bei üblichen Aufzugskabinen durch ein unterhalb der Kabinenplattform vorhandenes, nicht in diese integriertes Querjoch beansprucht wird.The central platform section 2 is designed as a lower transverse yoke of the elevator car integrated into the cabin platform. It gives this the required stability, the space is saved, which is claimed in conventional elevator cars by a below the cabin platform available, not integrated into this cross yoke.

Die ein unteres Querjoch bildende zentrale Plattformsektion 2 weist unter anderem Befestigungsstellen 2.5, 2.6 für Kabinenführungsschuhe bzw. für Fangvorrichtungen auf. Es können auch Sicherheitspuffer an diesem Querjoch angebracht sein. Ausserdem sind in der das Querjoch bildenden zentralen Plattformsektion 2 Trag- und Umlenkrollen 11 integriert, über welche ein flexibles Tragmittel die Aufzugskabine trägt und bewegt. Im vorliegenden Fall weisen die Trag- und Umlenkrollen 11 in Umfangsrichtung verlaufende Rillen und Rippen auf, die mit Rippen und Rillen von als Tragmittel dienenden Keilrippenriemen zusammenwirken.The central platform section 2 forming a lower transverse yoke has, among other things, attachment points 2.5, 2.6 for cabin guide shoes or for safety gears. There may also be safety buffers attached to this cross bar. In addition, in the transverse yoke forming central platform section 2 supporting and deflection rollers 11 are integrated, via which carries a flexible support means the elevator car and moves. In the present case, the support and deflection rollers 11 in the circumferential direction extending grooves and ribs, which cooperate with ribs and grooves of serving as a support means V-ribbed belt.

In die das untere Querjoch bildende zentrale Plattformsektion 2 kann zusätzlich eine Schutzraumsicherungsvorrichtung 12 integriert sein. Diese gewährleistet durch seitliches Ausfahren einer Riegelstange 12.1, die mit einer mit einem im Aufzugschacht fix installierten Anschlag zusammenwirkt, dass beispielsweise bei einer Inspektionsfahrt ein Sicherheitsabstand zwischen dem Kabinendach und dem Schachtkopf, bzw. zwischen dem Kabinenboden und dem Boden des Aufzugschachts, nicht unterschritten werden kann.In the lower transverse yoke forming central platform section 2 may additionally be integrated into a protection space protection device 12. This ensures by lateral extension of a locking bar 12.1, which cooperates with a fixed in the hoistway stop installed, that, for example, during an inspection trip a safety distance between the cabin roof and the shaft head, or between the cabin floor and the bottom of the hoistway can not be exceeded ,

Die Plattformsektionen 2, 3, 4 weisen in parallelen vertikalen Ebenen liegende Verbindungsstellen 2.1, 3.1, 4.1 auf, an welchen jeweils zwei der Plattformsektionen mittels Verbindungselementen 10 miteinander verbunden sind. Es werden bevorzugt lösbare Verbindungselemente wie beispielsweise Schraubenverbindungen angewandt. Die Verbindung der Plattformsektionen, die erst bei der Montage am Installationsort der Aufzugsanlage erfolgt, kann jedoch auch mit nicht lösbaren Verbindungselementen, beispielsweise mit Nieten, realisiert werden.
Bei diesem Verbindungskonzept werden bei der Montage der Kabinenplattform am Installationsort des Aufzugs die jeweils zu verbindenden Plattformsektionen vorerst grob aufeinander ausgerichtet. Anschliessend werden diese mit Hilfe der Verbindungselemente im Bereich der vertikalen Verbindungsstellen aneinander gepresst, wodurch die Plattformsektionen sich selbstständig gegenseitig ausrichten. Das präzise gegenseitige Ausrichten wird dabei durch das gleichzeitige Anbringen von Plattformrandprofilen unterstützt, die nachstehend beschrieben sind.The platform sections 2, 3, 4 have connecting points 2.1, 3.1, 4.1 lying in parallel vertical planes, on each of which two of the platform sections by means of connecting elements 10 are connected to each other. There are preferably applied releasable fasteners such as screw connections. However, the connection of the platform sections, which only takes place during installation at the installation site of the elevator installation, can also be realized with non-detachable connection elements, for example with rivets.
In this connection concept, the platform sections to be connected in each case are roughly aligned with each other during assembly of the cabin platform at the installation site of the elevator. Subsequently, these are pressed together by means of the connecting elements in the region of the vertical connection points, whereby the platform sections align themselves mutually independently. The precise mutual alignment is supported by the simultaneous application of platform edge profiles, which are described below.

Alle Plattformsektionen 2, 3, 4 umfassen mindestens je zwei Längsträger 2.2, 3.2, 4.2 und mindestens je einen Querträger 2.3, 3.3, 4.3. Der Querträger 2.3 ist Teil der zentralen Plattformsektion 2, die ein in die Kabinenplattform 1 integriertes unteres Querjoch der Aufzugskabine bildet. Der Querträger 3.3 dient als Träger eines Türschwellenprofils 7 (nur in Fig. 2 dargestellt) sowie von Supporten 13 für eine Sicherheitsschürze, und ein oberer Teil des Querträgers 4.3 ist so ausgebildet, dass eine rückseitige Kabinenwand (nicht dargestellt) an ihm fixiert werden kann.All platform sections 2, 3, 4 comprise at least two longitudinal members 2.2, 3.2, 4.2 and at least one respective cross member 2.3, 3.3, 4.3. The cross member 2.3 is part of the central platform section 2, which forms an integrated into the cabin platform 1 lower cross yoke of the elevator car. The cross member 3.3 serves as a carrier of a door sill profile 7 (only in Fig. 2 shown) and supports 13 for a safety apron, and an upper part of the cross member 4.3 is formed so that a rear cabin wall (not shown) can be fixed to it.

Mit dem Bezugszeichen 8 sind zwei Plattformrandprofile bezeichnet, die bei der Montage am Installationsort des Aufzugs an Befestigungsstellen 2.4, 3.4, 4.4 der Plattformsektionen 2, 3, 4 mit letzteren verbunden werden und sich über die Oberseiten aller aneinander geflanschter Plattformsektionen erstrecken. Die genannten Befestigungsstellen an den Plattformsektionen sind so angeordnet, dass sie im montierten Zustand der Kabinenplattform 1 in deren Seitenrandbereich und in einer gemeinsamen horizontalen Ebene liegen. Die Plattformrandprofile 8 sind dabei so dimensioniert, dass sie einen wesentlichen Beitrag zur Stabilität der gesamten Kabinenplattform 1 leisten. Vorteilhafterweise sind ihr Werkstoff und ihr Querschnitt so ausgewählt, dass sie gemeinsam und ohne Mitwirkung anderer Komponenten die Biegebelastung, welche die Kabinennutzlast auf die von der zentralen Plattformsektion 2 auskragenden Plattformsektionen 3, 4 ausübt, aufnehmen können und dabei eine Durchbiegung von weniger als 1 % der Länge der jeweiligen Plattformsektionen erfahren. Erreicht werden diese Eigenschaften der Plattformrandprofile 8 vorzugsweise dadurch, dass diese aus Stahl oder einer Aluminiumlegierung hergestellt sind und einen Querschnitt aufweisen, der bezüglich seiner horizontalen Schwerachse mindestens ein Flächenträgheitsmoment von 50 cm4 und/oder eine Gesamthöhe von mindestens 6 cm hat.By the reference numeral 8, two platform edge profiles are referred to when mounting the installation site of the elevator at attachment points 2.4, 3.4, 4.4 of the platform sections 2, 3, 4 are connected to the latter and extend over the tops of all flanged platform sections. Said fastening points on the platform sections are arranged so that they lie in the assembled state of the cabin platform 1 in its side edge region and in a common horizontal plane. The platform edge profiles 8 are dimensioned so that they make a significant contribution to the stability of the entire cabin platform 1. Advantageously, their material and their cross-section are selected so that they together and without the involvement of other components, the bending load which exerts the cabin payload on the projecting from the central platform section 2 platform sections 3, 4, and thereby a deflection of less than 1% of Learn length of the respective platform sections. These properties of the platform edge profiles 8 are preferably achieved in that they are made of steel or an aluminum alloy and have a cross-section having at least one area moment of inertia of 50 cm 4 and / or a total height of at least 6 cm with respect to its horizontal axis of gravity.

Die Plattformrandprofile 8 dienen einerseits der Stabilisierung der gesamten Kabinenplattform 1, so dass die Anforderungen an die Stabilität der Plattformsektionen 2, 3, 4 entsprechend reduziert werden können. Diese können daher mit geringerem Gewicht produziert werden. Im vorliegenden Fall sind die Plattformsektionen 3 und 4 ausschliesslich aus Stahlblech von maximal 2.5 mm Dicke hergestellt. Andererseits dienen die Plattformrandprofile 8 zur Verbindung der Kabinenseitenwände (nicht dargestellt) mit der Kabinenplattform 1 und bilden dabei ein von der Kabineninnenseite her sichtbares, ästhetisch anspruchsvolles Übergangselement zwischen dem Kabinenboden und den genannten Kabinenseitenwänden.The platform edge profiles 8 on the one hand serve to stabilize the entire cabin platform 1, so that the requirements for the stability of the platform sections 2, 3, 4 can be correspondingly reduced. These can therefore be produced with less weight. In the present case, the platform sections 3 and 4 are made exclusively of sheet steel with a maximum thickness of 2.5 mm. On the other hand, the platform edge profiles 8 serve to connect the cabin side walls (not shown) to the cabin platform 1, thereby forming one from the inside of the cabin visible, aesthetically sophisticated transition element between the cabin floor and said cabin side walls.

Bei der Montage am Installationsort des Aufzugs dienen die Plattformrandprofile 8 ausserdem dazu, die Oberseiten der aneinander geflanschten Plattformsektionen 2, 3, 4 mit Hilfe der zwischen ihnen und den Plattformsektionen vorhandenen Verbindungselemente 14 genau und bündig aufeinander auszurichten.When mounting at the installation of the elevator, the platform edge profiles 8 also serve to align the tops of the flanged platform sections 2, 3, 4 with the help of existing between them and the platform sections fasteners 14 exactly and flush to each other.

In und/oder an den frontseitigen bzw. rückseitigen Plattformsektionen 3, 4 können Kabinenkomponenten wie beispielsweise ein Türschwellenprofil 7, eine Halterung 13 für eine Sicherheitsschürze unterhalb des Türschwellenprofils 7, ein Halteelement 4.3.1 für die Kabinenrückwand, Endschalter, Anschlusskästen für elektrische Systeme, Schachtbeleuchtungslampen etc. vorhanden sein. Damit die frontseitigen bzw. rückseitigen Plattformsektionen 3, 4 diese Funktionen erfüllen können, weisen sie entsprechend unterschiedliche Gestalt auf.In and / or on the front or rear platform sections 3, 4 cabin components such as a door sill profile 7, a holder 13 for a safety apron below the sill profile 7, a retaining element 4.3.1 for the cabin rear wall, limit switches, junction boxes for electrical systems, shaft lighting lamps etc. be present. So that the front or rear platform sections 3, 4 can fulfill these functions, they have correspondingly different shapes.

Die vorstehend genannten, in einer der Plattformsektionen 2, 3, 4 integrierten oder an diesen angebauten Komponenten und Subsysteme (Kabinenführungsschuhe, Fangvorrichtung, Sicherheitspuffer, Trag- und Umlenkrollen, Schutzraumsicherungsvorrichtung, Sicherheitsschürze, Endschalter, Anschlusskästen, Lampen, etc.) werden vorzugsweise bereits werksseitig vormontiert und vorzugsweise verdrahtet, um den Montageaufwand am Installationsort des Aufzugs so gering wie möglich zu halten und die Montagequalität zu optimieren. Eine erfindungsgemässe, aus mehreren Plattformsektionen aufgebaute Kabinenplattform bietet für dieses Montagekonzept ideale Voraussetzungen, da einerseits die zu transportierenden und in Montageposition zu bringenden einzelnen Plattformsektionen auch mit integrierten Subsystemen noch relativ leicht manipulierbar sind, und da andererseits die noch getrennten Plattformsektionen besser verpackt werden können, so dass die genannten Komponenten und Subsysteme ausreichend geschützt sind.The abovementioned components and subsystems integrated in or attached to one of the platform sections 2, 3, 4 (cabin guide shoes, safety gear, safety buffers, carrying and deflection rollers, protective space safety device, safety apron, limit switches, junction boxes, lamps, etc.) are preferably already factory-fitted preassembled and preferably wired in order to minimize the installation effort at the installation site of the elevator and to optimize the assembly quality. An inventive, constructed from several platform sections Cabin platform offers ideal conditions for this assembly concept, since on the one hand the individual platform sections to be transported and mounted in assembly position are relatively easy to manipulate, even with integrated subsystems, and on the other hand, the still separate platform sections can be better packed, so that the components and subsystems mentioned sufficient are protected.

Die die Längen L3, L4 der jeweiligen Plattformsektionen 3, 4 definierenden Längsträger 3.2, 4.2 und die die Breite B der Plattformsektionen 2, 3, 4 definierenden Querträger 2.3, 3.3, 4.3 werden unabhängig voneinander hergestellt und an Lager gehalten, wobei die Längen L3 und L4 wie auch die Breite B der Plattformsektionen 2, 3 und 4 entsprechend einem modularen Abmessungskonzept wählbar sind. Die werksseitige Vormontage der Plattformsektionen erfolgt erst aufgrund eines konkreten Auftrags mit definierten Kabirenabmessungen durch Kombination von Längs- und Querträgern mit entsprechenden Abmessungen.
Mit diesem Herstellungs- und Lagerkonzept können die Kosten für Produktion und Lagerhaltung der Kabinenplattformen extrem gering gehalten werden, während eine optimale Lieferbereitschaft gewährleistet bleibt.The longitudinal members 3.2, 4.2 defining the lengths L3, L4 of the respective platform sections 3, 4 and the cross members 2.3, 3.3, 4.3 defining the width B of the platform sections 2, 3, 4 are manufactured independently of each other and held in stock, the lengths L3 and L4 as well as the width B of the platform sections 2, 3 and 4 can be selected according to a modular dimensioning concept. The factory pre-assembly of the platform sections takes place only due to a specific contract with defined Kabirenabmessungen by combining longitudinal and transverse beams with appropriate dimensions.
With this manufacturing and storage concept, the costs for production and storage of the cabin platforms can be kept extremely low, while ensuring optimal readiness to deliver.

Fig. 3 zeigt eine Seitenansicht einer zweiten Ausführungsform einer Kabinenplattform 21 der erfindungsgemässen Aufzugskabine.
Fig. 4 zeigt eine Ansicht dieser Kabinenplattform 21 in deren Längsrichtung A und einen Querschnitt durch die Kabinenplattform an der in Fig. 3 mit II - II bezeichneten Schnittstelle. Fig. 3 shows a side view of a second embodiment of a cabin platform 21 of the elevator car according to the invention.
Fig. 4 shows a view of this cabin platform 21 in the longitudinal direction A and a cross section through the cabin platform at the in Fig. 3 with II - II designated interface.

Auch diese Ausführungsart einer erfindungsgemässen Kabinenplattform 21 umfasst mehrere Plattformsektionen 22, 23, 24, wobei je eine frontseitige und eine rückseitige Plattformsektion 23, 24 an einer zentralen Plattformsektion 22 angeordnet sind. Die frontseitige und die rückseitige Plattformsektion 23, 24 sind vorzugsweise aus mehreren Teilsektionen 23a, 23b, 24a, 24b aufgebaut.
Die Teilsektionen 23a, 23b, 24a, 24b der frontseitigen und rückseitigen Plattformsektionen 23, 24 sind als im Wesentlichen U-förmige Abkantprofile ausgeführt und jeweils durch paralleles Abkanten aus einem einzigen Blechstück erzeugt. Dabei wirken die vertikal angeordneten Schenkel der U-förmigen Abkantprofile einerseits als Querversteifungen der Kabinenplattform, und andererseits bilden sie in vertikalen Ebenen angeordnete Verbindungsstellen 22.1, 23.1, 24.1, an welchen die Teilsektionen mittels Verbindungselementen 30 miteinander verbunden sind, und die auch als Verbindungsstellen zwischen der zentralen Plattformsektion 2 und der frontseitigen, bzw. rückseitigen Plattformsektion 23, 24 dienen. Frontseitige und rückseitige Plattformsektionen von geringer Länge können auch nur ein einziges U-förmiges Abkantprofil umfassen.This embodiment of a cabin platform 21 according to the invention also comprises a plurality of platform sections 22, 23, 24, one front and one rear platform section 23, 24 being arranged on a central platform section 22. The front and rear platform sections 23, 24 are preferably constructed of a plurality of subsections 23a, 23b, 24a, 24b.
The subsections 23a, 23b, 24a, 24b of the front and rear platform sections 23, 24 are designed as substantially U-shaped folding profiles and are each produced by parallel folding from a single piece of sheet metal. The vertically arranged legs of the U-shaped Abkantprofile act on the one hand as transverse reinforcements of the cabin platform, and on the other hand they form arranged in vertical planes connecting points 22.1, 23.1, 24.1, to which the subsections are interconnected by means of connecting elements 30, and also as junctions between the central platform section 2 and the front or rear platform section 23, 24 serve. Short and short length front and rear platform sections may also comprise only a single U-shaped folding profile.

Die zentrale Plattformsektion 22 ist wie bei der ersten Ausführungsform als in die Kabinenplattform 21 integriertes unteres Querjoch der Aufzugskabine ausgeführt und ausschliesslich aus Stahlblech gefertigt. Diese Plattformsektion 22 weist ebenfalls Befestigungsstellen für Kabinenführungsschuhe und Fangvorrichtungen auf, wie das in Fig. 1 gezeigte untere Querjoch. Diese Befestigungsstellen sind hier jedoch nicht gezeigt, um die Darstellung der besonders einfachen Struktur der Plattformsektionen nicht zu beeinträchtigen.
Die frontseitige und die rückseitige Plattformsektion 23, 24 können von unterschiedlicher Gestalt sein, um unterschiedliche Funktionen und Anforderungen zu erfüllen oder unterschiedliche Positionen der zentralen Plattformsektion zu ermöglichen. Sie können beispielsweise so geformt (abgekantet) sein, dass sie ein Türschwellenprofil 27 aufnehmen können, oder dass in ihren Blechkörper ein Befestigungselement 24b.1 zum Fixieren der Kabinenrückwand integriert ist. Unterschiedliche Abmessungen der Kabinenplattform 21 werden durch Anpassung der Längen L 24, L 25 der an die zentrale Plattformsektion 22 (Querjoch) angeflanschten Plattformsektionen 23, 24, bzw. deren Teilsektionen 23a, 23b, 24a, 24b realisiert. Unterschiedliche Breiten B werden durch Verwendung von unterschiedlich breiten Stahlblechen für die Herstellung der Plattformsektionen 22, 23, 24, bzw. 22, 23a, 23b, 24a, 24b erreicht.As in the first embodiment, the central platform section 22 is designed as a lower transverse yoke of the elevator car, which is integrated into the cabin platform 21, and is manufactured exclusively from sheet steel. This platform section 22 also has attachment points for cabin guide shoes and safety gear, as in Fig. 1 shown lower cross yoke. However, these attachment points are not shown here to the representation of the particular simple structure of the platform sections not to be affected.
The front and rear platform sections 23, 24 may be of different shapes to accommodate different functions and requirements or to allow different positions of the central platform section. They may for example be shaped (folded) so that they can receive a door sill profile 27, or that in their sheet metal body, a fastening element 24b.1 is integrated for fixing the cabin rear wall. Different dimensions of the cabin platform 21 are realized by adapting the lengths L 24, L 25 of the platform sections 23, 24 flanged to the central platform section 22 (transverse yoke) or their subsections 23a, 23b, 24a, 24b. Different widths B are achieved by using steel sheets of different widths for the production of the platform sections 22, 23, 24 and 22, 23a, 23b, 24a, 24b, respectively.

Auch bei dieser Kabinenplattform 21 können alle im Zusammenhang mit der ersten Ausführungsform erwähnten Subsysteme und Komponenten in die Plattformsektionen 22, 23, 24 integriert oder an diesen angebaut werden, wobei der Einbau bzw. der Anbau der Subsysteme als werksseitige Vormontage in die voneinander getrennten Plattformsektionen erfolgt.In this cabin platform 21 as well, all subsystems and components mentioned in connection with the first embodiment can be integrated into or attached to the platform sections 22, 23, 24, the installation or fitting of the subsystems taking place as a factory pre-assembly into the separate platform sections ,

Wie vorstehend erwähnt, sind die an die zentrale Plattformsektion 22 angeflanschten Plattformsektionen 23, 24, bzw. deren Teilsektionen 23a, 23b, 24a, 24b bei dieser Ausführungsform der Kabinenplattform aus jeweils einem einzigen Blechteil gefertigt, dessen U-förmige Gestalt durch einfaches paralleles Abkanten erzeugt wird. Alle Plattformsektionen, bzw. Teilsektionen weisen vertikal orientierte Stege auf, die in Querrichtung der Kabinenplattform 21 verlaufen und der Kabinenplattform in Querrichtung ausreichende Stabilität verleihen. Um die Lage der freien unteren Enden der vertikalen Stege zusätzlich zu fixieren, können diese beispielsweise mittels eines Hilfsprofils 31 miteinander verbunden werden. Die Montage dieses Hilfsprofils 31 erfolgt erst am Installationsort des Aufzugs.As mentioned above, the platform sections 23, 24 or their subsections 23a, 23b, 24a, 24b flanged to the central platform section 22 are each made in this embodiment of the cabin platform from a single sheet metal part whose U-shaped configuration is produced by simple parallel folding becomes. All platform sections, or subsections have vertically oriented webs which extend in the transverse direction of the cabin platform 21 and give the cabin platform sufficient stability in the transverse direction. In order to fix the position of the free lower ends of the vertical webs in addition, they can be connected to each other, for example by means of an auxiliary profile 31. The installation of this auxiliary profile 31 takes place only at the installation of the elevator.

Wie aus Fig. 3 leicht erkennbar ist, bieten die aus relativ dünnen und in Querrichtung abgekanteten Blechprofilen aufgebauten Plattformsektionen keine für eine Kabinenplattform ausreichende Biegestabilität in deren Längsrichtung. Auch bei der hier beschriebenen Ausführungsform einer Kabinenplattform'21 wird daher die für den Aufzugsbetrieb erforderliche Stabilität der Kabinenplattform in Längsrichtung dadurch gewährleistet, dass bei der Montage am Installationsort zwei ausreichend stabile Plattformrandprofile 28 mit den in einer gemeinsamen Ebene liegenden Oberseiten aller Plattformsektionen 22, 23, 24 verbunden werden.How out Fig. 3 easily recognizable, the platform sections constructed from relatively thin and transversely folded sheet-metal profiles do not provide sufficient bending stability in their longitudinal direction for a cabin platform. In the embodiment of a cabin platform 21 described here, too, therefore, the stability of the cabin platform in the longitudinal direction required for the lift operation is ensured by two sufficiently stable platform edge profiles 28 with the upper sides of all platform sections 22, 23, 24 are connected.

Auch bei dieser Ausführungsform dienen die Plattformrandprofile 28 zusätzlich als Verbindungselement zwischen den Kabinenseitenwänden (nicht dargestellt) und der Kabinenplattform 21. Um die Plattformrandprofile 28, die hier einen Rechteckquerschnitt aufweisen, sowohl mit den Plattformsektionen 22, 23, 24 als auch mit den Seitenwänden verbinden zu können, sind die Plattformrandprofile 28 auf ihrer ganzen Länge mit mehreren T-förmigen Nuten 32 versehen. Bei der Montage der Kabinenplattform 21 am Installationsort werden Schraubenköpfe oder Schraubenmuttern mit geeigneter Form in diese T-förmigen Nuten 32 eingeführt und mit den Plattformsektionen und den Seitenwänden verschraubt.Also in this embodiment, the platform edge profiles 28 serve additionally as a connecting element between the cabin side walls (not shown) and the cabin platform 21. To the platform edge profiles 28, which here have a rectangular cross-section, connect both with the platform sections 22, 23, 24 and with the side walls can, the platform edge profiles 28 are provided over their entire length with a plurality of T-shaped grooves 32. When assembling the cabin platform 21 at the installation site, screw heads or nuts with suitable shape in introduced these T-shaped grooves 32 and bolted to the platform sections and the side walls.

Mit der Ausnahme, dass bei dieser zweiten Ausführungsform die Plattformsektionen keine Querträger umfassen und solche daher nicht separat hergestellt und an Lager gehalten werden, gelten alle im Zusammenhang mit der ersten Ausführungsform genannten Eigenschaften und Vorteile der Kabinenplattform sowie die Merkmale und Vorteile des Verfahrens zur Installation eines Aufzugs auch für die hier beschriebene zweite Ausführungsform.With the exception that in this second embodiment, the platform sections do not comprise cross members and therefore are not separately manufactured and stocked, all the features and benefits of the cabin platform mentioned in connection with the first embodiment and the features and advantages of the method for installing a Elevator also for the second embodiment described here.
