Description

Boden für eine Aufzugskabine  Floor for an elevator car
Die Erfindung betrifft einen Boden für eine Aufzugskabine gemäss dem Oberbegriff von Anspruch 1. Weiterhin betrifft die Erfindung einen Aufzug mit einer Aufzugskabine enthaltend einen solchen Boden. The invention relates to a floor for an elevator car according to the preamble of claim 1. Furthermore, the invention relates to an elevator with an elevator car containing such a floor.
Aufzugskabinen werden zum Beispiel in Kabinenrahmen eingebaut, die ihrerseits in Liftschächten befestigten Schienen geführt und von Antriebsmaschinen über Drahtseile oder anderen Tragmitteln auf- und ab bewegt werden. Biegesteife oder gegenüber anderen mechanischen Einwirkungen stabile Kabinenböden können in Verbundstruktur- oder Sandwich-Bauweise ausgeführt werden. Ein derartiger "Sandwich"-Boden ist beispielsweise aus der EP 1 004 538 Bl bekannt geworden. Der Boden besteht im Wesentlichen aus zwei voneinander beabstandeten Stahlplatten einer Grundstruktur, zwischen welchen eine Stützstruktur angeordnet ist. Die Stützstruktur ist aus einer Vielzahl von sich kreuzenden Flachprofilen zusammengesetzt, die eine gitterrostartige Verbundstruktur bilden. In der Praxis hat sich gezeigt, dass dieser biegesteife Boden zwar sehr hohen mechanischen Belastungen standhält, jedoch vergleichsweise teuer und schwer ist. Elevator cabs are installed, for example, in cabin frames, which in turn are guided in rails fastened to lift shafts and moved up and down by drive machines via wire ropes or other suspension means. Rigid or other mechanical effects stable cabin floors can be performed in composite or sandwich construction. Such a "sandwich" bottom has become known, for example, from EP 1 004 538 B1. The bottom consists essentially of two spaced-apart steel plates of a basic structure, between which a support structure is arranged. The support structure is composed of a plurality of intersecting flat profiles, which form a lattice-like composite structure. In practice, it has been shown that this rigid floor withstands very high mechanical loads, but is comparatively expensive and heavy.
Es ist deshalb eine Aufgabe der vorliegenden Erfindung, die Nachteile des Bekannten zu vermeiden, und insbesondere einen Boden der eingangs genannten Art zu schaffen, der einfach und kostengünstig herstellbar ist. Weiterhin soll der Boden sich durch ein geringes Gewicht auszeichnen. It is therefore an object of the present invention to avoid the disadvantages of the known, and in particular to provide a floor of the type mentioned, which is simple and inexpensive to produce. Furthermore, the floor should be characterized by a low weight.
Erfmdungsgemäss werden diese Aufgaben mit einem Boden mit den Merkmalen des Anspruchs 1 gelöst. Der erfindungsgemässe biegesteife Boden weist eine vorzugsweise metallische Grundstruktur auf, in dem eine Bodenplatte zum Vorgeben einer Standfläche für Passagiere befestigbar oder befestigt ist. In der Grundstruktur ist eine Stützstruktur angeordnet, die im Wesentlichen aus einem nichtmetallischen Werkstoff besteht. Durch die Verwendung nichtmetallischer Werkstoffe lässt sich das Gesamtgewicht für die Aufzugskabine erheblich reduzieren. Der Boden kann - ähnlich wie in der vorgängig erwähnten EP 1 004 538 Bl - eine flächige Unterseite und eine in einem Abstand zur Unterseite angeordnete flächige Oberseite aufweisen, wobei zwischen Ober- und Unterseite die Stützstruktur etwa sandwichartig angeordnet oder aufgenommen ist. Zum Beispiel kön- nen an den vorzugsweise metallischen Platten für Ober- und Unterseite vier Seitenwandabschmtte rechtwinklig anschliessen, mit welchen der Boden verschlossen ist. Ober- und Unterseite sowie die Seitenwandabschmtte können aus Platten aus Stahlblechen gefertigt sein. Selbstverständlich sind neben der vorgängig beschriebenen quaderförmigen Grundstruktur mit Ober- und Unterseite sowie den vier Seitenwandabschnitten auch andere Formgebungen und Bauweisen für Grundstrukturen zum Fixieren der Stützstruktur denkbar. Beispielsweise könnte der Boden in einem Metallrahmen oder in einer Fachwerk- Struktur eingefasst sein. According to the invention, these objects are achieved with a floor having the features of claim 1. The flexurally rigid base according to the invention has a preferably metallic basic structure in which a base plate can be fastened or fastened for prescribing a footprint for passengers. In the basic structure, a support structure is arranged, which consists essentially of a non-metallic material. By using non-metallic materials, the total weight for the elevator car can be significantly reduced. Similar to the previously mentioned EP 1 004 538 B1, the floor may have a flat underside and a flat upper surface arranged at a distance from the lower side, wherein the support structure is approximately sandwiched or received between the upper and lower sides. For example, NEN on the preferably metallic plates for top and bottom four Seitenwandabschmtte connect at right angles, with which the bottom is closed. The top and bottom as well as the Seitenwandabschmtte can be made of plates made of steel sheets. Of course, in addition to the above-described cuboid basic structure with top and bottom and the four side wall sections, other shapes and designs for basic structures for fixing the support structure are conceivable. For example, the floor could be enclosed in a metal frame or in a truss structure.
In einer ersten Ausführungsform kann die Stützstruktur aus einem Kunststoff, einem Kunststoff-Laminat oder einem auf Holz basierenden Werkstoff bestehen. Von der Erfindung werden auch Kombinationen der erwähnten Materialien erfasst. Die Materialien können weiter mit Verstärkungen durchsetzt sein oder Verstärkungen aufweisen. So könnte die Stützstruktur beispielsweise aus einem faserverstärkten Kunststoff bestehen. Als auf Holz basierende Werkstoffe kommen Holz, Sperrholz, Schichtholz, Holzspanwerkstoffe, Holzfaserwerkstoffe und Verbundwerkstoffe in Frage. Die Stützstruktur muss nicht zwingend vollständig aus den erwähnten Materialien bestehen. Beispielsweise könnte aufgebaute Stützstruktur aus Holz auch metallische Befestigungsmittel wie Nägel, Schrauben, etc. enthalten. In dieser Ausführung lassen sich auf einfache Art und Weise Kosten und Gewicht für den Boden reduzieren. In a first embodiment, the support structure may consist of a plastic, a plastic laminate or a wood-based material. Combinations of the mentioned materials are also covered by the invention. The materials may be further interspersed with reinforcements or have reinforcements. For example, the support structure could consist of a fiber-reinforced plastic. Wood-based materials include wood, plywood, plywood, chipboard, wood fiber materials and composites. The support structure does not necessarily have to consist entirely of the materials mentioned. For example, constructed support structure made of wood could also contain metallic fasteners such as nails, screws, etc. In this design, costs and weight for the floor can be reduced in a simple manner.
Für eine einfache Handhabung und Herstellbarkeit kann es vorteilhaft sein, wenn die Stützstruktur ein einziges Stützelement oder mehrere nebeneinander liegende Stützelemente umfasst. Dabei kann bzw. können das eine Stützelement oder die nebeneinander liegenden Stützelemente im Wesentlichen die gesamte Bodenfläche einnehmen. Für gewisse Anwendungen wären sogar auch bloss Teilbereiche abdeckende Stützstrukturen denkbar; zum Beispiel könnte das Stützelement lediglich die Hälfte der Bodenfläche in der Draufsicht einnehmen. For ease of handling and manufacturability, it may be advantageous if the support structure comprises a single support element or a plurality of adjacent support elements. In this case, the one or more support elements or the adjacent support elements can occupy substantially the entire floor surface. For certain applications even support structures covering only partial areas would be conceivable; For example, the support member could occupy only half of the floor surface in plan view.
Die Stützstruktur kann wenigstens ein einstückig ausgestaltetes Stützelement umfassen. Dieses Stützelement kann vorfabriziert werden und dann in wenigen Arbeitsschritten in den Boden verbaut werden. Das einstückige Stützelement kann monolithisch aufgebaut sein und beispielsweise mittels Umform-, Press- und/oder Giessverfahren geschaffen werden. Kunststoff-Stützstrukturen können beispielsweise bei Verwendung geeigneter Kunststoffe (z.B. thermoplastische Kunststoffe wie PP, PU, PE, etc.) besonders einfach im Spritzgiessverfahren hergestellt werden. Vorstellbar ist aber auch für die Stützstrukturen flächige Zuschnitte oder Kunststoffplatten zu verwenden, die plastisch in die gewünschte Form gebracht werden (Umformen). Der monolithische Formkörper könnte auch aus verpressten und verleimten Holzspänen bestehen. The support structure may comprise at least one integrally configured support element. This support element can be prefabricated and then installed in a few steps in the ground. The one-piece support element can be monolithic and be created for example by means of forming, pressing and / or casting. Plastic support structures, for example, when using suitable Plastics (eg thermoplastics such as PP, PU, PE, etc.) are particularly easy to produce by injection molding. However, it is also conceivable to use flat blanks or plastic plates for the support structures, which are plastically brought into the desired shape (forming). The monolithic molded body could also consist of compressed and glued wood chips.
Besonders bevorzugt kann das Stützelement einen flächigen Bodenabschnitt aufweisen, an dem Vorsprünge angeformt oder befestigt sind. Die Vorsprünge können den Abstand zwischen Ober- und Unterseite des Bodens überbrücken, was sich vorteilhaft auf das Gewicht und die Stabilität des Bodens auswirkt. Die Vorsprünge können vorzugsweise zusammen mit dem Bodenabschnitt integrierende Bestandteile eines monolithischen Formkörpers sein. Anstatt den angeformten Vorsprüngen können die Vorsprünge aber auch aus separaten Bauteilen bestehen, die mit geeigneten Befestigungsmitteln mit dem Bodenabschnitt verbunden sind. Particularly preferably, the support element may have a flat bottom portion on which projections are integrally formed or fixed. The projections can bridge the distance between the top and bottom of the soil, which has an advantageous effect on the weight and the stability of the soil. The protrusions may preferably be integrating constituents of a monolithic molded body together with the bottom section. But instead of the molded projections, the projections may also consist of separate components, which are connected by suitable fastening means to the bottom portion.
Die vorerwähnten Vorsprünge können beispielsweise als Standfüsse ausgebildet sein, die in der Draufsicht vorzugsweise gleichmässig auf der Bodenabschnittsfläche verteilt sind und auf einer ebenen Unterlage abstützbar wären. The aforesaid projections may for example be formed as feet, which are preferably evenly distributed in the plan view of the bottom portion surface and would be supported on a flat surface.
Besonders vorteilhaft sind die Vorsprünge becherförmig ausgestaltet, wodurch Stützelemente vor dem Einbau in den Boden gestapelt werden können. Auf diese Weise lassen sich diese Halbfabrikate einfach und günstig lagern und transportieren. Weiterhin ergeben sich dank den Vorsprüngen im verbauten Zustand vorteilhafte Hohlräume und das Gesamtgewicht für Kabinenböden lässt sich weiter reduzieren. Particularly advantageously, the projections are designed cup-shaped, whereby support elements can be stacked before installation in the ground. In this way, these semi-finished products can be easily and conveniently stored and transported. Furthermore, thanks to the projections in the installed state advantageous cavities and the total weight for cabin floors can be further reduced.
Die becherförmigen Vorsprünge können konisch verlaufende, seitliche Stützwandabschnitte aufweisen. An dem oder den jeweiligen Stützwandabschnitten eines Vorsprungs schliesst ein Stützbodenabschnitt an, der vorzugsweise planparallel zum Bodenabschnitt verläuft. The cup-shaped projections may have conically extending lateral support wall sections. At the one or more support wall portions of a projection, a support bottom portion adjoins, which preferably extends plane-parallel to the bottom portion.
Alternativ zu den vorgängig beschriebenen Standfüssen könnte das Stützelement auch mit Kufen versehen sein. Beispielsweise könnte das Stützelement eine mittlere und zwei seitliche Kufen aufweisen. Die Kufen könnten dabei jeweils flache Profile umfassen, die über Abstandelemente mit dem Bodenabschnitt verbunden wären. Der Bodenabschnitt kann plattenförmig ausgestaltet sein. Die Platte kann zur weiteren Gewichtsreduktion Unterbrechungen aufweisen. Die Unterbrechungen können in der Draufsicht beispielsweise rechteckig sein oder eine Wabenstruktur formen. As an alternative to the feet previously described, the support element could also be provided with runners. For example, the support element could have a middle and two lateral runners. The skids could each comprise flat profiles, which would be connected by spacer elements with the bottom portion. The bottom portion may be configured plate-shaped. The plate may have interruptions for further weight reduction. The interruptions may, for example, be rectangular in plan view or form a honeycomb structure.
Der Bodenabschnitt kann eine Oberfläche aufweisen, die vorzugsweise planparallel zur Standfläche für die Passagiere verläuft. Theoretisch könnte die Standfläche auch durch den Bodenabschnitt selbst gebildet werden. In diesem Fall würden die Passagiere eines Aufzugs also direkt auf dem Stützelement stehen. The bottom portion may have a surface which is preferably plane-parallel to the footprint for the passengers. Theoretically, the footprint could also be formed by the bottom section itself. In this case, the passengers of an elevator would thus stand directly on the support element.
Die auf einer Seite offenen und auf der gegenüberliegenden Seite einen Stützbodenabschnitt aufweisenden becherförmigen Vorsprünge können derart am Bodenabschnitt angeformt oder befestigt sein, dass die offene Seite der Vorsprünge an den Bodenabschnitt anschliesst und so eine einfache Stapelung mehrerer Stützkörper aufeinander zulässt. The cup-shaped projections which are open on one side and have a support bottom section on the opposite side can be formed or fastened to the bottom section in such a way that the open side of the projections adjoins the bottom section and thus permits a simple stacking of a plurality of supporting bodies.
Die Grundstruktur kann als Fachwerk ausgestaltet sein. Mit dieser Variante kann eine weitere Gewichtsreduktion erreicht werden. Selbstverständlich sind aber auch andere Gestaltungsmöglichkeiten vorstellbar. So könnte die Grundstruktur für sehr hohe statische und dynamische Anforderungen als massiv ausgeführte Stahlkonstruktion gewählt werden. Die Grundstruktur kann weiterhin beispielsweise als seitlich die Stützstruktur umfassender Halterahmen ausgeführt sein. The basic structure can be designed as a framework. With this variant, a further weight reduction can be achieved. Of course, other design options are conceivable. Thus, the basic structure for very high static and dynamic requirements could be chosen as solid steel construction. The basic structure can furthermore be designed, for example, as a holding frame that encompasses the support structure laterally.
In einer weiteren Ausführungsform kann der Boden eine Grundstruktur mit in Längsrichtung verlaufenden Längsträgern und rechtwinklig zu den Längsträgern verlaufende Querträgern aufweisen, die miteinander verbunden sind. In a further embodiment, the floor may have a basic structure with longitudinal members extending in the longitudinal direction and transverse members extending at right angles to the longitudinal members, which are connected to one another.
Die Stützstruktur kann form- und/oder kraftschlüssig mit der Grundstruktur verbunden sein. Zur Fixierung der Stützstruktur in der Grundstruktur können aber auch Befestigungsmittel wie etwa Schraubverbindungen eingesetzt werden. Denkbar wäre auch, die Stützstruktur mit einer Klebeverbindung in der Grundstruktur zu fixieren. The support structure may be positively and / or non-positively connected to the basic structure. For fixing the support structure in the basic structure but also fasteners such as screw can be used. It would also be conceivable to fix the support structure with an adhesive bond in the basic structure.
Die Grundstruktur kann im Querschnitt U-fömige Schienenprofile mit zu den Vorsprüngen komplementären Vertiefungen enthalten, in welche die Vorsprünge zur lagemässigen Fixierung des Stützelements im Boden aufgenommen sind. Die Vertiefungen können als in Längsrichtung verlaufender Führungskanäle ausgestaltet sein. Diese Ausgestaltung hat insbesondere auch herstellungstechnische Vorteile, da die Stützstruktur einfach eingebracht und dann entlang der Führungskanäle in Längsrichtung verschoben werden kann. Die Schienenprofile können einfach in bzw. an der Grundstruktur befestigt werden. Anstatt derartiger separater Bauteile könnten die Vertiefungen auch als Führungsnuten ausgestaltet sein, die integrierender Bestandteil der Unterseite des Bodens der Kabine des Aufzugs sein könnten. Alternativ zu den kanalartigen Vertiefungen könnten aber auch einzelne Vertiefungen vorgesehen werden, die eine allseitig passgenaue Aufnahme der Vorsprünge ermöglichen. The basic structure may include in cross-section U-shaped rail profiles with recesses complementary to the projections, in which the projections for the positional fixing of the support element are received in the ground. The wells can as be configured in the longitudinal direction of the guide channels. This embodiment also has manufacturing advantages, in particular, since the support structure can be easily inserted and then displaced along the guide channels in the longitudinal direction. The rail profiles can be easily mounted in or on the basic structure. Instead of such separate components, the recesses could also be designed as guide grooves, which could be an integral part of the underside of the floor of the car of the elevator. As an alternative to the channel-like recesses, however, it would also be possible to provide individual recesses which make it possible to receive the projections on all sides in a precisely fitting manner.
Ein zweiter Aspekt der Erfindung betrifft ein Boden für eine Aufzugskabine, in dem zur Verstärkung des Bodens eine Stützstruktur integriert ist, wobei die Stützstruktur wenigstens ein zur Lagerung und Transport von Gütern vorgesehenes Palett enthält. Die eingangs aufgeführten Aufgaben werden also auch mit dem hier beschriebenen Boden mit dem Palett gelöst. Das Palett kann das vorgängig beschriebene Stützelement bilden. Die allgemein auch unter der Bezeichnung "Ladungsträger" bekannten Palette sind in der Transportindustrie weit verbreitet und gebräuchlich. Güter werden in grossem Umfang auf solchen Paletten in Lastwagen, Zügen, Flugzeugen oder Schiffen verladen und transportiert. Die Palette sind derart ausgestaltet, dass sie beispielsweise mittels Hubwagen oder Gabelstaplern einfach bewegt werden können. Uberaschenderweise hat sich gezeigt, dass solche Palette auch in der Aufzugsindustrie verwendet werden können. Durch den Einsatz von Paletten in Kabinenböden lassen sich die Kosten erheblich reduzieren, insbesondere wenn handelsübliche Palette verwendet werden. Je nach Ausgestaltung des Bodens können die Palette unverändert oder allenfalls mit kleinen Anpassungen verwendet werden. Tests haben gezeigt, dass auch derartige Kabinenböden die Anforderungen an Steifheit und Stabilität in vielen Anwendungsgebieten erfüllen können. A second aspect of the invention relates to a floor for an elevator car in which a support structure is integrated for reinforcing the floor, the support structure containing at least one pallet provided for the storage and transport of goods. The tasks listed above are thus solved with the soil described here with the pallet. The pallet may form the support element described above. The generally known as "load carriers" range are widely used in the transport industry and in use. Goods are loaded and transported to a large extent on such pallets in trucks, trains, aircraft or ships. The pallet are designed so that they can be easily moved, for example by means of trucks or forklifts. Surprisingly, it has been found that such pallets can also be used in the elevator industry. By using pallets in cabin floors, the costs can be significantly reduced, especially when commercial pallets are used. Depending on the design of the floor, the pallet can be used unchanged or at most with small adjustments. Tests have shown that even such cabin floors can meet the requirements for rigidity and stability in many fields of application.
Palette können aus unterschiedlichen Materialien bestehen, wobei Holzpalette (z. B. statt vieler: Euro- oder EUR-Palett) stark verbreitet sind. Besonders vorteilhaft ist es jedoch, wenn die Stützstruktur wenigstens ein Kunststoffpalett enthält. Kunststoffpalette haben neben dem geringen Gewicht auch den Vorteil, dass sie in unzähligen Grössen und Formen erhältlich sind und dennoch mechanischen Belastungen ausreichend standhalten. Kunststoffpalette mit Standfüssen werden beispielsweise in der DE 10 2009 041 436 AI beschrieben. Aber auch Kunststoffpalette mit Kufen in der Art von klassischen Holzpalet- tem könnten verwendet werden. Ein derartiges Palett ist beispielsweise aus der US 2003/0110990 AI bekannt geworden. Pallets can be made of different materials, with wooden pallets (eg instead of many: euro or EUR pallet) being widely used. However, it is particularly advantageous if the support structure contains at least one plastic pallet. Plastic pallets in addition to the low weight also have the advantage that they are available in countless sizes and shapes and yet sufficiently withstand mechanical stress. Plastic pallet with feet are described for example in DE 10 2009 041 436 AI. But also plastic pallets with runners in the style of classic wooden palette could be used. Such a pallet has become known, for example, from US 2003/0110990 AI.

Figur 1 zeigt einen insgesamt mit 1 bezeichneten Aufzug mit einer an Tragmitteln 4 befestigten Kabine 3. Der Schacht ist mit strichlierten Linien 2 angedeutet. Solche oder ähnliche Aufzüge sind seit langer Zeit bekannt und gebräuchlich. Anstatt dem im Ausführungsbeispiel gemäss Figur 1 beispielhaft gezeigten Tragseilen 4 kommen auch andere Tragmittel wie etwa einzelne oder mehrere Tragbänder oder -riemen aus unterschiedlichen Materialien und Zusammensetzungen in Frage. Die Aufzugskabine verfügt über einen besonderen biegesteifen Kabinenboden 5. Zusammensetzung und Aufbau des Kabinenbodens wird nachfolgend anhand der Figuren 2 bis 12 im Detail beschrieben. FIG. 1 shows a lift designated as a whole by 1 with a cab 3 fastened to support means 4. The shaft is indicated by dashed lines 2. Such or similar elevators have been known and used for a long time. Instead of the supporting cables 4 shown by way of example in the exemplary embodiment according to FIG. 1, other suspension means, such as individual or several carrier tapes or belts made of different materials and compositions, are also suitable. The elevator car has a special, rigid cabin floor 5. The composition and construction of the cabin floor will be described in detail below with reference to FIGS. 2 to 12.
Wie aus Figur 2 hervorgeht, ist im Boden 5 ein einzelnes Stützelement 6 als Stützstruktur angeordnet. Erkennbar sind in Figur 2 weiterhin eine als Platte ausgestaltete Unterseite 8, auf welcher sich das Stützelement 6 abstützt. Seitlich ist der Boden 5 durch vier etwa senkrecht verlaufende Seitenwandabschnitte 10, 11 verschlossen. Das Stützelement 6 ist damit in einer im Wesentlichen quaderförmigen Grundstruktur eingeschlossen. Die Unterseitenplatte 8 kann aus Stahl bestehen; ebenso können die vier Seitenwandabschnitte 10 und 11 aus einem Stahlblech gefertigt sein. Standfläche für Passagiere bildet vorliegend eine mit 7 bezeichnete Bodenplatte. Die Seitenwandabschnitte 10 und 11 für den Boden 5 schliessen ersichtlicherweise bündig an die jeweilige Kabinenseitenwand 12 an. As is apparent from Figure 2, a single support member 6 is arranged as a support structure in the bottom 5. Recognizable in Figure 2 also designed as a plate bottom 8, on which the support member 6 is supported. Laterally, the bottom 5 is closed by four approximately perpendicular side wall sections 10, 11. The support member 6 is thus enclosed in a substantially cuboidal basic structure. The bottom plate 8 may be made of steel; Similarly, the four side wall portions 10 and 11 may be made of a steel sheet. Stand area for passengers in the present case forms a designated 7 base plate. The side wall sections 10 and 11 for the bottom 5 obviously close to the respective cabin side wall 12 flush.
Figur 3 zeigt eine perspektivische Darstellung des Stützelements 6 für den Aufzugskabinenboden. Das Stützelement 6 weist einen flächigen Bodenabschnitt 14 und neun daran angeformte Vorsprünge 13 auf. Dieses Stützelement ist als einstückiger Formkörper ausgestaltet. Eine solche Stützstruktur kann aus unterschiedlichen Kunststoffen, jedoch bevorzugt thermoplastischen Kunststoffen (z.B. PU, PP, PE) hergestellt werden. Im vorliegenden Ausführungsbeispiel gemäss Figur 3 handelt es sich beim Stützkörper 6 um ein Kunststoffpalett in der Art, wie es etwa aus der DE 10 2009 041 436 AI oder US 2007/0056483 AI bekannt geworden ist. Die hier allgemein als Vorsprünge bezeichneten Teile 13 stellen Standfüsse dar. Die Standfüsse 13 sind in drei sich in Längs- und Querrichtung erstreckenden Reihen angeordnet. Die Standfüsse 13 ermöglichen, dass eine (hier nicht dargestellte) Gabel beispielsweise eines Gabelstaplers oder Hubwagens unter dem Bodenabschnitt 14 einführbar ist und das Palett heben kann. Die Vorsprünge bzw. Stützfüsse 13 sind becherförmig ausgestaltet. Die Vorsprünge 13 schliessen an entsprechende Öffnungen im Bodenabschnitt 14 an. Derartige Kunststoffpalette lassen sich so einfach stapeln. FIG. 3 shows a perspective view of the support element 6 for the elevator car floor. The support member 6 has a flat bottom portion 14 and nine projections 13 formed thereon. This support element is designed as a one-piece molded body. Such a support structure can be made of different plastics, but preferably thermoplastics (eg PU, PP, PE). In the present exemplary embodiment according to FIG. 3, the support body 6 is a plastic pallet of the kind which has become known, for example, from DE 10 2009 041 436 A1 or US 2007/0056483 A1. The parts 13, here generally referred to as projections, constitute feet. The feet 13 are arranged in three rows extending in the longitudinal and transverse directions. The feet 13 allow a fork (not shown) of, for example, a forklift or lift truck to be inserted under the floor section 14 and lift the pallet. The projections or Support legs 13 are cup-shaped. The projections 13 connect to corresponding openings in the bottom portion 14. Such plastic pallets can be stacked so easily.
Kunststoffpalette lassen sich beispielsweise in einem Spritzgiessverfahren oder durch Warmumformen auf einfache Art und Weise herstellen. Palette sind in verschiedenen, standardisierten Grössen im Handel kostengünstig erhältlich. Für kleinere Aufzugskabinen könnten die Palette mittels Schneid- oder anderen Bearbeitungsverfahren verkleinert werden. Ein derart verkleinerter Stützkörper 6 ist in Figur 4 gezeigt, der aus dem Palett aus Figur 3 hervorgegangen ist. Plastic pallets can be produced, for example, in an injection molding process or by hot forming in a simple manner. Pallets are available inexpensively in various standardized sizes commercially. For smaller elevator cars, the pallet could be downsized by means of cutting or other machining methods. Such a reduced support body 6 is shown in Figure 4, which has emerged from the pallet of Figure 3.
Grundsätzlich könnten auch andere Palette bzw. Ladungsträger als Stützstruktur für den Kabinenboden einer Aufzugskabine verwendet werden. Beispielsweise könnte auch ein unter der Bezeichnung "Europalett" bekanntes Holzpalett in einem Kabinenboden integriert werden (Fig. 5). Das klassische Holzpalett weist anstatt einzelner Standfüsse drei in Längsrichtung verlaufende Kufen 15 auf. Die Kufen 15 werden durch Holzbretter gebildet, die über Abstandselemente mit den ebenfalls durch Holzbretter gebildeten Bodenabschnitt 14 verbunden sind. Kufen aufweisende Palette können - wie die Figuren 6 und 7 zeigen - aber auch als Kunststoffpalette ausgestaltet sein. Ein derartiges Kunststoffpalett ist beispielsweise aus der US 2003/0110990 AI bekannt geworden. In Figur 7 ist mit strichlierten Linien die Grundstruktur eines Kabinenbodens angedeutet, in der das Kunststoffpalett 6 eingefasst ist. In principle, other pallet or load carrier could be used as a support structure for the cabin floor of an elevator car. For example, a wooden pallet known by the name "Europalett" could also be integrated in a cabin floor (FIG. 5). The classic wooden pallet has instead of individual feet three running in the longitudinal direction runners 15. The skids 15 are formed by wooden boards, which are connected by spacers with the also formed by wooden boards bottom portion 14. Runners having pallet can - as the figures 6 and 7 show - but also be designed as a plastic pallet. Such a plastic pallet has become known, for example, from US 2003/0110990 AI. In Figure 7, the basic structure of a cabin floor is indicated by dashed lines, in which the plastic pallet 6 is enclosed.
In Figur 8 ist ein weiteres Beispiel für einen Boden 5 einer Aufzugskabine 3 dargestellt. Für die Stützstruktur wird ebenfalls ein Kunststoffpalett 5 verwendet, das mehrere Standfüsse 13 aufweist. Das Stützelement 6 ist in einer Grundstruktur mit in Längs- und Querrichtung verlaufenden Trägern 18 und 19 angeordnet. Für einen stabilen und steifen Boden sind die jeweils drei Quer- und Längsträger 18, 19 derart positioniert, dass sich die Standfüsse 13 auf den Trägern 18, 19 abstützen. Wie inbesondere aus der vergrösserten Detailansicht in Figur 8 hervorgeht, können die Querträger 18 als U-förmige Profilschienen 17 ausgebildet sein. FIG. 8 shows a further example of a floor 5 of an elevator car 3. For the support structure, a plastic pallet 5 is also used, which has a plurality of feet 13. The support element 6 is arranged in a basic structure with longitudinally and transversely extending supports 18 and 19. For a stable and rigid floor, the three transverse and longitudinal beams 18, 19 are positioned such that the feet 13 are supported on the beams 18, 19. As can be seen in particular from the enlarged detailed view in FIG. 8, the cross members 18 can be designed as U-shaped profiled rails 17.
Weiter kann es vorteilhaft sein, entsprechende Mittel oder Einrichtungen zur lagemässi- gen Fixierung der Stützstruktur zu verwenden. Die Figuren 9 und 10 zeigen beispielhaft, wie die Stützelemente lagemässig im Boden fixiert werden können. Je eine Längsreihe von Standfüssen 13 ist in jeweils einer Profilschiene 17 aufgenommen. Die drei Profilschienen 17 ihrerseits können mit den Querträgern beispielsweise durch eine Schweissverbindung oder unter Verwendung anderer Befestigungsmittel verbunden sein. Die jeweiligen Querträger 19 sind in Figur 9 durch strichlierte Linien angedeutet. Die Profilschiene (bzw. Längsträger) 17 (bzw. 18) und die Querträger 19 können beispielsweise aus Stahl gefertigt sein. Furthermore, it can be advantageous to use corresponding means or devices for the positional fixing of the support structure. FIGS. 9 and 10 show by way of example, how the support elements can be fixed in position in the ground. Depending on a longitudinal row of feet 13 is received in each case a rail 17. The three rails 17 in turn can be connected to the cross members, for example, by a welded connection or using other fasteners. The respective cross member 19 are indicated in Figure 9 by dashed lines. The rail (or side member) 17 (or 18) and the cross member 19 may be made for example of steel.
In Figur 11 ist eine weitere Variante für ein Kunststoffpalett gezeigt. Dieses Palett unterscheidet sich vom vorhergehenden Ausführungsbeispiel im Wesentlichen lediglich dadurch, dass der Bodenabschnitt 14 speziell geformte Unterbrüche aufweist, die eine Wabenstruktur bilden. Selbstverständlich wären aber auch andere Ausgestaltungen denkbar. So könnten die Unterbrüche in der Draufsicht zum Beispiel rechteckig ausgestaltet sein. Dank den Unterbrechungen kann das Gewicht nochmals reduziert werden. FIG. 11 shows a further variant for a plastic pallet. This pallet differs from the previous embodiment substantially only in that the bottom portion 14 has specially shaped interruptions forming a honeycomb structure. Of course, other embodiments would be conceivable. Thus, the interruptions in the plan view could be configured, for example, rectangular. Thanks to the interruptions, the weight can be further reduced.
Figur 12 zeigt ein Beispiel, wie das Kunststoffpalett 6 aus Figur 11 in einem Kabinenboden verbaut sein könnte. Die Grundstruktur des Kabinenbodens 5 verfügt über eine als Platte ausgestaltete Unterseite 8, in welcher Führungsnuten zur Aufnahme der Standfüsse 13 angeordnet sind. Wie Figur 12 weiterhin deutlich zeigt, weisen die Standfüsse konisch verlaufende Stützwandabschnitte 22 auf. Die becherförmigen Standfüsse 13 sind durch einen planparallel zur Standfläche verlaufenden Stützbodenabschnitt 21 verschlossen. Auf der gegenüberliegenden Seite befindet sich eine Deckplatte 20. Das Stützelement 6 ist somit allseitig von der Grundstruktur umgeben. Für ein optisch vorteilhaftes Erscheinungsbild wird über die vorzugsweise metallische Deckplatte eine Bodenplatte 7 gelegt, die schliesslich die Standfläche vorgibt. Diese Bodenplatte 7 kann aus unterschiedlichsten Materialien, wie etwa Marmor, einem Laminat oder Kunststoff bestehen. FIG. 12 shows an example of how the plastic pallet 6 from FIG. 11 could be installed in a cabin floor. The basic structure of the cabin floor 5 has an underside 8 configured as a plate, in which guide grooves for receiving the feet 13 are arranged. As FIG. 12 furthermore clearly shows, the feet have conically extending support wall sections 22. The cup-shaped feet 13 are closed by a plane parallel to the base extending support bottom portion 21. On the opposite side there is a cover plate 20. The support member 6 is thus surrounded on all sides by the basic structure. For a visually advantageous appearance, a bottom plate 7 is laid over the preferably metallic cover plate, which finally determines the footprint. This bottom plate 7 may be made of a variety of materials, such as marble, a laminate or plastic.
