Definitions
- the invention relates to a car for an elevator in an elevator shaft according to the preamble of claim 1.
- the dimensions of elevator systems with cars suspended from suspension elements are significantly influenced by the types of suspension element arrangement.
- a disadvantage of known devices is, in particular, that deflection rollers arranged outside of the elevator car necessitate a large shaft headroom, a large shaft width and/or a deeper shaft pit.
- the deflection rollers require space below or above the car.
- the EP 1 566 358 A1 describes a machine-room-less traction sheave elevator in which all components of the drive or the control, which are arranged above or below the track of the car in known machine-room-less elevator concepts, are relocated next to the track of the car.
- the car is expediently designed as a self-supporting car without a separate safety frame and with safety gears and cable pulleys integrated into the car floor.
- the deflection rollers are integrated in the floor or in the ceiling of the elevator car between two metal sheets.
- the cabin floor or the cabin ceiling with the integrated deflection rollers can be implemented in a stiff, load-bearing sandwich construction.
- the suspension and propulsion means can be guided in an inner floor duct or a ceiling duct.
- EP1970341 A1 which is also relevant prior art, discloses the preamble of claim 1.
- a shaft pit with a depth of 200mm can be realized.
- the floor slab of the building must have a recess in the area of the elevator shaft, since the floor structure of a building is normally no higher than 150mm.
- the necessary deepening in the building floor slab represents a high amount of work when constructing a building and is in some cases not feasible, e.g. when retrofitting an elevator in an existing building.
- EP 1 818 303 A1 described that in the course of each suspension element substrand on the cabin side, one or more additional own and spatially separate deflection rollers with separate axes are arranged immediately following the deflection roller within the cabin.
- the two deflection pulleys are arranged on an inside of the elevator car.
- the suspension element strands run through openings in the roof of the elevator car to the respective deflection rollers and from there back up to the machine carrier.
- the pulleys are entirely in the cabin and therefore take up a lot of space in the passenger area, the cover to be provided in addition to the other cabin equipment hangs far into the cabin.
- It is also an elevator with backpack suspension (pulleys arranged on one side of the cabin).
- the support structure in particular the floor height, must be made significantly more stable and therefore larger than is the case with a central suspension due to the greater forces, since the center of mass is at a distance from the suspension point.
- the efficiency of such an elevator system is significantly lower than that of an elevator with central suspension due to the greater forces between the guides and the guide rail.
- the object of the invention is to design a car for a preferably machine-room-less elevator in such a way that the largest possible part of the available shaft cross-section can be made available to the passenger and that the required shaft pit depth is reduced to a minimum and/or as small as possible shaft head height is required.
- the car width should be as large as possible with the same shaft width.
- the invention is implemented by a car for an elevator in an elevator shaft, which is suspended largely in its center of mass, ie centrally, at least in a ratio of 2:1.
- the car is guided by car guides.
- the car itself has a car floor, a car roof, car walls and an accessible passenger compartment in between.
- at least a first part of a deflection roller is located in an area between the car floor and the car roof, and a second part of this deflection roller is located in the car floor.
- the term "in the car floor” means the arrangement of at least one deflection roller in which, viewed spatially, the circumference of a deflection roller partially engages in a recess in the car floor, with the recess being provided in a central region of the car floor.
- the support means can be guided in the area of the elevator car floor.
- the support means are guided below the car floor or in the car floor by means of deflection rollers.
- the height of the car floor can be reduced to the minimum necessary for its stability and at the same time the suspension means can be laid under or in the floor.
- the height gained with the flat car floor can be saved in the shaft pit depth.
- the headroom is minimal, since no deflection rollers are required above the car.
- the car floor can be even smaller than in the first variant, since the suspension means no longer have to be accommodated in the floor area.
- the necessary shaft pit can be reduced to about 125mm.
- the deflection rollers integrated in the car ceiling and in the car roof build up only little or not at all over the car. This has a favorable effect on the required headroom height.
- the cable length required for this variant is less than for suspension elements guided in the area of the elevator car floor.
- a deflection pulley consists of the first part and the second part, with the first part between the car floor and the car roof and the second part is arranged within a horizontal projection of the vertical extension of the car floor.
- the deflection pulley is completely integrated into the elevator car, at least in the vertical direction. In this configuration, therefore, no part of the deflection pulley extends vertically downwards over the car floor. This leads to a particularly space-saving design of the elevator car. The necessary shaft pit can be further reduced. The same applies to the space requirement above the car when the deflection rollers are arranged in the area of the car roof.
- an axis of rotation of the deflection roller is arranged within a horizontal projection of the vertical extension of the car floor.
- the term "axis of rotation” is understood to mean a geometric axis of the deflection roller.
- the projection of the deflection roller into the area between the car floor and the car roof does not have a negative effect on the passenger, since a cover or specially shaped car walls separate the accessible passenger area from the deflection roller.
- the separation is formed by installations located in the passenger compartment or covers are provided in edge areas that are not entered anyway.
- a preferred embodiment of the invention provides that the deflection roller is formed by car walls shaped towards the passenger compartment.
- the car walls are preferably designed slightly inwardly shaped in the foot or ceiling area, so that there are no restrictions whatsoever in the middle height of the passenger compartment.
- the available width at the middle height of the passenger compartment is more important for well-being than the foot or ceiling area.
- a further embodiment provides that the cover of the deflection rollers to the interior of the passenger compartment is formed by at least one skirting board.
- a baseboard is anyway usually present and therefore does not impair the area perceived by the passenger.
- the deflection roller can be accommodated in or behind a control column. Controls are required for the passenger anyway, with the control column being one way of providing them.
- deflection rollers to the passenger compartment have covers that can be removed, simple maintenance and inspection of the deflection rollers and the suspension means can be carried out from inside the passenger compartment.
- This has the advantage that the fitter does not have to go into the pit or onto the car roof, which represent a larger danger area than the passenger compartment in the car.
- the car guides are at least partially attached to a car wall with fastening elements and are covered by a cover towards the interior of the passenger compartment, so that they are invisible to the passenger.
- the support means are guided around the bottom of the car floor, it is advantageous if the height of the car floor in the area of the support means is designed to be lower than the surrounding area of the car floor. Due to the fact that the elevator car floor is made thinner in the area of the elevator ropes, the support means can be guided around the elevator car there without additional space being required under the elevator car floor. The rest of the floor area is thicker and more stable. The floor thickness is adapted to the load.
- the height of the car floor can also be tapered in the areas of the car buffers.
- Buffers have a height specified by the manufacturer and a load-related deflection. By reducing the floor height in the area of the buffers, the buffers are only given as much height as they actually need them for their deflection, which also reduces the pit depth required for the car.
- the car floor In order to achieve the shaft pit depth defined in the task, the car floor must be extremely thin, which means that its load-bearing capacity with conventional construction is not sufficient for the intended load. Therefore, one embodiment provides that the floor is at least partially reinforced by metal or plastic foams.
- the deflection roller diameter In order not to unnecessarily narrow the passenger area with the cover or to preserve the appearance in the passenger area, it makes sense to limit the deflection roller diameter to less than 200mm.
- a smaller diameter of the deflection pulleys e.g. 80mm, can be implemented.
- the car is designed to be self-supporting without a car frame, since the car frame would take up additional space below, above and/or next to the car.
- the support means run in the area of the car floor, then the support means can be guided past the side of the car or, in a special embodiment, at least partially in an area inside the car wall.
- the area between an existing panel inner side and a panel rear edge is well suited for this. As a result, no space is required for the suspension equipment on the side next to the car. This reduces the required shaft width by at least 50mm.
- a particularly space-saving design is achieved by the deflection rollers in the area between the car floor and Car roof are arranged so close to the passenger area that they are within a cuboid car area between car floor and car roof, the cuboid outer edges are congruent with the outermost edges of the car floor. As a result, the deflection rollers build up very little or not at all on the side next to the car.
- a similar space-saving design is achieved by arranging the deflection rollers in the area between the car floor and car roof so close to the passenger area that they lie within a cuboid car area between the car floor and car roof, the cuboid outer surfaces of which are congruent with the largest formations of the car inner walls. This also means that the deflection rollers only build up very little on the side next to the car.
- the largest formation is determined by projecting an imaginary center plane in the center of the car perpendicular to the car floor and approximately parallel to an outer edge of the car floor into the car. Starting from this center plane, the most distant point that can be projected perpendicularly onto the car wall is determined for each car interior. The outer surfaces of the cuboid lie parallel to the central plane and in the determined point.
- At least a first part of a deflection roller is located in an area between the car floor and car roof, and a second part of this deflection roller is located in the car roof or at the same height as the car roof.
- cabin roof means the arrangement of at least one deflection roller in which, viewed spatially, the circumference of a deflection roller partially engages in a recess in the car roof, with the recess being provided in a central region of the car roof.
- the support means can be guided in the area of the suspended car ceiling.
- the support means are guided below the car roof in a suspended ceiling.
- the passenger compartment is not restricted at all, since there is often a suspended ceiling for accommodating lighting elements.
- the suspended ceiling does not have to be larger than it is anyway for the lighting elements and the deflection pulleys do not protrude above the car.
- a first embodiment is in the 1 and 6 shown. They show a car for an elevator, which is suspended in its center of mass in a ratio of 2:1 by means of suspension elements 10 guided over deflection rollers 6 .
- figure 5 shows this car in an elevator shaft 18 with the associated detail E in 9 .
- the top view shows how the car is guided by car guides 17 in guide rails 11 which are fastened to the elevator shaft 18 by means of rail brackets 12 .
- the counterweight 19 is still located in the elevator shaft 18 and is guided in counterweight guide rails 20 which are fastened to the elevator shaft 18 by means of counterweight rail brackets 21 .
- the counterweight 19 is suspended from the support means by means of a counterweight deflection roller 24 .
- the car has a car floor 1 and a car roof 4, under which a suspended car ceiling 5 is provided.
- a suspended car ceiling 5 In the suspended car ceiling 5 there is, for example, a car interior light (not shown).
- the walk-in passenger compartment 2 is bounded by car walls 13, a corrugated cover 7 and a double-leaf car door 16. It can be entered through the car door 16 arranged above a car door sill 15 .
- the car walls 13 consist of a plurality of panels connected to one another via rear edges.
- the support means 10 used here as flat belts run around the two deflection rollers 6 below the car floor 1 and along the side of the car walls 13 upwards into the shaft head.
- the support means 10 run on one side to the drive and from there to the counterweight deflection roller 24 and from there back up in the direction of the shaft head.
- one of the two deflection rollers 6 is arranged so close to the center of the car that its support means 10 can be guided upwards in the car wall 13 . 9 reveals this detail.
- the deflection roller 6 is proportionally integrated both in the car floor 1 and in the area between the car floor 1 and the car roof 4. So that the deflection roller does not interfere in the passenger compartment 2, it is connected by a wave-shaped, from the car floor 1 covered up to the car roof reaching cover 7.
- the second deflection roller 6 on the opposite side of the car is arranged at the same height, but to the side of the car floor 1. This variant is selected if the car wall 13 is to be straight on this side and the elevator shaft 18 offers enough space on the side for the deflection roller 6 .
- the special arrangement and selection of the necessary components make it possible to reduce the necessary space under the standing area for the passenger to a minimum and to realize a shaft pit depth of 150mm.
- the necessary shaft width is significantly smaller than in previously known solutions. So that the advantages of the compact design can be exploited to the full, the elevator car is preferably intended for elevators without a machine room.
- In 2 is the variant after the 1 , 5 and 9 modified by the car floor 1 overall thinner and is designed without a recess for the support means 10.
- the support means run below the floor.
- Deflection rollers 6 are both moved so far towards the middle of the car that the width of the shaft can be even smaller. Both deflection rollers 6 are covered by baseboards 14 .
- the car buffers 9 are arranged laterally in such a way that they partially protrude over the car floor 1 . As a result, long car buffers 9 can also be used.
- the very thin car floor 1 consists, among other things, of two plates, the space between which is filled with aluminum foam for reinforcement.
- the embodiment in 3 differs from the previous ones in that the support means 10 are not guided under the car floor 1 but in the car floor 1 in a channel from one car side to the other.
- the deflection rollers 6 are arranged in such a way that the support means 10 run underneath the car roof 4 .
- the deflection rollers 6 protrude here only so far into the area between the car roof 4 and the car floor 1 that they can still be accommodated within the suspended car ceiling 5 .
- the deflection rollers 6 used here have a diameter of 80mm. They can thus be completely accommodated in the 50 mm thick car roof 4 and the suspended car ceiling 5, which is also 50 mm thick.
- the required shaft head is only determined by the components in the shaft head that are independent of the car and by the car height and not by the deflection rollers 6. This special arrangement of the deflection rollers 6 makes it possible to reduce the necessary space above the car 4 to a minimum.
- the cover 7 of the passenger compartment 2 is curved in an oval shape in such a way that at least the part of the deflection roller 6 protruding into the area between the car roof 4 and the car floor 1 is covered by the cover 7 and is therefore not noticeable to the passenger.
- the oval shape of the passenger compartment 2 can preferably only be done on the side below or above where the deflection rollers 6 reach into the passenger compartment 2 .
- an operating column 8 necessary within the passenger compartment 2 is used to serve as a cover 7 for the part of the deflection roller 6 protruding into the passenger compartment 2 .
- the part of the deflection roller 6 that protrudes into the passenger compartment 2 is covered by a skirting board 14 .
- FIG. 12 shows a section through an elevator shaft 18 with a car in which the deflection rollers 6 are arranged according to the prior art in the car floor 1 and thus makes it clear that the necessary shaft pit depth is greater than 150mm is.
- the floor slab 26 of the building is perforated for the elevator shaft 18.
- FIG. 13 shows a section through an elevator shaft 18 with an elevator car, in which the deflection rollers 6 are arranged partly in the elevator car floor 1 and to a second part above the elevator car floor 1 . It can be seen that the invention manages with a pit depth of 150mm.
- the floor slab 26 of the building does not need to be broken as the floor structure 27 of the building is 150mm high.

Description
Die Erfindung betrifft einen Fahrkorb für einen Aufzug in einem Aufzugsschacht nach dem Oberbegriff des Anspruches 1.The invention relates to a car for an elevator in an elevator shaft according to the preamble of
Die Abmessungen von Aufzugsanlagen mit an Tragmitteln gehangenen Fahrkörben werden ganz wesentlich durch die Arten der Tragmittelanordnung beeinflusst. Ein Nachteil bekannter Einrichtungen liegt insbesondere darin, dass außerhalb des Aufzugsfahrkorbes angeordnete Umlenkrollen eine große Schachtkopfhöhe, eine große Schachtbreite und/oder eine tiefere Schachtgrube notwendig machen. Bei einem mindestens im Verhältnis 2:1 gehangenen Fahrkorb mit einer Tragmittelführung unter bzw. über dem Fahrkorb verlangen die Umlenkrollen Raum unter bzw. über dem Fahrkorb.The dimensions of elevator systems with cars suspended from suspension elements are significantly influenced by the types of suspension element arrangement. A disadvantage of known devices is, in particular, that deflection rollers arranged outside of the elevator car necessitate a large shaft headroom, a large shaft width and/or a deeper shaft pit. In the case of a car suspended in a ratio of at least 2:1 with a suspension element guide below or above the car, the deflection rollers require space below or above the car.
Die
Die Integration der Seilrollen in den Fahrkorbboden wird insbesondere in
Ähnliche Lösungen sind in
Die Nachteile der Lösungen mit in den Kabinenboden integrierten Umlenkrollen werden darin gesehen, dass die Höhe des Fahrkorbbodens durch die enthaltenen Rollen und Tragmittel bestimmt wird. Der Freiraum für die Umlenkrollen im Fahrkorboden muss mindestens so hoch sein, wie die Umlenkrollen, der Boden ist daher höher auszuführen, als die Umlenkrollen. Bei Verwendung von flachen Riemen als Tragmittel sind Umlenkrollen mit einem Mindestdurchmesser von 80mm möglich. Der Boden ist dann wenigstens 100mm hoch.The disadvantages of the solutions with deflection rollers integrated into the car floor are seen in the fact that the height of the car floor is determined by the rollers and suspension means contained. The clearance for the deflection rollers in the car floor must be at least as high as the deflection rollers, so the floor must be higher than the deflection rollers. When using flat belts as suspension means, deflection pulleys with a minimum diameter of 80mm are possible. The floor is then at least 100mm high.
Bei einer standardmäßigen Anordnung des Fahrkorbpuffers unterhalb des Kabinenbodens und unter Verzicht eines zusätzlichen Tragrahmens lässt sich damit eine Schachtgrube mit einer Tiefe von 200mm realisieren. Bei einer Schachtgrube von 200mm muss die Gebäudebodenplatte im Bereich des Aufzugsschachtes eine Vertiefung aufweisen, da der Fußbodenaufbau eines Gebäudes normalerweise nicht größer als 150mm hoch ist. Die notwendige Vertiefung in der Gebäudebodenplatte stellt bei der Errichtung eines Gebäudes einen hohen Arbeitsaufwand dar und ist in einigen Fällen nicht realisierbar, z.B. bei der Nachrüstung eines Aufzuges in ein bestehendes Gebäude.With a standard arrangement of the car buffer below the car floor and without an additional support frame, a shaft pit with a depth of 200mm can be realized. With a shaft pit of 200mm, the floor slab of the building must have a recess in the area of the elevator shaft, since the floor structure of a building is normally no higher than 150mm. The necessary deepening in the building floor slab represents a high amount of work when constructing a building and is in some cases not feasible, e.g. when retrofitting an elevator in an existing building.
Als eine spezielle Ausgestaltung ist in
In dieser Anmeldung sind die Umlenkrollen vollständig in der Kabine und nehmen daher viel Platz im Fahrgastbereich ein, die zusätzlich zur sonstigen Kabinenausstattung vorzusehende Abdeckung hängt weit in die Kabine hinein. Weiterhin handelt es sich um einen Aufzug in Rucksackaufhängung (an einer Seite der Kabine angeordnete Umlenkrollen). Bei einer einseitigen Aufhängung muss die Tragstruktur, insbesondere die Bodenhöhe aufgrund der größeren Kräfte deutlich stabiler und damit größer ausgeführt werden, als dies bei einer zentralen Aufhängung der Fall ist, da der Massenschwerpunkt vom Aufhängungspunkt einen Abstand hat. Der Wirkungsgrad einer solchen Aufzugsanlage ist durch die größeren Kräfte zwischen den Führungen und der Führungsschiene deutlich geringer, als bei einem Aufzug mit zentraler Aufhängung.In this application, the pulleys are entirely in the cabin and therefore take up a lot of space in the passenger area, the cover to be provided in addition to the other cabin equipment hangs far into the cabin. It is also an elevator with backpack suspension (pulleys arranged on one side of the cabin). In the case of a one-sided suspension, the support structure, in particular the floor height, must be made significantly more stable and therefore larger than is the case with a central suspension due to the greater forces, since the center of mass is at a distance from the suspension point. The efficiency of such an elevator system is significantly lower than that of an elevator with central suspension due to the greater forces between the guides and the guide rail.
Aufgabe der Erfindung ist es, einen Fahrkorb für einen vorzugsweise triebwerksraumlosen Aufzug so auszubilden, dass ein größtmöglicher Teil des zur Verfügung stehenden Schachtquerschnittes dem Fahrgast zur Verfügung gestellt werden kann und dass eine Reduzierung der erforderlichen Schachtgrubentiefe auf ein Minimum erreicht wird und/oder eine möglichst kleine Schachtkopfhöhe erforderlich wird. Die Fahrkorbbreite, soll bei gleicher Schachtbreite möglichst groß sein.The object of the invention is to design a car for a preferably machine-room-less elevator in such a way that the largest possible part of the available shaft cross-section can be made available to the passenger and that the required shaft pit depth is reduced to a minimum and/or as small as possible shaft head height is required. The car width should be as large as possible with the same shaft width.
Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruches 1 gelöst. Ausgestaltende Merkmale sind in den Unteransprüchen angegeben.According to the invention, the object is achieved by the features of
Die Erfindung wird durch einen Fahrkorb für einen Aufzug in einem Aufzugsschacht realisiert, der mindestens im Verhältnis 2:1 weitestgehend in seinem Massenschwerpunkt, also zentral, gehangen ist. Der Fahrkorb wird durch Fahrkorbführungen geführt. Der Fahrkorb selbst besitzt einen Fahrkorbboden, ein Fahrkorbdach, Fahrkorbwände und dazwischen einen betretbaren Fahrgastraum. Erfindungsgemäß befindet sich mindestens ein erster Teil einer Umlenkrolle in einem Bereich zwischen Fahrkorbboden und Fahrkorbdach und ein zweiter Teil dieser Umlenkrolle im Fahrkorbboden.The invention is implemented by a car for an elevator in an elevator shaft, which is suspended largely in its center of mass, ie centrally, at least in a ratio of 2:1. The car is guided by car guides. The car itself has a car floor, a car roof, car walls and an accessible passenger compartment in between. According to the invention, at least a first part of a deflection roller is located in an area between the car floor and the car roof, and a second part of this deflection roller is located in the car floor.
Mit dem Begriff "im Fahrkorbboden" wird die Anordnung von mindestens einer Umlenkrolle verstanden, bei der räumlich gesehen der Umfang einer Umlenkrolle teilweise in eine Ausnehmung des Fahrkorbbodens eingreift, wobei die Ausnehmung jeweils in einem mittleren Bereich des Fahrkorbbodens vorgesehen ist.The term "in the car floor" means the arrangement of at least one deflection roller in which, viewed spatially, the circumference of a deflection roller partially engages in a recess in the car floor, with the recess being provided in a central region of the car floor.
Mit der Erfindung ist eine Führung der Tragmittel im Bereich des Fahrkorbbodens realisierbar. Die Tragmittel werden dabei unterhalb des Fahrkorbbodens oder im Fahrkorbboden mittels Umlenkrollen geführt.With the invention, the support means can be guided in the area of the elevator car floor. The support means are guided below the car floor or in the car floor by means of deflection rollers.
Durch das Hineinreichen der im Bereich des Fahrkorbbodens angeordneten Umlenkrollen in den Bereich zwischen Fahrkorbboden und Fahrkorbdach kann die Höhe des Fahrkorbbodens auf ein für dessen Stabilität notwendiges Mindestmaß reduziert werden und gleichzeitig die Tragmittel unter oder im Boden verlegt werden. Die mit dem flachen Fahrkorbboden gewonnene Höhe kann in der Schachtgrubentiefe eingespart werden. Gleichzeitig ist der Schachtkopf minimal, da oberhalb des Fahrkorbes keine Umlenkrollen benötigt werden.By extending the deflection rollers arranged in the area of the car floor into the area between the car floor and car roof, the height of the car floor can be reduced to the minimum necessary for its stability and at the same time the suspension means can be laid under or in the floor. The height gained with the flat car floor can be saved in the shaft pit depth. At the same time, the headroom is minimal, since no deflection rollers are required above the car.
Durch das Hineinreichen der im oberen Bereich des Fahrkorbes angeordneten Umlenkrollen in den Bereich zwischen Fahrkorbboden und Fahrkorbdach kann der Fahrkorbboden noch geringer ausfallen, als bei der ersten Variante, da die Tragmittel nun nicht mehr im Bodenbereich untergebracht werden müssen. Die notwendige Schachtgrube kann dabei auf etwa 125mm reduziert werden. Die in der Fahrkorbdecke und im Fahrkorbdach integrierten Umlenkrollen bauen nur noch wenig oder gar nicht über dem Fahrkorb auf. Dies wirkt sich günstig auf die erforderliche Schachtkopfhöhe aus. Gleichzeitig ist die benötigte Seillänge bei dieser Variante geringer, als bei im Bereich des Fahrkorbbodens geführten Tragmitteln.Due to the fact that the deflection rollers arranged in the upper area of the car reach into the area between the car floor and the car roof, the car floor can be even smaller than in the first variant, since the suspension means no longer have to be accommodated in the floor area. The necessary shaft pit can be reduced to about 125mm. The deflection rollers integrated in the car ceiling and in the car roof build up only little or not at all over the car. This has a favorable effect on the required headroom height. At the same time, the cable length required for this variant is less than for suspension elements guided in the area of the elevator car floor.
In einer besonders bevorzugten Ausführung besteht eine Umlenkrolle aus dem ersten Teil und dem zweiten Teil, wobei der erste Teil zwischen dem Fahrkorbboden und dem Fahrkorbdach angeordnet ist und der zweite Teil innerhalb einer horizontalen Projektion der vertikalen Erstreckung des Fahrkorbbodens angeordnet ist. Die Umlenkrolle ist bei einer solchen Ausgestaltung zumindest in vertikaler Richtung komplett in den Fahrkorb integriert. Bei dieser Ausgestaltung steht also kein Teil der Umlenkrolle vertikal nach unten über den Fahrkorbboden. Dies führt zu einer besonders platzsparenden Bauweise des Fahrkorbs. Die notwendige Schachtgrube kann dabei weiter reduziert werden. Entsprechendes gilt für den Platzbedarf oberhalb des Fahrkorbs bei einer Anordnung der Umlenkrollen im Bereich des Fahrkorbdachs.In a particularly preferred embodiment, a deflection pulley consists of the first part and the second part, with the first part between the car floor and the car roof and the second part is arranged within a horizontal projection of the vertical extension of the car floor. In such an embodiment, the deflection pulley is completely integrated into the elevator car, at least in the vertical direction. In this configuration, therefore, no part of the deflection pulley extends vertically downwards over the car floor. This leads to a particularly space-saving design of the elevator car. The necessary shaft pit can be further reduced. The same applies to the space requirement above the car when the deflection rollers are arranged in the area of the car roof.
In einer weiteren Ausführung ist eine Drehachse der Umlenkrolle innerhalb einer horizontalen Projektion der vertikalen Erstreckung des Fahrkorbbodens angeordnet. Unter dem Begriff "Drehachse" wird eine geometrische Achse der Umlenkrolle verstanden.In a further embodiment, an axis of rotation of the deflection roller is arranged within a horizontal projection of the vertical extension of the car floor. The term "axis of rotation" is understood to mean a geometric axis of the deflection roller.
Für den Fahrgast wirkt sich das Hineinragen der Umlenkrolle in den Bereich zwischen Fahrkorbboden und Fahrkorbdach nicht negativ aus, da eine Abdeckung oder speziell geformte Fahrkorbwände den betretbaren Fahrgastbereich von der Umlenkrolle abtrennt. Die Abtrennung wird durch im Fahrgastraum befindliche Einbauten gebildet oder es werden Abdeckungen in Randbereichen vorgesehen, die ohnehin nicht betreten werden.The projection of the deflection roller into the area between the car floor and the car roof does not have a negative effect on the passenger, since a cover or specially shaped car walls separate the accessible passenger area from the deflection roller. The separation is formed by installations located in the passenger compartment or covers are provided in edge areas that are not entered anyway.
Eine bevorzugte Ausführung der Erfindung sieht vor, dass die Umlenkrolle durch zum Fahrgastraum hin geformte Fahrkorbwände ausgebildet wird. Die Fahrkorbwände werden vorzugsweise im Fuß- oder Deckenbereich leicht nach innen geformt ausgeführt, so dass in der mittleren Höhe des Fahrgastraumes keinerlei Einschränkungen auftreten. Die zur Verfügung stehende Breite in mittlerer Höhe des Fahrgastraumes ist für das Wohlbefinden wichtiger, als der Fuß- oder Deckenbereich.A preferred embodiment of the invention provides that the deflection roller is formed by car walls shaped towards the passenger compartment. The car walls are preferably designed slightly inwardly shaped in the foot or ceiling area, so that there are no restrictions whatsoever in the middle height of the passenger compartment. The available width at the middle height of the passenger compartment is more important for well-being than the foot or ceiling area.
Eine weitere Ausführung sieht vor, dass die Abdeckung der Umlenkrollen zum Inneren des Fahrgastraumes durch mindestens eine Fußleiste gebildet wird. Eine Fußleiste ist ohnehin meistens vorhanden und stellt daher keine Beeinträchtigung des vom Fahrgast wahrgenommenen Aufenthaltsbereiches dar.A further embodiment provides that the cover of the deflection rollers to the interior of the passenger compartment is formed by at least one skirting board. A baseboard is anyway usually present and therefore does not impair the area perceived by the passenger.
In einer Ausführung kann die Umlenkrolle in bzw. hinter einer Bediensäule untergebracht werden. Bedienelemente werden für den Fahrgast ohnehin benötigt, wobei die Bediensäule eine Möglichkeit der Bereitstellung dieser darstellt.In one embodiment, the deflection roller can be accommodated in or behind a control column. Controls are required for the passenger anyway, with the control column being one way of providing them.
Wenn die Umlenkrollen zum Fahrgastraum hin Abdeckungen besitzen, die abnehmbar sind, kann darüber eine einfache Wartung und Inspektion der Umlenkrollen und der Tragmittel vom Inneren des Fahrgastraumes aus erfolgen. Dies hat den Vorteil, dass der Monteur nicht in die Schachtgrube oder auf das Fahrkorbdach gehen muss, die einen größeren Gefahrenbereich darstellen, als der Fahrgastraum im Fahrkorb.If the deflection rollers to the passenger compartment have covers that can be removed, simple maintenance and inspection of the deflection rollers and the suspension means can be carried out from inside the passenger compartment. This has the advantage that the fitter does not have to go into the pit or onto the car roof, which represent a larger danger area than the passenger compartment in the car.
Eine Möglichkeit sieht vor, dass die Fahrkorbführungen mit Befestigungselementen zumindest teilweise an einer Fahrkorbwand befestigt sind und durch eine Abdeckung zum Inneren des Fahrgastraumes hin abgedeckt werden, damit sie für den Fahrgast unsichtbar werden.One possibility provides that the car guides are at least partially attached to a car wall with fastening elements and are covered by a cover towards the interior of the passenger compartment, so that they are invisible to the passenger.
Werden die Tragmittel unten um den Fahrkorbboden herumgeführt, ist es vorteilhaft, wenn die Höhe des Fahrkorbbodens im Bereich der Tragmittel geringer ausgebildet wird, als der umgebende Bereich des Fahrkorbbodens. Dadurch, dass der Fahrkorbboden im Bereich der Aufzugsseile dünner ausgeführt wird, können dort die Tragmittel um den Fahrkorb geführt werden, ohne dass unter dem Fahrkorbboden zusätzlicher Raum benötigt wird. Der restliche Bodenbereich ist dicker und stabiler. Die Bodendicke wird der Belastung angepasst ausgeführt.If the support means are guided around the bottom of the car floor, it is advantageous if the height of the car floor in the area of the support means is designed to be lower than the surrounding area of the car floor. Due to the fact that the elevator car floor is made thinner in the area of the elevator ropes, the support means can be guided around the elevator car there without additional space being required under the elevator car floor. The rest of the floor area is thicker and more stable. The floor thickness is adapted to the load.
Bei am Fahrkorbboden befestigten Fahrkorbpuffern kann die Höhe des Fahrkorbbodens in den Bereichen der Fahrkorbpuffer ebenfalls verjüngt ausgebildet sein. Puffer haben eine vom Hersteller vorgegebene Höhe und eine belastungsbedingte Einfederung. Durch Verjüngung der Bodenhöhe im Bereich der Puffer wird den Puffern nur so viel Höhe zur Verfügung gestellt, sie diese tatsächlich für deren Einfederung brauchen, wodurch ebenfalls die für den Fahrkorb benötigte Schachtgrubentiefe reduziert wird.In the case of car buffers fastened to the car floor, the height of the car floor can also be tapered in the areas of the car buffers. Buffers have a height specified by the manufacturer and a load-related deflection. By reducing the floor height in the area of the buffers, the buffers are only given as much height as they actually need them for their deflection, which also reduces the pit depth required for the car.
Zum Erreichen der in der Aufgabenstellung definierten Schachtgrubentiefe muss der Fahrkorbboden extrem dünn sein, wodurch dessen Tragfähigkeit bei herkömmlicher Bauweise nicht für die vorgesehene Belastung ausreicht. Daher sieht eine Ausführung vor, dass der Boden mindestens partiell durch Metall- oder Kunststoffschäume verstärkt wird.In order to achieve the shaft pit depth defined in the task, the car floor must be extremely thin, which means that its load-bearing capacity with conventional construction is not sufficient for the intended load. Therefore, one embodiment provides that the floor is at least partially reinforced by metal or plastic foams.
Um den Fahrgastbereich durch die Abdeckung nicht unnötig zu schmälern bzw. um die Optik im Fahrgastbereich zu wahren, ist es sinnvoll, den Umlenkrollendurchmesser auf unter 200mm zu begrenzen. Durch die Wahl moderner Tragmittel aus dünnen, vorzugsweise kunststoffummantelten Seilen oder Flachriemen kann ein kleiner Durchmesser der Umlenkrollen, z.B. 80mm, realisiert werden.In order not to unnecessarily narrow the passenger area with the cover or to preserve the appearance in the passenger area, it makes sense to limit the deflection roller diameter to less than 200mm. By choosing modern suspension equipment made of thin, preferably plastic-coated ropes or flat belts, a smaller diameter of the deflection pulleys, e.g. 80mm, can be implemented.
Für die Realisierung der Aufgabenstellung ist es besonders von Vorteil, wenn der Fahrkorb ohne Fahrkorbrahmen selbsttragend ausgebildet ist, da der Fahrkorbrahmen zusätzlichen Platz unter, über und/oder neben dem Fahrkorb beanspruchen würde.For the realization of the task, it is particularly advantageous if the car is designed to be self-supporting without a car frame, since the car frame would take up additional space below, above and/or next to the car.
Verlaufen die Tragmittel im Bereich des Fahrkorbbodens, dann können die Tragmittel seitlich außen am Fahrkorb vorbei geführt werden oder in einer besonderen Ausgestaltung zumindest teilweise in einem Bereich innerhalb der Fahrkorbwand. Gut eignet sich dafür der Bereich zwischen einer vorhandenen Paneelinnenseite und einer Paneelrückkantung. Dadurch wird seitlich neben dem Fahrkorb kein Platz für die Tragmittel benötigt. Dies reduziert die notwendige Schachtbreite um mindestens 50mm.If the support means run in the area of the car floor, then the support means can be guided past the side of the car or, in a special embodiment, at least partially in an area inside the car wall. The area between an existing panel inner side and a panel rear edge is well suited for this. As a result, no space is required for the suspension equipment on the side next to the car. This reduces the required shaft width by at least 50mm.
Eine besonders platzsparende Ausführung wird erreicht, indem die Umlenkrollen in dem Bereich zwischen Fahrkorbboden und Fahrkorbdach derart nah zum Fahrgastbereich angeordnet werden, dass sie innerhalb eines quaderförmigen Fahrkorbbereiches zwischen Fahrkorbboden und Fahrkorbdach liegen, dessen Quaderaussenkanten mit den äußersten Außenkanten des Fahrkorbbodens deckungsgleich sind. Dadurch bauen die Umlenkrollen nur sehr wenig oder gar nicht seitlich neben dem Fahrkorb auf.A particularly space-saving design is achieved by the deflection rollers in the area between the car floor and Car roof are arranged so close to the passenger area that they are within a cuboid car area between car floor and car roof, the cuboid outer edges are congruent with the outermost edges of the car floor. As a result, the deflection rollers build up very little or not at all on the side next to the car.
Eine ähnlich platzsparende Ausführung wird erreicht, indem die Umlenkrollen in dem Bereich zwischen Fahrkorbboden und Fahrkorbdach derart nah zum Fahrgastbereich angeordnet werden, dass sie innerhalb eines quaderförmigen Fahrkorbbereiches zwischen Fahrkorbboden und Fahrkorbdach liegen, dessen Quaderaussenflächen mit den größten Ausformungen der Fahrkorbinnenwände deckungsgleich sind. Auch dadurch bauen die Umlenkrollen nur sehr wenig seitlich neben dem Fahrkorb auf.A similar space-saving design is achieved by arranging the deflection rollers in the area between the car floor and car roof so close to the passenger area that they lie within a cuboid car area between the car floor and car roof, the cuboid outer surfaces of which are congruent with the largest formations of the car inner walls. This also means that the deflection rollers only build up very little on the side next to the car.
Die größte Ausformung wird ermittelt, indem eine gedachte Mittelebene in der Mitte des Fahrkorbes senkrecht zum Fahrkorbboden und in etwa parallel zu einer Außenkante des Fahrkorbbodens in den Fahrkorb projiziert wird. Von dieser Mittelebene ausgehend wird zu jeder Fahrkorbinnenseite der am weitesten entfernteste senkrecht auf die Fahrkorbwand projizierbare Punkt ermittelt. Die Quaderaussenflächen liegen parallel zu der Mittelebene und in dem ermittelten Punkt.The largest formation is determined by projecting an imaginary center plane in the center of the car perpendicular to the car floor and approximately parallel to an outer edge of the car floor into the car. Starting from this center plane, the most distant point that can be projected perpendicularly onto the car wall is determined for each car interior. The outer surfaces of the cuboid lie parallel to the central plane and in the determined point.
In einer weiteren Ausgestaltung befindet sich mindestens ein erster Teil einer Umlenkrolle in einem Bereich zwischen Fahrkorbboden und Fahrkorbdach und ein zweiter Teil dieser Umlenkrolle im Fahrkorbdach oder in gleicher Höhe, wie das Fahrkorbdach.In a further embodiment, at least a first part of a deflection roller is located in an area between the car floor and car roof, and a second part of this deflection roller is located in the car roof or at the same height as the car roof.
Mit dem Begriff im "Fahrkorbdach" wird die Anordnung von mindestens einer Umlenkrolle verstanden, bei der räumlich gesehen der Umfang einer Umlenkrolle teilweise in eine Ausnehmung des Fahrkorbdachs eingreift, wobei die Ausnehmung jeweils in einem mittleren Bereich des Fahrkorbdachs vorgesehen ist.The term “cabin roof” means the arrangement of at least one deflection roller in which, viewed spatially, the circumference of a deflection roller partially engages in a recess in the car roof, with the recess being provided in a central region of the car roof.
In dieser weiteren Ausgestaltung ist eine Führung der Tragmittel im Bereich der abgehangenen Fahrkorbdecke realisierbar. Die Tragmittel werden dabei unterhalb des Fahrkorbdaches in einer abgehangenen Decke geführt.In this further embodiment, the support means can be guided in the area of the suspended car ceiling. The support means are guided below the car roof in a suspended ceiling.
Durch die Anordnung der Umlenkrollen in der abgehangenen Decke ist der Fahrgastraum gar nicht eingeschränkt, da oft eine abgehangene Decke zum Unterbringen von Beleuchtungselementen vorhanden ist. Bei der Verwendung von Umlenkrollen mit kleinem Durchmesser muss die abgehangene Decke nicht größer ausgeführt werden, als sie ohnehin für die Beleuchtungselemente ist und die Umlenkrollen ragen nicht oben über den Fahrkorb hinaus.Due to the arrangement of the deflection rollers in the suspended ceiling, the passenger compartment is not restricted at all, since there is often a suspended ceiling for accommodating lighting elements. When using deflection pulleys with a small diameter, the suspended ceiling does not have to be larger than it is anyway for the lighting elements and the deflection pulleys do not protrude above the car.

Der Fahrkorb besitzt einen Fahrkorbboden 1 und ein Fahrkorbdach 4, unter dem eine abgehangene Fahrkorbdecke 5 vorgesehen ist. In der abgehangenen Fahrkorbdecke 5 befindet sich beispielsweise eine nicht dargestellte Fahrkorbinnenbeleuchtung. Der begehbare Fahrgastraum 2 wird durch Fahrkorbwände 13, einer wellenförmigen Abdeckung 7 und durch eine zweiflügelige Fahrkorbtür 16 begrenzt. Durch die oberhalb einer Fahrkorbtürschwelle 15 angeordneten Fahrkorbtür 16 ist er betretbar.

Die Tragmittel 10 verlaufen auf einer Seite zum Antrieb und von dort aus zur Gegengewichtsumlenkrolle 24 und von dort aus wieder nach oben in Richtung Schachtkopf.The support means 10 used here as flat belts run around the two
Damit kein zusätzlicher Platz für die Umlenkrolle 6 auf der Gegengewichtsseite im Schachtquerschnitt erforderlich wird, ist eine der beiden Umlenkrollen 6 derart nah zur Fahrkorbmitte angeordnet, dass deren Tragmittel 10 in der Fahrkorbwand 13 nach oben geführt werden können.
Da dieser Fahrkorb für eine Schachtgrubentiefe von 150mm vorgesehen ist, wird die Umlenkrolle 6 anteilig sowohl im Fahrkorbboden 1 integriert als auch in dem Bereich zwischen Fahrkorbboden 1 und Fahrkorbdach 4. Damit die Umlenkrolle im Fahrgastraum 2 nicht stört, ist sie durch eine wellenförmige, vom Fahrkorbboden 1 bis zum Fahrkorbdach reichenden Abdeckung 7 abgedeckt.Since this car is intended for a pit depth of 150mm, the
