- EP 2219985 B1 describes an elevator system with two lift cabins which can be displaced in a vertical direction in a lift shaft, a self-contained carrying means guided around a lower deflection roller and an upper deflection roller, one of which
- the support means has a plurality of coupling elements, which may be embodied for example as holes or cams.
- a coupling device of an elevator car can be coupled to and decoupled from a coupling element, whereby a drive connection between the respective elevator car and the suspension element can be produced and released.
- An elevator car coupled to a suspension element can thus be displaced in the first elevator shaft by means of the suspension element drivable by the respective drive machine.
- the elevator cabins are only moved in one direction, ie only upwards or only downwards, in said elevator shaft.
- the elevator system has a further elevator shaft.
- the elevator cars can be moved horizontally between the two elevator shafts by means of a transfer device.
- Elevator system coupled to an elevator car at a lower or an upper end position via their coupling device and a coupling element to a support means and is displaced above the support means of the associated drive machine up or down until it has reached the upper or lower end position.
- the elevator car decoupled from the suspension element and is from a transfer device in the elevator shaft for the other direction of displacement horizontally in the other
- the elevator system according to the invention has a first elevator car and a second elevator car which can be displaced in a vertical direction in a first elevator shaft. It also has a self-contained to a lower
- the suspension element has a first and a second coupling element, to which a coupling device of an elevator car can couple and decouple, whereby a drive connection between the respective elevator car and the suspension element can be produced and released.
- the elevator car can thus be displaced in the first elevator shaft by means of the suspension element drivable by the respective drive machine.
- the two coupling elements of the suspension element are arranged such that when the first elevator car coupled to the suspension element via a coupling element is displaced from a lower end position to an upper end position or vice versa, no coupling element of the suspension element is guided around a deflection roller.
- the coupling elements can be optimally suited to their task, the coupling of the
- Coupling device en to a support means to allow to be designed.
- no space must be provided in the area of the deflection rollers, in which the coupling elements can be guided around the deflection rollers. This allows a simpler construction of the elevator system.
- the arrangement according to the invention of the coupling elements on a suspension means makes it possible to control the drive machine assigned to the suspension element in such a way that during the operation of the elevator system a coupling element is never guided around a deflection roller.
- the elevator shaft is arranged in or on a building and runs mainly in the vertical direction, so that the elevator cars in a shift in the
- Elevator shaft are shifted mainly vertically.
- the said first and second elevator cars do not have to be displaceable simultaneously in the first elevator shaft.
- the first elevator car is for this purpose in particular before or during the relocation of the second elevator car removed from the elevator shaft.
- the support means is self-contained, so for example designed annular. It can also be called endless. This does not necessarily mean that it exists as a homogeneous ring or just one piece.
- the support means is guided around a lower and an upper deflection roller, wherein at least one deflection roller as
- the deflection rollers have in particular an effective diameter of less than 100 mm. Such a small effective diameter of a pulley serving as a pulley allow a gearless drive of the support means, which takes up little installation space.
- the deflection rollers are in particular arranged so that their respective axis of rotation is perpendicular to an adjacent shaft wall of the elevator shaft.
- Tensioning device may be arranged, with which on the one hand the required
- Length changes of the support means are compensated.
- the required clamping forces can be generated for example with tension weights, gas springs or metal springs.
- the drive machine is designed in particular as an electric motor, which is controlled by an elevator control.
- the elevator control controls the complete operation of the elevator system, so it controls all controllable components of the elevator system and is connected to switches and sensors of the elevator system.
- Elevator control can be implemented as a single central elevator control or consist of several decentralized control, which are responsible for subtasks.
- the coupling devices arranged on the elevator cars are arranged in particular on a floor or a roof of the elevator cars and are controlled by the above-mentioned elevator control.
- the coupling to a coupling element of the support means is in particular a form-fitting manner, wherein also a frictional
- the coupling element has in particular a mainly horizontally oriented recess in the example in a
- a retractable and retractable bolt of the coupling device can dip.
- About the coupling device and the coupling element can thus a positive or frictional connection between the elevator car and the
- Supporting means are manufactured, so that during a displacement or movement of the propellant and the elevator car is displaced. This is a drive connection between the elevator car and the support means and thus ultimately between the elevator car and the support means associated drive machine produced and also solvable again.
- the coupling devices are controlled such that only one elevator car is coupled at least during the displacement of an elevator car to a (single) suspension element. From a (single) suspension means so only one (single) elevator car is always moved in the shaft.
- the two coupling elements of the support means are arranged so that in a displacement of coupled via a coupling element to the support means first elevator car from a lower end position to an upper end position or vice versa, no coupling element comes into contact with a pulley.
- no coupling element comes into contact with a pulley.
- the coupling element does not touch the pulleys. It can thus no damage to a pulley by a
- This arrangement of the coupling elements on a support means makes it possible to control the drive means associated with the drive machine so that during operation of the
- Elevator system never comes a coupling element in contact with a pulley.
- the suspension means can therefore always be stopped in time so that the Ankoppeletti never reach the pulleys or comply, for example, a certain minimum distance to the pulleys.
- the two coupling elements of the support means are arranged so that when the coupled via a coupling element to the support means first elevator car has reached the upper end position at a shift up, the other coupling element is positioned so that the second elevator car assigned Coupling of the arranged in the lower end position of the second elevator car can be coupled to the other coupling element.
- the other coupling element Upon a displacement of the first elevator car down, the other coupling element is accordingly positioned upon reaching the lower end position of the first elevator car so that the coupling device arranged in the upper end position second
- Elevator cabin can be coupled to the other coupling element.
- the second elevator car can be coupled to a coupling element at the other end position and thus prepare the displacement of the second elevator car.
- the uncoupling of the first elevator car and the coupling of the second elevator car can take place at least partially simultaneously, thus enabling effective operation of the elevator system.
- the drive machine is controlled by an elevator control.
- This is intended to reverse a direction of movement of the support means for the next displacement of an elevator car when an elevator car has reached the lower end position or the upper end position depending on the direction of displacement.
- the elevator control is thus intended to shift the elevator cars in the elevator shaft only in one direction, ie only from bottom to top or only from top to bottom.
- the elevator system has at least one further support means with two vertically spaced apart arranged coupling elements and another further support means associated
- the coupling elements are as in the already described Suspension means arranged.
- the suspension elements are in particular arranged parallel next to one another in the elevator shaft.
- the elevator control is in particular intended to actuate the two drive machines of the suspension elements independently of one another. This can be displaced in the elevator shaft with a second support means simultaneously with the first elevator car and independently of the first elevator car another elevator car.
- the elevator system can be operated particularly effectively and it can be transported many passengers in particular with different destination floors in the building.
- the elevator system has more than two, in particular four, such suspension elements. It is also conceivable that the elevator system has more than four such suspension means.
- the coupling devices may be able to couple to the coupling elements of the various suspension elements.
- the coupling devices are then arranged horizontally, in particular displaceable transversely to their direction of actuation. If an elevator car is to be coupled to a suspension element, then first the coupling device is moved transversely to its actuating direction so that it is correctly positioned with respect to the coupling element of the corresponding suspension element. Subsequently, in particular by extending the bolt of the coupling element, the coupling to the support means take place. It is also possible for this case that per support means a correspondingly positioned coupling device is provided on the elevator car.
- a coupling device at a fixed position ie a non-displaceable coupling device, can be sufficient per elevator car. This is an assignment of an elevator car to a
- a coupling element of each support means is designed as a connecting element, which connects two free ends of Tragstoff puzzle together.
- the coupling element can advantageously fulfill a dual function, namely on the one hand enable the coupling of an elevator car and on the other hand a closed support means.
- the coupling element fulfills in particular the function of a so-called belt lock or a cable connector. This can very easily, inexpensively and safely from an open, elongated support member through Connecting the two free ends with the coupling element a self-contained support means are made.
- the support means thus consists of two support means parts whose free ends are connected by means of a primary coupling element and a secondary coupling element. In each case there is a free end of the first
- the coupling element may, for example, comprise two interconnected suspension end connections, which may for example be designed according to EP 1634842 A2.
- the two TragstoffendENSen can be connected for example via an intermediate piece, with which they can be screwed or welded, for example.
- the coupling element may also have a one-piece housing.
- both coupling elements of each support means are as
- the coupling elements are designed in particular identical. This allows the use of as many equal parts, which allows for a lower manufacturing costs and on the other hand makes the assembly easier, since all coupling elements can be mounted the same or must.
- the support means are designed as belts. Belts have excellent traction characteristics and are particularly suitable for
- the belts can be designed, for example, as flat belts, V-ribbed belts or toothed belts and can be provided with tensile reinforcements in the form of wire ropes, synthetic fiber ropes or
- the suspension means consists of one or more ropes, in particular Drah sculpture.
- the coupling elements are guided in a shift in the elevator shaft.
- the guide used for this purpose is in particular designed so that it prevents a striking of the coupling elements to a passing elevator car. This allows a particularly comfortable and safe operation of the elevator system.
- a shift of an elevator car in the elevator shaft can not be completely ruled out that the suspension element and thus the not connected to an elevator car coupling element is set in vibration.
- Without a guidance of the coupling element there would in particular be the risk that the coupling element strikes against the elevator car when driving past it. Such a striking would lead to an audible shock on the one hand and on the other hand could cause damage to the elevator car and / or the coupling element. This danger is avoided by the leadership of Ankoppeletti.
- each elevator car has two coupling devices. These are intended to simultaneously couple to Ankoppel comprise two different suspension elements.
- the drive machines of the two suspension elements are controlled synchronized, so that both support means are synchronously driven and moved.
- the two coupling devices of an elevator car are arranged in particular on opposite sides of the elevator car. In particular, they are intended to be coupled at diagonally opposite positions to a respective coupling element of a suspension element. This allows a particularly uniform or even distributed force introduction into the elevator car, which allows a very small tilting of the elevator car during the relocation. This is on the one hand a comfortable method of the elevator car possible and on the other guides of the elevator car are little loaded, which is a simple and
- the two coupling devices are in particular not mechanically coupled, but are controlled accordingly by the elevator control.
- Coupling devices are particularly so when coupling to the two support means positioned such that a connecting line at the height of the center of gravity of the elevator car between the two coupling elements of the support means through said
- Focus is on. This allows a particularly uniform force introduction into the elevator car.
- each elevator car has only a single coupling device.
- the elevator car can then only be coupled to a suspension element and be displaced by means of this in the elevator shaft.
- the first and the second elevator car are also displaceable in a vertical direction in a second elevator shaft arranged parallel to the first elevator shaft.
- the elevator system also has a first transfer device, by means of which elevator cars can be moved from the first elevator shaft into the second elevator shaft, and a second transfer device, by means of which elevator cars can be moved from the second elevator shaft into the first elevator shaft. A shift of the elevator cars in the second
- Elevator shaft is realized analogous to the displacement in the first elevator shaft.
- the elevator cabins are displaced only from the bottom upwards in the first elevator shaft and only from the top downwards in the second elevator shaft. In this case, it is irrelevant which elevator shaft is designated as the first and which as the second elevator shaft.
- the provision of the second hoistway and the two transfer devices advantageously allow a circulating operation of the elevator system.
- the transfer devices are in particular in the area of the end positions of
- Elevator cabins arranged. If, for example, an elevator car reaches the upper end position during a displacement in the first elevator shaft, then it becomes After all passengers have left the elevator car and it has disconnected from the suspension means, horizontally displaced by means of the upper transfer means in the upper end position of the second elevator shaft. Subsequently, it can be coupled to a suspension in the second elevator shaft and so be moved in the second elevator shaft down to the lower end position. From there, it will turn horizontally from the lower transfer device to the lower end position of the first
- Lift shaft shifted, from which they can be moved back up.
- the transfer devices can be designed in particular according to the transfer devices in the form of horizontal displacement units of EP 2219985 Bl.
- the transfer device has a vertical guide rail piece that guides the elevator car in the transfer device.
- the transfer device is positionable such that the guide rail piece is a portion of a
- Vertical guide rail forms, from which the elevator car is guided during a displacement in a hoistway.
- the elevator car then has a braking device with which the elevator car can be temporarily fixed to the guide rail piece integrated in the transfer device during the displacement between the elevator shafts.
- Elevator shaft each an equal number of support means, each with two
- a number of the elevator cars is at most equal to a total number of the suspension means of the elevator system.
- the number of elevator cars is in particular exactly the same size as the total number of suspension elements. This means that the number of coupling elements per elevator shaft is greater than or equal to the number of elevator cars to be relocated in an elevator shaft. This allows each elevator car in each of the two elevator shafts a specific
- each elevator car requires only one or, with simultaneous coupling to two coupling elements, only two
- Coupling devices which are each arranged at a fixed position.
- the coupling devices are thus not transversely displaceable to the actuating direction of the bolt of the coupling devices. This allows a cost-effective implementation of the coupling devices.
- the coupling device in this case require very little space.
- Suspension means) per elevator shaft of the first elevator car, the left coupling element of the left suspension element, the second elevator car, the left coupling element of the right suspension element, the third elevator car, the right coupling element of the left suspension element and the fourth elevator car, the right coupling element of the right suspension element are assigned. These assignments are the same in both elevator shafts.
- the coupling element associated with an elevator car is thus arranged in the same position in both elevator shafts. This requires, for example, the first
- Elevator car only a coupling device which is positioned so that it can only couple to the left coupling element of the left suspension element.

- Elevator shaft 12 the upper end position 22 and the second elevator car 16 in the second elevator shaft 13 has reached the lower end position 18. Since in the first elevator shaft 12 the elevator cars 14, 16 are displaced only upwards and in the second elevator shaft 13 only downwards, both elevator cars 14, 16 have to perform a shaft change.
- the elevator system 10 has a first, upper transfer device 70, by means of which the first elevator car 14 can be displaced from the first elevator shaft 12 into the second elevator shaft 13 at the upper end position 22.
- the first transfer device 70 has a vertical
- Transfer device 70 leads.
- the first transfer device 70 is positioned before the start of the displacement such that the guide rail piece 72 forms a portion of the vertical guide rail 24 of the first elevator shaft 12, from which the first elevator car 14 is guided during a displacement in the first elevator shaft 12.
- the first elevator car 14 has a braking device 74 with which the first elevator car 14 is integrated with the one integrated in the first transfer device 70
- Elevator shaft 12 and the second elevator shaft 13 is temporarily fixed.
- the elevator system 10 also has a second, lower transfer device 76 for moving the second elevator car 16 in the lower end position 18 from the second elevator shaft 13 into the first elevator shaft 12.
- the second, lower transfer device 76 for moving the second elevator car 16 in the lower end position 18 from the second elevator shaft 13 into the first elevator shaft 12.
- Transfer device 76 is designed analogously to the first, upper transfer device 70.
- the second elevator car 16 also has a braking device 74.
- the transfer devices 70, 76 can in particular according to the
- Transfer devices in the form of horizontal displacement units of EP 2219985 Bl be executed.
- Fig. 5c the situation after moving the two elevator cars 14, 16 is shown.
- the first elevator car 14 is positioned in the second elevator shaft 13 at the upper end position 22 and the second elevator car 16 in the first elevator shaft 12 at the lower end position 18.
- the now arranged in the first elevator shaft 12 at the lower end position 18 second elevator car 16 is now coupled via its coupling device to the second, in Fig. 5c left coupling element 44 of the support means 26.
- the first, in Fig. 5c right coupling element 44 of the support means 26 is arranged on the support means 26 that a coupling device of a located at the upper end position 22 elevator car could decouple to the second coupling element 44.
- the drive machine 34 For displacing the second elevator car 16 upwards, the drive machine 34 now drives the upper deflection roller 30 in the clockwise direction.
- the drive machine 34 is thus controlled by the elevator control so that the direction of movement of the support means 26 is reversed for the next shift of an elevator car, if a
- Elevator car has reached the lower end position or the upper end position.
- the second elevator car 16 is displaced with possible intermediate stops on floors between the lower end position 18 and the upper end position 22 to the upper end position 22. Simultaneously with the displacement of the second, in Fig. 5c left coupling element 44 upwards, the first, in Fig. 5c right
- Coupling 44 moves down.
- the first elevator car 14 is located in the second elevator shaft 13 in FIG. 5c It is coupled via its coupling device to the second, in Fig. 5c right coupling element 44 of the support means 26.
- the first, in Fig. 5c left coupling element 44 of the support means 26 is arranged on the support means 26, that a coupling device of a located at the lower end position 18 elevator car could decouple to the second coupling element 44.
- the drive machine 34 In order to shift the first elevator car 14 downwards, the drive machine 34 now drives the upper deflection roller 30 likewise in the clockwise direction. In comparison with FIG. 5a, therefore, there is also a reversal of the direction of movement of the suspension element 26.
- the first elevator car 14 is displaced with possible intermediate stops on floors between the upper end position 22 and the lower end position 18 to the lower end position 18. Simultaneously with the displacement of the second, in Fig. 5c right
- the elevator system it is also possible for the elevator system to have a third elevator shaft in which elevator cars that are currently not required can be parked.
