    The invention relates to an elevator system with a door system that includes a roller door.
    [0002] Elevator systems usually include an elevator car that can be moved vertically in an elevator shaft, the elevator shaft connecting several floors to one another. The elevator shaft has a plurality of shaft door openings arranged one above the other, with a separate shaft door being installed at each of these shaft door openings. The elevator car has a car door opening on its front surface. The elevator car can be positioned in the elevator system by means of a method in such a way that the car door opening is arranged on one of the shaft doors. In order to be able to enter the elevator car from the floor, the shaft door on which the elevator car is arranged and, if necessary, the car door must be opened.
    [0003] In the past, a large number of elevator systems were designed in such a way that this car door opening could not be closed separately by a car door arranged on the elevator car. This means that the elevator car was open and without a car closure. For a passenger in the moving elevator car, this means that the elevator car is delimited in the area of the car door opening by a shaft wall of the elevator shaft that is moved along the car door opening.
    [0004]Due to more recent regulations, however, it is now prescribed that such a cabin door opening must be provided with a cabin closure in the case of a modernization that goes beyond a repair. This means that the elevator car must be lockable in the area of its car door opening, ie it must be delimitable by a car door panel. However, the mass of the elevator car changes significantly as a result of a subsequent installation of such a car door. This usually requires an exchange of system-relevant components, for example the support element, which usually couples a counterweight to the elevator car, or an exchange of the drive for moving the elevator car.
    [0005] Sliding doors in particular, which are typically used as car doors, have too high a mass to be able to dispense with a time-consuming and costly replacement of essential components of the elevator system.
    WO 2005/070807 shows an elevator system with a car door. This cabin door is designed as a roller door. The disadvantage of this roller door is that the cabin door, which is designed as a roller door, requires a lot of space when it is open.
    It is therefore an object of the invention to develop a door of an elevator system which has small dimensions when the door is open and also enables cost-effective modernization.
    The object is achieved by an elevator installation with a door panel, the door panel closing a door opening when the door system is in the closed state and releasing the door opening when the door system is in the open state, the door panel being a tarpaulin that can be rolled up around a bearing axis, with a wall thickness of the tarpaulin is essentially homogeneous in the rolling direction, (and the elevator system further comprises a safety device arranged at the door opening that can be triggered by passengers or by objects when the door system is closed, the safety device being designed and arranged in such a way that immediately before an alleged contact with the door leaf, stopping the elevator car is triggered or can be triggered.)
    The invention is based on the finding that reinforcement webs arranged parallel to the bearing axis cause large dimensions of the door system when open. This space, which the door system occupies when it is open, cannot be used for other purposes when the door system is closed. The effect of this is that a relatively high part of the cross section of the elevator shaft could not be used for an interior of the elevator car. In contrast to this, the tarpaulin, which is essentially homogeneous in the rolling direction, causes the door system to have small dimensions when it is open. For the purposes of this description, essentially homogeneous means that the tarpaulin has no additional reinforcement web or reinforcement webs parallel to its bearing axis. Accordingly, the tarpaulin has a relatively low flexural strength along its rolling direction, so that the tarpaulin can be rolled up under space-saving conditions. The tarpaulin is preferably formed by a material that can be bent over a surface area.
    In addition, such a roller door has a low mass, so that a large number of components of the elevator system could be retained with the installation of the roller door.
    The use of such a safety device is based on the finding that a door panel belonging to the elevator system forms a closure on the one hand, so that moving components of the elevator system behind the door panel cannot be touched. On the other hand, such a door leaf has an inherent rigidity in order to form a mechanical resistance for safety purposes in the event of unintentional contact by a passenger or an object, for example if the door leaf falls against it. Accordingly, it is ensured that persons or objects do not come into contact with moving objects in the elevator system as a result of an accident.
    Accordingly, the safety device is arranged in such a way that a passenger in the elevator car can trigger the safety device when the door leaf is closed and thus cause the elevator car to stop without actually touching the closed door leaf.
    Consequently, by using such a safety device which, when activated, causes the elevator car to stop, door leaves which do not provide this mechanical resistance can advantageously be used.
    [0014] If the imminent imminent contact of the door leaf by the safety device is detected immediately before an intended journey of the elevator car, “stopping the elevator car” within the meaning of this description is equivalent to a resulting start of the journey of the elevator car at a later point in time.
    In a further development of the elevator system, the flexural strength of the tarpaulin is homogeneous in the rolling direction. This makes it possible for the tarpaulin, ie the door leaf, to be arranged or rolled up in a space-saving manner when the door system is in the open state.
    In a further development of the elevator installation, the flexural strength of the tarpaulin in the rolling direction and transverse to the rolling direction is essentially the same. Due to the safety device used, it is possible that the tarpaulin can be unstiffened in terms of flexural strength or flexural rigidity, regardless of the direction considered, or does not have to be additionally stiffened, as can be achieved, for example, with fiber-reinforced materials or plastics.
    A further development of the elevator system includes a safety device arranged on the door opening that can be triggered by passengers or by objects when the door system is closed, the safety device being designed and arranged in such a way that the elevator car is stopped immediately before the door leaf is supposed to be touched. Such a safety device makes it possible for the tarpaulin, which may not have the rigidity required by the regulations, to nevertheless offer a cabin closure with the necessary safety.
    The safety device can comprise a transmitter unit for emitting a light beam and a receiver unit for receiving the light beam, and the transmitter unit is arranged and aligned in such a way that the light beam runs along the door leaf. By means of such a transmitter unit and such a receiver unit it is possible to avoid a dangerous situation in the area immediately adjacent to the door leaf. Depending on the arrangement of the safety device, the light beam can run inside the elevator car or on the floor along the door leaf.
    In a further development of the elevator system, the transmitting unit and the receiving unit have a maximum vertical distance of 0.4 m, preferably 0.2 m, from a cabin floor of the elevator cabin or a floor. As an alternative to this, the transmission unit and the reception unit can have a maximum vertical distance of 0.4 m, preferably 0.2 m, from an upper edge of the door leaf in the closed state. By means of such arrangements, it is possible to recognize a touch that occurs in the upper or lower area of the door leaf. The risk of injury or damage, which exists due to the pinching of parts of the elevator passenger's body or goods moved by the elevator car between the tarpaulin of the elevator door and the car floor or storey floor, can be minimized as far as possible.
    In a further development of the elevator system, the transmitter unit extends essentially along the entire height on one side of the door opening and the receiver unit extends essentially along the entire height on the other side of the door opening, with several light beams to be detected by the receiver unit being able to be emitted by the transmitter unit. If the transmitting unit or the receiving unit is arranged along the entire height of the door opening, any supposed contact with the door leaf immediately causes the car to stop. Accordingly, the risk of body parts or goods to be transported being trapped can also be efficiently minimized in elevator systems which have elevator cars that can be moved quickly.
    A further development of the elevator installation has an evaluation unit connected to the receiving unit, the evaluation unit being designed in such a way that an interruption of the light beam detected by the receiving unit leads to the elevator car stopping. Such an evaluation unit can bring about controlled braking of the elevator car in a simple manner.
    In a further development of the elevator installation, a door post is arranged to the side of the door opening, the door leaf adjoining the door post in the closed state, the transmitting unit or the receiving unit being arranged on the door post, preferably fixed. Such a door jamb is not necessarily an element recognizable as a door jamb. Accordingly, a door post according to this description is an element of the elevator car which is laterally adjacent to the door leaf that is in the closed state. An exemplary pre-installation of the transmitter unit in question or the receiver unit in question on the doorpost is thus greatly simplified.
    A development of the elevator system has an elevator car with a car door, the door panel being part of the car door. Accordingly, the safety device is arranged in an interior of the elevator car or the light beam that can be transmitted by means of the transmitter unit and received by means of the receiver unit runs within the interior of the elevator car. The interior of the cabin is delimited laterally by the door panel of the cabin door and any cabin walls that may be present. It is advantageous that passengers moving by means of the elevator car are aware of the fact that the elevator car may stop immediately before touching the door leaf.
    In a further development of the elevator system, the door leaf rolled up on the bearing axis has a maximum dimension of 0.5 m, preferably 0.3 m, extending perpendicularly to the bearing axis when the door system is open. By means of such a configuration, the use of roller doors of small dimensions is made possible.
    In a further development of the elevator installation, the bearing axis is arranged horizontally and above the door opening. Such an arrangement of the bearing axis therefore makes it possible for the tarpaulin not to have any reinforcements in order to be able to remain in a closed position of the door system. In addition, the door leaf can remain in the closed state without a door drive motor of the door system having to be supplied with electrical energy. Alternatively, the bearing axis can be arranged horizontally and below the door opening. It is advantageous that such an arrangement saves space. If necessary, the door system can have two door leaves whose bearing axles are arranged horizontally, the bearing axle assigned to a first of the door leaves being arranged above the door opening and the bearing axle assigned to the second of the door leaves being arranged below the door opening.
    Alternatively, the bearing axis can be arranged horizontally and to the side of the door opening. Such an arrangement of the bearing axis enables a small space requirement above or below the elevator car. If necessary, the door system can have a second such door leaf, the bearing axis of which is arranged on the other side of the door opening.
    The invention is explained in more detail below with reference to figures. They show: FIG. 1: an elevator installation with an elevator car comprising a car door and with a plurality of shaft doors arranged essentially one above the other; FIG. 2: a front area of the elevator car in longitudinal section with a car door; FIG. 3: a view of the door system in the closed state with a safety device; FIG. 4: a cross section of a tarpaulin of the door system; and FIG. 5: an exemplary safety device.
    Figure 1 shows an elevator installation 2. The elevator installation 2 comprises an elevator car 4 and a counterweight 8. The elevator car 4 and the counterweight 8 are arranged in opposite directions in an elevator shaft 3, usually vertically movable. The elevator car 4 and the counterweight 8 are connected to one another by means of a support element 6 . The support element 6 is guided over deflection rollers 10 . One of these deflection rollers 10 can be designed as an elevator drive. The elevator car 4 can be moved within the elevator shaft 3 by means of such an elevator drive.
    The elevator shaft 3 is connected by means of shaft door openings 25 to individual floors arranged one above the other. Each of these floors has a floor 20 that can be assigned to this floor. A shaft door 24 is arranged at each of these shaft door openings 25 . The elevator car 4 comprises a car door 26 arranged on a car door opening 25, which car door 26 can be arranged on one of these shaft doors 24 in each case. At its lower end, the car door 26 is delimited by a car floor 22 extending along the cross section of the elevator car 4 . If the car door is arranged on one of the shaft doors 24, the elevator car 4 can be entered through this open shaft door 24 and the open car door 26.
    Figure 2 shows a longitudinal section of an elevator car 4 in its front area. The cabin door 26 comprises a door leaf 16 embodied as a tarpaulin, for example, and a safety device 30, for example. The bearing axis 18 is preferably aligned horizontally and is arranged above the cabin door opening 25 . A car door drive, not shown, can be arranged on this bearing axis 18 . This car door drive can, for example, be designed as an external rotor motor and can be arranged within the winding of the door leaf 16 when the door system is in the open state.
    The cabin door opening 25 is closed by the door panel 16 when the cabin door 26 is in a closed state. In this closed state of the car door 26 , the remaining door panel 16 rolled up on the bearing axis 18 has a dimension T extending perpendicularly to the bearing axis 18 . In the open state of the car door 26 , the door leaf 16 , which is accordingly largely rolled up onto the bearing axis 18 , has a maximum dimension M extending perpendicularly to the bearing axis 18 . This maximum dimension M is less than 0.5 m, preferably less than 0.3 m.
    The safety device 30 comprises a transmitter unit 32 and a receiver unit 34. The transmitter unit 32 and the receiver unit 34 are arranged one behind the other in a lower region of the elevator car 4 directly on the door leaf 16 in its closed state, according to the selected illustration from FIG. The transmission unit 32 is suitable for emitting a light beam, not shown. The receiving unit 34 is suitable for receiving this light beam.
    This light beam can be used to detect whether a person or an object has entered the immediate vicinity of the closed door leaf 16 . If such an object or such a person is detected, it can therefore be concluded that the closed door leaf 16 will be touched or could be touched. In order to ensure the safety of the elevator car 4 moved in the elevator shaft, said detection causes the elevator car 4 to stop. In the arrangement shown, the light beam, not shown, runs along the closed door leaf 16, i.e. parallel to a plane of the door leaf 16.
    In an exemplary interruption of the light beam and the resulting deformation of the door leaf 16 in the direction of the shaft wall on which the door opening 25 of the elevator car 4 is arranged, it may happen that the elevator car 4 is not yet completely stopped. In this way it is possible that the passenger causing the interruption of the light beam or the goods transported in the elevator car 4 causing the interruption of the light beam can touch these projections by bulging the door leaf 16 . In order to prevent injuries to this passenger or dangers from these goods, projections of the shaft wall can be provided with linings aligned along the travel direction of the elevator car 4 .
    A safety device 30 designed in this way can also be used to stop the closing movement or the opening movement of the door leaf 16 when the door system is closed or opened if the light beam is interrupted by the safety device 30 . The door leaf 16 can then be reversed, ie the door system can be opened, such an opening movement preferably being slower than an opening movement without a detected interruption of the light beam.
    FIG. 3 shows a closed door leaf 16 from the perspective of a passenger standing on a floor 20 or on a cabin floor 22 . Correspondingly, the door panel 16 is part of a car door or a shaft door. The door opening or the part of the door leaf 16 visible to the passenger in its closed state is delimited on both sides by a door post 40, 42, above the door opening by a door jamb 37 and below the door opening by the cabin floor 22 or the floor 20.
    A light beam 35.1 runs along a lower end of the closed door leaf 16. This light beam 35.1 is emitted by a transmitter unit 32.1 and received by a receiver unit 34.1. The vertical distance of this light beam 35.1 from the storey or cabin floor 20, 22 is a maximum of 0.4 m, preferably 0.2 m. The receiving unit 34.1 can be arranged on the remaining second door post 42. In addition to or as an alternative to a lower transmitting and receiving unit 32.1, 34.1, a second transmitting unit 32.2 and a second receiving unit 34.2 can be arranged in the upper area of the door opening closed by the door leaf 16. Accordingly, the second transmitter unit 32.2 can be arranged on the first doorpost 40 and the second receiver unit 34.2 can be arranged on the second doorpost 42. The second transmitting unit transmits a light beam 35.2, which can be received by the second receiving unit 34.2. The second light beam 35.2 is preferably 0.4 m, preferably 0.2 m, with a maximum vertical distance from the door header 37 below the door header 37.
    The transmitting units 32.1, 32.2 and the receiving units 34.1, 34.2 can be part of a light curtain which has further transmitting units for emitting additional light beams assigned to these transmitting units and correspondingly further receiving units for receiving these additional light beams. For example, known light curtains can be used, which up to now have usually been arranged in an area between a cabin door and a landing door that is inaccessible to passengers.
    Preferably, a first guide track is arranged on the first door jamb 40 and a second guide track is arranged on the second door jamb 42 . The door leaf 16 can have guide elements which engage in the guide track to guide the door leaf 16 . By arranging such a guide element in the guideway assigned to it, the stability of the door leaf 16 in the closed state of the door system can also be increased. In addition, mass elements can be arranged on the door leaf 16, preferably at its lower end, which enable a uniform movement of the door leaf 16 when the door leaf 16 is being closed.
    The door panel 16 can, for example, have a locking device at its end aligned in the closing direction of the door panel 16, so that the door panel 16 can be locked in the closed state of the door system. If necessary, the closing movement of the door leaf 16 can be accompanied by acoustic or visual warning signals.
    Figure 4 shows an example of a cross section of the tarpaulin, which is designed as a door leaf 16. The tarpaulin 16 has a wall thickness S that is homogeneous in the rolling direction R, which means that this tarpaulin does not have any alternating sections along the rolling direction, with a first of these sections being unreinforced and a second of these sections being reinforced. Accordingly, the tarpaulin has a constant wall thickness along its rolling direction, preferably a homogeneous, ie constant, flexural strength. A cross section running through the tarpaulin along an axis perpendicular to this rolling direction R can preferably also correspond to this cross section of the tarpaulin shown in FIG.
    FIG. 5 shows an exemplary security device 30. The security device 30 comprises a transmitter unit 32 and a receiver unit 34, a light beam 35 being able to be transmitted from the transmitter unit 32 to the receiver unit 34. Both the transmitting unit 32 and the receiving unit 34 are connected to an evaluation unit 36 by means of signal connections 37 assigned to them. If the light beam 35 is not detected by the receiving unit 34 during the movement of the elevator car and thus a signal in the evaluation unit 36 corresponding to this non-detection, the elevator car can be stopped or, if necessary, only slowed down in order to be able to obtain a required level of safety.
