Definitions

  • the present invention relates to a car arrangement for a double-decker elevator and a double-decker elevator with such a car arrangement.
  • a double-decker elevator is characterized by a car arrangement with a car frame and two cabins arranged one above the other. These two cabins allow two different floors to be reached simultaneously.
  • the floors are of different heights, resulting in different vertical distances between the elevator entrances.
  • this vertical distance at least one of the two cars can be moved vertically relative to the other car and, as a rule, relative to the car frame. This vertical displacement is achieved using a displacement device.
  • the displacement device can, for example, have one or more screw spindle drives and/or scissor-like connecting links, via which the two cars are connected to each other.
  • a spindle drive has at least one spindle and a rack, into which the spindle engages.
  • the spindle can be arranged on the car frame of the car arrangement or on the car to be moved.
  • the rack can accordingly be arranged on the car to be moved or on the car frame.
  • a hydraulic displacement device can be provided for moving the cabin. The distance between the cabins can be adjusted during travel using a control system to match the floor spacing between the two floors to be reached and the corresponding distance between the entrances.
  • EP 3 514 096 A1 Describes a double-deck elevator with two cars, where the vertical distance between the cars can be adjusted using a pull chain and several deflection elements. The corresponding drive device increases the height of the corresponding car arrangement.
  • EP 3 514 096 A1 discloses a car arrangement according to the preamble of claim 1.
  • US 2020 / 0 239 289 A1 describes a push chain in which chain links of the push chain engage with each other in such a form-fitting manner under pressure load that a force-absorbing section of the push chain is stable under the pressure load in a direction in which the chain links can be pivoted against each other in the absence of pressure load.
  • WO 2015/043766 A1 Describes an elevator with two cars, each of which can be moved independently of each other in an elevator shaft by means of a drive.
  • the cars can be temporarily coupled together using a mechanical coupling element, for example, in the form of a support chain.
  • the distance between the coupled cars is adjusted using the drives assigned to the cars.
  • the size of the elevator shaft plays a key role.
  • the relocation device should have as little space as possible, especially horizontally.
  • both of the aforementioned relocation devices require a relatively large amount of space, both horizontally and vertically, with the space available in an elevator shaft, particularly horizontally, generally being very limited.
  • the hydraulic relocation device can cause odors due to the oil used in it. can tend to, whereby the smell may be unpleasant in the corresponding cabin.
  • One of the challenges in the design of such double-decker elevators is to design components for moving and driving the cabin to be moved in a way that is as space-saving as possible and, in addition, lightweight and cost-effective.
  • a car assembly for a double-deck elevator that allows the distance between an upper car and a lower car to be adjusted using a particularly compact and lightweight displacement and drive device. Furthermore, there may be a need for a corresponding double-deck elevator.
  • a first aspect of the invention relates to a car assembly for a double-deck elevator.
  • the car assembly comprises a car frame, a first car, a second car, a push chain, and a drive device.
  • the first car is coupled to the car frame.
  • the second car is arranged on the car frame above or below the first car.
  • the second car is coupled to the car frame such that it is movable vertically relative to the car frame and relative to the first car.
  • the push chain is coupled to the first car or the car frame by a first end of a force-absorbing section of the push chain. Furthermore, the push chain is coupled to the second car by an opposite second end of the force-absorbing section.
  • the push chain is arranged such that the second car exerts a compressive load on the force-absorbing section of the push chain due to gravity.
  • the drive device is coupled to the push chain and is designed to displace the second car vertically relative to the first car by means of the push chain.
  • the second car which is arranged in the car frame above or below the first car and is movable in the vertical direction, can be displaced vertically relative to the first car, so that the vertical distance between the cars is adjustable, in particular depending on the corresponding access points to the cars on different floors of a building.
  • the vertical distance is adjusted in particular by changing the length of the force-absorbing section, wherein this length is achieved by moving the push chain by means of the drive device.
  • car frame can generally be understood as a frame that can be moved between several levels or floors, for example in an elevator shaft, and has at least one cabin, or in the present case of a double-decker elevator with at least two cabins, for transporting people or loads.
  • the car frame can in particular be a frame-like construction for supporting the cabins and is also called a safety frame.
  • the car frame can, for example, be guided along at least one guide rail running in an elevator shaft. Such guide rails can be arranged on one side or on two opposite sides of the elevator shaft.
  • a safety gear can be integrated into the car frame and serves to slow the car frame down in the event of excessive speed.
  • the car frame can comprise the two double-decker cars for simultaneously accessing the two different floors.
  • a displacement device can be arranged, by means of which at least one of the two cars can be displaced in the vertical direction relative to the other car and, as a rule, relative to the car frame.
  • the aforementioned drive device and the push chain form such a Displacement device.
  • the approach presented here proposes displacing the second car using a push chain. The vertical distance between the cars is determined by the length of the force-absorbing section of the push chain.
  • This length can be adjusted using the drive unit, thereby displacing the second car relative to the first car.
  • a guide structure is also installed within the car frame, in which the two cars are arranged one above the other, to guide the car to be displaced during its movement.
  • the weight of the second cabin acts on the push chain.
  • the second cabin can stand on the push chain.
  • the section of the push chain on which the weight acts and which accordingly supports the weight of the second cabin is the force-absorbing section.
  • the push chain In order for the length of the force-absorbing section to be variable, the push chain must be longer than the force-absorbing section.
  • the section of the push chain on which the weight of the second cabin does not act can be referred to as the remaining section of the push chain.
  • the length of the remaining section changes depending on the length of the force-absorbing section. In particular, the length of the remaining section increases as the length of the force-absorbing section decreases, and vice versa.
  • the push chain exhibits shock properties when the second cabin is lifted. Therefore, the push chain cannot break.
  • the push chain and the drive device that drives it require relatively little space, especially in the horizontal direction, compared to the spindle drive and the hydraulic displacement device.
  • the drive device can generally be understood to mean a motor by which the push chain is moved in such a way that the length of the force-absorbing section of the chain changes, so that the corresponding car, for example the second car, can be raised and/or lowered relative to the car frame and the first car.
  • the push chain can be designed in such a way that chain links of the push chain engage with each other in a form-fitting manner under a pressure load, such that the force-absorbing section of the push chain under the pressure load in a direction in which chain links of the push chain can pivot against each other in the absence of pressure load, is stable.
  • the push chain can always be stable in a first lateral direction, which is perpendicular to a longitudinal direction of the push chain when the push chain is unwound, and can be unstable, in particular pivotable, in particular bendable, at the transition of the chain links in a second lateral direction, which is perpendicular to the longitudinal direction of the push chain and perpendicular to the first lateral direction when the push chain is unloaded and/or unwound.
  • the chain links of the push chain can engage with one another in a form-fitting manner under compressive load such that the push chain is stable in the second lateral direction. The push chain can thus withstand high compressive loads.
  • the drive device can be designed and coupled to the push chain in such a way that when the second cabin is displaced in the direction of gravity, the push chain drives the drive device in a generator-like manner.
  • the potential energy stored in the raised second cabin can be converted into electrical energy by means of the push chain and the drive mechanism in generator mode.
  • the weight of the second cabin acts on the push chain, which drives the drive mechanism, which in turn acts as a generator and generates electrical energy.
  • the electrical energy can be stored and reused, for example, to power the drive mechanism the next time the second cabin is moved.
  • the drive device can comprise the motor and an output arranged on a shaft of the motor and engaging with the push chain.
  • the output can be formed, for example, by a gear whose teeth engage with the chain links of the push chain.
  • the drive device can further comprise a housing and/or a guide for the remaining section and optionally a part of the force-absorbing section of the push chain.
  • the motor and/or the remaining section can optionally be arranged in or on the housing.
  • the drive device can be arranged on the first car or on the second car.
  • the drive device can be arranged on the car frame or on the second car.
  • the drive device can engage the push chain at the first end of the force-absorbing section or at the second end of the force-absorbing section.
  • the push chain can be arranged such that the remaining section of the push chain, which is not the force-absorbing section, is located between the cabins. This is particularly advantageous when the push chain is coupled to the first cabin. For example, if the push chain is coupled to the first cabin, the remaining section can be guided along the cabin on which the drive device is arranged.
  • the push chain can be arranged such that the remaining section of the push chain extends at least partially in the horizontal direction. This can contribute to the particularly small vertical space requirement of the relocation device.

  • the car frame can have the first force-absorbing region.
  • the second car can have a second force-absorbing region.
  • the push chain can be coupled to the first force-absorbing region by the first end of the force-absorbing section and to the second force-absorbing region by the second end of the force-absorbing section.
  • the force-absorbing section can extend from the first force-absorbing region to the second force-absorbing region. A vertical distance between the two cars depends on a length of the force-absorbing section.
  • the drive device can be designed to move the push chain in order to displace the second car in the vertical direction such that the length of the force-absorbing section changes.
  • the second force-absorbing region is the region where the weight of the second car is transferred to the force-absorbing section of the push chain.
  • the first force-absorbing region is the region where the corresponding compressive load is transferred from the force-absorbing section to the first car or the car frame.
  • the drive device can be arranged at the first end or at the second end of the force-absorbing section. At the end of the force-absorbing section at which the drive device is arranged, the drive device, for example its output, can form the corresponding force-absorbing region.
  • a rotatable deflection device for example a gear wheel that engages with the push chain, can be arranged at the first end or at the second end of the force-absorbing section. In this case, the deflection device can form the corresponding force-absorbing region.

  • the car assembly can have a further drive device coupled to the further push chain.
  • the further drive device can be configured to displace the first car in the vertical direction relative to the car frame by means of the further push chain.

  • the additional push chain for displacing the first car can be referred to as the first push chain
  • the push chain for displacing the second car can be referred to as the second push chain.
  • Displacing the first car in addition to displacing the second car allows for greater flexibility and/or greater speed with regard to adjusting the vertical distance between the cars depending on the different floor heights.
  • the car assembly for vertically displacing the second car may comprise exactly one single push chain.
  • two or more push chains for example four push chains, must be arranged. If two or more push chains are used to move the corresponding car, the drive devices for adjusting the corresponding push chains must be synchronized with one another to prevent the corresponding car from tipping and/or jamming. Arranging just a single push chain to move the second car, however, makes it possible to dispense with this synchronization. This contributes to the car arrangement being particularly simple and cost-effective to manufacture when only a single push chain is used.
  • the push chains can engage two diametrically opposed corner sections of the corresponding cabin.
  • a second force-absorbing area can be arranged at each of the diametrically opposed corner sections of the second cabin.
  • Two diametrically opposed corner sections can be understood as two corner sections of the corresponding cabin, each of which lies on a diagonal of the underside of the corresponding cabin.
  • the lifting force can be understood as a force for raising and/or lowering the corresponding cabin. This design can minimize torsion of the corresponding cabin due to loads during displacement.
  • a second aspect of the invention relates to the double-decker elevator.
  • the double-decker elevator comprises the above-described car assembly and a control device configured to control the drive device of the car assembly depending on the floor distance between a first floor and a second floor such that, in a stop position of the car assembly, the first car is accessible via the first floor and the second car via the second floor is accessible.
