  • Patent number: 10713912
    Abstract: An access-monitoring device of an elevator installation includes at least one video unit, wherein the video unit is connected to a control unit via a communications network. The video unit records at least one image of a defined monitoring space of the access-monitoring device. The video unit filters out a non-changing part of the at least one image and evaluates the remaining image part as to whether there is an object in the monitoring space. In the case of there being an object in the monitoring space, the video unit communicates data to the control unit. The control unit checks, in dependence on the data communicated, the authorization of the object in the monitoring space and determines either the direction of movement or the location of the object within the monitoring space.

  • Patent number: 10696522
    Abstract: A method for refinishing a surface structure of shaft material of an elevator, which extends along a shaft, enables the use of image data to determine an absolute position and/or speed of an elevator car. The elevator includes the elevator car, which is movable in the shaft, a camera, which is arranged at the elevator car and generates the image data from the surface structure, and an evaluating unit, which determines the absolute position and/or the speed of the elevator car from the image data. The surface structure is refinished at least locally in order to increase a distinctiveness of the surface structure in the image data. The shaft material can be, for example, a guide rail, a fastening element of the guide rail, or a shaft wall.

  • Patent number: 10662025
    Abstract: An operating panel for an elevator includes a panel plate having an opening, a key switch arrangement and, optionally, a human machine interface attached to the panel plate. The switch arrangement includes a cover arrangement, a hinge and a key switch. The key switch is attached to the cover arrangement and is activated or deactivated by a key for transmitting activation signals to the elevator control upon activation. The cover arrangement is attached to the panel plate via the hinge and is displaced between a first configuration in which the key switch is arranged behind the cover arrangement and a second pivoted configuration in which the key switch is accessible from the front side of the panel plate. Thus, the key switch is protectively stored in the first configuration, providing splash water protection and an attractive visual appearance, and is pivoted to the second configuration when needed.

  • Patent number: 10577808
    Abstract: In a method for modernizing a building, a former stairwell of the building is converted such that an elevator shaft of an elevator system to be constructed can be provided in the former stairwell. The elevator shaft is provided in the former stairwell of the building such that stepless access is facilitated to specific floors of the building from an elevator car of the elevator system, which car can be provided in the elevator shaft. A new staircase is constructed outside the former stairwell. In addition, a former staircase is removed from the former stairwell. Furthermore, access bridges are disposed next to the elevator shaft in the former stairwell, thereby enabling flush access from the new staircase to the specific floors.

  • Patent number: 10577220
    Abstract: A position-determination system for an elevator uses a camera arranged on an elevator car, which camera has a sensor with a defined number of light-sensitive pixels for generating image data of a surface structure of hoistway material arranged along a travel path of the elevator car. An analysis unit, based on the image data, determines a position and/or velocity of the elevator car. The position-determination system recognizes a reference pattern with a specified dimension which lies in a capturing range of the camera, wherein, based on the reference pattern, the analysis unit performs a scaling of the image data.

  • Patent number: 10562738
    Abstract: An elevator system has a drive, a car, a plurality of safety function components for providing safety functions at various positions, and a safety monitoring system with a plurality of safety monitoring units for monitoring all of the safety function components. The monitoring units have an input interface for reading in data or signals and an output interface for outputting control signals to an assigned member of the safety function components, at least some of the monitoring units being connected via data exchange channels. The monitoring units are organized in a master-slave hierarchy, with one unit designed as a master unit, and at least one other unit designed as a slave unit. The decentralized and distributed monitoring units, each having data processing capability, and the master-slave organization result in the elevator system exhibiting a high security level with low cabling complexity and cost expenditure, in particular for high rise elevators.

  • Patent number: 10562737
    Abstract: A lift system for protecting the privacy of passengers. The lift system having a lift car that can be moved between floors of a building. The lift car having a video camera arranged in the lift car. The video camera being a part of a video system that also includes a video monitor for displaying information relating to the interior of the lift car. A video control device is communicatively connected to and controls the video system in a selective manner according to one of several operating modes. The several operating modes include a first operating mode in which the video system is deactivated or activation is blocked, so that the video system remains in an inactive state, if a passenger asks for the video system to be deactivated. When in the first operating mode the video system remains in the inactive state for as long as the passenger is in the lift car.

  • Patent number: 10562133
    Abstract: What is described is a method for producing a framework-like supporting structure for a passenger transport system, such as a moving staircase, in which an entire production sequence is divided into at least three separate joining steps which can be performed by coordinated semi- or fully automated joining stations that cooperate with each other. Each of the joining stations comprises at least one retention device and at least one welding robot, as well as optionally at least one handling robot. The joining steps to be performed in the individual joining stations are configured so that interim products can be produced efficiently and harmonized with a subsequent joining step in a subsequent joining station. Interim products can be forwarded sequentially and at optimized, short intervals from joining station to joining station, to be able to provide a finished, load-bearing supporting structure at the end of the sequence.

  • Patent number: 10556774
    Abstract: A method and an arrangement for determining elevator data based on the position of an elevator car of an elevator system includes the elevator car having a flag reading sensor, the elevator car being movably arranged in a hoistway and can be moved by a drive with a suspension rope over a traction sheave, and the elevator car can be stopped at a plurality of stopping positions of the hoistway. Each stopping position has a flag marker with a flag height. Movement of the elevator car is determined by a control unit connected to an encoder at the traction sheave. When leaving a stopping position, the travelled distance of the elevator car between the stopping position and a flag edge is measured and a stopping inaccuracy is determined by the control unit.
