  • Patent number: 11034550
    Abstract: A method for constructing an elevator system in a building includes performing at least one lifting operation to adapt a usable lifting height of the elevator system to an increasing height of the building. A drive platform supporting an elevator drive machine and, by a flexible support, an elevator car and a counterweight is raised during the lifting operation. A difference between an elevator-car-side support weight and a counterweight-side support weight is substantially compensated by a compensating tension device guided from a bottom side of the elevator car to a bottom side of the counterweight by a deflecting device including two roller assemblies having deflecting rollers forming a compensating tension loop. A distance between the roller assemblies is reduced before and/or during the lifting operation such that an amount of the compensating tension device required for the performance of the lifting operation is released from the compensating tension loop.

  • Patent number: 11027945
    Abstract: A wall securing assembly is integrated into an elevator shaft wall for securing a guide rail to the wall. The wall has a first concrete region that is reinforced with reinforcements and a second concrete region that is not reinforced. The second region covers the first region and has a surface that is exposed to the surroundings. The securing assembly has an elongated profile of C-shaped cross-section embedded solely into the second region and oriented in the vertical direction of the wall. Since tensile forces acting on a guide rail in an elevator shaft are very low, it is acceptable to secure the guide rail to the profile that is cast into the second region covering the reinforcement. The profile is anchor element-free and can be arranged in the wall vertically whereby guide rail holding consoles can be secured to the profile at any height.

  • Patent number: 10926974
    Abstract: An elevator system drive unit moves an elevator car in an elevator shaft to at least two shaft access doors under control of a control unit. The car does not move or moves only to a limited extent if an individual is in the shaft. A monitoring unit and sensor (switching contact) detect changes in state in at least one of the doors using a sequence of pulses monitoring signal. The monitoring unit has a battery and can be switched to an autonomous mode when the elevator system is entirely or partially disabled. The monitoring unit, in the autonomous mode, records state data from the sensor and is connected to a safeguard unit that reads and evaluates the recorded state data, and prevents the elevator system from being put into the normal mode of operation if a change in the state of one of the monitored doors has been detected.

  • Patent number: 10875745
    Abstract: The application relates to a handrail-drive system of an escalator. The handrail-drive system includes a handrail drive with drive elements and a belt-form handrail which can be moved in a circulatory manner. The handrail is delimited by an outer contour configured as a gripping surface and by an inner contour which leaves a cavity free in the handrail. The driving force is transmitted from the drive elements to the handrail on two mutually opposite side surfaces of the inner contour, wherein a complementary configuration of the side surfaces makes it possible for all the other forces which are caused by the transmission of the driving force and act between the side surfaces to compensate for one another.

  • Publication number: 20200377339
    Abstract: A method for mounting a guide rail in an elevator system elevator shaft first carries out mounting steps by a mounting device having a carrier component, an installation component and a control apparatus controlling the installation component. The control apparatus determines, on the basis of an actual position of the mounting device and a desired position of a guide rail to be installed, a position of a marking on a shaft wall of the elevator shaft relative to the actual position of the mounting device. Based on the marking, an installation step determines the desired position of the guide rail. The marking is applied to the shaft wall by the installation component. The previous steps are followed by the steps of alignment the guide rail in relation to the marking and fastening the guide rail to the shaft wall, which steps can be performed manually by an installer.

  • Patent number: 10836605
    Abstract: An elevator car has at least one balustrade attached to a roof of the elevator car, which balustrade can be pivoted about a rotation axis between a folded-down position, in which the balustrade is arranged essentially horizontally, and a raised position, in which the balustrade is arranged essentially vertically. The balustrade is mechanically coupled to a 3-state switch, which switch can adopt three different switching states. The balustrade and the 3-state switch thus cooperate such that the 3-state switch adopts a first switching state when the balustrade is in the folded-down position, the 3-state switch adopts a second switching state when the balustrade is in the raised position, and the 3-state switch adopts a third switching state when the balustrade is in neither the folded-down position nor the raised position.
