Patent number: 11897731Abstract: A brake device for braking an elevator installation traveling body movable along a guide rail includes a holder mounting a brake element having a brake surface movable relative to the holder between a freewheel position and a braking position. In a deactivated configuration, a pretensioning element does not exert any force moving the brake element towards the braking position, and in an activated configuration exerts such force. In a retaining state, a release element retains the pretensioning element in the deactivated configuration, and when activated into a released state, the release element changes the pretensioning element into the activated configuration. In an unactuated state, a friction-generating element does not abut the guide rail and, in an actuated state generates friction by abutting the guide rail to exert a force on the brake element and force the brake element towards the freewheel position.Type: GrantFiled: December 11, 2020Date of Patent: February 13, 2024Assignee: INVENTIO AGInventors: Michael Geisshüsler, Faruk Osmanbasic, Adrian Steiner, Julian Stähli, Heinz Widmer, Volker Zapf

Patent number: 11891274Abstract: A method and a catching device are used to catch a traveling body in an elevator system wherein traveling body is movable along a rail. The catching device includes a first braking element, a second braking element, a first guide element, a second guide element and an actuating element. The first braking element and the second braking element are brought into contact with the rail for braking. A first linear bearing is formed between the first braking element and the first guide element and a second linear bearing is formed between the second braking element and the second guide element. Both guide elements are moved between a rest position and a braking initial position, the actuating element moving the two guide elements from the rest position into the braking initial position.Type: GrantFiled: November 20, 2020Date of Patent: February 6, 2024Assignee: INVENTIO AGInventors: Michael Geisshüsler, Astrid Sonnenmoser, Faruk Osmanbasic, Adrian Steiner, Christian Studer, Julian Stähli, Volker Zapf, Urs Camenzind

Patent number: 11891275Abstract: A brake device for braking a traveling body movable along a guide rail in a movement direction includes a holder mounting a brake element that has a brake surface directed toward the guide rail, the brake element being movable relative to the holder between a free-running position and a braking position. A pretensioning element is activated to exert a force that moves the brake element toward the braking position. A release element holds the pretensioning element in a holding state and is activated into a released state to reconfigure the pretensioning element from a deactivated configuration into the activated configuration. A pressing element in an actuated state generates a force on the brake element in a direction toward the guide rail to enable a reset of the brake device.Type: GrantFiled: December 1, 2020Date of Patent: February 6, 2024Assignee: INVENTIO AGInventors: Michael Geisshüsler, Faruk Osmanbasic, Adrian Steiner, Julian Stähli, Heinz Widmer, Volker Zapf

Patent number: 11840425Abstract: A safety brake includes a first brake element, a first guide element, and an actuating element. The first brake element is mounted in a displaceable manner in a linear bearing on the first guide element. The first guide element can be moved between a rest position and a braking initial position. The actuating element is designed to move the first guide element from the rest position into the braking initial position, more particularly to activate the safety brake. The first brake element can carry out a braking movement from the braking initial position into a braking position. The braking movement returns the first guide element to the rest position. The first guide element is guided on a first parallelogram guide.Type: GrantFiled: December 11, 2020Date of Patent: December 12, 2023Assignee: INVENTIO AGInventors: Michael Geisshüsler, Faruk Osmanbasic, Adrian Steiner, Julian Stähli, Volker Zapf

Patent number: 11230455Abstract: A method for configuring security related configuration parameters is used in a passenger transport installation that includes at least one sensor exchanging sensor signals with a control. The sensor detects operating parameters within the passenger transport installation and emits corresponding sensor signals. The control controls security related functions of the passenger transport installation taking into account the sensor signals and the configuration parameters. The method includes: comparing the sensor signals with a predefined key signal pattern; operating the control temporarily in a configuration mode exclusively if the compared sensor signals correspond to the key signal pattern; and configuring the security related configuration parameters during the configuration mode. An installation-specific sensor (e.g. optical sensor or magnetic field sensor) functions as an interface to put the control into configuration mode in a targeted manner, e.g.Type: GrantFiled: July 9, 2018Date of Patent: January 25, 2022Assignee: INVENTIO AGInventors: David Michel, Martin Pfister, Michael Geisshüsler, Simon Zingg, Eric Birrer

Patent number: 10781074Abstract: A monitoring device for an elevator system is used with an assembly device for assembling a shaft retrofit and a method for monitoring an assembly platform. The monitoring device monitors movements of an elevator car and includes a sensor system for detecting a movement variable and at least one analysis device that evaluates the detected movement variable and compares it to a threshold. If the threshold is exceeded, a signal output is triggered to actuate a brake/catching device. The monitoring device selects the threshold from specified thresholds based on a state of the monitoring device. The specified thresholds include at least one normal operation threshold, and the monitoring device indicates a normal state as soon as specified connection elements are connected to it. The monitoring device further contains a checking routine for determining a state of the monitoring device, and selects the threshold from specified thresholds based on the state.Type: GrantFiled: September 22, 2016Date of Patent: September 22, 2020Assignee: INVENTIO AGInventors: David Michel, Simon Zingg, Michael Geisshüsler

Patent number: 9926170Abstract: In an elevator installation, an elevator car is movably arranged alongside guide rails and the elevator car is equipped with a brake system with preferably two safety brakes. A movement monitoring system monitors the movement parameters of the elevator car and triggers corresponding warnings or safety measures, if permissible threshold values are exceeded or it provides determined adjusted movement parameters to an elevator control. The movement monitoring system determines a first movement parameter in a time interval and detects an acceleration of the elevator car. The movement monitoring system determines the time interval for determining the adjusted movement parameter as a function of the detected acceleration.Type: GrantFiled: October 22, 2013Date of Patent: March 27, 2018Assignee: INVENTIO AGInventors: David Michel, Eric Birrer, Rudolf J.
