Patent number: 10035683Abstract: An elevator system includes a first elevator car, a second elevator car, a drive-machine, and a suspension apparatus that passes over a traction sheave of the drive-machine to cause the cars to travel one above the other in a travel space. The suspension apparatus is divided into a first set and a second set. A displacement mechanism fixed in the travel space interacts with the second set between the traction sheave and the second car to vary the distance between the cars. This distance can be adjusted independent of the traction sheave. The displacement mechanism can have a pulley arrangement with a displaceable pulley displaced by a displacement drive to vary a length of a section of the second set between the displacement mechanism and the second car.Type: GrantFiled: November 18, 2014Date of Patent: July 31, 2018Assignee: INVENTIO AGInventors: Adrian Steiner, Christoph Schuler, Nicolas Gremaud, René Strebel, Urs Schaffhauser, Marcel Nicole

Patent number: 9617116Abstract: An elevator installation includes an elevator cage with a support construction carrying the elevator cage, wherein the support construction has two beams. Mounted on each beam is a positioning arrangement on which a sensor is positioned, which is part of a load measuring device, wherein the positioning arrangements have material structures. The sensors detect a change in spacing of the material structures from one another, wherein this change in spacing is caused by a change in loading of the elevator cage. Signals of the sensors are processed in an evaluating unit and a signal representing the loading is used in an elevator control.Type: GrantFiled: May 8, 2015Date of Patent: April 11, 2017Assignee: Inventio AGInventors: Beat Brugger, Christoph Schuler, Lukas Zeder, Thomas Wuest, Urs Schaffhauser, Rene' Strebel

Patent number: 9187292Abstract: A support frame has at one or more lower cage corners a respective support, at which at least one damping element is arranged. The support has a U-shaped cross-section and can be inserted into a beam with C-shaped cross-section. The elevator cage is mounted on the damping elements, which can keep oscillations and vibrations away from the elevator cage. Near the inserted support, a device can be provided for raising the elevator cage if the support or at least one damping element has to be replaced.Type: GrantFiled: September 1, 2011Date of Patent: November 17, 2015Assignee: Inventio AGInventors: Beat Brügger, Christoph Schuler, Lukas Zeder, Thomas Wuest, Urs Schaffhauser, René Strebel
