Patent number: 7510059Abstract: A rope brake for an elevator installation for braking a rope coupled to a car is provided, which has a stop that is immovable in the longitudinal direction of the rope and at least one brake shoe. The rope is led between the stop and the brake shoe, and the brake shoe is adapted to be moved back and forth between a braking position, pressing the rope against the stop, and a release position, releasing the rope. A drive coupled to the brake shoe is provided for releasing the rope. The drive is formed as a linear drive and the at least one brake shoe can be transferred by means of the linear drive into its release position against the action of a braking force acting on it in the braking position. Methods for testing a rope brake for an elevator car having a movable brake shoe are also provided.Type: GrantFiled: March 20, 2008Date of Patent: March 31, 2009Assignee: ThyssenKrupp Elevator AGInventors: Guenter Reuter, Walter Nuebling, Wolfgang Meissner, Helmut Schlecker

Patent number: 7448471Abstract: The invention relates to an elevator installation comprising at least one car, which has a safety gear and with which a control unit, a drive and a brake are associated, and further comprising a safety device for avoiding a collision of the car with an obstacle, another car or an end of the shaft, it being possible by means of the safety device to compare an actual distance of the car from an obstacle, another car or an end of the shaft with a minimum distance and a critical distance. If the actual distance goes below the minimum distance, an emergency stop can be triggered. If the actual distance goes below the critical distance, the safety gear of the car can be triggered.Type: GrantFiled: August 31, 2007Date of Patent: November 11, 2008Assignee: ThyssenKrupp Elevator AGInventor: Walter Nuebling

Patent number: 7178635Abstract: An elevator installation with at least one shaft having a plurality of shaft doors is provided. At least two cars disposed one above the other travel up and down in the shaft. Each car has at least one car door. A safety device is provided for blocking the travel of the cars when the shaft doors or car doors are open. The safety device has at least two independent safety circuits, each having at least one shaft door and/or car door associated with it. Travel of at least one car can be blocked by means of the safety circuits.Type: GrantFiled: October 24, 2005Date of Patent: February 20, 2007Assignee: ThyssenKrupp Elevator AGInventors: Wolfgang Meissner, Walter Nuebling

Publication number: 20060175135Abstract: The invention relates to an elevator installation with at least one shaft, in which at least two cars disposed one above the other can be made to travel up and down, the shaft having a plurality of shaft doors and the cars respectively comprising at least one car door, and with a safety device for blocking the travel of the cars when the shaft doors or car doors are open. In order to develop the elevator installation in such a way that its transporting capacity can be increased and the cars hinder one another as little as possible, it is proposed according to the invention that the safety device has at least two independent safety circuits, each having at least one shaft door and/or car door associated with it, it being possible for the travel of at least one car to be blocked by means of the safety circuits. A method for controlling an elevator installation is also proposed.Type: ApplicationFiled: October 24, 2005Publication date: August 10, 2006Applicant: ThyssenKrupp Elevator AGInventors: Wolfgang Meissner, Walter Nuebling

Publication number: 20060157306Abstract: The invention relates to a rope brake for an elevator installation for braking a rope coupled to a car, with a stop that is immovable in the longitudinal direction of the rope and at least one brake shoe, it being possible for the rope to be led through between the stop and the brake shoe, and it being possible for the brake shoe to be moved back and forth between a braking position, pressing the rope against the stop, and a release position, releasing the rope, and with a drive coupled to the brake shoe for releasing the rope. In order to configure the rope brake in such a way that it has a simpler construction and with it the rope can be braked within a short time, it is proposed according to the invention that the drive is formed as a linear drive and the at least one brake shoe can be transferred by means of the linear drive into its release position against the action of a braking force acting on it in the braking position. A method for testing a rope brake of this type is also proposed.Type: ApplicationFiled: January 20, 2006Publication date: July 20, 2006Applicant: ThyssenKrupp Elevator AGInventors: Guenter Reuter, Walter Nuebling, Wolfgang Meissner, Helmut Schlecker

Patent number: 6854564Abstract: An elevator system is provided for the transport of loads and/or persons in an elevator shaft. At least two elevator cars can be moved in the elevator shaft and are connected to a counterweight. A drive is associated with each car. At least one common track section and, in addition, separate track sections arranged next to one another are associated with at least two cars. The common track section and the separate track sections are arranged in sections along the elevator shaft. The cars can be moved not only in the same direction but also in directions opposite to one another.Type: GrantFiled: October 11, 2002Date of Patent: February 15, 2005Assignee: ThyssenKrupp Elevator AGInventors: Guenter Reuter, Wolfgang Meissner, Helmut Schlecker, Walter Nuebling, Martin Kleine-Doepke
