Patent number: 6269910Abstract: An elevator rescue system includes a power source of back-up electrical power. A manually-operated, rescue enable switch switchably permits the transmission of electrical power from the power source to a motor brake coil of an elevator car during a rescue operation such that the energized coil releases the motor brake to move the car to a desired landing. A speed detector measures the speed of the elevator car and thereupon generates a speed control signal corresponding to the speed of the car. An overspeed detection circuit has a first input for being actuated when receiving electrical power from the power source, a second input for receiving the speed control signal, and an output for transmitting electrical power to the motor brake coil when the speed control signal is below a predetermined value and for automatically stopping the transmission of electrical power when the speed control signal becomes higher than a predetermined value. A manually-operated brake release switch has an input and an output.Type: GrantFiled: July 20, 2000Date of Patent: August 7, 2001Assignee: Otis Elevator CompanyInventors: Richard N. Fargo, Gerard Sirigu, Helmut Schröder-Brumloop, Joseph J. Barna, Barry G. Blackaby

Patent number: 6193018Abstract: An elevator system includes a counterweight-drive assembly (26) having a motor (32) and drive pulley (36) mounted internally to engage a drive belt (42) for climbing or descending with respect thereto, resulting in raising or lowering of an elevator car (12) coupled to said counterweight-drive assembly (26).Type: GrantFiled: February 2, 2000Date of Patent: February 27, 2001Assignee: Otis Elevator CompanyInventors: Helmut Schröder-Brumloop, Jean Marc Ferrary, Armando Servia, Pascal Rebillard, Richard J.

Patent number: 6186281Abstract: An elevator overspeed system designed to work as a governor includes a first switch responsive to an overspeed condition and a second, remotely located switch responsive to said first switch. An overspeed elevator control procedure is initiated when one of the first or second switches are tripped. The first switch is automatically re-set after the second switch is tripped. The second switch is manually re-set to re-start the elevator system in normal operation mode.Type: GrantFiled: April 1, 1999Date of Patent: February 13, 2001Assignee: Otis Elevator CompanyInventors: Chris Pietrzykowski, Gerard Sirigu, Richard N. Fargo, Randy G. Henley, Helmut Schröder-Brumloop, Gurumurthi Ravishankar

Patent number: 6161656Abstract: An elevator system includes an electronic driver which transmits a multi-phased electric current through a relay to a motor driving an elevator car. Under normal operating conditions, the motor uses the current from the driver to move the elevator car in a hoistway. When electric power fails, the elevator car is moved by gravity for any necessary rescue or maintenance operations, and consequently moves the motor. The movement of the motor generates a multi-phased electric current therein. The generated current is utilized to power a display panel of a movement indicator, which is automatically connected to the motor by the relay when power fails in the elevator system. The powered display panel informs the operator of the direction and speed of travel of the elevator car.Type: GrantFiled: February 1, 1999Date of Patent: December 19, 2000Assignee: Otis Elevator CompanyInventors: Herbert Horbrugger, Michael Mann, Helmut Schroder-Brumloop

Patent number: 5587565Abstract: An apparatus for controlling an elevator door includes a three phase AC motor that receives control signals from a controller. The signals are issued at control points along a speed versus distance profile map that represents the control points as a percentage of the total distance to be travelled by the elevator. The total distance of door travel in one direction is measured be counting the number of pulses generated by an incremental encoder during a training run wherein the door is moved between its extreme positions at a constant speed. The number of pulses counted is then normalized to represent 100% of the distance traveled. During operation, the pulses are counted whenever the elevator door is in motion and control signals are issued based upon the number of pulses counted.Type: GrantFiled: April 14, 1994Date of Patent: December 24, 1996Assignee: Otis Elevator CompanyInventors: Helmut Schroder-Brumloop, Rudiger Lob
