| 20080236955 | EQUIPMENT AND METHOD FOR CONTROLLING AN ELEVATOR DOOR - An equipment ( | 10-02-2008 |
| 20090120725 | Elevator arrangement - The present invention discloses an arrangement and a method for controlling the power supply of the load of an elevator system. The arrangement comprises at least a monitoring unit ( | 05-14-2009 |
| 20090178889 | ELEVATOR SYSTEM - The invention relates to a safety arrangement of an elevator system and to a method for ensuring safety in an elevator system. The safety arrangement comprises at least one mechanical stopping appliance and the control of the safety arrangement comprises at least one limit value that sets the speed, deceleration or permitted vertical distance from the door zone of the elevator car. In the method for ensuring safety in an elevator system at least one mechanical stopping appliance is fitted to the safety arrangement of the elevator system and at least one limit value that sets the speed, deceleration or permitted vertical distance from the door zone of the elevator car is set for the control of the safety arrangement. | 07-16-2009 |
| 20090255762 | SAFETY ARRANGEMENT OF AN ELEVATOR - The invention relates to a safety arrangement of an elevator and a method for implementing safety spaces in an elevator shaft. The elevator comprises an elevator control system, an elevator motor, a power supply circuit of the elevator motor, and at least one mechanical stopping appliance for preventing movement of the elevator car in the elevator shaft. In the method according to the invention information is read with the control unit from the sensors that measure the position of the landing door of the elevator and possibly information is read from the sensors that measure the position of the door of the elevator car. If it is detected that more landing doors than the door of the elevator car are open, the control unit is switched to the person in the elevator shaft mode and information about the person in the elevator shaft mode is sent with the control unit to the elevator control system. | 10-15-2009 |
| 20090288920 | UNINTENDED MOVEMENT GOVERNOR - The invention relates to an electronic unintended movement governor, which comprises an input for car position data, means for determining the speed of the elevator car, a plurality of limit values for permitted movement of the elevator car, such as the limit value of the maximum permitted speed of the elevator car, and which unintended movement governor also comprises overspeed monitoring for controlling at least one stopping appliance of the elevator car when the speed of the elevator car exceeds the limit value of the maximum permitted speed. The unintended movement governor comprises at least two separate controls for controlling a stopping appliance of the elevator car. Additionally, the invention relates to a method for controlling the aforementioned electronic unintended movement governor. | 11-26-2009 |
| 20090321192 | ELEVATOR SAFETY DEVICE - The invention relates to an elevator safety arrangement and a method for implementing safety spaces in an elevator shaft. The safety arrangement of the invention comprises a mechanical safety device which can be set to a working position to ensure a sufficient safety space in the elevator shaft and an electric safety system for identifying the operating state of the mechanical safety device. According to the method of the invention, detectors comprised in the electric safety system are read by an electric safety controller and, when a functional deviation is detected, one or more stopping devices are actuated to bring the elevator system into a safe operating state. | 12-31-2009 |
| 20100032246 | FAIL-SAFE POWER CONTROL APPARATUS - The invention relates to a fail-safe power control apparatus ( | 02-11-2010 |
| 20100038185 | FAIL-SAFE POWER CONTROL APPARATUS - The invention relates to a fail-safe power control apparatus ( | 02-18-2010 |
| 20100219022 | ELECTRIC MOTOR DRIVE - The invention relates to a switch arrangement of an electric motor drive ( | 09-02-2010 |
| 20110114422 | ELEVATOR SAFETY ARRANGEMENT HAVING SAFETY SPACES - An elevator safety arrangement and a method for implementing safety spaces in an elevator has a mechanical safety device which can be set to a working position to ensure a sufficient safety space in the elevator shaft and an electric safety system for identifying the operating state of the mechanical safety device. An electric safety controller comprises means for measuring the total resistance of a series circuit. The method includes reading the number of landing doors open by means of detectors fitted in conjunction with the landing doors, reading the number of elevator car doors open by means of detectors fitted in conjunction with the elevator car doors, and reading the position of a mechanical safety device by means of detectors fitted in conjunction with the mechanical safety device. If it is established that number of landing doors open is greater than the number of elevator car doors open, then setting the safety system into a ‘person in shaft’ state and preventing operation of the elevator. If it is established during the ‘person in shaft’ state of the safety system that the number of landing doors open is equal to the number of elevator car doors open and that the mechanical safety device has been set to a working position, then allowing maintenance operation. | 05-19-2011 |
| 20110162913 | ELEVATOR SYSTEM, AND METHOD IN CONJUNCTION WITH AN ELEVATOR SYSTEM - An elevator system and a method for accelerating the starting of travel in an elevator system are provided. The elevator system includes an elevator control system for implementing controlled motion of an elevator car; a door mechanism control system for implementing controlled movement of the elevator car door; and a door coupler, for forming a mechanical coupling between elevator car door and landing door; and a controller of fast start of travel, which has an input for elevator car position data, an input for landing door position data, an input for car door position data, and at least one output for activating the elevator motor power supply circuit and the elevator brake release circuit. | 07-07-2011 |
