Patent number: 8028807Abstract: A method and device for maintenance of an elevator installation or an escalator installation communicates the presence of a maintenance technician at the elevator or escalator installation to a remote service center. The service center is thus informed about that the maintenance technician has to maintain or is maintaining or has maintained a specific installation and is in a position of checking the quality of this maintenance. The maintenance operations are recorded as a maintenance record and communicated to the service center. For example, the maintenance record contains details about which maintenance technician on which day of the year and for how long has undertaken which maintenance operations on a specific elevator or escalator installation. The quality of a thus detected maintenance can then be compared with a quality standard. In addition, the maintenance operations performed are thus uniquely detected and can be evaluated.Type: GrantFiled: November 7, 2005Date of Patent: October 4, 2011Assignee: Inventio AGInventors: Romeo Deplazes, Christian Bodmer

Patent number: 7500650Abstract: An improved lift system door control or safety circuit utilizes locking devices for the lift shaft doors and lock sensors to monitor the status of the locking devices. The lock sensors are coupled to a lift drive unit control through a data bus, which need not be especially designed as a safety data bus. The lock sensors are repeatedly interrogated at short term intervals. The status of the doors is interrogated on a longer time interval, and such data is also passed to the drive unit control by the data bus. The interrogations are used to determine the operating condition of the locking sensors as well as whether communications or transmission errors are present.Type: GrantFiled: March 17, 2004Date of Patent: March 10, 2009Assignee: Inventio AGInventors: Romeo Deplazes, Philipp Angst

Patent number: 7353914Abstract: A safety system for an elevator installation for the transport of persons/goods in a building and a method for operating an elevator installation with a safety system. Several cages are moved one above the other in a shaft. Each cage is moved by a drive. At least one drive control controls the drives by way of drive control signals. Cage position detecting sensors detect positions of each cage and transmit cage position data to at least one safety control. Access to the shaft takes place by way of opened shaft doors. A lock locks the shaft doors. Lock setting detecting sensors detect settings of the locks of the shaft doors and transmit lock setting data by way of the data bus to the safety control. The safety control ascertains, from the cage position data and the lock setting data, shaft region data with details with respect to shaft regions in which each cage is safely movable.Type: GrantFiled: September 29, 2004Date of Patent: April 8, 2008Assignee: Inventio AGInventor: Romeo Deplazes

Patent number: 7350625Abstract: A shaft monitoring system for an elevator installation includes a contactless sensor enabling recognition from the elevator car whether a shaft door lock and a shaft door leaf are in a correct locked setting. A securing device mechanically secures the shaft door lock in order to prevent opening of the shaft door and is mechanically and/or electromagnetically actuatable from the elevator car. The contactless sensor includes an active sensor part arranged at the car door and a passive sensor part arranged at the shaft door lock to be monitored. The active sensor part interacts with the passive sensor part as soon as the elevator car stops behind the shaft door and the shaft door leaf and the shaft door lock are disposed in the correct locked setting. The active sensor part also can transiently interact with the passive sensor part when the elevator car moves past the shaft door.Type: GrantFiled: September 23, 2004Date of Patent: April 1, 2008Assignee: Inventio AGInventors: Romeo Deplazes, Philipp Angst

Patent number: 7261186Abstract: An elevator, particularly for transporting passengers, has an elevator car guided in an elevator shaft a direct drive motor. The drive motor includes an active primary part at the elevator car and a passive secondary part that is fixed in the elevator shaft and is spaced from the primary part by an air gap. In order to achieve a high power capability, the drive motor is configured as a transverse flux motor that moves the primary part linearly relative to the secondary part under the influence of an electromagnetic propulsive force. The secondary part has at least one rail made of a soft magnetic material and subdivided into a plurality of segments having a predetermined length. The segments are fixed to a wall of the elevator shaft by intermediate elements.Type: GrantFiled: July 30, 2004Date of Patent: August 28, 2007Assignee: Inventio AGInventors: Romeo Deplazes, Jörg Evertz, Thomas Eilinger

Patent number: 7252180Abstract: An elevator system includes an elevator car having a car door, a drive unit for moving the elevator car along an elevator shaft wall provided with shaft doors and a controller for controlling movement of the elevator car along the elevator shaft wall. A separate fault detecting device is mounted in a region of each of the shaft doors and in a region of the car door for generating fault information to controller. A status detecting unit generates to the controller status information about a position and a speed of the elevator car. In the case of a fault in the region of one of the shaft doors, the controller permits operation of the elevator car between those floors that can be reached by the elevator car without having to pass the floor at the shaft door where the fault has occurred.Type: GrantFiled: March 3, 2004Date of Patent: August 7, 2007Assignee: Inventio AGInventors: Romeo Deplazes, Philipp Angst

Patent number: 7201256Abstract: An elevator installation with an elevator case, an elevator shaft, and a drive unit. The elevator cage is installed in the elevator shaft to be movable and is controllable by the drive unit so that the elevator cage can be stopped in different positions in the elevator shaft. The elevator shaft is equipped with a detecting device which detects whether a person is standing in a critical zone in the elevator shaft or is about to go into this. The detecting device is connected with the drive unit so that the elevator installation can be transferred to a special mode of operation in case a person is standing in the critical zone or is about to go into this. The drive unit includes special control equipment which in the special mode of operation stops the elevator cage before it moves into the critical zone. In that case the detecting device and the special control equipment are designed to be operationally safe in order to prevent movement of the elevator cage into the critical zone.Type: GrantFiled: July 3, 2002Date of Patent: April 10, 2007Assignee: Inventio AGInventors: Romeo Deplazes, Philipp Angst
