Definitions

  • the present invention relates to a door drive device for elevator systems with a coupling mechanism for transmitting the opening and closing movement of a car door leaf on a corresponding shaft door leaf.
  • An elevator installation usually has two types of doors: car doors and landing doors.
  • an elevator car has at least one car door with one or more doors that opens and closes a corresponding car opening.
  • a landing door with one or more door leaves is installed, which opens and closes a corresponding manhole opening.
  • Each landing door is positioned so that when the elevator car stops at the correct floor level on the corresponding floor, it faces the car door so that the interior of the elevator car is accessible through the landing door and the car door when both doors are open. Normally, the landing door is always closed for safety reasons when the elevator car is not positioned on the corresponding floor.
  • Coupling mechanisms are optionally arranged on the car doors and have, for example, two aligned parallel to the direction of travel of the elevator car, mounted on two pivotable about a pivot axis adjusting elements and thereby in their mutually spaced adjustable Mit psychologykufen acting on at least one arranged on a corresponding shaft door coupling element.
  • the Mit recruitingkufen the coupling mechanism are brought to the at least one coupling element on the shaft door or the landing door hinges, so that the car door is coupled to the shaft door, and after the end of the common closing movement of the doors are the Mit recruitingkufen the coupling mechanism returned to their spaced from the at least one coupling element on the shaft door starting position.
  • the coupling mechanism is connected to a drive for moving the car door. That is, the Mit psychologykufen the coupling mechanism and the car door are both operated by a common drive.
  • two drives are provided: a first drive for moving the car door and a second drive for moving the Mit psychologykufen the coupling mechanism.
  • This second concept basically allows a simpler and more reliable drive for the coupling mechanism independent of the drive for the car door.
  • FIGS EP 0 332 841 A1 and the EP 1 541 518 A1 Examples of door drive devices having a common drive both for moving the car door and for actuating the coupling mechanism are shown in FIGS EP 0 332 841 A1 and the EP 1 541 518 A1 the applicant discloses.
  • the EP 1 524 233 A1 the applicant a door drive device with a second drive for actuating the coupling mechanism in the form of a coupling mechanism itself mounted linear motor and describes the FR 2,827,266 A a door drive apparatus in which a separate drive for actuating the coupling mechanism is formed of a direct current motor provided on the coupling mechanism itself and a gear connection.
  • the present invention is based on the object, a door drive device for elevator systems with a coupling mechanism for transmitting the opening and closing movement of a car door leaf on a corresponding shaft door leaf to provide, in which the operation of the coupling mechanism by a separate drive simple structure is safe and reliable.
  • the door drive device for elevator systems for opening and closing at least one car door leaf and a corresponding shaft door leaf comprises a coupling mechanism mounted on the car door leaf of an elevator car for transmitting the movement of the car door leaf to the landing door wing, the coupling mechanism being aligned two parallel to the direction of travel of the elevator car (one at a time) Swivel axis pivotable) adjusting elements mounted and adjustable in their mutual distance Mit videkufen which act in their spaced-apart coupling position on at least one (arranged on the landing door panel) coupling element and are biased in their spaced-apart coupling position.
  • the device optionally further comprises a first drive device for moving the cabin door leaf; and a second drive device for moving the coupling mechanism between a decoupling position in which the entrainment skids approach each other, and the coupling position in which the Mitauerkufen are spaced from each other.
  • the coupling mechanism further comprises a lever element, whose one end is rotatably connected to one of the pivotable adjusting elements and the other end in the direction of travel of the elevator car according to the pivoting movement of the adjusting element is movable up and down
  • the second drive device has an actuating element, which is movable up and down by a drive mechanism in the direction of travel of the elevator car and acts on the other end of the lever element of the coupling mechanism, so that the Mitauerkufen the coupling element with the car door panel open in their spaced coupling position and brought in closed cabin door leaf by moving the actuator in its approximate decoupling position can be.
  • the coupling mechanism known per se additionally has a lever element on which an actuating element of the second drive device acts such that the Mitaspiringkufen of the coupling element with the car door wing open are due to their bias in the spaced coupling position and closed cabin door leaf by moving the actuator can be brought into their approximated decoupling position and held there.
  • the actuation of the coupling mechanism between the car door leaf and shaft door leaf is effected by means of a separate drive and thus safer and more reliable than in the case of a common drive for moving the car door leaf and actuation of the coupling mechanism.
  • the second drive device for the coupling mechanism and its operative connection to the coupling mechanism are very simple and compact. In particular, the connection between the second drive device and the coupling mechanism is realized by simple mechanical components.
  • the second drive device is fastened to a door carrier fastened to the elevator car for suspending the car door leaves.
  • the second drive device is thus fixedly mounted on the elevator car and not - as in some conventional systems - directly on the coupling mechanism, which moves with the car door leaf. The ease of installation and the durability of the second drive device can be significantly improved in this way.
  • the drive mechanism of the second drive device includes, for example, a crank drive, a motor spindle, a solenoid or a linear motor.

  • coupling mechanism 16 is provided with two Mit videkufen. Upon actuation of the two coupling mechanisms 16, these are each coupled with corresponding coupling elements (eg rollers) 18, 20 on the inner shaft door panels 22.1 and 22.2 of the shaft door. Subsequently, the car door sash 14 by a in Fig.1 not shown drive to open the cabin opening 10 moves, wherein the shaft door leaves 22 are moved synchronously due to their coupling with the cabin door panels 14. The closing of the car door and the shaft door and the subsequent decoupling of the two doors are carried out in the reverse order.

  • the coupling mechanism 16 provided on the car door is always in its narrow decoupling position, so that the coupling mechanism 16 can be moved with the movement of the elevator car 12 between the respective coupling members 18, 20 on the hoistway door panels. Only when the elevator car 12 is stopped on a floor and the coupling mechanisms 16 of the car door leaves 14.1, 14.2 exactly between the coupling elements 18, 20 to the corresponding landing door panels 22.1, 22.2 lie, the coupling mechanisms 16 can be operated and the doors are opened.
  • the shaft door is also unlocked.
  • the one coupling element 20 is formed on the shaft door with a transversely displaceable axis. A displacement of the axis of the coupling element 20 can then be used to control a mechanism for locking / unlocking the shaft door.
