Definitions

  • the invention is related to a clutch for coupling a car door of an elevator car with a landing door of an elevator system in accordance with the preamble of claim 1.
  • a conventional elevator system comprises two different sets of doors, i. e. car doors and landing doors.
  • each car of the elevator system includes at least one car door.
  • each landing zone of the elevator system at least one landing door is installed.
  • Each landing door is located such that, when the car is stopped within the corresponding landing zone, the landing door is adjacent to a car door so that the interior of the elevator is accessible through the landing door and the car door provided that both doors are open. Under normal conditions, the landing doors are kept closed whenever the car is not present in the related landing zones.
  • a particular landing door can be coupled with the car door by means of a clutch which is arranged at the car door.
  • the elevator car is moved into the landing zone corresponding to that landing door and stopped.
  • the car door is mechanically coupled with the landing door by means of the clutch when the car enters the landing zone.
  • the landing door and the car door can be opened or closed by means of an actuator that is linked to the car door.
  • the clutch Prior to moving the car to another landing door, the clutch is released, thereby uncoupling the car door and the landing door.
  • the clutch is arranged at the car door and comprises at least one coupling element, which is movable with respect to the car door between a first position and a second position such that the coupling element engages with the landing door, when the elevator car is within a landing zone and the coupling element is moved towards the second position, thereby establishing the coupling of the car door with the landing door.
  • the coupling element is moved towards the first position.
  • the clutch is linked to the actuator which drives the car door.
  • the coupling element of the clutch and the car door are simultaneously driven by means of a single actuator.
  • two actuators are provided, one of said actuators being dedicated for driving the clutch and the other actuator being dedicated for driving the car door. The latter concept is advantageous in that it allows more freedom in the timing and synchronization of movement of the coupling element since the actuation of the clutch is independent of the actuator which drives the car door.
  • a clutch for coupling a car door of an elevator car with a landing door of an elevator system is disclosed.
  • the car door is movable with respect to the elevator car by means of a first actuator.
  • the clutch comprises a coupling element and a second actuator.
  • the coupling element is movable with respect to the car door between a first position and a second position by means of a second actuator such that the coupling element engages with the landing door, when the elevator car is within a landing zone and the coupling element is moved towards the second position, thereby establishing the coupling of the car door with the landing door.
  • the coupling element consists of two vanes which are connected by means of a movable linkage.
  • the vanes are movable with respect to each other for establishing a mechanical contact of the vanes with rollers, which rotate about horizontal axles disposed at the top of the landing door, and which provide rotationally stiff coupling.
  • a solenoid acting on an armature against the bias of a spring is used as second actuator.
  • the armature is arranged in parallel with respect to the vanes and in a sliding contact with one of the vanes. By activating the solenoid, the armature can be moved, thereby causing a movement of the vanes perpendicular to the direction of movement of the armature so that the distance between the vanes is changed.
  • a clutch for coupling a car door of an elevator car with a landing door of an elevator system is disclosed, the clutch being independently driven by means of a DC motor whereas the car door is opened or closed by means of a separate actuator.
  • the force provided by the DC motor is transmitted to movable parts of the clutch by means of a gear or a screw drive. Due to friction in the gear or in the screw drive, a major part of the energy provided by the DC motor is lost. Thus, the efficiency of the clutch is reduced.
  • electric power is not available for driving the DC motor, it is difficult to operate the gear or the screw drive and, thus, it becomes difficult to actuate any component of the clutch. This is disadvantageous during the installation of the clutch in the elevator system. In the case of a power failure during operation of the elevator system, it may be necessary to manually operate the clutch. It is difficult or even impossible to exercise this task, depending on the friction in the gear or the screw drive.
  • the clutch is designed for coupling a car door of an elevator car with a landing door of an elevator system, wherein the car door is movable with respect to the elevator car by means of a first actuator.
  • the clutch comprises at least one coupling element and a second actuator.
  • the coupling element is movable with respect to the car door between a first position and a second position by means of the second actuator such that the coupling element engages with the landing door, when the elevator car is within a landing zone and the coupling element is moved towards the second position, thereby establishing the coupling of the car door with the landing door.
  • the second actuator is a linear motor.
  • linear motor designates any motor comprising a motor primary and a motor secondary, wherein the motor primary and/or the motor secondary are movable in one dimension with respect to each other under the influence of a traveling magnetic field provided by the motor primary and acting on the motor secondary.
  • the motor primary is arranged at the car door and the motor secondary is arranged for force transmission to the coupling element.
  • the motor secondary may be arranged at the car door and the motor primary may be arranged for force transmission to the coupling element.
  • the motor secondary is linked to the coupling element by means of a first pivot and the motor primary is rotatable about a second pivot being stationary with respect to the car door.
  • the motor primary may be linked to the coupling element by means of a first pivot and the motor secondary may be rotatable about a second pivot being stationary with respect to the car door.
  • the coupling element may comprise two vanes which are connected by means of a movable linkage such that the vanes are movable with respect to each other for establishing a mechanical contact of the vanes with the landing door.
  • the first pivot may be arranged at the linkage or at one of the vanes. On this basis, it is possible to establish a connection between the linear motor and the coupling element, which connection is resistant to wear and, therefore, long-lived.
  • a clutch 10 for coupling a car door of an elevator car with a landing door of an elevator system is shown.
  • the clutch 10 comprises a support 11. At support 11, all movable parts of the clutch 10 are arranged:
  • the linkage 25 comprises a first connecting element 26 and a second connecting element 27.
  • the first connecting element 26 is connected with support 11 pivotally about a pivot 26'.
  • the first connecting element 26 is connected with the vanes 21 and 22 pivotally about pivots 26" and 26"', respectively.
  • the second connecting element 27 is connected with support 11 pivotally about a pivot 27'.
  • the second connecting element 27 is connected with the vanes 21 and 22 pivotally about pivots 27" and 27"', respectively.
  • the linkage 25 is arranged such that the vanes 21 and 22 and the connecting elements 26 and 27 form a parallelogram.
  • the connecting elements 26 and 27 can synchronously rotate about the pivots 26' and 27', respectively, thereby keeping the vanes 21 and 22 in parallel and changing the distance between the vanes 21 and 22.
  • the lever 28 is rigidly coupled to the connecting element 27.
  • pivots 26', 26", 26"', 27'. 27", 27"', 45 and 46 are arranged in parallel. All pivots may be provided with a wear resistant bearing.
  • the linear motor 40 can be actuated, thus leading to a linear movement of the motor secondary 42 with respect to the motor primary 41, as indicated by an arrow 47 in Fig. 2. Since the motor secondary 42 is connected with the lever 28 at the first pivot 45, the connecting elements 26 and 27 can be turned around the pivots 26' and 27', respectively, by actuating the linear motor 40. In addition, since the motor primary 41 is pivotally connected with the support 11, the motor primary 41 is turned around the pivot 46 upon an actuation of the linear motor 40, as indicated by an arrow 48 in Fig. 2.
  • the support 11 is provided with holes 12. Fastening means 13 may be passed through these holes in order to fix the clutch 20 at a car door.
