Definitions

  • the present invention relates to a car door for closing an opening.
  • car doors are used in particular for closing access openings of an elevator car of elevator installations.
  • cabin doors can also be found in public transport such as e.g. Subways application.
  • Such a car door usually comprises at least one door panel, which is displaceable parallel to an access opening, and a safety contact strip, which is mounted in the region of a vertical Schliesskante forming end face of the door panel.
  • a safety contact strip serves in particular as a safety device which is intended to prevent trapping of passengers by a closing door panel. It is usually horizontally movable and parallel to the vertical closing edge forming end face of the door panel mounted thereon and intended to get into detectable contact with an obstacle located in the opening. A detected contact with an obstacle can be evaluated by a control device by the control device causes an interruption of the closing movement or a reversal of movement of the door panel.
  • the EP 1 918 241 A1 shows a door device for a lift.
  • the door device has a door panel with a safety contact strip, wherein the safety contact strip between a deployed position and a retracted position is movable.
  • a shifting device which shifts the safety contact strip in response to the position of the door panel in the extended position and the retracted position.
  • the GB 1 468 910 discloses a control unit for a sliding door unit.

  • the cabin door comprises at least one door panel which is displaceable parallel to the access opening and has a safety contact strip which is arranged parallel to the closing edge on this door panel in the region of the end edge of the displaceable door panel forming a closing edge.
  • the safety contact strip is horizontally movable between a retracted position and an extended position relative to the door panel horizontally displaceable, wherein it protrudes in the extended position in the closing direction on the Schliesskante.
  • This shift of the safety contact strip relative to the door panel is a function of the current position of the door panel relative to the cabin and serves to retract the safety contact during closing before its impact of the closing edge on the door frame as well as completely open door panel behind the Schliesskante.
  • a cable drive with at least one rope is provided to generate this relative movement between the safety contact strip and the door panel.
  • a door panel is to be understood as a component of a closure device embodied as a car door, which is suitable for temporarily and at least partially closing the access opening of a car, in particular an elevator car.
  • a cabin door can either comprise only the at least one displaceable door panel or several displaceable door panels which are provided and suitable for this purpose, in particular for persons temporarily to prevent access to the cabin or leaving the cabin.
  • the at least one door panel is guided parallel to the access opening displaceable on the cabin and comprises a closing edge forming an end that precedes in a closing movement in the closing direction and at the end of the closing movement preferably a door jamb of the door frame of the cabin or - in the case of centrally opening car doors - the closing edge Opposite door panel opposite.
  • closing edge is to be understood in particular the front side of a door panel, which forms the frontmost part of the door panel or all door panels which precedes in the closing direction during a closing operation. This closing edge would collide in a closing operation with an obstacle located in the access opening, if not a special device such as the inventive safety contact strip would prevent such a collision.
  • a cable drive is to be understood as a device which comprises at least one cable and is suitable for generating a relative movement between two components.
  • a force can be transmitted via the cable, which can serve at least partially to overcome resistance forces and to accelerate a component.
  • the force to be applied to the movement of a component may optionally be reduced by other means, e.g. Federstoff be supplemented.
  • generating a relative movement is thus meant, in particular, the transmission of a force which is the cause of the relative movement of a component connected to the cable drive with respect to another component.
  • a simple drive for producing the above-described relative movement can be provided.
  • the cable drive is characterized in that it can be flexibly arranged spatially, which is easily possible to apply the safety contact strip on door panels, the different Have dimensions, and where there are different obstacles between an actuator element and the safety contact strip.
  • complex linkage mechanisms for moving the safety contact strip can be avoided or replaced.
  • in addition to the advantage of simple construction also benefits in terms of lower noise and better maintainability. In particular, the cost of the displacement drive of the safety contact strip can be reduced.
  • a first end of the cable is connected to an actuator element and a second end of the cable is connected to a component of the safety contact strip.
  • an actuator element is meant a device capable of providing the required driving force for moving the safety contact strip relative to the door panel in at least one direction.
  • the actuator element comprises a driving lever connected to the door field, which is influenced in the closed position as well as in the region of the open position of the at least one door panel so that the drive lever via the rope, the safety contact strip from a position in which they over the closing edge of the door panel protrudes, moved to a position in which it does not protrude over the closing edge of the door panel.
  • the driving force for generating this relative movement of the safety contact strip with respect to the door panel can be generated, for example, by the drive lever in a suitable manner when retracting the door panel into the region of its closed position as well as into the region of its open position fixed to the door frame Press the way.
  • the opening and closing movement of the door panel is driven by a - not shown - door drive.
  • the actuator element may comprise its own force generator, which may apply a drive force to the first end of the rope, in particular in response to a control signal from a control device.
  • This driving force can transmitted through the cable to the safety contact strip and used to generate the relative movement of the safety contact strip with respect to the door panel.
  • a force generator of the actuator come here different means into consideration, such as an electric solenoid or an electric servomotor, which can apply a certain driving force on the rope depending on the current position of the door panel.

  • a rope Similar to a Bowden cable runs here a rope, for example in the form of a special wire rope or in the form of a flexible blade for tensile and compressive force transmission in a flexible, but longitudinally rigid shell whose ends are fixedly connected to the door panel.
  • This cable drive has the advantage that any spatial course of the cable arrangement can be selected, with such a pressure cable drive the flexibility and thus the flexibility of the cable arrangement is limited in comparison with a Bowden cable.
  • actuator element When using an acting in two directions actuator element can be dispensed with in a pressure cable drive to a return element.
  • a tensile and compressive forces transmitting cable drive without return element has the advantage that it does not have to overcome the restoring force of the return element and thus requires less effort with minimal noise.
  • safety contact strips are preferably replaced by light barriers, in particular light curtains or light grids.
  • safety contact strips continue to be used in particular in so-called fire-fighter lifts.
  • the safety contact strip can take over the safety function instead of the light barrier, if due to smoke in case of fire, the functionality of a light barrier is not guaranteed.
  • the safety contact strip When used in firefighting lifts, the safety contact strip is not required during normal operation.
  • a blocking device is provided which can hold the safety contact strip regardless of the cable drive in the retracted position. In this case, the function of the safety contact strip is suspended. Only in an emergency situation, in which the function of the light barrier is no longer reliable, the safety contact strip used as a means of preventing passengers trapped by the car door.
