Definitions

  • the present invention relates to an actuating device for jointly opening and closing an elevator car door of an elevator car and an elevator shaft door of an elevator shaft opposite the elevator car door, the door levels of the elevator car door and the elevator shaft door being essentially parallel and comprising the actuating device: a first drive device which is assigned to the elevator car door and is set up to drive the elevator car door to open and close it, and a driver device which is also assigned to the elevator car door and is driven by a second drive device, the driver device being convertible between a withdrawn configuration and an extended configuration, one in the withdrawn configuration Movement of the elevator car in the elevator shaft is possible and in the extended configuration the driver device into one Opening and closing the elevator shaft door together with the elevator car door cooperates with the elevator shaft door by at least one engagement element belonging to the driver device.
  • Such an actuator is for example from the EP 0 744 373 B1 known.
  • the actuating device disclosed therein comprises a pair of driver elements which, in an operating configuration in which the elevator car is to be movable in the elevator shaft, are approximated to one another and in a configuration in which the elevator stands still opposite an elevator shaft door, parallel to one another parallel to the planes of the two Doors are removed in order to finally interact with counter-drivers which are provided on the other door.
  • the driver elements are displaced out of engagement with external parts, in particular the counter-drivers of the elevator shaft door, parallel to the door planes of the elevator car door and the elevator shaft door, in order to allow the elevator to travel in the elevator shaft.
  • the swords always remain relatively close to the elevator shaft door and in particular also protrude into the plane of the elevator shaft door in their configuration intended for the elevator to travel, so that they are guided in the direction of travel of the elevator.
  • the known actuator from the EP 0 744 373 A2 has proven itself in practice and such and similar devices are also frequently used, they are not suitable for very fast-moving elevators due to the small distances between the driver elements and the components assigned to the shaft when the elevator is in operation, since these are used for safety reasons and for damage to avoid the actuating device, larger distances must be provided.
  • the first and second drive devices of the actuating device according to the invention are set up in such a way that the transfer of the at least one engagement element from the retracted configuration into the extended configuration comprises at least section-wise travel of a distance perpendicular to the door planes.
  • the at least one engagement element is no longer displaced exclusively parallel to the door planes in order to get into and out of an engagement with the elevator shaft door, but rather is moved additionally or exclusively perpendicular to the door planes.
  • the at least one engagement element can only be moved out of the cabin door operator to its actuation dimension in a state after the elevator car has been arranged in a suitable relative position to the shaft door.
  • the actuating device according to the invention is particularly suitable for high-speed elevators and elevators with a low threshold gap dimension to be maintained, since this threshold gap dimension in particular is straight along the additional transfer direction of the at least one engagement element, and thus the distance to be maintained is achieved by the displacement of the engagement element and not more by increasing the distance between the elevator car and elevator shaft.
  • the actuating device according to the invention is also suitable for elevators which run obliquely or horizontally in sections, since the at least one engagement element can also be displaced perpendicular to the door planes from the area assigned to the elevator shaft along these possible directions of movement of the elevator car. Since, in addition to the exclusive or additional displacement of the at least one engagement element in a direction perpendicular to the door planes, in the context of the actuating device according to the invention, practically no changes need to be made to the system of the elevator doors as compared to known systems, this device is also suitable as a retrofit solution or in combination with already established components so that an inexpensive transition to the device according to the invention can be carried out.
  • the first drive device and the second drive device can be formed by a single drive device, it being possible for the driver device to be coupled to the individual drive device, for example, by means of a belt coupling.
  • devices known from the prior art in the form of mechanical sequence controls can be used here, by means of which mechanical mechanisms can be used in a single drive device to ensure that, before the elevator car door is opened, the driver device first moves from its retracted configuration into its own extended configuration is transferred and only then the actual opening process of the elevator shaft door is started together with the elevator car door.
  • mechanical mechanisms can be used in a single drive device to ensure that, before the elevator car door is opened, the driver device first moves from its retracted configuration into its own extended configuration is transferred and only then the actual opening process of the elevator shaft door is started together with the elevator car door.
  • This coordinated control like the mechanical sequence control just mentioned, could ensure that the drive devices and the driver device interact in such a way that before the elevator car door is opened, the transfer of the driver device from the withdrawn configuration to the extended configuration is first completed.
  • the transfer of the at least one engagement element in an actuating device according to the invention could only take place perpendicularly to the door planes of the elevator car door and the elevator shaft door
  • the transfer of the driver device between the retracted device could ensure the reliable engagement of the at least one engagement element with the elevator shaft door and to reduce play and the extended position further comprises shifting the at least one engagement element parallel to the door planes.
  • Devices and techniques from the prior art could be used, for example, for this component of the transfer movement of the at least one engaging element, by means of which corresponding movements of engaging elements parallel to the door planes are produced there.
  • two sword legs can be provided as engagement elements, which are set up to move from the retracted configuration to the extended configuration during a transfer Configuration in the direction of the elevator shaft door and move away from each other in order to come into contact with counter elements associated with the elevator shaft door.
  • the sword legs can comprise, in particular, vertically oriented engagement sections for engaging with the counter-elements mentioned and can be displaced parallel to the vertical direction by means of a parallelogram control.
  • the driver device could comprise a spindle drive, by means of which a rotational movement generated by the second or the individual drive device is converted into the movement of the engagement element perpendicular to the door planes.
  • This spindle drive movement perpendicular to the door planes can then also include, for example, the parallelogram shift mentioned above, if the embodiment of the engagement elements is used as a sword leg.
  • the driver device could also comprise a passive spindle or an inclined plane, by means of which a movement of the engagement elements generated by the second or the individual drive device parallel to the door planes is additionally superimposed on a movement perpendicular to the door planes.
  • the two possibilities described thus differ only in whether a movement of the at least one engagement element that was originally initiated perpendicular to the door planes is additionally converted into a movement parallel to this plane or vice versa.
  • the driver device can further comprise a locking device which is set up to fix the at least one engagement element in the extended configuration.
  • the locking device can comprise, for example, a locking lever with an integrated torsion spring, which inhibits the at least one engagement element from pivoting back when the elevator shaft door changes from an opening operation to a closing operation. This locking lever can only be released again after the door closing process has been completed, whereupon the at least one engagement element can again change from its extended configuration to its withdrawn configuration.
  • the driver device can comprise at least one elastic element, for example a helical spring, which provides a preload force in the direction of the movement of the at least one engagement element perpendicular to the door planes.
  • a mechanical relief of the transfer movement for the engaging elements can be achieved, so that the actual transfer process can be carried out with a reduced expenditure of force, which enables a smaller design of the second drive device or the individual drive devices and thus contributes to increased economy of the actuating device according to the invention .
  • the actuating device according to the invention can further comprise a control device which is set up to control the operation of the drive devices or the individual drive device.
  • this control could also be carried out by an external control device, for example a higher-level elevator control, any combinations and operational couplings of several control devices also being conceivable.
  • the actuating device can lastly be designed such that the at least one engagement element is completely retracted within the cross-section in a top view of the elevator car in a retracted configuration.
  • the present invention further relates to an elevator arrangement comprising an elevator shaft, which has an elevator shaft door at at least two positions, and an elevator car with at least one elevator car door, the elevator car having at least one actuating device for opening and closing the elevator car door and one of the elevator shaft doors together assigned.
  • the elevator shaft can run horizontally or obliquely at least in sections.
  • the actuating device according to the invention can be designed in such a way that the elevator car door and the elevator shaft door of the elevator arrangement according to the invention can be one-sided, centrally moved or horizontally and vertically moved doors.
  • FIG. 1 An embodiment of an actuating device according to the invention is now shown in a schematic front view, the actuating device as a whole being designated by reference number 10 and in this form can be assigned to an elevator car (not shown) in the region of its elevator car door.
  • the actuating device 10 comprises a single electrically operated door motor 12, which is provided to open and close both the elevator car door and elevator shaft door, not shown, and also for the transfer of the actuating device 10 described below between a retracted and an extended configuration is.
  • a toothed belt 14 is assigned to the motor 12, which is guided over rollers, but of which in Figure 1 only a single roll 16 is shown.
  • the toothed belt 14 acts on a mechanism 18 which, in a manner known per se, in the event of an intended opening movement of the elevator car door and the elevator shaft door, first of all transfers the engagement elements 20 from their retracted configuration into their extended configuration and only then causes the two doors to actually open and thus acts as a mechanical sequence control.
  • the mechanism 18 and the engagement elements 20 together form the driver device in the sense of the present application.
  • the engagement elements 20 are formed by so-called swords 20a and 20b, which in the in Figure 1 withdrawn configuration shown first once by means of the mechanism 18 and joints acting as a parallelogram are brought parallel to one another.
  • the parallelogram arrangement comprises two double joints 18d and is articulated on the elevator car door via an upper and a lower joint 18a and 18b.
  • the swords 20a and 20b furthermore each comprise sections which run perpendicular to the levels of the elevator shaft door and the elevator car door and which are intended to come into contact with corresponding counterparts for moving the elevator shaft door.
  • FIG Figure 2 This process of transferring the engaging elements 20a and 20b from their retracted to their extended position can be seen in FIG Figure 2 understand that in their picture parts a) to d) the engaging elements 20a and 20b each in front view according to Figure 1 and shows in side view as well as retracted and extended.
  • inclined planes 18c are also shown, by means of which, by engaging with counter-elements 18e permanently assigned to the double joints 18d, the displacement of the swords 20a and 20b during the transition from the representations a) and b) to representations c) and d) Figure 2 is caused. It should be noted that in the Figures 1 to 3 only one of the inclined planes 18c is shown for reasons of clarity.
  • the shift referred to can best be illustrated using the two representations Figure 3 understand that only show the area of the upper joint arrangement 18a and the associated double joint 18d in an enlarged oblique plan view.
  • the upper joint 18a pivots the parallelogram mechanism 18 by driving the motor 12 and mediated by the toothed belt 14 such that the right sword 20a is deflected to the right and down and the left sword 20b is deflected to the left and up additionally on the inclined plane 18c the counter element 18d, which ensures that the two swords 20a and 20b are displaced out of the plane of the elevator car door.
  • the guide associated with the joint 18a must allow the two legs to be displaced in this direction, for example by being telescopic or oriented in this direction.
  • FIG 4 now shows views similar to that Figure 3 an alternative embodiment in which the two swords 20a 'and 20b' are also shifted by means of a parallelogram mechanism 18 '.
  • the Figure 5 shows last a third embodiment, which differs from the variants Figure 3 and Figure 4 differs in that the helical spindles and bolts guided therein for the displacement of the swords 20a "and 20b" are not assigned to the double joints 18d ", but are directly integrated in the upper and lower joint arrangements 18a" and 18b "and thus to a certain extent themselves form a spindle drive.
