Definitions

  • the invention relates to a door drive device for opening and closing corresponding elevator door wings of elevator doors of an elevator according to the preamble of claim 1.
  • EP 0 332 841 B1 describes a door drive device for opening and closing corresponding elevator door wings of elevator doors of an elevator.
  • One elevator door leaf is designed as a car door leaf of a car door and the other elevator door leaf is designed as a shaft door leaf of a shaft door.
  • the door drive device has a first driver, which acts on a first coupling element arranged on the shaft door leaf to open a shaft door leaf, and a second driver, which is used to close it of the shaft door leaf acts on a second coupling element arranged on the shaft door leaf.
  • the first driver and the second driver can be displaced in an opening direction and a closing direction of the elevator door by means of a drive unit.
  • the two drivers in the form of driver runners are part of a coupling mechanism and their distance from one another can be adjusted by a parallelogram guide with two adjusting elements that can each be pivoted about a pivot axis.
  • the two driving skids can thus assume a non-spread position and a spread position. In the non-spread position, the two driver runners can be passed between two coupling elements of a shaft door wing, so that the elevator car can move past a floor and thus past a shaft door.
  • the two driver runners lie between the two coupling elements arranged next to one another on the shaft door leaf and can be brought laterally towards them (spread) in order to unlock the shaft door leaf on the one hand and, on the other hand, to ensure that the opening and closing movements of the car door leaf are free of play and to be transmitted synchronously to the shaft door leaf.
  • the two driving skids are thus brought from their non-spread position into their spread position.
  • the distance adjustment between the two driver runners is carried out by a door drive unit attached to a cabin door frame via a linearly acting drive means (e.g. a belt drive), which also controls the opening and closing movements of the cabin door wing.
  • the coupling elements on the shaft door leaves of the different floors must be aligned very precisely and in particular symmetrically with respect to the driver runners.
  • the distance of all coupling elements in the opening or closing direction from the driving skids in their non-spread position must be in a precisely specified range of, for example, +/- mm.
  • first locking of the elevator shaft door may be actuated independently of the coupling elements, for example with an actuator or an electromagnet, and thus locked and unlocked.
  • the first elevator door is designed as a shaft door and the second elevator door is designed as a car door.
  • the door drive device is thus arranged on the elevator car, in particular on the frame of the car door, and is displaced between the floors together with the elevator car. This means that only one door drive device is necessary, as this can be moved with the elevator car to the various shaft doors and these can thus be opened and closed.
  • the first elevator door it is also possible for the first elevator door to be designed as a car door and the second elevator door as a shaft door.
  • the door drive device is arranged on a shaft door, in particular on the frame of a shaft door.
  • FIG. 1 shows a car door of an elevator car of an elevator with a door drive device, with a car door wing of the car door being closed,
  • Fig. 2 shows the cabin door from Fig. 1 with the cabin door leaf partially open
  • FIG. 3 shows a second exemplary embodiment of a car door of an elevator car of an elevator with a door drive device
  • FIG. 1 and 2 show schematically a door drive device 12 for a side-opening single-leaf door attached to an elevator car 10 of an elevator (not shown).
  • the elevator car 10 has a door opening 14, which can be closed by a car door leaf 16 of a car door 17.
  • the door drive device 12 is arranged on a door support 18 attached to the elevator car 10.
  • the car door leaf 16 is attached to a hanging carriage 20, which can be moved horizontally along a guide rail 22 fixed to the door support 18 and can be moved by a drive unit 24 between a door leaf closed position and a door leaf open position.
  • the second rotor 40 and the third rotor 46 and thus the first driver 42 and the second driver 48 can be moved independently of one another along the stator 26.
  • the first driver 42 and the second driver 48 are aligned parallel to a displacement direction 51 of the elevator car 10 and thus perpendicular to the horizontally extending opening direction 32 and closing direction 34.
  • the elongated shape makes it possible to begin opening the shaft door wing 37 before the elevator car 10 has reached its final position on a floor.
  • Fig. 1 the car door leaf 16 and the corresponding shaft door leaf 37 are completely closed.
  • the two drivers 42 and 48 are positioned so that they can be passed between the two coupling elements 36 and 38 in the direction of displacement 51 of the elevator car 10. This allows the elevator car 10 to be moved past a floor and thus past a shaft door with a shaft door leaf without there being any contact between the door drive device 12 and the shaft door leaf.
  • the car door leaf 16 and the corresponding shaft door leaf 37 can be opened.
  • the first driver 42 and the first coupling element 36 are arranged relative to one another in such a way that as soon as the elevator car 10 is at or shortly before its final position on a floor, the first driver 42 can act on the first coupling element 36 in such a way that via the first driver 42 the shaft door wing 37 can be displaced in the opening direction 32.
  • the first driver 42 then rests on the first coupling element 36 as shown in FIG shown, in which the cabin door wing 16 and the corresponding shaft door wing 37 are partially opened.
  • a first lock of the shaft door leaf, not shown in FIGS. 1 and 2, and a second lock of the car door leaf 16, also not shown, are opened by means of an actuator.
  • FIG. 4 shows a mechanically operated first lock for a shaft door leaf of a shaft door.
  • the first lock 260 is arranged on a shaft door wing, not shown in FIG. In the position of the first bolt 264 shown in FIG. 4, in which it engages in the first recess 266, the shaft door leaf cannot be displaced in the opening direction 32, which means that the shaft door leaf is locked.
  • the first latch 264 has a first, vertically oriented rod 270 with a
  • the lever 272 is about a second pivot axis 274 arranged pivotably and has at its end facing away from the first rod 270 a first coupling element 236, which is designed analogously to the first coupling elements 36, 136 of FIGS. 1, 2 and 3.
  • the first coupling element 236 is arranged above the second pivot axis 274, so that when the first driver 242 is displaced in the opening direction 32, the lever 272 is initially tilted slightly downwards together with the first coupling element 236 and is only then displaced in the opening direction 32. The first coupling element 236 is thus initially displaced downwards in a first unlocking direction.
  • This displacement leads to a displacement of the first rod 270 upwards and thus to a pivoting of the first latch 264 about the first pivot axis 262.
  • the first latch 264 thus pivots out of the first recess 266 and the first lock 260 is unlocked. This means that the shaft door leaf can be moved in the opening direction 32.
  • the lever 272 wants to turn back into the position shown in FIG. 4 due to its weight distribution. This is possible when the shaft door leaf is closed again and the first latch 264 can engage in the first recess 266 again.
  • the immersion is additionally supported by the weight distribution of the first bar 264.
  • FIG. 5 shows a mechanically operated second lock for a car door leaf of a car door.
  • the second lock 360 is arranged on a cabin door leaf, not shown in FIG. In the position of the second latch 364 shown in FIG. 5, in which it engages in the second recess 366, the cabin door leaf cannot be displaced in the opening direction 32, whereby the cabin door leaf is locked.
  • the contact element 376 As soon as the contact element 376 is no longer pressed against the first or third coupling element 336, 341 via the base element 380, the contact element 376 wants to return to the position shown in FIG. 5 due to its weight. This is possible when the cabin door leaf is closed again and the second latch 364 can engage in the second recess 366 again. The immersion is additionally supported by the weight distribution of the second bar 364.
