Definitions

  • the invention relates to a device for taking Landing doors on lifts, one of which is driven by a door operator actuated car door of the elevator provided an electromagnet is that when the elevator car stops on one floor with one arranged on a shaft door of the elevator Coupling part interacts.
  • French Patent No. 867592 is one Device for taking a shaft door of an elevator become known, the one arranged on the cabin door has two-pole electromagnet. There is a on the landing door perpendicular to this easily slidable coupling part in shape attached to a magnetic armature. With a stop on one The electromagnet is excited on the floor occurring magnetic flux of the armature slightly against the Pole of the electromagnet is moved and moved by one Cabin door that can be operated by door drive take the landing door with you can. In another version, the magnet armature is in one in the direction of travel, on the landing door attached groove and guided by two tension springs in one Middle position held. This arrangement is intended to enable that the doors are already on a Floor can be opened in a drive-in zone.
  • the appropriately long-dimensioned magnet armature shifts here in the vertical groove of the shaft door against the force one tension spring relieving the other until that Floor level is reached. After closing the doors and The magnet armature de-excites the electromagnet Action of the two tension springs in the middle position again.
  • the electromagnet a strong one for the safe taking of the landing door Generate a magnetic field and fasten it to the cabin door be that there is only a relatively small gap between the Electromagnet and the arranged on the landing door Magnetic armature is present. This can cause it to occur dynamic tolerances, e.g. Cabin movements and static tolerances, such as Relocation of buildings when the elevator cars drive past collision between the electromagnets on one floor or a possible cover provided come to a landing door sill. These collisions can lead to Faults in elevator operation and damage to the Guide the device. Because with this device the entrainment a strong magnetic field is only achieved by frictional connection required so that when the electromagnet is excited sudden loads on the shaft doors can occur. Furthermore, because of the tolerances that occur, no optimal, constant air gap between electromagnet and Magnetic armatures are observed.
  • dynamic tolerances e.g. Cabin movements and static tolerances, such as Relocation of buildings when the elevator cars drive past collision between the electromagnets on one floor or a possible cover provided
  • the invention has for its object a device to propose the type mentioned at the beginning mentioned disadvantages are avoided.
  • the electromagnet is preferably on attached to a driver connected to the cabin door. at Activation of the drive is carried out in a vertical direction shifted towards the cabin or shaft door, until a certain air gap between the electromagnet and the coupling part attached to the shaft door has been reached, after which the electromagnet in the driver with the coupling part Intervention.
  • the advantages achieved with the invention can be seen in that the driver can be placed in a rest position may not be in the passage gap between the shaft and Car door threshold protrudes, so that collisions with the Landing door thresholds while the elevator car is moving be avoided.
  • the proposed distance measurement ensures that despite possible tolerances between the shaft and Cabin door always the same optimal air gap for the Electromagnet is reached.
  • the device according to the invention enables the closed cabin door and the one above it usually arranged door operator via the in any position unlockable landing door are freely accessible without the otherwise necessary procedures for decoupling the shaft and cabin doors perform.
  • FIG. 1 denotes an elevator car
  • the one Cabin door 2 actuated by a door drive, not shown has at its lower edge on a Cabin door sill 3 is guided.
  • a landing door 4 is on guided its lower edge on a landing door sill 5, the with one inserted into a wall 7 of an elevator shaft Door frame 6 is connected.
  • a Driver 8 arranged with one on the shaft door 4th attached coupling part 9, as below in the Functional description explained in order to take the Landing door 4 can be engaged.
  • the driver 8 and the coupling part 9, the following with reference to Figures 2 and 3 are described in more detail on the cabin or landing door 2.4 attached that they are shown in the Rest position not in a passage gap DS between Cabin door and landing door sill 3.5 protrude, the Width of the passage gap DS regardless of driver 8 and Coupling part 9 can be dimensioned.
  • the driver 8 has vertically extending Toothings 10 on both sides of one on the driver 8th attached electromagnet 11 are arranged.
  • the teeth 10 for example, a thread-like profile have, while the electromagnet 11, for example with is equipped with a U-shaped or E-shaped core.
  • Guides 12 are provided, which are fixed to a base plate 13 are connected.
  • the guides 12 consist for example of U-profiles, in which 8 attached guide rollers 14 intervene.
  • the base plate 13 via damping body 15th (for example in the form of vibrating metal) by means of screws 16 and rivet nuts 18 attached to a door stiffener 17 are connected to the cabin door 2.
  • damping body 15th for example in the form of vibrating metal

  • the cabin door 2 there are two designated 8 attached to the driver.
  • proximity switches are used, which after the capacitive detection principle work and the one signal deliver when a certain distance is reached.
  • a lever arrangement 21 for the displacement of the driver 8 consists of first and second levers 22, 23, which are in the range of upper and lower ends of the driver 8 are provided.
  • the first levers 22 are articulated via supports 24 with the Base plate 13 connected, while the second lever 23 articulated are attached to the driver 8.
  • the free ends of the levers 22, 23 are rotatably connected to one another via a hinge pin 25, the hinge pin 25 of the area of the upper and lower End of the driver 8 arranged lever 22,23 via a Connecting rod 26 are connected to each other.
  • a push rod 28 of a drive 27 rotatably mounted, the articulated with a support 29 Base plate 13 is connected.
  • the drive 27 for example, a servo motor with adjustable Have speed, the push rod 28 by a with it connected rack is linearly displaceable.
  • the coupling part 9 has a vertically extending toothing 30, which is in the form with the teeth 10 of the driver 8 matches.
  • the material of the teeth 10,30 is so coordinated that during a possible Relative movement between driver 8 and coupling part 9 only minimal friction occurs and both parts practical slide into each other without wear.
  • the toothing 30 des Coupling part 9 is in the area of the electromagnet 11 interrupted. In order for horizontal to occur To absorb tolerances between the driver 8 and coupling part 9 the coupling part 9 is wider than in the horizontal direction the driver 8. In the vertical direction, the coupling part 9 and its teeth 30 longer than the driver 8, so that even with different cabin loads and the result resulting displacement of cabin and shaft door 2.4 a secure coupling and driving of the landing door4 guaranteed is.
  • Figure 4 is with 40, for example, from two door leaves 41.42 existing cabin door designated by means of carriages 43,44 and rollers 45 are guided on a running rail 4 6.
