Definitions

  • the present invention relates to a door drive device with a locking mechanism for lifts, in which a cabin door which can be positively connected to a shaft door by a coupling mechanism can be moved by a drive in the area of the floors, the coupling mechanism comprising a driver parallelogram mounted on a cabin door wing and two arranged on each shaft door Coupling rollers exist and the drive has a drive motor arranged above the cabin, a countershaft and a drive means which is connected to the cabin door by an actuating lever and fixes the cabin door in the closed and in the open position and the locking mechanism pivots a monitored by a safety contact Has mounted, lockable at a stop car door latch, which locks in a stop position by its own weight and by a Steuerr olle can be pressed into a release position.
  • Such a door drive device has become known from CH-PS 663 406, in which the shaft door is moved together through the car door of an elevator car located in the area of a floor.
  • a driver parallelogram mounted on the cabin door which can be driven through two drivers arranged on the shaft door, the two doors are positively coupled to one another.
  • a pivoted bolt is arranged on the cabin door, which is locked by its own weight to a stop arranged on the cabin.
  • the bolt is arranged by the running up of an angle lever connected to the bolt in an articulated manner unlocked the first control roller on a control cam arranged on each floor, the coupled doors being opened and closed automatically by the door drive device in normal operation.
  • the cabin door outside the floors remains locked.
  • the driver parallelogram is pulled apart by the force of a tension spring, with the help of a double lever and a second control roller on the one hand guiding the door drive from a dead center position and on the other hand locking the cabin door by the impact of the first control roller on the control cam arranged on each shaft door and the associated movement of the bell crank and the articulated bolt is unlocked.
  • the cabin door and the coupled shaft door can be opened by hand.
  • a disadvantage of this device is that a control curve is required for unlocking the cabin door lock on each floor, which cam must cooperate precisely with the drive device arranged on the cabin on each floor and therefore requires precise and complex regulation work on the construction site.
  • Another disadvantage is that the driver parallelogram can be compressed in the open position by external forces or inertial forces, which causes disturbing noises.
  • the invention is based on the object of proposing a door drive device in which no control cams for unlocking the cabin door lock are to be arranged on the individual shaft doors and in which the open driver parallelogram cannot be compressed by external forces or by inertial forces.
  • the advantages achieved by the invention are essentially to be seen in the fact that a single actuation curve arranged on the movable curve of the driver parallelogram and a control roller arranged directly on the car door latch are sufficient to unlock the car door latch in the area of a floor, while they unlock the car door lock outside the floors do not affect.
  • Another advantage lies in the fact that the exact spreading dimension of the driver parallelogram required for a proper function of the driver parallelogram can be adjusted by the fact that the pivoting angle of the actuating lever which can be pivoted between two fixed elastic stops is adjustable by means of two parts of the actuating lever which can be displaced relative to one another. With these arrangements, it is already possible to set the exact mode of operation of the driver parallelogram during factory assembly.
  • Another advantage lies in the fact that when the car door lock is unlocked, the driver parallelogram tilts after a minimal opening of the car and shaft doors by a pawl carried by a support roller arranged on the car in a rest position by the force of a torsion spring and in the open state with the adjusted spreading dimension is blocked.
  • the actuating elements of the locks are also arranged so that no jamming is possible, even if the cabin position is inaccurate.
  • 1 and 2, 1 denotes a driver parallelogram for a clutch mechanism between a car door 30 and a shaft door 43 of a door drive device of an elevator system.
  • the driver parallelogram 1 is arranged on the upper part of the cabin door 30 and connected to a band-shaped drive means 42 by a clamping element 19.
  • the band-shaped drive means 42 is part of a drive 36 of the door drive device, which consists of a drive motor 37, a countershaft 38, a drive belt 39 and two rollers.
  • the drive 36 is at one above the door opening on the roof of a cabin 33 arranged sheet metal carrier 34 constructed, at the ends of a fixed drive roller 40 and a tensionable deflection roller 41 are rotatably mounted, which receive the band-shaped drive means 42 with the required tension.
  • the same clamping element 19 of the driver parallelogram 1 can be clamped either on the upper run 42.1 or on the lower run 42.2 of the band-shaped drive means 42.
  • the clamping element is articulated to an actuating lever 9 and a tab 18 of the driver parallelogram 1.
  • a guide support 35 is fastened under the sheet metal support 34, in which support 31 and guide rollers 32 of the car door 30, which are rotatably mounted on the upper part of the car door 30, are guided.
  • the cabin door 30 and the shaft door 43 are shown in the present example as a central opening telescope door with the cabin door leaves 30.1, 30.2, 30.3, 30.4 and the shaft door leaves 43.1, 43.2, 43.3, 43.4.
  • a fixed coupling roller 44 and a movable coupling roller 45 are arranged on the shaft door 43 to transmit the door movement from the cabin door to the shaft door.
  • the movable coupling roller 45 also serves to unlock or lock the shaft door 43, a safety contact (not shown) also monitoring the locking electrically.
  • the driver parallelogram is again designated by 1.
  • the entrained parallelogram 1 consists of a rigid curve 2 and a movable curve 3, which are connected in an articulated and parallel pivotable manner to a fixed base plate 10 by a lower lever 7 and an upper lever 8.

  • the open position of the driver parallelogram 1 is limited by a stop 16 arranged on the base plate 10, the closed position by a stop 17 also arranged on the base plate 10.
  • the exact swivel angle for reaching the prescribed opening width of the driver parallelogram can be adjusted by slightly moving the actuating lever 9 on the upper lever 8.
  • a cabin door latch 12 is tiltably mounted, which due to its own weight and an additional compression spring 15 rests on a stop 13 arranged on the base plate 10 in a rest position. In the rest position, the car door latch 12 is locked with a stop 25 arranged on the car 33.
  • a control roller 14 is fastened to the car door latch 12, which interacts with a control curve 24 of the driver parallelogram 1 arranged on the run-up curve 5 of the movable curve 3 and unlocks the cabin door latch 12 when the driver parallelogram 1 with a fixed clutch roller 44 and a movable clutch roller 45 of a shaft door 43 is coupled.
  • the locked rest position of the car door bolt 12 is monitored electrically by a safety contact 20.

  • the individual car door wings are guided in guides of the guide bracket 35.
  • a common drive 36 built on the sheet metal support 34 above the guide support 35 on the cabin roof, drives the two middle cabin door leaves 30.2, 30.3.
  • the drive motor 37 drives the belt-shaped drive means 42 placed over the tensionable deflection roller 41 via the drive belt 39, the countershaft 38 and the fixed drive roller 40, the driver parallelogram 1 of the left middle cabin door leaf 30.2 on its upper run 42.1 and the driver parallelogram on its lower run 42.2 1 of the right middle cabin door wing 30.3 are clamped.
  • the attachment of the driver parallelogram 1 to the belt-shaped drive means 42 and the mode of operation of this driver parallelogram 1 can be seen more clearly from FIGS. 3, 4, 5 and 6.
  • the carrier parallelogram 1 which is fixedly arranged on the upper part of the associated car door leaf 30.2, 30.3 by means of a base plate 10, has the task of keeping the car door 30 locked while driving and of unlocking and coupling the car door 30 and the shaft door 43 on a target floor, so that the shaft door 43 is opened and closed together with the car door 30 actuated by the door drive 36 and then both doors are locked again.
