Definitions

  • the invention relates to an elevator with a door drive device with a locking mechanism, in which a car door that can be connected to a shaft door by a coupling mechanism can be moved by a door drive in the area of the floors, the coupling mechanism consisting of a driver parallelogram mounted on a car door leaf and two coupling rollers arranged on each shaft door and the door drive has a drive motor arranged above the cabin, a countershaft and a belt-shaped drive means which is connected to the cabin door by an actuating device and which fixes the cabin door in the closed and in the open position, the locking mechanism pivoting one above the cabin Has mounted cabin door latch, which is locked in a holding position by its own weight and can be pressed into a release position by means of the actuating device.
  • EP-PS 0 164 581 has disclosed such an elevator with a door drive device with a locking mechanism, in which, for coupling the cabin door to a landing door, a driver parallelogram arranged on the cabin door cooperates with two roller journals fastened to each landing door.
  • a pawl controlled by the driver parallelogram and an angle lever holds the cabin door in a locked position, on the one hand when the driver parallelogram is closed for free passage through an uncontrolled floor and on the other hand when the driver parallelogram is fully open, for example, in the event of a power failure, outside a floor.
  • the pawl is opened when the cabin is in the area of a floor, in that a control roller arranged on the angle lever runs onto a control curve arranged on the shaft door and rotates the angle lever, the pawl being guided out of the lock.
  • This unlocking takes place on each controlled floor, or in the event of a power failure when the elevator car is located within the door opening zone of a floor.
  • the cabin door and the coupled shaft door are either opened automatically by the door operator or can be pushed open by hand.
  • the car door remains locked if the elevator car is outside the door opening zone on one floor, for example in the event of a power failure.
  • a disadvantage of this device is that a control curve for unlocking the cabin door lock is required on each floor, which has to work exactly with the drive device arranged on the cabin on each floor and therefore requires precise and complex regulation work on the construction site.
  • EP-A-0 332 841 shows the features of the preamble of claim 1.
  • the cabin door in the area of the floors can also be connected to the shaft door by a coupling mechanism, again a driver parallelogram arranged on a cabin door wing and two coupling rollers arranged on a shaft door wing working together.
  • the closed driver parallelogram travels freely between the clutch rollers of a shaft door, on a target floor it couples to the clutch rollers by opening the driver parallelogram.
  • the driver parallelogram is normally closed through the door drive device, an actuating lever pivotally connected to a band-shaped drive means of the door drive device and the driver parallelogram and pivoting back and forth between two fixedly placed elastic stops closes the driver parallelogram by a pivoting movement in the counterclockwise direction.
  • the opening of the driver parallelogram is carried out by the force of a tension spring acting on the actuating lever and on the base plate of the driver parallelogram, either when the drive motor is de-energized or when the drive motor controlled by a microprocessor is switched in the opening direction.
  • the driver parallelogram is held in a central position by the coupling rollers of the shaft door, in which a run-up curve of the driver parallelogram is compressed in parallel and a control curve arranged on the run-up curve unlocks the car door lock.
  • the driver parallelogram is locked in this central position by an additional locking device.
  • a disadvantage of this device is that a faultless and expensive control for the door drive motor is required for proper door operation, that the driver parallelogram and the car door lock are spatially arranged and that the door drive device can only be used to a limited extent if shaft heights of different heights are operated on the same elevator and that for the opening movement of the doors with the door drive device, an additional locking for the open driver parallelogram is required.
  • the invention is based on the object of proposing a door drive device in which there are no control cams for unlocking the individual shaft doors the cabin door lock are to be arranged, and which places lower quality demands on the door motor control and regulation and which does not require any additional locking for the driver parallelogram.
  • Another advantage is that the actuation of the driver parallelogram, as well as the start of the door movement by means of a control curve and a toggle lever, enable the driver parallelogram and the door to be opened and closed smoothly on the closing side.
  • the door motor control and regulation of comparatively similar door drives can thus be significantly simplified and made cheaper.
  • FIG. 1 denotes a door drive of an elevator system.
  • the door drive 1 consists of a drive motor 2 , a countershaft 3 , a drive belt 4 , a drive roller 5 , a tensionable deflection roller 6 and a belt-shaped drive means 7 .
  • the door drive 1 is constructed over a door opening 8 on a sheet metal support 9 arranged on the roof of an elevator car.
  • Guide rails 10.1, 10.2, 10.3 are also arranged on the same sheet metal support 9 , for receiving sliding carriages 11.1, 11.2, 11.3, which each carry a single door leaf 12.1, 12.2, 12.3 .
  • the first sliding carriage 11.1 is connected in an articulated manner to the band-shaped drive means 7 by means of a clamping element 13 , via a toggle lever 14 and a control cam 15 .
  • This connection is shown more clearly in FIGS. 4 and 5, on a larger scale.
  • the two other sliding carriages 11.2, 11.3 are connected to each other and to the first sliding carriage 11.1 by means of cables 16, 17 known per se for taking them along.
  • the position of a driver parallelogram 18 arranged on the first sliding carriage 11.1 and of a pivotably mounted cabin door bolt 46 , as well as a fixed and a movable coupling roller 19, 20 of the respective shaft door is shown in dash-dot lines.
  • the clamping element 13 is on a sliding guide 21 arranged on the first sliding carriage 11.1 within a of limited path.
  • the control cam 15 is also rotatably mounted on the first sliding carriage 11.1 of the first door leaf 12.1 on an axis of rotation 22 of a holding plate 23 and projects with a pivot pin 24 into a recess 25 of a holding plate 23 . It is from the door drive 1 on the band-shaped Drive means 7 held in a closed position by a tensile force 54 (FIG. 4) and pulled into an open position by a tension spring 26 (FIG. 5).
  • a roller 27 arranged on the sheet metal carrier 9 serves as a rolling roller for the contour of the control cam 15 .
  • the driver parallelogram 18 is arranged on a support plate 28 on the first sliding carriage 11.1 . It consists of two curves 29, 30 , which are connected in an articulated manner to an upper 31 and a lower lever 32 , which in turn are rotatably supported on pivot pins 33, 34 of the support plate 28 .
  • a pull rod 36 is articulated on an axis 35 , which connects the driver parallelogram 18 to the control curve 15 .
  • the pull rod 36 is equipped with a length compensation 37 and has a stop 38 for a double lever 39 and a run-up curve 40 for a support roller 41 fixedly arranged on the sheet metal support 23 .
  • the double lever 39 is articulated at one end with a pin 42 to the pull rod 36 and rests with the central pivot bearing on the axis 24 of the control cam 15 protruding into the recess 25 of the holding plate 23 .
  • the force of a tension spring 43 pulls the double lever 39 in a rest position against the stop 38 of the pull rod 36 .
  • An elastic buffer 44 is provided on the axis 24 of the control cam 15 in order to dampen the opening movement of the control cam 15 at the end of the recess 25 .
  • a pivot pin 45 is provided, on which a cabin door latch 46 is pivotally mounted.
  • an actuating tab 47 is articulated, the other end of which has an actuating roller 49 guided in a link 48 of the holding plate 23 .
  • a locking roller 50 and a contact bridge 51 are arranged on the rear part of the car door latch 46 , which cooperate with a locking curve 52 fastened to the sheet metal support 9 of the elevator car and an electrical safety contact 53 which monitors the locked position of the car door lock.
  • the device described above works as follows: 1, 2 and 3, for example, shown three-leaf telescopic sliding cabin door consists of three door leaves 12.1, 12.2, 12.3 , which are attached to three sliding carriages 11.1, 11.2, 11.3 running on parallel guide rails 10.1, 10.2, 10.3 .
  • the drive means 7 of the door drive 1 is connected to the door leaf 12.1 , which has to cover the greatest distance for opening or closing the door opening 8 .
  • the other two door leaves 12.2, 12.3 are indirectly driven by cables 16, 17 , known per se, in such a way that the middle door leaf 12.2 , 2/3 and the third door leaf 12.3 , 1/3 simultaneously travel the path of the directly driven door leaf 12.1 and, for example, when the car door is open, all three door leaves 12.1, 12.2, 12.3 simultaneously lie exactly one behind the other outside the car door opening. In the closed state, the three door leaves 12.1, 12.2, 12.3 are staggered one behind the other and cover the door opening 8 entirely.
  • the switched-on car door drive 1 acts via the band-shaped drive means 7 with the tensile force 54 on the driven door leaf 12.1 and brings the car sliding door into the two positions.
  • the function of the door drive device, the driver parallelogram and the locking mechanism are to keep the cabin door locked while the cabin is moving, to unlock and couple the cabin door and the landing door on a target floor so that the landing door opens and closes together with the cabin door operated by the door driving device and both doors again before continuing to lock.
  • the regulations must be met that in the event of a power failure, the cabin door must remain locked outside the door opening area of a floor, or in the door opening area of the floor, the cabin door and the corresponding landing door must be unlocked automatically so that both doors can be opened by an enclosed passenger by hand .
  • the cabin door is locked with the driven door leaf 12.1 , see FIGS. 1, 4, 6 and 8.
  • the tensile force 54 acting on the belt-shaped drive means 7 acts via the clamping element 13 and the toggle lever 14 , also on the control cam 15 , which, against the force of the tension spring 26 , is pressed with its contour against the roller 27 fixedly arranged on the sheet metal support 9 .
  • the pull rod 36 assumes the lowest position and presses the two curves 29, 30 of the driver parallelogram 18 into the closed position via the lower lever 32 .
  • the curves 29, 30 of the driver parallelogram 18 move away from the fixed and the movable coupling roller 19, 20 of the shaft door, the movable coupling roller 20 shifting and locking the shaft door.
  • a safety contact (not shown) monitors the locking of the landing door electrically.
  • the pivotably mounted car door latch 46 is guided with its locking roller 50 over the locking curve 52 , the car door is locked and the electrical safety contact 53 is closed by the contact bridge 51 . In this state, the elevator car is ready to continue.
  • the door drive device 1 is switched over, the tensile force 54 on the belt-shaped drive means 7 changing its direction (see FIGS. 5, 6 and 9).
  • the clamping element 13 becomes along the sliding guide 21 wherein the control cam 15 is rotated via the toggle lever 14 about the axis of rotation 22 and the contour of the cam 15 rolls on the fixed plate on the carrier 9 roller 27 pulled in inside direction.
  • the contour of the control cam 15 is designed such that a jerk-free opening and closing of the driver parallelogram 18 and the doors on the closing side is ensured.
  • the control cam rotates until the elastic buffer 44 abuts the axis 24 projecting into the recess 25 of the holding plate 23 at the end of the recess 25 .
  • the driver parallelogram 18 opens, actuated by the pull rod 36 connected to the control cam 15 via the double lever 39 , until the two curves 29, 30 of the driver parallelogram 18 are present on the fixed and on the movable coupling roller 19, 20 of the shaft door present .
  • the movable clutch roller 20 is pushed away by a certain distance and thereby unlocks the landing door.
  • the driver parallelogram 18 assumes the middle position indicated by dash-dotted lines in which the slightly inclined pull rod 36 with the run-up curve 40 stands on the support roller 41 and the double lever 39 is pressed up against the force of the spring 43 and the double lever 39 in turn the actuating roller 49 of the car door latch 46 is pushed up.
  • the car door latch 46 is pivoted about the pivot 45 via the actuating tab 47 and the locking roller 50 is guided out of the lock.
  • the door can now be opened completely by the door operator 1 .
  • the shaft door lock and the car door lock are unlocked in the same manner as shown above, with the exception that instead of the tractive force 54 , which acts on the control curve 15 from the door drive 1 , the force of the tension spring 26 occurs, which rotates the control cam 15 , the clamping element 13 with the moves band-shaped drive means 7 in the slide guide 21 , the driver parallelogram 18 opens and unlocks the shaft door lock and the cabin door lock. A possibly enclosed passenger then has the option of opening the cabin door and the coupled landing door together by hand.
  • the driver parallelogram 18 opens to a maximum, with the pull rod 36 occupying the highest position at which the double lever 39 is pressed up about the axis 24 on the pull rod side and pressed down on the unlocking side.
  • the actuating roller 49 of the car door latch 46 is not moved and the car door lock remains locked. Any trapped passenger cannot open the cabin door by hand (see Fig. 8).
