Definitions

  • the invention relates to an elevator with an elevator car, a horizontally displaceable car door leaf, a horizontally displaceable shaft door panel and a coupling device for transmitting an opening movement or a closing movement of the car door leaf on the shaft door leaf, wherein the coupling device comprises a displaceable entrainment member, which is for coupling the car door leaf with the landing door wing is brought into contact with a counter element present on the shaft door wing, the interaction of the coupling device with the counter element causing the unlocking of a car door bolt. Furthermore, a method for actuating a car door bolt is the subject of the invention.
  • the invention relates to the problem of preferably allowing an opening movement of an elevator car door leaf when the elevator car is within allowable dislocations at the level of a floor.
  • a door drive device for opening and closing cabin door leaves is an elevator car door, wherein the door drive device comprises a car door lock.
  • the door drive device is actuated by means of a crank drive and comprises two coupling devices for transmitting the opening or closing movement of the car door leaves to corresponding shaft door leaves.
  • the coupling devices each comprise two guide rails guided on the car door leaf on pivotable handlebar levers, which interact with two counter elements each on the corresponding shaft door leaves when the elevator car is at a floor level.
  • One of the pivoting levers has an extension which cooperates with a fixed to the door frame stop so that the opening of the associated car door leaf is blocked when said horizontal distance of the Mitauerschienen and thus the pivotal position of the handlebar lever is not limited by the counter-elements on the corresponding shaft door leaf.
  • the distance adjustment between the two driving skids takes place by a door drive unit fastened to the car door frame via a linearly acting drive means (for example by means of a belt drive), which also effects the closing and opening movements of the car door leaf.
  • the drive means engages over a connected to one of the adjusting elements of the parallelogram pivoting lever on the car door leaf, that by the opening movement of the linear acting Drive means the adjusting elements are pivoted before the start of a door leaf opening movement in a position in which the Mit videkufen are brought to the counter elements, thereby unlock the shaft door leaf and form said coupling between the car door leaf and the corresponding shaft door leaf.
  • EP 0332841B1 also discloses a means for unlocking the bolt of a car door latch, which is to ensure that the car door is unlocked automatically only when the car door facing a shaft door of the elevator.
  • one of the Mit supportivekufen in the region of its outer - ie the cooperating with the corresponding counter element on the landing door wing (coupling roller) - skid surface on a Tastkufe This extends parallel to Mit videkufe and is connected by means of handlebar springs so that it is spaced a few millimeters from it in the unloaded state.
  • the force exerted on the Tastkufe by a coupling process (Mit Shamsp Dahl) by the counter element contact force causes their displacement against the spring force of the control springs in the direction of Mit recruitingkufe.
  • the Tastkufe has a cam, which caused their by the counter element Displacement relative to the Mit followedkufe and thus the cabin door leaves on a mounted on this car door sill car door latch transfers and unlocks the car door sash. If a door opening command and a resulting spread of the Mit psychologykufen of the coupling mechanism, when the door of the elevator car does not face a shaft door, the Mit videkufen get as well as the Tastkufe not in contact with any of the counter elements on the shaft door leaves. The Tastkufe is therefore not moved against the Mit classmateskufe, and the cab door latch remains in its locked position. A sensor monitoring the position of the car door bolt additionally prevents the door drive motor from being switched on.
  • the illustrated coupling mechanism with Kabinenfentriegelung requires on one of the Mit supportivekufen a relative to this movable and parallel guided Tastkufe, which is associated with high material and manufacturing costs.
  • the relatively small Tastweg the Tastkufe requires a lever system with a large gear ratio to produce a sufficient Entriegelungsweg the car door latch. This requires that the coupling device and the car door unlocking device must be manufactured with high precision.
  • resulting from the large gear ratio when hitting the Tastkufe on the counter element jerky accelerations of the car door bolt that have unwanted noise result.
  • EP 1541517A1 Another device for coupling a car door leaf of an elevator car with a corresponding shaft door leaf, which device cooperates with a car door lock, is off EP 1541517A1 known. How it works corresponds largely to that of the device described above EP 0332841B1 , In contrast to the device according to EP 0332841B1 is in accordance with the device EP 1541517A1 not a Tastkufe arranged on a Mit hesitationkufe, but the function of Tastkufe is integrated into one of the Mit recruitingkufen. This is realized in that this Mit videkufe is connected via hinge pieces with the pivotable adjusting elements, which change the mutual distance of the Mit recruitingkufen by their pivotal movement.
  • EP 1541517A1 known device has substantially the same disadvantages as described above in connection with the device according to EP 1541517A1 are called.
  • the present invention is in particular the object of providing an elevator with a proper cabin door lock, which is simple and inexpensive to implement and requires less manufacturing and assembly accuracy. In addition, such a car door lock should work quietly.
  • the car door latch is in the form of a slider which is displaceable in a latch guide attached to the car door leaf and cooperates with a latch stop immovably connected to the car door structure, the car door latch having a recess allowing the car door latch and thus the car door leaf to pass the latch stop To perform opening movement when the coupling movement of the driver element has been stopped in the intended coupling position by the counter element.
  • the invention makes it possible to realize a simple and cost-effective car door lock by connecting a car door bolt directly to the driver element by means of a simple, low-precision mechanical coupling which is less demanding in terms of precision.
  • the driver element performs the coupling movement from a counter-element spaced passage position in the direction of the counter element out, wherein the car door latch (45) is positioned so that an opening movement of the car door leaf (2) is possible if the driver element (21) is stopped by the counter element (30) in a defined coupling position.
  • the entrainment element (21) performs the coupling movement from a passage position distanced from the counter element (30) in the direction of the counter element, wherein the car door latch (45) is positioned so as to block the opening movement of the car door leaf (2) ,
  • the driver element (21) during the coupling movement continues to move up to a defined coupling position. This situation occurs, for example, when an excessive vertical displacement between the car door leaf and landing door leaves is present, so that the driver element does not hit the counter element in its coupling movement.
  • the movement of the car door bolt is rigidly coupled via a lever system with the movement of the driver element.
  • the term "rigidly coupled” is to be understood here as meaning that there is a coupling between two components, which ensures that, in every possible situation, a movement of the one component in the coupling direction necessarily causes a movement of the second component in the coupling direction.
  • the coupling device comprises two adjustable in their mutual distance driver elements which cooperate with two counter-elements of a shaft door leaf to couple the car door leaf with the shaft door leaf and unlock at least one movable counter element and a shaft door lock.
  • a closed position of the car door leaf and a locking position of the car door latch are monitored by an elevator control, wherein a switching element of an electrical switch coupled to the car door latch bridges its contacts when the car door leaf is closed and at the same time the car door latch is positioned in the correct locking position.
  • Each of the coupling devices 20 attached to one of the shaft door wings comprises two driver elements 21 in the form of parallel entrainment skids, which are pivotably connected to the associated cabin door wing 2, 3 via respective upper pivot levers 22 and lower pivot levers 23, the two pivot levers 22, 23 a Parallelogram guide for the two driver elements 21 form.
  • By pivoting the two pivot levers 22, 23 each associated with a cabin door wing entrainment elements are adjustable in their mutual distance.
  • the above-described crank wheel 8 determines via a lever system shown the vertical position of the mounting plate 4 pivotally mounted pressure bar 25.
  • Fig. 2 shows the cabin door 1 described above with the cabin door panels 2, 3 in the open position.
  • This open position usually occurs temporarily when the elevator car stops at a correct level of floor landing.
  • the entrainment elements 21 of the coupling devices 20 are pressed against the counter-elements 30 present on the shaft door leaves as a result of the force of the spreading spring 27 and are distanced as far apart as the distances between the opposing elements 30 permit.
  • the crank wheel 8 has rotated by about half a turn clockwise and thereby opened via the connecting rods 12, the drive lever 15 and the intermediate lever 18, the cabin door leaves.
  • a car door latch 40 is shown at the top of the cabin door 2 in the Fig. 1 and 2 .
  • This has the task of blocking the cabin door leaf 2 in its closed position, for example, if the driver elements are in their position with minimal mutual distance, ie, when the crank wheel and the car door sash are in a position in which a ride the elevator car is allowed.
  • a blockage should also take place when at the beginning of an intended door opening operation, the driver elements 21 do not encounter counter elements 30 of a shaft door, because the elevator car is not in the area of a floor station.
  • this car door latch 40 The details of this car door latch 40 are in the Fig. 3, 3A . 4 and 4A shown in enlarged, and the operation of the car door latch is described in more detail below.
  • the Fig. 3 and 3A show the car door 1 in its closed position.
  • the car door lock 40 comprises a latch guide 41, which is fixed by means of a connecting plate 42 at the upper edge of the car door leaf 2, a in the bolt guide 41 vertically displaceable, rod-shaped cabin door latch 45 with a fürlenfinnut 46, and a stationary connected to the mounting plate 4 bolt stop 47.
  • the bolt guide 41 with the guided therein car door latch 45 and the latch stop 47 are mutually arranged so that the car door latch 45 with the Bolt stop collides 47 and thus prevents an opening movement of the cabin door leaf 2 when the car door latch 45 is not positioned in the latch guide 41, that its passage groove 46 in the opening direction with the latch stop 47 is aligned.
  • the vertical position of the car door bolt 45 is determined by the pivotal position of the driving elements 21 of the coupling devices leading pivot lever 22, 23 and thus by the position of these driver elements 21.
  • the pressure bar 25 is raised to its upper position. This happens at the beginning of a rotational movement of the crank wheel in a clockwise direction and preferably before the car door leaves 2, 3 perform a significant movement.
  • the spreading spring 27 By the action of the spreading spring 27, a rotational movement of the feeler lever 26, the pivot lever 22, 23 and the locking lever 51, which is connected to an increase in the distance - ie with a spreading movement - between two driver elements 21.
  • This spreading movement also referred to as coupling movement, is limited by the fact that the driver elements 21 come to a stop on the counter elements 30 of the shaft door wings, provided that the counter elements 30 of a shaft door leaf lie in the vertical extent of the driver elements 21 of the cabin door leaf 2.
  • This is always the case when the Elevator car is located within a permissible deviation on a floor level.
  • the car door latch 45 is positioned by the synchronous with the pivot levers pivoting locking lever 51 via the push rod 50 at a height in which the present in the car door latch passage groove 46 in the opening direction of the car door leaf with the latch stop 47 is aligned and thus by the further rotation of the crank wheel caused opening movement of the cabin door leaf 2 allows.
  • This position of the coupling device 20 and the car door lock 40 is in the 4 and 4A shown.
  • the bolt stop 47 is extended in accordance with the entire opening path of the door leaf 2, so that the car door latch 45 does not fall and can collide with the back of the bolt stop when closing the car door leaf. This measure ensures that the door leaf can also be closed if, for example, in the event of a power failure, the car door latch would fall from its non-locking position when the car door leaf is open.
  • such a coupling device with car door lock can also be realized with a configuration in which the counter elements of the shaft door leaves are arranged between the driver elements of the coupling device.
