Definitions

  • the invention relates to an elevator door drive device for opening and closing at least one car door leaf and at least one associated shaft door leaf of a lift, as defined in the claims.
  • the invention relates to the problem of transmitting the opening and closing movement, generated by a car door drive, of at least one car door leaf to the associated landing door leaf.
  • An elevator door operator is already off WO-A-03089356 known.
  • a door drive apparatus having a coupling mechanism for coupling a car door leaf to an associated landing door wing
  • the coupling mechanism comprises two parallel to the direction of travel of the elevator car aligned Mit psychologykufen which are adjustable by a parallelogram with two pivotable about each pivot axis adjusting elements in their mutual distance. If the elevator car is correctly located on a floor level, the two Mit psychologykufen lie between two on the landing door side by side coupling elements and can be brought laterally to this (spread) to unlock the one hand the shaft door wing and on the other hand, the opening and closing movement of the car door clearance and synchronous to transfer to the cabin door wing.
  • the distance adjustment between the two Mit psychologykufen takes place by a fixed to the car door frame door drive unit via a linearly acting drive means (eg., By a belt drive), which also causes the opening and closing movements of the cabin door leaf.
  • the drive means engages via 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 coupling elements, thereby unlock the shaft door leaf and form said coupling between the car door leaf and the corresponding shaft door leaf.
  • a tension spring ensures that the spreading of the Mit constitutionalkufen takes place automatically against the resistance of the shaft door unlocking. This has the consequence that at the beginning of the door opening operation, the drive means is driven by the tension spring in the opening direction until the pivot lever is fully swung in the opening direction, and that at the end of the closing operation, d. H. when undoing the spread of the Mit preparatkufen, the drive means must work against the action of relatively strong tension spring.
  • the adjusting elements are not prematurely swung back due to acceleration forces, ie the Mit supportivekufen not spaced from the coupling elements, the pivoting back of the arranged between the drive means and one of the pivotable Versmonye pivot lever prevented by a latch lever.
  • This one has the form a mounted on the door, two-armed, horizontally extending lever. When the door leaf is in its closed position, the first arm of the ratchet lever rests on a support roller attached to the car door frame, and the second arm extends horizontally below a stop cam provided on the pivot lever, via which the drive means to the one adjustment acts.
  • the pawl lever is loaded by a torsion spring with a torque around its fulcrum so that the second arm moves upward when the first arm is no longer supported.
  • the first arm of the pawl lever is raised by the support roller, the second arm moves downwards and releases the stop cam of the pivot lever, so that the drive means the pivot lever, the adjusting element and the Mit recruitingkufen can move to the starting position, in which the Mit recruitingkufen are spaced from the coupling elements.
  • the disadvantages of this device are that the latch lever does not lock the pivoting lever and the adjusting element in both pivoting directions and not without play. This can on the one hand have the consequence that the distance between the spread Mit Anlagenkufen varies, which can have a negative effect on the unlocking of the shaft doors and the accuracy of the closing of the shaft doors This may result in their interlocking being incorrect and causing a malfunction.
  • the present invention has for its object to provide a device of the type described above, which avoids the disadvantages mentioned, d. h., In which the adjusting elements and thus the Mit Conversekufen are accurately positioned in the driving position and locked free of play in both directions.
  • a described in the prior art similar elevator door drive device comprises a coupling mechanism in which one of the Mit Conversekufen moving adjusting elements or a blocking element connected to this one radially spaced from the axis of rotation of the adjusting element Recess or a projection, such as a groove or a nose, with which a complementary shaping cooperates with a pawl to temporarily block a pivotal movement of the adjusting element in both pivoting directions and backlash.
  • the recess or the projection on the adjusting element or on the blocking element connected thereto and the komlementäre shaping on the pawl are arranged so that they Exactly engage in mutual engagement when the linearly acting drive means has brought the Mit Conversekufen to a distance before the start of a door leaf opening movement, in which they are brought in the intended manner to the at least one coupling element.
  • this position causes in addition to the correct movement of the shaft door and their proper unlocking.
  • the elevator door drive device comprises a latch stop connected to the elevator car or to an elevator shaft (eg with a hoistway door frame), on which the catch strikes at the beginning of a last path section of the door leaf closing movement.
  • the pawl is pivoted so that the blocking of the pivoting movement of the adjusting element is released by the pawl, and wherein pawl and latch stop are shaped and arranged, the relative movement between pawl stop and pawl and thus the acting on the pawl stop acting substantially in the same direction, in which the komaltungsäre formation on the pawl from the recess or from the projection on the adjustment away.
  • the adjustable latch stop is adjusted so that the length of the last path portion of the door leaf closing movement referred to in the previous section is less than 6 mm. Thanks to the precise Ausklinkmechanik the inventive device, it is possible in the door leaf closing the drive movement On the door wing transmitting swivel lever - hereinafter referred to as swivel and blocking disc - release only very shortly before reaching the absolute closed position of the door to swing back. This can be reliably ensured that the spread position of the Mitêtkufen remains intact until the shaft door leaf has reached its closed position so much that the self-acting shaft door lock can engage.
  • a further advantageous development of the invention consists in that the pawl is a pivotably mounted lever on a component connected to the car door leaf, and that the position of the point of impact of the pawl stop on the pawl between its pivot point and its point of engagement with the adjusting element is selected such that the complementary shape on the pawl, which is engaged with the recess or projection on the adjusting element, moves away from its engaged position in the course of said last path portion of the door leaf closing movement by a distance greater than that of the path section.
  • each with at least two centrally-closing door panels and two mounted on each car door coupling mechanisms are according to a particularly interesting embodiment of the invention, the pawls of both coupling mechanisms arranged by one of the ends of one between the two pawls and in the direction of movement of the two leaves displaceable double-latch stop moved away from its engaged position.
  • the elevator door drive device comprises a restraint device which allows a displacement of the closed door leaf upon initiation of a door leaf opening movement, when the adjusting element is pivoted before the start of the door leaf opening movement by the linearly acting drive means almost completely in the position in which the carrier runners are brought to the at least one coupling element.
  • the restraint device comprises a pivotable retaining pawl, which holds the door at the beginning of a door opening operation in its closed position relative to the elevator car until the adjusting element is almost completely pivoted into the position before the door leaf opening movement by the linearly acting drive means in which the carrier runners are brought to the at least one coupling element.
  • the pivotable retaining pawl has the advantage that it can be unlatched in a simple manner by a cam connected to the adjusting element.

  • the car door leaf 5 is attached to a suspension trolley 7, which is laterally displaceable along a guide rail 6 fixed to the door support and is moved by a drive unit 8 via a linear acting, revolving drive means 9 between a door leaf open position and a door leaf closed position.
  • the drive unit 8 may serve an electric motor, which drives with controlled or uncontrolled speed, via a countershaft 10 or directly coupled to a drive pulley 11 of the linearly acting drive means 9.
  • the linearly acting drive means 9 may be a toothed belt, a flat belt, a V-belt or a roller chain.
  • a base plate 13 On the trolley 7, a base plate 13 is fixed, on which a coupling mechanism 14 for transmitting the movement of the car door leaf on a shaft door associated therewith (not visible) is constructed.
  • the coupling mechanism 14 comprises two parallel to the direction of travel of the elevator car aligned Mit psychologykufen 15, which are mounted on two pivotable about a pivot axis 16 adjusting elements 17.1, 17.2 and are adjustable by pivoting these adjusting elements in their mutual distance, d.
