Description

The invention relates to a device on an elevator car to temporary coupling of a cabin door leaf with a landing door wing and for actuating a car door lock, as in Claims defined.

The invention relates to the problem of the opening movement of a Elevator cabin door leaf only if the elevator car is at the level of a floor, d. H. when the cabin door a shaft door facing the elevator.

With the patent EP 0 332 841 is a door drive device with a Coupling mechanism for coupling a cabin door leaf with a associated shaft door wing become known. Of the Coupling mechanism includes two parallel to the direction of travel of Elevator car aligned Mitnehmerkufen, by a Parallelogram with two pivotable about a pivot axis Adjustment elements are adjustable in their mutual distance. If the Elevator car is located correctly on a floor level, are the two Mitnehmerkufen between two at the landing door side by side arranged coupling elements and can laterally to this be introduced (spread), on the one hand to the landing door wing unlock and on the other hand, the opening and closing movement of the To transfer the car door free of play and synchronously to the car door leaf. The distance adjustment between the two Mitnehmerkufen takes place by a door drive unit attached to the car door frame via a linearly acting drive means (eg by means of a belt drive), which also the opening and closing movements of the cabin door leaf causes. The drive means accesses one with one of Adjustment of the parallelogram associated pivoting lever so on the cabin door wing that through the opening movement of the linear acting drive means the adjusting elements before the start of a Door leaf opening movement are pivoted to a position in the the Mitnehmerkufen are introduced to the coupling elements, characterized Unlock the shaft door leaf and the said coupling between the Cabin door leaf and the corresponding shaft door wing form.

At the end of a door-closing movement are by the Closing movement of the linearly acting drive means Swiveling the adjusting elements back into a position in which the Mitnehmerkufen are spaced from the coupling elements, so that the locking of the shaft door leaf in its locking position returns.

EP 0 332 841 also discloses a device for unlocking the Lock of a car door lock, which ensures that the Cabin door is unlocked automatically only when the elevator car is at the level of a floor, d. H. when the cabin door a shaft door facing the elevator.

For this purpose, one of the Mitnehmerkufen in the area of their outside lying, d. H. the with the corresponding coupling element on Bay door (coupling roller) cooperating, skid surface one Tastkufe on. This extends parallel to the Mitnehmerkufe and is by means of Handlebar springs so connected to this, that they are in unloaded condition A few millimeters from this is spaced. The one at Coupling process (entrainment spread) through the coupling element the contact blade exerted contact force causes their displacement against the Spring force of the handlebar springs in the direction of the Mitnehmerkufe. The scooter has a cam which caused its by the coupling element Displacement relative to the Mitnehmerkufe and thus the Cabin door leaves on a mounted on this cabin door sash Cabin door latch transfers and unlocks the cabin door wing.

If a door opening command and a resulting spread of the Mitnehmerkufen of the coupling mechanism, when the door of the Elevator car does not face a shaft door, so get the Mitnehmerkufen as well as the Tastkufe not in contact with one of Coupling elements on the shaft door wings. The Tastkufe is therefore not moved against the Mitnehmerkufe, and the cabin door latch remains in its locking position. A the position of the car door bolt Monitoring sensor additionally prevents switching on the Door drive motor.

This door drive device has some disadvantages.

The most significant disadvantage is that on one side of the Coupling mechanism two runners, namely a Mitnehmerkufe and the it must be conducted Tastkufe required. This has a high on the one hand Material and production costs result. On the other hand, it results technical disadvantages, such as precision losses and large moving Masses.

Another disadvantage is the relatively imprecise leadership of the tactile movement the Tastkufe by the handlebar springs, resulting in compensation correspondingly larger Tastweg requires.

The limited stability of the Tastkufenführung by handlebar springs at off-center force attack on the Tastkufe has additional Inaccuracies and thus a larger required Tastweg for Episode. This is the case in particular when the coupling element due to variable distance between elevator car and shaft door engages only in the lateral edge region of the Tastkufe.

However, larger Tastwege increase the bending stresses in the Handlebar springs and thus the risk of spring breaks.

The present invention is based on the object, a device to create the type described above, the disadvantages mentioned does not have.

According to the invention, the object is achieved by the in claim 1 resolved measures. Advantageous embodiments and Further developments of the invention will become apparent from the dependent claims. 2 to 9.

The advantages achieved by the invention are essentially in it see that a coupling device on the key page a Mitnehmerkufe which causes the entrainment of the coupling element and simultaneously detects the presence of a coupling element (detected) and in the presence of the coupling element the Cab door latch unlocked. The Mitnehmerkufe is about joint pieces with two adjusting elements connected, wherein the hinge pieces are formed and arranged one of the coupling elements on the Mitnehmerkufe exerted contact force a safe and accurate guided Additional movement of the joint pieces and the Mitnehmerkufe causes. With the expression "safe and precisely guided additional movement" is on the one hand meant that by the joint pieces the risk of a bar spring break is eliminated and on the other hand, that the hinge pieces the additional movement more accurate and stable lead, as by the elastic handlebar springs According to the prior art is possible.

Advantageous embodiments and further developments of the invention will be apparent the dependent claims.

According to a preferred embodiment of the inventive Device causes the opening and closing movement of the door leaf driving drive element or a separate door coupling drive the Pivoting movement of an adjusting element, wherein a synchronous Pivoting movement of the other adjusting element by a directly on corresponding lever arms of the two adjusting elements mounted Mitnehmerkufe is guaranteed. This construction allows one Parallelogrammartige, articulated storage of groping Mitnehmerkufe on the other two corresponding lever arms of the Adjusting.

For the drive of very heavy door leaves and for increased demands concerning low noise, it may be advantageous to the pivoting movement the adjustment by a separate door coupling drive, z. B. by a Spindelhubmotor or a gear motor to produce.

Conveniently, the Mitnehmerkufen with the swivel Adjusting elements connecting joint pieces at the ends corresponding lever arms of the two adjusting articulated stored and arranged so that the swivel angle between the Adjustment elements and the joint pieces executable Pivoting movements are mechanically limited.

Favorable conditions for the implementation of the contact force between Coupling element and first Mitnehmerkufe in a pivoting movement arise when the pivoting movement of the joint pieces so limited is that their by the connecting line between their bearings Defined joint piece axis at an angle of 20 ° to 60 ° to Longitudinal axis of the Mitnehmerkufen is aligned when the Adjustment elements are in the coupling position and the first Mitnehmerkufe is not burdened by a coupling element.

Preferably, the swivel angle between the Adjustment elements and the joint pieces executable Pivoting movements between 10 and 60 degrees. Depending on the length of the Joint pieces arise in this pivoting angle range for the Unlocking the latch favorable driver movements.

Advantageously, the mechanical limitation of the Pivoting angle characterized in that at least one of the joint pieces per two around the joint axis connecting them with the respective adjustment element arranged stops, which in the respective Limit positions to corresponding stops on the Impinge adjusting element.

In the preferred embodiment of the invention take existing coupling position of the adjusting elements and missing Exposure of a contact force from the coupling element to the at Mitnehmer mounted Mitnehmerkufe the hinge pieces and with entangled with them due to their weight or one Spring force a defined by one of the stops weight or spring-centered position in which none of the components of the device acts on the car door lock. This ensures that no Unlocking the car door occurs when the Mitnehmerkufen the Coupling process (entrainment spread) not with one Coupling element of the shaft door get in contact. This is the one Case, when the elevator car due to a malfunction does not arise correctly located at the level of a floor.

The adjusting elements, the joint pieces and the first Mitnehmerkufe are designed and arranged so that in existing coupling position of the Adjusting elements the articulated pieces occupy a position which causes that one of the coupling element on the articulated with them first Mitnehmerkufe acting contact force an additional movement of the Articulated pieces and the Mitnehmerkufe effected, in the course of which one of Components of the device a bolt of the car door lock unlocked.

According to a preferred embodiment of the invention unlocks the Mitnehmerkufe mounted on the articulated pieces or connected to it Unlocking the bolt of the car door lock. She has that Advantage that the position of the bolt along the relatively long Mitnehmerkufen can vary.

After an expedient embodiment of the invention, the bolt is the Cab door lock on around one connected to the cabin door sash Axis pivoting two-armed lever, the one arm with a having a locking stop cooperating hook, and which carries a roll on the other arm, over which he by the Mitnehmerkufe or an unlocking tab connected to it out of engagement with the Lock stop is moved.

This embodiment of the bolt allows the additional movement of the first Mitnehmerkufe optimally and with low friction losses in one Implement unlocking movement of the bolt.

An embodiment of the invention is described below with reference to the attached drawing (s) explained. Show it:

FIGS. 1A and 1B schematically show an elevator car 1 mounted elevator door drive device 2 for one side closing single wing door. Visible are an elevator car 1 with a Door opening 4, which can be closed by a car door leaf 5. The Elevator door drive device 2 is on one of the elevator car 1 fixed door support 3 constructed. The cabin door leaf 5 is at a Hanging trolley 7 attached, which fixed along a door carrier Guide rail 6 is laterally displaceable and by a Drive unit 8 via a linear acting, rotating drive means. 9 between a door leaf open position and a Door leaf closed position is moved. As drive unit 8 can a Serve electric motor, with regulated or uncontrolled speed, over a countershaft 10 or directly coupled to a drive pulley 11 of the linear acting drive means 9 drives. The linearly acting drive means 9 For example, a toothed belt, a flat belt, a V-belt or also be a roller chain.

On the trolley 7, a base plate 13 is mounted on the one Coupling mechanism 14 for transmitting the movement of Cabin door leaf on a this associated shaft door leaf (not visible) is constructed. The coupling mechanism 14 includes two Parallel to the direction of travel of the elevator car aligned Mitnehmerkufen 15.1, 15.2, the two pivotable about a respective pivot axis 16 Adjustment elements 17.1, 17.2 are mounted and by pivoting this Adjustment elements are adjustable in their mutual distance, d. H. a can take an unspread or a spread position.

At the landing door wings of all floor doors are two each Coupling elements 18 - here in the form of coupling rollers - available, the so far in the shaft space next to the Mitnehmerkufen 15.1, 15.2 protrude that they spread sideways (horizontally) directed forces and movements on the coupling elements 18 and the can transfer corresponding landing door wings, if the Elevator car 1 is located in the area of a floor level. The the shown cabin door panels 5 associated shaft door leaves are off For clarity, in all present figures not visible, and the coupling elements attached to the landing door wings (Coupling rollers) 18 are therefore only by means of so-called phantom lines shown.

The pivoting of the adjusting elements 17.1, 17.2, and thus the adjustment the distance between the Mitnehmerkufen 15.1, 15.2 is also done by the drive unit 8 via the linearly acting drive means 9. Das Principle of operation of the distance adjustment (spread) is related explained with Fig. 2.

Fig. 1A shows the position of the coupling mechanism 14 during a Drive the elevator car 1, d. H. at closed cabins and Shaft door wings. In this situation, the take-off skids 15.1, 15.2 their decoupling position (unspread position) in which they in the vertical direction between the shaft door wings Move side by side mounted coupling elements 18 therethrough can.

Fig. 1B shows the situation in which the elevator car 1 is at the level a floor opposite a shaft door and the Mitnehmerkufen 15.1, 15.2 were spread (coupling position), so that this in contact with the two coupling elements 18 am Schachttürflügel have arrived and in cooperation with these Coupling elements 18 a play-free coupling between the Cabin door leaves 5 and the associated shaft door leaf form. In the illustrated situation, the drive unit 8 the cabin door leaf 5 - and with this the assigned shaft door wing - already partially open.

Usually takes place at the beginning of the door opening operation by the Action of Mitnehmerkufen 15.1, 15.2 on at least one of Coupling elements 18 a not further described unlocking of the landing door leaf.

Fig. 2, 3 and 4 show on the basis of detail views the crucial Positions and thus the mode of action of the inventive Device, on the one hand the in connection with Figs. 1A and 1 B described coupling mechanism 14 and on the other hand a additional mechanism for unlocking a car door lock contains.

Fig. 2 shows the device in its initial position, in which the Cab door leaf 5 is closed and locked and the Mitnehmerkufen 15.1, 15.2 take their unspoken position, in which they face the Coupling elements 18 of the shaft doors are maximally spaced. As already mentioned, is on the car door wing 5 and bearing on the Guide rail 6 guided suspension trolley 7 a base plate 13 attached, on the coupling mechanism 14 for transmitting the movement of the Cabinet door wing on the associated door shaft door (not visible) is mounted. On the back of the base plate 13 is a latch 25th the car door lock to the bolt Bearing 25.4 pivotally mounted. In the present example, this is a two-armed lever with a Lock arm 25.1 and a Entriegelungsarm 25.2 formed. Of the Latch arm 25.1 has at its end a hook 25.3, over which the latch 25 in the locked state, the base plate 13 and thus the Cabin door leaf 5 with a locking stop 26 couples. This Lock stop 26 is fixed on the with the elevator car 1 fixed door carrier 3 fixed. On Entriegelungsarm 25.2 is a Unlocking roller 28 attached.

The pivoting movement of the bolt 25 is in both directions by means Bolt stops 30 and elastic stop buffers 31 limited and by means of a return spring 32 in the direction of the locking position biased the bolt.

The coupling mechanism 14 transmitting the opening and closing movement of the car door leaf 5 to the corresponding shaft door leaf essentially comprises the following components:

  • a first Mitnehmerkufe 15.1 and a second Mitnehmerkufe 15.2,
  • two two-armed adjusting elements 17.1, 17.2, which are fixed to a respective mounted on the base plate 13 pivot axis 16 and are pivoted by the aforementioned linear drive means 9 of the respective situation.
  • two joint pieces 20.1, 20.2, each of which form an articulated connection between in each case one arm of the two adjusting elements 17.1, 17.2 and the first driving skid 15.1,
  • one with the first Mitnehmerkufe 15.1 firmly connected Entriegelungsfahne 21, which transmits a Entriegelungsbewegung (additional movement) of the Mitnehmerkufe 15.1 mounted on a second arm 25.2 of the bolt 25 Entriegelungsrolle 28 of the car door lock.

Before beginning a door-opening operation, i. H. in the in Fig. 2 illustrated situation with closed cabin and shaft doors, exercises the linearly acting drive means 9 via the connection point 24 a to the left closing force on the adjustment 17.1 or one with This affiliate auxiliary element, which causes the on the Swivel axis 16 seated adjustment 17.1 occupies a position in which the Mitnehmerkufen 15.1, 15.2 lowest possible from each other are spaced (not spread position) and a sufficient distance have to the coupling elements 18 on the landing door wing. The second Adjustment 17.2 is on the second Mitnehmerkufe 15.2 rigid with the coupled first adjustment 15.1 and therefore always takes the same Position like the latter one. The mentioned closing force act - not here shown - attacks, one of which the unspread position the Mitnehmerkufen 15.1, 15.2 defined and a second the Closing movement of the entire coupling mechanism 14 with the Cabin door leaves 5 limited.

The first Mitnehmerkufe 15.1 is about two joint pieces 20.1, 20.2 with two corresponding arms of the two adjusting elements 17.1 and 17.2 articulated, d. h., between these two arms of the Adjustment elements does not exist a direct connection. The articulated pieces take in this situation one through the interaction of the Adjustment element stops 17.1.1, 17.2.1 with the first Joint piece stops 20.1.1 and 20.2.1 and by the weight of the Mitnehmerkufe 15.1 defined position, in which one on the Mitnehmerkufe 15.1 acting horizontal force no additional movement can cause.

At the beginning of the door leaf opening process moves on the Junction 24 coupled to the adjustment 17.1 linear acting drive means 9 to the right, so that the adjusting elements 17.1, 17.2 - supported by a spreading spring, not shown - in Start counterclockwise to turn. This will be the Mitnehmerkufen 15.1, 15.2, spread apart. As soon as the Mitnehmerkufen 15.1, 15.2 reaches its maximum spread position have, the adjusting elements 17.1, 17.2 and the Mitnehmerkufen blocked by a - not shown - mechanism, so that the force of the drive means 9 on the entire Coupling mechanism 14 and thus also on the cabin door leaves. 5 transfers.

Fig. 3 shows the situation described above, in which the Mitnehmerkufen 15.1, 15.2 are completely spread, but this not come into contact with coupling elements of the shaft door leaf are because the door opening operation due to a malfunction in a Situation has been initiated in which the elevator car is not in the Area of a floor level. The joint pieces 20.1, 20.2 are now in a position that took place through the Pivoting movement of the adjusting 17.1, 17.2 and still by the first joint piece stops 20.1.1, 20.2.1 and the Verstellelementanschläge 17.1.1, 17.2.1 is defined. In this position is the Mitnehmerkufe 15.1 due to the pivoting movement of Adjustment elements raised to a height on which the fixed to her Entriegelungsfahne 21 on the Entriegelungsarm 25.2 of the bolt 25th attached unlocking roller 28 could operate. However, since none of Coupling horizontally applied to the Mitnehmerkufe 15.1 Contact force is present, the Mitnehmerkufe and the Entriegelungsfahne 21 laterally too far from the unlocking roller 28th removed, with the result that the bolt 25 in his Locking position remains and a movement of the cabin door leaf. 5 prevented.

Fig. 4 shows the inventive device in the situation in which the Mitnehmerkufen 15.1, 15.2 in the course of the spreading process with the Coupling elements 18 come into contact, d. h., in which the Door opening operation has been initiated in a situation in which the Elevator car has been correctly located in the area of a floor level. As a result of the pivoting movement of the adjusting 17.1, 17.2 have the reached a position on these articulated joint pieces 20.1, 20.2, in which between the first Mitnehmerkufe 15.1 and the Joint pieces existing bearings so far above the Connecting joint pieces with the adjusting elements 17.1, 17.2 Bearings are that of the coupling element 18 on the Mitnehmerkufe 15.1 and the joint pieces exerted contact force F the Hinges 20.1, 20.2 counterclockwise has been able to pivot (Starting position before pivoting: Fig. 3). The way of this Pivoting movement, through which the Mitnehmerkufe 15.1 a Additional movement has been carried out by the impact of the second Hinge piece stops 20.1.2, 20.2.2 on the adjusting element stops 17.1.1, 17.2.1 limited. The named additional movement of Mitnehmerkufe 15.1 has caused that attached to this Entriegelungsfahne 21 the on Entriegelungsarm 25.2 of the bolt 25 mounted unlocking 28 has moved to the left, causing the latch 25 in the Has been pivoted counterclockwise, so that in the in Fig. 4 illustrated situation of the hook 25.3 is no longer engaged with the Latch stop 26 is located. The cabin door leaf 5 is thus unlocked, and the linear-acting drive means 9 can this in common moved with the shaft door coupled to it in its open position become.

During the subsequent door leaf closing process, this moves over the Junction 24 with the first blocked by a mechanism Adjustment 17.1 connected drive means 9 to the left. As a result of Effect of the blocking mechanism, not shown here remain during the closing movement of the door the Mitnehmerkufen 15.1, 15.2 spread and unlocked the bolt of the car door lock. Shortly before the car door leaf 5 has reached its closed position, the Effect of blocking the position of the adjusting element 17.1 Mechanism repealed, and the drive means 9 pivots the Adjustment elements and the Mitnehmerkufen in the above in Relationship with Fig. 2 described starting position back. The Mitnehmerkufen thereby remove from the coupling elements 18, and the Entriegelungsfahne connected to the first Mitnehmerkufe 15.1 21 releases the unlocking roller 28, so that the latch 25 in his Locking position returns. Not shown here Monitoring sensors on the latch 25 and the Shaft door locks signal the elevator control that the Elevator car can now move away from the door area.
