Definitions
- the present invention relates to an elevator and a method for emergency unlocking of a car door of an elevator.
- a car In an elevator, a car is typically moved vertically in a shaft between different floors or levels within a structure. The floors are intended for passengers to enter and exit the cabin or for other loads to be transported to be loaded into or unloaded from the cabin.
- shaft doors are arranged on the floor and the cabin has a cabin door for this purpose.
- the cabin door and the shaft door together form an open and closable passage from the cabin to the floor or vice versa.
- the cabin door has a cabin door lock that locks one or more cabin door leaves while driving.
- the shaft door also has a shaft door lock that keeps one or more shaft door leaves locked, at least when the cabin is away.
- the cabin door also has a drive that is designed to open and close the cabin door leaves.
- this movement of the car door leaves is transferred to the shaft door that is to be opened on the floor being approached by means of a door coupling.
- a car door coupling engages with a shaft door coupling, which together form the door coupling.
- the shaft door coupling often has at least one roller that rolls along at least one coupling guide. Alternatively, it can also be the other way around.
- the door coupling can also unlock a lock on the shaft door.
- the US 8820485 B2 shows a known door coupling, which unlocks a shaft door leaf by spreading the door coupling and the door coupling also transmits a movement of a car door to the shaft door leaves.
- the door clutch has a mechanism that uses movement of the cabin door drive to unlock the cabin door.
- EP3328769A1 shows an electric actuator for unlocking a cabin door. Such an electric drive requires electrical energy to unlock. An actuator like this does not work in the event of a power failure. In the event of a power failure, the cabin can be moved to a floor using known methods. However, the cabin door cannot be unlocked and the passengers in the cabin remain trapped.
- an elevator solves the problem.
- the elevator has a car that can be moved in a shaft and travels to at least one floor.
- the car has a car door with at least a first car door leaf and the elevator has a shaft door with at least a first shaft door leaf.
- the cabin door has an electrically activated cabin door lock and the shaft door has an electrically activated shaft door lock.
- the car door lock has a first latch for locking the first car door leaf.
- the shaft door has a lock that can be reached from the floor, through which the shaft door can be unlocked from the floor.
- the lock can be operated manually.
- the cabin door lock has an emergency release mechanism, and the emergency release mechanism is operatively connected to at least the first bolt of the cabin door lock.
- An actuator is attached to the shaft door, which can be moved from a first position to a second position by moving a key in the lock.
- the emergency unlocking mechanism can be actuated, by actuating the emergency unlocking mechanism the first bolt can be brought into an unlocked position and the cabin door lock can thereby be unlocked in order to unlock the first cabin door leaf.
- a method for emergency unlocking of a car door of an elevator solves the problem.
- the elevator has a car that can be moved in a shaft and which travels to at least one floor.
- the car has a car door with at least a first car door leaf and the elevator has a shaft door with at least a first shaft door leaf.
- the cabin door points in electrically activated cabin door lock and the shaft door has an electrically activated shaft door lock.
- the car door lock has a first latch for locking the first car door leaf and an emergency release mechanism.
- the shaft door has a lock that can be reached from the floor.
- An actuator is attached to the shaft door.
- the method includes the steps that the shaft door is unlocked from the floor by manually operating the lock, the actuator is moved from a first position to a second position by operating the lock, the emergency unlocking mechanism is carried out by the actuator when the second position is reached is operated and the cabin door lock is unlocked by operating the emergency release mechanism in order to unlock the first cabin door leaf.
- the travel path of an elevator includes the space through which the car travels during its journey to the floors. It can run inside a building or outside a building.
- the shaft doors separate the travel path from the space on the floor. This prevents people from falling.
- a service technician or another person familiar with operating the elevator, can free passengers who are trapped in the elevator thanks to the invention.
- the service technician inserts a suitable key into the lock of the shaft door to unlock the shaft door.
- the key and the lock can be designed in such a way that just inserting the key into the lock moves the actuator into the second position.
- the emergency unlocking method further comprises the following steps: a key is inserted into the lock, that the key is preferably turned by at least 20°, and that the cabin door is unlocked by the actuator activating the emergency release mechanism on the cabin door lock by turning the key.
- the key is preferably designed as a triangular key.
- the key can also be a construction key. This can be seen as an advantage because these types of keys are widely used, so many people have such a key. In an emergency, many people are able to free the passengers from the cabin.
- the shaft door is preferably unlocked via a mechanical operative connection between the lock and the shaft door lock, so that the movement of the key in the lock leads to the shaft door being unlocked.
- a mechanical operative connection between the lock and the shaft door lock, so that the movement of the key in the lock leads to the shaft door being unlocked.
- such connections are permanently existing connections, since the shaft door lock is permanently attached to the shaft door.
- Such a direct connection can be formed, for example, by means of a tension rod, a compression rod, a Bowden cable or a lever.
- the movement of the key in the lock causes the actuator attached to the shaft door to also be moved from the first position to a second position.
- the movement can, for example, be designed as a linear displacement, such as when a cylinder is extended.
- the traversing movement can alternatively be designed in an arc shape, as could be achieved, for example, by being guided by a parallelogram.
- the actuator is moved into the second position directly by the movement of the key in the lock, or by a transmission of this movement, for example by means of a push rod.
- the actuator is preferably in contact with the emergency release mechanism, thereby actuating the emergency release mechanism.
- the emergency release mechanism can have a pusher to which the actuator can apply a pressure force.
- the emergency release mechanism can have a link that can be actuated by the actuator.
- the movement of the pusher or the backdrop can be done, for example a lever, a push rod or a Bowden cable is transferred to the cabin door lock.
- the emergency release mechanism is therefore operatively connected to the first bolt of the cabin door lock.
- the door leaves can be designed, for example, as rolling doors or as folding doors.
- the door leaves are preferably part of a sliding door, i.e. designed as solid plate-like bodies that are moved horizontally, perpendicular to a doorway.
- the emergency release mechanism is designed as an emergency release lever.
- the emergency release lever can be designed as a rod or tube that is connected directly to the cabin door lock. A pressure force exerted by the actuator on the emergency release lever leads to a movement of the emergency release lever, which leads to a movement of the cabin door lock and in particular of the first bolt.
- the emergency release lever is therefore operatively connected to the first bolt of the cabin door lock. This is a cost-effective embodiment because such an elevator only has a few additional components.
- the first car door latch engages a hook of the first car door leaf, which is locked by this engagement of the latch.
- the movement of the actuator can therefore lead to a movement of the car door lock in several ways, and this movement leads to the unlocking of the car door leaf.
- the actuator bridges a distance between the shaft door and the cabin door in the second position. This allows the actuator to come into effective connection with the emergency release mechanism.
- the bridging is preferably carried out using the actuator designed as a mechanical element.
- the car door has a second car door panel which can be locked by a second latch and the emergency unlocking mechanism also brings the second latch into an unlocked position.
- the shaft door also has a second shaft door leaf.
- the method for emergency unlocking of a cabin door further comprises the step: that a second cabin door panel is unlocked by actuating the emergency unlocking mechanism.
- the elevator can therefore have a second car door panel and optionally also a second shaft door panel.
- the door leaves i.e. the cabin door leaves and/or the shaft door leaves, can move telescopically.
- the first and second cabin door panels can also move in a centrally opening manner, which means that the first cabin door panel and the second cabin door panel move away from each other in opposite directions when opening from a door gap located in the middle of the cabin door.
- the actuator is designed as a lever which is rotated in a horizontal plane by turning the key.
- the actuator can be designed as a lever, which is preferably attached directly to the shaft door lock.
- the lever can be designed as a metal strip, rod or tube. The actuator then rotates in a horizontal plane, the axis of rotation is aligned vertically.
- the method for emergency unlocking of a cabin door further comprises the following step: turning the key directly causes the actuator to rotate.
- the rotation of the actuator is a special case of traversing movement. During rotation, the actuator rotates around an axis of rotation that is fixed in space.
- the actuator and the key in the lock preferably have a common axis of rotation.
- the actuation involves applying a compressive force to the emergency release lever.
- the actuator presses on the emergency release mechanism by essentially applying a pressing force.
- the actuation can also take place via a magnetic force, for example.
- either the actuator or the emergency release mechanism has a magnet.
- the other one, from the actuator or emergency release mechanism is off made of a ferromagnetic material or has at least a part made of ferromagnetic material. The magnet then serves to attract the ferromagnetic part if a distance in the lock is reduced by operating the key, and to unlock the cabin door lock due to the increasing attraction.
- the emergency release mechanism and the actuator can both have a magnet. These magnets can be polarized in such a way that they repel each other when they approach each other by pressing the key in the lock. This repulsive force can also actuate the emergency release mechanism.
- the cabin door lock has a rotor which is rotatably mounted about an axis.
- This axis is preferably aligned horizontally.
- a horizontally aligned axis can easily be aligned vertically on the vertical cabin wall.
- the movement runs within a narrow area, which is preferably aligned parallel to the first car door leaf. Since this area is narrow, the cabin door fighter can be designed to be slim, thereby leaving more space for a cabin interior.
- the first latch and the emergency release mechanism are firmly connected to the rotor.
- the cabin door lock therefore essentially consists of a single movably mounted body. This has the advantage that there is no need for additional joints or mechanisms.
- the emergency release lever and the first bolt can optionally be combined to form a common component.
- the first bolt and the emergency release lever can be machined from a single workpiece, preferably a piece of sheet metal.
- the same component can also have a part that acts as a clamping weight or to which the clamping weight can be attached.
- the second bar can be made on the same component.
- the rotor has a pretensioner, so that the first latch is preloaded by the pretensioner towards a locked position. is exciting.
- a pretensioner can be designed, for example, as a tension spring, as a compression spring, as a torsion spring or as a tension weight.
- Fig. 1 shows an upper part of a cabin door 200 in a frontal view
- Fig. 2 same embodiment as Fig. 1 with unlocked cabin door lock 203
- Fig. 3 same embodiment as Fig. 1 in a side view
- FIG. 4 shows the same embodiment as FIG. 1 in combination with a shaft door 100 in a side view when the shaft door lock 103 is actuated
- Fig. 6 shows an elevator with the car door 200 and several shaft doors 100.
- Fig. 1 shows the cabin door 200 with a first door leaf 202, 202a slidably attached thereto and a second door leaf 202, 202b slidably attached thereto in the closed state.
- the rollers 230 serve to store the door leaves 202 on the door frame 221 so that they can be moved with little friction.
- the first door leaf 202a has a first door hook 211, on which a first latch 205 can engage in order to lock the first door leaf in the closed position.
- the second door leaf 202b similarly has a second door hook 212, on which a second latch 207 can engage in order to lock the second door leaf in the closed position.
- the first latch 205 and the second latch 207 can be rotated together as one body in a clockwise direction so that the first latch 205 releases the first car door hook 211 of the first car door leaf 202a and the second latch 207 releases the second car door hook 212 of the second car door leaf 202b.
- both door leaves 202 are free to be moved and thus opened by a door drive or by hand by a service technician.
- the movement of the car door leaves 202 is transmitted through the car door couplings 20, 220 to the shaft door couplings 120 (see FIG. 4). Normally unlocking takes place via an electric cabin door lock drive 201 (see Fig. 3 or 4).
- the cabin door lock 203 can be unlocked by an emergency release mechanism 209 of the cabin door 200.
- the emergency release mechanism 209 is designed as an emergency release lever 210.
- a pressure force i.e. the actuator force 500 (see FIG. 5) from left to right on the emergency release lever 210, the latter is rotated.
- the latches of the door lock 203 rotate, as shown in FIG. 2, and the cabin door leaves 202 are unlocked or released for movement.
- Fig. 3 shows a side view of a situation in which the car 600 stops at a floor 601 and therefore the shaft door 200 and car door 100 lie opposite one another at the same height. The roles are not shown in Fig. 3.
- the shaft door 100 and the cabin door 200 are essentially at a distance 17 from one another. The distance 17 is only undershot in the area of the door coupling 20, in which a shaft door coupling 120 engages with a cabin door coupling 220.
- the hoistway door coupling 120 and the car door coupling 220 engage with each other so that the first car door panel 202a and the first hoistway door panel 102a move together.
- a vertical movement of the cabin 600 is made possible by the shape of the shaft door coupling 120 and the cabin door coupling 220.
- the door coupling 20 causes the first landing door panel 102a to be moved on the floor 601 together with the first car door panel 202a.
- the car door leaf 202a is locked as described in FIG. 1.
- the first shaft door leaf 102a is also locked via a hook 111 of the first shaft door leaf 102a and a first shaft door latch 105.
- the car door lock 203 is driven by the electric car door lock drive 201 and can thus unlock the first car door leaf 202a.
- the landing door lock 103 is driven by the electric landing door lock drive 101, and can thus be the first car door leaf 102a unlock.
- the cabin door lock 203 is attached to the cabin door lock 221.
- the shaft lock 103 is attached to the shaft door fighter 121.
- a lock 11 and the actuator 15 are arranged in the shaft door stop 121, so that the actuator 15 is at a distance from the clearance area of the cabin in the first position. The actuator 15 is also protected from dirt or falling objects in the shaft door fighter 121.
- Fig. 4 shows the same embodiment as Figs. 1 and 3 but in a situation in which the actuator 15 is just touching the emergency release lever 210, i.e. immediately before the lock is opened.
- the first cabin door lock bolt 205 is still locked.
- Fig. 4 shows the situation in which a service technician 19 opens the shaft door 100 and a cabin door 200 behind it in order to free passengers from the cabin. To do this, the service technician 19 inserts the key 13 into the lock 11. The key can be turned in the lock 11. The rotation of the key is transmitted to the actuator, which can now bridge the distance 17 to the cabin door fighter 221 due to a long lever arm. In the cabin door fighter 221, the actuator 15 presses on the emergency release lever 210.
- the actuator 15 and the key 13 in the lock 11 have a common axis of rotation. So there is no need to translate the movement to a gear or linkage.
- Fig. 2 the movement of the cabin door lock 203 caused by the actuator 15 is shown by the rotating arrow.
- the shaft door lock 103 is also unlocked when the key 13 is turned. This can be achieved classically (not shown) via a permanent mechanical connection between the lock 11 and the shaft door lock 101. This connection can be made, for example, as a push rod that directly or indirectly connects the lock 11 with the shaft door lock 103. Alternatively, the shaft door lock 103 can also have a separate emergency release mechanism, such as a separate emergency release lever. As a result, in an emergency, the cabin door 200 and the shaft door 100 are unlocked in the same way.
- Fig. 5 shows further alternative variants for the design of the emergency release mechanism 209 and, independently of this, various design variants of a pretensioner 540.
- the cabin door lock 203, the first cabin door bolt 205, the second cabin door bolt 207, the first cabin door hook 211 and the second cabin door hooks 212 are each designed in the same way.
- an actuator force 500 always acts. This is the pressure force that the actuator 15 (see Fig. 4.) applies to the emergency release mechanism 209.
- FIG. 5a shows the use of a Bowden cable 501.
- the actuator force 500 presses on a Bowden cable lever 512.
- the Bowden cable lever 512 pulls on a pull cable 511 when actuated.
- the pull cable is in a hose 510 Cabin door lock 203 guided.
- the pull rope 511 is connected to the cabin door lock 203 such that a pulling movement on the pull rope 511 unlocks the cabin door lock 203.
- the pretensioner 540 tensions the pull cable 511, so that the emergency release mechanism 209 is moved back to the original position when the actuator force 500 is lost.
- the pretensioner 540 is shown as a tension spring 541 in FIG. 5a.
- a compression spring could also be installed. This would then have to be installed on the other side so that its power has the same effect.
- 5b shows an emergency release linkage 502.
- the actuator force 500 presses on a pusher 520, which in turn presses on a first linkage lever 521.
- the movement is transmitted to the car door lock 203 via the linkage push rod 522, a linkage angle 523 and a pull wire 524.
- pusher 520 is optional. It is also possible to apply the actuator force 500 directly to the first linkage lever 521, thereby omitting the pusher 520.
- the pretensioner 540 is designed as a torsion spring 542 in FIG. 5b.
- 5c shows an emergency release gate system 503.
- the actuator force 500 of the actuator 15 acts on a link surface 530.
- a link lever 531 is set in rotation about a link pivot point 532. This rotation sets the car door lock 203 in motion via a pull wire 533 and unlocks the car door leaves 202.
- the pretensioner 540 is designed as a clamping weight 543 in FIG. 5c.
- FIG. 6 shows a cabin 600 with a cabin door 200. This can be moved in a shaft 603 along a travel direction 602. The travel direction 602 is aligned vertically. The cabin 600 travels to several floors 601. The floors are separated from shaft 603 by shaft doors 100.
