Description

The invention relates to a method for remotely unlocking an access door of a building with elevator according to claim 1 and a device suitable for this purpose according to claim 7 and aims to allow people from outside the building access to the building and the elevator installed therein when power outage or other disruption of the elevator, the elevator car stops between two floor holding positions and the ferry passengers can not leave this elevator car without help from outside. For such emergencies, it is already known to keep elevator-relevant systems in operation via an emergency power supply for a limited time in order to operate in the elevator car in addition to emergency lighting, a remote alarm device with intercom device for summoning the expert help.

The document JP 10218518 A describes a rescue device for an elevator installation, which allows the user of the elevator installation to recognize a service person and to grant this person access to the building. For this purpose, a device for actuating the closing mechanism of the building door and for recognizing the service person is provided. In addition, the device has communication means for communicating the user of the elevator installation with a service point and the service person.

The document JP 03128879 A describes a method of unlocking a building door to allow a service person Gets access to an elevator system that has a fault. A signal input at the building entrance by the service person is compared with a signal sent from the service center. If these two signals match, the service person gets access.

The invention is basically applicable to any elevators installed in buildings in which access to the elevator from outside the building is provided via a door, and the door is equipped with a well-known electric locking system by means of the door opening button of a remote control device electrically operated remotely. However, it offers particular benefits for elevators in non-public buildings, such as single-family homes, so-called "home lifts". If there are no other persons in the building apart from those trapped in the elevator car at the time of the malfunction, expert service personnel called in outside the building for emergency exemption can not reach the elevator if the front door is locked. The service personnel called in or called in via the remote alarming device consequently has to gain access to the building and the shut-down elevator by force or by consulting a locksmith. Both are associated with additional costs for the elevator owner and require additional time until the passenger is released from his uncomfortable situation in the seated elevator car.

According to the invention, a method with the features of independent claim 1 is given, which is characterized by a remote operation of the electric closing or locking system of the door of the elevator car. By features of claim 7, a device for remote operation of the electric locking or locking system of the elevator car is given from. Advantageous developments and refinements of the invention are indicated by the features of the dependent claims.

The invention is based on the recognition that can be eliminated by the known in building doors with electric locking and locking system equipment and type of remote control, the above shortcomings, and therefore proposes an access door of the building from the elevator car to unlock or open ,

Thus, a passenger stuck in the elevator car can release the access to the elevator for persons called in from outside the building and the emergency rescue or Evacuation of the passenger on-site at the elevator can be carried out without delay or additional effort.

Controlled access as protection against misuse of the emergency situation is achieved by allowing the device for remotely unlocking the access door from the cab only temporarily. Access to the building can thus be limited to a time interval.

In this case, the possibility of entering the building can additionally be limited to certain persons by coordinating the remote unlocking via the intercom connection. The timing and identification of the service personnel called in for help is thus guaranteed through verbal control.

In a preferred embodiment of the inventive method, the device for remote unlocking the access door is activated, d. H. connected to the emergency power supply device as soon as via the remote alarm device a voice connection to a locally separate from the building with elevator, so-called service center is constructed.

Another advantageous embodiment provides that an actuating device for unlocking the electrical closing and unlocking system is activated by the service center.

Further preferred embodiments of the novel remote release see an operation in the Elevator car installed button or by entering a specific code or by entering a key combination of the cabin elements.

The end of the activation of the device for remotely unlocking the access door is advantageously coupled to the occurrence of an event. Preferably, the actuator is deactivated again, d. H. disconnected from the emergency power supply and / or reset the alarm mode when a predetermined period of time has expired or a response of the electrical closing and locking system is made to the elevator control or is registered by the elevator control, a change in the position of the car.

An advantageous embodiment of the inventive device for remote operation of an access door of a building with elevator is that it is completely integrated in the car control panel. Actuator and lift control can be installed completely in the cab panel pre-assembled in the cabin. On the one hand simplifies the power supply of the inventive device by the emergency power supply device on the other hand expresses positive by little additional effort in the total cost.

A further advantageous embodiment provides a decentralized arrangement of the device for remote operation. An actuating device is integrated in the car control panel, while the elevator control is arranged at any point outside the cabin assembly, eg in the shaft or on the floors. Actuator and elevator control communicate via an elevator data bus with each other, which is already available for data transmission between the car control panel and the elevator control anyway. The elevator control releases the unlocking signal to the locking and closing mechanism and optionally receives feedback from it.

Fig. 1 shows a dashed line shown house 1 with a door 2, via which an access from outside the house 1 to a lift 3 installed therein is possible. The elevator 3 comprises a cable drive 4 with a motor 5, which acts on a traction sheave 6, which drives suspension cables 7, on the one hand an elevator car 3 on the other hand a balance weight (not shown) wear and raise and lower in a hoistway 9. The door 2 of the house 1 is equipped with a well-known electric locking or locking system 10.

Fig. 1 shows the elevator 3 in the event of a malfunction, in this case a power failure, as a result of which the elevator car 8 in the elevator shaft 9 is shut down in a position between the door zones 11, 11 'of two floors F1, F2. In the elevator car 8 is a passenger 12, this only leave with the help of outside. For such an emergency, the elevator car 8 is equipped with emergency devices, such as an emergency light 22 and a remote alarm 13 with intercom 14, etc., which are fed together with the electric closing and locking system 10 of the door 2 from an emergency power supply (not shown). With the remote alarm device 13 with intercom 14 known to be by pressing an alarm buttons 15, eg wired or via radio, eg via a telephone network 16 an emergency or an emergency signal to a service center 17 of the elevator operator are sold to summon expert service personnel for emergency exemption , The intercom 14 may also be provided for the transmission of video signals, so that when operated in an emergency mutual video and audio communication between the passenger 12 in the elevator car 8 and the service center 17 is possible.

Fig. 2 schematically shows a so-called decentralized structure of an embodiment of the inventive device for remote operation of a Verrieglungs- or closing mechanism 10 of a door 2. The actuator, ie according to the in Fig. 1 illustrated embodiment, the actuating button 19, and the remote alarm device 13 with intercom 14 are arranged together with a power-feeding emergency power supply system 23 in the elevator car 8. The elevator control 20 is locally separate therefrom, for example, mounted in the hoistway 9 in proximity to the cable drive 4. The actuating device and the remote alarm device 13 communicate with each other, for example, via the cabin bus. The elevator controller 20 is with the electrical closing and locking system 10 of the door 2 operatively connected; on the one hand it actuates the closing and locking system 10 and on the other hand receives a feedback signal 24 when the closing and locking system 10 is unlocked.

An embodiment with so-called central structure is in Fig. 3 shown. Here, the actuator 191, the emergency power supply system 231 and the elevator controller 201 are housed in the elevator car 81. The actuating device 191 is directly connected to the closing and locking system 101 for activation, while the elevator control 201 receives feedback from the closing and locking system 101.

Regardless of the chosen structure of the remote release device whose operation is carried out via an installed in the cabin 8 actuator. The actuator may, as in Fig. 1 shown as a separate door opening button 19 or be represented by existing in a cab panel 21 donor elements, in the latter embodiment, the remote control of the closing and unlocking system 10 of the door 2 by entering a specific code or a specific combination of keys donor elements of the car panel 21 can take place.

• Fällt während einer Transportfahrt, beispielweise die Energieversorgung des Aufzugs 3 aus, wird der Antrieb 3 festgesetzt und die Aufzugkabine 8 steht in ihrer momentanen, in Fig. 1 dargestellten Position im Aufzugschacht 9 bzw. im Haus 1 still. Sofort mit dem Stromausfall schaltet sich die Notstromversorgungseinrichtung 23 bzw. 231 selbsttätig zu und hält Notfalleinrichtungen betriebsbereit.

The method and the apparatus for the remote unlocking of a door 2 of a building 1 with elevator 3 shown so far works as follows:

• If, during a transport journey, for example, the power supply of the elevator 3 fails, the drive 3 fixed and the elevator car 8 is in its current, in Fig. 1 shown position in the elevator shaft 9 or in the house 1 still. Immediately with the power failure, the emergency power supply device 23 or 231 automatically turns on and keeps emergency devices ready for operation.

The stuck in the elevator car 8 passenger 12 actuates the alarm button 15 of the remote alarm device 13, whereupon the latter one hand, outputs a signal to the elevator controller 20 and this switches to the alarm mode on the other hand establishes a telephone connection 16 between the elevator car 8 and the service center 17, on the the passenger 12 by means of intercom 14 draws attention to his emergency situation.

In the service center 17, the alarm call is answered, whereupon expert service personnel 18 is sent to emergency shutdown to the immobilized elevator 3 and the trapped passenger 12 is informed that assistance is traveling to him. Arrived on-site at the relevant house 1, the service personnel 18 stands in front of a locked door 2 and initially has no access to the elevator 3. Therefore, the service personnel 18 makes e.g. via a mobile phone 25 to the service center 17 message. After this verbal access authorization, the service center 17, in turn, now requests the trapped passenger 12 via the intercom 14 to press the operation button 19 of the remote control device 19, 10, 20.

Upon actuation of the alarm button 15, a switching signal to the remote control device, which is integrated here in the elevator control 20, delivered, which then, for example, a Magnetic coil 26 of the electrical closing and locking system 10 energized and unlocks the door 2.

A feedback signal, which is generated here by means of control relay 27 of the closing and locking system 10 is guided to the elevator control 20 and indicates that the locking and closing mechanism 10 is unlocked or the service personnel 18 now access to the house 2 and the Elevator installed in it has 3 and can perform emergency rescue. The feedback signal resets the elevator controller 20 back to the normal control mode from the alarm mode set upon alarm triggering.

The feedback signal, which triggers the switchover of the elevator control 20, 201 into the normal operating mode, can also be performed by a device for measuring the position of the elevator car 8, e.g. an incremental encoder 28 of the drive 5, are derived for elevator control 20,201. In such an embodiment, the alarm mode is switched back to the normal operating mode as soon as a change in the position of the elevator car 8 is registered, for example as part of the emergency release.
