Personal information of a dismissal licensor, such as a maintenance worker of an elevator management company, a manager of a building in which an elevator is installed, or the like is registered in advance in an authentication device (not shown). 6 is a release limiting device which enables the unlocking operation of the unlocking device 5 only when the authenticated person is authenticated as the unlocking permission based on the authentication result by this authentication device. The unlocking limiter 6 vertically holds the shielding plate 6a for closing the unlocking hole 1a formed in the landing door 1 and the shielding plate 6a based on the authentication result of the authentication device. By moving, it is comprised by the solenoid 6b which opens and closes the hole 1a for disengagement. Moreover, the said authentication apparatus is comprised, for example by the authentication apparatus of the password transmitted from personal terminals, such as a fingerprint combination apparatus attached to an elevator apparatus, a 1D card authentication apparatus, and a mobile telephone. In addition, when an elevator is installed in a collective house etc., the function of the said authentication apparatus may be installed in building management systems, such as a collective house. For example, as the authentication device, it is also possible to use an authentication system for releasing the automatic locking of the door of the common entrance.

In addition, in Example 1, although the unlocking limiter 6 comprised from the shielding plate 6a and the solenoid 6b is shown, the unlocking limiter 6 is a unlocking device 5 based on the authentication result of the authentication device. If it is provided with the function which enables and disables the unlocking operation of (), ie, the function which cancels or maintains the unlocking operation restriction of the unlocking device 5 based on the authentication result of the authentication device, it is not limited to the said structure. That is, the unlocking device 6 may have a configuration and an operation in accordance with the configurations of the locking device 4 and the unlocking device 5 of the landing door device, the unlocking method of the unlocking device 5, and the like. For example, in the case where the unlocking device 5 has the above-described configuration, a brake device for braking the operation unit 5a of the unlocking device 5 is provided as the unlocking limiting device 6, whereby Only when it is authenticated that the release permission is granted, the brake device may be released so that the release operation of the release device 5 can be performed, that is, the release operation restriction of the release device 5 may be released. In addition, the locking device 4 and the unlocking device 5 are not limited to the above configuration, and the unlocking hole 1a may not be formed in the landing door 1.

Next, the operation of the unlocking device 6 will be described.

3 is a flowchart showing the operation of the unlocking limiter 6 according to the first embodiment of the present invention. When a maintenance worker, such as an elevator management company, opens the landing door 1 at the time of regular maintenance inspection, etc., this maintenance worker first authenticates that he is a dismissal permission person by the authentication apparatus attached to the elevator apparatus ( Step S301). Here, in the case where the subject (here, the maintenance worker) is not authenticated by the authentication device as the release permitter (step S302), the release operation of the release device 5 is not permitted (step S303). The unlocking operation restriction of the unlocking device 5 by (6) is maintained. Therefore, the unlocking device 4 cannot be unlocked by the unlocking device 5 (step S304). Specifically, as shown in FIG. 2, since the unlocking hole 1a of the landing door 1 is kept closed by the shielding plate 6a, it is transferred to the unlocking hole 1a from the landing side. Even when the key 7 is inserted, the unlocking operation of the unlocking device 5 is not performed. On the other hand, when the authenticated device is authenticated as the unlocking permission person (step S305), the unlocking operation of the unlocking device 5 is permitted (step S306), and the unlocking device 5 by the unlocking device 6 is confirmed. The unlock operation restriction of) is released. Therefore, by performing predetermined operation, input, etc. with respect to the unlocking device 5, it becomes possible to unlock the correcting device 4 (step S307). Specifically, as shown in FIG. 4, the shielding plate 6a is moved upward by the solenoid 6b, and the unlocking device is inserted by inserting the dedicated key 7 from the landing side side into the unlocking hole 1a. It is possible to perform the unlocking operation of (5).

Here, in the case where the subject is authenticated as the dismissal permitter by the authentication apparatus, a time limit is provided to enable the dismantling operation of the dismantling apparatus 5, and the dismantling operation after a predetermined time elapses from authentication by the authentication apparatus is disabled. It is also possible. That is, after the predetermined time has elapsed, the unlocking operation of the unlocking device 5 is restricted by the unlocking limiting device 6 to prevent subsequent third party unlocking operations. Specifically, the shielding plate 6a moved upward by the solenoid 6b at the time of authentication of the unlocking permitter is moved downward after a predetermined time, and the unlocking hole 1a is closed.

Further, a means for detecting that the unlocking operation of the unlocking device 5 is completed is provided, and when it is detected that the unlocking operation of the unlocking device 5 is completed after authentication of the unlocking permitter, the unlocking operation of the unlocking device 5 is performed. Can be obtained by the release limiter 6, and the same effect as in the case of providing the above time limit can be obtained.

In addition, when the authentication device and the unlocking device 5 are installed in a place where the function of the authentication device is provided in the building management system, such as when the authentication device and the unlocking device 5 are separated from each other, the unlocking device after the authenticated person authenticates the unlocking permit by the authentication device. A predetermined time is required before performing the unlocking operation of (5). In this case, in order to prevent the unlocking operation of the unlocking device 5 from being performed by the third party within the predetermined time, after the authentication by the authentication device is performed, the installation position of the authentication device and the unlocking device 5 After a predetermined time has elapsed based on the distance from the installation position of the device or the time required for movement, etc., a time limit may be provided for enabling the unlocking operation of the unlocking device 5 for the first time. At this time, the state in which the unlocking operation of the unlocking device 5 is restricted by the unlocking limiter 6 after authentication by the authentication device is slightly longer than the time required for the movement from the authentication device to the unlocking device 5. By setting, it becomes possible to reliably prevent the decommissioning operation of the decommissioning device 5 from being performed by the third party until the decommissioning permission person reaches the installation place of the decommissioning device 5.

In addition, a correcting device, which is performed when authentication by the authentication device is not performed, that is, when the unlocking operation of the unlocking device 5 is restricted by the unlocking limiting device 6 in order to surely prevent mischief or the like of a third party. A sensor for detecting the unlocking operation to be unlocked (4) may be provided. In addition, the sensor is configured not only to detect that the unlocking operation of the unlocking device 5 is actually performed, but also to detect an operation of unlocking the correcting device 4. Specifically, the force acting on the shielding plate 6a is measured by a sensor, and when a predetermined or more force acts on the shielding plate 6a, it detects as a unlocking operation which tries to unlock the correcting apparatus 4.

In addition, when the sensor is installed, by providing a notification device that notifies the outside of the elevator remote management system, building management system, etc., the detection result by the sensor, to monitor the mischief by third parties, etc. from time to time It becomes possible. In addition, when the unlocking operation which tries to unlock the correcting device 4 is detected by the sensor, an alarm may be issued to the platform.

In addition, by providing a recording device for recording the authentication history of the dismissal permitter by the authentication apparatus, management of the dismissal permitter can be facilitated. In addition, in the case where the recording apparatus is provided, a transmitting apparatus for transmitting the authentication history recorded by the recording apparatus to the outside of an elevator remote monitoring system, a building management system, or the like may be provided.

According to the first embodiment of the present invention, since the unlocking operation of the unlocking device 5 cannot be performed unless the unlocking licensee is authenticated by the authenticating device, the unlocking of the correcting device 4 by the third party is assured. It is possible to simply prevent.

In addition, in case the authentication apparatus for authenticating the dismissal permitter does not operate normally, as shown in FIG. 5, for example, as shown in FIG. 5, the dissolution apparatus 5 by the dissolution limiting apparatus 6 is irrespective of the authentication result of the authentication apparatus. A releasing device for releasing the unlock operation restriction may be provided in a maintenance space such as a control panel in a machine room or a control panel mounted in a car. Moreover, when the function of the authentication apparatus is provided in the building management system, the function of the said release apparatus may be provided in the building management system similarly to an authentication apparatus.

As described above, according to the elevator door apparatus according to the present invention, the unlocking device cannot be operated unless the authenticated person is authenticated as a registered unlocking permitter by the authentication device, so that the unlocking device of the correcting device by a third party is unlocked. Can be prevented reliably, and it becomes possible to provide a safe elevator landing door apparatus.
