Problems solved by technology
[0008] exist Image 6 In the conventional boarding point door device shown, it is difficult to completely prevent a person (another person) who is not permitted to unlock the locking device 4 from performing the unlocking operation of the unlocking device 5
That is, another person may insert a part similar to the shape of the private key 7 into the unlocking hole 1a, or see the maintenance personnel etc. performing the unlocking operation and make others understand the unlocking method, etc., which may occur due to mischief. Locking device 4 is unlocked
[0009] In addition, in the technology described in Patent Document 1, it is intended to make others aware of the danger of opening the landing door by making the steps of the unlocking operation complicated, but when making others understand the steps of the unlocking operation, it is impossible to prevent mischief. Unlocking of locking devices caused by etc.
[0010] In addition, the technology of Patent Document 2 unlocks the locking device 4 electrically so that no special key is needed, but if the on / off state of the manual switch installed in the car and the machine room, and the position of the car If the on / off state of the landing button on the specified floor does not meet the conditions, the locking device cannot be unlocked, so it is difficult to quickly open the landing door on any floor

A landing door device of an elevator capable of securely and easily preventing the locking device of a landing door from being unlocked by the persons other than those who are allowed to unlock it. The landing door device comprises the locking device locking the landing door of the elevator, an unlocking device unlocking the locking device, an authentication device authenticating the persons who are allowed to unlock the locking device, and an unlocking limiting device allowing the unlocking operation of the unlocking device based on the results of authentication by the authentication device. When a person who is to be authenticated is authenticated, by the authentication device, to be a pre-registered person who is allowed to unlock the locking device, the unlocking operation limitation of the unlocking device by the unlocking limiting device is released, and when the person who is to be authenticated is not authenticated, by the authentication device, to be the person who is allowed to unlock the locking device, the unlocking operation limitation of the unlocking device by the unlocking limiting device is maintained.
Description
technical field [0001] The invention relates to a landing door device arranged on an elevator landing. Background technique [0002] The doors of the elevator are composed of a landing door that blocks the entrance and exit of the elevator landing of the building, and a car door that blocks the entrance and exit of the car that moves up and down in the hoistway. These two doors are generally opened and closed by a door opening and closing device provided in the car. That is, when the elevator car stops at a landing on a specified floor, the engaging units respectively provided on the car door and the landing door engage with each other, and the driving force of the door opening and closing device is transmitted to the landing via the car door. Door. That is, the landing door and the car door are opened and closed in conjunction with each other. In addition, the landing door of the landing where no car is stopped is always closed, and in order to prevent it from being acci...
