  • a hatch door 1 for closing a hall entrance is provided on an elevator hall provided on each floor of a building.
  • the opening/closing operation of the hatch door 1 is generally performed by a door operator (not shown) provided on an elevator car (not shown).
  • the hatch door 1 is configured so that the opening/closing direction thereof is guided by rolling of hanger rollers 2 provided rotatably above the hatch door 1 on a hanger rail 3 provided on a shaft wall above the hall entrance.
  • the hatch door 1 on the elevator hall at which the car is not stopping is always closed, and is further locked by a locking device 4 provided on the shaft side to prevent the hatch door 1 from being opened inadvertently when the hatch door 1 is being closed.
  • the locking device 4 includes a first hook portion 4a fixed on the shaft wall above the hall entrance and a second hook portion 4b engaging with the first hook portion 4a when the hatch door 1 is being closed.
  • an unlocking device 5 is provided to unlock the locking device 4 by a predetermined operation or input from the elevator hall side when the hatch door 1 must be opened, for example, at the time of elevator maintenance.
  • the unlocking device 5 shown in Figure 1 is provided with an operating portion 5a below the second hook portion 4b of the locking device 4, and is configured so that the locking device 4 is unlocked by performing a predetermined operation of the operating portion 5a.
  • a person authorized to unlock the locking device 4 inserts a special-purpose key into an unlocking hole 1a formed in the hatch door 1 from the elevator hall side, and operates the operating portion 5a of the unlocking device 5 by using the special-purpose key to unlock the locking device 4.
  • FIG. 2 is a sectional view of an essential portion of the elevator hatch door apparatus in embodiment 1 of the present invention.
  • the personal information of the authorized persons such as maintenance workers at the elevator maintenance company or caretakers for the building in which the elevator is provided is registered in an authentication device (not shown) in advance.
  • Reference numeral 6 denotes an unlocking limiter that enables the unlocking operation of the unlocking device 5 only when it is confirmed, based on the authentication result of the authentication device, that the authenticated person is the authorized person.
  • This unlocking limiter 6 is made up of a shield plate 6a for closing the unlocking hole 1a formed in the hatch door 1 and a solenoid 6b for opening and closing the unlocking hole 1a by moving the shield plate 6a vertically based on the authentication result of the authentication device.
  • the authentication device consists of a fingerprint identification system or an ID card reader provided additionally on the elevator apparatus, an authentication system for a password transmitted from a personal terminal such as a cellular phone, or the like. Also, in the case where the elevator is provided in an apartment house etc., the function of authentication device may be provided additionally in the building maintenance system of the apartment house etc. For example, as the authentication device, an authentication system for unlocking an automatic security lock system for a common entrance door can also be used.
  • the unlocking limiter 6 made up of the shield plate 6a and the solenoid 6b is shown.
  • the unlocking limiter 6 is not limited to this configuration if it has a function of enabling and disabling the unlocking operation of the unlocking device 5 based on the authentication result of the authentication device, namely, a function of removing or maintaining the unlocking operation limitation of the unlocking device 5 based on the authentication result of the authentication device. That is to say, the unlocking limiter 6 has only to have the configurations of the locking device 4 and the unlocking device 5 of the hatch door apparatus and have the configuration and operation matching the unlocking method of the unlocking device 5.
  • the configuration may be such that a braking device for braking the operating portion 5a of the unlocking device 5 is provided as the unlocking limiter 6, and only when it is confirmed by the authentication device that the authenticated person is the authorized person, the braking device is released, by which the unlocking operation of the unlocking device 5 is enabled, namely, the unlocking operation limitation of the unlocking device 5 is removed.
  • the locking device 4 and the unlocking device 5 are also not limited to the above-described configurations, and the unlocking hole 1a need not necessarily be formed in the hatch door 1.
  • FIG 3 is a flowchart showing the operation of the unlocking limiter 6 in embodiment 1 of the present invention.
  • Step S305 the unlocking operation of the unlocking device 5 is permitted (Step S306), and the unlocking operation limitation of the unlocking device 5 imposed by the unlocking limiter 6 is removed. Therefore, by performing a predetermined operation or input on the unlocking device 5, the locking device 4 can be unlocked (Step S307).
  • the shield plate 6a is moved upward by the solenoid 6b, so that the unlocking operation of the unlocking device 5 can be performed by inserting the special-purpose key 7 into the unlocking hole 1a from the elevator hall side.
  • the unlocking operation of the unlocking device 5 is enabled by imposing time limitation, and to disable the unlocking operation after predetermined time has elapsed after the authentication using the authentication device. That is to say, after the predetermined time has elapsed, the unlocking operation of the unlocking device 5 is limited by the unlocking limiter 6, by which the subsequent unlocking operation is prevented from being performed by the third person. Concretely, the shield plate 6a having been moved upward by the solenoid 6b at the time of authentication of the authorized person is moved downward to close the unlocking hole 1a after the predetermined time has elapsed.
  • predetermined time is required from when the authenticated person receives authentication of the authorized person to when the authenticated person performs the unlocking operation of the unlocking device 5.
  • time limitation may be imposed such that the unlocking operation of the unlocking device 5 is first enabled after predetermined time based on the distance between the installation position of the authentication device and the installation position of the unlocking device 5 or the movement from the installation position of the authentication device to the installation position of the unlocking device 5 has elapsed after the authentication using the authentication device.
