Definitions

  • the present invention relates to a hatch door apparatus provided on an elevator hall.
  • An elevator door is made up of a hatch door for closing a hall entrance on an elevator hall of a building and a car door for closing a car entrance moving up and down in an elevator shaft.
  • the opening/closing operation for both of these doors is generally performed by a door operator provided on the car.
  • a door clutch provided on the car door and the hatch door engage each other, and thus the driving force of the door operator is transmitted to the hatch door via the car door. That is to say, the hatch door is opened and closed in association with the car door.
  • the hatch door on an elevator hall at which the car is not stopping is always closed, and is further locked by a locking device from the elevator shaft side to prevent the hatch door from being opened inadvertently at the time of being closed.
  • FIG. 6 is a sectional view showing an essential portion of a conventional elevator hatch door apparatus.
  • an unlocking device 5 for unlocking a locking device 4 for the hatch door 1 is provided on the side surface on the shaft side of a hatch door 1.
  • This unlocking device 5 is provided with an operating portion 5a so that the locking device 4 is unlocked, for example, by moving this operating portion 5a to one side.
  • an unlocking hole 1a penetrating from the elevator hall side to the shaft side is formed.
  • This unlocking hole 1a is arranged so as to be located at almost the same position as the lower end portion of the operating portion 5a of the unlocking device 5 at the opening of the hall side. Therefore, when the hatch door 1 must be opened, for example, at the time of maintenance, a maintenance worker dispatched from an elevator maintenance company inserts a special-purpose key 7 in the unlocking hole 1a from the elevator hall side to move the operating portion 5a of the unlocking device 5 to one side by using this special-purpose key 7, thereby unlocking the locking device 4 for the hatch door 1.
  • the present invention has been made to solve the above problems, and accordingly an object thereof is to provide an elevator hatch door apparatus capable of preventing a locking device for a hatch door surely and easily from being unlocked by a person other than an authorized person.
  • An elevator hatch door apparatus related to the present invention comprises a hatch door provided on an elevator hall; a locking device for locking the hatch door; an unlocking device for unlocking the locking device; an authentication device for authenticating an authorized person who is authorized to unlock the locking device; and an unlocking limiter for enabling an unlocking operation of the unlocking device based on an authentication result of the authentication device.
  • the present invention is configured by comprising a hatch door provided on an elevator hall; a locking device for locking the hatch door; an unlocking device for unlocking the locking device; an authentication device for authenticating an authorized person who is authorized to unlock the locking device; and an unlocking limiter for enabling an unlocking operation of the unlocking device based on an authentication result of the authentication device. Therefore, the locking device for the hatch door can be prevented surely and easily from being unlocked by a person other than the authorized person.
  • FIG 1 is a front view of an elevator hatch door apparatus in embodiment 1 of the present invention, showing a state in which the hatch door apparatus is viewed from the elevator shaft side.
  • 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.
  • the state in which the unlocking hole 1a in the hatch door 1 is closed by the shield plate 6a is maintained, so that even if a special-purpose key 7 is inserted into the unlocking hole 1a from the elevator hall side, the unlocking operation of the unlocking device 5 cannot be performed.
  • 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.
  • the state in which the unlocking operation of the unlocking device 5 is limited by the unlocking limiter 6 after the authentication using the authentication device is set so as to be slightly longer than the time necessary for the movement from the authentication device to the unlocking device 5, by which the unlocking operation of the unlocking device 5 can surely prevented from being performed by the third person during the time when the authorized person arrives at the installation place of the unlocking device 5.
  • a sensor may be provided to detect an unlocking operation intended to unlock the locking device 4 performed when authentication is not given by the authentication device, namely, when the unlocking operation of the unlocking device 5 is limited by the unlocking limiter 6.
  • This sensor is configured so as to detect not only the fact that the unlocking operation of the unlocking device 5 has been performed actually but also the operation intended to unlock the locking device 4. Concretely, a force acting on the shield plate 6a is measured by the sensor, and if a force higher than a predetermined value acts on the shield plate 6a, the force is detected as the unlocking operation intended to unlock the locking device 4.
  • a reporting device is provided to report the detection result obtained by the sensor to the outside such as an elevator remote control system or the building maintenance system, by which a mischievous unlocking operation performed by the third person can be monitored at any time. Also, in the case where an unlocking operation intended to unlock the locking device 4 is detected by the sensor, an alarm may be given to that elevator hall.
  • control of authorized person can be carried out easily by providing a recorder for recording the authentication history of authorized person authenticated by the authentication device.
  • a transmitter may be provided to transmit the authentication history recorded by the recorder to the outside such as an elevator remote monitoring system or the building maintenance system.
  • a releasing device for removing the unlocking operation limitation of the unlocking device 5 imposed by the unlocking limiter 6 regardless of the authentication result of the authentication device may be provided in a maintenance space such as a control panel in the machine room or a control panel mounted in the car.
