Description

  The present invention relates to a display device with a mirror function provided in an elevator car.

  In a general elevator, a mirror is provided on the front wall of the car. When a wheelchair user who gets into the front wall of the car gets out of the elevator, this mirror can come back safely while checking the landing situation reflected in the mirror provided on the front wall of the car. It is for doing it. However, when general passengers are riding in addition to wheelchair users, the above-mentioned mirror often causes wheelchair users to see the general passengers. There is. In order to solve this problem, conventionally, a shielding curtain is provided on the front surface of the mirror mounted on the wall of the car, and the mirror is exposed by lifting the shielding curtain in conjunction with opening and closing of the car door, or the mirror is closed. The wheelchair user can use the mirror by exposing it only while the mirror is needed, and the wheelchair user can use the wheelchair while the mirror is not needed (while the elevator is moving up and down). As a result, it is possible to reduce the number of eyes of general passengers as much as possible (see, for example, Patent Document 1).

JP-A-7-247081

  The conventional elevator car has no mirror function because the shield curtain is lowered during traveling, and is merely a mirror when stopped.

  The present invention has been made to solve the above-described problems, and has a mirror function only from a short time before the elevator door opens until the door is completely closed. For passengers including wheelchair users in the car room, such as those that have no function or have a mirror function, and display a video of the hall, an image of a car indicator, an image of scenery, etc. and text information The present invention provides a mirror-equipped display device for an elevator car that can provide various kinds of information and has high performance.

  In the display device with a mirror for an elevator car according to the present invention, the display device with a mirror in which the elevator car room is combined with the mirror and a flat panel display provided on the surface of the mirror, and the operation of the elevator A display content constituting unit configured to display a display image on the flat panel display in response to the status signal and a display driving device for displaying the display image on the flat panel display, the display image being at least one of the images depending on the driving state of the elevator. The display of the part is made transparent, and the reflection image of the mirror is made visible by passing through the flat display.

  According to the elevator car mirror display device of the present invention, for example, it has a mirror function only from a short time before the elevator door opens until the door is completely closed, and during the elevator lift other than that, the mirror function is disabled. Or a part of the mirror function, and display various information to passengers including wheelchair users in the car room, such as displaying the video of the hall, the image of the car indicator, the image of the landscape, etc. and the character information The effect that it can provide is acquired.

Embodiment 1 FIG.
FIG. 1 is an overall perspective view of a car room showing a display device with a mirror of an elevator car according to Embodiment 1 for carrying out the present invention, FIG. 2 is a front view showing a mirror function of the display device with a mirror, and FIG. FIG. 4 is a plan view of the elevator car according to Embodiment 1 of the present invention, FIG. 5 is a detailed view of part A of FIG. 4, and FIG. FIG. 3 is a control block diagram of the mirror-equipped display device of the elevator car in the first embodiment.

1 to 5, 1 is a front wall of an elevator car, 2 is a display device with a mirror, 3 is a wheelchair user, 4 is a wheelchair, 5 is a caregiver, 6 is a general passenger, and 7 is a car floor It is.
As shown in FIG. 5, the mirror-equipped display device 2 is configured by combining a mirror 2 a attached to the front wall 1 of the car and a flat display 2 b attached to the surface of the mirror 2 a. In the display device 2 with a mirror, the state 2c having a mirror function means that, as shown in FIG. 2, no voltage is applied to the flat display 2b attached to the surface of the mirror 2a. By making the display 2b transparent, the mirror 2a on the back surface is exposed and the mirror is reflected. Further, in the display device 2 with a mirror, the state 2d in which the function of the mirror is absent is, as shown in FIG. 3, by applying a voltage to the flat display 2b attached to the surface of the mirror 2a so as to be flat. The entire surface of the display 2b is colored to be opaque, and the mirror 2a on the back surface is covered to prevent reflection of the mirror.
In FIG. 6, reference numeral 8 denotes elevator car door opening / closing status data, elevator operation modes such as normal operation and wheelchair operation, elevator operation status signals for transmitting signals such as call floors and destination floors, and 9 an elevator operation status signal. 8 is a display content configuration means for selecting image data 10, audio data 11, and image / sound data 12 based on 8, and 13 is a display drive on the flat panel display 2b based on control from the display content configuration means This is a display driving device that drives the speaker 14.

From a short time before the elevator door opens until the door is closed, by controlling the flat display 2b of the mirror-equipped display device 2 so that no voltage is applied, the flat display 2b becomes transparent and the mirror 2a on the back surface is exposed. Therefore, the passenger in the car is reflected in the mirror as in the state 2c of FIG. 2, for example.
However, when the door is closed and the elevator starts to move up and down, the entire surface of the flat display 2b is colored by applying a voltage to the flat display 2b on the front surface of the mirror-equipped display device 2 as in the state 2d of FIG. It is opaque and covers the mirror 2a on the back surface to block the reflection of the mirror, thereby eliminating the function of the mirror. Then, the elevator arrives at the stop floor, and the state 2c of FIG.
By providing the above-described function, the mirror-equipped display device 2 is allowed to have a mirror function only while the wheelchair user needs, and while the wheelchair user does not need it, that is, when the elevator is lifted, the mirror-equipped display device 2. In order to eliminate the function of the mirror, the wheelchair user does not see the general passenger through the mirror.
Therefore, the wheelchair user can use the elevator comfortably because the stress as described above is reduced.

In FIG. 7, when the elevator starts driving and it is detected in step S1 that the wheelchair is called from the landing, the process proceeds to step S2, switches to the wheelchair driving mode, and arrives at the calling floor in step S3. Moreover, if it becomes wheelchair operation mode in a cage | basket | car in step S4 and destination floor registration is performed, it will progress to step S5 and will be switched to wheelchair operation mode. Next, the process proceeds from step S3 or S5 to step S6, and the mirror-equipped display device 2 is assumed to have a mirror function. Then, the destination floor of the wheelchair user is registered at step S7, the wheelchair user arrives at the registered destination floor at step S8, and the wheelchair user gets off at step S9. No mirror function. Then, in step S11, the elevator is switched to the normal operation mode, and the normal operation is performed (step S12).
In this second embodiment, when switching to the wheelchair operation mode, the mirror-equipped display device 2 is provided with the mirror function shown in FIG. 2 to ensure the safety of the wheelchair user, and when the wheelchair user gets off, The attached display device 2 is returned to the normal state in the car room as shown in FIG. 3 without the mirror function.
