Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention] (Industrial application field) The present invention relates to a floor position display of an elevator car.

(Prior Art) Many office buildings, hotels, condominiums, etc. are equipped with a number of elevators serving as vertical transportation, and are used by many people. More recently, it has even been installed in private homes.

What is required of such a popular elevator is
Anyone can use it in the same way, and can operate and get on and off without being confused with any elevator.

By the way, an outline of the actions to be performed by the user when getting on and off the general elevator and the driving operation are as follows: (1) Call of an elevator hall (hereinafter referred to as a hall call) (2) Ride on an elevator car.

(3) Call for destination floor (hereinafter referred to as car call) (4) Look at the floor display to see if the elevator car has arrived at the destination floor.

(5) Get off the elevator car.

It is.

In order to reduce the burden of passenger movement,
There are also ways to appeal to the eyes and ears, such as flashing or chimes of hall lanterns when an elevator arrives and an auto-announcement of a stop floor.

By the way, most of the elevator installers and users tend to dislike the sound device among them, and it is usually installed mainly in an office building. Therefore, most elevators are based on a service that appeals to passengers with a display device such as a lamp.

By the way, operations performed by elevator passengers in the car,
And the act of making a car call as described in the above (3) and (4), and seeing the display device when the user arrives at the destination floor, and the latter is the most frequently performed of these. Passengers are constantly watching the floor display to get to the destination floor.

On the other hand, crime in elevators is increasing in recent high-rise apartments, and one of the defense measures is to add windows to the doors of the car doors so that they can be seen from the outside, thereby preventing closed rooms.

In such an elevator, passengers are often attracted to the outside view from the window, unlike ordinary elevators. Also, in the case of late-night use, the window is used as a mirror to watch the behavior of passengers for the above-mentioned crimes, so watch the passengers closely.

(Problems to be Solved by the Invention) As described above, in the elevator car with the window 1, the passenger pays more attention to the window, and as shown in FIG.
The floor display device 2 above the passenger may not be in the field of view and may possibly get over. Otherwise, it is necessary to look at the floor display device every time the vehicle stops, and it is not possible to prepare for getting off the vehicle, so that the passenger gets down in a hurry and troubles other passengers. In addition, as a result, the travel time generally becomes longer and the service to other hall waiters is reduced.

Another similar elevator is an observatory elevator that is constructed entirely of glass plates so that the outside scenery can be seen. In this case, since there is a window on the opposite side of the car door, the customer is looking at the outside scenery, and the floor may not be understood at all.

Conventionally, as a countermeasure against such a problem, a method of attaching a floor display device to the window side has also been performed. However, since the mounting position is above or on the side of the window, it has no effect because it does not enter the field of view of the user. Further, such a display device requires a mounting space, and thus has a problem in design.

As described above, an elevator car having a window differs from a general elevator in terms of convenience in use, often resulting in confusion for customers.

Therefore, the present invention is intended to provide a display device that is easy to see as well as a general elevator, with the floor position display in the passenger's view without obstructing the view from the outside of the window.

[Configuration of the Invention] (Means for Solving the Problems) The present invention mounts a floor position display device in a window glass for viewing the outside so that information can be naturally entered into the field of view of the user. It is.

In FIG. 1, a display unit 4 having a transparent electrode is attached to the outside of a window glass 3 attached to a car, and a floor signal sent from an elevator control unit 5 is transmitted to a control unit in the car by a signal for the display unit. And a signal is sent to the glass plate on which the transparent electrode is placed through a wiring pattern on the film.

(Operation) With this configuration, the structure of the display molecule on the transparent electrode to which a voltage is applied changes, blocking external light and performing floor display in the window.

Also, the transparent electrode to which no voltage is applied passes external light,
The floor display viewed from the user has a form in which floor display characters are raised above the outside scenery, and since the display element is not a light-emitting body, information can be input without looking away.

(Embodiment) In FIGS. 1 to 5, the transparent display 4 attached to the window glass 3 of the car is divided into seven segments so as to display a floor position, for example, in a digital display. (Second
(See the figure). Further, the structure of the display will be described with reference to FIG.

The display can see only the transparent electrode when viewed from the outside. Front polarizer 6, Glass plate common electrode 7, Display molecule 8, Transparent electrode
9, composed of a rear polarizing plate 10. The display molecule 8 has a property that when a voltage is applied, the direction of the long axis of the molecule changes to block light. A typical example is a liquid crystal, which is used in computers and various displays.

The transparent electrode 9 is formed of a thin wiring pattern for connecting a segment-shaped electrode and an externally input electrode. However, since only a low voltage (3 to 20 V) is applied to this electrode and almost no current flows (about 1 mA), a film-like pattern is used. The front polarizer 6 and the rear polarizer 10 are arranged so that their polarization directions are shifted from each other by 90 degrees to enhance the light blocking effect. Since these configurations can be configured with a thickness of about 2 mm as a whole, they can be attached without affecting the car.

In FIG. 2, the floor signal transmitted from the elevator control device 5 is transmitted to the elevator car 11 via a tail cord, and is converted into a signal capable of driving the display by the conversion unit 12 on the elevator car.

With such a circuit configuration, floor display is realized on a window in an elevator car.

The display molecule on the electrode to which the voltage is applied changes its molecular structure as described above, and acts as a kind of shutter. In general, when the elevator car 11 has a window, outside light enters the elevator car 11 through the window, so that only the floor letters can be seen. FIG. 4 shows a case where floor letters are processed by the static driving method.

Floor signals are usually sent from the elevator control as binary signals. Since this signal is often a DC 24 V voltage, the decoder 13 in the conversion unit 12 converts the binary signal into a 7-segment signal by means of insulation by a photocoupler, signal level conversion, and a diode matrix. The latch 14 is a device that holds the output of the decoder 13. The segment driver 15 is a device for converting the driving voltage of the display body into a driving voltage. The segment driver 15 is configured by a transistor or an FET and is connected to the transparent electrode 9. The common driver 16 supplies a voltage supplied from a power supply to a common electrode of the display.
The decoder 13 and the latch 14 often use TTL elements, and the power supply voltage is about 5V.

In FIG. 5, a front glass plate 18 for protecting the display body and improving visibility is provided outside the glass plate 3 of the window, and a display body.
Next, a light diffusion plate 19 for preventing display unevenness, and a flexible substrate 20 supporting the above-described components and including a wiring pattern are provided. These components are all transparent, and transmit external light input from the back surface of the flexible substrate 20.

Further, in the normal case, since the outside of the car is also made of glass, an external impact is not directly applied to the display body, so the above configuration is sufficient.

It is also possible to make the glass plate of the window double and to sandwich the display body between them.

In addition, the flexible substrate has a shape in which a wiring pattern is placed on a film-shaped element, and is often used for general liquid crystal displays. However, in the present invention, the flexible substrate is used for protecting a display body and fixing it to a window. It is. This makes it possible to configure the floor display with only a transparent material.

You.

As shown in FIG. 5, the constituent elements of the present invention are as follows.
The point is that a liquid crystal display is attached to the outside of a general glass plate, integrated with the glass plate by a flexible substrate including a wiring pattern, and external light is used as a backlight.

Since this external light is not a flat light-emitting body as employed in a general display, but a light source that changes every moment, a light diffusing plate 19 is required. At the same time, this light diffusion plate
Reference numeral 19 plays a role of adjusting external light. For example, when sunlight is directly input to the display, the life of the display is shortened, so that the display has a characteristic of blocking ultraviolet rays.

[Effects of the Invention] The floor is displayed on the window glass of the elevator car, so that there is no oversight and the passenger can ride with confidence.

Since the display body is formed as a single package on the flexible board, it can be mounted at any position of the window, and there is a convenience such that the mounting position can be easily changed.
