Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a display device for displaying the status of an elevator.

[Technical background of the invention and its problems]

Conventionally, in the above type of display device, as shown in FIG. 1, a plurality of elevators la and lb are used.

There are elevators 1*, Ib,
indicators 4a, 4b; 4c, which display the status of le, 16;
4d is installed. These indicators 4a, 4b, 4e, 4
d includes hall lanterns 5h, 5b, 5c, and 5d for making service reservations and arrival forecasts; position indicators (not shown) for displaying the floor positions of elevators la, lb, la, and ld; elevators 1&, lb; There are direction indicators that indicate the direction of le and id, passing lights, full occupancy lights, stop lights, etc. These displays 4m, 4b, 4c @ 4d, etc. have almost the same installation structure, so for example, Hall lantern 5
If we add an explanation to h, 5b, 5c, and 5d, these hole run turns are 5m and 5b.

5e and 5rl are control devices installed in the machine room 6.

7b, 7e, and 7rl, respectively. That is, Torera hole lanterns 5a, 5b, 5c

The installation structure is connected to contacts 18 and 19 of 7d, respectively. In addition, 20 in Figure 1 is hall call registration? It is tan.

However, according to the above installation structure, each elevator 1
*, 15 mounting holes for each 70 ar of lb, le, ld...
・Since it is necessary to open the
It requires a lot of effort.

In addition, each elevator 1m, Ib, le, Id hoistway 1
6...The workability is poor because the wiring is routed through the inside.
The implementation cost is high.Furthermore, the hole run turn 5a
, 5b, 5c, 5d, etc. are often installed in high positions and are often dangerous when installed.

[Purpose of the invention]

The present invention has been made based on the above circumstances, and its object is to provide a display device that can be easily and safely installed.

[Summary of the invention]

The present invention is a display device for displaying the status of an elevator in the vicinity of its hall door, characterized by comprising a projector for projecting a predetermined display form image in the vicinity of the hall door.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 3 to 7. Reference numeral 21 in FIGS. 3 and 4 indicates a plurality of elevators 22th and 22b.

From near the center of the ceiling of the elevator hall 21, a predetermined display form image, such as a Hall Ranthal image 23, is displayed in the elevator hall 22a, 22d.

22e, 22d hall doors 24a, 24b.

A projector 25 for projecting images is suspended near 24Q and 24d. This projector 25 consists of a cover, and these light projecting units 27a and 27b.

27c and 27d are control devices 29a for the machine room 28;

It is connected to 29b, 29c, and 29d via wiring 30, respectively. Note that these wirings 30... are 1
They are centrally arranged through two hoistways (not shown).

Further, the above-mentioned light projection units 27*, 27b.

27c and 27d are the corresponding elevators 22*, 22b, 22c, 2, as shown in the diagram.
The mounting angle is adjusted so that light can be projected onto 2d.

Furthermore, the above-mentioned light projection units 271L, 27b.

17e and 27d, as shown in FIGS. 6 and 7, respectively, have a light emitting run f3, a concave mirror 32 for increasing the light emitting intensity of this lamp 31, and a green triangular slit 33. 5- A descending display unit 3 having an ascending display unit 34, a lamp 35 that emits light, a concave mirror 36 that increases the intensity of the light emitted from this lamp 35, and a red inverted triangular slit 37.
It consists of 8. Furthermore, the inner walls of the ascending display unit 34 and descending display unit 38 are coated with a light-absorbing material to prevent slippage). It absorbs light that does not pass through 3 and 37 and does not reflect it.

And elevators 22a, 22b, 22c.

(When 22d receives the assignment and starts decelerating in the upward direction,
Control devices 29h, 29b, 29c.

The contact 39 is closed at 29d, and the rising display unit 34
The lamp 3) lights up. Then, the light emitted from the lamp 31 passes through the slit 33 and enters the hall doors 24m, 24.
A green, triangular hall lantern image 23 is projected on the wall 40 above b, 24c, and 24d. Further, when the elevators 22h, 22b, 22c, and 22d start decelerating in the downward direction, the contact 41 is closed and the lamp 35 of the downward 6th downward display unit 38 is lit.

Then, the light emitted from this lamp 35 is visible.

The light passes through the lens 37, and a red, inverted triangular Hall Lantern image 23 is projected. The contacts 39 and 41 are configured to repeatedly open and close 11 about every second, so that the green lantern image 23 and the red lantern image 23 appear to be blinking.

According to the above configuration, the hall door 24a.

There is no need to drill mounting holes near 24b, 24c, and 24d, and each elevator 22m, 22b.

Since the wiring 30 for each of 22c and 22d can be concentrated in one hoistway or duct, the construction cost can be significantly reduced.

Also, since it is concentrated in one place, it is easy to maintain, perhaps because it is hard to get scratched. Furthermore, the dangerous work of mounting and wiring the display devices one by one while riding on the elevator ride becomes unnecessary.

〔Effect of the invention〕

As explained above, according to the present invention, a display device for displaying the status of an elevator near its hall door is equipped with a projector that projects a predetermined display form image near the hall door, so that it is easy and safe. It has excellent effects and can be installed at a low price.
