Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to a floor display device for an elevator car, which is provided in an elevator car and has a light source and a floor display section illuminated by the light source. .

[Conventional technology]

In general, a floor display having a floor display section for displaying each floor and a light source for illuminating the floor display section, which is arranged on the back side of the floor display section, is provided above the door in the elevator car. A device is provided. Such a floor display device requires replacement of the light source when the life of the light source has expired.

[Problems to be solved by the device]

Since the above-mentioned light source is housed in one frame body that forms a fixed object, and the work for removing the inside of the frame body is large-scale work, it is not easy to replace this light source, and this makes it easy to replace the light source. There was a demand for a replaceable means.

Although different from the present invention, as a floor display device on the landing side, a floor display unit is divided into a fixed case and a movable case, and a light source is attached to the movable case.
It is proposed in Japanese Patent No. 172461. However, the car to which the present invention is applied has a peculiar structure in which the mounting frame of the rail for the car door is usually located near the rear surface of the floor display device. If you try to apply it to the car as it is, the movable case will interfere with the mounting frame of the above car door rail, so you cannot open the movable case, you can not replace the light source placed inside, After all, this conventional technique is effective for the landing, but cannot be applied to the car.

The present invention has been made in view of the above circumstances in the prior art, and an object thereof is to provide a floor display device for an elevator car that can easily perform a light source replacement work.

[Means for solving the problem]

In order to achieve this object, the present invention is arranged in front of a rail mounting frame for a car door, and is housed in an upper frame located above the car door, and includes a floor display section and A fixed case having a first guide extending in the up-down direction, and arranged on the fixed case so as to be slidable only in the up-down direction, guided by the first guide, and moved upward from the first guide. And a movable case having a light source for illuminating the floor display section, and the movable case is mounted on the fixed case via an elastic body. .

[Action]

Since the present invention is configured as described above, the movable case having the light source is kept mounted on the fixed case having the floor display section while the light source is sufficiently usable.
A floor display is performed by illuminating the floor display section with a light source. When the light source needs to be replaced, the second guide of the movable case may be guided by the first guide of the fixed case and slid upward. When moving, the movable case does not interfere with the mounting frame of the rail for the car door, so that a working space for light source replacement is formed between the fixed case and the movable case, and the light source can be easily replaced. be able to.

Further, since the movable case is placed on the fixed case via the elastic body, the elastic body can absorb the deviation of the vibration between the movable case and the fixed case due to the lifting operation of the car. You can

〔Example〕

An embodiment of a floor display device for an elevator car according to the present invention will be described below with reference to the drawings.

1 and 2 are explanatory views showing an embodiment of the present invention, FIG. 1 is a side sectional view of an essential part, and FIG. 2 is a perspective view showing a state in which a floor display is removed.

As shown in FIG. 1, in this embodiment, basically, a fixed case 4 having a floor display portion 2 and a first guide 7 extending in the vertical direction, and a fixed case 4 is slidable on the fixed case 4. The second guide 11 arranged and guided by the first guide 7 described above.
And a movable case 10 having the above-mentioned structure, which is arranged in front of the rail mounting frame 3 for the car door and is housed in the upper frame 1 located above the car door.

The above-mentioned floor display portion 2 has a protruding portion that slightly protrudes from the opening formed in the upper frame 1, and each floor character is formed on this protruding portion. Further, the fixed case 4 forms a space corresponding to each floor character formed on the floor display unit 2, as is clear from FIG. 2 showing a state where the floor display unit 2 is removed. , A plurality of partition plates 5 are provided. The bottom of the fixed case 4 is formed with a reflecting surface 6 for reflecting light and efficiently illuminating the floor characters of the floor display unit 2. A pair of the above-mentioned first guides 7 are provided at positions forming both side portions of the fixed case 4. A plate-shaped elastic body 13 is extended above the front side of the fixed case 4.

On the other hand, the movable case 10 arranged above the fixed case 4
Has a pair of second guides 11 extending in the vertical direction so as to be in sliding contact with the first guide 7 of the fixed case 4, and has a frame portion forming a U-shaped space at a lower position. A light source 8 is attached to the lower end of the section. The light sources 8 are provided one by one, for example, corresponding to the above-mentioned floor characters. In addition,
The wiring 9 connected to the light source 8 is housed in the U-shaped space. Further, a grip 12 that can be gripped by an operator is provided so as to connect the upper portions of the pair of second guides 11 of the movable case 10 to each other.

The movable case 10 described above is arranged such that the lower end of the frame portion forming a U-shaped space is placed on the elastic body 13 provided in the fixed case 4 as shown in FIG.
It is fastened integrally to the fixed case 4 by 14.

In the embodiment constructed in this way, the light source 8 is kept in the state shown in FIG. The floor can be displayed by reflecting and illuminating the corresponding floor character on the floor display unit 2. Further, during the raising and lowering of the car and the stopping operation from the raising and lowering, the deviation of the vibration between the movable case 10 and the fixed case 4 is absorbed by the elastic body 13,
As a result, there is no rattling between the movable case 10 and the fixed case 4, and hence no vibration noise due to this rattling.

Then, when the light source 8 becomes old or cuts out, first, the car is put into maintenance operation and the light source 8 is operated from the floor side.
So that it can be reached, open the door on the floor on the rear floor,
Next, after removing the bolt 14 shown in FIG. 1, the grip 12 may be grasped and the movable case 10 may be slid upward as illustrated in FIG. The movable case 10 having the light source 8 can be lifted up without interfering with the rail mounting frame 3 for the passenger car door, whereby the working space for the replacement of the light source 8 is fixed case 4 and the movable case.
The light source 8 is formed between the light source 10 and the light source 10 and can be easily replaced.

[Effect of device]

Since the floor display device of the elevator car of the present invention is configured as described above, the sliding of the movable case having the light source can be performed regardless of the existence of the rail mounting frame for the car door peculiar to the car. This makes it possible to easily replace the light source and improve the efficiency of the replacement work as compared with the conventional one.

Further, since the elastic body is interposed between the movable case and the fixed case, the elastic body can absorb the deviation of the vibration between the movable case and the fixed case due to the lifting operation of the car. As a result, it is possible to prevent the occurrence of rattling between the movable case and the fixed case, and therefore, the vibration noise caused by such rattling is not generated, and it is possible to improve It is possible to ensure quietness.
