A ceiling lighting device 4 is provided on a ceiling plate 3 of a car 2 of an elevator 1 shown in FIG. As shown in FIG. 2, the ceiling lighting device 4 includes a translucent lighting cover 5 provided so as to cover the opening 3 </ b> A provided in the ceiling plate 3, An instrument lid 7 having an illumination lamp 6 provided therein at an opposing position, and a height adjusting member 8 for securing a large space between the instrument lid 7 and the ceiling plate 3 are provided.

The instrument lid 7 is made of a steel plate, and is detachably provided on a height adjusting member 8 with a thumb screw 9. The height adjusting member 8 is made of a steel material, and is fixed to a fixing member 3a disposed on the upper surface of the ceiling plate 3 by welding or the like.
In the present embodiment, the opening 3A also serves as a rescue exit for passengers in the car 2. For this purpose, the instrument lid 7 can be detached from the height adjusting member 8 when necessary.

The height dimension H of the height adjusting member 8 is determined by raising one side of the lighting cover 5 and making the lighting cover 5 oblique as shown by the broken line in FIG. Is disengaged from the end face 3B of the opening 3A.
Is set to a size that can be detached below the opening 3A.

According to one embodiment configured as described above,
Since the replacement work of the illumination lamp 6 can be performed in the car 2, the replacement work can be performed safely in a short time.

4 to 7 are explanatory views showing another embodiment of the present invention. FIG. 4 is a schematic perspective view of a car equipped with another embodiment, and FIG. 5 is an enlarged sectional view taken along the line Y--Y of FIG. FIG. 6 and FIG.
Is a perspective view showing a height adjusting member and a shield plate provided in another embodiment shown in FIG. 7, and FIG. 7 is a perspective view showing an external configuration of another embodiment shown in FIG.

The ceiling plate 3 of the car 2 of the elevator 1 shown in FIG. 4 is provided with another ceiling lighting device 11 different from the above. This ceiling lighting device 11, as shown in FIG.
A light-transmitting illumination cover 5 covering an opening 3A provided in the steel plate ceiling plate 3, a steel plate device cover 20 covering above the illumination cover 5, and an inner wall of the device cover 20;
Further, it has a plurality of illuminating lamps 12 arranged at positions facing the illuminating cover 5 and the opening 3A. Illumination light 12
Consists of a ring-shaped fluorescent lamp.

As shown in FIG. 5, a folded rising portion 3C is formed near each of two opposing sides of the opening 3A of the ceiling plate 3, as shown in FIG. On each of the folded rising portions 3C, a height adjusting member 8 made of a steel plate is placed. These height adjusting members 8 have a substantially U-shaped cross section. A shielding plate 18 made of a steel plate is provided between the folded rising portions 3C. One end of each of the shielding plates 18 is provided with a fall prevention metal fitting 17 for the lighting cover 5 made of spring stainless steel having one end fixed and the other end protruding inward as a free end. As shown in FIG. 5, the one height adjusting member 8 is detachably attached to one of the folded rising portions 3C of the ceiling plate 3 by the thumb screw 15. The other height adjusting member 8 side is fixed to the other folded rising portion 3C of the ceiling plate 3 by welding or the like. One side of the instrument lid 20 is fixed to one of the height adjusting members 8 by bolts 16, and the other of the instrument lid 20 is fixed to the other of the height adjusting members 8 via hinges 14. .

The opening 3A of the ceiling plate 3 is set to a size large enough for one passenger to pass through the opening area. Therefore, by opening the instrument lid 20, the passenger in the car 2 can exit the car 2 through the opening 3A.

The height of the height adjusting member 8 is adjusted such that the space 13 formed between the appliance lid 20 and the ceiling plate 3 lifts one side of the lighting cover 5 and tilts it. 5 is set to a size that can be moved into the car 2 from the opening 3A of the ceiling plate 3 as shown by a broken line in FIG.

In another embodiment configured as described above, the replacement work of the illumination lamp 12 of the ceiling illumination device 11 is performed as follows.

First, an operator in the car 2 pushes up the lighting cover 5 slightly, inserts a jig such as a screwdriver into the clearance, and uses the jig to attach the fall prevention metal 17 to the shielding plate. 18 and press the lighting cover 5
Is not locked to the fall prevention fitting 10, and then one side of the lighting cover 5 is sufficiently lifted to hold the lighting cover 5 in an oblique state.

Then, one end of the lighting cover 5 is connected to the ceiling plate 3.
The illumination cover 5 is moved downward from the opening 3A, and one end of the illumination cover 5 is pulled down.

Next, the operator inserts his hand through the opening 3A of the ceiling plate 3 and replaces the old lamp 12 mounted on the inner wall of the instrument lid 20 with a new one.

Finally, the lighting cover 5 is inserted again through the opening 3A of the ceiling plate 3 in a state where the lighting cover 5 is inclined again.
Is returned to the original state as shown by the solid line in FIG. Thus, the replacement work of the illumination lamp 12 is completed.

In another embodiment having the above-described configuration, the replacement work of the illumination lamps 12 can be performed in the car 2 in a short time.
It can be done safely.

When a passenger is trapped in the car 2, an operator places a thumbscrew 13 on the car 2.
Is removed and the fixture lid 20 is opened, and the fall prevention bracket 17 is pressed against the shielding plate 18 using a jig such as a driver from the car 2 so that the lighting cover 5 is not locked to the fall prevention bracket 10. Then, the lighting cover 5 is lifted and removed. Thereby, the opening 3A of the ceiling plate 3 can be used as a rescue exit for passengers in the car 2.

Even if one side of the lighting cover 5 is simply lifted, the movement of the lighting cover 5, that is, lifting of the lighting cover 5 is prevented by the fall prevention metal fitting 17 projecting inward from the shielding plate 18. The lighting cover 5 does not fall out of the opening 3A and fall into the car 2.

Further, the gap formed between the folded rising portions 3C can be almost completely shielded by the shielding plate 18, so that the light of the illuminating lamp 12 can be prevented from leaking to the upper part in the car 2. Insects can be prevented from entering the lighting cover 5.

Since the instrument lid 20 is attached to the height adjusting member 8 via the hinge 14, the operation of opening and closing the instrument lid 20 can be easily performed.

[0032]

According to the invention of each claim of the present invention,
The replacement work of the lighting can be performed safely within a short time from inside the car.

In particular, according to the second aspect of the present invention, it is possible to prevent the light of the illumination lamp from leaking to the upper part in the car.

According to the third aspect of the present invention, it is possible to prevent the illumination cover from dropping when replacing the illumination lamp, thereby contributing to ensuring the safety of the replacement operation.

According to the fourth aspect of the invention, when the passenger is trapped in the car, the passenger can be rescued from the opening.

According to the fifth aspect of the present invention, the operation of opening the instrument lid can be easily performed via the hinge.
