Description

[Detailed Description of the Invention] This invention relates to an elevator car lighting system in which a lighting fixture is attached to the ceiling.

A conventional cab lighting device of this type will be explained with reference to FIGS. 1 and 2.

In Figure 1, 1 is the elevator car room, 2
The ceiling of the car room 1, 3 is a side wall of the car room 1, 4 is a lighting fixture fixed to the lower surface of the ceiling 2 by appropriate means, and 5 is a lighting fixture arranged inside the side wall 3 and fixed to the lower surface of the ceiling 2. The hanging surrounding walls 6a and 6b are joint members fixed to the lower part of the surrounding wall 5, and the joint members 6a and 6b partition the lower opening of the surrounding wall 5 into a plurality of parts. Reference numeral 7 denotes a light-transmitting illumination plate made of a bright white synthetic resin plate, etc. The illumination plate 7 is formed approximately in the shape of a rectangular plate, and the outer peripheral portion 7a is connected to the joint members 6a, 6b.
It can be attached and detached from the inside of the car compartment 1 by lifting one side part from the joint member and tilting it. Reference numeral 8 designates a lifting prevention buffer member made of a flexible material such as sponge tape, which is fixed to the joint plate 6b having an inverted T-shaped cross section and placed on the outer periphery 7a of the lighting plate 7.

In the conventional double-ceiling type car lighting device configured as described above, when the buffer member 8 is not provided,
When the lighting board 7 is pushed up from inside the car room 1, it tends to float up from the joint members 6a, 6b, and there is a risk that the lighting board 7 will tilt, come off the joint members 6a, 6b, and fall. Also, to prevent this,
If the cushioning material 8 placed above the outer periphery of the lighting board 7 is fixed to the joint member, the lighting board 7 can be prevented from falling, but there is a problem in that it becomes difficult to attach and remove the lighting board 7.

This invention is an attempt to solve the above-mentioned problem, and includes a spring plate in which a lifting prevention part is formed on a member fixed to the ceiling, such as a joint member.
By providing an escape hole into which the lifting prevention part can be fitted, an elevator car lighting system is provided in which the lighting board can be prevented from falling due to lifting, and the lighting board can be easily attached and removed from the car interior. is intended to provide.

An embodiment of this invention is shown below in Figures 3 to 5.
The diagram will be explained.

In FIGS. 3 to 5, the same reference numerals as in FIGS. 1 and 2 indicate the same or corresponding parts, and 9 is a spring plate whose upper end is fixed to the vertical part of the joint member 6b. , a horizontal lifting prevention part 10 is formed in the intermediate part so as to protrude above the outer peripheral part 7a of the lighting plate 7 together with the oblique side 10a, and the lifting prevention part 10
A lower portion 12 is integrally formed below the upper portion 11 of the spring plate 9 so as to form a substantially flat surface. 1
3 is a relief hole formed in the joint member 6a;
The relief hole 13 is formed in a horizontally elongated shape with a horizontal length longer than the width of the spring plate 9, and the lifting prevention part 1
The height is from above 0 to below the lower part 12. Further, reference numeral 14 denotes a lifting prevention pin, which is fixed to the outer circumferential joint member 6a having an angular cross section, facing substantially horizontally to the lifting preventing portion 10 of the spring plate 9. In addition,
The configuration of this embodiment other than that described above is the same as that shown in FIGS. 1 and 2, and therefore the description thereof will be omitted.

In the car lighting device of the embodiment configured as described above, in normal times, even if the lighting plate 7 floats up from the joint 6b, it comes into contact with the floating prevention part 10 of the spring plate 9 and stops. It is possible to prevent the illumination plate 7 from coming off from the 6b and falling. To remove the lighting board 7 from inside the car compartment 1, as shown in FIG.
is inserted between the outer peripheral part 7a and the joint member 6b, and presses the lower part 12 of the spring plate 9, thereby elastically deforming the spring plate 9 and forcibly fitting the lifting prevention part 10 and the lower part 12 into the escape hole 13. and the outer peripheral part 7a of the illumination plate 7
The sides of the spring plate 9 are tilted, and the light plate 7 can be tilted at an angle sufficient for removal without coming into contact with the anti-lifting part 10. Therefore, the light plate 7 can be easily removed from inside the car compartment 1. Can be removed. Also, the installation of the lighting board 7 is different from the above-mentioned removal.
It can be easily done in almost the same way. Furthermore, when attaching or detaching the illumination plate 7 from above the enclosure wall 5, the operator presses the lifting prevention part 10 of the spring plate 9 with his/her finger to fit it into the relief hole 13, so that the illumination plate 7
can be easily removed and installed.

FIG. 6 shows another embodiment of this invention. In FIG. 6, the same reference numerals as in FIG. 3 indicate the same or corresponding parts. In this embodiment, a spring plate 9 and a relief hole 13 are provided in the outer peripheral joint member 6a having an angular cross section, and a lower part 12 of the spring plate 9 is provided. are located on the outer circumferential side of the joint member 6a, and the configuration other than these is the same as that shown in FIGS. 3 to 5. and,
The operation for attaching and detaching the light plate 7 is also shown in FIGS. 3 to 5, except for inserting a tool 15 such as a screwdriver between the side wall 3 of the car room 1 and the joint 6a and pushing the lower part 12 of the spring plate 9. It is similar to that.

This invention can also be applied to a car without a joint member by providing spring plates and relief holes in the wall surrounding the lighting equipment.

As explained above, in the car lighting device of this invention, a part of the spring plate 9 is fixed to members such as the joint members 6a and 6b fixed to the ceiling 2, and the spring plate 9 is
The lifting prevention part 10 located on the outer peripheral part 7a of the illumination plate 7 is made to protrude, and the lifting prevention part 1
A fitting escape hole 13 is formed in a member fixed to the ceiling 2, and when the appliance 15 is applied to the spring plate 9 from inside the car room 1, the lifting prevention part 10 is inserted into the escape hole 1.
3 so that the illumination plate 7 can be floated, so that it is possible to prevent the illumination plate 7 from falling due to the floating of the illumination plate 7, and at the same time, it is possible to easily attach and detach the illumination plate.
