DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting cover for an elevator cab.

[0002]

2. Description of the Related Art In FIG. 4 showing a view of a conventional elevator cab viewed from the inside of a car, a car door 9 which opens left and right is suspended on a rail (not shown) at the center of the front side of the cab 1, An operation panel 8 is provided on the right side of the door 9. On the other hand, an arched lighting unit is formed on the ceiling of the car room 1, and a lighting device (not shown) is attached to the center of the ceiling plate (not shown). A mounting plate 15 bent in a detailed shape is fixed in a direction perpendicular to the plane of the drawing with the opening side inward, and an end plate 16 having an arc-shaped lower end is fixed to an end of the mounting plate 15.

Further, between the left and right mounting plates 15, an illumination frame 12 bent in an arc shape is mounted in an arch shape at the front and rear ends of the left and right mounting plates 15 and the lower end of the central portion with the convex side facing upward. ing. Light-shielding plates 7 are fixed to the left and right ends of the upper surface of the illumination frame 12 between the illumination frames 12, and a strip-shaped acrylic resin illumination plate 13 is placed at an intermediate portion. As shown in FIG. 5 showing the AA cross section of FIG.

That is, in FIG.
In the middle of 12, the lower end of the welding stud 20 is welded, and between the upper surfaces of the respective lighting frames 12, a lighting plate 13 is placed.
13 is fastened from above by a nut 20a via a holding plate 14 inserted into the welding stud 20.

FIG. 6 is a detailed cross-sectional view taken along the line CC of FIG. 4. One side of an L-shaped mounting plate 10 is mounted on the inside of the lower end of the end plate 16 with a welding stud (not shown). Board
On the lower surface on the other side of 10, an illumination frame 12 is fixed with a welding stud 20 and a nut 20a.

[0006]

However, in the lighting cover of the elevator cab configured as described above,
Even if you tighten the nut 20a inserted in the stud 20
As shown in FIG. 5B, both sides of the lower surface of the illumination plate 13 do not completely adhere to the upper surface of the illumination frame 12, and the nut 20a only loosens due to minute vibration of the car moving up and down the hoistway (not shown). Instead, the light of the lighting fixture sometimes leaked into the cab 1 from a minute gap between the lighting frame 12 and the lighting plate 13.

[0007] Then, not only is the design of the car room 1 provided with the arched lighting cover, which is well-designed and manufactured in good shape, impaired, but also the adhesion between the lighting plate 13 and the lighting frame 12 is poor. If it is loose, the lighting plate 13 may fall out of the lighting frame 12 during long-term operation.

Therefore, conventionally, when increasing the number of the welding studs 20 and further tightening the nut 20a, the lighting plate 13 is pressed against the lighting frame 12 from the right end (or the left end) in FIG. Alternatively, the lighting plate 13 is tightened in the left-right direction while pressing the lighting plate 13 against the lighting frame 12 by tightening from the center. However, there is still a possibility that light from the lighting fixture leaks from the overlapping portion due to slight twist or the like generated when the lighting frame 12 is bent in an arc shape. Therefore, in order to completely prevent this light leakage, it is necessary to adjust the position of the lighting plate 13 in the horizontal direction many times in order to make the overlapping width of the lighting plate 13 and the lighting frame 12 equal in the left and right directions. Was taking a long time.

Therefore, an object of the present invention is to make adjustment easy,
An object of the present invention is to provide an elevator cab lighting cover capable of easily preventing light from leaking from an overlapping portion between a lighting plate and a lighting frame and exhibiting a design of the cab.

[0010]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of an elevator cab lighting cover according to an embodiment of the present invention. However, FIG.
5 and 6 are denoted by the same reference numerals, and description thereof will be omitted.

FIG. 1 is a partial longitudinal sectional view of a lighting cover and corresponds to FIG. 5 of the related art. In the same figure, after being formed into a substantially C-shaped cross section by an aluminum extrusion die, the illumination frame 2 bent in an arc shape is formed with a convex groove 4 having the same dimensions in the center and left and right in advance by the extrusion die. As a result, two T-shaped ribs 5B are formed at the center of the illumination frame 2 at the upper side, and inverted L-shaped ribs 5A and 5C protruding inward at the left and right.
Are formed, and these ribs 5A, 5B, 5C
Have the same height.

A rib 5C formed on the upper surface of the illumination frame 2
In the same manner as in the prior art, an acrylic resin lighting plate 3 is placed on both sides with a space between adjacent side surfaces, and a plurality of bolt holes are provided at the center on the upper surface between the side surfaces of the lighting plate 3. A band-shaped holding plate 11 provided at equal intervals is placed. These illuminating plates 3 are secured to the holding plate 11 by bolts 6 and nuts or the like previously inserted into the central groove 4 of the illuminating frame 2.
The lighting plate 3 is fixed to the lighting frame 2 by tightening.

FIG. 2 is a longitudinal sectional view of a portion of a light shielding portion provided on both sides of the illumination plate 3, and is a view corresponding to a cross section taken along line BB of FIG. Are provided with two mounting holes laterally, and the illumination frame 2 is fixed to the light shielding plate 7 with bolts 6 inserted into the left and right grooves 4 respectively.

FIG. 3 is a longitudinal sectional view corresponding to FIG. 6, showing a section taken along line CC of FIG. In FIG. 3, on the lower surface of the L-shaped mounting plate 10 fixed inside the lower end of the end plate 16,
The illumination frame 2 of the same product as the illumination frame 2 shown in FIG. 1 and FIG. 2 is provided with the left rib 5A in contact with the outer surface of the end plate 16, and similarly to FIG. The head is fixed to the mounting plate 10 with bolts 6 and nuts whose heads are inserted in advance in the central groove 4.

According to the lighting cover of the elevator cab thus constructed, the lighting frame 2 is fixed to the light-shielding plate 7 with two bolts in the width direction at both ends. Since three points of an isosceles triangle are supported by the bolts of the cover, it is possible to prevent the conventional inclination as shown in FIG. 5B, and to prevent the formation of a gap between the illumination plate 3 and the illumination frame 2. As a result, light leakage from the interior of the lighting cover into the car room can be prevented, and the design of the car room with an arched ceiling can be exhibited.

Furthermore, since the overlap between the illumination frame 2, the illumination plate 3 and the holding plate 11 can be increased, almost no adjustment is required at the time of assembling, and if necessary, the assembling becomes easy.

In the above embodiment, as shown in FIG. 1, the side surface on the adjacent side of the illumination plate 3 is located at the middle of the grooves 4 on both sides of the illumination frame 2, but may be overlapped with the rib 5B. Often, in this case, the overlap between the illumination frame 2 and the illumination plate 3 further increases, so that not only can they be more completely fixed but also light leakage can be further prevented.
