Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator car room ceiling lighting device for illuminating an elevator car room from the ceiling.

[0002]

2. Description of the Related Art FIG. 12 is a perspective view of an entrance side of an elevator car room seen from the rear side thereof, and is a sectional view showing a conventional elevator car room ceiling lighting device with a ceiling portion. 13 is a detailed cross-sectional view of the ceiling cab lighting device for the elevator car room in the ceiling of FIG. 12, and FIG. 14 is an enlarged view of part A of FIG.

In the figure, 1 is a canopy, 2 is an illuminating lamp arranged on the lower surface of the canopy 1, 3 is a suspended ceiling suspended from the canopy 1, and 4 is a suspended ceiling 3 perforated into a plurality of rectangular shapes. A long (transparent) acrylic block dropped into the transparent hole,
5 is a milky white acrylic plate placed on the acrylic block 4 for diffusing light, 6 is an L-shaped presser foot arranged on both sides of the acrylic block 4 in the longitudinal direction for fixing the milky white acrylic plate 5, 7 To ensure the rigidity of the suspended ceiling 3,
U-shaped reinforcing members, which are arranged alternately with rectangular light-transmitting holes on the upper surface of the suspended ceiling and welded and fixed, and 8 are bolts for fastening and fixing the L-shaped presser and the U-shaped reinforcing member 7.

[0004]

Since the conventional elevator cab room ceiling lighting device is constructed as described above, when the number of the long acrylic blocks 4 increases, the L-shaped presser foot 6 is used.
The number of bolts is increased, and the number of bolts 8 for mounting the bolts is very large, so that it takes too much time for assembling work. Also, since the L-shaped presser foot 6 is held by the frictional force of the bolts, if the bolts 8 loosen. There is a problem that the long acrylic block 4 may be scratched during transportation and may cause vibration, and the weight becomes heavy.

The present invention has been made to solve the above problems, and shortens the assembly work time and
The purpose of the present invention is to obtain a lighter elevator car ceiling lighting device without rattling.
