Abstract

PURPOSE:To provide an illumination device for an elevator cage capable of coping easily with an illumination plate having different thicknesses and needing no operating through holes for a supporting frame body. CONSTITUTION:A frame body 4 below a ceiling surface 2 supports the outer peripheral edge of an illumination plate 6. Also, the lower edge of a holding piece 8 is fixed to the frame body 4 and extends upward so that the upper edge is bent to the illumination plate 6 side and a holding part 81 is provided spaced above from the illumination plate 6. Thus, the upward displacement of the illumination plate 6 from the frame body 4 is blocked at a predetermined position by a holding section 81. Also, the holding piece 8 is flexibly bent to lift the illumination plate 6 over the predetermined position and remove downward the illumination plate 6 under the inclined position from the frame body 4. Thus, unified members of the holding piece 8 and frame body 4 can cope with the illumination plate 6 having different thicknesses to save production cost. Also, light is not leaked from the edge of the illumination plate 6 to make the illumination plate attractive.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device for an elevator car, which is mainly installed as a light ceiling.

[0002]

2. Description of the Related Art FIGS.
It is a figure which shows the illuminating device of the conventional elevator cage shown by the 906 publication. In the figure, 1 is an elevator car, 2 is a ceiling surface of the car 1, 3 is a side plate hanging from the ceiling surface 2, 4 is a frame body fastened to the lower end of the side plate 3, and a support portion 41 and a fastening portion 42 are provided. Has been formed. Reference numeral 5 denotes a light source body made of a fluorescent lamp mounted on the ceiling surface 2, 6 an illumination plate made of a louver for illumination, the outer peripheral portion of which is supported by the support portion 41 and arranged to face the light source body 5, and 7 A holder made of an elastic material, the upper end of which is fixed to the upper edge of the fastening portion 42, and the holding portion 71 and the holding portion 7 are provided at a position separated from the upper surface of the hanging illumination plate 6.
1 is further refracted and the operation portion 72 facing the through hole 43 of the hanging portion 42 is provided.

The conventional elevator car illumination device is constructed as described above, and the illumination plate 6 is supported by the support portion 41 of the frame body 4 at the outer peripheral edge portion thereof as shown in FIG. 3 near the ceiling surface 2 of the car 1. Is located in. In addition, the holding portion 71 of the holding member 7 prevents the illumination plate 6 from excessively rising and prevents the illumination plate 6 from unintentionally coming off the frame body 4. When the light source body 5 is replaced and the illumination plate 6 is removed, the following work is performed. That is, from the state shown in FIG. 4 by pushing up the illumination plate 6, between the lower surface of the illumination plate 6 and the support portion 41 of the frame body 4,
As shown in FIG. 6, a rod-shaped tool is inserted to push the operating portion 72 of the holder 7 into the through hole 43. As a result, the holding portion 71 of the holder 7 is retracted from the outer edge of the illumination plate 6, and the illumination plate 6 is pushed further upward and slanted.
Is removed downwards.

[0004]

In the conventional elevator car illuminating device as described above, it is necessary to change the vertical position of the holding portion 71 of the holding element 7 according to the thickness of the illuminating plate 6, and the holding portion 71 is held. There is a problem that it is difficult to unify the members such as the child 7 and the fastening portion 42 of the frame body 4. Further, there is a problem that the light of the light source body 5 easily leaks from the through hole 43 of the frame body 4.

The present invention has been made in order to solve such problems, and an elevator which does not need a through hole for operation in a frame can be applied to an illumination plate having a different thickness due to a holder made of the same member. The purpose is to obtain a car lighting system.

[0006]

In a lighting system for an elevator car according to the present invention, a translucent lighting plate having an outer peripheral edge portion supported by a frame body installed below the ceiling surface is provided, The lower edge is fixed to the frame and extends upward and is located above the outer peripheral edge of the lighting plate, and the upper edge is bent toward the center of the lighting plate and is separated from the upper surface of the lighting plate. A holding piece made of an elastic plate material having a holding portion arranged is provided.

[0007]

In the elevator car illumination device constructed as described above, the upward displacement of the illumination plate from the frame is blocked at a predetermined position by the holding portion of the holding piece. Further, the holding piece is bent to raise the illumination plate beyond a predetermined position, and the illumination plate is removed downward from the frame body in an inclined state.

[0008]

1 to 2 are views showing an embodiment of the present invention, in which the same reference numerals as those in FIGS. 3 to 6 indicate the corresponding parts, and 8 indicates the fastening of the frame body 4 at the lower edge. A holding piece made of an elastic plate material that is fixed to the portion 42 and extends upward and is arranged above the outer peripheral edge portion of the illumination plate 6, and the upper edge portion is bent toward the center of the illumination plate 6 and the upper surface of the illumination plate 6 is formed. The holding portion 8 arranged apart from above
1 is provided.

In the elevator car illuminating device constructed as described above, the illuminating plate 6 is supported by the supporting portion 42 of the frame 4 as shown by the solid line in FIG. When the illumination plate 6 is pushed up in this state, the upward displacement is blocked by the holding portion 81 at a predetermined position as shown by the chain line in FIG. This prevents the lighting plate 6 from floating and accidentally falling. When removing the illumination plate 6, the illumination plate 6
2 to the predetermined position and hold the holding piece 8
Is pushed outward in the frame 4 to disengage the holding portion 81 and the illumination plate 6. Then, the illumination plate 6 is removed downward by further raising and inclining the illumination plate 6. With this configuration, it is not necessary to change the size of the holding piece 8 even if the thickness of the illumination plate 6 is different, and the holding piece 8 and the fastening portion 42 of the frame body 4 can be unified. , Can reduce the manufacturing cost. Further, since the through hole of the frame body 4 is not necessary, it is possible to eliminate the light leakage of the light source body 5 such as between the outer peripheral edge portion of the illumination plate 6 and the support portion 41 of the frame body 4.

[0010]

As described above, according to the present invention, a translucent illumination plate having an outer peripheral edge portion supported by a frame body which is installed at a lower position from the ceiling surface as described above, and the lower edge portion is a frame body. Elasticity that has a holding part that is fixed and extends upward, faces above the outer peripheral edge of the lighting plate, and has its upper edge bent toward the center of the lighting plate and separated from the upper surface of the lighting plate. A holding piece made of a plate material is provided. As a result, upward displacement of the illumination plate from the frame is blocked by the holding portion of the holding piece at a predetermined position, and the holding piece is bent to raise the lighting plate beyond the predetermined position, so that the lighting plate is tilted. It can be removed downward from the frame. Therefore, it is not necessary to change the size of the holding piece even if the thickness of the illumination plate is different, and it is possible to unify the holding piece, the fastening portion of the frame body, and the like, which has the effect of reducing manufacturing costs. Further, the through hole of the frame is not necessary, and there is an effect that the light leakage of the light source from the outer peripheral edge of the illumination plate and the support of the frame is eliminated and the appearance of the illumination device is improved.
