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 FIG. 4 shows, for example, JP-A-58-82928.
It is a figure which shows the conventional illuminating device of the elevator car shown by the publication. In the figure, 1 is a light source body made of a fluorescent lamp provided on the ceiling surface (not shown) of the elevator car, and 2 is an illumination case plate supported by the ceiling surface of the elevator car and arranged below the light source body 1. A large number of openings 3 are provided in the plate body. Reference numeral 4 denotes a translucent body provided with a flange portion 5 on the upper side and fitted into the opening portion 3, and 6 denotes cavities 7 respectively corresponding to the plurality of translucent bodies 4 and flanges formed by the edges of the cavities 7. A pressing plate that presses the edge of the portion 5 is a fastener that includes a screw rod that is erected on the upper surface of the plate body 2 and that is inserted into the pressing plate 6, and a nut that is screwed into the tip of the screw rod.

The conventional elevator car illumination device is constructed as described above, and the translucent body 4 is fitted into each of the openings 3 of the plate body 2 so that the edge portion of the flange portion 5 is an empty space of the pressing plate 6. It is arranged so as to face the edge of place 7. When the pressing plate 6 is fastened by the fastener 8, the edge of the flange portion 5 of the translucent body 4 is pressed against the edge of the cavity 7 of the pressing plate 6, so that the plurality of translucent bodies 4 together. It is fixed to the plate body 2.

[0004]

In the conventional lighting device for the elevator car as described above, since the plurality of translucent bodies 4 are fixed to the plate body 2 together, the pressing of the pressing plate 6 is uneven. In this case, there is a problem in that the transparent body 4 floats to generate noise due to the gap between the transparent body 4 and the opening 3 of the plate body 2, or the alignment lines are disturbed. In addition, there are problems that it takes a lot of time and effort to adjust the position of the translucent body 4 at a predetermined position, and that the side surface of the translucent body 4 hits the end face of the opening 3 and is damaged.

The present invention has been made in order to solve the above problems, and a lighting device for an elevator car in which a large number of light-transmitting bodies provided in the openings of the plate member are respectively held at the edges of the openings. Aim to get.

[0006]

In the lighting device for an elevator car according to the present invention, the elevator car illumination devices are arranged at positions corresponding to respective edges of the light-transmitting plane, and are provided at least at the edges of the upper surface of the flange of the light-transmitting body. An L-shaped mounting member to be engaged and a viscoelastic body interposed between the flange end surface and the mounting member are provided.

[0007]

In the illumination device for the elevator car configured as described above, the flange body end surface of the light transmitting body is pressed from the outer periphery by the viscoelastic body so that the light transmitting body is located at a predetermined position in the opening of the plate body. Retained.

[0008]

【Example】

Example 1. 1 and 2 are views showing an embodiment of the present invention, in which the same reference numerals as those in FIG. 4 indicate the corresponding parts, and 41 is a light-transmitting member which is provided in close contact with the upper surface of the light-transmitting member 4. 4 is a diffusing plate, 9 is a mounting bracket having an L-shaped cross section, one side 91 of the L-shape is horizontally arranged, the fastener 8 is inserted, and the flange portion 5 of the translucent body 4 is inserted. The other side 92 of the L-shape is overlapped with the edge portion of the upper surface and is vertically arranged to face the end surface of the flange portion 5. Reference numeral 10 denotes a viscoelastic body which is made of a sponge-like material such as rubber and is attached to the other side 92 of the attachment fitting 9 and faces the end surface of the flange portion 5.

In the elevator car lighting device constructed as described above, the translucent body 4 is fitted into the opening 3 of the plate body 2. Further, the viscoelastic body 10 is attached to the other side 92 of the mounting fitting 9.
Are bonded by an adhesive. Then, one side 91 of the mounting fitting 9 is inserted into the bolt of the fastener 8 to be in the state shown in FIG. When the nut is screwed into the fastener 8 in this state, the other side 92 of the mounting bracket 9 approaches the end surface of the flange portion 5, the viscoelastic body 10 is compressed and the state shown in FIG. 1 is reached, and the end surface of the flange portion 5 is pressed. To be done. Then, by disposing the fittings 9 provided with the viscoelastic body 10 at the edges facing each other with respect to the plane of the translucent body 4, the end surface of the flange portion 5 of the translucent body 4 is pressed from both sides. The translucent body 4 can be fixed at the central position of the opening 3 of the body 2. by this,
Due to the gap between the translucent body 4 and the opening 3 of the plate body 2, the translucent body 4
It is possible to solve the problems that noise occurs and noise is generated, and the arrangement lines are disturbed. Moreover, it takes time to adjust the light-transmitting body 4 at a predetermined position, and the end face of the opening 3 is not adjusted. It is possible to solve the problem that the side surface of the translucent body 4 hits and is damaged. Therefore, the translucent body 4 can be easily attached to the plate body 2 with good appearance.

Embodiment 2. FIG. 3 is a view showing another embodiment of the present invention. In the figure, the same reference numerals as those in FIGS. 1 and 2 indicate corresponding parts, and 9 shows an edge portion of the diffuser plate 41 on the upper surface of the light-transmitting body 4 extended. With a mounting member that is bent downward, one side 91 of the L-shape is horizontally arranged and the fastener 8 is inserted, and the other side 92 of the L-shape is vertically arranged to face the end surface of the flange portion 5. The viscoelastic body 10 is attached.

Also in the embodiment shown in FIG. 3, the end surface of the flange portion 5 of the transparent body 4 is pressed by the viscoelastic body 10. Therefore, although detailed description is omitted, it is apparent that the same operation as that of the embodiment of FIGS. 1 and 2 can be obtained in the embodiment of FIG. Further, in this embodiment, since the mounting member 9 is formed at the edge of the light diffusing plate 41, the number of parts is reduced, so that manufacturing and manufacturing control can be facilitated.

[0012]

As described above, according to the present invention, the light-transmitting body fitted in the opening of the plate and the light-transmitting body provided at the corresponding edge portions of the plane of the light-transmitting body are opposed to each other. An L-shaped mounting member that engages at least an edge portion of the upper surface of the flange portion and a viscoelastic body are provided between the end surface of the flange portion and the mounting member. Then, both sides of the end face of the flange of the translucent body are pressed from the outer periphery by the viscoelastic body, so that the translucent body is held at a predetermined position in the opening of the plate body. As a result, it is possible to eliminate the problems that the light-transmissive body floats or the alignment lines are disturbed due to the gap between the light-transmissive body and the opening of the plate body, and the light-transmissive body can be easily placed at a predetermined position. can do. Therefore, it is possible to assemble the lighting device in a good appearance with a small number of steps, and there is an effect of improving productivity.
