DETAILED DESCRIPTION OF THE INVENTION
First Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a first embodiment of an elevator car interior mirror apparatus according to the present invention.
[0011]
As shown in FIG. 1, an elevator car interior mirror apparatus 1 is installed on a wall surface of an elevator car room 20. The mirror device 1 includes a mirror 1a, a stainless steel reinforcing plate 2 bonded to the back surface of the mirror 1a, and a frame 3 that holds the mirror 1a. The four corners of the frame 3 are abutted and joined.
[0012]
A mounting plate 4 having embedded screws 4 a is fixed to the back surface of the stainless steel reinforcing plate 2 with a double-sided tape 5.
[0013]
A mounting screw (drop-off prevention tool) 10 is fixed to the stainless steel reinforcing plate 2 provided on the back surface of the mirror 1a by welding.
[0014]
Next, the operation of the present embodiment having such a configuration will be described.
[0015]
First, the embedded screw 4a of the mounting plate 4 and the welded mounting screw 10 are aligned with the through-hole provided in the wall surface of the elevator cab 20 to penetrate the wall surface.
[0016]
Next, the nut 21 is fastened to the embedded screw 4 a and the mounting screw 10 from behind the side plate on the wall surface of the cab 20, and the mirror 1 a is attached to the wall surface of the cab 20. Should the double-sided tape 5 that joins the mounting plate 4 with the embedded screw 4a peel off due to aging or insufficient pasting accuracy, the welded mounting screw 10 will attach the mirror 1a to the wall of the cab 20 Fix it. For this reason, the mirror 1a does not fall off the floor of the elevator cab 20. For this reason, a safe elevator can be provided. Furthermore, there is no need to place the embedded screw 4a or the mounting screw 10 on the peripheral edge of the mirror 1a, and there is no need to provide a hairline for the mirror 1a.
[0017]
Second embodiment of the present invention Next, a second embodiment of the present invention will be described with reference to FIG. The second embodiment shown in FIG. 2 is different from the first embodiment shown in FIG. 1 except for the configuration of the drop-off prevention device.
[0018]
As shown in FIG. 2, a mounting plate 4 having embedded screws 4 a is joined to the back of a stainless steel reinforcing plate 2 provided on the back surface of the mirror 1 a by a double-sided tape 5. Further, an additional mounting plate (falling prevention tool) 6 having mounting screws 6a is joined to the reinforcing plate 2 by spot welding.
[0019]
In FIG. 2, even if the double-sided tape 5 is peeled off due to aging or insufficient pasting accuracy, the mounting screw 6a of the mounting plate 6 penetrates the wall surface of the elevator cab 20 and is fastened by the nut 21. The mirror 1a does not drop out on the floor of the cab 20 and a safe elevator can be provided.
[0020]
Third embodiment of the present invention Next, a third embodiment of the present invention will be described with reference to FIG. The third embodiment shown in FIG. 3 is different from the third embodiment only in that a drop-off prevention tool including a hook 7 and a holding plate 9 having a mounting screw 9a is provided instead of the mounting screw 10. 1 is substantially the same as the first embodiment shown in FIG.
[0021]
As shown in FIGS. 3 (a) and 3 (b), a mounting plate 4 having an embedded screw 4a is joined to the back of a stainless steel reinforcing plate 2 provided on the back surface of the mirror 1a by a double-sided tape 5 (see FIG. 1). In addition, a hook 7 is joined to the stainless steel reinforcing plate 2 provided on the back surface of the mirror 1a by spot welding. Then, the mounting screw 9 a of the holding plate 9 is inserted into the groove of the hook 7.
[0022]
3 (a) and 3 (b), the embedded screw 4a and the mounting screw 9a are inserted into the through-holes on the back surface of the elevator cab 20, and the embedded screw 4a and the mounting screw 9a have a nut 21 (FIG. 1 (b)). )) Is fastened and the mirror 1a is held. Since the holding plate 9 having the hook 7 and the mounting screw 9a is a thin plate, it can be appropriately disposed on the back side of the mirror 1a even when the step of the frame 3 is small.
[0023]
3A and 3B, even if the double-sided tape 5 is peeled off due to aging or pasting accuracy, the holding plate 9 having the mounting screw 9a is caught on the hook 7, so that the mirror 1a is in the elevator cab 20. A safe elevator can be provided without falling off the floor.
[0024]
As shown in FIGS. 3C and 3D, the hook 7 may be formed in a side trapezoidal shape, the pressing plate 9 may be formed in a square shape, and the pressing plate 9 may be inserted into the hook. In this case, even if the mounting screw 9a of the presser plate 9 is fastened by the nut 21 from behind the wall surface of the cab 20, the presser plate 9 is not caught and rotated, and the nut 21 can be easily tightened.
[0025]
【The invention's effect】
As described above, according to the present invention, the mirror is fixed to the wall surface of the car room not only by the mounting plate having the embedded screw but also by the drop-off prevention tool. Therefore, the mirror can be prevented from falling off and a safe elevator can be provided. In addition, since the drop-off prevention tool can be freely arranged on the back surface of the mirror, it is not necessary to treat the mirror surface with a hairline or the like.
