Description

  Embodiments described herein relate generally to an elevator car interior mirror apparatus.

  A mirror is provided in the elevator car room for the convenience of wheelchair users. In order to prevent the safety of passengers from being lost due to the drop of the mirror, the mirror is subjected to multiple drop prevention measures. An example thereof is disclosed in Patent Document 1.

  In the car interior mirror apparatus described in Patent Document 1, a mounting plate having stud bolts (bolts attached by stud welding) on both left and right sides of a stainless steel reinforcing plate firmly bonded to the back surface of the mirror. Is attached with double-sided tape. The stud bolt is passed through a through hole provided in the wall of the cab, and the mounting plate is fixed to the wall by a nut that is screwed to the stud bolt.

  The car interior mirror device of Patent Document 1 is further provided with a drop-off prevention stud bolt or a drop-off prevention hook that is directly welded to the stainless steel reinforcing plate. The stud bolt for preventing the dropout is fixed to the wall of the cab with a nut. The hook for preventing the dropout is hooked on a member fixed to the wall of the cab. Such a drop-off prevention means prevents the mirror from falling off and ensures passenger safety even when the double-sided tape is peeled off due to poor installation during mirror installation or due to aging of the double-sided tape.

  The stainless steel reinforcing plate is heavy and causes deterioration of the installation of the mirror device. Since the reliability of the fall-off prevention structure by the stud bolt or hook depends on a firm weld joint between the stud bolt or hook and the reinforcing plate, it is difficult to eliminate the reinforcing plate.

  Hereinafter, various embodiments of a car interior mirror apparatus installed on a wall surface of an elevator car will be described with reference to the accompanying drawings. The car mirror apparatus is installed on the surface of the wall facing the car room on the side opposite to the car door (not shown).

  As shown in FIGS. 1A and 1B, the car interior mirror apparatus 1 is fixed to the wall 20 of the car room by screw fastening, and fixed to the mounting board 4 via a double-sided tape. The mirror 2 and a frame 3 that holds the peripheral edge of the mirror 2 are provided.

  FIG. 1A is a rear view of the mirror 2, the frame 3, and the mounting plate 4 as seen from the boundary surface between the wall body 20 and the frame 3. In FIG. 1A, the member behind the boundary surface is indicated by a virtual line (two-dot chain line) (FIGS. 4A, 5A, 6A, and 7A). The same applies to FIG. 8A). In FIG. 1B, the right side surface (the surface facing the car door) of each member in the drawing is referred to as the front surface, and the left side surface in the drawing is referred to as the back surface or the back surface (FIGS. 2, 3, and FIG. 4 (b), FIG. 5 (b), FIG. 6 (b), FIG. 7 (b), and FIG. 8 (b)).

  An anti-scattering film 6 is attached to the entire back surface of the mirror 2. The front surface of the mounting plate 4 and the back surface of the mirror 2 (specifically, the back surface of the anti-scattering film 6 attached to the back surface of the mirror 2) are joined to each other via a double-sided tape 5.

  A stud bolt 4 a is attached to the back surface of the mounting plate 4. The stud bolt 4a is joined to the mounting plate 4 by, for example, known stud welding. The stud bolt 4a is passed through a through hole formed in the wall 20 of the cab. The mounting plate 4 is firmly fixed to the wall body 20 by attaching (screwing) the nut 21 to the tip of the stud bolt 4a protruding to the back side of the wall body 20 and tightening the nut 21.

  A mirror receiving groove 3a is formed in the frame 3, and the peripheral edge of the mirror 2 is inserted into the mirror receiving groove 3a.

  Various embodiments of the car interior mirror apparatus disclosed in this specification have the above-described configuration in common. The car interior mirror apparatus further includes a frame support structure, and this frame support structure is different between the embodiments.

  The double-sided tape 5 may be peeled off from the mirror 2 (here, the anti-scattering film 6 affixed to the back surface of the mirror 2) or the mounting plate 4 due to deterioration over time or problems during installation. Even if such an event occurs, the frame support structure at least prevents the frame 3 from moving downward relative to the wall body 20 and prevents the mirror 2 from falling. The frame support structure is preferably configured to prevent the frame 3 from moving away from the wall 20 (forward).

As shown in FIGS. 1A and 1B, a plate receiving groove 7 that is concave upward is formed on the upper side of the frame 3. The plate receiving groove 7 is located on the back side with respect to the mirror receiving groove 3a. The frame support structure is configured by inserting the upper end of the mounting plate 4 into the plate receiving groove 7.

  When this configuration is adopted, some gap is formed between the back surface of the mounting plate 4 and the front surface of the wall body 20. For this reason, it is preferable to interpose the spacer 8 having a thickness corresponding to the gap between the mounting plate 4 and the wall body 20. Instead of providing the spacer 8, as shown in FIG. 2, the portion in the vicinity of the stud bolt 4a of the mounting plate 4 may be bent so as to be convex toward the wall body 20 side.

  According to the first embodiment, for example, as shown in FIG. 3, even if the double-sided tape 5 is peeled off from the mirror 2 or the mounting plate 4 due to deterioration over time or trouble during installation, it is firmly fixed to the wall body 20. The upper end portion of the mounting plate 4 continues to engage with the plate receiving groove 7 of the frame 3 to firmly support the frame 3. For this reason, the mirror 2 whose peripheral part is held by the frame 3 does not move downward. Further, the upper part of the frame 3 does not move in the direction away from the wall body 20 (forward). Therefore, the mirror 2 is not detached from the wall body 20 and falls into the car room.

  In addition, according to the first embodiment, since the stainless steel reinforcing plate 100 (see FIG. 8) bonded to the back surface of the mirror 2 is abolished, the overall weight of the car room mirror apparatus 1 can be reduced. Workability during transportation and installation is improved. Moreover, the material cost of the car mirror apparatus 1 can be reduced by eliminating the reinforcing plate 100 made of stainless steel.

One or more embedded screws 22 are embedded in the frame 3 on the back side of the upper side of the frame 3. In the embodiment shown in FIG. 4, two embedded screws 22 are provided at both left and right ends of the upper side of the frame 3. Each embedded screw 22 is passed through a mounting hole formed in the wall body 20. The frame 3 is fixed to the wall body 20 by attaching a nut 28 to the front end portion of each embedded screw 22 protruding to the back side of the wall body 20 and tightening the nut 28.

  According to the second embodiment, the frame 3 is firmly fixed to the wall body 20 by the embedded screw 22 and the nut 28. For this reason, even if peeling of the double-sided tape 5 occurs, the mirror 2 does not move and does not fall.

[Third Embodiment]
A frame support structure provided in the car interior mirror apparatus 1 according to the third embodiment will be described with reference to FIG. A hook 23 provided integrally with the frame 3 is provided at the center of the upper side of the frame 3. The hook 23 may be formed separately from the frame 3 and then joined to the frame 3, or the hook 23 and the frame 3 may be formed integrally.

  A hook hole 29 into which the hook 23 is inserted is formed in the wall body 20. When the hook 23 is attached to the hook hole 29, the root portion 23 b of the hook rides on the bottom surfaces 29 b on both sides of the hook hole 29, and prevents the frame 3 from moving downward with respect to the wall body 20. At this time, the lower end portion of the distal end portion 23 a of the hook 23 is in contact with the back surface of the wall body 20 while being positioned below the bottom surface 29 a of the central portion of the hook hole 29, and forward so that the frame 3 is separated from the wall body 20. Prevent moving.
