Description

  Embodiments of the present invention relate to an elevator hall display device.

  A hall display device including an operation push button, an indicator light, an indicator, and the like is installed in a hall of an elevator. When the user at the hall presses the operation push button, the hall call is registered and the operation push button lights up. The indicator displays the current position and direction of the car. Since such a hall display device is installed on the wall surface of a hall, there are various things to be considered in mounting.

  On the walls of the elevator hall, paint, mortar, finishing materials, etc. are piled up on the concrete base. Depending on the finish of the construction, the surface of the base may have an irregular surface with unevenness. In addition, due to poor finishing, the hall display device may be mounted in an inclined state. For this reason, various measures have been taken in the past in order to prevent problems in mounting the hall display device due to incomplete construction.

For example, Patent Document 1 proposes a hall display device in which the housing of the hall display device can be attached without distortion even when the wall surface is an irregular surface having irregularities.
Further, Patent Document 2 proposes a hall display device including a mechanism capable of adjusting the inclination of the face plate even when the housing of the hall display device is attached in a tilted state.

Japanese Patent No. 3807828 JP, 2013-220881, A

The hall display device of the elevator may be attached after the wall finishing work of the hall is completed, but is often attached before the wall finishing work or while the wall finishing work is in progress. This is to ensure the use of the elevator. For this reason, the hall display device needs to be attached in such a state that the dimension corresponding to the finish of the wall is floated from the wall.
However, if there is a hall display device in a floating state, it is very difficult to finish the wall around the hall display device, and it is difficult to finish it to high quality.
On the other hand, wall finishing is a skill that requires skill, such as correcting irregularities on the surface of the base and applying mortar to multiple layers. The finish of the wall often depends on the ability of the individual craftsman. For this reason, unevenness remains on the finished surface of the wall, the thickness is not constant, and the finished surface is uneven. The finish of the wall has a great influence on the quality of the mounting condition of the hall display device.

  When the wall is incompletely finished, the hall display device housing may not be in close contact with the finished surface of the wall. Around the housing of the hall display device, there is a problem that a gap is formed between the housing and the wall surface, and the housing tilts. In some cases, it was necessary to remove the hall display and refinish the wall.

  The present invention has been made in view of the above-mentioned problems of the prior art, and the hall display device can be attached without hindering the progress of the wall finishing work and being unaffected by the finish of the wall. It is an object of the present invention to provide a hall display device for such an elevator.

Hereinafter, an embodiment of an elevator hall display device according to the present invention will be described with reference to the accompanying drawings.
(First embodiment)
FIG. 1 is a perspective view showing an entire elevator hall display device according to a first embodiment of the present invention. In FIG. 1, reference numeral 20 indicates a hall display device. Reference numeral 21 is a housing forming the main body of the hall display device. In this embodiment, the housing 21 is provided with car call buttons 23a and 23b for performing car call registration operation, and an indicator 24 indicating the direction of the car and the floor on which the car is located. .. The housing 21 houses the main bodies of the car call buttons 23a and 23b, the indicator 24, and the electric circuits connected to these.

  Next, in FIG. 1, reference numeral 10 indicates a wall mounting plate. The wall surface mounting plate 10 is a plate that is fixed to a ground such as concrete on the hall wall surface. In this embodiment, the housing 21 is supported by a plurality of bolts so as to float from the base of the wall surface.

Next, FIG. 2 is a perspective view showing the configuration of the wall surface mounting plate 10. The wall surface mounting plate 10 is a plate-shaped member that is slightly smaller than the housing 21 shown in FIG. Screws 11 are screwed into the upper and lower end portions and the central portion of the wall surface mounting plate 10, and the wall surface mounting plate 10 is fixed to the base of the wall surface. A plurality of nuts 12 are fixed to the wall mounting plate 10 at required positions.
Here, FIG. 3 is a perspective view showing the intermediate mounting bracket 16 whose position is adjustable by a bolt 14 screwed into the nut 12.
The intermediate mounting bracket 16 is a rectangular member that is slightly larger than the wall mounting plate 10. The back surface side of the intermediate mounting bracket 16 is formed in a generally concave shape. The head 15 of the bolt 14 is exposed on the surface of the intermediate mounting bracket 16.

FIG. 4 is a view showing a cross section of the wall surface mounting plate 10 and the intermediate mounting bracket 16.
The bolt 14 screwed into the nut 12 extends through the wall mounting plate 10 to the hole drilled in the concrete underlayer 17. In FIG. 4, A indicates the distance between the base 17 and the intermediate mounting bracket 16.

  When the bolt 14 is turned in the direction in which it is tightened in the nut 12, the intermediate mounting bracket 16 approaches the base 17, so that the distance A between the intermediate mounting bracket 16 and the surface of the base 17 can be narrowed. .. By rotating the bolt 14 in the opposite direction, the distance A between the intermediate mounting bracket 16 and the surface of the base 17 can be lengthened. As described above, in the present embodiment, means for supporting the intermediate mounting bracket 16 while variably adjusting the distance A between the base 17 and the intermediate mounting bracket 16 from the bolt 14 and the nut 12 is configured.

  In FIG. 4, the housing 21 of the hall display device 20 is mounted so as to be fitted to the intermediate mounting bracket 16, and is fixed by a fastening member such as a screw (not shown). As a result, the housing 21 is supported by the bolts 14 in a state of being floated from the base 17 of the wall surface.

  Since the elevator hall display device according to the present embodiment is supported by the bolts 14 and the intermediate mounting brackets 16 as described above, the finishing of the wall surface can be performed as follows.

  FIG. 5 is a diagram showing the position of the intermediate mounting bracket 16 when performing finish construction on the wall surface. The housing 21 of the hall display device 20 is attached to the intermediate mounting bracket 16 before or during the finishing work, and the elevator is ready to be used by using the hall display device 20. A space sufficient for finishing work is secured between the wall surface base 17 and the intermediate mounting bracket 16. Therefore, the casing 21 does not hinder the finishing work.

Next, FIG. 6 is a diagram showing the position of the intermediate mounting bracket 16 when the finishing of the wall surface is completed.
As the bolt 14 is turned in the tightening direction, the distance between the wall finishing material 30 and the intermediate mounting bracket 16 becomes narrower. Further, as the bolt 14 is tightened, the convex portion 18 of the intermediate mounting bracket 16 comes into contact with the surface of the finishing material 30. In this case, the end face of the housing 21 is adjusted so as to come into contact with the finishing material 30 at the same time when the convex portion 18 comes into contact, so that the housing 21 can be brought into close contact with the finishing material 30 without a gap. Further, even if the thickness of the finishing material 30 is not completely uniform and there is some variation or unevenness, by tightening the bolt 14, the housing 21 is mounted without a gap between the housing 21 and the finishing material 30. Therefore, it is possible to avoid the influence of the quality of the finish.
The above is the case where the finishing material 30 is relatively thick.

  Next, FIG. 7 and FIG. 8 are views showing an example of construction in the case where the finishing material 32 on the wall surface is very thin. Of these, FIG. 7 shows the position of the intermediate mounting bracket 16 during wall finishing, and FIG. 8 shows the position of the intermediate mounting bracket 16 after completion of wall finishing.

  In this case, since the thickness of the finishing material 32 is thin, a very large space is not required between the underlayer 17 of the wall surface and the intermediate mounting bracket 16 to perform the finishing work. The adjustment of this interval is performed by rotating the bolt 14. As shown in FIG. 7, an appropriate space is secured for construction, but since the finishing material 32 is thin, the housing 21 does not hinder the finishing work.

  When the finishing of the wall surface is completed, the bolt 14 is turned in the tightening direction, and as shown in FIG. 8, the intermediate mounting bracket 16 is brought closer to the finishing material 32 of the wall surface. Further, as the bolt 14 is tightened, the convex portion 18 of the intermediate mounting bracket 16 comes into contact with the surface of the finishing material 32. Since the end face of the housing 21 is adjusted to come into contact with the finishing material 32 simultaneously with the contact of the convex portion 18, the housing 21 can be brought into close contact with the finishing material 32 without a gap. Further, even if the thickness of the finishing material 32 is not completely uniform and there is some variation or unevenness, by tightening the bolt 14, the housing 21 is mounted without a gap between the finishing material 32 and the finishing material 32. be able to.

  The thickness of this finishing material 32 is very thin. In this embodiment, since the intermediate mounting bracket 16 is formed with the recess 19 capable of accommodating the wall surface mounting plate 10 and the nut 12 by embossing, the nut 12 does not interfere even with the thin finishing material 32. It is possible to mount the housing 21 without any gap between the housing 21 and the finishing material 32.

  As described above, even in the case of the thick finishing material 30 (FIG. 6) and the thin finishing material 32 (FIG. 8), the wall finish construction is hindered by the hall display device 20 without considering the thickness. Can be implemented without

(Second embodiment)
Next, an elevator hall display device according to a second embodiment of the present invention will be described with reference to FIG.
FIG. 9 is an exploded perspective view of the hall display device 20 according to the second embodiment of the present invention. The second embodiment is an embodiment in which a protection tube 40 is added to cover the bolt 14. The same components as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

  The protective tube 40 is a flexible tube, such as a resin tube, a rubber tube, or a bellows tube, which is buckled when a predetermined axial force is applied. The length of the protection tube 40 is set shorter than the length of the bolt 14. The bolt 14 is inserted into the protective tube 40, and the protective tube 40 is arranged between the wall surface mounting plate 10 and the intermediate mounting bracket 16 in this state.

  According to the second embodiment as described above, the protective tube 40 protects the bolt 14 from the paint or the like when the paint or the like is sprayed in the finishing process of the wall surface. That is, it prevents the paint or the like from adhering to the male screw of the bolt 14. Therefore, when the wall surface is finished and the housing 21 is attached in close contact with the wall surface, the bolts 14 can be smoothly tightened. Further, in the case of the thin wall finishing material 32 as shown in FIG. 8, the protective flexible tube 40 buckles, so the bolts 14 can be tightened and the housing 21 can be attached.

(Third Embodiment)
FIG. 10 shows an elevator hall display device according to a third embodiment of the present invention.

  In the first and second embodiments, a screw mechanism composed of bolts and nuts is adopted as a means for movably supporting the intermediate mounting bracket 16 to which the housing 21 is attached, but in the third embodiment, Instead of the screw mechanism, the following parallel link mechanism is adopted.

  In FIG. 10, reference numerals 44a and 44b are mutually parallel link members that connect the wall surface mounting plate 10 and the intermediate mounting bracket 16. One ends of the link members 44a and 44b are connected to the slide members 45a and 45b, and the slide members 45a and 45b are guided in the longitudinal direction of the wall mounting plate 10 by the guides 48a and 48b.

Here, FIG. 11 is a side view of the parallel link mechanism.
One end of the link member 44a is connected to the slide member 45a via a pin 46a, and the other end of the link member 44a is connected to the intermediate mounting bracket 16 via a pin 46a. The other link member 44b has a similar connection structure, which is not shown in FIG.
In FIG. 11, the intermediate mounting bracket 16 is shown in a position farthest from the wall mounting plate 10. FIG. 12 shows the intermediate mounting bracket 16 that has moved closer to the wall surface mounting plate 10 by moving the slide member 45a. In this way, by moving the slide members 45a and 45b along the guides 48a and 48b, the distance between the wall surface mounting plate 10 and the intermediate mounting bracket 16 can be made variable.

In the above-described third embodiment, when the wall finishing work is performed, as shown in FIG. 11, the intermediate mounting bracket 16 is located away from the wall surface mounting plate 10 and the wall finishing work is performed. .. Since the link members 44a and 44b contact stoppers (not shown), the housing 21 attached to the intermediate mounting bracket 16 is supported.
When the wall finishing work is completed, the housings 21 can be brought into close contact with the wall finishing material (not shown) in the same manner as in the first embodiment by moving the slide members 45a and 45b.
