Return to Fig. 1, the left door 50, together with the right door 40 described above, constitutes the door structure for closing the opening 33a of the housing 30, the left door 50 closing a left side portion of the opening 33a. Next, a detailed configuration of the left door 50 above will be described.
Fig. 4 is a configuration diagram of the left door 50 of the housing accommodating the hall device of the elevator according to the embodiment, including the front view 1A, the top view 1B corresponding to the front view 1A, the side view 1C, and the main part enlarged view 1D of the left door 50. The front view 1A corresponds to a diagram of the left door 50 viewed from the traveling path, and the main part enlarged view 1D corresponds to the enlarged view of the part D in the top view 1B. Fig. 5 is a perspective view for explaining the left door 50 of the housing accommodating the hall device of the elevator according to the embodiment and is an enlarged perspective view of a part E in Fig. 4. In this perspective view, a part of the housing 30 is also illustrated for the sake of explanation. As illustrated in Figs. 4 and 5, the left door 50 is a plate-like member including a left front panel 51, a left support part 52, and a left engagement part 53. Each of these parts will be described below.

The left front panel 51 is a portion disposed to close the opening 33a between the top surface 31 and the bottom surface 32 of the housing 30, and is a plate-like portion having a substantially rectangular shape. A height [H2] of the left front panel 51' is a height exceeding the opening width of the opening 33a in the height direction, and is a size that does not overlap the hall door 10 (refer to Fig. 1) in a state where the opening 33a is closed by the left door 50.
The right edge of the left front panel 51 is disposed so as to overlap the left edge of the right front panel 41 of the right door 40 described above (refer to Fig. 2), and forms the meeting stile of the door structure including the right door 40 and the left door 50. Therefore, a width [W2] of the left front panel 51 is a size that the opening 33a of the housing 30 is closed by the right front panel 41 of the right door 40 and the left front panel 51 that are provided with the meeting stile and disposed.

The left support part 52 is a portion that is disposed to overlap the top surface 31 of the housing 30 and by which the left door 50 is supported on the housing 30. The left support part 52 above is a plate-like portion provided by bending the upper end of the left front panel 51 in the height direction in one direction, and has at least two keyholes 52a for fixing the left door 50 to the housing 30. These keyholes 52a are provided at positions corresponding to screw holes provided in the top surface 31 of the housing 30. The keyholes 52a above have a configuration in which a long diameter portion 52aa is arranged in a state of extending along a boundary direction between the left front panel 51 and the left support part 52, and a large diameter portion 52ab is arranged on the right side (the side on the meeting stile) of the long diameter portion 52aa.
In addition, a protrusion length [D2] of the left support part 52 from the left front panel 51 is a size that enables the left support part 52 overlapped on the top surface 31 of the housing 30 to support the entire portion of the left door 50 including the left support part 52 and is sufficient to provide the keyholes 52a. However, the protrusion length [D2] of the left support part 52 from the left front panel 51 is longer than the protrusion length [D1] (refer to Figs. 2 and 3) of the right support part 42 of the right door 40 described above by a protrusion length [L2] of the left engagement part 53 described next.
Note that the left support part 52 is also a roof part that covers the opening 33a of the housing 30, and may be provided continuously above the opening 33a, and does not need to have the protrusion length [D2] in all the continuous portions. In particular, the left door 50 has, at its right end, a left notch 52b in which the left support part 52 is not provided, and in the left notch 52b, the left front panel 51 protrudes to the right end than the left support part 52 does. The left notch 52b serves as a fitting part to the right door 40 described above with reference to Figs. 2 and 3. A width [C2] of the left notch 52b above is not particularly limited, but is a size that enables a space sufficient to retain liquid water to be formed between the left notch and the left door 50 described next.

The left engagement part 53 is a portion that becomes a connection part with respect to the right door 40 (refer to Fig. 1) described above, with the space described later. The left engagement part 53 above is a plate-like portion provided by being bent from the right edge of the left front panel 51 toward the same side as the left support part 52, having a predetermined protrusion length [L2] from the left front panel 51. The protrusion length [L2] is substantially the same as the protrusion length [L1] of the right engagement part 43 of the right door 40, and this configuration makes the space formed by the right door 40 and the left door 50 a closed space.
Here, the left engagement part 53 is a plate-like portion provided by bending the right edge of the left front panel 51 toward the same side as the left support part 52. Therefore, in manufacturing the left door 50, a gap 50a is generated, being formed between an upper part of the left engagement part 53 to the left front panel 51 and the left support part 52. The gap 50a is generated corresponding to the width [C2] of the left notch 52b of the left support part 52 at an end of the left front panel 51.

<<Closing Procedure of Housing and Door Structure>>

Next, a closing procedure of the housing 30 by the right door 40 and the left door 50, which have already been described with reference to Figs. 2 to 5, and a door structure will be described. Figs. 7 and 6 are the diagrams (I) and (II) for explaining the closing procedure of the housing accommodating the hall device of the elevator according to the embodiment. Hereinafter, the closing procedure of the housing accommodating the hall device of the elevator and the door structure will be described with reference to Fig. 3 above and Figs. 6 and 7.
First, as illustrated in Fig. 3, the right side portion of the opening 33a of the housing 30 is closed by the right door 40. At this time, the right support part 42 of the right door 40 is disposed so as to be overlapped on the top surface 31 of the housing 30. Then, among the bolts 34 fastened to the top surface 31 of the housing 30, the two bolts 34r disposed on the right side as viewed from the front are fit to the two keyholes 42a (only two are illustrated in Fig. 3) provided in the right support part 42 of the right door 40. Thus, in a state where the right door 40 is supported on the housing 30 by the right support part 42 overlapped on the top surface 31 of the housing 30, the right side portion of the opening 33a of the housing 30 is closed by the right front panel 41.
Next, as illustrated in Fig. 6, the left side portion of the opening 33a of the housing 30 is closed by the left door 50. At this time, the left support part 52 of the left door 50 is overlapped on the top surface 31 of the housing 30, and the left door 50 is disposed so that the right engagement part 43 of the right door 40 is covered with the left front panel 51 and the left engagement part 53 of the left door 50. Then, among the bolts 34 fastened to the top surface 31 of the housing 30, the two bolts 341 disposed on the left side as viewed from the front are fit to the two keyholes 52a (only two are illustrated in Fig. 6) provided in the left support part 52 of the left door 50. Thus, in a state where the left door 50 is supported on the housing 30 by the left support part 52 overlapped on the top surface 31 of the housing 30, the left side portion of the opening 33a of the housing 30 is closed by the left front panel 51. In addition, the right engagement part 43 of the right door 40 and the left engagement part 53 of the left door 50 are disposed facing each other through a space [S].
Thereafter, as illustrated in Fig. 7, the right door 40 is slid to the left along the keyholes 42a, the left door 50 is slid to the right along the keyholes 52a, and an edge of the right support part 42 of the right door 40 and an edge of the left support part 52 of the left door 50 are come into contact with each other. Thus, entry of liquid water from the gap between the right support part 42 and the left support part 52 is restrained. In this state, at the long diameter portions 42aa of the keyholes 42a of the right door 40, the right support part 42 of the right door 40 is fastened to the top surface 31 of the housing 30 by the bolts 34. In addition, in this state, at the long diameter portions 52aa of the keyholes 52a of the left door 50, the left support part 52 of the left door 50 is fastened to the top surface 31 of the housing 30 by the bolts 34.
As stated above, the opening 33a of the housing 30 is closed by the right door 40 and the left door 50. The door structure above including the right door 40 and the left door 50 forms a meeting stile [M] in which the left edge of the right front,panel 41 of the right door 40 and the right edge of the left front panel 51 of the left door 50 are disposed at positions overlapping each other in the front-rear direction with the space [S].
In addition, the right engagement part 43 of the right door 40 and the left engagement part.53 of the left door 50 form connection parts overlapping each other in the right and left direction with the space [S], so that the space [S] is surrounded from four directions. Moreover, this door structure has a configuration in which an upper part of the space [S] in the meeting stile [M] is closed by the left support part 52 of the left door 50.
Furthermore, the gap 50a between the upper part from the left engagement part 53 to the left front panel 51 and the left support part 52 is provided facing the space [S].

<<Effects of Embodiments

With the embodiment described above, the meeting stile [M] configured to close the opening 33a of the housing 30, in which the right door 40 and the left door 50 overlap each other, has a meeting stile structure with the space [S] that is closed from four directions and the top surface of which is closed. As a result, a water droplet from above is less likely to enter the meeting stile [M] between the right door 40 and the left door 50, and even if the water droplet enters the meeting stile [M], the water droplet is held in the space [S], and it is possible to effectively prevent the water droplet from entering the hall device 20 in the housing 30. Therefore, it is possible to prevent deterioration of the hall device 20 in the housing 30 due to liquid water.
In addition, the right door 40 and the left door 50 can be easily aligned by fitting the bolts 35 to the keyholes 42a and 52a. Moreover, because of the configuration in which the right door 40 is supported on and fixed to the housing 30 in the right support part 42 and the left door 50 is supported on and fixed to the housing 30 in the left support part 52, the housing 30 can be closed without requiring a delicate operation.
Note that the present invention is not limited to the above-described embodiment and modifications, and further includes various modifications. For example, the above-described embodiment is described in detail in order to describe the present invention in an easy-to-understand manner, and is not necessarily limited to those having all the described configurations. In addition, a part of configurations of an embodiment can be replaced with a configuration of another embodiment, and a configuration of another embodiment can be added to a configuration of a certain embodiment. In addition, it is also possible to add, delete, and replace other configurations for a part of a configuration of each embodiment.
