When the above mechanism is adopted, for example, a bolt or the like is used as an adjustment mechanism for adjusting the position of the second facing surface 25b.

[0045] By having a powerful configuration, the heat insulating material 6 can be reliably fixed with a simple configuration even when the door thickness of the door panel 22 is different on both sides, as in the third and fourth embodiments. Other configurations and effects are the same as those in the first embodiment.

[0046] Embodiment 6.

FIG. 10 is a cross-sectional view taken along the line DD of FIG. 1 in Embodiment 6 of the present invention. In FIG. 10, reference numeral 26 denotes a fixing member provided at the lower end portion of the front surface portion 11 of the door panel 5, and is disposed below the heat insulating material 6 disposed on the back side of the front surface portion 11 of the opening portion 16 force door panel 5. . The fixing member 26 has a predetermined gap from the hoistway side to a part of the first opposing surface 26a that comes into contact with the lower end surface 6c of the heat insulating material 6 so that the downward force also opposes the lower end portion of the rear surface 6a of the heat insulating material 6. And a second opposing surface 26b facing each other, for example, a plate-like member having a substantially Z-shape in side view.

[0047] According to the sixth embodiment of the present invention, the vertical displacement of the heat insulating material 6 with respect to the door panel 5 is constrained with a simple configuration and the large opening 16 formed on the back side of the door panel 5. Is possible. Other configurations are the same as those in any of Embodiments 1 to 5. It has composition and effect.

[0048] Embodiment 7.

FIG. 11 is a sectional view taken along the line DD of FIG. 1 in the seventh embodiment of the present invention. In FIG. 11, 27 is a first fixing member having a substantially Z-shape in a side view provided on the lower part of the other side surface of the front surface portion 11 of the door panel 5, and 28 is the first fixing member on the hoistway side from the heat insulating material 6. This is a second fixing member that is fixed to the fixing member 27 and has a substantially L-shape in a plan view and is extended to the surface portion 11 side so that the tip portion does not contact the other side surface of the surface portion 11. The first fixing member 27 and the second fixing member 28 constitute the fixing member 26 in Embodiment 6, and the first facing surface 26a and the second fixing member 26 are formed on a part of the second fixing member 28. The opposite surface 26b is formed. Further, the first fixing member 27 is provided so as not to contact the heat insulating material 6.

[0049] By having a powerful configuration, heat from the surface portion 11 can be prevented from being directly transmitted to the second fixing member 28 on which the first facing surface 26a is formed, and the heat insulation is further improved. It becomes possible. The other configurations and effects are the same as those of the sixth embodiment.

Industrial applicability

[0050] As described above, according to the elevator landing door device that is effective in the present invention, the opening is formed on the back surface of the landing door so that the heat insulating material provided inside the door panel directly faces the hoistway. Therefore, it is possible to suppress the temperature rise on the back surface of the landing door and improve the heat insulation.

Further, since the heat insulating material can be easily and reliably fixed by the fixing member having a predetermined shape, the structure can be simplified and the assemblability can be improved.
