Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an elevator door device having a door main body that opens and closes a landing doorway or a car doorway.
[0002]
[Prior art]
In a conventional elevator door device, a shield plate having a U-shaped cross section is fixed to an entrance / exit frame. In addition, a shielding plate on the landing door side that faces the shielding plate on the entrance / exit frame side when the door is closed is fixed to the landing door. Further, a rubber plate that contacts the shielding plate on the landing door side when the door is closed is attached to the shielding plate on the entrance / exit frame side. Thereby, when the door is closed, the gap between the landing door and the entrance / exit frame is shielded, and smoke can be prevented from entering the hoistway from the landing (see, for example, Patent Document 1).
[0003]

Japanese Patent Laid-Open No. 7-157254
[Problems to be solved by the invention]
However, in the conventional door device, the rubber plate is attached to the inside of the U-shaped cross-section shielding plate fixed to the entrance / exit frame. Therefore, when it is necessary to replace the rubber plate due to wear, the landing door is obstructive. As a result, the workability of the replacement work is reduced.
[0005]
The present invention has been made to solve the above-described problems, and provides an elevator door device that can easily replace a seal member and improve the workability of maintenance work. The purpose is to obtain.
[0006]
[Means for Solving the Problems]
In the elevator door device according to the present invention, the upper smoke-shielding member having a groove extending in parallel with the entrance direction of the entrance is fixed to the upper frame of the entrance frame so as to face the upper portion of the door body, and when the door is closed. The mounting plate is fixed to the upper part of the door body so that it can be inserted into the groove, and the seal member that shields the gap between the upper smoke shield and the mounting plate contacts the inner wall surface of the groove when the door is closed. This is provided on the mounting plate.

[0023]
Further, since the seal members 10, 13, and 16 are provided on the mounting plates 9, 12, and 15 fixed to the door body 6, the inspection work and replacement work of the seal members 10, 13, and 16 can be easily performed. Thus, the workability of maintenance work can be improved.
[0024]
Embodiment 2. FIG.
Next, FIG. 4 is a cross-sectional view of an elevator landing door device according to Embodiment 2 of the present invention, and FIG. 5 is a cross-sectional view taken along the line VV of FIG. In FIG. 5, the illustration of the landing threshold 5 is omitted. In the drawing, the upper seal member is fixed to the first mounting surface 9a and contacts the first side wall surface 8b, and the second seal is fixed to the second mounting surface 9b and contacts the second side wall surface 8c. Member 21.
[0025]
The side seal member includes a first seal member 13 fixed to the first mounting surface 12a and contacting the first side wall surface 11b, and a second seal fixed to the second mounting surface 12b and contacting the second side wall surface 11c. Member 22.
[0026]
Furthermore, the lower seal member is fixed to the first mounting surface 15a and contacts the first side wall surface 14b, and the second seal member is fixed to the second mounting surface 15b and contacts the second side wall surface 14c. 23. That is, the seal members 10, 13, 16, 21, 22, 23 are provided on both surfaces of the mounting plates 9, 12, 15. Other configurations are the same as those in the first embodiment.
[0027]
In such a landing door device, since the seal members 10, 13, 16, 21, 22, and 23 are attached to both surfaces of the attachment plates 9, 12, and 15, the installation error of the door body 6 and the attachment plates 9 and 12 are eliminated. 15, even when the mounting plates 9, 12, 15 are inclined with respect to the grooves 8 a, 11 a, 14 a due to mounting errors or the like, at least one of the upper seal members 10, 21, the side seal member 13, At least one of 22 and at least one of the lower seal members 16 and 23 can be brought into contact with the smoke shielding members 8, 11, and 14, so that the smoke insulation and the sound insulation can be further improved.
[0028]
Embodiment 3 FIG.
6 is a cross-sectional view of an elevator landing door device according to Embodiment 3 of the present invention, and FIG. 7 is a cross-sectional view taken along line VII-VII in FIG. In FIG. 7, illustration of the landing threshold 5 is omitted. In this example, the fixing positions of the first and second seal members 10 and 21 in the depth direction of the groove 8a are shifted from each other. That is, the second seal member 21 is disposed on the landing side with respect to the first seal member 10.
[0029]
Further, the fixing positions of the first and second seal members 13 and 22 in the depth direction of the groove 11a are shifted from each other. That is, the second seal member 22 is disposed closer to the door pocket than the first seal member 13. Further, the fixing positions of the first and second seal members 16, 23 in the depth direction of the groove 14a are shifted from each other. That is, the second seal member 23 is disposed above the first seal member 16.
[0030]
Thus, the door main body 6 is obtained by shifting the fixing positions of the first and second seal members 10, 13, 16, 21, 21, and 23 in the depth direction of the grooves 8a, 11a, and 14a (staggered structure). Even when the mounting plates 9, 12, 15 are inclined with respect to the groove portions 8a, 11a, 14a due to the installation error of the mounting plate 9, the mounting plates 9, 12, 15 or the like, at least one of the upper seal members 10, 21 On the other hand, at least one of the side seal members 13 and 22 and at least one of the lower seal members 16 and 23 can be brought into contact with the smoke shielding members 8, 11, and 14. Can be further improved.
[0031]
In addition, in order to improve the slidability between the sealing member and the smoke shielding member, for example, a coating such as a fluorine coating or a molybdenum disulfide coating may be applied to at least one of the sealing member and the smoke shielding member.
In the above example, a separate seal member is fixed to the mounting plate, but the mounting plate and the sealing member may be integrated.
Furthermore, in the above example, the sill member is inserted into the sill groove, but the landing sill itself may be a sill member, and the sill groove may be a groove. That is, the lower seal member may contact the inner wall surface of the sill groove.
[0032]
Furthermore, although the center opening type door device is shown in the above example, the present invention can also be applied to a single opening type door device. Further, the number of door bodies is not limited to two.
In the above example, the landing door device is shown. However, the present invention can also be applied to a car door device, and the light shielding property and smoke shielding property between the car room and the outside can be improved.
[0033]
【The invention's effect】
As described above, in the elevator door device of the present invention, the upper smoke-shielding member having the groove extending in parallel with the entrance direction of the entrance is fixed to the upper frame of the entrance frame so as to face the upper part of the door body. The mounting plate is fixed to the upper part of the door body so as to be inserted into the groove when closed, and the sealing member that shields the gap between the upper smoke-shielding member and the mounting plate is used when the door is closed. Since the mounting plate is provided so as to be in contact with the inner wall surface, the seal member can be easily replaced, and the workability of maintenance work can be improved.
