Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a double deck elevator in which an air conditioning member is provided on an opening / closing door of a lower car.
[0002]
[Prior art]
In general, a traction type double deck elevator is configured as shown in FIG.
[0003]
That is, the car 1 is composed of a car frame 2 and an upper car 31 and a lower car 32 mounted up and down in the car frame 2, and a pair of guide rails 51 erected in the hoistway 4. It moves up and down as guided by 52.
[0004]
The car frame 2 is fixed between an upper beam 21 and a lower beam 22, vertical frames 23 and 23 fixed at both left and right ends of the upper and lower beams 21 and 22, and an intermediate portion of the vertical frames 23 and 23. The car 1 is connected to a main rope 6 suspended from a hoisting machine (not shown) via a hitch plate 25 provided on the upper beam 21.
[0005]
The upper car 31 and the lower car 32 in the car frame 2 are placed on the intermediate beam 24 and the lower beam 22 via floor receiving frames 26 and 26 and vibration isolating rubbers 27 and 27, respectively.
[0006]
The compensation beam 7 is connected between the lower beam 22 and a counterweight (not shown), and a tail cord 8 for transmitting electric power, a control signal and the like from an elevator control device (not shown) to the car 1 is connected. ing.
[0007]
FIG. 8 shows the configuration of the main part of the connecting portion on the doorway side between the upper car 31 and the lower car 32 in the double deck elevator.
[0008]
As shown in FIG. 8, a plate-like apron (apron) is provided below the open / close door 311 of the upper car 31, that is, at the lower part of the sill 311a, in order to protect the feet of passengers getting on and off the upper car 31. 312 is mounted vertically downwards.
[0009]
On the other hand, on the open / close door 321 of the lower car 32, an air-conditioning member 322 made of an air-conditioning plate is erected and attached, and the air-conditioning member 322 and the apron 312 are connected via a cushioning material 33 such as synthetic rubber. Has been.
[0010]
In the double deck elevator, when the passengers get in and out of the upper and lower cars 31 and 32, the car load changes and moves up and down, so the distance between the cars 31 and 32 also varies slightly. The fluctuation is absorbed so that a large load is not applied to the apron 312 and the air conditioning member 322.
[0011]
[Problems to be solved by the invention]
As described above, in the conventional double deck elevator car, the cushioning material 33 absorbs the change in the distance between the upper and lower cars 31 and 32 due to the change in the car load when the passenger gets on and off, and the upper and lower cars 31 and 32. The apron 312 and the air conditioning member 322, which are fixed to each other, are configured not to be subjected to excessive stress.
[0012]
However, in a building or the like where a dub deck elevator is installed, the floor height of the landing may vary depending on the floor due to the structure.
[0013]
When the floor height varies depending on the floor, the upper and lower cars 31 and 32 cannot be landed at the same time and opened with the distance between the upper and lower cars 31 and 32 kept constant.
[0014]
Therefore, in such a case, the upper and lower cars 31 and 32 are individually landed at different timings, or on the car 1 side, so-called floor adjustment that changes the interval between the upper and lower cars 31 and 32 is performed. The landing door is opened after adjusting to the height. From the viewpoint of increasing the operation efficiency of the elevator, the latter is often used to adjust the floor on the side of the car 1.
[0015]
However, as shown in FIG. 8, in the double deck elevator having a structure in which the apron 312 and the air conditioning member 322, both of which are plate-like, are connected and fixed via the cushioning material 33, the distance between the upper and lower cars 31 and 32 is increased. Since it cannot be changed, normally, a cushioning material 33 is removed, and a wide gap is provided in advance between the apron 312 and the air conditioning plate 322 so as not to collide with each other.
[0016]
If there is a gap between the apron 311 and the air conditioning member 322, the airflow generated when the car 1 travels passes through the gap to generate a so-called wind noise, which is generated as noise by each car 31, It was transmitted to the inside 32 and became a factor which disturbed comfortable riding comfort.
[0017]
Therefore, the present invention provides a double deck elevator that can suppress the generation of wind noise and can be used comfortably by users even when floor adjustment is performed on the car side. Objective.
[0018]
[Means for Solving the Problems]
The present invention has been made to solve the above-described conventional problems, and has an upper and lower car chambers, and an apron suspended from the lower part of the upper car door is erected on the upper part of the lower car door. In the double deck elevator connected to the air conditioning member, the air conditioning member is configured such that its length is freely extendable in the vertical direction, and is extended and contracted by being guided by a guide member connected and fixed to the upper car or the lower car. It was configured as described above .
[0019]
In this way, by configuring the air conditioning member so that it can be expanded and contracted in the vertical direction, the vertical length of the air conditioning member itself changes corresponding to the adjustment of the floor between the upper and lower cars, and between the air conditioning member and the apron. As a result, no noise is generated due to wind noise or the like.
[0020]
Further, the present invention is a double deck elevator having a car room at the top and bottom, and having an apron that is suspended from the lower part of the upper car door and an air conditioning plate that is erected at the upper part of the lower car door. The air conditioning plate and the apron have overlapping portions in the front-rear direction, and are configured to be relatively vertically moved by being guided by a guide member connected and fixed to an upper car or a lower car. And
[0021]
In this way, the wind regulation plate and the apron have overlapping portions in the front-rear direction, and are configured so that they can be relatively moved up and down while being guided by the guide member. Even if it is performed, the formation of the gap between the air conditioning member and the apron is suppressed, and the generation of wind noise can be suppressed.
[0022]
