Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an elevator apparatus, and more particularly to an elevator apparatus provided with a fire shutter device at a landing entrance / exit between a hoistway and a floor.
[0002]
[Prior art]
Conventionally, for example, Japanese Patent Application Laid-Open Nos. 2001-276243 and 2001-276244 have been proposed as elevator devices including a fire shutter device at a landing entrance / exit between a hoistway and a floor.
[0003]
[Problems to be solved by the invention]
Usually, an elevator is provided with an indicator in the vicinity of a landing door as shown in Japanese Patent No. 2521576. However, when a fire shutter device as shown in the above prior art is provided at a landing entrance, the fire shutter and Had to put an indicator at an unrelated position.
[0004]
For this reason, the position where the indicator is provided has to be provided with a hole in a part of the building wall away from the fire shutter device, which requires a lot of labor and cost. There is also a problem that it is difficult to see the passengers because it is located away from the landing door.
[0005]
The objective of this invention is providing the elevator apparatus provided with the indicator which has little labor and cost, and is easy to see.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a hoistway for raising and lowering a car, a landing entrance entrance provided on a hoistway partition building wall so as to communicate the hoistway and the floor of the building, and the landing and the landing door apparatus comprising a landing door and jamb to open and close the and out frontage part, the fire shutter device provided with a fire shutter for closing the fire at the hall and out frontage part provided on floor side of the hall door apparatus In the hall entrance / exit opening provided, an up / down guide mechanism for guiding both sides of the fire shutter in the width direction is provided independently of the three-way frame at the entrance / exit entrance and covers both sides of the up / down guide mechanism. A decorative cover is provided, and an indicator is provided on the decorative cover .
[0007]
According to the above arrangement, the cover for covering both sides of the fire protection shutter of the fire shutter device, since the indicator is provided, it is not necessary holes in the wall, therefore, becomes cheaper only if costs not applied effort, Moreover, it can be provided in the vicinity of the landing door, and is easy for the user to see.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
[0009]
FIG. 1 is a cross-sectional plan view showing an embodiment of a hallway entrance / exit of an elevator apparatus according to the present invention, FIG. 2 is a front view seen from the floor side of FIG. 1, and FIG. FIG. 4 is a side view and FIG. 4 is a plan view of a shutter portion showing another embodiment of the present invention.
[0010]
A hoistway 2 in which a car 1 ascends and descends is vertically formed in a section of the building, and a hallway entrance 4 is provided on a building wall W that partitions the hoistway 2 and each floor 3. And each floor 3 are configured to communicate with each other.
[0011]
A landing door device that opens and closes the hoistway 2 is provided near the hoistway 2 at the landing entrance 4. This landing door device includes a three-sided frame 5 including a pair of vertical frames 6A and 6B on both sides of the frontage that divides three sides of the entrance / exit entrance 4 and an upper frame 7 connected to the upper ends of the vertical frames 6A and 6B. The landing doors 8A and 8B open and close the hoistway side of the three-way frame 5. The landing doors 8A and 8B are installed at positions facing the car doors 9A and 9B of the car 1 when the car 1 reaches the floor 3, and the car door is driven by a door engaging device (not shown). 9A and 9B are engaged to open and close in synchronization.
[0012]
On the other hand, a fire shutter device 10 is provided near the floor 3 side of the hall entrance / exit opening 4 and detects the fire in the event of a fire, or automatically or by a command from the fire prevention center. 4 is configured to be closed.
[0013]
The fire shutter device 10 is positioned at the upper part of the entrance / exit entrance 4 and the fire shutter 11 that moves in the vertical direction, the vertical guide mechanisms 12A and 12B that guide both sides of the fire shutter 11 in the width direction, and the fire shutter. 11 and a speed reduction mechanism 14 of the winding mechanism 13. The upper and lower guide mechanisms 12A and 12B are attached to the entrance / exit entrance, for example, with a gap material (not shown) interposed so as to eliminate the gap with the entrance / exit entrance 4 and the winding mechanism. 13 is pivotally supported by a support member fixed to the upper ends of the vertical guide mechanisms 12A and 12B or a support member fixed to the entrance / exit opening.
[0014]
In addition, a decorative cover is formed on the floor 3 side of the entrance entrance 4 so that the vertical guide mechanisms 12A, 12B and the winding mechanism 13 of the fire shutter 11 cannot be seen from the floor 3 side. Yes. This decorative cover covers the pair of decorative covers 15A and 15B covering the vertical guide mechanisms 12A and 12B and the winding mechanism 13 of the fire shutter device 10 across the upper ends of the decorative covers 15A and 15B on the floor side. The decorative cover 16 and the building cover W are attached to the building cover W, respectively. Among the decorative covers 15A and 15B, the decorative case 15A is provided with an indicator 17 having call buttons for raising and lowering. In addition, the decorative cover 16 is provided with an indicator 18 indicating the operation direction and position of the car 1.
[0015]
Thus, since the indicators 17 and 18 are provided on the decorative covers 15A and 16, it is not necessary to provide a hole in the building wall W.
[0016]
In this embodiment, the example in which the indicator 17 is provided on the decorative cover 15A has been shown. However, as shown in FIG. 4, the vertical guide mechanisms 20A and 20B are configured to be wide, and the vertical guide mechanisms 20A and 20B. In this case, it may be provided at 20A.
[0017]
Moreover, although the example which provided the indicators 17 and 18 in both makeup | decoration covers 15A and 16 was shown, the indicator 18 may be aggregated and provided only in the makeup | decoration cover 15A, or even if it provides in the makeup | decoration cover 15B side. Good. In addition, in the case of a customer who requests simplicity of the hall, the indicator 18 is omitted and an arrival forecasting device (chimes and guidance by voice) is provided, but in this case, it may be provided in any of the decorative covers 15A and 18.
[0018]
As described above, since the indicator is provided on at least one of the decorative covers 15A, 15B, and 16 covering the upper surface or both sides of the fire shutter, it is not necessary to make a hole in the wall, and therefore, labor is not required. Costs are also reduced, and it can be provided near the landing doors 8A and 8B, making it easy for the user to see.
[0019]
【The invention's effect】
As described above, according to the present invention, since the indicator is provided on at least one of the decorative covers that cover the upper surface or both sides of the fire shutter, it is not necessary to make a hole in the wall, and therefore, labor is not required. Costs are also reduced, and it can be installed near the landing door, making it easy for the user to see.
