Description

[Detailed Description of the Invention] The present invention relates to an emergency rescue device for transferring passengers from an elevator to an adjacent elevator when an elevator makes an emergency stop on a non-stop floor. This relates to a side emergency rescue device installed in a.

In buildings such as high-rise buildings that have hoistways with relatively long elevator travel, high-floor service elevators often have lower floors that do not stop in order to increase the speed and operate the elevators with high efficiency. In the unlikely event that such an elevator makes an emergency stop on a floor where it cannot stop, the method of rescuing passengers from the car is to stop the elevator adjacent to the elevator that made an emergency stop at the same level, and to remove the opposite car side panels of both elevators. A method is used in which the emergency rescue doors provided at the car are opened and passengers from the car that has made an emergency stop are transferred to the adjacent car.

A conventional side emergency rescue device for an elevator will be explained below with reference to the drawings. Fig. 1 is a front view showing two adjacent elevator cars, and Fig. 2 is a front view of two adjacent elevator cars.
It is an A sectional view. In the figure, 1 is a car, 2 is a handrail that forms a link mechanism, and 3 is a treadle. Normally, the handrail 2 and treadle 3 are folded toward the car 1 side so that they do not interfere with elevator operation. There is.

During emergency rescue work, the emergency rescue door 4, which forms part of the side panel of the car, is opened as shown by the two-dot chain line in Figure 2, and the handrail 2 and treadle 3 are pulled out to remove the passengers who have come to an emergency stop. is transferred to an adjacent car.

However, as shown in FIG. 3, in the case of a car in which handrails 10a to 10d are provided, the handrail 10b is connected to the handrail 10 even when an attempt is made to open the emergency rescue door 4.
c, the emergency rescue door 4 cannot be opened fully.
The drawback was that it interfered with passenger rescue operations.

The purpose of this invention is to overcome the above-mentioned drawbacks of the conventional methods. Even in the case of cars equipped with handrails, the emergency rescue door can be opened sufficiently to prevent passenger rescue operations from being hindered. It was designed so that

An embodiment of the present invention will be described below with reference to the drawings.
Figure 4 is a cross-sectional view of the basket, and Figure 5 is B- in Figure 4.
This is a cross-sectional view of B, and the handrail 10b is rotatable around a shaft portion 11, and the shaft portion 11 is provided in the emergency rescue door 4 so that it can move forward and backward. The details will be explained below.

Figure 6 is a detailed view of part C in Figure 5, and shows the handrail 10.
FIG. 7 is a cross-sectional view taken along line DD in FIG. In the figure, 20 is the handrail 10
The engagement plate 21 provided at one end of b is a receiver for the engagement plate 20 fixed to a board 22, and the board 22 is fixed to the emergency rescue door 4.

FIG. 8 is a sectional view taken along line E-E in FIG.
1 is a detailed explanatory diagram of FIG. In the figure, 30 is a spacer fixed to the emergency rescue door 4, 31 is an auxiliary member whose flange part is bolted to the spacer 30, and a male thread 31a is cut in the part that protrudes into the car. It has a hollow part that communicates between the inside and outside. Reference numeral 32 designates a support member implanted in the handrail 10b, and has a female thread 32a cut inside. 33 is a shaft, which has a male thread 33a cut at one end and the female thread 3 mentioned above.
2a to be integrated with the support member 32, and the other end is inserted into the hollow part of the auxiliary member 31, and a stopper 34 is bolted to the tip. 35 is the lock nut, and the shaft 33
The support member 32 is screwed onto the support member 32 in advance.
A female thread 35a is cut on the inside thereof.

In a normal state, as shown in FIG. 6, the engagement plate 20 is housed in the receiver 21, and the female thread 35a of the lock nut 35 and the male thread 31a of the auxiliary member 31 are screwed together, so that the handrail can be removed easily. 10b is fixed.

When opening the emergency rescue door 4 to rescue passengers in the car, the lock nut 35 is first loosened and removed from the auxiliary member 31. Next, as shown in FIG. 5, rotate the handrail 10b in the
Pull b towards the inside of the car (Z direction in Figure 8) and rotate it in the Y direction in Figure 5.

When the emergency rescue door 4 is opened, the handrail 10b and the handrail 10c do not interfere with each other as shown in FIG. 4, so the emergency rescue door 4 can be opened sufficiently and the emergency rescue work can be carried out without any hindrance.

As described above, according to this embodiment, even if the car is equipped with a handrail, the emergency rescue door 4 can be opened sufficiently, so that the rescue work for the passengers inside the car can be carried out quickly.

FIG. 9 shows another embodiment of the present invention, and is a diagram corresponding to FIG. 7. In the figure, 40 is the bolt installed in the emergency rescue door 4, and 41 is the handrail 1.
This is an insertion hole for a bolt 40 provided at the end of 0b. Normally, the handrail 10b is held by inserting the bolt 40 into the insertion hole 41, and when the emergency rescue door 4 is opened, the state shown in FIG. The handrail 10b is removed from the bolt 40 as shown in FIG. In addition, the insertion hole 4
1 has a bent part 41a inside, but the handrail 1
If the wall thickness of 0b is thick, the bent portion 41a may be omitted. FIG. 10 shows still another embodiment, in which a bolt 43 is screwed into a nut 42 fixed to the emergency rescue door 4, and a drill hole 44 is provided at the end of the handrail 10b. Since the head of the handrail 10b is inserted into the large diameter portion 44a of the daruma hole 44 and held at the small diameter portion 44b, the holding of the handrail 10b is more stable than in the embodiment shown in FIG.
According to the embodiment shown in FIGS. 9 and 10, the handrail 10
This has the advantage that the design effect is excellent because the device that holds b is not visible from inside the car.

As explained above, according to the present invention, even in the case of a car equipped with a handrail, the emergency rescue door can be opened as far as possible in the case of a car without a handrail.
This has the effect that rescue work for passengers in the car can be carried out quickly and safely.
