DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rescue device for a double deck elevator.

[0002]

2. Description of the Related Art In recent years, various techniques have been considered for planning an elevator to be installed in accordance with an increase in the height of a building. However, as buildings become increasingly high-rise and large, elevator plans have not been developed with very effective measures and methods, and elevator services are often in short supply. For this reason, a double-deck elevator in which two cars are connected to each other on the hoistway of one elevator may be used.

A configuration of a conventional double deck elevator will be described with reference to FIG.

[0004] The double deck elevator is connected by a car frame 3 in which an upper car 1 and a lower car 2 surround the car. The car frame 3 includes an upper frame 5 connecting a main rope 4 for suspending the car above the upper car 1, a lower frame 6 for the upper car receiving the upper car 1, and a lower car receiving the lower car 2. A lower frame 7 is provided.

Further, ceiling rescue exits 8 and 9 are provided on the ceilings of the upper car 1 and the lower car 2, respectively.

[0006]

In a double-deck elevator, the distance between the upper car and the lower car is limited by the height of each floor and the height of each car. Although a rescue device can be provided with a rescue exit on the ceiling of the car, even if a rescue device is provided on the ceiling of the lower car, the gap between the upper and lower cars is narrow, and maintenance personnel enter between the cars. In many cases, it is difficult to rescue passengers, and it is often impossible to provide a rescue device on the ceiling of the lower car.

In view of the above, the present invention provides a rescue device capable of transferring a passenger in a lower car of a double-deck elevator to an upper car, and rescues a passenger in case of a failure without being locked in the car for a long time. With the goal.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a double deck elevator with a ceiling rescue exit at the upper car ceiling, and a side rescue exit on each side of the upper car and the lower car. Attach a moving ladder between the upper car side rescue exit and the lower car side rescue exit. An emergency ramp is attached to the side of the lower car on the side of the rescue exit, and a safety fence is attached to the emergency ramp to prevent falling.

[0009]

In the rescue apparatus having the above configuration, when the double-deck elevator breaks down and stops between floors, the elevator maintenance staff sends the passengers in the upper car from the ceiling rescue exit of the upper car to the passengers in the upper car. To rescue.

[0010] For the lower car, the elevator maintenance staff descends from the side rescue exit of the upper car to the emergency ramp using the moving ladder, and then the elevator maintenance personnel opens the lower car side rescue ramp with the emergency ramp to lower the car. Rescue the passengers in the car and guide them to the upper car.

The emergency ramp is placed on the side of the lower car while the elevator is running, so that it does not hinder the elevator traveling. The safety fence attached to the emergency ramp is used to prevent secondary disaster during rescue. It is for prevention.

[0012] Even if the double-deck type elevator stops in the middle of each floor due to a failure or the like as described above,
Since the passengers in the upper and lower cars can be rescued by the elevator maintenance staff, the situation in which the passengers in each car are locked in the cars for a long time does not occur.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the embodiments shown in FIGS.

The double deck elevator has an upper car 1,
The lower car 2 is composed of a car frame 3 for connecting and supporting two cars. The car frame 3 is composed of an upper frame 5 for connecting the main rope 4, a lower lower frame 6 for receiving the upper car 1, and a lower lower frame 7 for receiving the lower car 2 in addition to the vertical frame 3a. 1 and 2 are supported by the vertical frame 3a, the upper frame 5, and the lower frames 6 and 7.

In the rescue apparatus, a ceiling rescue exit 8 is provided on the ceiling of the upper car 1, and an upper car side rescue exit 10 and a lower car side rescue exit 11 are provided on the sides of the upper and lower cars 1, 2, respectively. Lower car side rescue exit 1 than upper car side rescue exit 10
1, a moving ladder 12 is attached, and a lower car side exit 11
An emergency ramp 13 is provided outside, and the elevator is turned upside down on the side of the car during operation of the elevator so as not to hinder the operation. The emergency ramp 12 is provided with a safety fence 14 for preventing falling.

The control circuit of the present invention will be described with reference to FIG.

Hall call button 1 provided at the elevator hall
By registering at 5, the signal is the hall call signal line 1
6a to y are transmitted to the input register 18 of the small computer 17. A signal is transmitted from an output register 19 of the small computer 17 to an elevator operation control circuit 21 through an elevator control circuit output signal line 20 ao. Further, the signal is transmitted to the elevator driving control circuit 23 through the elevator driving circuit output signal lines 22a to 22p, and the elevator goes to the floor where the hall is called.

The elevator arrives at the floor with the hall call,
The user enters the car, the user of the upper car 1 registers the destination floor by the upper car call button 24, and the user of the lower car 2 registers the destination floor by the lower car call button 25, and the signal is the upper car call signal line 26a. ~ M or lower car call signal line 27a ~
n is input to the input register 18 of the small computer 17 and the elevator travels to the registered destination floor.

If the elevator is out of order, the elevator operation control circuit 21 sends an operation abnormality signal to the small computer 17 via an elevator operation abnormality output signal line 28a-r.
Is input to the input register 18. Furthermore, a small computer 17
From the output register 19 of the elevator failure circuit output signal line 29a-q to the elevator failure arrival control circuit 30
The elevator attempts to continue operation to the nearest floor, but depending on the degree of breakdown, if the elevator stops between floors, rescue by elevator maintenance personnel is required.

When the double-deck elevator stops in the middle of each floor due to a failure or the like, the passengers in the upper car 1 are rescued from the ceiling rescue exit 8 by elevator maintenance personnel. Lower basket 2
For passengers inside the elevator, the elevator maintenance staff uses the emergency ladder 13 with the moving ladder 12 from the upper car side rescue exit 10.
To the lower car, open the lower car side rescue exit, and take passengers to the upper car 1
Guide and rescue.

As another embodiment of the present invention, a rescue exit is also provided on the ceiling of the lower car 2 and an emergency rescue exit is also provided on the floor of the upper car 1 so that the lower car 2 can be moved from one floor of the upper car 1 to the lower car 2. A passenger may be rescued by providing a movable staircase or a ladder on the ceiling.

In addition, the emergency ramp 13 is registered with a lower car call, and can be automatically set in a state where it can be got on and off when it stops between floors due to a failure.

[0023]

According to the present invention, when a double deck elevator stops between floors due to a failure or the like, it is possible to safely rescue the passengers in the lower car and to keep the passengers for a long time. And a safe and reliable elevator can be provided.
