JPH0597338A - Escape device for elevator - Google Patents

Abstract

PURPOSE:To permit the escape by a passenger himself by shifting a cage to a floor level by driving out the extension part of a wire rope which is previously installed, from a taking-up device, when an elevator stops between floors. CONSTITUTION:When an escape device door 15 is opened, a door switch 16 operates to separate an elevator control panel front an electric power source. Then, a brake pedal 14 is stepped ON to loose a brake 12, and a taking-up handle 8 is turned to revolve a wire taking-up device 4, and a wire rope 6 which is previously wound is driven out. Since a cage 5 lowers by the driven-out length of the wire rope 6, a cage position display mark 17 is confirmed from a cage position confirming window 18, and the handle 8 is turned, and then the cage 5 is lowered to a floor level, and the escape by a passenger himself is enabled.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an escape device when an elevator car is stopped between floors due to a failure or the like.

[0002]

2. Description of the Related Art Conventionally, when an elevator car is stopped on an intermediate floor due to a power outage, a breakdown, etc., passengers trapped in the car ask the manager to rescue the car by using an emergency button or an intercom. Contacted the elevator service company, and the elevator serviceman, who was driven by the contact, moved the car to the landing level or rescued passengers from the rescue exit.

[0003]

Therefore, when the elevator is stopped during operation, the manager is absent, or the elevator service company is in a remote area, it takes time to start the rescue operation. , Passengers will be forced to can for a long time in the car. In particular, this is inconvenient, even though the patient needs to be urgently rescued when he / she is in a hospital bed elevator.

It is an object of the present invention to provide a device capable of preventing passengers from being trapped in a car for a long time when the elevator is stopped between floors and allowing the passenger to escape by himself / herself.

[0005]

[Means for Solving the Problems] A wire rope winding device is provided on a car, and the tip of the wire rope for hanging a car having a length equal to or longer than the maximum floor distance is wound around the device. The take-up handle of the escape device take-up device is installed in the car,
This is connected by a chain or the like, and further, a brake for this winding device is provided, and this brake release handle is also provided in the car.

Separately, a mark is attached to the hoistway so that the car position can be confirmed from the car confirmation window when the car is moved.

The above-mentioned winding handle, brake release handle, car position confirmation window, etc. provided in the car are provided at one corner of the car, and are separated by the escape device door. Further, in conjunction with this door, the elevator control panel Provide a door switch to disconnect the power and stop its operation.

Thus, the emergency car escape device is constructed.

[0009]

With such an escape device, when the car stops between the floors, the passenger opens the escape door and operates the door switch to disconnect the elevator control panel from the power source, thereby ensuring electrical safety. Then, turn the brake release handle of the winding device to release the brake, rotate the winding handle to release the wire rope, and lower the car while checking the car position from the confirmation window provided on the side wall of the car. , Land on the lower floor and escape from the car.

[0010]

The present invention will be described based on the embodiment shown in FIG.

A wire rope winding device 4 including a worm gear 1, a worm wheel 2 and a winding drum 3 is installed on a car, and a tip of a wire rope 6 suspending a car 5 is fixed to the car. Then, the building is extended by the length corresponding to the longest floor height of the building, and the tip end portion is wound around the winding drum 3.

A worm gear 1 meshing with a worm wheel 2
A chain wheel 7 is provided on the shaft of the above, and a chain 10 is wound around the chain wheel 9 at the tip of a manual winding handle 8 provided in the car 5 to form the drive means of the winding device 4.

Further, a brake drum 11 is provided in the middle of the worm gear shaft, a brake device 12 for tightening the brake drum 11 by spring force is provided, and a link 13 is arranged from the brake device 12 to the floor of the car. Install 14.

A corner of the car is partitioned by an escape device door 15 provided at one corner of the car, and the winding handle 8, the brake pedal 14, etc. are accommodated therein.

A door switch 16 for electrically connecting to the elevator control panel is attached to the back side of the escape device door 15 so that the elevator control panel can be disconnected from the power supply.

Further, a car position display mark 17 is provided on the wall surface of the hoistway.
The car position confirmation window 18 is provided in the partition.

The escape device from the car is constructed as described above.

When the car 5 is stopped between the floors and the escape device is used, first, the escape device door 15 is opened to operate the door switch 16 to disconnect the elevator control panel from its power source and to electrically disconnect the elevator. Ensure safety.

Depress the brake pedal 14 to brake 12.
Is loosened, the winding handle 8 is rotated, the wire rope winding device 4 is rotated, and the wire rope 6 which has been wound in advance is fed out.

Since the car 5 is lowered by the length of the operated wire rope 6, the car position confirmation window 18 is used to check the car position display mark 17 of the hoistway, and the handle 8 is rotated.
It is possible to lower the car 5 to the landing level and escape by itself.

As another embodiment of the present invention, by increasing the gear ratio of the worm wheel 2 and the worm gear 1, the car 5 can be raised and landed.

Further, instead of the manual operation of the winding handle 8,
A battery may be provided in the car 5 and the winding handle 8 may be rotated by a motor.

Similarly, the brake device 12 is operated by the battery provided in the car 1 to operate the brake pedal 1 of the foot.
Instead of 4, the brake can be released by operating an electric switch.

[0024]

According to the present invention, when the elevator is stopped between floors, the extension part of the wire rope wound in advance is operated by the winding device and the car is moved to the landing level. It enables escape and prevents passengers from being trapped in the car for a long time.
