Abstract

PURPOSE:To protect an elevator from a submerged accident at the time of flood damage by providing a refuge story pause switch for stopping a car to the uppermost story and in the vicinity of the uppermost story, in an operating device provided with a stop switch for switching the elevator to operating and stopping conditions. CONSTITUTION:A refuge story stop switch KS is provided in the vicinity of a door D of an elevator in an arbitrary story, for instance, the first floor of a building. This switch KS is provided for placing a car in a stop condition to take refuge in the uppermost story or a story in the vicinity of the uppermost story of the elevator stop stories, and by inserting a key into a key guide 11 rotated to a position 'refuge', the car is stopped to take refuge in a refuge story. That is, when the refuge story stop switch KS is not operated, an actuator S is connected to a teminal 1a to energize an operation command relay A, turn on a normally-opened contact Aa and to form a normal operation circuit E, and when the switch KS is operated, the relay A is deenergized to turn on a normally-closed contact Ab and to form a refuge stop circuit F.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator operating device, and more particularly to an elevator operating device that protects an elevator from a flood accident in the event of water damage.

[0002]

2. Description of the Related Art Conventionally, in order to protect an elevator from flood damage caused by heavy rain such as typhoon, which falls in the elevator hoistway and floods the equipment on the elevator car, the elevator car Was operated to the top floor in the hoistway, and the car was stopped at the top floor by operating the stop switch provided in the operation panel in the car. Further, as described in Japanese Utility Model Laid-Open No. 3-18071, there has been proposed a parking switch provided on each floor so that a car can be rested on an arbitrary floor to select a rest position during normal operation and during flood damage.

[0003]

In the former case of the above-mentioned prior art, since the elevator door is stopped while the door is open, rainwater may infiltrate into the car and the hoistway. In the latter case, there was a physical pain in that the car had to be operated down the stairs after operating the parking switch on the upper floor to pause the car on that floor.

It is an object of the present invention to provide an elevator operating device which can easily and surely stop at an evacuation floor that protects an elevator from water damage.

[0005]

In order to achieve the above object, the present invention is an elevator operating apparatus having a stop switch for switching an elevator between an operating state and a stopped state. There is an evacuation floor pause switch that pauses near the floor.

[0006]

As described above, according to the present invention, the evacuation floor stop switch for stopping the car on the top floor and the vicinity of the top floor is provided as described above. Operate the floor sleep switch. Therefore, when the evacuation floor is stopped, the operation of the administrator can be facilitated, and at the time of flood damage, it is possible to prevent the flood damage on the elevator car equipment.

[0007]

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, an evacuation floor stop switch KS provided in the vicinity of an elevator door D on an arbitrary floor of the building, for example, a first floor having an entrance / exit of the building, is an evacuation floor suspension switch KS on the top floor or near the top floor among elevator stop floors In this embodiment, the switch is a switch for evacuating the car to the 5th floor, which is the top floor, and put it in a dormant state. An evacuation display (not shown) is provided on it, and a car (not shown) can be evacuated to the fifth floor by inserting and rotating a key (not shown) in the key guide 4.

The fixed terminal C of the operator S of the evacuation floor suspension switch KS is connected to the control power supply P, and an elevator is installed between the terminal 1a and the control power supply N which are in contact with the operator S when the evacuation suspension switch S is not operated. An operation command relay A having a normally open contact Aa and a normally closed contact Ab that are normally operated is connected.

A normally open contact Aa and an operation circuit E for performing normal operation of the elevator are connected in series between the control power supplies P and N. Similarly, an evacuation suspension circuit F for evacuating the normally closed contact Ab and the car to the fifth floor to put the elevator in a suspension state is connected in series between the control power supplies P and N.

Next, the operation will be described. When the evacuation stop switch KS installed on the first floor is not operated, the operator S comes into contact with the terminal 1a to form a circuit P-C-S-1a-A-N to activate the operation command relay A. As a result, a P-Aa-E-N circuit is formed and the elevator operates normally.

On the other hand, when the car may be flooded due to a typhoon or the like, when the administrator operates the evacuation stop switch KS, the operator S comes into contact with the terminal 2a, and P-C-S-
The circuits 1a-A-N are opened and the operation command relay A is deactivated. At the same time, the P-Aa-E-N circuit is opened, and P
Since the circuit of -Ab-F-N is formed, the car goes straight to the 5th floor, which is the evacuation floor, and the elevator is in a dormant state with the door closed.

In the present embodiment, the evacuation stop switch KS
However, the evacuation stop switch KS may be provided in any place, for example, the building management room. Further, in an elevator where parking operation is carried out, the parking operation switch may be incorporated with an evacuation floor suspension switch as shown in FIG. 3 so that the parking operation switch and the evacuation floor suspension switch can be switched by a key operation. Has the effect of.

[0014]

According to the present invention, by providing the evacuation floor suspension switch for suspending the car to the top floor and the vicinity of the top floor, the manager decides whether or not to suspend the elevator depending on the amount of rainfall and evacuates. Operate the floor sleep switch. Therefore, when the evacuation floor is stopped, the operation of the administrator can be facilitated, and at the time of flood damage, it is possible to prevent the flood damage on the elevator car equipment.
