JPH06298469A - Control circuit of elevator operation panel - Google Patents

Abstract

PURPOSE:To prevent a floor of destination from being registered unless an engine is stopped by providing the control circuit of an operation panel with a key switch for turning on and off the power supply to the circuit, and enabling the key switch to be turned on and off by means of the engine key of any automobile that uses an elevator car. CONSTITUTION:Even if a destination floor registering switch inside an operation panel 3 is operated after an automobile 2 gets into an elevator car 1, the floor of destination cannot be registered since a key switch 8 for turning on and off the circuit power supply to a control circuit 5 is not operating. However, since the key switch 8 for turning on and off the circuit power supply to the control circuit 5 is operable by insertion of the engine key 6 of the automobile 2 into a key hole provided in the operation panel 3, the floor of destination can be registered by control of the destination floor registering switch. After the elevator has landed on the floor desired, the engine key 6 is removed from the key hole 7 so that the circuit power supply to the control circuit 5 is interrupted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operating circuit for an elevator driver's panel, and more particularly to an operating circuit for an elevator driver's panel which is suitable for preventing runaway of a car in a car.

[0002]

2. Description of the Related Art The operation panel in the car of an automobile elevator is
In consideration of the convenience of the vehicle driver's panel, it is common to reach out from the driver's seat of the vehicle to operate the destination floor registration button. 50-81572, Japanese Utility Model Laid-Open No. 63-16
7443 publication etc. are mentioned.

[0003]

By the way, recent automobiles are increasing in number of automatic vehicles, and even if a driver of an automatic vehicle operates the destination opening button without stopping the engine even when he / she gets in the car, his / her feet are separated from the brake pedal. Accidents such as suddenly moving forward or suddenly increasing the number of revolutions of the engine and erroneously starting to hit the walls or doors of the hoistway have occurred.

The object of the present invention is to solve the above problems.
It is to provide an operation circuit for an elevator operation panel that cannot register the destination floor unless the engine is stopped.

[0005]

In order to achieve the above-mentioned object, the present invention provides an operation circuit of an elevator operation panel equipped with a destination floor registration switch, wherein a circuit power supply opening / closing key switch is provided in the operation circuit of the operation panel. At the same time, this key switch can be turned on and off by the engine key of any car using a car.

[0006]

According to the present invention, the destination floor cannot be registered unless the engine key is removed and the engine key is inserted into the driver's panel, so there is an effect of preventing a runaway accident in the car.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a plan view of a car for an automobile elevator, FIG. 2 is a front view of an in-car driving panel, FIG. 3 is a side view of a main portion of FIG. 2, and FIG.

1 is a car for an elevator, 2 is a car in the car 1, 3 is a driver's panel mounted in the car 1, 4 is a destination floor registration switch incorporated in the driver's panel 3, 5 is a destination An operation circuit in which the circuit is closed by operating the floor registration switch 4, 6 is an engine key of the automobile 2 in the car 1, 7 is a key hole for inserting the engine key 6 provided on the driver's panel 3, and 8 is an engine key 6 is a key switch for opening and closing the circuit power of the operation circuit 5 which operates by inserting 6 into the keyhole 7.

The operation of one embodiment of the present invention having such a structure will be described below. Even if the car 2 is placed in the car 1 of the elevator and the destination floor registration switch 4 in the operator panel 3 is operated, the key switch 8 for opening and closing the circuit power supply of the operation circuit 5
Is not working, so the destination circuit cannot be registered. However, by inserting the engine key 6 of the automobile 2 into the key hole provided in the driver's panel 3, the circuit power source opening / closing key switch 8 of the operation circuit 5 operates, so that the destination floor registration switch 4
You can register the destination floor by operating. After the elevator has landed on the destination floor, the engine key 6 is pulled out from the key hole 7, so that the circuit power of the operation circuit 5 is cut off.

[0011]

According to the present invention, the destination floor cannot be registered unless the engine key is removed and the engine key is inserted into the driver's panel. Therefore, there is an effect of preventing a runaway accident in the car.
