Abstract

PURPOSE:To release the check of the opening of lid by an electromagnetic lock device, by providing the electromagnetic lock device to check the opening of the lid at the lower side of an operator control panel, and operating either preset button for a specific floor, of an opening button, a closing button, and a destination floor regestered button. CONSTITUTION:When a maintenance worker wants to convert to the maintenance mode in an inspection,he rides in a cage, and inserts and turns the key in the key hole for the elevator operation panel, to release the fitting piece 11 of the fitting body 10 of a lid 6. And, while he is pushing an operating button 33, an electromagnetic coil 8 is excited, an operating piece 7 is operated to the right side, and the lid 6 can be opened. And, while he is pushing a closing button 32, the electromagnetic coil 8 is excited to operate the operating piece 7 to the right side, and the lid can be opened. Furthermore, while he is pushing a destination call registered button 43 for the uppermost floor or the lowermost floor, the electromagnetic coil 8 is excited to operate the operating piece 7 to the right side, and the lid can be opened. Therefore, a person who knows no operating method cannot operate verious operation switches provided in the operator control panel.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement of a locking device in an elevator operation panel.

[Conventional technology]

The elevator operation panel is, for example, Utility Model No. 582026.
The structure is as shown in Publication No. 0, and if a user who is not familiar with elevators accidentally operates the various operation switches installed in this operation panel, the elevator may stop suddenly or , it may stop at an intermediate position between floors.

In such a case, passengers may become trapped in the car, or the elevator may become inoperable. For this reason, the elevator is closed with a lid so that general users cannot operate it, and is locked using a specific key carried by elevator maintenance personnel.

[Problem to be solved by the invention]

By the way, this key is also managed by the customer.
An unspecified person poses as a maintenance worker from the elevator company, borrows the key from the customer, operates a series of various operation switches, and makes the elevator inoperable.The customer entrusts maintenance work to the customer. For the maintenance company that is
In addition, a problem that is extremely inconvenient for customers has also arisen.

Therefore, the present invention has been made in view of the above-mentioned circumstances, and its object is to provide an elevator operation panel in which the lid of the operation panel cannot be opened using only the above-mentioned key.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a destination floor registration button provided in the car to register the destination floor of the car, and a destination floor registration button for preventing the door closing operation and reversing the closing door. An elevator that has a door opening button, a closing button that facilitates the door closing operation, and a communication device for external calls, and that the lower part is normally closed with a lid and is in a locked state, and that has various operation switches inside. The operation panel is equipped with an electromagnetic locking device that prevents the lid from opening.
The vehicle is characterized by being provided with a release means that releases the electromagnetic locking device from blocking the opening operation of the cover when one of the close button and the destination floor registration button is operated for a predetermined specific floor. .

[Effect]

Since the present invention has the above-mentioned configuration, it is impossible to open the lid of the driver's panel without knowing a specific operating method, so that an unspecified person can operate the various operation switches provided in the driver's panel. It is possible to reliably prevent manipulation.

〔Example〕

Hereinafter, embodiments of the elevator operation panel of the present invention will be described based on the drawings.

FIG. 1 is a longitudinal sectional view showing an embodiment of an elevator operation panel of the present invention, and FIG. 2 is a circuit diagram for operating an electromagnetic device.

In Fig. 1, 1 is an intercom 2 for communication with the outside, and when operated, it listens to the closing operation of the door.
A door opening/closing control button 3, which is an opening button for reversing a door that is closing, and a closing button for promoting the door closing operation, a destination floor registration button 4 for registering a car destination floor, and an elevator button. This driving operation panel is equipped with various operation switches 9 for changing the operation mode by operating the operation mode.
A lid 6 is provided to close the part to which the lock is attached, and when a key (not shown) is inserted into the keyhole 5 and operated, the engaging body 1-○ is engaged by a locking piece 11 that interlocks with the locking piece 11. It is provided.

Further, the operation panel 1 is provided with an electromagnetic device 8 having an actuating piece 7 that prevents the lid 6 from opening unless it is energized even when the engaging body 10 is disengaged from the locking piece 11. ing.

FIG. 2 is an operating circuit diagram of the electromagnetic device 8 that allows the electromagnetic device 8 to open the lid 6.
□ is the normally open contact of the open chain among the above-mentioned buttons 3, 3□ is the normally open contact of the closed button among the buttons 3, and 4□ is the destination of the second or lowest floor of the above-mentioned destination floor registration buttons 4. A normally open contact of the floor registration button, 20 is provided in the electromagnetic device 8, and the operating piece 7 is connected to the lid 6.
The electromagnetic coil is operated in the direction in which it opens, that is, in the right direction in this figure, (+) and (-) are the control power supply, and the normally open contacts 3□, 32, and 41 are connected in parallel. An electromagnetic coil 20 is directly connected to this circuit, and is connected between control power supplies (+) and (-).

Next, the operation of this embodiment in the following configuration will be explained.

When an elevator maintenance worker wants to switch to maintenance mode during inspection, he gets into the car, inserts the elevator operating panel key into the keyhole, and operates the locking piece of the engaging body 10 of the lid 6]-
1 is canceled. While pressing the open chain 3□ on the door, the electromagnetic coil 8 is energized, the operating piece 7 moves to the right, and the lid 6 can be opened. Further, while the close button 32 is pressed, the electromagnetic coil 8 is energized, the operating piece 7 is operated in the right direction, and the lid 6 can be opened. Furthermore, while pressing the ``most'' second floor and lowest floor destination call registration buttons 4□, the electromagnetic coil 8 is energized.
The operating piece 7 operates in the right direction, allowing the lid 6 to be opened.

According to this embodiment, unless one knows a specific operation method for opening the lid 6, the lid 6 cannot be opened simply by having a key for unlocking the operation panel. A person who does not know how to operate the elevator is prevented from operating the various operation switches 9 provided on the operation panel, and therefore, for example, mischief such as intentionally disabling the elevator can be reliably prevented.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to reliably prevent various operation switches provided in the driving operation panel from being operated in an unspecified manner.
