Abstract

PROBLEM TO BE SOLVED: To mitigate the fretfulness of a waiting passenger at a landing by providing a flicker lighting circuit during the door opening extension of a floor indicator lamp of an indicator provided on each landing of a plurality of floors. SOLUTION: If a door opening extension button provided in a car is pushed when a door of an elevator is opened, a constantly open contact ROPa is closed by the door opening extension command to form a P-ROPa-FOP-N circuit, and a flicker device FOP is operated. The constantly closed contact FOPb of the flicker FOP is flicked to intermittently form a P-FOPb-LFL-N circuit, and a floor indicator lamp LFL is flicked to inform a waiting customer at a landing of the door opening extension condition. When the opening extension is completed, the constantly opened contact ROPa is opened when the door closing command is generated, the flicker FOP completes the action. The constantly closed contact FOPb of the flicker FOP is closed to constantly form the P-FOPb-LFL-N circuit, and the floor indication lamp LFL is returned to the normally lit condition.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator display circuit.

[0002]

2. Description of the Related Art Generally, there is no display device on the landing side of an elevator to indicate that the elevator is in a door-open extension state, so that the state cannot be known on other floors.

[0003]

In the prior art, since the waiting state of the elevator is not known to the waiting customers on the other floors, the longer the stopping state of the elevator, the more frustrated the waiting guests are. Was.

An object of the present invention is to provide an elevator display circuit capable of reducing a feeling of frustration for a waiting passenger at a landing.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an elevator having an indicator and a door extension function provided at each landing on a plurality of floors, wherein a circuit for flickering the floor indicator of the indicator when the door is extended is provided. Is achieved by

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described below.

FIG. 1 is an electric circuit diagram of an embodiment according to the present invention, and FIG. 2 is a layout diagram of indicators generally provided in an elevator. In addition, as the initials of the reference numerals in the drawing, R is used for relays, F is used for flickers, and L is used for lamps. The contacts of relays and flickers are normally open contacts and normally closed contacts are respectively suffixed with a and b at the end of the reference numerals. did.

[0008] LFL is a floor indicator light of the indicator, RO
Pa is a normally open contact of a relay (not shown) that opens when the elevator is started to extend the door opening, and the extension is completed and the door closing command is issued, and FOP is a flicker device that operates when the normally open contact ROPa is closed.

Next, the operation of this embodiment will be described.

When the elevator is opened, the normally open contact ROPa is closed by a general prior art door open extension command, and the normally open contact ROPa is closed, and the P-ROPa-FOP-
N circuits are formed, and the flicker device FOP operates. As a result, the normally closed contact FOPb of the flicker FOP performs a flicker operation, a circuit of P-FOPb-LFL-N is formed intermittently, the floor indicator lamp LFL flickers, and the door is extended to the waiting passenger at the landing. Inform that Then, when the extension of the opening is completed, the normally open contact ROPa opens when the door closing command of the general prior art is generated, and the flicker device F
The OP ends the operation. This makes the flicker device FO
The normally closed contact FOPb of P is closed and P-FOPb-LFL-
N circuits are always formed, and the floor indicator LFL returns to the normal lighting state. Here, if there is a call on another floor, the elevator will service that floor according to a general prior art driving command.

[0011]

According to the present invention, since it is known that the waiting passenger at the landing is opening the door at another floor, it is easy to determine whether or not to wait for the elevator depending on the situation of the waiting passenger at this time. As a result, it is possible to reduce the frustration of waiting customers.
