Description

[Detailed Description of the Invention] This invention relates to an improvement of a device for registering elevator hall calls.

It is well known that in an elevator, a hall call is registered and a car can be called by pressing a hall button installed at the hall. When a hall call is registered, the registration light built into the button lights up to display the registration of the call. When the car arrives at the floor in response to this call, the hall call is canceled and the registration light is turned off.

However, this is only for healthy passengers, and is inconvenient for visually impaired people. Therefore, an electromagnetic holding type push button switch is used as the hall button. When this landing button is pressed, a built-in coil is energized and the button remains in the pressed position.
When the car arrives and the coil is deenergized, the spring force causes the button to return to its original position. Thereby, if the passenger touches the button, he or she can easily know the arrival of the car.

Now, if two or more baskets are installed in parallel, the first
As shown in the figure, a landing button 3 is usually installed on the wall between the entrance 1 of the first car and the entrance 2 of the second car. When this landing button 3 is pressed, a common landing call for cars No. 1 and No. 2 is registered. and,
When either car arrives in response to this hall call, the hall call is canceled. Therefore, even if the above-mentioned electromagnetic hold type push button switch is used for the hall button 3, it is impossible for a visually impaired person to know which car responded by its return operation. It is.

This idea improves the above-mentioned problem, and even in the case of a common landing button for multiple cars,
To provide an elevator hall call registration device that can easily notify which car is arriving by touching it.

An embodiment of this invention will be described below with reference to FIGS. 1 to 4.

In Figures 2 and 3, 4 is the front board of the hall button 3, 5 is the up call button, 6 is the down call button,
7 and 8 are unit buttons that are divided into two parts of the up call button 5 and have "left" and "right" written in Braille respectively.Button 5 is fingertip-sized so that when pressed, unit buttons 7 and 8 operate simultaneously. It is made up of an area of 7a and 8a are respectively connected to the unit buttons 7 and 8. Movable cores 7b and 8b are coils that magnetize the movable cores 7a and 8a, respectively. 7c and 8c are movable contacts and fixed parts attached to the movable cores 7a and 8a, respectively. A contact consisting of a fixed contact provided in the
7d and 8d are movable iron pieces fixed to the ends of movable iron cores 7a and 8a, respectively; 7e and 8e are fixed iron cores provided in fixed parts and facing the movable iron pieces 7d and 8d;
Return springs 7f and 8f provide a force for returning the movable cores 7a and 8a to their return positions. Note that the down call button 6 is also configured in exactly the same manner.

In Fig. 4, (+) and (-) are DC power supplies, 10 is a landing up call registration relay that, when energized, registers, for example, a 1st floor up-hall call, and 11 is activated and turned off immediately when energized. When pushed, a certain time limit (e.g. 4 seconds)
A time relay that returns later, 11a is its normally open contact, 12 is also a time relay, 12a is its normally open contact, 13a to 13d are used when either No. 1 or No. 2 receives a call to the landing on the first floor. A stop command relay contact that opens when it is decided to stop and closes when the above-mentioned call is cancelled; 14 is a door control relay contact that opens when issuing a door opening command for Unit 1 and closes when issuing a door closing command; 15 is the same door control relay contact for Unit 2, 16a and 16b are the car position contacts that open when Unit 1 is on the first floor, 16c is the car position contact that also closes, and 17a and 17c are the same 2
This is the car position contact for the car.

Next, the operation of this embodiment will be explained.

It is now assumed that the cars of both Units 1 and 2 are not on the first floor. At the landing on the first floor, a passenger presses the landing button 3.
When you press the up call button 5, the unit buttons 7 and 8
are pressed together, and contacts 7c and 8c are closed together. (+)-7c-7b-16b-17b-10-
(-) and (+)-8c-8b-16a-17a-
The hall up call registration relay 10 is energized by the circuit 10-(-). At the same time, coils 7b and 8b
Since the movable iron pieces 7d and 8d are attracted to the fixed iron cores 7e and 8e, respectively, the unit buttons 7 and 8 are held at the pressed positions. Passengers read the braille on unit buttons 7 and 8 and keep their hands on them as they wait for the car to arrive.

When Unit 2 approaches the first floor, car position contact 17
a, 17b are open, and contact 17c is closed. When the second machine decides to stop in response to this call, the stop command reloo contacts 13a to 13d are opened. As a result, the coil 8b is deenergized, so
The right unit button 8 is returned to its original position by the force of the spring 8f, and the contact 8c is opened. On the other hand, when the contact 17c is closed, the door of Unit 2 is closed and the door control relay contact 15 is closed, so (+)-17c-
15-11-(-) circuit causes time relay 11
is energized, and the contact 11a is closed. Therefore, the coil 7b remains biased, and the left unit button 7 remains pressed.

Now, by returning the right unit button 8 and keeping the left unit button 7 in operation, the passenger can return to the right unit button 8.
It is easy to know that Unit No. 2 has arrived, and after confirming through the announcement that the door is open (diagram omitted), passengers quickly board Unit No. 2. When the door open command is issued to Unit 2, door control relay contact 15
is opened, and since the stop command relay contact 13c is open at this time, the time relay 11 is deenergized,
It returns after 4 seconds and the contact 11a opens. As a result, the coil 7b is deenergized, and the left unit button 7 is also returned to its original position by the force of the spring 7f, and the contact 7
c is open. In addition, the boarding up call registration relay 1
0 is deactivated.

In addition, the time limit of the time limit relay 11 is set by pressing the unit button 8.
It is set to the time required for the passenger to reliably board the car after the car returns.

It goes without saying that the same is true when the No. 1 car responds to an up call from the landing on the first floor, and the same explanation can be given to a down call as well.

The example shows the case where two cars are installed in parallel, but in the case of three cars, the unit buttons 7 and 8 are set to 3.
A similar implementation is possible by dividing.

As explained above, in this invention, the hall button is composed of unit buttons placed adjacent to each other, and these unit buttons are pressed at the same time and held in their position to register a hall call, and when one of the cars is pressed. When the car responds, the unit button corresponding to that car is restored and the other unit buttons are held as they are, so even if the passenger is visually impaired, he or she can still touch the platform button. If one of the baskets has arrived, it can be easily notified.
