Description

[Detailed Description of the Invention] Technical Field of the Invention - This invention provides an escalator that can be used by wheelchair users, etc.
The present invention relates to a passenger conveyor such as a moving walkway, and particularly to a passenger conveyor that automatically notifies necessary operating procedures as the passenger conveyor moves.

The depth dimension of the steps of a conventional passenger conveyor, such as an escalator connecting the upper and lower floors, is around 400 mm, which is sufficient for general passengers to use, but it is not suitable for people with disabilities using wheelchairs. In such cases, wheelchairs cannot be used because the space reserved for them is large.

Therefore, in the past, one or more specific steps with a depth dimension that allows the wheelchair to get on the platform are installed at arbitrary locations in the step row, and the steps are used to transport the wheelchair user. An escalator has been proposed, which is a known technique in Japanese Patent Publication No. 41555/1983.

Such an escalator is simply a general escalator with additional control means for utilizing special steps.

However, in general, it is rare to use a specific step, and ordinary passengers do not know how to respond, and even more so when an inexperienced wheelchair user tries to use an escalator, it is difficult to know how to operate it. I had a problem that I didn't understand.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and provides the following precautions when using a specific step in a passenger conveyor that has a specific step that can be used by wheelchair users in addition to the normal steps.
A means for broadcasting operating instructions, etc. is provided, and this broadcasting means automatically broadcasts operating procedures when using specific steps and precautions for general users when operating a wheelchair, and allows users to handle the product. It provides a passenger conveyor.

Next, the operation of this embodiment drawn as described above will be explained.

Now, assuming that the escalator is normally operated in the upward direction, the wheelchair operation relay /l, the wheelchair operation start command relay 17, and the interlock relay /g are deenergized, and the stop command relay 16 is activated (4→- Contact 1Sd-Contact i
It is energized by the closed circuit of gd-relay/6-(to).

Therefore, the operating contactor/- is energized by the m circuit of the 0→-stop switch S/- contact/Ab- contact/, 2e-: I contactor l-1 (c), and the contact 7. ,
By closing 2c, the electric motor ll and the brake coil llI
is being powered. Therefore, the electric motor // is driven and the escalator is in normal operation.

When the wheelchair user presses the switch S3 to use the escalator in the operating state of the escalator, 0→-switch s3-contact/, 2d-relay/! ;-
An m circuit of H is formed, and the wheelchair driving relay IS is energized. This causes normally open contacts /ja, /jb +/&

amplified by speaker 9. By sending signals to /, 0 and driving Subikawa, /θ, a notice is broadcast to general passengers, and the wheelchair user is also advised to wait until the Fi specific step 1 or the boarding gate.

When the specific step q reaches the multiplier [2I], the limit switch SS opens and the normally closed contact lSd is open, so the stop command relay 76 is deenergized and its normally open contact /

When the escalator stops, the specific step q stops at a position slightly past the limit switch St, so the limit switch Sj closes again, and (1) - limit switch SS - limit switch SA - relay l The stop command relay 76 is energized again in the closed circuit of Mi-(→), its normally open contacts /Aa and /Ab+/Ac close, and its normally closed contact /Ad opens to prepare for the next operation.

In addition, even if the normally open contact /Aa opens due to the deenergization of relay /6, the normally closed contact 1gb is closed, so the wheelchair driving relay /l is (1) - contact /gb - contact 1ka - relay / ,! ---(-1 is self-held by the circuit, and relay 76 is energized, (g) - contact / loop a

Gives a second broadcast content selection command, selects and outputs broadcast content that shows the wheelchair user how to insert or restart the speaker,
From 10 onwards, boarding guidance and operating instructions for restarting the vehicle will be broadcast. At this time, the normally closed contact 2.2b is opened, so the relay 2/ is deenergized and the first broadcast content selection command is no longer issued.

When a wheelchair user presses the wheelchair operation switch SII while riding on a specific stepper by himself or with an attendant, (1)

Then, by closing the contacts /Ja~/.2c The electric motor//and the plagicoil/IK are supplied with power, and the escalator starts operating.

On the other hand, when normally closed contact /7b is closed, (''→-contact /

Further, by opening the normal Mm point /gci of the interlock relay /g, the operation of the limit switch S6 at exit is enabled. Furthermore, when the 1711 contact/zae is closed, the (g)-contact/je-contact/. 2h-contact/g
Relay λ3 is energized by the closed circuit of e-relay, 23-(→), is self-held by its normally open contact 3b, and issues the third broadcast content selection command by closing the normally open contact 2Ja.

A broadcast content selection command is given to the broadcast content storage unit/9,
As a result, the broadcast content storage unit lq selectively outputs guidance for wheelchair users, operating procedures for returning to normal operation, and precautions for general users due to escalator activation, and outputs information on the amplifier. Broadcast from speakers “y, io” via 〇.

Also, when the normally open contact /je is opened, the time relay 2da is deenergized, so after a certain period of time, the time relay 2da is deenergized.
The fall time contact ta of DA is opened, relay 2& is deenergized, and the fourth broadcast content selection command is canceled.

The operating contactor /, 2 is energized in the closed circuit of c), and the contactor /λ is self-held by the contact /2e, and the electric motor // and the brake coil l are closed by the contact /, la-/2c. This will supply power to the escalator and return the escalator to normal operation.

Note that this invention is applicable not only to escalators but also to passenger conveyors such as moving walkways.

As described in detail, the present invention provides an automatic broadcasting system that automatically broadcasts information every time a wheelchair user performs an operation to operate a passenger conveyor by entering a specific step. Since the system broadcasts the next operation procedure and caution messages in order, even inexperienced wheelchair users can operate the passenger conveyor with confidence and without errors. It is expected that it will be used more efficiently. In addition, there is no confusion for general users due to sudden stops while using the passenger conveyor.
This has the advantage of being able to be dealt with in advance.
