Abstract

PURPOSE:To obtain a push button device for pedestrians which does not require a commercial power source by supplying a DC power source for lighting of a handled indicator lamp to a switch part. CONSTITUTION:The DC signal of a handling indicator lamp lighting signal PL 2 is supplied as the power of a switch part 5 consisting of an electronic circuit. That is, since the switch part 5 consisting of the electronic circuit is operated when a handling indicator lamp 3 is lit, its power is used to eliminate a need to provide another power supply part and a need to receive another commercial power. Thus, the push button device for pedestrians which does not require the commercial power source is obtained.

PB in the upper row indicates that the handling indicator light 3 of the pedestrian push button device is in a lit state.

The state on the push button switch of the pedestrian push button device is shown.

Next, the operation of the pedestrian push button device constructed in this way will be explained with reference to FIGS. 2 and 4. Second
In the figure, a push-button switch 1 is used by a pedestrian who wants to cross a crosswalk to transmit a crossing request to a push-button traffic signal controller 4. Normally, it is in the "closed" state, but when it is pressed, it is in the "open" state. Become.

The confirmation indicator light 2 informs pedestrians that the push-button traffic signal controller 4 has accepted the crossing request.It is off when the indicator is not on, and lights up when the indicator is on. Please wait" appears. In addition, when one pedestrian is given the right of way and the pedestrian signal light on the crossing side turns green, it goes out. The timing is shown in FIG. In addition,
The lighting control circuit and drive circuit described above are mounted on the push-button traffic signal controller 4, and only the confirmation indicator light 2 is disposed on the pedestrian push-button device.

The handling indicator light 3 is provided to allow pedestrians to press the push button. It lights up when the button is not set to G) and the words ``Press the button'' appear. The timing is shown in FIG. Further, the lighting control circuit and the drive circuit are mounted on the push-button traffic signal controller 4, and only the handling indicator light 3 is arranged in the pedestrian push-button device.

Next, a second conventional example will be explained with reference to FIG. This figure is a block diagram of a second conventional example, which differs from the first conventional example shown in FIG. Another feature is that it is equipped with a touch panel 6 that detects the touch of a pedestrian's finger, and a power supply section 7 that converts commercial power into direct current. Since the rest remains the same, the same components are given the same reference numerals and their explanations will be omitted.

The operation of the second conventional example configured as described above will be explained. In FIG. 3, the switch unit 5 is a proximity switch composed of relay contacts that utilizes the fact that when a pedestrian touches the touch panel 6 with a finger, the capacitance between the touch panel 6 and the ground changes. It is configured so that when a pedestrian touches it with a finger while it is in the "closed" state, it becomes "open".

The power supply section 7 receives the commercial power supply and connects the switch section 5 described above.
Supplies DC power to the The confirmation indicator light 2 informs pedestrians that the push-button traffic signal controller 4 has confirmed the contact of the pedestrian's finger.It is off when the contact is not confirmed, and turns on when the confirmation is confirmed and says ``Please wait.'' The letters stand out. In addition, the signal light for pedestrians on the intersection side turns off when it turns green. The lighting control circuit and drive circuit are mounted on the push-button traffic signal controller 4, and the pedestrian push-button device has only a confirmation indicator light. The handling indicator light 3 is an indicator light that allows pedestrians to touch the touch panel 6 with their fingers. It lights up when in any other state and the words ``Press the button'' stand out. The lighting control circuit and drive circuit are mounted on the push-button traffic signal controller 4, and only the handling indicator light 3 is disposed on the pedestrian push-button device.

(Problem to be Solved by the Invention) However, in the above-mentioned second conventional example, the switch section 5
Since it was constructed from an electronic circuit, there was a problem in that a power supply section 7 was required to supply it.

Further, in order to receive power from a commercial power source, additional wiring work, etc. is required, and there is a problem that it is difficult to replace the first conventional example with the second conventional example.

The present invention solves the above problems and provides a pedestrian push button device that does not require commercial power.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention supplies a DC signal of the handling indicator lamp lighting signal (PL2) as a power source to a switch section configured with an electronic circuit.

(Function) With the above configuration, the switch section composed of an electronic circuit can
Since it is a device that operates when the handling indicator light is on, if the power source is used, there is no need to install a new power supply section, and therefore there is no need to receive a new commercial power source.

(Example) An example of the present invention will be described with reference to FIG. In the same figure, the difference between this embodiment and the second conventional example shown in FIG. be. Since everything else remains the same, the same components are given the same reference numerals.
The explanation will be omitted.

The operation of the pedestrian push button device configured as described above will be explained. In FIG. 1, the confirmation indicator light 2 and the handling indicator light 3 are composed of a plurality of LEDs and a current-limiting resistor, and are turned on by the lighting signals PLI and PL2 from the push-button traffic signal controller 4. . The lighting signal is between PLO and PLI when lighting the confirmation indicator light 2, and between PLO and PLI when lighting the handling indicator light 3.
A DC voltage is applied between LO and PL2, respectively.

The switch section 5 configured with an electronic circuit is a proximity switch that utilizes the fact that when a pedestrian touches the touch panel 6 with a finger, the capacitance between the touch panel 6 and the ground changes, and operates using direct current. The switch unit 5 receives lighting signals PLO and PL2.
Therefore, when the handling indicator light 3 is lit.

Direct current is supplied to the switch section 5. That is,
When the handling indicator light 3 indicating "Press the button" is on, the switch section 5 is in an operating state and can accept or accept a pedestrian's crossing request. Handling indicator light 3
When the lights are off, there is no need to respond to pedestrian crossing requests.

During that time, there is no problem even if the switch section 5 does not operate. In other words, it is only necessary to apply the DC voltage to the switch section 5 when the handling indicator light 3 is lit.

(Effects of the Invention) As explained above, according to the present invention, by supplying the DC power for lighting the handling indicator light to the switch section,
No power supply required. Therefore, since there is no need to newly receive commercial power, a mechanical push button switch can be easily replaced with a push button using a touch panel.
