Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a remotely controllable automatic opening/closing door in a home for the physically handicapped.

[Conventional technology]

Buildings where an unspecified number of people come in and out, such as public facilities such as hospitals and government offices, and department stores, are equipped with automatic doors that use infrared rays to allow people to enter and exit freely.

[Problem to be solved by the invention]

However, since the automatic opening and closing doors installed in the buildings mentioned above are intended for an unspecified number of people,
It is not suitable for private residences because it opens and closes automatically when someone approaches.

In addition, in the case of houses where people with physical disabilities live, not only the entrance door but also the sliding doors that separate the room from the hallway or the next room cannot be manually constructed. It is difficult and painful for people who use crutches to open and close the door.

However, even if you install an automatic door like the one mentioned above,
It may also be opened or closed without regard to the person's will, resulting in an invasion of privacy.

Therefore, an object of the present invention is to solve these problems and provide an automatic opening/closing door that can be automatically opened and closed based on the intention of the person in question.

[Means to solve the problem]

The present invention has been made to solve the above problems, and includes a remote control that instructs the opening and closing of the door, and a switch of the polarity of the DC voltage supplied to the overhead wire installed in the lintel based on the signal from the remote control. a controller equipped with a polarity switching means, a slider slidably brought into contact with the overhead wire, a motor driven by the DC voltage taken in through the slider, and a plurality of motors driven by the motor. An automatic opening/closing door is constituted by a pulley and the door, which is equipped with a switch means for cutting off a DC voltage supply path to the motor when power supply to the motor is no longer necessary.

[Effect]

With the above configuration, by instructing the door to "open" or "close" using the remote control, the polarity of the DC voltage supplied from the controller to the overhead wire will automatically switch, and the DC voltage will be connected to the door. Since the motor is applied through the slider that is attached to the door, the motor operates, and the rotational force of this motor is transmitted to the pulley that supports the door, allowing the door to run automatically. The provided switch means cuts off the DC voltage supply path leading to the motor when the door is fully opened or closed and comes into contact with a pillar or the like, so that the operation of the motor can be stopped.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 and 2.

Figure 1 shows an example of an automatically opening/closing door (sliding door) installed at the boundary with an adjacent room, where ■ is a remote control installed in the wheelchair 2, and 3 is a door installed in the lintel 4 based on the signal from the remote controller 1. A controller supplies a predetermined DC voltage to the overhead wires 5a and 5b (indicated by broken lines), 6 is a door that automatically moves when DC voltage is supplied to the overhead wires 5a and 5b, and 7 is a normal manual door (sliding door). be.

Although not shown on the remote control 1, there are an operation button "Open" for opening the door 6 and a "Close" operation button for closing it.
and is provided.

As shown in the figure, the controller 3 is attached to a wall 8 or a pillar 9 that separates it from the adjacent room, but the light receiving part that receives the infrared signal from the remote controller 1 is not only 3a shown in the figure, but also a light receiving part 3b installed in the next room (see FIG. ).

In addition to the light receiving sections 3a and 3b, the controller 3 includes a second
As shown in the figure, there is a transformer 11 that converts the voltage of a commercial power supply 10 into a predetermined voltage, a rectifier 12 that converts the output voltage of the transformer 11 into a predetermined DC voltage, and a DC voltage output from the rectifier 12. Polarity switching means 1 for switching the polarity of
3, this polarity switching means 13 has a microcomputer 14 that reads and processes the signal from the light receiving section 3a or 3b, a relay 15 controlled by this microcomputer 14, and this relay 15.
It consists of a quick action switch 16 that is activated in accordance with the movement of the contact piece.

This quick action switch 16 has two coils 1
6a, 16b and switching contacts al-bl, a2-b2.
It consists of three switch circuits having a3b3.

On the other hand, the upper part of the door 6 has sliders 17a and 17b which are slidably brought into contact with the overhead wires 5a and 5b, and the lower part thereof is driven by the DC voltage supplied through the sliders 17a and 17b. a motor 18 and a plurality of pulleys 19a 1
9b and a belt 20 that transmits the power of the motor 18 to the pulleys 19a and 19b, and switch means 21 on the left and right sides,
22 are provided.

These switch means 21 and 22 are provided in series in the DC voltage supply path leading from the slider 17b to the motor 18, as shown in FIG.
1 and a diode DI are connected in parallel, and the switch means 2
2 has a switch S2 and a diode D2 connected in parallel,
The diodes DI and D2 are coupled so that their polarities are opposite to each other.

The switch S1 cuts off the DC voltage supply path to the motor 18 when the door 6 is in the "open" state and comes into contact with the pillar 9 outside of FIG. This is to cut off the DC voltage supply path leading to the motor 18 and stop the operation of the motor 18 when it comes into contact with the pillar 9 in the center of FIG. 1.

The above is the configuration of the automatic opening/closing door of the present invention, and the operation thereof will be explained below.

The door 6 shown in FIG. 1 is in the "closed" state.
a (3b) and press the "Open" button provided on the remote controller 1.

Then, the controller 3 uses the microcomputer 14 to interpret and process the signal from the light receiving section 3a, and drives the relay 15.

When the relay 15 is driven, the relay contact moves from the contact A side to the contact B side, and the coil 16a of the quick action switch 16 is excited by the DC voltage output from the rectifier 12.

When the coil 16a is energized, contacts al, a2. a3
The contact pieces contacting the sides are contacts bl, b2, respectively.
It moves to the b3 side and is mechanically held.

Therefore, the polarity of the DC voltage supplied to the overhead wires 5a and 5b is reversed, and the current passes through the slider 17a and then flows to the motor 1.
8, the current flows through the diode D2, the switch S1, and the slider 17b in this order.

Accordingly, the motor 18 is driven, and the door 6 is opened by automatic running.

While the door 6 is running, the switch Sl of the switch means 21.22
, S2 are both in the ON state, but when the door 6 is completely opened and the switch S1 contacts the leftmost pillar 9,
The switch S1 is turned off, and since the diode D1 is provided in the opposite direction to the current, no current flows, and the motor 18 stops operating.

At this time, switch S2 is in the ON state, so
If the polarity of the DC voltage supplied to the overhead wires 5a and 5b is opposite to the polarity when the door 6 is opened, the current will flow through the slider 1.
7b1 diode D1, switch S2, motor 18, and slider 17a flow in this order, so motor 18 reverses and door 6
is closed.

To close the door 6, all you have to do is press the "Close" button on the remote controller 1. When the "Close" button is pressed, the microcomputer 14 works to change the contact piece of the relay 15 from the contact B side, which is opposite to the above, to the contact A. On the other hand, when the door 6 is opened first, the contact pieces of the quick action switch 16 are brought back to contact b.
l, b2. Since the coil 16b remains mechanically held on the b3 side, the coil 16b is excited.

When the coil 16b is energized, both contact pieces become contacts al.

a2. Since it is pulled back to the a3 side and mechanically held, the polarity of the DC voltage supplied to the overhead wires 5a and 5b is also reversed.

Therefore, the polarity of the DC voltage applied to the motor 18 is also opposite to that when the door 6 is opened, and the door 6 can be closed.

〔Effect of the invention〕

As explained above, an automatic door that opens and closes as described above is convenient because even people with physical disabilities can easily open and close the door with a simple remote control at hand. Since it can be opened and closed, it also has the effect of protecting privacy.
