Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a blind opening/closing device.

[Prior art] Conventionally, this type of blind opening/closing device has a manual type and an f11 type.
In the manual type, operating means for opening and closing the soundboard connected to the moving cord are provided at predetermined intervals in the vertical direction, and a person operates the operating means to open and close the wing plates. It was structured like this. In addition, the electric method uses a motor that drives the Makki blade plate by a commercial power supply, and a motor that controls the other motor. A control switch was provided, and the blades were opened and closed by operating the control switch.

[5! Problems that Ming attempts to solve As described above, when the conventional blind opening/closing device is a manual type, opening and closing the blind requires effort and is very troublesome. Furthermore, since electric systems use commercial power, they require a transformer, have many components, and have complicated wiring, making blind installation a hassle.

Furthermore, in both types, the operating means and control switch cannot be provided at a location away from the blind, and it is troublesome to have to go close to the blind each time it is opened or closed.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the blind opening/closing device of the present invention has an opening/closing body that moves a movable cord to open and close the blades, and a blind opening/closing device connected to the opening/closing body, A DC motor for operating the opening/closing body, a drive circuit for driving and controlling the DC motor, a dry battery as a power source for driving the DC motor and the drive circuit, and an opening/closing switch for controlling the opening and closing of the blades. A transmitter that transmits a control signal based on the operation of the open/close switch, and a receiver that is connected to the drive circuit and receives the control signal and controls the DC motor via the drive circuit are installed. I'm here.

[Function] When opening and closing the blinds using the 4M configuration, a control signal is transmitted by operating the open/close switch of the transmitter,
A receiver receives the signal and activates a drive circuit to rotate the DC motor. The opening/closing body is operated by the rotation of this DC motor, and the moving cord is moved up and down based on the operation of (a) to open and close the vane.

[Embodiment 1] Hereinafter, an embodiment embodying the present invention will be described with reference to FIGS. 1 and 2.

The blind 5 has a blind frame 6 on its upper part, and the blind frame 6 has corners 7 formed at the left and right ends and at the center of the bottom. Also blind frame 6
A drive @9 is rotatably supported inside the , and a rotating plate 10 is provided at the left and right ends and the center of the drive @9. 119 and rotated together with its drive shaft 9.

Two moving cords 12 are attached to both ends of these rotating plates 10.
The upper ends of the movable cords 12 are respectively fixed, and the movable cords 12 are inserted into grooves 7 at the bottom of the blind frame 6 and extend downward.

A plurality of vanes 13 are arranged below the blind frame 6, and these vanes 13 are connected to the moving cord 12.
are attached to and connected to each other by tape 14. The blades 13 are moved up and down by the vertical movement of the moving cord 12 to move the vanes 13 between a closed state where they overlap each other and a closed state where the vanes 13 are horizontal. Note that the moving cord 12 and the rotating plate 10 are arranged at the left and right ends and the center of the wing plate 13, respectively.

A motor gear box 17 is connected to the left end of the drive @9 via a joint 16. The motor gear box 17 is formed of a gear box 17a and a DC motor 17b, and the gear box 17a decelerates the rotation of the DC motor 17b and transmits it to the drive shaft 9. The drive circuit 18 that drives and controls this DC motor 17b is the DC Tanabata 17b.
and is connected to the DC Tanabata 17b.

A dry cell battery 19 is provided as a power source for driving the DC motor 17b and the drive circuit 18, and is connected to the drive circuit 18.

Further, a light receiving section 21 of a receiver 20 connected to the drive circuit 18 is attached on the left end side surface of the blind frame 6, and this light receiving section 21 receives a control signal P transmitted from a transmitter 24, which will be described later. Then, the receiver 20 drives and controls the drive circuit 18 based on this control signal P.

Furthermore, a stopper 22 is provided at the center of the groove 7 at the bottom left end of the blind frame 6 to restrict the rotation 171m of the rotation plate 1Q.

The motor gear box 17, drive circuit 18, dry cell battery 19, and receiver 20 are housed within the blind frame 6.

A transmitter 24 that transmits a control signal P to the receiver 20 is provided separately from the blind 5. This transmitter 24 includes an opening/closing switch 24a for controlling opening/closing of the blind 5;
24b, and its open/close switches 24a, 24b
After discovering the operation of , he sends out the open signal Pa and the open signal PB, which are the anti-crime Shintan P, using infrared rays. Note that the drive circuit 1
8 and the receiver 20 are each constructed from one integrated circuit, and are designed to reduce power consumption.

The operation of this embodiment configured as described above will be explained.

When closing the blind 5, when the close switch of the transmitter 24 is pressed, the transmitter 24 transmits a close signal Pa, and the light receiving section 21 attached to the blind frame 6 receives this close signal Pa. The device 20 drives and controls the drive circuit 18 based on the close signal Pa to rotate the DC motor 17b counterclockwise in FIG. and DC motor 1
The rotation of 7b is decelerated by the gear box 17a and transmitted to the drive shaft 9, which rotates the drive shaft 9 and the rotary plate 10 fixed to the left and right ends and the center of the drive shaft 9 in the anti-+15 meter direction. make it move. Since the moving cord 12 is attached to the rotating plate 10, as the rotating plate 10 turns iFJ+, the moving cord 12 on the right side in FIG.
move downward, so the wing plate 13 fixed to the moving cord 12 turns counterclockwise. J+L, blind 5 is moved in the closing direction.

Here, while the close switch 24b of the transmitter 24 is pressed, the close signal Pa is continuously transmitted from the transmitter 24, the vane plate 13 continues to rotate counterclockwise, and the rotating plate 1
0 is rotated approximately 9o degrees, the blind 5 is completely closed,
Further, the left end of the rotating plate 10 comes into contact with a stopper 22 provided at the bottom of the left end of the blind frame 6. and 1
If the rotary plate attempts to rotate further in the counterclockwise direction, a clutch (not shown) in the gear box 17a begins to slip, causing the DC motor 171 to rotate idly. Therefore, the rotating plate 10 does not rotate any further.

Further, the amount by which the blind 5 is closed is determined by canceling the suppressing operation of the closing switch of the transmitter 24, so that the transmission of the closing signal Pa is stopped, and the drive circuit 18 by the receiver 20 is thereby stopped.
Since the drive control of the N plate 13 is stopped and the rotation of the DC motor 17 and the blade plate 13 is stopped, the inclination angle of the N plate 13 can be adjusted as desired.

Next, when opening the blind 5, when the open switch 24b of the transmitter 24 is pressed, the transmitter 24 transmits an open signal Pb, the light receiving section 21 receives this open signal Pb, and based on this signal, the drive circuit 18 to drive and control the DC motor 17
b is rotated clockwise, and the drive shaft 9 and rotating plate 10 are rotated clockwise. This rotation of the rotating plate 10 causes the first
The moving cord 12 on the right side of the figure is moved downward, the moving cord 12 on the left side is moved upward, and the vane 13 is rotated clockwise so that the blind 5 is heard. Similarly to the case of closing the blind 5, it can be arbitrarily adjusted by releasing the suppressing operation of the switch.

The present invention is not limited to the embodiments described above,
Various changes can be made without departing from the spirit of the invention.

For example, in this embodiment, the signal transmission method uses infrared rays, but a transmission method using sound waves or electromagnetic waves may also be used.

[Effects of the Invention] With the above configuration, the present invention can perform the opening/closing operation of the blind,
By operating the open/close switch on the transmitter, it can be easily operated even from a distance from the blind.Also, by using dry batteries as the power source for the drive circuit and receiver, the configuration can be simplified and wiring can be simplified. is also very easy to do.
