BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of an electric enclosing blind embodying the present invention will be described below with reference to the drawings.

In the electric inclusion blind shown in FIG. 1, a horizontal blind 2 is included in a double glass sash 1. The head box 3 of the horizontal blind 2 is arranged in an upper frame 4 of the double glass sash 1, and a large number of slats 5 are suspended from the upper frame 4 via ladder cords.

An angle adjusting shaft 6 for adjusting the angle of the slat 5 is rotatably supported in the head box 3, and the angle adjusting shaft 6 is a motor arranged on one side of the head box 3. It is rotationally driven by 7 so that it can be rotated in the forward and reverse directions.

Therefore, when the motor 7 is operated and the angle adjusting shaft 6 is rotated, the angle of each slat 5 is adjusted in phase through the slat angle adjusting device and the ladder cord in the head box 3.

The upper part of the double glass sash 1 has 2
The solar cells 8a and 8b are attached indoors. When the solar cells 8a and 8b are irradiated with light, the electromotive force of the solar cells 8a and 8b causes the motor 7 to rotate normally or reversely.

The connection circuit between the motor 7 and the solar cells 8a and 8b will be described with reference to FIG.
8b is connected in parallel to the motor 7 and is connected to the motor 7 so as to have opposite polarities.

Limit switches 9a and 9b are connected in series to the motor 7 in the solar cells 8a and 8b, respectively. When the solar cell 8a is irradiated with light while the limit switch 9a is closed (conducting), the motor 7 is normally rotated and each slat 5 is rotated so that its convex surface is on the indoor side.

When each slat 5 is rotated until it becomes substantially vertical, the limit switch 9a is opened (not conducted), the operation of the motor 7 is stopped, and each slat 5 is moved in the same direction. The above rotation is prevented.

When the solar cell 8b is irradiated with light while the limit switch 9b is closed (conducting), the motor 7 is rotated in the reverse direction and each slat 5 is rotated so that its convex surface is located outside the room. It

When each slat 5 is rotated until it becomes substantially vertical, the limit switch 9b is opened (not conducted), the operation of the motor 7 is stopped, and each slat 5 is moved in the same direction. The above rotation is prevented.

At a position facing the solar cells 8a and 8b, a light unit 10 is disposed so as to contact the glass surface of the double glass sash 1, and as shown in FIG. Are provided with lamps 11a and 11b composed of halogen lights.

The lamps 11a and 11b are provided in the light unit 10 in a partitioned state,
The illumination light of the lamp 11a illuminates only the solar cell 8a, and the illumination light of the lamp 11b illuminates only the solar cell 8b.

The electrical configuration of the light unit 10 will be described with reference to FIG. 3. A first switch 12a is provided between the positive side terminal and the negative side terminal of the DC power source 14.
The first relay coil Ru is connected in series, and the second switch 12b and the second relay coil Rd are connected in series.

The first and second switches 12a, 12
b is provided on a wall surface or the like near the double glass sash 1 apart from the light unit 10. Between the positive side terminal and the negative side terminal of the DC power source 14, a normally open contact Rua that operates based on the excitation of the relay coil Ru,
The normally closed contact Rdb that operates based on the excitation of the relay coil 13b and the lamp 11a are connected in series.

Further, between the positive side terminal and the negative side terminal of the DC power source 14, a normally open contact Rda which operates based on the excitation of the relay coil Rd, and an operation based on the excitation of the relay coil Ru. The normally closed contact Rub and the lamp 11b are connected in series.

With this configuration, the first switch 1
When 2a is closed and the relay coil Ru is excited, the normally open contact Rua is closed and the normally closed contact Rdb is maintained in the closed state. Further, the normally open contact Rda is maintained in the open state, and the normally closed contact Rub is opened. Therefore,
The lamp 11a is turned on.

When the second switch 12b is closed and the relay coil Rd is excited, the normally closed contact Rdb is opened and the normally open contact Rua is kept open. The normally open contact Rda is closed, and the normally closed contact Ru is closed.
b is kept closed. Therefore, the lamp 11b is turned on.

Next, the operation of the electric inclusion blind constructed as described above will be described. When the first switch 12a is closed, the lamp 11a is turned on and the light is applied to the solar cell 8a. Then, the motor 7 is rotated in the normal direction, and the slat 5 is rotated so that its convex surface faces the indoor side.
When each slat 5 is rotated until it becomes almost vertical, the limit switch 9a is opened and the motor 7
Is stopped.

When the second switch 12b is closed, the lamp 11b is turned on and the light is applied to the solar cell 8b. Then, the motor 7 is rotated in the reverse direction, and the slat 5 is rotated so that its convex surface faces the outdoor side. When each slat 5 is rotated until it becomes substantially vertical, the limit switch 9b is opened and the operation of the motor 7 is stopped.

Also, by mistake, the first and second switches 12
When both a and 12b are closed, the normally closed contact Rdb,
Since both Rubs are opened, the lamps 11a and 11b
Both are turned off.

Therefore, the first and second switches 12a,
The solar cells 8a and 8b are not in a state of generating electric power due to an erroneous operation of 12b. The electric enclosing blind configured as described above can obtain the following operational effects. (1) By operating the first and second switches 12a and 12b, the motor 7 can be operated and the angle adjustment operation of the slat 5 can be performed. (2) By irradiating the solar cells 8a and 8b with light from the light unit 10, it is possible to supply power to the motor 7 and control the rotation direction of the motor 7. (3) In order to supply power to the motor 7, it is not necessary to supply power from outside the double-glazed sash 1. Therefore,
Since power wiring for supplying power from the outside of the double glass sash 1 is not necessary, the airtightness of the double glass sash 1 can be improved. (4) Since the signal line for transmitting the operation signal by the operation of the first and second switches 12a and 12b to the motor 7 is not required, the airtightness of the double glass sash can be improved. (5) The electric circuit housed in the double glass sash 1 includes the solar cells 8a, 8b, the motor 7, and the limit switch 9.
It can be simply constructed with only a and 9b. (6) The light unit 10 includes a relay and a lamp 11a,
It can be simply configured with only 11b. (7) Even if both the first and second switches 12a and 12b are closed by mistake, the simultaneous lighting of the lamps 11a and 11b can be prevented. Therefore, the lamps 11a and 11b
It is possible to prevent damage to the solar cells 8a, 8b or the motor due to simultaneous lighting of.

The above embodiment can be modified as follows. It is also possible to increase the electromotive force of the solar cell and, following the slat angle adjustment operation, drive the slat elevating device by the motor to perform the slat pulling up or down operation. -A lamp other than a halogen lamp may be used as the lamps 11a and 11b.
