Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sunshade device for general buildings, living quarters of ships, etc.

Traditionally, awnings used in general buildings and living quarters of ships have been raised and lowered manually during the day, so it is necessary to frequently check the sunlight before raising and lowering them, which takes a lot of effort. .

Therefore, an object of the present invention is to automate the operation of always maintaining the irradiation position of sunlight indoors at an arbitrary constant position.

For this reason, the present invention provides a sunshade that can be raised and lowered and manually operated, a drive device that can drive the sunshade up and down, and a photodetector that detects the position irradiated with sunlight on the inside of the sunshade. A light receiving device is provided in the lower part of the awning, and the opening height is set so that the three photodetectors are not illuminated at the same time. When the slit and the photodetector on the window side reach a predetermined level, the drive device raises the sunshade, and when the photodetector on the back side reaches a predetermined level, the drive device lowers the sunshade. a control device that controls the driving device to stop raising and lowering the sunshade when the central photodetector reaches a predetermined level, and controls the central photodetector to be irradiated with sunlight from the slit; The sunshade is raised and lowered so that sunlight reaches a predetermined position.

Therefore, it is possible to automate the operation of raising and lowering the awning during the day, without requiring human labor.
This can save you that effort.

Hereinafter, one embodiment of the present invention will be described based on the drawings. In Figures 1 and 2, inside a window 1 installed in a building or a living area of a ship, there is a sunshade 2 such as a blind that can be raised and lowered and that can be manually operated.
A motor 3 as a drive device capable of driving the sunshade 2 up and down is provided. A lateral slit 5 through which sunlight 4 passes is formed in the sunshade 2. At a suitable position in the room 6, that is, at the innermost position inside the window 1 where solar radiation can be allowed, a light receiving device 7 is movably arranged to detect that the sunlight 4 that has passed through the slit 5 has irradiated to this position. It is set up. As shown in FIG. 2, this light receiving device 7 includes three photodetectors 8 consisting of photoelectric converters etc.
A, 8B, and 8C are arranged in order from the window 1 side toward the back side. Note that the opening height of the slit 5 is set so that the three photodetectors 8A, 8B, and 8C are not irradiated at the same time. Further, the slit 5 is disposed at the lower part of the sunshade 2 so that the sunlight passing through the slit 5 and the sunlight from below the lower end of the sunshade 2 do not simultaneously irradiate the light receiving device 7. A control device is provided between the motor 3 and the light receiving device 7 to control the sunlight 4 from the slit 5 to irradiate the central photodetector 8B of the light receiving device 7.

The above control device includes a motor side control circuit 10 shown in FIG. 3 and a light receiving device side control circuit 20 shown in FIG.
It consists of In FIG. 3, reference numeral 11 is a changeover switch that is connected to a power source and switches the raising and lowering operation of the sunshade 2 between manual side a and automatic side b, and 12 and 13 are connected to the manual side a of the changeover switch 11 via a stop switch 14. Push-button switches 15 and 16 for raising and lowering connected to are first and second opening/closing contacts connected to the automatic side of the changeover switch 11.
17 is a first electromagnetic switch connected to the lift push button switch 12 and the first switching contact 15; 18;
is a second electromagnetic switch connected to the push button switch 13 for lowering and the second switching contact 16, and the self-holding contacts 17a and 18a of the first and second electromagnetic switches 17 and 18 are for raising. The push button switches 12 and 13 for lowering are connected in parallel, and the first and second electromagnetic switches 17 and 18 have forward and reverse contacts 17b and 18b, respectively.
have. 19A is a first limit switch that is connected to the first electromagnetic switch 17 and is opened when the sunshade 2 reaches the upper limit position, and 19B is connected to the second electromagnetic switch 18 and is a first limit switch that is opened when the sunshade 2 reaches the lower limit position. This is a second limit switch that is opened at times.

In FIG. 4, 21A, 21B, and 21C are amplifiers that amplify the output from each photodetector 8A, 8B, and 8C, and 22A, 22B, and 22C are level detectors connected to each amplifier 21A, 21B, and 21C, respectively. be. Reference numerals 23A and 23C are self-holding relay circuits that are set by the output of the level detectors 22A and 22C and reset by the output of the level detector 22B, respectively, and drive the self-holding contacts 15 and 16 of the motor control circuit 10, respectively. Level detectors 22A, 22B, 22C are photodetectors 8
The outputs from A, 8B, 8C are sent to amplifiers 21A, 21
It is designed to output when a predetermined level is reached via B and 21C.

Next, its operation will be explained. First, with the changeover switch 11 set to manual side a, operate the push button switches 12 and 13 for raising and lowering to close the electromagnetic switches 17 and 18, and drive the motor 3 for driving the sunshade. Then, the sunshade 2 is raised or lowered so that the sunlight 4 from the slit 5 illuminates the central photodetector 8B, and is moved to the H position, for example, and then stopped using the stop push button switch 14. Thereafter, the changeover switch 11 is switched to the automatic side b. As time passes, the sun becomes higher, and sunlight 4 illuminates the photodetector 8A on the window side.
The output of the level detector 22A activates the first self-holding relay circuit 23A, which closes the self-holding contact 15, activates the first electromagnetic switch 17, and causes the motor 3 to raise the sunshade 2. This operation continues until the self-holding of the relay circuit 23A is reset by the level detector 22B of the central photodetector 8B, and the sunshade 2 is raised to position the slit 5 at the H' position and the central light The motor 3 stops when sunlight 4 enters the detector 8B.
Moreover, when the sun becomes low and the photodetector 8C on the back side is illuminated, the operation is opposite to the above. The sunlight 4 that has passed through the slit 5 is detected by the photodetector 8.
The sunshade 2 is stopped in a state where B is irradiated, and the sunshade 2 is automatically operated so as to irradiate a predetermined distance inside the sunshade 2.

As described above, according to the present invention, conventionally, for example, when working at a desk, when the sun gets low, the sunlight penetrates deep into the room, making it difficult to work. However, automation eliminates this troublesome work of raising and lowering the sunshade, making it possible to work more comfortably. What's more, the height of the awning can be finely adjusted using three photodetectors placed from the window side to the rear so that sunlight irradiates to a predetermined position, achieving the optimal sunlight irradiation condition. be able to.
