Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a blind device that controls the incidence of outdoor light into a room.

2- In conventional blind extensions, the blind wings are connected with flexible connecting strings or bands, and the blind wings of the konera can be raised and lowered by pulling the operating string. The amount of incident C is adjusted by adjusting the angle.

In this conventional device (7), therefore, the adjustment of the incident party members is left to the human effort.

The present invention has been made for the purpose of obtaining a blind device that can perform highly advanced control of incident light, in which a plurality of blind blades are aligned vertically or horizontally of a window frame and held in a fixed position. The blind blades are rotatably supported and are characterized by being provided with a synchronous drive device that always rotates the vII number of blind blades at the same rotational phase. By automatically controlling the synchronization 1 vomiting device according to the actual brightness outside and inside the room, as well as the standard illumination level in the city, it becomes possible to automatically bring in outdoor light as needed, and it is possible to automatically bring in outdoor light as needed. By pre-inserting the frame into a unit, it is possible to provide a window with the function of adjusting the amount of incident light.

-3- The present invention will be described below with reference to an illustrated example.

In FIG. 1, the symbols / and λ indicate upper and lower window frame members, and a large number of blind blades 3, 3, . . . are supported in alignment between the window frame members 72.2.

Each blind wing piece 3 receives a force from a multi-source plate-shaped body extending above and below the window, a rotating shaft + 1 protruding from the top and bottom of the central part, and a bearing 6 attached to the window frame material/9.2, respectively. ．． It is rotatably supported. The installation interval of these blind wing pieces 3, 3... is ? , 3, but depending on the nature of the building, the above-mentioned gap may be set large, or the adjacent wing pieces 3 may be
, 3 may partially interfere with each other. Therefore, from the above configuration, each blind wing piece 3, 3 is rotated around the rotation axis II,...!
When the blade is rotated around If and the plate surface of each wing is parallel to the length direction of the window frame material/1.2, the opening is closed most often.
When used directly with window frame material /2.2, the window opening cannot be opened substantially.

Next, to explain the synchronized drive device for the upper blind blades 3, 3, etc., the rotary shaft 3 at the bottom of each blade is provided with a sprocket integrally with the pipe, and An idle sprocket q is rotatably mounted on the frame frame material in the middle of each suspension locket ff. And these sprockets t.

As shown in FIG. 3, a series of endless chains 10 are bent alternately between the blocks 9 and 9 so that the rotating direction of the sphere locket f is the same. It is designed to be rotated and pivoted by.

/ indicates the tension roll of the endless chain 10. According to this configuration, the sprocket has 9i! If the blind blades 3, 3... are oriented in the same direction when the chain 10t is spun as described above, then by driving the chain 10 by the motor, the chain 10 will always be in the same direction. Each blind/wing piece 3, 3, . . . can be rotated with a rotational phase of .

In addition, in Fig. 2, the symbol /11t is the cover of the 3-digit synchronization side III part, and /11t is a set of sliding 3 fitted in the window opening, or a recessed glass. Code/S
is a decorative board such as a ceiling board that covers the upper bearing 6.

The above forward/reverse rotation motor// is an appropriate one! Although the rotation can be driven by a mechanical control means, FIG. 6 shows a preferred control example.

The comparison calculation control circuit/6 includes an outdoor illuminance detector/7 including an appropriate optical sensor and an outdoor illuminance detector 7g as information signals.
Each illuminance signal from the ? A desired indoor setting illuminance signal, which can be arbitrarily set in a, is also input from the setting illuminance signal generator/de.

The functional configuration of the comparison calculation control circuit/B can be assembled according to the purpose using known automatic control technology of this type, but in general, considering automatic control only during daytime, the indoor illuminance is compared with the set illuminance. Then, when the indoor illuminance is low and the outdoor illuminance is compared with the set illuminance, and the outdoor illuminance is high, a drive energy signal is sent to the motor // in the blind blade opening direction via the servo amplification system 20. Once the indoor lighting signal reaches the set illuminance level, a stop signal (energy supply cutoff) is issued, and conversely, the illuminance inside the school is maintained above the set illuminance level by internal daytime lighting, etc. If the outdoor illuminance is below the set illuminance, the motor is rotated in the opposite direction to close the blind blades, or when the illuminance both inside and outside the house is below the set illuminance, the blind blades are fully opened. Additionally, if the response characteristics to the optical sensor are too good, the motor will make excessively small movements in response to pulse-like or disturbance (noise) changes in illuminance, especially near the set illuminance, causing the blades to flap. In such cases, a delay circuit may be added to the drive signal generation system in order to intentionally slightly deteriorate the response characteristics.

Furthermore, it would be more practical to consider automatic control over day and night, and to switch the set illuminance to different values during the day and night. In such a case, daytime and nighttime detection may be performed by using an electrical or mechanical timer used in a known automatic street light flashing device, or by using an outdoor light sensor's light receiving process. It detects the direction and also detects illuminance in the morning and evening (for example, 50
An electronic circuit that discriminates between day and night using t: as a threshold value may be used.

In addition, if the opening angle of the blind wing pieces is made to correspond to the motor rotation angle, and the motor Ih1 rotation angle is uniquely determined as the number of times according to each of the above-mentioned illuminance differences, the feedback circuit from the motor// It is also possible to control the rotation angle information via 811 circuit/6 and stop the motor when the blind blade reaches the required rotation angle. , create the opening and closing angle program of the blind wing 3.3 that will be drunk throughout the year according to the time of each day,
This is written in the memory of the microcomputer 2 as shown by the phantom line in the figure, and based on this, the control circuit 6 is operated via an appropriate interface (also phantom line 23). You may do so. In that case, an indoor/outdoor light sensor is not required.

Of course, since there is no need for a backup at night, if you only use automatic control during the day, if you simply adopt primary control such as always closing the blind blades at night, you can use a manual button to close the blades and a timer. Naturally, it is also possible to automatically shut down the vehicle.

Furthermore, if only two outside illuminance detectors are used,
In the morning, it would be a shame if the blinds in an east-facing room were left open too much, so leaving them half-open is also satisfying.

In other words, one sensor faces east, the other faces the opposite or in another direction, and the sum of the amount of light received by both is calculated and compared with the set illuminance for the morning. If the indoor illuminance is expected, the motor // is placed at a predetermined angular position to obtain the desired opening angle of the blind blades. this is,
It takes advantage of the natural phenomenon that when the sun is high, the sun is very bright in the direction of the sun, but not as bright in other directions. . A similar principle can be applied to Shoin Saiyo.

Other specifications are also available under the disclosure of the present invention. It is obvious to those skilled in the art that the technique can be used satisfactorily.

In the above embodiment, the glass/da is blind wing piece 3.3...
Although the glass is located on the outside of the room, the glass may be installed on the inside of the room, or the blind blades 3, 3, . . . may be provided between the double-layered glass. Furthermore, although the illustrated example is an example of on-site construction, it is also possible to provide a window unit having the function of adjusting the amount of incident light by incorporating the blind blades 3, 3 in advance into a unitized window frame.

Also, since the synchronous drive device in the above embodiment uses a chain, the sprocket is 11°g...Is there an idle sprocket in between? , ri..., but this idle sprocket was abolished and a rack group that meshed with all sprockets (gears) g, t... was installed, and this rack rod was moved forward and backward by a cylinder device etc. You can get the same functionality with either. Also, spulkerato wing pieces 3, 3...
It is clear that * may be arranged in the vertical direction.

1/θ- In short, the present invention is such that the blind blades, which are rotatably arranged in the vertical or horizontal direction of the window frame, are always rotated at the same rotational phase.
The amount of light incident on the window can be controlled over the entire window. In particular, if the rotational position of the blind blades is automatically controlled according to the actual brightness outdoors and indoors and the reference indoor illuminance, it is possible to incorporate outdoor light in ideal conditions as desired.
