Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vertical blind device of a variable blind angle type, which is additionally equipped with an automatic blind angle adjustment device.

[Conventional technology]

Hereinafter, a conventional vertical blind 100 of a variable blind angle type will be explained based on FIG. 8, which shows an example.

The vertical blind 100 has a plurality of fins 101 arranged vertically in a thousand rows.
In order to arrange the fins 01 in parallel, an upper fin support plate 102 and a lower fin support plate 103 are used.
A plurality of fins 10 are provided with the same number of fin upper rotation support parts 104 or fin lower rotation support parts 105 as the number of fins 01.
It has a structure that rotatably supports 1 all at once.

The fin upper support plate 102 and the fin lower support plate 103
The vertical blind is fixed with a side plate 106 and a side plate 107, and the vertical blind is installed with the side plate 106 and side plate 101 fixed at the place of use.

Furthermore, in order to keep the plurality of fins 101 parallel, the fin connecting portions 108 provided at both ends of the fin 101 in the direction of the rotation radius are connected by two wires 109. The wire 109 is connected to both ends 115 of a link 1100, which is an element of a mechanism that changes the blind angle, which is the angle of the fin.

7'l The mechanism for varying the angle is such that when the handle 111 is rotated, the rotation angle of the handle 111 changes to the handle axis 1.
The wire 109 is transmitted to the links 110 connected by the fins 12, and the wires 109 are pulled in accordance with the rotation angle of the links 110, so that the plurality of fins 101 rotate together.

Note that the handle shaft 112 is a bearing platen fixed to the side plate 6 in the same way as the bearing box 113 fixed to the side plate 106).
It is rotatably supported by 11411C.

The effect of vertical blinds is to limit visibility only in the direction along the blind angle. Therefore, unless you intentionally look into the room from outside the window with blinds installed, you will not be able to see what is going on inside the room, so it is effective to hide the room from the outside.] Adjust the blind angle to the direction of sunlight. This allows natural light to be brought into the room without blocking it. Furthermore, if the amount of solar radiation is too high, you can block some of the solar radiation by shifting the blind angle slightly from the direction of the solar radiation, and you can also use the reflection of the fins to indirectly bring natural light into the room. .

[Problem to be solved by the invention]

Traditionally, the blind angle was adjusted by the user determining the direction of solar radiation and the amount of solar radiation, and moving the handle by hand.
Since the direction of solar radiation and the amount of solar radiation change from moment to moment depending on the time of day and weather conditions, it is necessary to adjust the blind angle several times during the day, which takes time and effort since it is done every day.

Furthermore, since weather conditions change depending on the season and day, it may be necessary to make several adjustments to select the appropriate blind angle.

An object of the present invention is to provide a blind device that can solve the above conventional problems.

[Means to solve the problem]

A blind device according to the present invention is a vertical blind device of variable angle type, and includes a controller that outputs an output to control the blind angle according to time, an actuator that is controlled by the controller and drives the blind to a predetermined angle, and It is characterized by being equipped with a stone clock that transmits the time to the controller 2.

[Effect]

According to the present invention, it is possible to automatically adjust the blind angle continuously or intermittently depending on the time.

〔Example〕

FIG. 1 is a perspective view showing an embodiment of the present invention.

Since the direction α of solar radiation changes partially at time 1<, therefore, by setting the direction β of the blind 100 at the place where the blind is used, the blind angle θ appropriate for the direction α of solar radiation can be set at time 1Fc.

Therefore, as a means for automatically adjusting the blind angle, as shown in FIG. , consists of a controller 1 that outputs an appropriate blind angle setting (setting angle θ8), and an actuator 2 that makes the blind angle θ follow the setting angle θB outputted by the controller 1,
This is used by adding it to a conventional vertical blind.

Since the timepiece 10 and the actuator 2 are based on conventional technology, a detailed explanation will be omitted, and the controller 1 will be described.

In the example of the relationship between the time t and the appropriate blind setting angle θ8 patterned in the controller 1, the direction α of solar radiation is a function of the time t.

However, π is the circumference, t is the time in 24-hour system (unit: hour), and the direction of solar radiation α is, for convenience, the bundle O1 south is i,
The coordinates were assumed to be π for the west and -i for the north. Note that the coordinates in the embodiment are assumed to be for the northern hemisphere, and the signs may be reversed for the southern hemisphere.

In addition, the setting angle θ8 of the blind is the sum of the solar radiation angle θ1, the reflection angle θ of the blind, and the blocking angle for suppressing transmitted solar radiation and light, and as shown in FIG. 3, #B=θ , 10, 10, ... river...
(21. The solar radiation angle θ1 is calculated from the blind installation direction shown in Figure 2, in other words, the window direction β (the coordinates are the same as the solar radiation direction α) and the solar radiation direction α, as shown in Figure 3. It can be guided as shown.

The reflection angle θ of the blind is as shown in FIG.
If the angle obtained by subtracting the solar radiation direction α from the blind direction β is the angle that divides the solar radiation direction into two equal parts, then the angle that is the sum of the solar radiation angle θ1 and the reflection angle θ is the angle that divides the solar radiation indoors as shown in Figures 2 and 3. It means the blind angle in the direction 201 that leads most efficiently toward the direction 201.

By the way, the solar radiation blocking angle is an angle for shifting the set angle θB of the blind from the angle of (θ1+θm > max) to suppress the amount of solar radiation entering the room. The trigonometric function cosine (COS) is used in the example as a function that can suppress the amount of solar radiation in order to prevent the amount of solar radiation from getting brighter indoors around noon when the amount of solar radiation is high.

To, take. Therefore, in the morning after the optimum, according to equation (5)] (θ” 10 * ) max = 2 (0-H) + 2-
It becomes 4. When the morning light reflects off the blinds and enters the window at right angles, the room feels bright. To avoid this, the angle of incidence of light is changed to the maximum positive blocking angle, which is the optimum blind angle θ. ,t
becomes 0° and becomes 1 at t=τ+.

+2=3-x. If the light from the setting sun enters the window at right angles, the room becomes dazzling, so it is necessary to change the angle of entry of the light. Therefore, as in the morning, take the maximum positive angle. Therefore, the optimal blind angle θ. , t is θ.

, t=τπ+.

If we add the above equations (3) to (6) according to the right-hand side of equation (2), we get nothing other than A controller that can output the set angle θ8 is constructed.

The configuration of the controller is as shown in Figure 4.
/C, the differential operation between time t and the constant setting means 62 is performed by the differential operator 52, the output of the differential operator 52 is calculated by the multiplication operator 53, and the output of the multiplication operator 53 is applied to the distribution means 54.
The differential operator 55 performs a differential operation between the output of one of the distributed multiplication operators 53 and the blind direction β by the blind direction setting input means 50. The differential operation of the constant setting means 63 is performed by the differential operator 57, and the output of the other multiplication operator 53 distributed by the distribution means 54 is calculated by the cosine of the trigonometric function (
cos ) operator 58 and outputs Cog(2α), and outputs cos(2α) of the trigonometric function cosine (cos) operator 58 and the gain that can be set using the gain setting input means 51. It is assumed that multiplication is performed by a multiplication operator 59, differential operation is performed on the output of the differential operator 57 and the output of the multiplication operator 59 by a differential operator 60, and the set angle θ8 is outputted through the switch 61. The switch 61 is a means to set the blind angle to O at night and forcefully close the blind.For example, from 6:00 pm to 6:00 the next morning, the switch 61 is automatically opened and the blind angle is set to O. In order to set the blind angle to 0, the blind angle has a nighttime discrimination function, and a manual close setting means 1a is provided as shown in FIG.

In the first embodiment, the solar radiation blocking angle θ is set to the gain manually inputted by the variable manual means 51, and Vc
