Description

The present invention relates to a vertical blind in which slats are suspended and supported in parallel in two rows in the front and rear.

In the vertical blind, the slats are suspended and supported so as to be adjustable in angle from a large number of runners that are movably supported in the hanger rail. In a general vertical blind, the amount of light taken into the room is adjusted by pulling out the slats along the hanger rail and adjusting the angle of the slats manually or electrically.

For the slats of the vertical blinds, drape fabric with light-shielding property and lace fabric with semi-transparency are used. Then, for example, there is a vertical blind that appropriately prevents light leakage when adjusting the tilt angle of slats that are alternately suspended and supported and have different rotation speeds using an external operation terminal such as a remote controller (. See Patent Document 1).

The calculation unit 15a calculates the guidance position of the runner 4 from the rotation amount of the drive shafts 10a and 10b detected by the guidance encoders 13a and 13b.

The control unit 15 is a memory unit 15b such as an EEPROM that stores a calculation unit 15a such as a microcomputer and table information describing an interference possible area according to the tilt angle of the slats 5a and 5b and a control program of the slats 5a and 5b. And a motor drive unit 15c.

The calculation unit 15a calculates and controls the tilt angle of the slats 5a and 5b and the rotation amount of the drive shaft 8 and the tilt shaft 5 based on the table information and the control program stored in the memory unit 15b. Further, the calculation unit 15a determines whether or not the reception unit 18 receives the angle adjustment signal from the remote controller 16. The first tilt angle detection unit 15d is the first tilt encoder 1
The tilt angle of the first slats 5a is detected based on the rotation amount detection signal from 2a. The second tilt angle detection unit 15e detects the tilt angle of the second slats 5b based on the rotation amount detection signal from the second tilt encoder 12b.

When it is assumed that the determination unit 15f receives the angle adjustment signal from the remote controller 16 and controls the rotation of the first slat 5a or the second slat 5b based on the angle adjustment signal, the first tilt angle detection unit 15d and the determination unit 15f First slats 5a acquired from the second tilt angle detection unit 15e
And, based on the tilt angle of the second slat 5b, it is determined whether or not the second slat 5b has an interferable region. Specifically, the determination unit 15f refers to the table information stored in the memory unit 15b and prepared in advance, or uses a calculation formula using numerical values such as the tilt angle and pitch interval of the slats 5a and 5b defined in advance. The determination can be made. When it is determined that the determination unit 15f passes through the coherent area, the determination unit 15f controls the first slat 5a or the second slat 5b to be rotationally controlled so as to be out of the coherent area. The tilt angle control unit 15g controls the rotation of the first slat 5a and the second slat 5b based on the instruction from the determination unit 15f.

The receiving unit 18 has an RF module 18a which is an electronic part having a wireless communication function with a mobile terminal or the like, and an infrared receiving unit 17b which performs infrared communication with the remote controller 16. Receiver 18
Receives an angle adjustment signal for adjusting at least the tilt angles of the first slat 5a and the second slat 5b from an external operation terminal such as the remote controller 16.

Next, the control operation of the slats 5a and 5b provided in the vertical blind 1 according to the second embodiment will be described with reference to FIG. Here, the case where the width of the slats 5a and 5b is 100 mm and the pitch interval between the first slats 5a and the second slats 5b is 40 mm will be described.
Further, this control assumes a pattern in which the tilt angle of the angle adjustment signal of the slat 5a or the slat 5b is determined and input at the start of the operation by using the remote controller 16A shown in FIG. 7.

First, to adjust the tilt angles of the slats 5a and 5b, operate the remote controller 16A to select mode 1 (open mode), pull out the runner 4 along the hanger rails 3A and 3B, and then pull out the runner 4 along the hanger rails 3A and 3B. Are sequentially pulled out at predetermined intervals. Then, as shown in FIG. 9A, the runner 4 is pulled out to one end side of the hanger rails 3A and 3B, and the tilt operation is started in the fully opened state shown in step 1.

Then, when the mode is changed to the tilt mode, it is input to the control unit 15 via the receiving unit 18 that the target tilt angle of the slats 5a is in a fully closed state of 0 degrees. At this time, the determination unit 15f determines the tilt angle (90 degrees) of the current slats 5a and the tilt angle of the slats 5b (the tilt angle).
Based on (90 degrees), it is determined that if the slat 5a is fully closed as it is, an interferable region that may interfere with the slat 5b shown in the shaded area of step 2 in FIG. 9 (b) is generated. Therefore, the determination unit 15f rotates the slat 5b 20 degrees clockwise so as to remove the slat 5b from the coherent region shown in the shaded area first, as shown in step 3, before the slat 5a is fully closed. The tilt angle of the slat 5b is rotationally controlled from 90 degrees to 110 degrees to exclude the slat 5b from the coherent region. Next, as shown in step 4, the slats 5a are rotated counterclockwise to control the tilt angle from 90 degrees to 0 degrees. Then, the determination unit 1
5f determines whether or not there is an interferable region in the region (hatched portion) when the slats 5b are returned to the original tilt angle of 90 degrees in this state, and determines that the interferable region does not occur. Therefore, as shown in step 5, the slats 5b are tilted counterclockwise by 20 degrees to return to the original fully open state with a tilt angle of 90 degrees.

Next, when the mode is changed to the open mode, the target tilt angle of the slats 5a is 90.
It is input to the control unit 15 that the degree is fully open. At this time, when the determination unit 15f makes the slat 5a fully closed based on the current tilt angle (0 degree) of the slat 5a and the tilt angle (90 degrees) of the slat 5b, the diagonal line in step 6 of FIG. It is determined that an interferable region that may interfere with the slats 5b as shown in the section is generated. Therefore, the determination unit 15f rotates the slat 5b 20 degrees clockwise so as to remove the slat 5b from the interfering (shaded portion) region first, as shown in step 7, before the slat 5a is fully opened. The tilt angle of the slat 5b is rotationally controlled from 90 degrees to 110 degrees to exclude the slat 5b from the coherent area. Then, as shown in step 8, the slats 5a are rotated clockwise to control the tilt angle from 0 degrees to 90 degrees. Next, the determination unit 15f is in this state with the slats 5
It is also determined that b does not generate an interfering region in the shaded area when the original tilt angle is returned to 90 degrees. Therefore, as shown in step 9, the slats 5b are tilted 20 degrees counterclockwise to return to the original fully open state with a tilt angle of 90 degrees.

Next, an operation example when the switching remote controller 16A of the vertical blind 1 according to the second embodiment and the tilt operation of the slats 5a and 5b will be described with reference to FIGS. 10 and 11.

, 5b is paid out and ends.

Next, as shown in FIG. 10B, the switching button 160 of the remote controller 16A is pressed to select the tilt mode from the open mode. At this time, as shown in steps 11 to 13, the slats 5a are automatically controlled to be in the fully closed state and the slats 5b are controlled to be in the fully open state. Since this control is the same as the case shown in FIG. 9B, the description thereof will be omitted.

Then, from the state of step 14 shown in FIG. 10 (b), the slat rotation button 165 or 1
A case where 66 is pressed to bring the slat 5b into a fully closed state will be described. In this case, the determination unit 15f determines that there is no interference-possible region, and as shown in step 15, the slat 5b is rotated counterclockwise to tilt the tilt angle. From 90 degrees to 0 degrees, or slat 5 as shown in step 16.
Rotate b clockwise to change the tilt angle from 90 degrees to 180 degrees. At this time, the amount of lighting can be appropriately adjusted by setting the slats 5a, which is the lace fabric, to the fully closed state and adjusting the tilt angle of the slats 5b, which is the drape fabric. Finally, as shown in FIG. 11, when the switching button 160 of the remote controller 16A is pressed and the open mode is selected from the tilt mode, the slats 5a and 5b
Is automatically controlled from the fully closed state to the fully open state. At this time, the tilt angle of the slats 5b is first set to 1.
Return to 10 degrees to eliminate the coherent region (step 17), then return the tilt angle of the slat 5a to 90 degrees (step 18), and finally return the tilt angle of the slat 5b to 90 degrees (steps 19 to 20). ..

When one of the slats 5a or 5b is controlled, it is determined whether or not the slats 5a or 5b pass through the interferable region (S122).

Next, when it is determined by the determination unit 15f that it passes through the interferable region (Y in S122).

3). Then, the tilt angle control unit 15g rotates and controls the tilt angle of the slats 5a or 5b on the adjustment side of the angle adjustment signal based on the command from the determination unit 15f (S124). Next, the determination unit 15f determines whether or not the other slat 5a or 5b, which is not the adjustment target, passes through the interferable region when the rotation is controlled to the original position before rotation (S125). Then, the determination unit 1
When it is determined in 5f that the interference-possible region is not passed (No in S125), the tilt angle control unit 15g sets the other slat 5a or 5b that is not the adjustment side of the angle adjustment signal based on the command from the determination unit 15f. Rotation control is performed to the original position (S126). Further, when the determination unit 15f determines that the passage through the interferable region (Yes in S125), the rotation control of the other slat 5a or 5b that is not the adjustment side of the angle adjustment signal is not performed.

On the other hand, when the determination unit 15f determines that it does not pass through the interferable region (No in S122), the tilt angle control unit 15g is based on the command from the determination unit 15f, and the slats 5a or 5b to be adjusted for the angle adjustment signal. Is rotated and controlled based on the angle adjustment signal (S127).

(Modification example)
The vertical blind 1 according to the modified example of the second embodiment will be described with reference to FIGS. 13 and 14. In this modification, the remote controller 16C shown in FIG. 13 is used. When the OPEN button 181 is pressed on the remote controller 16C, the slats 5a and 5b are folded and stopped when they are completely opened. When the CLOSE button 182 is pressed, the slats 5a and 5b are extended and stopped when they are closed and the STOP button 183 is pressed. And the slats 5a and 5b stop at that position. Further, the slat rotation button 1 for controlling the rotation operation of the slat 5b on the indoor side
84,185, Slat rotation button 1 for controlling the rotation operation of the outdoor slat 5a
It has 86,187. Then, when the slat rotation buttons 184 and 186 are pressed, the slat 5a and 5b rotate clockwise only while the slat rotation buttons 184 and 186 are pressed, and the slat rotation buttons 185 and 18
When 7 is pressed, the tilt angle is adjusted by rotating the slats 5a and 5b in the counterclockwise direction only while the 7 is pressed.

Next, the slat control of the vertical blind 1 according to the present modification 1 will be described. When the angle adjustment signal of the first slats 5a is received from the remote controller 16C via the receiving unit 18 of the vertical blind 1, and it is determined that the determination unit 15f has an interference possible region, the tilt angle control unit 15g is rotationally controlled so as to remove the second slats 5b from the coherent region. The difference from the first embodiment is that in the present modification 1, it cannot be determined whether or not the remote controller 16C has an interferable region until immediately before the slats 5a and 5b come into contact with each other. This will be described with reference to FIG.

First, the tilt operation is started in the fully open state of step 21 of FIG. 14A, and in the shaded area where it is determined by the determination unit 15f that there is no interference-possible region, the slat rotation buttons 184 to 188 of the remote controller 16C are pressed.

The rotation is controlled immediately before the contact is made so as to remove the interference from the interfering area first. That is, the determination unit 15f of the vertical blind 1 of the present modification 1 determines whether or not the slats 5a and 5b are in contact with the remote controller 1.
Since the determination can be made only immediately after any of the slat rotation buttons 184 to 188 of 6C is pressed and a command is given, the slats 5a and 5b are gradually controlled so as to avoid the interference immediately before the slat 5a and 5b interfere with each other. Also in this configuration, similarly to the vertical blind 1 according to the second embodiment, it is possible to appropriately prevent the slats 5a and 5b from coming into contact with each other.

When the slat rotation button 196 is pressed, the slat 5i at the selected address is pressed only while it is pressed.
Alternatively, the tilt angle is adjusted by rotating 5j in the counterclockwise direction.

The remote controller 16E shown in FIG. 18B has the same operation method as the remote controller 16B shown in FIG. 7B. When the slats 5i and 5j are folded, the OPEN button 200 is pressed to reach the preset designated positions of the slats 5i and 5j. Moves. When the CLOSE button 201 is pressed to extend the slats 5i and 5j, the slats 5i and 5j reach a preset specified position.

As in the second embodiment, the remote controllers 16D and 16E are not limited to wireless communication, and may be provided with a function of communicating a command signal with the vertical blind 1, and are wired. It may be a switch-type external operation terminal that was used.

Next, the slat control of the vertical blind 1 performed by using the remote controller 16E will be described with reference to FIG. 19 (a) and 19 (b) show the case where the first slats 5i can rotate counterclockwise. In the case of step 30 of FIG. 19A, since the first slat 5i is not within the tilt range (inside the diagonal line) of the second slat 5j, the determination unit 15f determines that there is no interference-possible region, and the second slat 5j Is rotated to a predetermined angle. Step 3 of FIG. 19 (b)
In the case of 1, the first slat 5i is within the tilt range (inside the diagonal line) of the second slat 5j.
The determination unit 15f determines that there is an interference possible region. Therefore, as shown in step 32, the second slat 5j is first tilted counterclockwise outside the tilt range (diagonal line range) of the first slat 5i, and then the second slat 5j is tilted as shown in step 33. Tilt it counterclockwise to the desired angle. Then, since the second slat 5j is not within the tilt range (diagonal line range) of the first slat 5i, the first slat 5i is finally returned to the original position counterclockwise as shown in step 34.

On the other hand, FIGS. 19 (c) and 19 (d) show a case where the first slats 5i can rotate clockwise. In the case of step 35 of FIG. 19 (c), it is within the tilt range of the second slat 5j (
Since there is no first slat 5i (inside the diagonal line), the determination unit 15f determines that there is no interference-possible region, and rotates the second slat 5j to a predetermined angle. In the case of step 36 of FIG. 19D, the first slat 5i is within the tilt range (diagonal line) of the second slat 5j, and the determination unit 15f determines that there is an interference possible region. Therefore, as shown in step 37, the second slat 5 first.
The j is tilted clockwise outside the tilt range (diagonal line range) of the first slat 5i, and then the second slat 5j is tilted counterclockwise to a desired angle as shown in step 38. Then, when the second slat 5j is not within the tilt range (diagonal line range) of the first slat 5i, the first slat 5i is finally returned to the original position in the clockwise direction as shown in step 39.
