Description

[Technical field]

[0001] The present invention relates to an electric shading device in which the opening and closing of a shading material such as a curtain is controlled by a motor, and a control method thereof. [Background technology]

[0002] Curtains (shielding devices) whose opening and closing are controlled by a motor are widely used. In this case, each part of the curtain is attached to a corresponding runner, and each runner is movable along a rail (curtain rail). The opening and closing of the curtain is controlled by controlling the movement of the runner, particularly the end side of the curtain (the leading side when the curtain is closed), by a motor. In this case, the user can control the opening and closing of the curtain simply by operating a switch or a remote control transmitter near the curtain, greatly reducing the effort required by the user.

[0003] Generally, curtains are placed near windows, and opening and closing them controls the intake of sunlight into the room and the on / off of ventilation. When the curtains are open, sunlight and outside air are taken in, but the inside of the room is visible from the outside, and when the curtains are closed, the inside of the room is not visible from the outside, but sunlight cannot be taken in. To deal with such situations, double curtains are used, with one curtain on the window side and the other on the inside of the room. In this case, the curtain on the window side is a lace curtain, which can take in a certain amount of sunlight and has a certain degree of blocking ability against visibility from the outside, and the curtain on the inside of the room is a drape curtain made of a thick fabric that has a higher ability to block sunlight and block visibility from the outside than lace curtains.

[0004] By controlling the opening and closing of two types of curtains with different characteristics, various settings become possible, such as closing both types of curtains, opening both types of curtains, opening one curtain and closing the other curtain, etc. In this case, two curtain rails are formed in parallel for each curtain, and the opening and closing of each curtain is controlled independently.

[0005] Such a double curtain structure is described in Patent Documents 1 and 2. In the technology described in Patent Document 1, a single motor is connected to each of the two types of curtains via clutches, and by operating these clutches, the single motor controls the opening and closing of the two independent types of curtains.

[0006] Patent Document 2 describes a structure in which a motor is provided for each curtain (curtain rail), but a control unit and a power supply unit for controlling the motor are provided only on one side of the curtain rail. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Utility Model Application Publication No. 62-129984 [Patent Document 2] JP 2017-29371 A Summary of the Invention [Problem to be solved by the invention]

[0008] In the double curtain described above, the opening and closing operation of each curtain is controlled individually. However, when this double curtain is used in, for example, a hotel room, the user is often not an expert in this operation and is operating the double curtain for the first time. For such users, opening and closing such a double curtain is not easy. For this reason, a double curtain (electric shading device) that is extremely easy to open and close is desired.

[0009] The present invention has been made in consideration of the above problems, and an object of the present invention is to provide an invention that solves the above problems. [Means for solving the problem]

[0010] In order to solve the above problems, the present invention has the following configuration. The present invention provides an electric shading device in which the opening and closing operations of a first shielding material and a second shielding material, which are both controlled to open and close by an in-plane operation and which are installed approximately parallel to each other and spaced apart in a direction perpendicular to the in-plane direction, are controlled by a motor, and the electric shading device is characterized in that it includes an operation unit in which a first state in which the first shielding material and the second shielding material are both fully closed, a second state in which the first shielding material and the second shielding material are both fully open, and a third state in which the first shielding material is fully closed and the second shielding material is fully open are set, and which is provided with a first switch, a second switch, and a third switch corresponding to the first state, the second state, and the third state, respectively, and a control unit that, when any of the first to third switches is operated by the operation unit while the motor is stopped, drives the motor so as to realize any of the first to third states corresponding to any of the first to third switches that was operated. In the present invention, the control unit is configured to stop the motor when any of the first to third switches is operated on the operation unit while the motor is in operation. The present invention is characterized in that it comprises a first rail provided along the opening and closing direction of the first shielding material and a second rail provided along the opening and closing direction of the second shielding material, the opening and closing of the first shielding material being controlled by a position along the first rail of a first driving runner attached to the first shielding material, and the opening and closing of the second shielding material being controlled by a position along the second rail of a second driving runner attached to the second shielding material, the first rail and the second rail being fixed at one end side along the opening and closing direction, and comprising a base to which a first motor which is the motor that drives the first driving runner and a second motor which is the motor that drives the second driving runner are fixed. The present invention is characterized in that the control unit is provided on the base. In the present invention, the operation section and the control section are connected by a remote control. The present invention is characterized in that the first shielding material is a lace curtain, and the second shielding material is a drape curtain. The present invention is a control method for an electric shading device in which the opening and closing operations of a first shielding material and a second shielding material, which are both controlled to open and close by an in-plane operation and are installed approximately parallel to each other and spaced apart in a direction perpendicular to the in-plane direction, are controlled by a motor, and the control method is characterized in that a first state in which the first shielding material and the second shielding material are both fully closed, a second state in which the first shielding material and the second shielding material are both fully open, and a third state in which the first shielding material is fully closed and the second shielding material is fully open are set, an operation unit is provided in which a first switch, a second switch, and a third switch corresponding to the first state, the second state, and the third state, respectively, are provided, and when any of the first to third switches is operated while the motor is stopped, the motor is driven so as to realize any of the first to third states corresponding to any of the first to third switches that was operated. The present invention is characterized in that, when any of the first to third switches is operated while the motor is in operation, the motor is stopped. Effect of the Invention

[0011] Since the present invention is configured as described above, it is possible to obtain an electrically operated shading device that is extremely easy to open and close. [Brief description of the drawings]

[Figure 6] 1 is a perspective view showing a structure of an electric shading device according to an embodiment of the present invention; [Figure 7] 1 is a top view showing a structure and operation of an electric shading device according to an embodiment of the present invention; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] An electric shading device and a control method thereof according to an embodiment of the present invention will be described. Fig. 1 is a top view showing the operation of this electric shading device (double curtain) 1. Here, the top view shows that the upper side of the figure is the window side (outside) and the lower side of the figure is the room side (inside).

[0014] Here, outer curtains (lace curtains: first shielding material) 11, 12 made of thin translucent fabric are used on the left and right sides of the window (upper side in the figure). In FIG. 1, the upper side of the outer curtains 11, 12 is actually provided with a window of the room. The outer curtains 11, 12 are hung by being fixed by runners 51, 52 at six points in the figure at the upper part. Each runner 51, 52 is attached to a rail (first rail) 21 that extends horizontally above the outer curtains 11, 12 so as to be movable along the extension direction (horizontal direction) of the rail 21. In particular, the rightmost leading runner (first driving runner) 51A of the runners 51 and the leftmost leading runner (first driving runner) 52A of the runners 52 are driven by a motor as described later, and are controlled to move in opposite directions along the extension direction of the rail 21. As a result, the opening and closing of the outer curtains 11, 12 is controlled by the movement along the approximately in-plane direction. In FIG. 1, runners 51, 52 and rail 21 are shown simply with respect to their positional relationship (particularly in the horizontal direction), and the specific structure of rail 21 etc. will be described later.

[0015] Similarly, on the inside of the room (lower side in the figure), inner curtains (drape curtains: second shielding material) 31, 32 made of thick opaque fabric are used on the left and right sides, respectively, and runners 61, 62 (leading runners ((second driving runners)) 61A, 62A) and rails (second rails) 41 are provided for these. The opening and closing operations are also performed in the same way as for the outer curtains 11, 12. The rails (first rail) 21 and rails (second rails) 41 are approximately parallel to each other.

[0016] Here, the outer curtains (lace curtains) 11, 12 are made of a thin, semi-transparent fabric, so sunlight can pass through them and enter the room from the window. However, because there is a certain degree of visibility through them, if you do not want people to see inside the room from outside, simply covering the window with them is not enough.

[0017] On the other hand, the inner curtains (drape curtains) 31, 32 are made of a thick opaque fabric, so sunlight cannot enter the room from the window through them and visibility through them is low, so if you do not want the room to be seen from outside, simply covering the window with them is sufficient. Therefore, with this double curtain 1, by controlling the opening and closing of the inner curtains 11, 12 and the outer curtains 31, 32, respectively, the user can achieve the desired situation regarding the intake of sunlight into the room and the visibility from outside.

[0018] In Fig. 1, (a) shows the outer curtains 11, 12 and the inner curtains 31, 32 all fully closed, (b) shows a state where they are all halfway between open and closed (half open), and (c) shows a state where they are all fully open. Fig. 1(a) shows the state where sunlight capture and visibility from the outside are the lowest, and Fig. 1(c) shows the state where sunlight capture and visibility from the outside are the highest. Fig. 1(d) shows the state where the outer curtains 11, 12 are fully closed and the inner curtains 31, 32 are fully open. This state is applied, for example, when it is desired to let sufficient sunlight into the room from outside while reducing visibility from the outside.

[0019] During these operations, the movements of outer curtain 12 and inner curtain 32 are symmetrical to those of outer curtain 11 and inner curtain 31, respectively. Furthermore, the basic structure and movements of inner curtains 31, 32 are similar to those of outer curtains 11, 12. For example, when outer curtain 11 is in any of the above-mentioned states of fully open, half open, or fully closed, outer curtain 12 is also fully open, half open, or fully closed accordingly. The same is true for inner curtains 31, 32; when inner curtain 31 is in any of the states of fully open, half open, or fully closed, inner curtain 32 is also fully open, half open, or fully closed accordingly.

[0020] Fig. 2(a) is a perspective view of outer curtain 11 and the related structure in the state of Fig. 1(a), Fig. 2(b) is a perspective view of outer curtain 11 in the state of Fig. 1(b), and Fig. 2(c) is a perspective view of outer curtain 12 in the state of Fig. 1(c). As described above, the structure related to outer curtain 12 is symmetrical to that in the left and right, the structure related to inner curtain 31 is the same as that in Fig. 2, and the structure related to inner curtain 32 is the same as that in outer curtain 12. In Fig. 2 as well, the runner 51 and rail 21 are shown in a simplified manner with respect to only the positional relationship between them (particularly in the horizontal direction).

[0021] As shown in Figures 1 and 2, the opening and closing of each curtain is controlled by the movement of the leading runner. The two curtains in this double curtain 1 can be set to three basic states: (1) both the outer curtain and the inner curtain are fully closed (first state), (2) both the outer curtain and the inner curtain are fully open (second state), and (3) the outer curtain is fully closed and the inner curtain is fully open (third state). Here, (1) is the state in which the curtains block sunlight most strongly and also provide the lowest visibility from outside the room, while (2) is the state in which the maximum amount of sunlight is allowed into the room and also provides the highest visibility from outside the room. (3) is an intermediate state between (1) and (2), which allows a certain amount of sunlight to be taken in from the outside while also restricting visibility from the outside to a certain degree. However, depending on the timing of the switch operation, each curtain can also be set to an intermediate state between these two.

[0022] The following describes the configuration for controlling this double curtain 1. Fig. 3 shows the configuration related to the control of the outer curtains 11, 12 and the inner curtains 31, 32. As will be described later, the operation of the outer curtain 12 and the inner curtain 32 (leading runners 52A, 62A) is synchronized with the outer curtain 11 and the inner curtain 31 (leading runners 51A, 61A), respectively.

[0023] The leading runner (first driving runner) 51A that drives the outer curtain 11 and the leading runner (second driving runner) 61A that drives the inner curtain 31 are driven by a motor (first motor: outer motor) 71 and a motor (second motor: inner motor) 72, respectively. This structure will be described later. At this time, the movement of each leading runner is limited to a direction along each rail. The direction in which they move is controlled by the direction of rotation of each motor, and this makes it possible to control the opening and closing operations of the outer curtain 11 and the inner curtain 31. A control unit 80 provided with a CPU controls this operation, thereby controlling the opening and closing operations of each curtain. This control is performed by a user operating an operation unit 90 connected to the control unit 80. In addition, a power supply unit 100 is also provided for generating a power supply voltage for driving the control unit 80 and each motor from AC 100V.

[0024] Here, the operation unit 90 is provided with only three switches corresponding to the three states. Fig. 4(a) is a perspective view of the exterior of this operation unit 90. Here, there are provided a "close" button (first switch) 90A corresponding to the state (1), an "open" button (second switch) 90B corresponding to the state (2), and a "race" button (third switch) 90C corresponding to the state (3).

[0025] In addition, the leading runners 51A and 52A move to the right and left, respectively, to the state shown in FIG. 1(a), and the outer curtain 11 is in a fully closed state. At this time, the leading runner 51A abuts against the leading runner 52A that has moved in the opposite direction, and cannot move further to the right than this state. Therefore, for example, the motor 71 cannot rotate or the operating current becomes large, and the control unit 80 can recognize this (that the outer curtain 11 is fully closed). This allows the power supply to the motor 71 to be stopped in this state. In addition, when the leading runner 51A moves to the left and reaches the fully open state as shown in FIG. 1(c) and FIG. 2(c), the leftmost runner 51 in the figure abuts against the left stopper, causing the five runners 51 and the leading runner 51A to come into close contact with each other, and thus the leading runner 51A cannot move further to the left. Therefore, the control unit 80 can also recognize that the outer curtain 51 is fully open, and can stop the power supply to the motor 71. The same is true on the side of the inner curtain 31 (leading runners 61A, 62A). When the inner curtain 31 is fully closed or fully open, the control unit 80 can recognize this and stop the motor 72.

[0026] In this configuration, the above states (1) to (3) can be realized very easily by operating these three switches. In this case, if any of the switches is operated while the leading runners are moving (each motor is operating) to achieve the above states (1) to (3), the motor that is operating is stopped and the opening and closing operation of the corresponding curtain is set to stop at this point.

[0027] 5 is a flowchart showing this operation in the control unit 80. This operation is triggered by the operation of any button (switch) in the operation unit 90 (S1). The control unit 80 recognizes whether or not both motors 71, 72 are stopped at this point (whether or not at least one of the motors is operating) (S2). If no motor is operating (S2: No), it is determined which button (switch) has been operated.

[0028] When the "open" button 90B is operated (pressed) (S3: Yes), the control unit 80 operates the motors 71, 72 so that the outer curtain 11 and the inner curtain 31 are fully open (the state (2) above) (S4). Specifically, the control unit 80 controls the motors 71, 72 so that the leading runners 51A, 52A, 61A, and 62A are moved to the state shown in FIG. 1(c) (the outer curtain 11 and the inner curtain 31 are fully open). In this case, when the leading runners reach the position shown in FIG. 1(c) or are in the position shown in FIG. 1(c) at this point, the motors 71, 72 are stopped as described above. This ends the operation, and both the outer curtain 11 and the inner curtain 31 are fully open.

[0029] When the "close" button 90A is operated (pressed) (S5: Yes), the control unit 80 operates the motors 71, 72 so that the outer curtain 11 and the inner curtain 31 are fully closed (the state (1) above) (S6). Specifically, the control unit 80 controls the motors 71, 72 so that the leading runners 51A, 52A, 61A, and 62A are moved to the state shown in FIG. 1(a) (the outer curtain 11 and the inner curtain 31 are fully closed). In this case, when the leading runners reach the position shown in FIG. 1(a) or are in the position shown in FIG. 1(a) at this time, the motors 71, 72 are stopped. This ends the operation, and both the outer curtain 11 and the inner curtain 31 are fully closed.

[0030] When the "Race" button 90C is operated (pressed) (S7: Yes), the control unit 80 operates the motors 71 and 72 (S8) so that the outer curtain 11 is fully closed and the inner curtain 31 is fully open (the state (3) above). Specifically, the control unit 80 controls the motor 71 in the same manner as when the "Close" button 90A is operated (pressed) (S6) to move the leading runners 51A and 52A so that the outer curtain 11 is fully closed. On the other hand, the control unit 80 controls the motor 72 in the same manner as when the "Open" button 90B is operated (pressed) (S4) to move the leading runners 61A and 62A so that the inner curtain 31 is fully open. This ends the operation, and the outer curtain 11 is fully closed and the inner curtain 31 is fully open.

[0031] On the other hand, if any of the motors is operating (S2: Yes), it is recognized that one of the above operations (S4, S6, S8) is being performed at this time. In this case, the control unit 80 stops the motor that is operating (S9).

[0032] In the above operation, it is not necessary to individually control the opening and closing of outer curtain 11 and inner curtain 31, and the above states (1) to (3) can be achieved by operating only three types of switches. This makes this operation extremely easy, and for example, in a hotel room, a guest can easily perform this operation even without receiving instructions on how to use it.

[0033] As described above, for example, a state in which the outer curtain and the inner curtain are both half-open (the state in FIG. 1(b)) can be realized by operating any one of the switches (S2: Yes) during the movement from state (1) to state (2) (or vice versa). Similarly, a state in which the outer curtain is fully closed and the inner curtain is half-open can be realized by operating any one of the switches during the movement from state (3) to state (1), and a state in which the outer curtain is half-open and the inner curtain is fully open can be realized by operating any one of the switches during the movement from state (2) to state (3). In other words, the above three types of states can be easily realized by the above three types of switches, and by stopping the motor while it is operating (S9), states other than these three types can also be realized.

[0034] An example of a specific form of the configuration in FIG. 3 will be described. Here, a structure in which a first rail and a second rail are connected can be used. FIG. 6 shows a perspective view of a structure in which rails 21 and 41 in FIG. 1 are integrated. Also, in FIG. 6, the illustration of each curtain is omitted. FIG. 7 is a top view that typically shows the operation of each runner and the leading runner in this structure.

[0035] In FIG. 6, a rail (first rail) 21 and a rail (second rail) 41 are connected by a plate-shaped connecting part 200 in a direction perpendicular to the extension direction (opening / closing direction). In addition, on one side in the extension direction of the rail (the right side in FIG. 1 and FIG. 6), the rail 21 and the rail 41 are fixed via a box-shaped base 210. Motors 71 and 72 are provided inside the base 210, and these drive the leading runner as described above. In addition, the control unit 80 and the power supply unit 100 that supplies power to the control unit 80 and the motors 71 and 72 are also provided inside the base 210. The structure in FIG. 6 is fixed to the ceiling of a room or the like at multiple points in the connecting part 200 using fixing devices such as wood screws. The above-mentioned operation unit 90 is provided at a place away from the base 210 where the user can easily operate it, and is connected to the control unit 80 (base 210) by wiring. A power plug to which an AC 100V power supply is connected is connected to the power supply unit 100. Pulley 73 for driving leading runners 51A, 52A (not shown in FIG. 6) and pulley 74 for driving leading runners 61A, 62A are both provided on the upper side of base 210, and are driven by motors 71, 72, respectively.

[0036] In this structure, the rails 21, 41, base 210, etc. are integrated, so that the installation in the room is easy. After that, the user can easily install this motorized shading device by attaching each runner in Fig. 1 to the rails 21, 41 and attaching each curtain to them.

[0037] The cross-sectional shapes of rails 21 and 41 are set so that the runners attached thereto can move (slide) along the extension direction. In Fig. 7, outer curtains 11 and 12 are fully closed, and inner curtains 31 and 32 are fully open (the above-mentioned state (3)). Here, runners other than leading runners 51A, 52A, 61A, and 62A are not driven, and move freely with the opening and closing of each curtain accompanying the movement of the leading runner. In Figs. 1 and 7, only the upper part of each runner (the part inside each rail) is shown diagrammatically, and in Fig. 6, only the lower part of each runner (the part attached to each curtain below each rail) is shown.

[0038] 7, pulley 75 is rotatably provided on the opposite side of pulley 73 on rail 21, and pulley 76 is rotatably provided on the opposite side of pulley 74 on rail 41. A driving wire W1 is hung between pulley 73 and pulley 75 on the rail 21 side, and a driving wire W2 is hung between pulley 74 and pulley 76 on the rail 41 side. As motor 71 (pulley 73) rotates, the upper and lower parts of wire W1 move in opposite directions. Wire W2 is similarly driven by motor 72.

[0039] Therefore, by attaching a leading runner 51A to the lower portion of the wire W1 and attaching a leading runner 52A to the upper portion of the wire W1, the leading runner 51A and the leading runner 52A can be moved in the opposite directions in synchronization with the rotation of the motor 71. By similarly attaching a leading runner 61A and a leading runner 62A to the wire W2, they can be moved in the same manner.

[0040] 7, on the rail 21 side, the driving wire W1 is driven clockwise, so that the left leading runner 51A moves to the right and the right leading runner 52A moves to the left. As a result, the leading runners 51A and 52A come into contact with each other at their horizontal centers, restricting their movements and stopping the motor 71. As a result, the outer curtains 11 and 12 are fully closed.

[0041] Meanwhile, on the rail 41 side, the driving wire W2 is driven counterclockwise, so that the left leading runner 61A moves leftward and the right leading runner 62A moves rightward. As a result, the leading runner 61A is stopped by the left stopper via the five runners 61 and stops, and the leading runner 62A is stopped by the right stopper via the five runners 62 and stops. This causes the inner curtains 31, 32 to be fully open. This results in the above-mentioned state (3).

[0042] The control unit 80 recognizes the operation of the operation unit 90 and controls the motors 71, 72 provided in the base 210 together with the control unit 80 to perform the above-mentioned operation. In the configuration of FIG. 6, the control unit 80 and the operation unit 90 are connected by wires, but they may be connected by remote control communication using infrared rays, for example. In this case, the convenience of the operation unit for the user can be particularly improved. FIG. 4(b) is a top view showing the configuration of such a remote control transmitter (operation unit) 91. Since such a remote control transmitter 91 is used by being held by the user, it is preferable that it has an elongated shape that is easy to hold. In this case, the same operation as above can be performed by appropriately providing a receiving unit for this remote control communication in the base or other parts.

[0043] In the above example, lace curtains are used as the outer curtains (first shielding material) 11, 12 on the window side, and drape curtains are used as the inner curtains (second shielding material) 31, 32 on the room inside. However, drape curtains may be provided on the outside and lace curtains on the inside. In this case, the outer drape curtains are similar to the inner curtains (second shielding material) 31, 32, and the inner lace curtains are similar to the outer curtains 11, 12, and the third state is the drape curtains fully open and the lace curtains fully closed, allowing the same operation. In this case, too, it is possible to control the capture of sunlight and the visibility from the outside in the same way. Generally, drape curtains are more expensive than lace curtains, but in this case, the drape curtains are less noticeable to users inside the room (such as hotel guests), so for example, inexpensive drape curtains with high light blocking properties but low texture can be used. In this way, whether the first shielding material or the second shielding material is placed on the window side (or on the indoor side) (or the side that is fully closed (fully open) in the third state) can be set appropriately depending on the environment in which it is used, the type of curtain, etc.

[0044] In the above example, a lace curtain and a drape curtain are used in combination as shown in Fig. 1 as shielding materials that open and close horizontally. However, the above structure can also be used in a combination of shielding materials that open and close vertically (for example, a combination of Roman shades, or a combination of a Roman shade and a roll blind). In this case, while one first shielding material and one second shielding material are provided on each side in the above example, a configuration in which one first shielding material and one second shielding material are provided may be used, and the same operation is possible in this case as well.

[0045] In these cases, as the mechanism for opening and closing the above-mentioned mechanism using the runner, a mechanism used for electrically controlling the opening and closing of the above-mentioned mechanism can be appropriately used. Even in this case, the above-mentioned operation can be performed to make the operation extremely easy. The type of the first shielding material and the second shielding material can be selected based on the above-mentioned operation and purpose. [Explanation of symbols]
