Summary of the Invention

Problems to be Solved by the Invention

[0004] In the configuration disclosed in Patent Document 1, electrically operated components such as the lifting motor (30) are operated by supply of commercial power. Therefore, the wirings (60, 61) are normally drawn out from the back side of the head portion (11) so as not to be visible to the user. For this reason, the electric shading device as disclosed in Patent Document 1 includes a type in which the wirings (60, 61) are exposed to the outside on the left side of the head portion (11) and a type in which the wirings (60, 61) are exposed to the outside on the right side of the head portion (11).

[0005] Incidentally, development is currently underway on a battery-powered electric shielding device that uses power supplied from the battery to operate electrically operated parts such as the lifting motor (30). In such a battery-powered electric shielding device, it is being considered to place the battery in the head section. Furthermore, in the battery-powered electric shielding device, products that can be applied to areas with a relatively short width (length of the head section) are also being considered.

[0006] Under these circumstances, there is a risk that there may not be enough space to place various circuit boards in the head unit, and a reduction in the space required for circuit board placement is desired.

[0007] Furthermore, in battery-type electric shielding devices, it is preferable that the power supply state from the battery can be easily switched on and off, even when the power is off.

[0008] This invention was made in accordance with the above circumstances, and its purpose is to provide an electrically operated shielding device that can reduce the space required for placing a substrate. Furthermore, in the case of a battery-type electric shielding device, it is preferable to provide an electric shielding device that can easily switch the power supply state from the battery on and off, even when the power is off. [Means for solving the problem]

[0009] To solve the above problems, according to a first aspect of the present invention, an electric shielding device is provided, comprising a shielding material for blocking external light, a storage and deployment member for storing or deploying the shielding material, and a shielding drive mechanism equipped with a motor that provides driving force to drive the storage and deployment member, wherein the device comprises a rechargeable battery for supplying power to drive the motor, a first substrate on which a first electronic component is mounted, a second substrate on which a second electronic component is mounted, a substrate unit equipped with a substrate storage case for storing the first substrate and the second substrate, and a frame body housing the battery and the substrate unit, wherein the first electronic component is mounted on the first substrate so as to protrude toward the second substrate, the second electronic component is mounted on the second substrate so as to protrude toward the first substrate, the first substrate and the second substrate are superimposed in a stacked state, and in the superimposed arrangement, a non-interference arrangement is realized so that the first electronic component and the second electronic component do not interfere with each other.

[0010] Furthermore, in order to solve the above problems, according to a second aspect of the present invention, there is an electrically powered shielding device comprising a shielding material for blocking external light, a storage and deployment member for storing or deploying the shielding material, and a shielding drive mechanism equipped with a motor that provides a driving force for driving the storage and deployment member, wherein the device comprises a rechargeable battery for supplying power to drive the motor, a frame body housing a circuit board unit comprising the battery and a circuit board storage case, the circuit board unit comprising a cover member that covers the circuit board stored in the circuit board storage case, a push button that can be pressed on the surface of the cover member, the cover member being exposed on the opening surface of the frame body, and a charging port being exposed on the frame body to which an external charging cord can be connected, the power supply can be switched on by pressing the push button when the power is off, and the power supply can be switched on by energizing the charging port when the power is off. [Effects of the Invention]

[0011] According to the present invention, it is possible to provide an electrically operated shielding device that can reduce the space required for placing the substrate. Furthermore, in the present invention, it is preferable to provide an electric shielding device of the battery type that can easily switch the power supply state from the battery on and off, even when the power is off.

[Mode for Carrying Out the Invention]

[0013] Hereinafter, a roll screen 10 as an electrically operated shielding device according to an embodiment of the present invention will be described based on the drawings. In the following description, the direction connecting the indoor side and the outdoor side of the roll screen 10 is defined as the front-rear direction, the front side in the front-rear direction is the indoor side, and the rear side in the front-rear direction is the outdoor side.

[0014] (1. Configuration of Roll Screen 10) FIG. 1 is a perspective view showing the overall configuration of the roll screen 10 according to the present embodiment, in a state where a part of a shield 60 is omitted. FIG. 2 is a cross-sectional view of the roll screen 10 shown in FIG. 1, and is a view showing a state of being cut along the longitudinal direction of an upper frame portion 20.

[0015] The roll screen 10 is mainly used for window frames and partitions, and in particular, the roll screen 10 in the present embodiment is of a type supplied with power by a battery 40. For this reason, it can be easily installed even in a place where there is no nearby power outlet, so it can be installed outdoors and in various other places compared with the conventional type that is supplied with power from a power outlet.

[0016] As shown in FIG. 1 and FIG. 2, the roll screen 10 includes an upper frame portion 20, a winding mechanism 50, a shield 60, a screen 70, and a weight bar portion 80 as main constituent elements. The upper frame portion 20 further includes a frame body 21, a substrate unit 30, and a battery 40.

[0017] (1-1. Regarding frame 21) Figure 3 is a perspective view showing the upper frame portion 20. Figure 4 is a cross-sectional view showing the long frame 22 of the upper frame portion 20 cut near the substrate unit 30.

[0018] The frame body 21 includes a long frame 22, an upper bracket 23, and a pair of side bracket sets 24. The long frame 22 is a long-shaped member (an example of a molded material), and its cross-section is provided in the shape of a frame with an open top. For this reason, the long frame 22 is provided with an inner frame portion 22a in which a circuit board unit 30 and a battery 40 can be placed. The inner frame portion 22a is provided with a circuit board placement portion 25 and a battery placement portion 26, which will be described later.

[0019] The upper bracket 23 is a component that holds the elongated frame 22 and is fixed to a ceiling (not shown) or a ceiling-side frame attached to the ceiling, for example, via screws. The upper bracket 23 has hook portions 23a on both ends in the front-rear direction, and these hook portions 23a engage with flange portions 22b located on the upper side of the elongated frame 22. As a result, the upper bracket 23 holds the elongated frame 22, and the elongated frame 22 is fixed to the ceiling side via the upper bracket 23.

[0020] The pair of side bracket assemblies 24 are fixed to both ends of the elongated frame 22 and protrude downward from the elongated frame 22. The pair of side bracket assemblies 24 rotatably support the rotating support member 51 for pivotally supporting the winding cylinder 55 of the winding mechanism 50 on the lower side of the elongated frame 22.

[0021] The pair of side bracket sets 24 have different configurations on the left and right sides. In the following description, the side bracket set 24 located on the left side when the roller screen 10 is viewed from the front will be referred to as side bracket set 24L, and the side bracket set 24 located on the right side will be referred to as side bracket set 24R. Side bracket set 24L corresponds to one side bracket set 24L, and side bracket set 24R corresponds to the other side bracket set 24R.

[0022] Figure 5 is a perspective view showing the configuration of the side bracket assembly 24L. Figure 6 is a perspective view showing the configuration of the side bracket assembly 24R. In addition to the side bracket assemblies 24L and 24R, the rotating support member 51 is also shown in Figures 5 and 6. As shown in Figure 5, the side bracket assembly 24L includes a side frame 241, an outer cover 242, an end locking member 243, and a power supply bracket 244.

[0023] The side frame 241 is provided in a flat plate shape, and its appearance is such that its width gradually decreases from the top to the bottom, and its lower side is provided in an arc shape. This side frame 241 is a member for fixing the end of the long frame 22 and the power supply bracket 244 via screws, and has holes for inserting screws.

[0024] Furthermore, the outer cover 242 is a cover that hides screw holes and other parts of the side frame 241, and is attached to the side frame 241 by snapping or similar means.

[0025] The end locking member 243 is a member that locks onto the end of the long frame 22 at the upper part of the side frame 241. This end locking member 243 prevents the upper bracket 23, which is movable along the long frame 22, and the members positioned in the inner frame portion 22a from falling off the end of the long frame 22, and also prevents other members from entering the inner frame portion 22a from the end of the long frame 22.

[0026] The power supply bracket 244 has a cylindrical portion 244a, a sleeve portion 244b, and a shaft mounting portion 244c. The cylindrical portion 244a is a thin cylindrical part, and connection terminals (not shown) and wiring connected to these connection terminals are provided in its inner cylindrical portion.

[0027] Furthermore, the sleeve portion 244b is a frame-shaped portion that protrudes upward from the cylindrical portion 244a, and its inner frame portion is in communication with the inner cylinder portion of the cylindrical portion 244a. Therefore, the wiring arranged in the inner cylinder portion of the cylindrical portion 244a is guided through the inner frame portion of the sleeve portion 244b to the inner frame portion 22a of the long frame 22.

[0028] The shaft mounting portion 244c is a cylindrical part that protrudes in the axial direction of the winding cylinder 55. The rotating support member 51 is supported on the outer circumference of this shaft mounting portion 244c in a rotatable manner. The shaft mounting portion 244c also has a fitting hole 244c1 that is recessed from its protruding end. A fitting shaft of the winding cylinder 55 (not shown), which will be described later, is inserted into the fitting hole 244c1.

[0029] Furthermore, a charging port 244d is provided on the lower side of the cylindrical portion 244a of the power supply bracket 244. This charging port 244d is a hole-shaped portion into which an external charging cord 90 is inserted, and the cord insertion part of the connection terminal is located inside it.

[0030] Next, the side bracket assembly 24R will be described. As shown in Figure 6, the side bracket assembly 24R is provided with the same side frame 241, exterior cover 242, and end locking member 243 as the side bracket assembly 24L. Therefore, the description of the side frame 241, exterior cover 242, and end locking member 243 in the side bracket assembly 24R will be omitted. However, as shown in Figure 6, the side bracket assembly 24R is not provided with a power supply bracket 244. On the other hand, unlike the side bracket assembly 24L, the side bracket assembly 24R is provided with a case support member 245.

[0031] The case support member 245 has a housing portion 245a and an engaging cylinder portion 245b. The housing portion 245a is a part that can house wiring and circuit boards that supply power to drive the motor 53, which will be described later. The engaging cylinder portion 245b is provided in a form in which a cylindrical shape is divided into multiple sections by slits, and engaging claws are arranged in these slits. This engaging cylinder portion 245b engages with the end side of the motor case 52, which will be described later, thereby supporting the motor case 52 in a non-rotatable state.

[0032] As is clear from Figure 5, the power supply bracket 244 is provided in a shape that is symmetrical in the front-rear direction. Therefore, the power supply bracket 244 can be placed not only on the side bracket assembly 24L side, but also on the side bracket assembly 24R side.

[0033] Therefore, in the type where the charging port 244d is located on the left side when viewed from the front, the power supply bracket 244 is provided on the side bracket assembly 24L. In this case, the side bracket assembly 24R is provided with a case support member 245 as shown in Figure 6.

[0034] On the other hand, in the type where the charging port 244d is located on the right side when viewed from the front, the power supply bracket 244 is provided on the side bracket assembly 24R. In this case, the case support member 245 is provided on the side bracket assembly 24L. In other words, it is easy to switch between the power supply bracket 244 and the case support member 245.

[0035] Here, regardless of whether the power supply bracket 244 is positioned on the side bracket assembly 24L or 24R, the charging port 244d is located within the replacement charging range R1, which allows for easy charging by connecting the external charging cord 90. In the configuration shown in Figure 5, the replacement charging range R1 is on the underside of the power supply bracket 244 (cylindrical portion 244a), but if the external charging cord 90 can be easily inserted into the charging port 244d, a position slightly offset from the underside is also included in the replacement charging range R1.

[0036] Therefore, on either the left or right side of the roller screen 10, the same power supply bracket 244 can be swapped, and the charging cord 90 can be easily connected from the charging port 244d located in the replacement charging range R1.

[0037] Furthermore, the inner frame portion 22a of the long frame 22 is provided with a substrate placement portion 25 for arranging the substrate unit 30. The substrate placement portion 25 is provided with unillustrated protrusions for positioning the substrate unit 30.

[0038] Furthermore, the inner frame portion 22a is also provided with a battery placement portion 26. The battery placement portion 26 may be positioned adjacent to the circuit board placement portion 25 in order to shorten the wiring between it and the circuit board placement portion 25, or it may be positioned with a predetermined distance between it and the circuit board placement portion 25.

[0039] (1-2. Regarding the second configuration example of the power supply bracket 244) In the configuration described above, the power supply bracket 244 has a charging port 244d on its lower side. However, the charging port is not limited to being located on the lower side of the power supply bracket 244. For example, as shown in Figure 7, a configuration may be adopted in which charging ports 244e are provided on both the front (indoor side) and rear (outdoor side) of the power supply bracket 244.

[0040] Even with this configuration, it is possible to have a charging port 244e on either the left or right side of the roll screen 10 using the same power supply bracket 244 component. That is, in the configuration shown in Figure 1, where the power supply bracket 244 is provided on the left side bracket assembly 24L when viewed from the front, charging can be done mainly by plugging the external charging cord 90 into the left charging port 244e in Figure 7. Also, in the configuration where the power supply bracket 244 is provided on the right side bracket assembly 24R when viewed from the front, charging can be done mainly by plugging the external charging cord 90 into the right charging port 244e in Figure 7.

[0041] In other words, in the configuration shown in Figure 7, the replacement charging range R1 is provided as a pair: the front side, which is the indoor side of the power supply bracket 244 (cylindrical portion 244a), and the rear side, which is opposite to the indoor side.

[0042] In the configuration shown in Figure 7, the charging port 244e faces downwards on both the front (indoor side) and rear (outdoor side). This prevents interference between the shield 60 and the charging cord 90, especially on the front (indoor side).

[0043] (1-3. Regarding the circuit board unit 30 and battery 40) Next, the substrate unit 30 will be described. As shown in Figures 3 and 4, the inner frame portion 22a is provided with a substrate placement portion 25, and the substrate unit 30 is placed in this substrate placement portion 25. Figure 8 is a cross-sectional view showing the configuration of the substrate unit 30, and shows the state when the substrate unit 30 (upper frame portion 20) is cut along the longitudinal direction. As shown in Figures 3, 4 and 8, in this embodiment, the substrate unit 30 has a substrate storage case 31, a top plate 32, a voltage conversion board 33, and a charging control board 34.

[0044] The circuit board housing case 31 is a case that houses the voltage conversion board 33 and the charge control board 34 in predetermined positions inside it. Specifically, the circuit board housing case 31 is provided with a lower locking portion 31a and an upper locking portion 31b inside it, with the voltage conversion board 33 being locked to the lower locking portion 31a and the charge control board 34 being locked to the upper locking portion 31b above it. However, a configuration in which the charge control board 34 is locked to the lower locking portion 31a and the voltage conversion board 33 is locked to the upper locking portion 31b may also be adopted.

[0045] Furthermore, in the configuration shown in Figure 3, the longitudinal end of the circuit board housing case 31 is open. Therefore, wiring electrically connected to the voltage conversion board 33, the charge control board 34, and the battery 40 can enter the interior of the circuit board housing case 31 through this opening.

[0046] Furthermore, the top plate 32 is a plate-shaped member that covers the voltage conversion board 33 and the charging control board 34 by closing the opening on the top side of the circuit board housing case 31, and is exposed on the opening surface of the frame body 21 to accommodate multiple components. As shown in Figure 8, the top plate 32 is provided with a recessed portion 32a that is recessed downwards from its surroundings. Below this recessed portion 32a is an insertion hole 32b, through which the release button 34b, which will be described later, is inserted.

[0047] Furthermore, the voltage conversion board 33 is a board on which electronic components are mounted for converting power of a predetermined voltage supplied from the battery 40 to a predetermined voltage for operating the motor 53 and other electrical parts. The charge control board 34 is a board for controlling the charging state of the battery 40 and controlling the power output from the battery 40 to sleep mode, etc. Note that the voltage conversion board 33 corresponds to the first board and board, and the charge control board 34 corresponds to the second board and board.

[0048] Here, as shown in Figure 8, the protrusions 33a of electronic components mounted on the voltage conversion board 33 are arranged so as not to interfere with the protrusions 34a of electronic components mounted on the charge control board 34. In the configuration shown in Figure 8, protrusions 34a are provided on both ends of the charge control board 34, and these protrusions 34a are located outside the protrusions 33a mounted on the voltage conversion board 33.

[0049] Specifically, as shown in Figures 4 and 8, the voltage conversion board 33 and the charge control board 34 are superimposed in a stacked configuration. However, in this superimposed configuration, the protrusions 33a of the voltage conversion board 33 and 34a of the charge control board 34 are arranged in an alternating, non-interfering configuration. This makes it possible to reduce the vertical height of the board unit 30. The protrusions 33a correspond to the first electronic component, and the protrusions 34a correspond to the second electronic component.

[0050] As is clear from Figures 4 and 8, the sum of the first dimension H1, which is the height dimension of the protrusion 33a from the voltage conversion board 33, and the second dimension H2, which is the height dimension of the protrusion 34a from the charge control board 34, is set to be greater than the inter-board distance H3, which is the height distance between the voltage conversion board 33 and the charge control board 34. Therefore, the height dimension of the board unit 30 can be reduced.

[0051] In addition to the protrusion 34a mentioned above, the charging control board 34 also has a release button 34b that corresponds to the push button. The release button 34b is a button that allows the power supply to be switched on when the push button is pressed while the roll screen 10 is in sleep mode with the power off. The upper part of this 34b protrudes from the insertion hole 32b, allowing the user to press it. However, it is preferable that the upper end of the release button 34b does not protrude above the upper surface of the top plate 32. In the sleep mode with the power off of the roll screen 10, the power supply can be switched on by supplying power to the charging port 244d.

[0052] Furthermore, the battery 40 is a secondary battery that stores the power supplied to the power consumption section of the roll screen 10. As described above, this battery 40 is located in the battery placement section 26 of the inner frame section 22a. In the configuration shown in Figure 3, a locking device 41 is attached to the battery placement section 26, and the battery 40 is attached to the battery placement section 26 via this locking device 41.

[0053] (1-4. Regarding the winding mechanism 50) Next, the winding mechanism 50 will be described. The winding mechanism 50 is a mechanism for operating the opening and closing of the screen 70, which will be described later, and corresponds to the shielding drive mechanism. This winding mechanism 50 is provided between the pair of side bracket sets 24 described above and comprises a rotating support member 51, a motor case 52, a motor 53, an adapter 54, and a winding cylinder 55.

[0054] The rotating support member 51 is a member that is rotatably supported on the outer circumference of the engaging cylinder portion 245b of the case support member 245 of the side bracket assembly 24R described above. This rotating support member 51 is provided with an inner cylinder support portion 51a and a guide cylinder portion 51b. The inner cylinder support portion 51a is the part that is inserted into the inner cylinder side at one end of the winding cylinder 55 and is a member that supports one end of the winding cylinder 55. In the configuration shown in Figure 6, a total of six inner cylinder support portions 51a are provided, but the number can be changed as appropriate. The guide cylinder portion 51b is a cylindrical portion into which the tip guide portion 52a of the motor case 52 can be inserted.

[0055] Furthermore, the motor case 52 is a non-rotatable member positioned on the inner diameter side of the rotation support member 51. As shown in Figure 2, the motor case 52 is provided with a tip guide portion 52a and a housing case portion 52b. The tip guide portion 52a is the part inserted into the inner cylinder side of the guide cylindrical portion 51b, and a guide hole 52a1 that penetrates in the axial direction is provided on the radial center side of the tip guide portion 52a, through which wiring connected to the motor 53 is arranged. The housing case portion 52b is the case portion that houses the motor 53.

[0056] The motor 53 is fixed inside the housing case 52b in a non-rotatable state. The motor shaft (not shown) of the motor 53 is rotated by the supply of power to the motor 53.

[0057] An adapter 54 is attached to the motor shaft. The outer circumference of the adapter 54 is in contact with the inner surface of the winding cylinder 55. Therefore, when the motor 53 is driven, the winding cylinder 55 and the rotating support member 51 rotate together via the adapter 54.

[0058] Furthermore, a rotating support member 51 is also provided in the side bracket assembly 24L. On the side bracket assembly 24L side, the rotating support member 51 is rotatably supported on the outer circumference of the shaft mounting portion 244c of the power supply bracket 244. However, the motor case 52 and motor 53 are not located on the side bracket assembly 24L side.

[0059] Furthermore, the winding tube 55 is a cylindrical, elongated member used to wind up or unwind the screen 70, which will be described later, and corresponds to the storage and deployment member. In order to enable the winding up of the screen 70 in this way, one end (upper end) of the screen 70 is fixed to the winding tube 55.

[0060] (1-5. Regarding Shield 60) Next, the shield 60 will be described. The shield 60 is attached to the front (indoor side) of the long frame 22. This shield 60 is a component that blocks light leaking from between the frame body 21 and the winding cylinder 55, and has a length and height sufficient for that light blocking. In the configuration shown in Figure 1, a portion of the left side of the shield 60 is omitted, but from the viewpoint of light blocking, the shield 60 is attached along the entire length of the long frame 22.

[0061] (1-6. Regarding Screen 70) Next, the screen 70 will be described. The screen 70 is a rectangular piece of fabric used to block out external light entering the room from windows, etc., and corresponds to a shading material. The screen 70 is wound around the winding cylinder 55 of the winding mechanism 50. A weight bar 80 is attached to the lower end of the screen 70 to prevent external light from entering from the lower end due to the screen 70 curling up.

[0062] (1-7. Regarding the weight bar section 80) Next, the weight bar section 80 will be described. As shown in Figure 1, the weight bar section 80 is provided at the lower end of the screen 70. In other words, by attaching the weight bar section 80 to the lower end of the screen 70, tension is applied so that the screen 70 does not sag even when the screen 70 is pulled out (rewound).

[0063] (2. Regarding the function of roller screen 10) In the roll screen 10 configured as described above, the motor 53 can be driven by power supplied from the battery 40. By driving the motor 53, the winding cylinder 55 can be rotated to unfold and retract the screen 70.

[0064] Here, the power supply bracket 244 can be attached to either one of the pair of side bracket sets 24, 24L or 24R, and in either mounting configuration, the charging port 244d has a replaceable charging range R1, so the user can easily plug an external charging cord 90 into the charging port 244d.

[0065] Furthermore, the battery 40 can be charged by plugging an external charging cord 90, as shown in Figure 1, into the charging port 244d. Also, if a certain period of time has passed during which the motor 53 or other drive parts are not operating, the battery 40 will enter a sleep mode that reduces power consumption. In this case, the sleep mode can be easily exited by pressing the release button 34b.

[0066] Furthermore, since the release button 34b is located in the recessed area 32a, it is possible to prevent the user from accidentally pressing the release button 34b. Therefore, it is possible to prevent the sleep mode from being accidentally released during tasks such as installing the roller screen 10.

[0067] (3. Regarding variations) Although one embodiment of the present invention has been described above, the present invention can be modified in various ways without changing its essence.

[0068] The electric shielding device of the present invention is not limited to a roller screen 10, but can also be applied to a vertical blind, for example. Such configurations are shown in Figures 9 and 10. Figure 9 is a perspective view showing the configuration of a vertical blind 100 according to a modified example of the present invention, and is a view from the front. Figure 10 is a perspective view showing the vertical blind 100 shown in Figure 9, viewed from the rear.

[0069] This vertical blind 100 is equipped with a hanger rail 20A that corresponds to the upper frame portion 20 described above. Specifically, the hanger rail 20A that corresponds to the upper frame portion 20 has a frame body 21A that corresponds to the frame body 21, a circuit board unit 30A that corresponds to the circuit board unit 30, and a battery 40A that corresponds to the battery 40.

[0070] In the configurations shown in Figures 9 and 10, the hanger rail 20A differs from the upper frame portion 20 in the roll screen 10 described above in that the circuit board unit 30A and battery 40A are exposed on the rear side. However, the hanger rail 20A may also be configured in the same way as the upper frame portion 20, with the circuit board unit 30A and battery 40A exposed on the upper side.

[0071] The frame body 21 includes a long frame 22A corresponding to the long frame 22, an upper bracket 23A corresponding to the upper bracket 23, and a pair of side bracket sets 24A corresponding to the pair of side bracket sets 24.

[0072] Furthermore, the vertical blind 100 is equipped with a slat drive mechanism 110 and a plurality of slats 120. In other words, since the vertical blind 100 is equipped with a plurality of slats 120 as a shielding material instead of a screen 70, it is equipped with a slat drive mechanism 110 that corresponds to the shielding drive mechanism, unlike the winding mechanism 50 of the roller screen 10.

[0073] The slat drive mechanism 110 includes a tilt shaft and tilt motor (not shown), a drive shaft and drive motor (not shown), and a runner 111, etc. The runner 111 is a member that can move along the hanger rail 20A. The runner 111 is provided with a first insertion hole (not shown) and a second insertion hole (not shown) arranged in the front-to-back direction. The first insertion hole is for inserting the tilt shaft, and the second insertion hole is for inserting the drive shaft.

[0074] Furthermore, the runner 111 has a suspension shaft 112. The suspension shaft 112 is a member that rotates with the vertical direction as its axis, and rotates in conjunction with the rotation of the tilt axis.

[0075] The tilt axis is a shaft-shaped member that is rotated by the drive of a tilt motor. The rotation of the tilt axis rotates the suspension shaft 112 of the runner 111, causing the slat 120 suspended from the suspension shaft 112 to rotate, thereby allowing for adjustment of daylighting.

[0076] Furthermore, a helical groove is formed on the drive shaft. A projection of the lead runner 111a, located at the end (front side) of the runner 111, fits into this helical groove. Therefore, when the drive shaft rotates due to the drive motor's drive, the lead runner 111a moves along the drive shaft to one side or the other side by a screw action, depending on the direction of rotation.

[0077] As this movement occurs, the runners 111, which are lined up along the longitudinal direction of the hanger rail 20A, are sequentially pulled out or, conversely, pushed back. As a result, the slats 120, which are suspended from the suspension shafts 112 of the runners 111, are sequentially pulled out to one side along the hanger rail 20A, or, conversely, sequentially folded towards the other end of the hanger rail 20A.

[0078] Furthermore, the slat 120 is a light-blocking material whose length is in the vertical direction. This slat 120 is made of thin wooden boards with light-blocking properties or a fabric with similar light-blocking properties, but it may also be made of a semi-transparent lace fabric.

[0079] Here, as shown in Figures 9 and 10, the hanger rail 20A is provided with a case cover 244A corresponding to the power supply bracket 244, and this case cover 244A is provided with a charging port 244Ad into which an external charging cord 90 can be inserted. In the configuration shown in Figures 9 and 10, the charging ports 244Ad are provided on the front and rear sides of the case cover 244A, respectively.

[0080] Therefore, it is possible to have a charging port 244Ad on either the left or right side of the vertical blind 100 using the same case cover 244A component.

[0081] In the configurations shown in Figures 9 and 10, the charging ports 244Ad are provided on the front and rear sides of the case cover 244A, respectively. However, the charging ports may also be provided on the bottom side of the case cover 244A.

[0082] Furthermore, a gear mechanism (not shown) for transmitting the driving force from the tilt motor to the tilt axis may be housed inside the case cover 244A. In other words, the case cover 244A may function as a gear case for housing the gear mechanism. In this case, the charging control board 34 described above may be placed in the part of the case cover 244A where the gear mechanism is not located (space for the circuit board).

[0083] Thus, when arranging the gear mechanism inside the case cover 244A, a configuration may be adopted in which one side bracket set 24A and the other side bracket set 24A cannot be swapped. In that case, instead of the charging control board 34, an infrared receiving board capable of receiving infrared light from an external remote controller may be placed in the above-mentioned space for the circuit board. When the infrared receiving board is placed inside the case cover 244A, the case cover 244A may be configured to have a charging port 244Ad, or it may be configured not to have a charging port 244Ad. An example of such a configuration is shown in Figure 11. In the configuration shown in Figure 11, the case cover 244A can be fitted with either a charging attachment / detachment part 244A1, which is provided with a charging port 244Ad, or a receiving attachment / detachment part 244A2, which is capable of receiving infrared light.

[0084] Furthermore, in the configuration shown in Figure 11, the case cover 244A has round holes (not shown in numerals) at its four corners, and screws are inserted through these holes and screwed into the long frame 22A. One of these holes is provided in both the charging attachment / detachment section 244A1 and the light receiving attachment / detachment section 244A2. Therefore, by removing the screw from either the charging attachment / detachment section 244A1 or the light receiving attachment / detachment section 244A2, it is possible to swap the two. The charging attachment / detachment section 244A1 and the light receiving attachment / detachment section 244A2 correspond to attachment / detachment sections. The light receiving attachment / detachment section 244A2 corresponds to the operation attachment / detachment section that receives external operation signals. The operation attachment / detachment section may also be operated by signals other than infrared.

[0085] Furthermore, the roller screen 10 and vertical blind 100 described above are equipped with a battery 40, and the motor 53 and other components are driven by the battery's charge. However, the roller screen 10 and vertical blind 100 may also be of a dual-purpose type that can be supplied not only by power from the battery 40 but also by commercial power from an outlet via a power cord.

[0086] In this type of dual-use system, which uses both battery 40 and power outlets, the upper bracket 23 must be attached to the ceiling or wall while the roller screen 10 is being held up by hand. As this occupies both hands, it is preferable to hang the roller screen 10 from the upper bracket 23 using the suspension cord 200, as shown in Figures 12 and 13.

[0087] Figure 12 is a perspective view showing a roll screen 10 of the type in which the upper bracket 23 is attached to the upper side of the wall, suspended from the upper bracket 23 by a suspension cord 200. Figure 13 is a perspective view showing a roll screen 10 of the type in which the upper bracket 23 is attached to the ceiling, suspended from the upper bracket 23 by a suspension cord 200. In Figures 12 and 13, a power cord 210 is also shown in addition to the suspension cord 200.

[0088] However, if the width of the suspension cord 200 is too narrow, there is a risk of damaging the fabric of the screen 70. Therefore, the suspension cord 200 is not a string, but rather a tape-like material with a width sufficient not to damage the screen 70.

[0089] This aims to achieve both improved ease of installation for the roller screen 10 and protection against damage to the screen 70.

[0090] (4. Note) The contents described in the above-mentioned embodiment can be understood as follows, for example, and can produce the following effects. [1] That is, An electric shading device for a roller screen 10 and a vertical blind 100, comprising a light-blocking material (screen 70, slats 120) for blocking external light, a storage and deployment member (winding cylinder, drive shaft) for storing or deploying the light-blocking material (screen 70, slats 120), and a shading drive mechanism (winding mechanism 50, slat drive mechanism 110) equipped with a motor 53 that provides driving force to drive the storage and deployment member (winding cylinder, drive shaft), A rechargeable battery 40,40A that supplies power to drive the motor 53, A circuit board unit 30 comprising a first circuit board (voltage conversion board 33) on which a first electronic component (protrusion 33a) is mounted, a second circuit board (charge control board 34) on which a second electronic component (protrusion 34a) is mounted, and a circuit board housing case 31 that houses the first circuit board (voltage conversion board 33) and the second circuit board (charge control board 34), A frame body 21 housing the battery 40 and the circuit board unit 30, Equipped with, The first electronic component (protrusion 33a) is mounted on the first substrate (voltage conversion substrate 33) so as to protrude towards the second substrate (charge control substrate 34). The second electronic component (protrusion 34a) is mounted on the second substrate (charge control substrate 34) so ​​as to protrude towards the first substrate (voltage conversion substrate 33). The first substrate (voltage conversion substrate 33) and the first substrate (voltage conversion substrate 33) are arranged in a superimposed position so that they are stacked on top of each other. In the superimposed arrangement, a non-interference arrangement is achieved so that the first electronic component (protrusion 33a) and the second electronic component (protrusion 34a) do not interfere with each other.

[0091] Therefore, the first substrate (voltage conversion substrate 33) and the second substrate (charge control substrate 34) are not arranged adjacent to each other in the longitudinal direction of the frame body 21, but rather overlap each other. This makes it possible to reduce the longitudinal space occupied by the substrate unit 30 in the longitudinal direction of the frame body 21. In other words, it becomes possible to reduce the space occupied by the first substrate (voltage conversion substrate 33) and the second substrate (charge control substrate 34) in the inner frame portion 22a of the long frame 22.

[0092] [2] In addition, in the above embodiment, in the contents of [1] above, When the direction connecting the first substrate (voltage conversion substrate 33) and the second substrate (charge control substrate 34) is defined as the height direction, In a non-interfering configuration, Preferably, the sum of the first dimension H1, which is the height dimension of the first electronic component (protrusion 33a) from the first substrate (voltage conversion substrate 33), and the second dimension H2, which is the height dimension of the second electronic component (protrusion 34a) from the second substrate (charge control substrate 34), is greater than the inter-substrate distance H3, which is the height distance between the first substrate (voltage conversion substrate 33) and the second substrate (charge control substrate 34).

[0093] In this configuration, the height dimension of the substrate unit 30 can be reduced.

[0094] [3] In addition, the above embodiments include, in addition to the contents described in either [1] or [2] above, or a combination thereof, The circuit board housing case 31 has a top plate 32 attached to it that covers the first circuit board (voltage conversion board 33) and the second circuit board (charge control board 34) housed in the circuit board housing case 31. A recess 32a is provided on the upper surface of the top plate 32, and a push button (release button 34b) attached to the second circuit board (charging control board 34) protrudes from the recess 32a via a through hole 32b. Preferably, the tip of the protrusion of the push button (release button 34b) does not protrude beyond the upper surface of the top plate 32.

[0095] In this configuration, the tip of the push button (release button 34b) does not protrude beyond the upper surface of the top plate 32, which prevents accidental pressing of the push button (release button 34b) during the installation of the electric shielding device corresponding to the roller screen 10 and vertical blind 100, or at other times.

[0096] [4] In addition, the above embodiments include, in addition to the contents described in any of [1] to [3] above or a combination thereof, The second board is a charge control board 34 that can be controlled to enter a sleep mode in which the power output from the battery 40 is reduced. Preferably, the push button is a release button 34b for canceling sleep mode.

[0097] With this configuration, the sleep mode of the battery 40 can be easily released by pressing the release button 34b. Furthermore, since the release button 34b is located in the recessed portion 32a and its tip does not protrude beyond the upper surface of the top plate 32, it is possible to reduce the likelihood of accidental operation that would cause the sleep mode to be released unintentionally.

[0098] [5] In addition, the above embodiments include, in addition to the contents described in any of [1] to [4] above or a combination thereof, A pair of end support members (a pair of side bracket sets 24, 24A) are provided to support both ends of the shielding drive mechanism (winding mechanism 50, slat drive mechanism 110). One of the pair of end support members (a pair of side bracket sets 24, 24A) corresponds to the case cover 244A. Preferably, the case cover 244A is provided with a detachable charging port 244A1 having a charging port 244Ad to which an external charging cord 90 is connected when charging the battery 40, 40A.

[0099] In this configuration, the charging attachment / detachment part 244A1 can be made detachable in the case cover 244A. Therefore, it is possible to replace the charging attachment / detachment part 244A1 with another attachment / detachment part (for example, the light receiving attachment / detachment part 244A2) or with a new charging attachment / detachment part 244A1, thereby improving the convenience of the electric shielding device.

[0100] Furthermore, the contents of the above embodiment can also be understood as follows, and it is also possible to produce the following effects. [6] That is, An electric shading device for a roller screen 10 and a vertical blind 100, comprising a light-blocking material (screen 70, slats 120) for blocking external light, a storage and deployment member (winding cylinder, drive shaft) for storing or deploying the light-blocking material (screen 70, slats 120), and a shading drive mechanism (winding mechanism 50, slat drive mechanism 110) equipped with a motor 53 that provides driving force to drive the storage and deployment member (winding cylinder, drive shaft), A rechargeable battery 40,40A that supplies power to drive the motor 53, A frame body 21 housing a circuit board unit 30 which includes a battery 40, 40A and a circuit board housing case 31, Equipped with, The circuit board unit 30 includes a cover member (top plate 32) that covers the circuit boards (voltage conversion board 33, charge control board 34) housed in the circuit board storage case 31. The cover member (top plate 32) is equipped with a push-button (release button 34b) that can be pressed into place on its surface. The covering member (top plate 32) is exposed on the opening surface of the frame body 21. The frame body 21 is provided with charging ports 244d, 244e, and 244Ad exposed, to which an external charging cord 90 can be connected. It is preferable that the power supply can be switched on by pressing the push button (release button 34b) while the power is off, and that the power supply can also be switched on by applying power to the charging ports 244d, 244e, and 244Ad while the power is off.

[0101] In this way, because the cover member (top plate 32) is exposed on the opening surface of the frame body 21, the push button (release button 34b) can be easily pressed by the user. As a result, even when the power is off, it is possible to easily switch the power supply state from batteries 40, 40A on and off. [Explanation of Symbols]
