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, in the motorized shading device as disclosed in Patent Document 1, there are 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 is equipped with a battery, and uses power supplied from this battery to operate electrically operated parts such as the lifting motor (30). In such a battery-powered electric shielding device, a power cord is connected to the head unit when charging the battery. At that time, it is desirable that the device be configured to allow for easy connection of the power cord.

[0006] However, if, for example, the charging port for connecting the power cord is located on the front of the head unit, then it is necessary to manufacture two types: one with the charging port on the left side of the head unit and another with the charging port on the right side of the head unit.

[0007] The present invention has been made in accordance with the above circumstances, and its purpose is to provide an electrically operated shielding device that can be used as a type in which the charging port is located on either the left or right side by replacing the component having the charging port. [Means for solving the problem]

[0008] 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; a shielding drive mechanism equipped with a motor that provides a driving force for driving the storage and deployment member; a rechargeable battery for supplying power to drive the motor; a pair of end support members for supporting both ends of the shielding drive mechanism; and a power supply bracket integrally provided with one of the pair of end support members and having a charging port to which an external charging cord is connected when charging the battery, wherein the charging port is provided within a replaceable charging range that allows charging when the power supply bracket is applied to the other end support member. [Effects of the Invention]

[0009] According to the present invention, it is possible to provide an electrically operated shielding device that can be used as a type in which the charging port is located on either the left or right side by replacing the component having the charging port. [Brief explanation of the drawing]

[0011] Hereinafter, a roll screen 10 as an electric 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.

[0012] (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, with a part of a shield 60 omitted. FIG. 2 is a cross-sectional view of the roll screen 10 shown in FIG. 1, and is a view showing a state cut along the longitudinal direction of an upper frame portion 20.

[0013] The roll screen 10 is mainly used for window frames or partitions, and in particular, the roll screen 10 in the present embodiment is of a type powered by a battery 40. For this reason, since it can be easily installed even in a place where there is no nearby power outlet, it can be installed outdoors and in various other places compared with the conventional type that is powered from a power outlet.

[0014] 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 includes a frame body 21, a board unit 30, and a battery 40.

[0015] (1-1. Regarding Frame Body 21) Figure 3 is a perspective view showing the upper frame portion 20. Figure 4 is a cross-sectional view showing a state in which the long frame 22 of the upper frame portion 20 is cut in the vicinity of the board unit 30.

[0016] The frame body 21 includes a long frame 22, an upper bracket 23, and a pair of side bracket assemblies 24. The long frame 22 is an elongated member (an example of a shaped material), and its cross section is provided in a frame shape with an open upper side. For this reason, the long frame 22 is provided with an inner frame portion 22a in which the board unit 30 and the battery 40 can be disposed. The inner frame portion 22a is provided with a board disposition portion 25 and a battery disposition portion 26 as will be described later.

[0017] The upper bracket 23 is a member that holds the long frame 22 and is fixed to a ceiling (not shown) or a ceiling-side frame attached to the ceiling via, for example, screws or the like. The upper bracket 23 has hook portions 23a at both end sides in the front-rear direction, and the hook portions 23a engage with flange portions 22b located on the upper side of the long frame 22. Thereby, the upper bracket 23 holds the long frame 22, and the long frame 22 is fixed to the ceiling side via the upper bracket 23.

[0018] The pair of side bracket assemblies 24 are members that are fixed to both end sides of the long frame 22 and protrude downward from the long frame 22. The pair of side bracket assemblies 24 rotatably support a rotation support member 51 for pivotally supporting the winding tube 55 of the winding mechanism 50 on the lower side of the long frame 22. The pair of side bracket assemblies 24 correspond to end support members.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] (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.

[0038] 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.

[0039] 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.

[0040] 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).

[0041] (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.

[0042] 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.

[0043] 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.

[0044] Furthermore, the top plate 32 is a plate-shaped member that closes the opening on the top side of the circuit board housing case 31. As shown in Figure 8, the top plate 32 is provided with a recessed portion 32a that is recessed below the surrounding area. Below this recessed portion 32a is an insertion hole 32b, through which the release button 34b, which will be described later, is inserted.

[0045] 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. In addition, 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.

[0046] 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. As a result, the protrusions 33a of the voltage conversion board 33 and the protrusions 34a of the charge control board 34 are arranged in an alternating pattern. This makes it possible to reduce the vertical height of the board unit 30.

[0047] In addition to the protrusion 34a mentioned above, the charging control board 34 also has a release button 34b mounted on it. The release button 34b is a button for releasing the sleep mode, which is activated when the power output from the battery 40 is reduced. 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 beyond the upper surface of the top plate 32.

[0048] 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.

[0049] (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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] (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.

[0057] (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.

[0058] (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).

[0059] (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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] (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.

[0064] (3-1. Regarding vertical blinds 100) 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.

[0065] 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.

[0066] 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.

[0067] 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 end support member and the pair of side bracket sets 24.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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).

[0079] 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, an infrared light receiving board may be placed in the above-mentioned space for the circuit board instead of the charging control board 34. When the infrared light 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 equipped with a charging port 244Ad, or a light receiving attachment / detachment part 244A2 capable of receiving infrared rays.

[0080] (3-2. Installation using the dual-purpose type and suspension cord 200) 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] This aims to achieve both improved ease of installation for the roller screen 10 and protection against damage to the screen 70.

[0085] (3-3. Regarding the 300 Electric Curtain Rail) Furthermore, the electric shielding device of the present invention may also be, for example, an electric curtain rail 300. The configuration of such an electric curtain rail 300 is shown in Figure 14. Figure 14 is a perspective view showing the configuration of an electric curtain rail 300 according to a modified example of the present invention. The electric curtain rail 300 shown in Figure 14 mainly consists of a rail unit 310, a runner 320, a curtain 330, and a motor unit 340.

[0086] The rail unit 310 corresponds to the upper frame section 20 described above. However, in this electric curtain rail 300, the rail unit 310 does not have a circuit board unit 30 or a battery 40, which are provided in the motor unit 340, which will be described later. Therefore, the rail unit 310 corresponds to the frame body 21 obtained by removing the circuit board unit 30 and the battery 40 from the upper frame section 20.

[0087] This rail unit 310 comprises a curtain rail 311, an upper bracket 312, a left pulley section 313, and a right pulley section 314. The curtain rail 311 is a long member, and its cross-section is a frame shape with an opening at the bottom. The opening at the bottom serves as a guide groove 311a that causes the suspension shaft 321 of the runner 320 (described later) to protrude downward, and this guide groove 311a is formed along the longitudinal direction of the curtain rail 311.

[0088] Furthermore, the upper bracket 312 corresponds to the upper bracket 23 and holds the curtain rail 311 while being fixed to a ceiling (not shown) or a ceiling-side frame attached to the ceiling, for example, via screws.

[0089] Furthermore, the left pulley section 313 is a component located on the left side of the curtain rail 311 in Figure 14, and a left pulley is rotatably housed inside it. A conveyor belt (not shown) is wrapped around this left pulley. The conveyor belt is arranged on the inner frame of the curtain rail 311 such that the forward and return sides face each other across the guide groove 311a. The conveyor belt corresponds to the storage and deployment member, but other components may also be included in the storage and deployment member. The rail unit 310 and the motor unit 340 correspond to the shielding drive mechanism, but other components necessary for driving may also be included in the shielding drive mechanism.

[0090] Furthermore, the right pulley section 314 is a component located on the left side of the curtain rail 311 in Figure 14, and, like the left pulley section 313, the left pulley is rotatably housed inside it. A conveyor belt (not shown) is routed around this right pulley. In addition, the left pulley section 313 receives driving force from the motor 342 of the motor unit 340.

[0091] The runner 320 is a component that moves along the curtain rail 311 to unfold or retract the curtain 330. The runner 320 has running rollers (not shown) positioned on the inner frame of the curtain rail 311, with the running rollers positioned on either side of the guide groove 311a. The runner 320 is also provided with a suspension shaft 321 that protrudes downward from the guide groove 311a. The curtain 330 is suspended from this suspension shaft 321.

[0092] Here, the runner 320 is provided with, for example, an extension runner 320T closest to the left pulley portion 313 and a driven runner 320S. The extension runner 320T has a joint portion (not shown) located on the inner frame of the curtain rail 311, and this joint portion is connected to the conveyor belt. Therefore, the extension runner 320T is configured to move forward or backward in accordance with the forward or backward movement of the conveyor belt. The extension runner 320T is also provided with an arm portion 322, from which the left end of the curtain 330 is suspended. There are multiple driven runners 320S, which are sequentially extended as the extension runner 320T moves.

[0093] Furthermore, the curtain 330 is compatible with shading materials and is made from a fabric that can block or dim external light.

[0094] Furthermore, the motor unit 340 has a cylindrical housing portion 341, and a motor 342 and other components are built inside. The motor 342 is the part that provides the driving force to drive the conveyor belt described above.

[0095] A battery unit 350 is connected to this motor unit 340. The battery unit 350 has a battery case 351, and a battery 352 is built inside the battery case 351.

[0096] Furthermore, a power supply bracket 360 is connected to the lower side of the battery unit 350. A charging port 361, similar to the charging port 244d described above, is provided on the lower horizontal surface of this power supply bracket 360. Therefore, the battery 352 can be charged by inserting an external charging cord 90 into this charging port 361.

[0097] In the configuration shown in Figure 14, the aforementioned replacement charging area R1 is located on the underside of the power supply bracket 360, where the charging port 361 is provided. However, this replacement charging area R1 may also be located on the side of the power supply bracket 360. In that case, the charging port 361 would also be located on the side of the power supply bracket 360.

[0098] In addition to the charging port 361, the underside of the power supply bracket 360 also has setting buttons 362 for, for example, selecting the operating mode and making various settings. In the configuration shown in Figure 14, there are two setting buttons 362, but the number can be any number. Also, in the configuration shown in Figure 14, the setting buttons 362 are located in recesses 363 that are recessed from the underside of the power supply bracket 360. However, a configuration without recesses 363 is also acceptable.

[0099] Furthermore, a circuit board (not shown) is arranged inside the power supply bracket 360. This circuit board may correspond to the charging control board 34 described above, or to the voltage conversion board 33, or it may correspond to the settings made by the setting button 362. In addition, it is preferable that the power supply bracket 360 is provided in a symmetrical shape in either the front-to-back direction or the left-to-right direction.

[0100] In the electric curtain rail 300 having the above configuration, for example, the motor unit 340 can be positioned on the left side of the electric curtain rail 300 instead of the right side. Even in this case, the charging port 361 will be located on the underside of the power supply bracket 360, which is integrally connected to the motor unit 340. In other words, the same power supply bracket 360 can be used on either the left or right side of the electric curtain rail 300 to provide a charging port 361.

[0101] In the configuration shown in Figure 14, the motor unit 340 and the power supply bracket 360 are not integrated into a single unit. Instead, the power supply bracket 360 can be separated and connected to the left pulley section 313. In this case as well, the same power supply bracket 360 can be used on either the left or right side of the electric curtain rail 300 to provide a charging port 361.

[0102] (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, the motorized shielding device corresponding to the roller screen 10 and the vertical blind 100 is, A light-blocking material (screen 70, slat 120) to block out external light, A shielding drive mechanism (winding mechanism 50, slat drive mechanism 110, motor unit 340) is provided, which includes a storage and deployment member (winding cylinder, drive shaft, conveyor belt) for storing or deploying the shielding material (screen 70, slat 120, curtain 330), and a motor 53 that provides driving force to drive the storage and deployment member (winding cylinder, drive shaft, conveyor belt), A rechargeable battery 40, 40A, 352 that supplies power to drive the motor 53, A pair of end support members (a pair of side bracket assemblies 24, 24A, left pulley section 313, right pulley section 314) support both ends of the shielding drive mechanism (winding mechanism 50, slat drive mechanism 110, motor unit 340), A power supply bracket 244, 244A, 360 is provided on one of the end support members (either the side bracket assembly 24, 24A, the left pulley section 313, or the right pulley section 314) of a pair of end support members (a pair of side bracket assemblies 24, 24A, the left pulley section 313, and the right pulley section 314), and has charging ports 244d, 244e, 244Ad, 361 to which an external charging cord 90 is connected when charging the batteries 40, 40A, 352. Equipped with, The charging ports 244d, 244e, 244Ad, and 361 are located within the replaceable charging range R1, which allows charging when the power supply brackets 244, 244A, and 360 are applied to the other end support member (either the side bracket assembly 24, 24A, the left pulley section 313, or the right pulley section 314).

[0103] Therefore, on either the left or right side of the roller screen 10, vertical blinds 100, and electric curtain rail 300, the same power supply brackets 244, 244A, and 360 can be swapped, and the charging cord 90 can be easily connected from the charging ports 244d, 244e, 244Ad, and 361 located in the replacement charging range R1. Thus, the electric shielding device (roller screen 10, vertical blinds 100, and electric curtain rail 300) can be used regardless of whether the charging ports 244d, 244e, 244Ad, and 361 are located on the left or right side.

[0104] Furthermore, when viewed from the front, it becomes unnecessary to manufacture two separate types: one in which the charging port is located on the left side of the upper frame 20, hanger rail 20A, and rail unit 310, and another in which the charging port is located on the right side of the upper frame 20, hanger rail 20A, and rail unit 310. This reduces manufacturing costs.

[0105] [2] In addition, in the above embodiment, in the contents of [1] above, The electric shielding device is a roller screen 10 or a vertical blind 100. The shielding material is either a screen 70 or a slat 120. The shielding drive mechanism is either a winding mechanism 50 that provides driving force to store or unfold the screen 70, or a slat drive mechanism 110 that provides driving force to store or unfold the slats 120. Preferably, the pair of end support members are a pair of side bracket sets 24, 24A that support both ends of the shielding drive mechanism (winding mechanism 50, slat drive mechanism 110).

[0106] Therefore, on either the left or right side of the roller screen 10 or vertical blind 100, the same power supply bracket 244, 244A can be swapped, and the charging cord 90 can be easily connected from the charging ports 244d, 244e, 244Ad located in the replacement charging range R1. Thus, it can be used as a type where the charging ports 244d, 244e, 244Ad are located on either the left or right side.

[0107] [3] In addition, in the above embodiment, in the contents of [1] above, The electric shielding device is an electric curtain rail 300. The shielding material is a curtain 330. The shielding drive mechanism has a rail unit 310 for storing or extending the curtain 330. Preferably, the pair of end support members are a left pulley portion 313 and a right pulley portion 314 that support one side and the other side of the shielding drive mechanism (rail unit 310), respectively.

[0108] Therefore, on either the left or right side of the electric curtain rail 300, the same power supply bracket 360 can be attached to the left pulley portion 313 and the right pulley portion 314, allowing the charging cord 90 to be easily connected from the charging port 361 located in the replacement charging range R1. Thus, it can be used as a type where the charging port 361 is located on either the left or right side.

[0109] [4] In addition, in the above embodiment, in the contents of [3] above, Preferably, the charging port 361 is provided on the lower surface of the power supply bracket 360, which is a horizontal plane.

[0110] In this configuration, for example, regardless of whether the power supply bracket 360 is attached to the left or right side of the electric curtain rail 300, the charging port 361 can be positioned on the lower surface as a horizontal plane. Therefore, it becomes easy to manufacture electric curtain rails 300 in which the charging port 361 is located on either the left or right side.

[0111] [5] In addition, the above embodiments include, in addition to the contents described in any of [1] to [3] above or a combination thereof, The replacement charging range R1 is preferably located on the lower side of the power supply brackets 244, 244A, and 360.

[0112] In this configuration, the charging ports 244d, 244Ad, and 361 can be positioned on the lower side regardless of whether the power supply brackets 244, 244A, and 360 are attached to the left or right side of the roller screen 10, vertical blinds 100, or electric curtain rail 300. Therefore, it becomes easy to manufacture roller screens 10, vertical blinds 100, and electric curtain rails 300 of which the charging ports 244d, 244Ad, and 361 can be positioned on either the left or right side.

[0113] [6] In addition, the above embodiments include, in addition to the contents described in any of [1] to [5] above or a combination thereof, Preferably, the replacement charging range R1 is provided as a pair of the front side, which is the indoor side of the power supply brackets 244, 244A, and 360, and the rear side, which is opposite the indoor side.

[0114] In this configuration, the charging ports 244d, 244Ad, and 361 can be positioned on either the front or rear side, regardless of whether the power supply brackets 244, 244A, and 360 are attached to the left or right side of the roller screen 10, vertical blinds 100, or electric curtain rail 300. Therefore, it becomes easy to manufacture roller screens 10, vertical blinds 100, and electric curtain rails 300 in which the charging ports 244d, 244Ad, and 361 are positioned on either the left or right side.

[0115] [7] In addition, the above embodiments include, in addition to the contents described in any of [1] to [6] above or a combination thereof, The electric shielding device is a roller screen 10. The shielding material is Screen 70. The storage and deployment component is a winding tube 55. The shielding drive mechanism is preferably a winding mechanism 50.

[0116] Therefore, the power supply bracket 244, which is the same component, can be swapped on either the left or right side of the roller screen 10, and the charging cord 90 can be easily connected from the charging ports 244d and 244e located in the replacement charging range R1. Thus, the roller screen 10 can be used even if the charging ports 244d and 244e are located on either the left or right side.

[0117] Furthermore, when viewed from the front, it becomes unnecessary to manufacture two separate types: one with the charging port on the left side of the upper frame 20, and another with the charging port on the right side of the upper frame 20. This reduces manufacturing costs.

[0118] [8] In addition, the above embodiments include, in addition to the contents described in any of [1] to [7] above or a combination thereof, It is preferable that the power supply brackets 244, 244A, and 360 are provided in a symmetrical shape in the front-to-back direction, connecting the front side which is the indoor side of the power supply bracket 244, 244A, and 360 with the rear side which is opposite the indoor side.

[0119] In this configuration, the power supply brackets 244, 244A, and 360 can be easily swapped between the end support member located on the left side when viewed from the front (either the side bracket assembly 24 or 24A, or the left pulley section 313 or the right pulley section 314) and the end support member located on the right side when viewed from the front (either the side bracket assembly 24 or 24A, or the left pulley section 313 or the right pulley section 314).
