Summary of the Invention

Problems to be Solved by the Invention

[0004] The length of the power cable required for wiring from the motorized shading device to the external power source varies depending on the usage environment of the motorized shading device. Therefore, the power cable is configured to have a relatively sufficient length that can accommodate various usage environments. If the length of the power cable required for wiring from the motorized shading device to the external power source is short, a surplus portion is generated in the power cable. In this case, the surplus portion of the power cable may degrade the design appearance.

[0007] The above-mentioned motorized shielding device is attached to the longitudinal end of the frame and includes a cap that closes the power supply component placement area and the cable storage area, and the cap may include an outlet for leading the power supply cable out from the cable storage area toward the outside of the frame.

[0008] In the above-described electric shielding device, the cable storage section may be open along the longitudinal direction of the frame. In the above-described electric shielding device, the frame is attached to the mounting surface via a bracket attached to the mounting surface, and the cable storage portion is provided with an engaging portion that engages with the bracket, and the engaging portion may be configured to form the opening.

[0009] The above-mentioned electric shielding device may include a cover member that is detachably attached to the cable storage section so as to close the opening. The above-described electric shielding device includes a clamp that holds the power cable inside the cable storage section, and the clamp may be configured to grip the power cable at a position closer to the power supply component than the folded-back position located inside the cable storage section.

[0010] A frame for solving the above problems is a frame that is attached to a mounting surface and holds a support member that supports a shielding material, and comprises a power supply component arrangement section where a power supply component to which a power cable is connected is arranged, and a cable storage section in which the power supply cable connected to an external power supply can be folded back and stored.

[Modes for carrying out the invention]

[0013] [First Embodiment of Electric Shielding Device and Frame] A first embodiment of the electric shielding device and frame will be described with reference to Figures 1 to 5. As shown in Figure 1, the first embodiment of the electric shielding device is a vertical blind 1. The vertical blind 1 includes a frame 2, a bracket 3, and a cap 4. The frame 2 extends along the longitudinal direction D1. The frame 2 is attached to a mounting surface S1 via the bracket 3. The bracket 3 is fixed to the mounting surface S1 by a fixing member such as a screw. In the first embodiment, the mounting surface S1 is a ceiling surface, but it may also be a window frame or a wall surface. The caps 4 are attached to both end portions of the frame 2 in the longitudinal direction D1.

[0014] The vertical blind 1 includes a plurality of slats 5. The slats 5 are made of, for example, a material having light shielding properties or semi-transparency that partially transmits light. The slats 5 are suspended from the frame 2 via runners 6 (see Figure 2) which will be described later. The slat 5 is an example of a shielding member included in the electric shielding device.

[0015] The vertical blind 1 includes a power cable CA. The power cable CA is connected to an external power source PS such as an electrical outlet. The power cable CA supplies electric power from the external power source PS to various electric devices included in the vertical blind 1. The vertical blind 1 drives the slats 5 using the electric power supplied via the power cable CA.

[0016] As shown in Figure 2, the frame 2 includes a rail portion 2A, a power component arrangement portion 2B, and a cable storage portion 2C. The rail portion 2A, the power component arrangement portion 2B, and the cable storage portion 2C extend along the longitudinal direction D1 of the frame 2. The rail portion 2A, the power component arrangement portion 2B, and the cable storage portion 2C are arranged at mutually different positions in the direction intersecting the longitudinal direction D1 of the frame 2.

[0017] Specifically, in the first embodiment, the rail portion 2A, the power supply component arrangement portion 2B, and the cable storage portion 2C are arranged at positions different from each other in the plane direction orthogonal to the longitudinal direction D1 of the frame 2. The rail portion 2A is located on the indoor side and the lower side in a cross-sectional view orthogonal to the longitudinal direction D1 of the frame 2. The power supply component arrangement portion 2B is located on the outdoor side relative to the rail portion 2A. The cable storage portion 2C is located above the rail portion 2A and on the indoor side relative to the power supply component arrangement portion 2B. Further, the cable storage portion 2C protrudes upward beyond the power supply component arrangement portion 2B.

[0018] The rail portion 2A has a concave shape that opens downward along the longitudinal direction D1. The power supply component arrangement portion 2B has a concave shape that opens toward the outdoor side along the longitudinal direction D1. The cable storage portion 2C has a concave shape that opens upward along the longitudinal direction D1. The cable storage portion 2C includes an engagement portion 2D that engages with the bracket 3. Further, the cable storage portion 2C includes an opening 2E that extends along the longitudinal direction D1 and faces upward. The engagement portion 2D forms the opening 2E. The rail portion 2A, the power supply component arrangement portion 2B, and the cable storage portion 2C are closed at the end of the frame 2 by a cap 4 (see FIG. 5).

[0019] The rail portion 2A holds the runner 6. Specifically, the rail portion 2A includes a runner rail 2R extending along the longitudinal direction D1 on each of two opposing inner side surfaces. A plurality of runners 6 are arranged on the runner rail 2R. The runner 6 includes a suspension shaft 6A for suspending and supporting the slat 5. The runner 6 is an example of a support member that supports the shielding material in the electric shielding device. The runner 6 includes two rollers 6B. The rollers 6B are arranged on the runner rail 2R of the rail portion 2A.

[0020] The vertical blind 1 comprises a tilt shaft 7 and a drive shaft 8. The tilt shaft 7 and the drive shaft 8 are supported by caps 4 attached to both ends of the frame 2. The tilt shaft 7 and the drive shaft 8 are inserted through each runner 6. The tilt shaft 7 rotates the slat 5 by rotating the suspension axis 6A of the runner 6. The drive shaft 8 moves the slat 5 by moving the runner 6 along the runner rail 2R within the rail section 2A.

[0021] Figure 3 shows an example of component placement within the power supply component placement section 2B. As shown in Figure 3, the vertical blind 1 comprises a first motor 7M, a second motor 8M, a power supply board 9, and a control board 10. These components are arranged in the power supply component placement section 2B. The first motor 7M rotates the tilt shaft 7. The second motor 8M rotates the drive shaft 8.

[0022] A power cable CA is connected to the power supply board 9. Power is supplied to the power supply board 9 from an external power supply PS via the power cable CA. The power supply board 9 supplies power from the external power supply PS to the first motor 7M, the second motor 8M, and electrical equipment such as the control board 10. The power supply board 9 is an example of a power supply component. Note that in Figure 3, the power cable CA is shown with a dashed line, and the power supply path from the power supply board 9 to the first motor 7M is not shown.

[0023] The control board 10 controls the operation of various electrical devices provided by the vertical blind 1 in response to operation input from a remote control device, such as a remote control (not shown). For example, the cap 4 is equipped with a light receiving unit 4A (see Figure 1) for receiving operation input from a remote control device. Alternatively, instead of the cap 4 being equipped with a light receiving unit 4A, an external light receiving unit connected to the control board 10 by wire may be placed outside the frame 2.

[0024] As shown in Figures 3 and 4, a through-hole 2H is provided in the upper part of the power supply component placement section 2B. The power cable CA is routed from the power supply component placement section 2B through the through-hole 2H to the upper part of the frame 2. As shown in Figure 4, the power cable CA routed from the power supply component placement section 2B is routed through the internal space of the cap 4 into the cable storage section 2C of the frame 2. Note that, for convenience, the bracket 3 is not shown in Figure 4.

[0025] The power cable CA is routed inside the cable storage section 2C, folded at any desired folding position TB. Specifically, any excess portion of the power cable CA when it is connected to the external power supply PS is stored inside the cable storage section 2C in a folded state. Therefore, the cable storage section 2C has sufficient space to accommodate the folded power cable CA.

[0026] As shown in Figure 4, the cable storage section 2C is equipped with a clamp 2F. The clamp 2F holds the power cable CA by clamping it inside the cable storage section 2C. Specifically, the clamp 2F clamps the power cable CA at a position closer to the power supply board 9 than the folded-back position TB of the power cable CA located inside the cable storage section 2C.

[0027] As shown in Figures 4 and 5, the cap 4 is provided with a notched outlet 4B. The cap 4 is configured to allow the power cable CA, which is stored in the cable storage section 2C, to be led out from the outlet 4B toward the outside of the frame 2. The power cable CA, which is folded back in the cable storage section 2C, is led out to the outside (sideways) of the frame 2 through the outlet 4B provided in the cap 4. The power cable CA led out to the outside of the frame 2 is connected to an external power supply PS.

[0028] As shown in Figures 2 and 4, the vertical blind 1 includes a cover member 11. The cover member 11 is a flexible, plate-shaped member. The cover member 11 is, for example, a transparent or translucent resin member. The length of the cover member 11 is shorter than the total length of the cable storage section 2C. The cover member 11 is detachably attached to the cable storage section 2C so as to close the opening 2E of the cable storage section 2C. For example, the cover member 11 is attached to the cable storage section 2C after the power cable CA has been folded and stored in the cable storage section 2C.

[0029] As shown in Figure 2, for example, the width of the cover member 11 is greater than the width of the opening 2E, i.e., the distance between the engaging portions 2D. As a result, the cover member 11 is locked into the cable storage portion 2C by the engaging portions 2D. The cover member 11 prevents the power cable CA from protruding above the opening 2E in the cable storage portion 2C. The cover member 11, which is locked into the cable storage portion 2C by the engaging portions 2D, can also be slid within the cable storage portion 2C.

[0030] [Wiring method for power cable CA in the first embodiment] Referring to Figure 4, an example of how to route the power cable CA is explained. The routing of the power cable CA begins before the frame 2 is attached to the bracket 3.

[0031] First, the power cable CA, connected to the power supply board 9 located in the power supply component placement section 2B, is pulled out from the power supply component placement section 2B to the top of the frame 2 through the through hole 2H. Next, the power cable CA is routed into the cable storage section 2C through the internal space of the cap 4. Then, the power cable CA is held in place by a clamp 2F provided in the cable storage section 2C. At this time, the holding position of the power cable CA by the clamp 2F is determined so that, within the range from the connection point with the power supply board 9 to the holding position, excessive tension is not applied and excessive slack does not occur.

[0032] Next, in the cable storage section 2C, the power cable CA is folded back at an arbitrary folding position TB and led out of the frame 2 through the outlet 4B of the cap 4. Then, the cover member 11 is attached over the power cable CA stored in the cable storage section 2C to prevent the power cable CA from protruding above the opening 2E. In this state, the frame 2 is attached to the bracket 3.

[0033] Then, the length of the power cable CA that has been led out of frame 2 is adjusted by pushing it back into frame 2 or by pulling the power cable CA further out of frame 2. At this time, as shown by the dashed line in Figure 4, the length of the power cable CA that has been folded back and stored in the cable storage section 2C is adjusted so that the folding position TB of the power cable CA has been folded back and stored in frame 2 is changed. Finally, the wiring of the power cable CA is completed by connecting the power cable CA to the external power supply PS.

[0034] [Effects of the First Embodiment] (1-1) In the vertical blind 1, the cable storage section 2C is configured to allow the excess portion of the power cable CA connected to the external power supply PS to be folded back and stored. This allows the length of the power cable CA led out to the outside of the frame 2 to be adjusted, thereby suppressing deterioration of the design due to the excess portion of the power cable CA.

[0035] (1-2) The power supply component placement section 2B and the cable storage section 2C extend along the longitudinal direction D1 of the frame 2 and are positioned at different locations in the direction intersecting the longitudinal direction D1. If the power supply component placement section 2B and the cable storage section 2C were to be aligned coaxially along the longitudinal direction D1, it may be difficult to secure sufficient space in the cable storage section 2C to adjust the length of the power cable CA led out to the outside of the frame 2. In this regard, by positioning the power supply component placement section 2B and the cable storage section 2C at different locations in the direction intersecting the longitudinal direction D1, sufficient length of the cable storage section 2C can be secured.

[0036] (1-3) The cap 4 is equipped with an outlet 4B, which allows the power cable CA stored in the cable storage section 2C to be led out of the frame 2 without excessive bending. Furthermore, when adjusting the length of the power cable CA led out of the frame 2, the operation of pushing the power cable CA into the frame 2 and the operation of pulling the power cable CA out of the frame 2 can be easily performed.

[0037] (1-4) The cable storage section 2C is provided with an opening 2E that extends along the longitudinal direction D1. This allows the worker to route the power cable CA inside the cable storage section 2C through the opening 2E. For example, the worker can clamp the power cable CA with the clamp 2F inside the cable storage section 2C through the opening 2E.

[0038] (1-5) The cable storage section 2C is provided with an engaging portion 2D that forms an opening 2E. The engaging portion 2D engages with the bracket 3. With the above configuration, the worker can use the opening 2E formed by the engaging portion 2D to route the power cable CA inside the cable storage section 2C.

[0039] (1-6) A cover member 11 is attached to the cable storage section 2C so as to close the opening 2E. The cover member 11 prevents the power cable CA stored in the cable storage section 2C from protruding above the opening 2E. This makes it easy to attach the frame 2 to the bracket 3. It also helps to prevent deterioration of the aesthetic appearance.

[0040] (1-7) The cable storage section 2C is equipped with a clamp 2F, which allows the power cable CA to be held within the cable storage section 2C. In this case, the clamp 2F is configured to clamp the power cable CA at a position closer to the power supply board 9 than the folding position TB within the cable storage section 2C. As a result, the length of the power cable CA led out to the outside of the frame 2 is adjusted only by the portion of the power cable CA closer to the external power supply PS than the clamp 2F. Therefore, it is possible to suppress the load applied to the portion of the power cable CA closer to the power supply board 9 than the clamp 2F when adjusting the length of the power cable CA led out to the outside of the frame 2. For example, it is possible to suppress excessive load on the connection part between the power supply board 9 and the power cable CA.

[0041] [Second Embodiment of Electric Shielding Device and Frame] A second embodiment of the electric shielding device and frame will be described with reference to Figures 6 to 9. As shown in Figure 6, a second embodiment of the electric shielding device is a roller screen 21. The roller screen 21 comprises a frame 22 and a bracket 23. The frame 22 extends along the longitudinal direction D2. The frame 22 is attached to a mounting surface S2 via the bracket 23. The bracket 23 is fixed to the mounting surface S2 by fastening members such as screws. In the second embodiment, the mounting surface S2 is a ceiling surface, but it may also be a window frame or a wall surface.

[0042] The roll screen 21 comprises a cap 24, a bearing member 25, a winding pipe 26, and a screen 27. The cap 24 is attached to both ends of the frame 22 in the longitudinal direction D2. The cap 24 extends downward from the frame 22. The bearing member 25 is attached to the cap 24 below the frame 22. The bearing member 25 rotatably supports the winding pipe 26. The winding pipe 26 is stretched between the bearing members 25 attached to each cap 24. That is, the winding pipe 26 is held by the frame 22 via the cap 24 and the bearing members 25. The screen 27 is connected to the winding pipe 26. A weight bar 28 is positioned at the lower end of the screen 27. The screen 27 is an example of a shielding material provided in an electric shielding device. The winding pipe 26 is an example of a support member that supports the shielding material in an electric shielding device.

[0043] The winding pipe 26 has a motor unit 29 inside it. The motor unit 29 rotates the winding pipe 26. The winding pipe 26 rotates due to the motor unit 29, thereby winding and unwinding the screen 27.

[0044] The roller screen 21 is equipped with a power cable CA. The power cable CA is connected to an external power supply PS. The power cable CA supplies power from the external power supply PS to the various electrical components of the roller screen 21, including the motor unit 29. The roller screen 21 raises and lowers the screen 27 using the power supplied via the power cable CA.

[0045] As shown in Figure 7, the frame 22 includes a power supply component placement section 22A and a cable storage section 22B. The power supply component placement section 22A and the cable storage section 22B extend along the longitudinal direction D2 of the frame 22. The power supply component placement section 22A and the cable storage section 22B have a space that communicates vertically. The power supply component placement section 22A is located below the cable storage section 22B. The cable storage section 22B includes an engaging portion 22C that engages with the bracket 23. The cable storage section 22B also extends along the longitudinal direction D2 and has an opening 22D that faces upward. The engaging portion 22C forms the opening 22D. The power supply component placement section 22A and the cable storage section 22B are closed at the ends of the frame 22 by caps 24.

[0046] A circuit board case 30 is placed in the power supply component placement section 22A. The circuit board case 30 is locked inside the power supply component placement section 22A. The circuit board case 30 comprises a base 31 and a cover 32. For example, a power supply board 33 or a control board 34, or both, is placed on the base 31. The cover 32 covers the base 31. The cover 32 has through holes 32H for passing wires (e.g., power cables CA) connected to the power supply board 33 or control board 34 placed on the base 31.

[0047] A power cable CA is connected to the power supply board 33. Power is supplied to the power supply board 33 from an external power supply PS via the power cable CA. The power supply board 33 supplies power from the external power supply PS to electrical equipment such as the motor unit 29 and the control board 34. The power supply board 33 is an example of a power supply component.

[0048] The control board 34 controls the operation of various electrical devices equipped in the roll screen 21 in response to operation input from a remote control device, such as a remote control (not shown). For example, the roll screen 21 is equipped with an external light receiving unit located outside the frame 22 as a device for receiving operation input from a remote control device. The external light receiving unit is connected to the control board 34 by wire.

[0049] As shown in Figure 8, the power supply component placement section 22A houses a first board case 30A containing a power supply board 33 and a second board case 30B containing a control board 34. The power cable CA is routed upward from the power supply board 33 housed in the first board case 30A towards the cable storage section 22B. For convenience, the bracket 23 is not shown in Figure 8.

[0050] The power cable CA, which is pulled out into the cable storage section 22B, is routed on the lids 32 of the first board case 30A and the second board case 30B, folded at any folding position TB. Specifically, any excess portion of the power cable CA when it is connected to the external power supply PS is stored inside the cable storage section 22B in a folded state. Therefore, the cable storage section 22B has enough space to accommodate the folded power cable CA.

[0051] As shown in Figure 9, the caps 24 attached to each end of the frame 22 are divided into a lower cap 24A and an upper cap 24B, although the lower cap 24A and the upper cap 24B may be integrally formed. The lower cap 24A closes the power supply component placement section 22A and supports the winding pipe 26 via a bearing member 25 (not shown in Figure 9). The lower cap 24A also closes a portion of the cable storage section 22B. The upper cap 24B, together with the lower cap 24A, closes a portion of the cable storage section 22B.

[0052] The upper cap 24B is provided with a notched outlet 24C. The upper cap 24B is configured to allow the power cable CA, which is stored in the cable storage section 22B, to be led out from the outlet 24C toward the outside of the frame 22. The power cable CA, which is folded back in the cable storage section 22B, is led out to the outside (sideways) of the frame 22 through the outlet 24C provided in the upper cap 24B (see Figure 8). The power cable CA led out to the outside of the frame 22 is connected to an external power supply PS.

[0053] [Wiring method for power cable CA in the second embodiment] An example of how to route the power cable CA will be explained with reference to Figure 8. The routing of the power cable CA begins before the frame 22 is attached to the bracket 23.

[0054] First, the power cable CA connected to the power supply board 33 is pulled upward from the first board case 30A located in the power supply component placement section 22A toward the cable storage section 22B. Next, in the cable storage section 22B, the power cable CA is folded back at an arbitrary folding position TB and led out of the frame 22 through the outlet 24C of the cap 24. In this state, the frame 22 is attached to the bracket 23.

[0055] Then, the length of the power cable CA that has been led out of the frame 22 is adjusted by pushing it back into the frame 22 or by pulling the power cable CA further out of the frame 22. At this time, as shown by the dashed line in Figure 8, the length of the power cable CA that has been folded back and stored in the cable storage section 22B is adjusted so that the folding position TB of the power cable CA has been folded back and stored in the cable storage section 22B changes. Finally, the wiring of the power cable CA is completed by connecting the power cable CA to the external power supply PS.

[0056] [Effects of the second embodiment] (2-1) The roller screen 21 can also obtain effects similar to those shown in (1-1) to (1-5) in the first embodiment.

[0057] [Example of changes] Each of the above embodiments can be implemented with the following modifications. Each of the above embodiments and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0058] In the second embodiment as well, the cover member 11 may be attached to the cable storage section 22B so as to close the opening 22D. This makes it possible to obtain the same effect in the roll screen 21 as in (1-6) shown in the first embodiment. In the first and second embodiments, the cover member 11 may be omitted.

[0059] In the second embodiment, the roll screen 21 may have a configuration similar to that of the clamp 2F that holds the power cable CA inside the cable storage section 22B. For example, the clamp 2F may be provided on the inner surface of the frame 22, or on the upper surface of the lid 32 of the circuit board case 30. This makes it possible to obtain the same effects as (1-7) shown in the first embodiment with the roll screen 21. Note that the clamp 2F may be omitted in the first and second embodiments.

[0060] In the first embodiment, instead of having an engaging portion 2D in the cable storage portion 2C, the frame 2 may have an engaging portion 2D in a portion other than the cable storage portion 2C that engages with the bracket 3. Similarly, in the second embodiment, instead of having an engaging portion 22C in the cable storage portion 22B, the frame 22 may have an engaging portion 22C in a portion other than the cable storage portion 22B that engages with the bracket 23.

[0061] In the first embodiment, instead of the cable storage section 2C having a concave shape with an opening 2E, the upper part of the cable storage section 2C may be a hollow cylindrical shape with the upper part closed. Similarly, in the second embodiment, instead of the cable storage section 22B having an opening 22D, the upper part of the cable storage section 22B may be closed.

[0062] In the first embodiment, the outlet 4B of the cap 4 may be omitted. In this case, the power cable CA is routed out from the frame 2 so as to go over the cap 4. Similarly, in the second embodiment, the outlet 24C of the upper cap 24B may be omitted.

[0063] In the first embodiment, the power supply component placement section 2B and the cable storage section 2C may be configured to be coaxial along the longitudinal direction D1, provided that the length of the power supply cable CA led out to the outside of the frame 2 can be sufficiently adjusted within the cable storage section 2C. Similarly, in the second embodiment, the power supply component placement section 22A and the cable storage section 22B may be configured to be coaxial along the longitudinal direction D2.

[0064] The power supply components are not limited to the power supply board 9 in the first embodiment and the power supply board 33 in the second embodiment. The power supply components can be any electrical device to which the power cable CA is connected, such as an AC adapter.

[0065] The motorized shading device is not limited to vertical blinds 1 and roller screens 21. For example, the motorized shading device may be a pull-up curtain, pleated screen, horizontal blind, vertical pleated screen, vertical roller screen, curtain rail, accordion curtain, panel curtain, etc. [Explanation of Symbols]
