  FIG. 4 is a perspective view showing the upper structure of the blind device 10 in a state where the housing box 26 and the drive mechanism 24 are omitted. FIG. 5 is a longitudinal sectional view showing an upper structure of the blind device 10, and shows a state in which the movable louver portion 16 is pulled down to open between the slats 32.

  As shown in FIGS. 2 and 5, partitioning plates 42 and 43 partition the movable louver unit 16 and the driving mechanism unit 24 provided at the lower part on the front side of the storage box 26. The partition plates 42 and 43 cover the internal space (space 34) of the housing box 26 in which the drive mechanism unit 24 is arranged from the outdoor portion where the movable louver unit 16 is arranged, so that rainwater, dust, insects, etc. 34 is a shielding plate for preventing the intrusion into the inside.

  The partition plate 42 includes a substantially horizontal extending upper plate 46 that partitions the upper side of the movable louver portion 16 and the space 34, and a substantially vertical extending rear plate 47 that partitions the rear side of the movable louver portion 16 and the space 34. Are formed in a substantially L-shaped cross section. As shown in FIGS. 3 to 5, the upper plate 46 is fastened and fixed to the brackets 48, which are metal fittings, which are screwed and fixed to the inner surfaces of the left and right rail members 28 and 29 using connection screws 50. The partition plate 42 may be directly attached and fixed to the rail members 28 and 29 without the intervention of the bracket 48. The back plate 47 is fastened and fixed to the protruding piece 52 protruding inward from the indoor side end of the inner expected surface of the rail members 28 and 29 by using a connection screw 54.

  The partition plate 43 fills a gap between the lower end of the rear plate 47 of the partition plate 42 and the intermediate frame 22e. The partition plate 43 extends in a substantially vertical direction similarly to the rear plate 47 of the partition plate 42, and partitions the rear side of the movable louver portion 16 from the space 34. As shown in FIG. 4, the partition plate 43 is fastened and fixed to the protruding piece 52 protruding inward from the indoor side end of the inner expected surface of the rail members 28 and 29 by using a connection screw 54. The boundary between the partition plate 43 and the intermediate frame 22e is sealed with a watertight material 56.

  As described above, the partition plate 43 is for filling the gap between the lower end portion of the rear plate 47 of the partition plate 42 and the intermediate frame 22e. Therefore, when there is no gap, the partition plate 43 may be omitted as shown in FIG. 6 and the back plate 47 of the partition plate 42 and the intermediate frame 22e may be connected by a watertight material 56. In other words, since the vertical length of the back surface of the movable louver portion 16 changes according to the number of slats 32 installed, for example, it is possible to determine whether or not the partition plate 43 needs to be installed according to the vertical length. High in nature.

  In this case, the blind device 10 according to the present embodiment includes a movable louver portion 16 composed of a plurality of slats 32, a drive mechanism portion 24 that moves the movable louver portion 16 up and down, an opening on the lower surface side, and at least the drive mechanism portion 24. And a partition plate 42 (43) for partitioning the movable louver portion 16 and the drive mechanism portion 24 from each other.

  Therefore, for example, as shown in FIG. 5, the movable louver portion 16 is pulled down to open the slats 32, and even if rainwater, insects, or the like enter through the gap between the slats 32, the rainwater or the like is not removed. The partition plate 42 (43) can prevent entry into the internal space (space 34) of the storage box 26. This prevents rainwater or the like from entering the drive mechanism section 24 through the gap between the slats 32 from the opening on the lower surface side even when the storage box 26 is miniaturized, for example, to improve designability. Thus, the electric motor 24a and the controller 24b constituting the drive mechanism 24 can be protected from rainwater and the like. For this reason, waterproofing of these electrical components is not required, and costs can be reduced. Moreover, even when the size of the storage box 26 is reduced, the outer wall 12 of the building, the skeleton, various structural parts, and the like on the back side of the movable louver portion 16 can be visually recognized from the outside of the room through the gap between the slats 32 of the movable louver portion 16. This can be prevented by the partition plate 42 (43). As a result, the design and quality of the blind device 10 are further improved.

  In the blind device 10, the drive mechanism 24 is provided in the space 34 extending from the upper side of the movable louver section 16 to the back side in the storage box 26, and the partition plate 42 is used to partition the upper side of the movable louver section 16. It has a plate 46 and a back plate 47 that partitions the back side of the movable louver portion 16. For this reason, it is possible to more reliably prevent rainwater or the like from entering the drive mechanism section 24 installed in the space 34 extending from the upper side to the rear side of the movable louver section 16. At this time, the back plate 47 blocks the outer wall 12 or the building of the building disposed on the back side of the movable louver unit 16 to block the space between the movable louver unit 16 and the outer wall 12 or the frame of the building where the blind device 19 is installed. The frame and the like can be hidden more reliably.

  The blind device 10 includes a pair of rail members 28 and 29 having a guide portion 44 that guides the left and right end portions of the movable louver portion 16 so as to be able to move up and down, and the partition plate 42 (43) includes a pair of rail members 28 and 29 are provided. Thereby, it is possible to more reliably partition between the outdoor space in which the movable louver portion 16 is disposed and the inside (space 34) of the blind device 10, and it is further ensured that rainwater or the like enters the drive mechanism portion 24. Can be prevented.

  At this time, since the partition plates 42 (43) are attached and fixed to the rail members 28 and 29 as shown in FIG. 3, the installation is easy and the workability is improved. However, the partition plates 42 (43) may be attached and fixed to the vertical frames 22c and 22d fixed to the left and right rail members 28 and 29, respectively, as shown in FIG.

  In the configuration example shown in FIG. 7, the partition plate 42 is fastened and fixed to the bracket 48 in which the upper plate 46 is screwed and fixed to the inner expected surfaces of the left and right rail members 28 and 29 using the connection screw 50. On the other hand, the rear plate 47 is fastened and fixed to the vertical frames (vertical frame members) 22c and 22d attached and fixed to the indoor side finding surfaces of the rail members 28 and 29 using the connection screws 54. The partition plate 42 may be attached and fixed to the vertical frames 22c and 22d via a metal fitting similar to the bracket 48. This configuration also facilitates the installation of the partition plate 42 and improves workability. In the configuration example shown in FIG. 7, the outer prospective surfaces of the rail members 28 and 29 are offset outward, and the outer prospective surfaces and the outer prospective surfaces of the vertical frames 22 c and 22 d are arranged flush with each other. Instead of the cover member 45, a cover member 58 that covers only the outdoor-side finding surfaces of the rail members 28 and 29 is attached and fixed. Thereby, the found size in the left-right direction of the blind device 10 is reduced, and the design property is further improved.

  Further, in the blind device 10, the housing box 26 is formed of an inspection plate 38 that can be opened and closed at least on the front. Therefore, the upper plate 46 of the partition plate 42 may be fixed together with the front plate 38b of the inspection plate 38 to the bracket 48 using, for example, a connecting screw 50 (see FIG. 8). In the configuration example shown in FIG. 8, a mounting piece 38 c protruding from the inner surface of the front plate 38 b of the inspection plate 38 toward the indoor side is fastened together with the upper plate 46 by the connecting screw 50. The partition plate 42 may be attached and fixed to the inspection plate 38 via a metal fitting similar to the bracket 48. With this configuration, the fixing of the inspection plate 38 and the fixing of the partition plate 42 can be performed at the same time, and workability is improved. Moreover, the inspection plate 38 and the partition plate 42 serving as the front wall of the storage box 26 are fixed by screws, so that the space 34 in the storage box 26 can be more reliably closed from the outdoor space.

  It should be noted that the present invention is not limited to the above-described embodiment, and may be freely changed without departing from the gist of the present invention.
