[0015] [A] Overview of blind shutters An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a front view and a side view of a blind shutter according to this embodiment, FIG. 2 shows a longitudinal cross-section of the blind shutter according to this embodiment, and FIG. 3 shows a cross-section of the blind shutter according to this embodiment (showing cross-sections at different heights on the left and right). FIG. 19 is an exploded perspective view of a blind shutter showing a comparative example of a case mounting method, and FIG. 19 can be referred to for the basic configuration of a blind shutter. A blind shutter is a shutter device installed on the outdoor side of a window sash WS attached to a window opening. Left and right vertical frames 1 are extended from a main body W at positions outside the widthwise ends of the window opening. A drip edge 16 is provided below the window opening, spanning between the left and right vertical frames 1. An opening surrounded by the left and right vertical frames 1 and the drip edge 16 is formed on the outdoor side of the window opening, and this opening is opened and closed by a blind (shutter curtain) 2. A case 3 is extended from the main body W above the opening. Note that in FIGS. 1 to 3, reference numeral W1 indicates a finishing wall.

[0016] In this embodiment, the vertical frame 1 is a guide rail assembly consisting of a guide rail base frame 4 fixed to the frame W and a guide rail 5 connected to the guide rail base frame 4. The shutter curtain 2 is composed of multiple slats 20 extending between the left and right guide rails 5. The multiple slats 20 are liftable and tiltable, functioning as blinds. A case support member 6 used to attach a case 3 to the vertical frame 1 is provided at an upper portion of the outer surface of the vertical frame 1. The case 3 is composed of left and right side panels 9 fixed to the case support member 6 and a case main body 3' (see FIG. 15 ) that includes left and right side portions and a front portion and is attached to the side panels 9. The case main body 3' is composed of a first member 7 and a second member 8. In this embodiment, the case support member 6, first member 7, second member 8, and side panels 9 are made of steel plates. Details of these elements will be described later.

[0017] Link mechanisms (not shown) for raising, lowering, and tilting the multiple slats 20 are located within the left and right guide rails 5. The left and right link mechanisms are operated by a drive mechanism including an electric motor M and a gearbox 10 located within the case 3. Rotating shafts located at the upper ends of the left and right link mechanisms are synchronized by a shaft 11 (see FIG. 19 ) located within the case 3. A shaft spring 11a is provided at one end of the shaft 11. Also located within the case 3 are a receiver unit 12 (attached to the main body W) that receives an opening / closing signal, and a control unit 13 that controls the electric motor M based on the signal received by the receiver unit 12. In this embodiment, the drive mechanism including the electric motor M and gearbox 10 and the control unit 13 (fixed to the gearbox 10 in this embodiment) are provided near the upper ends of the guide rails 5 and are not attached to the case 3. In this embodiment, the control unit 13 is covered on both the outdoor side and the underside by a cover 13A fixed to the guide rail base frame 4, preventing water droplets from splashing on the control unit 13 due to rainwater blowing in from below the case 3. An inner lintel (underside of the case) 14 is provided on the lower part of the case 3 facing the main body, and a back plate 15, which forms the rear surface of the case 3, is provided on the main body W. Note that in this embodiment, the inner lintel 14 may be positioned at different heights on the case 3 (see Figures 2 and 18). In this embodiment, the upper end of the back plate 15 is located slightly above the upper end of the vertical frame 1, and its lower end extends to the inner lintel 14. The inner lintel 14 and the receiver unit 12 are fixed to the back plate 15 and the main body W with screws. Both ends of the inner lintel 14 in the length direction (opening width direction) are fixed to the guide rail base frames 4 of the left and right vertical frames 1. Blind shutters themselves are well known, and Patent Documents 1 to 4 can be referred to as appropriate for the operating mechanism (including the link mechanism and drive mechanism) and basic operation of the shutter (slats 20).

[0018] [B] Vertical frame The vertical frame 1, which is made up of the guide rail base frame 4 and the guide rail 5, will now be described in detail. The guide rail base frame 4 is a long member extending in the height direction, and includes a base side 40 fixed to the body W, and an inner prospective surface 41 and an outer prospective surface 42 that extend parallel to each other from the base side 40 in a direction away from the body W in a cross-sectional view, with connecting pieces 410, 420 formed at the tip portions of the inner prospective surface 41 and the outer prospective surface 42, to which the guide rail 5 is connected (see the upper diagram in Figure 9).

[0019] The guide rail 5 is a long member extending in the height direction and includes a base side 50 at the rear end, an inner projected surface 51 extending parallel to and facing the base side 50 in a direction away from the main body W (guide rail base frame 4), an outer projected surface 52, and a front surface 53 connecting the tips of the inner projected surface 51 and the outer projected surface 52. The base side 50 is formed with connecting pieces 500 and 501 that connect to connecting pieces 410 and 420 of the guide rail base frame 4. The inner projected surface 51 of the guide rail 5 is provided with a guide groove 510 extending in the height direction (see FIGS. 2 and 9, upper diagrams). A concealing fin 511 protrudes in the front direction from the rear end of the inner projected surface 51 of the guide rail 5, and is configured to conceal the gap between the window sash WS and the inner projected surface 41 of the guide rail base frame 4 when viewed from the front (see FIGS. 3 and 9, upper diagrams).

[0020] In this embodiment, the guide rail base frame 4 is fixed to the frame W with screws S6 (FIG. 3), and the guide rail 5 is detachably connected to the guide rail base frame 4 with screws S7 (FIG. 2). The inner prospective surface 41 of the guide rail base frame 4 and the inner prospective surface 51 of the guide rail 5 form the inner prospective surface of the vertical frame 1, and the outer prospective surface 42 of the guide rail base frame 4 and the outer prospective surface 52 of the guide rail 5 are flush with each other to form the outer prospective surface (side surface) of the vertical frame 1. More specifically, the connecting piece 420 of the guide rail base frame 4 and the connecting piece 501 of the guide rail 5 are engaged, and the connecting piece 410 of the guide rail base frame 4 and the connecting piece 500 of the guide rail 5 are fixed together with screws S7 (FIG. 2) in an overlapping state. Therefore, when the blind shutter is installed, by removing the multiple screws S7 arranged along the height direction, it is possible to release the connection of the guide rail 5 to the guide rail base frame 4 and detach the guide rail 5 from the vertical frame 1.

[0021] [C] Shutter Curtain The shutter curtain 2 is made up of multiple slats 20 extending between the left and right guide rails 5. The opening is fully closed when the multiple slats 20 are in a vertical position to cover the opening, and in the fully closed state, the inclination of each slat 20 can be changed by tilting it, making it possible to control the amount of light and visibility. Also, the opening can be opened by raising all of the slats 20.

[0022] Both longitudinal ends of each slat 20 are connected to slat supports 21 located outside guide grooves 510 formed in the height direction on the inner projected surface 51 of the guide rail 5 and protruding from the projected surface. The slat supports 21 are connected to a link mechanism (not shown) that constitutes a lifting mechanism and a tilting mechanism in the internal space of the guide rail 5. The link mechanism is operated by a drive mechanism including a motor M and a gearbox 10. For details of the link mechanism and the drive mechanism, see Patent Documents 1 to 4.

[0023] By operating the link mechanism (lifting mechanism), the slat supports 21 rise, causing the slats 20 supported by the slat supports 21 to rise, and by lowering the slat supports 21, causing the slats 20 supported by the slat supports 21 to lower. When the opening is fully opened, all of the slats 20 rise to open the opening, and these slats 20 are stored in the case 3, overlapping each other in a substantially horizontal position. When the opening is fully closed, the lowest slat 20 (bottom slat 20) is in contact with or close to the drip edge 16 (see Figure 2). Furthermore, by operating the link mechanism (tilt mechanism), the slat supports 21 tilt, causing the slats 20 supported by the slat supports 21 to tilt.

[0024] In this embodiment, a cushioning rubber extending in the length direction is provided at the upper end of each slat 20 and at the upper and lower ends of the bottom slat 20, and when the opening is fully closed, two protrusions of the cushioning rubber come into contact with the adjacent slat 20, and the cushioning rubber at the lower end of the bottom slat 20 comes into contact with the drip edge 16, thereby reducing light leakage. In addition, the height dimension of the slats 20 is slightly smaller than the projected dimension of the guide rail 5, so that when the slats 20 are in a horizontal position, they fit within the projected surface of the guide rail 5 (Fig. 2).

[0025] [D] Case [D-1] Overview of case structure As shown in FIGS. 4 to 6 and 15, the case 3 according to this embodiment comprises a case main body 3' made up of a first member 7 and a second member 8, and left and right side panels 9. That is, the case 3 is composed of four members: the first member 7, the second member 8, and the left and right side panels 9. The side panels 9 of the case 3 are attached to case support members 6 fixed to upper portions of the side surfaces of the vertical frames 1 on the left and right of the opening, and the case main body 3' is supported by the side panels 9 and the case support members 6. The configurations of the case support members 6, the first member 7, the second member 8, and the side panels 9 will be described in detail below.

[0026] [D-2] Case support member As shown in FIG. 8 , the case support member 6 has a vertical base 60 extending in the front-to-rear direction. The base 60 is composed of a front (outdoor) plate-shaped portion 600, an upper band-shaped portion 601 extending rearward (toward the building frame) from the plate-shaped portion 600, and a lower band-shaped portion 602. The upper band-shaped portion 601 has an upper horizontal side 61 extending horizontally from the lower end of the upper band-shaped portion 601 and an upper vertical side 62 hanging down from the upper horizontal side 61. The lower band-shaped portion 602 has a lower horizontal side 63 extending horizontally from the upper end of the lower band-shaped portion 602 and a lower vertical side 64 rising vertically from the lower horizontal side 63. A horizontal upper side 65 is formed at the upper end of the base 60 across the entire width (front-to-rear direction), and a horizontal lower side 66 is formed at the lower end of the base 60 across the entire width (front-to-rear direction). A narrow front surface portion 67 is formed at the front (outdoor) end of the base 60 (plate-shaped portion 600) and extends over substantially the entire height of the base 60. The projection dimensions of the upper horizontal side 61 and the lower horizontal side 63 are greater than the width dimension of the front surface portion 67, and the upper vertical side 62 and the lower vertical side 64 are located outside the front surface portion 67 in a front view.

[0027] Two insertion holes 620 are formed in the upper vertical edge 62 of the case support member 6, spaced apart in the lengthwise direction (front-to-back direction), and two insertion holes 640 are formed in the lower vertical edge 64 of the case support member 6, spaced apart in the lengthwise direction (front-to-back direction). The insertion holes 620, 640 are holes for attaching the case support member 6 to upper portions of the side surfaces of the vertical frames 1 (guide rail base frames 4) on the left and right sides of the opening using screws S1. Screw holes 603, 604 are formed in the rear portions (body side portions) of the upper band-shaped portion 601 and the lower band-shaped portion 602 of the base 60, respectively. The screw holes 603, 604 are holes for attaching the side panel 9 to the case support member 6 using screws S2. Screw holes 670 are formed at the upper and lower height sides of the front surface 67. The screw holes 670 are holes for fixing the front surface portion 80 (described later) to the front surface portion 67 of the case support member 6 with screws S5. In a front view, the upper screw hole 670 is located below the upper horizontal edge 61, and the lower screw hole 670 is located above the lower horizontal edge 63. In the case support member 6 according to this embodiment, the upper band-shaped portion 601 and the lower band-shaped portion 602 are spaced apart in the vertical direction, but the upper band-shaped portion 601 and the lower band-shaped portion 602 are integrally formed via the plate-shaped portion 600, which ensures strength and improves installation workability. In addition, because the front surface portion 67 is also integrally formed, it is easy to align the installation positions with the side panel 9, the first member 7, and the second member 8.

[0028] [D-3] First member The first member 7 is connected to the second member 8 and integrated with it to form the case main body 3' of the case 3. In the case main body 3', the first member 7 is located above the second member 8. As shown in FIGS. 11 and 12, the first member 7 has a top surface portion 70, left and right trapezoidal side portions 71 extending downward from both ends of the top surface portion 70 in the width direction, and a front surface portion 72 extending downward from the front end of the top surface portion 70. A horizontal edge 710 extending inward is formed at the lower end of the side surface portion 71, and a hanging edge 711 hanging down from the horizontal edge 710 is further formed. The top surface portion 70 is gently inclined downward toward the front, and a vertical rising edge 700 is integrally formed on the base end side.

[0029] The rising edge 700 has insertion holes 701 formed across the width direction (only the insertion holes 701 at both widthwise ends are shown in FIG. 12). The insertion holes 701 are holes for attaching the rear end portion of the top surface portion 70 of the first member 7 to the body W with screws S4. A horizontal piece 720 extending rearward and a hanging piece 721 hanging down from the tip (rear end) of the horizontal piece 720 are integrally formed at the lower end of the front surface portion 72. As shown in FIG. 12, the hanging piece 721 has a plurality of insertion holes 722 formed at intervals in the width direction. The insertion holes 722 are holes for attaching the second member 8 to the first member 7 with screws S3.

[0030] The first member 7 according to this embodiment is reinforced by a reinforcing member 17. As shown in Fig. 12A, the reinforcing member 17 includes left and right brackets 170, an upper angle member 171 provided at the front ends of the left and right brackets 170 and spanning between the left and right brackets 170, and a lower angle member 172. The left and right brackets 170 include trapezoidal side portions 1700 corresponding to the shape of the side portion 71 of the first member 7, a rear piece 1701 at the rear end of the side portion 1700, a front surface 1702 at the front end of the side portion 1700, and an upper piece 1703 at the upper edge of the side portion 1700. The lower end of the lower angle iron 172 is integrally formed with a horizontal piece 1720 extending rearward and a vertical piece 1721 hanging down from the tip (rear end) of the horizontal piece 1720, with the horizontal piece 1720 positioned at the same height as the lower ends of the left and right brackets 170, and the vertical piece 1721 positioned rearward of the front faces 1702 of the left and right brackets 170 and extending downward from the lower ends of the left and right brackets 170.

[0031] Insertion holes 1704 are formed in upper portions of the rear pieces 1701 of the left and right brackets 170. The reinforcing member 17 is fixed to the body W with screws S4 in a state in which the upper portions of the rear pieces 1701 of the left and right brackets 170 are placed on the back surfaces of both widthwise ends of the rising edge 700 at the base end of the upper surface portion 70 of the first member 7 (the insertion holes 701 and 1704 are aligned). A plurality of screw holes 1722 are formed in the vertical piece 1721 of the lower angle iron 172 at intervals in the width direction. The screw holes 1722 are holes for attaching the second member 8 to the first member 7 with screws S3.

[0032] The upper pieces 1703 of the left and right brackets 170 are fixed with rivets R to the underside of both widthwise end portions of the upper surface portion 70 of the first member 7, and the side portions 1700 of the left and right brackets 170 are abutting or close to the inner surface of the horizontal edge 710 of the first member 7, and the front surfaces 1702 and angle irons 171, 172 of the left and right brackets 170 are abutting or close to the inner surface of the front surface portion 72 of the first member 7, and are positioned in the internal space of the first member 7.

[0033] [D-4] Second member The second member 8 is connected to and integrated with the first member 7 to form the case main body 3' of the case 3. In the case main body 3', the second member 8 is located below the first member 7. As shown in FIG. 13, the second member 8 has a front portion 80 and left and right side portions 81 extending rearward from both ends in the width direction of the front portion 80. The front portion 80 and the side portions 81 have the same height dimension, which is approximately the same as the height dimension of the side panels 9.

[0034] A horizontal piece 800 extending rearward and a rising piece 801 rising from the horizontal piece 800 are integrally formed at the upper end of the front surface portion 80. A plurality of insertion holes 8010 are formed at intervals in the width direction in the vertical rising piece 801 on the upper side of the front surface portion 80 of the second member 8.

[0037] [D-5] Case body The case main body 3′ is obtained by connecting the first member 7 and the second member 8. When the upper rising piece 801 of the front surface 80 of the second member 8 is abutted against the hanging piece 721 of the first member 7, the insertion hole 8010 formed in the rising piece 801 of the second member 8 coincides with the insertion hole 722 formed in the hanging piece 721 of the first member 7, and further, these insertion holes 8010, 722 coincide with screw holes 1722 formed at intervals in the width direction of the angle iron 172 on the lower side of the reinforcing member 17 (only the screw holes 1722 at both ends in the width direction are shown in FIG. 12A ). By screwing a screw S3 from the front, the lower end portion of the front surface 72 of the first member 7, the upper end portion of the front surface 80 of the second member 8, and the reinforcing member 17 (angle iron 172) are connected, and the case main body 3′ is obtained.

[0038] In this embodiment, when the hanging piece 721 of the first member 7 and the rising piece 801 of the second member 8 are connected, the rising piece 811 of the side surface portion 81 of the second member 8 is close to the hanging edge 711 of the side surface portion 711 of the first member 7 (left diagram in FIG. 16). In this embodiment, the rising piece 811 of the side surface portion 81 of the second member 8 and the hanging edge 711 of the side surface portion 711 of the first member 7 are not connected.

[0039] The case body 3' is supported by the side panel 9 when slid relative to the side panel 9 from the front. In the case body 3' according to this embodiment, the horizontal piece 810 of the side surface portion 81 of the second member 8, the rising piece 811 of the side surface portion 81 of the second member 8, the hanging edge 711 of the side surface portion 71 of the first member 7, and the rising piece 813 of the side surface portion 81 of the second member 8 form a sliding portion when attaching the case body 3'. When the case body 3' is slid, if the side surface portion 81 of the second member 8 of the case body 3' comes into sliding contact with the side panel 9, the side surface portion 81 can also function as a sliding portion. Furthermore, when the case body 3' is slid, if the horizontal piece 812 of the second member 8 of the case body 3' comes into sliding contact with the side panel 9, the horizontal piece 812 can also function as a sliding portion.

[0040] [D-6] Side plate The side panel 9 is attached to the case support member 6, and the case main body 3' is attached to the case support member 6 and the side panel 9 from the front to form the case 3. As shown in FIG. 14 , the side panel 9 is composed of a vertical main surface portion 90 extending in the front-to-rear direction, an upper horizontal edge 91 at the upper end of the main surface portion 90, an upper vertical edge 92 rising from the upper horizontal edge 91, a lower horizontal edge 93 at the lower end of the main surface portion 90, a lower vertical edge 94 rising from the lower horizontal edge 93, and a narrow rear edge 95 extending from the rear end of the main surface portion 90 in a direction perpendicular to the main surface portion 90. Insertion holes 900 are formed in the rear portion (body side portion) of the main surface portion 90, spaced apart from each other vertically. The insertion holes 900 are holes for attaching the side panel 9 to the case support member 6 with screws S2. The front end of the main surface portion 90 is referred to as the front end 901.

[0041] In the side panel 9 according to this embodiment, the upper horizontal edge 91, the upper vertical edge 92, and the lower vertical edge 94 form a slidable portion when the case body 3' is slidably supported on the side panel 9 from the front. When the case body 3' is slid, if the side surface portion 81 of the second member 8 of the case body 3' comes into sliding contact with the main surface portion 90, the main surface portion 90 can also function as a slidable portion. Furthermore, when the case body 3' is slid, if the horizontal piece 812 of the second member 8 of the case body 3' comes into sliding contact with the lower horizontal edge 93, the lower horizontal edge 93 can also function as a slidable portion.

The case support member 6 has support portions (upper band portion 601 and lower band portion 602) located along the side surfaces of the vertical frame 1, and a front surface portion 67, and the left and right side panels 9 of the case 3 are fixed to the support portions (upper band portion 601 and lower band portion 602) with screws S1. The left and right side surfaces of the case main body 3' (side surface portion 71 of the first member 7 and side surface portion 81 of the second member 8) are supported by the left and right side panels 9, and the front surface of the case main body 3' (front surface portion 80 of the second member 8) is fixed with screws S5 that are screwed into the front surface portion 67 of the case support member 6 from the front. A rising edge 700 at the rear end of the top surface portion 70 of the first member 7 of the case main body 3' is fixed to the frame W with screws S4 that are screwed in from the front.

[0043] [E-2] Overview of case installation method The following describes how to attach the case 3. Here, we assume that the case 3 is fitted in a so-called recessed corner, and that a side wall W2 (Figs. 1 and 5) is present near at least one widthwise end of the case 3. The case body 3' is attached to the frame W and the case support member 6 by sliding the case body 3' from the front relative to the case support member 6 and side panel 9 attached to the vertical frame 1, and the case body 3' is then attached to the frame W and the case support member 6 to form the case 3.

[0044] First, a case support member 6 having support portions (upper band portion 601 and lower band portion 602) and a front surface portion 67 is prepared, and prior to attaching the vertical frame 1 to the skeleton W, the case support member 6 is attached to an upper portion of the side surface of the vertical frame 1. The support portions (upper band portion 601 and lower band portion 602) extend in the front-to-rear direction, facing and spaced apart from the side surface of the vertical frame 1, and the front surface portion 67 is located forward of the vertical frame 1. A side panel 9 having a sliding portion is prepared, and prior to attaching the vertical frame 1 to the skeleton W, the side panel 9 is fixed to the support portions (upper band portion 601 and lower band portion 602) of the case support member 6 fixed to the vertical frame 1. Portions of the side panel 9 form the sliding portion. The vertical frame 1 is attached to the skeleton W with the case support member 6 and side panel 9 attached.

[0045] A case body 3' including left and right side portions (side portion 71, side portion 81) with sliding portions and a front portion (front portion 72, front portion 80) is prepared, and the left and right side portions (side portion 71, side portion 81) of the case body 3' are slid from the front onto the side plate 9 while the case body 3' is supported by the side plate 9, and with the front portion 80 in contact with or close to the front surface portion 67 of the case support member 6, the front portion 80 is fixed to the front surface portion 67 from the front using screws S5. A rising edge 700 at the rear end of the top surface portion 70 of the case body 3' is in contact with the body W, and is fixed to the body W from the front using screws S4.

[0046] [E-3] Installation of case support members to the vertical frame Prior to attaching the vertical frame 1 to the main body W, a case support member 6 is attached to the upper portion of the side of the vertical frame 1. The case support member 6 is fixed to the outer visible surface 42 of the guide rail base frame 4 by abutting the upper vertical edge 62 and the lower vertical edge 64 against the upper portion of the outer visible surface 42 of the guide rail base frame 4 with screws S1 inserted through the insertion holes 620, 640. The state in which the case support member 6 is attached to the side of the vertical frame 1 is shown in Figures 9 and 10.

[0047] 9 and 10, in this embodiment, the plate-like portion 600 of the base 60 of the case support member 6 is positioned so as to substantially cover the outer visible surface 52 of the guide rail 5, and the upper band-like portion 601 and the lower band-like portion 602 of the base 60 face the outer visible surface 42 of the guide rail base frame 4 at a distance. The upper band-like portion 601 and the lower band-like portion 602 of the case support member 6 face the side surface of the vertical frame 1 in a state protruding from the side surface, and form a support portion extending along the side surface, and the side panel 9 is fixed to and supported by the upper band-like portion 601 and the lower band-like portion 602 with screws S2.

[0048] The front side of the plate-like portion 600 of the base 60 of the case support member 6 extends forward beyond the outer visible surface 52 and the visible surface 53 of the guide rail 5, and the front surface 67 is positioned in a protruding manner forward of the visible surface 53. Screw holes 670 are formed at positions above and below the height direction of the front surface 67. The front surface 80 of the second member 8 is fixed and supported by the front surface 67 with screws S5.

[0049] [E-4] Attaching the side panel to the case support member The side panel 9 is attached to the case support member 6 attached to an upper portion of the side portion of the vertical frame 1. The side panel 9 is attached to the case support member 6 before the vertical frame 1, to which the case support member 6 is attached, is attached to the main body W. As shown in the left diagram of FIG. 15 and the right diagram of FIG. 16 , the rear half of the main surface portion 90 of the side panel 9 is positioned so as to cover the upper band-like portion 601 and the lower band-like portion 602 of the base 60, and the side panel 9 is fixed to the upper band-like portion 601 and the lower band-like portion 602 of the base 60 with screws S2 in a state in which the insertion holes 900 formed in the main surface portion 90 of the side panel 9 are aligned with the screw holes 603 of the upper band-like portion 601 and the screw holes 604 of the lower band-like portion 602.

[0050] 15, the rear edge 95 of the side panel 9 is close to the main body W, the rear half of the main surface portion 90 faces the outer visible surface 42 at a distance, the front half of the main surface portion 90 faces the outer visible surface 52 at a distance, and the front surface portion 67 of the case support member 6 is located forward of the front end 901 of the main surface portion 90. As shown in the right diagram of FIG. 16, the main surface portion 90 of the side panel 9 abuts against the upper band-shaped portion 601 and the lower band-shaped portion 602 of the base 60 of the case support member 6 and is connected with screws S2, the upper horizontal edge 91 is located close to above the upper edge 65, the lower horizontal edge 93 is located close to below the lower edge 66, and the lower vertical edge 94 is located close to the side surface (outer visible surfaces 42, 52) of the vertical frame 1.

[0051] [E-5] Connection between the first and second members The case main body 3' is assembled by connecting the second member 8 to the first member 7 from the front. The rising piece 801 on the upper side of the front part 80 of the second member 8 is brought into contact with the hanging piece 721 of the first member 7, and at this time, the insertion hole 8010, the insertion hole 722, and the screw hole 1722 are aligned, and the hanging piece 721 of the first member 7 (and the angle member 172 on the lower side of the reinforcing member 17) and the rising piece 801 of the second member 8 are connected by the screw S3.

[0052] In this embodiment, as shown in the left diagram of Figure 16, when the hanging piece 721 of the first member 7 on the front side and the rising piece 801 of the second member 8 are connected, the rising piece 811 of the side portion 81 of the second member 8 is close to the hanging edge 711 of the side portion 71 of the first member 7.

[0053] [E-6] Installation of the case body In this embodiment, the first member 7 and the second member 8 are connected to assemble the case body 3′ first, and then the case body 3′ is attached by sliding it from the front onto the case support member 6 attached to the upper portion of the side portion of the vertical frame 1 and the side panel 9 attached to the case support member 6. In the case body 3′ according to this embodiment, the horizontal piece 810 of the side portion 81 of the second member 8, the rising piece 811 of the side portion 81 of the second member 8, the hanging edge 711 of the side portion 71 of the first member 7, and the rising piece 813 of the side portion 81 of the second member 8 form a sliding portion when attaching the case body 3′. In the side panel 9 according to this embodiment, the upper horizontal edge 91, the upper vertical edge 92, and the lower vertical edge 94 form a slidable portion when the case body 3′ is slidably supported by the side panel 9 from the front. When the case main body 3' is slid and supported on the side panel 9 fixed to the case support member 6, the upper horizontal edge 91 of the side panel 9 in particular functions as a sliding guide surface on which the upper horizontal piece 810 of the side portion 81 of the second member 8 that forms the case main body 3' is placed or supported. In addition, the upper vertical edge 92 and the lower vertical edge 94 of the side panel 9 also function as guide portions.

[0054] When the case body 3′ slides relative to the side panel 9, first, the hanging edge 711 of the first member 7 of the case body 3′ moves toward the frame along the upper vertical edge 92 of the side panel 9, and when the second member 8 of the case body 3′ moves to the front end of the side panel 9, the upper horizontal piece 810 of the side surface 81 of the second member 8 forming the case body 3′ slides while being supported by the upper horizontal edge 91 of the side panel 9, and the upper vertical edge 92 of the side panel 9 slides while being sandwiched between the gap between the rising piece 811 of the case body 3′ and the hanging edge 711, and the rising piece 813 of the case body 3′ slides while being inserted into the gap between the lower vertical edge 94 of the side panel 9 and the side surface (outer visible surface 52) of the vertical frame 1. When the case body 3′ slides relative to the side panel 9, the side surface 81 of the second member 8 of the case body 3′ is close to or in sliding contact with the main surface 90 of the side panel 9. The horizontal piece 812 of the second member 8 of the case body 3' is close to (separated from) the lower side of the lower horizontal edge 93 of the side panel 9.

[0055] When the case body 3′ is slid toward the rear end relative to the side panel 9 attached to the case support member 6, the rising edge 700 at the rear end of the upper surface portion 70 of the first member 7 forming the case body 3′ abuts against the frame W, and both widthwise end portions of the front surface portion 80 of the second member 8 forming the case body 3′ abut against the front surface portion 67 of the case support member 6. At this time, the side surface portion 81 of the second member 8 of the case body 3′ overlaps and covers the front half of the main surface portion 90 of the side panel 9, and the rear ends of the side surface portion 81 of the second member 8 forming the case body 3′ coincide with the front ends of the upper vertical side 62 and lower vertical side 64 of the case support member 6 and also coincide with the vertical connection line between the guide rail base frame 4 and the guide rail 5.

[0056] 7 is a partial cross-sectional view of the side portion of the case 3 when the case main body 3′ is formed by connecting the side panel 9 to the case main body 3′. An upper horizontal piece 810 of the side surface portion 81 of the second member 8 forming the case main body 3′ is placed on the upper horizontal edge 91 of the side panel 9, and an upper vertical edge 92 of the side panel 9 is sandwiched between the rising piece 811 and the hanging edge 711. The side surface portion 81 of the second member 8 of the case main body 3′ and the main surface portion 90 of the side panel 9 are close to each other, the horizontal piece 812 of the second member 8 of the case main body 3′ is close to (spaced apart from) the lower side of the lower horizontal edge 93 of the side panel 9, and the rising piece 813 of the case main body 3′ is sandwiched between the lower vertical edge 94 of the side panel 9 and the side surface (outer visible surface 52) of the vertical frame 1.

[0057] The rising edge 700 at the rear end of the top surface portion 70 of the first member 7 of the case body 3' is fixed to the frame W from the front with screws S4, and the front surface portion 80 of the second member 8 of the case body 3' is fixed to the front surface portion 67 of the case support member 6 from the front with screws S5 (see FIGS. 15 and 17). The attached state of the case 3 is shown in FIGS. 4 to 6. When the case 3 is assembled, the front portion of the case is formed from the front portion 72 of the first member 7 and the front portion 80 of the second member 8, and in the case main body 3' formed from the first member 7 and the second member 8, the first member 7 and the second member 8 are connected only by a screw S3 screwed in from the front, the upper portion (rising edge 700) of the case main body 3' is fixed to the main body W only by a screw S4 screwed in from the front, and the lower portion (front portion 80) of the front portion of the case main body 3' is fixed to the case support member 6 only by a screw S5 screwed in from the front.

[0058] 15 shows that the case body 3′ assembled by connecting the first member 7 and the second member 8 is attached to the case support member 6 attached to the upper portion of the vertical frame 1 and the side panel 9 attached to the case support member 6. However, before connecting the first member 7 and the second member 8, the first member 7 may be slid while its horizontal edge 710 is supported on the upper end of the upper vertical edge 92 of the side panel 9, the rising edge 700 of the top surface portion 70 of the first member 7 abuts against the body W and fixed with screws S4, the second member 8 may then be slid relative to the side panel 9, the rising piece 801 of the second member 8 abuts against the hanging piece 721 of the first member 7 and connected with screws S3, and the front surface 80 of the second member 8 abuts against the front surface portion 67 of the case support member 6 and connected with screws S5. The order in which the screws S3, S4, and S5 are tightened is not limited. If the site allows screws to be inserted from the side, the side panel 9, the first member 7, and the second member 8 to The formed holes may be used to fasten the plate from the side with screws.

[0059] In this embodiment, the case main body 3' (first member 7, second member 8) of the case 3 is slid from the front to be supported on the side panel 9 and is fixed to the front portion 67 of the case support member 6 with screws S5 attached from the front. Therefore, even if the case 3 is fitted in an inside corner (whether it is a single inside corner or a double inside corner), the case can be easily installed. For example, if one of the left and right sides is fitted in an inside corner and the other is not, the vertical frame 1 may be attached to the frame on the other side before the case support member 6 and side panel 9 are installed. Furthermore, the case installation structure according to this embodiment can be used even if the case is fitted in a corner other than an inside corner.

[0060] In this embodiment, as shown in Fig. 7 , the upper vertical edge 92 of the side panel 9 is sandwiched between the rising piece 811 and the hanging edge 711, and the upper vertical edge 92 prevents the hanging edge 711 from spreading toward the building frame. Alternatively, the rising piece 811 and the hanging edge 711 may be abutted against each other, and the upper vertical edge 92 may be positioned inside the hanging edge 711 (to the right in Fig. 7 ). Furthermore, although the tip of the upper vertical edge 92 is spaced apart from the horizontal edge 710 in the embodiment shown in Fig. 7 , the tip of the upper vertical edge 92 may also abut against the horizontal edge 710.

[0061] [F] Blind shutter maintenance work In the blind shutter according to this embodiment, the link mechanism that operates the slats 20 is provided within the internal space of the guide rail 5, and the gear box 10 including the electric motor M and the control unit 13 are provided near the upper end of the vertical frame 1. Therefore, when performing maintenance on the blind shutter, it is necessary to remove the guide rail 5 from the guide rail base frame 4, and then remove the link mechanism and the gear box 10 including the electric motor M (collectively referred to as the operating mechanism) together with the guide rail 5. In the case 3 of this embodiment, by releasing the connection between the first member 7 and the second member 8 and releasing the connection between the second member 8 and the case support member 6 (specifically, by removing the screw S3 connecting the upper end portion of the front portion 80 of the second member 8 to the lower end portion of the front portion 72 of the first member 7 and removing the screw S5 connecting the front portion 80 of the second member 8 to the front portion 67 of the case support member 6), the second member 8 can be slid forward relative to the first member 7 attached to the main body W and the side panel 9 and case support member 6 fixed to the case support member 6, and the second member 8 can be removed.By removing the second member 8 or sliding it forward a predetermined distance (see distance d in Figure 18), the guide rail 5 on which the operating mechanism is mounted can be removed.

[0062] In the case structure according to this embodiment, when the guide rail 5 equipped with the operating mechanism needs to be removed for maintenance or the like, the maintenance work can be performed with the second member 8 removed or slid forward to a predetermined position. Furthermore, even at a site where a finishing wall W1 is further provided on the skeleton W, during maintenance, the upper end portion of the guide rail 5 equipped with the operating mechanism can be removed from the lower portion of the case 3 by sliding only the second member 8 forward.
