DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] [A] Overview of Blind Shutter An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view and a side view of a blind shutter according to this embodiment, FIG. 2 is a vertical cross-sectional view of the blind shutter according to this embodiment, FIG. 3 is a horizontal cross-sectional view of the blind shutter according to this embodiment (showing the horizontal cross-sections at different height positions on the left and right), and FIG. 4 is an exploded perspective view of the blind shutter. The 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 provided in a protruding manner from a framework W located outside the widthwise ends of the window opening, and a drip edge 16 is provided below the window opening between the left and right vertical frames 1, and 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 attached in a protruding manner from the framework W above the opening. In addition, 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 body W and a guide rail 5 connected to the guide rail base frame 4. The shutter curtain 2 is composed of a plurality of slats 6 extending between the left and right guide rails 5, and the plurality of slats 6 are liftable and tiltable, and function as blinds. The case 3 is composed of a first member 7 located above the window opening and fixed to the body W, and a second member 8 connected to the first member 7, and the first member 7 and the second member 8 are steel plates. Case support members 9A and 9B used to attach the case 3 to the vertical frame 1 are provided at the upper part of the outer surface of the vertical frame 1 (guide rail base frame 4). Details of these elements will be described later.

[0017] Link mechanisms (not shown) for raising, lowering and tilting the multiple slats 6 are located in 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 gear box 10 located in the case 3. Rotating shafts at the upper ends of the left and right link mechanisms are synchronized by a shaft 11 (see FIG. 4) located in the case 3. A shaft spring 11a is provided on one end side of the shaft 11. Located in the case 3, a receiver unit 12 (attached to the body W) for receiving an opening / closing signal and a control unit 13 for controlling the electric motor M based on the signal received by the receiver unit 12 are provided. In this embodiment, the drive mechanism including the electric motor M and the gear box 10 and the control unit 13 (fixed to the gear box 10 in this embodiment) are provided at the upper end of the guide rails 5 and are not attached to the case 3. In this embodiment, the control unit 13 is covered on the outdoor side and the bottom side by a cover 13A fixed to the guide rail base frame 4, and prevents water droplets from splashing on the control unit 13 due to rainwater blowing in from below the case 3. An inner lintel (case bottom surface) 14 is provided on the lower body side of the case 3, and a back plate 15, which is the rear surface of the case 3, is provided on the body W. Please note that in this embodiment, there are multiple modes in which the height position of the inner lintel 14 in the case 3 is different (see Figures 2 and 17). In this embodiment, the upper end of the back plate 15 is located slightly above the upper end of the vertical frame 1, and the 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 body W by 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. The blind shutter itself is known, and Patent Documents 1 to 4 can be appropriately referred to for the operating mechanism (including the link mechanism and drive mechanism) and basic operation of the shutter (slats 6).

[0018] [B] Vertical frame A detailed description will be given of the vertical frame 1 consisting of the guide rail base frame 4 and the guide rail 5. 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 projected side 41 and an outer projected side 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 projected side 41 and the outer projected side 42 to which the guide rail 5 is connected (see FIG. 13(A)).

[0019] The guide rail 5 is a long member extending in the height direction, and includes a base side 50 on the rear end side, an inner projected side 51 extending parallel to the base side 50 in a direction away from the body W (guide rail base frame 4), an outer projected side 52, and a face 53 connecting the tips of the inner projected side 51 and the outer projected side 52. The base side 50 is formed with connecting pieces 500 and 501 that are connected to the connecting pieces 410 and 420 of the guide rail base frame 4. The inner projected side 51 of the guide rail 5 is provided with a guide groove 510 extending in the height direction (see Fig. 2 and Fig. 13(A)). In addition, a concealing fin 511 is formed on the rear end side of the inner projected side 51 of the guide rail 5 in the face direction, and when viewed from the front, it is designed to hide the gap between the window sash WS and the inner projected side 41 of the guide rail base frame 4 (Fig. 3 and Fig. 13(A)).

[0020] In this embodiment, the guide rail base frame 4 is fixed to the frame W with a screw S5, and the guide rail 5 is detachably connected to the guide rail base frame 4 with a screw S6. The inner projected side 41 of the guide rail base frame 4 and the inner projected side 51 of the guide rail 5 form the inner projected surface of the vertical frame 1, and the outer projected side 42 of the guide rail base frame 4 and the outer projected side 52 of the guide rail 5 are flush with each other to form the outer projected 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 with each other, and the connecting piece 410 of the guide rail base frame 4 and the connecting piece 500 of the guide rail 5 are fixed with the screw S6 in an overlapping state. Therefore, when the blind shutter is installed, the connection of the guide rail 5 to the guide rail base frame 4 can be released by removing the multiple screws S6 provided in the height direction, and the guide rail 5 can be detached from the vertical frame 1.

[0021] [C] Shutter Curtain The shutter curtain 2 is composed of multiple slats 6 extending between the left and right guide rails 5, and when the multiple slats 6 are in a vertical position and cover the opening, the opening is fully closed, and when the opening is fully closed, the inclination of each slat 6 can be changed, making it possible to control the amount of light and visibility. Also, the opening can be opened by raising all the slats 6.

[0022] Both longitudinal ends of each slat 6 are connected to slat supports 60 located outside a guide groove 510 formed in the height direction on the inner projected edge 51 of the guide rail 5 and protruding from the projected surface. The slat supports 60 are connected to a link mechanism (not shown) constituting a lifting mechanism and a tilt 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 gear box 10. For details of the link mechanism and the drive mechanism, refer to Patent Documents 1 to 4.

[0023] By operating the link mechanism (lifting mechanism), the slat support 60 rises, causing the slats 6 supported by the slat support 60 to rise, and by lowering the slat support 60, causing the slats 6 supported by the slat support 60 to lower. When the opening is fully opened, all the slats 6 rise to open the opening, and these slats 6 are stored in the case 3 in a substantially horizontal position, overlapping each other. When the opening is fully closed, the lowest slat 6 (bottom slat 6) abuts or is close to the drip edge 16 (see FIG. 2). Furthermore, by operating the link mechanism (tilt mechanism), the slat support 60 tilts, causing the slats 6 supported by the slat support 60 to tilt.

[0024] In this embodiment, a cushioning rubber is provided at the upper end of each slat 6 and at the upper and lower ends of the bottom slat 6, extending in the length direction, and when the opening is fully closed, two protrusions of the cushioning rubber come into contact with the adjacent slats 6, and the cushioning rubber at the lower end of the bottom slat 6 comes into contact with the drip edge 16, thereby reducing light leakage. In addition, the height dimension of the slats 6 is slightly smaller than the projected dimension of the guide rail 5, so that when the slats 6 are in a horizontal position, they fit within the projected surface of the guide rail 5 (Fig. 2).

[0025] [D] First and second components constituting the case The first member 7 and the second member 8 which are components of the case 3 will now be described. As shown in Figs. 8 to 10, the first member 7 has an upper surface portion 70, left and right first side surface portions 71 extending downward from both ends in the width direction of the upper surface portion 70, and an upper front surface portion 72 extending downward from the front end of the upper surface portion 70. A lateral recessed groove 73 extending horizontally in the front-rear direction is formed in the first side surface portions 71. The recessed groove 73 is formed by a horizontal lower surface 730, a vertical bottom surface 731, and a horizontal upper surface 732.

[0026] The first side surface portion 71 is composed of a first portion 710 located above the groove 73, a second portion 711 located below the groove 73, and the groove 73. The height of the front end of the first portion 710 matches the height dimension of the upper front surface portion 72, and both ends of the upper front surface portion 72 in the width direction are continuous with the front ends of the left and right first portions 710. The lower side of the upper front surface portion 72, i.e., the front of the left and right second portions 711, are open.

[0027] As shown in Fig. 9, a horizontal piece 712 extending toward the other first side surface portion 71 and a rising piece 713 rising from the tip of the horizontal piece 712 are integrally formed at the lower end of the first side surface portion 71, i.e., the lower end of the second portion 711. As shown in Fig. 10, the upper surface portion 70 is gently inclined downward toward the front, and a vertical rising piece 700 is integrally formed on the base end side. 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 upper front portion 72. As shown in Fig. 9, insertion holes 722 are formed at both ends of the hanging piece 721 in the width direction.

[0028] As shown in Fig. 10, the rear side of the second portion 711 on the lower side of the first side surface portion 71 has an upper insertion hole 74a and a lower insertion hole 74b, and an upper insertion hole 75a and a lower insertion hole 75b are formed at positions spaced apart from the front of the insertion holes 74a and 74b. The rear part of the first side surface portion 71 is connected to the rear end parts of the upper case support member 9A and the lower case support member 9B by screws S2 at the insertion holes 74a and 74b. With the insertion holes 75a and 75b aligned with the insertion holes 83a and 83b (described later) of the second side surface portion 81 of the second member 8, the overlapping part of the first side surface portion 71 and the second side surface portion 81 is connected to the front end parts of the upper case support member 9A and the lower case support member 9B by screws S2.

[0029] An upper temporary fixing hole 76a and a lower temporary fixing hole 76b are formed in the first side surface portion 71 at positions spaced further forward from the upper insertion hole 75a and the lower insertion hole 75b. The diameters of the temporary fixing holes 76a and 76b are slightly smaller than the diameters of the insertion holes 74a and 74b, the insertion holes 75a, the insertion holes 75b, and the insertion holes 83a and 83b, and while the insertion holes 74a and 74b, the insertion holes 75a, the insertion holes 75b, and the insertion holes 83a and 83b are adapted to insert the shafts of the screws S2, the temporary fixing hole 76a and the lower temporary fixing hole 76b are adapted to temporarily fix the shafts of the screws S2 (even if the female threads are not cut).

[0030] The first member 7 according to this embodiment is configured by assembling three elements: an upper element consisting of a top surface portion 70, first portions 710 of the left and right first side surface portions 71, and an upper front portion 72; and two lower elements consisting of second portions 711 of the left and right first side surface portions 71. A connecting piece consisting of a horizontal piece and a vertical piece hanging down from the horizontal piece is formed at the lower end of the left and right first portions 710 of the upper element, and a connecting piece consisting of a horizontal piece and a vertical piece rising from the horizontal piece is formed at the upper end of the second portion 711 which is the lower element. The vertical piece of the connecting piece of the first portion 710 and the vertical piece of the connecting piece of the second portion 711 are overlapped and connected with a rivet R, and the horizontal piece of the connecting piece of the second portion 711 is the lower surface 730 of the groove 73, the horizontal piece of the connecting piece of the first portion 710 is the upper surface 732 of the groove 73, and the overlapped vertical pieces are the bottom surface 731 of the groove 73. The number of plates constituting the first member 7 is not limited, and the first member 7 may be formed from, for example, one plate.

[0031] The first member 7 according to this embodiment is reinforced by a reinforcing member 17. As shown in Fig. 12, 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 across the left and right brackets 170, and a lower angle member 172.

[0032] The left and right brackets 170 have trapezoidal side portions 1700 corresponding to the shape of the first parts 710 of the first side portions 71 of the first member 7, rear pieces 1701 at the rear ends of the side portions 1700, front surfaces 1702 at the front ends of the side portions 1700, and upper pieces 1703 on the upper edges of the side portions 1700.

[0033] A horizontal piece 1720 extending rearward and a vertical piece 1721 hanging down from the tip (rear end) of the horizontal piece 1720 are integrally formed at the lower end of the lower angle iron 172, the horizontal piece 1720 being located at the same height as the lower ends of the left and right brackets 170, and the vertical piece 1721 being located 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. Screw holes 1722 are formed at both widthwise end portions of the vertical piece 1721 of the lower angle iron 172.

[0034] The reinforcing member 17 is fixed to the main body W with screws S4, with the upper portions of the rear pieces 1701 of the left and right brackets 170 overlapping both widthwise end portions of the raised pieces 700 at the base end of the upper surface portion 70 of the first member 7, and the upper pieces 1703 of the left and right brackets 170 are fixed to the undersides of both widthwise end portions of the upper surface portion 70 of the first member 7 with rivets R, and the side portions 1700 of the left and right brackets 170 abut or are close to the inner surface of the first part 710 of the first member 7, and the front surfaces 1702 and angle irons 171, 172 of the left and right brackets 170 abut or are close to the inner surface of the upper front portion 72 of the first member 7, so that the reinforcing member 17 is located in the internal space of the upper element of the first member 7.

[0035] 8 and 11, the second member 8 has a front portion 80 and left and right second side portions 81 extending rearward from both ends in the width direction of the front portion 80. The front portion 80 and the second side portions 81 have the same height dimension, which is approximately the same as the height dimension of the second portion 711 of the first side portion 71 of the first member 7.

[0036] 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 portion 80. Insertion holes 8010 are formed at both ends in the width direction of the vertical rising piece 801 on the upper side of the front portion 80 of the second member 8. A horizontal piece 802 extending rearward and a rising piece 803 rising from the tip (rear end) of the horizontal piece 802 are integrally formed at the lower end of the front portion 80.

[0037] A horizontal piece 810 extending toward the other second side surface portion 81 and a rising piece 811 rising from the tip of the horizontal piece 810 are integrally formed at the upper end of the second side surface portion 81. A round hole 8110 is formed at a predetermined position of the rising piece 811 (approximately the middle position in the illustrated embodiment). The diameter of the round hole 8110 is slightly larger than the diameter of the rivet R connecting the upper element and the lower element of the first member 7. A horizontal piece 812 extending toward the other second side surface portion 81 and a rising piece 813 rising from the tip of the horizontal piece 812 are integrally formed at the lower end of the second side surface portion 81.

[0038] The ends of the upper horizontal piece 800 of the front portion 80 and the upper horizontal pieces 810 of the left and right second side portions 81 are close to or abutting, and the ends of the upper rising piece 801 of the front portion 80 and the rising pieces 811 of the left and right second side portions 81 are close to or abutting, and a step-shaped connecting portion is formed at the upper end of the second member 8.

As shown in the right diagram of Figure 11, the visible width dimension of the upper rising piece 801 of the front portion 80 is longer than the visible width dimension of the lower rising piece 803, and the visible width dimension of the upper horizontal piece 810 of the second side surface portions 81 is smaller than the visible width dimension of the lower horizontal piece 812 of the second side surface portion 81.

[0040] As shown in Fig. 8, the case 3 is assembled by connecting the second member 8 to the first member 7 by sliding it from the front. The second member 8 is connected to the first member 7 with the left and right second side surface portions 81 at least partially overlapping the left and right first side surface portions 71 of the first member 7 to form the case 3 and is integrated with the first member 7, and the second member 8 is slidable forward relative to the first member 7 when it is released from its connection with the first member 7 (see Fig. 16).

[0041] [E] Case support member The case support members 9A and 9B used to attach the case 3 are formed from a common case support member 9, and are attached to the guide rail base frame 4 with their postures (directions) changed. As shown in Figs. 13 and 14, the case support members 9A and 9B are long pieces that extend horizontally in the front-rear direction while being fixed to the upper portion of the outer surface of the outer projected edge 42 of the guide rail base frame 4. As shown in Fig. 15, the case support member 9 is composed of a vertically extending base 90, a rising piece (middle piece) 91 that extends horizontally so as to rise from the vertical base 90, and a vertical piece 92 that extends vertically from the tip of the rising piece 91. In this embodiment, the base 90 is shorter in the front-rear direction (projection direction) than the rising piece 91 and the vertical piece 92, but is not limited to this. In this embodiment, the vertical piece 92 of the case support member 9 functions as a connecting guide piece when the first member 7 and the second member 8 are positioned and fixed, and also functions as a guide support piece when the first member 7 is slid.

[0042] Two insertion holes 900 are formed in the base 90 of the case support member 9 with an interval in the length direction (front-rear direction), and the case support member 9 is fixed to the outer projected edge 42 of the guide rail base frame 4 by abutting the base 90 against an upper portion of the outer projected edge 42 of the guide rail base frame 4 with a screw S1 that passes through the insertion hole 900. The upper case support member 9A is fixed in an orientation such that the vertical piece 92 rises vertically from the horizontal rising piece 91, and the vertical piece 92 is a rising piece. The lower case support member 9B is fixed in an orientation such that the vertical piece 92 falls vertically down from the horizontal rising piece 91, and the vertical piece 92 is a falling piece.

[0043] The vertical piece 92 serving as a connecting guide piece for the case support member 9 has two screw holes 920 formed therein spaced apart in the longitudinal direction (front-to-back or forward direction), with the rear screw hole 920 receiving a screw S2 that connects the first side portion 71 of the first member 7 of the case 3 to the case support member 9, and the front screw hole 920 receiving a screw S2 that connects the first side portion 71 of the case 3 and the second side portion 81 of the second member 8 to the case support member 9.

[0044] As shown in FIG. 13, in this embodiment, the front end portions of the upper case support member 9A and the lower case support member 9B extend beyond the outer projected surface (outer projected edge 42) of the guide rail base frame 4 to the outer projected surface (outer projected edge 52) of the guide rail 5, and a front screw hole 920 is formed in the front end portion facing the outer projected surface (outer projected edge 52) of the guide rail 5 at a distance. In this embodiment, the fixing member 18 of the limit switch is provided in the upper portion of the outer projected edge 52 of the guide rail 5. The rising dimension of the rising piece 91 of the case support member 9 (the protruding dimension from the outer projected surface of the vertical frame 1) is larger than the protruding dimension of the fixing member 18 from the outer projected edge 52 of the guide rail 5, and the fixing member 18 does not interfere with the attachment of the case 3 to the upper case support member 9A and the lower case support member 9B.

[0045] [F] Case assembly structure and assembly The assembly structure and assembly of the case 3 will be described in detail. The lower surfaces 730 of the recessed grooves 73 of the left and right first side surface portions 71 of the first member 7 form a slide support portion, and horizontal pieces 810 at the upper ends of the left and right second side surface portions 81 of the second member 8 are placed or supported on the lower surfaces 730 to form a sliding portion that slides. In this embodiment, the slide support portion includes the bottom surfaces 731 of the recessed grooves 73 and an upper portion of the second portion 711 of the first side surface portion 71, and the slide portion may include the rising pieces 811 at the upper ends of the left and right second side surface portions 81 of the second member 8 and an upper portion of the second side surface portion 81 of the second member 8.

[0046] The second member 8 is capable of sliding in the front-to-rear direction relative to the first member 7 with the horizontal piece (sliding piece, sliding portion) 810 resting on the underside (slide support portion) 730, the raised piece 811 being close to or in sliding contact with the bottom surface 731 of the groove 73, the inner surface of the second side portion 81 being close to or in sliding contact with the outer surface of the first side portion 71, the horizontal piece 812 on the lower side of the second side portion 81 being close to or in sliding contact with the horizontal piece 712 on the lower side of the first side portion 71, and the vertical piece 713 on the lower side of the second side portion 81 being close to or in sliding contact with the vertical raised piece 813 on the lower side of the first side portion 7.

[0047] When the second member 8 is slid toward the rear end of the first member 7 relative to the first member 7, the vertical rising piece 801 at the upper end of the front portion 80 of the second member 8 abuts against the hanging piece 721 at the lower end of the upper front portion 72 of the first member 7 in a state in which the second side portion 81 of the second member 8 partially overlaps the outer surface of the second part 711 of the first side portion 71 of the first member 7, and at this time, the insertion holes 83a, 83b of the second side portion 81 of the second member 8 coincide with the front insertion holes 75a, 75b of the first side portion 71 of the first member 7. In this positional relationship, the case 3 is formed by connecting the second member 8 to the first member 7. Also, the rivet R located at the front side is adapted to fit into the round hole 8110 formed in the rising piece 811 on the upper side of the second side portion 81 of the second member 8 (see FIG. 5).

[0048] An insertion hole 8010 formed in the upper vertical rising piece 801 of the front part 80 of the second member 8 coincides with an insertion hole 722 formed in the lower hanging piece 721 of the upper front part 72 of the first member 7, and further, these insertion holes 8010, 722 coincide with screw holes 1722 formed at both ends in the width direction of the lower angle member 172 of the reinforcing member 17. By attaching a screw S3 from the front, the lower end portion of the upper front part 72 of the first member 7, the upper end portion of the front part 80 of the second member 8, and the reinforcing member 17 (angle member 172) are connected. In this embodiment, the first side surface part 71 of the first member 7 and the second side surface part 81 of the second member 8 are connected by a screw S2 that attaches the first member 7 and the second member 8 to the case support members 9A and 9B.

[0049] The assembled state of the case is shown in Fig. 5 and Fig. 8. In the state where the case 3 is assembled from the first member 7 and the second member 8, the case front part is formed from the upper front part 72 of the first member 7 and the front part 80 of the second member 8, and the case front part has a recess 30 extending horizontally in the width direction. The case side part is formed from the first part 710 on the upper side of the first side part 71 of the first member 7, the rear part of the second part 711 on the lower side of the first side part 71 of the first member 7, and the second side part 81 of the second member 8 overlapping with the front part of the second part 711 on the lower side of the first side part 71 of the first member 7, and the case side part has a recess 31 extending horizontally in the projection direction. The recess 30 in the case front part and the recess 31 in the case side part are continuous, resulting in a neat appearance.

[0050] [G] Case mounting structure and installation The mounting structure and mounting of the case 3 to the vertical frame 1 will be described. The case side portions of the case 3 (first member 7, second member 8) are mounted from the front to an upper case support member 9A and a lower case support member 9B that are mounted to an upper portion of the guide rail base frame 4. The case 3 is slidable along the upper case support member 9A and the lower case support member 9B when placed on the upper case support member 9A, and the left and right case side portions are fixed to the upper case support member 9A and the lower case support member 9B when slid to predetermined positions relative to the upper case support member 9A and the lower case support member 9B (see Fig. 14 and Figs. 5 to 7).

[0051] The upper case support member 9A has a support portion (vertical piece 92 as a guide support piece) located away from the outer prospective surface of the vertical frame (guide rail base frame 4) 1, and the case side portion has an upper slide portion that is placed on the vertical piece 92 as a guide support piece and can slide. As shown in FIG. 6, the lower surface 730 of the recessed groove 73 of the first member 7 is placed on the upper end 920A of the vertical piece 92 of the upper case support member 9A, and the inner surface of the upper part of the second part 711 of the first side part 71 of the first member 7 is close to or in sliding contact with the outer surface of the vertical piece 92. That is, the upper slide portion of the case side portion has a first part (lower surface 730) slidably placed on the upper end 920A of the vertical piece 92 as a guide support piece, and a second part (upper part of the second part 711 of the first side part 71) that is in sliding contact or close to the outer surface of the vertical piece 92 as a guide support piece.

[0052] The lower case support member 9B has a support portion (vertical piece 92 as a guide support piece) located away from the outer prospective surface of the vertical frame (guide rail base frame 4) 1, and the case side portion has a lower slide portion that can slide along the vertical piece 92 as a guide support piece. As shown in FIG. 7, the lower end 920B of the vertical piece 92 of the lower case support member 9B is close to the horizontal piece 712 at the lower end of the first side portion 71 of the first member 7, and the inner surface of the lower part of the second part 711 of the first side portion 71 of the first member 7 is close to or in sliding contact with the outer surface of the vertical piece 92 as a guide support piece. That is, the lower slide portion of the case side portion has a first part (horizontal piece 712) that is in sliding contact or close to the lower end 920B of the vertical piece 92 as a guide support piece, and a second part (lower part of the second part 711 of the first side portion 71) that is in sliding contact or close to the outer surface of the vertical piece 92 as a guide support piece.

[0053] The case 3 is slidable along the upper case support member 9A and the lower case support member 9B while being placed on the upper case support member 9A. At this time, since the case 3 is placed on the upper case support member 9A, the weight of the case 3 is supported by the upper case support member 9A. By providing the lower case support member 9B, the case 3 is less likely to tip forward (when the front end portion of the case 3 drops downward, the horizontal piece 712 abuts against the lower end 920B of the vertical piece 92 serving as a guide support piece of the lower case support member 9B). This prevents the case 3 from slipping off, improving the ease of installation. As a result of the improved ease of installation of the case 3, installation can be done by one person. Furthermore, by providing the lower case support member 9B, the strength of the case 3 against the upward blowing load is also improved.

[0054] The case 3 is slid toward the body relative to the upper and lower case support members 9A and 9B, and the insertion hole 83a of the second side surface portion 81 of the second member 8 and the insertion hole 75a of the first side surface portion 71 of the first member 7 are aligned with the front screw hole 920 of the upper case support member 9A and fixed with the screw S2, and the insertion hole 83b of the second side surface portion 81 of the second member 8 and the insertion hole 75b of the first side surface portion 71 of the first member 7 are aligned with the front screw hole 920 of the lower case support member 9B and fixed with the screw S2. At the same time as the case 3 is attached to the upper case support member 9A and the lower case support member 9B with the screw S2, the second side surface portion 81 of the second member 8 and the first side surface portion 71 of the first member 7 are connected. The insertion hole 74a on the rear end side of the first side surface portion 71 of the first member 7 is aligned with the screw hole 920 on the rear side of the upper case support member 9A and fixed with the screw S2, and the insertion hole 74b on the rear end side of the first side surface portion 71 of the first member 7 is aligned with the screw hole 920 on the rear side of the lower case support member 9B and fixed with the screw S2. In this embodiment, the positioning of the case 3 is automatically performed by aligning the insertion holes 75a, 75b, 83a, 83b, 74a, 74b on the case 3 side with the screw holes 920 formed in the upper and lower case support members 9A and 9B at a distance from each other in the front and rear, improving the ease of installation of the case 3.

[0055] FIG. 14 shows that the case 3 assembled by connecting the first member 7 and the second member 8 is attached to an upper case support member 9A and a lower case support member 9B at the upper portion of the vertical frame 1; however, when attaching the case 3 using the case support members 9, the rear portion of the first member 7 may be attached to the rear portions of the case support members 9A and 9B, and then the second member 8 may be attached to the front portion of the first member 7 and the front portions of the case support members 9A and 9B.

[0056] [H] Blind shutter maintenance work In the blind shutter according to this embodiment, the link mechanism for operating the slats 6 is provided in the internal space of the guide rail 5, and the drive mechanism 10 including the electric motor M and the control unit 13 are provided at 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 remove the drive mechanism 10 including the link mechanism and the electric motor M (collectively referred to as the operating mechanism) together with the guide rail 5. In the case 3 according to this embodiment, by releasing the connection between the first member 7 and the second member 8, the second member 8 can be slid forward relative to the first member 7 attached to the body W, and the second member 8 can be temporarily fixed in a state where it has been slid forward a predetermined distance. With the second member 8 temporarily fixed, the guide rail 5 on which the operating mechanism is mounted can be removed.

[0057] More specifically, 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 upper front portion 72 of the first member 7 is removed, and the screw S2 connecting the second side portion 81 of the second member 8 to the second portion 711 of the first side portion 71 of the first member 7 is removed. In this state, the second member 8 is able to slide forward relative to the first member 7.

[0058] As shown in Fig. 16, the second member 8 is slid so that the insertion holes 83a, 83b of the second side surface portion 81 of the second member 8 are aligned with the temporary fixing holes 76a, 76b formed in the second portion 711 of the first side surface portion 71 of the first member 7, and the removed screws S2 are inserted from the insertion holes 83a, 83b into the temporary fixing holes 76a, 76b, thereby temporarily fixing the second member 8 at the position where it has been slid forward. The sliding distance d of the second member 8 is shown in Fig. 17. This distance d is determined by the horizontal distance between the insertion holes 75a, 75b and the temporary fixing holes 76a, 76b.

[0059] At this time, a space of expected dimension D (see FIG. 16) is formed between the guide rail base frame 4 and the lower end portion of the front portion 80 of the second member 8 in the lower portion of the case 3. As shown in FIG. 17, this space has a dimension that allows the upper end portion of the guide rail 5 on which the operating mechanism is mounted to be removed from the lower portion of the case 3.

[0060] In the case structure according to this embodiment, when the guide rail 5 on which the operating mechanism is mounted is removed during maintenance or the like, the second member 8 can be temporarily fixed in a state where it has been slid to the temporary fixing position (a position where the insertion holes 83a, 83b and the temporary fixing holes 76a, 76b are aligned), and there is no need to determine the sliding distance of the second member 8 each time. Furthermore, since maintenance work can be performed in a state where the second member 8 is temporarily fixed in the temporary fixing position where it has been slid forward, there is no need to temporarily place the removed case, no space is required for temporary placement, and further, accidents such as inadvertent damage to the temporarily placed case can be prevented. In the case structure of this embodiment, the case 3 is formed by connecting a second member 8 to a first member 7 fixed to the main body W, and the connection of the second member 8 to the first member 7 is released to allow the second member 8 to slide forward relative to the first member 7. Therefore, even at a site where a finishing wall W1 is further provided on the main body W, during maintenance, the guide rail 5 on which the operating mechanism is mounted can be removed from the lower portion of the case 3 by sliding only the second member 8 forward.
