[0009] [Configuration of this embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 to 3, a shutter 1 according to this embodiment is attached to the framework of a building and is arranged so as to be able to open and close an opening in the building. The shutter 1 includes a frame 2 and a shutter main body 4 attached to the frame 2 so as to be able to wind up and extend slats 3. In the following description, the left-right direction of the shutter 1 is defined as the X-axis direction, the up-down direction of the shutter 1 is defined as the Y-axis direction, and the front-rear direction (projection direction) of the shutter 1 is defined as the Z-axis direction. The X, Y, and Z axis directions are perpendicular to each other.

[0010] The frame body 2 comprises left and right vertical frames 21, a top plate 22 screwed to the upper ends of the left and right vertical frames 21, an inspection plate 23 hung on the outer edge of the top plate 22, an upper frame 25 (lintel) attached to the upper part of the left and right vertical frames 21 and below the top plate 22, and a lower frame 26 attached to the lower ends of the left and right vertical frames 21. Guide rails 211 that guide the left and right ends of the slats 3 up and down are attached along the Y-axis direction to the left and right vertical frames 21. An engagement groove (not shown) is formed in the outer edge of the top plate 22 along the X-axis direction, and the inspection plate 23 is attached by having its upper edge hooked into the engagement groove along the X-axis direction of the top plate 22 and the left and right ends of its lower edge screwed to mounting pieces 473 of the case side plates 47 described later, and the inspection plate 23 can be removed from the frame body 2 by unscrewing the mounting pieces 473 of the inspection plate 23. The frame body 2 forms the storage section 20 in which the shutter main body 4 is disposed by the upper parts of the left and right vertical frames 21, the top plate 22, and the upper frame 25, and the storage section 20 can be opened and closed from the front side (outside the room) by attaching and detaching the inspection plate 23. A back plate 5 (see FIG. 5) to which a case side plate 47 described later is attached is attached to the upper parts of the left and right vertical frames 21 that divide the storage section 20. The back plate 5 has extension pieces 51 that extend inward in the X-axis direction from its upper and lower edges, and the extension pieces 51 have case mounting pieces 52 whose front sides are bent up and down. The case side plates 47 are detachably fixed to the case mounting pieces 52 by screws from the front.

[0011] The shutter main body 4 includes a shutter curtain 41 composed of a plurality of connected slats 3, a shutter winding shaft 42 along the X-axis direction capable of winding up and unwinding the shutter curtain 41, a tubular motor (not shown) that drives the shutter winding shaft 42, and a shutter case 45 that supports the shutter winding shaft 42. The tubular motor is built into the shutter winding shaft 42. The operation of the tubular motor is controlled by a control section (not shown), and a communication section 49 (communication unit) shown in FIG. 3 is connected to this control section by wiring 6. Note that if the shutter 1 is not an electrically operated type but a manual type, the configurations such as the tubular motor, control section, and communication section 49 described above are omitted. The shutter curtain 41 is configured by connecting the above-mentioned multiple slats 3 to each other so that they can rotate freely, and the uppermost slat among the multiple slats 3 is attached to the shutter winding shaft 42, and the lowermost slat is attached to a seat plate that sits on the lower frame 26. Therefore, the shutter curtain 41 moves up and down in the Y-axis direction while being guided by the guide rail 211 by the rotation of the shutter winding shaft 42. The shutter case 45 comprises a case back plate 46 aligned along the X-axis direction in which a wiring port 461 through which the wiring 6 is inserted is formed, and a pair of left and right case side plates 47 fixed to and protruding forward from both left and right edges of the case back plate 46. A resin side cap 7 is attached to the case side plates 47 and positioned forward relative to the upper part of the vertical frame 21 in the Z-axis direction, covering the side of the shutter body 4.

[0012] 2 to 4, the case side plate 47 has a side plate main body 471 that rotatably supports one end of the shutter winding shaft 42, a pair of upper and lower mounting pieces 472 that are detachably screwed from the front to the case mounting piece 52 of the back plate 5, a mounting piece 473 to which the left and right ends of the lower edge of the inspection plate 23 are detachably screwed, and a pair of upper and lower cap mounting pieces 474 to which the side caps 7 are screwed. The cap mounting pieces 474 are located forward of the mounting pieces 472. The side plate body 471 is flat, and its front part is arranged to protrude forward in the Z-axis direction from the vertical frame 21 (see Figs. 3 and 6). A rectangular hole 471A is formed in the approximate center of the side plate body 471, in which a bearing member 475 to which the shutter winding shaft 42 is rotatably connected is arranged, and the hole 471A is formed obliquely with respect to the Y-axis direction. A wiring port 471B through which the wiring 6 is passed is formed in the rear upper part of the side plate body 471 in the Z-axis direction. Here, a communication unit 49 that receives an operation signal to enable remote operation of the shutter body 4 is attached to the outer surface side of the side plate body 471 (see Figs. 1 and 3), and the wiring 6 from the shutter winding shaft 42 side is connected to the communication unit 49 through the hole 471A, and the wiring 6 connected to other devices from the communication unit 49 extends to the space on the indoor side of the shutter 1 through the wiring ports 471B and 461. A guide portion 478 is formed at the front lower portion of the side plate main body 471 to guide the edge of the slat 3 in the X-axis direction and suppress lateral displacement in the X-axis direction.

[0013] The bearing member 475 has a generally U-shaped shaft connecting portion 476 having a bottom portion 476A and a pair of side portions 476B, and three fixing portions 477 bent outward from the shaft connecting portion 476. The bottom portion 476A and the pair of side portions 476B of the shaft connecting portion 476 are disposed opposite to the edge portion defining the hole 471A with some clearance therebetween, and the bottom portion 476A is disposed below the pair of side portions 476B. Therefore, the generally U-shaped shaft connecting portion 476 is disposed obliquely with respect to the Z-axis direction. The fixing portions 477 are formed by bending from each of the bottom portion 476A and the pair of side portions 476B, and are fixed to the side plate main body 471 by riveting.

[0014] In this embodiment, the guide portion 478 is formed by machining the side plate main body 471 into a rectangular convex shape, but the guide portion 478 may be formed by attaching a separate member to the side plate main body 471.

[0015] The mounting pieces 472, 473 and the cap mounting piece 474 extend outward in the X-axis direction toward the vertical frame 21. The mounting piece 472 extends outward in the X-axis direction from the upper and lower edges of the side plate body 471 and is configured along the Y-axis direction so as to be oriented to be screwed from the front side in the Z-axis direction. The mounting piece 473 extends outward in the X-axis direction from the lower edge of the side plate body 471 and is configured along the Z-axis direction so as to be screwed from the lower side in the Y-axis direction. The lower cap mounting piece 474 extends from the lower front edge of the side plate body 471 and is configured along the Y-axis direction so as to be screwed from the front side in the Z-axis direction, and the upper cap mounting piece 474 extends from the upper front edge of the side plate body 471 so as to be screwed from the front side in the Z-axis direction. In addition, the upper front edge of the side panel main body 471 is inclined toward the rear (inside the room) in the Y-axis direction more than the lower front edge, and therefore the upper cap mounting piece 474 is inclined in the same manner as the upper front edge of the side panel main body 471. The outward extension dimension in the X-axis direction of the mounting pieces 472, 473 and the cap mounting piece 474 is set corresponding to the left-right dimension in the X-axis direction of the slat 3. For example, if the slat 3 has a large left-right dimension, a case side plate 47 constituting the mounting pieces 472, 473 and the cap mounting piece 474 with an extension dimension that is correspondingly smaller is selected, and, for example, if the slat 3 has a small left-right dimension, a case side plate 47 constituting the mounting pieces 472, 473 and the cap mounting piece 474 with an extension dimension that is correspondingly larger is selected.

[0016] The above-described shutter is assembled as follows. First, the left and right vertical frames 21, the top plate 22, the upper frame 25 (lintel) and the lower frame 26 are assembled to form the frame body 2, thereby forming the storage section 20. The frame body 2 is attached to the framework of the building. On the other hand, the case side plates 47 are attached to the left and right ends of the case back plate 46 to form the shutter case 45, and the left and right ends of the shutter winding shaft 42 are connected to the bearing members 475 fixed to the case side plates 47 to make the shutter curtain 41 capable of being wound up and unwound. A communication unit 49 that receives remote operation signals is provided on the outer surface side of the side plate body 471 of the case side plate 47 shown on the right side in FIG. 2, and the communication unit 49 is connected to the shutter winding shaft 42 side by a wiring 6. Other wiring 6 that is connected to other devices etc. after the installation of the shutter 1 is arranged from the communication unit 49 through the wiring ports 471B, 461. In this manner, the shutter body 4 is formed. As the case side plates 47 described above, a plurality of types of case side plates 47 with different extension dimensions of the mounting pieces 472, 473 and the cap mounting pieces 474 are prepared to correspond to the slats 3 having different left and right dimensions depending on the type, such as steel or aluminum, and among the prepared plurality of types of case side plates 47, a case side plate 47 having mounting pieces 472, 473 and cap mounting pieces 474 with extension dimensions corresponding to the left and right dimensions of the slats 3 to be used is selected and used to configure the shutter case 45. For example, among the prepared case side plates 47, when the left and right dimensions of the slats 3 are large, a case side plate having mounting pieces 472, 473 and cap mounting pieces 474 with extension dimensions smaller by the large amount is selected, and, for example, among the prepared case side plates 47, when the left and right dimensions of the slats 3 are small, a case side plate having mounting pieces 472, 473 and cap mounting pieces 474 with extension dimensions larger by the small amount is selected. For this reason, when dealing with slats 3 having different left and right dimensions depending on the type, such as steel or aluminum, the visibility dimension of guide portion 478 can be made a common dimension, and there is no need to reconfigure guide portion 478 to have a new visibility dimension; it is sufficient to use case side panel 47 having mounting pieces 472, 473 and cap mounting piece 474 having an appropriate extension dimension for the slat 3 being used. Here, since the communication unit 49 is disposed on the outer surface side, not the inner surface side, of the case side plate 47, interference between the communication unit 49 and the slat 3 can be eliminated, and since it is unnecessary to provide the communication unit 49 with a guide function for guiding the slat, the configuration of the communication unit 49 can be simplified. Furthermore, since the wiring 6 from the communication unit 49 is also disposed along the outer surface of the side plate main body 471, it is possible to eliminate interference of the wiring 6 along the side plate main body 471 with the slat 3. For example, when the communication unit 49 and the wiring 6 are provided along the inner surface of the side plate main body 471, it is unnecessary to cover the wiring 6 with a slat guide (guide member) that suppresses interference between the wiring 6 and the slat 3, and it is possible to reduce the number of parts of the slat guide and simplify the configuration. Furthermore, since the communication unit 49 is surrounded by the case side plate 47, the vertical frame 21, the side cap 7, the top plate 22, and the inspection plate 23 after the shutter 1 is assembled, it is possible to improve waterproofing. Next, the shutter main body 4 is installed in the storage section 20 of the frame body 2. Specifically, the shutter main body 4 is inserted into the storage section 20 from the front, the shutter case 45 is arranged as shown in FIG. 6, the mounting piece 472 of the case side plate 47 is overlapped with the case mounting piece 52 of the back plate 5, and the mounting piece 472 is detachably screwed to the case mounting piece 52. In this state, the front part of the case side plate 47 is arranged to protrude forward from the vertical frame 21. With the shutter main body 4 attached to the frame body 2, a space is formed between the side plate main body 471 and the back plate 5, and the communication unit 49 and wiring 6 described above are arranged in this space. 7, the case side plate 47 has the mounting pieces 472 and the like extending outward in the Z-axis direction, so that the distance in the X-axis direction between the left and right side plate main bodies 471 can be shortened compared to the case side plate 60 having the mounting pieces 472 and the like extending inward in the Z-axis direction, and therefore the shutter winding shaft 42 can be shortened. Note that the top plate 22, the shutter winding shaft 42, and the slats 3 are not shown in FIG. Next, the side cap 7 is screwed to the cap attachment piece 474 of the case side plate 47. The screwed side cap 7 is disposed at a forward position relative to the vertical frame 21 in the Z-axis direction, and covers the outer surface side of the front part of the case side plate 47 at this position. There is a space in the X-axis direction between the case side plate 47 and the side cap 7 that is open at the front side as shown in FIG. 2, and the communication unit 49 described above is disposed between the side cap 7 and the case side plate 47. Therefore, even if the side cap 7 is attached, if the inspection plate 23 described later is removed, the maintenance button and the USB port provided on the communication unit 49 can be easily used. In addition, as shown in FIG. 6, when the side cap 7 is removed, the communication unit 49 disposed at the front part of the case side plate 47 is entirely exposed, so that the maintenance of the communication unit 49 can be easily performed by simply removing the side cap 7 without removing the shutter main body 4 from the frame body 2. Finally, while the inspection plate 23 shown in FIG. 1 is hung on the top plate 22, the left and right ends of the lower edge of the inspection plate 23 are removably screwed to the mounting pieces 473 of the case side plates 47 to assemble the shutter 1 shown in FIG.

[0017] [Variations] In the above embodiment, the shutter body 4 is electrically operated and the communication unit 49 and wiring 6 are arranged on the outer side of the case side panel 47 so as to be remotely operable, but the present invention is not limited to this and may be configured as a manual type in which the communication unit, wiring 6, etc. are not arranged on either the outer or inner side of the case side panel 47. In the above embodiment, the side caps 7 are configured to be attached to the case side plates 47. However, instead of this, the side caps may be configured to be attached to the vertical frames 21. In the embodiment, the wiring port 471B is formed in the case side plate 47, but in the case of a manual type configuration in which the wiring 6 is not passed through, the wiring port 471B may not be formed. Note that the wiring port 471B may be processed and formed when reassembling to an electric type. In the embodiment, the hole 471A formed in the side plate main body 471 is formed in a rectangular shape, but is not limited thereto, and may be formed in a half-moon shape, a semi-cylindrical shape, etc. In this case, the shape of the bearing member 475 may be changed from the above-mentioned shape in accordance with the shape of the hole 471A so that the bearing member 475 can be installed.

[0018] [Summary of the invention] (1) The shutter of the present invention comprises a frame body and a shutter body attached to the frame body so as to be able to wind and extend slats, the shutter body having a shutter winding shaft aligned in the left-right direction so as to be able to wind and extend the slats, and a shutter case supporting the shutter winding shaft, the shutter case having a case side plate which rotatably supports the shutter winding shaft and has a guide portion on its inner surface which guides the left-right edge of the slats, the case side plate having an attachment piece which extends towards the frame body in the left-right direction and is attached to the frame body side, the attachment piece having an extension dimension which corresponds to the left-right dimension of the slats. According to the shutter of the present invention, the mounting piece of the case side panel extends toward the frame body, so that, for example, when a remotely operable shutter body is used instead of a shutter body that does not have a remotely operable communication unit, equipment such as the communication unit of the shutter body can be placed in the space formed on the outer side of the case side panel, and since the mounting piece of the case side panel has an extension dimension corresponding to the left-right dimensions of the slats, the left-right positional relationship between the edge of the slat and the inner surface of the case side panel can be kept constant, eliminating the need to replace the guide part (slat guide part that suppresses lateral slippage of the slats) with one having a different left-right dimension. In addition, when the type of shutter body is changed, for example, when the shutter body with slats is changed from one made of steel to one made of aluminum, or when the shutter body with slats is changed from one made of aluminum to one made of steel, the left and right dimensions of the slats may also differ due to different design conditions, but in the present invention, a case side plate equipped with an attachment piece having an extension dimension corresponding to the left and right dimensions of the slats is selected. Therefore, even when the type of shutter body is different, the positional relationship in the left and right direction between the edge of the slat and the inner surface of the case side plate can be kept constant, eliminating the need to replace the guide part with one with a different left and right dimension. Therefore, when using various types of shutter bodies, there is no need to replace both the guide portion and the case side panel, and even when replacing with a case side panel having an attachment piece with a different extension dimension, a guide portion of common dimensions can be used, thereby improving compatibility of parts. Furthermore, for example, the left-right dimension between the case side plates can be made smaller than when using case side plates in which the mounting pieces are bent inward and extend inward, so costs can be reduced by shortening the shutter winding shaft. In addition, even when various types of shutter bodies are used, there is no need to change the left and right dimensions of the frame, so a common frame can be used, improving compatibility with existing shutters. (2) In the shutter of the present invention, the shutter body is installed so as to protrude forward from the frame body, a side cap covering the side of the shutter body is arranged at a forward position from the frame body, and the case side panel has the mounting piece and a cap mounting piece to which the side cap is attached, and both the mounting piece and the cap mounting piece may extend outward in the left-right direction. With this configuration, the cap mounting piece to which the side cap located at the forward position is attached extends outward in the left-right direction.Therefore, compared to, for example, the case where the cap mounting piece extends inward, the positional relationship between the entire inner surface of the case side panel and the edge of the slat can be kept constant.As a result, a guide portion of common dimensions can be used regardless of the size of the winding diameter of the slat relative to the shutter winding shaft of various shutter bodies. (3) In the shutter of the present invention, the shutter body may have a wiring port formed in the case side plate through which a wiring is passed. With this configuration, for example, when a shutter body having a communication unit is used instead of a shutter body not having a communication unit, and the communication unit is installed on the outer side of the case side panel, wiring from the communication unit can be passed through the above-mentioned wiring port without any additional processing of the case side panel, thereby improving workability. (4) The shutter assembly method of the present invention is a shutter assembly method for assembling the shutter of the present invention described above, characterized in that a plurality of case side panels having an extension dimension corresponding to the type of slat are prepared, and from the plurality of prepared case side panels, when the left-right dimension of the slat is large, a case side panel having an attachment piece with an extension dimension smaller by the larger amount is selected, and from the plurality of prepared case side panels, when the left-right dimension of the slat is small, a case side panel having an attachment piece with an extension dimension larger by the smaller amount is selected. With this configuration, the case side panels are selected as described above, so that the left-right positional relationship between the edges of the slats and the inner surface of the case side panel can be kept constant regardless of the type of shutter body, and therefore the guide portions attached to the inner surface of the case side panel can be standardized.
