Mode for Carrying Out the Invention

[0009] [Configuration of the Present Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In FIGS. 1 and 2, the electric shutter 1 according to the present embodiment is attached to the building structure and is arranged to be able to open and close the opening of the building. The electric shutter 1 includes a frame body 2 and a shutter main body (electric shutter device) attached to the frame body 2 so as to be able to wind up and pay out a shutter curtain 41 formed by connecting a plurality of slats 3. In the following description, the left - right direction of the electric shutter 1 is defined as the X - axis direction, the up - down direction of the electric shutter 1 is defined as the Y - axis direction, and the front - rear direction (indoors - outdoors direction, prospective direction) of the electric 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 includes 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 outdoor edge of the top plate 22, an upper frame (not shown in the figure) attached to the upper part of the left and right vertical frames 21 at a position below the top plate 22, and a lower frame 26 attached to the lower ends of the left and right vertical frames 21. On the left and right vertical frames 21, guide rails 211 for vertically guiding the left and right end portions of the slats 3 are mounted along the Y - axis direction. An engagement groove (not shown in the figure) is formed on the outdoor edge of the top plate 22 along the X - axis direction. The inspection plate 23 is attached such that its upper edge is hung in the engagement groove along the X - axis direction of the top plate 22, and the left and right end portions of its lower edge are screwed to attachment pieces 473 of a case side plate 47 described later. By removing the screws fixing the inspection plate 23 to the attachment pieces 473, it can be removed from the frame body 2.

[0011] This frame body 2 forms a housing portion 20 in which the shutter main body 4 is arranged by the upper parts of the left and right vertical frames 21, the top plate 22, and the upper frame. By attaching and detaching the inspection plate 23, the housing portion 20 can be opened and closed on the front side. Also, back plates are mounted on the upper parts of the left and right vertical frames 21 that partition the housing portion 20, and attachment pieces 472 of the case side plate 47 are detachably screwed to these back plates.

[0012] The shutter body 4 includes the shutter curtain 41 described above, a shutter winding shaft 42 pivotally supported by a shutter case 45 and capable of winding and unwinding the shutter curtain 41 along the X-axis direction by rotational drive, a tubular motor (not shown) as an electric motor connected to the shutter winding shaft 42 so as to be capable of rotationally driving the shutter winding shaft 42, a control unit (not shown) having an arithmetic unit, a storage device, etc. for controlling the rotation of the tubular motor, and a communication unit 49 connected to the control unit by a communication cable 492 (cable, see FIGS. 3 and 4) and receiving a signal from a remote controller such as a remote control and transmitting a command signal to the control unit. The communication unit 49 is disposed at a position in front of the vertical frame 21 and at the upper front position of a side plate body 471 described later whose side surface is covered by a side cap 7 described later. Its main body portion is housed in a housing 491. An operation unit such as a USB insertion port and a program button is disposed at the lower part of this housing 491. Also, a cable 61 connected to a power source and a cable 62 connected to other devices are provided for the electric shutter 1 from the indoor space through a rear wiring port 461. A part of the cables 61 and 62 is covered by a slat guide 51 described later, and the cable 61 is connected by a connector 63. The shutter curtain 41 is configured by rotatably connecting the plurality of slats 3 described above to each other. The uppermost slat 3 among the plurality of slats 3 is attached to the shutter winding shaft 42, and the lowermost slat 3 is attached to a seat plate that seats on the lower frame 26. For this reason, the shutter curtain 41 is configured to move 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 includes a case back plate 46 along the X-axis direction, and a pair of left and right case side plates 47 whose rear portions are attached to both left and right edges of the case back plate 46 and project forward. A resin side cap 7 that covers the side surface of the shutter body 4 is detachably attached to the case side plate 47 at a front position with respect to the upper part of the vertical frame 21 in the Z-axis direction. At both ends of the case back plate 46 in the X-axis direction, there are formed rear wiring ports 461 through which the above-described cables 61 and 62 are inserted. In the present embodiment, the communication cable 492, the cables 61 and 62, and the connector 63 are regarded as wirings 6.

[0013] As shown in FIGS. 2 to 4, the case side plate 47 includes 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 to the back plate from the front, a pair of mounting pieces 473 to which the left and right ends of the lower edge of the inspection plate 23 are detachably screwed, and a pair of cap mounting pieces 474 to which the side caps 7 are screwed. The cap mounting pieces 474 are arranged on the front side of the mounting pieces 472. The mounting pieces 472, 473, and the cap mounting pieces 474 extend inward in the X-axis direction toward the accommodation portion 20 side. The side plate main body 471 is in a flat plate shape, and the front portion thereof is arranged to protrude forward in the Z-axis direction from the vertical frame 21, and the side cap 7 is attached to the protruding portion (see FIGS. 1 and 2). At a substantially central position of the side plate main body 471, a bearing member 475 that rotatably supports the shutter winding shaft 42 is attached. The bearing member 475 has a shaft connection portion 476 to which the shutter winding shaft 42 is rotatably connected and a mounting portion 477 that is attached to the case side plate 47. The shaft connection portion 476 is formed in a substantially U shape and is arranged to protrude inward in the X-axis direction from the case side plate 47. The mounting portion 477 is bent in three directions outward (toward the outer peripheral side in the virtual plane orthogonal to the X-axis direction) from the shaft connection portion 476, is arranged along the inner surface of the side plate main body 471, and is fixed to the side plate main body 471 by riveting.

[0014] On the inner surface of the side plate body 471, in addition to the communication unit 49 described above, there are provided slat guides 51 and 52 for guiding the ends of the slats 3. Here, the housing 491 of the communication unit 49 also serves as an outer slat guide for guiding the ends of the slats 3. The slat guide 51 constitutes an inner slat guide fitted from the rear side into an upper opening formed in the housing 491 of the communication unit. The slat guide 52 is formed in a substantially rectangular shape and constitutes a lower slat guide detachably disposed so as to cover an operation portion formed at the lower part of the communication unit 49 from the lower side. The communication unit 49 and the slat guides 51 and 52 are arranged around the bearing member 475 (positions around the axis), and by guiding the slat 3, lateral displacement of the slat 3 is suppressed. As shown in FIGS. 3 to 5, the slat guide 51 has a plate-shaped guide main body portion 512 and a side plate portion 513 extending outward in the X-axis direction from the guide main body portion 512. The guide main body portion 512 and the side plate portion 513 form a substantially semi-circular arc-shaped storage space 514 between them and the inner surface of the side plate body 471, but there are no openings 515 and 516 through which the cables 61 and 62 are passed, and they are open. Further, the storage space 514 is open at the upper end portion and the lower end portion, and a fitting portion 517 is formed in the slat guide 51 at a portion forming a part of the opening at the upper end portion of the storage space 514, and this fitting portion 517 is fitted to the housing 491 of the communication unit 49. A part of the cables 61 and 62, which are wirings 6, and the connector 63 are stored in the slat guide 51.

[0015] As particularly shown in FIGS. 5(A) and 5(B), the above-described slat guide 51 is provided with a regulating portion 65 for regulating the position of the connector 63 in the storage space 514. The regulating portion 65 is disposed at a position near the opening at the upper end of the slat guide 51 in the storage space 514 and closer to the indoor side than the fitting portion 517. It has a vertical wall portion 66 as a first wall portion along the Y-axis direction, a lower horizontal wall portion 67 as a second wall portion extending in the Z-axis direction from the upper and lower ends of the vertical wall portion 66, and an upper horizontal wall portion 68 as a third wall portion, and is formed in a substantially U-shape. As described above, it is oriented to open on the side of the opening 515 (the indoor side with respect to the regulating portion 65) through which the cables 61 and 62 are passed. In the present embodiment, the vertical wall portion 66, the lower horizontal wall portion 67, and the upper horizontal wall portion 68 have the same X-axis dimension as the side plate portion 513 and are in contact with the case side plate 47 in the same manner as the side plate portion 513. However, for example, even if they have an X-axis dimension smaller than the side plate portion 513 and are not in contact with the case side plate 47, as long as it is possible to prevent a communication cable 492 or the like from entering between the connector 63 and the side plate main body 471 and causing the slat guide 51 to float inward in the X-axis direction from the case side plate 47. The vertical wall portion 66 is disposed between the communication unit 49 and the connector 63. The lower horizontal wall portion 67 is disposed between the mounting portion 477 (to be described later) of the bearing member 475 and the connector 63 at a position adjacent to the opening 516 in a direction orthogonal to the X-axis direction. The upper horizontal wall portion 68 extends from the opening 515 to the storage position P of the connector 63 and has the same Z-axis dimension as the lower horizontal wall portion 67. In addition, a recess 518 recessed inward in the X-axis direction is formed in the guide main body portion 512 at the storage position P, and by forming this recess 518, the connector 63 is configured to be easily disposed in the storage position P in a predetermined orientation. Also, in the present embodiment, there are three connectors 63 disposed at the storage position P. This regulating portion 65 partitions a space in which the connector 63 is stored by the vertical wall portion 66, the lower horizontal wall portion 67, and the upper horizontal wall portion 68.

[0016] In the above electric shutter 1, the cables 61 and 62 that enter the accommodation part 20 through the rear wiring opening 461 are connected to the respective connectors 63 and the communication unit 49 as shown by the dotted lines in FIG. 3. The slat guide 51 covers a part of the cables 61 and 62 and the respective connectors 63 from the inner side in the X-axis direction (the end side of the slat 3), and the fitting part 517 is fitted to the communication unit 49 and attached to the side plate main body 471. The cable 62 from the rear wiring opening 461 is arranged to be connected to the communication unit 49 through the opening 515. The cable 61 from the rear wiring opening 461 is arranged to be connected to the respective connectors 63 through the opening 515, and the cable 61 from the respective connectors 63 is connected to the shutter winding shaft 42 side through the opening 516. Here, the respective connectors 63 are arranged in the accommodation position P side by side in the Y-axis direction and are in a state of abutting against the substantially U-shaped restricting part 65. Also, a part of each connector 63 is arranged in the recess 518, suppressing the connector 63 from falling out toward the opening 515 side. Since the connectors 63 are arranged in this way, for example, it is possible to reduce the possibility that a communication cable 492 or the like enters between the connector 63 and the side plate main body 471, the connector 63 overlaps with the fitting part 517 in the X-axis direction, or the connector 63 enters the communication unit 49 side and the cable 61 is pulled, by the vertical wall part 66. Also, it is possible to reduce the possibility that the mounting part 477 of the bearing member 475 and the connector 63 overlap in the X-axis direction, by the lower horizontal wall part 67. Furthermore, since the upper horizontal wall part 68 regulates and guides the arrangement of the connectors 63, the respective connectors 63 can be easily arranged in the accommodation position P, and for example, it is possible to reduce the possibility that the connectors 63 overlap with each other in the X-axis direction.

[0017] [Modification Example] In the above-described embodiment, the restricting portion 65 has a vertical wall portion 66, a lower horizontal wall portion 67, and an upper horizontal wall portion 68, and is continuously formed in a substantially U-shape, but it is not limited thereto. The restricting portion 65 may have a shape capable of restricting the position of the connector 63. For example, it may be formed in an arc shape, or at least one of the vertical wall portion 66, the lower horizontal wall portion 67, and the upper horizontal wall portion 68 may be formed in a divided manner. Further, the restricting portion 65 may have only one of the wall portions of the vertical wall portion 66, the lower horizontal wall portion 67, and the upper horizontal wall portion 68. Even in this case, compared with the slat guide 51 in which the restricting portion 65 itself is not configured, the position of the connector 63 can be restricted, and the lifting of the slat guide 51 can be suppressed. In the above-described embodiment, the upper horizontal wall portion 68 extends from the opening 515 to the storage position P and is continuous with the upper end of the vertical wall portion 66, but it is not limited thereto. It may extend in the Z-axis direction within a range that does not reach the opening 515 from the storage position P. Even in this case, the connector 63 can be guided and restricted. Further, the upper horizontal wall portion 68 may have a Z-axis direction dimension equal to or less than that of the lower horizontal wall portion 67. In the above-described embodiment, the restricting portion 65 has a vertical wall portion 66, a lower horizontal wall portion 67, and an upper horizontal wall portion 68, but it is not limited thereto. The restricting portion 65 may be constituted by protrusions such as one or a plurality of shaft portions extending outward in the X-axis direction from the guide main body portion 512. In the above-described embodiment, the restricting portion 65 restricts the position of the connector 63 of the wirings 6, but it is not limited thereto. For example, when the connector 63 is not included in the wirings 6, the restricting portion 65 may be configured to restrict the position of a part of the cable 61. In the above-described embodiment, the positions of all of the plurality of connectors 63 are restricted by the restricting portion 65, but it is not limited thereto. When it does not cause the lifting of the slat guide 51, a part of the plurality of connectors 63 may be disposed outside the restricting portion 65 and may not be restricted by the restricting portion 65.

[0018] [Summary of the Invention] (1) The electric shutter of the present invention is an electric shutter device in which slats are attached to a frame so as to be wound up and paid out, and includes a shutter winding shaft that electrically winds up and pays out the slats, a shutter case having a case side plate that pivotally supports an end of the shutter winding shaft, a slat guide provided on an inner surface of the case side plate and guiding an end of the slat, and wirings housed in the slat guide between the case side plate and the slat guide. The slat guide is provided with a regulating portion that abuts against the wirings and regulates the positions of the wirings. According to the electric shutter of the present invention, since the regulating portion that abuts against the wirings and regulates their positions is provided on the slat guide, it is possible to prevent foreign matter from entering the wirings side, prevent the wirings themselves from being arranged at positions deviated from a predetermined storage position, prevent interference with other components, and prevent the wirings from overlapping each other. Therefore, it is possible to suppress the lifting of the slat guide from the case side plate due to these factors. (2) In the electric shutter of the present invention, the wirings may have connectors, and the regulating portion may abut against the connectors and regulate the positions of the connectors. According to such a configuration, since the positions of the connectors having a predetermined shape are regulated, the positions of cables or the like connected to the connectors are also stably arranged. Therefore, the occurrence of the factors causing the above-described lifting of the slat guide can be more preferably reduced. (3) In the electric shutter of the present invention, a communication unit that fits into the slat guide may be provided on the inner surface of the case side plate, and the regulating portion may have a first wall portion disposed between the communication unit and the connector. According to such a configuration, since the first wall portion described above is provided, the communication cable or the connector itself of the communication unit can be restricted from moving between the communication unit side and the slat guide side by the first wall portion. Therefore, for example, the communication cable of the communication unit may enter between the connector and the case side plate, or the connector may enter between the fitting portion of the slat guide that fits with the communication unit and the case side plate. Also, the cable may be pulled while the connector is inserted into the communication unit side, and the risk of the slat guide lifting off from the case side plate due to these factors can be reduced. (4) In the electric shutter of the present invention, a bearing member for pivotally supporting an end portion of the shutter winding shaft is attached to the case side plate. The bearing member has a mounting portion attached to the inner surface of the case side plate. The slat guide is disposed at a position around the axis with respect to the bearing member, and the restricting portion may have a second wall portion disposed between the mounting portion and the connector. According to such a configuration, the second wall portion described above can suppress the connector from riding up on the mounting portion of the bearing member. Therefore, the lifting of the slat guide from the case side plate due to this factor can be reduced. (5) In the electric shutter of the present invention, the slat guide may have an opening through which the wirings are passed, and the slat guide may have a third wall portion extending from the opening to the storage position of the connector. According to such a configuration, the wirings passed through the opening of the slat guide can be regulated and guided by the third wall portion, and the connector can be easily stored in a predetermined storage position. The risk of the slat guide lifting off from the case side plate due to the connectors overlapping each other can be reduced. (6) In the electric shutter of the present invention, the restricting portion may have a first wall portion along the vertical direction, and second and third wall portions extending from the upper and lower end portions of the first wall portion in the indoor-outdoor direction. The space in which the connector is stored may be partitioned by the first wall portion, the second wall portion, and the third wall portion. According to such a configuration, when arranging the connector in the storage space, the connector can be easily placed at the storage position in the storage space by making the connector abut against the first wall portion while guiding the connector by the second wall portion and the third wall portion, and the lifting of the slat guide as described above can be suppressed.
