[0003] [Patent Document 1] Japanese Patent Application Publication No. 9-88453 [Patent Document 2] JP 2006-283328 A [Patent Document 3] JP 2010-101089 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the shutter storage unit is usually attached to the exterior wall of a building first, the shutter storage unit is hooked onto the mounting bracket and temporarily fixed, and then permanently fixed with screws, etc., but since the shutter storage unit needs to be raised and lowered when hooked onto the mounting bracket, space is required above the shutter storage unit to allow for lifting and lowering, which creates additional fitting constraints. Because the shutter storage unit is attached to the exterior wall of a building, if there are eaves or overhangs close to the upper part of the installation position, there is no space to lift it up, which causes problems such as making installation impossible.

[0005] The present invention has been made in consideration of the above-mentioned situation, and its purpose is to provide a mounting structure for a shutter storage unit that eliminates the need for space in the shutter storage unit for raising and lowering it, making it easier to install the shutter storage unit on an exterior wall. [Means for solving the problem]

[0006] Next, means for solving the above problems will be described with reference to the drawings corresponding to the embodiments. The mounting structure for a shutter storage unit according to claim 1 of the present invention is a mounting structure for a shutter storage unit that fixes a shutter storage unit 15 that stores a shutter curtain 13 in a rollable manner to an exterior wall 17 of a building, At least one pair of locking claws 55 are fixed to the surface of the outer wall 17, each having a bent portion 56; At least a pair of insertion holes 57 formed in a back plate portion 47 facing the outer wall 17 of the shutter storage portion 15 and into which the locking claws 55 are inserted; Equipped with The locking claw 55 is inserted into the entry hole 57 and the shutter storage section 15 is slid horizontally along the outer wall 17, so that the bent portion 56 is positioned at a locking portion 65 formed in a part of the entry hole 57, and the bent portion 56 supports the locking portion 65.

[0007] In this mounting structure for the shutter storage section, a pair of left and right base plates 45 are fixed to the exterior wall 17 of the building, and each base plate 45 is provided with a locking claw 55 having a bent portion 56 on its surface. In the shutter storage section 15, at least a pair of entry holes 57 into which the locking claws 55 are inserted are formed in the back panel portion 47. The entrance hole 57 has a locking portion 65 formed in a part thereof. When attaching the shutter storage section 15 to the exterior wall 17, first, the pair of entry holes 57 of the back plate section 47 are inserted into the locking claws 55 provided on the pair of left and right base plates 45 fixed to the exterior wall 17. By inserting the locking claws 55 into the entry holes 57 of the back plate section 47, the locking claws 55 protruding through the bent portions 56 of the shutter storage section 15 are positioned more inward of the back plate section 47 than the shutter storage section 15. When the shutter storage section 15 is slid horizontally along the outer wall 17 with the locking claw 55 inserted into the entrance hole 57, the bent portion 56, which is the base end of the locking claw 55, is positioned in the locking portion 65. In other words, the locking claw 55 locks onto the back side of the locking portion 65, restricting the movement of the back plate portion 47 in the direction away from the outer wall 17. As a result, the locking portion 65 of the shutter storage section 15 locks onto the locking claw 55, completing the temporary fixation to the outer wall 17. In this mounting structure for the shutter housing section, the entrance hole 57 of the shutter housing section 15 is inserted into the locking claw 55 protruding from the base plate 45 fixed to the exterior wall 17 in a direction perpendicular to the exterior wall 17, that is, from the front of the exterior wall 17. Then, with the locking claw 55 inserted into the entrance hole 57, the shutter housing section 15 can move horizontally as it is, and the locking claw 55 can be locked with the locking section 65. In other words, in the mounting structure for the shutter housing section, it is not necessary to raise and lower the shutter housing section 15 in order to lock the shutter housing section 15 with the locking claw 55. Since there is no need to lift it upward, the shutter housing section 15 can be mounted even in places where the eaves, eaves ceiling, or overhang are close by.

[0008] The mounting structure for a shutter housing part according to claim 2 of the present invention is the mounting structure for a shutter housing part according to claim 1, The locking claw 55 is formed to protrude upward, The entry hole 57 is provided with a claw receiving groove 61 formed in the back plate portion 47, the claw receiving groove 61 being connected to the lower end of one side portion 63 in a horizontal direction away from the entry hole 57, The locking claw 55 is inserted into the entry hole 57 and the shutter storage section 15 is slid horizontally along the outer wall 17, so that the bent portion 56 is positioned in the claw receiving groove 61 and supports the locking portion 65 connected to the edge portion 63 and formed on the upper edge of the claw receiving groove 61.

[0009] In this mounting structure for the shutter storage section, a claw receiving groove 61 is formed in the entrance hole 57. The claw receiving groove 61 is formed by cutting into the back plate 47 from the lower end of one side 63 of the entrance hole 57 in the horizontal direction away from the entrance hole 57. The portion connected to one side 63 of the entrance hole 57 and formed on the upper edge of the claw receiving groove 61 serves as an engagement portion 65. When attaching the shutter storage section 15 to the outer wall 17, first, the pair of entrance holes 57 of the back plate section 47 are inserted into the locking claws 55 provided on the pair of left and right base plates 45 fixed to the outer wall 17. By inserting the locking claws 55 into the entrance holes 57 of the back plate section 47, the locking claws 55 protruding upward are positioned inside the shutter storage section 15 relative to the back plate section 47. When the shutter storage section 15 is slid horizontally along the outer wall 17 with the locking claw 55 inserted into the entrance hole 57, the bent portion 56, which is the base end of the locking claw 55, enters the claw receiving groove 61. In other words, the locking claw 55 is locked to the back side of the locking portion 65 by being disposed in the claw receiving groove 61, and the movement of the back plate portion 47 in the direction away from the outer wall 17 is restricted. As a result, the locking portion 65 of the shutter storage section 15 is locked to the locking claw 55, and temporary fixation to the outer wall 17 is completed. In this mounting structure for the shutter housing section, the entrance hole 57 of the shutter housing section 15 is inserted into the locking claw 55 protruding from the base plate 45 fixed to the exterior wall 17 in a direction perpendicular to the exterior wall 17, that is, from the front of the exterior wall 17. Then, with the locking claw 55 inserted into the entrance hole 57, the shutter housing section 15 can move horizontally as it is, and the locking claw 55 can be locked with the locking section 65. In other words, in the mounting structure for the shutter housing section, it is not necessary to raise and lower the shutter housing section 15 in order to lock the shutter housing section 15 with the locking claw 55. Since there is no need to lift it upward, the shutter housing section 15 can be mounted even in places where the eaves, eaves ceiling, or overhang are close by.

[0010] The mounting structure for a shutter housing part according to claim 3 of the present invention is the mounting structure for a shutter housing part according to claim 2, The back plate portion 47 has the entry hole portions 57 formed on both the left and right sides of the locking portion 65, and the entry hole portions 57 on both the left and right sides are connected by the claw receiving groove 61.

[0011] In this mounting structure for the shutter housing section, the entrance hole portions 57 are provided on both the left and right sides of the locking portion 65. The entrance hole portions 57 on both the left and right sides are connected by a claw receiving groove 61. In this shutter housing section 15, when the locking claw 55 is inserted into the entrance hole 57 on the left side when viewed from the front, the shutter housing section 15 slides to the left and the locking portion 65 locks into the locking claw 55, temporarily fixing it. Conversely, when the locking claw 55 is inserted into the entrance hole 57 on the right side when viewed from the front, the shutter housing section 15 slides to the right and the locking portion 65 locks into the locking claw 55, temporarily fixing it. This allows the mounting structure for the shutter housing section 15 to be mounted regardless of whether the shutter housing section 15 is slid to the left or right.

[0012] The mounting structure for a shutter housing part according to claim 4 of the present invention is the mounting structure for a shutter housing part according to any one of claims 1 to 3, The shutter storage section 15 is provided with a side plate section 33 perpendicular to the back plate section 47, The side plate portion 33 is characterized by having an observation hole 67 through which the locking claw 55 can be seen from the outside.

[0013] In this mounting structure of the shutter storage section, the entry hole 57 is inserted into the locking claw 55, the shutter storage section 15 is slid, and the temporary fixed state in which the locking claw 55 is engaged with the locking section 65 can be visually confirmed from the outside of the side plate section 33 through an inspection hole 67 drilled in the side plate section 33. This allows the worker to visually check whether or not the locking portion 65 is locked with the locking claw 55. This makes it possible to prevent the worker from moving on to the main fixing work in an incomplete provisionally locked state.

[0014] The mounting structure for a shutter housing part according to claim 5 of the present invention is the mounting structure for a shutter housing part according to claim 4, The shutter housing portion 15 is characterized in that a decorative cover 35 is attached to cover the side plate portion 33 as well as the confirmation hole 67.

[0015] In this mounting structure for the shutter housing section, a decorative cover 35 is attached to the side plate sections 33 provided on both sides of the shutter housing section 15. The decorative cover 35 covers the side plate sections 33 from above, the front, below, and the sides, and can also cover and conceal the confirmation hole 67 drilled in the side plate sections 33 at the same time. As a result, the mounting structure for the shutter housing section can improve the appearance of the shutter housing section 15. In addition, since the confirmation hole 67 leading from the outside to the inside of the shutter housing section 15 can be covered, the infiltration of rainwater, etc. through the confirmation hole 67 can also be prevented.

[0016] The mounting structure for a shutter housing part according to claim 6 of the present invention is the mounting structure for a shutter housing part according to any one of claims 1 to 5, The locking claw 55 is provided on a base plate 45 fixed to the outer wall 17. A cable 85 that is electrically connected to the electrical components housed in the shutter housing portion 15 is led out from the shutter housing portion 15, A through hole is drilled in the base plate 45, which communicates with an introduction hole drilled in the outer wall 17 and through which the cable 85 is inserted. The through hole is characterized by having a gasket 77 that is positioned between the inserted cable 85 and the inner periphery of the through hole to support the cable 85 in the center of the through hole and narrow the gap between the inner periphery of the through hole and the cable 85.

[0017] In this mounting structure for a shutter housing section, a cable 85 is led out from the shutter housing section 15. The cable 85 is conductively connected to electrical components housed in the shutter housing section 15. The board 45, which is provided with a locking claw 55 for temporarily fixing the shutter housing section 15 to the outer wall 17, has a through hole for inserting the cable 85 therethrough. The substrate 45 is fixed to the outer wall 17 so that the through hole is in communication with an introduction hole for a cable 85 drilled in the outer wall 17. The through hole is provided with a packing 77 that supports the cable 85 in the center of the through hole. The packing 77 has a plurality of flexible pieces 81 that narrow the gap between the inner circumference of the through hole and the cable 85. The packing 77 has an inner hole of an annular packing main body 79 that is almost completely blocked by a plurality of fan-shaped flexible pieces 81 that are close to each other in the circumferential direction. Each flexible piece 81 is capable of elastic deformation independently due to radial slits 83. Cable 85 that has passed through packing 77 is held in a state of being sandwiched in slit 83 by elastically deforming flexible piece 81. As a result, cable 85 passed through the through hole is supported in the center of the through hole by packing 77, and the gap between the cable 85 and the inner periphery of the through hole is narrowed by flexible piece 81. Effect of the Invention

[0018] According to the mounting structure for the shutter storage unit described in claim 1 of the present invention, the shutter storage unit does not require space for raising and lowering, i.e., there is no need to lift it upwards, so the shutter storage unit can be mounted even in places where the eaves, eaves ceiling, or overhang are close by, making it easier to install the shutter storage unit on the exterior wall.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the appearance of a window shutter device 11 equipped with a mounting structure for a shutter storage section. The mounting structure for the shutter storage unit according to this embodiment is a mounting structure for fixing the shutter storage unit 15, which stores the shutter curtain 13 in a freely rollable manner, to the exterior wall 17 of a building. The mounting structure for the shutter storage unit can be suitably used for, for example, a window shutter device 11 for a building.

[0026] The window shutter device 11 is attached to the outside of a sash window 19 that constitutes a window portion of a house. An opening 21 is provided in an exterior wall 17 of the house. A sash window 19 is attached to this opening 21. The window shutter device 11 has a shutter curtain 13. The shutter curtain 13 rises and falls on the outside of the exterior wall 17 to cover the sash window 19. The shutter curtain 13 is composed of a plurality of connected slats 23 made of aluminum or steel.

[0027] The shutter curtain 13 is configured such that multiple slats 23 are connected in a rollable planar shape by engaging both ends of adjacent slats 23 along the longitudinal direction. A seat plate 25 is attached to the leading end of the shutter curtain 13 in the unwinding direction. The seat plate 25 sits on a lower frame 27 when the shutter curtain 13 is lowered. The shutter curtain 13 is guided in its rising and lowering by a pair of guide rails 29 provided on the left and right sides of the sash window 19. The guide rails 29 extend in the rising and lowering direction of the shutter curtain 13, and guide each side of the shutter curtain 13 by sandwiching it from the front and back. Each of the pair of guide rails 29 is fixed to the inside of a pair of outer frames 31 attached to the outer wall 17 on the left and right sides of the sash window 19.

[0028] The pair of outer frames 31 extend in the ascending and descending direction of the shutter curtain 13, and their lower ends are connected by the lower frame 27. The upper end sides of the pair of outer frames 31 support the load of the shutter storage section 15. The shutter storage section 15 is formed in a substantially rectangular parallelepiped shape extending in the frontage direction of the sash window 19. Decorative covers 35 are attached to the side plate sections 33 at both ends of the longitudinal direction of the shutter storage section 15, positioned so as to protrude slightly outward from the outer frames 31.

[0029] FIG. 2 is an exploded perspective view of the mounting structure of the shutter housing portion. The upper end of the pair of outer frames 31 opens an intake port for the shutter curtain 13 in the guide rail 29. When the shutter storage section 15 is placed on the upper end of the outer frame 31, this intake port engages with a guide rail connection section 37 formed on the side plate section 33 of the shutter storage section 15. The upper ends of the pair of outer frames 31 are connected and fixed by an upper frame 39 arranged between the guide rail 29 and the outer wall 17. The upper frame 39 is a so-called lintel. The upper frame 39 extends parallel to the lower frame 27, and a cross section perpendicular to the extension direction is approximately L-shaped by a horizontal plate 41 and a vertical plate 43. The left and right ends of the horizontal plate 41 of the upper frame 39 are fixed to the upper end of the outer frame 31, and the vertical plate 43 is fixed to the outer wall 17.

[0030] A substrate 45 is fixed to the outer wall 17 above the pair of outer frames 31. In this embodiment, the substrate 45 is formed in a vertically long rectangular shape. The substrate 45 has a vertical length that is approximately equal to the vertical height of the shutter housing section 15. Meanwhile, the shutter housing section 15 is provided with a back plate portion 47 on a surface facing the outer wall 17. The back plate portions 47 are provided on both sides of the longitudinal direction of the shutter housing section 15 at a distance so as to correspond to the respective substrates 45. In other words, the shutter housing section 15 is open between the back plate portions 47 on both the left and right sides. This open portion is blocked by the outer wall surface when the shutter housing section 15 is attached to the outer wall 17.

[0031] The substrate 45 has, for example, four substrate fixing holes 49 arranged spaced apart in the vertical direction. Fixing members 51 such as screws are inserted into these substrate fixing holes 49, and the substrate 45 is fixed to the exterior wall 17, preferably to a structural body 59 such as a pillar. In this embodiment, the uppermost one of the four substrate fixing holes 49 is used for fixing the decorative cover described above.

[0032] An upper edge fixing portion 53 that stands vertically upward along the outer wall 17 is formed at the rear end of the upper surface of the shutter housing portion 15 across the longitudinal direction of the shutter housing portion 15. This upper edge fixing portion 53 is used when the shutter housing portion 15 is finally fixed to the outer wall 17.

[0033] On the surface of each of the left and right base plates 45, a locking claw 55 is formed that protrudes upward via a bent portion 56. The locking claw 55 is used when temporarily fixing the shutter storage section 15 to the outer wall surface. In addition, at least a pair of entrance holes 57 are formed in the back plate portion 47 facing the base plate 45, into which the locking claws 55 are inserted from a direction perpendicular to the outer wall 17, i.e., into which the locking claws 55 can be inserted from the front of the outer wall 17. In other words, the entrance holes 57 are formed to a size that allows the locking claws 55 to be inserted while ensuring sufficient space above, below, left and right.

[0034] FIG. 3 is an exploded perspective view of the main parts of the base plate 45 and the back plate portion 47. As shown in FIG. The substrate 45 is fixed to a frame 59 such as a pillar that supports an exterior wall material. The substrate 45 may abut against the upper end of the outer frame 31, thereby supporting the load received by the substrate 45 on the outer frame 31. In this embodiment, two locking claws 55 are formed on the surface of the outer frame 31, one above the other. Thus, a pair of left and right locking claws 55 are provided on each of the pair of left and right substrates 45, totaling four locking claws in two rows, one above the other. The number of locking claws 55 is not limited to this.

[0035] Meanwhile, the back plate portion 47 in which the entrance hole portion 57 is formed has a claw receiving groove 61. In this embodiment, the entrance hole portion 57 is formed in a rectangular shape having a size that allows the locking claw 55 to be inserted as described above, and the claw receiving groove 61 is formed in a slit shape by cutting the back plate portion 47 in a horizontal direction away from the entrance hole portion 57 from the lower end of one vertical side portion 63 of the entrance hole portion 57. In this embodiment, the side portion 63 of the entrance hole portion 57 and the upper edge of the claw receiving groove 61 are connected so as to be perpendicular to each other, and the upper edge portion of the claw receiving groove 61 becomes the locking portion 65 that locks the locking claw 55. That is, after the locking claw 55 is inserted into the entrance hole portion 57, the shutter storage portion 15 is slid in the horizontal direction (left and right direction) along the outer wall 17, so that the locking claw 55 is placed in the claw receiving groove 61 and supports the locking portion 65.

[0036] Note that the claw receiving groove 61 may be formed so that its width in the height direction from the bottom side of the entrance hole 57 (slit interval width) is equal to or greater than the standing height of the locking claw 55, that is, a height that allows the locking claw 55 to be inserted from the front. With the claw receiving groove 61 according to such a modification, it is possible to hook the locking portion 65 onto the locking claw 55 by raising and lowering it, as in the conventional case.

[0037] In this embodiment, two entrance holes 57 are formed in the back plate portion 47 on the left and right sides sandwiching the locking portion 65. The entrance holes 57 on the left and right sides are connected by a claw receiving groove 61. That is, in this embodiment, the pair of entrance holes 57 and the locking portion 65 provided between the pair of entrance holes 57 have a concave shape in front view with the locking portion 65 hanging down at the center. A total of four such concave shapes are formed corresponding to the respective locking claws 55.

[0038] FIG. 4 is an explanatory diagram showing the process of locking between the entrance hole 57 and the locking claw 55 in (a) to (c). In the mounting structure of the shutter storage section, for example, when the locking claw 55 is inserted into the right-side entrance hole 57 when viewed from the front (see FIG. 4(a)), the shutter storage section 15 slides to the right (arrow in FIG. 4(b)). When the shutter storage section 15 is slid to the right, the locking portion 65 enters behind the locking claw 55, that is, between the surface of the substrate 45 and the locking claw 55. As a result, the locking portion 65 of the shutter storage section 15 locks with the locking claw 55 (see FIG. 4(c)), and the shutter storage section 15 is temporarily fixed, that is, a part of the load is supported. In this embodiment, the sliding movement of the shutter storage section 15 causes the four locking portions 65 to simultaneously lock with the four locking claws 55, and the shutter storage section 15 is supported by these four locking claws 55.

[0039] FIG. 5 is an enlarged perspective view of a main portion showing an observation hole 67 provided in the side plate portion 33. As shown in FIG. The shutter storage section 15 is provided with a side plate section 33 that is perpendicular to the back plate section 47. The side plate section 33 is provided with a confirmation hole 67 that allows the locking claws 55 to be visually confirmed from the outside. Therefore, the side plate section 33 is provided with a pair of upper and lower confirmation holes 67 corresponding to each of the pair of upper and lower locking claws 55 provided on the base plate 45. The confirmation hole 67 can be formed, for example, in a rectangular shape. The shape of the confirmation hole 67 is not limited thereto. For example, the confirmation hole 67 may be a circle, an oval, an ellipse, or a polygon other than a rectangle.

[0040] FIG. 6 is an exploded perspective view of the shutter housing section before the decorative cover 35 is attached to the side plate portion 33. FIG. A decorative cover 35 that covers the side plate portion 33 as well as the confirmation hole 67 is attached to the shutter storage portion 15. The decorative cover 35 is made of, for example, a flexible resin material, and covers the side plate portion 33 from above, the front, below, and the sides, thereby simultaneously covering and concealing the confirmation hole 67 drilled in the side plate portion 33. The decorative cover 35 has a flange portion 69 parallel to the outer wall 17 at an edge portion facing the outer wall 17. The decorative cover 35 covers the side plate portion 33 by fixing the screws 51 inserted through two upper and lower cover fixing holes 71 drilled in the flange portion 69 to the board fixing hole 49 and the outer frame fixing hole 75 provided in the bent portion 73 of the outer frame 31.

[0041] When the decorative cover 35 is attached to the side plate portion 33 of the shutter storage portion 15, the upper edge fixing portion 53 is also fixed to the outer wall 17 by the screw 51.

[0042] FIG. 7 is an enlarged perspective view of a main portion of substrate 45 having a through hole (not shown) with packing 77 provided therein. The mounting structure of the shutter housing may be such that a through hole with a packing 77 is provided in the base plate 45. The packing 77 is arranged, for example, inside the lower locking claw 55, at a position that communicates with an introduction hole drilled in the outer wall 17. The packing 77 is integrally molded from an elastic material such as rubber. The packing 77 has an annular packing main body 79 whose inner hole is almost completely blocked by a plurality of fan-shaped flexible pieces 81 that are adjacent to each other in the circumferential direction. Each flexible piece 81 is capable of elastic deformation independently due to radial slits 83.

[0043] FIG. 8 is an exploded perspective view of the essential parts in which a cable 85 connected to the shutter storage portion 15 is passed through a packing 77. As shown in FIG. The shutter storage section 15 contains electrical components such as an opening / closing device equipped with a motor for opening and closing the shutter curtain 13, various sensors, and a control device that receives signals from the sensors and controller to drive and control the opening / closing device. Signal lines and power lines connected to these electrical components are led out of the shutter storage section 15 as cables 85.

[0044] The cable 85 led out from the shutter storage section 15 is passed through the through hole of the base plate 45 and pulled into the building. At this time, the cable 85 passes through the packing 77 attached to the through hole, and is supported in the center of the through hole by the elastic deformation of each flexible piece 81. The packing 77 also narrows the gap between the inner circumference of the through hole and the cable 85.

[0045] The cables 85 inserted through the through holes are mainly one each of a 100V power line (with an oval cross section, approximately 13 mm wide x approximately 6.5 mm thick) and a signal line (with a cross section of approximately φ6.5 mm). The diameter of the introduction hole drilled in the exterior wall 17 is often approximately φ30 mm, taking into consideration the ease of work when passing the cables 85 through. For this reason, if the packing 77 is not provided, insects and small animals can enter. By providing the packing 77 to the through hole of the board 45, the introduction hole diameter can be narrowed and the gap can be narrowed, preventing the entry of small animals such as insects and birds and reducing wind blowing into the wall. In addition, when the edge of the introduction hole drilled in the exterior wall 17 is rough, for example, when there is a burr, the presence of the packing 77 prevents the burr from coming into contact with the cable 85, making it easier to pull the cable 85 into the building and also making it possible to suppress damage to the cable 85.

[0046] Next, the operation of the above-mentioned configuration will be described.

[0047] In the mounting structure for the shutter storage unit according to this embodiment, a pair of left and right boards 45 are fixed to the exterior wall 17 of a building. Each board 45 has a total of four locking claws 55, one pair at the top and one pair at the bottom, that protrude upward on the surface.

[0048] Meanwhile, in the shutter storage section 15, four entry holes 57 (left and right and top and bottom pairs) are formed in the back plate section 47 into which the locking claws 55 are inserted from a direction perpendicular to the outer wall 17. In actual installation, each entry hole 57 is brought close to each locking claw 55 in a direction perpendicular to the outer wall 17, that is, from the front of the outer wall 17, and the locking claws 55 are inserted inside the entry hole 57.

[0049] A claw receiving groove 61 is formed in communication with the entrance hole 57. The claw receiving groove 61 is formed by cutting the back plate 47 from the lower end of one side 63 of the entrance hole 57 in a horizontal direction away from the entrance hole 57. In other words, the entrance hole 57 and the claw receiving groove 61 are substantially L-shaped in a front view. Since the entrance hole 57 and the claw receiving groove 61 are substantially L-shaped, the back plate 47 has an engagement portion 65 extending from a portion sandwiched between the two perpendicular sides of the one side 63 of the entrance hole 57 and the claw receiving groove 61 to the upper edge of the claw receiving groove 61.

[0050] When attaching the shutter storage section 15 to the outer wall 17, first, the pair of entrance holes 57 of the back plate section 47 are inserted into the locking claws 55 provided on the pair of left and right base plates 45 fixed to the outer wall 17. By inserting the locking claws 55 into the entrance holes 57 of the back plate section 47, the locking claws 55 protruding upward are positioned inside the shutter storage section 15 relative to the back plate section 47.

[0051] When the shutter storage section 15 is slid horizontally along the outer wall 17 with the locking claw 55 inserted into the entrance hole 57, the bent portion 56, which is the base end of the locking claw 55, enters the claw receiving groove 61. In other words, the locking claw 55 is locked to the back side of the locking portion 65 by being disposed in the claw receiving groove 61, and the movement of the back plate portion 47 in the direction away from the outer wall 17 is restricted. As a result, the locking portion 65 of the shutter storage section 15 is locked to the locking claw 55, and temporary fixation to the outer wall 17 is completed.

[0052] In this mounting structure for the shutter housing section, the entrance hole 57 of the shutter housing section 15 is inserted into the locking claw 55 protruding from the base plate 45 fixed to the exterior wall 17 in a direction perpendicular to the exterior wall 17, that is, from the front of the exterior wall 17. Then, with the locking claw 55 inserted into the entrance hole 57, the shutter housing section 15 can move horizontally as it is, and the locking claw 55 can be locked with the locking section 65. In other words, in the mounting structure for the shutter housing section, it is not necessary to raise and lower the shutter housing section 15 in order to lock the shutter housing section 15 with the locking claw 55. Since there is no need to lift it upward, the shutter housing section 15 can be mounted even in places where the eaves, eaves ceiling, or overhang are close by.

[0053] The state in which the locking portion 65 of the shutter housing section 15 is locked to the locking claw 55 is a state in which the shutter housing section 15 is temporarily fixed to the locking claw 55. In this temporarily fixed state, the load of the shutter housing section 15 is supported mainly by the upper ends of the pair of outer frames 31 fixed to both sides of the opening 21. Therefore, only a portion of the load of the shutter housing section 15 is applied to the locking claw 55. With the shutter housing section 15 temporarily fixed, the worker can use both hands to permanently fix the shutter housing section 15 to the outer wall 17 with fixing members 51 such as screws, without supporting the shutter housing section 15.

[0054] In addition, in the mounting structure of this shutter storage section, entrance holes 57 are provided on both the left and right sides of the locking portion 65. In other words, the back plate portion 47 is structured so that the locking portion 65 is provided between the entrance holes 57 on both the left and right sides. The entrance holes 57 on both the left and right sides are connected by a claw receiving groove 61. The entrance holes 57 on both the left and right sides and the single claw receiving groove 61 are concave-shaped, with the locking portion 65 hanging down from the center.

[0055] In this shutter housing section 15, when the locking claw 55 is inserted into the left-side entrance hole 57 in a front view, the shutter housing section 15 is slid to the left, and the locking portion 65 is locked to the locking claw 55, thereby temporarily fixing the shutter housing section 15. Conversely, when the locking claw 55 is inserted into the right-side entrance hole 57 in a front view, the shutter housing section 15 is slid to the right, and the locking portion 65 is locked to the locking claw 55, thereby temporarily fixing the shutter housing section 15. This allows the shutter housing section 15 to be attached by sliding it to either the left or right. As a result, even if another member such as a wall is close to one of the side plate portions 33 of the shutter housing section 15 and the shutter housing section 15 cannot slide, the shutter housing section 15 can be slid to the other side and temporarily fixed.

[0056] Furthermore, in this mounting structure of the shutter storage section, the locking claw 55 is inserted into the entry hole 57, the shutter storage section 15 is slid, and the provisionally fixed state in which the locking claw 55 is engaged with the locking section 65 can be visually confirmed from the outside of the side plate section 33 through an inspection hole 67 drilled in the side plate section 33. From the confirmation hole 67, it can be visually confirmed that the locking claw 55 is positioned on the inside of the shutter storage section 15 of the locking section 65, which is opposite the outer wall 17, across the locking section 65, and that the locking state is being confirmed.

[0057] This allows the worker to check whether the locking portion 65 is locked to the locking claw 55 without any bias in the sliding direction. Therefore, it is possible to prevent the worker from moving to the main fixing work in an incomplete temporary locking state. As a result, the locking state between the locking claw 55 and the locking portion 65 can be visually confirmed from the outside through the confirmation hole 67, which prevents temporary fixing failure and improves the safety of the construction by checking the installation position of the shutter storage portion 15 relative to the exterior wall 17 and the already installed outer frame 31.

[0058] In addition, in this mounting structure for the shutter housing section, a decorative cover 35 is attached to the side plate sections 33 provided on both sides of the shutter housing section 15. The decorative cover 35 covers the side plate sections 33 from above, the front, below, and the sides, and can also cover and hide the confirmation hole 67 drilled in the side plate sections 33 at the same time.

[0059] This allows the mounting structure of the shutter housing section to improve the appearance of the shutter housing section 15. In addition, since the confirmation hole 67 that leads from the outside to the inside of the shutter housing section 15 can be covered, it is possible to prevent the intrusion of rainwater, dust, insects, etc. through the confirmation hole 67. As a result, by covering the confirmation hole 67, it is possible to improve the appearance of the shutter housing section 15 and also improve waterproofing and prevention of intrusion of foreign objects.

[0060] Furthermore, in this shutter storage section mounting structure, a cable 85 is led out from the shutter storage section 15. The cable 85 is conductively connected to the electrical components housed in the shutter storage section 15. The board 45, which is equipped with a locking claw 55 for temporarily fixing the shutter storage section 15 to the exterior wall 17, has a through hole for inserting the cable 85. Before the board 45 is mounted on the exterior wall 17, a cable lead-in hole for leading the cable 85 into the building is drilled and constructed. The board 45 is mounted on the exterior wall 17 with its through hole aligned with the lead-in hole.

[0061] This through hole is provided with packing 77 that supports cable 85 in the center of the through hole. Packing 77 has multiple flexible pieces 81 that narrow the gap between the inner periphery of the through hole and cable 85. Packing 77 is integrally molded from an elastic material such as rubber. Packing 77 has an inner hole of an annular packing main body 79 that is almost completely blocked by multiple flexible pieces 81. Each flexible piece 81 is capable of elastic deformation independently due to radial slits 83.

[0062] The cable 85 that passes through the packing 77 elastically deforms the flexible pieces 81, so that it is sandwiched between the slits 83 and held in the elastically restored state of the flexible pieces 81. As a result, the cable 85 passed through the through hole is supported in the center of the through hole by the packing 77, and the gap between the cable 85 and the inner periphery of the through hole is narrowed by the multiple flexible pieces 81. As a result, the work of blocking the introduction hole drilled in the outer wall 17, for example, the work of sealing, can be omitted, and the installation work of the shutter storage section 15 can be facilitated.

[0063] In the above-described embodiment, the shape of the locking claw 55 is a shape that protrudes upward via the bent portion 56, but the shape of this locking claw 55 may be configured as a T-shape that protrudes downward, to the right, to the left, or to both the left and right. For example, in the case of a locking claw 55 that protrudes downward, the claw receiving groove 61 is shaped to communicate from the upper end of one side portion 63 of the entry hole 57 in a horizontal direction away from the entry hole 57. In other words, the entry hole 57 and the claw receiving groove 61 are in an inverted L shape in a front view. Since the entry hole 57 and the claw receiving groove 61 are in an inverted L shape, the upper edge portion of the claw receiving groove 61 continuing to the upper edge of the entry hole 57 becomes the locking portion 65. Furthermore, in the case where the locking claw 55 protrudes to the right or to the left, the above-mentioned claw receiving groove 61 is unnecessary, and after inserting the locking claw 55 into the entry hole 57, it is slid in the same direction as the locking claw 55 protrudes, for example, to the right if it protrudes to the right, so that the upper corner of one side 63 of the entry hole 57 becomes the locking portion 65, and this locking portion 65 is supported by the edge portion of the bent portion 56 of the locking claw 55. Furthermore, if the shape of the locking claw 55 is a T-shape protruding in both the left and right directions via the bent portion 56, after the locking claw 55 is inserted into the entry hole portion 57, it can slide in either the left or right direction, and by making the upper end corners of the left and right side portions 63 of the entry hole portion 57 into locking portions 65, the bent portion 56 supports the locking portions 65 in either the left or right direction.

[0064] Therefore, according to the mounting structure for the shutter housing section in this embodiment, no space is required in the shutter housing section 15 for raising and lowering it, making it easier to install the shutter housing section 15 on the outer wall 17. [Explanation of symbols]
