Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the above structure of the shutter bracket, when the eaves are close to the upper part of the shutter case, a sufficient working space cannot be secured above the shutter case and the case plate cannot be removed, making maintenance difficult. Also, when the eaves are close above, the winding shaft will be pulled out obliquely downward from the front of the shutter case to the front side. In this case, it is necessary to remove the angle material at the front bottom. However, when both ends of the angle material are fixed from the outside of the bracket, a working space for releasing the fixation is required on the left and right sides of the shutter case. If there are walls or the like close to the left and right sides of the shutter case, a sufficient working space cannot be secured and the angle material cannot be removed. Therefore, in this case as well, maintenance by removing the winding shaft becomes difficult. Furthermore, the left and right brackets may be provided with a portion called a "carrying-out portion" that protrudes inward. A guide member for regulating the position in the thickness direction of the shutter curtain is fixed to this carrying-out portion. In addition to this, both ends of the above-described angle material may be fixed to the carrying-out portion. In such a structure, even if the guide member or the angle material can be removed from the carrying-out portion, this carrying-out portion that protrudes inward from the left and right brackets may become an obstacle, making it difficult to perform maintenance by removing the winding shaft.

[0006] The present invention has been made in view of the above situation, and an object thereof is to provide a structure of an opening / closing body storage portion that can improve workability when performing maintenance by removing a winding portion.

Means for Solving the Problems

[0007] Next, means for solving the above problems will be described with reference to the drawings corresponding to the embodiments. The structure of the opening / closing body storage portion according to claim 1 of the present invention is a structure of an opening / closing body storage portion that houses an opening / closing body 21, The storage portion 17 has an upper cover 39 that covers the upper surface 43 of the storage portion and the upper part 45 of the front of the storage portion, and a lower cover 41 that covers the lower surface 51 of the storage portion and the lower part 53 of the front of the storage portion from the entrance / exit slit 47 through which the opening / closing body 21 enters and exits to the lower front edge 49 of the storage portion, The upper cover 39 and the lower cover 41 are supported by a pair of left and right brackets 13 fixed to the building wall surface 25, A connecting frame 63 that extends along the front edge of the entrance and exit slit 47 and connects the pair of left and right brackets 13; A pair of guide members 67 that are disposed above a pair of left and right guide rails 61 that guide the opening and closing body 21 and regulate the position of the opening and closing body 21 in the thickness direction; A pair of joint members 69 that are fixed to both longitudinal ends of the connecting frame 63 and to which the guide members 67 are respectively fixed, and a support frame body 71 is constituted; The support frame body 71 is characterized in that each of the joint members 69 is detachably fixed to the pair of left and right brackets 13 by fastening members 73 from below.

[0008] In the structure of this opening and closing body storage portion, an opening and closing body 21 that opens and closes an opening 15 of a building is stored in a storage portion 17. The storage portion 17 is covered on the outside by an upper cover 39 and a lower cover 41 that are exterior members. The upper cover 39 and the lower cover 41 are supported by a pair of left and right brackets 13 fixed to the building wall surface 25. The upper cover 39 and the lower cover 41 are separate bodies and can be removed separately. Therefore, when the storage portion 17 is close to the eaves above, maintenance can be performed by removing only the lower cover 41. An entrance and exit slit 47 through which the opening and closing body 21 enters and exits is formed in the lower surface 51 of the storage portion 17. The lower cover 41 covers the lower front portion 53 of the storage portion and the lower surface 51 of the storage portion from the entrance and exit slit 47 to the lower front edge 49 of the storage portion. That is, the side view is L-shaped. Therefore, in the storage portion 17 from which the lower cover 41 has been removed, the lower front portion 53 of the storage portion and the lower surface 51 of the storage portion from the entrance and exit slit 47 to the lower front edge 49 of the storage portion are opened. When the lower cover 41 is removed, the support frame body 71 is exposed. The support frame body 71 is composed of a connecting frame 63, a guide member 67, and a joining member 69. The connecting frame 63 extends along the front edge of the entrance and exit slit 47 and connects a pair of left and right brackets 13. The guide member 67 is disposed above a pair of left and right guide rails 61 and regulates the position of the opening and closing body 21 in the thickness direction. The joining member 69 is fixed to both longitudinal ends of the connecting frame 63, and the guide member 67 is fixed thereto respectively. That is, the connecting frame 63 and the guide member 67 are integrally fixed by the joining member 69. In the support frame body 71, each joining member 69 is detachably fixed to a pair of left and right brackets 13 by fastening members 73 from below. The support frame body 71 exposed by removing the lower cover 41 can be easily removed from the storage portion 17 by releasing the fastening of the fastening members 73 from below. Thereby, different from the conventional structure in which both ends of the connecting frame 63 (conventional angle member) are fixed from the outside of the brackets 13, even when there is no working space for releasing the fixation on the left and right of the storage portion 17, the connecting frame 63 can be easily removed. That is, even when the eaves are close above and walls or the like are close to the left and right of the storage portion 17, the connecting frame 63 can be removed together with the support frame body 71, and the winding portion 57 can be easily pulled out obliquely downward from the lower front portion 53 of the storage portion. Furthermore, in the conventional structure, the guide member 67 that regulates the position of the opening and closing body 21 in the thickness direction was fixed to a portion called a "carrying-out portion" that protrudes inward from the left and right brackets 13. Both ends of the above-described connecting frame 63 were sometimes fixed to this carrying-out portion. In the conventional structure, this carrying-out portion was integrally formed with each bracket 13 by sheet metal processing. Therefore, in the conventional structure, even if the guide member 67 and the angle member can be removed from the carrying-out portion, there is a problem that this carrying-out portion protruding inward from the left and right brackets 13 becomes an obstacle and it is difficult to take out the winding portion 57. On the other hand, in the structure of the opening / closing body storage portion, the joining member 69 of the support frame body 71 in which the connecting frame 63 and the guide member 67 are integrally connected is directly fixed to the bracket 13 where the take-out portion is not formed from below by the fastening member 73. For this reason, in the structure of the opening / closing body storage portion, there is no large protruding portion inside the bracket 13 from which the support frame body 71 has been removed, and the lower front portion 53 of the storage portion is opened with a sufficient working space in the opening width direction.

[0009] The structure of the opening / closing body storage portion according to claim 2 of the present invention is the structure of the opening / closing body storage portion according to claim 1, wherein the connecting frame 63 is a bird damage angle that closes an excess gap formed between the opening / closing body 21 and the entrance / exit slit 47.

[0010] In this structure of the opening / closing body storage portion, the connecting frame 63 is a bird damage angle. The connecting frame 63 originally connects a pair of left and right brackets 13 and has a function as a structural member for increasing the strength of the storage portion 17. Further, the connecting frame 63 is also a part (door stop) against which the door stop piece 65 fixed to the drain slit 23 provided at the lowermost end of the opening / closing body 21 abuts. The connecting frame 63 also has a function as a door stop against which the door stop piece 65 fixed to the opening / closing body 21 abuts in order to prevent the opening / closing body 21 from being further wound around the winding portion 57. Furthermore, this connecting frame 63 forms the front edge of the entrance / exit slit 47 that opens to the lower surface of the storage portion 51. That is, the connecting frame 63 is disposed close to the outdoor side surface of the opening / closing body 21 that enters and exits through the entrance / exit slit 47. This proximity distance is a distance such that the connecting frame 63 does not interfere with the opening / closing body 21 even if displacement due to play in the thickness direction occurs in the opening / closing body 21 whose both side edges are guided by a pair of left and right guide rails 61 and moves up and down. That is, the connecting frame 63 closes the excess gap between the opening / closing body 21. Thereby, it is possible to impart a function of preventing birds from entering the storage portion 17 or getting their feet caught in the gap between the connecting frame 63 and the opening / closing body 21. And since this connecting frame 63 is also integrated with the guide member 67 by the joining member 69 to form the support frame body 71, it can be removed from the bracket 13 together with the guide member 67 and the joining member 69 all at once.

[0011] The structure of the opening / closing body storage part according to claim 3 of the present invention is the structure of the opening / closing body storage part according to claim 1 or 2, characterized in that the support frame body 71 is covered by the lower cover 41.

[0012] In the structure of this opening / closing body storage part, as described above, the support frame body 71 becomes an integrated composite member including the connecting frame 63, the guide member 67, and the joining member 69. That is, the support frame body 71 has a storage part reinforcement function, a door-stop function, and a bird damage prevention function. And only the joining member 69 that connects the guide member 67 and the connecting frame 63 of the support frame body 71 is fixed to the bracket 13 by the fastening member 73. When the lower cover 41 of the storage part 17 is removed, the entire support frame body 71 is exposed, and together with the joining member 69, the fastening member 73 that fixes the joining member 69 to the bracket 13 is exposed on the lower surface 51 of the storage part. Since the storage part 17 is located at the upper edge in the opening of the building, the access for maintenance work is from the lower side. That is, for the operator located below the storage part 17, the fastening release operation of the fastening member 73 and the removal of the support frame body 71 whose fastening has been released can be performed at the closest position.

[0013] The structure of the opening / closing body storage part according to claim 4 of the present invention is the structure of the opening / closing body storage part according to claim 3, characterized in that the support frame body 71 and the lower cover 41 have an integral structure.

[0014] In the structure of this opening / closing body storage section, a support frame body 71 in which a guide member 67 and a connecting frame 63 are connected by a joining member 69 may further be an integrated member with the lower cover 41. In this support frame body 71 with the lower cover, the upper edge of the lower cover 41 is connected to the lower edge of the upper cover 39 by a fastening member 73. The lower cover 41 is such that the joining member 69 of the integrated support frame body 71 is fixed to the bracket 13. In the structure of this opening / closing body storage section, when a member of the support frame body 71 with the cover is removed from the storage section 17, the lower part 53 of the front of the storage section will be opened with sufficient working space in the opening width direction.

Effect of the Invention

[0015] According to the structure of the opening / closing body storage section described in claim 1 of the present invention, in high-place work, maintenance work can be performed more easily from diagonally below while ensuring a sufficient working opening without creating obstructive protruding parts, so the workability when removing the winding section for maintenance can be improved.

[0016] According to the structure of the opening / closing body storage section described in claim 2 of the present invention, a pair of left and right brackets are connected to enhance the strength of the storage section, and the connecting frame, which is also a door-stop member for abutting the door-stop piece, also functions as a bird damage angle for preventing birds from entering through the entrance / exit slit. Since the connecting frame in which these functions are integrated can be removed from the bracket together with the guide member and the joining member, the workability during maintenance can be improved.

[0017] According to the structure of the opening / closing body storage section described in claim 3 of the present invention, since a support frame body with an integrated structure including a connecting frame, a guide member, and a joining member is covered by the lower cover, by removing the lower cover from the front, the support frame body is exposed, and at the same time, by releasing the fastening of the fastening member that fixes the joining member of the exposed support frame body and the bracket from below, the storage section can be largely opened so that the winding section can be taken out with only the removal of two members, and the workability during maintenance can be improved.

[0018] According to the structure of the opening / closing body storage part described in claim 4 of the present invention, since the support frame body and the lower cover have an integral structure, the storage part can be greatly opened with the winding part being removable by easily removing only one member, and the workability during maintenance can be improved.

Embodiments for Carrying Out the Invention

[0020] Hereinafter, embodiments according to the present invention will be described with reference to the drawings. FIG. 1 is a side view of the shutter device 11 with the structure of the opening / closing body storage part according to the present embodiment, seen with one of the brackets 13 omitted. The structure of the opening / closing body storage part according to this embodiment is applied to the shutter device 11. In the shutter device 11, an opening / closing body that opens and closes the building opening 15 is drawn out and wound up by a box-shaped storage part 17 fixed to the building body. The opening / closing body is a shutter curtain 21 in which a plurality of slats 19 (see FIG. 3) made of aluminum or steel are connected in the direction in which they are drawn out and wound up. The shutter curtain 21 has a drain slat 23 (see FIG. 3) at the tip in the drawing-out direction, that is, at the lower end when fully closed.

[0021] The storage part 17 has a pair of support plates 27 (also see FIG. 9) fixed to the building wall surface 25 above the building opening 15. The support plates 27 are formed in a vertically long strip shape and are arranged in parallel on both sides sandwiching the building opening 15. On the surface of each support plate 27, a plurality of bracket locking claws 29 protruding upward are formed, for example, at two locations, upper and lower. At the upper ends of the pair of left and right support plates 27, an upper frame 31 that is long in the opening width direction of the building opening 15 abuts and is fixed to the building wall surface 25.

[0022] A pair of left and right brackets 13 are fixed to each support plate 27. The bracket 13 is formed of a square sheet metal material in which a flange portion is bent from each side portion toward the facing surface side. The bracket 13 has a locking portion 33 (see FIG. 9) with a cutout in the rear flange portion, and this locking portion 33 is locked to the bracket locking claw 29 of the support plate 27 and supported by the building wall surface 25 (see FIG. 9). The pair of left and right brackets 13 are connected at the inner side of the lower part by a trough 35 that is long in the opening width direction. The trough 35 is fixed to the building wall surface 25. A decorative side plate 37 (see FIG. 2) that covers the bracket 13 is attached to the outside of the pair of left and right brackets 13.

[0023] The storage part 17 has a frame part composed of the support plates 27, the upper frame 31, the brackets 13, and the trough 35 as an outer shell and is fixed to the building wall surface 25.

[0024] The storage part 17 is covered by the frame part with an upper cover 39 and a lower cover 41. The upper cover 39 and the lower cover 41 are supported by a pair of left and right brackets 13 fixed to the building wall surface 25. The upper cover 39 covers the upper surface 43 of the storage part and the upper part 45 of the front of the storage part. The upper cover 39 is removably fixed to the upper frame 31 and the bracket 13 by a fastening member (not shown). For the fastening member, for example, screws, bolts or nuts can be used. In the structure of the opening / closing body storage part, in order to obtain water tightness, the edge (vertical edge part) of the decorative side plate 37 in contact with the building wall surface 25 and the upper edge of the upper cover 39 are filled with a gap by water stop caulking against the building wall surface 25.

[0025] The lower cover 41 covers the lower surface 51 of the storage part and the lower part 53 of the front of the storage part from the entrance / exit slit 47 through which the shutter curtain 21 enters and exits to the front lower edge 49 of the storage part. The lower cover 41 is removably fixed to the bracket 13 by a fastening member. Also, the lower edge of the upper cover 39 and the upper edge of the lower cover 41 are removably fixed by a fastening member (not shown) screwed from the front side of the storage part 17 to a co-fastening member 55 provided on the back. Since the fastening member screwed to the co-fastening member 55 co-fastens the upper cover 39 and the lower cover 41, by removing this, only the lower cover 41 can be removed leaving the upper cover 39.

[0026] The storage part 17 houses a winding part 57 inside. The winding part 57 has both end shaft parts rotatably supported by bearing parts 59 provided on the opposing surfaces of a pair of left and right brackets 13. The bearing part 59 has an opening part that allows the shaft part to be attached and detached obliquely from above. The winding part 57 can be removed during maintenance after the storage part 17 is installed by removing the shutter curtain 21 and once lifting the shaft part upward and detaching it from this opening part.

[0027] The leading end (upper end) of the shutter curtain 21 in the winding direction is connected to the winding unit 57. The winding unit 57 can feed out and wind up the shutter curtain 21 from the entrance / exit slit 47 of the storage unit 17 by being rotated by an opening / closing mechanism (not shown). The shutter curtain 21 is located below the entrance / exit slit 47, and both side edges are guided by a pair of parallel guide rails 61 provided vertically on the left and right of the building opening 15, and the shutter curtain 21 moves up and down the building opening 15. Thereby, the shutter curtain 21 can open and close the building opening 15.

[0028] FIG. 2 is an exploded perspective view of the storage unit 17. The storage unit 17 has a connecting frame 63 that extends along the front edge of the entrance / exit slit 47 and connects a pair of left and right brackets 13. The connecting frame 63 is made of, for example, an aluminum profile, and by being fixed across the pair of brackets 13, it becomes a structural member that enhances the strength of the storage unit 17. Further, the connecting frame 63 extends along the entrance / exit slit 47 of the shutter curtain 21 and forms the front edge of the entrance / exit slit 47.

[0029] In the present embodiment, the connecting frame 63 also functions as a bird protection angle. The bird protection angle closes the excess gap formed between the shutter curtain 21 and the entrance / exit slit 47, and has a shape with a predetermined thickness and extending in the depth direction of the entrance / exit slit 47. In the present embodiment, by being formed in a polygonal pipe shape, it prevents birds from entering the storage unit 17 or getting caught in the gap between the connecting frame 63 and the shutter curtain 21 and stopping.

[0030] FIG. 3 is a perspective view of the main part of the shutter device 11 showing the shutter curtain 21 to which the door stop piece 65 is attached. The door stop piece 65 of the shutter curtain 21 that is guided by the guide rail 61 and rises (is wound up) abuts against the connecting frame 63 that forms the front edge of the entrance and exit slit 47. The door stop piece 65 is fixed to the slat 19 or the drain slat 23 at the leading end in the pay-out direction of the shutter curtain 21 or the like. The door stop piece 65 is provided close to the pair of left and right guide rails 61 and abuts against the connecting frame 63 to regulate the further winding of the shutter curtain 21 into the storage part 17.

[0031] As shown in FIG. 2, guide members 67 are fixed to both sides in the longitudinal direction of the connecting frame 63. The connecting frame 63 and the guide members 67 are integrally fixed by a joining member 69 that joins both of them.

[0032] FIG. 4 is a front view of the storage part 17 with the interior covered by the upper cover 39 and the lower cover 41 represented by a broken line. Each guide member 67 is disposed above the pair of left and right guide rails 61 that guide the shutter curtain 21. The guide member 67 is in sliding contact with the outdoor side surface (front surface) of the shutter curtain 21 to regulate the position of the shutter curtain 21 in the thickness direction (left and right direction in FIG. 1) as shown in FIG. 1. That is, the guide member 67 has a function for changing the lifting position of the shutter curtain 21. The structure of the opening / closing body storage part realizes moving the position of the shutter curtain 21 at the time of closing closer to the building side by regulating the position of the shutter curtain 21 at the time of pay-out and winding-up to be closer to the winding center side than the tangential direction of the winding part 57.

[0033] FIG. 5 is a front view of the support frame body 71. The guide member 67 is fixed to both sides in the longitudinal direction of the connecting frame 63 via the joining member 69. That is, the joining member 69 is fixed to both ends in the longitudinal direction of the connecting frame 63, and the guide members 67 are fixed thereto respectively. The connecting frame 63, the joining member 69, and the guide member 67 constitute the support frame body 71. The guide member 67 is screwed to the joining member 69 by a fastening member 73 that is inserted through the front of the joining member 69.

[0034] The storage unit 17 will be covered by an upper cover 39 and a lower cover 41 as shown in FIG. 4, with a frame body portion composed of a support plate 27, an upper frame 31, a bracket 13, and a lower frame 35, a winding portion 57, and a support frame body 71.

[0035] FIG. 6 is an enlarged perspective view of the vicinity of the joining member at one end of the support frame body 71. The joining member 69 has a horizontal substrate portion 75 that is rectangular in plan view and long in the longitudinal direction of the connecting frame 63. On one short side portion of the horizontal substrate portion 75, a connecting frame fixing plate portion 77 bent at a right angle upward is formed. In the connecting frame fixing plate portion 77, a plurality (for example, two spaced apart front and back) of screw fixing holes 79 (see FIG. 7) into which a fastening member 73 is inserted from the substrate portion side are formed. On one long side portion of the horizontal substrate portion 75, a guide member fixing plate portion 81 bent at a right angle upward is formed. In the guide member fixing plate portion 81, one screw fixing hole 79 (see FIG. 7) into which a fastening member 73 is inserted from the substrate portion side is formed. The guide member fixing plate portion 81 may be formed with a plurality of positioning holes 85 (see FIG. 7) into which positioning protrusions 83 (see FIG. 7) provided on the guide member 67 fit around the screw fixing hole 79.

[0036] FIG. 7 is an exploded perspective view of the support frame body 71 shown in FIG. 6. For the joining member 69, the fastening member 73 inserted through the screw fixing hole 79 of the connecting frame fixing plate portion 77 is screwed into a fixing groove 87 formed at the end of the connecting frame 63. Also, for the joining member 69, the fastening member 73 inserted through the screw fixing hole 79 of the guide member fixing plate portion 81 is screwed into a screw fixing boss 91 provided on the back surface opposite to the guide surface 89 of the guide member 67. The guide member 67 is provided with a positioning protrusion 83 that fits into the positioning hole 85 in the vicinity of the screw fixing boss 91.

[0037] The joining member 69 that fixes the connecting frame 63 and the guide member 67 has two bracket fixing holes 93 formed at intervals in the front-rear direction on the short side portion of the horizontal substrate portion 75 on the side opposite to the connecting frame fixing plate portion 77. The support frame body 71 formed by fixing the connecting frame 63 and the guide member 67 integrally with the joining member 69 has a fastening member 73 inserted downward through the bracket fixing hole 93 detachably fixed to the support frame body fixing holes 95 (see FIG. 9) in the pair of left and right brackets 13.

[0038] In the structure of the opening / closing body storage portion, the door stop piece 65 hits the connecting frame 63, and the hitting direction of the door stop piece 65 and the fastening direction of the fastening member 73 that fixes the bracket fixing hole 93 to the bracket 13 are the same direction. This makes it difficult for the fixing of the joining member 69 and the bracket 13 to become loose. If the bracket fixing hole 93 is screwed by the fastening member 73 from above, it will be easy to come off downward. In contrast, in the structure of the opening / closing body storage portion, the screwing direction of the fastening member 73 becomes a force that presses the bracket 13 from below, and the joining member 69 can be made difficult to come off.

[0039] Next, the maintenance procedure when the winding portion 57 of the shutter device 11 is removed will be described.

[0040] FIG. 8 is an exploded perspective view of the main part of the storage portion 17 with the lower cover 41 removed. During maintenance for removing the winding portion 57, first, the lower cover 41 is removed from the storage portion 17. The lower cover 41 is removed by unscrewing the fastening member that fixes the lower edge of the upper cover 39 and the upper edge of the lower cover 41 from the co-fastening member 55. When the lower cover 41 is removed from the storage portion 17, the lower front part 53 of the storage portion and the front side of the lower surface 51 of the storage portion are opened.

[0041] FIG. 9 is an exploded perspective view of the main part of the storage portion 17 with the support frame body 71 removed. When the lower cover 41 is removed, the storage unit 17 allows the support frame body 71 to be removed. At this time, whether the upper cover 39 is removed or not, the support frame body 71 can be removed. When the lower cover 41 is removed from the storage unit 17, the joining members 69 at both longitudinal ends of the support frame body 71 are exposed. The support frame body 71 can be removed by disengaging the fastening member 73 that is inserted through the horizontal substrate portion 75 of the joining member 69 and screwed into the support frame body fixing hole 95 of the bracket 13.

[0042] FIG. 10 is an exploded perspective view of the main part of the storage unit 17 with the winding unit 57 removed. When the lower cover 41 and the support frame body 71 are removed from the storage unit 17, the lower front part 53 of the storage unit front and the lower surface 51 of the storage unit from the entrance and exit slit 47 to the lower front edge 49 of the storage unit open widely. By putting a hand through this opening part, the winding unit 57 can be removed from the bearing part 59 and removed from the outside obliquely below the storage unit 17. Note that, for the removal of the winding unit 57, the shutter curtain 21 needs to be removed from the winding unit 57 in advance.

[0043] In the above embodiment, the configuration in which the lower cover 41 and the support frame body 71 are separate bodies has been described. However, the structure of the opening / closing body storage unit may be such that the support frame body 71 and the lower cover 41 are an integral structure. In this modification, the number of parts of the storage unit 17 is reduced, and the work of removing and attaching members during maintenance is also reduced.

[0044] Next, the operation of the above-described configuration will be described.

[0045] In the structure of the opening / closing body storage part according to this embodiment, a shutter curtain 21 for opening and closing an opening of a building is stored in a storage part 17. The storage part 17 is covered on the outside by an upper cover 39 and a lower cover 41 which are exterior members. The upper cover 39 and the lower cover 41 are supported by a pair of left and right brackets 13 fixed to a building wall surface 25. The upper cover 39 and the lower cover 41 are separate bodies and can be removed separately. Therefore, when the storage part 17 is close to the eaves above, maintenance can be performed by removing only the lower cover 41.

[0046] An entrance / exit slit 47 through which the shutter curtain 21 enters and exits is formed in the lower surface 51 of the storage part 17 of the storage part. The lower cover 41 covers the lower front part 53 of the storage part front and the lower surface 51 of the storage part from the entrance / exit slit 47 to the front edge 49 of the lower part of the storage part. That is, it is L-shaped in side view. Therefore, in the storage part 17 from which the lower cover 41 is removed, the lower front part 53 of the storage part and the lower surface 51 of the storage part from the entrance / exit slit 47 to the front edge 49 of the lower part of the storage part will be opened.

[0047] When the lower cover 41 is removed from the storage part 17, the support frame body 71 is exposed. The support frame body 71 is composed of a connecting frame 63, a guide member 67, and a joining member 69. The connecting frame 63 extends along the front edge of the entrance / exit slit 47 and connects a pair of left and right brackets 13. The guide member 67 is disposed above a pair of left and right guide rails 61 and regulates the position of the shutter curtain 21 in the thickness direction. The joining member 69 is fixed to both longitudinal ends of the connecting frame 63, and the guide member 67 is fixed to each of them. That is, the connecting frame 63 and the guide member 67 are integrally fixed by the joining member 69.

[0048] In the support frame body 71, each joining member 69 is detachably fixed to a pair of left and right brackets 13 by fastening members 73 from below. The support frame body 71 exposed by removing the lower cover 41 can be easily removed from the storage part 17 by releasing the fastening of the fastening members 73 from below.

[0049] Thus, unlike the conventional structure in which both ends of the connecting frame 63 (conventional angle material) are fixed from the outside of the bracket 13, even when there is no working space for fixing release on the left and right sides of the storage part 17, the connecting frame 63 can be easily removed. That is, even when the eaves are close above and walls or the like are close on the left and right sides of the storage part 17, the connecting frame 63 can be removed together with the support frame body 71, and the winding part 57 can be easily pulled out obliquely downward from the lower front part 53 of the storage part.

[0050] Furthermore, in the conventional structure, the guide member 67 that regulates the position of the shutter curtain 21 in the thickness direction was fixed to a part called the "take-out part" that protrudes inward from the left and right brackets 13. Both ends of the above-mentioned connecting frame 63 were sometimes fixed to this take-out part. In the conventional structure, this take-out part was integrally formed with each bracket 13 by sheet metal processing.

[0051] Therefore, in the conventional structure, even if the guide member 67 and the angle material can be removed from the take-out part, this take-out part that protrudes inward from the left and right brackets 13 becomes an obstacle, and there is a problem that it is difficult to take out the winding part 57.

[0052] On the other hand, in the structure of the opening / closing body storage part, the joining member 69 of the support frame body 71 that integrally connects the connecting frame 63 and the guide member 67 is directly fixed from below with a fastening member 73 to the bracket 13 where the take-out part is not formed. Therefore, in the structure of the opening / closing body storage part, there is no large protruding part inside the bracket 13 from which the support frame body 71 has been removed, and the lower front part 53 of the storage part is opened with a sufficient working space in the opening width direction.

[0053] Also, for the storage part 17, the edge of the decorative side plate 37 and the upper edge of the upper cover 39 are filled with a gap with a water stop caulking against the building wall surface 25. In the structure of the opening / closing body storage part, since the winding part 57 can be taken out without removing the decorative side plate 37 or the upper cover 39, it is not necessary to incur the labor, time, and cost of removing the water stop treatment and performing the water stop caulking treatment and construction again during reassembly.

[0054] Note that in the structure of the opening / closing body storage part, simple maintenance such as applying oil or looking into the storage part may be performed by removing only the lower cover 41 without removing the winding part 57. Even in this case, since it is not necessary to remove the decorative side plate 37 or the upper cover 39, the labor of removing the water stop treatment and the labor, time, and cost of performing the water stop caulking treatment / construction again during reassembly can be saved.

[0055] Also, in the structure of this opening / closing body storage part, the connecting frame 63 is a bird guard angle. The connecting frame 63 originally has a function as a structural member that connects a pair of left and right brackets 13 and enhances the strength of the storage part 17. Further, the connecting frame 63 is also a part (door stop) against which a door stop piece 65 fixed to the water drainage slat 23 provided at the lowermost end of the shutter curtain 21 abuts. The connecting frame 63 also has a function as a door stop against which the door stop piece 65 fixed to the shutter curtain 21 abuts to prevent the shutter curtain 21 from being further wound around the winding part 57.

[0056] Furthermore, this connecting frame 63 forms the front edge of the entrance / exit slit 47 that opens to the lower surface 51 of the storage part. That is, the connecting frame 63 is disposed close to the outdoor side surface of the shutter curtain 21 that enters and exits through the entrance / exit slit 47.

[0057] This proximity distance is a distance such that the connecting frame 63 does not interfere with the shutter curtain 21 even if displacement due to play in the thickness direction occurs in the shutter curtain 21 that is guided by the left and right pair of guide rails 61 and moves up and down. That is, the connecting frame 63 fills the surplus gap between the shutter curtain 21. Thereby, a function of preventing a bird from entering the storage part 17 or getting its foot caught in the gap between the connecting frame 63 and the shutter curtain 21 can be imparted.

[0058] And since this connecting frame 63 is integrated with the guide member 67 by the joint member 69 to form the support frame body 71, it can be removed from the bracket 13 together with the guide member 67 and the joint member 69. As a result, the left and right pair of brackets 13 are connected to enhance the strength of the storage portion 17, and the connecting frame 63, which is also a contact member for abutting the door stop piece 65, also functions as a bird damage angle for preventing the intrusion of birds from the entrance and exit slit 47. Since the connecting frame 63 that aggregates these functions can be removed from the bracket 13 together with the guide member 67 and the joint member 69, the workability during maintenance can be improved.

[0059] In the structure of this opening and closing body storage portion, as described above, the support frame body 71 becomes an integrated composite member including the connecting frame 63, the guide member 67, and the joint member 69. That is, the support frame body 71 has a storage portion reinforcement function, a door contact function, and a bird damage suppression function. And only the joint member 69 that connects the guide member 67 and the connecting frame 63 of the support frame body 71 is fixed to the bracket 13 by the fastening member 73.

[0060] When the lower cover 41 of the storage portion 17 is removed, the entire support frame body 71 is exposed, and together with the joint member 69, the fastening member 73 that fixes the joint member 69 to the bracket 13 is exposed on the lower surface 51 of the storage portion. Since the storage portion 17 is located at the upper edge of the opening in the building, the access for maintenance work is from the lower side.

[0061] That is, for an operator positioned below the storage unit 17, the fastening member 73 can be unfastened and the support frame body 71 with the fastening released can be removed at the closest position. As a result, the support frame body 71 having an integrated structure including the connecting frame 63, the guide member 67, and the joining member 69 is covered by the lower cover 41. By removing the lower cover 41 from the front, the support frame body 71 is exposed, and at the same time, by unfastening the fastening member 73 that fixes the joining member 69 of the support frame body 71 and the bracket 13 exposed from below, the winding unit 57 can be easily removed and the storage unit 17 can be greatly opened, improving the workability during maintenance.

[0062] Also, in the structure of this opening / closing body storage unit, the support frame body 71 in which the guide member 67 and the connecting frame 63 are connected by the joining member 69 may further be an integrated member with the lower cover 41. In the support frame body 71 with a lower cover according to this modification, the upper edge of the lower cover 41 is connected to the lower edge of the upper cover 39 by the fastening member 73. The lower cover 41 has the joining member 69 of the integrated support frame body 71 fixed to the bracket 13.

[0063] In the structure of the opening / closing body storage unit according to this modification, when a member of the support frame body 71 with a cover is removed from the storage unit 17, the lower part 53 of the front of the storage unit is opened with a sufficient working space in the opening width direction. As a result, since the support frame body 71 and the lower cover 41 have an integrated structure, the winding unit 57 can be easily removed and the storage unit 17 can be greatly opened, improving the workability during maintenance with the easy removal of only one member.

[0064] Therefore, according to the structure of the opening / closing body storage unit according to the present embodiment, in high-place work, an easy maintenance work can be performed from diagonally below while ensuring a sufficient working opening without creating an obstructive protruding part, improving the workability when removing the winding unit 57 for maintenance.
