Description

Technical Field

[0001] The present invention relates to an attachment structure for an opening / closing body storage portion and a construction method for an opening / closing body storage portion.

Background Art

[0002] For a window shutter which is an opening / closing body device, a storage portion capable of winding up a shutter curtain which is an opening / closing body is attached to a building wall above an opening. The storage portion extends in the width direction of the opening and is attached to the building wall by mounting brackets that support both longitudinal ends. The mounting brackets are formed, for example, in a substantially plate shape that is long in the vertical direction, and are attached to the building wall so as to further extend upward a pair of left and right guide rail frames (vertical frames) that sandwich the opening in the width direction and are attached to the building wall (see, for example, Patent Documents 1 and 2). In this attachment structure, the upper end of the vertical frame serves as a reference for the attachment position, and the storage portion is attached.

[0003] On the other hand, in the attachment structure of the opening / closing body storage portion, there is one in which a mounting bracket is attached with a horizontal batten provided in advance above the opening as a reference for the attachment position. In this attachment structure, a stepped portion having a convex cross-section is formed along the longitudinal direction of the batten on the upper surface of the batten perpendicular to the building wall. Linear marks perpendicular to the building wall are provided at both longitudinal ends of the stepped portion. The mounting bracket has a support arm that supports this bracket in parallel with a bracket perpendicular to the building wall of the storage portion. The support arm has a substrate portion that bends parallel to the building wall. The substrate portion has a horizontal piece portion that bends perpendicular to the building wall from the lower end, and a hanging piece portion that bends parallel to the building wall and hangs down from the front end of this horizontal piece portion. And a linear mark extending in the vertical direction is provided on the front surface of the hanging piece portion.

[0004] The installation procedure for the opening / closing mechanism storage unit using this mounting structure involves placing the lower end of the hanging piece against the upper surface of the lintel at one end in the longitudinal direction of the lintel. Next, while keeping the mounting bracket against the upper surface, slide it along the longitudinal direction of the lintel until the mark on the stepped section and the mark on the hanging piece visually align. Once the positioning is complete, fix the mounting bracket, which is being held by hand, to the building wall with screws or the like. Similarly, fix the mounting bracket at the other end in the longitudinal direction. Finally, insert the storage unit between the left and right mounting brackets attached to the building wall, and complete the installation by engaging the engaging parts of each support arm with the engaged parts provided on the bracket of the storage unit to support the storage unit to the building wall. [Prior art documents] [Patent Documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 2000-110460 [Patent Document 2] Japanese Utility Model Publication No. 3-120796 [Overview of the project] [Problems that the invention aims to solve]

[0006] However, the conventional mounting structure for the opening / closing mechanism aligns the mounting bracket vertically by placing the hanging piece of the mounting bracket against the lintel, and aligns the mounting bracket horizontally by visually matching the marks on the lintel and the hanging piece. Therefore, vertical alignment is achieved by "touching" the lower end of the hanging piece against the upper surface of the lintel, which does not result in stable contact between two flat surfaces and is prone to misalignment. Furthermore, regarding left-right alignment, the accuracy varied depending on the worker, as the alignment was performed while visually checking the marks. Furthermore, the mounting bracket is formed in a crank shape in side view by being bent twice by a horizontal piece that bends perpendicularly to the building wall from the lower end of the base plate and a hanging piece that bends parallel to the building wall from the front end of the horizontal piece, with the lower end of the hanging piece being the contact point with the lintel. Therefore, if there is variation in the two bending angles, the mounting bracket with the lower end of the hanging piece in contact with the lintel may have an error in its overall height from the lintel, and if there is a difference in the bending angles of the left and right mounting brackets, the storage unit may not be supported horizontally even if the lintel is horizontal.

[0007] The present invention has been made in view of the above circumstances, and its purpose is to provide a mounting structure for an opening / closing body housing and a method for constructing an opening / closing body housing that allows the support plate for attaching the opening / closing body housing to be fixed with minimal error using simple work. [Means for solving the problem]

[0008] Next, means for solving the above-mentioned problems will be described with reference to drawings corresponding to the embodiments. The mounting structure for the opening / closing body storage section according to claim 1 of the present invention is a mounting structure for the opening / closing body storage section in which a support plate 23 is attached to the building wall 17 based on a lintel 31 provided in the opening 19, and a storage section 13 capable of accommodating the opening / closing body is supported on the support plate 23, The lintel 31 has a base portion 39 that extends horizontally for a predetermined length from the building wall 17 and on which the support plate 23 is placed, and a notched edge 47 adjacent to the base portion 39 and located for a predetermined length C from the edge 43 of the lintel 31 and perpendicular to the building wall 17. The support plate 23 is characterized by comprising a horizontal mounting portion 63 that rests on the seat portion 39, and a hanging portion 65 that curves from the front edge of the mounting portion 63, hangs down from the front edge of the seat portion 39, and whose side portion 67 abuts against the notched edge 47.

[0009] In this mounting structure for the opening / closing storage section, a seat portion 39 is formed on the lintel 31 provided in the opening 19 on which a support plate 23 can be placed. The support plate 23 has a horizontal mounting portion 63 that rests on this seat portion 39. The support plate 23 is positioned vertically as an attachment point to the building wall 17 by the mounting portion 63 being placed on the seat portion 39 of the lintel 31. Once the support plate 23 is positioned vertically by the mounting portion 63 being placed on the seat portion 39, it slides toward the center of the lintel 31 while remaining on the seat portion 39, causing the side portion 67 of the hanging portion 65 that curves and hangs down from the front edge of the mounting portion 63 to come into contact with the notched edge 47 adjacent to the seat portion 39. In other words, the sliding of the support plate 23 is restricted by the hanging portion 65 coming into contact with the notched edge 47. As a result, the support plate 23 is positioned horizontally as the mounting position to the building wall 17 at a notched edge 47 provided at a predetermined length C from the edge 43 of the lintel 31. In this mounting structure for the opening / closing body storage section, the mounting part 63 is placed in contact with the base part 39, so the vertical position of the support plate 23 can be fixed in a stable contact state. That is, the support plate 23 does not tilt in the front, back, left, or right directions. Furthermore, by sliding the support plate 23 while it is placed on the base part 39, the side part 67 of the hanging piece 65 that hangs down from the mounting part 63 comes into contact with the notched edge 47, so the horizontal position of the support plate 23 can be fixed in a stable contact state. In other words, the position in the vertical, horizontal, and right directions is determined by bringing them into contact with each other. Therefore, compared to conventional positioning work that involves aligning two marks by visual inspection, the proportion of work that depends on the worker's skill, such as visual inspection, is reduced, and variations in accuracy can be suppressed.

[0010] The mounting structure for the opening / closing body housing according to claim 2 of the present invention is the mounting structure for the opening / closing body housing according to claim 1, The lintel 31 connects the upper ends of a pair of left and right vertical frames 29 that are attached to the building wall 17, sandwiching the opening 19 in the width direction. The seat portion 39 is characterized in that it is located at the end portion 32 of the lintel 31, which is located above the vertical frame 29.

[0011] In this mounting structure for the opening / closing mechanism storage unit, the lintel 31 is provided by connecting the upper ends of a pair of left and right vertical frames 29 that are attached to the building wall 17, sandwiching the opening 19 in the width direction. As a result, the lintel 31 is fixed horizontally to the building wall 17 above the opening 19. The lintel 31 has seat portions 39 formed at both ends 32 in the longitudinal direction on which a support plate 23 can be placed. In other words, the support plate 23 is positioned above the vertical frames 29 via the ends 32 of the lintel 31.

[0012] The mounting structure for the opening / closing body housing according to claim 3 of the present invention is the mounting structure for the opening / closing body housing according to claim 1 or 2, The support plate 23 comprises a base plate 61 attached along the building wall 17, and a support arm 51 provided on the base plate 61 to support the storage section 13. The mounting portion 63 is characterized in that it extends perpendicularly from the lower end of the base plate 61 to the building wall 17, and the hanging portion 65 is formed by curving parallel to the building wall 17 from the front edge of the mounting portion 63 opposite to the building wall 17.

[0013] In this mounting structure for the opening and closing storage section, the mounting portion 63 of the support plate 23, which rests on the seat portion 39 of the lintel 31, can be formed by bending the base plate 61 once. Compared to the conventional structure in which the lower end of a hanging piece formed in a crank shape in side view by bending it twice contacts the lintel 31, the effect of variations in the bending angle can be halved. This suppresses errors in the overall height of the support plate 23 from the lintel 31. In other words, the horizontal accuracy of the storage section 13, which is supported on both sides by the support plate 23, can be improved.

[0014] The mounting structure for the opening / closing body housing described in claim 4 of the present invention is the mounting structure for the opening / closing body housing described in claim 3, The support arm 51 is characterized by having an engaging portion 55 protruding from its upper edge, which engages with the bracket 21 of the storage portion 13.

[0015] In this mounting structure for the opening / closing storage unit, an engaging portion 55 is provided protruding from the support arm 51, such as being formed in a convex shape. The engaging portion 55 engages with an engaged portion 57 provided on the bracket 21 of the storage unit 13. The storage unit 13 is positioned and placed on the support plate 23, and the bracket 21 of the storage unit 13 engages with the engaging portion 55, so that the mounting state with the support plate 23 is not just a resting state but an engaged state, thereby attaching the storage unit 13 to the building wall 17 via the support plate 23.

[0016] The mounting structure for the opening / closing body housing according to claim 5 of the present invention is the mounting structure for the opening / closing body housing according to claim 1 or 2, The lintel 31 is characterized in that a cable passage recess 49 is formed in the vicinity of the seat portion 39 and closer to the center of the lintel 31 than the notched edge 47.

[0017] In this mounting structure for the opening / closing storage unit, a cable passage recess 49 is provided near the base portion 39 of the lintel 31. The cable passage recess 49 is formed, for example, by cutting out a concave shape from the front end of the base portion 39 on the side opposite the building wall 17 toward the building wall 17. The cable 73 pulled out from the building wall 17 can be routed along the underside of the base portion 39 along the lintel 31 by passing it through this cable passage recess 49, and then pulled out to the outside from the end portion 32 of the lintel 31. In other words, a part of the lintel 31 is used as a wiring duct. With the cable 73 pulled out, the storage unit 13 rests on top of the base portion 39 of the lintel 31. Since the cable 73 is routed along the underside of the base portion 39, it does not interfere with the storage unit 13. The storage unit 13, which rests on the base portion 39, is supported by support plates 23 at both sides by brackets 21. The storage unit 13, installed in this manner, covers the cable exit hole 71 in the building wall 17 from the back. The cable 73 pulled out from the end 32 of the lintel 31 is either pulled into the storage unit 13 and connected, or passed through the vertical frame 29, so that it is not exposed to the outside.

[0018] The mounting structure for the opening / closing body housing described in claim 6 of the present invention is the mounting structure for the opening / closing body housing described in claim 3, The brazier 31 is characterized in that a cable passage recess 49 is formed near the seat portion 39 and closer to the center of the brazier 31 than the cut side 47.

[0019] In the attachment structure of this opening / closing body storage portion, the action is the same as that of claim 5.

[0020] The attachment structure of the opening / closing body storage portion according to claim 7 of the present invention is the attachment structure of the opening / closing body storage portion according to claim 4, The brazier 31 is characterized in that a cable passage recess 49 is formed near the seat portion 39 and closer to the center of the brazier 31 than the cut side 47.

[0021] In the attachment structure of this opening / closing body storage portion, the action is the same as that of claim 5.

[0022] The construction method of the opening / closing body storage portion according to claim 8 of the present invention is a construction method of an opening / closing body storage portion in which a support plate 23 is attached to a building wall 17 based on a brazier 31 provided in an opening 19, and a storage portion 13 capable of accommodating an opening / closing body is supported by the support plate 23, a step of placing a placement portion 63 provided on the support plate 23 on a seat portion 39 provided on the brazier 31 and extending horizontally from the building wall 17; a step of sliding the placement portion 63 along the longitudinal direction of the brazier 31 while the placement portion 63 is placed on the seat portion 39, and bringing a side portion 67 of a hanging piece portion 65 hanging from the front edge of the placement portion 63 into contact with a cut side 47 that is adjacent to the seat portion 39 and is located at a predetermined length C from an edge 43 of the brazier 31 and perpendicular to the building wall 17; characterized by including the above.

[0023] In this construction method for the opening / closing storage section, the mounting portion 63 of the support plate 23 is placed on the seat portion 39 provided on the lintel 31 located in the opening 19. The support plate 23 is positioned vertically by the mounting portion 63 resting on the horizontal seat portion 39 of the lintel 31. With the support plate 23 positioned vertically by the mounting portion 63 resting on the seat portion 39, it slides along the longitudinal direction of the lintel 31 while remaining on the seat portion 39. As the support plate 23 slides, the side portion 67 of the hanging piece portion 65 that curves and hangs down from the front edge of the mounting portion 63 comes into contact with the notched edge 47 at a predetermined distance C from the edge 43 of the lintel 31. In other words, the sliding of the support plate 23 is restricted by the hanging piece portion 65 contacting the notched edge 47. As a result, the support plate 23 is positioned horizontally. In this method of constructing the opening / closing storage unit, the mounting portion 63 is placed in contact with the base portion 39, allowing the support plate 23 to be positioned in a stable contact state in the vertical direction. That is, the support plate 23 does not tilt in the front, back, left, or right directions. Furthermore, by sliding the support plate 23 while it is placed on the base portion 39, the side portion 67 of the hanging piece portion 65 that hangs down from the mounting portion 63 is brought into contact with the cut edge 47, allowing the support plate 23 to be positioned in a stable contact state in the left and right directions and at a distance C from the lintel edge 43. Therefore, compared to conventional positioning work that involves aligning two marks by eye, the proportion of work that depends on the worker's skill is reduced, and variations in accuracy can be suppressed. The storage unit 13 is then attached horizontally to the building wall 17 along the lintel 31 via the support plate 23 without tilting.

[0024] The method for constructing an opening / closing body storage section according to claim 9 of the present invention is a method for constructing an opening / closing body storage section in which a support plate 23 is attached to a building wall 17 based on a lintel 31 provided in an opening 19, and a storage section 13 capable of accommodating an opening / closing body is supported on the support plate 23, The process involves attaching a pair of left and right vertical frames 29 to the building wall 17 at the same height, sandwiching the opening 19 in the width direction. The process involves connecting the upper ends of the vertical frames 29 with the lintel 31 and fixing the lintel 31 to the building wall 17, The process involves placing the mounting portion 63 provided on the support plate 23 onto the seat portion 39 provided on the lintel 31 and extending horizontally from the building wall 17, The process involves sliding the mounting portion 63 along the longitudinal direction of the lintel 31 while it is still placed on the seat portion 39, so that the side portion 67 of the hanging piece portion 65 that hangs down from the front edge of the mounting portion 63 comes into contact with the notched edge 47 which is adjacent to the seat portion 39 and located at a predetermined length C from the edge of the lintel 31 and perpendicular to the building wall 17, It is characterized by including.

[0025] In this construction method for the opening / closing storage section, a pair of vertical frames 29 are attached to the building wall 17 at the same height, sandwiching the opening 19 in the width direction. The ends 32 of the lintel 31 are connected to the upper ends of the vertical frames 29. This allows the lintel 31 to be installed horizontally. Next, the mounting portion 63 of the support plate 23 is placed on the seat portion 39 provided on the lintel 31. The support plate 23 is positioned vertically by the mounting portion 63 resting on the horizontal seat portion 39 of the lintel 31. With the mounting portion 63 resting on the seat portion 39, the support plate 23, positioned vertically, slides along the longitudinal direction of the lintel 31 while remaining on the seat portion 39. As the support plate 23 slides, the side portion 67 of the hanging piece 65 that curves and hangs down from the front edge of the mounting portion 63 contacts the notched edge 47 at a predetermined distance C from the edge 43 of the lintel 31. In other words, the sliding of the support plate 23 is restricted when the hanging piece 65 contacts the notched edge 47. This positions the support plate 23 in the left-right direction. In this construction method for the opening / closing body storage section, the flat mounting section 63 is placed on the flat seat 39 in plane-to-plane contact, so the vertical positioning of the support plate 23 can be achieved with stable contact. That is, the support plate 23 does not tilt in the front, back, left, or right directions. Furthermore, by sliding the support plate 23 while it is placed on the seat 39, the side portion 67 of the hanging piece 65 that hangs down from the mounting section 63 comes into contact with the notched edge 47, so the horizontal positioning of the support plate 23 can be achieved with stable contact and distance from the striped edge 43. For this reason, compared to conventional positioning work where two marks are aligned by visual inspection, the proportion of work that depends on the worker's skill is reduced, and variations in accuracy can be suppressed. The storage unit 13 is then attached horizontally to the building wall 17 via a support plate 23, along the lintel 31, without tilting.

[0026] The method for constructing an opening / closing body storage section according to claim 10 of the present invention is a method for constructing an opening / closing body storage section in which a support plate 23 is attached to a building wall 17 based on a lintel 31 provided in an opening 19, and a storage section 13 capable of accommodating an opening / closing body is supported on the support plate 23, The process involves placing the mounting portion 63 provided on the support plate 23 onto the seat portion 39 provided on the lintel 31 and extending horizontally from the building wall 17, The process involves sliding the mounting portion 63 along the longitudinal direction of the lintel 31 while it remains mounted on the seat portion 9, so that the side portion 67 of the hanging piece portion 65 that hangs down from the front edge of the mounting portion 63 comes into contact with the notched edge 47 which is adjacent to the seat portion 39 and located at a predetermined length C from the edge 43 of the lintel 31 and perpendicular to the building wall 17, The process of attaching the base plate 61 of the support plate 23 to the building wall 17, The process involves attaching the storage unit 13 to the support arm 51 provided on the support plate 23, It is characterized by including.

[0027] In this construction method for the opening / closing storage section, the mounting portion 63 of the support plate 23 is placed on the seat portion 39 provided on the lintel 31 located in the opening 19. The support plate 23 has a horizontal mounting portion 63 that is bent vertically and extended from the lower end of a base plate 61 parallel to the building wall 17, and this mounting portion 63 rests on the seat portion 39. The support plate 23 is positioned vertically by the mounting portion 63 resting on the horizontal seat portion 39 of the lintel 31. With the support plate 23 positioned vertically by the mounting portion 63 resting on the seat portion 39, it slides along the longitudinal direction of the lintel 31 while remaining on the seat portion 39. As the support plate 23 slides, the side portion 67 of the hanging piece portion 65 that curves and hangs down from the front edge of the mounting portion 63 contacts the notched edge 47 at a predetermined distance C from the edge 43 of the lintel 31. In other words, the sliding of the support plate 23 is restricted when the hanging piece 65 contacts the notched edge 47. This positions the support plate 23 in the left-right direction. In this method of constructing the opening / closing storage unit, the mounting part 63 is placed in contact with the base 39, so the vertical positioning of the support plate 23 can be achieved with stable contact. That is, the support plate 23 does not tilt in the front, back, left, or right directions. Furthermore, by sliding the support plate 23 while it is placed on the base 39, the side portion 67 of the hanging piece 65 hanging from the mounting part 63 comes into contact with the notched edge 47, so the horizontal positioning of the support plate 23 can be achieved with stable contact and at a distance C from the lintel edge 43. Therefore, compared to conventional positioning work where two marks are aligned by visual inspection, the proportion of work that depends on the worker's skill is reduced, and variations in accuracy can be suppressed. The storage unit 13 is then attached to the building wall 17 horizontally along the lintel 31 via the support plate 23 without tilting.

[0028] The method for constructing an opening / closing body storage section according to claim 11 of the present invention is a method for constructing an opening / closing body storage section in which a support plate 23 is attached to a building wall 17 based on a lintel 31 provided in an opening 19, and a storage section 13 capable of accommodating an opening / closing body is supported on the support plate 23, The process involves attaching a pair of left and right vertical frames 29 to the building wall 17 at the same height, sandwiching the opening 19 in the width direction. The process involves connecting the upper ends of the vertical frames 29 with the lintel 31 and fixing the lintel 31 to the building wall 17, The process involves placing the mounting portion 63 provided on the support plate 23 onto the seat portion 39 provided on the lintel 31 and extending horizontally from the building wall 17, The process involves sliding the mounting portion 63 along the longitudinal direction of the lintel 31 while it is still placed on the seat portion 39, so that the side portion 67 of the hanging piece portion 65 that hangs down from the front edge of the mounting portion 63 comes into contact with a notched edge 47 that is adjacent to the seat portion 39 and located at a predetermined length C from the edge 43 of the lintel 31 and perpendicular to the building wall 17, The process of attaching the base plate 61 of the support plate 23 to the building wall 17, The process involves attaching the storage unit 13 to the support arm 51 provided on the support plate 23, It is characterized by including.

[0029] In this construction method for the opening / closing storage section, a pair of vertical frames 29 are attached to the building wall 17 at the same height, sandwiching the opening 19 in the width direction. The ends 32 of the lintel 31 are connected to the upper ends of the vertical frames 29. This allows the lintel 31 to be installed horizontally. Next, the mounting portion 63 of the support plate 23 is placed on the seat portion 39 provided on the lintel 31. The support plate 23 has a horizontal mounting portion 63 that is bent vertically and extended from the lower end of a base plate 61 parallel to the building wall 17, which rests on this seat portion 39. The support plate 23 is positioned vertically by the mounting portion 63 resting on the horizontal seat portion 39 of the lintel 31. With the mounting portion 63 resting on the seat portion 39, the support plate 23, which is positioned vertically, slides toward the center of the lintel 31 while remaining on the seat portion 39. When sliding, the support plate 23 moves parallel to the building wall 17 along the longitudinal direction of the lintel 31. As the support plate 23 slides, the side portion 67 of the hanging piece 65, which curves and hangs down from the front edge of the mounting portion 63, comes into contact with the notched edge 47 at a predetermined distance from the end edge 43 of the lintel 31. In other words, the sliding of the support plate 23 is restricted by the contact of the hanging piece 65 with the notched edge 47. This positions the support plate 23 in the left-right direction. In this construction method for the opening and closing storage section, the flat mounting portion 63 is placed on the flat seat portion 39 in plane-to-plane contact, so the support plate 23 can be positioned in a stable contact state in the vertical direction. That is, the support plate 23 does not tilt in the front, back, left, or right directions. Furthermore, by sliding the support plate 23 while it is resting on the seat portion 39, the side portion 67 of the hanging piece portion 65 that hangs down from the mounting portion 63 comes into contact with the notched edge 47, allowing the support plate 23 to be positioned in a stable contact state in the left-right direction and at a distance from the lintel edge 43. As a result, compared to conventional positioning work that involves aligning two marks by eye, the proportion of work that depends on the worker's skill is reduced, and variations in accuracy can be suppressed. The storage portion 13 is then attached to the building wall 17 horizontally along the lintel 31 via the support plate 23 without tilting.

[0030] The method for constructing an opening / closing body storage section according to claim 12 of the present invention is the method for constructing an opening / closing body storage section according to any one of claims 8 to 11, The cable 73, which is pulled out from the building wall 17, is routed into a cable passage recess located near the seat portion 39 and closer to the center of the lintel than the cut edge 47, and is led out from the end of the lintel, passing under the seat portion.

[0031] In this method of constructing the opening / closing storage unit, the cable 73 pulled out from the building wall 17 is drawn into a recessed cable passage recess 49 formed in the lintel 31. By passing the cable 73 through this cable passage recess 49, it becomes possible to route the cable 73 along the underside of the base 39 along the lintel 31 and pull it out to the outside from the end 32 of the lintel 31. With the cable 73 pulled out, the storage unit 13 rests on the base 39 of the lintel 31. The storage unit 13, which rests on the base 39, is supported by brackets 21 on both sides which are supported by support plates 23. The storage unit 13, supported by support plates 23, then rests on the mounting portion 63 of the support plates 23 which rest on the base 39. When the storage unit 13 is supported by support plates 23, it covers the cable exit hole 71 of the building wall 17 with its back. Before the storage unit 13 is supported by the support plate 23, the cable 73 pulled out from the end 32 of the lintel 31 does not interfere with the storage unit 13 when it is installed. After the storage unit 13 is supported, the cable 73 is pulled inside the storage unit 13 and connected, or passed through the vertical frame 29, so that it is no longer exposed to the outside. [Effects of the Invention]

[0032] According to the mounting structure for the opening / closing body storage section described in claim 1 of the present invention, the lintel is provided with a seat portion and a notched edge, and the support plate is provided with a mounting portion and a hanging portion. This allows for vertical and horizontal positioning of the support plate with simple actions such as placing it on top of the lintel, enabling the support plate for mounting the storage section to be fixed with minimal error using simple operations, and allowing the storage section to be mounted along the lintel.

[0033] According to the mounting structure for the opening / closing body storage section described in claim 2 of the present invention, the lintel is provided by connecting the upper ends of a pair of left and right vertical frames, thereby allowing the lintel to be fixed horizontally to the building wall above the opening, and the storage section can be mounted horizontally along the lintel by support plates placed at both ends of the lintel.

[0034] According to the mounting structure for the opening / closing body storage section described in claim 3 of the present invention, the mounting portion of the support plate that rests on the lintel seat can be formed by bending the base plate once. Compared to the conventional structure in which the lower end of the hanging piece, which is formed in a crank shape in side view by bending it twice, contacts the lintel, the influence of variations in the bending angle can be halved. This makes it possible to suppress errors in the overall height of the support plate from the lintel. In other words, the horizontal accuracy of the storage section, which is supported on both sides by the support arms of the support plate, can be improved.

[0035] According to the mounting structure for the opening / closing body storage section described in claim 4 of the present invention, the storage section is positioned on the base and placed on the support plate, and the bracket of the storage section engages with the engaging portion of the support arm. As a result, the mounting state with the support plate is not only placed but also engaged, allowing for temporary fixing to the building wall, and enabling the storage section to be fixed to the building wall without shifting via the support plate.

[0036] According to the mounting structure for the opening / closing body storage section described in claim 5 of the present invention, the cable pulled out from the building wall can be routed through the cable passage recess in the lintel and under the base, and pulled out from the end of the lintel, allowing for a neat connection to the storage section or the like without interference with other components or exposing the cable.

[0038] According to the mounting structure for the opening / closing body housing described in claim 7 of the present invention, the same effect as in claim 5 can be obtained.

[0039] According to the installation method for the opening / closing body storage section described in claim 8 of the present invention, the vertical and horizontal positioning of the support plate is completed by a simple operation of placing the mounting portion of the support plate on the base portion of the lintel and bringing the hanging portion of the support plate into contact with the notch of the lintel, and the support plate for attaching the storage section can be fixed with minimal error through a simple operation.

[0040] According to the construction method for the opening / closing body storage section described in claim 9 of the present invention, the vertical and horizontal positioning of the support plate is completed by a simple operation of placing the mounting portion of the support plate on the base portion of the lintel and bringing the hanging portion of the support plate into contact with the notch of the lintel. The support plate for attaching the storage section can be fixed with minimal error using a simple operation, and the storage section can be attached to the building wall along the lintel which is horizontally fixed to the upper ends of the left and right vertical frames.

[0041] According to the construction method for the opening / closing body storage section described in claim 10 of the present invention, the vertical and horizontal positioning of the support plate is completed by a simple operation of placing the mounting portion of the support plate on the base portion of the lintel and bringing the hanging portion of the support plate into contact with the notch portion of the lintel. The support plate for attaching the storage section can be fixed with minimal error using a simple operation, and the storage section can be attached to the building wall via a support arm provided on the base plate.

[0042] According to the construction method for the opening / closing body storage section described in claim 11 of the present invention, the vertical and horizontal positioning of the support plate is completed by a simple operation of placing the mounting portion of the support plate on the base portion of the lintel and bringing the hanging portion of the support plate into contact with the notch of the lintel.

[0045] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figure 1 is an exploded perspective view of an opening / closing device equipped with a mounting structure for the opening / closing body housing according to this embodiment. The mounting structure of the opening / closing element storage unit according to this embodiment can be suitably used for a window shutter 11, which is an opening / closing element device. The window shutter 11 is broadly divided into a storage unit 13, which is the opening / closing element storage unit, and a frame 15. The storage unit 13 retractably houses a shutter curtain (not shown), which is an opening / closing element that opens and closes an opening 19 in a building wall 17. The storage unit 13 is formed in a substantially rectangular parallelepiped shape that is long in the width direction of the opening 19. The storage unit 13 is attached to the building wall 17 by brackets 21 on both sides in the longitudinal direction being supported by a pair of support plates 23 that are fixed to the building wall 17.

[0046] The frame 15 is attached to the building wall 17 so as to surround the sash frame 25 which is attached to the opening 19 in the building wall 17. The frame 15 has a horizontal lower frame 27 which is attached to the building wall 17 below the sash frame 25, a pair of left and right vertical frames 29 which are fixed at the lower ends of both the left and right ends of the lower frame 27 and attached vertically to the building wall 17, sandwiching the opening 19 in the width direction, and a lintel 31 which is an upper frame that connects the upper ends of the pair of left and right vertical frames 29 by fixing them at the ends 32 on both sides in the longitudinal direction. The pair of left and right vertical frames 29 include guide rails which are inserted on both sides of the shutter curtain and guide its raising and lowering. The mounting structure of the opening and closing body storage section has a support plate 23 which is attached to the building wall 17 with respect to the lintel 31 and supports the brackets 21 on both sides in the longitudinal direction of the storage section 13.

[0047] Figure 2 is a perspective view of the lintel 31 shown in Figure 1. The lintel 31 is obtained from sheet metal or the like as a long material that extends in the width direction of the opening 19 by press working or the like. The lintel 31 has a horizontal plate portion 33 that extends in the longitudinal direction and is perpendicular to the building wall 17. The horizontal plate portion 33 is located along the upper edge of the opening 19. A rib 35 is formed on the front edge of the horizontal plate portion 33 opposite to the building wall 17, rising vertically from the horizontal plate portion 33. In addition, a vertical plate portion 37 is formed on the rear edge of the horizontal plate portion 33, rising higher than the rib 35 from the horizontal plate portion 33.

[0048] The vertical plate portion 37 has a base plate portion 38 formed at its upper end, which is parallel to the horizontal plate portion 33 and curves at a right angle toward the front. Seat portions 39 are formed at both ends of the base plate portion 38, which is the end portion 32 located above the vertical frame 29. The upper surface of the seat portion 39 is the part on which the support plate 23 is placed. A hanging rib 41 is formed on the front edge of the base plate portion 38, hanging at a right angle. The lintel 31 has multiple notches made in these horizontal plate portion 33 and base plate portion 38. The notching may be done simultaneously when punching out the raw material that will become the lintel 31.

[0049] Notches 45 are formed at both ends 32 in the longitudinal direction of the base portion 38 of the lintel 31. The notches 45 are formed on the front edge side of the seat portion 39 and are formed by cutting out an L-shape with a parallel cut edge 46 parallel to the building wall 17 and a vertical cut edge 47 perpendicular to the building wall 17. The vertical cut edge 47 of this notch 45 is located adjacent to the seat portion 39 and is set at a predetermined length C from the edge 43 of the lintel 31, and has the function of positioning the support plate 23 as will be described later. In addition, a cable passage recess 49 is formed in the base portion 38, located near the seat portion 39 and cut out in a concave shape from the front end opposite to the building wall 17. The cable passage recess 49 is located at each end 32 of the base portion 38, closer to the center in the longitudinal direction of the lintel 31 than the vertical cut edge 47.

[0050] Figure 3(a) is a perspective view of the support plate 23, and (b) is a front view of the support plate 23. The support plate 23 is obtained from sheet metal or the like by press forming or the like into a roughly rectangular shape that is vertically elongated when viewed from the front. The support plate 23 has support arms on the top and bottom that support the bracket 21 of the storage section 13. The support arms are plate-shaped and parallel to the vertical plane and perpendicular to the building wall 17. The support arms are composed of an upper support arm 51 and a lower support arm 53 that are spaced apart vertically. A convexly protruding engaging portion 55 is formed on the upper edge of the upper support arm 51. The engaging portion 55 engages with an upper engaged portion 57 (see Figure 6) provided on the bracket 21 of the storage section 13 (see Figure 6). The upper edge of the lower support arm 53 engages with a lower engaged portion 59 (see Figure 6) provided on the bracket 21 of the storage section 13.

[0051] The support plate 23 has a base plate 61 that curves parallel to the building wall 17 from the support arms 51 and 53 and is attached to the building wall 17. The base plate 61 is formed as a roughly rectangular shape that is long vertically. The upper support arm 51 and the lower support arm 53 are provided on one of the outer long sides of the base plate 61, spaced apart vertically. The support plate 23 has a horizontal mounting portion 63 that curves perpendicularly to the building wall 17 from the lower end of the base plate 61 and rests on the seat portion 39 of the lintel 31. The lower surface of the mounting portion 63 is a horizontally elongated rectangular flat surface. The support plate 23 also has a hanging portion 65 that curves parallel to the building wall 17 and hangs down from the front edge of the mounting portion 63 opposite to the building wall 17. When the support plate 23's mounting portion 63 rests on the seat portion 39 of the lintel 31, the hanging portion 65 hangs down from the front edge of the seat portion 39 through the notch portion 45, and the side portion 67 of the hanging portion 65 can come into contact with the vertical cut edge 47.

[0052] The distance A from the lower surface of the mounting portion 63, which is placed on the seat portion 39, to the upper edge of the upper support arm 51 of the support plate 23 determines the mounting height of the storage portion 13 from the lintel 31. Also, the distance B from the other long side of the support plate 23, which is the same side as the side portion 67 and does not have a support arm 51, to the engaging portion 55 determines the left-right position of the storage portion 13 relative to the lintel 31. The position of the support plate 23 relative to the lintel 31 is determined by these distances A and B.

[0053] Next, the procedure for constructing the opening / closing mechanism housing according to this embodiment will be described. Figure 4 is an exploded perspective view of the main parts before the support plate 23 is fixed to the lintel 31, whose end portion 32 is fixed to the vertical frame 29. To support the storage unit 13 to the building wall 17, a pair of vertical frames 29 are attached to the building wall 17 at the same height, sandwiching the opening 19 in the width direction. Next, the upper ends of the vertical frames 29 are connected with a lintel 31, and the vertical plate portion 37 of the lintel 31 is fixed to the building wall 17. The ends 32 at both ends in the longitudinal direction of the lintel 31 are fixed to the upper ends of the pair of vertical frames 29, so that it is supported horizontally above the opening 19.

[0054] Next, the mounting portion 63 of the support plate 23 is placed on the seat portion 39 provided on the lintel 31. The support plate 23 is slid along the lintel 31 with the mounting portion 63 still on the seat portion 39. As the support plate 23 is slid, the side portion 67 of the hanging piece 65, which hangs down parallel to the building wall 17 from the front edge of the mounting portion 63 opposite to the building wall 17, comes into contact with the vertical cut edge 47 of the notch portion 45 adjacent to the seat portion 39.

[0055] Figure 5 is a perspective view of the mounting structure of the opening / closing body storage section, in which the support plate 23 is positioned on the lintel 31. The support plate 23 is positioned in a predetermined location by placing the mounting portion 63 on the seat portion 39 and bringing the side portion 67 of the hanging piece portion 65 into contact with the vertical cut edge 47 of the notch portion 45. This determines the relative position of the support plate 23 with respect to the lintel 31. Specifically, the mounting height of the support plate 23 from the lower surface of the mounting portion 63 to the upper edge of the upper support arm 51 is distance A, and the left-right position of the storage portion 13 at the end portion 32 of the lintel 31 is distance B. This distance B is based on the position of the vertical cut edge 47, which is a predetermined length C from the end edge 43 of the lintel 31. With the mounting portion 63 "placed" and the hanging piece portion 65 "contacting" the support plate 23, the base plate 61 is fixed to the building wall 17 with fasteners such as screws 69. In this way, the support plate 23 is positioned and fixed to the building wall 17 with respect to the lintel 31.

[0056] A cable 73 is routed from a cable exit hole 71 drilled in the building wall 17 at a predetermined location on the side of the support plate 23 and above the lintel 31, specifically between the left and right support plates 23 and above the lintel 31. Preferably, before fixing the support plate 23, the cable 73 is pulled into a cable passage recess 49 cut out in a concave shape from the front end of the seat portion 39 near the notch 45, and then led out from the end 32 of the lintel 31, passing under the seat portion 39. Note that even after fixing the support plate 23, the cable 73 can still be led out from the end 32 of the lintel 31, passing under the seat portion 39.

[0057] Figure 6 is an exploded perspective view of the main parts showing the storage section 13 being supported by the support plate 23. Once the cable 73 is pulled out from the end 32 of the lintel 31, the storage unit 13 is supported on the building wall 17. The storage unit 13 is a heavy object that has a shutter curtain wound around a winding drum and houses an opening and closing mechanism including a drive motor, reduction gear group, and sprocket. The storage unit 13 is supported horizontally by a crane or by multiple people and inserted between a pair of left and right support plates 23 at a height where the upper engaged portion 57 is above the engaging portion 55 of the upper support arm 51.

[0058] The storage unit 13, inserted between the left and right support plates 23, has an engaging portion 55 on the upper support arm 51 that engages with an upper engaged portion 57 on the bracket 21 of the storage unit 13. The support arms are such that the lower support arm 53 supports the lower engaged portion 59 of the storage unit 13 at its upper edge, and the engaging portion 55 of the upper support arm 51 engages with the upper engaged portion 57 on the bracket 21 of the storage unit 13. With the left and right brackets 21 supported by the support plates 23, the lower surface 75 of the stepped portion on the rear side that runs along the building wall 17 rests on the mounting portion 63. In addition, the engaging portion 55 with the engaged portion 57 of the bracket 21 allows the storage unit 13 to be temporarily fixed to the building wall 17. Subsequently, the support arms 51, 53 and the bracket 21 are fastened with screws or the like (not shown). This completes the attachment of the storage unit 13 to the building wall 17.

[0059] Next, I will explain the function of the above-described configuration.

[0060] In the mounting structure of the opening / closing body storage section according to this embodiment, the lintel 31 is provided by connecting the upper ends of a pair of left and right vertical frames 29 that are attached to the building wall 17, sandwiching the opening 19 in the width direction. As a result, the lintel 31 is fixed horizontally to the building wall 17 above the opening 19.

[0061] The lower ends of the pair of vertical frames 29 are connected to the longitudinal ends of the lower frame 27, which is horizontally fixed to the building wall 17 below the opening 19. As a result, the pair of vertical frames 29, which are formed to the same length, are mounted vertically with their respective lower ends in contact with the lower frame 27, thereby allowing the lintel 31 to be positioned horizontally.

[0062] The lintel 31 has seat portions 39 formed at both ends 32 in the longitudinal direction, on which the support plate 23 can be placed. The support plate 23 has a mounting portion 63 that is bent vertically and extended from a base plate 61 parallel to the building wall 17, which rests on this seat portion 39. The support plate 23 is positioned vertically by the mounting portion 63 resting on the seat portion 39 of the horizontal lintel 31.

[0063] The support plate 23, whose vertical positioning is achieved by the placement of the mounting portion 63 on the seat portion 39, slides towards the center of the lintel 31 while remaining on the seat portion 39. As a result, the side portion 67 of the hanging portion 65, which curves and hangs down from the front edge of the mounting portion 63, comes into contact with the vertical notch edge 47 adjacent to the seat portion 39. In other words, the sliding of the support plate 23 is restricted by the contact of the hanging portion 65 with the vertical notch edge 47. This positions the support plate 23 in the left-right direction.

[0064] In this mounting structure for the opening / closing body storage section, the flat mounting section 63 is placed on the flat base section 39 in plane-to-plane contact, allowing the support plate 23 to be positioned in a stable contact state in the vertical direction. In other words, the support plate 23 does not tilt in the front, back, left, or right directions.

[0065] Furthermore, by sliding the support plate 23 while it is resting on the seat portion 39, the side portion 67 of the hanging piece portion 65 that hangs down from the mounting portion 63 comes into contact with the vertical cut edge 47, allowing the support plate 23 to be positioned in a stable contact state in the left-right direction. As a result, compared to conventional positioning work that involves aligning two marks by visual inspection, the proportion of work that depends on the operator's skill is reduced, and variations in accuracy can be suppressed.

[0066] Furthermore, since the mounting portion 63 of the support plate 23, which rests on the seat portion 39 of the lintel 31, can be formed by bending the base plate 61 once, the influence of variations in bending angle can be halved compared to the conventional structure in which the lower end of the hanging piece, formed in a crank shape in side view by bending twice, abuts against the lintel 31. This also suppresses errors in the overall height of the support plate 23 from the lintel 31. In other words, the horizontal accuracy of the storage section 13, which is supported on both sides by the support plate 23, can be improved.

[0067] Furthermore, in this mounting structure for the opening / closing storage unit, a cable passage recess 49 is provided near the base portion 39 of the lintel 31. The cable passage recess 49 is formed by cutting out a concave shape from the front end of the base portion 39 on the side opposite the building wall 17 toward the building wall 17. The cable 73 pulled out from the building wall 17 can be routed along the underside of the base portion 39 along the lintel 31 by passing it through this cable passage recess 49, and then pulled out to the outside from the end portion 32 of the lintel 31. In other words, a part of the lintel 31 is used as a wiring duct. After the cable 73 is pulled out, the storage unit 13 rests on top of the base portion 39 of the lintel 31. Since the cable 73 is routed along the underside of the base portion 39, it does not interfere with the storage unit 13. The storage unit 13, which rests on the base portion 39, is supported by support plates 23 at both sides by brackets 21.

[0068] The storage unit 13, installed in this manner, covers the cable exit hole 71 in the building wall 17 from the back. The cable 73 pulled out from the end 32 of the lintel 31 is either pulled into the storage unit 13 and connected, or passed through the vertical frame 29, so that it is not exposed to the outside.

[0069] Furthermore, a notch 45 is provided on the front edge side of the seat portion 39 on the end portion 32 side of the cable passage recess 49, through which the hanging piece 65 of the support plate 23 hangs down. Since the hanging piece 65 hangs down from the front edge of the mounting portion 63 that protrudes from the base plate 61 of the support plate 23 toward the opposite side of the building wall 17, a space is formed between it and the vertical plate portion 37 which becomes the back wall of the lintel 31. The cable 73 that has been pulled into the cable passage recess 49 is pulled out from the end portion 32 of the lintel 31, traversing the space provided between the lower surface of the seat portion 39 and the vertical plate portion 37 of the lintel 31 and this hanging piece 65. As a result, the cable 73 pulled out from the building wall 17 can be passed through the cable passage recess 49 of the lintel 31 and pulled out from the end 32 of the lintel 31 to the outside of the lintel 31, and the cable 73 can be connected to the storage section 13 etc. in an aesthetically pleasing manner without being exposed and without interference such as being pinched by other members.

[0070] In the construction method for the opening / closing mechanism storage section according to this embodiment, a pair of left and right vertical frames 29 are attached to the building wall 17 at the same height, sandwiching the opening 19 in the width direction. The ends 32 of the lintel 31 are connected to the upper ends of the vertical frames 29. As a result, the lintel 31 is installed horizontally.

[0071] The lower ends of the pair of vertical frames 29 are connected to the longitudinal ends of the lower frame 27, which is horizontally fixed to the building wall 17 below the opening 19. As a result, the pair of vertical frames 29, which are formed to the same length, are mounted vertically with their respective lower ends in contact with the lower frame 27, thereby allowing the lintel 31 to be positioned horizontally.

[0072] Next, the mounting portion 63 of the support plate 23 is placed on the seat portion 39 provided on the lintel 31. The mounting portion 63 of the support plate 23 is bent perpendicularly from the base plate 61 which is parallel to the building wall 17, and rests on this seat portion 39. The vertical position of the support plate 23 is determined by the mounting portion 63 resting on the seat portion 39 of the horizontal lintel 31.

[0073] The support plate 23, whose vertical position is determined by the placement of the mounting portion 63 on the seat portion 39, slides towards the center of the lintel 31 while remaining on the seat portion 39. During sliding, the support plate 23 moves parallel to the building wall 17 along the longitudinal direction of the lintel 31.

[0074] As the support plate 23 slides, the side portion 67 of the hanging piece 65, which curves and hangs down from the front edge of the mounting portion 63, contacts the notched edge 47 at a predetermined distance from the end edge 43 of the lintel 31. In other words, the sliding of the support plate 23 is restricted by the contact of the hanging piece 65 with the vertical notched edge 47. This positions the support plate 23 in the left-right direction.

[0075] In this construction method for the opening / closing mechanism storage section, the flat mounting section 63 is placed on the flat base section 39 in plane-to-plane contact, allowing the support plate 23 to be positioned in a stable contact state in the vertical direction. In other words, the support plate 23 does not tilt in the front, back, left, or right directions.

[0076] Furthermore, by sliding the support plate 23 while it is resting on the seat portion 39, the side portion 67 of the hanging piece portion 65 that hangs down from the mounting portion 63 comes into contact with the vertical cut edge 47 of the notch portion 45, thereby ensuring stable contact of the support plate 23 in the left-right direction and allowing it to be positioned by its distance from the lintel edge 43. As a result, compared to conventional positioning work that involves aligning two marks by eye, the proportion of work that depends on the worker's skill is reduced, and variations in accuracy can be suppressed. The storage portion 13 is then attached to the building wall 17 horizontally along the lintel 31 via the support plate 23 without tilting.

[0077] In this construction method for the opening / closing mechanism storage section, the cable 73 pulled out from the building wall 17 is drawn into a cable passage recess 49 that is cut out in a concave shape from the front end of the seat portion 39 near the notch 45 in the lintel 31. By passing the cable 73 through this cable passage recess 49, it becomes possible to route the cable 73 along the underside of the seat portion 39 along the lintel 31 and pull it out to the outside from the end 32 of the lintel 31.

[0078] After the cable 73 is pulled out, the storage section 13 of the lintel 31 rests on the base 39. The storage section 13, resting on the base 39, is supported by the support plate 23 at both sides by brackets 21. The storage section 13, supported by the support plate 23, then rests on the mounting section 63 of the support plate 23 that is resting on the base 39. Once supported by the support plate 23, the storage section 13 covers the cable exit hole 71 in the building wall 17 from the back.

[0079] Before the storage unit 13 is supported by the support plate 23, the cable 73 pulled out from the end 32 of the lintel 31 does not interfere with the storage unit 13 when it is installed. After the storage unit 13 is supported, the cable 73 is no longer exposed to the outside, either by having its end with a connector 77 pulled inside and connected to the storage unit 13, or by being passed through the vertical frame 29.

[0080] Furthermore, the cable 73 can be pulled out from the end 32 of the lintel 31 before the storage section 13 is supported, either before or after the support plate 23 is fixed. The hanging piece 65 hangs down from the front edge of the mounting section 63 that protrudes from the base plate 61 of the support plate 23 toward the opposite side of the building wall 17, so there is sufficient space between it and the vertical plate section 37 of the lintel 31. The cable 73, pulled into the cable passage recess 49, can be pulled out from the end 32 of the lintel 31 by crossing the space between the vertical plate section 37 and the hanging piece 65 of the lintel 31 and the space provided beneath the seat section 39. As a result, the cable 73 pulled out from the building wall 17 can be passed through the cable passage recess 49 of the lintel 31 and pulled out from the end 32 of the lintel 31 before the storage section 13 is installed, so it can be connected to the storage section 13 in an aesthetically pleasing manner without interfering with anything else or exposing the cable 73.

[0081] Therefore, according to the mounting structure of the opening / closing body storage section of this embodiment, the lintel 31 is provided with a seat portion 39 and a notch portion 45, and the support plate 23 is provided with a mounting portion 63 and a hanging portion 65. As a result, positioning is possible with simple actions such as placing or applying the support plate 23, and the support plate 23 for attaching the storage section 13 can be fixed with minimal error using simple work.
