DETAILED DESCRIPTION OF THE INVENTION

[0009] [First embodiment] A first embodiment of the present invention will be described below with reference to the drawings. In Figures 1 and 2, the shutter 1 is installed on the building's structure so that it can open and close an opening in the structure, and comprises a frame body 2 and a shutter main body 4 (shutter device) that is assembled to the frame body 2 as shown in Figure 3. In the following description, the left-right direction of the shutter 1 is the X-axis direction, the up-down direction of the shutter 1 is the Y-axis direction, and the front-to-back direction of the shutter 1 (view direction, indoor / outdoor direction) is the Z-axis direction. The X, Y, and Z-axis directions are perpendicular to each other.

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

[0011] [Shutter body] The shutter main body 4 is formed long in the X-axis direction and includes a shutter curtain 41 made up of a plurality of connected slats 3, a shutter winding shaft 42 along the X-axis direction that can wind and unwind the shutter curtain 41, and a shutter case 45 that houses the shutter winding shaft 42. The shutter winding shaft 42 incorporates a tubular motor (not shown) that drives the shaft main body to rotate, a control unit that controls the operation of the tubular motor, and other components. The control unit is connected to a communication device that receives remote signals from a remote control or other remote controller, and controls the operation of the tubular motor based on the signals received by the communication device, thereby controlling the rotation of the shutter winding shaft 42. The shutter curtain 41 is configured by connecting the above-mentioned multiple slats 3 to one another so that they can rotate freely, and the uppermost slat 3 among the multiple slats 3 is attached to the shutter winding shaft 42, and the lowermost slat 3 is attached to a seat plate that sits on the lower frame 26. Therefore, the shutter curtain 41 moves up and down in the Y-axis direction while being guided by the guide rail 211 by the rotation of the shutter winding shaft 42. The shutter case 45 comprises a case back plate 46 aligned along the X-axis direction, and a pair of left and right side plates 47 (casing) whose rear portions are attached to the left and right edges of the case back plate 46 and protrude forward, and a resin side cap 7 that covers the side surface (outer surface) of the shutter main body 4 is removably attached to the side plate 47 at a position forward of the upper part of the vertical frame 21 in the Z-axis direction.

[0012] Fig. 4 shows a side plate 47 to which a shutter assembly auxiliary tool 10 (hereinafter referred to as the auxiliary tool), which will be described later, is attached. Fig. 4(A) is a perspective view showing the side plate 47 and the auxiliary tool 10 from the inside in the X-axis direction (the shutter winding shaft 42 side), and Fig. 4(B) is a perspective view showing the side plate 47 and the auxiliary tool 10 from the outside in the X-axis direction (the side cap 7 side). The side plate 47 includes a side plate main body 471 that rotatably supports one end of the shutter winding shaft 42, a pair of upper and lower mounting pieces 472 that are detachably screwed from the front to the case mounting pieces 52 on the back plate 5 of the vertical frame 21 using screws 8 as fasteners, mounting pieces 473 to which the left and right ends of the lower edge of the inspection panel 23 are detachably screwed, and a pair of upper and lower cap mounting pieces 474 to which the side caps 7 are screwed. A hole 472A into which the screw 8 is threaded is formed in the mounting piece 472, and the cap mounting piece 474 is positioned forward of the mounting piece 472, while the mounting piece 473 is positioned forward of the lower mounting piece 472. The pair of upper and lower mounting pieces 472 are each oriented along the Y-axis direction so as to be positioned on an imaginary vertical line, and are configured to mount the shutter main body 4 to the frame body 2 at ends 4A, 4A of the shutter main body 4. The pair of upper and lower mounting pieces 472 are provided at positions forward in the Z-axis direction from the center of gravity G of the shutter main body 4 (see FIG. 7, etc.). The side plate main body 471 is flat, and a bearing member is attached at its approximate center to rotatably support the shutter winding shaft 42. Here, a roughly arc-shaped slat guide is provided on the inner surface of the side plate main body 471 to accommodate communication devices, wiring, and the like. The mounting pieces 472, 473 and the cap mounting piece 474 extend inward in the X-axis direction toward the fitting portion 20. The upper and lower mounting pieces 472 extend inward in the X-axis direction from the upper and lower edges of the side plate main body 471 and are configured along the Y-axis direction so as to be oriented to be screwed from the front side in the Z-axis direction. The mounting piece 473 extends inward in the X-axis direction from the lower edge of the side plate main body 471 and is configured along the Z-axis direction so as to be screwed from the bottom side in the Y-axis direction. The lower cap mounting piece 474 extends from the lower front edge of the side plate main body 471 and is configured along the Y-axis direction so as to be screwed from the front side in the Z-axis direction, and the upper cap mounting piece 474 extends from the upper front edge of the side plate main body 471 so as to be screwed from the front side in the Z-axis direction. The upper front edge of the side panel body 471 is inclined in the Y-axis direction so that it is positioned rearward (toward the room) from the position of the lower front edge, and therefore the upper cap mounting piece 474 is also positioned at a similar incline.

[0013] The side plates 47 described above constitute the end portions 4A, 4A of the shutter main body 4, and are disposed so as to protrude forward from the vertical frame 21 in the Z-axis direction when the shutter main body 4 is housed in the housing portion 20 and assembled to the frame body 2. The portions of the side plates 47 that protrude from the vertical frame 21 are referred to as front portions 48 of the side plates 47. The mounting pieces 472, 473 and cap mounting piece 474 described above are disposed on the periphery of the front portions 48. Furthermore, the front portions 48 are covered from the outside in the X-axis direction by the side caps 7 that are screwed to the cap mounting pieces 474.

[0014] [Shutter assembly aids] As shown in Figures 4 to 7, the auxiliary device 10 of the first embodiment is made of a metal such as steel or stainless steel and is capable of gripping the shutter body 4 when assembling the shutter body 4 to the frame body 2, and has an attachment portion 11 that is removably attached to the ends 4A, 4A in the X-axis direction of the shutter body 4 (the longitudinal direction of the shutter body 4), and a gripping portion 15 that is continuous with the attachment portion 11 and can be gripped. Furthermore, the auxiliary tool 10 of the first embodiment is formed symmetrically up and down, and by using the upper and lower parts in the forward or reverse direction, it can be used at either one end 4A or the other end 4A of the shutter main body 4. Furthermore, the auxiliary tool 10 can be used both when it is attached internally to the side plate 47 as shown in Fig. 6 and when it is attached externally to the side plate 47 as shown in Fig. 9. In other words, by forming the auxiliary tool 10 symmetrically up and down, it is possible to improve its versatility.

[0015] The mounting portion 11 has an upper mounting portion 12 and a lower mounting portion 13 located below the upper mounting portion 12 in the Y-axis direction. The upper mounting portion 12 is formed in a rectangular plate shape and extends along the Y-axis direction from an upper end portion 151 (described later) of the gripping portion 15. It is also bent downward from the upper end portion 151 to extend along the X-axis direction. The lower mounting portion 13 is formed in a rectangular plate shape and extends along the Y-axis direction from a lower end portion 152 (described later) of the gripping portion 15. It is also bent upward from the lower end portion 152 to extend along the X-axis direction. The upper mounting portion 12 and the lower mounting portion 13 extend along the Y-axis direction so as to be attachable to the pair of upper and lower mounting pieces 472 described above. They are located on an imaginary vertical line along the Y-axis direction in an intermediate state when assembled to the frame 2 of the shutter body 4 and in an attached state. The upper and lower mounting portions 12 and 13 are screwed to the pair of upper and lower mounting pieces 472, respectively.

[0016] In the first embodiment, the gripping portion 15 is formed with a generally U-shaped cross section and has a main body piece 16 extending along the Y-axis direction, an upper piece 17 extending from the upper end of the main body piece 16 along the Z-axis direction, and a lower piece 18 extending from the lower end of the main body piece 16 along the Z-axis direction. The end of the upper piece 17 forms an upper end 151 of the gripping portion 15, and is continuous with the upper mounting portion 12 described above. The end of the lower piece 18 forms a lower end 152 of the gripping portion 15, and is continuous with the lower mounting portion 13 described above. The length dimension of the main body piece 16 in the Y-axis direction is such that its upper end is located slightly above the upper edge of the upper mounting piece 472 of the side plate 47, and its lower end is located slightly below the lower edge of the lower mounting piece 472 of the side plate 47. The dimensions of the upper piece 17 and the lower piece 18 in the Z-axis direction are larger than the dimension in the Z-axis direction from the position of the mounting piece 473 of the side plate 47 to the position of the front edge of the side plate 47. Therefore, in the mounted state where the auxiliary device 10 is mounted on the side plate 47 of the shutter main body 4 (see Figure 4, etc.), the main body piece 16 is positioned further forward in the Z-axis direction than the shutter main body 4. Furthermore, the dimensions of the upper piece 17 and the lower piece 18 in the Z-axis direction are the same.

[0017] In the attached state in which this auxiliary device 10 is attached to the shutter body 4, the attachment position relative to the shutter body 4 is a position forward of the center of gravity G of the shutter body 4. As a result, when the shutter body 4 is assembled to the frame 2 and a part of the shutter body 4 is housed in the housing portion 20, that is, in the intermediate state of assembly of the shutter body 4 to the frame 2 (see FIG. 8), even if the mounting portion 11 of the shutter body 4 is not disposed within the housing portion 20, the center of gravity G of the shutter body 4 can be disposed within the housing portion 20, and the shutter body 4 can be stabilized in the intermediate state.

[0018] [Shutter assembly procedure] The procedure for assembling the shutter 1 using the auxiliary tool 10 of the first embodiment will be described below. First, at the construction site, the frame 2 is prepared, installed at an opening of a building with scaffolding 9 (see FIG. 3) set up around it. Meanwhile, the auxiliary device 10 is attached to both ends 4A, 4A of the shutter body 4 by fastening the upper and lower mounting portions 12, 13 with screws 8 to the mounting pieces 472 of the side panels 47 at both ends 4A, 4A of the shutter body 4. The slats 3 of the shutter body 4 are wound around the shutter winding shaft 42. In the first embodiment, the auxiliary device 10 is oriented vertically so that the gripping portion 15 is positioned inward in the X-axis direction relative to the side panels 47 and the mounting portion 11 extends outward in the X-axis direction. As a result, the auxiliary device 10 is internally attached to the side panels 47 as shown in FIG. 6. The lower piece portion 18 of the auxiliary device 10 is positioned below the end member continuous with the lowest slat 3. Next, the worker 6 grasps the gripping portion 15 of the auxiliary device 10, and inserts at least a part of the shutter main body 4 into the fitting portion 20 of the frame body 2 from the front, so that the center of gravity position G of the shutter main body 4 is positioned within the fitting portion 20, resulting in the intermediate state shown in Figure 8. Here, when the fitting portion 20 of the frame body 2 is located at a low position as shown in FIG. 3 , for example, without using the auxiliary tool 10, it is difficult for the worker 6 to hold the shutter body 4 in a low posture when inserting the shutter body 4 into the fitting portion 20, making it difficult to stably hold the shutter body 4. Furthermore, if the holding positions of both ends 4A, 4A of the shutter body 4 are different, the shutter body 4 may become twisted. In contrast, in the shutter assembly method of the first embodiment, as described above, the auxiliary tool 10 is attached to both ends 4A, 4A of the shutter body 4, so the worker 6 can grasp the gripping portion 15 of the auxiliary tool 10. While holding the shutter body 4 stably in this gripping state, the worker 6 can easily fit a portion of the shutter body 4 into the fitting portion 20. Furthermore, for example, it is difficult to stably hold the shutter body 4 when lifting the shutter body 4 to insert it into the fitting portion 20. However, by using the auxiliary tool 10 of the first embodiment, it is possible to easily fit a portion of the shutter body 4 into the fitting portion 20. Next, the screws 8 are removed from the pair of upper and lower mounting pieces 472 at both ends 4A, 4A of the shutter body 4 in the intermediate state, and then the auxiliary device 10 is slid inward in the X-axis direction relative to the side plate 47 to remove the upper mounting portion 12 and the lower mounting portion 13 from the mounting piece 472. In this manner, the auxiliary device 10 is removed from both ends 4A, 4A of the shutter body 4. Here, for example, if the end 4A is disposed near an inside corner of a building, and the auxiliary device 10 is positioned so that it protrudes outward in the X-axis direction relative to the side plate 47, there is a risk that the auxiliary device 10 will interfere with the inside corner. However, in the first embodiment, because the auxiliary device 10 is configured as described above, it is possible to select between external mounting, located outward in the X-axis direction relative to the side plate 47, and internal mounting, located inward in the X-axis direction, and selecting internal mounting reduces interference with the inside corner. Next, the shutter body 4 is inserted further deeper into the mounting portion 20, and the pair of upper and lower mounting pieces 472 are screwed to the case mounting pieces 52 on the back plate 5 of the frame body 2 with screws 8, thereby finally fixing the shutter body 4 to the frame body 2. Then, the inspection plate 23 and the side cap 7 are attached to the attachment pieces 473 and the cap attachment pieces 474, and the shutter 1 is assembled.

[0019] [Effects of the first embodiment] According to the auxiliary device 10 of the first embodiment, by attaching the mounting portion 11 of each auxiliary device 10 to both end portions 4A, 4A of the shutter body 4, it becomes possible to hold both end portions 4A, 4A of the shutter body 4 by gripping the gripping portion 15, and the shutter body 4 can be held more stably than, for example, when such a gripping portion 15 is not configured on the shutter body at the time of assembly, thereby improving the workability of assembling the shutter body 4 to the frame body 2. Furthermore, since the mounting portion 11 of the auxiliary device 10 is screwed to the mounting piece 472 of the side panel 47 which is screwed to the case mounting piece 52 during the actual fixation, there is no need to provide a part to the shutter body 4 for attaching the mounting portion 11 of the auxiliary device 10 in addition to the mounting piece 472. Furthermore, by selecting the up or down orientation of the auxiliary tool 10, the auxiliary tool 10 can be attached internally or externally to the shutter body 4, so that the auxiliary tool 10 can be arranged in a manner according to the work location, and can also be used for both the left and right end parts 4A, 4A. In addition, since the mounting portion 11 is formed along the Y-axis direction so as to be attached to the mounting piece 472 along the Y-axis direction, deformation is less likely to occur when the auxiliary device 10 holds the shutter body 4 against its own weight, and the mounting strength of the auxiliary device 10 to the shutter body 4 can be improved.

[0020] [Second embodiment] A second embodiment of the present invention will now be described with reference to the drawings. 10, shutter assembling auxiliary tool 10B (auxiliary tool) according to the second embodiment is configured generally similarly to shutter assembling auxiliary tool 10 of the first embodiment, but differs in that it has a receiving piece portion 123, which will be described later. Auxiliary tool 10B also differs from shutter assembling auxiliary tool 10 in that it is equipped with an upper slip-out prevention member 125 having the receiving piece portion 123, and a lower slip-out prevention member 135, which will be described later. 11, the side plate 47 of the shutter main body 4 to which the auxiliary device 10B is attached has a slit 472B instead of the hole 472A of the mounting piece 472, with the slit 472B of the upper mounting piece 472 opening upward and the slit 472B of the lower mounting piece 472 opening downward. The side plate 47 also has an upper piece portion 475 that is continuous with the upper mounting piece 472 and bent forward in the Z-axis direction of the shutter main body 4, and a lower piece portion 476 that is continuous with the lower mounting piece 472 and bent backward in the Z-axis direction of the shutter main body 4. Note that (A) of Figure 10 is a front view showing the main parts of the attached state in which auxiliary device 10B is attached to side plate 47, (B) of Figure 10 is a side view showing the main parts of auxiliary device 10B attached to side plate 47, (A) of Figure 11 is a front view showing side plate 47, and (B) of Figure 11 is a side view showing side plate 47.

[0021] The auxiliary tool 10B shown in Fig. 12 is attached to, for example, the left side plate 47 of the shutter main body 4 shown in Fig. 2. The auxiliary tool 10B (not shown) attached to the right side plate 47 of the shutter main body 4 is configured symmetrically with respect to the auxiliary tool 10B attached to the left side plate 47. The mounting portion 11 has an upper mounting portion 12 and a lower mounting portion 13 located below the upper mounting portion 12 in the Y-axis direction. The upper mounting portion 12 and the lower mounting portion 13 extend along the Y-axis direction so as to be attachable to the pair of upper and lower mounting pieces 472 described above, and are located on imaginary vertical lines along the Y-axis direction in the intermediate state when assembled to the frame 2 of the shutter main body 4 and in the attached state. The upper and lower mounting portions 12 and 13 are screwed to the pair of upper and lower mounting pieces 472, respectively. The auxiliary tool 10B is made of a metal such as steel or stainless steel and is capable of gripping the shutter body 4 when assembling the shutter body 4 to the frame 2. It includes an attachment portion 11 that is removably attached to the ends 4A, 4A of the shutter body 4 in the X-axis direction, and a gripping portion 15 that is continuous with the attachment portion 11 and can be grasped. In the first embodiment, the gripping portion 15 has a generally U-shaped cross section and includes a main body piece 16 extending along the Y-axis direction, an upper piece 17 extending from the upper end of the main body piece 16 along the Z-axis direction, and a lower piece 18 extending from the lower end of the main body piece 16 along the Z-axis direction. The end of the upper piece 17 forms the upper end 151 of the gripping portion 15, and is continuous with the upper attachment portion 12 described above. The end of the lower piece 18 forms the lower end 152 of the gripping portion 15, and is continuous with the lower attachment portion 13 described above.

[0022] The upper mounting portion 12 includes an upper mounting body 121 formed in the shape of a rectangular plate extending from the upper end 151 of the gripping portion 15 along the Y-axis direction and bent downward from the upper end 151 so as to also extend along the X-axis direction, and an upper mounting piece portion 122 removably attached to the upper mounting body 121, and an upper slip-out prevention member 125 having a receiving piece portion 123 that receives the vertical load applied to the upper piece portion 17 of the side plate 47 when attached to the upper mounting piece 472. The lower mounting portion 13 is formed in the shape of a rectangular plate extending along the Y-axis direction from a lower end portion 152 of the gripping portion 15, which will be described later, and is equipped with a lower mounting body 131 that is bent upward from the lower end portion 152 and also extends along the X-axis direction, a lower mounting piece portion 132 (see Figure 14) that is removably attached to the lower mounting body 131, and a bottom-slip prevention member 135 that has a hooking piece portion 133 that hooks onto the lower piece portion 18 of the side plate 47 in the downward direction.

[0023] 13 , in the upper slip-out prevention member 125, the upper mounting piece 122 extends along the XY plane, and the receiving piece 123 is continuous with the upper mounting piece 122 and extends along the XZ plane, and is formed with a generally L-shaped cross section. The upper mounting piece 122 has a hole 126 through which a screw 8A serving as a fastener is inserted to screw the upper mounting piece 122 to the upper mounting main body 121, and a slit 127 that is spaced apart from the hole 126 in the X-axis direction, opens at one end edge of the upper mounting piece 122 in the X-axis direction, and through which a screw 8 is placed to screw the upper slip-out prevention member 125 to the upper mounting piece 472. The receiving piece 123 is formed in a manner generally similar to the upper mounting piece 122, and has the hole 126 and the slit 127. In addition, the anti-top-slip member 125 is provided with a plate-shaped rib 128 that is positioned between the hole 126 and the slit 127 and is welded and fixed to the upper mounting piece portion 122 and the receiving piece portion 123.This increases the strength of the anti-top-slip member 125, and the rib 128 also divides the upper mounting piece portion 122 and the receiving piece portion 123 into left and right portions, making it possible to prevent the anti-top-slip member 125 from shifting significantly from one position to the other when aligning it with the upper mounting piece 472. In addition, in the above-mentioned anti-top-slip member 125, not only the upper mounting piece portion 122 but also the receiving piece portion 123 have holes 126 and slits 127, so even when the anti-top-slip member 125 is rotated, the above-mentioned upper mounting piece portion 122 forms the receiving piece portion and the above-mentioned receiving piece portion 123 forms the upper mounting piece portion, and the anti-top-slip member 125 can be used in this orientation as well, and an anti-top-slip member 125 with a common configuration can be used at either one end or the other end of the shutter body 4 in the X-axis direction.

[0024] 14 , in the lower slip-out prevention member 135, the lower mounting piece 132 extends along the XY plane, and the hook piece 133 extends along the XZ plane, forming a generally L-shaped cross section. The lower mounting piece 132 is formed longer in the Y-axis direction than the lower mounting piece 472, and when attached to the mounting piece 472, it extends downward from the mounting piece 472. The extending portion of the lower mounting piece 132 may be connected to the lower mounting main body 131 or the gripping portion 15 by a wire (not shown) or the like, which prevents the lower slip-out prevention member 135 from falling when the lower mounting piece 132 is removed from the mounting piece 472. The lower mounting piece 132 also has a hole 136 through which a screw 8 is inserted to fasten the lower mounting piece 132 to the lower mounting piece 472.

[0025] [Procedure for attaching and removing auxiliary equipment] The procedure for attaching and detaching the auxiliary tool 10B of the second embodiment to and from the shutter main body 4 will be described below.

[0026] (attachment) The upper part of the support device 10B is as follows. First, the upper mounting body 121 is shallowly screwed onto the upper mounting piece 472 with the screw 8, thereby temporarily fixing the upper mounting body 121. Next, the upper slip-out prevention member 125 is inserted between the mounting piece 472 and the upper mounting body 121 in the X-axis direction, while the screw 8 is placed in the slit 127 of the upper mounting piece portion 122. At this time, the receiving piece portion 123 is placed along the lower side (lower surface) of the upper piece portion 17. Next, the screw 8A is inserted into the hole 126 of the upper mounting piece portion 122 and screwed into the upper mounting body 121, thereby fixing the upper slip-out prevention member 125 to the upper mounting body 121. Next, the screw 8 is further tightened. As a result, at the upper end 151 of the gripping portion 15, the upper mounting main body 121, the upper mounting piece 122, and the upper mounting piece 472 are overlapped in that order from the rear side in the Z-axis direction and fixed to each other by the screw 8, and the upper part of the auxiliary device 10B is finally fixed to the shutter main body. In addition, the receiving piece 123 is fixed in an arrangement that allows it to receive the vertical load of the shutter main body 4 applied to the upper piece 17 of the side plate 47. In this way, an attachment structure in which the auxiliary tool 10B is attached to the shutter main body 4 is formed.

[0027] The lower part of the support device 10B is as follows. First, the lower mounting body 131 is overlapped with the lower mounting piece 472 from the rear side in the Z-axis direction, and the lower mounting piece portion 132 of the bottom slip-off prevention member 135 is overlapped with the lower mounting piece 472 from the front side in the Z-axis direction. At this time, the hook piece portion 133 is arranged along the upper side (upper surface) of the lower piece portion 18. Next, the lower mounting body 131, the lower mounting piece 472, and the lower mounting piece portion 132 are overlapped and fixed to each other in that order from the rear side in the Z-axis direction by the screws 8. The hook portion 133 is fixed in a position where it hooks onto the lower piece portion 18 of the side plate 47 in the downward direction. In this way, the auxiliary tool 10B is attached to the shutter body 4.

[0028] (removal) At the top of the auxiliary tool 10B, the screws 8 and 8A are removed, the upward slip-out prevention member 125 is pulled out in the X-axis direction from between the upper mounting piece 472 and the upper mounting body 121, and then the upper mounting body 121 is removed. Furthermore, at the bottom of the auxiliary tool 10B, the screw 8 is removed, the lower mounting piece 472 and the lower mounting piece portion 132 are separated, and then the lower mounting body 131 is taken out. In this way, the auxiliary tool 10B is removed from the shutter body 4.

[0029] [Effects of the second embodiment] According to the assisting device 10B of the second embodiment, in addition to being able to achieve the same effects as the assisting device 10 of the first embodiment described above, it is also possible to achieve at least the following effects. That is, with auxiliary tool 10B, receiving piece portion 123 receives the vertical load of shutter body 4 applied to upper piece portion 17 of side panel 47, thereby eliminating the risk of upper mounting portion 12 shifting relative to upper mounting piece 472 due to the weight of shutter body 4 and causing screw 8 to come out of slit 472B, and therefore, the attachment state of auxiliary tool 10B to shutter body 4 can be maintained in a suitable state. Also, for example, when removing auxiliary tool 10B from shutter body 4, removing upper slip-out prevention member 125 from upper attachment body 121 prevents said upper slip-out prevention member 125 from getting caught on the shutter body 4, facilitating the removal of auxiliary tool 10B. Furthermore, by hooking the hook portion 133 of the bottom slip-out prevention member 135 onto the side panel 47 of the shutter body 4, it is possible to prevent the lower mounting portion 13 from shifting relative to the lower mounting piece 472 due to tilting or vibration during transportation or carrying of the shutter body 4, and it is possible to eliminate the risk of the screw 8 coming out of the slit 472B, so that the attachment state of the auxiliary device 10B to the shutter body 4 can be maintained in an optimal state.

[0030] [Variations] In the first embodiment, the auxiliary device 10 is attached internally to both end portions 4A, 4A of the shutter main body 4 in the X-axis direction, but this is not limited to this. The auxiliary device 10 may be rotated upside down and attached externally to both end portions 4A, 4A of the shutter main body 4 in the X-axis direction as shown in Figure 9. In the first embodiment, the worker 6 holds the grip portion 15 of the auxiliary tool 10, but this is not limiting, and the shutter main body 4 may be lifted by attaching a string member such as a sling to the grip portion 15. The same may be done in the second embodiment. In the first and second embodiments, the gripping portion 15 of the auxiliary device 10, 10B is formed to have an approximately U-shaped cross section, but this is not limited to this and the gripping portion 15 may have other shapes such as an arc shape or a polygonal shape as long as it can be gripped. In the first embodiment, the attachment portion 11 of the assisting device 10 is attached to the attachment piece 472 of the side plate 47, but this is not limiting, and the attachment portion 11 may be attached to a portion other than the attachment piece 472. In the first embodiment, the mounting portion 11 of the auxiliary device 10 is screwed to both end portions 4A, 4A of the shutter main body 4 with screws 8, but this is not limited to this, and the mounting portion 11 may be attached in other ways, such as by engaging with both end portions 4A, 4A of the shutter main body 4, as long as it is removable. In the first and second embodiments, the upper mounting portion 12 and the lower mounting portion 13 of the auxiliary device 10, 10B are arranged to be positioned on a virtual vertical line along the Y-axis direction when the auxiliary device 10 is attached to the shutter body 4, but this is not limited to this, and the upper mounting portion 12 and the lower mounting portion 13 may be arranged at positions that are off the virtual vertical line when attached. In the first and second embodiments, the mounting portion 11 of the auxiliary device 10, 10B is formed along the Y-axis direction, but this is not limited to this. For example, if the mounting piece 472 is inclined with respect to the Y-axis direction, or if a mounting location other than the mounting piece 472 is inclined with respect to the Y-axis direction, the mounting portion 11 may be inclined with respect to the Y-axis direction depending on the inclination of the mounting piece 472 or the mounting location. In the second embodiment, the receiving piece portion 123 is provided on an anti-slip member 125 that is separate from the upper mounting body 121, and is configured so that it can be attached and detached even when, for example, the end portion 4A is installed near an inside corner of a building. However, this is not limited to this, and if the above-mentioned case does not need to be taken into consideration, the configuration of the anti-slip member 125 may be omitted and the receiving piece portion 123 may be formed directly on the upper mounting body 121. In the second embodiment, a hook portion 133 is provided on the lower mounting portion 13, but this is not limited to this. For example, if the mounting strength of the auxiliary device 10B to the shutter main body 4 is sufficient, the hook portion 133 may be eliminated by omitting the configuration of the bottom slip-out prevention member 135. In the second embodiment, the ribs 128 are provided on the upper slippage prevention member 125, but this is not limiting, and the configuration of the ribs 128 may be omitted if the upper slippage prevention member 125 has sufficient strength. In the second embodiment, the receiving piece portion 123 also has a hole 126 and a slit 127, but this is not limited to this. For example, if there is no need to consider using the anti-top-out member 125 in the rotated orientation as described above, the hole 126 and slit 127 configuration in the receiving piece portion 123 may be omitted.

[0031] [summary] (1) The shutter assembly auxiliary tool of the present invention is a shutter assembly auxiliary tool that can grip the shutter body when assembling the shutter body, which is formed long in the left-right direction, to a frame body, and is characterized by having an attachment part that can be removably attached to the longitudinal end of the shutter body, and a gripping part that is continuous with the attachment part and can be gripped. According to the shutter assembly auxiliary tool of the present invention, by attaching the mounting portion to the end of the shutter body, it is possible to hold the end of the shutter body by gripping the gripping portion, and the shutter body can be held more stably than when, for example, such a gripping portion is not configured on the shutter body at the time of assembly. For example, the shutter body can be assembled to the frame body at a low position on the assembled scaffolding, or the shutter body can be lifted and assembled to the frame body stably, thereby improving the workability of assembling the shutter body to the frame. Furthermore, by attaching the shutter assembly auxiliary tool to each of the both ends of the shutter body, it is easy to align the holding positions that hold both ends of the shutter body, thereby suppressing the occurrence of twisting of the shutter body, and also improving the workability of assembling the shutter body to the frame. (2) In the shutter assembly auxiliary device of the present invention, the shutter body is configured so that, when assembled to the frame body, the end of the shutter body protrudes forward from the frame body, and the gripping portion may have a portion that is positioned forward from the shutter body when the mounting portion is attached to the end of the shutter body. With this configuration, for example, when inserting the shutter body into the frame body from the front side, it is possible to continue to grip the gripping portion, which has a part that is positioned further forward than the shutter body, thereby improving the workability of assembling the shutter body to the frame body. (3) In the shutter assembly aid of the present invention, an attachment piece for attaching the shutter body to the frame body may be provided at the end of the shutter body, and the attachment portion may be positioned so that it can be attached to the attachment piece. With this configuration, the mounting portion of the shutter assembly auxiliary tool can be attached using the aforementioned mounting piece of the shutter body, eliminating the need to provide a separate part on the shutter body for attaching the mounting portion of the shutter assembly auxiliary tool. In this case, the mounting piece of the shutter body is attached to the frame after the mounting portion of the shutter assembly auxiliary tool has been removed from the mounting piece of the shutter body. (4) In the shutter assembly auxiliary tool of the present invention, the mounting portion may extend along the longitudinal direction of the shutter body. With this configuration, the shutter assembly auxiliary tool can be attached internally so that the gripping portion is positioned inside the end of the shutter body in the longitudinal direction of the shutter body, or externally so that the gripping portion is positioned outside the end of the shutter body in the longitudinal direction of the shutter body, allowing the shutter assembly auxiliary tool to be attached to the end of the shutter body in a manner appropriate for the work location. For example, when a building wall forms an internal corner and a shutter is to be installed near the internal corner, attaching the shutter assembly auxiliary tool internally prevents the shutter assembly auxiliary tool from interfering with the internal corner. Furthermore, because the mounting portion extends as described above, when removing the shutter assembly auxiliary tool, the shutter assembly auxiliary tool can be slid inward in the longitudinal direction of the shutter body. Therefore, even when installing a shutter near the internal corner, the shutter assembly auxiliary tool can be easily removed from the shutter body without interfering with the internal corner. (5) In the shutter assembly aid of the present invention, the gripping portion has an upper end and a lower end, and the mounting portion has an upper mounting portion that is continuous with the upper end and a lower mounting portion that is continuous with the lower end, and each of the upper mounting portion and the lower mounting portion may be arranged to be located on a virtual vertical line that extends in the up-down direction when attached to the shutter body. With this configuration, by changing the orientation of the shutter assembly aid, it can be attached either internally or externally to the shutter body, and the shutter assembly aids attached to both ends of the shutter body can be used on both the left and right sides. (6) In the shutter assembly auxiliary device of the present invention, an attachment piece for attaching the shutter body to the frame body is provided along the vertical direction at the end of the shutter body, and the attachment portion may be along the vertical direction so as to be attachable to the attachment piece. With this configuration, compared to when the mounting pieces or mounting portions are inclined relative to the vertical direction, for example, deformation is less likely to occur when the shutter assembly aid holds the shutter body against its own weight, and the mounting strength of the shutter assembly aid to the shutter body can be improved. (7) The shutter assembly method of the present invention is a shutter assembly method for assembling a shutter body formed long in the left-right direction to a frame body, characterized in that the mounting portions of the shutter assembly auxiliary tool of the present invention described above are attached to each of the two end portions of the shutter body, at least a part of the shutter body is positioned within the frame body while being gripped by the gripping portions of the shutter assembly auxiliary tool, the shutter assembly auxiliary tool is removed from each of the two end portions of the shutter body, and the shutter body is finally fixed to the frame body. According to the shutter assembling method of the present invention, it is possible to configure a shutter assembling method that can achieve the same effects as those of the shutter assembling auxiliary tool described above.

[0032] (8) The shutter assembly auxiliary tool of the present invention is a shutter assembly auxiliary tool that can grip a shutter body when assembling the shutter body to a frame body, the shutter body having a long length in the left-right direction and side panels with a pair of upper and lower mounting pieces at the longitudinal ends, and has a mounting portion that can be removably attached to the mounting pieces and a gripping portion that is continuous with the mounting portion and can be grasped, the gripping portion having an upper end and a lower end, the mounting portion having an upper mounting portion that is continuous with the upper end and a lower mounting portion that is continuous with the lower end, and at least the upper mounting portion is configured with a receiving piece portion that receives a vertical load applied to the side panel when attached to the upper mounting piece of the pair of upper and lower mounting pieces. According to the shutter assembly auxiliary tool of the present invention, by attaching the mounting portion to the end of the shutter body, it is possible to hold the end of the shutter body by gripping the gripping portion, and the shutter body can be held more stably than when, for example, such a gripping portion is not configured on the shutter body at the time of assembly. For example, the shutter body can be assembled to the frame body at a low position on the assembled scaffolding, or the shutter body can be lifted and assembled to the frame body stably, thereby improving the workability of assembling the shutter body to the frame. Furthermore, by attaching the shutter assembly auxiliary tool to each of the both ends of the shutter body, it is easy to align the holding positions that hold both ends of the shutter body, thereby suppressing the occurrence of twisting of the shutter body, and also improving the workability of assembling the shutter body to the frame. In addition, with the shutter assembly aid of the present invention, even if, for example, a slit opening upward is formed in the upper mounting piece and the upper mounting part is attached to the mounting piece by a fastener such as a screw passed through this slit, the vertical load applied to the side panel is received by the above-mentioned receiving piece, so that the upper mounting part will not shift relative to the mounting piece due to the weight of the shutter body, eliminating the risk of the fastener coming out of the slit, and therefore the shutter assembly aid can be maintained in a suitable attached state to the shutter body. (9) In the shutter assembly auxiliary device of the present invention, the upper mounting portion comprises an upper mounting body and an anti-top-out member that is removably attached to the upper mounting body, and the anti-top-out member may have the receiving piece portion. With this configuration, for example, when removing a shutter assembly auxiliary tool from the shutter body, the anti-top-slip member can be removed from the upper mounting body, preventing the anti-top-slip member from getting caught on the shutter body, making it easy to remove the shutter assembly auxiliary tool. (10) In the shutter assembly auxiliary device of the present invention, the lower mounting portion comprises a lower mounting body and a bottom-slip prevention member that is removably attached to the lower mounting body, and the bottom-slip prevention member may have a hook portion that hooks onto the side panel in a downward direction. With this configuration, for example, even if a slit opening downward is formed in the lower mounting piece and the lower mounting part is attached to the mounting piece by a fixing device such as a screw passed through this slit, the hooking piece of the above-mentioned anti-slip member hooks onto the side panel of the shutter body, thereby preventing the lower mounting part from shifting relative to the lower mounting piece due to tilting or vibration during transportation or carrying of the shutter body, and eliminating the risk of the fixing device coming off the slit, so the shutter assembly auxiliary device can be kept properly attached to the shutter body. (11) The mounting structure of the present invention is a mounting structure for mounting the shutter assembly auxiliary tool of the present invention described above to a shutter body, wherein the side plate has an upper piece portion that is continuous with the upper mounting piece and is bent toward the front side of the shutter body, and a lower piece portion that is continuous with the lower mounting piece and is bent toward the rear side of the shutter body, the upper mounting portion comprises an upper mounting body and an upward slip-out prevention member having the upper mounting piece and the receiving piece portion that is removably attached to the upper mounting body, and the lower mounting portion comprises a lower mounting body and a lower mounting member that is removably attached to the lower mounting body. and a bottom slip-out prevention member having a lower mounting piece portion and a hooking piece portion that hooks onto the side plate in a downward direction, wherein at the upper end of the gripping portion, the upper mounting body, the upper mounting piece portion and the upper mounting piece are overlapped in that order and fixed to each other by a fastener, and the receiving piece portion is arranged along the underside of the upper piece portion, and at the lower end of the gripping portion, the lower mounting body, the lower mounting piece and the lower mounting piece portion are overlapped in that order and fixed to each other by a fastener, and the hooking piece portion is arranged along the top side of the lower piece portion. According to the mounting structure of the present invention, the upper end of the gripping portion is supported by the receiving piece portion of the upper piece of the side plate so that the load can be supported, thereby maintaining the mounting state of the shutter assembly auxiliary device in an appropriate state.In addition, since the upper mounting piece portion can be removed from the upper mounting body, the upper slip-out prevention member does not get in the way when removing the shutter assembly auxiliary device from the shutter body, making the removal work easy. On the other hand, at the lower end of the gripping portion, the lower mounting piece can be clamped between the lower mounting body and the lower mounting piece, and the hooking piece can be hooked onto the lower piece of the side plate, thereby maintaining the shutter assembly aid in a suitable installation state.
