[Modes for carrying out the invention] 【0008】 The following describes a shutter jig according to one embodiment, based on the drawings. Hereinafter, the shutter jig will be referred to as the shutter jig. As shown in Figure 1, the shutter jig 3 is attached to the shutter curtain 13 of a manual shutter 100, for example. 【0009】 When viewing the manual shutter 100 from the front, the left-right direction along the horizontal axis is referred to as the width direction. The direction within the width direction toward the center of the building opening is referred to as the inside of the width direction. The direction within the width direction toward the edges of the building opening is referred to as the outside of the width direction. The direction along the horizontal axis connecting the indoor side and the outdoor side is referred to as the indoor-outdoor direction. 【0010】 A manual shutter 100 will be described. The manual shutter 100 is installed on the exterior side of an opening in a building. The manual shutter 100 comprises a frame 11, a shutter case 12, a shutter curtain 13, a pair of guide rails 14, 14, and a baseboard 15. In Figure 1, the guide rails 14 and the baseboard 15 are shown by dashed lines. 【0011】 The frame 11 has a four-sided frame structure. The frame 11 is fixed to the opening of the building. The shutter case 12 is fixed to the top plate 11a of the frame 11. 【0012】 The shutter case 12 is box-shaped and opens downwards. The shutter case 12 includes a pair of mounting plates 121, 121 (see Figure 2), a front cover 122, and a pair of end covers 123. In Figure 2, the front cover 122 and end covers 123 are not shown. 【0013】 As shown in Figure 2, the mounting plate 121 is attached to the inside of the pair of vertical frames 11b, 11b of the frame 11 in the width direction. As shown in Figure 1, the front cover 122 covers the outside and top of the shutter curtain 13. The end cover 123 covers the outside in the width direction of the mounting plate 121 (see Figure 2). 【0014】 As shown in Figure 1, the shutter curtain 13 is installed in the opening of the building so as to be openable and closable. A shaft 12a (see Figure 3) is rotatably attached to the mounting plate 121 of the shutter case 12. The upper part of the shutter curtain 13 is connected to the shaft 12a. The shutter curtain 13 can be retracted and extended by the rotation of the shaft 12a. 【0015】 As shown in FIG. 3, the shutter curtain 13 has a plurality of slats 131 and a connecting shaft portion 132. The plurality of slats 131 are arranged adjacent to each other in the vertical direction. The slats 131 have a shape that bulges toward the outdoor side in a vertical cross section along the indoor-outdoor direction. The connecting shaft portion 132 is provided at the upper and lower ends of the slats 131. The connecting shaft portion 132 extends in the width direction. The upper and lower slats 131 are connected to each other so as to be rotatable around the connecting shaft portion 132. 【0016】 As shown in FIG. 1, the guide rails 14 are provided on both sides in the width direction of the opening of the building. The sill 15 is provided at the lower part of the shutter curtain 13. The guide rails 14 guide the width-direction ends of the sill 15 in the vertical direction. 【0017】 Normally, when the shutter curtain 13 is wound up, the sill 15 hits a predetermined position of the manual shutter 100, and the winding up of the shutter curtain 13 is restricted. There are cases where the pair of guide rails 14, 14 and the sill 15 are removed from the manual shutter 100, and a newly installed guide rail (not shown) and a newly installed sill (not shown) provided with a drive mechanism are attached to change the manual shutter 100 to an electric shutter. When the sill 15 is removed from the shutter curtain 13, there is a risk that all the slats 131 will be wound into the shutter case 12. The shutter jig 3 is attached to the both ends in the width direction of the lower slats 131 of the shutter curtain 13 so that all the slats 131 are not wound up. 【0018】 As shown in FIG. 4, the shutter jig 3 has a base portion 31 and a clamping portion 32. The outer shape of the shutter jig 3 is substantially rectangular. The shutter jig 3 is formed of an elastic material such as a soft synthetic resin. The material of the shutter jig 3 can be appropriately set, such as cardboard, an air mat which is a cushioning material utilizing the elasticity of compressed air, etc. 【0019】 The directions in the description of the shutter jig 3 will be described based on the state of being attached to the slats 131. 【0020】 The base portion 31 is roughly rectangular in shape. The base portion 31 protrudes outward in the width direction of the slat 131. 【0021】 The clamping portion 32 extends inward in the width direction from the base portion 31. The clamping portion 32 has a pair of clamping pieces 33, 33. The clamping pieces 33 extend inward in the width direction from the inner end portion 31a of the base portion 31. The pair of clamping pieces 33, 33 are arranged opposite each other, separated in the indoor / outdoor direction. The clamping pieces 33 are rectangular parallelepipeds. The surfaces 331 facing the opposing clamping pieces 33 are vertical surfaces along the width direction. 【0022】 As shown in Figure 3, the pair of clamping pieces 33, 33 clamp the lower slats 131 of the shutter curtain 13 in an in-indoor / out-of-door direction. The shutter jig 3 is attached to the second slat 131 from the bottom, but the shutter jig 3 may be attached to a slat 131 at any other position. 【0023】 Of the pair of clamping pieces 33, 33, the clamping piece 33 positioned on the outdoor side is designated as clamping piece 33a, and the clamping piece 33 positioned on the indoor side is designated as clamping piece 33b. The slat 131 that is sandwiched between the pair of clamping pieces 33a and 33b is designated as slat 131a. Clamping piece 33a protrudes outwards from the slat 131. Clamping piece 33b protrudes inwards from the slat 131. 【0024】 The upper end 133 of the slat 131a is in contact with the upper end 332 of the surface 331 of the clamping piece 33b. The vertical middle portion 134 of the slat 131a is in contact with the vertical middle portion 333 of the surface 331 of the clamping piece 33a. The lower end 135 of the slat 131a is in contact with the lower end 334 of the surface 331 of the clamping piece 33b. The slat 131a is supported and clamped at two points from the indoor side, at the upper end 332 and the lower end 334, and at one point from the outdoor side, at the middle portion 333. 【0025】 The clamping piece 33b corresponds to one of the clamping pieces in the claim. The clamping piece 33a corresponds to the other clamping piece in the claim. The upper end 332 and lower end 334 of the clamping piece 33b correspond to two locations in the claim. The middle portion 333 of the clamping piece 33a corresponds to one location in the claim. 【0026】 When attaching the shutter jig 3 to the slat 131a, the shutter jig 3 is moved from the outside to the inside in the width direction of the shutter curtain 13, and the slat 131a is inserted and clamped between the pair of clamping pieces 33, 33. When the width direction end of the slat 131a hits the width direction inner end 31a (see Figure 4) of the base 31 of the shutter jig 3, the slat 131a and the pair of clamping pieces 33, 33 are positioned. Alternatively, the shutter jig 3 may be used to insert and clamp the lowest slat 131a of the shutter curtain 13 between the pair of clamping pieces 33, 33 from below. 【0027】 To remove the shutter fixture 3 from the shutter curtain 13, move the shutter fixture 3 from the inside to the outside in the width direction of the slats 131a, and then remove the shutter fixture 3. 【0028】 If the shutter curtain 13 is retracted further than the state shown in Figure 2, the upper surface 31u of the base 31 of the shutter jig 3 will come into contact with the lower end surface 121d of the mounting plate 121. The shutter curtain 13 is restricted from being retracted beyond this position. 【0029】 With the shutter jig 3 attached to the shutter curtain 13, the shutter jig 3 protrudes outward from the shutter curtain 13. The base 31 of the shutter jig 3 contacts the mounting plate 121, thereby restricting the winding of the shutter curtain 13 onto the shaft 12a. 【0030】 The clamping portion 32 of the shutter jig 3 grips the shutter curtain 13 in an indoor-outdoor direction, allowing the shutter jig 3 to be detachably attached to the shutter curtain 13. The shutter jig 3 can be easily attached to and removed from the shutter curtain 13. 【0031】 The shutter curtain 13 is supported from the indoor side by clamping pieces 33b at two points and from the outdoor side by clamping piece 33a at one point. Since the shutter jig 3 clamps the shutter curtain 13 in the indoor and outdoor directions at a total of three points, the shutter jig 3 is firmly attached to the shutter curtain 13, and it is prevented from coming off the shutter jig 3. 【0032】 Since the shutter jig 3 is made of an elastic material, it elastically deforms when it is sandwiching the shutter curtain 13. Even when the shutter jig 3 is attached to the shutter curtain 13, damage to the shutter curtain 13 is suppressed because the shutter jig 3 is made of an elastic material. The shutter jig 3 is firmly attached to the shutter curtain 13. 【0033】 With the shutter jig 3 attached to the shutter curtain 13, the baseboard 15 can be easily replaced with the new baseboard for the electric shutter, resulting in good workability. 【0034】 (Variation 1) Next, the shutter jig according to Modification 1 will be explained, mainly using Figure 5. In the explanation of the modification shown below, the same reference numerals are used for the same components as those described above, and their explanations are omitted. 【0035】 As shown in Figure 5, the length of the outdoor clamping piece 33c of the shutter jig 3A in the indoor-outdoor direction is longer than the length of the outdoor clamping piece 33a of the shutter jig 3 according to this embodiment. 【0036】 With the shutter curtain 13 rolled up, the upper surface 33u of the clamping piece 33c of the shutter jig 3A is in contact with the lower end surface 122d of the front cover 122. The shutter curtain 13 is restricted from being rolled up any further than this position. 【0037】 With the shutter jig 3A attached to the shutter curtain 13, the shutter jig 3A protrudes outward from the shutter curtain 13. The upper surface 33u of the clamping piece 33c of the shutter jig 3A contacts the front cover 122, thereby restricting the winding of the shutter curtain 13 onto the shaft 12a. 【0038】 (Modification 2) Next, the shutter jig according to the modified example 2 will be described mainly with reference to Figure 6. As shown in Figure 6, the clamping portion 32B of the shutter jig 3B has an outdoor-side clamping piece 33d and an indoor-side clamping piece 33e. The surface 331a of the outdoor-side clamping piece 33d that faces the clamping piece 33e is curved so as to be concave towards the outdoors. The surface 331b of the indoor-side clamping piece 33e that faces the clamping piece 33d is curved so as to be convex towards the outdoors. 【0039】 The upper end 133 of the slat 131a is in contact with the upper end 332b of the surface 331b of the clamping piece 33e. The upper part 136 of the slat 131a is in contact with the upper part 336d of the surface 331a of the clamping piece 33d. The vertical middle part 134 of the slat 131a is in contact with the vertical middle part 333b of the surface 331b of the clamping piece 33e. The lower part 137 of the slat 131a is in contact with the lower part 337d of the surface 331a of the clamping piece 33d. The lower end 135 of the slat 131a is in contact with the lower end 334b of the surface 331b of the clamping piece 33e. The slat 131a is supported and clamped at three points from the indoor side: the upper end 332b, the middle section 333b, and the lower end 334b, and at two points from the outdoor side: the upper part 336d and the lower part 337d. 【0040】 The clamping piece 33e corresponds to one of the clamping pieces of the claim. The clamping piece 33d corresponds to the other clamping piece of the claim. The upper end 332b, middle portion 333b, and lower end 334b of the clamping piece 33e correspond to two or more locations of the claim. The upper part 336d and lower part 337d of the clamping piece 33d correspond to one or more locations of the claim. 【0041】 (Variation 3) Next, the shutter jig according to the 3rd modification will be described mainly with reference to Figure 7. As shown in Figure 7, the clamping portion 32C of the shutter jig 3C has an outdoor-side clamping piece 33f and an indoor-side clamping piece 33g. The vertical lengths of the clamping pieces 33f and 33g are longer than the vertical length of the slat 131. The surface 331c of the outdoor-side clamping piece 33f facing the clamping piece 33g is formed by multiple planes to be recessed towards the outdoors. The surface 331d of the indoor-side clamping piece 33g facing the clamping piece 33f is formed by multiple planes to be convex towards the outdoors. 【0042】 The surface 331c of the clamping piece 33f has a first surface portion 341, a second surface portion 342, a third surface portion 343, a fourth surface portion 344, and a fifth surface portion 345. The first surface portion 341 is a vertical surface extending downward from the upper end of the clamping piece 33f. The second surface portion 342 is a plane that gradually slopes towards the outdoors as it extends downward from the lower end of the first surface portion 341. The third surface portion 343 is a vertical surface extending downward from the lower end of the second surface portion 342. The fourth surface portion 344 is a plane that gradually slopes towards the indoors as it extends downward from the lower end of the third surface portion 343. The fifth surface portion 345 is a vertical surface extending downward from the lower end of the fourth surface portion 344. 【0043】 The surface 331d of the clamping piece 33g has a first surface portion 351, a second surface portion 352, a third surface portion 353, a fourth surface portion 354, and a fifth surface portion 355. The first surface portion 351 is a vertical surface extending downward from the upper end of the clamping piece 33g.
