[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a sheet-type shutter device that is installed in an opening E such as an entrance or exit of a building, and the shutter device 1 is configured using various components and devices, such as guide rails 2 provided on the left and right sides of the opening, a shutter curtain 3 made of curtain sheet material 3a, a winding body 4 disposed above the opening and around which the shutter curtain 3 is wound, and an electric opening / closing device 5 that drives the winding body 4 to rotate forward and backward, all of which are conventional.

[0009] The curtain sheet material 3a uses a base fabric such as a woven fabric or nonwoven fabric made from synthetic resin fibers such as polyester or polypropylene, and a strong and flexible pull cloth (sheet material) formed by coating both the front and back sides of the base fabric with a synthetic resin material such as polyvinyl chloride or polypropylene, and the curtain sheet material 3a has a window opening 3b formed therein for forming a window W. The window W can be sized to fit various specifications, such as a standard window with window portions formed on both sides as shown in Figure 1(A), a long window with a slightly narrower left-to-right width as shown in Figures 2(A) and (B), or a wide window with a wider left-to-right width, and a window sheet material 6 made of a light-transmitting (light-transmitting) material is attached to the window opening 3b thus formed.

[0010] In order to provide the window sheet material 6 with strength and flexibility, similar to the curtain sheet material 3a, it is preferable to use a drawn fabric in which a synthetic resin material such as polyvinyl chloride is applied to both the front and back sides of a base fabric, which is a woven fabric or nonwoven fabric made from synthetic resin fibers such as polyester. In this case, if the base fabric 6a is, for example, a plain weave in which warp and weft threads are braided in a cross pattern, the base fabric 6a can be made such that the intervals (mesh) between the warp and weft threads are several to tens of millimeters (for example, about 5 to 15 mm), and the resin material 6b applied to both sides of the base fabric 6a is transparent or translucent, thereby providing strength and flexibility while still providing translucency (light transmission). However, because the window sheet material 6 must be translucent, it is subject to limitations on the base fabric 6a and the resin material 6b to be applied, and as a result, the window sheet material 6 is inevitably inferior in strength to the curtain sheet material 3a. Incidentally, when the resin material 6b used in the window sheet material 6 of this embodiment is polyvinyl chloride, the polyvinyl chloride has heat-welding properties (fusion properties) and is suitable for implementing the present invention, but it goes without saying that the resin material is not limited to polyvinyl chloride as long as it has such heat-welding properties.

[0011] The window sheet material 6 configured in this manner is then attached to the window opening 3b, and in this embodiment, a window frame sheet material 7 is also used. The window frame sheet material 7 has a rectangular frame shape to match the peripheral shape of the window opening 3a, and like the window sheet material 6, it is made of a fabric with a base fabric 7a coated with a resin material 7b. In this case, it is preferable that the resin material 7b be made of the same material as the resin material 6b of the window sheet material 6, and since the window frame sheet material 7 made in this way does not need to be translucent like the window sheet material 6, it is preferable to use a base fabric with a strength such that the mesh spacing of the warp and weft threads is narrower than that of the window sheet material 6, and to use a resin material 7b to be applied that is not translucent, for example by mixing in a fiber material (reinforced fiber material) to improve strength. The window frame sheet material 7 is integrally attached to the peripheral edge of the window sheet material 6 by welding (fusion) means such as heat welding or high frequency (ultrasonic) welding (fusion).

[0012] In this way, the peripheral portion of the window sheet material 6, whose peripheral portion has been reinforced by being integrated with the window frame sheet material 7 by welding X, is sewn (sewing, sewing by machine) to the peripheral portion of the window opening 3b using a patch sewing thread 8, with the window frame sheet material 7 arranged on the back side in the front-to-back direction, thereby forming a translucent window portion W in which the three-layer structure formed by stacking the curtain sheet material 3a, the window sheet material 6, and the window frame sheet material 7 is sewn together.

[0013] In the present embodiment configured as described above, the shutter device 1 is configured as a sheet type shutter curtain 3 using curtain sheet material 3a, and when a window opening 3b is formed in the shutter curtain 3 and a translucent window sheet material 6 is attached to the window opening 3b to give the shutter device 1 a translucent function, the peripheral portion of the window opening 3b in the curtain sheet material 3a has a three-layer structure in which the curtain sheet material 3a, the window sheet material 6, and the window frame sheet material 7 are laminated, and this three-layer structure is sewn together with sewing thread 8, so that the three sheet materials 3a, 6, and 7 are attached as a single unit by sewing, resulting in a strong attachment.

[0014] Furthermore, in this case, the window sheet material 6 and the window frame sheet material 7 are made of the same material and are previously integrated by welding X and sewn to the curtain sheet material 3a with sewing thread 8. As a result, the window sheet material 6 is reinforced by the window frame sheet material 7 and sewn to the curtain sheet material 3a, thereby forming a window portion W with excellent strength. Furthermore, the window frame sheet material 7 is made of a fabric that uses a stronger base fabric and a resin material than the window sheet material 6, so that the window portion W can be made stronger.

[0015] The method for forming the window portion W configured as above is as follows: a welding process X for welding together a window sheet material 6 and a window frame sheet material 7 made of the same material; a sewing step of sewing the welded window sheet material 6 and window frame sheet material 7 to the curtain sheet material 3a; By carrying out each of the steps in order, a light-transmitting window W having excellent strength can be easily formed.

[0016] Of course, the present invention is not limited to the above-described embodiment. In the above-described embodiment, the window sheet material 6 and the window frame sheet material 7 are integrated by welding. However, the present invention can also be implemented by stitching together the laminated portions of the sheet materials 3a, 6, and 7, which are separate and not welded together, as shown in Figure 5(B). [Industrial Applicability]

[0017] The present invention can be used as a window structure and a window forming method in a sheet-type shutter device for buildings that opens and closes openings in buildings such as buildings, houses, and factories. [Explanation of symbols]
