Description

[Technical field]

[0001] The present invention relates to a method for decorating a sheet shutter, and also to a decorated shutter curtain that can be employed with the sheet shutter. [Background technology]

[0002] Sheet shutters, which include a shutter curtain made of a flexible curtain sheet and a winding device for winding up the shutter curtain, are sometimes installed at the entrances and windows of factories, stores, etc. Such sheet shutters are often opened and closed frequently (for example, an average of 10 to 20 times a day). For this reason, if the shutter curtain is decorated with paint or the like (for example, decorations such as a company logo, advertising, and warnings), there is a risk that the paint will crack or peel off due to repeated opening and closing.

[0003] On the other hand, in FIG. 1 and the like of Patent Document 1, a display device for shutter 1 is described that can add various advertising and decorative effects to a slat shutter 4 that is composed of a combination of a plurality of elongated slats. As shown in FIG. 3 and FIG. 4 and the like of the same document, the display device for shutter 1 described in the same document is attached to a roll-up slat shutter 4 that is laid on a building or the like and can be moved up and down by a winding roll. The display device for shutter 1 includes a winding member 8 that is fixed to the lower part of the shutter 4 and has a winding shaft that is urged to rotate in one direction, and a display sheet 2 that is fixed at its lower end to the winding member 8 and at its upper end to a horizontal member 9 located at the upper part of the surface of the shutter 4. When the shutter 4 is lowered, the display sheet 2 that is unwound from the winding member 8 is arranged in parallel on the surface of the shutter 4, and when the shutter 4 is raised, the display sheet 2 is wound up from its lower end by the winding member 8.

[0004] [Patent Document 1] JP 2005-97839 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, the display device 1 for shutters described in Patent Document 1 was difficult to apply to a sheet shutter that is frequently opened and closed. This is because, in this device, the display sheet 2 is wound up by the winding member 8 equipped with a rotationally biased winding shaft every time the shutter 4 is opened and closed, and therefore, when this device is applied to a sheet shutter that is frequently opened and closed, there is a risk that the winding member 8 may be easily damaged. In addition, unlike a slat shutter, in a sheet shutter, the shutter curtain is formed of a flexible curtain sheet, so that in a state where there is a gap between the display sheet 2 and the shutter 4 as in this device, one of the display sheet 2 and the shutter 4 is likely to be displaced or bent relative to the other. And, when the shutter 4 is opened and closed in this state, the display sheet 2 is not properly wound up by the winding member 8, which may result in problems with winding up the shutter 4.

[0006] The present invention has been made to solve the above problems, and provides a method for decorating a sheet shutter that can provide a durable decoration to the sheet shutter. Another object of the present invention is to provide a decorative shutter curtain that is provided with a durable decoration. [Means for solving the problem]

[0007] The above issues are: A method for decorating a sheet shutter, comprising: a shutter curtain formed of a flexible curtain sheet; and a winding device for winding up the shutter curtain into a roll; a cutting step of cutting the decorative sheet into a plurality of sheet pieces by making cuts in the decorative sheet; a bonding process in which the plurality of sheet pieces cut in the cutting process are bonded to a curtain sheet; By going through When the shutter curtain is rolled up by a roll-up device, any misalignment in the surface direction that occurs between the decorative sheet and the curtain sheet can be eliminated by the gaps between the multiple sheet pieces. How to decorate sheet shutters This is solved by providing

[0008] This allows for a durable decoration to be applied to, for example, an existing sheet shutter. In other words, if an unslit decorative sheet (a single piece that is not cut into multiple sheet pieces) is attached to a curtain sheet (shutter curtain), when the shutter curtain is rolled up into a roll by a winding device and curved, a misalignment occurs between the decorative sheet and the curtain sheet in the planar direction. Then, when the shutter curtain is lowered again after that, the decorative sheet and the curtain sheet that were arranged on the outside when rolled up will sag relative to the one that was arranged on the inside. If this is repeated, the decorative sheet may become more prone to wrinkles or to peel off from the curtain sheet.

[0009] In this regard, in the sheet shutter decoration method according to the present invention, the decorative sheet is cut into a number of sheet pieces in the cutting step, and the sheet pieces are attached to the curtain sheet in the pasting step (i.e., the decorative sheet that has been cut into pieces is reassembled like a puzzle and pasted onto the curtain sheet). This allows the gaps between the sheet pieces to eliminate any misalignment in the planar direction that occurs between the decorative sheet and the curtain sheet when the shutter curtain is rolled up by the roll-up device, making it difficult for the decorative sheet to wrinkle or peel off from the curtain sheet. Therefore, a highly durable decoration can be applied to a sheet shutter that is frequently opened and closed.

[0010] Even if the decorative sheet (sheet piece) should peel off from the curtain sheet, the risk of the sheet piece getting wrapped around or entangled in the winding device of the sheet shutter is reduced compared to when a single piece of decorative sheet peels off. Furthermore, if the decorative sheet becomes dirty or torn, only the sheet piece in the dirty or torn area can be replaced with a new one, reducing the effort and cost of re-installation.

[0011] In the cutting process, the direction of the cuts in the decorative sheet is not limited. The cuts can include, for example, a plurality of horizontal cuts that are cuts in a direction that is approximately horizontal on the sheet shutter (i.e., a direction that is approximately perpendicular to the rolling up direction of the shutter curtain). This makes it possible to more effectively avoid misalignment in the surface direction that occurs between the decorative sheet and the curtain sheet. In this case, the distance between adjacent horizontal cuts (the distance between two horizontal cuts that are adjacent to each other in the approximately vertical direction on the sheet shutter) is not limited. However, if the distance between adjacent horizontal cuts is too narrow, the sheet piece may become too thin (small), which may make the sheet piece more likely to peel off, and if the distance between adjacent horizontal cuts is too wide, it may become difficult to avoid misalignment between the decorative sheet and the curtain sheet. For this reason, it is preferable that the distance between adjacent horizontal cuts is 10 mm or more and 50 mm or less.

[0012] In the cutting process, the decorative sheet can also be cut so that the multiple sheet pieces are in a generally polygonal shape with a maximum width of 50 mm or less. This allows the planar misalignment between the decorative sheet and the curtain sheet to be eliminated in various directions, making the decorative sheet less likely to wrinkle and less likely to peel off from the curtain sheet. In addition, in the unlikely event that a sheet piece does peel off from the curtain sheet, the risk of the sheet piece getting wrapped around or entangled in the winding device of the sheet shutter can be reduced.

[0013] The above problem also A decorative shutter curtain for a sheet shutter, A flexible curtain sheet; Decorative sheet attached to curtain sheet and Equipped with The decorative sheet is cut into multiple sheet pieces along cut lines and attached to the curtain sheet, When the sheet shutter is wound up into a roll by the winding device, any misalignment in the surface direction that occurs between the decorative sheet and the curtain sheet can be eliminated by the gaps between the multiple sheet pieces. Decorative shutter curtains This can also be solved by providing

[0014] In this way, it is possible to provide a decorative shutter curtain with a highly durable decoration. The decorative shutter curtain according to the present invention can be used in a newly manufactured sheet shutter, or can be used as a replacement shutter curtain for an existing sheet shutter. Effect of the Invention

[0015] As described above, the present invention makes it possible to provide a method for decorating a sheet shutter that can provide a durable decoration to the sheet shutter. It also makes it possible to provide a decorative shutter curtain that is provided with a durable decoration. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] A preferred embodiment of the present invention will be described in more detail with reference to the drawings. However, the technical scope of the present invention is not limited to the embodiment described below. In Figs. 1 to 7 shown below, the x-axis, y-axis, and z-axis are shown, and these are consistent between different figures. However, the x-axis, y-axis, and z-axis in Figs. 4 and 5 represent the orientation of the decorative sheet 100 in a state where it is attached to the shutter curtain 10 of the sheet shutter 1, and do not represent the orientation of the decorative sheet 100 before attachment or the orientation of the decorative shutter curtain 10 before it is attached to the sheet shutter 1. In the following, for convenience of explanation, the x-axis direction may be expressed as "left and right", the negative y-axis direction as "foreground", the positive y-axis direction as "back", the positive z-axis direction as "top", and the negative z-axis direction as "bottom".

[0018] 1. First embodiment Fig. 1 is a front view showing a state in which a sheet shutter 1 installed at the entrance of a factory is decorated. Fig. 2 is a cross-sectional view showing the sheet shutter 1 of Fig. 1 cut along a vertical plane that is approximately perpendicular to the shutter curtain 10. Fig. 3 is a diagram showing a state in which the shutter curtain 10 has been rolled up by a winding device 20 from the state shown in Fig. 2.

[0019] As the first embodiment, a sheet shutter decoration method for decorating a sheet shutter 1 already installed at the entrance of a factory is taken as an example. As shown in FIG. 2, the sheet shutter 1 includes a shutter curtain 10 formed of a flexible curtain sheet 11 and a winding device 20 for winding up the shutter curtain 10 in a roll shape. As shown in FIG. 1, a plurality of long support members 30 (metallic pipes in this embodiment) are attached to the shutter curtain 10 at equal intervals in the vertical direction. More specifically, as shown in the enlarged portion of FIG. 2, a support member accommodating section 12 formed in a bag shape long in the left-right direction (in FIG. 2, the direction substantially perpendicular to the paper surface) is attached to the curtain sheet 11 of the shutter curtain 10, and the support member 30 is accommodated in the support member accommodating section 12. The support member accommodating section 12 is attached to the curtain sheet 11 only at its upper part, and the support member 30 can move to a certain extent relative to the curtain sheet 11. Both ends of the support member 30 are attached to guide rails (not shown) provided on the left and right sides of the sheet shutter 1.

[0020] In this embodiment, as shown in Fig. 1, decoration is performed by attaching a decorative sheet 100 to the shutter curtain 10 of this sheet shutter 1. Specifically, the shutter curtain 10 is decorated through a cutting process in which the decorative sheet 100 is cut into a plurality of sheet pieces 200 by making cuts 110 in the decorative sheet 100, and an attaching process in which the plurality of sheet pieces 200 cut in the cutting process are attached to the curtain sheet 11 of the shutter curtain 10.

[0021] In the sheet shutter 1 decorated by such a decoration method, as shown in the enlarged view of Fig. 1, the decorative sheet 100 is cut into a plurality of sheet pieces 200 by slits 110 and attached to the curtain sheet 11 of the shutter curtain 10. As a result, as shown in Fig. 3, when the shutter curtain 10 is rolled up by the roll-up device 20, the slits 110 between the plurality of sheet pieces 200 can eliminate the misalignment in the planar direction that occurs between the decorative sheet 100 (sheet piece 200) and the curtain sheet 11 (i.e., as shown in the enlarged portion of Fig. 3, the slits 110 widen to eliminate the misalignment in the planar direction). Therefore, even if the sheet shutter 1 is frequently opened and closed, the decorative sheet 100 is less likely to wrinkle and is less likely to peel off from the curtain sheet 11.

[0022] Each step included in the decoration method of this embodiment will be described in detail below.

[0023] 1.1 Cutting process FIG. 4 is a diagram showing a pattern of cuts 110 to be made in the decorative sheet 100 in the first embodiment. In this embodiment, a first color sheet 100a shown in FIG. 4(a) and a second color sheet 100b shown in FIG. 4(b) are used in combination as the decorative sheet 100. The first color sheet 100a and the second color sheet 100b are different in color, and when the decorative sheet 100 is attached to the curtain sheet 11 of the shutter curtain 10 in the attachment step described below, the first color sheet 100a and the second color sheet 100b are arranged so that the second color sheet 100b borders the outside of the first color sheet 100a, as shown in FIG. 1. This makes it possible to express the letter "K" with a border.

[0024] In the cutting step, as shown in Figs. 4(a) and 4(b), cuts 110 are made in the decorative sheet 100 (in this embodiment, the first color sheet 100a and the second color sheet 100b) to cut the decorative sheet 100 into a plurality of sheet pieces 200. The pattern (number, direction, interval, etc.) of the cuts 110 made in the decorative sheet 100 is not particularly limited. In this embodiment, as shown in Fig. 4, horizontal cuts 111, which are cuts in a direction that will be approximately horizontal after attachment to the sheet shutter 1, are made at multiple locations at intervals in the vertical direction (the direction that will be vertical after attachment to the sheet shutter 1). This makes it possible to more effectively avoid misalignment in the surface direction between the decorative sheet 100 (sheet piece 200) and the curtain sheet 11 that occurs when the shutter curtain 10 is rolled up by the roll-up device 20.

[0025] The distance W1 (FIGS. 1 and 4) between adjacent horizontal cuts 111 is not particularly limited. However, if the distance W1 is too narrow, the sheet piece 200 may become too thin and may be easily peeled off. For this reason, the distance W1 is preferably 10 mm or more. The distance W1 is more preferably 15 mm or more, and even more preferably 20 mm or more. On the other hand, if the distance W1 is too wide, it may become difficult to prevent the decorative sheet 100 and the curtain sheet 11 from shifting. For this reason, the distance W1 is preferably 50 mm or less. The distance W1 is more preferably 45 mm or less, and even more preferably 40 mm or less. In this embodiment, the distance W1 is set to about 25 to 30 mm.

[0026] The distance W1 between adjacent horizontal cuts 111 may be the same or different between all horizontal cuts 111. In this embodiment, the distance W1 is made substantially the same between all horizontal cuts 111. In other words, the horizontal cuts 111 are arranged at substantially equal intervals in a substantially vertical direction on the sheet shutter 1.

[0027] In addition, in this embodiment, the distance W1 (FIGS. 1 and 2) between adjacent horizontal cuts 111 is set so that the distance W1 is a length obtained by dividing the distance W2 (FIGS. 1 and 2) between adjacent support members 30 in the shutter curtain 10 of the sheet shutter 1 by an integer. In other words, the distance W1 is determined so that the distance W2 between the support members 30 of the sheet shutter 1 to be decorated is an integer multiple of the distance W1 between adjacent horizontal cuts 111. The reason for this will be explained later.

[0028] In this embodiment, as shown in Fig. 4, each of the first color sheet 100a and the second color sheet 100b has only one vertical cut 110 (z-axis direction in Fig. 4). This is because the first color sheet 100a and the second color sheet 100b are two sheets each having a width of about 1000 mm (indicated by a broken line in Fig. 4) that are arranged horizontally, and the seam between the sheets remains as the cut 110.

[0029] Fig. 5 is a diagram showing another example of the pattern of the slits 110 made in the decorative sheet 100. In this embodiment, as shown in Fig. 4, the decorative sheet 100 has multiple slits 110 (horizontal cuts 111) that are approximately horizontal on the sheet shutter 1 and spaced at equal intervals with a distance W1 between them. In another embodiment, as shown in Fig. 5(a), multiple slits 110 that are approximately vertical on the sheet shutter 1 can also be made at equal intervals. In this case, the sheet piece 200 has a long tape-like shape.

[0030] Alternatively, as shown in Fig. 5(b) to (l), the cuts 110 can be made so that the sheet pieces 200 are in a generally polygonal shape with a maximum width of 50 mm or less. That is, the decorative sheet 100 can be cut into relatively small sheet pieces 200 like a puzzle. The shutter curtain 10 of the sheet shutter 1 is formed of a flexible curtain sheet 11, and therefore can be curved in any direction, not just the up-down direction. In this regard, by cutting the decorative sheet 100 into a puzzle shape, it is possible to easily avoid any misalignment in the planar direction between the curtain sheet 11 and the decorative sheet 100, even if the curtain sheet 11 is curved in various directions.

[0031] In this case, the maximum width of the sheet piece 200 (when the sheet pieces 200 include sheet pieces 200 of multiple shapes or sizes, the maximum width of the sheet piece 200 with the largest maximum width; the same applies below) is not limited as long as it is 50 mm or less. From the viewpoint of more effectively releasing the misalignment in the planar direction, the maximum width of the sheet piece 200 is more preferably 40 mm or less, and even more preferably 30 mm or less. However, if the sheet piece 200 is too small, the sheet piece 200 may be easily peeled off from the curtain sheet 11. For this reason, the maximum width of the sheet piece 200 is preferably 10 mm or more, more preferably 20 mm or more, and even more preferably 25 mm or more. When the sheet pieces 200 include sheet pieces 200 of multiple shapes or sizes, the maximum width of the sheet piece 200 with the smallest maximum width is preferably 10 mm or more, more preferably 20 mm or more, and even more preferably 25 mm or more.

[0032] In the case where the sheet pieces 200 are made to have an approximately polygonal shape with a maximum width of 50 mm or less, the shape of each sheet piece 200 is not particularly limited as long as the sheet pieces 200 as a whole can cover a plane. The sheet pieces 200 can be, for example, triangular, rectangular, pentagonal, hexagonal, octagonal, etc. In the case where the sheet pieces 200 are made to have an approximately polygonal shape, it is preferable that the size of the smallest one of the interior angles (hereinafter, sometimes referred to as the "minimum interior angle") is 30° or more. This makes it possible to make the sheet pieces 200 less likely to peel off. The minimum interior angle of the sheet pieces 200 is more preferably 50° or more, and even more preferably 60° or more. The upper limit of the minimum interior angle of the sheet pieces 200 is not particularly limited, but is usually less than 180°.

[0033] When the sheet pieces 200 are made to have a substantially polygonal shape with a maximum width of 50 mm or less, the multiple sheet pieces 200 may be substantially all of the same shape, for example, as illustrated in Figures 5(b) to (j). In other words, 90% or more of the total area of ​​the decorative sheet 100 may be occupied by sheet pieces 200 of substantially the same shape. Alternatively, the multiple sheet pieces 200 may be a combination of two or more different types of sheet pieces 200 of different polygonal shapes, as illustrated in Figures 5(k) and (l).

[0034] Even when the sheet piece 200 has a generally polygonal shape with a maximum width of 50 mm or less, it is preferable to employ horizontal cuts 111 made in a plurality of locations at equal intervals at a predetermined distance W1 (FIGS. 1 and 2) as part of the slits 110 made in the cutting process (i.e., as part of the sides of the generally polygonal sheet piece 200), as exemplified in Figures 5(b)-(f),(h),(k), and(l). This makes it possible to effectively prevent misalignment in the planar direction between the decorative sheet 100 and the curtain sheet 11 when the shutter curtain 10 is rolled up by the roll-up device 20.

[0035] When the sheet piece 200 has a generally polygonal shape with a maximum width of 50 mm or less, the slits 110 made in the decorative sheet 100 may be partially or entirely meandering, as shown in Figs. 5(c), (h) to (k). In this case, however, the work of making the slits 110 may become complicated. Therefore, in the examples shown in Figs. 5(b), (d) to (g), and (l), generally all of the slits 110 are linear and cut across the decorative sheet 100. This makes it easier to make the slits 110. Here, "cutting across the decorative sheet 100" means penetrating the decorative sheet 100 from one end to the other, and is not limited to running in a specific direction.

[0036] In the examples shown in Fig. 5(b), (d) to (g), and (l), lattice-shaped slits 110 are used. That is, two or more sets of multiple slits 110 arranged parallel to each other and at approximately equal intervals are overlapped with different orientations (angles). This makes it easier to make the sheet pieces 200 uniform in size, and makes it more difficult for the sheet pieces 200 to peel off. In addition, the pattern of the slits 110 can be simplified.

[0037] There are no particular limitations on the method for making the cuts 110 in the decorative sheet 100. The cuts 110 may be made manually, for example, with a knife, or may be made automatically (mechanically) with a mechanical cutter, laser cutter, or the like.

[0038] 1.2 Pasting process In the attachment process of this embodiment, first, the area of ​​the shutter curtain 10 where the decorative sheet 100 is to be attached is cleaned. This removes any dirt or stains adhering to the curtain sheet 11, making it more difficult for the decorative sheet 100 (sheet piece 200) to peel off from the curtain sheet 11. The cleaning is performed using a neutral detergent, an organic solvent, or the like, depending on the material of the curtain sheet 11. The curtain sheet 11 in this embodiment is made of polyvinyl chloride resin, and cleaning was performed using a diluted neutral detergent.

[0039] Next, the position on the shutter curtain 10 where the decorative sheet 100 is to be attached is determined. There are no particular limitations on the positioning method, but in this embodiment, positioning is performed by attaching a paper positioning sheet to the shutter curtain 10 using masking tape or the like. When attaching the decorative sheet 100 to the shutter curtain 10, this positioning sheet is used as a guide. The positioning sheet is not limited to being made of paper, and may be formed of other materials (for example, resin, cloth, etc.).

[0040] Once positioning is complete, the multiple sheet pieces 200 cut in the cutting process are attached to the curtain sheet 11 of the shutter curtain 10 while maintaining the arrangement before cutting. As a result, as shown in Fig. 1, the multiple sheet pieces 200 form one unified display (in Fig. 1, a display showing the alphabet letter "K") Note that the expression "while maintaining the arrangement before cutting" also includes the case where the multiple sheet pieces 200 include multiple pieces that are approximately the same in size, shape, and color and pattern, and these approximately identical sheet pieces 200 are replaced and attached.

[0041] In the sheet shutter 1 decorated in this embodiment, as already described, the support member 30 (enlarged portion in FIG. 2) is attached to the shutter curtain 10 while being housed in the support member housing portion 12. When attaching the decorative sheet 100 (sheet piece 200) to the portion of the shutter curtain 10 where the support member 30 is attached, the support member 30 is made to protrude from between the horizontal cuts 111 of the decorative sheet 100, as shown in the enlarged portion in FIG. 2. In other words, the sheet piece 200 (upper support member piece 210) disposed immediately above the support member 30 does not overlap (does not overlap) at least the lower half of the support member 30 (the portion below the center in the vertical direction). The lower half of the support member 30 is a portion that is subject to friction when the shutter curtain 10 is rolled up by the winding device 20, so by avoiding this portion when attaching the decorative sheet 100 (sheet piece 200), it is possible to more effectively prevent the decorative sheet 100 from wrinkling or peeling off. In addition, in this case, the sheet piece 200 (support member lower piece 220) directly below the support member upper piece 210 is attached to the curtain sheet 11 while being recessed into the back side of the support member housing portion 12. This makes it possible to prevent the arrangement of the support member upper piece 210 and the support member lower piece 220 from becoming distorted.

[0042] Furthermore, when the decorative sheet 100 straddles multiple support members 30, as described above, it is preferable to set the distance W1 (FIGS. 1 and 2) between the horizontal cuts 111 made in the decorative sheet 100 to a length obtained by dividing the distance W2 (FIGS. 1 and 2) between adjacent support members 30 by an integer. This makes it easier to align the positional relationship of the upper support member piece 210 and the lower support member piece 220 with respect to the support members 30 between the support members 30, and makes it easier to protrude each of the multiple support members 30 from between the horizontal cuts 111 in the decorative sheet 100.

[0043] After the decorative sheet 100 (sheet piece 200) has been attached, the surface of the attached decorative sheet 100 is cleaned. The cleaning can be carried out, for example, using a diluted neutral detergent. This completes the attachment process. Note that, although this embodiment has been described as an example in which the decorative sheet 100 is attached to the front surface of the sheet shutter 1 (the surface that is placed outside the building), the decorative sheet 100 may also be attached to the rear surface of the sheet shutter 1 (the surface that is placed inside the building).

[0044] 1.3 Decorative sheets

[0045] In this embodiment, as shown in Fig. 4, the first color sheet 100a and the second color sheet 100b of the decorative sheet 100 are each cut so that the letter "K" is displayed as a whole (i.e., the display is made by the external shape of the decorative sheet 100). However, the display method of the decorative sheet 100 is not particularly limited. For example, the decorative sheet 100 may be displayed by the external shape of a color sheet of one color, or may be displayed by the external shapes of color sheets of three or more colors. The decorative sheet 100 may also be displayed by printing or painting applied to a base sheet.

[0046] The decorative sheet 100 is not particularly limited in terms of its material, so long as it is in the form of a flexible sheet. For example, a resin sheet, a paper sheet, a cloth sheet, a metal sheet, etc. can be used as the decorative sheet 100. Among them, a resin sheet is preferable because it is easy to increase the durability of the decorative sheet 100 itself. Examples of resins that form the resin sheet include polyvinyl chloride, polyolefins (for example, polyethylene, ethylene-vinyl acetate copolymer resin, polypropylene, etc.), and polyethylene terephthalate. The resin sheet can be formed of only one type of resin, or two or more types of resins in combination. The resin sheet can also have a multi-layer structure formed of different types of resins. In this embodiment, a polyvinyl chloride resin sheet is used as the decorative sheet 100. This can increase the weather resistance of the decorative sheet 100.

[0047] The tensile elongation of the decorative sheet 100 (measured in accordance with JIS K7127 using a tensile tester under the following conditions: test piece width 25 mm, grip distance 100 mm, tensile speed 300 mm / min, temperature 20°C, and humidity 65%; the same applies below) is preferably 110% or more, and more preferably 115% or more. This allows the decorative sheet 100 (sheet piece 200) to withstand a certain degree of elongation, and when the curtain sheet 11 is curved, it can easily follow the curvature. However, if the tensile elongation of the decorative sheet 100 is too large, the dimensions of the decorative sheet 100 (sheet piece 200) may become distorted. For this reason, the tensile elongation of the decorative sheet 100 is preferably 130% or less, and more preferably 125% or less. The tensile elongation of the decorative sheet 100 in this embodiment is about 120%.

[0048] In this embodiment, the decorative sheet 100 is a resin sheet having an adhesive layer (not shown) laminated on one side thereof. The type of adhesive forming the adhesive layer is not particularly limited. The adhesive may be an acrylic adhesive, a rubber adhesive, a silicone adhesive, or the like. In this embodiment, a pressure-sensitive permanent acrylic adhesive is used. This can improve the weather resistance and heat resistance of the adhesive layer. The adhesive may be either colored or uncolored (transparent).

[0049] The adhesive strength of the adhesive layer (not shown) of the decorative sheet 100 (adhesive strength measured on an acrylic plate with a width of 25 mm at a temperature of 20°C and a humidity of 65%, in accordance with JIS Z0237; the same applies below) is preferably 15 N or more. This makes it possible to make the decorative sheet 100 (sheet piece 200) less likely to peel off. The adhesive strength of the adhesive layer is more preferably 20 N or more, and even more preferably 23 N or more. There is no particular upper limit for the adhesive strength of the adhesive layer, but it is usually set to 40 N or less. The adhesive strength of the adhesive layer of the decorative sheet 100 in this embodiment is about 25 N.

[0050] The thickness of the decorative sheet 100 is not particularly limited. However, if the decorative sheet 100 is too thick, the decorative sheet 100 (sheet piece 200) may have difficulty following the curvature of the curtain sheet 11 and may be easily peeled off. For this reason, the thickness of the decorative sheet 100 (including the adhesive layer, measured in accordance with JIS K7130; the same applies below) is preferably 0.3 mm or less, and more preferably 0.1 mm or less. On the other hand, if the decorative sheet 100 is too thin, the decorative sheet 100 (sheet piece 200) may be easily twisted or wrinkled. For this reason, the thickness of the decorative sheet 100 is preferably 0.03 mm or more, and more preferably 0.06 mm or more. The thickness of the decorative sheet 100 in this embodiment is about 0.08 mm.

[0051] Incidentally, if the vertical width W3 of the decorative sheet 100 (the vertical width before being cut in the cutting process; see FIG. 4; the same applies below) is sufficiently small, even if the decorative sheet 100 is not cut into the sheet pieces 200 in the cutting process (even if the decorative sheet 100 is attached to the curtain sheet 11 as a single piece), there is little risk of the decorative sheet 100 wrinkling or peeling off from the curtain sheet 11. For this reason, it is preferable that the vertical width W3 of the decorative sheet 100 is 100 mm or more. This enhances the significance of cutting the decorative sheet 100 into the sheet pieces 200. It is more preferable that the vertical width W3 of the decorative sheet 100 is 200 mm or more, and more preferably 300 mm or more. The upper limit of the vertical width W3 of the decorative sheet 100 depends on the vertical width of the shutter curtain 10 and is not limited, but is usually set to 8000 mm or less.

[0052] In the above, an example of a decoration method for decorating an existing sheet shutter 1 has been described. However, a newly decorated shutter curtain 10 can also be manufactured using the same procedure as in this embodiment. The manufactured decorated shutter curtain 10 can be used as part of a newly manufactured sheet shutter 1, or can be used as a replacement shutter curtain for an existing sheet shutter 1.

[0053] 2. Second embodiment 6 is a cross-sectional view showing a sheet shutter 1 employing a decorative shutter curtain 10 of the second embodiment, cut along a vertical plane that is substantially perpendicular to the shutter curtain 10. As the second embodiment and a third embodiment described later, a decorative shutter curtain 10 that can be employed in the sheet shutter 1 will be given as an example.

[0054] In the above-mentioned first embodiment, as shown in the enlarged portion of Fig. 2, decoration is provided by attaching a decorative sheet 100 (sheet piece 200) to the outside of the shutter curtain 10. In contrast, in the decorated shutter curtain 10 of the second embodiment, as shown in Fig. 6, the decorative sheet 100 (sheet piece 200) is attached to the inside of the shutter curtain 10.

[0055] That is, as shown in Fig. 6, the decorative shutter curtain 10 of the second embodiment has, as curtain sheets 11, a front curtain sheet 11a and a rear curtain sheet 11b overlapping the rear side of the front curtain sheet 11a. The decorative sheet 100 (sheet piece 200) is attached to the inside (rear side) of the front curtain sheet 11a. The front curtain sheet 11a is formed of a transparent or semi-transparent flexible sheet, so that the decorative sheet 100 can be seen from the front side of the shutter curtain 10. In this case, when an adhesive layer (not shown) is provided on the decorative sheet 100, it is preferable to use a transparent adhesive.

[0056] In this way, in the second embodiment, the decorative sheet 100 is sandwiched between the front curtain sheet 11a and the rear curtain sheet 11b. This makes it possible to make the decorative sheet 100 (sheet pieces 200) less likely to peel off. It also makes it possible to make the decorative sheet 100 less likely to get scratched or dirty. In FIG. 6, the decorative sheet 100 is attached to the inside (rear side) of the front curtain sheet 11a, but the decorative sheet 100 may also be attached to the inside (front side) of the rear curtain sheet 11b.

[0057] The rear curtain sheet 11b may be transparent, semi-transparent, or opaque. The thickness of the front curtain sheet 11a is preferably thinner than the thickness of a general curtain sheet 11 (about 1.5 mm to 2 mm). The thickness of the front curtain sheet 11a is preferably 1.2 mm or less, and more preferably 1 mm or less. However, if the thickness of the front curtain sheet 11a is too thin, it may be difficult to obtain the desired strength. For this reason, the thickness of the front curtain sheet 11a is preferably 0.2 mm or more, and more preferably 0.5 mm or more. The thickness of the rear curtain sheet 11b may also be the same as that of the front curtain sheet 11a. The thickness of the front curtain sheet 11a and the thickness of the rear curtain sheet 11b may be approximately the same or different.

[0058] Other than this, the same configuration as that described in the first embodiment can be adopted.

[0059] 3. Third embodiment Fig. 7 is a cross-sectional view showing a sheet shutter 1 employing a decorative shutter curtain 10 of the third embodiment, cut along a vertical plane substantially perpendicular to c. As shown in Fig. 7, the decorative shutter curtain 10 of the third embodiment has, as curtain sheets 11, a front curtain sheet 11a, a middle curtain sheet 11c overlapping the back side of the front curtain sheet 11a, and a back curtain sheet 11b overlapping the back side of the middle curtain sheet 11c. The front curtain sheet 11a and the back curtain sheet 11b are formed of transparent or semi-transparent flexible sheets, and the middle curtain sheet 11c is formed of an opaque flexible sheet.

[0060] A front decorative sheet 100c for displaying on the front side is attached to the inside (rear side) of the front curtain sheet 11a, and a rear decorative sheet 100d for displaying on the rear side is attached to the inside (rear side) of the middle curtain sheet 11c. Since the middle curtain sheet 11c is opaque, the front decorative sheet 100c cannot be seen from the rear side, and the rear decorative sheet 100d cannot be seen from the front side. That is, the decorated shutter curtain 10 of the third embodiment can display different things on the front side and the rear side. For example, a company logo or an advertisement can be displayed on the front side. For example, a warning to employees can be displayed on the rear side. The front decorative sheet 100c can also be attached to the front side of the middle curtain sheet 11c. The rear decorative sheet 100d can also be attached to the inside (front side) of the rear curtain sheet 11b.

[0061] In addition, in the third embodiment, a heat insulating film 300 is attached to the intermediate curtain sheet 11c. This makes it possible to make it difficult for heat in the space in front of the decorative shutter curtain 10 to be transmitted to the space behind it, thereby improving, for example, air conditioning efficiency. In this embodiment, as shown in FIG. 7, the heat insulating film 300 is also attached to the intermediate curtain sheet 11c in a state in which it is cut into a plurality of pieces by slits 310 (in a puzzle shape), similar to the decorative sheet 100. This makes it possible to make the heat insulating film 300 less likely to twist or peel off. For example, a Low-E film in which a metal sputtering coating is laminated on a resin film can be used as the heat insulating film 300.

[0062] In FIG. 7, the heat insulating film 300 is attached to the front side of the intermediate curtain sheet 11c, but there is no limitation on where the heat insulating film 300 is attached to the curtain sheet 11. For example, the heat insulating film 300 can be attached to the outside (near side) or inside (rear side) of the front curtain sheet 11a, the rear side of the intermediate curtain sheet 11c, or the inside (near side) or outside (rear side) of the rear curtain sheet 11b. In addition, in the same figure, the slit 110 of the front decorative sheet 100c, the slit 310 of the heat insulating film 300, and the slit 110 of the rear decorative sheet 100d are approximately aligned in the vertical direction, but these positions may be offset from each other. Other configurations may be the same as those described in the first or second embodiment. [Explanation of symbols]
