[Basic structure of lattice sheet material]
As shown in FIG. 1, the lattice-shaped sheet material 1 according to the present embodiment intersects a plurality of vertical bands 10 extending in a predetermined direction (first direction X) and the extending direction of the vertical bands 10. A plurality of horizontal bands 20 extending in a direction (second direction Y) are assembled in a lattice shape (see FIG. 2A). In FIG. 1, four vertical belts 10 and horizontal belts 20 are shown for explanation, but the number corresponding to the size of the lattice-like sheet material 1 is used. Therefore, the numbers of the vertical band 10 and the horizontal band 20 are not particularly limited.

  Each of the vertical bands 10 is formed with upper slits 11a and 11b extending downward from the upper edge and lower slits 12a and 12b extending upward from the lower edge. The upper slits 11a and 11b and the lower slits 12a and 12b (hereinafter simply referred to as “slits” unless otherwise distinguished) are alternately formed in the longitudinal direction of the longitudinal band 10 at a predetermined interval a. The slit has a length Wd1 that reaches the approximate center of the width W1 of the vertical belt 10. Moreover, although the formation position of the slit formed in the longitudinal belt 10 is the same in the adjacent longitudinal belt 10, the kind is different. More specifically, a slit located at the same position in the longitudinal direction of the vertical belt 10 has a lower slit formed on one vertical belt 10 and an upper slit formed on the other adjacent vertical belt 10. ing.

  Similarly to the vertical belt 10, the horizontal belt 20 has upper slits 21 a and 21 b extending downward from the upper edge and lower slits 22 a and 22 b extending upward from the lower edge with a predetermined distance b in the length direction of the horizontal belt 20. Are formed alternately. Similarly to the vertical band 10, the slits at the same position in the length direction of the horizontal band 20 are different in the type of the adjacent horizontal band 20. That is, in the lattice-shaped sheet material 1 according to the present embodiment, different slits are alternately arranged in the first direction X and the second direction Y. In addition, the slit formed in the horizontal band 20 has a length Wd2 that reaches the approximate center of the width W2 of the horizontal band.

  Next, how to assemble the vertical belt 10 and the horizontal belt 20 in which slits are formed will be described. The lower slit 22a of the horizontal band 20a is aligned with the upper slit 11a of the vertical band 10a from above, and the slits 11a and 22a are inserted into the vertical band 10a and the horizontal band 20a. Further, the upper slit 21a of the horizontal band 20a is inserted into the lower slit 12a of the vertical band 10b from below. The mutual slits 12a and 21a are inserted into the vertical band 10b and the horizontal band 20a. Similarly, the lower slit 22b of the horizontal band 20a is inserted from above into the upper slit 11b of the vertical band 10c, and the upper slit 21b of the horizontal band 20a is inserted from below into the lower slit 12b of the vertical band 10d. In this way, the vertical belt 10 and the horizontal belt 20 are assembled with the vertical belt 10 and the horizontal belt 20 being alternated for each slit position. And the lattice-shaped sheet material 1 is assembled by assembling all the vertical strips 10 and the horizontal strips 20.

  The lattice-shaped sheet material 1 assembled in this way is shown in FIG. Slits 11a, 11b, 12a, 12b, 21a, 21b, 22a, and 22b are formed at each intersection of the vertical belt 10 and the horizontal belt 20, and these slits are in a state where the other belt body is inserted. Yes. Therefore, the slit interval between the vertical belt 10 and the horizontal belt 20 determines the mesh size of the lattice-shaped sheet material 1.

  Further, the lattice-shaped sheet material 10 is configured such that the vertical belt 10 and the horizontal belt 20 are alternated for each slit formed in the vertical belt 10 and the horizontal belt 20. Therefore, the state in which the vertical belt 10 and the horizontal belt 20 are combined does not easily come off.

  In the lattice-like sheet material 1 having such a configuration, the vertical belt 10 and the horizontal belt 20 are selected from various materials, and the dimensions (width, thickness, length) of the vertical belt 10 and the horizontal belt 20 and the interval between the slits. By appropriately setting etc., a sheet material having various functions can be obtained. As shown in FIG. 2 (b), in the lattice-like sheet material according to the present embodiment, the width of the slit 11c formed in the vertical band 10d is wider than the thickness of the crossing horizontal band 20b (this is The relationship between the slit of the band 20 and the thickness of the vertical band 10 is the same). Therefore, the direction (intersection angle) of the horizontal band 20b can be freely changed in the slit 11c formed in the vertical band 10d (FIG. 2C). The crossing angle that can be changed means not only the crossing angle between the vertical belt 10d and the horizontal belt 20b when the lattice-like sheet material is viewed in plan, as shown in FIG. It is assumed that the band 10d and the horizontal band 20b include a crossing angle that changes three-dimensionally so as to cause a twist at the slit position. Hereinafter, examples in which the grid sheet material 1 according to the present embodiment is used for various articles will be described.

[Example 1]
In this example, a lattice-shaped sheet material according to an embodiment of the present invention is applied to a blind. FIG. 3 is a plan view of a blind using a grid-like sheet material according to an embodiment of the present invention, and FIG. 4 is a diagram showing a blind using a grid-like sheet material according to an embodiment of the present invention. (a) is a plan view of a blind partially formed with a light shielding part, and (b) is an enlarged plan view of the light shielding part indicated by “b” in (a). FIG. 5 is a view showing a blind using the grid sheet material according to the embodiment of the present invention, and is a plan view showing a state in which the end portion is pulled and the light shielding portion returns to the original state. is there.

  This blind 100 has a lattice-like sheet material 101 and a suspending portion 130 that suspends one side of the lattice-like sheet material 101, and is installed in a window frame or the like to reduce the amount of incident external light or the amount of ventilation. adjust. In the lattice-like sheet material 101, the vertical belt 110 and the horizontal belt 120 are made of, for example, a woven fabric (mesh 200) made of polyethylene. The width W1 of the vertical band 110 and the width W2 (FIG. 1) of the horizontal band 120 are both 10 mm, and the slit interval a formed in the vertical band 110 and the slit interval b formed in the horizontal band 120 are both 10 mm. .

  The grid-like sheet material 101 shown in FIG. 3 is in a state where the vertical belt 110 and the horizontal belt 120 are erected. In the present specification, the state in which the vertical belt and the horizontal belt stand up means that the width W1 direction of the vertical belt 10 and the width W2 direction of the horizontal belt 20 face the vertical direction as shown in FIG. In other words, the lattice section 140 of the lattice-like sheet material 1 is clearly formed. That is, in the lattice-like sheet material 101 shown in FIG. 3, the width direction of the vertical band 110 and the horizontal band 120 is perpendicular to the paper surface. Then, the light passes through the lattice section 140 divided by the vertical belt 110 and the horizontal belt 120 and is ventilated.

  FIG. 4A shows the blind 100 in which the surface is traced by hand and the light shielding part 150 is formed on the lattice-like sheet material 101. As described above, the lattice-like sheet material 101 is made of a woven fabric made of polyethylene, and is soft and light. Therefore, when the surface of the grid-like sheet material 101 is traced by hand, the vertical band 110 and the horizontal band 120 in the traced range change from the standing state to the collapsed state (FIG. 4A). In this specification, the state in which the vertical belt 110 and the horizontal belt 120 are collapsed is a state in which the width direction of the vertical belt 110 and the horizontal belt 120 faces the plane direction of the lattice-like sheet material 101 and overlaps in a plane ( This refers to FIG. In addition, since the flexibility of the vertical belt 110 and the horizontal belt 120 is excellent, the restoring elastic force which tries to return to the original standing state from being traced by hand is weak. For this reason, the vertical belt 110 and the horizontal belt 120 in the region traced by the hand are held in a state of being tilted. As described above, when the vertical belt 110 and the horizontal belt 120 are collapsed, the vertical belt 110 and the horizontal belt 120 block the lattice section 140 formed on the lattice-like sheet material 101 as shown in FIG. become.

  As described above, the light shielding unit 150 in the state in which the vertical belt 110 and the horizontal belt 120 are tilted functions as a non-venting portion that blocks the incidence of external light and blocks ventilation. Further, the periphery of the light shielding portion 150 is a region where the vertical belt 110 and the horizontal belt 120 are erected, and functions as a light transmitting portion that transmits external light and also functions as a ventilation portion that allows ventilation.

  When the end portion is pulled as shown by an arrow in FIG. 5 in a state where the light shielding portion 150 is formed on a part of the lattice-like sheet material 101, the vertical belt 110 and the horizontal belt 120 are tense and the vertical belt 110 that has been tilted is collapsed. And the horizontal band 120 can be erected. Thereby, the area | region of the light-shielding part shown to Fig.4 (a) can return to the original grid | lattice-like state, and can return to the state which raised all the vertical strips 110 and the horizontal strips 120. FIG.

  As described above, the blind 100 using the grid-like sheet material 101 according to the present embodiment tilts the vertical belt 110 and the horizontal belt 120 by tracing the grid-like sheet material 101 by hand, etc. It is possible to form the light shielding part 150 (or the non-venting part) in the part or the whole. Further, when changing from a state in which external light is blocked to a state in which light is transmitted (from a state in which ventilation is permitted to a state in which ventilation is blocked), it is only necessary to pull the end portion of the lattice sheet 101. Therefore, the blind 100 using the lattice-like sheet material 101 according to the present embodiment is superior in operability as compared with the conventional blind.

[Example 2]
FIG. 6 is a processed photograph of a bag using a lattice-shaped sheet material according to the embodiment of the present invention, and FIG. 7A is a development view of the lattice-shaped sheet material according to the embodiment of the present invention constituting the bag. FIG. 7B is an enlarged plan view of a part of the vertical band or horizontal band constituting the lattice-shaped sheet material. As shown in FIG. 6, the bag 200 includes a bundling portion 230 that forms a corner portion of the lattice-like sheet material 201 and is bound by a string-like body, and a hand portion for a user to hold the bag 200 by hand. 240. As shown in FIG. 7A, the bag 200 is configured by bending a single grid sheet material 201. The vertical belt 210 and the horizontal belt 220 are made of, for example, a polypropylene sheet having a thickness of 0.2 mm and a width W3 (FIG. 7B) cut to 10 mm. Further, as shown in FIG. 7B, slits 250 each having a slit interval p of 10 mm, a slit width s of 1.5 mm, and a slit length l of 5 mm are formed in the vertical band 210 and the horizontal band 220. Yes. Therefore, when the vertical belt 210 and the horizontal belt 220 having a thickness of 0.2 mm are inserted into the slit, a clearance of 1.3 mm is secured. Therefore, the direction of the vertical band 210 and the horizontal band 220 can be changed in the slit 250. Thereby, when a force is applied to the lattice-shaped sheet material 201, the crossing angle between the vertical belt 210 and the horizontal belt 220 changes, and the shape of the lattice-shaped sheet material 201 can be changed.

  As shown in FIG. 7A, in the lattice-like sheet material 201, the horizontal bands 220 (four at the top and the bottom) that constitute the two handed portions 240 are longer than the other horizontal bands 220. Therefore, the two handed portions 240 are formed so as to protrude from the lattice-shaped sheet material 201. When assembling the lattice-like sheet material 201 into the bag 200, first, the two bundling portions 230 constituting the corners of the lattice-like sheet material 201 are brought close to each other and bound together by a string-like body or the like. As described above, the vertical band 210 and the horizontal band 220 have a thickness smaller than the slit width s. Therefore, the vertical band 210 and the horizontal band 220 can change the crossing angle by the slit 250, and as a result, the lattice-like sheet material 201 can be freely bent. Thus, by bending the lattice-shaped sheet material 201, the crossing angle of the vertical band 210 and the horizontal band 220 changes continuously according to the curvature. Next, the two hand portions 240 are overlapped, and the horizontal band 220 of one hand portion 240 (lower right in the figure) is made into the slit 250 of the vertical band 210 in the other hand portion 240 (upper left in the figure). I will insert it. That is, the horizontal band 220 that constitutes the hand portion 240 is partially wrapped. Thereby, the two hand parts 240 can be integrated. Thus, the bag 200 shown in FIG. 6 is assembled.

  A desired pattern can be added to the bag 200 by appropriately selecting the color of the plate material constituting the vertical belt 210 and the horizontal belt 220 and the slit interval. Moreover, the bag 200 of a desired shape can be provided by selecting the lengths of the vertical belt 210 and the horizontal belt 220 as appropriate. In this way, it is possible to easily provide the back 200 having a pattern or shape desired by the user.

  The present invention is not limited to the above embodiment, and various modifications and improvements can be made. Although the vertical belt 110 and the horizontal belt 120 constituting the blind 100 described in the first embodiment have been described as being made of a polyethylene cloth body, they may be made of a cloth body using other materials. . For example, a synthetic fiber cloth such as nylon, polyester, or acrylic may be used. Moreover, you may use natural fiber cloths, such as cotton, hemp, and silk.

  Moreover, although the vertical band 210 and the horizontal band 220 which comprise the bag 200 demonstrated in the said Example 2 demonstrated that it was comprised from the sheet material made from a polypropylene, you may use another synthetic resin, for example, Polyethylene, polyvinyl chloride, polyethylene and the like can be used. Further, similar to the blind, the vertical belt 210 and the horizontal belt 220 may be made of cloth.

  In addition, a metal material can be adopted as a constituent material of the blind 100 and the back 200 described above. For example, various standard aluminum materials, stainless steel materials, steel materials, and the like. Even when the vertical band and the horizontal band are formed from such a metal material, the thickness can be determined so that the vertical band and the horizontal band can be continuously bent and the crossing angle of the vertical band and the horizontal band is continuously changed. In addition, the metal material has better light shielding properties than the above-described cloth body. For this reason, it is possible to provide a blind that is superior in light-shielding performance as compared to the blind configured from the cloth body described above.

  Moreover, the product of the color according to a user's hope can be provided by coating the vertical band and horizontal band which consist of metal materials. In addition, by setting different colors for each vertical band and horizontal band, or by setting different colors for each predetermined length of the vertical band and horizontal band, it is possible to provide a product with an ingenious color scheme it can.

  Further, not only the selection of the material and the color, but also the lattice spacing and the like can be appropriately changed according to the user's request.
