The apparatus described in Patent Document 1 includes two moire sheets on which a periodic figure by a combination of curves and straight lines is drawn, and a drive mechanism that fixes one moire sheet and moves the other moire sheet. Yes.

  The drive mechanism is composed of a cam, a crank, and the like. Both moire sheets are superimposed, and the moire pattern appears when the other moire sheet moves or swings by the drive mechanism. Further, the moire sheet may be transparent or semi-transparent as a whole, and it is said that the design effect can be enhanced by coloring the periodic figure.

Registered Utility Model No. 3064178

  In the conventional apparatus in which the moire pattern appears, only a periodic figure combining a curve and a straight line is drawn on the moire sheet. Therefore, the moiré pattern that appears in this moiré sheet is a geometric pattern that can be predicted, and it does not change as much as a kaleidoscope. It is not.

  Therefore, an object of the present invention is to provide a decorative device that attracts people's eyes and makes an interesting pattern appear, and a pattern changing method using the decorative device.

The decorative device according to the present invention is a decorative device including a plurality of sheets that are relatively displaced in a stacked state, and each of the plurality of sheets is opaque or translucent in which a large number of holes are formed. A sheet body is provided, and the plurality of holes are scattered at positions having regularity, and the holes of each sheet have a total of 5 points including 4 points at the corners of the rectangle and 1 point at the center of the rectangle. The basic unit repeats over the entire sheet with the length of the long side and the length of the short side of the rectangle, or a line that forms a diagonal line from the length of one side and the end of the side. It is characterized by being scattered at positions defined by repeating rectangles that can be defined by the angle of the entire surface of the sheet .

  According to this decorative tool, when a plurality of sheets are superposed by a large number of holes formed in the opaque or translucent sheet body being scattered at positions having regularity, A pattern appears when the holes of each sheet body overlap and communicate with each other. Then, when the plurality of stacked sheets are relatively displaced in the plane, the communicating hole portion is changed, and the appearing pattern is transformed as if it is completely changed.

  In addition, according to this accessory, the basic unit is composed of four holes at the corners of the rectangle and one hole at the center of the rectangle, for a total of five holes. A pattern can appear. In the present application, the rectangle includes not only a narrowly defined rectangle in which the lengths of adjacent sides are different, but also a square having the same length on all four sides.

  Further, the decorative device according to the present invention different from the above is a decorative device including a plurality of sheets that are relatively displaced in a stacked state, and each of the plurality of sheets has a plurality of holes formed therein. An opaque or translucent sheet body is provided, the numerous holes are scattered at positions having regularity, the diameter of the holes is 1.0 mm or more, and the entire area of the holes is defined as the sheet body.

  Embodiments of a decorative tool and a pattern changing method using the decorative tool according to the present invention will be described with reference to FIGS. As shown in FIG. 1 and FIG. 2, the decorative tool includes a plurality of sheets that are relatively displaced in a stacked state (in this embodiment, two sheets of a first sheet 10 and a second sheet 20). .)

  The first sheet 10 and the second sheet 20 are both opaque or translucent rectangular sheet bodies 11 and 21 with holes 12, 22 scattered at positions having the same regularity as shown in FIG. It is supposed to have formed. The holes 12 and 22 shown in FIG. 3 are both corners of a rectangle (the rectangle includes not only a narrowly-defined rectangle having different lengths of adjacent sides but also a square having the same length of all four sides). A total of 5 points including the 4 points and one point at the center of the rectangle are defined as basic units A to E.

  The center point is the intersection of the diagonal lines of the rectangle, in other words, the intersection of two straight lines connecting the centers of the vertical sides facing each other and the centers of the horizontal sides of the rectangle. . Any one of the basic units A to E is repeatedly arranged on the entire surface or part of the first sheet 10, and any one of the basic units A to E is further formed on the entire surface or part of the second sheet 20. It is scattered so as to be lined up repeatedly. Of course, the basic units A to E are not limited to the five types shown in FIG.

  As a specific example, the basic unit A shown in FIG. 3A has a rectangular long side of 4.34 mm and a short side of 2.5 mm, and the basic unit B shown in FIG. 3B has a rectangular long side. Is 3.27 mm, the short side is 2.1 mm, and the basic unit C shown in FIG. 3C has a rectangular long side of 3.9 mm and a short side of 2.1 mm, as shown in FIG. The basic unit D shown has a rectangular long side of 2.5 mm and a short side of 2.17 mm, and the basic unit E shown in FIG. 3E is a square with 2.5 mm on each side.

Then, on the entire surface or part of the sheet 10, 20 of the present invention, at least one of the plurality of basic units A-E, it is formed in the sheet over the entire surface with a regularity of a predetermined repetition. The number of basic units A to E formed in one sheet 10 and 20 may be one.

  In any of the basic units A to E, the holes 12 and 22 are circular, and the aperture Φ is 1.0 mm, 1.2 mm, 1.4 mm, 2. It is formed to 0 mm and 2.1 mm. Further, when the value obtained by dividing the entire area of the hole 12 by the area of the sheet main body 11 (including the area of the hole 12) is an aperture ratio k, the aperture Φ of the hole 12 in the basic unit A is 2. If it is 2 mm, the aperture ratio k is 0.700, and if the aperture Φ of the hole 12 is 1.0 mm, the aperture ratio k is 0.145. The same applies to the hole 22 and the sheet main body 21.

  Similarly, in the basic unit B, if the aperture Φ of the hole 12 is 1.5 mm, the aperture ratio k is 0.514. In the basic unit C, if the aperture Φ of the hole 12 is 1.7 mm, the aperture ratio k is 0.554. In the basic unit D, if the aperture Φ of the hole 12 is 1.4 mm, the aperture ratio k is 0.567. In the basic unit E, if the aperture Φ of the hole 12 is 1.4 mm, the aperture ratio k is 0.492. The same applies to the hole 22 and the sheet body 21 of any unit B, C, D, E.

  Here, a pattern appearing by the first sheet 10 and the second sheet 20 in which the above basic units are arranged in parallel will be described with reference to FIGS. Here, a case will be described in which the first sheet 10 is fixed and the second sheet 20 is displaced (operation such as rotational motion or linear reciprocating motion).

  The second sheet 20 moves manually or electrically. In the case of electric drive, a normal motor and a speed reducer may be combined, or a stepping motor may be employed.

  When both the first sheet 10 and the second sheet 20 are the basic unit A in which the holes 12 and 22 having a diameter of Φ2.2 mm are formed (A2.2), the first sheet 10 is fixed, and the second sheet When 20 is rotated from 0 ° to 360 °, a pattern as shown in FIG. 4 appears.

  As shown in FIG. 4A, the second sheet 20 is not rotated (0 °, 360 °) and 180 °, and the second sheet 20 is 60 ° as shown in FIG. When the second sheet 20 is rotated by 120 ° and 300 ° as shown in FIG. 4F, both the hole 12 of the first sheet 10 and the hole of the second sheet 20 are rotated. No. 22 is completely overlapped and no eye-catching pattern appears.

However, when the second sheet 20 is rotated 30 ° and 210 ° as shown in FIG. 4B, the second sheet 20 is rotated 150 ° and 330 ° as shown in FIG. 4H. When rotated, a dodecagon that appears to be circular appears at the position of the center of rotation of the second sheet 20, and a dodecagon of the same size that shares a certain side is the entire length of the sheet. It is formed one after another.

  Further, as shown in FIG. 4C, when the second sheet rotates 45 ° and 225 °, as shown in FIG. 4G, when the second sheet 20 rotates 135 ° and 315 °. When it rotates, it shows a pattern of hexagons of the same size spread without gaps. In this hexagonal pattern, a relatively large communication portion is gathered at the center, and six sides are formed by a set of relatively small communication portions.

  The first sheet 10 and the second sheet 20 are both the basic unit A in which the holes 12 and 22 having a diameter of Φ2.2 mm are formed (A2.2), the first sheet 10 is fixed, and the second sheet 20 5 °, 10 °, 20 °, 30 °, 40 °, 45 °, 50 °, 60 °, 70 °, 80 °, and 90 ° are shown in FIG. ) To (l) continuously change.

  Further, in the case where both the first sheet 10 and the second sheet 20 are formed in the basic unit A with the holes 12 and 22 having a diameter of Φ2.2 mm (A2.2), the first sheet 10 is fixed and the second sheet 20 is fixed. Appearing when the image is rotated by + 2 °, −2 °, + 5 °, −5 °, +10, −10 °, + 15 °, −15 °, + 20 °, and −20 ° are shown in FIG. It changes as shown in (k). When the absolute value of the rotation angle of the second sheet 20 is the same, the same pattern appears.

  In the case where both the first sheet 10 and the second sheet 20 are formed with the holes 12 and 22 having a diameter of 1.7 mm in the basic unit C (C1.7), the first sheet 10 is fixed and the second sheet 20 is fixed. Appearing when the angle is rotated from 0 ° (not rotated), 2 °, 5 °, 10 ° to 90 ° in increments of 10 °, changes as shown in FIGS. To do. The pattern appearing by the first sheet 10 and the second sheet 20 of C1.7 is different from the pattern appearing by the first sheet 10 and the second sheet 20 of A2.2 shown in FIG.

  In the case where the first sheet 10 and the second sheet 20 are both formed with the holes 12 and 22 having a diameter of 1.4 mm in the basic unit D (D1.4), the first sheet 10 is fixed and the second sheet 20 is fixed. The patterns that appear when the angle is rotated from 0 ° (not rotated) to 110 ° change as shown in FIGS. 8A to 8S, and the angle ranges from −10 ° to + 10 °. The patterns that appear when rotated at the positions change as shown in FIGS. In the first sheet 10 and the second sheet 20 of D1.4, a striped pattern appears.

  In the case where both the first sheet 10 and the second sheet 20 are formed in the basic unit E with the holes 12 and 22 having a diameter Φ1.5 mm (E1.5), the first sheet 10 is fixed, and the second sheet 20 is − The patterns that appear when rotated at an angle in the range of 20 ° to + 20 ° change as shown in FIGS. 10 (a) to 10 (k). The pattern of the D1.4 sheets 10 and 20 (FIG. 9) and the pattern of the E1.5 sheets 10 and 20 (FIG. 10) are slightly different in the range of about ± 10 °, but show similar patterns. Yes.

  The first sheet 10 is a basic unit A in which a hole 12 having a diameter of Φ2.2 mm is formed (A2.2), and the second sheet 20 is formed in the basic unit A having a hole 22 having a diameter of Φ1.4 mm. (A1.4), the pattern that appears when the first sheet 10 is fixed and the second sheet 20 is rotated at an angle in the range of −20 ° to + 20 ° is shown in FIGS. k).

  The first sheet 10 is a basic unit B in which a hole 12 having a diameter of Φ1.5 mm is formed (B1.5), and the second sheet 20 is formed in the basic unit E having a hole 22 having a diameter of Φ1.4 mm. The pattern that appears when the first sheet 10 is fixed and the second sheet 20 is rotated from 0 ° to 90 ° in the case (E1.5) is as shown in FIGS. Change.

  In the case where the first sheet 10 and the second sheet 20 are both formed with the holes 12 and 22 having a diameter of 1.4 mm in the basic unit D (D1.4), the first sheet 10 is fixed and the second sheet 20 is fixed. Is inclined by 2 ° with respect to the first sheet 10 (stopped after rotation), and the pattern that appears when the base unit D moves from -10 mm to +10 mm (straight forward movement) in the long side direction (left-right direction in the drawing) As shown in FIGS. 13A to 13R, hexagonal comparatively bright portions appear so as to be stacked in a close-packed manner and move without transformation.

  That is, this pattern does not appear to move in the long side direction of the basic unit D, but appears to move only in the short side direction (vertical direction in the drawing) of the basic unit D. In the example of FIG. 13, when the second sheet moves to the right (plus display), the pattern moves downward in proportion.

  The first sheet 10 is a basic unit A in which holes 12 and 22 having a diameter of Φ2.2 mm are formed (A2.2), and the second sheet 20 is formed in the basic unit A with a hole 12 having a diameter of Φ1.4 mm. , 22 (A1.4), the first sheet 10 is fixed, the second sheet 20 is inclined by 2 ° with respect to the first sheet 10 (stopped after rotation), and the short side direction ( The pattern that appears when moving from +1 mm to -1 mm in the vertical direction in the drawing changes as shown in FIGS. In the example of FIG. 14, when the second sheet is moved upward (plus display), the pattern moves in proportion to the right.

  This pattern appears so that the relatively bright portions of the hexagonal shape are stacked in a close-packed manner, and appears to move (straightly move) in the long side direction (left-right direction in the drawing) of the basic unit A. That is, the pattern that appears when the second sheet 20 is tilted moves in a direction orthogonal to the rectilinear direction of the second sheet 20 without changing at least with the naked eye. The moving speed of the pattern is proportional to and interlocked with the moving speed of the second sheet. When the moving direction of the second sheet 20 is reversed, the moving direction of the pattern is also reversed.

  Furthermore, if the relative angle between the first sheet 10 and the second sheet 20 changes, the appearing geometric pattern will be completely changed.

  As described above, the first sheet 10 and the second sheet 20 that are overlapped with each other are relatively displaced, so that the appearing pattern changes like a kaleidoscope. This change is continuous, and at the same time, the speed of change increases or decreases or stops before returning to the original pattern. Therefore, this pattern attracts the eyes of passers-by and the shoppers in the store, for example, who are watching the show window facing the aisle. Attention is paid to this, and the light in the store overflows through the communicating part of the pattern, and the store enters the field of view. And they are guided into the store or motivated to purchase.

  In addition, this invention can be variously changed without being limited to the said embodiment. That is, it goes without saying that the size of the diameter Φ of the basic units A to E and the holes 12 and 22 is not limited to the above specific example.

  Moreover, the hole parts 12 and 22 are not limited to a circular shape, and may have an elliptical shape, a star shape, a polygonal shape, a heart shape, or the like. However, the irregularly shaped holes 12 and 22 are provided so that the area-converted center of gravity is formed at the same position as the area-converted center of gravity of the circular holes 12 and 22. The diameter Φ of the irregularly shaped holes 12 and 22 is a diameter of a circle assuming an area equivalent to the opening area of the single hole 12 or 22. If these hole portions 12 and 22 interfere (overlap) with the adjacent hole portions 12 and 22, the mechanical strength of the sheet is remarkably lowered, which is not preferable.

  The aperture Φ of the holes 12 and 22 is preferably 1 mm or more. This is because if it is less than 1 mm, it becomes difficult to obtain the required aperture ratio k. The aperture ratio k is preferably 0.1 or more and 0.75 or less. If the aperture ratio k is less than 0.1, the pattern becomes dark and difficult to see. When the aperture ratio k is larger than 0.75, the mechanical strength of the sheets 10 and 20 is weakened, and not only the durability becomes poor, but the pattern becomes too bright, so that the transformation of the pattern is difficult to be sharpened. . In addition, when the opening ratio k of one sheet 10 (20) is close to 0.1, the opening ratio k of the other sheet 20 (10) exceeds 0.4, thereby making it easy to visually recognize the pattern. be able to.

  Further, if the interval between the adjacent holes 12 and 22 is shortened so that the necessary aperture ratio k can be obtained when the diameter Φ of the holes 12 and 22 is less than 1 mm, the pattern unique to the geometric pattern is obtained. This is not preferable because it is not easy to see because it is small, and it is not possible to make an eye-catching pattern appear, but also because the number of holes 12 and 22 increases, the time and cost for manufacturing the sheet increase. .

  On the other hand, the upper limit of the diameter Φ of the holes 12 and 22 differs depending on whether the use place of the ornament is a show window or a courtyard of a shopping mall, and is appropriately set. However, it goes without saying that the hole portions 12 and 22 are formed so as not to interfere with each other in any application.

  In the above embodiment, the first sheet 10 and the second sheet 20 having the same basic unit are overlapped, and the first sheet 10 of the different basic unit is overlapped with the second sheet 20. did. When the diameters Φ of the hole portions 12 and 22 of the first sheet 10 and the hole portions 12 and 22 of the second sheet 20 are different, the aperture ratio obtained by dividing the large aperture Φ by the small aperture Φ is 2 The following is preferable. This is because when the aperture ratio exceeds 2, the amount of light passing through the holes 12 and 22 having a large aperture becomes dominant, and the pattern that appears due to the relative movement of the two sheets becomes monotonous.

  Further, in the decorative device according to the present invention, in the decorative device in which the basic units of the first sheet 10 and the second sheet 20 are the same and the hole diameter is the same, either one of the sheets 10 (or 20) without changing the hole diameter. The repetition pitch of the holes 12 (or 22) may be different. In such a decorative tool, when a value obtained by dividing a large pitch by a small pitch is a “repetitive dimension ratio”, it is preferable that the repetitive dimension ratio is 1.3 or less. This is because if the ratio of the repeated dimensions is larger than 1.3, the geometric pattern is difficult to appear or even if it appears.

Moreover, in the said embodiment, each of the basic units A-E is made to the whole surface of the 1st sheet | seat 10 and the 2nd sheet | seat 20, and the length of each long side and the length of a short side (in the case of a square, the length of one side). Therefore, it was scattered so as to fill the entire surface at a position defined by repeating the entire surface of the sheet . However, the basic units A to E may be provided in a part of the sheet main bodies 11 and 21.

  In the above embodiment, the sheets 10 and 20 all have the same basic unit. However, the 1st sheet | seat 10 and the 2nd sheet | seat 20 are good also as what combined the basic unit A with the basic unit A in a certain part, and the basic unit B in another part. Moreover, in the said embodiment, all the hole parts 12 and 22 of each unit AE were formed in the same aperture diameter (PHI). However, the holes 12 and 22 may be formed such that a part of the sheet has a different diameter Φ, or a combination of a circular shape and an irregular shape.

  Moreover, the decoration tool of the said embodiment fixed the 1st sheet | seat 10 and moved the 2nd sheet | seat 20. As shown in FIG. However, the decoration tool may move both the first sheet 10 and the second sheet 20. Further, the first sheet 10 or the second sheet 20 may be rotated after going straight.

  Further, the decoration tool may include three or more sheets 10 and 20. In the present invention, the two sheets 10 and 20 exhibit a sufficient function, but the number of sheets exceeding three is allowed as long as the function of the present invention is not impaired. For example, the third sheet may be a semitransparent sheet that is colored, and holes may be formed at positions where the sheet has regularity. In this case, the change of the appearing pattern can be easily controlled by fixing one sheet instead of moving all the sheets. The pitch and the diameter of the hole portions of the fixed sheet may be different from the pitch and the diameter of the hole portions of the relatively moving sheet.

  In the basic units A to E of the above embodiment, the holes 12 and 22 are formed at a total of five points including four points at the corners of the rectangle defining the length of two sides and one point at the center of the rectangle. However, the basic units A to E may have a total of five points, that is, a vertex of a rectangle defined by a length of one side and an angle with respect to the side as a reference and one point at the center.

  Further, the basic units A to E of the above embodiment are defined by the lengths of two sides adjacent to each other at a right angle of a quadrangle that defines the length of the two sides. However, the basic unit may be defined by different one side and an angle (for example, 30 ° or 45 °) with respect to the one side. By forming the holes 12 and 22 at a constant angle, the pattern that appears when the sheets 10 and 20 are rotated is the same at any position.

  In the basic units A to E of the above embodiment, the holes 12 and 22 are formed at a total of five points including four points at the corners of the rectangle and one point at the center of the rectangle. However, the basic units A to E may form the holes 12 and 22 at the four corners of the rectangle without forming the holes 12 and 22 at the center of the rectangle.

  In addition, when the holes 12 and 22 are formed based on the length of the sides of the rectangle, when the sheets 10 and 20 are rotated, the holes 12 and 22 that are away from the center are shifted and overlapped. However, since the sheets 10 and 20 are rotating, it is difficult to notice that the holes 12 and 22 are displaced from each other, and the pattern is drastically changed.

  Moreover, in the said embodiment, any one of the 1st sheet | seat 10 and the 2nd sheet | seat 20 may be formed with a magnetic body, and the other may be formed with a magnet. By doing so, the first sheet 10 and the second sheet 20 are magnetically attracted, and the moved second sheet 20 can be reliably temporarily stopped. However, the first sheet 10 and the second sheet 20 may be formed of non-magnetically attached metal, plastic, paper, or the like.

  Since the decorative tool of the present invention also has a function as a light control tool, it can be used by being mounted on a window. The decorative tool of the present invention can be used for a projector such as a lamp shade or an event hall by utilizing the fact that the shape of the part through which light is transmitted changes drastically. The ornaments of the present invention used for these can make the sheets 10 and 20 blackish or colorfully colored, so that they are more interesting.
