[0006]
And the decorative umbrella of claim 2 is
A decorative umbrella assembled by folding a plurality of papers of the same pattern, wherein the center of the same position is set on all the papers, and a plurality of straight lines passing through the centers are equally divided around the entire circumference. For each sheet, the position information of the radial straight lines with different angles set by dividing equally is transferred for each sheet one by one, and each sheet is folded in accordance with the straight line information transferred to each sheet. The plurality of substantially triangular mountain fold pieces created so that the center is one vertex and the mountain fold side is the bottom side, and the short side of the substantially triangular shape is parallel to the axis of the decorative umbrella In this way, it is configured to be radially arranged around the axis of the decorative umbrella.
[0007]
[Action]
According to the method for assembling the decorative umbrella of the present invention,
Set a plurality of straight lines that pass through the center of the paper in a radial pattern with an equally divided angle
For each sheet, the position information of the radial straight lines having different angles set by the equal division is transferred one by one. The pattern in the vicinity of this straight line is the part that appears on the surface of the decorative umbrella after it is assembled.
When each sheet is folded in accordance with the position information of the straight lines transferred to the respective sheets, a pattern in the vicinity of the mountain fold side appears on the surface of the decorative umbrella after assembling. At this time, it is difficult to see if a straight line is drawn on the mountain fold side. It is better to transfer it so that it doesn't stand out.
In addition, the position information of radial straight lines having different angles is transferred and bent on each sheet. The pattern that appears on the mountain fold side of each mountain fold piece is different.
In particular, when comparing the mountain fold pieces created by folding the paper to which the position information of the adjacent straight lines is folded, the patterns near the mountain fold sides are adjacent to each other. The continuous pattern is a partial pattern of the original pattern on the paper.
Therefore, when the mountain fold pieces created in this way are aligned in the same order as the original straight line transferred, the pattern appearing on the mountain fold side becomes continuous as a whole. It is a pattern around the center of the original pattern.
In this way, when the decorative umbrella is completed by aligning around the axis, the original pattern of the paper appears on the surface of the decorative umbrella.
In addition, although it assembled after producing the substantially triangular mountain fold piece of the shape of FIG. 10, it is also possible to produce and assemble the triangular mountain fold piece as shown in FIG.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Below, the assembly method of the decorative umbrella concerning this invention is demonstrated in detail based on drawing which showed the embodiment.
[0009]
FIG. 1 is a plan view of a sheet of paper P, and for example, a sunflower pattern as illustrated is printed on it.
According to the method for assembling the decorative umbrella of the present invention, it is possible to assemble the decorative umbrella U as shown in FIG. A sunflower pattern similar to that of the paper P in FIG. 1 appears on the surface of the decorative umbrella U in FIG.
[0010]
Hereinafter, the method of the present invention for assembling the decorative umbrella U of FIG. 2 from the paper P of FIG. 1 will be described step by step.
First, as shown in FIG. 3, the center C is set at a desired position of one sheet of paper P0 (referred to as pattern paper P0). Since this center is the center of the pattern that appears on the decorative umbrella, it is preferably set at the center position of the paper.
Next, radial straight lines L1 to L48 passing through the center are drawn. The angle formed by these adjacent straight lines is 3.75 ° (= 180 ° / 48). The number of straight lines is not limited to 48.
[0011]
Next, as shown in FIG. 4, the position information of one straight line of the pattern paper P0, for example, L1, is transferred to another paper P1. At this time, a mark corresponding to the position of the straight line L1 may be attached to the peripheral portion of the paper P1 without actually drawing the entire straight line L1.
Then, as shown in FIG. 5, the position information of another straight line, for example L2, is transferred to another sheet P2.
In this way, the position information of the different straight lines L1 to L48 is transferred one by one to 48 sheets of paper.
In order to efficiently perform the above transfer operation, a plurality of sheets and the pattern P0 are overlapped, and a position is obtained by providing a needle hole by inserting a needle into the center and a point obtained by dividing 360 ° into 96 equal parts. Information may be transferred. In this way, it is only necessary to fold each sheet along a straight line connecting the needle holes, so that the transfer operation is facilitated.
[0012]
Next, as shown in FIG. 6, along the straight line position information transferred to each sheet, the image is folded in a mountain so that the pattern comes to the front. FIG. 6 is an explanatory diagram when the paper P10 is folded in a mountain along the position of the straight line L10.
Then, the mold plate 3 having the shape as shown in FIG. 13 is overlapped, and sewing needles or pins are inserted into the positioning holes H1, H2, H3, and H4 provided in the mold plate 3 and shown in FIG. In this way, the positioning marks M1, M2, M3, and M4 are formed, and the cut line S is formed.
As shown in FIG. 7, two molds can be formed on both sides of the center of one sheet.
If the two molds obtained in this way are given their respective numbers, the order will be easier to understand when assembled later. For example, in the case of FIG. 7, since the mountain is folded along the position of the straight line L10, the numbers are “10” and “58” including 48.
[0013]
Next, as shown in FIG. 8, the positioning marks M1, M2, M3, M4 and the cut line S formed on the mountain fold cut piece 12 are used as marks, and FIG. 8 and FIG. Make a break K as shown. As described above, two mountain-folded cut pieces 12 and 12 are obtained from one sheet.
As shown in FIG. 9A, one cut K1 is provided in a straight line connecting the positioning mark M2 to a corner near the positioning mark M3,
Another cut K2 is provided in a straight line from the positioning mark M2 through the positioning mark M4.
Next, as shown in FIG. 8 and FIG. 9A, folding is performed according to the folding lines R <b> 1 and R <b> 2 formed in each mountain fold cut piece 12. (See FIGS. 9A and 9B.)
Further, folding is performed according to the center folding line R4. (See (b) and (c) of FIG. 9.
)
Furthermore, it folds according to the fold line R3, and as shown to (d) of FIG. 3, the substantially triangular shaped fold piece 13 is obtained.
Ninety-six such folded pieces 13 are prepared, and the threads 41 and 42 are respectively passed through the threading holes M1 and M3 formed in the folded pieces 13, and the threads 41 and 42 are tightened to form an umbrella shape. To arrange. (See FIGS. 9, 10, and 11.)
And an adhesive etc. are apply | coated to the inner surface of a center hole, and the cylinder 5 is inserted and fixed.
[0014]
After the shape is arranged in an umbrella shape in this way, as shown in FIG. 12, the toothpick 6 is inserted one by one into the gap formed at the end of each folding piece 13 corresponding to the peripheral portion of the umbrella shape. . Then, at the rear end of each toothpick 6, a thread 71 is wound around a portion located at the umbrella-shaped peripheral edge. At this time, it is good to stop with a small amount of adhesive.
Further, another thread 72 is wound around the outside of the thread 71, that is, around the narrow part at the end of each toothpick 6.
[0015]
As described above, when the shaft member 8 such as a pencil is passed through the cylinder 5, the decorative umbrella 1 as shown in FIG. 12 (same as the decorative umbrella U in FIG. 2) is completed.
[0016]
3 to 12, the pattern is omitted, but actually, the pattern of the original paper appears on the surface as shown in FIG. 2.
The reason why the original pattern appears on the surface of the finished decorative umbrella is as follows.
[0017]
Since each mountain fold cut piece 12 is cut off at a position slightly shifted from the original paper, the pattern near the mountain fold side of each mountain fold cut piece 12 is in the vicinity of a different straight line of the original paper. It has become a pattern.
That is, the pattern in the vicinity of the mountain fold side of the mountain fold cut piece 12 created from the paper on which the position information of the adjacent straight lines is transferred is a pattern adjacent to each other. The pattern is a partial pattern of the original pattern on the paper.
Therefore, when the mountain fold cut pieces 12 created in this manner are aligned in the same order as the original transferred straight lines, the patterns appearing on the mountain fold sides of each mountain fold cut piece 12 are generally continuous, The continuous pattern is a pattern around the center of the original pattern on the paper.
In this way, the original pattern of the paper appears on the surface of the completed decorative umbrella by aligning around the axis.
In implementing the present invention, a large number of pamphlets with the same pattern are required, so that it is possible to effectively use a large number of pamphlets that are no longer necessary at business establishments.
[0018]
【The invention's effect】
According to the method for assembling a decorative umbrella according to the present invention, when assembling a decorative umbrella by folding a plurality of papers having the same pattern, a center of the same position is set for all the papers, and a plurality of papers passing through the center are set. A straight line is set radially at an angle that divides the entire circumference equally, and for each sheet, the position information of the radial straight line with a different angle set by dividing equally is transferred one by one. A mountain fold piece is created by folding the mountain according to the position information of the straight line transferred to, and the mountain fold piece is processed to have the center as one vertex and a substantially triangular shape with the mountain fold side as the bottom. A plurality of mountain fold fragments created in this way are aligned radially around the axis of the decorative umbrella so that the short side of the substantially triangular shape is parallel to the axis of the decorative umbrella. Let the mountain fold edge form the surface of the decorative umbrella Since assembled manner, it is possible to reveal the original picture on the surface of the decorative umbrella.
Therefore, if a flower-pattern paper is used, a flower-pattern decorative umbrella is obtained, and if an animal-pattern paper is used, an animal-pattern decorative umbrella is obtained. It can be done.
