JP3677182B2 - Origami hand box and other handicraft paper folding line size setting and production aids - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention determines the size in millimeters when continuously folding paper of the same size on paper such as paper or foil, and continuously holds the determined size, such as an origami hand box, a hobby envelope, a chopstick case, etc. It is an instrument that assists in the production of handicrafts and daily necessities.
[0002]
[Prior art]
The technology to fold origami boxes from a single sheet of paper without any wrinkles is a traditional Japanese handicraft, but the size and height of the work, the selection of the paper size associated with it, and the continuous production of the same work and in millimeters It is difficult to fold the outer and inner boxes due to the difference.
[0003]
[Problems to be solved by the invention]
Accurate and easy fold line size setting in millimeters. Assists in sizing by sound and feel. The set size can withstand continuous use without going crazy. A tight crease. Insert easily without damaging the corners of the paper. Production of outer and inner boxes from the same size paper with the same size settings. Simple, lightweight and compact instrument. And so on.

[Means for solving]
When viewing a rectangular plate vertically, the left long side has an L-shaped convex surface on the upper corner, an inverted L-shaped convex surface on the lower corner, a U-shaped cut at the center of the left long side, and above and below the U-shaped cut. Each wavy concave and convex groove band is formed by processing and molding the right long side cross section on the reverse slope side, the right long side lower corner on the paper insertion part, and the short side with the same size as the base and the long side. Cut the right long side cross-section of the rectangular plate 1 mm shorter than the short side of the base on the slope side, take the upper corner of the right long side, and insert a U-shaped cut at the same location as the base in the center of the left long side. , Respectively, and the upper and lower sides of the U-shaped notch with a scale in millimeters and a number in centimeters as the top lid, the same size as the base and the long side, inside the L-shaped inverted L-shaped convex surface A V-shaped groove is formed on the right long side cross section of the T-shaped plate molded so that it can be fitted tightly, and a protrusion line is formed on the portion engaging with the wavy uneven groove band. And the knob that moves while pointing at the scale with double arrows in the U-shaped cutout of the upper lid, and each processed and molded as a T-shaped moving plate, this is fitted into the base and the upper lid is covered, the base and the upper lid The problem was solved by a device that was bonded with an L-shaped inverted L-shaped convex surface.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the invention will be described with reference to the drawings.
The size is determined by adjusting the arrow 4 to the scale 5 with the knob 3 in FIG. 1, and the paper 10 is accurately inserted from the paper insertion portion 11 along the V-shaped groove 9, and bent at the inclined side 12 to form a fold line.
[0006]
10 and 12, the 1 mm wide protrusion line 8 attached to the lower surface of the T-shaped moving plate 6 is engaged with the wavy uneven groove band 7 of FIGS. 3, 7, and 8, and movement in millimeters is sensed and touched. At the same time, it also serves as a stopper.
[0007]
When making an origami hand box, fold it according to the reference fold diagram of FIG. 13 (how to fold the hand box). First, as shown in (a), fold lines are attached to ii and ii '(short sides if rectangular) and folded inside, and fold lines are added to bis and b' (long sides if rectangular) in (b). Fold it twice, fold lines c and c 'in (c), fold inward, return, fold each corner inward, and fold back. Next, return the part folded twice as shown in (d) until it is folded once, open each corner, fold up according to the fold line as shown in (e), and stand upright at a right angle as shown in (f). Glue and fold down, and the outer box is completed in the same way on the other side. When the instrument is turned upside down and folded in the same way, a middle box with a difference of about 1 mm is formed, and an origami hand box is completed as shown in (g).
[0008]
【The invention's effect】
Since this invention is comprised as mentioned above, there exists an effect described below.
When the T-shaped moving plate 6 according to claim 1 moves in a balanced manner, the protruding line and the wavy uneven groove band convey an accurate indentation sound and feel to assist the resizing in millimeters by the eye, and at the same time, the V-shaped groove By eliminating the misalignment of the paper and making the top cover base width 1mm difference, the inside box can be created simply by turning over the main body, the paper insertion part facilitates the paper insertion, the slanted side is given a crease, and a wide range including hand boxes Provided convenience for daily necessities and handicraft production.
