Abstract

PROBLEM TO BE SOLVED: To achieve the accurate and easy setting and continuous use of a fold line size by simple constitution, by fitting a T-shaped moving plate having a projected line applied to the undersurface thereof in the gap between an upper lid and a base plate to which a wavy uneven groove strip is applied, and matching the arrow provided to the knob of the T-shaped moving plate with the graduations of the upper lid to determine a size. SOLUTION: An upper lid 1 wherein a horizontal U-shaped slit is formed to the central part of the left side of a square or rectangular plate, the right side thereof is set to a slope side 12, and a paper insertion part 11 is provided to the upper corner of the plate; and a base plate 2 having a shape almost same to that of the upper lid and having a paper insertion part provided to the lower corner to the right side thereof and having a corrugated uneven groove strip 7 and a projected surface 13 respectively formed to the upper and lower parts thereof; are bonded through the projected surface 13. A T-shaped moving plate 6 with a thickness less than 5 mm having a projected line 8 provided to the undersurface thereof and having a V-shaped groove 9 provided to the cross section of the long side thereof and knob 3 provided to the handle part of the T-shaped left side thereof is fitted in the gap between the upper lid and the base plate. The arrow 4 of the knob 3 is matched with the graduations 5 of the upper lid 1 to determine a size and paper 10 is accurately inserted from the paper insertion part 11 along the V-shaped groove and bent to apply a fold line.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for determining the size in millimeters when continuously fold lines of the same size on paper, such as paper or foil, and holding the determined size continuously. It is an instrument that assists in the production of handicrafts and daily necessities such as envelopes and chopstick cases.

[0002]

2. Description of the Related Art The technique of folding origami hand boxes from a piece of paper without inserting scissors is a traditional handicraft in Japan, but the size of the work, the height of the work, the selection of the paper size accordingly, and the continuation of the same work It is a difficult task to fold the outer and middle boxes depending on the production and millimeter difference.

[0003]

An accurate and easy setting of a folding line size. Assists in size setting by eye with sound and feel.
Withstands continuous use without changing the set size. Easy resizing in millimeters. Crisp creasing.
Insert the paper easily without damaging the corners. Simple, lightweight and compact equipment. And so on.

[0004]

The selection of the shape and thickness of the T-shaped moving plate. Engraving device for protruding line and wavy uneven groove band in millimeter units, V-shaped groove, slope side, paper insertion part.

[0005]

Embodiments of the present invention will be described with reference to the drawings. The size is determined by aligning the arrow 4 with the scale 5 with the knob 3 of FIG.
And then insert it exactly along the V-shaped groove and bend it to make a fold line.

A 1 mm wide projection line 8 attached to the lower surface of the T-shaped moving plate 6 shown in FIGS. 10 and 12 is engaged with the corrugated uneven groove band 7 shown in FIGS. 3, 7 and 8 to serve as a stopper. At the same time, it is a device that confirms movement in millimeters with sound and feel,
The reason why the line width and groove width are set to 1 mm is that, when using paper having a thickness that can be folded manually, the average dimensional difference between the outer box and the inner box is about 1 mm.
mm.

When making an origami hand box, the fold is made according to the reference fold diagram (how to fold the hand box) in FIG. First, as shown in (a), a fold line is attached to a and a ′ (short side in the case of a rectangle) and folded inward, and a fold line is attached to b and b ′ (a long side in the case of a rectangle) in (b), respectively. Fold it twice, fold it inward with a fold line at (c) and (c), return it, fold each corner inward,
Return with a fold line. Next, return to the fold once the place folded twice as shown in (d), open each corner, fold up according to the fold line as shown in (e), stand up at a right angle as shown in (f), Glue and fold, and the outer box is completed in the same way on the other side. When the device is turned upside down and folded in the same way to make the same product, a middle box with a difference of about 1 mm is formed, and as shown in (g), an origami hand box is completed.

[0009]

Since the present invention is configured as described above, the following effects can be obtained.

According to the first aspect, when the T-shaped movable plate 6 moves in equilibrium, the protruding line and the wavy concave and convex groove band transmit an accurate ticking sound and feel to assist the eye to change the size in millimeter units, The groove eliminates misalignment of the paper, the upper lid base width is about 1 mm difference measures, the inner box can be made just by turning over the main body, the paper insertion part facilitates paper insertion, the slope side has a sharp crease, the hand box First of all, it provided convenience for a wide range of daily necessities and handicraft production.
