Description

The present invention relates to an auxiliary tool for folding origami.

With the aging society, nursing care facilities, nursing homes, day service facilities, etc. for the elderly and disabled are increasing. These facilities use various exercises and cultural activities for rehabilitation and recreation, but the origami classroom is most effective for revitalizing the hands and brain and maintaining the remaining functions. This is one of the most widely used activities. In addition, origami has been widely adopted as a teaching material for Japanese culture in the world that promotes brain development and develops concentration and creativity in early childhood education such as kindergartens and elementary schools.

The classic origami is probably a “paper crane”. This is because if you can fold a “folding crane” that requires a basic technique from origami to a very advanced technique, you will be able to fold many other types of origami works.
Among the elderly, those who are good at origami, those who are not, various, but those who have hemiplegia due to stroke sequelae etc., those who have difficulty in fine fingertip movement due to rheumatism etc. can not be folded neatly, so origami Although hesitated to participate in the classroom, even if such people use only one hand or both handicapped hands, (1) origami folded with the corners of the origami aligned (2) The bag-shaped part folded in a triangle is folded and crushed. (3) As the fold progresses, the width of the tail and neck of the crane is narrow and even if it becomes a sharp acute angle, it can be folded straight. In order to be able to fold and enjoy origami neatly, there is a need for auxiliary and self-help tools that can be applied not only to cranes but also to many other types of origami works.

Therefore, various techniques for providing a folding line to origami have been proposed as conventional techniques for origami assisting tools. (See Patent Document 1). However, if the fold line is only attached, it can be folded with only one hand as the fold line is. It was difficult to cause deformation.)

In addition, a technique for folding paper neatly has been proposed. (See Patent Document 2). However, this technology was a technology to fold A4 paper.

In order to achieve the above object, the fourth problem-solving means has an angle of 90 degrees, 45 degrees, 22.5 degrees, and 11.25 degrees with respect to the folding plate based on a predetermined position of the edge. it is obtained by the origami aid according to claim 1 or claim 3, wherein the displaying lines.

In order to achieve the above object, a fifth problem solving means is characterized in that the end of the edge of the folding plate is slightly warped to form an origami insertion slot between the base and the folding plate. The origami assisting tool according to claim 2, 3 or claim 4 .

6 For solving the problem means to achieve the above object of claim 1, 2, 3, 4 or claim 5 Origami aid, wherein the attached elastic anti-slip material on the back surface of the substrate It is what.

The eighth problem-solving means is characterized in that an elastic anti-slip material is attached to the back surface of the substrate in order to achieve the above object. The origami assisting tool described in 7 is used.

The effects of the above solution are as follows.

When folding a paper crane using the origami auxiliary tool of the present invention, the square origami is first folded in half to make an isosceles triangle,
The first method is to insert between the folding plate and the board from the upper corner of the origami and look at the upper corner of the folding plate, align the lower corner in front, and then firmly hold it with your thumb and index finger. Hold the corner up against the board with the middle finger so that the origami does not move, and the rounded part on the side of the thumb on the side of the thumb is made of a thin and durable plastic sheet. By pulling up to a straight edge, which is the lower edge, and sliding it several times while pressing along the edge, it is possible to fold it into an isosceles triangle with a mountain fold even with one hand.

If the edge is too thick, slide the folded part down to the edge and slide it on the board while pressing the folded part again with your finger to remove the gap for the edge of the folded part. The paper and the paper are in close contact and cannot be folded. (If the edge is too thick, it may be a knife-like edge that thins toward the side edge and does not cut the paper.)
If an anti-slip material made of foam rubber sheet or the like is attached to the back side of the board, the board placed on the desk will not slip even if you slide while pressing with your finger. Both of them can be folded with just one hand.

The second method is to insert the origami under the folding plate from the upper corner of the origami, align the left and right corners of the origami with the straight edge of the lower edge of the folding plate, and remove the origami from the top of the folding plate. While pressing down, fold up the front origami with your thumb and press it against the folding board as it is, and replace the middle finger or ring finger to hold the origami so that it does not move, and follow the edge of the folding board on the side of your thumb. If you slid several times in the horizontal direction while holding the fold of the folded origami, you can fold it into an isosceles triangle with the corners of three places even with one hand.

As a third method, one side of the square origami held with one hand is pressed against the paper holding frame while sliding on the substrate surface, and the other side is pressed against the paper holding frame while lifting the other side. You can fold it into an isosceles triangle with just one hand even if you slide it while holding the middle corner or ring finger with the upper corner and then sliding while pressing the rounded part of the front with the side of your thumb. It becomes possible.

Next, when the edge of the folding plate is inserted from the insertion portion where the edge of the folding plate is slightly warped from the mountain fold portion of the isosceles triangle formed by any of the methods described above, the edge of the folding plate is inserted into the other hand. It can be inserted with one hand without lifting it.
Then, with the top of the isosceles triangle origami above the folding plate at the 45 ° vertex, with the top of the front overlapped, pull it up and fold it up with the edge of the folding plate. It is possible to fold two (back-to-back) isosceles triangles of half size.

Then, when the opening of one bag of these two isosceles triangles is inserted into a taper stick standing on the paper holding frame and pulled to the front, this taper stick plays the role of the finger of the other hand, The bag can be opened only by use. (Because the weight of the board etc. is heavier than the force required to open the bag. Also, since the elastic anti-slip material is stuck on the back of the board, the board does not move even if the inserted paper is pulled sideways. Then, if you put the open part in the square on the paper pad and slide it while holding it with your index finger, you can crush and fold it into two squares.

Then, insert this from the insertion opening at the edge of the edge, align the corner to be folded next with the starting point on the edge of the angle line, and from the transparent sheet to the 22.5 degree straight line written on the folding plate Match the diagonal fold lines that can be seen through, hold down the origami laid down with the index finger, ring finger, and little finger firmly from the top of the folding plate, and slide along the edge while pressing with the belly of the thumb Even with one hand, it can be folded exactly 22.5 degrees.
Similarly, the remaining three locations can be folded at 22.5 degrees.

Fold it forward and fold the 22.5 degree part to 11.25 degrees in half, and it will be the stage before folding the neck and tail, which is the point of appearance of the folded paper crane, but the most clumsy or one-handed person is the most The technique of folding a narrow part, which is not good, straight and sharp, can be folded relatively easily when the origami aid of the present invention is used.

That is, align the center line of the origami inserted under the 11.25-degree line of the folding plate, hold it from the top of the folding plate on the nail side of the middle finger or ring finger, and hold the lower origami on the belly of the thumb When it is lifted and slid several times while holding it with the flank of the thumb along the folding plate, it can be folded at 11.25 degrees. (When narrow paper is folded vertically, it is difficult to fold it because it is difficult to pinch the narrow part with your fingertips. An example.)

And a paper crane can be completed using the origami auxiliary tool of this invention here and there.
And if you stand a thick origami textbook on a commercial reading stand, the turned page will not close, and if you look at this and use the origami aid of the present invention even with one hand, many types of origami It will be possible to complete it.
Using the origami auxiliary tool of the present invention that can be folded with one hand, it is possible for elderly people, infants, and somewhat clumsy people to complete their origami works more neatly than before with both hands. Is.

It is a perspective view which shows the Example of this invention. It is a perspective view which shows the Example of this invention. It is a top view which shows the Example of this invention. It is sectional drawing which shows the Example of this invention.

Embodiments of the present invention will be described below with reference to FIGS.

Commercial origami paper is usually square, with a large size of 15 cm square, a medium size of 11.5 cm square, and a small color paper of about 7.5 cm square. Therefore, in the present application, description will be made on the assumption that 15 cm square origami is used.

In the embodiment shown in FIG. 1, a paper pad frame 102 is attached to a side edge of a square substrate 10 of about 20 to 24 cm square, and a vertical standing hole 104 and an oblique hole 105 are provided on the upper surface of the paper pad frame 102. It is. A tapered rod 103 having a length of about 10 cm or a triangular rod 106 having a triangular cross section is detachably fitted in these holes. These upward-facing sticks can be dangerous and intrusive when not in use, so if you put them in the storage holes 107 provided inside the paper pad 102, they will not get in the way when you carry them. Easy to store in handbags. The tapered rod 103 serves as the fingertip of the other hand as described above. (The other finger is for a handicapped person). The taper rod 103 is actually 7.5 cm long so that the 15 cm square origami 20 is first folded into half a triangle and then folded again into a triangle, so that this triangular bag portion is expanded to the back. Although there is a margin, it is preferable to set it to about 10 cm.

In addition, the triangular bar 106 erected obliquely is used when a fold line is formed on an expanded portion or the like. A fold line can be formed by applying an acute angle portion of the triangular bar 106 to a position where a fold line is to be formed on the origami 20 and sliding it while pressing it with the belly of a finger. This is because the elastic anti-slip material 104 is attached to the four corners of the back surface of the substrate 10, so that the substrate 10 is difficult to move without being held down with the other hand when pressed with an oblique force.

As shown in FIG. 1, a folding plate 11 made of a substantially rectangular transparent sheet is attached to the diagonal of a rectangular substrate 10 with an adhesive tape 12 or the like, and the edge of the lower edge 111 is bent slightly to bend up. This is the insertion slot 112. When the origami 20 is inserted under the edge 111, there is almost no gap between the origami board 10 and the insertion of the origami 20 from the gap is difficult with just one hand. The origami 20 from 112 can be easily inserted into the lower portion of the edge 111 with one hand.
A straight line 101 is written on the substrate surface 10 so as to be perpendicular to the edge 111 of the folding plate 11. This is used when, for example, the crane wing 21 is raised, and the straight line 101 is aligned with the center 25 of the origami 20 inserted on the lower side so that it can be folded at a right angle. It is. Even when other types of origami papers are folded, they have conventionally been folded at a right angle in terms of the division amount, but can be folded at right angles with the center of the straight line 101 and often useful.

In the embodiment shown in FIG. 2, the folding plate 11 is attached to the straight line 101 written on the square substrate 10 with the adhesive tape 12 or the like so that the edge portion 111 becomes a right angle. Is also included in claim 1. (The shape of the substrate 101 may not be a quadrangle, but may be a triangle, a trapezoid, or other shapes, and the folding plate may be a trapezoid or a triangle instead of a rectangle.)

As shown in FIG. 3, angle lines 113 of 90 degrees, 45 degrees, 22.5 degrees, and 11.25 degrees are written starting from the edge portion 111 of the folding plate 11. Usually, the left and right side edges of the folded origami paper are pinched with the left and right fingers and the side edges are aligned and folded at an acute angle, but this is intended to facilitate folding with one hand. In particular, it is used when folding the tail part 23 and the neck part 22 with one hand, which has to be folded to 11.25 degrees, which is a narrow width and difficult with both hands, to 11.25 degrees.
This angle line 113 is frequently used not only for folding paper cranes but also for folding frogs, swallows, monkeys, and the like with many sharp corners.

In addition, as shown in FIG. 4, the elastic anti-slip material 104 is attached to every corner of the back surface of the substrate 10. When the substrate 10 and the paper pad 102 are made of wood, when they are twisted by drying, they are pressed from above. When the origami 20 is folded on the substrate 10 or the folding plate 11 with one hand, the substrate on the desk is slid while being held down with the fingers 30. In order to prevent slipping and movement, and to prevent sliding and movement even when a force is applied to the acute angle bar 106 standing obliquely. Further, although the edge portion 111 of the folding plate shown in FIG. 4 seems to be thick in the drawing, it is actually made of a thin and strong transparent plastic. However, it can be easily folded at 360 degrees. When the thickness is inevitably increased for reasons such as strength, a knife-like edge that decreases toward the tip may be used. The folding plate 11 is preferably a transparent colored plastic sheet so that the edge portion 111 can be clearly seen.

In the origami assisting tool 1 of the present invention, main parts such as the substrate 10 and the paper holding frame 102 are made of wood, paper, plastic, or the like, but wood is stronger and more flexible, and the standing hole 104 is tapered. It will be convenient because the rod 103 can be easily inserted and removed and it is difficult for the rod 103 to fall off naturally. As the number of elderly people living on pensions increases in the age of aging, they will be used for rehabilitation of fingers and brain and prevention of dementia at home and various elderly facilities. In addition, it is expected that there will be great demands such as being used as educational equipment in infant facilities. Also, if you make this origami aid as a work subject at a junior high school, etc. and donate the work to a nursing home etc. while learning simple patent technology, you can also contribute to society and get the effect of three birds with one stone Will.
