Description

[Detailed explanation of the invention] () Purpose of the invention Industrial application field This invention relates to origami crane-shaped decorations used at various events, campaigns, etc., and can be cut out without damaging the original image of the origami crane. You can assemble the obtained parts with one touch.

Prior Art Origami cranes have been familiar for a long time, and there is something that touches the heart of each person. Therefore, if you use these origami cranes as props for campaigns and events such as New Year's and year-end gifts, you can create an effective production that appeals to the hearts of Japanese people.

The origami cranes that have been used as decorations up until now were just ``origami cranes,'' made from folded pieces of paper.

In addition, it can be folded into a folding screen shape with two punched body plates as another form.
There was also a model that resembled a crane by attaching parts that formed a disk shape when opened to look like wings and attached to the body part.

Problems that the invention aims to solve However, the ones that have been used in the past have not always been completely satisfactory, and since the shape of actual origami cranes is real, there should be no dissatisfaction. However, there are problems in manufacturing and using them as decorations, as they must be manufactured by hand and the quality may vary. In addition, when it was used, it had to be shaped each time by inflating it with air and bending the wings, and it could not be made from very thick paper, so there were concerns about its strength.

Next, the one in which the body member and the blade member are provided separately,
They can be produced in large quantities and can be assembled with one touch, so I have no complaints about using them as decorations, but they are far removed from the image of origami cranes, and the effects of the decorations are naturally different. . The same can be said for things you assemble like paper crafts.

Therefore, this invention proposes a simple assembly-type origami crane that retains the image of an origami crane, can be mass-produced, and can be assembled with one touch.

() Structure of the invention Specific means for solving the problem A cylindrical body member formed of front and rear and left and right side plates having a valley fold line on the longitudinal center line, a neck, a tail, and a neck having a mountain fold line on the longitudinal center line. and a wing member, and the neck or tail member is connected to the lower part of the front and rear side plates of the body member by folding and rising up via a mountain-shaped horizontal fold line, and the neck or tail member is connected to the upper part of the left and right side plates via a valley-shaped horizontal fold line. The wing members that can be folded and reclined are arranged in series, and at least one pair of the front and rear side plates or the left and right side plates are tied together with a string.

Example In order to make the present invention more clear, we will explain it in detail according to the example shown in the drawings below.

A left side plate 4, a front side plate 2, a right side plate 5, and a rear side plate 3, each tapering downward on both sides and having a valley fold line _l1 on the vertical center line, are successively connected from the left to the right via the fold line. to form body member 1. Next, in the lower part of the front and rear side plates 2 and 3 of the body member 1, a mountain-shaped transverse fold line L ₁ whose bending point is located at the lower end of the valley fold line L ₁ of the front and rear side plates 2 and 3, respectively, is inserted. Said valley fold line l ₁
A triangular neck member 6 and a triangular tail member 7 having a mountain fold line l ₂ on the vertical center line are connected in a straight line. Similarly, on the upper part of the left and right side plates 3 and 4, respectively,
A pentagonal blade having a mountain fold line L ₂ on a vertical center line that is linearly connected to the valley fold line L ₁ through a valley-like transverse fold line L ₂ whose bending point is located at the upper end of the valley fold line L ₁ of the right side plates 3 and 4. Components 8 and 9 are installed consecutively.

The above is the basic configuration of the main body of the present invention, but to explain in more detail, there is a mountain-shaped transverse fold line L on the lower edge of the neck member 6, the bending point of which is located on the mountain fold line _L2 of the neck member 6. A beak 10 is formed through ₃ . In addition, the upper ends of the left and right side plates 4 and 5 are made to protrude in a triangular shape to imitate a real origami crane, and the lower ends are cut out in a valley shape to correspond to the mountain-like transverse fold lines of the front and rear side plates 2 and 3. .

Furthermore, a string 20 with a locking member 21 attached at one end is passed through the flat member first from the lower left corner of the left side plate 4, and then sequentially from the lower right corner of the rear side plate 3 to the center of the valley fold line _l1 of the rear side plate. part, the valley fold line l ₁ of the front side plate 2
Expose from the center, the top of the valley fold line of the front side plate, and finally the top of the valley fold line _l1 of the rear side plate 3. All the above operations are performed through holes 30 provided in each side plate. Next, by pulling the string 20, the torso member 1 becomes cylindrical with the left side of the left side plate 4 and the right side of the rear side plate 3 coming into contact with each other, and the corner side plates of the torso member 1 are bent through the valley fold line. In particular, the front and rear side plates 2 and 3 connected by the string 20 are tied together so that their valley fold line portions are in contact with each other. At this time, in conjunction with the movement of the body member, the neck and tail members 6 and 7 bend upward and stand up via the respective mountain and trough transverse fold lines _L1 and _L2 , and the beak of the neck member protrudes forward, The wing members 8 and 9 are folded downward and lie down, allowing the assembly to look almost the same as a real origami crane. Additionally, the open end of the string 20 can be used as it is as a hanging string.

In this example, by passing the string as described above, it was possible to make the body member into a cylindrical shape without using adhesive material, etc. However, the present invention is not necessarily limited to this form, and the body member can be made into a cylinder shape in advance. If an adhesive plate or the like is provided on one side of the member and the adhesive plate is used to form a cylindrical shape, the string can be attached at least to the front, between the rear plates, or to the left,
The purpose is achieved by simply passing one pair of right side panels together. You can also decide where to pass the string on each side plate, but the best one is
It is on each valley fold line. This is because the valley fold line is placed on the vertical center line of each side plate, so when assembled,
It will be assembled in an orderly manner with no distortion.

To transport and store this device, it is possible to leave it as a blank, but even when the body member is in a cylindrical shape, the front and rear side plates can be folded in half to sandwich the neck and tail members, which are still standing up. By folding it in this way, the left and right side panels open and the blade members rise at the same time, making the whole thing flat. To assemble from this state, simply unfold the front and rear plates again and it will be done automatically.

() Effect of the invention As mentioned above, this invention starts from a single blank.
You can make beautiful origami cranes without damaging the image of real origami cranes. What's more, since the assembly can be done with just one touch by pulling the attached string, combined with the above advantages, it can be easily manufactured using fewer materials. In addition, since it is possible to use fairly thick paperboard as the material, even relatively large items can have sufficient strength. Furthermore, it can be folded flat for easy transportation and storage.
