Next, the columnar connector according to the present invention will be described with reference to the drawings.
In addition, this description is an example and is not limited only to this shape and situation.
FIG. 1 shows a connecting part (1) according to the present invention, and includes various modifications. The cylindrical connecting member 1 is a part of a straw, and is formed by cutting the columnar cylindrical body 5 shown in FIG. 5 into about 3 cm and widening one end to form a flare.
The straw itself may be used without cutting.
For example, a popular product having a diameter of 6 mm can be used.
The cylindrical tubular body 5 can be connected to the tubular connecting member 1 as shown in FIG. This is because the outer shape of the cylindrical connecting member 1 slightly increases due to the insertion pressure of the cylindrical cylindrical body 5.
As a result of the experiment, both the cylindrical connecting member 1 and the cylindrical cylindrical body 5 can be connected and detached within the range of elastic deformation by selecting the material.
That is, it can be disassembled into a state where reconnection is possible.
Moreover, it is possible to maintain a practical linear shape when connected. For this reason, by making the other end of the cylindrical connecting member 1 into a flared shape, both ends are connected to each other so that the cylindrical cylindrical body 5 is connected to both ends, and the cylindrical cylindrical body 5 is straight. Can be extended.
The shape of the flare portion 12 is to guide the insertion of the cylindrical cylindrical body 5 and desirably has a smooth curvature without a step.
FIG. 2 shows a cylindrical connecting member 2 according to the present invention, and the columnar cylindrical body 5 is appropriately cut or used without being cut. A hole (hole) having a slightly smaller diameter is formed from the cylindrical tubular body 5.
A commercially available document punch or the like can be used for opening the hole. The opening diameter of the drilling machine is usually 6 mm.
When the cylindrical tubular body 5 is inserted into the hole portion 21, the hole portion 21 is slightly elastically deformed, and the cylindrical tubular body 5 can be held slidably and slidably rotated. (Fig. 7)
Sliding is a connection that contacts each other and has an appropriate holding force. For example, the sliding force is a holding force that does not easily come out even if the inserted straw is swung, but can be easily separated when pulled out with a finger.
The cylindrical connecting member 22 represents a modification, and is provided with a plurality of hole portions 21. Various modifications can be configured by changing the interval and the relative angle between the plurality of hole portions 21.
This case is shown as a cross section 22-1 of the cylindrical connecting member 22.
FIG. 3 is an explanatory view showing the connecting portion body (3) according to the present invention, in which the flare portion 12 is provided at one end portion of the cylindrical connecting member 2 described above. Similarly, the connection body 31 which provided the cylindrical connection member 2 in the both-ends connection body 10 and the connection body 32 which provided the some hole 21 in the cylindrical connection member 22 are shown.
FIG. 4 shows a connecting part 4 according to the present invention, and the connecting part 4 has an outer shape that can be inserted into the cylindrical connecting member 1 without sliding.
Actually, it is a straw having a diameter of 5 mm, and when a straw having a diameter of 6 mm is inserted, it is theoretically not in contact and can be inserted without actually being in contact.
A slight contact between the resins, unlike sliding, does not have a holding force.
Here, the cylindrical tubular body 5 is provided with a flare 41, which indicates that the cylindrical tubular member 5 is slidably connected to the inside of the tubular connecting member 1. Thereby, it can be made to slide-connect in the left-right direction and rotation direction of a figure.
When the connecting member 4 is further moved in the right direction in the figure, the flare 41 is detached from the cylindrical connecting member 1. (Fig. 8)
In this case, the cylindrical connecting member 1 and the connecting portion body 4 are related without sliding, and the cylindrical connecting member 1 is not easily separated from the connecting portion body 4 and has a certain securing force.
This is because the flare 41 of the connecting part 4 is deformed within the inner diameter of the cylindrical connecting member 1 and then is removed from the inner diameter of the cylindrical connecting member 1 so that the elastic deformation of the flare 41 is restored. This is because the inner diameter of the cylindrical connecting member 1 is exceeded.
FIG. 9 shows that the connection body described above can be used in various combinations.
As an example, the combination 90 is the cylindrical connection member 1 connected to the connection body 31, the combination 91 is the connection body 31 and the cylindrical connection member 1, and the combination 92 is a cylindrical connection to both ends of the cylindrical connection member 2. This is an example in which the member 1 and the cylindrical connecting member 1 are combined.
In addition, it can be said that the minimum length of a connection body is the length which can provide the flare part 12 and the hole part 21. FIG.
FIG. 10 shows an example in which the above-described connecting body and origami 100 are combined to form a windmill.

The origami 100 is provided with four cuts 101 as shown in the figure, one hole 102 at the center, and four ends. This hole can be provided by punching. FIG. 10-1 is an explanation of assembling a single windmill. When a normal 15 cm origami 100 is used for the origami 100, first, the central hole 102 of the origami 100 is formed in the tubular connecting member 1 (diameter 6 mm and length 35 mm). Insert.
Next, a spacer (7 mm diameter, 25 mm length) is inserted, and holes 102 at four corners are inserted (because it is a part that becomes a wing of a windmill, it is inserted so as to be gently rolled inward).
After inserting the holes 102 at the four corners into the cylindrical connecting member 1 protruding above the spacer 103, the cylindrical connecting member 1 (10 mm) is inserted.
Thereby, the windmill 110 is made. (Fig. 10-2)
In the center of the windmill 110, the connection part body 4 (70 mm) is inserted until it comes out to the other end of the cylindrical connection member 1.
Thereby, by holding the connection part body 4, the windmill 110 which used the connection part body 4 as the rotating shaft rotates freely with a slight wind. (Fig. 10-2)
By inserting the connecting portion 4 into the cylindrical connecting member 1 connected to the cylindrical tubular body 5, a hand-held windmill that supports the cylindrical tubular body 5 can be configured.
In this case, since the cylindrical connection member 1 is inserted into both ends of the connection body 10 at both ends, two wind turbines 110 can be attached. (Fig. 10-3)
Naturally, the diameter of the windmill 110 can be changed variously by changing the size of the origami 100.
In that case, you may change suitably the length of the cylindrical connection member 1 grade | etc.,.
FIG. 10-4 shows a state in which the windmill 110 is connected to the cylindrical tubular body 5, and in particular, when the connecting portion body 4 is inserted, the connection is made by exceeding the rear end portion of the tubular connecting member 1. This indicates that the flare of the body 4 is slightly returned, so that a clicking feeling can be obtained and the wind turbine 110 has an appropriate holding force that does not naturally fall off.
Even in this case, the windmill 110 can be pulled out of the tubular connection member 1 together with the windmill 110 while holding the tip of the connection body 4.

In other words, it is possible to attach and detach as appropriate, so that the color and shape of the windmill can be changed, the direction of the windmill 110 can also be changed and inserted, the direction of the reacting wind, or origami It is easy to change the direction of rotation by attaching 100 different folding methods. By attaching a plurality of these, it is possible to provide a wind turbine having a large application range.
FIG. 11 shows another example of a modeled object using the connection body according to the above, and shows a case where a twin propeller airplane is configured.
The windmill 110, the cylindrical cylindrical body 5, the connection body 31 and the like have designated the use of the above-described components.
In this case, the horizontal tail and the vertical tail are cut into the cylindrical tubular body 5 as appropriate to form a wing 111. The present invention is not limited to this, and it is described that various various structures can be made. For example, a structure of an automobile can be formed and used for a simple strength test.
In addition, if a resin water pipe, a metal pipe or the like is used instead of a straw, it can be applied to a material according to the strength for the purpose of the structure, such as a simple assembling tent, a greenhouse or a fence.
As shown in FIG. 12, a windmill frame 121 that can be attached to a head or a hat can be configured.

For arts and crafts education in elementary and junior high schools, for creating molecular structures in chemistry, for providing entertainment for welfare facilities for the elderly, for rehabilitation equipment such as nerve muscles, magazine supplements, etc. It can be used as a creation for windmills that can be provided safely and inexpensively in various applications such as appendices and display for merchandise at stores.
A windmill or the like can be assembled as a part on paper, so it is easy to put a photograph, wording, etc.
