Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a handleless fan that uses a bi-folded mount body as the master and sub-fan.

<Prior Art> Recently, with the diversification of hobbies and the development of new materials, in addition to the traditional patterned fans, simple fans that use a cardboard mount as the fan itself have appeared and are becoming popular as gifts and souvenirs. For example, circular fans made by punching a cardboard into a circle are known.
In this case, the structure of the fan consists at most of a small finger hole drilled in the base (lower part) of the circular mount body, and as a result, even if the desired pattern is printed on the front and back, it is not interesting at all, and the current situation is that it is simply thrown away.

<Problems to be solved by the invention> In view of the above-mentioned circumstances, the purpose of the present invention is to provide a simple fan that incorporates a small fan that swings with a spring into the fan mount body and aims for interesting movement. This is what I did.

<Means for solving the problem> The present invention symmetrically forms a fan mount body of a predetermined shape with an appropriate folding width interposed in the middle to form a bifold line using a thin plate member such as cardboard or plastic board. At the same time, a small piece of fan mount is punched out in the center of each outer part of the left and right fan mount main bodies, with a small gap interposed in the entire periphery of the small fan mount, and these two fan mount main bodies are overlapped and pasted. A small fan mount, in which a pair of small fan mount pieces are stacked and pasted, is arranged in the cut-out window position formed by removing the small fan mount pieces from the main fan mount, and the lower end of the small fan mount and The main fan mount is hinged to the lower edge of the cutout window using a small thin plate spring, and the large main fan mount and the small fan mount form a double fan.

<Function> Due to the above-mentioned structure, when using the fan, just like conventional handleless fans, if you hold the lower edge of the main fan mount and perform the specified fan movements, a cool breeze will be generated from the main fan mount itself. At the same time, the center of gravity of the small fan mount built into the cut-out window in the center of the top is located above the connection point of the thin leaf spring, which causes it to oscillate relative to the main fan mount, creating an interesting movement of the fan. becomes.

<Example> Hereinafter, the present invention will be explained based on the drawings of the example.

The drawing shows a circular fan. Reference numeral 1 is a circular fan mount body made of cardboard or plastic board with an appropriate thickness, with a folding width 2 that forms a bifold line a in the middle, and is symmetrically formed. A small fan mount piece 3 having a similar shape and a small diameter is placed at the center of each outer part of the mount main body 1 centered on the bifold part.
The small fan mount piece 3 is punched out so as to form a small gap 4 around the entire circumference. The two fan mount bodies 1, 1 connected in series with the folding width 2 are folded in half and glued together to form the main fan mount 5. At the time of this adhesion, the small fan mount piece 3 is punched out, and the missing pieces are removed. The lower half of a steel thin plate spring 7 having an appropriate length is inserted into the lower edge joint of the window 6 and fixed. The pair of small fan mount pieces 3, which incorporate the upper half of the thin plate spring 7 protruding into the opening window 6 into the opening window 6;
3, and the small fan mount piece 3, 3
The small fan mount 8 formed by the above is connected by a hinge, and the whole becomes a large and small double fan 9. Reference numeral 10 indicates a small hole for placing a finger in the center of the lower part of the main fan mount 5, and 11 indicates the main fan mount 5 and the small fan mount 8.
This is a display area with images, characters, etc. printed on the front and back sides of the screen.

When using this fan, first grasp the lower edge of the main fan mount 5, which has a large diameter like conventional fans of this type. At this time, if necessary, place the thumb toward the small finger hole 10 for a secure grip.

Here, if the main fan mount 5 is shaken from side to side, a cool breeze will be generated by the surface of the mount. In this case, the small fan mount 8 also begins to swing out at the center of the upper part of the main fan mount 5 via the thin plate spring 7.
The small fan mount 8 emphatically swings due to its own weight and the elasticity of the thin plate spring 7 at the lower end, and swings at a larger angle than the main fan mount 5, making it visually enjoyable to use the fan. Of course, even if the small fan mount 8 itself generates a certain amount of cool air, and in this case, the swing angle will be large, so it is
As a result, a larger air volume can be obtained than with a single piece.

<Effects of the invention> As mentioned above, the fan of the present invention has a large and small double fan configuration in which a small fan mount connected by a thin plate spring is placed in the upper center of the main fan mount which is folded in half and has a predetermined shape. This results in a handleless fan that is extremely simple and increases the amount of airflow. What's more, the small fan mount built into the inside sways more than the main fan mount due to the repulsion of the spring, increasing the amount of airflow and creating an interesting fan movement. especially,
For children, etc., it is fun to use the fan, and together with the appropriate printed information placed on the front and back sides, it has the greatest advertising effect, and is ideal as a pattern and as a souvenir. In addition, the present invention can be manufactured by simple operations such as punching, bending, and pasting cardboard, so it has practical effects such as being an inexpensive product that can be mass-produced.
