It was difficult for kindergarten children to carry out work such as shaving with a small sword because it was difficult and dangerous, but we devised it so that it could be enjoyed like a bamboo dragonfly by a simple method. A blade (1) of a bamboo dragonfly is made of a hard vinyl chloride thin plate, a hole (2) is made in the center of the blade (1), and a bamboo shaft (3) is fitted and fixed to the blade (1). The central part of () is heated and the left and right are alternately twisted to form a propeller blade.

[Technical field to which the device belongs]

本考案は幼稚園児向きの教育用遊具に関する。 The present invention relates to a playground equipment for kindergarten children.

【０００２】[0002]

[Prior art]

従来遊具に竹トンボがあった。竹を割り、小刀で削り、穴をあけ、プロペラを形成して、軸を削って固着させる等の幾つかの工程は熟練した年長者でもむづかしいものであった。それ故に幼児などには危険も伴って、できなかった。 There was a bamboo dragonfly in the playground equipment. Some steps, such as cracking bamboo, shaving with a sword, making holes, forming a propeller, and shaving the shaft to fix it, were difficult even for a skilled senior. Therefore, infants and others could not do it because of the danger.

[Problems to be solved by the device]

竹トンボの工作が以上のような工程で、幼児ではできないため、これを簡単で安価に量産し、大勢の子供達が均等に遊べるようにと考え、トンボの羽根（１）に硬質塩化ビニールの薄板を用い、竹トンボ同様の作動するようにしたビニトンボである。 Since the production of bamboo dragonfly is the above process, which cannot be done by infants, mass production of this is easy and inexpensive, and it is thought that many children can play evenly. It is a vinyl dragonfly that uses a thin plate and operates in the same way as a bamboo dragonfly.

[Means for Solving the Problems]

本考案は硬質塩化ビニール板の厚さ約１ミリ、巾１２ミリ〜１５ミリ、長さ約１００ミリ〜１５０ミリの羽根（１）の中央に約２．８ミリの穴（２）をあけ、約３ミリ径の竹軸（３）を嵌めて接着剤で固定する。羽根（１）の中央部分を加熱して適宜の角度で交互にねじり、プロペラ翼のビニトンボに構成した。 According to the present invention, a hard vinyl chloride plate having a thickness of about 1 mm, a width of 12 mm to 15 mm, and a length of about 100 mm to 150 mm has a hole (2) of about 2.8 mm formed at the center of the blade (1). A bamboo shaft (3) with a diameter of about 3 mm is fitted and fixed with an adhesive. The central portion of the blade (1) was heated and alternately twisted at an appropriate angle to form a propeller blade binitombo.

[Embodiment of device]

図によって説明する。図１のビニトンボの羽根（１）は硬質塩化ビニールである。この羽根（１）の中央に約２．８ミリの穴（２）をあけ約３ミリ径の竹軸（３）の先端を熱し、この穴（２）にさしこんで接着剤で固定する。羽根（１）の中央部分を加熱して羽根の左右の角度を交互にねじりプロペラ翼にする。この工程は幼稚園児でもできて危険がない。羽根（１）のねじり具合が工夫次第でよくとぶようにできる。 It will be described with reference to the drawings. The blade (1) of the Binito dragonfly in FIG. 1 is hard vinyl chloride. A hole (2) of about 2.8 mm is made in the center of this blade (1) to heat the tip of a bamboo shaft (3) with a diameter of about 3 mm, and it is inserted into this hole (2) and fixed with an adhesive. . The central part of the blade (1) is heated to alternately twist the left and right angles of the blade to form a propeller blade. This process can be done even in kindergarten children and there is no danger. The twist of the blade (1) can be adjusted so that it can fly well.

【Example】

実施例をさらに説明すると、図１に示すものはビニトンボの羽根の斜視図である。トンボの羽根は硬質ビニール板を用いてあり、中央部に軸取付穴（２）を設けてある。図２の竹軸（３）の先端を穴（２）にさしこんで固着し、羽根（１）の中央部を加熱して交互にねじりプロペラ翼にする。 To further explain the embodiment, what is shown in FIG. 1 is a perspective view of the blades of a binito dragonfly. The blades of the dragonfly are made of hard vinyl and have a shaft mounting hole (2) in the center. The tip of the bamboo shaft (3) in FIG. 2 is inserted into the hole (2) and fixed, and the central portion of the blade (1) is heated to alternately form a twisted propeller blade.

[Effect of device]

幼稚園児にはむづかしい竹トンボの工作に代り、ビニトンボは工作が簡単で幼児の遊具には適している。このような工作も創意工夫が必要で羽根（１）のねじり具合と、竹軸（３）との重量のバランスの具合で遠くへとぶもの、高くとぶもの、等ができる。この工作は実行して見て、意外にやさしく面白くて良い体験になるものである。 Instead of making bamboo dragonflies, which are difficult for kindergarten children, Vinito dragonflies are easy to make and are suitable for play equipment for young children. This kind of work also requires some ingenuity, and depending on the balance of the twisting of the blade (1) and the weight of the bamboo shaft (3), it is possible to make things that are far away, those that are high, and so on. This work will be a surprisingly easy, interesting and good experience.
