Description

  This invention relates to a toy bamboo dragonfly.

  Bamboo dragonfly is a kind of toy that has been passed down for a long time, and its traditional structure is well known. As shown in FIG. 1, the conventional bamboo dragonfly cuts bamboo (or integrally molds a plastic material) to form a blade portion 1, and forms a hole at the center of the blade portion 1. One end is inserted and provided so that the shaft 2 extends vertically downward from the center bottom of the blade portion 1. When flying a bamboo dragonfly having such a structure, the bamboo dragonfly is rapidly rotated with the shaft 2 between the palms of both hands. Then, the blade part 1 rotates and the bamboo dragonfly flies.

  However, according to actual experience, the conventional bamboo dragonfly structure. The following problems were found to exist: That is, first, since the shaft 2 is fixed to the bottom surface side of the blade portion 1, when flying, the flying height cannot be raised because the shaft 2 has a certain weight.

  As a second problem, since the shaft 1 is connected to the bottom surface side of the blade 1 at the time of flight, not only interference with the blade 1 occurs but also the posture of the bamboo dragonfly flying is not elegant.

  As a third problem, the shaft 2 is fixed to the bottom surface side of the blade portion 1 and has an angle of 90 ° downward. Therefore, when the bamboo dragonfly is not used, it is inconvenient to carry or store.

  It is an object of the present invention to provide a bamboo dragonfly that is higher and can fly farther, has an elegant flight attitude, and is convenient for carrying or storing when not in use.

  Therefore, the bamboo dragonfly of the present invention has a blade portion and a shaft portion, and each blade portion is formed with a fitting portion at the opposite position in the center, and the shaft portion is fitted to the upper end of the blade portion. A fitting portion corresponding to the joint portion is formed as a fitting seat, and a shaft body having an appropriate length is extended below the fitting seat. When using, the fitting portion formed on the fitting seat of the shaft portion is inserted into the fitting portion of the blade portion, and the shaft body of the shaft portion is sandwiched between the palms of both hands and rapidly rotated. When the shaft portion is rotated, the blade portion is rapidly rotated, and the blade portion is separated from the shaft portion by a centrifugal force and flies upward. The flying posture is graceful, and when the blade is not in use, the blade portion is removed from the shaft portion, which is convenient for carrying or storing.

  The blade portion has a rectangular plate shape, and is formed as a notch groove formed by cutting inward from both sides at the center position of the blade portion. Served for insertion.

  In addition, the blade portion has a center portion, and a plurality of blades extend outward from the center portion, and two insertion holes are formed in the center portion as a fitting portion, and the shaft portion is fitted. The form used for insertion of this fitting part formed in the seat may be sufficient.

  In the fitting portion of the shaft portion, an upper end edge portion is cut out to form a concave portion, and fitting portions protruding upward are formed at both ends of the upper end edge portion.

It is the perspective view which showed the external appearance of the conventional bamboo dragonfly. It is explanatory drawing which showed the state which decomposed | disassembled the bamboo dragonfly by this device. It is the perspective view which showed the state which fitted the blade | wing part in this invention on the axis | shaft. It is explanatory drawing which showed the usage aspect of the bamboo dragonfly by this device. It is explanatory drawing which showed the bamboo dragonfly by other embodiment.

  FIG. 2 is an explanatory view of a state where the bamboo dragonfly according to the present invention is disassembled. As disclosed in the drawings, the bamboo dragonfly according to the present invention includes a blade portion 3 and a shaft portion 4. In the center of the blade portion 3, a fitting portion 31 is formed at an opposing position. In the embodiment, the blade portion 2 has a rectangular plate shape, and the fitting portion 31 is a notch groove formed by cutting inward from both sides at the center position of the blade portion 2.

  The shaft portion 4 is provided with a fitting seat 41 at the upper end. The fitting seat 41 forms the fitting portion 411 at a position corresponding to the fitting portion 31 of the blade portion 3. Further, a shaft body 42 having an appropriate length extends below the fitting seat 41. In the embodiment, the fitting portion 411 is a concave portion formed by cutting out the upper edge portion of the fitting seat 41. By forming the concave portion, the fitting portion 411 projects upward at both ends of the upper edge portion. A portion 411 is formed.

  A bamboo dragonfly is comprised by each member mentioned above. When using, the fitting portion 411 formed on the fitting seat 41 of the shaft portion 4 is inserted into the fitting portion 31 of the blade portion 3, and the shaft body 42 of the shaft portion 4 is sandwiched between the palms of both hands and rapidly rotated. Let When the shaft portion 4 is rotated, the blade portion 3 is rapidly rotated, and the blade portion 3 is separated from the shaft portion 4 by the centrifugal force and flies upward. Therefore, the weight of the bamboo dragonfly is reduced, and it is possible to fly higher and farther, and the flying posture is graceful. By removing the blade 3 from the shaft 4 when not in use, it is convenient for both carrying and storage.

  In FIG. 3, the state which attached the blade | wing part 3 in this invention to the axial part 4 is disclosed. As disclosed in the drawings, when a bamboo dragonfly according to the present invention is used, the fitting portion 411 formed on the fitting seat 41 of the shaft portion 4 is inserted into the fitting portion 31 of the blade portion 3, and the shaft portion 4 is inserted. Position below the blade 3. Therefore, it becomes an aspect like a conventional bamboo dragonfly, and the shaft body 42 of the shaft portion 4 is sandwiched between palms of both hands like a conventional bamboo dragonfly and rapidly rotated. When the shaft portion 4 is rotated, the blade portion 3 is rapidly rotated, and the blade portion 3 is separated from the shaft portion 4 by the centrifugal force and flies upward.

  FIG. 4 is an explanatory view showing how the bamboo dragonfly is used according to the present invention. As disclosed in the drawings, when the bamboo dragonfly according to the present invention is used, the fitting portion 411 formed on the fitting seat 41 of the shaft portion 4 is used as the fitting portion 31 of the blade portion 3 as disclosed in FIG. The shaft portion 4 is positioned below the blade portion 3 by being inserted. Further, the shaft body 42 of the shaft portion 4 is sandwiched between the palms of both hands and rapidly rotated. When the shaft portion 4 rotates, the blade portion 3 rotates rapidly. When the blade portion 3 is rotated, the blade portion 3 is separated from the shaft portion 4 by a centrifugal force and flies upward. In this case, since the blade portion 3 does not connect any shaft body as seen in the conventional bamboo dragonfly downward, the weight of the blade portion 3 of the bamboo dragonfly is reduced and can fly higher and farther. Therefore, the fun of flying bamboo dragonflies increases. And since the blade | wing part 3 flies independently, an elegant flight attitude | position is obtained.

  FIG. 5 is a perspective view of a bamboo dragonfly according to another embodiment. As disclosed in the drawings, the blade portion 3 in the present invention includes not only the blades having a rectangular plate shape as in the above-described embodiments, but also the blade portion 3 includes the center portion 32 and the center portion 32. A plurality of blades 33 may be extended outwardly from each other (in the embodiment disclosed in the drawings, the three blades 3 are provided and the three blades 3 are arranged at equal intervals). Further, two insertion holes 32 are formed in the center portion 32 to form a fitting portion 31, which is used for insertion of the fitting portion 411 formed in the fitting seat 41 of the shaft portion 4. The shaft portion 4 is positioned below the blade portion 3 by inserting the fitting portion 411 formed on the fitting seat 41 of the shaft portion 4 into the fitting portion 31. When the shaft 42 is rapidly rotated with the 42 interposed therebetween, the blade portion 3 rotates rapidly, and the blade portion 3 is separated from the shaft portion 4 by the centrifugal force and flies upward.
