Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a jet-operated toy that is played by rotating a rotary nozzle or floating a lightweight ball in the air using the air jet force.

[Conventional technology]

Conventionally, there has been provided a base that has a jet nozzle protruding from the center of an upper wall and is capable of blowing air upward from the center hole of the jet through an air supply hose connected to the lower end of the nozzle, and this base. a rotary disk having a nozzle port which is rotatably fitted into the fumarole port in the center and having a small diameter fume nozzle hole communicating with the fumarole center hole at the upper end of the nozzle port; A T-shaped ball tray that is fixedly fitted and removably fitted into the nozzle opening of the rotary disk and rotated in one direction by blowing air backward in the rotational direction from the front and rear blowholes provided at both ends. It is equipped with a fume rotating nozzle, and a lightweight ball that is placed above the rotary disk nozzle opening when the fume rotating nozzle is removed and is pushed up into the air and floats by the air ejected from the fume nozzle hole of the nozzle opening. Blow-powered toys are known.

[Problem that the invention attempts to solve]

The conventional jet-operated toy has a structure in which a ball tray is fixed on a base, and a rotary disk can freely rotate between the ball tray and the base.
When the ball is floating in the air with the jet rotating nozzle removed, air leaks from between the rotations of the rotary disk, causing the problem that the lightweight ball cannot be effectively pushed up into the air and floated.

[Means for Solving the Problems] In order to solve the above-mentioned conventional problems, this invention has a ball tray that is rotated in one direction at a portion where the cylindrical opening of the base and the outer cylindrical opening of the ball tray are fitted. When the ball tray is rotated in the other direction, the cylindrical mouth of the saucer is pressed against the rotary plate flange, and the lower surface of the flange is pressed against the upper wall of the base. This is characterized by the provision of an engaging means for lowering the saucer so as to bring it into close contact.

[Effect]

In the jet-operated toy having the above structure, when the ball tray is rotated in one direction, the tray can be raised by the action of the engaging means so that the cylindrical mouth of the tray is separated upward from the rotating disk flange. Good rotation of the jet rotating nozzle attached to the rotary disk nozzle port can be ensured. Furthermore, when the ball receiver is rotated in the other direction with the jet rotating nozzle removed, the engagement means can lower the receiver so that the cylindrical mouth of the receiver is pressed against the rotating disk flange. Since the rotary disk flange is closely attached to the upper wall surface of the base, the problem of air leakage when using the ball floating in the air can be solved.

It is a rotary disk in which a small-diameter jet nozzle hole 8a communicating with the jet center hole 2a is provided at the upper end of the nozzle port 8, and a paper folding doll (not shown) is mounted on this rotary disk to straddle the jet rotary nozzle 11, which will be described later. ) is provided with an insert portion 10 for inserting and fixing the same.

Reference numeral 12 denotes a ball receiver having a cylindrical port 14 hanging down into the base cylindrical port 13 and an outer cylindrical port 15 rotatably fitted to the outside of the base cylindrical port 13 on the lower side of the receiver portion 13, and 11 the rotary disk. Front and rear blowholes 11a, 1 are removably fitted into the nozzle ports 8 of 7 and provided at both ends.
1b is a T-shaped jet rotating nozzle which is rotated in the direction of the arrow in FIG. 3 by jetting air backward in the rotational direction as shown in FIG. The ball is a lightweight ball made of polystyrene foam or the like that is placed on top of the nozzle and is pushed up into the air and floats as shown in FIG.

By being closely attached to the upper wall surface 1a of the base as shown in FIG. 4, it is possible to solve the problem of air leakage when using a ball floating in the air.

[Effect of idea]

Since the jet-operated toy of this invention is equipped with the above-mentioned engagement means 17, air leaks from between the rotations of the rotary disk 7 when the jet-rotating nozzle 11 is removed and the ball is floating in the air. The conventional problems can be solved, and the lightweight ball 16 can be effectively pushed up and floated in the air.
