Description

[Detailed description of the invention] (Technical field) This invention relates to a floating toy that is played by floating on the surface of water.Moreover, the invention relates to a floating toy that is played by floating on the surface of water. This invention relates to a floating toy that allows you to enjoy watching the movements of its movable parts.

(Purpose of the invention) This invention is an unprecedented new idea that utilizes the relative motion between the rotating outer shell and the stationary contents installed inside it to move the movable part installed in the stationary contents. It was made for the purpose of providing floating toys.

(Summary of the invention) The floating toy of this invention is a transparent, translucent or colored transparent body whose interior can be seen through, and has a rotationally symmetrical shape such as a hollow sphere or cylinder that can easily rotate while floating on the water surface. An outer shell, a stationary inner shell that is sufficiently heavy at the bottom and is movably suspended from a shaft that is installed and fixed within the outer shell along its axis of rotation, and the relative movement between the shaft and the stationary inner shell, that is, a spherical outer shell. It consists of a movable part installed in a stationary body so as to be operated by utilizing the movement of a shaft that rotates integrally with the body.

(Function and Effect) Therefore, according to the present invention, when a floating toy is floated on the water surface and its spherical outer shell is rotated around its axis,
This floating toy rotates while remaining stationary at one point on the water surface, so you can enjoy seeing through the still contents and the movement of the moving parts.

Moreover, since the shaft rotates together with the spherical outer shell and moves the movable part in the stationary contents, for example, the stationary contents can be made into the shape of a pom-pom boat,
If the movable part is shaped to resemble smoke rising from the chimney of the pom-pom boat, it will create an interesting scenery as if the pom-pom boat was blowing up smoke as it moves forward. Therefore, it is suitable as a bath toy for infants.

(Example) What is shown in FIGS. 1 to 3 is a floating toy as an example of the present invention, which is constructed as follows.

In the figure, 1 is a transparent plastic spherical outer shell formed as a relatively thin hollow sphere with uniform thickness, 2 is a shaft installed and fixed at a position passing through the center of the spherical outer shell 1, and 3 is the shaft 2. The stationary interior is suspended in a floating state and has the shape of a pom-pom boat, and 4 is a movable member that moves up and down in the chimney portion 5 of the pom-pom boat.

The shaft 2 is designed as a square shaft (Fig. 5),
Both ends thereof are fitted and fixed into the thick portions 1', 1' of the spherical outer shell 1, and are installed thereon.

The stationary contents 3 include an upper case 3a and a lower case 3b made of opaque plastic, as shown in FIG.
It is formed as a hollow body that is fitted and connected with
In addition, the shaft 2
The weight 6 is fixed to the lower part of the lower case 3b with screws 7, so it always remains stationary despite the rotation of the spherical outer shell 1. It is said that

Moreover, the mechanism for raising and lowering the movable member 4 is configured as follows.

That is, the driving gear 10 is integrally fixed to a substantially central portion of the shaft 2 (substantially the central portion within the stationary body 3) via a circular tube 8. On the other hand, two gears 12 and 13 that mesh with the drive gear 10 in sequence are installed on a support plate 11 integrally molded with the upper case 3a, forming a so-called speed increasing gear train. A crank 14 is provided integrally with the.
A pin 15 is attached to one end of the crank 14, and a balance weight 16 is attached to the other end.

At the lower end of the vertical support rod 17 of the movable member 4,
A driven frame 19 having a substantially horizontally long guide groove 18
is fixed, and the pin 15 is inserted into the guide groove 18 thereof.

In other words, even if the spherical outer shell 1 rotates, the still contents 3
The shaft 2 remains stationary, whereas the shaft 2 rotates together with the spherical outer shell 1, and the rotation of the driving gear 10 is transmitted to the crank 14 via the gears 12 and 13. The rotation of the crank 14 is converted into the vertical movement of the support rod 17 by the relationship between the pin 15 and the guide groove 18. Therefore, from the outside, the movable member 4 imitating smoke
This is visually recognized as an upward and downward movement.
