Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to balloons that play as toys.

[0002]

2. Description of the Related Art A conventional balloon is filled with helium gas and attached with a string, and is simply floated in the air, an elastic band is used to take advantage of its elasticity, or an air-filled balloon is launched by hand. I played The air of No. 35-34028
There was a yo-yo in it, but we wanted to make it easy to store and carry
Heavy, made of vinyl, floating in the air as a balloon
It was not something to play with.

[0003]

[Problems to be solved by the invention] Balloons floating in the air are mysterious for children, and it is fun to hold them for a while, but they quickly get tired, so they can be moved up and down to give movement and elasticity of rubber cords. Sex complicates the movement, but it was until then. The one with the air tried to play instead of the ball, but it was too light and unsatisfactory.

[0004]

Means for Solving the Problems Two disk-shaped balloons made of a plastic film such as polyethylene are connected by bonding or welding at a center point or at a concentric circle thereof, and a string of an appropriate length is connected to the connection portion. Was.

[0005]

[Function] When hydrogen and helium are filled and inflated, they are lifted by buoyancy, while air, carbon dioxide, etc. hang down by weight,
If the string tied to the connecting part is wrapped around the connecting part first, the balloon rotates as it rises or hangs down, the string is unwound, and when the winding is completely returned, the balloon is at the highest speed And then wind up the string in reverse.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, this is a side view of a balloon 1 of the present invention in which hydrogen is filled and raised as an example, but two identical balloons 2, 2 'are not displaced. Are connected to each other at the center of a circle, and are connected by bonding with an adhesive with a concentric circle of an appropriate size, and a strap 4 of an appropriate length is connected to the connecting portion 3.

[0007] Since the material is a polyethylene film or a laminate of nylon and polyester, or another plastic film, the connecting portion 3 is also manufactured by heat sealing the inner walls of the inner balloons first, and then each disk is formed. The peripheral portion 5 of the balloon may be heat-sealed. Then, it is also possible to use a Teflon film, printing, or the like so that the inner walls of the peripheral portion are not attached to each other and are simultaneously performed.

Normally, when the peripheral portion 5 is heat-sealed, a rectangular tube formed by laminating rectangular films and heat-sealing the long side is heat-sealed at the same time, and a check is made as shown in FIGS. Although it is assumed that the balloon 1 is provided with a valve, the more uniform the load of the balloon 1 with respect to the rotating shaft passing through the center, the better.

FIG. 2 is a cross-sectional view of the connecting portion. The connecting portion 3 is, for example, a concentric heat seal wire having a size about half the size of the balloon 1, and a cut 7 is provided. A small hole 8 may be provided at the center at the same time or before and after, so that the internal spaces of the balloons 2 and 2 'communicate with each other. When a thin nozzle or the like is inserted into the joint of the inner wall from the cut 7 and filled with hydrogen gas, the gas flows into the balloons 2 and 2 ′ from the hole 8 and expands.
Then, when the nozzle is pulled out, the joint of the inner wall up to the edge of the hole is pushed by the internal pressure, and functions as a check valve. If necessary, two heat seals are applied from the cut 7 to the hole 8 as shown by a dotted line 9 to make the flow path thinner.
The function as a check valve can also be strengthened. If the hole 8 has a sufficient distance from the cut 7, a very slight load is eccentric, but it is not always required to be at the center, and the cut may be plural.

[0099] Even if helium is used in place of hydrogen for the balloon 1, the balloon rises and is more noticeable than the one that hangs down with air, carbon dioxide, etc., but the air can inflate the balloon anywhere. . The behavior is the same for both,
When the strap 4 tied to the connecting portion 3 is first wound around the connecting portion, the balloon 1 is raised as it floats or hangs down.
Rotates, the string is rewound, and when the winding is completely returned, the balloon 1 rotates by inertia, and the string 4 is wound up with the momentum. This movement can be energized by adjusting the timing and applying a force in the opposite direction to the balloon by hand, and can be repeated as many times as necessary.

[00011]

[Effect of the invention] By adjusting the timing and applying a force in the opposite direction to the balloon by hand, energy can be imparted to the rotating up and down motion, and the energy can be repeated as many times as possible. For example, the flashy balloons floating in the air above the pedestrians in the streets and rotating while moving up and down are quite eye-catching, so they are not only toys for children but also flashy as promotional items. Yes, it is suitable because the price is low.

The technique of adjusting the timing must be mastered, but it is not difficult to get tired of it before it goes well, and it is also necessary to stop the rotation perfectly depending on the skill level, or to start the rotation from that state It will be possible to perform quite a few techniques, and since it is a deep play equipment, it will be a play equipment that is also pleasing to adults.
