Description

[Detailed explanation of the idea] Industrial applications This idea concerns tops.

Prior Art and Its Disadvantages The main body of a conventional top is made of a solid material whose shape remains constant, and the grounding shaft is fixed to the main body and protrudes.

Therefore, the volume of the top remains constant both when not in use and when it is in use, making it inconvenient to carry and store.In particular, when running while carrying a top in a pocket, the top may easily fall on the road or the like due to the momentum of tripping and falling. There were cases where a top was stored between the body and applied a significant recoil force locally to the body, or the spindle of the top could pierce the body, causing serious injury.

Technical Problems to be Solved In view of the above points, this invention is convenient to carry when not in use, and prevents serious injury caused by the top even if the person carrying the top falls down. With the goal.

Solution to the Problem In order to solve the above problems, this invention is made of a soft synthetic resin bag that can inflate the main body with air or other fluid, and can also drain the fluid and fold it flat. The present invention is characterized in that the plug of a blowing pipe with a plug used for supplying or discharging the fluid is used as a ground shaft.

Function: When in use, air or other fluid is supplied to the top body through the blow tube, and the stopper is inserted to maintain the top body in an inflated state. Then, the tip of the stopper of the blowing tube is grounded, and rotational force is applied by hand or with a thread wound around the ground shaft to rotate it.

When not in use, remove the stopper, press the top body with your hand to draw out the fluid from the blowing tube, and fold the top body flat.

Embodiment of this invention Next, an embodiment of this invention will be described based on the drawings.

1 is a top body made of a bag made of soft synthetic resin, such as vinyl chloride resin. It is formed symmetrically with respect to a vertical plane. The shape can be an ellipsoid, a donut, a mushroom, a spindle, or any other arbitrary shape. A blowing tube 2 is protruded from the bottom for supplying air or other fluid to the top body or discharging the supplied fluid from the top body, and this blowing tube has a small tip. A stopper 3 formed into a hemispherical shape or having another roundness is provided so as to be freely inserted and removed. A stopper 3a formed, for example, in the shape of a flange is provided on the stopper to limit the depth of insertion so that the stopper is not inserted too far and becomes difficult to remove.

With this configuration, when the stopper 3 is removed, air or other fluid is blown into the blowing tube 2 to inflate the main body 1, and the stopper 3 is inserted into the blowing tube 2 again and fixed, the top body 1 is fixed as shown in FIG. The top has the shape of a top body 1 as a rotating body and a stoppered blowing pipe 2 as a grounding axis.

Since the stopper has a rounded tip, for example, by holding the main body of the top with both hands and applying a rotational force around a vertical line to release it on a flat surface, or by winding a thread around the blowing tube 2, By releasing the top from the hand onto a flat surface and simultaneously pulling the string in the opposite direction to apply a rotational force, it is possible to rotate the top with the stoppered blowing tube 2 as the rotation axis.

When the stopper is provided with the stopper 3a, there is an advantage that the thread can be easily wound around the rotating shaft.

The stopper 3 may be formed so as to be separable from the blowing tube, as shown in FIG. It is also possible to connect the plug 3 to the insufflation tube 2 by means of a connecting member 4 so that it will not be lost when the plug is removed.

Furthermore, in order to lower the center of gravity of the top and increase its mass, it is desirable that the blowing tube 2 and/or the stopper 3 be made of a material with a high specific gravity, such as hard synthetic resin or metal.

Effects of this invention As mentioned above, the top according to this invention includes a top body made of a soft synthetic resin bag, and a blowing tube with a stopper that protrudes from the top body and is used to supply fluid into the top body. Since the stopper inserted into the blowing tube serves as the grounding axis, when not in use, the fluid can be extracted from the main body and folded compactly, making it convenient to carry or store.
Even if the wearer falls down, the grounding shaft will not pierce the body, so the top will not cause serious injury, and the top can be safely carried and played with.
