からである。2. Description of the Related Art With the increase in the number of badminton athletes, it is likely that shuttlecocks using waterfowl will become difficult to obtain in the future. Further, since the waterfowl feathers are not constant in quality and inferior in productivity, there is a demand for an inexpensive shuttlecock made of an artificial material such as synthetic resin having high mass productivity. What has been widely known as a conventional shuttlecock made of an artificial material such as a synthetic resin has an integrally formed annular blade. This shuttlecock made of artificial material has a so-called skirt integrally connected, and when it is hit by a racket, it sometimes deforms irregularly so that it partially bends, and sometimes it makes a meandering flight. This is because, unlike a shuttlecock with natural blades, each blade cannot be independently deformed so as to freely squeeze to the axial side of the head at the time of its impact and quickly restore again.

It was proposed as No. 9086 and No. 59-150475. In these shuttlecocks, at least the shaft part of the blade is made of synthetic resin material, and a large number of independent synthetic resin blades are planted in the striking head to obtain the feel and flight characteristics of natural blades. Was to be. However, compared to natural blades, artificial blades such as synthetic resin materials have a higher density than natural blades, and if you try to make blades with the same strength as natural blades, the weight as a whole becomes large, It had the drawback of not being suitable for sports equipment. Then, the actual development Sho 59-1504
The shuttlecock of No. 75 has proposed that the shaft portion has a tubular structure to maintain the lightness of the blades and increase the strength of each blade.

It was difficult to make it close to the feathers of. This is because the valve portion that affects most of the flight characteristics of the blade is the same as that of the conventional synthetic resin. Therefore, there is a problem in the lightness of the blade as a whole and the resilience upon impact. Therefore, the present invention has the following configuration in order to solve the above problems.

つ、天然羽根同様に軽量化することが可能となる。The shuttlecock of the present invention comprises at least a part of the blade shaft 3 of the independent blade 1 made of synthetic material such as synthetic resin and the blade valves 4 integrally extended on both sides thereof. Since it is formed in a hollow shape, the rigidity of the blade valve 4 is particularly strengthened, the restoring force of the blade 1 immediately after striking is increased, the flight characteristics equivalent to those of a natural blade can be obtained, and the weight of the blade 1 can be reduced. . That is, in the shuttlecock, independent blades once hit by the hitting of the racket close to the axial side of the hitting head 2, and when the shuttlecock is restored, a braking action is caused to perform an ideal flight. The natural blade has a great restoring force not only on the blade axis but also on the blade valve itself, but in the shuttlecock made of an artificial material such as a synthetic resin of the present invention, at least a part of the blade valve 4 is hollow. Therefore, the same restoring force as natural feathers can be expected. At the same time, it is possible to reduce the weight as well as the natural blade while maintaining the restoring force.

In the case where the above is provided, the restoring force can be further enhanced.
At the same time, the strength of the shuttlecock can be kept strong. Next, in the blade shaft 3 and the blade valve 4 provided with a large number of thin tube portions 9, the flexibility and the restoring property are further improved. Furthermore, in the case where a plurality of branch portions 6 extending from the blade shaft 3 into the blade valve 4 are provided and the branch portions 6 are formed hollow, the resilience and weight reduction of the blade valve 4 are further improved. Can be improved.
Further, in the case where the hollow outer edge portion 7 is formed on the outer peripheral edge of the blade valve 4, the strength of the outer periphery of the blade 1 is increased, and the shuttlecock has high durability.
