Description

Badminton and its hair rod

The present invention relates to a hair rod, and more particularly to a hair rod for use in a shuttlecock.

The badminton competition is a common and popular ball game, and the hitter fights badminton as a competition. The traditional badminton structure is made of natural feathers combined with the ball head. The natural feathers are mostly goose feathers or duck feathers.

However, it has become increasingly difficult to obtain natural feathers, and the screening of feathers has been quite troublesome. Therefore, badminton made of artificial hair pieces is also available for users to choose. However, most of the current artificial badmintons are made of soft flakes made of nylon instead of natural feathers. Their impact resistance and the speed of hitting are not as good as traditional natural feathers.

According to an embodiment of the invention, the hollow tubular body receiving passage has a substantially elliptical cross-sectional shape.

According to an embodiment of the invention, the hollow tubular body wall has a thickness of between 0.1 mm and 0.25 mm, and the pair of side wings has a thickness of between 0.2 mm and 0.5 mm.

According to an embodiment of the invention, the pruning width of the hair rod of the present invention is equal in width and the width is between 1 mm and 3 mm.

According to an embodiment of the invention, the pruning width of the hair shaft of the present invention is non-equal width, which is gradually narrowed from the end of the ball to the end of the blade.

According to an embodiment of the invention, the pruning width of the hair shaft of the present invention is gradually narrowed from 2 mm to 1 mm from the end of the ball to the end of the blade.

According to an embodiment of the invention, the length of the hair shaft of the invention is 75 ± 5 mm.

According to an embodiment of the present invention, the hollow tubular body has an upper top surface and a lower top surface, wherein the upper top surface and the lower top surface respectively face opposite directions; the vertical distance from the top surface to the opposite side wing at the ball end end It is substantially equal to the vertical distance from the top surface to the opposite side of the ball end, both 0.5 mm to 2 mm.

According to an embodiment of the invention, the maximum vertical distance connecting the horizontal end of the blade end to the ball end to the top surface of the hollow body is between 0 and 4 mm.

According to an embodiment of the invention, wherein the vertical distance from the top surface to the opposite side wing at the midpoint is substantially twice the vertical distance from the top surface to the opposite side wing at the midpoint.

According to an embodiment of the invention, the rod system is made of a composite material and a plastic material.
