Description

TECHNICAL FIELD

[0001] The present application relates to the construction of a shuttlecock, in particular the artificial feather of a shuttlecock. BACKGROUND

[0002] The structure of a shuttlecock can be basically divided into two parts, a "head" and "feathers". The head is a cylinder with a semi-spherical front end, which is the part that contacts the racket face of a racket. The racket face is made of a net formed by a special string arranged in a crisscross pattern. The feathers are evenly inserted into the tail end of the head and arranged in a similar conical structure. The common specification of a shuttlecock uses 16 feathers.

[0003] According to the classification of the materials used to make a shuttlecock, it can be basically divided into two types, natural materials and artificial materials. The shuttlecock made of natural materials is relatively more expensive than the shuttlecock made of artificial materials. Therefore, the shuttlecock made of natural feathers is mostly used for competitions, while the shuttlecock made of artificial materials is used as a practice ball for beginners.

[0004] Natural feathers, such as goose or duck feathers, are usually used. The collection, sorting, and processing of natural feathers are not easy, which makes them relatively expensive. In a competition, the stability of a shuttlecock in flight is maintained by replacing the shuttlecock immediately when the feathers are slightly damaged, which affects the flight trajectory. During a high-intensity competition, the consumption of shuttlecocks is high.

[0005] In the approved Chinese Taiwan invention patent "Artificial feather for shuttlecock, and shuttlecock" (Certificate No. TW I713740), the feather part of the artificial feather is made of, for example, non-woven fabric or resin. In the case of using non-woven fabric, a reinforced film is formed on the surface to prevent the fibers of the non-woven fabric from unraveling when the shuttlecock is hit. The reinforced film can be formed by applying resin.

[0006] In the approved Chinese Taiwan invention patent "Shuttlecock and its feather shaft" (Certificate No. TW I636815), the shuttlecock includes a plurality of feather pieces, a head, and a plurality of feather shafts. The feather shaft includes a shaft body having a feather piece end and a head end, the shaft body is made of plastic material, and one of the plurality of feather pieces is joined to the feather piece end. The shaft body includes a hollow tube body having an upper top surface and a lower top surface, a containing channel in the hollow tube body, and a pair of side wings connected to the two opposite sides of the hollow tube body, the side wings are in a sheet structure and are connected to the two opposite sides of the hollow tube body, the pair of side wings can stably connect each feather piece thereto, and a foamed material is filled in the containing channel. The foamed material filled in the interior of the shaft body imitates the porous structure of natural feathers, which makes the feather shaft light in weight and low in density, and has impact resistance and toughness.
