Technical Field

The invention relates to a badminton, in particular to a plastic feather piece of a badminton.

Background

The existing badminton is mainly divided into two types, namely natural feather manufacturing and plastic material manufacturing; due to the characteristics of the natural feather, the badminton manufactured by using the natural feather has better airflow guiding effect and better flying characteristic when flying; however, in recent years, the supply of natural feather is sharply reduced, and the obtained natural feather needs to be subjected to steps such as screening, straightening, trimming and gluing to be used as a material for manufacturing the badminton, so that the processing cost is high, and the natural badminton is easy to break the feather or break the feather surface due to slapping and is easy to scrap.

The badminton made of plastic materials mostly uses the soft ball frame made of nylon to replace natural feathers, has a tough structure, and can reduce the breakage of the badminton, however, because the skirt wings of the badminton made of plastic materials are connected into a whole, the air current effect like the natural badminton cannot be generated, and the hitting touch feeling provided is not the same as that of the badminton made of natural feathers.

However, the conventional artificial feather mainly has a straight rod and two wings, and when the artificial feather is inserted into the head, a straight cone-shaped skirt unit is usually formed, which easily causes wind resistance, and cannot guide airflow like natural feather, and thus further improvement is needed.

The plastic feather piece of the badminton is integrally formed by plastic materials and comprises a feather shaft and two feather pieces, wherein the feather shaft comprises an insertion end and a top end, and defines a left side, a right side, an outer side, an inner side, a plane vertical to the insertion end and a vertical shaft vertical to the plane; the two feather pieces are respectively formed on the left side and the right side of the feather shaft and are adjacent to the top end, a plurality of air guide flow holes are formed in each feather piece and are arranged at intervals, the feather shaft extends upwards and outwards in an arched manner gradually from the insertion end, so that a space deflection angle is formed between the top end and the insertion end and the vertical axis Z, the deflection towards the outer side from the top end of the feather shaft to the insertion end relative to the vertical axis forms a first angle, the first angle is larger than 0 degree and smaller than or equal to 30 degrees, a left deflection angle and a right deflection angle are formed between the top end of the feather shaft and the insertion end relative to the vertical axis towards the left side and the right side, and the left deflection angle and the right deflection angle are within a range of +/-30 degrees and comprise +/-30 degrees.

The two feathers in the plastic feather of the invention are symmetrical along the left and right of the center of the feather axis, the two feathers can have the same area size, or the two feathers are asymmetrical along the left and right of the center of the feather axis, wherein the area of one feather is larger than that of the other feather.

The outer diameter of the shaft is gradually reduced from the top of the insertion head to the top end, and the shaft protrudes out of the surface of the vane at the inner side and the outer side.

The two vanes of the present invention extend laterally a distance less than the longitudinally extending distance and the laterally extending end points of the two vanes are located proximate the tip.

The air guide holes on the vanes are arranged at intervals along the axial direction of the shaft, and the air guide holes extend transversely.

The transverse edges of the air flow holes on each vane of the invention are inclined upwards towards the direction far away from the vane shaft.
