Artificial feathers and shuttlecocks for badminton

Abstract

The special artificial feather for badminton of the present invention comprises pinna (11) and feather stem (12), is characterized in that, described feather stem (12) comprises two or more than two independent rods, and the rods are connected to each other. juxtaposed against each other. Two, three or four rods of different lengths can be used to make feather stems, the longest one is the main rod (121), the second longest one is the auxiliary rod (122), and the slightly shorter one is the ejector rod (123) . When this artificial feather is made into a shuttlecock, the upper end of the auxiliary pole (122) can be wound by the vane positioning coil (3), thereby being fixed together with the main pole (121). The upper end of the push rod (123) can be covered and wound by the waist coil (2) of the shuttlecock, so that the upper end of the push rod (123) and the main rod (121) and the auxiliary rod (122) are fixed together, and the push rod The upper end of (123) can withstand waist coil (2), prevents it from sliding down. The present invention also relates to a shuttlecock made of the artificial feather.

Description

technical field [0001] The invention relates to a special artificial feather for shuttlecock, and also relates to a shuttlecock made of the artificial feather. Background technique [0002] Adopting artificial material to replace natural goose and duck feather to make shuttlecock is an ideal of industry circle and badminton sports circle. Because the playing resistance of the goose and duck feather shuttlecock is too poor, players frequently change the ball, and the cost of playing is greatly increased; meanwhile, the production process of the goose and duck feather shuttlecock is complicated, and the cost of the material itself is also relatively high. However, the technical difficulties hidden in this material replacement are by no means imagined by ordinary people. The industry has carried out relevant research work for more than 20 years, but so far, there is no shuttlecock made of artificial materials instead of goose and duck feathers, which has reached the level of h...

AI Technical Summary

Problems solved by technology

[0014] 1. Due to the characteristics of the pultrusion process itself, this ultra-light and high-strength fiber-reinforced resin composite material rod cannot be made into a certain taper - the taper shape can be made into a large end and a small end by grinding, but it will seriously reduce its strength

Therefore, this rod cannot be made too thick

If it is too thick, not only the pinna area of ​​the feather will be overweight, but also the feather stalk will decrease its elasticity due to too good rigidity (hardness), so it is easy to be broken

[0015] Second, more importantly, it is difficult for fiber reinforced resin composite rods to balance rigidity and toughness

That is to say, when a slightly thicker bar is used, the rigidity is very good, but the toughness is slightly lacking, so that the feather stalk is easy to break when it is hit directly.

Conversely, when a slightly thinner bar is used, the toughness is better, but the rigidity is not enough, resulting in a sudden change in wind resistance of the badminton, which seriously affects the flight performance

[0016] 3. Due to the thinner stem, the fastness of the connection between the stem and the ball head is not enough when the shuttlecock is made

[0019] Further tests found that there are still some problems affecting the performance and durability of this double-rod shuttlecock: first, the rigidity of the artificial feather feather area is still slightly insufficient; Basically the same, resulting in the waist coil of the shuttlecock is easy to slip when it is made into a whole ball, which affects the performance and durability
