Title:
シャトルコック用人工羽根およびバドミントン用シャトルコック
Document Type and Number:
Japanese Patent JP5198582
Kind Code:
B2
Abstract:
An artificial feather for a shuttlecock, and a badminton shuttlecock which have flight performance and durability equal to those of a shuttlecock employing waterfowl feathers can be obtained. An artificial feather (3) for a shuttlecock includes a feather portion (5) and a shaft (a fixed shaft portion 10) connected to the feather portion (5). The feather portion (5) includes a foam layer (92) and a shaft fixing layer (91) bonded to the foam layer (92) with the fixed shaft portion (10) sandwiched therebetween. The foam layer (92) and the shaft fixing layer (91) have an identical planar shape. With this configuration, by using the foam layer (92) as the feather portion (5), an increase in the mass of the feather portion (5) is suppressed and rigidity is improved (i.e., deformation due to hitting is suppressed), and thereby a change in the shape of the artificial feather (3) for the shuttlecock can be suppressed.
