  • Patent number: 11944885
    Abstract: The present invention relates to a shuttlecock generally including a striking part and an aerodynamic part. The shuttlecock includes: a base to serve as striking element for the striking part of shuttlecock, a stems part formed by a plurality of stems to provide support to the aerodynamic part, the stems being connected or connectable with the base, and a sheeting part formed by a sheeting for forming of an aerodynamic member of the aerodynamic part attached or attachable to the stems. The stems part substantially has a shape of a pyramidal stems frustum, the base of the frustum preferably conforming to the open end of the aerodynamic part. The sheeting part, while attached to the stems, substantially has a shape of a pyramidal sheeting frustum. The edges of the pyramidal sheeting frustum are defined by the edges of the pyramidal stems frustum at an overlapping part of the sheeting part with the stems part.
