Abstract: The invention relates to a shuttlecock comprising a conical crown (2) and a base (3) for hitting. In order to modify the flying characteristics, a preferably toroidal ring (4) which is made of an elastic material is mounted on the shuttlecock (1) in a biased state so as to surround the crown (2). Said ring is preferably retained in a fixed position by means of the rear limit of the base (3) and the forward zone (21) of the crown (2), rear and forward being in relation to the flying direction. The forward zone (21) of the crown (2) can be formed by stems (21), for example. Alternatively, several rings can be provided. The invention allows the flying characteristics of the birdie to be modified in a particularly simple and fast manner. The birdie can be made to fly in a more stable fashion by means of the weight of the ring, for example, resulting in greater speeds and ranges.

Abstract: A shuttlecock to be struck by a racquet has a shaped base and a number of separate flexible tail portions secured to the base. The base also has a piston element therein, so as to form a shuttlecock that has a varying movement or erratic flight performance when struck. A game is played by hitting the shuttlecock through a marked-off area called a flyzone. Scoring of a game or sets is determined by the elapsed time the shuttlecock is hit back and forth by at least two players through field goals formed at opposite ends of the marked-off area.

Abstract: A play device designed to be struck by various parts of the human anatomy, or with rackets or paddles, depending on the size of the play device. The tail portion of the play device, consists of a curved bell shaped structure, constructed from a suitable molded plastic or a composite of materials; which allows for a strong, flexible, lightweight tail. The length of the tail portion forms a parabolic curve, which increases the compression strength of the tail, as well as increases the drag the tail lends to the device while in flight. The tail portion of the device is connected to a substantially round striking(head)portion. The proportions and weight characteristics enable the shuttle to quickly recover to a head first stable flight pattern, thereby enabling a player to repeatedly strike the device, with the intention of sustaining it's flight.
