A modified shuttlecock, suitable for children, beginners and old people, has, in place of the usual feathers, a parachute membrane 6 which is made to open by the wind resistance to slow the "shuttlecock" down and when the speed has dropped, is closed by means of a tension spring 5 connected between the middle of the parachute membrane 6 and a base 2 upon which the pneumatic nose portion 1 is fixed. The edges of the parachute membrane 6 are attached by a series of elongated members 3 to the base 2, the members 3 being pivoted to the base 2 so that they can spread apart and close together again as the parachute membrane opens and closes. The parachute membrane 6 and the nose portion 1 are both painted in sectors in different fluorescent colours. <IMAGE> |
