(57) A shuttlecock comprising a cap portion and a plastics skirt in the form of a truncated
conical lattice structure having main stems interconnected by ribs with further intermediate
stems located between the main stems, the lattice structure in the vicinity of the
wide end of the skirt being convoluted with the flutings extending at an acute angle,
preferably 45° to the longitudinal axis of the shuttlecock, and being so orientated
as to make the shuttlecock spin and otherwise behave as a feathered shuttlecock.
Preferably, slots or slits are provided in the skirt at its wide end and the convolutions
extend approximately from one end of one slot to the opposite end of an adjacent slot.
The convolutions are formed by deforming the skirt material inwardly and this has
the effect of slightly widening the slits in the shuttlecock.
Although preferred, the ribs, at least at the wide end of the skirt, need not be provided,
and could be replaced by plastics flumes.
