Abstract
A game system having a net and a shuttlecock for playing a game involving hitting the shuttlecock back-and-forth between players located on opposite sides of the net. The net is supported above a ground surface and has an opening formed therethrough to provide passage of the shuttlecock through the net when hit by one or more players located on opposite sides of the net. The shuttlecock has a plurality of flexible feather fins that are specifically configured and arranged to provide airspeed braking of the shuttlecock when in flight to control the speed and the distance that the shuttlecock may be hit.
Claims9
A shuttlecock, comprising:
- a nose cone having a striking end, an attachment end, and a nose cone axis extending between the striking and attachment ends;
- a plurality of flexible feather fins attached to and extending from the attachment end;
- wherein the plurality of flexible feather fins are arranged and configured to impart a spin in the shuttlecock about the nose cone axis during flight of the shuttlecock through air when struck on the striking end;
- wherein the plurality of flexible feather fins are further arranged and configured to bend outwardly in a direction away from the nose cone axis by centrifugal forces acting on the flexible feather fins created by the spin of the shuttlecock, and wherein the bending of the plurality of flexible feather fins causes an airspeed braking on the shuttlecock;
- wherein each flexible feather fin has a shaft, an inner vane attached to the shaft, and an outer vane attached to the shaft, the inner and outer vanes each having a convex curvature;
- wherein each flexible feather fin is arranged such that the convex curvature of the inner vane and of the outer vane are facing inwardly toward the nose cone axis and that the attachment points of the inner vane and of the outer vane with the shaft are at a 90-degree angle relative to a radian line extending from the nose cone axis through a longitudinal axis of the shaft;
- and
- wherein each feather fin is arranged such that the outer vane is disposed on an inward side of the inner vane of an immediately adjacent feather fin in an overlapping arrangement with a leading edge of the outer vane facing in an outward direction away from the nose cone axis, and wherein the inward side of the inner vane is a surface of the inner vane that faces toward the nose cone axis.

A shuttlecock, comprising:
- a nose cone having a striking end, an attachment end, and a nose cone axis extending between the striking and attachment ends;
- a plurality of flexible feather fins attached to and extending from the attachment end such that the flexible feather fins are equally circumferentially spaced around the attachment end and at the same radial distance from the nose cone axis, each feather fin has a total length of between 10 and 18 cm as measured from tip to tip before attachment to the attachment end, each feather fin has a shaft, an inner vane attached to the shaft, and an outer vane attached to the shaft, and the inner and outer vanes each having a convex curvature;
- wherein the plurality of feather fins are arranged and configured to impart a spin in the shuttlecock about the nose cone axis during flight of the shuttlecock through air when struck on the striking end;
- wherein the plurality of feather fins are further arranged and configured to bend outwardly in a direction away from the nose cone axis by centrifugal forces acting on the feather fins created by the spin of the shuttlecock, and wherein the bending of the plurality of feather fins causes an airspeed braking on the shuttlecock;
- wherein each feather fin is arranged such that the convex curvature of the inner vane and of the outer vane are facing inwardly toward the nose cone axis and that the attachment points of the inner vane and of the outer vane with the shaft are at a 90-degree angle relative to a radian line extending from the nose cone axis through a longitudinal axis of the shaft;
- and
- wherein each feather fin is arranged such that the outer vane is disposed on an inward side of the inner vane of an immediately adjacent feather fin in an overlapping arrangement with a leading edge of the outer vane facing in an outward direction away from the nose cone axis, and wherein the inward side of the inner vane is a surface of the inner vane that faces toward the nose cone axis.

A game, comprising:
- a net, the net supported above a ground surface in a vertical orientation, the net having an opening formed completely therethrough to allow an object to pass through the opening when hit by one or more players located on opposite sides of the net, the opening having a periphery and the net surrounding the periphery of the opening;
- and
- a shuttlecock, the shuttlecock comprising:
- a nose cone having a striking end, an attachment end, and a nose cone axis extending between the striking and attachment ends
- a plurality of flexible feather fins attached to and extending from the attachment end;

- wherein the flexible feather fins are further arranged and configured to bend outwardly in a direction away from the nose cone axis by centrifugal forces acting on the feather fins created by the spin of the shuttlecock, and wherein the bending of the flexible feather fins causes an airspeed braking on the shuttlecock;
- each feather fin has a shaft, an inner vane attached to the shaft, and an outer vane attached to the shaft, the inner and outer vanes each having a convex curvature;
- each feather fin is arranged such that the convex curvature of the inner vane and of the outer vane are facing inwardly and that the attachment points of the inner vane and of the outer vane with the shaft are at a 90-degree angle relative to a radian line extending from the nose cone axis through a longitudinal axis of the shaft;
- and
- wherein each feather fin is arranged such that the outer vane is disposed on an inward side of the inner vane of an immediately adjacent feather fin in an overlapping arrangement with a leading edge of the outer vane facing in an outward direction away from the nose cone axis, and wherein the inward side of the inner vane is a surface of the inner vane that faces toward the nose cone axis.
