| 20100311526 | SHUTTLECOCK - A shuttlecock including a cap and a skirt part whereto an air passage hole is formed, wherein a rib is provided to the skirt part, adjacent to a rear end of the air passage hole in a generatrix direction of the skirt part, the rib having a shape wherein air pressure difference is generated between an air flow passing through the air passage hole to flow on an inside of the rib and an air flow not passing through the air passage hole but to flow on an outside of the rib, and an aerodynamic force directed from the inside of the rib to the outside is generated. | 12-09-2010 |
| 20120040786 | Shuttlecock - A shuttlecock preferably includes a tail, a shuttle housing and an impact head. The tail includes at least three tail sections which are attached to each other and retained by a tail base. The shuttle housing preferably includes a first housing half, a second housing half and an electrical circuit. The electrical circuit preferably includes a circuit board, an vibration sensor, at least one light emitting device and a sound emitting device. The circuit board includes an electrical controller and a battery. The vibration sensor detects that the shuttlecock is in motion and sends an electrical signal to the electrical controller, which activates the at least one light emitting device and/or the sound emitting device, until the shuttlecock is no longer in motion. The impact head preferably includes a plurality head discs, a plurality of buffer discs and a disc strap. | 02-16-2012 |
| 473580000 | Having independent feathers or vanes | 7 |
| 20110034277 | SHUTTLECOCK - The invention describes a shuttlecock with a conically shaped crown ( | 02-10-2011 |
| 20120157248 | SHUTTLECOCK - A shuttlecock includes a ball head, a pinnae supporter and some pinnae. The pinnae supporter and the ball head can be made integrally or connected after being made respectively. The pinnae are inserted into the tubes of the pinnae supporter. | 06-21-2012 |
| 20130210564 | ARTIFICIAL FEATHER FOR SHUTTLECOCK AND SHUTTLECOCK - A plurality of artificial feathers for a shuttlecock, when a hemispherical base portion of the shuttlecock is set on a lower side, the artificial feathers being embedded in an annular ring form on a peripheral border of a circular top end face of the base portion, the artificial feathers for a shuttlecock each including a vane portion in a thin film form, corresponding to a vane, the vane portion being provided with a reinforcement coating made of applied resin, and a rachis portion in a bar form extending integrally and continuously from an upper tip end to a lower distal end, corresponding to a rachis, to imitate a natural feather, the rachis portion being fixed to the vane portion at a vane support portion, having the vane support portion set as an area that is fixed to the vane portion along the tip end to a bottom end of the vane portion, and having a calamus portion set as an area that protrudes to a lower side of the vane portion and spans from a bottom end of the vane support portion to the distal end, to correspond to a calamus of the natural feather. | 08-15-2013 |
| 20130225339 | ARTIFICIAL FEATHER FOR SHUTTLECOCK, SHUTTLECOCK, AND METHOD OF MANUFACTURING ARTIFICIAL FEATHER FOR SHUTTLECOCK - An artificial feather for a shuttlecock including a vane portion in a thin film form, corresponding to a vane, and a rachis portion in a bar form extending integrally and continuously from an upper tip end to a lower distal end, corresponding to a rachis, to imitate a natural feather, the vane portion being made of thermoplastic resin having interconnecting bubbles therein, and having low specific gravity and low elasticity relative to the rachis portion, the rachis portion being made of thermoplastic resin being fixed to the vane portion at a vane support portion, having the vane support portion set as an area that is fixed to the vane portion along the tip end to a bottom end of the vane portion, and having a calamus portion set as an area that protrudes to a lower side of the vane portion and spans from a bottom end of the vane support portion to the distal end, to correspond to a calamus of the natural feather. | 08-29-2013 |
| 20140121046 | Shuttlecock - A shuttlecock includes a ball head, a pinnae supporter and some pinnae. The pinnae supporter and the ball head can be made integrally or connected after being made respectively. The pinnae are inserted into the tubes of the pinnae supporter. | 05-01-2014 |
| 20140155201 | ARTIFICIAL FEATHER FOR SHUTTLECOCK, SHUTTLECOCK, AND METHOD OF MANUFACTURING ARTIFICIAL FEATHER FOR SHUTTLECOCK - An artificial feather for a shuttlecock including: a sheet form vane portion; and a rachis portion supporting the vane portion, the rachis portion being made of resin including glass fiber and carbon nanotube. | 06-05-2014 |
| 20140335980 | Shuttlecock and Manufacturing Method Thereof - A shuttlecock includes: a set of feather units, a shuttlecock head, and a connecting arrangement which including a feather planting arrangement. The feather planting arrangement includes a set of feather planting members of the same number as the number of the feather units, each feather planting member has a feather planting end portion and an insertion end portion, a shaft member of each feather unit is inserted in the feather planting end portion while the insertion end portion of each feather planting member is inserted in the shuttlecock head. Further disclosed is a method of manufacturing the shuttlecock. | 11-13-2014 |
