Definitions

  • the invention relates to a shuttlecock with a crown having a substantially conical shape, wherein the crown is connected to a striking cap in the region of the narrow crown end.
  • WO 2005/000428 A1 includes a number of terminology definitions which can analogously be adopted for the present invention.
  • the conventional subject matter disclosed therein is a shuttlecock with a conical crown and a striking cap arranged on the crown. At least one removable ring is arranged on the crown which can be used to alter the flight characteristics.
  • the crown itself has a straight conical surface envelope.
  • the shuttlecock should also retain to the greatest possible extent its dimensional stability even when damaged.
  • a shuttlecock which has a conically shaped crown that is connected with a striking cap.
  • the surface envelope of the crown is here provided with an inwardly curved radius in the region of the crown opening.
  • the surface envelope which is inwardly curved in the end region of the crown opening with a radius, reduces the air resistance of the shuttlecock, meaning that the shuttlecock experiences less wind resistance along its flight path.
  • This shape of the surface envelope with an inwardly curved radius in the region of the crown opening advantageously also reduces the deviations of the shuttlecock during flight from its intended flight path in crosswind.
  • the shape of the shuttlecock according to the invention also points the shuttlecock much better into the wind on its flight path than a smooth conical shuttlecock with a straight surface envelope.
  • the shape of the shuttlecock according to the invention keeps the shuttlecock on its path and extends the range, because the shuttlecock does not rotate in the air along its flight path about its own axis, i.e., around itself.
  • the cross rib arranged at the crown opening has a wavelike shape.
  • the end segments at the crown opening have indentations and protrusions. This also improves the accuracy of the flight path and of the flight trajectory, and the shuttlecock also becomes dimensionally more stable. Consequently, even if continuous use of the shuttlecock causes partially vertically extending cracks, its flight characteristics remain superb.
  • the shuttlecock does not rotate about its own axis during flight.
  • either the wave maximum is located at a longitudinal rib and the wave minimum is located centrally between the longitudinal ribs, or vice a versa.
  • the flight characteristics can be further improved by arranging the segment ribs in the end segments in the region of the crown opening with mutually different spacing.
  • the flight stability and range can be further improved by implementing the transition between the striking cap and the press ring without a step.
  • FIG. 1 a shuttlecock according to the invention with an inwardly curved radius of the surface envelope in the region of the crown opening,
  • FIG. 2 a top view on the wavelike crown opening of the shuttlecock
  • FIG. 2A the wavelike crown opening of the shuttlecock with a wave maximum at the longitudinal ribs
  • FIG. 2B the wavelike crown opening of the shuttlecock with a wave minimum at the longitudinal ribs
  • FIG. 3 a shuttlecock with a step-less transition of the striking cap and installed wind ring
  • FIG. 4 a cross-sectional view of FIG. 3 .
  • the shuttlecock is composed of a crown 1 and a striking cap 9 , wherein at least one press ring 10 is arranged between the crown 1 and the striking cap 9 .
  • the press ring 10 protrudes from the striking cap 9 , so that an edge is formed between the press ring 10 and the striking cap 9 .
  • the crown 1 has in the region of the crown opening 3 an end region 4 with an inwardly curved radius. This radius clearly moves away from the imaginary extension of the surface envelope of the lower region of the crown 1 facing the striking cap 9 . This produces the spacing X indicated in FIG. 1 .
  • the crown itself is composed of longitudinal ribs 5 and transverse ribs 6 , which form segments 7 .
  • the segments 7 have segment ribs 8 .
  • the segment ribs 8 have different spacings from one another in the end segments 7 a proximate to the crown opening 3 .
  • the separation between the segment ribs in the end segments 7 a can be very narrow on one side and somewhat wider on the other side.
  • the transverse rib 6 a arranged at the crown opening 3 has a wavelike shape.
  • the wave maximum is located on a longitudinal rib 5
  • the wave minimum is located centrally between the longitudinal ribs 5 .
  • FIG. 2B shows a different embodiment where the wave minimum is located at a longitudinal rib 5 .
  • the shape of the waveform can also be modified in that not rounded portions, but pointed tips are realized at the wave maximum and at the wave minimum.
  • the end segments 7 a have indentations due to the wavelike shape of the transverse ribs 6 a.
  • Releasable rings 11 can be arranged between the crown 1 and the striking cap 9 for increasing the weight of the shuttlecock and changing the flight characteristics, as illustrated in the Figure and in FIG. 4 .
  • a ring arranged in this fashion is then held at a fixed location under pretension by, on one hand, the conical surface envelope of the crown 1 and, on the other hand, by a rear boundary wall of the striking cap 9 .
  • FIG. 3 shows a different embodiment of the shuttlecock, wherein the transition between the striking cap 9 and the press ring 10 is implemented without a step. This arrangement further reduces the air resistance of the shuttlecock in flight.
  • the press ring 10 is recessed in the striking cap 9 and flush with the striking cap 9 .
  • the cross-sectional view according to FIG. 4 illustrates anchoring of the crown 1 in the striking cap 9 .
