Abstract
The invention describes a shuttlecock with a conically shaped crown (1), wherein, in contrast to the circumferential surface which, in the case of known shuttlecocks, has a straight conical profile, the crown (1) is designed in the region of the crown opening (3) with an end region (4) having an inwardly curved radius.
Description
- This application is a National Phase Patent Application of International Patent Application Number PCT/EP2008/061061, filed on Aug. 25, 2008, which claims priority of German
Patent Application Number 10 2007 041 169.5, filed on Aug. 24, 2007. - 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.
- It is an object of the invention to provide a shuttlecock which has improved flight characteristics compared to conventional shuttlecocks and which ensures, more particularly, a stable flight path and a greater range.
- The shuttlecock should also retain to the greatest possible extent its dimensional stability even when damaged.
- The object is solved with the invention by the features in the characterizing portion of
claim 1. Advantageous embodiments of the invention are recited in the dependent claims. - According to the invention, a shuttlecock is provided which has a conically shaped crown that is connected with a striking cap. Unlike the otherwise straight conical envelope in the end region of conventional shuttlecocks, 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. At the same time, 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.
- According to an advantageous embodiment of the invention, the cross rib arranged at the crown opening has a wavelike shape. As a result, 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.
- By only providing the transverse rib disposed at the crown opening with a wavelike shape, the shuttlecock does not rotate about its own axis during flight.
- Advantageously, with this embodiment of the shuttlecock, 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.
- The invention will now be described in more detail with reference to exemplary embodiments which are at least partially illustrated in the drawings. It is shown in:
-
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, and -
FIG. 4 a cross-sectional view ofFIG. 3 . - As seen in
FIG. 1 , the shuttlecock is composed of acrown 1 and astriking cap 9, wherein at least onepress ring 10 is arranged between thecrown 1 and thestriking cap 9. Thepress ring 10 protrudes from thestriking cap 9, so that an edge is formed between thepress ring 10 and thestriking cap 9. Unlike conventional shuttlecocks with a straight conical surface envelope, thecrown 1 has in the region of the crown opening 3 anend 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 thecrown 1 facing thestriking cap 9. This produces the spacing X indicated inFIG. 1 . The crown itself is composed oflongitudinal ribs 5 andtransverse ribs 6, which formsegments 7. - The
segments 7 havesegment ribs 8. Thesegment ribs 8 have different spacings from one another in theend segments 7 a proximate to the crown opening 3. For example, the separation between the segment ribs in theend segments 7 a can be very narrow on one side and somewhat wider on the other side. - As seen from
FIG. 2 , thetransverse rib 6 a arranged at the crown opening 3 has a wavelike shape. Both in this embodiment and in the embodiment illustrated inFIG. 2A , the wave maximum is located on alongitudinal rib 5, while the wave minimum is located centrally between thelongitudinal ribs 5.FIG. 2B shows a different embodiment where the wave minimum is located at alongitudinal 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. Theend segments 7 a have indentations due to the wavelike shape of thetransverse ribs 6 a. -
Releasable rings 11 can be arranged between thecrown 1 and thestriking cap 9 for increasing the weight of the shuttlecock and changing the flight characteristics, as illustrated in the Figure and inFIG. 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 thecrown 1 and, on the other hand, by a rear boundary wall of thestriking cap 9. -
FIG. 3 shows a different embodiment of the shuttlecock, wherein the transition between thestriking cap 9 and thepress ring 10 is implemented without a step. This arrangement further reduces the air resistance of the shuttlecock in flight. In this modified embodiment, thepress ring 10 is recessed in thestriking cap 9 and flush with thestriking cap 9. - The cross-sectional view according to
FIG. 4 illustrates anchoring of thecrown 1 in thestriking cap 9. - The invention is not limited to the illustrated embodiments. Additional modified embodiments can be realized by modifying the aforementioned elements and features, without departing from the spirit of the invention.
