DESCRIPTION OF THE PREFERRED EMBODIMENTS

(8) The following description is provided to enable any person skilled in the art to make and use the invention and sets forth the best modes contemplated by the inventor of carrying out his invention. Various modifications, however, will remain readily apparent to those skilled in the art, since the generic principles of the present invention have been defined herein specifically to provide for an improved shuttlecock assembly.

(9) The improved shuttlecock of the present invention may be used in any type of a racquet sport game, for example, in the same manner as described in the sports game set forth in the '353 patent.

(10) Turning now to the drawings, FIGS. 1-3 illustrate a preferred embodiment of a shuttlecock 10 of the present invention. The shuttlecock 10 includes a core housing 12 having a separable nose cone 14 secured over the core housing, as by means of an adhesive or the like. The core housing 12 (see FIG. 3) is comprised of a substantially solid base, which may be one piece or multi-component, having a larger upper portion 16 and a lower half round 18 secured, as by a pin or other securing means, in the larger upper portion. A plurality of tail fins 22 are releasably secured, as by pins or screws 22 to openings 27 formed in the upper portion 16. In the preferred embodiment of the invention the shuttlecock assembly 10 includes five (5) tail fins 20.

(11) The nose cone 14 includes fluted inner and outer surfaces and a hollow inner chamber 24 having a waffle impact zone cushion area or portion 25 formed on the lower interior surface thereof. As best shown in FIG. 3 the hollow inner chamber 24 is sized and dimensioned to snugly hold the core housing 12 when inserted therein, with the lower half round 18 rests against the waffle impact zone cushion area 25 when the shuttlecock is assembled.

(12) The shuttlecock may be of any desired size with its components made from any desired materials. For example, the core housing or base 12 may be made from plastic or a hardened rubber, while the nose cone 14 is preferably made from rubber or another resilient material. And, the tail fins 20 are preferably made from a resilient plastic.

(13) As best shown in FIGS. 3-5, the tail fins 20 include a base or lower portion 26 having one or more openings 28 formed therein through which the securing elements 22 pass, and outer or upper curved window portions 30 having a plurality of openings 32 formed therein. The base or lower portion 26 include raised walls 34, 36 formed at the inner and outer edges on one side or surface 33 thereof to form a channel beam like strengthened or stiffened section at the base 26. As shown, the raised walls 34, 36 extend along the edges of 20 until they terminate at 35 on the inner edge before reaching the openings 32, and taper down or end on the outer edge before the end of the window portions 30.

(14) Turning now to FIG. 6, there shown is a cross-sectional view of the nose cone 14, removed from the core housing, showing in detail that the interior waffle impact zone cushion 25 has a plurality of flexible or resilient teeth or fingers 38 against which the lower half round 18 sits or rests when the nose cone is secured to the core housing 12. It is to be understood that these fingers move or flex when force is applied to the exterior of the nose cone, when secured to the core housing, as shown in FIGS. 1-3.

(15) It, therefore, can be seen that the present invention provides an improved shuttlecock that has tail fins with strengthened base portions and a force absorbing nose cone that provide longer life and allow for more enjoyable and extended play time.

(16) Those skilled in the art will appreciate that various adaptations and modifications of the just-described preferred embodiments may be configured without departing from the scope and spirit of the invention. Therefore, it is to be understood that, within the scope of the appended claims, the invention may be practiced other than is specifically described herein.
