Embodiment Construction

[0031] A typical plastic shuttlecock has two parts, a base and a skirt. The base can be a homogeneous unit, usually plastic foam, or a composite of different materials, usually cork with a fabric covering. The skirt fits into the base by pushing the annular wall into a clearance hole recessed into the base.

[0032] figure 1 The skirt of the shuttlecock of the present invention is shown. The skirt 10 includes a stem portion 12 and a separately molded flight portion 14 . Wherein, the shaft is formed by a longitudinally extending shaft 16 simulating the shaft of a badminton feather. The shafts 16 are interconnected at a narrow portion by an annular wall 18 together with a plug 20 which is normally used to hold the skirt 10 on the base of the shuttlecock (not shown).

[0033] The stems 16 are interconnected at their ends remote from the base by annular flanges 22 and are reinforced in their middle by an annular reinforcing rib 24 . The rib 24 can be formed with an undercut, ...

Abstract

The invention describes a shuttlecock having a base and a plastics conical skirt (10). The skirt comprises, at its end narrower adjacent the base, a stem portion (12) formed of a plurality of longitudinally extending stems (16) and, at its wider end a flight portion (14) within which a web extends between the individual stems to increase the aerodynamic drag on the shuttle. An annular reinforcement rib (22) or (30) extends between the stems (16) at the junction between the stem and flight portions of the skirt. The reinforcement rib (22) or (30) protrudes from the stems (16) into the interiorof the skirt (10) and has a smaller inside diameter at its tip than points on the inner surface of the flight portion nearer to the base. This is facilitated by forming the skirt from two initially separate conical-conical components.

Description

technical field [0001] The present invention relates to shuttlecocks. Background technique [0002] A shuttlecock, also referred to here as a shuttle, is a projectile used in badminton that has an open conical shape with greater aerodynamic resistance. The cone is usually formed from multiple overlapping goose feathers embedded within a circular cork base covered by a thin leather. This shape of the shuttlecock makes it particularly stable aerodynamically, and regardless of its initial orientation, it will turn to fly base first and keep it flying base first during flight. [0003] The feathers of traditional badminton are brittle and fragile. As a result, several shuttlecocks are replaced in one game. For this reason, artificial shuttlecocks have been developed to replace feathers with plastic skirts. The skirt, near the base, also referred to herein as the stem, consists of a plurality of longitudinal bars simulating the shafts of feathers. The stems are connected to ...
