Claims22
A shuttlecock, comprising:
- a cock unit, a feather support and a feather unit connecting together, wherein said cock unit and said feather support are able to be either made and formed integrally in one step or made independently in separate steps and then connected together, wherein each of said feather units has an upper portion defining a feather member and a bottom portion defining a shaft member which unit is inserted into said feather support, wherein said feather unit is made of feathers selected from a group selected from natural goose feathers, primaries of duck wings and synthetic materials, wherein said feather unit further has a stem portion which is internally, externally or internally and externally coated with reinforcing materials, wherein said reinforcing materials for coating said stem portion internally is macromolecular polymer and said reinforcing materials for coating said stem portion externally is reinforcing glue.
A shuttlecock, comprising:
- a cock unit, a feather support and a feather unit connecting together, wherein said cock unit and said feather support are able to be either made and formed integrally in one step or made independently in separate steps and then connected together, wherein each of said feather units has an upper portion defining a feather member and a bottom portion defining a shaft member which unit is inserted into said feather support, wherein said shaft member has a length of not more than one third of a length of said feather unit.
A shuttlecock, comprising:
- a cock unit, a feather support and a feather unit connecting together, wherein said cock unit and said feather support are able to be either made and formed integrally in one step or made independently in separate steps and then connected together, wherein each of said feather units has an upper portion defining a feather member and a bottom portion defining a shaft member which unit is inserted into said feather support, wherein said feather support comprises a plurality of feather connecting members, wherein said shaft members of said feather units are securely connected to said feather connecting members respectively, wherein each of said feather connecting members has a tubular end and each of said shaft members of said feather units has a tapered end adapted to be inserted into said tubular end of said respective feather connecting member.
A shuttlecock, comprising:
- a feather support;
- a cock unit provided at a first of said feather support;
- and a plurality of feather units provided at a second end of said cock unit, wherein each of said feather units is made from a natural feather having a length of 39-45 mm, wherein each of said feather units has a feather member and a shaft member and said feather support comprises a plurality of feather connecting members, wherein each of said feather connecting members has a tubular end and each of said shaft members of said feather units has a tapered end adapted to be inserted into said tubular end of said respective feather connecting member.
A method of manufacturing shuttlecock, comprising the steps of:
- (a) providing a plurality of feather units each having an upper portion defining a feather member and a bottom portion defining a shaft member with a length not more than one third of a length of said feather unit;
- (b) inserting said shaft members of said feather units into a plurality of feather connecting members of a feather support respectively;
- and (c) positioning said feather support into a cock unit to form a shuttlecock.
