Claims
- 1. A wind instrument having a wind passage for producing a sound comprising:
- a first tubular member having a tubular portion and an integrally formed coupling portion having a leading end for guiding a second tubular member into said first tubular member, said tubular portion defining a first inner space having a first inner diameter, said coupling portion having a second inner diameter, said second inner diameter at said leading end being greater than said first inner diameter, and a major portion of said leading end winding radially inward towards said first inner space for forming a second inner space in communication with said first inner space.
- 2. The wind instrument having a wind passage as set forth in claim 1, including a second tubular member coupled to said tubular portion through said coupling portion, said second tubular member defining a third inner space in communication with said first inner space.
- 3. The wind instrument as set forth in claim 2, in which said second tubular member includes an outer diameter, and said second inner diameter of said coupling portion is greater than said outer diameter.
- 4. The wind instrument as set forth in claim 1, in which said tubular portion has an outer surface and said coupling portion has a boss sub-portion merged with said leading end, said sub-portion projecting radially outward from said outer surface of said tubular portion.
- 5. The wind instrument as set forth in claim 1, in which said second inner space has a maximum length and the maximum length of said second inner space is less than said first inner diameter of said tubular portion.
- 6. The wind instrument as set forth in claim 1, in which said first tubular member is plated with a metal coating.
- 7. The wind instrument as set forth in claim 1, in which the leading end extends along the circumference of the coupling portion, and winds radially inward towards the first inner space along the circumference of the coupling portion.
- 8. A wind instrument having a wind passage for producing a sound comprising:
- a first tubular member plated with a coating film and having a tubular portion including an outer surface, said tubular portion defining a first inner space having a first inner diameter, and said tubular portion including an integrally formed coupling portion having a second inner diameter for guiding a second tubular member into said first tubular member, said coupling portion including a leading end sub-portion and an integral boss sub-portion, said second inner diameter at said leading end sub-portion being greater than said first inner diameter, said boss sub-portion projecting radially outward from said outer surface of said tubular portion, and said leading end sub-portion winding radially inward from said boss sub-portion substantially about the circumference of said leading end sub-portion for forming a second inner space in communication with said first inner space, said second inner space having a maximum length and said maximum length being less than said first inner diameter; and
- a second tubular member having an end portion coupled to said tubular portion through said coupling portion, said second tubular member defining a third inner space in communication with said first inner space, said end portion including an outer diameter which is less than the second inner diameter.
- 9. A process for forming a tubular member incorporated in a wind instrument, comprising the steps of:
- a) providing a tubular member having an outer surface, said tubular member including a tubular portion and an integrally formed coupling portion for guiding a second tubular member into said first tubular member, said coupling portion having a leading end and an integrally formed boss portion, said tubular portion defining a first inner space and said coupling portion having an inner diameter;
- b) increasing the inner diameter of said coupling portion;
- c) projecting said boss portion radially outward from said outer surface of said tubular member; and
- d) winding said leading end radially inward from said boss portion substantially about the circumference of said leading end for forming a second inner space in communication with said first inner space.
- 10. The process as set forth in claim 9, in which said tubular member is plated by dipping into an electrolyte after said step of winding inward said leading end.
- 11. A wind instrument having a wind passage for producing a sound comprising:
- a first tubular member having a tubular portion and an integrally formed coupling portion having a leading end for guiding a second tubular member into said first tubular member, said tubular portion including an outer surface and defining a first inner space having a first inner diameter, said coupling portion having a second inner diameter and a boss sub-portion merged with said leading end, said boss sub-portion projecting radially outward from said outer surface of said tubular portion, and said second inner diameter at said leading end being greater than said first inner diameter, and said leading end winding radially inward towards said first inner space substantially along the circumference of said leading end for forming a second inner space in communication with said first inner space.
- 12. A wind instrument having a wind passage for producing a sound comprising:
- a first tubular member having a tubular portion and an integrally formed coupling portion having a leading end for guiding a second tubular member into said first tubular member, said leading end extending continuously along the circumference of the coupling portion, said tubular portion defining a first inner space having a first inner diameter, said coupling portion having a second inner diameter, said second inner diameter at said leading end being greater than said first inner diameter, and said leading end winding radially inward towards said first inner space continuously along at least half of the circumference of the coupling portion for forming a second inner space in communication with said first inner space.
