Abstract
A method of forming a baitcasting reel is disclosed, the baitcasting reel being formed by two end cases provided on either end of a spool and connected by an integral reel body. The reel body may form a portion of either of the end cases. Each of the cases forms a wall having a spool inserting opening which may be formed by the reel body. Further, each of the cases are enclosed by an outer wall portion.
Claims21
A method of manufacturing a baitcasting reel, comprising the steps of:
- forming a one-piece integral unit, said unit including at least:
- a first case having a first inner wall and a first outer wall,
- a portion of a second case having a second inner wall, and
- a thumb rest interconnecting said cases, said unit being formed such that said first and second inner walls are opposite one another and provide support for a level wind mechanism;
- forming spool inserting openings in said first and second inner walls;
- providing a second outer wall for substantially covering said spool inserting opening formed in said second inner wall, said second outer wall positioned generally parallel to said first outer wall;
- and
- forming a substantially cylindrical first interior space inside said first case and between said first inner wall and said first outer wall, with the diameter of said first interior space being greater than the diameter of said spool inserting opening formed in said first inner wall.
A method of manufacturing baitcasting reel, comprising the steps of:
- forming an integral unit, said unit including at least a first inner wall portion of a first case, at least a second inner wall portion of a second case, and a thumb rest interconnecting said inner wall portions, said unit being formed such that said first and second inner wall portions support a level wind mechanism;
- forming spool inserting openings in said first and second inner wall portions;
- and
- providing a first interior space in said first case by unremovably attaching a first outer wall to said integral unit such that said first interior space is substantially cylindrical and is formed between said first outer wall and said first inner wall portion and such that the diameter of said first interior space is greater than a diameter of said spool inserting opening formed in said first inner wall portion of said first case,
- providing a second interior space in said second case by unremovably attaching said second outer wall to said integral unit such that said second interior space is substantially cylindrical and is formed between said second outer wall and said second inner wall portion and such that the diameter of said second interior space is greater than a diameter of said spool inserting opening formed in said second inner wall portion of said second case.
A method of manufacturing a baitcasting reel, comprising the steps of:
- forming a one-piece integral unit, said unit including at least:
- a first case having a first inside wall and a first outer wall continuously formed with said first inside wall;
- a second inside wall opposite said first inside wall for supporting a level wind mechanism, and
- a thumb rest interconnecting said first inside wall and said second inside wall, and
- forming spool inserting openings in said first and second inside walls;
- providing a second outer wall for substantially covering said spool inserting opening formed in said second inside wall, said second outer wall positioned generally parallel to said first outer wall;
- and
- providing a spool support on each of said first and second outer walls;
- forming a substantially cylindrical first interior space inside said first case to define said first inside wall and said first outer wall and to define said first outer wall covering said spool inserting opening in said first inside wall, the diameter of said first interior space being greater than the diameter of said spool inserting opening formed in said first inside wall.
A method of manufacturing a baitcasting reel body, said reel body comprising:
- a first case having an inside wall and an outside wall, a second case provided opposite the first case, the second case having an inside wall and an outside wall, interconnecting members connecting the first case to the second case, said method comprising the steps of:
- forming a one-piece center frame, the center frame including the first case, the inside wall of the second case and the interconnecting members;
- forming the inside and outside walls in the first case by removing material from within the first case;
- forming spool openings in said inside walls of the first and second cases;
- and
- attaching the outside wall of the second case to said center frame to cover the inside wall of the second case.
A method of manufacturing a baitcasting reel body, said reel body comprising:
- a first case having an inside wall and an outside wall, a second case provided opposite the first case, the second case having an inside wall and an outside wall, interconnecting members connecting the first case to the second case, said method comprising the steps of:
- injection molding a center frame, the frame including the first case, the inside wall of the second case and the interconnecting members;
- cutting material out of an interior of the first case to form the inside and outside walls of the first case;
- and
- forming spool openings in said inside walls of the first and second cases.
A method of manufacturing a baitcasting reel body, said reel body comprising:
- a first case having an inside wall and an outside wall, a second case provided opposite the first case, the second case having an inside wall and an outside wall, interconnecting members connecting the first case to the second case, said method comprising the steps of:
- cutting, from a block of metal, a center frame, the frame including the first case, the inside wall of the second case and the interconnecting members;
- cutting material out of an interior of the first case to form the inside and outside walls of the first case;
- and
- forming spool openings in said inside walls of the first and second cases.
