Abstract

PURPOSE:To lighten a reel main body by welding a center frame part and a molded one side case in one body. CONSTITUTION:A left-side case part 1 and a center frame part 15 are individually molded with casting in aluminum dies. Especially, diameter Y of inner peripheral face in an inside space S in the left-side case part 1 is made larger than diameter 'y' of an opening of an annular flange 15A in the center frame part 15 to perform so-called 'NIKU-NUSUMI' (reducing thickness of various parts) for obtaining a sufficient part materials-arranging space and thin wall of the case. The annular flange part 15A is located adjacent to an outer peripheral face of a side wall forming line-receiving part 6A in a spool 6 and inhibits slipping out of wound line from the line-receiving part 6A. Individually molded left-side case part 1 and a center frame part 15 are welded in to one body by welding or pressure welding with opposed side faces of the two parts as welding faces 'a'.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a reel used for bait casting having an outer diameter of approximately 45 mm to 70 mm. A connecting portion for connecting one side case portion having a bearing support portion for the spool and the other side case portion disposed opposite to the one side case portion, and forming a thread storage portion for the spool. A reel body integrally formed with a center frame portion having an annular flange portion located close to the outer circumferential surface of a side wall and having an opening diameter smaller than the inner circumferential surface diameter of the internal space of the one side case portion; Regarding the manufacturing method.

[Conventional technology]

The reel body described above has the following basic features since the one side case portion and the center frame portion are integrated.

In other words, there is a method that connects the one side case part and the center frame part with screws or ``caulking'', or if such a thing is used over a long period of time due to the number of castings, the connecting part will be damaged. The problem is that the annular flange may come into contact with the spool side wall, or the gap between the annular flange and the spool side wall may become large, allowing the thread to come out. Even if casting is carried out several hundred times a day, there is little change in the state of connection between the one sight case part and the center frame part, and the annular collar part and the spool side wall do not change. This has the advantage of avoiding contact phenomena.

In the reel body described above, the internal space of the sight case part is large, each part is arranged with plenty of room, and the side wall of the spool is determined whether it is necessary to reduce weight by thinning the wall or to improve functionality. The opening diameter of the annular flange defined by the diameter of the outer peripheral surface cannot be made very large, so conventionally, the one side case part and the center frame part are integrally formed by a casting method such as die casting. After that, a cutting tool (bite) is inserted through the connecting part side opening of the center frame part and the opening of the annular flange part, and the internal space of the one site case part is made to have a diameter larger than the opening diameter of the annular flange part. It was cut to diameter.

[Invention or problem to be solved]

However, in this case, the internal space of the side case part
Since a cutting process is required to perform the "meat thinning" process, the cutting process takes time, and there is room for improvement.

An object of the present invention is to propose a reel body that can be manufactured in a short process and is lightweight while retaining the advantages of integrating one of the side case parts and the center frame part.

[Means to solve the problem]

A feature of the first invention is that the center frame portion and the one cast side case portion are integrally welded together, and the effects thereof are as follows.

[For production]

That is, the one side case portion is individually cast and molded, and the cast molded one side case portion and the center frame portion are integrally welded together.

Therefore, when the one side case portion is individually cast, a space having an inner circumferential surface diameter larger than the opening diameter of the annular collar portion can be formed in the inner space.

〔Effect of the invention〕

Therefore, the internal space can be made to have a large inner circumferential surface diameter at once through the casting process, and the manufacturing process can be shortened accordingly, while maintaining stability due to integration by welding, and reducing weight and parts arrangement. It has come to maintain various advantages such as reducing the restrictions on

[Means to solve the problem]

A characteristic configuration according to the second invention includes the center frame;
The cast molded one site case part is formed with a welding surface that integrates the center frame part and the one side case part, and the effects thereof are as follows. .

[Effect of work/invention]

The basic operation and effect are the same as those of the first invention, and in addition, as a single reel, there are fewer restrictions on component arrangement in one side case portion, and the design burden is also reduced.

As shown in Figures 2 and 6, the spool shaft (18) on the left side case part (1) has a first gear part (46) for generating a click sound, and a level wind mechanism (R) that powers the spool shaft (18). A member having a second gear portion (47) that transmits the information is fitted and fixed on the outside, and is biased by a link-shaped spring (48) having a slit.

As described later, the alumite processed surface on the outer circumferential surface of the reel body can be protected. One cover (61

(2) As shown in FIG. 1, the left side case part (1) and center frame part (15) are individually molded by aluminum die casting. In particular, the internal space (S
) is made larger than the opening diameter (y) of the annular flange (15A) of the center frame (15), which will be described later, to obtain sufficient space for parts placement and to reduce the wall thickness. In order to achieve this goal, we are doing what is called ``meat-slipping''. The annular collar portion (15A) is located close to the outer peripheral surface of the side wall forming the thread storage portion (6A) of the spool (6), and is located close to the outer peripheral surface of the side wall forming the thread storage portion (6A) for the wound yarn.

■ After cutting, by applying an alumite treatment or painting treatment, the outer circumferential surface of the reel body (A) can be formed into an integrated surface with no steps, and the reel body (A) and the reel body (A) have a bright shine due to the alumite. I can do something.

[Another example]

■ The left side case part (1) may be made of a lightweight metal other than aluminum, and its shape may be approximately circular, and the shape can be changed depending on the usage pattern. (1) and (2) are the side case parts.

As for the O-reel main body (A), either the left or right case part (1
), (2) may be integrally fixed to the center frame portion (15).

The O center frame part (15) is made of forged material other than casting.
It may be manufactured by cutting or the like.

(b) In addition to die casting, other casting methods such as the lost wax method may be used as the casting method.

A separate transmission system to the level wind mechanism (R) will be explained. As shown in Figures 8 and 9, the handle shaft (16
) is engaged with the input gear (1, 9A) of the clutch sleeve (19) to connect the output gear (21) of the drag mechanism (D) attached to the handle shaft (16) to the spool (6). On the other hand, the output gear (58) attached to the handle shaft (16) and the input gear (59) attached to the screw shaft (3) are connected by an intermediate gear (60) to form a level wind. Configure the transmission system to the mechanism (R). Therefore, when the clutch is released and the thread is let out, the level wind mechanism (R) is not activated even by the rotation of the spool (6).
Power loss can be prevented by reducing the resistance to the yarn being fed out.

It should be noted that the present invention is not limited to the structure shown in the accompanying drawings by adding reference numerals in the claims for convenient comparison with the drawings.
