Abstract

PROBLEM TO BE SOLVED: To effectively reduce the weight of a spool in the spool of a double bearing reel. SOLUTION: This spool 4 of the double bearing reel comprises a flange part, a line winding barrel part and a shaft mounting part integrally formed on the inner peripheral side of the line winding barrel part. The line winding barrel part has circular through-holes 40 passing through the inner and outer peripheries in two rows at an interval in the axial direction and 8 sites for one row in the peripheral direction. Wall gouging parts 50 having the same diameter as that of the through-holes 40 are further formed in 8 sites in one row in the peripheral direction so as to reach the shaft mounting part. Since the wall gouging parts 50 are formed in the shaft mounting part, the weight of the spool 4 can effectively be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spool,
The present invention relates to a dual-bearing reel spool rotatably supported on a reel body and mounted on a spool shaft.

[0002]

2. Description of the Related Art Generally, a dual-bearing reel includes a reel body having a handle and a spool rotatably mounted on the reel body. The spool has a bobbin trunk on which the fishing line is wound around the outer periphery, flange portions provided at both ends of the bobbin trunk, and a shaft mounting portion provided on the inner peripheral side of the bobbin trunk. The bobbin trunk has a cylindrical shape, and the flange has a larger diameter than the outer diameter of the bobbin trunk. The shaft mounting portion is formed integrally with the bobbin trunk, for example, and the inner peripheral side is mounted on the spool shaft.

In such a spool, it is desired to reduce the weight of the spool and reduce its inertia in order to improve the casting force. Therefore, in order to reduce the weight of the spool, for example, a spool having a through-hole penetrating a cylindrical bobbin trunk is known.

[0004]

In a conventional spool having a through hole, a through hole is provided in a cylindrical bobbin trunk. However, even if the through-hole is formed in the cylindrical bobbin trunk portion having a relatively small thickness, only a small portion of the bobbin trunk portion is reduced in weight. Therefore, it is difficult to reduce the weight of the spool as a whole.

An object of the present invention is to effectively reduce the weight of a spool of a dual bearing reel.

[0006]

A dual-bearing reel spool according to a first aspect of the present invention is a dual-bearing reel spool rotatably supported on a reel body and mounted on a spool shaft. A bobbin trunk portion, an inner peripheral portion mounted on a spool shaft, a shaft mounting portion connected to the outer periphery so as to form a space in the bobbin trunk portion, and flange portions provided at both ends of the bobbin trunk portion. I have. A stolen portion is formed from the outer periphery of the bobbin trunk to the inside of the shaft mounting portion.

In such a spool, the thickness of the shaft mounting portion, which occupies most of the mass of the spool, is formed with a thickness-removing portion, so that the weight of the spool can be effectively reduced.

According to a second aspect of the present invention, there is provided the spool of the first aspect, wherein the meat robbing portions are provided at a plurality of locations at predetermined intervals in the circumferential direction of the bobbin trunk.

In this case, since a plurality of robbing portions are formed in the circumferential direction, a large number of robbing portions can be arranged. Therefore, the weight of the shaft mounting portion is reduced,
The spool can be made lighter.

According to a third aspect of the present invention, there is provided the spool according to the first or second aspect, wherein the robbing portion is a through-hole penetrating the shaft mounting portion. Is further reduced in weight, so that the weight of the spool can be further reduced.

A spool according to a fourth aspect of the present invention is the spool according to any one of the first to third aspects, wherein the thickness of the meat stealing portion is circular.

[0012] In this case, for example, using a cutting drill or the like, it is possible to easily form a circular stolen portion.

A spool according to a fifth aspect of the present invention is the spool according to any one of the first to third aspects, wherein the shape of the meat stealing portion is non-circular.

In this case, for example, by forming the meat stealing portion shifted from the spool shaft, the shape of the meat stealing portion can be made non-circular.

According to a sixth aspect of the present invention, in the spool according to any one of the first to fifth aspects, the axial length of the bobbing portion of the bobbin trunk is longer than the axial length of the portion having the robbing portion of the shaft mounting portion. .

In this case, the weight of the spool can be further reduced by forming, for example, a robbing portion penetrating in the axial direction of the shaft mounting portion.

According to a seventh aspect of the present invention, in the spool according to any one of the first to sixth aspects, the minimum outer diameter of the bobbin trunk is in the range of 40% to 80% of the maximum outer diameter of the flange. Since the bobbin trunk is made shallow, the effect of reducing inertia due to stealing becomes significant. In addition, even when a thin fishing line is wound around the spool, a winding habit is unlikely to occur. In the case of such a shallow groove spool, since the outer diameter of the bobbin trunk is large, it is desirable to provide a space inside to reduce the weight.

According to an eighth aspect of the present invention, in the spool according to any one of the first to seventh aspects, the maximum outer diameter of the flange portion is in a range of 30 mm or more and 60 mm or less.

In this case, the dimensions are easy to use for casting such as summing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A dual-bearing reel adopting an embodiment of the present invention is a low profile type reel for bait casting, as shown in FIGS. The dual-bearing reel includes a reel body 1, a handle assembly 2 for rotating a spool disposed on the side of the reel body 1, and a spool for winding a spool which is rotatably and detachably mounted inside the reel body 1. 4 is provided. A star drag 3 for drag adjustment is provided on the reel body 1 side of the handle assembly 2.

The reel body 1 has a frame 5, side covers 6 mounted on both sides of the frame 5, and a front cover 7 covering the front of the frame 5.

As shown in FIGS. 3 to 5, the spool 4 has a dish-shaped flange 4a on both sides and two flanges 4a.
a and a bobbin trunk 4b formed between the
and a shaft mounting portion 4c integrally formed at the center so as to have a space on the inner peripheral side of b. The spool 4 is
It is non-rotatably fixed to a spool shaft 10 that passes through the shaft mounting portion 4c. The spool shaft 10 is rotatably supported by a bearing provided on the side cover 6. The outer diameter of the bobbin trunk 4b is 40 times the outer diameter of the flange 4a.
% To 80%, and constitutes a so-called shallow groove spool. The outer diameter of the flange portion 4a is in a range from 30 mm to 60 mm.

As shown in FIGS. 1 to 4, the bobbin trunk 4b is provided with two circular through-holes 40 penetrating the inner and outer peripheries, each of which is cut in eight rows in the circumferential direction at intervals of two rows. Is formed. Between the two rows of through holes 40, one more
Rows, eight locations in the circumferential direction, the thickness of the through-hole 40 and the thickness of the thief portion 50
Are formed by cutting so as to reach the shaft mounting portion 4c. The through-hole 40 and the stolen portion 50 are arranged so that their phases are shifted in the circumferential direction.

Since the meat stealing part 50 is formed by using a cutting drill or the like from the outer periphery of the bobbin trunk part 4b toward the shaft mounting part 4c, the bottom part of the meat stealing part 50 has a sharp shape. Further, the axial length of the robbing portion 50 of the bobbin trunk 4b is formed to be longer than the axial length of the portion having the robbing portion 50 of the shaft mounting portion 4c, as shown in FIG. The meat stealing part 50 penetrates part of the shaft mounting part 4c in the axial direction.

In such a spool 4, a robber portion 50 is formed on the shaft mounting portion 4c which occupies most of the mass of the spool 4. Therefore, by reducing the weight of the shaft mounting portion 4c, the weight of the spool 4 can be reduced effectively.
