Description

Technical Field

[0001] The present invention relates to a two-bearing type fishing reel, a method for modifying a two-bearing type fishing reel, and a modification kit for a two-bearing type fishing reel.

Background Art

[0002] A fishing reel attached to a fishing rod is a fishing tool for winding a fishing line. The fishing reel is classified into a two-bearing type, a spinning type, a spin-cast type, etc. according to the difference in its structure.

[0003] Among these, the two-bearing type fishing reel has a structure in which both ends of a spool shaft, which is a rotating shaft of a spool for winding a fishing line, are supported by ball bearings built into left and right casings. This type of fishing reel has a mechanism for winding the fishing line in a direction perpendicular to the spool shaft while rotating the spool, and thus has an advantage of having a stronger winding force compared to reels of other structures.

[0004] On the other hand, since the fishing line is paid out against the rotational resistance of the spool, it has been difficult to cast a relatively light rig far.

[0005] Regarding this point, in the invention (fishing reel) described in Patent Document 1 below, by reducing the outer diameter of the ball bearing, the frictional resistance during rotation inside the bearing is reduced, thereby improving the rotational performance of the spool.

Summary of the Invention

Problems to be Solved by the Invention

[0007] In other words, the invention described in Patent Document 1 makes it possible to cast a light lure a long distance by reducing the rotational resistance of the spool.

[0008] However, if the rotational resistance of the spool decreases, the moment of inertia increases, and in the latter half of a long cast, the rotational speed of the spool may exceed the line payout speed, making it easier for backlash to occur, where the fishing line is paid out excessively.

[0009] The present invention was developed to solve the aforementioned technical problems and aims to provide a novel fishing reel with improved operability, a method for modifying a fishing reel to improve operability, and a modification kit for a fishing reel. [Means for solving the problem]

[0010] The fishing reel of the present invention, which solves the aforementioned technical problems, is a double-bearing type fishing reel comprising a spool around which fishing line is wound, and a ball bearing attached to a spool shaft which serves as the rotation axis of the spool, wherein the inner diameter of the ball bearing is larger than the outer diameter of the spool shaft, and a spacer is provided to fill the gap between the spool shaft and the ball bearing (hereinafter referred to as "the reel of the present invention").

[0011] In the reel of the present invention, a preferred configuration is one in which multiple ball bearings are fitted onto a single spacer.

[0012] The present invention provides a method for modifying a fishing reel to solve the aforementioned technical problems, and is a method for modifying a double-bearing type fishing reel, characterized by performing the following steps: a debearing step of removing the original ball bearing attached to the spool shaft, which is the rotation axis of the spool around which the fishing line is wound; a diameter enlargement step of partially enlarging the shaft diameter of the spool shaft by attaching a spacer to the position where the original ball bearing was attached; and an external fitting step of fitting a ball bearing having an inner diameter corresponding to the outer diameter of the spacer and an outer diameter corresponding to the outer diameter of the original ball bearing onto the spacer (hereinafter referred to as the "modification method of the present invention").

[0013] The fishing reel modification kit of the present invention, which solves the aforementioned technical problems, is a modification kit for a double-bearing type fishing reel, and is characterized by comprising: a spacer attached to the spool shaft, which is the rotation axis of the spool around which the fishing line is wound, to partially enlarge the shaft diameter of the spool shaft; and a ball bearing having an inner diameter corresponding to the outer diameter of the spacer (hereinafter referred to as the "modification kit of the present invention").

[0014] In the modification kit of the present invention, a preferred embodiment is one in which the spacer is provided with a flange that prevents the ball bearing from coming off. [Effects of the Invention]

[0015] According to the present invention, the operability of fishing reels can be improved. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0017] Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited to these embodiments.

[0018] <The reel 1 of the present invention> The reel 1 of the present invention is shown in FIG. 1. The reel 1 of the present invention is a two-bearing type fishing reel, and includes a "spool (2)", a "ball bearing (3)", and a "spacer (4)".

[0019] - Spool 2 - The spool 2 is a part for winding fishing line in the reel 1 of the present invention, and is configured to rotate about the spool shaft 21 as a rotation center when the handle 11 of the reel 1 of the present invention is rotated. In the present embodiment, the outer diameter of the spool shaft 21 is 3 mm.

[0020] - Ball bearing 3 - The ball bearing 3 is a mechanical element attached to the spool shaft 21 to reduce the friction when the spool 2 rotates. In the present embodiment, a commercially available ball bearing (DDL-1060ZZ: outer diameter 10 mm, inner diameter 6 mm) is used as the ball bearing 3.

[0021] - Spacer 4 - The spacer 4 plays the role of filling the gap between the spool shaft 21 and the ball bearing 3. That is, in the reel 1 of the present invention, the inner diameter of the ball bearing 3 is larger than the outer diameter of the spool shaft 21, so if the ball bearing 3 is directly attached to the spool shaft 21, an annular gap is created between the outer circumference of the spool shaft 21 and the inner circumference of the ball bearing 3. In this embodiment, the spacer 4 is a resin molded product comprising a cylindrical spacer body 41 (inner diameter 3 mm, outer diameter 6 mm) as shown in Figure 2, and a flange (outer diameter 6.5 mm) 42 provided at one end of the spacer body 41.

[0022] <Invention of modification method, invention of modification kit 10> Figure 3 shows the modification method of the present invention. The reel 1 of the present invention is constructed by applying the modification method of the present invention to a commercially available fishing reel 100. The modification method of the present invention includes a "bearing removal process," a "diameter enlargement process," and an "outer fitting process." In this embodiment, a modification kit 10 of the present invention, which includes a spacer 4 and a ball bearing 3, was used to perform the modification method of the present invention.

[0023] -Debearing process- In the aforementioned bearing removal process, the original ball bearing 30 attached to the spool shaft 21, which is the rotation axis of the spool 2 around which the fishing line is wound, is removed. In practice, the spool 2 is removed from a commercially available fishing reel 100 (see Figure 3(a)), and the original ball bearing 30 attached to the spool shaft 21 is removed (see Figure 3(b)). The original ball bearing 30 refers to the original ball bearing that was originally installed in the commercially available fishing reel 100. In this embodiment, the original ball bearing 30 removed had dimensions of an inner diameter of 3 mm and an outer diameter of 10 mm.

[0024] -Diameter expansion process- In the diameter expansion step, the shaft diameter of the spool shaft 21 is partially enlarged by attaching a spacer 4 to the position where the original ball bearing 30 was attached. In this embodiment, the diameter expansion step was performed using a spacer (see Figure 2) 4 attached to the modification kit 10 of the present invention. As a result of the diameter expansion step, the shaft diameter of the portion of the spool shaft 21 to which the spacer 4 is attached is increased from 3 mm to 6 mm.

[0025] -Outer fitting process- In the external fitting step, a ball bearing 3 having an inner diameter corresponding to the outer diameter of the spacer 4 and an outer diameter corresponding to the outer diameter of the original ball bearing 30 is fitted onto the spacer. In this embodiment, the external fitting step was performed using a ball bearing (outer diameter 10 mm, inner diameter 6 mm) 3 attached to the modification kit 10 of the present invention.

[0026] After each of the above steps is completed, the reel 1 of the present invention is constructed by returning the spool 2 to its original position. As shown in Figure 4(a), in commercially available fishing reels 100, the original ball bearing 30 is directly attached to the spool shaft 21, but as shown in Figure 4(b), in the reel 1 of the present invention, the spacer 4 is provided so as to fill the gap between the spool shaft 21 and the ball bearing 3.

[0027] In other words, in the reel 1 of the present invention, the inner diameter (φ1: 6 mm) of the ball bearing 3 attached to the spool shaft 21 is larger than the inner diameter (φ0: 3 mm) of the genuine ball bearing 30. Also, since the ball dimensions of the ball bearing 3 are smaller than those of the genuine ball bearing 30, the frictional resistance of the ball bearing 3 during rotation is reduced. As a result, the rotational resistance of the spool 2 in the reel 1 of the present invention is lower than that of a commercially available fishing reel 100.

[0028] On the other hand, since the ball bearing 3 rotates around the spacer 4, which has a larger diameter than the spool shaft 21, the moment of inertia of the spool 2 becomes smaller than that of a commercially available fishing reel 100.

[0029] In other words, the spool 2 in the reel 1 of the present invention is provided with characteristics such as starting to rotate with less force than a commercially available fishing reel 100, and a shorter time until rotation stops.

[0030] As a result, the reel 1 of the present invention offers improved operability, making it easier to cast relatively light lures and less prone to backlash.

[0031] By the way, in the reel 1 of the present invention in this embodiment, the ball bearing 3 has an outer diameter of 10 mm and an inner diameter of 6 mm, but the dimensions of the ball bearing 3 are not particularly limited as long as it has an inner diameter that corresponds to the outer diameter of the spacer 4 that is fitted to it.

[0032] Furthermore, in the reel 1 of the present invention in this embodiment, the ball bearing 3 is attached to each of the two axes of the spool shaft 21 via the spacer 4. However, the ball bearing 3 may be attached via the spacer 4 to only one of the axes (one axis) of the spool shaft 21.

[0033] Furthermore, in the reel 1 of the present invention in this embodiment, one ball bearing 3 is fitted onto one spacer 4, but as shown in Figure 5, multiple ball bearings 3 may be fitted onto one spacer 4. When multiple ball bearings 3 are fitted onto one spacer 4 in this way, the rated load increases, and thus durability is improved.

[0034] In addition, in the reel 1 of the present invention in this embodiment, the spacer 4 is a resin molded product comprising a cylindrical spacer body 41 (inner diameter 3 mm, outer diameter 6 mm) and a flange (outer diameter 6.5 mm) 42 provided at one end of the spacer body 41 (see Figure 2). However, the shape, dimensions, or material of the spacer 4 are not particularly limited as long as it can fill the gap between the spool shaft 21 and the ball bearing 3.

[0035] Other forms of the spacer 4 include one in which a constricted portion 43 is provided on the other end of the spacer body 41, as shown in Figure 6, and a retaining clip 44 is fitted into the constricted portion 43 after the ball bearing 3 is fitted onto it, thereby preventing the ball bearing 3 from coming off.

[0036] In this embodiment of the modification method of the present invention, the spool 2 is removed from the commercially available fishing reel 100, and then the original ball bearing 30 attached to the spool shaft 21 is removed. However, some commercially available fishing reels 100 have a structure in which the original ball bearing 30 is built into the left and right casings. In this case, the original ball bearing 30 remains inside the casing after the removal of the spool 2. Therefore, after the bearing removal process is performed, it becomes necessary to remove the original ball bearing 30 that remains inside the casing.

[0037] Furthermore, in the modification method of the present invention in this embodiment, the fitting process is performed after the diameter expansion process, but the fitting process may be performed before the diameter expansion process, or the diameter expansion process and the fitting process may be performed simultaneously.

[0038] Furthermore, the present invention can be implemented in various other forms without departing from its spirit or main features. Therefore, the embodiments described above are merely illustrative in all respects and should not be interpreted restrictively. The scope of the present invention is defined by the claims and is not restricted in any way by the text of the specification. Moreover, any modifications or changes falling within the equivalent scope of the claims are all within the scope of the present invention. [Industrial applicability]
