Description

Technical Field

[0001] The present invention relates to a fishing line guiding aid provided on a fishing rod. The fishing line guiding aid is used by an angler to guide the fishing line to a desired position on the spool during reeling.

Background Art

[0002] In a so-called bait reel (two-bearing reel), both ends of the central axis (rotation axis) of the spool are supported by bearings. When an angler operates the handle, the spool rotates, and the fishing line is wound up or pulled out along a direction orthogonal to the rotation axis. In order for the fishing line to be evenly wound along the direction of the rotation axis of the spool, a conventional bait reel includes a level wind mechanism (see Patent Document 1). Generally, the level wind mechanism has a cross gear shaft arranged via a gear train parallel to the handle shaft, and the cross gear shaft rotates in conjunction with the rotation of the handle shaft. A level wind is engaged with this cross gear shaft, and due to the rotation of the cross gear shaft, the level wind reciprocates in the direction of the handle shaft, that is, in the direction of the rotation axis of the spool.

[0003] By the way, in fishing targeting large fish (referred to as "big game"), a large tension is generated in the fishing line, so the gear train, cross gear shaft, and level wind need to have appropriate rigidity and mechanical strength. Therefore, the size and weight of these increase, and consequently, the size and weight of the bait reel also increase, and it is undeniable that the operability during actual fishing deteriorates. To solve such inconveniences, in a big game bait reel, the level wind mechanism is deliberately omitted.

[0004] When the level wind mechanism is omitted, the angler's operation is required in order for the fishing line to be evenly wound on the spool. Specifically, when reeling, the angler pinches the fishing line with the thumb and index finger while gripping the front grip of the fishing rod, and reciprocates the thumb and index finger along the direction of the rotation axis of the spool.

[0005] [Patent Document 1] Japanese Patent Publication No. 2021-90380 [Overview of the project] [Problems that the invention aims to solve]

[0006] However, while holding the front grip, it is not easy to move the thumb and index finger, which are pinching the fishing line, back and forth in the direction of the spool's axis of rotation. Moreover, this motion also presents the problem that the angler cannot securely grip the front grip.

[0007] This invention was made against this background, and its purpose is to provide a fishing line guide assisting anglers in the process of winding fishing line evenly onto the spool while reeling. [Means for solving the problem]

[0008] (1) The first side view of the present invention of the fishing line guide aid is applied to a fishing rod having a reel mounting section on top on which a fishing reel is mounted. The fishing line guide aid comprises a fixing section that is positioned in front of the reel mounting section and fixed to the fishing rod, and an auxiliary section formed along the left-right direction on the reel mounting section side of the fixing section to assist in guiding the fishing line in the left-right direction.

[0009] In this configuration, the fixed part is fixed to a predetermined position on the fishing rod, that is, in front of the reel mounting part provided on the fishing rod. In this state, the auxiliary part is positioned on the reel mounting side of the fixed part and extends along the left-right direction. When the fishing line is pulled out from the fishing reel (typically when the rig is cast), the fishing line is positioned above the auxiliary part. Because this auxiliary part is positioned on the reel mounting side, when reeling, the angler can operate the reel handle with one hand and grip the fishing line between the auxiliary part and the fingers of the other hand (for example, the thumb). Moreover, because the auxiliary part extends in the left-right direction, the angler can move the relative position of the fishing line with respect to the spool of the fishing reel from side to side simply by sliding their fingers from side to side when reeling. In other words, the angler can wind the fishing line evenly and easily onto the spool.

[0010] (2) In the fishing line guide aid according to the second aspect of the first aspect of the present invention, the fixing part has an annular part that surrounds at least a part of the fishing rod, and the auxiliary part has an auxiliary surface formed by a part of the outer surface of the annular part.

[0011] With this configuration, the ring portion is fitted onto the fishing rod, so the fishing line guide aid is securely fixed to the fishing rod. The fishing line is held between the angler's fingers and the guide surface. Therefore, the angler can easily slide their fingers from side to side along the guide surface when reeling. As a result, the fishing line is wound onto the spool more easily and evenly.

[0012] (3) In the fishing line guide aid according to the first or second aspect of the present invention, the fixing part has a grip, and the grip is formed integrally with the fixing part.

[0013] With this configuration, the angler can grip the handle with the fishing line sandwiched between the support section. Therefore, the angler's ability to handle the fishing rod is improved, and the fishing line is wound evenly and easily onto the spool.

[0014] (4) In the fourth aspect of the fishing line guide aid according to the third aspect of the present invention, the auxiliary part has an auxiliary surface positioned above the grip.

[0015] With this configuration, anglers can more easily tuck the fishing line between the support surface and the hook.

[0016] (5) In the fifth side of the fishing line guide aid according to any of the first to fourth sides of the present invention, the auxiliary part has an auxiliary surface on which a flat surface is formed.

[0017] In this configuration, the angler can move the fishing line along the auxiliary surface with great ease.

[0018] (6) In the sixth side of the fishing line guide aid according to any of the first to fifth sides of the present invention, the auxiliary part has an auxiliary surface on which an inclined surface is formed that is inclined along the front-rear direction.

[0019] In this configuration, the angler can more easily move the fishing line along the auxiliary surface.

[0020] (7) In the seventh side of the fishing line guide aid according to any of the first to sixth sides of the present invention, the auxiliary part has an auxiliary surface on which left and right curved surfaces are formed that curve along the left and right direction.

[0021] In this configuration, the angler can more easily move the fishing line along the auxiliary surface.

[0022] (8) In the fishing line guide aid of the eighth side according to any of the first to seventh sides of the present invention, the auxiliary part has an auxiliary surface on which a front-to-back curved surface is formed that curves along the front-to-back direction.

[0023] In this configuration, the angler can more easily move the fishing line along the auxiliary surface.

[0024] (9) In the fishing line guiding aid for the ninth side surface according to any one of the first to eighth side surfaces of the present invention, the auxiliary portion has an auxiliary surface formed with a plurality of grooves extending along the left-right direction.

[0025] In this configuration, the fishing line can move more smoothly along the auxiliary surface.

[0026] (10) In the fishing line guiding aid for the tenth side surface according to any one of the first to ninth side surfaces of the present invention, the auxiliary portion has an auxiliary surface extending in the front-rear direction by 5 mm or more and 20 mm or less, and in the left-right direction by 30 mm or more and 60 mm or less.

[0027] In this configuration, the auxiliary portion is designed compactly. Therefore, the angler is not obstructed by the fishing line guiding aid during casting.

[0028] (11) In the fishing line guiding aid for the eleventh side surface according to any one of the first to tenth side surfaces of the present invention, the auxiliary portion has an auxiliary surface with a hardness of 1000 HV or more and 2500 HV or less in the Vickers hardness test.

[0029] In this configuration, the wear resistance of the auxiliary portion is improved, and a comfortable feeling of use can be obtained for the angler.

[0031] Preferred embodiments of the present invention will be described below with reference to the drawings as appropriate. It goes without saying that these embodiments represent only one aspect of the fishing line guide aid according to the present invention, and the embodiments may be modified without altering the essence of the present invention.

[0032] 1. Overview

[0033] Figure 1 is a perspective view of the main part of a fishing rod 11 to which a fishing line guide aid 10 according to one embodiment of the present invention is attached.

[0034] The fishing rod 11 has a fishing rod body 12 and a body support 13, both of which have known structures. In this embodiment, the fishing rod body 12 consists of a single blank. Typically, the fishing rod body 12 is formed from a prepreg (a resin sheet containing carbon fibers) into a cylindrical shape and then fired by heat treatment. However, the fishing rod body 12 may also consist of multiple blanks that are connected in a known jointing manner. Multiple fishing line guides 18 are provided at predetermined positions on the fishing rod body 12. The body support 13 is made of resin, metal, or wood, and in this embodiment, it is formed in a cylindrical shape. The structures of the fishing line guides 18 and the body support 13 are also known.

[0035] In this specification, the longitudinal direction of the fishing rod body 12 is defined as the "axial direction 15". The butt portion 14 side of the fishing rod body 12 is defined as the "rear side 16", and the opposite side is defined as the "front side 17", and the direction including these is the axial direction 15. In the figure, the upper side is defined as the "upper side 19", the lower side as the "lower side 20", and the direction including these is defined as the "up and down direction 21". The direction perpendicular to the axial direction 15 and the up and down direction 19 is defined as the "left and right direction 22".

[0036] Figure 2 is a view along line II in Figure 1, and Figure 3 is a longitudinal cross-sectional view along line III-III in Figure 2.

[0037] As shown in Figures 1 and 3, the main support portion 13 supports the rear end of the fishing rod body 12. Specifically, the rear end of the fishing rod body 12 is inserted into the main support portion 13 from the front side 17 to the rear side 16, and the two are fixed to each other. The main support portion 13 is equipped with a reel seat 23. A seat surface 24 (corresponding to the "reel mounting portion" described in the claims) is provided on the upper side 19 (corresponding to the "upper side" described in the claims) of the reel seat 23. The structure of the reel seat 23 is also known, and a baitcasting reel 25 (corresponding to the "fishing reel" described in the claims) is placed on the seat surface 24 and is detachably attached. In this embodiment, a grip 26 is provided on the rear side 16 of the main support portion 13, and a trigger 27 is provided on the front side 17 of the grip 26.

[0038] Figure 4 shows the state of use of the fishing rod 11, specifically the angler's actions during reeling.

[0039] The fishing line guide assist device 10 is attached to the butt section 14 of the fishing rod body 12. As shown in Figures 1 and 4, when fishing, the angler operates the handle 28 of the baitcasting reel 25 with one hand (the right hand in this embodiment) to wind the fishing line 29 onto the spool 30. At this time, the angler uses the fingers (for example, the thumb) of the other hand (the left hand 31 in this embodiment) to press the fishing line 29 from the upper side 10 to the lower side 20, sandwiching it between the fishing line guide assist device 10 and the reel. By moving the angler's thumb in the left-right direction 22 (in Figure 4, the direction perpendicular to the plane of the paper) at the same time as reeling, the fishing line 29 is wound evenly in the direction of the rotation axis (left-right direction 22) of the spool 30. The structure of the fishing line guide assist device 10 will be described in detail below.

[0040] 2. Structure of the fishing line guide aid

[0041] As shown in Figure 1 (Figures 1 to 4), the fishing line guide aid 10 is provided on the butt section 14 of the fishing rod body 12. The fishing line guide aid 10 according to this embodiment has an aid body 35 and a front grip 34 (corresponding to the "grip" described in the claims).

[0042] As shown in Figures 2 and 3 (Figures 1 to 4), the front grip 34 is formed in a cylindrical shape. The fishing rod body 12 is inserted into the front grip 34, and the butt section 14 is covered by the front grip 34. In this embodiment, the front grip 34 is fixed to the butt section 14 by adhesive or other fastening means. The material of the front grip 34 can be resin, rubber, metal, wood, etc.

[0043] The auxiliary device body 35 has a fixing part 32 and an auxiliary part 33. In this embodiment, the fixing part 32 and the auxiliary part 33 are integrally formed from resin. However, the auxiliary device body 35 may be formed from rubber, metal, wood, etc. instead of resin. Alternatively, the fixing part 32 and the auxiliary part 33 may be formed separately and bonded together. In that case, for example, the fixing part 32 is preferably molded from a material with a Vickers hardness of about 30 HV to 50 HV, and the auxiliary part 33 is preferably made from a material with a Vickers hardness of about 1000 HV to 2500 HV. The effects of selecting such materials will be described later.

[0044] Figures 5 and 6 are perspective and front views of the auxiliary device body 35 (perspective and front views of the main part of the fishing line guide auxiliary device 10). Figure 7 is a cross-sectional view taken along line VII-VII in Figure 6.

[0045] As shown in Figures 5 and 6, the fixing portion 32 is formed in a cylindrical shape and has an annular portion 36 and a fastening portion 37. The direction of the central axis 44 of the annular portion 36 coincides with the axial direction 15. In this embodiment, the thickness 42 of the annular portion 36 in the front-rear direction (axial direction 15) is set to 10 mm. However, this thickness 42 can be appropriately designed to be within a range of approximately 5 mm to 20 mm. The inner diameter 43 of the annular portion 36 is appropriately set according to the outer diameter of the front grip 34. A part of the annular portion 36 is cut along the axial direction 15, and a pair of flanges 38 are formed in this cut portion. These flanges 38 constitute the fastening portion 37. The pair of flanges 38 protrude downward 20 and face each other with a gap 39 between them. The wall thickness 40 of the flanges 38 is designed as appropriate.

[0046] Each flange 38 is provided with a through hole 41 that penetrates in the left-right direction 22. This fixing portion 32 is positioned 17 in front of the seat surface 24 (see Figure 3). That is, the annular portion 36 surrounds the front grip 34. In this embodiment, a bolt (not shown) is inserted through the through hole 41 of the flange 38 and a nut is attached. When this nut is tightened, each flange 38 moves closer to each other, and the fixing portion 32 is fastened to the front grip 34 via the fastening portion 37. In this embodiment, the flange 38 constitutes the fastening portion 37, but the flange 38 may be omitted. In that case, the annular portion 36 elastically deforms (expands in diameter) and fits onto the front grip 34, and the fixing portion 32 is fixed to the front grip 34 by the elastic restoring force of the annular portion 36.

[0047] The auxiliary part 33 is positioned on the upper side 19 of the fixed part 32 and, in this embodiment, is integrally formed with the fixed part 32 as described above. In this embodiment, the auxiliary part 33 has a trapezoidal shape and is continuous with the annular part 36. As shown in Figure 6, the auxiliary part 33 extends outward from the annular part 36 in the left-right direction 22. The length 45 of the auxiliary part 33 in the left-right direction 22 is set to 40 mm. In this embodiment, this length 45 can be appropriately designed to match the width dimension of the spool 30 of the bait reel 25 (see Figure 2) within a range of 30 mm to 60 mm. As shown in Figure 7, the thickness 46 of the auxiliary part 33 in the front-rear direction (axial direction 15) is the same as the thickness 42 of the annular part 36 in this embodiment and is set to 10 mm. However, the thickness 46 of the auxiliary part 33 does not have to be the same as the thickness 42 of the annular part 36 and can be appropriately designed to match a range of 5 mm to 20 mm.

[0048] The auxiliary portion 33 has an auxiliary surface 47. As shown in Figures 6 and 7, in this embodiment, the auxiliary surface 47 is a flat surface. The effects of the auxiliary surface 47 being a flat surface will be described later. This auxiliary surface 47 consists of the upper surface 19 of the auxiliary portion 33. In this embodiment, since the auxiliary portion 33 is continuous with the annular portion 36, the auxiliary surface 47 is formed by a part of the outer circumferential surface of the annular portion 36. As shown in Figures 3 and 4, in this embodiment, the fixing portion 32 is fitted onto the front grip 34, and the auxiliary portion 33 is provided on the upper surface 19 of the fixing portion 32, so the auxiliary surface 47 is located 19 above the front grip 34. The effects of this will be described later.

[0049] 3. Effects and Benefits of Fishing Line Guide Assistance Devices

[0050] As mentioned above (see Figure 4), the fishing line guide assist device 10 is attached to the butt section 14, and when reeling, the angler holds the fishing line 29 with the thumb of their left hand 31 and holds it between the fishing line guide assist device 10 and the line. As the angler operates the baitcasting reel 25, they move the thumb of their left hand 31 from side to side 22, causing the fishing line 29 to be wound evenly onto the spool 30 in the left to right direction 22.

[0051] As shown in the figure, the fixing part 32 is fixed to the front side 17 of the seat surface 24, and the auxiliary part 33 is positioned on the upper side 19 (the side where the seat surface 24 is provided) and extends along the left-right direction 22 (see Figures 1 and 2). Therefore, the fishing line 29 is positioned on the upper side 19 of the auxiliary part 33. Consequently, the angler can easily hold the fishing line 29 between the thumb of their left hand 31 and the auxiliary part 33. Moreover, because the auxiliary part 33 extends in the left-right direction 22, the angler can easily move the relative position of the fishing line 29 with respect to the spool 30 simply by sliding their thumb from side to side while reeling. As a result, the angler can wind the fishing line 29 evenly and easily onto the spool 30.

[0052] In this embodiment, as shown in Figures 4 and 5, the fixing part 32 is fixed to the butt portion 14 of the fishing rod body 12 via the front grip 34. Specifically, the ring portion 36 surrounds and tightens around the butt portion 14, securely fixing the fishing line guide aid 10 to the fishing rod 11. Therefore, the angler can more easily and reliably slide their thumb along the auxiliary surface 47 while holding the fishing line 29 between their thumb and the auxiliary surface 47. In this embodiment, the fixing part 32 is equipped with a front grip 34, but the front grip 34 may be omitted. In this case, the fixing part 32 is directly attached to the butt portion 14. That is, the ring portion 36 is fixed to the butt portion 14 via the fastening part 37.

[0053] In this embodiment, since the auxiliary surface 47 is positioned above the front grip 34 19, the angler can more easily grip the fishing line 29 between the auxiliary surface 47 and the front grip. In addition, since the auxiliary surface 47 is a flat surface, the angler can move the fishing line 29 along the auxiliary surface 47 very easily.

[0054] In this embodiment, as shown in Figures 6 and 7, the auxiliary surface 47 extends approximately 5 mm to 20 mm in the front-to-back direction and approximately 30 mm to 60 mm in the left-to-right direction 22. Therefore, the auxiliary part 33 is designed to be compact while ensuring the operability of the fishing line 29. As a result, anglers also benefit from the fact that the fishing line guide aid 10 does not get in the way when casting.

[0055] In this embodiment, the auxiliary part 33 has a hardness of approximately 1000 HV to 2500 HV in a Vickers hardness test, thus improving the wear resistance of the auxiliary part 33, particularly the auxiliary surface 47. In addition, it provides a comfortable user experience for anglers.

[0056] 4. First variation

[0057] Figure 8 shows the state of use of the fishing line guide assist device 50 according to the first modified example of this embodiment. Figure (a) is a perspective view of the main part of the fishing rod 11 to which the fishing line guide assist device 50 is attached, and Figure (b) is a schematic diagram showing the procedure for use.

[0058] The difference between the fishing line guide aid 50 and the fishing line guide aid 10 in this modified example is that the fixing portion 51 of the fishing line guide aid 50 is integrally formed with the front grip 34. In other words, in this modified example, the front grip 34 and the fixing portion 51 are integrally molded from, for example, resin. Furthermore, the auxiliary portion 33 may be integrally formed with the fixing portion 51, and the front grip 34, fixing portion 51, and auxiliary portion 33 may be integrally molded.

[0059] According to this modification, the angler can easily grip the front grip 34 with the fishing line 29 sandwiched between it and the auxiliary part 33. Therefore, the operability of the fishing rod 11 is improved for the angler, and the fishing line 29 can be wound onto the spool 30 more easily and evenly.

[0060] 5. Second variation

[0061] Figure 9 is a front view of the main part of a fishing line guide aid 55 according to a second modified example of this embodiment. Figure 10 is a front view of the main part of a fishing line guide aid 60 according to another embodiment of this second modified example.

[0062] As shown in Figure 9, the difference between the fishing line guide aid 55 according to this modified example and the fishing line guide aid 10 lies in the shape of the auxiliary part 33. Specifically, in the fishing line guide aid 10, the auxiliary surface 47 of the auxiliary part 33 is a flat surface, whereas in the fishing line guide aid 55, the upper surface 19 of the auxiliary part 33 (auxiliary surface 56) is a curved surface 57 that is convex to the lower side 20 (corresponding to the "left and right curved surfaces" described in the claims). This curved surface 57 is formed symmetrically in the left-right direction 22, and its radius of curvature 58 is set to approximately 30 mm to 200 mm.

[0063] As shown in Figure 10, in the fishing line guide aid 60, the upper surface 19 of the auxiliary part 33 (auxiliary surface 61) is a curved surface 62 that is convex to the upper surface 19 (corresponding to the "left and right curved surfaces" described in the claims). This curved surface 62 is formed symmetrically in the left-right direction 22, and its radius of curvature 63 is set to approximately 30 mm to 200 mm.

[0064] In the modified fishing line guide aids 55 and 60, the auxiliary surfaces 56 and 61 are curved surfaces 57 and 62, respectively, so that anglers can more easily move the fishing line 29 along the auxiliary surfaces 56 and 61.

[0065] 6. Third Variation

[0066] Figures 11 and 12 are a perspective view and a front view of the auxiliary body 66 of the fishing line guide auxiliary device 65 according to a third modified example of this embodiment. Figure 13 is a cross-sectional view taken along line XIII-XIII in Figure 12.

[0067] The main body 66 of the auxiliary tool according to this modified example differs from the main body 35 of the fishing line guide auxiliary tool 10 (see Figures 5 to 7) in the following two points: (1) In the main body 35, the auxiliary part 33 is formed in a trapezoidal shape, whereas the auxiliary part 67 of the main body 66 according to this modified example is formed in a rectangular parallelepiped shape (see Figures 11 and 12); and (2) While the auxiliary surface 47 of the auxiliary part 33 is a flat surface, the upper surface 19 of the auxiliary part 66 (auxiliary surface 70) is a curved surface 68 that curves along the front-rear direction (axial direction 15) (corresponding to the "front-rear curved surface" described in the claims) (see Figures 11 and 13).

[0068] The auxiliary part 67 is integrally formed with the fixed part 32 and has a rectangular parallelepiped shape. The length 69 of the auxiliary part 67 in the left-right direction 22 is set to 40 mm, but can be appropriately redesigned to a range of approximately 30 mm to 60 mm to match the width dimension of the spool 30 of the bait reel 25 (see Figure 2).

[0069] The auxiliary surface 70 is a curved surface 68, as shown in Figures 11 and 13. As shown in Figure 13, the curved surface 68 is curved so as to be convex to the lower side 20 and is formed symmetrically in the front-rear direction (axial direction 15). The radius of curvature 71 of the auxiliary surface 70 is set to approximately 5 mm to 20 mm. In this modified example, the edges 72 of the front side 17 and rear side 16 of the auxiliary surface 70 are chamfered, forming a so-called R surface. However, this chamfering may be omitted.

[0070] In this modified example, since the auxiliary surface 70 is a curved surface 68, the angler can more easily move the fishing line 29 along the auxiliary surface 70.

[0071] 7. Fourth variation

[0072] Figure 14 is a cross-sectional view of the auxiliary body 76 of the fishing line guide auxiliary device 75 according to a fourth modified example of this embodiment.

[0073] The difference between the fishing line guide aid 75 and the fishing line guide aid 10 in this modified example lies in the shape of the auxiliary part 77. Specifically, in the fishing line guide aid 10, the auxiliary surface 47 of the auxiliary part 33 is flat in both the left-right direction 22 and the front-back direction (axial direction 15), whereas in the fishing line guide aid 75, the upper surface 19 of the auxiliary part 77 (auxiliary surface 78) is an inclined surface 79. As shown in the figure, this inclined surface 79 gradually slopes downward 20 from the front side 17 to the rear side 16. In particular, in this modified example, the auxiliary surface 78 is a curved surface that is convex towards the upper side 19. However, the auxiliary surface 78 may also be a flat surface in the vertical direction 21.

[0074] In the modified fishing line guide aid 75, the auxiliary surface 78 is inclined from the front side 17 to the rear side 16, so that the angler can more easily move the fishing line 29 along the auxiliary surface 78. The auxiliary surface 78 may also be inclined from the rear side 16 to the front side 17.

[0075] 8. Fifth variation

[0076] Figure 15 is a plan view of a fishing line guide aid 80 according to a fifth modified example of this embodiment.

[0077] The difference between the fishing line guide aid 80 and the fishing line guide aid 10 in this modified example lies in the shape of the auxiliary part 33, specifically in the fact that a plurality of fine grooves 81 (corresponding to the "grooves" described in the claims) are formed on the auxiliary surface 47. These fine grooves 81 extend along the left-right direction 22 and are arranged in parallel in the front-back direction (axial direction 15). The width and depth dimensions of each fine groove 81 can be modified as appropriate.

[0078] In this modified example, the angler moves the thumb of his left hand 31 in the left-right direction 22 (see Figures 2 and 4), allowing the fishing line 29 to move smoothly along the auxiliary surface 78. [Explanation of symbols]
