Description

Technical Field

[0001] This invention relates to fishing reels. Background Technology

[0002] Conventionally, in fishing reels that include a reel body with a handle, a spool rotatably mounted on the reel body, and a handle for rotating the spool, it is known that rotating the handle causes the spool to rotate in the direction of reel winding, thereby winding the fishing line onto the spool.

[0003] Patent documents Patent Document 1: Japanese Patent Application Publication No. 2024-85772 Summary of the Invention

[0004] Related to such fishing reels, for example, Patent Document 1 discloses a fishing reel comprising: a reel body mounted on a fishing rod; a handle rotatably disposed on the reel body; and a spool that rotates in conjunction with the rotation of the handle in the direction of winding the fishing line. A winding load reduction mechanism is provided between the handle and the spool to reduce uneven winding force on the fishing line generated during the rotation of the handle.

[0005] However, in the fishing reel in Patent Document 1, there is a structure with two one-way clutches between the handle and the drum. When the inner ring of the two one-way clutches is the drive shaft, the twisting of the drive shaft will cause end collisions at two points (both ends) between the two one-way clutches and the drive shaft. This will cause damage to the rotating parts inside the one-way clutches and increase the load on the remaining rotating parts. As a result, there is a problem that the reverse rotation prevention function of the one-way clutches is greatly reduced.

[0006] The present invention was made in view of the above-mentioned circumstances, and the technical problem to be solved is to provide a fishing reel that can reduce the damage of the one-way clutch located on the handle drive shaft that ultimately bears the force, even when a strong tension is generated on the reel during fishing, and can suppress the reduction of its reverse reversal prevention function. Other than the above-mentioned objectives of the present invention will be apparent from the entire specification.

[0007] To achieve the above objectives, the fishing reel of the present invention comprises: a reel body; an operating part disposed on the reel body; a spool disposed on the reel body for winding fishing line by a winding operation of the operating part; a handle drive shaft disposed on the reel body and on which the operating part is mounted; and a plurality of one-way clutches arranged axially on the handle drive shaft, characterized in that each of the plurality of one-way clutches comprises: an inner ring; a retainer disposed on the outer side of the inner ring; a plurality of rotating parts held by the retainer; and an outer ring disposed on the outer side of the retainer, wherein the inner ring is disposed on each of the plurality of one-way clutches.

[0008] In one embodiment of the invention, the inner ring is anti-rotationally engaged with the handle drive shaft.

[0009] In one embodiment of the invention, the inner ring is formed of a material that is harder than the handle drive shaft.

[0010] In one embodiment of the present invention, when viewed axially from the handle drive shaft, the length of the inner ring is 5mm to 20mm.

[0011] In one embodiment of the invention, the inner rings of each of the plurality of one-way clutches are configured such that, when viewed axially from the handle drive shaft, adjacent ends are in contact with each other.

[0012] In one embodiment of the invention, a plurality of the one-way clutches are configured such that, when viewed axially from the handle drive shaft, adjacent ends are spaced apart from each other.

[0013] According to the present invention described above, a fishing reel can be provided that can reduce the breakage of the one-way clutch that ultimately bears the force even when a strong tension is generated on the reel during fishing, and can suppress the reduction of the reverse reversal prevention function.

Detailed Implementation

[0015] The following description, using a dual-bearing type reel as an example, details the implementation of the fishing reel according to the present invention with reference to the accompanying drawings. In the multiple drawings, common components are labeled with the same reference numerals. For ease of explanation, the drawings are not necessarily described to an exact scale; this should be noted.

[0016] First, refer to Figure 1 The basic structure of a fishing reel according to one embodiment of the present invention will be described. Figure 1 This diagram illustrates the basic structure of a fishing reel according to one embodiment of the present invention.

[0017] The fishing reel 10 includes a reel body 1, which has a left frame 2a, a right frame 2b, and a left side plate 1A and a right side plate 1B that cover the left frame 2a and right frame 2b with a left side cover plate 3a and a right side cover plate 3b, respectively. A spool 5 is rotatably supported between the left side plate 1A and the right side plate 1B by bearings (not shown). A spool 7 for winding fishing line is integrally fixed to the spool 5. The spool 7 has a line-winding body 7a and flanges 7b integrally formed on its left and right sides. The fishing line is wound around the line-winding body 7a by the left and right flanges 7b.

[0018] A mounting plate 2A is provided on the fishing reel 10, which together with the described left frame 2a forms a frame structure, and can also be integrally mounted on the left cover plate 3a. In this case, when the left cover plate 3a is removed from the left frame 2a, the mounting plate 2A also detaches integrally from the left cover plate 3a, exposing the drum opening 2d formed on the left frame 2a, which facilitates the removal of the drum 7 and improves maintainability.

[0019] As described above, the spool 7 has a line winding body 7a and flanges 7b integrally formed on its left and right sides. Furthermore, it is configured to be generally cylindrical, so that when it is rotated clockwise, the fishing line can be wound onto the outer periphery of the line winding body 7a. One of the pair of bearings (not shown) that rotate and support the spool 7 is fixed to the left frame 2a of the reel body 1, and the other is fixed to the mounting plate 2A.

[0020] Mounting plate 2A can be fixed to the left frame 2a by screws, as described later. Alternatively, a bayonet structure can be used to detach the drum 7 and mounting plate 2A from the left frame 2a. This bayonet structure engages with a retaining part on the frame 2 by rotating multiple claws on a locking member. Fixing can also be achieved by adhesive or other methods; the fixing method is not particularly limited. By fixing mounting plate 2A to the left frame 2a, the drum 7 is supported by a rotatable shaft. Furthermore, a braking part (not shown) can be formed by holding a fixed magnet and a movable magnet (not shown) on mounting plate 2A.

[0021] The left frame 2a and right frame 2b constituting the reel body 1 can be mounted on a fishing rod. The fishing reel 10, like existing fishing reels, has an operating part (handle) 8, which can wind up the fishing line when the user rotates the spool 7 in the forward direction. In addition, for the sake of simplicity, some known functions are omitted from the reel body.

[0022] Furthermore, a handle 8 for rotating and driving the drum 7 is provided on the left side plate 1A. A known power transmission mechanism for the drum is provided in the space S (gearbox S) between the left frame 2a and the left cover plate 3a to transmit the rotational driving force of the handle 8 to the drum shaft 5. The power transmission mechanism for the drum includes: a drive gear 11, rotatably supported on a handle drive shaft 8a on which the handle 8 is mounted; and a pinion 12, held to move axially on the drum shaft 5 and meshing with the drive gear 11.

[0023] Multiple rolling one-way clutches 100 are provided on the handle drive shaft 8a. Each rolling one-way clutch 100 has: an inner ring 13, which is anti-rotationally engaged with the handle drive shaft 8a; a retainer 14, which is disposed outside the inner ring 13; and an outer ring 15, which is disposed outside the retainer 14. On the inner circumferential surface of the outer ring 15, there is a free rotation area where multiple rotating parts 16 held by the retainer 14 can rotate freely, and a wedge area that prevents the rotation of the multiple rotating parts 16. Each rotating part 16 is always forceped towards the wedge area by a spring member provided on the retainer 14. In this configuration of one-way clutches 100, when the inner ring 13 rotates clockwise with the pinion 12, the rotating parts 16 of the retainer 14 are located in the free rotation area of ​​the outer ring 15. Therefore, the rotational force of the inner ring 13 is not transmitted to the outer ring 15 (it is not prevented by the outer ring 15), and thus the handle drive shaft 8a can rotate without obstruction. Conversely, when the inner ring 13 reverses along with the handle drive shaft 8a, the rotating part 16 of the retainer 14 is located in the wedge region of the outer ring 15. Therefore, the rotational force of the inner ring 13 is transmitted to the outer ring 15, which acts as a stop, thus preventing the rotation (reverse reversal) of the handle drive shaft 8a. Further details regarding the multiple rolling one-way clutches 100 will be described later.

[0024] Furthermore, a known force-relieving mechanism 15 is provided on the drive gear 11. This force-relieving mechanism 15 engages frictionally between the handle shaft drive 8a and the drive gear 11, causing the drive gear to generate a predetermined braking force. The braking force can be adjusted by rotating the force-relieving handle (also known as a star-shaped force-relieving brake) 17 mounted on the handle drive shaft 8a to change the contact pressure of the brake plate 15a that contacts the drive gear 11.

[0025] Furthermore, the fishing reel 10 has a clutch mechanism 20, which allows the user to select whether to connect or disconnect the power transmission to the drum 7 by operating the switching operation component (not shown) of the clutch mechanism (clutch unit) 20. In the connected state, the reel can be wound up by the operation unit, and in the unconnected state, the drum 7 can be freely rotated in both directions to release the fishing line.

[0026] Next, refer to again Figure 1 and Figure 2 Further explanation of the fishing reel 10.

[0027] Figure 2 This is a partial enlarged view of a fishing reel 10 according to one embodiment of the present invention, and is a diagram that provides a more detailed description of the fishing reel 10.

[0028] like Figure 1 , 2As shown, the fishing reel 10 includes: a reel body 1; an operating part 8 disposed on the reel body 1; a spool 7 disposed on the reel body 1, which winds the fishing line by the winding operation of the operating part 8; a handle drive shaft 8a disposed on the reel body 1, on which the operating part 8 is mounted; and multiple one-way clutches 100 (in... Figure 2 The example shown has two one-way clutches, arranged axially along the handle drive shaft 8a. Each of the multiple one-way clutches 100 has: an inner ring 13; a retainer 14 disposed outside the inner ring 13; multiple rotating parts 16 held by the retainer 14; and an outer ring 15 disposed outside the retainer 14. The inner ring 13 is provided on each of the multiple one-way clutches 100. Here, the number of multiple one-way clutches 100 can be two, three, or more, and is not limited to a specific number, but the inner ring 13 is provided individually on each of the multiple one-way clutches 100.

[0029] The inner ring 13 engages with the handle drive shaft 8a to prevent rotation. At this time, since the load on the inner ring 13 is relatively large when it reverses, it is possible to reduce the damage to the inner ring by using a material that is harder than the handle drive shaft 8a.

[0030] Furthermore, when viewed along the axial direction of the handle drive shaft 8a, the length of the inner ring 13 is preferably about 5mm to 20mm. This allows for a compact overall design while covering the length of the rotating component 16 in the same direction, and enables stable installation.

[0031] The inner rings 13 of the multiple one-way clutches 100 are arranged such that, viewed axially from the handle drive shaft 8a, adjacent ends are in contact with each other (in... Figure 2 In this example, the two inner rings 13 are configured such that, viewed axially from the handle drive shaft 8a, adjacent ends are in contact with each other. This enables the transmission of the force input from the star-shaped drain brake to the drain washer along the handle drive shaft.

[0032] Multiple one-way clutches are configured such that, viewed axially from the handle drive shaft, adjacent ends are spaced apart from each other. This prevents them from interfering with each other even when a load is applied in the torsional direction, thus helping to reduce breakage.

[0033] As described above, the fishing reel 10 according to the present invention can support the deformation of the handle drive shaft, which ultimately bears the force, at two locations on the inner rings of each of the multiple one-way clutches, even when strong tension is applied to the reel during fishing. This reduces the risk of breakage of the one-way clutches and suppresses the reduction in their anti-reverse function. In particular, when the handle drive shaft is used as the inner ring of the one-way clutch, or when a common inner ring is used for multiple one-way clutches, end collisions occur in the inner ring when a load is applied to the handle drive shaft and the handle drive shaft tilts, leading to a reduction in the function of the one-way clutch. However, as with the present invention, by providing dedicated inner rings that are separate from the handle drive shaft and each of the multiple one-way clutches 100 has its own, tilting caused by the load applied to the handle drive shaft can be absorbed more effectively. Furthermore, end collisions of the one-way clutches can be reduced, preventing a reduction in the function of the one-way clutches.

[0034] The dimensions, raw materials, and configurations of the constituent elements described in this specification are not limited to those explicitly stated in the embodiments. These constituent elements can be modified within the scope of this invention to have arbitrary dimensions, raw materials, and configurations. Furthermore, constituent elements not explicitly stated in this specification may be added to the described embodiments, and some constituent elements described in each embodiment may be omitted.
