[0002] In the prior art, a fishing reel with a torque limiting device is known. For example, the torque limiting device disclosed in Patent Document 1 is used to limit the torque between the handle shaft and a gear supported on the handle shaft.

[0005] Patent Document 1: Japanese Patent Publication No. 5912371 Summary of the Invention
[0006] [The technical problem that the invention aims to solve]
[0007] Regarding this torque limiting device, it is desirable to improve its durability.
[0008] The technical problem to be solved by the present invention is to improve the durability of the torque limiting device in the fishing reel and the fishing reel itself.
[0009] [Technical solutions used to solve technical problems]
[0010] The torque limiting device for fishing reels according to this invention is used to limit the torque between a first rotating component and a second rotating component. The first rotating component is rotatably disposed on the reel body; the second rotating component is disposed on the outer periphery of the first rotating component in a manner rotatable about the axis of rotation of the first rotating component. The torque limiting device has an engaging recess, an engaging component, and a force-applying component. The engaging recess is formed on the inner circumferential surface of the second rotating component. The engaging component is disposed on the first rotating component in a manner retractable toward the second rotating component. The engaging component has a head capable of engaging with the engaging recess. The force-applying component applies force to the engaging component toward the second rotating component. The head of the engaging component has a straight portion at its tip, which extends linearly along the axis of rotation of the first rotating component.
[0011] In this torque limiting device for fishing reels, the head has a straight section at its tip, allowing the engaging member to make line contact with the engaging recess. This disperses stress compared to point contact between the engaging member and the engaging recess, thus improving the durability of both the engaging member and the engaging recess. Consequently, the durability of the torque limiting device is improved.
[0012] It can be that, in the engaging component, at least the head is made of resin. In this case, compared with the case where the engaging component makes point contact with the engaging recess, the durability of the engaging component and the engaging recess is improved. Therefore, at least a portion of the engaging component can be resinified, thereby enabling the weight reduction of the torque limiting device.
[0013] It can be that the head has a pair of inclined portions connected to the straight portion, and at least a portion of these inclined portions can contact the engaging recess. Alternatively, the pair of inclined portions can be formed to extend towards the rotation axis of the first rotating member as they approach the straight portion. In this case, both improved durability and weight reduction of the engaging member can be achieved.
[0014] Another technical solution of the present invention relates to a fishing reel having a reel body, a first rotating component, a second rotating component, and the aforementioned torque limiting device, wherein the first rotating component is rotatably disposed on the reel body; the second rotating component is disposed on the outer periphery of the first rotating component in a manner rotatable about the rotation axis of the first rotating component; and the torque limiting device is used to limit the torque between the first rotating component and the second rotating component.
[0015] In this fishing reel, because the head of the engaging component has a straight portion at its tip, the engaging component makes line contact with the engaging recess. Therefore, compared to the case where the engaging component makes point contact with the engaging recess, stress can be dispersed, thus improving the durability of both the engaging component and the engaging recess. As a result, the durability of the torque limiting device can be improved.
[0016] [Invention Effects]
[0017] According to the present invention, the durability of the torque limiting device in a fishing reel and in a fishing reel can be improved. Attached Figure Description

Detailed Implementation
[0029] like Figures 1 to 3 As shown, in one embodiment of the present invention, a fishing reel 100 has a reel body 2, a spool 3, a handle 4, and a spool drive mechanism 13 (see reference). Figure 3 The fishing reel 100 is an electric fishing reel that rotates the spool 3 by a motor 12 driven by electrical power supplied from an external power source. Furthermore, in the following description, the direction in which the spool shaft 10 and the drive shaft 30 extend (described later) is referred to as the axial direction. Additionally, the direction orthogonal to the axial direction is referred to as the radial direction.
[0030] The fishing reel body 2 has a frame 7, a first side cover 8a, and a second side cover 8b. The frame 7 has a first side plate 7a, a second side plate 7b, multiple connecting parts 7c, and a mechanism mounting plate 9.
[0031] The first side plate 7a is positioned on the right side, facing forward of the frame 7 (in the direction the fishing line is released). The second side plate 7b is positioned on the left side of the frame 7, axially spaced from the first side plate 7a. Multiple connecting portions 7c extend axially, connecting the first side plate 7a and the second side plate 7b. A mechanism mounting plate 9 is positioned between the first side plate 7a and the first side cover 8a. Various mechanisms are mounted on the mechanism mounting plate 9.
[0032] The first side cover 8a covers the right side of the first side panel 7a of the frame 7. The second side cover 8b covers the left side of the second side panel 7b of the frame 7.
[0033] like Figure 2 As shown, the spool 3 is rotatable relative to the fishing reel body 2 and is disposed between the first side plate 7a and the second side plate 7b. The spool 3 is supported by a spool shaft 10 extending axially inside the fishing reel body 2. The spool 3 is integrally rotatably mounted to the spool shaft 10. The spool shaft 10 is rotatably supported on the fishing reel body 2 by a pair of bearings 11a and 11b disposed on the fishing reel body 2. In this embodiment, the spool shaft 10 extends in the left-right direction.
[0034] The handle 4 is rotatable relative to the fishing reel body 2. The handle 4 is located on the first side cover 8a side of the fishing reel body 2.
[0035] The spool drive mechanism 13 transmits the rotation of the handle 4 and the motor 12 to the spool 3. For example... Figure 3 As shown, the winding drum drive mechanism 13 has a first rotary transmission mechanism 14 and a second rotary transmission mechanism 15.
[0036] The first rotational transmission mechanism 14 decelerates the rotation of the motor 12 and transmits it to the winding drum 3. In detail, the first rotational transmission mechanism 14 has a planetary gear mechanism (not shown), a first gear component 60, a second gear component 61, and a pinion 32 connected to the output shaft of the motor 12.
[0037] The rotation of motor 12 is transmitted to the first gear component 60 via a planetary gear mechanism. The second gear component 61 meshes with the first gear component 60. The second gear component 61 is an intermediate gear for transmitting the rotation of the first gear component 60 to the pinion 32, and meshes with the pinion 32.
[0038] The pinion 32 is rotatable about the axis of the spool shaft 10, which extends through the inner circumference. The pinion 32 is mounted on the fishing reel body 2 in a manner that allows it to move axially between a connected position and a disengaged position. The connected position is where the pinion 32 is connected to the spool shaft 10 in a manner that allows it to rotate integrally with the spool shaft 10; the disengaged position is where the connection between the pinion 32 and the spool shaft 10 is released. The pinion 32 engages with the clutch fork 41 (described later) and moves axially together with the clutch fork 41. The pinion 32 has an annular recess 32a for engaging with the clutch fork 41.
[0039] The second rotation transmission mechanism 15 transmits the rotation of the handle 4 to the spool 3 via the first rotation transmission mechanism 14. The second rotation transmission mechanism 15 has a drive shaft 30 (an example of the first rotating component), a drive gear 31, and a third gear component 62.
[0040] The drive shaft 30 is configured to rotate relative to the fishing reel body 2. The drive shaft 30 extends in the left-right direction. The rotation axis C of the drive shaft 30 is along... Figure 3 The direction of rotation of the drive shaft 30 extends orthogonally to the plane of the paper. In the following description, the direction in which the rotation axis C of the drive shaft 30 extends is referred to as the rotation axis direction. In this embodiment, the rotation axis direction is consistent with the axial direction. The handle 4 is rotatably connected to the drive shaft 30.
[0041] The drive shaft 30 is prevented from rotating in the opposite direction to the winding direction by a roller-type one-way clutch (not shown) mounted on the first side cover 8a. Furthermore, the drive shaft 30 is also prevented from rotating by a rotating member 52 and a claw member 54 capable of engaging with the rotating member 52 (see reference 54). Figure 4 The claw-type one-way clutch, which is composed of [missing information], is prohibited from rotating in the opposite direction to the winding direction.
[0042] The drive gear 31 is rotatably mounted on the drive shaft 30. The rotation of the drive shaft 30 is transmitted to the drive gear 31 via a known traction mechanism.
[0043] The third gear component 62 meshes with the drive gear 31 and is rotatably connected to the planet carrier of the planetary gear mechanism. Accordingly, the rotation of the third gear component 62 is transmitted to the pinion 32 through the planet carrier, the first gear component 60, and the second gear component 61.
[0044] Fishing reel 100 also has a clutch mechanism 16 (see reference). Figure 2 ) and clutch operating components 17 (see reference) Figure 3 Additionally, such as Figure 4 and Figure 5 As shown, the fishing reel 100 also has a clutch control mechanism 20, a clutch reset mechanism 22, and a limiting component 24.
[0045] The clutch mechanism 16 is a mechanism for transmitting the rotational force of the handle 4 to the spool 3 and for cutting off this transmission. The clutch mechanism 16 has the same structure as in the prior art and is disposed between the spool shaft 10 and the pinion 32. Figure 2 As shown, the clutch mechanism 16 has an engagement pin 16a and an engagement recess 16b.
[0046] When the clutch mechanism 16 is in the transmission state, that is, when the pinion 32 is in the engaged position, the engaging pin 16a engages with the engaging recess 16b, and the rotation of the pinion 32 is transmitted to the winding drum shaft 10. On the other hand, when the clutch mechanism 16 is in the disengaged state, that is, when the pinion 32 is in the disengaged position, the engaging pin 16a disengages from the engaging recess 16b, and the rotation of the pinion 32 is not transmitted to the winding drum shaft 10.
[0047] The clutch operating component 17 is located at the rear of the fishing reel body 2 and is supported on the fishing reel body 2 in a manner that allows it to move vertically. Figure 3 In this configuration, the clutch operating component 17 is movable between a first position indicated by a solid line and a second position indicated by a dashed line, and is subjected to force toward the first position.
[0048] like Figure 4 As shown, the clutch operating component 17 has a rotating part 18 and an operating part 19. The rotating part 18 is supported on the fishing reel body 2 in a manner rotatable about the axis of the spool shaft 10. The rotating part 18 has a ring part 18a, an insertion part 18b, a first spring hook part 18c, and a connecting part 18d. The ring part 18a is supported in a swingable manner on the outer peripheral surface of a first support part 9a provided on the mechanism mounting plate 9. The insertion part 18b passes through the operating part 19 axially and is integrally connected to the operating part 19.
[0049] The first spring hook portion 18c is formed to extend radially outward from the outer periphery of the ring portion 18a. One end of the first spring member 51, which applies force to the clutch operating member 17 toward the first position, is hooked onto the first spring hook portion 18c. The first spring member 51 is, for example, a coil spring. The other end of the first spring member 51 is hooked onto the outer side of the first side cover 8a side of the mechanism mounting plate 9.
[0050] The connecting portion 18d connects the ring portion 18a and the insertion portion 18b together. A support shaft 18e is provided on the connecting portion 18d, which supports the clutch pawl 44 of the clutch control mechanism 20, which will be described later.
[0051] The operating section 19 is the part operated by pressing the clutch operating component 17 by hand. The operating section 19 is substantially arranged parallel to the winding drum shaft 10. The operating section 19 can move along the first side plate 7a and the second side plate 7b via the first contact member 43a and the second contact member 43b.
[0052] The clutch control mechanism 20 alternately switches the clutch mechanism 16 between a transmission state and a disengagement state each time the clutch operating component 17 moves from the first position to the second position. Since the structure of the clutch control mechanism 20 is the same as that of the prior art, it will be described simply here.
[0053] The clutch control mechanism 20 has a clutch cam 40, a clutch fork 41, and a clutch pawl 44.
[0054] The clutch cam 40 rotates in only one direction each time the clutch operating component 17 moves from the first position to the second position. Specifically, the clutch cam 40 rotates in one direction each time the clutch operating component 17 moves from the first position to the second position. Figure 5 The rotation phase RP is specified by the rotation in the first direction R1 shown. The clutch cam 40 is rotatably mounted on the first support 9a of the mechanism mounting plate 9.
[0055] The clutch cam 40 has a plurality of ratchet teeth 40a and a plurality of cam portions 40b. The plurality of ratchet teeth 40a are arranged on the outer peripheral surface of the clutch cam 40 in a circumferentially spaced manner. The predetermined rotational phase RP is determined according to the number of ratchet teeth 40a. In this embodiment, there are 12 ratchet teeth 40a, and the predetermined rotational phase RP is 30 degrees.
[0056] The ratchet tooth 40a has a first ratchet tooth 40c and a second ratchet tooth 40d. The first ratchet tooth 40c and the second ratchet tooth 40d are alternately arranged at intervals in the circumferential direction.
[0057] The cam portion 40b is provided with a phase PS associated with a predetermined rotational phase RP, spaced apart in the circumferential direction. The cam portion 40b causes the clutch shift fork 41 to move axially each time the clutch operating member 17 moves from the first position to the second position.
[0058] The clutch shift fork 41 is configured to position the pinion 32 between an engaged position and a disengaged position. The clutch shift fork 41 is axially movable. Figure 4 The guide member 49 is fixed to the first support portion 9a of the mounting plate 9 shown. The clutch shift fork 41 is supported by two second spring members 42 mounted on the guide member 49, which exert force in an axial direction toward the clutch cam 40. The clutch shift fork 41 has an engagement portion 41a that engages with the annular recess 32a of the pinion 32.
[0059] The clutch pawl 44 is supported on the support shaft 18e of the rotating part 18 in a freely swinging manner. As the clutch operating member 17 moves from the first position to the second position, the clutch pawl 44 causes the clutch cam 40 to rotate a predetermined rotational phase RP in the first direction R1. Specifically, the clutch pawl 44 engages with either the first ratchet tooth 40c or the second ratchet tooth 40d of the ratchet tooth 40a, pressing the clutch cam 40 in the first direction R1. The clutch pawl 44 is subjected to force toward the ratchet tooth 40a by the third spring member 48 supported by the support shaft 18e of the rotating part 18.
[0060] The clutch reset mechanism 22 is a mechanism for restoring the clutch mechanism 16 to the transmission state by rotating the handle 4 when the clutch mechanism 16 is in the disengaged state. The clutch reset mechanism 22 has a rotating member 52 (an example of a second rotating member). The rotating member 52 is arranged on the outer periphery of the drive shaft 30 in a manner rotatable about the rotation axis C of the drive shaft 30. The rotating member 52 is supported on the drive shaft 30 and rotates in response to rotation of the handle 4. In this embodiment, the rotating member 52 is made of resin.
[0061] The rotating component 52 has multiple protrusions 52a and connecting holes 52b. The protrusions 52a are arranged at intervals in the circumferential direction. When the clutch mechanism 16 is in the disengaged state, the protrusions 52a engage with the first ratchet tooth 40c of the clutch cam 40 by the rotation of the handle 4, thereby causing the clutch cam 40 to rotate in the first direction R1.
[0062] The protrusion 52a is configured such that it does not engage with the second ratchet tooth 40d of the clutch cam 40. Specifically, the second ratchet tooth 40d is thinner in the radial direction than the first ratchet tooth 40c. Furthermore, when the clutch mechanism 16 is in the transmission state, the protrusion 52a is positioned close to the second ratchet tooth 40d. Therefore, even if the handle 4 is rotated, the protrusion 52a prevents the clutch cam 40 from rotating in the first direction R1.
[0063] Except for the engaging recess 72 described later, the connecting hole 52b is circular, and the drive shaft 30 passes through it axially.
[0064] When the clutch mechanism 16 is switched from the transmission state to the disengagement state by the movement of the clutch operating component 17, the limiting component 24 restricts the operation of the clutch reset mechanism 22.
[0065] Specifically, when the clutch mechanism 16 is in the transmission state, the clutch operating member 17 is moved from the first position to the second position. At this time, the clutch mechanism 16 is switched from the transmission state to the disengagement state by the rotation of the clutch cam 40. The limiting member 24 restricts the operation of the clutch reset mechanism 22 for at least a portion of the period from when the clutch mechanism 16 is switched from the transmission state to the disengagement state until the clutch operating member 17 returns to the second position. Furthermore, "at least a portion" means including the period when the clutch operating member 17 is in the second position.
[0066] like Figure 4 As shown, a limiting member 24 is provided on the rotating portion 18 of the clutch operating member 17. Specifically, the limiting member 24 extends axially in a plate-like shape from the annular portion 18a of the rotating portion 18. The limiting member 24 is integrally provided with the rotating portion 18. The limiting member 24 is formed, for example, by bending a portion of the rotating portion 18.
[0067] When the clutch mechanism 16 is switched from the transmission state to the disengagement state by the movement of the clutch operating member 17, the first ratchet tooth 40c of the clutch cam 40 interferes with the protrusion 52a of the rotating member 52. Specifically, the first ratchet tooth 40c of the clutch cam 40 interferes with the protrusion 52a of the rotating member 52 as the clutch operating member 17 moves from the first position to the second position. Figure 5 The solid line indicates the standby position, which is then rotated to the dashed line indicates the limiting position. Thus, the rotation of the rotating member 52 in the winding direction WD is limited by the limiting member 24, thereby preventing the clutch reset mechanism 22 from operating due to the rotation of the handle 4.
[0068] like Figure 5 and Figure 6 As shown, the fishing reel 100 also has a torque limiting device 70. The torque limiting device 70 is used to limit the torque transmitted between the drive shaft 30 and the rotating component 52. The torque limiting device 70 is configured to prevent damage to the limiting component 24 and the protrusion 52a when a large load is applied to the limiting component 24.
[0069] The torque limiting device 70 has an engaging recess 72, an engaging component 73, and a force-applying component 74.
[0070] A locking recess 72 is formed on the inner peripheral surface of the rotating member 52. The locking recess 72 is formed on the inner peripheral surface of the rotating member 52 in a radially outward recessed manner. The locking recess 72 is formed in the connecting hole 52b. In this embodiment, four locking recesses 72 are provided at intervals in the circumferential direction of the drive shaft 30.
[0071] The engaging recess 72 has a locking surface 72a and a bevel 72b. The locking surface 72a is formed along the top of a pair of engaging members 73. The locking surface 72a extends in the direction of rotation axis. The bevel 72b is configured to apply force to the rotating member 52 in the winding direction WD. When viewed from the axial direction of the drive shaft 30, the bevel 72b is inclined in a straight line and is formed such that its inner diameter gradually increases as it moves in the winding direction WD.
[0072] The engaging member 73 consists of a pair of pin members. The engaging member 73 is disposed on the drive shaft 30 in a retractable manner toward the rotating member 52. Specifically, the engaging member 73 is received in a retractable manner within a through hole 30a, which is formed radially through the drive shaft 30. The through hole 30a is formed at a position radially overlapping with the rotating member 52. Radial movement of the engaging member 73 is guided by the inner circumferential surface of the through hole 30a.
[0073] like Figures 6 to 9 As shown, the engaging member 73 has a head 73a that can engage with the engaging recess 72 and a shaft portion 73b with a diameter smaller than that of the head 73a.
[0074] In the engaging member 73, at least the head 73a is made of resin. In this embodiment, the entire engaging member 73 is made of resin.
[0075] The head 73a has a straight portion 73c and a pair of inclined portions 73d. The straight portion 73c is formed at the top of the head 73a. The straight portion 73c has a shape that is in line contact with the engaging recess 72 in the direction of rotation axis. Specifically, the straight portion 73c extends in a straight line along the direction of rotation axis. Extending in a straight line along the direction of rotation axis means that it also includes a shape that extends in a straight line in a slightly inclined manner relative to the direction of rotation axis. Therefore, the straight portion 73c may also extend in a straight line in a slightly inclined manner relative to the direction of rotation axis. The straight portion 73c is formed in a manner that spans the entire length of the head 73a in the direction of rotation axis. The straight portion 73c is in at least line contact with the engaging recess 72. In addition, the straight portion 73c may also be formed in a part of the head 73a in the direction of rotation axis.
[0076] A pair of inclined portions 73d are connected to the straight portion 73c. The pair of inclined portions 73d are formed on the side surface of the head 73a and extend substantially circumferentially from the straight portion 73c. The pair of inclined portions 73d extend radially along the rotation axis. The pair of inclined portions 73d are formed such that they extend in the rotation axis direction as they approach the straight portion 73c. At least a portion of the pair of inclined portions 73d can contact the engaging recess 72. In this embodiment, the portions of the pair of inclined portions 73d adjacent to the straight portion 73c contact the engaging recess 72.
[0077] By pressing the locking surface 72a with the head 73a, the rotating component 52 rotates together with the drive shaft 30. When a torque exceeding the allowable value is applied between the drive shaft 30 and the rotating component 52, the head 73a retracts within the through hole 30a, and the drive shaft 30 rotates relative to the rotating component 52. That is, when a torque exceeding the allowable value is applied between the drive shaft 30 and the rotating component 52, only the drive shaft 30 rotates.
[0078] The force-applying component 74 is housed in the through hole 30a. The force-applying component 74 applies force to the engaging component 73 toward the rotating component 52. The force-applying component 74 is, for example, a helical spring, which is mounted on the shaft portion 73b of the engaging component 73 in a compressed state.
[0079] In the torque limiting device 70 with the above-described structure, since the head 73a of the engaging member 73 has a straight portion 73c at its top, the engaging member 73 makes line contact with the engaging recess 72. Therefore, compared to the case where the engaging member 73 makes point contact with the engaging recess 72, stress can be dispersed, thus improving the durability of both the engaging member 73 and the engaging recess 72. As a result, the durability of the torque limiting device 70 can be improved.
[0080] In addition, since the engaging component 73 and the rotating component 52 are made of resin, the torque limiting device 70 can be made lighter compared to the case where the engaging component 73 and the rotating component 52 are made of metal.
[0081] <Other Implementation Methods>
[0082] The above describes one embodiment of the present invention, but the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the invention. In particular, the various embodiments and modifications described in this specification can be arbitrarily combined as needed.
[0083] (a) In the above embodiment, an electric fishing reel that drives the spool 3 by a motor 12 is described as a fishing reel for fishing, but the present invention can also be applied to fishing reels for fishing with manual reeling.
[0084] (b) In the above embodiment, the torque limiting device 70 is structured to limit the torque transmitted between the drive shaft 30 and the rotating component 52. However, the torque limiting device 70 can also, for example, limit the torque between the worm shaft of the winding mechanism that evenly winds the fishing line onto the spool 3 and the driven gear supported by the worm shaft. Additionally, the torque limiting device 70 can also be structured to limit the torque of the rotating component that transmits rotation to the reciprocating mechanism that reciprocates the spool of the spinning reel. Furthermore, the torque limiting device 70 can also limit the torque between the drive shaft 30 and other rotating components supported by the drive shaft 30. For example, it can also limit the torque between the rotating component that transmits rotation to the driven gear and the drive shaft 30. Additionally, it can also limit the torque between the spool shaft 10 and the rotating component supported by the spool shaft 10.
[0085] (c) In the above embodiment, the engaging member 73 is composed of a pair of pin members, but the engaging member 73 may also be composed of a single pin member, for example. The torque limiting device 70 only needs to have at least one engaging recess 72.
[0086] (d) In the above embodiments, the engaging member 73 and the rotating member 52 are made of resin, but at least one of the engaging member 73 and the rotating member may also be made of metal.
