Description

Technical Field

[0001] This disclosure relates to line tensioners. Background Technology

[0002] Japanese Patent Application Publication No. 2017-51179 (Patent Document 1) discloses a fishing line winding machine for feeding / receiving fishing line. The fishing line winding machine includes a shaft, a reel, a first abutting wheel, a second abutting wheel, two brake pads, a second brake base, and a buffer mechanism.

[0003] In the aforementioned fishing line reel, a one-way bearing for rotating the shaft in one direction is provided on the shaft. The reel is configured to slide on the shaft. A second brake base is provided on the shaft. A buffer mechanism is provided on the shaft, and a first brake base is provided in the buffer mechanism.

[0004] Patent document 1 discloses the following: by connecting the fishing line wound on the reel to the fishing reel and performing the feeding operation of the fishing reel, the fishing line can be wound back onto the fishing reel.

[0005] Furthermore, Patent Document 1 discloses the following: using a one-way bearing, when the line is fed into the fishing reel, the shaft does not move, and the first abutment wheel, the second abutment wheel, the brake pad, and the reel slide simultaneously. Therefore, damping force is generated at the second brake base and the first brake base, and tension can be applied to the line when the fishing reel feeds the fishing line in and out.

[0008] Patent Document 1: Japanese Patent Application Publication No. 2017-51179 Summary of the Invention

[0009] The problem the invention aims to solve

[0010] In the line winding machine disclosed in Patent Document 1, the frictional heat generated at the brake base is transferred to the spool (drum) on which the fishing line is wound, which may damage the line. In addition, when a strong damping force is generated at the brake base, the brake-related components are overheated, thereby reducing the damping force and potentially making it impossible to continuously apply the desired tension to the line.

[0011] This disclosure was made in view of the above-mentioned problems, and the object of this disclosure is to provide a line tensioner that can suppress line damage and continuously apply a desired tension to the line when feeding the line into a fishing reel.

[0012] Solution for solving the problem

[0013] The line tensioner disclosed herein applies tension to the line when it is fed into a fishing reel. The line tensioner includes a base, a shaft, a first braking part, a drum-shaped part, and a second braking part. The shaft is rotatably supported on the base. The first braking part is located axially adjacent to the base in the direction in which the shaft extends, and applies resistance to the rotation of the shaft. The drum-shaped part, viewed from the first braking part, is located on the opposite side of the base and engages with the shaft in a manner that allows it to rotate together with the shaft, enabling the line to be wound around it. The second braking part, viewed axially from the base, is located on the opposite side of the first braking part and adjacent to the base, and applies resistance to the rotation of the shaft.

[0014] The effects of the invention

[0015] According to this disclosure, it is possible to suppress damage to the wire and continuously apply the desired tension to the wire. Attached Figure Description

[0032] Hereinafter, a line tensioner according to an embodiment of the present disclosure will be described with reference to the accompanying drawings. In the following description of the embodiment, the same or equivalent parts in the drawings will be labeled with the same reference numerals, and their descriptions will not be repeated.

[0033] Figure 1 This is a schematic perspective view showing the state of a wire tensioner using one embodiment of the present disclosure. Figure 1 As shown, the line tensioner 1 of one embodiment of this disclosure can apply tension to the line 3 when it is fed from the spool 2 into the fishing reel 4. The detailed method of using the line tensioner 1 will be described below.

[0034] Figure 2 This is a side view showing the state of a line tensioner using one embodiment of the present disclosure. Figure 3 This is a top view showing the state of a line tensioner using one embodiment of the present disclosure. Figure 4 Observe from the direction of the arrow on line IV-IV Figure 2 A cross-sectional view obtained from the line tensioner.

[0035] like Figures 1 to 4 As shown, the wire tensioner 1 includes a base 10, a shaft 20, a first braking part 30, a drum-shaped part 40, a second braking part 50, a pressing part 60, a winding drum support part 70, a (first) auxiliary shaft part 81, a (first) auxiliary roller 82, a second auxiliary shaft part 83, a second auxiliary roller 84, a first support part 85, and a second support part 86.

[0036] Figure 5 This is a partial exploded 3D view of the base when viewed from one side. Figure 6 This is a partially exploded 3D view of the base when viewed from the other side. For example... Figures 4 to 6 As shown, the base 10 includes a main body 11, a first leg 12, a second leg 13, a base 14, a first mounting part 15, and a second mounting part 16.

[0037] The main body 11 includes a central cylindrical part 111, a first end edge part 112, a second end edge part 113, a first abutting part 114, a second abutting part 115, and a central bearing part 116.

[0038] A shaft portion 20 extends through the central cylindrical portion 111. A first end edge portion 112 is connected to one end of the central cylindrical portion 111 in the axial direction D1 extending from the shaft portion 20. The first end edge portion 112 has a generally cylindrical shape. The outer diameter of the first end edge portion 112 is smaller than the outer diameter of the central cylindrical portion 111. A plurality of protrusions 112a extending along the axial direction D1 are formed on the inner circumferential surface of the first end edge portion 112.

[0039] The second end edge 113 is connected to the other end of the central cylindrical portion 111 in the axial direction D1. The second end edge 113 has a generally cylindrical shape. The outer diameter of the second end edge 113 is smaller than the outer diameter of the central cylindrical portion 111. A plurality of protrusions 113a extending in the axial direction D1 are formed on the inner circumferential surface of the second end edge 113.

[0040] The first abutting portion 114 abuts against the first braking portion 30. The first abutting portion 114 has an annular shape. A shaft portion 20 extends through the inner circumference of the first abutting portion 114. A first end edge portion 112 is located on the outer circumference of the first abutting portion 114. The first abutting portion 114 is engaged with the first end edge portion 112 in the circumferential direction relative to the central axis of the shaft portion 20. Specifically, a plurality of notches 114a are formed on the outer circumferential surface of the first abutting portion 1144, and the plurality of notches 114a respectively engage with a plurality of protrusions 112a of the first end edge portion 112.

[0041] The second abutting portion 115 abuts against the second braking portion 50. The second abutting portion 115 has an annular shape. A shaft portion 20 extends through the inner circumference of the second abutting portion 115. A second end edge portion 113 is located on the outer circumference of the second abutting portion 115. The second abutting portion 115 is engaged with the second end edge portion 113 in the circumferential direction relative to the central axis of the shaft portion 20. Specifically, a plurality of notches 115a are formed on the outer circumferential surface of the second abutting portion 115, and the plurality of notches 115a respectively engage with the plurality of protrusions 113a of the second end edge portion 113.

[0042] The materials constituting the first abutting part 114 and the second abutting part 115 are not particularly limited. The first abutting part 114 and the second abutting part 115 may be made of metals such as aluminum.

[0043] The central bearing portion 116 is located on the inner circumference of the central cylindrical portion 111, the first end edge portion 112, and the second end edge portion 113. At the base portion 10 (main body portion 11), the central bearing portion 116 directly supports the shaft portion 20 so that it can rotate. Furthermore, the central bearing portion 116 is held in the axial direction D1 by the first abutment portion 114 and the second abutment portion 115.

[0044] The structure of the central bearing section 116 is not particularly limited. In this embodiment, the central bearing section 116 includes a cylindrical spacer 116a, a pair of rolling bearings 116b, a pair of seals 116c, and a plurality of flat washers 116d.

[0045] The inner circumferences of a pair of rolling bearings 116b contact both sides of the cylindrical spacer 116a in the axial direction D1. The pair of rolling bearings 116b also contact the central cylindrical portion 111 and the shaft portion 20. A pair of sealing portions 116c are located on opposite sides of the cylindrical spacer 116a when viewed from the pair of rolling bearings 116b. The pair of sealing portions 116c provide a liquid-tight seal between the central cylindrical portion 111 and the shaft portion 20. O-rings are provided on the inner and outer circumferential sides of the sealing portions 116c.

[0046] Multiple flat washers 116d are arranged axially along D1 on both sides of each sealing portion 116c, at least one, specifically two. The multiple flat washers 116d are made of metal such as stainless steel. Therefore, frictional heat generated when the sealing portion 116c slides in contact with at least one of the shaft portion 20 and the central cylindrical portion 111 due to the rotation of the shaft portion 20 is easily dissipated. Furthermore, the multiple flat washers 116d are separated from the central cylindrical portion 111, the first end edge 112, and the second end edge 113. This facilitates the application of grease to the central bearing portion 116, further suppressing the generation of frictional heat at the central bearing portion 116.

[0047] The first leg 12 and the second leg 13 extend from the main body 11. The first leg 12 and the second leg 13 extend radially and obliquely downward relative to the central axis of the shaft 20. When viewed from above, the first leg 12 and the second leg 13 extend in opposite directions. The base portion 14 has a plate-like shape and extends horizontally. The base portion 14 is connected to the first leg 12 and the second leg 13.

[0048] In this embodiment, the first mounting part 15 is disposed on the first leg 12, and the second mounting part 16 is disposed on the second leg 13 (see reference). Figure 5 and Figure 6 The base 10 also has a cover 17, in Figures 1 to 3In the example shown, it is installed in the first mounting part 15. A spool support 70 is installed in the second mounting part 16. Both the first mounting part 15 and the second mounting part 16 are configured to be able to install the spool support 70.

[0049] Figure 7 This is a three-dimensional diagram representing the shaft. For example... Figure 4 and Figure 7 As shown, the shaft 20 is rotatably supported on the base 10 (specifically the main body 11, more specifically the central bearing 116, and even more specifically a pair of rolling bearings 116b).

[0050] The shape of the shaft portion 20 is not particularly limited; specifically, it is formed by partially machining the hexagonal bolt. The shaft portion 20 has a cylindrical portion 21, a first locking portion 22, and a second locking portion 23.

[0051] The shaft portion 20 is supported on the base portion 10 in the cylindrical portion 21. The cylindrical portion 21 has a recessed portion 211 extending circumferentially along the central axis relative to the shaft portion 20. A sealing portion 116c (specifically, an O-ring provided on the inner circumferential side of the sealing portion 116c) is fitted into the recessed portion 211.

[0052] The first locking part 22 is located at one end of the shaft part 20 in the axial direction D1. The first locking part 22 is locked to the drum-shaped part 40 in the circumferential direction relative to the central axis of the shaft part 20. As a result, the drum-shaped part 40 rotates with the rotation of the shaft part 20. Specifically, the first locking part 22 has a plurality of corner portions 221 on its outer circumferential surface. The corner portions 221 are locked to the drum-shaped part 40 in the aforementioned circumferential direction.

[0053] The first locking portion 22 protrudes outward from the cylindrical portion 21 when viewed from the axial direction D1. The first locking portion 22 has a locking face 222 that abuts against the drum-shaped portion 40. The locking face 222 faces the base 10. Therefore, when the shaft portion 20 is pulled axially towards the base 10 when viewed from the drum-shaped portion 40, the locking face 222 presses the drum-shaped portion 40 towards the base 10. Specifically, the first locking portion 22 is the head of a hexagonal bolt.

[0054] The second locking part 23 is located at the other end of the shaft part 20 in the axial direction D1. The second locking part 23 is locked to the pressing part 60 in the circumferential direction relative to the central axis of the shaft part 20. As a result, the pressing part 60 rotates with the rotation of the shaft part 20. Specifically, the second locking part 23 has a pair of flat surfaces 231 extending along the axial direction D1. Each of the pair of flat surfaces 231 abuts against a portion of the pressing part 60 (described in detail later), thereby locking the second locking part 23 and the pressing part 60 in the circumferential direction.

[0055] Furthermore, the second locking part 23 also engages with the pressing part 60 in the axial direction D1. Specifically, the second locking part 23 has an external thread 232. By threading the external thread 232 into a portion of the pressing part 60 (described in detail later), the relative position of the pressing part 60 in the axial direction D1 is restricted. The external thread 232 is arranged in a manner that alternates with a pair of flat surfaces 231 in the circumferential direction relative to the central axis of the shaft part 20.

[0056] Figure 8 This is a partially exploded perspective view, primarily used to represent the cable tensioner of the first braking unit. (For example...) Figure 4 and Figure 8 As shown, the first braking part 30 is located adjacent to the base part 10 in the axial direction D1, and applies resistance to the rotation of the shaft part 20.

[0057] Specifically, the first braking part 30 applies resistance to the drum-shaped part 40, which rotates together with the shaft part 20, by being sandwiched between the base part 10 (more specifically, the first abutment part 114 of the main body part 11) and the drum-shaped part 40. As a result, resistance is applied to the rotation of the shaft part 20 (and the drum-shaped part 40).

[0058] The first braking part 30 includes at least one brake washer 31. The shaft portion 20 passes through the brake washer 31. In this embodiment, the first braking part 30 includes a plurality of brake washers 31 arranged in the axial direction D1. At least one brake washer 31 rubs against at least one of the base portion 10 and the drum-shaped portion 40, or the brake washers 31 rub against each other, thereby applying resistance to the drum-shaped portion 40 which rotates together with the shaft portion 20.

[0059] The first braking part 30 is exposed to the outside. Specifically, the circumferential surface of the brake washer 31 is exposed to the outside. From the viewpoint of wear resistance, the brake washer 31 is made of, for example, a fluoropolymer material such as Teflon (registered trademark).

[0060] like Figure 4 As shown, the drum-shaped portion 40, when viewed from the first braking portion 30, is located on the opposite side of the base 10 (specifically, the main body 11), and engages with the shaft portion 20 in a manner that allows it to rotate together with the shaft portion 20. Furthermore, the drum-shaped portion 40 allows the wire 3 to be wound around it (see reference). Figure 1 ).

[0061] Figure 9 This is an exploded three-dimensional view of the turbulent part when viewed from one side. Figure 10 This is an exploded three-dimensional view of the turret-like portion as observed from the other side. For example... Figure 4 , Figures 8-10 As shown, the drum-shaped portion 40 has a shell portion 41, a peripheral portion 42, a propeller portion 43, a cover portion 44, a fin portion 45, and a resin gasket 46.

[0062] The shell portion 41 has a first cylindrical portion 411, a second cylindrical portion 412, and a plurality of radial connecting portions 413.

[0063] A shaft portion 20 extends through the inner circumference of the first cylindrical portion 411, and a fin portion 45 is disposed thereon. The first cylindrical portion 411 is engaged with the first locking portion 22 of the shaft portion 20 in the circumferential direction of the axial direction D1 and the central axis of the shaft portion 20.

[0064] The first cylindrical portion 411 has a first locking portion 411a, a second locking portion 411b, and a third locking portion 411c. The first locking portion 411a abuts against the locking surface 222 of the first locking portion 22 on the side opposite to the side of the first braking portion 30.

[0065] The second locking part 411b is located on the side opposite to the first braking part 30 when viewed from the first locking part 411a. The inner circumferential surface of the second locking part 411b has a hexagonal shape when viewed from the axial direction D1, so as to lock with the plurality of corners 221 of the first locking part 22 in the circumferential direction.

[0066] The third locking part 411c is located on the side of the first braking part 30 when viewed from the first locking part 411a. A plurality of protrusions 411d extending along the axial direction D1 are formed on the inner circumferential surface of the third locking part 411c. A fin part 45 is disposed on the inner circumferential surface side of the third locking part 411c. The third locking part 411c is locked to the fin part 45 in the circumferential direction relative to the central axis of the shaft part 20 by means of the protrusions 411d.

[0067] The second cylindrical portion 412 is located on the outer periphery of the first cylindrical portion 411. The second cylindrical portion 412 extends along the axial direction D1 in such a way that it covers the outer periphery of the first braking portion 30 and the outer periphery of the first end edge portion 112 of the main body portion 11.

[0068] Multiple radial connecting portions 413 extend radially along the central axis of the shaft portion 20 and are respectively connected to the first cylindrical portion 411 and the second cylindrical portion 412. The multiple radial connecting portions 413 are separated from each other in the circumferential direction relative to the central axis of the shaft portion 20.

[0069] The circumferential face 42 is the part of the hanging line 3 (see reference). Figure 1 , Figure 3 The peripheral surface 42 is disposed on the outer peripheral surface of the second cylindrical portion 412. Preferably, the peripheral surface 42 is formed of a material with a high coefficient of friction to improve the friction with the line 3. The peripheral surface 42 is formed, for example, of a rubber polymer such as acrylonitrile-butadiene rubber (NBR).

[0070] The propeller portion 43, when viewed from the first cylindrical portion 411 and the radial connecting portion 413, is located on the side opposite to the first braking portion 30. The cover portion 44 is fitted into the housing portion 41 (specifically the second cylindrical portion 412) on the side opposite to the base portion 10 in a detachable manner. The cover portion 44 covers the propeller portion 43 and also engages with the propeller portion 43. Furthermore, the propeller portion 43 can engage with the cover portion 44 even if its orientation in the axial direction D1 is reversed. The cover portion 44 has a vent on its end face facing the axial direction D1.

[0071] The drum-shaped portion 40 rotates along with the shaft portion 20, thereby causing the propeller portion 43 to rotate. As a result, air flows towards the inner circumference of the second cylindrical portion 412 through the vents between the radial connecting portions 413 and the cover portion 44. This cools the heat generated by the first braking portion 30. Furthermore, it prevents the wire 3 wrapped around the drum-shaped portion 40 (circumferential portion 42) from being damaged by heat.

[0072] The fin portion 45 is made of metal and abuts against the first braking portion 30. The fin portion 45 has a plurality of recesses 451 formed on the side opposite to the shaft portion 20 (see reference). Figure 4 The plurality of recesses 451 are arranged in such a way that they form gaps with other constituent members of the drum-shaped portion 40 (specifically, the third locking portion 411c of the first cylindrical portion 411). The gaps may also be filled with grease to improve heat dissipation.

[0073] In this embodiment, the fin portion 45 includes a plurality of large-diameter washers 452 and a plurality of small-diameter washers 453 with an outer diameter smaller than that of the large-diameter washers 452. The shaft portion 20 passes through the plurality of large-diameter washers 452 and the plurality of small-diameter washers 453.

[0074] Multiple large-diameter washers 452 are respectively engaged with the first cylindrical portion 411 (specifically the third locking portion 411c) of the shell portion 41 in the circumferential direction relative to the central axis of the shaft portion 20. Therefore, the fin portion 45 rotates by the rotation of the shaft portion 20 and the drum-shaped portion 40. More specifically, multiple notches 452a are formed on the outer peripheral surface of the large-diameter washers 452, and the multiple notches 452a respectively engage with the multiple protrusions 411d of the third locking portion 411c. One of the multiple large-diameter washers 452 abuts against the first braking portion 30 (see reference). Figure 8 ).

[0075] Multiple small-diameter washers 453 are each arranged such that large-diameter washers 452 are adjacent to each other on both sides along the axial direction D1. Therefore, a recess 451 is formed by the end face of the large-diameter washer 452 along the axial direction D1 and the outer peripheral surface of the small-diameter washer 453. In addition, the structure for forming the recess 451 is not limited to the structure of this embodiment.

[0076] The materials used to make up the large-diameter washer 452 and the small-diameter washer 453 are not particularly limited, such as stainless steel or aluminum.

[0077] The resin gasket 46 protects the housing portion 41 from the pressure of the fin portion 45. The resin gasket 46 is made of, for example, a fluoropolymer material such as Teflon (registered trademark).

[0078] Figure 11 This is a partially exploded perspective view, primarily used to represent the cable tensioner of the second braking unit. (For example...) Figure 4 and Figure 11 As shown, the second brake part 50 is located on the opposite side of the first brake part 30 and adjacent to the base 10 when viewed from the base 10 in the axial direction D1, and applies resistance to the rotation of the shaft part 20.

[0079] Specifically, the second braking part 50 applies resistance to the pressing part 60, which rotates together with the shaft part 20, by being sandwiched between the base part 10 (more specifically, the second abutment part 115 of the main body part 11) and the pressing part 60. As a result, resistance is applied to the rotation of the shaft part 20 (and the pressing part 60).

[0080] The structure of the second braking unit 50 is not particularly limited, but in this embodiment it has the same structure as the first braking unit 30 (see reference 1). Figure 8 The second brake unit 50 has the same brake washer 51 as the brake washer 31 of the first brake unit 30. The drum-shaped portion 40 viewed from the first brake unit 30 corresponds to the pressing portion 60 viewed from the second brake unit 50. In addition, the second brake unit 50 is also exposed to the outside in the same way as the first brake unit 30.

[0081] like Figure 4 and Figure 11 As shown, the pressing part 60 is located on the opposite side of the base 10 in the axial direction D1 when viewed from the second braking part 50. Figure 12 This is an exploded three-dimensional view of the pressing part when viewed from one side. Figure 13 This is an exploded perspective view of the pressing part from the other side. For example... Figure 4 , Figures 11-13 As shown, the pressing part 60 has a circumferentially locked part 61, a second fin part 62, a plurality of resin gaskets 63, a pressing body part 64, and a fixing part 65.

[0082] The circumferential locking part 61 is configured to lock with the shaft part 20 in the circumferential direction relative to the central axis of the shaft part 20, and is capable of displacement relative to the shaft part 20 in the axial direction D1. The circumferential locking part 61 includes a holding part 611, a first extension 612, a second extension 613, and a third extension 614, each having a generally cylindrical shape.

[0083] Specifically, a pair of flat surfaces 611a extending along the axial direction D1 are formed on the inner peripheral surface of the gripping portion 611. The pair of flat surfaces 611a and the pair of flat surfaces 231 in the second locking portion 23 of the shaft portion 20 (see reference) Figure 7 The two parts are positioned opposite each other, thereby gripping the second locking part 23 with the holding part 611. Thus, the second locking part 23 and the holding part 611 are locked together in the aforementioned circumferential direction.

[0084] The first extension 612 extends axially D1 from the holding portion 611 toward the base 10. The second fin portion 62 and the resin gasket 63 are located on the inner circumferential surface of the first extension 612. A plurality of protrusions 612a extending axially D1 are formed on the inner circumferential surface of the first extension 612.

[0085] The second extension 613 extends axially D1 from the first extension 612 toward the base 10. The second extension 613 is located on the outer periphery of the second brake part 50 and the outer periphery of the second end edge 113 of the main body part 11.

[0086] The third extension 614 extends axially along D1 from the first extension 612 toward the side opposite to the base 10. The outer peripheral surface of the third extension 614 has a spur gear-shaped profile.

[0087] The second fin portion 62 has the same structure as the fin portion 45 of the drum-shaped portion 40. However, the second fin portion 62 has only one recess 621 corresponding to the recess 451 in the fin portion 45. The second fin portion 62 may also have multiple recesses 621. The recesses 621 are arranged in such a way that they form a gap with other constituent members of the pressing portion 60 (specifically, the first extension 612 of the circumferentially locked portion 61). Grease for improving heat dissipation may also be filled into this gap.

[0088] The second fin portion 62 has a large-diameter washer 622 and a small-diameter washer 623 that correspond to the large-diameter washer 452 and the small-diameter washer 453 in the fin portion 45, respectively. However, the second fin portion 62 may also have multiple small-diameter washers 623.

[0089] Each of the plurality of large-diameter washers 622 is engaged with the first extension 612 of the circumferentially locked portion 61 in the circumferential direction relative to the central axis of the shaft portion 20. Therefore, the second fin 62 rotates by the rotation of the shaft portion 20 and the pressing portion 60 (circumferentially locked portion 61). More specifically, a plurality of notches 622a are formed on the outer circumferential surface of the large-diameter washers 622, and the plurality of notches 622a respectively engage with the plurality of protrusions 612a of the first extension portion 612. One of the plurality of large-diameter washers 622 abuts against the second braking portion 50 (see reference). Figure 11 ).

[0090] Multiple resin washers 63 are arranged adjacent to both sides of the gripping portion 611 in the axial direction D1. The multiple resin washers 63 protect the gripping portion 611 from pressing pressure from the second fin portion 62 and the pressing body portion 64. The resin washers 63 can be made of the same components as the resin washers 46.

[0091] When viewed from the circumferential locking portion 61, the pressing body portion 64 is located on the side opposite to the body portion 11 of the base portion 10. The pressing body portion 64 has a first internal thread portion 641, an outer peripheral wall portion 642, a wall portion 643, a plurality of claw portions 644, and a first concave-convex portion 645.

[0092] The first internal thread portion 641 is threadedly engaged with the external thread portion 232 in the second locking portion 23 of the shaft portion 20 (see reference). Figure 4 , Figure 7 When the first internal thread portion 641 rotates in one direction relative to the shaft portion 20, the first internal thread portion 641 displaces toward the circumferentially locked portion 61 (holding portion 611). Then, the first internal thread portion 641 further rotates (tightens) by pressing the circumferentially locked portion 61 (holding portion 611) through the resin washer 63, thereby pressing the second braking portion 50 through the second fin portion 62 and the resin washer 63. In this way, the pressing portion 60 presses the second braking portion 50 in the axial direction D1. Furthermore, by further rotating the first internal thread portion 641 in one direction (tightening) or in another direction (loosening), the pressing portion 60 can adjust the pressing force.

[0093] Furthermore, by rotating (tightening) the first internal thread portion 641 (pressing body portion 64) relative to the shaft portion 20 in one direction, the first locking portion 22 of the shaft portion 20 is pulled toward the base portion 10 (see reference). Figure 4 (etc.). As a result, the drum-shaped portion 40 (the first locked portion 411a of the shell portion 41) that is locked with the first locking portion 22 is pulled toward the base portion 10 (main body portion 11), so the pressing force of the drum-shaped portion 40 on the first braking portion 30 increases. In this way, the pressing portion 60 is configured such that the pressing force of the drum-shaped portion 40 on the first braking portion 30 can also be adjusted by means of the first internal thread portion 641.

[0094] As described above, the pressing part 60 mainly engages with the shaft part 20 by means of the circumferential locking part 61, which can rotate together with the shaft part 20, and mainly uses the pressing body part 64 to press the second braking part 50 in the axial direction D1. Furthermore, the pressing part 60 is configured such that the magnitude of the resistance of the first braking part 30 and the second braking part 50 can be adjusted by changing the pressing force on the second braking part 50.

[0095] The outer peripheral wall portion 642 is located on the outer peripheral side of the first internal thread portion 641 relative to the central axis of the shaft portion 20. The wall portion 643 connects the first internal thread portion 641 to the outer peripheral wall portion 642. A plurality of claw portions 644 extend from the outer peripheral wall portion 642 toward the inner peripheral side. When viewed from the wall portion 643, the plurality of claw portions 644 are located on the side of the circumferentially locked portion 61.

[0096] Multiple claw portions 644 engage with the spur gear-shaped outer peripheral surface of the third extension 614. Here, when the first internal thread portion 641 is rotated relative to the shaft portion 20, the pressing body portion 64 (outer peripheral wall portion 642) is rotated relative to the circumferentially locked portion 61. During this rotation, the multiple claw portions 644 step over the spur gear of the third extension 614. As a result, the pressing portion 60 can cause the pressing force on the second braking portion 50 and the pressing force of the drum-shaped portion 40 on the first braking portion 30 to change stepwise. The first concave-convex portion 645 is arranged in the pressing body portion 64 facing the side opposite to the circumferentially locked portion 61.

[0097] The fixing part 65 is located on the side opposite to the circumferentially locked part 61 when viewed from the pressing body part 64. The fixing part 65 has a second internal thread part 651 and a second stepped part 652.

[0098] The second internal thread 651 is threadedly engaged with the external thread 232 in the second locking part 23 of the shaft part 20 (see reference). Figure 4 , Figure 7 By rotating the second internal thread portion 651 relative to the shaft portion 20 and the pressing body portion 64 to tighten the pressing body portion 64, loosening of the first internal thread portion 641 relative to the external thread portion 232 can be suppressed, similar to a double nut. Furthermore, regardless of which direction the shaft portion 20 rotates in the circumferential direction, changes in the pressing force of the drum-shaped portion 40 on the first braking portion 30 and the pressing force of the pressing portion 60 on the second braking portion 50 can be suppressed.

[0099] The second step portion 652 is configured to engage with the first concave-convex portion 645 of the pressing body portion 64 when the second internal thread portion 651 is tightened.

[0100] like Figures 1 to 3 As shown, the spool support 70 is connected to the base 10 and supports the spool 2 for feeding the wire 3. In this embodiment, the spool support 70 is mounted on the second mounting part 16, but it can also be detached from the second mounting part 16 and mounted on the first mounting part 15.

[0101] Figure 14 Observe from the direction of the arrow on line XIV-XIV Figure 2 A cross-sectional view obtained from the line tensioner. Figure 15 It is a partially exploded perspective view of the spool and spool support.

[0102] like Figures 1-3 , Figure 14 , Figure 15 As shown, the spool support 70 includes a support shaft 71, a spool brake 72, a first side support 73, a second side support 74, and an arm 75.

[0103] The support shaft 71 supports the winding drum 2 so that it can rotate through the through hole 2a. The support shaft 71 extends along the axial direction D1 of the shaft 20. The support shaft 71 is connected to the arm 75. When the arm 75 is mounted on the second mounting part 16 (see reference...) Figure 1 (etc.), the support shaft portion 71 is located on one side of the drum-shaped portion 40 in the orthogonal direction D2, which is orthogonal to the axial direction D1. In addition, the base portion 10 and the spool support portion 70 are configured such that when the arm portion 75 is mounted on the first mounting portion 15, the support shaft portion 71 is located on the other side of the drum-shaped portion 40 in the orthogonal direction D2.

[0104] The material constituting the support shaft portion 71 is not particularly limited, but it is preferred to be made of a material with high wear resistance. The support shaft portion 71 is, for example, a carbon shaft.

[0105] The winding drum braking part 72 has a generally annular shape and has a first insert part 721 and a first stop part 722 through which the support shaft part 71 passes.

[0106] The first insert portion 721 has a protrusion 721a, multiple cantilever beam portions 721b, and multiple wing portions 721c. The protrusion 721a protrudes to one side in the axial direction D1 and engages with the notch 2b formed in the through hole 2a of the spool 2. Thus, the spool braking portion 72 is configured to rotate together with the spool 2 by engaging with the spool 2 supported on the support shaft portion 71 in the circumferential direction.

[0107] Multiple cantilever beam portions 721b are arranged circumferentially along the central axis of the support shaft portion 71. The multiple cantilever beam portions 721b extend to one side along the axial direction D1. Multiple wing portions 721c are arranged circumferentially along the central axis of the support shaft portion 71. The multiple wing portions 721c extend axially at an angle relative to the central axis of the support shaft portion 71 on the other side along the axial direction D1.

[0108] Multiple cantilever beam portions 721b of the first insertion portion 721 are embedded in the first stop portion 722. As a result, the first stop portion 722 presses down on the multiple cantilever beam portions 721b from the outer periphery, causing the top ends of the cantilever beam portions 721b to move towards the support shaft portion 71, thus pressing down on the support shaft portion 71 from the outer periphery. In this way, the drum braking portion 72 is configured to apply resistance to the rotation of the drum 2 by utilizing the friction generated with the support shaft portion 71 when rotating together with the drum 2.

[0109] Furthermore, when the first insert portion 721 is not inserted into the first stop portion 722, the cantilever beam portion 721b does not press against the support shaft portion 71. As a result, the drum brake portion 72 is configured to allow for easy repositioning of the support shaft portion 71 together with the drum 2.

[0110] The first side support portion 73 is provided on the outer peripheral surface 711 of the support shaft portion 71, and supports the spool 2 supported by the support shaft portion 71 from the side opposite to the spool brake portion 72 side.

[0111] The first side support portion 73 has a second insert portion 731, a second stop portion 732, and a first brake diaphragm 733. The second insert portion 731 and the second stop portion 732 have the same structure as the first insert portion 721 and the first stop portion 722, respectively.

[0112] The first braking diaphragm 733 is held by the spool 2 and the multiple wings 731c of the second insert 731. As a result, a smaller resistance can be applied to the spool 2, which rotates relative to the support shaft 71.

[0113] The second side support 74 is provided on the outer peripheral surface 711 of the support shaft 71, and supports the winding drum brake 72 from the side opposite to the winding drum 2.

[0114] The second side support portion 74 has a third insert portion 741, a third stop portion 742, and a second brake diaphragm 743. The third insert portion 741 and the third stop portion 742 have the same structure as the first insert portion 721 and the first stop portion 722, respectively.

[0115] The second braking diaphragm 743 is held by a plurality of wings 721c of the first insert 721 and a plurality of wings 741c of the third insert 741. As a result, a relatively small amount of resistance can be applied to the winding drum braking part 72, which rotates together with the winding drum 2.

[0116] like Figures 1 to 4 As shown, the (first) secondary shaft portion 81 is supported on the base 10, arranged with the drum-shaped portion 40, and extends along the axial direction D1. When viewed from the axial direction D1, the secondary shaft portion 81 is located obliquely below the drum-shaped portion 40. Specifically, the secondary shaft portion 81 extends from the first leg portion 12 along the axial direction D1 and is detachably fixed to the first leg portion 12.

[0117] (1) The auxiliary roller 82 is supported so as to be rotatable about the auxiliary shaft portion 81 as a central axis. The auxiliary roller 82 has an outer peripheral surface 821. At least one groove portion 822 extending along the rotation direction of the auxiliary roller 82 is formed on the outer peripheral surface 821. In this embodiment, a plurality of groove portions 822 arranged in the axial direction D1 are formed on the outer peripheral surface 821. When viewed from above, the plurality of groove portions 822 are located in a position arranged in the orthogonal direction D2 to the peripheral surface portion 42 of the drum-shaped portion 40 (see reference). Figure 3 ).

[0118] Alternatively, a groove may not be formed on the outer peripheral surface 821 of the auxiliary roller 82. Furthermore, the auxiliary shaft portion 81 may be inclined relative to the axial direction D1, gradually moving away from the drum-shaped portion 40 as it moves from the base 10 towards the tip of the auxiliary shaft portion 81. Even without a groove formed on the auxiliary roller 82, by inclining the auxiliary shaft portion 81 as described above, when the thread 3 is wound around the auxiliary roller 82, the extending direction of the thread 3 on the auxiliary roller 82 is also offset in the axial direction D1. Therefore, by winding the thread 3 around the auxiliary roller 82, overlap of the thread 3 on the peripheral surface 42 is prevented when the thread 3 is wound around the drum-shaped portion 40 at least once.

[0119] Figure 16 Observe from the direction of the arrow on line XVI-XVI Figure 2 A cross-sectional view obtained from a wire tensioner. For example... Figures 1-3 , Figure 16 As shown, the second auxiliary shaft portion 83 is supported on the base 10, arranged with the drum-shaped portion 40, and extends along the axial direction D1. The second auxiliary shaft portion 83 is located obliquely below the drum-shaped portion when viewed from the axial direction D1. Specifically, the second auxiliary shaft portion 83 extends from the second leg portion 13 along the axial direction D1 and is detachably fixed to the second leg portion 13. The auxiliary shaft portion 81 and the second auxiliary shaft portion 83 are configured to be interchangeable in their mounting positions.

[0120] The second auxiliary roller 84 is supported so as to be able to rotate about the second auxiliary shaft 83 as a central axis. The second auxiliary roller 84 has an outer peripheral surface 841. A groove 842 extending along the rotation direction of the second auxiliary roller 84 is formed on the outer peripheral surface 841. When viewed from above, the groove 842 is located in a position orthogonal to the peripheral surface 42 of the drum-shaped portion 40 in the direction D2 (see reference). Figure 3 Furthermore, when viewed from above, the groove 842 is located on the side of the pressing part 60 in the axial direction D1, which is closer to any of the multiple grooves 822 of the auxiliary roller 82.

[0121] Furthermore, the second sub-shaft portion 83 can also be tilted relative to the axial direction D1 as it gradually moves away from the drum-shaped portion 40 from the base 10 toward the top of the second sub-shaft portion 83. By tilting the second sub-shaft portion 83 as described above, when the thread 3 is hooked onto the second sub-roller 84, the extending direction of the thread 3 on the second sub-roller 84 is offset in the axial direction D1. Therefore, by hooking the thread 3 onto the second sub-roller 84, the overlap of the thread 3 on the peripheral surface 42 when the thread 3 is wound around the drum-shaped portion 40 is prevented. In addition, the sub-shaft portion 81 and the second sub-shaft portion 83 can both be tilted as described above, or only one of them can be tilted as described above.

[0122] like Figures 1-4 As shown, the first support portion 85 is located on the opposite side of the drum-shaped portion 40 when viewed from the auxiliary roller 82. The first support portion 85 is configured to be disposed along the outer peripheral surface 821 of the auxiliary roller 82. Furthermore, the first support portion 85 is configured to cover the plurality of grooves 822 of the auxiliary roller 82.

[0123] The first support portion 85 includes a first sliding portion 851, a first support shaft portion 852, and a first support roller 853. The first sliding portion 851 is configured to engage with the secondary shaft portion 81 and is slidable in the direction in which the secondary roller 82 and the first support roller 853 are arranged. The first support shaft portion 852 extends axially D1 from the first sliding portion 851. The first support roller 853 is supported so that it can rotate about the first support shaft portion 852 as a central axis. By sliding through the first sliding portion 851, the first support roller 853 can contact or separate from the outer peripheral surface 821 of the secondary roller 82 in a manner that covers a plurality of grooves 822. In addition, the first support portion 85 can also be detached from the base 10 together with the secondary shaft portion 81.

[0124] like Figures 1-3 as well as Figure 16 As shown, the second support portion 86 is located on the opposite side of the drum-shaped portion 40 when viewed from the second auxiliary roller 84. The second support portion 86 is configured to be disposed along the outer peripheral surface 841 of the second auxiliary roller 84. Furthermore, the second support portion 86 is configured to cover the groove portion 842 of the second auxiliary roller 84.

[0125] The second support portion 86 includes a second sliding portion 861, a second support shaft portion 862, and a second support roller 863. The second sliding portion 861 is configured to engage with the second auxiliary shaft portion 83 and is slidable in the direction in which the second auxiliary roller 84 and the second support roller 863 are arranged. The second support shaft portion 862 extends axially D1 from the second sliding portion 861. The second support roller 863 is supported so that it can rotate about the second support shaft portion 862 as a central axis. By sliding through the second sliding portion 861, the second support roller 863 can contact or separate from the outer peripheral surface 841 of the second auxiliary roller 84 in a manner that covers the groove portion 842. In addition, the second support portion 86 can also be detached from the base 10 together with the second auxiliary shaft portion 83.

[0126] The following is for reference Figures 1-3 The method of using the wire tensioner 1 will be explained. First, the spool support 70 is installed on either the first mounting part 15 or the second mounting part 16. Here, as shown in the figures, the state in which the spool support 70 is installed on the second mounting part 16 will be explained. In addition, the second auxiliary shaft part 83, the second auxiliary roller 84, and the second support part 86 are arranged in the orthogonal direction D2 between the drum-shaped part 40 and the support shaft part 71 (and the installed spool 2). The auxiliary shaft part 81, the auxiliary roller 82, and the first support part 85 are arranged in the orthogonal direction D2 on the side opposite to the support shaft part 71 when viewed from the drum-shaped part 40.

[0127] Next, the spool 2 is installed on the spool support 70, and the wire 3 is fed out from the spool 2 while rotating it. The fed wire 3 passes between the second auxiliary roller 84 and the second support roller 863 and is hooked into the groove 842 of the second auxiliary roller 84. Then, the wire 3 is wound around the circumference 42 of the drum-shaped portion 40 in a manner that is approximately one lap around it.

[0128] The thread 3, which is wound around the peripheral portion 42 in a manner that is approximately one lap around the periphery 42, further passes between the auxiliary roller 82 and the first support roller 853, and hooks onto one of the plurality of grooves 822 of the auxiliary roller 82. Then, the thread 3 is wound around the peripheral portion 42 of the drum-shaped portion 40 again in a manner that is approximately one lap around the periphery 42.

[0129] The line 3, wound approximately once more around the circumferential section 42, passes between the auxiliary roller 82 and the first support roller 853, and hooks onto another of the plurality of grooves 822 of the auxiliary roller 82. Then, the line 3 is connected to the fishing reel 4. Alternatively, if the line 3 is coated with lubricant, it may be further wound around the circumferential section 42 and the auxiliary roller 82 once more.

[0130] When the fishing line 3, connected to the fishing reel 4 as described above, is fed into the fishing reel 4, a rotational force is applied to the drum-shaped portion 40 by the frictional force (preferably static friction) between the line 3 and the peripheral surface 42 of the drum-shaped portion 40. This also applies a rotational force to the shaft portion 20 and the pressing portion 60. Furthermore, the first braking portion 30 and the second braking portion 50 described above provide resistance to this rotational force. As a result, tension is applied to the portion of the line 3 from the drum-shaped portion 40 to the fishing reel 4 during the feeding of the line 3. In this way, the line 3 can be fed into the fishing reel 4 while tension is applied.

[0131] Furthermore, the auxiliary rollers 82 and 84 rotate smoothly due to friction with the line 3 being fed in, thus suppressing friction between the line 3 and these rollers. In addition, since the spool 2 is braked with a relatively small force, the deflection of the line 3 is suppressed during feeding of the line 3 into the fishing reel 4, and the spool 2 rotates, thereby feeding the line 3 out.

[0132] As described above, in the wire tensioner 1 of one embodiment of this disclosure, the first braking part 30 is located adjacent to the base 10 in the axial direction D1 of the shaft 20, and applies resistance to the rotation of the shaft 20. The drum-shaped part 40 is located on the opposite side of the base 10 when viewed from the first braking part 30, and engages with the shaft 20 in a manner that allows it to rotate together with the rotation of the shaft 20. The drum-shaped part 40 can be used to wind the wire 3. The second braking part 50 is located on the opposite side of the first braking part 30 and adjacent to the base 10 in the axial direction D1 when viewed from the base 10, and applies resistance to the rotation of the shaft 20.

[0133] As described above, the second braking part 50, one of the plurality of braking parts that apply resistance to the rotation of the shaft 20, is located further away from the base 10 when viewed from the drum-shaped part 40. Therefore, the frictional heat generated near the drum-shaped part 40 can be reduced. Furthermore, the heat transferred to the wire 3 wound around the drum-shaped part 40 can be reduced, and damage to the wire 3 during feeding can be suppressed. In addition, since the frictional heat generated in each braking part can be reduced, overheating of braking-related components is suppressed at each braking point, and the reduction in resistance is also suppressed. Furthermore, the desired tension can be continuously applied to the wire 3 during feeding.

[0134] Furthermore, the first braking part 30 and the second braking part 50 are exposed to the outside.

[0135] According to the above structure, the frictional heat generated in the first braking part 30 and the second braking part 50 is easily dissipated to the outside of the cable tensioner 1. Therefore, it further suppresses the overheating of braking-related components and further suppresses the reduction of resistance.

[0136] Furthermore, the line tensioner 1 also includes a pressing part 60. The pressing part 60 is located on the opposite side of the base 10 in the axial direction D1 when viewed from the second brake part 50, and engages with the shaft 20 in a manner that allows it to rotate with the shaft 20, pressing the second brake part 50 in the axial direction D1. The first brake part 30, by being sandwiched between the base 10 and the drum-shaped part 40, applies resistance to the drum-shaped part 40, which rotates with the shaft 20. The second brake part 50, by being sandwiched between the base 10 and the pressing part 60, applies resistance to the pressing part 60, which rotates with the shaft 20. The pressing part 60 is configured such that by changing the pressing force applied to the second brake part 50, the magnitude of the resistance of the first brake part 30 and the second brake part 50 can be adjusted.

[0137] According to the above structure, the pressing part 60, located on the side opposite to the drum-shaped part 40 when viewed from the base 10, is configured to adjust the resistance, so that the user can hold the drum-shaped part 40 with one hand and adjust the resistance of the pressing part 60 with the other hand, making the operation of the line tensioner 1 easier.

[0138] Furthermore, the drum-shaped portion 40 has a metal fin portion 45 that abuts against the first braking portion 30. The fin portion 45 has a plurality of recesses 451 formed on the side opposite to the shaft portion 20.

[0139] According to the above structure, the surface area of ​​the fin portion 45 is increased due to the multiple recesses 451, and the frictional heat generated in the first braking portion 30 is easily dissipated from the first braking portion 30 via the fin portion 45. Therefore, overheating of the first braking portion 30 is further suppressed, and the reduction in drag is also further suppressed. In addition, the possibility of heat dissipated from the fin portion 45 being transferred to the line 3 via the drum-shaped portion 40 is also taken into consideration, but by dispersing the portion of the braking portion as described above, the heat of friction generated in the first braking portion 30 is suppressed to a certain extent. Therefore, both the reduction in drag of the first braking portion 30 and the reduction in heat transferred to the line 3 are achieved.

[0140] Furthermore, the wire tensioner 1 also includes a spool support 70. The spool support 70 is connected to the base 10 and supports the spool 2 for feeding the wire 3. The spool support 70 has a support shaft 71 and a spool brake 72. The support shaft 71 supports the spool 2 so that it can rotate through a through hole 2a. The spool brake 72 can rotate with the spool 2 by engaging with the spool 2 supported on the support shaft 71 in the circumferential direction, and applies resistance to the rotation of the spool 2 by friction with the support shaft 71 generated when rotating with the spool 2.

[0141] According to the above structure, the line 3 delivered from the spool 2 can be stably fed into the fishing reel 4 via the drum-shaped portion 40. Furthermore, by friction with the support shaft portion 71, the spool 2 is braked with relatively little resistance, thereby preventing the spool 2 from spinning freely when the line 3 is delivered, and preventing the line 3 wound on the spool 2 from tangling with each other.

[0142] Furthermore, the spool support 70 also includes a first side support 73 and a second side support 74. The first side support 73 is provided on the outer peripheral surface 711 of the support shaft 71, and supports the spool 2 supported by the support shaft 71 from the side opposite to the spool brake 72 side. The second side support 74 is provided on the outer peripheral surface 711 of the support shaft 71, and supports the spool brake 72 from the side opposite to the spool 2 side.

[0143] According to the above structure, it is possible to suppress the position of the supported spool 2 from shifting axially in the support shaft portion 71.

[0144] Furthermore, in the online tensioner 1, the support shaft portion 71 supports the spool 2 so that it can rotate through a through hole 2a passing through the spool 2. The support shaft portion 71 extends along the axial direction D1 of the shaft portion 20.

[0145] According to the above structure, the support shaft portion 71 extends along the axial direction D1 of the shaft portion 20, thereby preventing the wire 3 from getting caught on the winding drum 2 when the wire 3 fed from the winding drum 2 deflects, and also preventing the wire 3 from deflecting on the peripheral surface 42. Therefore, the desired tension can be applied to the wire 3 more stably and continuously.

[0146] Furthermore, the wire tensioner 1 also includes a secondary shaft portion 81 and a secondary roller 82. The secondary shaft portion 81 is supported on the base 10, arranged with the drum-shaped portion 40, and extends along the axial direction D1. The secondary roller 82 is supported so as to be able to rotate about the secondary shaft portion 81 as a central axis. The secondary roller 82 has an outer peripheral surface. A plurality of grooves 822 extending along the rotation direction of the secondary roller 82 are formed on the outer peripheral surface 821.

[0147] According to the above structure, when the thread 3 is wound multiple times around the drum-shaped portion 40, the thread 3 is wound in such a way that it is wound together around the drum-shaped portion 40 and the auxiliary roller 82. Furthermore, each time it is wound around the auxiliary roller 82, it can be wound around different grooves 822 among the multiple grooves 822 of the auxiliary roller 82. Therefore, even when the thread 3 is wound multiple times around the drum-shaped portion 40, it is possible to prevent the threads 3 from overlapping on the drum-shaped portion 40.
