Description

Technical Field

[0001] The present invention relates to a double-bearing type winding reel equipped with a magnetic braking device that applies braking force to the drum to suppress backlash. Background Technology

[0002] Regarding double-bearing reels used in fishing, when the fishing line wound on the spool is released from the spool, if the rotational speed of the spool exceeds the release speed of the fishing line, the fishing line may become entangled inside the spool, resulting in backlash.

[0003] To suppress this recoil, the double-bearing type reel is equipped with a braking device that applies braking force to the drum as it rotates due to the release of fishing line. As such a braking device, for example, a magnetic braking device is disclosed in Patent Documents 1 and 2. Furthermore, the magnetic braking device is also referred to as an electromagnetic induction braking device or a magnetic braking device.

[0004] In a magnetic braking device, a basically conductive rotating body is inserted into the magnetic field space while rotating together with the rotating drum. This causes an electromagnetic force to act on the rotating body in the opposite direction of rotation, thereby giving the drum a braking force.

[0005] The magnetic field space is located at one end of the reel shaft. The rotating body is fixed to the top of a generally cylindrical moving part into which the reel shaft is inserted, with the top of the rotating body's peripheral wall facing the magnetic space side. The moving part slides along the axis of the reel shaft toward the magnetic space side, thereby increasing the insertion depth of the rotating body into the magnetic field space.

[0006] Furthermore, a guide groove extending along the axial direction of the drum shaft is formed in the moving part, and a small-diameter cylindrical metal pin is provided on the drum shaft protruding outward in a radial direction. Moreover, the pin engages within the guide groove, allowing the moving part to rotate integrally with the drum. Furthermore, the pin passes through the guide groove, enabling the moving part to slide along the axial direction of the drum shaft. (For example, refer to paragraph

[0026] of Patent Document 1.) Figure 2-4 And referring to paragraph

[0016] of Patent Document 2, Figure 2-7 ).

[0007] The moving part is propelled towards the opposite side of the magnetic field space by the force applied by the compression coil spring. The moving part resists the force applied by the compression coil spring and moves towards the magnetic field space, thereby inserting the rotating body into the magnetic field space. The braking force applied to the drum is controlled by increasing or decreasing the insertion depth of the rotating body into the magnetic field space.

[0008] In order to make the insertion amount of the rotating body into the magnetic field space increase or decrease accordingly with the rotation speed of the drum, the magnetic braking device is configured as follows.

[0009] That is, a centrifugal collar is mounted on the moving part. The centrifugal collar is provided on the moving part in a direction away from the drum axis by utilizing the centrifugal force acting on the centrifugal collar as the drum rotates. On the other hand, a guide surface is formed on the surface of the drum (or, in detail, the outer surface of the drum flange) to guide the centrifugal collar toward the magnetic field space side when it moves in the direction away from the drum axis. Therefore, the centrifugal collar, which moves in the direction away from the drum axis due to centrifugal force, is guided toward the magnetic field space side by sliding along the guide surface of the drum. As a result, the moving part slides toward the magnetic field space side against the applied force of the compression coil spring, that is, the rotating body moves in a direction that increases the amount of insertion into the magnetic field space.

[0010] If the rotational speed of the drum increases, the centrifugal force acting on the centrifugal collar also increases. Therefore, the force required for the moving part to move towards the magnetic field space against the force applied by the compression coil spring increases, and the insertion depth of the rotating body into the magnetic field space increases. Conversely, if the rotational speed of the drum decreases, the centrifugal force acting on the centrifugal collar also decreases. Therefore, the force required for the moving part to move towards the magnetic field space against the force applied by the compression coil spring decreases, and the insertion depth of the rotating body into the magnetic field space decreases. Thus, the insertion depth of the rotating body into the magnetic field space increases or decreases accordingly with the rotational speed of the drum.

[0011] Prior art literature Patent Document 1: Japanese Patent Application Publication No. 2005-52062; Patent Document 2: Japanese Patent Application Publication No. 2005-58171. Summary of the Invention

[0012] [The problem the invention aims to solve] In the aforementioned existing magnetic braking device, the centrifugal collar slides along the guide surface of the drum. Therefore, if small foreign objects (floating matter in water (e.g., algae, dust), dried residues in water (e.g., salt particles), suspended matter in the air (e.g., fine sand, dust), etc.) adhere to and accumulate on the guide surface due to long-term use of the winding reel, the centrifugal collar may sometimes be unable to slide smoothly along the guide surface, hindering the adjustment of the amount of the rotating body inserted into the magnetic field space. If the adjustment of the amount of the rotating body inserted is hindered, it becomes impossible to properly control the braking force applied to the drum.

[0013] The present invention was made in view of the above-mentioned technical background, and the object of the present invention is to provide a double-bearing type winding wheel with a magnetic braking device that can control the braking force applied to the drum without being affected by the surface condition of the drum.

[0014] [Solutions for solving the problem] The present invention provides the following solution.

[0015] 1) A double-bearing type reel, comprising a drum that rotates integrally with the drum shaft around which the reel shaft is centered, and a magnetic braking device that applies braking force to the drum when the drum rotates due to the release of fishing line, wherein, The aforementioned magnetic braking device comprises: a magnetic field space formed at one end of the aforementioned spool shaft along its axial direction; a moving member having a conductive rotating body and movable along the axial direction of the aforementioned spool shaft; a holding device that holds the aforementioned moving member rotatably together with the aforementioned spool shaft; and a control device that controls the braking force applied to the aforementioned spool shaft by increasing or decreasing the insertion amount of the aforementioned rotating body into the aforementioned magnetic field space. The aforementioned control device includes: a force-applying member that applies force to the aforementioned moving member in a direction that reduces the aforementioned insertion amount of the aforementioned rotating body; a swing member having a centrifugal hammer portion formed at one end and a push arm portion formed at the other end; and a support member that supports the aforementioned swing member in a swingable manner with a swing axis disposed between the aforementioned centrifugal hammer portion and the aforementioned push arm portion of the aforementioned swing member as the center. Furthermore, the aforementioned support component is disposed on the aforementioned drum in such a manner that the aforementioned swing member rotates integrally with the aforementioned drum. The centrifugal hammer of the aforementioned swing member utilizes the centrifugal force acting on it as the aforementioned drum rotates, causing it to swing about the aforementioned swing axis and move in a direction away from the aforementioned drum axis. The centrifugal hammer of the aforementioned swing member swings and moves in a direction away from the aforementioned drum shaft using the aforementioned centrifugal force, thereby causing the aforementioned pushing arm of the aforementioned swing member to push and move the aforementioned moving member against the applied force of the aforementioned force-applying member in a direction that increases the aforementioned insertion amount of the aforementioned rotating body.

[0016] 2) According to the double-bearing type winding reel described in item 1 above, The aforementioned movable component is formed in a generally cylindrical shape and is disposed on the aforementioned drum shaft with the aforementioned drum shaft inserted through its inner side, and is capable of sliding along the axial direction of the aforementioned drum shaft. The aforementioned moving component has an inclined surface that slopes toward the magnetic field space in a direction outside the radius of the aforementioned moving component. The pushing arm of the aforementioned swing member pushes the aforementioned inclined surface of the aforementioned moving member in a direction that approaches the aforementioned drum shaft, thereby causing the aforementioned moving member to slide along the axial direction of the aforementioned drum shaft in a direction that increases the aforementioned insertion amount of the rotating body, resisting the applied force of the aforementioned force-applying member.

[0017] 3) The double-bearing type winding reel as described in item 1 or 2 above, The aforementioned movable component is formed in a generally cylindrical shape and is disposed on the aforementioned drum shaft with the aforementioned drum shaft inserted through its inner side, and is capable of sliding along the axial direction of the aforementioned drum shaft. The aforementioned retaining device has a pair of retaining plates formed opposite to each other on both ends of the aforementioned moving member in the axial direction of the aforementioned swing axis of the aforementioned swing member. In the aforementioned holding device, with the side of the aforementioned swing member disposed between the aforementioned two holding plates abutting against the inner surface of the aforementioned holding plate, the aforementioned swing member rotates integrally with the aforementioned drum, thereby causing the aforementioned moving member to rotate integrally with the aforementioned drum.

[0018] 4) The double-bearing type winding reel as described in item 3 above, A convex spherical swing shaft protrusion is formed at both ends of the swing shaft along the axial direction on both sides of the aforementioned swing member. When the aforementioned swing member rotates integrally with the aforementioned drum, the aforementioned swing shaft protrusion abuts against the aforementioned inner surface of the aforementioned retaining plate in a point contact state.

[0019] 5) The double-bearing type winding reel as described in item 3 or 4 above, The aforementioned swinging component and the aforementioned retaining plate are both made of resin.

[0020] 6) The double-bearing type winding reel according to any one of items 3-5 above, The aforementioned swinging member and the aforementioned holding device are disposed at multiple locations in the circumferential direction of the aforementioned moving member.

[0021] [The effects of the invention] The present invention achieves the following effects.

[0022] In item 1 above, in the controller of the magnetic brake device, the centrifugal hammer of the oscillating member oscillates and moves about the oscillation axis in a direction away from the drum axis, utilizing the centrifugal force acting on the centrifugal hammer along with the rotation of the drum. As the centrifugal hammer of the oscillating member oscillates and moves in a direction away from the drum axis, the pushing arm of the oscillating member pushes the moving part against the applied force of the force-applying part in a direction that increases the insertion amount of the rotating body into the magnetic field space. Therefore, the magnetic brake device can control the braking force applied to the drum without being affected by the surface condition of the drum, and can reliably suppress recoil.

[0023] In item 2 above, the pushing arm of the swing member pushes the inclined surface of the moving member in a direction that approaches the drum shaft, thereby causing the moving member to slide in a direction that increases the insertion amount of the rotating body. Therefore, the pushing arm of the swing member can reliably make the moving member slide in a direction that increases the insertion amount of the rotating body.

[0024] In item 3 above, in the holding device of the magnetic brake device, with the side of the swing member disposed between a pair of holding plates formed on the moving member abutting against the inner surface of the holding plate portion, the swing member rotates integrally with the drum, thereby causing the moving member to rotate integrally with the drum. Therefore, the holding device can reliably hold the moving member so that it can rotate integrally with the drum.

[0025] In item 4 above, when the oscillating member rotates integrally with the drum, the convex spherical oscillating shaft protrusion formed on the side of the oscillating member abuts against the inner surface of the retaining plate in a point-contact state. Furthermore, when the moving member slides along the axial direction of the drum shaft, the retaining plate moves relative to the oscillating member in this point-contact state. Therefore, the frictional force generated by the contact between the side of the oscillating member and the inner surface of the retaining plate is small during the sliding movement of the moving member. This allows the moving member to slide smoothly.

[0026] Furthermore, the position where the swing shaft protrusion is formed is the end position of the swing shaft along the axial direction on the side of the swing member. Therefore, with the swing shaft protrusion of the swing member in point contact with the inner surface of the retaining plate, the swing member swings around the swing shaft protrusion on the inner surface of the retaining plate. Thus, even during the sliding movement of the moving part, the swing member can swing smoothly. Therefore, the magnetic braking device can smoothly increase or decrease the insertion amount of the rotating body in accordance with the rotational speed of the drum, that is, it can reliably control the braking force applied to the drum in accordance with the rotational speed of the drum.

[0027] In item 5 above, both the oscillating member and the retaining plate are made of resin, so the frictional force generated by the contact between the side of the oscillating member and the inner surface of the retaining plate is very small when the moving part slides. As a result, the moving part slides even more smoothly. Therefore, the magnetic braking device can smoothly increase or decrease the insertion amount of the rotating body in accordance with the rotational speed of the drum, that is, it can reliably control the braking force applied to the drum in accordance with the rotational speed of the drum.

[0028] In item 6 above, since the oscillating element and the holding device are arranged at multiple locations in the circumferential direction of the moving part, the magnetic braking device can reliably increase or decrease the insertion amount of the rotating body in accordance with the rotational speed of the drum, that is, it can reliably control the braking force applied to the drum in accordance with the rotational speed of the drum.

[0037] One embodiment of the present invention will be described below with reference to the accompanying drawings.

[0038] One embodiment of the present invention relates to a double-bearing type winding reel 1 (hereinafter also simply referred to as "winding reel 1"), such as... Figure 1 The diagram shows a component used when mounted on a fishing rod (not shown). In this embodiment, for ease of explanation, the width direction of the reel 1 is defined as the left-right direction (left L and right R) of the reel 1, and the direction in which the fishing line (not shown) is fed out of the reel 1 and its opposite direction are defined as the front F and rear B of the reel 1, respectively.

[0039] like Figure 1 As shown, the reel 1 includes: a cover 2 having a pair of left and right side frames 2a and 2b that are spaced apart from each other in a generally parallel manner in the left-right direction; a spool 10 for winding fishing line; a handle 3 for rotating the spool 10 to wind fishing line; and a magnetic brake device 20 for applying braking force to the spool 10 (see reference). Figure 2 and 3 ); towing mechanism 4; and horizontal winding mechanism 5, etc.

[0040] The handle 3 is located on the outside of one of the two side frames 2a and 2b of the cover 2. In this embodiment, for example, the handle 3 is located on the outside of the right side frame 2a (i.e., on the right side of the winding wheel 1).

[0041] The dragging mechanism 4 is a known structure that prevents the fishing line from breaking when a strong tensile force is applied to the fishing line, and includes a dragging knob 4a for adjusting the dragging force.

[0042] The flat winding mechanism 5 is a known configuration for evenly winding the fishing line onto the spool 10, and includes a fishing line guide hole (not shown) disposed on the front side of the spool 10 and guiding the fishing line to the spool 10.

[0043] like Figure 2 and 3 As shown, the reel 10 has a reel shaft 15 extending in the left-right direction (i.e., left side L and right side R) between the two side frames 2a and 2b of the cover 2 and rotatably mounted. The reel shaft 15 has a circular cross-section, and its two ends are rotatably supported by bearings 16, 16 respectively. Furthermore, in Figure 2 (and Figure 7 To make the construction of the magnetic braking device 20 easier to understand, the drum 10 is shown with an imaginary line (double-dotted line).

[0044] The spool 10 has: a fixed tube portion 11 into which the spool shaft 15 is inserted; a fishing line winding portion 12 disposed on the outer periphery of the fixed tube portion 11; and a generally circular annular connecting plate portion 13 that integrally connects the fixed tube portion 11 and the fishing line winding portion 12. Furthermore, the fishing line winding portion 12 is the part of the spool 10 where the fishing line is wound (the main body of the spool).

[0045] In the spool 10, the connecting plate portion 13 protrudes from one end of the fixed spool portion 11 (the left end if detailed) in a direction substantially perpendicular to the spool shaft 15 and is integrally formed with the fishing line winding portion 12. Moreover, the fixed spool portion 11 is fixed to the spool shaft 15 in a conventional manner, thereby the spool 10 is fixed to the spool shaft 15 in such a way that it rotates integrally with the spool shaft 15 around the spool shaft 15.

[0046] As one of the two side frame portions 2a and 2b of the cover 2, for example, on the inner side of the right frame portion 2a, a known power transmission mechanism (not shown) is provided for transmitting the rotational driving force of the handle 3 based on the rotational action of the handle 3 to the drum shaft 15, and a known clutch mechanism 6 (see reference 1). Figure 1 )wait.

[0047] The clutch mechanism 6 switches between an ON state, capable of transmitting the rotational driving force of the handle 3 to the drum shaft 15, and an OFF state, unable to transmit the rotational driving force of the handle 3 to the drum shaft 15, such as... Figure 1 The device shown includes a clutch lever 6a located on the rear side of the drum 10. The clutch mechanism 6 is configured such that by pressing down on the clutch lever 6a, the clutch mechanism 6 switches from an ON state to an OFF state.

[0048] Furthermore, the clutch mechanism 6 is equipped with a known automatic recovery mechanism (not shown) that automatically restores the clutch mechanism 6 from the OFF state to the ON state. Therefore, the clutch mechanism 6 is configured such that if, for example, the rotation operation of the handle 3 is started when the clutch mechanism 6 is in the OFF state, the clutch mechanism 6 is then automatically restored from the OFF state to the ON state by means of the automatic recovery mechanism.

[0049] The rotational driving force of the handle 3 is transmitted to the drum shaft 15 via the power transmission mechanism and the clutch mechanism 6. Therefore, when the clutch mechanism 6 is in the ON state, the rotational driving force of the handle 3 is transmitted to the drum shaft 15, and when the clutch mechanism 6 is in the OFF state, the rotational driving force of the handle 3 is not transmitted to the drum shaft 15.

[0050] The following describes the configuration of the magnetic braking device 20.

[0051] The magnetic braking device 20 is a device that applies braking force to the drum 10 when the drum 10 rotates due to the release of the fishing line.

[0052] like Figure 2 and 3 As shown, the magnetic braking device 20 includes: a magnetic field space 21 formed on one end of the spool shaft 15; a moving member 25 having a conductive rotating body 26 and being movable along the axial direction of the spool shaft 15; a holding device 30 that holds the moving member 25 rotatably together with the spool 10; and a control device 40 that controls the braking force applied to the spool 10 by increasing or decreasing the insertion amount S of the rotating body 26 into the magnetic field space 21.

[0053] In this embodiment, the magnetic field space 21 is formed on the left end side of the spool 15. For ease of explanation, the side of the magnetic field space 21 in the axial direction of the spool 15 and the moving member 25 is referred to as the top end side of the spool 15 and the moving member 25, and the opposite side is referred to as the base end side of the spool 15 and the moving member 25.

[0054] The magnetic field space 21 is formed by a generally cylindrical magnetic field gap between a generally cylindrical inner magnet 22 and a generally cylindrical outer magnet 23 disposed on its outer side. The inner magnet 22 and the outer magnet 23 are arranged in a concentric circle around the top end of the spool 15. A magnetic field is generated in the magnetic field space 21 by the inner magnet 22 and the outer magnet 23. That is, a magnetic field (magnetic boundary) is generated in the magnetic field space 21 that is substantially from the inner magnet 22 toward the outer magnet 23 or from the outer magnet 23 toward the inner magnet 22.

[0055] The outer magnet 23 is embedded and held within a generally cylindrical outer retainer 24. The user of the reel 1 rotates the outer retainer 24 circumferentially about the axis of the spool 15, thereby causing the outer magnet 23 and the outer retainer 24 to rotate circumferentially relative to the inner magnet 22, thus adjusting the magnetic field strength within the magnetic field space 21. The inner magnet 22 is held from its inside by an inner retainer (not shown).

[0056] like Figure 5 and 6 As shown, the moving member 25 is formed in a generally cylindrical shape. The spool 15 is inserted through the inner side 25a of the moving member 25, and in this state, the moving member 25 is disposed on the spool 15 in such a way that it can slide along the axial direction of the spool 15.

[0057] The rotating body 26 is a component made of conductive materials such as aluminum (including its alloys) and copper (including its alloys), and is formed in a cylindrical cup shape. Furthermore, as... Figure 3 As shown, the rotating body 26 is fixed to the rotating body fixing cylinder 25b, which is integrally formed on the top end of the moving member 25 (i.e., the end of the moving member 25 on the magnetic field space 21 side), using an adhesive or other fixing means, in a manner that allows it to move and rotate integrally with the moving member 25. At the top end of the moving member 25 (which, if detailed, is the rotating body fixing cylinder 25b), the rotating body 26 is arranged such that its peripheral wall tip 26a faces the magnetic field space 21 side. In this embodiment, as detailed... Figure 3 The top 26a of the peripheral wall of the rotating body 26 shown is inserted into the magnetic field space 21 through the entrance 21a and is located in the magnetic field space 21.

[0058] like Figure 3 As shown, in this embodiment, with the rotating body 26 inserted into the magnetic field space 21, the insertion amount S of the rotating body 26 into the magnetic field space 21 is defined as the length S from the position Q of the entrance 21a of the magnetic field space 21 to the top 26a of the peripheral wall of the rotating body 26.

[0059] The insertion amount S of the rotating body 26 into the magnetic field space 21 is increased by the sliding movement of the moving part 25 along the axis of the drum shaft 15 toward the magnetic field space 21 (same as L on the left in the figure) (see reference). Figure 8 The magnetic field strength is reduced by the sliding movement of the moving part 25 along the axis of the drum shaft 15 to the side opposite to the magnetic field space 21 (as shown on the right R in the figure).

[0060] The retaining device 30, as described above, enables the moving part 25 to be rotated integrally with the drum 10, and its detailed configuration will be described later.

[0061] like Figure 3As shown, the control device 40 of the magnetic braking device 20 includes: a coil spring (or a compression coil spring if described in detail) 49, which is a force-applying member that applies force to the moving member 25 in the direction of the reduced insertion amount S of the rotating body 26 into the magnetic field space 21; a swing member 41 having a centrifugal hammer portion 45 formed at one end and a push arm portion 47 formed at the other end; and a support member 50 that supports the swing member 41 in a swingable manner.

[0062] A coil spring 49 is inserted into the top end of the drum shaft 15, and in this state, the coil spring 49 is compressed between the receiving washer 56 fixed to the top end of the drum shaft 15 and the annular recess 29 formed at the top end of the moving member 25. Using the applied force generated by the elastic restoring force of the coil spring 49, the moving member 25 is always subjected to force in the direction of the reduced insertion amount S (R on the right in the same figure) into the magnetic field space 21 by the rotating body 26. Furthermore, reference numeral "57" indicates a stop ring (E-ring) for stopping the receiving washer 56.

[0063] The swing member 41 and the retaining device 30 (or, if detailed, the retaining plate portion 31, as described later) are disposed at multiple locations in the circumferential direction of the moving member 25. Specifically, there are two locations where the swing member 41 and the retaining device 30 are disposed, and the swing member 41 and the retaining device 30 are disposed on opposite sides of each other in the circumferential direction of the moving member 25. One set of swing members 41 and retaining devices 30 has the same configuration as another set of swing members 41 and retaining devices 30.

[0064] A circularly shaped swing shaft 46, extending along the width direction of the swing member 41, is provided between the centrifugal hammer portion 45 and the push arm portion 47 of the swing member 41. The swing member 41 is curved in a generally arc shape, such that the centrifugal hammer portion 45 and the push arm portion 47 are located approximately closer to the moving member 25 (reel shaft 15) than the swing shaft 46. The detailed configuration of the swing member 41 is as follows.

[0065] like Figure 6 As shown, a cavity 41a is formed between the centrifugal hammer portion 45 and the push arm portion 47 of the swing member 41. A pair of side plates 48, 48 are arranged on both sides of the cavity 41a in the width direction of the swing member 41 in a generally parallel manner. The centrifugal hammer portion 45 and the push arm portion 47 are integrally connected via the side plates 48, 48. The swing shaft 46 extends in the width direction of the swing member 41 in a manner that traverses the cavity 41a, and the side plates 48, 48 are integrally connected via the swing shaft 46.

[0066] In the swing member 41, the centrifugal hammer 45, the pressing arm 47, the swing shaft 46, and the two side plates 48 are integrally formed and are made of resin, as will be described later.

[0067] The support member 50 has: a generally circular annular base plate 51; and one or more support tabs 52 integrally formed protruding from the outer periphery of the base plate 51 toward the rotating body 26 (magnetic field space 21). The number of support tabs 52 is the same as the number of swing members 41, that is, two, and the two support tabs 52 are disposed on opposite sides of the outer periphery of the base plate 51 in the circumferential direction.

[0068] A bearing recess 53 with a roughly C-shaped cross-section is formed at the top end of the support tab 52. Furthermore, the top end of the support tab 52 is positioned between the two side plates 48, 48 of the swing member 41 (see reference). Figure 5 Furthermore, the centrifugal hammer portion 45 of the swing member 41 is located further to the top end of the moving member 25 (reel shaft 15) than the pressing arm portion 47. Moreover, in this state, the swing shaft 46 of the swing member 41 can oscillate and rotate within the bearing recess 53 of the support tab 52. Thus, the swing member 41 can oscillate around the swing shaft 46 and be supported within the bearing recess 53 of the support tab 52 of the support member 50.

[0069] On the inner side 51a of the substrate 51 of the support member 50 (refer to...) Figure 5 and 6 A reel shaft 15 is inserted through it. One or more (two in this embodiment) locking tabs 54 are integrally formed on the substrate 51, protruding in the opposite direction to the protrusion direction of the support tab 52.

[0070] like Figure 3 As shown, the substrate 51 overlaps with the connecting plate portion 13 of the drum 10 from the magnetic field space 21 side, and in this state, the locking piece 54 is inserted and locked into the locking hole 14 provided in the connecting plate portion 13. Thus, the support member 50 is fixed to the drum 10 in such a way that it rotates integrally with the drum 10 and that the position of the support member 50 relative to the drum 10 does not deviate from the axial direction of the drum shaft 15.

[0071] Therefore, if the drum 10 rotates, the oscillating member 41 rotates integrally with the drum 10 via the support member 50 in a state in which the position of the oscillating axis 46 of the oscillating member 41 relative to the drum 10 does not deviate from the axial direction of the drum shaft 15.

[0072] The support member 50, substrate 51, support tab 52 and locking tab 54 are integrally formed and are resin products such as POM resin (polyacetal resin).

[0073] The centrifugal hammer 45 of the swing member 41 swings about the swing shaft 46 in a direction away from the drum shaft 15, utilizing the centrifugal force acting on the centrifugal hammer 45 as the drum 10 rotates. The centrifugal force acting on the centrifugal hammer 45 increases or decreases accordingly with the rotational speed of the drum 10.

[0074] The centrifugal hammer 45 moves in a direction away from the drum shaft 15 using the centrifugal force, thereby causing the oscillating member 41 to push the moving member 25 against the force applied by the coil spring 49 in the direction of increasing the insertion amount S into the magnetic field space 21 of the rotating body 26 (L on the left in the same figure).

[0075] In order to reliably push and move the moving member 25 along the direction of increasing the insertion amount S of the rotating body 26 via the pushing arm portion 47, an inclined protrusion 28 is integrally formed at the base end of the moving member 25. The inclined protrusion 28 has an inclined surface 27 that is inclined toward the magnetic field space 21 side in the direction outside the radius of the moving member 25. In this embodiment, if described in detail, the inclined surface 27 is inclined toward the magnetic field space 21 side in a generally arc-shaped cross-section in the direction outside the radius of the moving member 25.

[0076] In the swing member 41, if the centrifugal hammer 45 of the swing member 41 moves away from the drum shaft 15 using the centrifugal force, the pushing arm 47 of the swing member 41 pushes the inclined surface 27 of the moving member 25 in the direction of approaching the drum shaft 15, thereby causing the moving member 25 to slide along the axial direction of the drum shaft 15 in the direction of increasing the insertion amount S of the rotating body 26 into the magnetic field space 21 against the applied force of the coil spring 49.

[0077] The insertion depth S of the rotating body 26 increases or decreases accordingly with the force exerted by the pushing arm 47 on the inclined surface 27 of the moving member 25. The force exerted by the pushing arm 47 on the inclined surface 27 of the moving member 25 increases or decreases accordingly with the centrifugal force acting on the centrifugal hammer 45. The centrifugal force, as described above, increases or decreases accordingly with the rotational speed of the drum 10. Therefore, the insertion depth S of the rotating body 26 increases or decreases accordingly with the rotational speed of the drum 10.

[0078] The retaining device 30, as described above, enables the moving part 25 to be rotated integrally with the drum 10. Specifically, as... Figure 5 and 6 As shown, a pair of retaining plates 31, 31 are provided at both ends of the swing shaft 46 of the swing member 41 in the axial direction and are arranged opposite each other. The two retaining plates 31, 31 are integrally formed on both sides of the inclined surface 27 of the moving member 25.

[0079] like Figure 6As shown, the swing member 41 (or, if detailed, the two side plates 48, 48, the swing shaft 46, and the push arm 47) is disposed between the two retaining plates 31, 31. In this state, the inclined surface 27 of the moving member 25 is shielded from both sides in its width direction by the two retaining plates 31, 31, and from its upper side by the support protrusion 52 (see reference). Figure 3 , 5 Therefore, it is difficult for tiny foreign objects (floating matter in the water, dried residue of water, suspended matter in the air, etc.) to adhere to the inclined surface 27. As a result, the pushing arm 47 of the swing member 41 can smoothly push the inclined surface 27 for a long time.

[0080] In the holding device 30, if the swing member 41 rotates integrally with the drum 10 via the support member 50, one of the two sides 42, 42 in the width direction of the swing member 41 abuts against the inner surface 31a of a holding plate portion 31. In this state, the holding plate portion 31 receives the rotational force from the swing member 41, thereby the moving member 25 rotates integrally with the drum 10.

[0081] As the rotational speed of the drum 10 increases, the rotational speed of the moving member 25 also increases. If the rotational speed of the drum 10 decreases, the other side 42 of the oscillating member 41 abuts against the inner surface 31a of the other retaining plate portion 31. Therefore, as the rotational speed of the drum 10 decreases, the rotational speed of the moving member 25 also decreases. Thus, the rotational speed of the moving member 25 increases or decreases accordingly with the rotational speed of the drum 10.

[0082] Here, regarding the configuration of the swing member 41, if we refer to... Figure 4 For details, see below. Furthermore, the axis of the swing axis 46 is indicated by reference numeral P in the same figure (shown as a single-dotted line).

[0083] At the two ends of the axis P of the swing shaft 46 on both sides 42, 42 in the width direction of the swing member 41, small convex spherical swing shaft protrusions 43 are integrally formed (see reference). Figure 6 The oscillating shaft protrusion 43 is a component in which the side surface 42 of the oscillating member 41 abuts against the inner surface 31a of the retaining plate portion 31 in a point contact state when the oscillating member 41 rotates integrally with the drum 10.

[0084] That is, if the oscillating member 41 rotates integrally with the drum 10 via the support member 50, the oscillating shaft protrusion 43 of one side 42 of the oscillating member 41 abuts against the inner surface 31a of a retaining plate 31 in a point contact state. In this state, the retaining plate 31 receives the rotational force from the oscillating member 41, thereby causing the moving member 25 to rotate integrally with the drum 10. Furthermore, if the rotational speed of the drum 10 decreases, the oscillating shaft protrusion 43 of the other side 42 of the oscillating member 41 abuts against the inner surface 31a of another retaining plate 31 in a point contact state. Thus, as the rotational speed of the drum 10 decreases, the rotational speed of the moving member 25 also decreases.

[0085] The retaining plate portion 31 is integrally formed with the moving member 25 as described above. Both the swing member 41 and the retaining plate portion 31 (moving member 25) are resin products (or, if detailed, rigid resin products). The type of resin used for the swing member 41 is not limited, but POM resin or the like is preferably used. The type of resin used for the retaining plate portion 31 is not limited, but PPS resin (polyphenylene sulfide resin) or the like is preferably used.

[0086] Therefore, in this embodiment, the winding wheel 1, as Figure 2 and 3 As shown above, the swing member 41 of the magnetic braking device 20 is supported by the support member 50 so that it can swing about the swing axis 46 of the swing member 41. The moving member 25 is held by the holding device 30 so that it can rotate integrally with the drum 10. The rotating body 26 of the moving member 25 is fixed to the top end of the moving member 25 (rotating body fixing cylinder 25b).

[0087] Before casting the fishing rig, the reel 10 is not rotating. At this time, as... Figure 3 As shown, the centrifugal hammer 45 of the oscillating member 41 is positioned at approximately the middle of the outer peripheral surface of the moving member 25 along its axial direction, i.e., the position closest to the drum shaft 15. The pushing arm 47 of the oscillating member 41 is positioned at the top end of the inclined surface 27 of the moving member 25. The base of the moving member 25 is pressed against the base plate 51 of the support member 50 by the force applied from the moving member 25 side using the coil spring 49. Furthermore, the insertion depth S of the rotating body 26 of the moving member 25 into the magnetic field space 21 is small (including 0). These positions are the initial positions of the centrifugal hammer 45 and the pushing arm 47 of the oscillating member 41, as well as the moving member 25 (rotating body 26).

[0088] In this embodiment, at the initial position, as described above, the top 26a of the peripheral wall of the rotating body 26 has been inserted into the magnetic field space 21 through the entrance 21a and is located within the magnetic field space 21, so the insertion amount S is slightly larger than 0. Thus, in this invention, it is particularly preferable that the insertion amount S at the initial position is slightly larger than 0, i.e., S > 0, but it is not limited to this, and the cases where S = 0 and S < 0 at the initial position (i.e., the rotating body 26 has not yet been inserted into the magnetic field space 21) are not excluded.

[0089] When starting to cast the fishing rig, by adjusting the clutch lever 6a of the clutch mechanism 6 (refer to...) Figure 1 The clutch mechanism 6 is switched from the ON to the OFF state by pressing down. As a result, the rotational drive force of the handle 3, based on its rotational action, is not transmitted to the reel shaft 15. The fishing rig is then cast after this state is reached.

[0090] Therefore, the fishing line wound on the spool 10 (or, in detail, the line winding portion 12 of the spool 10) is released from the spool 10. As the fishing line is released, the spool 10 rotates integrally with the spool shaft 15, centered on the spool shaft 15. With the rotation of the spool 10, centrifugal force acts on the centrifugal hammer portion 45 of the oscillating member 41, and the centrifugal hammer portion 45 uses this centrifugal force to oscillate and move about the oscillation axis 46 of the oscillating member 41 in a direction away from the spool shaft 15. Consequently, the pushing arm portion 47 of the oscillating member 41 pushes the inclined surface 27 of the moving member 25 in a direction approaching the spool shaft 15.

[0091] Thus, the moving part 25, which is pushed by the pushing arm 47 against the inclined surface 27, is as follows: Figure 7 and 8 The resisting coil spring 49 resists the force applied by the resisting coil spring 49 and slides along the axis of the drum shaft 15 in the direction of increasing the insertion amount S of the rotating body 26 into the magnetic field space 21.

[0092] If the insertion depth S of the rotating body 26 is increased, the electromagnetic force acting on the rotating body 26 in the direction opposite to its rotation direction increases. As a result, the braking force applied to the drum 10 increases, and the rotational speed of the drum 10 decreases.

[0093] If the rotational speed of the drum 10 is reduced, the centrifugal force acting on the centrifugal hammer 45 of the oscillating member 41 decreases. As a result, the force by which the pushing arm 47 of the oscillating member 41 pushes the inclined surface 27 of the moving member 25 in a direction close to the drum shaft 15 is reduced. Consequently, using the force applied by the coil spring 39, the moving member 25 slides along the axial direction of the drum shaft 15 in the direction of reducing the insertion amount S of the rotating body 26 into the magnetic field space 21.

[0094] Thus, the insertion amount S of the rotating body 26 is controlled in such a way that the rotational speed of the drum 10 increases or decreases accordingly, that is, the braking force applied to the drum 10 increases or decreases accordingly.

[0095] When the rotation of the drum 10 has stopped (i.e., when the rotational speed of the drum 10 has reached 0), the centrifugal hammer 45 and the push arm 47 of the swing member 41, as well as the moving member 25 (rotating body 26), return to Figure 2 and Figure 3 The initial position shown above.

[0096] According to the winding reel 1 of this embodiment, in the control device 40 of the magnetic braking device 20, the centrifugal hammer 45 of the swing member 41 swings about the swing shaft 46 in a direction away from the drum shaft 15 due to the centrifugal force acting on the centrifugal hammer 45 as the drum 10 rotates. By swinging the centrifugal hammer 45 of the swing member 41 in this way, the pushing arm 47 of the swing member 41 pushes the moving member 25 against the applied force of the coil spring 49 in a direction that increases the insertion amount S of the rotating body 26 into the magnetic field space 21. Therefore, the magnetic braking device 20 can control the braking force applied to the drum 10 without being affected by the surface condition of the drum 10, and can reliably suppress recoil.

[0097] Furthermore, the pushing arm 47 of the swing member 41 pushes the inclined surface 27 of the moving member 25 in a direction that approaches the drum shaft 15, thereby causing the moving member 25 to slide in a direction that increases the insertion amount S of the rotating body 26. Therefore, the pushing arm 47 of the swing member 41 can reliably make the moving member 25 slide in a direction that increases the insertion amount S of the rotating body 26.

[0098] Furthermore, in the holding device 30 of the magnetic braking device 20, with the side 42 of the swing member 41 disposed between the two holding plates 31, 31 integrally formed between the moving member 25 abutting against the inner surface 31a of the holding plate 31, the swing member 41 rotates integrally with the drum 10, thereby causing the moving member 25 to rotate integrally with the drum 10. Therefore, the holding device 30 can reliably hold the moving member 25 so that it can rotate integrally with the drum 10.

[0099] Furthermore, a convex spherical swing shaft protrusion 43 is formed on the side 42 of the swing member 41, so the magnetic braking device 20 of the winding wheel 1 in this embodiment has the following advantages compared with the conventional magnetic braking device described above.

[0100] That is, in the existing magnetic braking device described above, as shown, a guide groove extending along the axial direction of the drum shaft is formed in the moving part, and a small-diameter cylindrical metal pin protrudes outward in the radial direction of the drum shaft. Furthermore, the pin engages within the guide groove, allowing the moving part to rotate integrally with the drum. As the moving part moves along the axial direction of the drum shaft, the pin slides within the guide groove. Therefore, when the moving part rotates integrally with the drum, a force pushing from the pin in the rotational direction and a sliding friction force from the pin caused by its sliding movement within the guide groove are applied to the guide groove of the moving part. Consequently, the moving part cannot slide smoothly, easily hindering the adjustment of the insertion amount of the rotating body into the magnetic field space.

[0101] In contrast, in the magnetic braking device 20 of the winding reel 1 of this embodiment, when the oscillating member 41 rotates integrally with the drum 10, the convex spherical oscillating shaft protrusion 43 formed on the side surface 42 of the oscillating member 41 abuts against the inner surface 31a of the retaining plate portion 31 in a point contact state. Furthermore, when the moving member 25 slides along the axial direction of the drum shaft 15, the retaining plate portion 31 moves relative to the oscillating member 41 in this point contact state. Therefore, when the moving member 25 slides, the frictional force generated by the contact between the side surface 42 of the oscillating member 41 and the inner surface 31a of the retaining plate portion 31 is small. Thus, the moving member 25 slides smoothly.

[0102] Furthermore, since the position where the swing shaft protrusion 43 is formed on the swing member 41 is the end position of the axis P of the swing shaft 46 on the side surface 42 of the swing member 41, the swing member 41 swings about the swing shaft protrusion 43 on the inner surface 31a of the retaining plate 31 with point contact when the swing shaft protrusion 43 of the swing member 41 is in point contact with the inner surface 31a of the retaining plate 31. Therefore, even during the sliding movement of the moving member 25, the swing member 41 can swing smoothly. Therefore, the magnetic braking device 20 can smoothly increase or decrease the insertion amount S of the rotating body 26 in accordance with the rotational speed of the drum 10, that is, it can reliably control the braking force applied to the drum 10 in accordance with the rotational speed of the drum 10.

[0103] In addition, since the swing member 41 and the retaining plate 31 are both made of resin, the following advantages exist.

[0104] In the aforementioned existing magnetic braking device, the moving part is made of resin, but the pin that slides within the guide groove of the moving part is made of metal, specifically stainless steel. In this case, the sliding friction between the resin and the stainless steel generated during the sliding movement of the moving part is relatively large.

[0105] In contrast, in this embodiment, the swing member 41 and the retaining plate 31 are both made of resin, so the sliding friction between the resin components generated when the moving member 25 slides is generally smaller than the sliding friction between resin and stainless steel. Therefore, the moving member 25 slides more smoothly. Consequently, the magnetic brake device 20 can more smoothly increase or decrease the insertion amount S of the rotating body 26 in accordance with the rotational speed of the drum 10, that is, it can more reliably control the braking force applied to the drum 10 in accordance with the rotational speed of the drum 10.

[0106] Furthermore, since the swing member 41 and the retaining plate portion 31 are disposed on opposite sides of the moving member 25 in the circumferential direction, the magnetic braking device 20 can reliably increase or decrease the insertion amount S of the rotating body 26 in accordance with the rotational speed of the drum 10, that is, it can reliably control the braking force applied to the drum 10 in accordance with the rotational speed of the drum 10.

[0107] One embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0108] For example, in this invention, the swing member and the holding plate (holding device) may also be provided at three or more locations in the circumferential direction of the moving member.

[0109] Industrial availability This invention can be used in dual-bearing type reels for fishing.
