Description

[Technical Field]

[0001] The present invention relates to a fishing reel having a fishing line guide disposed between side plates in front of the spool for winding and guiding the fishing line onto the spool. [Background technology]

[0002] Conventionally, a double-bearing fishing reel is equipped with a level winding device to evenly wind the fishing line around a spool rotatably supported between left and right side plates. This level winding device has a fishing line guide that moves back and forth from side to side in front of the spool in conjunction with the winding operation of a handle rotatably mounted on one of the side plates. By inserting the fishing line through the fishing line guide, the fishing line can be evenly wound around the spool.

[0003] One known fishing line guide has a wide opening to reduce resistance when the line is released and a narrow section to guide the line when it is reeled in, and the line guide rotates in conjunction with the clutch switch (see, for example, Patent Document 1). With this type of configuration, when the clutch is switched off, the opening is positioned in front of the spool, so that the fishing line wound on the spool does not encounter significant resistance from the inner surface of the opening of the line guide, enabling stable casting while minimizing a reduction in the fishing tackle's casting distance. Furthermore, when the clutch is switched back on, the narrow guide section is positioned in front of the spool, allowing the fishing line to be evenly wound onto the spool.

[0004] The fishing line guide is attached to a holder that rotates axially (left and right) relative to the tubular body, which rotates in conjunction with clutch operation. The holder is provided with an engagement pin that engages with a spiral groove in a worm shaft disposed within the tubular body. When the worm shaft is rotated in conjunction with the rotation of the handle, the fishing line guide can move axially due to the engagement between the spiral groove and the engagement pin.

[0005] Furthermore, the tubular body and the holder are configured to rotate integrally. In the configuration disclosed in Patent Document 1, axially extending ribs are formed on the outer surface of the tubular body at approximately 180-degree intervals, and these ribs are fitted into recesses formed in the holder along the axial direction, allowing the tubular body and the holder to rotate integrally. In other words, when the tubular body is driven to rotate by clutch operation, the holder (fishing line guide) is configured to rotate integrally with the tubular body due to the above-mentioned fitting relationship. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent Publication No. 2014-45 Summary of the Invention [Problem to be solved by the invention]

[0007] In the double-bearing reel described above, the tubular body and the holder (fishing line guide) can rotate together due to the fitting relationship between the two ribs and recesses. The holder rotates when no fishing line is wound onto the spool, i.e., when the clutch mechanism is turned on and off, and the fishing line guide is stopped in the axial direction. With the clutch mechanism turned on, the holder slides in the axial direction relative to the tubular body by winding the handle.

[0008] Conventional holders have a problem in that they are prone to axial rattle when reciprocated in the axial direction (left and right direction) (the shaking rattle indicated by arrows D2 and D3 in Figure 6). When the holder rattles in this way, the fishing line cannot be neatly wound around the spool during the reeling operation, resulting in resistance when the line is released again. Furthermore, the rattle of the holder causes abnormal noise during the reeling operation, especially at high speeds, resulting in a lack of precision.

[0009] The present invention has been made in response to the above-mentioned problems, and aims to provide a fishing reel having a structure in which a fishing line guide rotates, in which the fishing line guide is prevented from rattling in the axial direction when the fishing line is wound up. [Means for solving the problem]

[0010] In order to achieve the above object, the fishing reel of the present invention has a spool rotatably supported between left and right side plates of a reel body, a clutch mechanism that switches the spool between a fishing line winding state and a fishing line releasing state, and a level winding device that evenly winds the fishing line onto the spool when the handle is rotated while the clutch mechanism is in the ON state, and the level winding device comprises a tubular body that is rotatably supported between the left and right side plates of the reel body and rotates in conjunction with the ON / OFF operation of the clutch mechanism, and a level winding device that is housed within the tubular body and that is connected to the handle. the tubular body and the worm shaft are provided with an engaging pin that engages with the spiral groove of the worm shaft and holds the fishing line insertion portion through which the fishing line is inserted; and two circumferential anti-rotation portions provided on the tubular body and the holder so that the holder and the tubular body rotate together, the two circumferential anti-rotation portions being provided on the tubular body at approximately 180° intervals, and an axial anti-rotation portion being provided at an intermediate position between the two circumferential anti-rotation portions to prevent the holder from rattling in the axial direction of the tubular body.

[0011] In the fishing reel configured as described above, the tubular body constituting the level winding device and the holder that holds the fishing line insertion portion are rotated together by two circumferential anti-rotation portions when the clutch is operated. The two circumferential anti-rotation portions are provided on the tubular body at approximately 180° intervals, and an axial anti-rotation portion is provided at the middle position to prevent the holder from rattling in the axial direction of the tubular body. Therefore, even when the holder that holds the fishing line insertion portion is driven back and forth between the left and right side plates when winding the fishing line onto the spool, rattling of the holder along the axial direction is prevented. Because the holder does not rattle along the axial direction, the fishing line is accurately wound onto the spool and noise caused by rattling is suppressed. [Effects of the Invention]

[0012] According to the present invention, a fishing reel having a structure in which a fishing line guide member rotates can be obtained in which the fishing line guide member is prevented from rattling in the axial direction during a fishing line winding operation.

[0014] Hereinafter, an embodiment of a fishing reel according to the present invention will be described with reference to FIGS. In the following description, the front-rear direction (front, rear), left-right direction, and up-down direction (up, down) are defined as the directions shown in FIG.

[0015] As shown in Figure 1, the fishing reel according to this embodiment has a reel body 1 equipped with left and right side plates 1A, 1B, which are made up of left and right frames 2a, 2b covered by left and right covers 3a, 3b, respectively. Reel legs that are located between the left and right side plates and are attached to a fishing rod 100 are integrally formed with the reel body 1. A spool shaft is rotatably supported between the left and right frames 2a, 2b via bearings, and a spool 3 around which fishing line is wound is integrally fixed to the spool shaft.

[0016] In this embodiment, the handle 5 that rotates the spool 3 is installed on the left side plate 1A side, and a known power transmission mechanism that transmits the rotational driving force of the handle 5 to the spool shaft is disposed in the space between the left frame 2a and the left cover 3a. A known clutch mechanism that switches the spool shaft between a power-on state and a power-off state is also disposed on one of the side plates. This clutch mechanism switches from a clutch-on state (power-on state) to an OFF state (power-off state) by pressing down a clutch lever 8 disposed between the left and right side plates behind the spool 3. Returning from the clutch-off state to the clutch-on state can be achieved by rotating the handle 5 using a known automatic return mechanism.

[0017] A level wind device 10 is disposed in front of the spool 3 between the left and right side plates 1A and 1B. The level wind device 10 comprises a fishing line guide 20 through which the fishing line wound on the spool 3 is passed, a worm shaft (screw shaft) 11 that is driven to rotate via the drive force transmission mechanism, and a tubular body (cylinder) 12 that houses the worm shaft 11, and is configured to be driven back and forth left and right by an engagement pin provided on the fishing line guide 20 engaging with the worm shaft 11.

[0018] The worm shaft 11 is housed within a tubular body 12 that is rotatably held between left and right side plates, and an elongated hole 12a extending axially is formed in the outer surface of the tubular body 12. A spiral groove 11a is formed in the surface of the worm shaft 11, and this spiral groove 11a is exposed through the elongated hole 12a. The fishing line guide 20 includes a holder (main body) 21 integrally formed from resin or the like, and a fishing line insertion portion 22 that is fixed integrally to the upper part of the holder 21 and through which the fishing line is actually inserted. A through hole 21a is formed in the holder 21 along the left-right direction, and is positioned and formed to surround the tubular body 12. In other words, the tubular body 12 is inserted through the through hole 21a of the holder 21.

[0019] The tubular body 12 is driven to rotate by a predetermined angle in response to operation of the clutch lever 8 of the clutch mechanism. Specifically, when the clutch lever 8 is pressed down from the clutch-on state shown in FIG. 1 to the clutch-off state, the tubular body 12 is driven to rotate toward the user (in the direction of arrow D1 in FIG. 1). Note that a power transmission mechanism for rotating the tubular body 12 when the clutch lever 8 is pressed down can be, for example, a power transmission mechanism similar to the configuration disclosed in the above-mentioned Patent Document 1. That is, when the clutch lever 8 is pressed down, a clutch plate (not shown) is driven to rotate, and the tubular body 12 is driven to rotate via an engaging protrusion (not shown) of the clutch plate that engages with an elongated hole 12B of a rotating plate 12A fixed to the tubular body 12 in a rotation-preventing manner.

[0020] The holder 21 and the tubular body 12 are connected by a circumferential anti-rotation portion so as to be integrally rotatable. As shown in Fig. 3, the circumferential anti-rotation portion in this embodiment is configured by forming two ribs 12b protruding in the radial direction on the tubular body 12 and forming two corresponding recesses 21b on the holder 21 so that the ribs 12b fit into them. These ribs 12b and recesses 21b are formed at intervals of approximately 180° (including approximately 180°±20°), so that the holder 21 can be rotated integrally with the tubular body 12. The fitting relationship between the rib 12b and the recess 21b guides the holder 21 in its reciprocating motion in the left and right directions relative to the tubular body 12 during the fishing line winding operation.

[0021] The retaining body 21 has a tubular portion (cylindrical in this embodiment) 21A that protrudes forward and forms the front end of the level wind device 10, and inside it is accommodated an engagement pin 23 that engages with a spiral groove 11a formed on the surface of the worm shaft 11 through a long hole 12a formed in the tubular body 12.

[0022] The engagement pin 23 includes an engagement portion 23a that engages with the spiral groove 11a and a main body 23b that is press-fitted into the cylindrical portion 21A. The engagement pin 23 is configured to be retained while pressed into the cylindrical portion 21A. As shown in Fig. 2, this retaining structure is configured by forming a through-hole 21d in the diameter direction of the cylindrical portion 21A, press-fitting the main body 23b of the engagement pin 23 into the cylindrical portion 21A, and press-fitting the retaining pin 25 while the engagement portion 23a is engaged with the spiral groove 11a. In this embodiment, the hollow portion 23c is formed in the main body 23b to reduce the weight of the engagement pin 23, but the main body 23b may be configured to be solid.

[0023] An O-ring 30 is attached to the cylindrical portion 21A in correspondence with the press-fit position of the retaining pin 25 to prevent the retaining pin 25 from coming out in the radial direction. A fixing groove 21B is formed in the cylindrical portion 21A along the circumferential direction, and by fitting the O-ring 30 into the fixing groove 21B, the retaining pin 25 is prevented from coming out of the cylindrical portion 21A.

[0024] The fishing line insertion portion 22 is fixed to the upper surface of the holder 21 with a set screw 28 or the like. Similar to Patent Document 1, the fishing line insertion portion 22 has an opening 22A with a wide opening area to reduce resistance when the fishing line is released, and a narrow portion 22B that guides the fishing line when it is wound up, and is made of a material with low fishing line resistance, such as SUS or titanium. When the clutch is turned OFF, the holder 21 rotates together with the tubular body 12, and the opening 22A is positioned in front of the spool 3 (fishing line release state), and when the clutch is turned ON, the holder 21 rotates in the opposite direction together with the tubular body 12, and the narrow portion 22B is positioned in front of the spool 3 (fishing line guide state).

[0025] With the level wind device 10 configured as described above, when the clutch mechanism is turned OFF during casting, the opening 22A, which has a wide opening area, is located in front of the spool. This prevents the released fishing line from encountering significant resistance from the inner surface of the opening 22A, enabling stable casting while suppressing a decrease in the fishing tackle's casting distance. When the clutch mechanism is returned to ON, the narrow portion 22B is located in front of the spool (see FIG. 1). When the handle 5 is operated for reeling in this state, the fishing line guide 20 (fishing line insertion portion 22) is driven back and forth in the left-right direction by the engagement pin 23, which engages with the spiral groove 11a of the rotatably driven worm shaft 11, causing the fishing line to be evenly wound around the spool 3.

[0026] The rib 40 provided on the fishing line guide body 20 is integrally provided at the center of the holder body 21 so as to protrude forward. By forming such a rib 40, the fishing line is prevented from getting caught in gaps or steps in the upper region of the cylindrical portion 21A and becoming tangled.

[0027] The rib 40 is formed in a shape that allows the fishing line, which has caused line trouble or the like, to easily slip out (a shape that allows the line to slide in the direction of slipping out) when it comes into contact with the cylindrical portion 21A or its vicinity. That is, as shown in Figures 2 and 3, the front end edge 40a is made inclined so that it approaches the center of the holder 21 as it moves from the cylindrical portion 21A side to the upper side (the fishing line insertion portion 22 side), making it easier for the fishing line to slip out upward.

[0028] In this embodiment, an O-ring 30 is attached to the cylindrical portion 21A corresponding to the press-fit position of the retaining pin 25 to prevent the retaining pin 25 from coming out in the radial direction. The fishing line may get caught in the gap between the O-ring 30 and the lower surface 40b of the rib 40, causing the line to become tangled. For this reason, it is preferable to arrange the O-ring 30 in relation to the rib 40 so that it fills the gap between the lower surface 40b of the rib 40 of the cylindrical portion 21A and the opposing portion 21e.

[0029] Furthermore, in this embodiment, as described above, a fixing groove 21B for press-fitting and fixing the O-ring 30 is formed along the circumferential direction in the cylindrical portion 21A, making it difficult for the O-ring 30 to come off the cylindrical portion 21A. It is preferable that fixing groove 21B is not formed around the entire circumference of cylindrical portion 21A, but is formed excluding the area (facing portion 21e) that faces rib 40. By not forming a groove in a portion like this, the work of fixing O-ring 30 can be easily performed, and since there is no fixing groove in the area where the fishing line is likely to enter, the fishing line will not get caught.

[0030] As described above, the holder 21 and the tubular body 12 are formed with circumferential anti-rotation portions (consisting of two ribs 12b formed on the tubular body 12 and two recesses 21b formed on the holder 21) spaced approximately 180° apart, allowing the two components to rotate integrally. That is, by forming two circumferential anti-rotation portions approximately 180° apart on the outer circumferential surface of the tubular body 12 and the inner circumferential surface of the holder 21, when the clutch mechanism is operated to rotate the tubular body 12, it becomes possible to rotate the holder 21 (fishing line insertion portion 22) integrally with the tubular body 12.

[0031] In the present invention, an axial anti-rotation portion 50 is provided intermediate the two circumferential anti-rotation portions to prevent the holder 21 from rattling in the axial direction of the tubular body 12. This axial anti-rotation portion 50 prevents rattling along the axial direction when the holder 21 moves back and forth left and right via the worm shaft 11 and the engagement pin 23 during the reeling operation of the handle. That is, in the conventional configuration, as shown in FIG. 6, only circumferential anti-rotation portions are provided at approximately 180° intervals, which causes rattling along the axial direction (i.e., rattling around the holder 21). This rattling occurs mainly when the tension of the fishing line acts on the side surfaces 22B1 and 22B2 of the narrow portion 22B of the fishing line insertion portion 22 during the reeling operation of the fishing line.

[0032] Specifically, when tension in the fishing line acts on side surface 22B1 of narrow portion 22B as holder 21 moves left and right, a force in the direction D2 acts on one end of holder 21, causing rattle. Also, when tension in the fishing line acts on side surface 22B2 of narrow portion 22B, a force in the direction D3 acts on the other end of holder 21, causing rattle. In this case, if a gap G occurs between the inner peripheral surface of the holder 21 and the outer peripheral surface of the tubular body 12 due to dimensional tolerances, the rattle will become large.

[0033] Therefore, in order to suppress the above-mentioned rattle, an axial anti-rotation portion 50 that prevents the retaining body 21 from rattling along the axial direction is provided at the intermediate position between the two circumferential anti-rotation portions, thereby suppressing the rattle of the retaining body 21 in the axial direction of the tubular body 12. In this embodiment, the axial anti-rotation portion 50 is composed of a convex portion 12g formed on the outer peripheral surface of the tubular body 12 and a concave groove 21g formed on the inner peripheral surface of the retaining body 21, as shown in Figures 4 to 6.

[0034] By providing this axial anti-rotation portion 50, the rattle acting on the holder 21 during the fishing line winding operation described above is limited by the abutment between the upper surface 12g' of the convex portion 12g and the bottom surface 21g' of the concave groove 21g, restricting movement of the holder 21 in the D2 and D3 directions. This makes it possible to suppress rattle due to movement in the D2 and D3 directions as shown in FIG. 6. In other words, even when the holder 21 holding the fishing line insertion portion 22 is driven back and forth between the left and right side plates when winding the fishing line onto the spool, rattle along the axial direction is suppressed. This allows the fishing line to be wound onto the spool accurately, and the generation of abnormal noise associated with rattle is suppressed, improving the precision of the fishing reel. Furthermore, the provision of the axial anti-rotation portion 50 allows the fishing line guide to rotate more stably.

[0035] The axial anti-rotation portion 50 may be provided at any position intermediate the two circumferential anti-rotation portions. However, it is preferable to provide the axial anti-rotation portion 50 within a range R that is 45° or more circumferentially away from each of the circumferential anti-rotation portions (the positions where the ribs 12b are formed) (see FIG. 4). Providing the axial anti-rotation portion 50 within such range R makes it possible to stably suppress rattle. In particular, it is preferable to provide the axial anti-rotation portion 50 within a range facing the engagement pin 23 that engages with the helical groove of the worm shaft 11. That is, when the engagement pin 23 engages with the helical groove 11a of the worm shaft 11 through the elongated hole 12a of the tubular body 12, a large force is generated in the axial direction at this engagement portion. Therefore, by providing the axial anti-rotation portion 50 (protrusion 12g) on ​​a line Y connecting the center of the engagement pin and the axial center C of the tubular body 12, as shown in FIG. 4, rattle can be more effectively suppressed.

[0036] In fact, a comparative test was conducted under the same conditions to check for the occurrence of rattle between a configuration without an axial anti-rotation portion 50 (FIG. 6) and a configuration with an axial anti-rotation portion 50 (FIG. 5). It was confirmed that the configuration with the axial anti-rotation portion 50 reduced rattle by at least 10% and at most 35.9%.

[0037] FIG. 7 is a schematic diagram showing another configuration of the tubular body 12. In FIG. As shown in this embodiment, it is preferable that the protrusion 12g constituting the axial anti-rotation portion 50 has a height H smaller than each of the ribs 12b of the two circumferential anti-rotation portions and a width W larger than each of the ribs 12b.

[0038] In this way, by forming the convex portion 12g of the axial anti-rotation portion 50 to be low in height and wide in width, the groove can be made shallower to prevent a decrease in strength, and the contact area between the upper surface 12g' of the convex portion 12g and the bottom surface of the groove 21g is increased, making it possible to more effectively suppress rattle.

[0039] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and can be modified in various ways.

[0040] The present invention is characterized by the fishing line guide body 20 (retainer 21) and tubular body 12 of the level wind device 10, and other configurations, such as the size and shape of the reel body and other functional components, are not particularly limited. In addition, the configuration of the fishing line insertion portion 22, the retaining structure of the engagement pin that engages with the screw shaft, etc. can also be modified as appropriate.

[0041] Furthermore, two or more axial anti-rotation portions 50 may be provided as long as they are located intermediate between two circumferential anti-rotation portions. Furthermore, when axial anti-rotation portion 50 is formed by the fitting relationship between protrusion 12g and recessed groove 21g, the height, width, groove depth, etc. can be modified as appropriate.
