Description

TECHNICAL FIELD

[0001] The present application relates to a fishing reel provided with a fishing line guide body that guides the fishing line reeled in to a spool between side plates in front of the spool. BACKGROUND

[0002] In the past, a uniform winding device has been provided on a fishing reel of a double bearing type so as to uniformly wind a fishing line on a spool rotatably supported between left and right side plates. The uniform winding device is provided with a fishing line guide body that is linked to a reeling operation of a handle rotatably provided on one side plate side and moves to and fro in front of the spool, and that can uniformly wind the fishing line on the spool by passing the fishing line through the fishing line guide body.

[0003] As the fishing line guide body described above, there is known a configuration provided with an opening portion in which an opening area is formed wide so as to reduce resistance when the fishing line is paid out, and a narrow portion that guides the fishing line when the fishing line is reeled in and that is linked to a switching operation of a clutch to rotate the fishing line guide body (for example, Patent Literature 1). In this configuration, when the clutch is made OFF (disconnected), the opening portion is located in front of the spool, so that, at the time of casting operation, the fishing line wound on the spool is not subjected to large resistance from the inner face of the opening portion of the fishing line guide body, and thus it is possible to suppress reduction in the flight distance of the fishing tackle and to perform stable casting. Further, when the clutch is made ON (connected), the narrow guide portion is located in front of the spool, so that it is possible to uniformly reel in the fishing line on the spool.

[0004] The fishing line guide body described above is mounted on a holding body that is movable in the axial direction (left-right direction) and integrally rotatable with a tubular body that is rotatable in linkage with the operation of the clutch. On the holding body, a fitting pin that is fitted to a helical groove of a worm provided in the tubular body is provided, and the fishing line guide body is movable in the axial direction by the fitting relationship between the helical groove and the fitting pin by rotationally driving the worm.

[0005] Further, the tubular body and the holding body are configured to be integrally rotatable. In the configuration disclosed in Patent Literature 1, ribs extending in the axial direction are formed at substantially 180° intervals on the outer face of the tubular body, and they are integrally rotatable by fitting the ribs to recesses formed in the axial direction on the holding body. That is, it is configured that, when the tubular body is rotationally driven by the operation of the clutch, the holding body (fishing line guide body) is integrally rotatable with the tubular body by the fitting relationship described above.

[0006] Patent Literature

[0007] Patent Literature 1: Japanese Patent Application Laid-Open No. 2014-45 SUMMARY

[0008] On the above-described dual-bearing type line reel, the tubular body and the holding body (line guide body) are integrally rotated by the fitting relationship of the two ribs and the recess. The rotation of the holding body is formed in a state where the line is not reeled on the spool, that is, when the clutch mechanism is operated ON / OFF, and the line guide body is in a state of being stopped in the axial direction.

[0009] In the state where the clutch mechanism is ON, the holding body is axially slidable with respect to the tubular body by reeling operation of the handle.

[0010] The conventional holding body has a problem that, when being driven back and forth in the axial direction (left-right direction), it is easily loosened in the axial direction (loosening like the arrow D2, D3 of Figure 6 When the holding body is thus loosened, the line cannot be neatly reeled on the spool when the line is reeled, and resistance is generated when the line is next paid out. In addition, since the holding body is loosened, an abnormal sound is generated when the line is reeled, especially at high speed, and precision is lost.

[0011] The present application is made in view of the above-described problem, and the technical problem to be solved is to provide a fishing line reel in which a line guide body is configured to rotate, in which the line guide body is prevented from being loosened in the axial direction when the line is reeled.

[0012] To achieve the above-described object, the fishing line reel according to the present application has a spool rotatably supported between two side plates provided on both sides of a line reel body, a clutch mechanism that switches the spool between a line reeling state and a line paying-out state, and a uniform winding device that uniformly winds the line on the spool when the handle is rotated in the ON state of the clutch mechanism, characterized in that the uniform winding device has a tubular body rotatably supported between the two side plates and rotated in conjunction with the ON / OFF operation of the clutch mechanism, a worm housed inside the tubular body and rotationally driven by the rotation of the handle, a holding body provided with an engagement pin engaged with a helical groove of the worm and a line passage portion through which the line passes, and two circumferential stop portions provided on the holding body and the tubular body so that the holding body and the tubular body are integrally rotated, two circumferential stop portions are provided on the tubular body at intervals of 160° to 200°, and an axial stop portion that prevents the holding body from being loosened in the axial direction of the tubular body is provided at a position between the two circumferential stop portions.

[0013] According to the fishing reel constructed according to the present invention described above, the tubular body constituting the winding device and the retainer holding the fishing line through-hole can rotate integrally together with the clutch operation via two circumferential anti-rotation parts. The two circumferential anti-rotation parts are arranged on the tubular body at intervals of 160° to 200°, and an axial anti-rotation part is provided at the middle position to prevent the retainer from loosening axially in the tubular body. Therefore, when the fishing line is wound onto the spool, even if the retainer holding the fishing line through-hole is driven back and forth between the left and right side plates, axial loosening of the retainer can be prevented. Thus, since the retainer does not loosen axially, the fishing line can be accurately wound onto the spool, and the abnormal noise associated with loosening can be suppressed.

[0014] According to the present invention, a fishing reel in which the line guide rotates is provided, which can suppress axial loosening of the line guide during the reeling operation. Attached Figure Description

[0024] Below, refer to Figures 1 to 5 One embodiment of the fishing reel according to the present invention will be described.

[0025] Additionally, in the following explanation, the forward / backward (front, back), left / right, and up / down (above, below) directions are defined by... Figure 1 The direction is defined as shown.

[0026] like Figure 1 As shown, the fishing reel according to this embodiment has a reel body 1, which has two side plates (left side plate 1A and right side plate 1B) covering the left and right sides of the left and right frames 2a and 2b, respectively, with covers 3a and 3b. A reel foot is integrally formed on the reel body 1, located between the left side plate 1A and the right side plate 1B, and mounted on a fishing rod 100. Furthermore, a spool shaft is rotatably supported between the left and right frames 2a and 2b by bearings, and a spool 3 for winding fishing line is integrally fixed to the spool shaft.

[0027] In this embodiment, a handle 5 for rotating and driving the drum 3 is located on the left side plate 1A. A known power transmission mechanism is provided in the space between the left frame 2a and the left cover 3a to transmit the rotational driving force of the handle 5 to the drum shaft. Furthermore, a known clutch mechanism is provided on either side plate to switch the drum shaft between a power transmission state and a power cut-off state. This clutch mechanism can be switched from a clutch ON state (power transmission state) to a clutch OFF state (power cut-off state) by pressing the clutch lever 8 located between the left side plate 1A and the right side plate 1B on the rear side of the drum 3. Additionally, the return from the clutch OFF state to the clutch ON state can be achieved by rotating the handle 5 using a known automatic return mechanism.

[0028] Between the left side plate 1A and the right side plate 1B, a winding device 10 is provided on the front side of the drum 3.

[0029] The even winding device 10 includes: a fishing line guide 20 through which the fishing line wound on the spool 3 passes; a worm (screw) 11 that is driven to rotate by a driving force transmission mechanism; and a tubular body (cylinder) 12 for housing the worm 11 and configured to engage with the worm 11 by a locking pin provided on the fishing line guide 20 and be driven to move back and forth.

[0030] The worm gear 11 is housed within a tubular body 12, which is rotatably held between left and right side plates. An elongated hole 12a extending axially is formed on the outer surface of the tubular body 12. A helical groove 11a is formed on the surface of the worm gear 11, and this groove is exposed through the elongated hole 12a. Furthermore, the fishing line guide 20 includes: a retainer (body) 21 integrally formed of resin or the like; and a fishing line through-hole 22 integrally fixed to the upper part of the retainer 21, through which the fishing line actually passes. Through-holes 21a are formed along the left-right direction on the retainer 21, arranged in a fractional arrangement around the tubular body 12. That is, the tubular body 12 is in a state where it passes through the through-holes 21a of the retainer 21.

[0031] With the operation of the clutch lever 8 of the clutch mechanism, the tubular body 12 is rotated only by a predetermined angle. Specifically, when from... Figure 1 When the clutch is in the ON position as shown, pressing the clutch lever 8 to enter the OFF position will cause the clutch to move forward ( Figure 1 The drive tube 12 rotates (in the direction of arrow D1). Furthermore, when the clutch lever 8 is pressed, the power transmission mechanism for rotating the drive tube 12 can, for example, use a power transmission mechanism with the same configuration as disclosed in Patent Document 1. That is, when the clutch lever 8 is pressed, the drive clutch plate (not shown) rotates, and the drive tube 12 rotates via the engagement protrusion (not shown) of the clutch plate, which engages with the elongated hole 12B of the rotating plate 12A fixed to the tube 12 to prevent rotation.

[0032] The retainer 21 and the tubular body 12 are connected by a circumferential anti-rotation part to form a single rotatable unit. For example... Figure 3 As shown, in this embodiment, the circumferential anti-rotation portion is configured such that two radially protruding ribs 12b are formed on the tubular body 12, and two corresponding recesses 21b are formed on the retaining body 21, so that the ribs 12b fit together. These ribs 12b and recesses 21b are formed at intervals of 160° to 200° (intervals of about 180° ± 20°), thereby the retaining body 21 and the tubular body 12 are integrally rotated together.

[0033] Furthermore, through the interlocking relationship between the rib 12b and the recess 21b, during the fishing line reeling operation, the retainer 21 is guided to reciprocate in the left-right direction relative to the tubular body 12.

[0034] The retainer 21 has a cylindrical portion (in this embodiment, it is cylindrical) 21A that protrudes forward and forms the front end of the winding device 10. Inside the cylindrical portion, a locking pin 23 that engages with a spiral groove 11a formed on the surface of the worm 11 is received through an elongated hole 12a formed on the tubular body 12.

[0035] The engagement pin 23 has an engagement portion 23a that engages with the helical groove 11a and a body 23b that is pressed into the cylindrical portion 21A. The engagement pin 23 is configured to be prevented from coming off in a state of being pressed into the cylindrical portion 21A. As for this coming-off prevention structure, as shown in Figure 2 the drawing, it is configured by previously forming a through-hole 21d in the diameter direction of the cylindrical portion 21A, pressing the body 23b of the engagement pin 23 into the cylindrical portion 21A, and then pressing the coming-off prevention pin 25 in a state of engaging the engagement portion 23a with the helical groove 11a.

[0036] In addition, although in the present embodiment, the hollow portion 23c is formed in the body 23b in order to achieve lightening of the engagement pin 23, the body 23b can also be configured to be solid.

[0037] Further, on the cylindrical portion 21A, in order to prevent the coming-off prevention pin 25 from coming off in the radial direction, an O-ring 30 is installed in correspondence with the pressing position of the coming-off prevention pin 25. On the cylindrical portion 21A, a fixing groove 21B is formed in the circumferential direction, and by embedding the O-ring 30 into the fixing groove 21B, the coming-off prevention pin 25 can be prevented from coming off from the cylindrical portion 21A.

[0038] The fishing line passing portion 22 is fixed to the upper side of the holding body 21 by a fixing screw 28 or the like. As with the above-described Patent Document 1, the fishing line passing portion 22 has an opening portion 22A whose opening area is formed to be wide in order to reduce the resistance at the time of fishing line pay-out, and a narrow portion 22B that guides the fishing line at the time of fishing line winding, and is formed of a material such as SUS, titanium, or the like that has a small fishing line resistance.

[0039] When the clutch is made to be in the OFF state, the holding body 21 rotates together with the tubular body 12, and the opening portion 22A thereof is positioned in front of the reel 3 (fishing line pay-out state), and when the clutch is made to be in the ON state, the holding body 21 rotates in the opposite direction together with the tubular body 12, and the narrow portion 22B is positioned in front of the reel 3 (fishing line guide state).

[0040] According to the uniform winding device 10 configured as described above, since the opening portion 22A whose opening area is formed to be wide is positioned in front of the reel when the clutch is made to be in the OFF state at the time of casting operation, the fishing line that is payed out does not receive a large resistance from the inner face of the opening portion 22A, and thus it is possible to suppress the reduction of the flight distance of the fishing set and perform stable casting. Further, when the clutch is made to be in the ON state, the narrow portion 22B is positioned in front of the reel (refer to Figure 1). In this state, when the handle 5 is subjected to a winding operation, the line guide 20 (line passage 22) is reciprocally driven in the left-right direction by the engagement pin 23 engaged with the helical groove 11a of the screw shaft 11 which is rotationally driven, so that the line can be uniformly wound around the spool 3.

[0041] The rib 40 provided on the line guide 20 is integrally provided on the center of the holding body 21 in a manner protruding toward the front. By forming such a rib 40, it is possible to prevent the line from being entangled by entering the gap of the upper area of the cylindrical portion 21A or the step portion.

[0042] In addition, the rib 40 is formed in a shape (a shape that slides toward the direction of disengagement) that facilitates disengagement of the line causing a line failure or the like when the line comes into contact with the cylindrical portion 21A and its vicinity. That is, as shown in Figs. 6 and 7, by making the front end edge 40a of the rib 40 inclined so as to approach the central portion of the holding body 21 as it transitions from the cylindrical portion 21A side to the upper side (the line passage 22 side), it is possible to easily disengage the line upward. Figure 2 、 Figure 3

[0043] Further, in the present embodiment, an O-ring 30 is installed on the cylindrical portion 21A in correspondence with the press-in position of the disengagement preventing pin 25 so as to prevent the disengagement preventing pin 25 from being disengaged in the radial direction. The line can be entangled by entering the gap between the O-ring 30 and the lower surface 40b of the rib 40. Therefore, for the O-ring 30, it is preferable to be fitted so as to fill the gap between the lower surface 40b of the rib 40 of the cylindrical portion 21A and the opposite portion 21e opposite thereto by the relationship with the rib 40.

[0044] Further, in the present embodiment, as described above, on the cylindrical portion 21A, a fixing groove 21B for press-fitting and fixing the O-ring 30 is formed along the circumferential direction so as to prevent the O-ring 30 from easily disengaging from the cylindrical portion 21A.

[0045] For the fixing groove 21B, it is preferable to be formed in advance on a portion other than the area (opposite portion 21e) that becomes the opposite portion of the rib 40, rather than being formed on the entire circumference of the cylindrical portion 21A. In this way, by not forming the groove on a portion, it is possible to facilitate the fixing work of the O-ring 30, and since the fixing groove is not present on a portion where the line is likely to enter, the line is also not likely to be caught.

[0046] ​As described above, the circumferential stop portions (composed of two ribs 12b formed on the tubular body 12 and two recesses 21b formed on the holding body 21) are formed at intervals of 160° to 200° on the holding body 21 and the tubular body 12, whereby the two members are configured to be integrally rotatable. That is, by forming two circumferential stop portions at intervals of substantially 180° on the outer peripheral surface of the tubular body 12 and the inner peripheral surface of the holding body 21, when the tubular body 12 is rotated by operating the clutch mechanism, the tubular body 12 can be rotated integrally with the holding body 21 (the fishing line passage portion 22).

[0047] In the present application, in order to suppress loosening of the holding body 21 in the axial direction of the tubular body 12, an axial stop portion 50 is provided at the intermediate position of the two circumferential stop portions. The axial stop portion 50 is a device for preventing loosening in the axial direction when the holding body 21 reciprocates in the left-right direction by the worm 11 and the engagement pin 23 by the winding operation of the handle. That is, in the conventional configuration, as shown in FIG. 6, since only circumferential stop portions are provided at intervals of 180°, loosening in the axial direction (loosening in which the holding body 21 is rocked about the center) is caused. This loosening is mainly caused when the tension of the fishing line acts on the side surfaces 22B1, 22B2 of the narrow portion 22B of the fishing line passage portion 22 during the winding operation of the fishing line. Figure 6

[0048] Specifically, when the tension of the fishing line acts on the side surface 22B1 of the narrow portion 22B as the holding body 21 moves in the left-right direction, a force in the D2 direction acts on one end side of the holding body 21, which becomes a cause of loosening. Further, when the tension of the fishing line acts on the side surface 22B2 of the narrow portion 22B, a force in the D3 direction acts on the other end side of the holding body 21, which becomes a cause of loosening.

[0049] At this time, when a gap G is generated between the inner peripheral surface of the holding body 21 and the outer peripheral surface of the tubular body 12 due to dimensional tolerance, the loosening becomes large.

[0050] Therefore, in order to suppress the above-described loosening, by providing the axial stop portion 50 for preventing loosening of the holding body 21 in the axial direction at the intermediate position of the two circumferential stop portions, loosening of the holding body 21 in the axial direction of the tubular body 12 can be suppressed.

[0051] In the present embodiment, as shown in FIG. 7, the axial stop portion 50 is configured by a protrusion 12g formed on the outer peripheral surface of the tubular body 12 and a recess 21g formed on the inner peripheral surface of the holding body 21. Figures 4 to 6

[0052] ​​By providing such an axial anti-rotation part 50, during the fishing line reeling operation as described above, the loosening acting on the retainer 21 will cause the upper surface 12g′ of the protrusion 12g to abut against the bottom surface 21g′ of the groove 21g, thus restricting the movement of the retainer 21 in the D2 and D3 directions and suppressing the movement of the retainer 21 in the following ways. Figure 6 The loosening caused by movement in the D2 and D3 directions is shown. That is, since axial loosening is suppressed when the fishing line is wound onto the spool, even though the retainer 21 holding the fishing line through portion 22 is driven back and forth between the left and right side plates, the fishing line can be accurately wound onto the spool. Furthermore, since the abnormal noise associated with loosening is also suppressed, the precision of the fishing reel is improved. Moreover, by providing the axial anti-rotation portion 50, the rotation of the fishing line guide can be performed more stably.

[0053] The axial anti-rotation part 50 can be positioned at the midpoint of the two circumferential anti-rotation parts, but it is preferable to position it within a range R that is at least 45° away in the circumferential direction from each circumferential anti-rotation part (where the rib 12b is formed) (see reference). Figure 4 By providing the axial anti-rotation portion 50 within such a range R, loosening can be stably suppressed. In particular, it is preferable to provide the axial anti-rotation portion 50 within the range opposite to the engaging pin 23 engaged in the helical groove of the worm 11. That is, since a large force is generated axially at this engaging portion when the engaging pin 23 engages with the helical groove 11a of the worm 11 through the elongated hole 12a of the tubular body 12, thus preventing loosening... Figure 4 As shown, by placing the axial anti-rotation part 50 (protrusion 12g) on ​​the line Y between the center of the connecting locking pin and the axis C of the tubular body 12, loosening can be more effectively suppressed.

[0054] In fact, under the same conditions, for the configuration without the axial anti-rotation part 50 ( Figure 6 The configuration includes an axial anti-rotation part 50. Figure 5 When comparing the occurrence of loosening, the loosening is reduced by at least 10% and at most 35.9% when the configuration with the axial anti-rotation part 50 is provided.

[0055] Figure 7 This is a schematic diagram showing other components of the tubular body 12.

[0056] As shown in this embodiment, it is preferable that the protrusion 12g constituting the axial anti-rotation portion 50 is formed such that its height H is lower than the height of each rib 12b of the two circumferential anti-rotation portions, and its width W is wider.

[0057] Thus, by forming the protrusion 12g of the axial stopper 50 to be low in height and wide in width, the recess can be made shallow to prevent a decrease in strength, and the abutting area of the upper surface 12g' of the protrusion 12g and the bottom surface of the recess 21g can be widened, so that looseness can be more effectively suppressed.

[0058] While the embodiments of the present application have been described above, the present application is not limited to the above-described embodiments, and various modifications can be made.

[0059] The present application is characterized in the portion of the line guide 20 (holding body 21) and the tubular body 12 of the uniform winding device 10, and no particular limitation is imposed on the size, shape, other functional components, etc. of the reel body other than this. Furthermore, the configuration of the line passage 22, the holding structure of the engagement pin engaged with the screw shaft, etc. can also be appropriately modified.

[0060] Furthermore, as for the axial stopper 50, two or more can be provided as long as they are disposed at a position intermediate the two circumferential stoppers. Also, when the axial stopper 50 is formed using the fitting relationship of the protrusion 12g and the recess 21g, the height, width, depth of the groove, etc. can be appropriately modified.
