Description

  The present invention relates to a fishing spinning reel provided with an oscillating mechanism that converts a rotational movement of a handle shaft into a reciprocating linear motion and transmits it to a spool shaft.

  The fishing spinning reel includes a reel body positioned behind the spool and the rotor. The reel body incorporates an oscillating mechanism for winding the fishing line evenly around the spool.

  The oscillating mechanism is for converting the rotational motion of the handle shaft into a reciprocating linear motion and transmitting it to the spool shaft, and examples thereof are disclosed in Patent Document 1 and Patent Document 2, for example.

  The oscillating mechanisms disclosed in Patent Document 1 and Patent Document 2 include a drive gear that rotates following the handle shaft and a slider that reciprocates together with the spool shaft. The drive gear has a convex portion at a position eccentric from its rotation center. The convex portion revolves by rotation of the drive gear and is slidably fitted in a guide groove formed in the slider. The guide groove extends along the height direction of the reel body so as to be orthogonal to the spool shaft.

  In this type of oscillating mechanism, when the driving gear rotates in accordance with the winding operation of the handle, the revolving convex portion moves in the guide groove along the longitudinal direction. As a result, the rotational motion of the drive gear is converted into a reciprocating linear motion by the fitting between the revolving convex portion and the guide groove and transmitted to the slider. Since the slider is fixed to the rear end of the spool shaft, the spool shaft reciprocates linearly in the axial direction following the movement of the slider.

  Furthermore, in the oscillating mechanism disclosed in Patent Document 1 and Patent Document 2, a device for enabling a smooth operation of the slider is devised. Specifically, in the case of Patent Document 1, a guide rod that is parallel to the spool shaft is installed inside the reel body, and this guide rod penetrates the slider in a slidable manner.

  With this configuration, the slider can be supported by two parallel shafts, and rattling of the slider in the direction intersecting with the moving direction of the slider and the rotating direction of the drive gear can be eliminated.

  On the other hand, according to Patent Document 2, a support portion protruding upward is formed at the upper end portion of the slider, and a ball bearing is attached to the upper end of the support portion. The ball bearing is rotatably in contact with a pair of guide portions formed inside the reel body. The guide portions extend in the axial direction of the spool shaft and are arranged parallel to each other with a space therebetween, and the ball bearing is interposed between the guide portions.

According to this configuration, the upper end portion of the slider can be directly supported by the reel body, and rattling of the slider in the direction crossing the moving direction of the slider and the rotating direction of the drive gear can be eliminated.
Registered Utility Model No. 3012426 JP 2002-345372 A

  According to the oscillating mechanism disclosed in Patent Document 1, the guide rod penetrating the slider is largely biased to the opposite side of the guide groove below the spool shaft. For this reason, the slider has a boss portion that projects to the opposite side of the guide groove, and the spool shaft and the guide rod pass through the boss portion.

  However, according to this configuration, since the thickness dimension of the slider increases due to the presence of the boss portion, it is necessary to secure a wide space for arranging the slider and the drive gear around the handle shaft. For this reason, the reel main body must be enlarged, and the fishing spinning reel becomes heavy and large.

  According to the oscillating mechanism disclosed in Patent Document 2, since the bearing protrudes above the slider, it is necessary to secure a space for installing the bearing and the guide portion in which the bearing is rotatably contacted above the slider. In particular, since the guide portion needs to have a length corresponding to the moving distance of the slider, more and more space is required above the slider.

  As a result, the reel body must be expanded in the axial direction of the spool shaft and in the vertical direction perpendicular to the spool shaft, and it is inevitable that the fishing spinning reel becomes heavy and large.

  It is an object of the present invention to obtain a fishing spinning reel that can be smoothly moved while a reel body can be formed compactly and can be reduced in size and weight.

In order to achieve the above object, a fishing spinning reel according to one aspect of the present invention is provided.

The guide groove of the slider extends in the height direction of the reel body behind the spool shaft, and the guide groove is on the extension of the spool shaft when the spool shaft is viewed from the axial direction. The spool shaft is positioned and at least a part of the spool shaft along the radial direction overlaps the guide groove .

According to the present invention, the amount of eccentricity of the slider along the radial direction of the spool shaft can be reduced , and the reel body can be reduced in size and weight even though the slider is supported by both the spool shaft and the guide shaft. Become.

First, a basic configuration of a fishing spinning reel having relevance to the present invention will be described based on a first reference example shown in FIGS.

  FIG. 1 discloses a fishing spinning reel 1. The fishing spinning reel 1 includes a reel body 2. The reel body 2 is made of a lightweight metal material such as a magnesium alloy or an aluminum alloy. The reel body 2 has a leg portion 3 extending upward, and an upper end portion of the leg portion 3 is fixed to a reel seat of a fishing rod (not shown).

  As shown in FIG. 3, the reel body 2 includes a case 4 integrated with the leg 3 and a side cover 5 screwed to the left side surface of the case 4. The case 4 and the side cover 5 cooperate with each other to form a storage chamber 6 inside the reel body 2.

  A rotor sleeve 9 is rotatably supported at the front end portion of the case 4 via a bearing 8. The rotor sleeve 9 extends in the front-rear direction of the reel body 2, and the front half portion protrudes from the front end portion of the case 4. A rotor 10 is coaxially fixed to the front end portion of the rotor sleeve 9.

  The rotor sleeve 9 has a pinion gear 11. The pinion gear 11 is located at the rear end portion of the rotor sleeve 9 and is exposed at the front end portion of the storage chamber 6.

  A spool shaft 12 is coaxially inserted inside the rotor sleeve 9. The spool shaft 12 is supported by the case 4 so as to be able to reciprocate linearly in the axial direction. A front portion of the spool shaft 12 projects forward of the rotor 10. The rear portion of the spool shaft 12 passes through the pinion gear 11 of the rotor sleeve 9 and is guided to the storage chamber 6.

  A spool 14 is fixed to the front portion of the spool shaft 12. The spool 14 can reciprocate in the axial direction together with the spool shaft 12. The spool 14 has a small diameter portion 15 around which the fishing line is wound, and a large diameter portion 16 located behind the small diameter portion 15. The large diameter portion 16 of the spool 14 is coaxially covered on the outer periphery of the rotor 10.

  The rotor 10 has a pair of arms 17 (only one is shown). The arm 17 protrudes from the rotor 10 toward the front of the reel body 2, and a fishing line guide device 18 is attached between the distal ends of the arm 17. The fishing line guide device 18 is for guiding the fishing line to the small diameter portion 15 of the spool 14, and includes a bail 19 straddling between the arms 17.

  As shown in FIG. 3, the reel body 2 rotatably supports the boss portion 22 of the rotor drive gear 21. The boss portion 22 straddles between the right side wall 4 a of the case 4 and the side cover 5 and crosses the storage chamber 6 in the width direction of the reel body 2. The boss portion 22 is located behind the pinion gear 11, and the rotor drive gear 21 integrated with the boss portion 22 is engaged with the pinion gear 11.

  Further, a relay gear 23 is provided on the outer periphery of the boss portion 22. The relay gear 23 rotates following the boss portion 22 and is housed in the housing chamber 6 together with the boss portion 22 and the rotor drive gear 21.

  As shown in FIGS. 1 and 2, a handle shaft 25 is inserted inside the boss portion 22 of the rotor drive gear 21. The handle shaft 25 rotates integrally with the boss portion 22 by meshing with the inner surface of the boss portion 22. The handle shaft 25 extends in the width direction of the reel body 2 so as to be orthogonal to the spool shaft 12. One end of the handle shaft 25 protrudes to the side of the reel body 2, and a handle 26 is attached to the protruding end of the handle shaft 25.

  When the angler turns the handle 26 by hand, the rotor drive gear 21 rotates via the handle shaft 25 and the boss portion 22. Since the rotor drive gear 21 meshes with the pinion gear 11 of the rotor sleeve 9, the rotor sleeve 9 is rotated via the pinion gear 11. As a result, the rotor 10 fixed to the rotor sleeve 9 rotates in the direction of winding the fishing line.

  As shown in FIGS. 1 to 3, an oscillating mechanism 30 is accommodated in the accommodation chamber 6 of the reel body 2. The oscillating mechanism 30 is for converting the rotational motion of the handle shaft 25 into a reciprocating linear motion and transmitting it to the spool shaft 12.

  The oscillating mechanism 30 includes an oscillating drive gear 31, a slider 32, and a guide shaft 33. The oscillating drive gear 31 is rotatably supported on the inner surface of the right side wall 4 a of the case 4 via a screw 34. The oscillating drive gear 31 is located behind the handle shaft 25 and is interposed between the rear portion of the spool shaft 12 and the right side wall 4 a of the case 4. The oscillation drive gear 31 meshes with the relay gear 23.

  Further, the oscillating drive gear 31 has a cylindrical convex portion 35 on the end surface on the spool shaft 12 side. The convex portion 35 is provided at a position eccentric from the rotation center of the oscillating drive gear 31. For this reason, the protrusion 35 revolves around the screw 34 when the oscillating drive gear 31 rotates. As shown in FIG. 2, the maximum outer diameter locus L drawn by the convex portion 35 during the revolution of the convex portion 35 is located on the inner side along the radial direction of the oscillating drive gear 31 with respect to the tooth bottom 31 a of the oscillating drive gear 31. .

  The slider 32 has a plate shape extending in the height direction of the reel body 2. The slider 32 is fixed to the rear end of the spool shaft 12 via a screw 36 so as to be positioned between the oscillation drive gear 31 and the rotor drive gear 21.

  The slider 32 has a boss portion 37 at the center along the vertical direction. The boss portion 37 projects from the left side surface of the slider 32 toward the rotor drive gear 21, and the rear end of the spool shaft 12 is fitted into the boss portion 37 so as to be relatively non-rotatable. Therefore, most of the slider 32 is interposed between the rear end of the spool shaft 12 and the oscillating drive gear 31, and the slider 32 and the oscillating drive gear 31 are adjacent to each other in the width direction of the reel body 2. .

  A guide groove 39 is formed on the surface of the slider 32 facing the oscillation drive gear 31. The guide groove 39 extends linearly along the height direction of the reel body 2 so as to be orthogonal to the rear end of the spool shaft 12, and the convex portion 35 of the oscillating drive gear 31 slides inside the guide groove 39. It fits movably.

  When the handle 26 is operated in the direction of winding the fishing line, the rotation of the rotor driving gear 21 is transmitted to the oscillating driving gear 31 via the relay gear 23, and the oscillating driving gear 31 rotates. Due to the rotation of the oscillating drive gear 31, the convex portion 35 revolves around a screw 34, and apparently the convex portion 35 moves up and down along the guide groove 39.

  As a result, the rotational motion of the oscillating drive gear 31 is converted into a reciprocating linear motion by the fitting of the convex portion 35 and the guide groove 39 and transmitted to the slider 32. Since the slider 32 is fixed to the rear end of the spool shaft 12, the slider shaft 12 reciprocates in the front-rear direction of the reel body 2 so as to be orthogonal to the handle shaft 25 together with the spool 14.

  As shown in FIGS. 1 and 2, the guide shaft 33 is supported by the bottom wall 4 b of the case 4. The bottom wall 4 b of the case 4 has a pair of bearing portions 41 a and 41 b protruding into the accommodation chamber 6. One bearing portion 41 a is located at the front end of the case 4, and the other bearing portion 41 b is located at the rear end of the case 4. The guide shaft 33 is inserted into the accommodation chamber 6 so as to straddle between the bearing portions 41 a and 41 b from the direction of the front end of the case 4. The front end of the guide shaft 33 is fixed to the case 4 via an E ring 42, for example.

  The guide shaft 33 is disposed below the slider 32 and in parallel with the spool shaft 12. A slide groove 43 extending in the axial direction of the guide shaft 33 is formed in the lower end portion 32 a of the slider 32. The sliding groove 43 covers the guide shaft 33 so as to be slidable. Therefore, the slider 32 is supported between the spool shaft 12 and the guide shaft 33 that are parallel to each other.

  As best shown in FIG. 2, the guide shaft 33 is disposed outside the maximum outer diameter locus L drawn by the revolving convex portion 35 below the slider 32. Further, when the guide shaft 33 is viewed from the axial direction of the handle shaft 25, a part of the guide shaft 33 overlaps with the outer peripheral portion of the oscillating drive gear 31.

  In other words, at the position where the guide shaft 33 overlaps with the outer peripheral portion of the oscillating drive gear 31, the upper portion of the guide shaft 33 is more oscillated than the tooth tip 31b defining the outer peripheral edge of the oscillating drive gear 31, as shown in FIG. It is located inside 31 along the radial direction. Therefore, the groove bottom 43a of the sliding groove 43 with which the guide shaft 33 contacts is positioned above the tooth tip 31b by an amount corresponding to the distance H.

  According to such a configuration, the slider 32 that reciprocates linearly in the axial direction of the spool shaft 12 is supported by the spool shaft 12 and the guide shaft 33 that are parallel to each other. The spool shaft 12 and the guide shaft 33 are The reel body 2 is separated in the vertical direction. For this reason, when the slider 32 moves, rattling of the slider 32 in the direction intersecting the moving direction and the rotation direction of the oscillating drive gear 31 can be eliminated, and the movement of the slider 32 becomes smooth.

  In addition, according to the above configuration, the guide shaft 33 that guides the moving direction of the slider 32 is located outside the maximum outer diameter locus L drawn by the revolving convex portion 35 below the spool shaft 12, and this guide shaft A part of 33 overlaps with the outer periphery of the oscillating drive gear 31.

  For this reason, the guide shaft 33 can be arranged using a dead space generated below the slider 32, and the guide shaft 33 can be prevented from projecting greatly below the oscillating drive gear 31.

  Therefore, although the slider 32 is supported by both the spool shaft 12 and the guide shaft 33, the guide shaft 33 can be compactly disposed in the vicinity of the outer peripheral portion of the oscillating drive gear 31. Therefore, the reel main body 2 can be reduced in size and weight, and an easy-to-use fishing spinning reel 1 can be obtained.

FIG. 5 discloses a second reference example of a fishing spinning reel relevant to the present invention.

The second reference example is different from the first reference example in the relative positional relationship between the oscillating drive gear 31, the slider 32, and the guide shaft 33. Other configurations of the spinning reel 1 for fishing are the same as those in the first reference example .

  As shown in FIG. 5, the guide shaft 33 is disposed directly below the spool shaft 12 so as to avoid the lower end of the guide groove 39 of the slider 32. At the same time, the guide shaft 33 is located between the lower end of the convex portion 35 and the tooth tip 31b of the lower end of the oscillating drive gear 31 when the convex portion 35 of the oscillating drive gear 31 is located at the lower end of the guide groove 39. Yes.

Therefore, when compared with the position of the guide shaft 33 of the first reference example shown by the two-dot chain line in FIG. 5, the guide shaft 33 is displaced upward from the lower end of the oscillating drive gear 31.

  The slider 32 has a bearing portion 51 that projects to the opposite side of the oscillating drive gear 31 at the lower end portion 32a. The bearing portion 51 protrudes into a dead space between the rotor drive gear 21 and the slider 32, and is located just below the boss portion 37 into which the rear end of the spool shaft 12 is fitted.

  Furthermore, a sliding groove 43 that opens downward is formed on the lower surface of the bearing portion 51. The sliding groove 43 extends in the axial direction of the guide shaft 33. The guide shaft 33 is fitted in the sliding groove 43 so as to be slidable in the axial direction.

  According to such a configuration, the guide shaft 33 is displaced upward from the lower end of the oscillating drive gear 31, so that the bottom wall 4 b of the case 4 can be brought closer to the oscillating drive gear 31 and the slider 32. For this reason, the extension of the case 4 below the oscillating mechanism 30 can be suppressed, and the reel unit 2 can be formed more compact in the vertical direction.

6 to 8 disclose a first embodiment of the present invention.

In the first embodiment of the present invention, the positional relationship between the spool shaft 12 and the slider 32 is different from that of the first reference example . Other configurations of the spinning reel 1 for fishing are the same as those in the first reference example .

  As shown in FIG. 6, the slider 32 has a boss portion 61 that protrudes forward from its front end. The rear end of the spool shaft 12 is fitted into the boss portion 61 from the front of the slider 32 and is fixed to the boss portion 61 via a screw 62. The screw 62 is screwed into the boss portion 61 from the left side of the slider 32.

  Further, when the spool shaft 12 is viewed from the axial direction, a part along the radial direction of the spool shaft 12 overlaps the guide groove 39. Accordingly, the guide groove 39 is positioned on the extension of the axis O1 of the spool shaft 12, and the eccentric amount of the slider 32 along the radial direction of the spool shaft 12 is suppressed to be small.

  As shown in FIGS. 6 and 8, a bearing portion 63 that supports the intermediate portion of the spool shaft 12 is formed in the case 4 of the reel body 2. The bearing portion 63 includes a bearing hole 64 through which the spool shaft 12 passes. The bearing hole 64 includes a first portion 65, a second portion 66 having a larger diameter than the first portion 65, and a third portion 67 having a larger diameter than the second portion 66. is doing. The first to third portions 65 to 67 are coaxial with each other and are arranged in the axial direction of the spool shaft 12, and the rear end of the pinion gear 11 enters the inside of the third portion 67.

  A cylindrical collar 68 is interposed between the bearing hole 64 and the spool shaft 12. The collar 68 is press-fitted inside the first portion 65 of the bearing hole 64, and its front end abuts against the rear end surface of the pinion gear 11. The spool shaft 12 penetrates the inside of the collar 68 so as to be slidable in the axial direction.

  A first ball bearing 70 is interposed between the second portion 66 of the bearing hole 64 and the outer peripheral surface of the collar 68. The first ball bearing 70 supports the collar 68 rotatably. Further, a second ball bearing 71 is interposed between the third portion 67 of the bearing hole 64 and the outer peripheral surface of the rear end of the pinion gear 11. The second ball bearing 71 rotatably supports the rear end of the pinion gear 11.

  According to such a configuration, when the spool shaft 12 is viewed from the axial direction, a portion along the radial direction of the spool shaft 12 overlaps the guide groove 39, and the amount of eccentricity of the slider 32 along the radial direction of the spool shaft 12 is small. It is suppressed. For this reason, the spool shaft 12 and the slider 32 can be compactly arranged in the axial direction of the handle shaft 25, and the reel body 2 can be formed narrower.

  According to the above configuration, in addition to the smooth movement of the slider 32 and the smooth winding operation of the fishing line, the spool shaft 12 also has the reel main body 2 via the collar 68 and the first ball bearing 70. It is supported by the bearing portion 63 so that unnecessary friction is less likely to act on the spool shaft 12.

  For this reason, the support structure for the spool shaft 12 is applied to the fishing spinning reel 1 having a drag mechanism (rear drag) that applies a braking force in the rotational direction of the spool shaft 12 that rotates integrally with the spool 14, for example. Therefore, the drag performance is further improved.

FIG. 9 discloses a second embodiment of the present invention.

In the second embodiment, the inner ring 70a of the first ball bearing 70 is directly press-fitted into the outer peripheral surface of the spool shaft 12, and the other configuration is the same as that of the first embodiment.

According to this configuration, the collar 68 used in the first embodiment is not necessary, and the number of parts of the fishing spinning reel 1 can be reduced. Therefore, the cost of the fishing spinning reel 1 can be reduced while improving the drag performance as in the first embodiment, and an inexpensive fishing spinning reel 1 can be provided.

FIG. 10 discloses a third embodiment of the present invention.

In the third embodiment, the second ball bearing 71 is mounted across the first ball bearing 70 and the rear end of the pinion gear 11. Therefore, the first ball bearing 70 and the second ball bearing 71 are fitted inside the bearing hole 64 so as to overlap each other.

  According to such a configuration, since the first ball bearing 70 and the second ball bearing 71 are coaxially overlapped, the thickness dimension of the bearing portion 63 along the axial direction of the spool shaft 12 can be reduced. Therefore, there is an advantage that the bearing 63 can be reduced in size, which is advantageous in reducing the size and weight of the reel body 2.
