Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a reciprocating device for a spinning reel, and more particularly to a fishing line take-up spool fixed to a tip of a spool shaft of a reel, which is reciprocated back and forth in conjunction with rotation of a handle. The present invention relates to a reciprocating device for a spinning reel that winds the reel on the outer peripheral surface of the spool.

[0002]

[Prior art]

 In a conventional spinning reel, a reciprocating device for reciprocating a spool mainly includes a gear member 1 and a slider member 2 as shown in FIGS. The gear member 1 is rotatably supported in a reel frame 4 so as to mesh with a driving gear 302 provided on the outer periphery of a rotating shaft 301 of the handle 3, and a projection 101 is formed at an eccentric portion on one surface thereof. Have been. The slider member 2 is fixed to a rear end of a spool shaft 501 on which the spool 5 is mounted at a front end, and has an engagement groove which engages with the projection 101 on a surface facing the gear member 1. 201 is formed.

When the gear member 1 is rotated in conjunction with the rotation of the handle 3, the reciprocating device having the above-described configuration engages with the projection 101 and the engagement groove 201 to cause the gear member 1 to rotate. Can be changed to the linear motion of the slider member 2, and the slider member 2 and the spool 5 can be reciprocated back and forth (left and right in FIG. 8).

[0004]

[Problems to be solved by the invention]

 However, such a reciprocating device changes the rotational motion of the circular gear member 1 into a linear motion, so that the reciprocating speed of the spool 5 changes with trigonometric functions symmetrical to each other. In other words, both the forward (forward) speed and the backward (backward) speed are slow near both ends and fast in the middle. As a result, at both ends of the spool 5, more fishing line is wound and higher than at the center, and as a result, the raised fishing line at both ends collapses toward the center, and the fishing lines are entangled with each other. Easy to occur.

The reciprocating stroke of the spool 5 is related to the radius of the rotation trajectory of the projection 101, that is, the distance from the projection 101 to the rotation axis of the gear member 1. Becomes larger, the reciprocating stroke of the spool 5 becomes larger, and as the radius of the rotation trajectory becomes smaller, the reciprocating stroke of the spool 5 becomes smaller. However, in the conventional reciprocating device, the amount of increase in the reciprocating movement of the spool 5 is only twice the amount of increase in the radius of the rotation locus, and the protrusion 101 has a limited space. However, there is a drawback that the range of the reciprocating movement stroke that can be adjusted is considerably limited because it is restricted in the engagement groove 201.

Accordingly, it is a first object of the present invention to provide a reciprocating device for a spinning reel capable of improving the spool winding shape. It is a second object of the present invention to provide a reciprocating device for a spinning reel that can increase the range in which the reciprocating stroke of the spool can be adjusted.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, the reciprocating device for a spinning reel according to the present invention reciprocates a fishing line winding spool fixed to a tip portion of a spool shaft back and forth in conjunction with rotation of a handle. A reciprocating device for a spinning reel that winds the reel on the outer peripheral surface of the spool, is provided on a support shaft so as to rotate in conjunction with the rotation of the handle, and is provided with an eccentric portion on one surface thereof. A gear member provided with a portion, a slider member fixed to a rear end of the spool shaft, and a second engagement portion provided on a surface facing the gear member; The swingable end is rotatably supported between the gear member and the slider member, and the swingable one end is engaged with the first engagement portion and the second engagement portion. Third and fourth engaging portions are provided, respectively. A swinging member which is rotated when the gear member is rotated in conjunction with the rotation of the handle, by the engagement between the first engagement portion and the third engagement portion. The swing member swings back and forth along the reciprocating direction of the spool, and the slider member and the spool are moved back and forth by engagement of the second engagement portion and the fourth engagement portion. To reciprocate.

The difference between the reciprocating device of the present invention having the above configuration and the conventional reciprocating device is that a swing member is provided between the gear member and the slider member. As a result, the speed change of the forward movement (forward movement) and the backward movement (retreat) of the spool becomes asymmetric, so that the winding position of the fishing line around the spool during the forward movement and the backward movement is shifted. As a result, the density of the fishing line wound around the spool can be increased, the height of the fishing line wound around can be averaged, and the line winding shape of the spool can be improved. That is, it is possible to reduce the problem that the fishing line is wound more at both ends of the spool than at the center as in the conventional case.

Further, according to the reciprocating device, the slider member does not directly interlock with the rotational movement of the gear member, but indirectly interlocks with the rotational movement of the gear member via the swing member. And reciprocate. Therefore, the amount of change in the reciprocating movement of the spool can be increased to twice to several times or more the amount of change in the radius of the rotation locus. As a result, the range in which the reciprocating stroke of the spool can be adjusted can be increased.

[0010] In the reciprocating device, the first and second engagement portions are projections that protrude from the one surface of the gear member and the surface of the slider member facing the one surface, respectively. It is preferable that the third and fourth engagement portions are engagement grooves formed in the one end of the swing member, respectively.

In this case, the engagement groove is a pair of long grooves provided so that their major diameters are along one of the radiations extending from the pivot point of the rocking member and are located at a predetermined angular distance from each other. Is preferred.

Alternatively, in the reciprocating device, a sun gear provided on the support shaft of the gear member, a first engagement portion of the gear member, and a third engagement portion of the swing member And a planetary gear that engages with the first engagement portion of the gear member so that the planetary gear rotates around the sun gear while rotating around the sun gear as the gear member rotates. You may comprise so that it may be supported by a shaft, and one end may mesh with the said sun gear.

[Embodiment of the invention]

 Hereinafter, embodiments of the reciprocating device for a spinning reel according to the present invention will be described in detail. In the following description, components having substantially the same function and configuration will be denoted by the same reference numerals, regardless of their size, and repetitive description will be made only when necessary.

FIG. 1 shows a spinning reel using a reciprocating device according to a first embodiment of the present invention. The spinning reel mainly includes a frame 10, a handle 20, a rotor 30, a spool 40, and a bail 50.

The handle 20 is rotatably supported by the frame 10. The rotor 30 includes a cylindrical rotor main body 31 and a pair of rotor arms 32, 32 symmetrically extending from both sides of the rotor main body 31, and can rotate as the handle 20 rotates. As described above. The spool 40 is for winding the fishing line around its outer peripheral surface, and the reciprocating device 60 of the present invention interlocks with the rotation of the handle 20 to extend the axis of the rotor 30 in conjunction with the rotation of the handle 20. It is provided on one side of the rotor main body 31 so as to be able to reciprocate back and forth (left and right in FIG. 1) along the line. The bail 50 is swingably mounted on the pair of rotor arms 32, 32 so that the fishing line can be guided and wound around the spool 40.

The above configuration is substantially the same as the conventional spinning reel shown in FIG. 8, but the present invention is characterized by the configuration of the reciprocating device 60. Specifically, as shown in FIGS. 1 and 2, the reciprocating device 60 of the present invention has a gear member 61 and the slider member 62 as in the prior art, and the gear member 61 and the slider member This is different from the related art in that a rocking member 63 is further provided between the first and second members.

Hereinafter, a first embodiment of the reciprocating device 60 of the present invention will be described in detail. As shown in FIGS. 2 and 1, the spool 40 has a spool shaft 41. The handle 20 has a rotating shaft 21 extending in a direction perpendicular to the spool shaft 41. A drive gear 22 is provided on the outer periphery of the rotating shaft 21.

The gear member 61 is rotatably supported by a support shaft 612 in the frame 10 such that a gear surface at one end of the gear member 61 meshes with the drive gear 22, and an eccentric portion on one surface has a protrusion 611. (A first engagement portion) is formed. The support shaft 612 of the gear member 61 is configured to extend parallel to the rotation shaft 21 of the handle 2.

The slider member 62 is fixed to the rear end of a spool shaft 41 having the spool 40 mounted at the front end so that the slider member 62 is supported by the step portion 11 in the frame 10. A protrusion 621 (second engagement portion) is formed on the facing surface.

The other end of the swing member 63 is pivotally supported in the frame 10 so that one end of the swing member 63 can swing, and the swingable one end has a pair of engagement grooves. (Third and fourth engagement portions) 632 and 633 are formed.

The engagement groove 632 as the third engagement portion and the engagement groove 633 as the fourth engagement portion are formed of a pair of long grooves, as shown in FIG. It is provided along one of the radiations extending from the shaft fulcrum 631 of the moving member 63 so as to be located at a predetermined angular distance from each other. The length of the long groove of the third engaging portion (engaging groove 632) is longer than the length of the long groove of the fourth engaging portion (engaging groove 633).

The protrusion 611 (first engagement portion) is engaged with the engagement groove 632 (third engagement portion), and the protrusion 621 (second engagement portion) is It is engaged with the engaging groove 633 (fourth engaging portion). Here, as shown in FIG. 2, the position of engagement between the protrusion 611 and the engagement groove 632 is greater than the position of engagement between the protrusion 621 and the engagement groove 633. The shaft fulcrum 631 is approaching.

In the reciprocating device having the above-described configuration, when the gear member 61 is rotated about the support shaft 612 in association with the rotation of the handle 20, the protrusion 611 and the engagement groove 632 are moved. By the engagement, the circular rotational movement of the gear member 61 is changed to the oscillating movement of the oscillating member 63, and the oscillating member 63 is oscillated back and forth about the shaft fulcrum 631 as an axis. Further, the engagement between the projection 621 and the engagement groove 633 allows the slider member 62 to reciprocate back and forth in conjunction with the swing of the swing member 63.

Since the slider member 62 is fixed to the rear end of the spool shaft 41 of the spool 40, the slider member 62 reciprocates back and forth in conjunction with the swing of the swing member 63. Then, the spool 40 is also reciprocated back and forth.

Next, the operating principle of the reciprocating device of the first embodiment will be specifically described with reference to FIG. Note that a point O in FIG. 3 is a shaft center (support shaft 612) when the gear member 61 rotates, a circle A is a rotation locus of the protrusion 611 of the gear member 61, and a point D is The straight lines B and C are the pivot points 631 of the rocking member 63, and the straight lines B and C are the leftmost and rightmost ends of the rocking member 63 that are rocked by the engagement of the protrusion 611 and the engagement groove 632, respectively. Position. Points E and F are the contact points between the straight line B and the straight line C and the circle A, respectively. That is, point E can be regarded as the most advanced position (leftmost position) when the spool 40 moves forward and backward, and point F can be regarded as the most retreat position (rightmost position) when the spool 40 moves forward and backward. .

By dividing the circle A into two parts by connecting the points E and F with the point O, one has an angle M and the other has an angle N. Then, as shown in the figure, the angle N is somewhat larger than the angle M.

When assuming that the protrusion 611 is rotated clockwise, the rotation angle of the gear member 61 from the rightmost position (point F) to the leftmost position (point E) of the spool 40 is determined. Is the angle N, and the rotation angle of the gear member 61 from the leftmost position (point E) to the rightmost position (point F) is an angle M smaller than the angle N. Therefore, the speed change of the forward movement (forward movement) and the backward movement (retreat) of the spool 40 is asymmetric. That is, the speed change in the backward movement (from point E to point F) is faster than the speed change in the forward movement (from point F to point E).

Therefore, in the present embodiment, since the protrusion 611 makes a circular rotation, a problem arises in that more fishing line is wound at both ends of the spool 40 than at the center thereof. Since the speed change at the time of forward movement of the spool 40 and the speed change at the time of backward movement are asymmetric, the positions at which the fishing line is wound around the spool during the forward movement and the backward movement are shifted from each other. be able to.

As a result, the density of the fishing line wound on the spool 40 is increased, the height of the fishing line wound on the spool 40 is also averaged, the fishing line winding shape of the spool is improved, and the fishing lines on both ends are positioned at the center. The problem of collapsing and entanglement of fishing lines with each other can be greatly reduced. Also, by changing the position of the pivot point 631 (point D) of the swing member 63, the positions of the points E and F and the angles M and N can be changed.

According to this configuration, when the distance (radius of the circle A) from the protrusion 611 to the axis of the support shaft 612 of the gear member 61 is slightly increased by the similar triangle principle, the spool 40 When the radius of the circle A is slightly reduced, the reciprocating stroke of the spool 40 is reduced by a factor of two to several times.

As a result, in the present invention, the adjustable range of the reciprocating stroke of the spool 40 is considerably large. In addition, by changing the distance between the engagement point between the protrusion 611 and the engagement groove 632 and the engagement point between the protrusion 621 and the engagement groove 633, the reciprocating movement stroke can be changed. Can also.

In the first embodiment, the first and second engaging portions project from the one surface of the gear member 61 and the surface of the slider member 62 facing the one surface, respectively. And the third and fourth engagement portions are engagement grooves 632, 633 formed in the one end of the swing member 63, respectively. The first and fourth engagement portions may be protrusions, and the second and third engagement portions may be engagement grooves. Alternatively, the third and fourth engagement portions may be configured as engagement grooves. The first and second engagement portions may be projections, and the first and second engagement portions may be engagement grooves.

FIGS. 4 and 5 show a spinning reel using a reciprocating device 60 according to a second embodiment of the present invention. The second embodiment differs from the first embodiment in that a planetary gear mechanism is further provided.

Specifically, the planetary gear mechanism includes a sun gear 64 and a planetary gear 65. Here, the gear member 61 can be regarded as a planet frame. More specifically, as shown in FIG. 5, the sun gear 64 is provided integrally with the support shaft 612 of the gear member 61 so as not to rotate with the rotation of the gear member 61. On the upper surface of the planetary gear 65, a projection 652 as a fifth engagement portion is formed. The gear member 61 is engaged with an engagement groove 632 of the swing member 63 via a protrusion 652 of the planetary gear 65.

In the present embodiment, the first engaging portion of the gear member 61 is a convex pillar 613 formed as a shaft support, and the planetary gear 65 rotates with the rotation of the gear member 61. The gear member 61 is pivotally supported by the convex column 613 so as to rotate while revolving around the gear 64, and a gear portion 651 on one end of the gear member 61 meshes with the sun gear 64. Here, the protrusion 652 of the planetary gear 65 is arranged so that the axis thereof is shifted with respect to the convex column 613 of the gear member 61.

Hereinafter, the operation principle of the reciprocating device of the second embodiment will be described. As shown in FIG. 6, the planetary gear 65 revolves around the sun gear 64 while revolving with the rotation of the gear member 61, so that the rotation trajectory of the projection 652 of the planetary gear 65 is An ellipse P is obtained as shown in FIG. Further, similarly to the first embodiment, the straight lines B and C indicating the positions of the front and rear ends when the swing member 63 swings are set as tangents to the ellipse P, and the contacts E and F are obtained. After these contacts E and F are connected to the axis O (support shaft 612) point O at the time of rotation of the gear member 61, the ellipse P can be divided into two portions having different angles M and N.

Therefore, as in the first embodiment, the speed change at the time of forward movement of the spool 40 and the speed change at the time of backward movement are asymmetric, and the spool of the fishing line during the forward movement and at the time of backward movement is changed. It is possible to make the winding positions around to be shifted from each other. As a result, the density of the line to be wound on the spool 40 is increased, the height of the line to be wound is also reduced on average, the line winding shape of the spool is improved, and the line at both ends is formed in the central portion. The problem that the fishing line collapses and entangles each other can be greatly reduced.

In the second embodiment, as shown in FIG. 7, when the same angle J is rotated under the same reciprocating movement, the projection length, | P1−P2 | <| Q1-Q2 | The change in the stroke of the elliptical locus P per J angle is smaller than the change in the stroke of the circular locus A per J angle. Therefore, in the reciprocating device of the second embodiment, the fishing line can be more uniformly distributed on the outer peripheral surface of the spool 40 than in the first embodiment.

Here, point O is the revolving axis (support shaft 612) of the projection 652 of the planetary gear 65, and points H1 and H2 are the most forward end (left end) of the projection 652 at the time of revolution. ) And the rotation axis at the rearmost (rightmost) position. A line S2 is a distance from the protrusion 652 (point G1 or point G2) to the rotation axis (point H1 or H2), and a line S3 is the rotation axis (point H1 or point H2). Is the distance from to the orbital axis (point O). The line (S2 + S3) is the distance from the protrusion 652 (point G1 or point G2) to the revolution axis (point O).

In the second embodiment, when adjusting the reciprocating stroke of the spool 40, the size of the line (S2 + S3) can be adjusted in the same manner as in the first embodiment. In the embodiment, the size of the line S2 and the size of the line S3 can be adjusted as needed. That is, the forward and backward movement stroke of the spool 40 in the second embodiment has a larger adjustable range.

The reciprocating device for the spinning reel of the present invention is not limited to the configuration of the above-described embodiment. That is, in the above-described embodiment, the present invention has been made only with the intention of clarifying the technical contents of the present invention, and the present invention is not limited to such specific examples and is not interpreted in a narrow sense. The present invention can be implemented with various modifications within the scope stated in the purpose and the claims.

For example, in the second embodiment, the first engaging portion is a convex column 613 formed as a shaft supporting portion, and a lower surface of the planetary gear 65 is provided for supporting the convex column 613. Although the shaft hole is formed, the first engagement portion may be formed as a hole as a shaft support portion, and a convex column supported by the hole may be formed on the lower surface of the planetary gear 65.

When the structure of the second embodiment is adopted, the fishing line may be wound more at the center of the spool 40 than at both ends, but at that time, in order to improve the shape of the line winding, The above problem can be solved by forming the spool 40 so that the center portion is depressed inward from both ends as shown in FIG.
