Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a sliding mechanism for a fishing reel.

[0002]

2. Description of the Related Art Conventionally, as a sliding mechanism of a fishing reel, a mechanism described in Japanese Patent Publication No. 2-60295 is known. This is fixed to the handle shaft that extends in the left-right direction of the reel unit, the oscillating gear that is linked to the rotation of the handle shaft that is supported by a shaft that is parallel to the handle shaft, and the spool shaft that extends slidably in the front-rear direction of the reel unit. Vertical groove provided in the oscillator in contact with the oscillating gear, a long hole provided in the radial direction of the oscillating gear, and an elliptical shape long in the front-rear direction on the reel body so as to surround the oscillating gear shaft. The cam groove is provided with a pin that penetrates the elongated hole and has one end inserted into the cam groove and the other end inserted into the vertical groove.

In this fishing reel, when the handle shaft is rotated, the oscillating gear rotates, and the pin that has entered the elongated hole follows the elliptical cam groove into which one end of the oscillating gear is inserted. Perform an elliptical turning motion while moving to. Since the other end of the pin is inserted in the longitudinal groove of the oscillator, the oscillator reciprocates back and forth following the elliptical turning motion of the pin. Therefore, the spool shaft and the spool attached to the tip of the spool shaft also reciprocate forward and backward in front of the reel body.

[0004]

However, in the above-mentioned conventional sliding mechanism for fishing reels, since the pin is only inserted into the long hole and the cam groove of the oscillating gear, It tends to incline, the smoothness of the movement of the transmission system from the oscillating gear to the oscillator is impaired, and the spool also rattles in the front-rear direction, which hinders the winding of the fishing line. In addition, when a shock load is applied to the spool due to a fall of the reel or the like, a large force is applied to the pin via the spool shaft, so that the pin is easily twisted or damaged. Also, the direction of the cam groove must match the direction of the spool shaft,
There are restrictions on the shape of the reel unit and the arrangement of parts. Furthermore, since the pin has to be provided inside the root circle of the oscillating gear, the stroke of the oscillator or spool cannot be increased. Furthermore, while the pin is constrained by an elliptical cam groove that is flat in the top and bottom and long in the front and back,
Even if the oscillating gear that rotates at a constant angular velocity moves in the radial direction and makes an elliptic motion, the sliding amount per rotation angle of the oscillating gear is large at the vertical position of the oscillating gear. Since it intersects with the sliding direction of the oscillator, the amount of sliding per rotation angle of the oscillating gear becomes small, so there is a problem that the pin cannot be rapidly slid at the front and rear ends thereof.

Therefore, an object of the present invention is to provide a fishing reel sliding mechanism which can solve such problems.

The master gear 8 and a pinion 9 that is integrally formed with the cylinder shaft of the rotary frame 2 that meshes with the master gear 8 are provided. Therefore, when the handle 5 is rotated by the operator of the fishing reel, the rotation is sequentially transmitted from the handle shaft 5a to the handle shaft cylinder 7, the master gear 8 and the pinion 9, and the rotating frame 2 rotates. Become.

The transmission device for sliding the spool 4 back and forth is the handle shaft cylinder 7 extending in the left-right direction of the reel body 1 and the spool supported by the reel body 1 slidably in the front-back direction. An oscillator 12 fixed to the rear end of the shaft 3, a vertical groove 19 provided in the oscillator 12 in the vertical direction, and a connecting gear 21 integral with the handle shaft cylinder 7 provided in the reel body 1 are drive-connected. An oscillating gear 11 rotatably supported around the oscillating gear shaft 10 of the reel body 1, and a pin guide slot 17 provided in the radial direction of the oscillating gear 11.
The substantially elliptical cam groove 18 provided on the side wall of the reel body 1 facing the oscillating gear 11 and the pin guide elongated hole 17 slidably pass through, and one end 15a is engaged with the cam groove 18. The other end 15b has a pin 15 engaged with the vertical groove 19. Further, in such a structure, the pin guide elongated hole 17 is provided so as to obliquely intersect the radial direction of the oscillating gear 11, and the cam groove has a substantially elliptical major axis that slides on the spool shaft. It is provided so as to cross the direction diagonally.

The spool shaft 3 supports the spool 4 at the tip end side of a spool shaft 12 which penetrates the pinion 9 which supports the rotary frame 2 and projects to the front of the rotary frame 2, and is screwed by a drag knob 40 so as not to fall off. I'm wearing it. The oscillator 12 is fixed to the rear end of the spool shaft 3 with a screw 20. The oscillator 12 is long in the vertical direction of the reel unit 1 and has a shape that prevents the spool 12 from rotating. The surface facing the oscillating gear 11 is a flat surface, and the vertical groove 19 is formed on the flat surface.

The oscillating gear 11 meshes with the connecting gear 21 formed on the handle shaft cylinder 7, and rotates around the oscillating gear shaft 10 in conjunction with the rotation of the handle shaft cylinder 7. The pin guide slot 17 provided in the oscillating gear 11 is, as shown in FIG.
7 is formed such that a radial line p in the longitudinal direction intersects the semi-meridian line r of the oscillating gear 11 on the oscillating gear 11 at the angle α ₁ so that the outer diameter side portion precedes the inner diameter side portion in the forward rotation direction X thereof. ing.

As shown in FIG. 4, the cam groove 18 has a substantially elliptical shape, and the center line r on the major axis of the cam groove 18 rotates in the forward direction of the oscillating gear 11 with reference to the sliding direction L of the spool shaft 3. It is inclined so as to precede the direction X by an angle β ₁ .
With the rotation of the oscillating gear 11, the pin 15 makes a motion close to a constant velocity as described later while being regulated by both the cam groove 18 and the pin guide elongated hole 17, and the spool shaft 3 also moves substantially in the sliding direction L thereof. You will move at a constant speed.

The pin 15 is a round shaft, and is shown in FIGS.
As shown in FIG. 5, the oscillator gear 11 penetrates in the left and right direction at the pin guide elongated hole 17, one end 15a thereof engages with the cam groove 18, and the other end 15b thereof penetrates the longitudinal groove 1 of the oscillator 12.
9 is engaged.

Next, the operation of the sliding mechanism of the fishing reel will be described. When the handle 5 is turned, the handle barrel 7 rotates and the rotary frame 2 rotates via the transmission as described above, and at the same time, the oscillating gear 11 rotates.
When the oscillating gear 11 rotates, the pin 15 engaged with the oscillating gear 11 moves along the groove hole of the cam groove 18 while being conveyed to the oscillating gear. Since the other end 15b of the pin 15 is fitted in the vertical groove 19 of the oscillator 12, the oscillator 12 makes a reciprocal sliding motion back and forth. This reciprocating sliding motion corresponds to the displacement curve m drawn by the broken line in FIG. 6, which is approximate to the constant velocity motion line n represented by the solid line in FIG.

That is, the quadrant II and the quadrant IV in FIG. 4 correspond to the vertical position of the oscillating gear, and in that range, the moving direction of the pin 15 and the sliding direction of the oscillator coincide with each other, so the spool per rotation angle of the oscillating gear. The sliding amount is large and the spool slides at high speed. However, as shown in FIG. 4, when the pin 15 on the cam groove 18 is in the II quadrant or the IV quadrant, the pin 15 is regulated by both the cam groove 18 and the pin guide elongated hole 17, and the moving amount Y ₁ , Y ₂ are generated, and the pin 15 moves in the diameter reducing direction of the oscillating gear 11 due to Y _1, and at the same time the forward rotation direction X of the oscillating gear 11 is generated.
And move in the opposite direction. As a result, as shown in FIG. 6, the oscillator 12 moves in the high-speed sliding range in the region from the point a to the point b (II quadrant) and the region from the point c to the point d (IV quadrant) on the displacement curve. The vehicle is decelerated, and the displacement curve m approaches the constant velocity motion line n.

On the other hand, the I and III quadrants in FIG. 5 correspond to the front and rear positions of the oscillating gear, and within that range, the pin 15 is used.
Since the moving direction of the oscillator intersects the sliding direction of the oscillator, the sliding amount per rotation angle of the oscillating gear becomes small, and the pin 15 cannot slide rapidly at the front and rear ends of the oscillating gear. However, as shown in FIG.
When the upper pin 15 is in the I or III quadrant, pin 1
Numeral 5 generates movement amounts Z ₁ and Z ₂ under the restriction of both the cam groove 18 and the pin guide elongated hole 17, and the pin 15 moves in the radial direction of the oscillating gear 11 by Z ₁ and at the same time the oscillating gear 11 moves. Move in the forward direction X. As a result, the area from point b to point c on the displacement curve in FIG. 6 (III quadrant)
And the pin 15 is accelerated in the X direction in the low-speed sliding range, which is the range from the d point to the a point (I quadrant), therefore,
The oscillator 12 is also accelerated, and its displacement curve m approaches the constant velocity motion line n.

As described above, the displacement curve m of the oscillator 12 approaches the constant velocity motion line n as a whole, and the oscillator 1
2 and thus the spool 4 makes a reciprocal sliding motion in the front-rear direction at a speed close to a constant speed, so that the fishing line is wound evenly over the entire width of the spool 4.

[0018]Embodiment 2 As shown in FIG. 7, the oscillating gear 11 is provided with
The radial line p of the pin guide elongated hole 17 is an oscillating gear.
11 above the outer diameter side portion of the inner diameter side portion in the forward rotation direction X
The radius line q of the oscillating gear 11
Degree α_TwoIt is formed as if it intersects at. Also, the cam groove
18 is the center line r on the major axis of the spool shaft 3 sliding direction
The direction opposite to the forward rotation direction X of the spool gear 11 with reference to L
At angle β _TwoIt is only inclined to follow.

As the oscillating gear 11 rotates, the pin 15 is regulated by both the pin guide elongated hole 17 and the cam groove 18, so that the pin 15 and the spool shaft 3 reciprocate in the direction of the spool shaft 3 at a substantially constant speed. Will be done. That is, the pin 15 on the cam groove 18 is the I quadrant or II.
When in the I quadrant, the pin 15 generates movement amounts Z ₁ and Z ₂ under the restriction of both the cam groove 18 and the pin guide elongated hole 17, and the pin 15 moves in the radial direction of the oscillating gear 11 by Z _1. The forward rotation direction X of the oscillating gear 11 at the same time as it moves
Go to As a result, the oscillator 12 is accelerated in the low-speed sliding range, and the displacement curve m approaches the constant velocity motion line n (see FIG. 6). On the other hand, although not shown, when the pin is in the II or IV quadrant on the cam groove 18,
The pin 15 moves in the diameter reducing direction of the oscillating gear 11 under the control of both the cam groove 18 and the pin guide elongated hole 17, and at the same time, moves in the direction opposite to the forward rotation direction X of the oscillating gear 11. As a result, in the high-speed sliding range, the oscillator 12
Is decelerated, and its displacement curve m approaches the constant velocity motion line n (see FIG. 6).

Therefore, the displacement curve m of the oscillator 12 approaches the constant velocity motion line n as a whole, and the oscillator 1
2 makes a stable reciprocating constant-velocity sliding motion forward and backward, and the spool 4 also makes a reciprocating constant-velocity motion forward and backward in conjunction with the rotation of the rotary frame 2.

Embodiment 3 As shown in FIG. 8, the pin guide elongated hole 17 in the sliding mechanism of the fishing reel has a pin guide elongated hole 17 near both ends 17a, 1.
7b and an intermediate portion 17c between the end portions 17a, 17b. Of which is formed to ride in the middle portion 17c on i.e. radial line as the center line p _c is eliminated intersection angle to the radius line q of the oscillating gear 11. The center lines p of the ends 17a and 17b are close to each other.
_a and p _b are parallel to each other and are formed so as to intersect with the radial direction q of the oscillating gear 11 at predetermined intersecting angles α ₃ and α ₄ .

As a result, in the sliding range of the spool shaft 3,
It is possible to accelerate and decelerate at the front and rear ends and the center and not accelerate and decelerate at other points. The intermediate portion 17c of the pin guide elongated hole 17 may be provided with a crossing angle, and the crossing angles α ₃ and α ₄ of the both ends 17a and 17b may be the same or different from each other. .

It is connected via 28a. As a result, the elliptical movement of the pin 15 along the cam groove 18 is converted into the sliding movement of the spool shaft 3 through the swinging movement of the link 28 around the fulcrum pin 28c.

In this case, the sliding amount of the oscillator 12 can be enlarged or reduced by changing the distance between the fulcrum pin 28c, the other end 15b of the pin 15 and the oscillator 12, and therefore the spool winding portion of the spool 4 can be expanded or reduced.

The link 28 can swing about the other end 15b of the pin 15 as a fulcrum, and the boss 28e projecting like a pin from the reel body 1 and the pin-like oscillator 12 enter into the elongated hole 28d provided in the link 28, respectively. I'm out. As a result, the elliptical motion of the pin 15 along the cam groove 18 is converted and transmitted from the oscillator 12 to the spool shaft 3 into a constant-velocity sliding motion through the swinging motion of the link 28 around the boss 28e.

The boss 28e and the other end 15b of the pin 15 are
And the distance between the oscillator 12 and the boss 28

Has been formed.

To prevent the pin 15 from rotating with respect to the pin guide elongated hole 17, the parallel flat surface 15 formed on the side surface of the pin 15 is used.
This is done by abutting c on the parallel inner surface of the pin guide elongated hole 17. As a result, the rotary plate 13 (see FIG.
(See) can be omitted.

Fifteenth Embodiment As shown in FIGS. 25 and 26, the pin 15 includes an oscillator 12 (see FIGS. 1 and 2) or a link 28 (see FIG. 9).

When one end 15a of the pin 15 is in the II quadrant (or IV quadrant), the rotation of the oscillating gear 11 in the forward rotation direction X causes the one end 15a of the pin 15 to move in the diameter reducing direction by the movement amount Y ₁ and at the same time in the direction X. It moves in the opposite direction to the moving amount Y ₂ and decelerates. Further, the deceleration effect can be obtained by the moving amount Y ₂ since also the other end 15b of the pin to move by the amount of movement Y _2. Therefore, the displacement curves of the oscillator are closer to the constant velocity motion line in the II quadrant and the IV quadrant due to the movement amounts Y ₂ and Y ₃ . Next, one end 1 of the pin 15
When 5a is in the I quadrant (or the III quadrant), the rotation of the oscillating gear 11 in the forward rotation direction X causes the one end 15a of the pin 15 to move in the acceleration direction by the movement amount Z ₂ . Similarly, the other end 15b of the pin is also (not shown) move Z ₃ in the same direction as the direction X by moving. Therefore, the displacement curves of the oscillator become closer to the lines of constant velocity in the I quadrant and the III quadrant due to the movement amounts Z ₂ and Z ₃ . Thus, the oscillator 12 that engages with the other end 15b of the pin 15
Per one rotation of the oscillating gear 11, the spool 4 reciprocates at a speed close to a constant speed, as it moves along a motion curve similar to the constant speed movement line shown by the broken line in FIG.

The other end 15b of the pin 15 is connected to the one end 15a.
Even if the cam groove 18 and the pin guide slot 17 are angularly biased as shown in FIG. 7, the same effect as described above can be obtained.

[0047]

According to the invention of claim 1, the following effects can be obtained.

The degree of freedom in design regarding the shape of the reel body, the arrangement of parts, etc. is increased, and the reel body can be made smaller and lighter.

According to the second aspect of the present invention, the pin guide elongated hole is divided into at least three parts in the lengthwise direction, and at least the central portion of the pin guide elongated hole intersects with the radial direction of the oscillating gear at an intersecting angle in other portions. Since they are formed differently, it is possible to partially change and adjust the sliding speed of the oscillator and thus the spool.

According to the invention of claim 3, since the other end of the pin and the oscillator are connected by the link, the cam groove,
The shape of the oscillator etc., the positional relationship between the cam groove and the oscillator with respect to the reel unit, etc. can be changed as appropriate.
Therefore, the degree of freedom in design is increased, and the reel can be made smaller and lighter. Further, the drive transmission resistance of the other end of the pin with respect to the oscillator can be reduced, and the sliding movement of the spool can be made smoother.

According to the invention of claim 4, the link is axially supported by any one of the other end of the pin, the oscillator and the reel unit, and the other two are connected to the link through a long hole. Therefore, the amount of sliding of the oscillator with respect to the elliptic motion of the pin can be expanded or reduced by changing the shape, orientation, etc. of the link, slot, etc. appropriately, and the sliding amount can be adjusted according to the width of the bobbin winding body of the spool. The amount of movement can be adjusted. Further, the sliding speed of the oscillator and thus the spool can be partially changed and adjusted by appropriately changing the shape and angle of the elongated hole of the link.

According to the invention of claim 5, a rotary plate is provided side by side with the oscillating gear so as to be rotatable together with the oscillating gear and slidable in the direction of the elongated hole, and one end of the pin is provided on each side of the rotary plate. Since the other end is provided, the pin is less likely to be tilted, the motion conversion from the oscillating gear to the oscillator and the drive transmission are smoothly and reliably performed, and the fishing line can be properly wound by the spool. Further, since the pin is supported by the rotating plate, the pin is less likely to be damaged even if an impact force is applied to the spool.

According to the invention of claim 6, the pin is formed so that the other end engaged with the oscillator or the link is displaced in the radial direction of the oscillator gear with respect to the one end engaged with the cam groove. By preparing a plurality of types of rotary plates having different amounts of deviation, it is possible to cope with changes in the amount of sliding of the spool by exchanging them according to the size of the width of the spool. Further, by biasing the other end of the pin larger than the major axis of the cam groove, it is possible to secure a spool sliding amount equal to or larger than the diameter of the oscillating gear. Therefore, a small oscillating gear and cam groove provide a large sliding amount of the spool. be able to.

According to the seventh aspect of the present invention, the pin is formed so as to be able to slide in the pin guide elongated hole while being prevented from rotating, and the other end of the pin that engages with the oscillator or the link has a cam groove. Since it is formed so as to be deviated in the radial direction of the oscillating gear with respect to one end engaged with, the same effect as when the rotary plate is provided without providing the rotary plate is obtained.

According to the invention of claim 8, the pin is formed so that the other end engaged with the oscillator or the link is biased in the circumferential direction of the oscillator gear with respect to the one end engaged with the cam groove. By changing the amount of bias appropriately,
The ratio of the major diameter to the minor diameter of the cam groove can be adjusted to bring the cam groove closer to, for example, a perfect circle to smooth the movement of the pin along the cam groove and the sliding movement of the spool. Further, it is possible to prevent wear and damage of the cam groove and the pin.
