Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spinning reel, and more particularly to a spinning reel having a line roller at the tip of an arm.

[0002]

A line roller of a spinning reel is provided on a bail support member which rotates together with a spool and swings between a line releasing position and a line winding position, and a fishing line comes into contact with an outer peripheral surface of the line roller. Be guided. When the fishing line is wound on the spool, the bail is swung to the line winding posture side, and when the handle is rotated, the fishing line is guided by the bail and comes into contact with the outer peripheral surface of the line roller, and is guided by the line roller to direct the fishing line in the direction of the fishing line. Is changed and it is wound around the outer circumference of the spool.

In the spinning reel, the fishing line spirals and is fed from the spool, so that the fishing line is twisted at this time. When the fishing line is wound on the spool, the fishing line is wound in the circumferential direction of the spool by being guided by the bale and the line roller from the axial direction of the spool, so that the fishing line is twisted in the opposite direction to that at the time of feeding.
If the same amount of twist is generated in the opposite direction at the time of delivery and at the time of winding, no twist will remain on the fishing line wound on the spool.

However, while the fishing line is being guided by the line roller, the fishing line may be excessively twisted due to the contact between the line roller and the fishing line. Specifically, the magnitude and direction of the force applied to the fishing line fluctuates due to the contact resistance with the line roller, and an unexpected twisting force or bending force is applied to the fishing line, causing the above-mentioned extra twist. As a result, twisting remains on the fishing line wound on the spool,
There arises a problem that it is difficult to smoothly feed the fishing line, and it becomes impossible to throw the fishing hook in the correct direction.

In Japanese Utility Model Laid-Open No. 6-46467, a groove is formed in the central portion of the outer peripheral surface of the line roller, and the fishing line is guided to the spool through the groove in order to prevent the above-mentioned twisting. The technique to do is shown.

[0006]

Even if the line roller is provided with the guide circumferential groove for guiding the fishing line as in the above-mentioned prior art, if the fishing line does not smoothly enter the guide circumferential groove,
The function of the guide groove cannot be fully exerted. The guide circumferential groove is relatively narrow and slightly wider than the diameter of the fishing line.
In order to smoothly guide the fishing line to such a narrow guide circumferential groove, it has been considered to provide guide surfaces for guiding the fishing line to the guide circumferential groove on both sides of the guide circumferential groove of the line roller.

However, if the guide surface is provided on the line roller in addition to the guide circumferential groove, the width of the line roller increases. As the width increases, so does the weight of the line roller. It is difficult to rotate a wide and heavy line roller lightly and smoothly, and it is difficult to balance the rotation of the line roller. If the rotation balance of the line roller is not balanced, the fishing line will not travel smoothly and the above-mentioned deviation will easily occur. If the line roller becomes large, the peripheral structure such as the bearing becomes complicated and the manufacturing cost increases.

It is an object of the present invention to reduce the weight and size of a line roller so that the fishing line can be smoothly guided.

[0009]

A spinning reel according to the present invention comprises a reel body, a rotor, a bail supporting member, a bail, a spool, a line roller, a fishing line guiding member and a fishing line guiding gap. The reel body has a handle and can be attached to a fishing rod. The rotor has first and second arm portions and is rotatably supported by the reel body. The bail support members are first and second bail support members that are swingably attached to the respective tip portions of the first and second arm portions. The bail is provided between the bail support members. The spool is arranged in front of the rotor, and the fishing line is wound around the outer periphery of the spool. The line roller is rotatably supported by one of the bail support members and has a guide circumferential groove for guiding the fishing line to the spool. The fishing line guide member is fixed to the bail support member on the side on which the line roller is supported, covers from the left and right sides of the guide circumferential groove of the line roller to a position adjacent to the peripheral edge of the guide circumferential groove, and faces the guide circumferential groove. A pair of left and right fishing line guiding members having a tapered peripheral surface with a reduced outer diameter.
The fishing line guide gap is formed between the pair of left and right fishing line guide members and has a width of 0.3 to 1.5 mm.

The basic structure of the reel body, the rotor, the bail support member, the spool, the line roller, etc. can be constructed by combining the structures of the respective members in a normal spinning reel. The line roller is made of metal, synthetic resin, ceramics, etc., and is made by means of casting, forging, rolling, pressing, cutting, etc., and has a substantially cylindrical shape, and through a rotary bearing such as a ball bearing or a slide bearing. Rotatably supported by the bail support member.

The guide circumferential groove is formed in a concave shape on the outer peripheral surface of the line roller. The width of the guide circumferential groove is set to be slightly larger than the diameter of the fishing line. Although it varies depending on the type of fishing line used in the spinning reel, normally, if the width of the guide circumferential groove is about 0.3 to 1.5 mm, the fishing line can be smoothly guided and twisting hardly occurs. Further, if the width of the guide circumferential groove is 3 to 20% of the diameter of the bottom portion of the guide circumferential groove, the above-mentioned function can be more effectively exhibited.

The guide circumferential groove may be a recess having a rectangular cross section, and if the left and right side walls of the guide circumferential groove are inclined, the fishing line is smoothly fed to the bottom of the guide circumferential groove. The bottom of the guide circumferential groove and the side wall or the upper edge of the side wall may be rounded or rounded.
The heights of the left and right side walls of the guide circumferential groove may be the same or different. If the height of the side wall on the bale side of the left and right side walls is lower than the height of the side wall on the opposite side, the fishing line is easily guided from the bale side to the guide circumferential groove, and the fishing line is guided. Prevents jumping out of the groove to the other side of the veil. On the contrary, if the height of the side wall arranged on the bale side is higher, it is easy to prevent the fishing line from jumping to the bale side.

The fishing line guide member is made of a structural material similar to that of the bail support member, such as metal, synthetic resin, or ceramic, and is integrally molded with the bail support member, or is bonded, fitted, screwed, etc. to the bail support member. It is attached by means. The fishing line guide member has a space for accommodating the line roller therein. The line roller can be supported by the fishing line guide member via a rotary bearing.

The fishing line guide members are arranged on both the left and right sides of the line roller, and cover from above the line roller to the left and right sides of the guide circumferential groove to a position adjacent to the peripheral edge of the guide circumferential groove. The adjacent position means a position that is close enough to be considered to be substantially coincident with the peripheral edge of the guide circumferential groove even if it is not exactly coincident with the peripheral edge of the guide peripheral groove. When there is a radius on the peripheral edge of the guide circumferential groove, the position of the virtual intersection between the side wall of the guide circumferential groove and the outer peripheral surface is used as a reference.

The line roller is arranged up to a position where it is covered by the left and right fishing line guiding members, and if the fishing line is surely fed from the fishing line guiding member into the guide circumferential groove of the line roller, it is more than that. It does not have to extend inside the fishing line guide member on the outside. The left and right fishing line guiding members may have the same shape, or may have different shapes according to their respective functions. For example, one fishing line guide member can be provided with a mounting structure for a bail support member, and the other fishing line guide member can be provided with a bail mounting structure.

The outer peripheral surface of the fishing line guide member is a tapered peripheral surface whose outer diameter decreases toward the guide circumferential groove. The inclination of the tapered peripheral surface is set to a relatively gentle inclination such that the fishing line can be smoothly guided from the left and right outer sides to the guide circumferential groove. The inclination angles of the left and right tapered peripheral surfaces may be the same or different. For example, the inclination angle of the tapered peripheral surface on the bale side can be made smaller than the inclination angle of the tapered peripheral surface on the opposite side.

The outer diameter of the inner peripheral edge of the peripheral surface disposed on the bale side of the left and right tapered peripheral surfaces can be made larger than the outer diameter of the inner peripheral edge of the peripheral surface disposed on the opposite side. As described above, when the left and right side walls of the guide circumferential groove have different heights, the inner peripheral edge outer diameter of the tapered peripheral surface adjacent to the higher side wall can be increased. The fishing line guiding gap formed between the left and right fishing line guiding members has a width that is the same as or slightly wider than the width of the guide circumferential groove. Specifically, the width of the fishing line guide gap is set to 0.3 to 1.5 mm. If the width of the fishing line guide gap is too narrow, it is difficult for the fishing line to pass through. If the width of the fishing line guiding gap is too wide, the width of the line roller arranged from the fishing line guiding gap to the inside of the left and right fishing line guiding members becomes wide, and it is difficult to achieve the object of the present invention. The width of the fishing line guide gap is preferably set to 3 to 20% of the bottom diameter of the guide circumferential groove. If the width of the fishing line guide gap is too narrow compared to the bottom diameter of the guide circumferential groove, it is difficult to guide the fishing line from the fishing line guide gap to the guide circumferential groove. If the width of the fishing line guide gap is too wide, the width of the line roller must be widened as described above.

The rotor 3 has a first arm portion 5 and a second arm portion 6 that extend forward along the rotation axis, and both arm portions 5 and 6 are arranged so as to face each other. First
The first bail support member 7 is provided on the inner surface of the tip of the arm portion 5.
Is swingably mounted. A line guide member 8 for guiding the fishing line to the spool 4 is attached to the tip of the first bail support member 7. A second bail support member 9 is swingably attached to the inner surface of the tip of the second arm portion 6. A bail 10 is provided between the yarn guide member 8 and the second bail support member 9.

[Structure of Thread Guide Member] Next, the thread guide member 8 will be described in more detail with reference to FIGS. Thread guide member 8
Includes a line roller 15 having a substantially cylindrical shape, a roller support mechanism 16 that is partially housed inside the line roller 15 and rotatably supports the line roller 15 with respect to the first bail support member 7, and the line roller 15. It has a pair of fishing line guide members 50 and 60 arranged on the left and right.

One of the fishing line guide members 50 is integrally formed at the tip of the first bail support member 7 so as to project like a cylinder. The other fishing line guiding member 60 has substantially the same general shape as the fishing line guiding member 50, and is arranged so as to face the fishing line guiding member 50. The roller support mechanism 16 has a fixed shaft 20 protruding to the inner end surface of the fishing line guide member 60, and a rolling bearing 21 mounted on the outer periphery of the fixed shaft 20. The rolling bearing 21 rotatably supports the line roller 15 with respect to the fixed shaft 20.

The fixed shaft 20 of the fishing line guide member 60 is fixed to the fishing line guide member 50 at the tip of the first bail support member 7 by the fixing bolt 2.
Fixed at 2. More specifically, a female screw 20a is formed on the fixed shaft 20, and a fixing bolt 22 penetrating a hole 7a formed at the tip of the fishing line guide member 50 is screwed into the female screw 20a. Thereby, the fixed shaft 20, that is, the fishing line guiding member 60 is fixed to the fishing line guiding member 50, that is, the first bail support member 7. A locking portion (not shown) is formed at the tip of the fixed shaft 20. By locking the locking portion in a groove formed in the fishing line guide member 50, the rotation of the fixed shaft 20 is prohibited. There is. Therefore, it is possible to prevent the engagement between the fixed shaft 20 and the fixed bolt 22 from loosening.

A bearing support member 23 is disposed in the recess 7b formed on the side surface of the fishing line guide member 50. The axial tip of the bearing support member 23 is in contact with one end surface of the inner ring of the rolling bearing 21. The other end surface of the inner ring of the rolling bearing 21 is in contact with the inner end surface of the fishing line guide member 60, and the inner ring of the rolling bearing 21 is positioned. Rolling bearing 21
The bush 26 is provided between the outer ring of the roller and the inner surface of the line roller 15.
Is installed. Fishing line guide member 50 of the bush 26
A flange 26a protruding outward is formed at the end portion on the side, and the flange 26a is arranged so as to be sandwiched between the bearing support member 23 and the line roller 15. This can prevent the bearing support member 23 and the side end surface of the line roller 15 from directly sliding.

The line roller 15 is formed in a substantially cylindrical shape as described above, and has a guide circumferential groove 30 into which the fishing line L is inserted on the outer peripheral surface of the line roller 15. As shown in detail in FIG. 4, the guide circumferential groove 30 has an inverted trapezoidal cross section, and the left and right side walls 34, 34 are inclined upward. The outside of the side walls 34, 34 is an outer peripheral surface parallel to the rotation axis direction, and a part of the outer peripheral surface of the left and right fishing line guiding members 50, 60.
It has entered inside. The bottom surface 32 of the guide circumferential groove 30 is also a flat surface parallel to the rotation axis direction. The upper edges of the side walls 34, 34 are rounded. Guide circumferential groove 3
The width of 0, that is, the distance between the upper edges of the side walls 34, 34 is set to 0.3 to 1.5 mm.

The left and right fishing line guide members 50, 60 have tapered peripheral surfaces 52, 62 which are inclined so that the outer peripheral surfaces on both sides of the guide peripheral groove 30 are inclined toward the center. The inner edges of the tapered peripheral surfaces 52, 62 are arranged substantially above the upper edges of the side walls 34, 34 of the guide circumferential groove 30.
A fishing line guide gap G is formed between the left and right tapered peripheral surfaces 52, 62. The width of the fishing line guide gap G is substantially the same as the width of the guide circumferential groove 30, and is in the range of 0.3 to 1.5 mm.

[Fishing Line Guide Operation] When the rotor 3 is rotated by the handle, the fishing line L is guided by the bail 10 and the line roller 15 and wound up on the spool 4. At this time, the fishing line L is guided to the spool 4 through the guide circumferential groove 30 of the line roller 15. Since the line roller 15 is lightly rotated by the action of the rolling bearing 21 as the fishing line L passes, a large resistance force is not applied to the fishing line L and the fishing line L can pass smoothly. As shown in FIG. 2, even if the amount of the fishing line L wound on the spool 4 changes and the outer diameter changes, the fishing line L is always guided to the spool 4 from a certain point. As a result, the amount of twist generated on the fishing line L becomes stable, and the twist is different between when the fishing line L is paid out and when the fishing line L is wound, and it is less likely that excess twist will remain on the fishing line L.

At the time of the above operation, the fishing line L is pulled by the bail 10.
Is guided along the tapered peripheral surfaces 52, 62 of the fishing line guiding member 60 or the fishing line guiding member 50, enters the fishing line guiding gap G between the fishing line guiding members 50, 60, and is fed into the guide circumferential groove 30. Depending on the direction of the force applied to the fishing line L, the fishing line L that has entered the guide circumferential groove 30
0 side walls 34, 34 to the left and right tapered peripheral surfaces 52, 6
2, the fishing line L is automatically guided toward the guide circumferential groove 30 according to the inclination of the side walls 34, 34 and the inclination of the tapered peripheral surfaces 52, 62. Will be returned.

Since the line roller 15 only needs to have a width a little wider than the width of the fishing line guide gap G, the width of the line roller 15 is small and the weight thereof is also small. Therefore, the rotational mass of the line roller 15 is small, the load applied to the rolling bearing 21 is small, and light rotation is possible. Since the width of the line roller 15 is narrow, the sizes of the left and right fishing line guide members 50 and 60 that house the line roller 15 can be reduced. As a result, the line roller 15 and the fishing line guide member 5
The switching operation of the bail 10 for integrally operating 0, 60, etc. can be performed lightly.

[Another Embodiment] The fishing line guide portion 8 shown in FIGS. 5 and 6 has basically the same structure as the above embodiment. In this embodiment, the left and right side walls 34a and 34b of the line roller 15 have different inclination angles and heights.
The side wall 34a on the side of the bail 10 is relatively low and almost vertical. The opposite side wall 34b has a relatively high slope.

The tapered peripheral surfaces 52, 62 of the fishing line guide members 50, 60 also have different shapes on the left and right sides. The tapered peripheral surface 62 disposed on the side wall 34a on the lower side of the guide circumferential groove 30 has a relatively low inner peripheral edge (a position close to the center of the rotation axis), and the width of the tapered peripheral surface 62 in the horizontal direction. Is relatively long. The tapered peripheral surface 52 disposed on the side wall 34b side of the guide circumferential groove 30 having a high height has a relatively high inner peripheral edge, and the horizontal width of the tapered peripheral surface 62 is relatively short.
Therefore, the fishing line guide gap G is formed on the left and right fishing line guiding members 5
It is not located exactly in the center of the entire width of 0 and 60, but is arranged on the side far from the bale 10.

The line roller 15 arranged inside the fishing line guiding gap G is not directly above the rolling bearing 21 arranged at the center of the entire width of the left and right fishing line guiding members 50, 60, but on the side opposite to the bail 10. It is located slightly offset. A spacer 27 is arranged between the bearing support member 23 and the bush 26, and the bush 26 that supports the line roller 15 is supported by the rolling bearing 21 and the spacer 27. The bush 26 extends to the fishing line guide member 60 side from the rolling bearing 21, has a projection 26 b projecting toward the center of rotation at the tip thereof, and has an outer peripheral surface of the tubular portion 66 of the fishing line guide member 60. Faced with a narrow space between them, foreign matter such as dust is prevented from entering the rolling bearing 21 side from this portion.

In the above embodiment, the fishing line L is the bail 10.
It is smoothly fed from the side to the guide circumferential groove 30 through the fishing line guide gap G along the wide tapered circumferential surface 62. Since the side wall 34b opposite to the guide circumferential groove 30 is high, the fishing line L is prevented from protruding from this side. [Other Embodiments] (a) The shape of the guide circumferential groove 30 is not limited to the illustrated rectangular groove. For example, the bottom surface may be a curved surface such as a cylindrical surface instead of a horizontal surface. The side wall of the guide circumferential groove 30 may be an inclined wall 34, a vertical wall, or a curved surface. The left and right side walls of the guide circumferential groove 30 may have different shapes.

(B) The groove width of the fishing line guide gap G and the groove width of the guide circumferential groove 30 vary depending on the thickness of the fishing line L used. Normally, it is preferable that the gap G and the groove width be slightly wider than the thickness of the fishing line L. When the same line roller 15 is applied to fishing lines L having different thicknesses, a gap G and a groove width wider than those of the thickest fishing line L are adopted. (c) The side wall 34 of the guide circumferential groove 30 may be a curved inclined wall 34 that is inwardly projected or conversely recessed outward, in addition to having a linear inclination. The inclination angle and height of the inclined wall 34 can be appropriately changed other than the illustrated form so that the fishing line L can be guided reliably.

(D) The tapered peripheral surfaces 52 and 62 may be formed as conical surfaces having a linear taper, or may be formed as a drum-shaped or barrel-shaped curved surface bulging on the outer peripheral side. The width and the inclination angle of the tapered peripheral surfaces 52, 62 may be set in consideration of the guide function of the fishing line L, the balance with the guide peripheral groove 30, and the like.

[0035]

The spinning reel according to the present invention is provided with a pair of left and right fishing line guiding members having the above-mentioned tapered peripheral surfaces and a fishing line guiding gap having a width of 0.3 to 1.5 mm formed therebetween. As a result, even if the width of the line roller is narrowed, the guiding and guiding of the fishing line can be performed well. As a result, the line roller becomes smaller and lighter, the rotation operation of the line roller can be performed smoothly, and the line roller housing structure becomes lighter and smaller. Since the fishing line can be smoothly guided by the left and right fishing line guiding members and the line rollers,
It is less likely that the fishing line will be twisted. If the structure related to the line roller is simple and lightweight, the rotor can be easily balanced, and the spinning reel as a whole can be made smaller and lighter.
