Description

  The present invention relates to a fishing reel and a fishing reel spool.

  Generally, a double-bearing type fishing reel is known as a fishing reel used for casting a pseudo bait such as a lure. In this fishing reel, at the time of casting, the spool is switched to a free state by a clutch mechanism, and the spool is rotated at high speed by swinging out the fishing rod to feed out pseudo bait such as lure.

By the way, as a casting method for throwing a lure into a predetermined point, there is known a fishing method (pitching or skipping) in which a light lure is used to swing a small fishing rod and fly the lure to the point. When casting a lure by such a fishing method, if the spool has a large mass, the inertial force of the spool may increase and the flight distance may not increase.
Therefore, in fishing that requires precise casting operation with a light lure as a point, it is required to be configured to reduce the inertial force of the spool.

Conventionally, as a fishing reel configured to reduce the inertial force of a spool, the one described in Patent Document 1 is known.
In this fishing reel, a plurality of through holes are provided in the circumferential direction in the spool bobbin part of the spool and the rising part of the flange part that rises from this bobbin trunk part to reduce the weight of the spool and reduce the inertial force. Yes.

Japanese Patent Laid-Open No. 10-165057

  In Patent Document 1, as described above, a plurality of through holes are provided in the circumferential direction in the rising portion of the flange portion that rises from the bobbin trunk. By the way, the fishing line is tightly wound around the spool body of the spool in a state where a certain tension is applied. For this reason, a large force in the direction of expanding outward in the axial direction by the winding pressure of the fishing line acts on the rising portion of the flange portion that rises from the bobbin trunk. As a result, the rising portion may be deformed, and the outer peripheral portion of the flange portion may come into contact with the inner side surface of the reel body, or the fishing line that contacts the through hole may be cut due to thread rods or scratches. . In addition, there is a risk that the fishing line that comes into contact with the through hole is attached to the fishing line due to the winding pressure of the fishing line or the fishing line is cut.

  In addition, water dropped from the fishing line may enter and adhere to the bearing of the spool shaft through the through hole, resulting in a decrease in bearing performance and a decrease in the flight distance of the lure.

  The present invention solves the above-described problems, has a strength, suitably prevents the fishing line from being damaged, and further can effectively reduce the inertial force, and a spool for the fishing reel. It is an issue to provide.

  The fishing reel of the present invention that solves such problems is a fishing reel provided with a spool that is rotatably supported between the frames of the reel body. The spool includes a bobbin trunk and a flange that rises radially outward from both ends of the bobbin trunk. The flange portion includes a first region that rises radially outward from both ends of the bobbin trunk via an arc-shaped round portion, and a second region that rises radially outward from the first region. . In the second region, a plurality of holes are formed in the circumferential direction.

  In this fishing reel, a hole is formed in a second region which is a region on the radially outer side of the flange portion. That is, since the opening area of the second region can be larger than that of the first region, the spool can be efficiently reduced in weight and the inertia force of the spool can be suitably reduced. Thereby, a lightweight lure can be accurately cast at a point, and fishing operability is improved.

Moreover, since there is no hole in the first region, it is possible to suitably ensure the strength of the rising portion of the flange portion that rises from the bobbin trunk. Therefore, it is possible to prevent deformation at the rising portion of the flange portion due to the winding pressure of the fishing line.
In addition, since there is no hole in the first region, even if the fishing line is strongly pressed against the first region by the winding pressure of the fishing line, the fishing line will not be damaged, and the fishing line will not be hooked. .

  In the fishing reel described above, the hole may be non-circular. With this configuration, it is possible to increase the opening area of the hole as compared with the case where the hole is formed in a circular shape. Thereby, the mass around the outer peripheral part of a flange part is reduced more, and the inertial force of a spool can be reduced more suitably.

  In the fishing reel described above, a flange portion is provided on the outermost part of the flange portion. The hole portion may be formed between an upper end portion of the arc-shaped rounded portion and a lower end portion of the flange portion in the radial direction of the flange portion. By configuring in this way, the strength of the spool can be suitably secured. Therefore, it is possible to reliably prevent deformation from occurring due to the fishing line winding pressure.

In the fishing reel described above, the outer diameter of the flange portion is D1, the outer diameter of the bobbin trunk is D2, the inner diameter of the collar is D3, the diameter of the innermost position of the hole is D4, and the hole When the outermost diameter is D5 and the outermost diameter of the arc-shaped rounded portion is D6, these relationships may be D2 <D6 ≦ D4 <D5 ≦ D3 <D1.
By comprising in this way, a hole part is suitably formed in the area | region of the radial direction outer side of a flange part. Thereby, the mass around the outer peripheral part of a flange part is reduced, and the inertia force of a spool can be reduced suitably. This makes it possible to accurately cast a light lure as a point, and to obtain a fishing reel with improved fishing operability.

  In the fishing reel described above, it is preferable that the hole is formed in a long hole shape in the radial direction as compared with the circumferential direction. By comprising in this way, the mass around the outer peripheral part of a flange part can be reduced suitably, suppressing the cross-sectional area of the hole part in the circumferential direction. Therefore, it is difficult for the fishing line to bite into the hole, and the fishing line can be suitably prevented from being damaged.

  In the fishing reel described above, the hole portion may be inclined from the radially inner side toward the radially outer side with respect to a radial reference line passing through the shaft of the spool. By configuring in this way, the hole can be formed longer by effectively using the narrow space in the radial direction, compared to the case where the hole is provided in parallel to the radial reference line. it can. Therefore, the mass around the outer peripheral portion of the flange portion can be efficiently reduced.

  In the fishing reel described above, the bobbin trunk is fixed to the spool shaft via an annular rib extending in the radial direction. In this case, it is preferable that a plurality of rib holes are formed in the rib portion at intervals in the circumferential direction. With this configuration, the spool can be further reduced in weight.

  The fishing reel spool of the present invention is a spool that is rotatably supported between the frames of the reel body. A bobbin trunk, and a flange that rises radially outward from an end of the bobbin trunk. The flange portion includes a first region and a second region that rises radially outward from the first region. The first region rises radially outward from an end of the bobbin trunk via an arc-shaped rounded portion. The second region rises radially outward from the first region. In the second region, a plurality of holes are formed in the circumferential direction.

  In the fishing reel spool, a hole is formed in a second region that is a region radially outside the flange. That is, since the opening area of the second region can be larger than that of the first region, the spool can be efficiently reduced in weight and the inertia force of the spool can be suitably reduced. Thereby, a lightweight lure can be accurately cast at a point, and fishing operability is improved.

Moreover, since there is no hole in the first region, it is possible to suitably ensure the strength of the rising portion of the flange portion that rises from the bobbin trunk. Therefore, it is possible to prevent deformation at the rising portion of the flange portion due to the winding pressure of the fishing line.
In addition, since there is no hole in the first region, even if the fishing line is strongly pressed against the first region by the winding pressure of the fishing line, the fishing line will not be damaged, and the fishing line will not be hooked. .

  According to the present invention, it is possible to obtain a fishing reel and a fishing reel spool that have strength, suitably prevent a fishing line from being damaged, and can effectively reduce inertial force.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a fishing reel and a spool according to the present invention will be described with reference to the drawings. In the following description, when referring to “front and rear” and “left and right”, the direction shown in FIG. 1 is used as a reference. In each embodiment, the same code | symbol is attached | subjected to the same part and the overlapping description is abbreviate | omitted.

(First embodiment)
As shown in FIG. 1, a fishing reel 100 has a reel body 1 having left and right frames 2 and 3. A spool shaft 4 is rotatably supported between the left and right frames 2 and 3 at the rear portion of the reel body 1. A spool 10 around which a fishing line is wound is integrally fixed to the spool shaft 4.
Both ends of the spool shaft 4 extend to the left and right of the spool 10 as shown in FIGS. Both end portions are supported by the left and right frames 2 and 3 (see FIG. 1) via bearings (not shown).

  As shown in FIG. 1, a handle 5 is rotatably attached to the right side of the reel body 1 via a handle shaft 5a. A known driving force transmission mechanism for transmitting the rotational driving force of the handle 5 from the handle shaft 5 a to the spool shaft 4 is disposed in the right side portion of the reel body 1. Further, a known drag mechanism is disposed between the handle shaft 5a and the driving force transmission mechanism. In the drag mechanism, the transmission of the rotational driving force of the handle 5 and the braking force when the fishing line is pulled out from the spool 10 are adjusted according to how the drag adjusting body 6 is tightened.

  Similarly, a known clutch mechanism for switching the spool shaft 4 between a power transmission state and a power cutoff state is disposed in the right side portion. The clutch mechanism switches from the clutch-on state to the clutch-off state by depressing the operation member 7 behind the spool 10. Further, the clutch mechanism is returned from the clutch OFF state to the clutch ON state by rotating the handle 5.

  A known level wind mechanism 8 that reciprocates and winds the fishing line uniformly around the spool 10 is disposed at the front of the reel body 1. The level wind mechanism 8 includes a fishing line guide body 8a that is driven via a driving force transmission mechanism and reciprocates left and right.

  Next, the spool 10 will be described. As shown in FIGS. 2 (a), 2 (b), and 3 (b), the spool 10 includes a hollow cylindrical bobbin trunk 11, and left and right flanges that rise in the radial direction from the left and right ends of the bobbin trunk 11. 12 and 12. The spool 10 is made of, for example, an aluminum alloy and is integrally formed by cutting. The spool 10 can also be formed of a fiber reinforced resin such as CFRP or GFRP.

  A disc-shaped rib portion 13 is integrally provided at the inner central portion of the bobbin trunk 11 (see FIG. 2B). The rib portion 13 is provided in a state orthogonal to the inner surface of the bobbin trunk portion 11. A plurality of rib holes 13 a are formed in the rib portion 13 in the circumferential direction. A cylindrical spool shaft support portion 14 is integrally provided at the center of the rib portion 13. As shown in FIG. 3B, the spool shaft 4 is inserted into the spool shaft support portion 14 in a non-rotating fitting state.

  The flange portions 12 and 12 serve to prevent the fishing line wound around the bobbin trunk 11 from falling off, and rise from the both ends of the bobbin trunk 11 to the outside in the radial direction. A flange portion 15 that protrudes outward in the axial direction is formed at the radially outermost portion of the flange portions 12, 12.

  As shown in FIGS. 4A and 4B, the flange portions 12 and 12 include two regions, a first region S1 and a second region S2. The first region S1 is a region that rises radially outward from both ends of the bobbin trunk 11 via the arc-shaped rounded portion 16. That is, the first region S <b> 1 includes at least the arc-shaped rounded portion 16 that becomes the rising portion of the flange portion 12. No hole or the like is formed in the first region S1. Therefore, even when a force in the direction of expanding outward in the axial direction is applied to the flange portions 12 and 12 due to the winding pressure of the fishing line, the deformation of the flange portions 12 and 12 is preferably prevented.

  The second region S2 is a region that rises radially outward from the first region S1, and does not include the rising portion of the flange portion 12 (the arc-shaped round portion 16). The second region S2 includes the flange 15.

  In the second region S2, a plurality of hole portions 20 penetrating the flange portion 12 in the axial direction are arranged in parallel at predetermined intervals in the circumferential direction (see FIGS. 2 and 3). As shown in FIG. 4B, the hole 20 has a non-circular shape when viewed from the axial direction, and is formed in a rectangular long hole shape that is longer in the radial direction than in the circumferential direction. The hole 20 extends from the radially inner side to the radially outer side in the fishing line winding direction (arrow direction in the drawing) of the spool 10 with respect to a radial reference line K1 passing through the axis O1 (center of the spool shaft 4) of the spool 10. It is tilted by θ degrees. The inclination angle θ of the hole 20 with respect to the reference line K1 is preferably set in a range of 30 to 60 degrees, for example. By inclining, the cross-sectional area of the hole 20 can be increased while reducing the number of the holes 20, so that the moment of inertia can be reduced while suppressing a decrease in strength.

Here, as shown in FIG. 4A, the outer diameter of the flange portion 12 is D1, the outer diameter of the bobbin trunk portion 11 is D2, the inner diameter of the flange portion 15 (the lower end portion of the flange portion 15) is D3, and the hole portion. When the diameter of the innermost position of D20 is D4, the diameter of the outermost position of the hole 20 is D5, and the outermost diameter of the rounded portion 16 is D6, these relationships are expressed by the following formula (1). Is set to have.

D2 <D6 ≦ D4 <D5 ≦ D3 <D1 (1)

  That is, in the second region S2, the range in which the hole 20 is formed is not less than the outermost diameter D6 of the rounded portion 16 (the upper end portion of the arc-shaped rounded portion 16) and the inner diameter D3 of the flanged portion 15 (of the flanged portion 15). The lower end of the arcuate rounded portion of the inner diameter) is in the following range. In the present embodiment, as shown in FIG. 4A, the position slightly outside the outermost diameter D <b> 6 of the rounded portion 16 is slightly inside in the radial direction from the inner diameter D <b> 3 of the flange portion 15. The hole 20 is formed by using a region partitioned by position. That is, the hole 20 is disposed with a slight space inside and outside the hole 20 in the second region S2. Thereby, the intensity | strength around the hole 20 is improving compared with the case where the hole 20 is formed without forming some space. The formation range of the hole 20 is appropriately set within the range of the second region S2 in consideration of the inertial force and strength of the spool 10 in consideration of the size, form, material, and the like of the spool 10.

  Here, the outer diameter D1 of the flange portion 12 is preferably set in a range of 28 to 42 mm. The outer diameter D2 of the bobbin trunk 11 is preferably set in the range of 17 to 38 mm. Moreover, it is preferable that the radius R of the arc-shaped rounded portion 16 is set in a range of 1 to 5 mm. By setting in the above range, it is possible to obtain the spool 10 that can be efficiently reduced in weight and that can suitably reduce the inertial force.

  In the present embodiment described above, the hole 20 is formed in the second region S <b> 2 that is a radially outer region of the flange portion 12. That is, since the opening area of the second region S2 formed radially outward than the first region S1 can be increased, the spool 10 can be efficiently reduced in weight, and the inertial force of the spool 10 can be suitably increased. Can be reduced. As a result, the free rotation performance of the spool 10 can be remarkably improved, so that it is possible to perform casting that accurately inputs a light lure to a point, and the fishing operability is improved. A fishing reel 100 is obtained.

Moreover, since the hole part 20 does not exist in 1st area | region S1, the intensity | strength of the standing part (Ru part 16) of the flange part 12 rising from the bobbin trunk part 11 can be ensured suitably. Therefore, it is possible to prevent deformation of the rounded portion 16 due to the winding pressure of the fishing line.
Further, since the hole portion 20 does not exist in the first region S1, even if the fishing line is strongly pressed against the first region S1 by the winding pressure of the fishing line, the fishing line is not damaged, and the fishing line is attached to the fishing line. There is nothing.

  Moreover, since the hole part 20 is non-circular, it becomes possible to take the opening area of the hole part 20 large compared with the case where it forms in circular shape. Thereby, the mass around the outer peripheral part of the flange part 12 is reduced more, and the inertial force of the spool 10 can be reduced more suitably.

  Further, since the hole 20 is formed in a region defined by the outermost diameter D6 of the arc-shaped rounded portion 16 and the inner diameter D3 of the flange portion 15 in the radial direction of the flange portion 12, the strength of the spool 10 is increased. It can be suitably secured. Therefore, it is possible to reliably prevent deformation from occurring due to the fishing line winding pressure.

  Further, since the spool 10 has a relationship of D2 <D6 ≦ D4 <D5 ≦ D3 <D1, the hole portion 20 is preferably formed in the radially outer region (second region S2) of the flange portion 12. The Thereby, the mass around the outer peripheral part of the flange part 12 is reduced, and the inertial force of the spool 10 can be suitably reduced. This makes it possible to accurately cast a light lure as a point, and to obtain a fishing reel with improved fishing operability.

  Moreover, since the hole part 20 is formed in the shape of a long hole in the radial direction compared with the circumferential direction, the mass around the outer peripheral part of the flange part 12 is suitably reduced while suppressing the cross-sectional area of the hole part 20 in the circumferential direction. can do. Therefore, it is difficult for the fishing line to bite into the hole 20, and the fishing line can be suitably prevented from being damaged.

  Further, since the hole portion 20 is inclined with respect to the reference line K1 of the spool 10, compared to the case where the hole portion 20 is provided in parallel to the reference line K1, a narrow radial space is provided. It can be formed long by making effective use. Therefore, the mass around the outer peripheral portion of the flange portion 12 can be efficiently reduced.

  Moreover, since the rib part 13 is formed with a plurality of rib holes 13a in the circumferential direction, the weight of the spool 10 can be further reduced.

(Second Embodiment)
Next, the spool applied to the fishing reel of the second embodiment will be described with reference to FIGS. This embodiment is different from the first embodiment in that a short hole portion 20A is provided in the radial direction in order to lighten only the outer portion of the flange portion 12.
As in the first embodiment, a plurality of holes 20A are arranged in parallel at predetermined intervals in the circumferential direction. As shown in FIGS. 5 and 6, the hole 20 </ b> A has a non-circular shape in a side view and is formed in a quadrangular hole shape that is somewhat longer in the radial direction than in the circumferential direction. That is, the hole 20A is shorter in the radial direction than the hole 20 described in the first embodiment.
Further, as shown in FIGS. 6A and 6C, the hole portion 20A has a radial outer side from a radial inner side with respect to a radial reference line K1 passing through the axis O1 of the spool 10 (center of the spool shaft 4). Inclined towards.

  In this embodiment, the same effect as the first embodiment can be obtained. In addition, since the hole portion 20A is formed shorter in the radial direction than the hole portion 20 of the first embodiment, the spool 10 is made efficient while ensuring the strength on the side close to the round portion 16 in the second region S2. It can be lightened well. Thereby, the inertia force of the spool 10 can be reduced suitably. Therefore, the fishing reel 100 can be obtained which can be accurately cast with the light lure as a point and the fishing operability is improved.

(Third embodiment)
A spool applied to the fishing reel of the third embodiment will be described with reference to FIGS. This embodiment is different from the first and second embodiments in that the right and left flange portions 12 and 12 are different in the inclination direction of the hole 20B.

  As shown in FIGS. 7A, 7B, and 8C, the hole 20B in the right flange portion 12 has a direction in which the spool 10 is fed out of the fishing line in a different direction from that of the embodiment (FIG. 7A). It is inclined in the direction of the middle arrow X1) from the radially inner side to the radially outer side. On the other hand, as shown in FIGS. 7A and 7B and FIG. 8A, the hole 20B in the left flange portion 12 has a fishing line winding direction (see FIG. ) In the middle arrow X2 direction) from the radially inner side toward the radially outer side.

  In both the left and right flange portions 12 and 12, the hole portion 20B has a steep inclination angle as compared with that of the above-described embodiment (see FIGS. 8A and 8C). Thereby, the hole 20B can be formed longer by effectively using the narrow space in the radial direction. Therefore, the mass around the outer peripheral portion of the flange portion can be more efficiently reduced.

  According to the present embodiment, the right and left flange portions 12 and 12 have different inclination directions of the hole portion 20B. Therefore, when the hole 20B is formed by cutting or the like, the hole 20B may be formed in the same inclination direction without changing the inclination direction for each of the left and right flange portions 12 and 12, and productivity is improved.

  Moreover, the hole 20B has a steep inclination angle compared to that of the above embodiment. Thereby, the hole 20B can be formed longer by effectively using the narrow space in the radial direction. Therefore, the mass around the outer peripheral portion of the flange portion can be more efficiently reduced.

As mentioned above, although embodiment of this invention was described, this invention is not limited to above-described embodiment, It can change variously.
For example, in each of the above-described embodiments, the hole 20 (20A, 20B) is provided in both the left and right flanges 12 and 12, but the present invention is not limited to this, and it may be provided only in either the left or right.

  In each of the above embodiments, the shape of the hole 20 (20A, 20B) has been described as a rectangular shape. However, the shape is not limited to this, and a rectangular shape, an elliptical shape, a triangular shape, a polygonal shape, a circular shape, etc. Various shapes can be employed.

  Moreover, the hole 20 (20A, 20B) may be formed in a long circular arc shape in the circumferential direction, or may be a hole that does not penetrate the flange 12.

  Further, as shown in FIGS. 9A and 9B, a plurality of body hole portions 11a may be formed in the bobbin body 11 to reduce the weight of the spool 10.
