Description

  The present invention relates to a fishing spinning reel characterized by a rotor portion that rotates in conjunction with a rotation operation of a handle.

  Usually, a fishing spinning reel includes a rotor provided with a fishing line guide and a spool around which a fishing line is wound, and simultaneously rotates the rotor by rotating a handle and simultaneously reciprocates the spool. It has a configuration. The rotor is formed with a pair of arm portions facing each other on both sides of the rear portion of the cylindrical main body portion, and the fishing line is connected to the spool that moves back and forth via the fishing line guide portion provided on one arm portion. Is to be wound.

  In the fishing spinning reel having the above-described configuration, when the handle is actually caught and the handle is wound, a large load is applied to the fishing line, and the arm portion of the rotor is deformed radially inward during winding. Therefore, there is a possibility that the outer periphery of the spool may hit. In addition, there is a problem that when dragging out, pulsation occurs due to deformation of the arm portion and smooth fishing line cannot be fed out.

  Therefore, for example, Patent Document 1 discloses a fishing spinning in which a belt-shaped reinforcing member is bridged in a circular arc shape on the fishing line discharge position side at a predetermined distance from the outer periphery of the rotor on the distal end side of the pair of arm portions. A reel is disclosed.

Japanese Patent No. 2894422

However, in the fishing spinning reel disclosed in Patent Document 1, the reinforcing member is disposed between the tip ends of the pair of arm portions at a predetermined distance from the outer periphery of the cylindrical portion of the rotor so as to surround a part of the outer periphery of the spool. Since the structure is constructed in the shape of an arc, the weight is biased toward the front side of the rotor, and therefore it is difficult to achieve an efficient weight balance. Further, since the reinforcing member is arranged on the outer peripheral side of the spool for winding the fishing line, the fishing line is easily entangled with the reinforcing member, and the reinforcing member is in the way and it is difficult to lock the fishing line to the line holder.
Further, in the fishing spinning reel disclosed in Patent Document 1, the arm portion has a thick-walled base portion due to the reinforcing member being erected on the distal end side. However, it is inferior in fishing operability.
Further, it is desirable that the reinforcing member can be efficiently reduced in weight while sufficiently considering stress distribution and rigidity so as not to hinder the reduction in size and weight of the reel.

  The present invention has been made paying attention to the above circumstances, and the purpose thereof is to sufficiently reinforce the arm portion by the reinforcing member without hindering the fishing line operation, and to efficiently reduce the weight of the reinforcing member. An object of the present invention is to provide a fishing spinning reel with an excellent weight balance that can reduce the weight of the rotor as much as possible.

  In order to solve the above-described problem, the invention described in claim 1 includes a reel body, a rotor rotatably provided on the reel body, and a spool around which a fishing line is wound, and the rotor includes a body portion.

  According to the first aspect of the present invention, the reinforcing member is bridged between the side portion of the one arm portion and the side portion of the other arm portion. Even when a load is applied, stress can be distributed by the reinforcing member, and the arm portion can be effectively reinforced and prevented from being deformed. In addition, the reinforcing member is bridged so as to protrude away from the arm portion as it moves to the base side of the arm portion, and becomes convex toward the reel body side, so that the base portion of the arm portion becomes thicker This makes it possible to reduce the weight of the rotor as much as possible (and therefore excel in fishing operability), and the weight is not biased toward the front side of the rotor, so that an efficient weight balance can be achieved. Can do. Further, since the reinforcing member is not disposed on the outer peripheral side of the spool for winding the fishing line, the fishing line operation is not hindered (the fishing line is not entangled with the reinforcing member). Moreover, stress concentration can be avoided particularly by the formation form of such a reinforcing member. Furthermore, according to the above configuration, a part of the material forming the reinforcing member (second material) is made different from the material forming the main body of the rotor (first material). (A desired performance improvement can be facilitated by increasing the degree of freedom of material selection).

  In the above configuration, the “base portion of the arm portion” is a connection portion between the main body of the rotor and the arm portion, and is an end portion located on the reel main body side of the arm portion.

Further, since the rigidity is improved, the reinforcement member can be prevented from being deformed, and thus the arm portion can be prevented from being deformed radially inward, so that the situation in which the inner side of the arm portion hits the outer periphery of the spool can be avoided. The position will be difficult to shift, and uneven winding will not be possible.

Further, there is no restriction on the surface finish in appearance (for example, the same surface treatment as that of the rotor main body can be applied to the reinforcing member). For example, by making the material of the outer peripheral area of the reinforcing member the same as the material of the rotor main body, the reinforcing member can be welded to the main body, and electrolytic corrosion can be prevented.

In particular, as shown in FIG. 1, the reel body 1 of the fishing spinning reel of the present embodiment includes a handle 2 that is rotated, a rotor 3 that is rotated by the rotation of the handle 2, A spool 5 is provided that is moved back and forth in synchronization with the rotational drive and on which the fishing line is wound.

  In the reel body 1, a handle shaft 2a on which a handle 2 is mounted is rotatably supported via a bearing. The handle shaft 2a transmits a rotation operation of the handle 2 to the rotor 3 and also has a spool. 5 is engaged.

  The power transmission mechanism 6 includes a drive gear (drive gear) 7 that is mounted on the handle shaft 2a so as to be integrally rotatable, and a rotary shaft cylinder 8 that extends in a direction orthogonal to the handle shaft 2a. A pinion 8 a that meshes with the drive gear 7 is formed on the base end side of the rotary shaft cylinder 8, and a rotor nut is screwed to the tip portion so that the rotor 3 is connected to the rotary shaft cylinder 8. Attached.

  In addition, a spool shaft 5 a that holds the spool 5 around which the fishing line is wound is inserted in the rotary shaft cylinder 8. A known oscillating mechanism is connected to the spool shaft 5a, and when the handle shaft 2a is rotated by a rotation operation of the handle 2, the spool shaft 5a is driven back and forth in the axial direction.

  According to the above configuration, by rotating the handle 2, the rotor 3 is rotationally driven via the drive gear 7 and the pinion 8a (rotary shaft cylinder 8) meshed therewith, and the spool 5 is oscillating. It is driven back and forth through the mechanism. In this case, as will be described in detail below, the rotor 3 is provided with a fishing line guide portion 3d, and the fishing line winding body portion 5b of the spool 5 is provided with a fishing line guide portion 3d provided on the rotor 3. The fishing line is wound evenly.

  The rotor 3 includes a main body portion 3a formed in a substantially cylindrical shape, and a pair of arm portions 3b are formed on both sides thereof at an interval of about 180 °. As shown in FIG. 2, each arm portion 3b is integrally formed with the main body portion 3a together with a connecting portion 3b 'protruding radially outward from the rear portion (reel main body 1 side) of the main body portion 3a. It is extended. As a result, a gap is formed between the main body portion 3a and each arm portion 3b, and the skirt portion 5c of the spool 5 is positioned in this portion as shown in FIG.

  As is well known, a support member 3c that supports the bail 3e is supported at the tips of the pair of arm portions 3b so as to be reversible between a fishing line winding position and a fishing line discharge position about a support shaft 3c '. A fishing line guide portion (line roller) 3d for guiding the fishing line wound around the spool 5 is provided at the tip of one support member 3c. A bale 3e is provided between the support members 3c. When the support member 3c is reversed from the fishing line discharge position to the fishing line winding position, the fishing line is picked up and guided to the fishing line guide portion 3d. In the figure, reference numeral 3f denotes a cover member that covers the surface of the arm portion 3b.

  A reversal holding mechanism (not shown) is provided in one of the pair of arm portions 3b to reverse and hold the support member 3c between the fishing line winding position and the fishing line discharge position. . A reinforcing member 10 is provided on the pair of arm portions 3b.

Hereinafter, the configuration of the reinforcing member 10 of the present embodiment will be described in detail.
As shown in FIGS. 1 to 7, the reinforcing member 10 extends from the side portions of the pair of arm portions 3 b toward the rear portion (reel main body 1 side) of the main body portion 3 a of the rotor 3, and the main body portion 3 a. Not connected to. In this case, as shown in FIG. 3, the reinforcing members 10 are preferably provided on both side portions of the pair of arm portions 3b, and the reinforcing members 10 provided on both side portions are preferably substantially the same shape. The arm portion 3b extends from the front portion (portion where the support member 3c is provided) on the side portion of the arm portion 3b toward the base portion (portion on the connecting portion 3b ′ side), and gradually shifts to the base portion side. The shape is separated from 3b. That is, it is formed in a substantially C-shaped shape in a side view (refer to FIG. 3) in a direction in which both arm portions 3b face each other, whereby the reinforcing member 10 is provided on both sides of the base portion of the arm portion 3b. A gap S exists between the two. Note that the gap S gradually expands in a side view.

  Further, in the present embodiment, the reinforcing member 10 has a structure that is bridged between the pair of arm portions 3b, is continuously formed without being cut between the pair of arm portions 3b, and protrudes toward the reel unit side. It has become a shape.

  In the present embodiment, the reinforcing member 10 has a shape that is curved toward the reel body 1 between the pair of arm portions 3b, and as shown in FIG. With respect to the region 99, when the spool 5 reciprocates and moves to the reel body side, it is positioned closer to the reel body than the rear edge (line indicated by R) of the skirt portion 5c of the spool. Yes. More specifically, as shown by the line R, when the spool 5 moves to the reel main body side, a part of both sides of the rear end of the skirt 5c overlaps, and the spool 5 reciprocates. However, the back-and-forth movement state is not obstructed by the reinforcing member 10 and can be easily recognized.

  In the present embodiment, the main body 3a of the rotor 3 is formed of the first material, and at least a part of the reinforcing member 10 (in the present embodiment, a substantially whole portion shaded in FIGS. 2 to 6). ... Of course, all or part of the reinforcing member 1 may be formed by a second material different from the first material (a part of the reinforcing member 10 is formed by the second material). In other words, the other parts of the reinforcing member 10 are formed of the same first material as that of the rotor body 3a, for example). As described above, by making a part of the material forming the reinforcing member 10 (second material) different from the material forming the main body portion 3a of the rotor 3 (first material), further weight reduction and strength improvement are achieved. (A desired performance improvement can be facilitated by increasing the degree of freedom of material selection). For example, in order to efficiently reduce the weight of the reinforcing member 10 while increasing the rigidity by the reinforcing member 10, as shown in FIG. 6, the center point M of the fishing line guide portion 3d (the fishing line guide portion 3d as in the present embodiment). In the case of a roller configuration, the center of the roller 3 is the most distant from the center of the roller width direction and the center of the roller circle (axial center) along the axial direction of the rotor 3 (from the center M of the fishing line guide portion 3d to the axis of the rotor 3). The portion L of the reinforcing member 10 having the largest distance L (see FIG. 3) along the direction (therefore, the convex apex portion of the arc of the reinforcing member 10, that is, the lowermost end portion in the region of the longitudinal intermediate portion 99) In the configuration in which the reinforcing member 10 is not connected to the main body portion 3a of the rotor as in the present embodiment, the stress is substantially maximum at this portion), and the area is the largest in a cross section obtained by cutting the reinforcing member 10 at an arbitrary angle. Small cross section (elliptical) ) Is A, G is the centroid of the cross section A, P is the plane including the cross section A, and K is the foot of the perpendicular line from the center point M of the fishing line guide portion 3d to the plane P. And the secondary moment of inertia I (m) of the cross section A with respect to the linear axis m passing through and the secondary moment of inertia I (of the cross section A with respect to the linear axis n in the plane P passing through the centroid G and perpendicular to the linear axis m. n) and the reinforcing member 10 is preferably formed so that the relationship of I (m) <I (n) is established, and by appropriately selecting the first material and the second material, Further, the effect can be increased. In the realization of I (m) <I (n), the shape of the cross section A is designed so that the strong axis direction (the axis where the secondary moment of inertia is the maximum in structural mechanics) coincides with the n axis direction. The Thus, the linear axis n is preferably substantially coincident (± 30 °) with the strong axis of the cross section A, and is particularly preferably perfectly coincident. In this configuration, as shown in FIG. 7, it is preferable that the point K coincides with the extending direction of the reinforcing members 10 on both sides of the rotor 3.

  In selecting the first and second materials, the Young's modulus of the second material is made larger than the Young's modulus of the first material, and the tensile strength of the second material is set to the tensile strength of the first material. The vibration damping factor of the second material is larger than the vibration damping factor of the first material, or the elongation of the second material is larger than the elongation of the first material. Be considered.

  In such material selection, the inventors of the present application particularly combined the following three materials: (1) First material: nylon containing a glass short fiber with a weight content of 55% (hereinafter, glass 55). % Material) / second material: aluminum alloy material JIS standard A7075 (hereinafter simply referred to as A7075), (2) first material: glass 55% nylon / second material: weight content 40 % Containing short carbon fibers (hereinafter referred to as CFRP 40% nylon), (3) First material: JIS standard ADC12 material (hereinafter simply referred to as ADC12) / second material, which is an aluminum alloy for die casting : Attention was paid to Ti-6Al-4V, which is a titanium alloy. Here, the Young's modulus, tensile strength, vibration damping rate, and elongation of glass 55% nylon are 18 GPa, 216 MPa, 0.1, and 2%, respectively. The Young's modulus, tensile strength, vibration damping rate, and elongation of A7075 are each 72 GPa, 573 MPa, 0.002, and 11%. CFRP 40% nylon has Young's modulus, tensile strength, vibration damping rate, and elongation of 38 GPa, 320 MPa, 0.08, and 3.3%, respectively. Rate, tensile strength, vibration damping rate, and elongation are 70 GPa, 228 MPa, 0.002, and 2.5%, respectively, and the Young's modulus, tensile strength, and vibration of Ti-6Al-4V (alloy of titanium, aluminum, and vanadium). The damping rate and elongation are 106 GPa, 980 MPa, 0.001, and 14%, respectively. Each of these combinations is a combination that satisfies the requirement that the second material is larger than the first material in terms of Young's modulus, tensile strength, vibration damping rate, and elongation. In particular, in the structure of this embodiment, The combination of (1) is a good choice for Young's modulus, tensile strength, and elongation. In particular, regarding the elongation, the selection of (1) and (3) is more preferable than the selection of (2).

  In the present embodiment, the reinforcing member 10 is connected to the side portion of the arm 3b by, for example, adhesion, screwing, welding, brazing, caulking, or the like.

  As described above, according to the fishing spinning reel of the present embodiment, the reinforcing member 10 is bridged between the side portion of the one arm portion 3b and the side portion of the other arm portion 3b. Even if a large load acts on the arm portion 3b due to the tension of the fishing line, the stress can be dispersed through the reinforcing member 10 and deformation of the arm portion 3b can be prevented. In addition, since the reinforcing member 10 can be provided with a gap such as the gap S appropriately without increasing the thickness of the base of the arm 3b, the strength of the arm can be maintained. It is possible to reduce the weight as much as possible (thus, excellent fishing operability).

  In particular, in the present embodiment, the reinforcing member 10 is bridged between the arm portions 3b so as to be convex (curved) toward the reel body 1 side. When a load is applied, the stress can be effectively dispersed to avoid stress concentration, and the arm portion 3b can be reinforced more effectively. Further, since the reinforcing members 10 are provided on both side portions of the arm portion 3b, it is possible to improve the reinforcement of the arm portion 3b more effectively and to improve the rotation balance of the rotor 3. Further, since the weight does not deviate toward the front side of the rotor 3, the weight balance can be achieved efficiently. Further, since the reinforcing member 10 is not disposed on the outer peripheral side of the spool 5, the fishing line does not get entangled with the reinforcing member 10, and the reinforcing member 10 becomes in the way and it is difficult to lock the fishing line to the line holder. There is nothing.

  Further, the two reinforcing members 10 are separated from each other as they move to the base side of the arm portion 3b with respect to both side portions of the arm portion 3b, and are formed in a substantially C shape in a side view. Becomes a so-called tapered shape, and even if the fishing line becomes entangled with the arm portion due to the thread dandruff or the thread twisting at the time of release, it can be easily pulled forward and the trouble can be solved. Further, by causing the curved reinforcing member 10 to protrude further downward than the lower edge of the skirt of the spool 5, the shape of the rotor portion changes and the appearance can be improved.

  Furthermore, according to the present embodiment, a part of the material forming the reinforcing member 10 (second material) is made different from the material (first material) forming the main body portion 3a of the rotor 3, so that the weight is further reduced. Various performance improvements such as improvement of strength and strength can be achieved. That is, it is possible to easily satisfy the requirements regarding Young's modulus, tensile strength, vibration damping rate, elongation, and the like. In particular, as described above, the effect becomes larger under the condition that I (m) <I (n) is satisfied. In particular, when selecting the material, if the Young's modulus of the second material is larger than the Young's modulus of the first material, the rigidity of the reinforcing member 10, and thus the rigidity of the rotor 3 can be increased efficiently. Further, since the rigidity is improved, the reinforcement member 10 can be prevented from being deformed, and thus the arm portion 3b can be prevented from being deformed radially inward, so that the situation where the inner side of the arm portion 3b hits the outer periphery of the spool 5 is avoided. The position of the fishing line guide portion 3d is difficult to shift, and uneven winding is not possible. Further, when the tensile strength of the second material is made larger than the tensile strength of the first material, the strength of the reinforcing member 10, and thus the strength of the rotor 3 can be increased efficiently. Further, it is possible to realize the reinforcing member 10 that is not easily damaged even if the weight is reduced. Therefore, it becomes difficult to break even if a large fish is applied. Furthermore, if the vibration attenuation rate of the second material is larger than that of the first material, the vibration of the arm portion 3b (especially easily generated during reel rotation) can be efficiently suppressed, and the reel can be gripped. The hand feels better. In addition, since unnecessary vibration is eliminated, the fish hit at the time of winding the thread becomes clear. Further, if the elongation of the second material is larger than the elongation of the first material, even when a large load is applied by hitting the reinforcing member 10 against an obstacle, the (eg, sharp) cross section is difficult to be exposed. High safety. In particular, since centrifugal force works during the rotation of the rotor 3, it is extremely dangerous that splintered pieces (for example, sharp) of the damaged reinforcing member 10 are scattered, and in that sense, safety is high.
