Description

  The present invention relates to a fishing reel provided with a braking force adjusting device capable of adjusting a braking force acting on a spool rotatably provided on a reel body.

  In general, a fishing reel is a braking device (drag device) that prevents the fishing line from being cut or the fish from being cut by allowing the spool to slip and rotate when excessive tension is applied to the fishing line. It has.

  However, since the winding diameter of the fishing line wound around the spool changes due to repeated feeding and winding of the fishing line during actual fishing, the tension actually acting on the fishing line due to the moment of the winding diameter position from the spool shaft Not constant. In other words, the tension of the fishing line is weak when the bobbin diameter is large and becomes strong when the bobbin diameter is small, so even if a predetermined braking force is applied to the spool by a normal braking device, The tension is not constant in response to the change in the bobbin diameter, and troubles such as cutting of the fishing line and cutting of the mouth of the fish cannot be reliably prevented.

Therefore, in Patent Document 1, at least the front flange of the spool is formed of a flexible member such as a synthetic resin, a braking member is disposed in front of the front flange, and the bending change of the front flange in accordance with the amount of winding of the fishing line. A technique for correcting a change in tension due to a change in bobbin diameter by using the above is disclosed. According to such a technique, when the spool winding amount of the spool is large, the front flange is greatly bent, so that the braking force of the spool can be increased, and as the spool winding amount of the spool decreases, Since the amount of bending of the front flange is reduced and the braking force of the spool is reduced, it is possible to correct (adjust) the change in tension acting on the fishing line in accordance with the amount of fishing line feed.

  According to the above-described known technology, it is necessary to form the flange of the spool with a flexible material, shape, or size, and there are many restrictions on the material, size, etc., and the degree of freedom in spool design is small. There is.

  Further, since the flange portion is bent in the front-rear direction, the fishing line guide position of the fishing line winding body of the spool relative to the fishing line guide provided on the rotor, that is, the spool stroke is changed, and the winding state is adversely affected. End up.

  The present invention has been made based on the above-described problems, and can maintain a stable thread winding state without being restricted by materials, dimensions, etc., and provides a spool braking force according to the thread winding diameter. An object of the present invention is to provide a fishing reel provided with a braking force adjusting device.

  In order to achieve the above-described object, a fishing reel according to the present invention is rotatably supported on a support shaft of a reel body and includes a spool having a flange portion that regulates a wound fishing line, and the spool. And a braking force adjusting portion that adjusts a braking force that acts on the spool when the fishing line is fed out according to a winding diameter of the fishing line, and the braking force adjusting portion projects from the flange portion along the radial direction. And a pressure detecting member that is pressed in the axial direction by a wound fishing line, and a braking member that applies a braking force to the spool by the pressure detecting member. .

  In the fishing reel having the above-described configuration, the protruding portion of the pressure detection member receives a pressure corresponding to the winding diameter of the fishing line wound around the spool. That is, when the winding diameter is large, a large pressure (fishing winding pressure) acts on the pressure detection member, and when the winding diameter is small, a small pressure acts on the pressure detection member. Since the pressure acting on the pressure detection member applies a braking force to the spool via the braking member, when the winding diameter is large, the braking force acting on the spool becomes large, and as the winding diameter decreases. Thus, the braking force acting on the spool is reduced. Therefore, even if the tension acting on the fishing line changes due to a change in the winding diameter of the fishing line, the change in tension is corrected by the pressure detection member, so troubles such as cutting of the fishing line or cutting of the fish when the fishing line is fed out. Is prevented. Further, since the pressure detecting member is provided, it is not necessary to bend the flange portion, and a normal spool structure can be obtained, so that the spool stroke is stabilized and the thread winding state is not adversely affected.

  According to the present invention, fishing with a braking force adjusting device capable of maintaining a stable spool winding state without being restricted by material, dimensions, etc., and applying a spool braking force according to the spool diameter. A reel is obtained.

  FIG. 1 to FIG. 5 are views showing an embodiment of the present invention, FIG. 1 is a view showing the entire configuration of a spinning reel which is a fishing reel, and FIG. 2 is an exploded perspective view of the main part of the spool. 3 is a cross-sectional view taken along the line AA in FIG. 1, FIG. 4 is a plan view of the pressure detection member, and FIG. 5 is a cross-sectional view taken along the line BB in FIG.

  The reel body 1 of the spinning reel is integrally formed with a reel leg 1a attached to a fishing rod. The rotor 2 is rotatably supported in front of the reel leg 1a and can be moved back and forth in synchronization with the rotational movement of the rotor 2. And a spool 3 around which the fishing line is wound and held.

  In the reel body 1, a known take-up drive mechanism 5 for rotating and driving the above-described rotor 2 and reciprocating the spool 3 is disposed. The take-up drive mechanism 5 includes a reel body. 1 is driven by a winding operation of the handle 6 supported so as to be rotatable relative to 1. That is, a drive gear (face gear) 7 constituting a part of the winding drive mechanism 5 is mounted on the rotational drive shaft 6 a of the handle 6, and the rotor 2 has a pinion 8 meshing with the drive gear 7. The spool 3 is driven to reciprocate back and forth via a known gear oscillation mechanism 10.

  The oscillating mechanism 10 includes a gear 11 that rotates in conjunction with the drive gear 7, engages with the rear end of the support shaft 12 that is supported in the reel body 1, and the support shaft rotates as the drive gear 7 rotates. 12 is moved back and forth. In this case, the support shaft 12 is inserted through the pinion 8, and the spool 3 is rotatably supported by a known braking device (drag device) 15 at a tip region thereof.

  The spool 3 includes a fishing line winding body portion 3a around which a fishing line is wound, a front flange portion 3b that is formed on both sides in the axial direction and restricts the fishing line that is wound, and a rear flange portion 3c. The rear flange portion 3 c hangs down toward the rear side in the axial direction and is integrated with a skirt portion 3 d that covers the rotor 2. The spool 3 is integrally formed of a material that the flange portions 3b and 3c are not bent and deformed, for example, aluminum, an aluminum alloy, a hard resin, or the like.

  According to the spinning reel having the above-described configuration, when the handle 6 is rotated, the rotor 2 is rotationally driven via the winding drive mechanism 5 and the spool 3 is reciprocated back and forth via the oscillating mechanism 10. The fishing line is evenly wound around the fishing line winding body 3a of the spool 3 through a fishing line guide (not shown) provided at the tip of the rotor arm 2a formed integrally with the rotor 2.

  The braking device 15 is a generally known front drag device, and is a front knob (drag knob) 16 provided at the front end of the support shaft 12, and is pressed by the front knob 16 and the spool 3. And a braking portion 17 that generates a predetermined frictional force. In other words, the spool 3 is supported so as to be rotatable with respect to the support shaft 12. However, by rotating the front knob 16, the spool 3 is supported so as to be rotatable with a predetermined braking force. It is in the state. For this reason, when the fishing line is to be fed out, such as when a fish is caught, the spool can be rotated with a predetermined braking force, and troubles such as thread breakage are prevented.

  The flange portion of the spool 3 is provided with a braking force adjusting portion (braking force adjusting device) 20 for adjusting the braking force acting on the spool as described above. The braking force adjusting unit 20 detects the fishing line winding pressure corresponding to the winding diameter of the fishing line wound around the fishing line winding body 3a, and corrects the braking force applied to the spool 3 according to the pressure. It is provided to be displaceable with respect to the flange portion in a fixed state.

  The braking force adjusting unit 20 in the present embodiment is installed on the rear flange portion 3c, and a pressure detection member 21 that detects a pressing force according to the winding diameter of the fishing line, and the pressure detection member 21 against the spool 3. And a braking member 23 for applying a braking force.

  The pressure detection member 21 is formed in an annular shape having substantially the same diameter as the rear flange portion 3c, and is accommodated in the skirt portion 3d. The pressure detecting member 21 has a protruding portion 21a (pressure detecting portion) that comes into contact with the fishing line wound around the fishing line winding body, and this protruding portion 21a has a predetermined interval (in the present embodiment, approximately). Projectingly formed on the surface 21b of the pressure detection member 21 along the radial direction at four positions at 90 ° intervals.

  The fishing line regulating surface 3e which is the surface of the rear flange portion 3c is formed with four openings 3f at substantially 90 ° intervals so that the protruding portions 21a can protrude. The portion 21a is held in a state of protruding from the fishing line regulating surface 3e.

  The braking member 23 includes an annular lining material 23a that is in surface contact with the back surface side of the pressure detection member 21, and a washer 23b that is in surface contact with the lining material 23a. The washer 23b is formed with an opening 23c having a non-circular cross section at the center, and is fixed to the support shaft 12 to prevent rotation. The washer 23b is in contact with the stopper 12a formed on the support shaft 12 and is restricted in the axial direction.

  The above-described pressure detection member 21 can be displaced with respect to the rear flange portion 3c independently without displacing the flange portion, and each protruding portion 21a protruding from the fishing line regulating surface 3e of the rear flange portion 3c. Since the pressure is received by the fishing line that is wound, the pressing force is generated toward the axial braking member 23 side (generated outwardly in the axial direction of the flange portion by the fishing line wound around the fishing line winding body). The pressing force due to the fishing line winding (also referred to as “fishing winding pressure”) is applied. In this case, since the four protruding portions 21a protrude along the radial direction, the fishing line winding that acts on the pressure detecting member 21 when the amount of the wound fishing line is large (when the winding diameter is large). The landing pressure increases, and when the amount of fishing line to be wound is small (when the winding diameter is small), the fishing line winding pressure acting on the pressure detection member 21 decreases accordingly.

  As described above, the fishing line winding pressure acting on the pressure detection member 21 changes according to the winding amount of the wound fishing line, and accordingly, the braking force acting on the spool 3 via the braking member 23. Will change. In other words, this means that the braking force applied to the spool 3 by the braking device 15 is adjusted (corrected) by the winding diameter of the fishing line.

  Specifically, the spool 3 is wound around the fishing line winding body 3a of the spool 3 as shown in FIGS. 6 to 8 in a state where a predetermined braking force is applied to the spool 3 by the braking device 15. The fishing line winding pressures Fa, Fb, Fc acting on the pressure detection member 21 in accordance with the amount of the fishing line satisfy Fa <Fb <Fc. At this time, the tension acting on the fishing line due to the difference in the moment of the fishing line winding diameter position from the support shaft 12 is usually more gradually in the state shown in FIGS. 7 and 6 than in the state shown in FIG. Although the tension becomes stronger (the tension gradually increases as the fishing line is unwound), the braking force acting on the spool 3 is weak when the above-described braking force adjusting unit 20 has a small spool diameter as shown in FIG. As shown in FIGS. 7 and 8, since the braking force acting on the spool 3 increases as the spool diameter increases, the tension acting on the fishing line is made constant even if the fishing line diameter changes. Is possible.

  Therefore, during actual fishing, even if the fishing line is sent out when the device is thrown in, or even if the fish is hooked and the fishing line is fed out, the tension acting on the fishing line is fixed, so troubles such as cutting the fishing line and cutting the fish are prevented. It becomes possible to do. Further, the pressure detection member 21 constituting the braking force adjusting unit 20 is configured separately from the spool 3 and is displaced (slidably displaced along the axial direction) with respect to the flange portion in a fixed state. Since there is no need to bend the flange portion of the spool as in the prior art, there is no restriction on the material, shape, dimensions, etc. of the spool 3, and the degree of design freedom is not reduced. Further, since the flange portion is not deformed, the spool stroke does not change during winding of the fishing line, and the wound state is not adversely affected.

The above-described embodiment can be modified as follows, for example.
FIG. 9 is a cross-sectional view of a spool showing a first modification.

  In the above-described embodiment, the spool 3 rotates the front knob 16 of the front drag device (braking device 15) so that a desired braking force is applied to the support shaft 12 and is applied by the braking force adjusting unit 20. The braking force is adjusted according to the bobbin diameter, but the braking force adjustment unit 20 may have a function as a front drag device.

  Specifically, the spool 3 may be supported on the support shaft 12 so as to be movable in the axial direction with respect to the support shaft 12 by rotating the front knob 16. That is, the front knob 16 is held against the front end surface of the spool 3, and the spool 3 is moved to the braking member 23 side by rotating the front knob 16, so that the front knob 16 is rotated. In addition, the back surface of the rear flange portion 3c of the spool 3 can press the braking member 23 via the pressure detecting member 21 (see FIG. 2). A braking force can be generated.

  According to such a configuration, the configuration of a braking device (front drag device) that applies a desired braking force to the spool 3 is simplified and the weight of the spool portion can be reduced.

  FIG. 10 is a cross-sectional view of a spool showing a second modification.

  In the above-described embodiment, the washer 23b constituting the braking member 23 of the braking force adjusting unit 20 is applied to the stopper 12a formed on the support shaft 12 and restricted in the axial direction. However, as shown in FIG. The stopper 3g may be provided on the inner surface of the third skirt portion 3d, and the outer peripheral region of the washer 23b may be applied to this portion to restrict axial movement.

  FIG. 11 is a cross-sectional view of a spool showing a third modification.

  In the above-described embodiment, the braking force adjusting unit 20 is provided in the rear flange portion 3c. However, the braking force adjusting unit 20 having the same configuration may be provided in the front flange portion 3b. In this case, by rotating the front knob 16, the central portion of the washer 23 b presses the braking portion 17 of the braking device 15, and a desired braking force can be applied to the spool 3. Of course, even in such a configuration, the braking force adjusting unit 20 may also have the function of the braking device 15 as in the modification shown in FIG. 9.

  Although the embodiment of the present invention has been described above, the present invention is not limited to the configuration of the above-described embodiment, and can be configured as follows, for example.

  The pressure detection member 21 described above has a protruding portion protruding from the restriction surface of the flange portion, and if the fishing line winding pressure corresponding to the winding diameter can be detected, the shape of the protruding portion and the interval formed in the circumferential direction, or The number and the like can be modified as appropriate. Moreover, if the protrusion part protrudes along the radial direction used as the fishing line winding direction, it is possible to detect the fishing line winding pressure according to the winding diameter. Therefore, for example, the protrusions that detect the fishing line winding pressure can be appropriately deformed, for example, by arranging protrusions that are concentric along the circumferential direction along the radial direction. In addition, the braking member 23 is appropriately deformed in the manner of arrangement, constituent members, materials, and the like of each braking member as long as the fishing line winding pressure detected by the pressure detection member 21 can be applied to the spool 3 as a braking force. It is possible.

  In the above-described embodiment, the front drag system is exemplified as the braking device 15 that applies a desired braking force to the spool 3, but the present invention may be provided on the flange portion of the spool of the dual-bearing reel. good.
