TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing reel capable of drag adjustment, and more particularly to a structure capable of accurately returning a drag force once set even after spool free.
[0002]
[Prior art]
Especially when catching fish of medium size or more, if you forcibly wind up the fishing line (hereinafter referred to as the line) or lock the rotation of the spool when pulling the fish, the line will be cut or the mouth of the fish will be cut, so-called fish May be separated. On the other hand, if the spool is free and the fish is pulled out and the line is extended, the bait is taken to a complicated place such as a rocky place or seagrass, and it takes root, and ultimately no fishing results can be obtained.
[0003]
Therefore, drag adjustment has been conventionally performed. Drag adjustment is to adjust the frictional force between the brake disc and the friction disc provided between the spool and the motor or the main gear of the handle that applies a rotational force to the spool in the winding direction, that is, to adjust the clutch pressure. When the reverse rotation force in the line feeding direction acts on the spool for a certain time or more, the clutch is slid to reduce the winding speed of the spool or to allow reverse rotation. As a result, even if the rotational force in the winding direction is transmitted to the spool, if the fish pull exceeds the drag force, the clutch slips and the tension (tensile force) of the line is kept below a certain level. Can be prevented. This is just like using a half-clutch when starting up a hill on a car with a clutch.
[0004]
As such a drag adjusting mechanism, a lever drag type and a star drag type are known. In particular, a lever drag type reel having two adjustment knobs of a drag lever and a fine adjustment knob and capable of setting a drag force finely is also known (for example, see Patent Documents 1 and 2).

[Problems to be solved by the invention]
However, the prior art has two major problems. One of them is that it is difficult to accurately reproduce the initially set optimal drag force after spool free. That is, in the lever drag type, the drag force can be adjusted from 0 to the maximum by operating the drag lever. That is, both drag adjustment and spool free adjustment are performed by one lever. For this reason, in the conventional drag lever type reel, it is necessary to return the drag lever to the zero position every time the device is thrown. Thereafter, the drag lever is returned to the initial optimum position. However, since the operation is almost dependent on intuition, it is difficult to always return the drag lever from the 0 position to the same optimum position. In this regard, unless the drag lever is returned to the optimum position, the drag adjustment is strict enough that the adjustment becomes meaningless or has an adverse effect. Further, even for an expert who is familiar with drag adjustment, a series of lever operations from the 0 position to the optimal position return is troublesome. In this way, the drag force once set does not need to be changed at the time of actual fishing, and it is ideal that the drag force is fixed. Is reset.
[0007]
Another problem is that the drag adjustment mechanism has insufficient waterproof and dustproof effects in the related art. That is, since the conventional lever drag type does not employ a seal structure for sealing the braking disk and the friction disk, impurities such as water and dust may enter the drag adjusting mechanism. In particular, when the drag lever is set to the 0 position, the brake disc and the friction disc are separated from each other, and the clutch is in a disengaged state. At this time, if impurities enter between the discs, the friction engagement force and the slipping state change. I will. As a result, even if the drag lever can be returned to the initially set position, the same drag force cannot be obtained, and there is also a problem that the drag adjustment mechanism may fail.
[0008]
The present invention has been made to solve the above-described problem, and an object of the present invention is to provide a fishing reel that can accurately return to an initially set optimal drag force even after spool free. . Another object of the present invention is to protect the drag adjusting mechanism from impurities such as seawater and dust and to enhance the durability and reliability of the mechanism.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, according to the present invention, a main gear rotatably supported on a main shaft using an electric motor and / or a handle as a driving source, a braking disk and a friction disk frictionally engaged with the main gear are provided. A drive shaft rotatably supported by the main shaft such that one end of the drive shaft is connected to the drive shaft; a spool rotatably supported by the drive shaft; and a drive shaft that is always engaged with the other end of the drive shaft. A clutch gear to which rotational force is transmitted and meshes with the other end of the spool so as to be able to engage and disengage; and a cam which slides the clutch gear so as to mesh with the other end of the spool to turn on and off the rotational force transmission. And a clutch lever for operating the cam, while moving the drive shaft to the main gear side via a drag adjusting spring. A drag adjusting screw that slides in the axial direction as much as possible, and a drag adjusting screw that is screwed with the drag adjusting screw and slides the drag adjusting screw in the axial direction to adjust the frictional engagement force between the brake disc and the friction disc. A fishing reel was constituted by the knob. In this means, by connecting (engaging) the clutch gear with the spool, the rotational force of the drive shaft is transmitted to the spool via the clutch gear, and the spool is wound in the winding direction using the electric motor or the manual handle as a drive source. Rotate. The clutch gear is selectively engaged with or disengaged from the spool by operating a clutch lever. On the other hand, drag adjustment is performed by a completely different mechanism. That is, drag adjustment is performed by operating the knob. As described above, according to the present invention, since the rotational force transmission mechanism and the drag adjustment mechanism of the clutch gear with respect to the spool do not interfere with each other, the drag force initially set even after the clutch lever is operated to set the spool to a free state. Is correctly restored.
[0010]
Further, a cover member for sealing the brake disc and the friction disc is provided at a connection portion between the main gear and the drive shaft. According to this means, it is possible to avoid the intrusion of impurities such as moisture, dust, and dust between the connecting portion between the main gear and the drive shaft, which is the main point for generating the drag force, that is, between the friction disc and the braking disc. .
[0011]
Further, a return spring for urging the clutch gear in a direction away from the other end of the spool is provided. According to this means, the clutch gear can be surely separated from the spool, and the turning on / off of the rotational force transmission mechanism can be more reliably performed.
[0012]
Further, according to the present invention, the drag adjusting spring is supported between a back end of an inner hole formed in the drive shaft and a flange of a bush slidably inserted into the main shaft, and the end face of the bush and the drag adjusting screw are supported. A return spring between the slide plate, which is inserted into the bush at the end face of the flange and the drag adjusting screw, and is engaged with the clutch gear and slides on the bush. The return spring and the drag adjustment spring are employed such that the drag adjustment spring is not compressed by the compression force of the return spring when the clutch gear and the other end of the spool are engaged. According to this means, since the drag adjusting spring and the return spring are provided inside the inner hole formed in the drive shaft and on the same main shaft, the reel structure is rationalized, and this kind of reel is downsized. , Which contributes to simplifying the structure. Moreover, by optimizing the elasticity of the drag adjusting spring and the return spring, it is possible to more reliably avoid interference between the rotational force transmitting mechanism and the drag adjusting mechanism.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a sectional view showing the entire fishing reel according to one embodiment of the present invention. In this embodiment, a dual-bearing electric reel is shown. In this embodiment, even if a certain structure is composed of a plurality of members, those which are regarded as the same members in terms of their functions, for convenience of explanation, include a common member including FIG. Hatch processing was performed. Further, in this embodiment, only a structure indispensable for configuring the present invention will be described, and a configuration common to a conventional fishing reel will be omitted as appropriate. Examples are hand-wound handles and level wonders.
[0014]
In FIG. 1, reference numeral 1 denotes a main shaft having both ends fixed non-rotatably, 2 a main gear rotatably supported by the main shaft 1, 3 an electric motor, and a power of the electric motor 3 which is a pinion gear 4; The power is transmitted to the main gear 2 via the gears 5 and 6. The main gear 2 constitutes a one-way clutch that is rotated only by the ratchet 7 in the line winding direction.
[0015]
Reference numeral 8 denotes a drive shaft rotatably inserted into the main shaft. The drive shaft 8 is connected to the main gear 2 via a lining 9 with a constant frictional engagement force. Specifically, a rim 8b provided with a clutch surface 8a (friction disk) is formed at the left end of the drive shaft 8, and the lining 9 (braking) is formed by the clutch surface 8a and the clutch surface 2a (friction disk) of the main gear 2. Disc) is sandwiched, and a clutch mechanism that can adjust the frictional engagement force of the clutch surfaces 8a and 2a with the lining 9, that is, the drag force, by a drag adjustment mechanism described later. Normally, when the so-called clutch is engaged, the rotational force of the main gear 2 is transmitted to the drive shaft 8 as it is. However, when the fish pull exceeds the frictional engagement force, that is, the drag force, the electric motor Even if 3 is driven, the clutch slips and the rotation speed of the drive shaft 8 becomes slower than that of the main gear 2, the drive shaft 8 stops, or the drive shaft 8 rotates reversely.
[0016]
In this embodiment, in order to protect the clutch mechanism, that is, the lining 9 and the clutch surfaces 8a and 2a from impurities such as water and dust, the clutch mechanism is sealed by a cover member 10. More specifically, as shown in FIG. 2, the periphery of the cover member 10 is formed in a U-shaped cross section, a pin 10a at one end is inserted and fixed to the main gear 2, and a channel portion 10b at the other end. Is hooked on an annular projection 8c formed on the rim 8b of the drive shaft 8 to assemble the clutch mechanism. Further, an O-ring 10c is provided between the channel 10b and the annular projection 8c. Although the cover member 10 blocks water, dust, and the like from entering the clutch mechanism, it goes without saying that the cover member 10 does not prevent the operation of the drive shaft 8 and the main gear 2.
[0017]
Further, since the frictional engagement force between the friction disk and the brake disk also changes due to heat, in order to prevent the heat from being trapped in the clutch mechanism, the main gear 2 and the rim 8b of the drive shaft 8 are highly radiated. It is preferred to be composed of metal.
[0018]
Next, in FIG. 1, reference numeral 11 denotes a spool rotatably inserted into the drive shaft 8, which is a member for winding and feeding out a line, as is well known. As is clear here, in the present invention, the spool 11 is not directly connected to the main gear 2 and the drive shaft 8. Therefore, in the present invention, in order to transmit the rotational force of the drive shaft 8 to the spool 11, as described later, the first cam 14 having the clutch gear 12, the clutch lever 13 attached thereto, and the first cam 14 in cam contact with the first cam 14 are provided. The rotational force transmission mechanism including the two cams 15 enables the spool 11 to be selectively connected to and disconnected from the drive shaft 8 (turn on / off the rotational force transmission mechanism).
[0019]
Further, in FIG. 1, reference numeral 16 denotes a drag adjustment knob provided non-movably and rotatably on the side opposite to the clutch mechanism of the reel, and 17 is reversely threadedly engaged with an internal screw 16a formed on the knob 16. This is a drag adjustment screw having a cylindrical shape formed with an outer screw 17a. Specifically, while the drag adjusting screw 17 is locked by engaging with the engaging portion 1 a of the main shaft 1, the screw is screwed with the knob 16. The adjusting screw 17 slides in the axial direction without rotating. The sliding motion of the drag adjusting screw 17 is transmitted to a drag adjusting spring 19 via a bush 18 with which the end face of the drag adjusting screw 17 abuts, and the compression force of the drag adjusting spring 19 is used to drive the drive shaft. 8 is axially moved to the above-mentioned clutch mechanism side. That is, in the present invention, the drag adjusting mechanism is constituted by these members 16 to 19. The drag adjusting spring 19 is interposed between the flange 18a of the bush 18 and the spring receiving member 20 disposed at the inner end 8d of the drive shaft 8.
[0020]
Next, the mechanism for transmitting the torque between the spool 11 and the drive shaft 8 will be described. The mechanism includes the clutch gear 12, the clutch lever 13, the first cam 14, and the second cam 15 as main members as described above. As shown in FIG. 3, a cam ridge 14a and a cam groove 15a are formed in a predetermined range on the mating surface so as to engage with each other. When the first cam 14 is rotated by the clutch lever 13, the engagement between the cam ridge 14a and the cam groove 15a is released, and the cam ridge 14a presses the second cam 15, so that the second cam 15 is pivoted. Slide in the direction. As shown in FIG. 4 (a), the mating surface of the second cam 15 has a fitting hole 15b at an engaging position between the cam ridge 14a and the cam groove 15a and a pressing position (sliding position) by the cam ridge 14a. As shown in FIG. 4B, a mating surface of the first cam 14 has a built-in plunger 14b that can be elastically fitted into the fitting holes 15b and 15c. With this configuration, the user can recognize the operation range (rotation range) of the clutch lever 13.
[0021]
On the other hand, as shown in FIG. 5, the clutch gear 12 is provided with a flange 12b integrally provided at an end of a cylindrical body 12a, and a notch groove 12c which is opened at a tip end is formed in the cylindrical body 12a. A crown gear 12d is provided on the flange 12b. With respect to the clutch gear 12, the drive shaft 8 is formed at its end with an engaging projection 8e which is always engaged with the notch groove 12c. Since the clutch gear 12 slides in the axial direction by receiving the sliding movement of the cam 15, the notch groove 12c is formed at a depth capable of absorbing the sliding length. A crown gear 11b is formed on the end face of the rotational force transmitting mechanism side rim 11a of the spool 11 so that the clutch gear 12 can be engaged with the crown gear 12d of the clutch gear 12 so that the clutch gear 12 is connected to the spool 11 by the sliding movement. I have.
[0022]
The operation of the rotational force transmission mechanism having the above configuration will be described with reference to FIGS. FIG. 6 shows a state in which the rotational force transmission mechanism is released and the spool 11 is free to rotate. That is, when the clutch lever 13 is at the predetermined position, the cam ridge 14a of the first cam 14 and the cam groove 15a of the second cam 15 are engaged, and in this state, the second cam 15 slides the clutch gear 12. As a result, the crown gear 12d of the clutch gear 12 is separated from the crown gear 11b of the spool 11. 6 and 7, reference numeral 21 denotes a return spring of the rotational force transmission mechanism, which is supported by end faces of the holding plate 23 supported by the flange 18a of the bush 18 via the bearing 22 and the drag adjustment screw 17, and It is interposed between slide plates 24 slidable on the bush 18. Further, the slide plate 24 is engaged with the inner hole step 12 e of the clutch gear 12, slides on the bush 18 in conjunction with the clutch gear 12, and compresses the return spring 21.
[0023]
The connection of the spool 11 in the rotation free state to the drive shaft 8 to transmit the rotational force on the main gear 2 side is performed by operating the clutch lever 13 as shown in FIG. That is, when the clutch lever 13 is rotated, the first cam 14 rotates, and the second cam 15 is axially moved in a direction away from the first cam 14 by the pressing force of the cam peak 14a. The axial movement of the second cam 15 is transmitted to slide the clutch gear 12 toward the spool 11 via an appropriately provided bearing 25, and the crown gear 12d of the clutch gear 12 meshes with the crown gear 11b of the spool 11. As a result, the rotational force of the drive shaft 8 is transmitted to the spool 11 via the clutch gear 12, and the spool 11 can be driven by the electric motor 3 in the winding direction. Normally, drag adjustment is performed in this state, and after catching the fish, when re-entering the tackle, the clutch lever 13 is operated in the opposite direction to the above connection in order to make the spool 11 free to rotate. As a result, the cam ridges 14a and the cam grooves 15a of the first cam 14 and the second cam 15 are engaged, and the clutch gear 12 is pushed back to a predetermined position via the slide plate 24 by the elastic restoring force of the return spring 21. The clutch gear 12 and the crown gears 12d and 11b of the spool 11 are separated from each other, and the connection between the clutch gear 12 and the spool 11 is released.
[0024]
The return position of the return spring 21 is regulated by the drag adjusting screw 17 of the drag adjusting mechanism. Therefore, when drag adjustment is performed with the clutch gear 12 and the spool 11 connected, the end face position of the drag adjustment screw 17 changes, and the return position of the return spring 21, that is, the return position of the clutch gear 12, also changes strictly. However, since the moving distance of the drag adjusting screw 17 during drag adjustment is very small, the moving distance can be ignored. That is, the movement of the drag adjusting screw 17 has no effect on the return of the clutch gear 12 to the return position, and the connection between the clutch gear 12 and the spool 11 is reliably released at the return position.
[0025]
On the other hand, when the clutch gear 12 and the spool 11 are connected, the return spring 21 is compressed, and the compression force is transmitted to the drag adjusting spring 19 via the holding plate 23, the bearing 22 and the flange 18 a of the bush 18. However, the drag adjusting spring 19 has a sufficiently larger resilient force than the return spring 21. Therefore, the drag adjustment spring 19 is not compressed by the compression force of the return spring 21, and as a result, the drag adjustment is not performed when the clutch gear 12 and the spool 11 are connected.
[0026]
As described above, in the present invention, the drag adjusting mechanism and the rotational force transmitting mechanism are integrated on one of the spools 11 such that the drag adjusting spring 19 and the return spring 21 are continuously provided on the main shaft 1, but they do not interfere at all. Instead, they perform substantially independent actions. Therefore, even if the rotation transmission mechanism is operated, the drag adjustment is not performed, and even if the drag adjustment is performed, the rotation transmission mechanism is not operated. As a result, the drag adjustment is performed in the driving state of the spool 11, and then the spool 11 is temporarily stopped. Even if the driving state is changed to the free state, the initially set drag force is always maintained.
[0027]
In the above embodiment, the present invention is applied to the electric reel, but may be applied to a manual reel.
[0028]
【The invention's effect】
As described above, according to the present invention, the mechanism for switching the spool to free rotation and the drag adjustment mechanism are configured in separate and independent states that do not interfere with each other. Thus, it is possible to always return to the initially set drag force. For this reason, even if it is a beginner, if only the first time the expert makes the most suitable drag adjustment, the fishing can be enjoyed with the electric reel program almost left to the rest, and the expert or professional (fisherman etc.) ) Also eliminates the need to re-adjust the drag force each time the spool is free, so that more time can be devoted to fishing. Further, since the disk for determining the drag force is sealed by the cover member, the intrusion of impurities is prevented, so that the durability and reliability of drag adjustment can be improved.
