Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a double-bearing type reel for fishing which is intended to prevent a yarn entanglement phenomenon (backlash phenomenon) when releasing a fishing line (during casting).
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a double-bearing type reel for fishing has been provided with various backlash prevention mechanisms in order to prevent over-rotation of a spool when a fishing line is released. As a general one, a friction brake device using centrifugal force and a magnetic brake device using magnetic force are known.
[0003]
Since the friction braking device has a characteristic that the friction braking force changes secondarily, the braking force suddenly changes with respect to the rotation speed of the spool. There are problems such as a decrease in distance and a tendency to cause a backlash phenomenon due to excessive release of fishing line due to a sudden decrease in friction braking force at the end of casting. Further, the magnetic brake device has a characteristic that a braking force is generated approximately in proportion to the rotational speed of the spool, so that the backlash phenomenon is less likely to occur than the friction brake, but when the spool rotational speed at the end of casting is reduced. However, there is a problem that the flying distance of the device cannot be increased and the short casting performance is inferior.
[0004]
Therefore, in order to solve these problems, Japanese Patent Application Laid-Open No. 10-262519 discloses a magnetic brake device according to the rotation speed of the spool in order to prevent a decrease in the flying distance of the mechanism that occurs at the initial and final stages of casting. Thus, a technique is disclosed in which the distance between the magnet and the conductor can be changed and the closest distance between the magnet and the conductor can be adjusted.
[0005]
According to this magnetic brake device, since the spool rotational braking force generated by the magnetic braking action at the initial stage and the final stage of casting is suppressed, the flying distance of the device can be improved, and the backlash phenomenon can also be prevented. become able to.
[0006]
[Problems to be solved by the invention]
However, the technology disclosed in the above publication is a structure that suppresses the spool rotation braking force at the initial and final stages of casting, so full casting was performed in an environment in which it is difficult to obtain the flying distance of the device (for example, under strong winds). In this case, the fishing line is excessively released and the backlash phenomenon is likely to occur. Also, for beginners who do not focus on the flying distance of the mechanism, the summing operation is unfamiliar, so the backlash phenomenon tends to occur unless a certain amount of spool rotation braking force is given at the beginning and end of casting. End up.
[0007]
The present invention has been made on the basis of the above-described problems, and is a double bearing for fishing having a backlash prevention mechanism capable of performing optimum spool rotation speed control setting according to the conditions of fishing grounds and the user's request. An object is to provide a mold reel.
[0008]
[Means for Solving the Problems]
In order to achieve such an object, the double-bearing type reel for fishing according to the present invention supports the spool rotatably via a spool shaft between the side plates of the reel body, and the spool is in a fishing line winding state and a fishing line. A clutch mechanism that can be selectively switched to a released state, a conductor supported on the spool shaft via a support, and a reel that is provided on the reel body and rotates the spool by applying a magnetic force to the conductor. And a magnet that can move in the axial direction of the spool in accordance with an increase / decrease in the rotation speed of the spool, and controls the rotation speed of the spool by increasing / decreasing the magnetic force applied to the conductor by the magnet. A switching mechanism for switching between a movable state and a non-movable state, wherein the spool rotational speed control unit is movable in the axial direction of the spool. A long groove formed along the axial direction from the end surface on the spool side of the support body toward the frame side, a short groove formed adjacent to the long groove, a pin protruding from the spool shaft, and the support A biasing member that biases the body toward the spool, and the support is rotated while moving in the axial direction against the biasing force of the biasing member, so that the long groove or the short groove and the The switching mechanism can be switched by selectively engaging a pin.
[0009]
According to the above configuration, the switching mechanism is operated according to the demands of the fishing ground and the user to switch between the state where the braking force does not act on the spool at the initial and final stages of casting and the state where the braking force always acts on the spool. It is done.

A driving force transmission mechanism 20 is disposed between the left frame 2a and the left side plate 3a to transmit the rotational movement of the handle 10a to the spool shaft 6. The drive force transmission mechanism 20 is rotatably supported between the left frame 2a and the left side plate 3a via a bearing while engaging with the drive gear 21 rotatably attached to the handle shaft 10 and the drive gear 21. And a pinion 22.
[0014]
A circumferential groove 22a is formed on the outer periphery of the pinion 22, and a clutch plate that is movable in the axial direction by a clutch operating member (not shown) constituting the clutch mechanism is engaged with the circumferential groove 22a. ing. In this case, by operating the clutch operating member to move the pinion 22 in the axial direction, the driving force transmission state (clutch ON state) as shown in FIG. 1 or the spool free when the pinion 22 is disengaged from the spool shaft 6 The rotation state (clutch OFF state) can be switched. The return from the clutch OFF state to the clutch ON state can be performed not only by the operation of the clutch operation member but also by the winding operation of the handle 10a.
[0015]
The drive gear 21 is engaged with a drag mechanism 25 that applies a drag force to the spool 6a when a fishing line is unwound from the spool 6a during fishing. The drag mechanism 25 includes a friction plate, a lining material, and the like. The drag mechanism 25 is pressed against the drive gear 21 with a predetermined pressing force by rotating the drag operation member 27 attached to the handle shaft 10. A predetermined drag force is generated between the handle shaft 10 and the drive gear 21 by the pressure acting on the ratchet 28 that rotates integrally with the handle shaft 10.
[0016]
A level wind device having a fishing line guide portion 30 and a reciprocating mechanism 31 is provided between the left and right frames 2a and 2b. By rotating the handle 10a, the spool 6a is provided with the fishing line guide portion 30. The fishing line is wound evenly. In the level winder of the present embodiment, the fishing line guide portion 30 and the reciprocating mechanism 31 are arranged separately on the front and rear of the spool 6a, but these may be arranged on the front of the spool 6a. .
[0017]
A backlash prevention mechanism 40 is provided on one end side of the spool 6a (spool shaft 6) of the double-bearing fishing reel configured as described above so as to prevent the spool 6a from over-rotating when the fishing line is fed. ing.
[0018]
The backlash prevention mechanism of the present embodiment is provided on the annular conductor 41 that rotates integrally with the spool 6a (spool shaft 6) and the reel body (right frame 2b), and when the annular conductor 41 is inserted, A magnet 42 that brakes the rotation of the spool 6a by applying a magnetic force to this, and a magnetic force that can move along the spool shaft in accordance with an increase or decrease in the rotation speed of the spool 6a and that the magnet 42 acts on the conductor 41. Spool rotation speed control means 45 that controls the rotation speed of the spool 6a by increasing or decreasing is provided. The rotational speed control means 45 can be moved in the axial direction of the spool by a switching mechanism 60 described later (a state in which the magnetic force acting on the conductor 41 can be increased or decreased according to the increase or decrease of the rotational speed of the spool 6a). And can be selectively switched to a state where it cannot move (a state where a magnetic force is always applied to the conductor 41).
[0019]
Hereinafter, the backlash prevention mechanism 40 described above will be described.
2 to 4 are views showing a backlash prevention mechanism provided in the fishing double bearing type reel shown in FIG.
[0020]
The spool rotation speed control means 45 includes a support 46 that rotates integrally with the spool shaft 6 and is movable along the axial direction. The support 46 is formed in a collar shape, and a biasing spring 47 is engaged with the bottom of a recess formed in the end surface portion of the support 46 so as to be constantly biased toward the spool. Further, the support 46 is formed with a support portion 46a protruding in the radial direction at a predetermined interval, and the annular conductor 41 is fixed to the front end side of the support portion. Further, a centrifugally moving member 48 is supported on each support portion 46a so as to be movable in the radial direction. When the spool shaft 6 (support body 46) rotates together with the spool 6a, the centrifugal force causes the radial direction. It moves to the outside.
[0021]
A taper 6b that gradually increases in diameter toward the right frame 2b is formed on the back surface side of the fishing line winding surface of the spool 6a, and when the centrifugally moving member 48 moves radially outward, the outer surface thereof is Surface contact is made with the taper 6b. That is, when the rotational speed of the spool shaft 6 (spool 6a) is improved, the centrifugal movement member 48 moves in the radial direction according to the centrifugal force, and moves toward the right frame 2b along the taper 6b.
[0022]
The magnet 42 includes a pair of annular magnetic bodies 42a and 42b at a predetermined interval so that the annular conductor 41 can be inserted and removed, and each magnetic body is composed of an S-pole and an N-pole magnet. It becomes the structure arranged alternately. The outer magnetic body 42a is rotated by a predetermined range by rotating a dial 42c (see FIG. 1) exposed from the right side plate 3b, and an annular conductive member inserted within a predetermined interval. The braking force acting on the body 41 can be adjusted.
[0023]
The conductor 41 is aligned so as not to be inserted between the magnetic bodies 42a and 42b as shown in FIG. 2 when the spool shaft 6 does not rotate in the fishing line discharge direction.
[0030]
Figure 5 Optimum 7 is a diagram showing an embodiment of a double-bearing type fishing reel, shows anti-backlash mechanism incorporated into such fish double-bearing type reel fishing. In the following description of the backlash mechanism, portions different from the backlash prevention mechanism shown in FIGS. 2 to 4 will be described, and the same components are denoted by the same reference numerals and description thereof is omitted. .
[0031]
The rotational speed control means 45 ′ of the backlash prevention mechanism of this embodiment includes a support body 56 that rotates integrally with the spool shaft 6 and is movable along the axial direction. The support 56 is formed in a collar shape and is always urged toward the spool side by an urging spring 47. The support 56 is formed with a support portion 56a that protrudes in the radial direction at a predetermined interval, and an annular conductor 41 is fixed to the front end side of the support portion. Each support portion 56a supports a centrifugal movement member 48 so as to be movable in the radial direction. When the spool shaft 6 (support 56) rotates together with the spool 6a, the centrifugal force causes the radial movement direction. It moves to the outside.
[0032]
Further, a tapered taper 41a is formed on the outer periphery of the front end of the conductor 41 so that the adjustment range of the braking force is widened. That is, by forming such a taper 41a, it is possible to effectively apply a braking force particularly during a short cast (pitching) of the low-speed rotation of the spool.
[0033]
Next, the configuration of the switching mechanism 60 'that selectively switches between the state in which the rotation speed control means 45' can be moved in the axial direction of the spool and the state in which it cannot be moved will be described.
[0034]
The switching mechanism 60 'includes a long groove 56b formed along the axial direction from the end surface on the spool side of the support 56 toward the right frame 2b, and a short groove 56c formed adjacent to the long groove 56b. Each pin is engaged with a pin 6g that is selectively formed on the spool shaft 6 in each groove.
[0035]
Specifically, when the pin 6g is engaged with the long groove 56b, as shown in FIGS. 5 and 6, the support 56 (conductor 41) is urged according to the increase or decrease of the rotational speed of the spool 6a. The spring 47 can move in the axial direction against the urging force of the spring 47. Further, the right plate is removed from the reel body, the spool 6a is taken out, the support 56 is rotated while moving against the urging force of the urging spring 47, and the pin 6g is engaged with the short groove 56c. Movement of the body 56 in the axial direction is restricted. In this restricting position, as shown in FIG. 7, the conductor 41 is always located within the interval between the pair of annular magnetic bodies 42a and 42b.
[0036]
As described above, according to the switching mechanism 60 ′ of the present embodiment, the switching between the moving state and the immovable state of the rotation speed control unit 45 ′ is performed only by rotating the support 56. Will improve.
[0046]
As described above, the embodiments of the present invention have been described. However, according to the present invention, the rotation speed control means for moving the conductor in the spool axis direction according to the rotation speed of the spool is provided so that the conductor is always positioned in the magnetic body. If switching is possible so that the braking force is applied, the configuration of the switching mechanism can be variously modified. Moreover, the double bearing type reel for fishing shown in FIG. 1 is only an example, and various components are not limited to those shown in FIG.
