Abstract

PROBLEM TO BE SOLVED: To provide a double bearing reel that can easily prevent a backlash without requiring thumbing, is excellent in a flying distance in casting by adopting a structure having little friction structurally, is inexpensive and hardly causes failures by simplifying the structure, and is free from a risk of breakage of a fishing line by adopting a mechanism that a fishing line delivery speed and a fishing line discharge speed are always equivalent.SOLUTION: A drive roller 6 is provided that contacts a spool fishing line wound surface 31 and rotates at the same circumferential speed as the circumferential speed of the spool fishing line wound surface 31. By holding a fishing line 2 to be discharged between the drive roller 6 and the spool fishing line wound surface 31, the fishing line 2 is forcibly discharged by the friction force between the drive roller 6 and the fishing line 2, and the torque of the drive roller 6.

Description

  The present invention relates to a fishing dual-bearing reel provided with a device that prevents backlash that occurs during casting or the like by a mechanical structure.

  In a fishing double-bearing reel (hereinafter also simply referred to as “double-bearing reel”), from the moment of casting, the spool begins to rotate vigorously by being pulled by the fishing line with the device, and then continues to rotate due to the inertia of the spool itself. . On the other hand, when the thrown-out device stalls due to landing or the like, the tension of the fishing line caused by the inertia of the device decreases, and the amount of fishing line that is pulled by the device and discharged from the reel decreases. As a result, the length per unit time of the fishing line fed from the spool (hereinafter referred to as “fishing line feeding speed”) is the length per unit time discharged from the reel (hereinafter referred to as “fishing line discharging speed”). An excess state (spool over-rotation state) occurs. In the spool over-rotation state, the fishing line is excessively fed from the spool, and as a result, a phenomenon occurs in which the fishing line is entangled with the spool. This is called backlash.

  As a means to prevent the backlash, there is a means (summing) for casting while adjusting the tension of the fishing line artificially, but since it is a relatively advanced technique difficult for beginners, both bearing reels themselves Therefore, it is highly desired to prevent backlash by the structure, and several structural means for preventing backlash have been proposed.

  Such structural means include means for controlling the spool rotation speed with a centrifugal brake or the like to suppress spool over-rotation (spool rotation control system), and the fishing line discharge speed from the reel is the same as the fishing line feeding speed from the spool. As a conventional technique, there is a means (a fishing line discharging mechanism system) for providing a forced discharging mechanism that does not fall below the fishing line discharge end of the reel.

  In the spool rotation control system (see Japanese Patent Application Laid-Open No. 7-274782), the reel unit price is high due to the complicated structure, and the brake is applied to prevent over-rotation of the spool, thus increasing friction and casting. There is a big problem that the flight distance is reduced. In addition, you may need to get used to the operation.

  On the other hand, in the conventional fishing line discharge mechanism system (see Japanese Patent Application Laid-Open No. 2001-204323), the discharge driving roller is structured to interlock with the spool rotation shaft via a gear or a belt. It is fixed by the rotation speed and the gear ratio of the spool shaft and the roller diameter. For this reason, while the fishing line discharge speed is constant even if the spool winding diameter of the spool increases or decreases, the fishing line feeding speed tends to change in proportion to the increase or decrease of the fishing line winding diameter. As a result, a problem of thread breakage due to excessive tension generated in the fishing line is assumed (for example, the gear ratio and the fishing line discharge speed are equalized when the fishing line winding diameter is maximum). Even if the roller diameter is set, the fishing line feed speed is almost constant even if the spool rotation speed increases and the drive roller rotation speed increases in proportion to the decrease in the fishing line winding diameter. Tension will be generated and thread breakage may occur.) In addition, since both speeds are not synchronized, there is a problem that the friction increases and the flight distance is reduced.

JP-A-7-274782 JP 2001-204323 A

  As described above, since the backlash in both bearing reels significantly impairs the operability of the reels, it is strongly required to prevent this. Furthermore, as shown above, in the structural means for preventing backlash in the prior art, the yarn breakage due to the decrease in flight distance due to increased friction, the higher price due to the complicated structure, and the forced discharge of unstable fishing line. And a reduction in flight distance.

  The present invention has been made in view of the above-mentioned problems, and the purpose of the present invention is to prevent backlash easily without requiring summing even for beginners, and at the same time, at the time of casting by making the structure structurally low in friction. It is an object of the present invention to provide a dual-bearing reel that is excellent in flight distance and has a simple structure, is inexpensive, has few failures, and does not have to worry about yarn breakage.

The invention according to claim 1 is a dual-axis reel including a spool on which both left and right shaft ends are rotatably supported by a casing and on which a fishing line is wound, and a fishing line winding surface wound around the spool; A fishing dual-bearing reel is provided with a roller that rotates on the winding surface in synchronism with the rotation of the spool while holding the fishing line to be released by abutting. The discharge structure is referred to as a single roller type discharge mechanism. This makes it possible for beginners to easily prevent backlash without requiring summing, and at the same time, it has a structure with little friction so that it has excellent flying distance during casting and is inexpensive because it has a simple structure. Can reduce failure.
The roller is driven by the frictional force with the fishing line winding surface of the spool, and always rotates at the same rotational speed (same peripheral speed) as the rotational speed (peripheral speed) of the winding surface. Here, since the rotational speed (circumferential speed) of the fishing line winding surface of the spool is equivalent to the fishing line feed speed, the rotational speed (circumferential speed) of the roller is also equivalent to the fishing line feed speed. The fishing line sandwiched between the roller and the spool fishing line winding surface is pulled in the direction in which both rotate by the frictional force (resulting in tension in the fishing line), and is equivalent to the rotational speed (circumferential speed) of the roller. It is forcibly ejected outside the reel at the ejection speed. According to the above discharging mechanism, a fishing line discharging speed which is always equivalent to the fishing line feeding speed from the spool is realized, and there is no fear of thread breakage.
In addition to the roller generating the fishing line discharging force, the both-bearing reel for fishing includes a roller support for rotatably supporting the roller, and the roller so that the roller is brought into contact with the winding surface of the fishing line. It is preferable to comprise an elastic part that repels the support. This also applies to the inventions described in claims 2 and 3 below. As a result, the roller receives an urging force from the elastic portion via the roller support, so that the roller can always be brought into pressure contact with the fishing line winding surface of the spool while following the change in the fishing line winding diameter of the spool. Even if the rotation speed (circumferential speed) of the spool fishing line winding surface is changed by increasing or decreasing the winding diameter of the fishing line, the roller also rotates at a rotational speed (peripheral speed) synchronized (tuned) with the change. become.
Further, it is preferable that the double bearing reel for fishing is provided with a line guide for positioning the fishing line at a position in front of the fishing line to be released by the roller. This also applies to the inventions described in claims 2 and 3 below. As a result, the fishing line to be released can be securely held between the rollers.

  The invention according to claim 2 of the present application is a dual-axis reel including a spool on which both left and right shaft ends are rotatably supported by a casing and on which a fishing line is wound, on which a fishing line is wound around the spool. The first roller rotating on the winding surface in synchronism with the rotation of the spool, and the rotation of the first roller while holding the fishing line to be released by contacting the first roller. A double-bearing reel for fishing is provided with a second roller that rotates in synchronization with the second roller. This discharge structure is referred to as a double roller type discharge mechanism. According to this invention, the fishing line is forcibly discharged on the same principle as the invention according to claim 1 by utilizing the rotation of the first roller and the second roller pressed against the first roller. Thus, the same effects and advantages as those of the first aspect of the invention can be achieved. Further, by adopting this double roller type discharging mechanism, the fishing line can be forcibly discharged more stably than the discharging mechanism according to claim 1 without being affected by irregularities on the fishing line winding surface of the spool.

  According to a third aspect of the present invention, there is provided a dual-axis reel including a spool on which both left and right shaft ends are rotatably supported by a casing and on which a fishing line is wound, and a fishing line winding surface wound around the spool; By abutting, a first roller that rotates on the winding surface in synchronization with the rotation of the spool, a second roller that receives a rotational force from the first roller, and abutting the second roller, A fishing double bearing reel is provided with a third roller that rotates in synchronization with the rotation of the second roller while sandwiching the fishing line to be released. This discharge mechanism is referred to as a triple roller type discharge mechanism. According to this invention, the fishing line is forcibly discharged on the same principle as the discharging mechanism according to claim 1 by utilizing the rotation of the first roller, the second roller, and the third roller. Thus, the same operation and effect as the first aspect of the invention can be achieved. Further, by adopting this triple roller type discharge mechanism, the fishing line can be discharged more stably than the discharge mechanism according to claim 1 without being affected by irregularities on the fishing line winding surface of the spool. Compared with the discharging mechanism according to the above, the fishing line in the reel can be handled smoothly, and the friction can be reduced. If the second roller is driven via a gear or the like, the ratio of the diameter of the first roller to the second roller and the ratio of the number of gear teeth (the above are collectively referred to as the gear ratio) can be arbitrarily set. Therefore, the rotation speed of the second roller (fishing line discharging speed) can be made higher than the rotation speed of the first roller (fishing line feeding speed), and the spool fishing line winding surface and the first roller are taken into consideration while considering thread breakage. The fishing line discharge speed can be set in consideration of slip. Accordingly, it is possible to provide a fishing double bearing reel provided with a fishing line discharging mechanism having a higher backlash prevention effect.

  Furthermore, in the above-described invention, a structure capable of artificially blocking the pressure contact state between the spool fishing line winding surface and the roller (first roller), for example, when a roller support is used, a lever is provided on this to support the spool fishing line winding surface and the roller ( It is also possible to make a structure in which the pressure contact state of the first roller can be artificially interrupted against the elastic force of the elastic body by hand operation. If comprised in this way, addition and interruption | blocking of a fishing line discharge | emission function can be switched as needed. That is, in the present invention, a constant torque is transmitted to the roller (first roller) using the frictional force between the spool fishing line winding surface and the roller (first roller), and this is used for the fishing line discharging force. Therefore, it is possible to eliminate even small friction generated by the discharge mechanism according to the present invention by providing a mechanism for artificially blocking the pressure contact state between the spool fishing line winding surface and the roller (first roller). Thus, it is possible to cope with the use that gives the highest priority to the flight distance during casting (when the clutch mechanism is released). In addition, it is possible to reduce the resistance during the winding operation of the line (when the clutch mechanism is connected), and it is possible to provide both bearing reels that are easier to use.

  Furthermore, in place of the elastic portion in each of the above-described discharge mechanisms, a lever is provided on the roller support so that the spool fishing line winding surface and the roller can be used only when the fishing line needs to be discharged forcibly. The fishing line can be forcibly discharged according to the above principle.

  According to the present invention, it is possible to easily prevent backlash without artificially summing. In addition, since the spool over-rotation is not controlled by applying a braking force to the spool rotation, the friction in discharging the fishing line is reduced, and the flying distance reduction improving effect is produced. Furthermore, since the structure is simple, it is inexpensive and can be reduced in failure. In addition, the fishing line discharge force (tension of the fishing line) is always constant, so that it is possible to improve the prevention of line breakage due to excessive tension generation and the reduction in flight distance due to increased friction.

[Embodiment of single roller type]
1 is a perspective view of a single roller type dual-bearing reel 1-1, FIG. 2 is a front view thereof, FIG. 3 is a bottom view thereof, FIG. 4 is a partially cutaway perspective view thereof, and FIG. is there. As shown in these drawings, the bearing reel 1-1 has a casing 1 in which left and right side walls 1A and 1B are connected by a plurality of connecting portions 1C, and left and right side walls 1A and 1B of the casing 1 at both ends. Is rotatably supported and a spool 3 around which a fishing line 2 is wound, a handle 4 that is installed outside one side wall 1A and rotates the spool 3, and a line winding operation (when a clutch mechanism described later is connected) In addition, a level winder 5 is provided as a basic constituent part by reciprocating in the spool rotation axis direction (reel width direction) in conjunction with the rotation of the spool 3 so that the fishing line is aligned and wound around the spool 3. Further, in addition to these, the both bearing reels 1-1 include a roller (hereinafter referred to as “driving roller”) 6 that generates a fishing line discharging force, and a roller support 7 that rotatably supports the driving roller 6. Forcing a fishing line comprising an elastic portion 8 that repels the roller support 7 so that the drive roller 6 abuts a spool fishing line winding surface 31 described below, and a line guide 9 that positions the fishing line. A discharge mechanism (hereinafter referred to as “discharge mechanism”) A is provided.

  The handle 4 and the spool 3 are connected and forcibly rotated during the winding operation of the line, and a clutch mechanism (not shown) that can be freely rotated by being released by pressing a lever (not shown) during casting. It is linked via

  4 and 5 show in detail a portion of the discharge mechanism A, which is a main part of the bearing reels 1-1. The discharge mechanism A is a driving roller that abuts (pressure contact or elastic contact) with the spool fishing line winding surface 31 wound around the spool 3 and rotates at the same speed as the rotational speed (circumferential speed) of the winding surface 31. 6, a roller support 7 that supports the driving roller 6, an elastic portion 8 provided between the roller support 7 and the casing 1, and positioning of the fishing line 2 to be discharged in the spool rotation axis direction (reel width direction). The line guide 9 is configured. Here, the elastic portion 8 applies an urging force for always bringing the driving roller 6 into contact with (the pressure contact with) the spool fishing line winding surface 31 via the roller support 7.

  The drive roller 6 has, for example, a substantially cylindrical shape (or a substantially columnar shape), and is made of a member such as rubber or resin. Then, it is supported on a roller support 7 described below so as to be rotatable about an axis parallel to the spool rotation axis.

  The roller support 7 is made of, for example, a metal thin plate material, and includes a left and right side plate 7A positioned so as to sandwich the driving roller 6 and a connecting plate 7B that connects one end sides of the left and right side plates 7A. A shaft support portion 7D that rotatably supports the drive roller 6 is provided in an intermediate portion of the left right plate 7A. On the other hand, in the vicinity of the end of the left and right side plate 7A opposite to the end where the connecting plate 7B is connected, there is a shaft portion 7E that pivotally supports the casing 1 (the left and right side walls 1A and 1B). Is provided. The roller support 7 is referred to as a swing arm system. Further, a portion 7 </ b> F that engages with an elastic portion 8 (details will be described later) and receives a biasing force from the elastic portion 8 is provided in the vicinity of the central portion of the left and right side plates 7 </ b> A.

  In addition to the swing arm system such as the roller support 7, the roller support 70 that receives the urging force from the elastic portion 8 is integrated with the drive roller 6 as shown in FIG. You may comprise by the sliding system which slides to the surface 31 direction (up-and-down movement). The roller support 70 according to the sliding method connects the left and right side plates 70A provided with the shaft support portion 70D of the driving roller 6 and the left and right side plates 70A, and abuts the elastic portion 8 to thereby apply a biasing force from the elastic portion 8. The connecting plate 70B that forms the bottom portion 70F that receives the projection and the projecting portion 70C that protrudes downward from the connecting plate 70B in order to form the sliding engagement portion 70E with the casing 1 are provided. Here, the sliding engagement portion 70E with the casing 1 allows the projection 70C of the roller support 70 and the projection 18 provided on the casing 1 side so as to be slidable with each other. It is configured as follows.

  The roller supports 7 and 70 that have received the urging force from the elastic portion 8 are rotatable about a shaft portion 7E with the casing 1 (swing arm system) or slidable in the direction of the spool fishing line winding surface 31. Therefore, the driving roller 6 supported thereby can be brought into contact (pressure contact or elastic contact) so as to follow the spool fishing line winding surface 31. As a result, the drive roller 6 always abuts (pressure contact or elastic contact) with the spool fishing line winding surface 31 even if the fishing line winding diameter of the spool 3 changes, and the fishing line feeding speed associated with the change in the fishing line winding diameter. Synchronously (synchronized) with this change, the motor always rotates at the same peripheral speed as the feeding speed.

  The elastic portion 8 is installed between the roller support 7 and the casing 1 (left and right side walls 1A and 1B) in order to always generate a pressure contact force between the spool fishing line winding surface 31 and the driving roller 6. The elastic portion 8 uses a torsion coil spring having a fixed stroke length in the above example so that the drive roller 6 can move following the spool fishing line winding surface 31, but a compression coil spring, an air spring, Alternatively, other suitable elastic bodies such as leaf springs may be used. For engagement with the casing 1, in the embodiment, the left and right wall surfaces 1 </ b> A and 1 </ b> B are provided with gaps (grooves) so that the axis of the torsion coil spring is coaxial with the rotation axis of the shaft portion 7 </ b> E of the roller support 7. A structure is adopted in which a torsion coil spring is fitted into the gap (groove). On the other hand, the engagement with the roller support 8 has a structure in which one end portion of the torsion coil spring is engaged with the notch provided in the engagement portion 7F.

  The driving roller 6 is always in pressure contact with the fishing line winding surface 31 of the spool 3 due to the urging force generated from the elastic portion 8, so that the driving roller 6 always rotates at the same peripheral speed as the spool fishing line winding surface 31 as described above. In addition, the discharge force of the fishing line 2 (the tension of the fishing line 2) is generated by the frictional force generated by the pressure contact.

  The line guide 9 guides the fishing line 2 to be discharged within the width of the driving roller 6 so that the driving roller 6 is narrower than the spool fishing line winding surface 31. Even if there is, the fishing line 2 to be discharged is prevented from coming off the drive roller 6. The line guide 9 also has a role of guiding the fishing line 2 wound in the back of the spool 3 to the surface. Since the fishing line 2 swings in the range of the entire width of the spool 3 by the movement of the level winder 5, the line guide 9 is provided between the level winder 5 and the driving roller 6. In order to guide more reliably, it may be provided on the discharge side of the driving roller 6 together. In this bearing reel 1-1, an embodiment of a line guide 9 is shown in which a gap for passing a fishing line 2 is provided in the vicinity of the center of a rod-like member attached between the left and right side walls 1A, 1B of the casing 1. However, the method is not limited to the method of fixing to the casing 1, and a line guide 9 may be provided integrally with the roller support 7 (in the center of the connecting plate 7B) like the roller support 7 shown in FIG. Good.

  In both bearing reels having the level winder 5, the fishing line 2 is wound obliquely (spiral) around the spool 3, so the length per unit time of the fishing line 2 that is actually fed out from the spool 3. Is slightly (approximately 1%) longer than the peripheral speed of the spool fishing line winding surface 31. In addition, the fishing line 2 may be wound in a meandering manner in the width direction of the spool 3, thereby causing irregularities on the spool fishing line winding surface 31 (see FIG. 8B), and between the driving roller 6 and the fishing line 2. Due to the gap, no frictional force is generated between the fishing line 2 and the driving roller 6, and there is a possibility that the fishing line 2 cannot be discharged well. Such an event causes the fishing line discharging ability of the discharging mechanism A according to the present invention to be reduced. As a means for solving this phenomenon, it is conceivable to use a substantially cylindrical spool shape in which the central portion is expanded as shown in FIG. With this shape, the central portion of the spool 3 is easily pressed against the driving roller 6. However, the fishing line 2 to be discharged by the line guide 9 is guided to the central portion of the driving roller 6 to discharge the driving roller 6. It is possible to prevent a gap from being generated between the fishing line 2 to be performed. Further, since the apparent spool fishing line winding diameter is increased, the difference (about 1%) between the peripheral speed of the driving roller 6 and the feeding length of the fishing line 2 per unit time can be corrected.

  For the engagement between the elastic portion 8 and the casing 1 (the left and right side walls 1A, 1B or the connecting portion 1C), an adjustment screw 33 or the like that can adjust the urging force of the elastic portion 8 as shown in FIG. 9 is added. You can also. As a result, it is possible to adjust the pressure contact force between the driving roller 6 and the spool fishing line winding surface 31 and the discharge force of the fishing line 2 (tension of the fishing line 2), and it is possible to provide a dual-use dual-bearing reel. Become.

  Next, the operation of the dual-bearing reel 1-1 having the single roller type discharge mechanism A will be described. First, casting is performed in a state where the connection between the handle 4 and the spool 3 is released by pressing a lever (not shown) of both the bearing reels 1-1. As a result, the fishing line 2 wound around the spool 3 is drawn out from the spool 3 vigorously and is sent to the line guide 9 after passing through the level winder 5, and then abuts (pressure contact) with the spool fishing line winding surface 31. The fishing line 2 sandwiched between the rotating driving rollers 6 is pulled in the direction in which both are rotated by frictional force (resulting in tension in the fishing line), and the rotational speed (circumferential speed) of the driving roller 6 Is forcibly ejected to the outside of the reel at an equivalent ejection speed. As a result, a fishing line discharging speed that is always equivalent to the fishing line feeding speed from the spool 3 is realized, so that the stable fishing line 2 can be discharged, and there is no fear of line breakage. As a result, even beginners can easily prevent backlash without requiring summing, and at the same time, since the structure has little friction, the flying distance during casting can be improved.

  In particular, in the case of the dual-bearing reel 1-1, the drive roller 6 is configured to receive a biasing force from the elastic portion 8 via the roller support 7, so that the spool 3 is always in contact with the change in the fishing line winding diameter of the spool 3. The structure is suitable for being brought into pressure contact with the spool fishing line winding surface 31. The bearing reels 1-1 are provided with a line guide 9 for positioning the fishing line 2 at a position before being sandwiched between the driving rollers 6 of the fishing line 2 to be released. It can be securely held by the drive roller 6.

  Needless to say, the bearing reel 1-1 is merely an example of the present embodiment. For example, the structure and installation positions of the drive roller 6, the roller support 7/70, the elastic portion 8, and the line guide 9 are described. In consideration of the structure, positional relationship, etc. of the casing 1, the spool 3, and the level winder 5, specific ones that are suitable for each other are determined. As for the members, the roller support 7/70 is not particularly limited to a metal thin plate material, and may be a metal tube material having a certain strength and rigidity, an injection molded resin, or the like.

  In the discharge mechanism A, a lever is connected to the roller support 7 and the pressing portion of the lever is arranged at a position where it can be operated by hand. When this lever is pressed, the drive roller 6 is wound on the spool fishing line via the roller support 7. If a structure separating from the landing surface 31 is added, the fishing line discharging mechanism can be artificially blocked. As a result, even a slight friction on the fishing line discharging mechanism according to the present invention can be eliminated, and it is possible to cope with a usage method that gives top priority to the flight distance during casting (when the clutch mechanism is released). Further, it is possible to reduce the resistance during the line winding operation (when the clutch mechanism is connected). As a method for connecting the levers, for example, a configuration in which the shape of the rear end portion (the connecting plate 7B side portion) of the roller support 7 is extended to the hand operating portion can be considered.

  Further, the elastic portion 8 in the discharge mechanism A is omitted, and instead, for example, a lever provided on the roller support 7 via a link mechanism is pressed by a finger, whereby the spool fishing line 31 and the driving roller 6 are pressed. It is good also as a structure which press-contacts. As a result, only when the fishing line 2 must be forcibly discharged, the fishing line 2 can be forcibly discharged by pushing the lever at hand. The discharge mechanism is also one embodiment of the present invention.

[Embodiment of double roller type]
FIG. 10 is a side view of the main part of a double roller type double bearing reel 1-2. The discharge mechanism A is in contact (pressure contact) with the spool fishing line winding surface 31 and rotates at the same speed as the rotation speed (circumferential speed) of the winding surface 31 (hereinafter referred to as “drive roller”) 6. A second roller 10 that contacts (pressure contact) with the drive roller 6 and rotates at the same peripheral speed, a roller support 7 that supports the drive roller 6 and the second roller 10, a roller support 7 and the casing 1 An elastic portion 8 provided between the left and right side walls 1A and 1B, and a line guide 9 for positioning the fishing line 2 to be discharged in the spool axis direction (reel width direction). Here, the elastic portion 8 is for always bringing the driving roller 6 into contact (pressure contact) with the spool fishing line winding surface 31 via the roller support 7, and the driving roller 6 and the second roller 10 are always in contact with each other. An urging force is provided to enable contact (pressure contact).

  The drive roller 6 and the second roller 10 are both substantially cylindrical (substantially columnar), for example, and the surface portion is made of a material that is difficult to slip against the fishing line 2 such as rubber or resin. The driving roller 6 and the second roller 10 are both supported by the roller support 7 so as to be rotatable about an axis parallel to the spool rotation axis, and the driving roller 6 is connected to the second roller 10 and the spool fishing line. It arrange | positions so that it may be pinched | interposed into the winding surface 31. FIG.

  The specifications (members, structure, shape, etc.) of the roller support 7 are basically the same as those of the both-bearing reel 1-1, and in addition to this, a shaft for the second roller 10 to rotate and slide. A supporting portion 7G is provided in the vicinity of the shaft supporting portion 7D for rotating and sliding the drive roller 6, and guides the fishing line 2 so that the fishing line 2 is securely sandwiched between the driving roller 6 and the second roller 10. A line guide 11 is provided in the vicinity of the drive roller 6. The line guide 11 is formed of a pipe or the like that is bridged between the left and right side plates 7A.

  FIG. 11 is an enlarged view of the drive roller shaft support portion 7D portion of the roller support 7. FIG. As shown in the figure, the shaft support portion 7D of the drive roller 6 has a shaft insertion hole having a substantially long hole shape, and the drive roller 6 is movable in the major axis direction (direction toward the second roller 10) along with the rotation shaft. It has a possible structure. As a result, when the driving roller 6 is brought into elastic contact with the spool fishing line winding surface 31, the rotational axis of the driving roller 6 is pivotally supported so that the driving roller 6 always makes elastic contact with the second roller 10 with an appropriate elastic contact force. Move in 7D. In addition, this configuration enables adaptation (correspondence) to various thicknesses of the fishing line 2.

  The roller support 7 may be a sliding roller support 70 as described with reference to FIG. 6 of the both-bearing reel 1-1. The specifications (members, structure, shape, etc.) of the sliding roller support 70 are basically the same as those of the sliding roller support 70 shown in FIG. A structure (corresponding to 7G in FIG. 10) is added below the shaft supporting part (corresponding to 7D in FIG. 10) of the drive roller 6.

  The roller support 7 that has received the urging force from the elastic portion 8 rotates about the shaft portion 7E with the casing 1 as a fulcrum (swing arm method) or slides toward the spool fishing line winding surface 31 (sliding method). Then, the driving roller 6 supported thereby moves so as to follow the spool fishing line winding surface 31 whose diameter is changed. As a result, even if the fishing line winding diameter of the spool 3 changes, the driving roller 6 always comes into pressure contact with the spool fishing line winding surface 31 and synchronizes (synchronizes) with the change in the fishing line feeding speed accompanying the change in the fishing line winding diameter. , It always rotates at the same peripheral speed as the feeding speed. At the same time, the second roller 10 in pressure contact with the drive roller 6 always rotates at the same peripheral speed as the feeding speed.

  The elastic portion 8 has a roller support 7 and a casing 1 (both left and right side walls) in order to always generate a pressure contact force between the spool fishing line winding surface 31 and the driving roller 6 and between the driving roller 6 and the second roller 10. 1A, 1B), and the specifications (members, structure, shape, etc.) are basically the same as those of the both bearing reels 1-1. In the example shown in FIG. 10, an elastic portion for pressing the driving roller 6 and the second roller 10 and an elastic portion for pressing the driving roller 6 against the spool fishing line winding surface 31 are formed by one elastic portion 8. It is configured.

  The specifications (member, structure, shape, installation position, etc.) of the line guide 9 are also the same as those of the both-bearing reel 1-1.

  The operation of the double-bearing reel 1-2 having the double roller type discharge mechanism A will be described. First, casting is performed in a state where the connection between the handle 4 and the spool 3 is released by pressing a lever (not shown) of the bearing reels 1-2. As a result, the fishing line 2 wound around the spool 3 is vigorously fed out from the spool 3, passes through the level winder 5, is sent to the line guide 9, and then comes into contact (pressure contact) with the spool fishing line winding surface 31. The fishing line 2 that is sandwiched between the driving roller 6 and the second roller 10 that is in contact (pressure contact) with the driving roller 6 after passing through the line guide 11 and then passing through the line guide 11 The toner is forcibly discharged out of the reel by the frictional force between the driving roller 6 and the second roller 10. At this time, since the feeding speed of the fishing line 2 fed from the spool 3 and the discharging speed of the fishing line 2 are always equivalent, the fishing line 2 is stably discharged. As a result, there is no worry of thread breakage, and the same effect as in the case of the both bearing reels 1-1 is produced.

  The discharging mechanism A (both bearing reels 1-2) shown in FIG. 10 is only an example of a discharging mechanism for a double roller type both bearing reel. Regarding the structure and installation position of each roller (drive roller 6, second roller 10), roller support 7/70, elastic portion 8, and line guide 9, the structure and positional relationship of the casing 1, the spool 3, and the level winder 5, etc. In consideration of the above, determine what is suitable for each other. As for the members, the roller support 7/70 is not particularly limited to a metal thin plate material, and may be a metal tube material having a certain strength and rigidity, an injection molded resin, or the like.

  FIG. 12 is a side view of a main part of a double roller type both-bearing reel 1-3. That is, if possible in layout, the support 13 that supports the second roller 10 may be provided separately from the roller support 7. In this case, an elastic portion 14 for pressing the second roller 10 supported by the support 13 and the driving roller 6 may be provided separately from the elastic portion 8. Providing the support 13 eliminates the need for the shaft insertion hole of the driving roller 6 to have a long hole structure (see FIG. 11), and as a result, the driving roller 6 can be supported more stably. Further, by providing the elastic portion 14, the pressure contact force between the spool fishing line winding surface 31 and the drive roller 6 (force that generates a frictional force that generates drive force) and the pressure contact force between the drive roller 6 and the second roller 10 (fishing line). Can be set individually, and a more efficient fishing line discharging mechanism A with less friction can be provided.

  The support 13 is made of, for example, a metal thin plate, and includes a left and right side plate 13A that is positioned so as to sandwich the second roller 10, and a connecting plate 13B that connects the left and right side plate 13A, and one end portion of the left and right side plate 13A. Near the other end of the left and right side plate 13A is engaged with an elastic portion and a biasing force is provided in the vicinity of the second roller 10 so that the second roller 10 can slide freely around an axis parallel to the spool rotation axis. A receiving portion 13E is provided. Further, a shaft portion 7H with the roller support 7 is provided in the middle portion of the left and right side plates 13A, and is supported by the roller support 7 so as to be rotatable about an axis parallel to the spool rotation axis (the above-mentioned) The support is called a swing arm system). The support 13 does not necessarily have to be pivotally supported by the roller support 7, and the spool rotates on the left and right side walls of the casing 1 so as to form a state in which the second roller 10 to be supported is always in pressure contact with the drive roller 6. It may be pivotally supported so as to be rotatable around an axis parallel to the axis. Further, in place of the swing arm method, a method in which the roller support 7 or the casing 1 is supported so as to always slide in the direction in which the driving roller 6 is in pressure contact (hereinafter referred to as a sliding method) may be employed.

  The support 13 that has received an urging force from the elastic body 8 or the elastic portion 14 rotates or supports the shaft 7 </ b> H with the roller support 7 or the shaft with the casing 1. Slide in the direction of pressure contact with 6. Thus, the state in which the second roller 10 to be supported is always in pressure contact with the driving roller 6 is maintained. The elastic portion 14 gives an urging force for pressing the second roller 10 against the driving roller 6 through the support 13.

  The elastic part 14 is provided between the roller support 7 and the support 13 or between the casing 1 and the support 13 and is configured by an elastic body that engages with them. Unlike the elastic body of the elastic portion 8, the elastic body has no particular problem with the stroke length, and may be an elastic member such as an elastomer in addition to a coil spring, an air spring, or a plate spring. As the locking structure, for example, a structure in which the elastic body 14 is engaged with a convex portion or a concave portion provided on the roller support 7 or the casing 1 and the support 13 can be considered.

  In the discharge mechanism A according to the above-described both bearing reels 1-2 and 1-3, similarly to the above-described both-bearing reels 1-1, on the rear end portion (the side on which the driving roller 6 and the like are attached) of the roller support body 7. If the lever is connected, and the pushing portion of the lever is disposed at a position where it can be operated by hand, and if this is pushed, the drive roller 6 is separated from the spool fishing line winding surface 31 via the roller support 7, a fishing line can be added. It becomes possible to artificially shut off the discharge mechanism. With this mechanism, it is possible to eliminate even a slight friction on the fishing line discharge mechanism according to the present invention, and it is possible to deal with the use that gives the highest priority to the flight distance during casting (when the clutch mechanism is released). Further, it is possible to reduce the resistance during the line winding operation (when the clutch mechanism is connected). As a method for connecting the levers, for example, a method in which the shape of the rear end of the roller support 7 is extended to the hand operating portion can be considered. As for the means for releasing the pressure contact state between the drive roller 6 and the second roller 10, the pressure contact state is automatically released by the above operation in the example of FIG. 10 in which the shaft support portion of the drive roller 6 has a long hole structure. Will be. On the other hand, in the example of FIG. 12 having the support 13 and the elastic portion 14, for example, when the roller support 7 is lowered until the drive roller 6 is separated from the spool winding surface 31, the support 13 is provided in the casing 1. It is possible to consider a method in which the protrusion 19 is pushed up from below and the pressure contact state is thereby released.

  Further, similarly to the double-bearing reel 1-1, the elastic portion 8 in the discharge mechanism A related to the double-bearing reels 1-2 and 1-3 is omitted, and instead, for example, the roller support 7 is connected via a link mechanism. A configuration may be adopted in which the spool fishing line winding surface 31 and the driving roller 6 are pressed against each other by pressing the provided lever with a finger. As a result, only when the fishing line 2 must be forcibly discharged, the fishing line 2 can be forcibly discharged by pushing the lever at hand. The discharge mechanism is also one embodiment of the present invention.

[Embodiment of triple roller type]
FIG. 13 is a side view of an essential part of a triple roller type dual bearing reel 1-4. The discharge mechanism A is in contact (pressure contact) with the spool fishing line winding surface 31 and rotates at the same speed as the circumferential speed of the winding surface (hereinafter referred to as “drive roller”) 6, and the drive roller 6. A second roller 10 that contacts (pressure contact) and rotates at the same peripheral speed, a third roller 12 that contacts (pressure contact) and rotates at the same peripheral speed, and a driving roller 6. A roller support 7 that supports the second roller 10, a support 13 that supports the third roller 12, an elastic portion 8 provided between the roller support 7 and the casing 1 (left and right side walls 1A and 1B), The elastic part 14 is provided between the support 13 and the casing 1. Here, the elastic portion 8 applies an urging force for always contacting the spool fishing line winding surface 31 and the driving roller 6 by moving the driving roller 6 through the roller support 7. The elastic portion 14 provides an urging force for always bringing the second roller 10 and the third roller 12 into pressure contact with each other.

  The drive roller 6, the second roller 10, and the third roller 12 are all substantially cylindrical (substantially columnar), for example, and the surface portion is made of a material that does not slip with respect to the fishing line 2 such as rubber or resin. ing. The driving roller 6 and the second roller 10 are supported by a roller support 7 and the third roller 12 is supported by a support 13 so as to be rotatable about an axis parallel to the spool rotation axis. The driving roller 6 is disposed so as to be sandwiched between the second roller 10 and the spool fishing line winding surface 31, and the second roller 10 is disposed so as to always contact the driving roller 6 with a constant pressure.

  The roller support 7 has the same basic specifications (members, structure, shape, etc.) as the bearing reel 1-1, and is provided with a shaft support 7G for the second roller 10 to rotate and slide. ing. Here, the shaft support portion 7G of the second roller 10 is configured to be coaxial with the shaft portion 7E with the casing 1.

  Further, the roller support 7 may be configured by a sliding roller support 70 as long as layout is possible, as in the case of the double-bearing reel 1-1.

  The roller support 7 that has received the urging force from the elastic portion 8 rotates around the shaft portion 7E with the casing 1 as a fulcrum (swing arm method) or slides in the direction of the spool fishing line winding surface (sliding method). Accordingly, the driving roller 6 to be supported moves so as to follow the spool fishing line winding surface 31. As a result, the driving roller 6 always comes into pressure contact with the spool fishing line winding surface 31 even if the fishing line winding diameter of the spool 3 changes, and synchronizes (synchronizes) with the change in the fishing line feeding speed accompanying the change in the fishing line winding diameter. , It always rotates at the same peripheral speed as the feeding speed. As a result, the second roller 10 pressed against the driving roller 6 always rotates at the same peripheral speed as the feeding speed, and the third roller 12 pressed against the second roller 10 always rotates at the same peripheral speed as the feeding speed. It will be.

  The support 13 is a member for receiving a biasing force from the elastic portion 14 while supporting the third roller 12 and press-contacting the third roller 12 and the second roller 10, for example, a thin plate material, a cast member, or forging It consists of a member or an injection molded resin member. The support 13 is composed of a left and right side plate 13A and a connecting plate 13B that connects them, and the left and right side plate 13A is provided with a shaft support portion 13C so that the third roller 12 can rotate about an axis parallel to the spool rotation axis. The connecting plate 13B is provided with a sliding engagement portion 13D that slides between and supports the casing 1, and a portion 13E that receives an urging force from the elastic portion 14. The support 13 is installed in the left and right side walls (1A, 1B) of the casing 1 and pivotally supports the third roller 12 on the left and right.

  The specifications (member, structure, shape, etc.) of the elastic portion 8 are the same as those of the single roller type related to the both-bearing reel 1-1.

  The elastic portion 14 is installed between the roller support 13 and the casing 1 in order to generate a pressure contact force between the second roller 10 and the third roller 12. Unlike the elastic body of the elastic portion 8, the elastic portion 14 does not particularly have a problem with the stroke length. Therefore, the elastic portion 14 may be an elastic member such as an elastomer in addition to a coil spring, an air spring, or a plate spring. As the locking structure, for example, a structure in which the elastic body 14 is engaged with the convex portion or the concave portion provided in the left and right wall surfaces (1A, 1B) of the casing 1 and the support body 13 can be considered.

  The line guide 9 provided in the double-roller type discharge mechanism A is not particularly required because the width of the second roller 10 and the third roller 12 can be made larger than the width of the spool 3 in this embodiment. . However, depending on the layout, it may be assumed that the width of the second roller 10 and the third roller 12 is smaller than the width of the spool 3, and in that case, the line guide 9 is provided. In this case, the structure, the arrangement position, and the like are the same as those of the single roller type related to the both bearing reels 1-1.

  In the double-bearing reel having the triple roller type discharging mechanism A, the fishing line 2 wound around the spool 3 is sandwiched between the second roller 10 and the third roller 12 after passing through the level winder 5. It will be forcibly ejected out of the reel. At this time, since the feeding speed of the fishing line 2 fed from the spool 3 and the fishing line discharge speed are always the same speed, the fishing line 2 is discharged stably.

  Further, in the triple roller type, it is possible to adopt a specification in which the driving roller 6 and the second roller 10 are interlocked by a gear, a belt, or a chain. In this case, although the structure is slightly complicated, it is possible to maintain a stable fishing line discharging ability by eliminating the slip between the driving roller 6 and the second roller 10, and the power transmission efficiency is improved. This also leads to a reduction in target friction. Further, since the gear ratio can be arbitrarily set, the rotation speed (fishing line discharging speed) of the second roller 10 can be made higher than the rotation speed (fishing line feeding speed) of the driving roller 6, and the spool is taken into consideration for preventing thread breakage. The fishing line discharge speed can be set in consideration of the slip between the fishing line winding surface 31 and the driving roller 6. As a result, it is possible to provide a dual-bearing reel provided with a fishing line discharge mechanism A having a higher backlash prevention effect.

  FIG. 14 is a side view of a main part of a triple roller type dual-bearing reel 1-5 in which the driving roller 6 and the second roller 10 are interlocked by a gear. The gear-coupled triple-roller discharge mechanism A is in contact (pressure contact) with the spool fishing line winding surface 31 and rotates at the same speed as the circumferential speed of the winding surface, and the driving roller 6 A second roller 10 that rotates while driving force is transmitted through the gear, a third roller 12 that contacts (pressure contact) with the second roller 10 and rotates at the same peripheral speed, a driving roller 6 and a second roller 10. A roller support 7 that supports the two rollers 10, a support 13 that supports the third roller 12, an elastic portion 14 provided between the roller support 7 and the support 13, the support 7 and the casing 1 Driving force from the driving roller 6 to the second roller 10, the gear 15 provided coaxially with the driving roller 6, the gear 16 provided coaxially with the second roller 10, and the driving roller 6. And a gear 17 provided for transmission. It is. The gear 15, the gear 16, and the gear 17 are all provided on the left and right side plates 7A of the roller support 7 or on either side plate so as to be rotatable about an axis parallel to the spool rotation axis. 7G and the shaft support 7L are pivotally supported. The gear 17 is provided between these gears so as to mesh with the gear 15 and the gear 16. The gears 15, 16, and 17 are all made of metal or resin, and may be general gears such as spur gears and helical gears. The specifications of other parts (members, structure, shape, etc.) are basically the same as the triple roller type discharge mechanism A. However, the support 13 is installed so as to be slidable in the direction of the second roller 10 by the roller support 7 and the sliding engagement portion 7J, and the elastic portion 14 is engaged by the roller support 7 and the portion 7K. doing. Further, the drive roller 6 has a structure in which a groove is provided in the center portion and the fishing line 2 is passed through the groove. This prevents the fishing line 2 from being sandwiched between the spool winding surface 31 and the driving roller 6 and is stable by avoiding the double sandwiching state in the specification in which the discharge speed is increased with respect to the feeding speed. The fishing line 2 can be discharged.

  In the gear-linked triple-roller type fishing line discharging mechanism A, the ratio of the fishing line discharging speed and the fishing line feeding speed, the ratio of the diameter of the driving roller 6 and the second roller 10, and the ratio of the number of gear teeth (gear ratio). Can be set arbitrarily.

  In the triple roller type discharge mechanism A, a lever (not shown) is connected to the rear end portion of the roller support 7 so that the pushing portion of the lever can be operated by hand, as in the case of the dual-bearing reel 1-1. If a mechanism for separating the drive roller 6 from the spool fishing line winding surface 31 via the roller support 7 is added by pushing this, the discharge mechanism A can be artificially shut off. With this mechanism, it is possible to eliminate even a slight friction on the discharge mechanism A according to the present invention, and it is also possible to deal with the use that gives top priority to the flight distance during casting (when the clutch mechanism is released). Further, it is possible to reduce the resistance during the line winding operation (when the clutch mechanism is connected). As the structure of the lever, for example, a configuration in which the shape of the rear end portion of the roller support 7 is extended to the hand operating portion can be considered. As a means for releasing the pressure contact state between the second roller 10 and the third roller 12, for example, in the example of FIG. 13, a mechanism for pushing up the third roller 12 may be provided in the sliding engagement portion 13 </ b> D with the casing 1. Conceivable. In the example of FIG. 14, for example, when the roller support 7 is lowered until the drive roller 6 is separated from the spool winding surface 31, the support 13 interferes with the protrusions 20 provided on the left and right side surfaces of the casing 1. A method may be considered in which this acts as a stopper and the pressure contact state between the third roller 12 and the second roller 10 is released.

  In addition, the elastic part 8 of the triple-roller type discharge mechanism A is omitted as in the case of the dual-bearing reel 1-1. Instead, for example, a lever provided on the roller support 7 via a link mechanism is moved by a finger. It is good also as a structure which press-contacts the spool fishing line winding surface 31 and the drive roller 6 by pressing. As a result, only when the fishing line 2 must be forcibly discharged, the fishing line 2 can be forcibly discharged by pushing the lever at hand. The discharge mechanism is also one embodiment of the present invention.

  By providing the discharge mechanism A having the above configuration, backlash can be easily prevented without requiring a summing operation, and since it has a simple and low friction structure, it is inexpensive, has few failures, and is suitable for casting. It is possible to provide a dual-bearing reel that can secure a flight distance and that is less likely to break yarn by realizing a stable discharge speed.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea described in the claims and the specification and drawings. Is possible. Note that any shape, structure, or material not directly described in the specification and drawings is within the scope of the technical idea of the present invention as long as the effects and advantages of the present invention are exhibited.
