JP6401689B2 - Double bearing reel for fishing - Google Patents

Description

  The present invention relates to a fishing double-bearing reel, and in particular, a clutch mechanism that can be switched between an on state in which rotation is transmitted between a handle and a spool and an off state in which transmission of this rotation is interrupted. It is related with the double bearing type reel for fishing which has.

  In the conventional fishing double-bearing type reel, the rotation of the handle is transmitted to the spool via a plurality of gears and a clutch mechanism. As described in Japanese Patent Application Laid-Open No. 10-136849 (Patent Document 1), a clutch mechanism in a conventional fishing double-bearing type reel is a cylindrical pinion gear provided above a spool (handle side). Is provided. The pinion gear receives rotation from the handle.

  An engagement recess that can be engaged with a clutch pin provided on the spool shaft is formed at the spool-side end of the pinion gear. The pinion gear is configured to be movable along the rotation center of the spool shaft. When the pinion gear approaches the spool until the engagement recess of the pinion gear engages with the clutch pin (rotation transmission position), the clutch mechanism Is turned on, and the rotation of the handle can be transmitted to the spool via the pinion gear. On the other hand, when the pinion gear is separated from the spool to the position where the engagement recess of the pinion gear and the clutch pin are disengaged (rotation cutoff position), the clutch mechanism is turned off and the rotation of the handle is not transmitted to the spool. .

  The switching of the clutch mechanism from the on state to the off state is usually performed by operating a clutch operation lever provided on the reel body. Specifically, by depressing the clutch operation lever, the pinion gear can be moved from the rotation transmission position to the rotation cutoff position, and the clutch mechanism can be switched to the OFF state. On the other hand, the switching of the clutch mechanism from the off state to the on state is performed, for example, by rotating the handle. Specifically, by rotating the handle when the clutch mechanism is in the off state, the pinion gear is moved from the rotation blocking position to the rotation transmitting position as the handle rotates, so that the clutch mechanism is changed from the off state to the on state. Can be switched.

JP-A-10-136849

  As described in Patent Document 1, a pinion shaft that is separate from the spool shaft may be inserted into a through hole that penetrates the pinion gear in the axial direction. In this way, by inserting a pinion shaft separate from the spool shaft instead of the spool shaft into the through hole of the pinion gear, friction does not occur between the spool shaft and the pinion gear. Resistance can be reduced. On the other hand, since the pinion shaft is separate from the spool shaft, there is a problem that it is difficult to increase the concentricity between the pinion shaft and the spool shaft. Since the pinion gear is arranged in parallel with the pinion shaft, if the concentricity between the pinion shaft and the spool shaft is low, the concentricity between the pinion gear and the spool shaft is also low. Contact between the mating recess and the clutch pin becomes intermittent, and the rotation of the handle cannot be smoothly transmitted to the spool shaft. Such intermittent contact between the engaging recess of the pinion gear and the clutch pin also causes abnormal noise.

  Therefore, the present invention increases the concentricity of the pinion gear and the spool shaft when the clutch mechanism is on in a fishing double bearing type reel in which a pinion shaft separate from the spool shaft is inserted into the pinion gear. Is one of the purposes.

  The present invention relates to a double bearing reel for fishing. The fishing double bearing reel of the present invention includes a reel body, a handle rotatably provided on the reel body, a spool rotatably supported on the reel body via a spool shaft, and the spool shaft. An engagement portion provided in the engagement portion, an engaged portion engageable with the engagement portion, and a through-hole extending in the axial direction, the pinion gear rotating in accordance with the rotation of the handle, and the pinion gear A bearing that supports an end opposite to the spool; and a pinion shaft that is inserted into the through-hole of the pinion gear and that is arranged so that one end thereof is in contact with the upper end of the spool shaft. The pinion shaft is a separate member from the spool shaft.

  In one embodiment of the present invention, the spool shaft has a shaft main body on which the engaging portion is provided, and a small diameter portion having a smaller diameter than the shaft main body, and the pinion gear includes the engaged portion. The rotation transmission position is movable in the axial direction between a rotation transmission position that engages with the engagement portion and a rotation cutoff position where the engagement between the engaged portion and the engagement portion is released. It is configured to be supported by the small diameter portion of the spool shaft at a position.

  In one embodiment of the present invention, the pinion gear has a narrow portion having an inner diameter smaller than an inner diameter of the engaged portion, and the narrow portion is configured to be the spool when the pinion gear is in the rotation transmission position. It is provided at a position facing the small diameter portion of the shaft in the axial direction. In one embodiment of the present invention, the pinion gear is supported by the spool shaft by the inner peripheral surface of the narrow portion contacting the outer peripheral surface of the small-diameter portion of the spool shaft at the rotation transmission position. .

  According to these embodiments, when the pinion gear is in the rotation transmission position and the clutch mechanism is in the on state, the spool-side end portion of the pinion gear is supported by the small diameter portion of the spool shaft, and the pinion gear is The gear and the spool shaft can be made uniaxial. Therefore, even if the pinion gear is provided with a slight inclination with respect to the spool shaft due to the limit of processing accuracy, when the clutch mechanism is in the on state (that is, when the pinion gear is in the rotation transmission position), the pinion gear is Since the lower end of the shaft is supported by the spool shaft, this inclination can be corrected. Thus, the concentricity of the pinion gear and the spool shaft can be increased by supporting the lower end portion of the pinion gear with the spool shaft in the ON state of the clutch mechanism.

  The fishing double bearing type reel according to an embodiment of the present invention further includes an auxiliary bearing that supports an end portion of the pinion gear on the spool side. The auxiliary bearing is arranged such that the interval between the inner peripheral surface thereof and the outer peripheral surface of the pinion gear is wider than the interval between the inner peripheral surface of the narrow portion and the outer peripheral surface of the small diameter portion. The According to the embodiment, even if a force that tilts the pinion gear is applied to the pinion gear, the pinion gear is supported by the auxiliary bearing, and thus further inclination is suppressed. At this time, since the auxiliary bearing supports the pinion gear so that it can rotate and move in the axial direction, even if the pinion gear is tilted, it is possible to prevent the pinion gear from rotating and moving in the axial direction. it can.

  According to various embodiments of the present invention, in a double bearing reel for fishing in which a pinion shaft separate from the spool shaft is inserted into the pinion gear, the concentricity of the pinion gear and the spool shaft when the clutch mechanism is on Can be increased.

  Hereinafter, various embodiments of the present invention will be described with reference to the drawings as appropriate. The common components are denoted by the same reference numerals across the drawings. It should be noted that the drawings are not necessarily shown to scale for convenience.

  FIG. 1 is a plan view showing a fishing double-bearing reel according to an embodiment of the present invention. In FIG. 1, for convenience of explanation, the vicinity of the clutch mechanism of a fishing double bearing type reel is cut out. As shown in the drawing, a fishing double bearing type reel 1 according to an embodiment of the present invention includes a reel body 10 having a pair of side plates 10a, 10b, and a pair of bearings 12 on the pair of side plates 10a, 10b. The spool shaft 14 is rotatably supported via the spool shaft, the spool 16 is provided integrally with the spool shaft 14 and disposed between the pair of side plates 10a and 10b, and is rotatably supported by one side plate 10b. A handle shaft 18a, a handle 18 fixed to the end of the handle shaft 18a, and a clutch mechanism that is disposed in the side plate 10b and selectively transmits the rotation input from the handle 18 to the handle shaft 18a to the spool shaft 14. 20.

  The clutch mechanism 20 includes a substantially cylindrical pinion gear 26 disposed so as to be substantially concentric with the spool shaft 14 in the side plate 10b. In one embodiment, the end of the pinion gear 26 on the handle 18 side (upper side) is rotatable to the side plate 10b via the bearing 24, and along the rotation axis of the spool shaft 14 (ie, the spool 16). It is supported movably. Further, the end portion of the pinion gear 26 on the spool 16 side (lower side) is supported by a small diameter portion 14c of the spool shaft 14 described later when the pinion gear 26 is in the rotation transmission position. A through hole is formed in the axial direction of the pinion gear 26, and a pinion shaft 28 is inserted into the through hole. The pinion shaft 28 is provided such that one end surface thereof is in contact with the end surface on the handle 18 side of the spool shaft 14 and the other end surface thereof is in contact with the shaft cover 30. The shaft cover 30 is detachably provided on the outer wall of the side plate 10b. As described above, the movement of the pinion shaft 28 in the axial direction is restricted by the spool shaft 14 and the shaft cover 30.

  As described above, the pinion gear 26 is provided so as to be movable in a direction along the rotation axis of the spool shaft 14. The movement of the pinion gear 26 in the rotation axis direction is regulated by the end surface of the spool shaft 14 on the handle 18 side and the shaft cover 30. Specifically, the pinion gear 26 can move along the rotation axis of the spool shaft 14 between the rotation transmission position shown in FIGS. 1 and 2 and the rotation blocking position shown in FIG. The movement of the pinion gear 26 will be described later.

  A large number of teeth 32 are formed on the outer peripheral surface of the pinion gear 26. A drive gear 36 is engaged with the numerous teeth 32. The drive gear 36 is provided so as to rotate together with the handle shaft 18a. With this drive gear 36, the rotation input from the handle 18 to the handle shaft 18a can be transmitted to the pinion gear 26. Therefore, when the handle 18 is rotated in a predetermined fishing line winding direction (indicated by an arrow R in FIG. 1), the rotation generated thereby is input to the pinion gear 26 via the handle shaft 18a and the drive gear 36. Thereby, the pinion gear 26 rotates in a predetermined fishing line winding direction (indicated by an arrow X in FIG. 1).

  A large number of teeth 32 of the pinion gear 26 are fractionated in the axial direction of the pinion gear 26 by an annular groove 34 formed on the outer peripheral surface of the pinion gear 26. A clutch operation plate 38 b is engaged with the annular groove 34. The clutch operation plate 38b is biased in a direction toward the spool shaft 14 by a biasing means (not shown). The clutch operation plate 38 b is connected to a connection member 38 a extending from the clutch operation lever 38 protruding from the outer surface of the reel body 10. When the clutch operating lever 38 is pushed down, the clutch operating plate 38b moves to the right from the position shown in FIGS. 1 and 2 together with the pinion gear 26 against a biasing force of a biasing means (not shown). As a result, the pinion gear 26 is moved from the rotation transmission position shown in FIGS. 1 and 2 to the handle 18 side along the rotation axis of the spool shaft 14 by a predetermined distance (to the rotation blocking position).

  Thereafter, when the handle 18 is rotated in a predetermined fishing line winding direction, the clutch operating plate 38b together with the pinion gear 26 is moved from the rotation blocking position shown in FIG. 3 to the position shown in FIG. The spool shaft 14 is moved to the spool shaft 14 side by the predetermined distance up to (rotation transmission position). At this time, the clutch operating lever 38 is also returned from the lower pressing position in the direction perpendicular to the paper surface in FIG. 1 to the initial position before the upper pressing.

  The spool shaft 14 includes a shaft body 14b having a predetermined diameter, a clutch pin 14a provided on the shaft body 14b so as to protrude in the radial direction of the spool shaft 14, and a small diameter portion 14c having a smaller diameter than the shaft body 14b. ,have. The small diameter portion 14c is provided at the end of the shaft body 14b on the handle side. Further, the end portion of the small diameter portion 14c on the handle 18 side may be formed with an abutting portion 14d that is formed to have a smaller diameter than the small diameter portion 14c and abuts the lower end surface of the pinion shaft 28. As shown in the figure, the contact portion 14d may be tapered so that the tip thereof has a smaller diameter. Thus, by making the tip of the spool shaft 14 smaller in diameter than the shaft main body 14b, it is possible to reduce friction between the spool shaft 14 and the pinion shaft 28 when the spool 16 is freely rotated.

  At the end of the pinion gear 26 on the spool shaft 14 side, an engaged portion 26a that engages with the clutch pin 14a in the circumferential direction when the pinion gear 26 is in the rotation transmission position shown in FIG. 1 is provided. The engaged portion 26 a has an inner peripheral surface having a diameter larger than the diameter of the outer peripheral surface of the shaft body 14 b of the spool shaft 14 so as to allow the pinion gear 26 to move to the rotation transmission position. The diameter of the outer peripheral surface of the shaft main body 14b and the diameter of the inner peripheral surface of the engaged portion 26a are, for example, 0. When the pinion gear 26 is at the rotation transmission position, the gap between the small diameter portion 14c and the narrow portion 26b. It is determined to be in the range of 05 mm to 0.50 mm. Further, a pair of engaging recesses 42 is formed in the engaged portion 26a. The engaging recess 42 is formed so as to receive the clutch pin 14 a protruding in the radial direction from the spool shaft 14. Therefore, the engaged portion 26a is configured to engage with the clutch pin 14a via the engaging recess 42. As shown in FIG. 3, when the pinion gear 26 is in the rotation cutoff position, the engagement between the clutch pin 14a and the engaged portion 26a is released.

  In the illustrated embodiment, the spool shaft 14 and the pinion gear 26 are engaged with each other via the clutch pin 14 provided on the spool shaft 14 and the engagement concave portion 42 of the pinion gear 26. In addition to this, the spool shaft 14 and the pinion gear 26 can be engaged in various modes. For example, as disclosed in, for example, FIG. 7 of Japanese Patent Laid-Open No. 10-136849, a pair of mutually parallel engaging surfaces is formed on the outer peripheral surface of the shaft main body 14b of the spool shaft 14, and the pinion gear 26 A pair of mutually engaged engaged surfaces corresponding to the engaging surface is provided on the inner peripheral surface of the engaged portion 26a, and the spool shaft 14 and the pinion gear 26 are interposed via the engaging surface and the engaged surface. May be engaged. The pair of engaged surfaces of the pinion gear 26 are arranged so that the inner peripheral surface of the pinion gear 26 faces the pair of engaging surfaces formed on the spool shaft 14 when the pinion gear 26 is in the rotation transmission position. Formed.

  A narrow portion 26b having an inner diameter smaller than the inner diameter of the engaged portion 26a is provided on the handle 18 side of the engaged portion 26a of the pinion gear 26. As shown in FIG. 2, the narrow portion 26b is provided at a position facing the small diameter portion 14c of the spool shaft 14 when the pinion gear 26 is at the rotation transmission position shown in FIG. The inner diameter of the narrow portion 26b is such that the outer diameter of the small diameter portion 14c of the spool shaft 14 is allowed to allow the pinion gear 26 to move to the rotation transmission position (moving to a position where the narrow portion 26b faces the small diameter portion 14c). It is formed so as to have a diameter slightly larger than the diameter. The diameter of the outer peripheral surface of the small diameter portion 14c and the diameter of the inner peripheral surface of the narrow portion 26b are, for example, 0.01 mm to when the gap between the small diameter portion 14c and the narrow portion 26b is at the rotation transmission position of the pinion gear 26. It is determined to be in the range of 0.20 mm. Thus, when the pinion gear 26 is in the rotation transmission position, the inner peripheral surface of the narrow portion 26b abuts on the outer peripheral surface of the small diameter portion 14c of the spool shaft 14, so that the lower end side of the pinion gear 26 is supported by the spool shaft 14. can do.

  As described above, according to the above-described embodiment, when the pinion gear 26 is in the rotation transmission position, the narrow portion 26b of the pinion gear 26 is supported by the small diameter portion 14c of the spool shaft 14, and the pinion gear 26 and the The spool shaft 14 can be uniaxial. Therefore, even if the pinion gear 26 is provided with a slight inclination with respect to the spool shaft 14, the narrow portion 26b of the pinion gear 26 is moved to the small diameter portion 14c of the spool shaft 14 by moving the pinion gear 26 to the rotation transmission position. This inclination can be corrected by abutting with.

  In one embodiment of the present invention, the outer peripheral surface of the small diameter portion 14 c is formed to extend in a direction parallel to the axial direction of the spool shaft 14, and the inner peripheral surface of the narrow portion 26 b is the axial direction of the pinion gear 26. It is formed so as to extend in a direction parallel to. Thereby, even if the pinion gear 26 is provided with a slight inclination with respect to the spool shaft 14, by moving the pinion gear 26 to the rotation transmission position, the inner peripheral surface of the narrow portion 26b becomes the outer peripheral surface of the small diameter portion 14c. The posture of the pinion gear 26 can be corrected so as to face the direction parallel to the direction of the rotation. Thereby, the concentricity of the pinion gear 26 and the spool shaft 14 can be increased more reliably.

  As described above, according to the above-described embodiment of the present invention, the concentricity between the pinion gear 26 and the spool shaft 14 can be increased in the ON state of the clutch mechanism. As a result, when the clutch mechanism is in the ON state, once the rotation of the handle 18 has started, the engagement recess 42 of the pinion gear 26 and the clutch pin 14a can always be brought into contact with each other, so that the rotation of the handle 18 can be smoothly performed. It can be transmitted to the spool shaft 14. Thereby, generation | occurrence | production of the noise resulting from the intermittent contact of the engagement recessed part 42 and the clutch pin 14a can also be suppressed.

  Next, with reference to FIG.4 and FIG.5, the double bearing type reel for fishing which concerns on other embodiment of this invention is demonstrated. The double-bearing type reel for fishing according to the embodiment shown in FIGS. 4 and 5 includes the auxiliary bearing 24 ′ that supports the end of the pinion gear 26 on the spool 16 side, as shown in FIGS. It is different from the form.

  As shown in FIGS. 4 and 5, the auxiliary bearing 24 ′ is provided on the side plate 1 b at a position facing the engaged portion 26 a of the pinion gear 26. The auxiliary bearing 24 'is configured to be able to support the pinion gear 26 so as to be rotatable and movable in the axial direction thereof. The auxiliary bearing 24 'is, for example, a known ball bearing. In one embodiment of the present invention, the auxiliary bearing 24 ′ has a narrow gap between its inner peripheral surface (for example, the inner peripheral surface of the inner ring of the ball bearing) and the engaged portion 26 a of the pinion gear 26 and the small diameter portion 14 c. It is comprised so that it may become larger than the clearance gap between the parts 26b.

  According to the embodiment, for example, when a force for inclining the pinion gear 26 acts on the pinion gear 26 during winding of the fishing line, the pinion gear 26 abuts on the auxiliary bearing 24 ′, and further inclination is suppressed. . At this time, since the auxiliary bearing 24 'supports the pinion gear 26 so as to be rotatable and movable in the axial direction, even if the pinion gear 26 is tilted, the rotation of the pinion gear 26 and the movement in the axial direction are not hindered. Can be. When the pinion gear 26 is not tilted, there is a relatively large gap between the pinion gear 26 and the auxiliary bearing 24 ′. Therefore, the lower end of the pinion gear 26 is not the auxiliary bearing 24 ′ but the spool shaft 14. It is supported by the small diameter portion 14c.

  The embodiment of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.
