Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing reel reversing prevention device incorporating a one-way bearing.

[0002]

2. Description of the Related Art Conventionally, in a fishing reel incorporating a one-way bearing, in order to prevent reverse rotation and switch to a rotation-free state, a hook is provided on the outer periphery or a side surface of the one-way bearing and engaged with the catch wheel. The stop pawl can be configured to engage or disengage the ratchet wheel and the locking pawl with a bearing or the like on the reel body, or the one-way bearing reverse rotation roller retainer can be rotated to position the reverse rotation roller retainer. By changing the position, the reverse rotation preventing roller is moved to a narrow portion (reverse rotation preventing position) of a wedge-shaped clearance portion of the inner diameter of the outer ring and to a wide clearance portion (rotation free position).

[0003]

In the above-described mechanism using the locking pawl, when the reverse rotation prevention switching is performed, the play within the division angle of the number of teeth of the ratchet wheel is required until the ratchet and the locking pawl fall into the reverse rotation preventing position. Is the switching operation delay, and during the reverse rotation prevention operation, from the forward rotation state until the reverse rotation prevention is applied, the rattling of the ratchet wheel and the locking claw,
It is inevitable that an operation delay occurs due to play due to a gap or the like. Also, when the reel is rotating forward in the free state, even if you try to switch to the reverse rotation prevention state, the teeth of the reverse stop pawl are usually made higher on the reverse stop side and lower on the forward side. Since the locking claw is jumped off by the ratchet wheel, it jumps over the teeth on the normal rotation side, and as a result, the timing until the engagement is shifted, that is, there is a disadvantage that the switching is delayed.

In the method of moving the position of the retainer described later, the structure of the one-way bearing itself becomes complicated, and it is difficult to configure the one-way bearing as one completed part. There were inconveniences such as having to assemble each part of the one-way bearing.

[0005]

In order to solve the above-mentioned problems, the present invention is configured to rotatably be supported on a reel body and fitted to a rotary drive shaft or a rotary drive shaft which is interlocked with handle rotation. In a fishing reel in which a one-way bearing is engaged with a shaft cylinder to prevent reverse rotation, a sleeve having a chamfered or tapered introduction portion on an end surface with a diameter larger than the diameter of a rotary drive shaft engaged with the one-way bearing. By fitting the body from the inner diameter openings on both sides of the one-way bearing and engaging or disengaging the reverse rotation roller in the one-way bearing from both sides,
The reverse rotation preventing roller can be switched and held in a separated or engaged state with respect to the rotation drive shaft or the shaft cylinder, respectively.

[0006]

The reverse rotation switching of the present invention is performed by a simple operation of separating or engaging the reverse rotation preventing roller in the one-way bearing between the one-way bearing and the rotary drive shaft from the rotary drive shaft. The on / off switching of the prevention can be performed smoothly with little operation delay.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway side view showing an example in which a reverse rotation preventing device according to the present invention is applied to a spinning reel.

In FIG. 1, reference numeral 1 denotes a reel body. Here, a schematic rotation drive system will be described. By rotating the handle 2, the drive gear 4 fitted and fixed to the handle shaft 3, and subsequently fitted to the spool shaft 5 offset from the plane orthogonal to the center axis of the drive gear 4 and fitted by the bearing 6 A rotatable pinion gear 7 rotates in conjunction therewith, and a rotor 10 for winding a thread around a spool 9 is mounted on the pinion gear shaft cylinder 8.

In order to prevent reverse rotation of the drive shaft, that is, to prevent reverse rotation of the reel, a storage portion 12 for a one-way bearing 11 is provided around the pinion gear shaft tube 8 of the main body 1, and the one-way bearing 11 is attached to the pinion gear shaft tube 8. The one-way bearing 11 is fitted, and the concave key groove 14 of the one-way bearing 11 is fixed to a convex key 15 formed in the storage portion 12 and parallel to the axial direction. The sleeve body 17, 17 ′ provided with the tapered introduction portions 16, 16 ′ can be disengaged from the end faces 19, 19 ′ of the reverse rotation roller 18 in the one-way bearing 11. The springs 20 and 20 ′ are fitted between the sleeve bodies 17 and 17 ′ and the one-way bearing 11. Therefore, the front and rear sleeve bodies 17, 17 'are
0 'urges the storage unit 12 toward the front and rear walls, respectively. The rear sleeve body 17 ′ is in contact with the front end face 23 of the operation bar 22 inserted through the rear wall hole 21 of the storage section 12, and the rear end face 24 of the operation bar 22 is a cam portion of the switching lever 25. 26 can be disengaged.

Next, a first operation of the embodiment will be described. First, when the switching lever 25 is operated to the position shown in FIG. 2A, the operation bar 22 separates from the cam portion 26 as shown in FIG. 1, so that the operation bar 22 is moved backward by the spring 20 'via the sleeve body 17'. It is urged to. Accordingly, the taper introduction portions 16 and 16 ′ of the sleeve members 17 and 17 ′ are separated from the end faces 19 and 19 ′ of the reverse rotation roller 18, and the reverse rotation roller 18 is moved toward the narrow portion 28 of the wedge-shaped gap 27 of the one-way bearing 11. Spring 29 (reverse rotation direction)
Urged by the engagement portion 13 of the rotary drive shaft.
Therefore, when the rotation drive shaft is rotating forward, the reverse rotation preventing roller 18 rolls in the direction from the narrow gap 28 to the wide gap 30 so that the forward rotation is not hindered. At the time of reverse rotation, the reverse rotation preventing roller 18 rolls from the wide gap 30 toward the narrow gap 28,
The reverse rotation is stopped by being sandwiched between the narrow gap 28 and the rotary drive shaft 13. That is, the first operation state is a reverse rotation prevention state.

Next, the second operation will be described. First, when the switching lever 25 is switched to the position b in FIG. 2, the operation bar 22 is pushed forward by the cam portion 26 as shown in FIG. 3, and the front end face 23 of the operation bar 22 causes the rear sleeve body 17 ′, Next, it is pressed against the one-way bearing 11 and then the front sleeve body 17. Therefore, the sleeve body 1
The taper introduction portions 16 and 16 'of 7 and 17' engage the end faces 19 and 19 'of the reverse rotation roller 18 from both sides, and the taper introduction portions 16 and 16' allow the reverse rotation roller 18 to engage with the rotation drive shaft. Since it is spaced apart from the outside in the radial direction, it is not affected by the one-way bearing 11, so that the rotary drive shaft is free. Therefore, the second operation state is a state where both forward and reverse rotations are free.

By switching the switching lever 25 as described above, the first operation and the second operation can be switched and held.

FIG. 7 shows a second embodiment in which a drive gear shaft of a spinning reel is provided with a reverse rotation preventing device according to the present invention.
The difference from the first embodiment is that the operation bar 22 is omitted, and the cam portion 26 of the switching lever 25 is directly engaged with the one-way bearing. The other mechanisms are the same as those of the first embodiment. It is a thing and can obtain the same effect.

FIG. 8 shows a third embodiment of the present invention in which the dual-bearing reel is provided with the reverse rotation preventing device of the present invention. In this embodiment, the same mechanism is arranged on the drive gear shaft as in the second embodiment, and the same effects can be obtained.

In the description of the present embodiment, the shaft engaged with the one-way bearing is a pinion gear barrel, but the same applies to the engagement with the barrel fitted to the pinion gear barrel.

As described above, the present invention can be similarly applied to various fishing reels, for example, the above-described spinning reel, dual bearing reel, single bearing reel, closed face reel and the like.

[0017]

As described above, switching between reverse rotation prevention and rotation-free switching is performed by directly disengaging and engaging the reverse rotation preventing roller in the one-way bearing and the engaged rotary drive shaft. As a result, there is little waste in operation, a reliable function with little operation delay is obtained, and the structure is simple, so that a compact design can be achieved.
