[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spinning reel having a rotary frame positioned in front of a reel body and provided with a stopper mechanism for preventing the rotary frame from reversing in the line feeding direction.

[0002]

2. Description of the Related Art A rear open type recessed space is formed at the rear portion of a rotating frame, and a minute gap portion is formed by making the inner peripheral wall of the recessed space close to the reel body (actual flat 2). -44976).

[0003]

As described above, the minute gap prevents the sand or the like from entering the recessed space and prevents the sand or the like from being caught in the rotating part. Although the rotation operation of the rotating frame is smoothly performed, the formation of the minute gap cannot completely prevent the intrusion of sand or the like, and instead, it may bite into the minute gap.
The purpose of the present invention is to construct a mechanism with high sealing properties between the reel body and the rotating frame while taking into account the installation position of a stopper mechanism that prevents the rotation of the rotating frame in the yarn feeding direction, In that the rotation frame can be smoothly rotated over a range of

[0004]

The present invention is characterized in that a rearwardly open recessed space is formed on the rear surface of a rotating frame located in front of a reel body, and that a front wall of the recessed space is formed. Erect a first annular wall toward the rear,
A stopper mechanism locking tooth is formed on the inner peripheral surface of the annular wall to prevent the rotating frame from reversing in the line feeding direction, and between the inner peripheral wall of the recessed space and the first annular wall. A second annular wall protrudes from the reel body in a state where the reel enters, and an intrusion suppressing member is provided between the first annular wall and the second annular wall or between the inner peripheral wall and the first annular wall. The effect is as follows.

[0005]

In other words, a labyrinth-shaped sealing space is formed by the inner peripheral wall of the recessed space and the first and second annular walls.
For example, even if sand or the like intrudes between the inner peripheral wall and the second annular wall, the invading sand or the like is reduced by a labyrinth-shaped bend corresponding to the tip of the second annular wall to reduce its moving force and reduce the moving force. The movement of the lost sand or the like can be prevented by the intrusion suppressing member, and it can be completely prevented from entering the recessed space.
Therefore, the sand or the like is blocked before reaching the stopper mechanism locking teeth formed on the inner peripheral surface of the first annular wall by the intrusion suppressing member, so that the influence on the operation of the stopper mechanism is small.

[0006]

The second annular wall extends from the front wall of the concave space inside the inner peripheral wall of the concave space, and the locking teeth for the stopper mechanism are provided on the inner peripheral surface of the extended second annular wall. By forming, the labyrinth-like space firstly exerts the function of preventing intrusion of sand and the like entering the recessed space, and subsequently, the intrusion of the still invading sand and the like by the intrusion suppressing member. Thus, it is possible to construct a two-stage seal structure for preventing the occurrence of sand, and to easily prevent the operation of the stopper mechanism using the locking teeth from being affected by sand or the like being intermingled.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a spool shaft 3 extends from a reel body 2 supporting a handle 1 and a spool 4 is loosely fitted on the spool shaft 3. The cylindrical shaft 6 is loosely fitted to the base end of the spool shaft 3, and the rotary frame 7 is mounted on the cylindrical shaft 6 so as to be integrally rotatable. A pinion gear 9 is formed in a portion of the cylinder shaft 6 located inside the reel body 2, and the thread winding operation of the rotary frame 4 by operating the handle 1 is performed by engaging the pinion gear 9 with the main gear 10 mounted on the handle shaft 5. . The spool 4 is reciprocally driven at a constant stroke by connecting the spool shaft 3 to the slider that reciprocates along the spiral shaft 8 with the rotation of the spiral shaft 8 that rotates by receiving power transmission from the main gear 10. The oscillating mechanism A is formed to constitute a spinning reel.

Next, the stopper mechanism B of the rotating frame 7 will be described. As shown in FIGS. 1, 2 (a), (b), and 3, a rear open-type recessed space 7 </ b> A recessed forward is formed on the rear surface of the rotating frame 7, and the recessed space 7 </ b> A A first annular wall 22, which will be described later, is formed to face backward from the front wall 7B. A ratchet tooth 11 serving as a locking tooth for a stopper mechanism is formed on the inner peripheral wall of the first annular wall 22, and a ratchet pawl 12 engaging with the ratchet tooth 11 forms a stopper mechanism B. Body 2
It is configured to be pivotable about a horizontal axis perpendicular to the spool axis. On the other hand, in the cylinder body 6 in the reel body 2,
The rotary cam body 13 is loosely fitted and the rotary cam body 1
A rotary driving body 14 is attached to the cylindrical shaft 6 so as to be rotatable integrally with the cylindrical shaft 6, and the rotary cam body 13 and the rotary driving body 14 are configured to be integrally rotatable by a friction mechanism (not shown). A cam surface 13A projecting rearward is formed on the rear surface of the rotary cam body 13, and the follower arm 1 contacting the cam surface 13A.
2A is extended from the boss of the ratchet claw 12. With this configuration, when the cylindrical shaft 6 rotates together with the rotary frame 7, the rotary driving body 14 rotates, and the rotary cam body 13 is rotated by the friction mechanism and stops at a constant phase against the stopper. If this rotation direction is the normal rotation direction in which the yarn is wound, the cam surface 13A rotates the following arm 12A backward to separate the ratchet pawl 12 from the ratchet teeth 11. When the rotating frame 7 is rotated in the reverse rotation direction in which the yarn is fed, the rotary driving body 14 rotates, and the rotating cam body 13 is rotated by the friction mechanism and stops at a different fixed phase against the stopper. Then, the cam surface 13A separates from the following arm 12A, and the ratchet pawl 12
1 can be occluded. From the above, ratchet claw 1
The state where 2 engages with the ratchet gear 11 is referred to as the engaged state of the stopper mechanism B, and the state where the ratchet pawl 12 does not engage with the ratchet gear 11 is referred to as the cut state of the stopper mechanism B.

An operation structure for switching the stopper mechanism B between the on state and the off state will be described. As shown in FIG. 3, a stopper switching knob 15 protruding rearward from the rear end of the reel body 2 is provided, and an operating shaft 16 linked to the stopper switching knob 15 is passed through the reel body 2 back and forth. And the tip of the operating shaft 16 is extended to near the ratchet pawl 12, and a switching cam 17 is attached to the extended end.
Is formed, and the non-operating end of the ratchet pawl 12 is pressed by the switching cam 17 to switch the ratchet pawl 12 to the non-occlusal posture. Therefore, when the stopper switching knob 15 is operated to one side, the switching cam 17 acts on the ratchet pawl 12 to switch to the non-occlusal posture, and the stopper is rotatable in any of the line feeding direction and the line winding direction of the rotary frame 7. When the cutting state of the mechanism B and the stopper switching knob 15 are operated to the other side, the switching cam 17 is separated from the ratchet pawl 12 to allow the ratchet pawl 12 to switch to the occlusal posture, and the rotation of the rotary frame 7 in the line let-out direction. Can be switched to the engagement state of the stopper mechanism B which prevents rotation in the line winding direction. A half-moon-shaped portion 16A is located at an intermediate position of the operation shaft 16.
And a stopper 18 is provided at a position corresponding to the half-moon-shaped portion 16A to constitute a positioning mechanism for maintaining the stopper knob 15 at the operation position when operated. The receiving piece 18 has a positioning function of entering the recessed portion of the semilunar portion 16A and restricting the movement of the operation shaft 16 in the axial direction. Next, the leg 2A of the reel body 2 will be described. As shown in FIG. 4, a concave portion is formed on the upper surface of the leg portion 2A, a pad 19 is mounted in the concave portion, a rod portion 19A is attached to the bottom surface of the pad 19, and the rod portion 19A is connected to a pillar. It hangs down in the state located in 2B. A screw portion is formed at the lower end of the rod portion 19A, and an adjusting disk 20 screwed to the screw portion is fitted into the pillar 2B. This adjusting disc 20
Is rotated about the axis of the rod portion 19A, thereby moving the pad 19 up and down integrally with the rod portion 19A, stabilizing the mounting state of the rod to the reel sheet, and suppressing rattling.

Next, the structure of the rotary frame 7 in the recessed space 7A will be described. As shown in FIG. 1, between the first annular wall 22 protruding rearward from the front wall 7B of the recessed space 7A and the inner peripheral wall 7C of the recessed space 7A, the second annular wall 22 is disposed forwardly of the front wall of the reel body 2. An annular wall 21 is protruded, and the second annular wall 21 is positioned between the two 22 and 7C to form a labyrinth-shaped seal structure. A ring-shaped member 23 made of soft rubber and having a substantially pentagonal cross section is mounted between the first annular wall 22 and the second annular wall 21 as an intrusion suppressing member. By mounting the intrusion suppressing member 23, intrusion of sand or the like into the cylindrical shaft 6 side in the recessed space is prevented, and rattling of the rotating frame 7 is suppressed. Further, an annular ridge 21a is formed at the end of the second annular wall 21 so as to protrude in the radial direction, so as to intrude into sand or the like entering between the second annular wall 21 and the inner peripheral wall 7C of the recessed space 7A. A configuration is adopted in which resistance is given and the sealing effect is enhanced in cooperation with the sealing member 23.

Another Embodiment Next, another structure of the intrusion suppressing member 23 will be described. As shown in FIG. 5, the first annular wall 22 and the second annular wall 2
As the intrusion suppressing member 23 to be inserted between the two, a commonly used bearing such as a ball bearing with a seal may be used. As the bearing, a roller bearing as a rolling type or a sliding bearing made of phosphor bronze or resin may be used. Another structure of the stopper mechanism B will be described. As shown in FIG. 5 and FIG.
The support shaft 24 is erected toward the recessed space 7A of
A ratchet pawl 26 is attached to the support shaft 24 so as to be able to swing around a longitudinal axis. The ratchet teeth 11 are formed on the inner peripheral surface of the first annular wall 22. As a mechanism that acts on the ratchet pawl 26 to switch its posture, a spacer 25 that rotates integrally with the cylinder shaft 6 is fitted onto the cylinder shaft 6, and the rotating cam body 13 is loosely fitted on the spacer 25. The base end of a linking spring 27 linked to the cam body 13 is wound around the spacer 25 with a slight pressing force. With this configuration, as described in the previous embodiment, it is possible to switch between the state in which the ratchet claw 26 can bite and the state in which the ratchet claw 26 is separated from the ratchet teeth 11. An operation shaft 16 and a switching cam 17 connected to the stopper knob 15 are provided so as to forcibly act on the ratchet pawl 26 and forcibly maintain the ratchet pawl 26 in a state of being separated from the ratchet teeth 11. An intrusion suppressing member 23 may be mounted between the second annular wall 21 and the inner peripheral wall 7B of the recessed space 7A.
