Description

[Detailed description of the invention] (Technical field) The present invention relates to a spinning reel for fishing.
In particular, it relates to spinning reels with improved drag knobs.

(Prior art) In a conventional spinning reel with a rear drag method (a method in which the drag knob is provided at the rear of the body), salt water passes through the gap between the cap-shaped drag knob and the body and reaches the adjustment member (the drag knob). It is provided to adjust the relationship between the rotational position and the drag force at that time, and it enters the threaded part between the drag knob (fixed to the drag knob so that the rotation angle with respect to the knob can be adjusted) and the body. death,
There was a drawback in that the liquid became hard at the threaded portion, making it impossible to rotate the adjustment member and thus the drag knob with respect to the body.

Incidentally, the intrusion of salt water into the threaded part between the adjustment member and the body as described above can be prevented to some extent by applying oil to the threaded part, but in that case, the adjustment member There is a possibility that oil may get on the brake member of a nearby drag device, causing the brake member to slip, causing a new problem that the drag device will no longer be able to perform its original function.

(Purpose of the invention) The present invention was made in order to eliminate the above-mentioned drawbacks of the conventional technology. The aim is to provide a spinning reel that is not.

(Summary of the invention) The spinning reel according to the invention reduces the thickness of the side wall near the open end of the drag knob, and closely fits the thinned side wall near the open end into the body. This achieves the above objectives.

〔Example〕

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

1 to 5 show an embodiment of the present invention. In this embodiment, a handle shaft 3 is rotatably supported on the body 1 via a bearing 2 (see FIG. 2), and a handle 4 (see FIG. 1) is attached to one end of the handle shaft 3. ) are combined. A face gear 5 and a spur gear 6 are fixed to the handle shaft 3.

A cylindrical spool cup shaft 8 is rotatably supported on the body 1 via a bearing 7 (see FIG. 1), and a spool cup 9 is provided at the front end of the spool cup shaft 8. is fixed.
A pickup 10 is rotatably supported on this spool cup 9. Further, a small gear 11 that meshes with the face gear 5 is integrally formed at the rear end of the spool cup shaft 8. A ratchet gear 12 is fixed to the spool cup shaft 8 adjacent to a small gear 11, and this ratchet gear 12 is connected to the body 1.
The spool cup 9 is prevented from reversing by being engaged with a ratchet pawl 13 that is rotatably supported by the spool cup 9. (biased toward gear 12).

The spool cup shaft 8 includes a spool shaft 1
4 is penetrated, and this spool shaft 14 is rotatable independently with respect to both the body 1 and the spool cup shaft 8, and
It is movable in the axial direction relative to the cup shaft 8. A spool 15 is fixed near the front end of the spool shaft 14. In this embodiment, the spool 15 is completely fixed to the spool shaft 14;
The spool 15 is attached to the spool shaft 14 so that the position of the spool 15 relative to the spool shaft 14 can be adjusted.
It may also be semi-fixed.

A spur gear 17 that meshes with the spur gear 6 is rotatably supported on the body 1, and an eccentric pin 18 is fixed to the side surface of the gear 17. On the other hand, a crank 19 is supported on the spool shaft 14 so as to be non-rotatable and non-movable in the axial direction, and the eccentric pin 18 is fitted into a groove 20 provided in the crank 19 . put it here,
The eccentric pin 18, crank 19 and groove 20
constitutes a crank mechanism that converts the rotational motion of the spur gear 17 into linear reciprocating motion of the spool shaft 19.

As shown in FIG. 2, the rear end of the body 1 has a cylindrical shape extending parallel to the spool shaft 14, and a female thread 21 is provided on the inner peripheral surface of the rear end of the body 1. It is provided. A male screw 22a provided on the outer periphery of the adjustment member 22 is screwed into the female screw 21. As clearly shown in FIG. 4, an appropriate number of teeth 23 are provided on the outer periphery of the rear end of the adjusting member 22. As shown in FIG.

On the other hand, 24 is a drag knob made of relatively soft synthetic resin such as nylon, and is approximately cap-shaped. A tooth-like recess 25 corresponding to the tooth 23 is provided at the inner bottom of the drag knob 24, and the tooth-like recess 25 is fitted into the tooth 23. As a result, the adjustment member 22 and the drag knob 24 are made relatively unrotatable. Further, the drag knob 24 is prevented from coming off from the adjustment member 22 by a screw 26 screwed into a female thread 22b provided at the center of the adjustment member 22.

The wall thickness of the side wall near the open end of the drag knob 24 is made thin (hereinafter, this thin wall portion of the side wall will be referred to as a thin wall portion 24a). Also,
A plurality of grooves 27 are provided in a direction parallel to the spool shaft 14 at appropriate angular intervals on the inner peripheral surface of the portion of the drag knob 24 other than the thin wall portion 24a (see FIGS. 2 and 4). ). Further, on the outer peripheral surface of the drag knob 24, scales 28 are provided at angular intervals corresponding to the installation intervals of the grooves 27.

A flange portion 2 is provided near the rear end of the body 1.
9 is provided on this flange portion 29,
The thin wall portion 24a of the drag knob 24 is tightly fitted. Further, as shown in FIGS. 2 and 3, in a portion of the body 1 near the flange portion 29, a leaf spring mounting hole 30 is formed in a direction parallel to the spool shaft 14 on the inner side of the outer circumference of the flange portion 29. It is set in. Reference numeral 31 denotes an articulating leaf spring, and one end of the leaf spring 31 is inserted into the mounting hole 30 and fixed to the body 1 with a screw 32. A protrusion 31 is provided at the other end of the leaf spring 31.
a is provided, and this protrusion 31a is adapted to be engaged with and disengaged from the groove 27 of the drag knob 24.

As clearly shown in FIG. 3, the rear end portion of the spool shaft 14 is provided with a flat portion 14a, thereby making the cross section non-circular. At the rear end of this spool shaft 14, an appropriate number of approximately annular and plate-shaped spool shaft side brake members 33 are provided.
It is fitted so that it cannot rotate relative to the spool shaft 14 but is movable in the axial direction. On the other hand, on the inner circumferential surface near the rear end of the body 1, as clearly shown in FIG.
These grooves 34 are provided with protrusions 3 provided on the outer periphery of a suitable number of generally annular and plate-shaped body-side brake members 35.
5a is fitted. As a result, the body-side brake member 35 cannot rotate relative to the body 1. In addition, here, the spool shaft side brake member 33 and the body side brake member 35
are adjacent to each other alternately. In this embodiment, the spool shaft side brake member 33 and the body side brake member 35 are directly adjacent to each other, but in order to increase the frictional force generated between both brake members 33, 35, both brake members 33, Another material having a large coefficient of friction may be interposed between 35 and 35.

Each of the brake members 33 and 35 and the adjustment member 22
A compression coil spring 36 and a spring receiver 37 are interposed between the body 1 and the body 1. There is.

Next, the operation of this embodiment will be explained.

When the handle shaft 3 is rotated by turning the handle 4, the spur gear 17 is also rotated via the spur gear 6, and the rotational movement of the spur gear 17 is caused by the eccentric pin 18,
The crank mechanism composed of the crank 19 and the groove 20 converts the spool shaft 14 into linear reciprocating motion. Therefore, the spool shaft 14 reciprocates in the axial direction together with the spool 15.

At the same time, the rotation of the handle shaft 3 also rotates the spool cup 9 via the face gear 5, small gear 11, and spool cup shaft 8, so that the spool cup 9 is guided by the pick-up 10 attached to the cup 9. Then, the thread is wound onto the spool 15.

Also, each brake member 33,
35 are pressed against each other, a frictional force is generated between each brake member 33 and 35. For this reason, normally the spool shaft 14 and, by extension, the spool 15 cannot rotate, but when a load above a certain level is applied to the thread wound around the spool 15, the spool shaft 14 moves along with the spool 15 between the brake members 33 and 35. It begins to rotate against the frictional force.

Then, when the drag knob 24 is rotated, the adjustment member 22 also rotates integrally with the knob 24, the distance between the adjustment member 22 and each brake member 33, 35 changes, and the spring 36 causes each brake member 33, 35 to rotate.
The pressing force changes, and each brake member 33, 3
The frictional force between the two also changes. Therefore, by rotating the drag knob 24, the load at which the spool 15 starts rotating, that is, the drag force, can be adjusted. Note that even if the spring 36 is not provided and each brake member 33, 35 is directly pressed by the adjustment member 22, the same adjustment can be performed.

Furthermore, when the drag knob 24 is rotated as described above, the protrusions 31a of the leaf spring 31 are sequentially engaged and disengaged from the groove 27 provided in the knob 24, so that the drag knob 24 rotates in an articulated manner.

Now, in this reel, the thin wall portion 24a of the drag knob 24 is given sufficient elasticity by being thin, so that the thin wall portion 24a is fitted into the flange portion 29 of the body 1 sufficiently closely. Therefore, the thin wall portion 24a and the flange portion 29 are sealed extremely well. Therefore, the tide water
Water enters the threaded joint between the adjustment member 22 and the body 1 through the space between the drag knob 24 and the body 1, and solidifies in the threaded joint, causing the adjustment member 22 and, by extension, the drag knob 24 to become immobile. disappears.

Further, since the thin wall portion 24a is highly elastic as described above, even if the sealing performance between the thin wall portion 24a and the flange portion 29 is improved, there is no large resistance to the rotation of the drag knob 24. , the drag knob 24 can be rotated smoothly.

The relationship between the rotational position of the drag knob 24 and the drag force at that time can be easily adjusted as follows. That is, after removing the screw 26 from the adjusting member 22, the toothed recess 25 of the drag knob 24 and the tooth 23 of the adjusting member 22 are unfitted, and the screw 26 is moved in either direction relative to the previously fitted position. By fitting the toothed recess 25 and the teeth 23 again at the position rotated by the required amount and adjusting the rotation angle of the drag knob 24 with respect to the adjustment member 22, the rotational position of the drag knob 24 and the rotational position at that time can be changed. The relationship with drag force can be easily adjusted.

Here, this reel has a mechanism for sealing between the drag knob 24 and the body 1 by fitting the thin wall portion 24a into the flange portion 29 as described above. , there is no problem in the above-mentioned drag force adjustment work.

(Effect of the invention) As described above, the spinning reel according to the invention seals between the drag knob and the body, and the tide water passes through the gap between the drag knob and the body to the threaded connection between the adjustment member and the body. This prevents water from entering the body, unlike in the conventional case where water becomes hard at the threaded joint and makes it impossible to rotate the adjustment member and, by extension, the drag knob with respect to the body. This provides an excellent effect in that smooth rotation of the knob is not hindered.
