Description

[Detailed explanation of the idea] The present invention relates to a spinning reel for fishing.

In general, when using a spinning reel with thin thread, the center of the cross section of the thread is closer to the front side of the reel with respect to the contact area between the thread and the pick-up (full veil), as shown in Figure 1 a. In addition, there is a tendency for more thread 2 to be wound around the front portion of the spool 1, resulting in a so-called pre-winding state.

On the other hand, when using thick thread, the center of the cross section of the thread is closer to the rear of the reel with respect to the contact area between the thread and the pick-up. There is a tendency for more yarn 2 to be wound around the rear side, resulting in a so-called rear winding state.

Further, even if threads of the same thickness are used, if a heavy weight is used, the yarn tends to be in the front winding state, whereas if a light weight is used, the yarn tends to be in the back winding state.

Furthermore, the above-mentioned front-winding or back-winding state may occur depending on the accuracy of parts and assembly of the reel.

When the above-mentioned pre-winding or post-winding condition occurs, the thread collapses in the direction where less thread is wound, and when the thread is loaded, many loops of thread come off the spool at the same time. This causes the inconvenience that the reel gets tangled with other parts of the reel.

In addition, if the above-mentioned pre-winding or post-winding conditions become extreme, the thread may protrude from the spool during winding.
There is even the inconvenience of it getting tangled with other parts of the reel.

To prevent such inconvenience from occurring,
As shown in FIG. 1c, the thread 1 must be evenly wound onto the spool 2 (more specifically, in order to extend the throwing distance, it is ideal to wind it slightly afterward).

Here, even if the above-mentioned front-winding or back-winding state occurs, if the spool mounting position with respect to the spool shaft is adjusted in the axial direction, the above-mentioned front-winding or back-winding state will be resolved and the thread will be on the spool evenly ( Alternatively, it can be wound slightly later.

However, with conventional spinning reels, the spool was fixed at a fixed position on the spool shaft, so the angler himself had to adjust the line he was using so that the line would be wound evenly (or slightly later) on the spool. It is difficult to adjust the position of the spool with respect to the spool shaft depending on the type of spindle or weight.

The present invention was made to eliminate the above-mentioned conventional drawbacks, and allows the angler to easily adjust the position of the spool with respect to the spool shaft depending on the type of line and weight used, so that the line is always on the spool. To provide a spinning reel that can be wound properly.

The spinning reel according to the present invention includes a spool supported on a spool shaft so as to be rotatable relative to the spool shaft and movable in the axial direction of the spool shaft; a spool position adjustment knob that is immovably supported in the axial direction of the spool shaft; a knob-side threaded portion fixed to the spool position adjustment knob; and a knob-side threaded portion fixed to the spool and screwed to the knob-side threaded portion. and a spool-side threaded portion, and the knob-side threaded portion and the spool-side threaded portion are arranged coaxially with the spool shaft.

The present invention will be explained in more detail below based on embodiments shown in the drawings.

In this embodiment, a spool shaft 4 is supported on a main body 3 so as to be rotatable relative to the main body 3 and movable in the axial direction of the spool shaft 4.

Further, a handle shaft (not shown) is rotatably supported by the main body 3, and a handle 5 is connected to the handle shaft. moreover,
A spool cup 6 is rotatably supported on the main body 3 coaxially with the spool shaft 4. When the handle shaft is rotated via the handle 5, the spool shaft 4 reciprocates in its axial direction by a conventionally known power transmission mechanism (not shown), while the spool cup 6 It is adapted to be rotated together with a pick-up 7 rotatably supported by the cup 6.

Reference numeral 8 denotes a drag adjustment knob provided at the rear end of the main body 3, and this knob 8 constitutes a part of a conventionally known drag device (other parts of the drag device are not shown). By rotating this knob 8, the braking force of the drag device relative to the rotation of the spool shaft 4 can be adjusted.

A pin 9 is fixed to the distal end side of the spool shaft 4 in a state perpendicular to the spool shaft 4.
Reference numeral 10 denotes a spool, and a spool shaft through hole 11 passes through a boss portion 10a provided at the center of the spool 10. Further, the boss portion 1
As clearly shown in FIG. 4, a pin engaging groove 12 is provided at the rear end portion of the boss portion 10a, extending in a cross shape in the radial direction of the boss portion 10a. The spool 10 is made non-rotatable relative to the spool shaft 4 by passing the spool shaft 4 through the spool shaft through hole 11 and engaging the pin 9 in the pin engagement groove 12. The spool shaft 4 is supported by the spool shaft 4 so as to be movable in the axial direction of the spool shaft 4.

A pair of spool-side threaded bodies 13, 14 as shown in FIG. 6 are fixed to the spool 10 (these spool-side threaded bodies 13, 1
4 constitutes the spool side threaded portion in this embodiment). These spool side screw bodies 1
3 and 14 are separated from each other for assembly reasons, but functionally they constitute one female thread, and thread grooves 15 and 16 are provided on the inner peripheral surface of each.
is provided.

The tip of the spool shaft 4 forms a tapered portion 4a. Furthermore, of the spool shaft 4,
A spring engaging groove 17 is provided in the vicinity of the tapered portion 4a in the circumferential direction.

18 is a spool stop spring, and this spring 18
As is clearly shown in FIG. 5, it is made of a single linear spring material, and its both ends are parallel to each other to constitute clamping parts 18a and 18b, and the other intermediate part 18c is circular. It is curved in a shape. As shown in FIGS. 3 and 5, the spool stop spring 18 is attached to the spool shaft 4 in the axial direction of the spool shaft 4 by engaging the clamping portions 18a and 18b with the spring engaging groove 17. Mounted relatively immovably. In this attached state, the clamping parts 18a and 18b clamp the spring engaging groove 17 of the spool shaft 4 by the spring force of the spring 18.

19 is a spool position adjustment knob, and a knob side screw body 20 is fixed to this spool position adjustment knob 19 (this knob side screw body 20
constitutes the knob-side threaded portion in this embodiment). Threads 21 and 22 are provided on the outer peripheral surface of this knob-side screw body 20, and these threads 21 and 22 are screwed into thread grooves 15 and 16, respectively.

A washer 23 is held between the spool position adjustment knob 19 and the knob side screw body 20. Further, a narrow space is formed between the washer 23 and the knob-side screw body 20, and the spool stop spring 18 is accommodated in the space. As a result, the spool position adjustment knob 19
It is supported on the spool shaft 4 via a spool stop spring 18 so as to be rotatable with respect to the spool shaft 4 and immovable relative to the axial direction of the spool shaft 4 .

An articulation spring 24 is fixed to the spool 10. As clearly shown in FIG. 7, the articulation spring 24 includes an annular base 24a, two arm parts 24b cut up from the annular base 24a, and disposed at the tips of these arms 24b. It consists of a protrusion 24c.

On the inner surface of the spool position adjustment knob 19,
As shown in FIGS. 3 and 9, an appropriate number of joint recesses 25 are provided on the circumference concentric with the spool shaft 4, and these recesses 25 are adjusted according to the rotational position of the spool position adjustment knob 19. The two protrusions 24 of the articulation spring 24 are inserted into any two of the articulation recesses 25.
c are adapted to be engaged with each other.

A spool removal button 26 is located in the center of the spool position adjustment knob 19, and a spool removal button 26 is located at the center of the spool position adjustment knob 19.
It is movable in the axial direction of the spool position adjustment knob 19, and is fitted into the spool position adjustment knob 19 so that it cannot fall off. The distal end side of the spool removal button 26 forms a tapered part 26a, as clearly shown in FIG. A button spring 30 is interposed between the spool removal button 26 and the washer 23, and this spring 30 connects the spool removal button 26 to the spool stop spring 18.
It is biased in the direction of separating it from the

On the surface of the spool position adjustment knob 19,
A scale plate 27 is attached, and this scale plate 2
On the surface of 7, there is a scale 2 as shown in FIG.
8 is attached. Furthermore, a scale indicating mark 29 is provided at the front end of the spool 10.

Next, the operation of this embodiment will be explained.

When the spool position adjustment knob 19 is rotated, the knob side screw body 2 fixed to this knob 19 is rotated.
0 also rotates integrally with the same knob 19. Then, since the spool position adjustment knob 19 and the knob-side screw body 20 are prevented from moving in the axial direction with respect to the spool shaft 4 by the spool stop spring 18, the spool-side screw bodies 13 and 14, and by extension the spool 10, It moves in the axial direction relative to the spool shaft 4.

Therefore, by rotating the spool position adjustment knob 19, the angler himself can very easily and freely adjust the position of the spool 10 with respect to the spool shaft 4 so that the line is properly wound around the spool 10. .

Further, in this embodiment, when the spool position adjustment knob 19 is rotated, the protrusions 24c of the articulation spring 24 are sequentially engaged and disengaged from an appropriate number of articulation recesses 25 provided on the knob 19, so that knob 19
rotates jointly. Therefore, once the spool position adjustment knob 19 is set at a position where the protrusion 24c engages with a certain articulation recess 25, the knob 19 will not naturally move from that position.

In addition, in this embodiment, since the scale 28 and the scale indication mark 29 are provided, which scale 28 should be assigned to the scale indication mark 29 for each predetermined combination of various thread thicknesses and weights. If you check whether it is appropriate to match the scale to 2, then you can adjust the scale to 2 without actually winding the thread.
8 to the scale indication mark 29, the position of the spool 10 relative to the spool shaft 4 can be immediately adjusted to an appropriate position.

Furthermore, in this embodiment, when it is desired to remove the spool 10 from the spool shaft 4, by pressing the spool removal button 26 against the button spring 30, the spool removal button 26 is pressed as shown by the dashed line in FIG. The tapered part 26a of 26 is connected to the spool stopper spring 18.
The clamping part 1 is inserted deeper between the clamping parts 18a and 18b, and the clamping parts 18a and 18b are pushed apart.
8a, 18b and the spring engagement groove 17,
By pulling the spool 10 in this state, the spool 10 can be easily pulled out from the spool shaft 4.

If you want to attach the spool 10 to the spool shaft 4 again, you can fit the pin 9 into the pin engagement groove 12 and pass the spool shaft 4 through the spool shaft through hole 11. The tapered part 4a is the clamping part 18a, 1 of the spool stop spring 18.
The spool 10 can be attached to the spool shaft 4 very easily since the holding portions 18a and 18b are engaged with the spring engagement groove 17 by spreading the space between the spools 8b and 8b apart.

In the above embodiment, a thread is provided on the spool position adjustment knob side and a female thread is provided on the spool side, but it is also possible to provide a female thread on the spool position adjustment knob side and a thread on the spool side. Needless to say.

As described above, the spinning reel according to the present invention allows anglers to easily adjust the position of the spool with respect to the spool shaft depending on the type of line and weight used, so that the line is always properly wound around the spool. It is possible to obtain excellent effects such as:
