Description

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

Specifically, the bundle includes a bundle shaft having a master gear, a cylindrical shaft having a pinion meshing with the master gear and supporting a rotating frame, and a spool shaft movably supported by the cylindrical shaft and supporting a spool. The present invention relates to a spinning reel in which a rotating frame is rotated while reciprocating the spool via a spool shaft by rotation of the shaft, as if fishing line is wound onto the spool.

! Generally, in this type of spinning reel, the spool shaft is linked to the bundle shaft by a rotation to reciprocating motion conversion mechanism having an eccentric cam.In other words, the bundle shaft has an eccentric cam that is eccentric by a predetermined amount with respect to its axis. At the same time, an interlocking plate is formed with a circular hole that fits the eccentric cam, and the end portion of the interlocking plate is pivotally connected to the spool shaft, and the circular hole is fitted onto the eccentric cam, and the The spool shaft is configured to reciprocate as the bundle shaft rotates, but in such a structure, when the spool shaft reciprocates, the speed of movement differs between the ends of the reciprocating motion and the intermediate portion. When the fishing line is wound around the spool by rotating the rotating frame, the pitch changes, making it impossible to wind the fishing line parallel to the spool.In other words, a large amount of fishing line is wound on both sides of the winding section of the spool, resulting in a so-called problem. There was a problem in that the fishing line on the spool was wound irregularly.

Therefore, the spool shaft is reciprocated by a traverse mechanism, so that the fishing line is wound parallel to the spool.

This traverse mechanism forms a reciprocating spiral groove on the spool shaft, and a cylindrical slider that rotates in conjunction with the bundle shaft is inserted into the spool shaft, and enters the spiral groove from the slider. However, since the spool shaft requires strength and corrosion resistance, it is usually made of stainless steel. It is very difficult to form a spiral groove like this, and the workability is poor, resulting in problems such as increased manufacturing costs.

In addition, conventional spinning reels are constructed so that the spool makes one reciprocation for each rotation of the bundle shaft, and the rotating frame rotates three to four times.When winding the fishing line onto the spool, the fishing line Due to the rotation of the rotating frame, the fishing line is wound spirally on the spool at a large pitch, and this winding creates a large gap between the fishing lines, resulting in a very small amount of fishing line being wound on the spool. Ta.

The present invention was devised in view of the above-mentioned problems, and its purpose is to be able to wind the fishing line parallel to the spool without the need to form a reciprocating helical groove on the spool shaft. To provide a spinning reel that is extremely simple to manufacture, can reduce costs, and can also wind fishing line on a spool without any gaps and increase the amount of fishing line wound. .

Embodiments of the present invention will be described below based on drawing □.

In the figure, reference numeral 1 denotes a reel body having legs 2 for attaching to a fishing rod, and a bundle shaft 3 equipped with a master gear 4 and a bundle 5 is freely rotatable in a direction transverse to the body 1 within this reel body 1. A cylindrical shaft 6 extending in the longitudinal direction of the reel is rotatably supported on the reel body 1, and a rotating frame 7 is attached to the tip of the cylindrical shaft 6 that projects forward from the reel body 1. A pinion 8 that meshes with the master gear 4 is formed at the inner end of the cylindrical shaft 6, and a spool shaft 9 is inserted and supported within the cylindrical shaft 6 so as to be able to reciprocate. Projects forward from the cylinder shaft 6.

A spool 10 is attached to the tip, and this spool shaft 9
are interlocked and connected to the bundle shaft 3 through a rotation to reciprocating motion conversion mechanism as described later, and the rotation of the bundle shaft 3 by the bundle 5 causes the spool 10 to reciprocate through the spool shaft 9 while the rotation frame 1 is rotated to wind the fishing line onto this spool 10.

Furthermore, a spinning reel with such a structure is already known,
A detailed explanation thereof will be omitted.

Accordingly, in the spinning reel having the above-described structure, the present invention constructs a rotation to reciprocating motion conversion mechanism interposed between the bundle shaft 3 and the spool shaft 9 as described below.

That is, a feed shaft 11 is mounted in the reel body 1 so as to be parallel to the spool shaft 9, and a reciprocating spiral groove 12 is formed in the feed shaft 11, while a cylindrical sliding groove is formed in the feed shaft 11. inserting the slider 13 and protruding a guide pin 14 from the slider 13 into the reciprocating spiral groove 12, and connecting the rear end of the spool shaft 9 to the slider 13; The slider 13 is reciprocated on the feed shaft 11 by rotation of the feed shaft 11, and the spool 10 is reciprocated together with the spool shaft 9.

On the other hand, the feed shaft 11 and the bundle shaft 3 are interlocked and connected.

To explain this interlocking mechanism below, within the reel body 1, the cylinder shaft 6 is provided with two partial teeth 16, 16, and an engagement regulating body having approximately the same diameter as the tip diameter of the partial teeth 16, 16. 17 is integrally formed, and a driven gear 18 is inserted and fixed at the front end of the feed shaft 11, so that the driven gear 18 and the feed gear 15 can freely rotate. An intermediate gear 19 is interposed between the intermediate gear and the intermediate gear.

The meshing teeth 20 of the gears 19 are formed with regulating teeth 20a having a long axial length for contacting the outer circumferential surface of the regulating body 17 and regulating free rotation every other time. As a result, the intermediate gear 19 is shifted to the feed gear 15 by one rotation of the cylindrical shaft 6 due to the rotation of the bundle shaft 3 degrees.
That is, as the feed gear 15 rotates, the partial teeth 16.16 of the gear 15 rotate by two teeth through the intermediate gear 19.
The gear 19 meshes with the meshing teeth 20, and rotates by two teeth.

As the feed gear 15 rotates, the gear 15
The partial tooth 16.16 is the meshing tooth 20 of the intermediate gear 19.
..., the rotation of this intermediate gear 19 stops, and this resting state also causes the meshing teeth 2 of the intermediate gear 19 to stop rotating.
The regulating teeth 20a... at 0... are the feed gear 1
In other words, the feed gear 15 is maintained by contacting the outer circumferential surface of the mesh regulating body 17 at
This causes the intermediate gear 19 to rotate intermittently, and when the rotating body is stopped, the intermediate gear 19 is restricted from inadvertently rotating.

Therefore, the feed shaft 11, which is interlocked with the intermediate gear 19 via the driven gear 18, is driven intermittently and is substantially rotated at an extremely low speed.

Therefore, due to the rotation of the feed shaft 11, the spool shaft 9 and the spool 10, which are operated via the slider 13, reciprocate at an extremely low speed relative to the rotational speed of the rotating frame 7.

The spinning reel of the present invention is constructed as described above, and when the handle shaft 3 is rotated by the handle 5, the cylindrical shaft 6 is rotated through the engagement between the master gear 4 and the pinion 8, and the rotating frame 7 is rotated. The fishing line is wound onto the spool 10 by the rotation of the rotating frame 7.

On the other hand, due to the rotation of the cylindrical shaft 6, the feed gear 15 and the intermediate gear 1 are
9. The feed shaft 11 rotates through each engagement of the driven gear 18, and the rotation of the feed shaft 11 causes the slider 13 to reciprocate on the feed shaft 11, causing the spool 10 to reciprocate together with the spool shaft 9. As described above, the fishing line is wound around the spool 10 by sequentially moving the device, in other words, the rotation of the rotating frame 7 causes the fishing line to be wound around the spool 10 in a spiral manner.

Therefore, the reciprocating motion of the slider 13 on the feed shaft 11 is as follows:
This is based on the advance angle of the reciprocating spiral groove 12 formed on the feed shaft 11, and since this advance angle is constant over the entire area of the reciprocating spiral groove 12, the reciprocating motion of the slider 13 is The winding of the fishing line onto the spool 10 is performed at a constant speed, so that the pitch of winding the fishing line around the spool 10 is constant, and the winding of the fishing line onto the spool 10 is performed at a constant speed.
Furthermore, due to the interlocking mechanism provided between the cylinder shaft 6 and the feed shaft 11, the reciprocating motion of the spool 10 relative to the rotational speed of the rotating frame 7 is extremely low, so that the fishing line can be wound parallel to the fishing line. The winding pitch on the spool 10 is extremely small, so that the so-called fishing line can be wound on the spool 10 without any gaps, and the amount of winding of the fishing line can be increased.

In addition, since the amount of fishing line to be wound up can be increased in this way, the amount of fishing line required during casting can be sufficiently covered by the fishing line on the surface layer of the winding section, which prevents the fishing line from coming into contact with the front flange of the spool during casting. Therefore, as illustrated in FIG. 1, the depth of the fishing line winding portion of the spool 10 is made much shallower than that of a normal spool, so that when the fishing line is pulled out, The contact resistance caused by the fishing line coming into contact with the front flange of the spool 10 can be further reduced.

In the embodiment described above, the intermittent feed gear 1 is provided on the cylinder shaft 6.
5, a driven gear 18 is provided on the feed shaft 11, and an intermediate gear 19 is provided between these driven gears 18 and the feed gear 15, so that the feed shaft 11 is intermittently driven with respect to the handle shaft 3. However, in addition, the intermediate gear 19 is eliminated, and the driven gear 18, like the intermediate gear 19, has meshing teeth that mesh with the partial teeth 16.16 of the feed gear 15, and an outer peripheral surface of the meshing regulating body 17. The feed shaft 11 may be configured to be driven intermittently with respect to the handle shaft 3 by providing regulating teeth having a long axial length for contacting with the feed gear 15 and regulating co-rotation with the feed gear 15. good.

As explained above, the spinning reel according to the present invention has a handle shaft with a master gear, a pinion that meshes with the master gear, a cylindrical shaft that supports a rotating frame, and a spool that is movably supported by the cylindrical shaft. In a spinning reel equipped with a supporting spool shaft, a feed shaft is mounted within the reel body so as to be parallel to the spool shaft, a reciprocating spiral groove is formed in the feed shaft, and a reciprocating spiral groove is formed in the feed shaft. The spool shaft is interlocked with the handle shaft, a slider is inserted into the feed shaft, a guide pin is protruded from the slider so as to protrude into the spiral groove, and the spool shaft is connected to the slider. Since the spool shaft is configured to be connected and reciprocated by the reciprocating movement of the slider on the feed shaft, the reciprocating speed of the spool can be made constant over the entire range of the reciprocating movement. , whereby the fishing line is wound around the spool by the rotation of the rotating frame at a constant pitch,
The fishing line can be wound parallel to the spool, that is, it has become possible to eliminate the disorder of winding of the fishing line, which occurs when a large amount of fishing line is wound on the deep side of the fishing line winding part of the spool, and yet, it is possible to wind the fishing line in parallel on the spool. There is no need to form a reciprocating spiral groove on the shaft. In other words, by providing a feed shaft with a reciprocating spiral groove separately from the spool shaft, we have simplified the overall production and reduced costs. be.

Moreover, on the cylinder shaft, the partial teeth and the tip diameter of the partial teeth are S.
゛In addition to providing an intermittent feed gear with a meshing regulating body having the same diameter, the feed shaft is provided separately from the spool shaft, and the partial tooth of the feed gear is engaged between the feed shaft and the intermittent feed gear. A driven gear is provided which includes meshing teeth and regulation teeth having a long length in the axial direction that contacts the outer peripheral surface of the meshing regulating body and restricts co-rotation with the feed gear, and the driven gear is Since the spool is coupled to the feed shaft and the feed shaft is driven intermittently relative to the bundle shaft, the reciprocating speed of the spool can be made extremely low relative to the rotation speed of the rotary frame.

Therefore, the fishing line can be wound onto the spool at extremely small pitches without gaps, and the amount of fishing line to be wound can be increased accordingly.

Furthermore, since a feed shaft provided separately from the spool shaft is used and an interlocking mechanism is provided between the feed shaft and the cylinder shaft, the reciprocating mechanism can be easily machined, and the amount of fishing line to be wound can be increased. Moreover, the overall structure is not complicated and the overall structure can be formed at low cost.
