[0002]

2. Description of the Related Art A single-bearing reel used as a fly reel has a reel body, a spool shaft fixed to the reel body by cantilever support, and a spool rotatably supported by the spool shaft. In addition, the single bearing reel,
In some cases, a sounding mechanism for generating a rotation sound as the spool rotates, a one-way clutch and a brake mechanism for preventing backlash when the fishing line is pulled out, and the like may be provided.

Further, in some single bearing reels, a spool is detachably attached to the reel body and the spool shaft. If the spool can be attached and detached, the above-mentioned operations such as inspection and replacement of the one-way clutch, adjustment of the brake mechanism, disassembly, cleaning, backlash adjustment, and release of thread jam can be easily performed. In a single-bearing reel having a removable spool, an engagement / disengagement mechanism for engaging / disengaging the spool shaft and the spool is provided. In the case where the spool is detachable, there is one in which mechanical components such as the above-mentioned sound generating mechanism and one-way clutch and brake mechanism are attached to the spool side so that these mechanical components can be attached and detached together with the spool.

[0004]

In a single-bearing reel having a removable spool, an opening is provided on the outer side surface of the spool in order to attach the mechanical parts such as the engaging / disengaging mechanism to the spool. I am trying to close it with a free lid. Therefore, a step or unevenness is formed on the outer surface of the spool by the lid. If there is such a step, the appearance is not good, and there is a problem that the fishing line is caught in the step or the like, which hinders the reeling-out of the fishing line and that dirt is accumulated in the depth of the step.

Also, every time the mechanical parts mounted inside the spool are inspected or replaced, it takes time and effort to remove and re-attach the lid. The spool needs a structure for attaching a lid, and it is also necessary to hermetically seal the spool so that water and foreign matters do not enter the inside of the spool. Therefore, the spool becomes large and the structure becomes complicated. The object of the present invention is to solve such problems, improve the appearance of the outer surface of the spool, prevent catching of fishing line and adhesion of dirt, facilitate handling of mechanical parts in the spool, and improve the structure of the spool. It is easy and small.

[Explanation of Solution] The basic structure of the reel body and the spool shaft may be the same as in the case of an ordinary single bearing reel. The basic structure of the spool including the tubular body portion and the pair of side plate portions is the same as that of a normal single-bearing reel. In the internal space of the tubular portion, one end on the side closer to the side plate of the reel body in the mounted state is open, and the spool shaft is inserted from this side. The end face portion is arranged on the other end side of the internal space. In the spool, the tubular body portion, the pair of side plate portions and the end face portion may all be integrally formed, or only the end face portion and one side plate portion may be integrally formed, and the remaining tubular body portion and the other side plate portion may be formed. It may be assembled and integrated. Each member such as the spool or the cylindrical portion forming the spool is manufactured by a usual processing method such as casting, forging, and shaving. The separately manufactured members may be integrally joined by a joining means such as welding, bolts and rivets.

The outer surfaces of the end surface portion and one of the side plate portions may be continuously connected by a smooth flat surface, or may be connected by a smooth curved surface, within a range that does not impair the action and effect of the present invention. There is no problem even if there are slight steps and irregularities. The engagement / disengagement mechanism can select a state in which the spool rotatably supported by the spool shaft is engaged so as not to slip out of the spool shaft, or a disengaged state in which the spool can be pulled out from the spool shaft. If so, the specific structure is not limited. The engagement / disengagement mechanism is disposed in the internal space of the tubular body and can be removed together with the spool from the spool shaft.

The engagement / disengagement operating portion performs an operation for switching the engagement / disengagement mechanism between the engaged state and the withdrawable state. The engagement / disengagement operating unit is arranged in the internal space of the tubular portion, like the other parts of the engagement / disengagement mechanism. However, the engagement / disengagement operating unit can be operated in a state where the spool is attached to the reel unit. Is partially exposed through the end face portion to the outside. Of the engagement / disengagement operation part, the part exposed to the outside of the end face part should not interfere with the fishing operation or the handling of the reel.
It is preferable that it has a smooth outer shape without significantly protruding to the outside.

As a concrete structure of the engagement / disengagement mechanism, a mechanical structure that can be engaged or disengaged between a spool shaft and an engagement / disengagement member rotatably supported by the spool shaft is used in a normal mechanical device. A mechanical structure can be adopted. For example, pins and holes, protrusions and recesses, protrusions and grooves, meshing teeth and teeth, and the like may be combined. The engagement / disengagement mechanism may be one in which the engagement member relatively moves linearly with respect to the spool shaft, one in which the engagement member swings or swivels, or one in which the linear motion and swivel motion are combined. The engagement / disengagement operating portion linearly moves, swings or swivels the engagement / disengagement member according to the structure of the engagement / disengagement mechanism. As the specific structure of the engagement / disengagement operating portion, the structure of the operating means in a normal mechanical device is adopted as long as the target engagement / disengagement member such as a protruding knob or lever can be operated.

Since the engagement / disengagement mechanism arranged in the internal space cannot be attached from the side of the internal space which is closed with the end face portion, the engagement / disengagement mechanism is opened from the opening opposite to the end face portion of the internal space to the internal space. It is inserted and attached to the spool.
The engagement / disengagement mechanism may be directly attached to the internal space of the tubular portion, but is attached to the fixed member,
If this fixing member is arranged in the internal space and fixed to the spool, the engaging / disengaging mechanism incorporated in the fixing member outside the spool is inserted into the internal space as the fixing member and incorporated in the spool. be able to.

If the engagement / disengagement mechanism has an urging means for urging the engagement / disengagement member in the direction of engaging the engagement groove, the engagement / disengagement mechanism will operate unless the engagement / disengagement operating portion is operated in the disengagement direction. The engaged state can be always maintained, and the spool can be reliably prevented from coming off the spool shaft. A spring member such as a leaf spring or a coil spring can be used as the urging means. If the engagement / disengagement member is supported by the rotation support means so as to be rotatable relative to the spool in the engagement / disengagement direction with the spool shaft, the engagement / disengagement operation can be reliably performed, and the engagement / disengagement operation can be facilitated. As the swivel support means, a normal swivel support structure can be adopted by combining a shaft and a hole arranged so as to be rotatable relative to each other. In the case of a combination of shaft and hole,
The shaft or the hole may be arranged on either side of the engagement / disengagement member side and the spool side.

When the operating protrusion arranged on the engaging / disengaging member moves in the surface direction of the end face portion, the end face portion is provided with a floating hole through which the operating protrusion can move. Since the floating hole has an opening space wider than the cross-sectional area of the operating protrusion, a gap is created between the operating protrusion and the floating hole. In this case, if the engaging / disengaging member has a shielding surface that closes the inner space side of the floating hole regardless of the floating position of the engaging / disengaging member, the internal space of the spool communicates with the outside through the gap between the floating hole and the operating protrusion. You can prevent it from happening.

A plate having a pair of spring pieces, one end of which is connected and the other end of which expands and contracts with each other, as the urging means, one spring piece abutting on the engaging / disengaging member and the other spring piece abutting on the inner surface of the internal space. If it has a spring, the engaging / disengaging member can be surely biased by a leaf spring having a simple structure having a substantially hairpin shape.
If the pair of spring pieces has a positioning means for positioning the leaf spring with respect to the engagement / disengagement member so as to be expandable / contractible, the spring pieces can be surely brought into contact with a predetermined member to apply a biasing force to the engagement member. You can The structure of the positioning means is not limited as long as it does not hinder the operation of the leaf spring. If the positioning means has a positioning shaft that is inserted through the center of the connecting portion of the spring piece, the positioning shaft is engaged with the spool-side fixed structure portion such as the fixing member by means such as fitting. By setting it in advance, positioning can be performed without impairing the expansion / contraction operation of the spring piece.

The engagement / disengagement member is used in a state of being engaged with the spool shaft. At this time, if the engagement / disengagement mechanism itself is displaced with respect to the spool due to the relative rotation between the spool and the spool shaft or the engagement / disengagement operation, the engagement / disengagement member is not held at the predetermined engagement position. There is a possibility of becoming. In order to prevent such a problem, it is preferable to provide a position deviation prevention means such as a rotation stopping mechanism that prevents the engagement / disengagement member from rotating relative to the spool. If a shaft and a hole that are arranged so as to be engageable with the engagement / disengagement member side and the spool side are provided as the positional deviation prevention means, the positional deviation can be prevented easily and reliably. More specifically, it is easy if the inner surface of the end surface portion has a detent hole provided in the axial direction of the spool shaft and a detent shaft that is erected on the engaging / disengaging member and inserted into the detent hole. With a unique structure, it can reliably stop rotation. If the shaft of the displacement prevention means and the hole also serve as the shaft and the hole of the swivel support means, the structure can be simplified.

1 and 22, a rotation braking mechanism 23 for braking the rotation of the spool 3 in the fishing line feeding direction, and an engagement / disengagement mechanism 24 for preventing the spool 3 from coming out of the spool shaft 2.

[Rotation Braking Mechanism] The rotation braking mechanism 23 has a cylindrical holder 30, a one-way clutch 31, a brake plate 32, and a pressing mechanism 25 for pressing the brake plate 32 against the holder 30. The holder 30 is rotatably attached to the spool 3, and has a body portion 30a that houses the one-way clutch 31 and a support portion 30b that is formed so as to project axially from the body portion 30a. There is. The support portion 30b has a structure shown in FIG.
As shown in the line sectional view), notches 30c and 30d for supporting a spring member (described later) that constitutes the sounding mechanism 4 are formed.

The one-way clutch 31 is disposed between the holder 30 and the spool shaft 2, and allows the holder 30 to rotate relative to the spool shaft 2 in the fishing line winding direction, but the holder 30 causes the spool 30 to rotate. It is prohibited to rotate relative to the shaft 2 in the fishing line feeding direction. The brake plate 32 is arranged between the end surface of the holder 30 on the side of the support portion 30b and the pressing mechanism 25.

A fixing member 33 is arranged on the side of the body 30a of the holder 30. The fixing member 33 is fixed to the spool 3 such that it cannot rotate relative to the spool 3. Further, between the fixing member 33 and the rolling bearing 22, a leaf spring 29 for urging the fixing member 33 and the rolling bearing 22 in a direction to separate from each other is arranged in order to eliminate looseness in the axial direction of the spool 3. ing.

The pressing mechanism 25 is provided with a receiving member 36 fixed to the side surface of the spool 3 by a screw 35, and a disc-shaped pressing plate which is arranged on the outer periphery of the receiving member 36 so as to be movable in the axial direction and faces the brake plate 32. 40 and a coil spring 42 mounted on the outer periphery of the receiving member 36 between the pressing plate 40 and the brake plate 32. The brake plate 32 is supported by the end portion of the receiving member 36 so as to be movable in the axial direction and non-rotatably in the radial direction, and the biasing force of the coil spring 42 presses the brake plate 32 against the side end surface of the holder 30. . In the receiving member 36, the rolling bearing 21 is arranged between the inner peripheral surface and the spool shaft 2, and the pressing plate 40 is provided on the outer periphery.
It has a tubular portion 36a in which the coil spring 42 and the brake plate 32 are arranged, and a flange portion 36b integrally formed at the end portion of the tubular portion 36a and abutting against the end face of the body portion 15 and fixed by a screw 35.

As shown in detail in FIG. 7, a brake adjusting protrusion 44 is attached to the side end surface of the pressing plate 40 opposite to the side adjacent to the coil spring 42. The brake adjusting protrusion 44 is fitted into a sliding hole 36c formed in the flange portion 36b of the receiving member 36 along the circumferential direction. A step portion 44 a is provided at a root portion of the brake adjusting protrusion 44 near the pressing plate 40. Brake adjustment protrusion 4
The step portion 44a of No. 4 is engaged with the step edge portion 36d provided on the edge portion of the sliding hole 36c. In the step edge portion 36d, the depth of the recess toward the inside of the pressing plate 40 changes while inclining from one side to the other side.

When the brake adjusting protrusion 44 is moved along the sliding hole 36c, the step portion 44a is guided along the step edge portion 36d as shown by a solid line or a two-dot chain line in FIG.
The brake adjustment protrusion 44 moves in the axial direction. When the brake adjustment protrusion 44 moves in the axial direction, the brake adjustment protrusion 4
The pressing plate 40 attached with 4 moves in the axial direction to change the pressing force applied to the coil spring 42, and the pressing force applied from the coil spring 42 to the holder 30 via the brake plate 32 changes. As a result, the braking force applied to the spool 3 that rotates by the feeding of the fishing line is adjusted.

[Sound Generation Mechanism] The sound generation mechanism 4 includes a spring member 37 supported by a support portion 30b of the holder 30 and an uneven portion 15b formed on the inner peripheral surface of the body portion 15, as will be described in detail with reference to FIG. Have. The spring member 37 is made of a substantially U-shaped strip-shaped spring material, and has a contact portion 37a that collides with the uneven portion 15b and a spring portion 37b that presses the contact portion 37a against the uneven portion 15b. . Holder 30 and body 1
When 5 rotates relative to each other, the spring member 37 and the uneven portion 15
b and bounce elastically and repeatedly to pronounce. Holder 30
No sound is generated when there is no rotational deviation between the body and the body 15 and they are synchronously rotating integrally.

[Engagement / Disengagement Mechanism] As shown in detail in FIGS. 2 and 4, the engagement / disengagement mechanism 24 has a substantially L-shaped plate shape, and one end of which is supported by the support pin 45 so as to be rotatable.
And a protruding operation knob 47 fixed to the other end of the engagement / disengagement member 46. The support pin 45 is fitted and supported in a support hole 18 a provided in the inner surface of the end surface portion 18. The engagement / disengagement member 46 is the engagement peripheral groove 2 formed at the end of the spool shaft 2.
There can be an engagement position where it can be engaged with a and an engagement release position (shown by a two-dot chain line in FIG. 4) which is disengaged from the engagement circumferential groove 2a.

The engagement / disengagement member 46 is constantly urged to the engagement position by the return spring 50 arranged on the side thereof. The return spring 50 is made of a strip-shaped leaf spring material that is bent like a hairpin, and has left and right pieces 50a and 50b and a connecting portion 50c that connects the left and right pieces 50a and 50b at one end. Return spring 50
Is supported by a support shaft 52 which is arranged at the center of the connecting portion 50c and fixed to the fixing member 33 side. Return spring 5
0, the left piece 50a abuts the side of the engaging / disengaging member 46, and the right piece 5a
0b is in contact with the inner peripheral edge of the fixing member 33, and
It is mounted in a state where the distance between 0a and 50b is narrowed. The elastic force that the left and right pieces 50a and 50b try to expand creates a force that urges the engagement / disengagement member 46 to the engagement position. Unless the operating knob 47 is operated, the engagement / disengagement member 46 is always locked in the engagement peripheral groove 2a of the spool shaft 2 and prevents the spool 3 from coming out of the spool shaft 2.

As shown in FIG. 5, the operation knob 47 is
The spool 3 is inserted into a free-moving hole 18b formed of an arcuate elongated hole that penetrates the end surface portion 18 and is exposed to the outside of the end surface portion 18. When the operation knob 47 moves along the floating hole 18b, the engagement / disengagement member 46 also moves together with the operation knob 47. However, the engagement / disengagement member 46 is moved to the floating hole 18b regardless of the moving position of the operation knob 47. Close the inner surface. Specifically, the area of the short side portion of the L-shaped engagement / disengagement member 46 is set to be sufficiently wider than the width and length of the floating hole 18b, and serves as a shielding surface 46a that closes the floating hole 18b. . By providing such a shielding surface 46a, it is possible to prevent water, dust or other foreign matter from entering the internal space 3a from the outside through the floating hole 18b.

[Operation of Reel] Next, the operation will be described. Although not shown, fishing line is wound around the outer periphery of the body portion 15 of the spool 3. When winding the fishing line, the handle 48 is operated to rotate the spool 3. Spool 3
Rotates relative to the spool shaft 2. At this time, the one-way clutch 31 allows the holder 30 to rotate in the winding direction with respect to the spool shaft 2. Therefore, the components stored in the internal space of the spool 3, such as the rotation braking mechanism 23 and the sounding mechanism 4, rotate together with the spool 3. To do. Therefore, the spool 3 smoothly rotates without braking the rotation and without producing a sound.

When feeding the fishing line from the spool 3,
The spool 3 rotates in the opposite direction to the above. At this time, since the spool 3 and the holder 30 are pressed against each other via the receiving member 36, the coil spring 42, and the brake plate 32, the holder 30 tries to rotate in the same direction as the spool 3. However, the one-way clutch 31 prohibits rotation of the holder 30 in the feeding direction. Therefore, the braking force set by the biasing force of the coil spring 42 acts on the rotational force of the spool 3, and the spool 3 is brought into a state in which a predetermined brake acts. Therefore, the spool 3 can be prevented from rotating more than necessary and the fishing line can be prevented from being pulled out excessively, so that the fishing line can be prevented from being entangled.

Further, when the fishing line is fed out, the receiving member 36 rotates together with the spool 3 and the holder 30 is prohibited from rotating, so that the body portion 15 of the body portion 15 is supported by the spring member 37 supported by the holder 30. Uneven portion 15b
Rotate relatively. This makes it possible to contact portion 37a of the spring member 37 with the rotation of the spool 3 collides with the concave portions of the concavo-convex portion 15 b, Could.

Next, as shown in FIG. 3, in this single bearing reel, the spool 3 is connected to the reel unit 1 and the spool shaft 2.
Can be removed from. The operation knob 47 is operated in opposition to the biasing force of the return spring 50, and the engagement / disengagement member 46 is disengaged from the engagement peripheral groove 2a of the spool shaft 2. The spool 3 is pulled out from the spool shaft 2 while keeping the operation knob 47 at the disengaged position. The spool 3 has a receiving member 36,
The mechanical components such as the pair of rolling bearings 21, 22, the one-way clutch 31, and the engagement / disengagement member 46 are removed from the spool shaft 2 while being mounted.

Spool 3 removed from spool shaft 2
Can replace internal mechanical parts, remove dirt, or adjust the braking force. By removing the spool 3, the winding direction of the fishing line can be changed from right winding to left winding, or vice versa. The screw 35 is removed from the spool 3 removed from the spool shaft 2, and the one-way clutch 31 together with the receiving member 36 and the like is taken out from the internal space of the spool 3. Then, the assembling direction of the one-way clutch 31 is reversed and mounted, and the reel is assembled by the work reverse to the above. As a result, the rotation allowable direction and rotation preventing direction of the one-way clutch 31 is reversed, the fishing line winding direction is to the right and left reversed.

In the spool shaft 2 of this single bearing reel, the diameter gradually decreases in the take-out direction, and there is no portion such as a flange having a large diameter. Therefore, the spool 3 and each component can be smoothly extracted without any obstacles when extracting the spool 3 and each component in the right direction of FIG. All the components that make up the engagement / disengagement mechanism 24 are fixed members 33.
Therefore, when the engaging / disengaging mechanism 24 is attached to / detached from / to the spool 3, the engaging / disengaging mechanism 24 can be collectively handled together with the fixing member 33. Specifically, at the time of assembly, by assembling the engagement / disengagement mechanism 24 with respect to the fixing member 33 outside the spool 3, assembly of the engagement / disengagement mechanism 24 is facilitated, and operation confirmation and adjustment of the engagement / disengagement mechanism 24 are performed. Is also easy to do. When the fixing member 33 having the engaging / disengaging mechanism 24 incorporated therein is inserted into the internal space of the spool 3 and the fixing member 33 is fixed to the spool 3 at a predetermined position, the assembling of the engaging / disengaging mechanism 24 to the spool 3 is completed. Conversely, spool 3
When the fixing member 33 is taken out from, the engagement / disengagement mechanism 24 is also removed from the spool 3.

In the above-described embodiment, all the components constituting the rotation braking mechanism 23, the engagement / disengagement mechanism 24, etc. are housed in the internal space 3a of the spool 3. Therefore, the space between the side plate 10 of the reel unit 1 and the inner flange 16 of the spool 3 can be narrowed, and the reel can be downsized. In addition, it is possible to prevent sand or the like from entering each mechanism. Furthermore, when the spool 3 is pulled out from the spool shaft 2, since no parts are mounted on the reel body side, the parts mounted on the reel body side may unintentionally come off when disassembled like a conventional product. It is easy to handle during assembly and disassembly work. Furthermore, it becomes easy to change from right-handed to left-handed.

[Other Embodiments] (a) In the above embodiment, in addition to the engagement / disengagement mechanism 24, the rotation braking mechanism 23 and the rolling bearings 21, 22 are provided inside the spool 3.
Although mechanical components such as the above were mounted, other mechanical components should be mounted inside the spool as necessary, or some mechanical components should be mounted on the spool shaft 2 side. You can also

(B) In the above-described embodiment, the end surface portion 18 projects to the outer surface of the spool 3, and the tip end portion of the spool shaft 2 is accommodated in the inner space of the end surface portion 18 with respect to the engaging circumferential groove 2a. However, the end surface portion 18 can be made to have the same flat surface as the outer flange 17. (c) In the above-described embodiment, the operation knob 47, that is, the engagement / disengagement operation portion projects outward from the surface of the end surface portion 18,
The engagement / disengagement operation portion may be arranged on the same surface as the surface of the end surface portion 18, or may be arranged in a state of being recessed inward from the surface of the end surface portion 18.

[0041]

In the single-bearing reel of the present invention, the outer surface of the spool is constituted by the end surface portion integrally formed with the side plate portion, so that the outer surface does not have a large conspicuous step or unevenness. As a result, the appearance is improved, and it is possible to prevent catching of fishing line and adhesion of dirt. Further, the structure of the spool can be simplified and the size can be reduced.
