Description

  The present invention relates to a fishing spinning reel having an improved support structure between a front flange portion in the spool and a spool shaft support portion.

2. Description of the Related Art Conventionally, a fishing spinning reel rotates a rotor by rotating a handle, and moves a spool supported by the reel body back and forth to move a fishing line around a fishing line winding body of the spool. Is wound and held in parallel.
The spool is formed by a front flange portion, a fishing line winding body portion, a rear flange portion, a rear skirt portion, a spool shaft support portion, and a rib. Generally, a plurality of radial arrangements are arranged between the radially inner side of the rotating drum portion and the outer periphery of the spool shaft support portion with a predetermined interval in the circumferential direction.
By configuring the ribs as described above, it is possible to significantly reduce the thickness between the spool of the spool and the spool shaft support portion, thereby reducing the weight.
On the other hand, in order to allow the rotor to enter the inside of the fishing line winding body, a plurality of ribs arranged at equal intervals in the circumferential direction are formed on the radially inner side in the vicinity of the front flange portion to support the spool shaft. The structure for supporting the part is conventionally known.

However, since the ribs are usually arranged radially, when the fishing line is wound around the fishing line winding body, the fishing line winding body is radially inward due to the tightening force and tension applied to the fishing line. Since the diameter is reduced and the tightening force is transmitted to the spool shaft support through the rib, the support is tightly fitted to the spool shaft. As a result, it is difficult to attach and detach the spool. The problem that becomes is pointed out.
Further, since the ribs are arranged radially, the ribs support the force f in the winding direction of the fishing line applied to the fishing line winding body due to the tension of the fishing line caused by drawing out the fishing line by a large fish or rooting, etc. If the ribs are narrowed, the fishing line winding body cannot be supported.
For this reason, there is a limit to making the rib thinner, especially in the case of a spool that forms a rib in the vicinity of the front flange, the rib must be thicker, and there is a feeling of holding weight due to an increase in weight on the front side of the spool. There is an increasing concern about the burden on anglers due to prolonged fishing.
Referring to FIG. 8, the rib 4k extends radially outward from the center of the spool shaft support portion, and the center extends from O ₀ and the lines extending from the center to the outer periphery are X, X-rays and splines. - when the intersection of the outer periphery of the spool shaft supporting portion 4a of the intersection of the diameter of the Q _0, X-ray and the front flange portion near the P _0, the tension is applied to the fishing line spool - Le periphery (fishing thread winding barrel portion) intersection acts force F to rotate the P ₀ direction (fishing line winding direction), is applied weighting F ₁ in the direction tilted ribs on rib 4k.
In order to withstand this force, the rib needs to have a certain thickness.

In order to solve the above-mentioned problem, Patent Document 1 discloses that a fishing line winding is performed at the time of winding a fishing line by inclining a rib formed over substantially the entire width of the winding body inside the fishing line winding body with respect to the radial axis. A configuration is disclosed in which a diameter of a rotating drum portion is reduced to prevent transmission of a tightening force to a spool shaft support portion, and a spool wound with a fishing line can be easily attached and detached.
Japanese Utility Model Publication 4-45506

However, in the configuration of Patent Document 1, in the case where a rib is formed on the radially inner side in the vicinity of the front flange portion to allow the rotor to enter the inside of the fishline winding drum portion as described above, Since the tightening force of the fishing line wound around the spool shaft does not act at all on the spool shaft support portion, the effect of Patent Document 1 cannot be achieved at all.
Further, the configuration of Patent Document 1 is formed by inclining a rib at a predetermined angle to the rear side in the direction of winding of the fishing line with respect to a radial line x extending in the radial direction through the center of the spool. It is difficult to suppress the force in the rotational direction applied to the fishing line winding body when the tension is applied to the fishing line, and the rib is deformed.
When the state is described with reference to FIG. 9, the center is O ₁ , the intersection of the center line X ₁ of the width of the rib 4m and the outer periphery of the spool shaft support portion 4a is Q ₁ , the diameter near the X ₁ line and the front flange portion, When the intersection and P _1, the tension is applied to the fishing line spool - Le periphery acts force F to the (fishing thread winding barrel portion) intersection P ₁ in the direction of rotation (fishing line winding direction), the intersection Q ₁ is X due to the offset in the winding direction rear side of the fishing line from the line, the F is applied, it is applied force F ₂ to defeat rib 4m.
The ribs 4m to the intersection P ₁ so inclined with respect to the X-ray, since the component of the force toward the center line X ₁ direction radially outer rib width fa 'is applied, pulling against the ribs Directional force is applied, and the weight applied to the ribs is increased as compared with the conventional radial ribs.
Therefore, in order to maintain the strength of the ribs, the strength can be maintained only by countermeasures that increase the weight, such as increasing the thickness of the ribs, increasing the number of ribs, and expanding the range in which the ribs are provided.
Therefore, in Patent Document 1, a rib is formed over substantially the entire inner width of the fishing line winding body to cope with the deformation of the rib. However, in order to obtain a sufficient strength of the spool, the rib is formed over a wide range. There is a limit to weight reduction.
In the case where the rib is formed on the radially inner side near the front flange portion, the cylindrical portion of the rotor enters the fishing line winding body portion, so that the range in which the rib can be formed is limited and sufficient ribs are formed. It is difficult to obtain strength.
As a result, the rib may be damaged, and it is difficult to divert the inclined rib configuration as in Patent Document 1.

Further, as shown in FIG. 10, the rib 4n extends radially outward from the center of the spool shaft support portion 4a, with the center extending from O ₀ and the lines extending from the center to the outer periphery being X, X-rays and splines. Assuming that the intersection of the outer periphery of the shaft support portion 4a is Q ₀ and the intersection of the X-ray and the diameter in the vicinity of the front flange portion 4b is P ₀ , the weight F ′ applied to the intersection Q ₀ when the tension F is applied to the intersection P ₀ Is a distance La from the spool axis O ₀ to the intersection point P ₀ and a distance Lb from the spool axis O ₀ to the intersection point Q ₀ , F × La = F ′ × Lb, F ′ = FLa / Since Lb, the intersection point Q ₀ is given a greater weight than the intersection point P ₀ .
Therefore, in order to make the joint strength at the intersection point P ₀ and the intersection point Q ₀ closer to each other, it is necessary to maintain the relationship of la <lb.

A problem to be solved is, the rib spool - in the structure extending radially from the center of the spool shaft supporting portion radially outward, takes weighted F ₁ in the direction tilted ribs on rib order to withstand this force, the ribs A certain amount of thickness is required or the weight is increased.
Further, if the rib is inclined rearward in the direction of winding the fishing line as in Patent Document 1, when a force F in the rotational direction acts on the outer periphery of the spool, a force F _{2 in the} direction of tilting the rib is applied and the rib. Since a force component fa ′ directed radially outward is applied to the rib, a tensile force is applied to the rib, so that there is a drawback in that the load applied to the rib is increased as compared with the conventional radial rib.

  An object of the present invention is to provide a spinning reel for fishing which can obtain sufficient support strength even if the ribs of the spool are formed thin.

According to a first aspect of the present invention, there is provided a spool supported by a reel body via a spool shaft, a rotor rotatably supported by the reel body, and the rotor. A pair of bale support members that are supported and reversibly attached to a fishing line discharge position and a fishing line winding position, and a fishing line that is attached to one side of the bale support member and guides the fishing line to the spool. In a fishing spinning reel with a guide,
The spool is positioned on the radially outer side of the outer cylindrical body formed by the front flange portion, the fishing line winding body portion, the rear flange portion, and the rear skirt portion, and the outer cylindrical body. A spool shaft support portion, and a plurality of ribs that are joined to both the vicinity of the front side end portion of the outer cylindrical body and the spool shaft support portion to support the spool shaft support portion; The center of the spool shaft support portion side joint is displaced forward in the fishing line winding direction from the line connecting the center of the front outer cylindrical body side joint of the rib and the spool core. Is a summary.
The gist of claim 2 of the present invention is that the outer cylindrical body, the rib, and the spool shaft support portion are integrally formed.
The gist of claim 3 of the present invention is that the left and right widths of the center of the support portion side joint portion of the rib are formed wider than the left and right of the center of the front outer cylindrical body side joint portion of the rib. Is.

According to the first and second aspects of the present invention, the center of the spool shaft support portion side joint portion of the rib is formed from the line connecting the center of the outer cylindrical body side joint portion of the rib and the spool shaft core. By deviating forward in the rotational direction, the rotational load applied to the rib by the tension of the fishing line can be dispersed radially inward in the direction in which the rib extends, so the front end of the outer tubular body When the rib is formed in the vicinity, the support strength with which the rib supports the outer cylindrical body is increased.
Therefore, even if the rib is formed thinner than the conventional thickness, it is possible to obtain a sufficient support strength and to reduce the weight.
According to the third aspect of the present invention, the load applied to the rib is formed by forming the left and right sides of the center of the support portion side joint portion to which a load higher than the left and right widths of the center portion of the outer cylindrical body side joint portion of the rib is formed wider. The stress concentration in the vicinity of the joint on the support side due to the difference between the ribs can be eliminated, and the optimum rib width can be obtained according to the stress that differs for each radial part of the rib. It becomes possible to prevent deformation of the rib due to tension.

It is deviated forward in the direction.

  The present invention will be described below with reference to the illustrated embodiments. FIGS. 1 to 5 show a first embodiment, FIG. 1 shows a side view of a fishing spinning reel, and FIG. 2 shows a fishing spinning reel. 3 is an enlarged sectional side view of the spool, FIG. 4 is a front view of the spool, and FIG. 5 is an enlarged front explanatory view of the spool.

A bail 14 is attached between the other bail support member (not shown) and the attachment portion 13 of the fishing line guide portion 12.

The spool shaft 3 is reciprocated back and forth by an unillustrated oscillating mechanism provided in the reel body 1.
The front side of the spool shaft 3 has a large diameter portion 3a, a rotation preventing portion 3b provided on the large diameter portion 3a, a circumferential groove 3c which is a small diameter portion provided on the front side of the large diameter portion 3a, and a circumferential groove. It is formed with a screw portion 3d on the front side of 3c.
The spool shaft support portion 4a of the spool 4 is fitted to the outer periphery of the large diameter portion 3a of the spool shaft 3, the retaining ring 15 is fitted to the circumferential groove 3c, and the knob 5 is attached to the screw portion 3d. 16 is screwed together.
The outer shape of the spool 4 includes an outer cylindrical body 4p composed of a front flange portion 4b, a fishing line winding body portion 4c, a rear flange portion 4d, and a rear skirt portion 4e, and a plurality of ribs 4f. The spool shaft support portion 4a is formed with a rotation stop hole 4g at the center of the spool shaft support portion 4a, and a through hole 4h is formed between the ribs 4f.
The spool shaft support portion 4a is supported by the plurality of ribs 4f joined to the inner peripheral surface in the vicinity of the front flange portion 4b, which is in the vicinity of the front end portion of the outer cylindrical body 4p, and the rib 4f The center Q of the spool shaft support portion 4a side joint portion 4o is wound from a line X connecting the center P of the outer cylindrical body 4p side joint portion 4l of the rib 4f and the shaft core O of the spool 4.

As described above, in FIG. 5, the center point of the radially outer joint portion of the rib 4f is P, the center point of the radially inner joint portion of the rib 4f is Q, the axial center of the spool 4 is O, in FIG. When a line connecting the center point P and the shaft core O (a line extending radially from the spool shaft core) is X, the line X connecting the center point Q is displaced forward in the fishing line winding direction. The force F in the rotational direction applied to the outer periphery of the spool (the fishing line winding body) can be distributed in the extending direction of the rib 4f by the radially inward force fa on the axis x in the extending direction of the rib 4f. I can do it.
Thus the smaller the force F ₃ which acts to defeat the ribs, since the direction of the force is reduced to defeat the rib 4f compared to the ribs of a prior art radial ribs or the Patent Document 1 configuration, the thickness of the rib 4f Even if the thickness is reduced, made thinner, or the range in which the ribs are formed is reduced, the necessary and sufficient strength can be maintained, or the weight can be reduced.

When the fishing spinning reel is configured as described above, the center Q of the joint 4o on the spool shaft support 4a side in the rib 4f is the center of the joint 4l on the outer cylindrical body 4p side in the rib 4f. By deviating forward from the line X connecting P and the spool axis O to the fishing line winding direction, the rotational load applied to the rib 4f by the tension of the fishing line is radially inward in the extending direction of the rib 4f. Therefore, when the rib is formed in the vicinity of the front end portion of the outer cylindrical body, the support strength with which the rib 4f supports the outer cylindrical body 4p is increased.
Therefore, even if the rib 4f is formed thinner than the conventional thickness, sufficient support strength can be obtained and the weight can be reduced.
