Abstract

PROBLEM TO BE SOLVED: To provide a line guide for fishing, capable of decreasing the largeness of a protrusion formed in a ring-holding hole without decreasing the strength of a frame, capable of enlarging the range permitted for dimensional error of a guide ring, also extremely heightening the holding power of the guide ring by a frame, capable of making the external shape of a ring-holding part of the frame small in the view in the front and rear direction and thereby reducing the causing of entanglement of line, and capable of reducing the weight of the frame. SOLUTION: This line guide is obtained by using a material for a frame 23 thinner than the conventional one, forming a tacking protrusion 37 at the inner periphery edge 33a of a ring-holding hole 35, subjecting the ring-holding part 27 to a cylindrical reducing work without the neighbor of the inner perimeter edge 33a and fixing the cylindrical part to a guide ring 25 by an adhesive 39. The width of the protrusion in the front and rear direction becomes smaller as much as the thickness of the plate thined, and the adhesive area between the guide ring 25 and the ring-holding part 27 is increased and the decrease of the strength is prevented by carrying out the cylindrical reducing work of the ring-holding part 27.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing line guide mounted on a rod or a reel. Specifically, this is a line guide in which a rigid guide ring is internally fitted into a ring holding hole of a frame, and minute temporary fixing projections are formed on the inner peripheral edge of the ring holding hole, and two or more tips of the temporary fixing projections The present invention relates to a fishing line guide in which a guide ring is temporarily held by an inner peripheral edge of a ring holding hole and a tip of a temporary fixing protrusion, and the guide ring is adhesively fixed to a frame from that state.

[0002]

2. Description of the Related Art A line guide for guiding the running of a line (fishing line) is attached to a fishing rod and some reels. Many of today's line guides are constructed by fitting an annular guide ring into the ring holding hole of the frame and bonding it. Usually, the guide ring is made of a hard material such as ceramic due to wear and heat storage. And the frame is formed by a metal plate.

Since a guide ring made of ceramic or the like has a considerable dimensional error due to manufacturing, it is not actually possible to press-fit and hold all the manufactured guide rings as they are into the ring holding holes of the frame. Is impossible. For this reason, there has been a problem in that the number of guide rings that cannot be used merely because the size does not fit the frame is increased and the yield is deteriorated.

In view of the above, the present inventors first formed several small protrusions for temporary fixing on the inner peripheral edge of the ring holding hole in the circumferential direction, and deformed the frame by press-fitting the guide ring. Has developed a line guide that can absorb the dimensional error of the guide ring.
No. 477).

FIGS. 5 to 7 show a line guide described in the above publication. In the drawing, 1 indicates a guide ring, and 3 indicates a metal frame. This frame 3
Is a ring holding portion 5 having an annular shape and a mounting foot 7 for a rod body.
And the supporting legs 9 which are connected to each other, and the above-mentioned parts are integrally formed by pressing a relatively thick metal plate. Ring holding hole 11 which is a hole of ring holding portion 5
On the inner peripheral edge 11a, there are formed six small temporary fixing projections 13 arranged at equal intervals in the circumferential direction (the projections 13 are exaggerated in the drawing). When manufacturing the guide ring 1, the tolerance of the outer diameter is set to a plus tolerance from the diameter of an inscribed circle inscribed at the tips of the six protrusions 13.

Accordingly, when the guide ring 1 is pressed into the ring holding hole 11, the projection 13 is pressed by the guide ring 1 to deform the ring holding portion 5 (the projection 1).
1 instead of being displaced outwardly from one another
The portion between the two approaches the center side of the ring holding hole 11), whereby the guide ring 1 is press-fitted into the ring holding hole 11 in a press-fit manner. Thereafter, an adhesive is supplied between the outer peripheral surface of the guide ring 1 and the inner peripheral edge 11 a of the ring holding hole 11 to fix the guide ring 1 to the frame 3. In this way, the relative dimensional error of the guide ring 1 with respect to the frame 3 is absorbed by the deformation of the ring holding portion 5.

[0007]

By the way, this projection 1
3, in particular, it is desirable that the surface in contact with the guide ring 1 be as small as possible. That is, when the protrusion 13 is crushed or removed with the mounting of the guide ring 1, the dimensional error is easily absorbed and the yield of the guide ring is improved, and when the protrusion 13 is smaller, the deformation amount of the frame 3 is smaller. Done,
In addition, the impact applied to the frame 3 causes the guide ring 1
This is because it is possible to prevent transmission to a local area or reduce the impact thereof.

In this case, it is best to reduce the front-rear width of the projection 13 so that the projection 13 is easily crushed and the contact area with the guide ring 1 is reduced. However, it is considerably difficult to provide the projection 13 only on a part of the inner peripheral edge 11a of the ring holding hole 11 in the width direction, and even if it is possible, the production cost is high, which is not practical.

Therefore, it is conceivable to reduce the thickness of the frame 3 itself to reduce the front-rear width of the projection 13.
According to this method, since the projections 13 can be formed by ordinary press working, there is no problem that the production is troublesome, and this contributes to a desirable reduction in weight for the line guide. However, when the thickness of the frame 3 is reduced, the width of the inner peripheral edge 11a of the ring holding hole 11 is also reduced, so that the facing area between the guide ring 1 and the frame 3 is reduced. In this case, there is a problem that the bonding area between the guide ring 1 and the frame 3 is reduced, and the holding force of the guide ring 1 by the frame 3 is reduced. Since the holding force of the guide ring 1 in the line guide of this type of structure is mostly obtained by the adhesive force with the frame 3,
A reduction in the bonding area immediately leads to a reduction in the holding force, and rather, it is desirable that the bonding surface be large.

Further, in this type of conventional line guide, there has been a problem that the outer diameter of the frame 3 is increased by the height of the projection 13, so that the weight is increased and the line is easily entangled.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and a projection provided in a ring holding hole can be reduced without lowering the strength of a frame, and a dimensional error of a guide ring can be tolerated. The range can be expanded, the holding force of the guide ring by the frame can be greatly increased, and the outer shape of the ring holding portion of the frame as viewed from the front-back direction can be reduced, so that thread entanglement hardly occurs, and It is an object of the present invention to provide a fishing line guide capable of reducing the weight of a fishing line. Another object of the present invention is to provide a fishing line guide that can reliably prevent an impact applied to a frame from a direction in which the frame is most unlikely to be bent to reach a guide ring as it is via a projection. And

[0012]

In order to achieve this object, a fishing line guide according to the present invention comprises a guide ring made of a hard material and a ring holding hole in which the guide ring is held in an in-fit state. A small temporary fixing protrusion is formed on the inner peripheral edge of the ring holding hole, and a guide ring is formed at the tip of two or more temporary fixing protrusions or with the inner peripheral edge of the ring holding hole and the tip of the temporary fixing protrusion. A fishing line guide in which a guide ring and a frame are adhered and fixed while being held, and at least the periphery of the ring holding hole of the frame is drawn into a cylindrical shape while leaving a portion near the inner peripheral edge of the hole. The cylindrical portion and the guide ring are bonded and fixed.

According to the present invention, since the strength can be obtained by narrowing the ring holding portion into a cylindrical shape, the thickness of the frame can be made much thinner than the metal plate conventionally used. As a result, the front-rear width of the protrusion is inevitably reduced, and the press-fitting of the guide ring into the ring holding hole is facilitated, so that the range in which the dimensional error of the guide ring can be allowed can be expanded. In addition, since the shape of the ring holding part is a cylindrical shape with a certain distance in the front and rear direction, compared to the conventional ring holding part where there was only a distance corresponding to the plate thickness of the material used, the outer peripheral surface of the guide ring was The opposing area is increased, and therefore, the bonding area between the guide ring and the frame can be significantly increased, and the holding force of the guide ring by the frame is greatly increased.

In addition, since the ring holding portion of the frame is drawn into a cylindrical shape while leaving a portion near the inner peripheral edge of the ring holding hole, the outer diameter of the ring holding portion, that is, the dimension as viewed from the front-back direction is small. As a result, thread entanglement is less likely to occur, and the weight of the line guide can be reduced due to the reduced thickness of the frame.

According to a second aspect of the present invention, in the line guide for fishing according to the first aspect, the frame is provided with a rod mounting portion, and the guide ring is in contact with the temporary fixing protrusion or the inner peripheral edge of the ring holding hole. Is a position other than the top on the opposite side to the rod mounting portion. Normally, in a line guide attached to a fishing rod, the direction in which the frame is least likely to bend is the direction toward the rod body, and if an impact in this direction is transmitted to the guide ring as it is, the guide ring may be broken, According to the invention of this claim, since the guide ring does not contact the protrusion or the inner peripheral edge of the ring holding hole at the top opposite to the rod body mounting portion, the impact from the above direction is directly applied to the guide ring. Can be reliably prevented, and the reliability of the guide ring against cracking can be increased.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of a fishing line guide according to the present invention will be described below with reference to the embodiments shown in the drawings. In each embodiment shown in the drawings, the present invention is applied to a line guide of a type externally attached to a rod body. 1 to 3 show a line guide 21 according to the first embodiment. The line guide 21 includes a metal frame 23 and a guide ring 25 for passing a line.
Consisting of

The frame 23 includes a ring holding portion 27 for holding the guide ring 25 and a substantially tongue-shaped front and rear portion (a direction toward the upper right in FIG. 1 is a front side, that is, a rod). It is the front side.) It is composed of two mounting feet 29, 29 'and supporting legs 31, 31' before and after connecting the mounting feet 29, 29 'and the ring holding portion 27, and these parts are provided. Is integrally formed by pressing a light metal plate having good rust resistance, such as stainless steel, aluminum, or titanium.

This metal plate is approximately 80% thicker than the metal plate used for the frame of the conventional line guide using the same size guide ring. . For example, when the outer diameter of the guide ring 25 is 12 mm, a stainless plate having a thickness of approximately 1.0 mm is conventionally used, whereas the line guide 21 shown in this embodiment is not used. Thickness 0.
An 8 mm stainless plate was used.

The ring holding portion 27 has a substantially cylindrical shape whose length in the axial direction is extremely short for its diameter.
Its axial direction extends substantially in the front-rear direction, and its front end is a narrow circular band-like flange portion 33 bent inward. The hole defined by the inner peripheral edge 33 a of the flange portion 33 is a ring holding hole 35. On the inner peripheral edge 33a of the flange portion 33, three temporary fixing projections 37 arranged at equal intervals in the circumferential direction are formed. These temporary fixing projections 3
7 has a horizontally long substantially trapezoidal shape, and the height of the trapezoid is approximately 0.1 mm.
1 millimeter. One of the three temporary fixing projections 37 is located at the lower apex of the ring holding portion 27. Therefore, the temporary fixing protrusion 37 is opposite to the upper apex of the ring holding portion 27, that is, opposite to the mounting feet 29, 29 '. It is not provided at the top of the side.

The front leg 31 extends from the lower end of the rear edge of the ring holding portion 27 so as to be folded forward and downward, and is continuous with the front mounting foot 29. The rear leg 31 'has two right and left ring holding members. It extends rearward and downward from the left and right sides of the rear edge of the portion 27, respectively, and continues to the rear mounting foot 29 '.

The guide ring 25 is made of ceramic processed by a known sintering method or the like, and is formed in an annular shape. The intermediate portion of the outer peripheral surface 25a in the width direction is orthogonal to the center axis of the guide ring 25. It is formed flat when viewed from the direction in which it runs.

The design dimensional relationship between the diameter of the inscribed circle inscribed at the tips of the three temporary fixing protrusions 37 and the outer diameter of the guide ring 25 is such that the diameter of the inscribed circle is relatively smaller than that of the guide ring 25. The tolerance is set so as to be slightly smaller than the outer diameter, so that the outer diameter of the guide ring 25 is set to be slightly larger than the diameter of the inscribed circle except for extremely poor manufacturing.

The mounting of the guide ring 25 is performed as follows. First, the guide ring 25 is temporarily fixed to the frame 23. This temporary fixing is performed by inserting the guide ring 25 into the ring holding hole 3
5 by press-fitting. In this case, if the press-fitting is performed from the rear side, the operation is easy because the ring holding portion 27 functions as a guide member for guiding the guide ring 25 to the ring holding hole 35. When the guide ring 25 is pressed into the ring holding hole 35, the temporary fixing protrusion 37 is pressed by the guide ring 25, and the ring holding portion 27 is deformed (the position where the temporary fixing protrusion 37 is provided expands to each other, and The portion between the temporary fixing protrusions 37 that are formed is closer to the center of the ring holding hole 35).
5 is press-fitted inside. This fitting is performed until the intermediate portion of the outer peripheral surface 25 a of the guide ring 25 hits the temporary fixing protrusion 37.

Thereafter, the outer peripheral surface 25a of the guide ring 25
An adhesive 39 is supplied between the guide ring 25 and the ring holding portion 27 to fix the guide ring 25 and the ring holding portion 27 together. For this bonding, for example, an epoxy-based adhesive is used. The attachment to the rod body is performed by binding the attachment feet 29, 29 'to the rod body.

The line guide 21 is configured as described above. Accordingly, although the metal plate used as the material of the frame 23 is about 80% thinner than the metal plate used conventionally, the reduction in strength is prevented by the ring holding portion 27 being narrowed down to a cylindrical shape. Since the thickness of the frame 23 is reduced, the weight of the line guide 21 is reduced, the feeling of holding the fishing rod is reduced, and the front-rear width of the temporary fixing protrusion 37 is reduced. In this case, the temporary fixing protrusion 37 is easily crushed or easily deleted, thereby considerably increasing an allowable dimensional error of the guide ring 25.

Further, since the ring holding portion 27 is formed in a cylindrical shape having a certain distance in the front-rear direction, the area of the ring holding portion 27 facing the outer peripheral surface 25a of the guide ring 25 increases. The bonding area between the guide ring 25 and the frame 23 by the adhesive 39 is greatly enlarged, and the holding force of the guide ring 25 by the frame 23 is considerably increased. In addition, the ring holding portion 27 has the ring holding hole 3
5, the outer diameter of the ring holding portion 27, that is, the size as viewed from the front-rear direction, is reduced, so that thread entanglement is less likely to occur.

As described above, the temporary fixing projection 37 is located on the top of the ring holding portion 27, that is, the mounting feet 29, 29 '.
Since it is not provided on the top on the opposite side to the above, it is possible to prevent a strong impact from being applied to the guide ring 25. That is,
In a state where the line guide 21 is mounted on the rod body,
Since it is difficult to bend the frame 23 so as to be displaced toward the rod body, the impact applied from this direction cannot be buffered by the bending of the frame 23. However, the guide ring 25 is temporarily fixed at its top. Since it is not in contact with the protrusion 37, even if an impact is applied from a direction opposite to the rod body, the impact does not apply to the guide ring 25 without changing its direction. Therefore, the reliability of the guide ring 25 against cracks is considerably high.

In this embodiment, three temporary fixing projections 37 are provided. However, as the number of the temporary fixing projections 37 increases, the deformation of the ring holding portion 27 when the guide ring 25 is mounted is smaller. On the other hand, the resistance at the time of press-fitting of the guide ring increases. Therefore, this temporary fixing protrusion 37
It is desirable to reduce the height as the number increases. Generally, it is preferable that the height of the temporary fixing projections 37 be 0.3 mm or less.

FIG. 4 shows a line guide 21A according to a second embodiment of the present invention. The only difference between the line guide 21A and the line guide 21 is that a part of the inner peripheral edge of the ring holding hole is used for holding the guide ring 25. Therefore, the explanation will be made only for this difference, and for the rest,
The description will be omitted by giving the same reference numerals to the same parts in the line guide 21 for the respective parts of the drawing.

In this line guide 21A, only two temporary fixing protrusions 37 are provided, and the positions thereof are obliquely upper left from the center of the ring holding hole and obliquely upper right from the same center. The guide ring 25 is held at the inner contact 41, which is the lower apex of the inner peripheral edge 33a of the ring holding hole 35, and the tips of the two temporary fixing projections 37, that is, at three points.

Although the embodiment of the present invention has been described in detail above, the specific configuration is not limited to this embodiment, and there is a change in design without departing from the gist of the present invention. Are also included in the present invention. For example, in the embodiment, the number of the temporary fixing protrusions is one and three.
However, the number of the protrusions may be two or more if the guide ring is to be temporarily fixed only by the protrusion, and the inner peripheral edge of the ring holding hole is used for the temporary fixation. In this case, even one is possible.

In the case where a plurality of temporary fixing projections are provided, the intervals are not necessarily required to be equal. However, in order to prevent deformation of the frame from being distorted, it is preferable that the intervals are equal. The present invention is not limited to a line guide of a type mounted on a rod body, and can be widely applied as a line guide mounted on a reel or other various fishing tools, and the guide ring is provided with a flange. There may be.

[0033]

As described above, according to the fishing line guide of the present invention, the projection provided in the ring holding hole can be reduced without reducing the strength of the frame.
The holding force of the guide ring by adhesion can be greatly increased, and the outer shape of the ring holding portion of the frame as viewed from the front-rear direction can be reduced, so that thread entanglement hardly occurs, and
The weight of the frame can be reduced.

According to the second aspect of the present invention, it is possible to reliably prevent the impact applied to the frame from the direction in which it is least likely to bend to directly reach the guide ring via the projection.
