Description

  The present invention relates to a guide for sliding a fishing line wound / rewinded around a reel along a fishing rod.

FIG. 7 is a specific example showing a general fishing tackle. As shown in the figure, the fishing tackle includes a fishing rod (I), a fishing line (B), and a reel (C), and the fishing line (B) is attached with a needle (d) at the tip and a float (e) in the middle. .
A weight (f) is attached between the needle (d) and the float (e), and the fishing line (b) is wound around the reel (c). (B) can extend for a long time.

  The fishing line (b) slides along the line guide (g), (g), etc. attached to the fishing rod (b), and the fishing line (b) unwound from the reel (c) slides. The fishing line (b) can be stretched free from the top guide (chi) attached to the tip. Conversely, the same applies when the fishing line (b) is wound around the reel (c), and enters from the top guide (c) and slides along the line guides (g), (g).

By the way, line guides (G), (G)... And a top guide (H) for guiding the sliding movement of the fishing line (B) are attached to the fishing rod (I). Has a structure in which a ring-shaped guide ring is fitted in the ring holding hole of the frame.
Usually, the guide ring is formed of ceramics or a hard metal material in relation to wear resistance or heat resistance, and the frame is drawn by a metal plate.

By the way, since a guide ring made of ceramics or hard metal has a considerable dimensional error in manufacturing, it is possible to stably hold and fix all of the manufactured guide rings even if they are press-fitted into the ring holding holes of the frame as they are. Sometimes it can't be done.
That is, when the tolerance is so tight that the guide ring cannot be press-fitted into the ring holding hole, or when the guide ring is press-fitted, the tolerance may be loose and come off.

A “fishing line guide” according to Japanese Patent Application Laid-Open No. 11-225628 is a line guide in which a guide ring is held in a press-fitted state in a ring holding hole of a frame, and a guide ring is formed by a small temporary fixing protrusion provided in the ring holding hole. By temporarily fixing the ring, the dimensional error of the ring is absorbed, and the frame and the ring are finally bonded and fixed.
That is, the material of the frame is thinner than that of the conventional frame, provisional protrusions are provided on the inner peripheral edge of the ring holding hole, and the ring holding part is drawn into a cylindrical shape leaving a portion near the inner peripheral edge. The cylindrical portion and the guide ring are fixed with an adhesive.

Since the fishing guideline is a frame formed using a thin metal plate, the rigidity is low, and the guide ring cannot be firmly held only by being press-fitted into the ring holding hole. Therefore, an adhesive is used when fixing the guide ring to the ring holding hole. However, since the bonding process is required in addition to the guide ring press-fitting process, the number of manufacturing steps increases and the cost also increases.
"Line guide for fishing" according to JP-A-11-225628

  Thus, the conventional guide has the above-mentioned problems. The problem to be solved by the present invention is this problem, and provides a guide that is fixed so that the guide ring does not come off simply by being press-fitted into the holding hole without using an adhesive.

The fishing line guide according to the present invention has a holding hole in an annular frame, and a guide ring is fitted into the holding hole. Therefore, although the basic form is the same as that of a conventional guide, in the present invention, the frame is forged by metal, and the guide ring press-fitted into the holding hole of the frame is made of a very hard ceramic.
However, the outer shape of the frame is not necessarily limited to an annular shape.

By the way, the shape of the ring holding hole of the frame to which the guide ring fits is a polygon, and therefore the inner peripheral surface forms a plurality of contact planes. Therefore, the outer periphery of the guide ring is in contact with the flat surface. The flat surface is recessed and deformed to form a recess, and the guide ring engages with the recess and is fixed to the holding hole.
However, it is also possible to form a shallow groove on the outer periphery of the guide ring over the entire circumference and engage the abutment plane with this groove.
The guide is provided with a top guide attached to the tip of the fishing rod and a line guide attached between the reel and the tip. However, in the present invention, a specific means for attaching to the fishing rod is not limited.

  The guide according to the present invention has a frame that is not forged metal plate but forged, and the rigidity of the frame is higher than that of a conventional guide for metal plate drawn. Then, the inner peripheral surface of the holding hole of the frame having high rigidity is made a polygon, and the guide ring is fixed to the polygon holding hole without falling off.

That is, the contact plane that forms the polygonal holding hole is slightly crushed to form a recess, and the ceramic guide ring that fits in the holding hole is engaged with the recess where the outer periphery is formed. Absent. A hard ceramic guide ring is firmly fixed by fitting into a holding hole of a forged high rigidity frame.
And since the guide ring is made of ceramic, it is very hard, and when the reel is rewound or wound, even if the fishing line slides and rubs against the guide ring, the guide ring is hardly worn. .

The external view which shows the top guide attached to the front-end | tip of a fishing rod. (A) is a top view of a top guide, (b) is a bottom view. FIG. 2A is a cross-sectional view taken along the line AA in FIG. Top guide before the guide ring is fitted. Top guide with guide ring fitted. A specific example showing a line guide. Specific example showing a general fishing tackle.

  FIG. 1 is an embodiment showing the appearance of a guide according to the present invention, and is a top guide 1 attached to the tip of a fishing rod. The top guide 1 includes a frame 2 and a mounting portion 3, and the frame 2 has a ring body (ring) having a holding hole 4 therethrough. The attachment portion 3 has a cylindrical shape, and the attachment portion 3 is provided with a fitting hole 5. By the way, the top guide is attached to the tip of a fishing rod, and the tip of the fishing rod can be fitted into the fitting hole 5.

The top guide 1 is made of metal and forged, and its strength and rigidity are remarkably improved as compared with a top guide obtained by drawing a conventional metal plate. Therefore, the ceramic guide ring fitted and attached to the holding hole 4 does not fall off.
Here, the specific material of the top guide 1 is not limited, but generally a light and strong titanium material is suitable.

FIG. 2 shows a front view and a bottom view of the top guide 1. A holding hole 4 is provided through the frame 2 forming the ring body, and the holding hole 4 has a hexagonal shape. Therefore, a part of the inner peripheral surface 9 of the holding hole 4 protrudes to form the contact flat surfaces 6, 6..., And the corner portions 7, 7.
FIG. 3 is a cross-sectional view taken along line AA in FIG. A connecting portion 8 is formed at a corner portion between the frame 2 and the mounting portion 3, and strength against an external force acting on the frame 2 is ensured.

  The attachment portion 3 has an elongated cylindrical shape, and is provided with an insertion hole 5 penetrating in the axial direction. The tip of the fishing rod 10 is fitted into the fitting hole 5 and attached. Since the tip of the fishing rod 10 is thin, an appropriate length fits into the insertion hole 5, and sometimes the tip protrudes from the insertion hole 5. The insertion hole 5 has a polygonal cross section (see FIG. 5) so that the top guide 1 fitted and attached to the fishing rod 10 does not rotate.

FIG. 4 is a perspective view showing a state before the guide ring 11 is fitted into the holding hole 4 of the top guide 1. The guide ring 11 is a ring made of a ceramic material and has a central hole 14 at the center. Has penetrated. The outer peripheral surface 12 of the guide ring 11 is formed with shallow concave grooves over the entire circumference as required, and the inner peripheral surface 13 is a smooth arc surface with no corners with the side surface 15 being angular.
As is clear from the figure, the hexagonal holding hole 4 formed with the contact planes 6, 6... Is a part of the inner peripheral surface 9, and a protrusion partially protruding from the inner peripheral surface 9. It is formed as a part.

  FIG. 5 shows a case where the guide ring 11 is fitted and attached to the holding hole 4 of the frame 2, and the outer peripheral surface 12 of the guide ring 11 is a contact plane 6, 6.・ It can be engaged with and attached. The inner diameter of the circle inscribed in the contact plane 6 is slightly smaller than the outer diameter of the recessed groove formed on the outer peripheral surface 12 of the guide ring 11, and if the guide ring 11 is press-fitted into the holding hole 4, the contact The flat surfaces 6, 6... Are pressed and plastically deformed to form a recess, and the recess groove bottom of the outer peripheral surface 12 is pressed into and fixed to the recess.

  In this case, a slight gap 16 is formed between the inner peripheral surface 9 of the holding hole 4 and the outer peripheral surface 12 of the guide ring 11. The abutting planes 6, 6... Formed as a protruding part protruding from a part of the inner peripheral surface 9 are only plastically deformed and contacted, and the entire outer periphery of the guide ring 11 is in contact with the inner peripheral surface 9 of the holding hole 4. Not touching. That is, due to a dimensional error in manufacturing the guide ring 11, the gap 16 is formed when the outer diameter is small, and on the contrary, the gap 16 is hardly formed when the outer diameter of the guide ring 11 is large. In this case, the amount of plastic deformation of the contact flat surfaces 6, 6... Of the protrusions protruding from the inner peripheral surface 9 varies depending on the outer diameter of the guide ring 11.

  On the other hand, the guide ring 11 is press-fitted into the holding hole 4 without forming the concave groove on the outer peripheral surface 12, so that the guide ring 11 A part of the outer peripheral surface 12 can be engaged. The ceramic guide ring 11 is very hard and does not deform, but the outer diameter of the titanium frame 2 expands and the abutting planes 6, 6... Of the holding hole 4 undergo compressive plastic deformation.

FIG. 6 is a specific example showing the line guide 17. The line guide 17 is attached to a fishing rod between the reel and the top guide so that the fishing line slides along the fishing rod. That is, it corresponds to (g) in FIG.
By the way, the frame 18 of the line guide 17 has a holding hole 19 formed in a polygonal shape, and a ceramic guide ring is fitted into the polygonal holding hole 19. That is, it is the same as the frame structure of the top guide 1.
