No. 6,086,045.

[0003]

However, in the case of a hollow fishing rod, a large number of fishing line guides are provided so as to project inside the rod pipe so that the fishing line wet with water or soiled can be inserted into the rod pipe. Then, dust and water are accumulated between the guides, which leads to an increase in the resistance of the fishing line that is inserted while coming into contact with the accumulated water and the like. Also, it is difficult to remove dust and water between the guides,
Difficult to maintain.

Therefore, according to the present invention, the fishing line can be inserted so that it is guided by the fishing line guide and the insertion resistance is reduced while preventing the fishing line from coming into contact with water, and maintenance such as removal of dust is easily performed. The purpose is to provide a fishing rod throughout.

[0005]

In view of the above object, the present invention provides an inner tubular body which is detachably supported on the inner surface of the rod tube so as to provide a space for water droplets to flow between the inner surface and the inner surface of the rod tube.
A fishing line guide projecting inward from the inner surface of the inner tubular body, the fishing line guide being provided on the inner tubular body; and a drain hole for draining water from the inside of the inner tubular body to the space. And a rod pipe main body hole communicating with the space and discharging water to the outside of the rod pipe. The drain hole also includes a slit that can utilize the capillary phenomenon. The rod tube body hole also includes the tip hole of the rod tube such as the top guide. In the case where the inner tubular body is divided into a plurality of parts and each is connected by a connecting pipe, the connecting pipe is also a part of the inner tubular body here.
Further, the inner surface of the rod tube forming the space is made hydrophilic.

[0006]

Operation: The inner tubular body is formed with a water draining hole, and the water drained from the water draining hole falls into the space between the inner surface of the rod tube and the water, and this water passes through the rod tube body hole. Since the fishing line is discharged to the outside of the inner tubular body, the fishing line is hardly affected by water having a large resistance, and is smoothly guided by the fishing line guide protruding inward from the inner surface of the inner tubular body with a small resistance in the inner tubular body. Can be inserted. Further, if the separably supported inner tubular body is pulled out from the rod tube, the maintenance of the fishing line guide attached thereto can be facilitated. Further, if the inner surface of the rod tube is made hydrophilic, it is possible to prevent the water that has dropped into the space from adhering to the inner surface of the rod tube and then back intruding into the inner tubular body again, so that the water draining effect is enhanced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail based on the embodiments shown in the accompanying drawings. FIG. 1 shows a hollow lure rod as an example of a hollow fishing rod according to the present invention. The tip rod 12 is spouted to the original rod 10 via its splicing portion 12T. Further, a top guide 14 is attached at the end of the guide. A trigger 18 and a grip 16 are formed on the rear portion of the base rod 10, and a butt plug 20 is attached to the rear end surface thereof. By removing the butt plug, the tip rod 12 can be taken out from the rear portion. Further, when the buttocks are attached, the tip rod 12 can be stored and locked in the original rod 10 by the length of the original rod, and is configured to be compact when carried.

The base rod 10 is equipped with a nut 28 for moving the movable hood 24 above the trigger 18 back and forth at the front part of the grip 16. Further, a fixed hood 26 is arranged in front of the movable hood so as to face each other, and the legs of the reel 22 are fixed to these hoods to mount the reel 22 fixedly. On the other hand, a fishing line introducing guide 32 is formed at the tip of the base rod 10, and the fishing line 30 drawn out from the reel 22 passes through a ceramics guide ring 32G of the fishing line introducing guide 32 and is provided in the base rod 10. 32H
Through the rear end of the tip rod 12 to the inside.
When the guide ring 32G has a ring shape that is wider in the left-right direction than in the vertical direction, the guide line 32G is wide in correspondence with the movement of the fishing line 30 in the left-right direction when the bearing reels 22 are used. Reduce. The rod rod body hole WH for draining water is formed in the main rod wall below the fishing line introducing guide 32, and the rod pipe for draining water is also provided in the lower wall slightly forward of the joint 12T of the tip rod 12. A body hole WH 'is formed. The portion of the rod tube body hole WH 'is formed thick so that the strength is not insufficient.

FIG. 2 is a partial longitudinal sectional view of the tip rod 12.
The inner tubular body T whose rear end is held by the resin holding body HG holding the ceramic guide ring G1 includes a plurality of tubular body elements T1, T2, T3 and a connecting pipe for press-fitting and holding them inside. It is composed of P2 and P3. The inner tubular body T is inserted into the tip rod, and the holder HG is attached to the tip rod 1
Each connection pipe is configured to come into contact with the inner wall surface of the inner tubular body when it is held by being screwed into the female screw portion of the inner periphery of the second joint portion 12T. Therefore, the inner tubular body T is the tip rod 12
When mounted inside, the inner tubular body is held so as not to wobble, and a space WS is formed between the inner tubular body and the inner surface of the tip rod 12.

On the other hand, the inner tubular body T has a large number of drainage holes H.
And is formed between the tubular body elements on both sides inside each of the connecting pipes P2, P3 so that the inner diameter thereof is smaller than the inner diameter of each tubular body element. Holds the guide rings G2 and G3. Therefore, when the fishing line 30 is inserted into the inner tubular body T to carry out fishing, the fishing line is guided by the ceramic guide rings and smoothly inserted, and the attached water droplets pass through the water draining hole H to form the space. Fall to WS. Therefore, water droplets are removed from the inside of the inner tubular body T, and the resistance when the fishing line 30 is inserted is significantly reduced. Further, the holding body HG and the connecting pipe P
2, P3, a water channel W1, which connects the spaces WS, respectively.
W2 and W3 are formed, and water drops that have fallen into the space WS are made to flow behind the tip rod 12 to be discharged to the outside from the rod tube body hole WH ', and further to the rear part of the holder HG,
It can be discharged to the outside from the rod tube main body hole WH provided in the lower portion of the tip portion of the original rod 10. It can also be discharged from the top guide 14 at the tip of the tip rod 12.

The inner tubular body T can be formed of synthetic resin or fiber reinforced prepreg similar to the tip rod or the base rod, but if this is inserted into the tip rod 12, the bending rigidity of the tip rod 12 is high. Therefore, if the tip rod 12 is inserted up to the middle L1 and is not arranged at the tip L2,
As a result, the tip portion of the tip rod 12 remains soft and becomes a pointed rod. In addition, the shape of the tip rod 12 may be formed in a tapered shape from the rear end to an intermediate position, and the tip portion thereof may have a substantially straight shape. In this case, the rigidity is high up to the cut position of this taper. , The tip of which is a tongue rod with low bending rigidity. Therefore, it is preferable that the inner tubular body T is inserted and arranged up to the cut position of the taper because the tone of the rod having the leading edge does not change significantly.

When the inner tubular body T is inserted into the region L1, the region L2 forms a smooth unevenness on the inner surface thereof when the tip rod 12 is formed, for example, by the method described later with reference to FIGS. 8 and 9. In addition, while the fishing line 30 is guided by the convex portion, water droplets attached to the fishing line are scraped off, temporarily stored in the concave portion, and occasionally discharged from the top guide 14 to prevent the fishing line 30 from adhering to the fishing line. By coating the surface of the irregularities with a fluororesin or the like, the thread slipperiness is improved and water droplets are discharged smoothly.

A cross section of the connecting pipe P3 is shown in FIG. 3, but the same applies to the other connecting pipes P2. In addition, as shown in FIG. 4, the outer shape of the connecting pipe P3 ′ may be elliptical, and a space W3 ′ through which water droplets flow may be formed between this and the tip rod 12. In addition, by configuring the inner surface of the tip rod 12 to be hydrophilic so that water droplets that have dropped from the water draining holes H of the inner tubular body T spread and adhere to the inner surface of the tip rod and do not enter the inner tubular body T again. Good. As the hydrophilic member, gold, silver,
There is lead, etc., and in addition to plating or vapor deposition of gold or silver, if the surface is made to be a fine rough surface, the weight increase is reduced and the hydrophilic effect is improved. Further, even if a layer in which the surface of the fluororesin is roughened is formed, it becomes hydrophilic.

To form the water drainage hole H, a method of forming a hole in the resin pipe at the time of forming the resin pipe or after the resin pipe is formed as in the above-described embodiment, or a wire-like member is wound in a coil shape. There are methods such as a method in which gaps that occur at times become drainage holes, and a method in which a wire mesh-like member is formed into a cylindrical shape to form an inner tubular body and the mesh serves as a drainage hole. If the water drainage hole H is too large, it is difficult for the threading tool to pass through the inside of the tubular body, or the fishing line drips and water droplets in the space WS are reattached, which is inconvenient. Set the size so that it does not occur. However, if it is small, it is difficult to drop into the space due to the surface tension of the water droplet, which is inconvenient. For this reason, a thin slit-like drainage hole (having a width of 1 mm or less, preferably 0.1 to 0.5 mm) that is cut by a knife along the longitudinal direction or the spiral direction of the tubular body T.
With this, the water droplets inside the tubular body are effectively discharged into the space WS by the capillary phenomenon.

Further, in order to be able to adjust the bending rigidity of the tip rod 12, the cross-sectional shape of the inner tubular body T may be changed to an elliptical cross-section or the like, and the multiple drainage holes H may be formed at the circumferential position. Instead of arranging them evenly in the direction, the tip rod 12 holds the inner tubular body T, and the tip rod 12 is arranged in the left and right side regions when it is spouted and spliced to the base rod 10, and the bending rigidity in the vertical direction is increased. If it is used by lowering the bending rigidity compared to the left and right direction, a fishing rod with a soft tone will be obtained. Further, if the inner tubular body T is rotated by 90 degrees and held, it becomes a fishing rod of a hard tone. Therefore, if a circumferential alignment mark for the inner tubular body T and the tip rod 12 and a circumferential alignment mark for the joint portion of the original rod 10 and the tip rod 12 are attached, the inner tubular body T You can adjust the circumferential position of to get the desired tone.

In order to clean the guide rings G2 and G3 arranged in the tip rod 12, the tip rod 12 is pulled out from the rear end of the base rod 10, and the inner tubular body T is held from the tip rod 12 by a holder. With HG, pull it out backwards and connect each connecting pipe P2
It is easy to remove the tubular body elements T1, T2, T3 from P3 and clean the guide rings G2, G3 in the short connecting pipe. In addition to connecting the internal tubular body T using the connecting pipe as described above, each tubular body element T1 ′, T2 ′, T in which the drainage holes are omitted as shown in FIG.
There is also a structure in which 3'and T4 'are connected by a thread or wire RB. In this case, the tubular body elements are reliably pulled out at the same time in the connected state, and the guide ring G attached to the end of each tubular body element is bent and exposed as shown in FIG. 6 (b). Easy maintenance such as cleaning. Further, in order to float so as to provide a space with the tip rod 12, an annular member may be fitted into these tubular body elements and inserted into the tip rod.

The inner tubular body may be a curved tube T '(the drainage hole is not shown) as shown in FIG. If formed into such a curved tube, a space WS 'in which spiral water droplets flow is formed simply by inserting it into the tip rod 12. Such a curved pipe can be formed by, for example, fixing a coil spring in a spiral shape and solidifying it with a synthetic resin or the like. Further, when the fishing line is inserted, it is guided by the internal convex portion formed by the spiral.

FIG. 7 shows that the inner tubular body T'is supported by the spiral strip 12S integrally formed on the tip rod 12 'to form a spirally continuous space WS' through which water drops flow, and the inner tubular body T'is formed. The state where the spiral fishing line guide GR is formed inside is shown. Since the spiral line 12S merely serves to support the inner tubular body T ', its cross-sectional shape is not limited, but the fishing line guide GR for guiding the fishing line needs to smoothly guide the fishing line without damaging the fishing line. The cross-sectional shape must be smooth.

The spiral strip 12S and the spiral fishing line guide G
A method of forming R will be described with reference to FIG. Spiral strip 12S
In the case, a thick band-shaped member 42 is spirally wound around the cored bar 40. In this winding, the winding is performed so that the gap SP exists between the side edges of the strip-shaped member. Also, the thick member 42 is
In addition to leather, silicon, rubber, etc., metal may be used as long as it can be wound. A fiber reinforced prepreg string member or the like is arranged along the gap SP, and a fiber reinforced prepreg sheet for forming a tip rod is further wound on the string member, and thereafter, by heating according to a conventional method, a spiral strip is formed inside. An integrally formed tip rod 12 'of 12S is formed.

In the case of the fishing line guide GR, a strip-shaped thick member 42 is wound so that the gap SP exists like the spiral strip 12S. Ceramic fibers for fishing line guides, other wires, or string-shaped fiber-reinforced prepregs are laid along this gap, but if they are formed in the same manner as the above-mentioned spiral strip 12S, the fiber-reinforced fiber forming the inner tubular body T'is formed. A resin such as a prepreg or a synthetic resin material flows into the gap SP to form a corner on the surface of the fishing line guide wire or the like, which may damage the fishing line at the time of guiding or cause a problem that the guide is not smoothly operated. Therefore, the gap SP is covered with a thin flexible member, the above-mentioned fishing line guide wire or the like is laid along the gap SP, and the fiber reinforced prepreg sheet or the like for forming the inner tubular body is wound on the gap SP to form by heating.

By so doing, it is possible to prevent the corners from being formed by the resin flowing on the surface of the fishing line guide wire, etc.
A smooth surface fishing line guide GR can be integrally formed on the inner surface of the inner tubular body T ′. The thin flexible member can be formed of polyethylene naphthalate (PEN), polyethylene terephthalate (PET), or the like having high heat resistance. Further, the fishing line guide GR may be annular rather than spiral,
The same applies to the spiral strip 12S. In the latter case, in order to allow water droplets to flow into the rod tube body hole, the space W is provided in the spiral strip 12S.
A notch hole for communicating S'is formed.

As described above, the gap SP is formed by surrounding the core metal surface and the side edge of the thick band-shaped member 42, and as shown in FIG. 9, the thick band-shaped member 42 is formed on the core metal 40. Are overlapped and wound, and the stepped recess SP on the surface
Considering the same as the above gap, the spiral strip 12S and the fishing line guide G
R can be formed. Further, the internal tubular body may not be pulled out as described above, but may be fixed to a rod tube such as a tip rod. Further, in the present invention, the fishing rod is not limited to the swing-out type, and may be a spliced joint or a single rod.

[0023]

As is apparent from the above description, according to the present invention, the fishing line can be inserted while being prevented from coming into contact with water and being guided by the fishing line guide to reduce the insertion resistance.
In addition, it is possible to provide a fishing rod that is easy to maintain, such as removing the adhesion of dust.
