Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing rod having an external guide, and more particularly, to a thread entanglement prevention structure for a top guide.

[0002]

2. Description of the Related Art A fishing rod with an outer guide may be entangled with a guide line, unlike a fishing rod with a through thread, but has been widely used since it is easy to manufacture and maintain. In order to compensate for the above-mentioned drawbacks of the fishing rod with an outer guide, the guide to be attached is inclined forward,
For example, a structure is adopted in which the left and right sides of the annular frame portion that holds the guide mounting foot and the guide ring are connected by inclined arm members. Also, for example, Japanese Patent Laid-Open No. 2001-2043
No. 07 discloses a structure in which a conical cover member is provided and is configured like a hollow fishing rod at first glance to prevent thread entanglement.

[0003]

However, it cannot be ignored that the former inclined arm member has a large specific gravity because it is formed of a metal member because of its durability. In particular, when it is used for the top guide, various forces act on the top guide through the fishing line, and therefore durability is an important design element, and since it is the tip, the prevention of heavy weight is also an important design element. From these viewpoints, it is difficult to make the shape long in the front and rear to sufficiently prevent the yarn entanglement. Further, in the case of the latter publication, the thread entanglement at the tip portion can be sufficiently prevented, but at the rear end position of the cover member, the thread entanglement cannot be prevented, and since it is a relatively long and large member, it is fatal as a fishing rod. It is unavoidable that a specific weight will occur. Therefore, an object of the present invention is to prevent yarn entanglement of the top guide while preventing the weight from being carried. Furthermore, the top guide has a pipe portion into which the tip portion of the rod is inserted, and usually the rod tip portion and the pipe portion are fixed with an adhesive, but this portion is maintained at about 200 ° C. by maintenance. This adhesive fixation can be removed by heating. In the present invention, when the yarn entanglement prevention member is damaged, after removing the yarn entanglement prevention member, a new yarn entanglement prevention member is inserted and arranged from the rear end of the pipe member.

[0004]

In view of the above object, according to claim 1 of the present invention, a metal pipe portion to be mounted on the tip portion of a rod and a pipe portion connected to the pipe portion are provided on one side in the radial direction of the rod tip portion. A frame body of a top guide having a metal annular frame body portion provided in a protruding shape and a guide ring held by the annular frame body portion, and a groove portion extending from the front end to the rear end,
It is formed of an elastically deformable member of a member having a smaller specific gravity than the pipe portion forming metal and the annular frame portion forming metal, and the tip end portion of the combination annular portion of the annular frame portion and the guide ring. The size is within the range of half the annular part on the pipe part side, the tip part can be held in contact with the combined annular part, and the outer shape is such that the fishing line does not easily get caught from the rear end part, and the width is generally left and right. Provided is a fishing rod having an outer guide which is enlarged and is provided with a thread entanglement prevention member having a maximum width at a tip portion or having a maximum width portion at an intermediate position.
The expansion of the width in the left-right direction becomes clear in the embodiment described later, but it means that the width becomes gradually larger as a whole even if the width is partially reduced as it goes forward.

Since the frame body of the top guide has the metal pipe portion, the metal annular frame portion connected to the metal pipe portion, and the guide ring, the strength can be maintained. Since the thread entanglement prevention member is formed of an elastically deformable member having a groove portion extending from the front end to the rear end, it can be attached and detached from the outer peripheral surface side of the pipe portion of the top guide through the groove portion, and damage can occur. Can be replaced at times. With the outer shape in which the fishing line is hard to catch from the rear end, the left and right widths are widened, and the tip has the maximum width, or has the maximum width in the middle and the tip is in contact with the combination annular part. Since it can be held, thread entanglement is prevented. In addition, the top guide is formed of a member having a smaller specific gravity than the pipe part forming metal and the annular frame part forming metal, and the tip part of the semi-annular part is about half of the pipe part side of the combined annular part. Size within the range,
Since it is the minimum required size in the vertical direction,
It is lightweight and prevents weight from being carried.

According to a second aspect of the present invention, there is provided a metal pipe portion to be attached to the tip portion of the rod, and a metal annular frame portion which is connected to the pipe portion and is provided on one side in the radial direction of the rod tip portion so as to project. When,
A frame body of a top guide having a guide ring held by the annular frame body portion, and a through hole that can be inserted into and removed from the pipe portion along the longitudinal direction thereof, rather than the pipe portion constituent metal, The annular frame body is made of a member having a smaller specific gravity than that of the metal, and the tip portion has a size within the range of a semi-annular portion which is about half of the pipe portion side of the combined annular portion of the annular frame portion and the guide ring. That is, the tip part can be held in contact with the combination annular part, and the lateral width is enlarged by the outer shape in which the fishing line is hard to catch from the rear end part, and the tip part is the maximum width or in the middle. A fishing rod having an outer guide, the fishing rod being provided with a thread entanglement prevention member having a maximum width portion at a position.

As mentioned above, the top guide (frame body thereof) can be removed from the tip of the rod. In the second aspect, the thread entanglement prevention member is inserted from the rear end of the pipe portion thus removed through the through hole, but the other effects are the same as those of the first aspect.

According to a third aspect of the present invention, the yarn entanglement prevention member has a flat shape, and one side of the wide surface faces the one side in the radial direction,
The one side in the radial direction is exposed along the pipe portion, or the outer surface of the meat portion on the pipe portion is flush with or lower than the innermost lower end of the guide ring, and when exposed, the pipe portion is exposed. Further, in the case where there is a meat portion on the pipe portion, the fishing rod having the outer guide according to claim 1 or 2, wherein the left and right edge portions are curved toward the one side in the radial direction as compared with the meat portion. I will provide a. At the position along the pipe of the thread entanglement prevention member, it is lower than or flush with the innermost lower end of the guide ring, and the left and right edges are flattened in a state of being curved toward the height of the guide ring. It is possible to reduce the weight by eliminating unnecessary meat while securing a space as large as possible for insertion into the guide ring inner opening.

In the present invention, when the tip portion has the maximum width, the maximum width is less than or equal to the maximum width in the same direction of the combined annular portion, and when the midway position has the maximum width, the maximum width is The width of the combined annular portion is not less than the maximum width in the same direction.
A fishing rod having the outer guide according to any one of 3 to 3. If the tip portion has the maximum width, if this width is larger than the maximum width in the left-right direction of the combination annular portion, it causes thread entanglement and is wasteful in terms of weight. These are prevented by keeping the maximum width of the part in the horizontal direction or less. The shape is preferably along the combined annular portion. Also,
When the midway position is the maximum width, the front part has a small width, and if this maximum midway width is smaller than the maximum width in the same direction of the combined annular part, there is a risk of entanglement with the front part. The maximum width of the combination annular part is made larger than this to prevent this.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in more detail with reference to the embodiments shown in the accompanying drawings. FIG. 1 is a side view of a fishing rod according to the present invention. Although the tip rod 12 is spliced in parallel with the base rod 10, the present invention is not limited to this example, and any other fishing rod form may be used. Each rod is made of a fiber-reinforced resin that is made of a synthetic resin such as an epoxy resin as a matrix and is reinforced with reinforcing fibers such as carbon fibers. An external fishing line guide 14 is provided on each rod and a top guide 16 is provided at the tip of the tip rod. Reference numeral 15 is a reel, which is located on the same side as each fishing line guide with respect to the fishing rod.

From FIG. 2 onward, each form of the top guide 16 is shown. 2 is a side view of the first embodiment, FIG. 3 is a plan view, FIG. 4 is a longitudinal sectional view, and FIG. 5 is a transverse sectional view taken along the line EE of FIG. The frame body of the top guide has a pipe portion 18, a ceramic guide ring 22, an annular frame body portion 20 for holding the guide ring 22, and a connecting portion 19 for connecting the annular frame body portion to the pipe portion. There is. Each member other than the guide ring is made of metal, and is strong in strength due to their connection.

The tip portion 12 of the tip rod is inserted into the pipe portion, which is usually fixed by using an adhesive. The combined annular portion of the annular frame body portion and the guide ring is provided in a protruding shape on one side in the radial direction of the rod 12 (upper side or lower side of the rod). In this example, it is projected upward. Although the combined annular body is inclined forward, the yarn entanglement prevention member 24 is attached in the present invention because the yarn entanglement cannot be prevented only by the frame body described above. First, it has a flat shape as a whole, and one side (surface) of the wide surface is directed to the protruding upper side, and the left and right edges 24
F is curved upward as compared with the pipe portion at the central position of the distance between the left and right edges.

A groove 24K is formed on one side of the wide surface from the front end to the rear end along the center line of the distance between the left and right edges.
By utilizing the elasticity of the member 24, the groove portion can be pressed against the pipe portion from the side to receive the pipe portion, and the member can be held by the pipe portion. Materials that have such elasticity and have a smaller specific gravity than the metals of the pipe portion 18 and the annular frame portion 20 include polyamide, ABS resin, expandable resin, and natural materials such as cork and wood. In order to improve the reliability of holding, an upright portion 24E that locks in the vicinity of the connecting portion 19 when mounted is provided on the rear surface side of the front end portion. For example, the holding of the pipe portion by the groove portion 24K is insufficient. Also, care is taken to prevent the member 24 from accidentally retracting during fishing.

As can be seen from FIG. 3 which is a plan view showing the left-right width of the thread entanglement prevention member 24, the left-right width is the smallest at the rear end (the rod base side) and gradually increases toward the front end at the front end. Is formed to the maximum. Further, this tip portion is in contact with the combined annular portion. Therefore, it is possible to prevent the fishing line from being entangled with the top guide including this member. Further, as shown in FIG. 2, the edge portion 24F gradually increases in height from the rear end portion toward the front end portion, and the yarn entanglement is effectively prevented. Moreover, as shown in FIG. 2 and FIG. 4, the tip portions of the left and right edge portions 24F of the member are at the position of the horizontal line passing through the opening center position of the combined annular portion. That is, the member 2 is extended over the range of the half annular portion of the lower half (pipe portion side) of the combined annular portion.
No. 4 is provided, the dimension is sufficient in the vertical direction from the viewpoint of preventing yarn entanglement, and it is not necessary to reach the upper half, and the weight is reduced as much as possible.

The tip of the member 24 is located radially outside the inner circumference of the semi-annular portion of the lower half of the combination annular portion on the pipe side, and secures a space for inserting the fishing line so that the fishing line comes into contact therewith. Making it difficult. In particular, above the pipe portion, which is the center position of the distance between the left and right edges, than the maximum height point P1 of the cross section at the innermost lower end angular position of the guide ring (expressed as the innermost lower end of the guide ring in the claims). Leaning (low). In the above example, the tip of the member 24 reaches the maximum width position in the left-right direction of the combined annular portion, but at a lower position with a width smaller than this, even if the shape follows the surface of the combined annular portion, Has almost the same effect.

Further, the lateral width of the member 24 in this example is maximum at the tip end portion, but becomes maximum at the midway position and may be somewhat reduced thereafter. In particular, the maximum width dimension at the midway position is a combination. If the width of the annular portion is not less than the maximum width in the left-right direction, yarn entanglement is effectively prevented. Further, the groove 24K is formed in the member 2
4 may be provided on the lower side instead of the upper side.

FIG. 6 is a plan view of the second embodiment of the top guide portion, and FIG. 7 is a cross-sectional view taken along the line GG of the arrow. Items that are different from the first embodiment will be mainly described. Member 24
The left-right width, which is the distance between the left and right edge portions 24F, is not necessarily in the form of gradually increasing from the rear end to the front end, includes the same dimensions, and has some contracted portions. However, the uneven shape of the edge portion is smooth, and the entanglement of the fishing line is prevented. In this way, it can be said that the width of the member 24 increases substantially as it goes forward. Further, although the tip end of the member 24 is located below the maximum position of the left and right width of the combined annular portion, the yarn entanglement is prevented as described above.

Further, the member 24 of this example is provided with a through hole 24H into which the pipe portion 18 can be inserted, extending from the front end to the rear end of the center portion in the left-right width. The member can be held in the pipe portion by press fitting the through hole into the pipe portion or by an adhesive. The central portion of the left-right width of the member, that is, the outer surface of the flesh portion of the member 24 immediately above the pipe portion is located at a position lower than the above-mentioned point P1 and prevents insertion resistance of the fishing line.

FIG. 8 is a plan view of the third embodiment, FIG. 9 is a longitudinal sectional view thereof, and FIG. 10 is a transverse sectional view thereof. The difference from the other form examples is that there is a pair of auxiliary frames 26 on the left and right of the pipe part
Is a frame body provided with. The auxiliary frame extends from the side portion near the central portion in the longitudinal direction of the pipe portion 18 toward the left and right side portions of the annular frame body portion 20 in a forward-spreading and upwardly rising slope, and It is welded to the side portion below the maximum width position. Therefore, the strength of the frame body is further improved as compared with the other embodiments, and the presence of the auxiliary frame can prevent the yarn entanglement to some extent. However, the effect of preventing the yarn entanglement is insufficient.

Therefore, the thread entanglement prevention member 24 has a through hole having a hollow portion having a substantially triangular shape in plan view so that the thread portion can be inserted from the rear end of the pipe portion 18 and the leading end thereof can reach the combined annular portion. 24H is provided. The member has a press-fitting relationship with the pipe portion at the rear portion of the through hole of the member and can be held, but an adhesive may be used. The shape of the member 24 in plan view is close to that of the first embodiment, and the width between the left and right edges gradually increases to become the maximum width at the front end. Further, the front end portion thereof is located at a position slightly lower than the height position of the maximum width in the left-right direction of the combined annular portion, but higher than the auxiliary frame 26. The rear end is behind the auxiliary frame. Therefore, the outer shape is such that the yarn entanglement can be prevented more effectively.
Also in terms of weight, since the frame body is made of a material having a lower specific gravity than the metal, it is possible to prevent the weight from being carried.

[0021]

As is apparent from the above description, according to the present invention, it is possible to provide a fishing rod capable of preventing the thread entanglement of the top guide while preventing the carry weight.
