Description

  The present invention relates to a component mounting structure on a surface of a fishing rod, and can be applied to an internal fishing rod or an external fishing rod.

An example of a structure for mounting and fixing a fishing rod component is disclosed in the following Patent Document 1 by the present applicant. This is a structure in which a locking hole is provided in the soot tube, and a projecting engagement portion capable of expanding in diameter is inserted in the part, and the diameter is increased after insertion to press-engage with the locking hole. Further, in Patent Document 2 by the present applicant, mounting and fixing using a screw member to fix the front and rear of the pedestal to the rod with a winding string and to make the guide member at the position of the fishing line introduction hole detachable from the pedestal A structure is disclosed.
JP-A-7-313022 JP 11-46632 A

However, in the former mounting structure, the protruding engagement portion of the component is pressed against the edge of the locking hole provided in the soot tube, and therefore the locking hole receives a force for expanding the diameter. Therefore, there is a possibility of adversely affecting the duct strength. In addition, there is a possibility that play will occur due to the pressure contact structure, and there is a problem in reliability as a mounting and fixing structure. Furthermore, since the protruding engagement portion protrudes inside the rod tube, in the case of a swing-type fishing rod, a problem such as the front section hitting the protruding engagement portion may occur when the front section is stored.
In the latter structure, a winding cord is used to fix the pedestal to the tub tube, and a double mounting structure is used in which a screw member is used to fix the component. The structure can be said to be useless.
Therefore, the problem to be solved is to provide a mounting and fixing structure for a fishing rod component which is simple and has a small influence on the strength of the rod tube.

  The invention according to claim 1 is a structure in which a fishing rod component is mounted and fixed on the surface of the rod tube, and has a nut component provided with a female screw to be screwed with the male screw component. Has a head with a large outer diameter, and at least the neck adjacent to the head has a non-circular cross-sectional shape, and the head of the nut part can be inserted into the position of the rod corresponding to the attached fishing rod part. A hole that is continuous to the front or the back of the hole and has a size such that the head cannot be inserted, and the neck can move in a predetermined direction from the hole in the front-rear direction. A part provided in a fishing rod part to be mounted on the other end side of the nut part with a continuous hole of a size that cannot be rotated around, the nut part located in the continuous hole with the head located inside the rod pipe Position the hole and insert the male thread part into the female thread of the nut part. Be fixed is engaged to provide a mounting structure for fixing the fishing rod components characterized by.

According to a second aspect of the present invention, there is a shoulder portion adjacent to the neck portion, and the shoulder portion of the nut part located in the continuous hole has a width that cannot be inserted in the penetration direction of the continuous hole.
According to a third aspect of the present invention, the head is plate-shaped and the plate thickness is in the range of 0.2 to 1.0 mm.

  According to the first aspect of the present invention, the head of the nut member is passed through the hole provided in the pipe, the neck is moved to the continuous hole with a predetermined orientation, and the nut member is held by an appropriate means such as a jig. On the other hand, the fishing rod component with the component hole facing from the other end (upper portion) is mounted and fixed to the surface of the rod tube by screwing the male screw component and the nut component. In this case, since the neck cannot rotate around the axis of the nut part in relation to the size of the continuous hole, the nut part can be tightened together without tightening the male thread part. After the tightening operation is completed, the rod tube is pressed from the inside by the back surface of the head of the nut component by screwing, and is pressed from the outside by the attached fishing rod component. Eventually, the hole peripheral part of the soot tube only receives the force which presses a soot tube surface, and does not receive the force by which a hole is expanded. Therefore, the influence on the strength of the tubule can be reduced, and the components can be mounted and fixed only by this screwing, and a simple structure without waste can be achieved.

According to the second aspect, even when the nut part is moved to the continuous hole and the hand is released, the nut part does not fall into the inside of the pipe due to the presence of the shoulder. That is, there is no need for a special jig for holding, and mounting and fixing work can be performed very simply.
According to the third aspect of the present invention, since the head portion of the nut part protruding into the inside of the tub tube is plate-shaped and has a thickness of 0.2 to 1.0 mm, the protruding amount is small. Therefore, in the case of a wrinkle structure, it is unlikely to obstruct the previous section storage.

  Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a longitudinal sectional view of an essential part of a first embodiment of a fishing rod component mounting and fixing structure according to the present invention, FIG. 2 is a transverse sectional view taken along line BB in FIG. 1, and FIG. 3 is an example of FIG. 4 is a part of a mounted fishing rod part, FIG. 5 is another part of a mounted fishing rod part, FIG. 6 is a nut part used for mounting and fixing, and FIG. 7 is another example of a nut part. FIG. This first embodiment is a structure for mounting and fixing a fishing line introducing component in a fishing line introducing portion of a through-hole fishing rod. A long hole 12 is formed in the rod tube 10 in the front-rear direction, and communicates with the long hole at a front position thereof. A continuous hole 14 is formed. For reasons described later, the width W2 of the continuous hole is narrower than the width W1 of the long hole.

  The mounted fishing rod part of this example is a bridge-shaped introduction part 16 made of a metal material shown in FIG. 4 and a nose part 18 made of a synthetic resin material attached to the introduction part 16 and having a hollow portion inside. A hard guide ring (not shown) such as ceramic is attached to the opening 16GH of the introduction component 16. The nose part is a member for guiding the tip portion of the threading tool by the inner surface of the nose when threading from the tip of the fishing rod, and for reliably leading it out from the guide ring. Near the ridge line portion of the nose part 18 is formed in a recess 18A having a depth slightly larger than the plate thickness of the introduction part 16, and the extension leg part on the front side of the opening part 16GH of the introduction part is fitted therein, respectively. A male screw component 22 (described later) is inserted through the provided component holes 16H and 18H, and fixed to the soot tube. In order to absorb a component accuracy error during assembly, the component hole 18H of the nose component is formed as a long hole that is long in the front-rear direction. Moreover, the continuous hole 14 is also formed long in the front-back direction for the same reason.

  The nut component 20 will be described with reference to FIG. A plate-shaped flange head portion 20T is provided at one end of a metal thick cylindrical nut component such as stainless steel. On the neck adjacent to the head, two flat portions 20K are ground and formed by milling so as to face each other in the 180-degree radial direction. The opposing width W2 'is formed to have a size close to the width W2 of the continuous hole (W2' is slightly smaller), but the other cylindrical portion outer diameter W3 is larger than the width W2 of the continuous hole. The head diameter W4, which is larger than the neck and is the maximum outer diameter of the nut part, is smaller than the width W1 of the long hole. In the axial direction, the end opposite to the head is a shoulder 20S. The maximum outer diameter of the shoulder is W3. In addition, the planar length of the left-right direction in FIG. 6A of the plane part 20K is formed longer than the thickness of the soot tube 10. Further, the total length of the nut part 20 (the length in the left-right direction in FIG. 6A) is such that the upper end position of the nut part 20 is lower than the lower face position of the part 16, that is, the upper end position of the hole 18H of the part 18 in the mounted and fixed state of FIG. The length is set to a low position.

  Therefore, the head of the nut part can be inserted into the long hole 12, and further, the surface direction of the pair of flat portions 20K is the longitudinal direction of the soot tube (the neck portion is in a predetermined direction). It can move to the continuous hole 14. Even if the hand is released from the nut part positioned in the continuous hole in this way, the nut part does not fall due to the presence of the shoulder 20S, and is caught and held by the edge of the continuous hole 14.

  The long hole 18H of the component 18 and the hole 16H of the component 16 are positioned and inserted into the other end portion (end portion opposite to the head portion) of the nut component 20 in this state. Then, a metal male screw component 22 such as stainless steel is screwed into the female screw portion of the nut component from the outside (above) of the component 16. At this time, since the cylindrical part outer diameter W3 is larger than the width W2 of the continuous hole 14, the nut part 20 can be fastened without being engaged with the hole edge wall of the continuous hole. That is, the head part of the male screw part presses the part 16 in the direction of the surface of the tub tube, and as described above, the entire length of the nut part is a predetermined length, so the lower surface of the part 16 presses the surface of the part 18. The part 18 is pressed against the surface of the soot tube. Moreover, the nut head 20 </ b> T is pushed up against the inner surface of the soot tube 10 so as to be brought into close contact. In addition, the pipe wall near the continuous hole 14 of the soot tube 10 is pressed outward by the head 20T of the nut part from the inside of the soot tube. That is, the soot tube receives a force so that the tube wall surface is sandwiched and compressed, and after being fastened, the force for expanding the connecting hole does not act.

For this reason, there is no force that tears the soot tube from the hole edge, and the mounting fixing structure of the present invention has a small effect on the soot tube strength.
In this example, the component 16 is made of metal. However, since the component 18 that is in direct contact with the fiber reinforced plastic pipe 10 is made of synthetic resin, the stress concentration on the pipe 10 when fastened and fixed. Is small. That is, the stress concentration at the site P1 in FIG. 1 is small. Further, the stress exerted on the synthetic resin part 18 by the end of the metal part 16, that is, the stress acting on the portion P2 in FIG. 1 is dispersed and stressed because the part 18 itself is a flexible member called synthetic resin. Concentration is eased.

  For the purpose of component stability after mounting, the width in the left-right direction of the long hole 18H of the component 18 is generally matched with the cylindrical portion outer diameter W3 of the nut component 20, as shown in FIG. Furthermore, the plate-shaped flange head portion 20T is about 0.4 mm thick, and the maximum protruding amount from the inner surface of the soot tube is about 0.5 mm. In the case of a swinging structure, the front side node (front side soot tube) In the case of storage, there is almost no catch. Even in the case of threading from the tip of the fishing rod (top-in method), there is very little possibility that the tip of the threading tool will be caught by the head 20T.

  A reference symbol G in FIG. 1 is a ceramic guide component and is located at the tip of the long hole 12. Moreover, although the front part of the bridge | bridging introduction | transduction component 16 and the nose part 18 is being fixed with the mounting | wearing fixing structure which concerns on this invention, a rear part can also be fixed similarly. However, the structure of the present invention may be applied to only one of the front and rear, and the other may be fixed with a wound thread.

  FIG. 7 shows another form example of the nut part, which is different from the case of the first example in that it is formed on a regular octagonal neck part except for the head part, and four pairs of two planar parts 20K facing each other. Exists. At the time of movement from the long hole 12 to the continuous hole 14, it can be moved in a direction orthogonal to the line connecting the two predetermined two flat surface portions 20K, for example, in the direction of the arrow line in FIG. In the threaded engagement with the male screw part, the flat portion interferes with the hole edge wall of the continuous hole 14 and does not rotate together. However, in this example, the part other than the head is the neck and there is no shoulder, so the nut part after moving to the continuous hole needs to be held by an appropriate jig.

  FIG. 8 shows an example in which the present invention is applied to the front and rear positions of a plate-shaped reel sheet component 26 on which a reel is mounted and fixed. In this example, it is fixed via a base 28 made of synthetic resin. The nuts 20 and the male screw parts 22 are attached and fixed through the part holes penetrating the parts 26 and 28 and the continuous hole 34 shown in FIG. The hole 32 through which the plate-like flange head portion of the nut part is inserted into the soot tube has a simple round hole shape here (it does not have to be a long hole as in the first example), but the length of the mounting part 26 Therefore, the continuous hole 34 is a long hole so as to absorb a component accuracy error during assembly, and its width dimension is smaller than that of the hole 32. The same applies to the rear position.

  FIG. 10 shows an example in which the present invention is applied before and after the foot portion of the guide part 36 of the outside fishing rod. In this example, it is fixed via a base 38 made of synthetic resin. The nuts 20 and the male screw parts 22 are attached and fixed through the part holes penetrating the parts 36 and 38 and the continuous hole 44 shown in FIG. The hole 42 through which the plate-like flange head portion of the nut part is inserted into the soot tube is also a simple round hole shape (it does not have to be a long hole as in the first example), but the foot part of the mounting part 36 Because of the relatively short length, the component accuracy error is small and the continuous hole 44 is not a long hole. Its width dimension is smaller than the hole 42. The same applies to the rear part.

  In the first example, the length of the male screw part can be increased by the presence of the part 18, and in the examples of FIGS. In a JIS standard product, a long screw component corresponds to a large screw diameter. Therefore, the strength is strong accordingly. The fixing force required for each mounting component is different, but the strength (size) of the screw component can be selected depending on whether or not the pedestal is provided and the thickness of the pedestal. If the nut part 20 and the male screw part 22 are made of metal as in the above example, the durability of the screw thread is improved, and the screw is less likely to be stupid. Further, the head of the nut part does not necessarily have a plate shape.

  INDUSTRIAL APPLICABILITY The present invention can be used for mounting and fixing components on a through-hole fishing rod or an outside-through fishing rod.
