Description

  The present invention relates to a joint type fishing rod.

  Unlike other joint-type fishing rods, the swing-out type fishing rod has the merit that the rod does not come off while using the fishing rod, but generally requires a lot of work to disassemble the rod. In particular, in a swing type fishing rod with an outer guide, the outer guide may be in the way and cannot be disassembled. In particular, when the top guide or the like has an outer guide fixed with respect to the soot tube, the protruding outer guide cannot often pass through the inside of the rear soot tube and cannot be disassembled. .

However, in a joint type fishing rod, it may be necessary to replace a rod such as a tip rod for cleaning or, in some cases, a change in the tone of the rod or breakage, but it cannot be replaced unless it can be disassembled. Moreover, sufficient cleaning is not easy.
Therefore, the problem to be solved is not limited to the case with an outer guide, but it is possible to provide a joint type fishing rod that can be joined and fitted in the same manner as a conventional swing type fishing rod while using a fishing rod, and can be disassembled when desired. is there.
That is, an object of the present invention is to provide a joint type fishing rod having both the advantages of the conventional swing type joint wind and the advantages of joint methods other than the swing type, such as the side-by-side type.

In the invention which concerns on Claim 1, it is a surface located inside the circle | round | yen of the circumferential direction outline of the base part outer periphery of a front side side pipe, Comprising: The shape which extended in the longitudinal direction and cut the circumferential direction circle | round | yen of the said base part outer periphery The cut surface is formed at one or more N locations in the circumferential direction, and is located on the inner side of the circle in the circumferential contour of the inner periphery of the tip of the rear side tube, and extends in the longitudinal direction. circumferential direction contour circle cut surface shape obtained by cutting the said front rod tube N and places formed in the corresponding circumferential direction arranged in the cut face provided on the front as the rear rod is cut surface of the rear rod tube It has an inclined region that approaches the center of the tube, and the front side stub tube base portion and the rear side stub tube tip portion face each cut surface of the front side stub tube base portion and the rear side stub tube tip portion. At the relative angle position, the front side tube tube base part can be inserted into the rear side tube tube tip part, and can be relatively rotated in the fully inserted state. If the front side tube is moved in the forward direction at an angular position that is relatively rotated so as to deviate from the face-to-face state, the joint portion is formed to fit in the middle. Providing a joint type fishing rod.
It is allowed to have a solid bowl or a solid part in the soot tube. In other words, the tip end may be a solid end or the front portion of the front side canal may be a end. The surface located inside the circle of the circumferential contour is a surface located inside the circle in which the circumferential portion remaining in the real product is smoothly continued. This surface includes a plane having a zero curvature, a groove ( A curved surface including a (concave shape). Further, the fact that the cut surface of the rear side pipe has an inclined region that approaches the center of the rear side pipe toward the front side means that the entire cut surface may be an inclined region, and a partial length range is an inclined region. It may be.

In the invention according to claim 2, the outer periphery of the base portion of the front side tubule has a conical shape with a front taper, and the conical portion is a surface located inside the circle of the circumferential contour of the conical portion, Extending in the longitudinal direction and parallel to the central axis of the front side tube, forming a cut surface in the shape of the circumferential contour circle of the conical portion in one or more N locations in the circumferential direction, The inner periphery of the tip of the soot tube is a straight cylinder or a conical shape with a pre-taper taper, and the cylindrical part or the conical part is a surface located inside the circle of the circumferential contour of the cylindrical part or the conical part. Extending in the longitudinal direction and forming a cut surface having a shape in which the circumferential contour circle of the cylindrical portion or the conical portion is cut at N locations in a circumferential arrangement corresponding to the cut surface provided in the front side tube, rear side the cut surface of the rod tube has an inclined area that approaches the center of the front as the rear rod pipe, said front rod pipe base portion and the front In the relative angular position where the cut surface of the front side tube tube part and the rear side tube tube part face each other, the front side tube tube part can be inserted into the rear tube tube part, If the front side tube is moved forward at an angular position that is relatively rotated so as to deviate from the facing state of the cut surfaces, it is formed to a size that fits in the middle. Provided is a joint type fishing rod characterized by comprising a joint part.

In the invention which concerns on Claim 3, the inclination angle and substantial with respect to this back side pipe center axis line of the inclination area | region of the said rear side pipe cut surface are provided in the circumferential part surface which is not a cut surface of the base part outer periphery of a front side pipe. The joint type fishing rod according to claim 1 or 2, which has a region having the same inclination angle.
It can be said that the circumferential surface which is not the cut surface on the outer periphery of the base portion of the front side pipe is the remaining portion of the outer peripheral surface of the base portion before being cut. The fact that the angles are substantially the same means that a manufacturing error is allowed and the difference in this range is the same.
The invention according to claim 4 provides the joint type fishing rod according to any one of claims 1 to 3, wherein each of the rods is made of fiber reinforced resin, and each of the cut surfaces is a flat surface.

In the invention according to claim 5, the cut surface of the front side tube and the cut surface of the rear side tube are surfaces formed in a spiral shape in the same direction with respect to the longitudinal direction of each tube. Provide the described fishing rod.
In the invention which concerns on Claim 2, although a cut surface is a form extended in a longitudinal direction, it is a form extended in a spiral direction here.
In the invention which concerns on Claim 6, said N is 2 or more, The cut surface of N places provides the joint type fishing rod of any one of Claims 1-5 arrange | positioned at equal angles in the circumferential direction.
A seventh aspect of the present invention provides the joint type fishing rod according to the sixth aspect, wherein the N is 2, 3 or 4.

In the invention which concerns on Claim 1, the angle position of the cut surface of the outer periphery of a front side tub tube base part and the cut surface of the rear side tub tube tip part inner periphery is match | combined, and the base part of a front side tub tube is in the front part of a rear side tub tube (The cut surface and the like of the front side tubule base portion are formed so as to have a size that can be inserted), so that it is inserted to a necessary position, and thereafter, the cut surfaces are relatively rotated from a state where they face each other to a different state. In this relative position state, if the front side tube is pulled out, the cut surface of the rear side tube faces the circumferential part (uncut circumferential part) adjacent to the cut surface of the front side tube, so the rear side The cut surface of the soot tube has a larger distance from the center of the saddle than the cut surface of the front soot tube (in short, the diameter is large). ) In addition, the cut surface of the rear side pipe has an inclined region that is closer to the center of the rear side pipe as the front side, so that the more the front side pipe is pulled out, the more tight the fitting becomes. In other words, the so-called joint sense of swing-out joining is obtained.
The inventor, in a conventional fishing rod with a swing-out joint structure, even if a fixed outer guide is attached to the tip, makes it possible to replace the tip rod, or for the convenience of maintenance such as cleaning, It came to this invention from the idea whether it cannot be made separable.

In the invention according to claim 2, the form of claim 1 is somewhat limited such that the direction of the cut surface is the longitudinal direction, etc., and the operational effects are the same as those of claim 1.
In the invention according to claim 3, the circumferential surface of the outer periphery of the base portion of the front side pipe has a region with the same inclination angle as the inclination angle of the cut surface of the cut surface of the rear side pipe. When mated and fitted, they are pressed against each other along the longitudinal direction, and the fitting force is strongly stabilized.
In the invention which concerns on Claim 4, since a cut surface is a plane, the cut surface of an outer periphery of a front side tub tube base part can be easily formed with a milling machine after a tub tube molding. In addition, the inner peripheral cut surface of the rear side pipe tip is formed by a cored bar at the time of forming the side pipe, but the cut surface corresponding to the cut surface is easily formed on the outer periphery of the cored bar tip part by a milling machine. Can be formed.

In the invention according to claim 5, the direction of the cut surface is the spiral direction (inclination direction instead of the longitudinal direction in plan view), and therefore, it is necessary to relatively rotate according to the spiral direction angle at the time of joining. Even after the splicing is completed, the relative rotation of the fishing rod is rarely inadvertent or failed to complete, and even if there is a risk that it will come off if the relative rotation is reversed, the fishing rod is usually linear in the longitudinal direction. Since the force to be pulled out acts, there is an effect that it is difficult to come off.
In the invention according to claim 6, since the cut surfaces are arranged at an equal angle, when the front side tube before the drawer fitting is rotated, the rotation is performed at the same predetermined angle in both the left and right directions. Since the angle can be adjusted, the angler can easily operate.

  In the invention according to claim 7, when the cut surface is 2, the front side tube tube base portion is inserted into the rear side tube tube tip portion, and then rotated 90 degrees back and forth, and is fitted well. Rotate around 60 degrees and pull out, and in the case of 4, rotate around 45 degrees and pull out. In relation to the width dimension of the cut surface (the smaller the width dimension), there is a margin in the angle error of the rotation operation, but the cut surface is 4 within the scope of this claim 5 unless the width dimension is extremely large. Even in the case of rotation aiming at the minimum angle of 45 degrees corresponding to the case, for example, even if it was rotated only 30 degrees (or rotated 60 degrees) in the actual operation, it can be fitted if it is pulled out at the relative angle as it is Yes. Thus, in the range of this Claim 5, there is a margin of rotation operation angle error. Therefore, it can be rotated to an angle at which it can be quickly fitted by the sense of the hand, but if there are more cut surfaces, it will be too easy to rotate even with a little rotation, and the cut surfaces will again face each other carelessly. It is difficult to quickly grasp the relative angular position at which it can be fitted.

Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1 is a cross-sectional view of a joint type fishing rod according to the present invention, showing a portion near a base portion 10A of a tubular head rod 10 as a front side rod and a portion near a front portion 20A of a head rod 20 as a rear side tube. FIG. 2 is a side view showing a state in which the tip heel is separated from the heel, FIG. 2 is a side view in the middle of inserting the tip heel in FIG. 1 and reaching the joint fitting, and FIG. 3 is taken along the line CC in FIG. FIG. 4 is a side view of a state in which it is rotated relative to the predetermined angle from the state of FIG. 2 and further pulled out and fitted, and FIG. 5 is an enlarged cross-sectional view taken along line EE in FIG. These are the expanded longitudinal cross-sectional view of the rear side tubule of the state of FIG. 4, and the cross-sectional views (b) and (c) by the arrow line F1-F1 and F2-F2, respectively. Hereinafter, it is the same even if the front side tube is assumed to be Hochiji (first middle rod) and the rear side tube is regarded as a combination of other vertical tubes such as the second middle tube. Each soot pipe is a soot pipe made of fiber reinforced resin in which a synthetic resin such as an epoxy resin is used as a matrix and is reinforced with a reinforcing fiber such as carbon fiber.

  The spike 10 has a shape in which the large-diameter portion that is the base portion 10A and the small-diameter portion 10B on the front side thereof are connected by a steep taper portion 10C, but there is no steep taper portion and the outer diameter is smooth. It may have changed. The base portion 10A may have a basic original shape based on the shape of the outer peripheral surface 10S having a circular circumferential contour such as a straight cylinder, a front thin cone (table), or a back thin cone (table). Shape. Planar cut surfaces 10H are formed at two locations 180 degrees apart from the side of the conical cylinder by the work of a milling machine. This cut surface is formed in parallel to the central axis of the spikelet. As a result, as shown in FIG. 1, it has a trapezoidal shape with a wide rear side and a narrow front side, or an isosceles triangular shape.

  The hochi mochi 20 has a straight cylinder, a front thin cone shape, and a rear thin cone shape of the inner peripheral surface 20S of the tip portion 20A, but here is a straight cylinder. On the inner side of the cylinder, cut surfaces 20H are formed in two positions 180 degrees apart from each other, corresponding to the cut surface of the tip rod. This cut surface is also formed in a flat surface here, and approaches the center of the hot pot as it goes in the forward direction of the front portion 20A. That is, as shown in FIG. 6, the distance from the central axis (in the radial direction) is shorter toward the front side. Accordingly, as shown in FIG. 1, the cut surface has a trapezoidal shape having a wide front side and a narrow rear side, or an isosceles triangle shape.

  Here, the length of the head portion and the length of the head portion are set to the same length here, but the lengths may be different. In addition to the above, the radial dimensions of the joints 10A, 20A are as shown in FIG. 2, that is, at the relative angular positions where the cut surface 10H of the spikelet and the cut surface 20H of the spikelet face each other. It is necessary to be able to insert the head part into the head part. As will be described later, as shown in FIG. 4, it is necessary to fit the head portion and the head portion. However, if the technical idea of the present application is understood from the entire description of the present application, the selection of these dimensions is a design matter for those skilled in the art.

  As shown in FIG. 2, the head end portion is sufficiently inserted into the head end portion at a relative angular position where the cut surface 10 </ b> H of the head tip faces the cut surface 20 </ b> H of the head tip. In FIG. 2, for the sake of easy understanding, the line corresponding to the broken line of Hochimochi in FIG. 1 is a one-dot chain line. In this case, it inserts until the rear end of the base part of the tip end is located behind the position of the rear end of the head end part region.

  After that, when the head holder 20 is rotated clockwise or counterclockwise by 90 degrees relative to the head holder 10 (the angle between the two cut surfaces is 180 degrees, an intermediate angle between them). The angle relationship is such that the circumferential surface 10S of the outer periphery of the remaining tip of the tip of the head faces the cut surface 20H of the tip of the tip of the head. Then, the stylus is moved forward (moved in the pulling direction) while maintaining the relative angular relationship. If it does so, it will begin to mutually fit in the predetermined position defined from various dimensions. This state is shown in FIG. With respect to such an angle of rotation to 90 degrees or the like, generally, if a mark is provided on the front side and the rear side pipes and these are combined, the joining operation becomes easier.

  The line indicated by a two-dot chain line 20HA in FIG. 5 which is an enlarged cross-sectional view taken along the arrow line EE is a cut surface when the arrow line EE indicating the cross-sectional position is near the tip of the head portion This is a line indicating 20H. As it is clear if the position difference in the radial direction between the line 20HA and the solid cut surface line 20H corresponding to the position of the current line of sight EE is recognized, the more the tip 10 is pulled out, the more the tip. Each circumferential part surface 10S on the outer periphery of the base part of the heel is strongly pressed against the cut surface 20H of the head end part of the head and the fitting force is increased. That is, the same fitting state as that of the conventional swing-out type joining portion is produced.

  In order to separate the head rod from the head holding rod from this state where it can be fished, the tip rod is pushed into the rod holding rod to release the fitting, and is rotated by 90 degrees in either direction and pulled out. Thus, for example, even if the top guide is a fixed type and the tipper can not be removed from the rear end of the head holder, for example, it is possible to replace the head with a different tip. Become.

  In the above embodiment, the cut surface is a flat surface, but the surface is not limited to a flat surface, and a curved surface having a curvature smaller than the curvature of the outer peripheral portion or inner peripheral portion of each portion (the outer peripheral portion or inner peripheral cylindrical portion of each portion). If the curvature is positive, the curvature can be a negative value (that is, including a concave curved surface). In addition, as described above, there are other variations of the longitudinal shape of the outer peripheral surface 10S of the base portion 10A and the inner peripheral surface 20S of the tip portion 20A. In the following, the case where there are three and four cut surfaces will be briefly described with reference to the drawings. However, there are cases where the number of cut surfaces is one or more.

  7 and 8 show an example of the case where there are three cut surfaces, FIG. 7 is a view corresponding to FIG. 6, FIG. 8 (a) is a perspective view of the front side duct, and (b) is an end face. FIG. Also in this example, the inner peripheral cut surface 20H 'of the rear side tube tip 20A' is arranged at an equal angle, and the intervals are 120 degrees. The original original inner circumference 20S is a straight cylinder in this example also in the longitudinal direction. Inside the cylinder, cut surfaces 20H 'are formed at three locations 120 degrees apart. This cut surface is also formed here as a flat surface, and approaches the center of the ridge as it goes in the forward direction of the tip portion 20A '. That is, as shown in FIG. 7A, the distance (in the radial direction) from the central axis is shorter toward the front side. Therefore, this cut surface has a trapezoidal shape with a wide front side and a narrow rear side, or isosceles triangle shape.

  Further, the outer peripheral cut surface 10H 'of the base portion 10A' of the front side pipe 10 'is also arranged at an equal angle with an interval of 120 degrees. Also in this example, the basic circular outer periphery 10 </ b> S is a front conical shape. Planar cut surfaces 10H 'are formed at three positions on the side of the conical cylinder by milling. This cut surface is formed in parallel to the central axis of the front side tube, and as a result, it becomes a trapezoidal shape with a wide rear side and a narrow front side, or an isosceles triangle shape.

  Accordingly, when the front side tube tube base portion 10A 'is inserted into the rear side tube tube tip portion 20A', the cut surface 10H 'is set at an angular position facing the cut surface 20H' of the front portion 20A '. That is, as shown in (b), the circumferential portion surface 10S on the outer periphery of the original portion, which is a part of the original conical cylinder surface 10S divided into three portions by the formation of the cut surface, It is set as the angular position which can face the circumferential part surface 20S of inner periphery of the front part. The base portion 10A 'is formed in various diameters that can be inserted into the front portion 20A' in this relative angle state.

  After fully inserted, the circumferential surface 10S of the outer periphery of the base portion at an angular position corresponding to the circumferential surface 20S of the inner periphery of the front side of the rear side tube is adjacent to the circumferential surface 20S of the inner periphery of the front portion. If it is rotated in any direction about 60 degrees (half of the aforementioned 120 degrees) so as to be able to face the cut surface 20H ′, the circumferential surface of the outer periphery of the three base portions 10S is an angular position at which it can face the cut surface 20H ′ at the front part. Therefore, if the front side pipe is pulled out while maintaining this relative angular position, each cut surface 20H ′ of the tip portion is inclined so as to approach the center toward the front side, and thus fitted in the middle (each such Designed to radial dimensions, this design itself is easy for those skilled in the art).

  9 and 10 show an example of the case where there are four cut surfaces, FIG. 9 is a view corresponding to FIG. 6, FIG. 10 (a) is a perspective view of the front side duct, and FIG. 9 (b) is an end view. It is. Also in this example, the inner peripheral cut surface 20H ″ of the tip portion 20A ″ of the rear side tubule is arranged at an equal angle, and the intervals are 90 degrees. The original tip inner circumference 20S that is the basis is also a straight cylinder in this example. Inside the cylinder, cut surfaces 20H ″ are formed at four locations 90 degrees apart. This cut surface is also formed here as a flat surface, and in the forward direction of the front portion 20A ″, the center of the ridge is formed. It is approaching. That is, as shown in FIG. 9A, the distance from the central axis (in the radial direction) is shorter toward the front side. Therefore, this cut surface has a trapezoidal shape with a wide front side and a narrow rear side, or isosceles triangle shape.

  Further, the outer peripheral cut surface 10H ″ of the base portion 10A ″ of the front side pipe 10 ″ is also arranged at an equal angle of 90 degrees. Also in this example, the basic circular base portion outer periphery 10S has a front fine cone shape. A flat cut surface 10H ″ is formed by four milling operations on the four sides of the conical cylinder. This cut surface is formed in parallel to the central axis of the front side tube, and as a result, it becomes a trapezoidal shape with a wide rear side and a narrow front side, or an isosceles triangle shape.

  Accordingly, when the front side tube tube base portion 10A ″ is inserted into the rear side tube tube tip portion 20A ″, the cut surface 10H ″ is set at an angular position facing the cut surface 20H ″ of the tip portion 20A ″. If it is rotated in either direction by about 45 degrees (half of the above 90 degrees) and the front side tube is pulled out at the angular position, it fits in the middle (designed to such dimensions).

  A form in which five or more cut surfaces are provided is also possible. Furthermore, the form which provides one place is also possible, and unlike FIG. 11, it is a case where a cut surface is a spiral shape, and it is explanatory drawing in the case of one place. A cut surface 10H ″ ″ is formed in a spiral shape in the direction of an angle θ with respect to the longitudinal direction of the soot tube on the outer periphery 10S having a circular cross section of the front side soot tube base portion 10A ″ ″. On the other hand, one cut surface 20H ′ ″ is formed in a spiral shape in the direction of the angle Θ with respect to the longitudinal direction of the soot tube, as shown in the figure, in the front portion 20A ′ ″ of the rear soot tube. Yes. Both angles θ and Θ are substantially the same. This figure shows a state in which both cut surfaces are angularly coincident, and while starting to insert the base portion 10A ′ ″ at the entrance of the front portion 20A ′ ″ while maintaining this relative angular relationship, the front side along the spiral direction is shown. By inserting the soot tube while twisting it, it enters the inside, and after that, for example, if it is rotated 180 degrees and it is going to be pulled out, it can be fitted tightly on the way. A plurality of cut surfaces can be provided.

  12 to 14, as shown in FIG. 6 and the like of the first embodiment, the cut surface 20 </ b> H in the rear side tube tip 20 </ b> A gradually approaches the center of the rod over its entire length. In the range of the inclined region L2 near the rear end of the cut surface 20H "" in the rear side tube tip portion 20A "", the front side gradually approaches the center of the rod, but in other regions, the center axis The form parallel to is illustrated. In this case, four cut surfaces are provided at intervals of 90 degrees. On the other hand, in the region L1 near the rear end, the front side tub tube base portion 10A "" is provided with cut surfaces 10H "" at four locations at intervals of 90 degrees on the truncated cone 10S as in the first embodiment. ing. This cut surface is provided in parallel to the central axis of the ridge, so that the cut surface is triangular.

  As for the joining method, the front side tube can be inserted at the relative angular position shown in FIG. 12, and if it is sufficiently rotated after being inserted by 45 degrees and pulled to the front side, the inclined region L2 in the joint region of the rear side tube. In the range, the region L1 portion (the circumferential surface 10S of the truncated cone that is partially cut) in the joining region of the front side tube can be tightly fitted (set to such a dimension). This is the same as the other embodiments. Such an example is possible even when there are other than four cut surfaces. Further, as can be seen from FIG. 13, the remaining area of the front side tubule base is a cylinder 10S 'whose radius is the distance from the central axis of the front vertex of the triangle. If this radius is designed so as to substantially coincide with the radius of the inscribed circle on the four sides of the inlet of the rear side tube tip portion shown in FIG. 4, it is difficult to rattle in the joined state.

  The various modifications described in the first first embodiment in which two cut surfaces are provided are the same in the other embodiments unless there is a particular contradiction, and there are various modifications within the scope of the claims.

  The present invention can be applied to a joint type fishing rod. In particular, the present invention can be suitably applied to a swing-out joint type fishing rod having a fishing line guide attached to the outside and having a fishing line guide fixed to the tip of the rod pipe. However, the present invention can also be applied to other joint type fishing rods that have been joined together in a conventional manner.
