This invention is a state which accommodates a small diameter side pole in a large diameter side pole, and switches the state of the small diameter side pole to the state which extracted the small diameter side pole from the large diameter side pole from the storing state, and the extracted extended state It relates to a pull-out pole for installing a joint to maintain the.

Composed in such a manner as to constitute the above-mentioned joint portion in contact with the outer circumference of the pole-end pole side end of the small diameter side pole and the inner circumferential surface of the pole-end side side end of the large diameter side pole in contact with each other. The inclined surface is formed. The inclined surfaces of the inclined surfaces maintain the elongated state of the small diameter side pole.

In the case of adopting the configuration for maintaining the elongated state of the small diameter side pole in the crimping state as described above, when water or the like enters the crimping contact surface, a so-called fixed state appears. That is, even when the small diameter side pole is to be returned from the stretched state to the contracted state, since both inclined surfaces are strongly adhered at the pressure welding site, even if the normal return force is applied, the stretched state cannot be released. Occurs.

Therefore, in this case, the pole cannot be stored, and the end is troubled.

In view of this point, a small protrusion is formed on the outer circumferential surface of the rear end of the small diameter pole tube as the small diameter side pole and press-contacted with the inner circumferential surface of the tip of the large diameter pole tube as the large diameter side pole, and water is formed between the inner and outer peripheral surfaces. There existed a structure which forms a discharge path so that it may not enter (refer patent document 1).

<Patent Document 1> Japanese Utility Model Registration Publication No. 2569413 (Paragraph No. [0009] [0012], Fig. 1)

Certainly, it can be said that the adhesion phenomenon is promoted when moisture enters the joint portion, but it is thought that the adhesion phenomenon is not only its cause. That is, as shown in the above-mentioned prior art, the seam is caused by the inclined inner peripheral surface formed on the pole tip end side of the large diameter side pole and the inclined outer peripheral surface formed on the pole base end side of the small diameter side pole. When both inclined surfaces are pressed, the pole end opening of the large diameter side pole receives the force in the extending direction, and the pole proximal end of the small diameter side pole receives the contracting force and is elastically deformed with each other. Done. Therefore, since the pressure welding is performed in an elastically deformed state, it becomes a stronger bonding state and it is difficult to return to the original state.

The state of the art in which the pressure contact state is achieved in the state in which the protrusion is pressed against the inclined surface of the other side is also considered to be no exception. Compared with not forming a small protrusion, even if it is the structure which is hard to fall into a sticking phenomenon, when the joint operation was performed, it did not eliminate the point which becomes a press contact state at the moment, and further improved the joint part.

An object of the present invention is to provide a rod for fishing rods capable of avoiding the above-mentioned drawbacks and reducing the production burden while avoiding the stuck state.

〔Configuration〕

The characteristic constitution of the invention according to claim 1 is to form a joint portion for holding the small diameter side pole in an extended state with respect to the large diameter side pole, and the joint portion is formed on one pole of the small diameter side pole and the large diameter side pole. The contact surface is composed of a straight cylindrical portion having a constant diameter, and a protrusion formed on the other pole of the small diameter side pole and the large diameter side pole and in contact with the contact surface of the straight cylindrical portion. A surface layer in contact with the protruding portion of the prepreg having a reinforcing fiber group mixed and disposed along a predetermined inclination angle with respect to a pole axis, and a state of being symmetrical with respect to the reinforcing fiber group of the prepreg and the pole axis The prepreg having a group of reinforcing fibers arranged and mixed with each other; And a surface layer in contact with the cylindrical section rate, the points that make up the resin in the groups of reinforcing fibers are arranged along the axial direction of the mixing rod to the impregnation (含浸) that prepreg, the functions and effects are as follows.

〔Action〕

By forming a straight cylindrical portion on one of the joint portions, even when the pull-out operation is carried out abruptly, a state in which the protrusion and the straight cylindrical portion are in contact with each other appears, so that the operating force is alleviated by the operation resistance at the protrusion and the straight cylindrical portion. At the same time, since the constant resistance to resistance is continued due to the presence of the straight cylindrical portion, the angler is also recognized by the angler and rarely falls into a stuck state.

Moreover, since the protrusion part which consists of prepregs is employ | adopted as the counterpart side which contacts a straight cylindrical part, the counter force to abrasion etc. is strong compared with forming the small protrusion by resin etc.

However, the prepreg containing reinforcing fibers is not simply formed, and since the mixing direction of the reinforcing fibers is set in the direction along the pole axis, it is easier to bend and deform than when the reinforcing fibers are mixed in the circumferential direction. It is. For example, when the cross section of the pole is to be deformed in an ellipse shape, when the reinforcing fibers are arranged in the circumferential direction, the cross section becomes difficult to deform from the point that the reinforcing fibers exert a counter force and try to prevent deformation. On the other hand, the reinforcement fibers mixed and arranged in the long axis direction do not have a large strain preventing force when the cross section is deformed in an ellipse, compared with the case where the reinforcing fibers are arranged in the circumferential direction. This means that the protrusions tend to bend in the radial direction, so that when the protrusions move in contact with the straight cylindrical portion, the protrusions cause some bending, so that the protrusions and the straight cylindrical portion are in strong contact with each other. Avoided. As a result, when the small diameter side pole is pulled out from the large diameter side pole, the extraction resistance becomes stable.

Further, the surface layer of the straight cylindrical portion has a prepreg having a group of reinforcing fibers mixed and disposed along a predetermined inclination angle with respect to the pole axis, and a reinforcement mixed and arranged in a symmetrical state with respect to the reinforcing fiber group of the prepreg and the pole axis. Since the prepregs having the fiber groups are formed so as to overlap each other, even when a shearing force or the like inclined in the axial direction is applied, the reinforcing fibers arranged in the inclined state exert an opposing force, and the resin foil It is possible to prevent plastic deformation and the like of the lining and the joint portion.

And since the surface layer of a straight cylindrical part is arrange | positioned in the state which inclined the direction of the reinforcing fiber with respect to the pole axis, the cross section is easy to deform | transform as mentioned above compared with the case where the reinforcing fiber is arrange | positioned in the circumferential direction, In addition to the fact that the reinforcing fibers are mixed and arranged along the long axis direction as described above, they are easy to deform, and even when the straight cylindrical portion and the protruding portion are formed in a state deviated from a predetermined dimension, The following dimension absorbency is good, and the contact state of a straight cylindrical part and a protrusion part can provide stable contact resistance even if a deformation | transformation arises in at least one, and can make a pull out resistance constant.

In addition, since both have a structure which is easy to deform, excessive stress does not act, and peeling of the resin and plastic deformation can be suppressed.

〔effect〕

Therefore, the point which forms a straight cylindrical part, the point which contacts the straight cylindrical part in the shape of a protrusion part, the point which forms a protrusion part by a prepreg, the point which mixes the reinforcement fiber of the prepreg along the long axis direction, and the straight By modifying the point where the cylindrical portion is formed into the prepreg and the reinforcing fiber of the prepreg in a state inclined in the direction of the long axis, the separation of the resin and the plastic deformation can be suppressed, It was prevented beforehand, and the operation feeling at the time of extracting the small diameter side pole from the large diameter side pole and performing a joint operation was able to be improved.

A characteristic configuration of the invention according to claim 2 is to form a conical inclined support surface in the state adjacent to the pole tip of the straight cylindrical portion on the inner circumferential surface of the large diameter side pole, and the small diameter side pole The conical inclined contact surface which contacts the said inclined support surface on the outer peripheral surface is formed, The effect is as follows.

[Action effect]

In the final stage where the contact between the protrusion and the straight cylindrical portion is continued, the inclined contact surface comes into contact with the inclined support surface. That is, a substantially constant tensile resistance is sensed in the state where the protruding portion contacts the straight cylindrical portion. In the case where this substantially constant tensile resistance is in operation, when the inclined contact surface comes into contact with the inclined support surface, suddenly, the tensile resistance increases, and the large resistance is detected by the angler, and it can be detected that the positive end position has been reached. have.

Thereby, it can prevent to pull out too much in advance, and can prevent that a sticking phenomenon appears.

The characteristic constitution of the invention according to claim 3 includes a prepreg having a reinforcing fiber group in which the inclined support surface and the surface layer of the inclined contact surface are mixed and arranged along a predetermined inclination angle with respect to a pole axis, and the reinforcing fibers of the prepreg. The prepreg which has a group and the reinforcement fiber group mixed and arrange | positioned in the state which becomes symmetrical with respect to the said pole axis line is comprised, and the effect is as follows.

[Action effect]

There is an effect similar to the invention according to claim 1 or 2. In addition, it has the following effects. That is, when the extraction operation from the large diameter side pole of the small diameter side pole continues further in the state which the protrusion part and the straight cylindrical part contact and the state is maintained, the inclined support surface and the inclined contact surface contact, and the extraction state is carried out. Is stopped.

In this case, the prepreg having the reinforcing fiber group in which the inclined base surface and the surface layer of the inclined contact surface are mixed and arranged along a predetermined inclination angle with respect to the pole axis, the reinforcing fiber group of the prepreg and the symmetry with respect to the pole axis. Since the prepreg having the group of reinforcing fibers mixed and arranged in a superimposed state is configured to overlap, the reinforcing fibers are inclined with respect to the pole axis and the circumferential direction as well as the tensile force acting in the pole axis direction and the circumferential direction. Since a counter force is exhibited also about the shear force along a direction, peeling of resin and plastic deformation of a joint part can be suppressed.

Furthermore, since the reinforcing fibers are arranged in a state inclined in the circumferential direction as compared with the arrangement of the reinforcing fibers in the circumferential direction, they are easy to bend and are excellent in dimension absorbency. There is no strong tightening, and it can suppress that it falls in a sticking phenomenon.

The characteristic constitution of the present invention according to claim 4 is to form a pole proximal end on a pole proximal side of the inclined contact surface on an outer circumferential surface of the small-diameter side pole, and to install the protruding portion on the pole proximal end of the pole proximal end. The outer diameter at the proximal end is set to a smaller diameter than the outer diameter of the long proximal end of the inclined contact surface and the outer diameter of the protruding portion, and the effect thereof is as follows.

[Action effect]

In other words, in the state where the protruding portion contacts the straight cylindrical portion, the outer circumferential surface of the pole proximal end does not contact the straight cylindrical portion or the inclined support surface from the point that is smaller than the outer diameter of the proximal proximal end of the inclined contact surface or the outer diameter of the protruding portion. Therefore, in the state where the small diameter side pole is pulled out from the large diameter side pole, only the protrusion formed in the pole base end of the pole base end part contacts the straight cylindrical part until the inclined contact surface contacts the inclined support surface. Since it is in the state, even if the direction of extraction is inclined to some extent with respect to the pole axis, the contact state with the straight cylindrical portion due to the inclination state can be adjusted by the deformation of only the protrusion, Improves the operability.

In addition, since the long base end portion that supports the protruding portion at the long proximal end position is a small diameter, the cross-sectional coefficient decreases, and the long proximal end portion is connected to the inclined contact surface by the reaction force received from the straight cylindrical portion that contacts the protruding portion. As the proximal end, the protruding portion positioned on the pole proximal side is easily displaced in the radial direction like the distal end of the cantilever beam. Therefore, even if there exists a fluctuation | variation in the diameter dimension of a straight cylindrical part, the contact surface of predetermined surface pressure can be maintained by displacement of a protrusion.

A characteristic constitution of the invention according to claim 5 includes a prepreg having a reinforcing fiber group in which the surface layer of the pole proximal end is disposed along a predetermined inclination angle with respect to the pole axis, the reinforcing fiber group of the prepreg and the pole axis. The prepreg which has the reinforcing fiber group mixed and arrange | positioned in the state which becomes symmetrical with respect to is piled up, and the effect is as follows.

[Action effect]

In other words, in the state where the protruding portion contacts the straight cylindrical portion, the outer circumferential surface of the pole proximal end does not contact the straight cylindrical portion or the inclined support surface from the point that is smaller than the outer diameter of the proximal proximal end of the inclined contact surface or the outer diameter of the protruding portion. Therefore, the pole proximal end does not receive direct reaction force from the straight cylindrical portion nor the inclined support surface.

However, the reaction force acting on the protrusion formed on the pole base of the pole base affects the pole base. In this case, the mixed layer is arranged in such a manner that the surface layer of the pole proximal end has a prepreg having a group of reinforcing fibers mixed and arranged along a predetermined inclination angle with respect to the pole axis, and the reinforcing fiber group of the prepreg is symmetrical with respect to the pole axis. Since the prepreg having a group of reinforced fibers are superimposed and configured, the shear force acting from the direction inclined with respect to the pole axis as well as exerting a force against the load acting in the pole axis direction and the load acting in the circumferential direction In addition, the reinforcement fiber arrange | positioned in the state inclined with respect to the said long axis axis | shaft exhibits a counter force, and can improve the counter force to the load from a multi-direction.

Thereby, since the strength of the pole base end part which supports a protrusion part can be raised, the contact state with respect to the straight cylindrical part of a protrusion part is stabilized.

The characteristic structure of this invention concerning Claim 6 forms the inclination guide cylinder part between the said straight cylinder part and the main-body part provided in the pole base end side rather than this straight cylinder part, and the inclination guide surface in the said inclination guide cylinder part. The enlargement degree which enlarges an inner surface diameter along the pole axis direction of is set larger than the cylindrical surface of the said straight cylindrical part, and smaller than the expansion diameter which enlarges an inner surface diameter along the pole axis direction of the inner peripheral surface of the said main body part, The effects are as follows.

[Action effect]

That is, since the inclined guide cylinder is provided, even when the protrusion is located at the main body portion, the protrusion is eccentric with respect to the pole axis, and the position difference is caused with respect to the straight cylinder, Before the contact with the straight cylindrical portion, the projection is guided along the inclined surface of the inclined guide cylinder portion, and the enlarged diameter of the inclined guide surface of the inclined guide cylinder portion is larger than the cylindrical surface of the straight cylindrical portion, and also the enlarged diameter of the inner circumferential surface of the pole body portion. Since the setting is made smaller, the protruding portion is guided to correct the position difference of the straight cylindrical portion.

Therefore, since the contact state of a protrusion part and a straight cylindrical part is adjusted to a constant pressure contact state, the operation which pulls out a small diameter side pole from a large diameter side pole can be performed easily.

The characteristic constitution of the invention according to claim 7 includes a prepreg having a reinforcing fiber group in which a surface layer of the inclined guide tube portion is mixed along a predetermined inclination angle with respect to a pole axis, a reinforcing fiber group of the prepreg and the pole axis. The prepreg which has a group of reinforcing fibers mixed and arranged in a symmetrical configuration with respect to is superimposed, and the effect is as follows.

[Action effect]

That is, when the protrusion is guided and moved to the inclined guide tube, the direction of the load exerted on the inclined guide surface is not only orthogonal to the inclined guide surface, but also acts in the inclined state, thereby forming a complicated load action form. On the other hand, the surface layer of this inclined guide tube part is a prepreg which has the reinforcement fiber group mixed and arrange | positioned along the predetermined inclination angle with respect to the pole axis, and the state which becomes symmetrical with respect to the reinforcement fiber group of the said prepreg, and the said pole axis. Since the prepregs having the group of reinforcing fibers mixed and arranged are overlapped and configured, the reinforcing fibers exert an opposing force against loads acting from multiple directions and rarely cause peeling or plastic deformation of the resin.

In addition, since the reinforcing fibers are arranged in the inclined state in this way, the flexibility is higher than that in the circumferential direction, and no sticking phenomenon occurs.

<Examples>

[First Embodiment]

The structure mainly applied to the intermediate pole on the large diameter side, especially from the pole 4 and the like, in the intermediate zone from the pole 2 to the original pole in the pull-out pole A will be described. The pole on the small diameter side will be described as the small diameter side pole 1, and the pole on the large diameter side will be described as the large diameter side pole 2.

In addition, although city is not shown, pole is produced as follows. That is, reinforcing fibers such as carbon fibers are mixed in one direction, and the mixed reinforcing fiber group is impregnated with a thermosetting resin (or thermoplastic resin) such as epoxy to form a prepreg. The prepreg was cut into a mandrel, wound into a mandrel, fired to form a plurality of layers, cut into a predetermined length after firing, and finished with a finish. do.

As the reinforcing fibers constituting the prepreg, glass fibers, aramid fibers, alumina fibers and the like can be used in addition to carbon fibers. Thermoplastic resins such as phenol resins and polyester resins and thermoplastic resins such as PET can be used as the resin.

The structure of the small diameter side pole 1 is demonstrated. As shown in Fig. 1 (a), the small diameter side pole 1 is formed on the outer circumferential surface of the pole proximal end and has a conical inclined contact surface 1A which is largely hardened by the pole proximal side, and the inclined contact surface ( The pole base end part 1B which shows a slightly inclined state (or maintains the same diameter) is provided in the pole base end side of 1A), and the protrusion part 1a is provided in the pole base end of the pole base end part 1B.

As shown in Fig. 1 (c), the protrusion 1a is provided at three places in the circumferential direction, and is formed of a prepreg similarly to the pole 1. That is, as shown in FIG. 2, the group of reinforcing fibers (c) in which the surface layer in contact with the straight cylindrical portion 2B to be described later of the protrusion 1a is mixed and arranged along the axial direction of the small diameter side pole 1. It consists of the prepreg in which resin was impregnated.

The structure in the surface layer in the inclined contact surface 1A and the pole base end part 1B is demonstrated. As shown in FIG. 2, the mixing direction of the reinforcing fiber c in the prepreg in the inclined contact surface 1A and the pole base end part 1B is arrange | positioned in the state along the pole circumferential direction. . By the structure of excretion of the reinforcing fibers (c), the reinforcing fibers (c) exert an opposing force against the fact that the cross section of the rod becomes horizontally wide and elliptical, thereby preventing the rod from being damaged by being elliptic.

The manufacturing process of the small diameter side pole 1 which consists of the above structures is put together as follows. As shown in FIG. 3, the mandrel 6 is wound around a plurality of main patterns 3 obtained by cutting the prepreg to a length corresponding to the entire length of the small diameter side pole 1. Here, the inner main pattern 3A, the middle main pattern 3B, and the outer main pattern 3C are respectively circumferential directions orthogonal to the pole axis X, directions along the axis X, It is wound in the circumferential direction. The intermediate reinforcement pattern 7 is wound around the pole proximal end of the pole material C formed by winding the main pattern 3. The intermediate reinforcement pattern 7 includes a prepreg 7A having a group of reinforcing fibers c mixed and disposed along a predetermined inclination angle θ with respect to the pole axis X, and the reinforcing fibers c of the prepreg 7A. ) And a prepreg 7B having a group of reinforcing fibers (c) arranged in a symmetrical manner with respect to the group and pole axis (X).

The prepreg tape 16 is wound on the outer layer side of the intermediate reinforcement pattern 7. That is, the prepreg tape 16 formed in the narrow circumferential direction by arranging the group of reinforcing fibers c is closely wound in a state where the tapes do not overlap and in contact with each other to form an intermediate layer. The outer reinforcement pattern 8 as a surface layer is wound on the outer peripheral surface of the pole base end position of the pole material C which wound this prepreg tape 16. As shown in FIG. The outer reinforcement pattern 8 is a wide reinforcement pattern 8A and a narrow reinforcement pattern which mixes a group of reinforcing fibers c along the pole axis direction in a shorter width than the wide reinforcement pattern 8A. It consists of 8B. The prepreg constituting the wide reinforcement pattern 8A includes a portion 8a forming the inclined contact surface 1A and a portion 8b forming the pole proximal end 1B. The part 8b which forms the pole base end part 1B in the wide reinforcement pattern 8A is cut | disconnected in substantially triangular shape, and the pole base end part which becomes smaller diameter than the inclined contact surface 1A by winding in multiple fry | wires ( 1B). In this manner, the pole proximal end 1B is formed, and since a substantially triangular reinforcement prepreg is used, the pole proximal end 1B is easy to be hardened and deformed as much as the pole proximal side forming the protruding portion 1a. To form.

The structure of the large diameter side pole 2 is demonstrated. As shown in Fig. 1 (a), the inclination degree (about 3.0 / 1000) smaller than the normal expansion degree (about 5/1000) of the place where the inner circumferential surface of the inclined support tube portion on the pole tip side is largely hardened by the pole base end side. In addition to forming the inclined support surface 2A, which is indicative of the shape, the inner surface diameter is maintained at the same or approximately the same diameter (about 0.3 / 1000) toward the longer proximal end from the longer proximal end of the inclined support surface 2A. Magnification (about 2.55 / 1000) that forms a straight cylindrical portion 2B and is slightly smaller than the enlarged diameter of the inclined support surface 2A from the pole end of the straight cylinder 2B toward the pole pole end over a certain length. The inclined guide tube portion having the inclined guide surface 2C is provided, and furthermore, the main body portion 2F having a general inclination (about 5/1000) as a pole is formed on the pole base end side than the inclined guide surface 2C.

As described above, the joint portion B is constituted by the inclined contact surface 1A, the protruding portion 1a, the inclined support surface 2A, and the straight cylindrical portion 2B of the small diameter side pole 1.

An inner circumferential surface layer is formed as a surface layer in the range spanning the inclined support surface 2A, the straight cylindrical portion 2B, and the inclined guide surface 2C in the large diameter side pole 2, as shown in FIG. Is constituted by the inner reinforcement pattern 9. The inner reinforcement pattern 9 has a prepreg 9A having a group of reinforcing fibers c mixedly arranged along a predetermined inclination angle θ with respect to the pole axis X, and the reinforcing fibers c of the prepreg 9A. ) And a prepreg 9B having a group of reinforcing fibers (c) arranged in a symmetrical manner with respect to the group and pole axis (X). Thus, by arrange | positioning a group of reinforcing fiber c by a bias, the counter force to the load applied from the direction which inclines with respect to the pole axis line X can be raised, and the strength as the joint part B can be improved.

With respect to the mandrel 6 which applied the inner reinforcement pattern 9, three main patterns 3A, 3B, and 3C are wound sequentially, and the skeleton as a pole material C is formed. Although illustration is abbreviate | omitted about the process after winding the main pattern 3, as shown in FIG. 3 mentioned above, the prepreg tape on the outer layer side of the intermediate reinforcement pattern 7 and the intermediate reinforcement pattern 7 is shown. The outer reinforcement pattern as the surface layer is wound on the outer circumferential surface of the pole proximal end position of the pole material C formed by winding the 16 and the prepreg tape 16. As the outer reinforcement pattern, a wider reinforcement pattern 8A of the outer reinforcement pattern 8 shown in Fig. 3 is selected, and the prepreg having the reinforcing fibers c arranged in the circumferential direction without using the narrow reinforcement pattern 8B. It consists of one piece of leg.

When the small diameter side pole 1 is accommodated in the large diameter side pole 2 and pulled out in the extended state by the above structure, first, the protrusion 1a is brought into contact with the inclined guide surface 2C and guided. At the same time, it moves from the inclined guide surface 2C to the straight cylindrical portion 2B and inscribes the straight cylindrical portion 2B. While continuing the pull-out operation of the small-diameter side pole 1, the protrusion 1a inscribes the straight cylindrical portion 2B, imparts a pull-out resistance suitable for the pull-out operation, and gives the angler the seam B Can recognize that the registration has started.

Then, if the extraction operation is further performed, as shown in Fig. 1 (b), the inclined contact surface 1A finally comes into contact with the inclined support surface 2A, and thus suddenly reaches the small diameter side pole 1. The large pull-out resistance acts, and this makes it sense to the angler who pulls out the small diameter side pole 1, and it is suppressed that the small diameter side pole 1 is pulled out further.

On the other hand, the pole proximal end 1B is smaller than the pole proximal end diameter of the inclined contact surface 1A and the diameter of the protruding portion 1a, and therefore the pole proximal end 1B does not contact the straight cylindrical portion 2B. In other words, the extraction resistance is not excessive.

As the structure of the above-mentioned joint part B, the above-mentioned fixation prevention effect is also high, and the test data which demonstrated the effect is shown in Table 1. As shown in FIG. The test apparatus which obtains the data of Table 1 is shown in FIG. 5, The small diameter side pole 1 is fitted to the large diameter side pole 2, and the small diameter side pole 1 is suspended and supported. The fitting force of the small diameter side pole 1 and the large diameter side pole 2 is initially set to 5 kg.

Movement amount L of the large diameter side pole 2 in the state which dropped the weight Wh from the height H with respect to the large diameter side pole 2, and received it with the support flange 2D formed in the large diameter side pole 2 The data is measured.

The movement amount L is measured by changing the fall amount of the weight Wh from 50 mm to 150 mm in steps, and it is measured whether it is possible to return to the initial state before dropping the weight Wh = 1 Kg from the moving state. . That is, it is measured whether it is possible to return to the initial state from the moved state of the large diameter side pole 2, for example, whether it is not stuck in the stuck state, and all were not difficult to return to the original state, It can be seen that the seam portion B with less falling out could be provided.

As the rod used for the test, the rod having the straight cylindrical portion 2B of the present invention is used, and as the rod of the conventional product, the seam portion B is formed by spraying a resin coating on the outer peripheral surface of the rear end of the small diameter side pole. The pole which has the part which formed many resin protrusions, and the prepreg which arrange | positioned in the shape of a turtle the thermoplastic resin with higher flexibility arrange | positioned on the pole base end side than that part is used.

◎ ‥‥ No sticking, can be easily returned to the original state

○ ‥‥ Can be returned to its original state

△ ‥‥ Because it is stuck, two people can only return

× ‥‥ Strong fixation cannot be reversed

Using the said drop tester, the required tensile force or return force in a fall distance (50 mm-150 mm) is measured, and the result is shown in Table 1. According to this, in this invention, it is 30 kg or less as a return force in all the fall distances (50 mm-150 mm). Since the range which can be returned by one force is 50 kg or less, it can be judged that fixation does not occur.

On the other hand, in a conventional product, 52 kg is already required as a return force at the fall distance of 130 mm, exceeding the limit which can be returned alone, and the countermeasure against fixation is needed.

The following test was done as showing evaluation in the joint part B of the above-mentioned this invention and the prior art.

In order to measure the movement resistance of the joint portion B of the present invention and the prior art (painted projection), a machine (not shown) is used to measure the movement resistance by applying a tensile force and a return force. Although the measurement result is shown in FIG. 6, according to the result, although the difference of a tensile force and a return force is not remarkable, the difference between this invention and a conventional article is remarkable.

That is, in the present invention, the inclined contact surface 1A is in contact with the inclined support surface 2A after the protrusion 1a is brought into contact with the straight cylindrical portion 2B to impart resistance, so that the small diameter side pole ( The stroke until the extraction condition of 1) stops is about 26 to 27mm.

In contrast, in the above-described conventional products, contact is started from a position corresponding to 10 mm in the present invention, and the resistance gradually increases, and at about 26 to 27 mm at the end of the stroke, the movement resistance is 2-3 times higher than that of the present invention. It will be shown that the stuck state.

Here, in the case of verifying the case of the present invention in detail, the movement resistance is maintained at a constant resistance of about 3 kilos from about 10 mm to about 22 mm of the stroke. This constant resistance portion can be considered to be a portion indicated by maintaining the state in which the protrusion 1a is in contact with the straight cylindrical portion 2B, and can be evaluated as a feature of the present invention. Based on the above evaluation results, it is recognized that the present invention is excellent also in the fixation measures.

[Second embodiment]

Here, in the pole base end part of the small diameter side pole 1, although the installation number of the protrusion surface part 1a is arbitrary, the structure which arrange | positioned four protrusion surface parts 1a in four circumferential directions is shown in FIG.

In this way, even when only the protrusions 1a are formed, the anglers by contacting the protrusions 1a over the straight cylindrical portion 2B from the inclined guide surface 2C formed on the large diameter side pole 2 are carried out. It can give a good feeling of operation at the time of joint operation.

[Third Embodiment]

The state which replaced the formation object of a protrusion part and a straight cylindrical part is shown. As shown in Fig. 10 (a), the inclined contact surface 1A is formed on the outer circumferential surface of the pole proximal end of the small diameter side pole 1 as in the case of the first embodiment, and the outer surface diameter is constant on the pole proximal side. The straight cylindrical part 1C is provided.

On the other hand, on the inner circumferential surface of the pole tip of the large-diameter side pole 2, the inclined support surface 2A to which the inclined contact surface 1A comes into contact is formed, and on the pole proximal side of the inclined support surface 2A, A protrusion 2E is formed to protrude to i).

When the small diameter side pole 1 having the above-described configuration is accommodated in the large diameter side pole 2, first, the straight cylindrical portion 1C of the small diameter side pole 1 is the protrusion 2E of the large diameter side pole 2; ). If the extraction operation is continued while maintaining the contact state between the straight cylindrical portion 1C and the protrusion 2E, the inclined contact surface 1A contacts the inclined support surface 2A, as shown in Fig. 10B. As a result, the extraction operation cannot be performed.

[Example 4]

Although the protrusions 1a and 2E are formed as being in contact with the straight cylindrical portion on the opposite side, as shown in Figs. 11A and 11B, the small-diameter side pole 1 is configured as a protrusion. The flange-shaped protrusion 1D may be provided at the end of the pole. That is, the flange-shaped protrusion part 1D is formed, and the outer peripheral surface of the flange-shaped protrusion part 1D is comprised so that it may contact the straight cylindrical part 2B of the large diameter side pole 2. As shown in FIG. In order to elastically contact the straight cylindrical portion 2B of the flange-like protrusion 1D, the divided groove 1d deeply enters the flange-like protrusion 1D over a predetermined length along the radial direction from the outer circumferential surface. May be provided over a plurality of circumferential directions. Thereby, the pressure which contacts the straight cylindrical part 2B of the flange-shaped protrusion 1D can be reduced, and it can be made substantially constant.

[Example 5]

Here, the structure which changed the formation position of a straight cylindrical part and the inclined surface in the long axis direction is demonstrated. As shown in FIG. 12, the straight cylindrical part 1C is formed in the small diameter side pole 1, and the inclined contact surface 1A is formed in the pole base end side. On the other hand, while the projection part 2E is formed in the inner peripheral surface of the pole tip side edge part in the large diameter side pole 2, the inclined support surface 2A is formed in the pole base end side of the projection part 2E, and the joint part ( You may comprise B).

Even in such a configuration, when the small-diameter side pole 1 is pulled out from the large-diameter side pole 2, the straight cylindrical portion 1C of the small-diameter side pole 1 comes into contact with the protruding portion 2E and finally 1 A of inclined contact surfaces contact 2 A of inclined support surfaces, and the elongation state from the large diameter side pole 2 of the small diameter side pole 1 is set.

[Example 6]

Here, in the 4th Example which showed the structure which changed the formation position of the straight cylinder part and the inclined surface in the pole-axis direction, it demonstrates that the object of formation of a protrusion part and a straight cylinder part was changed. As shown in FIG. 13, the straight cylindrical part 2B is formed in the inner peripheral surface of the large diameter side pole 2, and the inclined support surface 2A is formed in the pole base end side. On the other hand, while forming the projection part 1a in the outer peripheral surface of the pole tip side edge part in the small diameter side pole part 1, the inclined contact surface 1A is formed in the pole base end side of the projection part 1a, and the joint part B ) May be configured.

Even in such a configuration, when the small-diameter side pole 1 is pulled out from the large-diameter side pole 2, the straight cylindrical portion 2B of the large-diameter side pole 2 comes into contact with the protruding portion 1a and finally 1 A of inclined contact surfaces contact 2 A of inclined support surfaces, and the elongation state from the large diameter side pole 2 of the small diameter side pole 1 is set.

[Other Embodiments]

(1) As said structure, you may apply to a fishing rod inserted into a pole and let a fishing line pass.

(2) Moreover, as said structure, the handle side pole of a pull-out pole is comprised by the 1st handle side pole as a telescopic large pole, and the 2nd handle side pole as a large diameter side pole of larger diameter than that, and a 1st handle Expansion and contraction which not only form the above-mentioned joint part which press-contacts in the state which pulled out the side pole from the 2nd handle side pole, but also maintains the state in the state which received the 1st handle side pole to the 2nd handle side pole. It may be applied to a pull-out pole.

In this case, it is not necessary to apply the above-mentioned joint part B as a structure which can maintain the state, even if the 1st handle side pole is accommodated in the 2nd handle side pole, The pole of a 1st handle side pole is not required. What is necessary is just to provide and comprise the holding rubber which fits a base end.

(3) As shown in FIG. 9, the notch recessed part 1b which enters concave triangularly toward the pole tip side may be formed in the pole base end opening of the small diameter side pole 1. As shown in FIG. The protrusion 1a and the notch recess 1b are formed at three circumferential directions, and are formed at positions of 120 degrees, respectively.

By forming the notch recess 1b in this manner, the site where the notch recess 1b is formed causes rigid softening due to the notch effect, whereby the long proximal opening is shortened up and down. It is easy to deform into an ellipse that bulges from side to side.

The long proximal end opening receives the contact resistance by the contact of the straight cylindrical portion 2B due to the presence of the notched recess 1b, and the protrusion 1a receives the pressure along the radial direction. This pressure causes deformation in the direction of narrowing the notch width in the notched concave portion 1b, so that even if the pressure fluctuates, the contact resistance does not change significantly.

Thus, since the contact resistance force of the protrusion part 1a and the straight cylindrical part 2B can be made into the state which does not change so much, a feeling of operation improves.

According to the present invention, there is provided a rod for a fishing rod which can avoid a fixing state and reduce a manufacturing burden while avoiding a stuck state.
