Description

  The present invention is a fishing rod constructed by connecting a plurality of rods, and in particular, connecting the rods in a swinging manner so that the rods arranged on the tip side can be sequentially stored in the rods on the rod side. Related to fishing rods.

  Many of the recent fishing rods are used as one long fishing rod by connecting a plurality of rods. One of such methods for connecting the enclosures is called an “emergence format”. In this method, the inner peripheral surface of the tip side end of the large diameter rod located on the heel side is used as the fitting female portion, and the outer peripheral surface of the heel side end of the small diameter rod located on the tip side is fitted to the male. The fitting male part is inserted into the fitting female part and fitted to each other in a state where the small-diameter casing is housed in the large-diameter casing so as to be inserted into and removed from the tip.

  In the case of adopting such a connecting method of the housings called the swing-out type, in order to improve the stability when the housings are fitted and connected to each other, it is necessary to adjust the diameter of the mating portion precisely. However, even if precise adjustment of the diameter is attempted, the fitting portion is worn by repeated use of the fishing rod, the fitting force between the two is reduced, and loosening occurs, which may cause various problems.

  Therefore, various efforts have been made to maintain such a fitting force between the frames. For example, in order to avoid wear of the fitting portion due to repeated use and maintain the fitting force over a long period of time, it is conceivable to improve the wear resistance of the fitting portion. For example, a technique for laminating a polyester-based prepreg material or the like on a fitting portion has been proposed (see Patent Document 1).

Furthermore, another problem associated with such a decrease in the fitting force is that when the small-diameter housing is to be stored in the large-diameter housing, the small-diameter housing is suddenly dropped into the large-diameter housing. Sometimes. Therefore, when a pressing portion is formed on the inner peripheral surface of the base side of the fitting portion of the large diameter casing located on the base side, and a small diameter casing is to be stored in the large diameter casing, A technique or the like has been proposed in which the fitting portion of the small-diameter casing hits the pressing portion and the small-diameter casing is not suddenly stored in the large-diameter casing (see Patent Document 2).

  As described above, various development studies have been made on the connection between the fishing rods of the swing type fishing rod. However, if the diameters of the housings are precisely adjusted to improve the fitting force, and the durability and wear resistance of the mating surfaces are improved, the housings are fitted and connected. There is a risk that the operability will be impaired.

  That is, if the fitting part between the skeletons is excessively refined and the fitting force is maintained and maintained, the small diameter skeleton is pulled out toward the tip of the large sized skeleton so as to fit the skeletons suddenly. Both housings are fitted at a certain position. Such a sudden fitting of both does not give the user a predictability as to when the fitting between the casings occurs. A user who cannot give a predictability may pull out the small-diameter casing from the large-diameter casing vigorously during the fitting operation, and may cause both to be excessively fitted and fixed.

  In addition, when releasing the fitting between the casings, it is not possible for the user to predict whether the fitting between the casings is released at any point in time. For this reason, the user may forcefully push the small-diameter casing into the large-diameter casing during the fitting release operation, and may damage the casing.

  In this regard, according to the technique of the above-mentioned Patent Document 2, it seems that the problem in the fitting release operation can be solved. However, the technique of the above-mentioned Patent Document 2 merely suppresses a sudden drop of the small-diameter casing into the large-diameter casing at the pressing portion not involved in the fitting portion, and in the fitting and releasing operations of the casings, It does not give the user predictability. Moreover, the said part is not concerned at all with respect to the fitting between the casings, and does not attempt to improve the stability of fitting between the casings or the fitting operability.

  The present invention provides a fishing rod that enables smooth fitting and disengagement of rods of the swing-out type, and also enables long-term maintenance of the fitting force.

The fishing rod of the present invention has a first housing having a fitting female portion on the inner periphery of the tip side end portion, and a fitting male portion on the outer periphery of the tip side end portion. And a second housing connected in a form. The fitting female portion on the inner circumference of the tip end portion of the first housing has a tapered female portion whose diameter increases toward the base side in the axial length direction formed on the tip side, and a base side of the tapered female portion. And a straight female portion that is formed in at least a part of the circumferential direction adjacent to the shaft and has an inner diameter that does not change in the axial length direction. In addition, the fitting male part on the outer periphery of the base side end of the second housing includes a tapered male part that can be fitted to the tapered female part formed on the tip side, and a straight disposed adjacent to the tapered male part. A contact member capable of contacting the female portion. The entire outer peripheral surface of the contact member is adjusted so as to contact the straight female portion. Then, when the second casing is pulled out from the first casing, the contact member of the fitting male part comes into contact with the straight female part of the fitting female part , and the tapered female part and the tapered male part are fitted. In the meantime, both are in continuous contact.

  In this fishing rod, when the second rod is pulled out from the first rod toward the tip, first, the straight female portion of the fitting female portion of the first rod contacts the contact member of the fitting male portion. . The straight female portion of the fitting female portion is a region where the inner diameter does not change in the axial length direction, and continuously produces a relatively inexpensive fitting force as the second casing is pulled out. Thereafter, the taper female part of the fitting female part of the first housing and the taper male part of the fitting male part come into contact with each other, and both produce a sufficient fitting force in a state in which both tapers coincide. When the second housing on the tip side is accommodated in the first housing and the fitting between the two is released, conversely, first, the tapered female portion and the fitting male of the fitting female portion of the first housing are firstly provided. The contact with the tapered male part of the part is released. Also in this case, the straight female portion is continuously fitted or abutted on the abutting member for a while, and both the casings slide smoothly to produce a relatively inexpensive fitting force.

  By fitting the housings through such a process, the user can foresee in advance that the housings are completely fitted and their positions are fixed during operation, and this operation can be performed smoothly. It will be. That is, the fitting force can be generated in a shock-absorbing manner before the strong fitting force is generated. However, when both the housings are completely fitted, the contact portion and the straight female portion also produce a constant fitting force, and the stability when the housings are fitted is also improved. On the other hand, when releasing the fit, the user can similarly predict the release of the strong fit, and the operation can be smoothly performed.

  In the fishing rod of the present invention, the fitting male portion on the outer peripheral surface of the second rod body includes a tapered male portion that can be fitted to a tapered female portion formed on the tip side, and a tapered male portion. A straight portion that can be brought into contact with a straight female portion formed adjacent to the straight portion, and the straight portion is an abutting member, and the straight portion extends in the axial direction from the base side edge of the second housing. A split is formed.

  In this fishing rod, the straight portion of the fitting male portion is continuously fitted or in contact with the straight female portion of the fitting female portion in the connection or release operation of the two rod bodies. A split is formed in the straight portion to improve the elasticity in the radial direction, and the straight portion smoothly slides while being fitted to or in contact with the straight female portion. Moreover, excessive wear of both is also prevented. Furthermore, you may apply | coat a lubricant to the outer peripheral surface of the straight part of the fitting male part of a 2nd housing. In this case, excessive wear is prevented, and it is possible to produce continuous contact and fitting between the straight portion and the straight female portion at a low cost.

  In another fishing rod of the present invention, the fitting male portion on the outer peripheral surface of the second rod body includes a tapered male portion that can be fitted to a tapered female portion formed on the tip side, and a tapered male portion. And an elastic body that can enter and exit in the radial direction is disposed on the peripheral surface of the fitting male portion of the outer peripheral surface on the base side of the second casing. The This elastic body is a contact member. In this case, by using the contact member as an elastic body, excessive wear can be prevented and continuous contact and fitting between the contact member and the straight female portion can be produced at low cost. For example, a concave groove may be formed on the entire circumference of the straight surface of the fitting male portion on the outer peripheral surface of the second casing on the base side, and an elastic body may be accommodated in the concave groove. Further, a groove may be formed on the entire circumference of the straight portion of the fitting male portion on the outer peripheral surface of the base of the second housing, and a rubber ring may be accommodated in the groove. Good. In this case, this rubber ring is an elastic body.

  In addition, you may form the fitting male part of a 2nd housing from the prepreg raw material which impregnated the synthetic resin to the boron fiber or the metal fiber. By using a prepreg using such reinforcing fibers, wear of the fitting male part associated with long-term use can be suppressed.

Another fishing rod of the present invention has a first housing having a fitting female portion on the inner periphery of the tip side end portion, and a fitting male portion on the outer periphery of the tip side end portion, and is freely movable in and out of the first rod body on the tip side. And a second housing connected in a swing-out manner. The fitting female portion on the inner periphery of the tip end portion of the first housing includes a straight female portion whose inner diameter does not change in the axial length direction from the tip end portion formed at least in the circumferential direction, and a straight female portion. And a taper female portion whose diameter increases toward the base side in the axial length direction formed adjacent to the base side of the part. Moreover, the fitting male part of the outer periphery side edge part outer periphery of a 2nd housing is adjacent to the taper male part which can be fitted to the taper female part formed in the collar side, and the tip side of a taper male part And an abutting member capable of abutting on the straight female portion to be disposed . Its to and from the first rod body Yuku drawing the second Sao body contact member Hamagoyu portion comes into contact with the straight female portion of the fitting female part, fitting and the tapered female portion and the tapered male portion Both are in continuous contact until they are worn.

  This fishing rod is also used in the same manner as the above-described fishing rod. At this time, the straight female portion of the fitting female portion of the first housing may be split in the axial length direction from the tip side edge of the first housing.

  According to the fishing rod of the present invention, it is possible to smoothly fit and release the swing-type rods.

[First Embodiment]
One of the fishing rods according to the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the fishing rod is composed of a marine rod 1, a middle rod 2 and a rod rod 3 connected to the head side of the rod 1 in a swinging manner. The casings arranged on the tip side can be sequentially stored in the large-diameter casings arranged on the base side. Note that the number of housings is not limited to this, and can be arbitrarily set. Each casing is a tubular body with a tapered taper formed by firing a prepreg material impregnated with a synthetic resin of reinforcing fibers. A butt plug 4 is detachably attached to the end of the heel 1 on the heel side. By removing the butt plug 4, each skeleton located on the tip side is pulled out from the heel side. Can be removed. Further, a fishing line connecting portion 5 for connecting the fishing line L is formed at the end portion on the tip side of the tip rod 3.

Next, the connecting portion of each housing will be described with reference to the base rod 1 and the middle rod 2 as an example.
(About Genroku 1)
As shown in detail in FIG. 2 and FIG. 3, the main shaft 1 is a tubular body that is tapered so that the diameter of the tip side is reduced as a whole. The inner peripheral surface on the tip side serves as a fitting female portion X for connection with the intermediate collar 2. Specifically, the fitting female portion X is formed continuously from the end edge of the heel 1 to the heel side, and the taper female portion 10 that increases in diameter toward the heel side, and the heel side of the tapered female portion 10. And a straight female portion 11. The straight female portion 11 is a portion whose diameter does not change in the axial length direction.

  The taper female portion 10 is formed in a region extending from an end portion on the tip side of the heel 1 to an axial length of several times the outer diameter on the tip side of the heel 1. The straight female portion 11 is a portion where the inner diameter does not change in the axial direction. The length of the straight female portion 11 in the axial length direction is the same as or slightly shorter than the axial length of the tapered female portion 10 described above. For example, a maroon having such a tapered female portion 10 and a straight female portion 11 is manufactured as follows.

  That is, as schematically shown in FIG. 4, a core material 20 is prepared which has a taper taper over the entire axial length direction and has a portion whose diameter does not change in a certain region on the tip side. In such a core material 20, it is preferable that the end portion on the base side of the portion where the diameter does not change in a certain region on the tip side is a curved surface (see the Z portion in FIG. 4).

A release material or the like is applied to the peripheral surface of the core material 20 as necessary, and the prepreg material 21 is wound. The prepreg material 21 is made by impregnating a synthetic resin after arranging reinforcing fibers such as carbon fibers. As the prepreg material 21, in addition to a sheet-like material as shown in FIG. 4, a prepreg material processed into a tape shape is used in combination. In particular, an auxiliary prepreg material 22 may be further wound on the tip side of the core material 20. At this time, prepreg materials having different orientation directions of reinforcing fibers are used. After the necessary prepreg material 21 is wound around the core material 20, a forming tape or the like is further wound around the outermost layer for protection and formation, and these are fired in a furnace to solidify and integrate the prepreg material. And the core material 20 is pulled out to the large diameter side, and a tubular body is obtained. The tubular body obtained in this way can be used as a base rod 1 having a straight female portion whose diameter does not change on the inner peripheral surface on the tip side. In particular, if such a core material 20 is used, the end of the straight female portion 11 on the heel side becomes a curved surface, and when the middle heel 2 is inserted into and removed from the inside of the heel 1 to the tip side, the heel of the straight female portion It is also possible to suppress the hook 2 from being caught by the end on the original side.
(About Lieutenant 2)
As shown in FIGS. 2 and 3, the intermediate collar 2 is also a tubular body tapered as a whole. A fitting male portion Y is formed on the outer periphery of the base side end portion. The fitting male part Y is a part that is one step thicker than the other parts. Such a fitting male part Y is, for example, formed in a part on the base side when the prepreg material is wound around the core material and fired to produce the upper part 2 as described in the above-mentioned main part 1. The auxiliary prepreg for forming the fitting male part Y can be wound and formed. As such an auxiliary prepreg, a prepreg material obtained by impregnating boron fibers or metal fibers with a synthetic resin may be used. The wear resistance of the fitting male part Y improves by using the thing using such a fiber.

  Specifically, the fitting male part Y is formed adjacent to the tapered male part 13 that can be fitted to the tapered female part 10 formed on the tip side, and can be fitted to the straight female part 11. Straight portion 14. The taper rate of the taper male part 13 is adjusted to match that of the taper female part 10 described above. The straight portion 14 is adjusted so that the outer diameter thereof matches the inner diameter of the straight female portion 11, and the diameter does not change in the axial length direction. In the straight portion 14 of the fitting male portion Y, a split is formed in the axial direction from the heel-side end portion of the intermediate collar 2 (that is, the heel-side end portion of the straight portion 14). Only one split may be formed. However, a plurality of splits may be formed at intervals in the circumferential direction. A lubricant may be further applied to the outer peripheral surface of the straight portion 14. Examples of the lubricant include performing Teflon (registered trademark) processing and the like.

  Here, the fitting female portion X and the fitting male portion Y of the main rod 1 and the middle rod 2 have been described, but the same structure is also adopted at the connecting portion of the middle rod 2 and the tip rod 3. .

  In the fishing rod as described above, the middle rod 2 and the tip rod 3 housed inside the base rod 1 are sequentially pulled out toward the tip side, and the fitting female portion X and the fitting male portion Y of each rod are fitted. It will be used as a single fishing rod. At the time of connecting the respective housings as described above, the connecting portions are as follows. For example, when the middle rod 2 is pulled out toward the tip of the main rod 1, first, the straight female portion 11 of the fitting female portion X and the straight portion 14 of the fitting male portion Y contact each other (see FIG. 3). Both are regions in which the inner diameter does not change in the axial direction, and a relatively low-cost fitting force is continuously produced as the middle collar 2 is pulled out. In addition, the straight portion 14 is formed with a split to improve the elasticity or dimensional absorption in the radial direction, and the straight portion 14 smoothly fits or contacts the straight female portion 11 and slides. Further, if a lubricant is applied to the straight portion 14, further excessive wear of both is prevented. Thereafter, the taper female portion 10 of the fitting female portion X of the main shaft 1 and the taper male portion 13 of the fitting male portion Y are in contact with each other, and both produce a sufficient fitting force in a state in which both the tapers coincide with each other. (See FIG. 2).

  On the other hand, when the intermediate rod 2 is housed in the main rod 1 and the fitting between the two is released, the tapered female portion 10 of the fitting female portion X and the fitting male portion Y of the main rod 1 are firstly reversed. Contact with the tapered male portion 13 is released. Also in this case, the straight portion 14 of the fitting male portion Y is fitted or abutted on the straight female portion 11 of the fitting female portion X, and both the housings slide smoothly, so that a relatively inexpensive fitting force is obtained. Directing.

Further, the same operation is performed on the middle rod 2 and the tip rod 3.
By fitting the housings through such a process, the user can foresee in advance that the housings are completely fitted and their positions are fixed during operation, and this operation can be performed smoothly. It will be. Moreover, when both housings are completely fitted, the straight portion 14 and the straight female portion 13 also produce a constant fitting force, and the stability when the housings are fitted is also improved. Similarly, when releasing the fit, the user can foresee the release of the fit, and this operation can be performed smoothly.

[Second Embodiment]
The modification of the fitting male part Y of a middle collar is shown below.

  As shown in FIG. 5, the intermediate collar 22 is also a tubular body tapered as a whole. A fitting male portion Y is formed on the outer periphery of the base side end portion. The fitting male part Y is a part that is one step thicker than the other parts. The fitting male portion Y also includes a tapered male portion 23 formed on the tip side and a straight portion 24 formed adjacent to the tapered male portion 23.

  The straight portion 24 has a plurality of small circular coatings randomly applied on its peripheral surface. For example, such painting is performed from a paint such as an epoxy resin or a urethane resin. The method such as dipping or sticking with a seal can be arbitrarily selected. The height of the small circular part to be painted is about 0.01 to 0.15 mm. For example, if a metal-based paint is used, the design will be excellent.

  When such a straight portion 24 is used, the contact area between the straight portion 24 and the straight female portion of the main rod 1 becomes small, and both the casings slide smoothly, and a relatively inexpensive fitting force can be produced. Further, if a rubber-based paint is used, the dimensional absorbability is further improved.

[Third Embodiment]
As shown in FIG. 6 and FIG. 7, the curved surface portions 34a and the flat surface portions 34b are alternately arranged in the circumferential direction on the circumferential surface of the straight portion 34 of the middle fitting male portion, and The directional cross section may be processed into a non-circular shape. Such a planar portion can be formed by forming the straight male portion 34 by the above-described manufacturing method and then partially scraping the peripheral surface into a planar shape.

  Even if such a straight male part 34 is used, the contact area between the straight male part 34 of the fitting male part of the middle rod 2 and the straight female part of the main rod 1 is reduced, and both the casings slide smoothly. In addition, a relatively inexpensive fitting force can be produced.

[Fourth Embodiment]
A modification of the marshal of the first embodiment is shown in FIG.

  As shown in detail in FIG. 8, the base rod 51 is a tubular body that is tapered so that the diameter of the tip side is reduced as a whole. The inner peripheral surface on the tip side is a fitting female portion X for connection with the former upper collar 52. Specifically, the fitting female portion X has a tapered female portion 60 that increases in diameter from the edge of the tip side of the heel 51 toward the heel side, and a taper that is continuously formed on the heel side of the tapered female portion 60. It consists of a surface portion 61 and a straight surface portion (straight female portion) 62. The tapered surface portions 61 and the straight surface portions (straight female portions) 62 are formed alternately in the circumferential direction in the same axial region (see FIG. 9).

  As shown in FIG. 9, the tapered surface portion 61 extends in the axial length direction in three regions that are equally spaced in the circumferential direction. The tapered surface portion 61 is basically a tapered surface that is continuous with the tapered female portion 60 of the fitting female portion X. Further, the straight surface portion (straight female portion) 62 is three portions formed in a circumferential direction between the tapered surface portions 61. The straight surface portion (straight female portion) 62 is a portion whose inner diameter does not change in the axial length direction. A method for manufacturing the straight surface portion (straight female portion) 62 will be described later.

  In addition, in this marshall 51, the taper surface part 61 and the straight surface part 62 are formed in three places, but the number can be set arbitrarily.

Next, an example of a method for manufacturing the marshal 51 will be described.
As shown in FIG. 10, a core member 65 having a predetermined tapered taper is prepared. On the tip side of the core material 265, a part of the outer peripheral surface is notched to form a surface whose diameter does not change in the axial length direction. A necessary number of the surfaces whose diameters do not change are formed at intervals in the circumferential direction. A release material or the like is applied to the peripheral surface of the core member 65 as necessary, and the prepreg material 21 is wound. The prepreg material 21 is the same type as the above-described embodiment.

  After the necessary prepreg material 21 is wound around the core material 65, a forming tape or the like is further wound around the outermost layer for protection and formation, and these are fired in a furnace to solidify and integrate the prepreg material. And the core material 65 is pulled out to the large diameter side, and a tubular body is obtained. At this time, a part of the peripheral surface on the tip side of the core material 65 is a portion where the diameter does not change, but the core material 65 can be pulled out to the large diameter side. In this way, a tubular body having a portion whose diameter does not change in a portion of the inner peripheral surface on the tip side and having a taper taper at the other portion is obtained.

  By using such a main rod 51, the contact area between the straight female portion 62 and the straight portion of the middle rod is reduced, and compared with the case where the straight female portion is formed in the entire circumferential direction, mutual contact or The fitting becomes loose, wear and the like hardly occur, and sticking hardly occurs.

[Fifth Embodiment]
FIG. 11 shows another modified example of the middle collar. This intermediate collar 72 is also a tubular body with a tapered taper as a whole. A fitting male portion Y is formed on the outer periphery of the base side end portion. The fitting male part Y is a part that is one step thicker than the other parts. Similarly to the above-described embodiment of the fitting male portion Y, an auxiliary prepreg for forming the fitting male portion Y can be wound around the base side portion. In particular, a special auxiliary prepreg may be used in an area of about 10 mm at the base end of the fitting male part Y. As this special auxiliary prepreg, a material in which the reinforcing fibers are oriented only in the axial direction in which the reinforcing fibers are not oriented in the circumferential direction is used.

The marshal is the same marshal 1 as in the first embodiment.
More specifically, the fitting male portion Y of the intermediate collar 72 is formed adjacent to the tapered male portion 73 and the tapered male portion 73 that can be fitted to the tapered female portion 10 formed on the tip side of the base rod 1. And a straight portion 74. The taper ratio of the taper male part 73 is adjusted so as to match that of the taper female part 10 of the above-mentioned main shaft 1. The straight portion 74 is a portion whose outer diameter is adjusted to be smaller than the inner diameter of the straight female portion 11 and the diameter does not change in the axial length direction. In the straight portion 74 of the fitting male portion Y, a concave groove is formed in the circumferential direction over the entire circumference thereof. A rubber ring 75 is accommodated in the concave groove. Although the rubber ring 75 is used here, a ring made of a hard member such as ceramics may be used instead. The outer diameters of these rubber rings 75 and the like are adjusted according to the inner diameter of the straight female portion 11 of the main shaft 1.

  When such a middle collar 72 is used, when the middle collar 72 is pulled out toward the tip side of the base rod 1, first, the straight female portion 11 and the male portion Y of the fitting female portion X of the base rod 1 are firstly connected. The rubber ring 75 contacts the peripheral surface of the straight portion 74. As a result, a relatively inexpensive fitting force is continuously produced as the middle collar 72 is pulled out. Then, the straight portion 74 or the rubber ring 75 smoothly slides while being fitted to or in contact with the straight female portion 11. If a ceramic ring is used, excessive wear of both is also prevented. Thereafter, the taper female part 10 of the fitting female part X of the main shaft 1 and the taper male part 73 of the fitting male part Y are in contact with each other, and both produce a sufficient fitting force in a state in which both the tapers coincide. .

  On the other hand, when the intermediate rod 2 is housed in the main rod 1 and the fitting between the two is released, the tapered female portion 10 of the fitting female portion X and the fitting male portion Y of the main rod 1 are firstly reversed. The contact with the taper male part 73 is released. Also at this time, the rubber ring 75 on the peripheral surface of the straight portion 74 of the fitting male portion Y is fitted or abutted on the straight female portion 11 of the fitting female portion X, and both the casings slide smoothly. Produces a relatively inexpensive fitting force.

[Sixth Embodiment]
Another fishing rod 81 and middle rod 82 relating to the present invention will be described with reference to FIGS. This fishing rod is also composed of a main rod 81, a middle rod 82 connected in a swinging manner to the tip of the main rod 81, and the remaining rods, as in the above embodiments.

  The base rod 81 is a tubular body that is tapered so that the diameter of the tip side is reduced as a whole. However, in a certain region in the axial length direction from the end on the tip side, a straight portion is formed in which neither the outer diameter nor the inner diameter changes in the axial length direction. A part of the inner peripheral surface of the straight portion and the taper portion on the base side thereof is a fitting female portion X for connection with the intermediate collar 82. That is, the fitting female portion X includes a straight female portion 90 whose diameter does not change from the edge on the tip side of the heel 81 to the heel side, and the heel side on the heel side of the straight female portion 90 continuously to the heel side. It consists of a tapered female portion 91 that increases in diameter. In the straight female portion 90 of the fitting female portion X, a split is formed in the axial length direction from the tip side end portion of the base rod 81 (that is, the tip side end portion of the straight female portion 90). Only one split may be formed. However, a plurality of splits may be formed at intervals in the circumferential direction.

  The intermediate collar 82 is also a tubular body tapered as a whole. A fitting male portion Y is formed on the outer periphery of the base side end portion. The fitting male portion Y includes a portion that is one step thicker than the other portions. Such a fitting male part Y is the same as that of the said embodiment. That is, the fitting male portion Y is composed of a tip side portion 92 and a heel side portion 93. Specifically, the tip side portion 92 has a larger outer diameter on the tip side formed on the tip side where the outer diameter does not change in the axial length direction, or on the portion where the outer diameter does not change almost in the axial length direction, or on the heel side. It is a part to do. The heel side portion 93 is a portion formed by increasing the diameter by one step on the heel side of the tip side portion 92, and is a portion whose outer diameter increases toward the heel side. The diameter of the heel side portion 93 is adjusted so that it can be fitted to the tapered female portion 91 described above.

  On the peripheral surface of the tip side portion of the fitting male part Y of the intermediate collar 82, a concave groove is formed in the circumferential direction over the entire circumference. A rubber ring 94 is accommodated in the concave groove. The outer diameter of the rubber ring 94 is adjusted in accordance with the inner diameter of the straight female portion 90 of the fitting female portion X of the base rod 81 described above.

  The fishing rod as described above is such that the middle rod 82 and the like housed inside the base rod 81 are sequentially pulled out toward the tip, and the fitting female portion X and the fitting male portion Y of each rod are fitted, It will be used as a single fishing rod. At the time of connecting the respective housings as described above, the connecting portions are as follows. For example, when the middle rod 82 is pulled out toward the tip of the base rod 81, first, the rubber ring 94 contacts the straight female portion 90 of the fitting female portion X of the base rod 81 (see FIG. 13). The straight female portion 90 is a region in which the inner diameter does not change in the axial length direction, and a relatively inexpensive fitting force is continuously produced as the middle collar 82 is pulled out. Further, the straight female portion 90 is formed with a split to improve radial elasticity or dimensional absorption, and the rubber ring 94 is smoothly fitted into or in contact with the straight female portion 90 and slides. Thereafter, the taper female portion 91 of the fitting female portion X of the base rod 81 and the heel side portion 93 of the fitting male portion Y come into contact with each other, and both produce a sufficient fitting force. (See FIG. 12).

  On the other hand, when the intermediate collar 82 is accommodated in the base rod 81 and the fitting of both is released, the taper female portion 91 of the fitting female portion X and the fitting male portion Y of the base rod 81 are first reversed. The contact with the heel side portion 93 is released. Also in this case, the rubber ring 94 of the fitting male part Y is fitted or abutted on the straight female part 90 of the fitting female part X, so that both housings slide smoothly, and a relatively inexpensive fitting force. Directing.

[Seventh Embodiment]
Further, another marshal rod 101 and middle rod 102 according to the present invention will be described with reference to FIGS. 14 and 15.

  The main rod 101 is a tubular body that is tapered so that the diameter of the tip side is reduced as a whole. The inner peripheral surface on the tip side is a fitting female portion X for connection with the intermediate collar 102 as in the first embodiment. Specifically, the fitting female portion X is continuously formed on the heel side of the taper female portion 110 and the taper female portion 110 that increases in diameter from the edge on the tip side of the heel 101 toward the heel side. The straight female portion 111 is formed. The straight female portion 111 is a portion whose diameter does not change in the axial length direction (see the description of the first embodiment for the method of manufacturing the main shaft 101).

  As shown in FIG. 15, the intermediate collar 102 is also a tubular body having a tapered taper as a whole. A fitting male portion Y is formed on the outer periphery of the base side end portion. The fitting male part Y is a part whose diameter is increased by one step compared to the other parts (see also the description of the first embodiment regarding the manufacturing method of such a fitting male part Y).

  More specifically, the fitting male part Y is formed so as to be fitted to the tapered female part 110 formed on the tip side, and to the straight female part 111 formed adjacent to the tapered male part 113. Straight portion 114. The taper rate of the tapered male part 113 is adjusted to match that of the tapered female part 110 described above. The straight portion 114 is adjusted so that its outer diameter is slightly smaller than the inner diameter of the straight female portion 111, and the diameter does not change in the axial length direction.

  The flange-side end portion of the straight portion 114 of the fitting male portion Y (that is, the flange-side end portion of the center rod 102) is split in the axial direction from the flange-side end edge in the circumferential direction. It is formed at a plurality of locations. This split is formed by cutting the rim side edge of the intermediate collar 102 into a corrugated shape. More specifically, about 2 to 4 cracks that are recessed into the tip side are formed at the heel side end edge of the center rod 102 while being spaced apart in the circumferential direction. The individual splits are formed side by side in the circumferential direction while gently curving the waveform. The depth in the axial length direction of the groove to be recessed is about 5 to 10 mm. Such a recess can be formed by manufacturing the intermediate collar 102 by the method described in the above embodiment and then shaving the peripheral surface of the collar side.

  In addition, an elastic rubber paint 115 is dipped between the corrugated portions formed as described above on the peripheral surface of the straight portion 114 of the fitting male portion Y to form an elliptical elastic body 115. The height of the elastic body 115 thus dipped is about 0.01 to 0.15 mm. The maximum outer diameter of the straight portion 114 including the elastic body 115 is set to be a little larger than the inner diameter of the straight female portion 111 as in the above-described inner diameter of the straight female portion 111. The elastic body 115 can enter and exit in the radial direction due to the elasticity of the material, and the elastic body 115 abuts or fits on the straight female portion 111.

  In the fishing rod as described above, the middle rod 102 and other rods housed inside the base rod 101 are sequentially pulled out toward the tip, and the fitting female portion X and the fitting male portion Y of each rod are fitted. Let it be used as a single fishing rod. At the time of connecting the respective housings as described above, the connecting portions are as follows. For example, when the middle hook 102 is pulled out to the tip side of the base rod 101, first, it is dipped on the circumferential surface of the straight female portion 111 of the fitting female portion X of the base rod 101 and the straight portion 114 of the fitting male portion Y. The elastic body 115 comes into contact. The elastic body 115 is applied to the peripheral surface between the split portions of the straight portion 114, and the elasticity or dimensional absorbability in the radial direction is improved by the elasticity and splitting of the material itself. The female part 111 slides in contact with or in contact with the female part 111. Then, the taper female part 110 of the fitting female part X of the main shaft 101 and the taper male part 113 of the fitting male part Y come into contact with each other, and the two produce a sufficient fitting force in a state where the two tapers coincide with each other. .

  On the other hand, when the intermediate collar 102 is housed in the main rod 101 and the fitting between both is released, the tapered female portion 110 of the fitting female portion X and the fitting male portion Y of the main rod 101 are first reversed. The contact with the taper male part 113 is released. Even in this case, the elastic body 115 of the fitting male part Y is fitted or abutted on the straight female part 111 of the fitting female part X, and both the casings slide smoothly, so that a relatively inexpensive fitting force is obtained. Directing.

[Eighth Embodiment]
FIG. 16 shows still another modified example of the fitting male portion Y of the middle collar.

  As shown in FIG. 16, the intermediate collar 122 is also a tubular body having a tapered taper as a whole. A fitting male portion Y is formed on the outer periphery of the base side end portion. The fitting male part Y is a part that is one step thicker than the other parts. And this fitting male part Y also consists of the taper male part 123 formed in the tip side, and the straight part 124 formed adjacent to the taper male part 123 (About the manufacturing method, it is 1st Embodiment. See).

  The straight portion 124 is formed with an elastic body 125 by applying a plurality of rubber-based coatings on the peripheral surface thereof. The elastic bodies 125 are first formed in the vicinity of the rear end of the straight portion 124 in the circumferential direction with a gap in the circumferential direction, and constitute the first elastic body group F. About 4 to 6 elastic bodies 125 forming the first elastic body group F are arranged at equal intervals in the circumferential direction. Further, another elastic body 125 is formed side by side in the circumferential direction on the circumferential surface of the straight portion 124 displaced from the first elastic group F to the tip side in the axial direction, and the second elastic group S Is configured. About 4 to 6 elastic bodies 125 constituting the second elastic body group S are also arranged at equal intervals in the circumferential direction. However, as shown in FIG. 16, the elastic body 125 constituting the first elastic body group F and the elastic body 125 constituting the second elastic body group S are displaced in the circumferential direction. That is, the elastic body 125 constituting the second elastic body group S is disposed at a position between the elastic bodies 125 constituting the first elastic body group F in the circumferential direction.

  For example, the coating for forming such an elastic body 125 is performed by a paint such as an epoxy resin or a urethane resin. The method such as dipping or sticking with a seal can be arbitrarily selected. The height of the small circular part to be painted is about 0.01 to 0.15 mm. If a metal-based paint is used, the design will be excellent. In addition, as shown in FIG. 16, it is preferable that each elastic body 125 has a substantially triangular shape that is narrower toward the tip side and wider toward the heel side.

  When the elastic body 125 is formed on the straight portion 124 in this way, and the elastic body 125 is used, the contact area between the straight female portion of the base rod and the elastic body 125 is reduced, and both the housings slide smoothly. A relatively inexpensive fitting force can be produced. Further, if a rubber-based paint is used, the dimensional absorbability is further improved. In addition, as shown in FIG. 16, if the elastic body 125 is disposed on the circumferential surface of the straight portion 124, it is difficult to generate an undue squeak noise or the like between the elastic body 125 and the main rod.
