Description

  The present invention relates to a fishing rod formed by connecting a plurality of rods. In particular, the present invention relates to a fishing rod that connects rods in a swinging manner.

  Many recent fishing rods are provided with a plurality of rods, which are cylindrical bodies with a tapered taper, and these rods are connected to form a single fishing rod. One of such methods for connecting the enclosures is called an “emergence format”. In a fishing rod in which the rods are connected to each other in this swinging form, the small-diameter rods located on the tip side are sequentially housed in the large-diameter rods located on the rod side, and the small-diameter rod is located on the tip side. When the casing is pulled out, the outer periphery of the base end of the small diameter casing and the inner periphery of the tip end of the large diameter casing are fitted.

In such a portion for connecting the casings, various techniques have been proposed in order to prevent wear between the casings and smooth the bending rigidity. For example, a technique for laminating a prepreg using a special polyester fiber as a supplementary technique or a technique for laminating reinforced prepregs with respect to the axial direction (for example, see Patent Document 1). Technology to do.

  By the way, one of the problems that arises when fishing for a long time is to repeatedly swing the fishing rod, throw it at the point where the device is aimed, and swing up the fishing rod to raise the fish. Is very tired.

  As described above, so far, only the problems such as the reduction of the fitting force due to wear and the adjustment of the bending of the casing have been focused on the fitting portion for connecting the casings. It was. The improvement of the connection part of the frames considering the above-mentioned problem of hand fatigue has not been made so far.

  The present invention provides a fishing rod in which the hand operating the fishing rod is less tired even when fishing is performed for a long time.

  One of the causes of tiredness of the hand operating the fishing rod when fishing for a long time is that the vibration generated in the fishing rod bounces off from the tip of the fishing rod when the fishing rod is shaken, and acts on the hand operating the fishing rod. The present inventors have found that there is a point to do. The present invention is based on such knowledge.

  The fishing rod of the present invention is a fishing rod formed by connecting a plurality of rods in a swing-out manner, and includes a first rod having a fitting layer made of an elastic material provided on an inner peripheral surface on the tip side, and a first rod It is a casing connected to the tip side of the casing, and is provided with a second casing having a fitting male part that is formed on the outer peripheral surface of the base side and can be fitted to the fitting layer.

  In this fishing rod, the second rod is connected to the tip of the first rod in a swinging manner to form one fishing rod. When the second casing is pulled out toward the tip of the first casing in a swinging manner, the fitting male part of the second casing is fitted into the fitting layer of the first casing, and both are connected and fixed. Even if the fishing rod is shaken to generate vibration and the vibration bounces back from the tip of the fishing rod to the hand side, the fitting between the second rod and the first rod is through the fitting layer, The vibration that bounces back to the first housing is weakened by the elastic material of the fitting layer.

  For example, the area of the fitting layer of the first casing has a smaller inner diameter than the other parts, and the first casing has an inner circumferential surface spaced from the fitting layer to the collar side. It is good also as what has a fitting female part. In this case, when the second casing is pulled out and connected to the tip side of the first casing, the fitting male part of the second casing is fitted to the fitting layer, and further, the base end of the fitting male part The edge is fitted to the fitting female part.

  That is, the second housing is in contact with the first housing at two locations in the axial length direction of the base-side edge and the fitting layer, and the vibration of the second housing is the base-side edge. The fitting layer made of an elastic material effectively absorbs this. In addition, it is preferable to form a fitting layer over the perimeter of the circumferential direction in the tip side edge part of a 1st housing. By forming the fitting layer over the entire circumference in the circumferential direction, when the second housing is pulled out to the tip side of the first housing, the fitting layer and the second housing are placed on the tip side of the first housing. A lid is formed so that water or the like can be prevented from entering the first housing from the outside.

  According to the present invention, in the connecting portion between the rods, the vibration from the rod arranged on the tip side to the hand side is reduced, and even if fishing is performed for a long time, the hand operating the fishing rod is hard to get tired.

[First Embodiment]
A fishing rod adopting one embodiment of the present invention has, for example, a former rod 1, and a former rod 2, a middle rod and a tip rod (not shown) connected in sequence to the head side of the former rod 1 (See FIG. 1). Each casing is a tubular body with a tapered taper made of a prepreg material obtained by impregnating carbon fiber or glass fiber with a synthetic resin. However, the number of housings is not limited to this, and can be set arbitrarily.

  A reel seat on which a reel can be detachably mounted, a grip for a fisherman to hold the main rod 1 and perform a fishing operation, and the like are provided on the peripheral surface of the front side of the main rod 1. Further, a fishing line guide for sequentially guiding the fishing line from the reel to the tip side is disposed on the circumferential surface. A plurality of fishing line guides for guiding the fishing line from the reel to the tip side are also arranged on the peripheral surface of the former upper rod 2 at intervals in the axial length direction.

With reference to FIG. 1, the connecting portion between the former fence 1 and the former upper fence 2 will be described.
As described above, the main rod 1 is a tubular body tapered as a whole, and the fitting layer 10 made of an elastic material (for example, milactolan / EVA resin) is provided at the end of the tip side. . The fitting layer 10 is formed from, for example, a cylindrical member having a portion whose outer diameter is enlarged like a bowl at the tip end portion. The outer diameter of this hook-shaped part is matched with the outer diameter of the tip side of the heel 1, and the part other than the hook-like part is fitted on the tip side of the heel 1. The inner diameter of the cylindrical member forming the fitting layer 10 is adjusted according to the outer diameter of the fitting male part of the former upper collar 2 described later. The fitting layer 10 forms a cylindrical member separately from the main bar 1 and fixes it to the main bar 1 with an adhesive or the like.

  The former upper collar 2 is also a tubular body that is tapered as a whole as described above. The outer diameter of the base side is larger by one step than the other part, and this thickened part is the fitting male part 2a. When such a fitting male part 2a manufactures the upper collar 2, the auxiliary prepreg is separately laminated and fired in a predetermined region on the collar side, and the outer peripheral surface is ground and the diameter is adjusted after firing. It is formed by techniques.

  More specifically, the fitting male portion 2a has a first taper portion that gradually increases in diameter toward the heel side on the tip side, and a diameter that hardly changes in the axial length direction continuous to the heel side of the first taper portion. It is divided into a straight portion and a second taper portion that continues to the base side of the straight portion and gradually increases in diameter toward the base side. The outer diameter of the straight portion is adjusted according to the inner diameter of the fitting layer 10 described above. The outer diameter of the heel side end portion of the second taper portion (that is, the heel side end portion of the former upper heel 2) is the inner diameter of the heel side of the heel 1 (specifically, slightly in the axial length direction from the fitting layer 10). It is adjusted according to the inner diameter of the part away from the collar side (see P in FIG. 1).

  In addition, here, in the connection part of the main frame 1 and the former upper frame 2, the connection part of the frames is described, but the same structure is adopted also in the connection part of the other frames. Also good.

  In the fishing rod constructed in this way, the upper rod 2 is pulled out to the tip side of the main rod 1, and the remaining rods are sequentially pulled out to the tip side, and the rods are connected to each other. Become. For example, when the upper arm 2 is pulled out to the tip side of the former foot 1 in a swinging manner, the fitting male part 2a of the upper arm 2 is fitted to the inner peripheral surface of the front end of the former foot 1 as shown in FIG. The two are connected and fixed. Specifically, the straight portion of the fitting male portion 2a is on the fitting layer 10 of the base rod 1, and the hook side edge of the fitting male portion 2a is the inner peripheral surface on the tip side of the base rod 1 (specifically, fitting) The portion 10 is slightly fitted in the axial length direction from the layer 10 and is a fitting female portion in which a part of the fitting male portion 2a is fitted in a circumferential shape.

  The fishing rod swung during the fishing operation performed by holding the main rod 1 is vibrated from the main rod 1 side. And the vibration bounces back to the hand side from the tip of the fishing rod. Such vibrations that bounce back to the hand side are weakened by the elastic material of the fitting layer 10, and vibrations that bounce back to the fisherman's hand holding the main rod 1 are weakened. In particular, the upper collar 2 is connected to the collar 1 at an edge of the collar side and the fitting layer 10 at two locations apart in the axial length direction. Therefore, the vibration of the upper collar 2 occurs around the edge on the collar side, and the fitting layer 10 made of an elastic material effectively absorbs this. In addition, the fitting layer 10 of the main rod 1 is formed of a cylindrical member having a hook-shaped portion, and when the upper upper rod 2 is fitted, water enters the main rod 1 from the outside. It also prevents intrusion. In addition, this hook-shaped portion prevents damage to the edge on the tip side of the base rod 1.

[Second Embodiment]
A modification of the above embodiment is shown in FIG. Also in this fishing rod, the former upper rod 12 is connected to the tip side of the former rod 11 in a swinging form.

  The main rod 11 is also a tubular body tapered as a whole. A fitting layer 20 made of an elastic material (for example, milactolan / EVA resin or the like) is provided at the tip end portion. The fitting layer 20 is formed on the inner surface over an area of about 5 mm in the axial length direction from the tip side end portion of the base rod 11. For example, the marshal 11 is manufactured by a technique as shown in FIG.

  First, a core material 50 having a predetermined taper is prepared, and a release material or the like is applied to the peripheral surface as necessary. The elastic material sheet S <b> 1 for forming the fitting layer 20 is wound around the tip side region of the core material 50. A predetermined prepreg material S2 is further wound around the peripheral surfaces of the elastic material sheet S1 and the core material 50. The prepreg material S <b> 2 may be a sheet-shaped material wound around the core material 50, or a tape-shaped material may be spirally wound. Alternatively, a sheet form or a tape form may be used in combination. These prepreg materials include carbon fibers and the like that are aligned in a certain direction, and the fiber direction is also selected in any combination with the axial length direction, the circumferential direction, and the spiral direction of the core material 50. Thereafter, after winding a protective tape or the like around the outermost periphery, these materials are fired in a furnace. The core 50 is drawn out, both ends are trimmed, the outer peripheral surface is polished, the diameter is adjusted, and the base iron 11 is manufactured. Thereafter, the inner peripheral surface on the tip side of the base rod 11 is further polished to adjust the diameter. In this way, the inner surface of the fitting layer 20 is flush with the inner surface of the remaining base 11.

  The original upper collar 12 is also a tubular body tapered as a whole as described above. The base side has an outer diameter that is one step thicker than the other parts, and this thickened part is the fitting male part 12a. More specifically, the fitting male portion 12a has a first taper portion that gradually increases in diameter toward the heel side on the tip side, and a first taper portion that is continuous to the heel side of the first taper portion, and more gently on the heel side. It is divided into a second tapered portion that gradually increases in diameter toward the side. The outer diameter of the second taper portion is adjusted in accordance with the inner diameter (including the fitting layer 20) on the tip side of the above-mentioned base rod 11.

  In the fishing rod constructed in this way, the upper rod 12 is pulled out to the tip side of the genius rod 11, and the remaining rods are also pulled out to the tip side in order to connect the rods to each other. Become. For example, when the former upper collar 12 is pulled out to the tip side of the former basket 11 in a swinging manner, the fitting male part 12a of the former upper collar 12 is fitted to the inner peripheral surface of the former edge 11 on the tip side as shown in FIG. The two are connected and fixed. In detail, the 2nd taper part of the fitting male part 2a is fitted to the fitting layer 20 of the main shaft 1 and the other inner peripheral surface.

  During the fishing operation performed by holding the main rod 11, vibration is generated from the side of the main rod 11 in the swinged fishing rod. And the vibration bounces back to the hand side from the tip of the fishing rod. Such vibration that bounces back to the hand side is weakened by the elastic material of the fitting layer 20, and vibration that bounces back to the angler's hand that holds the barb 11 is weakened.

  In this embodiment, not only the fitting layer 20 but also the inner peripheral surface of the main shaft 11 itself is fitted with the fitting male portion 12a. Instead, the axial length of the fitting layer 20 may be set to be long so that the fitting male portion 12a is received only by the inner peripheral surface of the fitting layer 20.

[Third Embodiment]
Yet another embodiment is shown in FIG. Even in this fishing rod, the former upper rod 22 is connected to the tip side of the former rod 21 in a swinging manner.

  The main rod 21 is also a tubular body that is tapered as a whole. A fitting layer 30 made of an elastic material (for example, milactolan / EVA resin or the like) is provided at the tip end portion. The fitting layer 30 is formed on the inner surface over an area of about 5 mm in the axial length direction from the tip side end portion of the base rod 21. For example, the marshal 21 is manufactured by a method as shown in FIG.

  First, a core material 60 having a predetermined taper is prepared, and a release material or the like is applied to the peripheral surface as necessary. The core material 60 has a one-step diameter reduction at a part on the tip side. The elastic material sheet S <b> 1 for forming the fitting layer 30 is wound around a region where the diameter of the core material 60 is reduced by one step. Then, a predetermined prepreg material S <b> 2 is further wound around the peripheral surfaces of the elastic material sheet S <b> 1 and the core material 60. The remaining steps are the same as those in the second embodiment, and a description thereof is omitted. By pulling out the core material 60 to the thicker diameter side, it is possible to obtain the main rod 21 which is a tubular body whose fitting layer 30 portion on the tip side is one step smaller in diameter than the other portions.

  The original upper collar 22 is also a tubular body that is tapered as a whole as described above. The base side has an outer diameter that is one step thicker than the other parts, and this thickened part is the fitting male part 22a. More specifically, the fitting male portion 22a has a first taper portion that gradually increases in diameter toward the heel side on the tip side and a first taper portion that is continuous with the heel side of the first taper portion, and more gently on the heel side. The taper is divided into a second taper portion that gradually increases in diameter toward the side and a third taper portion that increases in diameter toward the base side more rapidly than the second taper portion that continues from the base side of the second taper portion. The outer diameter of the second taper portion is adjusted in accordance with the inner diameter of the fitting layer 30 of the above-described base 21. Further, the outer diameter of the base end of the third taper portion (that is, the base end of the base upper collar 22) is the inner diameter of the base end of the base collar 11 (specifically, the axial direction from the fitting layer 30) The inner diameter of the portion slightly distant from the base side is adjusted (see P in FIG. 4).

  The fishing rod thus configured can also be used in the same manner as in the first embodiment described above.
