Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a connecting structure for fishing rod bodies that are used by connecting a plurality of rod bodies.
[0002]
[Prior art]
Conventional fishing rods that are used by connecting a plurality of rods are roughly classified into a swing type and a joint type.
The connecting structure of the housings according to the swing-out form is connected to the tubular first housing and the tip side of the first housing so as to be freely inserted into the first housing. In use, the second housing is protruded from the first housing to the tip side, and is fitted between the base side outer peripheral surface of the second housing and the tip side inner peripheral surface of the first housing. It is assumed that At the time of storage, the second housing is inserted into the first housing to make it compact.
[0003]
Moreover, the connection structure of the frame which concerns on a parallel connection form has the 1st case which has a fitting female part in the tip side tip, and the 2nd case which has a fitting male part in the base side end part. Have. The first casing and the second casing are cylindrical members formed with a taper so that the diameter is smaller toward the tip side. At the time of use, the fitting male part of the second casing is inserted and fitted into the fitting female part of the first casing, and used as one casing.
[0004]
[Problems to be solved by the invention]
In both the swing-out type and the joint type, precise work is required for designing the fitting portion for fitting the casings together. If the diameters of the fitting portions of the respective housings are not made to coincide with each other very precisely, the transmission of force at the connecting portions of the housings and the degree of bending as a single housing will be greatly affected. This is because the simultaneous desorption work cannot be performed smoothly. However, such precise work of matching the diameters of the rods requires time, labor, and a certain technique, leading to high costs for the entire fishing rod.
[0005]
In addition, there is a conventional fishing rod that connects two or more rods so that fishing can be performed while adjusting the overall length of the rod. For example, the state of both the state in which the boss is inserted into the heel (inserted state) and the state in which the boss is pulled out (stretched state) in relation to the heel In the above, the former upper collar and the former collar can be freely fitted. In such a fishing rod, both the heel-side outer peripheral surface and the tip-side outer peripheral surface of the former upper rod are fitted with the inner-end surface of the tip-side end portion of the former rod.
[0006]
As described above, it is more troublesome to set the diameter so that both the tip side outer peripheral surface and the heel side outer peripheral surface of the genital upper heel are precisely fitted to the heel. Furthermore, since the outer surface of the upper heel is polished or coated with a resin to finely adjust the outer diameter of the heel of the original heel, the appearance may be deteriorated.
The subject of this invention is providing the connection structure of the housing which can fit a housing precisely with a simple structure.
[0009]
[Means for Solving the Problems]
The connecting structure of the casings according to the first aspect of the present invention is a connecting structure of the casings connected in a swing-out manner, and is formed on the inner peripheral surface of the cylindrical main body portion and the tip side end portion of the main body portion and is softer than the main body portion. A first casing having a buffer layer and a tapered member that tapers toward the tip side, and is formed to have a larger diameter from the center in the length direction to the tip side than the other portions. An outer diameter of one outer peripheral surface is formed to be substantially the same as an outer diameter of the second outer peripheral surface of the end portion on the heel side, and includes a second casing inserted into the first casing, The second housing can be fitted to the buffer layer of the first housing on both the first outer peripheral surface and the second outer peripheral surface.
When the fishing rod having this fitting structure is used as a single fishing rod, the second rod is pulled out to the tip side of the first rod, and the rod-side end outer peripheral surface of the second rod is the first rod. Used by being fixed to the body buffer layer. At this time, the buffer layer softer than the main body portion of the first casing is appropriately deformed so as to be fitted to the base side of the second casing. For this reason, the base side end outer diameter of the second housing and the buffer layer inner diameter of the first housing do not require precise matching, and a stable connected state can be produced relatively easily.
In this structure, for example, in a fishing rod in which another rod is connected to the tip side of the second rod, the second rod is inserted into the first rod (inserted state) and pulled out (stretched). In the state), the second rod body and the first rod body can be freely fitted, and the fishing rod can be adjusted in length. Here, the second casing is fitted to the buffer layer of the first casing at the base end portion outer peripheral surface and the tip end end outer peripheral surface in the inserted state and the stretched state, respectively. At this time, since the buffer layer softer than the main body portion of the first casing is appropriately deformed so as to be fitted to the base side and the tip side of the second casing, these three diameters must be precisely matched. Is not required.
[0010]
Furthermore, there is no need to adjust the outer diameter of the tip of the second rod, and the outer peripheral surface of the tip of the second rod is adjusted to reduce the outer diameter or processed to increase the outer diameter ( For example, it is not necessary to overcoat the paint to increase the diameter), so that the appearance of the second casing is not deteriorated.
[0012]
The connecting structure of the casings according to the invention 2 is the structure of the invention 1, wherein the first casing body part is formed from a fiber reinforced resin obtained by impregnating a reinforcing fiber with a synthetic resin, and the buffer layer forms the body part. It is formed from a fiber reinforced resin that is softer than the fiber reinforced resin or a synthetic resin that does not include the reinforced fiber.
In this case, since the buffer layer is formed of a predetermined material with respect to the fiber reinforced resin forming the main body, a softer property than the main body is produced. Here, “fiber reinforced resin softer than the fiber reinforced resin forming the main body” means that the tensile strength of the reinforced fiber contained in the fiber reinforced resin is higher than the tensile strength of the reinforced fiber included in the fiber reinforced resin forming the main body. Mean small.
[0013]
The connecting structure of the casings according to the invention 3 is the structure of the invention 2 , wherein the buffer layer is formed of a fiber reinforced resin obtained by impregnating a nonwoven fiber or polyester fiber with a resin.
The connection structure of the frame which concerns on invention 4 is a structure of invention 1, Comprising: A buffer layer is a pipe-shaped elastic body. In this case, a pipe-like elastic body as a separate member from the main body portion of the first housing is disposed at a predetermined position after the main body portion is formed.
[0014]
Connecting structure of the rod body according to the invention 5, fluff be any structure of the invention 1-4, the buffer layer peripheral surface, fine plurality of projections which are roughened by brushing, or by brushing It is formed in a plurality of fine irregularities. In this case, the buffer layer whose inner peripheral surface is fluffed by brushing is more flexible and fits smoothly into the predetermined part of the second casing.
[0015]

On the other hand, a top guide 6 is attached to the end of the tip of the tip 5 and the fishing line L from the reel 7 passes through the fishing line guide G and the fishing line introduction port 9 and is guided to the fishing line passage. 6 leads to the outside.
[0017]
As shown in detail in FIGS. 2 to 4, the main shaft 1 includes a cylindrical main body 11 and a buffer layer 12 that is formed on the inner peripheral surface of the tip side end of the main body 11 and is softer than the main body 11. As will be described in detail later, the main body portion 11 is obtained by winding a main body prepreg made of a fiber reinforced resin obtained by impregnating a reinforced fiber such as a carbon fiber with a synthetic resin around a core material, and is tapered toward the tip side. This is a cylindrical member formed with a taper. On the other hand, the buffer layer 12 is formed from a soft prepreg that is softer than the main body prepreg, and is integrated with the main body portion 11 during firing. The inner peripheral surface of the buffer layer 12 is brushed by a metal brush or the like to be uneven, and a plurality of fine protrusions 12a are formed.
[0018]
The former upper collar 2 is a cylindrical member formed with a taper that tapers toward the tip side obtained by firing a predetermined prepreg in the same manner as the former collar 1. As shown in detail in FIG. 5, a first fitting portion 2 a formed so as to have a larger diameter than the other portion is formed near the tip side from the center in the length direction of the upper collar 2, The metal ring R is arrange | positioned at the tip side of 1 fitting part 2a. The outer diameter of the first fitting portion 2a is formed to be substantially the same as the outer diameter of the heel side end portion (second fitting portion 2b).
[0019]
(Manufacturing method of Genroku 1)
The Marshal 1 is manufactured as follows.
As shown in FIG. 6, first, a mandrel 100 having a predetermined taper is prepared, a release material or the like is applied to the outer peripheral surface thereof as necessary, and a release tape is wound around. Then, the soft prepreg P1 for forming the buffer part 12 is wound around the tip side end part. The soft prepreg P1 is, for example, a sheet or ribbon in which a fiber having a relatively low tensile strength such as polyester fiber is aligned in one direction and impregnated with a synthetic resin, or a non-woven polyester fiber is impregnated with a synthetic resin What was processed into the shape is illustrated. Or what consists only of synthetic resin which does not contain a fiber may be sufficient. This soft prepreg P1 is wound around the end of the mandrel 100 in the length direction of the mandrel 100 in the range of 5 to 30 mm.
[0020]
After winding the soft prepreg P1 in this way, the main body prepreg P2 for forming the main body portion 11 on the soft prepreg P1 and the mandrel 100 is wound. The main body prepreg P2 is formed by impregnating a synthetic resin into carbon fiber, glass fiber, or the like into a sheet shape or a ribbon shape, and the fibers are aligned in one direction. In general, the main body prepreg P2 is formed by sequentially winding a plurality of main body prepregs P2. For example, the main body prepreg P2 that is wound first uses a fiber in which the fibers are oriented in the circumferential direction of the mandrel 100. Further, the main body prepreg P2 that is further wound around the mandrel 100 can be used in which the fibers are oriented in the length direction.
[0021]
After winding the soft prepreg P1 and the main body prepreg P2, if necessary, a protective tape is further wound around the outer periphery, and this is fired in a high-temperature furnace. Thereafter, the mandrel 100 is pulled out, the protective tape, the release tape, etc. are sequentially peeled off, surface treatment is performed, and both ends are cut into appropriate lengths to produce the main bar 1.
In the case of a through-through rod constructed in this way, the tip side rod body is sequentially pulled out when used, and the collar side outer peripheral surface of the tip side rod body is fitted to the tip side inner circumferential surface of the rod side housing. It is fixed and used as a single fishing rod. Further, when the housing is stored, the housing is inserted into the housing on the heel side sequentially from the tip cage 5 while releasing the fitting of each housing to make a compact state.
[0022]
Furthermore, the former upper rod 2 and the former rod 1 can be fitted and fixed in both the housed state and the extended state, and fishing can be performed by adjusting the entire length of the fishing rod. That is, as shown in FIG. 5 (a), the upper fitting 2 is fitted into the buffer layer 12 of the original fitting 1 in the housed state, as shown in FIG. 5 (b). Thus, in the extended state, the second fitting portion 2b is fitted to the buffer layer 12 of the original upper collar 1. Here, since the buffer layer 12 that is softer than the main body 11 of the heel 1 is appropriately deformed so as to be fitted to the heel side and the tip side of the heel 2, the first fit of the heel 2 Sufficient fitting stability can be produced without requiring that the outer diameter of the portion 2a, the outer diameter of the second fitting portion 2b, and the inner diameter of the buffer layer 12 be precisely matched.
[0023]
In particular, the inner circumferential surface of the buffer layer 12 has a plurality of fine unevenness 12a is formed by a brush process, further smoothly enough to fit the first fitting portion 2a and the second fitting part 2 b.
[Second Embodiment] A second embodiment of the present invention will be described below with reference to the drawings.
[0024]
As shown in FIG. 7, the fishing rod employing the second embodiment of the present invention includes a marine rod 21, a middle rod 22 coupled to the tip side of the former rod 21, and a tip coupled to the tip side of the middle rod 22. And a ridge 23. These marshmallows 21 to 23 are pierced tubular members formed from prepreg or the like obtained by impregnating carbon fiber or glass fiber with synthetic resin. And as shown in FIG. 8, the spigot core 30 is arrange | positioned in the connection part of each casing, and each casing is connected by what is called a spigot joint.
[0025]
The main rod 21 has a reel sheet 24 formed on the outer peripheral surface to which a reel (not shown) can be detachably attached, and a grip 25 is disposed at an end of the flange side. Further, a plurality of fishing line guides 26 are arranged at predetermined intervals on each rod body, and a top guide 27 is arranged at the tip end of the tip rod side 23. Then, the fishing line from the reel is sequentially guided to the fishing line guide 26 and is guided to the outside from the top guide 27 on the tip side.
[0026]
As shown in FIG. 8, as in the first embodiment (see FIG. 2), the base rod 21 is formed on the cylindrical main body portion 21 a and the inner peripheral surface of the tip end portion of the main body portion 21 a and is softer than the main body portion 21 a. And a buffer layer 21b. The main body portion 21a is obtained by winding and firing a main body prepreg made of a fiber reinforced resin obtained by impregnating a reinforcing fiber such as carbon fiber with a synthetic resin around a core material, and having a tapered shape that tapers toward the tip side. It is a member. On the other hand, the buffer layer 21b is formed of a soft prepreg that is softer than the main body prepreg, and is integrated with the main body portion 21a during firing. The inner peripheral surface of the buffer layer is brushed with a metal brush or the like to be uneven, and a plurality of fine protrusions are formed.
[0027]
As shown in FIG. 8, the middle rod 22 is a cylindrical member formed with a taper that tapers toward the tip side formed by firing a predetermined prepreg in the same manner as the main rod 21. In addition, a spigot core 30 (corresponding to a fitting male part) is inserted and fixed to the heel side of the middle collar 22. The inlay core 30 is a cylindrical member formed of a predetermined prepreg, similar to the base rod 21 and the center rod 22. It is formed so as to match, and is inserted into the base side of the intermediate collar 22 and fixed with an adhesive or the like.
[0028]
In addition, the connection part of the middle rod 22 and the head rod 23 is also the same as the connection portion of the main rod 21 and the middle rod 22, and the description thereof is omitted.
In the fishing rod constructed as described above, the housings are disconnected and stored as individual rods when stored. When used as a single fishing rod, for example, in the case of the main rod 21 and the middle rod 22, the spigot 30 on the base side of the middle rod 22 is inserted and fixed to the tip side of the main rod 21. Use it. At this time, the buffer layer 21 b that is softer than the main body 21 a of the base rod 21 is appropriately deformed so as to fit into the spigot core 30. For this reason, the base side outer diameter of the spigot core 30 and the buffer layer inner diameter of the base bar 21 do not require precise matching, and a stable connected state can be produced relatively easily.
