Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing rod having a structure for joining adjacent rods in a swing-out manner.
Therefore, not all of the rods need to have the swing-out joint structure.

[0002]

2. Description of the Related Art In general, the surface of each rod of a fiber reinforced resin fishing rod is coated to protect the rod and to decorate the rod. Further, in order to bring out an appearance different from that of painting, decorations having a mirror-like (metallic) appearance by physical vapor deposition such as ion plating are also performed. On the other hand, fishing rods are also required to be reduced in weight and the like, and attempts are being made to reduce the polarization force and reduce the cost by omitting a coating layer or a vapor deposition layer.

[0003]

However, when the rod body made of fiber reinforced resin is exposed as it is without painting, if it is rubbed by any member, it is immediately scratched, and the scratch is made of a matrix synthetic resin. Any flaws in the reinforcing fibers. In particular, when the reinforcing fiber is damaged, it is not only a matter of appearance but also has a great influence on the strength of the rod. This is particularly problematic in the current situation where the ratio of matrix resin is reduced for weight reduction. On the structure of the fishing rod, in a fishing rod having a swing-out joint structure, the front rod is rubbed by the inside of the distal end of the original rod every time the rod expands and contracts, and the surface of the front rod is There is a great risk that the device will be damaged or damaged. Scratches and damages on the surface, even to varying degrees, are the same not only for unpainted rods, but also for painted and evaporated rods,
In particular, the deposited layer is easily damaged. Therefore, the present invention
It is an object of the present invention to prevent a front rod from being scratched or damaged due to friction between a source rod and a front rod in a fishing rod having a swing-out joint structure.

[0004]

SUMMARY OF THE INVENTION In view of the above object, according to the first aspect of the present invention, the leading rod and the leading rod are spliced together and project inside the tip of the leading rod. The present invention provides a fishing rod characterized by having a swing type joint structure in which a sliding member having a smaller coefficient of friction than the inner surface of the main body member of the original rod is located on the center side of the rod. If the rod is made of fiber reinforced resin, fluororesin, acrylic silicon,
The sliding member can be made of a material such as silicon. In the swing-out type joint structure, the part where the front rod is most rubbed is the inner part of the tip of the former rod, and therefore, a sliding member having a smaller coefficient of friction than the inner surface of the former rod body is used here. If it is located at the center of the rod and protrudes from the inner surface of the rod, when the surface of the leading rod comes into contact, it comes into contact with this sliding member and occurrence of scratches and the like can be reduced.

According to a second aspect of the present invention, there is provided the fishing rod according to the first aspect, wherein a smoothness of a center side surface of the rod of the sliding member is about 0.1 μm or less in center line average roughness. The center line average roughness is the roughness (Ra) defined in JIS standard B0601.
It is. If the surface of the sliding member having a small friction coefficient is sufficiently smooth to have a center line average roughness of about 0.1 μm or less, scratches and the like are further prevented. According to a third aspect of the present invention, a part or the entire outer peripheral surface of the front rod is unpainted.
Or the fishing rod of 2 is provided. As described above, since the rod having an unpainted area can be seriously affected by the damage, the invention of claims 1 and 2 is important.

According to a fourth aspect of the present invention, there is provided the fishing rod according to any one of the first to third aspects, wherein the sliding member is provided via an elastic member having more elasticity than the sliding member.
If the sliding member is provided through an elastic member having elasticity, even if the leading rod comes into contact with the sliding rod, the pressing force is absorbed to reduce the pressing force on the surface of the leading rod. However, this can further reduce the frictional force and prevent scratches and the like.

According to a fifth aspect of the present invention, in a state in which the front rod is swung with respect to the original rod, the distal end position of the front rod joint that presses against the inner surface of the original rod is adjusted to the sliding position. 5. The member is located closer to the original side than the rear end position of the projecting portion.
The fishing rod according to any one of the above items is provided. If the distal end position of the front rod-joint is located closer to the original position than the rear end position of the protruding portion of the sliding member, the sliding member is not damaged by the front rod-joint when it swings out. Only needs to be done.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail based on embodiments shown in the accompanying drawings. FIG. 1 is a sectional view showing the vicinity of a swing-out joint of a fishing rod according to the present invention.
Is a partially enlarged view of FIG. Front rod 10 and original rod 12
And are spliced together. Each rod is made of a fiber reinforced resin in which a synthetic resin such as an epoxy resin is reinforced with a reinforcing fiber such as carbon fiber. In this embodiment, the outer periphery of the front rod 10 is unpainted, and the fiber reinforced resin itself is used. Is exposed.

A ring-shaped base 14 made of a material such as metal harder than a fiber-reinforced resin is provided on the outer side of the distal end of the original rod 12 so that the rod 12 hits a rock or the like. In addition, the tip is prevented from being damaged. Further, in this embodiment, the sliding member 16 made of the above-described material having a smaller coefficient of friction than the inner surface 12A of the original rod body member is spray-coated by spray gun and brush-coated over the inside and the distal end portion of the rod 12. , Dipping or the like. It is preferable that the opening shape of the distal end portion of the original rod provided with the sliding member 16 has a shape that is chamfered in a widened shape as shown in the figure.

However, what is essential is that the sliding member 16 is provided in a protruding manner inside the distal end portion. Thereby, when the front rod 12 is pulled out or stored, even if the outer periphery of the front rod 10 is rubbed by the inside of the distal end portion of the original rod 10, the frictional force is small, and The outer periphery can be prevented from being scratched or damaged.

The thickness t of the sliding member 16 inside the tip of the original rod, ie, the amount of protrusion from the rod body inner surface 12A is 10
It is preferably about 20 μm. The length L from the rod tip is preferably about 5 mm. The smoothness of the surface of the sliding member 16 facing the outer periphery of the front rod 10 is preferably about 0.1 μm or less in center line average roughness. This further prevents scratches and the like.

The leading end position P0 of the joint portion 10T of the front rod 10 that is pressed against the inner surface 12A of the original rod in the swinging state is as follows.
It is located on the original side from the rear end position of the sliding member 16 and is about 20 to 50 mm from the tip of the front rod 12.
Therefore, when it swings out, the sliding member 16 does not have to be damaged by the front rod-joint 10T.

FIG. 3 shows another embodiment of the fishing rod according to the present invention.
Is formed, and the member 18 is buried therein, and protrudes from the inner surface 12A of the original rod 12 to the center side of the rod, that is, the side facing the front rod 10 by the dimension t. As described above, the sliding member 16 'made of the above-described material is provided. Member 1
Numeral 8 is an elastic member such as rubber which is more elastic than the sliding member 16 '. As a result, the outer circumference of the front rod 1
0 even if rubbed by the sliding member 16 'inside the tip
The frictional force is small, so that the outer circumference of the front rod can be prevented from being scratched or damaged, and furthermore, the frictional force can be further reduced by the action of the elastic member, so that the scratches can be more effectively prevented.

As shown in FIG. 3, in addition to the form in which the elastic member 18 and the sliding member are completely separated from each other, particles of the sliding member are mixed in the base material such as the elastic member, and the base material is located on the center of the rod. On the surface of
The sliding member particles may be in a protruding form. Also,
In FIGS. 2 and 3, the sliding member is provided annularly on the entire circumference inside the rod end, but may be provided on the inner circumference in a discrete manner.

Further, in the case of the embodiment shown in FIG. 2, the sliding member does not have to be provided directly on the rod body member as in the embodiment shown in FIG. 3, and any other member can be interposed therebetween. Good. For example, it is a member or the like that improves the adhesion of the sliding member. Also, in the case of the embodiment shown in FIG.
Or any other member may be interposed between the elastic member and the sliding member 16 '. Further, the front rod 10
The present application is established even if the surface of the substrate is painted or the like.

If the above-mentioned sliding member has a lower hardness than the surface of the front rod and is more easily worn than the surface,
This prevents damage to the surface of the front rod. For example, when the front rod is unpainted, the hardness of the sliding member is preferably 7H or less. Depending on the design of the fishing rod, each rod may be designed to be particularly thin in order to improve the bending performance even at the joint area between the leading rod and the former rod. To avoid this, the hardness of the sliding member may be reduced to about 4H or less, and the hardness may be sufficiently reduced. The coating on the surface of the rod is performed by spraying, brushing, dipping, or the like, and the coating includes resin such as epoxy, polyurethane, acryl, acrylic silicon, silicon, and the like.
