Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to fitting one mating surface for joining two rod members to the other mating surface while mating the other mating surface. On the surface
The present invention relates to a joint structure and a grip structure for a fishing rod of various types such as a swing-out type in which a fiber group for fitting and fixing the tip of the fishing rod is planted.

[Conventional technology]

As a joint structure of a fishing rod of this type, conventionally, in a swing-out type fishing rod, one in which a fiber group is planted by electro-deposition flocking on the inner fitting surface of the fitting surfaces for joining the rod materials. It is known (for example, Japanese Utility Model Publication No. 49-46558). In this case, there are the following advantages as compared with the case of fitting and joining the inner and outer fitting surfaces in contact with each other.

In other words, when fitting the inner and outer mating surfaces in contact with each other, if the mating surface gets wet with water or the like, a so-called sticking phenomenon occurs in which the contact part is in a vacuum state, and the mating surfaces are in the axial direction. It becomes very difficult or impossible to disengage the fitting by sliding it to the. Moreover, even when the fitting operation is performed excessively, the contact pressure between the inner and outer fitting surfaces becomes excessive, which makes it extremely difficult to release the fitting. On the other hand, when the fiber group is implanted, in the combined state where the inner and outer mating surfaces are fitted, the fiber group is interposed between the mating surfaces in a compacted state, so that the mating surface directly By avoiding contact, even when the mating surfaces are wet, the above-mentioned sticking phenomenon can be prevented and excessive close contact between the inner and outer mating surfaces can be prevented, and the mating surfaces slide in the axial direction. The mating can be easily performed by disengagement, and by lengthening the fiber implantation area of the fiber group, even if the mating operation is excessive, the mating can be easily unmated. You can

On the other hand, as the grip portion structure of the fishing rod, a belt-shaped body made of resin having hairs planted on the surface is wound at a position corresponding to the grip portion,
It is known that the outer peripheral surface is uneven to prevent slipping (for example, Japanese Utility Model Laid-Open No. 60-96023).

[Problems to be solved by the device]

However, in the above-described conventional joint structure, since the position regulation of the inner and outer fitting surfaces in the eccentric direction is performed only by the fiber group, there are the following drawbacks.

In other words, during the fitting operation, it is almost impossible to operate the rod material only in the axial direction, and the rod material is usually subjected to an eccentric operating force. Therefore, in the conventional structure, at the time of the fitting operation, the fibers that are planted in the inner fitting surface near the outer fitting surface due to the eccentricity of the rod material are strongly pressed against the outer fitting surface, When the bending angle at the root portion is large, the outer fitting surface is strongly slid and pulled.
As a result, excessive stress concentrates on the root portion of the fiber, and the root portion of the fiber deteriorates early and is easily cut. In addition, with a swing-out type fishing rod, when putting the previous rod inside the original rod,
Since the fluctuations of the rod to be sewn by the fiber group cannot be sufficiently suppressed, the sewage is not smooth, and the operation feeling of the sewage is bad.

In addition, for the fishing rod, in order to easily and quickly change the rod length according to the fishing technique, the original rod is configured to be an expandable and retractable rod member from a plurality of slidably fitted rod members. Among them, there is a front end portion of the outer one and a front end portion of the inner one, in which a fitting surface for matching for fixing them in a contracted state is formed. If the conventional structure is used as it is for the fitting portion of such a fishing rod (hereinafter, referred to as a zoom rod), the original rod is stretched,
Not only the above-mentioned drawbacks associated with the fitting operation are more likely to occur, but also the following inconveniences occur due to the high frequency of closing.

That is, during the fitting operation, the edge of the outer rod member at the angle between the front end surface and the inner peripheral surface pushes the root portion of the fiber. However,
The root portion of the fiber is hardly displaced even when pushed by the front edge. Therefore, when the edge of the outer rod material pushes the root portion of the fiber, the pushing force is hardly absorbed, and the edge acts to scrape the fiber from the root portion,
Easy to cut fibers.

On the other hand, in the case of the conventional grip structure, the uneven portion does not directly touch the palm due to the transplanted hair, and the grip feeling can be improved, but since the transplanted hair is provided over the entire surface of the grip, it is strong. In the gripped part,
The flock may be pressed and separated from the root part. Therefore, the long-term use resulted in a densely populated hair transplant state, and the hair transplant did not exhibit its function sufficiently.

An object of the present invention is to eliminate the above-mentioned conventional drawbacks.

[Means for Solving the Problems]

A feature of the joint structure of a fishing rod according to claim 1 of the present invention is that the rod member having the one mating surface is provided with a restricting portion for preventing contact between the mating surfaces. The point is that the fiber group is planted in a state of protruding radially from the regulating portion.

In the above-mentioned characteristic configuration, it is preferable that the restriction portion is arranged in a portion of the rod material adjacent to the fitting surface in the rod material longitudinal direction.

The characteristic structure of the grip portion structure of the fishing rod according to the present invention is that the outer peripheral surface of the grip portion of the fishing rod is formed into an uneven surface, and a fiber group is formed on the bottom surface of the concave portion of this uneven surface, and the tip of the fiber portion projects outwardly from the convex portion. It has been planted in.

[Action]

(Claim 1) During the expansion and contraction operation of the rod, the fiber group protruding from the restriction portion first comes into contact with the mating surface of the mating side, and the fitting pressure contact force changes gently with the fitting operation, so that it is soft. It is possible to obtain a feeling of operation, and it is possible to prevent the mating surface of the mating member from acting on the root portion of the fiber group by contact with the regulating portion.

(Claim 2) In the case of forming the restricting portion on the fitting surface at a position adjacent to each other in the longitudinal direction of the rod material, in order to form the fitting surface with high accuracy,
Since the rod material is manufactured in a state where the rod material portion forming the fitting surface is thick and the fitting surface is formed by grinding the peripheral surface of the rod material portion, it is generally adopted. By grinding with a portion of the thick-walled rod material left, the formation of the fitting surface and the formation of the restriction portion can be performed all at once.

(Claim 3) When the grip portion is gripped, the fiber group is interposed between the palm and the uneven surface to prevent the palm from directly touching the edge of the convex portion, and the fiber group serves as a cushion due to elastic deformation. To work. Moreover, due to the convex portion,
It is possible to prevent the palm or other objects such as other rods from hitting or rubbing the root of the fiber group.

[Effect of device]

Therefore, according to the joint structure of the present invention, it is possible to prevent the fiber group from being deteriorated or cut due to the joint, and to provide a feeling of operation for releasing the joint of the rod material by the fiber group coming into contact with the mating surface of the other side in advance. I was in good condition.

In particular, if the second aspect is adopted, the manufacturability can be improved.

Further, according to the grip portion structure of the present invention, the grip operation can be performed with a good feeling of operation and less fatigue, and deterioration and cutting of the fiber group can be prevented.
