Description

  The present invention relates to a device (a fishing rod sticking release device) used for releasing the sticking of a seam of a fishing rod.

In a fishing rod, the seam often hardens and cannot be removed due to water or scattered bait that has entered the seam, and such sticking at the seam occurs both in the case of a parallel rod and in the case of a swing rod.
In particular, in the case of a fishing rod, when a fish catches, the whole fishing rod is pulled to the rod tip side, and at the joint of each node of the rod, the outer peripheral surface of the node located on the rod tip side and the inner part of the node located on the rod base side The force to adhere to the peripheral surface works. When the force to keep such seams in close contact continues to work, the outer peripheral surface of the rod-end side node and the inner peripheral surface of the rod-side side node bite into each other, and the seam is firmly adhered and does not move with each other. And sticking occurs. In particular, in each section near the pole tip, if the rod is immersed in water and power is applied in a state where water has entered the seam, the gap between the two contact surfaces of the seam becomes slippery, so biting is more The seams are more likely to occur, and the seams are more likely to be firmly fixed. Under the hot summer sun, the seams are often hardened and cannot be removed due to seawater, sprinkling bait, or the like.
If sticking occurs at the seam of the rod in this way, after fishing, when trying to shrink each knot, there is a problem that the seam does not move and the rod can not be stored, in which case the sticking is released In order to do this, a large force is applied to the seam, but when the force is applied, the rod or guide may be damaged, and when it cannot be released, the rod is currently brought into a fishing equipment shop.

  Heretofore, as a method of releasing the sticking of the seam of the fishing rod, it has been proposed to provide a circumferential groove along the circumferential direction on the outer peripheral surface of the rear end of each node arranged inside at the seam of each node. ing. This circumferential groove serves as an escape point for water when water enters the seam, so it suppresses slippage between both contact surfaces of the seam, and the contact area of the inner and outer peripheral surfaces at the seam is reduced, so that seam sticking occurs Even if such a circumferential groove is provided, even if such a circumferential groove is provided, when a large tensile force is applied to the seam when used for actual fishing, a strong adhesion occurs There was a problem that would.

As an instrument used to release the sticking of a fishing rod, for example, Patent Literature 1 listed below discloses a plurality of belts made of a flexible material having a high coefficient of friction with the rod surface, which can be wound around the outer periphery of the rod. There is disclosed a swing rod sticking release device having a high elastic modulus thread-like body disposed between a plurality of belts. However, in the case of this release device, since the outer diameter of the node located on the rod tip side is smaller than the outer diameter of the node located on the rod base side, the belt of the release device is brought into close contact with the joint portion of the node. There is a problem in that it is difficult to wind in a folded state, and the winding on the node side located on the pole tip side becomes loose. Also, in the case of this release device, two rubber belts must be wound simultaneously along the outer periphery of the joint, and in order to generate a large torsional moment, increase the number of windings of the belt. It was necessary to increase the winding diameter.
Under the current situation as described above, there is a demand for a device that can be easily attached to a rod and that can easily and reliably release the seam fixation by itself without damaging the rod or the guide.
