BACKGROUND OF THE INVENTION
The present invention relates to a fishing rod used for fishing.
[0002]
[Prior art]
[About fishing rods]
In a fishing rod called a swing type in a conventional fishing rod, a plurality of cylindrical rods can be inserted into the rod-side housing sequentially from the tip-side rod. When fishing, each chassis is pulled out to the tip side sequentially and fitted and fixed to be used as a single chassis. On the other hand, at the time of storage, the body on the tip side is sequentially stored in the body on the base side to make it compact.
[0003]
Some fishing rods of this type have been devised so that fishing can be performed by changing the overall length of the rod. The fishing rod of the fishing rod devised in this way has a first fitting fixing portion that is formed on the inner peripheral surface of the tip side end portion to be slightly smaller in diameter than the other portions and can be fitted and fixed to the fishing rod side end portion of the upper upper rod. And a second fitting / fixing portion which is disposed in the heel side end portion and can fit and fix the heel side end portion of the upper upper heel. And, the state where the former bowl connected to the tip side of the marshal is pulled out to the tip side (hereinafter referred to as “stretched state”) and the state where the former bowl is inserted into the former side (hereinafter referred to as “storage state”) ) And the former upper collar are fitted and fixed to the first fitting and fixing portion and the second fitting and fixing portion, respectively. Thus, the main rod and the upper rod can be fitted and fixed to each other in both the “extended state” and the “stored state”, and fishing can be performed by changing the length of the entire rod according to the situation.
[0004]
[About fishing line guide]
Further, a fishing line guide for guiding the fishing line between the reel and the tip while supporting the fishing line is provided on the outer peripheral surface of the rod body of the fishing rod used for fishing. This fishing line guide has a ring-shaped ring part into which a ceramic ring is inserted and a fishing line can be inserted, a leg part extending from the ring part in the direction of the body, and a body formed with the body inserted through the end of the leg part. And a cylindrical fixing portion fixed to the peripheral surface.
[0005]
[Problems to be solved by the invention]
In fishing rods designed so that fishing can be performed by changing the overall length of the conventional rod, the outer periphery of the base end of the upper rod itself is connected to the first fitting fixing portion and the second fitting fixing portion of the original rod, respectively. The surface is fitted, and the base and the top are fixed. Thus, the heel side end of the upper collar is used for fitting and fixing not only in the extended state but also in the housed state, so that the fitting force may be reduced if it is used for a long time. In general, the body has a taper with a smaller diameter on the tip side, and precise fine adjustment of the fitting fixing part is required to produce a sufficient fitting force in either the extended state or the stored state. Therefore, a complicated process is required for the adjustment.
[0006]
Also, with regard to the fishing line guide, the fishing rod body is generally tapered so that its diameter decreases toward the tip of the fishing line. Therefore, the fishing line guide is precisely adjusted so that the inner diameter of the fixing portion matches the outer diameter of the fishing body at the position where the fishing line guide is fixed. There is a need.
[0007]
An object of the present invention is to provide a fishing rod that can be easily adjusted even in a portion that requires precise adjustment.
[0008]
[Means for Solving the Problems]
A fishing rod according to a first aspect of the present invention is a fishing rod used for fishing, wherein the first rod, the second rod connected in a swinging manner to the tip of the first rod, and the base end of the first rod is fixed to the inner peripheral, have a fitting fixable inner peripheral surface rod source side outer periphery of the second Sao member allows deformation when heated above the glass transition point, is cooled below the glass transition point And a cylindrical member made of a shape memory polymer that maintains a deformed shape, and the cylindrical member is formed so that an inner diameter is smaller than an outer diameter on the base side of the second casing and is heated to the glass transition point or more. In this state, the second casing or a member having a dimension equivalent to the outer diameter of the second casing is inserted to expand the diameter, and then cooled to the glass transition point or less to cool the second casing. It is formed so that it may correspond to the former side outer peripheral surface.
[0009]
In this fishing rod, in the stretched state in which the second rod is pulled out toward the tip of the first rod, the rod-side outer peripheral surface of the second rod is connected to the first rod like a normal fishing rod. Fit and fix to the inner peripheral surface of the tip side. And in the storage state which inserted the 2nd housing in the 1st housing, the base side outer peripheral surface of a 2nd housing is inserted in the cylindrical member of a 1st housing, and it fixes by fitting.
[0010]
Here, the cylindrical member to which the base side outer peripheral surface of the second casing fits can be adjusted easily by the following procedure, although it is necessary to precisely adjust the inner diameter thereof. That is, the cylindrical member is made of a shape memory polymer so that the inner diameter is slightly smaller than the planned inner diameter. Then, the cylindrical member is heated to the glass transition point or higher so as to be elastically deformable, and the second casing (or a member having an equivalent outer diameter) is inserted into the cylindrical member in a state in which the cylindrical member can be elastically deformed. While expanding the inner diameter of the cylindrical member, the inner diameter is precisely matched with the outer diameter of the second casing. Then, the shape is stabilized by allowing to cool to below the glass transition point.
[0011]
In addition, when the tubular member is repeatedly engaged with the second casing over a long period of time, the fitting force is reduced due to wear or expansion of the inner diameter. In such a case, the cylindrical member is again heated to the glass transition point or higher so that it returns to its original shape. By repeating the same operation, a good inner diameter can be set and a sufficient fitting force can be produced again. .
[0012]
In addition, the shape memory polymer used here is a property in which elasticity is increased above the glass transition point and free deformation is possible, and the deformed shape is maintained when cooling below the glass transition point while applying deformation and restraining the load in this state. (Shape fixability), and a synthetic resin having a property (shape recoverability) that returns to the previous shape when the load is released by heating above the glass transition point.
[0013]
A fishing rod according to a second aspect of the present invention is the fishing rod according to the first aspect, wherein the tubular member has a projecting portion projecting radially inward on the inner peripheral surface.
When this structure is used, the protruding portion of the cylindrical member is fitted to the second casing in the stored state, so that a gap is partially formed between the outer peripheral surface of the second casing and the inner periphery of the cylindrical member. The gap acts as a cushion, and a sufficient fitting force can be produced without excessive fine adjustment of the diameter of the cylindrical member or the fitting protrusion.
[0014]
A fishing rod according to a third aspect of the present invention is a fishing rod used for fishing, and a rod body, a ring portion into which a ceramic ring through which a fishing line is inserted is fitted, a leg portion formed continuously with the ring portion, and a tip of the leg portion And a fishing line guide having a substantially cylindrical fixing portion that is fixed to the peripheral surface of the fishing body in a state where the housing is inserted, and is disposed on the inner periphery of the substantially cylindrical fixing portion of the fishing line guide , the glass transition point or more And a sleeve made of a shape memory polymer that can be deformed when heated to below the glass transition point and maintain a deformed shape when cooled below the glass transition point , and the sleeve has an inner diameter smaller than the outer diameter of the casing. The casing is inserted in a state of being heated to the glass transition point or higher, and then cooled to the glass transition point or lower so as to match the peripheral surface of the casing. [0015]
In this fishing rod, although it is necessary to precisely adjust the inner diameter of the fixed portion of the fishing line guide with which the outer peripheral surface at a predetermined position of the rod is fitted, the adjustment can be easily performed by the following procedure.
[0016]
That is, the sleeve is made of a shape memory polymer so that the inner diameter is slightly smaller than the planned inner diameter, and this is fixed in the fixing portion. Then, the sleeve is heated to the glass transition point or higher so as to be elastically deformable, and in this elastically deformable state, a casing (or a member having an equivalent outer diameter) is inserted into a fixed part or sleeve to insert the inner diameter of the sleeve. The inner diameter is precisely matched with the outer diameter of a predetermined casing while expanding the diameter of. Then, the shape is stabilized by allowing to cool to below the glass transition point.
[0017]
Further, when the fishing line guide is used over a long period of time, the fitting force with respect to the frame decreases due to wear and expansion of the inner diameter of the fixed portion. In such a case, the sleeve is returned to its original shape by heating it again to the glass transition point or higher, so that a good inner diameter can be set by repeating the same operation, and a sufficient fitting force can be re-produced.
[0018]

The gap acts as a cushion, and a sufficient fitting force can be produced without excessive fine adjustment of the tubular member 20 to the protrusion 20a.
[0031]
[Third Embodiment]
Hereinafter, a third embodiment of the present invention will be described with reference to the drawings.
A fishing rod employing the third embodiment of the present invention, as shown in FIG. 6, has a rod body 31, and inserts a fishing line from a reel (not shown) to sequentially guide the fishing line to the tip side. The guide 32 is fixed to the peripheral surface of the housing 31 with a predetermined interval.
[0032]
The casing 31 is a tapered tubular member obtained by winding and firing a prepreg obtained by impregnating a synthetic fiber into carbon fiber or glass fiber around a mandrel. A plurality of such rods 31 are connected in a swing-out manner or a parallel manner to form a general fishing rod.
[0033]
6 and 7, the fishing line guide 32 supports a ring part 40 in which a ceramic ring R through which the fishing line is inserted is fitted, and a ring part 40 formed to extend from the ring part 40 toward the housing 31. And a substantially cylindrical fixing part 42 formed continuously at the tip of the leg part 41. A sleeve 43 is disposed and fixed on the cylindrical inner peripheral surface of the fixing portion 42.
[0034]
The ring portion 40 is a member made of a metal such as a Ti alloy or a Ti—Ni alloy. A hole penetrating in the axial direction of the fishing rod is formed, and a hard ceramic ring R is fitted and fixed to this hole. The fishing line from the reel is inserted through the ceramic ring R and is sequentially sent to the tip side. The leg 41 is also a member made of a metal such as a Ti alloy or a Ti—Ni alloy. The leg portion 41 supports the ring portion 40 and is connected to the fixed portion 42 at the other end.

The fixing portion 42 is a substantially cylindrical member that is fixed on the peripheral surface of the housing 31 in a state where the housing 31 is inserted, and is a similar metal member that is formed integrally with the leg portion 41. A pipe-shaped sleeve 43 is disposed on the inner periphery of the cylindrical portion of the fixing portion 42 and is fixed with an adhesive or the like. The sleeve 43 is a member made of a polyurethane-based or polyether-based shape memory polymer. For example, “Dialy” (trade name, manufactured by Mitsubishi Heavy Industries, Ltd.), which is a polyurethane polymer, can be exemplified, and the glass transition point is preferably set to about 50 to 70 ° C. The inner diameter is adjusted to match a predetermined outer diameter of the casing 31 as will be described later.
[0036]
In this fishing rod, although it is necessary to precisely adjust the inner diameter of the fixing portion 42 of the fishing line guide 32 with which the outer peripheral surface of the rod body 31 at a predetermined position is fitted, the adjustment can be easily performed by the following procedure. .
[0037]
The sleeve 43 is made of a shape memory polymer so that the inner diameter is slightly smaller than the planned inner diameter, and this is fixed in the fixing portion 42. Then, the sleeve 43 is heated to the glass transition point or higher so as to be elastically deformable, and in this elastically deformable state, the housing 31 (or a member having an equivalent outer diameter) is inserted into the sleeve 43 and the sleeve 43 While expanding the inner diameter, the inner diameter is precisely matched with the outer diameter of the predetermined casing 31. Then, the shape is stabilized by allowing to cool to below the glass transition point.
[0038]
Further, when the fishing line guide 32 is used over a long period of time, the fitting force with respect to the housing 31 is reduced due to wear and expansion of the inner diameter of the fixed portion 42. In such a case, since the sleeve 43 is again heated to the glass transition point or higher to return to the original shape, a similar inner diameter can be set by repeating the same operation, and a sufficient fitting force can be re-produced.
[0039]
