Description

  The present invention provides a swing rod and a telescopic member that form a mating portion that holds the small-diameter housing and the large-diameter housing in an expanded state by press-contacting the outer peripheral surface of the small-diameter housing and the inner peripheral surface of the large-diameter housing. It relates to the formula swinging pad.

In this type of swing rod, in order to hold the small-diameter housing and the large-diameter housing in an extended state, the inner periphery of the tip-side end portion of the large-diameter housing is provided on the outer peripheral surface of the base-side end portion of the small-diameter housing. An uneven surface layer was formed in pressure contact with the surface. This uneven surface layer is composed of the same resin paint as that applied to the outer peripheral surface of the small-diameter casing or large-diameter casing as a decorative paint. It had a shape.
By forming the protrusions in this way, moisture can move between the protrusions, and thus has the following advantages.

For example, the outer peripheral surface of the base end portion of the small-diameter casing is formed as a flat surface, and the entire outer peripheral surface is formed so as to be in pressure contact with the inner peripheral surface of the tip end portion of the large-diameter casing. Then, when moisture enters the parts that are in pressure contact with each other, the pressure contact state becomes stronger, and a so-called fixed state appears in which the small diameter casing cannot be returned to the original contracted state.
On the other hand, when the protrusions are formed, the moisture moves and disappears between the protrusions even if moisture enters, and the moisture hardly appears in a fixed state.

JP-A-6-205626 (paragraph numbers [0018], [0019], FIGS. 1 and 3)

However, since the protrusion is formed by applying the same resin paint as the decorative paint applied to the outer peripheral surface of the small-diameter casing, the hardness of the protrusion is not sufficient, and in use in a short period of time The function can be maintained, but the projections may be worn out in long-term use.
As a result, the pressure contact between the outer peripheral surface of the small-diameter housing and the inner peripheral surface of the large-diameter housing becomes closer due to abrasion of the projections, etc., and the intrusion of moisture is not sufficient, and the sticking phenomenon can be completely wiped off. It was not.

  An object of the present invention is to provide a swing rod that can be used comfortably by avoiding the sticking phenomenon even in the case of long-term use by appropriately selecting the surface hardness in the mating portion. is there.

And is wound around the mandrel 6 as the first main pattern 15A to form the first layer Aa.

  Similarly, the prepreg sheet in which the reinforcing fibers c are arranged in the vertical axis direction is cut into a predetermined shape and wound around the mandrel 6 as the second main pattern 15B to form the second layer Ab. The third layer Ac as the outermost layer is formed by cutting a prepreg sheet in which reinforcing fibers c are arranged in the circumferential direction like the first layer Aa into a predetermined shape to form a third main pattern 15C. It is configured to be wound around a mandrel 6.

  As shown in FIG. 3 (a), the heel side reinforcement on the outer surface of the third layer Ac is shorter at the heel side end and the buttock side end than in the first main pattern 15A or the like. The pattern 12A and the buttock side reinforcement pattern 12B are wound to reinforce at the heel side end and the buttock side end. The prepreg used in the heel side reinforcement pattern 12A and the heel side reinforcement pattern 12B is impregnated with an epoxy resin, but the reinforcing fibers c are arranged in a cloth shape and arranged in the circumferential direction. Those having a larger number of reinforcing fibers c are used.

As the reinforcing fibers c, glass fibers and boron fibers can be used in addition to carbon fibers, and epoxy resins, phenol resins, and the like can be used as thermosetting resins. As the resin to be impregnated, a thermoplastic resin can also be used. Further, as the reinforced fiber c of the prepreg, a carbon fiber having a tensile elastic modulus of 20 to 60 ton / mm ² for the main pattern and a tensile elastic modulus of 10 to 40 ton / mm ^{2 for} the reinforcing pattern is used. It will be.

Specifically, UV (ultraviolet curable)
Paint is used.

In addition, since the UV paint has a large shrinkage force at the time of molding, if the resin paint selected as the surface coating layer 3 is not sufficient in condensation resistance, it is necessary to select another high-performance paint.
Here, in the acrylic urethane resin coating material used for the surface coating layer 3, the pencil core hardness is about 2H in a state of being cured after the construction.
On the other hand, the UV paint exhibits a hardness that the pencil core hardness exceeds 4H in a cured state after the construction. Spray paint, handling paint, etc. are adopted as the form of construction of this paint.

It is configured to be switchable to the drawn-out extended state, and is provided with a holding mechanism C that holds the contracted state.

The holding mechanism C that holds the contracted state will be described. As shown in FIG. 4, a retainer 11B that holds the base end 10A of the base 10 is fitted and fixed to the rear end of the base rod 11, and the end plug 7 is screwed to the holder 11B. . A receiving rubber 8 for preventing the tip heel or the like from coming out of the buttock of the base rod 11 is inserted and fixed at the tip of the butt plug 7 to constitute a mechanism for holding the base 10 in a contracted state. A holding surface 11b for holding the heel-side end portion 10A of the original upper 10 is formed on the distal end side from the mounting portion of the receiving rubber 8 in the holding tool 11B, and as shown in FIG. By fitting and holding the original side end portion 10A on the holding surface 11b, the original upper portion 10 can be held in a contracted state.
Here, the holder 11B and the uneven surface layer 9 formed on the base end portion 10A of the base 10 constitute a holding mechanism C that holds the contracted state of the base 10.

As shown in FIG. 4 (b), the base 10 is pulled out from the base 11, and the uneven surface layer 9 of the base end 10 </ b> A of the base 10 is used as the inner periphery of the base end 11 </ b> A of the base 11. It is possible to hold the original 10 in an extended state by pressing the surface. As described above, the uneven surface layer 9 is formed using UV paint. Here, the concave-convex surface layer 9 of the heel side end portion 10A of the base 10 and the inner peripheral surface of the heel side end portion 11A of the base rod 11 constitute a mating portion B that holds the stretched state of the base 10 To do.

As described above, the configuration of the matching part B has been described. Here, the test of the point that the configuration of the present invention can effectively avoid the sticking phenomenon of the mating portion B will be described.
A test apparatus for obtaining data of Tables 1 and 2 is shown in FIG. 5, and the base 10 is fitted to the base 11 and supported by being suspended. The fitting force between the former rod 11 and the former upper 10 is initially set to 5 kg.
The above data is obtained by measuring the movement amount L of the main bar 11 in a state where the weight Wh is dropped from the height H with respect to the main bar 11 and received by the receiving flange 2D formed on the main bar 11. .

Whether or not the falling amount of the weight Wh can be changed stepwise from 80 mm to 180 mm, the moving amount (shortened dimension) L1 is measured, and whether or not the moving state can return to the initial state before dropping the weight Wh = 1 kg. Is measured.
In other words, the dimension to be measured is that the weight Wh is dropped from the predetermined height (dimension L2) of the mating portion B in a state in which a static load of 1 kgf is applied and the base 10 is pulled out from the base 11 and the predetermined height. The dimension (shortened dimension) L1 of the main fence 11 that has moved in this case and the dimension (dimension after dropping) L3 of the mating portion B after dropping calculated from both dimensions.

  It was measured whether it was possible to return to the initial state from the stretched state, whether it was in a so-called fixed state, both of which were not difficult to return to the original state, It can be seen that it was possible to provide the mating part B that is less likely to fall.

As described above, the fishing rod used for the test has the uneven surface layer 9 formed using UV paint on the heel side end portion 10A of the original 10 as a product of the present invention.
On the other hand, as a conventional product (painted projecting part), a kite in which an uneven surface layer 9 is formed by spraying a decorative paint on the outer peripheral surface of the kite side end 10A of the base 10 is used.
The decorative paint used is as follows. A rubber-based paint with rubber having a high softness compared to urethane resin or the like is used. As the rubber paint, a soft polyester polyurethane resin paint is used. This paint is commercially available under the trade names “Senosoft” and “Senosoft II” manufactured by Kashu Corporation.

As a test method, after performing a zoom endurance test, the same enlargement test was performed again and the data was collected.
The zoom endurance test refers to repeatedly performing a state in which the base 10 is contracted into the base 11 and a state in which the base 10 is pulled out from the base 11, and is performed by manually expanding and contracting the base 10. It is.

The meanings of the judgment symbols are as follows.
○ ········································································································· Since it is fixed, it cannot be restored manually. If you use it, you can return it)

The evaluation of the drop test is as follows.
(1) In the conventional product, a good return state is not exhibited at the time of 100 mm, and the fixing phenomenon has already started at the time of 150 mm. Therefore, the following drop distance test is not performed.
On the other hand, in the product of the present invention, a satisfactory return state is still maintained at the time of 120 mm, the fixing phenomenon has not been reached even at the stage of 160 mm, and the fixing phenomenon has been reached only at the stage of 170 mm.

Therefore, the product of the present invention exhibits good performance against the sticking phenomenon even after the zoom endurance test.
From the above, it was possible to provide a fishing rod in which the sticking phenomenon hardly occurs even after long-term use.
