Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for manufacturing a fishing rod with anti-slip protrusions.

(Prior Art) Generally, an anti-slip means is provided on the outer peripheral surface of a grip portion of a fishing rod to prevent the fishing rod from slipping with respect to a hand gripping the grip portion.

However, conventionally, as a means to stop fishing rods from slipping,
The rod body is made by wrapping prepreg made of high-strength fibers impregnated with synthetic resin, and thread is wrapped around the handle, or the outer periphery of the rod body is covered with cylindrical cork or a roughened surface. The fishing rod is constructed by fitting a heat-shrinkable tube into the fishing rod, and these anti-slip means prevent the hand gripping the fishing rod from slipping.

(Problems to be Solved by the Invention) However, in the case of winding the thread as in the conventional example described above, the winding work and the work of fixing the wound thread are complicated, the workability is poor, and the cost is high. In addition, those using cork or the tube have problems of poor workability and high cost.

In addition, it is difficult to form them only in the position where they have the highest anti-slip effect due to the relationship with the hand holding the fishing rod, and because they are formed all over the entire circumference, fish are unable to feed. There was an issue where the price was based on the sensitivity of the hit you felt when you held it in your mouth.

The present invention was invented in view of the above points, and the purpose is to use silk screen printing that can print even if the surface to be printed is curved, and by this silk screen printing, synthetic resin material can be applied to the rod body. By printing on the outer circumferential surface and forming a large number of anti-slip protrusions, these anti-slip protrusions can be easily formed, and can be formed only at positions where the anti-slip effect is highest in relation to the hand gripping the fishing rod. A pattern of a predetermined shape can be formed by the group of the anti-slip projections, and a decrease in sensitivity can be prevented, thereby making it possible to manufacture a fishing rod that is light and inexpensive.

(Means for Solving the Problems) According to the present invention, a rod body 1 is formed by wrapping a prepreg made of high-strength fibers impregnated with a synthetic resin, and on the outer peripheral surface of the rod body 1, A large number of anti-slip protrusions 2 are formed by printing a protrusion forming material by silk screen printing using a thick stencil having a thickness corresponding to the height of the protrusions having the anti-slip height.

(Function) The rod body 1, which is formed into a hollow cylindrical shape by wrapping prepreg, is supported on a support stand so that it can roll freely, and a frame body with a stencil is placed above the rod body 1. , put a protrusion forming material into this frame, rub the upper surface of the stencil with a squeegee, transfer the protrusion forming material from the transfer hole of the stencil to the surface of the rod body 1, and remove the protrusions attached to the rod body 1. A large number of anti-slip protrusions 2 are formed by drying the molding material.

(Example) The basic manufacturing method of the present invention uses a core metal having a molded part of a size corresponding to the inner diameter of the hollow rod body 1 which is inclined in a tapered manner. A sheet of prepreg impregnated with synthetic resin is wrapped around the outer periphery of the wrapped prepreg.
A narrow tape made of high-strength fibers impregnated with synthetic resin is wound spirally, and cellophane tape is spirally wrapped around the entire outer periphery including this tape layer to bind it. The prepreg is pressurized, heated in a heating furnace in this pressurized state, the synthetic resin in the wrapped prepreg is cured by this heating, and the core bar is then removed and the cellophane tape is peeled off to form the rod body. 1, and then a large number of anti-slip protrusions 2 having an anti-slip height are formed on the outer peripheral surface of the rod body 1 by printing a synthetic resin material by silk screen printing.

Therefore, the thickness of the silk screen printing corresponds to the height of the anti-slip projection 2 (for example,
A stencil 3 having a diameter of 0.3 mm) is used, a number of transition holes 31 corresponding to the number of the anti-slip projections 2 are formed in this stencil 3, and this stencil 3 is attached to a frame 4. In the embodiment shown in FIGS. 3 and 4, first, a clear paint made of epoxy resin is applied to the outer peripheral surface of the rod body 1 to form a base coat layer 11, and the surface of this base coat layer 11 is After printing a large number of synthetic resin anti-slip protrusions 2 by silk screen printing,
The surface of this anti-slip protrusion 2 and the anti-slip protrusion 2
A clear coating made of epoxy resin is applied to the surface of the base coat layer 11 on which no surface layer is formed, thereby forming the skin layer 12.

The rod body 1, on which the base coating 11 has been formed as described above, is supported horizontally on a support stand so that it can roll freely, and the frame body 4 with the stencil 3 is placed above the rod body 1. The stencil 3 is placed in contact with the surface of the rod body 1, and the upper surface of the stencil 3 is rubbed with the squeeze 5, and at the same time, the frame 4 is filled with an epoxy resin material. 4 in the horizontal direction, and the rod body 1 is rolled in conjunction with the movement of the frame 4, and the resin is transferred from the transfer hole 31 of the stencil 3 to the rod body 1 side by rubbing with the squeeze 5. The material is adhered to the surface of the base coating layer 11 of the rod body 1 to form a large number of anti-slip protrusions 2. Then, the frame body 4 is separated upward from the rod body 1, the rod body 1 is removed from the support base, and the anti-slip projections 2 are hardened, and then a clear paint is wrapped around the skin layer. 12 is formed.

Further, in the embodiment shown in FIGS. 5 to 7, a tapered portion 1b is provided at the tip of the grip portion 1a on the rod butt side, the diameter of which expands at a rate of change greater than the rate of change of the diameter on the tip side of the rod body 1. The grip portion 1a is formed into a straight rod shape with a large diameter, and the anti-slip protrusion 2 is provided on the grip portion 1a. Further, in this embodiment, the anti-slip protrusion 2 is provided in the reel seat mounting portion of the grip portion 1a. Specifically, a first anti-slip protrusion group (2a) is provided in a semicircular part excluding the part facing the strip-shaped reel seat 6, and a spinning ring attached to the seal sheet 6 and the reel seat together with the grip part 1a is provided. In order to prevent slipping when fishing by gripping the mounting legs of the reel, a second anti-slip protrusion group 2b is provided on the reel seat 6 slightly toward the bottom of the rod with respect to the mounting area of the reel seat 6. It is designed to prevent slipping when fishing with a double-shaft reel attached.In addition, among the first anti-slip protrusion group 2a, a contact portion 1c with the palm part extending from the base of the thumb to the base of the index finger has a , it is preferable that the anti-slip protrusion 2 is not provided.

Further, the anti-slip protrusion 2 is formed on the undercoat layer 11.
Although it is preferable to use a synthetic resin material that is compatible with the synthetic resin material of the surface layer 12, it may be formed of a material that is not compatible with the material of the anti-slip protrusion 2 and the base coating. layer 11,
The material of the skin layer 12 is not particularly limited.

Further, although the base coat layer 11 and the skin layer 12 are not necessarily necessary, by providing the base coat layer 11, the adhesion of the anti-slip protrusion 2 to the rod body 1 can be improved, and the connection can be made even stronger. There is also an advantage that by providing the skin layer 12, the wear resistance of the anti-slip protrusion 2 can be increased, and the durability can be increased.

In the above description, a rod body wrapped with narrow tape was used, but the structure of this rod body is not particularly limited.

(Effects of the Invention) As described above, the present invention uses a thick stencil with a thickness corresponding to the height of the protrusion having a non-slip height on the outer peripheral surface of the rod body 1, and silk screen prints the protrusion forming material. Since a large number of non-slip protrusions 2 were formed by printing, the non-slip protrusions 2 were
It is very easy to form, and costs can be reduced.Moreover, the anti-slip protrusion 2 can be formed only at the position where the anti-slip effect is highest in relation to the hand gripping the fishing rod, and the protrusion height of the anti-slip protrusion 2 can be can be set freely, which not only has a very high anti-slip effect, but also provides a comfortable grip.

Moreover, a pattern of a predetermined shape can be formed by the two groups of anti-slip protrusions, and the decorative value can be increased without forming a special pattern.

Furthermore, since the structure is such that the protrusion molding material adheres only to the printed area of the anti-coat protrusion 2, it is possible to prevent a decrease in the sensitivity of the hit that a fish feels when it bites the bait, and it has a high anti-slip effect. It can be made relatively lightweight.
