Description

The present invention relates to a fishing rod having a rod body to which mounting parts are attached.

A fishing rod in which mounting parts such as a fishing line guide and a reel seat are attached to a rod body is known. Conventionally, the mounting parts are mounted on the rod body by a thread or a resin sheet.

A fishing rod having an attachment component attached to a rod body by a thread is disclosed in, for example, Japanese Patent Application Laid-Open No. 2008-263841 (Patent Document 1) and Japanese Patent Application Laid-Open No. 2004-194563 (Patent Document 2).

In a conventional fishing rod having a mounting component attached to a rod body by a thread, there is a problem that the thread tends to loosen when a force is applied to the mounting component from the fishing line or the reel.

Fishing rods having mounting parts attached to the rod body by a resin sheet are, for example, Jikkenhei 2-26474 (Patent Document 3), International Publication No. 2018/042856 (Patent Document 4), and International Publication No. 2018. / 061345 (Patent Document 5). The resin sheet described in these patent documents is a prepreg sheet obtained by impregnating a matrix resin containing a thermosetting resin with reinforcing fibers.

Japanese Unexamined Patent Publication No. 2008-263841 Japanese Unexamined Patent Publication No. 2004-194563 Jitsukaihei No. 2-026444 International Publication No. 2018/042856 International Publication No. 2018/061345

Since the prepreg sheet is wound around the rod body so as to cover the mounting portion of the mounting component, a gap is created between the prepreg sheet and the mounting portion and the outer peripheral surface of the rod body. When the mounting component is attached to the rod body by the prepreg sheet, the fluidity of the heated matrix resin is increased, and the fluidized resin flows into the gap. Therefore, the matrix resin is likely to be lost in the region of the prepreg sheet facing the gap. When the matrix resin is cured in this state, visible pinholes and voids are generated in the region corresponding to the gap in the cured prepreg sheet. Since appearance quality is an important evaluation item for fishing rod products, it is desired to prevent or suppress the occurrence of appearance defects due to pinholes and voids.

The fluidized resin may not only flow inward of the rod (eg, towards the gaps described above), but may also flow back and forth along the outer surface of the rod to the front and back of the mounting component. The resin flow to the front and back of the mounting parts is also one of the causes of deterioration of appearance quality.

One of the objects of the present invention is to suppress deterioration of the appearance quality of a layer made of a prepreg sheet for fixing a mounting component to a rod body. Other objects of the invention will become apparent by reference to the entire specification.

The attached fishing line guide 10 is provided. In the illustrated embodiment, each of the reel seat 9 and the fishing line guide 10 corresponds to a mounting component attached to the outer peripheral surface of the rod body.

The rod body 2 is configured by connecting, for example, the original rod 3, the middle rod 5, the tip rod 7, and the like. Each of these rods is, for example, spliced in parallel. The original rod 3, the middle rod 5, and the tip rod 7 can be joined by a swing method, a reverse parallel connection method, an in-row method, or any other known joint method. The rod body 2 may be composed of a single rod body.

The original rod 3, the middle rod 5, and the tip rod 7 are made of, for example, a tubular body made of fiber reinforced resin. This fiber-reinforced resin tubular body is produced by winding a fiber-reinforced resin prepreg (prepreg sheet) in which reinforcing fibers are impregnated with a matrix resin around a core metal, and heating and curing the prepreg sheet. As the reinforcing fiber contained in this prepreg sheet, for example, carbon fiber, glass fiber, and any other known reinforcing fiber can be used. As the matrix resin contained in the prepreg sheet, a thermosetting resin such as an epoxy resin can be used. After the prepreg sheet is cured, the core metal is decentered. Further, the outer surface of the tubular body is appropriately polished. Each rod body may be configured in a solid state.

In the illustrated embodiment, the main rod 3, the middle rod 5, and the tip rod 7 are provided with a plurality of fishing line guides 10 (fishing line guides 10A to 10D) for guiding the fishing line to be unwound from the reel R mounted on the reel sheet 9. Has been done. More specifically, the original rod 3 is provided with one fishing line guide 10A, the middle rod 5 is provided with three fishing line guides 10B, and the tip rod 7 is provided with three fishing line guides 10C. A top guide 10D is provided at the tip of the tip rod 7. An arbitrary number of fishing line guides 10 are attached to the rod body 2. In the illustrated example, eight fishing line guides including the top guide 10D are attached to the rod body 2, but the number of fishing line guides attached to the rod body 2 may be nine or more, or seven. It may be as follows.

In the illustrated embodiment, the reel sheet 9 is attached to the outer peripheral surface of the original rod 3. The reel seat 9 is an arbitrary reel seat to which the reel R can be attached.

Next, with reference to FIGS. 2 and 3, a structure for attaching the fishing line guide 10B to the middle rod 5 and a method for attaching the fishing line guide 10B will be described. FIG. 2 is a perspective view for explaining a method of attaching the fishing line guide 10B to the middle rod 5, and FIG. 3 is a schematic cross-sectional view taken along the line I-I of FIG. When referring to the vertical direction and the horizontal direction of the rod body 5 and the fishing line guide 10B, the vertical direction and the horizontal direction of FIG. 3 are used as a reference.

As shown in these figures, the fishing line guide 10B has a foot 10a extending in the axial direction of the middle rod 5, and is attached to the outer peripheral surface of the middle rod 5 via the foot 10a. The foot 10a of the fishing line guide 10B is an example of a mounting portion of a mounting component. The foot 10a of the fishing line guide 10B has an upper surface 11a, a bottom surface 11b facing the upper surface 11a, and side surfaces 11c and 11d connecting the upper surface 11a and the bottom surface 11b in a cross-sectional view. The fishing line guide 10B is attached to the middle rod 5 so that the bottom surface 11b of the foot 10a is in contact with the outer peripheral surface of the middle rod 5. The bottom surface 11b of the foot 10a, in whole or in part, is in contact with the outer peripheral surface of the middle rod 5. In the illustrated embodiment, since the curvature of the bottom surface 11b is substantially the same as the curvature of the outer peripheral surface of the middle rod 5, almost all of the bottom surface 11b is in contact with the outer peripheral surface of the middle rod 5. When the curvature of the bottom surface 11b is different from the curvature of the outer peripheral surface of the middle rod 5, a part of the bottom surface 11b is in contact with the outer peripheral surface of the middle rod 5. Since the bottom surface 11b of the foot 10a is in contact with the outer peripheral surface of the middle rod 5, a filling member as described in, for example, Jikkendai 2-026474 is not provided between the foot 10a and the middle rod 5. However, if the curvature of the bottom surface 11b is different from the curvature of the outer peripheral surface of the middle rod 5, the resin may intervene between the bottom surface 11b and the outer peripheral surface of the middle rod 5 due to the resin flow from the prepreg sheet described later. be.

The foot 10a is cut out at a portion where the upper surface 11a and the side surface 11c are connected and at a portion where the upper surface 11a and the side surface 11c are connected. In the illustrated embodiment, a notch surface 11e and a notch surface 11f are formed at the left and right ends of the upper surface 11a of the foot 10a, respectively. The cutout surface 11e is a surface that connects the upper surface 11a and the side surface 11c. The cutout surface 11f is a surface that connects the upper surface 11a and the side surface 11d. The upper surface 11a is connected to the notch surface 11e at its left end E1 and is connected to the notch surface 11f at its right end E2. As shown in FIG. 3, the left end E1 of the upper surface 11a is located at one end of the upper surface 11a in the circumferential direction around the central axis A, and the right end E2 of the upper surface 11a is the other end of the upper surface 11a in the circumferential direction. Located on the edge of. The left end E1 of the upper surface 11a is an example of the first edge, and the right end E2 of the upper surface 11a is an example of the second edge. The side surface 11c is connected to the notch surface 11e at its upper end E3, and the side surface 11d is connected to the notch surface 11e at its upper end E4.

In one embodiment, at least one of the notch surface 11e and the notch surface 11f may be a part of the upper surface 11a. That is, the region including the notched surface 11e and the notched surface 11f may be referred to as the upper surface 11a. In this case, the upper end E3 of the side surface 11c coincides with the left end (first edge) of the upper surface 11a, and the upper end E4 of the side surface 11d coincides with the right end (second edge) of the upper surface 11a.

A first fiber reinforced resin layer 20, a second fiber reinforced resin layer 30, and a coating layer 40 are provided on the outside of the foot 10a of the fishing line guide 10B. The terms "outside" and "inside" as used herein mean "outside" and "inside" in the radial direction of the center rod 5, unless the context requires different meanings.

The first fiber reinforced resin layer 20 is provided around the middle rod 5 so as to cover the foot 10a. In one embodiment, the number of turns of the first fiber reinforced resin layer 20 is set to 1 ply or more for reliable fixing of the fishing line guide 10B, and less than 2 plies for weight reduction. The second fiber reinforced resin layer 30 is provided on the outside of the first fiber reinforced resin layer 20. In one embodiment, the number of turns of the second fiber reinforced resin layer 30 is 1 ply or more and less than 2 plies.

In one embodiment, one end 20a of the first fiber reinforced resin layer 20 is a fishing line guide 10B (for example, a foot 10a of the fishing line guide 10B) in the circumferential direction around the central axis A, as shown in FIG. It is provided so as to be located at a position of 90 ° or more and less than 180 ° counterclockwise from the center portion 11g) which is the center in the circumferential direction. In the illustrated embodiment, one end 20a of the first fiber reinforced resin layer 20 is located at a position of 90 ° + θ1a (0 ≦ θ1a <90 °) counterclockwise in the circumferential direction from the center portion 11g.

In one embodiment, the other end 20b of the first fiber reinforced resin layer 20 is on the opposite side of one end 20a with respect to the center portion 11g of the fishing line guide 10B in the circumferential direction around the central axis A. In one embodiment, the other end 20b of the first fiber reinforced resin layer 20 is located at a position of 90 ° or more and less than 180 ° clockwise from the center portion 11g of the fishing line guide 10B. In the illustrated embodiment, the other end 20b of the first fiber reinforced resin layer 20 is located at a position of 90 ° + θ1b (0 ≦ θ1b <90 °) clockwise from the center portion 11g in the circumferential direction. θ1b may have the same angle as θ1a or may have a different angle. In the illustrated embodiment, since θ1a = θ1b, the other end 20b of the first fiber reinforced resin layer 20 has one end with respect to the center portion 11g of the fishing line guide 10B in the circumferential direction around the central axis A. It is in a position symmetrical to 20a. By arranging the one end 20a and the other end 20b of the first fiber reinforced resin layer 20 in the circumferential direction around the central axis A at a target position with respect to the center portion 11g of the fishing line guide 10B in this way, the middle portion is formed. It is possible to prevent the center of gravity of the rod 5 from being biased to the left or right with respect to the central axis A.

As described above, the position of one end 20a of the first fiber reinforced resin layer 20 is 90 ° + θ1a counterclockwise from the center portion 11g of the fishing thread guide 10B, and the position of the other end 20b is clockwise from the center portion 11g. By setting the position to 90 ° + θ1b, the number of turns of the first fiber reinforced resin layer 20 can be 1.5 plies or more and less than 2.0 plies.

When the fishing rod 1 is used, a force in the direction of swinging the fishing line guide 10B around the central axis A of the rod body acts on the fishing line guide 10B from the fishing line. Due to this force, the left end and the right end of the bottom surface 11b of the foot 10a tend to rise from the outer peripheral surface of the middle rod 5. The position of one end 20a of the first fiber reinforced resin layer 20 is 90 ° + θ1a counterclockwise from the center portion 11g of the fishing line guide 10B, and the position of the other end 20b is 90 ° + θ1b clockwise from the center portion 11g. By setting the position, when the foot 10a is about to be lifted by the force from the fishing line, the portion near one end 20a and the portion near the other end 20b of the first fiber reinforced resin layer 20 become hooks, and the foot 10a becomes a hook. It is possible to suppress the floating of the left end and the right end of the.

In one embodiment, one end 30a of the second fiber reinforced resin layer 30 is located at a position of 90 ° + θ1a (0 ≦ θ1a <90 °) counterclockwise from the center portion 11g, and the other end 30b is the center. It is provided on the outside of the first fiber reinforced resin layer 20 so as to be located at a position of 90 ° + θ1b clockwise from the portion 11g. As described above, in the illustrated embodiment, one end 20a of the first fiber reinforced resin layer 20 is in the same position in the circumferential direction as the one end 30a of the second fiber reinforced resin layer 30 in the circumferential direction around the central axis A. However, the circumferential position of one end 20a of the first fiber reinforced resin layer 20 and the circumferential position of one end 30a of the second fiber reinforced resin layer 30 may be different from each other. Similarly, in the illustrated embodiment, the other end 20b of the first fiber reinforced resin layer 20 is at the same position as the other end 30b of the second fiber reinforced resin layer 30, but the other end of the first fiber reinforced resin layer 20. The circumferential position of 20b and the circumferential position of the other end 30b of the second fiber reinforced resin layer 30 may be different from each other.

As described above, the fishing line guide 10B is attached to the outer peripheral surface of the middle rod 5 by the first fiber reinforced resin layer 20 and the second fiber reinforced resin layer 30 via the foot 10a. In FIG. 3, for the sake of visibility of each member, between the first fiber reinforced resin layer 20 and the outer surface of the middle rod 5, and the first fiber reinforced resin layer 20 and the second fiber reinforced resin layer 30. Each member is drawn so that there is a gap between the two, but in reality, the first fiber reinforced resin layer 20 is in close contact with the outer surface of the inner rod 5, and the first fiber reinforced resin layer 20 is in close contact with the outer surface. And the second fiber reinforced resin layer 30 are also in close contact with each other.

The material of the coating layer 40 is not limited to those exemplified in the present specification, and various resins can be used as the material. The coating layer 40 may be transparent or well colored.

As shown in FIG. 3, the gap G1 is defined by the side surface 11c of the foot 10a, the outer peripheral surface of the middle rod 5, and the inner peripheral surface of the first fiber reinforced resin layer 20. Further, the gap G2 is defined by the side surface 11d of the foot 10a, the outer peripheral surface of the middle rod 5, and the inner peripheral surface of the first fiber reinforced resin layer 20. When the first sheet 20s, which will be described later, is heated, the matrix resin contained in the first sheet 20s flows and flows into the gap G1 and the gap G2. Therefore, at least a part of the gap G1 and the gap G2 is filled with the resin 21 derived from the matrix resin contained in the first sheet 20s.

Subsequently, an example of a method of attaching the fishing line guide B10 to the middle rod 5 will be described. When attaching the fishing line guide B10 to the middle rod 5, first, the rod body 5, the fishing line guide 10B, the first sheet 20s, and the second sheet 30s are prepared.

As described above, the rod body 5 is created by heating and curing the prepreg sheet wound around the core metal.

Any fixed guide can be used as the fishing line guide 10B. The fishing line guide 10B may be a single foot type shown in the figure or a double foot type.

The first sheet 20s is a prepreg sheet in which reinforcing fibers are impregnated with a matrix resin. The reinforcing fiber contained in the first sheet 20s is an example of the first reinforcing fiber, and the matrix resin contained in the first sheet 20s is an example of the first matrix resin.

The reinforcing fiber contained in the first sheet 20s is an organic fiber. The organic fiber is, for example, one or more fibers selected from the group consisting of polyolefins, polyamides, polyacrylonitrile, and polyesters. The matrix resin is, for example, a thermosetting resin. Thermosetting resin refers to a resin that irreversibly cures due to a chemical reaction when heated. Examples of the thermosetting resin that can be used as the matrix resin for the first sheet 20s include urea resin, melamine resin, phenol resin, epoxy resin, unsaturated polyester resin, alkyd resin, and urethane resin. The thickness of the first sheet 20s is, for example, 20 μm to 300 μm. As the first sheet 20s, an appropriate commercially available product can be used.

In one embodiment, the matrix resin contained in the second sheet 30s is more easily wetted with the reinforcing fibers of the first sheet 20s than the reinforcing fibers of the second sheet 30s. In other words, the wettability of the reinforcing fibers contained in the first sheet 20s and the matrix resin contained in the second sheet 30s is the wetting property of the reinforcing fibers contained in the second sheet 30s and the matrix resin contained in the second sheet 30s. Higher than sex. When the matrix resin of the second sheet 30s is an epoxy resin, one or more organic fibers selected from the group consisting of polyolefin, polyamide, polyacrylonitrile, and polyester are used as the reinforcing fibers of the first sheet 20s, and the second sheet is used. By using carbon fiber or glass fiber as the reinforcing fiber of the sheet 30s, the wettability between the organic fiber contained in the first sheet 20s and the epoxy resin can be improved with the carbon fiber or glass fiber contained in the second sheet 30s and the epoxy resin. It is higher than the wettability of.

In one embodiment of the present invention, the matrix resin of the first sheet 20s may have a higher curing temperature than the matrix resin of the second sheet 30s. For example, when an 80 ° C. curable type epoxy resin is used as the matrix resin of the second sheet 30s, a 120 ° C. curable type epoxy resin can be used as the matrix resin of the first sheet 20s. The thickness of the second sheet 30s may be, for example, 20 μm to 300 μm. As the second sheet 30s, an appropriate commercially available product can be used.

The resin content of the matrix resin contained in the second sheet 30s is, for example, 20 wt% to 50 wt% or 30 when the total of the mass of the reinforcing fibers and the mass of the matrix resin in the second sheet 30s is 100 wt%. It is said to be mass% to 40% by mass.

The reinforcing fibers contained in the second sheet 30s may be aligned in a direction forming a predetermined angle with respect to the axial direction along the central axis A of the rod body 2. For example, the reinforcing fibers contained in the second sheet 30s may be aligned at an inclination of 45 ° with respect to the axial direction along the central axis A of the rod body 2. The reinforcing fibers contained in the second sheet 30s may be knitted in a plain weave shape. The reinforcing fiber contained in the 2 sheets 30s may be a non-woven fabric.

The matrix resin contained in the first sheet 20s or the second sheet 30s is a composition containing a thermosetting resin as a main component. This resin composition may contain known additives. When the resin composition contains a thermosetting resin and an additive, the ratio of the mass of the thermosetting resin to the total mass is, for example, 50, when the total mass of the resin composition is 100%. % Or more, 60% or more, 70% or more, 80% or more, or 90% or more.

In order to attach the fishing line guide 10B to the rod body 5, as shown in FIG. 2, the foot 10a of the fishing line guide 10B is placed on the outer peripheral surface of the middle rod 5. Next, one end of the first sheet 20s is placed on the outer peripheral surface of the middle rod 5, and the first sheet 20s is wound by a predetermined number of plies so as to surround the outer peripheral surface of the middle rod 5. In one embodiment, as shown in FIG. 3, the first sheet 20s is started from the position of 90 ° + θ1a counterclockwise from the center portion 11g, and 90 ° + θ1b clockwise from the center portion 11g. The winding is finished at the position of. The positions of the winding start and winding end are adjusted as appropriate. As a result, the foot 10a is covered with the first sheet 20s together with the rod body 5. When the first sheet 20s is wound around the middle rod 5, a gap corresponding to the gap G1 is formed on the left side of the foot 10a, and a gap corresponding to the gap G2 is generated on the right side of the foot 10a.

Next, the second sheet 30s is wound around the outside of the first sheet 20s wound around the rod body 5 to obtain a wound body.

Next, by heating the wound body in which the first sheet 20s and the second sheet 30s are wound around the rod body 5, the matrix resin contained in the first sheet 20s flows and then cures. The first fiber reinforced resin layer 20 is formed, the matrix resin contained in the second sheet 30s flows, and then the matrix resin is cured to form the second fiber reinforced resin layer 30. The fishing line guide 10B is fixed to the rod body 5 by the first fiber reinforced resin layer 20 and the second fiber reinforced resin layer 30.

The winding body is taken out of the heating furnace after heating for a predetermined time and cooled at room temperature for a predetermined time. After the winding body is sufficiently cooled, a coating layer for improving weather resistance or decorativeness is formed so as to cover the second fiber reinforced resin layer 30 formed on the winding body. May be done.

The winding body can be heated by using a known heating furnace. For example, by putting the winding body in a heating furnace kept at a predetermined temperature for a predetermined time, the heating required for curing the matrix resin contained in the first sheet 20s and the second sheet 30s is performed. The temperature of the heating furnace is, for example, 70 to 170 ° C., 80 to 160 ° C., 85 to 150 ° C., or 90 to 120 ° C., but heating is performed at a temperature other than these depending on the curing temperature of the matrix resin. May be good. The heating time of the winding body in the heating furnace is, for example, 5 minutes to 3 hours, 15 minutes to 2.5 hours, or 30 minutes to 2 hours, but the winding body is heated only for other heating times. You may. When the winding body is heated, a tightening tape may be wound around the winding body so that the first sheet 20s and the second sheet 30s wound around the middle rod 5 do not move during heating.

When the curing temperature of the matrix resin contained in the first sheet 30s is lower than the curing temperature of the matrix resin contained in the second sheet 30s, the inner matrix resin of the first sheet 20s is cured first, and then the curing temperature. The higher outer matrix resin of the second sheet 30s is cured.

When the winding body is heated, the matrix resin contained in the first sheet 20s flows and flows into the gap G1 and the gap G2. As a result, at least a part of the gap G1 and the gap G2 is filled with the resin 21 flowing from the first sheet 20s. The resin 21 that fills the gap G1 and the gap G2 allows the fishing line guide 10B to be more firmly attached to the middle rod 5.

As the matrix resin flows from the first sheet 20s into the gap G1 and the gap G2, it faces a part of the region of the first sheet 20s (particularly, the region facing the gap G1 and the gap G2 in the circumferential direction around the central axis A). The matrix resin is reduced or depleted in the region). Since the second sheet 30s is provided on the outside of the first sheet 20s, the matrix resin of the second sheet 30s flows into the region where the matrix resin is lost in the first sheet 20s. In the above embodiment, the wetting property of the reinforcing fiber contained in the first sheet 20s and the matrix resin contained in the second sheet 30s is the wetting property of the reinforcing fiber contained in the second sheet 30s and the matrix contained in the second sheet 30s. Since the wettability with the resin is higher, the matrix resin of the second sheet 30s tends to wet and spread along the reinforcing fibers of the first sheet 20s. Therefore, when there is a region where the matrix resin is insufficient in the first sheet 20s, the matrix resin of the second sheet 30s whose fluidity has been increased by heating is in the direction of protruding to the outside of the second sheet 30s. It becomes easy to flow into the inside of the first sheet 20s. As a result, at least a part of the voids in the first sheet 20s generated by the flow of the matrix resin into the gap G1 and the gap G2 is filled with the matrix resin flowing from the second sheet 30s. As a result, it is possible to prevent the matrix resin of the second sheet 30s from sticking out to the front and back of the foot 10a of the fishing line guide 10B during heating, and it is possible to suppress the generation of pinholes and voids that cause deterioration of the appearance quality. can.

When the curing temperature of the matrix resin of the first sheet 20s is higher than the curing temperature of the second sheet 30s, the matrix resin of the first sheet 20s is in a fluid state when the matrix resin of the second sheet 30s melts and flows. It doesn't become. Therefore, the matrix resin of the second sheet 30s does not flow into the gap G1 and the gap G2, and the curing reaction proceeds. Subsequently, the matrix resin of the first sheet 20s having a high curing temperature is melted, and the melted resin flows into the gap G1 and the gap G2. As described above, when the curing temperature of the matrix resin of the first sheet 20s is higher than the curing temperature of the second sheet 30s, the first sheet having a higher curing temperature when the matrix resin of the second sheet 30s flows. The 20S matrix resin does not flow. As a result, the matrix resin of the second sheet 30s is less likely to flow into the voids of the first sheet 20s, so that deterioration of the appearance quality can be suppressed.

In one embodiment, as shown in FIG. 3, the first fiber reinforced resin layer 20 is the thickness of two layers of the first sheet 20s in the region facing the gap G1 and the gap G2 in the circumferential direction. have. Similarly, the second fiber reinforced resin layer 30 has the thickness of two layers of the second sheet 30s in the region facing the gap G1 and the gap G2 in the circumferential direction. Thereby, the generation of pinholes and voids due to the matrix resin flowing into the gap G1 and the gap G2 from the first sheet 20s can be further suppressed.
