Description

Technical Field

[0001] The present invention relates to a handle component for a fishing rod having a reel seat and a fishing rod having the handle component. Background Technology

[0002] Previously, various types of fishing rods with reel seats and handles were known.

[0003] On such a fishing rod, a rod reel holder and a rod handle are typically mounted on the rod body, and a reel foot mounting part is formed on the rod reel holder for mounting the reel foot on the upper or lower side of the rod body.

[0004] As such a fishing rod, for example, Patent Document 1 discloses a fishing rod comprising: a rod body; a cylindrical reinforcing resin layer disposed on the circumferential surface of the rod body, having an uneven surface formed on the outer circumference; and a reel seat, which is injection molded on the outer circumferential surface of the reinforcing resin layer.

[0005] Furthermore, Patent Document 2 discloses a fishing rod with a rear handle portion on the rear side of the reel seat. The reel seat has a cylindrical reel seat body with a reel foot holding portion for holding the reel. The fishing rod has: a rod body; and a rear handle rod body. When the hollow rod body is formed from pre-impregnated film, the rear diameter is made larger by a diameter change rate greater than that of the rod body, and the rear handle portion is integrally formed. Furthermore, by forming an overlap portion of a predetermined length between the rear portion of the rod body and the front portion of the rear handle rod body, the two parts overlap and are joined together as one, and at least a portion of the overlap portion is located inside the reel seat body.

[0006] Patent documents

[0007] Patent Document 1: Japanese Patent Application Publication No. 11-137132

[0008] Patent Document 2: Japanese Patent Application Publication No. 2013-21923 Summary of the Invention

[0009] However, the fishing rod disclosed in Patent Document 1 has the following problem: because a solid reel seat is provided on the cylindrical reinforcing resin layer on the rod body, which is injection molded on the outer peripheral surface of the reinforcing resin layer, the weight is increased. Furthermore, not only does the thick wall of the reel seat cause it to function as a cushioning material, resulting in a significant decrease in the sensitivity of the fishing rod, but it also does not take any consideration for the grip.

[0010] Furthermore, even the fishing rod disclosed in Patent Document 2 has the following problem: since the rear grip rod body and the reel seat body are joined to the rod body, it inevitably leads to an increase in the weight used for bonding. Moreover, not only do the bonded parts and multiple layers cause them to function as cushioning materials, resulting in a significant decrease in the sensitivity of the fishing rod, but also no consideration is given to the grip.

[0011] The present invention was made in view of the above circumstances, and the technical problem to be solved is to provide a fishing rod handle component that is not only lightweight and does not easily attenuate vibrations from the rod body, but also has a fishing rod handle component that greatly improves grip. Other than the above-described objectives of the present invention will be apparent from the entire description.

[0012] One embodiment of the present invention relates to a fishing rod handle component that integrally forms a raised portion, a reel seat body, and a grip. The reel seat body has a reel foot mounting portion for mounting the reel foot. The grip is positioned behind the reel seat body when viewed axially. The fishing rod handle component is made of carbon fiber reinforced plastic. The characteristic feature is that, when viewed axially, the reel seat body has a front grip portion extending from 40 mm in front of the raised portion to 100 mm behind it. A pair of first portions are formed in the upper half of the front grip portion in a manner that clamps a convex curved surface and is circumferentially separated from each other. The pair of first portions occupy at least 10° of circumferential angle when viewed. The first portions are either flat or curved. When the first portions are curved, the radius of curvature observed circumferentially on the reel seat body is larger than the radius of curvature of the second portion constituting the lower half of the front grip portion.

[0013] In one embodiment of the present invention, the handle component for a fishing rod is configured such that the radius of curvature of the curved surface of the first portion is R20 or more or -R30 or less. Furthermore, in another embodiment of the present invention, the handle component for a fishing rod is configured such that the radius of curvature of the curved surface of the second portion is R13 or more and less than R20.

[0014] One embodiment of the present invention relates to a fishing rod handle component comprising a transition portion between the first portion and the second portion, the transition portion being a bend or a bend surface. Furthermore, in one embodiment of the fishing rod handle component according to the present invention, when the transition portion is a bend surface, its radius of curvature ranges from R0.1 to R1.0.

[0015] In a fishing rod handle component according to one embodiment of the present invention, the handle, when viewed in the axial direction, has a rear grip portion within a range of 100 mm from the rear end. A third portion is formed in the upper half of the rear grip portion, which occupies at least 10° when viewed in the circumferential direction. The third portion is either flat or curved. When the third portion is curved, the radius of curvature observed in the circumferential direction of the handle is larger than the radius of curvature of the fourth portion constituting the lower half of the rear grip portion.

[0016] In one embodiment of the present invention, the handle component for a fishing rod is formed to be hollow.

[0017] One embodiment of the present invention relates to a handle component for a fishing rod in which the end of the fishing rod body is mounted on one end of the reel seat body, i.e., the end opposite to the grip.

[0018] In one embodiment of the present invention, the carbon fiber of the carbon fiber reinforced plastic of the fishing rod handle component is continuously formed along the length direction of the fishing rod handle component.

[0019] One embodiment of the present invention relates to a fishing rod configured to include any of the above-described fishing rod handle components and rod body.

[0020] According to the above embodiments, a fishing rod handle component that is not only lightweight and does not easily attenuate vibrations from the rod body, but also has a fishing rod reel seat that greatly improves grip, and a fishing rod having the fishing rod handle component can be provided.

Detailed Implementation

[0032] The embodiments of the fishing rod according to the present invention will now be described in detail with reference to the accompanying drawings. In the multiple drawings, common constituent elements are labeled with the same reference numerals in all drawings. For ease of explanation, the drawings are not necessarily drawn to an exact scale; this should be noted.

[0033] Figure 1 This figure illustrates one embodiment of the fishing rod according to the present invention. As shown, a fishing rod 1 according to one embodiment of the present invention includes: a rod body 2; a reel R, which is mounted on the rod body 2 via a reel seat 9; and a fishing line guide 10, which is mounted on the rod body 2. In the illustrated embodiment, the reel seat 9 and the fishing line guide 10 correspond to mounting parts respectively mounted on the outer peripheral surface of the rod body.

[0034] The rod body 2 is constructed, for example, by connecting the first section 3, the middle section 5, and the tip section 7. These rod bodies are joined, for example, by a plug-in joint. The first section 3, the middle section 5, and the tip section 7 can be joined by a pull-out method, a reverse plug-in method, a sleeve method, or any other known joining method. The rod body 2 can also be constructed from a single rod body.

[0035] The first section 3, the middle section 5, and the tip section 7 are, for example, tubular bodies made of fiber-reinforced resin. These tubular bodies are manufactured by winding a fiber-reinforced resin polyester film (prepreg) impregnated with a matrix resin in reinforcing fibers onto a mandrel, and then heating and curing the prepreg. The reinforcing fibers included in the prepreg can be, for example, carbon fiber, glass fiber, or any other known reinforcing fibers. The matrix resin included in the prepreg can be a thermosetting resin such as epoxy resin. After the prepreg is cured, the mandrel is removed. Furthermore, the outer surface of the tubular body is appropriately ground. Each rod can also be constructed as a solid shape.

[0036] In the illustrated embodiment, multiple line guides 10 (line guides 10A to 10D) are provided on the first section 3, the middle section 5, and the tip section 7 to guide the fishing line released from the reel 6 mounted on the fishing rod reel holder 9. More specifically, line guide 10A is provided on the first section 3, line guide 10B is provided on the middle section 5, and line guide 10C is provided on the tip section 7. Although a top guide 10D is provided at the top of the tip section 7, detailed description is omitted.

[0037] Next, refer to Figure 2 The basic structure of the reel holder body 12 and the reel holder 9 will be described. The reel holder body 12 includes a reel foot holding portion 12a along its axial direction, which holds the reel foot 6a of the fishing reel 6. The reel holder body 12 is generally formed into a cylindrical shape. The reel holder body 12 may be configured to have a length in the range of 300 mm to 450 mm, for example, but is not limited to this.

[0038] Furthermore, the reel holder body 12 has a raised portion (trigger) 12b formed on the opposite side of the reel foot placement portion 12a. The raised portion (trigger) 12b has an outer curved shape that facilitates gripping by supporting the thumb pad or its proximal portion when held by the hand.

[0039] The cable reel holder body 12's cable reel foot mounting portion 12a is formed to be flat, or formed to have a greater curvature and be substantially flat than other circumferential portions (e.g., raised portions 12b) adjacent to the cable reel foot mounting portion 12a of the cable reel holder body 12, and is formed to be Figure 2The diagram shows the axial extension of the reel holder body 12. A retaining cover 14 is integrally mounted on one end (the rod end side) of the reel holder body 12. One end of the reel foot mounting portion 12a of the reel holder body 12 is disposed inside the retaining cover 14.

[0040] On the other end (rod top side) of the reel holder body 12, a movable cover 22 is axially movable. The reel holder body 12 and the movable cover 22 are collectively referred to as the reel holder 9, but detailed descriptions are omitted.

[0041] Next, refer to Figure 3 (and Figure 2 The following describes a fishing rod handle component 20 according to one embodiment of the present invention. Here, although the fishing rod handle component 20 is composed of the reel seat body 12 described above and a grip 4 formed adjacent to the reel seat body 12, a connecting member may be provided therebetween if necessary. Furthermore, although the reel seat 9 and the grip 4 described above may be collectively referred to as the fishing rod handle component 20, it will be described as described above in this embodiment.

[0042] As shown in the figure, in one embodiment of the present invention, the fishing rod handle component 20 is integrally formed by a reel seat body 12 having a reel foot mounting portion 12a with a reel foot 6b and a handle 4 connected to the reel seat body 12. This fishing rod handle component is made of carbon fiber reinforced plastic. Furthermore, as described later... Figure 4 As shown in (b), the handle component 20 for a fishing rod according to one embodiment of the present invention can be formed as a hollow part. In this way, the weight can be significantly reduced without affecting the sensitivity imparted to the fishing rod.

[0043] Next, refer to Figure 4(a) and (b) describe a fishing rod handle component 20 according to one embodiment of the present invention. As shown in the figure, the fishing rod handle component 20 according to one embodiment of the present invention is constructed by integrally forming a reel seat body 12 having a reel foot mounting portion 12a having a reel foot 6b and a handle 4 connected to the reel seat body 12. The fishing rod handle component 20 is made of carbon fiber reinforced plastic. When viewed in the axial direction of the reel seat body 12, a grip portion 21 is provided in the range from 40 mm in front of the raised portion (trigger) 12b to 100 mm (X) behind it. The first part 23 of the upper half of the grip portion 21, which occupies at least 10° when viewed in the circumferential direction, is configured to be a curved surface with a larger radius of curvature than the radius of curvature of other parts 24 when viewed in a plane (in the illustrated example, the first part 23 is a plane) or in the circumferential direction of the reel seat body. Here, the front of the raised part (trigger) 12b refers to the direction of the side where the rod body is installed, and the rear of the raised part (trigger) 12b refers to the direction of the side of the grip 4.

[0044] According to one embodiment of the present invention, the handle component 20 for a fishing rod achieves significant weight reduction by integrally molding the handle component. Furthermore, since integral molding reduces the attenuation of vibrations from the rod body, it not only improves the sensitivity of the fishing rod but also significantly enhances the grip when holding the reel seat. Thus, because a surface is provided, which is a straight or nearly straight curved surface forming the part contacted by the fingertips when holding the handle, it functions to prevent rotation relative to the direction of rotation centered on the axis of the handle, thus significantly improving grip. Here, when holding the fishing rod, considering the hypothetical outer diameter of the handle (e.g., φ20–27 mm, but not limited thereto) and the width of the angler's fingers (10–19 mm), and considering the proportions required for the fingers to achieve the anti-rotation effect, it is preferable that the upper half of the handle 21, when viewed from a circumferential angle, is at least 10° or more. Furthermore, it is preferable if the central part of the grip that the fingers touch (when viewed along the axial direction of the grip, the central part that the fingers touch, for example, the part from 30 mm in front of the raised part 12b to 80 mm behind) is measured at an angle of 30° or more.

[0045] According to one embodiment of the present invention, the handle component 20 for a fishing rod is configured such that the first part 23 of the upper half of the grip portion 21, when viewed from a circumferential angle, occupies at least 10° of angle (in... Figure 4 In the example shown in (b), the radius of curvature of the surfaces forming a pair (2) of the first part 23) is greater than R20 or less than -R30. Furthermore, the first part 23 can be as follows: Figure 4 (b) Two parts are provided, but one or more parts can also be provided (this applies to the entire specification). Thus, since the transition between the first and second parts, from the fingertip to near the first joint, provides an anti-rotation effect when holding the fishing rod handle, grip can be significantly improved. Furthermore, in one embodiment of the present invention, the fishing rod handle component is configured such that the other parts 24 ( Figure 4 The radius of curvature of the lower half shown in (b) is greater than R13 and less than R20.

[0046] One embodiment of the fishing rod handle component according to the present invention is configured such that a transition portion is provided between a first portion of the upper half of the grip and the other second portion. Furthermore, in one embodiment of the fishing rod handle component according to the present invention, the transition portion is a bend (a bend point in cross-section (not shown)) or a bend surface (a straight line or curve in cross-section, described later). Figure 5 In the example shown, the curve of the bend surface 25 is used. When this bend surface is used, the plane or radius of curvature is in the range of R0.1 to R1.0. In this way, since the transition part acts to sink into the knuckle (fusion), the anti-rotation effect can be fully utilized, thus greatly improving the grip.

[0047] In a fishing rod handle component according to one embodiment of the present invention, when viewed in its axial direction, the handle has a grip portion within a range of 100 mm (Y) from the rear end, and the first part of the upper half of the grip portion, which occupies at least 10° when viewed in a circumferential angle, is configured as a curved surface with a larger radius of curvature than the second part when viewed in a plane or in the circumferential direction of the handle.

[0048] According to one embodiment of the present invention, the handle component 20 for a fishing rod achieves significant weight reduction by integrally molding the handle component. Furthermore, since integral molding reduces the attenuation of vibrations from the rod body, it not only improves the sensitivity of the fishing rod but also significantly enhances the grip when holding the handle. Thus, because a surface is provided, which is a straight or nearly straight curved surface forming the part contacted by the fingertips when holding the handle, it can prevent rotation relative to the direction of rotation centered on the handle's axis, thus significantly improving grip. Here, it is considered that when holding the fishing rod, considering the hypothetical outer diameter of the handle (e.g., φ20–27 mm, but not limited thereto) and the width of the angler's fingers (10–19 mm), and considering the proportions required for the fingers to achieve the anti-rotation effect, the upper half of the grip portion 21 is preferably viewed at an angle of at least 10° or more in the circumferential direction. Furthermore, it is considered better if the part of the grip that the fingers touch (observed axially, for example, the part of the grip from 0mm to 80mm from the rear end) is measured at an angle of 30° or more.

[0049] One embodiment of the present invention relates to a fishing rod configured to include a handle component and a rod body, as described in one embodiment of the present invention.

[0050] According to one embodiment of the present invention, a fishing rod can achieve significant weight reduction by integrally molding the handle component. Furthermore, since integral molding reduces the attenuation of vibrations from the rod body, not only is the sensitivity of the fishing rod improved, but the grip can also be significantly improved by forming a holding portion. Thus, because a surface is provided, which is a straight or nearly straight curved surface forming the part that the fingertips contact when gripping the handle, it can function as an anti-rotation mechanism relative to the direction of rotation with the handle axis as the center of rotation, thereby significantly improving grip.

[0051] Next, refer to Figure 5-7 Using its sectional view ( Figure 4 (a) Section AA shows the gripping portion 21 of a fishing rod handle member 20 according to an embodiment of the present invention (the hollow portion is omitted for ease of explanation). Although the same applies to the gripping portion of the handle 4, the gripping portion 21 of the reel seat body 12 will be used as an example for the following description. Here, the position of the first portion in the axial direction of the fishing rod handle member 20 according to an embodiment of the present invention is not limited to... Figure 4The position of section AA in (a) can also be the position described above. Furthermore, in one embodiment of the present invention, the circumferential position of the first part (its cross-section) on the handle member 20 of the fishing rod can be the same as the axial position of the gripping part 21, or it can be different depending on its position.

[0052] first, Figure 5 (a) shows an example of a cross-sectional view of the grip portion 21 of the handle component 20 for fishing rods. Figure 5 (b) shows its enlarged view. As shown, in a fishing rod handle component 20 according to one embodiment of the present invention, the first part 23 of the upper half of the grip portion 21, which occupies at least 10° of angle when viewed in the circumferential direction at an angle (α), is shown. Figure 5 In the example shown in (a), a pair (2) of the first part 23) are formed, which are configured to be in a plane (in Figure 5 In example (a), the first part 23 is a plane, or, when viewed circumferentially from the reel seat body, a surface with a larger radius of curvature than the other parts 24. Furthermore, in one embodiment of the invention, the circumferential angle (the amount of angle occupied in the upper half) of the first part on the fishing rod handle member 20 can be the same regardless of the axial position of the grip 21, or it can vary depending on its position. As described above, when holding the fishing rod, taking into account the hypothetical outer diameter of the handle (e.g., φ20~27mm, but not limited thereto) and the width of the angler's fingers (10~19mm), and considering the proportion required for the fingers to exert an anti-rotation effect, it is preferable that the upper half of the grip 21 is at least 10° when viewed from a circumferential angle, and that the central part of the grip that the fingers touch (when viewed from the axial direction of the grip, the central part that the fingers touch, for example, the part from 30mm in front of the raised portion 12b to 80mm behind) is at least 30°.

[0053] Figure 5 (b) shows that Figure 5 (a) plane ( Figure 5 (b) shows three curves: A) with a radius of curvature of R20, B) with a radius of curvature of -R30. It is hoped that the term "larger radius of curvature" will be understood as referring to a larger absolute value.

[0054] also, Figure 5 (b) shows the first part 23 as an example, the upper half of the gripping part 21, when viewed at a circumferential angle, occupies at least 10° of the first part 23 (in Figure 5In the example shown in (a), the radius of curvature of the surfaces forming a pair (2) of the first part 23 can be configured to be R20 or more or -R30 or less. Furthermore, the first part 23 of the gripping portion 21 can be formed at an angle ranging from 5 degrees to 45 degrees in the circumferential direction of the upper half (in... Figure 5 In the example shown in (a), the angle is within 40° (angle α). This angle can be varied depending on the number of first portions 23 provided on the grip 21. Furthermore, between the first portion 23 and the second portion 24, a bend line (an inflection point in cross-section) or a bend surface (a plane (a straight line in cross-section) or a curved surface (a curve in cross-section)) is formed, with the radius of curvature of the bend surface ranging from R0.1 to R1.0. Figure 5 In the examples shown in (a) and (b), a bend surface 25 is formed, the radius of curvature of which is in the range of R0.1 to R1.0. In this way, a circle is formed instead of an edge, so as not to hurt the hand when gripping. In addition, it can also serve to allow the bend surface 25 to sink into and fuse with the knuckle.

[0055] Here, the upper part refers to Figure 5 (a) shows angles ranging from 0° to 180°. Furthermore, the lower half refers to... Figure 5 (a) shows an angle ranging from 180° to 360°. Other parts (part 2) 24 refer to the portion other than part 1, but for convenience in this specification, it refers to the lower half. Furthermore, the angle range provided with part 1 23 can vary or remain the same depending on the axial position of the handle component 20 for the fishing rod. This also applies throughout this specification.

[0056] Next, Figure 6 Another example is shown: a cross-sectional view of the grip portion 21 of the handle component 20 for a fishing rod. As shown, the first portion 23 of the grip portion 21 can be formed at an angle ranging from 45 degrees to 90 degrees circumferentially in the upper half (in... Figure 6 In the example shown, the angle is 40° (angle β). In the illustrated example, part 23 is formed as a plane.

[0057] Next, Figure 7 Other examples are shown in cross-sectional view of the grip portion 21 of the handle component 20 for fishing rods. As shown, the first portion 23 of the grip portion 21 can be formed at an angle ranging from 5 to 60 degrees circumferentially in the upper half (in... Figure 7 In the example shown, the angle is 55° (angle γ). In the illustrated example, the first part 23 is formed as a surface with a radius of curvature greater than R20 or less than -R30.

[0058] Next, Figure 9Other examples showing a cross-sectional view of the grip portion 21 of the handle component 20 for fishing rods. For example... Figure 9 As shown in (a) and (b), the first part 23 of the gripping part 21 is composed of part 23a and part 23b, with part 23a formed at an angle ranging from 5 to 45 degrees in the circumferential direction of the upper half (in Figure 9 In the example shown, within a 40° angle (angle α), part 23b is formed at an angle ranging from 45 to 90 degrees in the circumferential direction of the upper half (in Figure 9 In the example shown, within a 40° angle (angle β) (in the illustrated example, a pair of 23a and 23b are formed on the left and right sides (i.e., a total of 4 parts)). Thus, the first part 23 of the gripping part 21 is provided with two parts, and when a pair is formed, there are a total of 4. This further improves the anti-rotation effect during gripping. Here, the first part 23 of the gripping part 21 is not limited to a specific shape and can be conceived in various forms. Furthermore, in... Figure 9 In (b), a transition section is formed between parts 23a and 23b, but... Figure 9 In (a), portions 23a and 23b are formed continuously, and either form can be appropriately selected. Furthermore, when three first portions 23 are provided (although not shown, but for example 23a, 23b, and 23c), a transition portion can be formed between 23a and 23b, and formed continuously between 23b and 23c.

[0059] In one embodiment of the present invention, the handle component 20 for a fishing rod can be formed of carbon fiber reinforced plastic (CFRP). Alternatively, the handle component 20 can also be formed from CFRTP (continuous fiber), CFRTP (discontinuous fiber), or a hybrid fiber. By using such raw materials, sufficient rigidity and strength can be ensured for the handle component 20 used in the fishing rod, and weight gain can be suppressed.

[0060] In addition, such as Figure 4 As shown in a and 4b, in one embodiment of the fishing rod handle component 20 according to the present invention, the rod body end 13 of the fishing rod body 2 is configured to be mounted on one side of the reel seat body end 15 of the reel seat body 12, that is, on the reel seat body end 15 opposite to the grip 4. Thus, unlike many existing methods, it is not necessary for the rod body to extend beyond the entire or substantially entire fishing rod handle component 20, thereby achieving a significant reduction in weight.

[0061] In one embodiment of the present invention, the length (A) of the end 15 of the reel seat body 12 of the fishing rod handle component 20 is configured to be 20-50 mm. Thus, as described above, since it is not necessary to pass the rod body through the entire or substantially the entire fishing rod handle component 20, a significant weight reduction can be achieved. Here, the method of mounting the end 13 of the rod body 2 to the fishing rod handle component 20 can be, for example, fitting (pressing in), gluing, or fastening, but is not limited to these methods. Using the mounting methods listed herein has the advantage of facilitating the assembly and disassembly of the rod body and handle component.

[0062] Although the fishing rod handle component 20 according to one embodiment of the present invention is hollow, circumferential ribs may also be provided in the region on the side where the rod body end 13 of the fishing rod body 2 is mounted to the reel seat body 12, i.e., the reel seat body end 15 opposite to the grip 4. In this way, circumferential rigidity (compressive rigidity) can be improved while significantly reducing weight without affecting the sensitivity of the fishing rod.

[0063] In one embodiment of the present invention, an inner layer (not shown) may be provided on the inner side of the fishing rod handle component 20. In this case, a resin material can be used as the inner layer. This allows for the formation of a fishing rod handle component with a reel holder that has high processability on the inner surface and is less prone to resin deficiency and fibrous texture on the inner surface.

[0064] More specifically, because an inner layer exists on the inside of the fishing rod handle component 20, the required resin can be supplied to the fibers, thereby stabilizing the physical properties (ensuring a lower limit of strength). Furthermore, although when inserting parts into the inner layer or bonding them, additional machining of the inner diameter may be necessary depending on the size of the parts, if the inner surface is roughened, there is a problem of not being able to ensure sufficient machining allowance. However, because of the inner layer, sufficient machining allowance can be ensured, thus enabling the formation of a handle component with a softer and stronger structure.

[0065] In one embodiment of the present invention, the carbon fiber of the carbon fiber reinforced plastic (CFRP) is formed continuously along the length direction of the fishing rod handle portion. This allows for lightweighting by ensuring bending rigidity and enables sensitive transmission of rod vibrations generated by a fish being hooked to the hand.

[0066] Next, refer to Figure 8 A method for forming a handle component 20 for a fishing rod according to one embodiment of the present invention will be described. First, as Figure 8As shown in Figure a, the size and shape of the core component are determined in conjunction with the shape and size of the handle component 20 of the fishing rod (for example, offset inward by about 0.5-1 mm from the handle component 20), and a soluble core component is shaped (the shaping of the core component). The shaping method for this core component can include injection molding, casting, or formation by a 3D printer, but is not limited to these methods. Additionally, a non-soluble resin is used to cover the surface layer of the core component.

[0067] Next, as Figure 8 As shown in b, a prepreg film is laminated around the core component to form a preform. Here, an unimpregnated dry carbon fiber substrate can also be used as the laminating material.

[0068] Then, as Figure 8 As shown in c, the preform is placed in a mold, heated, pressurized, and stamped. Alternatively, it can be formed by autoclave or RTM forming, but is not limited to a specific shape.

[0069] Next, as Figure 8 As shown in d, the molded product undergoes secondary processing (dimensionalization and deburring). More specifically, this involves removing excess material from the front and back of the molded product, or removing burrs generated during the molding process.

[0070] Next, as Figure 8 As shown in Figure e, the molded product, after undergoing secondary processing, is immersed in water or warm water to dissolve the core component located inside the molded product. In this way, the handle component 20 for the fishing rod is formed. Subsequently, as... Figure 8 As shown in f, the outer surface of the handle component 20 of the fishing rod is appropriately coated or printed. Then, as... Figure 8 As shown in g, install the parts used to install the cable reel, etc. Finally, as... Figure 8 As shown in h, the reel can be mounted and fixed to the handle part 20 of the fishing rod.

[0071] Thus, a fishing rod handle component 20 according to one embodiment of the present invention can be formed, namely: a fishing rod handle component 20 having a gripping part, and a reel seat body 12 having a reel foot mounting part 12a having a reel foot 6b and a handle 4 connected to the reel seat body 12 integrally formed.

[0072] According to one embodiment of the present invention, the handle component 20 for a fishing rod, which is formed in this way, can greatly improve grip. In addition, it can achieve significant weight reduction by integrally molding the handle component. Furthermore, since it is integrally molded, it can reduce the attenuation of vibrations from the rod body, thereby improving the sensitivity of the fishing rod.

[0073] Next, another forming method for the fishing rod handle component 20 according to one embodiment of the present invention will be described. First, the size and shape of the core component are determined in accordance with the shape and size of the fishing rod handle component 20 (for example, offset inward from the fishing rod handle component 20 by about 0.5-1 mm) (core component design). In accordance with the size and shape of the core component, a sand-molded core component is formed using water-soluble sand.

[0074] Next, a preform is formed around the core component using unimpregnated carbon fiber. Specifically, fabrics (woven fabrics), NCF (non-crimped fabrics), braided materials (ribbons), and UD tapes can be used, but are not limited to these. Furthermore, carbon fiber needs to be shaped on the core component, but an adhesive can be used to provide adhesion. Types of adhesives include epoxy, rosin, polyamide, polyphenylene sulfide, polyetherimide, polyethersulfone, polysulfone, polyphenylene ether, polyimide, polyamideimide, phenoxy, etc., but are not limited to these. While the above example describes the use of unimpregnated carbon fiber, methods such as hand lay-up, where pre-impregnated sheets pre-impregnated with resin in carbon fiber cloth are directly laminated around the core and formed (cured). The preform is placed in a mold, and resin is injected (RTM molding method). Afterward, the sand-molded core component is removed in water. Finally, the molded part is subjected to deburring, grinding, coating, etc., to form the handle part 20 for fishing rods.

[0075] The RTM molding method offers several advantages, including minimizing resin impregnation and voids, even in complex shapes like handles, by using a casting method with low-viscosity resin. Furthermore, by using materials with better shapeability than prepregs, shaping can be achieved even in complex shapes without applying excessive loads to the fibers. Additionally, since the exterior is formed using a mold and the interior using a core material, both the exterior and interior can be molded to desired dimensions, resulting in molded articles with excellent surface finishes. As such, quality stabilization and the avoidance of insufficient strength can be achieved in the RTM molding method.

[0076] Next, another molding method for the fishing rod handle component 20 according to one embodiment of the present invention will be briefly described. First, a mold is prepared to be molded to fit the shape and size of the fishing rod handle component 20. As a preform, a prepreg film is placed in the mold and pressed onto the outer mold inside the mold using air pressure (internal pressure molding) to form a molded article. Subsequently, the molded article is subjected to deburring, grinding, coating, etc., to form the fishing rod handle component 20. In this internal pressure molding method, by pressing the prepreg film onto the mold (outer mold) using internal pressure, the outer surface of the molded article can be formed better. In addition, since a molded article with less resin can be produced by using a prepreg film, the product can be made lighter.

[0077] The dimensions, raw materials, and configurations of the constituent elements described in this specification are not limited to those explicitly stated in the embodiments. These constituent elements can be modified within the scope of this invention to have arbitrary dimensions, raw materials, and configurations. Furthermore, constituent elements not explicitly stated in this specification may be added to the described embodiments, and some constituent elements described in each embodiment may be omitted.
