Specific details for implementing the invention

[0021] Hereinafter, embodiments of a fishing line guide according to the present invention and a fishing rod equipped with said fishing line guide will be described in detail with reference to the attached drawings. Common components in a plurality of drawings are given the same reference numerals throughout the plurality of drawings. Please note that for the convenience of explanation, each drawing may not necessarily be depicted at an accurate scale.

[0022] FIG. 1 is a drawing showing an embodiment of a fishing rod according to the present invention. As illustrated, a fishing rod (1) according to an embodiment of the present invention comprises a rod body (2), a reel (6) installed on the rod body (2) through a reel seat (9), and a fishing line guide (10) installed on the rod body (2). In the illustrated embodiment, the reel seat (9) and the fishing line guide (10) each correspond to an installation part installed on the outer surface of the rod body.

[0023] The rod body (2) is constructed by connecting, for example, a main section (3), a middle section (5), and a tip section (7). Each of these rod bodies is joined together, for example, in a parallel manner. The main section (3), the middle section (5), and the tip section (7) may be joined in a forward manner, a reverse parallel manner, a spigot ferrule manner, or any other known joining method. The rod body (2) may be composed of a single rod body.

[0024] The main body (3), middle body (5), and top body (7) are composed of, for example, tubular bodies made of fiber-reinforced resin. These tubular bodies made of fiber-reinforced resin are manufactured by winding a fiber-reinforced resin prepreg (prepreg sheet), in which a matrix resin is impregnated into reinforcing fibers, onto a core metal, and then heating and curing the prepreg sheet. As the reinforcing fibers included in the prepreg sheet, for example, carbon fibers, glass fibers, and any other known reinforcing fibers may be used. As the matrix resin included in the prepreg sheet, a thermosetting resin such as epoxy resin may be used. After the prepreg sheet is cured, the core is decored. Additionally, the outer surface of the tubular body is appropriately polished. Each rod body may be composed of a solid shape.

[0025] 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)) that guide the fishing line drawn from the reel (6) mounted on the reel seat (9). More specifically, a fishing line guide (10A) is provided on the main rod (3), a fishing line guide (10B) is provided on the middle rod (5), and a fishing line guide (10C) is provided on the tip rod (7). A top guide (10D) is provided at the tip of the tip rod (7), but details are omitted.

[0026] Next, a fishing line guide (10) according to an embodiment of the present invention will be described with reference to FIGS. 2 to 7. FIG. 2 is a perspective view of a fishing line guide (without a guide ring) according to an embodiment of the present invention, FIG. 3 is a longitudinal cross-sectional view of the fishing line guide, and FIG. 4 is a perspective view of a fishing line guide (with a guide ring) according to an embodiment of the present invention. In addition, FIG. 5(a) is a drawing showing a part of the ring holding support portion of the fishing line guide according to an embodiment of the present invention, FIG. 5(b) is an enlarged view of a part of the ring holding support portion of the fishing line guide according to an embodiment of the present invention, and FIG. 5(c) is a cross-sectional view of the ring holding support portion of the fishing line guide according to an embodiment of the present invention as seen in the ZZ cross-section of FIG. 5(a). In addition, FIG. 6 is a drawing showing a gate mark of a guide body of a fishing line guide according to one embodiment of the present invention, and FIG. 7 is a drawing showing a contour shape defining a through hole of a guide body of a fishing line guide according to one embodiment of the present invention.

[0027] As shown in FIG. 3, the fishing line guide (10) comprises a guide body (11) and an annular guide ring (12) installed on the guide body (11). The guide body (11) comprises a leg portion (13) installed on any one of a rod body (3), a rod body (5), or a rod body (7), and a plate-shaped ring-holding support portion (14) connected to the leg portion (13). As shown in FIG. 4, the annular guide ring (12) is typically fixed to the inner circumference of the ring-holding support portion (14) through an adhesive (adhesive layer) (21). Additionally, the adhesive (adhesive layer) (21) is typically 0.1 mm or less. Please note that in FIG. 3 and FIG. 4, the gap is shown larger for convenience in order to more clearly show the appearance of the guide ring (12) and the ring-holding support portion (14). For convenience of explanation, the following description uses the case where the fishing line guide (10) is installed on the rod body (5) as an example.

[0028] In one embodiment of the present invention, the leg portion (13) is a slender, long plate-shaped or tongue-shaped member extending along the outer surface of the rod body (5). The leg portion (13) is wound onto the rod body (5) by a coil formed, for example, of nylon fiber. FIG. 2 illustrates a single-foot type fishing line guide installed on the rod body by one leg portion, but the guide ring to which the present invention can be applied is not limited to this single-foot type. For example, the present invention can also be applied to a double-foot type guide ring. The double-foot type fishing line guide has a pair of leg portions extending forward and rearward, respectively, from a ring-holding support portion, and is fixed to the rod body by this pair of leg portions. Furthermore, the present invention can be applied to either a fixed fishing line guide or a movable fishing line guide (sometimes called a movable guide).

[0029] In one embodiment of the present invention, the ring-holding support member (14) is extended from the upper end of the leg member (13). The ring-holding support member (14) is inclined upward from the rear of the rod body (5) toward the front. That is, when the guide (10) is installed on the rod body (5), the ring-holding support member (14) assumes a position tilted toward the front of the rod body (5). As illustrated, a through hole is formed in the ring-holding support member (14) that penetrates the ring-holding support member (14) approximately in the front-rear direction of the rod body (5). This through hole is defined by the inner circumferential surface (14a) of the ring-holding support member (14). The guide ring (12) is inserted into this through hole. The ring-holding support member (14) is a roughly flat plate-shaped member, but the portion connecting to the leg member (13) is gently curved as shown in FIG. 3. That is, the ring holding support (14) includes a roughly flat portion with a through hole formed into which the guide ring (12) is inserted, and a gently curved portion connected to the leg portion (13).

[0030] The leg portion (13) and ring-holding support portion (14) of the fishing line guide (10) can be formed as a single unit by injection molding using metal or synthetic resin. Details will be described later, but during injection molding, a gate mark is inevitably formed on the inner surface where the through hole of the ring-holding support portion (14) is formed. Conventionally, in order to insert the guide ring (12) into the ring-holding support portion (14), a process of first removing the gate mark was adopted. Here, a gate refers to the resin inlet (an inlet for filling the product part inside the mold with resin), and a gate mark refers to the remaining part of the gate portion (cut mark) that remains at the location where the gate was cut during the injection molding process. In contrast, as shown as an example in FIG. 6, in the fishing line guide (10) according to one embodiment of the present invention, a structure was discovered that allows the guide ring (12) to be inserted into the ring-holding support portion (14) and also fixed by adhesive without removing such a gate mark. Details will be described later.

[0031] As previously explained, an annular guide ring (12) is fitted into the through hole of the ring holding support (14). The guide ring (12) is typically elliptical, circular, or approximately circular in shape, but is not limited thereto. As shown in FIG. 3, the guide ring (12) has an inner ring surface (12a) that extends annularly in the circumferential direction of the guide ring (12), and an outer ring surface (12b) that extends approximately parallel to the outer ring surface (12a). The guide ring (12) is made of, for example, ceramics, metal, alloy, or a composite thereof. In the example of FIG. 3, the guide ring (12) is formed of a ceramic material. However, it should be noted that the cross-sectional shape of the guide ring (12) is not uniform and may vary depending on the material used.

[0032] Next, details of a fishing line guide (10) according to one embodiment of the present invention will be described with reference again to FIGS. 2, 3 and FIGS. 5, 6 and 7. A fishing line guide (10) according to one embodiment of the present invention is installed on a fishing rod (1), and the fishing line guide (10) comprises a guide body (11) having a through hole formed therein, a guide ring (12) that is fitted into the through hole of the guide body (11), and a gate mark (16) formed on an inner surface (15) that defines the through hole of the guide body (11) and formed to protrude into the through hole of the guide body (11) (in FIG. 6, one gate mark (16) is shown, but there may be cases where a plurality of gate marks (16) are provided), and when viewed in a direction perpendicular to the guide body (11), the contour shape (contour shape of the inner surface (15)) defining the through hole of the guide body (11) has one or a plurality of convex upper portions (18) (in the example shown in FIG. 5, one convex upper portion (18)) that protrude outwardly in the diameter direction from a circle. It is formed to include, and the gate trace (16) is positioned at the location where one or more convex upper portions (18) of the corresponding through hole of the corresponding inner surface (15) that defines the corresponding through hole of the corresponding guide body (11) are formed.

[0033] The contour shape (contour shape of the inner surface (15)) defining the through hole may be, for example, an oval shape, a shape in which one or more trapezoidal shapes (or shapes in which the corners of the trapezoids are rounded) are formed as convex upper parts on the circle, a shape in which one or more small-diameter circular shapes are formed as convex upper parts on the circle, a shape in which one or more triangular shapes (or shapes in which the corners of the triangular shapes are rounded) are formed as convex upper parts on the circle, or a shape in which one or more square shapes (or shapes in which the corners of the square shapes are rounded) are formed as convex upper parts on the circle, but is not limited to these. The contour shape (20) (contour shape of the inner surface (15)) defining the through hole is composed of a circular portion (17) and one or more convex upper parts (convex shape portions) (18). Here, the direction perpendicular to the guide body (11) refers to the direction perpendicular to the extension surface of the ring-holding support (14) of the guide body (11) (vertical axis X shown in FIG. 2). Additionally, the contour shape defining the corresponding through hole of the guide body (11) refers to the contour shape defining the corresponding through hole at the central position when viewed in the direction of the vertical axis X of the inner circumferential surface (15) of the guide body (11).

[0034] According to a fishing line guide (10) and a fishing rod having the fishing line guide according to one embodiment of the present invention, in a fishing line guide formed by injection molding, a guide ring can be mounted on the guide body without removing the gate trace, thereby making the gate trace removal process unnecessary, so that the conventional process can be effectively simplified and a low cost can be achieved, and by utilizing the gate trace that was previously removed, it is possible to provide a fishing line guide and a fishing rod having the fishing line guide that contributes to improving the adhesive strength between the guide body and the guide ring.

[0035] In a fishing line guide (10) according to one embodiment of the present invention, when a plurality of gate marks (16) are formed, one or a plurality of convex upper portions (18) are formed in proportion to the number (16) of the gate marks formed. In this way, the space between the guide body and the guide ring can be utilized to accommodate the gate marks (16) and also prevent them from being visible from the outside. As a result, by making the gate mark removal process unnecessary, the conventional process can be effectively simplified and a low-cost reduction can be achieved. In a fishing line guide (10) according to one embodiment of the present invention, when a plurality of gate marks (16) are formed, the gate marks (16) are formed at the positions of 0 o'clock and 6 o'clock, 0 o'clock, 4 o'clock, and 8 o'clock, or 0 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock, for example, when the position shown in the gate marks (16) of FIGS. 5 and 6 is considered as 0 o'clock and viewed like a clock.

[0036] As shown in FIG. 7, in a fishing line guide (10) according to one embodiment of the present invention, one or more convex upper portions (18) are crescent-shaped (in the illustrated example, two convex upper portions each form a crescent shape). In this way, the space between the guide body and the guide ring can be utilized to accommodate the gate trace (16) and also keep it invisible from the outside. As a result, the gate trace removal process becomes unnecessary, thereby effectively simplifying the conventional process and enabling the achievement of low cost. Additionally, in a fishing line guide (10) according to one embodiment of the present invention, one or more convex upper portions (18) may be, for example, triangular, square, trapezoidal, or circular in shape.

[0037] As shown in FIG. 5(b), in a fishing line guide (10) according to one embodiment of the present invention, the gate mark (16) is formed such that the maximum height (D1) is in the range of 0.1 mm to 1.0 mm. The reason for this is that if the height of the gate mark is too small, it becomes difficult to exert an effect as an anchor, while if the height of the gate mark is too large, the clearance between the ring and the frame increases, and the adhesive strength decreases. In this way, the gate mark (16) can be accommodated by utilizing the space between the guide body and the guide ring and also made invisible from the outside.

[0038] As previously described, FIG. 5(c) is a cross-sectional view of the ring-holding support portion (14) of the guide body (11) as seen in the ZZ cross-section of FIG. 5(a). In a fishing line guide (10) according to one embodiment of the present invention, the gate mark (16) is formed at a position that does not overlap with the central position (position shown in FIG. 5(c), which is the position shown as position AC in FIG. 5(c)) or the two end positions of the inner surface (positions A1 and A2 in FIG. 5(c)) when viewed in a direction perpendicular to the guide body (11) (direction of the vertical axis X in FIG. 2) that defines the through hole of the guide body (11). In this way, the gate mark does not appear on the surface when the ring is bonded, resulting in a beautiful appearance.

[0039] The maximum height (L1) and maximum height (D1) are as shown in FIG. 5(b) and FIG. 7. In a fishing line guide (10) according to one embodiment of the present invention, one or more convex upper portions (18) have a maximum height (L1) greater than or equal to the maximum height (D1) of the gate trace. Here, the maximum height (L1) of one or more convex upper portions (18) is formed to be, for example, in the range of 0.1 mm to 1.0 mm. In this way, the gate trace (16) can be accommodated using the space between the guide body and the guide ring and also made invisible from the outside. As a result, the gate trace removal process is made unnecessary, thereby effectively simplifying the conventional process and enabling the achievement of low cost.

[0040] As shown in FIG. 3, in a fishing line guide (10) according to one embodiment of the present invention, a guide ring (12) is formed such that a gap is created between its outer surface (12b) and the inner surface (15) of the ring holding support part (14) of the guide body (11) (the gap contains an adhesive (adhesive layer) (21), and a gate mark (16) is formed between the outer surface (12b) of the guide ring (12) and the inner surface (15) of the ring holding support part (14) of the guide body (11). In this way, the space between the guide body and the guide ring can be utilized to accommodate the gate mark (16) and also keep it invisible from the outside. As a result, the gate mark removal process becomes unnecessary, thereby effectively simplifying the conventional process and enabling the achievement of low cost.

[0041] A fishing line guide (10) according to one embodiment of the present invention further comprises an adhesive disposed in the gap. In this way, it becomes possible to adhesively fix the guide ring (12) to the ring holding support (14) of the guide body (11).

[0042] A fishing rod (1) according to one embodiment of the present invention is configured to have at least one of the above fishing line guides (10). According to the fishing rod (1) having a fishing line guide (10) according to one embodiment of the present invention, in a fishing line guide formed by injection molding, a guide ring can be mounted on the guide body without removing the gate trace, thereby making the gate trace removal process unnecessary, so that the conventional process can be effectively simplified and a low cost can be achieved, and by utilizing the gate trace that was previously removed, it is possible to provide a fishing line guide and a fishing rod having said fishing line guide that contributes to improving the adhesive strength between the guide body and the guide ring.

[0043] The dimensions, materials, and arrangements of each component described herein are not limited to those explicitly described in the embodiments, and each component may be modified to have any dimensions, materials, and arrangements that may be included within the scope of the invention. Additionally, components not explicitly described herein may be added to the described embodiments, and some of the components described in each embodiment may be omitted. Explanation of the symbols
