  By the way, such a cylindrical member, especially a reel sheet having directionality, needs to be positioned in the circumferential direction with respect to the flange, and the reel sheet positioned in the circumferential direction is held in that position. It is necessary to bond and fix it as it is. However, the prior art including the above cited references does not have a technical idea of maintaining the circumferential position of the reel sheet at the bonding stage, and the reel sheet is not attached to the bag unless the bonding operation is carefully performed. There is a possibility that problems such as bonding that is offset in the circumferential direction or that the reel sheet is eccentrically bonded from the center of the flange may occur.

  In addition, it is troublesome to form the protrusions on the cylindrical member or the ridge by machining for adhesion between the ridge and the cylindrical member as in the cited documents 1 and 2 described above, which increases the manufacturing cost. Result.

  The present invention has been made paying attention to the above-described problem, and can be accurately positioned in the circumferential direction with respect to the flange, and can be inexpensively provided with an adhesive structure that can be bonded while maintaining the position. The purpose is to provide fishing rods.

  In order to achieve the above-described object, the present invention provides a fishing rod in which a cylindrical member is bonded to the outer periphery of the rod, and at least one convex portion extending in the longitudinal axis direction of the rod is provided on the outer surface of the rod. And a recess that engages with at least one of the protrusions is provided on an inner surface of the cylindrical member that is loosely fitted to the outer periphery of the flange, and the protrusion and the recess are engaged to form the flange. The cylindrical member is positioned and bonded and fixed to the flange in the circumferential direction by interposing an adhesive in the gap between the outer peripheral surface of the flange and the inner peripheral surface of the cylindrical member. Features.

  According to the fishing rod having the above-described configuration, the convex portion provided on the outer surface of the rod and the concave portion provided on the inner surface of the cylindrical member are engaged with each other, so that the gap between the outer peripheral surface of the rod and the inner peripheral surface of the cylindrical member. By filling the gap with an adhesive, the cylindrical member can be accurately positioned in the circumferential direction with respect to the flange, and can be bonded in a state in which the position is maintained. Moreover, if the convex part is formed by a printing process including screen printing and ink jet printing, the manufacturing cost can be reduced.

Hereinafter, an embodiment of a fishing rod according to the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is an overall view showing an example of a fishing rod according to an embodiment of the present invention. The fishing rod 1 of the present embodiment is configured by joining a plurality of rods. In the present embodiment, three rods, namely, a main rod 3, a middle rod 5, and a tip rod 7. Are joined in a side-by-side manner. The structure which does not have about the intermediate collar 5 may be sufficient, or the structure which joins 4 or more may be sufficient. In addition, the fishing rod is not particularly limited in its configuration, such as a single rod, a swing rod, and a through rod, in addition to the side-by-side type.

  The main rod 3 is provided with a reel leg fixing device 10 on which a fishing reel 70 is mounted. The reel leg fixing device 10 includes a moving hood 12 and a fixed hood 14 that are spaced apart in the axial length direction. One end of the reel leg 70a is inserted into the fixed hood 14, and the other end of the reel leg 70a is moved in the axial direction. By pressing with 12, the fishing reel 70 can be fixed to the rod. The fixed hood 14 and the movable hood 12 are disposed on a reel sheet 15 as a cylindrical member that is attached to the outer periphery of the main shaft 3.

  Each rod is provided with a plurality of fishing line guides 8 (the tip of the tip rod 7 is a top guide 8a) for guiding the fishing line fed out from the fishing reel 70 at a predetermined interval. The fishing line guide 8 may be configured as a fixed guide fixed to the rod or may be configured as an idle guide that can slide along the rod.

  FIG. 2 shows an adhesive structure between a main rod (hereinafter simply referred to as a rod) 3 and a reel sheet 15 in the fishing rod 1 of the present embodiment. In FIG. 2, only the bonding area of the flange 3 is shown as a perspective cross section, and only the main cross section of the reel sheet 15 is shown for ease of illustration.

  As shown in the figure, in this bonding structure, at least one (one in this embodiment) convex portion 20 extending in the longitudinal axis direction of the flange 3 is provided on the outer surface 3a of the bonding region of the flange 3, and A concave portion 40 that engages with the convex portion 20 is provided along the longitudinal axis direction of the reel sheet 15 on the inner surface 15a of the reel sheet 15 that is loosely fitted on the outer periphery of the flange 3 (so as to enable desired circumferential positioning). It is done. In this case, the length (dimension along the longitudinal direction) of the concave portion 40 may coincide with the length of the convex portion 20, or may be longer or shorter than the length of the convex portion 20.

  The convex portion 20 is made of, for example, a resin and is preferably formed by a printing process such as screen printing or inkjet printing, but may be formed by machining. Forming the convex portion 20 by printing is advantageous because, when the reel sheet 15 is molded by casting, a desired convex shape can be easily and inexpensively formed according to the mold of the reel sheet 15.

  In addition, the protrusion height of the convex part 20 is set to 0.03 mm-0.2 mm, for example, 0.1 mm, for example. However, the convex part 20 can set the shape and dimension arbitrarily. Further, the convex portion 20 and the concave portion 40 only need to be hooked and engaged in the circumferential direction (the reel sheet 15 only needs to be positioned in the circumferential direction of the flange 3), and does not need to be closely fitted to each other (unevenness) It is not necessary that the portions 20 and 40 have the shape and dimensions that completely coincide with each other (see, for example, FIG. 10B). Further, the inner diameter dimension of the reel sheet 15 is slightly larger than the outer diameter dimension of the collar 3 so that a gap can be formed between the inner surface 15 a of the reel sheet 15 and the outer surface 3 a of the collar 3. It is set (see, for example, FIG. 10B).

  Therefore, in the above configuration, for example, an adhesive is applied in advance to the outer surface 3a of the bonding region of the flange 3, and the reel sheet 15 is folded so that the convex portion 20 and the concave portion 40 are engaged in this state. 3, the reel sheet 15 is positioned in the circumferential direction with respect to the flange 3, and the adhesive is interposed between the outer surface 3 a of the flange 3 and the inner surface 15 a of the reel sheet 15. It can be bonded and fixed by action. An example of the adhesive fixing state is shown in FIG.

  Here, FIG. 10 shows a formation form (FIG. 10A) of an adhesive layer (adhesive 100) between the flange 3 and the reel sheet 15 in an example of the prior art, and the flange 3 in the present embodiment. 10 shows a comparison of the form of formation of the adhesive layer (adhesive 100) between the reel sheet 15 and the reel sheet 15 (FIG. 10B).

  In the conventional form shown in FIG. 10A, the recess 40 is formed on the inner surface 15a of the reel sheet 15, and the adhesive layer is formed so that the adhesive 100 enters the recess 40. In the conventional configuration, for example, when a rotational moment acts on the reel sheet 15, the adhesive portion 100a that has entered the recess 40 is broken from other portions of the adhesive layer or bonded to the outer surface 3a of the flange 3. There is a possibility that peeling occurs at the interface between the layers, and the adhesive fixing state between the flange 3 and the reel sheet 15 is released.

  On the other hand, the bonding form of the present embodiment shown in FIG. 10B (the concavo-convex portions 20, 40 do not have a shape and dimensions that completely match, and only the upper end portion 20a of the convex portion 20 is in the concave portion 40. Engaged adhesion form (a loose engagement state in which the concave and convex portions 20, 40 are engaged via the adhesive 100). In this case, the adhesive portion 100a that has entered the recess 40 is restricted from breaking even when a rotational moment acts on the reel sheet 15 due to the engagement between the concave and convex portions 20, 40. In addition, since the interface with the adhesive layer does not exist due to the presence of the convex portion 20, particularly at the flange portion facing the concave portion 40, peeling does not occur, and accordingly the wrinkle is accompanied by the action of an external force such as the rotational moment. 3 and the reel sheet 15 It is possible to prevent the wearing fixed state is released.

  FIG. 3 shows a first modification of the bonding structure between the flange 3 and the reel sheet 15. As shown in the figure, in this modification, two convex portions 20, 22 similar to those of the above-described embodiment are provided on the outer surface 3a of the flange 3 so as to be spaced apart from each other in the circumferential direction of the flange 3, and the convex portions 20, Corresponding to the position 22, recesses 40, 42 are provided on the inner surface 15 a of the reel sheet 15. In this modification, the convex portions 20 and 22 and the concave portions 40 and 42 are provided at an angular interval of 90 ° in the circumferential direction, but the circumferential direction of the convex portions 20 and 22 (and hence the concave portions 40 and 42). The spacing interval can be set arbitrarily. Moreover, the convex parts 20 and 22 spaced apart in the circumferential direction do not need to have the same size and shape, and their width, length, shape, protruding height, and the like may be different. Moreover, in this modification, the number of convex parts is two, but three or more may be provided. Even with such a configuration, the same effects as those of the above-described embodiment can be obtained.

  FIG. 4 shows a second modification of the bonding structure between the collar 3 and the reel sheet 15. As shown in the figure, this modified example is shown with the convex portions 20 and 22 (shown in black) spaced apart from each other in the circumferential direction of the first modified example shown in FIG. The same) in the axial direction. That is, a plurality of convex portions 20 (20a, 20b, 20c, 20d) and 22 (22a, 22b, 22c, 22d) are provided on the outer surface 3a of the flange 3 so as to be spaced apart from each other in the circumferential direction. The parts 20a, 20b, 20c, and 20d (22a, 22b, 22c, and 22d) are provided apart from each other in the longitudinal axis direction of the flange 3.

  Moreover, the recessed parts 40 and 42 provided in the inner surface 15a of the reel sheet 15 are provided in the same manner as the first modified example shown in FIG. That is, these recesses 40 (42) are simultaneously located with all of the plurality of protrusions 20a, 20b, 20c, 20d (22a, 22b, 22c, 22d) that are located at corresponding circumferential positions and are spaced apart in the longitudinal axis direction. The reel sheet 15 extends in the axial direction so that it can be engaged.

  In such a configuration, an adhesive is applied in advance to the outer surface 3a of the bonding region of the collar 3, and in this state, as shown in FIG. 4B, the convex portion 20 (22) and the concave portion 40 (42). When the reel sheet 15 is inserted into the outer periphery of the flange 3 so as to engage with each other, the plurality of convex portions 20a, 20b, 20c, 20d (22a, 22b, 22c, 22d) spaced apart in the longitudinal axis direction The gap S formed therebetween functions as an adhesive reservoir, and the adhesive force can be greatly improved.

  FIG. 5 shows a third modification of the bonding structure between the collar 3 and the reel sheet 15. As shown in the figure, in this modification, a plurality of convex portions 20c, 20d; 22a, 22b, 22c, 22d; 24b, 24c, 24d; 26c, 26d are formed on the outer surface 3a of the flange 3 as in the second modification. Are arranged so that the number of convex parts 20, 22, 24, 26 spaced apart in the circumferential direction is different along the axial direction. Specifically, the number of convex portions gradually increases along the direction X in which the reel sheet 15 is inserted into the flange 3 (for example, one (22a) as shown in FIG. 2 (22b, 24b) → 4 (20c, 22c, 24c, 26c) → 5 or more (20d, 22d, 24d, 26d,..., And so on). In this case, the reel sheet 15 has convex portions 20c, 20d; 22a, 22b, 22c, 22d; 24b, 24c, 24d; 26c, 26d. . . . Of recesses 40, 42, 44, 46. . . . . Are spaced apart in the circumferential direction.

  Usually, an adhesive is applied in advance to the outer surface 3a of the adhesion region of the collar 3, and in this state, the reel sheet 15 is folded so that the convex part and the concave part engage with each other as indicated by an arrow in FIG. When the flange 3 is inserted into the outer periphery, the adhesive is rubbed by rubbing between the outer surface 3a of the flange 3 and the inner surface 15a of the reel sheet 15 due to the insertion operation, and the upstream side in the insertion direction X is bonded. The amount of adhesive applied decreases (thus, the upstream side becomes defective in adhesion), but the degree of adhesive squeezing by reducing the number of projections on the upstream side in the insertion direction X as in this modification. If the distance is made smaller toward the upstream side, poor adhesion on the upstream side in the insertion direction can be avoided, and adhesion can be performed uniformly throughout the entire adhesion region.

  By the way, as described above, the inner diameter of the reel sheet 15 is set so that a gap can be formed between the inner surface 15a of the reel sheet 15 and the outer surface 3a of the flange 3 so that an adhesive can be interposed. Since it is set to be slightly larger than the dimension, depending on the state of adhesion (or due to the weight of the flange 3 and the reel sheet 15), the reel sheet 15 is positioned relative to the center of the flange 3 as shown in FIG. There may be a case where bonding is performed in an eccentric state (the distribution form of the adhesive 100 is biased in the circumferential direction).

  Therefore, in order to avoid such a situation, in the fourth modified example of the bonding structure between the flange 3 and the reel sheet 15 shown in FIG. The first convex portion 20H (extending in the longitudinal axis direction of the flange 3 in FIG. 7) that can be engaged with the concave portions 40, 42, 44, and 46 of the sheet 15, and the protruding height is higher than that of the first convex portion 20H. The lower second convex portion 20L (in FIG. 7, it extends in the longitudinal axis direction of the reel sheet 15). Specifically, the first convex portion having a high protruding height that engages with the concave portions 40, 42, 44, 46 of the reel sheet 15 so that the reel sheet 15 can be positioned substantially concentrically on the outer periphery of the flange 3. For example, four protrusions 20H are provided in the circumferential direction of the flange 3 so as to be opposed to each other in the radial direction at an angular interval of 90 °, and the second protrusions having a low protrusion height between the first protrusions 20H. 20L is provided.

  In the present modification, the first convex portion 20H contributes to the concentric arrangement of the reel sheet 15 with respect to the flange 3, but the second convex portion 20L has a uniform adhesive pool (over the entire circumference of the flange 3). Helps to form gaps). Therefore, as shown in FIG. 8A, the second convex portions 20L may be provided apart from each other in the longitudinal axis direction of the flange 3, or the adhesive may be provided in the circumferential direction of the flange 3. In order to evenly disperse the adhesive in the bonding region in such a manner as to flow in the longitudinal direction of the collar 3 while being spaced apart from each other in the longitudinal axis direction of the collar 3 as shown in FIG. It may extend obliquely at an angle.

  Moreover, in the above structure, the convex parts 20, 22,. . . Is formed by a printing process such as screen printing. Of course, the convex portion may be formed by machining. In that case, as shown in FIG. 9 (a), the flange 3 is formed thicker in advance than the desired outer diameter (for example, one extra prepreg as a material for forming the flange 3 is added. The protrusions 20, 22, 24,... Are cut off by cutting the predetermined portion P of the outer surface 3a by the thickness of the thickened surplus. . . May be formed (see FIG. 9B).

  As mentioned above, although embodiment of this invention was described, this invention can be variously modified and implemented in the range which does not deviate from the summary. For example, the arrangement form, shape, size, and the like of the convex portions and the concave portions can be arbitrarily set, and are not limited to the above-described embodiments. Moreover, it is not necessary for all the convex portions to engage with the concave portions. In the above-described embodiment, the reel sheet is exemplified as the cylindrical member, but the cylindrical member is not limited to the reel sheet (for example, a fishing rod gripping part or the like).
