Description

Technical Field

[0001] The present invention relates to a fishing rod having features on a handle portion. Background Art

[0002] In the past, a handle for holding during actual fishing was installed at the base end of the fishing rod. The handle is known to have various structures. For example, in a fishing rod used for crucian carp fishing, as disclosed in Patent Document 1, a step eliminating layer (connecting portion) is provided to eliminate the step between the handle installed on the rod and the surface of the rod. Figure 5 As shown in the reference numeral 60 of (a) and (b), the step-eliminating layer (connecting portion) disclosed in the above-mentioned patent document 1 is provided in the axial direction with a predetermined length on the surface of the rod 50 from the top edge 51a of the grip 51 mounted on the outside of the base end side of the rod (first section rod) 50. In addition, such a step-eliminating layer (connecting portion) 60 is provided so as to become thinner as a resin coating is applied to the top end by brushing or the like.

[0003] Patent Literature Patent Document 1: Japanese Patent Application Publication No. 2003-310111 Summary of the invention

[0004] When the above-mentioned conventional handle is subjected to bending stress during actual fishing, the stress is likely to be concentrated at the boundary between the connection portion 60 and the handle 51 ( Figure 5 (a)(b) The portion indicated by the arrow D is formed on the surface of the connecting portion 60, so there is a problem that cracks are easily generated on the surface of the connecting portion 60. In particular, since the wall thickness of the connecting portion is thin, the generated cracks are easily expanded when the fishing rod is bent. In addition, when cracks are generated in the connecting portion, the connecting portion is damaged, etc., which deteriorates the appearance.

[0005] The present invention is made with an eye to the above-mentioned problems, and the technical problem to be solved is to provide a fishing rod having a connecting portion at the top end of a handle, in which cracks are not easily generated on the surface of the connecting portion and the amount of resin used for the connecting portion can be reduced.

[0006] In order to achieve the above-mentioned purpose, the fishing rod involved in the present invention is a fishing rod with a handle installed on the outer peripheral surface of the base end side of the first section of the rod, characterized in that a tubular protrusion is inserted and fixed to the surface of the first section of the rod at the top end of the handle on the rod tip side, and a resin connecting part is arranged between the top end of the handle on the rod tip side and the first section of the rod, and the connecting part covers the protrusion and is a cone that is inclined from the top edge of the handle on the rod tip side toward the surface of the first section of the rod.

[0007] According to the above-mentioned fishing rod of the present invention, since the top end of the handle on the rod tip side has a protrusion of a predetermined length, and the connecting portion is arranged to cover the protrusion, when bending stress acts, the stress can be dispersed by the top edge of the handle and the top edge of the protrusion, so it is not easy to generate cracks on the surface of the connecting portion. In addition, since the connecting portion is a tapered shape inclined toward the surface of the first rod section, the appearance of the connecting portion can be finally completed beautifully.

[0008] As described above, according to the present invention, a fishing rod having a resin connection portion provided at the tip of a handle can be provided, in which cracks are less likely to occur on the surface of the connection portion and the amount of resin used can be reduced.

[0010] (First Embodiment) Below, refer to Figure 1 and Figure 2 A fishing rod according to a first embodiment of the present invention will be described. Figure 1 This is a diagram showing the handle of a fishing rod. Figure 2 (a) and (b) are Figure 1 The central longitudinal section of the handle portion and the enlarged view of the main part are shown in FIG. Figure 1 In the middle, the upper side is the top side.

[0011] The fishing rod 1 involved in the first embodiment comprises a first rod section 2 and a rod (front rod; not shown) connected in sequence to the front side of the first rod section 2. At this time, as is well known, the front rod can be connected by a pull-out type, a plug-in type, a sleeve type, etc., and there is no restriction on the number of connections.

[0012] The first rod section 2 and the front rod are formed into a tubular shape by winding a fiber-reinforced resin material (prepreg film) in which reinforcing fibers are impregnated in a synthetic resin. Each rod may also include a solid structure formed of a superelastic alloy or superelastic resin, and may also be formed of natural materials such as bamboo.

[0013] On the base end side of the first section of the rod 2, a handle 10 (handle body 10A) is fixed by clamping a handle holding component 12 described later. The handle 10 is made of FRP, hard resin, light metal, etc. that is separate from the rod, and a fiber body (woven) is wound on its surface to facilitate the user's grip. In addition, although a step is generated between the top edge 10a of the handle 10 and the outer peripheral surface of the first section of the rod 2, a connecting portion 20 serving as a step eliminating layer is provided on the step portion, and is ultimately processed into an inclined surface without a step. In addition, there is no limitation on the raw materials constituting the handle 10 (body 10A), and in addition to the above-mentioned raw materials, it can also be composed of soft materials such as foam materials or cork.

[0014] The handle 10 is mounted on the handle holding component 12 by bonding or the like, and the handle holding component 12 is mounted on the outer peripheral surface of the base end side of the first section of the rod 2. The handle holding component 12 is made of FRP, hard resin, aluminum alloy or other light metal, is formed in a tubular shape and extends to the base end of the first section of the rod 2, and is inserted and fixed to the outer peripheral surface of the base end side of the first section of the rod 2 by an adhesive or the like. That is, the handle holding component 12 is composed of a tubular body on which the inner surface of the handle 10 is mounted over the entire axial length, thereby the handle 10 is arranged on the base end side of the first section of the rod 2 in a stable state. The top end side of the handle holding component 12 protrudes in the axial direction only by a specified length L (protruding length L) from the top end edge 10a of the mounted handle 10, thereby forming a tubular protrusion 12a.

[0015] The top edge 10a of the handle 10 has a step relative to the surface of the rod 2 (eg Figure 2 As shown in (b), the height of the step is H+H2), and a connecting portion 20 is provided on the step portion. The connecting portion 20 is tapered and gradually becomes thinner toward the top end side, and covers the protruding portion 12a.

[0016] The connection part 20 is formed by, for example, applying a UV-curable resin (paint). In particular, when the handle 10 is formed of a foamable raw material, the UV-curable resin can be easily infiltrated and the adhesion between the handle and the handle can be improved. In addition, by repeatedly applying the coating, the connection part 20 can have a thick wall and the appearance can be made smooth and beautiful in the end.

[0017] A reduced diameter portion 2a is formed at the base end side of the first rod section 2 of the present embodiment. The reduced diameter portion 2a can be formed, for example, by clamping the first rod section 2 and performing centerless machining on the rear end side, and then inserting and fixing the tubular handle holding component 12 on the machined reduced diameter portion 2a.

[0018] By forming the reduced diameter portion 2a on the first rod section 2, when the handle holding component 12 is pressed into the reduced diameter portion 2a, the end face (top edge) 12b on the top side will abut against the end face 2b on the top side of the reduced diameter portion 2a, thereby facilitating the positioning of the handle holding component 12 and achieving a stable fixed state. In addition, since a step H is formed between the surface of the first rod section 2, stress can also be concentrated on this portion (the position of the top edge 12b of the handle holding component 12).

[0019] In addition, by making the wall thickness T of the handle holding component 12 larger than the concave amount H1 of the reduced diameter portion 2a, a step H can be formed, and when bending stress acts on the first section of the rod, the stress can be concentrated. At this time, by forming the wall thickness T of the handle holding component 12 to be thicker than the wall thickness T1 of the first section of the rod 2, a step H can be effectively formed.

[0020] The connection part 20 is provided from the top edge 10a of the handle 10 to the surface of the rod 2. As described above, the connection part 20 is made of ultraviolet curing resin and is provided to cover the protrusion 12a. At this time, the connection part 20 can play a role in eliminating the step on the front side from the top edge 10a of the handle 10, and it is preferably less than 15mm in the axial length direction on the product.

[0021] Therefore, the protrusion length L of the protrusion 12a is preferably set to about half the axial length of the connection portion 20. That is, if the protrusion 12a is too long, the connection portion 20 will also become long, which may deteriorate the appearance.

[0022] In addition, in order to prevent cracks from easily occurring in the connection portion (dispersing stress concentration in the axial direction), the lower limit of the protrusion length L of the protrusion 12a is preferably 1 mm or more, more preferably 2 mm or more, and even more preferably 3 mm or more. That is, the protrusion length L of the protrusion 12a can be set to 1 mm≦L≦7 mm, preferably 2 mm≦L≦7 mm, and more preferably 3 mm≦L≦7 mm.

[0023] Thus, by ensuring the protruding length L of the protruding portion 12a to a certain extent, the points of force acting when the bending stress acts (the positions of D1 and D2) can be separated by a sufficient distance, and the stress acting on one point as in the conventional method can be concentrated ( Figure 5 (b) The position of D) is dispersed to suppress the occurrence of cracks.

[0024] If the step H is too high, the resin on the top edge of the handle holding member 12 will become thinner and cracks will be easily generated. On the contrary, if it is too low, the dispersion effect of stress concentration will be weakened, resulting in easy cracking. In addition, when the step H is reduced, the adhesion (anchoring effect) of the paint constituting the connecting portion 20 will also be reduced, and damage such as peeling will be easily generated. Therefore, it is preferable that the step H is formed to be 0.3≦H≦0.5mm.

[0025] In addition, by setting the step H and the step H2 on the top edge 10a of the handle 10 to be approximately the same, specifically to about 0.8H≦H2≦1.2H, the resin can be adhered evenly, the sense of unity can be improved visually and tactilely, the finished product can be beautiful, and stress concentration can be dispersed.

[0026] According to the handle structure of the fishing rod constructed as above, since the handle holding part 12 on which the handle 10 is mounted protrudes axially relative to the top edge 10a of the handle 10 and forms the protrusion 12a, and the connecting part 20 is arranged to cover the protrusion 12a, when bending stress acts, the stress can be dispersed axially to the top edge 10a (D1) of the handle and the top edge 12b (D2) of the protrusion 12a at a distance, so it is not easy to generate cracks on the surface of the connecting part 20. In addition, since the connecting part 20 is a tapered shape that is inclined from the top edge of the rod tip side of the handle 10 toward the surface of the first section of the rod 2, the appearance of the connecting part 20 can be finally completed beautifully.

[0027] (Second Embodiment) Figure 3 2 is a central longitudinal sectional view showing a second embodiment of the grip portion. In the following description, the same reference numerals are used for the same parts as those of the first embodiment, and detailed description thereof will be omitted.

[0028] In the second embodiment, the tubular handle holding member 12A made of FRP, hard resin, light metal, etc. is formed short, and is inserted and fixed to the surface of the first rod 2 by adhesive or the like in such a manner that about half of it protrudes from the top edge 10a of the handle 10, and the remaining half on the base end side is immersed in the inner surface of the handle 10. Thus, the handle holding member 12A can be mounted on the inner surface of the top end side of the main body 10A of the handle 10 and hold the handle 10.

[0029] In the structure of the handle holding component 12A of the present embodiment, when bending stress acts on the first section of the rod 2, the stress can be dispersed at a distance in the axial direction on the top edge 10a (D1) of the handle 10 and the top edge 12b (D2) of the handle holding component 12A, so it is not easy to generate cracks on the surface of the connecting portion 20. In addition, since it is not necessary to form the handle holding component 12A longer as in the first embodiment, the handle portion can be lightweight. In addition, the length of the protrusion 12a and the structure of the connecting portion 20 are the same as those of the first embodiment.

[0030] (Third Embodiment) Figure 4 It is a central longitudinal sectional view showing a third embodiment of the handle portion. In the third embodiment, similar to the second embodiment, the length of the tubular grip holding member 12B made of FRP, hard resin, light metal, etc. is formed to be short, and about half of it is formed as a tubular protrusion 12a protruding from the top edge 10a of the grip 10, and the remaining half on the base end side is immersed in the inner surface of the grip 10, and is inserted and fixed to the surface of the first rod 2 by adhesive or the like. In this way, the grip holding member 12B can be installed on the inner surface of the top side of the body 10A of the grip 10 and hold the grip 10.

[0031] On the surface of the protruding portion 12a, an inclined portion 12d is formed whose diameter decreases toward the tip side. In this way, by forming the inclined portion 12d on the surface of the protruding portion 12a, the wall thickness of the connecting portion 20 on this portion can be reduced, so that when the resin is applied, the resin can be prevented from expanding or sinking, and the generation of cracks can be effectively suppressed, and the finished product can be made more beautiful. In addition, the length of the protruding portion 12a and the structure of the connecting portion 20 are the same as those of the first embodiment.

[0032] (Fourth Embodiment) Figure 5 It is a central longitudinal sectional view showing a fourth embodiment of the handle portion. Although the above-mentioned first to third embodiments show a structure in which a reduced diameter portion 2a is formed on the base end side of the first rod section 2 and the handle holding component 12 is inserted and fixed into the reduced diameter portion 2a, in the fourth embodiment, the reduced diameter portion 2a is not formed on the base end side of the first rod section 2, but a tubular handle holding component 12 made of FRP, hard resin, light metal, etc. is directly inserted and fixed to the surface of the first rod section 2 on the first rod section 2 by an adhesive or the like.

[0033] Since the thickness T1 (not shown) of the grip holding member 12 (protruding portion 12a) in the fourth embodiment corresponds to the step H in the first embodiment, it is preferably 0.3≦T1≦0.5 mm.

[0034] Although in Figure 5 In the example shown, there is Figure 2 In the same manner, the tubular handle holding member 12 is formed to be long along the axial direction of the handle 10, but it is also possible to Figure 3 , 4 The same but shorter, and as Figure 4 As shown in FIG. 1 , a tubular protrusion 12a may have an inclined portion 12d. The length of the protrusion 12a and the configuration of the connection portion 20 are the same as those of the first embodiment.

[0035] (Fifth Embodiment) Figure 6 It is a central longitudinal sectional view showing a fifth embodiment of the handle portion. Although in the above-mentioned first to fifth embodiments, a part of the grip holding member 12 which is separate from the grip body 10A is used to form the protrusion 12a, the fifth embodiment forms a tubular protrusion 12a which is integral with the grip body 10A (molded in one piece) and protrudes toward the tip of the rod.

[0036] Since the thickness T2 (not shown) of the protruding portion 12a in the fifth embodiment corresponds to the step H in the first embodiment, it is preferably 0.3≦T2≦0.5 mm.

[0037] Since the grip body 10A is made of FRP, hard resin, light metal, etc., and the protrusion 12a protruding from the grip body 10A is also made of the same FRP, hard resin, or light metal, the connection part 20 covers the protrusion 12a, so that cracks are not easily generated on the surface of the connection part 20. In addition, the length of the protrusion 12a and the structure of the connection part 20 are the same as those of the first embodiment.

[0038] (Sixth Embodiment) Figure 7 It is a central longitudinal sectional view showing a sixth embodiment of the handle portion. In the present embodiment, the handle holding component 12 as in the first to fourth embodiments is not used, but the protrusion 12a is inserted and fixed to the surface of the first section of the rod 2 by means of an adhesive or the like in such a way that the base end side of the protrusion 12a abuts against the top end 10a of the handle 10 on the rod tip side. The protrusion 12a is composed of a tubular body separate from the handle 10. Similar to the handle holding component 12 in the first to fourth embodiments, the protrusion 12a is made of FRP, hard resin, light metal, etc., and is inserted and fixed to the surface of the first section of the rod 2 by means of an adhesive or the like.

[0039] As in the fifth embodiment, the thickness T3 (not shown) of the protrusion 12a in the sixth embodiment is preferably set to 0.3≦T3≦0.5 mm, and the length of the protrusion 12a and the configuration of the connection portion 20 are the same as in the first embodiment.

[0040] (Seventh Embodiment) Figure 8 It is a central longitudinal sectional view showing a seventh embodiment of the handle portion. Although the protrusion 12a involved in this embodiment is the same as the sixth embodiment in that its base end side is in contact with the top end 10a of the handle 10 on the rod tip side and is inserted and fixed to the surface of the first section of the rod 2 by adhesive or the like, a plurality of step surfaces 32a, 32b that decrease in diameter toward the top end are formed on its surface, which is different from the sixth embodiment. By forming a plurality of step surfaces 32a, 32b, the amount of resin used (number of coatings) constituting the connection portion 20 can be further reduced, and the connection portion 20 above the step surfaces 32a, 32b can be thinned, thereby facilitating the coating operation and enabling the surface to be finally processed beautifully. In addition, due to the presence of a plurality of step portions, the anchoring effect of the connection portion 20 can be improved.

[0041] As in the fifth embodiment, the maximum thickness T4 (not shown) of the protrusion 12a in the seventh embodiment is preferably 0.3≦T4≦0.5 mm, and the length of the protrusion 12a and the configuration of the connection portion 20 are the same as in the first embodiment.

[0042] (Eighth Embodiment) Fig. 9 It is a central longitudinal sectional view showing an eighth embodiment of the grip portion. Although the protrusion 12a involved in this embodiment is the same as the sixth embodiment in that its base end side is in contact with the top end 10a of the rod tip side of the handle 10 and is inserted and fixed to the surface of the first section of the rod 2 by adhesive or the like, an inclined surface 42a is formed on its surface that becomes thinner as it transitions to the top end, which is different from the sixth embodiment. By setting the inclined surface 42a to the same inclination angle as the surface shape of the connecting portion 20, the wall thickness can be effectively reduced (further reducing the amount of resin used), and since the coating is performed along the inclined surface 42a, the resin coating operation can be facilitated and the surface can be finally processed beautifully.

[0043] As in the fifth embodiment, the maximum thickness T5 (not shown) of the protrusion 12a in the eighth embodiment is preferably 0.3≦T5≦0.5 mm, and the length of the protrusion 12a and the configuration of the connection portion 20 are the same as in the first embodiment.

[0044] In addition, the above-mentioned step surfaces 32a, 32b and inclined surface 42a may be formed on the surface of the same protrusion 12a, and the inclined surface may be formed on the surface of the step surface.

[0045] Although the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications are possible. The material and structure of the main body 10A of the handle 10 are not particularly limited. For example, the surface may be made of a resin material, and a lightweight material may be filled inside to adjust the hardness when gripped, or a composite material may be used to prevent surface damage. In addition, the handle holding member 12 only needs to hold the handle 10, and may not be composed of a tubular body.

[0046] In addition, the protrusion only needs to protrude from the top edge 10a of the handle 10 to the top end side in the axial direction by a predetermined length, and the protrusion is covered by the connecting portion 20, and its structure can be appropriately modified. In addition, the connecting portion 20 can also be a transparent resin or a transparent resin with a color, and its installation method can also be appropriately modified.
