Description

Technical Field

[0001] This invention relates to a balancer (fishing rod weight) attached to a fishing rod for adjusting the action or balance of the fishing rod, and a fishing rod equipped with the same.

Background Art

[0002] There is an element called "action" in determining the specifications of a fishing rod. Primarily, action means the deflection curve of the entire fishing rod when tensile force or bending moment acts on the blank, and the action is classified according to the position where the inflection point appears. For example, in a "tip-action" fishing rod, the inflection point appears on the tip side of the fishing rod, and the rod has tension throughout, making it generally easy to handle. Anglers can easily perform rigging, lure casting, and line operations. On the other hand, a "butt-action" fishing rod bends significantly as a whole when receiving a bending moment and can softly receive the tensile force of the targeted object. By designing such "action", various fishing pleasures can be realized according to the target or the specifications of the rig used.

[0003] Once this "action" is designed, it becomes unique to that fishing rod. However, for example, in noodle fishing, since a thin and light rig is used, a butt-action is required for the fishing rod considering the capture of the target. On the other hand, since a relatively heavy kneaded bait is used, a certain rigidity is required at the tip when casting the rig. In order to meet such requirements, balance adjustment members (weights) attached to the fishing rod have been proposed (see, for example, Patent Document 1 and Patent Document 2).

Summary of the Invention

[0005] The balance adjustment members 24 and 28 disclosed in Patent Document 1 change the center of gravity and action of the fishing rod by being fixed at a predetermined position on the fishing rod. However, since the position of these balance adjustment members relative to the fishing rod cannot be changed, anglers cannot adjust the center of gravity of the fishing rod to a desired position. To resolve this inconvenience, the same document also discloses a balance adjustment member whose mounting position can be adjusted. However, this adjustment mechanism fastens a ring-shaped balance adjustment member to the rod with a screw, so the work is not easy. Moreover, in order to fasten it securely, the outer diameter of the rod must be above a certain level, so it cannot be applied to, for example, carp rods.

[0006] The weight 58 disclosed in Patent Document 2 is a so-called weight-shaped object. Therefore, it is easy to attach and detach regardless of the size of the rod's outer diameter, and its position can be easily adjusted. However, depending on how the rod bends, there is a risk that the weight 58 may come off the fishing rod.

[0007] The present invention was made against this background, and its purpose is to provide a fishing rod weight that can be easily attached to and detached from a fishing rod and whose position can be changed, and a fishing rod equipped therewith, which allows for easy and quick adjustment of the action or center of gravity of the fishing rod. [Means for solving the problem]

[0008] (1) The fishing rod weight according to the present invention comprises a wire that is wound around the outer surface of the fishing rod body. This wire is elastic and at least a portion of it overlaps the axial direction of the fishing rod body.

[0009] In this configuration, the fishing rod weight comprises an elastic wire. Therefore, the fishing rod weight is attached to the outer surface of the fishing rod body with a predetermined tension while being wound around it, and is also movable along the axial direction of the fishing rod body.

[0010] (2) Preferably, the wires are superimposed at multiple locations along the axial direction.

[0011] In this configuration, the wire is wrapped around the fishing rod body multiple times. Therefore, the fishing rod weight is securely positioned relative to the fishing rod body. Moreover, there is the advantage that the mass of the fishing rod weight can be easily adjusted simply by changing the number of times the wire is wrapped around it.

[0012] (3) Preferably, the winding interval of the wire is set to be larger than the outer dimensions of the wire.

[0013] In this configuration, gaps are formed between the wound wires. Therefore, it becomes easier to attach and detach the fishing rod weight to the fishing rod body. Here, the "outer dimensions of the wire" refers to the width dimension of the cross-section of the wire, that is, the dimension along the axial direction of the fishing rod body.

[0014] (4) It is preferable that the internal dimensions of the weight change gradually along the axial direction in accordance with the change in the outer diameter of the fishing rod body.

[0015] Generally, the outer shape of a fishing rod body is tapered, and the outer diameter of the fishing rod body changes gradually along the axial direction. In this invention, since the inner dimension of the weight corresponds to the change in the outer diameter of the fishing rod body, the fishing rod weight is attached to the fishing rod body more stably. Here, the "inner dimension of the weight" is the outer diameter of a virtual circle defined by the inner ridge of the fishing rod weight formed by winding the wire material.

[0016] (5) The wire is preferably made of a metal material having an outer diameter of 0.2 mm or more and 1.0 mm or less.

[0017] In this case, the mass of the fishing rod weight can be precisely adjusted to 2,000g (grams) or less. Furthermore, the process of winding the wire becomes simpler. In addition, if the wire has a circular cross-section, the structure of the fishing rod weight becomes simpler, making it easier to attach and detach it from the fishing rod.

[0018] (6) A fishing rod equipped with the aforementioned fishing rod weight may be constructed. [Effects of the Invention]

[0019] According to the present invention, the sinker for a fishing rod can be easily attached to and detached from the fishing rod body, and its position can be changed. Therefore, an angler can easily and quickly change the balance or the center of gravity position of the fishing rod.

Mode for Carrying Out the Invention

[0021] Hereinafter, preferred embodiments of the present invention will be described while appropriately referring to the drawings. It should be noted that this embodiment is merely one aspect of the fishing rod and the sinker for a fishing rod according to the present invention, and it is needless to say that the embodiment may be changed within the range not changing the gist of the present invention.

[0022] <Structure of Fishing Rod and Sinker for Fishing Rod>

[0023] FIG. 1 is an external perspective view of a fishing rod 10 according to an embodiment of the present invention.

[0024] The fishing rod 10 is a so-called telescopic rod and is typically used for carp fishing. The fishing rod 10 has a fishing rod body 17, a grip 18, and a weight 19 (corresponding to the "fishing rod weight" described in the claims). The fishing rod body 17 consists of six blanks. Each blank is referred to as the first section 11, second section 12, third section 13, fourth section 14, fifth section 15, and sixth section 16, in order from the tip. The first section 11 and the sixth section 16 are sometimes specifically referred to as the tip section and the butt section, respectively. The number of blanks constituting the fishing rod 10 is not particularly limited.

[0025] The grip 18 is located on the butt section 16. The angler operates the fishing rod 10 by gripping the grip 18. When used as a carp fishing rod, the main operations of the fishing rod 10 are casting the rig and retrieving the hooked fish. In particular, when carp fishing, it is important for the angler to be able to softly cast the baited rig to the desired point using the elasticity of the tip section 11 and the second section 12. For this reason, research has been conducted on the rigidity of the tip section 11 and its bending when external forces are applied, and the action of fishing rods has been improved in various ways.

[0026] In this embodiment, the length, butt diameter, and tip diameter of the second section 12 are set to 700 mm, 5.9 mm, and 4.2 mm, respectively, while the length, butt diameter, and tip diameter of the tip section 11 are set to 530 mm, 3.27 mm, and 1.05 mm, respectively. Thus, the external shape of each section 13 to 16 generally exhibits a predetermined taper. The length, butt diameter, and tip diameter of each section 11 to 12 are changed according to the specifications of the fishing rod.

[0027] Each section 11-16 is formed in a known manner. Typically, a resin sheet (prepreg) reinforced with so-called carbon fiber is cut into a predetermined shape and wound around a mandrel. After the prepreg is heat-treated at a predetermined temperature, the mandrel is withdrawn, and the cylindrical sections 11-17 are fired. The fishing rod 10 is formed by assembling these sections 11-16 in a serrated manner. However, each section 11-16 may be assembled in a telescopic or other jointed manner.

[0028] A key feature of this embodiment is that the weight 19 is detachably attached to the tip section 11.

[0029] Figure 2 is an enlarged perspective view of the main part of Figure 1, schematically showing the state in which the weight 19 is attached to the tip section 11. Figure 3 is a schematic cross-sectional perspective view of a part of the weight 19.

[0030] In these figures, reference numeral 20 indicates the axial direction of the fishing rod body 17, arrow 21 points to the tip side, and arrow 22 points to the butt end side.

[0031] The weight 19 is made of an elastic wire. In this embodiment, the cross-sectional shape of this wire is circular. In this embodiment, the material of the wire is stainless steel (density 7.93 g / cm³). However, the cross-sectional shape of the wire constituting the weight 19 is not limited to circular, and materials other than stainless steel, such as metals or resins, can also be used. Naturally, changing the material of the wire will also change the density of the wire.

[0032] In this embodiment, the weight 19 is formed by winding the wire into a coil shape. This coiled weight 19 is fitted onto the tip section 11 and fixed in a predetermined position. The attachment and detachment of the weight 19 will be described in detail later, but the weight 19 expands elastically in diameter and is fixed to the tip section 11 by its tensioning force.

[0033] Figure 4 is a perspective view of the weight 19 in its natural state.

[0034] In this embodiment, the specifications of the weight 19 in its natural state are as follows. Here, "natural state" refers to a state in which no external force acts on the weight 19.

[0035] The wire diameter 23 (corresponding to the "outer dimensions of the wire" as described in the claims) = 0.4 mm (however, it may be set to 0.2 mm to 1.0 mm). If the cross-sectional shape of the wire constituting the weight 19 is other than circular, the wire diameter 23 refers to the width dimension of the cross-section of the wire (i.e., the dimension along the axial direction 20).

[0036] The inner diameter 24 (corresponding to the "inner dimension of the weight" as described in the claims) is 1.0 mm to 35.0 mm. Preferably, the inner diameter 24 is set to be about 0.5 mm smaller than the outer diameter of the fishing rod body 17 at a predetermined position on the fishing rod 10 where the weight 19 is fixed. If the cross-sectional shape of the wire material constituting the weight 19 is other than circular, the inner diameter 24 refers to the diameter of the ridge line (virtual circle) that is in contact with the inner wall of the wound wire material.

[0037] The effective number of turns is 25 = 120 (however, it can be set to 1 to 240). As the wire is wound in this manner, the wire itself overlaps at least one point along the axial direction 20. That is, the wound wires are aligned along the axial direction 20.

[0038] Pitch 26 (corresponding to the "winding interval" described in the claims) = 1.0 mm. However, the pitch 26 only needs to be set to a dimension greater than or equal to the wire diameter 23.

[0039] The winding direction is not particularly limited; either left or right direction can be used.

[0040] Based on the above specifications, the weight 19 exhibits the characteristics of a coil spring, and its mass can be adjusted from approximately 0.003g to 1.000g depending on the wire diameter 23, inner diameter 24, and effective number of turns 25. However, by changing the material of the wire constituting the weight 19 and adjusting the effective number of turns, the mass of the weight 19 can be adjusted up to approximately 2.000g. The end treatment of the weight 19 may be provided with a seat winding, similar to the design of a coil spring, or it may be formed as a closed end or an open end.

[0041] In this embodiment, the inner diameter 24 of the weight 19 is constant along the axial direction 20. However, this inner diameter 24 may be designed to gradually change along the axial direction 20 in response to the change in the outer diameter of the tip section 11 (i.e., the taper). The effects of the case where the inner diameter 24 of the weight 19 changes in accordance with the taper formed in the tip section 11 will be described later.

[0042] <Instructions for using fishing rods and fishing rod weights>

[0043] The angler can attach the weight 19 to the tip section 11 of the fishing rod body 17. Specifically, the weight 19 is fitted by sliding it from the tip of the tip section 11 along the axial direction 20 toward the butt end side 22. Since the outer shape of the tip section 11 has the aforementioned taper, when the weight 19 is fitted into the tip section 11, the two are pressed together radially relative to each other. Since the wire material that makes up the weight 19 is elastic, the weight 19 deforms elastically in the radial direction, and the inner diameter 24 expands.

[0044] As a result, as shown in Figure 2, the weight 19 is wrapped around the outer surface of the tip section 11 and attached to the tip section 11 by the tension force caused by the elastic deformation. In the figure, the weight 19 is pushed towards the butt end 22, resulting in compression in the axial direction 20 and a reduction in the gap 27 between the wires. However, when the weight 19 is returned to the tip end 21, the gap 27 widens. In other words, the angler can fix the weight 19 in the desired position by sliding it relative to the tip section 11.

[0045] In this embodiment, since the weight 19 is formed in a coil spring shape by winding the wire, the wires overlap and align along the axial direction 20. Therefore, instead of fitting the weight 19 from the tip of the tip section 11, the angler can attach the weight 19 from a desired position on the fishing rod body 17 simply by inserting the fishing rod body 17 between the overlapping wires and rotating the weight 19. Consequently, the weight 19 can also be attached to the second section 12, the third section 13, etc., in addition to the tip section 11. In other words, if the fishing rod 10 is provided with a fishing line guide, the fishing line guide may get in the way and prevent the weight 19 from sliding to the desired position if the angler tries to fit the weight 19 from the tip of the tip section 11. However, even in such a case, the weight 19 according to this embodiment can be easily attached to the fishing rod body 17 while avoiding the fishing line guide.

[0046] By attaching a weight 19 to the tip section 11, the way the tip section 11 and the second section 12 bend when an external force is applied, and consequently the action of the fishing rod 10, is changed. Moreover, the angler can easily change the position of the weight 19 relative to the tip section 11, and the weight 19 can also be easily attached and detached. Therefore, the angler can easily and quickly change the action or center of gravity of the fishing rod 10, and for example, in carp fishing, the casting of the rig can be done easily and accurately.

[0047] Since the weight 19 can be attached to the second section 12 and other parts of the fishing rod body 17 besides the tip section 11, the angler can easily achieve the desired action of the fishing rod 10 during actual fishing by changing the position of the weight 19. Furthermore, since the weight 19 is formed by winding the aforementioned wire material, the weight 19 easily deforms in accordance with the deformation of the fishing rod body 17. As a result, the angler does not feel any discomfort when landing a hooked fish.

[0048] Incidentally, a "cello line" is generally formed on the molded fishing rod body 17. This cello line is a molding line created by the molding tape (the tape used to tighten the prepreg wound around the mandrel). Since the wire material that makes up the weight 19 is wound around it, the angler can align the winding direction with the cello line formed on the fishing rod body 17. For example, by aligning the winding direction of the wire material with the cello line, the weight 19 can be attached to the fishing rod body 17 more easily while rotating it, and by setting the winding direction to go against the cello line, the weight 19 can be held more firmly to the fishing rod body 17. Therefore, when the fishing rod 10 is configured for vigorous casting, such as a surfcasting rod, the weight 19 is prevented from coming off during operation of the fishing rod body 17.

[0049] The effective number of turns of the wire constituting the weight 19 is not particularly limited, as long as it is one or more. In this embodiment, as shown in Figure 2, the wire is superimposed at multiple locations along the axial direction 20, so that the wire is wound around the tip section 11 in multiple layers. Therefore, the weight 19 is reliably positioned relative to the tip section 11.

[0050] In this embodiment, as shown in Figure 4, the pitch 26 (winding interval) of the wires constituting the weight 19 is set to be larger than the wire diameter 23, and a gap 27 is formed between the wound wires. Therefore, there is an advantage in that the work of attaching and detaching the weight 19 to the fishing rod body 17 becomes even easier.

[0051] In this embodiment, the inner diameter 24 of the weight 19 may gradually change along the axial direction 20 in accordance with the change in the outer diameter of the tip section 11. In that case, the weight 19 will be attached to the tip section 11 more stably. The same applies when it is attached to sections 12 to 16 other than the tip section 11.

[0052] In this embodiment, the weight 19 is made of a metal material with a wire diameter of 0.2 mm or more and 1.0 mm or less, so the mass of the weight 19 can be precisely adjusted to 2,000 g or less. Moreover, the process of winding the wire is simplified.

[0053] <Modified examples of embodiments>

[0054] Figure 5 is an enlarged perspective view of the main part of the fishing rod 30 according to the first modified example of this embodiment.

[0055] The difference between the fishing rod 30 in this modified example and the fishing rod 10 lies in the shape of the weight 31. Specifically, while the weight 19 attached to the fishing rod 10 (see Figure 2) was formed by winding the wire material in multiple coils, this weight 31 is formed in a ring shape by winding the wire material only once. The other components are the same as in the above embodiment.

[0056] Figure 6 is an enlarged cross-sectional perspective view of a fishing rod 40 according to a second modified example of this embodiment.

[0057] The difference between the fishing rod 40 in this modified example and the fishing rod 10 lies in the cross-sectional shape of the wire that makes up the weight 41. That is, while the weight 19 is made of wire with a circular cross-section, the wire that makes up the weight 41 has a rectangular cross-sectional shape. In this case, the wire diameter 23 of the wire that makes up the weight 41 is the dimension along the axial direction 20 of the cross-section of the wire.

[0058] In this modified example, the weight 41 has a flat surface at the contact point with the first joint 11. Therefore, the weight 41 contacts the first joint 11 over a larger area than the contact area between the weight 19 and the first joint 11, resulting in a more stable attachment to the first joint 11. Moreover, since the cross-sectional area of ​​the wire constituting the weight 41 is rectangular, it is easier to design a larger cross-sectional area compared to a circular shape. As a result, it becomes possible to miniaturize the weight when designing a weight of a predetermined mass. [Explanation of symbols]
