Abstract

Fixation strength between a mounting leg and a rod body depends on the presence of a thread wound layer and an adhesive agent layer. When a smoothly curved slope is formed on the mounting layer as in conventional mounting legs, frictional resistance between the slope and a wound thread is relatively small, and in addition, after the fixation, a wedge effect acts to split between the adhesive agent layer and the rod body. As a consequence, if a fishing rod is used under severe conditions, the mounting leg is displaced. The flat slope (13) at the tiptoe (8) of the mounting leg (7) is formed such that, in a side view, two edge ridgelines (17, 19) defining both right and left outlines of the flat slope extend linearly from the upper surface of the mounting leg (7) to the outer peripheral surface (5) of the rod body (3) and merge at the end of the mounting leg at which end the mounting leg reaches the outer peripheral surface (5). The movement of the wound thread (21) is stopped by an edge effect.

Fishing rod accessories

Technical field

[0001] The present invention relates to a fishing rod accessory having a mounting foot fixed to the outer peripheral surface of the rod body by a rod thread.

For example, the present invention relates to accessories such as a yarn introduction ring, a reel sheet, and a hook ring.

Background art

[0002] The conventional thread guide ring 101 and the above-mentioned accessories shown in FIG. 10 have a smooth upper surface, usually called a foot shaving portion, at the toe 104 of the mounting foot 103 (that is, the ruling side). It is used after the inclined surface 105 is formed by cutting. At that time, the tip 104 of the mounting foot 103 has a sharp wedge shape.

When fixing the mounting foot 103 to the outer peripheral surface 109 of the housing 107, first, the thread 111 is wound around the outer peripheral surface 109 of the housing 107 to form the thread layer 113, and then the foot of the mounting foot 103 is formed. 104 is pressed against the outer peripheral surface 109 so as to come into contact with the end surface of the thread layer 113, and the thread 111 is wound around the outer surface 109 of the mounting foot 103 and the housing 107, and finally, an adhesive is applied and solidified. Fix the thread layer 113, the casing 107 and the mounting foot 103.

Problems to be solved by the invention

[0004] Fig. 6-101 is a side view of a conventional product. This figure will be described as an example. In the case of the conventional product, the fixing strength between the mounting foot 103 and the frame body 107 depends on the presence of the thread layer 113 and the adhesive layers 115 and 117. Therefore, when the smoothly curved inclined surface 105 is formed as described above, the frictional resistance between the inclined surface 105 and the kite string 111 is conversely reduced. Moreover, the following problems become apparent when fishing rods are used under severe conditions.

[0005] For example, if stress is applied to the mounting foot 103 in a direction that moves forward or backward relative to the axial direction, as shown in Fig. 6 Conventional product 101 (2) Stress load diagram, The agent layer 117 does not endure, and the bottom surface force of the mounting foot 103 is peeled off from the outer peripheral surface 109 of the housing 107 or the mounting foot 103 becomes loose. In this state, further stress is applied in the forward direction. When loaded, the wedge of the foot 104 acts to peel off the adhesive layer, so that the mounting foot 103 can easily advance and tear the front adhesive layer 115, and finally the thread layer 113 and It penetrates through the front side adhesive layer 115, that is, breaks through and gets exposed. At that point, the life of the fishing rod will be shortened due to the water entering it and corrosion of the exposed metal.

Further, when torsional stress is further applied in the lateral direction, as shown in the column of conventional product 101 in FIG. 7, the cross section of the foot cut portion is substantially bowl-shaped, so the adhesive layer is peeled off in the same manner. Work easily and shifts in the horizontal direction. If the deviation is large, it can no longer be used.

Furthermore, as shown in Fig. 6-101 (3) Bending load diagram, the step 118 defined by the tip 104, which is the farthest portion of the mounting foot 103, and the outer peripheral surface 109 of the housing 107, is the most bent. It is a place that is weak to the load, and cracks are easily generated in the front-side resin layer 115 when subjected to repeated bending loads there. If the crack reaches the metal material constituting the mounting foot 103, the life of the fishing rod will be shortened due to water entering or corrosion of the exposed metal material. In addition, the conventional product has a problem that the area of the foot cut is large, so frictional heat is generated when cutting is performed, and the surface of the material is altered by heat generation, resulting in a decrease in corrosion resistance.

Furthermore, when the inclined surface 105 was formed large, the inclined surface reached the crack 12, and there were cases where the mounting foot 7 was separated into the left and right and could not be used.

[0006] In Patent Document 1 described above, it is possible to quickly wind the kite by providing the thin end portion of the inclined surface with the thin end portion, but even if the tip portion is provided, the fishing rod During use, the above mentioned problems can occur as well.

[0007] Therefore, an object of the present invention is to provide an accessory having a mounting foot on which an inclined surface having a devised shape can be effectively avoided.

Means for solving the problem

[0008] In order to solve the above problems, as a result of intensive studies on the shape of the inclined surface, a shape capable of simultaneously solving a plurality of problems that have been recognized in the past as well as the above-described problems related to the fixing strength is devised. This is described below.

The invention of claim 1 is the attachment of a fishing rod having an attachment foot fixed to the outer peripheral surface of the rod body by the thread, and an inclined surface is formed at the tip of the attachment foot.

BEST MODE FOR CARRYING OUT THE INVENTION

[0016] A yarn introduction ring 1 as an example of an attachment for a fishing rod according to a first embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the yarn introduction ring is attached and fixed to the outer peripheral surface 5 of the housing 3. The above-described yarn introduction ring 1 is integrally formed from one metal flat plate material. First, it is punched into a predetermined frame shape by pressing, and further bent to form a predetermined three-dimensional shape.

[0017] In the yarn introduction ring 1, mounting feet 7 and 9 are attached and fixed to the outer peripheral surface 5 of the casing 3 in series in the axis direction. Each of the mounting feet 7 and 9 has a shape resembling a tapered tongue when viewed from above. On the left and right side surfaces, the punched surface is exposed as it is, and has a steep wall 11 that roughly corresponds to the thickness of the plate. Incidentally, reference numeral 12 indicates a crack, and this crack 12 is caused by the fact that a single flat plate member made of metal is integrally formed without waste.

Inclined surfaces 13 and 15 are formed on the feet 8 and 10 of the mounting feet 7 and 9, respectively. Inclined surface 1 Since the shape characteristics of 3 and 15 are common, the inclined surface 13 of the mounting foot 7 will be described below as a representative.

The inclined surface 13 is formed in a substantially flat shape, and the inclined surface 13 is formed by cutting using a tool. The inclined surface 13 is substantially triangular when viewed from above.

Reference numerals 17 and 19 denote two edge ridge lines, which define the contours on the left and right sides of the inclined surface 13 (relative to the axial direction).

These two edge ridge lines 17 and 19 extend substantially downward in the left-right direction toward the outer peripheral surface 5 of the housing 3 at the top surface force of the mounting foot 7, and merge at the tip that reaches the outer peripheral surface 5.

FIG. 2 is a side view of the state where the mounting foot 7 is placed on the outer peripheral surface 5 of the housing 3 as viewed from the side, that is, from the lateral direction. As shown in this figure, the edge ridge line 17 extends linearly, and the bending force also forms the upper contour of the mounting foot 7. That is, steep wall surfaces 11 are left as they are on the left and right sides of the mounting foot 7.

The inclination angle (Θ) of the inclined surface 13 is set to an arbitrary value in the range of 10 to 30 °, and the standard force for setting the conventional cutting part is also set to a steep slope of force.

FIG. 3 is a cross-sectional view of the mounting foot 7 placed on the outer peripheral surface 5 of the housing 3 as seen from the axial direction. As shown in this figure, the edge ridge lines 17 and 19 exist at the left and right ends of the inclined slope 13 as edge ridge lines facing outward.

[0020] Fig. 4 is a diagram showing the fixed state viewed from the lateral direction, and Fig. 5 is a diagram showing the fixed state viewed from the axial direction.

The mounting foot 7 is placed on the outer peripheral surface 5 of the casing 3, the thread 21 is wound to form the thread layer 23, and the adhesive layers 25 and 27 are formed by applying and solidifying the adhesive. Finally, the mounting foot 7 is fixed to the outer peripheral surface 5 of the housing 3.

The adhesive layer is formed not only so that the front side adhesive layer 25 covers the upper thread layer 23 but also the back side adhesive layer 27 is formed between the bottom surface of the mounting foot 7 and the outer peripheral surface 5 of the casing 3. It is formed by intrusion and solidification in the fluid stage.

[0021] In the following, the effect produced by the attachment foot 7 provided in the yarn introduction ring 1 will be described.

(1) Further improvement of fixing strength As shown in Fig. 4 and Fig. 5, when the kite string 21 is hooked on both the inclined surface 13 and the frame 3 of the mounting foot 7, the kite string 21 is placed on that surface on the tilted surface 13. Although it exists in a state, it is bent steeply at the edge ridgelines 17 and 19 toward the wall surface 11 and reaches the outer peripheral surface 5 of the housing 3. At that time, the two edge ridges 17 and 19 are in a frictionally coupled state with respect to the kite thread 21, and the shifting of the attachment foot 7 in the front-rear direction with respect to the kite thread layer 23 is prevented.

Also, as shown in Fig. 4.5, the inclination angle (Θ) of the inclined surface 13 is large and the steep wall surface 11 remains on the side surface of the mounting foot 7, that is, the tip of the mounting foot 7. Is not a sharp wedge shape, so even if stress is applied, the front adhesive layer 25 is not easily torn.

Furthermore, as shown in FIGS. 4 and 5, the adhesive layers 25 and 27 are formed by applying and solidifying a fluid adhesive, and the outer surfaces of the wall surface 11 of the mounting foot 7 and the casing 3 are solidified. The step difference of the side step portion 28 defined by the surface 5 and the tip step portion 30 defined by the inclined surface 13 of the mounting foot 7 and the outer peripheral surface 5 of the housing 3 is larger than that of the conventional product—101 in FIG. Therefore, when the adhesive is applied, large reservoir portions 29 and 31 of the adhesive are formed so as to fill the respective step portions 28 and 30 by surface tension.

In particular, since the level difference of the side step portion 28 is large, the side adhesive reservoir portion 29 is greatly formed. Since the lateral adhesive reservoir 29 is formed on both the left and right sides of the mounting foot 7, even if a lateral force torsional stress is applied to the mounting foot 7, the left and right lateral adhesive reservoir 29 is said to be a bank. Exists and prevents lateral displacement of the mounting foot 7.

As a result of the combined effects described above, even when stress is applied to the yarn introduction ring from the front and rear and the lateral direction when the fishing rod is used, as shown in FIGS. 6 and 7, the product of the present invention (ie the yarn introduction ring 1) With regard to, the mounting foot 7 is stably fixed to the outer peripheral surface 3 of the housing 3 due to the high fixing strength, and it is possible to effectively prevent the occurrence of misalignment and the like.

[0023] (2) Prevention of occurrence of cracks in adhesive layer

As shown in FIG. 4, the step of the front step portion 30 (that is, the inclination angle (Θ) of the inclined surface 13) is larger than that of the conventional product 101. A front adhesive reservoir 31 having a large adhesive is formed so as to fill the stepped portion 30. The front stepped portion 30 is defined by the farthest portion of the mounting foot 7 and the outer peripheral surface 5 of the housing 3. In this part, the force that is the weakest part for repeated bending load is a large (that is, thick) tip adhesive reservoir 31 formed thereon, so even if it is subjected to repeated bending load, As shown in Fig. 6 Invention 1 (1) (3) Bending load diagram, with respect to the product of the present invention, cracks hardly occur in the tip adhesive reservoir 31 (that is, the front adhesive layer 25). There is almost no possibility of penetration.

[0024] (3) Workability during brazing

As shown in Fig. 1, the foot 8 of the mounting foot 7 has a wedge shape.

If the inclined surface 13 is steep when attaching the thread guide ring 1 to the outer peripheral surface 5 with the heel thread 21 from the foot 8, the heel thread 21 is placed on the inclined surface 13, especially for beginners with poor control of the wrapping pressure. When applied, there was a problem that the silk thread 21 was likely to slide down the slope. However, in the case of the present invention, the corners of the two edge ridge lines 17 and 19 bite into the kite thread 21 and, so to speak, are frictionally coupled, so that the kite string 21 is prevented from slipping, and even beginners can wrap the kite string 21 smoothly. it can. In particular, if the inclination angle (Θ) of the inclined surface 13 is increased, the length of the inclined surface 13 in the axial direction is shortened, so that the number of times of the winding 21 on the inclined surface 13 is reduced, and the The possibility of sliding down is lower.

Further, since the mounting foot 7 is not wedge-shaped, there is an advantage that the risk of damaging the operator's hand and the housing 3 is reduced.

[0025] (4) Workability when forming inclined surfaces

In the case of the present invention, as shown in FIG. 1, since the wall surface 11 remains even if the inclined surface 13 is formed on the mounting foot 7, the cutting area is smaller than that of the conventional product 101 shown in FIGS. In particular, when the inclination angle (Θ) of the inclined surface 13 is set to be steep, the cutting area becomes smaller. Therefore, the heating time is shortened and, naturally, material deterioration due to heat generated by cutting is suppressed compared to the conventional product 101.

Further, since the inclined surface 13 is simply formed into a single steep flat shape, it does not reach the crack 12 shown in FIG. By the way, when the inclined surface 13 reaches the crack 12, the mounting foot 7 is divided into left and right, and there may be cases where it cannot be used.

[0026] FIG. 8 shows a yarn introduction ring 33 as an example of a fishing rod accessory according to the second embodiment of the present invention. Therefore, it explains.

An anti-slip embossing portion 37 is formed on the upper surface of the attachment foot 35 of the yarn introduction ring 33 for the purpose of a spike effect. The inclined surface 39 is formed by cutting the embossed portion 37. The shape of the inclined surface 39 is the same as that of the inclined surface 13 according to the first embodiment.

The inclined surface 39 is formed with a steep slope like the inclined surface 13, and the cutting area of the embossing force feeding portion 37 is minimized.

The embodiment of the present invention has been described above, but the specific configuration of the present invention is not limited to the above-described embodiment, and there are design changes within a scope that does not depart from the gist of the present invention. Are also included in the present invention.

For example, in the above-described embodiment, there is a single mounting foot for the side support legs, and the tip ends of the pair of side support legs shift from the left and right sides to the mounting legs. A pair of mounting feet may be provided, and each mounting foot may be in contact with the outer surfaces on the left and right sides of the housing. For example, even if the mounting legs 41, 43, 45 having the shape as shown in FIG. 9 are provided, if the inclined surfaces 42, 44, 46 are formed, they are included in the scope of the present invention.

[0028] At present, most of the accessories for fishing rods such as the frame for the yarn introduction ring, the reel seat, and the hook ring are integrally formed by a metal plate frame force press carriage or the like. Since the present invention is characterized by its shape, it may be based on other manufacturing methods such as forging, forging, just wax, MIM, etc., and each of the ring holding portions constituting the yarn introduction ring frame, etc. The part may be formed by two or more members.

In any case, with the exception of the claimed shape and the like, any conventional or future shape or production can be arbitrarily combined.

Industrial applicability

[0029] According to the fishing rod attachment according to the present invention, the fixing strength of the mounting foot and the frame 'generation of cracks in the adhesive layer' workability during brazing of the bobbin thread 'work when forming the inclined surface It is an epoch-making solution that solves multiple issues such as gender at the same time in a high balance, and has succeeded in answering the comprehensive demands of demanding users.
