Description

Technical Field

[0001] The present invention relates to a tension applying device for applying tension to fishing line wound around a reel. More specifically, the present invention relates to a tension applying device that can be adjusted by accurately measuring the magnitude of the tension applied to the fishing line.

Background Art

[0002] Fishing line used when fishing for large fish is generally tightly wound around a reel under tension. This is because when the fish is hooked on the fishing rod, a large tension is applied to the fishing line. If it is not tightly wound around the reel in advance, the fishing line on the outer peripheral side of the reel will bite into the fishing line on the inner peripheral side. When biting occurs, the fishing line may break or the fishing line may not be smoothly paid out from the reel.

[0003] Here, applying tension to the fishing line and winding it around the reel can be done by manually pulling the fishing line, etc., but the work is complicated. For this reason, a tension applying device for applying tension to the fishing line has also been devised.

[0004] For example, the fishing line tension applying device of Patent Document 1 rotatably supports a single tension roller or a pair of tension rollers on a base, and by winding the fishing line around this tension roller a plurality of times, tension is applied to the fishing line paid out therefrom due to the friction between the fishing line and the tension roller and the rotational resistance of the tension roller. The fishing line is pulled out from a bobbin, passes through the tension roller, and after tension is applied, it is wound around the reel.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 7-255333 [Summary of the Invention] [Problems to be Solved by the Invention]

[0006] However, in the fishing line tension applying device of Patent Document 1, the specific magnitude and numerical value of the tension applied to the fishing line were unknown. For this reason, based on the experience and intuition of individuals fishing, the rotational resistance of the tension roller was appropriately varied and adjusted so as to suit the type of fish and the situation, etc., to adjust the tension applied to the fishing line. However, adjusting the tension of the fishing line in this way requires skill and experience, and delicate adjustment is also difficult.

[0007] Therefore, the problem to be solved by the present invention is, in a tension applying device for applying tension to a fishing line, to make it possible to accurately measure the magnitude of the tension and facilitate the adjustment of the tension. [Means for Solving the Problems]

[0008] In order to solve the above problems, the fishing line tension applying device according to the invention includes a base on the surface of which a fishing line is paid out from an upstream bobbin toward a downstream reel, a pair of tension rollers rotatably supported on the upstream side of the base surface with respect to the fishing line pay-out direction, and a fishing line tension meter provided on the downstream side of the base surface with respect to the fishing line pay-out direction. And the fishing line is wound around a pair of tension rollers alternately a plurality of times, so that tension is applied on the downstream side of the tension rollers, and the tension applied to the fishing line is measured by the tension meter.

[0009] Alternatively, in order to solve the above problems, the fishing line tension applying device according to the invention includes a base on the surface of which the fishing line is paid out from the upstream bobbin toward the downstream reel, a single tension roller rotatably supported on the upstream side of the base surface with respect to the pay-out direction of the fishing line, and a fishing line tension meter provided on the downstream side of the base surface with respect to the pay-out direction of the fishing line. The fishing line is wound around the tension roller a plurality of times, so that tension is applied on the downstream side of the tension roller, and the tension applied to the fishing line is measured by the tension meter.

[0010] By configuring in this way, since the magnitude of the tension applied to the fishing line can be accurately measured by the tension meter, it becomes extremely easy to adjust the tension according to the type of fish and the situation.

[0011] In the fishing line tension applying device according to the invention, it is preferable to adopt a configuration in which the tension meter has a slider, a slider roller rotatably supported by the slider and around which the fishing line is hung in a U-shape, and a spring that biases the slider in a direction opposite to the force applied from the tension roller by the fishing line, and the tension of the fishing line can be measured according to the position of the slider at which the force applied from the tension roller by the fishing line and the biasing force of the spring are balanced.

[0012] By configuring in this way, the tension meter can have a simple structure. Since the tension of the fishing line is proportional to the contraction length of the spring, the magnitude and numerical value of the tension can be easily read by marking a scale along the expansion and contraction direction of the spring.

[0013] In the fishing line tension applying device according to the invention, it is preferable to further include a slider guide that guides the slider of the tension meter in a direction that coincides with the expansion and contraction direction of the spring, and this slider guide is made of metal.

[0014] With such a configuration, since the slider guide is made of metal, it is wear-resistant, and because of its good sliding property, the guiding of the slider by the slider guide is performed smoothly.

[0015] In the fishing line tension applying device according to the invention, it further includes a clamp that can fix the base to a fixed object. The clamp can be attached to the back surface of the base in a plurality of attachment directions, and thus, it is preferable to adopt a configuration in which the fixing direction of the base with respect to the fixed object is variable.

[0016] With such a configuration, since the degree of freedom in the fixing direction of the base with respect to the fixed object increases, the fixing direction of the base can be changed according to the dominant hand of the person performing the work, the state of the working space, and the shape of the fixed object, and the work of applying tension to the fishing line becomes even easier.

[0017] In the fishing line tension applying device according to the invention, an inlet guide roller that is rotatably supported upstream of the tension roller of the base with respect to the feeding direction of the fishing line and guides the fishing line, and an outlet guide roller that is rotatably supported downstream of the tension meter of the base with respect to the feeding direction of the fishing line and guides the fishing line are further provided. It is preferable to adopt a configuration in which these inlet guide roller and outlet guide roller have a fishing line retaining cover.

[0018] With such a configuration, when viewed from the feeding direction of the fishing line, the upstream side is supported by the inlet guide roller and the downstream side is supported by the outlet guide roller, respectively. Therefore, the feeding of the fishing line to the tension roller and the drawing out from the tension meter are performed smoothly. Also, since a retaining cover is attached to both guide rollers, it is possible to prevent the fishing line from coming off the guide roller.

[0019] In the fishing line tension applying device according to the invention, it is preferable to adopt a configuration in which the retaining cover of the inlet guide roller is rotatable around the rotation axis of the inlet guide roller.

[0020] By configuring in this way, no matter what direction the fixing direction of the base to the fixed object is, by appropriately rotating the retaining cover, the fishing line can be guided while being retained by the inlet guide roller, so that the feeding of the fishing line to the tension roller is performed more smoothly.

[0021] In the fishing line tension applying device according to the invention, it is preferable to adopt a configuration in which a pair of intermediate guide rollers that are rotatably supported in parallel on the base on the downstream side of the tension roller and on the upstream side of the tension meter with respect to the feeding direction of the fishing line are further provided to guide the fishing line.

[0022] By configuring in this way, since the fishing line is supported by the intermediate guide rollers between the tension roller and the tension meter, the feeding of the fishing line from the tension roller and the feeding of the fishing line to the tension meter are performed smoothly. Since the intermediate guide rollers are parallel, the load applied to them from the fishing line is dispersed, and breakage and the like are suppressed.

[0023] In the fishing line tension applying device according to the invention, it is preferable to adopt a configuration in which the base has an annular collar on the outer periphery of the support portion of each roller, and when viewed from the surface of the base, the bottom end surface of each roller is at a position lower than the collar.

[0024] By configuring in this way, the collar serves as a barrier to prevent the fishing line from being caught on the back side of the bottom end surface of each roller, and the feeding of the fishing line becomes even easier.

[0025] In the fishing line tension applying device according to the invention, on the body of the tension roller, a large-diameter portion that separates between small-diameter portions adjacent to the small-diameter portion for winding the fishing line are alternately formed in the axial direction of the tension roller, and it is preferable to adopt a configuration in which the small-diameter portion is made of rubber.

[0026] With such a configuration, since rubber has a large coefficient of friction, it becomes easy to apply tension to the fishing line, and since rubber has high heat insulation properties, it is possible to prevent the tension roller from being heated by the heat of the fishing line.

[0027] In the fishing line tension applying device according to the invention, it is preferable to adopt a configuration in which the body of the tension roller is decomposable into a small-diameter portion and a large-diameter portion.

[0028] With such a configuration, even when the small-diameter portion that rubs against the fishing line wears out, it is possible to replace only the small-diameter portion instead of replacing the entire tension roller, so that the replacement cost can be suppressed.

Effect of the Invention

[0029] Since the fishing line tension applying device according to the invention is configured as described above, it has become possible to accurately measure the magnitude of the tension and facilitate the adjustment of the tension.

Best Mode for Carrying Out the Invention

[0031] Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 5, the fishing line tension applying device 10 is a device for applying tension to the fishing line L wound from the bobbin B to the reel R as shown in FIG. 7. At that time, the magnitude of the tension can be accurately measured as a numerical value, and the accurate adjustment of the tension of the fishing line L is facilitated by the feedback of the numerical value.

[0032] As shown in FIGS. 1 to 5, the fishing line tension applying device 10 mainly includes a base 11, a pair of tension rollers 12 and a tension meter 13 supported on the surface of the base 11, and a clamp 14 attached to the back surface of the base 11. In addition, the fishing line tension applying device 10 includes an inlet guide roller 15, an outlet guide roller 16, and an intermediate guide roller 17 supported on the surface of the base 11 as components.

[0033] As shown in FIGS. 1 to 5, the base 11 is a table having a substantially square shape in plan view, and its front and back surfaces are substantially flat. On the surface of the base 11, the fishing line L passes across the base 11 (in the vertical direction in FIG. 1) from the upstream bobbin B toward the downstream reel R. Hanging holes 11a are provided at the edges of the base 11. Connecting a carabiner here, etc., improves the convenience of carrying.

[0034] As shown in FIGS. 1 to 3, the substantially cylindrical tension roller 12 is rotatably supported on the surface of the base 11. The pair of tension rollers 12 are arranged in parallel in a direction orthogonal to the direction in which the fishing line L crosses the base 11 (the left - right direction in FIG. 1). The fishing line L is alternately wound around the tension rollers 12 a plurality of times so that tension is applied to the fishing line L. As shown in Fig. 3, there is a height difference between a pair of tension rollers 12, and the fishing line L wound therebetween is inclined in the height direction (axial direction) of the tension roller 12.

[0035] Both axial ends of the tension roller 12 are flanges 12a, and the portion between the pair of flanges 12a is the body portion. The body portion is composed of small-diameter portions 12b and large-diameter portions 12c that are alternately arranged in the axial direction, and the fishing line L is wound around each small-diameter portion 12b. The small-diameter portion 12b is made of rubber, has high heat insulation, and has a large friction with the fishing line L. A knob 12d is attached to the top end face of the tension roller 12. By rotating the knob 12d in the forward and reverse directions, the rotational resistance of the tension roller 12 can be adjusted.

[0036] Here, as shown in Fig. 6, the tension roller 12 can be disassembled. As shown in the figure, the small-diameter portion 12b and the large-diameter portion 12c constituting the body portion are each composed of a small-diameter disc-shaped member and a large-diameter disc-shaped member. These are alternately overlapped and sandwiched by the flange 12a, and are integrated by a bolt 12e and a cap nut 12f that are locked to prevent rotation around the base 11. Due to such a configuration, when the small-diameter portion 12b that is likely to be rubbed and worn against the fishing line L is worn to a certain extent, the tension roller 12 can be disassembled and only the small-diameter portion 12b can be replaced. A spring 12g is externally mounted on the bolt 12e. By rotating the knob 12d in the tightening direction against the biasing force of the spring 12g, the rotational resistance of the tension roller 12 increases (the assembly of the flange 12a, the small-diameter portion 12b, and the large-diameter portion 12c is pressed against the base 11 side by the spring 12g). As such a mechanism, a mechanism similar to the drag adjustment mechanism in a reel is used.

[0037] As shown in FIGS. 1 to 3, on the base 11, a tension meter 13 is provided on the downstream side of the tension roller 12 with respect to the payout direction of the fishing line L. The fishing line L to which tension is applied by the tension roller 12 has its specific magnitude and numerical value of the tension measured by this tension meter 13. By obtaining the feedback of the numerical value and appropriately varying the rotational resistance of the tension roller 12, etc. by rotating the knob 12d, etc., the magnitude of the tension applied to the fishing line L can be accurately adjusted.

[0038] As shown in the drawing, the tension meter 13 is embedded and integrated in a horizontally long opening provided in the base 11. The tension meter 13 has a block-shaped slider 13a that is slidable in both longitudinal directions of the opening of the base 11, and a spring 13b that biases the slider 13a in one longitudinal direction (right direction in FIG. 1) of the opening of the base 11. A metal slider guide 13c as a frame body is fitted into a half portion (right half portion in FIG. 1) of the opening of the base 11, and the slider 13a is guided by the slider guide 13c so as to be able to slide smoothly. A half portion (left half portion in FIG. 1) of the opening of the base 11 is closed by a lid 13d. As a result, half of the spring 13b is hidden.

[0039] A drum-shaped slider roller 13e is rotatably supported on the slider 13a, and the fishing line L to which tension is applied after passing through the tension roller 12 is hung in a U-shape around its body portion. As a result, due to the tension of the fishing line L, a force is added to the slider 13a to slide against the biasing force of the spring 13b (to the left direction in FIG. 1). The slider 13a stops at a position where the repulsive force (proportional to the contraction length) accompanying the contraction of the spring 13b and the force added from the fishing line L to the slider 13a are balanced. On the base beside the slider 13a, a scale 13f is provided. By reading the scale 13f that coincides with the arrow attached to the slider 13a at the stop position of the slider 13a, the tension of the fishing line L can be measured.

[0040] As shown in FIGS. 1 to 3, on the surface of the base 11, a drum-shaped inlet guide roller 15 is rotatably supported upstream (the lower end in FIG. 1) of the tension roller 12 with respect to the feeding direction of the fishing line L. The inlet guide roller 15 is attached to the tip of the tower 11b protruding from the surface of the base 11. The fishing line L fed out from the bobbin B is wound around the body of the inlet guide roller 15 and guided so as to be smoothly fed into the tension roller 12. As shown in FIG. 2, since the height of the inlet guide roller 15 is substantially equal to the height of the uppermost small-diameter portion 12b of the tension roller 12, the fishing line L is fed from the inlet guide roller 15 to the uppermost small-diameter portion 12b of the tension roller 12.

[0041] The inlet guide roller 15 is attached with a U-shaped retaining cover 15a in side view. Since the wall surface of the retaining cover 15a faces the body of the inlet guide roller 15, the fishing line L is prevented from coming off the body of the inlet guide roller 15. This retaining cover 15a is rotatable around the axis of the inlet guide roller 15. Therefore, by appropriately rotating the retaining cover 15a, the fishing line L can be introduced into the inlet guide roller 15 from an arbitrary direction.

[0042] Similarly, as shown in FIGS. 1 to 3, on the surface of the base 11, a drum-shaped outlet guide roller 16 is rotatably supported downstream (the upper end in FIG. 1) of the tension meter 13 with respect to the feeding direction of the fishing line L. Unlike the inlet guide roller 15, the outlet guide roller 16 is directly attached to the base 11 without passing through the tower 11b. The body of the outgoing-side guide roller 16 is wound with the fishing line L that has passed through the tension roller 12 and the tension meter 13, and guides it so that it is smoothly fed into the reel R. The height of the outgoing-side guide roller 16 is substantially equal to the height of the lowermost small-diameter portion 12b of the tension roller 12 (and the height of the slider roller 13e of the tension meter 13 and the intermediate guide roller 17 described later), so the fishing line L is fed from the lowermost small-diameter portion 12b of the tension roller 12 to the outgoing-side guide roller 16.

[0043] The outgoing-side guide roller 16 is attached with a U-shaped retaining cover 16a in a side view. Since the wall surface of the retaining cover 16a faces the body of the outgoing-side guide roller 16, it is prevented that the fishing line L comes off from the body of the outgoing-side guide roller 16. Unlike the case of the incoming-side guide roller 15, the retaining cover 16a is fixed to be non-rotatable around the axis of the outgoing-side guide roller 16.

[0044] As shown in FIGS. 1 to 3, on the surface of the base 11, an intermediate guide roller 17 is rotatably supported on the downstream side of the tension roller 12 and on the upstream side of the tension meter 13 with respect to the feeding direction of the fishing line L. The drum-shaped intermediate guide roller 17 guides the fishing line L between the tension roller 12 and the tension meter 13 so that the fishing line L that has passed through the tension roller 12 can be smoothly fed into the tension meter 13. For the intermediate guide roller 17, two rollers are arranged in parallel with respect to the feeding direction of the fishing line L. Therefore, the load applied to the intermediate guide roller 17 from the fishing line L wound around its body and the load locally applied to the fishing line L from the intermediate guide roller 17 are dispersed.

[0045] As shown in FIGS. 1 to 3, a ring-shaped collar 11c protrudes from the surface of the base 11 so as to surround the portions supporting the tension roller 12, the outgoing-side guide roller 16, and the intermediate guide roller 17, respectively. Also, a ring-shaped color protrudes around the slider roller 13e on the slider 13a of the tension meter 13 as well. As shown in FIGS. 2 and 3, the height of these colors 11c is higher than the bottom end surfaces of various rollers. Therefore, the fishing line L wound around the body portions of various rollers is prevented from accidentally entering the back side of the bottom end surface by the color 11c serving as a barrier.

[0046] As shown in FIGS. 2 to 5, the clamp 14 is attached to the back surface of the base 11. By fixing the base 11 to a fixing object D such as a desk via the clamp 14, the operation of applying tension to the fishing line L can be performed smoothly. Here, as shown in FIGS. 4 and 5, the attachment direction of the clamp 14 to the back surface of the base 11 is variable. Therefore, the degree of freedom in the fixing direction of the base 11 with respect to the fixing object D is improved.

[0047] As shown in FIGS. 2 to 5, the clamp 14 has a U-shape in a front view, and the fixing object D can be fixed by sandwiching it between the opposing jaws 14b and the push ring 14a. The push ring 14a is fixed to the tip of the screw shaft 14e, and this screw shaft 14e passes through the tip of the arm 14c extending from the jaw 14b. The screw shaft 14e is attached with a lever 14d, and by rotating this lever 14d, the screw shaft 14e can be screw-fed in the advancing and retreating directions, and the push ring 14a at its tip can be moved closer to and away from the jaw 14b.

[0048] A disk-shaped boss 14f is continuously provided on the jaw 14b, and concavities and convexities arranged in parallel in the circumferential direction are formed on the opposing surface of the boss 14f to the back surface of the base 11. At the attachment location of the boss 14f on the back surface of the base 11, corresponding unevenness is formed in parallel in the circumferential direction, so that the clamp 14 can be attached to the back surface of the base 11 at any angle where the unevenness fits together. In that state, by tightening the handle nut 11d, the clamp 14 can be fixed to the base 11 as shown in FIGS. 4 and 5.

[0049] The configuration of the fishing line tension applying device 10 of the embodiment is as described above. As shown in FIG. 7, the fishing line L fed from the bobbin B to the fishing line tension applying device 10 is tensioned by the tension roller 12, and after the magnitude and numerical value of the tension are measured by the tension meter 13, it is wound onto the reel R. When the numerical value measured by the tension meter 13 is not the desired magnitude, the knob 12d is rotated to vary the rotational resistance of the tension roller 12, and adjustment is performed so that the tension applied to the fishing line L becomes the desired magnitude.

[0050] The embodiments disclosed this time are illustrative in all respects and not restrictive. The scope of the present invention is indicated by the claims, and includes all modifications and changes within the scope and equivalent meanings thereof.

[0051] For example, in the embodiment, a pair of tension rollers 12 are used, but even if a single tension roller 12 is used and the fishing line L is wound around the tension roller 12 a plurality of times, tension can be applied to the fishing line L due to the friction between the fishing line L and the small diameter portion 12b and the rotational resistance of the tension roller 12.
