Description

  The present invention relates to a structure of a snowflake used for so-called blunt fishing.

  One of the fishing genres is "Fukase fishing". Although there is no clear definition of Fukase fishing, in general, a bait attached to the tip of a fishing line is equipped with a bait, and the bait, the hook, and the weight (extremely light weight) of the bait make the bait a natural condition in water. It is said that it is a fishing method that invites the bite of the target (fish that is the target of fishing) by submerging in. This fishing method is delicate and greatly affected by the environment of the fishing ground such as the wind because the simple and lightweight device as described above is adopted. In order to mitigate the effect, in actual fishing, a fisherman sometimes attaches a weight called a gunball to the fishing line, which intentionally increases the weight of the tackle, and dives the tackle (i.e., attaches to the hook). There is also a case where a fishing tackle having a predetermined buoyancy is attached to the fishing line in order to regulate or control the feeding of the fish. Fukase fishing using such a duck is also called ukifuka fishing.

  The angler appropriately adjusts the size of the gunball and adjusts the weight of the tackle according to the environment of the fishing ground, but the buoyancy of the float must also be adjusted accordingly. Usually, since the buoyancy of the duck is a physical property of the duck and is unique to the duck, the fisherman needs to appropriately replace the duck according to the weight of the tackle in actual fishing.

  However, in the case of using a so-called middle-end type duck, the fishing line must be cut once during the duck replacement work, and the duck replacement work in actual fishing is very troublesome for the fisherman. In order to solve this problem, there has been conventionally proposed a float that can change the buoyancy (see Non-Patent Document 1, for example). This conventional buoyancy adjusting device is capable of adjusting the buoyancy of about 1.5 g weight, and can be adjusted in the range of 0 to 4B as a weight load display.

  By the way, after all, in Ukifu-Kase fishing, the fisherman operates the fishing line through the rod and reel while taking into consideration the conditions of the fishing ground (wind, waves, water flow, etc.), and the point at which water is attached to the fishing hook It is called "Tana", and it is the action of delivering to a target at a specific depth at a specific water depth. In order to perform this operation accurately, in recent years, a fishing method called "sinking fishing" is considered to be effective. The submersible fishing is a condition in which the buoyancy of the duck is adjusted to a neutral buoyancy, and the fisherman deliberately infiltrates the duck while carrying the entire tackle to the above point.

  In this fishing method, the sea bass is extremely important as a tool for controlling or controlling the dive of the bait attached to the fishing hook. Moreover, as mentioned above, since the fishing tackle of Fukase fishing is extremely lightweight, in order for the fisherman to accurately control the dive of the bait attached to the fishing hook, the buoyancy of the broom is required to be in the unit of 0.01 g. To be done. In other words, whether or not the buoyancy exerted by the Uki is set with extremely high accuracy determines whether the Uki as a tool is good or bad.

  However, when Uki is provided as an industrial product, there is a limit to the accuracy of buoyancy setting due to the processing accuracy in manufacturing. Moreover, when the fishing field is the sea, the salt concentration of seawater is not always constant and varies depending on the season and weather. Due to these circumstances, fluctuations in the buoyancy of the broom during actual fishing are an unavoidable problem even if the processing accuracy of the broom is sufficiently improved.

  The present invention has been made under such a background, and an object thereof is to provide a fishing tackle capable of precisely adjusting buoyancy.

(1) The inventor of the present application thought that the above object could be achieved by finely adjusting the volume of the fishing tackle with a component having an outer shape as small as possible. Therefore, fishing float according to the present invention, have a peripheral surface, the through-hole and the through hole and along the radial direction from the outer peripheral surface extending in the axial direction is formed along the axial direction through the center A hollow body provided with a slit that communicates with the piston , a piston liquid-tightly provided on the outer peripheral surface so that the amount of protrusion of theukiki body with respect to the outer peripheral surface is adjusted, and the piston penetrates through the center in the axial direction. It has a fishing line insertion hole formed along it, and a tubular fitting shaft removably inserted into the through hole of the above-mentioned main body .

According to this configuration, the protrusion amount of the piston relative to the outer peripheral surface of the walker body is adjusted, so that the volume of the walker body changes. During actual fishing, the main body of the snow is thrown into the water together with the piston, but since the piston is liquid-tightly provided on the outer peripheral surface, even if the amount of protrusion changes, water is prevented from entering the snow body. To be done. That is, even if the amount of protrusion of the piston changes, the weight of the fishing tackle does not change and the volume changes. Moreover, the outer shape of the piston is not particularly limited and can be designed compact. That is, the volume of the fishing float is finely adjusted. Further, in a state where the fishing line is inserted into the fishing line insertion hole of the tubular fitting shaft, the fishing line is moved from the slit to the through hole of the snow body, and the tubular fitting shaft is inserted into the through hole of the snow body. It When the tubular fitting shaft is pulled out from the through hole, the fishing line can also be detached from the skid main body through the slit. That is, the fishing line main body can be easily replaced without cutting the fishing line.

  (2) It is preferable that the piston has a piston main body and a cylinder that is embedded in the blowout main body and has a piston main body accommodating chamber that is open to the outer peripheral surface and is continuous with the opening. It is preferable that the piston body is fitted into the piston body accommodating chamber in an airtight manner through the opening.

  In this configuration, the piston body slides in an airtight manner with respect to the cylinder, and moves in and out of the piston body accommodating chamber. Therefore, the protrusion amount of the piston is adjusted with higher accuracy.

  (3) It is preferable that the blow body has a hollow structure and serves also as the cylinder.

  With this configuration, the weight of the main body of the snow can be reduced. In addition, the number of parts forming the fishing tackle is reduced.

  (4) The piston body is composed of a cylindrical member having a predetermined outer diameter and has an O-ring surrounding the piston body in the circumferential direction, and the O-ring is pressed against the inner wall surface of the piston body accommodating chamber. Is preferred.

  According to this structure, the piston body can be designed compactly, and water can be surely prevented from entering the ski body with a simple structure.

  (5) The piston body is preferably screwed into the cylinder.

  According to this structure, the amount of protrusion of the piston with respect to the outer peripheral surface of the above-mentioned blowout body is finely adjusted very accurately by the rotation of the piston body.

  (6) It is preferable that a tool engagement groove is formed on the crown of the piston body.

  With this configuration, the piston body can be easily and accurately rotated using a tool.

  According to the present invention, the piston having a compact design is provided for the blower body, and the amount of protrusion from the outer peripheral surface of the blower body is adjusted, so that the weight of the blower body remains constant and its volume is accurate. Fine-tuned to. Therefore, the buoyancy of the fishing float is finely adjusted accurately.

It is needless to say that the present embodiment is only one aspect of the fishing tackle according to the present invention, and the embodiment may be changed without changing the gist of the present invention.

1. First embodiment

<Schematic configuration and characteristic points>

  FIG. 1 is a schematic view of a fishing tackle using a fishing tackle according to a first embodiment of the present invention.

  The fishing tackle 10 is applied to so-called ukifukase fishing. The fishing tackle 10 includes a line 13 inserted through and supported by a line guide 12 of a fishing rod 11, a fishing tackle 14 attached to the line 13, and a Harris 16 connected to the tip of the line 13 via a sulcan 15. And a fishing hook 17 connected to the Harris 16. The fishing tackle 14 is a so-called through type and can slide along the line 13. A float member 18 is attached to a predetermined position of the line 13, and the sliding of the fishing float 14 is restricted at that position. By adjusting the position of the floating member 18, the distance from the fishing float 14 floated on the water surface to the fishing hook 17 is set.

  The fishing tackle 14 is provided with a skid main body 20 having a piston 19 and a fitting shaft 21 (corresponding to a "cylindrical fitting shaft" described in the claims) which is inserted into and removed from the skid main body 20. .. The features of the fishing tackle 14 according to the present embodiment are: (1) The volume of the fishing tackle body 20 is changed by providing the piston 19 on the fishing tackle body 20 as described later (that is, the fishing tackle 14 Buoyancy is adjusted when it is put into water), and (2) as shown in the same figure, the fitting shaft 21 is inserted into or removed from the bottom body 20 from below. The snow body 20 is attached to and detached from the line 13 without cutting the line 13 (that is, the fitting shaft 21 is inserted into the snow body 20 to attach the snow body 20 to the line 13 and will be described later). As described above, the fitting shaft 21 is removed from the broom body 20 so that the broom body 20 is removed from the line 13).

<Piston>

  FIG. 2 is a sectional view of the fishing tackle 14. Further, FIG. 3 is an enlarged view of a main part of FIG. 2, and shows a mounting structure of the piston 19.

  As shown in FIG. 3, the piston 19 includes a piston body 71 and a cylinder 72. The lower end of the cylinder 72 is closed and the upper end is open. The cylinder 72 is made of metal in addition to resin. As shown in FIG. 2, the cylinder 72 is embedded in the snow body 20. The upper end surface 76 of the cylinder 72 is smoothly continuous with the outer peripheral surface 73 of the walker main body 20, and therefore the opening 74 is formed in the outer peripheral surface 73. A storage chamber 75 (corresponding to a “piston body storage chamber” recited in the claims) is defined inside the cylinder 72 so as to be continuous with the opening 74. In the present embodiment, the cylinder 72 has a cylindrical shape, and the inner wall surface of the storage chamber 75 has a circular shape.

  The piston body 71 is a columnar member. The piston body 71 is made of resin or metal. The outer diameter of the piston body 71 corresponds to the inner diameter of the cylinder 72. In order to help understanding of the structure, a gap is clearly formed between the piston body 71 and the cylinder 72 in FIG. 2, but in reality, both are fitted with a predetermined fitting tolerance, The piston body 71 can slide in a liquid-tight manner with respect to the cylinder 72.

  The outer shape of the piston body 71 corresponds to the inner wall surface shape of the cylinder 72. However, as long as they correspond to each other, the outer shape of the piston body 71 and the inner wall surface shape of the cylinder 72 are not particularly limited. In this embodiment, the piston body 71 includes an O-ring 77. The O-ring 77 is arranged at a substantially central portion of the piston main body 71 and surrounds the outer peripheral surface 78 of the piston main body 71. The O-ring 77 projects radially from the outer peripheral surface 78 of the piston body 71, and the outer diameter of the O-ring 77 is larger than the inner diameter of the cylinder 72. A peripheral groove may be formed on the outer peripheral surface 78 of the piston body 71, and the O-ring 77 may be fitted into this peripheral groove. In this case, the O-ring 77 is positioned on the piston body 71 and held with a constant holding force.

  The piston body 71 is fitted in the cylinder 72 along the direction of arrow 79. The outer diameter of the piston body 71 corresponds to the inner diameter of the cylinder 72, and the above-mentioned fitting tolerance is set, so that the gap between the two is extremely small. The O-ring 77 is elastically deformed and fitted into the cylinder 72, and is pressed against the inner wall surface of the cylinder 72. As a result, the piston body 71 is liquid-tightly and air-tightly fitted into the cylinder 72, and as shown in FIG. 2, the accommodation chamber 75 is kept air-tight and liquid-tight by the piston body 71.

  The piston body 71 can slide along the longitudinal direction of the cylinder 72. In this case, since the fitting tolerance is set between the outer diameter of the piston body 71 and the inner diameter of the cylinder 72, a predetermined frictional force is generated between the piston body 71 and the cylinder 72. Therefore, although the pressure in the accommodating chamber 75 changes depending on the sliding of the piston body 71 or the depth of the duck body 20 submerged in water, the friction force of the piston body 71 against the cylinder 72 is sufficient. The piston body 71 is prevented from unintentionally sliding with respect to the cylinder 72 by being set to be large. That is, the piston body 71 is positioned with respect to the cylinder 72. Although the O-ring 77 is provided on the piston main body 71 in the present embodiment, another elastic member may be provided on the piston main body 71 instead of the O-ring 77. Further, at least one of the piston body 71 and the cylinder 72 may be made of an elastic body.

<Mating axis>

  4 is a front view of the fitting shaft 21, FIG. 5 is a right side view of the fitting shaft 21, and FIG. 6 is a vertical sectional view of the fitting shaft 21. 7 is a sectional view taken along line VII-VII in FIG. 4, and FIG. 8 is a sectional view taken along line VIII-VIII in FIG.

  As shown in FIG. 2, the fitting shaft 21 is fitted in a through hole 22 provided in the snow body 20. As will be described later, the through hole 22 passes through the center of the broom body 20 and penetrates the broom body 20 in the axial direction (vertical direction in the figure: the direction of arrow 69). The fitting shaft 21 is adapted to be inserted into and removed from the through hole 22 in the direction of the arrow 69, that is, along the axial direction of the fitting shaft 21.

  As shown in FIGS. 4 and 6, the fitting shaft 21 is a cylindrical member. In the present embodiment, the fitting shaft 21 is made of resin (typically, acrylonitrile butadiene styrene copolymer (ABS), polypropylene (PP), polyoxymethylene (POM)). However, the material forming the fitting shaft 21 may be a metal as well as a resin. The fitting shaft 21 has a fishing line insertion hole 23. The fishing line insertion hole 23 penetrates the center of the fitting shaft 21 and is formed along the axial direction of the fitting shaft 21. The line 13 (see FIG. 1) is inserted into the fishing line insertion hole 23. The inner diameter of the fishing line insertion hole 23 can be set in the range of 1.0 mm to 3.0 mm. Thereby, lines having various wire diameters can be inserted into the fishing line insertion hole 23.

  The fitting shaft 21 includes a main cylindrical portion 24, a knob portion 25, a locking rib 26, and a guide cylindrical portion 27, which are integrally formed in the present embodiment.

  The main cylindrical portion 24 is set to have a predetermined outer diameter dimension d1 (see FIG. 6). The dimension d1 corresponds to the inner diameter of the through hole 22 (see FIG. 2) provided in the skive main body 20, and a predetermined fitting tolerance is set between the two. In the present embodiment, the inner diameter of the through hole 22 is set to 5.0 mm, while the outer diameter dimension d1 of the main cylindrical portion 24 is set to 5.0 mm. That is, the main cylindrical portion 24 is pushed into the through hole 22 of the walker body 20, and a constant frictional force is generated between the main cylindrical portion 24 and the walker body 20. Therefore, the fitting shaft 21 is always held by the skive main body 20 with a constant holding force. When a fisherman intentionally inserts or removes the fitting shaft 21 into or from the skimming body 20, the fisherman inserts the fitting shaft 21 by operating the fitting shaft 21 with a force exceeding the frictional force. You can take it off.

  As shown in FIG. 4, the knob 25 is provided at the lower end of the main cylindrical portion 24. The knob 25 projects from the snow body 20 with the fitting shaft 21 inserted into the through hole 22 (see FIGS. 1 and 2). That is, with the main cylindrical portion 24 completely fitted in the through hole 22, the knob portion 25 projects downward from the lower end of the walker body 20. The outer shape of the picking portion 25 is formed so that a fisherman can easily and reliably pick it with the thumb and forefinger in the state shown in FIG. Specifically, the knob portion 25 is formed into a fan shape by flattening the lower end portion of the main cylindrical portion 24 into a flat plate shape. That is, the picking portion 25 has flat portions 28 and 29 (see FIG. 5) on both sides, and a fisherman can easily operate the fitting shaft 21 by pinching the flat portions 28 and 29 with fingers. You can do it.

  As shown in FIG. 6, the locking rib 26 is provided so as to project from the main cylindrical portion 24. As shown in FIGS. 5 to 8, the locking rib 26 is provided at the upper end of the outer peripheral surface of the main cylindrical portion 24, and projects in the radial direction of the main cylindrical portion 24. The locking rib 26 is a flat plate. The wall thickness t (see FIG. 5) of the locking rib 26 is set to a predetermined dimension. In the present embodiment, this wall thickness t can be set in the range of 1.2 mm to 1.8 mm. However, this wall thickness t corresponds to the width dimension d2 (see FIGS. 1 and 9) of the slit 32 provided in the walker main body 20. In the present embodiment, the width dimension d2 of the slit 32 is 1.2 mm to 2.0 mm, which is set to be slightly larger than the wall thickness dimension t. When the main cylindrical portion 24 is fitted into the through hole 22, the locking rib 26 is inserted into the slit 32. Since the width dimension d2 of the slit 32 is set to be slightly larger than the wall thickness dimension t of the locking rib 26, when the fitting shaft 21 moves relative to the skive main body 20, the locking rib 26 also. Slide inside the slit 32.

  As shown in FIGS. 4 to 6, the corner portion 30 on the upper end side of the locking rib 26 is chamfered. Further, the corner portion 31 on the lower end side of the locking rib 26 is also chamfered. That is, both are so-called C-plane processed. However, these may be formed in a curved surface. The effect of chamfering the corners 30 and 31 will be described later.

  The guide cylindrical portion 27 extends on the upper end of the main cylindrical portion 24 and is formed integrally with the main cylindrical portion 24. Since the guide cylindrical portion 27 is made of resin similarly to the main cylindrical portion 24, it can be easily elastically deformed. A through hole is provided in the axial direction so as to penetrate the center of the guide cylindrical portion 27. The through hole communicates with the fishing line insertion hole 23 that penetrates the main cylindrical portion 24. The guide cylindrical portion 27 is set to have a predetermined outer diameter d3 (see FIG. 6). The outer diameter d3 of the guide cylindrical portion 27 corresponds to the inner diameter dimension of the through hole 22 (upper part 36 described later: see FIG. 2) provided in the above-mentioned blow body 20, and a predetermined fitting tolerance is set between them. Has been done.

  In this embodiment, the outer diameter d3 of the guide cylindrical portion 27 is set to 4.0 mm (see FIG. 6). Therefore, the step portion 34 is formed at the boundary between the main cylindrical portion 24 and the guide cylindrical portion 27. Corresponding to this, as shown in FIG. 2, the intermediate portion 35 of the through hole 22 is reduced in diameter. That is, the inner diameter dimension of the upper portion 36 (portion into which the guide cylindrical portion 27 is inserted) of the through hole 22 above the intermediate portion 35 is set to 4.0 mm. Therefore, a constant frictional force is generated between the guide cylindrical portion 27 and the upper portion 36 of the through hole 22, and the guide cylindrical portion 27 is constantly attached to the skid main body 20 with a constant holding force. Retained. As described above, when the main cylindrical portion 24 is also fitted into the through hole 22, a constant frictional force is generated between the main cylindrical portion 24 and the skimming main body 20. When inserting or removing 21 into or from the skimming body 20, a fisherman can insert or remove the fitting shaft 21 by operating the fitting shaft 21 with a force exceeding these frictional forces.

  As shown in FIGS. 4 to 6 and 8, the guide cylindrical portion 27 includes a protrusion 33. The protrusion 33 is formed integrally with the guide cylindrical portion 27. The protrusion 33 is formed in a thin plate shape and protrudes in the radial direction of the guide cylindrical portion 27. That is, the protrusion 33 protrudes in the radial direction of the guide cylindrical portion 27 by the wall thickness a (see FIG. 6), and the wall thickness a can be set to 0.5 mm to 1.5 mm.

  The guide cylindrical portion 27 has a cut groove 37. The cut groove 37 extends in the axial direction of the guide cylindrical portion 27 and penetrates in the radial direction of the guide cylindrical portion 27. In particular, the cut groove 37 penetrates the guide cylindrical portion 27 in a direction orthogonal to the direction in which the projecting piece 33 projects. The function and effect of providing the cut groove 37 will be described later. Needless to say, the cut groove 37 may be omitted.

FIG. 14 and FIG. 15 are enlarged cross-sectional views of the main parts of the fishing tackle 14 with the fitting shaft 21 inserted in the broom body 20, showing how the fitting shaft 21 rotates with respect to the broom body 20. Has been done. 14 (a) and 15 (a) show the movement of the guide cylindrical portion 27, and FIGS. 14 (b) and 15 (b) show the movement of the main cylindrical portion 24.

  As shown in FIGS. 10 and 11, the outer shape of the snow body 20 is substantially spindle-shaped. As a material for forming the blowout main body 20, resin (typically, acrylonitrile butadiene styrene copolymer (ABS), polypropylene (PP), polyoxymethylene (POM)) is adopted in addition to wood. The snow body 20 includes the through hole 22. The through hole 22 extends in the axial direction of the snow body 20 from the upper end 38 of the snow body 20 to the lower end 39, and penetrates the center of the snow body 20. A recess 42 and an engagement recess 43 are formed inside the walker body 20 so as to be continuous with the through hole 22. The recess 42 and the engagement recess 43 will be described in detail later.

  The skive main body 20 has an upper main body 40 and a lower main body 41, which are assembled by fitting them vertically. The walker body 20 is divided in this way in order to facilitate the manufacture of the walkie body 20. That is, as described above, the snow body 20 includes not only the through hole 22 but also the recess 42 and the engaging recess 43 that are continuous with the through hole 22. The machining of the 42 and the engagement recess 43 is facilitated, and the manufacture of the skid main body 20 is simplified.

  The upper body 40 and the lower body 41 are divided by a dividing line 44. In the snow blower body 20 according to the present embodiment, as shown in the figure, the dividing line 44 is bent. Therefore, the concave line 45 that is recessed upward is formed on the outer edge portion of the lower surface 48 of the upper body 40, while the convex line 46 that protrudes upward is formed on the outer edge portion of the upper surface 49 of the lower body 41. Then, the concave line 45 and the convex line 46 are fitted to each other so that the lower surface 48 of the upper main body 40 and the upper surface 49 of the lower main body 41 are aligned with each other, and the skid main body 20 joined at the dividing line 44 is assembled.

  In this embodiment, as shown in FIG. 11, the positioning pin 50 is provided upright on the upper surface 49 of the lower body 41. Further, an engaging hole 51 is provided in the lower surface 48 of the upper body 42. The positioning pin 50 is fitted in the engagement hole 51, and the upper body 40 and the lower body 41 are aligned with each other in a fitted state. That is, the positioning pin 50 and the engagement hole 51 are fitted to each other so that the upper main body 40 and the lower main body 41 are aligned with each other, so that the skimming main body 20 can be accurately assembled. However, the positioning pin 50 and the engagement hole 51 may be omitted.

  The snow body 20 includes the slit 32 (see FIGS. 9 and 10). The slit 32 extends in the axial direction of the walker main body 20 and reaches from the upper end 38 to the lower end 39 of the walker main body 20. Further, the slit 32 is cut in the radial direction from the outer peripheral surface 73 of the snow body 20 and communicates with the through hole 22. As described above, the width dimension d2 of the slit 32 is preferably set in the range of 1.2 mm to 2.0 mm.

  As shown in FIGS. 10 and 11, the through hole 22 vertically penetrates the walker body 20 and has a reduced diameter at an intermediate portion 35 of the walker body 20. The inner diameter of the lower portion 52 of the through hole 22 below the intermediate portion 35 of the through hole 22 is set to be larger than the inner diameter of the upper portion 36.

  As shown in FIGS. 10 and 12, the recess 42 is continuous with the through hole 22 and extends downward from the intermediate portion 35. The recess 42 is provided inside the walker main body 20, extends in the circumferential direction around the through hole 22, and is formed in a fan shape as shown in FIG. That is, the recess 42 is continuous with the slit 32 and the through hole 22, extends in the radial direction, and extends in an arc shape with the through hole 22 as the center. In this embodiment, the central angle of the sector formed by the recess 42 is set to 90 ° (degree). However, the central angle is not limited to 90 °, but is set in the range of 45 ° to 180 °. However, this central angle is preferably set to about 90 °.

  As shown in FIG. 10, the wall surface 53 forming the recess 42 includes an inclined surface 54 and an inclined surface 55. The inclined surface 54 corresponds to the inclination angle of the corner portion 30 (see FIG. 4) on the upper end side of the fitting shaft 21. Further, the inclined surface 55 corresponds to the inclination angle of the corner portion 31 (see FIG. 4) on the lower end side of the fitting shaft 21. Therefore, the recess 42 is formed in a shape into which the locking rib 26 (see FIG. 4) can be fitted.

  As shown in FIGS. 10 and 13, the engaging recess 43 is formed continuously from the intermediate portion 35 and continuously with the through hole 22. The engagement concave portion 43 is provided above the concave portion 42 so as to be continuous with the concave portion 42 (see FIG. 12). The engagement recess 43 is also provided inside the skid main body 20, and is formed in a fan shape centering on the through hole 22. That is, the engaging recess 43 is formed continuously with the upper portion 36 of the through hole 22, extends in the radial direction, and extends in an arc shape around the upper portion 36. In the present embodiment, the central angle of the sector formed by the engagement recess 43 is set to 90 ° like the recess 42. However, the central angle is not limited to 90 °, but is set in the range of 45 ° to 180 °. However, this central angle is preferably set to about 90 °.

  As shown in FIG. 13, a claw portion 57 is projectingly provided on a wall surface 56 that defines the engagement recess 43. The claw portion 57 is composed of a ridge extending in the longitudinal direction of the through hole 22 (the axial direction of the snow body 20) and protrudes toward the center of the upper portion 36 of the through hole 22. Since the guide cylindrical portion 27 (see FIG. 4) of the fitting shaft 21 is fitted into the upper portion 36, when the fitting shaft 21 is rotated in that state, the protrusion provided on the guide cylindrical portion 27. 33 collides with the claw portion 57. The effect of the collision between the protrusion 33 and the claw 57 will be described later.

<How to use fishing float and its effects>

  The fishing tackle 14 according to this embodiment is mounted and used on the line 13 in the following manner in actual fishing.

  As shown in FIGS. 1 and 2, a fisherman inserts the line 13 into the fishing line insertion hole 23 of the fitting shaft 21. Accordingly, the fitting shaft 21 is always engaged with the line 13 and can freely slide along the line 13. The fisherman inserts the line 13 located above the fitting shaft 21 into the skid main body 21. Specifically, the fisherman holds the line 13 in his hand and slides the line 13 from the outer peripheral surface 73 of the duck body 20 to the through hole 22 through the slit 32 (see FIG. 2) of the duck body 21. That is, the line 13 is arranged in the through hole 22 through the slit 32.

  A fisherman inserts the fitting shaft 21 into the through hole 22 from below the duck body 20. That is, the fitting shaft 21 is pushed into the skid main body 20 from the guide cylindrical portion 27. At this time, the locking rib 26 provided on the main cylindrical portion 24 fits in the slit 32 and slides along the slit 32. As a result, the guide cylindrical portion 27 of the fitting shaft 21 is fitted to the upper portion 36 (see FIG. 10) of the through hole 22, and the main cylindrical portion 24 of the fitting shaft 21 is fitted to the lower portion 52 of the through hole 22. Can be matched. In this state, the position of the locking rib 26 provided on the fitting shaft 21 and the position of the recessed portion 42 provided on the walker body 20 are aligned, and the knob 25 provided at the lower end of the main cylindrical portion 24 is It projects from the lower end 39 of the snow body 20 (see FIG. 2).

  FIG. 14 is a diagram showing a relative positional relationship between the locking rib 26 and the concave portion 42 and a relative positional relationship between the protruding piece 33 and the engaging concave portion 43 in a state where the fitting shaft 21 is inserted into the skid main body 20. is there. Further, FIG. 15 is a diagram showing a relative positional relationship between the locking rib 26 and the concave portion 42 and a relative positional relationship between the projecting piece 33 and the engaging concave portion 43 when the fitting shaft 21 is rotated. ..

  Since the picking portion 25 is flat (see FIG. 2) and includes the flat portions 28 and 29 (see FIG. 5), a fisherman can easily grip the picking portion 25 with his / her fingers. When the fitting shaft 21 is simply inserted into the skid main body 20, as shown in FIGS. 14A and 14B, both the protruding piece 33 and the locking rib 26 are arranged in the slit 32.

  A fisherman can hold the knob 25 and rotate it 90 ° to the right. As shown in FIG. 15 (b), the locking rib 26 enters the recess 42, and the two are fitted together. When the fitting shaft 21 tries to slide in the axial direction, the corner portion 30 on the upper end side and the corner portion 31 on the lower end side (see FIG. 4) of the locking rib 26 are inclined surfaces 54 and 55 of the recess 42. (See FIG. 10), the locking rib 26 is restricted from sliding in the axial direction (see FIG. 2). That is, the concave portion 42 functions as a seat portion that supports the locking rib 26. For this reason, the fitting shaft 21 is positioned in the through hole 22 of the broom body 20 and cannot be removed from the broom body 20. Since the line 13 is inserted through the fitting shaft 21, the walker main body 20 is attached to the line 13 together with the fitting shaft 21 and can freely slide along the line 13.

  When the fishing tackle 10 is put into water, the fishing hook 17, the Harris 16, and the salcan 15 infiltrate, and the fishing tackle 14 relatively contacts the floating member 18. In this state, depending on the buoyancy exerted by the fishing float 14, the fishing float 14 floats or submerges on the water surface.

  As shown in FIG. 2, the piston 19 is provided in the broom body 20, and the fisherman operates the piston body 71 to project the protrusion amount (that is, the piston body with reference to the outer peripheral surface 73 of the broom body 20). The protrusion amount of 71) can be adjusted. Moreover, the piston main body 71 is fitted in the airtight main body 20 in a liquid-tight manner. Therefore, the volume of the duck body 20 is adjusted while the weight of the duck body 20 is kept constant, and as a result, the buoyancy exerted by the fishing duck 14 is adjusted. In this embodiment, the piston 19 is designed compact. The outer diameter of the piston 19 is not particularly limited, but may be set to about several mm in relation to the outer shape of the skid main body 20. Therefore, the buoyancy of the fishing tackle 14 is precisely and finely adjusted.

  In the present embodiment, the piston body 71 slides in a liquid-tight and air-tight manner with respect to the cylinder 72, and moves in and out of the accommodation chamber 75. Therefore, the amount of protrusion of the piston body 19 is adjusted with higher accuracy. Moreover, since the outer shape of the piston body 71 has a small columnar shape as described above, the buoyancy exerted by the fishing float 14 can be finely adjusted. As a result, for the fisherman, the buoyancy of the fishing tackle 14 can be precisely fine-tuned according to the conditions of the fishing ground (for example, changes in the seawater concentration), and comfortable fishing for skiing can be performed. In addition, in the manufacture of the fishing tackle 14, the buoyancy error due to the manufacturing error of the blow main body 20 or the like is offset by the above-mentioned protrusion amount of the piston main body 19. Therefore, the buoyancy intended by the designer is realized.

  However, the cylinder 72 may be omitted, and in that case, the accommodating chamber 75 may be formed directly in the walker main body 20.

  As shown in FIGS. 2 and 3, since the piston body 71 is formed in a cylindrical shape, the piston body 71 has an extremely simple structure, and the piston 19 is designed to be extremely compact. As a result, even if the fishing tackle 14 is small, it is possible to accurately adjust the buoyancy. An O-ring 77 is fitted in the piston body 71, and the O-ring 77 is pressed against the inner wall surface of the accommodation chamber 75. As a result, it is possible to reliably prevent water from entering the main body 20 of the fishing boat, and suppress a change in buoyancy during use of the fishing boat 14.

  Further, from the state where the fishing tackle 14 is attached to the line 13, the fisherman can grasp the knob 25 with his / her finger and rotate it to the left. As a result, as shown in FIG. 14, the engagement between the locking rib 26 and the recess 42 is released, and the locking rib 26 and the protruding piece 33 are arranged in the slit 32. The fisherman can pull the fitting shaft 21 downward while holding the knob 25, whereby the fitting shaft 21 is pulled out from the skid main body 20. The line 13 positioned above the fitting shaft 21 is easily pulled out from the main body 20 through the slit. In other words, the liner 13 is removed from the line 13 without cutting the line 13, and the fisherman can replace the liner 13 with another desired liner body.

  As described above, according to the fishing tackle 14 according to the present embodiment, the fisherman inserts the fitting shaft 21 into and removes the fitting shaft 21 to replace the fishing tackle body without cutting the line 13. You can Moreover, unless the fisherman intentionally operates the fitting shaft 21, the fitting shaft 21 is securely locked in the state where the fitting shaft 21 is fitted in the buki body 20, so that the buki body 20 easily comes off the line 13 in actual fishing. There is no such thing. In addition, since the fitting shaft 21 has a shape that is easy for a fisherman to operate, the fisherman can easily exchange the float in a short time in actual fishing.

  In the present embodiment, the concave portion 42 is formed so that the main cylindrical portion 24 of the fitting shaft 21 is rotated 90 ° about the axial direction as a rotation center (FIGS. 14B and 15B). reference). That is, when the angler operates the fitting shaft 21, the angler may rotate the fitting shaft 21 by 90 ° about the through hole 22 as a center of rotation. Therefore, the angler can easily operate the knob 25. .. If the fitting shaft 21 has to rotate significantly more than 90 ° (for example, more than 180 °), the fisherman must twist his wrist greatly, which is inconvenient. Further, if the fitting shaft 21 is set to rotate significantly smaller than 90 ° (eg smaller than 45 °), the fisherman may engage the engagement rib 26 with the recess 42. It will be difficult to confirm. On the other hand, in the present embodiment, since the fitting shaft 21 is rotated by 90 °, the fisherman may rotate the fitting shaft 21 until the locking rib 26 is orthogonal to the slit 32. .. That is, the operability is most excellent when the rotation angle of the fitting shaft 21 is set to about 90 °.

  Further, since the knob 25 is configured by flattening the lower end of the main cylindrical portion 24 of the fitting shaft 21 into a flat plate shape, the knob 25 can be easily integrated with the main cylindrical portion 24. Can be formed. As a result, the picking portion 25 is configured at a low cost, and thus the manufacturing cost of the fishing tackle 14 is reduced.

  Further, since the corner portion 30 on the upper end side of the locking rib 26 is chamfered (see FIG. 2), when the angler fits the fitting shaft 21 into the skid main body 20, the locking rib is engaged. The corner portion 30 on the upper end side of 26 is prevented from coming into strong contact with the inner wall surface of the recess 42. This is because the corner portion 30 on the upper end side and the inclined surface 54 (see FIG. 9) of the recess 42 tend to separate from each other due to the weight of the fitting shaft 21. Therefore, there is an advantage that the fisherman can smoothly rotate the fitting shaft 21. The inclined surface 54 or the corner portion 30 on the upper end side is formed so that a slight gap is formed between the corner portion 30 on the upper end side of the locking rib 26 and the inclined surface 54 forming the recess 42. It may be molded.

  Further, the corner portion 31 on the lower end side of the locking rib 26 is also chamfered (see FIG. 2), so that when the angler 31 fits the fitting shaft 21 into the skid main body 20, the locking rib 26 is locked. It is possible to prevent the corner portion 31 on the lower end side of the rib 26 from making surface contact with the inner wall surface of the recess 42. In other words, the corner portion 31 on the lower end side of the locking rib 26 can be chamfered so as to make line contact or point contact with the inclined surface 55 of the recess 42. As a result, the locking rib 26 can be securely engaged with the recess 42 without rattling, and can be smoothly slid with respect to the recess 42. As a result, the fisherman can operate the fitting shaft 21 more smoothly.

  In addition, in the present embodiment, the guide cylindrical portion 27 functions as a guide member when the fitting shaft 21 is inserted into the blowout body 20. Therefore, a fisherman can more easily fit the fitting shaft 21 into the through hole 22 of the skid main body 20. When the main cylindrical portion 24 of the fitting shaft 21 is fitted into the through hole 22, the position of the projecting piece 33 and the position of the engaging recess 43 match. Then, as the fisherman operates the picking portion 25 as described above, the projecting piece 33 collides with the claw portion 57 provided in the engaging recess 43, as shown in FIG. Here, since the fitting shaft 21 is made of resin and the guide cylindrical portion 27 can be elastically deformed, when the projecting piece 33 and the claw portion 57 collide with each other, the claw portion 57 is elastically deformed. Then, the protrusion 33 rides over the claw 57. That is, there is an advantage that a fisherman can obtain a so-called click feeling when operating the knob 25, and can confirm that the fitting shaft 21 and the skid main body 20 are fitted to each other.

  Further, in the present embodiment, as shown in FIG. 2, the step portion 34 is formed on the fitting shaft 21, and the intermediate portion 35 of the through hole 22 is correspondingly reduced in diameter. For this reason, when the fitting shaft 21 is fitted into the snow body 20, the step portion 34 comes into contact with the intermediate portion 35 of the through hole 22. Therefore, the fisherman can accurately position the fitting shaft 21 and the skid main body 20 only by confirming that the fitting shaft 21 is in contact with the intermediate portion 35, and confirms the contact between them. Only then, the fitting shaft 21 can be easily rotated.

  Further, the guide tubular portion 27 is provided with the cut groove 37. As described above, since the cut groove 37 penetrates in the direction orthogonal to the projecting direction of the projecting piece 33, when the projecting piece 33 crosses over the claw portion 57 (see FIG. 15A). ) The guide cylindrical portion 27 is elastically deformed more easily. That is, when the claw 57 and the protrusion 33 collide with each other, the guide cylindrical portion 27 is deformed so as to absorb the impact, and immediately after the protrusion 33 gets over the claw 57, the elastic deformation is caused. Immediately returned. Therefore, the fisherman can rotate the fitting shaft 21 more smoothly and has an advantage that a click feeling can be surely obtained.

  In the present embodiment, for the convenience of manufacturing the snow body 20, the snow body 20 is composed of an upper body 40 and a lower body 41, and the snow body 20 is assembled by fitting them together. .. However, it goes without saying that the snow body 20 may be integrally formed of resin.

2. Second embodiment

  Next, a second embodiment of the present invention will be described.

  FIG. 16 is a plan view of a snow body 60 according to the second embodiment of the present invention, and FIGS. 17 and 18 are XVII-XVII sectional views and XVIII-XVIII sectional views in FIG. 16, respectively.

  The snow body 60 has an outer shape similar to that of the snow body 20 according to the first embodiment, and includes a through hole 22 and a slit 32. The through holes 22 and the slits 32 have the same configuration as that provided in the walkie body 20 according to the first embodiment. Further, the walker body 60 includes an upper body 61 and a lower body 62, similar to the walker body 20, and the blower body 60 is assembled by fitting them together.

  The snow body 60 according to the present embodiment is different from the snow body 20 according to the first embodiment, whereas in the snow body 20, the upper body 40 and the lower body 41 are made of solid wood (FIG. 10 and FIG. 11), the upper main body 61 and the lower main body 62, which compose the blower main body 60, are formed in a hollow vessel shape. Since the upper body 61 and the lower body 62 have a hollow structure in this way, the upper body 61 and the lower body 62 can be easily configured by injection molding with resin. As a result, it is possible to mass-produce the main body 60 of the snow, and there is an advantage that the fishing snow 10 is provided at a low cost.

  Specifically, the upper body 61 includes an outer shell portion 63 and an inner shaft portion 64, and the lower body 62 also includes an outer shell portion 66 and an inner shaft portion 67. The outer shell portion 63 and the inner shaft portion 64 are integrally formed, and the outer shell portion 66 and the inner shaft portion 67 are integrally formed. The outer peripheral surface of the outer shell portion 63 and the outer peripheral surface of the outer shell portion 66 form the outer peripheral surface 73 of the walker body 60. In the present embodiment, a part of the outer peripheral surface 73 of the upper main body 61 is depressed to form a cylinder portion 80 (corresponding to the “cylinder” described in the claims). The cylinder portion 80 is formed in a cylindrical shape, and the inner diameter thereof matches the inner diameter of the cylinder 72 according to the first embodiment. The piston body 71 is adapted to be fitted into the cylinder portion 80. The lower end of the cylinder portion 80 is open and communicates with the internal space of the walker body 60. That is, the internal space of the snow body 60 also serves as the accommodation chamber 75. However, the bottom surface of the cylinder portion 80 may be closed.

  When the piston main body 71 is fitted into the cylinder portion 80, the piston main body 71 slides in an airtight manner with respect to the inner wall surface of the cylinder portion 80, as in the case of the walk body 20 according to the first embodiment. The fisherman can adjust the protrusion amount (that is, the protrusion amount of the piston body 71 with reference to the outer peripheral surface 73 of the broom body 60) by operating the piston body 71. Therefore, the volume of the snow body 60 is adjusted while the weight of the snow body 60 is kept constant.

  Also in the present embodiment, the buoyancy exerted by the fishing float 14 is accurately and finely adjusted. As a result, for the fisherman, the buoyancy of the fishing tackle 14 can be precisely fine-tuned according to the conditions of the fishing ground (for example, changes in the seawater concentration), and comfortable fishing for skiing can be performed. In addition, the buoyancy error based on the manufacturing error is canceled in the manufacture of the fishing tackle 14, and the buoyancy intended by the designer is realized. However, instead of the cylinder portion 80, the cylinder 72 according to the first embodiment may be fitted into the outer shell portion 63. Further, the cylinder 72 according to the first embodiment may be fitted inside the cylinder portion 80.

  The thickness dimension of the upper body 61 varies depending on the strength of the resin constituting the upper body 61, but can be set to about 1 mm to 3 mm. The outer shell portion 63 is formed in a substantially hemispherical shell shape, and the outer shape of the outer shell portion 63 is the same as the outer shape of the upper main body 40 of the walker body 20 according to the first embodiment. The inner shaft portion 64 is formed in a cylindrical shape, is provided at the center inside the outer shell portion 63, and projects downward (toward the lower body 62 side), as shown in FIGS. 17 and 18. The inner wall surface of the inner shaft portion 64 constitutes the upper portion 36 of the through hole 22. Then, similar to the walker main body 20 according to the first embodiment, the engaging recess 43 is provided continuously to the upper portion 36, and the claw 57 is formed on the wall surface 56 of the engaging recess 43. .. Further, the upper main body 61 has a groove 65 cut in the outer peripheral surface 73 in the radial direction, and the groove 65 constitutes a part of the slit 32.

  The lower body 62 includes an outer shell portion 66 and an inner shaft portion 67, and as described above, these are integrally formed like the upper body 61. The thickness dimension of the lower body 62 can be set to about 1 mm to 3 mm like the upper body 61. The outer shell portion 66 is formed in a substantially funnel shape, and the outer shape of the outer shell portion 66 is the same as the outer shape of the lower main body 41 of the walker body 20 according to the first embodiment. The inner shaft portion 67 is formed in a cylindrical shape, is provided at the center of the inner side of the outer shell portion 66, and projects upward (toward the upper body 61 side), as shown in FIGS. 17 and 18. The inner wall surface of the inner shaft portion 67 constitutes the lower portion 52 of the through hole 22. The recess 42 is provided continuously with the lower portion 52, similarly to the snow body 20 according to the first embodiment. Further, the lower body 62 has a groove 68 cut in the outer peripheral surface 73 in the radial direction, and the groove 68 constitutes a part of the slit 32.

  The upper body 61 is fitted in the lower body 62 in the vertical direction (axial direction). As a result, the outer peripheral surface 73 of the upper main body 61 and the outer peripheral surface 73 of the lower main body 62 are smoothly continuous, and the substantially spindle-shaped skid main body 60 is formed. Further, in the present embodiment, a so-called interlocking structure is provided on the surfaces of the outer shell portion 63 and the outer shell portion 66 that face each other. As a result, the upper main body 61 and the lower main body 62 are fitted to each other while being positioned. Further, as shown in the figure, the inner shaft portion 64 is also fitted to the inner shaft portion 67 with the outer shell portion 63 and the outer shell portion 66 fitted together. An interlocking structure is also provided on the surfaces of the inner shaft portion 64 and the inner shaft portion 67 that face each other, whereby the inner shaft portion 64 and the inner shaft portion 67 are reliably joined in a positioned state. ..

  In this way, by fitting the upper body 61 and the lower body 62 to each other, the groove 65 and the groove 68 are axially continuous to form the slit 32, and the inner shaft portion 64 and the inner shaft portion 67 are formed. And are joined to form the through hole 32. By inserting / removing the fitting shaft 21 (see FIG. 2) according to the above-described first embodiment into the duck body 60, a fisherman can easily attach / detach the duck body 60 to / from the line 13.

3. Modification of the embodiment

  Next, modified examples of the above-described embodiments will be described.

  FIG. 19 is a perspective view of a piston 85 according to a modified example of each of the above embodiments.

  The piston 85 according to this modification is different from the piston 19 according to each of the above-described embodiments in the structure of the piston 85. Specifically, the piston 85 has a cylinder portion 86 (see “Claim 86”). It corresponds to a "cylinder") and a screw shaft 87 (corresponding to a "piston body" described in the claims).

  The cylinder portion 86 is formed in a so-called stepped cylindrical shape and includes a large diameter portion 88 and a small diameter portion 89. The inner diameter of the large diameter portion 88 matches the inner diameter of the cylinder 72 (see FIG. 2) according to the first embodiment. The inner diameter of the small diameter portion 89 corresponds to the outer diameter of the shaft portion 90 of the screw shaft 87, and a female screw 91 is formed on the inner wall surface of the small diameter portion 89.

  The screw shaft 87 is made of resin or metal and includes the shaft portion 90 and the head portion 92. These are preferably integrally formed. The head portion 92 has a cylindrical straight portion 93 and a truncated cone-shaped top portion 94, and the outer diameter of the straight portion 93 is the outer diameter of the piston body 71 (see FIGS. 2 and 17) according to each of the above embodiments. Is consistent with The O-ring 77 (see FIGS. 2 and 17) according to each of the above-described embodiments is attached to the straight portion 93. A groove 97 (corresponding to the “tool engagement groove” described in the claims) is formed on the top surface 96 of the top portion 94. As shown in FIG. 19, the groove 97 is open to the top surface 96, and the inner wall surface shape is rectangular. The groove 97 extends in a direction perpendicular to the paper surface and penetrates the top portion 94. A tool (typically a flat-blade screwdriver) for rotating the screw shaft 87 engages with the groove 97.

  The shaft portion 90 is formed in a cylindrical shape, and its outer diameter is smaller than the outer diameter of the straight portion 93. A male screw 95 is formed on the shaft portion 90 and can be screwed with the female screw 91 of the cylinder portion 86. That is, when the shaft portion 90 is inserted into the large diameter portion 88 of the cylinder portion 86, the straight portion 93 of the head portion 92 is fitted into the large diameter portion 88. At this time, the shaft portion 90 is screwed into the small diameter portion 89 of the cylinder portion 86, and the screw shaft 87 is screwed in, so that the head portion 92 slides in the cylinder portion 86 in a liquid-tight and air-tight manner. .. Similar to the second embodiment, the lower end of the cylinder portion 86 is open, but the lower end may be closed.

  In this modification, since the screw shaft 87 is rotated, the protrusion amount of the head portion 92 of the screw shaft 87 (that is, the protrusion amount of the head portion 92 with respect to the outer peripheral surface 73 of the walker body 60) is extremely accurate. Fine-tuned to. That is, the buoyancy of the fishing float 14 is accurately adjusted.

  In particular, since the head portion 92 is provided with the groove 97, the angler can easily and accurately rotate the screw shaft 87 using a tool even if the size of the screw shaft 87 is small.
