Description

  The present invention relates to a floating structure used for fishing, in particular, a floating structure applied to so-called wing fishing.

  There is a fishing genre called “floating fishing”. Floating fishing is intended to catch fish using an item that is literally called “floating”, but in particular, it is a fishing method that employs a mechanism that suppresses the weight to about 10 grams at most. FIG. 11 is a schematic diagram showing a state of fishing by a general floating-floating fishing device, and FIG. 12 is a schematic diagram showing a state where the device is stable in the sea.

  As shown in the figure, in floating fishing, the device 1 includes a road line 2, a Harris 3 connected to the road line 2 via a connecting tool 7 (usually referred to as "Salkan"), and a Harris 3 A fishing hook 4 provided at the tip of the sword and a float 5 attached to the road thread 2. Various specifications of the float 5 have been proposed in the past, but in this device 1, the float 5 is of a so-called center-through type. The center-type float 5 is generally formed in a spindle shape as shown in the figure, and has a built-in weight for adjusting buoyancy. Further, the float 5 is formed with a thread insertion hole 11 along the longitudinal direction thereof, and the road thread 2 is inserted into the thread insertion hole 11, and the float 5 freely slides along the road thread 2. Be able to.

  The float 5 is provided with a predetermined buoyancy in a state where it is inserted into the sea, and thereby floats in an upright posture in the vicinity of the sea surface 6 along the vertical direction. Usually, the float 2 is provided with the float 2 so that the float 5 slides between the salcan 7 and the float 8. In order to stably arrange the device 1 in the sea, a weight 9 is appropriately attached to the Harris 3. The weight 9 is usually referred to as a “ball ball”, and various sizes are prepared in advance. The weight 9 is set to have a weight of about 0.06 g to 3 g depending on its size.

  When the device 1 constructed as described above is thrown into the sea, the fishhook 4 etc. sinks into the sea due to the gravity acting on the fishhook 4, Harris 3, gunball 9, salcan 7 etc. It slides along the direction of the arrow 10 relative to the float 5 that floated on the surface. Then, as shown in FIG. 12, the device 1 is stabilized in the sea when the float 8 provided on the road thread 2 comes into contact with the float 5.

  By the way, the state of the sea changes from moment to moment, and in some cases, the tide becomes faster and the wind becomes stronger. As shown in FIG. 12, in the conventional float 5, the road yarn 2 once rises from the sea surface and is then inserted into the float 5. As a result, the problem that the device 1 in the sea was lifted to the sea level 6 side was pointed out. In order to solve this problem, conventionally, a float that floats in the vicinity of the sea surface has been proposed (see, for example, Patent Document 1). According to such a float, the road line floats smoothly from the sea surface. It is inserted into the inside.

JP-A-11-289936

  Conventional buoys that are inclined near the sea surface include an eccentric weight for changing the position of the center of gravity in addition to a weight for adjusting buoyancy. However, when such an eccentric weight is adopted, new parts are required separately, and a process for mounting the eccentric weight separately from the buoyancy adjustment weight is required in the float manufacturing process. Therefore, there was a problem that the manufacturing cost of the float rose significantly.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a flounder fishing float that can be manufactured at a low cost with a simple structure and takes an inclined posture near the sea surface.

  (1) In order to achieve the above-described object, the float for fishing of a flounder according to the present application includes a floating body through which a thread insertion hole is formed and a weight for adjusting buoyancy fitted in the thread insertion hole, and the buoyancy adjustment The weight is composed of an asymmetrical annular member centered on the central axis of the thread insertion hole.

  According to this configuration, when the buoyancy adjustment weight is fitted into the thread insertion hole, the buoyancy adjustment weight forms a part of the thread insertion hole, and the fishing line (such as a road line) passes through the floating body. In other words, the float for fishing is a center-type float. Moreover, since the buoyancy adjustment weight is made of an asymmetrical annular member, the center of gravity of the buoyancy fishing float is biased by attaching the buoyancy adjustment weight to the floating body. Therefore, when the float for fishing is inserted into the sea, it can float in a state of being inclined near the sea surface. Further, since the center of gravity is biased, a single weight for adjusting the buoyancy is employed, so that the manufacturing process of the float for fishing for the flocculation is not complicated.

  (2) The buoyancy adjusting weight may be constituted by a pipe member having a part cut away. In this configuration, a part of the pipe member is notched so that the asymmetric annular member is easily formed. Therefore, it is possible to reduce the manufacturing cost of the flounder fishing float by reducing the parts cost of the flounder fishing float.

  (3) Further, the floating body is preferably formed in an elongated spindle shape in which the ratio of the maximum radial dimension to the maximum axial dimension is 1/3 to 1/4. In this configuration, since the floating main body is disposed in a state of being laid near the sea surface, the floating float for fishing is extremely visible to the angler. However, when a fish comes into contact with the device (when so-called “Atari” occurs), the floating body lying near the sea surface will stand up in the sea, and visibility for the angler will be greatly reduced. This is because when the floating body stands up in the water, the angler can only visually recognize the end of the floating body formed in an elongated spindle shape. That is, the angler can clearly see the float for fishing before the atari occurs, whereas it becomes difficult for the angler to visually recognize the float for fishing after the atari occurs. This means that the angler can reliably catch the atari.

  (4) In addition, it is preferable that the end of the floating main body has a color with poor visibility. In this configuration, when the above-mentioned hit occurs, it becomes more difficult for the angler to visually recognize the floating float for fishing, and in some cases, the floating float for fishing disappears from view at the same time as the angler. become. Therefore, there is an advantage for the angler that the atari can be captured more reliably.

  As described above, according to the present invention, the buoyancy adjustment weight that defines the buoyancy is composed of a single asymmetrical annular member, so that the number of parts and the assembly cost of the float for fishing are not increased. Float fishing floats that float near the sea surface are provided at low cost with a simple structure.

  Hereinafter, the present invention will be described in detail based on preferred embodiments with appropriate reference to the drawings.

<First Embodiment>
FIG. 1 is a cross-sectional view of a floating float for fishing (hereinafter simply referred to as “floating”) according to a first embodiment of the present invention, and shows a state where it is actually used.
The float 20 is configured to float in an inclined posture near the sea surface 21, and includes a float main body 22 and a sleeve 23. The feature of the float 20 according to the present embodiment is that the buoyancy adjustment weight 26 constituting the sleeve 23 is formed in a shape described later, whereby the float 20 is inexpensive by a simple manufacturing process. It is a point that has come to be manufactured.

  The floating body 22 is formed in a spindle shape as shown in the figure, and is made of, for example, resin, wood or the like. However, the outer shape of the floating body 22 is not limited to the spindle shape, and a conical shape and other various shapes can be adopted. A through hole is formed in the center of the floating body 22 along the axial direction, and a sleeve 23 is fitted and fixed in the through hole. The sleeve 23 is formed in an annular shape as will be described later, and constitutes a thread insertion hole 25 through which the road thread 24 is inserted. Therefore, the float 20 is a so-called threading type. In the figure, the road thread 24 is inserted into the thread insertion hole 25.

FIG. 2 is an exploded perspective view of the sleeve 23.
The sleeve 23 includes a buoyancy adjustment weight 26 and a fitting member 27 fitted to the weight. In the figure, the buoyancy adjusting weight 26 and the fitting member 27 are shown separated from each other, but they are joined together to form a cylindrical sleeve 23.

  The buoyancy adjusting weight 26 is made of a metal having a relatively large specific gravity, such as brass, lead, or tungsten alloy. The buoyancy adjusting weight 26 includes an annular portion 28 and an extending portion 29 continuous therewith. The annular portion 28 defines a part of the thread insertion hole 25. In other words, the buoyancy adjusting weight 26 has a shape in which a part of a cylindrical member is cut by a virtual cutting surface along the axial direction, and is an asymmetrical annular shape around the central axis of the thread insertion hole 25. It is configured as a member.

  On the other hand, the fitting member 27 is made of a material having a specific gravity smaller than that of the material constituting the buoyancy adjusting weight 26 such as resin, and the shape thereof is substantially the same as that of the buoyancy adjusting weight 26. That is, the fitting member 27 includes an annular portion 30 and an extending portion 31. The annular portion 30 has the same shape as the annular portion 28 of the buoyancy adjusting weight 26. The extending portion 31 is disposed opposite to the extending portion 29 of the buoyancy adjusting weight 26, and the end surface of the extending portion 29 of the buoyancy adjusting weight 26 is brought into contact with the inner end surface 32 of the annular portion 30. The buoyancy adjusting weight 26 and the fitting member 27 are fixed by, for example, an adhesive or the like, thereby forming a single sleeve 23.

3 and 4 are a sectional view taken along line III-III and a sectional view taken along line IV-IV in FIG. 2, respectively.
As shown in these drawings, the extending portion 29 of the buoyancy adjusting weight 26 and the extending portion 31 of the fitting member 27 are both curved in an arc shape, and are arranged so as to face each other (see FIG. 4), and is formed in an annular shape as a whole. The internal space of both forms the thread insertion hole 25. In this embodiment, the extending portion 31 of the fitting member 27 mainly forms the thread insertion hole 245, but the extending portion 29 of the buoyancy adjustment weight 26 mainly functions as the thread insertion hole 25. May be formed.

  Since the center of gravity of the sleeve 23 formed in this manner is biased, the center of gravity of the float 20 is also biased from the center of the thread insertion hole 25 when the sleeve 23 is fitted into the through hole of the float body 22. In actual fishing, the float 20 floats in a posture inclined near the sea surface 21 as shown in FIG. Accordingly, the road thread 24 is smoothly inserted into the thread insertion hole 25. In addition, since the center of gravity of the float 20 is biased, a single buoyancy adjustment weight 26 is employed, so that it is not necessary to incorporate another member for biasing the center of gravity as in the prior art. Since special processing to the floating body 22 is not required, the manufacturing process of the floating body 20 is simple and can be manufactured at low cost.

  In particular, in this embodiment, the buoyancy adjusting weight 26 has a shape in which a part of the pipe member is cut out. Therefore, the asymmetrical buoyancy adjusting weight 26 is easily and inexpensively manufactured. Therefore, the parts cost of the float 20 is also reduced. As a result, the float 20 has an advantage that it is manufactured at a lower cost.

  In this embodiment, the fitting member 27 is fitted to the buoyancy adjusting weight 26 to form the cylindrical sleeve 23, and the road thread 24 can be inserted through the thread insertion hole 25 very smoothly. . However, the fitting member 27 may be omitted.

  5 and 6 are perspective views of the sleeves 33 and 34 according to the first and second modifications of the present embodiment, respectively.

  The sleeve 33 according to the first modified example has a cylindrical shape, and includes a buoyancy adjusting weight 35 and a fitting member 36. The buoyancy adjustment weight 35 is made of metal such as brass, and the fitting member 36 is made of resin. In this modified example, a cylindrical member is cut at a virtual cutting surface that intersects the longitudinal direction, so that one constitutes a buoyancy adjustment weight 35 and the other constitutes a fitting member 36. .

  On the other hand, the sleeve 34 has a cylindrical shape and is made of a metal such as brass. In this modification, the sleeve 34 also serves as a buoyancy adjustment weight. As shown in FIG. 6, the sleeve 34 is partly cut away along the circumferential direction to form a window portion 37. As the sleeve 34 is cut out in this way, the center of gravity of the sleeve 34 is deviated from the center thereof, and as a result, the center of gravity of the float 20 is also deviated.

<Second Embodiment>
Next, a second embodiment of the present invention will be described.
FIG. 7 is a front view of a float 40 according to the second embodiment of the present invention, and FIG. 8 is a cross-sectional view.

  The difference between the float 40 according to the present embodiment and the float 20 according to the above embodiment is that the outer shape of the float main body 41 is formed in an elongated spindle shape, and a design change necessary for that is applied to the sleeve 42. The point and the head 43 (end part) of the floating main body 41 are points where a coating with low visibility is applied. The other configuration is the same as that of the float 20 described above.

  The floating body 41 is made of resin, wood, or the like. The longitudinal dimension L of the floating body 41 is appropriately set in the range of 40 mm to 60 mm, and the outer diameter dimension D is appropriately set in the range of 8 mm to 15 mm. In this case, the ratio between the dimension L and the dimension D is set in the range of 1/3 to 1/4. A through hole is formed in the center of the floating body 41 along the longitudinal direction, and a sleeve 42 is fitted into the through hole.

  The floating main body 41 is coated with a paint having excellent visibility such as fluorescent orange or fluorescent yellow except for the head 43. The head 43 of the floating body 41 is coated with silver paint in the present embodiment, but is not limited to this color, and may be any color that is generally inferior to a fisherman.

  The sleeve 42 includes a buoyancy adjusting weight 44 made of metal such as brass and a fitting member 45 made of resin. Like the sleeve 23 according to the first embodiment, the buoyancy adjusting weight 44 and the fitting member 45 are provided with annular portions 47 and 48 and extended portions 49 and 50, respectively, and are fitted into each other to form a cylinder. A sleeve 42 is formed. The inner space of the sleeve 42 constitutes the thread insertion hole 25. However, in this embodiment, since the outer shape of the floating body 41 is an elongated spindle shape, the outer diameter dimension of the lower end portion 46 is reduced. Therefore, the annular portion 47 of the buoyancy adjusting weight 44 is brought into contact with the lower surface of the floating body 41, and the sleeve 42 is inserted into the floating body 41 in this state.

9 and 10 are views showing the posture of the float 40 near the sea surface during actual fishing.
Since the sleeve 42 has the above-described configuration, the center of gravity is also biased in the float 40 according to the present embodiment. The floating body 41 is formed in the elongated spindle shape as described above. From these things, at the time of actual fishing, as FIG. 9 shows, the floating main body 41 is arrange | positioned in the state which lay down in the sea surface 21 vicinity. Therefore, the road thread 24 is smoothly inserted into the thread insertion hole 25, and the float 40 is very highly visible to the angler.

  Here, when a fish comes into contact with the device (when a so-called “Atari” occurs), as shown in FIG. 10, the floating body 41 lying near the sea surface 21 stands up in the sea. That is, the float 40 has its head 43 facing the angler. For this reason, it is difficult for the angler to visually recognize the float 40. However, for the angler, the float 40 floating near the sea surface 21 suddenly becomes difficult to see, so it can be easily determined that it is “Atari”.

  However, in this embodiment as well, the buoyancy adjustment weight 44 having the above-described structure is employed to bias the center of gravity of the float 40, so that the float floats at a low cost in the same manner as the float 20 according to the first embodiment. There is an advantage that 40 is manufactured.

  In addition, in the present embodiment, the head 43 of the floating main body 41 is provided with a color that is inferior in visibility. Therefore, when the “atari” occurs, the angler can visually recognize the floating 40. It becomes difficult. Therefore, when viewed from the angler, the float 40 disappears from the field of view at the same time as the attack, and the angler has the advantage that the “atari” can be captured more reliably.

  The present invention can be applied to fishing floats, in particular to floats used for floating float fishing.
