Description

  The present invention relates to a floating structure used for fishing.

  There is a fishing genre called “floating fishing”. Floating fishing is intended to fish a fish using an item that is literally called “floating”. FIG. 8 is a schematic diagram showing a state of fishing by a general floating fishing device.

  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 connector 7 (usually referred to as “Salkan”), and a Harris 3 It has a fishhook 4 provided at the tip and a float 5 attached to the road thread 2. The float 5 is of a so-called threading type, and the road thread 2 is inserted into the float 5 (see, for example, Non-Patent Document 1). Thereby, the float 5 can slide freely along the road thread 2. However, in general, the float 2 is provided with the float 2 so that the float 5 slides between the salcan 7 and the float 8.

  When the device 1 configured 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, Sulcan 7, etc. 5 slides relative to 5 along the direction of arrow 10. Then, as shown in FIG. 9, 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. In this state, the distance from the float 5 to the fishhook 4 is particularly referred to as “tana”. This tana is a fish hit point expected by the angler, and the adjustment of this tana (that is, the position adjustment of the float 8) greatly affects the quality of the fishing results. In order to stably arrange the device 1 in the sea, a weight 9 (usually referred to as a “ball ball”) may be attached to the Harris 3 as appropriate.

  By the way, depending on the angler's experience, depending on the conditions of the fishing ground (tidal current speed, strength of waves and winds, degree of activity of fish, etc.), it may be possible to obtain better fishing results when the tana is not set. In such a case, the float 8 is removed, and the device 1 is set so that it sinks as much as possible. As a result, the fish hook 4 to which the food is attached is theoretically moved from the sea surface 6 to the sea bottom, so that the probability of a fish bite is increased. Such a mechanism mode is defined as “full floating mechanism”, while a mechanism mode in which the float 8 is used is defined as “semi-floating mechanism”.

Shimano Co., Ltd. 2003 Uki Fishing Guidebook

  In this way, semi-floating devices or full-floating devices are used depending on the conditions of the fishing ground, but the conditions of the fishing ground change every moment, especially the tidal velocity and the strength of the wind constantly change. It is. Therefore, in actual fishing, it is often the case that a situation in which it is preferable to change from a semi-floating mechanism to a full floating mechanism and from a full floating mechanism to a semi-floating mechanism is repeated.

  However, in order for the mechanism to be exchanged between semi-moving and full-moving, at least one of the attachment / detachment work of the float 8 and the exchange work of the float 5 is required. Such an operation is very troublesome for the angler. In particular, in competitions and the like for competing for fishing within the time limit, winning or losing is greatly affected by how quickly such a mechanism exchange operation is performed.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a fishing float that can freely change the mode of the mechanism between half-moving and full-moving without requiring operations such as attaching and detaching the floating device and exchanging the floating. It is to be.

  (1) In order to achieve the above object, the fishing float according to the present invention is provided with a thread insertion hole through which a fishing line is inserted, and includes an inner diameter adjusting mechanism that changes the inner diameter of at least a part of the thread insertion hole. It is characterized by that.

  In this configuration, the inner diameter of the yarn insertion hole is changed by the inner diameter adjusting mechanism. If the inner diameter of the thread insertion hole is set large, even if the fishing line is equipped with a buoyancy tool, the buoyancy tool can be inserted through the thread insertion hole. Can be configured. On the other hand, when the inner diameter of the thread insertion hole is set to be small, the float can not be inserted through the thread insertion hole, so that the device can be configured as a semi-floating type.

  (2) Further, since the above-described object is achieved, the fishing float according to the present invention is continuous with the floating body in which the thread insertion hole through which the fishing line is inserted is formed along the axial direction, and the thread insertion hole. A housing recess formed inside the floating body, a plurality of through holes having different inner diameters are provided, an inner diameter adjusting member housed in the housing recess, and the inside of the housing recess so that each through hole communicates with the thread insertion hole. And an attitude changing mechanism for changing the attitude of the inner diameter adjusting member.

  According to this configuration, the inner diameter adjusting member is accommodated in the accommodating recess of the floating body, and the inner diameter adjusting member can change its attitude in the accommodating recess via the attitude changing mechanism. Since the inner diameter adjusting member has a plurality of through holes having different inner diameters, any one of the plurality of through holes provided in the inner diameter adjusting member is changed by changing the posture of the inner diameter adjusting member. The hole communicates with the thread insertion hole. Therefore, in a state where the through hole having a large inner diameter communicates with the thread insertion hole, even if the fishing line is equipped with a buoyancy tool, the buoyancy tool can be inserted through the thread insertion hole. It can be configured as an idle type. On the other hand, in the state where the through hole having a small inner diameter communicates with the thread insertion hole, the floating device cannot be inserted through the through hole, so that the device can be configured as a semi-floating type.

  (3) The posture changing mechanism is realized by a structure in which the inner diameter adjusting member is rotatably fitted in the receiving recess and is fitted with a predetermined fit tolerance so that a predetermined frictional force is generated therebetween. In this configuration, when the inner diameter adjusting member is rotated in the accommodating recess, the thread insertion hole communicates with the thread through hole desired by the angler. That is, the inner diameter of the through hole communicating with the thread insertion hole is adjusted. In this case, since a predetermined frictional force is generated between the inner diameter adjusting member and the housing recess, the inner diameter adjusting member does not rotate unless the angler intentionally rotates. Therefore, the inner diameter of the through hole is not inadvertently changed by the angler.

  Further, the posture changing mechanism is formed such that the inner diameter adjusting member is formed in a polyhedron shape, and the inner wall surface shape of the housing recess surrounds and holds the inner diameter adjusting member. This is realized by a structure that is detachably fitted in the housing recess. In this configuration, the angler pulls out the inner diameter adjusting member from the accommodating recess, changes the direction of the member, and fits it again into the accommodating recess, so that what the angler desires among the plurality of through holes and the thread insertion hole can be obtained. Communicate. That is, the inner diameter of the through hole communicating with the thread insertion hole is adjusted. In this case, the inner diameter adjusting member is formed in a polyhedron shape, and the housing recess is formed in an inner wall surface shape corresponding to the polyhedron shape. Therefore, the inner diameter adjusting member is positioned in the housing recess. Therefore, unless the angler intentionally inserts and removes the inner diameter adjusting member, the inner diameter of the through hole does not change.

  As described above, according to the present invention, by changing the inner diameter of the thread insertion hole through which the fishing line is inserted, the mode of the device can be freely changed between full play and half play. In addition, when the mode of the device is changed, it is not necessary to replace the fishing float or to attach or detach the float, so that the angler can easily and quickly change the mode of the device.

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

FIG. 1 is a partial cross-sectional exploded view of a fishing float (hereinafter simply referred to as “float”) 20 according to a first embodiment of the present invention.
The float 20 is of a so-called centering type, and is used, for example, for fishing on a flounder. The float 20 includes a floating body 22 provided with a thread insertion hole 21 and an inner diameter adjusting member 23 for adjusting the inner diameter of the thread insertion hole 21.

  The feature of this embodiment is that the inner diameter adjusting member 23 can change its posture with respect to the floating main body 22 via a posture changing mechanism 27 described in detail later. Three through holes 24, 25, and 26 having different inner diameters are provided, and by changing the posture of the inner diameter adjusting member 23, each of the through holes 24 to 26 selectively communicates with the thread insertion hole 21. In this way, the inner diameter of the thread insertion hole 21 through which the fishing line is inserted is expanded and contracted.

  The floating body 22 is made of, for example, wood or resin, and is formed in a substantially spindle shape in the present embodiment. However, the outer shape of the floating body 22 is not limited to such a spindle shape, and various shapes such as a conical shape can be adopted. The floating body 22 is formed with holes 32 and 33 penetrating along the central axis in the longitudinal direction. The inner diameters of these holes 32 and 33 are different, and as shown in the figure, the large-diameter hole 33 is provided so as to be continuous with the small-diameter hole 32.

  A sleeve 28 is fitted in the hole 32. The sleeve 28 is made of resin, metal or the like, and is formed in a cylindrical shape. The outer diameter of the sleeve 28 corresponds to the inner diameter of the hole 32, and the sleeve 28 is fitted into the floating body 22 without any gap. The sleeve 28 is provided for the purpose of smoothly inserting the fishing line, but the sleeve 28 may be omitted.

  A buoyancy adjusting weight 29 is fitted in the hole 33. The buoyancy adjustment weight 29 is made of a metal having a relatively large specific gravity, such as brass, lead, or tungsten alloy, and is formed in a substantially disk shape. The buoyancy adjusting weight 29 is provided with a square hole 30 along its thickness direction (vertical direction in the figure). A space 31 (accommodating recess) is defined by the inner wall surface of the buoyancy adjusting weight 29 fitted in the hole 33 (that is, the inner wall surface of the hole 30). The space 31 is formed in a cubic shape with the dimension of each side being a. Therefore, the thread insertion hole 21 through which the fishing line is inserted is formed by the internal space of the sleeve 28 and the space 31, and the inner diameter adjusting member 23 is fitted in the space 31.

  The inner diameter adjusting member 23 is made of resin, wood, metal, or the like, and is formed in a cube whose one side is a. However, the dimension of each side of the inner diameter adjusting member 23 and the dimension of the wall surface defining the space 31 are set to have a predetermined fit tolerance. Therefore, the inner diameter adjusting member 23 is detachably fitted in the space 31, but a constant frictional force is generated between the two in the fitted state. As a result, the inner diameter adjusting member 23 is held on the floating main body 22 by a constant amount. It is designed to be held by force. That is, the posture changing mechanism 27 is configured by the inner wall surface shape of the space 31 corresponding to the outer shape of the inner diameter adjusting member 23, whereby the inner diameter adjusting member 23 is oriented with respect to the floating body 22. (Posture) can be changed.

  Specifically, by the posture changing mechanism 27, the inner diameter adjustment member 23 can take a posture in which any one of the through holes 24 to 26 communicates with the thread insertion hole 21. . In other words, the through holes 24 to 26 communicating with the thread insertion hole 21 are changed by the posture changing mechanism 27, which means that the inner diameter of the thread insertion hole 21 is changed. Therefore, the posture changing mechanism 27 functions as an inner diameter adjusting mechanism that adjusts the inner diameter of the thread insertion hole 21.

  The inner diameter adjusting member 23 is provided with the three through holes 24 to 26. Each of the through holes 24 to 26 penetrates between the circumferential surfaces of the inner diameter adjusting member 23 facing each other. Moreover, although the internal diameter dimension of each through-hole 24-26 can be set suitably, in this embodiment, the internal-diameter dimension of the through-hole 24 is set to 1.0 mm-1.2 mm, and the internal diameter of the through-hole 25 is set. The dimension is set to 1.5 mm to 2.0 mm, and the inner diameter dimension of the through hole 26 is set to 2.0 mm to 2.5 mm. However, the inner diameter of the through holes 24 to 26 is not limited to this. The inner diameters of the through holes 24 to 26 are different from each other, as will be described later, to determine whether or not the floating device provided on the fishing line can be inserted.

  2 and 3 are sectional views of the float 20 and show a state in which the float 20 is used for a fishing device. FIG. 2 shows a state where the through hole 24 of the inner diameter adjusting member 23 is communicated with the thread insertion hole 21, and FIG. 3 shows a state where the through hole 26 of the inner diameter adjustment member 23 is communicated with the thread insertion hole 21. Yes.

  As shown in FIG. 2, in the state where the through hole 24 communicates with the thread insertion hole 21, the fishing line 35 is inserted into the thread insertion hole 21, but when the fishing line 25 slides relative to the float 20, A float 34 provided on the fishing line 35 contacts the inner diameter adjusting member 23. At this time, since the inner diameter dimension of the through hole 24 of the inner diameter adjusting member 23 is small, the float 34 cannot pass through the through hole 24. Therefore, the device is a semi-floating type.

  Further, the angler can remove the inner diameter adjusting member 23 from the floating body 22 from this state. Specifically, the angler inserts, for example, an elongated rod from above the thread insertion hole 21 and pushes the inner diameter adjusting member 23 downward. As a result, the inner diameter adjusting member 23 is detached from the space 31. Then, the angler changes the orientation of the inner diameter adjusting member 23 (changes the posture), and fits again into the space 31 so that the through hole 26 communicates with the thread insertion hole 21. Thereby, as shown in FIG. 3, the thread insertion hole 21 and the through hole 26 communicate with each other. However, since the inner diameter of the through hole 26 is set large, the float 34 is inserted through the through hole 26. be able to. Therefore, the device is a full floating type.

  As described above, in the float 20 according to the present embodiment, the posture of the inner diameter adjusting member 23 is changed via the posture changing mechanism 27 and the inner diameter of the thread insertion hole 21 is changed. However, it can be properly used for an aspect in which the thread insertion hole 21 can be inserted and an aspect in which the thread insertion hole 21 cannot be inserted. In other words, the fishing device can be selectively used for the semi-floating type and the full floating type by the single float 20, and the mechanism can be easily and quickly changed without requiring the attachment / detachment work of the floating device 34. Is called.

  In particular, in the present embodiment, the posture changing mechanism 27 is configured such that the inner diameter adjusting member 23 is formed in a cube shape, and the inner wall surface shape constituting the space 31 is determined correspondingly. Therefore, the structure of the posture changing mechanism 27 is very simple. Therefore, the structure of the float 20 is not particularly complicated, and the angler simply pulls out the inner diameter adjusting member 23 from the space 31, changes its direction, and fits it into the space 31 again. There is an advantage that the inner diameter can be changed.

  In the present embodiment, the inner diameter adjustment member 23 is formed in a cubic shape, but is not limited to this shape, and the inner diameter adjustment member 23 is formed in a polyhedron (preferably regular polyhedron) shape. Also good. In this case, it is preferable that the space in which the inner diameter adjusting member is held is also changed corresponding to the outer shape of the inner diameter adjusting member. In short, if the outer shape of the inner diameter adjusting member 23 is a polyhedral shape, the inner diameter adjusting member 23 can be positioned in the space 31 that accommodates it, so that the posture adjustment of the inner diameter adjusting member 23 is realized and the posture change is allowed. In the present embodiment, the inner diameter adjusting member 23 is disposed below the thread insertion hole 21 (lower part of the main body 22), but may be disposed above the thread insertion hole 21 (upper part of the main body 22). Of course it is good.

Next, a modified example of this embodiment will be described.
FIG. 4 is a cross-sectional view of a float 40 according to a first modification of the present embodiment.

  The difference between the float 40 according to this modified example and the float 20 according to the above embodiment is that in the float 20, the angler uses an elongated rod or the like when changing the posture of the inner diameter adjusting member 23. In the floating 40 according to the above, the angler can grip the inner diameter adjusting member 23 by hand. The other configuration is the same as that of the float 20 described above.

  Specifically, the depth dimension of the space 41 into which the inner diameter adjusting member 23 is fitted is set to be smaller than the dimension a of each side of the inner diameter adjusting member 41. As a result, the inner diameter adjustment member 23 fitted in the space 41 has a lower portion 42 that protrudes from the main body 22. Since the angler can hold the protruding portion, the posture of the inner diameter adjusting member 23 can be changed more easily. As a result, the mode of the device can be changed more easily and quickly. In order for the angler to grip the inner diameter adjusting member 23 more reliably, the inner diameter adjusting member 23 may be provided with a knob such as a protrusion.

FIG. 5 is a partial cross-sectional exploded view of a float 50 according to a second modification of the present embodiment.
The float 50 according to this modified example is different from the float 20 according to the above embodiment in that the float 20 is provided with the buoyancy adjustment weight 26 for adjusting the buoyancy of the float 20, but this modification In the float 50 according to the example, the inner diameter adjusting member 51 is made of a metal having a relatively large specific gravity such as lead or tungsten alloy, and also serves as a buoyancy adjusting weight. The other configuration is the same as that of the float 20 described above.

  As described above, the inner diameter adjusting member 51 also serves as a buoyancy adjusting weight, so that the structure of the float 50 is further simplified. Thereby, there exists an advantage that the manufacturing cost of the float 50 can be reduced further. Of course, in this modified example, a structure that allows the angler to grip the inner diameter adjusting member 51 can be adopted as in the first modified example.

<Second Embodiment>
Next, a second embodiment of the present invention will be described.
FIG. 6 is a partial cross-sectional exploded view of a float 60 according to the second embodiment of the present invention.

  The difference between the float 60 according to this embodiment and the float 20 according to the above embodiment is the structure of the inner diameter adjusting member 61 and the structure of the posture changing mechanism 62 that allows the posture change of the inner diameter adjusting member 61. In addition, about another structure, it is the same as that of the float 20 which concerns on the said embodiment.

  Specifically, the inner diameter adjusting member 61 is made of, for example, resin and is formed in a cylindrical shape. The inner diameter adjusting member 61 is provided with through holes 63 and 64 along a direction orthogonal to the axial direction N (that is, a radial direction). In the present embodiment, the inner diameter of the through hole 63 is small, and the above-described buoyant tool 34 (see FIG. 2) cannot be inserted through the through hole 63. Further, the inner dimension of the through hole 64 is set to be large so that the float 34 can be inserted. In the present embodiment, the through hole 63 and the through hole 64 are provided so as to intersect with each other at an angle θ (for example, 90 °). Of course, in addition to these through holes 63 and 64, other through holes having different inner diameters may be provided.

  On the other hand, a space 65 into which the inner diameter adjusting member 61 is fitted is provided on the floating body 22 side. The space 65 is partitioned by the inner wall surface of the buoyancy adjusting weight 26 and is formed in a substantially cylindrical shape corresponding to the outer shape of the inner diameter adjusting member 61. At this time, a predetermined fit tolerance is set between the dimension of the inner wall surface defining the space 65 and the outer dimension of the inner diameter adjusting member 61. Therefore, as in the first embodiment, the inner diameter adjusting member 61 is fitted in the space 65 and generates a predetermined frictional force with the floating body 22. , It is held with a predetermined holding force. The inner diameter adjusting member 61 is fitted into the space 65 such that the axial direction N is along the direction orthogonal to the longitudinal direction of the thread insertion hole 21. Accordingly, if the angler rubs the lower surface portion of the floating main body 22 by hand, the inner diameter adjusting member 61 can be rotated about the axial direction N as a center of rotation, and the desired one of the through holes 63 and 64 can be rotated. One of these can communicate with the thread insertion hole 21.

  As described above, in the float 60 according to the present embodiment, the inner diameter adjusting member 61 is rotated in the space 65, so that the fisherman desires the through holes 63 and 64 having different inner diameters and the thread insertion hole 21. As a result, the inner diameter of the thread insertion hole 21 is adjusted. In addition, in this case, since a predetermined frictional force is generated between the inner diameter adjusting member 61 and the space 65, the inner diameter adjusting member 61 does not rotate unless the angler intentionally rotates. Therefore, in actual fishing, the angler can freely change the mode of the device to the semi-floating type or the full floating type without requiring the work of attaching and detaching the float 34.

Moreover, FIG. 7 is sectional drawing of the float 60 which concerns on the modification of this embodiment.
In the float 60 according to this modified example, locking projections 66 are provided on both end surfaces of the inner diameter adjusting member 61. An engagement recess 67 is provided on the opposite wall surface of the buoyancy adjustment weight 26, and the locking projection 66 is fitted in the engagement recess 67 in a state where the inner diameter adjustment member 61 is fitted in the space 65. . The locking protrusion 66 is formed in, for example, a hemispherical shape, and the engaging concave portion 67 has an inner wall surface formed in a hemispherical shape corresponding to the shape of the locking protrusion 66.

  In this modification, since the locking projection 66 is fitted into the engagement recess 67 in a state where the inner diameter adjustment member 61 is fitted in the space 65, the inner diameter adjustment member 61 is more reliably positioned on the floating body 22. Is done. For this reason, the inner diameter adjusting member 61 is formed in a cylindrical shape, which may cause the inner diameter adjusting member 61 to rotate unintended by the fisherman in actual fishing. However, the locking protrusion 66 and the engaging recess 67 are provided. By doing so, there is an advantage that the rotation of the inner diameter adjusting member 61 is surely prevented.

  The present invention can be applied to floats used during fishing.
