Hereinafter, the metal underwater float (hereinafter referred to as “underwater float”) and the mounting structure of the underwater float according to the embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing an example of a fishing tackle (hereinafter referred to as a tackle) 100 using the underwater float 10 according to the present embodiment.
The device 100 is configured by tying a float 102 to a fishing line 101 and inserting the float 101 into a shimori ball 103, a hollow float 104 as a hit float, and an underwater float 10, respectively. The device 100 is a so-called floating device, and the center float 104 and the underwater float 10 can move along the road thread 101 within a predetermined range. Further, Harris 106 is bound to the tip of the line 101 via a so-called Sarkhan 105. A fishing hook 107 is provided at the tip of the Harris 106, and a gun ball 108 is attached at an appropriate position on the way.

FIG. 2 is a diagram showing an example of an underwater float mounting structure. In each drawing including FIG. 2, the upper side is shown as the upper side and the lower side is shown as the lower side as appropriate for the sake of easiness of explanation.
The underwater float mounting structure of the present embodiment includes an underwater float 10, a pipe member 20, and a pair of fixing pipe members 30. The pipe member 20 is positioned in a state of being inserted into the underwater float 10, and a pair of fixing pipe members 30 are positioned in a state of being coupled to both ends of the pipe member 20.

First, the underwater float 10 will be described.
FIG. 3 is a diagram showing an example of the configuration of the underwater float 10. 3 (a) is a plan view of the underwater float 10, FIG. 3 (b) is a front view of the underwater float 10, and FIG. 3 (c) is a cross-sectional view taken along the line I-I of the underwater float 10.
The underwater float 10 functions to submerge the device 100 in water. The underwater float 10 is made of metal, and for example, a metal such as lead or brass, a non-ferrous metal, or the like can be used. Further, the underwater float 10 has a long spherical shape or an oblong shape that is long in the vertical direction. The underwater float 10 has a shape in which the radius of curvature of the outer peripheral surface is smaller on the lower side than on the upper side and the center of gravity is biased downward, and the lower end of the water float 10 sinks in a posture facing the bottom side in water. The vertical length La of the underwater float 10 is shorter than the vertical length Lb of the pipe member 20, which will be described later.

Further, the underwater float 10 has an upper end and a lower end open inside, and has an insertion hole 11 along the vertical direction. The insertion hole 11 is a hole into which the pipe member 20 is inserted. The length of the insertion hole 11 along the axial direction is the same as the vertical length La of the underwater float 10. Further, the insertion hole 11 has an inner diameter da larger than the outer diameter Db described later of the pipe member 20. The insertion hole 11 is formed with a large diameter portion 12 having an inner diameter da larger than that of the lower end side on the upper end side. The large diameter portion 12 is formed from the upper end of the insertion hole 11 to a predetermined range, specifically, approximately 1/3 of the length La of the insertion hole 11. The large diameter portion 12 is a portion into which a part of the fixing pipe member 30 is inserted.

Further, the underwater float 10 has a split groove 13 that communicates the insertion hole 11 with the outside of the underwater float 10. The split groove 13 communicates the insertion hole 11 and the outside in a direction orthogonal to the axial direction of the insertion hole 11. The split groove 13 extends from the upper end to the lower end of the underwater float 10. Therefore, when the underwater float 10 is viewed from the vertical direction as shown in FIG. 3A, the split groove 13 has a groove shape as if it were dug from the outer peripheral surface of the underwater float 10 toward the center side. Further, the groove width W along the horizontal direction of the split groove 13 is smaller than the inner diameter da of the insertion hole 11. Further, the groove width W along the horizontal direction of the split groove 13 is smaller than the outer diameter Db of the pipe member 20. In this way, by having the split groove 13 that allows the insertion hole 11 and the outside of the underwater float 10 to communicate with each other, the path thread 101 can be inserted into the split groove 13 later without having to insert the path thread 101 into the insertion hole 11 in advance. It can be inserted into the insertion hole 11 through.

Next, the pipe member 20 will be described.
FIG. 4 is a diagram showing an example of the configuration of the pipe member 20. FIG. 4A is a plan view of the pipe member 20, and FIG. 4B is a front view of the pipe member 20.
The road thread 101 is movably inserted into the pipe member 20. Further, the pipe member 20 is inserted into the insertion hole 11 of the underwater float 10. The tube member 20 is made of a flexible synthetic resin, and for example, polypropylene (PP), acrylonitrile-butadiene-styrene copolymer (ABS), or the like can be used. The tube member 20 has a tubular shape that is long in the vertical direction. The vertical length Lb of the pipe member 20 is longer than the vertical length La of the underwater float 10. In other words, the length Lb of the pipe member 20 in the vertical direction is longer than the length of the insertion hole 11 of the underwater float 10 in the vertical direction. Further, the pipe member 20 has an outer diameter Db smaller than the inner diameter da of the insertion hole 11 of the underwater float 10 and larger than the groove width W of the split groove 13 of the underwater float 10. As described above, since the outer diameter Db of the pipe member 20 is larger than the groove width W of the split groove 13 of the underwater float 10, the pipe member 20 is inserted into the insertion hole 11 of the underwater float 10 through the split groove 13 and vice versa. It cannot be pulled out from the insertion hole 11, and can be inserted into or pulled out from the insertion hole 11 through the opening at the upper end or the lower end of the insertion hole 11.
Further, the pipe member 20 has an insertion hole 21 inside along the vertical direction. The insertion hole 21 is inserted so that the thread can be moved.

Next, the fixing pipe member 30 will be described.
5 (a) is a plan view of the fixing pipe member 30, FIG. 5 (b) is a front view of the fixing pipe member 30, and FIG. 5 (c) is a line II-II of the fixing pipe member 30. It is a cross-sectional view.
The fixing pipe member 30 is coupled to the end portion of the pipe member 20 inserted into the insertion hole 11 of the underwater float 10 that protrudes from the insertion hole 11. The fixing tube member 30 is a rubber material having elasticity and elasticity, and for example, ethylene propylene diene rubber (EPDM), silicone, or the like can be used. The fixing tube member 30 is substantially tubular, and has, for example, a shape in which a substantially rhombus or a substantially truncated cone shape is vertically and vertically superposed when viewed from the front. The length Lc of the fixing pipe member 30 in the vertical direction is preferably longer than the length divided into two by subtracting the vertical length Lb of the pipe member 20 from the vertical length La of the underwater float 10. .. That is, it is preferable that the relationship is length Lc> (length La-length Lb) / 2.

Further, in the fixing pipe member 30, the largest outer diameter Dc is larger than the inner diameter da of the insertion hole 11 of the underwater float 10. Further, the fixing pipe member 30 has an insertion hole 31 inside along the vertical direction. The insertion hole 31 is inserted so that the thread can be moved. Further, in the insertion hole 31, the inner diameters de of the upper end and the lower end are substantially the same as the outer diameter Db of the pipe member 20, or smaller than the outer diameter Db of the pipe member 20. By press-fitting the end portion of the pipe member 20 into the insertion hole 31 of the fixing pipe member 30, the fixing pipe member 30 is coupled to the end portion of the pipe member 20. In a state where the fixing pipe member 30 is connected to the end portion of the pipe member 20, the inner peripheral surface of the insertion hole 31 and the outer peripheral surface of the pipe member 20 are brought into close contact with each other due to the elasticity of the fixing pipe member 30.

Next, a method of attaching the underwater float 10 to the road thread 101 will be described with reference to FIGS. 6 and 7. 6 and 7 are cross-sectional views for explaining a method of attaching and detaching the underwater float 10 to and from the road thread 101.
First, the user inserts the thread 101 into the insertion hole 31 of the pair of fixing pipe members 30 and the insertion hole 21 of the pipe member 20 in advance so as to be located between the center float 104 and the sarkhan 105. .. At this time, the thread 101 is sequentially inserted so that the pipe member 20 is located between the pair of fixing pipe members 30.

Next, as shown in FIG. 6A, the user positions the underwater float 10 at a position between the fixing pipe member 30 and the pipe member 20 on one side with respect to the road thread 101. Next, the thread 101 is inserted into the insertion hole 11 through the split groove 13 of the underwater float 10.

Next, the user gradually brings the underwater float 10 and the pipe member 20 closer to each other while maintaining the state in which the thread 101 is inserted into the insertion hole 11 of the underwater float 10. As shown in FIG. 6B, the user inserts the pipe member 20 into the insertion hole 11 through the opening on one side (upper end in FIG. 6B) of the insertion hole 11 of the underwater float 10. The user arranges the underwater float 10 so as to be located substantially at the center of the pipe member 20 in the vertical direction. As described above, since the length Lb of the pipe member 20 is longer than the length La of the underwater float 10, both ends of the pipe member 20 project from the upper end opening and the lower end opening of the insertion hole 11 of the underwater float 10. ..

Next, the user gradually brings the pair of fixing pipe members 30 and the pipe member 20 closer to each other. As shown in FIG. 7, the user inserts the end of the pipe member 20 protruding from the opening at the upper end of the insertion hole 11 of the underwater float 10 so as to press-fit it into the insertion hole 31 of the upper fixing pipe member 30. Further, the end portion of the pipe member 20 protruding from the opening at the lower end of the insertion hole 11 of the underwater float 10 is inserted so as to be press-fitted into the insertion hole 31 of the lower fixing pipe member 30. Therefore, the pair of fixing pipe members 30 are connected to both ends of the pipe member 20. As described above, the largest outer diameter Dc of each of the pair of fixing pipe members 30 is larger than the inner diameter da of the insertion hole 11 of the underwater float 10. Therefore, even if the pipe member 20 tries to slip along the insertion hole 11 of the underwater float 10, the fixing pipe member 30 can interfere with the underwater float 10 and prevent the pipe member 20 from slipping through. You can connect. Since the road thread 101 is inserted through the pipe member 20, the underwater float 10 is substantially attached (attached) to the road thread 101 by connecting the underwater float 10 to the pipe member 20. Can be done. According to such an underwater float mounting structure, the underwater float 10 is integrated with the pipe member 20 and the pair of fixing pipe members 30 to sink in the water along the thread 101, so that the speed desired by the user is achieved. The device can be submerged in water.

Further, as shown in FIG. 7, the lower end of the upper fixing pipe member 30 is inserted into the large diameter portion 12 of the insertion hole 11 of the underwater float 10. By inserting a part of the fixing pipe member 30 into the insertion hole 11 of the underwater float 10 in this way, the fixing pipe member 30 and the underwater float 10 are brought into close contact with each other. It is possible to prevent unintentional movement along the inside of the insertion hole 11.

Further, in general, cushions are provided on the upper side and the lower side of the underwater float 10 so that the underwater float 10 does not damage other members when the underwater float 10 moves along the road thread 101. It is attached by inserting it through 101. The cushion absorbs the impact when the underwater float 10 comes into contact with the other member by interposing between the cushion and the other member when the underwater float 10 moves along the road thread 101.
On the other hand, as shown in FIG. 7, in the present embodiment, the upper end of the upper fixing pipe member 30 is located so as to protrude from the upper end of the pipe member 20, and the lower end of the lower fixing pipe member 30 is located. Is located so as to protrude from the lower end of the pipe member 20. Therefore, even if the underwater float 10 moves along the thread 101, it is not necessary to attach a cushion because the elastic fixing pipe member 30 comes into contact with other members, so that the cushion is omitted from the mechanism. can do.

Next, the user wants to remove the currently attached underwater float 10 from the road thread 101 in order to replace it with a different size underwater float 10. In this case, the user can remove (remove) the underwater float 10 without cutting the road thread 101 by performing the reverse procedure of the method of attaching the underwater float 10 to the road thread 101.
However, the user does not need to remove both of the pair of fixing pipe members 30 from the pipe member 20, and only one of the pair of fixing pipe members 30 for fixing is removed from the end of the pipe member 20. You may remove it. In this case, the pipe member 20 is pulled out from the other fixing pipe member 30 side along the insertion hole 11 of the underwater float 10, and the thread 101 is separated from the insertion hole 11 of the underwater float 10 through the split groove 13 to float underwater. 10 can be removed from the thread 101.

As described above, in the underwater float 10 of the present embodiment, the insertion hole 11 into which the pipe member 20 through which the thread 101 is inserted is inserted, and the insertion hole 11 and the outside are orthogonal to the axial direction of the insertion hole 11. It has a split groove 13 that communicates with the split groove 13. The length La of the insertion hole 11 along the axial direction is shorter than the length Lb of the pipe member 20, and the groove width W of the split groove 13 is smaller than the outer diameter Db of the pipe member 20. Therefore, since the pipe member 20 cannot be inserted into or pulled out from the insertion hole 11 of the underwater float 10 through the split groove 13, the fixing pipe member 30 can be connected to the end portion of the pipe member 20. The underwater float 10 can be easily attached to and detached from the thread 101 by removing it from the end portion.

Although the present invention has been described above with respect to the above-described embodiment, the present invention is not limited to the above-described embodiment, and changes and the like can be made within the scope of the present invention.
In the above-described embodiment, the materials, shapes, and sizes of the underwater float 10, the pipe member 20, and the fixing pipe member 30 have been specifically described, but the materials, shapes, and sizes are not limited to those described above. , Can be changed. It is preferable to prepare a plurality of types of the underwater float 10 having different sizes. In this case, it is preferable that the inner diameter da of the insertion hole 11 is substantially the same for any of the underwater floats 10, and any of the underwater floats 10 is divided. It is preferable that the groove width W of the groove 13 is substantially the same.

In the above-described embodiment, the case where both ends of the pipe member 20 protrude from the upper end opening and the lower end opening of the insertion hole 11 of the underwater float 10 has been described, but the case is not limited to this case. For example, by reducing the diameter of the opening on one side of the insertion hole 11 or providing a stopper on the opening on one side of the insertion hole 11 within a range that does not interfere with the thread 101, the other end of the pipe member 20 Only may be configured to project from the opening on the other side of the insertion hole 11 of the underwater float 10. In this case, since it is sufficient to connect one fixing pipe member 30 only to the other end of the pipe member 20 that protrudes from the insertion hole 11 of the underwater float 10, the number of parts of the underwater float mounting structure is reduced. be able to.
