[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing tackle, and more particularly to a mid-through tack (including underwater tacks) whose sinking force or buoyancy can be adjusted.

[0002]

2. Description of the Related Art Of the conventional medium-sized floats, the underwater floats that are used in water usually consist of black beds, and they are used as a weight when submerged in water and used as a tackle, as well as in the sea. It had the function of harmonizing the movement of the mechanism introduced into the ocean current. Further, the underwater plow functions as a weight against the fishing plow having buoyancy provided on the upper part thereof, and therefore, in the same product to be mass-produced, it is necessary to make the sinking force constant. Furthermore, when the buoyancy-supporting bobbin provided on the upper part is changed, it is necessary to adjust the weight on the lower part, but depending on the case, it is also replaced with a submersible bob having a different sinking force.

[0003]

[Problems to be Solved by the Invention] However, the main material for underwater spout is black wood, which is usually natural wood, and the specific gravity varies. Therefore, even if the same shape is manufactured, the sinking force is different. There is. Therefore, when manufacturing standardized products, it was done by fixing a weight of appropriately selected weight to the lower part of the body of the plow, so when manufacturing an underwater plow with a certain sinking force There is a problem that it takes a lot of effort to select the weight. Also,
Conventional underwater floats have a constant individual underwater weight, so
If you change the attached buoyancy centering plow, you may need to change the underwater plow in some cases, and if you are using a middle sized underplow, you need to cut off the device and reinstall it. Yes, it was extremely troublesome. Needless to say, such a problem is a common problem not only in underwater swimmers but also in buoyant swimers. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a through-pile with which the buoyancy or sinking force can be easily adjusted according to the angler's preference.

[0004]

According to a first aspect of the present invention, there is provided a hollow plow according to claim 1, wherein the plow body has an upper member having a threading hole penetrating from the top to the bottom, and around the lower portion of the upper member. A hollow housing having a lower member that is separably screwed, wherein a weight storage chamber that can be closed by screwing the upper member and the lower member is provided inside the lower member. A ring-shaped weight having a notch on one side and a notch for balancing on the other side is stored in the weight storage chamber.

[0005]

According to the first aspect of the present invention, the bobbin main body is composed of an upper member and a lower member, a weight accommodating chamber is provided inside the lower member, and the weight in the weight accommodating chamber can be replaced. As a result, it is possible to adjust the sinking force of the through-plow. In this case, since the weight to be replaced has a ring shape in which a notch is formed on one side and a notch for balancing is formed on the other side, after separating the upper member and the lower member, the fishing line is not cut. Can be exchanged.

[0006]

Embodiments of the present invention will now be described with reference to the accompanying drawings to provide an understanding of the present invention. 1 is a cross-sectional view of a hollow plow according to a first embodiment of the present invention, FIG. 2 is a perspective view of a weight used for the hollow plow, and FIG. 3 is a second embodiment of the present invention. It is a cross-sectional view of such a centering plow.

As shown in FIG. 1, an underwater plow 10 which is an example of a hollow plow according to a first embodiment of the present invention has a plow body 11 made of a black platform divided into an upper member 12 and a lower member 13. Then, these are detachably connected by the screw portion 14. A weight storage chamber 15 formed of a circular hole is formed in the center of the lower member 13, and a plurality of ring-shaped weights 16 can be inserted therein as shown in FIG.

A cut 17 is formed on one side of the weight 16, and a notch 18 for balancing is provided on the side facing the cut 17 so as to keep the overall balance in balance. In addition, a columnar portion 19 is provided below the upper member 12.
Is provided, and a guide tube 20 made of synthetic resin or metal through which fishing line is inserted is fitted in the center. In FIG. 1, reference numerals 20a and 20b denote O-rings for sealing, and it is assumed that the upper member 12 and the lower member 13 are sufficiently waterproofed even at their joints.

Therefore, when the underwater plow 10 is used, the fishing line is passed through the guide tube 20, but when adjusting the sinking force, the upper member 12 is utilized by using the screw portion 14.
The lower member 13 and the lower member 13 are separated from each other, the weight 16 arranged in the weight storage portion 15 is taken out, and the cut 17 is used to remove it from the fishing line or to insert another weight. This allows the sinking force to be adjusted freely.

Next, an underwater plow 21 which is an example of a hollow plow according to a second embodiment of the present invention shown in FIG. 3 will be described. The same components as those of the underwater plow 10 are designated by the same reference numerals. The detailed description thereof will be omitted. In this embodiment, a weight 22 is provided at the lower end of the cylindrical portion 19 of the upper member 12, and the weight storage chamber 15 has a rubber material (which may be a spring material) which is an example of an elastic member in addition to the weight. 23 is arranged to hold down the lower weight 16. As a result, the weight 16 in the weight storage chamber 15 can be reduced, and the weight 16 housed inside does not vibrate. In FIG. 3, 23a,
Reference numeral 23b denotes an O-ring for sealing, and the peripheries of the upper member 12 and the lower member 13 are sufficiently waterproofed so that water does not enter inside.

In the above embodiment, the ring-shaped packing or the O-ring is inserted between the upper member and the lower member.
In some cases, a plate-shaped packing may be used. Also,
In the above embodiment, the specific gravity was adjusted depending on the number of used weights, but it is also possible to make the shape of each weight the same and change the specific gravity of each weight to change the overall specific gravity of the body. Yes, this allows for no internal space. In this case, the number of weights to be mounted can be one or plural. Although the above embodiments have been described with respect to the underwater skid, it is of course applicable to a middle sled having a normal buoyancy.

[0012]

According to the first aspect of the present invention, since the weight-placing chamber which can be closed inside is provided in the inner-pouch, the sinking force or the buoyancy force can be adjusted according to the manufacturer's preference or the user's preference. You can The weight stored in the weight storage chamber has a notch on one side and a notch for balancing on the other side. Therefore, when replacing the weight,
It can be done without cutting the fishing line.
