Field of the Invention The present invention relates to a float for fishing fish, and more particularly to a float having variable buoyancy. 2. Description of the Related Art Conventionally, in the case of fishing fish, the type of fish mainly located in the middle layer of the water depth is a swimming layer, so-called, depending on the season, time, sunshine, water temperature, tidal current, strength of waves and the like at the time of fishing. "
The "shelf" changes, and you need to bring bait to the shelf to catch it, so you can't expect much of the results. Generally, the tricks for catching fish in this middle class are on the water surface attached to the middle of the fishing line. The floating float is attached with a weight underneath, and a hook is tied under it to feed the bait, but in this method, the bait reaches a certain depth under the float, thus delivering the bait to an invisible fish shelf [0003] Therefore, in recent fishing techniques, the float and the device are gradually lowered together by using a spherical float, a so-called "conical float". The so-called “submergence fishing,” which uses bait to reach the so-called “shelves” of the swimming layer of fish, is effective because it is possible to search the shelves with fish widely, and sinks the baits at a sedimentation speed close to nature. It also makes the fish vigilant However, in order to gradually sink the device, it takes time to select the float with the optimal buoyancy and adjust the size of the weight of the device to balance the weight of the device and the float. In addition, this balance slightly changes each time depending on the salt concentration of seawater, temperature, tide, amount of fishing line in the water, etc., so it is adjusted every time fishing goes. [0004] In the case of a conical float, a so-called "through hole float" as shown in Fig. 4 is often used to form a through hole in the upper and lower centers and pass a fishing line. There is a float with a ring that makes a hole in the lateral direction and lets the fishing line pass through it, but it is often used because the inside float has a sense of unity with the fishing line, the feel when moving the rod tip is good, etc. Problems to be solved by the invention With the configuration of the conventional through float, it took time to select the float and adjust the size of the weight of the device to obtain the optimal buoyancy by balancing the weight of the device and the condition of the float and seawater. If this balance is not balanced, the bait will pass the shelf too quickly if the device is relatively heavy, and on the contrary, it will not sink and reach the shelf as if the floater's buoyancy is too large. Ideally, the fishing line between the bait and the float should sink substantially linearly and gradually sink.For this reason, conventionally, multiple floats with different buoyancy have been prepared and replaced according to the situation.
Or, the size of the weight was changed and adjusted. This balance changes every time you go fishing, depending on the salinity of seawater, temperature, tide, the amount of fishing line in the water, and it takes time and effort to adjust,
Moreover, it is necessary to prepare various plural floats and weights, which is complicated. An object of the present invention is to provide a means for solving the above-mentioned problem by making it possible to continuously and finely adjust the balance between the float and the device with respect to the through float by one touch with one float. In order to solve this problem, the present invention has a structure in which a float is divided into an upper portion and a lower portion, and both portions are hermetically sealed to form a single float. However, if the degree of fitting is changed, the volume of the whole float changes. The buoyancy of the float at this time is determined by the volume of the float, its own weight, and the specific gravity of seawater. Therefore, if the volume changes, the buoyancy naturally changes. In order to change the degree of fitting, the upper and lower parts are screwed together and the upper or lower part is rotated to continuously change the volume and finely adjust the buoyancy. The floating float for fishing fish of the present invention, particularly the through-hole float, has hermetically sealed sliding fitting points (hereinafter referred to as fitting points) on the outer periphery and inner periphery of the float in order to prevent seawater from entering the inside of the float from the fitting location. It is characterized by having been provided. The degree of fitting is changed by the degree of screwing of a pair of screws provided on the upper and lower parts, and a separately provided fitting part has a sealed fitting structure that can slide so that water does not enter inside. Take. The "sealed fitting point on the outer circumference" is to change the degree of fitting to change the volume and adjust the buoyancy, and the "sealed fitting point on the inner circumference" is to seal the thin tube through which the fishing line for the inside passes. It is made to slide. With the structure that continuously changes the buoyancy of the same float,
It is possible to easily adjust the balance according to various situations, and it is possible to sufficiently search the shelves and expect to improve fishing results. In addition, it is easy to settle the bait at a speed close to nature depending on the situation. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a fishing float according to the present invention. 3 and 4 are diagrams of a conventional mechanism used for explaining the present invention using a conical float. Figure 1,
2, 7 and 8 are views of conical floats for fishing fish according to the present invention.
FIGS. 5 and 6 show known floats with buoyancy adjusting rings. First, the entirety of a general device referred to as fishing in the air or fishing in the upper class will be described with reference to FIG. A float 6 is passed through a fishing line 5 from a reel 2 attached to a fishing rod 1 through a guide 3, and a weight 7 and a fishing hook 8 are ahead of the float 6. In the above-mentioned "sinking fishing", it is necessary that the device below the float is substantially straight and gradually sinks. The float 6 is a so-called "through float", and as shown in FIG. 4, the fishing line 4 can slide through a small hole 6a5 penetrating the center, and when the mechanism sinks, the float remains floating in the water. The fishing line slides to the float stopper 4. When the device sinks further, the float and the device start to sink together. At this time, the sinking speed is determined by the buoyancy of the float, the weight of the device in the water other than the float, the density of the water, the tide, and the like. Therefore, to adjust this speed optimally, it is common to replace the float or change the weight. The present invention relates to the float 6 shown in FIG. FIG. 2 is an external view of the float 6 according to the present invention as viewed from the side. If the top (upper) 6a and the bottom (lower) 6b of the float 6 are closely fitted and sealed so that seawater does not enter from the fitting portion, and if the gap 6c can expand and contract, the volume of the float 6 as a whole increases or decreases, but the weight is reduced. Since it is constant, buoyancy will increase or decrease as a result. FIG. 7 is a sectional view of the top 6a of the float according to the present invention. The head 6a1 has a density (specific gravity) of 1 such as paulownia or balsa wood.
It is composed of the following light members and mainly generates buoyancy. The top cylindrical portion 6a3 is made of relatively light and strong metal aluminum or the like, and a thin groove is formed on the cylinder to fit an O-ring 6a4 made of rubber or the like. Male screw 6a2 having a through hole at the center
Is inserted from below into the center of the circumference of the head 6a1 of the top 6a of the float 6 and fixed. A through hole 6a5 is formed in the head 6a1 on the extension of the through hole of the male screw 6a2. The male screw is cut in the middle of the male screw 6a2, and a thin tube 6a6 is provided at the lower end. FIG. 8 is a sectional view of the bottom 6b of the present invention. The cup 6b1 is made of a material such as light metal, such as aluminum, having a relatively higher specific gravity than the top 6a, or a high-strength plastic, etc., in order to keep the center of gravity of the whole float below. The cup 6b1 has a cylindrical cavity 6b4 at the upper inner periphery and a cut groove 6b5 opposing the O-ring 6a4 of the top 6a. The female screw 6b2 is inserted and fixed below the bottom 6b. In addition, the female screw 6b2 is made of a metal having a high density or the like, and also has a function of holding the center of gravity of the entire float 6 below. The female screw 6b2 is provided with a female screw which is screwed with the male screw 6a2, and further has a hole 6b6 for vertically passing the thin tube 6a6 of the top 6a. A hollow having a large diameter is provided in the middle of the hole, and the O-ring 6b3 is fitted. Put in. FIG. 1 is a sectional view showing a combination of a top 6a and a bottom 6b of a float according to the present invention. The kerf 6b5 of the cylindrical cavity 6b4 at the top of the bottom fits tightly with the O-ring 6a4 wound around the circumference of the top cylindrical portion 6a3 of the top 6a, forming an "outer peripheral hermetically-sealed portion". Similarly, an intermediate portion of the male screw 6a2 is screwed into the female screw 6b2, and at the same time, the thin tube 6a6 below the male screw is closely fitted to the O-ring 6b3, thereby forming an "inner-peripheral hermetically sealed fitting portion". It is made to prevent water from entering. In order to adjust the degree of fitting, the female screw 6b2 provided on the bottom 6b and the male screw 6a2 provided on the top 6a are screwed together, and the top 6a and the bottom 6b of the float 6 are grasped with both hands and rotated in the opposite direction to rotate the float. The top 6a and the bottom 6b of 6 are separated from each other. As a result, the volume of the whole float increases and decreases, and buoyancy can be adjusted. According to the float for fishing fish of the present invention, the volume of the float as a whole is increased or decreased and the buoyancy can be adjusted by simply rotating the float while the float is passed through the fishing line. In the float for fishing fish of the present invention, the buoyancy can be continuously adjusted by one float, so that it is possible to easily and delicately adjust the balance with the device according to the state of seawater, and to search for fish shelves. Yes, you can expect better fishing results. If the buoyancy is adjusted to be as large as necessary and sufficient as compared with the device, it is possible to keep the float floating with the same float and to fish a certain shelf with the optimal buoyancy. If the screw is removed and a proper weight is inserted into the float and the buoyancy is adjusted accordingly, the weight of the float and the entire device becomes heavy, and the float can be thrown farther.
