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 is at a certain depth under the float, thus delivering the bait to an invisible fish shelf [0003] In recent fishing techniques, a technique of using a spherical float, a so-called "ball float", is used to adjust the position of the float in relation to the fishing line.
There is a so-called “submergence fishing” to reach the “shelves”, which is effective for exploring the shelves with fish widely, and it also sinks the bait at a sedimentation speed that is close to nature and gives the fish a sense of caution. No effect, great effect on catch up.
However, in order to gradually sink the device, it took time to select the ball float with optimal buoyancy and adjust the size of the weight of the device in order to balance the weight of the device with the ball float. In addition, this balance slightly changes slightly each time depending on the salt concentration of seawater, temperature, tide, amount of fishing line in the water, etc., so it is adjusted each time fishing is performed, but it is often not always possible to adjust it to the optimum state. Was. [0004] In the conventional configuration, it took time to finely balance the weight of the device and the ball float and seawater. If the balance is not balanced, and the gimmicks are too heavy, the bait will pass the shelves too quickly, and conversely, the ball floats will not sink and reach the shelves as if they thought they were too buoyant. Ideally, this balance should always be maintained and the fishing line between the bait and the ball float should be straight and gradually sink. For this reason, conventionally, a plurality of ball floats having different buoyancy have been exchanged according to the holding condition or by changing the size of the weight. This balance varies depending on the salinity of seawater, the temperature, the tide, the amount of fishing line in the water, etc. every time fishing is performed, and it takes time and effort to adjust, and it is necessary to prepare various types of ball floats and weights. Met. [0005] In order to solve this problem, the present invention provides a structure in which a ball float, for example, a ball float is divided into an upper part and a lower part, and both parts are fitted to each other to form one ball float. If the degree of fitting is changed, the volume of the whole ball float changes. The buoyancy of the ball float at this time is determined by the volume of the ball 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 connected by screws provided on the upper and lower parts, respectively, and the upper and lower parts are rotated to continuously and finely adjust the buoyancy. The fishing float of the present invention has a structure in which the buoyancy of the same float is continuously changed, so that the balance can be easily adjusted even in various situations, and the shelf can be sufficiently searched. It is also easy to make the food sedimentation speed close to nature. Since the buoyancy of the float is determined by the volume of the float and its own weight and the specific gravity of seawater, the volume of the same float is varied to increase or decrease the buoyancy, and the balance between the device and the float is adjusted to be optimal. It is possible to easily adjust the buoyancy to search for fish shelves, so that fine adjustments can be easily made according to the situation, and an improvement in fishing results can be expected. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing 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 ball float. Figure 1,
2, 5, 6, 7, and 8 are diagrams of a ball float for fishing fish according to the present invention. [0008] First, the entirety of a general mechanism called "fish fishing" or "fish fishing" will be described with reference to FIG. From the reel 2 attached to the fishing rod 1 through the guide 3, the fishing line 5 and the float 6
Ahead there is a weight 7 and a fishing hook 8. In the above-mentioned "sinking fishing", it is necessary that the devices below the float are straightened and gradually sink. As shown in FIG. 4, the fishing line 4 can slide through the float 6 as shown in FIG. 4, and when the weight and the needle sink, the float floats to the float stopper 4 while floating in the water. Furthermore, when the gimmick sinks, the float and the gimmick begin to sink with a straight line. 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 come and go while being fitted and the space 6c can expand and contract, the volume of the float 6 as a whole increases or decreases, but since the weight is constant, the buoyancy increases and decreases. FIG. 5 is a sectional view of the top 6a of the float according to the present invention, and FIG. 6 is a sectional view of the bottom 6b of the present invention. The head 6a1 in FIG. 5 is made of a light member such as paulownia or balsa wood having a density (specific gravity) of 1 or less, and mainly generates buoyancy. Top cylindrical part 6
a3 is made of a relatively light and strong metal such as aluminum, has a thin groove on a cylinder, and has an O-ring 6a4 made of rubber or the like.
Fit. The male screw 6a2 of the top 6a of the float 6 is embedded and fixed in the head 6a1 of the top 6a of the float 6.
On the other hand, the cup 6b1 of the bottom 6b in FIG. 6 is made of a material such as a metal such as aluminum having a specific gravity which is relatively larger than the top 6a and has a density of 1 or more in order to keep the center of gravity of the whole float below. The cup 6b1 has a cylindrical hollow portion 6b
4 and a notch 6b opposed to the O-ring 6a4.
5 is provided. The female screw 6b2 is embedded and fixed below the bottom 6b. The female screw 6b2 has a hole 6b3 through which the fishing line 5 passes. [0011] A cylindrical cavity 6b4 at the upper portion of the bottom shown in FIG.
Is fitted with the top O-ring 6a4 in FIG. This fitting portion is tightly fitted with an O-ring 6a4 wound around the circumference of the top cylindrical portion 6a3 of the top 6a of the float 6 so as to prevent water from entering the inside of the float even in seawater. 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 rotated with both hands to thereby adjust the top 6a of the float 6. And the bottom 6b are separated from each other. As a result, the volume of the whole float increases and decreases, and buoyancy can be adjusted. It is important to increase the variable range of the buoyancy of the float in order to respond to the various fishing situations described above.
The moving distance of the space 6c is set to 1, and the O-ring 6a4 and the kerf 6
Assuming that the contact point of b5 is the radius r from the center of the float and the volume v of the whole float, the variable range (rate) of the buoyancy of the float is πr ² 1
/ V. Therefore, it is necessary to increase the variable range and provide the above-mentioned contact on the outer periphery as much as possible. Also, the top 6a and the bottom 6b of the float 6 are increased in order to increase the variable range of the buoyancy.
As shown in FIG. 7, in order to make the fitting portion as far as possible outside the circumference of the float, the cut groove 6 on the upper portion of the cup 6b1 on the bottom 6b
b5 is extended so as to overlap the head 6a1 of the float 6a, and furthermore, the gap 6 at the fitting portion in FIG.
By using c, the top 6a of the float 6 is overlapped with the bottom 6b as shown in FIG. 7 in order to reduce the resistance when the float moves in the water and the air resistance when the device is thrown in. When the buoyancy is moderated by rotationally fitting the top 6a and the bottom 6b of the float 6, the air inside the float is compressed or expanded because it is sealed by the O-ring 6a4. When the air rotates and compresses or expands the air inside the float, the torque required for the rotation increases, and an extra force is required. In order to avoid this, the inside of the float top of FIG.
It is also effective to provide the cavity 6a5 to lower the compression ratio as described above in order to facilitate the operation. According to the float for fishing fish of the present invention, the top 6a and the bottom 6b of the float 6 are grasped by the left hand and the right hand, respectively, and are rotated clockwise or counterclockwise, whereby the float 6a of the float 6 is formed. As a result, the volume of the entire float increases or decreases, and the buoyancy can be adjusted. In the float for fishing fish of the present invention, 1
Since it is possible to continuously adjust the buoyancy with the individual floats to search for fish shelves, fine adjustments can be easily made according to the situation, and an improvement in fishing results can be expected.
