Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to a Tobashi float.

(b) Conventional technology In float fishing, which is traditionally carried out by floating a baited fishhook on the surface of the water, the tobashi float used to drive the fishhook into the target point has a large weight to drive it in, and a float that floats on the water surface. Because it requires a buoyancy of
A fairly large spherical or approximately egg-shaped one is used, and in order to prevent the thread from floating on the water surface and meandering, a sinking line whose specific gravity is greater than that of the water is installed. ing. (See Figure 6) (c) Problems to be solved by the invention Therefore, as shown in Figure 6, the line b between the tip of the fishing rod and the tobashi float a is approximately catenary-shaped. In particular, the vicinity of the float A is below the water surface C, and when the angler senses a fish and makes a matching motion, the line B is pulled in along the curved line due to water resistance. Float A is also pulled by line B and dives underwater, so the water resistance acting on Float A increases, delaying the timing of alignment, making it difficult to see when the fish is hooked, and requiring extensive alignment. There were drawbacks such as the winding of the line was heavy.

(d) Means for Solving the Problems In the present invention, the float body is formed into a substantially oval shape, and a pore is bored on the center line in the longitudinal direction of the float body for passing the thread through. Inside the float body, a weight is buried in the approximately lowest position with the pores in a horizontal state, and curved wing surfaces are placed on the left and right sides of the float body, which are located on the fishing rod side. curved concave surfaces protrude forward on the left and right sides of the wing, and the wing surfaces maintain a fixed angle of attack and an upper end angle with respect to the pores. The purpose is to provide Tobashi floats.

(E) Functions and Effects According to the present invention, the following functions and effects occur.

That is, in the present invention, by forming the float main body into a substantially oval shape, it is possible to reduce the resistance that the float main body receives from water when winding the line.

When the hole for thread insertion, which is drilled on the longitudinal center line of the float body, is in a horizontal state,
Since the weight is embedded in the internal part of the float body, which is approximately at the lowest position, it is possible to stabilize the attitude of the wing surface, which serves as a dynamic pressure receiving surface that protrudes from the left and right sides of the float body located on the fishing rod side. Thus, the float body can be effectively floated on the water surface.

In addition, the wing surface has a curved concave surface protruding forward from the float body, and has a fixed angle of attack and upper end angle with respect to the pore bored on the longitudinal center line of the float body. Since the attachment angle is maintained, when the line is pulled toward the fishing rod, the curved concave surface reliably receives wind pressure, thereby generating upward dynamic lift on the wing surface.

Therefore, when the line is pulled in the direction of the fishing rod, the three effects mentioned above act synergistically, allowing the Tobashi float to slide on the water surface while maintaining its horizontal position without diving into the water. This allows the winding of the thread to be made very light.

Therefore, the timing of the alignment can be made appropriate, and it is possible to easily determine when the fish is hooked, and furthermore, there is no need for large alignments.

(F) Example The example of the present invention will be explained in detail based on the drawings.
A shows the Tobashi float of the present invention, in which a pore 2 is bored in the center line of the approximately egg-shaped float body 1 and a guide line B is inserted through it, and when the pore 2 is in a horizontal state, A weight 3 is placed at the lowest position inside the float body 1.
is buried so that the float main body 1 maintains a constant attitude when it floats on the water surface, and a wing surface 6 serving as a dynamic pressure receiving surface 5 is provided on the fishing rod 4 side of the main body 1. protruding from the left and right sides of the

The cross-sectional shape of the wing surface 6 as the dynamic pressure receiving surface 5 forms a high-lift airfoil shape in which the lower surface 7 is curved upward and a curved concave surface 6a is formed in the center. It has a small approximately oval shape.

The wing surfaces 6 are provided on the left and right sides of the float main body 1 with curved concave surfaces 6a facing forward, and the wing surfaces 6 are approximately 45 degrees with respect to the center line through which the thread B is inserted.
It is attached to the float body 1 while maintaining an attachment angle consisting of an angle of attack α of approximately 5° and an upper end angle β of approximately 5°. 6
b indicates a curved convex surface.

The material of the float body 1 and the wing surface 6 is hard urethane foam, and the float body 1 and the wing surface 6 are integrally formed using a female mold.
is embedded inside the float body 1 by casting at the same time as this molding.

The Tobashi float A configured as described above is attached to the fishing line B, and when the fishing rod 4 is transferred, it acts as a weight to create the baited fishhook 8 and the hit float 9.
After being thrown into the target point, the line B sinks into the water and becomes curved in the shape of a catenary as shown in Figure 5, while it acts as a float and holds the fish. forming a line.

Then, the fishing rod 4 is aligned with the fishing line and the line B is rapidly pulled in the direction of the fishing rod 4, but the Tobashi float A comes into contact with the swivel 10 attached to the tip of the line B and is pulled out of the way. Fishing rod 4 with thread B
be drawn in a direction.

At this time, the Tobashi float A can reduce water resistance when winding the line by forming the float main body 1 into a substantially oval shape.

A weight 3 is buried in the interior of the float body 1, which is at the lowest position when the thread insertion hole 2, which is bored on the center line in the longitudinal direction of the float body 1, is in a horizontal state. Therefore, the posture of the wing surfaces 6 as dynamic pressure receiving surfaces 5 protruding from the left and right sides of the float body 1 located on the fishing rod side can be stabilized, and the float body 1 can be effectively floated on the water surface. can.

In addition, since the blade surface 6 is attached to the small hole 2 formed on the longitudinal center line of the float body 1 while maintaining a fixed angle of attack consisting of a constant angle of attack α and an upper end angle β, When the line B is pulled toward the fishing rod 4, wind pressure is applied to the curved surface 6a of the wing surface 6, and upward dynamic lift can be easily generated on the wing surface 6.

Therefore, when the line B is pulled in the direction of the fishing rod 4,
The three effects described above work synergistically to allow the Tobashi float A to glide while maintaining its horizontal position on the water surface without having to dive underwater, making it possible to take up the line B very easily. It can be made lighter.

Therefore, the timing of the alignment can be made appropriate, and furthermore, it is possible to easily see when a fish is hooked, and furthermore, there is no need for a large alignment.
