Abstract

<P>PROBLEM TO BE SOLVED: To provide a float for fishing designed to vary its volume through stretching/contracting a buoyant part for adjusting buoyancy. <P>SOLUTION: This float for fishing has the following structure: A float body as a variable air chamber having an inner diameter longer than an engagement length adhesive with the same diameter as that of an upper float is joined with the cylindrical buoyant part with a pipe-like shaft as the core and the upper float constituted of a feather of arrow on the tip for stabilizing float flying. Further, in this float, the volume of the variable air chamber can be changed by changing the joint length, and the exposed volume of the upper float can also be changed by changing the distance between the upper float and the float body, and the buoyancy of this float can be adjusted by attaching a rubber packing onto the float body in order to close the variable air chamber, attaching a rubber stopper onto the tip of an upper shaft and blocking the air in the upper shaft communicating with the variable air chamber. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

TECHNICAL FIELD The present invention relates to a fishing uki that allows easy adjustment of buoyancy.

Most of the fishing oysters have a constant buoyancy, but some of them change the buoyancy by the weight, which is practically sufficient.

However, there is a drawback in that fine adjustment cannot be made with uki when the water surface undulates or swells.

When a wave suddenly comes out or swells at a fishing spot, this defect has a problem that a fish enters the water even though it is not a fish trust, and it can be eaten even if it does not enter.

As an improvement measure, there is a method of creating a variable capacity air chamber in the main body. FIG. 1 is an explanatory diagram showing this method mounting form, and a main body having one variable air chamber having a shaft 2 as a core and concentric parts 3, 7, 5 (three points are bonded with an adhesive). It is sectional drawing at the time of joining of the upper space part. 8 is a rubber gasket for preventing water leakage into the variable air chamber, and 9 is a rubber stopper for preventing air leakage and air venting.

The problem to be solved is that when the state of the water surface changes, visual confirmation cannot be made with a wave that becomes an obstacle.

The most important feature of the present invention is that it has a variable air chamber for allowing the upper base portion to be stably observed according to the state of the water surface.

The uki of the present invention has an advantage that it has a variable air chamber and is lightweight and has a long throwing property with an excellent flight distance.

The purpose of adjusting the buoyancy of Uki was realized without removing other parts.

FIG. 1 is a cross-sectional view of the present invention, wherein 1 is a main body, 3 is an upper wall, and the volume of the variable air chamber is changed by changing the fitting length between the upper wall and the main body.

FIG. 2 is an example in which the buoyancy is adjusted to be small in the embodiment of the present invention. By reducing the capacity of the variable air chamber from FIG. 1 and moving the upper uki portion toward the variable air chamber, the volume of the exposed portion of the upper uki was reduced, and the buoyancy of the uki was reduced by about 2%. The buoyancy of the air chamber and the upper chamber is 0.75 g per cc, and the buoyancy of the main body variable air chamber increases by about 1 g per 1 cc increase. When the volume of the air chamber is increased by 1 cc, the buoyancy of the upper uki is combined with the buoyancy of the upper uki, resulting in an increase of about 1.75 g. Conversely, if the volume of the variable air chamber is reduced by 1 cc, the buoyancy of the whole can be reduced by about 1.75 g.
To keep the air pressure (atmospheric pressure) of the variable air chamber constant, seal the variable air chamber with 8 rubber packing, remove the 9 rubber plug before adjusting the buoyancy, and return it after the adjustment. The movement of the main body and the upper wall can also be prevented by the air spring effect.

It is whole sectional drawing of Uki. It is explanatory drawing which showed the implementation method.
