Abstract

Provided is a center-of-gravity movement uki that can maintain a linear flight posture during flight and does not invert when landing.
A rebound material is housed in the first half of the ground, and a weight is limited to a movable weight. With this structure, the weight 2 compresses the repelling material 1 and moves to the tip side during flight, so that the center of gravity sufficiently moves to the tip side, so that a straight flight posture is maintained. Then, when the water hits, the rebound material 1 pushes the weight 2 back to the base side of the base to provide a center of gravity moving base that normally stands up.

Description

  The present invention relates to a center-of-gravity moving room having an inverted prevention function.

  The center-of-gravity movement uki has a weight that can move to the uki, and when it is thrown using a fishing rod, the weight that can be moved by centrifugal force moves to the tip of the uki and fly in a linear posture as shown in FIG. The purpose is to reduce air resistance and to fly further.

  Conventional center-of-gravity movement uki has no function of preventing inversion when landing (for example, Patent Document 1, Patent Document 2, Patent Document 3, Patent Document 4) or a fixed weight at the base of the center-of-gravity movement uki to prevent inversion (For example, Patent Document 5).

  Since the center of gravity moves to the tip side due to the weight that can be moved at the time of flight, those that do not have an inversion prevention function will fly in a straight posture as shown in FIG. Water enters from the front end side and is inverted as shown in FIG.

  In order to prevent inversion at the time of landing, a fixed weight for preventing inversion is attached to the base of the center of gravity moving base (FIG. 5 shows an example in which a fixed weight is attached to the base of the center of gravity moving base). Even if it moves to the side, the center of gravity does not move sufficiently to the tip side, so the function of taking a linear flight posture becomes weak. Accordingly, the present invention intends to solve the above-mentioned problems by devising a center-of-gravity movement that does not invert when landing without losing the function of taking a linear flight posture.

  A cylindrical storage chamber is provided in the interior, and one or more metal weights having a spherical shape or a rod shape smaller than the inner diameter of the storage chamber are stored, and a repellent material is further inserted on the tip side of the weight. It solves the problem by providing a center of gravity movement featured by a structure.

  Since the structure that does not have a fixed weight to prevent inversion at the base of the center of gravity movement uki, when the weight that can be moved by the centrifugal force moves to the tip side during flight, the center of gravity moves further to the tip side to fly linearly You can keep your posture. When the water reaches the ground, the weight that allows the repellent material to move is pushed back to the base side of the center of gravity movement to prevent upside down.

It is a longitudinal cross-sectional view which shows the structure of the gravity center moving room of this invention. It is a longitudinal cross-sectional view which shows a mode that the structure of this invention was accommodated in the inside of a streamlined type. It is a longitudinal cross-sectional view which shows the mode at the time of the flight of the gravity center movement uki without an inversion prevention function. It is a longitudinal cross-sectional view which shows the state which the center-of-gravity movement uki without the inversion prevention function landed. It is a longitudinal cross-sectional view which shows the example which attached the fixed weight to the base part of the gravity center moving base for inversion prevention.

An embodiment of this invention is shown in FIG.
The rebound material 1 is made of a light material such as a sponge or a coil spring. The movable weight 2 is smaller than the inner diameter of the storage chamber 7 and is made of a metal such as lead, copper, tin and the like in a spherical shape or a rod shape. The main body 3 is made of resin.

  A storage chamber 7 is provided in the interior of the main body 3, and a movable weight 2 is stored in the storage chamber 3, and a repulsion material 1 having a length at least half that of the storage chamber is provided on the tip side of the movable weight 2. It has an interpolated structure. Here, the storage chamber 7 is a cylindrical space for storing the repellent material 1 and the movable weight 2 inside the main body 3.

  When the centroid movement uki of the present invention is thrown using a fishing rod, the weight 2 that can be moved by centrifugal force moves to the distal end side of the storage chamber 7 while compressing the repulsion material 1, so that the centroid of the centroid movement uki moves to the distal end side. Move and keep a straight flying attitude.

  When the center-of-gravity moving ground reaches the ground and the centrifugal force disappears, the weight 2 to which the repulsive material 1 can move is pushed back to the base side of the storage chamber 7. When the movable weight 2 moves to the base side of the storage chamber 7, the main body 3 tilts with the base side facing down. The weight 2 that can be moved by this inclination moves to the end of the storage chamber 7 on the base side. With the movement of the movable weight 2, the center of gravity moves to the base side of the main body 3 and stands up normally without being inverted.

  The center-of-gravity movement uki of the present invention can be implemented even in a cylindrical form as shown in FIG. However, in order to improve the appearance, a configuration in which the cylindrical structure of the present invention is accommodated inside the streamlined uki as shown in FIG. 2 is also possible.

  When it is necessary to reduce the diameter of the storage chamber 7, it is possible to store a plurality of movable weights 2 smaller than the inner diameter.
