Description

The present invention relates to a float for preventing rollover that is attached to the periphery of a boat body and prevents the boat body from overturning and, in some cases, serves as an auxiliary buoyancy body for the boat body.

In order to prevent small boats used for fishing, etc., from becoming unbalanced and unstable due to the movement of the angler, to prevent the boat from overturning and being thrown into the sea and drowning, In order to use as a buoyancy body when a boat sinks, a side float device has been proposed in which a float body is attached to the left and right sides of the boat body (see Patent Document 1).

Utility Model Registration No. 3095776

However, in the side float device described in Patent Document 1, the float body is attached only on the left and right side of the boat body, for example, when the angler's load moves to the front side of the boat body, When moving to the rear side, the boat body may tilt forward or rear. This tendency is conspicuous in a split type boat in which the overall length of the boat body is shorter than the width of the boat body.

The present invention has been made in view of such circumstances, and is used by being attached to a boat body. Of course, the right and left sides of the boat body (hull) are overturned even if there is load movement on the front side or the rear side of the boat body. An object of the present invention is to provide a float for preventing rollover that is difficult.

The float for preventing rollover according to the first device in accordance with the object is a float for preventing rollover that is detachably attached to the boat body and prevents the boat body from being rolled over,
It consists of a sealed bag-like sheet that is U-shaped in plan view and is filled with gas inside, and is attached to the outside of the boat body, below the ship's edge, above the floodline, and along the both sides from the bow. In addition, at the stern, a float body that is arranged to extend further backward than both sides,

The float for preventing rollover according to the third device is the float for preventing rollover according to the first and second devices. The length of the float body extended from the stern is 1 of the diameter of the float body having a circular cross section. It is in the range of 4 times.

And the float for preventing rollover according to the fourth device is the float for preventing rollover according to the first to third devices, and the boat body has a front or rear divided structure.

The float roll prevention float according to the first to fourth devices has a U-shaped float body in plan view, and is formed of a sealed bag-like sheet filled with gas. However, if a load moves to the front side of the boat main body, the front side of the float main body is immersed in water to generate buoyancy and prevent rollover.
In addition, the float body is arranged at the stern so as to extend further rearward than the both sides, so when the load moves to the rear part of the boat body, the stern of the boat body tilts. Buoyancy is generated in the extended float body to prevent rollover.

In particular, in the float for preventing rollover according to the second device, the fixture is attached to the float body in the form of a shallow box, and has a band insertion hole on the opposite side plate whose upper part is bent inward. And a mounting band that is inserted through the band insertion hole of the mounting bracket, surrounds the body of the float body, and is provided with fixing lock means on both side ends.
