欠点があった。In conventional folding floating bodies that do not have an interlocking mechanism,
The cross-sectional view shown in the figure consists of two central floating bodies 2 connected by a hinge 1, hinges 3 on both sides, and an outer floating body 4 connected by a sash. When dropped, the buoyancy FIIF is below the water surface 5.
2 is generated upward and gravity G1. Since G2 acts downward on the center of gravity of the hand sword, it is in an unstable state, and as shown in Figure 2, the outer floating body 4 has M
1= Fl e 1. M2-F2 e for central floating body 2
The moment of 2 acts, and finally a new equilibrium state is reached in the third state. In other words, we want the outer floating body 4 to open outward, but according to experiments, there is some resistance for the outer floating body 4 to fall outward, and the lower part of the central floating body 2 opens earlier, so the outer floating body 4 A moment that causes it to fall inward begins to act (t), and eventually it remains in a balanced state as shown in Figure 3 without opening. Therefore, in order to open the outer floating body 4 to the outside, a torsion spring acting in the opening direction is provided at the hinge 3, and the same as when dropping the outer floating body 4 into the water. Either release this lock and apply a force so that the center of gravity of the floating body 4 moves outward from the center of buoyancy before the inward moment becomes too large, or After reaching the state shown in Figure 3, it was necessary to lift the outer floating body 4 with the rope 6 and open it outward. In this case, if a torsion spring is provided, it is necessary to apply a torsion force to the spring to lock it when folding the outer floating body 4, and lifting it with the rope 6 requires extra work.

た。Next, FIGS. 4 to 6 show the state when a conventional floating body without an interlocking mechanism is folded. Figure 4 is a cross-sectional view of the unfolded state, and when the hinge 1 is hung with the rope 7 and lifted, the moment shown in Figure 5 (the moment due to gravity on the central floating body 2 is M3 = 03.
e3 acts and the central floating body 2 is folded, but the outer floating body 4
It hangs down 1], and when it is completely lifted above the water surface, it will look like the one shown in Figure 6. Therefore, in order to fold the outer floating body 4, it is necessary to suspend it using the rope 6 and lift it in the direction of the arrow, which has the drawback of requiring extra work.

を有している。When folded from the state shown in Figure 10, gJ1
Fig. 1 shows the state in the middle of folding, and Fig. 12 shows the state when folding is completed. When the hinge pin 1 is lifted up with the rope 7 in the state shown in Fig. 10, the lifting force and the moment due to the gravity of the floating body cause the center floating body 2 to be lifted up. The lower end of z begins to close, and as shown in FIG. 11, each part moves in the direction of the arrow, and the outer floating bodies 4, 4' are lifted up and finally folded into the state shown in FIG. 12. In FIG. 1I, 04·G4 is the resistance moment against folding, and G3·G3 is the folding moment. G
4 is the mass of the outer floating body, G3 is the total mass of the central floating body and the outer floating body (G3>04), and the dimensions are 6
Since 3>84, G3・G3>G4・G4, and folding due to gravity is possible. According to this embodiment, the center floating bodies can be rotated by 180 degrees without causing a dead center. This has the effect that the outer floating body can be rotated 180 degrees with respect to the central floating body.

る。According to the present invention, since the outer floating body can be rotated 180 degrees with respect to the central floating body in conjunction with the 180 degree opening/closing movement of the central floating body, the central floating body and the outer floating body are automatically deployed when dropping into water. , when lifted out of the water, the central floating body and outer floating body are automatically folded, and I! ! No extra work is required for opening and folding, which has the effect of saving manpower and time.
