Description

[Detailed description of the invention] This invention is a fender that softens the impact force upon contact on high-speed ships, etc., and has a wave deflection function to prevent water spray and waves from hitting the inside of the ship from the side. Regarding equipment.

For water surface vehicles that travel at high speed on water, such as high-speed boats, naval vessels, small fishing boats, motor boats, high-speed catamarans, flying boat floats, and hovercraft, the height of the bow from the water surface to the deck is the bow. Although it is desirable to make the height as high as possible because it has a close relationship with the wave overburden phenomenon, there is naturally a limit to its height. Figure 1 is a side view of a high-speed boat 01 traveling at high speed.During high-speed travel, waves 02 caused by the hull rise along the side, so Figure 2 As shown, water droplets 02a end up on the deck. In the conventional high-speed boat 01, countermeasures were taken such as providing a chain 03 in this part as shown in Figure 3, or providing a wave return 04 at the same height as the chain as shown in Figure 4. This prevents water droplets 02a from rising onto the deck.

However, even if the high-speed boat 01 takes such measures, when sailing in waves, the wave surface will be
1, the moment the hull 01 descends the most, it will be in the state shown in Figures 5 and 6, and the effect of the chain 03 or wave return 04 will not be exerted, causing water splash 02a and Depending on the wave 02
will be driven into the ship and washed on the deck. On the other hand, FIGS. 7 and 8 show schematic cross-sectional views of the vicinity of the upper side of a conventional high-speed boat. In some conventional high-speed boats, a fender 05 is installed near the upper part of the outer shell surface. The cross section of the conventional fender 05 is semicircular as shown in FIG. 7 or square as shown in FIG. 8, and protrudes about 50 to 60 mm from the outer panel surface. Fender material 05 with such a cross section and dimensions
When the water splash 02a as shown in Figs. 5 and 6 collides with the water, the fender 05 has a shape and size suitable for the wave returning effect, although there is a slight wave returning effect as shown in Figs. 9 and 10. Therefore, in this case as well, the water spray 02a had to climb over the fender 05 and hit the inside of the ship or wash the deck, which not only made work on the deck difficult but also caused damage to the tower-mounted equipment. . If you try to avoid this, slow down,
The ship was forced to give way or abort its voyage.

The fender device with the wave return function of the present invention is designed to prevent the wave-covering phenomenon that occurs when conventional water-based vehicles navigate at high speed in waves, and damage accidents to tower-mounted equipment during wave navigation. In addition to the chain or wave reversing device installed on the water surface vehicle of Even in waves where conventional chain or wave reversing equipment would be submerged in the water and unable to exert their effect, the device of the present invention, which is installed at a higher position, exerts its wave reversing effect. There is no wave splash, damage accidents to tower-mounted equipment and wave overlapping phenomena can be avoided, and various problems such as deceleration, avoidance, or suspension of navigation of water surface vehicles can be prevented, and these effects are small in size. The purpose of the present invention is to provide a fender device having a wave return function that enables navigation in sea areas with high wave height or sea conditions where conventional water surface vehicles cannot operate.

For this reason, the fender device having a wave returning function of the present invention is a fender device provided on the outer side plate surface of the ship for the purpose of protecting the ship. A lower edge member that continuously rises outward in a concave shape and whose outer end is substantially horizontal or descends; and a lower edge member that rises approximately parallel to the side skin surface and whose upper end is located at the upper end of the gunwale skin. It is characterized by being comprised of an edge member that

Hereinafter, a fender device having a wave returning function as an embodiment of the present invention will be explained with reference to the drawings.
11 and 12 are diagrams showing the cross section and wave-back state, and show the 11th part of the fender 6 attached to the gunwale on the upper side of the hull 1.
In the case shown in the figure, the lower edge member 6a rises outward in a concave shape continuously from the side shell surface 5, and its outer end is almost horizontal, and the edge member 6b
is provided with a convex contact surface facing outward. This fender is made of metal, rubber, wood, etc., and is configured to have a height of about 140 to 200 mm (h) from the outer panel surface 5. Further, the upper end portion of the edge member 6b is approximately equal to the upper end portion of the side outer plate.

In FIG. 12, the lower edge member 6a is the side outer plate surface 5.
The edge member 6b continuously rises outward in a concave shape and its outer end descends, and the edge member 6b is provided with an outwardly convex contact surface.

Further, FIGS. 11 and 12 above show how water spray 2a rises when a high-speed boat equipped with a fender device having a wave-turning function according to the present invention is traveling at high speed in waves. In both figures, the conventional chain 3 or wave return 4 is submerged in water due to the relative movement between the waves 2 and the hull 1, and its effect is not exerted.
Therefore, the water splash 2a rises along the shipside, but since the shape of the lower edge member 6a of the fender 6 of the present invention is concave and faces outward from the hull so as to deflect the water flow outward, the water splash 2a rises along the side. 2a changes its direction toward the outside of the hull along this shape, separates from the edge member 6b of the protruding fender 6, and does not fly outward and rise onto the deck. Further, it goes without saying that the outer end of the fender device 6 is provided with an edge member 6b, which also has a fender function.

As described in detail above, according to the fender device having a wave returning function of the present invention, the fender device is provided on the side outer plate surface of the ship for protection of the ship. A lower edge member that rises outward in a concave shape continuously from the side outer plate surface and has an outer end that is substantially horizontal or descends; The simple structure consisting of an edge member located at the upper end of the outer shell completely prevents water from splashing onto the deck, which can occur during high-speed cruising. This has the advantage of preventing damage to tower-mounted equipment without slowing down or giving way. It also has the advantage of avoiding sailing cancellations due to sea conditions.
