Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sailing ship, and more particularly, a buoyancy adjustment device is disposed in a hull constituting the sailing ship to make the hull submersible; The present invention relates to a sailing ship configured to be able to sail even when the hull is in a submerged state by always maintaining a mast holding a sail at a predetermined height above the water surface.

[Background of the Invention] Conventionally, sailing ships, such as yachts, which sail on water without using power by attaching sails to masts erected on the hull and receiving wind from the sails, have been widely used for leisure purposes. It is widespread.

Yachts navigate on water, and are therefore not designed to visually see underwater when giving way. If it is possible to see the water or the bottom of the water while sailing, it will make the sailing of the yacht even more interesting.

However, conventionally, it has been virtually impossible to navigate underwater by yacht. That is, as mentioned above,
A mast is erected on the hull of the yacht, and a sail is attached to this mast. Therefore, if the hull is submerged with at least the crew compartment kept liquid-tight, the hull will be submerged. As a result, the mast, sails, etc. become submerged in water. For this reason, it becomes impossible to sail the yacht with the wind caught in the sail. Therefore, as mentioned above, in order to sail a yacht by submerging the hull, it is not necessary to provide the yacht with a drive source such as an internal combustion engine and to apply a propulsive force to the yacht under the driving action of the drive source. must not.

Therefore, since the internal combustion engine and the device for converting the driving force of the internal combustion engine into the propulsion force of the yacht are provided in the hull, the structure of the yacht becomes extremely complicated, and the yacht itself becomes large. As a result, the operation of the yacht becomes complicated, and even less interesting.

[Objective of the Invention 1 The present invention has been made to overcome the above-mentioned disadvantages, and includes a ship body, a float having the function of a centerboard to prevent the ship body from flowing sideways, etc., and a mast for hanging a sail. In a sailing ship, a buoyancy adjustment device is provided to float and submerge the hull, and the float is slidably engaged with the hull and a mast is attached to the float, so that the hull can float and submerge. By configuring the float, mast, and sail to remain at a predetermined height position at all times and prevent the mast and sail from being submerged in water even in a submerged state, it is possible to sail on and under water. The purpose is to provide sailing ships with

[Means for Achieving the Object] In order to achieve the above-mentioned object, the present invention includes a buoyancy adjustment device disposed inside the hull for submerging and surfacing the hull, and a buoyancy adjustment device arranged in the vertical direction with respect to the hull. It consists of a float that is movably arranged and whose end enters the water, a mast that is attached to the float, and a sail that is stretched on this mast, and the hull is adjusted under the action of the buoyancy adjustment device.

In this case, the floating body 24 is formed of a flexible member, and air can be introduced into the floating body 24 from a compressed air cylinder to be described later. Further, a tube body 26 is connected to the floating body 24, and the tube body 26 penetrates the shielding plate 19a and connects to the passenger compartment 19.
The first buoyancy adjustment valve 28 is connected to the first buoyancy adjustment valve 28 disposed within the buoyancy control valve 28 . Therefore, it is easily understood that the air within the floating body 24 is led out to the passenger compartment 16 via the pipe body 26 when the first buoyancy adjustment valve 28 is opened. A hole 29 is formed in the upper surface of the hull 12 defining the first chamber 18, and water is introduced into the first chamber 1B through the hole 29, and the water inside the first chamber 18 is Configured to drain water.

On the other hand, in the second chamber 21, a fixed ballast 30 is fixed and a floating body 32 is disposed in substantially the same manner as in the first chamber 18. A compressed air cylinder 3 is connected to the floating body 32 via a pipe body 34.
6 connects. In this case, the compressed air cylinder 36 is
As described above, air is supplied to the floating body 32 disposed within the first chamber 18 through the pipe body 38 indicated by the broken line in the figure.

Further, one end side of a tube body 40 indicated by a broken line in the figure is connected to the floating body 32, and the other end side of the tube body 40 extends toward the passenger compartment 16 side, and the end portion is connected to a shielding plate. 19b and connects to the second buoyancy adjusting pulp 42. Therefore, the air within the floating body 32 is led out to the passenger compartment 16 via the tube body 40 under the rotation of the second buoyancy adjustment valve 42. In addition, the hull 12 that defines the second chamber 21
A hole 44 is formed in the upper surface of the second
It serves to introduce this into the chamber 21 and to drain water from it.

Next, the float 1 is placed on the passenger compartment 16 side of the second compartment 21.
4. That is, the float 14 is connected to the second chamber 2.
The hull 1 through a plurality of rollers 46 disposed within the hull 1
2, in the figure, the float 14 is engaged so as to be freely displaceable in the vertical direction, and the float 14 has a substantially streamlined cross section in order to avoid the influence of water pressure as much as possible when the sailboat 10 sails. . Furthermore, a ballast 4 is provided at the lower end of the float 14.
8 is arranged to adjust the buoyancy of the float 14.

The float 14 has a hollow and long mast 5.
One end of the mast 50 is fitted and fixed, and the other end of the mast 50 protrudes upward from the upper end of the float 14 and terminates therein. A pipe body 52 is connected to an intermediate portion of the mast 50, which communicates the inside of the mast 50 with the passenger compartment 16.

Furthermore, the mast 50 is provided at an intermediate portion of the mast 50.
A boom 54 extending in a direction substantially perpendicular to the mast 5
It is attached so that it can swing freely relative to 0.

In this case, a sail 56 is stretched between the mast 50 and the boom 54, and a wire 58 shown by a chain double-dashed line in the figure is attached near the tip of the boom 54.
8 is connected via a plurality of pulleys 60 to a winch 62 disposed within the passenger compartment 16. Therefore, the boom 54 can swing in a predetermined direction about the mast 50 under the driving action of the winch 62, and can direct the sail 56 in a direction where it can be affected by the wind.

In addition, in the figure, reference numeral 64 indicates a rudder, and the rudder 64 is configured to be operable within the crew cabin 16 via a wire or the like (not shown), and by operating the rudder 64, the sailing vessel 10 can be controlled. The direction can be changed.

The sailing ship according to the present invention is basically constructed as described above, and its functions and effects will be explained next.

First, as shown in FIG. 2a, it is assumed that the sailing ship 10 is sailing in the direction of the arrow with the hull 12 constituting the sailing ship 10 floating on the water. In this case, the floating body 2 disposed in the first chamber 18 and the second chamber 21 constituting the hull 12
At 4.32, a predetermined amount of air is introduced from the compressed air cylinder 36 through the pipe 38, 34, and the pipe is airtightly closed.

Therefore, the effect of submerging the hull 12 of the sailboat 10 will be explained. That is, the first buoyancy adjustment valve 28 provided in the passenger compartment 16 is opened to lead out the air sealed in the floating body 24 to the passenger compartment 16 side through the tube body 26. In this case, the air led into the crew compartment 16 and the carbon dioxide etc. that are emitted when the crew members breathe are discharged from the tube body 52 to the outside via the mast 50, and the interior of the crew compartment 16 becomes atmospheric. It is maintained in approximately the same state. When the air inside the floating body 24 is discharged, the floating body 24 contracts and the buoyancy on the first chamber 18 side of the hull 12 decreases, and as a result, the first chamber 18 side becomes below the water surface under the action of the fixed ballast 20. dive. Therefore, water flows into the first chamber 18 from the hole 29, and the first chamber 18 side is further submerged.

Next, the second buoyancy adjusting pulp 42 is opened to open the second chamber 21.
The air in the floating body 32 disposed inside is led out to the passenger compartment 16 side. As a result, the buoyancy of the second chamber 21 side decreases in the same way as the first chamber side, and the second chamber 21 side starts to dive under the action of the fixed ballast (30), and the second chamber 21 side starts to dive from the hole 44. 2
Water is introduced into the chamber.

Due to the above action, the hull 12 constituting the sailboat 10 dives below the water surface. In this case, the float 14 is
2 through rollers 46, substantially only the hull 12 is displaced downward in the figure along the float 14, and the float 14 It will maintain approximately the same state as when it is in the floating state (see Figure 2). Therefore, the sail 56 stretched above the float 14 via the mast 50 and boom 54 will not be submerged in water. That is, the sail 56 receives wind, allowing the sailboat 10 to sail in the direction of the arrow even when the hull 12 is submerged. The hull 12 can be submerged to a desired position by adjusting the amount of air within the floating body 24.32 under the action of the respective buoyancy adjustment valves 28.42 and the compressed air cylinder 36.

Then, in order to float the hull 12 again, compressed air is supplied to the floating body 24 from the compressed air cylinder 36 via the tubes 38 and 34, respectively.
．． It is sufficient to supply air to 32. That is, the floating body 2
The floating body 24.32 expands due to the air supplied to the vessel 4.32, and the water that has entered the first chamber 18 and the second chamber 21 is discharged to the outside, and the expanded floating body 24.32 expands the hull 12. The buoyant force increases and the hull 12 rises to the surface.

[Effects of the Invention] As described above, according to the present invention, a floating body for adjusting buoyancy is provided in the hull of a sailing boat that sails in the wind, and the crew compartment of the hull is kept liquid-tight. Moreover, a float having the function of a center board to prevent the hull from flowing sideways is provided at approximately the center of the hull, and is movable vertically with respect to the hull, and a mast for tensioning the sail is attached to this float. are doing. For this reason, by introducing air into a floating body disposed on the hull and drawing out the air, only the hull floats and submerges, while the mast and sail attached to the float may be submerged in water. There is no. Therefore, the sailboat can be sailed only by wind power without equipping the hull with a drive source and a device for converting the driving force of the drive source into propulsive force. As a result, there is an advantage that the sailboat can easily sail on and under water without complicating the structure or increasing the size of the sailboat. Furthermore, if the sailboat is sailed with the hull submerged, it is possible to sail the sailboat in a fairly stable state during bad weather such as strong winds.

Although the present invention has been described above with reference to preferred embodiments, the present invention is not limited to these embodiments.
For example, in place of the compressed air cylinder that supplies air to the floating body, a pump that supplies air from the crew compartment to the fluid may be installed. Various improvements and design changes may be made without departing from the gist of the present invention. Of course, this is possible.
