Description

Description: [0001] [Industrial field of application] The present invention eliminates the need for a docking place or the like to block a beach, allows a small vehicle to be easily carried, and allows a small yacht to freely land and leave from a pristine waterfront. Structure and assembly ~
It is a comprehensive set of many devices that make maneuvering easy, and can be used for sports that do not waste fuel-clean the waterfront, or for fishing and water transportation.

[0002] [Prior Art] Conventional yachts, even small catamarans, can not be loaded on ordinary cars and must be carried by trailers or connected to the coast for many times to pay, and round flat bottom rubber boats are carried. Easy, but difficult to sail-cross winds make it unsuitable for sailing.

[0003] [Problems to be solved by the invention] In yacht manufacturing, it is difficult to satisfy the contradictory conditions of robustness and lightness, and therefore the price is high, and there are many ship types that are difficult to start from shallow water, and they are to be stored. Also, because it takes a place such as a mooring place and it also costs to transport,
Illegal mooring is also increasing, which is one of the causes of polluting the waterside nature.

[0004] The present invention can be folded into a minimum volume for easy storage and transportation, is quick and easy to assemble, has high sailing performance, and can be safely operated by beginners. Solved by various ideas described in detail, anyone can get a yacht at a low price, free from the waterfront of nature, not just a rich man, but use only natural wind power ~ waste fuel As a healthy sport, the purpose is to help spread.

[Means for Solving the Problem] As shown in the figure, the present invention is a panel-shaped deck (2) having two columnar floats, which are easy to manufacture, to which side plates (5) for preventing lateral flow are attached. Combined so that they are held, arranged vertically and passing the main girder (3) and rudder girder (4) at a right angle, you can easily assemble them with only the fittings and four bolts. As shown in FIG. 3, the nut can also be tightened sufficiently with bare hands by embedding it in a thumbscrew-type hardwood (14) to prevent it from being lost on a sandy beach and as a rope stopper. When carrying a light wagon, two masts are passed from the rear of the vehicle to the ground to serve as a stand, the deck (2) is lined up face down, and the hinged side plate (5) stands upright. Pass the fixed rod through the rear end and the side of the deck, connect it to the main girder (3) and the rudder girder (4), and attach it to the sheath type metal fitting that is attached to the position 1/3 from the front end of the side plate. If you insert the L-shaped metal fittings at both ends and fix it, and attach the float (1) with hook bands, raise the hull of about 25 kg and put it between both decks, it is easy to carry to the beach.

[0006] Connecting the mast and connecting the base to the center of the main girder,
Twist the wire (8) and the cord (2) each on the tip of the wire to the rear end and hang back the wire bottom tambuck (wire-
Stop the screw fittings that extend and retract the rope, attach the strut (10) to the tip of the deck, and pull the two tension ropes from the bow side to lightly set the mast (7) and attach it near one end of the tension rope. The hooks-on the front holes of the pillars (10) attached to the front end of the deck, and temporarily fix them, and one side goes through the holes and returns to the top, pulling it down through the ring attached to the rope Tightening ~ Knotted. There is also a method of attaching elastic fittings to the end of the tension rope, but it is lighter to use a ring.

[0007] The tilt of the mast is corrected by the wire tanb and the tension rope, and the lift (sail raising rope) is usually 2 masts.
It has a double length and is easily tangled if it is struck, but in the present invention, it loops between the pulley of the mast and the spring hook at the base and has rings at both ends, pulls it up with hooks at the top of the sail, and descends It can be fixed simply by hanging the ring on the spring hook.

[0008] The sail girder (12), which is intermediately connected, is attached to the bag-shaped part at the lower end of the sail, and the front rope (15) is attached to the tip of the sail girder. The front part of the sail can be put out arbitrarily in front of the mast, and the effect of jib sail can be obtained even with a single sail. Also, in the case of tail wind, since the conventional sail receives wind on only one side of the mast-the ship is deflected and becomes unstable in the forward lean, but the sail of the present invention can extend the front rope and make the center of the sail close to the mast, The hydrofoil near the bow increases buoyancy and prevents forward leaning-stable sailing.

[0009] Further, if two tow ropes (14) are attached to the rear end of the sail girder and they are passed through rings provided at both ends of the rudder girder and a wood stopper type stop tree (16) is inserted, any rope position can be easily set. Can be fixed to. With this idea and the idea of making the rudder all-type, in the case of the most difficult windward decimation running-it is necessary for the occupant to change the position (center of gravity) while operating the sail and rudder in the past. If the foot stops, there is a risk that the rudder will not work at all, but in the present invention, even if you do not touch the sail rope, if you lay the water surface of the stern sideways with the all-type rudder, you can arbitrarily change the direction of the ship, The wind pushes backwards Just by grasping the sail girder and moving the tip to the leeward side of the mast, the rope on the windward side is automatically stretched, and the sail will be at an appropriate angle regardless of whether the wind is received from the left or right ~ The ship is windward Can be traced back to.

[0010] Further, as the speed increases, the water pressure and buoyancy on the deeply sinking side of the hydrofoil increase-not only reducing the wave-making resistance, but also the effect of correcting and stabilizing the inclination of the ship.

[0011] Also, catamaran has excellent lateral stability, but if there is no wind, use two long and heavy oars-other than sitting on the bow and using a paddle-it is difficult to go straight with a wide hull.
The folding type web board (11) shown in FIG. 4 of the present invention is hung from the sail rope by a string whose part is made of rubber, and is lowered between both decks. If you push it forward, the plate will fall backwards-reducing resistance and sliding on the water surface, pulling it up at a right angle-the weight of water stretches the rubber and sinks the entire surface of the plate,
The water in front of the center of gravity of the ship can be swept backwards to go straight-all the power can be used for propulsion (not for swinging the oar). Also, due to the pulling action, the plate and the pull rod can be made of a very light material, which saves much more weight than loading oars or turrets.

[0012] In the prototype ship, length 180 cm and width 5 during transportation
The range of 0 cm height and 40 cm ± is easily accommodated in the lower part of the rear room of a light wagon, and the weight of the hull that is assembled and carried to the waterside is 25 on the left and right decks with floats, main girders, rudder girders, and hydrofoil.
A seat plate (18) that is kg ± and is durable and can be used as a float to pass it anywhere between the mast, rudder, sail, rope and deck.
Even if combined, the drainage is about 40 kg + the weight of the occupant, which is super lightweight, but since the two inflated floats of 2,4 m long have about 200 kg of buoyancy, it is possible for two ordinary people to hang a sail of 6 m ² or more. You can safely enjoy the sailing performance comparable to that of a riding yacht.

[0013] In addition, since the sail girder (12) of the present invention to be inserted into the bag-shaped portion at the lower end of the sail has no pulley or the like in the middle, the sail surface is lowered to lower the sail girder in strong wind. If it is wrapped around and tied with a string, the sail area can be easily reduced-the safety can be increased and the marine vessel maneuvering is easier than that of the conventional yacht.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The assembled yacht of the present invention can easily carry not only carriers of ordinary cars but also light wagons because of the feature that the volume during transportation can be minimized. It eliminates the need for docks and piers that disturb
It's also lightweight and small enough to make it affordable for everyone, not wasting fuel-sports that disseminate technology that harnesses the power of nature without damaging the planet, or water transportation or fishing that does not require fuel for larger ones. , A comprehensive set of innovations and technologies that can exert great effects on hydrogen production vessels using temperature difference power generation.

[0002]

2. Description of the Related Art Most of the main sails of a conventional type yacht are long sail girders that are nearly horizontal, and the lower end of the sail is sandwiched between the girders to form a flat surface. The hull form is associated with structural drawbacks. It is not the mere buoyancy of the sail surface that propels the sailboat, but the buoyancy of the wing of the aircraft,
A curved surface that is parallel to the course-a negative pressure that occurs on the convex side-a suction force), and a sail surface that does not generate propulsive force rather has the adverse effect of reducing performance. For example, if you embed the widest lower end of the main sail in the girder,
The shape of the longest trailing edge of the sail increases the up-down curvature, but this does not help propulsion-rather tilting the ship or sail to wind Reduce potency. Also, the operating point of the sail girder to operate and the center of the wind force acting on the sail are far apart in the conventional type-inevitably the sail is twisted, which also reduces the effective curved surface. Furthermore, in the case of tail wind, the sail with a wide lower end hits the support line of the mast and can not be stretched right beside, and in addition, wind force acts only on one side and the ship is deflected, if the rudder angle is increased to prevent it, The wave-making resistance increases sharply and slows down the ship. Especially since the horizontal sail girder is close to the deck, there is often an accident in which a sudden gust suddenly blows the head of the occupant and blows it off to the sea. Also, the conventional rudder will not work at all if the boat loses its speed-it is a zigzag traveling that is essential for the yacht to go upwind, and when repeating thinning and tacking, it is pushed by the wind from the bow side. Ships tend to fail,
If it stalls, it becomes impossible to operate the ship anymore, and the ship is overwhelmed by crosswinds – there are many cases of capsizing. That is, as long as the conventional sail and rudder are used, there is always a risk of an accident involving human life-the most important safety problem. In addition, in order to reduce the lateral flow and inclination of the ship-if a large center is pushed out to the bottom of the ship and weight such as a plast is added, the ship will inevitably become large-it will not be possible to sail without facilities such as a pier and the manufacturing cost Because yachts are expensive, it's easy to overlook that yachts are a rich hobby, and that is an example of a wonderful technology that harnesses the power of nature. I had to pay for it at the airport, and I hate it, and illegal mooring increased, hindering water transportation, and the number of people who scatter harmful exhaust on water scooters and motor boats sharply cut the fish nets. The number of accidents that injure people is increasing every year.

[0003]

[Problems to be Solved by the Invention] Under the current situation, pollution of nature-destroying destruction-Unless the reverse of "the trend that eats the irreplaceable earth and is not ashamed", the next generation will run out of fuel resources. Therefore, it is inevitable that we will be forced into destruction due to the increase of hazardous waste. Therefore, in order to reassess the benefits of the power of nature, we have reduced the weight and size of conventional yachts to overcome the hard-to-obtain drawbacks. Transportation volume reduction technology that eliminates the need for a dock. And, fundamentally, the technology to improve the sailing performance and safety by eliminating the drawbacks of the conventional sail type, rudder, and hull ~ The present invention is applied to a fuel-free transportation ship, a hydrogen-producing ship that is a harmless power source. There is an urgent need to promote the practical application of such applications.

[Means for Solving the Problems] The first of the means is the idea of reducing the weight and cost to reduce the cost and minimizing the volume during transportation to facilitate the transportation. (2) is filled with gas to give it elastic strength, and is attached by spring fishing and an L-shaped pipe so that the upper surface is surrounded by the side plate (S) which is the side of the deck (D) port on the panel with the lateral flow prevention side plate (S). -A mast (7) and a sail girder that are arranged in parallel and connected to each other by connecting the main girder (1) and the rudder girder (3) with bolts (4) that are also used as ropes to form a rectangular hull and divide the mast (7) into a length that is easy to carry. (9)
The length of the main sail (M) is covered by the mast, and in the simplified model, the front rope of the front sail (G) doubles as the front support line. Eliminates ropes for raising and lowering sails and pulleys that are prone to bite into the ropes.The lower end of the side plate supports the hull during assembly and protects the float from shallows during sailing, but the cylindrical float is divided into two chambers. -If it breaks, the loss of buoyancy will be one-fourth ~ Safety will be improved by preventing sinking, and if you fold by reducing the gas on one side before and after transportation, you can halve the filling during assembly. However, if you use an air injection pipe that can be connected to the exhaust pipe of the carrier, the filling time will be short. To give an example of how easy it is to carry ... The prototype yacht of the inventor is 180 cm long and 60 c wide and 60 c high.
It can be reduced to a volume of m ±, the weight of the hull is about 40 kg, the hull can be easily floated on water and returned to the shore, and thick bamboo can be used with a roller-with less force.

The second of the means eliminates the drawbacks of conventional sails,
It is a device to create a small sail with high propulsion efficiency, and the fact that the power to advance the ship is not proportional to the breadth of the sail is clear from the fact that the sailing speed greatly differs depending on whether there is a front sail narrower than the main sail The reason for this is that the front sail has a shorter trailing edge and therefore has less vertical curvature-it is easy to form a forward-facing effective curved surface to an airfoil because no girder is attached. Therefore, in the present invention, the mast is moved farther from the bow than in the conventional position, the front sail (G) is enlarged, the rear end of the sail girder (9) is raised, and the distance between the mast and the deck is widened to cause the worst accident. To prevent the possibility of being hit by the sail girder, cover the mast with the front edge of the main sail in the form of a bag, and connect the upper and lower ends to the middle of the upper rope and the upper and lower ends of the sail girder by connecting the upper and lower ends of the sail girder. A wing-like shape-By constructing a wing-type sail whose trailing edge is almost vertical, the center of the wind force on the sail and the point of action of the sailing power are brought close to each other-to minimize the vertical bending and twist of the main sail. In addition to the advantage of lighter sailing due to the principle of leverage, the synergistic effect that the wind acting on the curved surface of the front sail further accelerates the air flow on the curved surface of the main sail is also utilized-Propulsion force per area of sail It is an idea to bring it to the highest level.

The third means is to radically improve the conventional dry sail method in which the sail rope is tightened or loosened on the narrow ship and the foot is caught by the rope whenever the weather or wind direction changes suddenly. It is a simple idea, and attach two chords (F) to the rear end of the front sail (G) to surround the mast-through the spring hooks at the lower ends of the mast ropes on both sides, Near the rope where it can be stretched-Connect both ends with hooks to form a loop, and attach two dragnets (H) on the left and right to the rear end of the sail girder (9) and thread the rings on both ends of the rudder girder. By fixing the main sail to a proper length to the rope stop (4), loosen the front sail for repeated tack-to-track switching to windward zigzag-by turning the rudder to turn the ship , The sail automatically moves downwind-the main sail is at an appropriate angle without touching it, just pulling the sorting rope and sandwiching it in the rope stop- The most difficult and has been windward to proceed with the ship operation come it can be extremely simple. Also in the case of tail winds, the wing-type main sail with a high rear end is stretched at an angle close to the side, and a wide front sail is divided by a rope to the opposite side of the main sail. Because the wind force that works on the machine is balanced to prevent the deflection, the follow-up wind can be fully utilized without increasing the steering angle and wave-making resistance. In addition, the front lower end of the front sail is hooked on a small crank (C) that vertically penetrates the diagonal front end, and if the sorting rope is loosened and the crank is turned, it will be wound around the rope at the leading edge of the front sail in a rod shape-preventing rattling. If you fix the main sail right behind in this way, you can turn the bow toward the wind-easy stoppage on the water.

[0006] The fourth means is most likely to occur at the time of assembling on the waterside-it is a device to prevent the trouble of losing small parts and to eliminate the need for assembling tools. Conventionally, bolts are used to connect vehicles. Double-tighten the nut with a wrench or wrench so that it will not come off even if you shake it-Use a retaining pin to prevent it from falling off, but this is troublesome and hard to find if dropped at the water's side. In the present invention, the head of the bolt is formed into a P shape that is easy to hold with bare hands, and the nut is designed to be embedded in the vertical hole of the bamboo boat type rope stopper made of hardwood, so that it will not be hidden in the sand and will not sink in the water even if dropped. It can be fully tightened even with bare hands, and when it gets wet with water, the tree will still tighten and prevent loosening, and it will not be necessary to separately install a rope stop that is indispensable for ships, and it will not require tools that increase the weight. As for (4), as shown in the figure, the rope is cut into the bottom of the wooden mold to prevent it from returning, and it can be tied around the upper handle part, making it easy for beginners-
Since it can securely fix any part of the rope, it can be used for connecting equipment of various ships, not limited to yachts.

[0007] The fifth means is a comprehensive set of various ingenuity measures to minimize the time from arrival at the waterfront to the launch of sails. In principle, the number of parts used is minimal, no special tools are used, and the number of steps is as small as possible. ~ For the sake of simplicity, thick bolts with rubber bands are used to prevent the bolts that are also used for fastening the rope, the insertion metal fittings, the spring hooks, and the movable connection portion from falling off, and can be easily assembled even by a weak beginner. Standing mast-
For the extension of the main sail, the front sail's leading edge is made into a bag shape and the mast is covered so that the ropes and pulleys for raising and lowering are not required, and the mast-sail girder and the tip are connected, and the oblique girder is temporarily erected upward. Just like pulling to the bow side using a lever, the mast stands so that a large fan that opens the center of the main girder opens to open the front sail, the main sail, and supports the diagonal girder on the pipe Fasten the ropes to the left and right bows-Hang the seat plate (Z) between the decks-Install the rudder (R) to assemble and launch in a short time, and in addition to the features that do not require pier equipment, in an emergency such as lifesaving Is also useful. Further, with the prismatic float type yacht according to the above-invention 8, the assembling time can be further shortened.

The sixth means is to solve the major drawback of the conventional rudder, which tends to be incapable of maneuvering when repeatedly tacking or changing course during windward movement. With an L-shaped universal latch (L) that can be inserted sideways and a rudder plate (9) that combines a rudder plate that can arbitrarily change the angle with the rudder handle, a large rudder plate protruding to the stern was devised. If you pour water on the stern sideways, it will stall ~
Even a ship in a stopped state can be swiftly turned 180 degrees on the spot, so the risk of being incapable of maneuvering can be reduced to almost zero. Further, even when a ship which is apt to be deflected to the windward side when sailing in a crosswind is controlled by the rudder, the all-rudder (R) for turret of the present invention comes to the occupant whose balance is on the windward side. Easy to operate, if there is no wind, loosen the long bolt (N) of the rudder and change the angle of the rudder plate and the direction of the latch horizontal axis to easily change to a light turret and proceed with rowing. It is more convenient to put a ship in a narrower area than the oar, and unlike the oar that does not work one way, the oar rudder with turret of the present invention produces propulsive force in both reciprocating directions, so there is no loss of power and 45 ° ± The turret that cuts into water at an angle of ~ creates a propulsive force is closer to the blade of the screw in principle, and it is more efficient to rotate the large screw slowly than to rotate the small screw at high speed- Operation that does not allow it to be efficiently promoted by rowing Kill. If the turret cannot be used, move the free latch to the port side-install a spare oar on the opposite port,
Even beginners can easily row.

The seventh means is to devise the simplest sailing device. With the structure and device described in claim 7, a lifeboat indispensable for a large ship, a highly efficient winged sail and operation are provided. If equipped with an easy-to-use turret and all-rudder, it will have an excellent propulsion function and the lifesaving rate can be greatly increased. Also, the characteristic that it does not exhaust physical strength is also useful for leisure for elderly people who do not like earth pollution and noise. It is optimal and can also be applied to children's boats, so it will also help boys to acquire the technology that utilizes the power of nature most needed for the future earth.

The eighth means is to devise a hull which further enhances the sailing function and enhances the safety, and the prism of the prismatic float described in claim 8 having a narrow bottom and a vertically long cross section also has a mechanical strength. It's high, and if you use it for a catamaran, the buoyancy on the inclined side will increase sharply-
It has the effect of reducing the inclination of the ship and makes use of it-The prismatic float side-by-side assembly yacht has high sailing performance and, in the unlikely event that the floating chamber is damaged, the loss of buoyancy is 1/4. All you need to do is to seal the damaged area with a waterproof pad and underwater adhesive.-By pumping out the water from the floating chamber, the sailing function will be restored in a short time. In addition, a flexible structure that can be bent vertically when riding in the ocean,
The propulsive force due to the vertical arrangement of the wing-shaped sails can be widely used not only for assembled yachts but also for large ships. For example, the wing-shaped main sails are made of light metal and are arranged vertically to make the catamaran have a wide breadth. If solar panels are stretched and the obtained electric power is used for powering sails, propulsion, and rudder, it can contribute to all industries as a fuel-less transportation vessel, and it has excellent stability, wave resistance, and wind to generate wind. The characteristic that does not flow is that the long stretchable flow tube is lowered into the sea while traveling around the sea area called the "sea desert" where there is little rain near the equator, and the electrolysis of seawater by temperature difference generation with the water surface ~
It is ideal for "hydrogen production vessels" that produce hydrogen at low cost, and if this large fleet is permanently placed in the desert of the sea and hydrogen, which is a harmless power source, is supplied to the whole world at low cost, it will contribute to humankind. It will be highly evaluated as a country with a very high degree.
