The present invention relates to a water leisure boat that does not include a prime mover such as a chain or a motor. It relates to a water leisure boat which can move on the surface by the driving force generated by moving the center of the water leisure boat up and down by moving the center back and forth or up and down (as a manpower).

Recently, as the leisure population grows, more people enjoy water sports in the water such as rivers, lakes or the sea, and accordingly, the sports used in the water are diversifying.

Typically, sporting goods used in water (or ocean) include yachts, bicycles (chain driven) powered boats, motor powered jet boats, water skiing, and the like. The power of sporting goods used comes from prime movers such as wind power and motors mounted on the sporting goods body.

Therefore, such conventional sporting goods are not only inconvenient to transport and carry to the shore, but also when the user moves the sporting goods used in the water in a desired direction, in order to move the sporting goods, a large fuel cost for a power source must be paid. Economic difficulties have arisen. Moreover, in the case of sporting goods that rely on wind power, it is restricted to enjoy sports by wind speed and wind direction.

The present inventors have grasped the drawbacks of the conventional sporting goods and researched to improve them.

The present invention provides a water leisure boat that is easy to carry and simple to assemble, and can be enjoyed safely by anyone on the water, especially at sea, and does not require wind power or a separate prime mover in a state in which it can float on the surface by its buoyancy. It is an object of the present invention to provide a water leisure boat which can be driven and driven by the user's manpower (depending on the skill level).

The water leisure boat that can move on the surface by generating a propulsion force by moving the center of gravity of the user according to the present invention by moving up and down the pin includes a first buoyancy member and a pair of left and right bow parts coupled by the first connecting shaft ; A wing portion that is detachably coupled to each of the bow portion and the connecting shaft and facilitates the change of direction; A frame detachably coupled to the bow portion by a second connecting shaft; A pin capable of engaging with the frame and exerting a thrust force; A third connecting shaft coupled to the frame and to which the foot rest can be additionally attached; And a handle detachably coupled to the bow portion.

The water leisure boat according to the present invention may further include a vertical tail wing including a second buoyancy member and coupled to the frame.

As the buoyancy member mounted on the bow of the water leisure boat, a solid material made of a material such as compressed styrofoam (foamed polystyrene) or an air tube filled with compressed air or helium gas may be used as the buoyancy member. In addition, the bow portion is made of a solid of the material so that the body can be used as a buoyancy member without using a separate buoyancy member. Components constituting the water leisure boat, such as the bow portion, the frame, the pin, or the vertical tail wing, may be separated and assembled, or alternatively, may be formed as a single body. In addition, the water leisure boat can be used for two persons by supporting the feet of each person on the left and right of the foot rest relative to the longitudinal direction of the boat. Furthermore, the handle and / or foot rest may be additionally attached to the water leisure boat in the longitudinal direction of the water leisure boat to produce a water leisure boat for two or more persons.

The material of the bow portion and the frame is FRP, epoxy resin, rubber, stainless steel or polyester resin, the material of the pin is preferably PE, nylon, silicone, or CFRP. The buoyancy member is preferably composed of a tube filled with compressed air or helium gas, or a solid of compressed styrofoam (foamed polystyrene) having a predetermined shape. These materials may be materials other than those mentioned above as long as the requirements of predetermined strength, corrosion resistance, workability, buoyancy, etc. required for water leisure boats are satisfied.

In addition, the water leisure boat 1 according to the present invention is easy to assemble and disassemble so that it can be mounted in the trunk of a passenger car, the main components of the bow portion (10, 10), the frame 20, the vertical tail wing (30) , And pin 40. The bow parts 10 and 10 can be separated from both sides symmetrically with respect to the longitudinal direction of the water leisure boat, and can be mounted on a general passenger car when disassembled. On the contrary, at the time of assembling the bow portion, protrusions and grooves are formed on surfaces where the left and right bow portions 10 and 10 contact each other to facilitate assembly. Assembly (combination) of the water leisure boat can be made easily with a hook and bolt. The change of direction of the water leisure boat 1 is made by the user of the boat using the handle 11 attached to the bow 10, which is the rotation of the water boat when the water leisure boat is rotated. The bottom surface of the wing in the direction and the surface in contact with the water increases to generate a large frictional resistance, on the other hand, the wing portion in the direction of rotation outward relative to the water surface is reduced in contact with the water surface reduces the frictional resistance, so the speed is relatively Faster than the wing portion in the rotational direction, the wing portions 15, 15 located on the left and right side helps to change the direction of the water leisure boat (1).

The materials constituting the bow and the like are fiber reinforced plastic (FRP), epoxy resin, polyester resin, compressed strofoam (foamed polystyrene) or carbon fiber reinforced composite (CFRP), etc. It is easy.

(Example)

An example of the use of a single water leisure boat 1 according to the invention is shown in FIG. 1.

The user of the water leisure boat (1) is because most of the buoyancy of the boat is concentrated in the bow portion (10, 10) and moving the center of gravity of the user in the vertical direction of the boat or the front and rear direction of the boat according to the vertical movement As a result, the pin 40 of the boat moves up and down so that the boat 1 can move forward. The boat 1 can be divided into a beginner, intermediate, and advanced type according to the width of the bow portion, which can be selected according to the user's skill. The classification of the boat as described above is based on the width of the bow portion, the width of the bow portion is narrow to the beginner, intermediate, high-end type. In addition, the high-end type, unlike the entry-level and intermediate type, can be provided with no vertical tail wing. Since the width of the bow of the beginner or intermediate type is wider than that of the high-end type, the friction area with the sea surface increases, so the propulsion force is required during the movement, but the safety of the boat is high. ) And wings 15 and 15, and the direction can be changed by utilizing the wings, so that the stability of the boat is somewhat lower but can be moved more quickly.

The waterborne that the user boarded by the first buoyancy member 18 (see FIG. 6) included in the bow portions 10 and 10 and the second buoyancy member 31 (see FIG. 6) included in the vertical tail wing portion 30. Leisure boat (1) can be stably floated at sea level is helpful in the case of sea fishing.

The buoyancy member is an inflatable that expands by injecting air, helium gas or hydrogen gas into the buoyancy member, or compressed styrofoam (foamed polystyrene), polyethylene foam (Ethyoene Vinyl Acetate), fiber reinforced plastic (FRP), or a material such as PVC can be made into a solid (solid) shape with a certain shape. Therefore, the buoyancy member having a certain shape and made in a certain shape can be used in combination with the frame 20 by itself being used in the bow portion.

In Fig. 2, the handle 11, which is designed in a double structure, is manufactured by bending a pipe such as stainless steel and inserted into and fixed to the bows 10 and 10 in a detachable manner. In addition, the handle 11 can be used as the support 12 to lean forward the upper body of the user when the water leisure boat is stopped, so that the user can reduce physical consumption and take a rest. When the boat is moved, the user can use the handle 11 as a handle to generate propulsion force and change the direction of the boat. The bows 10 and 10, the first buoyancy member 18, and the left and right wing parts 15 and 15 are formed concentrically with a hole through which the first connecting shaft 13 can be inserted. The first connecting shaft 13 with threads formed at both ends is inserted from one wing 15 to the other wing 15 through the bows 10 and 10 and the first buoyancy member 18. An insertion through is connected to each of the bow portions 10, 10, the first buoyancy member 18, and the left and right wing portions 15, 15. After being connected to each end of the connecting shaft by a threaded stopper 14 formed therein, the nut is coupled to each of the bolts by coupling the bow parts 10 and 10 and both wing parts 15 and 15 to be integrally assembled.
