MODES OF THE INVENTION

(12) Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

(13) FIGS. 1 to 5 are a perspective view, a bottom perspective view, a plan view, an exploded perspective view, and an exploded side view of a leisure boat 100 according to an embodiment of the present invention, respectively.

(14) As illustrated in the drawings, the leisure boat 100 according to the embodiment of the present invention includes a cylindrical boat body 110 where persons are on board, three connecting rods 131, 132, and 133 of which one end is coupled to the body 110 and which protrude outward, and three floating bodies 121, 122, and 123 which are coupled to the other end of each of the connecting rods 131, 132, and 133, respectively.

(15) A seat 140 is installed on the inner wall of the boat body 110 in the boat body 110, a table 160 is installed at the center of the boat body 110, and a sunshade screen 170 is installed on the top of the boat body 110.

(16) The leisure boat 100 according to the embodiment of the present invention has an advantage in that since a load of the boat body 110 where persons are on board is distributed to three floating bodies 121, 122, and 123, the leisure boat 100 has still higher safety than the conventional leisure boat which relies only on buoyancy of the boat body 110.

(17) In particular, since each of the floating bodies 121, 122, and 123 shows the buoyancy at a position spaced apart from the boat body 110 by the length of each of the connecting rods 131, 132, and 133, it is advantageous in that the boat body 110 does not easily rock. That is, since the boat body 110 is positioned at the center of each of the floating bodies 121, 122, and 123, the boat body 110 is not significantly shaken even though the passengers stand up or move, and as a result, there is no possibility that the passengers will carelessly fall into water or the boat body 110 will be turned over.

(18) In the embodiment of the present invention, three floating bodies 121, 122, and 123 are placed centering on the boat body 110 at an interval of approximately 120. However, since the number of floating bodies is not particularly limited to three, four or more floating bodies may be placed centering on the boat body 110 at the same angle.

(19) The boat body 110 of the leisure boat 100 according to the embodiment of the present invention is formed by assembling a lower body 112 and an upper body 114 to be removable.

(20) When the lower body 112 and the upper body 114 are separately manufactured, the shape of each mold used for manufacturing the lower body 112 and the upper body 114 is simplified, thereby significantly decrease manufacturing cost.

(21) Each of the lower body 112 and the upper body 114 is preferably made of a thermoplastic resin material such as Acrylonitrile Butadiene Styrene (ABS), Polypropylene (PP), Polyethylene (PE), or Polycarbonate (PC). When such a material is used, water pollution may be reduced as compared with the convention FRP made hard boat and the manufacturing cost and a process time may be reduced by a method such as vacuum molding.

(22) The lower body 112 serves to generate the buoyancy and provide a boarding space as a cylindrical shape including the bottom and the side wall. In particular, a seating portion 112a protrudes on the top of the side wall of the lower body 112 laterally. The seating portion 112a is preferably formed in a horizontal direction, but may have a slight inclination. An upper periphery 112b protrudes upward on the end of the seating portion 112a as illustrated in FIG. 6.

(23) Meanwhile, when the lower body 112 is made of a transparent material, a user may observe the inside of water to double fun.

(24) The upper body 114 is a part that forms the side wall of the boat body 110 together with the side wall of the lower body 112 and has a plane shape like a ring. The bottom of the upper body 114 is held on the edge of the seating portion 112a of the lower body 112 in assembly and in particular, a bottom periphery 114b which protrudes downward from a lower edge of the upper body 114 is coupled while covering an exterior of the upper periphery 112b of the lower body 112.

(25) The seat 140 includes a ring-shaped seat plate 144 and a supporter 142 that extends downward from an inner edge of the seat plate 144 as illustrated in FIGS. 4 and 5.

(26) The seat plate 144 is a part which is held on the seating portion 112a of the lower body 112 and on which the passenger straddles a hip. The supporter 142 preferably has a height as high as the bottom touches the bottom of the lower body 112, but the seat plate 144 is held and fixed on the seating portion 112a, and as a result, the seat plate 144 may be spaced apart from the bottom.

(27) In the embodiment of the present invention, a circular coupler 150 is used as a means for coupling each of the connecting rods 131, 132, and 133 to the boat body 110. The circular coupler 150 includes three coupling tubes 154 into which the respective connecting rods 131, 132, and 133 are inserted and a circular connector 152 connecting the respective coupling tubes 154 to each other as illustrated in FIG. 4 and has a ring shape corresponding to the seating portion 112b in overall.

(28) The circular coupler 150 is held on the seating portion 112a of the lower body 112 and the seat plate 144 of the seat 140 is laid on the top of the circular coupler 150.

(29) That is, as illustrated in the exploded cross-sectional view of FIG. 7a and the assembly cross-sectional view of FIG. 7b, the circular coupler 150 and the seat plate 144 are sequentially laid on the seating portion 112a of the lower body 112 and the lower body 112 and the upper body 114 are coupled to each other while the upper body 114 is laid thereon.

(30) In this case, since an inlet of the coupling tube 154 of the circular coupler 150 is exposed to the outside of the boat body 110, grooves 117 and 118 need to be formed so that the inlet of the coupling tube 154 is exposed to the upper periphery 112b of the lower body 112 corresponding to the coupling tube 154 and the lower periphery 114b of the upper body 114. Through-holes may be formed instead of the grooves 117 and 118.

(31) A step portion 114a which is higher than the bottom of the lower periphery 114b is formed inside the lower periphery 114b of the upper body 114. The step portion 114a presses an outer periphery of the seat plate 144 from the top to serve to fix the seat 140 and the circular coupler 150.

(32) In such a placement state, when the lower periphery 114b of the upper body 114 and the upper periphery 112b of the lower body 112 are coupled to each other by a bolt, and the like, the positions of the seat 140 and the circular coupler 150 are fixed without using the bolt, and the like.

(33) FIG. 7c is a diagram illustrating an assembly cross-section of a part where there is no coupling tube 154 in the circular coupler 150. In FIG. 7c, it is illustrated as if the circular connector 152 floats in the air without a separate supporting means, but three coupling tubes 154 support the seat plate 144 of the seat 140 at different locations. A separate supporting means may be additionally installed between the seating portion 112a of the lower body 112 and the seat plate 144 of the seat 140.

(34) Meanwhile, each of the connecting rods 131, 132, and 133 is inserted and fixed into each coupling tube 154 of the circular coupler 150.

(35) In this case, as illustrated FIG. 8a, an elastic protrusion 137 having elasticity is installed on one end of the connecting rod 131 and when a fastening hole 156 is formed in the coupling tube 154, the connecting rod 131 may be more conveniently coupled. This is because when the elastic protrusion 137 is inserted into the fastening hole 156, the elastic protrusion 137 is not easily removed.

(36) Further, in order to more easily insert the elastic protrusion 137 into the fastening hole 156, a stopper 158 is formed on the end of the coupling pipe 154 as illustrated in FIG. 8b. That is, while the connecting rod 131 is pushed into the coupling tube 154 until the connecting rod 131 is caught in the stopper 158, when the elastic protrusion 137 is inserted into the fastening hole 156 by slightly rotating the connecting rod 131, mounting the connecting rod 131 is completed.

(37) The stopper 158 may be formed on the end of the coupling tube 154 and a protrusion having a height to cover a rear end of the coupling tube 154 may be formed in the lower body 112 to implement the stopper 158.

(38) Further, without using the elastic protrusion 137, the connecting rod 131 may be fixed by using a bolt 159 that penetrates the coupling pipe 154, the connecting rod 131, and the lower body 112 as illustrated in FIG. 8c. The connecting rod 131 may be fixed by using both the elastic protrusion 137 and the bolt 159.

(39) Meanwhile, as the coupling tube 154 into which the connecting rod 131 is inserted, an integrated pipe may be used and as illustrated in FIG. 9a, the coupling tube 154 may be implemented by coupling a fixture 154b capable of covering the connecting rods 131, 132, and 133 to the top of a rod seating portion 154a formed in the circular connector 152 to be concave.

(40) Since a structure in which three rod seating portions 154a are formed in the circular connector 152 is very simple in molding, the structure is still more easily manufactured than coupling the connector 152 to the pipe type coupling tube 154.

(41) The fixture 154b may be made of a plastic material like the connector 152 to be fused to the connector 152 or coupled through the bolt 159 as illustrated in FIG. 9b.

(42) As each of the connecting rods 131, 132, and 133, a carbon pipe which is small in weight and excellent in durability is preferably used, but the material thereof is not limited thereto.

(43) The floating bodies 121, 122, and 123 coupled to the respective connecting rods 131, 132, and 133, respectively are preferably made of expandable polypropylene (EPP) which is small in weight and excellent in durability, but the material thereof is not particularly limited thereto.

(44) As illustrated in FIGS. 10a and 10b, each of the floating bodies 121, 122, and 123 includes a through-hole 127 into which each of the connecting rods 131, 132, and 133 is inserted. A fixing cap 180 is preferably coupled to the end of the connecting rods 131, 132, and 133 at an opposite side of the through-hole 127 so as to prevent the floating bodies 121, 122, and 123 from being removed after inserting the connecting rods 131, 132, and 133. Of course, an outer diameter of the fixing cap 180 needs to be larger than that of each connecting rod.

(45) The fixing cap 180 may be coupled to the end of the connecting rods 131, 132, and 133 by using a forced inserting scheme, screw-coupled to the end of the connecting rods 131, 132, and 133, or fixed through the bolt, and the like.

(46) In FIGS. 10a and 10b, an extension portion 128 is formed, in which the fixing cap 180 is inserted into one end of the through-hole 127 of each of the floating bodies 121, 122, and 123, but the present invention is not limited thereto.

(47) Implementing a spherical floating body by mounting two hemispheres on the connecting rods 131, 132, and 133 as illustrated in FIG. 10c is more preferable than manufacturing the floating bodies 121, 122, and 123 by an integrated sphere. The reason is that the hemisphere is easily kept and transported.

(48) Further, since the floating bodies 121, 122, and 123 are not limited to a globular shape, the floating bodies 121, 122, and 123 may be manufactured in various shapes. Accessories having various character shapes which may double amusement may be attached to each of the floating bodies 121, 122, and 123. Further, by considering that each of the floating bodies 121, 122, and 123 is distant from the boat body 110 by a significant distance, a rescue handle which a person who falls into water may easily grasp may be mounted on each of the floating bodies 121, 122, and 123.

(49) Meanwhile, the table 160 is fixed onto the bottom of the lower body 112. In the embodiment of the present invention, a pole 162 is fixed onto the bottom of the lower body 112 and a circular table 160 is mounted on the top of the pole 162. Since a fixing method of the pole 162 is not particularly limited, all coupling methods are available unless an immersion phenomenon occurs in the lower body 112. For example, the table 160 may be installed in such a manner that a coupling protrusion is formed at the center of the bottom of the lower body 112 and the coupling protrusion is inserted into the bottom of the pole 162 at the time of molding the lower body 112. A separate coupling member may be fused or coupled to the bottom of the lower body 112.

(50) The sunshade screen 170 may be installed by inserting the pole 172 into a hole formed at the center of the table 160. Since an installation method of the sunshade screen 170 is not limited thereto, the sunshade screen 170 may be fixed to the upper body 114. Since a material of the sunshade screen 170 is not also particularly limited, the sunshade screen 170 may be made of a stiff material such as a plastic or a in a parasol form.

(51) In the leisure boat 100 according to the embodiment of the present invention, since structures of the lower body 112 and the upper body 114, the seat 140, the circular coupler 150, and the like which constitute the boat body 110 are simple, manufacturing cost may be reduced by decreasing molding cost of the respective components and since vacuum molding is available, mass production is enabled. Consequently, the leisure boat 100 is publicly supplied by lowering a price of the leisure boat to significantly contribute to base expansion of water leisure populations.

(52) The preferred embodiment of the present invention has been described above, but the present invention is not limited to the aforementioned embodiment and transformation, modification, or substitution to various forms may be made.

(53) For example, in the aforementioned embodiment, each of three connecting rods 131, 132, and 133 is inserted and coupled into the coupling tube 154 of the circular coupler 150, but the present invention is not limited thereto.

(54) For example, the circular coupler 150 is omitted and each of the connecting rods 131, 132, and 133 may be fixed to the seating portion 112a of the lower body 112 through the bolt, and the like. Further, the pipe type coupling tube 154 may be coupled to the seating portion 112a of the lower body 112 and each of the connecting rods 131, 132, and 133 may be inserted and fixed into the coupling tube 154.

(55) In addition, when the lower body 112 and the upper body 114 are very rigidly assembled through the bolt, and the like, each of the connecting rods 131, 132, and 133 may be coupled to the upper body 114.

(56) Moreover, three connecting rods 131, 132, and 133 are installed in the horizontal direction in the drawings, three connecting rods 131, 132, and 133 may be installed to be inclined so that the boat body (110) side is high and each of the floating bodies 121, 122, and 123 is low.

(57) Besides, since the shape of the boat body 110 is not limited to a circular cylindrical shape as illustrated in the drawings, the boat body 110 may be manufactured in various plane shapes including a triangle, a quadrangle, a pentagon, a hexagon, an octagon, and the like.

(58) Further, the seat 140 may be integrally placed along the inner wall of the boat body 110 and multiple seats may be separately installed. Further, as illustrated in FIG. 11, multiple inward protrusions 114c are formed in the upper body 114 to partition the integral seat 140 so that one passenger seats each seat 140.

(59) In addition, in the leisure boat 100 according to the embodiment of the present invention, a motor propellant 190 is preferably used as illustrated in FIG. 1 for movement. However, since the present invention is not limited thereto, a paddle, a sail, or the like may be used.

(60) In addition, a battery is preferably used as power, but a solar-cell panel is installed in the boat body 110, the sunshade screen 170, and the like to obtain the power. Further, an engine using oil may be mounted to drive a propeller.

(61) Moreover, a light emitting means such as an LED may be installed so as to verify the position of the boat even at night. In addition, a GPS, a satellite communication facility, and the like for verifying the position of the boat and communication may be installed.

(62) Transformation, modification, or substitution to various forms can be made as described above and even when the transformation, modification, or substitution is made, the transformation, modification, or substitution is, of course, included in the scope of the present invention if the transformation, modification, or substitution includes the technical spirit of the present invention disclosed in the claims to be described below.
