However, the configuration described in the embodiments and drawings described below are only the most preferred embodiment of the present invention and do not represent all of the technical idea of the present invention, which can be replaced at the time of the present application It should be understood that there may be various equivalents and variations.

As shown in FIG. 1, the air-injection surfboard 100 of the present invention includes a hollow portion 110, an upper sheet 123, a lower sheet 124, a hollow portion side sheet 121, and It includes an outer member including an outer side sheet 122, the inner space member 210 is present in the outer member as shown in FIG.

Board 100 of the present invention is characterized in that the air is injected through the air injection unit 130 to obtain buoyancy. Therefore, it is possible to manufacture a surfboard for lighter than conventional wood or polyurethane material. In addition, when the board is not used, removing the injected air may reduce the volume of the board according to the type of outer material applied to the board.

The outer member according to the present invention may include an upper sheet 123, a lower sheet 124, a hollow side sheet 121, and an outer side sheet 122, and may further include a decorative member or a functional member. have. Such an outer material keeps the outer shape of the board 100 and prevents water from penetrating into the board and air from leaking to the outside.

The outer member according to the present invention may be formed so that the front end portion of the board is inclined upward. If the front end of the board is inclined upward, the surface hitting the water wave during surfing is reduced, thereby facilitating the progress.

Since the board 100 of the present invention has to be filled with air to have a sufficient pressure to support the weight of the person occupied on the board, select the outer material that can support this pressure. In addition, the outer member according to the present invention may be made of a flexible material that can reduce the volume of the board, for example, can be folded if the air inside the board 100 is removed. Optionally, according to the present invention, the top sheet 123, the bottom sheet 124, the hollow side sheet 121 and the outer side sheet 122 may all be made of the same or different materials.

For example, the outer material may be made of one or two or more selected from the group consisting of PVC, polyester, and nylon as a material having shape maintaining performance, water resistance, and / or flexibility, but is not limited thereto.

In addition, the board 100 of the present invention is characterized in that the hollow portion 110 is formed. Surfboards are used by people on board and in balance. By the way, in the case of using a flexible outer material in the present invention, it may be difficult to maintain the balance. Therefore, the board 100 of the present invention achieves easy balance maintenance through the hollow portion (110). Specifically, the hollow part 110 according to the present invention serves to disperse the pressure applied to the board 100 to its side when a person rides on the board in the water to prevent the weight from being pulled to either side. can do. Thus, the board is not easily flipped even when a person boards and is easy to balance in the water.

Position or size of the hollow portion 110 of the present invention may be variously adopted depending on the size and use of the board (100). That is, the board will not be deformed even if a person rides, and the skilled person will be able to determine an appropriate position and size within a range that can sufficiently exert the pressure dispersing effect and expect the hollow portion forming effect. For example, the hollow portion for obtaining the desired effect of the present invention as described above in a general surfboard may be 10 ~ 60 cm in diameter, but is not limited thereto.

In addition, the hollow portion 110 may be formed to have an inclination with respect to the front side like the front end of the board. This is because when the board proceeds in the water phase, the hollow side sheet defining the hollow part also hits the water like the front end of the board, so if the wall surface of the hollow part is inclined with respect to the direction of travel as with the front end of the board, This is because the bumping surface is reduced, which makes the progress easier.

Board 100 of the present invention has an internal space member 210 therein. 2 is an exploded perspective view schematically showing the relationship between the inner space member 210 and the outer member according to the present invention. In addition, FIG. 3 is a side cross-sectional view of the line AA ′ of FIG. 1 schematically showing an inner space member 210 provided inside the outer member. The inner space member 210 is formed of an upper surface 211, a lower surface 212, and a support line 213 connecting the upper surface and the lower surface. In addition, the upper surface 211, the lower surface 212 and the support line 213 is woven into the fiber is formed integrally. As such, when the upper surface 211 and the lower surface 212 are connected to the support line, when air is injected into the upper surface 211 and the lower surface 212, the upper surface 211 and the lower surface 212 are curved upward and downward, respectively, and do not swell. It can be maintained. In addition, in the present invention, since the upper surface 211, the lower surface 212 and the support line 213 are integrally formed, the support line 213 may more firmly support the upper surface 211 and the lower surface 212.

In order to integrally form the inner space member 210 of the present invention, it is preferable to weave the fibers. The weaving method can be adopted without limitation as long as it is suitable to form the inner space member 210 integrally, for example, but not limited to the knitting method.

As a fiber that can be used, a fiber having excellent tensile strength can be selected that can withstand the pressure of the air injected therein. For example, it may be selected from polyester fibers or nylon, but is not limited thereto. In addition, in order to manufacture a strong internal space member 210 that can withstand the pressure of air, the fiber may have a sufficient fineness, in consideration of the use and economics of the board can be adopted an appropriate fineness. The fineness of the fiber may be, for example, 100 to 500 denier, but is not limited thereto.

The inner space member 210 of the present invention may further include a coating layer (not shown) on the outer surface in order to prevent the outflow of the injected air and to add firmness of the fibers forming the inner space member. In addition, such a coating layer can improve the adhesion with the outer material. The coating layer according to the present invention may be formed by applying a resin such as PVC to the outer surface of the inner space member 210 and drying it.

As shown in Figures 1 to 4, the board 100 of the present invention may further include an additional decorative member or functional member of the present invention.

For example, the rubbing portion 140 may be selectively installed to protect the lower sheet 124 and further increase the firmness and stability. In addition, by inducing the flow of water when surfing can add a sense of speed and stability. The rubbing unit 140 may be made of a rubber molding.

In addition, by selectively installing the kill unit 150, it is possible to further increase the stability so that the board 100 is not easily flipped when surfing. In addition, depending on the installation position, there are other additional effects, such that when installed in front of the rotation is improved, and installed in the rear can increase the straight speed.

In addition, the side handle 160 may be selectively installed to easily balance the side handle 160 using the side handle 160 when boarding in a prone position on the board.

In addition, the transparent window 161 may be selectively installed to easily check the state inside the board. Through the transparent window 161 can check the state of the board and the inner space member 210 before or during use to enable more safe use.

In addition, by selectively installing the traction ring 162, by connecting a string there may be convenient to carry the board 100 in the ground or water.

In addition, a PVC fabric 163 as a decorative member may be attached onto the top sheet 123 to protect the top sheet and add color to increase the commercial value of the board.
