Through the embodiment shown in Figure 1, in the case of the buoyancy board according to the present invention, it can be seen that it consists of a main body 10 and the spin body 20, which are two separate parts.

On the other hand, the spin body 20 is mounted in a structure that is rotated with respect to the main body 10, the structure thereof can be confirmed later through FIG.

The main body 10 is made of a material having high buoyancy, such as a polymeric resin foam such as compressed styrofoam, or a tubular board filled with air, and an inner material of urethane foam or PVC foam, an outer shell of glass fiber, and a resin. Known materials such as surfboard materials made of composites made of ash may be applied to the main body 10 of the present invention, and other well-known buoyancy tool materials may also be applied without limitation.

The paddle 30 is mounted under the main body 10, and the paddle 30 is dynamically connected to the above-described spin body 20. Therefore, when the spin body 20 rotates, the paddle 30 also rotates. Detailed power transmission mechanism will be described in detail later with reference to FIG. 3.

Theoretically, the paddle 30 may be configured to rotate 360 ° according to the rotation range of the spin body 20. The rotation angle range of the paddle 30 is constant for maintaining balance and stable movement on the water surface. Is preferably limited.

The paddle angle limiting means to enable this, in the present embodiment, the fastening hole 15 formed in the lower surface of the main body 10, and the angle limiting projection 14 is inserted into and fastened to the fastening hole 15 We propose a paddle angle limiting means consisting of.

The angle limiting projection 14 is located on the path of the paddle 30 to limit the rotation angle of the paddle 30, as shown in Figure 2 in a symmetrical position on the lower surface of the main body 10 Each paddle 30 is preferably configured to maintain a balanced range of rotation.

Furthermore, by forming the fastening holes 15 to which the angle limiting protrusions 14 are fastened to various positions on the rotation path of the paddle 30 as shown, the paddles may be changed by changing the fastening position of the angle limiting protrusions 14. It is also preferable to comprise so that the rotation angle limitation range of (30) can be changed.

Meanwhile, through FIG. 2, the paddle 30 is powered from the spin body 20 via a power transmission unit consisting of a first sprocket 51, a second sprocket 52, a chain 53, and the like. It can be confirmed that the structure is received, there are a number of advantages of such a structure, among the first to mention, the center of rotation of the spin body 20 in terms of maintaining the balance of the buoyancy board in the center of the buoyancy board While it is desirable to position it, it is desirable that the paddle 30 is located close to the tip for imparting even propulsion throughout the buoyancy board.

Therefore, such a structure has an advantage of facilitating the construction of a structure for transmitting power to the paddle 30 is located close to the front end of the buoyancy board through the power transmission unit.

FIG. 3 is an exploded perspective view of a buoyancy board for playing in water having a propulsion device according to a preferred embodiment of the present invention, and clearly shows the configuration of a power transmission path from the spin body 20 to the paddle 30 by looking downward. To indicate.

Power by the rotation of the spin body 20, the upper end is fixed to the spin body 20, the main body 10 via the through hole 40 through the upper and lower surfaces of the main body 10 It is transmitted to the lower structure by the rotary shaft 55 is exposed to the other end of the lower end.

In the embodiment of FIG. 3, the other end of the rotation shaft 55 is directly fixed to the first sprocket 51, which is a component of the power transmission unit for transmitting power to the paddle 30.

The sprocket is also called a chain gear, and is a kind of gear that can transmit rotational force to another sprocket at a relatively distant position via the chain 53.

For the reason described above with reference to Figure 2, the paddle 30 is located in the rotatable structure in the lower end of the buoyancy board according to the present invention, the first sprocket 51 is a through hole 40 and the rotating shaft 55 Located in the lower portion of the center of the buoyancy board is located, the second sprocket of the distal end of the paddle 30 is fixed to the rotational force transmitted from the spin board 20-the rotating shaft 55 via the chain 53 ( 52).

As the paddle 30 is fixedly coupled to the lower surface of the second sprocket 52 in an integrated structure as shown in FIGS. 2 and 3, the left and right repetitive rotational movements of the second sprocket 52 are performed. Perform the rowing movement of the sector locus by.

Therefore, the spin board 20 is repeatedly moved left and right at the upper part of the main board 10, and the rowing movement of the paddle 30 is started at the lower part of the main board 10, thereby causing buoyancy. The board will move forward.

On the other hand, in order to smoothly rotate the rotating shaft 55 in the through hole 40, the rotating shaft bearing 56 is shown between the inner surface of the through hole 40 and the rotating shaft 55 as shown in FIG. It is preferable to interpose.

In addition, it will be clearly understood that the detachable structure of the angle limiting protrusion 14 and the plurality of fastening holes 15 described above with reference to FIG. 2 is illustrated in FIG. 3, in which the angle limiting protrusion 14 is separated. . Through this structure, as described above, it is possible to efficiently limit the rotation angle of the paddle 30, the range of the rotation angle limitation can be freely changed according to the user's body size, body control ability and the like.

On the other hand, another advantage of configuring the power transmission portion as shown between the spin body 20 and the paddle 30 will be described.

In addition to the above-described advantages of transmitting power to positions spaced apart from each other, a power transmission means such as a gear including a sprocket may perform a function of amplifying or reducing a force transmitted from an input unit to an output unit according to a situation. .

In general, in the case of the reduction gear structure, the rotation speed at the output is reduced compared to the rotation speed at the input, but the output itself is increased.

This is achieved by increasing the diameter of the gear located in the output section relative to the diameter of the gear located in the input section, or by increasing the number of interlocking gear peaks. By combining the structure, the paddle 30, which is rotated at the same time even when the spin board 20 is rotated with a small force, can be configured so that a relatively strong force is output to obtain a high propulsion force.

This means that even a buoyancy board that exhibits a strong propulsion force can be easily driven with a small force, and although not shown in the accompanying drawings showing a preferred embodiment of the present invention, a plurality of switchable switch as in a multi-stage gear bicycle. By having the plaques, a power transmission configured to allow a gear change can also be applied to the buoyancy board of the present invention.

Figure 4 is an exploded perspective view of the buoyancy board for playing with water according to a preferred embodiment of the present invention from the top direction.

4 illustrates a configuration of the locking jaw 25, which consists of two sides, the left locking jaw and the right locking jaw, which are detachably configured to freely change the mounting position on the spin body 20.

As described above, the locking jaw 25 has a structure that protrudes onto the upper surface of the spin body 20 to prevent slippage during the rotation operation of the spin body 20 and to facilitate the rotation operation.

In addition, as shown in the figure, it is preferable to have a structure in which the left locking jaw and the right locking jaw are arranged side by side at a predetermined interval so that both feet can be caught on the respective locking jaws 25 in the passenger's standing position. In order to be in a comfortable posture according to the body size, the mutually spaced width of the two locking jaw 25 is preferably configured to be removable by moving using the fastening means 22.

On the other hand, between the upper surface of the main body 10 and the lower surface of the spin body 20, that is, the surface facing each other, it is shown to minimize the friction caused by the contact between the surface and the surface during the rotation of the spin body 20 It is preferable to interpose the bearing means 16 as described above.

In the present invention, the bearing means 16 is a term that means a means having a sphere or a cylindrical body that can rotate in accordance with the slide movement of the surface, in the embodiment shown in the figure the bearing means 16 is a spin body It consists of the structure of the rolling wheel which rotates side by side in the rotational direction of the (20).

5 to 6 is a view showing the operating state of the buoyancy board for playing with a propulsion device according to a preferred embodiment of the present invention, Figure 5 is a perspective view from the top, Figure 6 is a view of the spin board from the bottom A perspective view showing the paddle movement according to the movement.

As shown in FIG. 5, the spin body 20 is slidably rotated on the upper surface of the main body 10 with the aid of the bearing means 16.

Structurally, the spin body 20 can be rotated 360 degrees with respect to the main body 10, but the rotation angle is limited within a predetermined range by the paddle angle limiting means described above. In this embodiment, the angle of rotation is limited by the paddle 30, the paddle angle limiting means consisting of the angle limiting projection 14, the fastening hole 15, which is mounted on the lower surface of the main body 10, The means for limiting the rotation angle is to form a specific structure on the upper surface of the spin body 20 and the main body 10 (for example, to prevent the protrusion of the spin body 20 during rotation). It may be made in various ways (such as a blocking means on the main body 10).

Meanwhile, in FIG. 6, it is possible to check the movement of the paddle 30 rotated together by the repeated rotational movement of the spin body 10 as in FIG. 5. In addition, the structure in which the rotation range is limited by the angle limiting protrusion 14 protruding on the rotation path of the paddle 30 can also be clearly understood.

5 and 6, the buoyancy board according to the present invention obtains thrust by how the paddle 30 pushes water when the spin body 10 is repeatedly rotated left and right. Can be clearly understood. In addition, it also describes how the direction can be changed when moving on the surface using the buoyancy board according to the present invention.

As shown in the drawing, when the spin body 10 is rotated to the left and right to obtain the driving force while the paddle 30 pushes the water to the left and right, the main body 10 moves forward as a whole, while the front end thereof is rotated. Depending on the left and right will be inclined little by little.

When the same rotational force of left and right is applied equally, the buoyancy board according to the present invention, on the average, advances in a straight line in spite of the repeated tilting of the tip portion, but the rotational force of either direction, for example, the left direction, is applied. When the force is strongly applied (rotated momentarily strongly) and the vehicle continuously performs the operation of weakly applying the turning force in the right direction, the buoyancy board according to the present invention gradually moves to the left side.

Using this principle, when using the buoyancy board according to the present invention, it is possible to move on the surface by obtaining a driving force by the magnetic force without the help of external force, as well as to move in the desired direction without a separate steering means Become.

As described above, the present invention has been described with reference to the drawings in accordance with a preferred embodiment, but the present invention is not limited to the configuration and operation according to the embodiments shown and described. Rather, those skilled in the art will appreciate that many modifications and variations of the present invention are possible without departing from the spirit and scope of the appended claims. Accordingly, all such appropriate modifications and changes, and equivalents thereof, should be regarded as within the scope of the present invention.
