Hereinafter, preferred embodiments according to the present invention will be described in detail.

First, Figures 1 to 5 are views of a water walker according to the present invention.

As shown, the present invention has an elliptical curve in the front, and is configured to include a floating body 10 having a horizontally closed rear after being formed in a straight shape toward the rear.

The floating body 10 applied to the present invention is an embodiment, and may be manufactured using a material having buoyancy but using an air tube or using a material such as styrofoam that floats well in water, to prevent damage and withstand the weight It must have considerable buoyancy and robustness.

The floating body 10 has sufficient buoyancy while being horizontally separated to consist of an upper fluid 12 and a lower fluid 14, and the upper and

lower fluids

12 and 14 separated vertically are each in a plurality of bodies. By installing the string 16 of dogs, the upper and

lower fluids

12 and 14 are bundled with the string 16 in a state where they overlap to form one floating body 10 .

The present invention is to install the floating frame 20 to perform the role of a skeleton supporting the floating body 10 as above, the floating frame 20 has a shape similar to the floating body 10, the upper and lower fluid It is installed by being sandwiched between (12) and (14), and after positioning the floating frame (20) between the upper and lower fluids (12) and (14), it is fixed so as not to move using a string (16).

Here, in the case of manufacturing the floating body 10 as a single structure, the floating frame 20 should be manufactured so that it can be located in the inner center during the manufacturing process of the floating body 10 having buoyancy, in this case the floating frame (20) and the floating body (10) is not separated.

The floating frame 20 has the same shape as that of the floating body 10, and is made of hollow metal or synthetic resin pipes, rods, etc., but it is sufficient if it can withstand a sufficient load.

The present invention installs the rotating frame 30 in the horizontal direction at the center of gravity of the floating frame 20, but both ends of the rotating frame 30 are fixed to the inside of the floating frame 20, the floating frame 20 ) and the rotating frame 30 are fixed using welding or a separate fixing means.

The pivot frame 30 is divided into left and right across the center of the pivot frame 30 vertically, and a support frame 40 fixed to the longitudinal center of the front and rear of the floating body 10 is installed to install the floating body. The frame of (10) is made to withstand a sufficient load.

The rotation frame 30 and the support frame 40 as described above are also made of a hollow pipe, rod, etc. made of a metal material, synthetic resin, etc. to generate a buoyancy force while having a certain strength and rigidity.

On the other hand, in the present invention, a rectangular footrest 50 is installed on both sides of the rotating frame 30 divided into left and right by the support frame 40, but the footrest 50 is sufficient to withstand the load of the user placing the foot. On the other hand, since it generates propulsion, it must be made of a fairly strong material.

The front of the footrest 50 and the front of the floating body 10 or the floating frame 20 are connected to the elastic body 55 so that when the footrest 50 is pressed, the elastic body 55 is stretched to have an elastic force, and the footrest ( If 50) is not pressed, the footrest 50 is lifted by the elastic force of the elastic body 55 .
