SKIS FOR MOVEMENT ON WATER Russian patent published in 2019 - IPC B63B35/81 

FIELD: transportation.

SUBSTANCE: invention relates to production of water vehicles intended for entertainment and sports, and can be used as means for movement on water surface due to muscular man's efforts for training of skiers. Skis for water movement include skis in the form of tight floats with keel and sleeves for installation of legs of rest chair, floats in the form of floats with hingedly installed rods and a mechanism of repulsion. Mechanism of repulsion of skis and poles is made in the form of transverse to the floats of grooves separated by through recesses from the body of floats, the profile of which in the keel plane of the floats has the form of a right triangle, in which one leg is located on the vertical plane of the flap, the second leg lies at the level of the outer surface of the float bottom, and the hypothenuse lies on the inclined plane of the flap which faces the translational motion of the skis. Vertices of triangular profile of recesses are located at intersection of vertical and inclined planes of riffles and are located not below waterline of floats loaded with own weight.

EFFECT: simplified design of the device, increased efficiency and reliability of its operation and simplified technology of its manufacturing.
