WATER SKI (VARIANTS) Russian patent published in 2019 - IPC B63B35/81 

FIELD: satisfaction of vital human requirements.

SUBSTANCE: invention relates to devices for movement on water and can be used in sport and pleasure water-skiing. According to the first version, water skis comprise a pair of skis fastened together by fasteners in the form of a platform from a plate and mounted fixed hitch behind the skis of the drive floating body including a low-power motor, a flexible power control connection of the impeller. Skis are connected to each other also by two pairs by parallel links from rigid material in the form of an angle section of aluminum with crossmembers, with provision of ski mobility by means of use of low-power impeller propulsor in the form of installed pressure device in compressor mode and creating hydrodynamic jet coming out of impeller nozzle. Device is made as independent buoyancy from disk-shaped body and with tightly enclosing annular chamber in the form of closed toroid filled with gas, and impeller nozzle is arranged on the bottom of disk-shaped body in rear part. Braking of device is carried out by fixing transverse inclined with bent lateral walls consisting of following one after another along length of skis and fixed on bottom of transverse axes, as well as a source in the form of forced supply of air under pipelines under the ski bottom for creation and maintenance of inclined plates in a vertical plane in water. Said transverse plates with bent lateral walls (edges) are made with possibility of their opening and folding with attachment to the bottom by their rotation around their transverse axes located on the ski bottom. According to the second version, water skis are included for braking and turning the device by fixing flaps fixed on fixed bars to fixed sideways skis, and turn of leafs by means of connection of shutter axles by two tie-rods with ski steering wheel arranged on plate fastening platform with possibility of deviation of column axis to the right and to the left from vertical axial plane of skis.

EFFECT: possibility of stable and controlled movement, increased speed and simplified performance of water skis.
