Water skis with flaps to move around while walking »

3s "it is known that water skis are used to practice a water sport · Water skis are small boat bodies» with the help of which the practitioner can move while standing on the water surface · Movement is mostly effected by paddling or also by stucking · This sport is considered to be pure Operated in summer sports or as summer sports for ^ Lm.Skiing on the snow.However, the type of application of water skiing differs considerably from that of snow skiing in that only the work of the arm and upper body muscles is used for port movement and not the walking movement, as is the case with snow skiing ά, βτ When is used as a drive for movement. Movement with the help of ύοτι water skis is therefore not as well adapted to the natural body movement as snow »Skiing · It is not least due to this fact that water skiing is not practiced to a great extent ·

The following invention is based on the idea of "giving water skiing the same or a similar mechanism of movement" as is inherent in snow skiing. but preferably several expansion bodies »eg in the form of a flap» provided »which» are attached to the hull in pivot bearings and can either be attached to the hull or spread apart from it by hydrodynamic forces . According to drawing 1, the hull is “the i. α. made of a material with a density greater than 1 g / cm * »a torque occurs» that the flap is in the spread position: preferably so that the surface of the flap protrudes at an angle of 90 ° from the tangential plane of the hull in the pivot bearing of the flap - is rotated. During the backward movement or when a backward movement component occurs, a torque caused by the liquid forces pushes the expansion flap into the prescribed expanded position according to the drawing

de Triimnkante becomes a bend of the free / rotating hinge · opposite broad side of the expansion flap as shown in the drawing 2 understood »Its purpose is the flow of liquid between the hull and the flap and thus the necessary pressure distribution to produce the desired torque for the flap movement: to be generated »in the apprsispositiont by abutment on the hull according to the drawing 5 is set »give the expansion flaps to the ski a large form resistance · When the ski is moving forward, the flaps are tightened by the liquid forces in the discussed above. Drainage smoothly placed on the hull of the boat » and the form resistance goes back to a small amount "This measure makes it possible" the two as skis hull used in the course of the nozstal stride to move against each other »Here the STasser resistance at Backward movement of one hull large · that of the forward movement small, the walking movement results in a forward movement of the entire unit (skier + water skier) »

"In addition to this training of the skis for the useful use of leg movement, the natural pendulum movement of the ax can still be used appropriately for work performance for locomotion and thus be adapted to snow skiing" that on sticks - corresponding to sticks in snow skiing - smaller, flat * boat-like floats , for example a pram in UMT Foxm, which in turn equips them with the expansion flaps described above.
