DE3002618A1 - Pair of hydro-skis for walking on water - keeps walker above water by its own buoyancy and skis are shaped to exert greater resistance to rear - Google Patents

Abstract

The hydroski is designed to permit walking on water. The hydroski keeps the water walker above the water by its own buoyancy and it is made to exert great resistance in the water towards the rear which makes it possible to push forward with the other hydroski which has little water resistance in the forward direction. The shape of the hydroski makes it impossible for one ski to undercut the other and also allows any water running over the top of the ski to run down its sides. Along the middle of the ski upper side there is a device to insert the skier's foot fitted with holding devices for the shoe.

Title: gydroski Field of application: The invention relates to a device for getting around on the water.

Purpose: The hydroski allows you to go about in natural gaits (Walking, running) to move on the water.

State of the art: There is / is a means of locomotion on the water me rocks, boats, surfers and windsurfers.

Unless machines or wind provide the driving force, will muscle strength for locomotion using paddles, belts, paddle wheels, stacks, etc.

transfer.

Criticism of the state of the art: watercraft with wind as the propulsion force Can't drive when there is no wind. You can go against the wind with one goal can only be achieved by long detours with a corresponding loss of time, with muscle power operated vehicles are partly the most powerful ones made for locomotion Muscles not used (e.g.

When rowing, on the other hand, you sit with your back to the canoe Direction of travel, so that it is difficult to see where you are going and what you are in Even with sailing boats, visibility in the direction of travel is severely restricted.

Motorboats are increasingly being perceived as a nuisance on many bodies of water. Nor do they give people the physical necessary to keep them healthy Movement possibilities. They also need valuable, increasingly scarce ones MATERIALS TO DRIVE THE WATER SKI, too, can only be powered by an external engine Surfers have to struggle to swim out through the surf to take one suitable wave to be able to ride back again.

Task: The invention is based on the task of a new means of locomotion to create on the water that largely corresponds to the natural gait and does not have the disadvantages of the other modes of transport mentioned above has a special attraction for people, offers him a new experience.

Solution: This task is solved by the hydroski, which is designed in this way is that it gives the user (water strider) the necessary buoyancy when using it4 and the resistance in the water to push yourself forward in the desired direction can.

Hydroski Another embodiment of the invention: what is achieved is lndem the hydroski is so much lighter than water that it is the weight of the water strider at the desired height and the water only slightly in one direction of movement Offers resistance, while it offers high resistance in the opposite direction of movement There is resistance. This makes it possible to close in pairs with reciprocal movement using the hydroskier to put one in front, while the other one is required to do so Wasse: has resistance.

To increase the speed and also to use the arm strength, you can It is also possible to operate the slide or puller with the hands In addition, to use the wind power with a specially designed sail.

The hydroski can also be sociable with appropriate dimensions Can be used by 2 or more people.

Achievable benefits: The millennia-old desire to walk on water and being able to run is fulfilled with this invention. The hydroski caters for recreation, sport and occupation a new way of getting around on the water, which is largely the corresponds to natural locomotion in the country. It becomes a pleasantly springy one Walk because the water gives way elastically.

Extended compared to locomotion in boats in a deep seated position When walking upright, the field of vision increases considerably and creates the best possible Overview.

Description of exemplary embodiments l-Sin Hydroski consists of one about 2.50m long, about 30cm wide and about 15 cm high, coated with plastic Foam core that is bent forward so that it does not undercut when moving forward It is designed in such a way that it can hardly be seen horizontally when stepping forward Has resistance in the water. The top is slightly flattened on the sides, so The water that rinsed over it drains off as quickly as possible and without hindrance The foot insert is incorporated in the middle of the top.

The surface that plunges into the water has tongues that protrude bare back occupied when pushing the hydroski to this feeder when moving backwards however, the tongues spread apart and thereby have a considerable amount greater water resistance than when moving forward, which allows the other Skis are each moved forward.

2. The hydroski can also be made as a hollow body made of plastic, Netall or Made of wood.

Its volume and shape will continue to Hydroski the striding ability of the water striders and changed according to special requirements, as best suits the purpose. Another possibility is to use the To make hydroski inflatable from stiffened, thin, air-impermeable material (e.g. rubber, plastic, waterproof fabric). This would have advantages for storage and transportation.

Hydroskis can also be made from light wood that is impregnated will.

3. With the possibility of a large difference in water resistance Getting the opposite directions of movement can be done by immersing yourself in the water Instead of the tongues, the surface can also be occupied by bristles protruding backwards or also with a back pocket that folds up when moving forward and expand as you move backwards.

Another possibility is to build in water wheels, which are located in rotate in one direction (i.e. have no resistance) and block in the other, whereby a great resistance arises.

Also flaps that move in one direction of movement into the flow lie down and slope in the other at right angles to it, serve the purpose.

The flaps and water wheels can also be attached so that they can be reversed they can be used to brake and reverse the journey Direction changes can be facilitated.

Finally, the immersed surfaces can have fixed resistances be provided, which are lifted out of the water as you advance.

4. On the top of the Hydroakier there is the foot insert approximately in the middle It consists of a tread area for the foot r; t each with a bead upwards with several recesses lying one behind the other Central axis, in which a holding device depending on the foot size and other circumstances (Swell, load from sails, etc.) only locked in front or back can be.

The holding device is attached to a waterproof sneaker can also be incorporated into a shoe specially made for running in water Overuse (e.g. falling into water) freaks them out.

Another way of connecting the foot to the hydroski for high altitude Every shoe has to be locked in place at the front and back to create a firm connection to obtain.

a cap will be used for the lowest requirements Hydroski or a loop in the central area on the hydroski attached to the connection to be made by foot.

h 5. A slide that provides additional acceleration through arm work made possible, consists of an umbrella-like attached to the lower end of a stem Part that unfolds and spars against the water when it comes from above and When the water is pulled up, it folds up smoothly and have no resistance in the water. so it is possible to advance with this help.

In contrast to the sliding technology, it can also be used as an aid when running in water The Zeihteck nik can also be used, with the handle perpendicular to it Longitudinal axis, a curved blade attached, similar to a hoe, but made of light weight Material so that it floats; if you pull the handle, the leaf is immersed in the water one and gives the hold, if it is pushed forward, then it pushes out of the water and has no resistance, so you can use it to pull forward.

6. A special sail to use as additional wind power when running in the water Helping to use the hydroski is symmetrically shaped so that it alternates can be attached to one or the other hydroski. Since the water strider cannot move around the sail when tacking and jibing, the sail is reversed: each time the previous top of the mast becomes the base of the mast.
