Description

The device relates to the field of production of watercraft intended for entertainment and sports and can be used as a means to move on the water surface due to the muscular efforts of a person for training skiers, as well as for relaxing on the water.

The main requirements for devices for moving on the water surface due to the muscular efforts of a person are ease of use and manufacture, small weight and dimensions. In particular, for water skiing it is an opportunity to train athletes-skiers in the summer. Moreover, the nature of the athlete’s movements on water skiing should be as close as possible to the nature of his movements during winter skiing.

Moving on the water surface, in the development and implementation of appropriate equipment, may be a new promising sport.

Known water skiing, consisting of a body with a hole for installing the legs and the repulsion mechanism in the form of a rotary plate (see patent for utility model RU 106219 U1, publ. 10.07.2011).

A disadvantage of the known device is the low efficiency of the repulsion mechanism that does not provide a powerful reference shock.

A device for moving on a water surface is known, including skis and poles in the form of sealed floats with a repulsion mechanism in the form of plates mounted with the possibility of deflection to the side opposite to the direction of ski movement, while the ski floats are equipped with keels and bushings for installing legs of a rest chair ( see patent for utility model RU 74367 U1, publ. 06/27/2008).

A disadvantage of the known device is the complexity and adaptability of the design. The fastening of the plates to the hollow body of the floats may be the reason for their depressurization. In the case of mounting plates to integral floats made of light porous materials, for example, foam, this mounting is also not reliable. The operation of pivotally mounted rotary plates in an aqueous medium requires, for their return to a vertical position, the manufacture of plates from materials with a significant specific gravity or force, for example, due to springs. The requirement for reliable operation of the joints in the aquatic environment complicates their design. In General, the proposed repulsion mechanism significantly complicates the design of the known device and reduces its buoyancy.

The technical task of the device is to simplify the design of skis, increase the efficiency and reliability of their work and simplify the technology of their manufacture.

The task is achieved by the fact that in the proposed device, including skiing in the form of sealed floats with a keel and bushings for installing legs of a high chair for rest, sticks in the form of floats with pivotally mounted rods, the repulsion mechanism, according to the invention, the mechanism of repulsion of skis and poles is made in in the form of transverse riffle floats, separated by through recesses from the body of the floats, the profile of which in the keel plane of the floats is in the form of a right triangle, in which one leg is located vertically the flute plane, the second leg lies at the level of the outer surface of the bottom of the floats, and the hypotenuse lies on the inclined plane of the flute, which is facing the translational movement of the skis, while the vertices of the triangular profile of the recesses are at the intersection of the vertical and inclined planes of the flutes and are not lower than the level of the waterline floats loaded with their own weight. Stick floats can be equipped with a keel. The conjugation of the lines forming the profile of the riffles can be performed along an arc of a circle. The contour of the vertical plane of the grooves can be made in the form of a rectangle or a semicircle. Ski floats may have a recess for installing the legs, the contour of which in the top view is symmetrical to the vertical passing through the center of gravity of the ski. All floats of the device can be connected by a flexible connection.

The device has the following differences from the prototype:

- the mechanism of repulsion of skis and poles is made in the form of transverse flutes of the flutes separated by through recesses from the body of the floats, the profile of which in the keel plane of the floats is in the form of a right triangle in which one leg is located on the vertical plane of the flute, the second leg is at the level of the outer surface of the bottom of the floats , and the hypotenuse lies on the inclined plane of the riffle, which is facing the progressive movement of the skis;

- the vertices of the triangular profile of the recesses are located at the intersection of the vertical and inclined planes of the grooves and are located not lower than the level of the waterline of the floats loaded with their own weight;

- stick floats can be equipped with a keel;

- conjugation of straight lines forming a through profile of the riffles can be performed along an arc of a circle;

- the contour of the vertical plane of the grooves, can be made in the form of a rectangle or a semicircle;

- ski floats may have a recess for installing the legs, the contour of which in the top view is symmetrical to the vertical passing through the center of gravity of the ski;

- all device floats can be connected by flexible connection.

This will simplify the design of the device, increase the reliability of its work and simplify the technology of its manufacture.

A comparative analysis of the claimed invention and the prototype reveals the presence of distinctive features of the claimed device in comparison with the closest analogue, which allows us to conclude that the proposed technical solution meets the criterion of "novelty."

In the patent information fund that we reviewed, no technical solutions with the indicated differences were found, as well as technical solutions with the specified set of distinctive features.

The proposed technical solution is applicable and will be used to create devices for sports purposes, as well as devices for entertainment and recreation on the water.

The design of the device is illustrated by the following materials:

FIG. 1 is a diagram of a device for moving on a water surface, top view;

FIG. 2 - ski, side view;

FIG. 3 - stick, side view;

FIG. 4 is a view A in FIG. 1, options;

FIG. 5 - options for performing riffles.

Skis for water movement (Fig. 1) include skis 1 in the form of sealed floats with recesses 2 for installing the legs (Fig. 2) and poles 3 in the form of sealed floats with pivotally mounted rods 4 with mounts 5 for human hands (Fig. . 3). On the bottoms of ski floats and stick floats, there are keels 6 and a repulsion mechanism made in the form of riffles 7 separated by through recesses 8, the profile of which in the keel plane of the floats is in the form of a right triangle, in which one leg is located on the vertical plane 9 of the riffle 7, the second leg lies at the level of the outer surface of the bottom of the floats, and the hypotenuse lies on the inclined plane 10 of the flute 7, which is facing the progressive movement of the skis. The top of the triangular profile of the recess, located at the intersection of the vertical and inclined planes of the flutes 8, is not lower than the level of the waterline of the floats. Position 11 marked sleeves for installing a chair for relaxing on the water.

In FIG. 4 shows the configuration options of the vertical plane 10 of the flute 8: a - rectangular, b - semicircular.

In FIG. 5 shows embodiments of the riffles 7, depending on the type of conjugation of the straight lines forming the profile of the riffles: а - mates forming corners on the edges of the riffles; b - mates forming a profile of corrugations with rounded faces.

The device operates as follows.

The athlete gets up on skis 1 from the pier from the “sitting” position, skis 1 and poles 3 are afloat at a depth that ensures that keels 6 do not contact the bottom of the pond. In the athlete’s hands are rods 4 with fastenings 5 of sticks 3, on which he rests, while maintaining balance, is repelled during movement.

Water movement is due to the efforts of hands with sticks 3 and legs located in the recess 2 of the skis 1. The recess 2 can be equipped with fastening bare feet or athlete’s shoes (not shown in Fig. 1 and Fig. 2).

The repulsion of skis and poles occurs due to the presence in the soles of ski floats and rifle poles 7, separated by through recesses 8 with a vertical 9 (push) and inclined 10 planes.

Floats of skis 1 and poles 3 can be made: inflatable; frame - with waterproof sheathing; whole - from light porous material. In FIG. 4 shows embodiments of the vertical plane 9 of the flute 8, determining the cross-sectional configuration of the ski floats and poles: pos. a - with a box bottom, pos. b - with a semicircular bottom.

The location of the vertices of the triangular profile of the recesses 8 not lower than the level of the waterline of the floats loaded with their own weight guarantees a powerful support push for the skier due to the maximum possible increase in the push area of the skis and poles, determined by the total area of the vertical planes 9 of the flutes 7 under water.

In FIG. 5 shows possible technological profiles of riffles: pos. a - in the manufacture of floats from a solid material, pos. b - in the manufacture of inflatable or frame floats.

The flexible connection of all the floats of the device simplifies the transportation of a set of skis and poles to the shore in case the athlete falls into the water. The length of the flexible connections does not interfere with the relative movement of the ski floats and poles when the athlete moves on the water surface.

The device is convenient in operation, provides the ability to maneuver, buoyancy and safety with low weight and dimensions. Skis with dimensions of 180 * 20 * 25 cm hold a person weighing 120 kg. The presence of the sleeves 11 allows you to install in them the legs of a light folding chair, fastened behind the skier's belts, turning the ski floats into a catamaran for a period of stopping movement. In the manufacture of inflatable ski floats and poles, the device can be folding.
