Abstract

FIELD: transportation.

SUBSTANCE: proposed device for moving on water has two identical rigid floats with leg holders and propulsive blades. According to the invention, the floats together support the weight of the person on the surface of the water. The floats are joined to each other by two parallel joints from a rigid material using hinges with provision for movement of floats relative each other in a single plane. Movement of the device is achieved through alternate transfer of body weight from one float to the other. Each of the leg holders is on an axis, parallel the axis of the floats, with provision for turning by an angle of not more than 90 degrees in each side relative the vertical longitudinal plane of the float cross-section.

EFFECT: smaller size and improved stability of the device.

Description

The invention relates to devices that enable a person to walk on the surface of the water.

Such devices have long been known, they are constantly being improved, as evidenced by previously issued copyright certificates and patents.

Among the analogues of this invention include the technical solutions described in the patents:

- Patent of Russia No. 2107639, 03/27/1998, "Water-skiing".

- Russian Patent No. 2078712, 05/10/1997, "Water-skiing."

- US patent No. WO 9014869 from 12/13/1990, the "Device for movement on the water."

In “Water Skiing Skis”, Russian patent No. 2107639, 03/27/1998, two inflatable floats on a wire frame are connected by flexible ties, consisting of on-board cords, and equipped with stern and side washers with runner rings. Despite the presence of bonds between the floats in the present invention, structural rigidity is not ensured.

Russian patent No. 2078712, 05/10/1997, "Water skiing" is a device containing two floats with propulsive flaps. It includes two internal and two external guides along which two floats and two rowing devices with propulsive flaps move respectively. The work includes the arms and legs of a skier.

In this invention, the floats are interconnected by guides, however, the design as a whole is bulky and heavy.

US patent No. WO9014869 from 12/13/1990, the "Device for movement on the water." The device consists of two floats, the volume of each of which should ensure the buoyancy of a person; floats have propulsive flaps for braking in the opposite direction of movement, and mounts for the legs. Propulsive flaps are plates mounted on floats, taking a position parallel to the surface of the float when moving forward, and opening in a position perpendicular to the axis of the float with the effect of braking when it moves backward. Since the floats have no connections, the device cannot provide stability in the direction of movement, the skier consumes energy to maintain the parallelism of the skis.

As a prototype of the invention, the last of the listed patents was selected as the closest to the claimed solution in its technical essence.

The basis of the present invention is the creation of a device for walking on water (hereinafter “the device”) in such a structural embodiment of the floats, the connections between them and the leg mounts, which will provide a reduction in size and improved stability.

This problem is solved by reducing the volume and, accordingly, the buoyancy of the floats. According to the invention, unlike the prototype, each of the two floats has a buoyancy insufficient to maintain the weight of a person on the surface of the water. Only two floats together can hold a person’s weight on the surface of the water. This feature provides a significant reduction in the dimensions of the device.

Another direction of solving the problem is the use of a movable connection of the floats with two parallel rigid connections. Each of the connections with the help of hinges at the ends is attached to two floats. The connection provides the mobility of the floats relative to each other in the same plane and their parallelism to each other at any time. Floats can move ahead of each other, approaching, then moving away from each other by the length of the bonds. The bond length is selected depending on the step length. The use of the described bonds summarizes the buoyancy of the floats. Thanks to this connection, considerable forces of the skier are released, aimed at maintaining the parallelism of the floats during movement, increasing the stability of the structure.

As a result of reducing the buoyancy of the floats and the introduction of parallel bonds, it becomes possible to apply a fundamentally new way of moving the device by alternately transferring body weight from one float to another. With this method of movement, in order to maintain parallelism in the plane of the foot support of each of the two fasteners and the water surface, according to the invention, a fastener having a rotation axis parallel to the axis of the float is used. The full angle of rotation of the mount is not more than 180 degrees and is limited by stops. For convenience, the angle defined by the stops can be adjustable. The axis of rotation of the fastener can be located either lower or higher than the plane of the foot support.

When moving in the aforementioned way, the float that counteracts the backward movement is completely under water. Therefore, in place of or in addition to the propulsive leaf, a saucer-shaped recess may be used on the end rear of each of the floats.

The above and other advantages, as well as features of the present invention will be more apparent after considering the following detailed description, accompanied by drawings, in which:

- Figure 1 - device according to the invention, front view.

- Figure 2 - device according to the invention, top view.

- Figure 3 is a device according to the invention, a section aa in figure 1. One of two floats is shown, increased.

- Figure 4 - diagram of the movement of the device, rear view.

- Figure 5 is a fragment, a mount with an axis of rotation above the plane of the foot support.

The device contains floats 1 (Fig. 1), on which axles 3 are fixedly mounted (Figs. 1, 2, 4). On the axles are fixed connection 2 (Fig.2, 4) with the possibility of rotation. The connections are made of rigid material with bushings at the ends. The sleeve on the axis is fixed to prevent axial displacement with a nut, cotter pin or any other method. On the floats below and / or on the side, propulsive flaps 7 are mounted on the axes of rotation 8 (Figs. 1, 3, 4). On the planes of the surfaces of the floats mounted legs, consisting of fixed supports 6 (Fig. 1, 3, 4, 5), axis of rotation 5 (Fig. 1. 3. 4. 5) mounted on them swinging elements with fasteners for the legs 4 (figures 1, 2, 3, 4, 5). The axis of rotation of the fastening can be located both below the plane of the support of the foot 5 (Fig.3, 4), and above it 5 (Fig.5).

In the rear end part of the floats are made cup-shaped recesses 9 (figure 1).

Consider the operation of the device.

In the initial position (device movement diagram, rear view of FIG. 4), the bonds 2 are perpendicular to the floats 1, (the floats are at maximum distance from each other). The right leg is straightened, the weight on the right float, and is under water, the left leg with the float is on the surface of the water and bent at the knee. The swinging fasteners are in the extreme left positions. Body weight is gradually transferred to the left (upper) float, while pushing it forward. The backward movement of the right (lower) float is extinguished by the opened propulsive leaf 7 and / or the rear end surface 9. In this case, the unloaded right float begins to float, pushing the left float forward by means of ties.

Body weight is distributed evenly between the floats. Both floats float, are in the position as close as possible to each other, the left float is ahead of the right, connections at an acute angle to the axes of the floats. The mounts are in the middle position between the two extreme points.

The weight is completely transferred to the left (front) float, which begins to sink, the propulsive sash prevents its return stroke; ties and pull the right float forward until the floats occupy the opposite position to the original: the right float above, on the surface, the bottom left, body weight on it, the links are perpendicular to the floats, the mounts are in the stop, in the extreme right positions.
