All of the above devices (the so-called. "Floating ski") have a limited scope, since they are focused on moving a person through the water in alternating steps. To ensure the functioning of such devices, it is proposed to use recoil valves or blades. At the same time, for anti-recoil devices to work effectively, a long and sharp step is needed, which makes it difficult to maintain balance, hence the keels, the connections between the floats so that the legs do not move apart.

In ordinary skiers, even on hard surfaces, in rolled and icy areas, it is recommended to switch to simultaneous non-stop running (only with sticks), and it is much easier to lose balance on water.

The closest solution in technical essence and the achieved effect of its use to the claimed solution is the known design of a device for moving a person in difficult terrain according to the patent of the Russian Federation for utility model N 87991, B63B 35/81, 2008, containing two ski skis, a pipe and a solid frame, and the ski floats are made of light cylindrical material, hollow, filled with material with a low specific gravity and consisting of fore, central and aft parts, while the bottom of the bow is each the float ski is beveled towards the nose and makes up 1/3 of the length of the entire ski, in addition, the central part of each float ski is equipped with a foot mount so that the central axis of the foot recess is located along the vertical axis of intersection plane and perpendicular to the vertical plane and is the geometric center of the submerged volume of the ski-float, while the horizontal plane of attachment for fixing the legs is located at a height of at least 3 cm from the bottom of the ski-float , The end surface of the rear part is planar and carries the foot support portion fuktsii propulsor interacting with the medium, on its surface (water, snow, ice, soil, vegetation and the like) is moved person (user).

This device, although it allows for the movement of people through water, shallow water and wetlands, but has some significant limitations:

The cylindrical shape of the ski-floats does not allow people to move confidently on hard surfaces: ice, snow (crust) and earth.

The need to fill the internal volume of ski floats with material with a low specific gravity not only makes the design heavier, but also eliminates the possibility of using the internal volume of the ski float bodies for storage and transportation of useful loads, and also prevents the compact folding of the device for its transportation.

The need to lift the center of gravity of the device to a specific height specified by the design features above the level of the bottom of the ski-float reduces the stability of the device.

The need to mow the bottom of the bottom of the ski-float to the nose 1/3 of the length of the ski-float leads to a significant displacement of the legs back, and a long nose is inconvenient when using the device both in snow and in overgrown vegetation.

The task to which the claimed utility model is directed is to expand the arsenal of existing technical means related to further improving the efficiency of using the device to move a person through difficult terrain by increasing ease of use and stability (especially on a hard surface), simplifying its storage and transportation to the place of operation, as well as expanding its functionality and expanding the number of possible mobility media.

The proposed device for moving a person in difficult terrain, contains two - the first (left) 1 and second (right) 2 ski-floats (see Fig. 8).

In the first embodiment (see Fig. 1, 2, 3, 4, 5) of the proposed device, each of the ski floats 1 and 2 (see Fig. 8) has a hollow body 3 (see Fig. 2, 3), including bottom 4 (see Figure 3), side 5 (see Figure 2) and deck 6 (see Figure 1).

Case 3 (see Fig. 2, 3) is made of solid material, for example, from ABS plastic, glass or carbon fiber, polyethylene or their combinations, and its dimensions are determined by the weight of the person along with the load, height of the person and operating conditions.

In front (see Figure 4), the hull 3 of each ski float 1, 2 is made in silhouette close to the silhouette of the hull of the boat with a flat bottom (the so-called "punts").

On the bottom 4 (see Figure 3), made in the form of a wide ski from the lower (outer) side in the middle part, anti-recoil notches (not shown) and two longitudinal grooves 7 (see Fig. 3, 5) are made Stability device in the snow.

On the inner side of the bottom 4 there is a mount 8 (see Figs. 1, 5) for fixing the legs of a person of universal type for any shoes of the user. In this case, the attachment 8 should be installed so that the person’s center of gravity is shifted back relative to the geometric center (not shown) of the submerged volume of the ski floats 1 and 2 to prevent burying of the ski floats 1, 2 when the person is tilted forward and to facilitate exit human from water to ice or to land.

Deck 6 consists of three parts: bow 9 (see Figure 1, 9), middle 10 (see Figure 1, 9) and stern 11 (see Figure 1, 9). In the bow 9 and stern 11 parts there are corresponding airtight hatches 12 and 13 (see Figs. 1, 2, 9) that provide access to the hold for placement and storage of gear, catch, game, products, etc.

In the middle part 10 of deck 6 there is an opening 14 (see FIG. 3) for fixing the legs, which can be covered with a cover (not shown) of a waterproof fabric with quick-release rubber clips (not shown), fixed to the man’s lower leg and on the side 15 of the hole 14, which allows a person to quickly release his leg in an emergency.

The emergency stock of buoyancy can perform special lightweight inflatable elements (not shown), placed inside (in the hold) of the hull 3.

To ensure reliable movement, there is a mover driven by a person. At the same time, it is proposed to use original ski poles 16 (see Fig. 6) with voluminous supporting platforms (with positive buoyancy) as the propulsion device with manual transmission. “Legs” 17 (see Fig.6, 7) of a pyramidal shape, with a rectangular base, which, compared with the known designs of poles with support legs of a conical shape, allows you to put the stick 16 closer to the body 3 of the ski-float 1 or 2. The distance from the axis of the stick 16 to the front edge of the base of the pyramid of the foot 17 should be less than to the back (see Fig. 7), which allows less load on the front edge of the base of the foot 17 of the stick 16 when moving in the snow, and the smoothed corners of the foot 17 increase its wear resistance. In addition, the volume of the foot 17 can be relatively small and be less than 2.5 l, since during the loss of balance, short-term support on the base of the foot 17 is sufficient.

At the upper end of the stick 16, it is recommended to place a special spike 18 (see Figure 6), which serves as an ice ax / hook, for example, facilitating the movement of a person in hummocks in winter and when leaving the water for ice.

In addition, to facilitate access to the ice, it is proposed to use removable plates with spikes (the so-called "cats") 19 (see Fig. 2, 3), which are mounted either on belts 20 (see Fig. 2) through deck 6 or on latches (not shown in the drawing) aboard 5, and when using one “cat” 19 on a ski-float 1 or 2, it is better to place them at different distances from the nose for the convenience of crossing during movement.

To reduce the width of the ski-floats 1 and 2, the side 5 is made with a kink 21 (see Fig. 2, 4) at the level of the water line 22 (see Fig. 10), and the deck 6 is attached to the side 5 with detachable screw connections 23 (see 5).

To ensure the possibility of reducing the distance between the legs of a person, the bend 21 of the side 5 from the inner side of the closest parts of the hulls 3 of each pair of ski floats 1 and 2 should be more gentle than on the opposite, remote from each other parts of the hulls, and closer to longitudinal axis of symmetry of the bottom 4.

For comfortable sitting, a rotary platform 24 is used (see Figs. 1, 8), made, for example, in the form of a parallelepiped, fixed with the possibility of quick rotation on deck 6 of one of the ski floats 1 or 2 (see Figs. 1, 2, 8).

In this case, the rotary platform 24 can be removable and hollow with a light frame and used, for example, for storage and transportation of the tent (not shown) from durable thin and lightweight material when folded.

If necessary, the ski floats 1 and 2 can be connected to the catamaran using two crossbars 25 (see Fig. 8).

You can connect the ski floats 1, 2 with sticks 16, but then the catamaran is left without a hand mover. Therefore, it is better to use special pipes 26 (see FIG. 8) as crossbars, which in the initial (transport) position can be placed on deck 6 or in the hold of hull 3 and fixed with clips 27.

The assembled catamaran in clean water can be used as a full-fledged vessel, and in the snow - as a drag sled.

In addition, the catamaran can be used as a mobile platform for the construction of a tent (not shown in the drawing) without a bottom (which is especially important for winter fishing or for hunting in wet weather).

For this, on the outside of the hulls 3 of the ski floats 1, 2, bushings (eyelets) 28 are fixed (see Fig. 8) for installing the tent arches 29 (not shown in the drawing).

To ensure compactness during transportation, the proposed device for different types of transportation provides various design options for ski-floats.

In one embodiment, the housing 3 is made integrally, hollow, non-separable. Deck 6 is glued to the sides 5 (see Fig. 12). In this embodiment, the role of a means for additional emergency buoyancy can be performed, for example, by frames (not shown in the drawing) made of a material with a low specific gravity such as foam.

In another embodiment, the deck 6 is removable and mounted on the sides 5 of the hull 3 using screw connections 23 through the seal 30 (see Figure 5), while the frames (not shown) are made inserted.

The cases of ski-floats 1 and 2 can be of different lengths with the possibility of embedding one case into another either entirely (without removable frames), or in parts (as shown in Fig. 9) if there are 3 waterproof partitions 31 in places of the case connectors ( see Fig. 9) and when performing deck 6 detachable of three parts, it becomes possible to compactly package the device.

For example, all parts of deck 6 are placed in compartment A, which is then inserted into compartment B, which, in turn, is inserted into compartment C, which is finally placed in the largest compartment D.

After the parts of the ski floats 1 and 2 are inserted into each other, they, together with deck 6, are placed in a transport case (not shown in the drawing), similar to that for ordinary skis.

In the following embodiment (see Fig. 10, 11, 14, 15) at the level of water line 22 (see Fig. 10), the board 5 of the housing 3 is divided into upper and lower parts, which are interconnected via hinges 33 of flexible and durable material such as PVC fabric.

In the following embodiment (see Figs. 11, 15), the lower parts of the bead 5 are connected to the upper parts and to the bottom 4 through external (in the area of the waterline 22) and internal (at the bottom of 4) hinges 33 made of flexible and durable fabric-type material PVC with the possibility of folding inside the hull 3 of the upper and lower parts of the side 5 relative to each other and the bottom 4.

In the following embodiment (see Fig. 19), it is possible to provide longitudinal folding of the ski float 1 and 2 through transverse flexible hinges 34 connecting the sides of the bead 5 and the bottom 4 at the junction with the insert frames 35, which are closed from below with an additional protective layer 36 plastic with a gap at the joints.

In the next embodiment (see Fig. 12, 13, 14, 15), an inflatable element 37 is attached to the board 5 above the water line 22, which can significantly reduce the rigid part of the housing 3 and increase the stability of the device as a whole during its operation.

In the next embodiment (see Fig. 16), the board 5 is made combined (from different materials): the lower parts 38 of the side 5 are made of hard plastic, and the upper (above the waterline 22) are made of inflatable elements 37. In addition, deck 6 is made made of flexible plastic material such as PVC fabric, the edge 15 of the leg hole is made of flexible and durable material such as PVC fabric stretched over a hoop (not shown in the drawing), and hatches 12 and 13 are fastened, for example, using zippers ( not shown), while the lower parts 38 of the side 5 may yt connected with the bottom 4 through the flexible hinge 33 of a flexible and durable material such as PVC fabric.

In the following embodiment (see FIG. 17), the lower part of the bead 5 is made of hard plastic in the form of a low (slightly raised above the bottom 4) stiffener 39, on which the upper part of the bead 5 is made, made of at least one inflatable element 40, the flattening of which is carried out using bulkheads 41. In this case, deck 6, as in the previous embodiment, is made of PVC fabric.

In the next embodiment (see Fig. 18), the body 3 of the ski-float 1, 2 is mounted and fixed on the pontoon 42 located under the bottom 4, the flattening of the inflatable elements of which is carried out using the bulkheads 43, which can significantly reduce the length of the body 3 of the ski-float 1, 2 and reduce the overall dimensions of the device as a whole.

Immediately after arriving at a place of rest, fishing, hunting, or at a place of emergency after removing parts of the device from the transport case (not shown in the drawing) and simple assembly within 5 ... 20 minutes, the device is ready for immediate operation.

If necessary, the damaged device can be easily repaired by the user himself with improvised or regular (from the traditional for water-tourists remnabor) means.

The device can easily be manufactured both in a single, in serial, and in mass production.

Using the proposed utility model allows you to:
