The invention relates to a flotation device - boats, equipped with fins and boats, equipped with means to enable their movement on land.

Famous boat that is capable of transporting it by land (EN 2182097 C1, 10.05.2002, VS 13/00), which includes a housing containing the transom frame, which is attached to two brackets, which are associated with the ability to rotate about horizontal axes stand with wheels for transportation of boats by land, a rack provided with a cylindrical lugs, and brackets at the top and bottom parts are made of the saddle, which posted bolts for fixing the racks in the extreme positions, wherein the racks are made longitudinal slots and bolts placed with the possibility of linear movement in the longitudinal slots of the uprights and is spring-loaded. The disadvantage of this technical solution is the complexity and inconvenience of the transfer wheel from the provisions for the transportation of boats by land in position for movement on water. In addition, it should be noted that in this construction of the boat is not provided design features aimed at improving stability of the boat, as well as providing interaction of the wheels with the terrain land over which conveys�Iruka boats.

In the prior art constructive solution used in walking vehicles, particularly in amphibians, allowing you to interact with the surface over which the movement is carried out, and to overcome when moving minor irregularities of this surface, which is a wheeled unit, consisting of three wheels attached uniformly and symmetrically about its axis of rotation (JP 11-217001 A1, 10.08.1999, WV 19/00, B62D 57/02). In this technical solution does not solve the problem of improving the swimming characteristics of the boat, in particular stability when moving amphibians on water.

The closest analog of the invention is the boat disclosed in the patent US 4920909 A1, 01.05.1990, VS 13/00, comprising a housing and two keel placed in the recesses of the bottom of the housing, protruding relative to the bottom of the housing, vertically oriented along the direction of movement of the boat and are in the form of wheels which are mounted for rotation. The technical result of the invention is to facilitate the movement of the boat by land, providing reduced resistance to movement of a boat on the water and increase the speed of movement of the boat in the water, providing additional stability and hydrodynamic balance of the boat when moving through the water, reducing the risk of damage to the hull bottom on �elcoodge in a collision with the bottom of the reservoir. In this design of the boat is not provided design features aimed at ensuring interaction of the wheels with complex terrain land over which the transportation of the boat. Thus the disadvantage of this technical solution is the impossibility of overcoming the minor irregularities on the bottom of the reservoir and on land.

The technical result of the invention:

- facilitating the movement of the boat on land (including land with difficult terrain);

- ensuring increasing the speed of movement of the boat through the water (especially in shallow water);

- ensuring high maneuverability of the boat on the rough bottom of the reservoir with muscular force of one or two people in a constructive and technological simplicity of the device;

- reducing the risk of damage to the bottom of the boat in shallow water in a collision with the bottom of the reservoir;

- giving stability and hydrodynamic balance of the boat when moving through the water.

The technical result is achieved by the following design features run the boat.

The boat includes a housing, three keel protruding relative to the bottom of the housing and oriented vertically along the longitudinal axis of the boat. Two of these keels are placed in the stern of the boat is symmetrical relative to its longitudinal axis, Treti - in the middle part of the boat on its longitudinal axis. Each of the fins is made in the form of a wheel unit mounted on the outside of the bottom of the housing for rotation along the longitudinal axis of the boat, containing three wheels, mounted evenly and symmetrically relative to the axis of rotation of the wheel unit rotatably along the longitudinal axis of the boat and made of the same size and with different weights. While two of the three wheels have a maximum and minimum weight, and the third wheel has a medium weight with respect to the two mentioned.

In the particular case of the invention, the boat can be equipped with two MaterialName wheels mounted on the outer side of the bottom of the body on its longitudinal axis in the aft and front side, respectively, for rotation along the longitudinal axis of the boat, and a closed rope, stretched in girth between MaterialName wheels with a single entanglement mentioned wheel block, located in the middle part of the boat, from the bottom of the casing, with the wheels mentioned wheel block, located in the middle part of the boat is provided with two grooves for the wire.

Running the boat with three keels, two of which are placed in the stern of the boat is symmetrical relative to its longitudinal axis, and a third in the middle part of the boat at its �rodolniy axis, represents the best option for the simplicity, ease of design and its functionality. Keeley made in the form of so-called walking wheel blocks that interact with the bottom of the reservoir or the land surface. Use wheel blocks with three rotating wheels allows different weights to facilitate the movement of the boat by land with muscular force of one or two people, and also to provide a high permeability of the boat on the rough bottom of the reservoir, to increase the speed of the boat in shallow water and to give additional stability and to provide a hydrodynamic balance of the boat when moving through the water.

The weight of the wheels in the wheel block ensures lowering the centre of gravity of the boat, which in turn provides increased its stability, and also provides a contact of two wheels, one wheel block with the roughness of the bottom of the reservoir or sushi, which increases the permeability of the boat.

To enhance the effect of reducing the risk of damage to the bottom of the boat in a collision with an obstacle on the terrain (as when moving in the water and on land) the boat can be equipped with two MaterialName wheels and a closed wire. In this particular embodiment of the invention notarialne wheels are mounted outside of the housing base on his PR�longitudinally axis respectively in the stern and bow parts for rotation along the longitudinal axis of the boat. Vicious rope stretched covering notarialnych wheels and wheel unit, located in the middle part of the boat. For a safe design of the cable is located in the locating grooves notarialnych wheels and wheels mentioned wheel block. To preserve the possibility of rotation mentioned wheel block the cable from the bottom of the hull wrapped around the wheel of the unit from top to bottom with loop (cross or overlap the cable is from the bottom of the hull).

When the boat collision with an obstacle in the water during its movement the rope in the bow will ensure the braking stroke of the boat, which will allow more smoothly to overcome the obstacle, and the rope at the stern of the boat will reduce the probability of impact the aft hull bottom of the obstacle.

The invention is illustrated by the following drawings, which shows:

Fig.1 - view of the boat from the bottom side of the bottom of the hull.

Fig.2 is a side view of the keel, made in the form of a wheel unit;

Fig.3 - cross section A-A of the keel, made in the form of a wheel unit;

Fig.4 - view of the boat from the bottom side of the bottom of the hull with optional equipment - MaterialName wheels and rope;

Fig.5 is a side view of the keel, made in the form of a wheel block, with the taut rope around him;

Fig.6 is a sectional view of the boat along its longitudinal axis in the interaction of the cable with pre�atstat under the floor in the position - the obstacle in the bow of the boat);

Fig.7 is a sectional view of the boat along its longitudinal axis in the interaction of the cable with a barrier under the floor in the position of the obstacle in the aft of the boat).

In the figures the positions marked with the following elements:

1 - the bottom of the hull;

2 - the keel in the form of a wheel block, located in the aft of the boat;

3 - the keel in the form of a wheel block, located in the middle part of the boat on its longitudinal axis;

4 - wheel wheel block having the largest weight;

5 - wheel wheel block having the least weight;

6 - wheel wheel block having an average weight relative to the weight of the other two wheels;

7 - notarialne wheel, located in the aft of the boat;

8 - notarialne wheel, located in the bow of the boat;

9 - rope;

10 is an obstacle (in the water at the bottom of the pond or on the land surface).

Boat 1 is equipped with two keels in her aft in the form of a wheel block 2 and one keel in the middle part in the form of the wheel unit 3. These Keeley prevent the landing of the boat aground. The boat when moving on land or shallow water and in contact with an obstacle 10 (including vertical) elevation greater the diameter of the wheels 4, 5, 6 wheel block, overcomes the obstacle by turning the wheel block and wheels. The weight of the wheel unit as keel sensor�em lowering the centre of gravity of the boat, provides increased resiliency and provides interaction with the terrain of the seabed or land by contact with them immediately with two wheels which have the greatest weight (wheel 4) and average weight (wheel 6) that increases the permeability of the boat.

The boat with the keel of this design is expected to be used primarily in flooded areas in the evacuation and rescue operations, for tourism, especially in shallow waters. Due to the high permeability of the irregularities of the bottom of the reservoir, the boat can be refloated the muscular force of one, maximum of two people and a boat without retooling can move on land.

To enhance the effect of reducing the risk of damage to the bottom of the boat 1 in a collision with an invisible barrier on the bottom of the reservoir 10, the boat can be equipped with materialsim wheel 8 at the bow and materialsim wheel 7 at the rear, connected by a closed cable 9 (for example, steel with polymer coating, etc.) with the wheel unit 3, located in the middle part of the boat. The cable 9 dampens shock when the boat collision with an obstacle 10, slowing its movement. In addition, after overcoming the obstacles boat rope 9 prevents a possible shot aft hull bottom an obstacle due to the cable tension between MaterialName wheel�and 7 and 8 and the keel in the form of the wheel unit 3, located in the middle part. Also the cable 9 prevents damage to the blades of outboard motor boats on the obstacle after overcoming the boat.

Thus, the proposed design of the boat has the following advantages:

- the boat with the keel in the form of walking wheel blocks can move on land with difficult terrain and can also be easily refloated;

- Kili in the form of walking wheel blocks provide increased speed of travel of the boat in shallow water, reduce the risk of damage to the bottom of the boat in shallow water when confronted with obstacles located on the bottom of the reservoir, as well as provide additional directional stability and hydrodynamic balancing the boat when moving through water;

- equipping boats with additional equipment - MaterialName wheels and rope, reduces the risk of damage to the bottom of the boat and outboard motor.
