The invention relates to a collapsible floating structures with a small draught and can be used for independent movement of the vehicle through the water.

The movement of the vehicle on water, including shallow waters, possibly with the help of the floating structure with a small draught, type of pontoon catamaran raft. Known floating structures that are closest to the claimed device, select floating villas (PD), a shallow-draught of the pontoon catamaran base type, in which the movement of water by using hanging or stationary outboard motors, or by towing. For transportation by land floating villas converted into a truck trailer. Description houseboat both domestic and foreign, are given in the journals of "Boats and yachts". See, for example, Eaating "Court-Dachi, No. 1, 1963, pp.92-95, 4 Il; brief description AP American company "Cait, No. 1, 1977, p.19-20, 3 Il; PD "Alenka", Association "Rhythm", No. 1,1972, p.10, and No. 1,1977, p.12-14, 1 ill.; high-speed PD - catamaran, No. 6, 1977, p.45-46, 2 Il.

The closest analogue of the claimed invention can be considered as a high-speed PD - Catamaran, see log for "Boats and yachts". No. 6, 1977, p.45-46, 2 ill., which was adopted as a prototype. The prototype has two float welded from 1.5 mm steel. The size of each float L=7,5 is, In_to=0.5 m, draught T=0,12 m Movement through the water by using outboard motor "Moscow is 12.5". Full weight - 800 kg Prototype does not allow for independent movement of the vehicle through the water.

The aim of the invention is the creation of a collapsible pontoon catamaran with a shallow draft to be converted in the trailer when driving on land, which in the assembled condition allows the car on their own, using their own weight, due to the momentum of the body to push itself along with the pontoon from the shore into the water and move water through your engine, driving traffic from the cab, as well as when driving on dry land.

The inventive collapsible pontoon catamaran for independent movement on the water front-wheel drive vehicle is transported when driving on land in the form of a trailer. He has collected from sections of flat floats. They are connected beams and. installed on floats the wheel wells and folding chocks under the bumpers for entry. exit, placing and fixing the car on the pontoon during the voyage. The distinctive part is the addition of rotating propellers driven by the front wheels, which are mounted in the swivel cradle rigidly connected with the drive of a propeller consisting of a rotating wheel drum. which, through the gear associated with rowing VI is volume.

Figure 1 presents a General view drawing of the pontoon for front-wheel drive passenger car.

The pontoon has two flat float. Each float consists of four sections 1. The floats are connected to the catamaran three beams 2. On floats installed wheel housing 3 corresponding to the width of the wheels. On floats installed also stops 4 under front and rear bumpers of the vehicle. The wheels of the trailer posted on the stops and serve as a buffer when vtalkivaniya pontoon in the water. In the wheel recesses 3 of the pontoon designed for front-wheel drive car, the location of the front wheels made the cut, which is in the form of a single construction unit installed lodgements wheels, together with the drums, gears and propellers. Lodgement is rectangular glass 5. In the center of the bottom of the glass placed the shaft 6 for rotation around a vertical axis. Section of the float, which placed the cradle has a slot to insert the shaft. The upper part of the beaker equipped with passive rollers 7. Adhering to the wheel, they fix its position, allowing the wheel to freely rotate. In the middle part of the glass of the bearings installed drum 8. The axis of the drum with the outer side out of the Cup in the form of a shaft. This shaft is connected with the gearbox, which has two conical gear pair 9. The output shaft 10 of the gear is g is BNYM screw. It fixed propeller, closed the nozzle 11. The gearbox is installed on an external side wall of the Cup and can have one of two States: working, in which the screw is lowered into the water, and duty, in which the screw is lifted out of the water. The drum has a stopper that is used at the entrance of the car on the pontoon and exit, to avoid stalling. Constructive node - lodgement, drum, gearbox, propeller screw is inserted into the slot of the shaft section 6 of the float Assembly. Section floats that have the containers have openings through which the propeller can be raised out of the water or lowered into the water.

The device operates as follows. A vehicle with a towed trailer, 3, drove up to the waterfront. From the parts contained in the trailer, going to the pontoon. The Assembly is carried out so that the bow of the pontoon would be in the water. Before entering a vehicle, the pontoon must be shown in its original position. Namely, raised and fixed the emphasis under the front bumper, the emphasis under the rear bumper is omitted, the screws are raised out of the water, the reel mounted on the stopper. The car from the shore wheeled niches entering the pontoon. Upon contact of the front bumper with a focus, at the expense of momentum of a body is the intersection of the pontoon with the car in the water. If necessary, this operation can be repeated. After the Pont is n with the vehicle is afloat, you need to raise and secure the emphasis under the rear bumper, remove the stopper from the reel and drop into the water screws. Then you can sit in the car and continue along the water, as well as by land. The front wheels transmit the rotation to the drums, and from them, through gearboxes, propellers. The direction of movement is determined by the position of the steering wheel of the vehicle, the front wheels sets the direction of the axes of the propellers. Berthing pontoon to the shore as possible nose and stern. Exit the car on the beach, disassembly of the pontoon and the layout of the car trailer in reverse order.

The inventive collapsible pontoon catamaran for independent movement on water, rear-wheel drive car is transported when driving on land in the form of a trailer. He has collected from sections of flat floats. They are connected beams and mounted on floats the wheel wells and folding chocks under the bumpers for entry. exit, placing and fixing the car on the pontoon during the voyage. The distinctive part is the addition of a paddle wheel driven by the front wheels and propellers driven by the rear wheels of the vehicle. The front wheels are swivel-cradle rigidly related blade rudders. The rear wheels are installed in h is movable cradle drive propellers, consisting of a rotating wheel drum, through which the gearbox is connected with the propeller screw.

Figure 2 presents a General view drawing of the pontoon for rear-wheel drive passenger car.

The cradle for the front and rear wheels 2 are indicated by numbers 1 and 2. Each lodgement installed in the cutout of the wheel housing. Cradles the front wheels are pivoted around a vertical axis, as in the pontoon for front-wheel drive car. Blade rudders, indicated by figure 3, mounted on the outside wall of the glasses of these lodgements. The mount provides two rudders their position is one in which the Elevator is lowered into the water, and the second, in which the Elevator is raised out of the water. Section floats that have these cradles have a cutout, through which the handlebars can be raised or lowered into the water. Cradles the rear wheels with the drive and propeller screw is made the same way as in the pontoon for front-wheel drive car except for the possibility of rotation around the vertical axis. Section floats were installed on these nodes have a cutout, through which the screws can be raised or lowered into the water.

In the operation of the pontoon is added to the operation of raising-lowering steering. The rest is the same as the front of the car.

Figure 3 presents the parsed pontoon arranged in a V is e trailer for towing by a vehicle while riding on land.

Declared pontoon catamaran allows serial car without any alteration to move independently through the water. The management of the movement occurs from the cab, as well as when driving on dry land. For launching the car itself on the pontoon, precipitated into water. After mooring to the shore car drives off the pontoon on the land. When driving on land pontoon is transported as a trailer. In the Parking lot of the pontoon can be deployed in the form of a tent house. To overcome the difficult sections of the pontoon can be used as pads under the wheels.
