Boat-catamaran collapsible refers to small floating vessels and is designed for walking and Hiking along the rivers, lakes and coastal zones of the seas with wave height up to 1 m.
Known floating craft catamaran type described in the patent for useful model №99763 with priority from 01.07.2010, publ. 27.11.2010 G. containing longitudinal spaced from each other, at least two of the main inflatable float, connected by a load-bearing structure in the form of a single rigid housing to accommodate the crew, cargo and propulsion, and an additional float of smaller diameter, which form glycerous surface, with the main floats can be made U-shaped in plan, and additional floats - inflatable or rigid.
Closest to the claimed invention by its technical essence is a collapsible catamaran, described in the patent for the invention №2032584 with priority from 25.09.1992, publ. 10.04.1995 g that contains two float and collapsible frame, and connecting them comprising four longitudinal beams, mounted in pairs on top of floats along and United with them by means of the pockets and/or zippers, and placed in pairs of transverse beams connected at their ends with exterior in relation to a diametral plane of the catamaran longitudinal beam�and, moreover, the connection nodes of these cross beams from the inner towards the center plane of the catamaran longitudinal beams interconnected coupling diagonal ties with lanyards.
However, this design has a very low resistance and strength due to the limitations of cylinders in torsion, and the lack of interior does not allow to protect passengers and cargo from all external influences, and also allows you to use the motor for movement.
The present invention aims to obtain the following technical result: the creation of a simple design of a collapsible boat of the catamaran with the possibility of its compact packaging for easy transport and storage, reduced time for Assembly and disassembly of the catamaran, as well as improving the strength and reliability of the frame of the catamaran, with high maneuverability and stability on the water, with the motor for movement, with minimal dive allows you to move in shallow waters, with the protection of passengers and cargo from all external influences.
The problem is solved due to the fact that the device contains two floats, collapsible frame, integral connecting elements, the connecting fasteners, and the floats are supplied with rings, shell rings, stabilizer transversely� sustainability the nasal bump stop, upper and lower support arms, and a collapsible frame cabin, consists of vertical posts, longitudinal and transverse rails, fitted sleeves and corner elements, consisting of four angle brackets, left and right curly corners, sides and interior angles. Boat-catamaran collapsible further comprises a transom, provided with a bottom, a transom Board and fastening the upper and lower rails between which the stop is located. Boat-catamaran collapsible represents the individual modules that allows compact packaging for easy transport and storage. The individual modules with the bond between them form a rigid and sturdy construction. Boat-catamaran collapsible contains two floats representing the inflatable cylinders, provided with eyebolts, which, in turn, is provided with a rim flange with slots and trays shaped channel, which is installed collapsible frame cabin. In the bow of the catamaran is the stabilizer bar, which is a rod (strut) on the ends of which are brackets for fixing to the nasal rings. The stabilizer bar provides synchronous movement of floats on the wave. The stabilizer of cross-fing� is attached to the nasal bump, helps protect interior from splashes. Upper control arms, performing the role of lateral lugs, connected to the rectangular brackets in each top corner of the collapsible frame of the cabin and each outer ring of the float using the pendulum pin. Lower arms are connected with the help of the idler pins with U-shaped brackets located on the bottom cross rails, collapsible frame of the cabin and inner rings of floats. When inflating an inflatable balloon floats up to the total pressure of the vectors of the forces are in compression to the design center and create a single rigid system stops. Thus, creating pressure in tubing, clamped each pin that prevents it from spontaneously move in the attachment. This design creates a system of lateral lugs (handles), allowing to concentrate the force vectors not on the collapse of the structure, and compression to the center of the structure, which eliminates the twisting of the inflatable balloons, and also avoids the precipitation of a collapsible frame of the cabin down to the water surface. This setting levers eliminates the creation of voltage in any of the compounds dismountable boat catamaran that can provide reliability and durability. Prefabricated frame interior with�worth of uprights, longitudinal and transverse rails, fitted sleeves and corner elements. In the longitudinal rails have slots for connection with a transverse rails and to install the uprights of the frame, and transverse rails, projections, and all these elements are paired with each other, which allows for quick Assembly and disassembly of the frame by means of a connecting corner elements without bolts, washers and nuts. Angular elements are composed of square brackets, left and right curly corners, sides and interior angles. Collapsible frame cabin further comprises the bottom of the passenger compartment and transom remote. Transom in turn contains the bottom of the transom, the transom Board and fastening the upper and lower rails, between which is a stop that does not allow deflection of the transom and also transfers the weight of the motor on the stern of the boat, which allows for high maneuverability and stability on the water. Small weight about 50 kg, and with a minimal dip (low rainfall 170 mm) allows the boat-a catamaran to move in shallow waters. Boat-catamaran collapsible additionally equipped with a rowing strips positioned between the nasal and middle upper arms. Rowing rail in turn is equipped with oarlocks, which are rigidly fixed on it. When driving the boat under the motor oars from UCLA�yaytsa on the brackets, located on the aft upper arm. Rowing Reiki are additional stiffener acting in the longitudinal direction.
