Description

The collapsible catamaran refers to small-sized floating vessels and is intended for walking and hiking along rivers, lakes and coastal zones of the seas at a wave height of up to 1 m.

A catamaran type floating device is known, described in the patent for utility model No. 99763 with priority of 07/01/2010, publ. 11/27/2010, containing longitudinally spaced apart from each other, at least two main inflatable floats, interconnected by a power frame in the form of a single rigid body to accommodate the crew, cargo and propulsion, and an additional float of a smaller diameter, which form a planing surface moreover, the main floats can be made U-shaped in plan, and additional floats - inflatable or rigid.

The closest to the claimed invention in its technical essence is a collapsible catamaran described in the patent for invention No. 2032584 with priority from 09/25/1992, publ. 04/10/1995, containing two floats and a collapsible frame connecting them and including four longitudinal beams, pairwise mounted on top along the floats and connected to them by pockets and / or fasteners, as well as pairwise placed transverse beams connected at their ends with longitudinal beams external to the diametric plane of the catamaran, and the nodes of the connections of these transverse beams with the longitudinal beams internal to the diametric plane of the catamaran are connected by coupling gonal ties with turnbuckles.

But this design has extremely low stability and strength due to the absence of restrictions on torsion cylinders, and the lack of a passenger compartment does not protect passengers and cargo from all external influences, and also does not allow the motor to be used for movement.

The present invention is aimed at obtaining the following technical result: the creation of a simple design collapsible catamaran boat with the possibility of compact packaging for ease of transportation and storage, reducing the time for assembly and disassembly of the catamaran, as well as increasing the strength and reliability of the frame of the catamaran, possessing high maneuverability and stability on the water, using a motor for movement, with minimal immersion allowing you to move in shallow water, with passenger protection cargo from all external influences.

The problem is solved due to the fact that the device contains two floats, collapsible frame, composite connecting elements, connecting fasteners, and the floats are equipped with eyebolts, shells, anti-roll bar, nose chipper, lower and upper supporting arms, and collapsible frame cabin, consists of vertical struts, longitudinal and transverse rails, equipped with bushings and corner elements consisting of quadrangular brackets, left and right curly corners, side and inside corners. The collapsible catamaran boat further comprises a transom equipped with a bottom, a transom board and mounting upper and lower rails, between which an emphasis is located. The collapsible catamaran boat is a separate module, which allows compact packaging for easy transportation and storage. The individual modules, when bonded to each other, form a rigid and durable structure. A collapsible catamaran boat contains two floats, which are inflatable balloons equipped with rings, which, in turn, are equipped with shells with slots and channel shaped trays on which a collapsible cabin frame is mounted. In the bow of the catamaran there is a stabilizer bar, which is a rod (spacer), at the ends of which there are brackets for attachment to the bow rings. The anti-roll bar provides synchronized movement of the floats on the wave. A nose bump is mounted on the anti-roll bar to protect the interior from splashes. The upper levers, acting as side stops, are connected to the quadrangular brackets in each upper corner of the collapsible cabin frame and each outer ring of the float using a pendulum cotter pin. The lower levers are also connected using pendulum cotter pins with U-shaped brackets located on the lower transverse rails of the collapsible frame of the passenger compartment and the inner rings of the floats. When inflatable balloons of floats are inflated to full pressure, the force vectors work to compress to the center of the structure and create a single rigid system of stops. Thus, creating pressure in the inflatable balloons, each cotter pin is clamped, which does not allow it to spontaneously move in the attachment points. This design creates a system of lateral stops (levers), which allow concentrating force vectors not on the collapse of the structure, but on compression to the center of the structure, which eliminates the inversion of inflatable balloons, and also avoids the collapsible collapsible carcass of the cabin down to the water surface. This installation of levers eliminates the creation of tension in any joints collapsible design of the catamaran boat, which allows to ensure the reliability and durability of the structure. Collapsible interior frame consists of vertical struts, longitudinal and transverse rails, equipped with bushings and corner elements. In the longitudinal rails there are slots for connecting to the transverse rails and for installing vertical frame racks, and in the transverse rails there are protrusions, and all these elements are interconnected, which allows for quick assembly and disassembly of the frame using connecting corner elements without bolts, washers and nuts. Corner elements consist of quadrangular brackets, left and right curly corners, side and inner corners. The collapsible cabin frame further comprises a passenger compartment bottom and a remote transom. The transom, in turn, contains the bottom of the transom, the transom board and the mounting upper and lower rails, between which there is an emphasis that prevents the transom from bending, and also transfers the weight of the motor to the stern of the boat, which allows for high maneuverability and stability on water. The light weight of the structure is about 50 kg, and with minimal immersion (low draft 170 mm) allows the catamaran boat to move in shallow water. The collapsible catamaran is additionally equipped with paddle rails located between the bow and middle upper arms. The paddle rail, in turn, is equipped with oarlocks that are rigidly fixed to it. When the boat moves under the motor, the oars are placed on the brackets located on the aft upper arms. Rails are an additional stiffener acting in the longitudinal direction.

Figure 3 shows side corner 14, inner corner 15, quadrangular bracket 16, curly right head 17 and figured left corner 18, vertical strut 19, sleeve 13, transverse rails 9, longitudinal rails 10. Figure 4 shows floats 1, transverse rails 9, vertical racks 19, upper levers 20, lower levers 21, trays 22.

The assembly of the catamaran boat is carried out as follows: in the lateral slots 11 of the longitudinal rails 10, the protrusions 30 of the transverse rails 9 are inserted. Vertical struts 19 are installed in the internal slots 12 of the longitudinal rails 10. At each corner of the collapsible frame of the cabin 2, due to the corner connecting elements, consisting of lateral 14 and inner 15 corners, a quadrangular bracket 16, curly right 17 and curly left corner 18, longitudinal 10, transverse rails 9 and vertical posts 19 are connected and by shifting the bushings 13 to the center of each the corner of the cabin 2. The floats 1 containing the eyebolts 3 are equipped with shells 4 and channels 22 having a channel shape on which the collapsible frame of the cabin 2 is mounted. The upper arms 20 are connected to the quadrangular brackets 16 in each upper corner of the frame of the cabin 2 using the pendulum cotter pin (not shown in the figure). The lower levers 21 are also connected using pendulum cotter pins with U-shaped brackets (not shown in the figure) located on the lower transverse rails 9 of the passenger compartment carcass 2. When the floats 1 are pumped to full pressure, the force vectors work to compress to the center of the structure and create a single rigid emphasis system. After installing the levers 20 and 21, the bottom of the cabin 8 is installed, then the anti-roll bar 28 of the floats 1 is installed, made in the form of a rod (strut) with a length of 1500 mm., With the nose bump fixed to it 7. The transom 5 assembly is installed after installing the bottom of the frame 8 in the aft compartment 2. Transom 5 contains the bottom of the transom 31, the transom 6 and the mounting upper rails 25 and lower rails 23, between which there is an emphasis 24, which prevents the deflection of the transom, and also transfers the weight of the motor to the stern of the boat. The bottom 8 consists of four insert elements, two of which are in the aft and two in the bow of the passenger compartment 2. The collapsible catamaran is additionally equipped with paddle racks 26 located between the bow and middle upper arms 20. The paddle 26 is in turn equipped with oars which are rigidly fixed to it. When the boat moves under the motor, the oars are placed on the brackets 29 located on the aft upper arms 20. The paddles 26 are an additional stiffening rib operating in the longitudinal direction. The collapsible catamaran boat can additionally be equipped with soft chairs specially designed for this design, as well as equipped with a windshield, a folding tent, a folding cabin (pvc), for the convenience of passengers and the safety of cargo and personal belongings. All of the equipment listed is manufactured and tested on a prototype in the Volga River.
