Description

 The invention relates to shipbuilding, and in particular to quick-assembled folding boats intended for coastal navigation in calm waters, tourism, hunting, fishing and other purposes.

 Known extremities of folding boats made of elastic sheet material connected by flexible sealed elements located at the junction of parts of the hull, stacked in a package, and containing power hard links. Extremities are known that are close in shape to flat-bottomed without pronounced stem. Boats with such extremities fold compactly, but have low seaworthiness and limited habitability. The bow ends with a stem formed by plates with protrusions and troughs pulled together by a cable and sealed with an inflatable elastic container (N 984920, USSR) are used only for small boats due to the impossibility of folding in a compact package and due to significant deformation of the skin sheets.

 The bow tip of a folding boat is also known, made in the form of plates of elastic sheet material, interconnected by flexible sealed elements, folding into a bag and containing a transverse rigid connection - a jar.

 Due to the flat-bottomed contours of the assembled bow end, the boat has low seaworthiness, has significant resistance to movement, which leads to increased specific fuel consumption and movement at low speed. In addition, due to the steep rise of the bottom, the bow has limited habitability.

 The purpose of the invention is to improve the performance of a folding boat by creating a tip, folding in a compact package and having good habitability and increased seaworthiness.

 The goal is achieved through the use of elastic sheet elements of both triangular and quadrangular shape, interconnected by flexible sealed joints.

 Compared with the prototype, the claimed invention has the following distinctive features: the presence of four triangular and four quadrangular elastic sheet elements mating along rectilinear edges, and the mating angles of the bottom triangular and quadrangular elements are equal, which allows us to conclude that the criterion of "novelty". It is known from the technology to use triangular and quadrangular elastic sheet elements conjugated with each other using flexible hinges. The presence in the claimed invention symmetrical with respect to the diametrical plane of four triangular and four quadrangular elastic sheet elements, mating along rectilinear edges so that four vertices of triangular elements are connected at one point, the opposite sides of these vertices are attached to the bow (stern) edges of the corresponding quadrangular elements, and the mating angles α (figure 1) of the bottom triangular and quadrangular elements are equal, allows you to get nautical contours of the tip, izhennoe driving resistance and improved habitability with minimum dimensions of the folded package.

 In FIG. 1 is a scan of the sheathing of the tip; in FIG. 2 - assembled tip, side view; in FIG. 3 - projection of the housing. in FIG. 4 - section AA in FIG. 2; in FIG. 5 is a section BB in FIG. 2; in FIG. 6 - initial state of the tip of the boat; in FIG. 7 is a diagram for folding the stem; in FIG. 8 - the tip of the boat, folded into a flat figure; in FIG. 9 - tip in the folded state.

 Elastic leaf elements of a triangular shape: 1, 2 starboard and 3 and 4 of the left side and elements of a quadrangular shape: 5, 6 of the right and 7 and 8 of the left side are connected by flexible hinges 9. For successful folding and receiving a compact package, the angles α and β must be are equal in pairs. The starboard element 1 is connected via a flexible hinge to the starboard element 3 on the edge A. A stem line is formed. In a similar manner, elements 1, 2 (3 and 4) are connected at the edges B (C) and elements 5, 6 (7 and 8) along the edges G (D).

 The assembled tip and the projection of the body are depicted in (Fig.2 and 3). Dashed lines show the directions in which folding takes place. In order to achieve the necessary rigidity of the structure and to obtain seaworthy contours of the sheet elements due to the installed frames 9 and 10, the beam 11, cans 12, 13 and payola 14, small deaths are made on conical surfaces within the elastic region of the material.

 Folding the tip is as follows.

 From the initial state (Fig.6), the stem is laid on the line of the keel in the direction of the arrow (Fig. 7). In this case, all sheet elements that had an elastic die are straightened, the sides "automatically" lie on the bottom, a flat figure is formed, which is folded in the diametrical plane (along the arrows in Fig. 8). The result is a compact package, the dimensions of which do not exceed the dimensions of the elastic sheet 6 (figure 1).

 In the case of a particular embodiment, elements of elastic sheet material, for example duralumin, are interconnected via flexible hinges - strips of rubberized fabric with rivets. Collapsible light alloy frames 9 and 10 (Fig. 2), consisting of straight sections, are attached to the casing using wing screws screwed into nuts secured to elastic sheets (not shown). The upper branches of the frames are connected to the fender beam also with the help of wing screws. Banks 12, 13 and payol 14 are the forming elements of the tip. Payol 14 and the bow (stern) jar at the installation sites are fixed relative to the sheathing sheets with pins, pressed one side into the payol 14 (jar) and installed by the other side into the slots on the sheathing sheets (not shown). This method of installing the floor makes it a supporting element, participating in the general bend of the extremity and playing the role of a keel. The rod spacer 15 is a transverse connection that closes the contour: the fender 11 - the frame 9 - the bow (stern) can 12 - payol 14, which increases the rigidity of the structure.

 The assembly of the tip is carried out in the following order: the package (Fig. 9) is deployed relative to the center line along the long side (Fig. 8), after which the stem is raised (in the direction opposite to the arrows in Fig. 7) until it is fully deployed (Fig. 9). 6). After that, the frames 9, 10 (Fig. 2) of the fender bar 11, the bolt spacer 15, payola 14, cans 12 and 13 are installed. Disassembly is carried out in the reverse order: cans 12 and 13 (Fig. 2) are removed, payol 14, pin the spacer 15, the fender bar 11, the frames 9 and 12 are removed, the casing is folded into a compact package in accordance with Fig.9.
