Abstract

Using; in folding boats as trailers vehicles. The essence of the invention: a folding boat contains a stern section and a nasal section, provided with a windproof diaphragm, the surface of which is made in a form congruent to the inner surface of the nasal section. The upper hinges and locks, installed in the lower part of the bow section, connect the latter with the lugs of the aft section and with the wind-pressure diaphragm. 2 hp f-ly, 5 ill.

Description

This invention relates to craft and can be used in folding boats transported as vehicle trailers.

A collapsible boat-trailer is known, containing a stern section and a bow section connected to it by means of upper hinges and locks.

Its disadvantages include the inconvenience with the changeover associated with the placement of the sail, which impairs the ride quality.

The purpose of the invention is to improve ride quality, compactness and ensure convertibility when planing.

This goal is achieved by the fact that in a folding boat containing feed and bow sections, interconnected by means of hinges located in the upper parts of these sections and locks, the bow section is provided with a wind-pressure diaphragm with locking clips, the surface of which is shaped according to a congruent internal shape the surface of the nasal section, while the windproof diaphragm is installed with the possibility of rotation around the transverse horizontal axis located in the plane of the section of the boat sections, by means of arnirov and locking it in an upright position by said locking clamps.

In addition, the windspray diaphragm is made of a laminate based on a fabric of glass or synthetic yarns and connecting with eyelets for the indicated hinges, and the locking clips are located in the lower part of its side walls.

Distinctive features of the folding boat are the presence of a wind-pressure diaphragm with locking clips with a surface, a congruent inner surface of the bow section, the ability to rotate the diaphragm around the transverse horizontal axis located in the plane of the boat's connector, using the specified hinges and fixing it in the vertical position by locking locks from ell

raw plastic based on fabric from glass or synthetic yarns and a binder, with eyelets for the indicated hinges, with locking clips in the lower parts of the side walls of the diaphragm.

FIG. 1 shows a foldable trailer boat, isometric, FIG. 2 - sections of attachment of sections and diaphragm; in fig. 3 - foldable boat-trailer in transport position; in fig. 4 - the same, in the unfolded position; in fig. 5 - the same, with a diaphragm and keel.

Foldable trailer boat contains aft and bow sections 1 and 2, single-door diaphragm 3 with surface 4, made in form, congruent inner surface 5 of bow section 2, mounted rotatably around a transverse horizontal axis 6, located in the plane of the connector of 7 sections 1 and 2 of the boat by means of hinges 8 and fixing it in a vertical position by means of locking retainers 9, a lock 10 for fixing the bow section 1 and the aft section 2 in the unfolded position, installed if necessary, A spring engine 12 or a steering 13. The wind-diaphragm 3 is made of laminated plastic based on a fabric of glass or synthetic threads and a binder, with eyelets 14 for hinges 8, locking clips 9 in the lower parts of its side walls 15.

The operation of the folding trailer boat is as follows.

For transport by wheel transport, the boat folds into position (Fig. 3) so that the bow section 2 is narrowed towards the vehicle and is directed in the direction of movement, while due to congruence the wind pressure diaphragm 3 occupies a similar position in the bow section 2 and is fixed by locks 16 with the aft section one,

To move the boat with a sail (Fig. 5), the windap diaphragm 3 is transferred from a horizontal position to a vertical one with rotation around the hinges 8 with its subsequent fixation by means of locking latch 9 so that the wind load acts on it from its single-sided niche and, conversely, from vertical position in the horizontal, depending on the need for speed of movement of the boat.

Thus, the positive effect from the use of the invention is to simplify the manufacture, compactness of the folding boat with a wind-supporting diaphragm, convertibility when planing, improving the ride quality and operational reliability of the boat.
