RU140473U1 - INFLATABLE BOAT WITH BOTTOM IN THE FORM "WING OF SEAGONS" - Google Patents

Abstract

The inflatable boat contains a board in the form of an inflatable U-shaped balloon, a transom installed in the stern of the boat, an inflatable bottom, consisting of an upper flat bottom and a lower curved bottom, attached to the lower part of the side, and the end part. The upper and lower bottoms are made of elastic material and are interconnected by forming partitions, and the lower bottom in cross section and the lower edge of the end part have the shape of a “gull wing”. The utility model provides improved hydrodynamic characteristics, improved stability on the course and exit to planing.

Description

The utility model relates to shipbuilding, in particular to motor inflatable boats.

Known inflatable boats with a flat bottom. Boats with such a bottom experience strong impacts on the surface of the water, even with slight excitement.

The closest analogue to the proposed utility model is the solution (motor inflatable boat "Frigate 370 Pro", http://web.archive.org/web/20130326092138/http://velhod.ru/catalog/boats/fregat-boats_370pro.html , March 26, 2013), in which an inflatable boat is disclosed containing a board in the form of an inflatable U-shaped balloon, a transom installed in the stern of the boat, an inflatable bottom consisting of an upper flat bottom and a lower curved bottom attached to the lower part of the side, an inflatable keel , rigid collapsible payol, while the lower edge of the transom is made in the form of a “gull wing”.

The disadvantages of the boat disclosed in the closest analogue is:

- heavy boat weight due to wooden floorboards;

- insufficiently high hydrodynamic characteristics due to the unstable shape of the keel channels, as well as the deflection of the bottom with a large load due to the presence of voids between the floorboards and the elastic bottom;

- non-compact packaging of the boat due to the presence of hard flooring and fasteners.

The proposed utility model is aimed at eliminating the above disadvantages.

The technical result of the proposed utility model is to improve the hydrodynamic characteristics, improve stability on the course and exit to planing and is achieved by the fact that the inflatable boat contains a board in the form of an inflatable U-shaped balloon, a transom installed in the stern of the boat, an inflatable bottom, consisting of an upper flat the bottom and the lower curved bottom attached to the lower part of the side and the end part, the upper and lower bottoms being made of elastic material and interconnected to form a burnout Odds, the lower bottom in cross section and the lower edge of the end part have the shape of a “gull wing”.

The lower bottom consists of two mirror-symmetric concave halves, which are interconnected by a ribbon of PVC fabric.

Outside the lower bottom, at the junction of the halves, a triangular elastic profile is glued along the entire bottom.

On the outer surface of the upper bottom is glued or welded anti-slip coating.

A protective plate of PVC is glued to the outer surface of the bottom.

The bottom is an inflatable bottom of low pressure.

The forming partitions are connected to the inner surfaces of the upper and lower bottoms by means of T-shaped profiles made of PVC or corner PVC strips glued or welded along the bottoms.

The transom is installed in the stern of the boat with the help of shaped elements fixed on the inside of the side.

The end part of the bottom is attached to the lower part of the transom and the lower bottom.

On the perimeter of the bottoms, from the inside, glued corner reinforcing tapes made of PVC fabric.

Protective strips of PVC are glued to the underside of the side.

The proposed utility model is illustrated by drawings:

FIG. 1 - front view of the boat (D - bottom profile in the bow, F - bottom profile in the stern, Ε - bottom profile in the midship);

FIG. 2 - side view of the boat;

FIG. 3 is a general schematic view of a boat;

FIG. 4 - boat feed;

FIG. 5 is a schematic section of a boat;

FIG. 6 - options for joining the forming partitions to the upper and lower bottoms.

The inflatable boat contains a board (1) in the form of an inflatable U-shaped balloon, a transom (2) for mounting the motor installed in the stern of the boat, an inflatable bottom consisting of an upper flat bottom (3) and a lower curved bottom (4) attached to the lower parts of the bead and end part (5), the upper (3) and lower (4) bottoms made of elastic material (for example, PVC, rubber, etc.) and interconnected by forming partitions (6), the lower bottom ( 4) in the cross section and the lower edge of the end part (5) have the shape of a “gull wing”.

The lower bottom (4) consists of two mirror-symmetric concave halves, which are interconnected by a tape (7) made of PVC fabric. Outside the lower bottom (4), at the junction of the halves, a triangular elastic profile (8) is glued along the entire bottom. An anti-slip coating (9) is glued or welded onto the outer surface of the upper bottom (3). A protective plate (10) made of PVC is glued to the outer surface of the lower bottom (4). The forming partitions (6) can be attached to the inner surfaces of the upper and lower bottoms by means of T-shaped profiles (11) of PVC or corner strips (12) of PVC glued or welded along the bottoms. The transom (2) is installed in the stern of the boat with the help of shaped elements (13) fixed on the inside of the side. The end part (5) of the bottom is attached to the lower part of the transom (2) and the lower bottom (4). Along the perimeter of the bottoms (3, 4), on the inside, corner reinforcing tapes (14) made of PVC fabric are glued. Protective strips (15) made of PVC can be glued to the bottom surface of the side (1).

The manufacture of the boat according to the proposed utility model can be carried out in industrial production using existing equipment, existing technology, serial materials and does not require the use of special equipment and devices.
