RU2456197C1 - Higher-rigidity inflatable boat with self-bailing cockpit (versions) - Google Patents

Abstract

FIELD: transport.

SUBSTANCE: invention relates to inflatable boats. Proposed boat has inflatable bottom and side cylinders. Said bottom is made up of cylinder with several internal vertical webs, or said bottom has vertical and one or two horizontal webs. Said webs are watertight. Height of vertical webs exceeds that of static waterline. Total width of horizontal webs is smaller than that of the bottom.

EFFECT: higher rigidity.

Description

The invention relates to inflatable boats for four purposes - for recreational walks, for fishing, for amateur and professional diving and for rescue operations in the stormy sea.

Inflatable boats of various designs are known, see A.S. 608695. Boats with a hard floor are heavy, wear out faster, and it is inconvenient to scoop out water from them. Boats with an inflatable or single-layer bottom are uncomfortable to operate - they create a feeling of unsteadiness underfoot. And those and others when flooding a wave become helpless, in particular - the motor stalls.

To eliminate these drawbacks, two methods are used.

INVENTION 1. The boat has a self-draining cockpit, for which the bottom is made in the form of a cylinder with several internal vertical breathable partitions made of fabric or film, the height of which is greater than the height of the static waterline.

A transom on such a boat is attached to its stern and reinforced with guy wires at the top and a continuous waterproof tape at the bottom. This tape is a hydrodynamic extension of the bottom and creates a significant proportion of the lift when gliding, so it must be well stretched during the manufacture of the boat.

To improve flow stall at the stern during gliding, the lower part of the stern of the cylinder has a redan-shaped overlay.

For free drainage of water from the self-draining cockpit in the stern, the side cylinders are completely or partially absent, and the resulting opening between the cylinders or between the cylinder and the transom is tightened with a net (the net must be attached to the cylinders and / or transom with a quick-detachable fastener, for example carbines.

Passengers are accommodated in a boat while sitting, lying and reclining right at the bottom of the cockpit. However, for the driver it is necessary to have a more reliable and higher landing. Therefore, the boat has a fixed inflatable or rigid seat in the cockpit, to which a back is attached, fixed in the right position by two guy wires. If the boat is motorized, then it is very convenient to use a fuel tank of the appropriate shape, attracted to the tank by variable-length belts.

To meet its purpose, the boat must have a sufficiently large width. In this case, on side waves, the boat, which is essentially a raft with sides, may experience some deformation. And although such a thick cylinder has great rigidity, it is desirable to increase this rigidity.

INVENTION 2. For this, the inflatable bottom of the boat has internal vertical breathable partitions and has one or two horizontal breathable bridges parallel to and adjacent to the upper and / or lower surfaces of the bottom, and the total width of these horizontal bridges is less than the width of the bottom.

The upper and lower surfaces of the bottom have a wavy shape in the inflated position, which allows them to relatively “broaden” due to the smoothing of these waves. And the horizontal breathable lintels inside the container are plane in shape and therefore cannot stretch. Which determines the high rigidity of this design.

Such a bottom seems technologically very complex, but it is not. If you apply firmware on a sewing machine and heat-resistant material for jumpers (cheap burlap, tarpaulin or tarpaulin), then such a bottom is easily glued and welded.

Figure 1 shows the cross section of the boat, where: 1 - the bottom of the cylinder, having seven vertical partitions 2 inside, and one horizontal jumper 3, parallel to the bottom surface of the bottom of the cylinder. Top cylinders 4 are glued at the top.

Figure 2, 3 shows the manufacturing technology of the bottom. First, the vertical partition 2 is sewn to the strip of hydraulic fabric 5. Then, it is also sewn with one seam to the horizontal bridge 3 and to the other strip of hydraulic fabric 5. After that, both strips 5 are glued or welded to the upper and lower surfaces of the bottom cylinder 1. The edges of the horizontal bridge are also attached. to the side parts of the cylinder 1.

It is recommended to stitch all seams first. And then glue or weld all seven vertical partitions one at a time. The connection will be strong and reliable. A technology with two horizontal jumpers is not much more complicated than with one jumper.

Figure 4, 5 shows the equipment of the boat. The transom 6 is glued to the stern and secured from below by tape 7, and from above by guy wires 8. The seat 9 is attached to the bottom (the inflatable can simply be glued), and the back 10 is attached to it, which is fixed in the right position by guy wires 11. Between the roundings of the side cylinders and the net 12 is attached to the transom.

The approximate dimensions of the boat shown are: length 3.1 m, width 2 m. Bottom thickness 30-36 cm, diameter of side cylinders 20-25 cm.

During rescue operations, it is convenient to lift people out of the water through a relatively low side. To lift overweight, exhausted people, one of the rear nets should be unfastened and a person drawn through the stern. Hand loops should be attached from the inside to the bottom.

During diving, scuba divers can climb into the boat from the stern, unfastening the net. You can lower the rope ladder from the stern.

From such a boat it is very convenient to engage in fishing. The existing seat can be turned in any direction, which is especially convenient to do, if the backrest braces will be attached directly to the seat or to the seat and to the bottom. And besides it, you can put one or several folding chairs anywhere on the cockpit, providing their legs with a kind of “ski”. And if for skis provide loops on the bottom, then the fastening of the chairs will be fixed, but quite rigid.
