Description

Invention from the field of water rescue equipment. It can be used as an alternative to a life jacket and a life buoy as a rescue tool for long stays in water, including cold ones. It can be used as a means of rescue, which is used by crew members and passengers at the moment before the flooding of the ship or at the time of the emergency landing of the aircraft on the water.

From the prior art, various means of rescue on the water are known.

For example, lifebuoys are known that keep a person on the water (see patents US 3095568 A, US 6368174 B1, SU 472862 A1).

Also known are sectional life-saving appliances that hold a person on the water. For example, it is known an individual water rescue device (RU 52814 U, published: 04/27/2006) containing two sections connected to each other by a mount, characterized in that one of the sections is a standard configuration with a buckle-chamber at the waist level , and the second element is made of an elastic material in the form of a cylinder in the shape of the letter Y, while the buckle-chamber is filled with compressed gas, and the fastening unit is a membrane separating the chamber from the cylinder, a button and a punch, which, when the button is pressed, pierces the membrane with the possibility of filling gas cylinder from the chamber.

The closest analogue is the application RU 96120590, published: 20.12.1998. It describes a lifebuoy containing a floating body, consisting of two sections connected to each other by means of attachment points, as well as a lifeline attached to it, characterized in that the sections of the floating body are made of an elastic material, while the contacting end surfaces of the sections of the floating body are provided with textile ''velcro'' fasteners, and the functions of the attachment points are performed by loops in the form of linings of flexible elastic material attached near the contacting ends to the lower surface of the sections of the floating body and quick-release fasteners "buckles" attached near the contacting ends to the upper surface of the sections of the floating body body.

The technical problem of the known means of rescue is that they only provide for keeping a person on the water, but do not allow him to stay in cold water for a long time, while remaining dry. This limits the time a person is able to stay alive on the water, especially if the water temperature is low.

So at a water temperature of +24°C, the safe stay time is 7-9 hours, at a water temperature of +5 - +15°C - from 3.5 hours to 4.5 hours. If the water temperature is +2 - +3°C, it turns out to be fatal for a person after 10-15 minutes, and at a water temperature of -2°C, death can occur in 5-8 minutes.

Thus, the known means of rescue require, in fact, the immediate rescue of a drowning person, which is not always possible.

The objective of the invention is to eliminate these technical problems.

The technical result of the invention is the possibility of a long stay in water, including cold water.

The specified technical result is achieved due to the fact that the water rescue means, containing a floating body, consisting of two sections connected to each other, characterized in that the floating body in its middle part has an elastic waterproof bottom, and the central part of the bottom is formed in the form of an element a waterproof suit for the lower body of a person, including at least his legs and pelvis.

Sections can be fixed between themselves hingedly or with an elastic bottom.

Preferably, the sections of the floating body are made in the form of U-shaped sides.

Preferably, the end edges of the U-shaped sides contain means of fastening to each other.

Preferably, lifting tents are fixed on the outer edges of the sides of the sections.

It is permissible that oars are fixed on the sides of the sides of one of the sections.

A water rescue method is also claimed, in which the above-described rescue means is used in such a way that until the moment of immersion in water, a person is placed between two sections of a floating body, legs in a waterproof suit; at the moment when a person is on the water, they achieve his position with his head up and legs in the water, and hold him to the state until both sections of the floating body are joined by the ends of the sides.

If necessary, awnings additionally fixed on both sides of the sections are used, which cover the floating body over the head.

Implementation of the invention

The invention reflects a means of rescue on the water, containing a floating body, consisting of two sections 2 connected to each other (see Fig.1, Fig.2).

What is new is that the floating body in its middle part has an elastic waterproof bottom 4, and the central part 5 of the bottom 4 is formed in the form of an element of a waterproof suit 1 of the lower part of the human body, including at least his legs and pelvis.

Sections 2 can be hinged, elastic bottom or otherwise.

The sections 2 themselves can be of various shapes. The most preferred and convenient form are sections that are made in the form of U-shaped sides. If the end edges of the U-shaped sides also contain means of fastening 3 with each other (for example, Velcro), then this makes it possible to reduce the periodic separation of the ends during strong waves on the water.

In order to protect the person 6 from cold and precipitation, it is preferable that lifting awnings 7 are fixed on the outer edges of the sides of the sections 2 (see Fig. 5). These awnings 7 cover the floating body over the head.

The water rescue method consists in using the above-described rescue means in such a way that, until the moment of immersion in water, a person 6 is placed between two sections of a floating body (see Fig. 1), with their feet in a waterproof suit 1. At the moment when a person is on the water 8 , achieve its position head up and feet in the water, and hold it to the state until both sections 2 of the floating body are joined by the ends of the sides.

The claimed invention can be used as a means of rescue, which is used by crew members and passengers at the moment before the flooding of the ship or at the time of the emergency landing of the aircraft on the water.

The bottom element 4 in the form of a suit 1 is, together with the sections, a collapsible capsule in which a person 6 can be on the water in a sitting position. This system is unsinkable, easily portable, makes it possible to walk on land and on the deck of a ship or aircraft. In water, it completely protects a person from the external environment and allows a person to stay in cold water for a long time, remaining completely dry.

In contrast to the well-known means of rescue in the form of a vest or a circle, the claimed invention allows you to stay dry for a long time in cold water, you can also install a radio beacon for quick search and rescue.

The person stays dry because his feet are inside the waterproof suit, and the waterproof bottom prevents water from entering the body through the top. Thus, it is possible to stay in water for a long time, including in cold water.

In the event of a danger of a shipwreck, flood, or in case of an emergency splashdown of the aircraft on the water, a person needs to put on a waterproof suit 1 over clothes (and even over shoes) and fix an unsinkable platform from sections 2 on himself, or hold it with his hands along the edges of the sides (see Fig.1).

Next, the person 6 can move freely on the deck of the ship, or on land until it enters the water (see Fig.2). Once in the water 8, the sections of the floating body are opened under the weight of the person's legs submerged in the water, because the sections themselves remain buoyant on the water. At the moment of disclosure, both sections 2 of the floating body are joined by the ends of the sides. It is desirable that the end edges of the sides contain means of fastening 3 with each other, which makes it possible to reduce the periodic separation of the ends during strong waves on the water. So that a person can move in the water himself (for the purpose of self-rescue in order to be able to swim to the shore), oars can be fixed on the sides of the sides of one of the sections.

For rescue equipment intended for use in cold waters, it is preferable that lifting tents be fixed on the outer edges of the sides of the sections. These awnings cover the floating body over the head in case of cold or precipitation. Then, the top of the awning rises and covers the body partially (see Fig. 3) or with the head (see Fig. 4).

According to the invention, a prototype was made, which was successfully tested, including at sea in winter (see examples of testing a prototype in Fig.5 - Fig.9).
