Description

The invention relates to individual life-saving appliances on water, mainly at sea.

As individual life-saving equipment on water, such means as a life jacket (stuffed or inflatable), an inflatable boat (as an emergency craft), etc. are widely known.

Known printed life jacket marine "ZhSM-CYCLONE" [RF patent for utility model No. 61249, published 02.27.2007]. The vest has a head restraint, a bib filled with a buoyant filler, a belt, a lifting loop and a towing loop.

Numerous designs of inflatable (gas-filled) lifejackets are known, for example ZhSM-2M; ZhS-AKR; ASJ; ASZH-63P; ZhVSN; ZhVSN-01; ZhS-M; ZhST; ZhS-11-M; JSSR [see, for example, links on the Internet: http://www.shtorm-spb.ru/zhs/; http://8456.ru.all.biz/zhilety-spasatelnye-rechnye-zhsrzhsdr-g1056182; http://pip-tur.tiu.ru/g354291-spasatelnye-zhilety et al.]. Vests are made of high-strength gas-tight material. Their various modifications can be equipped with a head-supporting collar, inguinal straps, special fasteners, locks, etc.

With all its simplicity and accessibility, life jackets have a common drawback - they cannot protect against hypothermia and from the attack of marine predators, because most of the body of a person in distress is not protected and is in the water.

From this point of view, inflatable liferafts and boats are safer and more comfortable.

Numerous rescue inflatable boats and rafts are known, including those equipped with awnings [see link http://odessa.olx.com.ua/iid-41268944]. Among life-saving equipment, individual inflatable boats that are part of rescue equipment — diving suits — are known. So in the SPES MK-10 models of BFA [see link http://www.uwt.ru/SisSp.htm]; or SEIE Mk-10 [See link http://en.wikipedia.org/wiki//Submarine_Escape_Immersion_Equipment], an inflatable boat is part of the equipment and is placed in a special bag mounted on a wetsuit. The disadvantage of this design is the complexity and bulkiness of the wetsuit itself, as well as the initial location of the inflatable boat in the bag. To bring the boat into working condition it is necessary to remove it from the bag, which requires time and hands free and undamaged in an emergency.

Also known are the designs of Berkley Tec Tube Belly Boat Pro Pulse inflatable boats equipped with straps for placement on the back [see, for example, the links http://nexus-kiev.com.ua/product/naduvnaja-lodka-berkley-tec-tube- belly-boat-pro-pulse /]. In this design, inflated boats are conveniently transported by land, but they are not suitable for use as a rescue tool.

Thus, the well-known life-saving appliances - lifejackets, are simple and convenient to use, but do not provide safety after a person ascends to the surface, and emergency watercraft - inflatable boats, provide relative comfort and safety, but they exist "autonomously", in isolation of the patient’s equipment human disaster.

As a prototype of the invention, the ZhSM-CYCLONE life jacket described above was selected.

The basis of the invention is the task of resolving the technical contradiction and creating a design of increased safety and relative comfort, and, consequently, increase the survival time of a person in distress on water. Achievable technical result - providing the possibility of transforming a life-saving tool such as a "vest" into a life-saving tool of the "inflatable boat" type and combining these two structures in one with enhanced functionality and increasing the degree of safety.

The problem is solved by changing the design of the life jacket.

The inventive rescue is made of water-tight synthetic material and has in the initial state the shape of a life vest. The chest shelves of the vest are equipped with buoyancy chambers, gas-filled or filled with elastic foam filler. The vest has waist and adjusting belts with quick-release fasteners, for example, fastexes or velcro (Velcro). It differs from the prototype in that it is additionally equipped with an inflatable boat with a bottom and inflatable balloons along the external contour. Moreover, part of the bottom of the boat is made integrally with the back of the vest (from one blank, or sewn with a second layer on the back part) and in the initial folded state is fixed to the back of the vest. The system of inflating the boat's cylinders provides sequential filling from the head of the boat. The vest can be additionally equipped with inguinal straps and have connectors at the shoulder seams.

The rescue tool may be provided with a cover protecting the inflatable boat in the assembled state. Sheets of the cover are fixed along the inner contour of the bottom of the boat with the possibility of transformation into a protective tent with the boat open. The bottom of the boat can be inflatable.

In order to better demonstrate the distinctive features of the invention, as an example, not having any restrictive character, the preferred embodiment is described below, which is illustrated by the drawings, which show: Figure 1 - rescue tool worn on a person, the initial state, Figure 2 - boat in the open state with a person on board.

In the initial state, the claimed tool has the form of a life jacket, sewn from a durable water and gas impermeable fabric, for example, nylon with polymer impregnation or a applied layer. The chest part of the vest has shelves 1 with buoyancy chambers filled with elastic foam filler. A gas bottle 2 with a starting system is fixed on the vest, which can be made automatic and triggered by contact in water or by a differential pressure signal, as described, for example, in the Parmaris manual [http://www.fordewind-regatta.ru/Inform /Parmaris/Parmaris.pdf]. Manual control is possible - with the help of a starting cable. The waist belt 3 and inguinal belts 4 serve for more reliable fastening of a vest on the person. Adjusting straps allow you to fit the vest more tightly to the figure.

An inflatable boat 5 is fixed on the back of the vest. Part of the bottom of the boat (head part) is the actual back of the vest. The rest of the bottom (most of it, because the boat is longer than the person’s height, which allows it to be in the prone position) and the inflated inflatable balloons of the boat in the initial state are folded behind the back of the vest and do not protrude from the bottom edge of the back of the vest from below. Thus, when folded, the boat looks like a backpack or satchel. To protect the boat from damage, it is equipped with a cover. The cover may be made of the same material as the boat. The cloth covers of the cover are sewn to the inner contour of the bottom of the boat and, when folded, the boats are partially turned outward and cover it, forming the outer packaging. The connection is made using a long cord threaded through the eyelets in the panels.

The boat’s inflatable balloons have compartments, and the boat’s balloon inflating system ensures their sequential filling, starting from the “head” part of the boat, that is, from the part in which the bottom is connected to the vest and on which the person’s head will be located when the boat is inflated.

A person who has fallen into the water floats to the surface and, thanks to the positive buoyancy of the chest shelves of the vest, lies on his back. When pulling out a long cord, the cover panels open and the boat opens under the action of gravity. Then, with the help of a starting cable (with manual control of inflation), a gas cylinder is opened. When performing the bottom of an inflatable boat, at first its part located under the back is pumped up, then the part located under the legs. After straightening the bottom of the boat and swelling of the water, the boat is inflated, again, starting from the head. Until the balloons are full, the person is lying at the bottom of the boat. After filling the cylinders, the victim can be released from the vest by unfastening the belts and disconnecting the connectors of the shoulder seams. Having taken a comfortable position, a person can, if necessary, assemble a protective awning from the panels of the cover, which can be fixed on the hinged support of the bottom. Prior to the arrival of rescuers, a person can be in a boat, if desired, in a lying position, and be protected from contact with sea water and with atmospheric precipitation, and closed from the wind.

Thus, the claimed device provides both the ascent of a person to the surface, and further comprehensive protection against external factors, and relative comfort, combining the functions of two commonly used autonomously used life-saving appliances. In this case, both the vest and the boat can be filled with gas from one source (cylinder) with a common control system. Due to the fact that the boat is mounted directly on the vest, bringing it into working condition is greatly simplified, and it takes less time. Moreover, the boat is mounted on a vest, it opens directly under the pop-up person, therefore it is guaranteed to automatically hit the boat, which significantly increases the degree of safety.
