Abstract

A dual-sided, or reversible, inflatable rescue and safety raft consists of an inflated grille provided with mesh netting spanning open regions to accommodate personnel, manually releasable locking devices that close access openings in the netting to permit personnel to board from underneath the floating grille, both surfaces of the grille being provided with fasteners for safety handles and belts; one or more containers with compactly folded modular floor and shelter units that can be fastened to the surface of the grille (or removed from the raft for use as tents on land) are repositionably secured to the grille in the event that the containers are submerged when the raft is initially disposed in the water.

Description

Rescue device, safety, allowing the reversibility of a life raft, shelter (s) -enterprise (s) which aims to improve the conditions of survival on a raft, to improve the quality of the rescue and the safety and create tent shelters that attach themselves to the raft as well as to the ground.

According to the background of the art, the purpose of PCT CH 99/00619 is to provide a greater area of impact on the sea than an ordinary lifeboat and to allow people who may be trapped under the device when it unfolds, to pass on the device and stay there, this thanks to openwork, unlockable, removable and lockable, allowing castaways to grab the net to join one of the openwork. It also allows if needed to cling to the device by the hands and feet to handles and use seat belts. However, nothing protects the survivors from bad weather in the cold sea, waves that can pass through the net, or the sun, and if the raft opens upside down, the castaways are deprived of handles and seat belts .

Again according to the background of the technique, document DE 32 10 590 A1 23.03.82, which is considered to be the closest state of the art, mentions a device in open water which is a buoy with multiple places, which has no net, tarpaulins cover a number of orifices and do not form a floor over the entire surface. Shelters are provided, but they are located on some units, they are fixed, can not communicate with each other and form multiple volumes.

The children can slide in the openings, the survivors can receive splashes, the water can stagnate on the tarpaulins and to form pockets there and if the survivors rush under the shelter, it will be created an imbalance and the multiple buoy goes to turn around, this phenomenon can be aggravated when mating units in a rough sea, because there is no guarantee that the shelters are placed head-to-tail in order to balance the loads, on the contrary in panic if unfortunately it does not It is not possible to perform such a maneuver, many people will also have to remain exposed to the weather.

The survival canoes that are found in the trade are of a modest surface, with a very limited number of people on board, the descents of plane, toboggans require a clever folding with a system of links yielding to certain pressure for that they open in the right direction.

The purpose of the present invention as described in the independent claim 1, is therefore to provide a safety rescue device that can overcome these disadvantages and disadvantages.

The advantages of the present invention reside in the fact that this life raft is made completely reversible thanks to male receiving fasteners distributed on both sides of the raft allowing the establishment of floors, removable shelters that can mate by bringing together several volumes or a single volume at the chosen location on the device, without wondering if the raft will open in the right direction.

Here is an example of execution and non-limiting use of the device. The present device consists mainly of an inflatable gate Fig.1, which deploys by means usually used in the field of inflatable, whose mesh 6 are lined with net 2 having unlatchable, removable and releasable openings 3, handles 4 and safety belts 5, which are distributed on the grid 1.

In a first step, during a shipwreck or flood, people trapped under the device that unfolds, unlock the openings 3 pass on the device, close ajourages Fig. 1.

In a second step, the shipwreck (s) stabilize (s) the raft by adjusting the ballast to the desired position Fig.12 a and 12b, If the raft has turned, the safety belts 5 which were attached when the raft has grown, are visible through the net. The castaways release the handles 4, which releases at the same time the seat belts 5, they pass everything on the device, either by the mesh of the net 2 if they are wide enough, or by the ajour 3 they will have open, either along the net attachment. They refix the handles 4 on the new location of the device; release one end of the bag, then the other, rotate slightly on itself to bring out the same path, the fixed on the place of the device through the receiving portion of the attachment 35 or 45, Fig. 11b, 12b, deploy the membrane intended to constitute a floor 7, Fig.1, and fixed with the means provided for this purpose, Velcro 10 for example, this to get a little more dry.

In a third step, the shipwreck (s) organizes (s) to mount a shelter 8 or individual or multiple shelters. A shipwreck unfolds the membrane which serves as a shelter 7, seizes the structure, in this example in the form of a spider 19, Fig.8, connects the muscular pump 20 on its end 24 in the structure, plunges the pipe 21 into the water, it can slide it between the floor and the side of the mesh of the grid, it pumps ... Once the rigid structure, he fixed the two uprights 22 on the edge of the mesh by Velcro 10 fixed on the grid, then it rises, deploys the following structure, then releases the bellows 17 held by fasteners 31, detaches the two removable posts 22 of the first structure to fix them with Velcro 10 provided on the top of the second structure, the bellows (17) opening to give the necessary length. Another shipwrecked man who has mounted a shelter next door, they decide to have more space, the side panels 18 are raised and are fixed one under the other under the roof of the nearby shelter by Velcro 10, they fix the base of the shelter with zippers 16 provided on the device They are then protected from the weather and can hold the handles 4 and attach with the seat belts 5. If water enters, they can empty it by lifting a corner of the floor 7.

In the event that they have to dock, and come to camp on land, they bring one or more sack (s) 11 and they will be able to establish their camp inland, thanks to the bindings, 14 loops distributed on one side of the bag. and on the periphery of the shelter 8 and the floor 7, FIG. 8.

This type of tent, which fits in an elongated bag, can be used with or without a lifeboat, in this case, it will not be useful to provide the ends of the bag with male fixings, but loops to fix stakes, the base of floors, shelters that can be fixed tightly together.

Regarding the fixings of the pans, the floors with the tubes, one can use fasteners, loops or buttonholes with buttons, straps with pressures, straps with buttons, Velcro, karabiners, waterproof zippers, eyelets with fasteners, this list is not exhaustive.

The membranes, floor and shelter are attached to the bag in every possible way. They are glued, heat sealed, sewn, riveted, then rolled, folded on themselves, held by straps with pressure, with fasteners, Velcro, carabiners, zippers, loops and buttons, this list is not limiting.

The envelope of the bags is provided with handle (s), thong (s), Velcro allowing to better seize them under the raft.

The two membranes are united in a bag, they are fixed one behind the other, the membrane floor in front and the membrane shelter, with its structure, behind. The bags are removably attached to the grid by means of male receiving fasteners 33 and 43 which are distributed both at the place and at the back of the device. The female fasteners 35 and 45 are fixed on the ends of the bags and fit into the male fasteners. These male fasteners are distributed over most or all of the grid and thus allow to put on the grid a number of bags 11 containing the two membranes, floor 7, shelter 8, which lightens the device because there do not have bags everywhere and leave the choice to plant your tent or tents where you want. It is the same for the handles 4, they are made removable by the same kind of male / female fasteners.

The removable fasteners for the bags containing the floor and shelter membranes, are half-cone shaped female receiving parts, for example 35, with an orifice 36. They are fixed on the flanges. In these receiving parts are interlocked for example, a pull tab system, spring tongue or with a push button 34. The button engages in the hole and fixes the bag to the grid. Fig. 11a, 11b, 11c. A variation of execution is a tongue folded on itself spring 43, with a space to place the thumb, this tongue is provided with two nipples 44 which fit into two holes 36 provided for this purpose on the piece receiving female fixed on the pudding. Fig.12a, 12b. These male fasteners are mounted at the ends of the bag or for example at the ends of a flexible flat strip fixed under the bag, a version may be adjustable in length, to fit any bag size, this band will be slipped into a hem open at both ends under the bag, this is not limiting.

The same type of receiving part can be made for the removable fixing of the handles, the two receiving fasteners being glued, heat-sealed on a plate or molded, the plate with the fastenings then being glued, heat-welded, to the pudding. Pulling the handle and pressing the button 34 or the tongue 43 releases the handle 4, one side then the other.

This type of fasteners can be adapted for fixing the edges, uprights 22 to the grid. It is also possible to use seatbelt clips, zippers. These examples are not limiting.

All bindings of the bags, handles, edges, uprights of shelters, fasteners of the floors will be arranged on both sides of the grid.

Variation: the bags can be made removable by a fastener consisting of a tube provided with a slot 32 fixed along the edge of the bag as a receiving piece and a firm bead 26 fixed on a piece of fabric 23 attached to the wire rack. The bead 26 is slid through the slot inside the tube. The bead may be in extension of the fabric or at a right angle, fixed in the middle of the fabric. Fig. 9a, 9b, 9c.

Variation: the bags can be made removable by fixing on the bag 11 sections of flexible tubes, rigid or elastic 28 Fig 10a with a series along the mesh, Fig. 10c the sections of the bag and those of the mesh being joined by threading a rod provided with an eye 29 FIG. 10b with a clip 31 to fix everything Fig. 10a.

Safety belts are made removable carabiners fixed at each end, which allows them to end and end and thus constitute chains, this is not limiting.

To make a raft reversible, the location of the bags and handles on the reverse side of the raft should be reported in one way or another, so as not to waste time finding and clearing the bags.

The ballast consists of strips of perforated fabric 27 forming sections, with in the middle of each band, lead 30, ensuring the stability of the ballast, and at each end of each band pleats accordion 41 and means for example rings 40 and carabiners 39 for hanging / unhooking the bottom of the band on the flange to form the ballast or release it by fixing it to the rings on the flange 52 by means of the carabiners. The rings 40 on the coil 52, are distributed on two lines on the top and on the bottom of the raft, to always locate the ballast under the raft where it is necessary. Fig.2a, 2b.

The membranes which are doubled as well as the structures, they can be equipped with anti-return valves if necessary and inflated either automatically or not by a generator of air / gas and / or manually with the pump with muscular force, this to create a insulation.

The tubular structures are semi-flexible and / or articulated since they bend to store, they can be constituted by folds of membrane, be included in the folds or reported on the structure. Tubes, flexible rods, which can be telescopic, articulable, curvilable, provided with ball-and-socket joints for pivoting or fitting into one another, can be inserted into the folds, hems, hems, this being not limiting. Pipes and sticks being flexible, they can be mounted directly during manufacture.

If the structures are swollen with water, provide antifreeze for injection into the structure, to be provided in the rescue equipment.

Depending on the choice of the user, some rafts are provided with a bag containing a telescopic rod mounted on a ball, with a sail and oars, rowing supports may be provided on the rods, it is also possible to provide a location to attach an engine.

The maximum load and the number of people expected will be clearly indicated on the grid.

The length of the membranes, floors and / or shelters, may be provided to occupy one or more meshes, or even the entire surface of the device or a raft may consist of only two meshes, with a shelter covering a mesh and the floor two meshes, this being not limiting, the assembly technique allowing the multiplication of volumes by mating on neighboring volumes, or if preferred can form individual shelters, distributed on the device according to our desire.

When creating large meshes, supporting a certain load, several people can stand shoulder to shoulder in two rows facing each other in the same mesh, the last two at each end cling to the handles. People are facing each other, in addition to seatbelts stand, feet against feet, during rough seas.

The H-shaped structure applies to parallelepipeds. The three-sided structure 37, of square (or rectangular) shape described in FIG. 7, also rests on a parallelepiped shape, the membranes of its sides 18 are liftable and comprise in addition bellows, accordion membranes 17 which allow the panels 18 to stretch forward so that they are long enough to be fixed on the top of the next shelter.

The cross-shaped structure Fig.8 also comprises panels 18 whose membrane is liftable and accordion bellows 17 for hanging its uprights 22 to the next volume.

It is not mandatory to attach handles on the side where the bags are attached. Between two shelters, in case of space, games, sealing will be ensured by fixing between the amounts, roofs, strips, fixed by Velcro for example. On some sections or roofs transparent membranes forming skylights 56 are laid. 6.

Depending on the diameter of the flanges, the floors will arrive either close to the handles or behind the handles, in this case, it will also provide to put buttonholes / slots 25 to let the handles 4, Fig.1.

Depending on the use, the tubes will be protected from friction by flexible reinforcement strips usually used in the field of inflatable.

The unlatchable, removable and releasable laces 3 will be made unlockable and releasable both over and under, for example by Velcro strips with a handle on each band. Pliers, pincer-type pliers, with a spring, long arms, wide, ergonomic that can be grasped by hand, one of the arms of the clamp being provided with a link to the net to prevent that it does not fall into the water, the jaws of the forceps surrounding the two lips of the ajourage. With a gripper, fully grippable whose arms, levers, are flexible 46, are mounted in a single block on an axis 57, each provided with a projecting portion 51, levers whose protrusions are fitted into a receiving part female 48 which is provided with two orifices 47 for receiving the two projecting parts 51, this type of clamp can be laid flat, Fig.13.

According to the standards and the technique in force for the lifeboats, the grid will be constructed by compartments and / or with an inner tube wall, these compartments will include one or more non-return valves as well as pressure relief valves.

Inflation systems are common. In the case where the manufacturer would choose a system with strap for detaching bottles and with several bottles. The straps will be guided by wheels, pulleys, ducts or any other room allowing the straps, cords to slide. These pieces will be attached to the strands, the straps, cords will be attached to a single handle, buckle visible from the outside of the container. The bottles will each be slipped into a protective pocket or fastened by straps or any other usual means. The grid contained either in a container or in a bag which will open, for example, yielding to the inflation pressure.

According to the standards necessary for the homologations in the countries, it will be necessary to equip the device of all that can guarantee the safety of the inflation of the raft and any rescue equipment usually used for the rescue, ropes on the rolls, ladders, anchor, kit armament, rescue and complete survival, accessories, reflective strips, rowing supports, etc.

A bag, fixed to the grid, with a floor membrane, with or without shelter, can be used to cover a pool and provide thermal protection.
