Abstract

The invention relates to inflatable structure(s) comprising large openings which are formed by construction elements that can be used to dimension a base module. The aforementioned module comprises means which can be used to increase the number of surfaces of same. According to the invention, some or all of the inner peripheries of the large openings may or may not be equipped with a band of fabric comprising fixing means which are used to fit accessories, netting, a sail, cords, handles, thereby enabling multiple applications.

Description

STRUCTURE (S GON LABLE (S

Inflatable structure (s) ₅ formed from tubes, between which there are large openings. The surface of these structures is created by multiplying the elements which constitute its members, crosses, angles, tees, curves, thus creating a basic module usable in itself. The module thus formed comprises on the internal periphery of at least one of these openings, or even Roads, a strip of fabric associated with fastening means, which strip of fabric is affixed to the rod, at the height where it is desired to fix net, canvas, accessories.

To this surface is added, if desired, a bridge, on which one can walk, which bridge is reproduced, on as many faces of the base module, where one wishes to increase the number of large openings.

The state of the art mentions the document WO 01/06076 A1 mentions an inflatable grid, all the openings of which are provided with a net with unlockable, retractable and re-lockable openings, grid which applies to liferafts, playgrounds and swimming pools. The fixing of the net, as described on page 9, line 26 does not resolve the fixing of the net, the eyelets are placed directly on the extension of the junction of two superimposed fabrics, thus weakening the structure Fig. 3.

SWIMMING POOL

In this same document, the problem of ballast, for the return of the grid to the bottom of the pool, is not resolved, the surface of the deflated tubes flat on the water require ballast, heavier materials. On the other hand, during a grid constructed in sections, in the inflated and juxtaposed position, nothing allows you to walk on the junction without getting your feet between the two tubes.

Document FR 2 505 914 mentions a rigid frame going around the pool, on which a net is stretched, covering the entire pool, with a float which brings the frame up to the surface. The rigidity is not resolved, a frame thus designed can only bend under the load.

Publication WO 03/015046, mentioned on page 9, of an extendable frame, situated around the perimeter of the grid, used to stretch the net. The frame is housed under the tubes, at the axis of these, which causes a gap of 15 to 20cm, depending on the diameter of the tube, between the frame and the edge of the pool, a member, arm or foot may get caught between the frame and the edge of the pool during the ascent.

SURVIVAL RAFT

The document DE32 10590 Al faif; mention of a life raft made up of units attached by hooks. The junction of the surfaces does not allow walking on the junction of the two surfaces. Document WO02 / 079027 mentions a reversible life raft in a single unit _^

SPORT GROUND

For sports fields, the state of the art mentions aquatic trampolines, these trampolines generally consist of an air chamber, with an opening in the center which comprises a canvas on which one jumps and bounces thanks to the fasteners which are either springs, elastic cords, or both, and mounted on a rigid tube: US documents

5,810,695, US 6,508,682. They are designed so that one jumps mainly on the single canvas, carpet, and there is no provision for quick installation and removal of the rebound canvas to allow other activities. Document US 6,223,673 mentions a trampoline to which is added an access ramp and two joined tubes to form a slide. It is designed so that you jump on the mat and use the access ramp to grip and climb on the trampoline and the slide to get off. These trampolines limit the possibilities of activity and are not designed to allow the establishment of games other than the trampoline games or the games which consist of getting in and out of the trampoline.

In the case of the inflatable structure presented here, it is the structure itself which reacts, whereas for the usual trampolines, the structure is rigidified by a tube and it is the tension on the elastic cords and / or springs which rebounds. On the other hand, this inflatable structure allows the creation of a basic multiple play surface, the installation and removal of nets, fabrics, accessories is fast, surface which can be multiplied on each of its sides thanks to a bridge.

SNOW APPLICATION

Document US 4,894,033 mentions an inflatable mattress usable on snow. If the oars Fig. 9 and guide elements 22, Fig. 2 are used to direct the mattress, given the position of the body imposed by the shape, there is no braking means.

Document US 4,206,933 mentions a sled whose inflatable structure is of triangular shape, whose driving during turns is not ensured.

Figure 26: shows an example of attachment of the net 18, by means of mini mooring bittes 66 fixed on a strip of fabric 10 and with on the net loops 70

Here, as an indication and without limitation, some examples of executions of this inflatable structure.

- For example, a basp module consisting of twelve openings, here rectangular, of which six openings 5 are without fabric strip with eyelets, four openings with fabric strips 10 and eyelets 7 covered by protective strips 49, and two openings with of the net 18. Fig. 11.

- A variant would be the same structure with strip of fabric 10 and eyelets 7 provided with strip of protective fabric 49, ready to receive net, accessories, and this in all the openings 5.

- A variation would be the structure with all the openings provided with a strip of fabric 10 and eyelets 7, protective strip 49 and with net 18. Fig. 10, Fig. 20.

- Another variant, a module without fabric strip 10 with eyelets 7.

Each module can be used in itself and a bridge 9 is created on each of the sides, where it is desired to add another surface.

REMOVABLE NET

The net is made removable by a simple fastening system. See fig. 4 d-4 e, Fig. 7. For the net, other removable fixing means, for example the use of double hooks 17, carabiners è. hitting non-crushed, carabiners, ropes 11, loops 70, Fig. 26, hems for rope, this not being limiting.

The fixing of the net described in Fig. 4 d and 4 e is particularly quick, once the length of the loop defined, it can be fixed to the base, by glue or by a ring for example, the loop is then pass in an eyelet, it is folded to the left and the next loop passes in this loop, and is folded to the left, so on. A piece of rope hanging at each end, just tie in the corners, the end of the two cords together, to fix the net, canvas. Disassembly is done just as quickly. It is the same for the technique shown in FIG. 4 g. OPENINGS PROVIDED WITH ONE NET

The fact of fixing, a strip of fabric 10 with fixings, and protective strip 49, with accessories like rope 11 or footrest 16 for example, FIG. 5, 6, in certain openings 5 or in all the openings 5, creates a new effect and allows its use both in aquatic environments, and on a beach on soft ground to develop ball games, skill, races , saltos, this list being left to the imagination.

The structure can thus form a large checkerboard which can reach, in one piece, or in several parts connected by a bridge, the size of a volleyball court or more.

TAPE OF FABRIC ASSOCIATED WITH MEANS OF FASTENERS This strip of fabric 10 with eyelets 7 or fasteners consists of a long strip of fabric, which is folded in half lengthwise from the fold thus formed, approximately d 'a third to a half is attached, glued 33, on this part are fixed, all along the strip, the eyelets 7 or fixings, hooks, mooring bittes, hem for rope for example. The non-welded part, glued 33, is separated in two, open and is fixed, glued, against the flange 8 FIG. 2, A strip of protective fabric 49 is glued to this strip of fabric 10, in that of the bindings, it is floating and comes to cover the bindings, ropes. According to the solidity of the materials used, the fabric strip 10 will be reinforced, for example, by at least one seam 65, and that of the fixings FIG. 7. The seam is made either on the fabric strip 10 or on the protective strip 49. If the protective strip 49 is not heavy enough to cover the ropes, it will be fixed to the net, canvas by a few ties by example. This applies to any type of structure, swimming pool, life raft, playground, sledges.

If necessary, depending on the tensions, pulls, on the tubes, which the strip of fabric 10 will have to undergo, it will be covered in its upper and lower part with a strip of fabric glued to its limit on the roll and coming to cover for a few centimeters. the strip of fabric 10.

This strip of fabric 10 with eyelets 7 or fixings, can be used both on the internal periphery of the structure for accessories, for example a footrest, of the net, canvas 18, and on the outside, below the structure to fix the weighted net 47, by means of ropes, hooks. Fig. 2, 4 e, 5, 6, 7, 8, 9, 10, 11, 12, 15, 16, 20, 22, 26. Depending on the size of the tubes and activities chosen, the same strip of fabric 10 with fasteners and strip protection 49 is fixed at several desired heights, thus increasing the possibilities of use. Note: it is the diameter ratio of the tubes, surface of the net, canvas, and position in height of the net, canvas, which determine the contact with water or not and its use, rescue or games.

Using the high frequency, ultrasonic welding technique, the strip of fabric 10 with eyelets 7 is in two parts which are grafted onto a seam, on this strip are attached handles, accessories, ropes, ladder, eyelets, fixings, at choice. Fig. 8.

HIGHLIGHTS

For safety, the projecting elements added on the top of the structure which can injure the human body, such as dps rings 64 (in a semicircle,) of the rope passes, for example, will also be covered by a protective strip 49 or by a other means of protection such as foam blocks, cork, caoμtchouc for volleyball uprights. Fig. 25.

FELET AND FASTENERS

The net, canvas 18, for example esj: itself either cut clean, or for more solidity it is bordered by an overlock, a rope 11, rope with loops 60 coming to intertwine in the eyelets 7 located on the fabric strip 10, Fig. 4a, 4d, 4th; of loops 70 which can be hooked on the mini mooring bittes 66, hooks, located on the strip of fabric 10 FIG. 26; a hem or other strip of fabric 10 with eyelets 7, FIG. 22; or other fixing means, double hooks 17, Fig. 7, 21 a, b, c. elastic cords, for example.

The fasteners on the fabric strip 10 are for example: hooks in the form of mooring bittes mounted on the strip 66 or directly on the fabric strip 10, eyelets 7, FIG.

2, 7, 26. for attaching net, canvas, accessories, footrest for example Fig. 6.

UPRIGHT HOLDER FOR VOLLEYBALL

On each side of the bridge, left - right, a board 61, slipping into hems, pockets 62 provided for this purpose, over the bridge fixing device chosen. On the middle of this board, a tubular part 63 into which will be screwed, fit the amount which will carry the net. The rope passes, here dice rings 64, will be arranged on the sides of the bpudins 8, on the structure, to allow, using cords to stabilize the uprights and the net, a strip of fabric 49, which can be cast off, cover the dice rings, Fig. 24. Variation of execution: flag-holders in the shape of cones, glued either directly on the structure if it is built in one piece, or on a board 61, this not being limiting.

INFLATION / DEFLATION SAFETY

Each structure is provided with at least one inflation / deflation valve 19 corresponding to an air chamber, each valve supplying an internal section of the structure separated by a wall placed where desired.

When the structure is used pn creating a closed universe, or far from a shore, in particular for lp sports ground, it comprises in its nets, fabrics, separable openings, which one can unlock and re-lock Fig. 20.

For independent sports grounds, or swimming pool covers independent of a rescue device, inflation / deflation is done by means of an inflator usually used in the nautical field, or a pneumatic vacuum cleaner with reverse functions.

SURVIVAL RAFT

In the case where the spreadable, unlockable and re-lockable openings are made waterproof by any means, waterproof zipper for example, the net is replaced by waterproof fabric on which will be created the spreadable, unlockable and re-wettable openings. This fabric will be fixed either directly on the flange with a protective strip glued, welded, on the flange and coming to cover the part of the canvas fixed to the flange, or the canvas will be glued welded on the fabric strip 10, which will be fixed to the desired height, these fixing means are applicable to the sledge.

The saç will then include either only the shelter, tent, or a shelter, tent with floor and means of land fixings, depending on the intended use.

OVERPRESSURE VALVE

In addition to an inflation valve, deflation, according to the use that is made of it, it is possible to fix a pressure relief valve, so that in the event of violent shocks, the air escapes without making explode the sausages.

TRANSPORT

To this end, the basic module is provided, on its periphery, with strings 11, handles 15. The same is true for all applications. On the other hand, the transport of the deflated module is done either by means of a tarpaulin, straps, and handles 15 fixed on the outside of the tarpaulin, the whole being placed on a skateboard. Another solution: make a cover in the shape of a large suitcase, crate, mounted on a wheeled plate 42, with a closing system, zipper, or straps 43 and / or, handles 15.

BRIDGE

The creation of a bridge 9 applies to swimming pools, sports grounds, liferafts. The junction between two surfaces must give a certain rigidity to the whole, because the bridge 9 created, by any means whatsoever, is designed to avoid getting caught between two flanges 8, when racing balanced or jump between the tubes 8.

Fig. 3, 4c, 4f, 4g.

Two modules can be attached by passing a rope 11 through the handles 15, however it will be necessary to create the bridge by fixing:

Solutions a and b: a strip of fabric 13 with eyelets 7, floating, fixed on one side on a flange and opposite on the other structure, a strip of fabric 13 placed astride the rope which comes out in loops 60 by the eyelets 7. Fig. 4 a, 4 b, 4 c.

Solutions b and c: two strips of fabric 10 with eyelets 7, fixed on either side of the tubes that we want to assemble, either the two strips 59 overlap, and a cord 11 is passed over - below the two strips of fabric, Fig. 3, or the two strips of fabric with eyelets 13 are placed edge to edge and a rope 11 passes in a zigzag to assemble them, FIG. 4 f.

Solution d: two sets of mooring bittes 66, each on a fabric strip 67 fixed to each rod that we want to assemble, and a rope passing from one mooring bead to the other Fig. 4 g.

In all cases, a strip of fabric 49 will be fixed to one of the strips of fabric 10 and will cover the fasteners. This fabric strap 49 folds down when the rope is placed.

So that the flanges 8 touch each other during assembly, it is useful to locate the handles 15 in staggered rows, from one module to the other. POOLS, BALLAST OF THE STRUCTURE i

For the application in connection with a pool rescue device, the solution for the ballast of the grid is to establish not a simple frame, but a second metal grid located under the inflatable structure. The grid has fittings, angles 25, tees 23, cross 24 allowing its assembly / disassembly on site, it is attached to the inflatable structure by strips of fabric 26 in which the uprights, bars 22 slide. The outer periphery of this second grill will be fixed so that the grill is as close as possible to the edges of the pool. Fig. 13, 14a, 14b.

This metal grid, in its fabric sheath, either rests on the bottom of the pool, when the inflatable grid is deflated, spit it comes to be embedded in the floor of the pool where its imprint is reproduced.

THRUST

To avoid the stops of the metal grid against the walls of the swimming pool, it will be necessary to provide elements, protective strip n rubber 68, to avoid friction. As a variant, the abutment elements will either be fixed at sensitive locations around the periphery of the grid, or on the walls of the swimming pool.

ACCESINTERNEALASTRUCTUREr

To manage the installation of the air distribution network to access the interior of the structure is ensured by watertight hatches are fixed on the crosses, tees, angles, in the installation of the rescue device.

PHROHIBE / SECURITY ACCESS

When you want to prevent you from swimming under the structure, for sports grounds placed in the middle of a swimming pool or on a body of water with clearances around it, you must install fixing means positioned on the periphery bottom of the structure for hanging weighted net 47 around the entire periphery, which weighted net 47 will descend to the bottom and prevent access to the area. These means are, for example, rope passes with a rope going around the structure, dice rings, that is to say in semicircles, loops, fixed, at regular intervals on the lower periphery of the defined surface. Hooks, or small carabiners will allow the placement of the net, this is not limiting. Ballast can be done, for example, by a tape containing lead surrounded by insulating material. Fig. 20 or weights. AMMARRAGE

These playgrounds, in aquatic environments, swimming pool, lake, sea, are moored thanks to ropes, dead bodies, to ensure their stability.

REINFORCEMENT STRIP

When the structure is likely to be in contact with friction, feet, ground or rough elements, walls of the pool, whatever its application, it is recommended to place reinforcing strips of rubber 68 or other material which assembles with the fabric used to make the sausages, and this, in any location which is likely to be worn, on the sides, the bottom, the top, Fig. 16.

SEAMS

When using to make the sausages either the cold bonding technique or a mixed technique; the internal and external seams will be reinforced with strips of fabric to allow a perfect seal.

REINFORCEMENT OF THE INFLATABLE STRUCTURE When using the technique of thermo welding, by high frequencies, ultrasound, the inflatable structure, tubes, is reinforced by incorporating tubular elements 57 such as they are found on air mattresses. The fixing of the strips of fabric 10 with eyelets 7, or strip of fabric to form handles, is done on a reinforcement, extension of the seams 58, FIG. 8.

SNOW-WATER APPLICATION

A structure in the form of a boat, with reinforcement strips, below, sides, where there may be friction; one or more crosspieces 28, of canvas or net 18, fixed by means of either a strip of fabric 10 with eyelets 7 and a rope 11 or double hooks 17, or by means of two strips of mooring bittes and a rope, structure provided with handles 15, seat belts 29, with a rudder system and brakes, becomes a sledge, a bop, for hitting, climbing snowy slopes. The brake and rudder system is removable. The advantages are that the bob is removable, deflates, takes up little space, folds and stores in a bag and that one is protected by the tubes. We can sit either in the canvas or on the sleepers, for more comfort, for example, we can provide, an elastic net to carry luggage fixed along a sleeper, footrests, fixed, glued on the internal sides on either side of the tubes, either for seated or standing driving. Fig. 15, 16, 17a, 17b, 18a, 18b.

In summer, it can be used on the water, a motor can be fixed at the rear as well as oars. A canvas, bordered with eyelets 7, will be made waterproof in any way, for example: a strip of fabric 54 is fixed, at the edge of the strip of fabric with eyelet 10b, it covers them, and is applied , by making the angle and going up on the sausage where it is fixed thanks to a series of buttonholes 52 which are on the strip of fabric 54 and which is hooked on the sausage 8 where there is a strip of buttons 53 mounted on a rubber band. The fabric strip 54 includes a suction cup strip 51. FIG. 22. The strip of fabric 54, folds down to allow attachment to the canvas.

The buttons can alternatively be flat hooks. Another solution: a waterproof zipper fixed on the one hand to the flange, and on the other hand to the strip of fabric with canvas, this not being limiting.

GOUVERNAIL - BRAKES It consists for example of a handle, articulated and foldable rudder tube 30, with a handlebar 31, is adjustable in height. Its position in height is arrested by a metal rod 35 which passes through the holes 34 provided on the handle of the rudder 30. FIG. 17a.

The handle 30 engages freely in a transverse axis 32, which axis is extendable or not in width and which comprises in its lower part and at each left, right end, a rod 40, threaded or not which each come to fit in female supports 41 fixed on either side to the internal front of the bob. Fig. 17a, 17b. The threaded rods are used to receive nuts or fins.

The handle 30, crossed by a metal rod 35 is placed freely on the transverse axis 32 and so as to be able to rotate the assembly.

Another variant for supporting the rudder: a part adapted to the internal or external front of the tubes forming the sledge, comprising a tubular part 56 to receive the rudder handle 30, the upper part of this part will include a platform 57 on which will come place the rod 35 threaded into the rudder handle 30. Fig. 23. To avoid too much floating, a circular cavity, representing the pivoting of the rod 35 is predictable either on the transverse axis 32, FIG. 17 a, either on the platform 57 of the support, Fig. 23.

FIXING THE BRAKE SYSTEM

On the lower part of the handle 30 is fixed hooks 38, or loops on which are fixed either springs or large elastic bands 37, which are themselves fixed by means of crophets 38, thus connecting the handle 30, to a plate serving as brakes 36. Fig.17a.

The springs or large elastic bands on the back of the plate 36 are shorter and / or have different traction forces so as to brake according to a progression.

The rear part 39 of the plate 36 is flexible, brushes against the snow, so that by keeping the handlebar 31 straight, the raft in the snow spins straight, moreover a reference point can be fixed at the front , at the junction of the two tubes. An opening will be left in the canvas to pass the feet.

A little above the part which brushes against the snow, a toe clip is fixed 44. The part which follows the flexible part 39 is connected either by a joint, or by a hinge, or it is made of the same more solid material, during wear it is desirable to be able to change this part. Fig.17a,

18a, 18b.

ANOTHER SOLUTION TO CONSTITUTE THE BRAKE

A strip of flexible Z-shaped material, 46, fixed between two plates 36. FIG. 18a. The upper plate 36 has on its outer edge, hooks 38 which allow the fixing and suspension of the braking plate 36, which is connected to the flanges, by means of strong elastic bands 37 or springs 43, which are fixed on hooks 38 located on the flanges 8, at the desired height.

BRAKING

You brake by pressing the plate 36 with your feet, either with your left foot, or your right, or both, the more you climb with your feet on the plate 36, the more you press hard and the more you brake.

CONDUITEMANUELLEDELALUGE

As a variant, the rudder handle 30 is ruled with the hands, from the handlebar 31 by cables, springs, pressing on two brake plates or a handle mounted directly on a brake / guide plate 36 which is held straight to go right, and that we tilt slightly to turn, braking is done by more or less strong pressure on the handle. The bob then behaves, either standing or sitting. Fig. 23. For driving by force of the arms, foot rests 71 Fig. 16, on either side of the tubes, on the internal face of the sledge will be fixed.

It is possible to build bpbs, sleds in one place, multi places, with either canvas in each place, or in only one or two places, or without canvas, if desired, foldable seats or not will be fixed against the sleepers, either glued, welded, or by means of type 41 fasteners, Fig. 17b, for example.
