Abstract

The invention relates to inflatable structure(s) with large openings, the constructive elements of which permit a base module to be defined. Said module comprises means to permit application of multiple identical surfaces, the surface thus generated being provided or not with a strip of material having eyelets provided or not with a net, with or without accessories which permits the carrying out of a number of sporting, educational and leisure activities.

Description

GONLAB E STRUCTURE (S)

Inflatable structure (s), formed of tubes, between which there are large openings. The surface of these structures is created by multiplying the elements that constitute its members, crosses, angles, tees, thus creating a module. Each of these surfaces is usable in itself, surface to which is added a bridge, on which we can walk, which bridge is reproduced, on as many faces of the basic module, where we want to increase the number wide openings.

This inflatable structure, including the wide openings, by their options, with or without fabric band with eyelets, with or without accessory, with or without fillet or canvas, in certain openings or in all the openings, with or without one or more attached surface (s) allows multiple activities, as well in aquatic environments, as on a flexible ground, made up of sand, grass or snow for example.

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 6, Fig. 3 and page 9, line 26-27, does not resolve the attachment of the net.

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.

The publication WO 03/015046, mentions on page 9, of an extendable frame, located around the perimeter of the grid, used to tension 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 limb, arm or foot can get caught between the frame and the edge of the pool during the ascent.

SURVIVAL RAFT

Document DE32 10590 A1 mentions a liferaft made up of units attached by hooks. The junction of the surfaces does not allow walking on the junction of the two surfaces.

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, or elastic bands, or both, and generally mounted on a rigid tube; documents US 5,810,695, US 6,508,682. They are designed so that one jumps mainly on the single canvas, carpet. 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 activities and are not designed to make it possible to establish games other than the trampoline games or the games which consist of getting on and off the trampoline, moreover the canvas, carpet, is not not in contact with water when you jump on it and not to be refreshed.

In the case of the inflatable structure presented here, it is the flanges and the structure itself which reacts, whereas for the usual trampolines, the structure is stiffened by a tube and it is the tension on the elastics and / or springs that makes the rebound.

Here, as an indication and without limitation, some examples of executions of this inflatable structure. - A basic module consisting of twelve openings 5, here rectangular, of which six openings 5 are without strip of fabric with eyelets, four openings 5 with strips of fabric and eyelets 10, including two openings with thread 18. FIG. 11

- A variation would be the structure with all the openings provided with a strip of fabric and eyelets 10 with thread 18.

- Another variation would be a module comprising six openings, provided with a strip of fabric and eyelets 10 and a net 18, with on one side fastening means for another module, here a strip of gripping fabric 13. FIG. 10

These forms of execution can be defined as follows:

"The basic module, defined according to the shape and surface chosen, is an inflatable structure made up of tubes 8 which has, between its members, large openings 5, a structure whose inner periphery of the large openings is not provided with a strip of fabric with eyelets and net, with or without other attached surface.

• The basic module, defined according to the shape and the surface chosen, is an inflatable structure made up of tubes 8 which has, between its members, large openings 5, the inner circumference of the large openings of which is provided with strips of fabric with eyelets 10, which allows in aquatic environments, the addition of accessories such as ropes 11, footrest 16, handles 15, which are supports usable by the participants as well as net 18, which is made removable by a system of simple fixings. For the net, the removable fixing means are, for example, the use of double hooks 17, carabiners to strike without being crushed, carabiners, ropes 11.

• The two modes of execution mentioned above can be mixed, as in the examples mentioned above.

OPENINGS WITH OR WITHOUT NET

This applies mainly to sports grounds. - The fact of not fixing a strip of fabric with eyelets 10 in an opening 5, creates a new effect and creates new activities, for example on grass, sand, running in balance, jousting, gymnastics, acrobatics.

- The fact of simply fixing the strip of fabric with eyelets 10, without placing a fillet, but using the eyelets 7 to place accessories, ropes 11, footrests 16, handles 15, creates a new effect and new activities, balance on these elements, support for synchronized swimming.

- The fact of fixing, by means of the strip of fabric with eyelets 10, of the net 18 in certain openings 5 or in all the openings 5, allows in aquatic environments, 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 two parts connected by a bridge, the size of a volleyball court.

FABRIC STRIP WITH EYELETS

This strip of fabric with eyelets 10 consists of a long strip of fabric, which is folded in two, lengthwise, from the fold thus formed, about half is joined, glued, on this part are fixed, all along the strip the eyelets 7. The non-welded, glued part is split in two, open and is fixed, glued, against the flange 8 Fig.2. The basic structure, comprising the flanges 8, with a defined number of openings, is constructed; then the strip of fabric with the eyelets 10 is affixed against the tubes 8. Fig.2.

This type of attachment can be used both on the perimeter of the structure, to fix either a bridge 9, or accessories on the outside, or either inside the openings, for the laying of net 18, by means of cords , hooks. Fig. 5-. 6, -7, -8, _^ 9, -10, -11, -12, -15, -16, -20.

NET The net 18 is itself either cut clean, or for more solidity it is bordered by a rope 11 or a strip of fabric with eyelets 10. It is then attached to the strip of fabric with eyelets 10 fixed to the sausage with double hooks 17 or a rope 11. If you want to use an openwork fabric as a net and not extensible, the springs will be usable. HOOKS

Double hooks 17, the shape of which will vary depending on the assembly option chosen, see examples in Fig. 21a and b, 21 c, they will either be flat with rounded edges so as not to injure the feet, or of cylindrical section.

ACCESSORIES

Removable accessories, ropes 11, foot rests 16, handles 15, double hooks 17 for net 18, are placed on the fabric strip with eyelets 10, inside or outside the structure.

Accessories are then attached to the top of the structure, at the customer's request, such as upright doors, loops, rope loops, dice rings, portions of gripping fabric, to create sports fields that are used for ball games. , volleyball, jousting by falling into the nets, gymnastics, acrobatics along the sleepers, saltos from the sleepers and falling back into the net.

INFLATION / DEFLATION Each structure is equipped with at least one inflation / deflation valve 19. For independent sports grounds, or pool covers independent of a rescue device, inflation / deflation is done by means of an inflator usually used in the nautical field.

TRANSPORTATION For this purpose, the basic module is provided, on its periphery, with ropes 11, handles 15, of shape usually used in boating. 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, mounted on a plate on wheels 42, with a closing system, zipper, or straps 43 and 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.

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 a strip of fabric on the junction of the modules which will be fixed, either removably, from either side, or from fixed way on a module. Fig. 3 and 4.

When it is desired to assemble two surfaces by passing a cord 11 through the handles 15, it is useful to place the latter in staggered rows, of a module relative to the other flange 8 which it is desired to assemble, so as to what the two flanges 8 touch. Fig.4.

Another solution: two strips of fabric 49, comprising eyelets 7, each of these strips is fixed respectively to a strand of a structure that we want to assemble, a rope 11 is passed through the eyelets 7, above, below, with a knot 12 at each end Fig. 3.

BALLAST OF THE STRUCTURE

For the application in connection with a pool rescue device, the solution for the ballast of the grid is to establish 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 grid will be fixed so that the grid is as close as possible to the edges of the pool. Fig. 13, 14a, 14b.

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

To avoid the stops of the metal grid against the walls of the pool, it will be necessary to provide rubber protection elements, to avoid friction. These elements will either be fixed in sensitive places around the perimeter of the grid, or on the walls of the pool. PHROFFlBE / 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 on the bottom and prevent access to the area. These means are, for example, dice rings, that is to say in semicircles, loops fixed at regular intervals on a strip of fabric attached to the lower periphery of the defined surface. Hooks, or small carabiners will allow the placement of the fillet, this is not limiting The ballast can be done by a tape containing lead surrounded by insulating material. Fig. 20.

The openings of nets provided with unlockable and re-lockable openings, mentioned in the document WO 01/06076 A1, apply to an enclosed environment, sports field with dimensions of the swimming pool, or sports field of which the enclosed environment is reconstituted by fixing a weighted net in its lower part. Land which is then placed in the middle of a body of water, swimming pool, seaside and to which we want to prevent access from below, everything will depend on the surface of the sports field. For structures offering a mixture of executions, i.e. grid meshes without fillet, and others with fillet, access can be free and the fillet without opening, since one can easily reassemble on the grid through the large openings not fitted with a net.

AMMARRAGE

These playgrounds, in aquatic environments, swimming pool, lake, sea, are moored to ensure their stability. The small modules, used alone, must be ballasted to guarantee their stability, for this, water bags will be attached to the underside of the structure.

REINFORCEMENT STRIP When the structure is likely to be in contact with a ground or rough elements, walls of the swimming pool, it is recommended to place strips of reinforcements of rubber or other material which assembles with the fabric used to make the tubes, and this, in any location that may be worn, on the sides, the bottom, or both. SEAMS

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

5 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 to a strip of fabric with eyelets 10 by means of a rope 11 or double hooks 17, handles 15, seat belts 29, with or without a rudder and brakes 0 with or without motor, becomes a sledge, a bop, to descend, climb the snowy slopes. The brake and rudder system as well as the engine are removable options. The advantages are that the bob is removable, deflates, takes up little space, that one is protected by the tubes. We can sit either in the canvas or on the crosspieces, for more comfort, for example, we can provide, an elastic net to carry luggage fixed along a 5 crosspiece, footrests, fixed, glued on both sides of the tubes. Fig. 15, 16, 17a, 17b,

18a, 18b.

When a canvas is used instead of a net, it is lined with eyelets to allow its fixing.

In summer, it can be used on water. The canvas, bordered with eyelets 7, will be made waterproof in any way, for example: on the periphery a band of adhering rubber is fixed to the tubes. This rubber band is fixed, bonded, thermo welded at the edge of the eyelets, it covers them and comes to be applied, at an angle and going up on the tubes where it is fixed either by suction cups or by a strip of gripping fabric. , and / or either by buttonholes, loops, with rubber buttons mounted on a strip and glued to the J5 tubes. One can add, on the top of the structure, a support for oars.

GOUVERNAIL - BRAKES

It consists of a handle, rudder tube 30 forming an elbow or not, with notches or not, with a handlebar 31, is adjustable in height 33. Its position in height is stopped by a metal rod 35 which passes through the holes 34 provided on the handle 33. FIG. 17a.

This handle 33 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 5 a rod 40, threaded or not which each come s' fit into female supports 41 fixed on either side to the inner part of the bob. Fig. 17a, 17b. The threaded rods are used to receive nuts or fins.

The handle 33, crossed by a metal rod 35 is placed freely on the transverse axis 32 and so as to be able to rotate the assembly.

0 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 33, the upper part of this part will include a platform 57 on which will come to rest the rod 35 threaded into the rudder handle 33. FIG. 23. To avoid excessive floating, a circular cavity, representing the pivoting of the rod 35 is foreseeable either on the transverse axis 32, or on the platform 57 of the support.

FIXING THE BRAKE SYSTEM

On the lower part of the handle 33 is fixed hooks 38, or loops on which are fixed either springs or large elastic bands 37, which are themselves fixed by means of hooks 38, thus connecting the handle 33, to a plate serving as brakes 36. Fig.17a.

Î0 The springs or elastic on the back of the plate 36 are shorter and / or of different traction forces so as to brake according to a progression.

The rear part of the plate 36 is flexible, brushes against the snow, so that by keeping the handlebar 31 straight, the raft in the snow runs straight, moreover a reference point can be fixed at the front, at the junction of the two tubes.

', 5 A little above the part which borders on the snow, a toe clip is fixed 44. The part which follows the flexible part is connected either by a joint, or by a hinge, or it is made of the same thicker materials, 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, 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.

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 a violent shock, the air escapes without making explode the sausages.
