Definitions

  • This invention relates to inflatable structure(s) formed by construction elements that can be used to dimension a base module.
  • Inflatable structure(s) made up of tubes between which wide openings are left free.
  • the surface area of these structures is created by increasing the number of elements constituting its members, crosses, corners, T-bars and bends, thereby creating a base module which can be used on its own.
  • the module thus formed comprises, on the inner periphery of at least one of these openings or even all of these openings, a strip of fabric associated with attachment means, said strip of fabric being fixed to the tube at the height at which netting, canvas or accessories are to be fixed.
  • this surface may have a bridge added to it, on which it is possible to walk, this bridge being reproduced on any number of faces of the base module where it is desirable to increase the number of wide openings.
  • Document FR 2 505 914 discloses a rigid frame around the edge of a swimming pool, over which netting is stretched to cover the entire swimming pool, and a float causes the frame to rise to the surface.
  • the rigidity constitutes a problem because a frame of this design bends when subjected to load.
  • Document DE32 10590 A1 discloses a life raft made up of units attached by hooks. It is not possible to walk on the joining point between two surfaces because of the way the surfaces are joined.
  • Document WO02/079027 discloses a reversible life raft consisting of a single unit.
  • aquatic trampolines For applications involving sports grounds, the prior art discloses aquatic trampolines and these trampolines generally comprise an air chamber with a centre opening over which is placed a canvas, on which it is possible to jump and rebound because springs or elastic ropes or both are used as the fixing systems and mounted on a rigid tube, as is the case described in documents U.S. Pat. Nos. 5,810,695, 6,508,682. These are essentially designed to enable jumping on the single canvas or belt, and rapid mounting and dismantling of the rebound canvas so as to allow other activities is not envisaged.
  • Document U.S. Pat. No. 6,223,673 discloses a trampoline to which an access ramp and two joined tubes can be fitted to form a slide.
  • This system is designed so that it is possible to jump on the belt and the access ramp is used for mounting and dismounting the trampoline and the slide is used to get down from it.
  • These trampolines are limited in terms of the possible activities for which they can be used and are not designed for sports other than trampolining or games which involve getting on and off the trampoline.
  • the inflatable structure described in this instance it is the structure itself which reacts, whereas in the case of standard trampolines the structure is rendered rigid by tubing and it is the tension on the elastic ropes and/or springs which causes the rebound.
  • This inflatable structure also enables a base surface for multiple games to be created, wherein rapid mounting and dismantling of netting, canvas and accessories is possible, which surface can be added to on each of its sides by virtue of a bridge.
  • the aim of the invention is therefore to provide a polyvalent inflatable structure which can remedy these drawbacks and disadvantages in each field of application.
  • the invention is defined by the combination of features of claim 1 and the subsequent claims.
  • FIG. 1 illustrates an inflatable structure 1 , in the shape of a cross 2 with corners, in this particular case right-angled corners 3 , T-bars 4 and openings 5 , with handles 15 and an inflation/deflation valve 19 .

  • the non-welded or non-bonded part 33 is separated into two parts and opened out and can then be fixed or bonded onto the tube 8 as in FIG. 2 .
  • a protective strip of fabric 49 is bonded onto this strip of fabric 10 at the fixing means, and is left free and covers the fixing means and ropes.
  • the strip of fabric 10 will be reinforced for example by at least one seam 65 at the fixing means, FIG.
  • the seam is formed either on the strip of fabric 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 netting or canvas by some attachment means for example. This applies to any type of structure, swimming pool, life raft, sports ground, toboggan.
  • the strip of fabric 10 will be covered on its upper and lower part by a strip of fabric bonded at its edge to the tube and covering the strip of fabric 10 over a few centimeters.
  • This strip of fabric 10 with eyelets 7 or fixing means may be used both around the inner periphery of the structure for accessories such as foot rests for example for the netting or canvas 18 and on the exterior, below the structure, as a means of fitting the weighted netting 47 using ropes or hooks.
