Definitions
- the present invention relates to a structure that can be stiffened by inflation, a manufacturing method and an assembly for the production of a removable shelter.
- Such a structure is in particular intended for the realization of reception tents and for the permanent or temporary cover of sports grounds, swimming pools, tennis courts, motorway rest areas, greenhouses and more generally any place requiring protection against external climatic conditions.
- the object of the invention relates to the technical sector of building , and leisure and more particularly to the field of removable covers for the protection of playgrounds.
- the structures known in the prior art are essentially constituted by removable rigid tubular metal frames supporting fabrics. The establishment of such structures is long and requires a large and qualified workforce.
- American patent 335 54-5 proposes a superstructure made up of longitudinal inflatable chambers.
- This superstructure is not self-supporting and on the contrary requires, at each end, a rigid frame made up of tubular elements. The erection of such a tent is not very simple. As soon as the length of the structure exceeds a few meters, the axial chambers flex, unless they are supported by rigid intermediate reinforcements.
- French patent 2,513 proposes an inflatable superstructure consisting of tubes and spacers. The tubes are made up of two external half-shells containing an inflatable chamber. These shells, by definition rigid, have the function of participating in the rigidity
- the rigid half-shells are connected by bolts passing through lateral bars, which may be deformable.
- the applicant insists on the necessity of a tight connection of the two half-shells, without however specifying the technical solutions envisaged.
- the connection of the intermediate strips and the flanges must be watertight and therefore, careful manufacturing in the factory is necessary.
- the present invention relates to a self-supporting inflatable structure constituted by transverse cylindrical chambers braced by flexible interlayer films. It has the advantage of being modular, that is to say that "room + film” elements can be added or removed without difficulty by the end user.
- the present invention therefore particularly solves the problem of producing a large superstructure, of low cost, which can be put in place by a single person and occupies a reduced volume when it is folded.
- the present invention relates more particularly to a superstructure comprising tubular elements stiffenable by inflation braced with their generatrix opposed by interlayer films, said tubular elements resting on the ground by their two ends and being constituted by a chamber of substantially circular section delimited by an envelope single flexible closed at each end tightly and fitted with an inflation valve.
- the superstructure according to the invention has the advantage of great ease of assembly and of reduced manufacturing cost. It has the essential advantage of a modular size, insofar as the connection of the interlayer films is carried out by simple means, without constraints relating to sealing.
- the rigid tubular elements each consist of substantially cylindrical segments connected at an angle.
- a tubular element When a tubular element is stiffened by inflation, it takes automatically its final shape determined by the angles formed by two successive segments between them. There is, in particular, no risk of formation of wrinkles responsible for premature wear.
- the connection between the tubular elements can be carried out by high-frequency welding, by gluing or by any other known means.
- the inflatable tubular elements comprise along their opposite generatrix connecting strips provided with separable hooking means, such as a zipper.
- any other separable attachment means can be envisaged, in particular laces or hooks cooperating with eyelets, connecting strips known under the name "VELCRO".
- the superstructure according to this variant is completely modular and can be extended or shortened depending on the size of the ground to be covered. Furthermore, it is possible to partially open the superstructure by opening the attachment means bordering an interlayer film and by folding this interlayer film back on itself. This characteristic is particularly important because of the heat generally prevailing inside the superstructures known in the prior art, forming a greenhouse effect. Furthermore, it is thus possible to modify the possible accesses at the discretion of each user.
- the inflatable tubular elements also comprise means for attaching accessories constituted by rigid or semi-rigid support plates fixed to the external walls of the tubular elements by means of a film of slightly larger dimension. upper covering said support plate.
- This film is fixed to the outer wall of the tubular element by means such as gluing or high frequency welding, at at least certain points in a strip surrounding said support plate, the support plate comprising connecting means. such as a threaded bore, screw, or bayonet mount.
- These fixing means do not prevent the tubular elements from being folded back when they are deflated.
- the elements tubular are grouped and when the superstructure is shaped, they allow the attachment of various accessories, such as lights, partitions or interior separation slopes, exterior shrouds.
- connection means are given by way of examples but can, of course, be replaced by any equivalent known in the state of the art for other applications.
- the interlayer films are folded back at their lateral ends to form a hem in which a cord is placed, pressing on the fold line. Regularly spaced eyelets pass through said hem and cooperate with the cord. This hem can be extended by a flap for evacuating rainwater and runoff.
- This embodiment has the advantage of allowing the interlayer films to be fixed to the ground using hooks without the risk of tearing the film.
- the interlayer film is made of transparent plastic, preferably ethylene tetrafluoroethylene.
- the superstructures thus produced allow daylight to pass through and therefore do not require artificial lighting.
- the invention also responds to ecological research insofar as it allows people placed inside the super ⁇ structure to escape the feeling of suffocation resulting from state-of-the-art superstructures and to benefit from from the outside environment.
- At least some of the tubular elements advantageously comprise, at least along their opposite generatrix, a thermoelectric heating tape.
- the thermal radiation emitted by these heating tapes makes it possible to limit the effects of condensation resulting from the interior atmosphere in contact with the cold wall of the superstructure.
- this embodiment makes it possible to avoid fogging and therefore makes it possible to maintain satisfactory transparency.
- this heating tape melts the snow deposited on the structure and thus prevents any risk of deterioration under the weight of it in countries where it snows a lot.
- the tubular elements are made of reinforced polyvinyl chloride.
- This material consists of a fabric impregnated with PVC combining the qualities of waterproofing and tear resistance. It can be produced in transparent or colored form. It can also be treated to safety standards for fire fighting and against ultraviolet and mold.
- the superstructure according to the invention constitutes a hemispherical shelter.
- the tubular elements are connected in their center.
- the present invention also relates to a method of manufacturing a tubular element intended for producing a superstructure of the type comprising tubular elements constituted by cylindrical segments connected at an angle.
- the process consists of:
- This manufacturing process makes it possible to produce a large tubular element corresponding for example to a tent ' of 5 meters high and 10 meters wide, or 8 meters high and 18 meters wide with sufficient reliability to guarantee a seal. at each point.
- This process is, moreover, compatible with high-precision manufacturing with laser cutting tools and / or tools controlled by a computer.
- the joining lines are also covered by an attached strip of flexible material, fixed by means such as gluing or high frequency welding.
- the tubular member This improves the sealing r the most vulnerable places.
- the present invention also constitutes an assembly for the constitution of a removable modular shelter comprising: - a superstructure composed by tubular elements constituted by a simple waterproof envelope braced by flexible intermediate films connected to said tubular elements by separable attachment means and by sections of a shape corresponding to the section of said superstructure, the edges of said sections also being provided with attachment means connectable to the attachment means fixed along the generatrices of the tubular elements,
