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
• 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.
• 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.
• 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.
• FIG. 1 is a perspective view of the superstructure according to the invention
• FIG. 2 is a side section view of a tubular element connected to an interlayer film
• FIG. 5 - Figure 4 is a front view of a tubular element.
• the tubular elements are made of a tear-resistant plastic material, for example reinforced polyvinyl chloride constituted by a fabric of synthetic fibers impregnated with PVC.
• 2 shows a sectional view along the section of a tubular element (1) connected to an interlayer film (2).
• the tubular element (1) consists of a chamber (9) constituted by a simple envelope (10).
• the simple envelope '(10) consists of a film wound on itself and connected by high frequency welding or gluing.
• An attached strip (11) of the same material or an equivalent material is glued or welded to the junction zone (12). This attached strip (11) improves the tightness of the tubular element (1).
• Two connecting strips (13) of the same material or of equivalent material are glued or welded on r casing (10) along their opposite generatrix.
