FR2588823A1 - Domes (or parachute canopies) and double casings which are themselves inflatable - Google Patents

Abstract

Casings and domes (or parachute canopies) characterised in that this time they are constituted not simply by a single layer but by two layers, which can be inflated in the space between them. Articles, inter alia, for ballooning, parachuting (or paragliding) and toys.

Description

 The invention is a SINGLE GENERAL INVENTIVE CONCEPT which relates, inter alia, to Domes (or Canopies) for Parachutes (or Paraplanes) and Envelopes for Aerostats.

 Currently, in a completely different field, we already know the technique of pneumatic mattresses which generally consist of two waterproof and waterproof relatively flexible and elastic layers, layers juxtaposed and fixed on their outer cradles to thus constitute a pneumatic chamber divided internally by partitions in number and of variable shape, the most common of which are longitudinal partitions intended to delimit parallel air chambers which, once inflated, form as many tubes, with one or more genflage orifices and their corresponding plug (s).

 In I '@ ccurence, it is a question of adapting and perfecting the known technique of air mattresses, to the manufacture, among other things, of envelopes for aerostats and of cups (or canopies) for parachutes (or paraplanes) but this DOUBLE feis instead of a single layer, in suitable materials of course.

 In addition, or in place of one or two isothermal layers as the case may be, it is also possible to cover or include a coating or a product capable of capturing the heat of the sun's rays inside. toupee (or canopy) or the DOUBLE envelope itself, the air of which would thus be naturally heated or warmed there.

The three main ir @ fustable NEWS of this general inventive concept are
1) Hitherto, conventional air mattresses were neither provided for nor made up of materials making it possible to contain and keep hot air and especially gases do not rise up and do not rise in the atmosphere , and even did not slow down or slow down as a whole a fall of a body in the atmosphere.

2) The dome of the parachutes (on paraplanes) were composed of a simple wing in a single non-pneumatic layer as prevn here, which now allows, consequently, an improved lift for better gliding and even possibly practicing a kind of " Free flight"
30) The traditional envelopes of the estates were composed and are composed of a single single layer and not DOUBLE, and one filled the interior of the whole of the structure of this simple envelope, and, not as currently planned the DOUBLE SHEET inflatable between the two component layers of the envelope.

The obvious essential advantages which flow from this general inventive concept are t
1) Increased safety as a result of two component layers or place of one, and of the independence of the partitions between them possibly, in the event, for example of a tear of one of the two component layers or of one partitions.

 Of course, a set of a dome (or wing) or of a double envelope can be inflated into a base f @ times by a single orifice (valid rather for the domes or wings of parachutes and / or paraplanes). or it can be provided there for several inflation orifices (and deflation) in the case of several independent partitions one or the other (rather valid for / the double envelopes of aerostats for more safety and maneuverability), in dehers and in addition possibly to soup, with their or their caps.

 The interior partitions between the two layers of a dome (or canopy) or of a double envelope yes are intended, once gelled, to delimit parallel air chambers, form as many sausages / crescents (figure 1) or sausages ( figure 2) can be in any direction: height, width, logger, even oblique @ pourqu @ i not.

 Finally, it goes without saying that in this case it is possible to use all the improvements already known and / or patented concerning pneumatic mattresses, the domes (or canopies) of parachutes or parasols and the envelopes of aerostats, and , that one can even bring to the present general inventive concept @ @ modifications of details in the grid of technical equivalences, without thereby departing from the framework of the current general inventive concept, even when # a miniature and / or toy reproduction.

Claims (7)

 1. Structure, inter alia, of envelope for aerostat or dome (or canopy) of parachute or paraplane characterized in that  - the envelope or the dome (or wing) is made up no longer of a single but of DE UX waterproof and impermeable layers juxtaposed and fixed on their edges to thus constitute a pneumatic chamber between the two component layers of the same envelope or cup (or veil).  2. Structure according to Claim 1, characterized in that one or both of the constituent layers are replaced or added in addition by a layer capable of capturing and retaining the heat of the sun's rays.  3. Structure according to Claim I or 2, characterized in that the pneumatic chamber is internally divided by one or more cleisonnements in number and of variable forms.  4. Structure according to claim n or 2 or 3 characterized in that the had internal partitions feels intended i to delimit air chambers which, once inflated, close as many tubes (figure 2) or tubes / croissants (figure 1), independent or not between them.  5. Structure according to Claim I or 2 on 3 on 4 characterized in that a part of the surface is not pneumatic and has or does not have a valve.  6. Structure according to Claim 1 on 2 or 3 or 4 or 3 characterized in that it comprises one or more inflation orifices and one or more plugs.  7. Structure according to Claim 1, on 2 ci 3 had 4 or 5 or 6 characterized in that it is miniature toy stake.
