Abstract

The pool, made with a supple wall (2) and an inflatable ring (3) round its open edge, has the upper portion (5) of the wall inclined relative to the remainder so that it forms a truncated cone acting as a support for the inflatable ring when the latter is subjected to a downward force. The upper portion (5) of the side wall is made from a curved strip of supple material, and it is inclined at under 70 degrees and preferably 10 - 30 degrees to the horizontal.

Description

La présente invention concerne des perfectionnements apportés aux bassins ouverts formant réservoirs de liquide, notamment aux piscines, du type dit "hors-sol" (c'est-à-dire posé sur le sol), possédant une paroi souple avec un boudin gonflable constituant une ceinture gonflable qui définit l'ouverture dudit bassin.The present invention relates to improvements brought to open basins forming liquid reservoirs, in particular in swimming pools, of the so-called "above-ground" type (ie placed on the ground), having a flexible wall with a flange inflatable constituting an inflatable belt that defines the opening of said basin.

De tels bassins sont actuellement diffusés en tant que piscines de jardin et connaissent un grand succès en raison de leur coût moindre que les piscines hors-sol d'autres types, de leur faible volume à l'état dégonflé/plié, de leur grande facilité de mise en oeuvre (étalement à plat de la toile, gonflage du boudin de ceinture, remplissage d'eau qui fait progressivement monter la ceinture flottante et met progressivement la paroi souple - par exemple en PVC- en tension sous la ceinture flottante).Such basins are currently disseminated as that garden pools and are very successful in because of their lower cost than above ground pools other types, of their small volume in the deflated / folded state, their great ease of implementation (spreading flat on the canvas, inflation of the belt flange, filling with water which gradually increases the floating belt and gradually puts the flexible wall - for example PVC- under tension under the floating belt).

Toutefois, ce type de piscine présente l'inconvénient suivant. Lorsque la ceinture flottante est localement enfondée vers le bas (par exemple une personne s'appuie dessus) en dessous du niveau de l'eau, l'eau s'écoule par cette partie enfoncée formant déversoir : le poids de l'eau en déversement qui surmonte cette partie enfoncée du boudin ainsi que l'effet dynamique de l'eau s'écoulant qui s'exerce sur le sommet de la partie enfoncée du boudin engendrent un effort résultant dirigé vers le bas s'appliquant sur le boudin et supérieur à la poussée d'Archimède s'exerçant de façon ascendante sur la partie immergée du boudin. Il en résulte que le boudin ne peut pas reprendre sa forme initiale et demeure en forme de déversoir par lequel l'eau continue à s'écouler.However, this type of pool has the disadvantage following. When the floating belt is locally folded down (for example a person leans above) below the water level, the water flows through this sunken part forming a weir: the weight of the water in overflow which overcomes this sunken part of the tube as well as the dynamic effect of the flowing water which is exerted on the top of the sunken part of the tube generate a resulting downward force applying to the sausage and greater than the Archimedes thrust exercising from ascending on the submerged part of the tube. It results that the sausage cannot regain its shape initial and remains in the form of a weir through which the water continues to flow.

L'invention a essentiellement pour but de proposer une architecture perfectionnée d'un bassin, notamment une piscine, du type considéré de manière à éliminer l'inconvénient précité, sans qu'il en résulte un surcoût trop important à la fabrication et que par ailleurs le bassin perfectionné conserve les mêmes avantages que les bassins antérieurs.The main purpose of the invention is to provide an improved architecture of a basin, in particular a swimming pool, of the type considered so as to eliminate the inconvenience mentioned above, without resulting in excess cost important to manufacturing and that otherwise the pool improved retains the same benefits as basins earlier.

A cette fin, un bassin, notamment une piscine, tel que mentionné au préambule se caractérise, étant agencé conformément à l'invention, en ce qu'en position d'utilisation dudit bassin la zone périphérique supérieure de la paroi souple jouxtant le susdit boudin est inclinée, par rapport à la partie restante sous-jacente de la paroi, en direction de l'intérieur du bassin.To this end, a basin, in particular a swimming pool, such that mentioned in the preamble is characterized, being arranged in accordance with the invention, in that in the position of use of said pelvis the upper peripheral area of the flexible wall adjoining the above-mentioned tube is inclined, by relative to the remaining underlying part of the wall, in direction of the interior of the basin.

De préférence, ladite zone périphérique supérieure est inclinée d'un angle inférieur à environ 70° par rapport à l'horizontale. Avantageusement, l'inclinaison de la zone périphérique supérieure par rapport à l'horizontale, est comprise entre 0 et environ 30°, de préférence de l'ordre de 10 à 30°.Preferably, said upper peripheral zone is tilted at an angle of less than about 70 ° from horizontally. Advantageously, the inclination of the zone upper peripheral with respect to the horizontal, is between 0 and about 30 °, preferably of the order of 10 to 30 °.

Grâce à cette disposition, la susdite zone périphérique supérieure de la paroi forme un rebord rentrant de forme sensiblement tronconique, sous-jacent au boudin gonflable. Ainsi, la poussée d'Archimède s'exerve positivement non seulement sur boudin pour sa partie au contact du liquide, mais aussi sous ladite partir rentrante de la paroi. Si le boudin est localement déformé vers le bas, il vient en appui sur la partir rentrante sous-jacente qui demeure soumise à la poussée d'Archimède dans les mêmes conditions et avec la même intensité. Dans ces conditions, le poids de l'eau qui se déverse et surmonte localement le boudin déformé et l'effet dynamique de l'eau se déversant qui agit sur le boudin engendrent conjointement un effort résultant qui demeure inférieur à la poussée d'Archimède, laquelle est ici d'intensité accrue. Le boudin reprend alors de lui-même sa forme initiale dès que l'effort déformant cesse de lui être appliqué.Thanks to this arrangement, the aforesaid peripheral zone top of the wall forms a flange substantially frustoconical shape, underlying the sausage inflatable. Thus, Archimedes' thrust is positively preserved not only on sausage for its part in contact with the liquid, but also under the said inward part of the wall. If the flange is locally deformed downwards, it comes to rest on the underlying reentering starting which remains subject to Archimedes' push in the same conditions and with the same intensity. In these conditions, the weight of the water which pours out and locally overcomes the deformed tube and the dynamic effect of the pouring water which acts on the sausage jointly generate an effort resulting which remains lower than Archimedes' thrust, which is here of increased intensity. The sausage then resumes of itself its initial form as soon as the distorting effort ceases to be applied to it.

Parmi les nombreuses solutions techniques pouvant conduire à la formation du rebord rentrant recherché à la partie supérieure de la paroi souple, on peut envisager que la zone périphérique supérieure soit constituée d'une bande souple découpée en arc de cercle et solidarisée, bout-à-bout, sur le pourtour du reste de la paroi souple.Among the many technical solutions that can lead to the formation of the reentrant edge sought at the upper part of the flexible wall, we can consider that the upper peripheral zone consists of a strip flexible cut into an arc and joined, end-to-end, around the rest of the flexible wall.

Toutefois, une autre solution, préférée en raison de la simplicité de réalisation lors de la fabrication du bassin, consiste en ce que la zone périphérique supérieure soit déterminée à partir d'entailles en V pratiquées, à intervalle les unes des autres, sur le pourtour du bord supérieur de la paroi souple et refermées sur elles-mêmes bord contre bord.However, another solution, preferred because of the simplicity of realization during the manufacture of the pelvis, consists of the upper peripheral zone is determined from V-notches made, at interval from each other, around the edge upper part of the flexible wall and closed in on themselves edge to edge.

The invention will be better understood on reading the following detailed description of certain embodiments given solely by way of nonlimiting examples. In this description, reference is made to the appended drawings in which:

A la figure 1 est représenté, en perspective, un bassin 1 ouvert rempli de liquide 4 et formant réservoir de liquide ; en l'occurence il s'agit d'une piscine bien qu'il ne s'agisse pas là de l'application excluvise de l'invention.In Figure 1 is shown, in perspective, a basin 1 open filled with liquid 4 and forming a reservoir for liquid; in this case it is a swimming pool although it this is not the excluded application of the invention.

Le bassin 1 est de type hors-sol, c'est-à-dire posé sur le sol et s'étendant au-dessus du sol. Le bassin 1 est défini par une paroi souple étanche 2, par exemple un film en PVC ou un tissu enduit. Un boudin gonflable 3 constitue une ceinture flottante qui entoure l'ouverture du bassin.Basin 1 is of the above-ground type, i.e. placed on the ground and extending above the ground. Basin 1 is defined by a watertight flexible wall 2, for example a film PVC or coated fabric. An inflatable tube 3 constitutes a floating belt that surrounds the opening of the pelvis.

Pour sa mise en oeuvre, le bassin est déplié et déployé à plat sur le sol ; le boudin 3 est gonflé par exemple à l'air et prend sa forme torique. Puis un liquide (de l'eau par exemple) est versé à l'intérieur de l'espace entouré par le boudin gonflé ; au fur et à mesure que le niveau du liquide s'élève, le boudin, qui flotte, est soulevé en entraínant la paroi souple.For its implementation, the basin is unfolded and deployed flat on the ground; the tube 3 is inflated by example to air and takes its toric form. Then a liquid (water for example) is poured inside the space surrounded by the swollen tube; as the level of the liquid rises, the tube, which floats, is raised by driving the flexible wall.

A l'équilibre, le fond du bassin est plaqué au sol par le poids du liquide le surmontant ; la paroi souple 2 est soumise à la poussée hydrostatique, dirigée radialement, de la masse liquide et à l'effort de traction dirigé vers le haut exercé par le boudin flottant ; et le boudin flottant est soumis à la poussée d'Archimède dirigée vers le haut et l'effort de retenue, dirigé vers le bas, exercé par la paroi souple qu'il soutient.At equilibrium, the bottom of the basin is placed on the ground by the weight of the liquid overcoming it; the flexible wall 2 is subjected to hydrostatic thrust, directed radially, of the liquid mass and the tensile force directed towards the high exerted by the floating rod; and the floating sausage is subject to Archimedes' upward thrust and the downward directed restraint force exerted by the wall flexible that it supports.

Conformément à l'invention, la zone périphérique supérieure 5 de la paroi souple 2, qui jouxte immédiatement le boudin 3, est inclinée fortement, par rapport à la partie sous-jacente de la paroi 2, en direction de l'intérieur du bassin. Cette disposition est particulièrement mieux visible sur la figure 2 qui montre une coupe transversale, à échelle agrandie, du boudin 3 et de la zone adjacente de la paroi 2 du bassin de la figure 2. L'inclinaison de ladite zone périphérique 5 est inférieure à environ 70° par rapport à l'horizontale, en étant avantageusement comprise entre 0 et environ 30°, et de préférence de l'ordre de 10 à 30°.According to the invention, the peripheral zone upper 5 of the flexible wall 2, which immediately adjoins the flange 3, is inclined sharply, relative to the part underlying the wall 2, towards the interior of the pool. This provision is particularly better visible in Figure 2 which shows a cross section, to scale enlarged, the rod 3 and the adjacent area of the wall 2 of the basin of FIG. 2. The inclination of said zone device 5 is less than about 70 ° from the horizontal, being advantageously between 0 and about 30 °, and preferably of the order of 10 to 30 °.

Grâce à cet agencement, non seulement la fraction immergée du boudin 2 est soumise à la poussée d'archimède, mais la zone périphérique inclinée 5 l'est également (flèche 7). On accroít ainsi la surface soumise à la poussée d'Archimède.Thanks to this arrangement, not only the fraction submerged from the rod 2 is subjected to the Archimedes push, but the inclined peripheral zone 5 also is (arrow 7). This increases the surface subjected to the thrust Archimedes.

Lorsque le bord du bassin est soumis localement à un effort dirigé vers le bas (par exemple une personne prenant appui sur le boudin entourant la piscine), dans un bassin agencé traditionnellement la partie de la paroi jouxtant le boudin 3 se plisse sans jouer de rôle fonctionnel : le poids de l'eau se déversant par dessus le boudin conjointement avec l'effort dynamique de l'eau qui s'écoule engendrent sur le boudin un effort résultant dirigé vers le bas qui est supérieur à la poussée d'Archimède s'exerçant sur la fraction immergée du boudin : lorsque l'effort déformant initial cesse d'être appliqué sur le boudin, celui-ci ne peut donc pas reprendre sa forme initiale et le déversement de l'eau se poursuit.When the edge of the basin is locally subjected to a downward effort (e.g. a person taking support on the sausage surrounding the swimming pool), in a basin traditionally arranged the part of the wall adjoining the sausage 3 folds without playing a functional role: the weight water pouring over the tube jointly with the dynamic effort of the flowing water generate on the sausage a resulting effort directed downward which is greater than the Archimedes thrust exerted on the submerged fraction of the rod: when the deforming effort initial ceases to be applied to the tube, it does not therefore cannot return to its original shape and the spill water continues.

Par contre, dans un bassin agencé conformément à l'invention, l'accroissement de la surface soumise à la poussée d'Archimède fait que la force de poussée ascendante, accrue, est supérieure à l'effort résultant précité (poids de l'eau se déversant et effort dynamique de l'eau qui s'écoule). Dès que l'effort déformant initial (flèche 6 sur la fig. 3) cesse d'être appliqué sur le boudin, la poussée d'Archimède (flèches 7) ramène le boudin dans sa position initiale, et l'écoulement d'eau est interrompu.On the other hand, in a basin arranged in accordance with the invention, the increase in the surface subjected to the Archimedes' push causes the upward pushing force, increased, is greater than the aforementioned resulting effort (weight pouring water and dynamic water stress which flows). As soon as the initial deforming force (arrow 6 on fig. 3) ceases to be applied to the flange, the thrust Archimedes (arrows 7) brings the sausage back to its position initial, and the water flow is interrupted.

En pratique, compte tenu des efforts s'exerçant sur la paroi 2, un bassin du genre considéré est, pour être stable, de forme approximativement circulaire, et la zone 5 est alors de forme générale approximativement tronconique de révolution.In practice, taking into account the efforts exerted on wall 2, a basin of the kind considered is, to be stable, approximately circular in shape, and zone 5 is then of roughly frustoconical general form of revolution.

Pour conférer à la paroi souple 2 la forme requise périphériquement au voisinage du boudin 3, différentes solutions techniques peuvent être envisagées.To give flexible wall 2 the required shape peripherally in the vicinity of the flange 3, different technical solutions can be considered.

On peut, comme illustré très schématiquement à la figure 4, ceinturer la zone supérieure de la paroi 2 immédiatement adjacente au boudin 3 avec un lien annulaire externe 8 (sangle, corde, etc.) qui s'étend périphériquement avec un diamètre sensiblement plus faible que le diamètre de la liaison paroi-boudin.We can, as illustrated very schematically in the figure 4, belt the upper area of the wall 2 immediately adjacent to flange 3 with an annular link outer 8 (strap, rope, etc.) that extends peripherally with a diameter significantly smaller than the diameter of the wall-rod connection.

Une autre solution peut consister, comme illustré à la figure 5, à rapporter, par exemple par soudure, sur le bord supérieur 9 de la paroi 2, une bande souple 10 de forme annulaire ouverte (en arc de cercle) qui, une fois fermée sur elle-même et solidarisée à la paroi souple 2, prend une forme tronconique et constitue ainsi la susdite zone 5. Le boudin 3 est alors solidarisé au bord libre 11 de cette bande (sur la fig. 5, le boudin 3 n'a pas été représenté pour faciliter la lecture).Another solution may be, as illustrated in Figure 5, to report, for example by welding, on the upper edge 9 of wall 2, a flexible strip 10 of shape open annular (in an arc) which, when closed on itself and secured to the flexible wall 2, takes a tapered shape and thus constitutes the above-mentioned zone 5. The sausage 3 is then secured to the free edge 11 of this strip (in fig. 5, the flange 3 has not been shown for easier reading).

Une autre solution peut consister, comme illustré aux figures 6A et 6B, à découper dans le bord supérieur 12 de la paroi souple 2 des entailles 13 en V espacées les unes des autres, dont les bords sont ensuite rapprochés et soudés, par exemple avec adjonction d'une pièce de renfort 14. Cet agencement entraíne une réduction du diamètre de la zone 5 adjacente au bord 12 et donc à la formation d'une zone 5 de forme tronconique inclinée vers l'intérieur par rapport à la partie restante de la paroi 2. Cette solution est très facile à mettre en oeuvre en pratique car elle permet de travailler sur des pièces de matière souple qui sont planes et à ce titre elle est actuellement préférée : la paroi souple 2 du bassin est en pratique constituée d'un ensemble de panneaux de formes trapézoïdales curvilignes découpés à plat, puis assemblés par leur base à un fond plat circulaire. La découpe des entailles et le rapprochement de leurs bords peut alors se faire à plat sur les panneaux initiaux.Another solution may be, as illustrated in Figures 6A and 6B, to be cut from the upper edge 12 of the flexible wall 2 of the V-shaped notches 13 spaced apart others, whose edges are then brought together and welded, for example with the addition of a reinforcement piece 14. This arrangement causes a reduction in the diameter of the zone 5 adjacent to edge 12 and therefore to the formation of a zone 5 of frustoconical shape inclined inwards by compared to the remaining part of wall 2. This solution is very easy to implement in practice because it allows you to work on pieces of flexible material which are flat and as such it is currently preferred: the flexible wall 2 of the basin is in practice made up of a set of curved trapezoidal shaped panels cut flat, then assembled by their base to a flat bottom circular. Cutting the notches and bringing together their edges can then be made flat on the panels initials.

Comme il va de soi et comme il résulte déjà de ce qui précède, l'invention ne se limite nullement à ceux de ses modes d'application et de réalisation qui ont été plus particulièrement envisagés ; elle en embrasse au contraire toutes les variantes.As it goes without saying and as it already results from this above, the invention is in no way limited to those of its modes of application and embodiments which have been more particularly envisaged; on the contrary, she embraces all variants.
