Description

La présente invention concerne le domaine des dispositifs servant à l'évacuation de l'eau de pluie, en particulier des toits des bâtiments et des terrasses.The present invention relates to the field of devices for the evacuation of rainwater, in particular roofs of buildings and terraces.

Généralement, les dalles plates de toits et les terrasses entourées de rebords présentent des trous d'écoulement de l'eau de pluie qui est dirigée vers un réseau d'évacuation par des canalisations.Generally, flat roof slabs and terraces surrounded by rims have rainwater drainage holes which are directed to a drainage network through pipes.

Pour éviter que le réseau d'évacuation ne soit engorgé et ne déborde, il est connu d'équiper les toits et les terrasses de plots cylindriques verticaux en saillie, généralement en tôle, qui entourent les trous d'écoulement et qui présentent des ouvertures traversantes de telle sorte qu'il se produit une limitation du débit de l'eau évacuée.In order to prevent the drainage network from being clogged and overflowing, it is known to equip the roofs and terraces with vertical cylindrical studs, generally made of sheet metal, which surround the drainage holes and which have through openings such that there is a limitation of the flow of the discharged water.

De tels plots sont fabriqués spécifiquement pour chaque toit ou terrasse, en adaptant les dimensions des ouvertures traversantes principalement en fonction de la surface du toit ou de la terrasse à équiper et de la pluviométrie du lieu où les plots se trouvent. Ainsi, les fabricants doivent disposer d'une gamme de plots permettant de répondre aux besoins, ce qui entraîne une gestion complexe et coûteuse des fabrications, des stocks et des réseaux de distribution commerciale.Such studs are manufactured specifically for each roof or terrace, adapting the dimensions of the through openings mainly depending on the roof surface or terrace to be equipped and the rainfall of the place where the studs are located. Thus, manufacturers must have a range of pads to meet the needs, resulting in complex and expensive management of manufacturing, inventory and commercial distribution networks.

Par ailleurs, les documents DE 18 06 527 , US 3 517 813 , US 4 400 272 , CA 2 409 056 et FR 762 406 décrivent des dispositifs d'écoulement d'eau comprenant des parois fixes trouées et des parois mobiles adjacentes aux parois fixes et éventuellement trouées, de façon à permettre un réglage du débit de l'écoulement d'eau. Cependant, ces dispositifs connus sont complexes et difficiles à construire et à mettre en place.In addition, the documents DE 18 06 527 , US 3,517,813 , US 4,400,272 , CA 2,409,056 and FR 762 406 describe water flow devices comprising perforated fixed walls and moving walls adjacent to the fixed and possibly perforated walls, so as to allow adjustment of the flow rate of the water flow.

Selon une variante de réalisation illustrée sur les figures 1 à 5, un dispositif d'évacuation 1 d'eau de pluie, par exemple en tôle galvanisée, comprend une platine horizontale 2, par exemple carrée, qui présente un trou central circulaire 3, et un conduit vertical cylindrique inférieur 4 dont le bord supérieur, replié vers l'extérieur, est fixé sur le bord du trou 3, par exemple par un cordon de soudure ou soudé par points, par exemple de façon étanche.According to an embodiment variant illustrated on the Figures 1 to 5 , a device 1 for evacuating rainwater, for example galvanized sheet metal, comprises a horizontal plate 2, for example square, which has a circular central hole 3, and a lower cylindrical vertical duct 4 whose upper edge, folded outwardly, is fixed on the edge of the hole 3, for example by a weld seam or spot welded, for example tightly.

Le dispositif d'évacuation 1 comprend en outre une paroi verticale tubulaire fixe 5, par exemple cylindrique, s'étendant vers le haut, dont le diamètre est plus grand que le diamètre du conduit 4 et dont le bord inférieur est fixé sur la face supérieure de la platine horizontale 2, concentriquement au conduit 4, par exemple par un cordon de soudure intérieur. Le bord inférieur de la paroi verticale fixe 5 est situé entre le passage déterminé par le conduit inférieur 4 et le bord périphérique de la platine 2.The evacuation device 1 further comprises a fixed cylindrical vertical wall 5, for example cylindrical, extending upwards, whose diameter is greater than the diameter of the duct 4 and whose lower edge is fixed on the upper face. of the horizontal plate 2, concentrically to the conduit 4, for example by an internal weld bead. The lower edge of the fixed vertical wall 5 is located between the passage determined by the lower duct 4 and the peripheral edge of the plate 2.

La paroi verticale fixe 5 présente une pluralité d'ouvertures traversantes 6, qui sont par exemple de formes rectangulaires étendues vers le haut, de sections identiques et régulièrement réparties périphériquement.The fixed vertical wall 5 has a plurality of through openings 6, which are for example of rectangular shapes extended upwards, of identical sections and regularly distributed peripherally.

Le dispositif d'évacuation 1 comprend en outre un obturateur mobile 7 qui, selon l'exemple représenté, comprend une paroi verticale tubulaire 8, cylindrique, placée autour de la paroi verticale fixe 5, de façon adjacente, et en appui sur la face supérieure de la platine horizontale 2, de façon à être mobile en rotation par rapport à la paroi verticale fixe 5. Dans une variante, la paroi verticale mobile 8 pourrait être disposée à l'intérieur de la paroi verticale fixe 5, le cordon de soudure de la paroi verticale fixe 5 sur la platine 2 pouvant alors être à l'extérieur.The evacuation device 1 further comprises a movable shutter 7 which, according to the example shown, comprises a cylindrical vertical tubular wall 8, placed around the fixed vertical wall 5, adjacent and bearing on the upper face. of the horizontal plate 2, so as to be rotatable relative to the fixed vertical wall 5. In a variant, the mobile vertical wall 8 could be arranged inside the fixed vertical wall 5, the cord of welding of the fixed vertical wall 5 on the plate 2 can then be outside.

La paroi verticale mobile 8, dont la hauteur correspond approximativement à celle de la paroi verticale fixe 5, présente une pluralité d'ouvertures traversantes 9, qui sont par exemple de formes rectangulaires étendues vers le haut, de sections identiques et régulièrement réparties périphériquement.The movable vertical wall 8, the height of which corresponds approximately to that of the fixed vertical wall 5, has a plurality of through-openings 9, which are, for example, rectangular shapes extending upwards, of identical sections and regularly distributed peripherally.

Les ouvertures traversantes 9 de la paroi verticale mobile 8 et les ouvertures traversantes 6 de la paroi verticale fixe 5 sont approximativement de mêmes dimensions.The through openings 9 of the movable vertical wall 8 and the through openings 6 of the fixed vertical wall 5 are of approximately the same dimensions.

La paroi verticale mobile 8 peut être déplacée en rotation par rapport à la paroi verticale fixe 5 qui la guide, de façon à créer une pluralité de passages réglables d'écoulement d'eau 10, dont les sections sont réglables, lorsque les ouvertures traversantes 9 de la paroi verticale mobile 8 et les ouvertures traversantes 6 de la paroi verticale fixe 5 sont au moins en partie en coïncidence.The movable vertical wall 8 can be displaced in rotation with respect to the fixed vertical wall 5 which guides it, so as to create a plurality of adjustable water flow passages 10, whose sections are adjustable, when the through openings 9 of the movable vertical wall 8 and the through openings 6 of the fixed vertical wall 5 are at least partly in coincidence.

En vue d'une indexation et du maintien de la paroi verticale mobile 8 par rapport à la paroi verticale fixe 5, en différentes positions de réglage, le bord supérieur de la paroi verticale mobile 8 peut présenter, comme illustré notamment sur les figures 1 et 3, une pluralité d'encoches 11 décalées périphériquement et le bord supérieur de la paroi verticale fixe 5 peut présenter, comme illustré notamment sur les figures 1 et 4, une languette rabattable 12 pouvant être engagée dans respectivement les encoches d'indexation 11.With a view to indexing and maintaining the movable vertical wall 8 with respect to the fixed vertical wall 5, in different adjustment positions, the upper edge of the movable vertical wall 8 may have, as illustrated in particular on the figures 1 and 3 , a plurality of notches 11 offset peripherally and the upper edge of the fixed vertical wall 5 may have, as illustrated in particular on the figures 1 and 4 , a folding tongue 12 which can be engaged in the indexing notches 11, respectively.

A titre d'autre moyen d'indexation, on pourrait prévoir des repères sur les parois fixes et mobiles 5 et 8 et ces parois, placées en position réglée, pourraient être reliées par des vis ou des rivets les traversants.As another means of indexing, one could provide markings on the fixed and movable walls 5 and 8 and these walls, placed in the adjusted position, could be connected by screws or rivets through them.

Par exemple, les ouvertures traversantes 6 de la paroi verticale fixe 5 peuvent être au nombre de cinq, les ouvertures traversantes 9 de la paroi verticale mobile 8 peuvent être au nombre de dix et les encoches d'indexation peuvent être au nombre de dix, de telle sorte qu'il existe dix positions de réglage correspondant à dix largeurs différentes des passages d'écoulement réglables 10, déterminées dix sections différentes des passages réglables 10 d'écoulement d'eau.For example, the through openings 6 of the fixed vertical wall 5 may be five in number, the through openings 9 of the movable vertical wall 8 may be ten in number and the indexing notches may be ten in number. so that there are ten adjustment positions corresponding to ten widths different from the adjustable flow passages 10, determined ten different sections of the adjustable water flow passages.

Comme illustré sur la figure 5, le dispositif d'évacuation 1 peut être installé sur une paroi plate ou dalle de réception 13 d'un toit 14, ou d'une terrasse, par exemple recouvert d'une couche extérieure d'étanchéité 15, par exemple en une matière bitumeuse ou autre matière étanche, et présentant un trou vertical 16 dans lequel est installé un conduit vertical d'évacuation 17 de l'eau de pluie, présentant une collerette d'extrémité supérieure 17a, annulaire, noyée dans la couche d'étanchéité 15.As illustrated on the figure 5 , the evacuation device 1 can be installed on a flat wall or reception slab 13 of a roof 14, or a terrace, for example covered with an outer sealing layer 15, for example of a bituminous material or other waterproof material, and having a vertical hole 16 in which is installed a vertical discharge pipe 17 of the rainwater, having an upper end collar 17a, annular, embedded in the sealing layer 15.

Pour cela, on engage le conduit vertical inférieur 4 dans le conduit d'évacuation 17 jusqu'à placer la face inférieure de la platine 2 sur la couche extérieure d'étanchéité 15 du toit 14. Puis, on place un morceau de couche d'étanchéité 18, par exemple aussi en une matière bitumée, sur la périphérie de la face supérieure de la platine 2 et sur la couche d'étanchéité 15, que l'on fixe par exemple par chauffage ou autre moyen de collage. Le dispositif d'évacuation 1 est alors fixé. Des moyens complémentaires de fixation ou d'autres moyens de fixation pourraient être utilisés.For this, the lower vertical duct 4 is engaged in the discharge duct 17 until the lower face of the plate 2 is placed on the outer sealing layer 15 of the roof 14. Then, a piece of sealing 18, for example also in a bitumen material, on the periphery of the upper face of the plate 2 and on the sealing layer 15, which is fixed for example by heating or other means of bonding. The evacuation device 1 is then fixed. Additional fastening means or other fastening means could be used.

Puis, on règle, à la main, la position en rotation de la paroi verticale mobile 8 par rapport à la paroi verticale fixe 5, dans une position de réglage préalablement déterminée, notamment en fonction de la surface du toit 14, ou de la terrasse, à équiper, de la pluviométrie du lieu et du nombre de dispositifs d'évacuation prévus sur le toit, ou toutes autres contraintes réglementaires, de façon à créer des passages d'écoulement 10 calibrés de dimensions déterminées. Puis, on rabat la languette rabattable 12 dans l'encoche d'indexation 11 correspondante.Then, by hand, the rotational position of the movable vertical wall 8 with respect to the fixed vertical wall 5 is adjusted in a predetermined adjustment position, in particular as a function of the surface of the roof 14, or of the terrace , to equip, the rainfall of the place and the number of evacuation devices provided on the roof, or any other regulatory constraints, so as to create calibrated flow passages 10 of determined dimensions. Then, fold down the folding tongue 12 in the indexing notch 11 corresponding.

Ainsi, l'eau de pluie récupérée sur le toit 14 peut s'écouler au travers des passages calibrés d'écoulement 10, de l'extérieur vers l'intérieur des parois 5 et 8, selon un débit calibré, et être évacuée par le conduit vertical 4 puis par le conduit d'évacuation 17.Thus, the rainwater recovered on the roof 14 can flow through the calibrated flow passages 10, from the outside to the inside of the walls 5 and 8, at a calibrated flow rate, and be evacuated by the vertical duct 4 and then through the exhaust duct 17.

On peut noter que la valeur réelle du débit dépend de la hauteur du niveau de l'eau sur le toit 14 par rapport aux passages d'écoulement 10 et que le débit maximum, pour les sections choisies des passages d'écoulement 10, est approximativement atteint lorsque la hauteur du niveau de l'eau est au niveau ou au-dessus des bords supérieurs des passages d'écoulement 10. De plus, par sécurité, lorsque le niveau de l'eau atteint ou passe au-dessus de la hauteur des parois 5 et 8, l'eau se déverse directement à l'intérieur de ces dernières vers l'évacuation 17.It may be noted that the actual value of the flow rate depends on the height of the water level on the roof 14 with respect to the flow passages 10 and the maximum flow rate for the selected sections of the passages. 10, is approximately reached when the height of the water level is at or above the upper edges of the flow passages 10. In addition, for safety, when the water level reaches or passes above the height of the walls 5 and 8, the water flows directly into the latter towards the evacuation 17.

Il résulte de ce qui précède que le dispositif d'évacuation 1 constitue un limiteur de débit réglable, pouvant être installé sur des toits ou des terrasses de surfaces différentes situés dans des lieux de pluviométries différentes, la paroi verticale fixe 5 avec ses ouvertures 6 et la paroi verticale mobile 8 avec ses ouvertures 9 constituant un moyen de réglage du débit.It follows from the foregoing that the evacuation device 1 constitutes an adjustable flow restrictor, which can be installed on roofs or terraces of different surfaces located in different pluviometries, the fixed vertical wall 5 with its openings 6 and the movable vertical wall 8 with its openings 9 constituting a flow control means.

Selon une variante de réalisation, le dispositif d'évacuation 1 pourrait être équipé, préalablement à son installation, d'une membrane souple annulaire collée sur la face inférieure de la platine 2 et dépassant à la périphérie de cette dernière et/ou d'une membrane souple en forme annulaire collée sur la face supérieure de la platine 2 et dépassant à la périphérie de cette dernière, s'intégrant sur ou dans la couche extérieure d'étanchéité 15 du toit 14.According to an alternative embodiment, the evacuation device 1 could be equipped, prior to its installation, with an annular flexible membrane bonded to the lower face of the plate 2 and protruding at the periphery of the latter and / or a flexible membrane shaped annular glued to the upper face of the plate 2 and protruding at the periphery thereof, integrating on or in the outer sealing layer 15 of the roof 14.

Selon une variante de réalisation illustrée sur les figures 6 et 7, un dispositif d'évacuation 20 d'eau de pluie comprend, une platine horizontale 21 qui présente un bord périphérique circulaire et un trou central 22 dont le bord est sur et est accouplé à l'extrémité supérieure d'un conduit vertical cylindrique inférieure 23 par des moyens que l'on décrira plus loin.According to an embodiment variant illustrated on the figures 6 and 7 a rainwater discharge device 20 comprises a horizontal plate 21 which has a circular peripheral edge and a central hole 22 whose edge is on and is coupled to the upper end of a lower cylindrical vertical conduit 23 by means that will be described later.

De façon équivalente au dispositif d'évacuation 1, le dispositif d'évacuation 20 comprend une paroi verticale fixe tubulaire 24, cylindrique, dont le bord inférieure est fixé sur la platine 22, concentriquement, par exemple par un cordon de soudure intérieur.Equivalently with the evacuation device 1, the evacuation device 20 comprises a cylindrical fixed vertical tubular wall 24, whose lower edge is fixed on the plate 22, concentrically, for example by an internal weld bead.

Le dispositif d'évacuation 20 comprend en outre une paroi verticale mobile tubulaire 25, cylindrique, placée autour de la paroi verticale fixe 24, de façon adjacente, et en appui sur la platine 22.The evacuation device 20 further comprises a cylindrical movable vertical wall 25, placed around the fixed vertical wall 24, adjacent and bearing on the plate 22.

Pour constituer un moyen de réglage de débit, la paroi verticale fixe 24 et la paroi verticale mobile 25 peuvent être configurées comme la paroi verticale fixe 5 et la paroi verticale mobile 8 du dispositif d'évacuation 1 et présentent respectivement une pluralité d'ouvertures 26 et une pluralité d'ouvertures 27 permettant de créer des passages d'écoulement 28 réglables par rotation de la paroi verticale mobile 25 par rapport à la paroi verticale fixe 24, ainsi que, en vue d'une indexation, une pluralité d'encoches 29 et une languette rabattable 30.To constitute a flow control means, the fixed vertical wall 24 and the movable vertical wall 25 can be configured as the fixed vertical wall 5 and the movable vertical wall 8 of the evacuation device 1 and respectively have a plurality of openings 26 and a plurality of openings 27 for creating flow passages 28 adjustable by rotation of the movable vertical wall 25 relative to the fixed vertical wall 24, as well as, for indexing purposes, a plurality of notches 29 and a folding tongue 30.

Le dispositif d'évacuation 20 comprend en outre une membrane souple horizontale 31, par exemple en une matière d'étanchéité, notamment en une matière bitumeuse, qui s'étend sous la platine 21 et est accolée à cette dernière et s'étend au-delà du bord périphérique de la platine 21. La membrane souple 31 présente un passage central dont le bord 32, cylindrique, est accolé à la partie extérieure d'extrémité supérieure du conduit 23.The evacuation device 20 further comprises a horizontal flexible membrane 31, for example a sealing material, especially a bituminous material, which extends under the plate 21 and is contiguous thereto and extends beyond Beyond the peripheral edge of the plate 21. The flexible membrane 31 has a central passage whose cylindrical edge 32 is attached to the outer end of the upper portion of the conduit 23.

Pour accoupler la platine 21 et la membrane souple 31 sur l'extrémité supérieure du conduit 23, par exemple de façon étanche, sont prévues une bague extérieure 33 enserrant le bord cylindrique 32 de la membrane souple 31 contre la partie extérieure d'extrémité du conduit 23 et une bague intérieure 34 appliquée contre la partie intérieure d'extrémité du conduit 23. En outre, la bague extérieure 33 et la bague intérieure 34 présentent des collerettes périphériques 35 et 35 qui prennent entre elles la partie horizontale de la platine adjacente à son passage central 22 et la partie horizontale de la membrane 31 adjacente à son bord cylindrique 32.To couple the plate 21 and the flexible membrane 31 on the upper end of the duct 23, for example in a sealed manner, are provided an outer ring 33 enclosing the cylindrical edge 32 of the flexible membrane 31 against the outer end portion of the duct 23 and an inner ring 34 applied against the inner end of the conduit 23. In addition, the outer ring 33 and the inner ring 34 have peripheral flanges 35 and 35 which take between them the horizontal portion of the plate adjacent to its central passage 22 and the horizontal portion of the membrane 31 adjacent its cylindrical edge 32.

La réalisation de l'accouplement ci-dessus peut être obtenue en mettant en oeuvre des outils de compression, faisant en sorte, en outre, que la partie d'extrémité du conduit 23, le bord cylindrique 32 de la membrane souple 31, la bague extérieure 33 et la bague intérieure 34 forment un bourrelet annulaire 35, par exemple vers l'intérieur.The embodiment of the above coupling can be obtained by implementing compression tools, furthermore ensuring that the end portion of the duct 23, the cylindrical edge 32 of the flexible membrane 31, the ring 33 and the inner ring 34 form an annular bead 35, for example inwardly.

Comme illustré sur la figure 8, le dispositif d'évacuation 20 peut être installé sur un toit 36, ou une terrasse, muni d'un conduit d'évacuation 37, de façon équivalente au dispositif d'évacuation 1. le conduit 23 s'étend dans le conduit d'évacuation 37, la membrane souple 31 est placée sur une couche d'étanchéité 38 du toit et peut être fixée sur cette dernière par chauffage, de façon connue en soi.As illustrated on the figure 8 , the evacuation device 20 can be installed on a roof 36, or a terrace, provided with a discharge duct 37, in a manner equivalent to the evacuation device 1. the duct 23 extends in the duct 37, the flexible membrane 31 is placed on a sealing layer 38 of the roof and can be fixed thereto by heating, in a manner known per se.

Selon une variante de réalisation illustrée sur la figure 9, un dispositif d'évacuation 20A se différencie du dispositif d'évacuation 20 principalement par le fait que la paroi verticale fixe 24 est fixée sur la platine 21 par un cordon de soudure extérieur et que la paroi verticale mobile est disposée à l'intérieur de la paroi verticale fixe 24 et prend appui sur la platine 21.According to an embodiment variant illustrated on the figure 9 , an evacuation device 20A differs from the evacuation device 20 mainly in that the fixed vertical wall 24 is fixed on the plate 21 by an external weld bead and the movable vertical wall is disposed inside the the fixed vertical wall 24 and bears on the plate 21.

Selon une variante de réalisation illustrée sur la figure 10, un dispositif d'évacuation 20B se différencie du dispositif d'évacuation 20 ou 20A principalement par le fait que la platine 21, la paroi verticale fixe 24 et la bague intérieure 34 forment une seule pièce 39 pouvant être obtenue à partir d'un flanc de tôle, la collerette 36 n'existant plus. Néanmoins, d'une part, la platine 21 et la paroi verticale fixe 24 pourraient former une seule pièce et la bague intérieure 34 munie de sa collerette 36 pourrait être rapportée comme décrit précédemment. D'autre part, la platine 21 et la bague intérieure 34 pourraient former une seule pièce et la paroi verticale fixe 24 pourrait être rapportée comme décrit précédemment, la collerette 36 n'existant plus.According to an embodiment variant illustrated on the figure 10 , an evacuation device 20B differs from the evacuation device 20 or 20A mainly in that the plate 21, the fixed vertical wall 24 and the inner ring 34 form a single piece 39 that can be obtained from a sidewall of sheet metal, the flange 36 no longer exists. Nevertheless, on the one hand, the plate 21 and the fixed vertical wall 24 could form a single piece and the inner ring 34 provided with its flange 36 could be reported as described above. On the other hand, the plate 21 and the inner ring 34 could form a single piece and the fixed vertical wall 24 could be reported as previously described, the flange 36 no longer exist.

Selon une variante de réalisation illustrée sur la figure 11, un dispositif d'évacuation 40 comprend, autour d'une paroi verticale fixe 41, équivalente à la paroi verticale fixe de l'un quelconque des dispositifs d'évacuation décrits précédemment, une paroi verticale mobile 42 qui présente une fente verticale 43 et, de part et d'autre de cette fente, des rebords verticaux 44 et 45 en vis-à-vis s'étendant vers l'extérieur, la paroi verticale mobile 42 étant par ailleurs configurée de façon équivalente aux parois verticales mobiles des exemples précédents.According to an embodiment variant illustrated on the figure 11 , an evacuation device 40 comprises, around a fixed vertical wall 41, equivalent to the fixed vertical wall of any of the evacuation devices described above, a mobile vertical wall 42 which has a vertical slot 43 and, on either side of this slot, vertical edges 44 and 45 vis-à-vis extending outwardly, the movable vertical wall 42 is also configured equivalent to the movable vertical walls of the previous examples.

Après avoir réglé la paroi verticale mobile 42 par rapport à la paroi verticale fixe 41 comme décrit précédemment, on peut alors fixer les rebords verticaux 44 et 45 entre eux, par exemple grâce à des boulons ou des rivets, non représentés, traversant des trous 46 aménagés au travers d'eux. Les dimensionnements peuvent être telles que lorsque les rebords verticaux 44 et 45 sont rapprochés, la paroi verticale mobile 42 enserre la paroi verticale fixe 41.After having adjusted the movable vertical wall 42 with respect to the fixed vertical wall 41 as previously described, it is then possible to fix the vertical flanges 44 and 45 between them, for example by means of bolts or rivets, not shown, passing through holes 46. arranged through them. The sizing may be such that when the vertical edges 44 and 45 are brought together, the movable vertical wall 42 encloses the fixed vertical wall 41.

Selon une variante de réalisation illustrée sur les figures 12 et 13, un dispositif d'évacuation 50 se différencie des dispositifs d'évacuation décrits précédemment par le fait qu'autour et à distance de parois fixes et mobiles 51 et 52 installées sur une platine 53, est prévue en outre une paroi verticale tubulaire complémentaire 54, par exemple cylindrique, dont le bord inférieure est fixé sur la face supérieure de cette platine 53, de façon étanche.According to an embodiment variant illustrated on the figures 12 and 13 , an evacuation device 50 differs from the evacuation devices described above in that around and away from fixed and movable walls 51 and 52 installed on a plate 53, there is further provided a complementary tubular vertical wall 54, for example cylindrical, whose lower edge is fixed on the upper face of this plate 53, sealingly.

Le dispositif d'évacuation 50 étant installé sur un toit ou une terrasse comme décrit précédemment, la paroi verticale complémentaire 54 constitue un obstacle de rétention d'eau sur le toit ou la terrasse autour de cette paroi verticale complémentaire 54.The evacuation device 50 being installed on a roof or terrace as described above, the complementary vertical wall 54 constitutes a water retention obstacle on the roof or terrace around this complementary vertical wall 54.

Néanmoins, lorsque le niveau de l'eau sur le toit ou la terrasse atteint ou dépasse le bord supérieur de la paroi verticale complémentaire 54, l'eau déborde et se déverse dans l'espace annulaire 55 séparant les parois fixes et mobiles 51 et 52 et la paroi verticale complémentaire 54 puis s'écoule au travers des passages réglables calibrés 56 créés au travers des parois fixes et mobiles 51 et 52 comme décrit précédemment, pour être évacuée.Nevertheless, when the level of the water on the roof or terrace reaches or exceeds the upper edge of the complementary vertical wall 54, the water overflows and empties into the annular space 55 separating the fixed and movable walls 51 and 52 and the complementary vertical wall 54 then flows through the calibrated adjustable passages 56 created through the fixed and movable walls 51 and 52 as previously described, to be evacuated.

Selon une variante de réalisation illustrée sur les figures 14 et 15, un dispositif d'évacuation 60 se différencie du dispositif d'évacuation 50 décrit en référence aux figures 12 et 13 par le fait qu'il comprend une paroi verticale complémentaire 61 qui n'est plus fixée mais qui présente un bord inférieur pouvant venir en appui sur un joint annulaire 63 fixé sur une platine 62.According to an embodiment variant illustrated on the figures 14 and 15 , an evacuation device 60 differs from the evacuation device 50 described with reference to the figures 12 and 13 in that it comprises a complementary vertical wall 61 which is no longer fixed but which has a lower edge that can bear on an annular seal 63 fixed on a plate 62.

Le dispositif d'évacuation 60 est équipé de barres verticales de guidage 64, par exemple au nombre de quatre, qui sont placées à l'intérieur de la paroi verticale complémentaire 61, à faible distance et réparties périphériquement, et dont les extrémités inférieures sont fixées sur la platine 62.The evacuation device 60 is equipped with vertical guide bars 64, for example four in number, which are placed inside the complementary vertical wall 61, at a short distance and distributed peripherally, and whose lower ends are fixed. on the plate 62.

A l'extérieur, la paroi verticale complémentaire 61 est munie d'un flotteur 65, par exemple annulaire, situé à distance au-dessus de la platine 62.Outside, the complementary vertical wall 61 is provided with a float 65, for example annular, located at a distance above the plate 62.

Le dispositif d'évacuation 60 étant installé sur un toit ou une terrasse comme décrit précédemment, la paroi verticale complémentaire 61, en appui sur le joint annulaire 63, constitue un obstacle de rétention d'eau sur le toit ou la terrasse autour de cette paroi verticale complémentaire 61.The evacuation device 60 being installed on a roof or terrace as described above, the vertical wall complementary 61, bearing on the annular seal 63, constitutes a water retention obstacle on the roof or the terrace around this complementary vertical wall 61.

Néanmoins, lorsque le niveau de l'eau sur le toit ou la terrasse atteint le flotteur 65 et monte, la paroi verticale complémentaire 61 monte sous l'effet du flotteur et l'eau s'écoule sous la paroi verticale complémentaire 61, vers l'espace annulaire 66 séparant des parois fixes et mobiles 67 et 68 et la paroi verticale complémentaire 61 puis s'écoule au travers des passages réglables calibrés 69 créés au travers des parois fixes et mobiles 51 et 52 comme décrit précédemment pour être évacuée.Nevertheless, when the level of the water on the roof or terrace reaches the float 65 and rises, the complementary vertical wall 61 rises under the effect of the float and the water flows under the complementary vertical wall 61, towards the annular space 66 separating fixed and movable walls 67 and 68 and the complementary vertical wall 61 and flows through calibrated adjustable passages 69 created through the fixed and movable walls 51 and 52 as previously described to be evacuated.

Quand le niveau de l'eau redescend, la paroi verticale complémentaire 61 redescend en appui sur le joint 63 et retient à nouveau l'eau.When the water level drops, the complementary vertical wall 61 back down on the seal 63 and retains the water.

Pour limiter la course vers le haut de la paroi verticale complémentaire 61, les extrémités supérieures 64a des barres verticales 64 peuvent être coudées vers l'extérieur pour s'étendre au-dessus du bord supérieur de la paroi verticale complémentaire 61, en formant ainsi des butées supérieures, de telle sorte que la paroi verticale complémentaire 61 est mobile verticalement entre d'une part le joint 63 porté par la platine 62 et les extrémités 65a coudées des barres de guidage 65.To limit the upward travel of the complementary vertical wall 61, the upper ends 64a of the vertical bars 64 may be bent outward to extend above the upper edge of the complementary vertical wall 61, thereby forming upper stops, such that the complementary vertical wall 61 is vertically movable between on the one hand the seal 63 carried by the plate 62 and the ends 65a bent of the guide bars 65.

La présente invention ne se limite pas aux exemples ci-dessus décrits. En particulier, les ouvertures aménagées dans les parois fixes et mobiles pourraient être de formes différentes, par exemple rondes, ovales, triangulaires ou en forme de losanges. Les parois fixes et mobiles pourraient être de formes et de hauteurs différentes. D'autres dispositifs d'évacuation pourraient être obtenus en combinant différemment les différentes structures décrites. Au lieu que la paroi verticale mobile soit réglage par rotation, cette paroi pourrait être réglable par déplacement vertical de façon à régler le débit maximum d'écoulement. Bien d'autres variantes de réalisation sont possibles, sans sortir du cadre défini par les revendications annexées.The present invention is not limited to the examples described above. In particular, the openings in the fixed and movable walls could be of different shapes, for example round, oval, triangular or diamond-shaped. The fixed and mobile walls could be of different shapes and heights. Other evacuation devices could be obtained by combining the different structures described differently. Instead of the movable vertical wall being rotational, this wall could be adjustable by vertical movement to adjust the maximum flow rate.
