Definitions
- the invention relates to a retractable platform for swimming pools.
- the pool has a flat bottom, an inclined bottom or a dihedral bottom, it always presents, on the one hand, at least locally under a diving board, a depth greater than human size and imposing to swim to stay on the surface of the water, and, on the other hand, a smaller area depth, allowing you to walk on the bottom without having to swim to keep your head above water and breathe.
- the object of the present invention is to provide a platform retractable improving the safety of the pool and its conditions of use.
- Another object of the invention is to provide a platform not entailing any risk for swimmers and users.
- each of the tenons of the platform on the one hand is fitted with a low friction nut mounted sliding inside the corresponding well ensuring the guiding vertical translation of this post, on the other hand, is linked to the cable, and, moreover, is linked to the lower end of a flap mounted sliding in rebates bordering the light of the well by closing off the part of this well arranged above of the platform, while each vertical well has, in its part upper and between the maximum filling level of the basin and the level of its peripheral coping, a housing accessible by a hatch and containing, on the one hand, the pulleys ensuring the return of the cable between its vertical path in the well and a horizontal and longitudinal trajectory, outside the pelvis, near the longitudinal wall thereof, and on the other hand, rollers flap return.
- the platform When the pool is used for swimming, the platform is placed on the bottom of the basin.
- the lifting device is activated so as to impart a longitudinal tensile force to the cables causing, by their strands arranged in the wells, the elevation of the platform to the desired height, i.e. so that the upper side of the platform is slightly above the water level of the basin.
- the platform forms a floor opposing any penetration in water, both for a child and for an animal, and therefore avoids risk of drowning.
- the platform is partially raised, so that, for example, players walking on it have water to the waist.
- the lifting device allows you to change the vertical level of the platform, whether or not it supports swimmers. It therefore allows to adapt the useful level of the basin according to needs, which is very interesting for muscle rehabilitation of people or disabled.
- At least one of the flaps has, on its face facing the basin, a graduation indicating the depth of penetration of the platform below the level of the basin, while a wall closing the upper part of the lumen of the corresponding well comprises a window allowing to read the graduation.
- This arrangement allows, by reading out of the water, and at all times, to know the stopping depth of the platform either for adapt the nautical activity, either to adapt the degree of surveillance of less good swimmers.
- the reference numeral 2 denotes, so general, the rectangular basin of a swimming pool surrounded by a coping 3 and fitted with at least one ladder 4.
- Platform 1 is made up of a frame 6 made up of two long sides 7a and two short sides 7b. This framework is reinforced by crosspieces 8, parallel to the short sides 7b, and the distribution pitch of which is defined in relation to the dimension of the elements of a grating 9, reported on these sleepers.
- the frame and the crosspieces are made up of profiles tubular, for example, of rectangular section, made of metal alloy resistant to chlorinated water, for example, stainless steel.
- Figures 1 and 2 show that the platform has, plan view from above, the same shape as the basin 2 on which it is placed, but has dimensions less than those of the basin, so as to be able to slide therein, without coming into contact with its longitudinal and transverse walls.
- the spar 7a of the frame 6 is conformed in 7d to bypass the part of this staircase which overflows into the pool.
- each crosspiece 8a contains a metal part 12 comprising two threaded bores 13 in which are screwed the ends of screws 14 whose bodies pass through and are supported on the part of the tenon 10 disposed in the basin 2.
- Each tenon projects beyond the spar 7a to form a projection 10a. This projection penetrates in a vertical well 15, made for example of sheet metal, communicating with the pelvis by a vertical light 16.
- This projecting part 10a is fitted in a guide nut 17, made of material having a low coefficient friction, whose shapes and dimensions allow it to slide at inside the well 15 ensuring the guiding in vertical translation of the post 10.
- the nut 17 and the part 10a of the tenon 10 are crossed by bores coaxial verticals, respectively 18 and 19, for the passage of a cable 20 whose free end is provided with a cable stop 22 which drowns in a stepped bore 23 of the post.
- Figure 4 shows that on the side walls 15a of the well 15, are fixed square metal profiles 24 which define, against each of the edges of the light 16, a rebate 25 for guiding the edges of a flap 26.
- This flap which is produced in a deformable ply, is fixed by its lower end to each tenon 10 by any known means, and for example, by a screwed fixing bracket 27 on the post and on its end.
- each well 15 is secured to a housing, generally designated by reference 28.
- This housing which is closed by a hatch 29, supports, by through a gusset 30, two horizontal axes 32 and 33, parallel to the side members 7a of the platform.
- Pulleys, respectively 34 and 35 are freely mounted in rotation on the aforementioned axes 32 and 33 and allow the return of the lifting cable 20 between the vertical strand 20a, disposed in the well, and a another vertical section 20b leading to a return pulley 36.
- This pulley is mounted free in rotation on an axis 37, perpendicular to those 32 and 33, and carried by a wall 38 delimiting, with the rear wall of the housing 28, a channel rear 39.
- Figure 3 shows that the gusset 30 carries, also between the two pulleys 34 and 35, a deflector 40 preventing that, under the action of the choppers from the basin, the water contained in the vertical well 15 escapes from it in increasing the water consumption of the pool.
- the housing 28 also contains return rollers 42 which organize the path of the flap of the flap 26, so that the rear strand flap can flow vertically in the rear channel 39, where it is placed tension by a counterweight 43.
- each section of cable 20 passes over a return pulley 44, 45, pivoting about a vertical axis, to forming a section of transverse cable 20d and 20e.
- the section 20d comes above the section 20e with which it is attached to the end of a drawing member 50.
- the different sections of cables 20c to 20th run in troughs 52 which are arranged under the coping 3 of the basin 2, while the drawing member is arranged in a pit 53, which may be that containing the means for treating the water of the pool.
- the pulling member 50 is constituted by a jack whose body 50a is fixed and whose rod 50b is provided with its end, means for hooking the sections of the four cables of draw 20 reaching the four wells 15 associated with the four tenons 10.
- This hydraulic cylinder single acting or double acting, is powered by pipes 54 coming from a hydraulic unit 55, itself under the control of a control box 56.
- Figure 1 shows that this control unit 56 is arranged in a terminal 56, and can for example be actuated by a digital keyboard 57.
- platform 1 For normal use of the pool, platform 1 is arranged against the bottom of the pool. At the end of the swimming period, the platform is moved vertically by means of the lifting cables 20, so that its upper face comes substantially above the level N of the water in the basin, as shown in Figure 3. In this position, the platform forms a screen which, even in the event of a child or animal falling into the basin, avoid any contact of it with water and therefore removes all risk of drowning.
- ballast material such as concrete or equivalent.
- Figure 1 shows that, for the practice of certain nautical games, platform 1 can be brought to half height, so as to allow players to walk on it while having water at least up to size.
- At least one of the components forms platform level indicator.
- the face of the flap 26, which is facing the pool has a 60 scale indicating the level of penetration of the platform, therefore the height of water above from it and the upper part of the light 16 of the corresponding well 15 is obscured by a wall 61 which carries a reading window 62, in its part out of water.
- This graduation can be made up by numbers indicating a depth in centimeters or other unit of linear measurement, but also by colored sections of colors increasingly darker in relation to depth to simplify reading by young children.

Description
L'invention concerne une plate-forme escamotable pour piscine.The invention relates to a retractable platform for swimming pools.
Il est connu que le bassin d'une piscine constitue un danger réel pour les jeunes enfant qui, en l'absence de barrières de protection entourant le bassin, ou de moyens l'occultant, peuvent chuter dans l'eau et se noyer.It is known that the pool of a swimming pool constitutes a real danger for young children who, in the absence of protective barriers surrounding the basin, or of the occulting means, can fall in water and drown.
Par ailleurs, que la piscine ait un fond plat, un fond incliné ou un fond dièdrique, elle présente toujours, d'une part, au moins localement sous un plongeoir, une profondeur supérieure à la taille humaine et imposant de nager pour rester à la surface de l'eau, et, d'autre part, une zone de moins grande profondeur, permettant de marcher sur le fond sans avoir besoin de nager pour garder la tête hors de l'eau et respirer.In addition, whether the pool has a flat bottom, an inclined bottom or a dihedral bottom, it always presents, on the one hand, at least locally under a diving board, a depth greater than human size and imposing to swim to stay on the surface of the water, and, on the other hand, a smaller area depth, allowing you to walk on the bottom without having to swim to keep your head above water and breathe.
Ces variations de profondeur entre deux zones opposées d'un bassin constituent une gêne pour certains sports nautiques et, par exemple, défavorisent les joueurs de l'équipe disposés en zone profonde par rapport à ceux disposés en zone moins profonde dans le cadre de jeux de ballons, de type water-polo.These variations in depth between two opposite zones of a basin are a nuisance for certain water sports and, for example, disadvantage team players placed in the deep zone compared to those placed in shallower areas for ball games, water polo type.
La présente invention a pour objet de fournir une plate-forme escamotable améliorant la sécurité du bassin et ses conditions d'utilisation.The object of the present invention is to provide a platform retractable improving the safety of the pool and its conditions of use.
On connaít, par le brevet US-A 3 045 253, une plate-forme qui, composée d'un cadre inséré dans le bassin et ayant les mêmes dimensions que lui, supporte un caillebotis et comporte, en saillie, des tenons transversaux mobiles dans des puits verticaux et reliés chacun au brin vertical d'un câble coopérant avec des moyens moteurs permettant le soulèvement de la plate-forme ou son abaissement.We know, from US-A 3,045,253, a platform which, composed of a frame inserted in the basin and having the same dimensions that it supports a grating and has, projecting, transverse studs movable in vertical shafts and each connected to the vertical strand of a cable cooperating with motor means allowing the lifting of the platform or its lowering.
Que ces moyens moteurs soient des vérins hydrauliques noyés dans les puits ou un tambour enroulant les brins horizontaux des câbles, formés par renvoi des brins verticaux sur des poulies disposées en tête des puits, les brins verticaux restent visibles et accessibles dans leurs puits respectifs et peuvent être une source d'accident pour les baigneurs.That these motor means are flooded hydraulic cylinders in the wells or a drum winding the horizontal strands of the cables, formed by returning the vertical strands on pulleys arranged at the head of the wells, the vertical strands remain visible and accessible in their wells respective and can be a source of accident for swimmers.
Les mêmes inconvénients se retrouvent dans le dispositif décrit dans le brevet US-A 5 271 483 mettant en oeuvre une plate-forme avec des tenons, des câbles circulant dans les puits et des moyens moteurs pour déplacer ces câbles et assurer leur calage en position.The same drawbacks are found in the device described in patent US-A 5,271,483 implementing a platform with tenons, cables circulating in the wells and motor means for move these cables and secure them in position.
Un autre objet de l'invention est de fournir une plate-forme n'entraínant aucun risque pour les baigneurs et utilisateurs. Another object of the invention is to provide a platform not entailing any risk for swimmers and users.
A cet effet, et selon l'invention, chacun des tenons de la plate-forme d'une part, est muni d'une noix à faible coefficient de frottement montée coulissante à l'intérieur du puits correspondant en assurant le guidage en translation verticale de ce tenon, d'autre part, est lié au câble, et, de plus, est lié à l'extrémité inférieure d'un volet monté coulissant dans des feuillures bordant la lumière du puits en obturant la partie de ce puits disposé au-dessus de la plate-forme, tandis que chaque puits vertical comporte, dans sa partie supérieure et entre le niveau maximum de remplissage du bassin et le niveau de sa margelle périphérique, un boítier accessible par une trappe et contenant, d'une' part, les poulies assurant le renvoi du câble entre sa trajectoire verticale dans le puits et une trajectoire horizontale et longitudinale, à l'extérieur du bassin, près de la paroi longitudinale de celui-ci, et d'autre part, des rouleaux de renvoi du volet.To this end, and according to the invention, each of the tenons of the platform on the one hand, is fitted with a low friction nut mounted sliding inside the corresponding well ensuring the guiding vertical translation of this post, on the other hand, is linked to the cable, and, moreover, is linked to the lower end of a flap mounted sliding in rebates bordering the light of the well by closing off the part of this well arranged above of the platform, while each vertical well has, in its part upper and between the maximum filling level of the basin and the level of its peripheral coping, a housing accessible by a hatch and containing, on the one hand, the pulleys ensuring the return of the cable between its vertical path in the well and a horizontal and longitudinal trajectory, outside the pelvis, near the longitudinal wall thereof, and on the other hand, rollers flap return.
Grâce aux noix, les mouvements de la plate-forme sont parfaitement guidés et celle-ci n'est soumise à aucun mouvement horizontal, lorsqu'elle est utilisée comme plate-forme de jeux nautiques. Par ailleurs, les volets s'opposent à toute introduction de corps étranger dans les puits et suppriment tous risques d'accident, tout en n'altérant pas l'esthétique du bassin.Thanks to the nuts, the movements of the platform are perfectly guided and it is not subjected to any horizontal movement, when used as a water games platform. In addition, flaps oppose any introduction of foreign bodies into the wells and eliminate any risk of accident, while not altering the aesthetics of the pool.
Lorsque la piscine est utilisée pour la natation, la plate-forme est posée sur le fond du bassin. En fin de la séance de natation, par exemple, pour mettre la piscine en position de sécurité, l'organe de levage est actionné de manière à communiquer aux câbles un effort de traction longitudinale entraínant, par leurs brins disposés dans les puits, l'élévation de la plate-forme jusqu'à la hauteur voulue, c'est-à-dire de manière que la face supérieure de la plate-forme soit légèrement au-dessus du niveau de l'eau du bassin. Dans cette position, la plate-forme forme un plancher s'opposant à toute pénétration dans l'eau, aussi bien pour un enfant, que pour un animal, et évite donc les risques de noyade.When the pool is used for swimming, the platform is placed on the bottom of the basin. At the end of the swimming session, for example, to put the pool in the safety position, the lifting device is activated so as to impart a longitudinal tensile force to the cables causing, by their strands arranged in the wells, the elevation of the platform to the desired height, i.e. so that the upper side of the platform is slightly above the water level of the basin. In this position, the platform forms a floor opposing any penetration in water, both for a child and for an animal, and therefore avoids risk of drowning.
Pour la pratique de jeux nautiques, la plate-forme est partiellement relevée, de manière, par exemple, que les joueurs marchant sur elle, aient de l'eau jusqu'à la taille.For the practice of nautical games, the platform is partially raised, so that, for example, players walking on it have water to the waist.
Le dispositif de levage permet de modifier le niveau vertical de la plate-forme, que celle-ci supporte ou non des baigneurs. Il permet donc d'adapter le niveau utile du bassin en fonction des besoins, ce qui est très intéressant pour la rééducation musculaire des personnes ou handicapés. The lifting device allows you to change the vertical level of the platform, whether or not it supports swimmers. It therefore allows to adapt the useful level of the basin according to needs, which is very interesting for muscle rehabilitation of people or disabled.
Il est précisé que, si les mouvements d'élévation de la plate-forme sont effectués par les câbles de levage, les mouvements de descente sont assurés par le seul poids de la plate-forme qui, grâce à sa structure lacunaire, est peu freinée par l'eau du bassin.It is specified that, if the elevation movements of the platform are carried out by the lifting cables, the lowering movements are ensured by the sole weight of the platform which, thanks to its incomplete structure, is not slowed down by the water in the basin.
Avantageusement, au moins l'un des volets comporte, sur sa face tournée vers le bassin, une graduation indiquant la profondeur d'enfoncement de la plate-forme au-dessous du niveau du bassin, tandis qu'une paroi obturant la partie supérieure de la lumière du puits correspondant comporte une fenêtre permettant de lire la graduation.Advantageously, at least one of the flaps has, on its face facing the basin, a graduation indicating the depth of penetration of the platform below the level of the basin, while a wall closing the upper part of the lumen of the corresponding well comprises a window allowing to read the graduation.
Cet aménagement permet, par une lecture effectuée hors de l'eau, et à tout instant, de connaítre la profondeur d'arrêt de la plate-forme soit pour adapter l'activité nautique, soit pour adapter le degré de surveillance des moins bons nageurs.This arrangement allows, by reading out of the water, and at all times, to know the stopping depth of the platform either for adapt the nautical activity, either to adapt the degree of surveillance of less good swimmers.
D'autres caractéristiques et avantages ressortiront de la description
qui suit en référence au dessin schématique annexé représentant une forme
d'exécution de cette plate-forme dans le cas de son application à une piscine
dont le bassin est rectangulaire, comporte un fond horizontal et plat et des
parois longitudinales sans déversoir.
Dans ce dessin, la référence numérique 2 désigne, de manière
générale, le bassin rectangulaire d'une piscine entourée par une margelle 3 et
munie d'au moins une échelle 4.In this drawing, the reference numeral 2 denotes, so
general, the rectangular basin of a swimming pool surrounded by a coping 3 and
fitted with at least one
La plate-forme 1 est composée d'un cadre 6 composé de deux grands côtés 7a et de deux petits côtés 7b. Ce cadre est renforcé par des traverses 8, parallèles aux petits côtés 7b, et dont le pas de répartition est défini en rapport avec la dimension des éléments d'un caillebotis 9, rapporté sur ces traverses. Le cadre et les traverses sont constitués par des profilés tubulaires, par exemple, de section rectangulaire, réalisés en alliage métallique résistant à l'eau chlorée, par exemple, en acier inoxydable. Les figures 1 et 2 montrent que la plate-forme a, vue en plan par dessus, la même forme que le bassin 2 sur lequel elle est disposée, mais a des dimensions inférieures à celles du bassin, de manière à pouvoir coulisser dans celui-ci, sans venir en contact avec ses parois longitudinales et transversales.Platform 1 is made up of a frame 6 made up of two long sides 7a and two short sides 7b. This framework is reinforced by crosspieces 8, parallel to the short sides 7b, and the distribution pitch of which is defined in relation to the dimension of the elements of a grating 9, reported on these sleepers. The frame and the crosspieces are made up of profiles tubular, for example, of rectangular section, made of metal alloy resistant to chlorinated water, for example, stainless steel. Figures 1 and 2 show that the platform has, plan view from above, the same shape as the basin 2 on which it is placed, but has dimensions less than those of the basin, so as to be able to slide therein, without coming into contact with its longitudinal and transverse walls.
Par ailleurs, au niveau de l'échelle 4, le longeron 7a du cadre 6 est
conformé en 7d pour contourner la partie de cet escalier qui déborde dans le
bassin.Furthermore, at the level of the
Deux des traverses, et par exemple, celles 8a et 8b aux figures 1
et 2, sont solidaires, à chacune de leurs extrémités, de tenons 10. Plus
précisément, et comme montré figures 3 et 4, l'extrémité de chaque traverse
8a contient une pièce métallique 12 comportant deux alésages taraudés 13
dans lesquels se vissent les extrémités de vis 14 dont les corps traversent et
prennent appui sur la partie du tenon 10 disposé dans le bassin 2. Chaque
tenon déborde du longeron 7a pour former une saillie 10a. Cette saillie pénètre
dans un puits vertical 15, réalisé par exemple en tôle, communiquant avec le
bassin par une lumière verticale 16. Cette partie en saillie 10a s'emmanche
dans une noix de guidage 17, réalisée en matériau ayant un faible coefficient
de frottement, dont les formes et dimensions lui permettent de coulisser à
l'intérieur du puits 15 en assurant le guidage en translation verticale du tenon
10. La noix 17 et la partie 10a du tenon 10 sont traversées par des alésages
verticaux coaxiaux, respectivement 18 et 19, pour le passage d'un câble 20
dont l'extrémité libre est munie d'un arrêt de câble 22 qui se noie dans un
alésage épaulé 23 du tenon. La figure 4 montre que, sur les parois latérales
15a du puits 15, sont fixés des profilés métalliques en équerre 24 qui
délimitent, contre chacun des bords de la lumière 16, une feuillure 25
d'autoguidage des bords d'un volet 26. Ce volet, qui est réalisé dans une
nappe déformable, est fixé par son extrémité inférieure sur chaque tenon 10
par tout moyen connu, et par exemple, par une équerre de fixation 27 vissée
sur le tenon et sur son extrémité.Two of the sleepers, and for example, those 8a and 8b in Figures 1
and 2, are integral, at each of their ends, with
Dans sa partie supérieure, c'est-à-dire entre sa partie dépassant du
niveau N de remplissage maximum du bassin et du niveau M de la margelle du
bassin, chaque puits 15 est solidaire d'un boítier, désigné de façon générale
par la référence 28. Ce boítier, qui est obturé par une trappe 29, supporte, par
l'intermédiaire d'un gousset 30, deux axes horizontaux 32 et 33, parallèles aux
longerons 7a de la plate-forme. Des poulies, respectivement 34 et 35, sont
montées libres en rotation sur les axes 32 et 33 précités et permettent le renvoi
du câble de levage 20 entre le brin vertical 20a, disposé dans le puits, et un
autre tronçon vertical 20b aboutissant à une poulie de renvoi 36. Cette poulie
est montée libre en rotation sur un axe 37, perpendiculaire à ceux 32 et 33, et
porté par une paroi 38 délimitant, avec la paroi arrière du boítier 28, un canal
arrière 39.In its upper part, that is to say between its part protruding from the
level N of maximum filling of the basin and level M of the edge of the
basin, each
La figure 3 montre que le gousset 30 porte, également entre les
deux poulies 34 et 35, un déflecteur 40 évitant que, sous l'action des clapots
du bassin, l'eau contenue dans le puits vertical 15 s'échappe de celui-ci en
augmentant la consommation d'eau de la piscine.Figure 3 shows that the
Le boítier 28 contient également des rouleaux de renvoi 42 qui
organisent la trajectoire de la nappe du volet 26, de manière que le brin arrière
de volet puisse circuler verticalement dans le canal arrière 39, où il est mis en
tension par un contrepoids 43.The
Comme le montre plus en détails la figure 2, les poulies 36,
associées à chaque puits 15, renvoient le câble de tirage 20 correspondant
suivant une trajectoire horizontale 20c, qui est sensiblement parallèle au plus
grand côté du bassin. A son autre extrémité, chaque tronçon de câble 20
passe sur une poulie de renvoi 44, 45, pivotante autour d'un axe vertical, pour
former un tronçon de câble transversal 20d et 20e. Après renvoi sur une
seconde poulie 46, le tronçon 20d vient au-dessus du tronçon 20e avec lequel
il est accroché à l'extrémité d'un organe de tirage 50. Durant leur trajectoire
entre le puits respectif et l'organe de tirage 50, les différents tronçons de
câbles 20c à 20e cheminent dans des goulottes 52 qui sont disposées sous la
margelle 3 du bassin 2, tandis que l'organe de tirage est disposé dans une
fosse 53, pouvant être celle contenant les moyens de traitement de l'eau du
bassin.As shown in more detail in FIG. 2, the
Dans la forme d'exécution représentée, l'organe de tirage 50 est
constitué par un vérin dont le corps 50a est fixe et dont la tige 50b est munie, à
son extrémité, de moyens d'accrochage des tronçons des quatre câbles de
tirage 20 parvenant aux quatre puits 15 associés aux quatre tenons 10. Ce
vérin hydraulique, à simple effet ou à double effet, est alimenté par des
canalisations 54 provenant d'un groupe hydraulique 55, lui-même sous le
contrôle d'un boítier de commande 56.In the embodiment shown, the pulling
La figure 1 montre que ce boítier de commande 56 est disposé
dans une borne 56, et peut par exemple être actionné par un clavier digital 57. Figure 1 shows that this
Pour l'utilisation normale du bassin, la plate-forme 1 est disposée contre le fond de la piscine. A la fin de la période de baignade, la plate-forme est déplacée verticalement au moyen des câbles de levage 20, de manière que sa face supérieure vienne sensiblement au-dessus du niveau N de l'eau dans le bassin, comme montré à la figure 3. Dans cette position, la plate-forme forme un écran qui, même en cas de chute d'un enfant ou d'un animal dans le bassin, évite tout contact de celui-ci avec l'eau et supprime donc tous les risques de noyade.For normal use of the pool, platform 1 is arranged against the bottom of the pool. At the end of the swimming period, the platform is moved vertically by means of the lifting cables 20, so that its upper face comes substantially above the level N of the water in the basin, as shown in Figure 3. In this position, the platform forms a screen which, even in the event of a child or animal falling into the basin, avoid any contact of it with water and therefore removes all risk of drowning.
En début de baignade, pour dégager le bassin, il suffit de
i commander l'abaissement de la plate-forme en mettant, à l'échappement, la
chambre du vérin 50, afin que le seul poids de la plate-forme provoque son
abaissement dans le bassin.At the start of swimming, to clear the pool, just
i order the lowering of the platform by putting, at the exhaust, the
On notera à cet effet que, si le poids de la plate-forme 6 est insuffisant, tout ou partie des profilés 7a, 7b et 8 la constituant est garnie intérieurement par un matériau de lestage, tel que béton ou équivalent.It will be noted for this purpose that, if the weight of the platform 6 is insufficient, all or part of the sections 7a, 7b and 8 constituting it is filled internally by a ballast material, such as concrete or equivalent.
La figure 1 montre que, pour la pratique de certains jeux nautiques, la plate-forme 1 peut être amenée à mi hauteur, de manière à permettre aux joueurs de marcher sur elle, tout en ayant de l'eau au moins jusqu'à hauteur de la taille.Figure 1 shows that, for the practice of certain nautical games, platform 1 can be brought to half height, so as to allow players to walk on it while having water at least up to size.
En raison du guidage assuré par les tenons 10, les sollicitations qui
sont communiquées à la plate-forme 6 par les mouvements des joueurs
marchant sur elle, sont sans conséquence pour ces moyens de guidage, ni
d'ailleurs pour les parois du bassin puisque, comme le montre la figure 2, les
guidages positionnent la plate-forme 6 de manière, qu'en aucun cas, ses bords
périphériques puissent venir en contact avec les parois de ce bassin.Due to the guidance provided by the
Quelle que soit la position verticale de la plate-forme 6 dans le
bassin, les lumières 16 ménagées dans les puits 15 pour le passage vertical
des tenons 10, sont toujours occultées par les volets 26, dans leurs parties
comprises entre la plate-forme 6 et la margelle 3, ce qui évite les accidents.
Cette occultation suit les mouvements de la plate-forme puisque, dans un
sens, chaque volet est tiré par le tenon et dans l'autre par son contrepoids.Whatever the vertical position of platform 6 in the
basin, the
Dans une forme d'exécution, au moins l'un des volets, forme indicateur du niveau de la plate-forme.In one embodiment, at least one of the components, forms platform level indicator.
A cet effet, et comme montré figure 3, la face du volet 26, qui est
tournée en direction du bassin, comporte une graduation 60 indiquant le

Ainsi, au fur et à mesure que la plate-forme se déplace, le volet et la graduation qu'il porte, font de même et permettant à tout instant de connaítre la profondeur de la plateforme. Cette graduation peut être constituée par des nombres indiquant une profondeur en centimètre ou autre unité de mesure linéaire, mais aussi par des tronçons colorés de couleurs de plus en plus sombre en rapport avec la profondeur pour simplifier la lecture par les enfants en bas âge.So, as the platform moves, the flap and the graduation which it carries, do the same and allowing at any time to know the depth of the platform. This graduation can be made up by numbers indicating a depth in centimeters or other unit of linear measurement, but also by colored sections of colors increasingly darker in relation to depth to simplify reading by young children.
