Description

La présente invention concerne un dispositif pour générer au moins une vague artificielle ainsi que l'installation pour la mise en oeuvre du dudit dispositif ainsi que l'utilisation de cette au moins une vague pour la pratique de sports de glisse sur l'eau.The present invention relates to a device for generating at least one artificial wave as well as the installation for the implementation of said device as well as the use of this at least one wave for the practice of sliding sports on the water.

Le document WO2013/071362 est regardé comme l'art antérieur le plus proche.The document WO2013 / 071362 is regarded as the closest prior art.

On connaît différentes disciplines de sport de glisse sur l'eau dont une des plus anciennes qui est le surf.We know different disciplines of water sports on the water, one of the oldest of which is surfing.

Le surf se pratique avec un support flottant, notamment une planche flottante sur laquelle le pratiquant se tient allongé et/ou debout. Le pratiquant se positionne par rapport aux vagues naturelles générées par l'Océan, en un endroit adapté dit pic de la vague, se propulse pour vaincre une partie de sa propre inertie et profite de la pente de la vague pour glisser, cette pente se renouvelant sous sa planche de façon continue grâce au phénomène ondulatoire de la houle. Cette vague doit avoir une pente suffisante pour permettre de surfer.The surf is practiced with a floating support, including a floating board on which the practitioner is lying and / or standing. The practitioner positions himself in relation to the natural waves generated by the ocean, in a suitable place called peak of the wave, propels himself to overcome a part of his own inertia and takes advantage of the slope of the wave to slide, this slope being renewed under his board in a continuous way thanks to the wave phenomenon of the swell. This wave must have a slope sufficient to allow surfing.

La vague se creuse aux abords du bord de mer car la base est freinée au contact du fond tandis que la partie haute sous l'effet de l'inertie accumulée poursuit à la même vitesse. La vague uniquement ondulatoire initialement se creuse et la pente augmente jusqu'à devenir instable et à ce moment-là, il se produit un phénomène de déferlement jusqu'à l'éclatement total du système ondulatoire avec un bouillonnement, brassage de la masse d'eau dont la dernière énergie est dissipée au contact du bord rocheux ou sablonneux.The wave widens around the seaside because the base is braked in contact with the bottom while the upper part under the effect of accumulated inertia continues at the same speed. The only wave wave initially widens and the slope increases until becoming unstable and at that moment, there is a breaking phenomenon until the total burst of the wave system with a bubbling, mixing of the mass of water whose last energy is dissipated in contact with the rocky or sandy edge.

Dès lors on comprend que, pour la pratique du surf, les conditions naturelles doivent présenter de nombreuses caractéristiques.Therefore we understand that for the practice of surfing, natural conditions must have many features.

D'une part il faut de la houle, celle-ci est générée au large par les phénomènes de tempête mais il faut, en fonction du niveau de pratique du sportif, une hauteur de vague adaptée, ce qui limite déjà le nombre d'opportunités.On the one hand it takes swell, it is generated offshore by storm phenomena but it is necessary, depending on the level of practice of the athlete, a suitable wave height, which already limits the number of opportunities .

Ensuite la marée joue un rôle car, à marée montante, les vagues ne sont pas contrariées par le recul de la masse d'eau générale et sont donc plus motrices. Le vent, suivant son orientation peut aussi contrarier le phénomène de creusement de la vague et/ou générer un clapot perturbateur de la qualité de ladite vague.Then the tide plays a role because at rising tide, the waves are not thwarted by the decline of the general body of water and are therefore more motor. The wind, according to its orientation can also hinder the phenomenon of digging the wave and / or generate a chop disruptive of the quality of said wave.

Les plus beaux profils de vagues permettant de belles évolutions nécessitent souvent de se rendre en des lieux dits spots, très spécifiques, distants les uns des autres, les distances s'allongeant avec le niveau du surfeur, toujours à la recherche de la vague parfaite. Il faut de toutes les façons se rendre au bord de mer, ce qui n'est pas non plus accessible à tout un chacun.The most beautiful wave profiles for beautiful evolutions often require going to so-called spot locations, very specific, distant from each other, the distances lengthening with the level of the surfer, always in search of the perfect wave. It is necessary anyway to go to the seaside, which is not accessible to everyone.

Ce sport peut s'avérer dangereux pour les débutants qui se hasarderaient dans de mauvaises conditions.This sport can be dangerous for beginners who would venture in bad conditions.

Il est aussi nécessaire de franchir la barre des vagues pour se rendre au-delà de celles-ci et pour se placer de façon adaptée pour partir.It is also necessary to cross the bar of the waves to go beyond these and to place oneself in a suitable way to leave.

Enfin, la durée totale de glisse sur une session est en réalité très limitée.Finally, the total duration of slides on a session is actually very limited.

On constate donc que le surf est un sport de glisse extraordinaire mais qui nécessite un investissement très important pour sa pratique, ce qui le réserve à un nombre restreint de sportifs.We therefore note that surfing is an extraordinary sport of gliding but which requires a very important investment for its practice, which reserves it to a restricted number of sportsmen.

Rapidement après la création des bateaux de loisir, la discipline du ski nautique a vu le jour.Quickly after the creation of recreational boats, the discipline of water skiing was born.

Le ski nautique se pratique soit avec une paire de ski à l'image du ski alpin, soit avec un monoski pour la pratique du slalom. Dans les deux cas, la glisse s'effectue de face. Le bateau se déplace à vitesse élevée, déjaugé, et ne génère donc qu'une très faible hauteur de vague sillage et de vague d'étrave.Water skiing is practiced either with a pair of skis like alpine skiing, or with a monoski for slalom practice. In both cases, the slide is done from the front. The boat moves at a high speed, forwards, and thus generates only a very low wake and bow wave height.

Plus récemment, la combinaison du surf et du ski nautique a fait apparaître le "wakeboard" qui se pratique en traction derrière un bateau avec une corde de traction mais avec un positionnement de profil par rapport à la direction d'avancement, à l'image du snowboard. La sensation de liberté est néanmoins un peu faussée par les chausses qui maintiennent les pieds et qui lient le pratiquant à la planche. Il a donc été inventé le "wakeskate", association entre un sport tracté, le wakeboard, et le "skateboard". Les pieds sont ainsi libres de tout mouvement et la sensation plus proche du surf. Pour des évolutions acrobatiques, il est nécessaire de disposer de vagues de sillage prononcées, ces vagues de sillage formant tremplin lorsque le pratiquant se déplace avec une forte incidence de part et d'autre de la direction de navigation du bateau.More recently, the combination of surfing and water skiing has shown the "wakeboard" which is practiced in traction behind a boat with a traction rope but with a profile position relative to the direction of advancement, in the image snowboarding. The feeling of freedom is nevertheless a little distorted by the shoes that hold the feet and bind the practitioner to the board. It was therefore invented the "wakeskate", an association between a towed sport, wakeboarding and skateboarding. Feet are free of movement and feel closer to the surf. For acrobatic evolutions, it is necessary to have pronounced waves of wake, these waves of wake forming springboard when the practitioner moves with a strong incidence on both sides of the direction of navigation of the boat.

Or la pratique du surf présente cet avantage de ne nécessiter aucun lien avec quoi que ce soit, c'est cette sensation de glisse libre qui est recherchée et qui en fait son succès.But the practice of surfing has the advantage of not requiring any connection with anything, it is this sensation of free gliding which is sought and which makes it its success.

Pour retrouver et récréer cette sensation de surf, la vague de sillage des bateaux a été utilisée, plus récemment, pour surfer, donnant ainsi naissance au "wakesurf". En effet à plus faible vitesse que celles du ski nautique et du wakeboard, la vague peut être suffisamment haute et puissante pour porter un surfeur sans besoin de traction. Les bateaux dédiés au ski nautique et au wakeboard ont ainsi été lestés, ballastés, de l'arrière pour qu'une fois déjaugés, à une vitesse comprise entre 15 et 20 km/h, ils forment un sillage épais, dû à l'enfoncement dynamique de la coque dans l'eau.To find and recreate this surfing sensation, the wake wave of boats has been used, more recently, to surf, giving birth to "wakesurf". In fact, at a slower speed than water skiing and wakeboarding, the wave can be high enough and powerful enough to carry a surfer without the need for traction. Boats dedicated to water skiing and wakeboarding have been weighted, ballasted, from the back so that once they have reached a speed between 15 and 20 km / h, they form a thick wake, due to the depression dynamic of the hull in the water.

Ce sillage est donc profond et de fait, l'eau poussée dynamiquement, remonte et forme des vagues de sillage massives et creuses.This wake is therefore deep and in fact, the water pushed dynamically, goes up and forms waves of massive wake and hollow.

Il est donc possible de générer une vague permanente très creuse, immédiatement derrière le bateau c'est-à-dire à quelques mètres, permettant alors de surfer et de pratiquer une glisse totalement libre. Une traction avec un palonnier permet le lancement du pratiquant en le sortant de l'eau et en lui permettant de surfer la vague, remplaçant ainsi la propulsion avec les bras en milieu océanique.It is therefore possible to generate a very hollow permanent wave, immediately behind the boat that is to say a few meters, allowing then to surf and practice a totally free glide. A pull with a rudder allows the launching of the practitioner by taking it out of the water and in him to surf the wave, replacing the propulsion with the arms in the ocean.

Le palonnier est ensuite lâché et le pratiquant se trouve à surfer librement, contrairement aux autres sports tractés.The rudder is then released and the practitioner is surfing freely, unlike other towed sports.

De nombreux dispositifs ont été imaginés pour modifier et améliorer le profil des vagues de sillage générées.Many devices have been devised to modify and improve the profile of generated wake waves.

Notamment le brevet US 7 140 318 décrit un aileron qui assure un appui dynamique de la coque d'un bateau sur l'eau encore plus important, réglable et proportionnel à la vitesse d'avancement.In particular the patent US 7,140,318 describes a fin that provides a dynamic support of the hull of a boat on the water even more important, adjustable and proportional to the speed of advance.

Néanmoins, cette pratique n'est pas satisfaisante car, même si les bateaux sont des unités navigantes très sophistiquées, ils nécessitent le recours à un moteur à combustible fossile.Nevertheless, this practice is not satisfactory because, even if the boats are very sophisticated sailing units, they require the use of a fossil fuel engine.

De plus, pour générer une telle vague, il est nécessaire d'embarquer des passagers et/ou de ballaster à l'aide de poches à eau de plusieurs centaines de litres. Ces bateaux ont des puissances moteur de l'ordre de 300 à 500 chevaux. Les coûts d'utilisation et de pratique sont donc très élevés, ce qui limite le nombre de pratiquants.In addition, to generate such a wave, it is necessary to embark passengers and / or ballast using water bags of several hundred liters. These boats have engine powers of the order of 300 to 500 horses. The costs of use and practice are therefore very high, which limits the number of practitioners.

Il y a toujours un bruit de moteur, même s'il est limité, en plus de la pollution air et eau inhérente aux gaz d'échappement, en milieu naturel.There is always an engine noise, albeit limited, in addition to the air and water pollution inherent to the exhaust, in the natural environment.

Enfin, il faut des lieux disposant d'une grande longueur d'évolution pour lancer le bateau, pour démarrer et pour faire demi-tour ou pour effectuer un virage. Tous ces inconvénients limitent fortement l'évolution du nombre de pratiquants en wakesurf.Finally, it takes places with a long evolutionary length to launch the boat, to start and to turn around or to make a turn. All these disadvantages severely limit the evolution of the number of practitioners in wakesurfing.

Par ailleurs il existe des installations pour la pratique du wakeboard, du ski ou du surf tracté qui comprennent un circuit à câble fermé, entre des poulies soutenues en hauteur par des pylônes, le câble étant entraîné par une motorisation électrique.Furthermore there are facilities for the practice of wakeboarding, skiing or towed surf which include a closed cable circuit between pulleys supported at height by towers, the cable being driven by an electric motor.

Des liens avec un mécanisme d'accroche débrayable, similaire à celui utilisé dans les téléskis permettent aux pratiquants d'être tractés et de faire des évolutions, notamment sur des structures flottantes formant tremplin, rapportées sur le plan d'eau.Links with a disengageable attachment mechanism, similar to that used in ski lifts allow practitioners to be towed and make evolutions, including floating structures forming a springboard, reported on the water.

Si de telles installations sont beaucoup plus satisfaisantes du point de vue écologique en milieu naturel, les pratiquants restent constamment tractés par une corde, sans la sensation de glisse libre.If such facilities are much more satisfying from an ecological point of view in the natural environment, practitioners are constantly pulled by a rope, without the feeling of free gliding.

On connaît un agencement pour générer une vague, par la demande de brevet EP 2 123 850 qui consiste à réaliser une structure spécifique, en béton, avec un bassin comportant une faible hauteur d'eau avec un dispositif de génération de vague au moyen d'une pièce avec un profil donné, se déplaçant en fond de bassin artificiel, guidée par des rails eux-mêmes placés au fond, la caractéristique étant que cette pièce fait un angle supérieur à 90° par rapport à la direction de déplacement.There is known an arrangement for generating a wave, by the patent application EP 2 123 850 which consists in producing a specific structure, in concrete, with a basin having a low water height with a device for generating a wave by means of a piece with a given profile, moving in the bottom of an artificial basin, guided by rails themselves placed at the bottom, the characteristic being that this part is at an angle greater than 90 ° relative to the direction of travel.

Un tel agencement conduit à générer une vague artificielle parfaitement adaptée, avec un creux, déroulante à l'image d'une vague naturelle. Une telle installation est très sophistiquée et nécessite des investissements très importants qui limitent la diffusion de telles installations.Such an arrangement leads to generating a perfectly adapted artificial wave, with a hollow, drop-down in the image of a natural wave. Such an installation is very sophisticated and requires very large investments which limit the diffusion of such installations.

Un autre inconvénient est l'impact important de telles constructions en béton sur un lieu d'implantation naturel.Another disadvantage is the significant impact of such concrete constructions on a natural place of implantation.

Le but de la présente invention est de proposer un dispositif de génération de vagues en milieu naturel, qui est à très faibles impacts et empreintes écologiques, qui nécessite un faible investissement matériel, qui permet un accès au plus grand nombre, qui peut même être implanté à proximité d'un milieu urbain, qui autorise la pratique du wakesurf ou autre sport de glisse sur vagues tels que le "bodyboard". Le dispositif et les accessoires adaptés sont maintenant décrits suivant un mode de réalisation principal et des variantes, ceci en regard des dessins associés, dessins sur lesquels les différentes figures représentent :

Sur la figure 1, on a représenté une installation 10 sur un plan d'eau en eau intérieure, mettant en oeuvre le dispositif 12 de génération de vagues selon la présente invention.The object of the present invention is to propose a device for generating waves in a natural environment, which has very low impacts and ecological footprints, which requires a low hardware investment, which allows access to the greatest number, which can even be implanted. close to an urban environment, which allows the practice of wakesurfing or other surf sport such as "bodyboarding".

  • Figure 11 : Graph of values obtained by varying the plate,
On the figure 1 , there is shown an installation 10 on a body of water in internal water, implementing the device 12 for generating waves according to the present invention.

Le dispositif 12 de génération de vagues selon la présente invention comprend au moins deux pylônes 14, chacun en appui sur une base 16, reposant au sol ou au fond d'un plan d'eau 18 ou flottant sur ledit plan d'eau, plus particulièrement en eaux intérieures.The wave generation device 12 according to the present invention comprises at least two pylons 14, each resting on a base 16, resting on the ground or on the ground. bottom of a body of water 18 or floating on said body of water, especially inland waters.

Le dispositif est complété par des poulies 20 associées à chaque pylône dont une poulie 20-1 au moins est motrice, entraînée en rotation par une motorisation 22 électrique et une poulie 20-2 de tension, représentée sur le synoptique des figures 8, montée sur l'autre pylône, poulies 20 entre lesquelles est disposé, de façon connue, un câble 24 moteur, en boucle fermée.The device is completed by pulleys 20 associated with each pylon of which at least one pulley 20-1 is driving, driven in rotation by an electric motor 22 and a tension pulley 20-2, shown in the block diagram. figures 8 mounted on the other pylon, pulleys 20 between which is disposed, in a known manner, a motor cable 24, in a closed loop.

En complément, une base 26-1 de départ permet une utilisation de ladite installation par des pratiquants 28, équipés chacun d'un support flottant S personnel tel qu'une planche de surf ou un bodyboard, apte à utiliser la poussée et la puissance d'une vague.In addition, a base 26-1 of departure allows a use of said installation by practitioners 28, each equipped with a personal floating support S such as a surfboard or a bodyboard, able to use the thrust and the power of 'a wave.

De façon préférentielle, pour augmenter les cadences d'utilisation, il est prévu de façon symétrique une autre base 26-2, voir figure 7, à proximité de la poulie 20-2 de tension.Preferably, to increase the rates of use, it is provided symmetrically another base 26-2, see figure 7 near the 20-2 tension pulley.

Le dispositif 12 de génération de vagues selon la présente invention est représenté plus en détail sur les figures 2 à 5 associées. Le dispositif comprend de plus, au moins un lien 30 de traction solidaire du câble 24 par des moyens 32 de solidarisation.The wave generation device 12 according to the present invention is shown in more detail on the Figures 2 to 5 associated. The device further comprises at least one tensile linkage secured to the cable 24 by means 32 for securing.

Ces moyens 32 de solidarisation sont généralement des pinces connues à serrage permanent.These fastening means 32 are generally known clamps permanent clamping.

Le dispositif 12 de génération de vagues comprend un mobile 34, équipé de moyens 36 de reprise des efforts du lien 30 de traction.The wave generating device 12 comprises a mobile 34, equipped with means 36 for taking up the forces of the traction link 30.

Selon le mode de réalisation principal, le lien de traction 30 comprend deux brins 30-1 et 30-2 parallèles, dans l'alignement de la direction D de déplacement. Chaque brin 30-1, 30-2 est solidarisé en deux points 38-1, 38-2 distincts de solidarisation sur le câble 24 de traction. De façon avantageuse, les deux brins sont reliés par des entretoises de façon à former une échelle. Ces entretoises interdisent le passage entre les deux brins, limitent les mouvements des liens lors des virages autour des poulies, tout en autorisant un vrillage.According to the main embodiment, the traction link 30 comprises two parallel strands 30-1 and 30-2, in alignment with the direction of movement D. Each strand 30-1, 30-2 is secured at two distinct points 38-1, 38-2 for securing on the traction cable 24. Advantageously, the two strands are connected by spacers so as to form a scale. These spacers prohibit the passage between the two strands, limit the movements of the links during turns around the pulleys, while allowing twisting.

Ces deux brins 30-1 et 30-2 parallèles sont fixés sur le mobile 34 en deux points 38-1 et 38-2 des moyens 36 de reprise, également alignés suivant la direction D de déplacement du mobile 34.These two parallel strands 30-1 and 30-2 are fixed on the mobile 34 at two points 38-1 and 38-2 of the recovery means 36, also aligned in the direction D of movement of the mobile 34.

Le mobile 34 comprend une coque 40, par exemple en aluminium, creuse pour assurer la flottabilité, de façon préférentielle à volume fermé. Ce volume fermé est éventuellement comblé par de la mousse 42 à porosité fermée, de façon à conserver la flottabilité, même en cas de pénétration accidentelle d'eau dans la coque 40.The mobile 34 comprises a shell 40, for example aluminum, hollow for buoyancy, preferably to closed volume. This closed volume is eventually filled with foam 42 closed porosity, so as to maintain buoyancy, even in case of accidental penetration of water in the hull 40.

Cette coque 40 est munie, si nécessaire, d'un lest 42, en matériau dense tel que du plomb. Dans le cas de présence d'un lest, ce lest est composé de multiples modules de façon à faciliter le transport de la coque sur le lieu d'utilisation, le lest 42 étant introduit postérieurement à la mise à l'eau. Cette conception modulaire permet également un ajustement éventuel du lestage.This shell 40 is provided, if necessary, a ballast 42, of dense material such as lead. In the case of presence of a ballast, this ballast is composed of multiple modules so as to facilitate the transport of the hull at the place of use, the ballast 42 being introduced after launching. This modular design also allows a possible adjustment of the ballast.

Le lest 42 peut aussi être constitué, au moins pour une part d'un volume de la coque, formant réservoir, destiné à recevoir de l'eau qui sert de ballast. L'ajustement est alors très simple, le remplissage initial aussi, et ce lest est assurément non polluant.The ballast 42 may also be constituted, at least partly by a volume of the shell, forming a reservoir, intended to receive water which serves as ballast. The adjustment is then very simple, the initial filling too, and this ballast is certainly non-polluting.

La coque 40 peut comporter également au moins un aileron 44. On entend par aileron, tout moyen immergé tendant à modifier le comportement de ladite coque lors de la navigation, quelle que soit la position dudit aileron sur ladite coque.The hull 40 may also include at least one fin 44. Aileron means any immersed means tending to modify the behavior of said hull during navigation, regardless of the position of said fin on said hull.

En l'occurrence, dans le mode de réalisation symétrique retenu, l'aileron 44 sur la coque 40 comporte un volet 44-1, présentant une surface d'appui transversale et inclinée vers l'avant de façon à générer une composante vers le bas dès lors que ladite coque se déplace dans la direction D d'avancement.In this case, in the symmetrical embodiment chosen, the fin 44 on the shell 40 comprises a flap 44-1, having a transverse bearing surface and inclined forwardly so as to generate a component downwards. when said hull moves in the direction D of advancement.

De façon avantageuse, ce volet 44-1 est articulé et comprend des moyens 45 de réglage de l'incidence de ce volet 44-1 par rapport au plan de ladite coque 40, par exemple sous forme de ridoirs, ceci de façon connue.Advantageously, this flap 44-1 is articulated and comprises means 45 for adjusting the incidence of this flap 44-1 relative to the plane of said shell 40, for example in the form of turnbuckles, this in a known manner.

Ce volet 44-1 est disposé en partie arrière de la coque 40 du mobile 34, par exemple à proximité immédiate du tableau arrière.This flap 44-1 is disposed at the rear of the hull 40 of the mobile 34, for example in the immediate vicinity of the transom.

En complément, l'installation 10 comprend des moyens 46 de lancement du pratiquant, détaillés sur la figure 6.In addition, the installation 10 includes means 46 for launching the practitioner, detailed on the figure 6 .

Ces moyens 46 de lancement sont composés d'un palonnier 48 solidaire d'une des extrémités d'une corde 50 de traction. L'autre extrémité de la corde 50 est solidaire du tambour d'un enrouleur 52, non détaillé, car disponible dans le commerce. La corde 50 de traction est avantageusement munie d'une butée 54 d'enroulement réglable, la longueur résiduelle de corde 50 étant de ce fait ajustable.These launching means 46 are composed of a rudder 48 integral with one end of a traction rope 50. The other end of the rope 50 is integral with the drum of a reel 52, not detailed, because commercially available. The towing rope 50 is advantageously provided with a stop 54 of adjustable winding, the remaining length of rope 50 being thereby adjustable.

L'enrouleur 52 est lui-même solidaire du câble 24 moteur, en boucle fermée, avec un point de fixation, positionné en amont des moyens 32 de solidarisation du lien 30 avec ce même câble 24 moteur.The winder 52 is itself integral with the motor cable 24, in a closed loop, with a point of attachment, positioned upstream of the means 32 for securing the link 30 with the same motor cable 24.

Le dispositif 12 de génération de vagues selon la présente invention fonctionne de la façon suivante au sein de l'installation 10 associée, ceci en regard du synoptique des figures 7.The wave generating device 12 according to the present invention operates as follows within the associated installation 10, this with regard to the synoptic of the figures 7 .

Figure 7A, le pratiquant 28-1 est sur le ponton sous la poulie 20-1, en attente, le câble 24 moteur tourne et entraîne le lien 30 et les deux brins 30-1, 30-2. Le mobile 34 est entraîné en translation sur le plan d'eau. Figure 7A , the 28-1 practitioner is on the pontoon under the 20-1 pulley, waiting, the 24 motor cable rotates and causes the link 30 and the two strands 30-1, 30-2. The mobile 34 is driven in translation on the water.

Le pratiquant a saisi le palonnier 48 des moyens 46 de lancement et pendant l'avancement du mobile sur quelques mètres, la corde 50 se déroule de l'enrouleur 52.The practitioner grasped the rudder 48 of the launching means 46 and during the advancement of the rover over a few meters, the rope 50 unwinds from the reel 52.

Lorsque la corde 50 est totalement déroulée, le pratiquant 28-1 se trouve entraîné avec son support flottant hors du ponton. Figure 7B.When the rope 50 is fully unwound, the practitioner 28-1 is trained with his floating support out of the pontoon. Figure 7B .

Le déplacement du mobile à vitesse nominale, entre 15 et 20 km/h pour donner un ordre de grandeur, provoque un déplacement du mobile incliné et la formation d'un sillage propre.The displacement of the mobile at nominal speed, between 15 and 20 km / h to give an order of magnitude, causes a movement of the inclined mobile and the formation of a clean wake.

Le lest et l'aileron 44, en l'occurrence le volet 44-1, provoquent un enfoncement de l'arrière du mobile flottant et cet appui dynamique génère une vague de sillage prononcée d'une hauteur comprise entre 0,50m et 1,00m pour donner, là encore, un ordre de grandeur.The ballast and the fin 44, in this case the flap 44-1, cause a depression of the rear of the floating mobile and this dynamic support generates a wake wave pronounced from a height of between 0.50m and 1, 00m to give, again, an order of magnitude.

La longueur de la corde 50 est telle que, une fois déroulée, le pratiquant 28 surfeur se trouve au pic de la vague de sillage dès que la vague est générée. Le pratiquant est alors lancé, donc il est déjà à la vitesse de propagation de la vague et peut lâcher le palonnier pour profiter de la poussée de la vague, librement sans lien aucun. La corde 50 s'enroule dans l'enrouleur et reste suspendue puisque la butée 54 d'enroulement maintient une longueur adéquate pour permettre au pratiquant suivant de saisir le palonnier. Figure 7C.The length of the rope 50 is such that, once unwound, the surfer practitioner is at the peak of the wake wave as soon as the wave is generated. The practitioner is then launched, so he is already at the speed of propagation of the wave and can release the rudder to enjoy the thrust of the wave, freely without any link. The rope 50 winds up in the retractor and remains suspended as the winding stop 54 maintains a proper length to allow the next practitioner to grip the rudder bar. Figure 7C .

Le palonnier pend devant les deux brins 30-1 et 30-2 du lien 30.The rudder hangs in front of the two strands 30-1 and 30-2 of the link 30.

Une fois arrivé de l'autre côté, le pratiquant 20-1 s'écarte de la vague et stoppe sa progression. Figure 7D.Once on the other side, practitioner 20-1 departs from the wave and stops his progress. Figure 7D .

La coque 40 du mobile 34 ralentit et s'enfonce dans l'eau. Les brins 30-1 et 30-2 tournent autour de la poulie correspondante. Figure 7E.The shell 40 of the mobile 34 slows down and sinks into the water. Strands 30-1 and 30-2 rotate around the corresponding pulley. Figure 7E .

Comme l'ordre de traction des brins est inversé, la coque pivote nécessairement pour que le brin 30-1 soit toujours en amont et le brin 30-2 en aval.As the order of traction of the strands is reversed, the shell necessarily pivots so that the strand 30-1 is always upstream and the strand 30-2 downstream.

Le mobile 34 reprend sa vitesse et génère une nouvelle fois une vague de sillage prononcée, dans le sens inverse, suivant la même direction D. The mobile 34 resumes its speed and again generates a wake wave pronounced, in the opposite direction, in the same direction D.

La rotation des brins 30-1 et 30-2 autour de la poulie a été précédée de celle de la corde 50 avec son palonnier 48 qu'un deuxième pratiquant 28-2 a pu saisir. Figure 7F.The rotation of the strands 30-1 and 30-2 around the pulley was preceded by that of the rope 50 with its rudder 48 that a second practitioner 28-2 was able to grasp. Figure 7F .

Le deuxième pratiquant 28-2 est à son tour entraîné grâce à la corde 50, après déroulement de celle-ci en dehors de l'enrouleur. Figure 7G.The second practitioner 28-2 is in turn trained by the rope 50, after unrolling it outside the reel. Figure 7G .

Dès que la vague est à son amplitude maximale ou du moins dès qu'elle génère une puissance suffisante, le pratiquant 28-2 lâche le palonnier et profite à son tour de la poussée de la vague. Figure 7H.As soon as the wave is at its maximum amplitude or at least when it generates sufficient power, the 28-2 practitioner releases the rudder and in turn benefits from the thrust of the wave. Figure 7H .

Il est ainsi possible de pratiquer la vague dans un sens et dans l'autre de la direction D. It is thus possible to practice the wave in one direction and the other direction D.

De façon à faciliter le fonctionnement, il est prévu de nombreuses variantes et perfectionnements.In order to facilitate the operation, numerous variants and improvements are provided.

Ainsi, pour améliorer le confort de mise en place des pratiquants, il est possible d'installer une motorisation équipée d'un variateur de vitesse de rotation de façon à ralentir à proximité de chaque poulie, pendant la rotation autour de ladite poulie, jusqu'à la sortie du lien 30 de la zone de la poulie.Thus, to improve the comfort of installation of the practitioners, it is possible to install a motor equipped with a speed variator to slow down near each pulley, during the rotation around said pulley, until at the exit of the link 30 of the zone of the pulley.

Ce ralentissement peut aussi permettre une rotation plus aisée de la coque 40 du mobile 34. De même, le départ du pratiquant s'effectue en accélération.This slowing can also allow easier rotation of the hull 40 of the mobile 34. Similarly, the departure of the practitioner is accelerated.

A cet effet, il est aussi possible de prévoir, de façon optionnelle, des moyens 56 d'assistance à la rotation de la coque 40, voir figure 4. Cette assistance à la rotation se présente sous la forme d'un safran 58 fixe disposé à l'avant de la coque, orienté par rapport à la direction D de déplacement. Lorsque la coque est déjaugée et tractée par le lien 30, le safran 58 est émergé, au-dessus de la surface. Dès que la coque n'est plus tractée et s'enfonce en reprenant une position sensiblement horizontale, le safran 58 pénètre dans l'eau formant gouvernail. L'avant de la coque est soumis à rotation suivant l'orientation du safran 58 fixe. Voir l'agencement sur la figure 4.For this purpose, it is also possible to provide, optionally, means 56 for assisting the rotation of the shell 40, see figure 4 . This assistance to the rotation is in the form of a fixed rudder 58 disposed at the front of the hull, oriented relative to the direction D of displacement. When the hull is unloaded and pulled by the link 30, the saffron 58 is emerging, above the surface. As soon as the hull is no longer towed and sinks in a substantially horizontal position, the rudder 58 enters the water forming rudder. The front of the hull is rotated according to the orientation of the fixed rudder 58. See the layout on the figure 4 .

Il est d'ailleurs possible de compléter les moyens 56 d'assistance à la rotation par un second safran 60 à l'arrière de la coque 40 du mobile 34. Dans ce cas, ledit second safran 60 doit être orientable car il est constamment immergé. Il est, suivant un mode de réalisation, monté pivotant sur un axe de rotation et muni d'un moyen de rappel suivant une orientation déterminée, conjuguée de celle du premier safran lorsqu'il y en a un, pour imprimer une rotation dans le même sens.It is also possible to complete the means 56 for assisting the rotation by a second rudder 60 at the rear of the hull 40 of the mobile 34. In this case, said second rudder 60 must be adjustable because it is constantly immersed . It is, according to one embodiment, pivotally mounted on an axis of rotation and provided with a return means in a determined orientation, conjugated with that of the first saffron when there is one, to print a rotation in the same direction.

Lorsque le mobile se déplace, la traction du câble et la vitesse conférée sont très supérieures à la force dudit moyen de rappel, le safran se positionnant dans la direction D de déplacement. Le safran est rappelé en position de rotation, c'est-à-dire la position orientée, dès lors que la vitesse diminue.When the mobile moves, the traction of the cable and the speed conferred are much greater than the force of said return means, the rudder being positioned in the direction D of displacement. Saffron is recalled in the rotational position, that is to say the oriented position, as the speed decreases.

Suivant une variante de l'invention, il peut être utile d'adjoindre au volet 44-1 arrière de l'aileron 44, un volet 44-2 avant pour maintenir l'avant également vers le bas avec une incidence parfaitement ajustée. On gère ainsi un équilibre de la coque pour régler aisément la position d'attaque du plan d'eau. L'agencement suivant la présente invention permet de générer au moins une vague, d'un seul côté mais de façon avantageuse, il est possible de générer deux vagues avec un agencement symétrique du mobile 34. Ces vagues sont alors symétriques si bien que deux pratiquants peuvent surfer simultanément, choisissant l'un la droite et l'autre la gauche. Ceci permet de mieux rentabiliser l'installation du point de vue économique mais aussi d'organiser des compétitions en parallèle ou de faire partir deux pratiquants sur deux engins flottants différents.According to a variant of the invention, it may be useful to add to the flap 44-1 rear of the fin 44, a flap 44-2 forward to hold the front also down with a perfectly adjusted incidence. A balance of the hull is thus managed to easily adjust the attack position of the body of water. The arrangement according to the present invention makes it possible to generate at least one wave, on one side but advantageously, it is possible to generate two waves with a symmetrical arrangement of the mobile 34. These waves are then symmetrical so that two practitioners can surf simultaneously, choosing one the right and the other the left. This makes it possible to make the installation more profitable from an economic point of view but also to organize competitions in parallel or to send two practitioners on two different floating machines.

La corde devant être saisie par les pratiquants, un gainage sur la partie située en dessous de la butée 54 d'enroulement permet de raidir la corde et de guider la corde pendant sa rotation autour de la poulie. Une rampe de guidage, non représentée et dépendant de la géométrie de l'installation, fait pivoter la corde sous la poulie et l'écarte du passage ultérieur du lien 30, mettant le ou les palonniers à disposition du ou des pratiquants.The rope to be grasped by the practitioners, a sheathing on the part below the winding stop 54 makes it possible to stiffen the rope and to guide the rope during its rotation around the pulley. A guide bar, not shown and depending on the geometry of the installation, rotates the rope under the pulley and away from the subsequent passage of the link 30, putting the rudder or pedals available to the practitioner.

Un autre perfectionnement consiste à prévoir sur le ponton ou la base de démarrage, une rampe de départ avec des rouleaux en mousse ou en élastomère souple de façon à ce que le pratiquant sur sa planche puisse prendre un départ aisé, sans frottement. Il est rappelé que contrairement au wakeboard et au ski nautique, le surf se pratique sans strap ni chausse, juste avec l'appui du propre poids du pratiquant et une surface de planche présentant du grip sous les pieds dudit pratiquant.Another improvement is to provide on the pontoon or the starting base, a starting ramp with rollers of foam or flexible elastomer so that the practitioner on his board can take an easy start, without friction. It is reminded that unlike wakeboarding and skiing nautical surfing is practiced without straps or shoes, just with the support of the weight of the practitioner and a board surface with grip under the feet of the practitioner.

Un bac ouvert avec un revêtement moquette du type gazon artificiel, éventuellement arrosé d'eau peut permettre aussi un départ sans frottement.An open tank with a carpeting artificial lawn type, possibly sprinkled with water can also allow a start without friction.

Le mobile 34 est en amont du surfeur et le pratiquant est sur la vague en aval du mobile et de la coque. Néanmoins, afin de prévenir tout risque de blessure du pratiquant par un contact avec la coque, au moins la partie émergée de l'arrière de la coque 40 est recouverte d'un revêtement de protection tel qu'une mousse à haute densité.The mobile 34 is upstream of the surfer and the practitioner is on the wave downstream of the mobile and the hull. Nevertheless, to prevent any risk of injury to the practitioner by contact with the shell, at least the raised portion of the rear of the shell 40 is covered with a protective coating such as a high density foam.

Selon une variante particulière de réalisation, il est possible de prévoir plusieurs pylônes et poulies pour faire décrire au câble 24 moteur en boucle fermée une courbe. La vague générée est alors dissymétrique avec une vague plus fermée et une vague plus ouverte.According to a particular variant embodiment, it is possible to provide a plurality of pylons and pulleys for describing the cable 24 motor closed loop a curve. The generated wave is then asymmetrical with a more closed wave and a more open wave.

Sur la figure 8, on a représenté une variante de réalisation comportant un mobile 134 qui est totalement symétrique.On the figure 8 , there is shown an alternative embodiment comprising a mobile 134 which is completely symmetrical.

Pour ce mode de réalisation, les références numériques concernant les éléments identiques des variantes précédentes sont conservées mais en y ajoutant une centaine.For this embodiment, the numerical references relating to the identical elements of the preceding variants are retained but adding a hundred.

L'installation 100 comprend toujours deux poulies 120 associées à chaque pylône 114 dont une poulie 120-1 au moins est motrice, entraînée en rotation par une motorisation 122 électrique et une poulie 120-2 de tension, montée sur l'autre pylône, poulies 120 entre lesquelles est disposé, de façon connue, un câble 124 moteur, en boucle fermée.The installation 100 always comprises two pulleys 120 associated with each pylon 114 of which at least one pulley 120-1 is driven, driven in rotation by an electric motor 122 and a pulley 120-2 of tension, mounted on the other pylon, pulleys 120 between which is disposed, in known manner, a motor cable 124, closed loop.

De façon à reprendre les efforts de traction, il est disposé en partie supérieure un câble 121 porteur, dont les extrémités sont tendues directement entre les deux pylônes 114.In order to take up the tensile forces, a carrier cable 121 is disposed at the top, the ends of which are stretched directly between the two pylons 114.

Un chariot 123 est monté mobile en translation, par exemple par roulage sur ledit câble 121 porteur.A carriage 123 is mounted to move in translation, for example by rolling on said carrier cable 121.

Ce chariot 123 mobile est entraîné en translation par le câble 124 moteur auquel est solidarisée l'extrémité supérieure du lien 130 de traction du mobile 134.This mobile carriage 123 is driven in translation by the motor cable 124 which is secured to the upper end of the linkage 130 of the mobile 134.

Les moyens 136 de reprise des efforts comprennent dans ce mode de réalisation un seul et unique point 138 d'attache du lien 130 de traction, ménagé en partie centrale du mobile 134.The effort recovery means 136 comprise in this embodiment a single point 138 of attachment of the link 130 of traction, formed in the central part of the mobile 134.

La motorisation 122 électrique est, dans ce cas, équipée d'un variateur et d'un inverseur de façon à faire faire au chariot 123 mobile des allers/retours. Le chariot comporte donc des moyens d'arrêt liés au pilotage du moteur et en sécurité supplémentaire, il est possible de prévoir des butées mécaniques, à même les câbles, prévenant tout abordage accidentel d'un des pontons par ledit mobile.The electric motor 122 is, in this case, equipped with a variator and an inverter so as to make the carriage 123 moving back and forth. The carriage therefore comprises stop means related to the engine control and additional safety, it is possible to provide mechanical stops, the same cables, preventing any accidental boarding of one of the pontoons by said mobile.

La coque 140 est construite de façon identique, creuse, pour assurer la flottabilité, de façon préférentielle à volume fermé.The shell 140 is constructed identically, hollow, to provide buoyancy, preferably to closed volume.

De la même façon, on peut prévoir un ballastage et/ou un lestage, ceci de façon adaptée pour obtenir l'incidence recherchée pour générer la vague souhaitée.In the same way, it is possible to provide a ballast and / or a ballast, this in a manner adapted to obtain the desired impact to generate the desired wave.

Sur la figure 9, il est prévu des moyens 146 de lancement à perche du pratiquant surfeur, associés au mobile 134 et comprenant à chaque extrémité au moins une perche 146-0 et de préférence deux perches, soit quatre perches au total, munies chacune de moyens de mise à disposition.On the figure 9 , there is provided means 146 for launching the surfer practitioner, associated with the mobile 134 and comprising at each end at least one pole 146-0 and preferably two poles, four poles in total, each provided with means for setting disposition.

Selon un mode de réalisation particulier, également adaptable au mobile 34 du mode de réalisation précédent, en lieu et place des moyens 46 de lancement précédents.According to a particular embodiment, also adaptable to the mobile 34 of the previous embodiment, instead of the previous launching means 46.

De tels moyens 146 de lancement à perche comprennent une perche 146-0, un support 146-1 comprenant deux flasques 146-2 et un axe 146-3 transversal, horizontal, et donc perpendiculaire à la direction D. La perche est montée par une extrémité à rotation autour de l'axe 146-3. La au moins une perche 146-0 pivote donc dans un plan sensiblement vertical passant par la direction D.Such pole-launching means 146 comprise a pole 146-0, a support 146-1 comprising two flanges 146-2 and a transverse axis 146-3, horizontal, and therefore perpendicular to the direction D. The pole is mounted by one end rotated around the axis 146-3. The at least one pole 146-0 thus pivots in a substantially vertical plane passing through the direction D.

Des moyens 146-4 de rappel, intégrés ou indépendants de la au moins une perche, par exemple sous forme d'un ressort de rappel, ramènent ladite au moins une perche en position inclinée vers le haut, par exemple avec un angle de 45° vers le haut, l'inclinaison maximale étant déterminée par une butée 146-5.146-4 return means, integrated or independent of the at least one pole, for example in the form of a return spring, bring said at least one pole in an upwardly inclined position, for example with a 45 ° angle upwards, the maximum inclination being determined by a stop 146-5.

Les moyens 146 de lancement sont complétés par des moyens 146-6 d'abaissement de la au moins une perche 146-0, solidaires du ponton.The launching means 146 are completed by means 146-6 for lowering the at least one pole 146-0, integral with the pontoon.

Ces moyens 146-6 d'abaissement de la au moins une perche comprennent un guide 146-7, en l'occurrence solidaire du ponton, sous forme d'un tube 146-8 coudé, apte à abaisser ladite au moins une perche de la position relevée à une position abaissée à hauteur de ceinture d'homme pour donner un ordre d'idée, c'est-à-dire sensiblement horizontale.These means 146-6 for lowering the at least one pole comprise a guide 146-7, in this case secured to the pontoon, in the form of a bent tube 146-8, capable of lowering said at least one pole of the position raised to a lowered position at waist height man to give an order of idea, that is to say substantially horizontal.

Avantageusement, afin que le déplacement soit déporté, chaque perche est équipée d'un doigt 146-9 de guidage déporté afin de venir sous ledit tube 146-8 coudé des moyens 146-6 d'abaissement.Advantageously, so that the displacement is offset, each pole is equipped with a remote guide pin 146-9 in order to come under said tube 146-8 bent means 146-6 lowering.

Cet agencement est avantageux car chaque perche est escamotée lorsque le pratiquant 128, en l'occurrence 128-1/128-2, relâche ladite perche, libérant ainsi l'espace d'évolution du pratiquant surfeur pratiquant sur la vague. La perche s'escamote dès le départ, en l'absence de pratiquant et en cas de lâcher par ledit pratiquant dès le ponton.This arrangement is advantageous because each pole is retracted when the practitioner 128, in this case 128-1 / 128-2, releases said pole, thereby freeing the surfer practitioner's space of practice on the wave. The pole retracts from the beginning, in the absence of a practitioner and in case of release by said practitioner from the pontoon.

La perche 146-0 vient à basse hauteur pour une saisie facile par le pratiquant sur le ponton, quelle que soit sa taille.Pole 146-0 comes at a low height for easy entry by the practitioner on the pontoon, whatever its size.

Chaque perche peut aussi se relever, relativement au mobile, lorsque le mobile amorce le démarrage et s'incline avec la poupe qui s'enfonce, si bien que le pratiquant surfeur est libre de se lancer comme il veut, la perche est toujours au niveau nécessaire dicté par le pratiquant tant qu'il reste accroché aux moyens 146 de lancement.Each pole can also get up, relative to the mobile, when the mobile starts the boot and tilts with the stern which sinks, so that the surfer practitioner is free to launch as he wants, the pole is always at the level necessary dictated by the practitioner as long as he remains attached to the means of launch.

Chaque perche peut aussi être utilement munie d'un palonnier 148 solidaire d'un lien court fixé sur l'extrémité de chaque perche.Each pole can also be usefully provided with a rudder 148 secured to a short link fixed on the end of each pole.

Le pratiquant est ainsi autonome dans sa gestion du lancement et maître de sa position par rapport à la vague, offrant un degré de liberté de plus, avant de lâcher.The practitioner is thus autonomous in his management of the launch and master of his position relative to the wave, offering a degree of freedom more, before letting go.

Il est à noter que cet agencement est également très fiable car le nombre de pièces en jeu est très faible et peu coûteux du fait du recours à des pièces du commerce.It should be noted that this arrangement is also very reliable because the number of parts involved is very low and inexpensive because of the use of commercial parts.

Il n'est pas dangereux puisqu'il est lié au mobile et que le mobile présente toutes les garanties d'arrêt à distance du ponton.It is not dangerous since it is related to the mobile and the mobile has all the guarantees of remote shutdown of the pontoon.

Sur les figures 10, on a représenté la vague 162 de sillage du mobile 134, sur laquelle on peut constater la présence de la crête.On the figures 10 the wave wave 162 of the mobile 134 is shown, on which the presence of the ridge can be seen.

On note que le sillage est clair et que la première vague est raide et se dissipe de façon à ne pas provoquer une houle résiduelle sur le plan d'eau.

  • La figure 10A montre une vague avec un mobile d'environ 3 tonnes, se déplaçant à 18 km/h, et tracté avec un angle d'assiette de 10°.
  • La figure 10B montre une vague avec un mobile d'environ 3 tonnes, se déplaçant à 18 km/h, et tracté avec un angle d'assiette de 15°.
  • La figure 10C montre une vague avec un mobile d'environ 3 tonnes, se déplaçant à 18 km/h, et tracté avec un angle d'assiette de 20°.
It is noted that the wake is clear and that the first wave is steep and dissipates so as not to cause a residual swell on the water.
  • The figure 10A shows a wave with a mobile of about 3 tons, moving at 18 km / h, and towed with a trim angle of 10 °.
  • The figure 10B shows a wave with a mobile of about 3 tons, moving at 18 km / h, and towed with an angle of attitude of 15 °.
  • The Figure 10C shows a wave with a mobile of about 3 tons, moving at 18 km / h, and towed with a trim angle of 20 °.

La figure 11 montre la variation des hauteurs des vagues dans les conditions de variation d'assiette et de tirant d'eau dans 5 configurations 1-5.The figure 11 shows the variation of the wave heights under conditions of variation of attitude and draft in 5 configurations 1-5.

Les légendes correspondent à :

  • TE ; tirant d'eau
  • A : angle d'incidence
  • H : hauteur de vague c'est-à-dire le dénivelé entre le creux derrière le mobile et la crête de la vague de sillage.
The captions correspond to:
  • TE; Draught
  • A: angle of incidence
  • H: wave height, ie the difference in level between the hollow behind the mobile and the crest of the wake wave.

On constate que, dans le cas d'un mobile de 3 tonnes, le meilleur compromis est obtenu avec un tirant d'eau de 0,40 m, un angle d'incidence de 10° pour une même vitesse de 18km/h, ce qui conduit à une hauteur d'eau de 0,83m.It can be seen that, in the case of a 3-ton mobile, the best compromise is obtained with a draft of 0.40 m, an angle of incidence of 10 ° for the same speed of 18km / h, which leads to a water depth of 0.83m.

La hauteur d'eau est mesurée entre la crête de la vague et l'asymptote horizontale basse du creux généré derrière le mobile.The height of water is measured between the peak of the wave and the low horizontal asymptote of the hollow generated behind the mobile.

De la même façon que dans le mode de réalisation principal, il est possible d'adjoindre au moins un aileron 144 de gestion de l'assiette, non représenté. Dans le présent mode de réalisation, cet aileron serait unique, ledit aileron étant disposé en partie centrale et présentant un profil symétrique de façon à générer une action identique dans un sens de déplacement du mobile ou dans l'autre.In the same way as in the main embodiment, it is possible to add at least one fin 144 for managing the plate, not shown. In the present embodiment, this fin would be unique, said fin being disposed in central portion and having a symmetrical profile so as to generate an identical action in a moving direction of the mobile or in the other.

Un tel aileron 144 peut assurer un maintien de l'assiette avec un mobile d'un poids allégé. Ceci est un avantage intéressant car le poids peut être réduit de façon sensible, ce qui diminue l'inertie au démarrage avec pour conséquence directe de diminuer la puissance nécessaire de la motorisation 122 électrique. En effet, une fois le mobile 134 lancé et l'inertie vaincue, la puissance nécessaire pour le déplacement diminue considérablement.Such a fin 144 can maintain the trim with a mobile weight lightened. This is an interesting advantage because the weight can be reduced significantly, which reduces the inertia at startup with the direct consequence of reducing the power required of the motor 122 electric. Indeed, once the mobile 134 launched and the defeated inertia, the power required for the movement decreases considerably.

Il est possible de réaliser des agencements parfaitement équivalents aux deux modes de réalisation présentés par de simples modalités constructives, sans changer l'esprit même de l'invention.It is possible to achieve arrangements perfectly equivalent to the two embodiments presented by simple construction methods, without changing the very spirit of the invention.

C'est ainsi que l'installation peut comporter en lieu et place de deux poulies 120 associées à chaque pylône 114 non plus une poulie motrice, entraînée en rotation par une motorisation électrique et une poulie de tension, montée sur l'autre pylône, avec un câble moteur, en boucle fermée, un agencement avec deux moteurs avec chacun un enrouleur de câble. Ainsi l'un des moteurs enroule le câble pendant que l'autre libre en rotation libère le câble.Thus, the installation may comprise instead of two pulleys 120 associated with each pylon 114 no longer a driving pulley, driven in rotation by an electric motor and a tension pulley, mounted on the other pylon, with a motor cable, closed loop, an arrangement with two motors each with a cable reel. Thus one of the motors winds the cable while the other freely rotating releases the cable.

Les poulies motrices peuvent tourner autour d'un axe horizontal ou vertical.Driving pulleys can rotate around a horizontal or vertical axis.

Le câble 121 porteur de la seconde version ainsi que le chariot 123 peuvent être supprimés et le lien 130 est alors solidarisé directement au câble 124 de traction, comme dans la première variante.The carrier cable 121 of the second version and the carriage 123 can be removed and the link 130 is then secured directly to the cable 124 traction, as in the first variant.

Le guide 146-7 peut aussi être solidarisé au un câble porteur dans le second mode de réalisation.The guide 146-7 can also be secured to a carrier cable in the second embodiment.
