Description

L'invention concerne un dispositif et un système de propulsion d'un passager pour que ce dernier puisse se mouvoir dans les airs ou au sein d'un fluide avec de très grandes libertés de mouvements grâce à son agilité et son physique.The invention relates to a device and a propulsion system of a passenger so that the latter can move in the air or in a fluid with very great freedom of movement thanks to its agility and its physics.

L'invention prévoit en outre que le système soit très simple à mettre en oeuvre et accessible au plus grand nombre.The invention further provides that the system is very simple to implement and accessible to the greatest number.

Se déplacer dans l'espace a toujours été au centre des rêves de l'Homme. De nombreuses machines ont été élaborées toutes plus sophistiquées les unes que les autres pour atteindre avec plus au mois de succès ce rêve.Moving in space has always been at the center of man's dreams. Many machines have been developed, all more sophisticated than the others, to reach with more success this dream.

Ainsi pour tenter de se mouvoir avec aisance dans des environnements aussi divers qu'à la surface de l'eau ou au contact d'un environnement parfois hostile, un dispositif de propulsion tel que décrit dans les années soixante dans les documents US 3,243,144 ou US 3,381,917 comporte un corps sous la forme d'un harnais ou d'un siège contre lequel ou dans lequel un passager peut prendre place. Un tel corps coopère avec un groupe de poussée sous la forme notamment d'une paire de tuyères pour éjecter un fluide sous pression et ainsi générer une force de poussée. Pour simplifier le vol du passager et en diminuer l'effort physique, les tuyères sont disposées au dessus du centre de gravité de l'ensemble corps-passager, plus précisément au niveau des épaules du passager. Le groupe comporte en outre une station de compression d'un fluide alimentée en gaz ou en liquides inflammables et positionnée dans le dos du passager. Cette station est apte à délivrer suffisamment de poussée pour provoquer le décollage du passager transformé en quelque sorte en une fusée humaine. La faible autonomie couplée à la dangerosité de tels dispositifs ont maintenu ceux-ci dans une relative confidentialité.So to try to move with ease in environments as diverse as the surface of the water or in contact with a sometimes hostile environment, a propulsion device as described in the sixties in the documents US 3,243,144 or US 3,381,917 has a body in the form of a harness or seat against which or in which a passenger may sit. Such a body cooperates with a thrust unit in the form in particular of a pair of nozzles for ejecting a fluid under pressure and thus generating a thrust force. To simplify the flight of the passenger and reduce physical effort, the nozzles are disposed above the center of gravity of the body-passenger, more precisely at the shoulders of the passenger. The group further comprises a fluid compression station fed with flammable gases or liquids and positioned in the passenger's back. This station is able to deliver enough thrust to cause the takeoff of the passenger transformed in some way into a human rocket. Low autonomy coupled with dangerousness such devices have maintained these in a relative confidentiality.

Plus récemment, un dispositif tel que décrit dans les documents US 7,258,301 ou US 2008/0014811 A1 s'inspire de cet enseignement en l'adaptant pour réduire la dangerosité du système. La station de compression est à présent distante et généralement dédiée. En outre, le fluide sous pression est de l'eau comprimée par ladite station, s'inspirant en cela notamment d'expériences visant à exploiter de l'eau comprimée pour diminuer l'effort physique d'un plongeur sous-marin comme le suggère le document US 3,277,858 . Les documents US 7,258,301 ou US 2008/0014811 A1 proposent ainsi un dispositif de propulsion aérien similaire à son ainé adapté de sorte que de l'eau sous pression soit acheminée depuis une station de compression distante au moyen d'un conduit d'alimentation tel qu'une lance à incendie. La configuration des tuyères ainsi que les moyens permettant d'orienter lesdites tuyères pour déterminer la trajectoire du dispositif sont volontairement conservés pour maintenir une certaine facilité de pilotage du passager. Les phases de décollage notamment nécessitent toutefois une position initiale du passager en station debout, les pieds sur un support solide. L'effort physique du passager réduit à sa plus simple expression pour se mouvoir vient au détriment de la liberté et de la variété des mouvements et des déplacements à la surface de l'eau voire sous la surface de celle-ci. En outre un tel système « dispositif + station » selon US 7,258,301 présente un coût élevé lié à la conception du dispositif comportant des tuyères articulées et à la conception d'une station de compression dédiée. Le fait de pouvoir se déplacer dans l'espace présentent en soi un côté ludique. Toutefois, la configuration des tuyères situées au dessus du centre de gravité du dispositif donne l'impression au passager d'être suspendu au niveau des épaules par un crochet de grue virtuel et prive ainsi celui-ci de nombreuses sensations : chutes, figures de styles improvisées ou acrobatiques. Par ailleurs, la variété des directions et des déplacements est limitée. Il n'est pas facile par exemple de se mouvoir « en crabe » avec un dispositif connu voire de passer instantanément d'une trajectoire rectiligne à la surface de l'eau à une phase de plongée suivie de déplacements multiples sous la surface de l'eau.More recently, a device as described in the documents US 7,258,301 or US 2008/0014811 A1 is inspired by this teaching by adapting it to reduce the danger of the system. The compression station is now remote and usually dedicated. In addition, the fluid under pressure is water compressed by said station, inspired in this particular by experiments to exploit compressed water to reduce the physical effort of a submarine diver as suggested the document US 3,277,858 . The documents US 7,258,301 or US 2008/0014811 A1 thus propose an air propulsion device similar to its elder adapted so that water under pressure is conveyed from a remote compression station by means of a supply duct such as a fire hose. The configuration of the nozzles and the means for orienting said nozzles to determine the trajectory of the device are deliberately retained to maintain a certain ease of piloting the passenger. The takeoff phases in particular, however, require an initial position of the passenger while standing, feet on a solid support. The physical effort of the passenger reduces to its simplest expression to move comes at the expense of freedom and the variety of movements and displacements on the surface of the water or even under the surface of it. In addition, such a "device + station" system according to US 7,258,301 presents a high cost related to the design of the device comprising articulated nozzles and the design of a dedicated compression station. The fact of being able to move in space presents in itself a playful side. However, the configuration of the nozzles located at above the center of gravity of the device gives the impression of the passenger to be suspended at the level of the shoulders by a virtual crane hook and thus deprived him of many sensations: falls, figures of improvised or acrobatic styles. In addition, the variety of directions and movements is limited. It is not easy for example to move "crab" with a known device or even to instantly move from a straight path on the surface of the water to a diving phase followed by multiple displacements under the surface of the water.

L'invention permet de répondre à l'ensemble des inconvénients soulevés par les solutions connues. L'invention consiste principalement à prévoir un dispositif dont la conception vient en rupture au regard de l'art antérieur. Un tel dispositif comporte principalement une plateforme sensiblement plane sur laquelle prend place un ou plusieurs passagers. Le décollage et les déplacements sont générées par une force de poussée délivrée par un ensemble d'au moins trois tuyères dont deux sont libres et destinées à être tenues par l'un des passagers, lesdites tuyères étant toutes agencées pour être positionnées en dessous du centre de gravité de l'ensemble « dispositif-passager(s) ». C'est donc grâce à leur physique et à leur agilité que les passagers de ce dispositif innovant parviennent à maîtriser la poussée du dispositif et à réaliser des déplacements, des acrobaties avec une très grande liberté et un côté ludique inégalés.The invention makes it possible to meet all the disadvantages raised by the known solutions. The invention consists mainly in providing a device whose design breaks with the prior art. Such a device comprises mainly a substantially flat platform on which takes place one or more passengers. Takeoff and displacements are generated by a thrust force delivered by a set of at least three nozzles, two of which are free and intended to be held by one of the passengers, said nozzles being all arranged to be positioned below the center of gravity of the set "device-passenger (s)". It is therefore thanks to their physicality and their agility that the passengers of this innovative device manage to control the thrust of the device and to perform displacements, acrobatics with a great freedom and an unparalleled playful side.

Pour offrir à un grand nombre d'usagers de telles sensations, l'invention prévoit la possibilité d'utiliser des véhicules nautiques à moteur (VNM) connus en guise de station de compression distante. L'invention ne requiert pas une conception de stations de compression dédiées.To offer a large number of users such sensations, the invention provides the possibility of using motorized watercraft (VNM) known as a remote compression station. The invention does not require a design of dedicated compression stations.

Parmi les nombreux avantages apportés par l'invention, nous pouvons mentionner que l'invention permet :

  • de mettre à la disposition des utilisateurs un dispositif très ludique qui après apprentissage devient facile à utiliser proposant une large variété d'applications ;
  • de minimiser à leur plus simple expression les éléments nécessaires à la fabrication du dispositif de propulsion ;
  • d'utiliser des véhicules nautiques à moteur voire terrestres pour délivrer le fluide sous pression nécessaire à la poussée du dispositif ;
  • d'offrir la capacité de décoller ou de plonger à partir de toutes conditions totalement ou partiellement immergé, depuis de la terre ferme, etc. ;
  • de proposer des applications ludiques (joutes, acrobaties, etc.), de sécurité civiles ou militaires.
Among the many advantages provided by the invention, we can mention that the invention allows:

A cette fin, il est prévu tout d'abord un dispositif de propulsion comportant un corps agencé pour accueillir un passager et coopérant avec un groupe de poussée alimenté en un fluide sous pression. Pour solliciter le physique et l'agilité dudit passager, le corps comporte une plateforme sensiblement plane présentant une face inférieure et une face supérieure sur laquelle peut prendre place un passager. L'invention prévoit en outre que le groupe de poussée consiste en :

  • au moins une tuyère principale coopérant avec la face inférieure de la plateforme et étant orientée suivant un axe sensiblement perpendiculaire à ladite face inférieure ;
  • deux tuyères secondaires libres agencées pour être tenues par le passager lors d'une utilisation nominale du dispositif en dessous du centre de gravité de l'ensemble « dispositif-passager ».
To this end, it is first provided a propulsion device comprising a body arranged to accommodate a passenger and cooperating with a thrust unit supplied with a fluid under pressure. To solicit the physical and agility of said passenger, the body comprises a substantially flat platform having a lower face and an upper face on which a passenger can sit. The invention further provides that the thrust unit consists of:
  • at least one main nozzle cooperating with the lower face of the platform and being oriented along an axis substantially perpendicular to said lower face;
  • two free secondary nozzles arranged to be held by the passenger during a nominal use of the device below the center of gravity of the set "device-passenger".

Pour améliorer la maniabilité du dispositif selon l'invention, les tuyères peuvent être avantageusement agencées pour que la au moins une tuyère principale délivre majoritairement la force de poussée au détriment des tuyères secondaires.To improve the maneuverability of the device according to the invention, the nozzles may advantageously be arranged so that the at least one main nozzle delivers the thrust force to the detriment of the secondary nozzles.

Pour alimenter le dispositif en fluide sous pression, un mode de réalisation, un dispositif de propulsion selon l'invention peut comporter des moyens pour collecter et distribuer le fluide sous pression aux tuyères, moyens agencés pour connecter au dispositif un conduit d'alimentation de fluide.To supply the device with fluid under pressure, an embodiment, a propulsion device according to the invention may comprise means for collecting and delivering the fluid under pressure to the nozzles, means arranged to connect a fluid supply conduit to the device. .

Selon ce mode de réalisation, pour éviter de contraindre ledit conduit selon les déplacements du dispositif, les moyens pour collecter et distribuer peuvent présenter une base à laquelle est connecté ledit conduit d'alimentation permettant une rotation libre dudit conduit d'alimentation autour d'une axe sensiblement parallèle à celui du conduit.According to this embodiment, in order to avoid constraining said duct according to the displacements of the device, the means for collecting and distributing may have a base to which said supply duct is connected, allowing free rotation of said supply duct around a duct. axis substantially parallel to that of the conduit.

De la même manière, lesdits moyens pour collecter et distribuer peuvent présenter un bras agencé pour coopérer avec l'une des au moins une tuyère principale et lui délivrer un fluide sous pression collecté depuis la base tout en permettant une rotation libre autour d'un axe sensiblement parallèle à celui-ci dudit bras.In the same way, said means for collecting and distributing may have an arm arranged to cooperate with one of the at least one main nozzle and deliver a fluid under pressure collected from the base while allowing free rotation about an axis substantially parallel thereto of said arm.

Pour faciliter l'équilibre du passager sur la plateforme d'un dispositif selon l'invention, ce dernier peut comporter des moyens pour assurer le maintien du passager sur la face supérieure de la plateforme.To facilitate the balance of the passenger on the platform of a device according to the invention, the latter may comprise means for ensuring the keeping the passenger on the upper face of the platform.

De la même manière pour aider le passager à maitriser les tuyères secondaires, l'invention prévoit qu'un dispositif puisse comporter des moyens pour contraindre les tuyères secondaires au niveau des avant-bras du passager.In the same way to help the passenger master the secondary nozzles, the invention provides that a device may include means for constraining the secondary nozzles at the forearm of the passenger.

Pour que le passager maîtrise davantage le dispositif de propulsion et réaliser certains changements de trajectoires, un dispositif de propulsion selon l'invention peut comporter des moyens pour piloter la puissance de compression de fluide d'une station de compression délivrant le fluide sous pression.In order for the passenger to be more in control of the propulsion device and to make certain changes of trajectory, a propulsion device according to the invention may comprise means for controlling the fluid compression power of a compression station delivering the fluid under pressure.

Pour proposer des applications ludiques - du type joute ou arrosage - ou des applications par exemple liées à la lutte contre les incendies, un dispositif peut en outre comporter des moyens coopérant avec la plateforme ou le passager pour projeter un second fluide sous pression.To provide playful applications - jousting or watering type - or applications for example related to firefighting, a device may further comprise means cooperating with the platform or the passenger to project a second fluid under pressure.

Pour protéger les éléments du dispositif positionnés sous la face inférieure de la plateforme lorsque le dispositif est en contact avec le sol ou avec tout autre environnement solide voire pour influer sur la flottabilité du dispositif, ce dernier peut en outre comporter des moyens saillants coopérant avec la plateforme et étant agencés pour prévenir un choc ou un contact direct entre la face inférieure de la plateforme et l'environnement proche non fluide de ladite face inférieure.To protect the elements of the device positioned under the underside of the platform when the device is in contact with the ground or with any other solid environment or to affect the buoyancy of the device, the latter may further comprise projecting means co-operating with the platform and being arranged to prevent shock or direct contact between the underside of the platform and the near non-fluid environment of said lower face.

Pour offrir au passager d'un dispositif de propulsion conforme à l'invention une grande liberté de prestation, le dispositif peut comporter des moyens pour piloter la puissance de compression de fluide d'une station de compression délivrant le fluide sous pression.In order to offer the passenger of a propulsion device according to the invention a great freedom of performance, the device may comprise means for controlling the fluid compression power of a compression station delivering the fluid under pressure.

D'autres caractéristiques et avantages apparaîtront plus clairement à la lecture de la description qui suit et à l'examen des figures qui l'accompagnent parmi lesquelles :

  • la figure 1 présente un dispositif de propulsion conforme à l'invention ;
  • la figure 2 décrit une variante de réalisation d'une plateforme d'un dispositif de propulsion conforme à l'invention ;
  • la figure 3 décrit un mode de réalisation modulaire d'un conduit d'alimentation en fluide sous pression pour dispositif de propulsion conforme à l'invention.
Other features and advantages will emerge more clearly on reading the following description and on examining the figures that accompany it, among which:
  • the figure 1 has a propulsion device according to the invention;
  • the figure 2 discloses an alternative embodiment of a platform of a propulsion device according to the invention;
  • the figure 3 discloses a modular embodiment of a pressurized fluid supply conduit for a propulsion device according to the invention.

La figure 1 présente un mode de réalisation d'un dispositif de propulsion 10 selon l'invention. Celui-ci comporte un corps principal sous la forme d'une plateforme 11 sensiblement plane. Cette plateforme présente une face supérieure 11a sur laquelle un passager 1 peut prendre place. Selon la taille de la plateforme et la puissance du dispositif, l'invention prévoit que plusieurs passagers puissent éventuellement prendre position simultanément sur la face supérieure 11a de ladite plateforme 11. La plateforme peut être avantageusement réalisée à partir d'un matériau ou de plusieurs matériaux présentant seul ou en combinaison une rigidité suffisante pour soutenir le poids du ou des passagers et prévenir ainsi toute déformation excessive. Un matériau constituant ladite plateforme peut être privilégié pour agir sur la flottabilité du dispositif lorsque celui-ci est immergé. Selon les modes de réalisation, la plateforme peut ainsi présenter une ou plusieurs cavités emplies d'air ou de vide pour améliorer la flottabilité. En variante, on pourra privilégier l'absence de vide ou de cavité voire la présence d'un lest ou d'un ballast pour faciliter un déplacement sous la surface d'un fluide. Une telle plateforme peut consister en un ou plusieurs éléments coopérant les uns avec les autres ou dissociés.The figure 1 presents an embodiment of a propulsion device 10 according to the invention. This comprises a main body in the form of a substantially flat platform 11. This platform has an upper face 11a on which a Passenger 1 can take place. Depending on the size of the platform and the power of the device, the invention provides that several passengers can possibly take position simultaneously on the upper face 11a of said platform 11. The platform can be advantageously made from a material or several materials presenting alone or in combination sufficient rigidity to support the weight of the passenger or passengers and thus prevent excessive deformation. A material constituting said platform may be privileged to act on the buoyancy of the device when it is immersed. According to the embodiments, the platform may thus have one or more cavities filled with air or vacuum to improve buoyancy. In a variant, it will be possible to favor the absence of a void or cavity, or even the presence of a ballast or a ballast to facilitate a displacement under the surface of a fluid. Such a platform may consist of one or more elements cooperating with each other or dissociated.

Le dispositif de propulsion décrit en liaison avec la figure 1 comporte un groupe de poussée coopérant avec la plateforme 11.The propulsion device described in connection with the figure 1 has a thrust group cooperating with the platform 11.

Au sens de l'invention et dans le présent document nous utilisons le terme de « tuyère » pour définir un élément de canalisation profilé, destiné à imposer à un fluide en écoulement une augmentation de vitesse. Nous pourrions également utiliser le terme de « buse » pour caractériser un tel élément. Cette augmentation de vitesse du fluide est principalement due à une différence de sections entre l'entrée et la sortie de l' élément - la section de la sortie étant plus faible que celle de l'entrée.Within the meaning of the invention and in this document we use the term "nozzle" to define a profiled pipe element, intended to impose a flow increase a speed fluid. We could also use the term "nozzle" to characterize such an element. This increase in fluid velocity is mainly due to a difference of sections between the input and the output of the element - the section of the output being smaller than that of the input.

Selon la figure 1, un tel groupe consiste en une paire de tuyères principales 12a et 12b fixées contre la face inférieure 11b de la plateforme 11. En variante, une seule tuyère principale fixée sensiblement au centre de la face inférieure 11b de la plateforme pourrait être préférée à la paire 12a, 12b. On peut ainsi augmenter le caractère ludique de l'utilisation du dispositif par un passager. De manière générale, l'invention ne serait être limitée au nombre de tuyères principales situées sous la face inférieure 11b de la plateforme 11. Le groupe de poussée comporte ainsi au moins une tuyère principale coopérant avec ladite face inférieure.According to figure 1 , such a group consists of a pair of main nozzles 12a and 12b fixed against the lower face 11b of the platform 11. Alternatively, a single main nozzle substantially fixed to the center of the lower face 11b of the platform could be preferred to the pair 12a, 12b. It is thus possible to increase the playfulness of the use of the device by a passenger. In general, the invention would not be limited to the number of main nozzles located under the lower face 11b of the platform 11. The thrust unit thus comprises at least one main nozzle cooperating with said lower face.

Ladite au moins une tuyère principale 12a, 12b, est fixée par tous moyens à la plateforme sans présenter de degré de liberté. Pour favoriser l'envol du dispositif, l'orientation de toute tuyère principale suit avantageusement un axe A de préférence sensiblement perpendiculaire à la face inférieure de la plateforme de sorte qu'une tuyère principale expulse un fluide sous pression du proche de la face inférieure 11b de la plateforme 11 vers le lointain de celle-ci. Pour accroître la maniabilité du dispositif, le groupe de poussée d'un dispositif selon l'invention peut comporter en outre deux tuyères secondaires 13a et 13b. Celles-ci sont libres et destinées à être respectivement tenues par un passager 1 au niveau des avant-bras ou des mains. L'ensemble « plateforme, groupe de poussée et passager(s) » présente un centre de gravité CG lorsque ledit ensemble est dressé verticalement tel que l'indique la figure 1. Contrairement à l'art antérieur pour lequel les tuyères du groupe de poussée sont obligatoirement positionnées au dessus dudit centre de gravité CG pour minimiser l'effort physique du passager et en simplifier les déplacements, les tuyères principales et secondaires du groupe de poussée d'un dispositif 10 conforme à l'invention sont positionnées en dessous dudit centre de gravité CG. Un passager d'un tel dispositif 10 a la tâche de positionner et orienter les tuyères secondaires 13a et 13b avec ses mains et ses bras et la ou les tuyères principales 12a et 12b en jouant avec l'inclinaison de la plateforme via ses pieds, jambes, bassin, torse pour piloter le dispositif de propulsion. L'agilité du passager ainsi que son aisance physique maximisent ainsi les sensations procurées et permettent tous déplacements, toutes trajectoires et toutes figures acrobatiques désirés ou fortuites.Said at least one main nozzle 12a, 12b is fixed by any means to the platform without having a degree of freedom. To promote the flight of the device, the orientation of any main nozzle advantageously follows an axis A preferably substantially perpendicular to the underside of the platform so that a main nozzle expels a fluid under pressure near the bottom face 11b from platform 11 to the distance of this one. To increase the maneuverability of the device, the thrust unit of a device according to the invention may further comprise two secondary nozzles 13a and 13b. These are free and intended to be respectively held by a passenger 1 at the forearms or hands. The assembly "platform, thrust group and passenger (s)" has a center of gravity CG when said assembly is erected vertically as indicated by the figure 1 . Unlike the prior art for which thrust group thrusters are necessarily positioned above said CG center of gravity to minimize the physical effort of the passenger and simplify their movements, the main and secondary thrusters of the thrust group of a device 10 according to the invention are positioned below said center of gravity CG. A passenger of such a device 10 has the task of positioning and orienting the secondary nozzles 13a and 13b with his hands and arms and the main nozzle or nozzles 12a and 12b by playing with the inclination of the platform via his feet, legs, pelvis, torso to control the propulsion device . The agility of the passenger and his physical ease maximize the sensations provided and allow all movements, all trajectories and all desired acrobatic figures or fortuitous.

Pour délivrer une force de poussée suffisante et permettre un envol puis un déplacement, le dispositif 10 comporte en outre des moyens pour collecter et distribuer un fluide sous pression (par exemple de l'eau) aux tuyères principale(s) et secondaires. Un tel fluide est préférentiellement acheminé au moyen d'un conduit d'alimentation souple 2 depuis une station de compression distante - non représentée sur la figure 1. Un tel conduit d'alimentation peut être réalisé à partir d'une manche à incendie ou de tous autres matériaux présentant la résistance nécessaire à la pression exercée par le fluide sous pression. Un conduit d'alimentation de diamètre sensiblement égal à 110 millimètres pourra avantageusement être privilégié. Un diamètre trop faible ou trop grand engendrerait une perte de force de poussée importante au regard de la capacité de compression de la station de compression. Un collecteur 14 peut ainsi présenter une base 14c à laquelle est connecté un embout 2a d'un conduit d'alimentation 2 par exemple au moyen d'une cannelure adaptée pour recevoir ledit conduit 2. Le diamètre de ladite base 14c sera adapté au diamètre de l'embout 2a du conduit d'alimentation 2. Selon la figure 1, le collecteur 14 peut présenter une forme proche d'une d'un « T » pour collecter depuis la base 14c et distribuer via des bras 14a et 14b le fluide sous pression respectivement aux tuyères principales 12a et 12b. Le collecteur 14 peut être connecté de manière rigide aux tuyères principales ou par l'intermédiaire d'un coude éventuel de liaison 15 afin d'orienter les tuyères principales selon un axe A sensiblement perpendiculaire à la face inférieure 11b de la plateforme 11. Les bras peuvent, en variante, être connectés auxdites tuyères principales - via le coude éventuel 15 - selon une liaison pivot au niveau des bras 14a et 14b. Un tel agencement permet une libre rotation r1 suivant un axe F sensiblement parallèle aux bras 14a et 14b du collecteur 14. Ainsi, ledit collecteur peut décrire une quasi libre rotation r1 autour dudit axe F, modulo la butée que représente la face inférieure 11b de la plateforme 11 lors d'une inclinaison excessive de cette dernière. Une rotation r1 relative du collecteur autour de l'axe F au regard du plan de la face inférieure de la plateforme 11, rotation consécutive de la liaison du collecteur avec le conduit d'alimentation 2, n'entraîne pas de rotation de la plateforme 11. De la même manière, l'invention prévoit que l'embout 2a du conduit d'alimentation 2 peut avantageusement coopérer avec le collecteur 14 au niveau de sa base 14c selon une liaison pivot pour permettre une libre rotation r2 autour d'un axe C sensiblement parallèle au conduit 2. Le dispositif peut ainsi librement pivoter autour dudit axe C sans engendrer de boucles ou de contraintes excessives sur le conduit d'alimentation 2.To provide a sufficient thrust force and allow flight and displacement, the device 10 further comprises means for collecting and delivering a fluid under pressure (eg water) to the main nozzles (s) and secondary. Such a fluid is preferably conveyed by means of a flexible supply duct 2 from a remote compression station - not shown on FIG. figure 1 . Such a supply duct may be made from a fire hose or any other material having the necessary resistance to the pressure exerted by the fluid under pressure. A supply duct of diameter substantially equal to 110 millimeters may advantageously be preferred. Too small or too large a diameter would cause a significant loss of thrust force with respect to the compression capacity of the compressor station. A collector 14 may thus have a base 14c to which is connected a tip 2a of a supply duct 2 for example by means of a groove adapted to receive said duct 2. The diameter of said base 14c will be adapted to the diameter of the tip 2a of the supply duct 2. According to the figure 1 the manifold 14 may have a shape close to one of a "T" to collect from the base 14c and distribute via the arms 14a and 14b the pressurized fluid respectively to the main nozzles 12a and 12b. The collector 14 can be connected rigidly to the main nozzles or via an optional connecting bend 15 in order to orient the main nozzles along an axis A substantially perpendicular to the lower face 11b of the platform 11. The arms may alternatively be connected to said main nozzles - via the optional bend 15 - in a pivot connection at the arms 14a and 14b. Such an arrangement allows a free rotation r1 along an axis F substantially parallel to the arms 14a and 14b of the collector 14. Thus, said collector can describe an almost free rotation r1 about said axis F, modulo the stop that represents the lower face 11b of the platform 11 at an excessive inclination of the latter. A relative rotation of the collector around the axis F with respect to the plane of the lower face of the platform 11, consecutive rotation of the connection of the manifold with the supply conduit 2, does not cause rotation of the platform 11 In the same way, the invention provides that the tip 2a of the supply duct 2 can advantageously cooperate with the collector 14 at its base 14c in a pivot connection to allow a free rotation r2 about a C axis substantially parallel to the duct 2. The device can thus pivot freely about said axis C without generating excessive loops or stresses on the supply duct 2.

La configuration en « T » - telle que décrite à titre d'exemple préféré en liaison avec la figure 1 - du collecteur 14 présentant une base 14c et deux bras 14a et 14b diamétralement opposés peut être bien évidemment différente dans le cas d'un dispositif 10 qui ne présenterait par exemple qu'une seule tuyère principale. Le collecteur 14 aurait dans ce cas la configuration d'un coude tel un « ┌ » pour collecter - depuis une base 14c - et délivrer - via un bras 14a - le fluide sous pression depuis le conduit d'alimentation 2 vers la tuyère principale par l'intermédiaire d'un éventuel coude de liaison 15 coopérant d'une part avec le bras du collecteur et d'autre part avec la tuyère principale. Avantageusement des liaisons pivot au niveau de la base 14c et du bras unique 14a du collecteur 14 sont avantageusement préférées pour les raisons exprimées précédemment.The "T" configuration - as described by way of a preferred example in connection with the figure 1 - Collector 14 having a base 14c and two arms 14a and 14b diametrically opposite may be obviously different in the case of a device 10 which would have such a single main nozzle. The collector 14 would have in this case the configuration of a bend such as a "┌" to collect - from a base 14c - and deliver - via an arm 14a - the pressurized fluid from the feed pipe 2 to the main nozzle through a possible connecting elbow 15 cooperating on the one hand with the collector arm and on the other hand with the main nozzle. Advantageously pivot connections at the level of the base 14c and the single arm 14a of the collector 14 are advantageously preferred for the reasons previously expressed.

Pour distribuer le fluide sous pression aux tuyères secondaires 13a et 13b, l'invention prévoit, à titre d'exemple et comme l'indique la figure 1, que des conduits secondaires 18a et 18b - sous la forme avantageuse de tuyaux souples - délivrent depuis le collecteur 14 ledit fluide sous pression aux tuyères secondaires. Pour ne pas gêner le passager 1, lesdits tuyaux secondaires peuvent être guidés le long du dos jusqu'aux épaules par l'utilisation de moyens de maintien 19 (sangles, harnais, etc.). L'invention prévoit que le dispositif offre la possibilité à un passager d'utiliser des moyens pour contraindre les tuyères secondaires au niveau de ses avant-bras. Ainsi et en liaison avec la figure 1, un ensemble 20a et 20b d'éléments comportant un corps pour coopérer avec un avant-bras et une tuyère secondaire et/ou un conduit secondaire alimentant ladite tuyère secondaire peut être fixé au moyen de sangles ou de tous autres types de fixation à chaque avant-bras du passager 1. La tenue d'une tuyère secondaire est facilitée pour le passager.In order to distribute the fluid under pressure to the secondary nozzles 13a and 13b, the invention provides, by way of example and as indicated by figure 1 , that secondary ducts 18a and 18b - in the advantageous form of flexible pipes - deliver from the collector 14 said fluid under pressure to the secondary nozzles. To avoid disturbing the passenger 1, said secondary pipes can be guided along the back to the shoulders by the use of holding means 19 (straps, harnesses, etc.). The invention provides that the device offers the possibility to a passenger to use means to constrain the secondary nozzles at its forearms. So and in connection with the figure 1 , an assembly 20a and 20b of elements comprising a body for cooperating with a forearm and a secondary nozzle and / or a secondary duct supplying said secondary nozzle may be fixed by means of straps or any other type of attachment to each before 1. The holding of a secondary nozzle is facilitated for the passenger.

L'invention prévoit en outre que la plateforme 11 puisse présenter des moyens de maintien d'un passager sur la face supérieure 11a de ladite plateforme. Ainsi selon la position préférée d'un passager sur la plateforme d'un dispositif conforme à l'invention, lesdits moyens de maintien peuvent consister - comme l'indique la figure 1 - en une paire de chaussons ou de bottes de fixation d'un type similaire à ce que l'on peut trouver par exemple dans la pratique du wakeboard. D'autres types de moyens de maintien peuvent être préférés selon que l'on souhaite aider un passager en positions jambe fléchie, à genoux voire encore assis.The invention further provides that the platform 11 may have means for holding a passenger on the upper face 11a of said platform. Thus, according to the preferred position of a passenger on the platform of a device according to the invention, said holding means may consist - as indicated by figure 1 - in a pair of slippers or fastening boots of a type similar to what can be found for example in the practice of wakeboarding . Other types of holding means may be preferred depending on whether it is desired to help a passenger leg positions flexed, kneeling or even sitting.

Pour favoriser l'envol et d'une manière générale l'utilisation d'un dispositif selon l'invention, la ou les tuyères principales ainsi que les tuyères secondaires pourront être agencées de sorte que le groupe de poussée ainsi constitué délivre en majorité une force de poussée au niveau de la ou des tuyères principales au détriment des tuyères secondaires. Pour cela, la configuration des tuyères (sections des entrées et des sorties respectives desdites tuyères) pourra être choisie pour préférentiellement délivrer de l'ordre de 80% de la force de poussée au niveau de la ou des tuyères principales. Ainsi, à titre d'exemple, une tuyère principale pourra être réalisée avec des sections d'entrée et de sortie respectives sensiblement égales à 50 et 40 millimètres de diamètre et une tuyère secondaire pourra être réalisée avec des sections d'entrée et de sortie respectives sensiblement égales à 40 et 25 millimètres de diamètre. Selon ce mode de réalisation préféré, un conduit secondaire 18a et 18b pourra avoir une section de l'ordre de 40 millimètres de diamètre. Un collecteur 14 pourra disposer quant à lui d'une section de 120 millimètres de diamètres proche de sa base et d'une section de 80 millimètres de diamètres au niveau d'un bras. La section d'un éventuel coude de liaison 15 entre une tuyère principale et un bras du collecteur peut avantageusement adapter les sections respectives du bras et de l'entrée de la tuyère. Toute autre configuration du groupe de poussée pourrait être choisie pour adapter la répartition de la force de poussée entre les tuyères principale(s) et secondaires.To promote the flight and in general the use of a device according to the invention, the main nozzle or nozzles and the secondary nozzles may be arranged so that the thrust group thus formed delivers a majority of force thrust at the main nozzle or nozzles at the expense of secondary nozzles. For this, the configuration of the nozzles (sections of the respective inlets and outlets of said nozzles) may be chosen to preferentially deliver about 80% of the thrust force at the main nozzle or nozzles. Thus, by way of example, a main nozzle may be made with respective inlet and outlet sections substantially equal to 50 and 40 millimeters in diameter and a secondary nozzle may be made with respective inlet and outlet sections. substantially equal to 40 and 25 millimeters in diameter. According to this preferred embodiment, a secondary duct 18a and 18b may have a section of the order of 40 millimeters in diameter. A collector 14 may have in turn a section of 120 millimeters in diameter near its base and a section of 80 millimeters in diameter at an arm. The section of a possible connecting bend 15 between a main nozzle and a manifold arm can advantageously adapt the respective sections of the arm and the inlet of the nozzle. Any other configuration of the thrust unit could be chosen to adapt the distribution of the thrust force between the main and secondary nozzles.

La figure 2 décrit un mode de réalisation préférée d'une plateforme 11 pour un dispositif de propulsion selon l'invention. Une telle plateforme 11 sensiblement plane présente - sur sa face supérieure 11a - deux espaces pour accueillir respectivement les pieds d'un passager représentés en pointillés. Une telle plateforme 11 est agencée de sorte que sa face inférieure 11b coopère avec des moyens saillants 17 eux-mêmes agencés pour offrir une protection aux éléments - non représentés sur la figure 2 - du dispositif situés sous la face inférieure 11b de la plateforme 11, de manière non exhaustive : la ou les tuyère(s) principale(s), les moyens pour collecter et distribuer un fluide sous pression. De tels moyens 17 peuvent ainsi matérialiser des points d'appui et constituer une cage de protection pour lesdits éléments. Tout choc intempestif ou autre contact direct entre lesdits éléments et leur environnement proche non fluide peuvent être ainsi prévenus notamment lors d'un décollage ou d'un atterrissage depuis la terre ferme voire un amerrissage depuis des eaux peu profondes.The figure 2 discloses a preferred embodiment of a platform 11 for a propulsion device according to the invention. Such a substantially flat platform 11 has - on its upper face 11a - two spaces for respectively accommodate the feet of a passenger shown in dashed lines. Such a platform 11 is arranged so that its lower face 11b cooperates with projecting means 17 themselves arranged to provide protection to the elements - not shown on the figure 2 - Of the device located under the bottom face 11b of the platform 11, non-exhaustive: the main nozzle (s) (s), the means for collecting and distribute a fluid under pressure. Such means 17 can thus materialize support points and constitute a protective cage for said elements. Any inadvertent shock or other direct contact between said elements and their near non-fluid environment can thus be prevented especially during a take-off or landing from the land or even a landing from shallow waters.

Le choix du ou des matériaux pour réaliser les moyens saillants 17 peut être dicté par le niveau de prévention de choc désiré, la résistance au poids exercé par le ou les passagers présent(s) sur la plateforme lors de phases de décollage, atterrissage ou amerrissage. Les moyens saillants 17 peuvent en outre interagir sur la flottabilité du dispositif recherchée selon leurs structure et configuration.The choice of the material or materials for producing the projecting means 17 may be dictated by the desired level of shock prevention, the resistance to weight exerted by the passenger (s) present on the platform during takeoff, landing or landing phases. . The projecting means 17 may further interact on the buoyancy of the desired device according to their structure and configuration.

Un passager d'un dispositif de propulsion conforme à l'invention peut réaliser un nombre inégalé à ce jour de déplacements (en l'air, sous la surface d'un milieu aquatique, etc.). Nous pouvons mentionner qu'un envol peut être déclenché - lors de l'alimentation en fluide sous pression dudit dispositif - si le passager tient les tuyères secondaires, bras tendus vers l'arrière de son corps, dos cambré. Un plongeon peut par exemple être commandé par ledit passager en courbant son corps tête en avant, etc.A passenger of a propulsion device according to the invention can achieve an unmatched number of movements (in the air, under the surface of an aquatic environment, etc.). We can mention that a flight can be triggered - during the supply of pressurized fluid of said device - if the passenger holds the secondary nozzles, arms stretched towards the back of his body, back arched. A dive may for example be controlled by said passenger by bending his head body forward, etc.

Pour faciliter le pilotage du passager et lui conférer une autonomie d'action accrue, l'invention prévoit qu'un dispositif de propulsion puisse comporter en outre des moyens pour piloter la puissance de la station de compression. Ainsi, en réception d'une commande délivrée par de tels moyens et véhiculée par des moyens de communication filaire ou radio adaptés, la station peut moduler la puissance de compression du fluide qu'elle délivre au dispositif de propulsion. Le passager peut ainsi commander par exemple son envol ou encore peaufiner ses déplacements en modulant la pression du fluide circulant dans le conduit d'alimentation le reliant à la station de compression.To facilitate piloting of the passenger and to give it greater autonomy of action, the invention provides that a propulsion device may further comprise means for controlling the power of the compression station. Thus, in reception of a command delivered by such means and conveyed by suitable wire or radio communication means, the station can modulate the compression power of the fluid that it delivers to the propulsion device. The passenger can thus control for example its flight or further refine its movements by modulating the pressure of the fluid flowing in the supply duct connecting it to the compressor station.

Par ailleurs, selon les applications ou utilisations d'un dispositif de propulsion conforme à l'invention, ce dernier peut en outre comporter des moyens 15 (par exemple sous la forme d'une tuyère) pour projeter un fluide sous pression distinct de celui utilisé pour mouvoir le dispositif ou dérivé de ce lui-ci. Ces moyens optionnels coopèrent avantageusement avec la plateforme 11 ou en variante avec le passager (au niveau d'une épaule, de la taille, etc.). L'objectif est ici de proposer une application de sécurité civile du type lutte contre les incendies par exemple ou encore des jeux aquatiques : arrosage de tiers, nouvelle joute où le jet du second fluide matérialise une lance non solide prévenant le risque de blessures tout en conservant sa fonction pour déstabiliser un adversaire...Furthermore, according to the applications or uses of a propulsion device according to the invention, the latter may further comprise means 15 (for example in the form of a nozzle) for projecting a fluid under pressure distinct from that used. to move the device or derived from it. These optional means advantageously cooperate with the platform 11 or alternatively with the passenger (at the level of a shoulder, the waist, etc.). The objective here is to propose a civil security application of the firefighting type, for example, or water games: third party watering, a new game where the jet of the second fluid materializes a non-solid lance preventing the risk of injury while retaining its function to destabilize an opponent ...

Un dispositif de propulsion conforme à l'invention, par exemple tel que le dispositif 10 décrit à titre d'exemple en liaison avec les figures 1 et/ou 2, peut être alimenté par toute station de compression de fluide distante à partir du moment où celle-ci est apte à délivrer un fluide dont la pression est suffisante pour le fonctionnement du dispositif de propulsion. Celle-ci peut être dédiée à cet usage au risque d'augmenter le coût global d'un système de propulsion comportant un dispositif de propulsion selon l'invention, une station de compression distante et un conduit d'alimentation coopérant avec lesdits dispositif et station pour acheminer le fluide sous pression.A propulsion device according to the invention, for example such that the device 10 described as example in connection with figures 1 and / or 2, can be powered by any remote fluid compression station from the moment when it is able to deliver a fluid whose pressure is sufficient for the operation of the propulsion device. This may be dedicated to this use at the risk of increasing the overall cost of a propulsion system comprising a propulsion device according to the invention, a remote compression station and a supply duct cooperating with said device and station for conveying the fluid under pressure.

Pour diminuer un tel coût, l'invention prévoit également que la station de compression distante puisse être un appareil dont la fonction principale originelle est différente de l'alimentation en un fluide sous pression d'un dispositif de propulsion. A titre d'exemple, l'invention prévoit qu'un véhicule de pompier terrestre ou nautique puisse être exploité en tant que station de compression distante s'il dispose d'une capacité de compression de fluide suffisante. On peut ainsi mettre à profit la capacité de compression naturelle d'un fluide d'un véhicule nautique à moteur (VNM) tel que par exemple le RUNABOUT MZR édition 2011 du constructeur ZAPATA RACING.To reduce such a cost, the invention also provides that the remote compression station may be an apparatus whose original main function is different from the supply of a fluid under pressure of a propulsion device. For example, the invention provides that a land or water fire engine can be operated as a remote compression station if it has a sufficient fluid compression capacity. It can thus take advantage of the natural compression capacity of a fluid of a motor vehicle (VNM) such as for example the RUNABOUT MZR 2011 edition of the manufacturer ZAPATA RACING.

Quelque soit la station de compression utilisée, l'invention prévoit que ladite station puisse comporter des moyens pour réguler la puissance de compression à partir d'une commande distante. Ainsi, il est possible de faire interagir les moyens pour piloter la puissance d'une station de compression éventuellement distante d'un dispositif de propulsion conforme à l'invention avec lesdits moyens pour réguler la puissance d'une station ainsi adaptée. Par l'intermédiaire de moyens de communication (filaire ou radio) pour véhiculer un signal de commande émanant du dispositif de propulsion et à destination de la station de compression, un passager dudit dispositif peut piloter à distance la puissance de la station et ainsi adapter ses déplacements réalisés avec le dispositif de propulsion.Whatever the compression station used, the invention provides that said station may comprise means for regulating the power of compression from a remote control. Thus, it is possible to make the means interact to control the power of a compression station possibly remote from a propulsion device according to the invention with said means for regulating the power of a station thus adapted. Via means of communication (wired or radio) to convey a control signal from the propulsion device and to the compressor station, a passenger of said device can remotely control the power of the station and thus adapt its movements made with the propulsion device.

Comme l'indique la figure 3, un conduit d'alimentation 2 - destiné à être connecté respectivement à un dispositif de propulsion et à une station de compression distante telle que par exemple un VNM - peut être modulaire. Il peut comporter une pluralité d'éléments 2i interconnectables au moyens de raccords 2ib ou d'embouts libres 2ia. Ainsi, il est possible de jouer sur la longueur du conduit d'alimentation 2 selon l'usage recherché. Il est possible également de relier à la demande un dispositif de propulsion auquel un premier élément de conduit 2i1 est d'hors et déjà connecté à une station de compression distante présentant une première longueur de conduit 2i2 d'alimentation pour délivrer un fluide sous pression. Le conditionnement et le transport des éléments d'un système de propulsion selon l'invention sont ainsi facilités.As the figure 3 , a supply duct 2 - intended to be connected respectively to a propulsion device and to a remote compression station such as for example a VNM - may be modular. It may comprise a plurality of elements 2i interconnectable by means of 2ib connectors or free ends 2ia. Thus, it is possible to play along the length of the supply duct 2 according to the desired use. It is also possible to connect on demand a propulsion device to which a first conduit element 2i1 is off and already connected to a remote compression station having a first length of supply conduit 2i2 for delivering a fluid under pressure. The packaging and transport of the elements of a propulsion system according to the invention are thus facilitated.

Un grand nombre d'applications ludiques ou de services civils et/ou militaires sont permises grâce à un système de propulsion conforme à l'invention. A titre d'exemple, il est possible de prévoir un VNM transportant un dispositif de propulsion et un conduit d'alimentation pour que le conducteur du VNM puisse à la demande se muer en passager du dispositif.A large number of fun applications or civil and / or military services are allowed through a propulsion system according to the invention. For example, it is possible to provide a VNM carrying a propulsion device and a supply duct so that the driver of the VNM can on request become a passenger of the device.

L'invention ne serait être limitée par les exemples d'utilisation cités.The invention would not be limited by the use examples cited.

Des accessoires pour améliorer encore le caractère ludique ou les conditions d'exploitation d'un tel système pourraient également être apportés : éclairage, moyens de navigation, etc.Accessories to further improve the playfulness or the operating conditions of such a system could also be provided: lighting, navigation means, etc.
