Description

L'invention concerne une structure pour réaliser des exercices physiques, notamment des membres inférieurs d'un(e) utilisateur/utilisatrice, de manière au moins partiellement immergée tel que par exemple dans une piscine, une rivière, l'océan, etc.The invention relates to a structure for performing physical exercises, including lower limbs of a user / user, so at least partially immersed such as for example in a pool, a river, the ocean, etc..

On connaît de nombreux types d'appareils destinés à permettre à un/une utilisateur/utilisatrice de réaliser des exercices physiques dans l'eau, ce qui, outre l'aspect ludique, permet d'augmenter l'effort pour optimiser l'exercice visant à muscler ou rééduquer.Many types of apparatus are known for allowing a user to perform physical exercises in the water, which, in addition to the playful aspect, makes it possible to increase the effort to optimize the exercise aimed at to strengthen or rehabilitate.

Un premier genre d'appareil connu est du type dit stationnaire, comportant un pédalier et une selle, et qui est destiné à être posé au fond de la piscine, ou sur le lit de la rivière ou le fond marin.A first type of known device is the so-called stationary type, including a pedal and a saddle, and which is intended to be placed at the bottom of the pool, or on the bed of the river or the seabed.

Ce genre d'appareil stationnaire, qui s'apparente en quelque sorte à une bicyclette sans roues, présente un côté ludique limité de par son caractère stationnaire et fixe.This kind of stationary apparatus, which is somewhat like a bicycle without wheels, has a playful side limited by its stationary and fixed character.

On a proposé un second type d'appareil sur lequel prend appui l'utilisateur, qui est en grande partie immergé, est pourvu d'un pédalier associé à un moyen de propulsion à déplacement hydraulique, tel qu'une hélice ou turbine. Certains de ces appareils comportent des moyens de flottaison.It has been proposed a second type of apparatus on which bears the user, which is largely immersed, is provided with a pedal associated with a propulsion means with hydraulic displacement, such as a propeller or turbine. Some of these devices include flotation means.

On peut citer par exemple à cet égard la demande de brevet EP 2 510 986 , mais dont la structure est relativement complexe et encombrante et a priori présente des difficultés de stabilisation.For example, in this respect, the patent application EP 2 510 986 , but whose structure is relatively complex and cumbersome and a priori presents stabilization difficulties.

La demande de brevet FR 2 702 443 montre un bâti flottant pourvu, à une extrémité d'une surface d'appui pour le bassin de l'utilisateur/trice, et à une autre extrémité d'une hélice reliée à un pédalier fixé au bâti. A priori, l'utilisateur/utilisatrice n'étant soutenu(e) que par son bassin, doit fournir un effort non négligeable pour maintenir la tête hors de l'eau, ce qui requiert une certaine pratique. À noter également qu'une bonne partie des jambes n'est pas immergée, limitant l'effet de résistance hydraulique.The request for FR 2,702,443 shows a floating frame provided, at one end of a bearing surface for the user's basin, and at another end of a propeller connected to a crankset fixed to the frame. A priori, the user is supported only by its pool, must provide a significant effort to keep the head out of the water, which requires some practice. Also note that a good part of the legs is not immersed, limiting the effect of hydraulic resistance.

Par ailleurs, il existe des structures flottantes sur lesquelles s'assoit l'utilisateur/utilisatrice, ce qui permet de profiter de l'élément marin ou de la piscine sans se soucier de maintenir la tête hors de l'eau. Par définition, ces structures flottantes à caractère ludique n'ont pas pour finalité, en soi, de réaliser des exercices physiques de musculation. Le brevet US 6 276 979 en montre un exemple.In addition, there are floating structures on which the user sits, which allows to enjoy the marine element or the pool without worrying to keep the head out of the water. By definition, these floating structures playfulness are not intended, in itself, to perform physical exercises of bodybuilding. The patent US 6,276,979 show an example.

Ainsi, à ce jour, il n'existe pas de structure ou d'appareil permettant de réaliser des exercices physiques de manière quasiment totalement immergée, en toute sécurité, tout en présentant le caractère ludique lié au déplacement dans l'eau.Thus, to date, there is no structure or apparatus for performing physical exercises so almost completely immersed, safely, while having the playful nature of moving in the water.

L'invention vise à proposer une telle structure ou appareil présentant les avantages mentionnés ci-dessus.The invention aims to provide such a structure or apparatus having the advantages mentioned above.

À cette fin, selon invention, la structure destinée à réaliser des exercices physiques dans un milieu liquide (piscine, rivières, océans), du type comportant :

  • au moins un élément apte à assurer la flottaison au moins partielle de l'utilisateur/utilisatrice ;
  • des moyens de propulsion hydraulique, tel qu'une hélice ou roue à aube, reliés à des moyens d'entraînement mécanique susceptibles d'être actionnés par les jambes de l'utilisateur/utilisatrice ;
  • des moyens de support ou d'appui d'au moins une partie du corps de l'utilisateur/utilisatrice ;
est caractérisée en ce que ledit élément flottant sert de support ou d'appui à au moins une partie du dos de l'utilisateur/utilisatrice, et en ce que les des moyens de propulsion hydraulique et les moyens d'entraînement mécanique d'une part sont liés de manière amovible à l'élément de flottaison.To this end, according to the invention, the structure intended for performing physical exercises in a liquid medium (pool, rivers, oceans), of the type comprising:
  • at least one element capable of ensuring at least partial flotation of the user;
  • hydraulic propulsion means, such as a propeller or impeller, connected to mechanical drive means that can be actuated by the legs of the user;
  • means for supporting or supporting at least a portion of the user's body;
is characterized in that said floating element serves to support or support at least a portion of the user's back, and that the hydraulic propulsion means and the mechanical drive means on the one hand are releasably connected to the buoyancy element.

De préférence, l'élément flottant sert de support et d'appui pour la totalité du dos de l'utilisateur/utilisatrice, et de manière encore plus préférée, également la nuque et/ou la tête de ce dernier/cette dernière.Preferably, the floating element serves as support and support for the entire back of the user / user, and even more preferably, also the neck and / or the head of the latter / the latter.

Avantageusement, l'élément flottant est constitué d'un élément tubulaire en forme de générale de U comprenant deux branches espacées et parallèles et une base transversale aux deux branches et les reliant en l'une de leurs extrémités, et dont la base transversale est apte à soutenir la nuque et/ou la tête de l'utilisateur/utilisatrice.Advantageously, the floating element consists of a generally U-shaped tubular element comprising two spaced and parallel branches and a base transverse to the two branches and connecting them at one of their ends, and whose transverse base is suitable to support the neck and / or the head of the user.

L'extrémité de chaque branche du U à l'opposé de la base dudit U est reliée, de manière préférentiellement amovible, à une première extrémité d'un longeron dont la seconde extrémité est fixée aux moyens de propulsion et aux moyens d'entraînement.The end of each leg of the U opposite the base of said U is connected, preferably detachably, to a first end of a spar whose second end is fixed to the propulsion means and to the drive means.

Les moyens de propulsion et les moyens d'entraînement sont disposés à une distance (correspondant à longueur desdits longerons) telle qu'en position d'utilisation, les jambes de l'utilisateur/trice soient à même d'actionner les moyens d'entrainement.The propulsion means and the drive means are arranged at a distance (corresponding to the length of said longitudinal members) such that in the position of use, the legs of the user are able to actuate the drive means .

Les moyens d'entraînement avantageusement sont du type pédalier, et les moyens de propulsion sont avantageusement constitués d'une turbine associée à une coque ou boitier.The drive means are advantageously of the pedal type, and the propulsion means are advantageously constituted by a turbine associated with a shell or box.

L'invention concerne en outre l'utilisation de la structure ci-dessus, sous deux formes :

  1. A) soit en position allongée de l'utilisateur/trice, et en déplacement de la structure dans l'eau, les moyens de propulsion et les moyens de d'entrainement associés étant liés à l'élément flottant qui soutient le dos de l'utilisateur/trice ;
  2. B) soit en position assise, de manière fixe sur le sol (fond de piscine ou d'océan), les moyens de propulsion et les moyens d'entrainement associés étant séparés de l'élément flottant.
The invention further relates to the use of the above structure in two forms:
  1. A) in the extended position of the user, and in displacement of the structure in the water, the propulsion means and the associated driving means being connected to the floating element which supports the back of the user;
  2. B) in a sitting position, fixedly on the ground (pool or ocean bottom), the propulsion means and the associated drive means being separated from the floating element.

Ainsi, l'invention est également relative à un ensemble pour réaliser des exercices physiques des membres inférieurs, destiné à être immergé totalement et posé sur le fond d'une piscine, ou le lit d'une rivière ou le fond de l'océan, selon l'option d'utilisation B) ci-dessus.Thus, the invention also relates to an assembly for performing physical exercises of the lower limbs, intended to be totally immersed and placed on the bottom of a pool, or the bed of a river or the bottom of the ocean, according to option of use B) above.

L'ensemble de l'invention comporte un bâti qui, d'une part est pourvu d'une assise (selle) et d'un organe de préhension tel qu'un guidon, et d'autre part sur lequel est susceptible d'être fixé, de manière amovible, la structure telle que mentionnée précédemment, et d'autres éléments permettant l'utilisation et le fonctionnement dudit ensemble.The assembly of the invention comprises a frame which, on the one hand is provided with a seat (saddle) and a gripping member such as a handlebar, and secondly on which is likely to be removably attached the structure as mentioned above, and other elements allowing the use and operation of said assembly.

Plus précisément, dans ledit ensemble :

  • l'élément flottant est disposé à l'arrière du bâti ;
  • les moyens de propulsion et les moyens d'entraînement (pédalier) sont fixés à la base et en partie avant du bâti.
More specifically, in said set:
  • the floating element is disposed at the rear of the frame;
  • the propulsion means and the drive means (pedal) are fixed at the base and at the front of the frame.

Plus précisément, l'ensemble comporte une selle réglable en hauteur et en translation horizontale, et un guidon réglable en translation horizontale et en inclinaison, et en ce que la bâti est pourvu à son extrémité avant, de moyens de roulement et à son extrémité arrière de patins.More specifically, the assembly comprises a saddle adjustable in height and in horizontal translation, and a handlebar adjustable in horizontal translation and tilt, and in that the frame is provided at its front end with rolling means and at its rear end. of skates.

Ainsi, l'invention permet de disposer en un seul dispositif, d'une part d'un ensemble permettant l'exercice physique en position assise, et de manière immergée, et d'autre part d'une structure semi flottante pour l'exercice physique, permettant de se déplacer dans l'eau, à la surface de celle-ci.Thus, the invention makes it possible to have in a single device, on the one hand, an assembly allowing the physical exercise in sitting position, and in a submerged manner, and on the other hand a semi-floating structure for exercise. physical, allowing to move in the water, on the surface of this one.

Dans la suite de la description les termes « supérieur », « inférieur », « avant », « arrière », « frontal », « proximal », « distal », « haut », « bas », sont utilisés dans le cadre d'une installation normale de la structure et de l'ensemble, par rapport à la position d'utilisation par un(e) utilisateur/trice.In the rest of the description, the terms "superior", "inferior", "front", "back", "frontal", "proximal", "distal", "up", "down" are used in the context of a normal installation of the structure and assembly, relative to the position of use by a user.

Il est fait référence aux figures 1 à 3 montrant un exemple de réalisation de la structure semi flottante de l'invention permettant de réaliser des exercices physiques des membres inférieurs, en déplacement dans un milieu liquide. Sur ces figures, la structure est représentée hors de l'eau, l'utilisateur n'étant pas montré.Reference is made to Figures 1 to 3 showing an exemplary embodiment of the semi-floating structure of the invention for performing physical exercises of the lower limbs moving in a liquid medium. In these figures, the structure is shown out of the water, the user not being shown.

La structure 1 comporte trois parties, à savoir :

  • une partie arrière formée d'un élément flottant 2 en forme générale de U ;
  • une partie avant 3 comprenant des moyens de propulsion, à déplacement hydraulique, et des moyens d'entraînement de ces derniers ;
  • une partie intermédiaire 4, en forme de U et reliant l'élément flottant 2 et la partie avant 3.
Structure 1 has three parts, namely:
  • a rear portion formed of a floating element 2 in the general shape of U;
  • a front portion 3 comprising propulsion means, hydraulic displacement, and drive means thereof;
  • an intermediate part 4, U-shaped and connecting the floating element 2 and the front part 3.

Plus précisément, l'élément flottant 2 est un élément tubulaire en un matériau tel qu'une mousse, du type par exemple « fritte » de piscine, d'un diamètre par exemple d'environ 6.5 centimètres, et une longueur d'environ 200 centimètres. L'écartement entre les extrémités avant 2A et 2B du U est de l'ordre de 70 centimètres, modifiable suivant la taille de l'utilisateur ou l'utilisatrice.More specifically, the floating element 2 is a tubular element of a material such as a foam, for example of the "sintered" pool type, of a diameter for example of about 6.5 centimeters, and a length of about 200 centimeters. The spacing between the front ends 2A and 2B of the U is of the order of 70 centimeters, modifiable according to the size of the user.

La base transversale 2C du U est destinée à servir d'appui ou de support pour la nuque et/ou la tête de l'utilisateur/utilisatrice, comme montré sur la figure 4 où la structure est représentée en cours d'utilisation dans l'eau E. Les dimensions et les caractéristiques du matériau constitutif de l'élément flottant 2 sont calculées/conçues de manière :

  • d'une part à assurer la flottaison de l'utilisateur/utilisatrice (figure 4), où une partie du tronc et la tête sont hors de l'eau (au-dessus de la surface S de l'eau) ;
  • et d'autre part à constituer un appui ou un support pour la nuque de l'utilisateur/trice (figure 4).
The transverse base 2C of the U is intended to serve as support or support for the neck and / or the head of the user / user, as shown in FIG. figure 4 where the structure is shown in use in water E. The dimensions and characteristics of the constituent material of the floating element 2 are calculated / designed so as:
  • on the one hand to ensure the flotation of the user ( figure 4 ), where part of the trunk and the head are out of the water (above the surface S of the water);
  • and on the other hand to provide support or support for the user's neck ( figure 4 ).

Les parties avant 3 et intermédiaire 4 sont solidaires l'une de l'autre, tandis que l'élément flottant 2 est lié de manière amovible à la partie intermédiaire 4.The front 3 and intermediate 4 parts are integral with each other, while the floating element 2 is removably connected to the intermediate portion 4.

La partie intermédiaire 4 comprend :

  • d'une part deux longerons 5A et 5B, parallèles, et dont l'extrémité libre est reliée à chacune des extrémités libres 2A et 2B de l'élément flottant, et
  • d'autre part une traverse 6 reliant les deux autres extrémités des longerons 5A et 5B entre elles.
The intermediate part 4 comprises:
  • on the one hand two longitudinal members 5A and 5B, parallel, and whose free end is connected to each of the free ends 2A and 2B of the floating element, and
  • on the other hand a cross member 6 connecting the two other ends of the side members 5A and 5B between them.

L'élément flottant 2 et la partie intermédiaire 4 sont sensiblement coplanaires, et de préférence (figure 1) ils forment deux plans à 160° environ au niveau du coude formé par les extrémités libres 2A et 2B.The floating element 2 and the intermediate portion 4 are substantially coplanar, and preferably figure 1 ) they form two planes at about 160 ° at the elbow formed by the free ends 2A and 2B.

La partie avant 3 comporte un bloc 7 parallélépipédique aplati, monté sur la traverse 6 par une partie arrière. Le bloc 7 est de dimensions telles que sa hauteur (transversalement aux plans des parties 2 et 4) est sensiblement inférieure aux deux autres dimensions.The front portion 3 comprises a flattened parallelepiped block 7, mounted on the crosspiece 6 by a rear portion. Block 7 is of such dimensions that its height (transversely to the planes of parts 2 and 4) is substantially smaller than the other two dimensions.

Le bloc 7 est emmanché par sa partie supérieure sur la traverse 6.The block 7 is fitted by its upper part on the crossbar 6.

Sur la partie inférieure du bloc 7 sont fixés les moyens de propulsion hydraulique, à déplacement d'eau, tel qu'une turbine 8 comprenant une coque ou boitier 9 comprenant une entrée d'eau 10 et un conduit de sortie d'eau 11. Dans la coque 9 est montée en rotation, selon un arbre 12 horizontal, transversal à la direction longitudinale de la structure, une roue à aube ou similaire (connue en elle-même et non représentée)On the lower part of the block 7 are fixed the hydraulic propulsion means, water displacement, such as a turbine 8 comprising a shell or housing 9 comprising a water inlet 10 and a water outlet duct 11. In the hull 9 is mounted in rotation, according to a horizontal shaft 12, transverse to the longitudinal direction of the structure, a blade wheel or the like (known in itself and not shown)

En cours d'utilisation (figure 4), la turbine 8 est destinée à être complètement immergée en utilisation, et donc se trouver en dessous du plan définit par la partie intermédiaire 4 et l'élément flottant 2.In use ( figure 4 ), the turbine 8 is intended to be completely immersed in use, and therefore lie below the plane defined by the intermediate portion 4 and the floating element 2.

Sur chaque extrémité distale respective de l'arbre de rotation 12, sont montés des moyens d'entraînement mécanique de la turbine, tel que deux pédales, respectivement 13 et 14, associées chacune à une biellette 15, 16 correspondante reliée à l'arbre 12.On each respective distal end of the rotation shaft 12 are mounted mechanical drive means of the turbine, such as two pedals, respectively 13 and 14, each associated with a corresponding rod 15, 16 connected to the shaft 12 .

En référence à la figure 4, il est montré comment la structure des figures 1 à 3 est utilisée.With reference to the figure 4 , it is shown how the structure of Figures 1 to 3 is used.

L'utilisateur/utilisatrice 17 repose par sa nuque 18 sur la partie arrière 2C de l'élément flottant 2, tandis que ses pieds 19 et 20 portent contre les pédales 13 et 14.The user 17 rests by its neck 18 on the rear portion 2C of the floating element 2, while its feet 19 and 20 bear against the pedals 13 and 14.

La roue rotative de la turbine 8 est ainsi entraînée en rotation par le mouvement des jambes 21 et 22 de l'utilisateur/utilisatrice 17 sur les pédales, à la manière d'une bicyclette. L'utilisateur/trice repose ses mains sur les extrémités 2A et 2B e l'élément flottant.The rotating wheel of the turbine 8 is thus rotated by the movement of the legs 21 and 22 of the user / user 17 on the pedals, in the manner of a bicycle. The user places his hands on the ends 2A and 2B and the floating element.

La turbine disposée à l'intérieur de la coque 9 entraîne l'eau depuis l'orifice d'entrée 10 vers le conduit d'évacuation 11, ce qui crée un mouvement d'eau par déplacement hydraulique, symbolisé par la flèche F. Par réaction, la structure 1 portant l'utilisateur/l'utilisatrice 17 est propulsé vers à l'opposé de la flèche F, c'est-à-dire vers l'avant.The turbine disposed inside the shell 9 draws water from the inlet port 10 to the discharge pipe 11, which creates a movement of water by hydraulic displacement, symbolized by the arrow F. By reaction, the structure 1 carrying the user 17 is propelled towards the opposite of the arrow F, that is to say towards the front.

L'utilisateur/l'utilisatrice 17 n'a pas d'effort à fournir pour se maintenir la tête hors de l'eau grâce à l'élément flottant 2 supportant sa nuque.The user 17 has no effort to provide to keep his head out of the water thanks to the floating element 2 supporting his neck.

Il est fait maintenant référence aux figures 5 à 8 qui montrent un autre aspect de l'invention, sous la forme d'un ensemble destiné à réaliser des exercices physiques des membres inférieurs, de manière immergée, l'ensemble étant posé sur le fond d'une piscine, ou le lit d'une rivière ou le fond de l'océan.Reference is now made to Figures 5 to 8 which show another aspect of the invention, in the form of a set for performing physical exercises of the lower limbs, immersed, the assembly being placed on the bottom of a pool, or the bed of a river or the bottom of the ocean.

Les figures 5 et 6 montrent l'ensemble seul, en vue de côté et de dessus, respectivement, tandis que les figures 7 et 8 montrent l'ensemble des figures 5 et 6, en cours d'utilisation, de côté et en perspective.The Figures 5 and 6 show the whole alone, in side and top view respectively, while the Figures 7 and 8 show all Figures 5 and 6 , in use, sideways and in perspective.

En référence aux figures 5 et 6, ledit ensemble incorpore :

  • la structure décrite ci-dessus en regard des figures 1 à 3 ;
  • un bâti support ; et
  • divers éléments additionnels permettant l'utilisation et le fonctionnement de l'ensemble (figures 7 et 8).
With reference to Figures 5 and 6 , said assembly incorporates:
  • the structure described above with regard to Figures 1 to 3 ;
  • a support frame; and
  • various additional elements allowing the use and operation of the whole ( Figures 7 and 8 ).

Avant l'assemblage de la structure 1 (figures 1 à 4) sur ledit ensemble (figures 5 et 6), la structure 1 est démontée en partie. Plus précisément, l'élément flottant 2 est désolidarisé de la partie intermédiaire 4 (qui reste liée à la partie avant 3).Before assembly of structure 1 ( Figures 1 to 4 ) on said set ( Figures 5 and 6 ), the structure 1 is dismounted in part. More specifically, the floating element 2 is disengaged from the intermediate portion 4 (which remains connected to the front portion 3).

L'ensemble comporte un bâti support 25 sur lequel est destiné à être fixé, de manière fiable et amovible, d'une part l'élément flottant 2, et d'autre part les parties avant 3 et intermédiaire 4 de la structure 1, ainsi que d'autres éléments d'utilisation (selle, guidon, etc.) décrits ci-après.The assembly comprises a support frame 25 on which is intended to be fixed, reliably and removably, on the one hand the floating element 2, and other from the front 3 and intermediate 4 of the structure 1, as well as other use elements (saddle, handlebars, etc.) described below.

Comme montré de côté sur la figure 5, le bâti 25 comporte :

  • un montant arrière 26 vertical, sur lequel sont fixés d'une part l'élément flottant 2 et d'autre part un élément d'assise telle qu'une selle 27 ;
  • un longeron inférieur horizontal 28, relié transversalement à l'extrémité inférieure du montant 26 et s'étendant vers l'avant, ledit longeron 28 étant destiné à être disposé, en utilisation, sensiblement parallèle au sol (figures 5, 7 et 8) ;
  • deux traverses horizontales avant 28A et arrière 28B aux extrémités avant et arrière du longeron inférieur 28 ;
  • un montant avant vertical 29, fixé par son extrémité inférieure à l'extrémité avant du longeron 28 ; sur l'extrémité supérieure 29A est fixé un moyen de préhension sous la forme d'un guidon 30.
As shown from the side on the figure 5 , the frame 25 comprises:
  • a vertical upright 26, on which are fixed firstly the floating element 2 and secondly a seat member such as a seat 27;
  • a horizontal lower spar 28 connected transversely to the lower end of the upright 26 and extending forwards, said spar 28 being intended to be disposed, in use, substantially parallel to the ground ( Figures 5, 7 and 8 );
  • two horizontal crosspieces front 28A and rear 28B at the front and rear ends of the lower spar 28;
  • a vertical front upright 29 fixed by its lower end to the front end of the spar 28; on the upper end 29A is fixed a gripping means in the form of a handlebar 30.

En outre, la partie intermédiaire 4 de la structure 1 est solidarisée par son extrémité arrière (opposée à la partie avant 3) sur l'extrémité supérieure 29A du montant avant 29 du bâti 25. Cette solidarisation est amovible et réalisée à l'aide d'une barre horizontale transversale 31, solidaire du montant avant 29, et sur laquelle sont fixées des pinces de clipsage 32 et 33.In addition, the intermediate portion 4 of the structure 1 is secured by its rear end (opposite to the front portion 3) on the upper end 29A of the front pillar 29 of the frame 25. This fastening is removable and made using a transverse horizontal bar 31, integral with the front post 29, and on which clipping clamps 32 and 33 are fixed.

La partie avant 3 de la structure 1 est fixée, de préférence de manière amovible par clipsage, sur le longeron inférieur 28 du bâti 25, par tout moyen connu.The front portion 3 of the structure 1 is fixed, preferably removably by clipping, on the lower beam 28 of the frame 25 by any known means.

Les figures 5, 7 et 8 montrent que les parties avant 3 et intermédiaire 4 de la structure (et qui sont liées l'une à l'autre) sont inclinées selon des angles respectifs différents par rapport à l'horizontale.The Figures 5, 7 and 8 show that the front 3 and intermediate 4 parts of the structure (and which are connected to each other) are inclined at respective angles different from the horizontal.

En référence aux figures 7 et 8, les moyens de propulsion (la coque 9 de la turbine 8) et les moyens d'entrainement (pédales 13 et 14), sont fixés sur ledit longeron inférieur 28 de manière que l'utilisateur/l'utilisatrice, une fois assis(e) sur la selle 27, puisse poser ses pieds sur les pédales 13 et 14, et disposer ses jambes en position légèrement pliée pour pédaler de manière confortable et efficace sur le plan mécanique.With reference to Figures 7 and 8 , the propulsion means (the hull 9 of the turbine 8) and the drive means (pedals 13 and 14) are fixed on said lower spar 28 so that the user, once seated (e ) on the saddle 27, can put his feet on the pedals 13 and 14, and have his legs slightly bent position to pedal in a comfortable and mechanically efficient way.

L'élément flottant 2 est fixé à l'extrémité arrière de deux montants 34 et 35, parallèles l'un à l'autre, possédant deux coudes chacun, et fixés sur la plaque verticale arrière 26.The floating element 2 is attached to the rear end of two uprights 34 and 35, parallel to each other, having two bends each, and fixed on the rear vertical plate 26.

Le fait de placer l'élément flottant ainsi permet d'une part le rangement de l'élément 2, et d'autre part de former un support du bassin ou du dos pour des exercices des membres supérieursThe fact of placing the floating element thus allows on the one hand the storage of the element 2, and on the other hand to form a support of the pelvis or the back for exercises of the upper limbs

La selle 27 est fixée sur une tige verticale 36 coulissant dans un manchon 37 lui-même solidaire, par une tige 38 horizontale solidaire du montant arrière 26. Ainsi, la selle est réglable en hauteur et en translation horizontale.The seat 27 is fixed on a vertical rod 36 sliding in a sleeve 37 itself secured by a horizontal rod 38 secured to the rear upright 26. Thus, the saddle is adjustable in height and in horizontal translation.

Le guidon 30 est solidaire d'une tige horizontale 39 coulissant dans un manchon 40 horizontal fixé à l'extrémité supérieure du montant avant 29. De plus, le guidon 30 est monté articulé selon un axe horizontal transversal 41, sur l'extrémité arrière de la tige 39. Ainsi, il est possible de régler la position du guidon en translation horizontale, et également en inclinaison dans un plan de rotation vertical.The handlebar 30 is integral with a horizontal rod 39 sliding in a horizontal sleeve 40 fixed to the upper end of the front upright 29. In addition, the handlebar 30 is articulated on a transverse horizontal axis 41, on the rear end of the rod 39. Thus, it is possible to adjust the position of the handlebar in horizontal translation, and also in inclination in a vertical plane of rotation.

La traverse avant 28A est pourvue à ses extrémités libres, de roues ou galets 40A et 40B. La traverse arrière 28B repose sur le sol. L'ensemble est ainsi stable.The front cross member 28A is provided at its free ends with wheels or rollers 40A and 40B. The rear crossmember 28B rests on the ground. The whole is thus stable.

À l'arrière du bâti 25 est fixé un cordon élastique 43 pourvu à son extrémité distale d'une poignée susceptible d'être saisie par l'utilisateur/utilisatrice pour réaliser des exercices de musculation des bras et des épaules, en étant assis sur la selle 27 et tout en pédalant. Enfin, il est prévu à l'extrémité du longeron inférieur 28, un rack 44 de support de disques ou de disques d'haltères 45.At the rear of the frame 25 is fixed an elastic cord 43 provided at its distal end with a handle that can be grasped by the user to perform weight training exercises for the arms and shoulders, while sitting on the saddle 27 and while pedaling. Finally, there is provided at the end of the lower spar 28, a rack 44 for supporting disks or dumbbells 45.
