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, in particular of the lower limbs of a user, in an at least partially submerged manner such as for example in a swimming 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.Numerous types of apparatus are known which are intended to allow a user to perform physical exercises in water, which, in addition to the playful aspect, makes it possible to increase the effort to optimize the exercise aimed to build or re-educate.

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 of the so-called stationary type, comprising a pedal and a saddle, and which is intended to be placed at the bottom of the swimming 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 device, which is a bit like a bicycle without wheels, has a playful side limited by its stationary and fixed nature.

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.A second type of device has been proposed on which the user is supported, which is largely submerged, is provided with a pedal unit 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.One can quote for example in this respect the patent application EP 2,510,986 , but whose structure is relatively complex and bulky 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 patent application FR 2 702 443 shows a floating frame provided, at one end with a bearing surface for the user's pelvis, and at another end of a propeller connected to a crankset fixed to the frame. A priori, the user being supported only by his pelvis, must make a significant effort to keep the head above water, which requires some practice. Also note that a good part of the legs is not submerged, 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 you to enjoy the marine element or the pool without worrying about keeping your head above water. By definition, these playful floating structures are not, in themselves, intended to carry out physical strength training exercises. The patent US 6,276,979 show an example.

Les brevets US 1 071 113 , US 5 368 507 et FR3017364 montrent également d'autres exemples de structures flottantes.Licences US 1,071,113 , US 5,368,507 and FR3017364 also show other examples of floating structures.

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 making it possible to carry out physical exercises in an almost completely submerged manner, in complete safety, while having the playful nature linked to movement in the water.

L'invention vise à proposer une telle structure ou appareil présentant les avantages mentionnés ci-dessus.The invention aims to propose 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) est telle que définie à la revendication 1.To this end, according to the invention, the structure intended to perform physical exercises in a liquid medium (swimming pool, rivers, oceans) is as defined in claim 1.

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 tubular element in the shape of a general U comprising two spaced apart 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 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 branch of the U opposite the base of said U is removably connected to a first end of a beam, the second end of which 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 spars) 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 advantageously are of the pedal type, and the propulsion means advantageously consist of a turbine associated with a hull or case.

L'utilisation de la structure ci-dessus est : 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 l'utilisateur/trice.The use of the above structure is: in the extended position of the user, and in displacement of the structure in the water, the propulsion means and the associated drive means being linked to the element floating which supports the user.

Une autre utlisation de la structure ci-dessus, ne faisant pas partie de l'invention, est 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.Another use of the above structure, which is not part of the invention, is in a seated position, fixedly on the ground (pool or ocean floor), the propulsion means and the training means associated being separated from the floating element.

Ainsi, la structure peut être utilisée dans un ensemble, ne faisant pas partie de l'invention, 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 structure can be used in a set, not part of the invention, to perform physical exercises of the lower limbs, intended to be fully immersed and placed on the bottom of a pool, or the bed of a river or ocean floor, depending on usage option B) above.

Un tel ensemble, ne faisant pas partie 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.Such an assembly, not forming part of the invention, comprises a frame which, on the one hand is provided with a seat (saddle) and with a gripping member such as a handlebar, and on the other hand on which is capable of being fixed, in a removable manner, the structure as mentioned previously, and other elements allowing the use and the 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 arranged at the rear of the frame;
  • the propulsion means and the drive means (pedal) are fixed to the base and in the front part 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 in inclination, and in that the frame is provided at its front end with rolling means and at its rear end. skates.

Ainsi, l'invention est une structure semi flottante pour l'exercice physique, permettant de se déplacer dans l'eau, à la surface de celle-ci.Thus, the invention is a semi-floating structure for physical exercise, making it possible to move in the water, on the surface thereof.

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 following description, the terms "upper", "lower", "front", "rear", "frontal", "proximal", "distal", "top", "bottom" are used in the context of '' a normal installation of the structure and the assembly, in relation to the position of use by a user.

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 made of a material such as a foam, of the type for example "frit" of swimming pool, with 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 a support or support for the neck and / or the head of the user, as shown on the figure 4 where the structure is shown in use in water E. The dimensions and characteristics of the material of the floating element 2 are calculated / designed so:
  • on the one hand to ensure the flotation of the user ( figure 4 ), where part of the trunk and the head are above the water (above the surface S of the water);
  • and on the other hand to constitute a support or a support for the neck of the user 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 one another, while the floating element 2 is removably linked to the intermediate part 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 includes:
  • on the one hand, two longitudinal members 5A and 5B, parallel, the free end of which is connected to each of the free ends 2A and 2B of the floating element, and
  • on the other hand a cross 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 part 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 part 3 comprises a flattened parallelepiped block 7, mounted on the cross-member 6 by a rear part. The block 7 is of dimensions such that its height (transverse to the planes of the parts 2 and 4) is substantially less 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 cross-member 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, with displacement of water, such as a turbine 8 comprising a shell or box 9 comprising a water inlet 10 and a water outlet conduit 11. In the shell 9 is rotatably mounted, according to a horizontal shaft 12, transverse to the longitudinal direction of the structure, a paddle 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 submerged in use, and therefore to be below the plane defined by the intermediate part 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 link 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 his neck 18 on the rear part 2C of the floating element 2, while his 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 de l'élément flottant.The rotary wheel of the turbine 8 is thus driven in rotation by the movement of the legs 21 and 22 of the user 17 on the pedals, in the manner of a bicycle. The user rests his hands on the ends 2A and 2B of 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 placed inside the shell 9 drives the water from the inlet 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 opposite 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 make to keep his head above water thanks to the floating element 2 supporting his neck.

Il est fait maintenant référence aux figures 5 à 8 qui montrent un ensemble, ne faisant pas partie de l'invention, 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 an assembly, not forming part of the invention, intended for performing physical exercises of the lower limbs, in a submerged manner, the assembly being placed on the bottom of a swimming pool, or the bed of a river or the ocean floor.

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 unit alone, viewed from the side and from above, respectively, while the Figures 7 and 8 show all of Figures 5 and 6 , in use, from the side 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 set 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 set ( 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 assembling the structure 1 ( figures 1 to 4 ) on said set ( Figures 5 and 6 ), the structure 1 is partially dismantled. More specifically, the floating element 2 is separated from the intermediate part 4 (which remains linked to the front part 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, in a reliable and removable manner, on the one hand the floating element 2, and on the other hand the front 3 and intermediate 4 parts of the structure 1, thus than other elements of use (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 rear upright 26 vertical, on which are fixed on the one hand the floating element 2 and on the other hand a seat element such as a saddle 27;
  • a horizontal lower beam 28, connected transversely to the lower end of the upright 26 and extending forward, said beam 28 being intended to be disposed, in use, substantially parallel to the ground ( Figures 5, 7 and 8 );
  • two front horizontal cross members 28A and rear 28B at the front and rear ends of the lower beam 28;
  • a vertical front upright 29, fixed by its lower end to the front end of the beam 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 part 4 of the structure 1 is secured by its rear end (opposite to the front part 3) on the upper end 29A of the front upright 29 of the frame 25. This attachment is removable and produced using a transverse horizontal bar 31, integral with the front upright 29, and on which are clips clips 32 and 33.

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 part 3 of the structure 1 is fixed, preferably removably by clipping, to the lower spar 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 linked to each other) are inclined at respective respective angles relative to 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 shell 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 in a slightly bent position to pedal comfortably and mechanically effectively.

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 fixed to the rear end of two uprights 34 and 35, parallel to each other, having two elbows each, and fixed to 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 supérieursPlacing the floating element in this way allows element 2 to be stored on the one hand, and on the other hand to form a support for the pelvis or back for upper limb exercises

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 saddle 27 is fixed to a vertical rod 36 sliding in a sleeve 37 which is itself integral, by a horizontal rod 38 integral with the upright rear 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 mounted articulated along a transverse horizontal axis 41, on the rear end of the rod 39. Thus, it is possible to adjust the position of the handlebars 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 cross member 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 capable of being grasped by the user to perform strength training exercises for the arms and shoulders, while sitting on the saddle 27 and while pedaling. Finally, a rack 44 for supporting discs or dumbbell discs 45 is provided at the end of the lower spar 28.
