Selon les documents US 2004/0259691 et WO 2004/112910, l'appareil est constitué d'un élément présentant une forme arrondie, fuselée ou en ogive munie d'une embase permettant le maintien dudit appareil ; la forme fuselée comprend des perforations pour réduire la résistance de l'appareil et stabiliser celui-ci lors de ses déplacements dans l'eau, et des éléments plats ou ailettes rigides augmentant la résistance de l'appareil lors de la poussée avec le bras. Selon le document US 4 509 744, l'appareil se présente sous la forme d'une raquette ou pale munie d'une embase pour le maintien de ladite raquette, celle-ci étant légèrement déformable pour réduire la résistance de la raquette lors du retour en position de l'appareil après avoir réalisé un effort.The documents US 4,685,667 and US 6,899,581 disclose an apparatus for aquatic gymnastics in the form of a disc having in its center a base for holding it with the hand. According to the documents US Pat. No. 5,651,710 and US Pat. No. 7,147,526, the apparatus for aquatic gymnastics is in the form of a blade comprising a base allowing the said blade to be held with the hand, or even the threading of the hand. in the manner of a glove, said blade optionally comprising curved shapes and orifices favoring in particular the flow of the fluid to limit the resistance of the apparatus during the practice of the exercise during the pushing or pulling with the arms. According to the documents US 2004/0259691 and WO 2004/112910, the apparatus consists of an element having a rounded, tapered or ogival shape provided with a base for maintaining said apparatus; the tapered shape comprises perforations to reduce the resistance of the device and stabilize it during its movements in the water, and flat elements or rigid fins increasing the strength of the device during the pushing with the arm. According to the document US Pat. No. 4,509,744, the apparatus is in the form of a racket or blade provided with a base for maintaining said racket, the latter being slightly deformable to reduce the resistance of the racket when returning. in position of the device after making a effort.
De teis appareils pour la gymnastique aquatique ont pour inconvénient de maintenir un effort important lors du retour en position de l'appareil dans l'eau pour effectuer un nouveau cycle de travail, du fait de la rigidité dudit appareil, les pales, raquettes, éléments plats ou ailettes, qui sont rigides ou éventuellement légèrement déformables, maintenant une résistance importante dans l'eau durant le retour en position initiale. Le sportif ne dispose donc quasiment pas de temps de récupération, celui-ci devant enchaîner directement le cycle de travail suivant. En outre, ces appareils n'offrent pas ou peu de stabilité durant les mouvements de retour en position initiale.Such devices for water gymnastics have the disadvantage of maintaining a significant effort when returning to the position of the device in the water to perform a new work cycle, because of the rigidity of said apparatus, blades, rackets, elements flat or fins, which are rigid or possibly slightly deformable, maintaining significant resistance in the water during the return to the initial position. The athlete therefore has almost no recovery time, it must directly follow the next work cycle. In addition, these devices offer little or no stability during the movements back to the initial position.
Concernant les documents EP 1 498 159 et US 6 540 647, ceux-ci divulguent un appareil pour la gymnastique aquatique comprenant une embase ou base permettant le maintien avec la main ou le pied dudit appareil, vis-à-vis de laquelle sont articulées une ou plusieurs pales, au moyen de charnières mécaniques, la ou lesdites pales offrant une résistance dans l'eau lors d'un mouvement du bras ou de la jambe, puis se rabattant lors du retour en position du membre pour effectuer un nouveau cycle d'exercice. Une telle conception d'appareil équipé de charnières mécaniques peut occasionner des pincements sur le corps de l'utilisateur lorsque celui-ci effectue un mouvement avec l'appareil et positionne la charnière mécanique ou les arêtes adjacentes de deux pales au contact d'une partie du corps au moment de procéder à une poussée ou une traction sur l'appareil opposant une résistance, c'est-à-dire lorsque les pales se déploient. En outre, les pales peuvent se déployer indépendamment l'une de l'autre et entraîner des problèmes de stabilité ou une mauvaise répartition de l'effort durant le déplacement de l'appareil dans l'eau.With regard to the documents EP 1 498 159 and US Pat. No. 6,540,647, these disclose an apparatus for aquatic gymnastics comprising a base or base allowing holding with the hand or the foot of said apparatus, with respect to which are articulated a or more blades, by means of mechanical hinges, said blade or blades offering resistance in the water during a movement of the arm or leg, and then bending when returning to the limb position to perform a new exercise cycle. Such an apparatus design equipped with mechanical hinges may cause pinching on the body of the user when the latter makes a movement with the apparatus and positions the mechanical hinge or the adjacent edges of two blades in contact with a part of the body when pushing or pulling on the device opposing resistance, ie when the blades are deployed. In addition, the blades can deploy independently of each other and cause stability problems or poor distribution of effort during movement of the device in the water.
Les documents FR 739 070, FR 1 049 110, FR 1 502 877 et FR 2 537 876 divulguent des appareils pour la gymnastique aquatique comprenant une base agencée pour être maintenue avec la main ou le pied, voire pour être disposés autour de la cheville ou de la jambe. En outre, ces appareils disposent d'une jupe, ou d'une voilure souple, présentant la forme d'une corolle, solidaire de la base et apte à se déformer sous la pression de l'eau exercée durant le déplacement de l'appareil, c'est-à-dire lors d'une poussée ou d'une traction exercée sur ceiui-ci. Dans ie cas d'une voiiure soupie, celle-ci comprend des armatures ou des lamelles métalliques s'étendant radialement depuis la base jusque l'extrémité externe de la jupe, ces armatures ou lamelles permettant de rigidifier la jupe lorsqu'elle est déployée, et qu'elle oppose une résistance dans l'eau, c'est-à-dire lorsque la corolle s'ouvre. Selon cette conception, les armatures ou lamelles peuvent éventuellement se déformer et la voilure se retourner lors d'une pression trop importante exercée sur celle-ci. Dans le cas des jupes plus rigides et munies de nervures, telles que celles décrites dans FR 2 537 876, celles-ci se replient au niveau desdites nervures lors du retour en position initiale du bras ou de la jambe après avoir réalisé une poussée ou une traction sur l'appareil opposant une résistance. Selon cette conception, l'utilisateur peut se pincer lorsqu'il s'apprête à effectuer un nouveau cycle de travail, au moment où la jupe se redéploie et lorsqu'elle est positionnée au contact d'une partie du corps, entraînant un risque de pincement de la peau qui se prend dans ladite nervure sur la jupe. Par ailleurs, la conception de la jupe lorsque celle-ci se replie au niveau des nervures, présente pour inconvénient de ne pas se replier uniformément autour du membre lors du retour en position initiale de l'appareil qui maintient une résistance importante et peut éventuellement louvoyer dans l'eau durant le retour en position de l'appareil.The documents FR 739 070, FR 1 049 110, FR 1 502 877 and FR 2 537 876 disclose apparatus for water gymnastics comprising a base arranged to be held with the hand or the foot, or even to be arranged around the ankle or of the leg. In addition, these devices have a skirt, or a flexible blade, having the shape of a corolla, integral with the base and able to deform under the pressure of the water exerted during movement of the device , that is to say during a push or a pull on this one. In the case of a soupie wall, it comprises reinforcements or metal lamellae extending radially from the base to the outer end of the skirt, these armatures or lamellae for stiffening the skirt when it is deployed, and that it opposes a resistance in the water, that is to say when the corolla opens. According to this design, the reinforcements or lamellae may possibly deform and the blade turn over when too much pressure is exerted on it. In the case of the stiffer skirts and provided with ribs, such as those described in FR 2 537 876, these fold at the level of said ribs when returning to the initial position of the arm or the leg after having made a push or a traction on the device opposing a resistance. According to this design, the user can pinch himself when he is about to perform a new work cycle, when the skirt redeploys and when it is positioned in contact with a part of the body, causing a risk of pinching of the skin which is caught in said rib on the skirt. Furthermore, the design of the skirt when the latter folds at the ribs, has the disadvantage of not folding evenly around the member when returning to the initial position of the apparatus which maintains a high resistance and can optionally tack in the water during the return to the position of the device.
On connaît également les documents FR 1 011 324 et US 1 545 807 qui divulguent un appareil pour la gymnastique aquatique, lequel comprend une base agencée pour être maintenue avec un pied ou une main, et une voilure, notamment en forme de corolle.Also known are documents FR 1 011 324 and US 1 545 807 which disclose an apparatus for aquatic gymnastics, which comprises a base arranged to be held with a foot or a hand, and a wing, in particular in the form of a corolla.
La voilure comprend une jupe souple et des ailettes rigides rapportées sur la jupe. En outre, des moyens de butée sont agencés sur la base pour former butée contre les ailettes rigides lors du déplacement de la jupe.The wing includes a flexible skirt and rigid fins reported on the skirt. In addition, abutment means are arranged on the base to form a stop against the rigid fins during movement of the skirt.
Selon FR 1 011 324, le bord périphérique interne de la jupe est assujetti à l'intérieur d'un bourrelet périphérique sur la base, en forme d'escargot, le déploiement de la jupe permettant l'enroulement de son bord périphérique interne autour du bourrelet jusqu'à ce qu'une portion circulaire arrière des ailettes vienne au contact dudit bourrelet et que la tension sur le bord périphérique interne enroulé autour du bourrelet stoppe l'enroulement et ainsi le déploiement de la jupe.According to FR 1 011 324, the inner peripheral edge of the skirt is secured inside a peripheral bead on the snail-shaped base, the deployment of the skirt allowing the winding of its inner peripheral edge around the bead until a circular rear portion of the fins comes into contact with said bead and that the tension on the inner peripheral edge wound around the bead stops the winding and thus the deployment of the skirt.
Selon US 1 545 807, une première réalisation consiste à fixer le bord interne de la jupe souple à l'intérieur de la base en sorte de positionner les ailettes, rapportées sur ladite jupe, à proximité des moyens de butée constitués par un rebord externe sur la base, le bord angulaire arrière des ailettes venant en butée sur ledit rebord lors du déploiement de la jupe. Selon une seconde réalisation divulguée dans ce document, les ailettes rapportées sur la jupe souple sont constituées d'une âme rigide intégrée dans un revêtement souple, le bord interne dudit revêtement souple et le bord périphérique interne de la jupe étant concomitamment fixés à l'intérieur de la base métallique, en sorte que le bord angulaire arrière de l'âme vienne en butée sur un rebord métallique externe agencé sur la base. L'appareil pour la gymnastique aquatique selon l'invention permet de pallier tout ou partie des inconvénients existants et constitue en outre une alternative de conception vis-à-vis des appareils pour la gymnastique aquatique divulgués dans les documents FR 1 011 324 et US 1 545 807, cette alternative de conception présentant notamment pour avantage de faciliter la conception et l'assemblage des éléments de l'appareil pour la gymnastique aquatique, ainsi que d'améliorer la forme hydrodynamique de la voilure, en vue de limiter les turbulences.According to US 1,545,807, a first embodiment consists in fixing the inner edge of the flexible skirt inside the base so as to position the fins, attached to said skirt, close to the abutment means constituted by an external rim on the base, the rear angular edge of the fins abutting on said rim during deployment of the skirt. According to a second embodiment disclosed in this document, the fins attached to the flexible skirt consist of a rigid core embedded in a flexible coating, the inner edge of said flexible covering and the inner peripheral edge of the skirt being concomitantly fixed inside. of the metal base, so that the rear angular edge of the core abuts on an outer metal rim arranged on the base. The apparatus for aquatic gymnastics according to the invention makes it possible to overcome all or part of the existing drawbacks and also constitutes a design alternative with respect to the apparatus for aquatic gymnastics disclosed in the documents FR 1 011 324 and US 1 545 807, this alternative design having the particular advantage of facilitating the design and assembly of the elements of the apparatus for aquatic gymnastics, as well as improve the hydrodynamic shape of the wing, to limit turbulence.
A ce titre, l'appareil pour la gymnastique aquatique, selon l'invention, comprend une base agencée pour être maintenue notamment avec un pied ou une main, et une voilure présentant notamment la forme d'une corolle, cette voilure étant solidaire de la base et articulée avec celle-ci, et apte à se déformer sous la pression de l'eau exercée durant les déplacements de l'appareil, ladite voilure se déployant lors d'une poussée sur l'appareil et se fermant lors d'une traction sur celui-ci, voire inversement.As such, the apparatus for aquatic gymnastics, according to the invention, comprises a base arranged to be maintained in particular with a foot or a hand, and a wing having in particular the shape of a corolla, this wing being integral with the base and articulated with it, and able to deform under the pressure of the water exerted during the movements of the apparatus, said blade being deployed during a thrust on the apparatus and closing during traction on this one, or vice versa.
La voilure est constituée d'une jupe souple et d'ailettes rigides, la jupe étant surmoulée sur les ailettes ; cela présente pour avantage de supprimer tout assujettissement supplémentaire entre la jupe et les ailettes, et de supprimer la présence des ailettes au-dessus de la jupe, ce qui favorise l'écoulement uniforme de l'eau, sans perturbation lors de la fermeture de la jupe. La jupe, en forme de corolle, présente un bord périphérique interne et un bord périphérique externe, le bord périphérique interne de la jupe étant solidaire d'un bord périphérique externe agencé sur la base. Les ailettes sont réparties radialement autour de la jupe, les bords internes des ailettes étant distants du bord périphérique interne de la jupe. Ainsi, seule la jupe souple est solidarisée avec la base, au niveau de son bord périphérique externe, la souplesse de la jupe permettant de déformer celle-ci et de constituer l'articulation de la voilure avec la base.The wing consists of a flexible skirt and rigid fins, the skirt being overmolded on the fins; this has the advantage of eliminating any additional securing between the skirt and the fins, and to eliminate the presence of the fins above the skirt, which promotes the uniform flow of water, without disturbance when closing the skirt. The skirt, in the form of a corolla, has an inner peripheral edge and an outer peripheral edge, the inner peripheral edge of the skirt being integral with an outer peripheral edge arranged on the base. The fins are distributed radially around the skirt, the inner edges of the fins being spaced from the inner peripheral edge of the skirt. Thus, only the flexible skirt is secured to the base, at its outer peripheral edge, the flexibility of the skirt to deform it and to form the articulation of the wing with the base.
En outre, la base comprend des moyens de butée répartis sur son bord périphérique externe, ces moyens de butée étant agencés pour prendre appui sur la face supérieure des ailettes lorsque la jupe est solidarisée à la base. Une telle conception présente pour avantage de disposer d'une souplesse convenable lors du repli de la voilure durant le retour en position de l'appareil, et au contraire, d'une bonne rigidité de la voilure déployée ; on évite ainsi que la voilure se retourne lorsqu'elle se déploie et oppose une résistance durant la poussée ou la traction, les risques de retournement étant éliminés par les moyens de butée sur la base qui prennent appui sur les ailettes rigides. Par ailleurs, un appui des moyens de butée sur la face supérieure des ailettes plutôt que sur leur bord arrière, tel que prévu dans FR 1 011 324 et US 1 545 807, présente pour avantage d'éviter toute tension dans la zone d'assujettissement entre la base et la jupe.In addition, the base comprises stop means distributed on its outer peripheral edge, these abutment means being arranged to bear on the upper face of the fins when the skirt is secured to the base. A such a design has the advantage of having a suitable flexibility during the folding of the wing during the return to position of the aircraft, and on the contrary, a good rigidity of the deployed wing; this avoids the wing turns when it deploys and opposes resistance during pushing or pulling, the risk of overturning being eliminated by the abutment means on the base which bear on the rigid fins. Furthermore, a support stop means on the upper face of the fins rather than their rear edge, as provided in FR 1 011 324 and US 1 545 807, has the advantage of avoiding any tension in the area of subjection between the base and the skirt.
De manière préférentielle, la jupe souple comprend des évidements s'étendant autour de celle-ci, depuis son bord périphérique interne, ces évidements étant disposés entre les ailettes. Une telle conception améliore la souplesse de la voilure et compense la rigidité des ailettes pour assurer une fermeture convenable de ladite voilure et limiter au maximum la résistance de l'appareil lors de son retour en position pour réaliser un nouveau cycle de travail. Ces évidements servent également à réduire la résistance de l'appareil dans l'eau lorsque la voilure est déployée, pour limiter l'effort que doit fournir l'utilisateur durant le travail, et à stabiliser ladite voilure en favorisant l'écoulement de l'eau au travers desdits évidements.Preferably, the flexible skirt comprises recesses extending around it, from its inner peripheral edge, these recesses being disposed between the fins. Such a design improves the flexibility of the wing and compensates for the rigidity of the fins to ensure proper closure of said wing and minimize the resistance of the aircraft when returning to position to achieve a new work cycle. These recesses are also used to reduce the resistance of the device in the water when the wing is deployed, to limit the effort that must provide the user during work, and to stabilize said wing by promoting the flow of the water through said recesses.
De manière préférentielle et non limitative, la base se compose de deux pièces. La première pièce dite inférieure, est disposée autour de la jupe, tandis que la seconde pièce, dite supérieure, est disposée au-dessus de la jupe. Ces deux pièces sont aptes à être assemblées l'une avec l'autre, le bord périphérique interne de la jupe étant maintenu coincé entre ces deux pièces inférieure et supérieure lorsque celles-ci sont assemblées. Cette conception facilite avantageusement l'assemblage de la jupe sur la base en assurant un très bon assujettissement entre les éléments.Preferably and not limitation, the base consists of two pieces. The first so-called lower part, is arranged around the skirt, while the second piece, said upper, is arranged above the skirt. These two parts are able to be assembled with each other, the inner peripheral edge of the skirt being kept wedged between these two lower and upper parts when they are assembled. This design advantageously facilitates the assembly of the skirt on the base ensuring a very good subjection between the elements.
En outre, la base comprend une poignée centrale apte à être maintenue avec la main ou à recevoir une pièce rapportée pour son maintien avec le pied. A ce sujet, l'invention concerne également un kit pour la gymnastique aquatique composé d'au moins un appareil pour la gymnastique aquatique, selon l'invention, et disposant d'une poignée centrale, et d'au moins un support, notamment une chaussure, apte à recevoir le pied de l'utilisateur ou une autre partie du corps, celui-ci comprenant une semelle et des moyens de fixation agencés sur la face inférieure de ladite semelle pour être fixés sur ladite poignée centrale de la base.In addition, the base comprises a central handle adapted to be held with the hand or to receive a patch for its support with the foot. In this regard, the invention also relates to a kit for aquatic gymnastics consisting of at least one device for aquatic gymnastics, according to the invention, and having a central handle, and at least one support, including a shoe, adapted to receive the foot of the user or another part of the body, the latter comprising a sole and fastening means arranged on the underside of said sole to be fixed on said central handle of the base.
D'autres caractéristiques de la présente invention apparaîtront à la lecture de la description suivante s'appuyant sur des figures, parmi lesquelles : - la figure 1 représente un mode préférentiel de conception de l'appareil pour la gymnastique aquatique selon l'invention, en vue de dessus ; la figure 2 représente l'appareil selon la figure 1 en vue de dessous ; - la figure 3 présente la jupe composant la voilure de l'appareil selon les figures 1 et 2 ; la figure 4 représente un élément constituant la partie supérieure de la base ; la figure 5 représente un élément constituant la partie inférieure de la base ; la figure 6 représente un mode préférentiel de conception du kit pour la gymnastique aquatique selon l'invention ; les figures 7 et 8 représentent le mode d'assemblage de la chaussure sur l'appareil pour la gymnastique aquatique selon l'invention.Other features of the present invention will appear on reading the following description based on figures, among which: FIG. 1 represents a preferential mode of design of the apparatus for aquatic gymnastics according to the invention, in top view ; Figure 2 shows the apparatus according to Figure 1 in a view from below; - Figure 3 shows the skirt constituting the wing of the apparatus according to Figures 1 and 2; Figure 4 shows an element constituting the upper part of the base; FIG. 5 represents an element constituting the lower part of the base; FIG. 6 represents a preferential mode of design of the kit for aquatic gymnastics according to the invention; Figures 7 and 8 show the method of assembly of the shoe on the apparatus for aquatic gymnastics according to the invention.
Tel qu'illustré sur les figures 1 et 2, l'appareil pour la gymnastique aquatique comprend une base 3 et une voilure 5 qui présente la forme d'une corolle. Cette voilure 5 présente une face supérieure 5a, illustrée en figure 1, et une face inférieure 5b, illustrée en figure 2. Lorsque l'eau exerce une pression sur la face inférieure 5b, lors d'une poussée ou d'une traction sur l'appareil, selon le sens que l'on tient celui-ci avec le pied ou la main, voire toute autre partie du corps, la voilure est alors en position déployée et oppose une résistance qui nécessite à l'utilisateur d'exercer un effort supplémentaire pour déplacer ledit appareil dans l'eau, durant lequel il travaille. Au contraire, lorsque l'eau exerce une pression sur la face supérieure 5a de la voilure, lors d'une traction ou d'une poussée sur celui-ci, ladite voilure se ferme pour permettre l'écoulement de l'eau durant le déplacement de l'appareil sans opposer de résistance, afin de permettre à l'utilisateur de ne pas exercer d'effort supplémentaire durant le retour en position de l'appareil pour réaliser un nouveau cycle de travail, ce qui lui laisse un temps de récupération avant de procéder à un nouvel effort musculaire.As illustrated in Figures 1 and 2, the apparatus for water gymnastics comprises a base 3 and a wing 5 which has the shape of a corolla. This wing 5 has an upper face 5a, illustrated in FIG. 1, and a lower face 5b, illustrated in FIG. 2. When the water exerts a pressure on the lower face 5b, during a push or a pull on the device, according to the meaning that we hold this one with the foot or hand, or any other part of the body, the blade is then in the deployed position and opposes a resistance that requires the user to exert additional effort to move said device in the water, during which he works. On the contrary, when the water exerts a pressure on the upper face 5a of the wing, during a traction or a push on it, said wing closes to allow the flow of water during the displacement of the device without opposing resistance, to allow the user not to exert extra effort during the return to position of the device to achieve a new work cycle, which leaves him a recovery time before to make a new muscular effort.
Tel qu'illustré sur les figures 1 à 3, la voilure est constituée d'une jupe 7 et d'ailettes 9. Cette jupe 7 est réalisée dans un matériau élastomère, de préférence du type SEBS, offrant une souplesse à ladite jupe. Au contraire, les ailettes sont réalisées dans un matériau polymère, notamment du polypropylène, offrant une rigidité aux dites ailettes. La jupe 7 qui constitue la forme en corolle de la voilure, présente un bord périphérique interne 11 et un bord périphérique externe 13. Le bord périphérique interne 11 est solidaire de la base 3 qui présente un bord périphérique externe 15 au niveau duquel est maintenu ledit bord périphérique interne 11, tel qu'illustré en figure 2. En outre, les ailettes sont réparties radialement autour de la jupe. De manière préférentielle et non limitative, ces ailettes 9 sont disposées uniformément autour de la jupe 7 ; celles-ci sont de préférence au nombre de 5, tel qu'illustré en figure 3, ou au nombre de 7, tel qu'illustré en figures 1 et 2. Par ailleurs, les bords internes 17 des ailettes 9 sont distants du bord périphérique interne 11 de la jupe. On assure ainsi que l'assemblage de la base avec la voilure est réalisé au niveau de la jupe qui présente une souplesse permettant de déformer la corolle de manière à la déployer ou à la fermer, sans que la rigidité desdites ailettes n'interfère sur la souplesse de la voilure durant son déploiement ou sa fermeture, le bord périphérique interne 11 de la jupe 7 jouant le rôle d'articulation. En outre, les bords externes 23 de ces ailettes 9 sont disposés à distance du bord périphérique externe 13 de la jupe, ce qui permet de conserver une souplesse de la voilure 5 au niveau de son bord périphérique externe. On évite ainsi tout risque de choc ou de coup sur les parties du corps lorsque l'appareil 1 vient au contact de celles-ci de manière inopinée durant la pratique de la gymnastique. De manière préférentielle et non limitative, la jupe 7 comprend des évidements 25 qui s'étendent radialement autour de celle-ci, depuis son bord périphérique interne, c'est-à-dire jusqu'au niveau de la liaison avec le bord périphérique externe 15 de la base 3. Ces évidements 25 présentent de préférence la forme d'un pétale, lesdits pétales s'étendant depuis le bord périphérique interne 11 jusqu'à une distance plus ou moins proche du bord périphérique externe 13 de ladite jupe, tel qu'illustré sur les figures 1 à 3, l'extrémité externe 26 des pétales correspondant plus ou moins avec la position des bords externes 23 des ailettes 9. En outre, ces évidements 25 sont disposés entre les ailettes 9. De tels évidements ont pour avantage d'améliorer la souplesse de la voilure durant sa fermeture. En outre, ces évidements 25 distants du bord externe 13 de la jupe 7 permettent de conserver un lien ou une liaison suffisamment rigide entre les ailettes 9 de manière à assurer leur déploiement simultané lors d'une pression de l'eau sur la face inférieure 5b de la voilure 5 tout en évitant les risques de pincement de la peau, et inversement leur fermeture simultanée lors d'une pression de l'eau sur la face supérieure 5a de ladite voilure 5. Il serait toutefois possible de concevoir des évidements 25 s'étendant depuis le bord périphérique interne 11 jusqu'au bord périphérique externe 13 de la jupe, en prévoyant un lien ou une liaison intermédiaire, par exemple à mi-distance entre le bord périphérique interne et le bord périphérique externe, de manière à conserver une rigidité entre lesdites ailettes 9.As shown in Figures 1 to 3, the wing is constituted by a skirt 7 and fins 9. This skirt 7 is made of an elastomeric material, preferably of the SEBS type, providing flexibility to said skirt. On the contrary, the fins are made of a polymeric material, especially polypropylene, offering rigidity to said fins. The skirt 7 which constitutes the corolla shape of the wing, has an inner peripheral edge 11 and an outer peripheral edge 13. The inner peripheral edge 11 is integral with the base 3 which has an outer peripheral edge 15 at which is maintained said internal peripheral edge 11, as shown in Figure 2. In addition, the fins are distributed radially around the skirt. In a preferential and nonlimiting manner, these fins 9 are arranged uniformly around the skirt 7; these are preferably 5 in number, as illustrated in FIG. 3, or in the number of 7, as illustrated in FIGS. 1 and 2. Furthermore, the internal edges 17 of the fins 9 are distant from the peripheral edge internal 11 of the skirt. This ensures that the assembly of the base with the wing is made at the level of the skirt which has a flexibility to deform the corolla so as to deploy or close, without the rigidity of said fins interferes with the flexibility of the wing during deployment or closure, the inner peripheral edge 11 of the skirt 7 acting as articulation. In addition, the outer edges 23 of these fins 9 are arranged at a distance from the outer peripheral edge 13 of the skirt, which allows to maintain a flexibility of the wing 5 at its outer peripheral edge. This avoids any risk of shock or stroke on the body parts when the device 1 comes into contact with them unexpectedly during the practice of gymnastics. In a preferred and nonlimiting manner, the skirt 7 comprises recesses 25 which extend radially around it, from its inner peripheral edge, that is to say up to the level of the connection with the external peripheral edge. These recesses 25 preferably have the shape of a petal, said petals extending from the inner peripheral edge 11 to a distance more or less close to the outer peripheral edge 13 of said skirt, such as 1 to 3, the outer end 26 of the petals corresponding more or less with the position of the outer edges 23 of the fins 9. In addition, these recesses 25 are arranged between the fins 9. Such recesses have the advantage to improve the flexibility of the wing during its closure. In addition, these recesses 25 remote from the outer edge 13 of the skirt 7 allow to maintain a link or a sufficiently rigid connection between the fins 9 so as to ensure their simultaneous deployment during a pressure of the water on the underside 5b of the wing 5 while avoiding the risk of pinching of the skin, and conversely their simultaneous closure during a pressure of the water on the upper face 5a of said wing 5. It would however be possible to design recesses 25 ' extending from the inner peripheral edge 11 to the outer peripheral edge 13 of the skirt, providing a link or an intermediate connection, for example midway between the inner peripheral edge and the outer peripheral edge, so as to maintain rigidity between said fins 9.
De manière préférentielle et non limitative, la jupe souple 7 en matériau élastomère est surmoulée sur les ailettes rigides en matériau polymère durant le processus de fabrication de la voilure. Cette conception présente pour avantage d'être facile à mettre en œuvre industriellement et d'assurer une excellente tenue entre les ailettes 9 et la jupe 7. Une portion de ces ailettes 9 peut toutefois être apparente à la surface de la jupe 7 pour améliorer l'esthétisme du produit et réaliser des graphismes ou des jeux de coloris sur la surface de la voilure 5. Selon une variante de conception, il est toutefois possible de prévoir un assemblage mécanique entre les ailettes 9 rigides et la jupe 7 souple, lesdites ailettes 9 étant dans ce cas fixées mécaniquement sur la face supérieure de ladite jupe 7 par collage, clipsage, ou tout autre moyen de fixation.In a preferential and nonlimiting manner, the flexible skirt 7 made of elastomer material is overmolded on the rigid fins made of polymer material during the manufacturing process of the wing. This design has the advantage of being easy to implement industrially and to ensure excellent hold between the fins 9 and the skirt 7. A portion of these fins 9 may however be apparent on the surface of the skirt 7 to improve the aesthetics of the product and make graphics or color schemes on the surface of the wing 5. According to a variant of the design, it is however possible to provide a mechanical assembly between the rigid fins 9 and the flexible skirt 7, said fins 9 being in this case mechanically fixed on the upper face of said skirt 7 by gluing, clipping, or any other fastening means.
Les figures 1, 2, 4 et 5 présentent la base 3 de l'appareil pour la gymnastique aquatique 1 selon l'invention. De manière préférentielle et non limitative, cette base 3 est constituée de deux pièces 27, 29. La première pièce 27, illustrée en figures 2 et 5, constitue la partie inférieure de la base 3. Tel qu'illustré sur la figure 2, cette pièce inférieure 27 est disposée en dessous de la jupe 7. La pièce inférieure 27 comprend un bord périphérique externe 31, correspondant au bord périphérique externe 15, qui est agencé pour couvrir le bord périphérique interne 11 de la jupe 7 lors de son assemblage avec la pièce supérieure 29. En outre, ce bord périphérique externe 31 de la pièce inférieure 27 est agencé pour ne pas recouvrir le bord interne 17 des ailettes 9, et ainsi ne pas venir en appui sur la face inférieure desdites ailettes 9. Au contraire, la pièce supérieure 29 comprend un bord périphérique externe 33 agencé pour couvrir le bord périphérique interne 11 de la jupe 7, ainsi que la surface supérieure des ailettes 9 de manière à prendre appui, de préférence, au moins partiellement sur lesdits bords internes 17, sur le côté supérieur des ailettes 9. Une telle conception présente pour avantage, d'une part, d'assurer la souplesse de la voilure lors de sa fermeture selon laquelle elle se replie sur la pièce inférieure 27 de la base 3, ladite pièce inférieure 27, solidaire uniquement de la jupe souple 7, ne s'opposant pas à la fermeture de la voilure 5. Au contraire, lors du déploiement de la voilure 5 durant lequel la corolle s'ouvre, le bord périphérique externe 33 de la pièce supérieure 29 prend appui sur la face supérieure des ailettes 9 et forme une butée limitant l'ouverture de la corolle. Par ailleurs, la rigidité des ailettes 9 évite les risques de retournement de la voilure 5. Tel qu'illustré sur la figure 5, la pièce inférieure 27 comprend un bord périphérique externe 31 de forme circulaire. De même, tel qu'illustré sur la figure 3, le bord périphérique interne 11 de la jupe 7 est circulaire, son diamètre étant sensiblement inférieur à celui du bord périphérique externe 31 de la pièce inférieure 27. En outre, le diamètre du bord périphérique externe 31 est inférieur au diamètre correspondant à la position des bords internes 17 des ailettes 9.Figures 1, 2, 4 and 5 show the base 3 of the apparatus for aquatic gymnastics 1 according to the invention. Preferably, this base 3 consists of two pieces 27, 29. The first piece 27, illustrated in FIGS. 2 and 5, constitutes the lower part of the base 3. As illustrated in FIG. lower part 27 is disposed below the skirt 7. The lower part 27 comprises an outer peripheral edge 31, corresponding to the outer peripheral edge 15, which is arranged to cover the inner peripheral edge 11 of the skirt 7 during its assembly with the upper part 29. In addition, this outer peripheral edge 31 of the lower part 27 is arranged to not cover the inner edge 17 of the fins 9, and thus not bear against the underside of said fins 9. On the contrary, the upper part 29 comprises an outer peripheral edge 33 arranged to cover the inner peripheral edge 11 of the skirt 7, as well as the upper surface of the fins 9 so as to bear, of reference, at least partially on said inner edges 17, on the upper side of the fins 9. Such a design has the advantage, on the one hand, to ensure the flexibility of the wing when closed that it folds on the lower part 27 of the base 3, said lower part 27, integral only with the flexible skirt 7, not opposing the closing of the wing 5. On the contrary, during the deployment of the wing 5 during which the corolla s' opens, the outer peripheral edge 33 of the upper piece 29 bears on the upper face of the fins 9 and forms a stop limiting the opening of the corolla. Moreover, the rigidity of the fins 9 avoids the risk of flipping the wing 5. As illustrated in FIG. 5, the lower part 27 comprises an outer peripheral edge 31 of circular shape. Similarly, as shown in FIG. 3, the inner peripheral edge 11 of the skirt 7 is circular, its diameter being substantially smaller than that of the outer peripheral edge 31 of the lower part 27. In addition, the diameter of the peripheral edge outer 31 is smaller than the diameter corresponding to the position of the inner edges 17 of the fins 9.
Tel qu'illustré sur la figure 4, la pièce supérieure 29 comprend un bord périphérique externe 33 présentant la forme d'une étoile. La forme étoilée dispose d'un nombre de branches, c'est-à-dire d'un nombre d'extrémités angulaires 35 égales au nombre d'ailettes 9 présentes sur la voilure 5. Ces extrémités angulaires 35 sont aptes à prendre appui au moins sur la partie supérieure des ailettes 9, lors de l'assemblage des deux pièces 27, 29.As shown in FIG. 4, the upper piece 29 includes an outer peripheral edge 33 in the shape of a star. The star shape has a number of branches, that is to say a number of angular ends equal to the number of fins 9 present on the wing 5. These angular ends 35 are able to support the less on the upper part of the fins 9, during the assembly of the two parts 27, 29.
A ce titre, la pièce inférieure 27 et la pièce supérieure 29 sont agencées pour être assemblées l'une avec l'autre, de sorte que lors de leur assemblage, le bord périphérique interne 11 de la jupe 7 soit maintenu coincé entre lesdites deux pièces inférieure 27 et supérieure 29.As such, the lower part 27 and the upper part 29 are arranged to be assembled with each other, so that when they are assembled, the inner peripheral edge 11 of the skirt 7 is held wedged between said two parts. lower 27 and upper 29.
Selon une variante de conception, il est possible de concevoir une pièce supérieure 29 présentant un bord périphérique externe 33 de forme circulaire, plutôt que de forme étoilée. Dans ce cas, le diamètre du bord périphérique externe 33 est supérieur au diamètre du bord périphérique externe 31 de la pièce inférieure 27, ledit bord périphérique externe 33 de forme circulaire étant agencé pour prendre appui au moins sur la partie supérieure des ailettes 9, lors de l'assemblage entre les deux pièces inférieure 27 et supérieure 29. La pièce inférieure 27 et la pièce supérieure 29 comprennent toutes deux un bord périphérique interne 36a, 36b, de préférence de forme circulaire et présentant un diamètre identique, de sorte que lorsque les deux pièces sont assemblées, leurs bords périphériques internes 36a, 36b correspondent tel que cela est illustré sur les figures 1 et 2. Par ailleurs, la pièce inférieure 27 et la pièce supérieure 29 comprennent des clips d'assemblage 37, 39, illustrés sur les figures 4 et 5, les clips 37 sur la pièce inférieure 27 étant agencés pour s'encliqueter dans les clips 39 sur la pièce supérieure 29 afin de maintenir assemblées entre elles lesdites pièces. En outre, ces clips d'assemblage 37, 39 sont agencés sur ces pièces inférieure 27 et supérieure 29 en sorte de garantir le positionnement des extrémités angulaires 35 de la forme étoilée de la pièce supérieure 29 en vis-à-vis des ailettes 9 sur la voilure 5. Il est possible de prévoir en complément des moyens de positionnement de la pièce supérieure 29 ou de la pièce inférieure 27 selon une position bien définie sur la jupe 7, au moyen de « détrompeurs », pour garantir le positionnement des extrémités angulaires 35 de la forme étoilée au- dessus de la face supérieure des ailettes 9.According to a design variant, it is possible to design an upper piece 29 having an outer peripheral edge 33 of circular shape, rather than star shape. In this case, the diameter of the outer peripheral edge 33 is greater than the diameter of the outer peripheral edge 31 of the lower part 27, said outer peripheral edge 33 of circular shape being arranged to bear at least on the upper part of the fins 9, when the lower part 27 and the upper part 29 both comprise an inner peripheral edge 36a, 36b, preferably of circular shape and having an identical diameter, so that when the two pieces are assembled, their inner peripheral edges 36a, 36b correspond as shown in FIGS. 1 and 2. Furthermore, the lower piece 27 and the upper piece 29 comprise assembly clips 37, 39, illustrated on FIGS. Figures 4 and 5, the clips 37 on the lower part 27 being arranged to snap into the clips 39 on the upper part 29 to hold together said parts. In addition, these assembly clips 37, 39 are arranged on these lower 27 and upper 29 parts so as to ensure the positioning of the angular ends 35 of the star shape of the upper piece 29 vis-à-vis the fins 9 on the wing 5. It is possible to provide in addition to the positioning means of the upper part 29 or the lower part 27 in a well-defined position on the skirt 7, by means of "polarizers", to guarantee the positioning of the angular ends 35 of the star shape above the upper face of the fins 9.
Tel qu'illustré sur les figures 1, 2, 4 et 5, la base comprend une poignée centrale 41 apte à être maintenue avec la main ou à recevoir une pièce rapportée pour son maintien avec le pied. Cette poignée centrale 41 est constituée de deux demi poignées centrales 43, 45 l'une agencée sur la pièce inférieure 27 et l'autre sur la pièce supérieure 29, les deux demi poignées étant aptes à coopérer pour former la poignée centrale 41 lors du clipsage entre les deux pièces. Lorsque les deux pièces 27, 29 sont assemblées, les deux demi poignées centrales 43, 45 forment la poignée centrale 41 qui présente de préférence une forme cylindrique et ergonomique facilitant la préhension de l'appareil.As illustrated in Figures 1, 2, 4 and 5, the base comprises a central handle 41 adapted to be held with the hand or to receive an insert for its support with the foot. This central handle 41 consists of two central half handles 43, 45 one arranged on the lower part 27 and the other on the upper part 29, the two half handles being able to cooperate to form the central handle 41 during the clipping between the two rooms.
