Description

Arrière-plan de l'inventionBackground of the invention

La présente invention se rapporte au domaine général des appareils de musculation ou de rééducation physique. En général, ces appareils comprennent un support utilisateur permettant à un utilisateur de se positionner par rapport à l'appareil.The present invention relates to the general field of bodybuilding apparatus or physical rehabilitation. In general, these devices include a user support allowing a user to position themselves relative to the device.

Plus particulièrement, l'invention concerne les appareils mettant en oeuvre au moins un vérin hydraulique ou pneumatique porté par une longe supportant un bras d'exercice destiné à être actionné par l'utilisateur lorsqu'il est positionné sur le support utilisateur pour réaliser un exercice de musculation ou de rééducation.More particularly, the invention relates to devices using at least one hydraulic or pneumatic cylinder carried by a lanyard supporting an exercise arm intended to be actuated by the user when it is positioned on the user support to perform an exercise. bodybuilding or rehabilitation.

Ces appareils sont compacts et très simples d'utilisation mais ne permettent qu'un seul type d'exercice. Il est alors nécessaire de s'équiper avec plusieurs appareils dans le cas où le travail de plusieurs groupes musculaires est souhaité.These devices are compact and very simple to use but allow only one type of exercise. It is then necessary to equip with several devices in the case where the work of several muscle groups is desired.

Il existe également des appareils multifonctions permettant de travailler plusieurs groupes musculaires sur un même appareil. Ces appareils multifonction connus sont encombrants, lourds et bruyants. Ils utilisent généralement des piles de poids.There are also multifunction devices to work several muscle groups on the same device. These known multifunction devices are bulky, heavy and noisy. They usually use piles of weight.

On peut ainsi retrouver plusieurs accessoires fixés autour d'une pile de poids, le choix de l'exercice étant fait par le choix d'un accessoire particulier et d'un réglage sur l'appareil afin d'affecter les drisses permettant la manoeuvre des poids avec l'accessoire particulier. On peut rencontrer des appareils avec quatre piles de poids assemblées ensemble, généralement en carré, chaque pile de poids permettant d'alimenter un à deux accessoires particuliers de travail. Ces appareils sont donc particulièrement complexes à fabriquer et surtout à manipuler par le public. En général, il requièrent l'intervention d'un responsable de la manipulation des appareils ou du moins une formation de la personne susceptible de modifier l'exercice.It is thus possible to find several accessories fixed around a pile of weights, the choice of the exercise being made by the choice of a particular accessory and a setting on the apparatus in order to affect the halyards allowing the maneuvering of the weight with the particular accessory. We can meet devices with four stacks of weight assembled together, usually square, each pile of weight to feed one to two particular work accessories. These devices are particularly complex to manufacture and especially to handle by the public. In general, they require the intervention of a person in charge of the manipulation of the apparatus or at least a training of the person likely to modify the exercise.

Objet et résumé de l'inventionObject and summary of the invention

La présente invention a donc pour but principal de pallier les inconvénients des appareils connus en proposant un appareil de musculation ou de rééducation physique comprenant un support utilisateur permettant à un utilisateur de se positionner par rapport à l'appareil, l'appareil mettant en oeuvre au moins un dispositif de tension porté par une structure longitudinale longeant le dispositif de tension, dite longe supportant un bras d'exercice destiné à être actionné en rotation autour d'un axe dit axe d'exercice par l'utilisateur lorsque celui-ci est positionné sur le support utilisateur pour réaliser un exercice de musculation ou de rééducation, caractérisé en ce que, le dispositif de tension étant solidarisé à la longe par l'intermédiaire, d'un côté, d'un axe de rotation du dispositif de tension, et de l'autre côté, par l'intermédiaire d'un axe d'articulation porté par une biellette solidaire du bras d'exercice la longe portant le dispositif de tension est fixée au support utilisateur par l'intermédiaire d'un dispositif mécanique de réglage permettant de positionner la longe, par rotation autour d'un axe de rotation de la longe par rapport au support utilisateur, dit axe longe présentant une intersection avec la longe elle-même, et d'immobiliser la longe et le dispositif de tension dans au moins deux positions distinctes par rapport au support utilisateur dans lesquelles l'axe de rotation du bras d'exercice est aligné avec des axes articulaires du corps distincts, les deux positions permettant des exercices de musculation ou de rééducation de familles de groupes musculaires distinctes par actionnement du bras d'exercice.The present invention therefore has the main purpose of overcoming the disadvantages of known devices by proposing a weight training device or rehabilitation physical device comprising a user support allowing a user to position himself relative to the apparatus, the apparatus implementing at least one tensioning device carried by a longitudinal structure along the tensioning device, said lanyard supporting an exercise arm intended to be actuated in rotation around an axis called the axis of exercise by the user when it is positioned on the user support to perform a weight training or rehabilitation exercise, characterized in that , the tensioning device being secured to the lanyard via, on one side, an axis of rotation of the tensioning device, and on the other side, via a hinge pin carried by a rod integral with the arm of exercise the lanyard carrying the tensioning device is fixed to the user support by means of a mechanical adjustment device for positioning the lanyard, by rotation about an axis of rotation of the lanyard relative to the user support, said lanyard having an intersection with the lanyard itself, and immobilizing the lanyard and the tensioning device in at least two distinct positions relative to the user support in which the axis rotation of the arm of exercise is aligned with separate articular axes of the body, the two positions allowing exercises of bodybuilding or rehabilitation of families of distinct muscle groups by actuation of the arm of exercise.

L'invention consiste ainsi à mettre en oeuvre un dispositif de tension associé à un dispositif mécanique de réglage permettant la réalisation d'un appareil de musculation multifonctions. Par un procédé mécanique, il est possible de faire passer le dispositif de tension d'une position à une autre. Cela permet de réaliser, sur un même appareil et avec un seul vérin, plusieurs exercices sur différents groupes musculaires en ne changeant pas de support utilisateur. L'objectif est en effet selon l'invention de positionner le dispositif de tension en différentes positions par rapport à ce même support utilisateur pour aligner l'axe du bras d'exercice avec différents axes articulaires.The invention thus consists in implementing a tensioning device associated with a mechanical adjustment device enabling the realization of a multifunctional bodybuilding apparatus. By a mechanical method, it is possible to move the tension device from one position to another. This allows to perform, on the same device and with a single jack, several exercises on different muscle groups by not changing user support. The objective is indeed according to the invention to position the tension device in different positions relative to the same user support to align the axis of the exercise arm with different articular axes.

Le brevet repose ainsi sur la mise en oeuvre d'un dispositif de tension, notamment un vérin, dans le cadre d'un appareil de musculation. L'appareil, suivant la position de départ du vérin, permet de réaliser plusieurs exercices. Il est en outre possible de placer un ou plusieurs vérins sur l'appareil selon l'invention de façon à multiplier les exercices.The patent thus relies on the implementation of a tensioning device, in particular a jack, in the context of a weight training device. The apparatus, according to the starting position of the jack, makes it possible to carry out several exercises. It is also possible to place one or more jacks on the apparatus according to the invention so as to multiply the exercises.

L'intérêt de l'invention est de pouvoir associer, dans un même appareil, l'aspect pratique, silencieux et compact d'un appareil à vérins ou structure élastique avec la possibilité de réaliser plusieurs exercices sur le même appareil. Cette cinématique est facilement mise en oeuvre par l'utilisateur grâce à l'invention parmi un nombre limité de positions de la longe portant le vérin par rapport au support utilisateur. La longe qui longe le dispositif de tension est articulée elle-même en rotation par rapport au support utilisateur autour d'un axe sécant avec la longe. Avec l'invention, l'utilisateur modifie donc directement la position du dispositif de tension par rapport au support utilisateur par une rotation propre de ce dispositif de tension. En effet, selon l'invention, Le dispositif de tension est longé par la longe. Il est plus précisément solidarisé avec la longe entre un axe de rotation du dispositif de tension et un axe d'articulation porté par une biellette (ou d'ailleurs d'un autre élément permettant une excentricité : came, notamment dans le cas de l'utilisation d'une structure élastique, etc...), solidaire du bras d'exercice lui-même supporté autour d'un axe de rotation par la longe. Ainsi, le dispositif de tension est donc articulé en rotation autour d'un axe qui est sensiblement sécant avec lui-même, ce qui est un avantage majeur de l'invention qui permet un pivotement simple et rapide du dispositif de tension par rapport au support utilisateur.The advantage of the invention is to be able to combine, in a same device, the practical, silent and compact appearance of a device with jacks or elastic structure with the possibility of performing several exercises on the same device. This kinematics is easily implemented by the user thanks to the invention among a limited number of positions of the lanyard carrying the jack relative to the user support. The lanyard which runs along the tensioning device is articulated itself in rotation relative to the user support around an axis intersecting with the lanyard. With the invention, the user therefore directly modifies the position of the tensioning device relative to the user support by a proper rotation of this tensioning device. Indeed, according to the invention, the tension device is skirted by the lanyard. It is more precisely secured to the lanyard between an axis of rotation of the tensioning device and a hinge axis carried by a link (or indeed another element allowing an eccentricity: cam, particularly in the case of the use of an elastic structure, etc ...), integral with the exercise arm itself supported around an axis of rotation by the lanyard. Thus, the tension device is articulated in rotation around an axis which is substantially secant with itself, which is a major advantage of the invention which allows a simple and rapid pivoting of the tension device relative to the support user.

En permettant l'alignement de l'axe d'exercice avec différents axes articulaires de l'utilisateur positionné sur le support utilisateur, on autorise plusieurs types d'exercices. Aucune modification de configuration du support utilisateur n'est requise. En outre, le réglage de position par une rotation directe du dispositif de tension longé et porté par la longe est simple à appréhender par l'utilisateur.By allowing the alignment of the exercise axis with different articular axes of the user positioned on the user support, several types of exercises are authorized. No user support configuration changes are required. In addition, the position adjustment by a direct rotation of the tension device lined and carried by the lanyard is easy to apprehend by the user.

La présence sur le dispositif mécanique de réglage d'éléments permettant l'immobilisation et donc le verrouillage en position est donc une caractéristique essentielle.The presence on the mechanical device for adjusting the elements allowing the immobilization and thus the locking in position is therefore an essential characteristic.

Les dispositifs de tension susceptibles d'être utilisés selon l'invention comprennent les éléments élastiques, ressorts, élastiques, etc. ainsi que tous les types de vérins hydrauliques ou pneumatiques simple effet ou double effet. On remarque ici que l'invention est particulièrement pertinente avec un vérin hydraulique ou une structure élastique, soit un ressort, soit un élastique, puisque ces dispositifs de tension sont généralement passifs et ne nécessitent pas d'apport d'énergie ce qui est une caractéristique très intéressante en combinaison avec les moyens de l'invention puisque, sans énergie, on parvient à la fabrication d'un appareil multifonction.The voltage devices that can be used according to the invention comprise the elastic elements, springs, elastics, etc. as well as all types of single or double acting hydraulic or pneumatic cylinders. We note here that the invention is particularly relevant with a hydraulic cylinder or an elastic structure, either a spring or an elastic, since these voltage devices are generally passive and do not require energy input which is a very interesting feature in combination with the means of the invention since, without energy, it is possible to manufacture a multifunction device.

En effet l'invention permet de placer la longe, structure longitudinale longeante, en plusieurs positions grâce à un déplacement de la longe permettant le positionnement de l'axe de rotation du bras d'exercice, dit axe d'exercice, en plusieurs positions physiologiques. En effet, pour permettre l'exercice, cet axe d'exercice doit correspondre à l'axe articulaire du membre travaillé : coude pour les biceps et triceps, genoux pour les quadri et ischios, épaule pour le travail des bras, le cas échéant lors de l'adjonction d'une longe supplémentaire à l'arrière du siège. Donc, selon l'invention, les différentes positions angulaires de la structure longitudinale longeante permettent de travailler le bas ou le haut du corps suivant les différents axes articulaires.Indeed the invention makes it possible to place the lanyard, longitudinal longitudinal structure, in several positions through a displacement of the lanyard allowing the positioning of the axis of rotation of the exercise arm, said axis of exercise, in several physiological positions. . Indeed, to allow exercise, this axis of exercise must correspond to the articular axis of the member worked: elbow for the biceps and triceps, knees for the quadri and ischios, shoulder for the work of the arms, if necessary during the addition of an extra lanyard to the back of the seat. Thus, according to the invention, the different angular positions of the longitudinal longitudinal structure make it possible to work the lower or the upper part of the body along the different articular axes.

Dans une réalisation préférentielle, le dispositif de tension est choisi parmi les vérins hydrauliques ou pneumatiques, simple ou double effet, et les structures élastiques.In a preferred embodiment, the tensioning device is chosen from hydraulic or pneumatic cylinders, single or double acting, and elastic structures.

Un tel choix de dispositif de tension permet d'atteindre une grande compacité de l'appareil.Such a choice of tension device makes it possible to achieve a great compactness of the apparatus.

Dans une autre réalisation, le dispositif de tension comprend une sangle reliée à une charge, la sangle étant fixée à la longe par l'intermédiaire d'une biellette solidaire du bras d'exercice à l'extrémité de laquelle elle est fixée et venant glisser et pivoter autour d'un axe de rotation de la sangle confondu avec l'axe longe.In another embodiment, the tensioning device comprises a strap connected to a load, the strap being fixed to the lanyard by means of a link secured to the exercise arm at the end of which it is fixed and sliding and pivot about an axis of rotation of the strap coincides with the axis lanyard.

Dans ce cas la sangle est typiquement reliée à une pile de poids. Puisque l'axe de rotation du dispositif de tension est ici confondu avec l'axe longe, la modification de position de la longe est réalisée sans aucun changement de longueur de la sangle entre l'axe de rotation du dispositif de tension et l'axe d'articulation qui est ici un point de fixation de la sangle sur la biellette.In this case the strap is typically connected to a weight stack. Since the axis of rotation of the tensioning device here coincides with the lanyard axis, the change in position of the lanyard is achieved without any change in length of the strap between the axis of rotation of the tensioning device and the axis. articulation which is here a point of attachment of the strap on the link.

On note ici qu'une came à laquelle la sangle serait fixée pourrait aussi être utilisée en lieu et place de la biellette, une telle came permettant l'enroulement de la sangle autour de la came et une répartition améliorée de l'effort.It is noted here that a cam to which the strap would be attached could also be used instead of the rod, such a cam allowing the winding of the strap around the cam and an improved distribution of effort.

Dans une réalisation préférentielle, l'axe longe est horizontal.In a preferred embodiment, the longitudinal axis is horizontal.

Une telle caractéristique autorise à faire pivoter le dispositif de tension monté sur la structure longitudinale le longeant, la longe, dans un plan vertical latéral par rapport au support utilisateur. L'encombrement de l'appareil n'est ainsi pas modifié par la rotation de la longe portant le dispositif de tension tout en assurant une multiplication des fonctionnalités de l'appareil.Such a feature allows to rotate the tension device mounted on the longitudinal structure along the lanyard in a lateral vertical plane relative to the user support. The size of the device is thus not changed by the rotation of the lanyard carrying the tension device while ensuring a multiplication of the features of the device.

Selon une réalisation avantageuse, le dispositif mécanique de réglage comprend une flasque perforée en au moins autant d'endroits que de positions prises par la longe, cette flasque étant destinée à coopérer avec au moins un cliquet destiné à se loger dans l'une des perforations de la flasque, la flasque étant fixe par rapport à la longe alors que le cliquet est fixe par rapport au support utilisateur ou inversement.According to an advantageous embodiment, the mechanical adjustment device comprises a perforated flange in at least as many places as positions taken by the lanyard, this flange being intended to cooperate with at least one pawl intended to be housed in one of the perforations of the flange, the flange being fixed relative to the lanyard while the pawl is fixed relative to the user support or vice versa.

Cette réalisation pratique est simple et aisée de manipulation.This practical realization is simple and easy to handle.

Selon une réalisation préférentielle de l'appareil selon l'invention, le support utilisateur étant constitué d'une assise et d'un dossier et la longe étant d'une longueur sensiblement identique à celle du vérin, la longe est articulée en rotation autour d'un axe longe horizontal perpendiculaire au plan médian de l'appareil, cet axe longe étant situé au niveau de l'assise.According to a preferred embodiment of the apparatus according to the invention, the user support consisting of a seat and a backrest and the lanyard being of a length substantially identical to that of the cylinder, the lanyard is articulated in rotation around a horizontal lenght axis perpendicular to the median plane of the device, this lanyard being located at the level of the seat.

Cette réalisation autorise de positionner les éléments de manière à pouvoir faire travailler le haut et le bas du corps avec le même appareil. Ainsi, le même ensemble assise-dossier est utilisé par l'utilisateur pour le haut et le bas du corps. L'appareil est donc très polyvalent et compact et évite l'installation et l'achat de deux appareils distincts pour le haut du corps et pour le bas qui auraient chacun leur ensemble assise-dossier propre. Le positionnement de l'axe longe au niveau de l'assise permet de faire basculer le dispositif de tension entre une position haute où le dispositif de tension est orienté vers le haut, la biellette et l'axe d'exercice se trouvant alors au dessus de l'assise, et une position basse où le dispositif de tension est orienté vers le bas, la biellette et l'axe d'exercice se trouvant alors sous l'assise.This embodiment makes it possible to position the elements so as to be able to work the upper and lower body with the same device. Thus, the same seat-back assembly is used by the user for the upper and lower body. The device is very versatile and compact and avoids the installation and purchase of two separate devices for the upper body and for the bottom which would each have their own seat-record clean. The positioning of the axis running along the seat makes it possible to tilt the tensioning device between a high position where the tensioning device is oriented upwards, the link and the axis of exercise then being at the top. of the seat, and a low position where the tensioning device is oriented downwards, the rod and the axis of exercise then being under the seat.

Préférentiellement, l'axe d'articulation de la longe est situé entre 1/5 et 2/5 de sa longueur.Preferably, the axis of articulation of the lanyard is between 1/5 and 2/5 of its length.

Cette caractéristique autorise une longueur adaptée du vérin tout en assurant les positions utiles pour la polyvalence de l'appareil.This characteristic allows a suitable length of the cylinder while ensuring the positions useful for the versatility of the device.

Encore préférentiellement, la position de l'axe longe sur la longe et les positions de la longe sont telles qu'une partie la plus longue de la longe vient se placer entre 4 et 18° du plan d'assise pour l'exercice du bas du corps et entre 95° et 125° du plan d'assise pour l'exercice du haut du corps.Even more preferably, the position of the shaft runs along the lanyard and the positions of the lanyard are such that a longest part of the lanyard is placed between 4 and 18 ° of the seating plane for the lower exercise. of the body and between 95 ° and 125 ° of the plane of seat for the exercise of the upper body.

Ces positions angulaires sont celles qui permettent de faire correspondre l'axe de bras d'exercice aux axes articulaires.These angular positions are those that make it possible to match the axis of the exercise arm to the articular axes.

Selon une caractéristique particulière de l'invention, le bras d'exercice est supporté par la longe par l'intermédiaire d'un dispositif de modification du mouvement angulaire du bras d'exercice permettant de positionner le bras d'exercice dans plusieurs positions permettant des exercices de musculation ou de rééducation de groupes musculaires distincts par actionnement en rotation du bras d'exercice.According to a particular characteristic of the invention, the exercise arm is supported by the lanyard by means of a device for modifying the angular movement of the exercise arm enabling the exercise arm to be positioned in several positions allowing exercises of bodybuilding or rehabilitation of distinct muscle groups by actuation in rotation of the exercise arm.

Cette caractéristique par ailleurs déjà connue autorise, en combinaison avec l'invention, une encore plus grande modularité de l'appareil puisque le bras d'exercice peut être positionné de manière diverses en fonction de l'exercice mais aussi de la taille de l'utilisateur notamment. Avantageusement, la modification du mouvement angulaire du bras d'exercice se fait par rotation autour de l'axe d'exercice. Ainsi, pour une même position de l'ensemble longe/dispositif de tension, la position du bras d'exercice peut être modifiée aussi par l'utilisateur pour qu'il réalise, sur le même appareil et pour la même position du dispositif de tension, des exercices spécifiques pour plusieurs muscles : typiquement, sur le haut du corps, les abdominaux et les triceps. On comprend bien ici l'intérêt de l'invention de multiplier encore davantage les multiples fonctionnalités d'une machine en ajoutant une articulation supplémentaire, cette articulation entrainant spécifiquement une modification de position du dispositif de tension lui-même grâce à la structure longitudinale longeant ce dispositif de tension elle -même articulée en rotation par rapport au support utilisateur. Cette modification de position du dispositif de tension lui-même en rotation par rapport au support utilisateur rend possible une multiplication particulièrement avantageuse des fonctionnalités de l'appareil.This already known feature allows, in combination with the invention, an even greater modularity of the device since the exercise arm can be positioned in various ways depending on the exercise but also the size of the particular user. Advantageously, the modification of the angular movement of the exercise arm is done by rotation about the axis of exercise. Thus, for the same position of the lanyard / tension device assembly, the position of the exercise arm can also be modified by the user to perform on the same apparatus and for the same position of the tensioning device. , specific exercises for several muscles: typically, on the upper body, abdominals and triceps. It is well understood here the interest of the invention to multiply even more the multiple functionalities of a machine by adding an additional articulation, this articulation resulting specifically a modification of position of the tensioning device itself thanks to the longitudinal structure along this tension device itself articulated in rotation relative to the user support. This change in position of the tension device itself in rotation relative to the user support makes possible a particularly advantageous multiplication of the features of the device.

Selon une réalisation avantageuse, le dispositif de modification du mouvement angulaire du bras d'exercice comprend un disque perforé en au moins autant d'endroits que de positions prises par le bras d'exercice pour la modification du mouvement angulaire, ce disque étant destiné à coopérer avec au moins un cliquet, fixe par rapport au bras d'exercice, destiné à se loger dans l'une des perforations du disque, l'ensemble disque/bras d'exercice étant monté en rotation par rapport à la longe pour la réalisation des exercices.According to an advantageous embodiment, the device for modifying the angular movement of the exercise arm comprises a perforated disc in at least as many places as positions taken by the exercise arm for the modification of the angular movement, this disc being intended to cooperate with at least one ratchet, fixed relative to the exercise arm, intended to be housed in one of the perforations of the disc, the disk / exercise arm assembly being mounted in rotation with respect to the lanyard for the realization of the exercises.

Un tel réglage permet une grande souplesse et une résistance à l'effort tout à fait suffisante pour un appareil de musculation ou de rééducation.Such an adjustment allows great flexibility and resistance to effort quite sufficient for a weight training or rehabilitation device.

Préférentiellement, le bras d'exercice peut prendre des positions angulaires successives à 15° les unes des autres.Preferably, the exercise arm can take successive angular positions at 15 ° from each other.

Cette caractéristique assure une adaptation correcte du mouvement angulaire pour des personnes de tailles, de forces et de morphologies différentes tout en assurant une simplicité de réglage.This feature ensures correct angular movement adaptation for people of different sizes, strengths and morphologies while providing easy adjustment.

Selon une caractéristique préférentielle de l'invention, le dispositif de tension étant simple effet, le déplacement en rotation du bras d'exercice pour la modification du mouvement angulaire entraine une modification de la position relative du dispositif de tension par rapport à la longe.According to a preferred feature of the invention, the tension device being a simple effect, the rotational movement of the exercise arm for the modification of the angular movement causes a change in the relative position of the tension device relative to the lanyard.

Cette caractéristique autorise de changer l'axe de la force générée par le vérin. Cela permet de régler l'appareil de manière à ce que l'effort de l'utilisateur puisse être dans un sens de rotation ou dans l'autre autour de l'axe de rotation du bras d'exercice à l'extrémité de la longe.This feature makes it possible to change the axis of the force generated by the jack. This allows the device to be adjusted so that the user's effort can be in one direction of rotation or the other around the axis of rotation of the exercise arm at the end of the lanyard. .

Cela permet d'augmenter encore le nombre d'exercice susceptible d'être pratiqués avec l'appareil selon l'invention.This makes it possible to further increase the number of exercises that can be performed with the apparatus according to the invention.

Pour cela, le dispositif de tension est raccordé à un ou plusieurs systèmes mécaniques réglables et modulables, cames, biellettes etc mobiles en rotation et assurant la mise en position adéquate du dispositif de tension par rapport à la longe.For this purpose, the tensioning device is connected to one or more adjustable and adjustable mechanical systems, cams, rods, etc. that are movable in rotation and ensuring that the tensioning device is properly positioned relative to the lanyard.

Ainsi, dans une réalisation, une biellette réalise un lien mécanique entre une extrémité du dispositif de tension et le point d'attache du bras d'exercice par rapport à la longe, cette biellette étant destinée à changer de position de part et d'autre de la ligne médiane de la longe en fonction du sens de rotation de l'exercice souhaité. Cette caractéristique qui permet de changer la position latérale relative du dispositif de tension par rapport à la structure longitudinale qui longe ce dispositif de tension permet de multiplier les exercices réalisables avec l'appareil selon l'invention.Thus, in one embodiment, a connecting rod makes a mechanical link between one end of the tensioning device and the point of attachment of the exercise arm relative to the lanyard, this link being intended to change position on either side the center line of the lanyard depending on the direction of rotation of the desired exercise. This characteristic which makes it possible to change the relative lateral position of the tensioning device with respect to the longitudinal structure which runs along this tensioning device makes it possible to multiply the exercises that can be performed with the apparatus according to the invention.

Selon une caractéristique intéressante de l'invention, le bras d'exercice porte au moins un rouleau à son extrémité opposée à l'axe d'exercice, la position de ce rouleau par rapport au bras d'exercice est également réglable par rotation autour d'un axe, dit axe rouleau, placé en extrémité du bras d'exercice.According to an advantageous characteristic of the invention, the exercise arm carries at least one roller at its end opposite to the axis of exercise, the position of this roller relative to the exercise arm is also adjustable by rotation around an axis, called the roller axis, placed at the end of the exercise arm.

Cela autorise de régler finement l'appareil en fonction de la taille et de la morphologie de l'utilisateur. Enfin, dans une réalisation encore plus polyvalente, le dispositif selon l'invention comprend plusieurs ensembles longe/dispositif de tension/bras d'exercice répartis autour du support utilisateur.This allows finely tuning the device according to the size and morphology of the user. Finally, in an even more versatile embodiment, the device according to the invention comprises several sets of lanyard / tension device / exercise arm distributed around the user support.

Cela autorise de définir des cinématiques mécaniques multiples pour positionner des dispositifs de tension dans différentes positions, la position du support utilisateur restant quant à elle inchangée et commune pour tous les exercices.This makes it possible to define multiple mechanical kinematics for positioning voltage devices in different positions, the position of the user support remaining unchanged and common for all exercises.

L'invention utilise une longe 3 portant un vérin 4 et sur laquelle est soudée une flasque 5 d'articulation. On remarque ici que l'invention est décrite avec l'utilisation d'un vérin. Néanmoins, on comprend bien que celui-ci peut être remplacé par un élément élastique, que ce soit une ou des sangles élastiques ou un ressort qui réaliserait la même fonction de tension s'opposant à l'exercice des efforts de l'utilisateur.The invention uses a lanyard 3 carrying a jack 4 and on which is welded a hinge flange 5. It is noted here that the invention is described with the use of a jack. Nevertheless, it is understood that it can be replaced by an elastic element, whether it is one or elastic straps or a spring that would perform the same tension function opposing the exercise of the efforts of the user.

Selon l'invention, la longe 3 est articulée en rotation autour d'un axe, dit axe longe 6. L'axe longe 6 présente une intersection avec la longe 3 elle-même. Il est en outre perpendiculaire à celle-ci. Comme l'axe longe 6 est en outre horizontal ici, la longe 3 pivote en restant dans un plan vertical, ce qui est un grand avantage d'un point de vue de la compacité de l'appareil.According to the invention, the lanyard 3 is articulated in rotation about an axis, said lanyard 6. The axis lanyard 6 has an intersection with the lanyard 3 itself. It is also perpendicular to it. As the lanyard 6 is furthermore horizontal here, the lanyard 3 pivots while remaining in a vertical plane, which is a great advantage from a point of view of the compactness of the apparatus.

La flasque d'articulation 5 comprend ici deux trous 7a et 7b, ici non visible, qui servent à placer la longe dans les deux positions angulaires selon l'invention, ici une pour le travail du haut du corps et l'autre pour le bas du corps.The hinge flange 5 here comprises two holes 7a and 7b, here not visible, which serve to place the lanyard in the two angular positions according to the invention, here one for the work of the upper body and the other for the bottom from the body.

On remarque ici que la flasque d'articulation 5 peut comprendre un nombre plus important de trous permettant de placer la longe 3 dans un nombre plus important de positions. La longe 3 est donc mobile en rotation autour de l'axe longe 6 et elle peut être bloquée en position dans sa rotation par un cliquet 11 qui se place dans un des deux trous. Ce cliquet 11 est actionné par l'utilisateur.It is noted here that the hinge flange 5 may comprise a larger number of holes for placing the lanyard 3 in a larger number of positions. The lanyard 3 is rotatable about the lanyard axis 6 and can be locked in position in its rotation by a pawl 11 which is placed in one of the two holes. This pawl 11 is actuated by the user.

Le vérin 4 est avantageusement fixé à la longe 3 par l'intermédiaire, d'un côté, d'un axe de rotation du vérin 8a, et de l'autre côté, par l'intermédiaire d'un axe d'articulation 8b porté par une biellette 9 montée solidaire et fixe avec un axe dit axe d'exercice 10 apte à pivoter par rapport à la longe 3. L'axe d'exercice 10 est en outre solidaire d'un disque de réglage 12 perforé tous les 15°.The jack 4 is advantageously fixed to the lanyard 3 via, on one side, an axis of rotation of the jack 8a, and on the other side, via a hinge pin 8b carried by a connecting rod 9 fixedly mounted and fixed with an axis called axis of exercise 10 adapted to pivot relative to the lanyard 3. The axis of exercise 10 is further secured to a setting disc 12 perforated every 15 ° .

Pratiquement la biellette 9 est soudée à l'axe 10 qui est, lui, soudé au disque 12. Idéalement le vérin est double effet et peut travailler en étirement ou en compression. Dans la configuration de la figure 1, la force nécessaire à sortir la tige du vérin est plus grande que celle nécessaire à la rentrer. On notera que cette force est avantageusement réglable sur le vérin.Practically the rod 9 is welded to the axis 10 which is welded to the disk 12. Ideally the cylinder is double acting and can work in stretching or compression. In the configuration of the figure 1 the force required to pull the rod out of the jack is greater than that required to retract it. It will be noted that this force is advantageously adjustable on the jack.

La présence du disque de réglage 12 permet de modifier le déplacement angulaire du bras d'exercice 20 par mise en position en rotation du bras d'exercice 20, cette position étant bloquée à l'aide d'un cliquet 13, solidaire du bras d'exercice, qui vient s'engager dans une des perforations du disque 12. Le bras d'exercice 20 est alors rendu solidaire de l'axe de bras d'exercice 10 qui pivote par rapport à la longe 3 avec la biellette 9.The presence of the adjustment disc 12 makes it possible to modify the angular displacement of the exercise arm 20 by placing the exercise arm 20 in a rotational position, this position being blocked by means of a pawl 13, integral with the arm exercise, which is engaged in one of the perforations of the disk 12. The exercise arm 20 is then secured to the axis of the exercise arm 10 which pivots relative to the lanyard 3 with the rod 9.

Avantageusement, pour permettre un réglage en fonction de la taille et de la morphologie de l'utilisateur et assurer son confort, l'appareil comprend un porte rouleau ou rondin 14 monté en rotation autour d'un axe 15 placé en extrémité du bras d'exercice 20. Ce réglage permet de trouver une position d'exercice confortable, le support rondin 14 étant équipé de deux rondins en mousse.Advantageously, to allow adjustment according to the size and morphology of the user and ensure its comfort, the apparatus comprises a roller or log holder 14 rotatably mounted about an axis 15 placed at the end of the arm of exercise 20. This setting makes it possible to find a comfortable exercise position, the round support 14 being equipped with two foam logs.

Un disque 16 perforé ici aussi tous les 15° est soudé au porte rondin 14. La position du disque 16 par rapport au bras d'exercice 20 est fixée grâce à un cliquet 17, solidaire du support rondin 14 qui s'engage dans un des trous du disque 16.A disc 16 perforated here also every 15 ° is welded to the round door 14. The position of the disc 16 relative to the exercise arm 20 is fixed by means of a pawl 17 secured to the round support 14 which engages in one of the holes of the disc 16.

Sur la figure 1, l'appareil est réglé pour la réalisation d'exercices sur les ischios.On the figure 1 , the device is set to perform exercises on the ischios.

Grâce à la flasque 5 et au cliquet 11, la longe 3 et le bras d'exercice 20 sont positionnés par l'utilisateur presque dans l'alignement l'un de l'autre. L'utilisateur est assis sur l'assise 2 et appuie avec l'arrière du pied ou le bas du mollet sur les rondins 14 et les pousse en rotation vers le bas. Le bras d'exercice 20 est entraîné en rotation ainsi que le disque 12 solidarisé avec la biellette 9. Dans ce mouvement, il entraine alors la sortie de la tige de vérin ce qui oblige à un effort permettant le travail des ischios. Cela permet en effet de lutter contre la force du vérin et de pratiquer l'exercice voulu. Une sangle, non représentée, au niveau des rondins permet avantageusement à l'utilisateur de ramener l'ensemble en position de départ.With the flange 5 and the pawl 11, the lanyard 3 and the exercise arm 20 are positioned by the user almost in alignment with each other. The user sits on the seat 2 and presses with the back of the foot or the bottom of the calf on the logs 14 and pushes them in rotation downwards. The exercise arm 20 is rotated and the disc 12 secured to the rod 9. In this movement, it then drives the output of the cylinder rod which forces a force allowing the work of the ischios. This makes it possible to fight against the force of the jack and to practice the desired exercise. A strap, not shown, at the level of the logs advantageously allows the user to bring the assembly back to the starting position.

La figure 2 représente une configuration de l'appareil pour l'exercice des quadriceps. Le cliquet 11 est toujours dans le trou 7a de la flasque 5 mais la position du bras d'exercice a été modifiée. En conservant la même position de vérin que pour la fonction ischios, l'utilisateur tire sur le cliquet 13 et positionne le bras d'exercice 20 dans la position adéquate pour cet exercice. Avantageusement des repères seront ajoutés pour faciliter la mise en position. Il relâche le cliquet 13 pour solidariser le bras d'exercice 20 et la longe 3.The figure 2 represents a device configuration for quadriceps exercise. The pawl 11 is still in the hole 7a of the flange 5 but the position of the exercise arm has been modified. Keeping the same jack position as for the ischios function, the user pulls on the pawl 13 and positions the exercise arm 20 in the proper position for this exercise. Advantageously, marks will be added to facilitate positioning. It releases the pawl 13 to secure the exercise arm 20 and the lanyard 3.

L'utilisateur est assis sur le siège, le plat du pied ou le bas du tibia en appui sur les rondins. Il place ses jambes derrières les rondins avec le bas de ses tibias en appui sur ceux-ci. L'utilisateur pousse les rondins 14 vers le haut et entraine en rotation autour de l'axe 10 le bras d'exercice 20 et, de proche en proche, le disque 12 et donc la sortie de la tige du vérin 4 ce qui nécessite un effort permettant le travail des quadriceps. Le retour en position de départ est aidé par une sangle non représentée. L'utilisateur pousse sur les rondins en luttant donc contre la résistance du vérin 4 par entrainement en rotation du bras d'exercice 20. Celui-ci solidaire du disque 12 entraîne la biellette 9 en rotation et donc la tête de vérin.The user is seated on the seat, the foot plate or the bottom of the tibia resting on the logs. He places his legs behind the logs with the bottom of his shins resting on them. The user pushes the logs 14 upwards and rotates around the axis 10 the exercise arm 20 and, step by step, the disc 12 and thus the output of the rod of the jack 4, which requires a effort allowing the work of the quadriceps. The return to the starting position is assisted by a strap not shown. The user pushes on the logs thus fighting against the resistance of the jack 4 by rotating the exercise arm 20. The latter secured to the disk 12 drives the rod 9 in rotation and thus the cylinder head.

Pour passer en position exercice du haut du corps, en tirant sur le cliquet 11, l'utilisateur peut déplacer la longe 3 et entrainer l'ensemble longe/vérin en rotation autour de l'axe 6. Il relâche le cliquet 11 dans le trou 7b prévu sur la flasque 5 pour le travail du haut du corps.To move to the exercise position of the upper body, by pulling on the ratchet 11, the user can move the lanyard 3 and cause the lanyard / cylinder assembly to rotate about the axis 6. It releases the ratchet 11 into the hole 7b provided on the flange 5 for the work of the upper body.

Comme représenté sur les figures 3A et 3B, il place ensuite en position le bras d'exercice 20 par rapport à la longe 3 dans une position angulaire adaptée au travail, par exemple ici les abdominaux hauts. La position angulaire pourra être celle, presque verticale, représentée sur la figure 3 ou une position angulaire proche de celle-ci. Ensuite l'utilisateur relâche le cliquet 13.As shown on Figures 3A and 3B he then places the exercise arm 20 in position relative to the lanyard 3 in an angular position adapted to the work, for example here the high abs. The angular position may be that, almost vertical, represented on the figure 3 or an angular position close to it. Then the user releases the pawl 13.

L'utilisateur peut également ajuster la position des rondins 14 par l'intermédiaire du cliquet 17 et du disque 16.The user can also adjust the position of the logs 14 via the pawl 17 and the disc 16.

Dans la position abdominaux hauts, l'utilisateur est assis dans l'appareil et il positionne les rondins grâce au cliquet 17 et au disque 16. Il place son torse en appui sur les rondins. En contractant ses abdominaux, il entraine en rotation le bras d'exercice 20 avec l'axe de bras d'exercice 10. Grâce au cliquet 13, la rotation du bras d'exercice 20 entraine la rotation du disque 12, de l'axe d'exercice 10 et de lutter contre la force du vérin, de la biellette 9 qui entraine la sortie de la tige du vérin 4. L'utilisateur ramène ensuite l'ensemble à la position de départ.In the high abdominal position, the user sits in the apparatus and positions the logs with the ratchet 17 and the disk 16. He places his torso in support on the logs. By contracting his abs, he rotates the exercise arm 20 with the axis of the exercise arm 10. With the ratchet 13, the rotation of the exercise arm 20 causes the rotation of the disc 12, the axis 10 and exercise against the force of the cylinder, the rod 9 which causes the output of the cylinder rod 4. The user then returns the assembly to the starting position.

Ensuite, pour permettre un travail des triceps, ainsi que représenté sur les figures 4A et 4B, en conservant la position de la longe 3 dans la position exercice du haut du corps de la figure 3, l'utilisateur change l'angle entre la longe 3 et le bras d'exercice 20 par le système du cliquet 13 et du disque 12. Il est alors possible de travailler les triceps. L'utilisateur entraine en rotation le bras d'exercice 20 en poussant sur les rondins avec les bras.Then, to allow triceps work, as well as represented on the Figures 4A and 4B , keeping the position of the lanyard 3 in the exercise position of the upper body of the figure 3 , the user changes the angle between the lanyard 3 and the exercise arm 20 by the ratchet system 13 and the disc 12. It is then possible to work the triceps. The user rotates the exercise arm 20 by pushing on the logs with the arms.

Pour faire travailler les biceps, et ainsi que représenté sur les figures 5A et 5B, en plus de modifier l'angle entre la longe 3 et le bras d'exercice 20, l'utilisateur change le sens de rotation du bras d'exercice donnant lieu à résistance du vérin.To work the biceps, and as represented on the Figures 5A and 5B , in addition to changing the angle between the lanyard 3 and the exercise arm 20, the user changes the direction of rotation of the exercise arm giving rise to resistance of the jack.

L'utilisateur vient aussi avantageusement placer les rondins à environ 20 cm de ses genoux grâce au cliquet 17 et au disque 16.Pour cela, l'utilisateur tire sur le cliquet 13 et déplace le vérin et sa tige entre la position représentée sur la figure 4 et la position représentée sur la figure 5 en faisant tourner la biellette 9, sur laquelle une manivelle peut être ajoutée à cet effet, puis il relâche le cliquet 13 pour solidariser à nouveau le bras d'exercice 20 et le disque 12.The user also advantageously places the logs about 20 cm from his lap thanks to the pawl 17 and the disc 16. For this, the user pulls on the pawl 13 and moves the jack and its rod between the position shown on the drawing. figure 4 and the position represented on the figure 5 by rotating the rod 9, on which a crank may be added for this purpose, then it releases the pawl 13 to secure the exercise arm 20 and the disk 12 again.

L'utilisateur peut alors placer ses mains sous les rondins et ramener ses bras vers le torse pour faire travailler les biceps. En faisant cela, il entraine en rotation le bras d'exercice 20 et le disque 12 au travers du cliquet 13 et entraine ainsi la sortie de la tige du vérin.The user can then place his hands under the logs and bring his arms to the chest to work the biceps. By doing this, it rotates the exercise arm 20 and the disk 12 through the pawl 13 and thus causes the output of the rod of the cylinder.

On remarque que la modification de la position relative du vérin avec la longe peut être évitée dans le cas où un vérin double effet, assurant donc une résistance dans les deux sens, est utilisé.Note that the modification of the relative position of the cylinder with the lanyard can be avoided in the case where a double-acting cylinder, thus providing resistance in both directions, is used.

En particulier, la multiplicité d'exercices est encore augmentée quand on peut faire appel soit à un mouvement de sortie de la tige soit à un mouvement d'entrée de la tige dans le vérin.In particular, the multiplicity of exercises is further increased when it is possible to use either an output movement of the rod or an input movement of the rod in the jack.

Pour cela, dans une réalisation avantageuse, les vérins sont hydrauliques et la résistance se fait à l'aller et au retour de la tige. Dans ce cas, par exemple, la cheville ou le bas de la jambe de l'utilisateur est placé entre deux jeux de rondins afin de pouvoir forcer dans les deux sens. Il n'y a pas de besoin en air comprimé pour l'alimentation du vérin et cela évite de devoir apporter de l'énergie vers l'appareil selon l'invention. En plus, l'utilisateur peut s'exercer dans les deux sens du mouvement.For this, in an advantageous embodiment, the cylinders are hydraulic and the resistance is made in the forward and return of the rod. In this case, for example, the user's ankle or lower leg is placed between two sets of logs in order to be able to force in both directions. There is no need for compressed air to supply the cylinder and this avoids having to bring energy to the device according to the invention. In addition, the user can practice in both directions of the movement.

Dans une autre réalisation avec un vérin pneumatique, le vérin double effet est alimenté en air avec un système d'inversion de l'arrivée d'air pour permettre la résistance de la tige dans un sens ou dans l'autre.In another embodiment with a pneumatic cylinder, the double-acting cylinder is supplied with air with an inversion system of the air inlet to allow the resistance of the rod in one direction or the other.

Les figures 6A et 6B représente l'appareil des figures précédentes sur lequel a été ajouté un ensemble complémentaire longe/dispositif de tension/bras d'exercice à l'arrière de l'appareil, derrière l'assise ou le dossier, par exemple en lieu et place du réglage du dossier.The Figures 6A and 6B represents the apparatus of the preceding figures on which was added a complementary set lanyard / tensioning device / exercise arm at the rear of the device, behind the seat or the backrest, for example in place of the setting folder.

Cet ensemble comprend l'un ou l'autre des types de vérins ou de structure élastique.This set includes one or other of the types of cylinders or elastic structure.

Dans la réalisation présentée sur la figure 6, un tube de soutien 21 est soudé sur l'assise. Ce tube intègre un axe de rotation d'une seconde longe 3'. Cet axe de rotation est dit second axe longe 6'.In the realization presented on the figure 6 a support tube 21 is welded to the seat. This tube incorporates an axis of rotation of a second lanyard 3 '. This axis of rotation is said second axis lanyard 6 '.

La longe 3' est équipée d'un vérin 4' et d'une flasque 5' montée sur l'axe longe 6'. La flasque 5' porte 2 trous 7c et 7d servant à placer la longe 3' dans deux positions angulaires distinctes autour de l'axe longe 6'. Un cliquet 11' porté par le tube de soutien 21 bloque la longe 3' en position.The lanyard 3 'is equipped with a jack 4' and a flange 5 'mounted on the axis lanyard 6'. The flange 5 'carries 2 holes 7c and 7d for placing the lanyard 3' in two distinct angular positions around the axis lanyard 6 '. A pawl 11 'carried by the support tube 21 blocks the lanyard 3' in position.

A l'extrémité de la longe 3' est monté un nouveau bras d'exercice 20', cette fois en forme de U. Le nouveau bras d'exercice est monté en rotation par rapport à la longe 3' avec un axe 10'.At the end of the lanyard 3 'is mounted a new exercise arm 20', this time U-shaped. The new exercise arm is rotatably mounted relative to the lanyard 3 'with an axis 10'.

Une force exercée en bout du bras d'exercice 20' génère la rotation du bras d'exercice 20' qui entraine celui-ci en rotation avec l'axe 10' ce qui a pour effet d'entrainer également en rotation la biellette 9' et la tête de vérin.A force exerted at the end of the exercise arm 20 'generates the rotation of the exercise arm 20' which drives it in rotation with the axis 10 'which has the effect of also causing the rod 9' to rotate. and the cylinder head.

On peut ainsi travailler les triceps en poussant ou en tirant sur les poignées du bras d'exercice.You can work the triceps by pushing or pulling on the handles of the exercise arm.

En outre, on remarque que la réalisation de la figure 6 permet, comme pour l'ensemble longe 2/dispositif de tension 4/bras d'exercice 20, une modification de la position du bras d'exercice 20' par rapport à la longe 3' par l'intermédiaire d'un dispositif de modification du mouvement angulaire du bras d'exercice 20' comprenant un disque 12' et un cliquet 13'.In addition, we note that the realization of figure 6 allows, as for the whole lanyard 2 / tension device 4 / exercise arm 20, a modification of the position of the exercise arm 20 'with respect to the lanyard 3' by means of a modification device angular movement of the exercise arm 20 'comprising a disc 12' and a pawl 13 '.

Les figure 7A et 7B représentent l'appareil selon l'invention dans une configuration permettant un tirage haut par l'utilisateur.The Figure 7A and 7B represent the apparatus according to the invention in a configuration allowing a high draw by the user.

Pour mettre l'appareil dans cette configuration, le cliquet 11' est désolidarisé du trou 7d et un mouvement de rotation est donné à la longe 3'. Le bras d'exercice 20' est alors également entrainé en rotation par l'arrière de l'assise.To put the device in this configuration, the pawl 11 'is disengaged from the hole 7d and a rotational movement is given to the lanyard 3'. The exercise arm 20 'is then also rotated by the back of the seat.

Le cliquet 11' et le trou 7c sont alors solidarisés. La longe 3' est alors en position. Le bras d'exercice 20' est alors ensuite déplacé en position haute au niveau de l'appui tête de l'assise par actionnement du cliquet 13' et solidarisation dans un trou du disque 12'.The pawl 11 'and the hole 7c are then secured. The lanyard 3 'is then in position. The exercise arm 20 'is then moved in the up position at the headrest of the seat by actuating the pawl 13' and secured in a hole of the disc 12 '.

Alors, en poussant ou en tirant sur les poignées du bras d'exercice 20' et suivant le principe décrit précédemment on peut travailler les dorsy.Then, by pushing or pulling on the handles of the exercise arm 20 'and following the principle described above one can work the dorsy.

On remarque enfin que diverses mises en oeuvre peuvent être réalisées selon les principes de l'invention. En particulier, un système équivalent à ceux décrits peut être ajouté à l'arrière et en haut de l'appareil pour réaliser encore des exercices additionnels : pectoraux etc. Un système équivalent peut aussi être ajouté en position basse pour des exercices additionnels : adducteurs / abducteurs etc.Finally, it should be noted that various implementations can be made according to the principles of the invention. In particular, a system equivalent to those described can be added to the rear and top of the device to perform additional exercises: chest etc. An equivalent system can also be added in the lower position for additional exercises: adductor / abductor etc.

L'appareil pourra ainsi avoir un, deux ou trois systèmes à vérin mobile selon l'invention. En outre, les dispositifs de tension sont interchangeables : un vérin hydraulique pourra être remplacé par un vérin pneumatique, un vérin hydraulique pourra être remplacé par un système de sangles élastiques etc.The apparatus may thus have one, two or three mobile jack systems according to the invention. In addition, the tension devices are interchangeable: a hydraulic cylinder can be replaced by a pneumatic cylinder, a hydraulic cylinder can be replaced by a system of elastic straps etc.
