Description

APPAREIL DE MUSCULATION AVEC UNE COMPENSATION DE CHARGE  MUSCLE APPARATUS WITH CHARGE COMPENSATION
La présente invention concerne un appareil de musculation avec une compensation de charge, et un procédé de contrôle de la compensation fournie. The present invention relates to a weight training apparatus with load compensation, and a method of controlling the compensation provided.
Les appareils de musculation, de gymnastique ou de rééducation comprennent un châssis et au moins un élément destiné à être mobilisé par rapport à ce châssis par un utilisateur de l'appareil selon un mouvement d'aller et retour permettant d'exercer, successivement, des muscles ou groupes musculaires. En général, ces appareils ne permettent pas de modifier la charge, soit au cours d'un mouvement, soit entre les mouvements excentriques (une élongation contrôlée du muscle travaillé) et concentriques (un raccourcissement du muscle travaillé).  The bodybuilding, gymnastics or rehabilitation apparatus comprise a frame and at least one element intended to be mobilized with respect to this frame by a user of the apparatus in a return movement allowing to exercise successively muscles or muscle groups. In general, these devices do not make it possible to modify the load, either during a movement, or between the eccentric movements (a controlled elongation of the worked muscle) and concentric movements (a shortening of the worked muscle).
L'entraînement courant en musculation, surtout avec les appareils de musculation par rapport aux poids libres, consiste effectivement à pousser et retenir la même charge de poids. Ainsi, la résistance ne varie pas entre le mouvement excentrique et le mouvement concentrique. Les variables de l'entraînement avec les appareils classiques concernent la quantité de mouvements effectués, le nombre de séries et le nombre de répétitions de chaque série, la vitesse d'exécution, l'amplitude du mouvement, le temps de repos entre séries et la charge de chaque série, en augmentant ou diminuant la charge.  The current training in bodybuilding, especially with weight machines compared to free weights, is actually to push and retain the same weight load. Thus, the resistance does not vary between the eccentric movement and the concentric movement. The variables of the training with the conventional apparatuses concern the quantity of movements carried out, the number of series and the number of repetitions of each series, the speed of execution, the amplitude of the movement, the time of rest between series and the load each series, increasing or decreasing the load.
Cependant, des appareils de musculation ont été développés qui permettent de modifier la charge entre le mouvement excentrique et le mouvement concentrique, en général pour obtenir une charge supérieure lorsque l'utilisateur travaille en mode excentrique, car physiologiquement, les muscles ont une force plus importante en phase excentrique qu'en phase concentrique.  However, bodybuilding devices have been developed that allow to change the load between the eccentric movement and the concentric movement, usually to obtain a higher load when the user works in eccentric mode, because physiologically, the muscles have a greater force in eccentric phase than in concentric phase.
Certains entraînements appliquent ce principe afin d'optimiser le travail de l'utilisateur dans les deux modes ou pour les besoins de rééducation du muscle ou de la prévention d'une blessure, par rapport à un appareil classique où la puissance musculaire en phase excentrique est limitée par le maximum de charge possible pour l'utilisateur en phase concentrique. En général, la charge concentrique s'élève à 60% de la charge excentrique, mais ce pourcentage peut varier selon les besoins. Des moyens ont été développés pour appliquer ce principe de différence de charge aux appareils de musculation. Une façon de le faire est d'ajouter un moteur électrique qui exerce une force de traction à la charge de la pile de poids, mais une telle solution est très coûteuse et peut gêner les utilisateurs. Une autre mise en œuvre incline la pile de poids en phase concentrique qui réduit la charge et remet verticalement la pile en phase excentrique. En revanche, une telle solution est aussi coûteuse, complexe à mettre en œuvre techniquement, et pose des problèmes de sécurité et de fiabilité. Some practices apply this principle in order to optimize the user's work in both modes or for the needs of muscle rehabilitation or injury prevention, compared to a conventional device where eccentric muscle power is limited by the maximum possible load for the user in concentric phase. In general, the concentric load is 60% of the eccentric load, but this percentage may vary according to need. Means have been developed to apply this principle of difference in load to the weight machines. One way to do this is to add an electric motor that exerts a pulling force to the load of the weight stack, but such a solution is very expensive and can annoy users. Another implementation inclines the concentric phase weight stack which reduces the load and resets the cell vertically in eccentric phase. On the other hand, such a solution is also expensive, complex to implement technically, and poses problems of safety and reliability.
La figure 1 montre un appareil de musculation 1 tel que décrit par le brevet EP 2 263 759. L'appareil 1 comprend un châssis 2 comprenant des coulisseaux 3 (3-1, 3-2), une pile 4 de poids 5, un sélecteur 6 de charge de poids, et une clavette 7. Des vérins 8 (8-1, 8-2) sont fixés verticalement sur le châssis 2 de l'appareil 1. Chaque vérin 8 (8-1, 8-2) a un corps 9 (9-1, 9-2) et une tige 10 (10-1, 10-2) respectifs, la tige étant rétractée dans le corps en mode désactivé (c'est-à-dire quand la compensation des vérins n'est pas souhaitée) et en appuyant sur le sélecteur 6 en mode activé (c'est-à-dire quand la compensation des vérins est souhaitée) afin de pousser le sélecteur 6 vers le haut, fournissant une aide pour monter la charge de poids.  FIG. 1 shows a weight training device 1 as described by patent EP 2 263 759. The apparatus 1 comprises a frame 2 comprising slides 3 (3-1, 3-2), a stack 4 of weight 5, a selector 6 weight load, and a key 7. Cylinders 8 (8-1, 8-2) are fixed vertically on the frame 2 of the apparatus 1. Each cylinder 8 (8-1, 8-2) a a respective body 9 (9-1, 9-2) and shaft 10 (10-1, 10-2), the shaft being retracted into the body in deactivated mode (i.e., when the cylinder compensation is is not desired) and pressing the selector 6 in the activated mode (ie when the cylinder compensation is desired) to push the selector 6 upward, providing assistance in mounting the load of weight.
L'activation et la désactivation du fonctionnement des vérins 8 peut être accomplie à l'aide d'une commande 11 fixée sur le châssis 2, les vérins 8, un guidon 12, ou à proximité des membres non concernés par l'exercice (par exemple, si l'exercice concerne les bras, la commande 11 sera située au niveau des pieds et inversement). L'appareil comprend en outre une source d'air comprimée et une source d'énergie (non-montrées) pour faire fonctionner les vérins.  The activation and deactivation of the operation of the jacks 8 can be accomplished by means of a control 11 fixed to the frame 2, the jacks 8, a handlebar 12, or near the limbs not involved in the exercise (for example). example, if the exercise is for the arms, the control 11 will be located at the level of the feet and vice versa). The apparatus further includes a compressed air source and a power source (not shown) for operating the cylinders.
Pour utiliser l'appareil 1, l'utilisateur utilise la clavette 7 pour sélectionner un charge de poids comprenant au moins un poids 5 de la pile 4, s'assoit sur un banc 13, et attrape le guidon 12 qui est couplé aux poids 5 par une sangle et des poulies (non-montrés). L'utilisateur appuie avec son pied (ou avec la main suivant les exercices) sur la commande 11 pour activer les vérins 8 et tire le guidon 12 vers le bas en mode concentrique, avec l'aide des vérins. Une fois le mouvement vers le bas terminé, l'utilisateur relâche la commande 11 pour désactiver les vérins et laisse le guidon 12 retourner vers le haut, sous l'effet de la pesanteur, en le retenant en mode excentrique. La poussée des vérins 8 est fonction de la pression envoyée dans les vérins, qui peut être sélectionnée plus ou moins forte, ce qui permet de régler la compensation au soulèvement de la charge. Par exemple, si l'utilisateur souhaite travailler 60 kg en mode concentrique (tirer le guidon 12 vers le bas en soulevant les poids 5), il peut sélectionner 100 kg sur la pile de poids 5, et les vérins 8 fourniront une compensation équivalente à 40 kg pendant la phase concentrique, ce qui fait que l'utilisateur ressent une charge de 60 kg. To use the apparatus 1, the user uses the key 7 to select a load of weight comprising at least one weight 5 of the stack 4, sits on a bench 13, and catches the handlebar 12 which is coupled to the weights 5 by a strap and pulleys (not shown). The user presses with his foot (or with the hand following the exercises) on the control 11 to activate the cylinders 8 and pulls the handlebar 12 down in concentric mode, with the help of the jacks. Once the downward movement is completed, the user releases the control 11 to deactivate the jacks and allows the handlebar 12 to return upwards, under the effect of gravity, by retaining it in eccentric mode. The thrust of the cylinders 8 is a function of the pressure sent into the cylinders, which can be selected more or less strong, which allows to adjust the compensation to the lifting of the load. For example, if the user wishes to work 60 kg in concentric mode (pull the handlebar 12 down by lifting the weights 5), he can select 100 kg on the weight stack 5, and the cylinders 8 will provide compensation equivalent to 40 kg during the concentric phase, so that the user feels a load of 60 kg.
Une fois le travail en mode concentrique terminé et la commande 11 relâchée, les tiges 10-1, 10-2 se rétractent dans les corps 9-1, 9-2 des vérins par simple gravité, ne fournissent aucune compensation et ne gênent pas le retour du poids à la position initiale. En conséquence, l'utilisateur aperçoit une charge de 60 kg pendant la phase concentrique, et une charge de 100 kg pendant la phase excentrique.  Once the concentric work is completed and the control 11 released, the rods 10-1, 10-2 retract into the bodies 9-1, 9-2 of the cylinders by simple gravity, provide no compensation and do not interfere with the return of the weight to the initial position. As a result, the user sees a load of 60 kg during the concentric phase, and a load of 100 kg during the eccentric phase.
Par contre, il se trouve que certains utilisateurs peuvent avoir du mal à synchroniser l'appui/la relâche de la commande 11 avec les phases concentriques et excentriques. Si l'utilisateur oublie de relâcher la commande avant le début de la phase excentrique, les vérins s'opposent au mouvement de retour des tiges dans les corps, ce qui gêne la fluidité de l'exercice et peut être une source de frustration pour l'utilisateur. En outre, le fait de se concentrer sur la synchronisation des mouvements et la commande peut diminuer la concentration sur l'exercice lui-même.  On the other hand, it happens that some users may find it difficult to synchronize the support / release of the control 11 with the concentric and eccentric phases. If the user forgets to release the control before the start of the eccentric phase, the cylinders are opposed to the movement of the rods back into the body, which hampers the fluidity of the exercise and can be a source of frustration for the user. 'user. In addition, focusing on synchronization of movements and control may decrease focus on the exercise itself.
Il est souhaité de trouver une solution pour pallier ces inconvénients. It is desired to find a solution to overcome these disadvantages.

Embodiments of a system and a method according to the invention will be set forth in the following description, given as a non-limitative example, with reference to the appended figures in which:
- La figure 1, précédemment décrite, représente un appareil de musculation de l'art antérieur équipé d'une compensation de la charge ;  - Figure 1, previously described, shows a weight training apparatus of the prior art equipped with a load compensation;
- La figure 2 représente une vue en perspective d'un système de détection de mouvement d'une charge et de contrôle de compensation de la charge selon un mode de réalisation ; et  FIG. 2 is a perspective view of a load motion detection and charge compensation control system according to one embodiment; and
- La figure 3 représente une vue de dessus du système de la figure 2.  FIG. 3 represents a view from above of the system of FIG. 2.
Les figures 2 et 3 représentent une vue en perspective et une vue de dessus d'un système de détection de mouvement 15 d'une charge et de contrôle de compensation de la charge, le système étant destinée à équiper un appareil conventionnel comme décrit en relation avec la figure 1. Par rapport à l'appareil montré en relation avec la figure 1, les mêmes éléments ont conservé les mêmes références.  Figures 2 and 3 show a perspective view and a top view of a load sensing and load compensation control system, the system being for equipping a conventional apparatus as described in relation to with Figure 1. Compared with the apparatus shown in relation to Figure 1, the same elements have retained the same references.
Le système de détection et de contrôle 15 comprend un module électrique vertical 16 avec une pluralité de récepteurs 17 et un émetteur 18 agencé sur la clavette 7. L'émetteur 18 peut être agencé dans la poignée de la clavette 7, avec le module 16 agencé devant la pile de poids 4, ou au contraire, l'émetteur 18 peut être agencé à l'extrémité de la clavette 7, avec le module 16 agencé derrière la pile de poids 4. La solution retenue dépend de l'appareil, des préférences du fabricant, etc. Ici, la première solution est montrée.  The detection and control system 15 comprises a vertical electrical module 16 with a plurality of receivers 17 and a transmitter 18 arranged on the key 7. The transmitter 18 can be arranged in the handle of the key 7, with the module 16 arranged in front of the weight stack 4, or on the contrary, the transmitter 18 can be arranged at the end of the key 7, with the module 16 arranged behind the stack of weight 4. The solution chosen depends on the device, preferences from the manufacturer, etc. Here, the first solution is shown.
Chaque poids 5 comprend un trou traversant 19 qui débouche sur sa face supérieure et sur sa face inférieure afin de permettre à une tige de sélecteur 20 d'être introduite verticalement dans la pile 4 des poids 5. Chaque poids 5 comprend en outre un trou 21 sur sa face avant pour recevoir la clavette 7 horizontalement dans une cavité 22 (montrée à la figure 3). Le trou traversant 19 et la cavité 22 se croisent, permettant à l'extrémité de la clavette d'être insérée dans un trou de réception 23 de la tige 20 afin de sélectionner la charge (le poids et les poids au-dessus, le cas échéant), et ainsi de sélectionner le nombre désiré de poids 5 qui seront travaillés.  Each weight 5 comprises a through hole 19 which opens on its upper face and on its underside to allow a selector rod 20 to be introduced vertically into the stack 4 of the weights 5. Each weight 5 further comprises a hole 21 on its front face to receive the key 7 horizontally in a cavity 22 (shown in Figure 3). The through-hole 19 and the recess 22 intersect, allowing the end of the key to be inserted into a receiving hole 23 of the stem 20 to select the load (the weight and the weights above, the case appropriate), and so select the desired number of weights 5 that will be worked.
Les récepteurs 17 sont fixés et raccordés électriquement sur le module 16 qui est agencé longitudinalement devant la face avant de la pile 4, à côté de la clavette 7 afin que le déplacement de la clavette avec la montée et la descente des poids longe le chemin des récepteurs 17 du module 16. L'émetteur 18 est ici un aimant et les récepteurs 17 sont des contacts ouverts/fermés disposés dans le champ magnétique de l'émetteur 18, permettant d'assurer la détection par un ou plusieurs récepteurs 17 de la proximité de l'émetteur 18 pendant son déplacement. The receivers 17 are fixed and electrically connected to the module 16 which is arranged longitudinally in front of the front face of the battery 4, next to the key 7 so that the movement of the key with the rise and the descent of the weights goes along the path of the receivers 17 of the module 16. The transmitter 18 is here a magnet and the receivers 17 are open / closed contacts arranged in the magnetic field of the transmitter 18, making it possible to ensure the detection by one or more receivers 17 of the proximity of the transmitter 18 during his displacement.
Plus spécifiquement, les récepteurs 17 peuvent être des interrupteurs à lames souples (ou « interrupteurs reed ») comprenant deux contacts magnétisables et élastiques qui s'aimantent en présence d'un champ magnétique. Les contacts sont attirés l'un par l'autre, se rapprochent et se touchent, établissant un courant. Une fois que le champ magnétique n'est plus présent, l'aimantation cesse et les contacts ne sont plus attirés et se séparent, coupant le courant. Chaque interrupteur est relié à un circuit de détection par un circuit électronique spécifique afin que son état, ouvert ou fermé, puisse être discerné individuellement.  More specifically, the receivers 17 may be soft reed switches comprising two magnetizable and elastic contacts that magnetize in the presence of a magnetic field. The contacts are attracted to each other, come closer and touch each other, establishing a current. Once the magnetic field is no longer present, the magnetization stops and the contacts are no longer attracted and separate, cutting off the current. Each switch is connected to a detection circuit by a specific electronic circuit so that its state, open or closed, can be discerned individually.
En conséquence, le déplacement de la clavette 7 selon l'axe Z fait en sorte que le champ magnétique de l'émetteur 18 provoque la fermeture, et ensuite la réouverture, des contacts progressivement. Ces changements d'état sont détectés par le circuit de détection qui permet de détecter le mouvement de la clavette, et par inférence le poids sélectionné et le mouvement du poids.  Consequently, the movement of the key 7 along the Z axis causes the magnetic field of the emitter 18 to cause the contacts to close and then reopen gradually. These changes of state are detected by the detection circuit which makes it possible to detect the movement of the key, and by inference the selected weight and the movement of the weight.
Le nombre total de récepteurs 17, ainsi que la distance entre chaque récepteur, dépend de la précision souhaitée et de la longueur totale du chemin maximum parcouru par la clavette. Plusieurs récepteurs peuvent être « actionnés » à la fois, selon la distance entre eux, la vitesse de mouvement, etc.  The total number of receivers 17, as well as the distance between each receiver, depends on the desired accuracy and the total length of the maximum path traveled by the key. Several receivers can be "operated" at a time, depending on the distance between them, the speed of movement, etc.
Il est à noter que la technologie de détection de mouvement décrite dans l'exemple n'est pas limitative. Toute technologie (mécanique, optique par moyen d'un laser installé sur la clavette et des capteurs optiques installés sur le module, etc., inductive) utilisant le principe décrit ici, où la clavette mobile est émettrice et le récepteur est fixe et constitué d'un ensemble de détecteurs, est inclue dans la présente invention.  It should be noted that the motion detection technology described in the example is not limiting. Any technology (mechanical, optical by means of a laser installed on the key and optical sensors installed on the module, etc., inductive) using the principle described here, where the mobile key is emitting and the receiver is fixed and consists of a set of detectors is included in the present invention.
Par ailleurs, l'inverse est également possible, c'est-à-dire un récepteur sur la clavette et un ou plusieurs émetteurs fixes est aussi possible, de même qu'un émetteur mobile et un ou plusieurs récepteur(s) mobile(s), mais peut être plus cher et/ou plus difficile à mettre en œuvre. On pourrait en outre installer un système de détection et de contrôle par rapport à la tige de sélecteur 20, par exemple un moyen agencé par rapport à chaque trou de réception 23 pour détecter l'insertion de l'extrémité de la clavette 7 pour en déduire le poids. Ensuite, un moyen pour détecter le déplacement de la clavette 7, par exemple un moyen de compter le nombre de rotations d'une poulie, permettrait de déterminer le déplacement des poids. Moreover, the opposite is also possible, that is to say a receiver on the key and one or more fixed transmitters is also possible, as well as a mobile transmitter and one or more mobile receiver (s) ), but may be more expensive and / or more difficult to implement. In addition, it would be possible to install a detection and control system with respect to the selector rod 20, for example a means arranged with respect to each receiving hole 23 to detect the insertion of the end of the key 7 so as to deduct the weight. Then, a means for detecting the movement of the key 7, for example a means of counting the number of rotations of a pulley, would make it possible to determine the displacement of the weights.
Le module 16 est connecté à une alimentation électrique, et peut être connecté à un convertisseur numérique/analogique qui rend le module compatible avec tout autre système de détection et de contrôle, notamment à une imprimante papier, à un ordinateur, un écran tactile, etc.  The module 16 is connected to a power supply, and can be connected to a digital-to-analog converter that makes the module compatible with any other detection and control system, including a paper printer, a computer, a touch screen, etc. .
L'appareil selon un mode de réalisation permet à l'utilisateur de choisir un mode d'entraînement particulier, selon ses besoins et objectifs. Pour cela, l'appareil peut être équipé de plusieurs boutons poussoirs sur sa face avant, ou un écran par exemple.  The apparatus according to one embodiment allows the user to choose a particular training mode, according to his needs and objectives. For this, the device can be equipped with several push buttons on its front panel, or a screen for example.
En outre, l'appareil offre une sécurité en ce que la compensation de charge fournie ne peut pas être supérieure à la charge sélectionnée par l'utilisation car il détecte la charge sélectionnée. En conséquence, la charge ne peut pas se déplacer sous la seule action des vérins, ce qui présente un risque pour l'utilisateur et peut diminuer le fonctionnement de l'appareil.  In addition, the apparatus provides security in that the charge compensation provided can not be greater than the charge selected by the use because it detects the selected charge. As a result, the load can not move under the action of the cylinders, which presents a risk for the user and can reduce the operation of the device.
Mode concentrique/excentrique standard Standard concentric / eccentric mode
Dans ce mode de réalisation, l'utilisateur choisit un poids pour la phase excentrique ou un poids pour la phase concentrique, et le système détermine le poids pour l'autre phase, en fonction du pourcentage applicable, par exemple 40% comme décrit plus haut. Ce pourcentage peut être fixe, variable grâce à un écran tactile, ou avec plusieurs boutons poussoirs correspondants (30%, 40% et 50% seulement, par exemple). Il est possible qu'un entraîneur détermine les poids à utiliser, dans ce cas, un mot de passe peut être requis.  In this embodiment, the user selects a weight for the eccentric phase or a weight for the concentric phase, and the system determines the weight for the other phase, depending on the applicable percentage, for example 40% as described above. . This percentage can be fixed, variable thanks to a touch screen, or with several corresponding pushbuttons (30%, 40% and 50% only, for example). It is possible for a trainer to determine the weights to use, in which case a password may be required.
L'appareil applique l'assistance choisie dès que le mouvement est détecté grâce au système pour la phase concentrique. Une fois que le système détecte que le poids change de direction, les vérins sont désactivés.  The device applies the selected assistance as soon as the movement is detected by the system for the concentric phase. Once the system detects that the weight changes direction, the jacks are disabled.
Mode Vibration Vibration mode
Dans ce mode d'utilisation, la charge est continuellement variée, ce qui force l'utilisateur à ajuster sa force et à compenser en permanence. La compensation offerte par les vérins est alors modifiée en cours de mouvement, soit selon un programme déterminé, soit aléatoirement. Dans ce cas, la détection du déplacement de la charge est utilisée pour contrôler la compensation offerte par les vérins. Mode Assistance au Démarrage In this mode of use, the load is continuously varied, forcing the user to adjust his strength and continuously compensate. The compensation offered by the cylinders is then modified during movement, either according to a specific program, or randomly. In this case, load displacement detection is used to control the compensation offered by the jacks. Startup Assistance Mode
Dans ce mode d'utilisation, la compensation offerte par les vérins varie, elle est généralement plus importante en début de mouvement, et moins importante en fin de mouvement. Ce mode d'utilisation peut être avantageux pour les exercices où l'utilisateur a plus de mal à démarrer le mouvement, par exemple pour des raisons ergonomiques. La compensation fournie peut être par exemple de 70% pendant le premier quart de mouvement, et une fois que le système détecte que le mouvement a dépassé un quart, la compensation est réduite à 40%.  In this mode of use, the compensation offered by the cylinders varies, it is generally more important at the beginning of movement, and less important at the end of the movement. This mode of use can be advantageous for exercises where the user has more trouble starting the movement, for example for ergonomic reasons. The compensation provided may be, for example, 70% during the first quarter of movement, and once the system detects that the movement has exceeded a quarter, the compensation is reduced to 40%.
Mode Stato- Dynamique Statodynamic mode
Dans ce mode d'utilisation, la compensation offerte par les vérins varie, de sorte qu'elle est importante sur une partie du mouvement et nulle ou presque nulle sur l'autre partie du mouvement. Ce mode d'utilisation permet de déplacer la charge sans beaucoup d'effort sur une partie du mouvement, de s'immobiliser et retenir toute la charge en statique pendant un moment, puis de pousser la charge en accélérant en sollicitant la compensation.  In this mode of use, the compensation offered by the cylinders varies, so that it is important on one part of the movement and zero or almost zero on the other part of the movement. This mode of use makes it possible to move the load without much effort on a part of the movement, to stop and to retain all the charge statically for a moment, then to push the load by accelerating by soliciting the compensation.
Mode assistance Support mode
Dans ce mode d'utilisation, l'appareil peut détecter que l'amplitude du mouvement se réduit, et peut en déduire que l'utilisateur se fatigue. Dans ce cas, le système fournit une compensation (par exemple 10 à 20 % de la charge) pour alléger la charge et permettre l'utilisateur de finir la série.  In this mode of use, the device can detect that the amplitude of the movement is reduced, and can deduce that the user is tired. In this case, the system provides compensation (for example 10 to 20% of the load) to lighten the load and allow the user to finish the series.
Il sera compris par l'Homme du Métier que l'invention décrite peut être mise en œuvre différemment, avec des différentes façons de détecter le mouvement de la charge, de traiter les informations, de contrôler les vérins, de modifier et de contrôler la compensation, etc. Le nombre de vérins n'est pas limité à deux, mais peut être plus ou moins selon leurs capacités et les besoins de l'appareil. It will be understood by those skilled in the art that the described invention can be implemented differently, with different ways of detecting the movement of the load, processing the information, controlling the jacks, modifying and controlling the compensation. etc. The number of jacks is not limited to two, but can be more or less depending on their capabilities and the needs of the device.
Il n'est pas nécessaire qu'une pluralité de poids puisse être sélectionnée. Il est possible qu'une seule charge soit utilisée. Par exemple, l'appareil peut comporter une charge non-modifiable ou « monobloc » de 100 kg. Afin de choisir la charge à travailler, l'utilisateur indique le poids de travail sur un écran et le système fournit une compensation permanente de sorte que la charge résiduelle corresponde à la valeur choisie. It is not necessary that a plurality of weights can be selected. It is possible that only one load is used. For example, the apparatus may comprise a non-modifiable load or "monoblock" of 100 kg. In order to choose the load to work, the user indicates the weight of work on a screen and the system provides permanent compensation so that the residual charge matches the chosen value.
En outre, il n'est pas non plus nécessaire de détecter la valeur de la charge sélectionnée, mais simplement le mouvement de la charge, afin de contrôler (activer, désactiver, augmenter, diminuer, varier, etc.) automatiquement la compensation fournie par les vérins.  In addition, it is also not necessary to detect the value of the selected load, but simply the movement of the load, in order to control (activate, deactivate, increase, decrease, vary, etc.) automatically the compensation provided by the cylinders.
Dans un mode de réalisation, l'appareil de musculation comprend un micro-ordinateur comprenant une mémoire qui stocke un code configuré pour exécuter les différents modes d'utilisation, avec la détection du mouvement et la fourniture de la compensation de charge en fonction de la mode d'utilisation choisie et la détection du mouvement. Ce code peut être stocké sur un support non transitoire.  In one embodiment, the weight training apparatus comprises a microcomputer comprising a memory that stores a code configured to execute the different modes of use, with the motion detection and the provision of the charge compensation as a function of the chosen mode of use and motion detection. This code can be stored on a non-transitory medium.
