Definitions
- the present invention relates to an apparatus for global body mobilization of a human subject, that is to say an apparatus for moving the trunk, limbs and joints of the subject, and a use thereof. apparatus.
- This type of device is intended, preferably but not exclusively, to be used under the supervision of a physiotherapist who determines the mobilization movements generated by the device.
- Recent studies in neurophysiology reveal that the effectiveness of physiotherapy or osteopathy, for example on a wounded subject, an aging person or a healthy subject, or on a high-level sports practitioner, is related to the stimulation of the subject's neuro-biomechanical abilities.
- the human being receives information from different sensors, including articular, vestibular, visual, cutaneous sensors, etc.
- the brain treats this information by comparing it to internal, innate, acquired patterns, according to which the human being adjusts his bodily responses.
- these internal models are sometimes insufficiently sharpened to respond to new situations, some of these models may have been lost or never acquired through training.
- the body of the subject is not or only weakly unbalanced: during movements of the device, the support polygon the body of the subject, that is to say the virtual surface between the points of support of the feet of the subject standing on the platform and inside which must project the center of gravity of the body of the subject so that the latter is not completely unbalanced and falls, remains centered on the central support pivot.
- the sagittal axis of the body of the subject remains generally in the extension of the central support pivot, which allows only a moderate body reaction, and always of the same type.
- the weight of the subject and the efforts it produces not to fall are collected in full by the central support pin, which requires, to reduce the risk of breakage, to manufacture the latter in a particularly resistant form ; especially in the form of a universal joint.
- the driving force required to drive the platform must then be sized accordingly, which results in a particularly heavy and bulky apparatus.
- US Patent 5,813,958 also proposes an oscillating motorized platform apparatus, which, in some embodiments, incorporates a subject support tray, having a pre-fixed inclination so that the center of this tray is off-center by a fixed distance from the vertical axis around which the plateau turns.
- the imbalance of the subject is greater than with the apparatuses mentioned above, but because of the fixity of the inclination of the plate, related to the structure of the apparatus, the mobilization movements generated have a kinematic fixed and therefore inefficient and inefficient, in the sense that the subject quickly takes into account the fixed eccentricity of the plateau to quickly regain its balance and neutralize the neuro-biomechanical stimulation provided by the device by anticipating the characteristics of this stimulation .
- the structure of the apparatus proves particularly cumbersome and heavy, because of the interposition between the frame of the apparatus and its plate of a rotating disc on which the plate bears to be tilted -fixée.
- the object of the present invention is to propose a global body mobilization apparatus which, while being reliable, light and compact, allows both to unbalance the subject and to significantly shift the levitation polygon and the instantaneous pressure centers of the body of the subject, in an effective and controlled manner, in order to act on the body according to elaborate movements, able to reinforce or maintain the neuro-biomechanical skills of the subject.
- the subject of the invention is a device for global body mobilization of a human subject, as defined in claim 1.
- the center of the levitation polygon and the instantaneous pressure centers of the body of a subject may be spaced transversely from the fixed axis defined by the apparatus: when the subject stands, in particular standing, on the plateau, its support polygon is generally centered on the central zone of the plateau, while the latter is planned to be eccentric with respect to the fixed axis.
- This eccentricity of the plate is accompanied by an inclination of the latter, controlled by the peripheral support means which is provided with the plate, which causes the imbalance of the subject and the solicitation of its neuro-biomechanical capabilities, as explained below. above.
- the apparatus In use, when the plate is driven eccentrically about the fixed axis, the body of the subject is mobilized by a force centrifugal, in a circumferential direction coupled to a linear mobilization parallel to the plane of the plate, related to the inclination of the latter.
- the apparatus according to the invention produces controlled movements of its plate which unbalance the subject, causing a circumferential displacement and lateral translation of the levitation polygon and instantaneous pressure centers of the body of the subject.
- centrifugal effect of this movement applies in particular to all the body elements that make up the cylindrical beam made up of the entire trunk / abdomen.
- the reaction to this centrifugal force is a powerful effort of centripetal restoration by all the muscles of the body.
- the apparatus according to the invention thus performs a neuro-biomechanical action adapted to the articular, muscular and informational complexity of the subject's body, to render, as far as possible, all its dynamic potential or to push it within its neuro-motor limits. adjustment.
- the device generates different types of actions, such as vestibular, articular, cutaneous, postural, muscular, neurological, genito-pelvic, etc. actions.
- various areas of the body are mobilized in a coordinated manner, or even the whole body.
- the body mobilization is accompanied by a significant caloric burning.
- the body of the subject is not to be considered as a rigid and stable object: on the contrary, this body is deformable and comprises a large number of articulations which are as many degrees of freedom to control to maintain postural control and to obtain a variable and complex spatial orientation.
- the posturo-kinetic activities carried out by the subject on the device will ensure the coordination of the various articulated elements of his body: in response to the movements of the plateau, the subject sets up a postural strategy, that is to say a plan Action coordinated between the different parts of his body involved in the activity, in order to maintain or recover an efficient postural attitude.
- the weight of the subject and the mobilization efforts it generates are cashed by the peripheral support means, in other words on the periphery of the plateau, in a relatively large area where, for example, several points of support can advantageously be provided, while the corresponding bearing means are fixedly supported by the frame, without having to interpose an additional mobile component between the plate and the frame.
- the drive means are advantageously designed to produce and transmit essentially, or even exclusively, the driving forces of displacement of the plate. The necessary driving force does not have to be oversized, which results in a small size of the tray drive means.
- a device 1 of body mobilization of a subject 2 for moving the limbs and joints of the subject.
- the apparatus 1 is intended to be used under the supervision of a physiotherapist or a similar health professional, so that the latter determines the movements of mobilization imposed on the subject by the device.
- the device 1. is used in a medical office of physiotherapy or osteopathy, or more generally in a health center, for example in a retirement home or a thalassotherapy institute.
- the subject can autonomously use the apparatus 1, in particular for the purpose of physical exercises, the apparatus then being made available in a fitness room or the like.
- the apparatus 1 comprises a support frame 10 on the ground S.
- the remainder of the description is oriented relative to the ground, so that the term “vertical” designates a direction substantially perpendicular to the ground S, while the term “horizontal” designates a direction substantially perpendicular to the vertical thus defined.
- the terms “low” and “lower” denote a direction directed towards the ground, while the terms “high” and “higher” denote a direction in the opposite direction.
- the frame 10 comprises a substantially tubular structure which, seen from above as at figure 2 , has a generally hexagonal shape, with six elementary rectilinear uprights 12, which extend in the same plane. These amounts rest on the ground by means of feet 14, distributed along the periphery of the frame. At their free end, each of these feet 14 is advantageously provided with a set screw 15 ( figure 1 ), to adapt the frame 10 to any irregularities of the ground S, so that the amounts 12 extend, as far as possible, horizontally.
- Two of the uprights 12, opposed to each other, are rigidly connected by a horizontal crosspiece 16 along which is arranged a power unit 18.
- This group 18 comprises, on the one hand, an electric motor 20 whose housing external 22 is fixedly attached to the cross member 16 and, secondly, a geared motor stage 24, mounted at the output of the motor 20 and whose output shaft 26 extends vertically, in the central area of the hexagonal shape of the uprights 12. Under the control of the group 18, the shaft 26 is provided to turn on itself about its axis ZZ, as indicated by the arrow R.
- the apparatus 1 comprises means, not shown, power supply and variable motor control 20.
- the shaft 26 is secured to a horizontal straight bar 30.
- the upper end of the shaft 26 is for example fitted or screwed into a corresponding orifice of the bar 30, so that the shaft and the bar are kinematically linked to each other.
- the bar 30 also rotates about this axis, according to the rotational movement R.
- the bar 30 extends on either side of the shaft 26. At one of these longitudinal ends, the bar 30 carries an electric motor 32 whose outer housing 34 is fixed to the bar 30 and whose shaft output 36 acts on a carriage 38 slidably mounted along the bar 30.
- the motor 32 is supplied from the motor 20, via a collector 28 arranged around the shaft 26 and making it possible to make electrical connections between fixed contacts of the motor unit 18 and the rotary contacts associated with the motor 32. Electric current can thus flow, via this collector, from the motor 20 to the motor 32, including when the bar 30 rotates about the ZZ axis .
- the apparatus 1 also comprises means, not shown, for variable control of the motor 32.
- the carriage 38 is, under the control of the output shaft 36 of the motor 32, displaceable in a horizontal translational movement T, along the bar 30 which thus forms a slideway, between two extreme positions respectively represented on the figures 3 and 4 .
- Limit switch detectors are advantageously provided along the bar 30 and connected to the control means of the motor 32.
- the carriage 38 carries a straight vertical rod 40 whose lower part is fixedly secured to the carriage.
- the axis Z'-Z 'of this rod 40 thus extends parallel to the axis ZZ of the shaft 26, while being movable relative to this axis ZZ according to the horizontal translational movement T.
- the carriage 38 positions the axis Z'-Z 'away from the axis ZZ, with a horizontal spacing of eccentricity. noted e at the figure 3 .
- the carriage 38 In its extreme position of the figure 4 , the carriage 38 is disposed vertically above the shaft 26, so that the axes ZZ and Z'-Z 'extend vertically in the extension of one another.
- the eccentricity of the axis Z'-Z 'with respect to the axis ZZ is variable, according to the position of the carriage 38 along the slide bar 30, under the control of the motor 32, between a maximum value corresponding to the aforementioned distance e for the position of the carriage of the figure 3 and a zero value for the carriage position of the figure 4 .
- the rod 40 In use, when the shaft 26 rotates about itself about its axis ZZ, the rod 40 is thus rotated about this axis ZZ, being either eccentric with respect to this axis when the eccentricity of the axis Z'-Z 'is non-zero, or in the vertical extension of the shaft 26 when this eccentricity is zero. In the latter case, the rod 40 then rotates on itself, around its axis Z'-Z 'coincides with the axis Z-Z.
- the mobilization apparatus 1 further comprises a plate 44 having a global disc shape, defining a central axis of revolution 44A, as well as substantially planar upper 44B and lower face 44C.
- the plate 44 defines an orifice 46 centered on the axis 44A and whose outlet on the lower face 44C is surrounded by an annular flange 48 integral with the rest of the plate 44.
- the plate 44 is adapted to be assembled to the carriage 38, by introducing the stem 40 into the hole 46 at the bottom, with the interposition of a ball 50 shown in greater detail in FIG. figure 5 .
- This ball 50 comprises, on the one hand, an outer nut 52, immobilized in the flange 48 by a bolted cover 49, and, on the other hand, an inner nut 54 delimiting an internal bore of complementary cross section to that of the stem 40.
- the outer and inner nuts articulate one into the other, by cooperation of respective hemispherical surfaces allowing the inner nut to freely rotate in all directions relative to the outer nut, with predetermined maximum deflections. In this way, when the plate 44 is attached around the rod 40, this plate can freely pivot around the inner nut 54 of the ball 50.
- the plate 44 In its outer periphery, the plate 44 is fixedly provided with five feet 60 projecting downwards from its lower face 44C, as shown schematically in FIG. figure 6 .
- the feet 60 are intended to bear on the frame 10 when the plate is attached around the rod 40, so that the weight of the plate is, at least for the most part, or exclusively, supported by the chassis via 60, while the lower face of the ball 50 is not pressed against any of the elements located under the central zone of the plate, including the carriage 38.
- Each foot 60 extends generally in a direction parallel to the axis 44A and comprises at its lower end, a sliding pad 62 fixedly secured to the foot, for example by fitting and / or screwing.
- Each pad 62 is adapted to bear against a disc element 64 fixedly attached to the frame 10.
- five disc elements 64 are provided respectively at five of the six uprights 12 of the chassis, being distributed substantially uniformly around the periphery of these amounts.
- Each disc member 64 has a convex upper surface 64A, against which the pad 62 slidably bears, a lubricant may advantageously be applied to the surface 64A.
- This surface 64A corresponds to a portion of a fictional sphere 66 shown schematically in FIG. figure 6 .
- This sphere 66 common to all the surfaces 64A of the disc elements 64, defines a center C through which the ZZ axis passes, while each surface portion 64A extends around a central axis corresponding to a diameter of the sphere 66 and has a circular outer contour centered on this axis, as shown in FIG. figure 7 .
- the pads 62 rest in a mobile support against the surfaces 64A of the disc elements 64, as shown in FIGS. figures 3 and 4 and as shown schematically in exploded at the figure 6 .
- the pads 62 When each of the pads 62 is positioned substantially at the center 64B of the corresponding surface 64A, as shown in FIG. figure 4 and as shown schematically in dashed line at figure 7 , the plate 44 extends horizontally, being centered on the axis ZZ, as shown schematically in FIG. figure 6 .
- the assembly of the plate 44 around the rod 40 is thus conceivable only if this rod extends co-axially to the axis ZZ, with the carriage 38 in its position of the figure 4 .
- each pad 62 By sliding against the surfaces 64A, the pads 62 are freely displaceable centrally on the center C of the fictional sphere 66. The deflections of each pad are limited by the transverse extent of the surface 64A, surrounded by a projecting edge 64C.
- the plate 44 is displaceable in one piece relative to the disc elements 64, so that when one of the pads 62 occupies an extreme low position with respect to its associated surface 64A, as shown in FIG. figure 3 and as shown schematically by full train to the figure 7 , the other pads 62 occupy, against their associated surface 64A, intermediate positions between this low extreme position and an extreme high position diametrically opposed to the extreme low position relative to the center 64B of the surface 64A.
- the plate 44 is then inclined with respect to a horizontal plane, that is to say that its axis 44A forms a non-zero angle ⁇ with the vertical while its central orifice 46 is radially eccentric with respect to the axis ZZ.
- the plate 44 When the plate 44 is assembled around the rod 40, such an inclination of the plate is thus permitted only when the rod 40 is eccentric with respect to the axis ZZ, as in FIG. figure 3 .
- the radial distance between the center 64B of the surface 64A and the pad 62 in the extreme low position substantially corresponds to the value e above.
- the plate 44 occupies its horizontal configuration of the figure 4 .
- the subject 2 thus easily rises on the plate 44, with its feet resting on the upper surface 44B of this plate, as shown in FIG. figure 1 .
- the shaft 26 rotates about itself about its axis ZZ and, through the bar 30, this rotational movement is communicated to the rod 40, which turns it also on herself.
- the nut 54 then rotates freely inside the nut 52 and the plate 44 remains stationary relative to the frame 10.
- the center 44D of the plate Seen from above, following the vertical, the center 44D of the plate, defined by the intersection between the axis 44A and the face 44B, describes a circular path T44 1 centered on the axis ZZ and radius substantially e , as shown in figure 8 .
- the pads 62 slide against the surface 64A of their corresponding disc element 64 in a substantially circular trajectory centered on the center 64B of this surface, as indicated at 68 at the figure 7 .
- the body axis of the subject corresponds generally to the axis 44A, so that the vertical projection of the subject's center of gravity is instantaneously eccentric relative to the ZZ axis, being distant from the center of the supine polygon of the subject's body, while this polygon is driven in motion by the plate.
- the imbalance of the subject is more or less accentuated, forcing the latter to mobilize his body in a corresponding manner not to fall.
- the apparatus 1 is associated with a fixed railing 70, for example secured to the frame 10, that the subject can grip to avoid a total loss of balance.
- This rail 70 is schematically represented on the figure 1 only, it being understood that various forms of means allowing the subject to stand on the moving plate are conceivable.
- the control of the apparatus 1 is carried out by a physiotherapist or, more generally, a health professional, who adjusts the driving speed of the motor 20, the inclination ⁇ of the plate 44 by adjusting the position of the carriage 38 along the slide bar 30 by the motor control 32, as well as the possible actuation of the motor 32 while the motor 20 rotates, which amounts to combining the rotary movements R and horizontal translation T.
- the control means are advantageously integrated with the rail 70, so that the subject can change the drive kinematics of the plate 44 during its exercise.
- the apparatus 1 in a gym it should be noted that, in operation, all the muscles of the body of the subject are quickly and intensely stressed, which combines a significant fat burning and exercises joint relaxation and coordinated bodybuilding.
- control programs of the motors 20 and 32 may be predetermined, being stored in particular in a memory accessible to the above control means.
- the figures 10 and 11 relate to an alternative embodiment of the apparatus 1.
- This variant is distinguished from the apparatus considered Figures 1 to 9 only by its support elements of the plate 44, which replace the elements 64 envisaged so far.
- the elements 64 are replaced by five elements 84 1 to 84 5 , distributed along the periphery of the frame 10 in the same way as the elements 64.
- the element 84 3 is identical to the corresponding element 64, while the elements 84 are identical to the corresponding element 64.
- elements 84 1 , 84 2 , 84 4 and 84 5 each correspond to an element 64, but with a larger transverse size: the two elements 84 2 and 84 4 closest to the element 84 3 thus have a radial dimension, relative to their central axis, one and a half times greater than the corresponding dimension of the elements 64, while the two Elements 84 1 and 84 5 furthest away from element 84 3 have a radial dimension approximately twice as large as the corresponding dimension of elements 64.
- each of the elements 84 1 to 84 5 have a convex upper surface 84A 1 to 84A 5 , which corresponds to a portion of the fictional sphere 66 of the figure 6 and which is surrounded by a projecting peripheral edge 84C 1 to 84C 5 .
- the variant embodiment of the figures 10 and 11 further comprises an additional component, namely a guide plate 90 fixedly attached, by means of not shown connection, on any one of the elements 84 1 to 84 5 , on the element 84 3 in the example shown, covering its surface 84A 3 in the manner of a lid.
- This plate thus has a generally disc shape, dimensioned to be received in a complementary manner inside the edge 84C 3 , with its lower surface 90A complementary to the surface 84A 3 , as shown in FIG. figure 11 .
- the plate 90 delimits, according to one of its diameters, a groove 92 traversing the plate from one side to another along its thickness and thus opening on the surface 84A 3 when the plate is assembled to the element 84 3 .
- the longitudinal direction of this groove belongs to the vertical plane P84 3 containing the axis ZZ and the center 84B 3 of the element 84 3 , being noted that this plane corresponds to the plane of the figure 11 .
- the groove 92 is adapted to receive the shoe 62 of the foot 60 associated with the element 84 3 , the width of the groove being substantially equal to the corresponding dimension of the pad. The vibrations or small deflections of the plate 44 vis-à-vis the frame 10 are thus limited, giving the plateau greater stability for the subject standing on this plateau.

- the groove 92 prevents the corresponding pad 62 from describe a circular trajectory against the surface 84A 3 , similar to the trajectory 68 of the figure 7 which disrupts the overall movement of the plate 44.
- the plate 44 In operation, when the plate 44 is driven in eccentric rotation around the axis ZZ, it deviates from the position it would occupy in the absence of the plate 90, accommodating its impossibility of deflection on both sides. other of plane P84 3 at element 84 3 , by greater deflections at the level of the other elements, in particular at the elements 84 1 and 84 5 furthest away from element 84 3 .

- the amplitude of the deflections of the plate is of the order of twice that at the peripheral portion of the plate at the base of the element 84 3 , which explains the sizing of the elements 84 1 to 84 5 .
- FIG. figure 12 intermediate trajectories T44 6 and T44 7 , similar to trajectories T44 2 and T44 3 shown in FIG. figure 8 , that is, for eccentric values smaller than the value e .

- the plate 112 defines a central axis of revolution 112A and delimits, on the one hand, an upper face 112B on which the subject is intended to hold and, on the other hand, a lower face 112C directed towards the frame 110.

Abstract
Description
La présente invention concerne un appareil de mobilisation corporelle globale d'un sujet humain, c'est-à-dire un appareil permettant de mettre en mouvement le tronc, les membres et les articulations du sujet, ainsi qu'une utilisation d'un tel appareil.The present invention relates to an apparatus for global body mobilization of a human subject, that is to say an apparatus for moving the trunk, limbs and joints of the subject, and a use thereof. apparatus.
Ce genre d'appareil est destiné, préférentiellement mais non exclusivement, à être utilisé sous la supervision d'un kinésithérapeute qui détermine les mouvements de mobilisation générés par l'appareil.This type of device is intended, preferably but not exclusively, to be used under the supervision of a physiotherapist who determines the mobilization movements generated by the device.
De récentes études en neurophysiologie révèlent que l'efficacité des soins de kinésithérapie ou d'ostéopathie, pratiqués par exemple sur un sujet blessé, une personne vieillissante ou un sujet sain, ou encore sur un pratiquant de sports de haut niveau, est liée à la stimulation des capacités neuro-biomécaniques du sujet. En effet, pour se tenir debout et commander son corps, l'être humain reçoit des informations par différents capteurs, notamment des capteurs articulaires, vestibulaires, visuels, cutanés, etc. Le cerveau traite ces informations en les comparant à des modèles internes, innés et acquis, en fonction desquels l'être humain ajuste ses réponses corporelles. Cependant, ces modèles internes sont parfois insuffisamment affûtés pour répondre à des situations nouvelles, certains de ces modèles pouvant avoir été perdus ou n'avoir jamais été acquis par l'entraînement. On comprend que de la richesse de ces modèles dépend la capacité du sujet à s'adapter aux difficultés de l'environnement dans lequel il se déplace et/ou il agit. En outre, pour que les ordres de contrôle des mouvements du corps du sujet par son cerveau soient efficaces, les articulations du sujet doivent être fonctionnellement réactives et les muscles qui sous-tendent ces articulations doivent être forts et flexibles. Cependant, une partie des compétences motrices du sujet peut être perdue, notamment suite à un accident, lors de son vieillissement, lorsqu'il adopte des postures de travail inadaptées ou lorsqu'il souffre de surtension nerveuse.Recent studies in neurophysiology reveal that the effectiveness of physiotherapy or osteopathy, for example on a wounded subject, an aging person or a healthy subject, or on a high-level sports practitioner, is related to the stimulation of the subject's neuro-biomechanical abilities. In fact, to stand up and control his body, the human being receives information from different sensors, including articular, vestibular, visual, cutaneous sensors, etc. The brain treats this information by comparing it to internal, innate, acquired patterns, according to which the human being adjusts his bodily responses. However, these internal models are sometimes insufficiently sharpened to respond to new situations, some of these models may have been lost or never acquired through training. We understand that the richness of these models depends on the ability of the subject to adapt to the difficulties of the environment in which he moves and / or he acts. In addition, for the control commands of the subject's body movements through his brain to be effective, the subject's joints must be functionally responsive and the muscles underlying these joints must be strong and flexible. However, some of the subject's motor skills may be lost, particularly as a result of an accident, as he gets older, when he adopts unsuitable work postures or when he suffers from nervous surge.
On comprend ainsi que la récupération ou l'entraînement des compétences neuro-biomécaniques du sujet nécessitent des stimulations et des simulations conjointes, aussi complètes et variées que possible, de ses fonctions musculo-articulair es et de ses capacités de neuro-vigilance.It is thus understood that the recovery or training of the subject's neuro-biomechanical skills require joint stimulation and simulations, as complete and varied as possible, of his musculo-articular functions and his neurovigilance capabilities.
Les appareils permettant une telle récupération ou un tel entraînement sont aujourd'hui pratiquement inexistants. Les quelques appareils disponibles sont en général constitués d'une plateforme motorisée, qui à la fois repose et oscille sur un pivot central d'appui, comme dans
Le but de la présente invention est de proposer un appareil de mobilisation corporelle globale qui, tout en étant fiable, léger et peu encombrant, permet à la fois de déséquilibrer le sujet et de déplacer significativement le polygone de sustentation et les centres de pression instantanés du corps du sujet, de manière efficace et contrôlée, afin d'agir sur le corps suivant des mouvements élaborés, à même de renforcer ou d'entretenir les compétences neuro-biomécaniques du sujet.The object of the present invention is to propose a global body mobilization apparatus which, while being reliable, light and compact, allows both to unbalance the subject and to significantly shift the levitation polygon and the instantaneous pressure centers of the body of the subject, in an effective and controlled manner, in order to act on the body according to elaborate movements, able to reinforce or maintain the neuro-biomechanical skills of the subject.
A cet effet, l'invention a pour objet un appareil de mobilisation corporelle globale d'un sujet humain, tel que défini à la revendication 1.For this purpose, the subject of the invention is a device for global body mobilization of a human subject, as defined in
Grâce à l'appareil selon l'invention, le centre du polygone de sustentation et les centres de pression instantanés du corps d'un sujet peut être écarté transversalement de l'axe fixe défini par l'appareil : lorsque le sujet se tient, notamment debout, sur le plateau, son polygone de sustentation est globalement centré sur la zone centrale du plateau, alors que cette dernière est prévue pour pouvoir être excentrée par rapport à l'axe fixe. Cette excentration du plateau s'accompagne d'une inclinaison de ce dernier, commandée par les moyens périphériques d'appui dont est muni le plateau, ce qui provoque le déséquilibre du sujet et la sollicitation de ses capacités neuro-biomécaniques, comme expliqué ci-dessus. En service, lorsque le plateau est entraîné de manière excentrée autour de l'axe fixe, le corps du sujet est mobilisé par une force centrifuge, selon une direction circonférentielle couplée à une mobilisation linéaire parallèlement au plan du plateau, liée à l'inclinaison de ce dernier. Autrement dit, l'appareil selon l'invention produit des mouvements contrôlés de son plateau qui déséquilibrent le sujet, en provoquant un déplacement circonférentiel et en translation latérale du polygone de sustentation et des centres de pression instantanés du corps du sujet.Thanks to the apparatus according to the invention, the center of the levitation polygon and the instantaneous pressure centers of the body of a subject may be spaced transversely from the fixed axis defined by the apparatus: when the subject stands, in particular standing, on the plateau, its support polygon is generally centered on the central zone of the plateau, while the latter is planned to be eccentric with respect to the fixed axis. This eccentricity of the plate is accompanied by an inclination of the latter, controlled by the peripheral support means which is provided with the plate, which causes the imbalance of the subject and the solicitation of its neuro-biomechanical capabilities, as explained below. above. In use, when the plate is driven eccentrically about the fixed axis, the body of the subject is mobilized by a force centrifugal, in a circumferential direction coupled to a linear mobilization parallel to the plane of the plate, related to the inclination of the latter. In other words, the apparatus according to the invention produces controlled movements of its plate which unbalance the subject, causing a circumferential displacement and lateral translation of the levitation polygon and instantaneous pressure centers of the body of the subject.
L'effet centrifuge de ce déplacement s'applique en particulier sur tous les éléments corporels qui composent la poutre cylindrique constituée de l'ensemble tronc/abdomen. La réaction à cette force centrifuge est un puissant effort de restauration centripète par l'ensemble de tous les muscles du corps.The centrifugal effect of this movement applies in particular to all the body elements that make up the cylindrical beam made up of the entire trunk / abdomen. The reaction to this centrifugal force is a powerful effort of centripetal restoration by all the muscles of the body.
L'appareil selon l'invention réalise ainsi une action neuro-biomécanique adaptée à la complexité articulaire, musculaire et informationnelle du corps du sujet, pour lui rendre, autant que possible, tout son potentiel dynamique ou pour le pousser dans ses limites neuro-motrices d'ajustement. En pratique, l'appareil engendre différents types d'actions, telles que des actions vestibulaires, articulaires, cutanées, posturales, musculaires, neurologiques, génito-pelviennes, etc. En effet, selon les réglages des moyens motorisés et selon la posture du sujet sur le plateau, diverses zones du corps sont mobilisées de manière coordonnée, voire tout le corps. Lorsque le sujet se tient par exemple debout sur le plateau, on peut mobiliser ses jambes seules, ses jambes et son tronc, ou ses jambes, son tronc et ses bras. Selon le recrutement musculaire commandé, la mobilisation corporelle s'accompagne d'un brûlage calorique significatif. De manière plus générale, sur l'appareil, le corps du sujet n'est pas à considérer comme un objet rigide et stable : au contraire, ce corps est déformable et comporte un grand nombre d'articulations qui sont autant de degrés de liberté à maîtriser pour maintenir le contrôle postural et pour obtenir une orientation spatiale variable et complexe. Les activités posturo-cinétiques effectuées par le sujet sur l'appareil vont assurer la coordination des divers éléments articulés de son corps : en réponse aux mouvements du plateau, le sujet met en place une stratégie posturale, c'est-à-dire un plan d'action coordonné entre les différentes parties de son corps impliquées dans l'activité, dans le but de maintenir ou de récupérer une attitude posturale efficiente.The apparatus according to the invention thus performs a neuro-biomechanical action adapted to the articular, muscular and informational complexity of the subject's body, to render, as far as possible, all its dynamic potential or to push it within its neuro-motor limits. adjustment. In practice, the device generates different types of actions, such as vestibular, articular, cutaneous, postural, muscular, neurological, genito-pelvic, etc. actions. Indeed, according to the settings of the motorized means and according to the posture of the subject on the board, various areas of the body are mobilized in a coordinated manner, or even the whole body. When the subject stands for example standing on the board, one can mobilize his legs alone, his legs and trunk, or his legs, his trunk and his arms. According to the muscular recruitment ordered, the body mobilization is accompanied by a significant caloric burning. More generally, on the apparatus, the body of the subject is not to be considered as a rigid and stable object: on the contrary, this body is deformable and comprises a large number of articulations which are as many degrees of freedom to control to maintain postural control and to obtain a variable and complex spatial orientation. The posturo-kinetic activities carried out by the subject on the device will ensure the coordination of the various articulated elements of his body: in response to the movements of the plateau, the subject sets up a postural strategy, that is to say a plan Action coordinated between the different parts of his body involved in the activity, in order to maintain or recover an efficient postural attitude.
En outre, en service, le poids du sujet et les efforts de mobilisation qu'il génère sont encaissés par les moyens périphériques d'appui, autrement dit en périphérie du plateau, dans une zone relativement étendue où, par exemple, plusieurs points d'appui peuvent avantageusement être prévus, tandis que les moyens de portée correspondants sont portés fixement par le châssis, sans devoir interposer un composant mobile additionnel entre le plateau et le châssis. La fiabilité et la robustesses de l'appareil sont ainsi remarquables. De plus, comme la périphérie du plateau supporte les efforts les plus élevés, les moyens d'entraînement sont avantageusement prévus pour produire et transmettre essentiellement, voire exclusivement, les efforts moteurs de déplacement du plateau. La force motrice nécessaire n'a pas à être surdimensionnéé, ce qui se traduit par un faible encombrement des moyens d'entraînement du plateau.In addition, in use, the weight of the subject and the mobilization efforts it generates are cashed by the peripheral support means, in other words on the periphery of the plateau, in a relatively large area where, for example, several points of support can advantageously be provided, while the corresponding bearing means are fixedly supported by the frame, without having to interpose an additional mobile component between the plate and the frame. The reliability and robustness of the device are thus remarkable. In addition, as the periphery of the plate supports the highest forces, the drive means are advantageously designed to produce and transmit essentially, or even exclusively, the driving forces of displacement of the plate. The necessary driving force does not have to be oversized, which results in a small size of the tray drive means.

Sur les
L'appareil 1 comporte un châssis 10 d'appui sur le sol S. Par commodité, la suite de la description est orientée par rapport au sol, de sorte que le terme « vertical » désigne une direction sensiblement perpendiculaire au sol S, tandis que le terme « horizontal » désigne une direction sensiblement perpendiculaire à la verticale ainsi définie. De même, les termes « bas » et « inférieur » désignent une direction dirigée vers le sol, tandis que les termes « haut » et « supérieur » désignent une direction de sens opposé.The
Le châssis 10 comprend une structure essentiellement tubulaire qui, vue de dessus comme à la
A son extrémité libre supérieure, l'arbre 26 est solidarisé à une barre rectiligne horizontale 30. L'extrémité supérieure de l'arbre 26 est par exemple emmanchée ou vissée dans un orifice correspondant de la barre 30, de sorte que l'arbre et la barre sont liés cinématiquement l'un à l'autre. Autrement dit, lorsque l'arbre 26 tourne autour de son axe Z-Z, la barre 30 tourne également autour de cet axe, suivant le mouvement rotatif R.At its upper free end, the
La barre 30 s'étend de part et d'autre de l'arbre 26. A une de ces extrémités longitudinales, la barre 30 porte un moteur électrique 32 dont le boîtier externe 34 est fixé à la barre 30 et dont l'arbre de sortie 36 agit sur un chariot 38 monté à coulissement le long de la barre 30. Le moteur 32 est alimenté depuis le moteur 20, par l'intermédiaire d'un collecteur 28 agencé autour de l'arbre 26 et permettant de réaliser des connexions électriques entre des contacts fixes du groupe moteur 18 et des contacts rotatifs associés au moteur 32. Du courant électrique peut ainsi circuler, via ce collecteur, du moteur 20 jusqu'au moteur 32, y compris lorsque la barre 30 tourne autour de l'axe Z-Z.The
L'appareil 1 comprend également des moyens, non représentés, de commande variable du moteur 32.The
Le chariot 38 est, sous la commande de l'arbre de sortie 36 du moteur 32, déplaçable suivant un mouvement de translation horizontale T, le long de la barre 30 qui forme ainsi une glissière, entre deux positions extrêmes respectivement représentées sur les
Le chariot 38 porte une tige rectiligne verticale 40 dont la partie basse est solidarisée fixement au chariot. L'axe Z'-Z' de cette tige 40 s'étend ainsi parallèlement à l'axe Z-Z de l'arbre 26, tout en étant déplaçable par rapport à cet axe Z-Z suivant le mouvement de translation horizontale T. Dans sa position extrême de la
En service, lorsque l'arbre 26 tourne sur lui-même autour de son axe Z-Z, la tige 40 est donc entraînée en rotation autour de cet axe Z-Z, en étant soit excentrée par rapport à cet axe lorsque l'excentration de l'axe Z'-Z' est non nulle, soit dans le prolongement vertical de l'arbre 26 lorsque cette excentration est nulle. Dans ce dernier cas, la tige 40 tourne alors sur elle-même, autour de son axe Z'-Z' confondu avec l'axe Z-Z.In use, when the
L'appareil de mobilisation 1 comporte en outre un plateau 44 présentant une forme globale de disque, définissant un axe central de révolution 44A, ainsi que des faces supérieure 44B et inférieure 44C sensiblement planes.The
Dans sa partie centrale, le plateau 44 délimite un orifice 46 centré sur l'axe 44A et dont le débouché sur la face inférieure 44C est entouré par une bride annulaire 48 venue de matière avec le reste du plateau 44.In its central part, the
Le plateau 44 est adapté pour être assemblé au chariot 38, en introduisant par le bas la tige 40 dans l'orifice 46, avec interposition d'une rotule 50 représentée plus en détail à la
Dans sa périphérie extérieure, le plateau 44 est muni, de manière fixe, de cinq pieds 60 s'étendant en saillie vers le bas depuis sa face inférieure 44C, comme représenté schématiquement à la
Chaque pied 60 s'étend globalement suivant une direction parallèle à l'axe 44A et comprend, à son extrémité inférieure, un patin de glissement 62 solidarisé fixement au pied, par exemple par emmanchement et/ou vissage. Chaque patin 62 est adapté pour prendre appui contre un élément discal 64 solidarisé fixement au châssis 10. Comme représenté sur la
Chaque élément discal 64 présente une surface supérieure 64A convexe, contre laquelle le patin 62 prend appui de manière glissante, un lubrifiant pouvant avantageusement être appliqué sur la surface 64A. Cette surface 64A correspond à une portion d'une sphère fictive 66 représentée schématiquement à la
Lorsque le plateau 44 est rapporté autour de la tige 40, les patins 62 reposent en appui mobile contre les surfaces 64A des éléments discaux 64, comme représenté sur les
Par glissement contre les surfaces 64A, les patins 62 sont librement déplaçables de manière centrée sur le centre C de la sphère fictive 66. Les débattements de chaque patin sont limités par l'étendue transversale de la surface 64A, entourée par une bordure saillante 64C.By sliding against the
On comprend que le plateau 44 est déplaçable d'un seul tenant par rapport aux éléments discaux 64, de sorte que lorsque l'un des patins 62 occupe une position extrême basse vis-à-vis de sa surface associée 64A, comme représenté à la
Ainsi, lorsque le plateau 44 est assemblé autour de la tige 40, on comprend que l'entraînement du chariot 38 selon la translation horizontale T entraîne le passage du plateau 44 entre sa configuration horizontale de la
Un exemple d'utilisation de l'appareil 1 va être décrit ci-après. Initialement, on considère que le plateau 44 occupe sa configuration horizontale de la
En considérant maintenant que le moteur 20 est arrêté et que le moteur 32 est actionné, le chariot 38 est translaté horizontalement suivant le mouvement T. Le plateau 44 est alors entraîné dans un mouvement de translation correspondant. Comme ce plateau repose par ces patins 62 sur les surfaces 64A des éléments discaux 64, ce mouvement de translation provoque l'inclinaison du plateau de sorte que ce dernier forme un angle non nul α avec l'horizontale dans le plan de là
Lorsque l'inclinaison n'est pas réglée à son maximum, ce qui revient à dire que le chariot 38 est excentré avec une valeur non nulle inférieure à e, le centre 44D du plateau 44 décrit une trajectoire circulaire centrée sur l'axe Z-Z et de rayon inférieur à e. Deux exemples de telles trajectoires intermédiaires, référencées T442 et T443, sont représentés à la
Si, au cours de la rotation R commandée par le moteur 20, l'excentration entre les axes Z-Z et Z'-Z' est modifiée, par déplacement du chariot 38 le long de la barre de glissière 30, le mouvement du plateau 44 s'écarte de la cinématique de base décrite ci-dessus, pour adopter une cinématique plus élaborée, qui toutefois s'apparente instantanément à la cinématique de base. Par exemple, si le mouvement rotatif R est maintenu avec une intensité constante et s'il est combiné au mouvement translatif T, le centre 44D du plateau décrit, vu de dessus, une trajectoire T444 en forme de spirale centrée sur l'axe Z-Z, comme représenté à la
On comprend ainsi que, lorsque l'excentration entre les axes Z-Z et Z'-Z' est non nulle, comme à la
La commande de l'appareil 1 est effectuée par un kinésithérapeute ou, plus généralement, un professionnel de santé, qui règle la vitesse d'entraînement du moteur 20, l'inclinaison α du plateau 44 en réglant la position du chariot 38 le long de la barre de glissière 30 par la commande du moteur 32, ainsi que l'éventuel actionnement du moteur 32 alors que le moteur 20 tourne, ce qui revient à combiner les mouvements rotatif R et de translation horizontale T. Dans le cas où l'appareil 1 est destiné à être utilisé de manière autonome par le sujet, les moyens de commande sont avantageusement intégrés à la rambarde 70, de sorte que le sujet peut modifier la cinématique d'entraînement du plateau 44 au cours de son exercice. A ce propos, pour l'utilisation de l'appareil 1 dans une salle de fitness, on notera que, en fonctionnement, tous les muscles du corps du sujet sont rapidement et intensément sollicités, ce qui combine un brûlage significatif de graisse et des exercices d'assouplissement articulaire et de musculation coordonnée.The control of the
Dans tous les cas, des programmes de commande des moteurs 20 et 32 peuvent être prédéterminés, en étant stockés notamment dans une mémoire accessible aux moyens de commande précités.In all cases, control programs of the

Mise à part cette dimension radiale, les caractéristiques structurelles des éléments 841 à 845 sont analogues à celles des éléments 64 : chacun des éléments 841 à 845 présentent une surface supérieure 84A1 à 84A5 convexe, qui correspond à une portion de la sphère fictive 66 de la
La variante de réalisation des
En fonctionnement, lorsque le plateau 44 est entraîné en rotation excentrée autour de l'axe Z-Z, il s'écarte de la position qu'il occuperait en l'absence de la plaque 90, en accommodant son impossibilité de débattement de part et d'autre du plan P843 au niveau de l'élément 843, par des débattements plus amples au niveau des autres éléments, en particulier au niveau des éléments 841 et 845 les plus éloignés de l'élément 843. Lorsque l'excentration du plateau est maximale (valeur e), le centre 44D du plateau décrit la trajectoire T445 représentée à la
Grâce à cette variante de réalisation, l'appareil 1 fournit des cinématiques de mobilisation corporelle plus élaborées que celles fournies par l'appareil des
Avantageusement, la position angulaire de la plaque 90 est réglable par rapport à l'élément discal 843, de sorte que la position de la rainure 90 peut être modifiée de manière à faire varier la direction de la trajectoire 94 par rapport au plan P843. Dans la configuration de la rainure 92 représentée en pointillés à la
En modifiant la direction de la trajectoire 94 par rapport à l'axe Z-Z, on induit une dissymétrie des débattements du plateau 44 par rapport au plan P843, ce qui permet de solliciter de manière différenciée en intensité les côtés opposés du sujet se tenant sur le plateau.By modifying the direction of the
De manière optionnelle, l'appareil intègre des moyens non représentés permettant de faire varier la direction de la trajectoire 94 par rapport à l'axe fixe Z-Z au cours du fonctionnement de l'appareil 1, par rotation de la plaque 90 contre la surface 84A3.Optionally, the apparatus includes means not shown for varying the direction of the

Le plateau 112 définit un axe central de révolution 112A et délimite, d'une part, une face supérieure 112B sur laquelle le sujet est destiné à se tenir et, d'autre part, une face inférieure 112C dirigée vers le châssis 110. Le plateau 112 est entouré, sur sa périphérie extérieure, d'un bord 120 s'étendant vers le bas depuis la face 112C et muni, à son extrémité inférieure, d'une couronne intérieure 122 adaptée pour prendre appui sur le châssis 110. A cet effet, le châssis 110 inclut, dans sa partie haute, une paroi hémisphérique 124 s'étendant tout autour d'un plot rigide central 126 dont l'axe longitudinal W-W est sensiblement vertical. La surface inférieure 122A de la couronne 122 est sensiblement complémentaire de la surface supérieure 124A de la paroi de châssis 124, de sorte que le plateau 112 présente des capacités de déplacement vis-à-vis du châssis 110 analogues à celles du plateau 44 vis-à-vis du châssis 10 pour l'appareil 1 des
Chaque vérin 114, 116 comporte une tige 130, 132 déplaçable en translation suivant sa direction longitudinale par rapport au corps 134, 136 du vérin. L'extrémité libre de chaque tige 130, 132 est appuyée contre le plot central 126 du châssis 110, de sorte que le déploiement ou l'escamotage de la tige par rapport à son corps 134, 136 provoquent l'éloignement ou, respectivement, le rapprochement de ce corps vis-à-vis du plot 126. L'extrémité de chaque corps 134, 136. opposée à la tige correspondante 130, 132 est reliée mécaniquement au bord 120 du plateau 112, avec interposition d'une rotule 138, 140.Each

Bien entendu, le mode de réalisation des
Divers aménagements optionnels et variantes aux appareils de mobilisation 1 et 100 décrits ci-dessus sont par ailleurs envisageables. A titre d'exemples :
- pour amortir la mise en butée des patins 62 contre la bordure 64C de leur élément discal correspondant 64 lorsque le
plateau 44 est incliné avec son amplitude maximale, chaque patin 62 peut être muni d'une garniture périphérique souple, par exemple sous forme d'un anneau rapporté autour du corps principal du patin ; - d'autres formes de réalisation de l'extrémité des pieds 60 en appui mobile sur les éléments discaux 64 sont possibles, les patins 62 pouvant par exemple être remplacés par des billes ou d'autres éléments de roulement ; en particulier, les patins 62 peuvent être remplacés par des roulettes, notamment reliées de manière folle à la face inférieure du plateau ; de telles roulettes présentent l'avantage de s'adapter instantanément aux mouvements du plateau, sans effet d'inertie ou de freinage ;
- en l'absence de la
plaque 90, pour éviter des vibrations ou de petits débattements duplateau 44 vis-à-vis des éléments discaux, liés notamment aux jeux inhérents à l'appareil, des amortisseurs, de type vérin pneumatique par exemple, peuvent être prévus directement interposés entre chaque pied 60 et le châssis 10 ; - si on renonce à pouvoir faire varier l'excentration entre les axes Z-Z et Z'-Z' pendant le mouvement rotatif R généré par le groupe moteur 18, le moteur 32 peut être remplacé par tout moyen mécanique permettant de régler la position du
chariot 38 le long de labarre 30, un tel moyen étant notamment commandé manuellement, de préférence avant que le sujet ne monte sur leplateau 44 ; - les plateaux 44
et 112 peuvent présenter d'autres formes que la forme globalement discale envisagée ci-dessus ; ces plateaux peuvent ainsi présenter, vus de dessus, une forme ovoïdale, rectangulaire, etc. ; - plutôt que de prévoir que le chariot 38 est mis en butée le long de la barre de glissière 30 lorsqu'il est à l'aplomb de l'arbre 26, la barre de glissière peut être dimensionnée en longueur pour que le chariot puisse être translaté de part et d'autre de l'axe Z-Z ;
- le nombre de couples pied 60/
élément discal 64 peut être prévu supérieur ou inférieur à cinq ; de même plutôt que de prévoir des éléments distincts répartis suivant la périphérie extérieure de l'appareil, les moyens d'appui du plateau sur le châssis et/ou les moyens de portée correspondants peuvent prendre des formes de réalisation s'étendant continûment sur la périphérie de l'appareil, telles que la couronne 122 ; par exemple, les éléments discaux 64 peuvent ainsi être remplacés par une paroi annulaire centrée sur l'axe Z-Z et correspondant à la partie de la sphère 66 délimitée en pointillés à lafigure 6 ; - l'appareil peut intégrer un mécanisme opto-cinétique, fournissant un point lumineux que le sujet doit viser en le regardant ; et/ou
- au-dessus de l'appareil, une suspension de type barre ou ballon peut être prévue, pour réaliser des exercices proprioceptifs et musculaires.
- to cushion the abutment of the
pads 62 against theedge 64C of theircorresponding disc element 64 when theplate 44 is inclined with its maximum amplitude, eachpad 62 may be provided with a flexible peripheral lining, for example in the form of a ring reported around the main body of the pad; - other embodiments of the end of the
feet 60 movably resting on thedisc elements 64 are possible, thepads 62 may for example be replaced by balls or other rolling elements; in particular, thepads 62 may be replaced by rollers, in particular madly connected to the underside of the plate; such wheels have the advantage of instantly adapting to the movements of the plate, without inertia effect or braking; - in the absence of the
plate 90, to avoid vibrations or small deflections of theplate 44 vis-à-vis the disc elements, particularly related to the games inherent in the device, dampers, such as pneumatic jack, for example, can be provided directly interposed between eachleg 60 and theframe 10; - if it is not possible to vary the eccentricity between the axes ZZ and Z'-Z 'during the rotary movement R generated by the
motor unit 18, themotor 32 can be replaced by any mechanical means for adjusting the position of thecarriage 38 along thebar 30, such means being in particular manually controlled, preferably before the subject rises on theplate 44; -
44 and 112 may have other shapes than the overall disc shape envisaged above; these trays can thus have, seen from above, an ovoid, rectangular shape, etc. ;trays - rather than providing that the
carriage 38 is abutted along theslide bar 30 when it is in line with theshaft 26, the slide bar can be dimensioned in length so that the carriage can be translated on both sides of the ZZ axis; - the number of pairs of
feet 60 /disc element 64 may be greater than or less than five; likewise rather than providing separate elements distributed along the outer periphery of the apparatus, the support means of the plate on the frame and / or the corresponding bearing means can take embodiments extending continuously on the periphery of the apparatus, such as thecrown 122; for example, thedisc elements 64 can thus be replaced by an annular wall centered on the axis ZZ and corresponding to the portion of thesphere 66 delimited in dashed line at thefigure 6 ; - the device can integrate an opto-kinetic mechanism, providing a point of light that the subject must aim at looking at it; and or
- above the apparatus, a suspension of the bar or balloon type may be provided, to perform proprioceptive and muscular exercises.
