Abstract

The apparatus has a vertical post (1) and a bearing which supports the foot rests (8) moves axially along it. The bearing is joined to the base of the post by a cord (10) which has a spring (6) or an elastically deformable part. When the foot rests are pushed down this returns them to their high position. The upper position of the bearing is limited by a cursor (5) whose position can be adjusted. Near the upper end of the post there is a pulley (9), turning round a horizontal axle, and the cord passes round this.

Description

Appareil de mobilisation du membre inférieur.Mobilization device of the lower limb.

La présente invention concerne un appareil de mobilisation du membre inférieur.The present invention relates to an apparatus for mobilizing the lower limb.

Cet appareil tend à mettre en mouvement les articulations, en particulier celles du genou et de la hanche, pour rétablir leur souplesse. Cet appareil s'adresse également aux sportifs qui désirent faire travailler des muscles et des articulations des membres inférieurs.This device tends to set in motion the joints, in particular those of the knee and the hip, to restore their flexibility. This device is also intended for athletes who want to work the muscles and joints of the lower limbs.

Les appareils de gymnastique ou de rééducation connus à ce jour sont constitués d'un bâti équipé de pédales oscillantes sur lesquelles l'utilisateur appuie alternativement de manière à exercer ses muscles ou ses articulations. De tels dispositifs sont complexes et ne permettent pas la rééducation d'un seul membre. En outre, ils ne permettent pas de travailler soit en mouvement dit en actif aidé, soit en mouvement dit en actif. Enfin, ils limitent l'amplitude du mouvement qui peut être réalisé.Gymnastics or rehabilitation equipment known to date consist of a frame equipped with oscillating pedals on which the user presses alternately so as to exercise his muscles or his joints. Such devices are complex and do not allow the rehabilitation of a single member. In addition, they do not allow you to work either in movement called active assisted, or in movement called active. Finally, they limit the amplitude of the movement that can be achieved.

Dans le cas d'une utilisation du dispositif correspondant à un mouvement dit en actif aidé, on travaille surtout le relèvement du membre inférieur. A l'inverse, dans le cas d'une position d'utilisation correspondant à un mouvement dit en actif, on travaille surtout l'effort de poussée du membre par rapport à un appui quelconque.In the case of using the device corresponding to a movement known as assisted active, we mainly work on raising the lower limb. Conversely, in the case of a position of use corresponding to a so-called active movement, the thrust effort of the member is mainly worked with respect to any support.

Le but de la présente invention est donc de pallier les inconvénients précités en proposant un dispositif de mobilisation du membre inférieur pour la rééducation ou l'entretien physique susceptible de permettre de travailler indifféremment dans une position d'utilisation correspondant à un mouvement dit en actif aidé ou dans une position d'utilisation correspondant à un mouvement dit en actif.The object of the present invention is therefore to overcome the aforementioned drawbacks by proposing a device for mobilizing the lower limb for rehabilitation or physical maintenance capable of making it possible to work indifferently in a position of use corresponding to a movement known as assisted active or in a position of use corresponding to a movement called active.

L'invention concerne à cet effet un appareil de mobilisation du membre inférieur, caractérisé en ce qu'il comporte un support vertical formant mât, un palier support de repose-pieds mobile axialement le long dudit mât, ce palier étant relié à au moins un point fixe dudit mât par l'intermédiaire d'au moins un lien comportant au moins une portion élastiquement déformable de manière à ce que l'ensemble palier/repose-pieds puisse, sous l'effet d'une action de poussée exercée par le membre sur le repose-pied, s'abaisser, contre l'action du lien élastiquement déformable, qui tend à rappeler ledit palier dans une position haute.To this end, the invention relates to a device for mobilizing the lower limb, characterized in that it comprises a vertical support forming a mast, a footrest support bearing movable axially along said mast, this bearing being connected to at least one fixed point of said mast by means of at least one link comprising at least one elastically deformable portion so that the bearing / footrest assembly can, under the effect of a pushing action exerted by the member on the footrest, lower, against the action of the elastically deformable link, which tends to recall said bearing in a high position.

Selon une forme de réalisation préférée de l'invention, au moins l'une des positions extrêmes du palier est limitée au moyen d'un organe, tel qu'un curseur, mobile le long dudit mât.According to a preferred embodiment of the invention, at least one of the extreme positions of the bearing is limited by means of a member, such as a slider, movable along said mast.

Le dispositif de mobilisation du membre inférieur, objet de l'invention, est constitué d'au moins un support vertical 1 formant mât et d'un palier 2 mobile le long dudit mât 1. Ce palier 2 est équipé de repose-pieds 8 disposés généralement en regard, comme le montre la figure 1. Ces repose-pieds 8 peuvent être montés à orientation réglable sur ledit mât pour assurer à l'utilisateur une position d'appui optimale.The device for mobilizing the lower limb, object of the invention, consists of at least one vertical support 1 forming a mast and a bearing 2 movable along said mast 1. This bearing 2 is equipped with footrests 8 arranged generally facing, as shown in Figure 1. These footrests 8 can be mounted with adjustable orientation on said mast to ensure the user an optimal support position.

Le palier 2 est relié, par l'intermédiaire d'au moins un lien flexible 10 au moins partiellement élastique au mât 1, de manière à pouvoir, sous l'effet d'une action de poussée exercée par le membre sur le repose-pieds 8, s'abaisser contre l'action du lien 10 élastiquement déformable qui tend à rappeler ledit palier 2 dans une position haute.The bearing 2 is connected, via at least one flexible link 10 at least partially elastic to the mast 1, so as to be able, under the effect of a pushing action exerted by the member on the footrest 8, lower against the action of the elastically deformable link 10 which tends to return said bearing 2 to a high position.

Ce lien flexible, peut affecter un grand nombre de formes.This flexible link can affect a large number of forms.

Il comprend une partie flexible, constituée par exemple par un câble, une chaîne ou une courroie et une partie élastiquement déformable 6 constituée par un tendeur ou un ressort. Grâce à cette liaison établie entre le palier 2 et le mât 1 par l'intermédiaire du lien flexible 10, le palier 2 se déplace le long du mât 1 entre deux positions extrêmes haute et basse. La position basse est généralement limitée par l'embase 3 du mât 1, tandis que la position haute est limitée au moyen d'un organe 5, tel qu'un curseur, mobile le long dudit mât 1 et susceptible d'être immobilisé dans une position déterminée. De ce fait, il est possible de faire varier l'amplitude du mouvement réalisé par l'utilisateur.It comprises a flexible part, constituted for example by a cable, a chain or a belt and an elastically deformable part 6 constituted by a tensioner or a spring. Thanks to this connection established between the bearing 2 and the mast 1 via the flexible link 10, the bearing 2 moves along the mast 1 between two extreme high and low positions. The low position is generally limited by the base 3 of the mast 1, while the high position is limited by means of a member 5, such as a slider, movable along said mast 1 and capable of being immobilized in a determined position. Therefore, it is possible to vary the amplitude of the movement performed by the user.

Il peut être également intéressant, pour pouvoir permettre à l'utilisateur de travailler soit dans une position correspondant à un mouvement dit en actif, soit dans une position correspondant à un mouvement dit en actif aidé, de faire varier la force nécessaire pour obtenir une tension dudit lien. En effet, dans le cas où le poids du membre est supérieur à la force nécessaire à la tension du lien, le mouvement est dit en actif aidé. A l'inverse, dans le cas où la force nécessaire à la tension du lien est supérieure ou égale au poids du membre, le mouvement est dit en actif.It may also be advantageous, to be able to allow the user to work either in a position corresponding to a so-called active movement, or in a position corresponding to a so-called assisted movement, to vary the force necessary to obtain a tension said link. Indeed, in the case where the weight of the limb is greater than the force necessary for the tension of the link, the movement is said to be an active asset. Conversely, in the case where the force necessary for the tension of the link is greater than or equal to the weight of the member, the movement is said to be active.

Pour modifier l'effort nécessaire à la tension du lien 10, plusieurs modes de réalisation, dont deux exemples sont représentés aux figures 3 et 4, peuvent être envisagés.To modify the force necessary for the tension of the link 10, several embodiments, two examples of which are shown in FIGS. 3 and 4, can be envisaged.

Dans ce cas, le mât 1 est équipé au voisinage de son extrémité supérieure d'au moins une poulie 9 constituant un organe de transmission, cette poulie étant montée libre à rotation sur un axe 11 sensiblement horizontal logé à l'intérieur d'un palier supplémentaire 4 introduit par exemple par coulissement ou emmanché à force à l'extrémité supérieure du mât 1. Le lien flexible 10 disposé partiellement dans le mât 1 est guidé dans la gorge de ladite poulie 9 pour être raccordé au palier 2 support de repose-pieds 8. Ce lien flexible comporte une portion élastiquement déformable 6 constituée par un tendeur, ce tendeur étant équipé à son extrémité libre d'un mousqueton 12 qui permet la fixation dudit tendeur sur le palier 2 mobile support de repose-pieds 8. L'autre extrémité du lien flexible est fixée en un point fixe quelconque 13 à l'intérieur du mât.Au cours du mouvement de monte et baisse du palier 2 support des repose-pieds 8 commandé par le mouvement du membre inférieur de l'utilisateur, le lien flexible 10 et sa portion élastiquement déformable 6 se déplacent dans la gorge de la poulie 9 en entraînant, sous l'effet de poussée du palier 2, une tension du tendeur 6.
Lorsque l'on veut augmenter cette force nécessaire à la tension du tendeur 6, il suffit d'équiper le dispositif d'au moins deux poulies 9 montées sur un même axe porteur 11, chaque poulie recevant un lien flexible équipé d'un tendeur 6, chaque tendeur 6 étant solidarisé au moyen du mousqueton 12 au palier 2. Dans l'exemple représenté à la figure 3, le dispositif est équipé de trois poulies. Bien évidemment, le nombre de poulies est quelconque. De même, les tendeurs 6 peuvent être identiques ou différents.In this case, the mast 1 is equipped in the vicinity of its upper end with at least one pulley 9 constituting a transmission member, this pulley being mounted free to rotate on a substantially horizontal axis 11 housed inside a bearing additional 4 introduced for example by sliding or force-fitted at the upper end of the mast 1. The flexible link 10 disposed partially in the mast 1 is guided in the groove of said pulley 9 to be connected to the bearing 2 footrest support 8. This flexible link comprises an elastically deformable portion 6 constituted by a tensioner, this tensioner being equipped at its free end with a carabiner 12 which allows the fixing of said tensioner on the bearing 2 movable footrest support 8. The other end of the flexible link is fixed at any fixed point 13 inside the mast. During the upward and downward movement of the bearing 2 footrest support 8 controlled by the movement ment of the lower limb of the user, the flexible link 10 and its elastically deformable portion 6 move in the groove of the pulley 9 causing, under the pushing effect of the bearing 2, a tension of the tensioner 6.
When it is desired to increase this force necessary for tensioning the tensioner 6, it suffices to equip the device with at least two pulleys 9 mounted on the same load-bearing axle 11, each pulley receiving a flexible link equipped with a tensioner 6 , each tensioner 6 being secured by means of the carabiner 12 to the bearing 2. In the example shown in Figure 3, the device is equipped with three pulleys. Obviously, the number of pulleys is arbitrary. Similarly, the tensioners 6 can be identical or different.

Dans l'exemple représenté à la figure 4, le dispositif comporte, en tête de mât 1, un bloc de poulies formé d'au moins deux groupes de jantes montées libres à rotation sur un axe 11 commun, chaque groupe comportant une première jante 9a et une seconde jante 9b de diamètre différent ou identique, solidaire en rotation, guidant respectivement un lien enroulable l0a, lOb. Le lien l0a de la première jante 9a, comprenant une portion élastiquement déformable 6, est raccordé entre la première jante 9a et un point fixe du mât 1 tandis que le lien de la seconde jante 9b est raccordé entre cette seconde jante et le palier 2 support de reposepieds 8.In the example shown in FIG. 4, the device comprises, at the top of the mast 1, a block of pulleys formed by at least two groups of rims mounted free to rotate on a common axis 11, each group comprising a first rim 9a and a second rim 9b of different or identical diameter, integral in rotation, respectively guiding a windable link l0a, lOb. The link 10a of the first rim 9a, comprising an elastically deformable portion 6, is connected between the first rim 9a and a fixed point of the mast 1 while the link of the second rim 9b is connected between this second rim and the bearing 2 support footrest 8.

Le fonctionnement d'un tel dispositif est le suivant : lors d'un effort de poussée exercé sur le repose-pieds 8, le lien flexible lOb enroulé sur la deuxième jante 9b se déroule tandis que le lien flexible l0a disposé sur la première jante 9a s enroule. A l'inverse, lors de la remontée dudit palier 2 support de repose-pieds 8, le lien flexible lOb enroulé sur la deuxième jante 9b s'enroule tandis que le lien flexible l0a enroulé sur la première jante 9a se déroule.The operation of such a device is as follows: during a pushing force exerted on the footrest 8, the flexible link lOb wound on the second rim 9b takes place while the flexible link l0a disposed on the first rim 9a rolls up. Conversely, during the ascent of said bearing 2 footrest support 8, the flexible link lOb wound on the second rim 9b is wound while the flexible link l0a wound on the first rim 9a takes place.

Le lien flexible lOb de la seconde jante 9b de chaque poulie peut être, en position d'utilisation du dispositif, désolidarisé ou solidarisé du palier 2 support de reposepieds 8 de manière à modifier l'effort nécessaire pour assurer la descente du palier 2 support de repose-pieds 8 le long du mât 1. De même, le choix des diamètres de jantes 9a, 9b permet de modifier l'effort nécessaire à la descente du palier 2. Enfin, cet appareil de mobilisation peut être équipé d'un dispositif d'arrêt du palier 2 dans une position quelconque lorsque le pied glisse du repose-pieds 8.The flexible link lOb of the second rim 9b of each pulley can be, in the position of use of the device, disconnected or secured to the bearing 2 footrest support 8 so as to modify the force necessary to ensure the descent of the bearing 2 support footrest 8 along the mast 1. Likewise, the choice of rim diameters 9a, 9b makes it possible to modify the force required to descend the bearing 2. Finally, this mobilization device can be equipped with a device for '' stop of the bearing 2 in any position when the foot slides from the footrest 8.

Cet appareil de mobilisation peut être fixé à demeure ou peut se présenter sous forme d'un dispositif autonome, installable en un endroit quelconque. Dans ce cas, le mât 1 est équipé, au niveau de son embase 3 et de son extrémité supérieure, de moyens de fixation et/ou de guidage du dispositif sur un support quelconque tel qu'un chant de porte. L'embase peut, à titre d'exemple, être constituée par un tripode, au moins deux des branches du tripode étant équipées de plaques de serrage qui peuvent venir enserrer le chant de la porte. Cette embase est dans ce cas éventuellement pourvue d'un système anti-dérapant formé par exemple par des patins. La tête de mât peut quant à elle être équipée d'un ou plusieurs crochets 14 représentés à la figure 2 qui permettent la fixation de l'appareil sur une poignée de porte. En outre, pour parfaire l'appareil, ce dernier peut être équipé d'une part d'un compteur, tel qu'un compteur à cliquet, qui enregistre le nombre de mouvements monte et baisse réalisés par l'utilisateur, d'autre part, de graduations disposées sur le mât pour permettre à l'utilisateur de visualiser les progrès réalisés en ce qui concerne l'amplitude du mouvement.This mobilization device can be fixed permanently or can be in the form of an autonomous device, installable in any location. In this case, the mast 1 is equipped, at its base 3 and its upper end, with means for fixing and / or guiding the device on any support such as a door edge. The base can, for example, be constituted by a tripod, at least two of the legs of the tripod being equipped with clamping plates which can come to grip the edge of the door. This base is in this case optionally provided with a non-slip system formed for example by pads. The mast head can be equipped with one or more hooks 14 shown in Figure 2 which allow the attachment of the device on a door handle. In addition, to perfect the device, the latter can be equipped on the one hand with a counter, such as a ratchet counter, which records the number of up and down movements made by the user, on the other hand , of graduations arranged on the mast to allow the user to visualize the progress made with regard to the amplitude of the movement.

Enfin, le dispositif est généralement équipé en tête de mât d'une poignée 7 (figure 1) qui est tenue par l'utilisateur au cours de la réalisation des mouvements. Finally, the device is generally fitted at the head of the mast with a handle 7 (FIG. 1) which is held by the user during the making of the movements.
