Abstract
Description
Appareil articulé d'aide â la marche. Articulated walking aid device.
L'invention a pour objet un appareil destiné à faciliter la déambulation et la réadaptation fonctionnelle •de personnes handicapées des membres inférieursThe subject of the invention is an apparatus intended to facilitate walking and functional rehabilitation of persons with disabilities of the lower limbs
On sait que ces personnes souffrent de leur manque d'autonomie. Le sentiment de dépendance de leur entourage aboutit souvent à des effets psychiques défavorables avec perte d'assurance de l'individu et repli vers la solution de facilité qu'est la chaise roulante.We know that these people suffer from their lack of autonomy. The feeling of dependence on those around them often leads to unfavorable psychological effects with loss of self-confidence and withdrawal to the easy solution of the wheelchair.
Il importe donc de fournir aux personnes handicapées des appareils de rééducation appropriés.It is therefore important to provide people with disabilities with appropriate rehabilitation devices.
On trouve sur le marché divers appareils de ce type. Ces appareils se présentent souvent sous la forme d'une cage tubulaire, entourant la personne handicapée sur le devant et sur les côtés jusqu'à hauteur des hanches. Ces dispositifs prennent généralement appui sur le sol par quatre pieds, munis de sabots ou de roulettes. Dans le cas de l'appareil à sabots, le handicapé doit à chaque pas sou¬ lever l'appareil pour le déplacer d'une petite distance, ce qui n'est possible que s'il sait se tenir debout sur ses jambes et s'il est suffisamment valide des membres su¬ périeurs. Selon un perfectionnement connu, l'appareil du type décrit comporte au milieu de la partie avant des arti¬ culations, permettant de déplacer par glissement, en alter¬ nance , les parties de gauche ou de droite du dispositif. Ce perfectionnement permet d'éviter le soulèvement de l'appareil à chaque pas, mais uniquement si l'aire de déambulation ne comporte pas de dénivellation abrupte (bord de trottoir etc.). D'autre part, au moment de pousser une moitié de l'appareil vers l'avant, le handicapé ne peut prendre appui que d'une main sur l'autre moitié qui est alors stationnaire. Cela nécessite une force suffisante dans les deux bras et impose par ailleurs à chaque pas un change¬ ment de la position d'équilibre non seulement dans le sens de la progression, mais encore latéralement. Le remplacement des sabots d'appui par des roulettes se traduit nécessaire¬ ment par une complication de l'appareil, résultant notamment de la nécessité de monter des freins. L'invention a pour but de fournir un appareil d'aide à la marche simple, léger et peu encombrant, qui ne pré¬ sente pas les inconvénients des appareils de l'art anté¬ rieur tout en combinant les avantages d'une grande fiabi¬ lité fonctionnelle et d'une grande stabilité.There are various devices of this type on the market. These devices are often in the form of a tubular cage, surrounding the disabled person on the front and sides up to hip height. These devices are generally supported on the ground by four feet, fitted with shoes or wheels. In the case of the clog device, the handicapped person must at each step lift the device to move it a small distance, which is only possible if he knows how to stand on his legs and stand on his feet. it is sufficiently valid from the upper limbs. According to a known improvement, the device of the type described comprises joints in the middle of the front part, making it possible to move by sliding, in alter¬ nance, the left or right parts of the device. This improvement makes it possible to avoid the lifting of the device with each step, but only if the walking area does not have a steep drop (sidewalk etc.). On the other hand, when pushing one half of the device forward, the disabled person can only support with one hand on the other half which is then stationary. This requires sufficient force in both arms and also imposes at each step a change in the position of equilibrium not only in the direction of progression, but also laterally. The replacement of the support shoes by rollers results in a complication of the apparatus, resulting in particular from the need to mount brakes. The object of the invention is to provide a simple, light and compact walking aid device, which does not suffer from the disadvantages of prior art devices while combining the advantages of great reliability. ¬ functional and highly stable.
A cet effet l'appareil d'aide à la marche, selon l'invention, présente un châssis tubulaire, essentielle¬ ment constitué de deux cadres, l'un antérieur l'autre postérieur, ayant de préférence tous les deux la forme générale d'un "ϋ" renversé, articulés l'un sur l'autre de façon à permettre un pivotement limité d'un cadre par rapport à l'autre autour d'un axe transversal, parallèle aux plans desdits cadres, et solidarisé avec l'un desdits cadres. En position de repos, l'appareil d'aide à la marche prend donc appui au sol par quatre points, à savoir par les extrémités des montants du cadre antérieur et du cadre postérieur. L'élément tubulaire, qui relie les extrémités supérieures des montants du cadre antérieur, sert avanta¬ geusement de poignée d'appui à l'utilisateur. Cette poignée est réglable en hauteur grâce à un système téléscopique avec blocage dans les montants du cadre antérieur. Les éléments mécaniques de la liaison articulée entre le cadre antérieur et le cadre postérieur du châssis tubulaire sont de préférence logés dans des boîtiers de façon à éviter tout accident par accrochage de vêtements.To this end, the walking aid device according to the invention has a tubular frame, essentially consisting of two frames, one anterior the other posterior, preferably both having the general shape of an inverted "ϋ", hinged to each other so as to allow limited pivoting of one frame relative to the other around a transverse axis, parallel to the planes of said frames, and secured to the one of said frames. In the rest position, the walking aid device therefore rests on the ground at four points, namely at the ends of the uprights of the front frame and of the rear frame. The tubular element, which connects the upper ends of the uprights of the front frame, advantageously serves as a support handle for the user. This handle is adjustable in height thanks to a telescopic system with locking in the uprights of the front frame. The mechanical elements of the articulated connection between the front frame and the rear frame of the tubular frame are preferably housed in boxes so as to avoid any accident by snagging of clothing.

Sur ces figures, des éléments analogues portent des repères identiques.- fig. 9 shows another variant of the walking aid device according to the invention. In these figures, similar elements bear identical references.
La fig. 1 montre les montants 1 et 2 du cadre anté¬ rieur, reliés par l'élément tubulaire 3 garni d'un manchon capitonné 5. Les extrémités inférieures des montants 1 et 2 sont munis de sabots antidérapants 4, par exemple en caoutchouc. Les éléments transversaux 9 et 10 (voir aussi fig. 4) font partie du cardre postérieur de l'appareil d'aide à la march selon l'invention. A peu près à mi-hauteur de chaque montant on voit les bords antérieurs du couvercle 7 et du fond 8 des boîtiers d'articulation 13 (voir fig. 4) .fig. 1 shows the uprights 1 and 2 of the anté¬ laughing frame, connected by the tubular element 3 lined with a padded sleeve 5. The lower ends of the uprights 1 and 2 are provided with non-slip shoes 4, for example made of rubber. The transverse elements 9 and 10 (see also FIG. 4) form part of the rear frame of the walking aid device according to the invention. Approximately halfway up each upright, the front edges of the cover 7 and the bottom 8 of the hinge housings 13 can be seen (see FIG. 4).
Dans l'exemple illustré, les boîtiers sont fixés sur les montants (1,2) par soudure le long du bord antérieur de leur fond 8.In the example shown, the boxes are fixed to the uprights (1,2) by welding along the front edge of their bottom 8.
La fig. 2 représente l'appareil selon l'invention en position repliée, les montants de l'élément antérieur étant parallèles à ceux de l'élément postérieur. Ainsi qu'on peut le voir, le couvercle 7 du boîtier 13 comporte un alé¬ sage (19, fig. 5) par lequel passe un bout tubulaire 14' du cadre postérieur. Les lignes pointillées (comme celles de la fig. 3) serviront plus loin à décrire le fonctionnement de l'appareil d'aide à la marche selon l'invention.fig. 2 shows the device according to the invention in the folded position, the uprights of the front element being parallel to those of the rear element. As can be seen, the cover 7 of the box 13 comprises a wise alé¬ (19, fig. 5) through which passes a tubular end 14 'of the rear frame. The dotted lines (like those in FIG. 3) will be used later to describe the operation of the walking aid device according to the invention.
La fig. 3 montre l'appareil selon l'invention, le cadre antérieur ayant basculé en avant d'environ 35 par rapport à l'élément postérieur.fig. 3 shows the device according to the invention, the front frame having tilted forward by approximately 35° with respect to the rear element.
La fig. 4 présente l'ensemble des pièces déjà men¬ tionnées, en perspective. L'élément 9, axe de pivotement de l'appareil, rentre par les fonds 8 dans les boîtiers d'arti- culation 13 et s'emboîte par ses bouts 14 dans des éléments tubulaires 14' portés par les montants (11,12) du cadre postérieur de l'appareil selon l'invention, (voir fig. 5).fig. 4 shows all the parts already mentioned, in perspective. The element 9, pivot axis of the device, enters through the funds 8 in the arti- culation 13 and fits by its ends 14 in the tubular elements 14 'carried by the uprights (11,12) of the rear frame of the device according to the invention, (see Fig. 5).
Les montants postérieurs (11,12) sont stabilisés la¬ téralement par une barre transversale 10. La flèche F indi¬ que l'ajustement vers le bas du niveau de la poignée 5 au moyen du système téléscopique 6.The rear uprights (11,12) are stabilized laterally by a crossbar 10. The arrow F indicates that the downward adjustment of the level of the handle 5 by means of the telescopic system 6.
La fig. 5 présente plus en détail le boîtier 13 et l'articulation utilisés dans l'exemple illustré. Dans cet exemple, chaque montant (1,2) du cadre antérieur de l'appa¬ reil selon l'invention comporte un bo'îtier partiellement fermé 13. Le bord antérieur du fond 8 de chaque boîtier est soudé sur le montant concerné. Le fond 8 est traversé par le bout 14 de l'axe de pivotement 9. Dans le boîtier est par ailleurs incorporée une butée 17 dont l'axe 15 est constitué dans la variante illustrée par une tige filetée 15. Le bout tubulaire 14 s'embôite dans 1'élément tubulaire 14* du mon¬ tant postérieur 11. Chaque montant 11,12 porte également une contrebutëe 18 qui coopère avec la butée 17 pour limiter l'angle maximum du pivotement à une valeur convenable. Le couvercle 7 ferme le boîtier, les alésages 19 et 20 corres¬ pondant respectivement au bout tubulaire 14' et à la tige filetée 15. Le vissage de l'ëcrou 16 sur l'extrémité de la tige filetée 15 permet de maintenir le couvercle en place.fig. 5 shows in more detail the housing 13 and the hinge used in the example shown. In this example, each upright (1,2) of the front frame of the device according to the invention comprises a partially closed case 13. The front edge of the bottom 8 of each case is welded to the relevant upright. The bottom 8 is crossed by the end 14 of the pivot axis 9. In the housing is also incorporated a stop 17 whose axis 15 is constituted in the variant illustrated by a threaded rod 15. The tubular end 14 is Fits into the tubular element 14* of the rear mon¬ 11. Each upright 11,12 also carries a buttress 18 which cooperates with the stop 17 to limit the maximum angle of pivoting to a suitable value. The lid 7 closes the box, the bores 19 and 20 corresponding respectively to the tubular end 14' and to the threaded rod 15. The screwing of the nut 16 on the end of the threaded rod 15 makes it possible to hold the lid in place.
Divers moyens sont à la portée de l'homme du métier pour régler la distance franchie par l'appareil à chaque mouvement de pivotement d'un cadre par rapport à l'autre. On pourrait par exemple visser un boulon à travers un alé¬ sage pratiqué dans le rebord 21 du boîtier ou prévoir des moyens coulissants pour augmenter ou diminuer l'ouverture située au coin en bas du côté droit du boîtier.Various means are available to those skilled in the art for adjusting the distance traveled by the device at each pivoting movement of one frame relative to the other. One could for example screw a bolt through a wise bore made in the flange 21 of the housing or provide sliding means to increase or decrease the opening located at the bottom corner of the right side of the housing.
De même l'on peut prévoir un moyen d'amortissement permettant d'adoucir l'ouverture de l'appareil, c'est-à-dire le basculement de l'un des deux cadres par rapport à l'autre, ce qui permet de rendre l'utilisation plus souple.Similarly, a damping means can be provided to soften the opening of the device, that is to say the tilting of one of the two frames relative to the other, which allows to make it more flexible to use.
La figure 6 montre l'un des boîtiers 13 renfermant un ressort d'amortissement hélicoidal 21 entourant l'élément tubulaire 14' et comportant un premier bras 22 à l'une de ses extrémités attaché à la contrebutëe 18' du montant 11 ou 12 et un second bras 23 venant s'appuyer contre la tige filetée 15. Le ressort hélicoidal 21 rapelle le cadre posté¬ rieur constamment vers sa position parallèle (position re¬ pliée de l'appareil) au cadre antérieur et amortit le bas¬ culement vers l'avant du cadre antérieur. La figure 6 re¬ présente aussi deux boulons réglables 24,25 prévus pour limiter le pivotement d'un cadre par rapport à l'autre dans les deux directions.FIG. 6 shows one of the casings 13 containing a helical damping spring 21 surrounding the tubular element 14' and comprising a first arm 22 at one of its ends attached to the counterbutëe 18 'of the upright 11 or 12 and a second arm 23 coming to rest against the threaded rod 15. The helical spring 21 recalls the posté¬ laughing frame constantly towards its parallel position (re¬ folded position of the apparatus) to the front frame and dampens the forward tilting of the front frame. Figure 6 also shows two re¬ adjustable bolts 24.25 provided to limit the pivoting of a frame relative to the other in both directions.
La figure 7 montre un système d'amortissement à vérin à air comprimé 26 attaché d'un côté à un montant 1,2 du cadre antérieur et de l'autre côté à la contrebutée 18'' d'un montant 11,12 du cadre postérieur.Figure 7 shows a compressed air cylinder damping system 26 attached on one side to an upright 1.2 of the front frame and on the other side to the counterstop 18'' of an upright 11.12 of the frame posterior.
La figure 8 représente une butée d'amortissement 27 en matière élastomère qui peut être utilitsêe au lieu de la butée 17 pour adoucir l'ouverture de l'appareil.Figure 8 shows a damping stop 27 of elastomeric material which can be used instead of the stop 17 to soften the opening of the device.
La figure 9 montre une variante d'exécution de 1'ap¬ pareil d'aide à la marche selon l'invention. L'appareil comporte un seul boîtier d'articulation, monté sur un prolon¬ gement 3' du cadre antérieur en "U" renversé.Figure 9 shows an alternative embodiment of the same walking aid according to the invention. The apparatus comprises a single hinge box, mounted on an extension 3' of the front frame in an inverted "U".
Au départ, l'utilisateur tient l'appareil plus ou moins verticalement (position fig. 2) devant lui en s'ap¬ puyant sur la poignée 5. En tirant les bras en arrière ou en redressant légèrement le buste, l'utilisateur transfère son poids sur les montants du cadre postérieur et, en fai¬ sant jouer l'articulation incorporée dans le boîtier, il bascule le cadre antérieur en avant, dans le sens de la marche, sur un angle de p.ex. 35° (voir fig. 3). En repen¬ chant le buste légèrement en avant, l'utilisateur fait glisser son poids lentement sur les montants antérieurs, piqués en biais sur le sol. Les jambes de l'utilisateur se trouvent alors partiellement dégagées du poids du corps ce qui lui permet d'entraîner ses jambes dans le sens de la marche. Par ce mouvement, l'utilisateur accentue l'appui sur les montants du cadre antérieur en redressant celui-ci simultanément vers la verticale. Les montants du cadre postérieur, dégagés de la charge, basculent vers l'avant autour de l'axe de pivotement et viennent se ranger par gravité parallèlement aux montants du cadre antérieur. Ainsi la position de départ pour le prochain pas est rétablie.Initially, the user holds the device more or less vertically (position fig. 2) in front of him by leaning on the handle 5. By pulling the arms back or by slightly straightening the bust, the user transfers its weight on the uprights of the rear frame and, by acting on the joint incorporated in the casing, it tilts the front frame forward, in the direction of travel, over an angle of e.g. 35° (see Fig. 3). By repen¬ singing the bust slightly forward, the user slides his weight slowly on the front uprights, stitched obliquely on the ground. The user's legs are then partially freed from the weight of the body, which allows him to train his legs in the direction of travel. By this movement, the user accentuates the support on the uprights of the front frame by straightening it simultaneously towards the vertical. The uprights of the rear frame, released from the load, tilt forwards around the pivot axis and are stored by gravity parallel to the uprights of the front frame. Thus the starting position for the next step is restored.
L'appareil d'aide à la marche selon l'invention sert donc en quelque sorte de canne frontale.The walking aid device according to the invention therefore serves as a kind of frontal cane.
La position frontale assure en toutes circonstances un soutien stable. Même si l'utilisateur, pris d'un accès de faiblesse, recule avant d'avoir terminé un pas, les montants du cadre postérieur basculent immédiatement vers l'arrière en rétablissant une position stable sur quatre points d'appui.The frontal position ensures stable support in all circumstances. Even if the user, seized with a fit of weakness, steps back before having completed a step, the uprights of the rear frame tilt immediately backwards, restoring a stable position on four support points.
Diverses modifications peuvent être apportées à 1* appareil décrit. On peut par exemple bloσuer le mouvement de pivotement des cadres en n'importe quelle position in¬ termédiaire par un système à cliquet, incorporé dans le boîtier 13. De telles modifications sont à la portée de l'homme du métier et ne sortent pas du cadre de l'invention. Various modifications can be made to the apparatus described. One can for example bloσuer the pivoting movement of the frames in any intermediate position by a ratchet system, incorporated in the housing 13. Such modifications are within the reach of those skilled in the art and do not depart from the framework of the invention.
