Description
Cet appareil est un dispositif de rééducation, et d'entretien à la marche. This device is a device for rehabilitation, and maintenance in walking.
Il est destiné à aider certaines personnes handicapées ayant des difficultés pour soutenir leur propre poids, à marcher sans pour cela avoir à soulever, ou porter, un appareil quelcon que (canne, béquille, déambulateur) lequel apporte un supplément de poids et afoute à la fatigue, si la distance à parcourir est assez longue. It is intended to help certain handicapped people having difficulties to support their own weight, to walk without for that having to lift, or carry, any device that (cane, crutch, walker) which brings an additional weight and fears the fatigue, if the distance to be covered is long enough.
Cet appareil ne foncticnne qu'en s'appuyant dessus, il n'avance que pas à pas, et comporte un système d'arret automatique de sécurité. This device only works by leaning on it, it advances only step by step, and has an automatic safety stop system.
Eomposé d'un bâti (1) reposant sur quatres roues, dont deux motrices (4) ce bâti supporte deux leviers (2), un ensemble mécanique placé sous carter (5) et une banquette relevable de repos intermittent (8). Consisting of a frame (1) resting on four wheels, two of which drive (4) this frame supports two levers (2), a mechanical assembly placed in the housing (5) and a liftable bench for intermittent rest (8).
L'ensemble mécanique (Fig.3 - vue du dessus) se compose
- d'un engrenage hélicoïdal.The mechanical assembly (Fig. 3 - top view) consists of
- a helical gear.
- d'un disque échancré d'arrêt automatique. - a notched disc with automatic shutdown.
- d'un système d'entraînement. - a drive system.
- d'un systèm de rappel. - a reminder system.
L'engrenage hélicoïdal est composé de dEux roues dentées à dents espacées (3mm. de dents pour 5mm. d'intervalle) la roue dentée motrice, (11) est d'un diamètre double de la roue dentée asservie (26) pour permettre un avancement suffisant, elle comporte e dents. La roue dentée (26) est solidaire des roues motrices (4) par l'intermédiaire de l'axe (6), elle comporte 14 dents. The helical gear is composed of two toothed wheels with spaced teeth (3mm. Of teeth for 5mm. Of interval) the driving toothed wheel, (11) is of a double diameter of the servoed toothed wheel (26) to allow a sufficient advance, it has e teeth. The toothed wheel (26) is integral with the drive wheels (4) via the axis (6), it has 14 teeth.
les dents de cette roue comportent des méplats (27)
Le disque échancré d'arrêt automatique (12) est fixé à demeure sur la roue dentée (11) par soudure (25) ou par boulonnage, il comporte 5 échancrures (13), les parties non échancrées débordent dans l'intervalle des dents de la roue dentée (11) et servent de butoirs d'arrêt (14).the teeth of this wheel have flats (27)
The notched automatic stop disc (12) is permanently fixed to the toothed wheel (11) by welding (25) or by bolting, it has 5 notches (13), the non-scalloped parts protrude in the interval between the teeth of the toothed wheel (11) and serve as stop buffers (14).
Le système d'entraînement est composé de deux leviers à crans (2), de deux mousquetons et de leurs cibles (3), de deux poulies à cliquet à deux gorges chacune (15), de deux roues cliquet (16) solidaires par soudure (25) avec la roue dentée(11) de deux ressorts de cliquet (17), de deux poulies de renvoi (7). The drive system consists of two notched levers (2), two carabiners and their targets (3), two ratchet pulleys with two grooves each (15), two pawl wheels (16) secured by welding (25) with the toothed wheel (11) of two pawl springs (17), of two idler pulleys (7).
Le système de rappel est composé des mêmes deux poulies à cliquet (15), de deux contrepoids et de leurs câbles (20), de deux tubes anti-balancement (19), de deux poulies d'élévation Et d'écartement (18). Le rappel peut être effectue par des ressorts spirales, mais le système par contrepoids exerce une force de pappel quasi-constante. The return system consists of the same two ratchet pulleys (15), two counterweights and their cables (20), two anti-sway tubes (19), two elevation and spacing pulleys (18) . The restoring can be carried out by spiral springs, but the system by counterweight exerts an almost constant pappel force.
Lorsque l'handicapé veut employer l'appareil, il doit exercer une pesée sur le ou les leviers à crans (2), sur chaque levier, repose sur un des crans (2) un-mousqueton (3), ces crans servent à régler la longueur des pas, plus le mousqueton est placé loin de l'axe de levier, plus le pas est long, plus il est placé près de l'axe, plus le pas est court et moins la force demande
Est grande, ce réglage s'effectue quasi instantanément, la course des leviers est limitée par des butées.When the disabled person wants to use the device, he must exert a weight on the lever or notches (2), on each lever, rests on one of the notches (2) a snap hook (3), these notches are used to adjust the length of the steps, the further the carabiner is placed away from the lever axis, the longer the step, the more it is placed near the axis, the shorter the step and the less force required
Is large, this adjustment is carried out almost instantaneously, the stroke of the levers is limited by stops.
Les leviers ont deux fonctions : déverrouiller le système d'arrêt si l'handicapé pousse, et propulser l'appareil. The levers have two functions: unlocking the stop system if the disabled person pushes, and propelling the device.
L'handicapé exerçant une pesée sur le ou les leviers (2) ceux ci, par l'intermédiaire des mousquetons, de leurs cibles et des poulies de renvoi (7) entraînent les poulies à cliquet (15) qui : se mettant en prise, entraînent l'engrenage hélicoïdel (11) lequel fait avancer d'un pas l'appareil. The disabled exerting a weight on the lever (s) (2) these, by means of the carabiners, their targets and return pulleys (7) drive the ratchet pulleys (15) which: engaging, drive the helical gear (11) which advances the device one step.
Les leviers (2) étant appuyés sur les butées basses, l'handicapé est soutenu par eux, etavance un pied ou deux suivant sa convenance, et, recommence. Les leviers se relèvent d'eux même ramenés par le système de rappel. The levers (2) being supported on the lower stops, the handicapped person is supported by them, and advances a foot or two according to his convenience, and, begins again. The levers are raised by themselves brought back by the recall system.
Lorsque l'hendicapé cesse d'appuyer sur les leviers les contrepoids (20) Ecartés du bâti et surélevés (pour assurer une course suffisante) par les poulies (18! ramènent les poulies à cliquet (15) et les leviers (2) à leurs points de ddpart, les contrepoids montent et descendent dans les tubes anti-balancement (19)
Les figues 11 et 12 montrent la disposition des cSbles selon que l'on agit sur le levier droit ou sur le levier gauche.When the disabled person stops pressing the levers the counterweights (20) Spaced from the frame and raised (to ensure sufficient travel) by the pulleys (18! Bring the ratchet pulleys (15) and the levers (2) back to their starting points, the counterweights go up and down in the anti-sway tubes (19)
Figs 11 and 12 show the arrangement of cables depending on whether you act on the right lever or on the left lever.
Disque d'arret automatique de sécurité (12)
Lorsque la roue dentée motrice (11) est entraînée (FIg.5) elle applique une de ses dents contre une des dents de la roue dentée (26) et fait tourner celle-ci, dans cette rotation, les dents de cette dernière passent par l'échancrure (13) du disque d'arrêt (petite flèche) le mouvement n'est pas entravé. flàche trait plein = sens rotation roue motrice, (11) et flèche en pointillé = sens rotation roue menée (26). Automatic safety stop disc (12)
When the drive gear (11) is driven (FIg.5) it applies one of its teeth against one of the teeth of the gear (26) and rotates the latter, in this rotation, the teeth of the latter pass through the notch (13) of the stop disc (small arrow) the movement is not hampered. solid line arrow = driving wheel rotation direction, (11) and dotted arrow = driven wheel rotation direction (26).
in n'actionnant plus les leviers, la roue dentée (11)est immobilisée (Fig.6), si l'handicapé trébuche ou pousse par inadvertance sur le bâti, celui-ci avance légèrement, fait tourne; la roue dentée (26) dans l'intervalle des dents de la roue dentée (11) une dent de la roue (26) pousse sur une dent de la roue (11), celle-ci n'offrant aucune résistance à la rotation tourne jusqu'à ce que le méplat (27)bute sur la face d'arrêt (14)du disque d'ar r8t de sécurité (12)l'avance de l'appareil est bloquée, et tout accident évité, la petite fiche pleine indique le sens de la poussée (Fig. 7). by no longer operating the levers, the toothed wheel (11) is immobilized (Fig. 6), if the disabled person stumbles or inadvertently pushes on the frame, the latter advances slightly, turns; the toothed wheel (26) in the interval of the teeth of the toothed wheel (11) a tooth of the wheel (26) pushes on a tooth of the wheel (11), this one offering no resistance to rotation turns until the flat (27) abuts on the stop face (14) of the safety rear disc (12) the advance of the device is blocked, and any accident avoided, the small full plug indicates the direction of the push (Fig. 7).
Les leviers étant indépendants l'un de l'autre, l'appareil peut être utilise de différentes manières à la convenance de l'utilisateur. The levers being independent of each other, the device can be used in different ways at the convenience of the user.
Les deux leviers simultanément,
Les deux leviers alternativement, il est toujours soutenu.The two levers simultaneously,
The two levers alternately, it is always supported.
Si l'utilisateur a une faiblesse plus marquée pour une jambe, il aura tendance à se soutenir de ce côté, et actionnera donc toujours le levier du côté opposé, il sera toujours soutenu. If the user has more marked weakness for one leg, he will tend to support himself on this side, and therefore will always operate the lever on the opposite side, he will always be supported.
Vu la stabilité de l'appareil, Et vu que l'on ne soulève riEn, il peut être utilisé par une personne n'ayant qu'un bra ve- lide et par un unidambiste. In view of the stability of the device, and since it is not lifted, it can be used by a person with only a mobile bra and by a one-to-one.
Si l'appareil est bloqué, pour débloquer : deux moyens
1) Tirer légèrement l'appareil en arrière.If the device is blocked, to unlock: two ways
1) Pull the device slightly back.
2) appuyer plus fortement sur le ou les leviers cela entraine la rotation du disque d'arrêt (12) une surface d'arrêt (14) glisse sur un méplat (27) quand celui ci se trouve face à une échancrure (13) l'avance est libérée. 2) press more strongly on the lever (s) this causes the rotation of the stop disc (12) a stop surface (14) slides on a flat (27) when the latter is facing a notch (13) l advance is released.
La position oblique des poignées de levier (2) par rapport à la direction de marche oblige l'handicapé à appuyer d'avantage qu'il ne pousse. The oblique position of the lever handles (2) relative to the direction of travel obliges the disabled to press more than it pushes.
Une banquette relevable (8) montée sur charnière (31)est suspendue sur le montant arrière droit et permet un repos intermittent, en relevant cette banquet-te, le bout soulève la plaquette loquet (26) laquelle, projetée contre le butoir caoutchouc (30) retombe sur son support (29), en abaissant la banquette (e) celle ci se pose sur la plaquette loquet (26) Fis. B et 9. A hinged seat (8) mounted on hinge (31) is suspended on the right rear upright and allows an intermittent rest, by raising this banquet-te, the end raises the latch plate (26) which, projected against the rubber stopper (30 ) falls back on its support (29), by lowering the seat (e) this is placed on the latch plate (26) Fis. B and 9.
La direction de l'appareil est assurée en le faisant riper dans la direction désirée par une legère poussée des hanches, soit à droite, soit à gauche sur les montants arrières de l'appa- reil, l'handicapé se soutenant toujours sur les leviers. The direction of the device is ensured by causing it to slide in the desired direction by a slight push of the hips, either to the right or to the left on the rear uprights of the device, the disabled person still supporting himself on the levers .
Les pièces (22) sont d-es rondelles d'écartement, et d'usure libres de rotation. The parts (22) are d-es spacers, and wear free to rotate.
D'ap-rès un prototype construit, la longueur des pas varie de 10 à 30 Cm. et la puissance demandée faible. According to a prototype built, the length of the steps varies from 10 to 30 Cm. and the requested power low.
Le Déplacement rapide de appareil par le personnel assistant s'éffectue en basculant l'apparil sur les roues arriè- res, lesquelles sont à rotation libre. The rapid movement of the device by the assistant personnel is effected by tilting the device on the rear wheels, which are freely rotating.
