Abstract

The sole in an orthopaedic shoe with a raising tip is lifted from the ground and moved forward. The lifting movement is achieved by a force (F2) applied on the free end (2) of a thin metal plate. This metal plate is also flexible and elastic and is situated under the shoe (I). One end of the plate is fixed to the shoe of the tip and the other is free and its extreme end (2) is linked up with the heel (6) where a thrust system (4) is located. The shoe is useful to people with deformed feet and with varying handicaps involving loss of balance. The tip is raised automatically each time the foot is not supporting the body wt. The tip can also be designed to fit any foot by adapting it to raise over only one half or the whole width of the sole or to twist it.

Description

L'invention concerne une chaussure orthopédique; une lame metallique fine, flexible et élastique est prevue sous la semelle avec la partie la plus proche de la pointe de la chaussure, fixée à la semelle et celle la plus proche du talon, libre par rapport de la semelle, mais à un dispositif de poussée vers la pointe de la chaussure, dissimulé dans le talon; la force appliqué à la libre extrémité de la lame a un effect actif dirigé vers le sol qui provoque le soulèvement de la pointe de la chaussure lorcequele pied est soulevé de terre.The invention relates to an orthopedic shoe; a thin, flexible and elastic metal blade is provided under the sole with the part closest to the toe of the shoe, attached to the sole and that closest to the heel, free with respect to the sole, but with a device for pushed towards the tip of the shoe, hidden in the heel; the force applied to the free end of the blade has an active effect directed towards the ground which causes the tip of the shoe to lift up when the foot is lifted off the ground.

On sait que pendant la locomotion, les membres inférieurs du corps hamain sont tous deux actifs et, pendant que l'un, s'appuyant sur le sol, soutient le poids du corps et pousse en avant et vers le haut son centre de gravité, l'autre se raccourcit pour accomplir un mouvement pendulaire et se porter en avant; à ceci coopèrent les muscles fléchisseurs de la cuisse ainsi que les groupes musculaires qui, plus précisément, agissent sur le pied pour son extension.We know that during the locomotion, the lower limbs of the hamain body are both active and, while one, leaning on the ground, supports the weight of the body and pushes its center of gravity forward and upwards, the other shortens to perform a pendulum movement and to move forward; the flexor muscles of the thigh and the mu groups cooperate with this. more specifically, act on the foot for its extension.

Quand cette dite extension fait défaut ou est insuffisante comme, par exemple, chez les hémiplégiques, paraplégiques, handicapés moteur et sujets à paralysies flasques ou autres infirmités ou malformations des membres inférieurs, on constate, pendant la progression, que la pointe du pied frotte par terre, ce qui est la cause de fréquentes chutes. La présente invention a pour but de proposer un remède à la difficulté de déambulation de ces sujets,When this said extension is lacking or insufficient such as, for example, in hemiplegics, paraplegics, motor handicapped and prone to flaccid paralysis or other infirmities or malformations of the lower limbs, it is noted, during the progression, that the tip of the foot rubs by earth, which is the cause of frequent falls. The object of the present invention is to propose a remedy for the difficulty of wandering these subjects,

Cette invention, telle qu'elle est caractérisée dans les revendications, resoud le problème, consistant à provoquer le soulèvement automatique de la pointe de la chaussure alors que le pied de celui qui la chaus se est dégagé du poids du corps et doit, pendant la locomotion, être porté en avant.This invention, as characterized in the claims, solves the problem of causing automatic lifting of the toe of the shoe when the foot of the shoe is released from the weight of the body and must, during the locomotion, to be carried forward.

Ceci est obtenu à l'aide d'une lame résistante, flexible et élastique, se situant sous la semelle, dont la partie la plus proche de la pointe de la chaussure est fixée à la semelle et, celle la plus lointaine est libre et reliée à un dispositif de poussée vers la pointe de la chaussure, dissimulé dans le talon. Les avantages obtenus grâce à cette invention consistent en ceci que la pointe de la chaussure est soulevée automatiquement chaque fois que la chaussure est dégagé du poids du corps; que le dit soulèvement peut concerner toute la largeur de la semelle ou, d'une façon préeminante, seulement une moitié, en fonction de l'infirmité du pied du porteur; que le soulèvement peut comporteraussi une torsion de la semelle, ce qui est d'une grande utilité en cas de pieds équins, varus ou avec supination.This is obtained using a resistant, flexible and elastic blade, located under the sole, the part closest to the toe of the shoe is fixed to the sole and, the most distant part is free and connected a pushing device towards the tip of the shoe, hidden in the heel. The advantages obtained thanks to this invention consist in that the toe of the shoe is lifted automatically each time the shoe is released from the weight of the body; that said lifting may concern the entire width of the sole or, pre-eminently, only half, depending on the infirmity of the wearer's foot; that the lifting may also involve a twisting of the sole, which is of great help in the event equine, varus or supine feet.

Sa constitution de base comprend une chaussure de forme et structure substantiellement usuelles, où sur la partie inférieure de la semelle (1) est appliquée une lame (2) métallique, fine mais robuste, flexible et élastique dont la partie la plus proche de la pointe de la chaussure est fixée, à l'aide de moyens connus, à la semelle (1), alors que l'autre partie, qui est opportunément restreinte vers l'extrémité, est libre et donc susceptible de se détacher de la semelle sous l'effet d'une force de poussée latérale dirigée vers le bas et appliquée à son extrémité; d'une sous-semelle (3) ayant la fonction de couvrir la face de la lame (2) dirigée vers le sol et de consentir une surface antidérapante; d'un dispositif de poussée de la dite lame (2) comprénant au moins: un ressort (4) de type à compression, logé dans un tube (5) fixé dans le talon (6), ce ressort (4) transmettant son action de compression à la lame (2) par l'intermédiaire d'un piston (7) et d'une biellette (8) profilée de telle façon qu'elle est dissimulée sous la voûte centrale (9) de la chaussure et reliée à une extrémité directement au piston et à l'autre, à l'extrémité (2' ) de la lame (2) au mayen d'un charnière.Its basic constitution includes a shoe of substantially usual shape and structure, where on the lower part of the sole (1) is applied a metal blade (2), thin but robust, flexible and elastic, the part closest to the toe of the shoe is fixed, using known means, to the sole (1), while the other part, which is conveniently restricted towards the end, is free and therefore capable of detaching from the sole under the effect of a downward sideways pushing force applied to its end; a sub-sole (3) having the function of covering the face of the blade (2) directed towards the ground and of providing a non-slip surface; of a pushing device of said blade (2) comprising at least: a spring (4) of compression type, housed in a tube (5) fixed in the heel (6), this spring (4) transmitting its action of compression to the blade (2) by means of a piston (7) and of a rod (8) profiled in such a way that it is hidden under the central arch (9) of the shoe and connected to a end directly to the piston and to the other, at the end (2 ') of the blade (2) at the end of a hinge.

Il va de soi que le dit ressort (4) a des dimensions adéquates en relation à la poussée que l'on veut obtenir et qu'il est variable en fonction de l'infirmité et du poids de celui qui porte la chaussure. Avec le pied soulevé de terre et donc dégagé, la force F1 avec laquelle le ressort (4) en extension agit sur la lame (2) a une composante F2 dans l'extrémité libre (2') de la lame, laquelle résulte tran sversale ou oblique à la lame et dirigée vers le bas: ceci détermine le soulévement de la pointe de la chaussure.It goes without saying that the said spring (4) has adequate dimensions in relation to the thrust that one wants to obtain and that it is variable depending on the infirmity and the weight of the person wearing the shoe. With the foot raised from the ground and therefore cleared, the force F1 with which the spring (4) in extension acts on the blade (2) has a component F2 in the free end (2 ') of the blade, which results in transverse tran or oblique to the blade and directed downwards: this determines the uplift of the tip of the shoe.

Au contraire, avec le pied appuyé par terre et chargé du poids P1 du corps, la composante F2 est dirigée vers le haut et le ressort (4) est comprimé dans son logement.On the contrary, with the foot pressed on the ground and loaded with the weight P 1 of the body, the component F2 is directed upwards and the spring (4) is compressed in its housing.

L'axe longitudinal du ressort (4) et de la biellette (8) résultent en un plan qui a pour tracé l'axe longitudinal YY de la chaussure (exemple illustré à la Fig. 4), ce qui fait que la pointe de la chaussure subit un simple soulévement par rotation autour de l'axe transversal XX; ou bien en un plan paralléle à celui-ci ou bien oblique (exemple illustré à la Fig. 5) ce qui fait que la pointe dela chaussure subit un soulèvement avec torsion par effet de'la rotation autour de l'axe X'X'.The longitudinal axis of the spring (4) and of the link (8) results in a plane which has the longitudinal axis YY of the shoe as its outline (example illustrated in FIG. 4), so that the tip of the shoe undergoes a simple lifting by rotation about the transverse axis XX; or in a plane parallel to it or oblique (example illustrated in Fig. 5) so that the tip of the shoe undergoes a lifting with torsion by effect of 'rotation around the axis X' X ' .

En outre la partie de lame (2) destinée à être fixée à la semelle (1) a une extension variable en largeur afin d'être étendue sur toute la largeur de la semelle ou bien sur une partie qui peut être centrale ou latéralepar rapport à la semelle.Furthermore, the blade part (2) intended to be fixed to the sole (1) has a variable width extension in order to be extended over the entire width of the sole or else on a part which may be central or lateral with respect to the sole.
