Le dispositif à déplacement par autopropulsion comprend deux parties : la première représente le support supérieur et la deuxième partie représente le support inférieur.The self-propelling displacement device comprises two parts: the first represents the upper support and the second part represents the lower support.
Le support supérieur est logé dans une encoche appropriée du support inférieur où il peut se déplacer par glissement. La surface de dessus du support supérieur est munie d'éléments connus d'attachement de la chaussure, des sangles par exemple, dont l'attachement de l'avant-pied doit être fixe, rigide, tandis que le deuxième attachement au niveau du talon peut être souple, extensible, donnant la possibilité à la cheville de remonter et, de ce fait, de faciliter la marche. Les deux supports peuvent avoir différentes configurations à condition d'assurer le déplacement rectiligne de l'un par rapport à l'autre. Les deux côtés latéraux du support inférieur possèdent des rainures longitudinales de guidage d'un ensemble d'axes mobiles. Les axes sont assemblés réunis à des rouleaux cylindriques en produisant une « chaîne ». Le premier bout de ladite chaîne est fixé sur l'extrémité du support inférieur, le deuxième bout de la chaîne est fixé sur l'extrémité du support supérieur opposé. Les deux fixations ne permettent que le pivotement des éléments de l'articulation de la chaîne. Deux rouleaux cylindriques, au moins, des deux extrémités de la chaîne sont unidirectionnels : ils ne tournent qu'en direction de l'avancement du dispositif.The upper support is housed in a suitable slot in the lower support where it can move by sliding. The top surface the upper support is provided with known elements of attachment of the shoe, straps for example, the attachment of the forefoot must be fixed, rigid, while the second attachment at the heel can be flexible, expandable, giving the ankle the opportunity to go up and, therefore, to make walking easier. The two supports can have different configurations provided that the rectilinear movement of one relative to the other. The two lateral sides of the lower support have longitudinal grooves for guiding a set of movable axes. The shafts are assembled together with cylindrical rollers producing a "chain". The first end of said chain is fixed on the end of the lower support, the second end of the chain is fixed on the end of the opposite upper support. The two fasteners allow only the pivoting elements of the articulation of the chain. At least two cylindrical rollers of the two ends of the chain are unidirectional: they rotate only in the direction of advancement of the device.
Lors du fonctionnement du dispositif, au moment où le poids de l'utilisateur est posé sur le dispositif, la chaîne s'aplatit, en se dépliant, tous les rouleaux cylindriques et les axes mobiles avancent, faisant avancer à leur tour le support supérieur, en entraînant la chaussure de l'utilisateur fixée dessus, tandis que le support inférieur reste immobile.During the operation of the device, at the moment when the weight of the user is placed on the device, the chain flattens, by unfolding, all the cylindrical rollers and the moving axes advance, advancing in turn the upper support, by dragging the user's shoe fixed on it, while the lower support remains motionless.
Des moyens sont prévus, tels que des ressorts pour rappeler le support supérieur lorsque le dispositif quitte le sol.Means are provided, such as springs for biasing the upper support as the device leaves the ground.
Le dispositif est muni d'un système connu de freinage partiel de la rotation des rouleaux, une barre avec les ressorts par exemple, afin d'éviter le mouvement de roulement incontrôlé du dispositif et d'assurer la stabilité de l'utilisateur lors de la marche.The device is provided with a known partial braking system of the rotation of the rollers, a bar with the springs for example, in order to avoid the uncontrolled rolling movement of the device and to ensure the stability of the user during the walk.
Dans une des variantes du dispositif, le système de freinage des rouleaux est réglable, permettant d'utiliser le dispositif en tant que patin, pour descendre des pentes par exemple. La barre, avec les ressorts, prévue pour cette occasion, peut être plus ou moins appliquée contre les rouleaux.In one of the variants of the device, the braking system of the rollers is adjustable, making it possible to use the device as a pad, to go down slopes for example. The bar, with springs, provided for this occasion, can be more or less applied against the rollers.
Le cas échéant, il est prévu le verrouillage du dispositif par une des structures connues, un crochet par exemple. Un bourrelet rétractable à l'extrémité antérieure est prévu afin d'assurer l'horizontalité de la surface supérieure du dispositif une fois le dispositif verrouillé.If necessary, the device is locked by one of the known structures, for example a hook. A retractable bead at the front end is provided to provide the horizontality of the upper surface of the device once the device is locked.
D'autres caractéristiques et avantages de la présente invention apparaîtront plus clairement à la lecture de la description faite en se référant aux dessins annexés à titre d'exemple indicatif seulement sur lesquels :Other characteristics and advantages of the present invention will appear more clearly on reading the description made with reference to the accompanying drawings by way of example only, in which:
- la fig.l est une vue en perspective du dispositif ;- Fig.l is a perspective view of the device;
- la fig.2 représente une section transversale d'une version plus élaborée du dispositif ;- Fig.2 shows a cross section of a more elaborate version of the device;
- la fig.3 représente schématiquement le bourrelet rétractable dans les deux états : opérationnel pour la marche avec le dispositif verrouillé (I) et rétracté (II) pour le dispositif en fonction d'accélération de la vitesse de la marche ;FIG. 3 schematically represents the retractable bead in the two states: operational for walking with the locked device (I) and retracted (II) for the device as a function of accelerating the speed of gait;
- la fig.4 représente schématiquement le dispositif en état de repos, le pied est en l'air ;- Figure 4 shows schematically the device in a state of rest, the foot is in the air;
- la fig.5 représente schématiquement le dispositif avec la chaussure au moment où le pied touche le sol ;- Figure 5 schematically shows the device with the shoe when the foot touches the ground;
- la fig.6 représente schématiquement le dispositif avec la chaussure en position sur le sol ;- Fig.6 schematically shows the device with the shoe in position on the ground;
- la fig.7 représente schématiquement le dispositif avec la chaussure au moment où le pied quitte le sol.- Figure 7 schematically shows the device with the shoe as the foot leaves the ground.
En se reportant à la figure 1 , on voit que le dispositif est constitué de deux parties, le support supérieur 1 et le support inférieur 2. Le support supérieur à une section transversale en forme de T renversé et il est muni de deux moyens d'attachement de la chaussure situés sur la surface supérieure dudit support. Le moyen d'attachement 3 est souple, extensible, et permet de remonter la cheville lors de la marche. Le moyen d'attachement 4 est rigide et assume la fixation immobile de l'avant-pied de la chaussure. Le support supérieur 1 possède un moyen connu de verrouillage du dispositif, un crochet 5 par exemple. A l'extrémité antérieure du support 1 se trouve un axe fixe 6 sur lequel s'articule une biellette 7. Le support inférieur 2 représente une structure de réception de tous les éléments du dispositif. Il est muni d'une encoche longitudinale appropriée par sa configuration à loger le support 1 . Les deux côtés latéraux du support 2 possèdent des rainures longitudinales 2a de guidage où l'ensemble des axes 8 est logé. A l'extrémité postérieure du support inférieur 2 est disposé un axe fixe 9. Les axes 8 peuvent se déplacer tout au long des rainures longitudinales 2a. Des rouleaux 10, montés sur des axes 1 1 sont reliés aux axes 8 par des biellettes 7a, analogues à celle 7.With reference to FIG. 1, it can be seen that the device consists of two parts, the upper support 1 and the lower support 2. The upper support has an inverted T-shaped cross section and is provided with two means of attachment of the shoe located on the upper surface of said support. The attachment means 3 is flexible, stretchable, and allows to raise the ankle when walking. The attachment means 4 is rigid and assumes the fixed attachment of the forefoot of the shoe. The upper support 1 has a known means of locking the device, a hook 5 for example. At the front end of the support 1 is a fixed axis 6 on which a rod 7 is articulated. The lower support 2 represents a structure for receiving all the elements of the device. It is provided with a longitudinal notch appropriate for its configuration to accommodate the support 1. The two lateral sides of the support 2 have longitudinal guide grooves 2a where all the pins 8 are housed. At the rear end of the lower support 2 is arranged a fixed axis 9. The axes 8 can move along the longitudinal grooves 2a. Rollers 10 mounted on shafts 1 1 are connected to shafts 8 by links 7a, similar to that 7.
Des moyens sont prévus pour assurer le resserrement du dispositif à l'état de repos. Des ressorts 1 2, reliant les biellettes, sont destinés à resserrer le dispositif en état de repos, quand le dispositif se trouve en l'air. Au moins deux rouleaux cylindriques, le premier et le dernier, sont unidirectionnels et ne peuvent tourner qu'en direction de l'avancement du dispositif. Une barre de freinage 1 3, reliée à la partie inférieure du support 2 par des ressorts 14, assure le freinage partiel de la rotation des rouleaux 10.Means are provided to ensure the tightening of the device in the idle state. Springs 1 2, connecting the rods, are intended to tighten the device in the state of rest, when the device is in the air. At least two cylindrical rollers, the first and the last, are unidirectional and can only rotate in the direction of advancement of the device. A braking bar 1 3, connected to the lower part of the support 2 by springs 14, provides partial braking of the rotation of the rollers 10.
La fig.2 représente une variante du dispositif. Le principe de fonctionnement reste toujours le même. Le support supérieur 1 est construit selon une autre configuration afin d'assumer la meilleure adhésion à la semelle et au talon de la chaussure. Le dispositif décrit ci- dessus est incorporé dans la semelle et le talon 1 5 de la chaussure en le dissimulant le mieux possible pour respecter l'aspect esthétique de la chaussure. La fig. 3 représente schématiquement le principe de fonctionnement du bourrelet. La position I montre le bourrelet 1 6 en position de fonctionnement lors du verrouillage du dispositif, où il est retenu à l'aide du ressort 1 7 en état stable. La hauteur du bourrelet, qui se trouve au niveau de l'avant-pied à l'extrémité de la planche 1 par rapport à la hauteur du dispositif au niveau du talon, est choisie de manière à assurer l'horizontalité de la surface supérieure du dispositif et obtenir la meilleure commodité lors de la marche avec le dispositif verrouillé. Lors de la marche, avec le dispositif déverrouillé, il suffit de passer de la position I à celle II en faisant pivoter le bourrelet 1 6 autour de l'axe 18 en l'escamotant dans l'encoche 1 9, où il est retenu à l'aide du ressort 17 en position stable également.Fig.2 shows a variant of the device. The operating principle remains the same. The upper support 1 is constructed in another configuration to assume the best adhesion to the sole and heel of the shoe. The device described above is incorporated in the sole and heel 1 5 of the shoe concealing the best possible to respect the aesthetic appearance of the shoe. Fig. 3 schematically shows the principle of operation of the bead. The position I shows the bead 1 6 in the operating position during locking of the device, where it is retained by means of the spring 1 7 in steady state. The height of the bead, which is at the level of the forefoot at the end of the board 1 relative to the height of the device at the heel, is chosen so as to ensure the horizontality of the upper surface of the device and get the best convenience when walking with the device locked. When walking, with the unlocked device, simply move from position I to II by rotating the bead 1 6 around the axis 18 by retracting into the notch 1 9, where it is retained at using the spring 17 in a stable position as well.
La fig.4 représente schématiquement le dispositif, la chaussure n'ayant aucun contact avec le sol. Le dispositif est complètement serré.Fig.4 shows schematically the device, the shoe having no contact with the ground. The device is completely tight.
La fig.5 représente schématiquement le dispositif avec la chaussure en position sur le sol. Le poids de l'utilisateur commence à être appliqué sur le dispositif.Fig.5 schematically shows the device with the shoe in position on the ground. The weight of the user begins to be applied to the device.
La fig.6 représente schématiquement le dispositif lorsque la chaussure est en appui sur le sol : la chaussure s'est déplacée vers l'avant.Figure 6 shows schematically the device when the shoe is supported on the ground: the shoe has moved forward.
La fig.7 représente schématiquement le dispositif avec la chaussure au moment où le pied quitte le sol. C'est le moment où le pas précédent est terminé et où commence le pas suivant. Cette figure montre que l'utilisateur prend appui sur l'avant-pied, exactement comme il l'aurait fait en marche sans dispositif.Fig.7 shows schematically the device with the shoe as the foot leaves the ground. This is the moment when the previous step is finished and the next step begins. This figure shows that the user is supported on the forefoot, exactly as he would have done without a device.
Pour comprendre le fonctionnement du dispositif on se réfère aux figures 4 à 7 sur lesquelles A schématise l'extrémité postérieure du support 2 et B celle antérieure du support 1. Les deux parties 1 et 2 sont déverrouillées et les ressorts 1 2 rappellent celles-ci l'une vers l'autre. La distance AB est courte (fig.4) En posant le talon sur le sol (fig.5), tout le poids du corps repose sur le cylindre postérieur et l'ensemble des biellettes se déplace vers l'avant. La chaussure pivote, le dispositif prend appui contre le sol et la distance AB augmente (fig.6).To understand the operation of the device, reference is made to FIGS. 4 to 7 in which A schematizes the rear end of the support 2 and B that of the support 1. The two parts 1 and 2 are unlocked and the springs 1 2 recall these towards each other. The distance AB is short (fig.4) By placing the heel on the ground (fig.5), the whole weight of the body rests on the rear cylinder and all the links move forward. The shoe pivots, the device bears against the ground and the distance AB increases (fig.6).
A la fin du mouvement, la chaussure bascule vers son extrémité antérieure (fig.7) et le point A, sous l'effet des ressorts 1 1 commence à se rapprocher de celui B. On constate donc que lorsque le point B va quitter le sol il le fera à une distance à une distance supérieure à celle qui séparait initialement les points A et B (fig4).At the end of the movement, the shoe tilts towards its anterior end (fig.7) and the point A, under the effect of the springs 1 1 begins to approach that B. Thus, when the point B will leave the it will do so at a distance greater than that which initially separated the points A and B (fig4).
Durant la phase où le dispositif est en appui contre le sol (fig.6), les rouleaux prennent appui contre la barre 13, en comprimant les ressorts 14, ce qui les freine. During the phase in which the device bears against the ground (FIG. 6), the rollers bear against the bar 13, compressing the springs 14, which brakes them.
