Description

La présente invention concerne une chaussure comportant des roulettes intégrées à la semelle et dépliables latéralement au moyen d'un mécanisme. Cette chaussure peut servir alternativement pour la marche et pour le roulage.The present invention relates to a shoe having wheels incorporated in the sole and laterally unfoldable by means of a mechanism. This shoe can be used alternately for walking and driving.

La présente invention concerne plus particulièrement des chaussures qui comportent une à quatre roulettes, placées pour la marche à l'horizontale dans des logements de la semelle, et qui pour le roulage, peuvent être pivotées par rotation autour d'un axe longitudinal et bloquées en position sensiblement verticale faisant saillie vers le bas de chaque coté de la semelle et transformant ainsi la chaussure en patin à roulettes.The present invention relates more particularly to shoes which comprise one to four wheels, placed for walking horizontally in housing of the sole, and which for rolling, can be pivotally rotated about a longitudinal axis and locked in substantially vertical position projecting downward on each side of the sole and thus transforming the shoe roller skate.

Dans la vie de tous les jours, on passe successivement par des endroits et des moments où il faut pouvoir marcher aisément, et d'autres où il est intéressant de pouvoir rouler dans de bonnes conditions, sans avoir à changer d'équipement ou à transporter des accessoires.In everyday life, we pass successively through places and moments where we must be able to walk easily, and others where it is interesting to be able to ride in good conditions, without having to change equipment or to transport accessories.

Il est donc utile de disposer de chaussures esthétiques et pratiques, mais également polyvalentes et permettant de passer facilement d'un mode d'utilisation à l'autre.It is therefore useful to have shoes aesthetic and practical, but also versatile and to switch easily from one mode of use to another.

On connaît les chaussures selon WO 01/85271 A1 qui peuvent être transformées en rollers mais qui sont relativement lourdes et complexes. En raison de la disposition en ligne des roues, ces chaussures doivent monter au dessus de la cheville de façon à protéger et à maintenir le pied. Il n'est pas aisé de marcher avec ce type de chaussures, dont la semelle est d'autre part rendue rigide par le mécanisme.We know the shoes according to WO 01/85271 A1 which can be turned into rollers but are relatively heavy and complex. Due to the in-line layout of the wheels, these shoes must rise above the ankle to protect and maintain the foot. It is not easy to walk with this type of shoes, whose sole is also made rigid by the mechanism.

On connaît également les chaussures selon CN 2306039 Y . La semelle est relativement rigide en raison de la platine métallique et ne peut pas se déformer librement pendant la marche. Le mécanisme situé sous la semelle peut s'encrasser et le poids de l'ensemble est relativement élevé.We also know the shoes according to CN 2306039 Y . The soleplate is relatively rigid because of the metal plate and can not deform freely during walking. The mechanism under the soleplate can become dirty and the overall weight is relatively high.

DE 297 17 652 U1 décrit le préambule de la revendication principale 1. DE 297 17 652 U1 describes the preamble of main claim 1.

L'invention s'est fixée comme but de réaliser des chaussures transformables, légères mais robustes, avec une semelle mince et souple pouvant se déformer librement pendant la marche, avec des roulettes de grand diamètre et un dispositif de commande unique et simple. L'invention peut s'adapter à tout type de chaussures, avec ou sans maintien de la cheville. Les chaussures à roulettes selon l'invention permettent de passer très rapidement et facilement de la marche au roulage, et vice-versa et elles conviennent parfaitement aux deux utilisations.The object of the invention is to provide transformable shoes, light but robust, with a thin and flexible sole that can deform freely during walking, with large diameter wheels and a single and simple control device. The invention can adapt to any type of shoes, with or without ankle support. The roller shoes according to the invention make it possible to move very quickly and easily from walking to rolling, and vice versa and they are ideal for both uses.

Il est notamment possible de choisir selon l'usage prévu, le diamètre et la largeur des roues, leur écartement et leur position par rapport au talon, la hauteur de la semelle par rapport au sol en position de roulage, le mécanisme de fixation et de blocage des roues, etc. De préférence, la semelle équipée des roulettes ne présente vers le sol que des surfaces fermées revêtues de caoutchouc n'offrant qu'un faible risque d'encrassement.It is in particular possible to choose according to the intended use, the diameter and the width of the wheels, their spacing and their position relative to the heel, the height of the soleplate with respect to the ground in the rolling position, the fixing mechanism and the wheel lock, etc. Preferably, the soleplate equipped with the rollers presents to the ground only closed surfaces coated with rubber offering only a low risk of fouling.

Le mécanisme selon l'invention, servant à fixer les roulettes à la chaussure, permet un blocage efficace et sûr des roulettes en position de roulage et en position de marche, sans jeu ni vibration, et un passage rapide, sans effort et sans outil d'une position à l'autre.The mechanism according to the invention, used to attach the casters to the boot, allows effective and safe locking of the casters in the rolling position and in the running position, without play or vibration, and a quick passage, without effort and without tools. one position to another.

Pour résoudre ce problème technique, l'invention enseigne une chaussure polyvalente destinée alternativement à la marche ou au roulage, comportant une semelle dans laquelle sont ménagés des logements ; des roulettes, qui pour la marche sont escamotées en position horizontale dans les logements de la semelle et pour le roulage sont déployées sous la semelle en position verticale ; et un mécanisme d'actionnement des roulettes permettant de faire passer les roulettes alternativement d'une position à l'autre par pivotement latéral.To solve this technical problem, the invention teaches a versatile shoe intended alternately for walking or driving, comprising a sole in which are provided housing; casters, which for walking are retracted in a horizontal position in the housing of the sole and for rolling are deployed under the sole in vertical position; and a mechanism for actuating the rollers for moving the rollers alternately from one position to the other by lateral pivoting.

Selon l'invention, en position verticale de roulage, les roulettes sont disposées de part et d'autre de la semelle à la façon d'un patin à roulettes.According to the invention, in the vertical rolling position, the rollers are disposed on either side of the sole in the manner of a roller skate.

En outre, le mécanisme d'actionnement des roulettes comprend :

  • deux axes longitudinaux disposés chacun d'un côté de la chaussure et fixés à la semelle par l'intermédiaire de paliers leur permettant de pivoter sur eux-mêmes, ces axes longitudinaux portant de façon solidaire en rotation les roulettes situées du même côté de la chaussure ;
  • deux éléments tournants placés à l'arrière de la chaussure, chacun étant solidaire en rotation de l'un des axes longitudinaux et étant susceptible de pivoter entre deux positions limites correspondant pour l'une à la position horizontale de marche des roulettes et pour l'autre à la position verticale de roulage des roulettes ;
  • un dispositif de blocage angulaire des éléments tournants, qui lorsqu'il est déverrouillé libère les éléments tournants et autorise leur libre rotation sous l'effet du poids ou d'un effort s'exerçant sur les roulettes, les axes longitudinaux ou les éléments tournants, et qui lorsqu'il est verrouillé bloque simultanément les éléments tournants dans l'une de leurs positions limites.
In addition, the mechanism for actuating the rollers comprises:
  • two longitudinal axes each arranged on one side of the shoe and fixed to the sole by means of bearings allowing them to pivot on themselves, these longitudinal axes bearing in rotation the rollers on the same side of the shoe; ;
  • two rotating elements placed at the rear of the shoe, each being integral in rotation with one of the longitudinal axes and being pivotable between two limit positions corresponding for one to the horizontal running position of the wheels and for the other at the vertical rolling position of the rollers;
  • an angular locking device of the rotating elements, which when unlocked releases the rotating elements and allows their free rotation under the effect of the weight or a force exerted on the rollers, the longitudinal axes or the rotating elements, and which when locked simultaneously blocks the rotating elements in one of their limit positions.

Une chaussure polyvalente 1 selon l'invention va maintenant être décrite de façon détaillée en référence aux figures.A versatile shoe 1 according to the invention will now be described in detail with reference to the figures.

La chaussure 1 comporte une semelle 2 dans le bord extérieur de laquelle sont ménagés des logements 3, 4, 5 et 6, destinés à recevoir chacun une roulette 7, 8, 9 ou 10. L'exemple représenté sur les figures concerne une chaussure équipée de quatre roulettes, dont deux référencées 7 et 8 sont placées du côté intérieur 13 de la chaussure 1 et deux roulettes 9 et 10 sont placées du côté extérieur 14 de la chaussure 1. Mais d'autres variantes concernant le nombre ou la disposition des roulettes sont possibles. On peut imaginer par exemple une chaussure avec une roulette intérieure et deux roulettes extérieures, ou l'inverse.The shoe 1 comprises a sole 2 in the outer edge of which are formed housing 3, 4, 5 and 6, each for receiving a wheel 7, 8, 9 or 10. The example shown in the figures relates to a fitted shoe four casters, two of which referenced 7 and 8 are placed on the inner side 13 of the shoe 1 and two casters 9 and 10 are placed on the outer side 14 of the boot 1. But other variations on the number or disposition of the casters are possible. One can imagine for example a shoe with an inner roller and two outer wheels, or vice versa.

Selon l'invention, des axes longitudinaux 15 et 16, placés un de chaque côté de la chaussure et de préférence en haut ou au-dessus de la semelle 2, supportent les roulettes situées du même côté, c'est-à-dire respectivement 7, 8 pour l'axe 15 et 9, 10 pour l'axe 16 sur l'exemple représenté, par l'intermédiaire de leur moyeu respectif 21, 23, 25 et 26.According to the invention, longitudinal axes 15 and 16, placed one on each side of the boot and preferably above or above the sole 2, support the rollers located on the same side, that is to say respectively 7, 8 for the axis 15 and 9, 10 for the axis 16 in the example shown, through their respective hubs 21, 23, 25 and 26.

Les axes 15 et 16 se présentent sous la forme de barres dont l'orientation générale est longitudinale par rapport à la chaussure et de préférence globalement parallèle aux bords extérieur et intérieur de la chaussure 1.The axes 15 and 16 are in the form of bars whose general orientation is longitudinal with respect to the boot and preferably generally parallel to the outer and inner edges of the boot 1.

Les axes longitudinaux 15 et 16 peuvent pivoter sur eux-mêmes et entraînent avec eux la rotation des roulettes qu'ils supportent. La liaison en rotation entre les moyeux 21, 23, 25, 26 et les axes 15, 16 est faite par des cannelures, des stries, des clavettes ou tout autre moyen connu.The longitudinal axes 15 and 16 can pivot on themselves and drive with them the rotation of the wheels that they support. The connection in rotation between the hubs 21, 23, 25, 26 and the axes 15, 16 is made by grooves, striations, keys or any other known means.

Les axes 15 et 16 sont guidés en rotation à l'arrière 12 par des paliers 18 et 20 qui sont de préférence reliés à une platine arrière 60 solidaire de la semelle 2. Cette platine arrière 60 peut être rapportée sur la semelle 2 ou être directement intégrée à celle-ci. Elle comprend une aile sensiblement verticale 27 disposée au niveau du chant arrière de la semelle 2 et de préférence une aile sensiblement horizontale 43 disposée sous la semelle 2 dans sa partie arrière.The axes 15 and 16 are guided in rotation at the rear 12 by bearings 18 and 20 which are preferably connected to a rear plate 60 integral with the sole 2. This rear plate 60 can be attached to the sole 2 or be directly integrated into it. It comprises a substantially vertical wing 27 disposed at the rear edge of the sole 2 and preferably a substantially horizontal wing 43 disposed under the sole 2 in its rear portion.

Les axes 15 et 16 sont guidés à l'avant 11 par des paliers 17 et 19, de préférence également reliés à une platine 28 solidaire de la semelle 2 et disposée sous la semelle 2 dans sa partie avant.The axes 15 and 16 are guided at the front 11 by bearings 17 and 19, preferably also connected to a plate 28 integral with the sole 2 and disposed under the sole 2 in its front portion.

Les paliers 17, 18, 19 et 20 comportent de préférence chacun une rotule de façon à permettre le débattement angulaire des axes 15 et 16 par rapport aux paliers respectivement 17, 18 et 19, 20. Ces rotules peuvent être remplacées par des liaisons souples entre les paliers 17, 19 et la platine 28 et entre les paliers 18, 20 et la platine 60. Ce débattement angulaire des axes 15, 16 apporte avantageusement une grande flexibilité à la semelle et autorise sa libre déformation lors de la marche, sans exercer de contraintes sur les axes et leurs paliers.The bearings 17, 18, 19 and 20 preferably each comprise a ball joint so as to allow the angular displacement of the pins 15 and 16 relative to the bearings 17, 18 and 19, respectively. These ball joints can be replaced by flexible links between the bearings 17, 19 and the plate 28 and between the bearings 18, 20 and the plate 60. This angular movement of the axes 15, 16 advantageously provides great flexibility to the sole and allows it to free deformed when walking, without exercising constraints on the axes and their bearings.

Ainsi la rotation des axes 15 et 16 fait basculer simultanément les roulettes qui leur sont solidaires, et les paliers à rotules 17, 18, 19, 20 garantissent un bon fonctionnement quelle que soit la déformation de la semelle 2.Thus the rotation of the axes 15 and 16 simultaneously tilts the casters which are integral therewith, and the ball bearings 17, 18, 19, 20 guarantee a good operation regardless of the deformation of the sole 2.

Etant donné que la chaussure est classiquement plus large à l'avant qu'à l'arrière, les axes 15 et 16 sont généralement plus écartés à l'avant qu'à l'arrière, comme le montre la figure 3. De ce fait les liaisons entre les jantes 22 et les moyeux 21, 23, 25, 26 sont réalisées de manière que les roulettes soient parallèles entre elles, et parallèles à la direction avant/arrière 11-12 lorsqu'elles sont en position verticale de roulage. Pour compenser cet écart de parallélisme entre les roulettes 7, 8 et 9, 10 et les axes 15 et 16, les logements des roulettes ont de préférence un fond 59 incliné par rapport au sol 41 et à la semelle 2.Since the boot is conventionally wider at the front than at the rear, the shafts 15 and 16 are generally wider at the front than at the rear, as shown in FIG. figure 3 . As a result, the connections between the rims 22 and the hubs 21, 23, 25, 26 are made in such a way that the rollers are parallel to each other and parallel to the front-rear direction 11-12 when they are in a vertical position. rolling. To compensate for this difference in parallelism between the rollers 7, 8 and 9, 10 and the axes 15 and 16, the caster housings preferably have a bottom 59 inclined relative to the ground 41 and to the sole 2.

La platine 60 est réalisée de préférence d'une seule pièce. La platine 28 peut également être d'un seul tenant ou être constituée de deux éléments indépendants droit et gauche, fixés séparément sur la semelle.The plate 60 is preferably made in one piece. The plate 28 may also be integral or consist of two independent elements right and left, separately attached to the sole.

Les platines 60 et 28 sont réalisées par exemple en tôle emboutie, en métal moulé ou en matière plastique injectée, et surmoulées lors de la réalisation de la semelle 2. Elles peuvent aussi être intégrées à la semelle 2, c'est-à-dire, moulées d'un seul tenant avec la semelle dans une matière plastique adaptée.The plates 60 and 28 are made for example of pressed sheet metal, molded metal or injected plastic, and overmolded during the production of the sole 2. They can also be integrated with the sole 2, that is to say , molded in one piece with the sole in a suitable plastic material.

Les figures 1 et 2 montrent la partie sensiblement verticale appelée aile 27 de la platine arrière 60. Cette partie verticale est située dans une zone de la chaussure 1 qui est protégée des chocs et du contact avec le sol 41. Elle peut avantageusement servir de support au dispositif de blocage angulaire des ensembles tournants.The figures 1 and 2 show the substantially vertical portion called wing 27 of the rear plate 60. This vertical part is located in an area of the boot 1 which is protected from shocks and the contact with the ground 41. It can advantageously serve as a support for the angular locking device rotating sets.

Des éléments tournants 30 et 31 sont solidaires en rotation respectivement des axes 15 et 16. La liaison en rotation peut être réalisée par tout moyen connu, tel que stries, cannelures, clavettes, goupilles, etc. Selon la première variante de l'invention, chaque élément tournant 30 ou 31 est de forme sensiblement allongée. Il est dirigé vers le haut lorsque les roulettes 7, 8, 9, 10 sont en position horizontale de marche comme le montre la figure 1. Il est situé sensiblement à l'horizontale lorsque les roulettes sont en position verticale de roulage (figure 2). Dans cette position horizontale, chaque élément tournant 30, 31 vient en butée contre un élément de butée 34 préférentiellement solidaire de l'aile 27.Rotating elements 30 and 31 are integral in rotation respectively with the axes 15 and 16. The rotational connection can be made by any known means, such as streaks, splines, keys, pins, etc. According to the first variant of the invention, each rotating element 30 or 31 is of substantially elongate shape. It is directed upwards when the rollers 7, 8, 9, 10 are in a horizontal position as shown in FIG. figure 1 . It is located substantially horizontally when the rollers are in a vertical rolling position ( figure 2 ). In this horizontal position, each rotating element 30, 31 abuts against an abutment element 34 preferably integral with the wing 27.

La figure 4 montre une première variante préférentielle du dispositif de blocage angulaire, avec du côté intérieur 13 la position de roulage, et du côté extérieur 14 la position de marche. Un verrou 33 est articulé à sa base, par l'intermédiaire d'un moyeu 53 qui lui est solidaire, autour d'un axe 54 lié à la platine 60. Le verrou 33 est plaqué contre l'aile 27 par un ressort 36 non représenté sur cette vue. Le verrou 33 comporte de chaque côté une surface latérale d'appui, respectivement 56 et 44, sensiblement verticale venant s'appuyer contre l'un des éléments tournants 31 ou 30. Le verrou 33 comporte également de chaque côté une surface inférieure d'appui, respectivement 55 et 58, destinée à bloquer chacun des éléments tournants 31, 30 en position horizontale.The figure 4 shows a first preferred variant of the angular locking device, with the inner side 13 the rolling position, and the outer side 14 the running position. A latch 33 is articulated at its base, via a hub 53 which is secured thereto, about an axis 54 connected to the plate 60. The latch 33 is pressed against the flange 27 by a spring 36. represented on this view. The lock 33 comprises on each side a lateral bearing surface, respectively 56 and 44, substantially vertical coming to bear against one of the rotating elements 31 or 30. The latch 33 also comprises on each side a lower bearing surface , respectively 55 and 58, for blocking each of the rotating elements 31, 30 in horizontal position.

D'autres positions angulaires des éléments tournants 30, 31 sont possibles selon l'invention, pourvu que l'écart entre la position de marche et celle de roulage soit sensiblement égal à 90 °.Other angular positions of the rotating elements 30, 31 are possible according to the invention, provided that the difference between the running position and that of rolling is substantially equal to 90 °.

Selon une réalisation préférée de l'invention, les surfaces d'appui 56, 55, 44 et 58 du verrou 33 et les bords correspondants des éléments tournants 30, 31 peuvent comporter des chanfreins ou des rayons destinés à faciliter l'engagement du verrou 33 dans chacune des positions et à supprimer les jeux.According to a preferred embodiment of the invention, the bearing surfaces 56, 55, 44 and 58 of the lock 33 and the corresponding edges of the rotating elements 30, 31 may comprise chamfers or spokes intended to facilitate the engagement of the lock 33 in each of the positions and to delete the games.

La figure 3 montre que selon une variante préférentielle de l'invention les roulettes avant 7 et 10 sont situées au moins partiellement à l'arrière de la ligne 40 qui est la ligne de flexion de la semelle 2. Lors de la marche, la semelle reste sensiblement plane à l'arrière de cette ligne, alors que la partie de la semelle située à l'avant de cette ligne 40 subit une flexion importante.The figure 3 shows that according to a preferred embodiment of the invention the front rollers 7 and 10 are located at least partially at the rear of the line 40 which is the bending line of the sole 2. When walking, the sole remains substantially flat at the rear of this line, while the part of the sole located at the front of this line 40 undergoes significant bending.

Les roulettes 7 et 10 situées sous la partie avant de la semelle 2 seront légèrement écartées l'une de l'autre, pour pouvoir laisser dans la semelle 2 une zone centrale 32 intacte, entre les logements 3, 5 destinés aux roulettes avant 7, 10, qui relie la zone déformable de la semelle 2 située à l'avant de la ligne de flexion 40 de la chaussure 1 à la zone arrière de la semelle 2, pouvant être plus rigide, située à l'arrière de cette ligne de flexion 40. Cette zone 32 est destinée à conférer à la semelle 2 un comportement homogène en flexion, et à compenser l'affaiblissement provoqué par les logements 3 et 5 des roulettes 7 et 10. Cette zone centrale 32 supportera également une partie du poids de l'utilisateur, lors de la marche.The rollers 7 and 10 located under the front part of the sole 2 will be slightly spaced from each other, to be able to leave in the sole 2 an intact central zone 32, between the housings 3, 5 intended for the front rollers 7, 10, which connects the deformable zone of the sole 2 located at the front of the bending line 40 of the shoe 1 to the rear zone of the sole 2, which may be more rigid, located at the rear of this flexion line 40. This zone 32 is intended to give the sole 2 a homogeneous bending behavior, and to compensate for the weakening caused by the housings 3 and 5 of the rollers 7 and 10. This central zone 32 will also support a portion of the weight of the user, when walking.

Pour permettre l'utilisation de roulettes de grand diamètre, il est possible de les superposer partiellement. Cette disposition peut être avantageuse pour les roulettes arrière 8, 9 situées sous le talon qui est plus étroit que l'avant de la semelle. Ainsi, au moins deux des roulettes pourront être placées partiellement l'une au-dessus de l'autre en position horizontale de marche.To allow the use of large diameter wheels, it is possible to superimpose them partially. This arrangement may be advantageous for the rear wheels 8, 9 located under the heel which is narrower than the front of the sole. Thus, at least two of the casters can be placed partially one above the other in horizontal walking position.

La figure 5 représente une coupe au travers de la roulette 7 en position horizontale de marche. Les roulettes 7, 8, 9, 10 ont de préférence une jante 22 creuse. Selon un mode de réalisation préférentiel de l'invention, un élément de semelle 39 solidaire de la semelle 2 et de préférence sensiblement cylindrique, peut avantageusement traverser la jante 22 de la roulette 7 et prendre appui sur le sol 41 lorsque les roulettes sont en position horizontale de marche.The figure 5 represents a section through the wheel 7 in the horizontal position. The rollers 7, 8, 9, 10 preferably have a hollow rim 22. According to a preferred embodiment of the invention, a sole member 39 integral with the sole 2 and preferably substantially cylindrical, may advantageously pass through the rim 22 of the wheel 7 and bear on the ground 41 when the wheels are in position horizontal walk.

De cette manière la présence des roulettes ne réduit que faiblement la surface de contact de la semelle avec le sol.In this way the presence of the rollers reduces only slightly the contact surface of the sole with the ground.

Chaque roulette comporte de préférence une bande de roulement 42 ainsi qu'une joue 38 dirigée vers le sol et destinée à protéger la roulette. Ces éléments 42 et 38 sont par exemple réalisés dans un matériau élastique du type caoutchouc ou polyuréthane.Each wheel preferably comprises a tread 42 and a cheek 38 directed towards the ground and intended to protect the wheel. These elements 42 and 38 are for example made of an elastic material of the rubber or polyurethane type.

Chaque jante 22 est solidaire du moyeu 21, 23, 25 ou 26 de la roulette concernée. Sur la figure 5, la jante 22 est reliée solidairement au moyeu 21.Each rim 22 is secured to the hub 21, 23, 25 or 26 of the wheel concerned. On the figure 5 , the rim 22 is integrally connected to the hub 21.

De préférence, la joue 38 de chaque roulette est surélevée par rapport au sol lorsque les roulettes sont en position horizontale de marche. Ainsi les roulettes et le mécanisme qui les supporte ne subissent pas d'efforts lors de la marche normale mais uniquement des efforts occasionnels par exemple sur un sol sablonneux.Preferably, the cheek 38 of each wheel is elevated relative to the ground when the rollers are in a horizontal position. Thus the casters and the mechanism that supports them do not undergo efforts during normal walking but only occasional efforts for example on sandy soil.

La figure 6 montre une deuxième variante du dispositif de blocage angulaire des éléments tournants 30, 31. Le verrou 33 est poussé en direction de l'aile 27 de la platine 60 par le ressort 36. Selon l'invention, le verrou 33 comporte une lame ressort 24 qui lui est solidaire. Cette lame ressort 24 a une position libre 24' représentée en pointillés. Sous l'action du ressort 36, la lame ressort 24 est comprimée et son extrémité 37 pousse l'élément tournant 30 en position verticale. La position de l'extrémité 37 de la lame ressort 24 est définie de façon que la roulette 7 soit plaquée sous contrainte contre le fond 59 du logement de la semelle 2. De cette manière, grâce à la poussée élastique de la lame ressort 24, les jeux sont éliminés et les roulettes 7, 8, 9, 10 sont plaquées élastiquement contre le fond de leur logement respectif en position horizontale de marche, ce qui évite les bruits et les claquements pendant la marche ou la course.The figure 6 shows a second variant of the angular locking device of the rotating elements 30, 31. The latch 33 is pushed towards the flange 27 of the plate 60 by the spring 36. According to the invention, the latch 33 comprises a spring blade 24 who is in solidarity with him. This leaf spring 24 has a free position 24 'shown in dashed lines. Under the action of the spring 36, the spring blade 24 is compressed and its end 37 pushes the rotating member 30 in a vertical position. The position of the end 37 of the leaf spring 24 is defined so that the wheel 7 is pressed against the bottom 59 of the housing of the sole 2. In this way, thanks to the elastic thrust of the leaf spring 24, the games are eliminated and the casters 7, 8, 9, 10 are elastically pressed against the bottom of their respective housing in a horizontal position, which avoids noises and clicks during walking or running.

Avantageusement, une enveloppe souple non représentée peut recouvrir le dispositif de blocage angulaire comprenant dans ce cas le verrou 33 ainsi que son articulation par moyeu 53 et axe 54 et son ressort 36. Elle peut recouvrir également un ou plusieurs autres éléments tels que la platine 60, les éléments tournants 30, 31, les axes longitudinaux 15, 16 et/ou les paliers 17, 18, 19, 20. Cette enveloppe permet les déplacements des éléments mobiles et du verrou 33, mais protège l'ensemble contre les salissures et les chocs.Advantageously, a flexible envelope (not shown) can cover the angular locking device comprising in this case the lock 33 as well as its hinge 53 and hub 54 and its spring 36. It can also cover one or more other elements such as the plate 60 , the rotating elements 30, 31, the longitudinal axes 15, 16 and / or the bearings 17, 18, 19, 20. This envelope allows movement of the movable elements and the lock 33, but protects the assembly against dirt and grease. shocks.

L'ensemble des caractéristiques qui viennent d'être décrites permet à la semelle équipée de se déformer librement en flexion et en torsion lors de la marche sans que ces déformations n'entraînent des contraintes sur les composants mécaniques. D'autre part, les composants mécaniques tels que les axes 15, 16, les paliers 17, 18, 19, 20, les éléments tournants 30, 31, 45, 49 et le dispositif de blocage angulaire 33, 47, 50, 52 sont placés au-dessus des roulettes 7, 8, 9, 10 et en haut de la semelle 2, et les roulettes ne touchent pas le sol 41 en condition normale. Ainsi il n'y a pas de risque d'usure ou de salissure.All the characteristics that have just been described allows the sole equipped to deform freely in flexion and torsion during walking without these deformations cause constraints on the mechanical components. On the other hand, the mechanical components such as the axes 15, 16, the bearings 17, 18, 19, 20, the rotating elements 30, 31, 45, 49 and the angular locking device 33, 47, 50, 52 are placed above the wheels 7, 8, 9, 10 and at the top of the sole 2, and the wheels do not touch the ground 41 in normal condition. Thus there is no risk of wear or dirt.

Ces caractéristiques constituent une amélioration significative par rapport à l'art antérieur.These features are a significant improvement over art prior.

La figure 5 montre que le centre de gravité de la roulette 7 est décalé par rapport à l'axe longitudinal 15. Ainsi, selon l'invention, lorsque le dispositif de blocage angulaire a été déverrouillé, par exemple par action sur le verrou 33 qui libère les éléments tournants 30 et 31, les axes longitudinaux 15 et 16 sont entraînés en rotation par le poids désaxé des roulettes 7, 8, 9, 10. Un tel pivotement pourrait également être causé par un élément élastique agissant sur les éléments tournants, les axes longitudinaux ou les roulettes. Les roulettes 7, 8 ,9 et 10 se retrouvent alors, par gravité ou effet élastique, dans une position intermédiaire. L'angle d'inclinaison des roulettes dans cette position intermédiaire, est compris entre la verticale et l'horizontale.The figure 5 shows that the center of gravity of the wheel 7 is offset with respect to the longitudinal axis 15. Thus, according to the invention, when the angular locking device has been unlocked, for example by action on the lock 33 which releases the elements 30 and 31, the longitudinal axes 15 and 16 are rotated by the off-axis weight of the rollers 7, 8, 9, 10. Such a pivoting could also be caused by an elastic element acting on the rotating elements, the longitudinal axes or the wheels. Casters 7, 8, 9 and 10 are then found, by gravity or elastic effect, in an intermediate position. The angle of inclination of the rollers in this intermediate position is between the vertical and the horizontal.

Dans cette position intermédiaire, une poussée verticale de la chaussure 1 sur les roulettes 7, 8, 9, 10 entraînera un placage de celles-ci sous la semelle 2 en position horizontale de marche, puis un verrouillage automatique du dispositif de blocage angulaire sous l'action du ressort 36 et du verrou 33. Inversement, un frottement latéral d'une roulette 7, 8, 9 ou 10 vers l'extérieur de la chaussure entraînera une rotation de l'ensemble tournant correspondant en position verticale de roulage puis un verrouillage automatique du dispositif de blocage angulaire dans cette position.In this intermediate position, a vertical thrust of the boot 1 on the rollers 7, 8, 9, 10 will cause a plating thereof under the sole 2 in the horizontal operating position, then an automatic locking of the angular locking device under the action of the spring 36 and the latch 33. Conversely, a lateral friction of a wheel 7, 8, 9 or 10 towards the outside of the shoe will cause a rotation of the corresponding rotating assembly in the vertical rolling position and a lock automatic locking device in this position.

Dans le cas où on voudrait obtenir une inclinaison des roulettes, différente de celle qui est obtenue par simple gravité, il est possible de placer des ressorts par exemple entre les axes longitudinaux 15, 16 et les platines fixes. Ces ressorts entraîneront les ensembles tournants dans leur position d'équilibre correspondant à la position angulaire souhaitée.In the case where one would like to obtain an inclination of the wheels, different from that obtained by simple gravity, it is possible to place springs for example between the longitudinal axes 15, 16 and the fixed plates. These springs will cause the rotating assemblies in their equilibrium position corresponding to the desired angular position.

La figure 7 montre une troisième variante du dispositif de blocage angulaire des éléments tournants, vue de l'arrière. Du côté gauche on a représenté le dispositif bloquant les roulettes 9, 10 en position horizontale. Côté droit, le dispositif bloque les roulettes 7, 8 en position verticale. Chaque élément tournant 45 a sensiblement la forme d'un quart de disque centré sur l'axe longitudinal 15 ou 16 correspondant et solidaire de celui-ci. Un ressort 47, préférentiellement double et symétrique, solidaire de l'aile 27 de la platine 60 vient en butée sur des surfaces radiales de l'élément tournant 45 pour bloquer la rotation. L'élément tournant 45 est limité en rotation dans l'autre sens par un pion 46 solidaire de l'aile 27. Ainsi il suffit d'appuyer vers le bas sur le ressort 47, plus précisément sur ses deux branches symétriques, pour libérer la rotation des ensembles tournants et faire pivoter les roulettes 7, 8, 9 et 10 en position intermédiaire.The figure 7 shows a third variant of the angular locking device of the rotating elements, seen from the rear. On the left side there is shown the device blocking the rollers 9, 10 in the horizontal position. Right side, the device locks the casters 7, 8 in the vertical position. Each rotating element 45 has substantially the shape of a quarter disc centered on the longitudinal axis 15 or 16 corresponding and integral thereof. A spring 47, preferably double and symmetrical, integral with the flange 27 of the plate 60 abuts radial surfaces of the rotating member 45 to block the rotation. The rotating element 45 is limited in rotation in the other direction by a pin 46 secured to the flange 27. Thus it is sufficient to press down on the spring 47, more precisely on its two symmetrical branches, to release the rotation of the rotating assemblies and rotate the rollers 7, 8, 9 and 10 in the intermediate position.

Cet appui peut être effectué au moyen de plusieurs tiges ou câbles tels que 48, actionnés de préférence par un bouton commun afin d'agir simultanément sur chacun des ressorts 47.This support can be performed by means of several rods or cables such as 48, preferably actuated by a common button to act simultaneously on each of the springs 47.

D'une manière générale et quelle que soit la nature du dispositif de blocage angulaire, la chaussure polyvalente selon l'invention comporte de préférence un levier ou un bouton d'actionnement unique qui permet de déverrouiller le dispositif de blocage angulaire.In general, and regardless of the nature of the angular locking device, the multipurpose shoe according to the invention preferably comprises a lever or a single actuating button which allows to unlock the angular locking device.

Ce levier ou ce bouton d'actionnement peut être actionné manuellement, en tapant par exemple contre un trottoir ou préférentiellement en appuyant sur une zone spécialement aménagée de l'autre chaussure.This lever or this actuation button can be operated manually, by typing for example against a sidewalk or preferably by pressing a specially equipped area of the other shoe.

Le cas échéant le ressort double et symétrique 47 pourra être remplacé par des leviers articulés au centre de l'aile 27 et poussés contre les éléments tournants 45 par des ressorts.If necessary, the double and symmetrical spring 47 can be replaced by levers articulated in the center of the wing 27 and pushed against the rotating elements 45 by springs.

La figure 8 montre deux autres solutions techniques permettant de réaliser un dispositif de blocage angulaire des éléments tournants :

  • Côté gauche, selon une quatrième variante de l'invention, l'élément tournant 31 a une forme sensiblement allongée. Il est bloqué en position par un disque 52 guidé en translation dans l'aile 27 de la platine 60 au moyen d'un élément de guidage 51 visible sur la figure 9.
The figure 8 shows two other technical solutions for producing an angular locking device of the rotating elements:
  • Left side, according to a fourth variant of the invention, the rotating member 31 has a substantially elongate shape. It is locked in position by a disc 52 guided in translation in the flange 27 of the plate 60 by means of a guide element 51 visible on the figure 9 .

En faisant coulisser le disque 52 vers le haut, on libère la rotation de l'élément tournant. Un ressort non représenté pousse automatiquement le disque 52 en position de verrouillage. Le disque de blocage 52 peut avoir un chant chanfreiné permettant de faciliter l'engagement ou de forme sensiblement conique dans le but d'éliminer les jeux entre les roulettes et le fond 59 des logements de la semelle.

  • Côté droit, la figure 8 montre une cinquième variante de l'invention dans laquelle l'élément tournant 49 a sensiblement la forme d'un quart de disque. Un élément de blocage 50, guidé en translation horizontale sur l'aile 27 de la platine 60, est poussé par un ressort contre l'élément tournant 49.
By sliding the disk 52 upwards, the rotation of the rotating element is released. A not shown spring automatically pushes the disc 52 to the locked position. The locking disk 52 may have a chamfered edge to facilitate engagement or substantially conical shape in order to eliminate the clearance between the wheels and the bottom 59 of the housing of the sole.
  • Right side, the figure 8 shows a fifth variant of the invention in which the rotating element 49 has substantially the shape of a quarter disc. A locking element 50, guided in horizontal translation on the flange 27 of the plate 60, is pushed by a spring against the rotating element 49.

En faisant coulisser horizontalement les éléments de blocage 50 droit et gauche vers le milieu de l'aile 27, on libère la rotation de chaque ensemble tournant. Les éléments tournants 49 possèdent chacun un ergot 57 qui limite la rotation des ensembles tournants dès que la position verticale des roulettes 7, 8, 9, 10 est atteinte, en venant en appui contre l'élément de blocage 50 correspondant.By sliding the right and left blocking elements 50 horizontally towards the middle of the wing 27, the rotation of each rotary assembly is released. The rotating elements 49 each have a lug 57 which limits the rotation of the rotating assemblies as soon as the vertical position of the rollers 7, 8, 9, 10 is reached, bearing against the corresponding blocking element 50.

Sur la figure 3, les axes longitudinaux 15 et 16 sont représentés droits. Selon une variante de l'invention, la partie centrale de ces axes, située entre les paliers 17, 19 et les moyeux 23, 26, peut suivre la courbure de la semelle. De cette façon les axes 15 et 16 sont proches de la semelle 2 et peuvent être appuyés sous elle.On the figure 3 the longitudinal axes 15 and 16 are shown straight. According to a variant of the invention, the central portion of these axes, located between the bearings 17, 19 and the hubs 23, 26, can follow the curvature of the sole. In this way the axes 15 and 16 are close to the sole 2 and can be supported under it.

Il est possible également, pour améliorer la flexibilité de la semelle équipée, de placer des articulations telles que des cardans sur les axes 15 et 16, à proximité des paliers 17,19 et des moyeux 23,26.It is also possible, to improve the flexibility of the fitted sole, to place joints such as universal joints on the pins 15 and 16, near the bearings 17, 19 and the hubs 23, 26.

Pour améliorer la sécurité, on peut rajouter un verrouillage supplémentaire qui bloque les roulettes 7, 8, 9, 10 en position horizontale de marche. Ce verrouillage peut être constitué de verrous, actionnés simultanément par le verrou 33 ou par un levier séparé, et qui agissent par exemple directement sur les jantes 22.To improve safety, we can add an additional lock that locks the casters 7, 8, 9, 10 in the horizontal position. This locking can consist of locks, actuated simultaneously by the lock 33 or by a separate lever, and which act for example directly on the rims 22.

Les figures 10 et 11 illustrent une variante à roulettes orientables par couples en virage. Le but est d'obtenir des lignes d'essieu géométrique se mettant en oblique et si possible au moins pour l'un d'entre eux et notamment l'essieu géométrique avant d'être rayonnant ou approximativement rayonnant, c'est-à-dire dans la prolongation ou approximativement dans la prolongation d'un rayon du cercle de virage ou du cercle moyen de virage.The figures 10 and 11 illustrate a variant with rotating castors in pairs when turning. The aim is to obtain oblique geometric axle lines and if possible at least for one of them and in particular the geometric axle before being radiating or approximately radiating, that is to say say in the extension or approximately in the extension of a radius of the turn circle or the average circle of turn.

Les roulettes sont ainsi orientées de façon correcte pendant le virage. On limite de cette façon l'usure et on améliore dans les courbes l'équilibre de celui qui porte les chaussures.The wheels are thus oriented correctly during the turn. In this way wear is limited and the balance of the wearer is improved in the curves.

Dans la variante représentée sur les figures 10 et 11, l'inclinaison de la semelle 2 provoque l'orientation correcte des deux couples de roulettes couple par couple et à toute variation d'inclinaison correspond une variation d'orientation des couples de roulettes ou au moins d'un couple de roulettes. Le roulage en courbe devient ainsi plus confortable et plus sûr.In the variant shown on the figures 10 and 11 , the inclination of the sole 2 causes the correct orientation of the two pairs of pairs of casters torque and any variation in inclination corresponds to a variation of orientation pairs of casters or at least a pair of casters. The curving becomes more comfortable and safer.

On peut rendre orientable qu'un seul couple de roulettes, de préférence le couple avant.We can make orientable only one pair of wheels, preferably the front couple.

Pour ce faire, on rajoute un dispositif permettant de faire pivoter les platines avant 28 et arrière 60 ou uniquement l'une d'entre elles. Ces platines devenant mobiles 28 et 60 ou l'une seule d'entre elles, sont ou est reliée(s) cinématiquement à la semelle 2 par un axe incliné à environ 45° respectivement vers l'avant pour l'axe incliné arrière 61 et vers l'arrière pour l'axe incliné avant 62. La liaison est purement fonctionnelle. Il peut s'agir d'une simple poussée. Ces axes sont portés respectivement par une platine fixe arrière 63 et par une platine fixe avant 64. Ces axes inclinés sont situés dans le plan médian de la semelle 2 comme visible sur les figures 10 et 11.To do this, we add a device for pivoting the front plates 28 and rear 60 or only one of them. These plates becoming mobile 28 and 60 or only one of them, are or is connected (s) kinematically to the sole 2 by an axis inclined at approximately 45 ° respectively forward for the rear inclined axis 61 and towards the rear for the inclined axis before 62. The connection is purely functional. It can be a simple push. These axes are carried respectively by a fixed rear plate 63 and a fixed front plate 64. These inclined axes are located in the median plane of the sole 2 as visible on the figures 10 and 11 .

Les axes inclinés 61 et 62 portent chacun en extrémité une pièce palière 65 et 66 agissant en tournant sur elle-même et en étant en contact avec la platine pivotante correspondante pour la faire pivoter dans le sens voulu c'est-à-dire celui déterminé par l'inclinaison de la semelle 2, ce qui entraîne pour chaque axe incliné le pivotement simultané des deux roulettes d'un même couple de roulettes.The inclined axes 61 and 62 each carry at the end a bearing member 65 and 66 acting by rotating on itself and being in contact with the corresponding pivoting plate to rotate in the desired direction that is to say that determined by the inclination of the sole 2, resulting for each inclined axis simultaneous pivoting of the two wheels of the same pair of wheels.

Ainsi, lorsque l'on incline le pied et donc la semelle 2, chaque platine est entraînée en mouvement par exemple par pivotement autour de son axe propre par l'effet de la pièce palière de l'axe incliné correspondant.Thus, when one inclines the foot and thus the sole 2, each plate is driven in motion for example by pivoting about its own axis by the effect of the piece of land of the corresponding inclined axis.

Les platines pivotantes 28 et 60 ne sont alors plus parallèles entre elles mais leurs bords avant et arrière sont dirigés vers le centre du virage et la chaussure inclinée vers la droite ou la gauche décrira automatiquement un virage dans le même sens.The turntables 28 and 60 are then no longer parallel to each other but their front and rear edges are directed towards the center of the turn and the shoe inclined to the right or left will automatically describe a turn in the same direction.

En raison de l'orientation des roulettes d'un même couple de roulettes à la manière d'un essieu pivotant pour chaque couple de roulettes, les distances entre les roulettes avant et arrière deviennent variables et il y a lieu de prévoir une liberté de mouvement par des axes longitudinaux 15 et 16 de longueur variable par exemple extensibles. On peut citer à titre d'exemple, un système de cannelures assurant une rigidité en torsion tout en permettant aux paliers des roulettes sur une même ligne de roulage de se rapprocher ou de s'éloigner.Due to the orientation of the casters of the same pair of casters in the manner of a pivoting axle for each pair of casters, the distances between the front and rear casters become variable and it is necessary to provide a freedom of movement by longitudinal axes 15 and 16 of variable length for example extensible. By way of example, a system of grooves can be cited which provides torsional stiffness while allowing the bearings of the rollers on the same rolling line to move closer or further away.

De plus, pour autoriser les débattements angulaires provoqués par le pivotement des platines arrière 60 et avant 28, les extrémités des axes 15 et 16 sont articulés, de préférence par une articulation multidirectionnelle.In addition, to allow angular deflections caused by the pivoting of the rear plates 60 and before 28, the ends of the axes 15 and 16 are articulated, preferably by a multidirectional hinge.

Un exemple d'axes extensibles est illustré par la figure 10 sur laquelle on peut voir des axes 15 et 16 télescopiques réalisés en deux parties 67, 68 et 69, 70 et à leurs extrémités des liaisons articulées du type à la cardan 71, 72 à l'arrière et 73, 74 à l'avant.An example of extensible axes is illustrated by the figure 10 on which can be seen 15 and 16 telescopic shafts made in two parts 67, 68 and 69, 70 and at their ends articulated joints of the cardan type 71, 72 at the rear and 73, 74 at the front.

Ces débattements angulaires pouvant être limités, on peut envisager sur le plan technologique un équivalent de cardan par déformation élastique de deux pièces ou par déformation d'intermédiaires ou d'intercalaires apportant une liaison souple.As these angular deflections may be limited, it is possible to envisage, from a technological point of view, a gimbal equivalent by elastic deformation of two parts or by deformation of intermediates or inserts providing a flexible connection.

De manière évidente, l'invention ne se limite pas aux modes de réalisation préférentiels décrits précédemment et représentés sur les différentes figures, l'homme du métier pouvant y apporter de nombreuses modifications et imaginer d'autres variantes sans sortir ni de la portée, ni du cadre de l'invention définis par les revendications.Obviously, the invention is not limited to the preferred embodiments described above and shown in the various figures, the skilled person can make many modifications and imagine other variants without departing from the scope and of the scope of the invention defined by the claims.
