Description

La présente invention a pour objet un patin à roulettes comprenant un châssis équipé de roulettes et une chaussure fixée amoviblement au châssis en quatre points non alignés, par accrochage et verrouillage de manière à assurer une liaison stable entre la chaussure et le châssis, le verrouillage étant assuré automatiquement par la déformation d'un organe élastique lors du chaussage du châssis à roulettes.The present invention relates to a roller skate comprising a chassis fitted with castors and a shoe removably attached to the chassis in four non-aligned points, by hooking and locking so as to ensure a stable connection between the shoe and the chassis, the locking being ensured automatically by deformation of an organ elastic when fitting the chassis on casters.

La fixation amovible d'une chaussure à un patin à glace ou à roulettes remonte à l'origine du patinage. La fixation se faisait généralement par des griffes actionnées par un levier et venant enserrer la semelle de la chaussure. De telles fixations sont décrites dans les brevets CH 118 742 et US 1 402 010.Removable attachment of a shoe to an ice skate or on wheels goes back to the origin of skating. The fixing was generally done by claws actuated by a lever and enclosing the sole of the shoe. Such attachments are described in the patents CH 118 742 and US 1 402 010.

Dans une version plus moderne, décrite dans le brevet US 3 918 729, la semelle de la chaussure est munie d'une plaque métallique présentant, à l'avant, deux trous en forme de trous de serrure venant s'accrocher sur deux tenons du patin et, à l'arrière, un trou de baïonnette dans lequel vient s'engager un organe rotatif muni d'un bras d'actionnement et de deux barrettes horizontales venant s'appuyer sur deux rampes de manière à plaquer le talon de la chaussure contre la plaque métallique du patin. Ce patin ne comporte pas de moyen de verrouillage, la fixation étant maintenue par frottement. In a more modern version, described in the patent US 3,918,729, the sole of the shoe is provided a metal plate with two front panels holes in the shape of keyholes coming to hang on two skate tenons and, at the back, a hole bayonet in which an organ engages rotary with one actuating arm and two horizontal bars coming to rest on two ramps so as to press the heel of the shoe against the metal plate of the skate. This skate has no locking means, the fixing being maintained by friction.

Du brevet US 5 507 506 qui correspond au préambule de la revendication 1, on connaít un patin à roulettes à chaussure amovible dans lequel la chaussure est munie de glissières à l'avant et à l'arrière, ces glissières venant s'engager sur des rails du châssis. Un verrouillage automatique est assuré par une lame-ressort coudée sur laquelle le talon de la chaussure vient s'accrocher. Une telle exécution présente toutefois plusieurs inconvénients : il n'est pas aisé d'engager les glissières de la chaussure sur les rails, d'autant plus qu'aucun jeu ne peut être toléré, ce qui exige une précision de fabrication ou un engagement à force peu acceptable ou encore une déformation élastique nuisant à la stabilité de la chaussure. L'absence de jeu longitudinal au niveau du verrouillage est également difficile à maítriser. La libération de la chaussure est peu commode.From US Patent 5,507,506 which corresponds to the preamble of claim 1, there is a roller skate with removable shoe in which the shoe is provided front and rear slides, these slides coming to engage on chassis rails. A automatic locking is ensured by a leaf spring bent on which the heel of the shoe just hang on. Such an execution presents however several drawbacks: it is not easy to engage the shoe slides on the rails, all the more that no play can be tolerated, which requires manufacturing accuracy or a commitment to unacceptable strength or deformation elastic detrimental to the stability of the shoe. The absence of longitudinal play at the locking level is also difficult to master. The release of the shoe is awkward.

De la demande de brevet FR 2 720 286, on connaít en outre un patin à roulettes à chaussure amovible dans lequel la chaussure est fixée par accrochage à l'avant, tandis qu'à l'arrière, la chaussure est munie d'un dispositif à genouillère par lequel on peut l'accrocher à l'arrière du châssis pour plaquer le talon de la chaussure contre le châssis.From patent application FR 2 720 286, we know in in addition to a removable shoe roller skate in which the shoe is fixed by hooking at the front, while at the back, the shoe is provided with a toggle device by which it can be hung at the back of the chassis to press the heel of the shoe against the chassis.

L'invention a pour but de réaliser une fixation automatique simple, robuste, très stable, exempte de jeu et facile à ouvrir pour libérer la chaussure.The object of the invention is to provide a fixing automatic simple, robust, very stable, free of playable and easy to open to release the shoe.

Le patin à roulettes selon l'invention est caractérisé en ce que l'accrochage et le verrouillage automatique sont assurés en tous les point de fixation par au moins un élément d'accrochage et de verrouillage soumis à l'action d'au moins d'un moyen élastique de rappel en position verrouillée et en ce que la patin comprend un moyen de déverrouillage constitué d'un levier de déverrouillage articulé à l'arrière du châssis et agissant sur l'élément d'accrochage et de verrouillage contre l'action du moyen élastique de manière à libérer la chaussure.The roller skate according to the invention is characterized in that hooking and automatic locking are secured at all fixing points by at least a hooking element and lock subject to the action of at least one means elastic return in the locked position and in this that the skate includes an unlocking means consisting of a release lever articulated at the back of the chassis and acting on the element hooking and locking against the action of the elastic means so as to release the shoe.

Selon certains modes d'exécution, l'accrochage et le verrouillage s'effectuent simultanément aux quatre points d'accrochage par un élément d'accrochage et de verrouillage commun aux quatre points.According to certain embodiments, the attachment and the locking takes place simultaneously with the four hooking points by a hooking element and locking common to the four points.

Le levier de déverrouillage agit, de préférence, directement sur l'élément d'accrochage et de verrouillage.The unlocking lever preferably acts directly on the attachment element and locking.

Le levier de déverrouillage est de préférence articulé à l'arrière du châssis autour d'un axe horizontal transversal au châssis. Selon un mode d'exécution, lorsque la chaussure est séparée du châssis, le levier est maintenu dans une position sensiblement verticale par l'élément d'accrochage et de verrouillage, de telle sorte qu'il est utilisable comme poignée lors du chaussage des roulettes.The unlocking lever is preferably articulated at the rear of the chassis around a horizontal axis transverse to the chassis. According to an embodiment, when the shoe is separated from the chassis, the lever is held in a substantially vertical position by the hooking and locking element, such so it can be used as a handle when fitting the wheels.

Avantageusement, le châssis présente, aux quatre points d'accrochage, des encoches en V dans lesquelles s'engagent des barrettes ou des tenons horizontaux de la chaussure. Advantageously, the chassis has, at the four points hooking, V-shaped notches in which engage horizontal bars or studs of the shoe.

Selon un mode d'exécution l'élément d'accrochage et de verrouillage, commun aux quatre points d'accrochage, présente des becs venant s'engager sur les barrettes ou tenons par des côtés inclinés de manière à les presser au fond des encoches en V. Ces côtés inclinés ont en outre pour effet de rattraper les jeux dus à l'usure des encoches et/ou des barrettes ou tenons.According to one embodiment, the attachment element and locking, common to the four attachment points, has beaks coming to engage on the bars or hold by inclined sides so as to press them at the bottom of the V-shaped notches. These inclined sides have additionally to make up for play due to wear notches and / or bars or tenons.

Une usure différente des deux côtés du châssis peut être rattrapée grâce à la réalisation de l'élément d'accrochage et de verrouillage sous la forme de deux plaques parallèles découpées reliées entre elles par une entretoise avec un jeu autorisant un déplacement longitudinal d'une plaque par rapport à l'autre.Different wear on both sides of the chassis may to be caught up with the achievement of the element hooking and locking in the form of two cut parallel plates connected together by a spacer with a clearance allowing displacement longitudinal of one plate relative to the other.

L'accrochage automatique peut être réalisé simplement en donnant une inclinaison aux côtés supérieurs inclinés des becs d'accrochage de manière à ce que les becs s'écartent sous la pression des barrettes ou tenons.Automatic snapping can be done simply tilting the upper sides inclined hooking spouts so that the beaks move apart under the pressure of the bars or tenons.

Ce mode d'exécution exige d'appuyer relativement fortement le pied sur le châssis pour le chaussage, pour vaincre la force du ressort de rappel. Selon un autre mode d'exécution, cette pression peut être fortement réduite en utilisant une gâchette retenant l'élément d'accrochage et de verrouillage en position déverrouillée, cette gâchette étant positionnée relativement au niveau du fond des encoches en V du châssis de manière à être actionnée par les tenons ou barrettes de la chaussure lors du chaussage. Cette gâchette peut être réalisée de différentes manières. This mode of execution requires relatively pressing strongly foot on the chassis for putting on, to overcome the force of the return spring. According to a other mode of execution, this pressure can be greatly reduced by using a retaining trigger the latching and locking element in position unlocked, this trigger being positioned relatively to the level of the bottom of the V-notches of the chassis so as to be actuated by tenons or bars of the shoe when putting on. This trigger can be achieved in different ways.

Avantageusement, un seul et même ressort assure à la fois le rappel de la gâchette et de l'élément d'accrochage et de verrouillage.Advantageously, a single spring ensures the times the trigger and element recall hooking and locking.

Le levier de déverrouillage peut en outre être utilisé comme poignée pour la manipulation du châssis lors du chaussage et comme moyen auxiliaire de maintien latéral de la chaussure, en particulier d'un collier équipant la chaussure.The release lever can also be used as a handle for handling the chassis during footwear and as an auxiliary lateral support the shoe, in particular a collar fitted the shoe.

    • Le patin complet représenté à la figure 1 comprend une chaussure 1 montée amoviblement sur un châssis 2 équipé de quatre roulettes en ligne 3.The complete skate shown in Figure 1 includes a shoe 1 removably mounted on a chassis 2 fitted of four rollers in line 3.

    Le châssis 2 présente deux plaques parallèles 2a et 2b entre lesquelles sont montées les roulettes 3. Ces plaques sont entretoisées. Un tel châssis peut être réalisé, par exemple, au moyen d'un profilé extrudé en aluminium. Les bords supérieurs des plaques 2a et 2b présentent quatre encoches 4, 5, 6, 7 en forme de V disposées par paires l'une en face de l'autre, comme représenté à la figure 2. L'encoche 7 se trouve dans l'alignement de l'encoche 5 à la figure 2. Le châssis comporte en outre un élément d'accrochage et de verrouillage 8 articulé en un point intermédiaire dans le châssis 2 autour d'un axe 9 transversal au châssis, et monté avec jeu, c'est-à-dire perpendiculaire aux plaques 2a et 2b. Dans l'exemple représenté, l'élément d'accrochage et de verrouillage 8, que nous appellerons par la suite le verrou par mesure de simplification, est constitué de deux plaques métalliques parallèles découpées 8a et 8b reliées par une entretoise 10 de manière à présenter une largeur hors tout sensiblement égale à l'espace séparant les plaques 2a et 2b du châssis. Cette distance est, de préférence, d'environ 30 mm. La liaison entre l'entretoise 10 et la plaque 8a et 8b présente un jeu, de telle sorte que les plaques peuvent se déplacer légèrement longitudinalement l'une par rapport à l'autre.The chassis 2 has two parallel plates 2a and 2b between which are mounted the rollers 3. These plates are braced. Such a chassis can be made, for example, by means of an extruded profile in aluminum. The upper edges of the plates 2a and 2b have four V-shaped notches 4, 5, 6, 7 arranged in pairs opposite one another, as shown in Figure 2. The notch 7 is located in the alignment of the notch 5 in figure 2. The chassis further includes a hooking and lock 8 articulated at an intermediate point in the chassis 2 around an axis 9 transverse to the chassis, and mounted with play, i.e. perpendicular to plates 2a and 2b. In the example shown, the element hooking and locking 8, which we will call thereafter the lock for simplification, consists of two parallel metal plates cutouts 8a and 8b connected by a spacer 10 of so as to present a substantially overall width equal to the space separating plates 2a and 2b from frame. This distance is preferably about 30 mm. The connection between the spacer 10 and the plate 8a and 8b presents a clearance, so that the plates can move slightly longitudinally one compared to each other.

    Le verrou 8 présente, à l'avant, une paire de becs 12 et, dans sa partie arrière, une paire de becs 11 pour l'accrochage et le verrouillage de la chaussure comme ceci sera décrit plus loin. Chacun de ces becs présente un côté supérieur 13 relativement fortement incliné vers l'arrière du patin (environ 45°) et un côté inférieur 14 faiblement incliné en direction de l'avant du patin.The lock 8 has, at the front, a pair of spouts 12 and, in its rear part, a pair of spouts 11 for hooking and locking the shoe as this will be described later. Each of these mouthpieces has a relatively steep upper side 13 towards the back of the skate (about 45 °) and one side lower 14 slightly tilted towards the front skating.

    L'axe 9 traverse le verrou 8 à travers une lumière 15, plus précisément deux lumières alignées, orientées longitudinalement et permettant au verrou 8 de se déplacer longitudinalement relativement au châssis 2. L'axe 9 est relié à l'entretoise 10 par un ressort de traction 16 tirant le verrou 8 vers l'arrière du patin. Entre la lumière 15 et les becs arrières 11, le verrou 8 présente un second jeu de lumières 17 traversées, avec un jeu important, par un axe 18 fixé transversalement dans le châssis 2. Cet axe 18 et la lumière 17 assurent un guidage du verrou 8, mais avec un jeu vertical suffisant pour ne pas gêner la fixation de la chaussure, comme cela sera décrit plus loin, ainsi que pour permettre le rattrapage du jeu du à l'usure.The axis 9 crosses the latch 8 through a slot 15, more precisely two aligned, oriented lights longitudinally and allowing the latch 8 to be move longitudinally relative to the chassis 2. The pin 9 is connected to the spacer 10 by a spring traction 16 pulling the lock 8 towards the rear of the skate. Between the light 15 and the rear spouts 11, the latch 8 presents a second set of lights 17 crossed, with a large clearance, by a pin 18 fixed transversely in the chassis 2. This axis 18 and the light 17 guide the lock 8, but with enough vertical play so as not to interfere with fixing shoe, as will be described later, as well as to allow the catching up of the game from to wear.

    Le châssis 2 est en outre muni, à l'arrière, d'un levier de déverrouillage 19 articulé sur le châssis autour d'un axe horizontal 20 orienté transversalement au châssis. L'axe 20 est entouré d'un ressort en cor de chasse 21 sollicitant le levier 19 en rotation dans le sens des aiguilles d'une montre, c'est-à-dire vers l'avant du patin. Par son bras de levier inférieur 19a, le levier de déverrouillage 19 repousse le verrou 8 vers l'avant du patin lorsque le levier 19 est basculé vers l'arrière.The chassis 2 is further provided, at the rear, with a release lever 19 articulated on the chassis about a horizontal axis 20 oriented transversely to the chassis. Axis 20 is surrounded by a horn spring flush 21 urging the lever 19 to rotate in the clockwise, i.e. towards the front of the skate. By its lower lever arm 19a, the release lever 19 pushes the lock 8 towards the front of the skate when the lever 19 is tilted rearward.

    La chaussure 1 est munie d'une semelle souple 22 en matière synthétique permettant une marche aisée. Cette semelle 22 présente une creusure centrale 23 s'étendant sur toute la longueur du châssis 2 et dont le fond est de largeur au moins égale à la largeur hors tout du châssis 2. La semelle 22 est surmoulée sur deux inserts, tels que l'insert 29 visible à la figure 2, en matière plastique dure et résistante. Dans ces inserts sont ancrés deux arceaux métalliques en U 24 et 25 dont la partie horizontale 24a, respectivement 25a, constitue une barrette de fixation au châssis. Les bords inférieurs des inserts 29 et les barrettes sont situés en retrait de la surface inférieure de la semelle 22 de manière à ne pas venir en contact avec le sol lors de la marche. Les inserts 29 sont localisés aux endroits de fixation. Ils ne réduisent donc pratiquement pas la souplesse de la semelle lors de la marche. La distance entre les inserts 29 est, de préférence, supérieure à 8 cm de manière à assurer une bonne stabilité de la fixation.Shoe 1 is provided with a flexible sole 22 in synthetic material for easy walking. This sole 22 has a central recess 23 extending over the entire length of chassis 2 and the bottom of which is of width at least equal to the overall width of the chassis 2. The sole 22 is molded on two inserts, such as the insert 29 visible in FIG. 2, in hard and resistant plastic. In these inserts two U-shaped metal arches 24 and 25 are anchored, the horizontal part 24a, respectively 25a, constitutes a fixing bar to the chassis. The lower edges of the inserts 29 and the bars are set back from the bottom surface of the sole 22 so as not to come into contact with the ground when walking. Inserts 29 are located at the fixing points. So they don't reduce practically no flexibility of the sole when market. The distance between the inserts 29 is, from preferably greater than 8 cm so as to ensure good fixation stability.

    Pour le rangement et le transport du châssis sans la chaussure, le levier 19 est avantageusement rabattu sur le châssis. Le levier 19 est relevé, pour le chaussage, dans la position représentée à la figure 3. Le verrou 8, tiré par son ressort 16, est alors en butée contre l'axe 9. Le levier 19, sollicité par son ressort 21, est en butée contre l'extrémité arrière du verrou 8.et il est avantageusement utilisé comme poignée pour tenir le patin. Pour chausser le patin, il suffit de poser le pied sur le châssis 2, de telle sorte que les barrettes 24a et 25a puissent s'engager dans les encoches 4 à 7. Les barrettes 24a et 25a viennent s'appuyer sur les côtés inclinés 13 des becs 11 et 12 du verrou. L'appui de la chaussure sur le châssis a pour effet d'écarter les becs 11 et 12, de telle sorte que les barrettes 24a et 25a peuvent pénétrer au fond des encoches en V du châssis. Le verrou 8 est alors rappelé dans la position représentée à la figure 1 par son ressort 16. Les becs 11 et 12 viennent ainsi verrouiller les barrettes au fond des encoches. Les tolérances de fabrication, ainsi que les jeux dus à l'usure des becs et des barrettes sont rattrapés par l'inclinaison des côtés inférieurs 14 des becs. Au cas où l'usure serait différente sur chacune des barrettes, l'articulation médiane du verrou 8 permet au verrou 8 de compenser, par basculement, cette différence de rattrapage de jeux et/ou par le déplacement relatif d'une plaque 8a, 8b par rapport à l'autre. For storing and transporting the chassis without the shoe, lever 19 is advantageously folded over the chassis. The lever 19 is raised, for putting on, in the position shown in Figure 3. The lock 8, pulled by its spring 16, is then in abutment against the axis 9. The lever 19, biased by its spring 21, is in abutment against the rear end of the latch 8.and it is advantageously used as a handle to hold skate. To put on the skate, just put the foot on frame 2, so that the bars 24a and 25a can engage in the notches 4 to 7. The bars 24a and 25a come to bear on the inclined sides 13 of the nozzles 11 and 12 of the lock. support of the shoe on the chassis has the effect of spreading the nozzles 11 and 12, so that the bars 24a and 25a can penetrate to the bottom of the V-notches of the frame. The lock 8 is then returned to the position shown in Figure 1 by its spring 16. The spouts 11 and 12 thus lock the bars at the bottom of the notches. Manufacturing tolerances, as well that the clearances due to the wear of the spouts and bars are caught by the tilt of the lower sides 14 beaks. In case the wear is different on each of the bars, the central articulation of the lock 8 allows the lock 8 to compensate, by tilting, this difference in catching up of games and / or by the relative displacement of a plate 8a, 8b relative to the other.

    Dans la position chaussée représentée à la figure 1, on remarque la présence d'un jeu e entre le levier de déverrouillage 19 et le verrou 8. Ce jeu est destiné à permettre au levier 19, qui s'appuie contre un collier 26 de la chaussure articulé autour d'un axe 27, de manière bien connue, de suivre le mouvement de pivotement du collier 26 autour de l'axe 27. Le levier 29 prend plus précisément appui dans le fond d'un logement 28 prévu dans le dos du collier 26, les parois latérales de ce logement venant buter contre le levier 19 lors d'une flexion latérale du collier 26, de telle sorte que le levier 19 contribue à la tenue latérale de la chaussure. Un jeu est prévu entre l'extrémité supérieure du levier 19 et le haut du logement 28 pour assurer la liberté de mouvement nécessaire.In the carriageway position shown in Figure 1, we note that there is a clearance e between the lever unlocking 19 and latch 8. This game is intended for allow the lever 19, which rests against a collar 26 of the shoe articulated around an axis 27, of well-known way of following the movement of pivoting of the collar 26 around the axis 27. The lever 29 is more precisely supported in the bottom of a housing 28 provided in the back of the collar 26, the walls side of this housing abutting against the lever 19 during lateral bending of the collar 26, such so that the lever 19 contributes to the lateral holding of the shoe. A clearance is provided between the end top of lever 19 and top of housing 28 for provide the necessary freedom of movement.

    Le verrou 8 pourrait, bien entendu, être constitué d'une pièce massive monobloc, en métal ou en matière synthétique injectée. L'accrochage des barrettes 24a et 25a de la chaussure peut se faire en quatre points, comme dans l'exemple représenté, les points étant en réalité de courte section des barrettes, ou sur toute la longueur de la partie des barrettes située à l'intérieur du châssis. Dans tous les cas, la liaison entre chaussure et châssis a la forme d'un quadrilatère assurant une bonne stabilité latérale de la chaussure sur le châssis.The lock 8 could, of course, be constituted a solid monobloc piece, made of metal or material synthetic injected. The attachment of the bars 24a and 25a of the shoe can be done at four points, as in the example shown, the points being in reality of short section of the bars, or on any the length of the part of the bars located at inside the chassis. In all cases, the connection between shoe and chassis has the shape of a quadrilateral ensuring good lateral stability of the shoe on the chassis.

    Le positionnement et le maintien latéral de la chaussure sur le châssis est assuré par le profil trapézoïdal des inserts 29 dont les côtés obliques viennent s'appuyer sur les bords chanfreinés 30 du châssis 2.The positioning and lateral support of the shoe on the chassis is provided by the profile trapezoidal inserts 29 whose oblique sides come to rest on the chamfered edges 30 of the chassis 2.

    La construction décrite ci-dessus est susceptible de nombreuses autres variantes comprises dans le cadre de l'invention. Quelques unes de ces variantes seront décrites ci-après.The construction described above is likely to many other variations included as part of the invention. Some of these variants will be described below.

    Dans la variante représentée à la figure 4, les plaques parallèles 8a et 8b constituant le verrou sont situées à l'extérieur du châssis, contre les faces extérieures des parois 2a et 2b du châssis. Comme dans le premier mode d'exécution, les plaques 2a et 2b sont reliées par une entretoise 10 qui traverse cette fois les parois 2a et 2b du châssis à travers deux lumières permettant le déplacement du verrou. Les plaques 8a et 8b sont en outre guidées par des épaulements 31 s'étendant sur une partie au moins de la longueur du châssis.In the variant shown in Figure 4, the plates parallels 8a and 8b constituting the lock are located outside the chassis, against the outside faces walls 2a and 2b of the chassis. As in the first embodiment, plates 2a and 2b are connected by a spacer 10 which this time crosses the walls 2a and 2b of the chassis through two lights allowing the moving the lock. The plates 8a and 8b are in further guided by shoulders 31 extending over a at least part of the length of the chassis.

    Les pièces d'accrochage solidaires de la chaussure sont constituées de pièces métalliques en forme de C 32 noyées dans les inserts 29. Les deux extrémités de la pièce 32 forment deux tenons 33, 34 qui s'engagent dans les encoches 4 à 7 du châssis et dans le verrou. Ces tenons 33 et 34 ne font pas ou que très peu saillie à l'intérieur du châssis, de telle sorte qu'un espace se trouve libéré pour des roulettes ou pour le logement d'un frein.The fastening pieces integral with the shoe are made of metal parts in the shape of C 32 embedded in the inserts 29. The two ends of the piece 32 form two studs 33, 34 which engage in notches 4 to 7 on the chassis and in the lock. These let's stick 33 and 34 do not or very little protrude to inside the chassis, so that a space is found free for casters or for housing a brake.

    Le guidage des plaques 8a et 8b du verrou pourrait également être assuré , d'une part, par dessous, par des portées formées sur le châssis, et, d'autre part, par une seule paire de saillies ou tenons solidaires du châssis et coopérant avec des lumières du verrou.The guidance of the plates 8a and 8b of the lock could also be insured, on the one hand, from below, by spans formed on the chassis, and, on the other hand, by a single pair of projections or studs integral with the chassis and cooperating with lock lights.

    La figure 5 représente une exécution du verrou en une seule pièce 35. Cette pièce est, par exemple, formée par découpage et pliage d'une tôle métallique, de manière à former deux parois latérales parallèles 35a et 35b correspondant aux plaques 8a et 8b du premier mode d'exécution, ces plaques 35a et 35b étant reliées par un pont 35c dans leur partie médiane, le verrou 35 reposant sur le châssis par ce pont 35c, de préférence légèrement bombé en direction du châssis et autour d'un axe transversal au châssis, de manière à constituer une surface de basculement sur le châssis pour le rattrapage de jeux différentiels. Dans sa partie médiane, la pièce 35 présente donc une section en U renversé par laquelle le verrou est à cheval sur le châssis.FIG. 5 shows an execution of the lock in one single part 35. This part is, for example, formed by cutting and bending a metal sheet, so as to form two parallel side walls 35a and 35b corresponding to plates 8a and 8b of the first embodiment, these plates 35a and 35b being connected by a bridge 35c in their middle part, the lock 35 resting on the chassis by this bridge 35c, preferably slightly domed towards the chassis and around a axis transverse to the chassis, so as to constitute a tilting surface on the chassis for the catching up with differential play. In its part median, part 35 therefore has a U-shaped section overturned by which the bolt straddles the frame.

    Une barrette ou des tenons de fixation pourraient être obtenus par des pièces de formes différentes. Dans l'exemple représenté à la figure 6, la barrette 36a est constituée par la barre inférieure d'une pièce en I 36 noyée dans l'insert 29.A bar or fixing pins could be obtained by pieces of different shapes. In the example shown in Figure 6, the bar 36a is consisting of the lower bar of an I-piece 36 embedded in insert 29.

    Dans la variante représentée à la figure 7, des tenons 37a et 37b sont constitués par les extrémités d'une pièce en plastique dur 37 noyée par surmoulage dans la semelle 22. Dans ce cas, insert et barrette sont confondus. In the variant shown in Figure 7, tenons 37a and 37b are formed by the ends of a hard plastic part 37 embedded by overmolding in the sole 22. In this case, insert and bar are confused.

    Un deuxième mode d'exécution sera maintenant décrit en relation avec les figures 8 à 10.A second embodiment will now be described in relationship to Figures 8-10.

    Afin d'éviter une multiplication des numéros de références, le châssis 2 et le levier de déverrouillage 19 ont été désignés par les mêmes numéros de références que dans le premier mode d'exécution malgré les différences de forme que l'on peut constater. De même pour les encoches en V 4 et 6.In order to avoid a multiplication of the numbers of references, chassis 2 and unlocking lever 19 have been identified by the same reference numbers that in the first mode of execution despite the differences in form that can be seen. Likewise for V notches 4 and 6.

    Ce mode d'exécution comporte également un élément d'accrochage et de verrouillage commun aux quatre points d'accrochage. Cet élément d'accrochage est constitué de deux barres parallèles 40 qui seront par la suite désignées par le terme verrou pour simplifier. Ce verrou 40 est monté coulissant longitudinalement dans le châssis 2, dans lequel il est guidé entre, d'une part, deux entretoises 41 et 42 du châssis et, d'autre part, trois traverses 43, 44, 49 de ce même châssis. Le verrou 40 est muni de deux crochets 45 et 46 destinés à venir retenir et verrouiller les tenons 24a et 25a de la chaussure. L'extrémité arrière du verrou 40 est articulée au levier de déverrouillage 19 autour d'un axe 47 traversant le châssis 2 à travers une paire de lumières longitudinales telles que la lumière 48 permettant à l'axe 47 de se déplacer longitudinalement sur le châssis. En un point intermédiaire du verrou 40 est articulée, autour d'un axe 50, une gâchette 51 munie à son extrémité d'un crochet 52 par laquelle elle vient s'accrocher sur la traverse 43. La gâchette 51 est munie d'un plot 53 situé juste au-dessus de l'axe 50. A ce plot est accrochée l'extrémité d'un ressort 54 travaillant en traction, dont l'autre extrémité est accrochée au châssis en un point 55. Vu la faible distance entre l'axe 50 et le point d'accrochage 53 du ressort sur la gâchette, le ressort 54 exerce sur la gâchette 51 un couple relativement faible mais tout à fait suffisant pour maintenir la gâchette en position accrochée sur la traverse 43. Ce même ressort 54 a tendance à tirer le verrou 40 vers l'avant avec une force importante. Ce verrou est toutefois retenu par la gâchette 51 elle-même retenue par la traverse 43. Lors du chaussage du patin, les tenons avant 25a, 25b de la chaussure sont engagés les premiers dans les encoches avant 6 et 7 du châssis, conformément à une position normale du pied lors de l'opération de chaussage. Par la suite et pour simplifier la description, nous ne parlerons que des tenons et encoches en V visibles sur le dessin. Cette position est représentée à la figure 8.This embodiment also includes an element hooking and locking common to all four hooking points. This hooking element is consisting of two parallel bars 40 which will be the continuation designated by the term lock to simplify. This lock 40 is mounted to slide longitudinally in chassis 2, in which it is guided between, on the one hand, two spacers 41 and 42 of the chassis and, on the other hand, three sleepers 43, 44, 49 of the same frame. The lock 40 is provided with two hooks 45 and 46 intended to retain and lock the studs 24a and 25a of the shoe. The rear end of the latch 40 is articulated to the unlocking lever 19 around an axis 47 crossing the chassis 2 through a pair of longitudinal lights such as the light 48 allowing axis 47 to move longitudinally on the chassis. At one point intermediate of the latch 40 is articulated around a axis 50, a trigger 51 provided at its end with a hook 52 by which it hangs on the crosspiece 43. The trigger 51 is provided with a stud 53 located just above axis 50. At this stud is hooked on the end of a spring 54 working in traction, the other end of which is attached to the chassis at a point 55. Given the short distance between the axis 50 and the attachment point 53 of the spring on the trigger, the spring 54 exerts on the trigger 51 a relatively low but quite sufficient torque to keep the trigger in the hooked position on the cross 43. This same spring 54 tends to pull the latch 40 forwards with great force. This lock is however retained by the trigger 51 itself retained by the crosspiece 43. When putting on the shoe, the front tenons 25a, 25b of the shoe are first engaged in the notches before 6 and 7 of the chassis in accordance with normal foot position during the fitting operation. Thereafter and for simplify the description, we will only talk about tenons and notches in V visible on the drawing. This position is shown in figure 8.

    Le talon de la chaussure est ensuite abaissé de telle sorte que son tenon arrière 24a vient s'engager dans l'encoche 4. Etant donné que la gâchette 51 traverse le profil de l'encoche 4, comme ceci est visible à la figure 8, le tenon 24a rencontre la gâchette et la repousse vers le bas, comme représenté à la figure 9. Lorsque le tenon 24a rencontre le fond de l'encoche 4, le crochet 52 de la gâchette est libéré de la traverse 43. Le ressort 54 peut alors tirer le verrou 40 vers l'avant de telle sorte que les becs 45 et 46 du verrou viennent verrouiller les tenons 24a et 25a comme représenté à la figure 10. Lors de ce déplacement, le levier 19 est entraíné par son axe 47 dans la lumière 48, mais avant d'arriver en bout de course dans cette lumière, l'extrémité inférieure 19a du levier de déverrouillage 19 arrive en butée contre la traverse 49, de telle sorte que le levier 19 est tiré vers l'avant et qu'il vient s'appuyer, avec une certaine pression, contre le dos de la chaussure. Comme dans le premier mode d'exécution, le levier 19 peut s'engager dans un logement du dos de la chaussure.The heel of the shoe is then lowered so that so that its rear pin 24a engages in the notch 4. Since the trigger 51 crosses the profile of notch 4, as can be seen on the Figure 8, the pin 24a meets the trigger and the pushes back down, as shown in figure 9. When the pin 24a meets the bottom of the notch 4, the trigger hook 52 is released from the cross member 43. The spring 54 can then pull the lock 40 towards the front so that the lugs 45 and 46 of the lock lock the pins 24a and 25a as shown in Figure 10. During this movement, the lever 19 is driven by its axis 47 in the light 48, but before reaching the end of the road in this light, the lower end 19a of the lever unlocking 19 comes into abutment against the cross-member 49, so that the lever 19 is pulled towards the front and that it comes to rest, with a certain pressure, against the back of the shoe. As in the first embodiment, lever 19 can engage in a housing on the back of the shoe.

    Pour libérer la chaussure, il suffit d'exercer une traction vers l'arrière sur le levier 19, dans le sens de la flèche, figure 10. Le levier 19 s'appuie sur le traverse 49 et tire en arrière le verrou 40 avec sa gâchette 51 qui vient à nouveau s'accrocher sur 43 comme représenté à la figure 8.To release the shoe, simply exert a pull back on lever 19, in the direction of the arrow, figure 10. The lever 19 rests on the crosses 49 and pulls back the latch 40 with its trigger 51 which again clings to 43 as shown in figure 8.

    En position déchaussée (figure 8), le levier 19 peut être rabattu sur le châssis.In the bare position (Figure 8), the lever 19 can be folded down on the chassis.

    Le troisième mode d'exécution représenté aux figures 11 à 13 ne diffère essentiellement du deuxième mode d'exécution que par la réalisation de la gâchette. Par conséquent, afin d'éviter des répétitions, les parties ayant la même fonction que dans le deuxième mode d'exécution ont été désignées par les même numéros de références malgré d'éventuelles petites différences de forme. C'est en particulier le cas du verrou 40. Ce verrou 40 est guidé de la même manière que dans le deuxième mode d'exécution et il est relié au levier 19 de manière identique. Le ressort 54 est accroché directement au verrou 40 en un point 56. La gâchette est constituée ici d'un cliquet 57 en corde à piano encastré dans le châssis en un point 58 et s'appuyant sur une traverse 59. Dans la position déverrouillée représentée à la figure 11, ce cliquet 57 est fléchi élastiquement vers le bas et engagé dans une encoche 60 du verrou 40, de telle sorte qu'il retient ce verrou 40 qui est tiré vers l'avant par le ressort 54.The third embodiment shown in Figures 11 at 13 does essentially differ from the second mode of execution than by the realization of the trigger. Through therefore, in order to avoid repetition, the parties having the same function as in the second mode of execution have been designated by the same numbers of references despite possible small differences in form. This is in particular the case of latch 40. This latch 40 is guided in the same way as in the second embodiment and it is connected to lever 19 identically. Spring 54 is hooked directly to the lock 40 at a point 56. The trigger here consists of a ratchet 57 in piano wire embedded in the chassis at a point 58 and supported on a crossmember 59. In the unlocked position shown in Figure 11, this pawl 57 is bent elastically down and engaged in a notch 60 of the lock 40, so that it retains this lock 40 which is pulled forward by the spring 54.

    La figure 11 représente à nouveau la première phase de chaussage dans laquelle les tenons avant 25a, 25b de la chaussure sont engagés dans les encoches avant en V du châssis. Lorsque les tenons arrière s'engagent dans les encoches 4 et 5 du châssis, le tenon 24a rencontre le cliquet 57, comme représenté à la figure 12. Arrivé au fond de l'encoche, le tenon 24a a repoussé suffisamment le cliquet 57 pour que celui-ci s'échappe de l'encoche 60 du verrou 40. Ce verrou 40 peut alors avancer sous l'effet du ressort 54', comme représenté à la figure 13. Pour le reste, ce mode d'exécution est analogue au deuxième mode d'exécution. En particulier, lors de l'action de déverrouillage sur le levier 19, le cliquet 57 glisse sur le verrou 40 pour venir s'engager à nouveau dans l'encoche 60.Figure 11 again shows the first phase of shoe in which the tenons before 25a, 25b of the shoe are engaged in the front V-shaped notches of the frame. When the rear pins engage in the notches 4 and 5 of the chassis, the pin 24a meets the pawl 57, as shown in figure 12. When you reach bottom of the notch, the post 24a has grown back enough the pawl 57 so that it escapes from the notch 60 of lock 40. This lock 40 can then advance under the effect of the spring 54 ', as shown in the figure 13. For the rest, this mode of execution is analogous to second embodiment. In particular, when the unlocking action on the lever 19, the pawl 57 slides on the lock 40 to come to commit to new in notch 60.

    L'encoche 60 pourrait être remplacée par un simple épaulement contre lequel viendrait s'appuyer le cliquet 57.The notch 60 could be replaced by a simple shoulder against which the pawl would lean 57.

    Le troisième mode d'exécution représenté aux figures 14 à 16 se distingue des modes d'exécution précédents par la présence d'éléments d'accrochage et de verrouillage ou verrous distincts pour la fixation des tenons avant et des tenons arrière de la chaussure. The third embodiment shown in Figures 14 to 16 differs from previous modes of execution by the presence of hooking and locking elements or separate locks for fixing the front studs and rear studs on the shoe.

    Comme représenté schématiquement à la figure 14, l'accrochage et le verrouillage est assuré par deux verrous 61 et 62 travaillant en sens opposé. Ces verrous sont réalisés de manière identique, de sorte que l'on se contentera de décrire en détail le verrou 61 en retenant que ce verrou peut être constitué d'une seule pièce ou de deux pièces identiques, une pour chaque tenon de la chaussure, par exemple. Le verrou 61 est en forme de r articulé sur le châssis autour d'un axe 63 et dont la partie supérieure forme un bec 64. Ce verrou présente un plot latéral 65 venant s'engager dans une encoche 66 d'une gâchette 68 constituant un levier du premier genre présentant, en son point d'appui, une découpe cylindrique 69 par laquelle ce levier s'appuie sur un bossage cylindrique 76 du châssis 2 qui lui sert de pivot. La gâchette 68 présente un court bras de levier 70 sur lequel s'appuie un ressort 71 travaillant en compression entre le bras 70 et le verrou 61 et maintenant la gâchette 68 en appui contre le plot 65. Ainsi, lorsque le plot 65 du verrou est engagé dans l'encoche 66 de la gâchette, le verrou 61 est retenu contre l'action du ressort 71.As shown schematically in Figure 14, hooking and locking is ensured by two latches 61 and 62 working in opposite directions. These locks are made identically, so that we will just describe in detail the lock 61 while retaining that this lock may consist of a single piece or two identical pieces, one for each lug of the shoe, for example. Lock 61 is r-shaped articulated on the chassis around a axis 63 and the upper part of which forms a beak 64. This lock has a lateral stud 65 coming to engage in a notch 66 of a trigger 68 constituting a lever of the first kind presenting, in its point support, a cylindrical cutout 69 by which lever rests on a cylindrical boss 76 of the chassis 2 which serves as a pivot. Trigger 68 has a short lever arm 70 on which rests a spring 71 working in compression between the arm 70 and the latch 61 and now the trigger 68 in support against the pad 65. Thus, when the pad 65 of the lock is engaged in the notch 66 of the trigger, the lock 61 is retained against the action of the spring 71.

    Lors du chaussage, comme précédemment, ce sont les tenons 25a, 25b qui s'engagent tout d'abord dans les encoches 6 et 7. Le tenon 25a rencontre la gâchette 72 du verrou 62 et libère ce verrou lorsqu'il arrive au fond de l'encoche 6, comme représenté à la figure 15. L'avant de la chaussure est ainsi accroché et verrouillé. Ce sont ensuite les tenons arrière 24a, 24b qui s'engagent dans les encoches arrière du châssis et qui viennent, de la même manière, s'accrocher et se verrouiller par un verrou 61. Dans cette position, les tenons peuvent écarter les gâchettes des tenons 65, contrairement à ce qui est représenté au dessin.When putting on, as before, these are the let us hold 25a, 25b which engage first of all in the notches 6 and 7. The pin 25a meets the trigger 72 of lock 62 and releases this lock when it reaches the bottom of the notch 6, as shown in FIG. 15. The front of the shoe is thus hooked and Locked. Then there are the rear pins 24a, 24b which engage in the rear notches of the chassis and who come, in the same way, to hang on and lock by a lock 61. In this position, the studs can spread the triggers of studs 65, contrary to what is shown in the drawing.

    Le déverrouillage est assuré par le levier 19 par l'intermédiaire d'un câble 73 dont une extrémité est fixée en 74 au verrou arrière 61, qui passe sur une poulie 75 du verrou avant 62 pour retourner en direction du levier 19 auquel il est fixé par son autre extrémité.Unlocking is ensured by lever 19 by via a cable 73, one end of which is fixed at 74 to the rear lock 61, which passes over a pulley 75 of front lock 62 to return to direction lever 19 to which it is fixed by its other end.
