Description

DISPOSITIF DE FREINAGE POUR PATIN A ROUES BRAKING DEVICE FOR WHEELS
La présente invention concerne un patin du type a roues en ligne comportant une chaussure dont la semelle est apte a être associée a une platine supérieure d'un châssis sur lequel sont disposées les roues de patinage.The present invention relates to a skate of the in-line wheel type comprising a shoe, the sole of which is capable of being associated with an upper plate of a chassis on which the skating wheels are arranged.
Dans ce type de sport, il s'est vite avère indispensable de disposer d'un dispositif de freinage, tant pour pouvoir repondre a des critères de sécurité que pour permettre de réaliser certaines figures de patinage artistique ou acrobatiqueIn this type of sport, it quickly turns out to be essential to have a braking device, both to be able to meet safety criteria and to make it possible to perform certain figures of artistic or acrobatic skating.
C'est ainsi qu'il est souvent prévu de disposer un élément de friction fixe solidaire d'une partie arrière du châssis et susceptible d'entrer en contact par frottement avec le sol, en vue d'un freinage efficace par une action en soulèvement des roues avant, provoquée par le patineurIt is thus often intended to have a fixed friction element integral with a rear part of the chassis and capable of coming into contact by friction with the ground, for effective braking by a lifting action. front wheels, caused by the skater
Un tel principe de freinage entraîne bien entendu l'usure et le remplacement fréquent desdits éléments de friction, ce qui conduit à des opérations de montage et de démontage longues et fastidieuses, d'autant plus qu'en général la fixation de l'élément de friction s'effectue sur l'axe de la roue arrière, ce qui conduit à une intervention sur celle-ci pour monter ou démonter l'élément de frictionSuch a braking principle naturally leads to wear and frequent replacement of said friction elements, which leads to long and tedious assembly and disassembly operations, all the more so as in general the fixing of the element friction takes place on the axis of the rear wheel, which leads to an intervention on the latter to mount or dismount the friction element
De plus, la présence de ce dernier est obligatoire car l'axe de roue est conçu pour en tenir compte Or, il arrive que certains patineurs souhaitent escamoter, dans certains cas, l'élément de friction. Ce n'est donc pas possible selon les cas de figures connues, en tout cas de manière aisée.In addition, the presence of the latter is mandatory because the wheel axle is designed to take it into account. However, some skaters may wish to retract, in certain cases, the friction element. It is therefore not possible according to known cases, in any case easily.
Un autre inconvénient réside dans le fait que ces dispositifs de freinage sont, pour un modèle donné mis en place sur le patin, dès sa sortie de la chaîne de fabrication, ce qui conduit a gérer des volumes de patins plus importants, conduisant à des problèmes d'encombrement tant lors du stockage que lors du conditionnement desdits patins.Another disadvantage lies in the fact that these braking devices are, for a given model put in place on the pad, as soon as it leaves the production line, which leads to managing larger pad volumes, leading to problems. space both during storage and during conditioning of said pads.
De plus, il est parfois souhaité selon le degré de compétence et le style du patineur, de faire varier la garde au sol de l'élément de friction.In addition, it is sometimes desired, depending on the skill level and the style of the skater, to vary the ground clearance of the friction element.
Or, les patins actuels n'offrent pas cette possibilité, également utile pour compenser l'usure du matériau de frictionHowever, the current pads do not offer this possibility, also useful for compensating for the wear of the friction material.
La présente invention a pour but de remédier aux inconvénients précités ou d'atteindre les objectifs évoqués.The present invention aims to remedy the aforementioned drawbacks or to achieve the objectives mentioned.
A cet effet, elle concerne un dispositif de freinage d'un patin a roues comportant un châssis sur une partie inférieure duquel sont disposées les roues de patinage, lequel dispositif est constitue par un élément de friction disposé à une extrémité dudit châssis à proximité du sol, caractérisé en ce que l'élément de friction est associé au châssis par des moyens de verrouillage élastiques amovibles interposés entre ledit élément, directement ou par l'intermédiaire d'un support et le châssis, de manière a autoriser un montage et un démontage rapide de l'élément de friction sans outil, et sans obligation de démontage d'un axe de roue.To this end, it relates to a device for braking a roller skate comprising a chassis on a lower part of which the skating wheels are arranged, which device is constituted by a friction element disposed at one end of said chassis close to the ground , characterized in that the friction element is associated with the chassis by removable elastic locking means interposed between said element, directly or by means of a support and the chassis, so as to allow rapid assembly and disassembly of the friction element without tools, and without the obligation to disassemble a wheel axle.

Le châssis 5 comporte également une partie inférieure perpendiculaire à la platine selon son axe longitudinal et est par exemple, constituée par deux ailes latérales verticales 10a, 10b, parallèles entre elles et disposées de part et d'autre de l'axe longitudinal du châssis. Les ailes latérales 10a, 10b, se prolongent respectivement a leur partie supérieure par un retour perpendiculaire, chacun d'eux étant dirigé vers l'intérieur et constituant un plan correspondant a la platine horizontale 4.The chassis 5 also comprises a lower part perpendicular to the plate along its longitudinal axis and is for example, constituted by two vertical lateral wings 10a, 10b, mutually parallel and arranged on either side of the longitudinal axis of the chassis. The lateral wings 10a, 10b, extend respectively at their upper part by a perpendicular return, each of them being directed inwards and constituting a plane corresponding to the horizontal plate 4.
De cette manière, les ailes latérales verticales 10a, 10b, définissent globalement avec la semelle 3 de la chaussure 2, un "U" renversé entre les ailes duquel sont disposées une pluralité de roues 6, par exemple au nombre de quatre, par l'intermédiaire des axes d'articulation transversaux 12 solidaires du châssis 4 pour constituer un train roulant.In this way, the vertical lateral wings 10a, 10b, define generally with the sole 3 of the shoe 2, a "U" reversed between the wings of which are arranged a plurality of wheels 6, by example four in number, through the transverse hinge pins 12 integral with the chassis 4 to form a running gear.

According to a first embodiment of the invention shown in Figures 1 and 2, the removable locking means of the friction shoe and clevis assembly are constituted by two retractable pins 15a, 15b, arranged on either side of two lateral wings 10a, 10b, of the chassis 10 and capable of cooperating with housings 16, 17, of two corresponding lateral wings 14a, 14b, of a yoke 14 integral with the friction element 13, these housings 16, 17, constituting part of the connection and indexing means with respect to the chassis 5.
En fait, l'indexation de la chape 14, support de l'élément de friction 13 s'effectue par l'intermédiaire d'une encoche 18 en forme de fourche ménagée à l'extrémité libre de chacune de ses ailes latérales 14a, 14b, et apte à coopérer avec des butées correspondantes 19 réalisées de part et d'autre des ailes 10a, 10b, du châssis 5.In fact, the indexing of the yoke 14, support of the friction element 13 is effected by means of a notch 18 in the form of a fork formed at the free end of each of its lateral wings 14a, 14b , and able to cooperate with corresponding stops 19 made on either side of the wings 10a, 10b, of the chassis 5.
Préférentiellement, les pions de verrouillage 15a, 15b, sont constitués par deux éléments cylindriques, d'extrémité arrondie, disposés de part et d'autre des extrémités ouvertes d'un tube correspondant 20 dans lequel ils sont susceptibles de coulisser par pression manuelle, s'effectuant à rencontre d'un ressort à compression 25 interposé entre eux, lequel tube 20 est disposé entre les deux ailes 10a, 10b, du châssis 5 en regard de deux trous de passage 21 ménagés sur la chape 14.Preferably, the locking pins 15a, 15b, are constituted by two cylindrical elements, of rounded end, arranged on either side of the open ends of a corresponding tube 20 in which they are capable of sliding by manual pressure, s 'performing against a compression spring 25 interposed between them, which tube 20 is disposed between the two wings 10a, 10b, of the chassis 5 opposite two through holes 21 formed on the yoke 14.
Ainsi, les pions de verrouillage 15a, 15b, sont chacun sollicités par le ressort 25 à l'extérieur du tube 20 pour s'engager dans les trous 21 et logements 16, 17, associés de la chape 14.Thus, the locking pins 15a, 15b, are each urged by the spring 25 outside the tube 20 to engage in the holes 21 and housings 16, 17, associated with the yoke 14.
Par ailleurs, les pions 15a, 15b, comportent chacun une rainure de coulissement longitudinale 22 fermée à ses extrémités longitudinales, ce qui constitue ainsi des butées de retenue 23, laquelle rainure 22 coopère en coulissement avec une dent fixe 24 réalisée à l'intérieur du tube 20, par exemple par une opération de sertissage, et ayant pour effet de retenir les pions 15a, 15b, à l'intérieur de ce tube, tout en leur autorisant un débattement vers l'intérieur et l'extérieur du tube 20 selon une course correspondant à la longueur de la rainure 22. La variante de réalisation des figures 3 et 4 diffère essentiellement de la précédente en ce que les pions de verrouillage 26a, 26b, sont constitues par deux éléments cylindriques disposes de part et d'autre des extrémités ouvertes d'un tube correspondant 27 dans lequel chacun d'eux est susceptible de coulisser a rencontre d'un ressort de compression associe 28, 29, interpose chacun entre une tête élargie interne 30, 31, de chaque pion 26a, 26b, et une face interne d'une aile correspondante 10a, 10b, du châssis 5, contre la périphérie d'un trou de passage 32 desdits pions 26a, 26b, réalise sur lesdites ailes et en regard de trous de passage 21 de la chape 14A, les pions 26a, 26b, étant commandes simultanément en verrouillage ou en deverrouillage par une came rotative 33 interposée entre les têtes élargies internes 30, 31 , et actionnable depuis l'extérieur de la chape 14A.Furthermore, the pins 15a, 15b each have a longitudinal sliding groove 22 closed at its longitudinal ends, which thus constitutes retaining stops 23, which groove 22 cooperates in sliding with a fixed tooth 24 produced inside the tube 20, for example by a crimping operation, and having the effect of retaining the pins 15a, 15b, inside this tube, while allowing them a movement towards the inside and the outside of the tube 20 according to a stroke corresponding to the length of the groove 22. The variant embodiment of FIGS. 3 and 4 differs essentially from the previous one in that the locking pins 26a, 26b, are constituted by two cylindrical elements arranged on either side of the open ends of a corresponding tube 27 in which each of them is capable of sliding against an associated compression spring 28, 29, each interposed between an internal enlarged head 30, 31, of each pin 26a, 26b, and an internal face of a corresponding wing 10a, 10b , of the chassis 5, against the periphery of a passage hole 32 of said pins 26a, 26b, produced on said wings and opposite passage holes 21 of the yoke 14A, the pins 26a, 26b, being simultaneously controlled by locking or when unlocked by a rotary cam 33 interposed between the internal enlarged heads 30, 31, and actuable from outside the yoke 14A.
Comme le montre la figure 4, la came 33 est en forme d'ellipsoïde et ses moyens de commande pourront être par exemple constitués par une mollette de commande 34 reliée à la came 33 par une tige 34a et agissant en rotation sur ladite came 33, d'un quart de tour dans un sens ou dans l'autreAs shown in FIG. 4, the cam 33 is in the form of an ellipsoid and its control means could for example be constituted by a control wheel 34 connected to the cam 33 by a rod 34a and acting in rotation on said cam 33, a quarter turn one way or the other
Dans un cas comme dans l'autre le montage de l'ensemble patin de friction 13-13A - chape 14-14A s'effectue par engagement des encoches 18 sur les butées 19 correspondantes du châssis, et encliquetage des pions respectivement 15a, 15b, 25a, 26b, dans les logements 16, 17, de la chape support 14-14 AIn one case as in the other, the assembly of the friction shoe 13-13A - yoke 14-14A is effected by engagement of the notches 18 on the corresponding stops 19 of the chassis, and snap-fastening of the pins 15a, 15b respectively, 25a, 26b, in the housings 16, 17, of the support screed 14-14 A
Selon un autre exemple de réalisation de l'invention (figures 5 et 6), les moyens de verrouillage amovibles de l'ensemble patin de friction 13B et chape 14B sont constitués par un levier à rappel élastique 35 monté sur une articulation 40, sous la voûte supérieure 36 d'une chape 14B solidaire de l'élément de friction 13B et comportant un cran de verrouillage 37 traversant une ouverture supérieure 38 de ladite voûte 36 et susceptible de coopérer par encliquetage élastique avec une lumière correspondante 39 réalisée à la partie supérieure d'un logement 41 d'un châssis 5 correspondant a la section de la chape 14B de l'élément de friction 13B et constituant les moyens de liaison et d'indexation par rapport au châssis 5.According to another exemplary embodiment of the invention (FIGS. 5 and 6), the removable locking means of the friction shoe 13B and clevis 14B assembly consist of an elastic return lever 35 mounted on a joint 40, under the upper arch 36 of a yoke 14B secured to the friction element 13B and comprising a locking catch 37 passing through an upper opening 38 of said arch 36 and capable of cooperating by elastic snap-fitting with a corresponding light 39 produced at the upper part d a housing 41 of a chassis 5 corresponding to the section of the yoke 14B of the friction element 13B and constituting the connecting and indexing means relative to the chassis 5.
La section du logement 41 du châssis 5 et la section de la chape 14B de l'élément de friction 13B ont une forme de "T" complémentaire de façon à les rendre susceptibles de coulisser l'un dans l'autre.The section of the housing 41 of the chassis 5 and the section of the yoke 14B of the friction element 13B have a complementary "T" shape so as to make them capable of sliding one inside the other.
Comme le montre bien la figure 6, le coulissement de la chape 14B dans le logement 41 du châssis 5 s'effectue par les branches latérales 42, 43, du "T" formées par la chape 14B, coopérant avec des rainures 44 et 45 réalisées sur les faces internes du châssis 5.As shown in Figure 6, the sliding of the yoke 14B in the housing 41 of the frame 5 is effected by the lateral branches 42, 43, of the "T" formed by the yoke 14B, cooperating with grooves 44 and 45 made on the internal faces of the chassis 5.
Pour le montage, il suffit donc de monter la chape 14B dans le "T" du châssis 5 et de pousser jusqu'à encliquetage du levier 35 dans la lumière 39 du châssis 5, le démontage s'effectuant à l'inverse par pression sur le levier 35 puis par traction sur la chape 14B.For assembly, it suffices therefore to mount the yoke 14B in the "T" of the chassis 5 and to push until the lever 35 clicks into the slot 39 of the chassis 5, the disassembly being carried out in reverse by pressing on the lever 35 then by pulling on the yoke 14B.
Selon le présent exemple, l'organe de rappel élastique du levier de verrouillage 35 est un ressort à compression 46 interposé entre son extrémité libre 35a opposée a son point d'articulation 40 dans la chape 14B de l'élément de friction 13B et une partie fixe correspondante 47 de ladite chapeAccording to the present example, the elastic return member of the locking lever 35 is a compression spring 46 interposed between its free end 35a opposite its point of articulation 40 in the yoke 14B of the friction element 13B and a part corresponding fixed 47 of said yoke
Le mode de réalisation représenté sur la figure 7 diffère essentiellement du précédent en ce que l'organe de rappel élastique du levier de verrouillage 48 est un ressort en épingle 49 articulé sur un point d'articulation central 50 dudit levier, l'une 50a des extrémités libres de ladite épingle étant solidaire de la chape 14C de l'élément de friction 13C, alors que l'autre 50b est fixée sur ledit levier 48 La partie prehensible 48a du levier peut débattre dans une lumière 51 de la chape 14B Ce débattement s'effectue en levant pour obtenir le deverrouillage, contrairement a précédemment ou le déverrouillage s'effectuait en appuyantThe embodiment shown in FIG. 7 differs essentially from the previous one in that the elastic return member of the locking lever 48 is a pin spring 49 articulated on a central articulation point 50 of said lever, one of the free ends of said pin being integral with the yoke 14C of the friction element 13C, while the other 50b is fixed on said lever 48 The gripping part 48a of the lever can debate in a slot 51 of the yoke 14B This movement is carried out by lifting to obtain the unlocking, unlike previously or the unlocking was carried out by pressing
Une autre variante de réalisation représentée sur les figures 8 ou 9 diffère essentiellement des précédentes en ce que les moyens de verrouillage amovibles de l'élément de friction 13D sont constitués, d'une part, par un étner 52, constitué en l'occurrence par une agrafe métallique en forme de "U", et articulé sur le châssis 5 par l'intermédiaire de logements 53 avec lesquels coopèrent les extrémités libres 52a, 52b, dudit étner 52. Celui-ci est de forme telle a rendre apte a envelopper simultanément une chape 14D solidaire de l'élément de friction 13D et une partie arrière dudit châssis 5, dans un logement duquel se positionne la chape 14D, pour constituer les moyens de liaison et d'indexation par rapport audit châssis 5. D'autre part, les moyens de verrouillage comportent un levier-came 54 constituée par un cylindre 55 muni d'un trou longitudinal 56 excentré par rapport à son axe et traversé par une branche de rétrier 52 opposée à son articulation 53, de manière qu'une rotation exercée sur la came 54, préalablement mise en appui sur la chape 14D, porteuse de l'élément de friction 13D, ou directement sur celui-ci, provoque la mise en pression de cette/ce dernier contre le châssis 5.Another variant embodiment shown in FIGS. 8 or 9 differs essentially from the previous ones in that the removable locking means of the friction element 13D consist, on the one hand, of a liner 52, constituted in this case by a metal clip in the shape of a "U", and articulated on the frame 5 by means of housings 53 with which the free ends 52a, 52b of said inner 52 cooperate. The latter is of such a shape as to make it capable of simultaneously enveloping a yoke 14D secured to the friction element 13D and a rear part of said chassis 5, in a housing of which the yoke 14D is positioned, to constitute the connecting and indexing means with respect to said chassis 5. On the other hand, the locking means comprise a cam lever 54 constituted by a cylinder 55 provided with a longitudinal hole 56 eccentric with respect to its axis and traversed by a retrier branch 52 opposite its articulation 53, so that a rotation exerted on the cam 54, previously supported on the yoke 14D, carrying the friction element 13D, or directly on it, causes the pressurization of this / the latter against the chassis 5.
Selon l'exemple de réalisation des figures 10 et 11 , la chape 14E comporte d'une part, dans une partie avant, des glissières 56 coopérant avec des rainures complémentaires 57 de la partie arrière du châssis 5 pour en assurer sa liaison et son indexation et d'autre part, dans une partie arrière, un logement 58 destiné à l'insertion de l'élément de friction 13E, ledit logement 58 étant muni d'une lumière longitudinale 59 assurant à la fois le positionnement du levier-came 54 sur la chape 14E et le maintien dans celle-ci, de l'élément de friction 13E.According to the embodiment of Figures 10 and 11, the yoke 14E comprises on the one hand, in a front part, slides 56 cooperating with complementary grooves 57 of the rear part of the chassis 5 to ensure its connection and its indexing and on the other hand, in a rear part, a housing 58 intended for the insertion of the friction element 13E, said housing 58 being provided with a longitudinal slot 59 ensuring both the positioning of the cam lever 54 on the yoke 14E and the maintenance therein of the friction element 13E.
Par ailleurs, l'étrier 52 est conçu de façon à envelopper, entourer, non seulement la chape 14E et la partie arrière du châssis, mais également l'élément de friction 13F.Furthermore, the stirrup 52 is designed so as to wrap, surround, not only the yoke 14E and the rear part of the chassis, but also the friction element 13F.
L'exemple de la figure 12 diffère également du précédent en ce que la chape 14F comporte des moyens de réglage en hauteur de l'élément de friction 13F d'où de sa garde au sol, qui sont constitues par une pluralité de crans transversaux 60 réalisés sur une paroi interne de fond de la chape avec lesquels crans 60 sont susceptibles de coopérer au moins un cran correspondant 61 réalisé sur une partie arrière du châssis 5The example in FIG. 12 also differs from the previous one in that the yoke 14F comprises means for adjusting the height of the friction element 13F hence its ground clearance, which are constituted by a plurality of transverse notches 60 produced on an inner bottom wall of the yoke with which notches 60 are capable of cooperating at least one corresponding notch 61 produced on a rear part of the chassis 5
L'avantage majeur obtenu par les modes de réalisation des figures 10, 11 et 12, est de permettre le verrouillage et le de verrouillage à la fois de la chape par rapport au châssis et de l'élément de friction par rapport à la chape, facilitant le remplacement de l'un, de l'autre ou des deux à la fois. The major advantage obtained by the embodiments of FIGS. 10, 11 and 12 is to allow the locking and the locking of both the yoke relative to the chassis and the friction element relative to the yoke, making it easier to replace one or the other or both.
