Description

DISPOSITIF DE FREIN POUR PATINS ET PLANCHES A ROULETTES BRAKE DEVICE FOR SKATES AND SKATEBOARDS
La présente invention a pour objet un dispositif de frein pour patins et planches à roulettes, à actionnement lors du basculement du patin ou de la planche vers l'arrière par l'appui sur le sol d'une roue montée en rotation à l'une des extrémités d'un élément de levier, le freinage étant obtenu par frottement de l'autre extrémité de l'élément de levier sur chacune des roulettes arrière du patin ou de la planche.The present invention relates to a brake device for skates and skateboards, actuated during tilting of the skate or the board backwards by pressing on the ground a wheel mounted in rotation to one of the ends of a lever element, the braking being obtained by friction of the other end of the lever element on each of the rear rollers of the skate or of the board.
Un dispositif de frein pour patins a roulettes du type ci-dessus est décrit dans le brevet GB-A-25,730. Des dispositifs analogues, dans lesquels un simple élément de sabot fixe remplace la roue montée en rotation à l'extrémité de l'élément de levier sont décrits dans les brevets GB-A-11,117 et US-A-1 ,456,881. Ces dispositifs de conception très ancienne sont pour chacun d'eux conçus en fonction d'un type bien particulier de patins à roulettes. Ils sont fixés au niveau de l'axe de rotation des roulettes et ne pourraient que difficilement être adaptés sur des patins roulettes modernes. D'autre part, ils sont de conception relativement complexe et comportent tous un élément de ressort destiné à repositionner le dispositif à sa position de repos après freinage. Tout élément de ressort pouvant avec le temps se fatiguer et perdre son élasticité, il peut en résulter une altération du fonctionnement du dispositif.A brake device for roller skates of the above type is described in patent GB-A-25,730. Similar devices, in which a simple fixed shoe element replaces the wheel rotatably mounted at the end of the lever element are described in patents GB-A-11,117 and US-A-1, 456,881. These devices of very old design are for each of them designed according to a very specific type of roller skates. They are fixed at the level of the axis of rotation of the rollers and could hardly be adapted on modern roller skates. On the other hand, they are of relatively complex design and all include a spring element intended to reposition the device in its rest position after braking. Any element of spring being able over time to tire and lose its elasticity, this may result in an impairment of the operation of the device.
La plupart des patins a roulettes que l'on trouve actuellement sur le marché sont munis de dispositifs de frein très rudimentaires puisqu'ils sont réalisés sous la forme de simples éléments de caoutchouc ou de plastique disposés de façon fixe à l'avant ou à l'arrière du patin et destinés à un freinage par frottement dudit élément contre le sol lorsque l'on incline le patin respectivement vers l'arrière ou vers l'avant. De tels dispositifs de frein ne sont pas satisfai¬ sants, car, à moins d'être un patineur chevronné, ils provoquent des pertes d'équilibre fréquentes occasionnées par le freinage brusque qu'ils procurent. D'autre part ils s'usent très rapidement.Most of the roller skates that are currently found on the market are fitted with very rudimentary brake devices since they are made in the form of simple rubber or plastic elements fixedly arranged at the front or at the front. rear of the shoe and intended for braking by friction of said element against the ground when the shoe is tilted respectively backwards or towards the front. Such braking devices are not satisfactory, because, unless they are experienced skaters, they cause frequent loss of balance caused by the sudden braking they provide. On the other hand, they wear out very quickly.
Un dispositif du type présenté plus haut, mais conçu pour des patins à roulettes modernes est décrit dans la demande de brevet européen publiée sous no 0039935. Ce dispositif fait partie intégrante de l'essieu supportant une paire de roulettes. Il est conçu de façon que l'élément de levier agisse sur les faces latérales de chacune des roulettes. Il comprend un nombre relativement élevé de pièces et notamment un élément de ressort destiné à remettre le dispositif en position de repos après freinage. Un autre dispositif est décrit dans la demande internationale PCT publiée sous no WO 82/00770. Comme le précédent, ce dispositif est fixé au niveau de l'axe de rotation d'une paire de roulettes. Il est également de conception relativement complexe et comporte également un élément de ressort destiné à son retour en position de repos.A device of the type presented above, but designed for modern roller skates is described in the European patent application published under number 0039935. This device is an integral part of the axle supporting a pair of rollers. It is designed so that the lever element acts on the lateral faces of each of the rollers. It comprises a relatively high number of parts and in particular a spring element intended to return the device to the rest position after braking. Another device is described in the international PCT application published under No. WO 82/00770. Like the previous one, this device is fixed at the level of the axis of rotation of a pair of rollers. It is also of relatively complex design and also includes a spring element intended for its return to the rest position.
Le but de la présente invention est de proposer un dispositif de frein pour patins et planches à roulettes permettant une immobilisation rapide du patin, sans risque de perte d'équilibre, composé d'un nombre restreint de pièces faciles à fabriquer, et pouvant être mises en place sur tous les patins ou planches à roulettes modernes sans modification de ceux-ci.The object of the present invention is to provide a brake device for skates and skateboards allowing rapid immobilization of the skate, without risk of loss of balance, composed of a limited number of parts which are easy to manufacture and can be put in place on all modern skates or skateboards without modification.
A cet effet, l'invention concerne un dispositif de frein pour patins et planches à roulettes, a actionnement lors du basculement du patin ou de la planche vers l'arrière par l'appui sur le sol d'une roue montée en rotation à l'une des extrémités d'un élément de levier, le freinage étant obtenu par frottement de l'autre extrémité de l'élément de levier sur chacune des roulettes arrière du patin ou de la planche, caractérisé en ce qu'il comporte un élément de base destiné à être fixé à la partie arrière du châssis du patin ou de la planche, l'élément de levier étant monté en rotation autour d'un axe solidaire dudit élément de base, l'ensemble étant agencé de façon que l'élément de levier retourne en position de repos par le seul effet du poids de la roue.To this end, the invention relates to a brake device for skates and skateboards, actuated during tilting of the skate or of the board backwards by the pressing on the ground of a wheel mounted in rotation at l 'one end of a lever element, braking being obtained by friction of the other end of the element lever on each of the rear castors of the skate or of the board, characterized in that it comprises a basic element intended to be fixed to the rear part of the chassis of the skate or of the board, the lever element being mounted in rotation around an axis integral with said base element, the assembly being arranged so that the lever element returns to the rest position by the sole effect of the weight of the wheel.
Selon un mode d'exécution, l'élément de base est fixé sur le châssis du patin ou de la planche à l'aide de la vis de fixation de l'essieu des roulettes arrière, l'élément de base pouvant comprendre une partie d'extrémité plate comportant un trou destiné au passage de la vis de fixation de l'essieu des roulettes arrière sur le châssis du patin ou de la planche, la fixation de l'élément de base pouvant alors être obtenue par serrage de ladite partie d'extrémité entre ledit châssis et ledit essieu.According to one embodiment, the basic element is fixed to the frame of the skate or the board using the fixing screw of the axle of the rear rollers, the basic element possibly comprising a part d flat end having a hole for the passage of the fixing screw of the rear wheel axle on the skate or board chassis, the fixing of the base element can then be obtained by tightening said part of end between said chassis and said axle.
Les parties de l'élément de levier destinées à s'appuyer par frottement contre les roulettes peuvent être de même largeur que celle des roulettes du patin ou de la planche et comporter des stries latérales.The parts of the lever element intended to bear by friction against the rollers can be of the same width as that of the rollers of the skate or of the board and comprise lateral grooves.
L'élément de base peut comporter une partie évidée destinée au centrage et au blocage du dispositif de frein autour du dispositif de centrage/blocage de l'essieu des roulettes arrière.The basic element may include a recessed portion intended for centering and blocking the brake device around the centering / blocking device for the axle of the rear rollers.
La partie d'extrémité de l'élément de base peut comporter une partie proéminente en forme de rondelle disposée autour du trou.The end portion of the base member may have a prominent washer-shaped portion disposed around the hole.
Le dispositif peut être réalisé par exemple en métal ou en matière plastique.The device can be made for example of metal or plastic.
Ce dispositif a l'avantage de pouvoir être monté de façon très simple, par qui que ce soit, en une seule opération sur tous les patins et planches à roulettes modernes. Il comporte un nombre de pièces très limité, simples â réaliser. De plus, son fonctionnement n'est pas susceptible d'être altéré avec le temps, puisqu'il ne comporte aucun élément de ressort pour le retour en position de repos.This device has the advantage of being able to be mounted very simple way, by anyone, in a single operation on all modern skates and skateboards. It includes a very limited number of parts, simple to make. In addition, its operation is not likely to be altered over time, since it has no spring element for returning to the rest position.

la fig. 11 est une coupe verticale transversale selon B-B de la figure 8.fig. 11 is a vertical transverse section along B-B in FIG. 8.
Comme représenté sur les figures 1 a 3, le dispositif de frein comprend un élément de base 1 destiné à être fixé sur le châssis du patin à roulettes. Un élément de levier 9 est monté en rotation sur l'élément de base 1 autour d'un élément d'axe 7. Une roue 14 est montée en rotation a l'une des extrémités de l'élément de levier, autour d'un élément d'axe 13. L'élément de base comporte une première partie d'accrochage 2 ayant une surface plane et comportant un trou 4 destiné à la fixation dudit élément de base sur le patin, et une seconde partie 3, inclinée dans le sens longitudinal par rapport à la première partie 2, et comportant une partie creuse sOuvrant vers l'extérieur, de façon à diminuer la quantité de matière et formant deux branches 6, 6' et constituant un espace vide 5 qui permet le centrage et le blocage du dispositif de frein en position après sa mise en place, de la même façon que le blocage en position de l'essieu des roulettes arrière. Chacune des branches 6, 6' est transpercée à son extrémité par un trou dirigé latéralement et destiné au passage de l'élément d'axe 7 disposé perpendiculairement par rapport à l'axe de symétrie longitudinal 8 du dispositif. L'élément de levier 9 comporte d'une part deux parties 10, 10' en forme d'ailettes, disposées longitudinalement et symétriquement par rapport à l'axe de symétrie 8, et espacées de façon que l'on puisse insérer entre elles les deux branches 6, 6' de l'élément de base. Des trous sont également prévus a la base desdites parties en forme d'ailettes de façon à permettre le passage de l'élément d'axe 7 permettant à l'élément de levier 9 d'effectuer une rotation par rapport â l'élément de base 1. L'élément de levier 9 comporte d'autre part une partie 11 , longitudinalement, inclinée par rapport aux parties 10, 10' et agencée en forme de fourche à deux branches 12, 12' s'étendant dans la direction opposée à celle des parties en forme d'ailettes 10, 10' et comportant à leurs extrémités des trous disposés transversalement, de façon à permettre le passage de l'élément d'axe 13 sur lequel est monté en rotation la roue 14.As shown in Figures 1 to 3, the brake device comprises a basic element 1 intended to be fixed to the chassis of the roller skate. A lever element 9 is rotatably mounted on the base element 1 around an axis element 7. A wheel 14 is rotatably mounted at one end of the lever element, around a axis element 13. The base element comprises a first attachment part 2 having a flat surface and comprising a hole 4 intended for fixing said base element to the shoe, and a second part 3, inclined in the direction longitudinal with respect to the first part 2, and comprising a hollow part opening towards the outside, so as to reduce the quantity of material and forming two branches 6, 6 ′ and constituting an empty space 5 which allows the centering and the blocking of the brake device in position after its installation, in the same way as the locking in position of the rear wheel axle. Each of the branches 6, 6 'is pierced at its end by a laterally directed hole intended for the passage of the axis element 7 disposed perpendicularly to the longitudinal axis of symmetry 8 of the device. The lever element 9 comprises on the one hand two parts 10, 10 ′ in the form of fins, arranged longitudinally and symmetrically with respect to the axis of symmetry 8, and spaced apart so that the two branches 6, 6 'of the basic element. Holes are also provided at the base of said wing-shaped parts so as to allow passage of the axis element 7 allowing the lever element 9 to rotate relative to the base element 1. The lever element 9 also comprises a part 11, longitudinally, inclined by relative to the parts 10, 10 ′ and arranged in the form of a fork with two branches 12, 12 ′ extending in the opposite direction to that of the parts in the form of fins 10, 10 ′ and having holes arranged transversely at their ends, so as to allow the passage of the axle element 13 on which the wheel 14 is mounted to rotate.
Le montage du dispositif de frein sur le patin s'effectue de façon très simple. Il suffit de dévisser l'essieu des roulettes arrière, de placer la face plane de la partie 2 de l'élément de base contre le châssis du patin en positionnant le trou 4 en face du trou destiné à la vis de fixation dudit essieu et de replacer l'essieu, de façon à immobiliser la partie 2 de l'élément de base entre le châssis et l'essieu a l'aide de la vis de fixation de l'essieu. A l'état de repos, c'est-à-dire lorsque le patin est en position horizontale, le poids de l'ensemble constitué par la roue et la partie 11 de l'élément de levier étant supérieur au poids des ailettes 10, 10' dudit élément de levier, lesdites ailettes subissent une poussée vers le haut et viennent buter contre le châssis du patin. Les dimensions et le positionnement des pièces du dispositif de frein sont choisis de façon que le point le plus bas de la roue 14 se trouve situé sensiblement plus haut que le point le plus bas des roulettes 15 du patin. Pour freiner il suffit de faire basculer le patin vers l'arrière en soulevant l'avant du patin. De cette façon, la roue 14 vient s'appuyer contre le sol et fait basculer l'élément de levier 9 autour de l'axe 7, les parties en forme d'ailettes 10, 10' venant alors s'appuyer sur les roulettes 15 du patin. Après freinage, lorsque le patin retrouve sa position horizontale, le dispositif de frein se remet automatiquement en position de repos sous 1'effet du poids de la roue comme mentionné plus haut.The mounting of the brake device on the shoe is very simple. It suffices to unscrew the axle of the rear castors, to place the flat face of part 2 of the basic element against the frame of the skate by positioning hole 4 opposite the hole intended for the fixing screw of said axle and replace the axle so as to immobilize part 2 of the basic element between the chassis and the axle using the axle fixing screw. In the rest state, that is to say when the shoe is in the horizontal position, the weight of the assembly constituted by the wheel and the part 11 of the lever element being greater than the weight of the fins 10, 10 'of said lever element, said fins undergo an upward thrust and abut against the frame of the skate. The dimensions and positioning of the parts of the brake device are chosen so that the lowest point of the wheel 14 is located substantially higher than the lowest point of the rollers 15 of the shoe. To brake, simply tilt the skate backwards by lifting the front of the skate. In this way, the wheel 14 comes to rest against the ground and swings the lever element 9 around the axis 7, the parts in the form of fins 10, 10 ′ then coming to bear on the rollers 15 skating. After braking, when the shoe returns to its horizontal position, the brake device automatically returns to the rest under the effect of the weight of the wheel as mentioned above.
Une variante d'exécution de l'élément de levier est représentée sur les figures 5 et 6. Les parties en forme d'ailettes 21, 21* de l'élément de levier 20 représentées sur ces figures comportent des rainures latérales 22 disposées sur leurs faces inférieures de façon à augmenter l'effet de fixation sur les roulettes 15 du patin ou de la planche lors du freinage.An alternative embodiment of the lever element is shown in FIGS. 5 and 6. The fin-shaped parts 21, 21 * of the lever element 20 shown in these figures have lateral grooves 22 arranged on their lower faces so as to increase the fixing effect on the rollers 15 of the skate or the board during braking.
Une variante d'exécution de l'élément de base est représentée sur les figures 7 à 10. Cet élément de base comporte également un trou 31 destiné à sa fixation sur le patin. La forme générale de cet élément de base est sensiblement différente de celle de l'élément de base décrit plus haut et est particulièrement adaptée pour être réalisée en matière plastique. L'élément 30 comporte un élément de rondelle incorporé 32, disposé autour du trou 31, de façon à faciliter l'adaptation de l'élément de base sur tous les patins du commerce. En effet, cette partie en forme de rondelle, lorsqu'elle est réalisée en matière plastique, peut facilement être retouchée, par exemple par limage ou fraisage avant d'être montée sur le patin. Afin de renforcer sa rigidité, l'élément 30 comporte deux raidisseurs longitudinaux 33. La partie creuse 34 est destinée à remplacer la partie vide 5 de l'élément de base décrit à la figure 1.An alternative embodiment of the base element is shown in FIGS. 7 to 10. This base element also includes a hole 31 intended for its attachment to the shoe. The general shape of this basic element is significantly different from that of the basic element described above and is particularly suitable for being made of plastic. The element 30 comprises an incorporated washer element 32, disposed around the hole 31, so as to facilitate the adaptation of the base element on all the pads of the trade. Indeed, this washer-shaped part, when made of plastic, can easily be touched up, for example by filing or milling before being mounted on the skate. In order to reinforce its rigidity, the element 30 comprises two longitudinal stiffeners 33. The hollow part 34 is intended to replace the empty part 5 of the basic element described in FIG. 1.
Bien entendu, les exemples du dispositif de frein décrits ci-dessus peuvent être montés sur des patins à roulettes ou des planches à roulettes. Ils peuvent être exécutés en toute matière métallique ou, de préférence, en matière plastique, ce qui permet une réalisation plus légère facilitant la liberté de mouvement de l'utilisateur. Ils peuvent comporter des parties visibles de couleur vive, ou réfléchissantes, ou phosphorescentes ou fluorescentes, de façon à rendre mieux visible le patineur et à augmenter sa sécurité dans le trafic.Of course, the examples of the brake device described above can be mounted on roller skates or skateboards. They can be executed in any metallic material or, preferably, in plastic material, which allows a lighter embodiment facilitating the freedom of movement of the user. They may have visible parts of bright color, or reflective, or phosphorescent or fluorescent, so as to make the skater better visible and to increase his safety in traffic.
Comme on peut le voir sur les figures, dans les exemples donnés les parties 10, 21 en forme d'ailettes des éléments de levier ont sensiblement la même largeur que les roulettes de façon à augmenter la surface de frottement. D'autre part, leur épaisseur sera de préférence calculée pour rester le plus mince possible, de façon à permettre un bon refroidissement. As can be seen in the figures, in the examples given the parts 10, 21 in the form of fins of the lever elements have substantially the same width as the rollers so as to increase the friction surface. On the other hand, their thickness will preferably be calculated to remain as thin as possible, so as to allow good cooling.
