Description

La présente invention concerne les patins à deux roues munis de moyens de freinage.The present invention relates to two-wheel skates provided with braking means.

Le brevet français 2 290 927 décrit des patins à deux roues possédant un châssis, une roue avant et une roue arrière, et deux arbres pour supporter le châssis sur les roues. Une semelle est montée sur le châssis, cette semelle étant sensiblement horizontale et plus basse que les arbres lorsque le patin est en position de fonctionnement avec ses roues dans un plan vertical.French patent 2,290,927 describes two-wheel skates having a chassis, a front wheel and a rear wheel, and two shafts for supporting the chassis on the wheels. A sole is mounted on the chassis, this sole being substantially horizontal and lower than the shafts when the shoe is in the operating position with its wheels in a vertical plane.

Le certificat d'addition français 2 396 569 décrit de tels patins de l'art antérieur dans lesquels sont prévus des moyens de freinage comprenant un levier monté pivotant sur le châssis et possédant à une extrémité un patin de frein susceptible de venir en contact avec la roue arrière du patin. Une lanière de cuir montée à l'autre extrémité du levier permet l'actionnement du frein en exerçant une traction sur la lanière.French certificate of addition 2,396,569 describes such pads of the prior art in which braking means are provided comprising a lever pivotally mounted on the chassis and having at one end a brake pad capable of coming into contact with the rear wheel of the skate. A leather strap mounted at the other end of the lever allows the brake to be actuated by exerting traction on the strap.

Toutefois, du fait des vitesse très élevées qui peuvent être atteintes avec de tels patins et qui peuvent dépasser 50 km à l'heure, de tels moyens de freinage ne sont pas suffisamment efficaces.However, because of the very high speeds which can be reached with such skates and which can exceed 50 km per hour, such braking means are not sufficiently effective.

L'un des buts de la présente invention est de fournir un patin à deux roues présentant une plus grande efficacité de freinage.One of the aims of the present invention is to provide a two-wheeled skate with greater braking efficiency.

Un autre but de l'invention est de fournir un tel patin à deux roues possédant des moyens de freinage puissants tout en évitant tout déport latéral lorsque ces moyens sont utilisés à très grande vitesse.Another object of the invention is to provide such a two-wheeled skate having powerful braking means while avoiding any lateral offset when these means are used at very high speed.

A cet effet, l'invention prévoit un patin à deux roues possédant un châssis, une roue avant et une roue arrière, deux arbres pour supporter ledit châssis sur lesdites roues, une semelle montée sur ledit châssis, ladite semelle étant sensiblement horizontale et plus basse que lesdits arbres lorsque le patin est en position de fonctionnement avec sesdites roues dans un plan vertical, et des moyens de freinage, caractérisé par le fait que lesdits moyens comprennent deux leviers montés pivotants sur ledit châssis, chaque levier ayant à une première de ses extrémités un patin de frein susceptible de venir en contact avec une desdites roues, des moyens d'acctionnement de frein communs pour actionner les deux leviers de frein pour amener en contact lesdits patins avec lesdites roues, et des moyens de liaison pour relier lesdits leviers auxdits moyens d'actionnement de frein.To this end, the invention provides a two-wheeled skate having a chassis, a front wheel and a rear wheel, two shafts for supporting said chassis on said wheels, a sole mounted. on said chassis, said sole being substantially horizontal and lower than said shafts when the shoe is in the operating position with its wheels in a vertical plane, and braking means, characterized in that said means comprise two levers pivotally mounted on said chassis, each lever having at one of its ends a brake shoe capable of coming into contact with one of said wheels, common brake actuation means for actuating the two brake levers to bring said shoes into contact with said wheels , and connecting means for connecting said levers to said brake actuation means.

Etant donné que selon l'invention chaque roue du patin est munie d'un frein, l'efficacité de freinage est améliorée. Mais il a été constaté que, d'une façon surprenante, bien que la roue avant possède un frein, il n'y a pas de déport latéral du fait qu'il est prévu un seul moyen d'actionnement de frein pour les deux leviers de frein.Since, according to the invention, each wheel of the skate is provided with a brake, the braking efficiency is improved. But it has been found that, surprisingly, although the front wheel has a brake, there is no lateral offset because there is only one brake actuation means for the two levers of brake.

Avantageusement, le patin selon l'invention comprend un pneu et une jante possédant une surface cylindrique coaxiale à l'axe de ladite roue, chaque levier étant monté pivotant autour d'un axe parallèle auxdits arbres, chaque patin de frein étant monté sur ladite première extrémité de son levier respectif de telle sorte qu'il soit en vis-à-vis de ladite surface cylindrique, lesdits moyens d'actionnement de frein et lesdits leviers étant reliés auxdits moyens de liaison de telle sorte que chaque levier pivote autour de son axe respectif en réponse à une traction vers le haut exercée sur lesdits moyens d'actionnement de frein de manière à amener en contact chaque patin de frein avec la surface cylindrique de la jante de sa roue respective.Advantageously, the pad according to the invention comprises a tire and a rim having a cylindrical surface coaxial with the axis of said wheel, each lever being mounted pivoting about an axis parallel to said shafts, each brake pad being mounted on said first end of its respective lever so that it faces said cylindrical surface, said brake actuating means and said levers being connected to said connecting means so that each lever pivots about its axis respective in response to an upward pull on said brake actuating means so as to bring each brake shoe into contact with the cylindrical surface of the rim of its respective wheel.

Selon un premier mode de réalisation de l'invention, lesdits leviers sont sensiblement alignés, lesdits moyens de liaison comprenant une tige de liaison sensiblement alignée avec lesdits leviers, et reliée à chacune de ses extrémités avec la deuxième extrémité d'un desdits leviers, lesdits moyens d'actionnement de frein étant fixés à ladite tige de liaison pour faire pivoter les deux leviers en agissant lesdits moyens d'actionnement.According to a first embodiment of the invention, said levers are substantially aligned, said connecting means comprising a connecting rod substantially aligned with said levers, and connected at each of its ends with the second end of one of said levers, said brake actuation means being fixed to said connecting rod to pivot the two levers by acting on said actuation means.

Cet agencement procure un équilibrage efficace de la puissance de freinage entre les deux roues éliminant ainsi toute possibilité de déport latéral lorsque les freins sont actionnés.This arrangement provides efficient balancing of the braking power between the two wheels, thus eliminating any possibility of lateral offset when the brakes are applied.

La tige de connexion peut être reliée de façon lâche à au moins une de ses extrémités avec la deuxième extrémité du levier respectif afin de compenser le changement de la distance entre les deuxièmes extrémités des leviers lorsque les leviers sont pivotés par les moyens d'actionnement de frein.The connecting rod can be loosely connected at at least one of its ends with the second end of the respective lever in order to compensate for the change in the distance between the second ends of the levers when the levers are pivoted by the actuating means of brake.

La tige de connexion est par exemple reliée de façon lâche à son extrémité arrière avec la deuxième extrémité du levier arrière.The connecting rod is for example loosely connected at its rear end with the second end of the rear lever.

Les patins selon l'invention peuvent être munis d'un axe de liaison qui traverse un trou allongé formé, soit dans ladite extrémité reliée de façon lâche de la tige de liaison, soit dans ladite deuxième extrémité de levier respectif, et à travers un trou formé respectivement, soit dans ladite deuxième extrémité du levier respectif, soit dans ladite extrémité reliée de façon lâche de la tige de liaison.The pads according to the invention can be provided with a connecting pin which passes through an elongated hole formed, either in said loosely connected end of the connecting rod, or in said respective second lever end, and through a hole formed respectively, either in said second end of the respective lever, or in said loosely connected end of the connecting rod.

Selon un deuxième mode de réalisation de l'invention, lesdits leviers sont sensiblement parallèles entre eux et verticaux et montés pivotants sur le châssis à proximité de leur deuxième extrémité, lesdits moyens de liaison comprenant un troisième levier monté pivotant sur le châssis, lesdits moyens d'actionnement de frein étant fixés audit troisième levier, et ledit troisième levier étant relié à chacun des deux premiers leviers par un câble de traction.According to a second embodiment of the invention, said levers are substantially parallel to each other and vertical and pivotally mounted on the chassis near their second end, said connecting means comprising a third lever pivotally mounted on the chassis, said means brake actuation being fixed to said third lever, and said third lever being connected to each of the first two levers by a traction cable.

On a constaté que dans ce deuxième mode de réalisation, la puissance de freinage est supérieure et également bien équilibrée entre les deux roues éliminant ainsi les phénomènes de déport latéral.It has been found that in this second embodiment, the braking power is greater and also well balanced between the two wheels thus eliminating the lateral offset phenomena.

On décrira maintenant, à titre d'exemples non limitatifs, deux modes de réalisation de l'invention en référence aux dessins schématiques annexés dans lesquels :

  • - la figure 1 est une vue de côté d'un patin à deux roues selon l'invention, et
  • - la figure 2 est une vue de côté partiellement en coupe verticale d'un patin selon un autre mode de réalisation.
Two embodiments of the invention will now be described, by way of non-limiting examples, with reference to the appended schematic drawings in which:
  • FIG. 1 is a side view of a two-wheeled skate according to the invention, and
  • - Figure 2 is a side view partially in vertical section of a shoe according to another embodiment.

Le patin selon l'invention représenté à la figure 1 comprend essentiellement un châssis 1 supporté par deux arbres 2 et 3 sur une roue avant 4 et une roue arrière 5. Le châssis 1 est constitué de deux longerons latéraux 6 dont les parties centrales sont parallèles et se trouvent dans un plan horizontal plus bas que les arbres des roues. Dans le mode de réalisation représenté, les longerons 6 sont réalisés en tubes coudés.The skate according to the invention shown in FIG. 1 essentially comprises a chassis 1 supported by two shafts 2 and 3 on a front wheel 4 and a rear wheel 5. The chassis 1 consists of two side rails 6 whose central parts are parallel and are in a horizontal plane lower than the shafts of the wheels. In the embodiment shown, the side members 6 are made of bent tubes.

L'extrémité avant 7 et l'extrémité arrière 8 des longerons 6 sont courbées vers le haut et ont un trou que traverse l'arbre respectif 2 ou 3. Des boulons 9 sont vissés aux extrémités de chaque arbre pour maintenir le châssis 1 sur les roues.The front end 7 and the rear end 8 of the side members 6 are curved upwards and have a hole through which the respective shaft 2 or 3 passes. Bolts 9 are screwed to the ends of each shaft to maintain the chassis 1 on the wheels.

Une semelle 10 en tôle d'acier est soudée sur les longerons 6. La semelle est sensiblement rectangulaire de sorte que les longerons 6 sont écartés de la largeur de la semelle. Des moyens de fixation (non représentés) sont montés sur la semelle 10 pour fixer une chaussure d'un utilisateur.A sole 10 of sheet steel is welded to the longitudinal members 6. The sole is substantially rectangular so that the longitudinal members 6 are spaced from the width of the sole. Fastening means (not shown) are mounted on the sole 10 for fixing a shoe of a user.

Chaque roue est constituée d'un pneu 11 monté sur une jante 12. Chaque jante possède une surface intérieure cylindrique 13 coaxiale avec l'arbre respectif 2 et 3.Each wheel consists of a tire 11 mounted on a rim 12. Each rim has a cylindrical inner surface 13 coaxial with the respective shaft 2 and 3.

Une languette 14 est soudée à chaque extrémité de la partie centrale du longeron latéral 6 extérieur.A tongue 14 is welded at each end of the central part of the lateral side beam 6 outside.

Un levier de frein avant 15 est monté pivotant sur la languette avant 14 par l'intermédiaire d'un axe 16. De façon similaire, un levier de frein arrière 17 est monté sur la languette arrière 14 au moyen d'un axe 18. Les axes 16 et 18 sont horizontaux et perpendiculaires au plan vertical axial du patin.A front brake lever 15 is pivotally mounted on the front tongue 14 via a pin 16. Similarly, a rear brake lever 17 is mounted on the rear tongue 14 by means of a pin 18. The axes 16 and 18 are horizontal and perpendicular to the axial vertical plane of the skate.

Chaque levier de frein 15 et 17 possède à son extrémité distale un patin de frein 19 en vis-à-vis de la surface cylindrique 13 respective de la jante 18. Un ressort de rappel 20 monté sur chaque axe 16 et 18 maintient chaque levier de frein dans une position telle que les patins de frein 19 ne sont pas en contact avec les surfaces cylindriques 13 aussi longtemps qu'aucune action n'est exercée sur les leviers de frein 15 et 17.Each brake lever 15 and 17 has at its distal end a brake shoe 19 facing the respective cylindrical surface 13 of the rim 18. A return spring 20 mounted on each axis 16 and 18 holds each lever brake in a position such that the brake pads 19 are not in contact with the cylindrical surfaces 13 as long as no action is exerted on the brake levers 15 and 17.

Les extrémités centrales des leviers 15 et 17 sont reliées à une tige de liaison 21. Les extrémités correspondantes du levier avant 15 et de la tige de liaison 21 sont reliées au moyen d'un axe de liaison 22 traversant deux trous ronds correspondants dans les extrémités du levier 15 et de la tige de liaison 21. Les extrémités correspondantes du levier arrière 17 et de la tige de liaison 21 sont reliées au moyen d'un axe de liaison 23 qui traverse un trou rond dans l'extrémité de la tige de liaison 21 et un trou allongé horizontalement 24 dans le levier 17.The central ends of the levers 15 and 17 are connected to a connecting rod 21. The corresponding ends of the front lever 15 and of the connecting rod 21 are connected by means of a connecting pin 22 passing through two corresponding round holes in the ends lever 15 and connecting rod 21. The corresponding ends of the rear lever 17 and connecting rod 21 are connected by means of a connecting pin 23 which passes through a round hole in the end of the connecting rod 21 and a horizontally elongated hole 24 in the lever 17.

Une lanière d'actionnement 25 a son extrémité inférieure montée sensiblement au milieu de la tige de liaison 21 et possède à son extrémité supérieure une pince 26 pour la fixer à la ceinture d'un utilisateur.An actuating strap 25 has its lower end mounted substantially in the middle of the connecting rod 21 and has at its upper end a clip 26 for fixing it to the belt of a user.

Les leviers de frein 15 et 17 et la tige de liaison 21 sont alignés les uns avec les autres et les axes de liaison 22 et 23 sont horizontaux et perpendiculaires au plan vertical axial du patin, de même que les axes 16 et 18. Par conséquent, lorsqu'un utilisateur tire vers le haut sur la lanière 25, les leviers de frein 15 et 17 sont pivotés par l'intermédiaire de la tige de liaison 21 contre le couple de rappel des ressorts 20, comme montré par les flèches A de la figure 1. En réponse à ce mouvement, les patins de frein 19 viennent en contact avec les surfaces cylindriques respectives 13 des jantes 18, ce qui a pour effet de freiner le patineur.The brake levers 15 and 17 and the connecting rod 21 are aligned with each other and the connecting axes 22 and 23 are horizontal and perpendicular to the axial vertical plane of the shoe, as are the axes 16 and 18. Consequently , when a user pulls up on the strap 25, the brake levers 15 and 17 are pivoted by means of the connecting rod 21 against the return torque of the springs 20, as shown by the arrows A of Figure 1. In response to this movement, the brake pads 19 come into contact with the respective cylindrical surfaces 13 of the rims 18, which has the effect of braking the skater.

Le mouvement de pivotement des leviers de frein 15 et 17 provoque un accroissement de la distance entre leurs extrémités centrales, ce qui est possible du fait que la tige de liaison 21 et le levier 17 sont reliés de façon lâche étant donné la présence du trou allongé 24.The pivoting movement of the brake levers 15 and 17 causes an increase in the distance between their central ends, which is possible because the connecting rod 21 and the lever 17 are loosely connected due to the presence of the elongated hole 24.

La liaison entre les extrémités des leviers 15 et 17, et plus particulièrement l'agencement de la tige de connexion 21, provoque un effet de freinage équilibré, de telle sorte qu'aucun déport latéral n'en résulte.The connection between the ends of the levers 15 and 17, and more particularly the arrangement of the connecting rod 21, causes a balanced braking effect, so that no lateral offset results therefrom.

Un autre avantage de la liaison entre les extrémités centrales des leviers de frein 15 et 17 est que ces leviers ne peuvent pas être accrochés à un obstacle et pliés vers l'extérieur.Another advantage of the connection between the central ends of the brake levers 15 and 17 is that these levers cannot be hung on an obstacle and bent outwards.

Dans la figure 2, les éléments similaires à ceux de la figure 1 ont reçu les mêmes références.In Figure 2, elements similar to those in Figure 1 have been given the same references.

Dans ce mode de réalisation, les leviers de frein 15ʹ et 17ʹ sont montés sur le châssis 1 sensiblement verticaux, pivotant à leur extrémité inférieure autour des axes 16 et 18. Les patins de frein 19 sont montés aux extrémités supérieures des leviers 15ʹ et 17ʹ, dans des trous oblongs permettant d'assurer leur réglage.In this embodiment, the brake levers 15ʹ and 17ʹ are mounted on the substantially vertical chassis 1, pivoting at their lower end around the axes 16 and 18. The brake pads 19 are mounted at the upper ends of the levers 15ʹ and 17ʹ, in oblong holes to ensure their adjustment.

Un troisième levier 30 est monté sur le châssis 1 pivotant autour d'un axe horizontal 31. Ce levier est constitué d'une tige de levier 32 s'étendant à partir de l'axe 31 vers l'arrière du patin, et d'une partie circulaire 33 coaxiale à l'axe 31. Le levier 30 est monté contre le longeron extérieur du patin du côté du plan axial de ce patin. Une découpe 34 dans la semelle 10 permet le passage de la portion inférieure de la partie 33 du levier, celle-ci dépasse le moins possible du châssis afin de ne pas diminuer la garde au sol. L'extrémité de la tige 32 reçoit l'extrémité inférieure de la lanière 25.A third lever 30 is mounted on the chassis 1 pivoting about a horizontal axis 31. This lever consists of a lever rod 32 extending from the axis 31 towards the rear of the shoe, and a circular part 33 coaxial with the axis 31. The lever 30 is mounted against the outer spar of the shoe on the side of the axial plane of this shoe. A cutout 34 in the sole 10 allows the passage of the lower portion of the portion 33 of the lever, it protrudes as little as possible from the chassis so as not to reduce the ground clearance. The end of the rod 32 receives the lower end of the strap 25.

Deux trous diamétralement opposés 35a et 35b sont prévus dans la partie 33, diamétralement opposés par rapport à l'axe 31. Chacun des trous 35a et 35b reçoit l'embout d'un câble de traction 36a et 36b respectivement, par exemple un câble sous gaine.Two diametrically opposite holes 35a and 35b are provided in part 33, diametrically opposite with respect to the axis 31. Each of the holes 35a and 35b receives the end piece of a traction cable 36a and 36b respectively, for example a cable under sheath.

Le câble 36a s'étend à partir du trou supérieur 35a vers l'arrière en traversant une découpe 37 dans la semelle 10 du patin, puis en 38 sous le patin, et il remonte enfin au-delà du bord arrière de la semelle 10, vers l'extrémité supérieure du levier 17ʹ où il est retenu par un autre embout dans un trou 39.The cable 36a extends from the upper hole 35a backwards through a cutout 37 in the sole 10 of the shoe, then at 38 under the shoe, and it finally rises beyond the rear edge of the sole 10, towards the upper end of the lever 17ʹ where it is retained by another end piece in a hole 39.

De façon similaire, le câble de traction 36b s'étend à partir du trou inférieur 35b vers l'avant du patin, tout d'abord en 40 sous la semelle 10, puis au-delà du bord avant de la semelle vers le haut jusqu'à l'extrémité supérieure du levier 15ʹ où il est retenu par un embout dans un trou 41.Similarly, the traction cable 36b extends from the lower hole 35b towards the front of the shoe, first at 40 under the sole 10, then beyond the front edge of the sole upwards 'at the upper end of the lever 15ʹ where it is retained by a nozzle in a hole 41.

Les trous 35a et 35b, dans le levier 30, sont diposés de telle sorte que les câbles 36a et 36b soient, au voisinage de ces trous, le plus perpendiculaires possible au diamètre reliant ces deux trous, de façon à réduire la course de freinage. Dans le cas présent, ce diamètre est incliné de 15° par rapport à la verticale.The holes 35a and 35b, in the lever 30, are arranged so that the cables 36a and 36b are, in the vicinity of these holes, as perpendicular as possible to the diameter connecting these two holes, so as to reduce the braking stroke. In the present case, this diameter is inclined by 15 ° relative to the vertical.

On constate que, lorsqu'une traction est exercée vers le haut sur la lanière 25, elle provoque une rotation du levier 30 dans le sens représenté par la flèche B, ce qui a pour effet d'exercer une traction sur les câbles 36a et 36b, et par conséquent une rotation des leviers 15ʹ et 17ʹ dans le sens des flèches C. Il en résulte une application des patins de frein 19 sur les surfaces cylindriques 13 des jantes des roues, et par conséquent un freinage du patin.It can be seen that, when traction is exerted upwards on the strap 25, it causes rotation of the lever 30 in the direction represented by the arrow B, which has the effect of exerting traction on the cables 36a and 36b , and consequently a rotation of the levers 15ʹ and 17ʹ in the direction of the arrows C. This results in an application of the brake pads 19 on the cylindrical surfaces 13 of the rims of the wheels, and consequently braking of the pad.

Des ressorts de rappel (non représentés) peuvent éventuellement être prévus pour maintenir les leviers 15ʹ et 17ʹ dans une position où les patins 19 ne frottent pas sur les surfaces 13.Return springs (not shown) may possibly be provided to keep the levers 15ʹ and 17ʹ in a position where the pads 19 do not rub on the surfaces 13.

Un ressort de rappel en épingle peut également être monté sur l'axe 31 pour rappeler le levier 30.A pin return spring can also be mounted on the pin 31 to return the lever 30.

Le mode de réalisation représenté à la figure 2 procure également une excellente répartition du freinage entre les roues avant et arrière. En outre, l'utilisation de câbles de traction permet d'obtenir une puissance de freinage supérieure au mode de réalisation de la figure 1. La course de freinage est également très faible et le freinage peut être dosé à volonté.The embodiment shown in Figure 2 also provides an excellent distribution of braking between the front and rear wheels. In addition, the use of traction cables makes it possible to obtain a braking power greater than the embodiment in FIG. 1. The braking stroke is also very low and the braking can be dosed at will.
