Description

La présente invention a pour objet un patin à roulettes en ligne comprenant au moins trois roulettes dont la roulette arrière et au moins une autre roulette sont montées sur un bâti articulé sur un support de chaussure autour d'un axe parallèle aux axes des roulettes, un frein solidaire dudit support et agissant au moins sur la roulette arrière lors du basculement du support de chaussure vers l'arrière et des moyens de retenue de résistance limitée s'opposant au basculement du support de chaussure vers l'arrière.The subject of the present invention is an in-line roller skate comprising at least three rollers, the rear caster and at least one other caster being mounted on a frame articulated on a shoe support around an axis parallel to the axes of the rollers, a brake integral with said support and acting at least on the rear caster during tilting of the shoe support towards the rear and limited resistance retaining means opposing the tilting of the shoe support towards the rear.

Les patins à roulettes en ligne sont généralement équipés à l'arrière d'un sabot de frein venant freiner par frottement sur le sol lorsque le patineur bascule en arrière sur la roulette arrière. Le freinage obtenu est dépendant de la nature du sol. Il est irrégulier et s'accompagne de vibrations désagréables. Le sabot forme en outre, à l'arrière du patin, une protubérance qui peut être gênante sur un sol irrégulier, en particulier lors de la descente d'une marche ou d'un trottoir.Inline skates are generally equipped at the rear with a brake shoe which brakes by friction on the ground when the skater tips back on the rear caster. The braking obtained is dependent on the nature of the ground. It is irregular and is accompanied by unpleasant vibrations. The hoof also forms, at the rear of the skate, a protuberance which can be troublesome on uneven ground, in particular when descending a step or a sidewalk.

Dans le document EP-A-0 607 817, il a été proposé d'améliorer ce freinage en remplaçant le sabot par un galet fixé à l'extrémité d'un bras d'une bascule dont l'autre bras est muni d'un sabot de frein agissant sur la roulette. Un tel frein dépend encore de la nature du sol et les irrégularités de freinage et des vibrations ne sont pas éliminées et l'on a encore une protubérance gênante à l'arrière.In document EP-A-0 607 817, it has been proposed to improve this braking by replacing the shoe with a roller fixed to the end of an arm of a rocker, the other arm of which is provided with a brake shoe acting on the caster. Such a brake still depends on the nature of the ground and the braking irregularities and vibrations are not eliminated and there is still an annoying protuberance at the rear.

Dans le document DE-A-26 45 192, il est proposé de réaliser un patin à roulettes de descente, à roulettes en ligne ou non, dans lequel le freinage est assuré par le basculement en arrière du support de chaussure sur le bâti des roulettes autour d'un axe situé un peu en avant de la roulette arrière, ce basculement ayant pour effet d'appliquer une garniture de frein sur une roulette solidaire des roulettes arrières ou sur la roulette arrière elle-même. A l'avant, un ressort de rappel a tendance à ramener le support dans sa position normale non freinée.In document DE-A-26 45 192, it is proposed to produce a descent roller skate, with or without inline rollers, in which braking is ensured by the tilting back of the shoe support on the caster frame around an axis located slightly in front of the rear caster, this tilting having the effect of applying a brake lining on a caster secured to the rear casters or on the caster back itself. At the front, a return spring tends to return the support to its normal unbraked position.

Un freinage du même type est également décrit dans le document NL-A-92 01 946. Ce patin comporte une plate-forme montée élastiquement sur quatre roues montées par paires sur des supports oscillants indépendants. La plate-forme est munie à l'arrière d'un sabot de frein venant freiner directement sur la roue arrière. L'axe de basculement de la plate-forme est confondu avec l'axe du support oscillant arrière. Un patin analogue est décrit dans le brevet US 1 342 071.Braking of the same type is also described in document NL-A-92 01 946. This shoe comprises a platform resiliently mounted on four wheels mounted in pairs on independent oscillating supports. The platform is provided at the rear with a brake shoe braking directly on the rear wheel. The tilting axis of the platform coincides with the axis of the rear swinging support. A similar pad is described in US Patent 1,342,071.

Dans tous ces patins, c'est toujours la même zone, étroite, du sabot de frein qui est en contact avec la roulette. Cette zone de frottement s'use donc beaucoup plus vite que le reste du sabot et se polit rapidement, réduisant l'efficacité du freinage. Un remplacement relativement fréquent du sabot de frein est nécessaire.In all these pads, it is always the same narrow area of the brake shoe which is in contact with the caster. This friction zone therefore wears out much faster than the rest of the shoe and polishes quickly, reducing the braking efficiency. Relatively frequent replacement of the brake shoe is necessary.

L'invention a pour but d'éviter un remplacement des sabots de frein et d'augmenter l'efficacité du frein.The object of the invention is to avoid replacing the brake shoes and to increase the effectiveness of the brake.

Le patin à roulettes selon l'invention est caractérisé en ce que le frein est constitué d'au moins une paire de disques coaxiaux opposés présentant chacun une face au moins approximativement tronconique destinée à venir en contact avec un côté de la roulette.The roller skate according to the invention is characterized in that the brake consists of at least one pair of opposite coaxial discs each having an at least approximately frustoconical face intended to come into contact with one side of the caster.

Les disques peuvent être totalement immobilisés et freiner la roulette par frottement sur la roulette elle-même, ou ils peuvent être entraînés par la roulette et freiner par frottement sur une garniture de frein. Dans le premier cas, les disques peuvent être avantageusement immobilisés dans différentes positions angulaires, de telle manière que la partie des disques en contact avec la roulette peut être modifiée. Dans le second cas, la zone des disques en contact avec la roulette change constamment.The discs can be completely immobilized and brake the caster by friction on the caster itself, or they can be driven by the caster and brake by friction on a brake lining. In the first case, the discs can advantageously be immobilized in different angular positions, so that the part of the discs in contact with the roller can be modified. In the second case, the area of the discs in contact with the caster constantly changes.

Selon une forme d'exécution préférée de l'invention, les disques sont entraînés par la roulette et leurs faces opposées aux faces tronconiques sont en contact avec une garniture de frein fixée au bâti ou à un support auxiliaire portant les deux roulettes arrières ou sont munies d'une garniture de frein venant frotter sur le bâti ou le support auxiliaire portant les roulettes arrières. Dans ce cas, le freinage se produit en partie par le frottement sur la garniture de frein de telle sorte que l'échauffement au niveau de la roulette est moins grand et la dissipation de la chaleur au niveau des garnitures est assurée par le bâti, respectivement le support des roulettes arrières.According to a preferred embodiment of the invention, the discs are driven by the wheel and their faces opposite to the frustoconical faces are in contact with a brake lining fixed to the frame or to an auxiliary support carrying the two rear rollers or are provided a brake lining rubbing on the frame or the auxiliary support carrying the rear casters. In this case, braking takes place in part by friction on the brake lining so that the heating at the level of the wheel is less and the dissipation of heat at the level of the linings is ensured by the frame, respectively the support of the rear castors.

Le glissement des disques sur la roulette peut en outre être fortement réduit en formant dans les faces tronconiques des disques une sorte de denture en forme d'alvéoles épousant la forme de la roulette de telle manière que les disques soient plus facilement entraînés par la roulette.The sliding of the discs on the caster can also be greatly reduced by forming in the frustoconical faces of the discs a kind of toothing in the form of cells matching the shape of the caster so that the discs are more easily driven by the caster.

Le patin à roulettes en ligne représenté aux figures 1 et 2 comprend un bâti constitué de deux plaques parallèles 1 et 2 entre lesquelles sont montées quatre roues en ligne 3, 4, 5, 6 montées sur roulement à billes sur des axes tels que l'axe 7. Les plaques 1 et 2 sont maintenues écartées des roulettes par des entretoises 8 et 9 prenant appuis sur les bagues intérieures des roulements à billes.The inline skate shown in Figures 1 and 2 comprises a frame consisting of two parallel plates 1 and 2 between which are mounted four inline wheels 3, 4, 5, 6 mounted on ball bearings on axes such as axis 7. The plates 1 and 2 are kept apart from the rollers by spacers 8 and 9 bearing on the inner rings of the ball bearings.

Le patin comporte une chaussure 10 fixée sur une plate-forme à laquelle sont fixés, à l'arrière, un support 11 et, à l'avant, un plot 12. Le support 11 présente deux ailes verticales 13 et 14 engagées entre les plaques 1 et 2 du bâti. Le support 11 est articulé sur le bâti 1, 2 au moyen d'un axe 15 situé entre les deux roulettes arrières 5 et 6, entre les axes de ces roulettes et la chaussure 10. Entre les ailes 13 et 14 du support 11 sont en outre montées deux paires identiques de disques 16, 17 et 18, 19. La paire de disques 16, 17 est montée sur un axe 20 constitué d'une vis à deux filetages de sens opposé vissée respectivement dans chacun des disques 16 et 17. De même, la paire de disques 18, 19 est montée sur une vis identique 21. Les vis 20 et 21 tournent librement dans le support 11. Les axes des vis 20 et 21 sont à la même distance de l'axe 15 et la distance entre l'axe de la vis 20 et la roulette 6 est la même que la distance entre l'axe de la vis 21 et la roulette 5. Les disques présentent une face tronconique 22 en regard des roulettes et ils sont en outre munis de trous 23 répartis régulièrement et circulairement sur le disque. Ces trous permettent l'immobilisation des disques en rotation au moyen d'une barrette 24, respectivement 25 traversant la paire de disques et les ailes 13 et 14 du support.The skate comprises a shoe 10 fixed on a platform to which are fixed, at the rear, a support 11 and, at the front, a stud 12. The support 11 has two vertical wings 13 and 14 engaged between the plates 1 and 2 of the frame. The support 11 is articulated on the frame 1, 2 by means of an axis 15 located between the two rear casters 5 and 6, between the axes of these casters and the shoe 10. Between the wings 13 and 14 of the support 11 are in further mounted two identical pairs of discs 16, 17 and 18, 19. The pair of discs 16, 17 is mounted on an axis 20 consisting of a screw with two threads of opposite direction screwed respectively into each of the discs 16 and 17. From same, the pair of discs 18, 19 is mounted on an identical screw 21. The screws 20 and 21 rotate freely in the support 11. The axes of the screws 20 and 21 are at the same distance from the axis 15 and the distance between the axis of the screw 20 and the caster 6 is the same as the distance between the axis of the screw 21 and the caster 5. The discs have a frustoconical face 22 facing the rollers and they are furthermore provided with holes 23 distributed regularly and circularly on the disc. These holes allow immobilization of the rotating discs by means of a bar 24, respectively 25 passing through the pair of discs and the wings 13 and 14 of the support.

A l'avant, dans le plot 12, est engagée une vis 26 entre la tête de laquelle et une rondelle 27 est disposé un ressort 28 précomprimé. Entre la rondelle 27 et le plot 12 sont pincées deux chevilles 29 et 30 reliant les plaques 1 et 2 du bâti. L'avant de la chaussure est ainsi retenu élastiquement au bâti, la résistance au basculement autour de l'axe 15 pouvant être réglée en modifiant la précompression du ressort 28 au moyen de la vis 26. Une goupille mobile 31 permet de verrouiller le plot 12 sur le bâti 1, 2 si on le désire.At the front, in the stud 12, a screw 26 is engaged between the head of which and a washer 27 is disposed a precompressed spring 28. Between the washer 27 and the stud 12 are pinched two pins 29 and 30 connecting the plates 1 and 2 of the frame. The front of the shoe is thus retained elastically to the frame, the resistance to tilting around the axis 15 can be adjusted by modifying the precompression of the spring 28 by means of the screw 26. A movable pin 31 makes it possible to lock the stud 12 on frame 1, 2 if desired.

Le freinage se fait par basculement en arrière de la chaussure 10 autour de l'axe 15. Lors de ce basculement, les disques 16 et 17 viennent en contact, par leur face tronconique, de chaque côté de la roulette 6. De la même manière, les disques 18 et 19 de la seconde paire de disques viennent en contact avec la roulette 5. Les disques étant immobilisés en rotation, les roulettes sont freinées par frottement.The braking is done by tilting the boot 10 back around the axis 15. During this tilting, the discs 16 and 17 come into contact, by their frustoconical face, on each side of the caster 6. In the same way , the discs 18 and 19 of the second pair of discs come into contact with the roller 5. The discs being immobilized in rotation, the rollers are braked by friction.

Le pincement des disques peut être réglé au moyen des vis 20 et 21. En cas d'usure des disques, il est possible d'amener une autre zone des disques en contact avec les roulettes en immobilisant les disques dans une autre position angulaire.The pinching of the discs can be adjusted by means of screws 20 and 21. In the event of wear of the discs, it is possible to bring another zone of the discs into contact with the rollers by immobilizing the discs in another angular position.

Les roulettes sont, par exemple, en polyuréthane et les disques en inox ou en bronze.The casters are, for example, in polyurethane and the discs in stainless steel or bronze.

Dans la seconde forme d'exécution représentée aux figures 4 et 5, les disques 16 et 17 sont remplacés par des disques 32 et 33 montés librement sur un axe 34. Ces disques présentent une face extérieure plane en contact avec des garnitures de frein 35 et 36 fixées respectivement aux ailes 13 et 14. Les disques 32 et 33 sont maintenus contre les garnitures de frein par un ressort 37 travaillant sous légère compression entre les deux disques. Les disques 32 et 33 présentent également des faces en regard tronconiques dans lesquelles sont ménagées des creusures 38 formant une sorte de denture conique, ces dentures 38 présentant une forme telle qu'elles s'adaptent au mieux à la forme de la roulette 6.In the second embodiment shown in FIGS. 4 and 5, the discs 16 and 17 are replaced by discs 32 and 33 freely mounted on an axis 34. These discs have a flat outer face in contact with brake linings 35 and 36 fixed respectively to the wings 13 and 14. The discs 32 and 33 are held against the brake linings by a spring 37 working under slight compression between the two discs. The discs 32 and 33 also have frustoconical facing faces in which recesses 38 are formed, forming a sort of conical toothing, these toothing 38 having a shape such that they best adapt to the shape of the caster 6.

Lors du basculement en arrière de la chaussure, la roulette 6 s'engage dans deux rainures 38 des disques de manière à entraîner ces disques en rotation et, simultanément, écarte ces disques l'un de l'autre en les appliquant contre les garnitures de frein 35 et 36. Le freinage ne se produit donc plus seulement par frottement entre la roulette 6 et les disques, mais essentiellement par frottement entre les disques et les garnitures de frein. L'usure de la roulette par freinage est donc fortement réduite et le choix de matériaux adéquat pour les disques et les garnitures de frein permet d'assurer une très grande longévité du frein.During the tilting back of the shoe, the caster 6 engages in two grooves 38 of the discs so as to drive these discs in rotation and, simultaneously, separates these discs from one another by applying them against the linings of brake 35 and 36. Braking therefore no longer occurs only by friction between the wheel 6 and the discs, but essentially by friction between the discs and the brake linings. The wear of the caster by braking is therefore greatly reduced and the choice of suitable materials for the brake discs and linings ensures a very long service life of the brake.

Les garnitures de frein pourraient être fixées aux disques.The brake pads could be attached to the discs.

Selon une variante d'exécution non représentée, la roulette 6 pourrait être munie de deux joues à dentures coniques, en métal ou en matière plastique, destinées à engrener avec une denture conique formée sur les disques de frein. Il serait ainsi possible d'augmenter sensiblement l'efficacité du freinage.According to an alternative embodiment not shown, the caster 6 could be provided with two cheeks with conical teeth, of metal or plastic, intended to mesh with a conical teeth formed on the brake discs. It would thus be possible to significantly increase the braking efficiency.

En combinaison avec le ressort 28 ou en lieu et place de ce ressort, il est possible de prévoir un verrouillage élastique du support avant 12 sur le bâti. Un tel verrouillage peut être réalisé au moyen de deux billes montées dans le support 12 et s'engagent chacune dans un trou de diamètre inférieur aux billes prévu dans chacune des plaques 1 et 2 du bâti et poussées par un ressort travaillant en compression entre les billes. Il est possible ainsi d'éviter un basculement intempestif de la chaussure. Ce verrouillage à cran pourrait être assuré par une seule bille.In combination with the spring 28 or instead of this spring, it is possible to provide an elastic locking of the front support 12 on the frame. Such locking can be achieved by means of two balls mounted in the support 12 and each engage in a hole of diameter smaller than the balls provided in each of the plates 1 and 2 of the frame and pushed by a spring working in compression between the balls . It is thus possible to avoid inadvertent tilting of the shoe. This notch locking could be ensured by a single ball.

Les figures 6 et 7 représentent un mode d'exécution simplifié des moyens s'opposant, à l'avant, au basculement de la chaussure. L'avant de la chaussure 10 est fixé sur un plot 40 en matière synthétique limité latéralement, dans sa partie supérieure et sur un peu moins de la moitié de sa hauteur, par deux parois parallèles 41 et 42, et dans sa partie inférieure, par deux parois latérales 43 et 44 légèrement convergentes. Ce plot 40 est engagé entre les plaques parallèles 1 et 2 du bâti et présente une lumière transversale 45 verticalement. Le plot 40 est pincé entre les plaques 1 et 2 du bâti par un boulon 46 traversant la lumière 45 et muni d'un écrou 47 et d'un paquet de rondelles-ressorts comprimées entre l'écrou 47 et la plaque 1. En position normale de patinage, le boulon 46 est en butée contre l'extrémité supérieure de la lumière 45. L'écrou 47 est serré de telle manière que le patineur peut vaincre le frottement des plaques 1 et 2 contre le plot 40 par un basculement en arrière. Le frottement diminue lorsque le boulon 46 entre la zone des parois convergentes 43 et 44, c'est-à-dire environ le milieu de la lumière 45. L'écrou 47 permet d'ajuster la résistance de la retenue en fonction du poids du patineur.Figures 6 and 7 show a simplified embodiment of the means opposing, at the front, the tilting of the shoe. The front of the shoe 10 is fixed on a stud 40 of synthetic material limited laterally, in its upper part and a little less than half of its height, by two parallel walls 41 and 42, and in its lower part, by two slightly converging side walls 43 and 44. This stud 40 is engaged between the parallel plates 1 and 2 of the frame and has a transverse lumen 45 vertically. The stud 40 is pinched between the plates 1 and 2 of the frame by a bolt 46 passing through the lumen 45 and provided with a nut 47 and a pack of spring washers compressed between the nut 47 and the plate 1. In position normal skating, the bolt 46 is in abutment against the upper end of the light 45. The nut 47 is tightened in such a way that the skater can overcome the friction of the plates 1 and 2 against the stud 40 by tilting back . The friction decreases when the bolt 46 between the zone of the converging walls 43 and 44, that is to say about the middle of the light 45. The nut 47 makes it possible to adjust the resistance of the retainer as a function of the weight of the skater.

Le freinage peut être prévu uniquement sur la roulette arrière 6.Braking can only be provided on the rear caster 6.

Un freinage sur les deux roulettes arrières présente un réel intérêt dans le cas où les quatre roulette sont montées par paires sur des supports oscillant autour d'un axe central. Dans ce cas, l'adhérence des deux roulettes avant peut disparaître, tandis que l'adhérence de l'avant dernière roulette, c'est-à-dire de la roulette 5, est conservée.Braking on the two rear castors is of real interest in the case where the four casters are mounted in pairs on supports oscillating around a central axis. In this case, the adhesion of the two front casters may disappear, while the adhesion of the penultimate roulette, that is to say of the roulette 5, is preserved.

Les figures 8 et 9 représentent une troisième forme d'exécution, caractérisée par le fait que les disques de frein sont montés sur le bâti.Figures 8 and 9 show a third embodiment, characterized in that the brake discs are mounted on the frame.

Dans cette forme d'exécution, la chaussure 10 est fixée de manière absolument rigide et fixe à un bâti 50 constitué de deux plaques parallèles 51 et 52 fixées sur un socle de talon 60 et portant les deux roulettes avant 3 et 4 et deux paires de disques de frein 53, 54 et 55, 56 destinés à freiner respectivement la dernière roulette 6 et l'avant dernière roulette 5. Ces disques sont analogues aux disques 32 et 33 de la deuxième forme d'exécution, lisses ou crantés. Les roulettes arrières 5 et 6 sont montées sur un bâti auxiliaire 57 monté pivotant sur le bâti principal 50 autour d'un axe 61 situé à même distance des axes des roulettes 5 et 6, sous le talon de la chaussure. Le bâti auxiliaire 57 est constitué de deux plaques parallèles 58 et 59 présentant une découpe 62 laissant place au boulon 63 et à l'écrou 64 de la paire de disques 55, 56.In this embodiment, the shoe 10 is fixed in an absolutely rigid and fixed manner to a frame 50 consisting of two parallel plates 51 and 52 fixed on a heel base 60 and carrying the two front casters 3 and 4 and two pairs of brake discs 53, 54 and 55, 56 intended to brake respectively the last caster 6 and the penultimate caster 5. These discs are similar to the discs 32 and 33 of the second embodiment, smooth or notched. The rear rollers 5 and 6 are mounted on an auxiliary frame 57 pivotally mounted on the main frame 50 around an axis 61 located at the same distance from the axes of the rollers 5 and 6, under the heel of the shoe. The auxiliary frame 57 consists of two parallel plates 58 and 59 having a cutout 62 leaving room for the bolt 63 and the nut 64 of the pair of discs 55, 56.

L'articulation 61 est une articulation élastique travaillant en torsion, en l'occurrence un dispositif ROSTA (Marque déposée) tendant à maintenir le bâti auxiliaire 57 dans la position représentée à la figure 8, c'est-à-dire dans une position telle que les quatre roulettes reposent sur un sol horizontal.The articulation 61 is an elastic articulation working in torsion, in this case a ROSTA device (registered trademark) tending to maintain the auxiliary frame 57 in the position shown in FIG. 8, that is to say in a position such that the four casters rest on a horizontal floor.

Pour mémoire, le dispositif ROSTA est constitué d'un arbre 65 de section carrée logé dans un tube fixe 66 également de section carrée, dans lequel l'arbre 65 est maintenu angulairement par quatre barres en matériau élastomère 67. Un tel moyen de torsion pourrait être également utilisé dans les formes d'exécution précédentes en lieu et place des moyens de rappel et de verrouillage à l'avant.As a reminder, the ROSTA device consists of a shaft 65 of square section housed in a fixed tube 66 also of square section, in which the shaft 65 is held angularly by four bars of elastomeric material 67. Such a means of torsion could also be used in the previous embodiments in place of the return and locking means at the front.

Comme dans les cas précédents, le freinage s'effectue en déplaçant le poids du corps vers l'arrière, ce qui a pour effet de faire basculer la chaussure, avec le bâti 50, autour de l'axe 58. Dans ce cas, le poids du patineur reste également réparti sur les roulettes 5 et 6 et le freinage s'effectue de façon égale sur ces deux roulettes.As in the previous cases, braking is carried out by shifting the weight of the body towards the rear, which has the effect of tilting the shoe, with the frame 50, around the axis 58. In this case, the weight of the skater remains equally distributed on the casters 5 and 6 and the braking is carried out equally on these two casters.

L'inclinaison des faces tronconiques des disques est choisie de manière à éviter un coincement des disques entre les roulettes et le bâti par effet de coin tout en évitant un frottement sur la bande de roulement des roulettes et en conservant une composante importante d'application des disques contre les garnitures de frein dans le cas de disques entraînés en rotation. Cette inclinaison est comprise entre 35° et 55°, de préférence 45°.The inclination of the frustoconical faces of the discs is chosen so as to avoid jamming of the discs between the rollers and the frame by wedge effect while avoiding friction on the tread of the rollers and retaining an important component for applying the discs against the brake linings in the case of rotated discs. This inclination is between 35 ° and 55 °, preferably 45 °.

En ce qui concerne l'exécution des bâtis et la répartition des roulettes sur les bâtis, l'invention n'est bien entendu par limitée aux modes d'exécution représentés aux figures 1 et 8. Par exemple, la chaussure pourraît être fixée sur un bâti muni d'une seule roulette à l'avant et articulé sur un bâti muni de trois roulettes. Le freinage pourrait se faire sur ces trois roulettes. Le bâti fixé à la chaussure pourrait être muni de deux roulettes et articulé sur un bâti auxiliaire autour de l'axe de la roulette arrière du bâti principal, les roulettes du bâti auxiliaire étant disposées en avant et en arrière de la roulette arrière du bâti principal. Dans ce cas, le freinage pourrait se faire par une paire de disques agissant simultanément sur les deux roulettes arrières du patin.With regard to the execution of the frames and the distribution of the casters on the frames, the invention is of course not limited to the embodiments shown in Figures 1 and 8. For example, the shoe could be fixed on a frame fitted with a single caster at the front and articulated on a frame fitted with three casters. Braking could be done on these three wheels. The frame fixed to the shoe could be provided with two casters and articulated on an auxiliary frame around the axis of the rear caster of the main frame, the casters of the auxiliary frame being arranged in front of and behind the rear caster of the main frame . In this case, braking could be done by a pair of discs acting simultaneously on the two rear castors of the skate.
