Abstract

The roller blade comprises three in line rollers (5,6,9), carried by a main chassis (1). A rear wheel (10) is mounted on an auxiliary chassis (8) pivoted on the main chassis. A pair of rotating discs (13) have truncated faces applied to the rear wheels (6,10) during rearward tipping of the skate. Braking is then assured by the rubbing of these discs on the non-rotating parts of the roller blade. The auxiliary chassis is pivoted about the axis (7) of the main chassis last wheel. Mechanical connection between the main chassis axis (12) and the auxiliary chassis is constituted by a slots (11) in the auxiliary chassis. The disc spindles are engaged in the slots (15) of the main chassis, transverse to the auxiliary chassis slots.

Description

La présente invention a pour objet un patin à roulettes en ligne comprenant au moins trois roulettes dont au moins la roulette arrière est montée sur un châssis auxiliaire articulé sur un châssis principal supportant une chaussure autour d'un axe parallèle à l'axe des roulettes et un frein lié cinématiquement au châssis auxiliaire de manière à freiner au moins l'avant-dernière roulette lors du basculement, en arrière, du patin sur l'avant-dernière roulette, et des moyens élastiques s'opposant à ce basculement.The subject of the present invention is an in-line roller skate comprising at least three rollers, at least the rear wheel of which is mounted on an auxiliary chassis articulated on a main chassis supporting a shoe around an axis parallel to the axis of the rollers and a brake kinematically linked to the auxiliary chassis so as to brake at least the penultimate caster during tilting, backwards, of the shoe on the penultimate caster, and elastic means opposing this tilting.

Un tel patin est connu de la demande de brevet EP 0 677 310. Dans ce patin, c'est une partie du châssis auxiliaire qui constitue un sabot de frein venant en contact avec la bande de roulement de l'avant-dernière roulette lors du basculement du châssis principal sur l'avant-dernière roulette. Additionnellement, l'arrière du châssis principal vient s'appuyer sur la dernière roulette pour freiner celle-ci. Le poids du patineur s'exerce entre les deux roulettes arrière. Les moyens s'opposant au basculement sont constitués d'un ressort travaillant en compression entre les châssis et précontraint. Un réglage de la précontrainte est dès lors nécessaire en fonction du poids du patineur. Le ressort peut en outre être totalement précontraint de manière à empêcher un basculement du châssis principal relativement au châssis auxiliaire, le patin se comportant alors comme un patin à châssis unique à quatre roulettes et sans frein.Such a shoe is known from patent application EP 0 677 310. In this shoe, it is a part of the auxiliary chassis which constitutes a brake shoe coming into contact with the tread of the penultimate roller during the tilting of the main chassis on the penultimate caster. Additionally, the rear of the main chassis comes to rest on the last caster to brake it. The weight of the skater is exerted between the two rear casters. The means opposing the tilting consist of a spring working in compression between the chassis and prestressed. Adjustment of the preload is therefore necessary depending on the weight of the skater. The spring can also be fully prestressed so as to prevent the main chassis from tilting relative to the auxiliary chassis, the shoe then behaving like a single chassis shoe with four casters and without brake.

Du brevet US 5 088 748, on connaît par ailleurs un patin muni à l'arrière d'une roulette auxiliaire articulée à l'extrémité d'un bras lui-même articulé à l'extrémité arrière du châssis, cette roulette ne venant en contact avec le sol que lors du basculement du patin sur la roulette arrière, l'appui de la roulette auxiliaire appliquant un frein sur la roulette arrière ou la tranche d'un disque solidaire de la roulette arrière et concentrique à celle-ci.From US Pat. No. 5,088,748, there is also known a shoe provided at the rear with an auxiliary wheel articulated at the end of an arm itself articulated at the rear end of the chassis, this caster coming into contact with the ground only when the shoe is tilted on the rear caster, the support of the auxiliary caster applying a brake on the rear caster or the edge of a disc integral with the rear wheel and concentric with it.

Le brevet US 5 375 859 décrit un patin analogue dans lequel le frein est constitué de deux freins à disques montés de chaque côté de la roulette arrière, le freinage se faisant par l'application de disques fixes en rotation contre des disques en forme de couronne solidaires de la roulette. La chaleur dégagée par le freinage doit être dans une partie importante évacuée par la roulette elle-même et l'échauffement de la roulette est telle que celle-ci peut être détériorée.US Patent 5,375,859 describes a similar pad in which the brake consists of two disc brakes mounted on each side of the rear caster, the braking being effected by the application of fixed discs in rotation against discs in the form of a crown. in solidarity with roulette. The heat released by braking must be largely removed by the wheel itself and the heating of the wheel is such that it can be deteriorated.

Dans ce type de patin à frein commandé par la roulette auxiliaire ne venant en contact avec le sol qu'après basculement du patin d'un certain angle, il est en outre difficile d'avoir un freinage initial progressif compte tenu de l'absence totale d'équilibre du patin s'appuyant sur une seule roulette pendant la première phase de basculement, ceci d'autant plus qu'avant basculement, le poids du corps agit en avant de la roulette arrière et qu'il faut donc d'abord amener le poids du corps à la verticale de l'axe de la roulette arrière.In this type of brake shoe controlled by the auxiliary wheel coming into contact with the ground only after tilting the shoe by a certain angle, it is also difficult to have a progressive initial braking given the total absence of balance of the skate resting on a single caster during the first tilting phase, this all the more so since before tilting, the body weight acts in front of the rear caster and it is therefore necessary first to bring the weight of the body vertical to the axis of the rear caster.

La présente invention a pour but d'obtenir un freinage plus régulier, plus facile à contrôler et sans échauffement notable des roulettes.The present invention aims to obtain a more regular braking, easier to control and without significant heating of the rollers.

Le patin à roulettes en ligne selon l'invention est caractérisé en ce que le frein est constitué d'une paire de disques coaxiaux opposés montés rotativement et maintenus écartés l'un de l'autre par un moyen élastique, les faces en regard de ces disques étant au moins approximativement tronconiques et destinées à venir en contact avec les deux côtés des deux roulettes arrière pour leur entraînement en rotation par les roulettes arrière, le freinage étant assuré pour le frottement des disques sur des parties du patin fixes en rotation et que l'axe de ces disques est situé entre les deux roulettes arrière , au-dessus des axes de ces roulettes, et à distance égale de ces axes, et que la liaison mécanique entre les disques et le châssis auxiliaire est telle que lors du basculement du patin vers l'arrière, cet axe descend en direction de la droite reliant les axes des deux roulettes arrière, de telle manière que les disques sont appliqués sur les deux roulettes arrière.The inline roller skate according to the invention is characterized in that the brake consists of a pair of opposite coaxial discs rotatably mounted and kept apart from one another by elastic means, the facing faces of these discs being at least approximately frustoconical and intended to come into contact with the two sides of the two rear rollers for their driving in rotation by the rear rollers, the braking being ensured for the friction of the discs on parts of the shoe fixed in rotation and that the axis of these discs is located between the two rear casters, above the axes of these rollers, and at equal distance from these axes, and that the mechanical connection between the discs and the auxiliary chassis is such that during the tilting of the shoe towards the rear, this axis descends in the direction of the right connecting the axes of the two rear castors, such that the discs are applied to the two rear casters.

Lors du freinage, les disques sont tirés vers le bas et appliqués sur les deux roulettes arrière, ce qui assure une pression régulière de l'avant-dernière roulette sur les disques.When braking, the discs are pulled down and applied to the two rear casters, which ensures regular pressure of the penultimate caster on the discs.

Les disques étant entraînés en rotation par les deux roulettes arrière, le freinage se fait par friction entre les disques et le châssis principal. De préférence, les disques sont eux-mêmes en un matériau utilisé pour les garnitures de frein et frottent directement sur l'un des châssis principal ou sur un disque métallique fixé au châssis, ce qui évite l'échauffement des roulettes et favorise l'évacuation de la chaleur par le châssis.The discs being driven in rotation by the two rear castors, braking is done by friction between the discs and the main chassis. Preferably, the discs are themselves made of a material used for the brake linings and rub directly on one of the main chassis or on a metal disc fixed to the chassis, which prevents the heating of the rollers and promotes evacuation heat through the chassis.

Le dessin annexé représente, à titre d'exemple, quatre formes d'exécution de l'invention.The accompanying drawing shows, by way of example, four embodiments of the invention.

La figure 8 représente une quatrième forme d'exécution en position de roulement non freinée.FIG. 8 represents a fourth embodiment in the unbraked rolling position.

La figure 9 représente ce même patin en position de freinage.Figure 9 shows the same shoe in the braking position.

Le patin représenté à la figure 1 comprend un châssis principal 1 constitué d'une pièce profilée en U et découpée de manière à présenter une plateforme avant 2 et une plateforme arrière 3 qui supportent une chaussure 4. Le châssis 1 est muni de deux roulettes 5 et 6. La roulette 5 est en avant de la plateforme avant 2 tandis que la roulette 6 est située sous la plateforme arrière 3, de telle sorte que son axe 7 est situé sous le talon de la chaussure 4. Sur le châssis 1, autour de l'axe 7 de la roulette 6, est articulé un châssis auxiliaire 8 qui peut également être constitué d'une pièce profilée en U s'emboîtant dans le châssis principal 1 ou de deux plaques entretoisées. Ce châssis auxiliaire 8 porte deux roulettes 9 et 10, la roulette 9 étant située entre les roulettes 5 et 6 et la roulette 10 en arrière du châssis principal 1. La roulette 9 est facultative.The skate shown in Figure 1 comprises a main frame 1 consisting of a U-shaped part and cut so as to present a front platform 2 and a rear platform 3 which support a shoe 4. The frame 1 is provided with two rollers 5 and 6. Roulette 5 is in front of the front platform 2 while the caster 6 is located under the rear platform 3, so that its axis 7 is situated under the heel of the shoe 4. On the chassis 1, around the axis 7 of the caster 6, is articulated a auxiliary chassis 8 which may also consist of a U-shaped piece fitting into the main chassis 1 or of two braced plates. This auxiliary chassis 8 carries two rollers 9 and 10, the roller 9 being located between the rollers 5 and 6 and the roller 10 behind the main chassis 1. The roller 9 is optional.

Le châssis auxiliaire 8 présente deux lumières identiques 11, vis-à-vis l'une de l'autre, situées entre les deux roulettes arrière 6 et 10, à égale distance des axes des roulettes 6 et 10 et s'étendant perpendiculairement à la droite reliant ces axes. Les lumières 11 sont traversées par un axe 12 de diamètre correspondant à la largeur de ces lumières, cet axe 12 portant une paire de disques 13 dont les faces en regard sont tronconiques (figure 2), ces disques étant montés librement sur l'axe 12, au moins axialement, et étant maintenus écartés l'un de l'autre, en appui contre les parois du châssis auxiliaire 8, par un élément élastique 14. L'axe 12 peut donc se déplacer verticalement dans les lumières 11. Les extrémités des axes 12 sont en outre engagées dans une paire de lumières 15 ménagées dans le châssis principal 1. Les lumières 15 sont légèrement inclinées en direction de l'avant-dernière roulette 6. Les disques 13 sont, de préférence, en un matériau de type Ferodo (Marque déposée) et leurs faces extérieures planes sont directement appliquées contre le châssis auxiliaire 8.The auxiliary chassis 8 has two identical slots 11, facing one another, located between the two rear rollers 6 and 10, equidistant from the axes of the rollers 6 and 10 and extending perpendicular to the right connecting these axes. The lights 11 are crossed by an axis 12 of diameter corresponding to the width of these lights, this axis 12 carrying a pair of discs 13 whose facing faces are frustoconical (Figure 2), these discs being freely mounted on the axis 12 , at least axially, and being kept apart from one another, bearing against the walls of the auxiliary frame 8, by an elastic element 14. The axis 12 can therefore move vertically in the slots 11. The ends of the axes 12 are further engaged in a pair of slots 15 formed in the main chassis 1. The slots 15 are slightly inclined in the direction of the penultimate roller 6. The discs 13 are preferably made of a Ferodo type material (Registered trademark) and their flat outer faces are directly applied against the auxiliary chassis 8.

La patin est en outre muni d'un moyen élastique non représenté s'opposant au basculement du châssis principal 1 sur le châssis auxiliaire 8. Ce moyen élastique peut être, par exemple, un ressort de torsion monté autour de l'axe 7 ou un ressort travaillant en traction entre les deux châssis.The skate is also provided with an elastic means not shown opposing the tilting of the main frame 1 on the auxiliary frame 8. This elastic means can be, for example, a torsion spring mounted around the axis 7 or a spring working in traction between the two frames.

Lors du basculement du châssis principal 1 autour de l'axe 7 de l'avant-dernière roulette, comme représenté à la figure 3, l'axe 12 des disques est entraîné vers le bas par les lumières 15 et guidé dans ce déplacement par les lumières 11.During the tilting of the main frame 1 around the axis 7 of the penultimate roller, as shown in Figure 3, the axis 12 of the discs is driven downwards by the slots 15 and guided in this movement by the lights 11.

Les disques de frein 13 viennent s'appliquer simultanément sur les deux roulettes arrière 6 et 10 et ils sont entraînés en rotation par ces roulettes. La forme conique des disques provoque l'écartement des disques par les roulettes et par conséquent le freinage par frottement des disques contre le châssis auxiliaire 8.The brake discs 13 are applied simultaneously on the two rear rollers 6 and 10 and they are rotated by these rollers. The conical shape of the discs causes the discs to spread apart by the rollers and consequently the friction braking of the discs against the auxiliary chassis 8.

Les lumières 15 pourraient être horizontales, mais leur inclinaison a pour effet d'augmenter la descente de l'axe 12 par l'effet de came qui s'ajoute à la descente des lumières 15.The lights 15 could be horizontal, but their inclination has the effect of increasing the descent of the axis 12 by the cam effect which is added to the descent of the lights 15.

Une variante d'exécution de cette première forme d'exécution est représentée à la figure 4. Cette variante ne diffère de la première forme d'exécution que par la forme du châssis principal 1' et le montage de la chaussure 4 sur ce châssis principal. La semelle de la chaussure est solidaire d'un bâti 16 articulé à l'avant du châssis 1' autour d'un axe transversal 17 et mobile verticalement à l'arrière où un ressort 18, ou autre élément élastique, est interposé entre le châssis 16 et la plateforme arrière du châssis 1'. Dans cette zone, le bâti 16 présente donc deux ailes parallèles venant de chaque côté du châssis 1'. L'ébat de la chaussure est limité, de chaque côté du châssis 1', par deux tétons 19 engagés chacun dans des lumières verticales 20 du bâti 16. Les lumières 20 sont à l'amplomb de l'axe de la roulette 6. Le châssis auxiliaire 8 et le frein sont identiques à ceux de la première forme d'exécution.An alternative embodiment of this first embodiment is shown in Figure 4. This variant differs from the first embodiment only in the shape of the main frame 1 'and the mounting of the shoe 4 on this main frame . The sole of the shoe is integral with a frame 16 articulated at the front of the chassis 1 'around a transverse axis 17 and movable vertically at the rear where a spring 18, or other elastic element, is interposed between the chassis 16 and the rear platform of the chassis 1 '. In this area, the frame 16 therefore has two parallel wings coming from each side of the frame 1 '. The framing of the shoe is limited, on each side of the chassis 1 ′, by two pins 19 each engaged in vertical slots 20 of the frame 16. The slots 20 are in line with the axis of the caster 6. The auxiliary chassis 8 and the brake are identical to those of the first embodiment.

Dans les exécutions décrites ci-dessus, la pression et les frottements de l'axe 12 sur le côté de la lumière 15 sont importants et peuvent poser à terme un problème d'usure. La forme d'exécution représentée à la figure 5 a pour but d'obvier à ce problème d'usure en remplaçant l'abaissement de l'axe 12 des disques de frein par effet de came par un système articulé de type pantographe. Dans cette deuxième forme d'exécution, un châssis auxiliaire 21, constitué de deux plaques parallèles découpées en forme d'anneau est articulé sur un châssis principal 22 autour d'un axe 23 situé entre l'avant-dernière roulette 6 et la dernière roulette 10, légèrement en-dessous de la droite joignant l'axe 24 de la roulette 6 et l'axe 25 de la roulette 10 et à égale distance de ces axes. Les plaques du châssis auxiliaire 21 sont articulées à l'extérieur du châssis principal 22. L'axe 12, des disques de frein 13 est situé au-dessus de l'axe 23, à la verticale de cet axe (le patin reposant sur un sol horizontal) et il est relié, d'une part, au bâti principal 22 par une première paire de biellettes 26 articulées à l'arrière du bâti principal 22 autour d'un axe 27 et, d'autre part, au châssis auxiliaire 21 par une paire de plateaux de frein 28 articulés sur le châssis auxiliaire 21 autour d'un axe 29 et correspondant mécaniquement à une seconde paire de biellettes. Les longueurs de toutes ces biellettes, mesurées entre leurs axes d'articulation, sont identiques, de telle sorte que l'axe 12 des disques est à la même distance des axes 27 et 29. La distance entre les axes 23 et 29 est également égale à la distance entre les axes 23 et 27, de telle sorte que les articulations constituent un pantographe et que l'axe 12 est toujours équidistant des axes 24 et 25 des roulettes. Les plateaux de frein 28, en aluminium, sont situés à l'intérieur du châssis auxiliaire 21, dans des découpes ovales 30 ménagées dans le châssis principal 22. La hauteur de ces découpes 30 est suffisante pour permettre le déplacement vertical des plateaux de frein 28. L'axe 12 des disques de frein est en outre soutenu par un ressort 31 s'appuyant sur une butée 32 montée sur l'axe 23. Le déplacement de l'axe 12 vers le haut est limité par une butée 33 fixée au châssis principal 22. Le basculement du châssis principal 22 sur l'avant-dernière roulette 6 a pour effet de déformer le pantographe formé par le système articulé, de telle sorte que l'axe 12 descend en direction de l'axe 23. Les disques de frein 13 sont alors entraînés par les roulettes 6 et 10 et sont appliqués contre les plateaux de frein 28.In the embodiments described above, the pressure and the friction of the axis 12 on the side of the lumen 15 are high and can eventually pose a wear problem. The embodiment shown in Figure 5 aims to obviate this wear problem by replacing the lowering of the axis 12 of the brake discs by cam effect by an articulated system of pantograph type. In this second embodiment, an auxiliary chassis 21, consisting of two parallel plates cut in the form of a ring, is articulated on a main chassis 22 around an axis 23 located between the penultimate caster 6 and the last caster 10, slightly below the straight line joining the axis 24 of the caster 6 and the axis 25 of the caster 10 and equidistant from these axes. The plates of the auxiliary chassis 21 are articulated outside the main chassis 22. The axis 12, of the brake discs 13 is located above the axis 23, vertical to this axis (the shoe resting on a horizontal floor) and it is connected, on the one hand, to the main frame 22 by a first pair of rods 26 articulated at the rear of the main frame 22 around an axis 27 and, on the other hand, to the auxiliary frame 21 by a pair of brake plates 28 articulated on the auxiliary chassis 21 around an axis 29 and corresponding mechanically to a second pair of rods. The lengths of all these links, measured between their articulation axes, are identical, so that the axis 12 of the discs is at the same distance from axes 27 and 29. The distance between axes 23 and 29 is also equal to the distance between axes 23 and 27, so that the joints constitute a pantograph and that the axis 12 is always equidistant from the axes 24 and 25 of the rollers. The brake plates 28, made of aluminum, are located inside the auxiliary chassis 21, in oval cutouts 30 made in the main chassis 22. The height of these cutouts 30 is sufficient to allow the vertical movement of the brake plates 28 The axis 12 of the brake discs is further supported by a spring 31 resting on a stop 32 mounted on the axis 23. The movement of the axis 12 upwards is limited by a stop 33 fixed to the chassis main 22. The tilting of the main chassis 22 on the penultimate roller 6 has the effect of deforming the pantograph formed by the articulated system, so that the axis 12 descends in the direction of the axis 23. The discs of brake 13 are then driven by the rollers 6 and 10 and are applied against the brake plates 28.

Les plateaux 28 descendant avec les disques 13, ils ne s'opposent pas à cette descente, contrairement à la première forme d'exécution dans laquelle les disques 13 doivent glisser sur le châssis auxiliaire.The plates 28 descending with the discs 13, they do not oppose this descent, unlike the first embodiment in which the discs 13 must slide on the auxiliary frame.

Selon la troisième forme d'exécution, représentée aux figures 6 et 7, la chaussure 4 est articulée sur un châssis principal 34 autour d'un axe 35 et un moyen élastique non représenté oppose une résistance à la rotation de la chaussure 4 autour de cet axe 35. La chaussure 4 pourrait toutefois être montée rigidement sur le châssis 34. Ce châssis 34 est constitué d'une pièce profilée en U dont les ailes sont dirigées vers le haut. Le fond de ce profil est découpé pour le passage des roulettes 5, 9 et 6. La roulette arrière 10 est montée à l'extrémité arrière d'un châssis auxiliaire 36 constitué de deux plaques parallèles articulées autour d'un axe 37 sur une pièce 38 en forme de chape dont le fond est situé en-dessous de l'axe 37. Cette chape 38 est, d'autre part, articulée sur le châssis principal 34 autour d'un axe 39 situé au même niveau que l'axe 37 et, comme lui, parallèle aux axes des roulettes. Les axes 37 et 39 sont situés juste au-dessus du fond de la chape 38, ce fond étant découpé pour le passage des roulettes 6 et 10. A l'intérieur de la chape 38 sont montés rotativement les disques de frein 13 autour d'un axe 40. Comme on peut le voir à la figure 7, la chape enveloppe les extrémités des châssis 34 et 36. De chaque côté de la chape 38 est monté un ressort 41 constitué d'une barre travaillant en flexion s'appuyant d'un côté sur un téton 42 du châssis principal 34 et, de l'autre côté, sur un plot 43 présentant plusieurs facettes permettant de régler la prétention du ressort 41. Dans sa zone médiane, le ressort s'appuie sur les extrémités des axes 37 et 39 avec une précontrainte ajustable au moyen du plot 43. Ce réglage permet de s'affranchir de la contrainte d'avoir le poids du corps sur ou en avant de l'axe de l'avant dernière roulette en l'équilibrant par la réaction d'un ressort taré en fonction du poids de l'utilisateur.According to the third embodiment, shown in Figures 6 and 7, the shoe 4 is articulated on a main frame 34 about an axis 35 and an elastic means not shown opposes resistance to the rotation of the shoe 4 around this axis 35. The shoe 4 could however be rigidly mounted on the chassis 34. This chassis 34 consists of a U-shaped part, the wings of which are directed upwards. The bottom of this profile is cut out for the passage of the rollers 5, 9 and 6. The rear caster 10 is mounted at the rear end of an auxiliary frame 36 consisting of two parallel plates articulated around an axis 37 on a part 38 in the form of a yoke whose bottom is located below the axis 37. This yoke 38 is, on the other hand, articulated on the main frame 34 around an axis 39 located at the same level as the axis 37 and, like him, parallel to the axes of the rollers. The axes 37 and 39 are located just above the bottom of the yoke 38, this bottom being cut out for the passage of the rollers 6 and 10. Inside the yoke 38 are rotatably mounted the brake discs 13 around an axis 40. As can be seen in FIG. 7, the yoke envelops the ends of the frames 34 and 36. On each side of the yoke 38 is mounted a spring 41 consisting of a bar working in bending leaning on one side on a stud 42 of the main frame 34 and, on the other side, on a stud 43 having several facets making it possible to adjust the pretension of the spring 41. In its median zone, the spring is supported on the ends of the axes 37 and 39 with an adjustable preload by means of the stud 43. This adjustment makes it possible to overcome the constraint of having the body weight on or in front of the axis of the penultimate caster by balancing it by the reaction a spring calibrated according to the weight of the user.

Au repos, les ressorts 41 repoussent donc la chape 38 vers le haut, ce mouvement étant limité par la venue en butée des extrémités des châssis 34 et 36 contre le fond de la chape 38.At rest, the springs 41 therefore push the yoke 38 upwards, this movement being limited by the abutment of the ends of the frames 34 and 36 against the bottom of the yoke 38.

Lors du basculement du châssis principal 34 autour de la roulette 6, la chape 38 est tirée vers le bas par l'axe 39 en fléchissant les ressorts 41 et les disques de frein 13 sont appliqués sur les roues 6 et 10 et contre la chape 38 qui constitue la partie fixe du frein à disques. En s'appuyant sur l'avant-dernière roulette 6, les disques 13 entraînent l'axe 37 en descente et la pression des disques 13 sur les roulettes 6 et 10 s'équilibre d'elle-même.During the tilting of the main frame 34 around the caster 6, the yoke 38 is pulled down by the pin 39 by bending the springs 41 and the brake discs 13 are applied to the wheels 6 and 10 and against the yoke 38 which constitutes the fixed part of the disc brake. By relying on the penultimate roller 6, the discs 13 drive the axis 37 downward and the pressure of the discs 13 on the rollers 6 and 10 balances itself.

Dans une variante d'exécution dans laquelle la chaussure est fixée rigidement au châssis principal 34, les ressorts 41 pourraient être remplacés par un ressort de traction entre la chaussure et l'axe 40 des disques de frein.In an alternative embodiment in which the shoe is rigidly fixed to the main chassis 34, the springs 41 could be replaced by a tension spring between the shoe and the axis 40 of the brake discs.

La quatrième forme d'exécution, représentée aux figures 8 et 9, est dérivée de la forme d'exécution précédente. La chaussure 4 est montée sur un châssis principal 44 constitué d'un profil en U dans lequel sont articulées les roulettes 5, 9, 6. La roulette arrière 10 est montée à l'extrémité arrière d'un châssis auxiliaire 45 formé de deux plaques parallèles disposées de chaque côté du châssis principal 44 et articulées sur ce châssis principal autour d'un axe 46. Dans cet axe 46 est vissée, par le bas, une barre verticale 47 s'étendant dans le plan médian du châssis et dont l'extrémité supérieure est vissée dans un axe transversal 48 à chacune des extrémités duquel est fixé perpendiculairement un plateau circulaire 49 dont le diamètre correspond au diamètre des disques de frein 13 montés libre en rotation sur l'axe 48 entre les plateaux 49. Les plateaux 49 sont situés entre les plaques du châssis auxiliaire 45, dans le même plan que les ailes du châssis principal 44 qui présentent à cet effet un dégagement 51. On retrouve les ressorts 41 et les tétons 42, l'extrémité postérieure des ressorts 41 s'appuyant sur des tétons 50 du châssis auxiliaire 45. Les ressorts 41 traversent en outre l'axe 46.The fourth embodiment, shown in Figures 8 and 9, is derived from the previous embodiment. The shoe 4 is mounted on a main chassis 44 consisting of a U-shaped profile in which the rollers 5, 9, 6 are articulated. The rear caster 10 is mounted at the rear end of an auxiliary chassis 45 formed by two plates parallels arranged on each side of the main chassis 44 and articulated on this main chassis around an axis 46. In this axis 46 is screwed, from below, a vertical bar 47 extending in the median plane of the chassis and whose upper end is screwed in a transverse axis 48 at each end of which is fixed perpendicularly a circular plate 49 whose diameter corresponds to the diameter of the brake discs 13 mounted free in rotation on the axis 48 between the plates 49. The plates 49 are located between the plates of the auxiliary chassis 45, in the same plane as the wings of the main chassis 44 which have a clearance 51 for this purpose. We find the springs 41 and the studs 42, the rear end of the springs 41 resting on studs 50 of the auxiliary chassis 45. The springs 41 also pass through axis 46.

Lors du basculement du châssis principal 44 autour de la roulette 6, comme représenté à la figure 9, l'axe 46 est entraîné en direction du sol et les disques de frein 13 viennent en appui contre les roulettes 6 et 10 et sont appliqués contre les disques fixes 49.During the tilting of the main chassis 44 around the caster 6, as shown in FIG. 9, the axis 46 is driven towards the ground and the brake discs 13 come to bear against the casters 6 and 10 and are applied against the fixed discs 49.

Par sa partie vissée dans l'axe 48, la barre 47 permet en outre d'ajuster la position des disques de frein en fonction du diamètre des roulettes utilisées.By its part screwed in the axis 48, the bar 47 also makes it possible to adjust the position of the brake discs as a function of the diameter of the rollers used.
