Abstract

The in-line roller skate has a frame (1) made from two parallel vertical flanges with four or more rollers (4-7) between them. The axles of the rollers lie perpendicular to the flanges. The axles of the two middle rollers (5,6) are adjustable in vertical slots (9,11) in the flanges by two auxiliary plates (12) with oblique slots. The two auxiliary plates can be moved horizontally relative to the flanges and have lower edges (12a,13a) which curve under the edges of the flanges. After adjustment, they are locked in place by fixings (19). The oblique slots in the additional plates are basically kidney-shaped, and have two rounded ends set at different levels. In addition the two plates are joined rigidly together by a cross-piece passing under the skate.

Description

La présente invention a pour objet un patin à roulettes en ligne comprenant un châssis présentant deux ailes parallèles et équipées d'au moins quatre roulettes dont les axes sont perpendiculaires auxdites ailes et des moyens permettant de modifier le niveau des axes des roulettes centrales relativement au niveau des axes des autres roulettes, ces moyens comprenant, d'une part, des lumières verticales dans les ailes du châssis pour le passage des axes des roulettes à déplacer et, d'autre part, des moyens de positionnement de ces axes dans lesdites lumières.The present invention relates to an inline roller skate comprising a chassis having two parallel wings and equipped with at least four casters whose axes are perpendicular to said wings and means making it possible to modify the level of the axes of the central rollers relatively to the level axes of the other rollers, these means comprising, on the one hand, vertical slots in the wings of the chassis for the passage of the axes of the rollers to be moved and, on the other hand, means for positioning these axes in said slots.

L'alignement des axes des roulettes, dans un patin à roulettes en ligne, rend difficile un changement brusque de direction. D'autre part, beaucoup de patineurs sportifs désirent disposer de patins aussi bien aptes au patinage de vitesse qu'au slalom.Aligning the axes of the rollers in an inline skate makes it difficult to change direction abruptly. On the other hand, many sports skaters want to have skates as well suited to speed skating as to slalom.

A cet effet, il a déjà été proposé des patins dans lesquels les roulettes centrales peuvent être abaissées relativement aux autres roulettes de telle sorte que lorsque le patineur est en appui sur les deux roulettes centrales, proches l'une de l'autre, il peut effectuer très facilement un changement de direction proche d'un pivotement.To this end, skates have already been proposed in which the central rollers can be lowered relative to the other rollers so that when the skater is resting on the two central rollers, close to each other, he can very easily make a change of direction close to a pivot.

Une telle solution a déjà été proposée dans le document DE 29 42 969 pour un patin à trois roulettes. L'appui sur une seule roulette centrale nécessite toutefois un grand équilibre.Such a solution has already been proposed in document DE 29 42 969 for a three-roller skate. However, pressing on a single central caster requires great balance.

Dans le document US 4 909 523, il est proposé d'utiliser les cales nécessaires entre le moyeu des roulettes et le châssis. Les axes des roulettes traversent ces cales par des trous excentrés relativement à deux lumières verticales prévues dans le châssis, de telle sorte que le renversement de 180° de ces cales permet d'obtenir deux positions des roulettes de hauteurs différentes. Les axes des roulettes sont ainsi solidement fixés de façon très sûre, mais la modification du niveau des roulettes nécessite un démontage complet des roulettes, opération longue et fastidieuse, qui s'accompagne du risque de perdre des composants.In document US 4,909,523, it is proposed to use the necessary shims between the hub of the rollers and the chassis. The axes of the rollers pass through these shims through eccentric holes relative to two lumens vertical provided in the chassis, so that the 180 ° reversal of these wedges allows to obtain two positions of the casters of different heights. The axes of the rollers are thus securely fixed in a very secure manner, but the modification of the level of the rollers requires a complete disassembly of the rollers, a long and tedious operation, which is accompanied by the risk of losing components.

Le document EP 0 677 309 propose une construction obviant à l'inconvénient susmentionné. Dans ce patin, les deux roulettes centrales sont portées par un bâti auxiliaire pouvant être fixé à différents niveaux en un point situé entre les deux roulettes centrales. Lorsque les deux roulettes centrales sont en position basse, l'appui sur le sol a lieu souvent sur une seule de ces roulettes centrales et la fixation du bâti auxiliaire est alors soumise à un couple très élevé, ce qui nécessite une fixation très ferme, notamment par serrage, du bâti auxiliaire. Ce problème se retrouve dans le patin décrit dans le document WO 94/26367, dans lequel il est prévu de modifier le niveau du bâti auxiliaire au moyen d'un excentrique bloqué par un simple levier-came.Document EP 0 677 309 proposes a construction which overcomes the aforementioned drawback. In this skate, the two central rollers are carried by an auxiliary frame which can be fixed at different levels at a point located between the two central rollers. When the two central rollers are in the low position, the support on the ground often takes place on only one of these central rollers and the fixing of the auxiliary frame is then subjected to a very high torque, which requires a very firm fixing, in particular by clamping, of the auxiliary frame. This problem is found in the shoe described in document WO 94/26367, in which it is planned to modify the level of the auxiliary frame by means of an eccentric blocked by a simple cam lever.

Le document WO 92/10251 propose plusieurs solutions pour modifier la hauteur des deux roulettes centrales relativement aux autres roulettes. L'une de ces solutions consiste à monter les deux roulettes centrales dans un bâti auxiliaire monté à l'intérieur d'un châssis principal en U et présentant, à son extrémité supérieure, une rampe oblique coopérant avec un coin déplaçable transversalement au moyen d'une vis. Une autre solution consiste à monter les axes des deux roulettes centrales excentriquement sur des plots cylindriques dont la rotation permet de modifier la hauteur des roulettes centrales. Chacune des roulettes est donc réglée individuellement et il convient donc de prendre garde que les roulettes soient réglées de façon identique.Document WO 92/10251 proposes several solutions for modifying the height of the two central rollers relative to the other rollers. One of these solutions consists in mounting the two central rollers in an auxiliary frame mounted inside a main U-shaped chassis and having, at its upper end, an oblique ramp cooperating with a wedge movable transversely by means of a screw. Another solution consists in mounting the axes of the two central rollers eccentrically on cylindrical studs whose rotation makes it possible to modify the height of the rollers power stations. Each of the rollers is therefore adjusted individually and care should therefore be taken that the rollers are adjusted identically.

Du brevet US 3,880,441 on connaît également un patin dans lequel les axes des roulettes d'extrémités sont montés dans des lumières obliques permettant de les surélever relativement aux roulettes centrales, ce qui conduit au-même résultat que dans les cas cités précédemment.From patent US 3,880,441 there is also known a shoe in which the axes of the end rollers are mounted in oblique slots allowing them to be raised relative to the central rollers, which leads to the same result as in the cases mentioned above.

La présente invention a pour but de réaliser un patin à roulettes en ligne dont le niveau des roulettes centrales ou des autres roulettes peut être modifié très rapidement, de manière simultanée et identique, par des moyens simples et robustes, insensibles aux effets de torsion.The object of the present invention is to produce an inline roller skate, the level of the central rollers or of the other rollers can be changed very quickly, simultaneously and identically, by simple and robust means, insensitive to the effects of torsion.

Le patin à roulettes selon l'invention est caractérisé en ce que les moyens de positionnement des axes des roulettes à déplacer sont constitués de deux plaques auxiliaires parallèles aux ailes du châssis, déplaçables longitudinalement sur le châssis et dont les bords inférieurs sont coudés de manière à s'appuyer sur les bords inférieurs des ailes du châssis, les axes des roulettes à déplacer traversant lesdites plaques à travers des lumières présentant une orientation générale oblique relativement aux lumières du châssis et de largeur au moins égale au diamètre des axes des roulettes à déplacer, des moyens de blocage étant prévus pour fixer lesdites plaques dans la position longitudinale choisie.The roller skate according to the invention is characterized in that the means for positioning the axes of the rollers to be moved consist of two auxiliary plates parallel to the wings of the chassis, movable longitudinally on the chassis and whose lower edges are bent so as to lean on the lower edges of the wings of the chassis, the axes of the rollers to be moved passing through said plates through openings having a generally oblique orientation relative to the lights of the chassis and of width at least equal to the diameter of the axes of the rollers to be moved, blocking means being provided for fixing said plates in the longitudinal position chosen.

Les plaques auxiliaires peuvent positionner, soit les axes des roulettes centrales, soit les axes des autres roulettes, en particulier les roulettes d'extrémités dans un patin à quatre roulettes.The auxiliary plates can position either the axes of the central rollers or the axes of the others casters, in particular the end casters in a four-roller skate.

Les lumières des plaques auxiliaires peuvent présenter différentes formes. Elles peuvent avantageusement être coudées de manière à présenter deux positions discrètes, respectivement haute et basse. Elles peuvent être tout simplement droites et obliques de manière à permettre un réglage continu entre deux positions extrêmes. Dans tous les cas, les efforts exercés par les axes des roulettes sur les plaques auxiliaires sont repris par le châssis, par l'appui des bords coudés des plaques auxiliaires.The lights of the auxiliary plates can have different shapes. They can advantageously be bent so as to have two discrete positions, respectively high and low. They can simply be straight and oblique so as to allow continuous adjustment between two extreme positions. In all cases, the forces exerted by the axes of the rollers on the auxiliary plates are taken up by the chassis, by the support of the bent edges of the auxiliary plates.

Les moyens de blocage peuvent être tout simplement constitués par les écrous ou les vis destinés à plaquer les ailes du châssis contre les moyeux des roulettes.The locking means may simply consist of the nuts or the screws intended to press the wings of the chassis against the hubs of the rollers.

De manière à faciliter encore davantage le réglage, les deux plaques auxiliaires peuvent être reliées rigidement entre elles, par exemple par leurs bords inférieurs ou par leurs bords supérieurs.In order to further facilitate adjustment, the two auxiliary plates can be rigidly connected together, for example by their lower edges or by their upper edges.

Il convient de relever que les lumières du châssis peuvent déboucher sur le bord inférieur des ailes de celui-ci de manière à former des encoches facilitant le montage des roulettes centrales.It should be noted that the lights of the chassis can lead to the lower edge of the wings of the latter so as to form notches facilitating the mounting of the central rollers.

Ces modes d'exécution, ainsi que d'autres caractéristiques de l'invention, font l'objet des revendications dépendantes.These embodiments, as well as other features of the invention, are the subject of the dependent claims.

Le dessin représente, à titre d'exemple, un mode d'exécution de l'invention.The drawing represents, by way of example, an embodiment of the invention.

La figure 1 représente un patin à quatre roulettes en ligne avec les axes de toutes les roulettes dans le même plan.FIG. 1 represents a skate with four rollers in line with the axes of all the rollers in the same plane.

La figure 2 est une vue en coupe selon II-II de la figure 1.Figure 2 is a sectional view along II-II of Figure 1.

La figure 3 représente le même patin avec les deux roulettes centrales en position abaissée relativement aux autres roulettes.Figure 3 shows the same shoe with the two central rollers in the lowered position relative to the other rollers.

La figure 4 est une vue en coupe selon IV-IV de la figure 3.FIG. 4 is a sectional view along IV-IV of FIG. 3.

Le patin représenté est constitué essentiellement d'un châssis principal 1 présentant un profil en U interrompu dans sa partie centrale de manière à former deux plates-formes 2 et 3 destinées à supporter une chaussure non représentée. Ce châssis peut être en métal, tel que de l'aluminium ou en plastique dur. Entre les ailes 1a et 1b du châssis 1 sont montées quatre roulettes en ligne 4, 5, 6, 7. Les axes des roulettes d'extrémité 4 et 7 occupent une position fixe dans le châssis 1. Par contre, les axes des roulettes centrales 5 et 6, tels que l'axe 8 de la roulette 6 visible à la figure 2, traversent les ailes 1a et 1b du châssis 1 à travers des lumières verticales 9 et 10, respectivement 11, de largeur égale au diamètre des axes des roulettes. Ces axes traversent en outre deux plaques latérales auxiliaires 12 et 13 à travers des lumières 14 et 15 présentant une forme générale de haricot dont les extrémités sont situées à des hauteurs différentes relativement au sol 16 et sont en forme de logements arrondis 17 et 18 de rayon correspondant au rayon des axes 8 des roulettes, logements dans lesquels les axes des roulettes centrales sont retenus latéralement dans la direction de roulement. Les axes 8 des roulettes centrale 5 et 6 peuvent toutefois se déplacer d'une extrémité à l'autre des lumières 14 et 15. Les bords inférieurs 12a et 13a des plaques latérales 12 et 13 sont rectilignes et coudés vers l'intérieur de manière à venir s'appuyer sur les bords inférieurs rectilignes des ailes 1a et 1b du châssis. Les roulettes sont des roulettes conventionnelles montées sur roulements à billes dont la bague intérieure est fixée entre les ailes 1a et 1b du châssis, par exemple comme représenté dans le document WO 94/26367. L'une des extrémités de l'axe 8 est donc constituée d'un écrou ou d'une vis 19 permettant de serrer la bague intérieure des roulements des roulettes entre les ailes 1a et 1b du châssis, les plaques 12 et 13 étant, par conséquent, également serrées contre le châssis.The shoe shown consists essentially of a main frame 1 having a U-shaped profile interrupted in its central part so as to form two platforms 2 and 3 intended to support a shoe not shown. This chassis can be made of metal, such as aluminum or hard plastic. Between the wings 1a and 1b of the chassis 1 are mounted four in-line rollers 4, 5, 6, 7. The axes of the end rollers 4 and 7 occupy a fixed position in the chassis 1. On the other hand, the axes of the central rollers 5 and 6, such as the axis 8 of the caster 6 visible in FIG. 2, pass through the wings 1a and 1b of the chassis 1 through vertical slots 9 and 10, respectively 11, of width equal to the diameter of the axes of the caster wheels . These axes also pass through two auxiliary side plates 12 and 13 through slots 14 and 15 having a general bean shape, the ends of which are situated at different heights relative to the ground 16 and are in the form of rounded housings 17 and 18 of radius corresponding to the radius of the axes 8 of the rollers, housings in which the axes central rollers are retained laterally in the direction of travel. The axes 8 of the central rollers 5 and 6 can however move from one end to the other of the slots 14 and 15. The lower edges 12a and 13a of the side plates 12 and 13 are rectilinear and bent inwards so as to come to rest on the rectilinear lower edges of the wings 1a and 1b of the chassis. The rollers are conventional rollers mounted on ball bearings, the inner ring of which is fixed between the wings 1a and 1b of the chassis, for example as shown in document WO 94/26367. One of the ends of the axis 8 therefore consists of a nut or a screw 19 making it possible to tighten the inner ring of the roller bearings between the wings 1a and 1b of the chassis, the plates 12 and 13 being, by Therefore, also tight against the chassis.

Dans la position des plaques 12 et 13 représentée à la figure 1, les extrémités 18 des lumières 14 et 15 des plaques auxiliaires coïncident avec les extrémités supérieures des lumières 9, 10, 11 du châssis et les axes des roulettes centrales 5 et 6 sont dans le même plan que les axes des roulettes 4 et 7. Les quatre roulettes étant identiques, le patin est en contact par ses quatre roulettes sur un seul plan.In the position of the plates 12 and 13 shown in FIG. 1, the ends 18 of the slots 14 and 15 of the auxiliary plates coincide with the upper ends of the slots 9, 10, 11 of the chassis and the axes of the central rollers 5 and 6 are in the same plane as the axes of the rollers 4 and 7. The four rollers being identical, the shoe is in contact by its four rollers on a single plane.

Pour modifier la hauteur des roulettes centrales 5 et 6 relativement aux roulettes 4 et 7, il suffit de desserrer les vis 19 des axes des roulettes 5 et 6 de manière à libérer ces axes et les plaques auxiliaires 12 et 13, puis de faire coulisser les plaques 12 et 13 dans le sens de la flèche indiquée à la figure 3 pour amener les axes des roulettes 5 et 6 à l'autre extrémité des lumières 14 et 15, c'est-à-dire dans les logements 17, les axes des roulettes se déplaçant verticalement dans les lumières 9 à 11. Lors de ce déplacement, les plaques 12 et 13 sont guidées par leurs rebords coudés 12a, 13a, de telle sorte que le changement de niveau des roulettes centrales 5 et 6 s'effectue par un simple coulissement des plaques 12 et 13. Il suffit ensuite de resserrer les vis 19 des axes des roulettes. Le retour à la position représentée à la figure 1 s'opère en faisant coulisser les plaques 12 et 13 dans l'autre sens.To modify the height of the central rollers 5 and 6 relative to the rollers 4 and 7, it is sufficient to loosen the screws 19 of the axes of the rollers 5 and 6 so as to release these axes and the auxiliary plates 12 and 13, then to slide the plates 12 and 13 in the direction of the arrow indicated in FIG. 3 to bring the axes of the rollers 5 and 6 to the other end of the slots 14 and 15, that is to say in the housings 17, the axes of the rollers moving vertically in the slots 9 to 11. During this movement, the plates 12 and 13 are guided by their bent edges 12a, 13a, so that the level change of the central rollers 5 and 6 s' performs by simply sliding the plates 12 and 13. It then suffices to tighten the screws 19 of the axes of the rollers. The return to the position shown in Figure 1 takes place by sliding the plates 12 and 13 in the other direction.

L'entraînement simultané des plaques 12 et 13 peut se faire en saisissant celles-ci entre le pouce et les doigts d'une main. Il est toutefois possible de faciliter le déplacement simultané des plaques 12 et 13 en reliant celles-ci, soit par le bas, entre les roulettes 5 et 6, comme représenté en traits mixtes 20 aux figures 2 et 4, soit par le haut, entre les plates-formes 2 et 3 du châssis.The simultaneous driving of the plates 12 and 13 can be done by grasping them between the thumb and the fingers of one hand. It is however possible to facilitate the simultaneous movement of the plates 12 and 13 by connecting them, either from the bottom, between the rollers 5 and 6, as shown in phantom 20 in Figures 2 and 4, or from the top, between platforms 2 and 3 of the chassis.

L'invention n'est en outre pas limitée au mode d'exécution représenté. Les plaques 12 et 13 pourraient être disposées à l'intérieur du châssis 1. Les lumières 14 et 15 des plaques auxiliaires pourraient présenter une forme différente. En particulier, ces lumières pourraient être de simples lumières rectilignes obliques dont le croisement avec les lumières verticales du châssis 1 permettrait un réglage continu de la hauteur des roulettes centrales 5 et 6. Dans ce cas, il pourrait être utile de prévoir des moyens additionnels de blocage des plaques 12 et 13 sur le châssis 1.The invention is also not limited to the embodiment shown. The plates 12 and 13 could be arranged inside the chassis 1. The slots 14 and 15 of the auxiliary plates could have a different shape. In particular, these lights could be simple oblique rectilinear lights whose crossing with the vertical lights of the chassis 1 would allow a continuous adjustment of the height of the central rollers 5 and 6. In this case, it could be useful to provide additional means of blocking of plates 12 and 13 on chassis 1.
