Abstract

The roller skate consists of a main frame (1) with two side plates, between which the rollers (2, 3, 4, 5) are fitted, and an auxiliary inverted U-shaped frame (8) on which the boot is mounted, the auxiliary frame being pivoted to the main one about an axis parallel to the axes of the wheels. The auxiliary frame is pivoted to the main frame by means of two stepped discs (12) which are fixed to the outer surfaces of the main frame. The discs and matching apertures in the auxiliary frame are mounted on the main frame with their smaller sides facing inwards. Each of the discs is fastened in place by a roller axle nut and an auxiliary screw.

Description

La présente invention a pour objet un patin à roulettes en ligne comprenant un châssis principal présentant deux plaques latérales parallèles entre lesquelles sont montées au moins deux roulettes et un châssis auxiliaire profilé en U, chevauchant le châssis principal et articulé sur ce châssis principal autour d'un axe parallèle aux axes des roulettes et portant une chaussure.The present invention relates to a roller skate in line comprising a main chassis presenting two parallel side plates between which are mounted at least two casters and a chassis U-shaped auxiliary, overlapping the chassis main and articulated on this main chassis around an axis parallel to the axes of the rollers and bearing a shoe.

Du brevet GB 2 160 780, on connaít un patin à deux roulettes en lignes montées aux extrémités d'un châssis principal au milieu duquel est articulé un châssis auxiliaire portant la chaussure. Un patin analogue est également connu du brevet US 5,135,244.From GB patent 2 160 780, we know a pair of skates in-line casters mounted at the ends of a chassis main in the middle of which is articulated a chassis auxiliary carrying the shoe. A similar pad is also known from US Patent 5,135,244.

Le demandeur a en outre réalisé un patin en ligne à quatre roulettes dont le châssis auxiliaire portant la chaussure présente un profil en U qui chevauche le châssis principal et qui est articulé sur ce dernier autour d'un axe situé entre les deux roulettes avant ou juste au-dessus de l'axe de la deuxième roulette à compter de la roulette avant. Un tel patin est décrit dans la demande de brevet FR 2.744.033 au nom du demandeur.The applicant also carried out an inline skate at four casters including the auxiliary chassis carrying the shoe has a U-shaped profile that overlaps the main chassis and which is articulated on the latter around an axis located between the two front casters or just above the axis of the second wheel at count from front roulette. Such a skate is described in patent application FR 2,744,033 in the name of applicant.

Pour des raisons évidente de poids, l'épaisseur des plaques verticales parallèles du châssis principal entre lesquelles sont montées les roulettes, est limitée, une rigidité suffisante de ces plaques, généralement réalisées en alliage d'aluminium, étant obtenue avec une épaisseur de quelques millimètres déjà. L'articulation du châssis auxiliaire sur le châssis principal s'effectue au moyen d'une vis et d'un écrou tubulaire traversant les plaques du châssis principal et dont la longueur est telle qu'elle supporte le châssis principal et le châssis auxiliaire. L'espace entre les roulettes et les parois intérieures du châssis principal est faible, ce qui laisse très peu de place pour la tête de l'écrou tubulaire. Pour parvenir à réaliser l'articulation, il est par conséquent nécessaire non seulement d'utiliser une tête d'écrou de hauteur aussi faible que possible, mais encore de noyer partiellement cette tête dans la paroi du châssis principal. Ces deux mesures contribuent à affaiblir l'articulation.For obvious weight reasons, the thickness of the parallel vertical plates of the main chassis between which the casters are mounted, is limited, sufficient rigidity of these plates, generally made of aluminum alloy, being obtained with a thickness of a few millimeters already. The articulation of the auxiliary chassis on the main chassis is carried out by means of a screw and a tubular nut passing through the chassis plates main and whose length is such that it supports the main chassis and the auxiliary chassis. The space between the rollers and the interior walls of the main chassis is weak, which leaves very little space for the head of the tubular nut. For achieve the joint it is by therefore necessary not only to use a head nut as low as possible but still to partially drown this head in the wall of the main chassis. These two measures contribute to weaken the joint.

L'invention a pour but de réaliser une articulation qui ne soit plus soumise à la contrainte de l'espace intérieur entre les roulettes et le châssis principal.The object of the invention is to produce a joint which no longer be constrained by space interior between the casters and the main chassis.

La construction selon l'invention est caractérisée en ce que le châssis auxiliaire est articulé autour de deux disques fixés sur les faces extérieures du châssis principal.The construction according to the invention is characterized in what the auxiliary chassis is hinged around two discs attached to the outside of the chassis main.

Non seulement aucune pièce ne fait plus saillie à l'intérieur du châssis principal, mais l'utilisation d'un disque permet d'agrandir la surface portante et par conséquent de réduire les efforts sur le pivot ainsi formé.Not only does no part project more inside the main chassis but use of a disc enlarges the bearing surface and consequently to reduce the efforts on the pivot thus formed.

De manière à assurer également la retenue latérale du châssis auxiliaire, les disques présentent de préférence deux portées cylindriques de diamètres différents et le châssis auxiliaire présente des découpes auxiliaires circulaires présentant chacune deux diamètres correspondant respectivement à chacun des diamètres des portées des disques, le diamètre le plus petit étant situé du côté intérieur du châssis auxiliaire. Tout écartement du châssis auxiliaire est ainsi empêché.So as to also ensure lateral retention of the auxiliary chassis, the discs have preferably two cylindrical bearings of diameters different and the auxiliary chassis has auxiliary circular cutouts each having two diameters corresponding respectively to each of the diameters of the spans of the discs, the diameter smaller being located on the inside of the chassis auxiliary. Any spacing in the auxiliary chassis is thus prevented.

Selon un mode d'exécution préféré de l'invention, le patin comporte quatre roulettes et les disques sont fixés, d'une part, par un écrou de roulette et, d'autre part, par une vis auxiliaire.According to a preferred embodiment of the invention, the skate has four casters and the discs are fixed, on the one hand, by a wheel nut and, on the other part, by an auxiliary screw.

En prévoyant sur le châssis principal plusieurs trous taraudés situés sur un arc de cercle centré sur l'axe de la roulette dont les écrous retiennent les disques, il est possible de modifier la position, soit vers l'avant, soit vers l'arrière, des disques et par conséquent de modifier la position de l'articulation du châssis auxiliaire dans la direction longitudinale du patin.By providing several holes on the main chassis tapped located on an arc centered on the axis of roulette whose nuts retain the discs, it is possible to change the position, either towards front, or back, discs and by consequently to modify the position of the articulation of the auxiliary chassis in the longitudinal direction of the skate.

Le dessin annexé représente, à titre d'exemple, un mode d'exécution du patin selon l'invention.The accompanying drawing shows, by way of example, a mode of execution of the skate according to the invention.

La figure 1 est une vue latérale du patin dont la chaussure a été partiellement représentée et les roulettes schématiquement représentées.Figure 1 is a side view of the skate whose shoe has been partially represented and the wheels shown schematically.

La figure 2 est une demi coupe transversale selon II-II de la figure 1. Figure 2 is a half cross section along II-II of figure 1.

La figure 3 représente une variante d'exécution.Figure 3 shows an alternative embodiment.

Le patin représenté comprend un châssis principal 1 portant quatre roulettes en ligne 2, 3, 4, 5 dont les arbres fixes en rotation sont fixés au moyen d'écrous 6 vissés aux extrémités filetées des arbres 7.The shoe shown comprises a main chassis 1 carrying four rollers in line 2, 3, 4, 5 whose fixed rotating shafts are fixed by means of nuts 6 screwed to the threaded ends of the shafts 7.

Sur le châssis principal 1 est monté un châssis auxiliaire 8 présentant deux plates-formes 9 et 10 sur lesquelles est fixée une chaussure 11.On the main chassis 1 is mounted a chassis auxiliary 8 having two platforms 9 and 10 on which is attached a shoe 11.

Le châssis principal 1, en une seule pièce, présente deux ailes verticales parallèles dont l'une 1a est visible à la figure 2. Ces ailes sont reliées par des entretoises telles que l'entretoise 1b dont une portion est visible à la figure 2. Le châssis auxiliaire 8 présente, au moins dans la zone des plates-formes 9 et 10, un profil en U chevauchant le châssis principal 1 comme ceci est visible à la figure 2 et articulé sur le châssis principal 1 autour d'un axe situé au-dessus de l'axe de la roulette 3, à la verticale de cet axe. L'articulation est réalisé au moyens de disques 12 dont l'épaisseur est égale à l'épaisseur des ailes du châssis auxiliaire 8. Ces disques 12 sont fixés, d'une part, par les écrous 6 de l'arbre 7 de la roue 3 et, d'autre part, par des vis 13 vissées dans le châssis principal 1. Les disques 12 présentent deux diamètres différents définissant deux portées cylindriques 14 et 15, la portée cylindrique 14 de plus petit diamètre étant située du côté du châssis principal 1. Les disques 12 viennent s'emboíter dans des découpes circulaires 16 des ailes du châssis auxiliaire 8, découpes qui présentent deux diamètres correspondant respectivement aux diamètres 14 et 15. Les disques 12 servent donc de pivots au châssis auxiliaire 8 en empêchant en outre l'écartement de ce châssis.The main frame 1, in one piece, has two parallel vertical flanges, one of which 1a is visible in Figure 2. These wings are connected by spacers such as spacer 1b, a portion is visible in Figure 2 The auxiliary chassis 8 has, at least in the area of the platforms 9 and 10, a U-shaped profile overlapping the main chassis 1 as can be seen in FIG. 2 and articulated on the main chassis 1 around an axis located above the axis of the caster 3, vertical to this axis. The articulation is produced by means of discs 12 whose thickness is equal to the thickness of the wings of the auxiliary chassis 8. These discs 12 are fixed, on the one hand, by the nuts 6 of the shaft 7 of the wheel 3 and, on the other hand, by screws 13 screwed into the main chassis 1. The discs 12 have two different diameters defining two cylindrical bearings 14 and 15, the cylindrical bearing 14 of smaller diameter being located on the side of the main chassis 1 The discs 12 fit into circular cutouts 16 of the wings of the auxiliary frame 8, cutouts which have two diameters corresponding respectively to diameters 14 and 15. The discs 12 therefore serve as pivots to the auxiliary frame 8, further preventing the spacing of this chassis.

Une possibilité de réglage peut être obtenue en prévoyant des trous supplémentaires, tels que les trous 17 et 18, dans le châssis principal. Ces trous taraudés sont situés sur un arc de cercle centré sur l'axe géométrique de l'arbre 7 et passant par le centre du trou dans lequel est vissée la vis 13. Cette vis 13 peut donc être vissée dans le trou 17 ou 18, ce qui correspond respectivement à un déplacement vers l'arrière et vers l'avant des disques 12, c'est-à-dire du châssis auxiliaire 8. On obtient ainsi une possibilité de réglage de la position du châssis auxiliaire relativement au châssis principal et de son axe de pivotement.An adjustment option can be obtained by providing for additional holes, such as holes 17 and 18, in the main chassis. These tapped holes are located on an arc centered on the axis geometric of tree 7 and passing through the center of hole in which screw 13 is screwed. This screw 13 can therefore be screwed into hole 17 or 18, which corresponds respectively to a displacement towards back and forward of discs 12, i.e. of the auxiliary chassis 8. This gives a possibility of adjusting the chassis position auxiliary relative to the main chassis and its pivot axis.

Le patin est en outre bien entendu équipé d'un support élastique en arrière de l'articulation 12. Ce support élastique peut être réalisé, par exemple, comme représenté dans l'un ou l'autre mode d'exécution décrit dans la demande de brevet FR 96 01242.The skate is of course also equipped with a support elastic behind the joint 12. This support elastic can be achieved, for example, as shown in either embodiment described in patent application FR 96 01 242.

De manière à augmenter la résistance du châssis auxiliaire 8 à la pression verticale dans la partie située en dessous des découpes circulaires 16 sans augmenter la hauteur du châssis auxiliaire à cet endroit, un allongement vers le bas pouvant devenir gênant lors du patinage, le lamage formé dans les découpes 16 par ses deux diamètres différents peut être limité angulairement. Une telle exécution est représentée à la figure 3. La circonférence extérieure est interrompue sur un angle x dans la zone inférieure de la découpe 16. Il en est donc de même du lamage 19 formé par les deux diamètres et de la portée cylindrique extérieure 15' des disques 12'. On conserve ainsi toute l'épaisseur du châssis auxiliaire 8 sur la hauteur h entre le bord intérieur de la découpe 16 et le bord inférieur du châssis auxiliaire 8.In order to increase the resistance of the chassis auxiliary 8 to the vertical pressure in the part located below the circular cutouts 16 without increase the height of the auxiliary chassis at this place, an elongation downwards can become troublesome during skating, the countersink formed in the cutouts 16 by its two different diameters can be angularly limited. Such an execution is shown in Figure 3. The outer circumference is interrupted at an angle x in the lower area of the cutout 16. The same goes for the counterbore 19 formed by the two diameters and the span cylindrical outer 15 'of the discs 12'. We keep thus the entire thickness of the auxiliary chassis 8 on the height h between the inner edge of the cutout 16 and the lower edge of the auxiliary chassis 8.
