Description

La présente invention a pour objet un patin à roulettes réalisé entièrement en matière plastique, du type comprenant une plate-forme en deux parties avant et arrière reliées télescopiquement l'une à l'autre, chaque plate-forme avant et arrière portant l'axe de rotation des roues avant et arrière, un système de réglage et de blocage des deux plate-­formes l'une par rapport à l'autre dans la position désirée, une coquille avant fixée sur la plate-forme avant et une coquille arrière fixée sur la plate-forme arrière aptes à retenir la chaussure sur le patin à roulettes au moyen d'au moins une lanière de serrage.The present invention relates to a roller skate made entirely of plastic, of the type comprising a platform in two front and rear parts telescopically connected to each other, each front and rear platform carrying the axis of rotation of the front and rear wheels, a system for adjusting and locking the two platforms with respect to each other in the desired position, a front shell fixed on the front platform and a rear shell fixed on the rear platform capable of retaining the shoe on the roller skate by means of at least one tightening strap.

Le but de la présente invention est de réaliser un patin de ce type qui soit peu coûteux à fabriquer mais qui présente néanmoins toutes les possibilités de suspension et de souplesse de braquage et les qualités de résistance des patins actuels et qui soit, en outre, facile à régler en longueur.The object of the present invention is to produce a skate of this type which is inexpensive to manufacture but which nevertheless has all the possibilities of suspension and steering flexibility and the qualities of resistance of current skates and which is also easy to adjust in length.

Ce but est atteint en ce que dans le patin à roulettes selon l'invention, le système de réglage et de blocage des deux plate-formes l'une par rapport à l'autre est formé, d'une part, par une crémaillère formée sur une partie d'une première plate-forme apte à s'étendre sous la seconde plate-forme et, d'autre part, par une languette dentée solidaire de la seconde plate-forme et apte à être engagée dans la crémaillère de la première plate-forme.This object is achieved in that in the roller skate according to the invention, the adjustment and blocking system of the two platforms relative to one another is formed, on the one hand, by a rack formed on a part of a first platform able to extend under the second platform and, on the other hand, by a toothed tongue integral with the second platform and able to be engaged in the rack of the first platform.

Avantageusement, la languette est montée pivotante sur la seconde plate-forme et est apte à être engagée dans la crémaillère et à y être maintenue au moyen d'un levier formant came.Advantageously, the tongue is pivotally mounted on the second platform and is able to be engaged in the rack and to be held there by means of a lever forming a cam.

Selon une forme de réalisation préférée, le serrage du patin à roulettes est effectué au moyen d'une seule lanière et une plaque de répartition de l'effort de serrage sur le cou de pied est prévue sur la coquille avant.According to a preferred embodiment, the tightening of the roller skate is carried out by means of a single strap and a plate for distributing the tightening force on the instep is provided on the front shell.

Avantageusement aussi, chaque patin à roulettes présente des moyens de suspension et d'amortissement.Advantageously also, each roller skate has suspension and damping means.

De toute façon, l'invention sera bien comprise et d'autres ca­ractéristiques seront mises en évidence à l'aide de la description qui suit en référence au dessin schématique annexé illustrant à titre d'exem­ple non limitatif deux formes de réalisation préférées de ce patin à roulettes:

  • - Figure 1 en est une vue en perspective ;
  • - Figure 2 est une vue en coupe longitudinale du patin à roulet­tes de la figure 1, en position débloquée ;
  • - Figure 3 est une vue en coupe selon III-III de figure 2 ;
  • - Figure 4 est une vue en coupe longitudinale du patin à roulet­tes selon une seconde forme de réalisation, en position bloquée.
Anyway, the invention will be well understood and other characteristics will be highlighted with the aid of the description which follows with reference to the appended schematic drawing illustrating by way of nonlimiting example two preferred embodiments of this skate on casters:
  • - Figure 1 is a perspective view;
  • - Figure 2 is a longitudinal sectional view of the roller skate of Figure 1, in the unlocked position;
  • - Figure 3 is a sectional view along III-III of Figure 2;
  • - Figure 4 is a longitudinal sectional view of the roller skate according to a second embodiment, in the locked position.

Ainsi que le montre notamment la figure 1, le patin à roulettes selon l'invention comprend deux plate-formes avant (1) et arrière (2) portant chacune l'axe (3) de rotation des roues (5) du patin à roulettes.As shown in particular in FIG. 1, the roller skate according to the invention comprises two front (1) and rear (2) platforms each carrying the axis (3) of rotation of the wheels (5) of the roller skate .

Chaque plate-forme (1,2) est munie d'une coquille respectivement (7,8) formant cale-pied avant et arrière et portant la lanière de fixation (9).Each platform (1,2) is provided with a shell respectively (7,8) forming front and rear toe clips and carrying the fixing strap (9).

La forme des plate-formes avant (1) et arrière (2) est montrée plus particulièrement sur les figures 2 et 3.The shape of the front (1) and rear (2) platforms is shown more particularly in FIGS. 2 and 3.

La plate-forme avant (1) est constituée par une poutre longitu­dinale (11) portant à son extrémité avant deux bras coudés (12,13). Le bras coudé (12) situé à l'extérieur forme à son extrémité libre le moyeu (12a) portant l'axe (3) des roues avant (5).The front platform (1) consists of a longitudinal beam (11) carrying at its front end two bent arms (12,13). The bent arm (12) located outside forms at its free end the hub (12a) carrying the axis (3) of the front wheels (5).

Le matériau plastique, dont est formé ce bras (12), autorise une certaine flexion de celui-ci créant un effet de suspension. Cet effet de flexion du bras (12) est limité par le bras (13) situé à l'intérieur de celui-ci. Ce bras (13) a, en effet, sensiblement la même forme que le bras (12) mais est plus rigide que ce dernier car il est double et donc moins flexible. Ce bras (13) présente une cavité (13a) demi-cylindrique apte à accueillir la partie (12a) du bras (12) formant moyeu lors d'une flexion de celui-ci.The plastic material from which this arm (12) is formed allows a certain bending of the latter creating a suspension effect. This flexing effect of the arm (12) is limited by the arm (13) located inside of it. This arm (13) has, in fact, substantially the same shape as the arm (12) but is more rigid than the latter because it is double and therefore less flexible. This arm (13) has a semi-cylindrical cavity (13a) capable of receiving the part (12a) of the arm (12) forming a hub during bending of the latter.

La flexion des deux bras (12,13) est finalement limitée par une butée (14) également solidaire de la plate-forme avant (1).The bending of the two arms (12,13) is finally limited by a stop (14) also integral with the front platform (1).

Le bras coudé (12) présente également à son extrémité, sur sa partie (12a) formant moyeu, un ergot (12b) saillant radialement en direction horizontale.The bent arm (12) also has at its end, on its part (12a) forming a hub, a lug (12b) projecting radially in the horizontal direction.

Cet ergot (12b) coopère avec un évidement associé (13b) ménagé à l'extrémité libre du bras (13) pour autoriser un certain basculement transversal de la partie formant moyeu (12a), correspondant à la création d'un angle de braquage.This lug (12b) cooperates with an associated recess (13b) formed at the free end of the arm (13) to allow a certain transverse tilting of the hub part (12a), corresponding to the creation of a steering angle.

Un patin de freinage (4) de type connu peut être fixé sur le bras de suspension (12) comme montré à la figure 1.A braking pad (4) of known type can be fixed on the suspension arm (12) as shown in FIG. 1.

A sa partie arrière, la poutre (11) de la plate-forme avant a, en section transversale, sensiblement la forme d'un C (Cf. Figure 3) délimitant deux rainures latérales formant glissières (15).At its rear part, the beam (11) of the front platform has, in cross section, substantially the shape of a C (see FIG. 3) delimiting two lateral grooves forming slides (15).

Cette poutre (11) présente également une découpe (16) longitu­dinale centrale s'étendant à peu près de son milieu jusqu'à son extrémité arrière. Une languette (17) élastique est montée pivotante en (18) sur cette poutre, et est apte à se déplacer dans sa découpe (16).This beam (11) also has a central longitudinal cutout (16) extending approximately from its middle to its rear end. An elastic tongue (17) is pivotally mounted at (18) on this beam, and is able to move in its cutout (16).

Cette languette (17) est munie à son extrémité libre de dents (17a) dont le rôle sera expliqué plus loin.This tongue (17) is provided at its free end with teeth (17a) whose role will be explained below.

Un levier (19) est également monté pivotant en (20) à l'extrémité arrière de la découpe (16). Ce levier (19) présente une partie formant came (19a) apte à appuyer sur l'extrémité de la languette (17) et une partie (19b) en permettant l'actionnement.A lever (19) is also pivotally mounted at (20) at the rear end of the cutout (16). This lever (19) has a part forming a cam (19a) capable of pressing on the end of the tongue (17) and a part (19b) allowing actuation.

La plate-forme arrière (2) est également formée par une poutre longitudinale (21).The rear platform (2) is also formed by a longitudinal beam (21).

De même que la poutre avant (11), cette poutre (21) comporte à son extrémité arrière deux bras coudés (22,23), le bras coudé (22) situé à l'extérieur formant moyeu en (22a) et portant l'axe (3) des roues arrières (5), et les deux bras (22,23) formant une suspension dont la flexion est limitée, d'une part, par la cavité (23a) du bras (23) et, d'autre part, par la butée (24). De même que pour la plate-forme avant (1), un ergot (22b) du bras (22) autorise avec un évidement associé (23b) du bras (23) un certain basculement transversal du moyeu (22a).Like the front beam (11), this beam (21) has at its rear end two bent arms (22,23), the bent arm (22) located outside forming a hub at (22a) and carrying the axis (3) of the rear wheels (5), and the two arms (22,23) forming a suspension whose flexion is limited, on the one hand, by the cavity (23a) of the arm (23) and, on the other hand part, by the stop (24). As with the front platform (1), a lug (22b) of the arm (22) allows, with an associated recess (23b) of the arm (23), a certain transverse tilting of the hub (22a).

A sa partie avant, la poutre (21) de cette plate-forme arrière (2) a, en section transversale, la forme d'un Ω renversé apte à s'engager par chacune de ses ailes (25) dans les glissières (15) de la plate-forme avant (1). Le fond (26) de cette poutre en forme de Ω forme une crémail­lère dont la denture correspond à celle de la languette (17).At its front part, the beam (21) of this rear platform (2) has, in cross section, the shape of an inverted Ω capable of engaging by each of its wings (25) in the slides (15 ) of the front platform (1). The bottom (26) of this Ω-shaped beam forms a rack whose teeth correspond to that of the tongue (17).

L'ensemble crémaillère (26), languette (17) et levier (19) permet le réglage en longueur du patin à roulettes.The rack and pinion assembly (26), tongue (17) and lever (19) allows the length of the roller skate to be adjusted.

En effet, le levier (19) étant dans la position déverrouillée montrée à la figure 2, la languette (17) se redresse par élasticité et se désengage des dents de la crémaillère (26), et il suffit de faire coulis­ver la plate-forme arrière (2) dans la plate-forme avant (1). Lorsque la longueur voulue est atteinte, il suffit de faire pivoter le levier (19) vers le bas comme montré à la figure 4, celui-ci appuie alors sur la languette (17) et la pousse vers le bas de façon que ses dents (17a) entrent en prise avec celles de la crémaillère. Une fois ce mouvement terminé le levier (19) appuie par sa face plane sur la languette (17) et la maintient en engagement avec la crémaillère, de sorte qu'un ver­rouillage sûr est atteint.In fact, the lever (19) being in the unlocked position shown in FIG. 2, the tongue (17) straightens out by elasticity and disengages from the teeth of the rack (26), and it suffices to slide the platform rear (2) in the front platform (1). When the desired length is reached, simply rotate the lever (19) down as shown in Figure 4, it then presses on the tongue (17) and pushes it down so that its teeth ( 17a) engage with those of the rack. Once this movement completed the lever (19) presses by its flat face on the tongue (17) and maintains it in engagement with the rack, so that a secure locking is achieved.

Il est à noter que le levier (19) peut être ensuite facilement pivoté vers le haut par l'actionnement de sa partie (19b), en engageant simplement un doigt dans la découpe (16) et en poussant cette partie (19b) vers le haut.It should be noted that the lever (19) can then be easily pivoted upwards by actuating its part (19b), by simply engaging a finger in the cutout (16) and pushing this part (19b) towards the high.

La coquille avant (7) du patin à roulettes est formée de deux parties (27,28). La partie (27) de cette coquille présente une base (29) dont la section transversale est complémentaire de celle de la plate-­forme (1) à sa partie avant et qui est apte à être mise en place sur celle-ci par coulissement et à y être fixée par collage ou similaire.The front shell (7) of the roller skate is made up of two parts (27,28). The part (27) of this shell has a base (29), the cross section of which is complementary to that of the platform (1) at its front part and which is capable of being placed thereon by sliding and to be fixed by gluing or the like.

La partie supérieure de cette coquille (7) épouse sensiblement la forme de l'extrémité d'une chaussure.The upper part of this shell (7) substantially matches the shape of the end of a shoe.

Cette partie (27) comporte, en outre, une fente longitudinale (30) barrée à son extrémité supérieure par une arête transversale (30a) de la coquille (27).This part (27) further comprises a longitudinal slot (30) barred at its upper end by a transverse edge (30a) of the shell (27).

L'autre partie (28) de la coquille avant est formée d'une plaque apte à épouser sensiblement la forme d'un cou-de-pied.The other part (28) of the front shell is formed of a plate capable of substantially matching the shape of an instep.

Cette plaque (28) est munie d'une languette (31) apte à coulisser au moyen d'un ergot (32) dans la fente (30) de la partie (27) de la coquille avant (7). Cette languette (31) présente également à son extrémité libre un rebord (33) apte à venir en butée contre l'arête transversale (30a) de la coquille (27) de façon à arrêter le déplacement de la plaque (28).This plate (28) is provided with a tongue (31) capable of sliding by means of a lug (32) in the slot (30) of the part (27) of the front shell (7). This tongue (31) also has at its free end a flange (33) capable of abutting against the transverse edge (30a) of the shell (27) so as to stop the movement of the plate (28).

Cette plaque (28) présente, en outre, un évidement (34) pour le passage de la lanière de fixation (9).This plate (28) also has a recess (34) for the passage of the fixing strap (9).

La coquille arrière (8) du patin à roulettes forme cale-pied arrière.The rear shell (8) of the roller skate forms a rear toe clip.

De même que la coquille avant (7), cette coquille arrière pré­sente une base (35) de section transversale complémentaire de celle de la plate-forme (2) à sa partie arrière et qui est apte à être mise en place sur celle-ci par coulissement et à y être fixée par collage.Like the front shell (7), this rear shell has a base (35) of cross section complementary to that of the platform (2) at its rear part and which is suitable for being placed thereon. by sliding and to be fixed by gluing.

Cette coquille arrière (8) présente, en outre, deux ailes latérales (36) aptes à venir de part et d'autre du pied et une aile postérieure (37) apte à s'appuyer contre l'arrière de la chaussure.This rear shell (8) has, in addition, two lateral wings (36) able to come on either side of the foot and a rear wing (37) capable of pressing against the rear of the shoe.

Des fentes (38) sont ménagées dans ces ailes (36,37), comme montré notamment à la figure 2, afin de permettre le passage de la lanière de fixation (9).Slots (38) are provided in these wings (36, 37), as shown in particular in FIG. 2, in order to allow the passage of the fixing strap (9).

Ainsi que le montrent notamment les figures 1 et 2, le patin à roulettes selon l'invention peut être fixé à l'aide d'une seule lanière (9), notamment grâce à la plaque (28) de la coquille avant formant plaque de répartition et pouvant être réglée par rapport à la partie (27) de cette coquille avant, par son coulissement dans la fente (30) de celle-ci.As shown in particular in FIGS. 1 and 2, the roller skate according to the invention can be fixed using a single strap (9), in particular thanks to the plate (28) of the front shell forming a plate distribution and being adjustable relative to the part (27) of this front shell, by its sliding in the slot (30) thereof.

On peut noter également que grâce à la forme des ailes (36,37) de la coquille arrière et de la plaque (28) de la coquille avant, l'effet de serrage exercé par la lanière (9) sur le pied (et notamment sur le cou de celui-ci) est réparti uniformément sans risque de blesser celui-ci.It can also be noted that thanks to the shape of the wings (36, 37) of the rear shell and of the plate (28) of the front shell, the tightening effect exerted by the strap (9) on the foot (and in particular on the neck of the latter) is distributed evenly without risk of injuring it.

La figure 4 montre un autre exemple de réalisation du patin selon l'invention pouvant être serré à l'aide de deux lanières et non pas d'une seule comme dans l'exemple précédent.Figure 4 shows another embodiment of the shoe according to the invention can be tightened with two strips and not just one as in the previous example.

Dans cette autre forme de réalisation du patin à roulettes, les plate-formes avant et arrière sont identiques à celles de l'exemple précédent, et seront donc désignées par les mêmes références (1,2), de même que leurs différentes parties (suspension, blocage...etc).In this other embodiment of the roller skate, the front and rear platforms are identical to those of the previous example, and will therefore be designated by the same references (1,2), as well as their different parts (suspension , blocking ... etc).

Ce patin ne diffère donc de l'exemple précédent que par la forme de ses coquilles avant (40) et arrière (41).This pad therefore differs from the previous example only in the shape of its front (40) and rear (41) shells.

Ces deux coquilles (40,41) sont également mises en place par coulissement et fixées par collage sur les plate-formes respectives (1,2).These two shells (40,41) are also put in place by sliding and fixed by gluing on the respective platforms (1,2).

La coquille (40) présente deux ailes (42) s'étendant de part et d'autre de la plate-forme avant (1) et une partie (43) formant butée pour la chaussure. Chaque aile (42) est munie sur sa face externe d'une partie en saillie (44) apte à recevoir la courroie de serrage avant (non représentée sur le dessin) du patin.The shell (40) has two wings (42) extending on either side of the front platform (1) and a part (43) forming a stop for the shoe. Each wing (42) is provided on its external face with a projecting part (44) capable of receiving the front tightening strap (not shown in the drawing) of the pad.

La coquille arrière (41) présente également deux ailes (45) s'étendant de part et d'autre de la plate-forme arrière (2) et une partie (46) formant butée arrière pour la chaussure. De même que pour la coquille avant (40), chaque aile (45) est munie d'une partie en saillie (47) permettant le passage de la courroie de serrage arrière (non repré­sentée sur le dessin).The rear shell (41) also has two wings (45) extending on either side of the rear platform (2) and a part (46) forming a rear stop for the shoe. As for the front shell (40), each wing (45) is provided with a projecting part (47) allowing the passage of the rear tightening strap (not shown in the drawing).

Comme il va de soi la présente invention ne se limite pas aux seules formes de réalisation montrées ici à titre d'exemple non limitatif mais en embrasse, au contraire, toutes les formes de réalisation similaires ou équivalentes ; c'est ainsi que, par exemple, le système de blocage et de réglage de la longueur du patin pourrait être inversé par rapport aux plate-formes sans que l'on sorte pour autant du cadre de l'invention.As it goes without saying, the present invention is not limited to the sole embodiments shown here by way of non-limiting example, but embraces, on the contrary, all similar or equivalent embodiments; this is how, for example, the blocking and adjusting system of the length of the shoe could be reversed with respect to the platforms without departing from the scope of the invention.
