Abstract

The scooter consists of a handlebar (1) in a column (2) which has an articulation at its base enabling these two components to oscillate longitudinally. When the user manually activates the handlebar in a longitudinal to and fro movement a transmission arm (4) articulated on the spindle (5) at the top of the column drives a chain by means of opposite ratchet gears.

Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

La présente invention concerne un vélo-patin à propulsion manuelle.  The present invention relates to a hand-propelled skate bike.

A l'heure actuelle une patinette traditionnelle ne peut avancer qu'avec la poussée du pied de l'utilisateur pour atteindre seulement une vitesse très limitée.  At present a traditional scooter can only advance with the push of the user's foot to reach only a very limited speed.

Le vélo-patin selon l'invention permet de remédier à ces inconvénients. Il comporte en effet selon une première caractéristique, un guidon classique pouvant remplir simultanément la fonction de levier propulseur grâce à sa colonne munie d'une articulation sur l'extrémité inférieure et d'un bras de transmission articulé sur l'extrémité supérieure.  The bicycle-skate according to the invention overcomes these drawbacks. According to a first characteristic, it in fact comprises a conventional handlebar which can simultaneously fulfill the function of propellant lever thanks to its column provided with an articulation on the lower end and with a transmission arm articulated on the upper end.

Le bras de transmission comporte à sa base un essieu transversal pouvant coulisser longitudinalement ainsi que deux pignons à encliquetage opposé de manière à entraîner toujours dans le sens de la marche une chaîne primaire classique. Un moyeu primaire transmet ce même mouvement au moyeu de la roue arrière par une chaîne secondaire classique. The transmission arm comprises at its base a transverse axle which can slide longitudinally as well as two pinions with opposite clicks so as to always drive in the direction of travel a conventional primary chain. A primary hub transmits this same movement to the rear wheel hub by a conventional secondary chain.

Ainsi quand l'utilisateur actionne manuellement le guidon en va-et-vient longitudinal, il n'a plus besoin de pousser le vélo-patin avec son pied ; ensuite il pourra sélectionner une vitesse adéquate comme sur une bicyclette classique. So when the user manually operates the handlebar back and forth, he no longer needs to push the bike-skate with his foot; then he will be able to select an adequate speed like on a classic bicycle.

Selon des modes particuliers de réalisation une selle et un appui-pied peuvent être prévus pour la conduite assise.  According to particular embodiments, a saddle and a footrest can be provided for seated driving.

Les dessins annexés illustrent l'invention : La figure 1 représente l'aspect du vélo-patin.  The accompanying drawings illustrate the invention: Figure 1 shows the appearance of the bike-skate.

Les figures 2,3, 4,5, 6,7, 8,9, 10, 11, 12 et 13 représentent les détails du vélo-patin. Figures 2,3, 4,5, 6,7, 8,9, 10, 11, 12 and 13 show the details of the bike-skate.

Les figures 14,15, 16 et 17 représentent une variante du vélo-patin. Figures 14,15, 16 and 17 show a variant of the bike-skate.

En référence à ces dessins, le vélo-patin comporte un guidon (1) classique et une colonne (2) munie à sa base d'un essieu transversal (3) permettant à ces deux organes une articulation longitudinale selon l'axe (15) de symétrie. Un bras (4) de transmission articulé sur l'axe (5) au sommet de la colonne (2) comporte un essieu (8) transversal fixé à sa base pouvant se déplacer dans deux coulisses (9) (10) longitudinales.  With reference to these drawings, the bicycle-skate comprises a conventional handlebar (1) and a column (2) provided at its base with a transverse axle (3) allowing these two members a longitudinal articulation along the axis (15) of symmetry. A transmission arm (4) articulated on the axis (5) at the top of the column (2) comprises a transverse axle (8) fixed at its base which can move in two longitudinal slides (9) (10).

Deux pignons (7) (6) à encliquetage opposé sont fixés respectivement au milieu de l'essieu (8) et de l'entretoise (11) du bras (4) pour entraîner toujours dans le sens de la marche une chaîne (12) primaire classique pendant le va-etvient du bras (4). La chaîne (12) primaire est disposée autour du pignon (13) avant et du pignon (14) arrière fixé sur le moyeu (16) primaire selon l'axe (15) de symétrie de manière à entraîner dans le même sens une chaîne (17) secondaire classique qui tourne parallèlement autour du même moyeu (16) pour transmettre ce mouvement au moyeu (18) de la roue arrière. Ainsi quand l'utilisateur actionne manuellement le guidon (1) en va-et-vient longitudinal, total ou partiel, la roue arrière est toujours entraînée dans le sens de la marche. Two pinions (7) (6) with opposite snap are fixed respectively in the middle of the axle (8) and of the spacer (11) of the arm (4) to always drive in the direction of travel a chain (12) classic primary during the back and forth of the arm (4). The primary chain (12) is arranged around the front sprocket (13) and the rear sprocket (14) fixed on the primary hub (16) along the axis (15) of symmetry so as to drive in the same direction a chain ( 17) conventional secondary which rotates in parallel around the same hub (16) to transmit this movement to the hub (18) of the rear wheel. Thus when the user manually actuates the handlebar (1) back and forth longitudinal, total or partial, the rear wheel is always driven in the direction of travel.

Le pignon (13) et les deux moyeux (16) (18) peuvent tourner autour des axes (35) (36) (37) respectifs mais sans pouvoir se déplacer transversalement. Deux roulements à billes (19) (20) dont les anneaux centraux sont fixés autour des extrémités de l'essieu (3) se logent respectivement dans le berceau (21) gauche et droit selon l'axe (22) transversal de manière à constituer l'articulation longitudinale de la colonne (2). Les extrémités de l'essieu (8) sont encapuchonnées par deux galets (23) (24) en matériau composite dont le diamètre extérieur est à peine inférieur à la hauteur des coulisses (9) (10). La largeur (25) identique des essieux (3) (8) ainsi assemblés est à peine inférieure à l'espacement (26) interne des longerons (27) (28) de manière à faciliter le montage et le coulissement respectif. Un roulement à billes (29) fixé sur l'extrémité supérieure de la colonne (2) comporte dans l'anneau (30) central des cannelures longitudinales identiques à celles réalisées sur l'axe (5) d'articulation jusqu'au filetage servant au vissage de l'écrou (31) autobloquant. The pinion (13) and the two hubs (16) (18) can rotate around the respective axes (35) (36) (37) but without being able to move transversely. Two ball bearings (19) (20) whose central rings are fixed around the ends of the axle (3) are housed respectively in the cradle (21) left and right along the transverse axis (22) so as to constitute the longitudinal articulation of the column (2). The ends of the axle (8) are capped by two rollers (23) (24) made of composite material, the outside diameter of which is barely less than the height of the slides (9) (10). The identical width (25) of the axles (3) (8) thus assembled is barely less than the internal spacing (26) of the side members (27) (28) so as to facilitate the respective mounting and sliding. A ball bearing (29) fixed on the upper end of the column (2) has in the central ring (30) longitudinal grooves identical to those produced on the axis (5) of articulation up to the thread serving when screwing the self-locking nut (31).

Deux orifices comportant les mêmes cannelures sont réalisés sur le bras (4) pour permettre le passage et l'assemblage de l'axe (5). Chaque extrémité de l'anneau (30) central dépasse suffisamment l'épaisseur du roulement à billes (29) de manière à lui éviter le frottement contre le bras (4). Two holes with the same grooves are made on the arm (4) to allow the passage and assembly of the axis (5). Each end of the central ring (30) sufficiently exceeds the thickness of the ball bearing (29) so as to avoid friction against the arm (4).

Deux longerons (27) (28) parallèles comportant respectivement à l'intérieur trois saillies (32) (33) (34) longitudinales sont assemblés par deux axes (35) (36) transversaux pour constituer le châssis du vélo-patin. Two parallel beams (27) (28) comprising respectively three protrusions (32) (33) (34) longitudinal are assembled by two axes (35) (36) transverse to form the chassis of the bike-skate.

Les extrémités des axes (35) (36) sont taraudées longitudinalement pour recevoir les boulons respectifs de fixation. Quatre orifices d'un diamètre identique à ce taraudage sont réalisés sur les longerons (27) (28) pour le passage desdits boulons. L'axe (37) du moyeu (18) arrière est fixé classiquement par deux écrous à oreille. Le tendeur (38) de la chaîne (12) primaire est constitué de deux ressorts (39) (40) hélicoïdaux dont les extrémités sont accrochées respectivement aux orifices des pattes (41) (42) et de l'axe (43) du pignon (44). Ce pignon (44) est en matériau composite et tourne librement autour de son axe (43). Un berceau (45) de butée (46) en caoutchouc est fixé dans chaque coulisse (9) (10) pour assurer la fin de course de l'essieu (8) vers l'avant. Un orifice (47) permet à l'utilisateur de pousser la butée (46) afin de la remplacer par une autre moins longue lorsqu'il veut augmenter la course de l'essieu (8). Deux câbles (48) (49) gainés classiques relient respectivement le frein (50) et le dérailleur (51) aux leviers (52) (53) fixés sur le guidon (1). Deux orifices (54) (55) identiques sont réalisés sur les longerons (27) (28) près de l'axe (22) pour permettre le passage de la tige (56) de la manette (57) gauche et de la manette droite. Un tablier (58), en métal ou en matériau composite à surface antidérapante, est fixé sur les longerons (27) (28) de manière à compléter la structure du vélo-patin. Ce tablier (58) comporte : -un garde-boue (59) muni d'une fente (60) pour le montage d'un frein (50) classique, -un orifice (61) pour la sortie du câble (48),

Figure img00030002

- deux orifices (62) (63) pour l'entrée des câbles (48) (49), - une fente (64) longitudinale pour le passage du bras (4) selon l'axe (15) de symétrie, - trois orifices (65) (66) (67) identiques et équidistants The ends of the axes (35) (36) are tapped longitudinally to receive the respective fixing bolts. Four holes of a diameter identical to this thread are made on the side members (27) (28) for the passage of said bolts. The axis (37) of the rear hub (18) is conventionally fixed by two wing nuts. The tensioner (38) of the primary chain (12) consists of two helical springs (39) (40), the ends of which are hooked respectively to the orifices of the legs (41) (42) and of the pin (43) of the pinion (44). This pinion (44) is made of composite material and rotates freely around its axis (43). A rubber stopper cradle (45) is fixed in each slide (9) (10) to ensure the end of travel of the axle (8) towards the front. A hole (47) allows the user to push the stop (46) in order to replace it with another shorter one when he wants to increase the stroke of the axle (8). Two conventional sheathed cables (48) (49) respectively connect the brake (50) and the derailleur (51) to the levers (52) (53) fixed on the handlebars (1). Two identical orifices (54) (55) are made on the longitudinal members (27) (28) near the axis (22) to allow the passage of the rod (56) of the left handle (57) and the right handle . An apron (58), made of metal or a composite material with a non-slip surface, is fixed to the side members (27) (28) so as to complete the structure of the bicycle-skate. This apron (58) comprises: -a mudguard (59) provided with a slot (60) for mounting a conventional brake (50), -an orifice (61) for the exit of the cable (48),

longitudinalement pour le boulonnage du berceau (68) de la butée (69) en caoutchouc, - deux orifices (70) (71) identiques aux orifices (54) (55), -un espacement (72) à l'extrémité avant suffisamment large pour le passage de la colonne (2) lors de son montage ou démontage.  longitudinally for the bolting of the cradle (68) of the rubber stop (69), - two orifices (70) (71) identical to the orifices (54) (55), - a spacing (72) at the sufficiently wide front end for the passage of the column (2) during its assembly or disassembly.

Les deux empreintes (73) (74) pointillées sur le tablier (58) indiquent la position théorique des pieds de l'utilisateur lorsqu'il actionne le guidon (1) en va-et-vient longitudinal. The two indentations (73) (74) dotted on the apron (58) indicate the theoretical position of the feet of the user when he actuates the handlebar (1) back and forth longitudinally.

Le berceau (68) comporte : -un dossier (75) incliné pour bloquer longitudinalement la butée (69), - deux saillies (76) (77) internes pour coincer la butée (69), -un espacement (78) à peine inférieur au diamètre du pneu de la roue avant de manière à pouvoir le coincer lorsque le guidon (1) est démonté et couché sur le tablier (58), - une embase (79) munie de deux orifices identiques aux orifices (65) (66) (67) prévus pour le boulonnage. Ainsi quand l'utilisateur tire le guidon (1) la butée (69) assure la fin de course de la colonne (2). L'orifice (65) sera utilisé pour reculer la fixation du berceau (68) lorsque l'utilisateur veut augmenter la course de la colonne (2). Le berceau (21) gauche du roulement à billes (19) comporte un orifice (80) identique aux orifices (54) (70) supérieurs de manière à recevoir la tige (56) de la manette (57). L'extrémité supérieure de la tige (56) est emboîtée dans la manette (57) et fixée par un boulon (81) tandis que son extrémité inférieure pliée en angle droit bloque le roulement à billes (19) grâce à la tension exercée par un ressort (82) hélicoïdal et à la fente longitudinale de la saillie (33) dont la largeur est égale au diamètre de la tige (56). Après avoir appuyé à fond la manette (57) verticalement l'utilisateur peut la tourner d'un quart de tour pour débloquer le roulement à billes (19). Le berceau du roulement à billes droit et la saillie intermédiaire droite étant équipés de la même façon, ils permettent à l'utilisateur de démonter le guidon (1) et de The cradle (68) comprises: - an inclined backrest (75) for longitudinally locking the stop (69), - two internal projections (76) (77) for wedging the stop (69), - a space (78) barely less to the diameter of the tire of the front wheel so as to be able to wedge it when the handlebar (1) is removed and lying on the bulkhead (58), - a base (79) provided with two orifices identical to the orifices (65) (66) (67) provided for bolting. So when the user pulls the handlebars (1) the stop (69) ensures the end of travel of the column (2). The hole (65) will be used to move back the fixing of the cradle (68) when the user wants to increase the stroke of the column (2). The cradle (21) left of the ball bearing (19) has an orifice (80) identical to the orifices (54) (70) above so as to receive the rod (56) of the lever (57). The upper end of the rod (56) is fitted into the handle (57) and fixed by a bolt (81) while its lower end bent at right angles blocks the ball bearing (19) thanks to the tension exerted by a helical spring (82) and to the longitudinal slot of the projection (33) whose width is equal to the diameter of the rod (56). After having fully pressed the lever (57) vertically the user can turn it a quarter of a turn to unlock the ball bearing (19). The cradle of the right ball bearing and the right intermediate projection being equipped in the same way, they allow the user to disassemble the handlebar (1) and

le coucher longitudinalement sur le tablier (58) selon l'axe (15) de symétrie, grâce à l'appui-guidon (83) et au berceau (68), de manière à pouvoir transporter plus facilement le vélo-patin. Une sangle (84) ou un tendeur entourant l'ensemble bloquera le guidon (1) couché.  lay it longitudinally on the apron (58) along the axis (15) of symmetry, thanks to the handlebar support (83) and the cradle (68), so as to be able to transport the bike-skate more easily. A strap (84) or a tensioner surrounding the assembly will block the handlebars (1) lying down.

Dans la forme de réalisation selon les figures 14,15, 16 et 17, le vélo-patin comporte un appui-pied (85) et une selle (86), dont le support (87) fixé sur le tablier (58) couvre partiellement une roue arrière adéquate, permettant à l'utilisateur assis d'effectuer aisément tous les mouvements manuels de propulsion et de conduite.  In the embodiment according to FIGS. 14, 15, 16 and 17, the bicycle-skate comprises a footrest (85) and a saddle (86), the support (87) of which is fixed on the apron (58) partially covers a suitable rear wheel, allowing the seated user to easily carry out all manual propulsion and driving movements.

Le tablier (58) comporte donc à la place du garde-boue (59) une fente longitudinale pour le passage d'une roue arrière plus grande ainsi que six orifices (88) (89) (90) (91) (92) (93) d'un diamètre identique aux orifices (65) (66) (67) centraux. Six orifices identiques sont réalisés sur les longerons (27) (28) pour compléter la fixation de l'appui-pied (85) selon son embase (94). La partie centrale de l'appui-pied (85) est identique au berceau (68) de manière à remplacer entièrement la fonction de ce dernier. Une échancrure (95) située au sommet de la selle (86) remplace l'appui-guidon (83). Un garde-boue (96) et un frein (97) classique fixés sur le support (87) complètent l'équipement du vélo-patin pour la conduite assise.  The apron (58) therefore has instead of the mudguard (59) a longitudinal slot for the passage of a larger rear wheel as well as six holes (88) (89) (90) (91) (92) ( 93) of identical diameter to the central orifices (65) (66) (67). Six identical holes are made on the side members (27) (28) to complete the fixing of the footrest (85) according to its base (94). The central part of the footrest (85) is identical to the cradle (68) so as to completely replace the function of the latter. A notch (95) located at the top of the saddle (86) replaces the handlebar support (83). A conventional mudguard (96) and brake (97) fixed on the support (87) complete the equipment of the skate bike for seated driving.

Les figures 7,9 et 12 représentent respectivement en coupe, le berceaux (45) (68) et l'ensemble de la manette (57).  Figures 7,9 and 12 show respectively in section, the cradles (45) (68) and the entire handle (57).

A titre indicatif, les deux longerons (27) (28) et le tablier (58) peuvent être constitués par une seule pièce en métal ou en matériau composite ; le diamètre extérieur de la roue avant et la longueur de la fourche peuvent être augmentés suivant l'utilisation visée.  As an indication, the two beams (27) (28) and the deck (58) can be constituted by a single piece of metal or composite material; the outside diameter of the front wheel and the length of the fork can be increased depending on the intended use.

Le vélo-patin selon l'invention est particulièrement destiné aux utilisateurs valides ou partiellement infirmes des membres inférieurs. The bicycle-skate according to the invention is particularly intended for able-bodied or partially disabled users of the lower limbs.
