Abstract

La présente invention concerne un appareil d'entraînement double pour bicyclette, d'une configuration simple comportant un fil qui est connecté à un guidon, guidon qu'il est possible de tirer ou de faire tourner pour entraîner un arbre d'entraînement, quelle que soit la pression appliquée à une pédale dans une bicyclette entraînée par pédales que l'on actionne en montant sur la pédale. L'appareil d'entraînement double (A) pour bicyclette est configuré de façon qu'un arbre d'entraînement (8) soit couplé à un pignon inférieur (7), qu'un pignon (13) qui est connecté par une chaîne (12) à un pignon (11) monté sur un arbre de roue arrière (10) soit installé sur l'arbre d'entraînement ainsi que deux manivelles de pédalier (14) couplées aux pédales (15), et que l'énergie soit transmise à un tube d'arbre d'entraînement (23) quand un fil (28) est tiré d'un guidon (4) ou d'un cadre de vélo (2). L'arbre d'entraînement (8) est fixé à l'intérieur du tube d'arbre d'entraînement (23) qui est ajusté dans le pignon inférieur (7) par l'intermédiaire d'un palier (22) de façon que l'arbre d'entraînement (8) soit supporté par un palier (9) et par un palier unidirectionnel (24). Une bague d'entraînement (25) est couplée par un palier unidirectionnel (26) à une extrémité du tube d'arbre d'entraînement (23) exposé vers l'extérieur en partant du pignon inférieur (7), de façon qu'une extrémité du fil (28) connecté au guidon (4) ou au cadre (2) soit fixée à la bague d'entraînement (25). Le pignon (13) est monté à l'autre extrémité du tube d'arbre d'entraînement (23). La bague d'entraînement (25) présente une surface latérale sur laquelle est formée une rainure de ressort (25a) prévue pour recevoir un ressort de torsion (27), de façon que les deux extrémités du ressort de torsion (27) soient fixées à une butée (2a) solidaire de la bague d'entraînement (25) et du cadre (2). Des poignées (20, 20', 20") qui sont couplées au guidon (4) ou au cadre (2) peuvent être mises en œuvre pour fournir de l'énergie à l'appareil d'entraînement double (A) et réduire l'effort des jambes du cycliste quand celui-ci commence à ressentir la fatigue après une longue période de circulation à vélo (1). La présente invention permet aux cyclistes de soumettre les bras à un exercice physique pendant la circulation à vélo, et permet de se déplacer rapidement à vélo quand le cycliste utilise simultanément les bras et les jambes. La présente invention permet également aux personnes présentant des handicaps des membres inférieurs de circuler à vélo en utilisant les poignées (20, 20', 20") couplées au guidon (4) ou au cadre (2) sous la réserve que de telles personnes présentant des handicaps des membres inférieurs puissent se maintenir en équilibre à l'arrêt.
