Title (EN) BICYCLE OPERATED AIR PUMP
(FR) POMPE A AIR POUR BICYCLETTE ACTIONNEE PAR LADITE BICYCLETTE
Abstract:
(EN) An air pump (10) for use with a chain-driven bicycle having a freewheel (28). The pump assembly comprises a pair of opposed cylinders and a double-ended piston rod mounted in a housing. The piston rod has a bearing slot which engages a crank pin on a crankshaft which is driven by a sprocket. Rotation of the sprocket reciprocates the double-ended piston rod in the cylinders. A hook-shaped extension of the housing fits over the top of the chain stay of the bicycle, and a vertically movable clamping member (46) provided with a ratchet mechanism abuts the underside of the chain stay; a lever operated cam clamps the chain stay intermediate the hook portion and the clamping member. The lower run of the bicycle drive chain engages the drive sprocket of the pump assembly. Reverse rotation of the bicycle's crank assembly causes the conventional freewheel to also rotate in a reverse direction without rotating the wheel of the bicycle. The resulting movement of the chain over the drive sprocket of the pump rotates the drive sprocket, which reciprocates the double-ended piston rod in the cylinders and pumps air to an article to be inflated.
(FR) Pompe à air (10) destinée à être utilisée avec une bicyclette à entraînement par chaîne et ayant un axe libre (28). L'ensemble pompe comprend une paire de cylindres opposés et une tige de piston à deux extrémités montée dans un carter. La tige de piston possède une fente de support dans laquelle vient s'engager un bouton de manivelle qui est entraîné par un pignon. Le mouvement de rotation du pignon induit le mouvement de va-et-vient de la tige de piston à deux extrémités, dans les cylindres. Une extension du logement de l'ensemble pompe, en forme de corchet, vient se fixer sur le dessus de la fourche du pédalier de la bicyclette, et un élément de serrage (46) se déplaçant verticalement et pourvu d'un mécanisme à cliquet, vient buter contre le dessous de la fourche du pédalier; une came commandée par un levier permet de bloquer la fourche du pédalier entre la partie en forme de crochet et l'élément de serrage. La partie inférieure de la chaîne de la bicyclette est en prise avec le pignon d'entraînement de l'ensemble pompe. La rotation en sens inverse du pédalier de la bicyclette entraîne la rotation en sens inverse de l'axe libre, sans provoquer la rotation de la roue de la bicyclette. Le mouvement de la chaîne sur le pignon d'entraînement de la pompe, fait tourner le pignon d'entraînement, ce qui provoque le mouvement de va-et-vient de la tige de piston à deux extrémités dans les cylindres et produit l'air nécessaire pour gonfler un objet.
