  • Piston assembly for use with a bicycle operated air pump
    Patent number: 5626072
    Abstract: An air pump for use with a chain-driven bicycle having a free wheel. 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 driven by a sprocket. Rotation of the sprocket reciprocates the double-ended piston rod in the cylinders. The cylinders are each integrally formed with a manifold that uses an elastomeric band covering a passage from the cylinder interior to inside the manifold as a one-way valve. An enlarged diameter skirt on each cylinder allows air to enter the cylinder on each intake stroke. A cap defining the piston head is locked onto each piston and holds a seal in place on the piston. An integral clamp assembly allows the pump to be removably mounted on a bicycle chain stay. The lower run of the bicycle drive chain engages the drive sprocket of the pump assembly, and a chain retainer is used to maintain the engagement of the drive chain with the drive sprocket.
