Latest Patents

Hopper's latest patents include a piston assembly for use with a bicycle-operated air pump. This innovative air pump is designed for chain-driven bicycles equipped with a free wheel. The pump assembly features a pair of opposed cylinders and a double-ended piston rod mounted in a housing. The piston rod is designed with a bearing slot that engages a crank pin on a crankshaft driven by a sprocket. As the sprocket rotates, it reciprocates the double-ended piston rod within the cylinders. Each cylinder is integrally formed with a manifold that utilizes an elastomeric band as a one-way valve. An enlarged diameter skirt on each cylinder allows air to enter during the intake stroke. The design also includes a cap that locks onto each piston, holding a seal in place. An integral clamp assembly enables the pump to be easily mounted on a bicycle chain stay. The innovative mechanism allows for efficient air pumping to inflate bicycle tires.
