Driving movement by levers for the re-education of the joints and suitable for the propulsion of a tricycle

摘要

The drive system includes levers of first type (2,3) with attached fixed pivot points, or couplings through moving axis and levers (7). An axis (8) common to ends of levers (7) is free and independent. This is inserted by ends (45,46) into casing including component (H86) mounted with two sealed bearings. A double crankshaft transmits normal circular motion. The drive system includes levers of first type (2,3) with attached fixed pivot points, or couplings through moving axis and levers (7) associated with them. An axis (8) common to ends of levers (7) is free and independent. This is inserted by ends (45,46) into open, non-lubricated casing including component (H86) mounted with two sealed bearings on axis (52). A double crankshaft transmits normal circular motion, in continuous rotation, each of the levers contribute to the drive in turn, as they rise, fall, advance and return.
