Abstract A practical vehicle for riding propelled by reciprocating occupant motion comprising a sliding seat on rails mounted on a vehicle frame in which frame three or four wheels are rotatively mounted. The mechanism comprises a chain attached by its two ends to the movable seat and which chain transmits the reciprocating motion through loose sprockets to two freewheels mounted on separate and parallel axles on bearings. On the same axles a pair of intermeshed spurgears are driven in each back and forth motion of the chain by one of the two freewheels, the one locked on its axle which is the driving element. The second spurgear is following freely the motion of the first, and vice versa. The combination of both the freewheels and the intermeshed spurgears alters the reciprocating motion to a continuous and single direction motion of the chainwheel which is attached to the extension of one of the two parallel axles. The chainwheel with a separate chain gives through the shaft supporting the rear wheels the forward propulsion to the vehicle.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
154 words
A vehicle comprising a frame supported by wheels rotatively mounted with a movable seat sliding on the curved rails of the said frame and adapted to be reciprocated by the rider's force and a motion transmission mechanism comprising: a. A pair of freewheels mounted on separate and parallel shafts on bearings and turning with a chain attached by its two ends to the sliding seat. b. A pair of intermeshed spurgears attached to the same shafts with the freewheels such that, in combination, a forward propulsion may be achieved by both forward and reverse occupant motion. c. A chainwheel attached to the extension of one of the two shafts supporting the freewheels and the spurgears which transmits the motion with another chain to the rear wheels supporting the vehicle. d. A plurality of loose and fixed sprockets used for directing the motion of the chains and for turning the different shafts of the mechanism.
