  • Patent number: 7264254
    Abstract: A cycle for sailing on land comprising a recumbent tricycle with a first wheel and seat positioned aft of second and third wheels. A frame boom extending anteriorly of the front wheels engages a tricycle sprint to support a sailing system. The jib sail of the sailing system may be adjusted during use through swing of the jib boom. The mast and combination of forestay, rear stay, mast sidestays and sprint sidestays cooperatively support attachment and use of jib sail to recumbent tricycle allowing application of wind force to stably motivate the land cycle. Further improvements disclosed and claimed include an electrical system including an electrical generator in cooperation with the rear wheel to convert mechanical energy to electrical energy for storage and use with accessories as well as an electrical motor which may be controlled to allow application of mechanical force in addition to wind force for vehicle motivation.

  • Patent number: 7182355
    Abstract: A land cycle for sailing on land comprising a recumbent tricycle with a first wheel and seat positioned aft of second and third wheels. A boom extending anteriorly of the front wheels engages a tricycle sprint to support a sailing system, which includes a vertically positioned mast engaged with the recumbent tricycle frame between the front wheels. A jib sail is positioned within a butterfly jib boom attached to the forestay and may be adjusted during use by the rider. The mast and combination of forestay, rear stay, mast sidestays and sprint sidestays cooperatively support attachment and use of said jib sail to said recumbent tricycle, thereby allowing a rider to apply wind force to stably motivate said land cycle. Further improvements disclosed and claimed include an independent rear brake, butterfly jib boom sleeve, a tubular jib spar, and a tubular forestay.
