The invention can be used for producing ground, water and air transport vehicles fitted with a muscle, wind and machine drive. Said transport vehicle can be provided with two, three and four wheels. In order to prevent a tilting by a centrifugal force a frame is hinged to the axis of coaxial wheels, making it possible to perform an elastic curve around a longitudinal axis. A pivot pin of foot drive levers is mounted behind the rim of a drive wheel in a direction away from the seat and farther than axis of handle levers at a distance corresponding to anthropometric proportions of the hands and legs. The foot and handle drive can be of an autonomous or synchronous variety and united with a by-pass roller by a common flexible drive. A tail end of the body is embodied in the form of a barrel and doors are displaced behind passengers or are let down. The seat of the transport facility is suspended by means of a rotatable joint and fitted with an energy-absorption shock absorber, protecting the passenger from a lateral or tail shock. A light-sized bicycle-scooter is fitted with a collapsible frame and a sectional lantern gear. Transport facility roller skates is fitted with an opening boot with a platform for attachment to the leg and drive levers thereof is pivotally connected to a horizontal guide, mounted on the platform, and to a planetary gear mounted on the axis of the front and /or rear rollers. Said transport facility is fitted with two anvil coaxial rollers only and has a center of gravity below the roller axle. The invention can be embodied in the form of a heavy tractor fitted with a motor arranged below the wheel axle or a light pyramidal sailing ship fitted with a seat placed lower than the wheel axle and controlled by the rake of sail. A light-sized comfortable ecologically clean transport facility fitted with an efficient muscle drive ensuring a speed of car can substitute a car in the city. |
