Abstract
A two-wheeled vehicle similar to a bicycle has a frame comprising four pivotably interconnected frame members of which the lower one is provided with a bearing for a sprocket wheel of a chain drive. A crank arm is connected to the sprocket wheel and cooperates with a connecting rod pivotably connected to the upper frame member carrying a saddle. Pedals are mounted on the lower frame member or the front frame member, the latter guiding the steering handle and the front wheel fork. The driving torque is achieved by alternatively shifting the weight between the saddle and the pedals. The saddle moves up and down reciprocally to the pedals and the steering handle forth and back giving the illusion of riding on horseback. The same structural principle is suitable also for a home-trainer.
Claims17
A two-wheeled vehicle similar to a bicycle comprising a frame having an upper frame member and a lower frame member pivotably connected to a front frame member by joints therebetween, and a rear frame member pivotably connected to the lower and upper frame members by joints therebetween, and wherein the upper frame member carries a saddle, the front frame member is provided with a bearing for a steering handle and a front wheel fork, the lower frame member is supported as a rocker on the axle of a rear wheel such that the rear part of the lower frame member extend beyond the axle, and is provided with a bearing for a driving sprocket wheel of a chain drive transmitting torque to the rear wheel, and the rear frame member is a link between the upper and lower frame members, the vehicle further comprising pedals connected to one of the front and the lower frame members, a crank arm fixed to the driving sprocket wheel and a connecting rod connected between the crank arm and the upper frame member.
