The pedal driven swivel toy provides a ride for children which includes a combination of translation and rotation. The toy is suspended from a support structure allowing swinging and rotating motion. A wheel contacting the ground and driven by the child through the use of pedals forces the center of gravity of the toy from a stable rest position to an unstable position thereby inducing rotation and swinging of the toy. The combination of motion is exhilarating for the child and the use of pedals provides exercise for the child while allowing control of operation of the toy.
A rotary and rocking toy device has four bottom seats, four roller wheels, four support frames, and four carriers. The support frames are connected together to form a cross shape. Each roller wheel is disposed on the respective bottom seat. Each support frame is connected to the respective roller wheel pivotally. Each carrier is connected to the respective support frame stably.
A self powered human centrifuge for simulating gravity and providing an aerobic workout as a countermeasure to the adverse physiological effects of prolonged spaceflight. A frame rotates about a stationary shaft located above the head of the rider. Power is provided by the rider via pedals and handles in a bicycle type apparatus. A plurality of gears may be selected using a derailleur and freewheel. A brake may be used to increase resistance and thus workout intensity. A cam and roller device at the foot crankset simulates impact loading of normal earth walking.
