Abstract: Described is a wind-up ride on toy with wind-up mechanism to propel a rider. The ride on toy comprises a body portion having a seat portion. A first axle is rotatably connected with the body portion, while a pair of wheels are connected with the first axle. The wind-up mechanism has an elastic band and a rotatable spool. The elastic band is fixed at a first end within the body portion and is attached with the rotatable spool at a second end. Additionally, the rotatable spool is operably connected with the first axle, such that winding the elastic band around the spool causes the elastic band to transition from a relaxed state to a stretched state and, upon allowing the elastic band to return to the relaxed state, the spool rotates the first axle and pair of wheels, thereby causing the wind-up ride on toy to propel forward.

Abstract: Embodiments disclosed herein relate to exercise machines. In some embodiments, the device may include a resistance adjuster configured to adjust the difficulty of an exercise performed on the exercise machine. Particularly, the exercise machine may include a knob configured to modify the resistance in even steps. The exercise machine also may include functional components, such as pulleys, for transmitting a drive force from a user to a resistive body. The functional components may be operatively connected via one or more belts. In some embodiments, the exercise machine may include one or more belt tensioners to regulate the tension of the one or more belts.
