ABSTRACT:
A pedal for a pedal driven apparatus, such as a bicycle, moped, or the like, includes a flexible, pliable, strap as of nylon webbing which passes twice over the pedal forming a double loop configuration for strapping the foot of the operator to the pedal. A leaf spring, preferably disposed within the nylon webbing arches over the pedal, generally parallel to its axis of revolution, for holding the loops of the strap in an arched configuration over the pedal to facilitate entry of the operator' s foot. A slideable locking fastener permits the operator to tighten the straps over the foot while pedalling. A holder holds the two straps in side-by-side relation while permitting the strap to slide therethrough for adjustment of the loop size. A gripping member is carried on the loose end of the strap to facilitate pulling thereon. Velcro fasteners are associated with the loose end of the strap and the holder for fastening the loose end of the strap to the holder after the adjustment has been made. The strap is of light weight and disposed such that the total pedal assembly including straps, has a center of gravity relative to the axis of revolution such that the moments exerted on the pedal are arranged to hold the pedal in the horizontal to facilitate entry of the foot.
