Abstract: A ride-along vehicle may include both handles and foot rests each capable of providing power to the pump arm. An improved pumper arm and steering mechanism may include a pivot joint that is provided by rods, pins, or bolts attached to opposite sides of the pumper arm. The universal joint between the steering arm and the pumper arm can be aligned with the center of the pivot point to prevent rocking of the steering arm as the pumper arm is actuated.

Abstract: A strapping material dispenser may include a housing having a hinged door. A roll of strapping material may be received within the housing and fed into contact with an advancing wheel. A portion of the advancing wheel may extend outside the housing to be contacted by a user. Rotation of the advancing wheel dispenses strapping material from the dispenser. A cutting mechanism may be arranged within the housing to cut the strapping material once the desired length has been dispensed from the dispenser. A motor and digital control circuit may be provided to electronically control the advancing wheel and therefore the dispensing of material from the dispenser.

Abstract: A hybrid pump-action vehicle and therapy device may include a pumping arm attached to a lower pump-action assembly. As the pumping arm is actuated, the lower pump-action assembly moves forward and rearward in response to the pumping action and powers movement of the vehicle. The lower pump-action assembly may be releasably connected to the pump arm so that the pump arm can be disengaged from the pumping action but still be usable for steering. A motor may also be provided to provide assistance or full power to the vehicle based on a user-selectable amount of assistance. And finally, the vehicle may be configured such that it can be collapsed to a fraction of its operating footprint to enable easy transport and storage.

Abstract: A ride-along vehicle may include a spring/chain guard that covers a spring and chain assembly and provides an attachment point for the spring. The guard may have a narrow portion that covers and helps retain the chain on a sprocket as well as a wider portion that covers the spring. In another embodiment, the spring can be connected to a fulcrum that has a chain retention pulley, gear, guide, or wheel that keeps the chain tight in loop to improve the pump-action operation of the vehicle. An improved pumper arm and steering mechanism may include a pivot joint that is provided by rods, pins, or bolts attached to opposite sides of the pumper arm. The universal joint between the steering arm and the pumper arm can be aligned with the center of the pivot point to prevent rocking of the steering arm as the pumper arm is actuated.

Abstract: A human-powered, ride-on vehicle, includes a main longitudinal frame member having a steering/drive mechanism mounted thereon for oscillating movement; a driven rear wheel having an axle, a rear sprocket operatively fixed to the rear wheel for coastable engagement therewith; a pair of spaced apart, steerable front wheel located adjacent the other end of the main longitudinal frame member and operatively connected to the steering/drive mechanism; wherein, the steering/drive mechanism include: a teeter arm mounted to the main longitudinal frame member intermediate the ends thereof for pivoting movement in a fore direction and an aft direction; a drive mechanism including first and second drive linkages, wherein the first drive linkage provides a motive force to the driven rear wheel during a first power stroke and the second drive linkage provides a motive force to the driven rear wheel during a second power stroke, and wherein, for equal movement of the teeter arm in the for and aft directions, the motive forc

Abstract: A ride-on vehicle having a longitudinal axis includes a body; a rear axle having a crank portion therein and rotatably secured to the body; a pair of spaced-apart driven rear wheels eccentrically fixed to the rear axle; a forward crank rotatably secured to the body and driven by a vehicle rider; and a shaft extending between the rear axle crank portion and the forward crank; wherein rotation of the forward crank results in a driving force being transmitted through the shaft to the rear axle crank portion, thereby causing the vehicle to move along its longitudinal axis and wherein the body oscillates vertically when the vehicle moves along its longitudinal axis.

Abstract: A ride-on, human-powered vehicle a frame, which is integrally formed with the body of the vehicle. A front axle includes spaced-apart, steerable axle elements located on either side of the front end of the frame, each steerable axle element having a wheel rotatably mounted thereon A steering/power mechanism is mounted on the frame for oscillating motion relative to the frame that includes a steering shaft for steering the front wheels having a handle bar located at the upper end thereof. Foot rests are located at the lower end of the steering/power mechanism. A chain extends from the steering/power mechanism to the rear axle. A combination of the handle bar and the foot rests allow the rider to power the vehicle through the use of arms and legs simultaneously.

Abstract: The vehicle and drive mechanism includes a vehicle frame having at least one steerable wheel carried thereon, an axle mounted on the frame and at least one driven wheel mounted on the axle. First and second ratcheted gears drivingly disposed on the axle to produce rotary motion of the axle when each gear is rotated in a first direction and coast relative to the axle when rotated in a second, opposite direction; an oscillating handle/footrest assembly operable to provide a driving force for the driven wheel and to provide braking action on a wheel.

Abstract: A drive mechanism for a human-powered vehicle is disclosed. The vehicle has a frame, plural wheels and linear motion generating mechanism, which is operable by a human being, for generating substantially linear, oscillating motion. A motion converting device is provided for converting the oscillating motion into rotary motion. A mechanism for transmitting the rotary motion to the driving wheels is provided.
