ABSTRACT:
A recreational apparatus for propelling two or more persons with respect to each other. A handle is attached to each of opposite ends of an extendable link. The extendable link extends or stretches from an equilibrium position to an extended length upon application of an outward force applied to the extendable link. The outward force has an outward force component directed outward along a longitudinal axis of the extendable link. After release of the outward force, the extendable link returns to its equilibrium position with an inward force. The inward force has an inward force component equal in magnitude and opposite in direction to the outward force component for accelerating a first user with respect to a second user. The recreational apparatus also has a shield mounted around the handle for protecting each user's hands in the event the opposite user intentionally or unintentionally releases the handle when the extendable link is under tension forces.
