Abstract:
A swing device and method of swinging a swing, by the person in the swing, including an arrangement adapted to transmit a downward arm force, from the person swinging to a forward and backward swinging motion. The device includes at least two hanging handles, length adjustable and guided which at its end has a means to grip by handle. Pulling on either handle at alternate times will deliver force to a force translation apparatus, which will redirect the energy from the handles into forces on the upper portion of the swing chains to pull the swing forward and backwards.
