Abstract: An attachment for use with common porch swings and the like which includes a foldable platform that not only serves as a foot rest but also provides means by which a rider can, with a small amount of effort, propel the swing from rest to a gentle swinging motion. In addition to the platform, the attachment comprises a supporting structure and a pair of flexible members from which portions of the platform proximate its rear and front edges, respectively, are suspended when the platform is fully extended.The attachment transforms foot pressure as it is being applied to straighten the platform for use as a foot rest into a force tending to propel the swing forward. Only a slight pressure is required to set the swing in motion. The action of unfolding the platform is coupled with an increase in tension on the flexible members supporting the platform to greatly magnify the non-vertical component of the force supplied by the rider's foot on the platform.
