ABSTRACT:
A push-pull swing having a frame suspended from an elevated vertical support by a first pair of parallel ropes and a second pair of ropes spaced parallel to and vertically outward from the first pair. The frame comprises a vertical member having a plurality of vertically spaced horizontal openings to which is pivotally connected a horizontal member having a plurality of openings spaced inwardly from the outward end and at least one outermost vertical opening disposed near the outward end to receive the second pair of ropes which are secured to the horizontal member. A seat rest is removably and adjustably fastened to the horizontal member to adapt the swing to various sized persons and selectively control the amount of bending by the user to operate said swing. A vertically spaced apart upper and lower cross member extends outwardly equally from each side of the vertical member to receive the first pair of ropes which are secured to the lower cross member. A pair of back rest members are adjustably mounted adjacent the horizontal member on the second pair of ropes for vertical movement thereon for selectively supporting the back of the user.
