A portable swing system is provided for securing to a support, such as a pole or tree. The system comprises a vertical member adapted to be secured to the support and a horizontal member connected to the vertical member by a hinge. A swing depends from the horizontal member. Adjustable support bars are secured to the horizontal member and the vertical member. The adjustable support bars provide support during the swing cycle through alternating tension/compression cycles, depending on which side of the horizontal member the swing is located. The adjustable support bars may be moved along the vertical and horizontal members to maintain the horizontal member in a parallel relationship with the ground. |
