ABSTRACT:
A Y-shaped support structure is movably attached at its two arms to a track vertically attached adjacent the face of a building. Two of the arms of the Y-shaped support structure are movably engaged in a slot in the track and a net is suspended between the support structure and a similar support structure on a parallel track. The support structures with attached net can be raised by removing the supports from the upper arms of the Ys and sliding the ends of the upper arm upward while folding the net toward the building, then supporting the upper arms while the lower arms are raised while simultaneously unfolding the support structure outward, and finally supporting the bottom arms of the Ys. The support structure is lowered by reversing the procedure for raising it.
