摘要： A lightweight, portable apparatus which is foldable for storage and stackable when folded, and deployable to provide stable support for a planar target member for target shooting purposes. The apparatus has a generally box-like main frame of tubular members, including skid rails extending longitudinally of the main frame, upper longitudinal rails generally parallel to the main frame skid rails, upright members connecting the main frame skid rails and the upper longitudinal rails at least at the forward and rear ends of the main frame, and lower cross-bars extending transversely to and interconnecting the main frame skid rails. The apparatus also includes a stabilizer frame having a pair of stabilizer skid rails spaced apart a distance greater than the width of the main frame and having a length approximately equal to the length of the main frame skid rails, a plurality of cross-bars interconnecting the stabilizer skid rails, and at least one upright member extending upwardly from each stabilizer skid rail at a forward end of the stabilizer frame. The stabilizer frame upright members are pivotably connected to respective upright members at the rear end of the main frame. When the planar target is removed, the apparatus may be folded for storage by pivoting the stabilizer frame upwardly until the stabilizer frame cross-bars rest across the upper longitudinal rails of the main frame. One folded apparatus may be stacked on top of another, with the main frame skid rails of the upper apparatus nested between the stabilizer skid rails of the lower apparatus.
