Abstract: A moving slide has a pair of flexible curtains mounted to its front and rear surfaces, the curtains being attached at opposite ends to front and rear support posts mounted to a base. The support posts have upper and lower pulleys. A cable is connected to the front of the slide and runs in this fashion: first horizontally across the top pulley, thence to the lower pulley, thence to the other support post, thence upwardly and finally around to the horizontal portion which connects to the rear of the slide. The cable is tensioned to a predetermined load which remains constant throughout the slide travel as the front and rear horizontal portions of the cable move. The flexible curtains are suspended from, but are not rigidly attached to, the cable. Thus, as the curtains expand and contract, the moving horizontal portions of the tensioned cable ride smoothly through the curtains, maintaining curtain support.
