Abstract:
A cable loop is supported around each corner by a rotatable cable support with horizontal pulleys or other cable engaging device on the ends of spokes around the rotatable cable support, A central cylinder rotatably supported by a vertical rod may support the spokes or a pair of concentric rigid rings with the spokes piercing the rigid rings radially, The outer rigid ring may ride or a circular groove on roller bearings or the inner rigid ring may ride on a vertical rod, On straight cable runs, the trolley with the attached leash rides on a trolley vertical pulley wheel over the cable on the straight sections of the cable, At the corners, the trolley rides with one or two or four additional vertical pulley wheels on a single or double curved track below the rotatable cable support. The trolley rides around the curve inbetween two adjacent horizontal cable engaging device which support the cable around the turn and maintain the cable in a curved configuration, The rotable cable support is protected by a casing with flared sides on the cable openings to guide the trolley into the casing, Each protruding edge of track is ramped up into the casing to guide the pulley wheels onto the tracks, The tracks may be curved metal runners supported by brackets or curved cable supported by the casing.
