ABSTRACT:
The invention is a poolside descending scaffold having an apron bar which is extendable by an apron arm extender fitted into its two end pieces, which are rectangular box girders of light metal or steel. End pieces are affixed to the extender by pad bars with threaded internal pins. The pad rods carry pads which are of sufficient area to prevent rotation of the apron bar. The pads may be simple flat metal pads or may be eccentric blocks or screw pads useful in leveling the apron bar. The apron bar has a weight basket at its distal end and a hinge bracket at its poolside end. The hinge bracket holds a descending bar at a position along its length determined by a pin through one of a set of holes in the descending bar and through holes in the hinge bracket. The descending bar has ladder pins to ease the climb between poolside apron and scaffold plank, and a bumper bar on a threaded pin which can also serve to affix the plank bracket to the descending bar.
