ABSTRACT:
A scaffold assembly for supporting members of a musical choir in a standing arrangement simulating the appearance of a traditional Christmas tree is disclosed. The scaffold assembly is arranged in tiers of horizontal standing boards rising one above and one behind another in stairway fashion from a base tier of standing boards to an uppermost tier of standing boards. The horizontal standing boards of each tier are arranged to form a segmented arc in a plane which is transverse to the vertical axis of the scaffold assembly. The tiers are stabilized by a plurality of horizontal support beams and upright support posts and a central stanchion. A first set of horizontal support beams project radially outwardly from a central plate, which is attached to the central stanchion, to the underside of the standing boards, and are attached to the respective support posts at the perimeter of selected ones of the tier. Each tier includes a second set of horizontal support beams, which are connected to respective support posts at one end, and extend beneath the standing boards to provide support therefor. Stair steps are provided along each side of the assembly and chest rails are provided in a segmented arc pattern corresponding with the segmented arc defined by the respective standing boards of each tier.
