Patent ID: 7063428

Claim:
In lightbank apparatus, which includes a collapsible primary shroud mounted on, and extending outwardly from, a frame, wherein the primary shroud is supported in axially and radially extended configuration by a plurality of primary shroud support rods, which are connected at respective proximal ends to the frame and extend along the primary shroud to respective distal ends at a primary distal border of the primary shroud; an improvement comprising: an attachable and detachable shroud extension, which includes: (i) a ring of flexible material having an extension proximal border, which conforms in size and shape to the primary distal border of the primary shroud, and an extension distal border at a distance spaced axially outward from the extension proximal border, said extension distal border being larger in circumference than the extension proximal border; (ii) a plurality of extension rods positioned in circumferentially spaced relation to each other around the shroud extension such that each of said extension rods extends from a proximal end at the extension proximal border to a distal end at the extension distal border; (iii) extension rod connectors, which are configured to connect the proximal ends of the extension rods axially to the distal ends of the primary shroud support rods in a detachable manner; and (iv) mating border connectors on the extension proximal border and the primary distal border which are configured to connect the extension proximal border to the primary distal border in a detachable manner; whereupon the primary shroud is usable alone for a lightbank of a primary size, but, with the shroud extension attached is also useable alternatively for a lightbank that is larger axially and radially than the primary size.
