Patent number: 5114111Abstract: A collapsible music stand composed of a plurality of foldable panels which are mounted on a tripod base. Sheet music is to be located against the foldable panels. Foldable panels include a center panel with one side panel mounted to the right edge of the center panel and another side panel mounted to the left edge of the center panel. The side panels have bottom edges which are slightly misaligned from the bottom edge of the center panel so that the side panels can be pivoted to rest against the front side of the center panel with the bottom edges of the side panels not interfering with the lower edge of the center panel. The side panels are capable of assuming a substantially aligned position with the center panel with the side panels being slightly inclined so that relative to the front side of the center panel there is formed a slightly concave configuration. Pivotal shelf members are mounted to the bottom edges of the side panel and to the lower edge of the center panel.Type: GrantFiled: March 25, 1991Date of Patent: May 19, 1992Inventor: Kim N. Andrews
