Abstract
Abstract 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.

Claim 1
Independent Claim
412 words
A music stand comprising: a tripod base adapted to be located on a supporting surface, said tripod base having an upper end spaced furthest from the supporting surface; a substantially rectangular center panel having a backside and a front side, said planar center panel having an upper edge and a lower edge with said lower edge being located nearest said tripod base, said planar center panel having a right side edge and a left side edge, said upper end of said tripod base being connected to said backside; a right side panel pivotally connected to said right side edge, a left side panel pivotally connected to said left side edge, both said right side panel and said left side panel being independently movable between a position in substantial planar alignment with said center panel to a position substantially perpendicular to said center panel, both said right side panel and said left side panel having a bottom edge, said bottom edges being misaligned from said lower edge so when said right side panel and said left side panel are in said position substantially perpendicular to said center panel said bottom edges are located nearer said lower edge than said upper edge and actually directly adjacent said lower edge; a center shelf member being pivotally mounted to said lower edge of said center planar center panel, said center shelf member being constructed of thin sheet material and being capable of assuming a substantially right angled position relative to said front side; a right side shelf member being pivotally mounted to said bottom edge of said right side panel, said right side panel having a front surface, said right side shelf member capable of assuming a position substantially perpendicular to said front surface, with said right side shelf member in said position substantially perpendicular to said front surface and said right side panel being substantially perpendicular to said center panel a portion of said right side shelf member overrides said center shelf member; and a left side shelf member being pivotally mounted to said bottom edge of said left side panel, said left side panel having a front surface, said left side shelf member capable of assuming a position substantially perpendicular to said front surface, with said left side shelf member in said position substantially perpendicular to said front surface and said left side panel being substantially perpendicular to said center panel a portion of said left side shelf member overrides said center shelf member.
Claim 2
Dependent Claim
412 words
A music stand comprising: a tripod base adapted to be located on a supporting surface, said tripod base having an upper end spaced furthest from the supporting surface; a substantially rectangular center panel having a backside and a front side, said planar center panel having an upper edge and a lower edge with said lower edge being located nearest said tripod base, said planar center panel having a right side edge and a left side edge, said upper end of said tripod base being connected to said backside; a right side panel pivotally connected to said right side edge, a left side panel pivotally connected to said left side edge, both said right side panel and said left side panel being independently movable between a position in substantial planar alignment with said center panel to a position substantially perpendicular to said center panel, both said right side panel and said left side panel having a bottom edge, said bottom edges being misaligned from said lower edge so when said right side panel and said left side panel are in said position substantially perpendicular to said center panel said bottom edges are located nearer said lower edge than said upper edge and actually directly adjacent said lower edge; a center shelf member being pivotally mounted to said lower edge of said center planar center panel, said center shelf member being constructed of thin sheet material and being capable of assuming a substantially right angled position relative to said front side; a right side shelf member being pivotally mounted to said bottom edge of said right side panel, said right side panel having a front surface, said right side shelf member capable of assuming a position substantially perpendicular to said front surface, with said right side shelf member in said position substantially perpendicular to said front surface and said right side panel being substantially perpendicular to said center panel a portion of said right side shelf member overrides said center shelf member; and a left side shelf member being pivotally mounted to said bottom edge of said left side panel, said left side panel having a front surface, said left side shelf member capable of assuming a position substantially perpendicular to said front surface, with said left side shelf member in said position substantially perpendicular to said front surface and said left side panel being substantially perpendicular to said center panel a portion of said left side shelf member overrides said center shelf member.
Claim 3
Dependent Claim
50 words
The music stand as defined in claim 1 wherein: the width of said right side panel being substantially equal to the width of said left side panel, the combined widths of said right side panel and said left side panel being substantially equal to the width of said center panel.
Claim 4
Dependent Claim
48 words
The music stand as defined in claim 2 wherein: when said right side panel and said left side panel are in said planar alignment position said right side panel and said left side panel being slightly inclined relative to said front side thereby forming a slightly concave configuration.
