Abstract:
1. A folding sheet music stand that provides a sturdy platform for holding sheet music, is adjustable for different heights and orientations and is capable of being folded into a compact package that can be easily carried without damage to said folding sheet music stand comprising: a main shaft; a collar assembly surrounding said main shaft; a first clamp attached to said collar that fixes said main shaft with respect to said collar assembly and allows adjustment of the position of said main shaft with respect to said collar assembly; folding legs that support said folding sheet music stand; leg hinges attached to said collar assembly and said folding legs that allow said folding legs to fold to a compact position and to open to an open position to support said folding sheet music stand; a secondary shaft disposed inside of said main shaft, said secondary shaft having a size that allows said secondary shaft to fit firmly in said main shaft and to slide in said main shaft; a second clamp attached to said main shaft that fixes said main shaft with respect to said secondary shaft and forms an extendable leg assembly that includes said main shaft, said collar, and first clamp, said folding legs, said leg hinges, said secondary shaft and said second clamp; a back sheet music holder having a center folding back plate and side back plates that are attached by hinges to said center folding back plate that allow said side back plates to unfold to an open position to form a flat front surface for placement of said sheet music, and to fold away from said flat front surface to a folded position so that said side back plates are disposed at an angle to said center folding back plate to form an angular opening between said side back plates and said center back plate; flanges formed on said back sheet music holder that form a slot, said flanges having at least one surface that is substantially parallel to said flat front surface; a bottom sheet music holder having a ridge formed along one edge, said ridge having a size and shape that allows said ridge to slide firmly within said slot so as to fix said center back plate and said side back plates in a stationary position to form said flat front surface, said ridge having at least one surface that engages said at least one surface of said flanges that is substantially parallel to said flat front surface so that said side back plates are prevented from folding away from said front flat surface whenever said ridge is engaged in said slot; a shaft tightening hinge attached to said back sheet music holder on a lower portion of said center back plate when said back sheet music holder is extended into a position for use, and to said secondary shaft so that said extendable leg assembly can be rotated in a first direction along a plane and fixed in said position for use so that said back sheet music holder is in a desired orientation, and rotated in a second direction in said plane so that said extendable leg assembly is disposed within said angular opening between said side back plates and said center back plate.
