Claim Text:
1. An adapter clip for use in a ring binder or the like, adapted to hold without movement and retain in place folded sheet music within said ring binder without modification to said music, comprising a wireform of drawn round wire, said wireform having: (a) a straight central portion of predetermined length, said straight predetermined length being equal to or greater than the height of said sheet music; (b) a substantially U-shaped return bend at each end of said predetermined straight portion, each of said two bends being on the same side and in the same plane as one another, and each said bend having a predetermined bend radius; (c) each said substantially U-shaped bend returning inwardly as a second straight portion of second predetermined length; (d) each said second straight portion ending in a closed tangential ring coplanar with said substantially U-shaped bends, said closed rings looping away from said straight central portion; (e) each of said two coplanar closed tangential rings having a diameter selected to fit freely onto the outermost two rings of said ring binder; (f) each of said second predetermined lengths of said second straight portions selected to place said closed tangential coplanar rings equidistant with said two outermost rings of said ring binder, such that said wireform may be mounted on said two outermost rings of said binder and swung freely thereabout; (g) each of said two substantially U-shaped bends having a bend angle of greater than 180 degrees, said greater bend angle selected to place each said closed tangential coplanar ring in forcible residual compressive contact against said straight central portion of said wireform, to provide thereby a pair of singular pinch points therebetween, whereby sheets of paper inserted through each of said two singular pinch points are held without movement and retained in position by said pinch points.
