ABSTRACT:
A notebook insert for use in a notebook that has a front cover and a back cover hingedly connected to an elongated spine where the spine has either at least two axially-aligned, openable rings evenly spaced longitudinally along the spine or a helical coil. The notebook insert includes a C-shaped frame and a rectangular support. The frame has a center portion and a pair of substantially equal-length arms, where the center portion has a plurality of openings near one edge for receiving the notebook rings and/or a plurality of catches for projecting through the loops of the coil. The support is pivotally connected to the frame by at least two axially-aligned, snap-together journals. The outer bearing surface of each journal is defined by the inner surface of a cylindrical depression located in a protrusion from one of support surfaces, where the cross section of the cylindrical depression forms an arc greater than 180.degree.. The inner bearing surface is the surface of a cylinder connected between the opposite edges of a notch in the remote end of one of the arms.
