A collapsible bookrack, for adding onto an existing bookshelf, comprising:
- a plurality of rectangular bottom spacers, each having (1) a front edge, (2) a rear edge, (3) two opposed side edges, and (4) bottom fastening means disposed along each of the side edges;
- said bottom spacers being disposed horizontally side by side,
- a plurality of identical flat dividers each disposed vertically above abutting side edges of an adjacent pair of said bottom spacers, each of said dividers having (1) a top edge, (2) a front edge, (3) a bottom edge, (4) divider/bottom-fastening means, disposed along the bottom edge, configured to engage the bottom-fastening means, whereby abutting side edges of an adjacent pair of said bottom spacers may be removably fastened to the bottom edge of a corresponding one of said dividers, (5) a rear edge, and (6) divider/rear-fastening means disposed along the rear edge, and
- a plurality of rear spacers each having (1) a top edge, (2) a bottom edge, (3) two opposed side edges, and (4) disposed along each of the side edges, rear-fastening means configured to engage the divider/rear-fastening means of said dividers whereby abutting side edges of each adjacent pair of said rear spacers may be removably fastened to the rear edge of a corresponding one of said dividers;
- said rear spacers being disposed vertically side by side, each located above but not directly fastened to the rear edge of a corresponding one of said bottom spacers,
- the divider/bottom-fastening means of each of said dividers being contained within a cavity along the bottom edge of the divider and the divider/rear-fastening means being contained within a cavity located along the rear edge of the divider, such that assembly of said bottom spacers requires the bottom-fastening means to be inserted into the cavities in the bottom edges of said dividers to a semi-engaged position from which the dividers must be shifted forward to a fully-engaged position, and assembly of said rear spacers together with said dividers requires the rear-fastening means to be inserted into the cavities in the rear edges of said dividers to a semi-engaged position from which the rear spacers must be shifted downward to a fully-engaged position;
- whereby, when the bookrack is assembled, all of the fastening means become fully enclosed, and all of said dividers and spacers present completely smooth surfaces with no protrusions inside or outside the bookrack, thus enabling the bookrack to nest unobtusively and space-efficiently into an existing bookshelf to provide the capability of supporting soft-cover booklets and the like effectively in an upright position.
