Abstract: This invention is a fully collapsible file holder, or collator. It is formed from an assembly of supports. When opened, the supports are separated by about an inch, allowing papers, files, and books to be organized between them. When the collator is not in use, it collapses to the thickness of a fraction of an inch. This is facilitated by the invention's novel design, wherein the supports decrease in size from rear to front. When collapsed, they nest inside one another. The full range of movement is enabled by a novel hinge, formed of two struts in a scissors configuration. The collator folds flat to become so small that it is easily transportable in a satchel or even a notebook. This offers great advantage over the very bulky collators in use today.
