ABSTRACT:
Three separate embodiments of file drawer fillers are provided in the invention. One filler is partially self-adjusting and two fillers are completely self-adjusting in length to accommodate variations in the number of documents in a file or desk drawer. A first embodiment is a substantially rectangular panel strip transversely fan-folded to form several connecting smaller panels of equal size. The folds are aligned horizontally with the two end panels positioned vertically to support filed materials in a vertical position. A second embodiment is provided in an elongated enclosed bellows endwardly connected to vertical end panels. The end panels form the document support surface. The bellows portion of the device is affixed with an air valve which allows the release or intake of air to adjust supporting length of the bellows. A third embodiment entails a horizontal compression spring endwardly attached to two vertical end panels with the end panels providing document support surfaces.
