Hanging support for vertical documents - has inverted U=section with self locking clamping roller

摘要

The document support consists of a folded metal section in the form of an inverted U with equal sides. The bottom edges of one side (1) is turned out to facilitate the insertion of the document. The bottom edge (3) of the other side (2) is folded inwards to retain the roller (4). The roller is introduced through the end of the section. When the document (5) is inserted the roller is lifted. The roller clamps the document when it drops back to the lower position and wedges on the turned-in edge. The roller is lifted in order to release the sheet.
