FILE MECHANISM HAVING A DOUBLE LEVER

The file mechanism comprises a base plate (1) with a pair of stable pins (11, 12), which are firmly attached thereon, as well as two pivotable pins (21, 22), which may be pivoted and pressed towards said stable pins (11, 12) by means of swiveling an actuating lever (3). The purpose of the invention is to assure, that despite to minimum possible modifications of an existing mechanism said actuating lever (3) should be maintained in such position that each user could transpose the sheets, which are stored in such a document file. The invention proposes a double i.e. two-part lever (3), which consists of a primary part (31), which is by means of appropriate pivot joint (30) pivotally attached to the cantilever (13) on the base plate (1), as well as of a secondary part (32), which is pivotally attached to said primary part (31). An actuating member (35', 35') is foreseen on the primary part (31) at a corresponding distance apart from the pivot joint (30), which is intended to cooperate alternatively either with an elevation (251) or with an inclination (252) on the supporting member (250) on the intermediate section of the clamping set (2).
