<p>There is disclosed a device for retaining a stack of hole-punched papers in a file, e.g. an arch lever mechanism for an arch lever file. The device comprises: a base (10); at least two loops (14) secured to and extending upwardly from the base for engaging the punched holes in the papers, each loop having a first "L"-shaped section (16) for holding the papers when the file is closed and a second arched section (18), whereby papers on the top of a stack can be slid over the first section and retained on the second section so that papers lower down the stack can be exposed; and a mechanism for holding the first and second sections in a closed position in which the first and second sections form a closed loop and an open position (as shown) in which the first and second sections are separated to allow papers to be added to, or removed from, the loops. The horizontal limb of the L"-shaped section (16) is secured to, and extends outwardly from, the base (10) and in this way, can be firmly attached to the base. The other limb is straight (thereby easing the addition and removal of papers) and slopes backwardly. <IMAGE></p> |
