Filing device for papers

Claim 1

A filing device comprising a ring binding mechanism for attachment to the inside of a protective file cover having upper and lower edges, said ring binding mechanism having a sprung cover, ring carrying elements, and ring components carried pairwise by said ring elements for rocking movements thereby allowing said ring binding mechanism to be opened and closed, a slide disposed at each longitudinal end of said ring binding mechanism, each of said slides being slidably mounted for limited longitudinal displacement along said ring binding mechanism between an extended operative and a withdrawn inoperative position, and a locking element on said slide engageable with said ring carrying elements to secure said ring components of said ring mechanism against opening when said slide is displaced to said extended operative position, said locking element being disengaged from said ring carrying elements when said slide is disposed in said withdrawn inoperative position such that said ring binding elements are free to be opened, suspension means, mounting means mounting said suspension means on said slide and providing for relative movement between said suspension means and said slide, said suspension means being movable relative to said slide to an extended position, said suspension means having a support portion extending beyond the corresponding longitudinal end of said ring mechanism and beyond said edges of said protective file cover when said slide is in said extended operative position and said suspension means is in said extended suspension position, thereby enabling the device to be suspended from spaced carrier rails of a file carrier, said suspension means being movable relative to said slide to a retracted non-suspension position disposed substantially within said protective file cover when said slide is in said withdrawn inoperative position.
