<p>On a beam (1), which constitutes the body of the sheet material holding device, are slidingly mounted, by means of prismatic coupling with wings (1a) of the beam profile, one or more hook brackets (2) for hanging the beam (1) to mounting bars (5) which are disposed in suspension filing systems and, respectively, at least two sheet material holding forks (3) by prismatic coupling with wings (1b) opposite to the wings (1a) with respect to the core (1c) of the beam profile.</p><p>Locking means consisting of a screw, apt to lock the hook bracket (2) to the beam (1), are on each bracket, and retaining means, generally by friction, are provided between each holding fork (3) and the beam, to prevent the forks from indesirably moving under the effect of the weight of the bound sheet materials.</p> |
