Abstract (en)
1. Device for the clamping of sheets for writing, drawing and similar working support bases, in which overlaps are provided on the support base for parts of the sheets, and also clamping elements, which press the parts of the sheets, which have been pushed underneath the overlap, from below against the underside of the overlap, characterised in that the actuating elements (7, 9) of the clamping elements (6, 8, 12) penetrate through openings in the overlaps (3, 10) to the upper side of the support base (1, 2) and neither the actuating elements (7, 9) nor the overlaps (3, 10) project above the surface of the support base (1, 2).
