Pipe holder is hinge to base 2, and lock of paper. paper holder is made in form of two clamps located in parallel planes and joined by connecting member 7 and bent from solid piece of wire. Each clamp is formed of two parallel adjacent horizontal sections of wire having form of a part of circumference located in the plane square to base of paper holder. In this case, one end of clamp serving for passing through perforation of sheet of paper formed by bending of wire through 180 deg, and the other end is bifurcated, and its one part passes into connecting member. Version of the paper file has paper holder containing more than two clamps bent from one length of wire and interconnected respectively by connecting members. EFFECT: higher efficiency. 2 cl, 8 dwg |
