<p>The box or rack accommodates documents or similar items contained in flat sacks. It has transverse beams (7) from which horizontal bars (16) extend toward the front for virtually its full depth. The sacks (15) fit over these bars by means of slots formed in the top of them. The beams can be rectangular-section tubes, while the ends of the bars are bent over at right angles and secured to their top and bottom faces. The free ends of the bars can slope upwards. At the beam ends there can be transverse portions (8) resting in supports (1), forming a U-shaped frame, the bars being parallel to the arms of the U.</p> |
