发明名称 ROLLER-SHUTTER-CABINET
摘要 <p>A cabinet comprises a cabinet frame (2) and a roll front (1) to be opened in the upward direction. At least two springs (6, 7, 8, 9) engage at the roll front (1), these springs being attached with their other ends at the cabinet frame and having mutually different spring characteristics and/or different tension. The sum total of the forces exerted by the springs (6, 7, 8, 9) on the roll front (1) compensates,in any position of the roll front (1), essentially the weight of the latter.</p>
