PCT No. PCT/EP89/00226 Sec. 371 Date Dec. 20, 1989 Sec. 102(e) Date Dec. 20, 1989 PCT Filed Mar. 6, 1989 PCT Pub. No. WO89/09322 PCT Pub. Date Oct. 5, 1989.A divided flexible covering (1,2)serves to expose any desired region of a surface or opening while masking the other regions. Two gripping slats (3,10) are located respectively at the beginning of a length of fabric (1 or 2) or at the beginning and end of at least one or two strips (4 or 8), each of which is guided endlessly over four rollers (5,9) or sliding blocks (47). Each length of fabric (1 or 2) is provided with an end piece (7 or 12). The length of the lengths of fabric (1 or 2) is approximately half that of the strips (4 or 8). The end pieces (7, 12) are mutually offset and are provided with a slot (14a) or are attached to a rod (43) provided for the other length of fabric, so that when a covering part (1), for example, is pulled down over the center of the cupboard, the covering part (2) is pulled simultaneously because one end piece (7) entrains another end piece (12) upward in the direction of traction. The operations are indentical in the opposite directions. The gripping slats (3 and 10) and the end pieces (7 and 12) for unattached strips (4 and 8) have slits which ensure frictionless sliding.
