ABSTRACT:
A drive apparatus (5) is proposed, consisting of a drive casing (12) and a gear casing (19), in which the two casings (12, 19) are screwed to one another in a centered position and to the frame transverse component (2) with the incorporation between them of a plane wall of the front transverse frame portion (2) of a guide frame (1). The drive casing (12), preferably injection moulded in one piece from a wear-resistant, thermoplastics material, guides two drive cables (8, 9) with guide channels (15, 16) slender in the central portion (15) over such a length that the drive cables (8, 9) can emerge at both ends virtually free of lateral pressure from the drive casing (12) and enter the drive cable guides of the frame transverse portion (2). The drive casing (12) makes possible sliding movements of the drive cables guided with low radial clearance without noise caused by joint positions. As a result of the special formation of the drive casing (12) and of the gear casing (19) cooperating therewith, the drive apparatus can be mounted at low expense reliably and automatically centered, a drive pinion (20) situated in the drive casing (19) coming into engagement with the drive cables inside the drive casing (12).
