window or door fittings comprising at least a first attachment part (2) and a second attachment part (3),where each component (2, 3, 4,10) consists of at least one column rail (15, 16, 22, 24) and a column rail (15, 16, 22, 24) movable (5, 6, 7, 8, 9, 13), with the drive rods (5, 6, 7, 13) connected via a coupling point (23, 25) attached to the drive bar and the coupling point (23, 25) consists of two coupling lines (21, 5),where the first part of the coupling consists of a gear section running along a section (14) on the longitudinal narrow side of the one gear bar (6) of the first gear section (2) and the second part of a U-shaped coupling shoe (14, 21) embracing a complementary gear section (14) the other drive bar (6, 13) of the second attachment (3), where the coupling line is in a coupling position opposite the propelling bar (5) covering the propelling column (24), while the second attachment (20, 21) is in excess of the propelling section (15, 16),where the second fitting part (3) has a angular changeover channel for a power transmission link, characterized by the fact that the changeover channel (11, 12) is attached to two column sections located in the corner area (15, 16) and the column sections (15, 16) and the legs of the changeover channel (11, 12) at an angle to each other which is less than 90's.
