The mechanism is particularly for a door with a hinging side-section. This section is coupled to a supporting body with roller bearing working on a profiled rail supporting the door, and has a motor bracket pivoting on the vertical hinged axis of the side section. The bracket has a motor-driven pinion and a feed pinion meshing with a rack running along the rail. The motor-bracket (10) is coupled to a roller bracket (6) likewise hinging on the hinge axis (9), and which extends under the rail (1). This forms a bearing for a guide roller (7) engaging in the rail and situated exactly opposite the feed pinion (16). The body (5) with supporting roller (3) can form a rigid unit with the bracket, while the latter and the motor-bracket can hinge independently on the axis, being coupled to each other by a detachable locking bolt (13). |
