<p>The device for the opposing movement of two sliding doors (1, 2) contains a motor-driven pivoting lever (8) which is connected in an articulated manner via an arm (7) to lazy tongs (9). These bring about a transmission of movement. The two sliding doors (1, 2) are each fastened to an endless chain (5) guided around deflecting rollers (4), in such a way that they are connected in terms of movement in opposite directions. As a result of this design, a relatively high speed can be selected in the middle range of movement, whilst the sliding-door wings approach the end positions at reduced speed. <IMAGE></p> |
