Abstract: A multi-panel sliding door includes a main drive to directly move a leading door panel and includes an auxiliary drive to smoothly accelerate a lagging door panel. In some embodiments, the auxiliary drive includes a hanging weight that urges the lagging panel to its open position. In another embodiment, the auxiliary drive includes a belt and sheave arrangement attached to the lagging panel. The leading panel is coupled to move the belt around two sheaves as the leading panel moves relative to the lagging one. The belt's movement is limited by a bumper that is attached to one point on the belt and is constrained to travel between one of the sheaves and a fixed stop attached to a wall or the track. As the main drive starts moving the leading panel to its open position, the relative movement between the two panels causes the belt to move the bumper up against the fixed stop. From there, continued opening movement of the leading panel continues rotating the belt around the sheaves.

Abstract: The invention relates to a door or gate closing mechanism having essentially rectangular closing elements disposed horizontally and in parallel to one another which are movable in manner overlapping one another. The closing elements are driven in such a way that the second closing element is travelled at double the speed of the first and the third at three times the speed of the first and the last at a speed corresponding to the speed of the first closing element multiplied by the number of closing elements. Thus, only the bottom-most closing element is travelled over the full height at maximum drive speed during the opening or closing of the door while the remaining closing elements have to be travelled at a correspondingly lower speed over correspondingly shorter distances. In this way, overall a favourable energy balance is produced during the opening and closing of the door closing apparatus in accordance with the invention.
