Pivot drive comprises two parallel four-bar mechanisms arranged in a U-shaped frame (1) or a box, each with a drive element (2), one or two coupling elements (3), a driven element (4), a frame (7, 20) laterally or centrally fixed to the U-shaped frame or box, and a linear drive (10) arranged between the two four-bar mechanisms and hinged on one side to the frame or box and on the other side to the drive elements. The component driven by the pivot drive lies outside the two mechanism planes/pivot drive and is laterally connected to the driven element. The four-bar mechanism is designed so that the pivot angle of the driven element is greater than that of the drive element. An independent claim is also included for an alternative pivot drive. Preferred Features: The two drive elements form one component or are rigidly connected to each other. |
