Abstract

Die Erfindung betrifft eine Gelenkverbindung zum Umwandeln einer Linearbewegung in eine Schwenkbewegung mit einem linear bewegbaren Betätigungselement (17), mit einem an dem Betätigungselement (17) angeordneten Kugelgelenkkopf (19), wobei der Kugelgelenkkopf (19) zum mindestens teilweisen Übertragen der Linearbewegung des Betätigungselementes (17) auf ein Drehelement (20) mit dem Drehelement (20) verbunden ist. Zur weitgehenden Vermeidung von, insbesondere quer zur Hauptwirkrichtung, auf das Drehelement wirkenden Kräften unmittelbar auf das Betätigungselement sowie zur Erleichterung der Montage und Verringerung des Raumbedarfs ist die Gelenkverbindung dadurch gekennzeichnet, dass das Drehelement (20) an einer örtlich feststehenden Drehachse (21) drehbar gelagert ist, und der Kugelgelenkkopf (19) verschiebbar in dem Drehelement (20) geführt ist.

Figure imgaf001
The invention relates to a hinge connection for converting a linear movement into a pivoting movement with a linearly movable actuating element (17), with a ball joint head (19) arranged on the actuating element (17), wherein the ball joint head (19) for at least partially transmitting the linear movement of the actuating element (17). 17) is connected to a rotary element (20) with the rotary element (20). To largely avoid, in particular transversely to the main direction of action, acting on the rotary member forces directly on the actuator and to facilitate assembly and reduce the space requirement, the hinge joint is characterized in that the rotary member (20) rotatably mounted on a stationary rotation axis (21) is, and the ball joint head (19) slidably guided in the rotary member (20).
