Abstract
A rotating drive mechanism for operating the wing of a swinging door, especially of a vehicle. The wing is articulated by pivoting arms to a rotating post, which it rotates along with. When the door is closed, the wing can be raised by axial displacement of the post into a locked position, where locking components on the stationary door frame and on the wing of the door engage each other. The post is driven by a strictly linear mechanism that is controlled by pressure medium and its linear motion is converted into a rotation by a helical transmission. Certain drawbacks are elminated by the improvement wherein the rotating post is coupled to the helical transmission in such a way that, at least while the wing of the door is closing, the post cannot rotate in relation to it but can move axially and, once the post has attained a specified limit of rotation while the wing of the door is closing, the linear drive mechanism will be additionally directly coupled axially to the rotating post in such a way as to lift it.
