ABSTRACT:
A connecting rod gearing for windows, doors, etc. having two oppositely shiftable connecting rods under a cover rail. The rotational plane for the toothed rim of a pinion and the plane of motion of the engagement toothings which mesh therewith on two thrust links lie in the cross-sectional area of the housing usually occupied by the cover rail so that the crown (addendum) circle diameter of the pinion can correspond to the complete cross-sectional width of the cover rail. This large pinion diameter results in correspondingly large adjustment differences for the two oppositely shiftable thrust links for a given angle of rotation of the pinion.
