Abstract
A retractable lock for doors is provided that includes a frame mountable on the front side of the door panel for receiving a retractable lever grip. The lever grip is moveable along a release path between a retracted position inside the frame, where it is secured by a locking device, and an actuating position outside the frame. Further rotation of the lever grip along an actuating path transmits into rotational movement of a pinion which drives a locking rod, which is longitudinally slidably guided at the inner side of the door panel by engagement of outer teeth of the pinion at cutouts of the rod.
