<p>Handle device for doors, windows etc, comprising a first rotatable element (1), and a second element (3), and a coupling device. The coupling device comprises an axially movable activating member (30), and at least one engaging member (51, 52) which can be radially moved between release- and engagement positions. In release position, the first and second (1, 3) elements are mutually rotatable. In engagement position, rotation is prevented. An electric motor (21) moves the activating member (30). It has an output shaft (22) rotatable in two opposite directions and a threaded shaft portion (25) with a first thread. The activating member (30) has a thread engagement portion (34) having a second thread corresponding to the first thread of the shaft (22). First and second spring members (41, 42) press the thread engagement portion (34) towards the threaded shaft portion of the shaft, when the first and second threads are disengaged by rotation of the shaft (22).</p> |
