An actuating device () actuates a shading system with a string element (). An unintended detachment of a first partial structure () from a second partial structure () in the intended use is avoided as much as possible and a detachment of the first partial structure () from the second partial structure () is possible with low forces for avoiding injuries. The actuating device () includes a first coupling element () that in the released position does not mesh with a second coupling element (), and in the locking position, with an interaction of the first coupling element () with the second coupling element (), a detachment of the first partial structure () from the second partial structure () is prevented because of a positive-locking connection between the first coupling element () and the second coupling element ().

Actuating device, especially for a shading system, for actuation with a string element

A device () for fastening a window blind with a window blind end piece (), which has a front surface (), on which is arranged an axis segment (). The axis segment () interacts with a mounting element (), which can be rotated about an axis of rotation () of the axis segment (), for opening and/or closing a holding mount (). An axial guide () is provided, which fixes an axial position of the mounting element () in relation to the axis of rotation () of the mounting element () about the axis segment (). In order to reduce the risk of premature wear and to simplify a change between left-sided or right-sided mounting, the device () has a positioning device (), which is separate from the axial guide (). The positioning device () is provided for the detachable fixing of the mounting element () in at least one rotation position of the mounting element () in relation to the axis segment ().

Device for fastening a window blind

A drive unit for a vertical Venetian blind includes a shared driving element () for the displacing motion and the rotating motion of vertical slats. A differential gear () is provided with a driving element coupled to the shared driving element (), a first driven element () coupled to the first drive means () for the rotating motion of the vertical slats, and a second driven element () coupled to second drive means for the displacing motion of the vertical slats. Displacing motions and rotating motions of the vertical slats can be driven by the shared driving element (). A complete closing of the vertical slats is made possible in both directions of rotation and, at the same time, a hooking up of the vertical slats by means of displacing same in an unsuitable rotating position is prevented.
