<p>Handle device for operating doors, windows and the like, comprising a first element, which is rotatable about an axis of rotation, a second element, and a coupling device which is connected to the first and the second element and is designed to selectively allow or prevent relative rotation about the axis of rotation between the first and the second element, the coupling device comprising an outer coupling member (3, 50) and an inner coupling member (5, 31), which is concentrically accommodated, rotatable about the axis of rotation, in the outer coupling member. The handle device comprises at least one engaging member (20), which is radially displaceable in the inner coupling member (5, 31), and an activating member (12, 60) which is accommodated in the inner coupling member and axially displaceable therein, parallel to the axis of rotation. The engaging member and the activating member have interacting contact surfaces (12b, 12c, 61, 63) in order, during axial displacement of the activating member, to press the engaging member into a radially projecting position for simultaneous engagement with the inner and outer coupling member.</p> |
