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.

L'invention porte sur un dispositif de poignée pour actionner des portes, des fenêtres et similaires, comprenant un premier élément, qui peut tourner autour d'un axe de rotation, un second élément et un dispositif d'accouplement qui est relié aux premier et second éléments et conçu pour permettre ou empêcher de façon sélective une rotation relative autour de l'axe de rotation entre les premier et second éléments, le dispositif d'accouplement comprenant un élément d'accouplement externe (3, 50) et un élément d'accouplement interne (5, 31), qui est reçu de manière concentrique et de façon à pouvoir tourner autour de l'axe de rotation, dans l'élément d'accouplement externe. Le dispositif de poignée comprend au moins un élément d'engagement (20), qui est déplaçable radialement dans l'élément d'accouplement interne (5, 31), et un élément d'activation (12, 60) qui est reçu dans l'élément d'accouplement interne et axialement déplaçable dans celui-ci, parallèlement à l'axe de rotation. L'élément d'engagement et l'élément d'activation ont des surfaces de contact interagissantes (12b, 12c, 61, 63) afin de presser l'élément d'engagement dans une position se projetant radialement pour un engagement simultané avec les éléments d'accouplement interne et externe, pendant un déplacement axial de l'élément d'activation.
