ABSTRACT:
The manually releasable stop device permits unimpeded swinging of the window within a limited angle of rotation between the closed and partially open window. After releasing the stop device further swinging of the window is permitted beyond the limited angle of rotation. The stop device comprises two cooperating stop members (25, 26) which are fastened to respective support members (14, 18) in the window hinge which are pivotable relative to each other. A first stop member is constituted by a stop element (26) fixedly fastened to the one support member (14), and the second stop member is constituted by a self-locking catch element (25) fastened to the other support member (18). The catch element cooperates with a positive control mechanism (26, 32, 37, 39) in the pivotal region of the window within the limited angle of rotation. In the pivotal region the positive control mechanism is adapted to forcibly control the catch element (25) to engage with the fixedly fastened locking element (26), while the catch element in the pivotal region is designed for limited movement of the catch element relative to the fixed locking element.
