Embodiment Construction

[0042] figure 1 In a simplified plan view, an exemplary embodiment of an opening device 1 for a window, door or similar object is shown, which causes or permits the turning of a rotary flap of the window, door or similar object. The opening device 1 has a first articulated lever 2 as opening scissors arm 3 , and the first articulated lever is mounted there at its one end 4 so as to be rotatable or rotatable about an axis of rotation 5 . on the outer frame 6 which is only partially shown, and the first joint lever is supported at its other end 7 in a rotational manner about a rotation axis 8 on the window, door or window which is only partially shown here On the fan blade frame 9 of similar object. In addition, the opening device 1 has a second articulated lever 10 as a support arm 11 , and the second articulated lever is mounted on its one end 12 so as to rotate about an axis of rotation 13 on the opening. The scissors arm 3, and the second joint lever is supported on the fa...

Abstract

The invention relates to a hinged opening device for a window, a door, or the like, having at least one hinged arm that can be supported so as to be pivotable about a rotation axis, wherein the position of the rotation axis can be shifted by means of a rotatable eccentric, and wherein the eccentric has an anti-rotation locking device. It is provided that the anti-rotation locking device (24; 49) has at least one anti-rotation locking element (46; 51) inserted into at least some areas of a cutout (32; 52) provided in a frontal area (31) of the rotatably supported eccentric (21). The invention further relates to fittings (23) for a window, a door, or the like.

Description

technical field [0001] The invention relates to an opening device for windows, doors or the like, said opening device having at least one hinged lever which is rotatably supported about a rotational axis, wherein the position of said rotational axis can be determined by means of It moves on a twistable eccentric, and wherein said eccentric has a twist-stop device. Background technique [0002] A variety of opening devices of the aforementioned kind are known from the prior art. These opening devices are used to connect a movable leaf frame in a window, door or the like to a fixed outer frame and to cause or permit the turning of said leaf frame, in particular a swivel leaf frame. For this purpose, such opening devices have one or more articulation levers which enable the desired movement of the window. Furthermore, the one or more articulation levers are each mounted rotatably about at least one axis of rotation. For example, a articulated rod is fixed or supported on the...
