Abstract
A window sash (3) is mounted on a stationary frame (2) so as to be only rotatable about a horizontal axis but not tiltable using a lower corner bearing (5) such as is also used for turning-tilting fittings, and using an upper hinge bearing (9), which is connected to the sash via a support arm (11). The support arm (11) is sufficiently flexible in the vertical direction in order to be able to follow the vertical adjustment movements of the sash which are carried out at the corner bearing (5). Using a guide part (29a) engaging in the rabbet groove of the sash (3), the support arm (11) is guided vertically and is supported against motions perpendicular to the sash plane. For the left-right repositioning of the fitting, the support arm (11) is connected to the hinge bearing (9) by a turning bearing (69) turning about a horizontal axis, the turning bearing being configured in its radial direction so as to have spring elasticity, in order to be able to engage and disengage a locking projection (77, 78) with the assigned locking recesses (75, 76).
