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.

Abstract: A rolling device for a sliding leaf (2) of a door or window and having a slide (7) aimed at being accomodated in the slit (24) provided for in the lower edge (23) of a profile (4) defining the lower rail (3) of the leaf (2), this slide (7) resting against a metallic reinforcement (6) or a horizontal wall (44) located in the inner portion (5) of the profile (4). The slide (2) is also provided a hooking-in member (27, 28), cooperating with the transversal edges (29, 30) of the slit (24), defined by a horizontal rim (31) at the level of its transversal ends (17, 17A), at least one horizontal rim (31) being subjected to springy restoring member (33) allowing to withdraw the hooking-in member (27) in order to allow the passing through, by snapping in, of this latter, and its removal, the hooking-in member (27, 28) being completed by a retaining member (47) capable of vertically immobilizing the rolling device (1) in the slit (24) of the profile (4).
