The present invention relates to a casement (3) pivoting on a fixed window- frame (2) about only a horizontal axis, but laid non tilting due to a lower corner bearing (5) such as used on frame sections of vertically pivoted or tilt and turn casements, and an upper pivoting bearing (9) linked to the casement window by a suspension arm (11) which is enough flexible upwardly to follow the vertical movements made at the corner bearing (5). Owing to a guiding member (29a) engaging into the groove of the casement (3), the suspension arm is guided upwards and backed against movements perpendicular to the casement plane. To enable a right-left inversion the suspension arm (11) is connected to a pivoting bearing (9) through a bearing (69) turning about a horizontal axis and having a spring effect radially oriented in such a way as to enable a locking projection (77, 78) to be engaged in locking wells (75, 76) specially provided, or released therefrom.

La présente invention porte sur un châssis de fenêtre (3) tournant sur un cadre fixe (2) uniquement autour d'un axe horizontal, mais posé non basculable grâce à un palier d'angle inférieur (5) comme sur les armatures de châssis tournants et oscillo-basculants, et à un palier pivotant (9) supérieur relié au châssis par un bras de suspension (11). Le bras de suspension (11) est suffisamment flexible dans le sens vertical pour suivre les mouvements verticaux de réglage effectués au niveau du palier d'angle (5). Grâce à un élément guide (29a) s'engageant dans la rainure du châssis (3), le bras de suspension (11) est dirigé verticalement et soutenu contre les mouvements perpendiculaires au plan du châssis. Pour permettre une inversion droite-gauche, le bras de suspension (11) est relié à un palier pivotant (9) par un palier tournant d'axe horizontal (69) et à effet ressort dans le sens radial de manière à pouvoir mettre une saillie d'arrêt (77, 78) en prise dans les cavités d'arrêt (75, 76) prévues à cet effet ou à l'en dégager.
