19 Claims

1. A carriage arrangement for displacing a sash of a window or door in a displacement direction that is parallel to a main plane of a fixed frame of the window or door and for shifting the sash transversely to this main plane in a transverse direction while preventing movement of the sash relative to the fixed frame in a vertical direction, the transverse direction being perpendicular to the displacement direction and the vertical direction being perpendicular to the displacement direction and the transverse direction, wherein the carriage arrangement comprises the following:

a) a driving bar arrangement which can be arranged on the sash and which has a driving bar movable in a groove peripheral direction;

b) a carriage having a sash part which can be fastened to the sash and a roller part which can be shifted transversely to the main plane and has a plurality of rollers for displacement in the displacement direction;

wherein the driving bar arrangement comprises a control projection which is arranged or formed on the driving bar and which is guided in a control slot in the roller part, which control slot is formed at least sectionally obliquely to the main plane, wherein a movement of the driving bar causes the roller part to shift transversely to the main plane;

c) a first roller bearing guide via which the sash part is supported transversely to the main plane on the roller part during the movement in order to offload the weight of the sash onto the roller part;

wherein the sash part is supported on the roller part in the displacement direction via the first roller bearing guide wherein forces occurring on the roller part in the displacement direction are configured to be introduced into the sash part via the first roller bearing guide;

wherein the first roller bearing guide has a first roller bearing bed on the sash part and a second roller bearing bed on the roller part, and wherein a plurality of rolling bodies of the first roller bearing guide are between the first and second roller bearing beds and are configured to allow movement of the sash part relative to the roller part in the transverse direction while resisting movement and transferring forces of the sash part relative to the roller part in the displacement direction;

wherein the pluralities of rolling bodies are configured to transfer a vertical force along the vertical direction between the first and the second roller bearing beds;

wherein the pluralities of rolling bodies are configured to transfer a displacement force along the displacement direction between the first and the second roller bearing beds; and

wherein the pluralities of rolling bodies are configured not to transfer a transverse force along the transverse direction between the first and the second roller bearing beds.
