The up-and-over door comprises a door panel (1) mounted slidably in an articulated manner along the two vertical edges of the aperture associated with the door, in order to allow this door panel to tilt between a vertical closed position and an open position. The door possesses a first fixed slideway (7) extending along one vertical edge of the aperture and a slide (8) mounted on this slideway, this slide being connected to means for controlling its movement on the slideway. A second slideway (9) is fastened along the edge (3) of the door panel (1) adjacent to the first slideway (7). This second slideway (9) forms a particular angle (a) with the panel (1), the vertex (9a) of this angle (a) being adjacent to the lower edge (1a) of the panel (1). A second slide (10) is mounted on the slideway (9) and is connected to the first slide (8) by means of a joint (11) perpendicular to the plane in which this slideway (9) is located. The invention is used for up-and-over garage doors. <IMAGE> |
