Abstract: In a combined ventilator and window for installation in the roof of a motor coach, a panel 18 is mounted on angularly movable arms 28 so that the panel 18 can be moved between a closed position, opened positions in which either side of the panel 18 or either end of the panel 18 is opened, and an open position in which the panel 18 is parallel to and spaced from its closed position. The arms 28 are pivotally mounted on the frame 10 at 38 and have detent means 36, 40 to hold them in their alternative positions. The other ends of the arms 28 are pivotally connected to brackets 46, 74 depending from the panel, the latter pivotal connections being adapted to permit relative movement between the arms 28 and the panel 18 additional to movement about the respective axes of pivotal coupling.

Abstract: An opening roof comprises a frame which surrounds an opening in a roof of a vehicle and a rigid panel movable with respect to the frame to expose portions of the opening for ventilation purposes. The frame includes a flange which projects outwardly from a depending web to overlie a portions of the roof surrounding the opening. The frame is secured in position by clamping strips which act between the outer face of the web and the lower face of the roof remote from the flange, and screws which project through openings in the web to urge the strips into engagement with the web and the flange into engagement with the roof.

Abstract: A vehicle opening roof comprises a frame which surrounds a longitudinal opening in the roof of a vehicle and a panel assembly which is guided between spaced parallel guide rails forming the side members of the frame. A transverse mounting member is slidably guided between the guide rails and incorporates a handle-operated locking mechanism for engagement with a front rail at the front end of the frame to lock the panel assembly in the closed position. The mounting member also incorporates a first bracket for connection to a rigid panel, a second bracket for connection to a rigid flap at the forward end of a flexible covering, and a transmission mechanism for connection to the flap and operable in synchronism with the handle-operated locking mechanism to draw the flap down into engagement with the roof at the front end of the opening.
