Abstract: A closure device for a container having a lid hingedly attached at an attachment edge between one lower edge of the lid and a corresponding upper edge of the container comprises a spring means pivotally connected at a first end at a pivot point to a wing means capable of secure attachment to a hinged brace means. The brace means is mounted at its respective ends to an inside wall of the lid and a corresponding inside wall of the container. A second end of the spring means is adapted to be mounted on the inside wall of the container at such a distance from the brace means that when the lid is in a closed position the angle at the pivot point beneath the point exceeds 180 degrees, and when the lid is in an open position the same angle is less than 180 degrees.

Abstract: An opening roof assembly for a motor vehicle comprises a rigid panel adapted to close an opening in the vehicle roof with the panel supported at each side by front and rear guide means on respective guide tracks extending along each side of an opening in the vehicle roof and behind said opening below the vehicle roof. The front guide means permit pivotal movement of the panel about a horizontal axis at right-angles to the guide tracks and each rear guide means comprises a guide shoe arranged to be driven along the corresponding guide track and a chain comprising first and second links, the first link having a first pivot at one end connected to the shoe and a second pivot at the other end connected to one end of the second link, the other end of which has a third pivot connected to the roof panel.
