A flap member, e.g. a trunk lid of a motor vehicle, is pivotally mounted on a framework, e.g. a motorcar framework. The flap member is assisted in its upward movement by a gas spring. The thrust of the gas spring biases the flap member towards an upper position. In this upper position further upward movement of the flap member is locked by a relief pressure valve between the working chambers of the gas spring. By applying external force to the flap member assisting the thrust of the gas spring, the flap member may be moved beyond said upper position whil...
In a construction assembly comprising (a) a basic construction unit; (b) a flap member pivotally mounted on said basic construction unit for pivotal movement about a substantially horizontal axis through a basic path of angular movement between a first or lower angular position and a second or upper angular position; (c) at least one gas spring pivotally connected to said basic construction unit and to said flap member for assisting movement of said flap member within said basic path of angular movement against the action of gravitational forces, said ga...
