Abstract

The safety catch consists of a spring mounted between the hinged lid and the container. The spring is deformable like a bending spring, and is loaded in an axial direction. The extended or almost extended position of the spring corresponds to, resp. determines the maximum angle of opening of the lid. The buckling resistance of the spring, is larger, when in open position, or the same, or smaller, when closed, than the power applied to it by the lid. The spring may consist of a helical spring, or a multi-layer leaf spring. Pref. the spring with the hinge lid open is arranged at right angles to the line bisecting the angle between the open lid and the fixed support in relation to the axis of rotation of the angle.
