ABSTRACT:
A spring-biased hinge for the weight compensation of two structural members that are to be pivotably interconnected by means of the hinge for pivotal motion about a horizontal axis, particularly for counter-balancing the weight of a lid pivotable with respect to a freezer chest, comprises first and second hinge members pivotally interconnected by a hinge pin and securable one to each of the structural members. A precompressed spring is supported at one end by the first hinge member and at its other end by a guide rod for the spring. The guide rod is axially displaceable and acts on the second hinge member. At its said one end, the spring is supported by means of a cradle member which can rock on a bearing edge provided on the first hinge member, brake shoes for acting on the guide rod being interposed between said one end of the spring and the cradle member.
