Hinge with compressions spring for counter-balancing weight of leaves
First Claim
1. A hinge with compression spring for counter-balancing the weight of leaves, e.g. covers, flaps or the like that are pivotable about a horizontal axis, particularly on freezer chests, wherein one end of the compression spring supports itself in the fixed hinged portion with the prestressing and its other end, by way of the end of a guide rod supporting the compression spring, engages the second hinge portion that is attached to the leaf, wherein the guide rod for the spring is supported at its lower end, through the interposition of a rocker, on a knife bearing of the fixed hinged portion, wherein brake jaws are disposed between the end of the guide rod supporting the compression spring and the associated end of the compression spring, said brake jaws being in the form of a double cone, one cone being at the side facing the rocker and guided in a complementary conical hole of the rocker and the other cone facing the compression spring.

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.
