Abstract
A concealed hinge between the lid and chest of a freezer has a hook shaped support bracket with a leg and bight. The bracket leg is mounted within one wall of the chest and the bight defines substantially diametrically opposed first and second pivots. A mounting structure is provided to pivotably secure the lid to the first pivot of the support bracket. A fixed point is defined within the lid and a compression spring member is provided between the fixed point and the second pivot of the bracket. The bracket leg is mounted within the chest wall by plastic components which function as a thermal barrier.
