Abstract:
1. A refrigeration unit having a cabinet defining a storage cavity open at a front side covered by a door mounted to the front of the cabinet by two hinge assemblies at least one of which includes first and second mounting brackets spaced apart along a pivot axis on each side of a cam assembly including: a first cam having an undulating face surface including at least one oblique ramp surface and having an opposite back surface defining a key member engaging a corresponding key member of the first mounting bracket to prevent movement of the first cam member with respect to the first mounting bracket; and a second cam having a complementary undulating face surface with at least one ramp surface and being matable with the face surface of the first cam, the second cam also having an opposite back surface defining a key member engaging a corresponding key member of the second mounting bracket to prevent movement of the second cam with respect to the second mounting bracket; wherein the first cam can rotate with respect to the second cam when the door is opened and closed such that engagement of the opposing ramp surfaces biases the door toward the cabinet; wherein the second mounting bracket includes a stop member disposed to be in abutting relation with the first mounting bracket at a fully open position of the door so as to prevent further rotation of the door about the pivot axis.
