Abstract (en)
Door hinge for the food retail, with a self-closing operating range between -5 and 80 degrees. The self-closing torque over the 80 degrees operation range is performed by two sets of springs. One set takes care for the closing torque in the upper part of the range and another set of springs takes care for the lower part of the range. The hinge is provided with a mechanism to prevent additional friction in case of misalignment between the two hinges of one door.
