ABSTRACT:
A door operating mechanism is provided for rotatably switching a door relative to a base between a closed position and an open position. A sector gear is disposed in a support arm projected from the door. A rotary gear is disposed substantially in the center of the arc of the sector gear. A first gear of the base has internal teeth disposed to engage the sector gear. A second gear of the base is resiliently and displaceably disposed to engage the rotary gear. The door is rotatably disposed along a track corresponding to the first gear via engagements between the first gear and the sector gear, and engagements between the second gear and the rotary gear. A load received by the door in the closed position towards the bottom of the base is absorbed by resilient displacement of the second gear.
