Claim 5:
6. A door guide of a vertically stacking door, comprising:
a vertical track;
a first curved track portion;
a second curved track portion;
a first horizontal track portion coupled to the first curved track portion;
a second horizontal track portion coupled to the second curved track portion; and
a ramp coupled to the vertical track and located below the first curved track portion and the second curved track portion, wherein the ramp is adapted to interact with a cam lever of each one of a plurality of panels of the vertically stacking door that are guided through the vertical track, wherein interaction between the ramp and the cam levers causes the panels of the vertically stacking door to separate while moving towards the first curved track portion and the second curved track portion, wherein the ramp comprises an inclined surface which interacts with the cam lever located on an end cap of a first panel of the plurality of panels to cause an adjacent second panel of the plurality of panels to separate from the first panel of the plurality of panels, wherein the ramp causes a second cam wheel of the cam lever of the first panel to pivot the cam lever of the first panel relative to the first panel which causes a first cam wheel of the cam lever of the first panel to apply a force against a cam surface of the adjacent second panel to cause the adjacent second panel to separate from the first panel as the first panel and the second panel move towards the first curved track portion and the second curved track portion.
