PURPOSE: A fatigue load dispersion system of a folding door assembly is provided to prevent an excessive load from being applied to an upper rail when a folding door is opened. CONSTITUTION: A fatigue load dispersion system of a folding door assembly is composed of multiple folding doors(300). The folding doors are foldably coupled to each other using hinges and have upper and lower hangers(310,320). The upper and lower hangers are rolled along upper and lower rails(100,200). When the folding doors are closed, the folding doors are rolled through the upper hanger. When the folding doors are opened, the folding doors are rolled through the rolling contact between the lower hanger and the lower rail. |
