  • Patent number: 6688657
    Abstract: A dual hinge door assembly is provided that enables selective opening of one side of a two sided door or removal of the door. The two sides of the door have identical assemblies that connect via a horizontal bar. Actuating a switch causes the bar to move horizontally in one of two directions. Movement of the bar causes assemblies on each side of the door to rotate and translate the horizontal motion of the bar to vertical motion of a set of lock pins, and causes the handle on the side of the door selected for opening to become visible to the operator. Upon pulling the handle, the side of the door adjacent to the lock will open while the opposite side remains stationary. Alternatively, the assembly may be modified to cause both handles to release. The operator may then pull both handles to remove the door from the housing.
