Double bottom slider system and mechanism

A double bottom slider system and mechanism for a sliding door assembly comprising an inner door panel and an outer door panel slidingly engaged between an upper guide and lower track to allow the doors to translate relative to each other;

• a locking system located on the top portion of the lower track made up of an inner door gear element attached to a torque loading device, such that the inner door gear element is urged clockwise by the torque loading device, with a protruding element in contact with the inner door panel meshed with an outer door gear element with a protruding element in contact with the outer door panel;
• the inner door gear element loaded in the clockwise direction with the torque device such that when the inner door panel is fully closed, the protruding element on the inner door gear element is locked against the edge of the inner door panel and the protruding element on the outer door gear element is disengaged from the edge of the outer door panel;
• the outer door gear element rotated in the clockwise direction, such that the protruding element on the outer door gear is locked against the edge of the outer door panel and the protruding element on the inner door gear element is disengaged form the edge of the inner door panel;
• wherein, to lock the inner door panel, the inner door panel is moved toward a closed position and the outer door panel is moved away from the closed position, therefore the inner door gear element loaded in the clockwise direction with the torque device such that when the inner door panel is fully closed, the protruding element on the inner door gear element is locked against the edge of the inner door panel and the protruding element on the outer door gear element is disengaged from the edge of the outer door panel;
• and
• wherein, to lock the outer door panel, the outer door panel is moved toward a closed position and the inner door panel is moved away from the closed position, therefore, the edge of the inner door panel contact the protruding element of the inner door gear, so that the outer door gear element is rotated the clockwise direction, the protruding element on the outer door gear is locked against the edge of the outer door panel and the protruding element on the inner door gear element is disengaged form the edge of the inner door panel.
