  • Patent number: 6880610
    Abstract: A door system having first and second sets of panels with each set having leading and trailing panels, and having a different width. The leading panel of the first set includes a stop and the leading panel of the second set includes a pair of stops. First and second cable runs connected to a motor for driving the first and second sets of panels. The first cable run includes a clamp disposed within the stop of the leading panel of the first set and the second cable run includes a clamp disposed between the pair of stops of the leading panel of the second set. The space between the clamp of the second cable run and the pair of stops provides for a delayed engagement of the clamp of the second cable run with one of the pair of stops during initial movement of the second cable run. Notwithstanding the delayed engagement, the first and second sets of panels arrive at their full open positions simultaneously. Each set of panels includes a latch to connect the leading and trailing panels.
