  • Patent number: 5487584
    Abstract: A support for a covering over one open top of a trailer box or other container which can be displaced from the opening when the covering is removed. The support has a series of parallel bows pivotally attached at one end to one side of the opening and configured at the other end to reversibly engage the other side of the opening. A perpendicular ridgepole is pivotally connected to the bows and assures that all the bows move in unison or are uniformly prohibited from movement. A lock on one bow is simultaneously released when a rope is pulled to pivot the bows from the support position to the retracted position. A method is disclosed of pivoting the bows at least partially out of the top opening of the box or container.
