  • Patent number: 10184293
    Abstract: A ladder unit is slidably joined to an edge of or beneath a working surface by a mounting frame having a roller assembly or other slidable means. The ladder unit includes a stair assembly that is rotatably mounted to the mounting frame by a hinge, and configured to rotate between an open position, in which a support provided on the stair assembly does not contact the working surface, and a closed position, in which the support contacts the working surface. In this regard, the ladder unit may be slidably moved from location to location along the working surface when the stair assembly is in the open position with substantially low friction, and may be stabilized in a location for use when the stair assembly is in the closed position.
