发明名称 Ladder stand-off
摘要 A ladder stand-off includes a beam and two arms fixedly connected to the beam at two spaced apart points between the two ends of the beam. The two arms extend outward from the beam so as to be angularly divergent with respect to each other. A contact element is pivotally connected to a second, outer end of each arm. This arrangement allows the ladder stand-off to be used with flat, curved and corner surfaces. In one embodiment, the ladder stand-off is sized so that the distance between the fixed ends of the arms is less than the width of the ladder, while the distance between the outer ends of the arms is equal to or slightly greater than the width of the ladder. Furthermore, the distance between the outer ends of the arms is less than the length of the beam.
